1.1 What is sorting System?

1.1.1 There are lots of definitions of sorting as below:

1. A group of persons or things of the same general character; a kind.

2. Character or nature: books of all sorts.

3. One that exemplifies the characteristics of or serves a similar function to another: "A large

dinner-party ... made a sort of general introduction for her to the society of the

neighborhood" (George Eliot).

4. A person; an individual: The clerk is a decent sort.

5. To separate from others: sort out the wheat from the chaff.

6. An act or instance of sorting: did a sort on the columns of data.

7. To arrange according to class, kind, or size; classify. See Synonyms at arrange.

8. To clarify by going over mentally: She tried to sort out her problems.

2.1 How we got this idea?

When we saw video of Apasara Manufacturing and Detect system on basis of pneumatics

systems.We like it and We all wanted to make a semi automatic mechanical inspection system. Our

key interest was in pneumatic systems & material handling systems. But in industries people are not

using core pneumatic system, they are using ElectroPneumatic system. So at the end we decided to

work on Pneumatic based sorting system using temperature sensor. Ultimately with help of this

project we could learn ElectroPneumatic systems as well as sensor technology. So we can say that

we learn Fluid machines as well as electrical things also.

2.2 Project Details:

First of all we have to put our machined objects on the conveyor running by motor.

Temperature sensor will sense the temperatures of objects.

According to our logic fed in microcontroller, signal will be sent to the direction control valve

via microcontroller.

At the end direction control valve will pass the pressurized air to the pneumatic actuator and

accordingly object will be removed.

In this way this system will sort machined objects according to its temperature.

2.3 How we are working on this Project?

This project is made of lots of different streams.

Things are to be done or design as below in the form of project details.

Very first we have to learn designing a motor conveyor. After that we have to design belt

with appropriate materials & dimensions. Then motor with desired rpm, torque & current capacity.

Finally we can have conveyor belt system for our temperature sorter.

Second we have to learn ElectroPneumatic system. Deciding direction control valves,

actuators, filter units, lubricator units, pressure regulator & Simulation of the system for faster

design.



Third we have to learn about temperature sensors, its characteristics, its interfacing

circuits, interfacing with solenoid valves etc.Then at the last we have to learn about the

microcontroller used in CNC. Ultimately we will program the microcontroller and according to its

program it will control the system.

2.3.1 Our Project can be divided into four parts:

1) Pneumatic Systems (Fluid Mechanics).

3.1History of sorting

Sorting system is the part of material handling systems & also part of inspection system. So

we could go through the history of material handling system.

While there is no way to determine the origin of material handling as a concept, the industry

of material handling goes hand-in-hand with commercial trade. As long as trade has been occurring,

there has been a need to somehow handle the goods being exchanged. The roots of modern material

handling begin with the industrial revolution. Skids and pallets were introduced early in the 20th

century to replace wooden boxes, crates, barrels, and kegs, which had previously been used to store

and transport goods. Before the mechanization of material handling, barrels had the advantage of

being able to be tipped on their side and rolled as a means of transport. Textile sacks had been the

primary means for storage and transport of granular products such as flour or feed. The pallet soon

replaced many of these other types of unitizing equipment and became an integral part of the material

handling industry. Corrugated containers became another monumental piece of material handling

equipment. Corrugated paper was invented in the 1850s, and around the turn of the

century, corrugated shipping containers began to replace their wooden counterparts. This new type

of container greatly reduced packaging and shipping costs by switching to more inexpensive and

lighter paper-based packaging materials.

3.3 Component Description.

3.3.1 Pneumatic Component Description.

3.3.1.1 FRL Unit

Specifications:

Medium: Compressed air

Mounting position: Vertical ± 5°

Pressure range max.: 10 Bar

Temperature nominal: -10 to 60°

Fig3.2 Frl unit

There are three types of air preparation processes.

Filtering contaminants out of the air

Regulating the air pressure level

Lubricating the air



3.3.1.2Filter:

Fig3.3

As air flows under pressure, it carries particles called contaminants. These particles will cause

damage to components throughout a pneumatic system.

3.3.1.3 Regulator

Fig3.4

A pressure regulator has two functions.



To adjust the supply pressure to a desired level

To maintain a constant air pressure

3.3.1.4 Lubricator:

Fig3.5

Pressurized air that enter the input port also enter the pilot line.

3.3.1.5 5/2 Direction Control Valve:



A solenoid valve has two main parts: the solenoid and the valve. The solenoid converts electrical

energy into mechanical energy which, in turn, opens or closes the valve mechanically. A direct

acting valve has only a small flow circuit, shown next page.

