Description

Technical Field

[0001] The present invention relates to the technical field of office equipment, and in particular to an integrated intelligent document processing device and a processing method. Background Art

[0002] In their daily work, government agencies, public institutions, large and medium-sized enterprises and other institutions generate a large number of paper documents that need to be archived. In response to archiving requirements, relevant national units have issued a series of policies and standards. According to relevant requirements, paper documents need to be printed and coded (referred to as coding, the same below) before archiving, that is, the side of the paper document containing characters needs to be coded; otherwise, no coding is done. After the coding is completed, the coded documents are scanned page by page in sequence to generate corresponding electronic files, which can not only achieve a one-to-one correspondence between paper documents and electronic files, but also improve the efficiency of file search. However, these tasks are currently highly dependent on manual labor, and there are problems such as low operating efficiency, uneven operating quality, and high costs.

[0003] In order to solve the above technical problems, the patent document with publication number CN111267498A discloses an intelligent paging coding machine and coding method, whose structure includes a machine body workbench, on which a paper feed mechanism, a paper detection mechanism, an induction coding mechanism and a paper pressing wheel are arranged in sequence according to the movement order of the paper. The method is to place the paper to be paged and coded between the two baffles of the machine body workbench, page it one by one through the paper feed wheel and the reverse wheel, the paper detection mechanism automatically identifies the content of the paper, the feedback system judges, and the coding is performed through the induction coding mechanism, and finally the coding is completed by unified collection. The coding machine integrates the paging and coding of paper document materials into an integrated process, and simultaneously improves the efficiency and accuracy of paper paging and coding. However, in actual applications, the coding machine still has the following technical problems:

[0004] 1. The coding machine only recognizes whether there are words on the back of the paper. Specifically, if the back is blank, only the front of the paper will be coded. If there are words on the back, both the front and back of the paper need to be coded. In the actual file management process, the paper is often placed upside down. Therefore, when the paper is placed upside down, the blank back of the paper will be coded, which will cause errors in the conversion of paper documents.

[0005] 2. The coding machine only codes paper documents, but does not encode the converted electronic files. The paper documents and electronic files cannot correspond one to one, which is not conducive to later management.

[0006] 3. The coding machine only realizes the paper conveyance through the cooperation of the pulley and the paper feed wheel, and the structure is relatively simple. On the one hand, the paper is easy to deviate during conveyance, and on the other hand, it is not conducive to the fast and stable conveyance of the paper, which ultimately leads to poor actual use effect.

[0007] 4. The coding machine realizes the feeding of paper documents to be processed through the cooperation of the paper feed wheel, the belt pulley and the reverse push wheel. However, due to the thickness of the gap between the paper feed wheel and the belt pulley, the number of papers that can be placed at a time is small. If there are many paper documents to be processed, it will need to be placed multiple times to complete the processing of the documents. Therefore, there is a technical problem of small paper feed amount and affecting processing efficiency. Summary of the invention

[0008] The purpose of the present invention is to overcome the above-mentioned technical problems existing in the prior art, and to provide an integrated intelligent document processing device and a processing method.

[0037] The coding method comprises the following steps:

[0038] Step 1: Put the paper to be processed into the paper feeding device, and the paper feeding device feeds the paper into pages to the paper conveying device, and the paper conveying device controls the paper to move toward the storage device;

[0039] Step 2: When the paper moves to below the upper image acquisition device, the upper image acquisition device acquires an image of the upper surface of the paper; when the paper moves to the image acquisition gap, the lower image acquisition device acquires an image of the lower surface of the paper through the image acquisition gap; after acquisition is completed, the acquired image is sent to the controller;

[0043] The advantages of adopting the present invention are:

[0044] 1. The present invention uses a reasonable layout to uniformly install the controller, paper feeding device, paper conveying device, storage device, image acquisition device and coding device on the base to form an integrated intelligent document processing device, wherein the image acquisition gap facilitates the image acquisition device below to collect images of the lower surface of the paper, so that the upper and lower image acquisition devices can basically collect images on both sides at the same time, which can shorten the acquisition time and thus improve the acquisition efficiency, and on the other hand, it is conducive to shortening the length of the paper conveying device, thereby reducing the volume and space occupation of the device. By scanning and identifying the upper and lower sides of a sheet of paper, it can prevent the paper from being placed upside down, which is conducive to improving the processing effect of the paper. By identifying the image containing characters and arranging the page number value of the image containing characters in sequence, on the one hand, it can code the corresponding paper page, and on the other hand, it can realize the intelligent paging of the converted electronic file, which is conducive to improving the processing effect of the paper file. In addition, in actual use, even if the paper is placed upside down, the page with characters on the paper can be accurately converted into an electronic part, and the corresponding paper can be coded, which is conducive to preventing data loss.

[0046] 2. The present invention designs the paper feeding device, paper conveying device and storage device to be an integrated structure using the same frame, making the structure of the device more streamlined and more integrated, thereby effectively simplifying the structure of the device and reducing the size of the device. Compared with the prior art with publication number CN111267498A, the present invention is equivalent to providing another coding device with a completely different structure, but better conveying effect, better electronic conversion effect and higher processing efficiency, and thus has a higher degree of innovation.

