Packaged food packaging inspection method and matched inspection equipment

Abstract

The invention relates to the technical field of packaging and inspection, in particular to a packaged food packaging inspection method and matched inspection equipment. The method comprises the steps that after the food packaging process is completed, packaged food is fed to a first-stage conveying production line; packaging boxes on the first-stage conveying production line are weighed through an electronic scale; whether the packaging boxes weighed by the electronic scale are qualified or not is judged; after the packaging boxes are weighed by the electronic scale to be qualified, the packaging boxes continue to enter a second-stage conveying production line, and transfer conveying is completed; otherwise, the packaging boxes enter a reinspection conveying production line; the packaging boxes entering the reinspection conveying production line are reinspected through manual disassembly inspection and are reloaded with food meeting requirements, and packaging is performed to form secondary qualified packaging boxes; and the packaging boxes obtained after transfer conveying are delivered out of a warehouse and loaded onto a truck. According to the inspection method, whether the current packaging boxes meet requirements or not is judged by performing electronic weighing and comparing the electronic weighing result with a preset standard weight value, the operation is easier and faster, the inspection method can be applied to various kinds of food, and the defect of X-ray irradiation is avoided.

Description

technical field [0001] The invention relates to the technical field of packaging and inspection, in particular to a packaged food packaging inspection method and matching inspection equipment. Background technique [0002] Packaging foods usually need to be packaged in outer packaging before production. There are various packaging forms and materials, mainly including carton packaging and plastic box packaging. Empty packaging often occurs on the packaging production line. The empty packaging phenomenon is mainly It refers to the phenomenon that the food to be packaged is missing in the packaging box during the food packaging process, thus making the packaging box hollow. [0003] Since the overall number of packaging boxes on the production line is relatively large and the appearance of the same batch of packaging boxes is basically the same, it is impossible for inspectors to accurately select empty unqualified packaged food from a large number of packaging boxes.

Problems solved by technology

[0003] Since the overall number of packaging boxes on the production line is relatively large and the appearance of the same batch of packaging boxes is basically the same, it is impossible for inspectors to accurately select empty unqualified packaged food from a large number of packaging boxes. Many units use X-ray irradiation to irradiate the inside of opaque packaging boxes to achieve the purpose of identifying empty packaging boxes, but this identification method also has two disadvantages: one is that the existing methods only Can carry out simple identification of whether the interior is empty or not. After the identification, it is still necessary to manually pick out the empty packaging boxes. It still requires operators to spend a lot of labor to complete the selection work. The entire screening system is not perfect, and there is no follow-up improvement. The second is that for some more important and directly practical infant foods, exposure to X-rays will produce certain unhealthy factors.
