[0002] Currently, in the related art, processes of a paper cutting and packaging system such as paper feeding, counting, and sorting all require manual operation, and this cannot achieve a fully integrated production workflow, causes delays in quality information management, fails to conduct complete production information traceability and precise positioning of target paper, and lacks a production information verification procedure, leading to high digital security risks.SUMMARY

[0003] The present application aims to solve at least one of the technical problems existing in the prior art or the related art.

[0004] Thus, a first aspect of the present application provides a control method for a paper cutting and packaging system.

[0006] A third aspect of the present application provides a control apparatus for a paper cutting and packaging system.

[0007] A fourth aspect of the present application provides a computer-readable storage medium.

[0008] In view of this, the first aspect of the present application provides a control method for a paper cutting and packaging system, and the paper cutting and packaging system provided by the present application comprises a paper conveying mechanism, a paper feeding mechanism, a cutter detection mechanism, a cutting mechanism, a sorting mechanism, and a band detection mechanism; the paper conveying mechanism is configured to transport initial paper products. The control method comprises: acquiring first expected paper information of initial paper products; controlling the paper feeding mechanism to divide the initial paper products into a plurality of groups, wherein any group comprises P paper layers, and the first expected paper information comprises the paper information of the first sheet of paper of any group; controlling the paper feeding mechanism to acquire the paper information of the first paper layer in any group to obtain first paper information; verifying the first paper information against the first expected paper information; on the basis of the matching of the first paper information and the first expected paper information, controlling the paper feeding mechanism to operate; on the basis that the groups are located at the cutting mechanism, controlling the cutter detection mechanism to identify the paper information of the first paper layer of any group; acquiring second paper information; acquiring position parameters of the groups on the basis of the second paper information; on the basis that the position parameters are within a set range, controlling the cutting mechanism to cut the groups into a plurality of first paper groups; controlling the cutting mechanism to divide the first paper groups into a plurality of pieces of single-layer paper; acquiring second expected paper information on the basis of the paper information in the single-layer paper; and controlling a sorting mechanism to send the second expected paper information to a band detection mechanism, wherein the band detection mechanism is configured to identify the second expected paper information.

[0009] In the technical solution, the paper cutting and packaging system is a production device for paper. The paper cutting and packaging system comprises the paper conveying mechanism, the paper feeding mechanism, the cutter detection mechanism, the cutting mechanism, the sorting mechanism, a delivering mechanism and the band detection mechanism; the paper conveying mechanism is configured to transport initial paper products. Specifically, the initial paper products may be 10,000 paper layers, and a plurality of pieces of single-layer paper can be obtained after cutting each paper layer. Exemplarily, each paper layer comprises 5×7 pieces of single-layer paper, and the single-layer paper may be a banknote or voucher.

[0010] The first expected paper information of the initial paper products is acquired, and the first expected paper information refers to paper information expected to appear in a verification process of the subsequent paper feeding mechanism. By verifying specified paper information against the first expected paper information, whether the process is in normal operation can be determined. The paper feeding mechanism divides the initial paper products into a plurality of groups, and any group comprises P paper layers, and each group comprises 100 paper layers. The first expected paper information comprises the paper information of the first sheet of paper of any group. Exemplarily, the first expected paper information refers to 35 banknote numbers or voucher numbers contained in the expected specified paper layer.

[0011] The initial paper products are automatically transferred to the paper feeding mechanism in an automatic cutting production line by an AGV (Automatic Guided Vehicle). The paper feeding mechanism comprises an automatic paper feeding and hundred-sheet dividing module, which is composed of an image acquisition system, a backend industrial computer and a human-machine interactive touchscreen. The automatic paper feeding and hundred-sheet dividing module can realize identification and verification of the paper information, involving batch number addition and management, modeling, historical record management, etc. The paper feeding mechanism organizes and automatically counts the initial paper products through a paper vibrating machine and an initial paper product counter.

[0012] In the case that the groups rise to a specified position, the paper feeding mechanism acquires the paper information of the first paper layer in any group. Specifically, the automatic paper feeding and hundred-sheet dividing module acquires an image of the group and performs preprocessing such as template matching, ROI (Region of Interest) extraction, enhancement, and denoising on the acquired image. The ROI image is sent to a software system, for example, the software system can be Paddle, and number recognition is performed via OCR (Optical Character Recognition) to obtain the first paper information. The first paper information refers to the paper information of the topmost paper layer of the group in the paper feeding mechanism. Exemplarily, the first paper information refers to 35 banknote numbers or voucher numbers contained in the first paper layer of the group obtained by the paper feeding mechanism through number recognition.

[0013] The paper feeding mechanism verifies the first paper information against the first expected paper information. In the case that the first paper information matches the first expected paper information, that is, the verification of the groups in the paper feeding mechanism is qualified, a signal of normal verification is output to control the paper feeding mechanism to operate. In the case that the verification by the software system through a number recognition result of the OCR shows mismatching, for example, the software system can be Paddle, OCR is performed through the software system and then number recognition is performed again, for example, the software system can be HALCON, and the recognition result is verified. On the basis that the verification is qualified, a signal of normal verification is output to control the paper feeding mechanism to operate and convey the groups passing verification to the cutting mechanism; on the basis that the verification fails, a signal of abnormal verification is output, and the cause of abnormality is checked manually. The paper feeding mechanism ensures the correctness of the groups at the paper feeding mechanism by verifying the first paper information.

