Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, the banknote paper defect online marking system of the present invention includes a main controller 1, an electrical control component 2, several marking pens 3, a plurality of marking pen driving mechanisms 4 corresponding to several marking pens 3, Frame 5, frame driving mechanism 6 and marking image detection device 7. Several marking pens 3 are arranged on the frame 5, and the frame driving mechanism 6 drives the frame 5 to move. Under the control of the main controller 1 , the electrical control unit 2 controls the marking pen driving mechanism 4 to work, and the marking pen driving mechanism 4 drives the marking pen 5 to move forward or backward to mark on the defective banknote paper 100 . The marked image detection device 7 is used to detect the marked banknote paper image, and transmit the banknote paper image data to the ma...

Abstract

The invention discloses an on-line bank note paper flaw marking system. The system comprises a master controller, an electric control component, a plurality of markers, marker driving mechanisms, a stand, a stand driving mechanism and a marking image detection device, wherein the marker driving mechanisms are in one-to-one correspondence with the plurality of markers; the plurality of markers arearranged on the stand; the stand driving mechanism is used for driving the stand to move; the electric control component controls the marker driving mechanism to work under the control of the master controller; and the marking image detection device is used for detecting a marked bank note paper image and transmitting bank note paper image data to the master controller. By marking the bank note paper with flaws by using the markers, ink pollution can be avoided; and when n markers with different colors are adopted, 2n-1 paper flaws can be marked.

Description

technical field [0001] The invention relates to a banknote paper marking device. Background technique [0002] Paper defect detection is generally aimed at the finished paper before the paper machine is curled. There is no drying device here, and the traditional inkjet method is used for marking. The ink cannot be completely dried within 3 seconds, which will cause the subsequent mechanical mechanism to be polluted by the ink and affect the product quality. If the drying device is added artificially, the product quality will be affected. Use instant dry ink with faster drying speed, the nozzle is easy to clog. [0003] In addition, the existing inkjet marking method has a single color, which can only identify paper defects, but cannot identify the paper defects, which is not convenient for later inspection and improvement. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior...
