Description

Technical Field

[0001] This application relates to the technical field of document loading, and in particular to a document loading device. Background Technology

[0002] With the rapid development of the logistics industry, the volume of express delivery business has experienced explosive growth. As a key carrier for protecting document privacy and security, the efficiency of the filling process of express document envelopes directly affects the overall process rhythm of express sorting, transfer and delivery.

[0003] Currently, the loading of express delivery documents mainly relies on manual labor. Operators need to first take the express delivery documents from the document stack, then manually open the seal of the document, and finally put the express delivery documents into the document seal through the seal. This loading operation requires operators to do repetitive work for a long time, which is inefficient and has high labor costs. Utility Model Content

[0004] Therefore, it is necessary to provide a document loading device to address the problems of low efficiency and high labor costs in the loading of express documents in traditional technologies.

[0005] The technical solution is as follows:

[0006] One embodiment provides a document loading apparatus, comprising:

[0007] An opening and closing mechanism includes a first adsorption member, a second adsorption member, a cap adsorption member, a first moving member, and a first rotating member. The first adsorption member is used to adsorb or release a first surface of the cap. The second adsorption member is disposed on the first moving member and is used to adsorb or release a second surface of the cap. The first moving member can move the second adsorption member closer to or away from the second surface. The cap adsorption member is disposed on the first rotating member and is used to adsorb or release the cap. The first rotating member can drive the second adsorption member to rotate around the rotation axis of the cap.

[0008] A push mechanism for placing files, the push mechanism being able to move in and out of the envelope.

[0009] In the aforementioned document loading device, during use, the first adsorption member adsorbs and positions the first surface of the envelope. The first moving member drives the second adsorption member to approach the second surface of the envelope, enabling the second adsorption member to adsorb and position the second surface of the envelope. The first rotating member drives the second adsorption member to rotate around the rotation axis of the cover, allowing the second adsorption member to adsorb and position the cover. Subsequently, the first rotating member drives the second adsorption member to rotate in the opposite direction, thereby causing the cover to rotate and open the seal of the envelope. At this time, the first moving member drives the second adsorption member to move away from the second surface of the envelope. Under the adsorption action of the second adsorption member, the second surface moves away from the first surface, thereby widening the seal. The document-push mechanism moves and sends the document through the seal into the envelope, thus achieving document loading. Compared with traditional technology, the aforementioned document loading device does not require manual labor by workers, has high loading efficiency, and can reduce labor costs.

[0047] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0048] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0049] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0050] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0051] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0052] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0053] Please see Figures 12 to 14 Document envelope 10 typically consists of a sleeve 11 and a cover 12. The sleeve 11 has a slit 15 on one side and a first surface 13 and a second surface 14 facing away from each other. The slit 15 is used for documents to enter and exit the document envelope 10. The cover 12 is located on one side of the sleeve 11 and can move to open and close the slit 15. In traditional technology, workers usually need to manually open the cover 12 and move the first surface 13 away from the second surface 14 to open the slit 15 wider. Then, the documents are put into the sleeve 11 from the slit 15. Long-term repetitive labor leads to low operational efficiency and high labor costs.

[0054] Please see Figures 1 to 5 as well as Figure 7 One embodiment of this application provides a document loading device, including an opening and closing mechanism 200 and a pushing mechanism 300. The opening and closing mechanism 200 includes a first adsorption member 210, a second adsorption member 220, a cap adsorption member 230, a first moving member 240, and a first rotating member 250. The first adsorption member 210 is used to adsorb or release the first surface 13 of the cover 11. The second adsorption member 220 is disposed on the first moving member 240 and is used to adsorb or release the second surface 14 of the cover 11. The first moving member 240 can drive the second adsorption member 220 to move closer to or away from the second surface 14. The cap adsorption member 230 is disposed on the first rotating member 250 and is used to adsorb or release the cap 12. The first rotating member 250 can drive the second adsorption member 220 to rotate around the rotation axis of the cap 12. The pushing mechanism 300 is used to place documents and can move in and out of the cover 11.

[0055] In use, the aforementioned document loading device employs the following steps: the first adsorption member 210 adsorbs and positions the first surface 13 of the cover 11; the first moving member 240 moves the second adsorption member 220 closer to the second surface 14 of the cover 11, enabling the second adsorption member 220 to adsorb and position the second surface 14 of the cover 11; the first rotating member 250 rotates the second adsorption member 220 around the rotation axis of the cover 12, allowing the second adsorption member 220 to adsorb and position the cover 12; subsequently, the first rotating member 250 rotates the second adsorption member 220 in the opposite direction, thereby moving the cover 12... The cover 12 rotates and opens the seal 15 of the cover 11. At this time, the first moving part 240 drives the second adsorption part 220 to move away from the second surface 14 of the cover 11. Under the adsorption of the second adsorption part 220, the second surface 14 moves away from the first surface 13, thereby opening the seal 15 wider. The push mechanism 300, which holds the document, moves and sends the document through the seal 15 into the cover 11 to achieve document loading. Compared with traditional technology, the above-mentioned document loading device does not rely on manual labor by workers, has high loading efficiency, and can reduce labor costs.