[0014] In the case that the groups are located at the cutting mechanism and a pressing plate of the cutting mechanism presses down to a specified position, the cutter detection mechanism identifies the paper information of the first paper layer of any group. Specifically, the cutter detection mechanism acquires an image of the group and performs preprocessing such as template matching, ROI extraction, enhancement, and denoising on the acquired image. The ROI image is conveyed to the software system and subjected to number recognition via OCR, to obtain the second paper information. The second paper information refers to the paper information of the topmost paper layer of the group in the cutting mechanism. Exemplarily, the second paper information refers to 35 banknote numbers or voucher numbers contained in the first paper layer of the group obtained by the cutter detection mechanism through number recognition.

[0015] The position parameters of the groups are acquired based on the second paper information, and the cutter detection mechanism acquires the position parameters of the groups. In the case that the position parameters are within a set range, the groups are properly positioned, the cutting mechanism cuts the groups into a plurality of first paper groups, and the cutting mechanism cuts each paper layer into a plurality of pieces of single-layer paper. Exemplarily, the first paper group is 100 single banknotes or vouchers after cutting, and the cutting mechanism cuts 100 paper layers into 35 first paper groups.

[0016] The cutting mechanism divides the first paper groups into a plurality of pieces of single-layer paper. The first paper group after cutting refers to a stacked state of a plurality of pieces of single-layer paper, and the cutting mechanism flattens the stacked single-layer paper on a conveyor belt of the delivering mechanism through a robotic arm. Exemplarily, the delivering mechanism may be a delivering belt, which can deliver the paper. The second expected paper information is acquired based on the paper information in the single-layer paper, and the second expected paper information refers to the paper information of target paper that passes the sorting. The sorting mechanism sends the second expected paper information to the band detection mechanism, and the second expected paper information is the paper information expected to appear in a subsequent band detection process. Exemplarily, the second expected paper information refers to a single banknote number or voucher number expected to appear in the subsequent band detection process.

[0017] The sorting mechanism is controlled to send the second expected paper information to the band detection mechanism, and the band detection mechanism is configured to identify the second expected paper information.

[0018] Thus, the control method for a paper cutting and packaging system reduces manual operation. Through a fully integrated production line, production processes such as paper feeding, counting, cutting, sorting, and thousand-sheet bundling are integrated, and a complete information system is constructed, thus solving the problems of quality information management and production information traceability, realizing precise positioning of the target paper and full-process production information traceability, and reducing digital security risks based on the verification of the paper information.

[0031] In the embodiment, the paper cutting and packaging system is a production device for paper. The paper cutting and packaging system comprises the paper conveying mechanism, the paper feeding mechanism, the cutter detection mechanism, the cutting mechanism, the sorting mechanism, a delivering mechanism and the band detection mechanism; the paper conveying mechanism is configured to transport the initial paper products. Specifically, the initial paper products may be 10,000 paper layers, and a plurality of pieces of single-layer paper can be obtained after cutting each paper layer. Exemplarily, each paper layer comprises 5×7 pieces of single-layer paper, and the single-layer paper may be a banknote or voucher.

[0032] The first expected paper information of the initial paper products is acquired, and the first expected paper information refers to the paper information expected to appear in a verification process of the subsequent paper feeding mechanism. By verifying specified paper information against the first expected paper information, whether the process is in normal operation can be determined. The paper feeding mechanism divides the initial paper products into a plurality of groups, and any group comprises P paper layers. Exemplarily, P can be 100, and each group comprises 100 paper layers. The first expected paper information comprises the paper information of the first sheet of paper of any group. Exemplarily, the first expected paper information refers to 35 banknote numbers or voucher numbers contained in the expected specified paper layer.

[0033] The initial paper products are automatically transferred to the paper feeding mechanism in an automatic cutting production line by an AGV (Automatic Guided Vehicle). The paper feeding mechanism comprises an automatic paper feeding and hundred-sheet dividing module, which is composed of an image acquisition system, a backend industrial computer and a human-machine interactive touchscreen. The automatic paper feeding and hundred-sheet dividing module can realize identification and verification of the paper information, involving batch number addition and management, modeling, historical record management, etc. As shown in Fig. 4, the paper feeding mechanism organizes and automatically counts the initial paper products through a paper vibrating machine and an initial paper product counter.

[0034] In the case that the groups rise to a specified position, the paper feeding mechanism acquires the paper information of the first paper layer in any group. Specifically, the automatic paper feeding and hundred-sheet dividing module acquires an image of the group and performs preprocessing such as template matching, ROI (Region of Interest) extraction, enhancement, and denoising on the acquired image. The ROI image is sent to a software system, for example, the software system can be Paddle, and number recognition is performed via OCR (Optical Character Recognition) to obtain the first paper information. The first paper information refers to the paper information of the topmost paper layer of the group in the paper feeding mechanism. Exemplarily, the first paper information refers to 35 banknote numbers or voucher numbers contained in the first paper layer of the group obtained by the paper feeding mechanism through number recognition.

[0035] The paper feeding mechanism verifies the first paper information against the first expected paper information. In the case that the first paper information matches the first expected paper information, that is, the verification of the groups at the paper feeding mechanism is qualified, a signal of normal verification is output to control the paper feeding mechanism to operate. In the case that the verification by the software system through a number recognition result of the OCR shows mismatching, for example, the software system can be Paddle, OCR is performed through the software system and then number recognition is performed again, for example, the software system can be HALCON, and the recognition result is verified. On the basis that the verification is qualified, a signal of normal verification is output to control the paper feeding mechanism to operate and convey the groups passing verification to the cutting mechanism; on the basis that the verification fails, a signal of abnormal verification is output, and the cause of the abnormality is checked manually. The paper feeding mechanism ensures the correctness of the groups at the paper feeding mechanism by verifying the first paper information.

[0036] A current grouping count is recorded after each successful verification of the paper feeding mechanism, and the previous grouping count is increased by 1 in the case that verification is required next time.

