Embodiment 1

[0077] As shown in FIG. 1 , a printing machine 1 is formed of a feeder 2 , a printing unit 3 located behind it, and a transfer unit 4 located behind the printing unit 3 . The transfer unit 4 is equipped with a picking device 5 which implements a picking method according to one embodiment of the invention and which itself also corresponds to an embodiment of the invention.

[0078] The feeder 2 is equipped with a paper feeding device 6 for feeding paper sheets 100, which are sheets stacked on each other, one by one. Each sheet of paper 100 fed by the paper feeding device 6 is conveyed to the conveying rollers 8 and 9 via the feeder plate 7 and a swing arm pivot pre-gripper not shown. Then, each sheet 100 is conveyed from the conveying roller 9 to the platen roller 10 .

[0079] In the printing unit 3 , an intaglio roll 11 adjoins an embossing roll 10 . Three Chablon rollers 12 adjoin the intaglio roller 11 . The Chablon roller 12 has an inking unit 13 attached thereto. Thus...

Embodiment 2

[0233] FIG. 21 shows an outline of a sorting device according to Embodiment 2. This picking device is also integrated into the unloading unit of the printing press.

[0234] The structure of the feeder and the printing unit in the printing machine is the same as that of the conveying unit and the printing unit shown in FIGS. 1 and 2 . In their transfer units, seven stacked plates 61a, 61b, 61c, 61d, 61e, 61f, 61g and 61h are provided. In the portion on each of the stack plates 61a to 61g, the same delivery cam device as shown in FIG. 3 is provided. In a portion above the stack plate 61h, a fixed delivery cam is provided.

[0235] The first two stacking boards 61a and 61b are stacking boards on which good-quality sheets are unloaded. That is, the first two stacking plates 61a and 61b are positions for unloading good products, respectively, and the conveying cams located above the respective plates are good product paper unloading means.

[0236] The stacking boards 61c to 61g...

Embodiment 3

[0241] 22 and 23 show examples of grouping different from the above-mentioned embodiment.

[0242] The case of printing patterns of 5 columns and 8 rows on each sheet 100 is the same as in the previous embodiment. This grouping is done by dividing the patterns into groups, each group comprising 10 small cut paper sheet printed products 101 . Groups a, b, c, d and e are formed such that each group extends into two adjacent columns (the boundaries between groups are indicated by the thick black lines in Figures 22 and 23).

[0243] In addition, in the case of grouping the patterns in this way, each sheet of which all the patterns have no defects is sorted out as a good product sheet, and each sheet of paper having a defective pattern in only one of the groups a to d is sorted out. Picked as a single set of defective sheets, sheets each having a defective pattern in a plurality of sets a to d are picked as multiple sets of defective sheets.

[0244] Even if there is a defective...

Abstract

Disclosed is a sheet sorting method in which, on paper sheets (100) each with a plurality of identical patterns (101) printed thereon side by side in a longitudinal direction and in a lateral direction, a quality of the patterns thereof is inspected; in a case where the quality of the patterns on the sheets in all of groups into which the plurality of patterns are grouped is determined to be non-defective, these paper sheets are discharged to non-defective sheet discharge locations; in a case where a defect is determined to exist among the patterns in only one of the groups on each of the sheets, these paper sheets are discharged to single-column defective discharge locations (single-group defective sheet discharge locations); and in a case where defects are determined to exist among the patterns in a plurality of groups on each of the sheets, these paper sheets are discharged to plural-group defective discharge locations.

Description

technical field [0001] The invention relates to a method and equipment for sorting printed paper according to printing conditions. Background technique [0002] As a printing machine for printing banknotes and security documents, there is a printing machine equipped with a quality inspection device between a printing unit and a conveying unit. In such printing presses, a large number of patterns, each corresponding eg to a banknote or a security document, are printed in a matrix on each sheet in a printing unit. Then, good and bad products of the paper printed in this way are identified by the quality inspection device. Thereby, the good products are transferred to the transfer table for the good products in the transfer unit, and the defective products are transferred to the transfer table for the defective products. Even one defect in any one of the multitude of printed patterns in the matrix causes the sheet to be identified as defective. [0003] The applicant of the ...
