Description

A controller and a multi-station material conveying system using the controller

technical field

The utility model relates to the technical field of automatic control equipment, in particular to a controller and a multi-station material transmission system using the controller. The controller is especially suitable for the control of the multi-station material transmission system.

Background technique

Traditional processing of stretched products requires a set of molds for each process, which are installed on different punching machines in sequence, and can be completed by stamping one by one. Each process in this process is mostly completed by manual operation. Because of its many processes, many molds, equipment and operators, the processing is complicated, the processing cost is high, and the processing accuracy is low. And many parts of the above-mentioned process need manual operation, so that the efficiency of production is low, the safety is poor, and the product quality is poor.

A multi-station material transfer system is composed of a multi-manipulator platform and a punching machine, which realizes the traditional five processes of feeding, stretching, reverse stretching, punching, and blanking on one piece of equipment. However, most of the existing multi-station material transfer system controllers have the following problems:

(1) Inconvenient operation. The main performance is that the operation panel of the existing controller is not centralized, the working mode selection key switch of the punch press, the manual/pedal switch of the punch press, and the mold adjustment switch of the punch press are respectively located on different operation panels, which is not conducive to the operation of the operator; There are two emergency stop switches, and the function definitions of each emergency stop switch are different. In an emergency, only the stop of the punch press or the stop of the manipulator cannot achieve a real emergency stop, which may cause an accident and cause huge losses. ; The existing controller does not consider the processing measures of one or more manipulator workpieces. Once these situations occur, manual intervention is required, and the working state of the manipulator needs to be adjusted again.

(2) Inconvenient management. The main manifestations are: the on-site environment is very complicated, iron filings and dust are easy to be generated, and the sensor is very sensitive to these, the sensor may send wrong information to the controller, causing the equipment to malfunction, resulting in serious consequences of the punching machine smashing the manipulator. The controller does not propose specific prevention and solutions to this problem, nor does it have the ability of intelligent fault diagnosis.

(3) Inconvenient maintenance. The main performance is that because this kind of controller is designed for a fixed control object, there may be a surplus of control input and output points in some functions, but its reserved function points are also targeted, which is not convenient for universal expansion , so that it cannot meet the needs of subsequent function improvement and optimization; on the other hand, since all the wiring of the controller is directly electrically connected to the components, when the components of the controller are damaged and need to be replaced, the wiring must be dismantled and rewired.

(4) The cost is high. The main performance is that the volume of the controller is too large, the controller is mainly based on the programmable controller, and the cost is high; the control program is mainly written according to the process sequence, rather than embedded simple and clear modular programming, once a fault occurs or the manipulator task changes , you need professionals to rewrite the program, and the cost is high.
