Dynamic weighing detection device with self-learning function

Abstract

The invention discloses a dynamic weighing detection device with a self-learning function and in particular relates to the field of product package production. The device comprises a dynamic check weigher, an industrial control computer, a programmable logic controller and a plurality barcode scanners, wherein the dynamic check weigher, the industrial control computer, the programmable logic controller and the barcode scanners are mutually connected and communicate with each other by virtue of an Ethernet gateway, a digital quantity input port of the programmable logic controller is connectedwith an entrance photoelectric switch signal, a digital output port of the programmable logic controller is connected with a rejection cylinder. The device is mounted on a product conveyor line, whena product on the product conveyor line passes the device, two barcode scanners scan a project code and a case code at the same time, when both of the two barcodes can be scanned, a working mode is setto be consistency comparison, if consistency is achieved, whether weight is in a normal range is judged, if the weight is in the normal range, the product is released, and if the weight is not in thenormal range, the product is rejected; and if the consistency is not achieved, the product is rejected as a product with abnormal barcodes no matter whether the weight is qualified or unqualified.

Description

technical field [0001] The invention relates to the field of product packaging production, in particular to a dynamic weighing detection device with an automatic learning function. Background technique [0002] Weight is a basic quality index of a product, which is directly affected by factors such as production technology, raw and auxiliary materials, and performance of product processing and packaging machinery. As the last inspection procedure before products are put into storage, dynamic weighing inspection plays a key role in preventing defective products from entering the market. [0003] In the product production line, it is usually necessary to weigh and inspect the packaged products to detect whether there are missing parts or insufficient weight of the products, and reject unqualified products. In order to save costs, the factory merges multiple product packaging lines and transports them to the finished product warehouse, so that there are many kinds of products ...

AI Technical Summary

Problems solved by technology

[0004] To sum up, the traditional product dynamic weighing detection device requires the user to set the working mode and set parameters, but in the actual use process, the product dynamic weighing detection device usually faces complex working conditions and unattended situations. If the parameters cannot be updated in time, it will cause a large number of false rejects and even stop the entire production line
