Description

Technical Field

[0001] This invention relates to document sorting technology, and more specifically to a document sorting device based on automatic identification. Background Technology

[0002] Negotiable instruments are legally binding debt or transaction certificates in economic activities. They are mainly divided into types such as checks, drafts, and promissory notes used for payment and settlement, and invoices and receipts used for document retention. They must include key elements such as the date of issue, a fixed amount, and signatures. When circulating, they must follow the rules of continuous endorsement and accuracy of elements. Enterprises and individuals can choose to use them according to their actual needs, while controlling credit risk and legal validity to avoid invalidity due to issues such as alteration, incomplete elements, or inconsistent signatures.

[0003] To facilitate the management of receipts, a sorting device is needed for their organization and storage. Patent publication number CN221900916U discloses a receipt sorting device, which includes a receipt scanner electrically connected to a camera. The receipt scanner is fixedly connected to a card holder, and a lifter is detachably connected to the card holder. A base is fixedly connected to the bottom of the lifter. A first and second sorting box are slidably installed inside the base, allowing for the categorization and placement of different types of receipts. Different receipts can be placed sequentially on the base, and then the receipt scanner with the camera is adjusted by the lifter to perform scanning. The receipt scanner uses OCR technology, utilizing optical character recognition, to automatically recognize and convert the scanned text into editable digital text. The camera can capture and process headshots, facilitating the management of ticket users. Tickets can be categorized and placed in a first and second sorting box for easier management. While the scanner in the comparison document is height-adjustable, it is only secured by the friction of positioning bolts. Although simple to operate, this method is not stable enough and may cause the scanner to slip during operation, affecting the scanning and sorting process. Secondly, the size of the slot for placing tickets in the comparison document is fixed and cannot be adjusted to accommodate different ticket sizes, making it unsuitable for scanning various sizes of tickets. Furthermore, the internal space of the sorting box for storing tickets is not adjustable, limiting its applicability.

[0004] To address these issues, those skilled in the art have proposed a document sorting device based on automatic identification to resolve the problems raised in the background art. Summary of the Invention

[0026] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] As attached Figure 1 To be continued Figure 7 As shown:

[0028] Example 1:

[0029] This invention provides a document sorting device based on automatic identification, including a mounting base 1. The top of the mounting base 1 has a rectangular placement slot 2. A mounting frame 3 is fixedly connected to one side of the top of the mounting base 1. A scanner 4 for identifying documents and positioned above the placement slot 2 is provided on one side of the mounting frame 3. A lifting component 5 for adjusting the height of the scanner 4 is provided at the connection between the scanner 4 and the mounting frame 3. The lifting component 5 includes a lifting slot 51, a lifting block 52, a screw 53, a rotating slot 54, a rotating shaft 55, a cavity 56, a first sliding groove 57, a connecting groove 58, a pull rod 59, a first slider 510, a first spring 511, a slot 512, a locking block 513, and a pulling block 514. The mounting base 1 has a first empty slot 7 inside. Two sets of storage boxes 8 are provided inside the first empty slot 7. A partition 9 for separating the space of the storage boxes 8 is provided inside the storage boxes 8. Guide rails 11 are provided on both sides of the inner wall of the first empty slot 7. Guide blocks 12 that are slidably connected to the guide rails 11 are fixedly connected to both sides of the storage boxes 8.

