Description

Automatic sorting method based on accounting document collator

Technical Field

The invention belongs to the technical field of automatic sequencing and sorting of accounting documents, and particularly relates to an automatic sequencing method based on an accounting document sorting machine.

Background

The financial account-posting comprises three steps: after the economic business of the first step takes place, the original bills such as receipts, invoices and the like related to the economic business are sent to the field of a financial department by a manager for account reporting, the accountants of the financial department perform classified processing on the original bills and input the processed bills into a computer accounting system to generate accounting documents, and the paper accounting documents are sorted, arranged and bound into books as accounting documents for keeping.

With the development and popularization of information technology, the cashless appointment account-reporting mode is gradually mature and widely applied, accounting documents are automatically generated by robot account-reporting, and the working efficiency of a financial department is greatly improved by the appearance of new technologies in the process of tightly routing and drum-packing. However, when the problem of the first two steps, namely the problem of queuing and posting on site, is solved, a robot is used for replacing manual work to automatically generate accounting documents, and the problem of accounting treatment is solved, namely the problem of how to sort out disordered documents in the third step is also expected to be solved. Because a large number of account-reporting reservation sheets need a plurality of people or a plurality of terminals to carry out accounting account processing, the plurality of people or the plurality of terminals simultaneously enter an accounting system to manufacture accounting documents, the system generates document sheet numbers according to the sequence of production documents, messy accounting documents without sequencing are naturally generated after the accounting system finishes the work of manufacturing the accounting documents, and the papery accounting documents are arranged according to the code size sequence according to the stipulation of the accounting law and are bound into a book to be consulted as accounting documents.

For a long time, the original manual operation stage, namely the manual sorting and document sorting method at the end of each day or month, is quite time-consuming and labor-consuming. After the reservation and account-reporting mode is implemented, the amount of the voucher is increased sharply, because the reservation persons do not have financial knowledge and do not have the capacity of classifying and sorting the reserved bills, most reservation persons can make one reservation sheet, and one reservation sheet can be made into an accounting voucher by a financial department. According to incomplete statistics, the accounting documents of units are increased by about 2-3 times after appointment and account reporting are carried out, for large enterprises and high institutions with large voucher amount at ordinary times, the increased voucher amount is more, 200-300 vouchers are generated every day, and 5000-7000 vouchers are generated every month, which are common things, so that an automatic sequencing method based on an accounting document collator is urgently needed in actual work, and manual operation is liberated.

step six, recovering the accounting documents corresponding to the unidentified accounting document single numbers: the accounting document (20) corresponding to the unidentified accounting document number falls into a terminal transmission belt (25) through the transmission of a transparent sorting belt (16), and then falls into a containing box (26) through the transmission of the terminal transmission belt (25);

step seven, regarding the next electric clamping jaw (23) as the first electric clamping jaw (23), and circulating the step four to the step six until the electric clamping jaw (23) completely clamps the accounting documents (20) corresponding to the single number in the interval of the accounting document single number to be identified, and stopping conveying the accounting documents (20);

the main controller (32) adjusts the chain transmission belt (22) through a second stepping motor, so that the N electric clamping jaws (23) are all positioned on the lower surface of the chain transmission belt (22);

step eight, emptying the containing box: taking out all accounting documents (20) corresponding to the unidentified accounting document numbers in the containing box (26);

step nine, automatic sequencing and binding of the accounting documents corresponding to the identified accounting document sheet numbers: sequencing the accounting document numbers from big to small according to a set interval of the accounting document numbers to be identified, wherein each accounting document number is respectively stored in a branch memory (40) in each electric clamping jaw control module (38), a main controller (32) is firstly communicated with the electric clamping jaw control module (38) corresponding to the largest accounting document number, a microcontroller (39) in the electric clamping jaw control module (38) corresponding to the largest accounting document number controls an electric clamping jaw (23) to be opened, so that the accounting document (20) corresponding to the largest accounting document number falls in a terminal transmission belt (25) and then falls in a containing box (26) through the transmission of the terminal transmission belt (25), and the process that the residual accounting documents (20) corresponding to the identified accounting document numbers fall in the containing box (26) is consistent with the process that the accounting document (20) corresponding to the largest accounting document number falls in the containing box (26), completing automatic sequencing of the accounting document (20) corresponding to the identified accounting document number, wherein the accounting document number of the accounting document (20) is right side up;

then taking the accounting document (20) corresponding to the identified accounting document number which is automatically sequenced out from the storage box (26) and binding into a book;

step ten, the step one to the step nine are circulated for multiple times until the automatic sequencing and binding of all the accounting documents (20) are completed.
