Bar code printing quality rating and classified delivery device for printed matter quality inspection

Abstract

The invention relates to a bar code printing quality grading and classified delivery device for printed matter quality inspection. The bar code printing quality grading and classified delivery device comprises a rack, a printed matter bar code quality grading mechanism, a printed matter conveying mechanism, a speed reduction transferring device, a printed matter bar code spectrum obtaining mechanism, a printed matter classified delivery recycling mechanism and a control device. The printed matter conveying mechanism comprises a conveying disc, a disc driving device and a plurality of material receiving and adsorbing assemblies, and all the material receiving and adsorbing assemblies are arranged on the peripheral surface of the conveying disc; the speed reduction transfer device, the printed matter bar code spectrum obtaining mechanism and the printed matter classified delivery and recovery mechanism are sequentially arranged from front to back in the rotating direction of the conveying disc. According to the invention, presswork conveyed by a current domestic printing quality inspection machine can be transferred, accurate speed reduction can be realized, the working efficiency can be improved, and the barcode printing quality of the presswork can be automatically subjected to acceptance inspection, rating and classified delivery and recovery; and the detection consistency with that of a bar code detector for checking and accepting a printed matter receiver is kept.

Description

technical field [0001] The invention relates to the technical field of printing quality detection, in particular to a barcode printing quality rating and classification delivery device for printing product inspection. Background technique [0002] Cigarette label printing is a large-scale and high-precision printing operation in the printing business. It has many processes and needs to be inspected at the same time. The quality inspection of traditional cigarette label printed matter is to use experienced quality inspectors to conduct human eye sampling inspection, which is not only inefficient, but also cannot be fully inspected in a short period of time. [0003] At present, with the increasing recognition accuracy and efficiency of printing quality inspection machines, domestic cigarette label inspection machines of various structures have gradually appeared in the market. The barcodes on the finished products cannot all pass the barcode detector of the tobacco company. ...

Problems solved by technology

The quality inspection of traditional cigarette label printing is to use experienced quality inspectors to conduct random inspections with human eyes, which is not only inefficient but also unable to complete inspections in a short period of time

[0003] At present, as the recognition accuracy and efficiency of printing quality inspection machines are getting higher and higher, domestic cigarette label inspection machines with various structures have gradually appeared on the market. However, the cigarette labels that have passed the current domestic cigarette label inspection machines The barcodes on the finished product cannot all pass the barcode detector of the tobacco company. The main reason is that the shooting detection device provided by the current domestic cigarette label inspection machine is based on image processing and pixel comparison. As a result, the current domestic cigarette label inspection Due to multi-scale threshold judgment conflicts, it is difficult to directly develop the barcode recognition function; while the barcode detector used by the tobacco company for acceptance is imported and uses spectral parameters for characterization and comparison. Inconsistencies in principle and accuracy may easily lead to disputes over the quality acceptance of cigarette label barcode printing and unnecessary printing waste, and the barcode detector used by tobacco companies for acceptance inspection will slow down the recognition rate of cigarette label barcodes due to manual sampling and detection recovery methods, which is different from the current The speed of the cigarette label inspection machine is nearly an order of magnitude worse, and cannot match the speed of the current domestic cigarette label inspection machine
