A four-page bill collation and coding equipment

Abstract

The invention discloses a four-part bill gathering and code printing device. The device comprises a conveying device 1, a tooth rolling device 2, a code printer 3, a paper collecting table 4 and a control system 5, wherein the conveying device 1 is provided with four feed inlets, a four-part bill is conveyed to the tooth rolling device 2 through the conveying device 1, the control system 5 controls the tooth rolling device 2 to conduct tooth rolling and gathering on the bill, the bill subjected to tooth rolling and gathering conducted by the tooth rolling device 2 is conveyed to the code printer 3, the control system 5 controls the code printer 3 to conduct code printing, and then the bill subjected to code printing conducted by the code printer 3 is collected through the paper collecting table 4 in a stacked mode. The device has the advantages that the code printing device is designed specially for the four-part bill, the conveying device enables the upper portion and the lower portion of the four-part bill to be aligned and has a tension control function, and therefore code printing quality is improved; it is only required to replace the code printer in the code printing device when code printing is conducted on bills in different specifications and sizes, and therefore replacement processes are simplified, replacement time is shortened and production efficiency is improved.

Description

technical field [0001] The invention relates to a coding device in the bill printing industry, and is especially suitable for coding the pages of quadruple bills with pre-punched holes on both sides. Background technique [0002] The bills that are generally used at present all adopt one type of multiple sheets to be stacked together (generally 3-5 sheets). Each sheet of each sheet has the same serial number, and the back of each sheet has a copying function. When coding multi-part bills (the code is the invoice number), it is necessary to align the upper and lower positions of each bill in order to ensure that the printed multi-part bills are neat and consistent. Otherwise, if the top and bottom of the bill are misaligned, it will cause the upper and lower coding of the printed multi-part bill to be misplaced, and the coding position will be shifted, etc., which will affect the use. Such as figure 1 is a schematic diagram of the face structure of the bill, where d is the ...

Problems solved by technology

[0004] However, the existing conveying device does not have the function of aligning and calibrating the bills up and down, so it is easy to cause misalignment or offset accumulation of multi-part bills during the conveying process, resulting in misalignment or offset of the bills that are getting closer to the back. It will eventually lead to the serious misalignment of the overall printing of the bills, which will affect the quality of the coding, cause waste, increase the production cost of the enterprise, and reduce the production efficiency of the enterprise; in addition, the existing transmission device does not have the ability to control the paper Tension adjustment function, the tension control of the paper has a great influence on the coding quality. If the tension is small, it will cause the paper to relax and easily make the alignment of each bill shift, thus affecting the coding quality. If the tension is large, Accidental force on the paper during conveying or coding can easily cause it to break and cause waste, thereby increasing the production cost of the enterprise and reducing the production efficiency of the enterprise

[0005] At the same time, for the existing coding device, the coding control method is pneumatic, and the coding unit and the coding control mechanism need to be replaced every time a paper of a specification is replaced, and pneumatic components and equipment need to be added, which makes the replacement process cumbersome. , The replacement time is long, which greatly reduces the production efficiency of the enterprise

At present, there is no coding equipment that is specially designed for quadruple bills and can solve the above problems
