Piled plate lifting baffle protection device and control method thereof

Abstract

The invention discloses a piled plate lifting baffle protection device and a control method thereof. The piled plate lifting baffle protection device comprises a piled plate lifting baffle and a piled plate roller way, the piled plate lifting baffle is located at the tail end of the piled plate roller way, the piled plate roller way is further provided with a roller way cover plate, the roller way cover plate is provided with a rectangular opening, and the rectangular opening is located at the position 3 m away from the piled plate lifting baffle. A photoelectric switch installed on a photoelectric switch bracket is arranged above the rectangular opening. According to the control method of the piled plate lifting baffle protection device, a detection signal of the photoelectric switch serves as a speed decrease signal of a PLC control system; when the speed decrease signal is triggered, the linear speed of the piled plate roller way is decreased to 30% of the original speed, and v is equal to 0.6 m/s; and 2.8 s after the speed decrease signal is triggered, the linear speed of the piled plate roller way is decreased to zero, the roller way stops rotating, and v is equal to 0 m/s. By means of the piled plate lifting baffle protection device and the control method of the piled plate lifting baffle protection device, soft contact between the piled plate lifting baffle and a steel plate is achieved, on one hand, strong impact of the steel plate on the lifting baffle is effectively avoided, and the service life of the piled plate lifting baffle is prolonged; and on the other hand, impact noise is eliminated.

Description

technical field [0001] The invention belongs to the technical field of mechanical maintenance, and in particular relates to a protective device for lifting and lowering baffles of pallets and a control method thereof. Background technique [0002] In order to make the pallets tidy and easy to operate, more and more plate collection areas are equipped with mechanical pallet lifting baffles. [0003] In the patent CN 201801204 U, a lifting baffle used for a stacker between steel plate collection platforms discloses a lifting baffle with a simple structure, easy lifting, and a buffer function. The advantages of its technical solution: the impacted rotating baffle It is not easily deformed; the driving cylinder installed at the rear has a buffering effect and is also convenient for hoisting and maintenance; the driving cylinder has low requirements on the working environment and the service life of the cylinder is extended. [0004] In the patent CN2273229Y, a baffle mechanism ...

AI Technical Summary

Problems solved by technology

[0005] The published patent is to optimize the mechanical mechanism of the pallet baffle, which has the function of buffering the impact of the lifting baffle, but does not avoid the strong impact that occurs when the baffle is in contact with the steel plate
