Description

Technical Field

[0001] This application relates to the technical field of release paper removal, and in particular to a release paper removal 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 the privacy and security of items, the efficiency of the sealing process of express delivery documents directly affects the overall process rhythm of express sorting, transfer and delivery.

[0003] Currently, the sealing structure of express document envelopes generally adopts a combination of release paper and pressure-sensitive adhesive. That is, the sealing tongue is pre-coated with pressure-sensitive adhesive, and a layer of release paper is covered on the outside of the pressure-sensitive adhesive to protect it. In actual sealing operations, the release paper must first be completely peeled off from the sealing tongue, and then the sealing tongue is pressed to adhere to the storage part to complete the seal. However, this core operation is still mainly done manually, which is inefficient and has high labor costs. Utility Model Content

[0004] Therefore, it is necessary to provide a release paper removal device to address the problems of low efficiency and high labor costs caused by the need for manual removal of release paper in traditional technologies.

[0005] The technical solution is as follows:

[0006] One embodiment provides a release paper removal device, comprising:

[0007] Mounting frame, the mounting frame having a removal station;

[0008] A removal mechanism is provided on the mounting frame and located at the removal station. The removal mechanism is provided with an adhesive surface for bonding the release paper of the package.

[0009] A contacting mechanism, disposed on the mounting frame and located at the removal station, the contacting mechanism having a contacting part, the contacting part being opposite to and spaced apart from the adhesive surface, forming an adhesive gap between the contacting part and the adhesive surface; and

[0010] A conveying mechanism is provided on the mounting frame. The conveying mechanism is used to feed the package into the removal station so that at least a portion of the release paper is located in the bonding gap. The abutment portion can push the package toward the bonding surface so that the bonding surface is bonded to the release paper. The conveying mechanism is also used to remove the package from the removal station.

[0011] The aforementioned release paper removal device, with its conveying mechanism mounted on the mounting frame, feeds the package into the removal station, ensuring that at least a portion of the release paper on the package is within the bonding gap. Subsequently, the abutting part of the abutting mechanism pushes the side of the package away from the release paper, causing both the package and the release paper to move simultaneously toward the bonding surface of the removal mechanism, thereby bonding the release paper to the bonding surface. At this point, the conveying mechanism then moves the package out of the removal station to separate the release paper from the package. Compared with conventional technology, the aforementioned release paper removal device can quickly remove the release paper from the package without manual operation, resulting in high removal efficiency.

[0012] In one embodiment, the abutting mechanism includes an abutting member and a first driving member. The abutting member is disposed on the first driving member and has the abutting portion.

[0016] In one embodiment, the unwinding component includes an unwinding roller, a first limiting disc, and a second limiting disc. The unwinding roller is rotatably mounted on the mounting frame. The surface of the unwinding roller is used to connect the end of the adhesive tape away from the take-up component. The first limiting disc is located on one side of the unwinding roller, and the second limiting disc is located on the other side of the unwinding roller. The diameters of both the first and second limiting discs are larger than the diameter of the unwinding roller; or / and,

[0017] The winding component includes a winding wheel, a third limiting disc, and a fourth limiting disc. The winding wheel is rotatably mounted on the mounting frame. The wheel surface of the winding wheel is used to connect the end of the adhesive tape away from the unwinding component. The third limiting disc is located on one side of the winding wheel, and the fourth limiting disc is located on the other side of the winding wheel. The diameters of both the third and fourth limiting discs are larger than the diameter of the winding wheel.

[0021] In one embodiment, the package includes a sealing tongue and a receiving portion, the sealing tongue being flexibly disposed in the receiving portion, and the conveying mechanism including a folding member disposed on the path from which the package is displaced by the removal process. The folding member has a folded surface that forms an angle with the plane containing the receiving portion, and the folded surface is used to abut against and bend the sealing tongue so that the sealing tongue is bent relative to the receiving portion.

[0022] In one embodiment, the conveying mechanism includes a limiting member located at the removal station, the limiting member abutting against the side of the package facing the adhesive surface to restrict the package from moving toward the removal mechanism. Attached Figure Description

[0033] 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.

[0034] 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.

[0035] 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.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] 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.

[0038] 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.

