Embodiment Construction

[0034] The present invention is a RMB double-sided offset printing on-line detection good second printed product automatic separation and delivery device, as shown in Figure 4 the improved online detection schematic diagram of the banknote printing offset printing machine of the present invention, a small machine side 01 is installed in the original paper delivery machine side 03 And the detection rollers 09, 10, delivery roller 07 and delivery sprockets 05, 06, 12 on the small machine side 01, etc., complete the installation of the online detection system, and set the blowing pressure paper on the surface of the detection roller close to the detection point device to ensure that the printed matter is close to the surface of the cylinder and improve the accuracy of detection.

[0035] On the premise of keeping the total length of the banknote printing offset printing machine unchanged, an online detection roller and a second delivery bin are added to the original banknote print...

Abstract

The present invention relates to improvement of Reminbi double-side offset printer, and is especially the on-line detection method of Reminbi double-side offset printing quality and automatic separation method of qualified product and inferior. The Reminbi double-side offset printer with functions of separating qualified product and inferior and collecting paper has one increased on-line detection roller, one increased second paper collecting bin and one increased paper collecting chain wheel. By means of the connected chain wheels, detection roller and paper handing roller, the Reminbi double-side offset printer realizes the separation of qualified product and inferior and the separate collection of qualified product and inferior.

Description

Technical field [0001] The present invention relates to the method for automatic separation and delivery of paper for double-sided offset printing of RMB on-line detection of good and bad printing products, which relates to the improvement of double-sided offset printing printing machinery of RMB and the automatic separation and delivery of good and bad products by using the improved device, and particularly relates to the online detection of printing quality of offset printing machines And a paper delivery method with automatic separation of good and bad products. Background technique [0002] Offset printing is the first process in RMB printing. It will produce many defects during the printing process, such as lack of printing, ink dots, cross-color, rubbing, and inconsistent ink color. If these defects cannot be effectively controlled and eliminated in a timely manner, it will directly affect the quality of the product and endanger the reputation of the RMB. Therefore, du...