[0047] 3. The present invention uses a linear array camera for image acquisition, which can accurately acquire images without stopping the paper and obtain image files of better quality. The image files have the clarity of scanned copies after being converted into electronic files, thus making the quality of the converted electronic files better. At the same time, the use of a linear array camera can also reduce the width of the image acquisition gap, that is, it can accurately acquire paper images under the premise of a narrow image acquisition gap, which is conducive to further reducing the size of the device. In addition, the lighting lamp can provide light for the linear array camera when acquiring images, thereby obtaining electronic images with higher clarity.

[0048] 4. The present invention adopts two anti-deviation conveying sections with anti-deviation function as paper conveying devices to convey paper. It can effectively prevent the paper from deviating during the conveying process and make the paper move in a straight line in the horizontal direction, which is conducive to realizing fast and stable conveying of paper, and improves the accuracy of paper conveying, and has better practicality.

[0049] 5. The present invention cooperates with a conveying component, a power mechanism and an anti-deviation mechanism of a specific structure, which can effectively prevent the paper from deflecting during the paper conveying process, so that the paper can move in a straight line in the horizontal direction, which not only ensures that all papers move in a consistent manner, but also meets the requirements of the image acquisition device for collecting images, thereby achieving the technical effect of improving the accuracy of paper conveying and improving the quality of electronic file conversion.

[0050] In addition, the anti-deviation conveying section of this specific structure is also suitable for the continuous and stable conveyance of smaller bill paper, medium-sized A4 paper and larger A3 paper, which is conducive to meeting the needs of different scenarios.

[0051] 6. The present invention uses a transition roller group, which is beneficial to the stable transportation of paper and the accurate coding of the coding device.

[0052] 7. The present invention sets the rotation speed of the power mechanism in the two anti-deviation conveying sections to 0-3000r / min. On the one hand, the corresponding rotation speed can be selected according to the needs to meet the requirements of different working conditions. On the other hand, it is conducive to improving the processing efficiency of paper documents.

[0053] 8. The present invention can stably support the paper during transportation and constrain the paper to move in a predetermined direction through the cooperation of a paper support plate, a pressure guide plate and a plurality of conveying rollers of a specific structure, which is conducive to the stable transportation of the paper and has the advantages of simple structure and convenient operation. In addition, the pressure guide plate can also constrain the paper from the other side during the paper transportation process to prevent the paper from failing to be transported due to the phenomenon of warping, etc., thereby helping to improve the success rate of paper transportation.

[0054] In addition, each anti-deviation conveying section in the present invention can drive all conveying rollers by using a set of power mechanisms, and has the advantages of simple structure, low cost, stable driving, good conveying effect and not easy to damage paper.

[0055] 9. The present invention sets the upper surface of the paper support board and the upper surface of the rubber-coated wheel to be in the same plane. On the one hand, it can ensure better power to drive the paper, and on the other hand, it can prevent the paper from being damaged due to inconsistent heights, which is conducive to improving better transportation effects.

[0056] 10. The present invention uses a deflection correction frame with a specific structure and multiple universal deflection correction parts as an anti-deflection mechanism, wherein the side deflection correction plate can adjust the deflection of the paper from the side of the paper during paper transportation, and the universal deflection correction part can adjust the deflection of the paper from the top of the paper during paper transportation, and can also provide a certain friction force for paper transportation. The combination of the two can effectively ensure the horizontal and straight line transportation of the paper while preventing the paper from deflecting, which will not cause damage to the paper and has the advantage of better transportation effect.

[0057] 11. The present invention adopts a deviation-correcting frame with a specific structure, which can reasonably integrate the various components in the anti-deviation mechanism into one, and has the advantages of simple structure, easy installation and good anti-deviation effect.

[0058] 12. The present invention can guide the paper as it enters by means of the outwardly inclined side guide plates and the downwardly inclined bottom guide plates, so that the paper can accurately enter the conveying assembly for conveyance.

[0059] 13. The present invention provides an adaptive angle adjustment mechanism in the paper feeding device that can control the adaptive rotation of the tray. In actual use, the single amount of paper documents put in can be adjusted by adjusting the rotation angle of the tray. For example, the amount of paper put in the tray can be increased by controlling the paper outlet end of the tray to rotate downward from a horizontal state, thereby effectively improving the paper feeding efficiency. In addition, the adaptive angle adjustment mechanism has an adaptive adjustment function. During the document processing process, as the upper paper is sent away, the position of the paper located at the lower part and the bottom of the tray can be adaptively raised, thereby achieving a more accurate and stable paper feeding effect. In summary, the present invention has the technical effects of large paper feeding amount, high paper feeding efficiency and good paper feeding effect through a structural member with an adaptive adjustment function.

[0060] 14. The adaptive angle adjustment mechanism of the present invention is mainly composed of an adjustment member, a pin shaft, a limit column, a linkage pin, a linkage block, an upper tension member, a side tension member and a spring. On the one hand, it has the advantages of a relatively simple structure and easy control. On the other hand, through two springs respectively connected to the upper tension member and the side tension member, it can also provide adaptive force for the tray from two directions, which is conducive to improving the stability of the adaptive force.

[0061] 15. The present invention provides a plurality of hanging holes on both the upper tension member and the side tension member, so that the spring can be hung in different hanging holes, which is helpful for adjusting the best adaptive force for the device according to actual needs.

[0062] 16. The present invention adopts a semicircular groove as an arc-shaped limit groove and is arranged around the pin shaft, which has the advantages of a longer adjustment stroke of the adjustment member, a larger rotation angle of the tray, an increased single paper loading amount and stable adjustment.

