  1. Cloth Guider Control System Chinthaka A.K. 08/8554 MSc in Electronics and Automation 2008

  2. Cloth Guider • Cloth Guiders are quite effective in accurately correcting the Zig-Zag movement of running web (fabric, leather, film) in stretching and removing the wrinkles • Cloth Guiders are used in Textile Industry almost all stages of production • Winding • Rewinding • Cloth processing • Printing • Dyeing • Bleaching • Printing inspection • Batching

  3. Cloth Guider Operation

  4. Cloth Guider Operation Cont..

  5. Types • Different Cloth Guider Types are • Mechanical Cloth Guider • Cheapest • Has many moving parts • Require frequent service & replacement • Pneumatic Cloth Guiders • Pneumatic cloth guider requires only normal compressed air with little maintenance cost. • Can be used on chemicals, wet conditions • No chance of electrical shock • Electrical Cloth Guiders < < My Project Focus • Electrical Cloth Guiders are working on 55/65 volts D.C supplied to its solenoid

  6. Examples

  7. Some Specifications

  8. Electrical Cloth Guider Control System • Sensors • IR sensors • LDR • Photo Diodes or Photo Transistors • Actuators • Motor or Double Acting Cylinder • Controller • Two relays are operated according to the sensory inputs

  9. Business Problem - TextPro Garment Specific • Mechanical Problem • Fork Type IR Sensors had lesser length • So frequent out of order in sensing • Electrical Problem • Frequent replacement of electronic control system part is required due to device failures • Less Reliable in continuous run

  10. Why TextPro Expects This • Device Replacement Cost • Rs. 1,15,000 per device • No place to buy this device in local market • Require to import each device from India

  11. My Work • To Provide • low cost solution • reliable product

  12. Sensor Side Logic Design

  13. TL084 Based Hysteresis Control Part

  14. Final Design

  15. PCB Design

  16. Circuit Implementation

  17. Circuit Mounted on Enclosure

  18. Modes of Operations • Manual • Auto

  19. System Before bring to TextPro