[0030] In one embodiment of the present invention, a lifting groove 51 is formed on the side surface of the mounting bracket 3 near the placement groove 2. A lifting block 52 is fixedly connected to the end of the scanner 4 away from the placement groove 2 and slidably connected to the lifting groove 51. The two ends of a screw 53 are respectively rotatably connected to the top and bottom inner walls of the lifting groove 51. The screw 53 passes through and is threadedly connected to the lifting block 52. A rotating groove 54 is formed on the top and bottom inner walls of the lifting groove 51. A rotating shaft 55 is fixedly connected to the top and bottom of the screw 53 and rotatably connected to the rotating groove 54. A cavity 56 is formed inside the top set of rotating shafts 55. A first sliding groove 57 is formed on both sides of the inner walls of the cavity 56. A connecting groove 58 passes through the top. A set of rotating grooves 54 are connected to the top inner wall of the cavity 56. A pull rod 59 is movably connected to the connecting groove 58 and extends to the inside of the cavity 56. A first slider 510 is fixedly connected to the bottom of the pull rod 59 and slidably connected to the cavity 56 and the first sliding groove 57. A first spring 511 is sleeved on the outer periphery of the pull rod 59 near the bottom and its two ends are fixedly connected to the top of the first slider 510 and the top inner wall of the cavity 56, respectively. Several sets of slots 512 are provided and are distributed in a ring on the top outer periphery of the connecting groove 58. A locking block 513 is fixedly connected to the outer periphery of the pull rod 59 near the top and is adapted to the size of the slot 512. A pull block 514 is fixedly connected to the top of the pull rod 59.

[0031] Working principle: When sorting tickets, first place the tickets in the placement slot 2, then start the scanner 4 to scan them. After scanning, remove the storage box 8 from the first empty slot 7. During this process, the guide block 12 moves synchronously along the guide rail 11 with the storage box 8 and limits and guides it. Then, the tickets are placed in the storage box 8 for storage. When it is necessary to scan tickets of different sizes, pull the pull block 514 upward so that it drives the first slider 510 to slide upward along the first slide groove 57 through the pull rod 59 and squeeze the first spring 511. When the locking block 513 moves upward with the pull rod 59 and moves out of the locking slot 512, rotate the pull rod 59 so that it drives the first slider 510 to rotate synchronously. Since the first slider 510 is slidably connected to the cavity 56 and the first slide groove 57 and the first spring 511 is also slidably connected, the first slider 510 rotates synchronously. A slide groove 57 is formed on both sides of the inner wall of the cavity 56. Therefore, the first slider 510 will drive a set of rotating shafts 55 at the top to rotate synchronously with the pull rod 59, thereby driving the screw 53 to rotate. Since the screw 53 passes through and is threadedly connected to the lifting block 52, the lifting block 52 will move up and down along the lifting groove 51 as the screw 53 rotates, thereby adjusting the height of the scanner 4. After adjusting to the appropriate height, the pull block 514 is released, the first spring 511 rebounds and drives the pull rod 59 to move downward through the first slider 510. When the locking block 513 moves downward with the pull rod 59 to the insertion slot 512, the pull rod 59 can be fixed at the current angle, thereby fixing the lifting block 52 at the current height, thus completing the height adjustment of the scanner 4. At this time, the scanning and sorting of documents of different sizes can be performed.

[0032] Example 2:

[0033] This embodiment is basically the same as the previous embodiment, except that the placement slot 2 is provided with a limiting component 6 for limiting the ticket. The limiting component 6 includes a second empty slot 61, a through slot 62, a top rod 63, a limiting block 64, a rotating ring 65, an arc block 66, an extension slot 67, a gear 68, a locking tooth 69, a second sliding groove 610, a second slider 611, and a second spring 612.

[0034] In one embodiment of the present invention, a second slot 61 is formed inside the mounting base 1 and located on the outer periphery of the placement slot 2. A through slot 62 penetrates the inner wall of the second slot 61 near the placement slot 2. A push rod 63 is slidably connected to the through slot 62. A limiting block 64 is fixedly connected to one end of the push rod 63 located in the placement slot 2. A rotating ring 65 is rotatably connected to the second slot 61. An arc-shaped block 66 is fixedly connected to the side of the rotating ring 65 near the placement slot 2. The contact surfaces of the arc-shaped block 66 and the push rod 63 are both fan-shaped. An extension slot 67 is formed on one side of the second slot 61 and is connected to a set of rotating slots 54 at the bottom. The gear 68 is fixedly connected to the bottom of a set of rotating shafts 55 and rotatably connected to the extension groove 67. The snap tooth 69 is fixedly connected to the outer circumference of the rotating ring 65 and meshes with the gear 68. The second slide groove 610 is opened on the bottom inner wall of the second empty groove 61 and is located below the top rod 63. The second slider 611 is fixedly connected to the bottom of the top rod 63 and slidably connected to the second slide groove 610. The second spring 612 is installed inside the second slide groove 610 and its two ends are respectively fixedly connected to the inner wall of the second slider 611 near the placement groove 2 and the second slide groove 610 near the placement groove 2.

