Stacking and collecting mechanism, stacking and collecting method and quality testing machine for small-size prints

Abstract

The invention discloses a stacking and collecting mechanism, a stacking and collecting method and a quality testing machine for small-size prints. The stacking and collecting mechanism comprises two main wallboards. The two main wallboards are partially provided with clapping devices. A stacking output device is arranged under the clapping device. The clapping device comprises a supporting beam mounted between the two main wallboards. One end of the supporting beam is connected with a cam mechanism. A pair of lateral pushing boards is mounted on the supporting beam, and is used for pushing two lateral sides of prints. A rear pushing board is arranged between two lateral pushing boards, is connected with the supporting beam through a supporting rod and a slope driving mechanism, and is used for hooking-in and clapping the upper surface of the prints. The stacking output device comprises a lifting platform which is driven to move up and down by a lifting motor through a lifting conveying mechanism. The stacking and collecting method and the quality testing machine for small-size prints are realized based on the stacking and collecting mechanism. Automatic stacking and collecting of the small-size prints are realized at a high speed in high efficiency with low vibration and noise.

Description

technical field [0001] The invention relates to a small-sheet printed matter stacking and collecting mechanism, a stacking and collecting method based on the small-sheet printed matter stacking and collecting mechanism, and a small-sheet printed matter inspection machine, belonging to the field of printed matter detection and stacking. Background technique [0002] Currently, if figure 1 As shown, the existing small-sheet printed product inspection machine includes a surface quality inspection mechanism 10, a waste discharge mechanism 30, a paper delivery mechanism 40, and a stacking collection mechanism 50 arranged in sequence. A primary deflection correction mechanism 20 may also be provided. Such as figure 1 , the surface quality detection mechanism 10 comprises a suction conveying device 11, a suction device 12 installed below the conveyor belt of the suction conveying device 11, and a detection device 13 installed above the suction conveying device 11, the surface qua...

AI Technical Summary

Problems solved by technology

[0003] Although the existing small-sheet printed matter inspection machine can realize the purpose of stacking and collecting the printed matter after the surface quality inspection, there are still the following defects: First, the clapping device 51 in the stacking and collecting mechanism 50 is powered by a cylinder. Therefore, the noise during operation is very large, and the vibration of the cylinder of the pneumatic component is relatively large, which can easily cause resonance of other mechanisms, which can easily affect the detection results and cause false detection; second, the stack output device 52 only adopts double slide rail structure, there is a hidden danger of structural instability
