Embodiment Construction

[0033] Next, an embodiment (first embodiment) of an overlap detection device according to the present invention will be described with reference to the drawings.

[0034] FIG. 1 shows a printing machine 1 provided with an overlap detection device 2 in this embodiment. The printing machine 1 includes: a printing unit 3 and a conveying unit 4 , the printing unit 3 is used for printing; the conveying unit 4 is used for conveying individual sheets to the printing unit 3 one by one. The conveying part 4 includes: a paper feeding board 5, which is used to place the single sheets of paper P successively sent out by the lifting platform not shown in the figure, and conveys them to the downstream side; The front ends of the sheets of paper P are connected, and the position of the sheet P is adjusted; the swing claw 8 is used to clamp the front end of the adjusted sheet P, and move the sheet P toward the printing section 3. The paper feed roller 7 feeds paper.

Abstract

An overlap detection apparatus mounted to a printing press includes a sheet detection sensor for detecting whether a portion of the sheets passing a given position is a non-overlapping portion or an overlapping portion; a signal output section for outputting an overlapping signal on the basis of the detected results of the sheet detection sensor, in which the overlapping signal takes a first form for the overlapping portion and takes a second form for the non-overlapping portion; and a determination section for determining that the sheets of paper are being correctly conveyed while each being displaced by a given amount from an upstream sheet of paper in the conveying direction and overlapping the same when a portion of the overlapping signal taking the first form is equal to a given reference portion, and determines that the sheets of paper are not being correctly conveyed when the portion of the overlapping signal taking the first form is not equal to the given reference portion.

Description

technical field [0001] The present invention relates to an overlap detection device and an overlap detection method capable of detecting whether a conveyed single sheet is one. Background technique [0002] Currently, it is known that it is installed in a conveying section for continuously conveying the sheets in a state where the sheets on the upstream side of the conveying direction are shifted by a predetermined amount in the conveying direction, and for printing and feeding them one by one by the conveying section. The overlapping detection device in the printing machine of the sheet-fed printing part includes: a sheet-fed detection sensor, a signal output part, and a judging part, wherein the sheet-fed detection sensor is used to detect that the conveyed sheet passes through the specified Whether the position is 1 sheet; the signal output unit is used to output the first state (for example: H state) when the single sheets are overlapped, and the second state ( For exam...
