Problems solved by technology
This method is simple to control, and its disadvantage is that frequent speed adjustment is required, and multi-lines cannot quickly reach a stable state of synchronization. In addition, during the production process, due to different load conditions of multiple lines, the encoder pulse counts may be the same. However, the actual position of the conveyor line is different, and there is a cumulative error. After a long time, the position can no longer be synchronized, and manual calibration is required.

Embodiment Construction
[0028] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0029] Take the hanging conveyor line of a sheep slaughtering production line as an example, including the horizontal pre-stripping conveyor line L1 for the front legs, the L2 blood-killing conveyor line, the L3 horizontal pre-peeling conveyor line for the hind legs, the quarantine conveyor line L4 for the head and hoof, and the visceral carcass conveyor line L5, red and white visceral health inspection conveyor line L6, each conveyor line is driven by a chain, and a hook is hung every 1m. In the process...

The invention provides a multi-line automatic synchronous control method for a suspended conveying line. By converting the multi-line synchronous control problem into a plurality of double-line synchronous control problems, the main process of the double-line synchronous control and the cumulative position error correction process are adopted to realize multi-transportation. The position and speed between the lines are synchronized. Compared with the existing technology, it has the advantages of fast and stable synchronous control, less overshoot, and can eliminate accumulated errors. It improves the automation level, production efficiency and operation quality of the slaughtering production line.
Description
technical field [0001] The invention relates to the field of slaughter production automation, in particular to a multi-line automatic synchronous control method for a suspension conveying line. Background technique [0002] With the high level of economy and the advancement of science and technology, the scale of slaughter continues to expand, and its production process has experienced the development from manual slaughter to automated slaughter. In the field of slaughter production automation, it usually includes multiple hanging conveyor lines, through which materials are transferred between different processing techniques. These conveyor lines generally require synchronous control of speed and position to avoid frequent movement of staff, reduce labor intensity, and improve work efficiency and processing quality. [0003] Chinese Utility Model, Patent No. 20142000192.4 discloses a multi-line synchronous control system for slaughtering and hanging automatic conveyor lines...
