The basic FlexLink conveyor

Straight conveyorA FlexLink conveyor is based on an aluminium conveyorbeam guiding a plastic multiflexing chain. The chain trav-els on low-friction plastic slide rails. Products to be con-

veyed ride directly on the chain, or on pallets. Guide railson the sides ensure that the items stay on the track, ifnecessary together with angle plates on the sides of theconveyor. Optional drip trays under the conveyor trackkeep the floor free from waste fluids.

The XB conveyor uses additional half-beams on eachside of a middle beam to create a wide and stable track.

Drive units and idlersA number of drive unit configurations are available tomove the conveyor chain:

The end drive unit pulls the chain from one end of the

conveyor. The chain returns on the bottom side of thebeam, passing an idler end unit at the other end.

Intermediate drive units are located at some interme-diate point of a conveyor, with idlers at both ends.

If chain return on the bottom side is not desired orpossible, catenary drive units can be used.

Another alternative for light loads is the horizontalbend drive unit, especially suitable for alpine-shapedaccumulation conveyors.

BendsChange of direction is accomplished by means of bendunits:

Lowest friction is obtained by using horizontal wheelbends, where the bend force is taken by a wheel.

For large diameter horizontal bends, horizontal plainbends are a suitable alternative.

Vertical change of direction is made by means of ver-tical plain bends, or (if a 90 change of direction isdesired) idler bend units.

GuidanceProducts must be guided along the conveyor:

Guide rails keep the products from falling off the sidesof the conveyor. Guide rail brackets hold the guide railin position.

In verticals, front pieces are used to keep the productsfrom falling.

Conveyor supportComponents for support of conveyors include:

Feet in various configurations

Support beams up to 88 mm 176 mm cross-section

Beam support brackets to connect conveyor beam tosupport beam.

Conveyor engineering guidelinesFlexLink conveyor selection

IntroductionThis section of the FlexLink catalogue contains

selection guidelines to assist you in selecting the right

system for your application basic technical information that applies to FlexLink

product lines XS, XL, XM, XH, XK, and XB.

Selection procedureThe selection guidelines are based on thousands of suc-cessful FlexLink installations world-wide. The followingbasic procedure is recommended when selecting a suit-able FlexLink size.

1 Make a preliminary system selection based on thegeneral recommendations below.

2 Make an outline of the conveyor, with bends, driveunits, etc. shown.

Then check the system as follows:

3 Calculate the total load based on product weight, dis-tance between products, accumulation distance, andconveyor length.

4 Determine the service factor by specifying the fre-quency of starts and stops. The service factor will beused as a derating factor when calculating the permis-sible load.

5 Calculate the chain tension from the formulae on the

following pages.6 Compare the resulting chain tension with the capacity

of the chain and drive unit selected. If the capacity isnot sufficient for your application, shorten the con-veyor if possible, or select a system with highercapacity.

For additional information please consult your local Flex-Link representative.

Basic system selectionThe six standard FlexLink chain sizes XS (44 mm), XL(63 mm), XM (83 mm), XH (103 mm), XK (102 mm), andXB (175/295 mm) together cover a wide product range.To select the right chain size for your application, con-sider the following.

Product dimensions

A product can be much wider than the chain. If the pointof balance is located in the centre of the product, thewidth of the product can be three to four times the widthof the chain. Supporting guide rails may be necessary.Testing is recommended.

Product weight

Product weight is important when selecting chain size.Each chain has a maximum traction force. If severalheavy items are to be conveyed, you must calculate thetraction force required. If products are to be accumulated(stopped in a queue, with the chain moving), the tractionforce is increased even more. The Technical data sec-tion includes formulas for chain tension calculations.

Conveyor functions available

Most conveyor functions are available in all six sizes.Note however that there are differences with regard todrive unit variants and chain types. Sizes XL and XMinclude components for vertical wedge conveyors.

Floor space available

Sometimes the floor space will require use of the small-est conveyor possible.

Compatibility with other equipment

In some applications, interfacing with other equipmentcould be made easier by using one of the FlexLink sizesrather than other sizes. Some manufacturers havedesigned equipment with direct connection to FlexLinkconveyors.

Chain tension calculations

Why calculate?There are at least two reasons why you should estimateor calculate the maximum tension of the chain before youdecide on a conveyor configuration:

Drive unit capacity

Tension limit of conveyor chain

In most cases, both the drive unit capacity and the ten-

sion limit of the chain far exceed the requirements of theapplication. This is true for short, low-speed conveyorsand for light loads. If you are in doubt, however, alwayscalculate!

Drive unit capacity limitThe required motor output power P depends on

Traction force F

Chain speed v

The following equation applies:

The maximum permissible traction force of the variousdrive units is shown in the following table:

Chain tension limitSee diagrams 1 and 2.

Diagram 1

Maximum chain tension versus conveyor length

Diagram 2

Maximum chain tension versus conveyor speed

Service factorThe maximum permissible chain tension (see diagrams 1and 2) depends on the number of conveyor starts andstops per hour. Many conveyors run continuously,whereas others start and stop frequently. It is obviousthat frequent starts and stops increase the stress on thechain.

The service factor (see table below) is used to deratefor high frequency of starts and stops and for high chainspeeds. Divide the tension limit obtained from the graphsby the service factor to get the derated tension limit. Ahigh service factor can be reduced by providing a softstart/stop function.