[0056] For explanation, please refer to Figure 12 and Figure 13 The cap 12 is rotatably connected to one side of the sleeve 11. The axis of rotation of the cap 12 is the straight line on the side where the sleeve 11 and the cap 12 are connected. This will not be elaborated further here.

[0057] Furthermore, in the above embodiment, the first surface 13 of the cover 11 is the lower surface, and the second surface 14 of the cover 11 is the upper surface. Under the action of the first adsorption member 210 and the second adsorption member 220, the upper and lower surfaces of the cover 11 are separated from each other, thereby opening the seal 15 to make it easier for the pushing mechanism 300 to send the document from the seal 15 into the document cover 10.

[0058] Optionally, the first adsorption element 210, the second adsorption element 220, the capping adsorption element 230, and the fourth adsorption element to be mentioned below can be rubber suction cups or negative pressure vacuum suction cups, etc., without specific limitations here.

[0059] Preferably, the first adsorption element 210, the second adsorption element 220, the capping adsorption element 230, and the fourth adsorption element (described below) are all negative pressure vacuum suction cups. This allows adsorption or release to be achieved by adjusting the pressure of the negative pressure vacuum suction cups, resulting in low implementation cost and reliable adsorption effect. Taking the first adsorption element 210 as an example, when adsorption is needed on the first surface 13 of the capping sleeve 11, the first adsorption element 210 is controlled to a negative pressure state; when release is needed on the first surface 13 of the capping sleeve 11, the first adsorption element 210 is controlled to a normal pressure state. The second adsorption element 220 and the capping adsorption element 230 are similar to the first adsorption element 210, and will not be described further here.

[0060] Please see Figures 6 to 7 In one embodiment, the document loading device further includes a frame 100, a first adsorption member 210, a first moving member 240 and a first rotating member 250 are all disposed on the frame 100, a pushing mechanism 300 is movably disposed on the frame 100, and an opening and closing mechanism 200 further includes a support platform 260, which is disposed on the frame 100 and used to support the second surface 14. The document loading device further includes a pressing mechanism, which includes a pressing member 410 and a second moving member 420. The pressing member 410 is disposed on the second moving member 420, and the second moving member 420 is disposed on the frame 100 and used to drive the pressing member 410 to press or release the first surface 13.

[0061] The frame 100 is used to integrate multiple mechanisms to improve the compactness of the document loading device; the support platform 260 is used to support the second surface 14 of the envelope 11. After the pushing mechanism 300 pushes the document into the envelope 11, the second moving part 420 drives the pressing part 410 to press against the first surface 13, so as to press the document in the envelope 11 through the first surface 13. Then, the pushing mechanism 300 exits the envelope 11 from the seal 15, and the document remains in the envelope 11 due to the pressure from the pressing part 410, so as to prevent the pushing mechanism 300 from taking the document out when exiting the envelope 11, which would cause the document loading to fail and improve the practicality of the document loading device.

[0062] Further, as described in the above embodiments, the first surface 13 is the upper surface of the cover 11, and the second surface 14 is the lower surface of the cover 11. Based on this, the support platform 260 is arranged below the cover 11 and is used to support the document cover 10. The pressing member 410 and the second adsorption member 220 are both arranged above the support platform 260 to press and adsorb the second surface 14 of the cover 11 respectively.

[0063] Please see Figure 6 In one embodiment, the pushing mechanism 300 includes a pushing member 310 and a third moving member 320. The pushing member 310 is disposed on the third moving member 320, and the third moving member 320 is disposed on the frame 100 and can drive the pushing member 310 in and out of the cover 11. The pushing member 310 has an avoidance notch 312.

[0064] When the pusher 310 enters the cover 11, the position of the clearance notch 312 is opposite to the position of the clamping member 410.

[0065] By using the clearance notch 312 positioned opposite to the clamping member 410, when the clamping member 410 presses against the first surface 13 of the cover 11, it will not squeeze the pushing member 310. The pressure of the clamping member 410 is directly transmitted to the second surface 14 through the clearance notch 312, so that after the pushing member 310 pushes the document into the cover 11, it can smoothly exit from the cover 11 under the action of the third moving member 320 without being pressed by the clamping member 410. This avoids the clamping member 410 affecting the movement of the pushing member 310 and prevents damage to the document.

