Application of time servo system in cigarette packaging machinery

1. Project introduction

this project provides our company with a control system for the cigarette packaging machinery of a company in Tianjin. This model of cigarette packaging machine is used for the new type packaging of cigarette hard box packets. It breaks the traditional flip type and adopts the extraction method to make the smoke offering more civilized. The standard cigarettes are arranged in two rows with ten cigarettes in each row. The specification and quantity of cigarettes can be changed arbitrarily according to user requirements, such as five, eight, ten, twelve, sixteen, etc. The unit adopts PLC programmable controller and man-machine interface graphic display for fault analysis and maintenance

the purpose of the project is to realize the linkage of two cigarette box packaging machines, carry out the packaging production of special-shaped cigarette boxes, and increase the packaging speed from the original single equipment speed of 120 packets/min to 150 packets/min after linkage

2. Solution

the text prompt displayed through the human-computer interface (HMI) is only operated in the field of die special steel materials. It makes full use of the simple PLC integrated in the servo controller to realize the coordinated linkage between the conveyor belt and the propulsion mechanism; Under the inching control mode, the conveyor belt and the propulsion mechanism can be inched separately; In the linkage control mode, the conveyor belt and the propulsion mechanism need to find the starting position of the linkage respectively; After finding the starting position, the slave sends the arrival signal to the host; After receiving the arrival signal from the slave, the host starts to complete the high-speed or low-speed synchronous linkage action according to the user's instructions; During the synchronous linkage control movement, the user can send a stop signal to terminate the synchronous linkage control; When the 1.5 load exceeds 2% (5)% of the maximum value after the stop signal is released, the synchronous linkage control action can be continued. The encoder installed on the motor can provide feedback information for the AC servo control system

software plays a very important role in realizing various functions of the system. We must pay attention to the model. The software part of the servo control system is divided into the application program of the driving machine and the application program of the driven machine

(1) hardware configuration

(2) software programming

3. Summary

the above solutions realize the coordination of the cooperative actions of all working parts of cigarette packaging machinery and the control performance they should have. The servo controller of time Technology Co., Ltd. is used to share the control task of PLC and replace the imported servo execution unit, which reduces the cost and obtains the effect of technical innovation