ImportantThe chain tension calculations are made to ensure thatthe capacity of the drive unit is sufficient, but not exces-sive, in relation to the strength and friction of the chain.The calculations do not take into account the increasedwear resulting from the higher friction in plain bends.

Chain tension calculations (continued)

Chain tensionThe tension building up in the chain can be divided intoseveral components:

1 Friction between unloaded chain and slide rails, forexample on the underside of the conveyor beam.

2 Friction between loaded chain and slide rails(Figure A).

3 Friction between accumulating products and top sur-face of chain (Figure B).

4 Gravity force acting on products and chain in inclinesand verticals (Figure C).

5 Added friction in plain bends. This friction is propor-tional to the chain tension on the low-tension side ofthe bend. This means that the actual friction dependson the position of the bend in the conveyor (Figure D).

Traction forceThe traction force F required to move the chain dependson the following factors:

Conveyor length............................................ LProduct gravity load per m

Transport ..................................................... q pAccumulation .............................................. q pa

Chain gravity load per m............................... q cFriction coefficientBetween chain and slide rail ....................... rBetween chain and products ...................... p

Bend factor, plain bend (hor./vert.) ........... k Inclination angle............................................

Bend factorsEach plain bend introduces a bend factor k . This factoris defined as the ratio between chain tension measured

just after the bend and that measured before the bend.The bend factor depends on

the amount of direction change of the bend (angle )

the coefficient of friction, r, for the friction betweenchain and slide rails.

When the conveyor is dry and clean, the friction coeffi-cient, r, will be close to 0,1.

The bend factor must be used since the frictional forceof a plain bend depends not only on the chain and prod-uct weight and the coefficient of friction, but also on theactual tension of the chain through the bend. This tensioncauses additional pressure to the conveyor beam andslide rail from the chain. The additional force is directedtowards the centre of the bend.

Calculation of this additional force is more compli-cated, since the chain tension varies through the con-veyor, being maximum at the pull side of the drive unit,and virtually zero at the inlet of the return chain. Thebend factor provides a means of including the added fric-tion in bends into the calculations.

The same bend factors apply to horizontal and verti-cal plain bends. See the table.

Note

Horizontal plain bends should only be used in excep- tional cases. For normal applications, use wheel bends.

Chain tension calculations (continued)

Basic calculation procedureChain tension for FlexLink chains is determined by use ofsuccessive calculations. A number of elementary casescan be combined to cover most situations. The generalidea will be shown by means of examples on the follow-ing pages. When calculating the chain tension, followthese steps:

Divide the conveyor Divide the conveyor into anumber of elementary sec-tions. Start at the end far-thest away from the driveunit. Each section shouldconsist of a straight piece ofconveyor up to and includ-ing the next plain bend (hor-izontal or vertical).

Wheel bends are considered equivalent to straightsections. This means that a conveyor without plain bendscan be treated as one elementary section.

Calculate the sum of forces and multiply by bend factor

Start at elementary section L 1 at the end farthest awayfrom the drive unit. For each successive elementary sec-tion L k: calculate the traction force F k required to movethe chain along the elementary section.

1 Calculate the sum of all counteracting forces:

Transport friction. See Figure A, page 23.

Accumulation friction (if any). See Figure B, page 23.

Gravity (inclined/vertical conveyor). See Figure C,page 23.

The counteracting force F k-1 of the previous section.(The first section has no such counteracting force,hence when calculating F 1, make F 0 equal to zero.)

2 Multiply the sum of forces by the bend factor. See Fig-ure D, page 23. (If the section does not include anyplain bends, the bend factor is equal to 1.)

Repeat the calculation up to and including the sectionwith the drive unit. The resulting force is the traction forcerequired to move the conveyor.

Horizontal conveyor with no plain bends

If the conveyor contains noplain bends, the whole con-veyor can be treated as onestraight section with a totallength of L from idler endunit to drive unit. Use thefollowing formulas. (Desig-nations: page 23.)

Without accumulation:

With accumulation:

Horizontal conveyor with plain bends

Divide the conveyor into elementary sections, eachincluding one vertical or horizontal plain bend. For eachelementary section (length L k), use the following formu-las, starting with section L 1. (Designations: page 23.)

Without accumulation:

With accumulation::

Repeat with all conveyor sections, until you obtain thetotal traction force required at the drive unit.

Examples

The examples on the following pages provide approxi-mate values of the resulting chain tension. To get moreaccurate values, the influence of the return chain on thebottom side of the beam must be considered. In mostcases, this influence can be ignored. However, if the con-veyor includes several plain bends, or if the goods weighless than two times the chain per unit of length, a com-plete calculation must be made. For a complete calcula-tion, start at the return side of the drive unit.

If the tension is too highIf the calculated traction force exceeds the chain capacityor the drive unit capacity, some modification will be nec-essary.

Shorten the conveyor.In some cases, the layout could be changed so thatthe conveyor becomes shorter.

Divide the conveyor into two separate conveyors withindividual drive units.

F=L(q c+q p)r

F=L[(q c+q pa )r+q pa p]

Fk=[Fk-1+Lk(qc+q p)r]k 1

Fk={Fk-1+Lk[(qc+q pa )r+q pa p]}k 1

Example 1: Horizontal conveyor (continued)

Comparison with ratingThe result of the calculations can now be compared withthe maximum permissible chain tension. It is necessaryto check tension with regard to a) conveyor length (dia-gram 1, page 22) and b) conveyor speed (diagram 2,page 22). The calculated value shall be compared withthe lower of the two values obtained.