[0066] Please see Figures 4 to 7 In one embodiment, the third moving member 320 drives the pusher 310 to reciprocate along the length of the frame 100. Correspondingly, the clearance notch 312 is also opened along the length of the frame 100 and faces the clamping member 410 to clear the pusher 310 and avoid affecting the movement of the pusher 310.

[0067] Please see Figure 6 In one embodiment, the pusher 310 includes a push platform 311 and a folding module 600, the push platform 311 and the folding module 600 being spaced apart along a first direction of the pusher 310 to form a clearance gap 313.

[0068] The document loading device also includes a document feeding mechanism 500, which has a document feeding position 511. The clearance gap 313 has an opening on one side along its own length direction facing the document feeding position 511, and an opening on the other side along its own length direction facing the opening and closing mechanism 200.

[0069] The pushing mechanism 300 also includes a clamping member 330, which is disposed on the frame 100 and at least partially located within the clearance gap 313. The clamping member 330 can reciprocate along the length direction of the clearance gap 313 and is used to clamp or release the document. The folding module 600 is used to fold the document during the process of the document moving from the document loading position 511 to the pushing table 311.

[0070] The clamping component 330 moves within the clearance gap 313, holding the folder on the document loading position 511 and releasing it on the pusher table 311. The clearance gap 313 provides space for the movement of the clamping component 330, so that it can fit as close as possible to the pusher table 311 during the clamping and moving process. This allows the folding module 600, which is spaced apart from the pusher table 311, to fold the document, avoiding the phenomenon that the document area is larger than the size of the seal 15 and cannot be sent into the cover 11 through the pusher table 311.

[0071] Furthermore, the clamping component 330 is a gripper with its gripping opening facing the document loading position 511, so that the gripper can directly clamp the document when it moves to the document loading position 511. Then it moves along the length direction of the clearance gap 313 to transport the document to the push table 311. During the transport process, the folding module 600 folds the document to prevent the document from being too large to enter the cover 11.

[0072] For explanation purposes, the first direction of the pusher 310 is the width direction of the pusher 310, that is... Figure 6 In direction A, the width direction of the pusher 310 is parallel to the width direction of the frame 100 and perpendicular to the length direction of the frame 100, which will not be elaborated here.

[0073] Please see Figure 1 , Figure 10 and Figure 11 In one embodiment, the document feeding mechanism 500 further includes a receiving platform 510, which is located on the frame 100 and used to dock with the preceding equipment. The receiving platform 510 is provided with a docking position 512 and a document feeding position 511. The docking position 512 is used to receive documents sent from the preceding equipment, such as a single A4 sheet, several bound A4 sheets, or a laminated A4 document.

[0074] Furthermore, limit plates 513 are provided on both sides of the docking position 512 to prevent the documents transported by the preceding equipment from shifting at the receiving table 510.

[0075] Please see Figure 10 and Figure 11 In one embodiment, the document feeding mechanism 500 further includes a document recognition sensor, which is located on the frame 100. The receiving table 510 has a circular hole 521, and the document recognition sensor is arranged below the circular hole 521. When a document arrives at the receiving table 510, the document recognition sensor determines whether the document is qualified.

[0076] Furthermore, the document loading mechanism 500 also includes a first position sensor 522, a second position sensor 523, a fifth moving member 530, a loading gripper 540, and a recycling box 550. The first position sensor 522 is located on the frame 100. The loading gripper 540 is located on the fifth moving member 530 and is used to grip or release documents. The fifth moving member 530 is movably located on the frame 100 and is used to drive the loading gripper 540 to move so that the documents can be connected to the docking position 512 through the loading gripper 540 and released after being transported to the document loading position 511. The first position sensor 522 will identify whether the document has reached the docking position 512. When the document reaches the docking position 512, the first position sensor 523 identifies that the document is in place, and the fifth moving member 530... The fifth moving part 530 moves the feeding gripper 540 to clamp the document. The fifth moving part 530 moves the feeding gripper 540 to the document feeding position 511. The second position sensor 523 is located at the document feeding position 511. The second position sensor 523 is used to identify whether there is a document at the document feeding position 511. When the second position sensor 523 identifies that there is a document at the document feeding position 511, the clamping part 330 will determine whether the document is qualified based on the information from the document identification sensor. If it is qualified, the clamping part 330 will move the document at the document feeding position 511 to the pusher 310. If it is not qualified, the feeding gripper 540 will open and release the document. The fifth moving part 530 will move the feeding gripper 540 upward, and the clamping part 330 will push the unqualified document into the recycling box 550.

