Problems solved by technology

[0004] However, the above-mentioned control system has a certain error through the color mark detection and recording time, which affects the alignment accuracy of the cutter and the color mark; through the speed compensation of the film pulling axis, there is error accumulation, which cannot achieve precise position control
On the other hand, with the improvement of equipment technology and speed, the use of dedicated controllers does not have user-programmable functions, while the current general-purpose pulse output PLC (Programmable Logic Controller, Programmable Logic Controller) can realize position and speed Control, but position and speed compensation cannot be performed in real time during operation

Embodiment 1

[0052] The embodiment of the present invention provides a packaging film shearing control system, see figure 1, the system includes a film pulling shaft 1, a cutter shaft 2, a control device 3, and a color mark sensor 4 arranged on the running path of the packaging film 6 and located upstream of the film pulling shaft 1; the control device 3 includes a compensation calculation unit 31 and The imaginary shaft 32, wherein the imaginary shaft 32 forms a cam engagement relationship with the film pulling shaft 1 and the cutter shaft 2.

[0053] The color mark sensor 4 is used to send a detection signal every time a color mark 5 on the packaging film 6 is detected;

[0054] The compensation calculation unit 31 is used to calculate an adjustment amount according to the virtual axis position corresponding to the detection signal, and the adjustment amount is used to adjust the operation of the film pulling axis 1 .

[0055] It should be noted that the film pulling shaft is used to pu...

Embodiment 2

[0082] The embodiment of the present invention provides a method for controlling the shearing of the packaging film by using the packaging film shearing control system in the above embodiment, see Figure 5 , the packaging film shearing control method comprises:

[0083] S1. The color mark sensor sends a detection signal to the control device every time a color mark on the packaging film is detected; the color mark sensor is arranged on the running path of the packaging film and located upstream of the film pulling axis;

[0084] S2. The control device calculates an adjustment amount according to the position of the virtual axis corresponding to the detection signal, and adjusts the operation of the film-drawing shaft according to the adjustment amount; the film-drawing shaft, the cutter shaft and the virtual shaft form a cam engagement relationship.

[0085] In a preferred embodiment, the control device calculates the adjustment amount according to the virtual axis position c...

Abstract

The invention discloses a packaging film shearing control system. The packaging film shearing control system comprises a film drawing shaft, a cutter shaft, a control device and a color mark sensor which is arranged on a packaging film operating path and is positioned at the upstream of the film drawing shaft, wherein the control device comprises a compensating calculating unit and a virtual axis; the virtual axis forms a cam engagement relationship with the film drawing shaft and the cutter shaft; the color mark sensor is used for sending a detecting signal every time a color mark is detected on a packaging film; and the compensating calculating unit is used for calculating regulating amount according to the virtual axis position corresponding to the detecting signal, and the regulating amount is used for regulating operation of the film drawing shaft. Besides, the invention further discloses a packaging film shearing control method. The packaging film shearing control system can be used for realizing precise control on position of the color marker, and effectively improves tracking accuracy of the color marker.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a packaging film cutting control system and method. Background technique [0002] In the food packaging (vertical packaging or pillow packaging) equipment control system, the color mark on the packaging film moves forward continuously with the traction of the film pulling shaft, and the cutter mechanism follows the packaging film to cut off. The action of each cycle needs to be aligned with the color mark. [0003] Existing packaging equipment generally uses a special control system, which detects the arrival of the color mark signal through the sensor, calculates the time difference between the two color marks, and compares it with the time value between the two color marks at the theoretical speed. Adjust the speed of the film pulling axis to achieve the alignment of the cutter and the color mark. [0004] However, the above-mentioned control system detects and records time...
