System and method for controlling continuous auto-packing machine

Abstract

The invention relates to a system and a method for controlling a continuous auto-packing machine. The system comprises a rotary encoder, a position sensor, a color scale sensor, a vertical-seal drawing roller driver and a system controller; function parameters are input and stored into a memory of the system by corresponding function light touch keys of the system controller; a main motor of a packing machine runs; the system works; a vertical-seal drawing roller starts; and the speed of the vertical-seal drawing roller and the speed of the main motor are synchronous, so as to finish the operations, such as packing, paper letting-off, bag length, size and speed setting, pictorial trade mark positioning, automatic system controlling, error compensating, and the like. As a horizontal-seal roller eccentric mechanism is eliminated, the system has the advantages of reasonable mechanical structure, simple control arrangement and convenient system operation. When the bag length is different, only the corresponding length dimension needs to be reset, therefore, other structures of the packing machine are not required to be adjusted. The system is applicable for the control to the bag making, the cursor tracking and the cutting operations of the continuous auto-packing machine.

Description

technical field [0001] The invention belongs to the field of packaging machinery control, and relates to a continuous automatic packaging machine control system and a control method, which are used for the control of the continuous automatic packaging machine bag, cursor tracking and cutting process. Background technique [0002] The bag making and sealing system currently used in continuous automatic packaging machines in food, pharmaceutical, chemical, daily chemical and other industries is mainly composed of two parts, namely the longitudinal sealing mechanism and the horizontal sealing mechanism. In addition to sealing, the longitudinal sealing mechanism also takes into account the functions of pulling packaging materials and cursor positioning. Since the packaging bag length specifications of the packaging machine manufacturers are different, the packaging machine is required to meet the requirements of different bag lengths and sizes, and can be adjusted. By adjusting ...

AI Technical Summary

Problems solved by technology

In this method, when the bag length of the packaging bag is changed, the eccentricity of the eccentric wheel must be adjusted to ensure the sealing requirements of the bag making, so the adjustment is troublesome, and it needs to be adjusted every time a specification is changed.
