Paper feed machine for product check machine and paper feed method thereof

Abstract

The invention discloses a paper feed machine for a product check machine and a paper feed method of the paper feed machine. The paper feed machine comprises an uninterruptible paper feed mechanism. An induced draft paper supply mechanism is correspondingly arranged above the upper paper outlet end of the uninterruptible paper feed mechanism. A paper aligning plate is vertically arranged on one side of the uninterruptible paper feed mechanism and corresponding to the output end of the induced draft paper supply mechanism. The output end of the induced draft paper supply mechanism and the input end of a blowing paper distributing mechanism are correspondingly arranged. The paper feed method includes the steps that a main paper feed table and an auxiliary paper feed table alternatively support and lift a printed matter stack with printing surfaces placed upwards; printed matter is uninterruptedly supplied to the induced draft paper supply mechanism; the induced draft paper supply mechanism continuously adsorbs a single sheet of printed matter from the position above the printed matter stack and transfers the single sheet of printed matter to the blowing paper distributing mechanism, and then the blowing paper distributing mechanism sends out the single sheet of printed matter after separating the single sheet of printed matter from the induced draft paper supply mechanism. By the adoption of the mode of adsorbing paper feed with the printing surfaces placed upwards, the single sheet of printed matter is uninterruptedly conveyed to a surface quality detector for surface quality detection, and therefore scratches of the printing surfaces of the printed matter are reduced or eliminated.

Description

technical field [0001] The invention relates to a paper feeder for a product inspection machine and a paper feeding method based on the paper feeder, belonging to the field of product inspection machines. Background technique [0002] Currently, if figure 1 As shown, the existing inspection machine (also known as the inspection machine for small-sheet printed matter) generally includes a paper feeder 10, a deviation correcting machine 20, and a surface quality inspection machine 30, wherein: the paper feeder 10 includes a paper feeding transmission mechanism 11 and its upper Correspondingly arranged paper feeding knife 13 and paper supporting board 12, the paper output end of paper feeding knife 13 and the upper plane of the conveyor belt of paper feeding transmission mechanism 11 are separated by a gap, the gap is the paper outlet, and the size of the paper outlet is one The thickness of a printed matter 40; the deviation correction machine 20 includes a pair of deviation ...

AI Technical Summary

Problems solved by technology

[0003] As can be seen from the above description, although the existing paper feeder 10 can achieve the purpose of continuous output of printed matter 40 one by one, it still has the following defects: first, the existing paper feeder 10 is printed by printed matter 40 Face-up paper feeding method, this paper feeding method is easy to cause a large number of printed products 40 stacked on the top to scratch the printed surface of the lowermost printed product 40, and when output from the paper outlet of the paper feeding knife 13, The paper feed knife 13 is easy to scratch the printing surface of the printed matter, which can easily lead to the scrapping of qualified printed matter and false detection, especially the printed matter with poor surface wear resistance