[0063] 17. The present invention adopts a paper picking mechanism with a specific structure, which has the advantages of stable paper picking and good effect. The oblique stop on the support platform can prevent the paper on the tray from falling from the gap between the paper outlet end and the support platform, which is conducive to ensuring the accuracy and stability of paper feeding.

[0064] 18. The present invention can control the rotation of the paper separation platform through the paper feeding force adjustment mechanism, thereby realizing the adjustment of the gap between the paper separation platform and the paper pickup wheel. By adjusting the gap between the paper separation platform and the paper pickup wheel, the best paper pickup force can be provided for the paper to be fed, which is conducive to achieving a better and more stable paper feeding effect. In addition, the paper feeding force adjustment mechanism adopting this structure also has the advantages of being relatively simple in structure and easy to adjust.

[0065] 19. The present invention makes the control of the paper feeding force adjustment mechanism simpler and more convenient by using the rotating disk, and by setting a numerical value indicating the rotation angle on the rotating disk, it is conducive to the accurate adjustment of the paper feeding gap, thereby ensuring a better paper feeding effect.

[0066] 20. The present invention provides a guiding slope on the paper separation platform, which is conducive to allowing the paper to continuously and stably enter between the paper separation platform and the paper pickup wheel.

[0067] 21. The present invention adopts a pallet with a folding structure, which can reduce the space occupied by the equipment when not in use and is more conducive to the carrying and transportation of products.

[0068] 22. The present invention can realize the automatic opening and closing of each device and timely detect faults through the cooperation of the paper jam detection component, the paper overlap detection component and various sensors, thereby effectively reducing the working time of each device and improving the accuracy of paper document processing.

DETAILED DESCRIPTION

[0085] Example 1

[0086] like Figure 1 As shown, the integrated intelligent document processing device includes a base 1, on which a controller (not shown), a paper feeding device 4, a paper conveying device 5, a storage device 8, an image acquisition device 6 and a coding device 7 are fixed respectively. The paper feeding device 4, the paper conveying device 5, the coding device 7 and the storage device 8 are arranged in sequence, and an image acquisition gap 9 is provided in the middle of the paper conveying device 5. The image acquisition devices 6 are respectively arranged above and below the image acquisition gap 9, and the upper image acquisition device 6 is located at the front side of the image acquisition gap 9, and the lower image acquisition device 6 is located directly below the image acquisition gap 9. The coding device 7 is respectively arranged above and below the output end of the paper conveying device 5. The controller can be fixed at the lower part of the base 1, and is respectively connected to the paper feeding device 4, the paper conveying device 5, the image acquisition device 6 and the coding device 7. Among them,

[0087] The paper feeding device 4 is used to feed the to-be-processed paper to the paper feeding device 5 in pages; the paper feeding device 5 is used to feed the to-be-processed paper to the storage device 8 in sequence; the image acquisition device 6 is used to respectively acquire images of the upper and lower surfaces of the paper during the paper feeding process; the controller is used to identify images containing characters; to arrange the page number values ​​of the images containing characters in sequence; to send the page number values ​​to the coding device 7 for coding the corresponding pages of the corresponding paper; and to electronically encode and save the corresponding images after coding is completed; the storage device 8 is used to collect the paper after coding is completed.

[0088] It should be noted that the coding device 7 is used to code the page containing characters according to the page number value sent by the controller. For example, if the controller recognizes that the upper surface page of the paper to be processed contains characters, it arranges the corresponding page number value for the page number, and then sends the page number value to the upper coding device 7, and codes the upper surface of the paper when it moves to the bottom of the upper coding device 7, so as to achieve a one-to-one correspondence between the paper document and the converted electronic file.

[0089] In this embodiment, an image acquisition gap 9 is provided in the middle of the paper conveying device 5 to facilitate the image acquisition device 6 below. This setting is the preferred method of this embodiment, but in fact, a transparent glass plate / acrylic plate can also be provided in the middle of the paper conveying device 5 to play a role equivalent to the image acquisition gap 9.

[0090] This embodiment does not limit the specific structures of the base 1, the paper feeding device 4, the paper conveying device 5, the storage device 8, the image acquisition device 6 and the coding device 7, which can be implemented by using existing conventional structures. For example, the coding device 7 can be a coding machine, and the storage device 8 can be a foldable bracket. As long as these conventional structures can be arranged according to the above structure to perform intelligent paging and coding of paper documents, and finally make the paper documents correspond to the page numbers of the electronic archives one by one.

[0091] It should be noted that the image acquisition device 6 in this embodiment can use an ordinary area array camera or a line array camera 16 to acquire images, but the specific device used to acquire images is also related to the length and width of the image acquisition gap 9. For example, when an ordinary area array camera is used to acquire images, the length and width of the image acquisition gap 9 can be set to be slightly smaller than the length and width of the paper, so that the paper is supported by the four sides of the paper. In this way, when the paper runs to the position of the image acquisition gap 9, the pages containing the character part on the lower surface of the paper are exposed in the area array camera window below, and the image of the lower surface of the paper can be acquired by the area array camera. Furthermore, in order to provide stability for the paper when passing through the image acquisition gap 9, a transparent glass plate / acrylic plate can be fixed in the image acquisition gap 9 to support the paper, and when the paper runs to the transparent glass plate / acrylic plate, the image can be acquired by the area array camera below.

