Pallet trolley multi-station conveying system

Abstract

The invention discloses a tray trolley multi-station conveying system. Stations are arranged sequentially on a same system platform according to the assembly process. Tray trolley reciprocating driving mechanisms are independently arranged between previous stations and next stations adjacent to the previous stations, and thus tray trolleys can not only forward go to the next stations from the previous stations in the system conveying direction but also can backward go to the previous stations from the next stations in the reverse system conveying direction to form a trolley reciprocating section. The tray trolleys are used for driving workpieces to go forward or go backward, so that equipment on the same station can be used in different working procedures of the assembly process and are recycled aiming at the different working procedures of the assembly process. The recycle rate of the same equipment among the different stations in an assembly line can be effectively increased, accordingly, the equipment utilization rate is increased, the length of the assembly line is shortened, and the work cycle is improved.

Description

technical field [0001] The invention relates to a pallet trolley multi-station conveying system applied on an assembly line. Background technique [0002] According to the requirements of the assembly process on the production line, it is necessary to use a conveying device to transport workpieces between multiple stations. In the prior art, the transportation between each station is the one-way transmission of the line body tray. Since each station is set on the whole line, and the line body is one-way transmission, when the same equipment needs to be used, only Through the subsequent increase of stations or the use of small ring circular conveying methods. The problem with this method is: because the tray flows in one direction, it can only pass through each station in sequence at one time, and cannot flow in reverse, and each station needs to be equipped with a lifting positioning device, which cannot be used for the same equipment on different stations. Reuse, in the p...

Problems solved by technology

The problem with this method is: because the tray flows in one direction, it can only pass through each station in sequence at one time, and cannot flow in reverse, and each station needs to be equipped with a lifting positioning device, which cannot be used for the same equipment on different stations. Reuse, in the process of the pallet following the movement of the line body, the same equipment needs to be set up repeatedly, which greatly increases the floor area of ​​the assembly line and the configuration cost of the assembly line, and the transmission line between multiple stations is long and inefficient
