Embodiment Construction
[0047] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0048] like figure 1 and figure 2 As shown, the first aspect of the present invention provides a control method for a straw packaging machine, comprising the following steps:
[0049]Step 1. Calculate the feed length of each control cycle according to the preset S-shaped speed curve to control the smooth operation of the spindle 8;
[0050] Specifically, the preset S-shaped speed curve is controlled by the spindle motion control module 5, and the feed length x of the spindle 8 in each control cycle is calculated through the S-shaped speed curve, wherein the feed lengths x are not the same; at the same time , in the case that the mechanical part is not loose and slipping, the feed length x is directly fed back to the in...

The invention provides a control method and system of a straw packaging machine and a computer readable storage medium. The control method comprises the steps of calculating the feeding length of eachcontrol period according to a preset S-shaped speed curve so as to control a main shaft to operate; calculating a following angle of a slave shaft moving along with the main shaft according to each feeding length, and controlling the slave shaft to synchronously operate according to each following angle; and performing sealing and cutting length compensation according to the length error betweena sealing and cutting point and a color code signal. According to the invention, the starting curve and the stopping curve of the slave shaft are reasonably designed, so that the equipment can be quickly restarted after being shut down, the control period of the equipment is shortened, the data acquisition precision and the sensor detection sensitivity are improved, and the productivity is improved on the premise that the yield is ensured. In addition, the packaging length can be automatically compensated on line, shutdown and manual intervention are not needed, and the operability and efficiency of the equipment are improved.
Description
technical field [0001] The invention relates to the field of packaging equipment, in particular to a control method and system for a straw packaging machine, and a computer-readable storage medium. Background technique [0002] Straw packaging machine is a kind of equipment that automatically packs drinking straws into bags. The whole machine is composed of transmission system, film automatic tension unwinding device, pipe filling device, automatic sealing and cutting device, finished product conveying device, etc., bag forming, filling, packaging Finished at once. Among them, the speed and precision of automatic sealing and cutting directly affect the efficiency and yield of packaging. [0003] At present, the control of the straw packaging machine is mainly completed by the programmable logic controller (PLC) with the function of flying shear or wheel cutting. The PLC with the function of wheel cutting is used as the main control. The PLC with this function is expensive ...
