The sewing performance of high-speed sewing machine determines the performance and quality of the sewing machine, and the sewing performance also is the core technology of sewing machine. In this paper, the Virtual Prototyping of the ZJ9700MF-RS sewing machine has been established and the simulation, analysis and redesign method has been brought up to check the sewing performance. So the sewing performance of the ZJ9700MF-RS has been greatly improved. Juki Sewing Machine Repair Service Center in Chennai
The developed measurement system is based on a Singer 882 overedge machine configured to produce the three-thread stitch type 504. Several sensors measuring the relevant process parameters have been applied to the machine. The sensors’
signals are conditioned by custom-developed hardware and are then connected to a data acquisition board plugged to the PC. A software package developed in LabView acquires, stores, displays and analyses the signals .
The test rig measures sewing process variables related to three different sub-functions of the machine: Needle penetration, fabric feeding and thread interlacing or stitch formation. The pick-up of needle penetration forces is achieved by a commercial piezoelectric sensor (Kistler) that is inserted into the needle-bar
To assess the fabric feeding behavior, a piezoelectric sensor was applied to the presser-foot bar as shown in Fig. 2. This sensor measures the dynamic forces on the presser-foot bar and the spring. Additionally, an LVDT has been incorporated to indicate vertical displacement of the presser-foot HSW Sewing Machine Repair Service Center in Chennai
