Bottle inspection and elimination device and working method thereof

Abstract

The invention relates to a bottle inspection and elimination device which can rapidly and stably eliminate unqualified bottles and does not influence the passing of qualified bottles. The bottle inspection and elimination device comprises a plurality of elimination fingers which are sequentially and adjacently arrayed along the conveying direction of bottles from short to long, wherein when bottles are detected to have no cover, have inclined covers or have no aluminum film, the plurality of elimination fingers are forwards turned to be in the horizontal state from the vertical state in sequence and then are reset; the longest elimination finger is used for conveying the bottles into an entrance of a rotary table type recycling mechanism so as to stably and rapidly eliminate the unqualified bottles and prevent the bottles from falling down; meanwhile, the subsequent passing of qualified bottles is not influenced.

Description

technical field [0001] The invention relates to a bottle inspection and rejecting device and a working method thereof, which are used for rejecting unqualified bottles on a bottling production line. Background technique [0002] In the existing bottling production line, each manufacturer has equipment to detect the quality of the empty bottle or the capping of the finished product after filling, which is used to detect whether the bottle has a cap, whether the cap is tilted, whether there is an aluminum film on the bottle mouth, etc. When unqualified bottles are detected, the bottles are removed by rejecting equipment. The removal task on the existing production line mainly uses the cylinder to push a hitting block, and when the bottle body to be removed reaches the removal position, the bottle is hit to other channels. The impact of this method is relatively large, which will cause the normal bottle to fall; on the other hand, the hit part must be the center of gravity of ...

AI Technical Summary

Problems solved by technology

The impact of this method is relatively large, which will cause the normal bottle to fall; on the other hand, the hit part must be the center of gravity of the bottle, otherwise the bottle will appear unpredictable motion state after being hit, causing other bottles to fall, so The position adjustment requirements of the hitting device are very high

Therefore it is necessary to use a device to solve the above problems, such as the Chinese Patent Publication No. CN 102500560A, a multi-stage rejecting device is used to remove unqualified bottles from the conveying line, but the rejecting fingers are located on the conveying line In general, the height of the finger relative to the conveying line remains unchanged. When the height of the bottle on the production line changes greatly, the height of the rejecting finger needs to be adjusted manually, which has poor adaptability. When used in a bottle production line of various sizes, its production efficiency is low. Low
