Sealing and cutting tracking control system and control method for continuous automatic packaging machine

Abstract

The invention discloses a sealing and cutting tracking control system for a continuous automatic packaging machine. The sealing and cutting tracking control system comprises a PLC controller, a proximity switch, a photoelectric switch, a longitudinal sealing driver and a horizontal sealing driver, wherein the proximity switch and the photoelectric switch are unidirectionally connected to the PLC controller; and the longitudinal sealing driver is unidirectionally connected with a longitudinal sealing motor. A sealing and cutting tracking control method for the continuous automatic packaging machine comprises the steps of selecting a cursor tracking mode, comparing a received photoelectric switch signal with a sealing position signal and a proximity switch signal, then comparing the photoelectric switch signal with a cutting cursor position, if the two are the same, continuing to execute a program according to original parameters by the controller, if the two are different, calculating the error, correcting by adjusting the cutting cursor position, and executing the program according to new parameters by the controller, until the speed of a paper feeding wheel meets the needed requirements. According to the sealing and cutting tracking control system and the sealing and cutting tracking control method disclosed by the invention, a horizontal sealing eccentric wheel mechanism of the packaging machine is omitted, the system is convenient to operate, and when the lengths of bags to be made are different, only corresponding length sizes need to be reset in the system.

Description

technical field [0001] The invention relates to the field of packaging machine control, in particular to a sealing and cutting tracking control system and control method for a continuous automatic packaging machine. Background technique [0002] In the current food production, the feeding method of automatic packaging machine, labeling machine, packaging material, trademark or other packaging material cutting is mainly continuous feeding. In actual operation, various packaging sizes, trademark patterns, etc. are different. In the feeding process of packaging materials or trademark cutting, it is usually necessary to adjust the horizontal sealing eccentric wheel of the packaging machine first, so that the speed of the horizontal sealing wheel is consistent with the linear speed of the vertical sealing wheel, which will also cause the pulling of the packaging material. Therefore, in actual operation, the mechanical operation is complicated, the adjustment is difficult, the tr...

In the feeding process of packaging materials or trademark cutting, it is usually necessary to adjust the horizontal sealing eccentric wheel of the packaging machine first, so that the speed of the horizontal sealing wheel is consistent with the linear speed of the vertical sealing wheel, which will also cause the pulling of the packaging material. Therefore, in actual operation, the mechanical operation is complicated, the adjustment is difficult, the tracking response is slow, the packaging material is cut off, the size error is large, and the trademark pattern is offset, resulting in a high scrap rate, low labor efficiency, and poor packaging appearance.