Tension limit The maximum chain tension for a 15 m XL conveyor is500 N (diagram 1, page 22).

The maximum chain tension for a conveyor speed of18 m/min is 400 N (diagram 2, page 22). The lower value,400 N, is the basic tension limit. With a start/stop fre-quency of 50 per hour, the service factor is 1,6 (see tableon page 3). This means that the basic tension limit mustbe derated to 400/1,6 = 250 N.

Summary

a) Without accumulation:

F3 = 108,4 (250 N).

This conveyor should be redesigned. If possible, shortenthe accumulation distance, reduce the speed, or switchto an XM conveyor.

c) With accumulation on 2,5 m of L 3:

F3 = 169,7 N (

Example 2: Inclined conveyor (continued)

Section 2

Section 1 causes a counteracting force F 1 which must beadded. Gravity forces in the bend are ignored.

F2=[35,5+2 (7,4+49) (0,1 0,5+0,87)+0,5 (7,4+49) 0,1] 1,4 =198,9 N

(Special case: section 2 is vertical)

The same formulas can be used when calculating thechain tension of a vertical conveyor. In a vertical conveyor(with two 90 vertical bends) angles and are both 90 .Since sin 90 =1 and cos 90 =0, the formula is simplifiedto:

indicating that the gravity component is the only force act-ing along the vertical section. Gravity forces in the bendare ignored.

Section 3

Sections 1 2 cause a counteracting force F 2 which mustbe added to the friction obtained from the basic formula:

F3=198,9+2 (7,4+49) 0,1 =210,2 N

Comparison with rating

The result of the calculations can now be compared withthe maximum permissible chain tension.

Tension limit

The maximum chain tension for an 8 m XL conveyor is500 N (diagram 1, page 22). The maximum chain tensionfor a conveyor speed of 5 m/min is also 500 N (diagram 2,page 22). With a start/stop frequency of 10 per hour theservice factor is 1,2 (see table on page 22). This meansthat the basic tension limit must be derated to 500/1,2 =416 N.

Summary

Since F 3 is calculated to 210,2 N (

Chain strength and expansion vs. temperature

Friction between chain and slide rail

The coefficient of friction is normally the lower value atthe startup of a new conveyor. It will increase as the con-tact surfaces wear in. Lubrication will reduce the coeffi-cient of friction.

Friction between chain and productIn most cases, the coefficient of friction for contactbetween plain chain and product is between 0,1 and0,35. Always measure the friction between the chain andthe actual product. The typical friction between roller topchain and product (inner friction in rollers) is in the orderof 0,05 to 0,08. The actual friction coefficients depend onsurface smoothness.

For inclines exceeding 5 (1:10) it is necessary to usea cleated chain. Chain sizes XL, XM, and XH are availa-ble with high friction tops, suitable for inclines up to 30 (1:2).

Maximum conveyor lengthThe maximum length of a conveyor depends on the ten-sion in the chain, the speed, and the capacity of the driveunit.

It is important to calculate and compare the maximumchain tension and the capacity of the drive unit in the fol-lowing situations:

Heavy load Accumulation

Vertical conveyor

High speed

Long conveyor

Conveyor includes horizontal or vertical plain bends

Frequent starts and stops (high service factor).

Temperature limits

A FlexLink conveyor can operate continuously at environ-ment temperatures from 20 C to +60 C. Temperaturesup to 100 C can be tolerated for short periods (cleaning,rinsing).

Technical data (continued)

High speed applicationsConveyor speeds over 60 m/min. require special designconsiderations. Since the amount of material lost due toabrasive wear is directly related to distance travelled,higher speeds will result in faster wear and require morefrequent maintenance. Careful attention to design detailswill reduce the rate of wear, increasing the amount of runtime between replacement of wear parts. The primarywear parts of a FlexLink conveyor are the slide rail andthe conveyor chain. Design parameters to be consideredare:

Load

A major factor affecting wear is the load on the conveyor.The chain tension at the drive is an indicator of the totalload on the conveyor. Chain tension for high speed appli-cations can only be a fraction of the maximum tractionforce of the drive unit. Always do chain tension calcula-tions for high speed applications. The following recom-mendations include methods to reduce the load on theconveyor.

Bends

Wheel bends should be utilized whenever possible. If theapplication cannot accommodate wheel bends, plainbends with radii of at least 1000 mm should be used. Theextra support rail should be used on the inside of all hor-izontal plain bends. PVDF slide rail should be used onthe inside of horizontal plain bends and on all verticalbends because of the amount of heat generated in thisarea. Also, when using plain bends, do not make a totalchange in direction of more than 90 degrees with any oneconveyor.

Conveyor length High speed conveyors should be limited to a total lengthof 15 m. This is only a guideline. It can be higher forstraight running conveyors with light loads, but should bereduced for heavy loads with plain bends.

Motor control

All high speed conveyor motors should be equipped withsoft starting and stopping motor controls. Conveyorsshould be programmed to shut off when an upstream ordownstream interference interrupts product flow.

Lubrication

A very small amount of lubrication can have a significanteffect on the performance and reliability of any conveyorsystem, but is especially effective in high speed applica-tions. One drop of silicone on the slide rail per hour of runtime is enough to reduce wear to almost nothing. In appli-cations where silicone is prohibitive, other lubricants can

be used just as effectively. Be sure to investigate chemi-cal compatibility when choosing a lubricating agent. Anyconveyor running faster than 80 m/min. should be lubri-cated.

