The synchronous control system between the push claw device and the center box device and the automatic machine in the capsule machine

Abstract

The invention relates to a synchronous control system for a push claw device, a center box device and an automatic machine in a capsule machine. The output terminal of the main control unit is connected with a main motor control circuit, and the main motor drives the automatic machine to run through a transmission device; the synchronous control unit passes a coding The speed data of the main motor is collected by the controller, the synchronous control unit controls the claw motor and the center box motor respectively through two servo drivers, and the main control unit communicates with the synchronous control unit; the method is: according to the set parameters, the synchronous control unit generates The cam table; the synchronous control unit reads the encoder data; if the automatic machine driven by the main motor is in place, the cam table is started, and the encoder data is cleared; the claw device operates synchronously, and the center box device operates synchronously; after the synchronous operation, it returns to Read encoder data step. The invention improves the asynchronous and easy-to-collision faults existing in the original production line, reduces the mechanical damage caused by the collision, ensures the normal operation of production, and reduces the maintenance cost.

Description

technical field

[0001] The invention relates to a control technology of a capsule machine, specifically a synchronous control system for a push claw device, a center box device and an automatic machine in a capsule machine. Background technique

[0002] At present, each movement unit of the capsule production line operates independently. Each movement unit is either input by an external signal or identified by the internal code of the PLC, and the corresponding parameters are input by personnel with certain professional skills, so that each movement unit can be effectively integrated into a production line. , to produce capsules. Since each operating unit is relatively independent, it is inevitable that operating unit failures will occur during the long-term production process. For example, the push claw device, the center box device and the automatic machine are three independent operating units, and control often occurs during the short-range operation of the entire system...