[0077] Furthermore, a connecting slope 560 is provided on the side of the document loading position 511 away from the pusher 310. The connecting slope 560 is used to connect the document loading position 511 and the recycling box 550 to achieve effective recycling of unqualified documents.

[0078] Please see Figure 1 , Figure 11 and Figure 12 In one embodiment, the receiving platform 510 is vertically mounted on the frame 100 to accommodate different docking heights of the preceding equipment.

[0079] Furthermore, the receiving platform 510 has a first ramp 514 and a second ramp 515. The first ramp 514 is used to compensate for the height difference between the docking position 512 and the gripper, so as to ensure that the loading gripper 540 can accurately hold the document at the receiving position. The second ramp 515 is used to compensate for the height difference between the document loading position 511 and the docking position 512.

[0080] Furthermore, the inclination of the first ramp 514 and the inclination of the second ramp 515 are both adjustable. By adjusting the inclination of the first ramp 514, it is ensured that the document at the docking position 512 can be accurately gripped by the loading jaw 540. Since the height of the document loading position 511 needs to match the height of the pusher 310, and the height of the document loading position 511 also needs to match the different heights of the pusher 310 under different usage environments, by adjusting the inclination of the second ramp 515, the docking of the document loading position 511 and the receiving position can be realized to carry the document transport.

[0081] Please see Figure 4 In one embodiment, the pushing mechanism 300 further includes a pushing sensor 340, which is located on the frame 100 and is used to detect whether the document is conveyed to the designated position of the pushing table by the clamping member 330. If the document reaches the designated position, the pushing table will carry the document into the opened document seal 10.

[0082] Please see Figure 6 In one embodiment, the folding module 600 includes a folding table 610, a first folding member 620, and a second folding member 630. The folding table 610 is disposed on the third moving member 320 and has a first folding position 611 and a second folding position 612. The second folding position 612 is disposed on the side of the first folding position 611 away from the document loading position 511. The first folding member 620 is disposed on the first folding position 611 and protrudes along the second direction of the pusher 310. The second direction forms an angle with the first direction. The side of the first folding member 620 away from the folding table 610 is set at an angle with the folding table 610. The second folding member 630 is disposed on the second folding position 612. The second folding member 630 is spaced apart from the folding table 610 along the second direction to form a folding channel 631. The side of the second folding member 630 facing the first folding position 611 forms an angle with the length direction of the clearance gap 313.

[0083] As the document moves from the document loading position 511 to the push table 311 via the clamping member 330, the side of the document will pass through the first folding position 611 and the second folding position 612 in sequence. When the side of the document passes through the first folding position 611, under the action of the side of the first folding member 620 away from the folding table 610, the side of the document will gradually stand up. Then, when passing through the second folding position 612, under the action of the side of the second folding position 612 facing the first folding position 611, the side of the document will bend towards the push table 311 and finally enter the folding channel 631 to complete the folding. The implementation cost is low and the folding effect is reliable.

[0084] Further, please refer to Figure 6The first folding piece 620 is triangular, and the hypotenuse of the first folding piece 620 is at an angle to the folding table 610, so as to drive the side of the document to gradually stand up; the second folding piece 630 is trapezoidal, and one hypotenuse of the trapezoid is facing the first folding piece 620 and at an angle to the length direction of the clearance gap 313, so as to drive the side of the upright document cover 10 to bend towards the push table 311.

[0085] For illustrative purposes, the second direction of the pusher 310 is the thickness direction of the push stage 311, that is... Figure 6 In direction B, the width direction of the pusher 310 is parallel to the height direction of the frame 100 and perpendicular to the length direction of the frame 100, which will not be elaborated here.

[0086] Please see Figure 6 In one embodiment, the folding module 600 further includes a folding pressing block 640, which is disposed on the third moving member 320 and spaced apart from the first folding position 611 along the second direction, and the folding pressing block 640 and the first folding member 620 are spaced apart along the first direction.

[0087] The folding block 640 prevents the side of the document from being unable to be folded by the first folding piece 620 due to warping. The side of the document can enter through the gap between the folding block 640 and the first folding position 611. Under the action of the gap between the folding block 640 and the first folding piece 620, the side of the document can be gradually raised, improving the success rate of the folding process.

[0088] Furthermore, the folding block 640 is tilted upwards toward the side of the document feeding position 511 to ensure that the side of the document can enter the gap between the folding block 640 and the first folding position 611.

