Power and free overhead conveyor synchronous conveying system and synchronous conveying method

Abstract

The invention discloses a power and free overhead conveyor synchronous conveying system, which comprises a conveying chain, a receiving chain, a first frequency converter, a second frequency converter, a programmable logic controller (PLC), and a bearing rail, wherein a handover region of the bearing rail is positioned between a first turning rail region and a second turning rail region, a handover waiting region of the bearing rail is positioned in a second straight rail region, and a handover completion region of the bearing rail is positioned in a third straight rail region; at least two first pushing heads are arranged on the conveying chain; at least two pushing heads are arranged on the receiving chain; at least four fourth sensors are arranged on the chain rail of the conveying chain; at least four fifth sensors are arranged on the chain rail of the receiving chain; both the fourth sensors and the fifth sensors are connected with the PLC; a second sensor is positioned in the handover waiting region of the bearing rail, and a third sensor is positioned in the handover completion region of the bearing rail. The system eliminates the pushing head loss phenomenon radically.

Description

technical field [0001] The invention relates to a synchronous conveying system and a synchronous conveying method of an accumulation type suspension conveyor. Background technique [0002] The product-free suspension conveyor is a kind of transportation equipment suitable for high productivity and flexible production systems. With the wide application of accumulative-free suspension conveyors in modern production workshops, some problems that often occur in the production and operation of this equipment have also been exposed, among which the loss of push heads is one of the most difficult problems to solve and cure among the many vertical problems . [0003] The phenomenon of missing push head refers to the fact that when the accumulation chain is handed over, the trolley is at the position taken away by the push head of the receiving chain, and the trolley is not taken away because the push head of the receiving chain and the lifting claws of the trolley are staggered in ...

AI Technical Summary

Problems solved by technology

[0004] 1) The speed of the receiving chain is fast. When the receiving chain pusher passes the handover position, the conveying chain pusher has not yet reached the handover position, which will inevitably cause the trolley to wait for the next receiving chain pusher at this position

[0005] 2) Reverse deformation of the front shovel of individual trolleys

[0006] 3) The front shovel of the trolley cannot be lowered by its own weight, resulting in the failure of the trolley lifting claw and the chain pusher to engage

Otherwise, due to the inflexible rotation of the lifting claw shaft, the push head of the trolley cannot reach the required height when it goes up and down. , seriously affecting the normal production of the workshop