[0092] However, although the above-mentioned ordinary area array camera can also capture images, its image capture effect is general, and it is also necessary to ensure that the length and width of the image capture gap 9 are larger, which will cause the overall size of the device to become larger, which is not conducive to the refinement and miniaturization of the device. For this reason, this embodiment preferably uses a linear array camera 16 for image capture. On the one hand, this makes it possible to use a smaller image capture gap 9 to achieve effective image capture. On the other hand, it can also obtain images with better capture effects and higher quality without stopping the paper.

[0093] Furthermore, the image acquisition device 6 in this embodiment also includes an illumination lamp 17. The line array camera 16 and the illumination lamp 17 are both fixed to the base 1 through a bracket. The illumination lamp 17 can provide illumination when the line array camera 16 acquires images. During the paper conveying process, the illumination lamp 17 can illuminate the upper and lower surfaces of the paper respectively, so that a clearer image can be acquired, which is beneficial to improving the quality of the electronic file.

[0094] The controller in this embodiment has the above-mentioned processing function and storage function, etc., which can be implemented in any appropriate manner. For example, the controller can take the form of a microprocessor or processor and a computer-readable medium storing a computer-readable program code (such as software or firmware) that can be executed by the (micro) processor, a logic gate, a switch, an application-specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller. Those skilled in the art also know that in addition to implementing the controller in a pure computer-readable program code manner, the controller can be made to implement the same function in the form of a logic gate, a switch, an application-specific integrated circuit, a programmable logic controller, and an embedded microcontroller by logically programming the method steps. Therefore, this controller can be considered as a hardware component, and the device for implementing various functions included therein can also be regarded as a structure within the hardware component. Or even, the device for implementing various functions can be regarded as both a software module for implementing the method and a structure within the hardware component.

[0095] In actual application, a shell can be set on the outside of the entire device to ensure better overall aesthetics of the product. In addition, to facilitate the operation and control of the device, a human-machine interaction unit connected to the controller can be set on the upper part of the device to facilitate the operation and control of the device through the human-machine interaction unit.

[0096] Example 2

[0097] Based on Example 1, this example further simplifies the structure and size of the device. Figure 1-6 As shown, in this embodiment, the paper feeding device 4, the paper conveying device 5 and the storage device 8 are designed to be an integrated structure fixed to the same frame 2, that is, the paper feeding device 4, the paper conveying device 5 and the storage device 8 are all fixed on the same frame 2.

[0098] Specifically, the frame 2 includes two side panels, which can be fixed to each other through a crossbeam, the paper feed device 4 and the storage device 8 are respectively installed at both ends through the side panels, and the paper conveying device 5 is installed between the paper feed device 4 and the storage device 8 through the side panels. Correspondingly, the image acquisition device 6 can be respectively fixed above and below the image acquisition gap 9 through the frame 2, and the coding device 7 can be respectively fixed above and below the output end of the paper conveying device 5 through the frame 2. Since the same frame 2 structure is adopted, the paper feed device 4, the paper conveying device 5 and the storage device 8 can form an integrated structure, thereby making the structure of the device more streamlined, the volume more compact, and the processing of paper documents smoother.

[0099] Example 3

[0100] Based on the second embodiment, this embodiment further defines the structure of the paper conveying device 5. Figure 1-6 As shown, the paper conveying device 5 includes two front and rear anti-deviation conveying sections 18 transversely mounted on the frame 2, and the image acquisition gap 9 is located between the anti-deviation conveying sections 18. In this embodiment, the anti-deviation conveying section 18 can prevent the paper from deviating during conveying, and can keep the paper in horizontal linear motion, thereby ensuring a continuous and stable conveying effect of the paper.

[0101] The anti-deviation conveying section 18 includes a conveying assembly 19, a power mechanism 20 and an anti-deviation mechanism 21, all of which are mounted on the frame 2.

[0102] The conveying assembly 19 is installed between two side plates of the frame 2 and is used for conveying paper.

[0103] The power mechanism 20 can be specifically fixed on one of the side panels to drive the conveying assembly 19 to convey the paper. Optionally, the power mechanism 20 includes a set of conveying motors and connecting parts, the connecting parts can be belts, chains, gear racks, etc., the conveying motor is fixed on the side panel, and the conveying motor can drive the conveying assembly 19 to move through the connecting parts.

[0104] In addition, in order to ensure the consistency of paper conveying and prevent paper from being damaged during conveying, the speeds of the motors in the two anti-deviation conveying sections 18 in this embodiment are set to be the same. Further, the speeds of the conveying motors in the two anti-deviation conveying sections 18 are both 0-3000r / min, and the appropriate speed can be selected according to the needs.

[0105] The anti-deviation mechanism 21 can be specifically fixed on another side plate, and is used to prevent the paper from deflecting when conveying the paper, and makes the paper move in a horizontal straight line. Of course, according to actual needs, the anti-deviation mechanism 21 and the power mechanism 20 can also be fixed on the same side plate.

[0106] Furthermore, in order to achieve stable paper conveying and accurate coding of the coding device 7, the anti-deviation conveying section 18 further includes a transition roller group 3 driven by a power mechanism 20, the transition roller group 3 of the previous anti-deviation conveying section 18 is arranged between the anti-deviation conveying section 18 and the paper feeding device 4, and the transition roller group 3 of the next anti-deviation conveying section 18 is arranged between the anti-deviation conveying section 18 and the storage device 8. Preferably, the transition roller group 3 in each anti-deviation conveying section 18 is driven by the power mechanism 20 in the anti-deviation conveying section 18, which can simplify the structure and save costs on the one hand, and make the rotation speed of the front and rear anti-deviation conveying sections 18 consistent on the other hand, so as to ensure stable paper conveying.

