Online detection system for adhesion of straws to packing boxes

Abstract

The invention relates to an online detection system for adhesion of straws to packing boxes, which is disposed on a milk packaging line comprising a transmission chain. The detection system comprises guide rails arranged on two sides of the chain, an electric eye and a proximity switch are arranged on two opposite sides of the guide rails, the proximity switch is connected with a detection plate, an electromagnetic valve, an air pipe and an electric bag blowing nozzle are arranged on the same side of the proximity switch, the air pipe and the electric bag blowing nozzle are connected with the electromagnetic valve, and the electric eye, the proximity switch and the electromagnetic valve are controlled by the control unit. The electric eye is used for detecting milk bags, and when a straw on the packaging box is abnormal, the lower end of the straw cannot contact with the detection plate to lead the detection plate to deflect, the proximity switch connected with the detection plate is normally opened, the control unit controls the electromagnetic valve to get powder for starting pneumatic equipment, and the electric bag blowing nozzle blows down the milk bag. By means of the online detection system, the problem that manual detection and unqualified product selection are low in efficiency is solved, and production normality is guaranteed.

Description

technical field [0001] The invention relates to the field of milk packaging detection, in particular, the invention relates to an online detection system for pasting straw packaging boxes. Background technique [0002] In the production process of milk aseptic packaging boxes, there is a process of pasting straws. In this process, there are strict regulations on the position and pulling force of straws. inevitable. In order to reduce the product packaging problems caused by the above situations, currently only defective products can be manually screened out. Due to the large output, it takes a lot of manpower to do so, and the labor intensity of the workers is relatively high, and they are prone to visual fatigue during the work process. [0003] The currently used straw machine does not have an automatic product packaging inspection system, which cannot meet the needs of an advanced production line with a high degree of automation and a small number of staff.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problems that the existing straw machines cannot distinguish whether there are straws or whether there are straws and sticking tubes on the upside down. The present invention provides an online detection system for sticking straw packaging boxes, which can identify There is an automatic detection device for whether there is a straw on the package and the position of the straw. This detection device can not only detect whether there is a straw on the package, but also distinguish the sticking position of the straw on the package, and separate unqualified products
