AUTOMATION OF DRAW FRAME MACHINE USING B&R PLC

Prepared By: Prof. Sandeep J. Rajput Assist. Prof., EC Dept.HCET,Sidhpur.

INTRODUCTION• This presentation is about Automation of Draw Frame Machine using B&R PLC.

• The machine which makes the strong sliver by twisting the number of thin cotton threads feeds from the cans of feed creel is called Draw Frame machine.

• This machine is a substitution of the conventional draw frame machine to reduce the cost.

• The Yarn material produced by conventional draw frame is of higher cost which all the customers can’t afford.

• In order to reduce the cost of the fabric material to satisfy the customers in cost with almost same quality the machine is used.

• This new approach has lower cost because it uses less component compare to the conventional draw frame machine .

• Main aim of is approach to add Indian customer specific features & reduce the cost of TMS-2 system and NOM3 relay module which used in control panel by replacing B&R PLC.

MODES OF OPERATION

Working mode• In working mode the machine does all the routine work for which it was

programmed . As the inputs are provided to the PLC the output is taken from it. There are basically 16 inputs & 16 outputs provided in the PLC. If

more are needed than we can also use the expansion module.• In this mode there are sensors which sense the inputs and provide them to

the PLC through which we can get the output. There are a total of nine sensors for doing the work.

• The basic function of the machine is to count, even & uncurl the raw slivers that are provided to the machine. The input slivers are provided to it from the carding machine which is used to take the dust out from the cotton.

• Multiple number of slivers are provided to the machine through the feed crill. All of these slivers are than compressed into one sliver by the drawing process. After this the slivers are carried out where they are stored in the

bucket in the form of output.

MODES OF OPERATIONService mode• Within the scope of servicing, the current condition & the functionality of

components are assessed. Whatever maintenance & repair work is necessary is determined from this condition.

• In this operating mode we can select & test individual components. In some cases additional information is seen, such as rotary speeds, connections or the corresponding sensors. We can activate the service mode through the B&R PLC

• Now for selecting the component to test we can select any of it by pressing the enter button on the PLC. The components which we can test are Motors M003, M004, M115, M120, and M130. Valves Y1, Y3/Y6, Y5, Y6, Y571. Sensors A460…A468, B431, B432, B433, B436, S110, S132, S230, S240, S450. L.E.D. RED, YELLOW, GREEN.

• All the defective components after the service mode are to be replaced by the new ones. The other components which are up to date should be cleaned perfectly. Then the machine should be fully assembled back as it was before. We can manually or automatically service the machine through the service mode.

SENSOR TO I/P INTERFACING

APPLICATION• Machine TD02 has two mode of programming Working mode and Service

mode in working mode machine automatically sense the drive position and material status and these information is given to the PLC and according to the input condition and machine working PLC operate motors, drives and valves when in Service mode there are two mode Manual mode and Auto mode.

• In Manual mode we have to independently select each and every motor, drive, sensor, valve and lamp start them and stop them after noting the information about whether it working properly or not. If not then maintenance is require for the machine.

• In Auto mode machine Automatically select each and every motor ,drive,sensor,valve and lamp start them and stop them to note the information about whether it work properly or not. If maintenance is require then go to maintenance mode of machine.

• We here replace microcomputer system and NOM3 module from the Control panel of the TD02 with the B&R PLC and program it to work same as microcomputer system and NOM3 module to save cost of up to 1.25 lakh. Rs.