[0107] It should be noted that the transition roller set 3 in this embodiment can be formed by four or more rubber rollers combined in pairs, and the coding device 7 can be arranged between the latter transition roller sets 3 .

[0108] like Figure 7-9 As shown, the conveying assembly 19 includes a plurality of conveying rollers 22. The number of conveying rollers 22 can be determined according to actual needs. For example, 4-10 conveying rollers 22 can be used to convey A4 paper. Each conveying roller 22 is evenly mounted on the side plate through bearings. Each conveying roller 22 can form a linkage structure by using a belt to be connected to each other. Then, the conveying motor is connected to one of the conveying rollers 22 through a belt, and the conveying motor can uniformly drive all the conveying rollers 22 to rotate. In addition, the end of one end of each conveying roller 22 is fixedly sleeved with a rubber-coated wheel 24 for driving the paper. The outer diameter of the rubber-coated wheel 24 is larger than the outer diameter of the conveying roller 22. During actual conveying, the rubber-coated wheel 24 is mainly used to drive the paper.

[0109] It should be noted that the rubber-coated wheel 24 is fixed to the end of the conveying roller 22, which means that the rubber-coated wheel 24 is fixed to one end of the conveying roller 22 located between the side plates, that is, the rubber-coated wheel 24 is located between the side plates and close to one of the side plates.

[0110] like Figure 3 , 7 As shown in Figure 8, the conveying assembly 19 also includes a paper support 23, which is a flat plate, and its length is substantially the same as the overall length of the conveying assembly 19. The paper support 23 is horizontally covered above the plurality of conveying rollers 22 through the side plates, and is located between the rubber-coated wheel 24 and the side plates. There is a certain gap between the paper support 23 and the conveying roller 22, which will not affect the rotation of the conveying roller 22. In addition, in order to avoid damage to the paper and ensure the stable conveying of the paper, after the paper support 23 is installed above the conveying roller 22, its upper surface and the upper surface of the rubber-coated wheel 24 when it is stationary are in the same plane, that is, the heights of the two are the same. During actual conveying, after the paper enters the conveying assembly 19 from the input end, one side of the paper is located above the rubber-coated wheel 24, and the rest of the paper is located on the paper support 23. Since the paper is driven only by the rubber-coated wheel 24 on one side at this time, it will inevitably deviate. Therefore, the continuous and stable conveying of the paper can be achieved through the control of the anti-deviation mechanism 21.

[0111] Furthermore, in order to prevent the paper from not being able to accurately enter the conveying assembly 19, the present embodiment tilts the paper feed end of the paper support paper 23 downward to form a bottom guide plate 34. The bottom guide plate 34 can guide the paper from the end of the paper when the paper enters. Even if the front end of the paper is slightly lower than the upper surface of the paper support paper 23, the paper can smoothly enter the conveying assembly 19 under the guidance of the bottom guide plate 34, thereby making the paper conveying more accurate.

[0112] like Figure 3-4 As shown, the conveying assembly 19 further includes a pressure guide plate 35, which is a strip plate fixed above the paper support 23 through the frame 2 and located on the other side away from the rubber-coated wheel 24. There is a certain gap between the pressure guide plate 35 and the paper support 23, and its function is to exert a certain pressure on the other side of the paper when the paper passes through, so as to ensure a more stable conveying effect of the paper. In addition, the pressure guide plate 35 is arranged on the other side away from the rubber-coated wheel 24, which can also provide space for the subsequent installation of the detection assembly.

[0113] like Figure 7-9 As shown, the anti-deviation mechanism 21 includes a deflection correction frame 25, which is fixed on the frame 2, and its length is substantially consistent with the overall length of the conveying assembly 19. The deflection correction frame 25 includes a vertically arranged side deflection correction plate 29 and a horizontal plate 30 perpendicular to the side deflection correction plate 29, and the side deflection correction plate 29 is located at the end of the rubber-coated wheel 24, and the lower end of the side deflection correction plate 29 is located below the upper surface of the rubber-coated wheel 24. During the paper conveying process, the paper is perpendicular to the side deflection correction plate 29 and is just blocked by the side deflection correction plate 29, so the side deflection correction plate 29 can be used to correct the paper from the side of the paper to prevent deviation.

[0114] like Figure 7-9 As shown, the correcting frame 25 also includes an adapter plate 31 perpendicular to the side correcting plate 29 and a side connecting plate 32 parallel to the side correcting plate 29. The side connecting plate 32, the adapter plate 31 and the side correcting plate 29 are connected together to form a U-shaped structure. The correcting frame 25 is fixed to the frame 2 through the side connecting plate 32.

[0115] Furthermore, in order to prevent the paper from not being able to accurately enter the conveying assembly 19, the present embodiment tilts the paper feed end of the side deflection correction plate 29 outward to form a side guide plate 33. The side guide plate 33 can guide the paper from the end side when the paper enters. Even if the end side of the paper slightly exceeds the limited range of the side deflection correction plate 29, the paper can smoothly enter the conveying assembly 19 under the guidance of the side guide plate 33, thereby making the paper conveying more accurate.