Other considerations

The higher the speed of the conveyor the more importantit is to maintain the chain slack at the drive (see Mainte-nance page near the end of this section). The inspectioninterval should also be reduced since minor misadjust-ments can result in very rapid wear. If you have any con-cerns about your high speed application, please contactyour local FlexLink sales office for assistance. Ear sound

protection will be required for anyone working in closeproximity to a high speed conveyor. The following chartshows the expected noise contribution of high speedconveyors measured from 1 m away.

Effective track lengths

Track length definitionThe following tables list the effective track lengths for var-ious FlexLink components. These should be consideredwhen determining how much conveyor chain is requiredin a system. The lengths are rounded up to the nearest50 mm.

The effective track length is the total length of chainrequired through a bend or drive unit. The value for two-way chain applies when the chain returns on the bottomside.

Aluminium profilesAluminium is very resistant to corrosion in most environ-ments because of the thin natural oxide layer formed onthe metal surface when it is exposed to oxygen. The layeris hard and tight, and adheres well. In spite of its limitedthickness (0,01 m) it prevents further oxidation. Underunfavourable conditions, however, corrosion will takeplace. Normally, this will only affect appearance.

Compatible with most common chemicalsThe FlexLink conveyor components can withstandlengthy contact with most chemicals used in normalworkshop environments. It is, however, necessary toavoid acids with pH lower than 4, bases with pH above 9,and lengthy exposure to chlorinated hydrocarbons suchas trichloroethylene.

The following tables specify the resistance of thematerials used in FlexLink components to various chem-icals. For some chemicals, the reactions depend on con-centration and form of the chemical. A higherconcentration of an acid will cause more swelling of thematerial subjected to it. Also, the liquid form of a gasresults in more brisk reactions.

Chemical testIf you are doubtful about whether our materials will with-stand your special environment, you should perform achemical test. The following procedure, which tests theabsorption of the material by measuring the swelling, issuitable for plastic materials. It should be performed at

two temperatures, 20 C and 60 C. The 60 C test rep-resents long term exposure at room temperature.

1 Put a sample of the material into the chemical solu-tion.

2 Measure the change in weight and length after 1, 2, 4,and 7 days in the solution. If the relative change ofweight, length, or other geometric change exceeds1 %, the test is considered negative, i.e. the chemicalis not compatible with the material.

Static electricityLow conductivity

The standard plastic materials used for conveyors allhave low electrical conductivity. This means that staticelectricity can build up on the conveyor. If the chain runson plastic slide rails, no inherent discharge path exists forthe static electricity.

When a conveyor is running under normal operating con-ditions but without products, the following static build-upcan be measured:

At the drive unit .................................. 2000 2500 VAt the idler end unit ............................ 400 500 VAt a wheel bend.................................. 400 500 VAt a straight section............................ 300 400 V

Depending on the shape and material, a product runningon the conveyor can also build up static electricity. Theworst case is with accumulated products. Discharge isnormally taking place when the products are transferredto or from the conveyor.

In static sensitive applications, a number of measurescan be taken to reduce the risk of excessive staticcharges.

1 Ensure that the relative humidity is minimum 40 %.

2 Install static discharge wipers immediately beforesensitive points on the conveyor.

Components for static sensitive environments

Some FlexLink chains, slide rail, and guide rail cover canbe ordered in carbon loaded or ISD versions. The carbonloaded material has high conductivity whereas the ISDmaterial is dissipative.

Contact your FlexLink Systems representative for addi-tional information.

WearThe degree of wear on a conveyor depends on a numberof factors, such as

Running time

Load, contact pressure

Speed

Product accumulation

Sharp or rough products

Chemicals

Foreign particles e.g. chips, grinding particles, brokenglass, sand, sugar

Temperature

Plain bends

Try to minimize the running time for the conveyors bystopping them when there is no transport.

Multiple horizontal and vertical plain bends in a conveyorwill often result in increased wear. One reason is that thefriction losses are large in plain bends. Also, the contactsurface between chain and slide rail is small and thechain pull is acting towards the slide rail in the bends.

The amount of wear will be highest during an intro-ductory period, and will decrease when the surfaceshave adapted to each other. Lubrication will reduce wear.

Run-in period Two to three weeks are usually enough as a run-inperiod. During this time, the conveyor should be cleaneda couple of times, to remove dust. After run-in, wear willbe minimal, unless particles from the product or processreach the conveyor continuously.

Chain elongation

Especially during the run-in period, and if the load isheavy, the conveyor chain will slowly increase in length.This effect will be most obvious for long conveyors. Aftercontinuous operation for two weeks, it is often possible to

remove a couple of chain links. After this period, we rec-ommend a check every 3 6 months.

Ultra-violet lightThe plastic material used in the FlexLink conveyor chainwill deteriorate slowly if exposed to strong ultra-violetradiation from industrial UV sources.


19/132


Conveyor noise level

IntroductionThe noise generated by the conveyor chain will decreaseafter a few days of operation. Generally, a higher speedwill result in a higher noise level, though still less than thegeneral noise in a factory environment. At high speeds,large-radius plain bends are quieter than wheel bends.The actual noise level depends on several factors:

The product on the conveyor

The installation premises

Surrounding equipment

The conveyor layout and dimensions

Typical noise levels for a conveyor with an end drive unitare shown in the following tables. The noise level wasmeasured at three points for each conveyor type, at a dis-tance of 1 m from drive unit (A), bend (B), and idler endunit (C), at the same level as the top of the conveyor. Thenoise level was measured at speeds from 5 m/min up to60 m/min.

