Conveyor chain drop detection device and method

Abstract

The invention discloses a wheel-falling detection device and method for a conveying chain, and relates to the technical field of production line workpiece conveying. The device comprises a control module, an execution module and at least one induction module. The induction module is connected with the control module and used for sending an induction signal to the control module in real time when the conveying chain passes through the induction module. The control module is connected with the induction module and the execution module and sends a command signal to the execution module according to the induction signal sent by the induction module. The execution module is connected with the control module and stops operation of the conveying chain according to the command signal. According to the wheel-falling detection device and method, due to the induction module arranged nearby the conveying chain, the wheel-falling phenomenon can be timely and accurately found, the derailment accident is effectively prevented from happening, and production safety is improved.

Description

technical field [0001] The invention relates to the technical field of workpiece transmission in a production line, in particular to a detection device and method for a dropped wheel of a conveying chain. Background technique [0002] At present, plate conveyor chains are usually used to transfer workpieces on the assembly line of automobile assembly workshops. The structure of the plate conveyor chain is relatively simple, such as figure 1 As shown (the arrow shows the running direction of the conveyor chain): a plurality of long plates 3 are continuously fixed on two parallel chains (not shown), and the workpiece 2 is placed on one or more long plates 3 . like figure 2 As shown, each chain 1 is composed of multiple chain links (shown in the dotted line box in the figure), and each chain link includes two inner chain plates 4 and two outer chain plates 5, the outer chain plate 5 and the inner chain plate 4 The pin shafts 7 are fixed between them, and the part of the pin...

AI Technical Summary

Problems solved by technology

Since the long plate 3 is fixed on the chain 1, the long plate 3 will cover the sprocket 8 below, and the space between the long plate 3 and the sprocket 8 is very small, so maintenance and inspection are very inconvenient

In addition, the phenomenon that the sprocket 8 often occurs is not easy to be found, and the shedding of the sprocket 8 will eventually lead to the derailment of the entire conveyor chain, affecting normal production
