Product information correlation method and device as well as traceability system

Abstract

The invention provides a product information correlation method. The product information correlation method comprises the following steps that a product code of a product on a first station passing through a first preset position is obtained; a packaging code of a packaging body on a second station passing through a second preset position is obtained; the product code and the packaging code are correlated through the station interval number between the first station and the second station. The invention further discloses a product information correlation device and a traceability system comprising the information correlation device at the same time. The product information correlation device comprises a product code module, a packaging code module and a correlation module. The correlationmode of the product information correlation device is accurate and free of errors, the product code and the packaging code can be accurately correlated and matched, the application of electronic devices is reduced, the structure of the correlation device is simplified, operation and maintenance are facilitated, meanwhile, two kinds of practical application scenes where the packaging body is provided with the packaging code and is not provided with the packaging code are considered, moreover, a specific solution is designed, and the application field is effectively expanded.

Description

technical field [0001] The invention relates to the field of product information tracing, in particular to a product information association method, a device for product information association and a traceability system including the product information association device. Background technique [0002] In order to achieve anti-counterfeiting, anti-smuggling, and quality traceability, manufacturers of wine, beverages, medicines, and food products need to associate product codes with packaging codes during the product packaging process. The identification code on the smallest package in direct contact with the product. The packaging code is usually an identification code other than the product code. [0003] For wine products, for example, the wine is usually filled in the bottle, that is, the product code is located on the bottle, and the bottle needs to be packed into a box, that is, the packaging code is located on the first-level, second-level or N-level packaging outside ...

AI Technical Summary

Problems solved by technology

[0003] For wine products, for example, the wine is usually filled in the bottle, that is, the product code is located on the bottle, and the bottle needs to be packed into a box, that is, the packaging code is located on the first-level, second-level or N-level packaging outside the wine bottle. To realize the association between the product code and the packaging code, it is first necessary to obtain the product code and the packaging code. However, due to the internal space structure constraints of each device on the product production line (such as a labeling machine or a wrapping machine), it is impossible to achieve a direct physical association. Take the packing machine as an example, before or before the entrance of the wrapping machine, the packaging code cannot be determined and cannot be associated; after the wrapping machine exits or after the export, the carton has been sealed and the product code cannot be determined and cannot be associated

[0004] In addition, in the prior art, a large number of electronic devices such as sensors and synchronizers are used to achieve logical association. To a certain extent, although the association between product codes and packaging codes can be realized, setting too many electronic devices will not only increase the cost, increase the failure frequency of the device itself, etc., and increase the probability of association errors, such as judging the association relationship through the calculation results of electronic devices (such as synchronizers), a slight calculation error or delay in information collection, or the aging of the equipment itself, combined with the production line. Running at high speed will cause associated errors
