Method and device for online detection and rejection of unembossed coins

Abstract

The invention relates to a method and device for online detection and rejection of unembossed coins. The method comprises the steps of: sending coins to a belt conveyor, and spacing out the distances among the coins by utilizing the conveying velocity of the belt conveyor; uniformly spreading the coins in the single-layer state by utilizing a single-layer treatment device; capturing images of thecoins by using a camera or a video camera and transmitting the images to a computer for processing; and figuring out the number and the positions of unembossed coins by a computer, and controlling a rejecting device positioned at the rear end of the belt conveyor to reject the unembossed coins. The device comprises a belt conveyor (5) used for conveying the coins, a feeding mechanism (1) arrangedat an inlet end of the belt conveyor, a single-layer spreading scraper-plate mechanism (2) arranged above the belt conveyor, a visual inspection device (3) arranged above the belt conveyor and positioned at the rear end of the single-layer spreading scraper-plate mechanism (2), a rejecting device (4) arranged at an outlet end of the belt conveyor, and the computer connected with the visual inspection device (3) and the rejecting device (4) in a communication way. According to the method and the device provided by the invention, online detection and rejection of the unembossed coins entrained in embossed coins can be realized.

Description

technical field [0001] The invention belongs to the technical field of coin production quality detection, and in particular relates to a method and device for on-line detection of unprinted white cakes mixed in large-flow flower cakes after printing and removed. Background technique [0002] With the continuous development and progress of new technology and new technology of coin processing, and the in-depth promotion of fine processing in the production process, the processing technology of coins has become more complicated than before, and there are more and more processing procedures, which leads to the control of production quality. The requirements have also increased a lot. [0003] At present, coin processing enterprises generally adopt the method of installing printing testing equipment at the outlet of the printing machine to complete the quality control of the product quality testing, but there is no final testing process for the large-flow discharge link after the...

Problems solved by technology

[0003] At present, coin processing enterprises generally adopt the method of installing printing testing equipment at the outlet of the printing machine to complete the quality control of the product quality testing, but there is no final testing process for the large-flow discharge link after the finished product processing is completed. The probability of production accidents cannot be eliminated, so it is difficult to control the production process with an optimized process flow, so as to achieve the goal of 100% qualified products
