Decoration possibilities

oval, rectangular, square and polygon containers. It is capable of handling low-cost label papers as well as a wide range of film labels. Reverse-printed transparent film labels are processed with the same precision

as coloured film labels. As part of krones’ modular component system the Contiroll can also be equipped with additional labelling stations. With the Contiroll, creative labelling is limited only by imagination.

System advantages: Large capacity label reels minimise

the operator workload Precise label placement gua-

ranteed by positive container positioning via centring bells and

centring plates Low glue consumption Short changeover times in case of

container or label changes High flexibility thanks to the

modular design Retrofitting possible even after

many years

Wrap-around labelling with hotmelt or cold glue

Special requirements demand special solutions, especially with reel-fed labelling. The Contiroll was designed as a rotary-type labelling machine and is equipped with an extremely precise labelling station, which cuts the labels and applies them to the container. A computer-controlled feed roller and rotating cutters provide a clean and accurate cut. Depending on the label material, hotmelt or cold glue can be used as adhesive.

guarding

A variety of machine sizes and versions enable the Contiroll to handle outputs ranging from 3,000 to 72,000 containers per hour. The machine was designed ergonomi-cally, is easy to operate and maintain. More than one thousand machines installed worldwide are proof of the reliability of this labelling system.

Principle of operation

The Contiroll is a continuous-motion machine that automatically adjusts to the inflow and outflow of con-tainers. Containers arriving on the infeed conveyor are taken up by the infeed worm, spaced to pitch so that they can then be taken up by the infeed starwheel and transferred to the container table. The container rotation begins when they are posi-tioned between container plates and centring bells. The speed of the feed roller is adju-sted to the required label length, ensuring continuous web tension. A standard threading unit ensures optimal film feed. Computer and servomotor controls guarantee label cut-off at the right position while a rotating cutter drum equipped with a separate heating unit provides an exact cut.Two narrow strips of hotmelt, applied by a heated glue roller to the leading and trailing edges, keep glue con-sumption to a minimum. The hotmelt strip applied to the leading label edge ensures a precise and positive trans-fer onto the container. As the contai-ner is rotated during label transfer, labels are applied smoothly and tightly. The hotmelt strip at the trail-ing edge ensures a positive bond.

Gluing

Leading and trailing edge gluing with hotmeltThis standard Contiroll gluing method minimises glue consumption as only a narrow strip of glue is applied to the leading and trailing edges. A large glue bowl ensures an ample glue supply.

Full surface gluing with cold glueFor labelling paper labels full-surface gluing with cold glue has proven its efficiency. Labels can be applied to the containers with or without over-lap.

The labelling station of the Contiroll is controlled by a servomotor. It incor-porates a label feed roller with cut-control, cutting unit, gluing station and a vacuum-assisted gripper cylin-der for label transfer. Large-capacity label reels minimise the operator workload significantly.

for round containersThe Contiroll is equipped with the same bottle table in spoked-wheel design that has proven its effec-tiveness on all other KRONES rotary-type labellers. Depending on the requirements, up to 32 container plates can be installed. When round containers are to be processed, the plates are driven by a servomotor via toothed belts. In case of container diameter changes the speed of the belt can easily be adjusted via a touch-screen. The bottle plates are designed to fit the container base; when a new container is to be pro-cessed the plates can be exchanged without tools.

for special-shaped containersIn addition to exact centring, the labelling of special-shaped containers demands container-specific control of the centring plate rotation to guarantee proper label placement. To ensure absolute precision, bottle plates with turnstiles and exchan-geable cam segments have been employed.

for special decorationsFor special labelling processes the containers have to be aligned e.g. with the can seam or glass seal to provide accurate label positioning. KRONES has developed a container table especially for these decorations. The individual bottle plates are rotated by a computer-controlled servomotor. The containers are pho-toelectrically positioned and placed at the correct labelling position by additional rotation.

Operation and installation

OperationA large, high-contrast colour display with touch-screen enables easy and convenient operation. During opera-tion, the current production data such as container and label type, machine speed and operating hours, is con-stantly displayed and can easily trans-mitted via an interface to the line data storage system (LDS) or a prin-ter. All malfunctions are displayed as plain text graph in the selected lan-guage. Access to important produc-tion settings is protected by a code and only permitted to authorised per-sonnel.The labelling station is operated via an additional LC display (LCT 3) with clearly structured keyboard. All sett-ings and functions can easily be retrieved or changed.

Reel exchange and changeover

9

Manual splicing at reel changeoverWhen changing label reels, the operator joins the end of the first reel to the beginning of the new reel, thus eliminating the need to thread the label web into the machine at each changeover. A cutting table is mounted at the labelling station to facilitate this task.

Automatic splicing at reel change overWith an additional unit the reel changeover can be effec-ted fully automatically. The end of the first reel is spliced to the beginning of a new reel without a machine stop.

ChangeoverThe Contiroll can easily be changed over to different con-tainers or label types. First the new type is selected via the touch-screen. When a label is to be processed for the first time all labelling parameters can be programmed and stored in the menu-assisted LCT 3.In case of labelling height changes the entire labelling station can be adjusted vertically and a slide enables hori-zontal adjustment in case of container diameter changes. The station is adjusted via a crank equipped with a digital counter to enable precise repetition of all settings.

Thanks to a patented system with indexed stops, contai-ner guide rails can also be quickly adjusted with relation to the infeed worm to accommodate different container diameters. All components of a set of handling parts are coded with colours and numbers; the quick-releases for the starwheels and centre guides are captive-type. The machine is electronically height-adjustable and locked automatically. Centring bells and container plates are equipped with single-hand fasteners. As a result, change-over times are reduced significantly.

StabilisationSoft containers can be stabilised with compressed air from specially desi-gned centring bells before filling.

The krones Contiroll can additio-nally be equipped for special label-ling requirements. This additional equipment for the Contiroll is as indi-vidual as the customer‘s decorations.

Clamping starwheelClamping starwheels can be used as infeed and discharge starwheels with major advantages. A centre guide assembly is not required and the star-wheels do not have to be exchanged unless the container diameters differ by more than 20 mm. Clamping star-wheels enable the rejection of con-tainers that were rejected during the automatic label inspection.

Shrink-fittingShrink-sleeves, which are to be applied to the round or recessed sec-tions of the container, can be shrunk to fit the container contour by a con-trolled hot-air fan. The containers are rotated and heated in a shrinking carousel at machine discharge or in a shrinking station at the conveyor.

Consult our product specialists to ensure that the machine can be perfectly desig-ned to meet your labelling requirements and operate even more economically.

Labelling station for self-adhesive labelsThanks to the krones modular com-ponents system the Contiroll can additionally be equipped with an AUTOCOL label applicator for self-adhesive labels. Labels for tamper-evident sealing or similar purposes can be accurately placed.

krones GarantomatShrink-sleeves can be applied by a Garantomat as tamper-evident seals directly from the reel. This system can be installed as an additional station above the infeed or discharge of the Contiroll.

Back-up pressure reductionFor processing special-shaped contai-ners and unstable plastic containers a back-up pressure reduction station and a disengageable worm can be installed at machine infeed. This gua-rantees smooth feed of the contai-ners to the labeller.

Inspection with the krones CheckmatFaulty labelled containers can be pre-vented from entering the product flow by installing a krones Checkmat for photoelectric label inspection. This module also checks the fill level and container closures. Faulty contai-ners can easily be rejected via a retai-ning starwheel, clamping starwheel or a pusher.