[0039] Please see Figures 1 to 3 One embodiment of this application provides a release paper removal device, including a mounting frame 100, a removal mechanism 200, a contacting mechanism 300, and a conveying mechanism 400. The mounting frame 100 has a removal station 110; the removal mechanism 200 is disposed on the mounting frame 100 and located at the removal station 110, and the removal mechanism 200 has an adhesive surface 211 for bonding the release paper 510 of the package 500; the contacting mechanism 300 is disposed on the mounting frame 100 and located at the removal station 110, and the contacting mechanism 300 has a contacting mechanism 400 for bonding the release paper 510 of the package 500. The abutment and the abutment are opposite to and spaced apart from the adhesive surface 211, forming an adhesive gap 310 between the abutment and the adhesive surface 211; the conveying mechanism 400 is provided on the mounting frame 100, and the conveying mechanism 400 is used to send the package 500 into the removal station 110 so that at least a portion of the release paper 510 is located in the adhesive gap 310. The abutment can push the package 500 toward the adhesive surface 211 so that the adhesive surface 211 is bonded to the release paper 510. The conveying mechanism 400 is also used to remove the package 500 from the removal station 110.

[0040] In the aforementioned release paper removal device, the conveying mechanism 400 of the mounting frame 100 feeds the package 500 into the removal station 110, so that at least a portion of the release paper 510 on the package 500 is located within the bonding gap 310. Subsequently, the abutting part of the abutting mechanism 300 pushes the side of the package 500 away from the release paper 510, causing the package 500 and the release paper 510 to move simultaneously toward the bonding surface 211 of the removal mechanism 200, thereby bonding the release paper 510 onto the bonding surface 211. At this time, the conveying mechanism 400 then moves the package 500 out of the removal station 110 to separate the release paper 510 from the package 500. Compared with conventional technology, the aforementioned release paper removal device can quickly remove the release paper 510 from the package 500 without manual operation, resulting in high removal efficiency.

[0041] As an explanation, the release paper 510 is disposed on one side of the package 500. The abutting part of the abutting mechanism 300 can abut against the side of the package 500 away from the release paper 510, so that the release paper 510 is adhered to the adhesive surface 211 of the removal mechanism 200. Under the action of the adhesive force of the adhesive surface 211, the release paper 510 cannot move relative to the adhesive surface 211. At this time, the package 500 is moved out of the removal station 110 by the conveying mechanism 400, so that the release paper 510 and the package 500 can be separated, thereby achieving the purpose of removing the release paper 510.

[0042] Further, please refer to Figure 1 The mounting frame 100 is also provided with a receiving station 120 and a transfer station 130. The equipment upstream of the release paper removal device transports the package 500 to the receiving station 120. The conveying mechanism 400 is used to transport the package 500 from the receiving station 120 to the removal station 110. After the release paper 510 is removed from the package 500, the conveying mechanism 400 then transports the package 500 from the removal station 110 to the transfer station 130 to transfer the package 500 to the equipment downstream of the release paper removal device.

[0043] Optionally, the conveying mechanism 400 can use a robotic arm to convey the package 500, or a guide rail or other feasible methods to convey the package 500, which will not be elaborated here.

[0044] Optionally, the conveying mechanism 400 can fix the package 500 by means of grippers or suction cups, etc., which will not be described in detail here.

[0045] In one embodiment, the adhesive surface 211 is provided with adhesive for bonding the release paper 510 to fix the release paper 510. When the conveying mechanism 400 moves the package 500 out of the removal station 110, the release paper 510 can be torn off to remove the release paper 510.

[0046] Understandably, in other feasible embodiments, the removal mechanism 200 can move relative to the conveying mechanism 400, such that after the adhesive surface 211 of the removal mechanism 200 adheres to the release paper 510, it can drive the release paper 510 away from the conveying mechanism 400 and away from the package 500, so as to remove the release paper 510.

[0047] Please see Figure 1 , Figure 5 and Figure 6 In one embodiment, the package 500 is a document seal, and the release paper 510 is disposed at the sealing tongue 520 of the document seal. The release paper removal device can remove the release paper 510 at the sealing tongue 520 to facilitate the sealing of the document seal.

[0048] Please see Figure 2 In one embodiment, the abutting mechanism 300 includes an abutting member 320 and a first driving member 330. The abutting member 320 is disposed on the first driving member 330 and has an abutting portion. The first driving member 330 is disposed on the mounting bracket 100. The first driving member 330 is used to drive the abutting member 320 closer to or away from the adhesive surface 211.