[0116] The anti-deviation mechanism 21 also includes a plurality of universal deflection correcting members 26, the number of which is the same as the number of the conveying rollers 22. A plurality of through holes are provided on the transverse plate 30, and each universal deflection correcting member 26 is fixed directly above each rubber-coated wheel 24 through the through holes on the transverse plate 30, and a paper passing gap is formed between each universal deflection correcting member 26 and each rubber-coated wheel 24. When conveying paper, the universal deflection correcting member 26 cooperates with the side deflection correcting plate 29 to prevent the paper from deflecting.

[0117] Specifically, the universal deflection correcting member 26 includes a cylinder 27 and a universal ball 28. The cylinder 27 is fixed on the horizontal plate 30. The universal ball 28 is movably arranged at the lower end of the cylinder 27. Each universal ball 28 is tangent to each rubber-coated wheel 24, and the paper passes through the gap between the universal ball 28 and the rubber-coated wheel 24. During actual transportation, the universal deflection correcting member 26 can correct the paper from above the paper through the universal ball 28 during the paper transportation process, and can also provide a certain friction force for the transportation of the paper. This structure combined with the side deflection correcting plate 29 can effectively ensure the horizontal and straight transportation of the paper while preventing the paper from deflecting.

[0118] It should be noted that the paper conveying device 5 including the anti-deviation conveying section 18 in this embodiment is suitable for the continuous and stable conveying of smaller bill paper, medium-sized A4 paper and larger A3 paper, and is particularly suitable for the conveying of A4 paper. In actual application, the paper is first fed into the input end of the conveying assembly 19, and then the conveying assembly 19 is driven by the power mechanism 20, and the conveying assembly 19 can drive the paper to move toward the output end. During the paper movement process, the anti-deviation mechanism 21 cooperates with the conveying assembly 19, which can prevent the paper from deviating and make the paper move in a straight line in the horizontal direction, thereby achieving the purpose of stable paper conveying.

[0119] The working principle of this embodiment is:

[0120] The conveying motor is started, and all the conveying rollers 22 are driven by the conveying motor to rotate. When the paper to be conveyed enters the paper support board 23 and the corresponding paper passing gap from the input end of the conveying assembly 19, the paper moves to the output end under the driving of the rubber-coated wheel 24 and the universal ball 28. During the conveying process, the side edge of the paper is just blocked by the side correction plate 29, and the side correction plate 29 can correct the paper from the side edge of the paper, which not only prevents the paper from running off, but also ensures the horizontal and straight conveying of the paper, so that the paper has a stable conveying effect.

[0121] When the paper moves to below the upper image acquisition device 6 , the upper image acquisition device 6 starts to scan the image, and when the paper is conveyed to the image acquisition gap 9 , the lower image acquisition device 6 starts to scan the image.

[0122] Then, the controller identifies the image containing characters and deletes the blank image based on the image captured by the image acquisition device 6, and intelligently assigns page numbers to the pages containing characters according to the sequence, and sends the page numbers to the coding device 7 to code the corresponding side of the corresponding paper, and after the coding is completed, the corresponding image is electronically encoded and saved. Since the device can not only ensure the stable transportation of paper, but also intelligently identify the image containing characters and intelligently paginate accordingly, the processing efficiency and processing effect of paper documents are further improved, and electronic files with better quality can be obtained more quickly.

[0123] Example 4

[0124] Based on any one of Embodiments 1-3, this embodiment further limits the structure of the paper feeding device 4.

[0125] like Figure 6 , 10 As shown in FIG. 12 , the paper feeding device 4 includes a tray 36, a paper picking mechanism 37 and an adaptive angle adjustment mechanism 38.

[0126] The tray 36 is rotatably mounted on the frame 2 via a rotating shaft 39 , and the tray 36 is used for placing paper documents to be processed.

[0127] The paper pickup mechanism 37 is installed at the paper output end of the tray 36 through the frame 2 . The paper pickup mechanism 37 is used to apply force to the topmost paper on the tray 36 so as to page the paper on the tray 36 and feed it into the paper conveying device 5 .

[0128] The adaptive angle adjustment mechanism 38 is installed on one side of the frame 2. The adaptive angle adjustment mechanism 38 can control the tray 36 to adaptively rotate within a certain angle range through the rotating shaft 39.

[0129] In actual use, the paper output end of the tray 36 can be controlled by the adaptive angle adjustment mechanism 38 to rotate downward from a horizontal state to increase the paper output capacity of the tray 36. After the paper documents to be processed are placed, the adaptive angle adjustment mechanism 38 will control the tray 36 to reset through adaptive force until the top paper contacts the paper picking mechanism 37. The paper picking mechanism 37 then applies force to the paper to feed the pages of paper into the paper conveying device 5, thereby achieving the technical effect of large single-time paper output, more accurate paper feeding, and more stable paper feeding.

[0130] It should be noted that the adaptive angle adjustment mechanism 38 can control the tray 36 to adaptively rotate within a certain angle range through the rotating shaft 39, which means that after placing paper on the tray 36, the adaptive angle adjustment mechanism 38 generates a continuous adaptive rotational force on the tray 36, so that the top paper on the tray 36 maintains a continuous contact force with the paper picking mechanism 37, thereby achieving a better paper feeding effect.

[0131] Specifically, Figure 3-6 As shown, the paper pickup mechanism 37 includes a paper pickup motor 48, a support 49, a paper pickup roller 50 and a paper pickup wheel 51.

