Box-manufacturing device

Abstract

The invention provides a box-manufacturing device 1 for blank detection in box manufacture process. The box-manufacturing device 1 is provided with a paper supply part 13 and a conveyor part 2 which conveys a blank 4 supplied by the paper supply part 13 to a box-manufacturing part 3; the box-manufacturing device 1 is provided with a blank detection part which comprises a shooting unit 5, a comparison unit 15 and a flaw detection unit, wherein the shooting unit 5 shots the single side or both sides of the blank 4 supplied by the conveyor part 2; the comparison unit 15 compares detecting images shot by the shooting unit 5 with a main image of the blank 4 as a detection object; and the flaw detection unit uses a part above a preset permitted value as a flaw part for detection when a comparison value obtained by the comparison unit 15 is above the preset permitted value.

Description

technical field [0001] The present invention relates to a box making device for inspecting blanks conveyed to a box making section. Background technique [0002] As an inspection of whether the printed matter to be boxed is acceptable, an inspection device is arranged in the printing machine, and when the printed matter is discharged from the printing machine, the qualified printed matter and the unqualified printed matter are distinguished and discharged. [0003] However, due to the occurrence of flaws, dirt, cutting chips, cutting position deviation, etc. in the process of cutting and scribing the qualified printed matter, the blank after cutting must be inspected. Especially for boxes (boxes) in which foods are to be contained, it is necessary to prevent foreign matter such as cutting chips from being mixed in. In addition, for boxes used for pharmaceuticals, it is strongly required not only to prevent contamination of foreign matter, but also to exclude red printing de...

Problems solved by technology

In addition, when blanks are taken out one by one from the supply unit of the box making apparatus, flaws may also occur on the blanks.

[0008] On the other hand, although it is also possible not to inspect the blank, but only to inspect the state after the box is made, it is not only very difficult to inspect the inner surface side of the box after the box is made, but also when it is near the glued part and When there is red dirt on the folded part, it is more difficult to detect and find the red dirt, and there is also an inspection that can only be detected in the blank state, and it is unrealistic to omit the inspection in the blank state
