Example Embodiment

[0022] Example one

[0023] figure 1 A structural diagram of a defect detection system of a paper provided by the embodiment of the present invention, the present embodiment can be applied to the oblique detection of paper.

[0024] Such as figure 1 As shown, the defect detection system of one paper provided in the embodiment of the present invention, includes: a first stage detecting device 12 and a secondary detecting device 13 fixed to the transmission 11, and the transmission 11 for transmitting the paper.

[0025] In the present embodiment, the transmission can be means of a transfer function such as a conveyor belt. The transmission transmits the paper transfer sequentially by the first stage detecting device and the secondary detecting apparatus that is fixed to the conveying device, the primary detecting device is a device for detecting a complete overlapping double sheet in the paper tape. The secondary detection device is The device used to detect the flawed paper that ...

Example Embodiment

[0097] Example 2

[0098] image 3 Is a flowchart of a method for detecting defective sheets according to a second embodiment of the present invention is applicable to the case of detecting flaws in the sheet of the present embodiment, the method may flaw detection system provided by the above-described embodiments the sheet is performed.

[0099] Such as image 3 , The method includes the following steps:

[0100] S101, complete overlap of the double sheet detection on the sheet to be measured by a transmission detecting means.

[0101]It should be noted that the transmission is a device that transmits the paper detection of the paper to be tested, and the primary detecting device is fixed to the transmission to perform a complete overlapping double detection of the paper tape. The ultrasonic sensor and the first control module are mounted in the primary detecting device, and the ultrasonic sensor is connected to the first control module via a single detection signal line and a du...

Abstract

The invention discloses a paper flaw detection system and method. Comprising a first-stage detection device and a second-stage detection device which are fixedly arranged on a transmission device, and the transmission device is used for conveying paper to be detected; the first-stage detection device is used for detecting completely overlapped double pieces of paper to be detected on the transmission device; and the secondary detection device is used for detecting defective paper on the paper to be detected on the transmission device, and the defective paper comprises two pieces of paper which are not completely overlapped. According to the embodiment of the invention, a double-sheet detection function can be realized, so that the problem of defect missing detection caused by double sheets is avoided.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of double-sheet detection, and in particular, to a paper defect detection system and method. Background technique [0002] With the continuous development of printing technology, the printing industry's requirements for the quality of printed products have also been continuously improved, and the quality control has even become so fine that a "defective product" is not allowed to flow into the downstream market, especially the barcode defects or trademarks on the products in circulation. defect etc. Without considering special circumstances, the relatively advanced visual inspection equipment on the market can already meet the demand of not letting go of any defect. [0003] However, there is a special case where defect detection cannot be achieved by visual inspection: double sheets. Once the product to be inspected passes through the visual camera in the form of completely overlappi...