Slide rail selection guidelines

Slide rail overview

Characteristics

The slide rail is used to provide a low friction and wearresistant track for the chain. There are slide rails in fourdifferent types of materials, each with different character-istics:

1 High density polyethylene2 Ultra-high molecular weight polyethylene3 Polyamide-polyethylene4 Polyvinylidene fluoride5 Stainless steel

The coefficient of friction is normally closer to the lowervalue at startup of a new conveyor. It will increase as thecontact surfaces are wearing in. Lubricants will reducethe coefficient of friction.

Considerations when selecting slide railEach of the slide rails has its own characteristics and issuitable for different types of applications.

Polyethylene slide rail is suitable for most standardapplications.

In environments where high resistance to chemicalsis important, PVDF slide rails are recommended.

Steel slide rails in combination with PVDF slide rails inbends can be a good combination where larger particlessuch as chip occurs.

UHMW-PE has the highest wear resistance and canbe recommended in applications with:

Accumulation

Transport of heavy parts

High speed

Abrasive particles

Requirements on low dust generation

Chemical resistance

It is important to find out if there is an influence fromchemicals in the system. See the chemical resistance list(page 34). For instructions on resistance testing refer topage 35.

Temperature range

The maximum continuous temperature is 60 C forXLCR 25 and XLCR 25 U and 100 C for XLCR 25 P andXLCR 25 H. All slide rail types can be used down tominus 40 C.

Horizontal plain bends

The contact pressure between the chain and the slide railis very high in the inner bend of horizontal plain bends. Itis important to use the PVDF slide at this location if thespeed is high as there will be increased temperaturesthat may cause melting of other slide rails. This, however,will result in somewhat higher wear on the chain.

InstallationIt is important that the slide rail be properly mounted andanchored to the conveyor beam. See Appendix A,Page 1.

The length of slide rail depends on the application. Itis important to cut the slide rail to shorter sections allow-ing for elongation in high load areas such as after hori-zontal and vertical plain bends and in accumulationzones.

It is also recommended to use short slide rails (2 to3 m) where chemicals might affect the slide rail.

Maintenance

ChainThe chains are made of acetal resin which has an excel-lent combination of strength, wear resistance, chemicalresistance, impact strength and temperature range.

Chain failures like breakage and high wear mightoccur if the actual chain pull is higher than the permissi-ble chain pull. There is also a big risk for slip-stick at highchain pulls.

There is an arrow on the side of all chain links show-ing the proper running direction for the chain. The chainshould run without pre-tension. Pre-tension might resultin uncontrolled chain pull and lead to chain failure. Forthis reason it is important that there is a visible chainslack at the drive unit when the conveyor is running.

The chain has a good impact strength. A broken link isa sign that something is wrong along the conveyor. Fre-quent failures can be attributed to broken cleated linkscaused by jamming at the loading or unloading of theconveyor.

It is important to replace broken or damaged chainlinks, or the broken link might damage the slide rail or thefeed-in guides for the return chain at the drive unit.

Chain elongation

The chain is made of an elastic material. In addition tothe elastic elongation, the chain will exhibit elongationbecause of material creeping. The magnitude of the elon-gation depends on the chain pull. The elongation willshow up at the take up side of the drive unit. Too muchchain slack may cause wear at the chain entry point inthe drive unit. Regular inspections of the chain elonga-tion are important. The chain should be shortened after a

run-in time of 50 hours. Further inspections should bemade after 250 and 500 hours and then every 500 hours.Frequent inspections are more important if the conveyoris long or has large/heavy loads.

The plastic pivot should be replaced if the steel pinconnecting the chain is removed for shortening the chainor replacing damaged chain links. Check that the steelpin is centered after it has been mounted and that thechain is flexible in the joint.

Slide railLubrication

Lubrication of the surface between the slide rail andchain will result in a lower coefficient of friction and longerlife.

Inspection

Check the slide rail in horizontal and vertical plainbends after every 250 hours of operation. The chaincan stay in place during this inspection. Replaceworn-out slide rail.

Remove the chain from the conveyor and inspect theslide rail carefully at least once a year or after2000 hours of operation (plain bends: 500 hours).Check wear and anchoring. Replace worn-out sliderail.

Drive unitsEach drive unit can be equipped with different brandsand types of worm gear motors. Follow the maintenancerecommendations of the motor/gear manufacturer.

Transmission chain

The conveyors are normally equipped with roller trans-mission chains. The transmission chain will elongate andshould be inspected after 50, 250 and 500 hours, andthen every 500 hours. It should be lubricated andstretched if needed.

Safety clutch All drive units are equipped with friction type safetyclutches. The safety clutch is mainly a safety device forthe conveyor that prevents damage at overload. The slipclutch should be set so that it does not slip under normalmaximum load. Never run the conveyor without transmis-sion cover.

There are two different designs of the safety clutches.One type is used for 3/8" and one for 1/2" roller chains. Itis important to unload the conveyors before releasing theclutch.

For instructions on adjusting the safety clutch, seeAppendix B, page 374.