[0049] The first driving member 330 can drive the abutment member 320 to move so that the abutment part can approach or move away from the adhesive surface 211. In use, the first driving member 330 drives the abutment member 320 to push the side of the package 500 away from the release paper 510, thereby bonding the release paper 510 to the adhesive surface 211. Subsequently, the first driving member 330 drives the abutment part away from the release paper 510, and the conveying mechanism 400 then moves the package 500 out of the removal station 110 to separate the release paper 510 from the package 500.

[0050] Optionally, the first driving component 330 can be a motor, cylinder, or other component, as long as it can drive the abutment 320 to move; no specific limitation is made here.

[0051] Further, please refer to Figure 2 In one embodiment, during the conveying process of the package 500, the package 500 is parallel to the ground. The first driving member 330 drives the abutment member 320 to move back and forth in a direction perpendicular to the ground to abut against the side of the package 500 away from the release paper 510, thereby achieving the bonding between the release paper 510 and the adhesive surface 211.

[0052] Please see Figure 2 In one embodiment, the first driving member 330 includes a cylinder and a piston rod. The cylinder is disposed on the mounting bracket 100, one end of the piston rod is inserted into the cylinder, and the other end of the piston rod is connected to the abutment member 320. The cylinder can drive the piston rod to perform telescopic movement.

[0053] The cylinder can drive the piston rod to move back and forth along the axis of the piston rod, thereby driving the abutment 320 to move back and forth, thus achieving effective bonding between the release paper 510 and the bonding surface 211.

[0054] Please see Figure 2 In one embodiment, the removal mechanism 200 includes an adhesive tape 210 and a contact roller 220, the contact roller 220 being rotatably mounted on the mounting frame 100, the adhesive tape 210 being at least partially wrapped around the contact roller 220, and the side of the adhesive tape 210 away from the contact roller 220 having an adhesive surface 211.

[0055] After the adhesive surface 211 removes the release paper 510 of one package 500, the adhesive tape 210 can move under the rotation of the contact roller 220 to remove the part of the adhesive surface 211 with the release paper 510 adhered to from the adhesive gap 310, and move the adhesive surface 211 without the release paper 510 adhered to the adhesive gap 310 to remove the release paper 510 of the next package 500; in this way, the release paper 510 of multiple packages 500 can be removed continuously, further improving the removal efficiency of the release paper 510.

[0056] As an explanation, when the contact roller 220 rotates, the portion of the adhesive surface 211 opposite to the abutment portion moves and changes. Thus, when a release paper 510 is adhered to a portion of the adhesive surface 211, the adhesive tape 210 moves, thereby removing the portion of the adhesive surface 211 with the release paper 510 adhered to from the adhesive gap 310, and moving the portion of the adhesive surface 211 with the release paper 510 adhered to to a position opposite to the abutment 320, so as to realize the subsequent release paper 510 removal work.

[0057] Understandably, in some embodiments, the adhesive tape 210 can be wrapped around the outer wall of the contact roller 220. When the contact roller 220 rotates, it can position different positions of the adhesive surface 211 of the adhesive tape 210 opposite to the abutment 320 to achieve continuous removal of the release paper 510. In other embodiments, the contact roller 220 can also only serve to support the adhesive tape 210. When the abutment 320 moves toward the contact roller 220, it can bring the adhesive tape 210 and the release paper 510 into contact between the abutment 320 and the contact roller 220. Under the support of the outer wall of the contact roller 220, the release paper 510 can achieve a more reliable bonding effect with the adhesive tape 210.

[0058] Furthermore, the shape of the abutment portion is adapted to the shape of the outer wall of the contact roller 220 to ensure the bonding reliability between the release paper 510 and the adhesive tape 210.

[0059] Please see Figures 2 to 4 In one embodiment, the removal mechanism 200 further includes an unwinding member 230 and a winding member 240, both of which are rotatably mounted on the mounting frame 100. One end of the adhesive tape 210 is connected to the unwinding member 230, and the other end of the adhesive tape 210 passes around the contact roller 220 and is connected to the winding member 240. The unwinding member 230 is used to unwind the adhesive tape 210, and the winding member 240 is used to wind the adhesive tape 210.