[0037] The cutter detection mechanism is located at a cutting blade of the cutting mechanism and consists of an image acquisition system, a backend industrial computer, and a human-machine interactive touchscreen. It can perform paper information identification, verification, tilt detection and side gauge detection on any group of the cutting mechanism, involving batch number addition and management, modeling, historical record management, etc. Through PLC control, the cutter detection mechanism realizes signal interaction with the cutting apparatus.

[0038] In the case that the groups are located at the cutting mechanism and a pressing plate of the cutting mechanism presses down to a specified position, the cutter detection mechanism identifies the paper information of the first paper layer of any group. Specifically, the cutter detection mechanism acquires the image of the group and performs preprocessing such as template matching, ROI extraction, enhancement, and denoising on the acquired image. The ROI image is conveyed to the software system and subjected to number recognition via OCR, to obtain the second paper information. The second paper information refers to the paper information of the topmost paper layer of the groups at the cutting mechanism. Exemplarily, the second paper information refers to 35 banknote numbers or voucher numbers contained in the first paper layer of the group obtained by the cutter detection mechanism through number recognition.

[0039] The position parameters of the groups are acquired based on the second paper information, and the cutter detection mechanism acquires the position parameters of the groups. In the case that the position parameters are within a set range, the groups are properly positioned, the cutting mechanism cuts the groups into a plurality of first paper groups, and the cutting mechanism cuts each paper layer into a plurality of pieces of single-layer paper. Exemplarily, the first paper group is 100 single banknotes or vouchers after cutting, and the cutting mechanism cuts 100 paper layers into 35 first paper groups.

[0040] A current cutting count is recorded after each successful verification of the cutter detection mechanism, and the previous cutting count is increased by 1 in the case that verification is required next time.

[0041] In the case that the paper layers are replaced or supplemented, the paper feeding mechanism acquires relevant information of replaced or supplemented paper layers. Exemplarily, the relevant information comprises the original number, the original position minor number, the supplementary ticket number, and the supplementary ticket number difference of relevant paper layers. The system searches for a corresponding record in a database table based on the original number and original position minor number, replaces the original paper information of the paper layer through the supplementary ticket number and the supplementary ticket number difference, and records the corresponding information of the original number and the supplementary ticket number in a supplementary ticket table. The cutter detection system acquires the corresponding information in a database based on the grouping count of the paper feeding mechanism, and verifies the identified paper information against the corresponding information, and the verification succeeds if they match and fails if they do not match.

[0042] The cutting mechanism divides the first paper group into a plurality of pieces of single-layer paper. The first paper group after cutting refers to a stacked state of a plurality of pieces of single-layer paper, and the cutting mechanism flattens the stacked single-layer paper on a conveyor belt of the delivering mechanism through a robotic arm. Exemplarily, the delivering mechanism may be a delivering belt, which can deliver the paper.

[0043] The second expected paper information is acquired based on the paper information in the single-layer paper, and the second expected paper information refers to the paper information of the target paper that passes the sorting. The sorting mechanism sends the second expected paper information to the band detection mechanism, and the second expected paper information is the paper information expected to appear in a subsequent band detection process. Exemplarily, the second expected paper information refers to a single banknote number or voucher number expected to appear in the subsequent band detection process.

[0044] The sorting mechanism is controlled to send the second expected paper information to the band detection mechanism, and the band detection mechanism is configured to identify the second expected paper information.

[0045] As shown in Fig. 3, the system adopts an intelligent analysis technology based on AI (Artificial Intelligence), and realizes stable and highly efficient operation of the integrated process through an architecture of edge collection plus centralized computing, various OCR recognition, and intelligent detection accuracy. Files are shared between a server and a client through the system framework of a RPC (Remote Procedure Calls, an open-source remote procedure call system), for example, the files can be proto, effectively reducing the load and improving serialization speed. A computing station adopts multi-station backup equipped with a GPU (Graphics Processing Unit), and provides computing support for each detection station through a computer network. A detection station sends the image to the computing station which feeds back a result through computation. An entire data center involves data reports of various processes. Through the close integration of the internal data structure, OCR data structure, and QR code system of the sorting mechanism, supporting development and data integration are realized, enabling the sorting mechanism to adapt to special working modes such as re-circulation of all products, all qualified products and some qualified products on the sorting mechanism after boxing is completed.

[0046] Thus, the control method for a paper cutting and packaging system reduces manual operation. Through a fully integrated production line, production processes such as paper feeding, counting, cutting, sorting and thousand-sheet bundling are integrated, and a complete information system is constructed, thus solving the problems of quality information management and production information traceability, realizing precise positioning of the target paper and full-process production information traceability, and reducing digital security risks based on the verification of the paper information.

[0047] In addition, the control method for a paper cutting and packaging system in the above embodiments provided by the present application can further comprise the following additional technical features.

[0048] In some embodiments provided by the present application, the control method for a paper cutting and packaging system provided by the present application further comprises: controlling the cutter detection mechanism to verify at least one of the first paper information and the first expected paper information against the second paper information; acquiring the position parameters of the groups based on the matching of the first paper information and the second paper information, or the matching of the first expected paper information and the second paper information.

[0049] In the embodiment, the cutter detection mechanism verifies at least one of the first paper information and the first expected paper information against the second paper information; the cutter detection mechanism sends a release signal based on the matching of the first paper information and the second paper information, or the matching of the first expected paper information and the second paper information, i.e., the verification result of the second paper information is qualified. In the case that the verification result is unqualified, the cutter detection mechanism sends an alarm and cutting stop signal. By verifying the second paper information, the cutter detection mechanism ensures the correctness of the groups to be cut.

