Embodiment Construction

[0069] Hereinafter, the inspection apparatus of the sheet-shaped article of this invention is demonstrated concretely using drawing.

[0070] (Example)

[0071] figure 1 is a side view of an inspection device according to an embodiment of the present invention, figure 2 is the front view of the same inspection device, image 3 is a control block diagram of the same embodiment. also, Figure 4 It is an explanatory drawing of the pattern on the paper. in addition, Figure 5 It is a brief structural diagram of the gravure printing machine, Figure 6 yes Figure 5 Enlarged view of main part.

[0072] like Figure 5 As shown, the gravure printing machine, which is the final printing machine of multiple printing processes for printing not only ordinary patterns but also numbers and stamps, is generally composed of a paper feeding device 10 , a printing device 20 and a paper discharging device 30 .

[0073] A paper feeder 10 on which paper sheets (sheet-shaped pieces) W ar...

Abstract

An inspection apparatus for a sheet includes: white LED illuminators (41a, 41b) which irradiate a sheet of paper (W) with light containing visible light: IR-LED illuminators (43a, 43b) which irradiate the sheet of paper (W) with light containing infrared rays: two visible color cameras (42A, 42B); one IR monochrome camera (44): an IR filter (45) which eliminates the visible light in the light emitted from the white LED illuminators (41a, 41b) and the IR-LED illuminators (43a, 43b) and reflected off the sheet of paper (W), and makes only the infrared rays incident on the IR monochrome camera (44); and a control device (46) which determines appropriateness of a pattern portion (VE) on the sheet of paper (W) on the basis of the visible light made incident on the visible color cameras (42A, 42B), and determines appropriateness of pattern portions (IEa, IEb) on the sheet of paper (W) on the basis of the infrared rays made incident on the IR monochrome camera (44).

Description

technical field [0001] The present invention relates to an inspection device of a sheet-shaped article including a pattern portion printed with ordinary ink and a pattern portion printed with ink containing an infrared component. Background technique [0002] Conventionally, there is a device disclosed in Patent Document 1 as such an inspection device. [0003] The device of the above-mentioned Patent Document 1 includes: a sheet-shaped article holding device, which is provided on the endless conveying member, and holds the end of the sheet-shaped article; The inner side of the loop formed by the above-mentioned moving trajectory is arranged; a plurality of inspection devices are arranged inside the loop of the arc-shaped track; and the guide is arranged outside the loop of the arc-shaped track. The sheet-shaped article traveling along the arc-shaped trajectory portion is inspected by a plurality of inspection devices while being guided by the guide. [0004] And, the abov...
