Problems solved by technology

This method of marking—association or elimination needs to mark the traceability code through frequent operations on the database. When the traceability code is invalid, it needs to release the same group of other marked traceability codes. The judgment of whether the traceability code is valid or not depends on the The status of each traceability code in the database is closely related to the association relationship. The above-mentioned frequent traceability code marks affect the accuracy of the judgment of the validity of the traceability code and production efficiency
[0008] 3. Due to the variety of products, when the packaging ratio, size and production speed change, the acquisition system cannot automatically adapt to the production requirements, and professionals are required to configure and on-site debug the parameters such as scanner switch delay time, focus distance and rejecter action delay time , which consumes a lot of production lead time

Embodiment 1

[0054] Such as figure 1 with figure 2 As shown, this embodiment takes a veterinary drug product with a packaging level of three as an example to illustrate the product two-dimensional code information collection association system and its association method and self-adaptive method. The product two-dimensional code information collection association system, Including the control unit, the conveyor belt and the rack. Since the packaging level of the veterinary drug product is Class III, there are two scanning and labeling mechanisms along the conveying direction of the conveyor belt. Scanning unit, rejecting unit and printing unit, the frame is used to install the various components of the fixed system.

[0055] Such as image 3 , Figure 5 with Figure 7 As shown, the scanning unit includes sensors and scanners arranged along the conveying direction of the conveyor belt; the rejecting unit includes sensors and rejectors arranged along the conveying direction of the convey...

Embodiment 2

[0104] For products with packaging level II, take products with a packaging ratio of 1:4 as an example. The minimum scanned package on the conveyor belt is the minimum label-labeled package (each box), and finally 4 boxes form a box to generate an association relationship. In the case of secondary packaging, the product QR code information collection association system only sets up a scanning and labeling mechanism along the transmission direction of the conveyor belt. The scanning and labeling mechanism includes scanning unit 1, rejecting unit 1, and printing unit 1 for production, and the rest The structure is the same as the first embodiment.

[0105] The working process of the product's two-dimensional code information collection association method is as follows: the system receives the scanned data returned by the scanning unit 1, marks its validity, and stores it in the cache queue. When receiving the trigger signal of the culling unit 1, the system judges the validity ...

Abstract

The invention discloses an acquiring and correlating system for two-dimensional code information of products. The system comprises a control unit, a conveying belt and at least one scanning and labeling mechanism; each scanning and labeling mechanism comprises a scanning unit, a removing unit and a printing unit which are arranged sequentially along the conveying belt; the control unit comprises an industrial personal computer and a control card; the scanning units and the printing units are electrically connected with the industrial personal computer; and the removing units are electrically connected with the control card. Compared with a device adopting multiple logic control units such as a programmable logic controller (PLC) and the like, the system is simpler and more compact in structure, and learning and using costs caused by the connection problems among the different logic units are reduced. The invention provides an acquiring and correlating method for the two-dimensional code information of the products. Database operations are effectively reduced on the premise that accurate correlation and removal of packages are guaranteed, and the accuracy of judgment of validity of traceability codes is improved. The invention further provides a self-adaptation method of the acquiring and correlating system for the two-dimensional code information of the products. Production requirements of the products with different package sizes can be met through just one time of mounting.

Description

technical field [0001] The invention belongs to the technical field of product information traceability, and in particular relates to a product two-dimensional code information collection association system, an association method, and an adaptive method. Background technique [0002] At present, the traceability system of food and medicine has risen to the legal level. Taking drugs as an example, my country launched the drug electronic supervision code system based on one-dimensional barcodes in 2006, and began to implement the traceability code supervision system based on two-dimensional codes in the field of veterinary drugs in 2016. In the veterinary drug traceability code supervision system, the state builds a unified platform, and manufacturers download the traceability code information from the platform, and print or paste it on the product packaging in the form of a QR code. Before the product is out of the warehouse, it is necessary to collect the traceability code ...