[0050] In some embodiments provided by the present application, the control method for a paper cutting and packaging system provided by the present application further comprises: controlling the delivering mechanism to deliver a plurality of pieces of single-layer paper to the sorting mechanism; controlling the sorting mechanism to identify the paper information in the plurality of pieces of single-layer paper; acquiring third paper information; controlling the sorting mechanism to sort a plurality of pieces of single-layer paper to obtain the target paper, wherein, the plurality of pieces of single-layer paper comprise the target paper; and acquiring second expected paper information based on the third paper information of the target paper.

[0051] In the embodiment, the delivering mechanism delivers a plurality of pieces of single-layer paper to the sorting mechanism, facilitating verifying and sorting the single-layer paper one by one in subsequent processes. Specifically, the paper cutting and packaging system can comprise a plurality of sorting mechanisms. Exemplarily, the paper cutting and packaging system can comprise 2 sorting mechanisms, and the delivering mechanism delivers a plurality of pieces of single-layer paper to the sorting mechanisms in an idle state.

[0052] Specifically, when one sorting mechanism breaks down and cannot continue working, the paper is manually transferred to the trolley of the other sorting mechanism, and the image of the paper is acquired through a manual photographing mode. Based on shunt table data and the state of the database after the faulty sorting mechanism is isolated, comprehensive comparison is carried out to determine that the paper has been produced by other sorting mechanisms. Through prompting and confirmation, the data is updated to the corresponding data of the sorting mechanism in a working state, to realize the transfer of data and paper.

[0053] It needs to be noted that, as shown in Fig. 5, the paper information identification processes before and after the two sorting mechanisms and a band station all require two-way data access with the sorting mechanisms. However, the two sorting mechanisms both use the same IP address segment and cannot directly access to the same switch, otherwise an IP address conflict between the two sorting mechanisms will be incurred. A method of the combination of port forwarding plus multi-gateway plus setting network hop is adopted to realize mutual access to the databases of the two sorting mechanism devices.

[0054] The sorting mechanism acquires the image of the single-layer paper, identifies the paper information in a plurality of pieces of the single-layer paper, and performs number recognition on the image to obtain the third paper information. The third paper information refers to the paper information of the single-layer paper entering the sorting mechanism obtained through number recognition. Exemplarily, the third paper information is the number of a single banknote or voucher acquired by the sorting mechanism through number recognition.

[0055] The sorting mechanism sorts a plurality of pieces of single-layer paper, the image quality of the single-layer paper is verified for the image of the single-layer paper acquired by the sorting mechanism, the single-layer paper which is unqualified after the sorting and verification become waste products and is subjected to online waste product destruction, and the single-layer paper which is qualified after the sorting and verification is used as the target paper and is output from the sorting mechanism, to obtain the target paper with qualified quality. A plurality of pieces of single-layer paper comprises the target paper, and the target paper is the single-layer paper that is qualified after the sorting. Exemplarily, the target paper is a finished banknote or voucher.

[0056] The second expected paper information is acquired based on the third paper information of the target paper. Specifically, the third paper information is compared with all possible batches of sub-tables in the database of the sorting mechanism in a current shift, the machine number of the current third paper information is found, and then the first M pieces of third paper information that have been deduplicated and belong to a target paper bin are acquired from data greater than the current machine number and used as the second expected paper information.

[0057] In some embodiments provided by the present application, the control method for a paper cutting and packaging system provided by the present application further comprises: controlling the sorting mechanism to bundle the target paper into a plurality of second paper groups through a band, any second paper group comprises M pieces of target paper, and the second expected paper information comprises the third paper information of the target paper of any second paper group; controlling the sorting mechanism to add a barcode label to the band, wherein the barcode label comprises the second expected paper information.

[0058] In the embodiment, the sorting mechanism bundles the target paper into a plurality of second paper groups through a band, for the convenience of subsequent boxing. Any second paper group comprises M pieces of target paper, and the second expected paper information comprises the third paper information of the target paper of any second paper group. Exemplarily, M can be 1000, and any second paper group comprises 1000 banknotes or vouchers. The second expected paper information is the numbers of the 1000 banknotes or vouchers.

[0059] The sorting mechanism is controlled to add a barcode label to the band, wherein the barcode label comprises the second expected paper information. The second expected paper information can be acquired by scanning the barcode label, and information such as verification date, personnel, machine and serial number can further be acquired.

[0060] Specifically, the band detection mechanism is located in a rear end process of the sorting mechanism, with a quantity consistent with that of the sorting mechanism, and consists of an image acquisition system, a backend industrial computer, and a human-machine interactive touchscreen, and realizes paper information identification, verification and barcode detection of sorted products, involving batch number addition and management, modeling, historical record management, etc. The band detection mechanism is controlled through a PLC, achieves signal interaction with a GTS counting module and a band device, etc., and executes corresponding actions. After receiving a paper information module in-place signal and a band module in-place signal of the second paper groups, the band detection mechanism can output signals such as normal paper information verification, a GTS counting result, normal barcode detection, normal white strip separation detection, and abnormal detection.

[0061] In some embodiments provided by the present application, the control method for a paper cutting and packaging system provided by the present application further comprises: acquiring the batch number information of the paper conveying mechanism, wherein the batch number information is associated with the paper information of the initial paper products; and acquiring the quantity, the quantity of expected groups, and the paper information of the initial paper products, and determining the first expected paper information of the first sheet of paper in any expected group based on the quantity, the quantity of the expected groups, and the paper information of the initial paper products.