[0060] The unwinding member 230 is used to unwind the adhesive tape 210 that is not bonded with release paper 510. When the adhesive surface 211 of the adhesive tape 210 that passes over the contact roller 220 is bonded with release paper 510, the winding member 240 winds up the portion of the adhesive tape 210 that is bonded with release paper 510, so as to achieve continuous removal of release paper 510 from multiple packages 500.

[0061] Furthermore, the unwinding speed of the unwinding component 230 to the adhesive tape 210 should be the same as the winding speed of the rewinding component 240 to the adhesive tape 210.

[0062] In one embodiment, the adhesive tape 210 is an adhesive tape with one side being the adhesive surface 211 and containing adhesive. The adhesive is used to bond the release paper 510, thereby achieving the removal of the release paper 510.

[0063] Please see Figures 4 to 5 In one embodiment, the unwinding member 230 includes an unwinding wheel, a first limiting disc 231, and a second limiting disc 232. The unwinding wheel is rotatably mounted on the mounting frame 100. The wheel surface of the unwinding wheel is used to connect the end of the adhesive tape 210 away from the winding member 240. The first limiting disc 231 is located on one side of the unwinding wheel, and the second limiting disc 232 is located on the other side of the unwinding wheel. The diameter of the first limiting disc 231 and the diameter of the second limiting disc 232 are both larger than the diameter of the unwinding wheel.

[0064] The first limiting disc 231 and the second limiting disc 232 can limit the adhesive tape 210 wound on the surface of the unwinding wheel to prevent the adhesive tape 210 from detaching from the surface of the unwinding wheel, thereby improving the reliability of the storage of the adhesive tape 210.

[0065] Furthermore, the adhesive tape 210 without release paper 510 is wound around the surface of the unwinding wheel, which can rotate to unwind the adhesive tape 210.

[0066] Please see Figures 4 to 5 As an embodiment that can be implemented simultaneously or separately with the above embodiments, the take-up member 240 includes a take-up wheel, a third limiting disc 241 and a fourth limiting disc 242. The take-up wheel is rotatably mounted on the mounting frame 100. The wheel surface of the take-up wheel is used to connect the end of the adhesive tape 210 away from the unwinding member 230. The third limiting disc 241 is located on one side of the take-up wheel, and the fourth limiting disc 242 is located on the other side of the take-up wheel. The diameters of the third limiting disc 241 and the fourth limiting disc 242 are both larger than the diameter of the take-up wheel.

[0067] Similar to the unwinding reel, it will not be described in detail here.

[0068] Please see Figure 2 and Figure 4In one embodiment, the removal mechanism 200 further includes a tension wheel 250, which is movably disposed on the mounting frame 100, and the adhesive tape 210 is wound around the tension wheel 250.

[0069] The tensioning roller 250 can tension the adhesive tape 210, keeping the adhesive tape 210 in a properly taut state. This not only prevents the adhesive tape 210 from detaching from the contact roller 220, but also ensures that the adhesive surface 211 of the adhesive tape 210 can achieve a more reliable bond with the release paper 510.

[0070] Further, please refer to Figure 2 The removal mechanism 200 also includes a movable part 280, which is disposed on the mounting frame 100. The tension wheel 250 is rotatably disposed on the movable part 280. The movable part 280 can move relative to the mounting frame 100 and drive the tension wheel 250 to move, so as to adjust the tension of the adhesive tape 210.

[0071] In one embodiment, at least two tensioning rollers 250 are provided to further improve the tensioning effect on the adhesive tape 210.

[0072] Please see Figure 4 and Figure 5 As an embodiment that can be implemented simultaneously or separately with the above embodiments, the removal mechanism 200 further includes a second driving member 260. The second driving member 260 is disposed on the mounting frame 100 and drivenly connected to the winding member 240. The second driving member 260 is used to drive the winding member 240 to rotate.

[0073] The second driving member 260 can drive the winding member 240 to rotate in order to wind up the adhesive tape 210 to which the release paper 510 is attached, thereby realizing the continuous removal of the release paper 510 from multiple packages 500.

[0074] Furthermore, the second driving member 260 includes a drive motor, the output shaft of which is connected to the winding member 240 to drive the winding member 240 to rotate.

