FLEXIBLE SEWING CELL

Objective


A working prototype has been developed to perform the operation of setting pockets and fronts in shirts. The prototype consists of a feeding module (including front pickup and separation device and pocket feeder), a recognition and positioning module and a sewing module.
THE GENERAL OBJECTIVE OF THE PROJECT IS THE DEVELOPMENT OF AN AUTOMATIC SEWING CELL: MORE SPECIFICALLY THE END GOAL IS A WORKING PROTOTYPE INCORPORATING THE FOLLOWING SUB-SYSTEMS COMPLETELY INTEGRATED AND MEETING THE FOLLOWING SPECIFICATIONS.

THE SUB-SYSTEMS TO BE DEVELOPED ARE:
A. PICK-UP AND SEPARATION DEVICE FOR FLEXIBLE MATERIAL ABLE TO SEPARATE ONE PLY FROM A STACK OF THEM. THIS DEVICE MUST BE ABLE TO TURN MATERIAL UPSIDE DOWN.B. VISION SYSTEM TO IDENTIFY SHAPES, POSITION, ORIENTATION OF PARTS TO GATHER INFORMATION AND CAPABLE OF WORKING WITH THE PICK-UP DEVICE TO MATCH TWO PARTS AND WITH THE SEWING STATION TO SEW ACCORDING TO THE RECOGNISED SHAPE.C. A SEWING SUB-SYSTEM ABLE TO GUIDE THE PART TO BE SEWN UNDER THE SEWING HEAD ACCORDING TO THE RECOGNISED SHAPE.

THE INTEGRATED CELL MUST MEET THE FOLLOWING SPECIFICATIONS:
- EACH SUB-SYSTEM MUST HAVE ITS OWN CONTROLLER.
- THE WHOLE CELL MUST HAVE A CENTRALISED CONTROL.
- THE COMMUNICATION PROTOCOL MUST BE WELL SPECIFIED SO THAT THE DIFFERENT COMPONENTS SHALL WORK TOGETHER.
- THE OVERALL RELIABILITY MUST BE HIGHER THAN 99 %.

THE SYSTEM IS TO BE USED FOR MACHINING PARTS SUCH AS CUFFS AND COLLARS.
THIS PROJECT IS TO GATHER THE NECESSARY KNOW-HOW IN FLEXIBLE MATERIAL HANDLING TO PERMIT SUBSEQUENT APPLICATION TO OTHER KINDS OF FLAT SEAMS AND OTHER OPERATIONS. FOR EXAMPLE, A CELL WITH THE ABOVE SPECIFICATIONS WILL BE CAPABLE OF MATCHING THE FIRST PART OF A COLLAR AND ITS LINING TO ALLOW FOR SUBSEQUENT FUSING; IT WILL BE ABLE TO MATCH THE SECOND PART OF THE COLLAR TO THE FUSED ASSEMBLY AND, TO SEW THE FIRST SEAM; THE SAME CELL COMPONENTS CAN BE USED TO FEED THE IRONED COLLAR TO AN IMAGE RECOGNITION STATION AHEAD OF THE SEWING STATION AND PERFORM THE FACING SEAM.

SO THE CELL DESIGN MUST BE MODULAR IN ORDER TO ALLOW:
- TO MAKE A SINGLE OPERATION OR GROUP OF OPERATIONS IN A COMPLETE PROCESS.- ITS SUBSEQUENT EXTENSION TO COVER THE WHOLE ASSEMBLY PROCESS AS EXPLAINED ABOVE.