[0062] In the embodiment, the relevant information of the initial paper products conveyed by the paper conveying mechanism is manually input into a database. Exemplarily, the initial paper products are 10,000 uncut large-sheet banknotes or vouchers. A transporting mechanism transports the initial paper products to the paper feeding mechanism by a transporting vehicle, wherein, the transporting vehicle comprises batch number information, exemplarily, the batch number information is the number of the transporting vehicle. The batch number information of the paper conveying mechanism is acquired, and the batch number information is associated with the paper information of the initial paper products, exemplarily, the batch number information comprises the number of the paper transporting vehicle in any process. The quantity, the quantity of the expected groups, and the paper information of the initial paper products are input into the database, then the paper information of all single-layer paper is calculated based on the quantity, the quantity of the expected groups, and the paper information of the initial paper products, and the paper information of the first sheet of paper of any group expected to appear in subsequent processes is determined. This is configured to verify whether the groups of the paper feeding mechanism is correct, and improves production information records in the production system.

[0063] Specifically, a detection process automatically acquires corresponding expected paper information based on the paper information generated by a previous station, realizing automatic detection of the entire integrated production line. Operators only need to input the paper information at the paper feeding mechanism or the cutter detection mechanism, and subsequent stations can automatically start detection based on the batch number information of the previous station, thus avoiding inputting data sequentially at each station during operation.

[0064] Thus, based on the relevant information of the initial paper products, the paper information of the first sheet of paper of any group expected to appear in subsequent processes is determined, which improves the production information recording in the production system.

[0065] In some embodiments provided by the present application, as shown in Fig. 3 and Fig. 4, the paper cutting and packaging system provided by the present application comprises a verification mechanism, and the control method for a paper cutting and packaging system further comprises: acquiring third expected paper information; controlling the cutting mechanism to combine N first paper groups into a third paper group, wherein the third expected paper information comprises the paper information of the first sheet of paper of any third paper group; controlling the verification mechanism to identify the paper information of the first sheet of paper of any third paper group, and acquiring fourth paper information; and verifying the fourth paper information against the third expected paper information; controlling the delivering mechanism to divide a plurality of third paper groups into a plurality of pieces of single-layer paper, based on the matching of the fourth paper information and the third expected paper information.

[0066] In the embodiment, based on the input relevant information of the initial paper products, the paper information of all target paper is calculated, and the third expected paper information is acquired. The third expected paper information refers to the paper information expected to appear in the verification process of the subsequent verification mechanism. Exemplarily, the third expected paper information is the banknote number or voucher number of the first paper layer of the third paper group expected to appear in the verification process. By verifying specified paper information against the third expected paper information, whether the process is in normal operation can be determined. Exemplarily, the third expected paper information can be the number of the first banknote or voucher of the third paper group entering the sorting mechanism.

[0067] The cutting mechanism is controlled to combine N first paper groups into the third paper group, and the third paper group is formed by stacking N first paper groups. The third expected paper information comprises the paper information of the first sheet of paper of any third paper group. Exemplarily, N can be 10, and 10 first paper groups are stacked to form a third paper group. Each third paper group comprises 1000 pieces of single-layer paper, and the third expected paper information is the banknote number or voucher number of the topmost single-layer paper among the 1000 pieces of single-layer paper.

[0068] Specifically, the number of verification mechanisms is consistent with that of sorting mechanism. The verification mechanism is located at a paper feeding position at the front end of the sorting mechanism, is controlled by the image acquisition system through a PLC, and realizes signal interaction with a cutting line and the sorting mechanism and executes corresponding actions. After receiving a manipulator in-place signal, the verification mechanism can output a verification signal, and the verification results comprise readiness, acquisition completion, normal verification, abnormal verification, in-machine trolley release, and out-of-machine trolley release.

[0069] The verification mechanism mainly realizes the identification and verification of the paper information of the target paper to be entering the sorting mechanism, involving batch number management, transfer management, historical record management, etc. The verification mechanism can index historical data query and track based on conditions such as batch number, time period and machine number, realize data transfer between two sorting mechanisms, and achieve automatic batch number activation and automatic batch number replacement. It automatically acquires the shunt data of the sorting mechanism and the cutting mechanism, and realizes automatic activation and continuous production. The verification mechanism can also exchange relevant database information with the cutting mechanism and the sorting mechanism, and exchange data such as batch number information, supplementary ticket information, paper information and expected paper information. It verifies and records the date of an expected number shunt table of the cutting line, a database table of the sorting mechanism, a local record table, etc.

[0070] Specifically, after the cutting mechanism combines N first paper groups into the third paper group, seven third paper groups are loaded at one time by the trolley on a link and pushed to the sorting mechanism. After the pushing is successful, in a database production code table, the state of the sorting mechanism identification field of the seven third paper groups is updated to a production line number of the corresponding sorting mechanism. Exemplarily, a first production line is numbered 1, and a second production line is numbered 2.

[0071] The verification mechanism acquires images of the third paper groups, identifies the paper information of the first sheet of paper of any third paper group, and obtains fourth paper information. The fourth paper information refers to the paper information of the topmost paper layer in the third paper group at the verification mechanism. Exemplarily, the fourth paper information is the number of the topmost banknote or voucher of the third paper group identified by the verification mechanism. The fourth paper information is verified against the third expected paper information. In the case that the fourth paper information matches the third expected paper information, that is, the verification is passed, the verification mechanism verifies the fourth paper information to ensure the correctness of the third paper groups to be delivered. In addition, the cutting mechanism combines N first paper groups into the third paper group through a strip cutting station, a strip collecting station, and a thousand-sheet collecting station, to improve the verification efficiency of the verification mechanism.

[0072] The delivering mechanism is controlled to divide a plurality of third paper groups into a plurality of pieces of single-layer paper, which are flattened on the delivering mechanism to facilitate verifying and sorting the single-layer paper in subsequent processes.