[0075] Please see Figure 2 In one embodiment, the removal mechanism 200 further includes a first sensor 270, which is disposed on the mounting frame 100 and located on the path of the package 500 moving out of the removal station 110. The first sensor 270 is electrically connected to the second drive member 260. When the first sensor 270 senses that the package 500 has moved out of the removal station 110, the second drive member 260 drives the winding member 240 to rotate in order to wind up the adhesive tape 210 to which the release paper 510 is bonded.

[0076] Furthermore, in some embodiments, the second drive member 260 drives the winding member 240 to wind the adhesive tape 210, and the conveying mechanism 400 drives the package 500 after the release paper 510 is torn away from the removal station 110, which can be carried out simultaneously, thereby further improving the removal efficiency of the release paper 510.

[0077] Understandably, in other embodiments, the removal mechanism 200 further includes a third drive member (not shown in the figure), which is disposed on the mounting frame 100 and drivenly connected to the unwinding member 230. The third drive member is used to drive the unwinding member 230 to rotate.

[0078] Please see Figure 3 In one embodiment, the conveying mechanism 400 includes a conveying guide rail 410, a moving member 420, and a picking member 430. The conveying guide rail 410 is disposed on the mounting frame 100, the moving member 420 is movably disposed on the conveying guide rail 410 so that the moving member 420 can move into or out of the removal station 110, and the picking member 430 is disposed on the moving member 420 and is used to pick up or release the package 500.

[0079] After the pickup component 430 picks up the package 500, the moving component 420 can move relative to the conveying guide rail 410 to drive the pickup component 430 into or out of the removal station 110 of the mounting frame 100, thereby driving the package 500 to move, thus realizing the removal of the release paper 510.

[0080] Further, please refer to Figure 1 and Figure 3 The mounting frame 100 is provided with a receiving station 120, a removal station 110 and a transfer station 130 in sequence along the extension direction of the conveying guide rail 410. The picking component 430 first picks up the package 500 with the release paper 510 still attached at the receiving station 120. The moving component 420 drives the picking component 430 to move to the removal station 110 under the guidance of the conveying guide rail 410 to remove the release paper 510 on the package 500. After the release paper 510 is removed, the package 500 moves to the transfer station 130 under the drive of the moving component 420. At this time, the picking component 430 releases the package 500 to transfer the package 500 to the downstream equipment.

[0081] Furthermore, the conveying mechanism 400 also includes a fourth driving member, which is drivenly connected to the moving member 420 and is used to drive the moving member 420 to reciprocate along the extension direction of the conveying guide rail 410, so as to drive the picking member 430 to move.

[0082] Optionally, the fourth driving component can be a drive motor or a ball screw module, as long as it can achieve the driving effect on the moving component 420, which will not be elaborated here.

[0083] Optionally, the pickup component 430 can be a gripper, a suction cup, or other similar device, as long as it can pick up the package 500. Further details will not be provided here.

[0084] Please see Figure 3 In one embodiment, the pickup 430 includes a telescopic gripper with a first gripper body 431 and a second gripper body 432, which can move closer to or further away from each other to grip or release the package 500.

[0085] Furthermore, the telescopic gripper extends to grip the package 500, and retracts to release the package 500. When the telescopic gripper retracts, the bottom surface of the second gripper is higher than the plane where the package 500 is located, so as to make room to transfer the package 500 from the transfer station 130 to the downstream equipment.

[0086] Please see Figure 3 and Figure 6 In one embodiment, the package 500 includes a sealing tongue 520 and a receiving portion 530. The sealing tongue 520 is foldably disposed in the receiving portion 530. The conveying mechanism 400 includes a folding member 440, which is disposed on the path on which the package 500 moves out of the removal station 110. The folding member 440 has a folded surface 441, which forms an angle with the plane where the receiving portion 530 is located. The folded surface 441 is used to abut against and bend the sealing tongue 520 so that the sealing tongue 520 is bent relative to the receiving portion 530.

[0087] To facilitate the removal of the release paper 510 on the sealing tongue 520, before and after removing the release paper 510, the sealing tongue 520 and the storage part 530 are roughly on the same plane. In order to facilitate the sealing tongue 520 to adhere to the storage part 530 after the release paper 510 is removed, so as to achieve the sealing of the storage part 530, after removing the release paper 510, the folded edge surface 441 of the folding edge member 440 is used to abut against the sealing tongue 520, so that the sealing tongue 520 can be bent, so that the sealing tongue 520 can be fastened and adhered to the storage part 530 in subsequent operations to achieve the sealing of the storage part 530.