Fig3.6 Direction Control Valve

The media controlled by the solenoid valve enters the valve through the inlet port

(Part 2 in the illustration above). The media must flow through the orifice (9) before

continuing into the outlet port (3). The orifice is closed and opened by the plunger

(7).

The valve pictured above is a normally-closed solenoid valves. Normally-closed

valves use a spring (8) which presses the plunger tip against the opening of the

orifice.

The sealing material at the tip of the plunger keeps the media from entering the

orifice, until the plunger is lifted up by an electromagnetic field created by the coil.

http://www.pneumaticpart.com/solenoid-valve/solenoid-valve.html



3.3.1.6 Double Acting Pneumatic Cylinder:

Fig3.7 Double Acting Pneumatic Cylinder

General

Once actuated, compressed air enters into the tube at one end of the piston and, hence, imparts force

on the piston. Consequently, the piston becomes displaced (moved) by the compressed air expanding

in an attempt to reach atmospheric pressure.

Compressibility of gasses

One major issue engineers come across working with pneumatic cylinders has to do with the

compressibility of a gas. Many studies have been completed on how the precision of a pneumatic

cylinder can be affected as the load acting on the cylinder tries to further compress the gas used.

Under a vertical load, a case where the cylinder takes on the full load, the precision of the cylinder is

affected the most. A study at the National Cheng Kung University in Taiwan, concluded that the

accuracy is about ± 30mm, which is still within a satisfactory range but shows that the

compressibility of air has an effect on the system.

http://en.wikipedia.org/wiki/Atmospheric_pressure



Fail safe mechanisms

Pneumatic systems are often found in settings where even rare and brief system failure is

unacceptable. In such situations locks can sometimes serve as a safety mechanism in case of loss of

air supply (or its pressure falling) and, thus abate any damage arising in such a situation. Due to the

leakage of air from input or output reduces the pressure and so the desired output.

Although pneumatic cylinders will vary in appearance, size and function, they generally fall

into one of the specific categories shown below. However there are also numerous other types of

pneumatic cylinder available, many of which are designed to fulfill specific and specialized

functions.

Single-acting cylinder

Single-acting cylinders (SAC) use the pressure imparted by compressed air to create a driving force

in one direction (usually out), and a spring to return to the "home" position. More often than not, this

type of cylinder has limited extension due to the space the compressed spring takes up. Another

downside to SACs is that part of the force produced by the cylinder is lost as it tries to push against

the spring. Because of those factors, single acting cylinders are recommended for applications that

require no more than 100mm of stroke length.

Double-acting cylinders

Double-acting cylinders (DAC) uses the forces of air to move in both extends and retract strokes.

They have two ports to allow air in, one for outstroke and one for in stroke. Stroke length for this

design is not limited. However, the piston rod is more vulnerable to buckling and bending. Addition

calculations should be performed as well.

3.3.2 Electrical Component Description.

3.3.2.1 Relay circuit

A relay is an electrically operated switch. Many relays use an electromagnet to operate a switching

mechanism mechanically, but other operating principles are also used. Relays are used where it is

necessary to control a circuit by a low-power signal (with complete electrical isolation between

control and controlled circuits), or where several circuits must be controlled by one signal. The first

relays were used in long distance telegraph circuits, repeating the signal coming in from one circuit

and re-transmitting it to another. Relays were used extensively in telephone exchanges and early

computers to perform logical operations.

A type of relay that can handle the high power required to directly control an electric motor

or other loads is called a contactor. Solid-state relays control power circuits with no moving parts,

instead using a semiconductor device to perform switching. Relays with calibrated operating

characteristics and sometimes multiple operating coils are used to protect electrical circuits from

overload or faults; in modern electric power systems these functions are performed by digital

instruments still called "protective relays".

3.3.2.3Temperature Sensor LM35:

Fig3.7 Temperature Sensor

LM35 is a precision IC temperature sensor with its output proportional to the temperature

(in oC). The sensor circuitry is sealed and therefore it is not subjected to oxidation and other

processes. With LM35, temperature can be measured more accurately than with a thermistor. It

also possess low self heating and does not cause more than 0.1 oC temperature rise in still air.

The operating temperature range is from -55°C to 150°C. The output voltage varies by 10mV in

response to every oC rise/fall in ambient temperature, i.e., its scale factor is 0.01V/

oC.