[0073] Thus, the cutting mechanism combines N first paper groups into the third paper group, which improves the verification efficiency of the verification mechanism. By verifying whether the fourth paper information matches the third expected paper information, the correctness of the third paper groups to be delivered is ensured.

[0074] In some embodiments provided by the present application, as shown in Fig. 3, the control method for a paper cutting and packaging system provided by the present application further comprises: acquiring fourth expected paper information of the single-layer paper, wherein the fourth expected paper information comprises the paper information of any single-layer paper; controlling the verification mechanism to send the fourth expected paper information to the sorting mechanism; controlling the sorting mechanism to verify the third paper information against the fourth expected paper information; and controlling the sorting mechanism to sort the single-layer paper based on the matching of the third paper information and the fourth expected paper information.

[0075] In the embodiment, the fourth expected paper information of the single-layer paper is acquired, and the fourth expected paper information comprises the paper information of any single-layer paper. Exemplarily, the fourth expected paper information can be the banknote number or voucher number expected to appear in the sorting process.

[0076] Specifically, the verification mechanism can also send information corresponding to the third paper group such as the batch number and product state to a real-time analysis and control system in the sorting mechanism to perform serialization preparation for the sorting mechanism. When the verification mechanism verifies the third paper group, the state of the single-layer paper included in the third paper group is "to be produced", and the state of the single-layer paper is reset to "produced" after the completion of sorting. The interaction among several states is achieved through a state field.

[0077] The verification mechanism is controlled to send the fourth expected paper information to the sorting mechanism, and the sorting mechanism is controlled to verify the third paper information against the fourth expected paper information. In the case that the third paper information matches the fourth expected paper information, that is, the verification is qualified, the sorting mechanism is controlled to sort the single-layer paper. The verification mechanism verifies the third paper information to ensure the correctness of the single-layer paper to be sorted.

[0078] Thus, by verifying whether the third paper information matches the fourth expected paper information, the correctness of the single-layer paper to be sorted is ensured.

[0079] In some embodiments provided by the present application, the position parameters comprise a first position parameter, a second position parameter, and a third position parameter. The first position parameter comprises an offset value of the cutter detection mechanism relative to a first direction coordinate. The second position parameter comprises a first relative position parameter of the group and the cutter detection mechanism in a second direction. The third position parameter comprises a second relative position parameter of the group and the cutter detection mechanism in a third direction. The control method for a paper cutting and packaging system provided by the present application further comprises: controlling the cutter detection mechanism to acquire the position information of the group, and determining the first position parameter, the second position parameter, and the third position parameter based on the position information; and the first position parameter is within a parameter threshold range, the second position parameter is less than or equal to a first parameter threshold, and the third position parameter is less than or equal to a second parameter threshold.

[0080] In the embodiment, the cutter detection mechanism identifies the ROI image of the group, performs automatic threshold segmentation on the ROI image, and conducts morphological filtering to remove interference such as dirt, and acquires the position information of the groups located at the cutting mechanism. As shown in Fig. 2, the cutting mechanism in the automatic cutting production line comprises cutting blades, specifically, the cutting blades comprise a cutting blade A and a cutting blade B.

[0081] The cutter detection mechanism performs B-blade side gauge detection on the group entering the cutting mechanism, and determines the first position parameter based on the position information. Exemplarily, Hough line search is performed on the interference-removed image, and the searched straight lines are drawn on a new blank image. The searched straight lines are sorted based on a Y-direction coordinate, and the first direction coordinate is acquired based on the first straight line in the Y direction. The first position parameter is an offset value calculated based on first direction coordinate information, and the offset value is sent to the cutting mechanism. In the case that the first position parameter is within the parameter threshold range, the B-blade side gauge detection is normal, and a signal of normal B-blade detection is output. In the case that the first position parameter is outside the parameter threshold range, the cutter detection mechanism sends a B-blade side gauge alarm and shutdown signal to the cutting mechanism, and the cutting blades A and B of the cutting mechanism both stop descending. The B-blade side gauge detection ensures that the distance between the group located at the cutting mechanism and the cutting blades is within an allowable range.

[0082] The cutter detection mechanism performs AB blade tilt detection on the group entering the cutting mechanism. For the AB blade tilt detection, a diagonal intaglio pattern is captured for positioning. In the case that the pressing plate reaches a specified position, the second position parameter and the third position parameter are calculated based on the positioning result of the diagonal intaglio. The second position parameter comprises the first relative position parameter of the group and the cutter detection mechanism in the second direction, and the third position parameter comprises the second relative position parameter of the group and the cutter detection mechanism in the third direction. Exemplarily, the second position parameter can be an offset value of the positioning of the diagonal intaglio in an X direction, and the third position parameter can be an offset value of the positioning of the diagonal intaglio in the Y direction. In the case that the second position parameter is less than or equal to the first parameter threshold and the third position parameter is less than or equal to the second parameter threshold, the AB blade tilt detection is normal, and a signal of normal AB blade tilt detection is output. In the case that the second position parameter is greater than the first parameter threshold or the third position parameter is greater than the second parameter threshold, the cutter detection mechanism sends a tilt detection alarm and shutdown signal. The AB blade tilt detection ensures that the tilt angle of the group placed at the cutting mechanism is within an allowable range.

[0083] Thus, since the first position parameter is within the parameter threshold range, the second position parameter is less than or equal to the first parameter threshold, and the third position parameter is less than or equal to the second parameter threshold, it is guaranteed that both the distance between the group located at the cutting mechanism and the cutting blades, and the tilt angle of the group placement are within an allowable range.

[0084] In some embodiments provided by the present application, as shown in Fig. 4, the control method for a paper cutting and packaging system provided by the present application further comprises: bundling E pieces of the target paper into a fourth paper group through a bundling strip; and bundling F fourth paper groups into a second paper group through a band.