23/132


General safety and design considerations

IntroductionWhen designing a conveyor system, it is necessary toconsider all of its aspects in order to achieve an opera-tional installation which is reasonably safe for all people

involved in its use or maintenance. For conveyors thechain is generally the critical factor to consider withguarding.

SafeguardingAll pinch and shear points as well as other exposed mov-ing parts that present a hazard to people at their worksta-tions or their passageways must be safeguarded.Overhead conveyors must be guarded to prevent objectsfalling. Cleated conveyor chains are more hazardous increating more pinch and shear points than plain conveyorchains.

Safeguarding can be achieved by: Location

Locate the hazardous area wherever possible out ofthe area occupied by personnel.

GuardsMechanical barriers preventing entry into the hazard-ous area, or protecting against falling objects.

Control devicesMachine controls which prevent or interrupt hazard-ous operations/conditions.

WarningsInstructions, warning labels, or sound/light signalswhich alert to hazardous conditions.

Safeguarding should be designed to minimize discomfortor difficulties to the operator. Bypassing or overriding thesafeguarding during operation should be difficult.

Warning labels etc. should only be used when allother means of safeguarding will impair the function ofthe installation or are not cost effective.

The degree of safeguarding required should be iden-tified during the design process.

Special attentionWhen correctly applied, the FlexLink family of compo-nents are safe to use and maintain. It is, however, neces-sary for those responsible for design, installation,

operation, and maintenance of the FlexLink installation tobe aware of certain areas where special attention isrequired.

All drive units with slip clutch

Before adjusting the slip clutch, it is necessary toremove all objects from the chain to remove anyremaining chain tension.

Adjustment should be conducted in accordance withthe maintenance procedures specified.

All drive units with the exception of direct drive unitsare fitted with transmission chain covers. These cov-

ers must be fitted before unit is operated.Note: The slip clutch is not a personnel safety device, buta device to protect the conveyor equipment.

End drive units

The chain slack (catenary) of the end drive units mustbe maintained during the system lifetime.

If side plates are fitted, the chain must be shortened ifit becomes visible below the level of the side plates.

For coupled drive units, safety protection should beapplied to the connecting shaft.

Intermediate drive units

The area near the guides for the return loop of the chainshould not be accessible during conveyor operation.

Catenary drive units

The bridge area where the chain goes down into thedrive should not be accessible during conveyor opera-tion.


24/132


General safety and design considerations (continued)

Horizontal bend drive units

The drive wheel and the transmission chain should notbe accessible during the conveyor operation.

Idler units

The opening between the links when they turn round theidler roller could be a risk. Idler ends should not be acces-sible during conveyor operation wherever possible.

Wheel bends

Guarding may be required at wheel bends dependingupon location of bends and load applied to the conveyor.

Cleated chains

Any application incorporating cleated chains requirescareful safety consideration. Pinch and shear pointsare generated throughout the assembly of the incor-porated components, therefore generous guardingshould always be employed to fully protect within useroperating limitations.

There is a higher risk of product damage when usingcleated chains. Special attention must be given tooperator access in the event of product becomingtrapped or similar.

MaintenanceThe routine maintenance of FlexLink conveyors shouldalso include procedures to ensure that any guardingremains securely fastened and effective if not interlockedvia control system etc.

FlexLink components are continuously reviewed to

improve performance either by design modification ormaterial upgrade. In all these reviews user safety is ourfirst consideration.

The design review procedure as recommended underthe Machinery Directive 98/37/EEC is followed and allassociated technical data is retained at the manufac-turer s address.

Conveyor chains 43

Conveyor chainsType XS, XL, XM, XH, XK, XB

IntroductionThe conveyor chain consists of plastic links joinedtogether by means of plastic pivots and stainless steelpins. It can be delivered with or without cleats.

The chain is also available with composite chain linksbased on the standard link design, combined with a spe-cial chain top (does not include XS). The basic link has

the same technical properties as the standard link.The System XB chain base is similar to the XS XKchain bases. The top part, however, is much wider thanthe base, for efficient handling of wide products such ascardboard boxes etc., for example in the packaging andfood industries.

Plain chain (XS, XL, XM, XH, XK)The plain chain has a flat topsurface. The surface has lowfriction which allows accumu-lation of products.

XK plain chain Type A is aclosed top chain and has thesame technical properties asthe standard XK chain. It ismainly intended for use in pal-let applications.

Height of chain above beam

The following table lists theheight of chain for plain chain.Note that the A and B dimen-sions are not always thesame for plain chain as forother chain types such as cleated chain. See separatepublication 4301, "Chain guide", for more information.

Plain chain (XB)The XB chain is designed forgentle handling of bulky orsoft ready-packed productsrequiring stable support on awide chain.

The 175 mm/295 mm

wide chain features overlap-ping links that stay closedeven in the tight radius bend.This minimizes the risk of

jamming or tearing goods.

Safety (XB)

Tight chain design also minimizes the risk of fingers get-ting pinched in the chain.

Friction top chain (XL, XM, XH, XB)The friction top chain is espe-cially suitable for track config-urations with inclines up to30 , and where a standardcleated chain is unsuitable. Afriction insert moulded intothe link increases the frictionbetween goods and chain.

Always test with the spe-cific product to ensure thatthe friction is sufficient at thedesired inclination.

