Printed-product detector with printed product in-stack collecting counting device, and operating method thereof

Abstract

The invention relates to a printed-product detector with a printed product in-stack collecting counting device. The printed-product detector comprises a paper feeding part, a detecting part, an in-stack collecting counting part and a waste collecting part, wherein the output end of the paper feeding part is connected with the input end of the detecting part; the output end of the detecting member is connected with the input end of the in-stack collecting counting part; and the in-stack collecting counting part comprises a rejecting cutter, an air blowing device, a layered collection part, a staking part, a stack conveying part and a waste collecting part. An operating method of the printed-product detector comprises the following steps of: conveying printed products to the detecting part for imaging comparison through the paper feeding part pieces by pieces; conveying the printed products to the in-stack collecting counting part for rejecting unqualified printed products and conveying the qualified printed products; conveying the qualified printed products to a first-layer collection part in a parallel manner; lifting the stacking part to a second-layer collecting part after the collection number of the stacking part is up to a preset value; and sequentially carrying out the next-layer stacking operation. The operating method of the printed-product detector, disclosed by the invention, has the advantages of capability of suitably detecting printed-product detectors with high speed, accuracy on counting, direct stacking collection without manual arrangement, and reduced labor number and cost; and in addition, the printed-product detector with the printed product in-stack collecting counting device, disclosed by the invention, has the advantage of simple and convenient combination due to a modular combination.

Description

(1) Technical field: [0001] The invention is suitable for printing machinery, especially for equipment with quality detection function in the printing machinery, that is, a quality inspection machine with a printing product collection and counting device and its working method. (two) background technology: [0002] The market demand for inspection machines is increasing, and it is becoming more and more important to improve the performance of inspection machines. Under the same quality conditions, increasing speed means improving efficiency. [0003] In the prior art, there are two ways of collection of single-sheet printed matter inspection machines: fish scales and stacking methods. Fish scales are collected through the marks of printed matter counting. Although it can be adapted to high-speed detection, it needs to manually collect finished products and arrange them into stacks; stacking The collection can be collected directly into stacks, but the speed of equipment adap...

Problems solved by technology

[0003] In the prior art, there are two ways of collection of single-sheet printed matter inspection machines: fish scales and stacking methods. Fish scales are collected through the marks of printed matter counting. Although it can be adapted to high-speed detection, it needs to manually collect finished products and arrange them into stacks; stacking The collection can be collected directly into stacks, but the speed of equipment adaptation is relatively low. If the speed is too fast, it will cause inaccurate counting of printed products, chaotic paper delivery, paper jams, etc. The bottleneck of this structure is that the auxiliary paper delivery device cannot quickly In order to overcome this defect, the traditional method is to appropriately reduce the speed of the main machine during the handover of the secondary delivery, or directly limit the speed of the main machine to a lower range, so as to realize the separate collection of printed products

In short, the existing technology is troubled by various factors and cannot effectively realize the technology of pile collection at high speed.