[0085] In the embodiment, after the target paper passes the sorting area of the sorting mechanism and the paper outlet of the sorting mechanism, the E pieces of the target paper are bundled into the fourth paper group through the bundling strip, and the F fourth paper groups are bundled into the second paper group through the band. Any fourth paper group comprises E pieces of the target paper, and any second paper group comprises E×F pieces of the target paper. Exemplarily, E can be 100 and F can be 10. After the bundling, any fourth paper group comprises 100 pieces of the target paper, and any second paper group comprises 10 fourth paper groups, i.e., comprising 1000 pieces of the target paper.

[0086] Thus, grouping and bundling the target paper facilitates the counting, boxing, and transportation of the target paper.

[0087] In some embodiments provided by the present application, as shown in Fig. 3 and Fig. 4, the control method for a paper cutting and packaging system provided by the present application further comprises: controlling the band detection mechanism to identify the paper information of the first sheet of paper of any second paper group in a plurality of second paper groups to obtain fifth paper information; controlling the band detection mechanism to acquire a bundling image of the bundling strip; controlling the band detection mechanism to verify the fifth paper information against the second expected paper information to obtain a first verification result; acquiring a barcode image of the barcode label, and comparing the barcode image with a first preset image to obtain a second verification result; comparing the bundling image with a second preset image to obtain a third verification result; and performing plastic sealing packaging on the second paper group based on the first verification result, the second verification result, and the third verification result.

[0088] In the embodiment, the band detection mechanism acquires images of the second paper groups, identifies the paper information of the first sheet of paper of any second paper group in a plurality of second paper groups, and obtains the fifth paper information, and the fifth paper information refers to the paper information of the first sheet of paper of the second paper group after bundling with the band. Exemplarily, the fifth paper information is the number of the first banknote or voucher of the second paper group identified by the band detection mechanism. The band detection mechanism acquires the bundling image of the bundling strip and acquires the bundling state of the second paper group based on the bundling image.

[0089] The band detection mechanism verifies the fifth paper information against the second expected paper information and obtains the first verification result, and determines whether the fifth paper information matches the second expected paper information through the first verification result, to ensure the correctness of the bundled second paper group.

[0090] Specifically, all possible batch number information of the second paper group is acquired through current train information, and then all possible batch information is acquired by querying the database of the sorting mechanism. When the second paper group passes a detection point, through acquiring the paper information of the first sheet of paper of the second paper group and the second expected paper information, the sub-table data of all possible batch information and current batch information are compared to determine whether the paper information belongs to the current batch, if not, the next batch is continuously queried until the comparison is successful. Since the database of the sorting mechanism contains the associated information of the batch number information and the batch information, the batch number information of a current second paper group can be obtained through the batch information of the sorting mechanism.

[0091] The band detection mechanism acquires the barcode image of the barcode label and compares the barcode image with the first preset image, and obtains the second verification result. The first preset image can be a barcode label image template pre-stored in the database. The second verification result ensures that the image of the barcode label is clear and qualified. The band detection mechanism determines the position of the barcode image through template positioning, performs rotation correction to identify one-dimensional code information, recognizes the alphanumeric information below the barcode image through deep learning, determines the integrity of the lines by searching for the lines of the barcode image, and conducts barcode quality detection.

[0092] The bundling image is compared with the second preset image to obtain the third verification result. The first preset image can be a bundling image template pre-stored in the database. The third verification result ensures that the bundling of the target paper is qualified. Exemplarily, target recognition of the bundling strip is performed through deep learning technology, and whether the number of bundling strips is 10 is determined. Based on the position information of the bundling strips, the bundling strips are divided into two groups, in which five bundling strips are at an upper position and five bundling strips are at a lower position, and then the neatness of the bundling strips is determined.

[0093] In the case that the first verification result, the second verification result, and the third verification result are all qualified, the second paper group is subjected to plastic sealing packaging by a thermal sealing machine, and is conveyed to the boxing mechanism through an automatic conveyor belt after counting.

[0094] It should be noted that the band detection mechanism performs bundling strip detection, paper information recognition, and barcode label graphic quality detection through deep learning technology. A deep learning network uses a large data sample set for network training. In a deep learning training phase, the sample data is compared with the result of manually marked data through a predicted result of the deep learning network, and comparison differences are fed back to the deep learning network. The network continuously adjusts network parameters to continuously resolve and reduce the differences between the predicted result of the network and the manual mark, to achieve analysis results close to manual ones. Deep learning is for neatness and quantity detection of bundling strips and for number recognition of barcode labels; template matching is for QR code quality inspection; template positioning and deep learning are for paper information recognition to avoid human errors.

[0095] Thus, by verifying the fifth paper information, the barcode image and the bundling image, it is ensured that the bundled second paper group is correct, the barcode image is clear and qualified, and the bundling of the target paper is qualified.

[0096] In some embodiments provided by the present application, as shown in Fig. 3, the paper cutting and packaging system provided by the present application comprises a boxing detection mechanism and a boxing mechanism, and the control method for a paper cutting and packaging system further comprises: controlling the boxing detection mechanism to identify the paper information of the first sheet of paper of any second paper group in a plurality of second paper groups to obtain sixth paper information; verifying the sixth paper information against the second expected paper information; controlling the boxing detection mechanism to generate boxing information based on the matching of the sixth paper information and the second expected paper information; and controlling the boxing mechanism to load a plurality of second paper groups into a target box, and attaching a boxing label to the target box; wherein, the boxing label comprises the boxing information.

