Problems solved by technology

In the production process, first print the pattern of several small sheets on the large sheet according to a certain arrangement, and then print the number of each small sheet, and cut the printed large sheet into independent small sheets to form finished banknotes. Then count and package the individual finished banknotes to form packaged products and put them into the warehouse. In order to ensure that there are no waste bills in the warehoused products, the small waste bills must be detected and sorted out before counting and packaging, and the waste bills shall be sorted out according to the waste bills of the small bills. The number of the ticket is used to make up

Embodiment Construction

[0010] In the large-sheet detection and marking step, the large-sheet inspection machine can adopt the existing technology, and the inspection is performed on the large-sheet, which is beneficial to improve the detection efficiency. A colorless or colored fluorescent mark with an excitation wavelength of 430-470 nanometers is used as the invalid ticket mark. This invalid ticket mark is easy to be identified and detected by subsequent steps. The invalid ticket mark can also be a bar code or any other suitable form.

[0011] In the large-sheet waste counting step, the identification of the discarded ticket is performed on the large sheet. According to the specific invalid ticket marking method, the front and back sides of the large sheet are detected by a fluorescence detector or other corresponding detectors. Go to the small number of the invalid ticket mark and enter the code printing computer for information processing. The computer records the number of the invalid ticket for ve...

Abstract

A method for separating a defective piece of paper money from a complete page of paper money pieces in the procedure of printing paper money includes such steps as using a page checking machine to find out the defective piece of paper money from a complete page of paper money pieces on which the pattern has been printed, spraying fluorescent powder on it, detecting it by fluorescent detector, sending its serial number to number-printing computer, separating out the defective piece paper money, using a good one to replace it, and checking. Its advantages are high automation level and high correctness.

Description

Technical field [0001] The invention relates to the field of banknote printing production, in particular to a method for counting and sorting small scraps in banknote printing production. Background technique [0002] The waste counting and sorting of small scraps in the existing banknote printing production are realized by manual methods. In the production process, several small sheets are printed on the large sheet in a certain arrangement, and then the number of each small sheet is printed, and the printed large sheet is cut into individual small sheets to form a finished banknote. Then the single finished banknotes are counted and packaged to form packaged products and then put into the warehouse. In order to ensure that there are no discarded tickets in the warehoused products, the small discarded notes must be detected and sorted out before the count and package, and the discarded ones must In the prior art, the invalid ticket detection is performed before the number printi...
