A logistics path planning and control method for a cold-rolled pallet transportation line

Abstract

The invention relates to a logistics path planning and controlling method for a cold rolled tray transport line. The method comprises the following steps: S1, dividing working paths; S2, presetting the working paths for trays, and dividing a plurality of target positions in the working paths successively along the moving directions of targets; and S3, receiving limiting signals at the target positions on the preset working paths in real time, judging whether the trays are stopped precisely and whether the target positions are empty or not according to the limiting signals, wherein if the trayis stopped precisely in the current target position, the next target position in the target moving direction is empty, and controlling the tray to move toward the next target position sequentially according to the preset working path and otherwise, waiting in the current target position. Compared with the prior art, the actual logistics path in the field is optimized, and path planning and automatic control are put forward, so that the carrying trays move to the target positions automatically without human interference, and therefore, various manual errors are reduced and operation is stable and reliable.

Description

technical field [0001] The invention relates to the technical field of cold rolling equipment, in particular to a logistics path planning and control method for a cold rolling pallet transportation line. Background technique [0002] As an important auxiliary equipment, the pallet transportation system used on the cold rolling mill undertakes the logistics transportation on the production line, which is a key factor affecting the production efficiency of the whole line. At present, combined with the on-site working conditions, the pallet transportation system can only adopt the button-type manual operation mode: first, the operator selects the transportation roller table to be operated on the touch screen operated by the transportation system; then, the operator presses the corresponding roller table The button in the action direction controls the motor of the roller table to realize the movement of the loading tray on the roller table in the specified direction, and it can ...

AI Technical Summary

Problems solved by technology

[0004] 1. The entire line of the pallet system is long, there are multiple operating stations and manual operations are required in sections, which reduces efficiency and increases labor costs;

[0005] 2. In the process of logistics operation, there are movements such as pallet turning and turning around. The functional design that only allows two positions on the line at a time makes the aforementioned operations very complicated and time-consuming;

[0006] 3. There is a large uncertainty in human operation, which leads to errors in material transportation;

[0007] 4. The operating habits of different personnel increase the risk of equipment failure;

[0008] 5. The positioning device used by the transportation line equipment is an electromagnetic induction limit switch. The sensing distance of this type of limit switch is quite limited, and there are often situations where the target position is not accurately positioned.

[0009] Due to the above problems, the logistics operation of the entire cold rolling mill production site is chaotic and inefficient, and a large amount of auxiliary time is consumed in logistics operation, which seriously restricts the overall operating rate of production equipment and increases production costs.