[0089] Please see Figure 6 As an embodiment that can be implemented simultaneously or separately with the above embodiments, two folding modules 600 are provided, one of which is located on one side of the push platform 311 along the first direction, and the other is located on the other side of the push platform 311 along the first direction.

[0090] This setting allows for simultaneous folding of both sides of the file to prevent the file from being too large to fit into envelope 11.

[0091] Understandably, the folding module 600 is provided in two and is respectively provided on opposite sides of the push platform 311 along the first direction to form two clearance gaps 313. The clamping member 330 is provided in two and is set one-to-one with the two clearance gaps 313.

[0092] Please see Figures 1 to 3 as well as Figure 8 and Figure 9In one embodiment, the document loading device further includes a document cover storage mechanism 700 and a document cover feeding mechanism 800. Both the document cover storage mechanism 700 and the document cover feeding mechanism 800 are located on the frame 100. The document cover storage mechanism 700 is provided with a storage position 711 for storing document covers 10. The document cover feeding mechanism 800 is used to transport the document covers 10 located in the storage position 711 to the carrier platform 260.

[0093] The storage position 711 of the document sealing storage mechanism 700 is used to store document sealing 10, and the document sealing feeding mechanism 800 is used to transport the document sealing 10 in the storage position 711 to the carrier stage 260 for subsequent document loading. This configuration enables the document loading device to achieve continuous document loading and improve document loading efficiency.

[0094] Please see Figure 3 In one embodiment, the rack 100 includes a first frame 110, a second frame 120 and a third frame 130, an opening and closing mechanism 200 and a pushing mechanism 300 are disposed on the first frame 110, a document feeding mechanism 500 is disposed on the second frame 120, and a document sealing storage mechanism 700 and a document sealing feeding mechanism 800 are disposed on the third frame 130.

[0095] Further, please refer to Figure 3 The second frame 120 is located on one side of the length direction of the first frame 110, and the third frame 130 is located on one side of the width direction of the first frame 110. It is understood that this application is not limited thereto, and the placement of the first frame 110, the second frame 120 and the third frame 130 can be flexibly adjusted according to the site conditions, which will not be elaborated here.

[0096] For explanation, the length direction of the first frame 110 is... Figure 3 In the x-direction, the width direction of the first frame 110 is... Figure 3 y direction in .

[0097] Please see Figures 8 to 9 In one embodiment, the document envelope storage mechanism 700 includes a mounting base 720 and a lifting platform 710. The mounting base 720 is disposed on the frame 100, and the lifting platform 710 is disposed on the mounting base 720 and has a storage position 711. The document envelope feeding mechanism 800 includes a third adsorption member 810 and a fourth moving member 820. The third adsorption member 810 is disposed on the fourth moving member 820 and is used to adsorb or release the document envelope 10. The fourth moving member 820 is disposed on the frame 100 and can drive the third adsorption member 810 to reciprocate between the storage position 711 and the support platform 260.

[0098] The storage position 711 of the lifting platform 710 can stack and store multiple document envelopes 10. The lifting platform 710 can be raised and lowered on the mounting base 720. When the fourth moving member 820 drives the third adsorption member 810 to transport the document envelope 10 located at the top of the storage position 711 to the carrier platform 260, the lifting platform 710 rises, causing the document envelope 10 currently located at the top of the storage position 711 to rise. This ensures that the fourth moving member 820 can reliably adsorb the document envelope 10 when it drives the third adsorption member 810 back to the storage position 711, avoiding the impact on the conveying efficiency of the document envelope 10 due to the third adsorption member 810 not being accurately aligned with the document envelope 10.

[0099] Further, please refer to Figures 8 to 9 The document envelope storage mechanism 700 also includes a third position sensor 730, which is located on the mounting base 720 and electrically connected to the lifting platform 710. When the top of the document envelope 10 in the storage position 711 reaches a specified height, the third position sensor 730 is triggered, and the lifting platform 710 stops rising, so as to ensure that the fourth moving member 820 can reliably adsorb the document envelope 10 when it drives the third adsorption member 810 back to the storage position 711.

[0100] Please see Figures 8 to 9 In one embodiment, the document sealing storage mechanism 700 further includes a limiting rod 740. The limiting rod 740 is provided with at least two and is arranged at intervals along the circumference of the lifting platform 710 on the mounting base 720. The fourth moving member 820 includes a telescopic part 821. The third adsorption member 810 is provided on the telescopic part 821. The telescopic part 821 is used to drive the third adsorption member 810 and the document sealing 10 to reciprocate along the axial direction of the limiting rod 740.