3.3.2.4 Infrared senser:

An infrared sensor is an electronic device that emits and/or detects infrared radiation in order to

sense some aspect of its surroundings. Infrared sensors can measure the heat of an object, as well

as detect motion. Many of these types of sensors only measure infrared radiation, rather than

emitting it, and thus are known as passive infrared (PIR) sensors.

http://www.wisegeek.com/what-is-infrared-radiation.htm

http://www.wisegeek.com/what-is-infrared-radiation.htm



All objects emit some form of thermal radiation, usually in the infrared spectrum. This radiation

is invisible to our eyes, but can be detected by an infrared sensor that accepts and interprets it. In

a typical infrared sensor like a motion detector, radiation enters the front and reaches the sensor

itself at the center of the device. This part may be composed of more than one individual sensor,

each of them being made from pyroelectric materials, whether natural or artificial. These are

materials that generate an electrical voltage when heated or cooled.

These pyroelectric materials are integrated into a small circuit board. They are wired in such a

way so that when the sensor detects an increase in the heat of a small part of its field of view, it

will trigger the motion detector's alarm. It is very common for an infrared sensor to be integrated

into motion detectors like those used as part of a residential or commercial security system.

Most motion detectors are fitted with a special type of lens, called a Fresnel lens, on the sensor

face. A set of these lenses on a motion detector can focus light from many directions, giving the

sensor a view of the whole area. Instead of Fresnel lenses, some motion detectors are fitted with

small parabolic mirrors which serve the same purpose.

An infrared sensor can be thought of as a camera that briefly remembers how an area's infrared

radiation appears. A sudden change in one area of the field of view, especially one that moves,

will change the way electricity goes from the pyroelectric materials through the rest of the

circuit. This will trigger the motion detector to activate an alarm. If the whole field of view

http://www.wisegeek.com/what-is-a-motion-detector.htm

http://www.wisegeek.org/what-is-a-circuit-board.htm



changes temperature, this will not trigger the device. This makes it so that sudden flashes of light

and natural changes in temperature do not activate the sensor and cause false alarms.

3.3.3 Electronic Component Description:

A)3.3.1 Microcontroller Arduino

A microcontroller (sometimes abbreviated µC, uC or MCU) is a small computer on a

single integrated circuit containing a programmable input/output peripherals. Program memory

in the form of NOR FLASH or OTP ROM is also often included on chip, as well as a typically

small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to

the microprocessors used in personal computers or other general purpose applications.

Microcontrollers are used in automatically controlled products and devices, such as automobile

engine control systems, implantable medical devices, remote controls, office machines,

appliances, power tools, toys and other embedded systems. By reducing the size and cost

compared to a design that uses a separate microprocessor, memory, and input/output devices,

microcontrollers make it economical to digitally control even more devices and processes. Mixed

signal microcontrollers are common, integrating analog components needed to control non-

digital electronic systems.

Arduino is a tool for making computers that can sense and control more no. of Inputs and

outputs. It is based on a simple microcontroller board, and a development environment

for writing software for the board.

Arduino can be used to develop systems, taking inputs from a variety of switches or

sensors, and controlling a variety of lights, motors, and other physical outputs.

(analog digital input output) must be transferred to the Atmel atmega168 microcontroller.

in order to communicate with the I/O devices.

These programs are provided by Matlab developer team as additional package. The

5.1 Relay Circuit Diagram & Operation:

Automatic actuation of pneumatic cylinder requires automatic actuation of

solenoid. For that we need to write a program in the controller according to our

position step diagram. Program will be thus transferred from microcontroller to the

solenoid via a relay circuit, which ensures protection of the controller under

fluctuating current.

Fig5.1 Relay Circuit

Controller output is in the form of bit. This output is fed to the relay circuit. Relay circuit is

provided for safety of controller and switching of solenoids. Switching of the solenoids is

actually taken care by a general purpose transistor. Diode prevents reverse flow of current.



Fig 5.2 Actual Snap of Relay Circuit

When D0 is set, transistor will be forward bias enabling the flow of current through collector to

emitter. The normally open contact closes & supplies power to solenoid. Solenoid actuates pneumatic

DCV & it actuates pneumatic cylinder.

Operation:

In our project motor conveyor should run forward as well as reverse. To do so we have to use two

relays & 4 contacts as given in above figure.

When arduino will give supply to the first relay it will trigger only two forward contacts so conveyor

will run forward. When arduino will give supply to the second relay it will trigger only two reverse

contacts so conveyor will run reverse.