[0132] The support platform 49 is fixed to the paper discharge end of the tray 36. The support platform 49 is provided with a smooth plane inclined at a certain angle toward the paper discharge end, through which the smooth plane can cooperate with the tray 36 and the pickup roller 51 to achieve smooth paper feeding. In addition, the support platform 49 is also provided with an oblique stopper 52 corresponding to the paper discharge end, the oblique stopper 52 is located at the lower end of the smooth plane of the support platform 49, and the lower end of the oblique stopper 52 is located below the tray 36 when it rotates to the lowest point, so as to prevent the paper on the tray 36 from falling from the gap between the paper discharge end and the support platform 49, thereby improving the accuracy and stability of paper feeding.

[0133] The pickup wheel 51 is fixed to the middle of the pickup roller 50 , and the pickup wheel 51 is rotatably disposed above the support platform 49 through the pickup roller 50 .

[0134] The pickup motor 48 is fixed to one side of the frame 2 and connected to the pickup roller 50 . The pickup motor 48 and the pickup roller 50 control the rotation of the pickup wheel 51 , so that the paper on the tray 36 can be paged and sent to the paper conveying device 5 .

[0135] like Fig.11 As shown, the adaptive angle adjustment mechanism 38 includes an adjustment member 40, a pin 41, a limit column 42, a linkage pin 43, a linkage block 44, an upper tension member 45, a side tension member 46 and a spring (not shown in the figure).

[0136] The adjusting member 40 may be a plate-like structure, which includes a control end and a connecting end, and the connecting end is rotatably mounted on the frame 2 through a pin shaft 41. In addition, the connecting end is also provided with an arc-shaped limiting groove 47, which is a semicircular groove around the pin shaft 41. The arc-shaped limiting groove 47 is used to cooperate with the limiting column 42 to limit the rotation angle of the tray 36, and its specific length and position can be set accordingly according to actual needs.

[0137] The limiting column 42 is fixed on the frame 2 and is located in the arc-shaped limiting groove 47 . The limiting column 42 cooperates with the arc-shaped limiting groove 47 to limit the rotation angle of the tray 36 .

[0138] The upper tension member 45 and the side tension member 46 are respectively fixed above the rotating shaft 39 and on one side of the connecting end in the horizontal direction, and both the upper tension member 45 and the side tension member 46 are substantially L-shaped structural members for easy fixation.

[0139] The linkage block 44 is a long strip structure, the upper end of which is fixedly connected to the rotating shaft 39, and the lower end of which is provided with a linkage slot / hole and a hanging hole. The hanging hole is located below the linkage slot / hole, and the hanging hole is connected to the side tension member 46 through a spring.

[0140] One end of the linkage pin 43 is fixed on the connecting end, and the other end is located in the linkage / hole and matches with the linkage slot / hole. In addition, the end of the linkage pin 43 is also connected with the upper tension member 45 through a spring.

[0141] The control end of the adjusting member 40 is provided with a flat handle, through which the adjusting member 40 can be controlled to rotate, and then the tray 36 can be controlled to rotate through the linkage pin 43, the linkage block 44 and the rotating shaft 39, so as to facilitate the placement of paper documents to be processed. When the paper documents are placed in the tray 36, under the cooperation of the upper tension member 45, the side tension member 46 and the two springs, it can generate a continuous adaptive rotation force on the tray 36 (the rotation direction of the adaptive rotation force is opposite to the direction of the rotation of the tray 36 controlled by the handle), so that the top paper on the tray 36 maintains a continuous contact force with the paper pickup mechanism 37, thereby ensuring a better paper feeding effect.

[0142] In order to ensure that the adaptive angle adjustment mechanism 38 produces a better adaptive force on the tray 36, the present embodiment preferably provides a plurality of hanging holes on the upper tension member 45 and the side tension member 46. According to different needs, the two springs can be hung in different hanging holes respectively, so as to obtain a better adaptive force and a better paper feeding effect.

[0143] In order to reduce the space occupied by the device when not in use and to facilitate the carrying and transportation of the device, the present embodiment preferably sets the tray 36 to an existing conventional folding structure. The folding structure can be as follows: the tray 36 includes a rotating disk 60 and a folding disk, the rotating disk 60 is mounted on the frame 2 via a rotating shaft 39, and the folding disk is connected to the rotating disk 60 via a folding structure. When not in use, the folding disk can be folded onto the rotating disk 60.

[0144] The working principle of this embodiment is: Fig.11 Taking the direction shown as an example, first manually control the lower end of the linkage block 44 to move to the left through the adjustment member 40 and the linkage pin 43. At this time, the linkage block 44 controls the paper outlet end of the tray 36 to tilt downward through the rotating shaft 39, so that the distance between the paper outlet end and the pickup roller 51 is increased. When the distance reaches the maximum, a large amount of paper can be put in a single batch. After the paper is put in, release the adjustment member 40. At this time, the two springs drive the linkage block 44 to move to the right, and correspondingly drive the paper outlet end of the tray 36 to move upward through the rotating shaft 39 until the top paper on the tray 36 contacts the pickup roller 51. In this process, under the cooperation of the upper tension member 45, the side tension member 46 and the two springs, it can generate a continuous adaptive rotation force on the tray 36, so that the top paper on the tray 36 can maintain a continuous contact force with the pickup mechanism 37, thereby ensuring a better paper feeding effect.