[0101] The limiting rods 740, which are spaced circumferentially along the lifting platform 710, can limit the document envelopes 10 located in the storage position 711 to prevent the stacked document envelopes 10 from tilting or falling over. The telescopic part 821 can drive the third suction member 810 to move along the axial direction of the limiting rods 740 to remove the document envelopes 10 in the storage position 711 from above the limiting rods 740. In this way, the stacked document envelopes 10 can be limited without affecting the delivery of the document envelopes 10, thereby improving the ease of use of the document loading device.

[0102] Please see Figures 8 to 9 In one embodiment, the document cover storage mechanism 700 further includes a stop 750, which is disposed on the limiting rod 740 and is used to be located on the movement path of the document cover 10 when it moves away from the storage position 711.

[0103] During the process of the telescopic part 821 driving the third adsorption member 810 and the document seal 10 to move along the axial direction of the limiting rod 740, the stop block 750 can block the edge of the document seal 10, causing the document seal 10 to bend, preventing two or more document seals 10 that are stuck together from being taken out from above the limiting rod 740 at the same time, preventing the document loading device from malfunctioning and improving the operational reliability of the document loading device.

[0104] Further, please refer to Figures 8 to 9 Two blocks 750 are provided. The two blocks 750 are used to block the two opposite sides of the document cover 10, so as to further prevent two or more document covers 10 that are stuck together from being taken out at the same time.

[0105] Understandably, in other embodiments, there may be more than two stop blocks 750, which can be flexibly set according to the number of limit rods 740 and the actual working conditions, and will not be elaborated here.

[0106] Please see Figure 8 In one embodiment, the fourth moving member 820 further includes a translation part 822, which is connected to the telescopic part 821 and can drive the telescopic part 821 to translate. In use, the translation part 822 drives the telescopic part 821, which is equipped with the third suction member 810, to translate directly above the storage position 711. The telescopic part 821 extends and drives the third suction member 810 to descend. The third suction member 810 contacts the document cover 10 and sucks in the document cover 10. After the document cover 10 is sucked in, it undergoes a "lift-fall-lift" process. This process is very fast and realizes the document cover 10's... The document cover 10 is shaken to prevent it from sticking together. Then the document cover 10 rises and passes through the stop 750. The stop 750 blocks the edge of the document cover 10 during its rise, causing it to bend. This further prevents two or more document covers 10 that are stuck together from being taken out from above the limit rod 740 at the same time. After the uppermost document cover 10 is taken out, the lifting platform 710 will rise a certain distance, which will trigger the third position sensor 730 to ensure that the height of the document cover 10 is consistent each time it is picked up.

[0107] In one embodiment, a material shortage sensor 760 is provided below the lifting platform 710. When the last document cover 10 in the storage position 711 is sucked away, the material shortage sensor 760 is triggered. At this time, the lifting platform 710 is lowered to the lowest position, waiting for manual filling of the document cover 10.

[0108] Please see Figure 8In one embodiment, the file storage mechanism further includes a ball screw module 771, a support shaft 772, a drive motor 773, and a mounting plate 774. The mounting plate 774 is disposed on the frame 100 and arranged below the mounting base 720. The drive motor 773 is driven and connected to one end of the ball screw module 771 via a synchronous belt to drive the ball screw module 771 to rotate. The other end of the ball screw module 771 passes through the mounting base 720 and is connected to the lifting platform 710. The ball screw module 771 converts the rotational motion into linear motion, thereby driving the lifting platform 710 to lift. One end of the support shaft 772 is connected to the mounting plate 774, and the other end passes through the mounting base 720 and is connected to the lifting platform 710 to improve the lifting stability of the lifting platform 710.

[0109] Furthermore, the drive motor 773 is mounted on the mounting plate 774 below the mounting base 720, thereby effectively saving space and improving the compactness of the document loading device.

[0110] Please see Figures 8 to 9 In one embodiment, the document storage mechanism 700 further includes a first guide 781 and a second guide 782, which are spaced apart from each other on the mounting base 720 to form a feeding window 785 between the first guide 781 and the second guide 782. The feeding window 785 communicates with the storage position 711. The first guide 781 is provided with a first guide slope, and the second guide 782 is provided with a second guide slope. The plane where the first guide slope is located is set at an angle to the plane where the second guide slope is located. At least one limiting rod 740 is detachably provided at the feeding window 785.

[0111] When staff need to replenish document cover 10 to storage position 711 through replenishment window 785, the first guide ramp and the second guide ramp set at replenishment window 785 can provide a guiding function for the movement of document cover 10 at replenishment window 785, reduce the difficulty of alignment between replenishment windows 785 of document cover 10, and simplify the operation process.