Chains Type XS, XL, XM, XH, XK, XB (continued)

Steel top chain (XL, XM, XH, XK)The steel top chain replacesthe standard plain chain, ifthe products conveyed arecausing excessive wear tothe standard chain. It isintended primarily for themechanical manufacturingindustry, for transport of cast-ings or machined items withsharp edges.

Based on the standard plain link, the steel top chainhas the same technical properties as the standard link.

Cleated chain (XS, XL, XM, XH, XK)Cleated chain is required forvertical or steeply inclinedconveyor tracks. Cleats areavailable in different heightsand shapes. The cleat typemust be selected to suit theshape of the goods con-veyed. High cleats arerequired for long work pieces,otherwise the ends of thework piece would rise over the top of the cleat on vertical(convex) bends.

Roller top chain (XL, XM, XH)The roller top chain is espe-cially suitable for sensitivegoods in buffering areas, andfor long buffer sections wherethe accumulating pressurecould become high with thestandard chain. The rollerson the chain top reduce thefriction between the chainand the goods, so thatscratch sensitive goods can be conveyed without beingdamaged.

Important

Note that roller top links cannot be interleaved with plainlinks or other fingered links if the conveyor includes hor-izontal bends.

Roller cleat chain (XM, XH, XB)Roller cleats are suitable forexample for cardboard boxesin slopes. They permit easytransfer from another con-veyor.

Flexible cleat chain (XL, XM)The flexible cleat chain isintended for vertical trans-port in vertical wedge con-veyors. Suitable productsinclude glass and plastic bot-tles, soda cans, and card-board boxes. Two conveyorswith flexible cleat chain fac-ing each other form the verti-cal wedge conveyor. Seefigure below.

Flexible cleat chain typeX_TE 5 D has flexible rubbercleats which can be removedfrom the chain and replacedif necessary. The chain isbest used with smaller prod-ucts, or where the gapbetween cleats must besmall.

Other chain typesIn addition to the standard types, several special-purposechain links are available. See FlexLink chain guide whichlists all chain types available. It is also possible to ordercustomer specified chains. Please contact FlexLink Sys-tems for additional information.

Tools and accessoriesSee page 54.

Ordering informationThe chain comes in 5 m lengths (XB: 3 m). Separate linkscan also be ordered. Plastic pivots and steel pins areincluded with chain and link deliveries, so they need only

be ordered for replacement purposes.1 Calculate the required length of chain. For effective

track lengths of bends, drive units etc., refer to thetables Effective track lengths in Conveyor engineer-

ing guidelines . Be sure to use the value for a two-waychain if the chain returns on the bottom of the beam.The chain must be ordered in 5 m sections (XB: 3 m).

2 If cleats are required: Determine the type and dis-tance between them. The distance should be at least1,5 times the length of the product conveyed.

The desired distance is denoted by adding a digitafter the designation suffix: If, for instance, every fifth

link is to be a Type X cleat link, then write X5; if everyeighth, then write X8, etc.

Example

XSTF 5 9 D8 is a 5 m chain section. It has type D cleats,9 mm high, on every eighth link.

Tools and accessories for chains

Plastic pivot and steel pinThe chain links are connected by means of plastic pivotsand steel pins. Pivots and pins are included with chainand link deliveries, so they need only be ordered forreplacement purposes.

Chain assembly toolA special pin insertion tool is available for use when

assembling and dismantling the chain. The tool helpswhen inserting and removing the stainless steel pin join-ing two chain links together.

Chain lubricationThe chain is lubrication-free. A new chain running on newslide rails, however, will need a few hours of running-inbefore it runs perfectly smoothly. For applications whereabsolutely smooth running is essential from the start, asilicone-based lubricant (LDSS 450) is available.

Conveyor beams 55

Conveyor beamsType XS, XL, XM, XH, XK

Aluminium beam profilesFlexLink conveyors are based on aluminium beam pro-files. Systems XS, XL, XM, XH, and XK are single profilebeams, whereas system XB beams consist of a singleprofile in the middle, with side profiles on each side, tocreate a wider conveyor.

Conveyor beam XS, XL, XMThe chain track for straightconveyor sections is deliveredas beam stock to be cut asrequired.

Conveyor beam XHThe chain track for straight

conveyor sections is deliveredas beam stock to be cut asrequired. Two conveyor beamversions are available stand-ard (sufficient in most applica-tions) and reinforced (R).

Conveyor beam XKThe chain track for straightconveyor sections is deliveredas beam stock to be cut asrequired. Conveyor beamXKCB is normally used.

Conveyor beam XKCB typeN can be used for track sec-tions where it should be possi-ble to lift the chain out of thebeam to facilitate cleaning, etc.See figure.

Conveyor beam XKCB typeN can be joined only to theordinary XKCB beam or to theplain bend XKBP.

Conveyor beam type Nmust not be used in applica-tions where the conveyorbeam has an inclination fromthe horizontal plane.

Technical specificationsPoint load F + beam weight + weight of two-way chain for10 mm deflection, see illustration:

Slide railsSlide rail products: see page 61.

Plastic slide rail is used to provide a low-friction track forthe chain. Slide rail is available in four plastic materials:HDPE, PVDF, UHMW-PE, and PA-PE, and in acid resist-ant stainless steel, see table.

HDPE slide rail is suitable for most standard applica-tions. In environments where high resistance to chemi-

cals is important, PVDF slide rail is recommended.PA-PE and UHMW-PE slide rail is best suited for highspeed applications, high accumulation loads, or wherecleanliness is important. See Considerations whenselecting slide rail on page 39.

