Application of KEWEI Intelligent Servo in the Control System of Punch Feeder

1. Equipment overview
The automatic punch feeder is an automatic equipment used to feed the punch, which is composed of an electrical control cabinet and a feeding head. The ordinary punching machine equipped with an automatic feeder is transformed into a CNC punching machine. The whole machine tool can realize the functions of loading, automatic discharging, automatic feeding, automatic punching, and cutting of the entire sheet material. In addition, raw materials can be used to the maximum in production to improve production efficiency. At the same time, it also has the advantages of manual off-machine operation, ensuring safety, and improving working conditions. It is widely used in machinery, electrical appliances, instruments, cans, and screens. Stamping processing of nets, bottle caps, electric control cabinets, hardware and other industries.

2. Process requirements
The automatic feeder system can realize multi-stage feeding control. You only need to set the feeding length and feeding quantity of different stages on the touch screen, and the system will carry out multi-stage automatic feeding according to the set parameters. The control system not only controls the feeding part, but also controls the pressing and shearing actions of the punch. The user can turn on or turn off these functions on the touch screen according to their needs.

3. Control system The Kewei automatic feeding system is composed of the Kewei KPS intelligent servo, the Kewei servo motor, and the Kewei 7-inch touch screen. On the one hand, the system can realize the pulse fast output through the internal pulse setting function to control the servo motor for positioning movement. On the other hand, the built-in PLC function can complete the collection of input signals such as sensors and the control of output signals, and then control the pressing and shearing actions of the punch part. The entire system is extremely simple in structure, and the upper computer touch screen is easy to understand, and the user can master all its functions in the shortest time, which is convenient to use.
The control system scheme is shown in the figure below:

Four, function introduction

After starting up, enter the "operation page", the operation page can monitor the current operating conditions of the entire system, such as the current output count, number of feeding sections, feeding length, feeding speed and working mode, etc. In addition, you can also perform operations such as count reset, paragraph reset, and jog motor by pressing the button.

Five, system advantages
The control scheme of the traditional punch feeding system is composed of touch screen, PLC and ordinary servo. The servo is controlled by the PLC output pulse signal for feeding. During the processing and production process, the PLC output pulse signal is susceptible to external interference and leads to deviations in the feeding. Kewei KPS intelligent servo is a drive control product integrating servo drive technology and PLC technology. It is applied to automatic punch feeders, which fully reflects the high integration, fast response, stable operation, accurate positioning and no external interference of KPS intelligent servo. advantage. Compared with the traditional solution, KPS intelligent servo with 7-inch touch screen has a significant improvement in process integrity, system reliability, punching accuracy and feeding speed. And the installation is simpler, the cost is lower, and it can be adapted to the fast feeding requirements of high-speed punching machines on the market.

6. Summary Nowadays, the control system is becoming more and more highly integrated, and there is an increasing need for more streamlined and efficient control products in the market. The KPS intelligent servo has emerged as the times require, with high-end integrated technology and stable and fast processing performance. Accepted by the majority of users, it is in an absolute leading position in the current domestic intelligent servo market, and the automatic feeding system derived from it has also withstood the test of various sites and has been praised by users.