[0145] Example 5

[0146] On the basis of Example 4, this embodiment further fixes a paper feeding force adjustment mechanism 53 on the frame 2. The paper feeding force adjustment mechanism 53 is connected to the frame 2 and the support platform 49 respectively, and can improve the paper feeding effect by adjusting the force between the paper pickup wheel 51 and the paper.

[0147] like Figure 13-15 As shown, the paper feeding force adjustment mechanism 53 includes an adjustment rod 54, an adapter 55, a positioning column 56, a wedge block 57, a paper separation platform 58 and a paper separation frame 59; the support platform 49 includes an inner cavity consistent with the length direction of the pickup roller 50, and a mounting hole communicating with the inner cavity is opened on the support platform 49, and the mounting hole is located directly below the pickup roller 51.

[0148] The wedge block 57 is slidably disposed in the inner cavity through a conventional limiting structure, and can slide along the length direction of the inner cavity.

[0149] One end of the adapter 55 is fixed on the wedge block 57, and the other end extends out of the inner cavity and then passes through the side plate of the frame 2. In addition, the adapter 55 is also provided with a limit bar hole.

[0150] The positioning column 56 is fixed in the limiting strip hole through the bottom of the inner cavity. The positioning column 56 cooperates with the limiting strip hole to limit the sliding distance of the wedge block 57.

[0151] The paper separation rack 59 is fixed in the inner cavity.

[0152] The outer diameter of the paper separation platform 58 is slightly smaller than the inner diameter of the mounting hole. The front end of the paper separation platform 58 is provided with a guide slope corresponding to the paper discharge end. The rear end of the paper separation platform 58 is movably sleeved on the paper separation frame 59. The paper separation platform 58 is rotatably arranged in the mounting hole through the paper separation frame 59. In addition, a universal ball is arranged at the lower part of the paper separation platform 58, and the paper separation platform 58 is arranged on the wedge surface of the wedge block 57 through the universal ball.

[0153] The adjusting rod 54 is vertically rotatably mounted on the frame 2, and the lower end of the adjusting rod 54 is fixedly connected to the adapter 55. The adjusting rod 54 can control the rotation of the front end of the paper separation platform 58 through the adapter 55 and the wedge block 57, and accordingly increase or decrease the gap between the paper separation platform 58 and the paper pickup wheel 51, so that the paper pickup wheel 51 can generate better paper pickup power for the paper.

[0154] It should be noted that the middle part of the adjustment rod 54 is rotatably connected to the frame 2 through an L-shaped structural member, but there is a certain rotation resistance between the adjustment rod 54 and the L-shaped structural member. Only when the rotation force applied to the adjustment rod 54 is greater than the resistance, the adjustment rod 54 will rotate, which ensures better operation stability of the paper feeding force adjustment mechanism 53. In addition, a semicircular rotating disk 60 is horizontally fixed to the upper end of the adjustment rod 54, and a numerical value indicating the rotation angle is provided on the rotating disk 60. According to the numerical value indicating the rotation angle, the gap between the pickup wheel 51 and the paper separation table 58 can be more accurately adjusted.

[0155] Furthermore, since the rotating disk 60 is arranged horizontally, it occupies more lateral space. Therefore, in order to make the distance between the rotating disk 60 and the side plate of the frame 2 smaller, this embodiment also provides a clearance hole on the side plate. When the rotating disk 60 is fixed on the adjustment rod 54, its edge portion can pass through the clearance hole and enter the inner side of the side plate.

[0156] The working principle of this embodiment is as follows: in the actual working process, when the paper picking force of the paper picking wheel 51 on the paper is insufficient, the adjusting rod 54 is first controlled to rotate a certain angle by the rotating disk 60, and then the adjusting rod 54 controls the wedge block 57 to move toward the adjusting rod 54 through the adapter 55, and the wedge block 57 squeezes the universal ball through the wedge surface to make the front end of the paper separation platform 58 rotate upward, at this time, the gap between the paper separation platform 58 and the paper picking wheel 51 becomes smaller, and the paper picking wheel 51 can generate a greater paper picking force on the paper, ensuring a better paper conveying effect. Conversely, when the paper picking force of the paper picking wheel 51 on the paper is large, the paper picking force of the paper picking wheel 51 on the paper can be reduced by increasing the gap between the paper separation platform 58 and the paper picking wheel 51.

[0157] Example 6

[0158] On the basis of any one of the embodiments 1-5, in order to improve the accuracy of image acquisition and coding and reduce the working time of the image acquisition device 6 and the coding device 7, this embodiment sets a corresponding detection component on the equipment.

[0159] like Figure 1-5 As shown, the device further includes a paper jam detection component 10, a paper overlap detection component 11, a first sensor 12, a second sensor 13 and a third sensor 14, all of which are connected to the controller.

[0160] The paper jam detection assembly 10 includes photoelectric sensors, which are respectively fixed to the middle of the input end and the middle of the output end of the paper conveying device 5 through the frame 2. When a paper jam occurs during the input process, the paper will protrude upward from the paper support 23, and the light signal between the photoelectric sensors will be blocked, so that the controller can send a paper jam signal.

[0161] The paper overlap detection assembly 11 includes ultrasonic probes, which are respectively fixed to the upper and lower parts of the middle of the input end of the paper conveying device 5 through the frame 2. When the paper enters the input end of the paper conveying device 5, if the paper overlaps, the thickness of the paper will become thicker.