Slide rail made of acid resistant stainless steel isavailable in 3 m straight lengths. It is intended for highwear applications. (Use PVDF slide rail in bends.)

Plastic screws or aluminium rivets are used to fix theslide rail to the beam, see table. See Anchoring the sliderail in Appendix A, page 370.

Note : When using UHMW-PE slide rails and the calcu-lated load from a product exceeds 20 N for a single chain

link, always use plastic screws every meter of the sliderail. See Considerations when selecting slide rail onpage 39.

Installation of slide rail on XKCB N: See Slide railinstallation conveyor beam XKCB N in Appendix A,page 372.

Tools and accessories (XB see next page)Installation tools for slide rail

Special tools are available for installation of the slide rail.See page 62. Also see Appendix A, page 368, whereinstallation of the slide rail is described.

T-slot cover strip

A snap-fit cover strip is available to cover the T-slots in thebeam. See page 63.Connecting strips

The beams are joined together by means of connectingstrips. Normally, the longer strips should be used whentwo lengths are available. Connecting strips are listed onpage 63.

Beam section

A beam section can be used to simplify chain installation.The beam section is open on one side, so that the chaincan be installed. After installation of the chain, the remov-able chain guides are returned and secured by means ofscrews. (See Appendix C, page 375.)

Beam spacer

The beam spacer is used to connect two conveyorbeams side to side. Assembly: cut the beam spacer tothe desired length. Connect using M8 screw and slot nut.Two holes must be drilled: one through the spacer beam(9 mm), and one in one of the beams to allow insertion ofthe screw. The diameter of the second hole depends onthe size of the screw head. See figure.

Tools and accessories overview

Ordering information (XB see next page)1 Determine the number of beam lengths/sections

required. Beams can be delivered in 3 m and 6 mlengths, and precision cut to any length up to 6 m.

2 Determine the length of slide rail required. Fourlengths of slide rail are normally required for each

length of track, if the chain returns via the bottom ofthe beam.

Note for XK : XKCB type N requires six slide raillengths.

Do not forget bends, drive units etc. The effectivetrack length of each such component is specified inthe table Effective track lengths in Conveyor engi-neering guidelines .

3 Estimate the required number of plastic screws or alu-minium rivets for the slide rail. Two screws/rivets arerequired for each separate piece of slide rail. Thescrews/rivets must be ordered separately. The quan-

tity must be specified in multiples of 50 (plasticscrews) or in multiples of 250 (rivets).

4 Determine the number of connecting strips required.Two connecting strips are required for each jointbetween straight beam sections.

The connecting strips must be ordered separately. Note!Bends, drive units, etc. are delivered with the necessaryconnecting strips.

Conveyor beams 57

Type XB

Conveyor beam XBThe chain track for straightconveyor sections consists ofa middle section similar insize to the XM beam, withseparate half-section beamsattached on the sides toobtain the desired width(182 mm/300 mm). Straightsections up to 3 m can bedelivered assembled(XB 175 version), in kit form(XB 295 version), or asunassembled parts.

Technical specifications XB

Beam deflection under load

Point load F + beam weight + weight of two-way chain for4 mm deflection (see illustration):

F = 1200 N

Tools and accessories XBThe beam sections are joined together to the desiredlength by means of four connecting strips at each joint.For easy assembly, the two middle strips should extend10 mm further out from the beam than the outer strips.Only the outer strips need to be secured at both ends.

The outer beam half-sections are attached to the mid-dle section using snap-fit aluminium clips ( XB 175 ver-sion) or aluminium spacers ( XB 295 version). A specialtool (3923518) is required for fitting the clips with preci-sion. Clips or spacers must be used minimum every 0,5m.

A special tool for the installation of slide rail(XBMR 170) is available. A snap-fit plastic or aluminiumcover strip is available to cover the T-slots in the beam.

Plastic screws or aluminium rivets are used to fix theslide rail to the beam, see table on Page 55. SeeAnchoring the slide rail in Appendix A, page 370.

Beam section XBCC 300A can be used to simplifychain installation. This 300 mm beam section can beopened on one side, so that the chain can be installed.After installation of the chain, the removable chain guidesare returned and secured by means of screws (seeAppendix C, page 375).

Ordering information1 Determine the number of beam sections required.

Straight beam sections can be delivered in assem-bled sections up to 3 m ( XB 175 version), in kit form(XB 295 version), or as unassembled parts. Order asufficient number of clip kits or spacers to allow for amaximum distance of 0,5 m between clips/spacers.

2 Determine the length of slide rail required. If XBCR 25

is used, six lengths of slide rail are normally requiredfor each length of track four on the top side and twoon the bottom side (middle section). If XBCR 25 isused in combination with XBCR _ UA, four lengths ofregular slide rail and two lengths of slide rail for theupper outer beam sections are normally required. Donot forget bends, drive units etc. The effective tracklength of each such component is specified in thetable Effective track lengths in Conveyor engineer-ing guidelines . Note that an extra length of slide rail isused in bends. See page 102

3 Estimate the required number of plastic screws for theslide rail. Two screws are required for each separate

piece of slide rail. The screws must be ordered sepa-rately. The ordered quantity must be a multiple of 50.

4 Determine the number of connecting strips required.Four connecting strips must be ordered separately foreach joint between straight beam sections. (Bends,drive units, etc. are delivered with the necessary con-necting strips.)
