Automatic capping machine is to transport the bottle cap to the bottle mouth through automatic transportation, and automatically tighten the bottle cap through intelligent control of mechanical operation. The equipment replaces the traditional artificial capping, greatly improve the production efficiency, and the equipment is dexterity and convenient, the capping speed is fast, the product qualified rate is high. The device is widely used in the market for capping different bottle types in food, pharmaceutical, cosmetic, lubricating oil and pesticide industries.
Automatic capping machine is currently used by most of the control system scheme PLC+HMI. Automatic capping machine is mainly used to complete the feeding, taking the cap, straightening the pipe into the bottle mouth, prescrewing, tightening and so on. According to the operation and process requirements of the equipment, so the program includes hardware design and software design. Hardware design includes hardware configuration, mechanical structure and electrical control.
The technological process of automatic capping machine mainly includes four parts: transport mechanism, positioning mechanism and prespinning mechanism. The action of the four parts of the tightening mechanism is an action cycle; According to the sensor to PLC signal to determine the position of the cap and the bottle body, so as to implement the take and put the screw action, and finally tighten the transport out.
Automatic capping machine equipment needs to use 3 servomotor, so it involves the pulse output parameters, in the PLC program to use special parameter setting instructions through the field debugging, automatic capping machine capping efficiency can reach more than 20 per minute capping, and there are 3 different size types of cover selection, after a period of operation, the equipment is stable, low failure rate. It is concluded that the PLC and touch screen with high cost performance have been well applied in the automatic capping machine.