[0097] In the embodiment, the boxing detection mechanism is located in a front-end process of the boxing mechanism and consists of an image acquisition system, a backend industrial computer, and a human-machine interaction touchscreen. The boxing detection mechanism is configured to identify and verify the paper information of the target paper before boxing, record boxing data, etc. Through the PLC control, the boxing detection mechanism interacts with the boxing mechanism and the robotic arm, and executes a paper information acquisition triggering signal and label printing, and prompts the completion of printing and labeling, resending if a labeler image is not received, the completion of labeling image distribution, etc. Upon receiving a product in-place signal of the second paper group, the boxing detection mechanism can output a signal of normal paper information verification, a signal of abnormal verification, etc.

[0098] The boxing detection mechanism acquires images of the second paper groups, identifies the paper information of the first sheet of paper of any second paper group in a plurality of second paper groups, and obtains the sixth paper information, and the sixth paper information refers to the number of the topmost sheet of paper in the second paper group within the boxing mechanism.

[0099] The sixth paper information is verified against the second expected paper information. In the case that the sixth paper information matches the second expected paper information, i.e., the verification is qualified, the boxing detection mechanism generates the boxing information. Exemplarily, the boxing information can be numbers of all the banknotes or vouchers of the second paper groups in the box. By verifying the sixth paper information, the boxing detection mechanism determines whether the second paper group in the boxing mechanism matches the expected information, and ensures the correctness of the second paper group to be boxed.

[0100] The boxing detection mechanism uses a flipping device of the boxing mechanism to obtain any sixth paper information, verifies the sixth paper information against the data of the band device, and ensures the completion of normal production of the second paper group at the band device. If it is an abnormal product, whether manual intervention has been completed is determined. In addition, whether the paper information is duplicated is determined. Only the second paper groups that meet the above conditions can be boxed, otherwise, the second paper groups will be pushed out.

[0101] The boxing mechanism loads a plurality of second paper groups into the target box and attaches a boxing label to the target box, wherein, the boxing label comprises the boxing information. The boxing information comprises relevant information of the target paper inside the target box, and the boxing information can be obtained by scanning the boxing label.

[0102] It should be noted that in the case that the boxing mechanism fails and does not complete boxing, or a traceability process is required after the entire box is completed, the boxing mechanism needs to perform re-boxing through a batch number list and a box number control member, and transfer record table data of the box number in the database to a new table to realize data update.

[0103] Thus, the boxing detection mechanism verifies the sixth paper information and ensures the correctness of the second paper group to be boxed.

[0104] In some embodiments provided by the present application, as shown in Fig. 3, the paper cutting and packaging system provided by the present application comprises a box label detection mechanism, and the control method for a paper cutting and packaging system further comprises: controlling the boxing detection mechanism to send the boxing information to the box label detection mechanism; controlling the box label detection mechanism to acquire the label image of the boxing label, and comparing the label image with a third preset image to obtain a fourth verification result; controlling the box label detection mechanism to scan the boxing label to obtain the boxing label information; verifying the boxing label information against the boxing information and acquiring a fifth verification result; and outputting the fourth verification result and the fifth verification result.

[0105] In the embodiment, the box label detection mechanism is arranged at a box pressing cover of the boxing mechanism and consists of an image acquisition system, a backend industrial computer, and a human-machine interaction touchscreen. The box label detection mechanism uses a large data sample set for network training through a deep learning network, performs product sequence verification of the boxing mechanism, counts products in the box, determines the presence or absence of an inner box label and the quantity of the inner box label, performs identification and verification of the boxing label, as well as quality detection of the boxing label, and triggers two cameras (left and right cameras) to acquire images and outputs a signal of normal verification and a signal of abnormal verification, etc. upon receiving a paper in-place signal.

[0106] The boxing detection mechanism sends the boxing information to the box label detection mechanism. The box label detection mechanism acquires the label image of the boxing label and the position of the QR code in the box label image, and determines whether the QR code is skewed based on the bounding rectangle and rotation angle of the QR code. The box number is extracted through OCR recognition, the text and numbers in the QR code information are obtained, and high-low value detection on the text and numbers is performed. The label image is compared with the third preset image, and the defect point information in the image is acquired for blob (Binary Large Object) analysis to obtain the fourth verification result. The third preset image can be a boxing label image template pre-stored in the database. Based on the fourth verification result, whether the image of the boxing label is clear and qualified is determined.

[0107] The box label detection mechanism scans the boxing label and obtains the boxing label information. Exemplarily, the boxing label information is the banknote numbers or voucher numbers identified from the boxing label. The boxing label information and the boxing information are verified to obtain the fifth verification result. Based on the matching of the boxing label information and the boxing information, i.e., the verification is qualified, the boxing label information is accurate. The fourth verification result and the fifth verification result are output.

[0108] The box label detection mechanism obtains the box number of the current paper through the boxing database information of the boxing mechanism, adds it to a box number detection queue, acquires the first item in a box number comparison queue through a QR code detection point, and performs a box counting process. Qualified finished products after boxing are automatically transferred to a warehouse via AGC (Automatic Gain Control).

[0109] By establishing a high-speed computing center, remote and networked computing support is provided for each detection station. Detection workstations transmit images to the computing center for computation, and the results are fed back. The computing center adopts multi-site backup to prevent downtime of all detection workstations due to fault occurrence of a computing station. The computing center uses deep learning technology to provide a detection module with paper information recognition, band barcode number recognition, boxing label number recognition, bundling strip detection, and box detection. After the application of deep learning, the accuracy of each detection item is significantly higher than that of the original traditional algorithms.

[0110] Thus, the box label detection mechanism verifies the label image of the boxing label and ensures that the image of the boxing label is clear and qualified. The box label detection mechanism also verifies the boxing label information against the boxing information, and the boxing label information is accurate.