[0112] Please see Figures 8 to 9 In one embodiment, the document cover storage mechanism 700 further includes a third guide 783 and a fourth guide 784, which are located on opposite sides of the storage position 711. The third guide 783 has a third guide ramp, and the fourth guide 784 has a fourth guide ramp. The plane containing the third guide ramp and the plane containing the fourth guide ramp are set at an angle to further guide the side of the document cover 10 that enters or exits the storage position 711 from the replenishment window 785, thereby simplifying the operation process when replenishing the document cover 10.

[0113] Please see Figures 8 to 9In one embodiment, eight limiting rods 740 are provided. The eight limiting rods 740 are arranged at intervals along the circumference of the lifting platform 710 on the mounting base 720. The eight limiting rods 740 are arranged in pairs. Each group of limiting rods 740 is used to limit a corner of the document cover 10, so as to effectively limit the stacked document covers 10.

[0114] Furthermore, the first guide 781, the second guide 782, the third guide 783, and the fourth guide 784 are respectively disposed on one of the limiting rods 740 in each group of limiting rods 740. The first guide 781 and the second guide 782 are spaced apart along the width direction of the document cover 10, and the third guide 783 and the fourth guide 784 are spaced apart along the width direction of the document cover 10.

[0115] exist Figure 8 and Figure 9 In the embodiment shown, the stop 750 is provided with two stop blocks and is respectively provided on two limiting rods 740 that are arranged opposite each other along the length direction of the document cover 10, so as to prevent two or more document covers 10 that are stuck together from being taken out at the same time.

[0116] Please see Figures 8 to 9 In one embodiment, the document seal storage mechanism 700 further includes a tube clamp 790, a limiting rod 740 disposed in the tube clamp 790, and a mounting base 720 provided with a sliding groove 721. The tube clamp 790 is slidably disposed in the sliding groove 721 of the mounting base 720. The gap between the limiting rod 740 and the document seal 10 is adjusted by sliding the tube clamp 790 in the sliding groove 721, so that the limiting rod 740 can restrict the position of the document seal 10 without being over-clamped and causing the document seal 10 to be unable to be taken out.

[0117] Further, please refer to Figures 8 to 9 Two pipe clamps 790 located at the replenishment window 785 are detachably installed in the slide groove 721. When it is necessary to replenish the document cover 10 through the replenishment window 785, the two pipe clamps 790 located at the replenishment window 785 are first removed, and then the document cover 10 is placed from the replenishment window 785 into the storage position 711. The first guide 781, the second guide 782, the third guide 783 and the fourth guide 784 provide guidance for the filling of the document cover 10. The limit rod 740 has an upper limit mark to indicate the highest position of the document cover 10 that can be filled into the storage position 711. After the document cover 10 is filled, the removed pipe clamps 790 are reinstalled to complete the replenishment of the document cover 10.

[0118] Please see Figures 8 to 9In one embodiment, there are two file cover storage mechanisms 700. One file cover storage mechanism 700 is used to supply the current file filling process, and the other file cover storage mechanism 700 is used as a backup supply after the file cover 10 of the previous file cover storage mechanism 700 is consumed. At the same time, it can replenish the file cover 10 of the empty file cover storage mechanism 700 so as to achieve the replenishment of file cover 10 without stopping the machine and improve the file filling efficiency.

[0119] Please see Figure 8 In one embodiment, the document sealing feeding mechanism 800 further includes an orientation recognition sensor 830, which is disposed on the frame 100 and is used to identify the sealing orientation of the document seal 10 on the third adsorption member 810. The document sealing feeding mechanism 800 also includes a second rotating member 840, which is disposed on the fourth moving member 820 and connected to the third adsorption member 810. The second rotating member 840 is electrically connected to the orientation recognition sensor 830 and is used to drive the third adsorption member 810 to rotate.

[0120] Please see Figure 14 Since the thickness of the side of the document envelope 10 with the cap 12 is greater than the thickness of the side without the cap 12, the document envelopes 10 need to be stacked in an alternating manner to ensure the flatness of the top surface after stacking. The sealing orientation of the document envelopes 10 when they reach the support platform 260 must be uniform. An incorrect sealing orientation will prevent the cap 12 from opening. Therefore, the document envelopes 10 with incorrect sealing orientation need to be adjusted to the correct sealing orientation. The orientation recognition sensor 830 is used to identify the sealing orientation of the document envelopes 10. When it detects that the sealing orientation of the document envelopes 10 is incorrect, it sends a command to the second rotating member 840 and drives the third adsorption member 810 and the document envelopes 10 on the third adsorption member 810 to rotate together, thereby adjusting the document envelopes 10 to the correct sealing orientation to ensure the normal operation of the subsequent document filling process.

