Cloth Guider Control System
Chinthaka A.K.08/8554MSc in Electronics and Automation 2008
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
Cloth Guider Operation
Cloth Guider Operation Cont..
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
Examples
Some Specifications
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
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
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
My Work
• To Provide – low cost solution– reliable product
