Printed matter online detection and waste rejecting device

Abstract

The invention provides a printed matter online detection and waste rejecting device, and mainly relates to the field of printed matter detection equipment. The printed matter online detection and waste rejecting device comprises conveying equipment, detecting and rejecting equipment, a receiving device and a control device, the conveying equipment comprises input conveying equipment, detection conveying equipment, first output conveying equipment and second output conveying equipment, and one end of the input conveying equipment is fixedly connected into the detecting and rejecting equipment; and the detection conveying equipment is fixedly installed in the detecting and rejecting equipment, a guide plate device is rotationally installed on the detecting and rejecting equipment, an image recognition device is arranged in the detecting and rejecting equipment, and the first output conveying equipment and the second output conveying equipment are arranged at the rear side of the detecting and rejecting equipment. The printed matter online detection and waste rejecting device has the beneficial effects that printed matters can be stably conveyed, the detecting and rejecting equipment can rapidly detect the printed matters and control the guide plate device to reject unqualified printed matters, and the product quality of the printed matters is guaranteed.

Description

technical field [0001] The invention mainly relates to the field of printed matter detection equipment, in particular to an online detection and rejection device for printed matter. Background technique [0002] At present, the technology and performance of the printing machine in the domestic printing industry are quite good, but as the service life of the machine increases and the equipment ages year by year, the printing quality of the printed matter will gradually decline. For example, in the printing process, occasionally misregistration or small ink (dirty) spots occur, if the root cause of the problem is not found and found in time, it will seriously affect the product quality and lead to an increase in the scrap rate. [0003] With the continuous improvement of the quality requirements of printed matter, it is necessary to carry out quality inspection on printed matter and recycle printed matter that does not meet the requirements. At present, the commonly used detec...

Problems solved by technology

For example, in the printing process, there are occasional misregistration or small ink (dirty) spots, etc. If the source of the problem is not found and found out in time, it will seriously affect the product quality and lead to an increase in the scrap rate

[0003] With the continuous improvement of the quality requirements of printed matter, it is necessary to carry out quality inspection on printed matter and recycle printed matter that does not meet the requirements. At present, the commonly used detection methods are offline detection or online detection. Offline detection needs to be processed after the printed matter is printed. Detection, due to the long offline detection time, it is easy to cause waste products to be rejected and recycled in time, and the printing speed of modern printing machines is fast, the use of offline detection will cause waste of printing materials and greatly reduce production efficiency; online detection is during the printing process Install a printed matter quality inspection device to detect directly when printed matter is printed, so as to remove waste products in time. Online detection can better and more timely control the quality of the product production process, reduce the waste rate, and thus greatly improve production efficiency. Therefore, online Inspection is currently the most important inspection method for printing machines

[0004] The online detection device collects and compares images of printed matter and judges whether the quality meets the requirements, and then rejects the unqualified printed matter. At present, the existing printed matter detection equipment is less and the general structure is complex and the manufacturing cost is high. Printed matter needs to be conveyed during detection. For transmission, due to the light printing quality, it is easy to break away from the transmission equipment when it is transmitted by conventional transmission equipment