[0035] Working principle: During the process of the screw 53 rotating and driving the scanner 4 upward, a set of rotating shafts 55 at the bottom will drive the gear 68 to rotate synchronously with the screw 53. Since the retaining tooth 69 meshes with the gear 68, the rotating ring 65 will drive the arc block 66 to rotate with the rotation of the gear 68. When the arc block 66 moves away from the back of the top rod 63, the second spring 612 rebounds and drives the top rod 63 and the limiting block 64 to move into the second slot 61 through the second slider 611, thereby increasing the distance between the limiting blocks 64, so that it can handle larger tickets. According to the limit setting, when the screw 53 stops rotating, the rotating ring 65 and the arc block 66 are fixed in the current position, so that the limit block 64 maintains the current spacing. When the screw 53 drives the scanner 4 to descend, the rotating ring 65 will drive the arc block 66 to rotate in the opposite direction. When the arc block 66 contacts the top rod 63, the arc block 66 will push the top rod 63 and the limit block 64 towards the placement groove 2 and squeeze the second spring 612 through the second slider 611. At this time, the spacing of the limit blocks 64 is reduced, thereby enabling the limit setting of smaller tickets.

[0036] Example 3:

[0037] This embodiment is basically the same as the previous embodiment, except that an adjustment component 10 for adjusting the position of the partition 9 is provided at the connection between the partition 9 and the storage box 8. The adjustment component 10 includes an adjustment groove 101, an adjustment block 102, a groove 103, a fixing hole 104, a pull plate 105, a fixing rod 106, a third sliding groove 107, a vertical groove 108, a vertical rod 109, a third slider 1010, and a third spring 1011.

[0038] In one embodiment of the present invention, the adjusting groove 101 is formed on the inner walls of both sides of the storage box 8, the adjusting block 102 is fixedly connected to both sides of the partition 9 and slidably connected to the adjusting groove 101, the groove 103 is formed on both sides of the top of the storage box 8, a plurality of fixing holes 104 are provided and formed on the inner wall of the bottom of the groove 103, the pull plate 105 is movably connected to the top of the partition 9 and is adapted to the size of the groove 103, and the fixing rod 106 is fixedly connected to both sides of the bottom of the pull plate 105 and is adapted to the size of the fixing hole 104. The third slide groove 107 is opened inside the partition plate 9, the vertical groove 108 passes through the top inner wall of the third slide groove 107, the vertical rod 109 is fixedly connected to the bottom center of the pull plate 105 and extends through the vertical groove 108 into the third slide groove 107, the third slider 1010 is fixedly connected to the bottom of the vertical rod 109 and slidably connected to the third slide groove 107, and the third spring 1011 is sleeved on the outer periphery of the vertical rod 109 and its two ends are respectively fixedly connected to the top of the third slider 1010 and the top inner wall of the third slide groove 107.

[0039] Working principle: When it is necessary to adjust the size of the internal space of the storage box 8, pull the pull plate 105 upward so that it drives the third slider 1010 to slide upward along the third slide groove 107 via the vertical rod 109 and compress the third spring 1011. When the fixing rod 106 moves upward with the pull plate 105 and moves out of the fixing hole 104, slide the adjusting block 102 along the adjusting groove 101 so that it drives the partition 9 to move synchronously. When the partition 9 moves to the appropriate position, release the pull plate 105. The third spring 1011 rebounds and drives the pull plate 105 downward through the third slider 1010 and the vertical rod 109. When the fixing rod 106 moves downward with the pull plate 105 and inserts into the fixing hole 104 at the current position, the partition 9 can be fixed in the current position, thereby completing the adjustment of the internal space of the storage box 8.