[0088] Further, please refer to Figure 6 The folded surface 441 of the folded part 440 has a first side 4411 and a second side 4412. The height of the first side 4411 is less than the height of the plane where the storage part 530 is located, and the height of the second side 4412 is greater than the height of the plane where the storage part 530 is located. The first side 4411 is located close to the removal station 110, and the second side 4412 is located away from the removal station 110.

[0089] Thus, the sealing tongue 520 will first contact the first side 4411. Since the height of the first side 4411 is less than the height of the plane where the storage part 530 is located, and the height of the second side 4412 is greater than the height of the plane where the storage part 530 is located, when the sealing tongue 520 moves from the first side 4411 to the second side 4412, the folded edge 441 will gradually raise the position of the sealing tongue 520 so that the sealing tongue 520 can gradually bend, thereby adjusting the sealing tongue 520 from a horizontal state to an upright slightly inward-curving state, which makes it convenient to fasten and glue the sealing tongue 520 to the storage part 530 later.

[0090] Please see Figure 3 and Figure 4 In one embodiment, the release paper removal device further includes a conveyor belt mechanism 600, which is disposed on the mounting frame 100 and located at the transfer station 130. The conveyor belt mechanism 600 is used to transfer the package 500 after the release paper 510 has been removed to the downstream equipment for the next process.

[0091] Furthermore, the release paper removal device also includes a second sensor 700, which is located on the conveyor belt mechanism 600 and is used to monitor whether the telescopic gripper retracts. When the second sensor 700 detects that the telescopic gripper has retracted, it sends a signal to the conveyor belt mechanism 600. After receiving the signal, the conveyor belt mechanism 600 will run for several seconds to transfer the package 500 after the release paper 510 has been removed to the downstream equipment.

[0092] Please see Figure 3 and Figure 4 In one embodiment, the conveying mechanism 400 includes a limiting member 450 located at the removal station 110. The limiting member 450 is used to abut against the side of the package 500 facing the adhesive surface 211 to restrict the movement of the package 500 toward the removal mechanism 200.

[0093] The limiting member 450 can restrict the package 500 from moving toward the removal mechanism 200. In this way, it can prevent the release paper 510 from pulling on the package 500 when it is torn off, which would cause deformation of the package 500 or cause it to fall off the conveying mechanism 400.

[0094] Further, please refer to Figure 3 and Figure 4 The limiting member 450 includes a connecting part 451, a transition part 452, and a limiting part 453. One end of the connecting part 451 is disposed on the mounting bracket 100, and the other end of the connecting part 451 is connected to one end of the transition part 452. The end of the transition part 452 away from the connecting part 451 is connected to the limiting part 453. The end of the limiting part 453 away from the transition part 452 is provided toward the receiving part 530 of the encapsulation 500 to restrict the movement of the receiving part 530 toward the removal mechanism 200.

[0095] Furthermore, please refer to Figure 4 The transition section 452 is provided with a clearance groove 454, which is used to avoid the sealing tongue 520.

[0096] This design allows for the limitation of the storage section 530 while also avoiding the sealing tongue 520 perpendicular to the storage section 530, making the overall structure of the release paper removal device more compact.

[0097] Please see Figure 3 and Figure 4 In one embodiment, at least two limiting members 450 are provided, and the at least two limiting members 450 are spaced apart along the path on which the package 500 moves out of the removal station 110, thereby further preventing the package 500 from deforming or detaching from the conveying mechanism 400.

[0098] Please see Figure 5 and Figure 7 In one embodiment, the release paper removal device further includes a first limiting component 810, a second limiting component 820, and a lifting component 830. The lifting component 830 is used to support the package 500. Since the angle between the sealing tongue 520 and the receiving part 530 is unstable, the sealing tongue 520 can be flattened by the first limiting component 810 in order to make the position of the package 500 at the removal station 110 relatively accurate. The second limiting component 820 can prevent the horizontal posture of the document seal from changing when the adhesive tape 210 pulls on the package 500, thereby limiting the activity space of the package 500.

[0099] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0100] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