[0121] In one embodiment, different patterns are printed on different positions on the surface of the document cover 10. The orientation recognition sensor 830 can distinguish different colors. The color sequence of the document cover 10 with the correct sealing orientation when it passes the orientation recognition sensor 830 is used as a reference. When the document cover 10 with the incorrect sealing orientation passes the orientation recognition sensor 830, it will be recognized. At this time, the second rotating member 840 rotates 180°, thereby adjusting the document cover 10 to the correct sealing orientation.

[0122] Furthermore, the second rotating component 840 is a rotary cylinder.

[0123] Please see Figure 5In one embodiment, the support platform 260 is provided with a loading position 261 and a docking position 262. The first adsorption member 210, the first moving member 240, the first rotating member 250 and the pressing mechanism are all located at the loading position 261. The document envelope feeding mechanism 800 is used to transport the document envelope 10 located at the storage position 711 to the docking position 262. The opening and closing mechanism 200 also includes a push plate 270, which is movably disposed on the frame 100 and is used to push the document envelope 10 at the docking position 262 to the loading position 261.

[0124] The document sealing feeding mechanism 800 transports the document sealing 10 from the storage position 711 to the docking position 262 of the carrier platform 260. The pusher plate 270 then pushes the document sealing 10 from the docking position 262 to the filling position 261. The first adsorption member 210, the first moving member 240, the first rotating member 250, and the pressing mechanism are all located at the filling position 261 to fill the document into the document sealing 10.

[0125] Furthermore, the support platform 260 is provided with a clearance slot 263, and the push plate 270 passes through the clearance slot 263 and is used to push the document cover 10 on the support platform 260 to reduce space occupation.

[0126] Please see Figure 7 In one embodiment, the support platform 260 has an adsorption through hole 264, and the first adsorption member 210 passes through the adsorption through hole 264.

[0127] The first adsorption element 210 can adsorb the first surface 13 of the cover 11 on the support platform 260 through the adsorption through hole 264. While ensuring the adsorption effect, it can also save space and make the overall structure of the document loading device more compact.

[0128] Please see Figure 7 In one embodiment, the first moving member 240 includes a first cylinder and a first piston rod. The first cylinder is disposed on the frame 100, and the first piston rod is movably disposed on the first cylinder. The second adsorption member 220 is connected to the first piston rod.

[0129] The first cylinder drives the first piston rod to extend and retract, thereby moving the second adsorption component 220 closer to or away from the document seal 10. This method has low implementation cost and good moving effect.

[0130] Please see Figure 7 In one embodiment, the first rotating member 250 includes a rotating rod and a driving part. The rotating rod is drivenly connected to the driving part. The driving part is disposed on the frame 100 and can drive the rotating rod to rotate. The sealing adsorption member 230 is disposed on the side wall of the rotating rod.

[0131] The drive unit drives the rotating rod to rotate, thereby causing the cap adsorption component 230 to flip, thus realizing the opening and closing of the cap 12.

[0132] Furthermore, the rotating rod includes a first rod body and a second rod body. The support platform 260 is provided with a positioning hole. The first rod body is hinged to the drive unit. One end of the second rod body is hinged to the end of the first rod body away from the drive unit, and the second rod body passes through the positioning hole.

[0133] Please see Figure 7 In one embodiment, the second moving member 420 includes a second cylinder and a second piston rod. The second cylinder is disposed on the frame 100, and the second piston rod is movably disposed on the second cylinder. The clamping member 410 is connected to the second piston rod.

[0134] The second cylinder drives the second piston rod to extend and retract, thereby causing the clamping component 410 to clamp or release the document seal 10. This method is low in cost and has a reliable pressure-resistant effect.

[0135] Please see Figure 7 In one embodiment, the opening and closing mechanism 200 further includes a transverse baffle 281 and a longitudinal baffle 282. When the opening and closing mechanism 200 is in its initial state, the transverse baffle 281 falls, the longitudinal baffle 282 rises, and the pusher plate 270 pushes the document seal 10 to the filling position 261. The transverse baffle 281, the longitudinal baffle 282, the pusher plate 270, and the support platform 260 form a limiting frame to ensure that the document seal 10 is in place. After the document seal 10 is in place, the transverse baffle 281 rises to open the document seal 10 through the first suction member 210, the second suction member 220, and the cap suction member 230. After the document enters the document seal 10, the longitudinal baffle 282 retracts to transport the document seal 10 to the next process.

[0136] Furthermore, the opening and closing mechanism 200 also includes a cover member 290, which is movably disposed on the frame 100 and can move closer to or further away from the cover 12.
