Objective
An assembly cell was developed - based on a CNC sewing machine with a basic system and integrated control system - which can easily be coupled to different jigs to process various sewing sequences. This is the first prototype automatic subassembly machine in the world.
Two patent applications have been made as a result of this project.
THE SUBJECT MATTER OF THE PROJECT IS THE DEVELOPMENT OF AN ASSEMBLY CELL IN WHICH PARTS TO BE SEWN, PREFABRICATED OR SEMI-FABRICATED ARE TRANSPORTED TO THE WORK SYSTEM AND PROCESSED FULLY AUTOMATICALLY IN A SEQUENCE OF WORK OPERATIONS.
THE TECHNICAL PROBLEM AREAS OF HANDLING AND PROCESSING OF MATERIAL DURING ASSEMBLY SHALL BE TACKLED BY LINKING WORKPIECE GUIDING AND TOOL GUIDING.
ALL NECESSARY PART ELEMENTS ARE MANUALLY FED INTO A FLEXIBLE JIG UNIT WHICH POSITIONS AND HOLDS THE PART DURING VARIOUS WORK OPERATIONS.
THE INDIVIDUAL PARTS POSITIONED BY THE JIG SYSTEM ARE TRANSPORTED TO AN AUTOMATIC PROCESSING SYSTEM WHICH PRODUCES THE DESIRED SEAM BY MEANS OF A SEWING SYSTEM MOVABLE IN THE X/Y PLANE. THIS INITIAL SOLUTION APPEARS TO BE PROMISING, BECAUSE A GREAT MAJORITY OF SEWING TASKS CAN BE PROCESSED IN TWO DIMENSIONS.
THE ASSEMBLY CELL IS DESIGNED SO THAT A BASIC SYSTEM IS SUITED TO HOLD VARIOUS JIG SYSTEMS.
IN ADDITION TO THE ACHIEVABLE PERFORMANCE INCREASES, THROUGHOUT TIME WOULD BE SIGNIFICANTLY DECREASED, WHICH MEANS BOTH IMPROVED DELIVERY DATES AND MORE FAVORABLE CONDITIONS FOR URGENT ORDERS, FOR EXAMPLE.
