Among the processes for making final products using fibers, the final process can be called a sewing process. The sewing process generally corresponds to the process that requires the most manpower in the production of textile products. The cost of sewing has gradually increased due to the recent rise in labor costs. The automation of the sewing process and the smart factory are expected to be carried out along with the fourth industrial revolution. In order to make the sewing factories smart, it is essential to apply smart sensing technology to the sewing machines. Also, sewing Process In order to grasp real-time situation, a system to monitor the status of each machine is needed. This study can be regarded as a part of technology development for automation and unmanned sewing process for final CPS(cyber-physical system) implementation. MultiNeedle Sewing Machine Repair Service Center in Chennai Three techniques have been developed in the sewing machine modification technology to assist the smarting and sewing process of the sewing machine. Three kinds of developed technology are a bobbin remaining amount detecting technique, stitch length control, and monitoring techniques. As a result of step-by-step technology development to realize CPS finally, it is a partial technology development of automation through some modification of sewing machine. The developed technology is expected to be used as a technology for future smart sewing automation plant construction.
The utilization of proper power has to be confirmed without wastage. That is why the integration of VFD topology along with the conventional clutch motor is important. In VFD topology, grid AC power is going to be converted to DC which can be inverted to AC power by a designed single phase inverter [8]. This VFD based inverter will be added to the clutch motor. It will help to soft start the motor and control its speed with a speed tuner. By this modified technique, the sewing machine will run more accurately with a controlled speed and soft starting.
By varying the frequency, the speed of the motor can be varied (Fig.5). Therefore, to keep torque of the motor constant throughout the speed range a VFD is required to
ensure it by varying the voltage and frequency by the same ratio. VFD based inverter provides the autonomous system to keep the torque even in voltage fluctuation conditions
The industrial manufacturing of sewn products has always been one of the critical processes of the textile chain concerning quality assurance. Assuring the appropriate set-up and operation of all the machines, and thus the final seam quality, is a very complex task. Traditionally, this task is accomplished by empirical methods, with machine setting and quality control relying on the skills of operators and technicians. In this work, an approach to a more knowledge-based and integrated process planning and control is presented. A system was developed to measure and analyze the most important mechanical effects occurring during high-speed sewing. A general overview over this development is given in this paper.Gemsy Sewing Machine Repair Service Center in Chennai
