Description

Technical Field

[0001] This application relates to the field of paper packaging printing technology, and in particular to a flipping mechanism and a receiving device. Background Technology

[0002] Paper packaging products are widely used in all aspects of daily life, including clothing, food, housing, and transportation. Among paper packaging containers, there is an important category—color box packaging. The production process of color box packaging involves printing color on cardboard, then laminating it with corrugated paper or cardboard and other materials that can be used to reinforce paper packaging containers. After die-cutting and gluing, the color box is made by laminating paper to produce color boxes. The beautiful appearance of the color-printed cardboard is the primary factor in the reputation of the packaging box and the product inside. Therefore, the entire production process must ensure that the surface of the color-printed cardboard is not scratched or damaged.

[0003] In this process, color-printed cardstock and corrugated paper are bonded together using adhesive. After drying, the color-printed cardstock, being a denser material, evaporates moisture more slowly, while the base paper, being less dense, evaporates moisture more quickly. Therefore, the bonded papers warp and buckle due to their different shrinkage and deformation during drying.

[0004] The bending and warping of the laminated paper is detrimental to or prevents subsequent die-cutting and box-making processes. Therefore, the laminating process involves human intervention during material receiving to prevent deformation. Currently, the laminated paper is usually stacked to a certain thickness and placed on a pallet in an orderly manner with the front and back facing each other, so that the deformation can be offset by pressing the laminated paper against each other.

[0005] Therefore, the production process of color box packaging also requires flipping the laminated paper. Currently, the mechanism used for flipping the laminated paper supports the printed cardboard surface of the laminated paper during the flipping process. Then, a paper pushing mechanism pushes the laminated paper, which comes into contact with the printed cardboard through friction with the support surface, outwards. This causes scratches and damage to the printed cardboard surface of the laminated paper, resulting in a low production yield. Alternatively, manual flipping is used, but this method is time-consuming and labor-intensive, and also has low flipping efficiency, which is detrimental to improving the production efficiency of color box packaging. Summary of the Invention

[0006] Therefore, it is necessary to provide a flipping mechanism and a receiving device to address the problems of low production efficiency of existing paper-folding mechanisms and low efficiency of manual flipping.

[0007] A flipping mechanism, comprising:

[0008] A conveying structure is used to convey laminated paper along a first direction. The laminated paper passes through a flipping position and a pre-folding position during the conveying process. The laminated paper has a laminating bottom paper surface and a color-printed cardboard surface that are opposite each other along the gravity direction. The gravity direction intersects with the first direction. When it is in the flipping position, the laminating bottom paper surface of the laminated paper faces the conveying structure.

[0009] The flipping structure is rotatable relative to the conveying structure about a flipping axis, the direction of which intersects both the first direction and the direction of gravity;

[0010] The flipping structure is used to support the bonding bottom paper surface of the bonding paper located at the flipping position, and to drive the bonding paper to flip until the color-printed cardboard surface of the bonding paper is facing upwards from the pre-stacked position in the direction of gravity and then released.

[0011] In one embodiment, the flipping structure has sequentially passing lifting positions and releasing positions, and has a lifting surface for lifting the adhered paper;

[0012] When the flipping structure is in the lifting position, the lifting surface is parallel to the first direction (X) and in contact with the bonding bottom paper surface. When the flipping structure is in the release position, the lifting surface is parallel to the first direction and faces upwards from the pre-stacked position.

[0013] In one embodiment, the flipping structure has an avoidance position during rotation, and when the flipping structure is in the avoidance position, the flipping structure avoids the conveying path of the paper being bonded.

[0014] In one embodiment, the conveying structure has a conveying surface for conveying the bonded paper along the first direction, and the flipping axis is higher than the conveying surface in the direction of gravity;

[0015] When the flipping structure is in the avoidance position, the flipping structure is higher than the conveying surface, and the height difference between the flipping structure and the conveying surface is greater than the thickness of the bonding paper in the direction of gravity.

[0016] In one embodiment, the flipping structure includes a lifting body and a rotating body. The lifting body is provided with the lifting surface, and the rotating body is installed at an angle on the lifting body. One end of the rotating body away from the lifting body is rotatably installed on the conveying structure around the flipping axis.

[0017] When the flipping structure is in the lifting position, the lifting body extends into the cardboard located in the flipping position below it in the direction of gravity.

[0018] In one embodiment, the conveying structure is provided with a lifting groove, the opening of which faces the flipping position. When the flipping structure is in the lifting position, the lifting body extends into the lifting groove.

[0019] In one embodiment, the conveying structure has two sets of conveying rollers spaced apart along the direction of the flipping axis, and the lifting groove is formed between the two sets of conveying rollers. Each set of conveying rollers includes a plurality of conveying rollers spaced apart along the first conveying direction, and the axis of each conveying roller is parallel to the direction of the flipping axis.

[0020] In one embodiment, the conveying structure further includes a paper pusher disposed on one end of at least one set of conveying rollers in the first direction away from the pre-stacked position.

[0021] In one embodiment, the flipping structure further includes a locking component, which locks the adhesive paper when the flipping structure is in the lifting position, and releases the adhesive paper when the flipping structure is in the releasing position.

[0022] In one embodiment, the flipping structure includes a lifting body and a rotating body, the rotating body being mounted at an angle on the lifting body, and the end of the rotating body facing away from the lifting body being rotatably mounted on the conveying structure around the flipping axis;

[0023] The locking assembly includes a first locking member and a second locking member. The first locking member is installed on the lifting body, and the second locking member is installed on the rotating body. When the flipping structure is in the lifting position, the first locking member and the rotating body are spaced apart along the first direction, and the adhesive paper is located between the first locking member and the rotating body.

[0024] The first locking member has a first locking portion that can move relative to itself, and the second locking member has a second locking portion that can move relative to itself. When the locking assembly locks the bonding paper, both the first locking portion and the second locking portion are located on one side of the color-printed cardboard surface of the bonding paper. When the locking assembly releases the bonding paper, both the first locking portion and the second locking portion avoid the color-printed cardboard surface of the bonding paper located on the flip structure.

[0025] In one embodiment, the first locking member includes a support portion mounted on the lifting body, and one end of the first locking portion is movably mounted on the support portion around a locking axis. When the flipping structure is in the lifting position, the locking axis is parallel to the direction of gravity, and the longitudinal direction of the first locking portion intersects the direction of gravity.

[0026] In one embodiment, the support portion can be controlled to move closer to or further away from the rotating body.

[0027] In one embodiment, the flipping structure further includes a flipping screw that can rotate about its own axis, and the support portion has a flipping threaded hole, and the flipping screw is threadedly connected to the flipping threaded hole;

[0028] The lifting body has a guide hole, and the support part passes through the guide hole. When the flipping structure is in the lifting position, the flipping screw and the guide hole are both longitudinally extended along the first direction.

[0029] In one embodiment, the second locking member includes a mounting portion mounted on the rotating body. When the flipping structure is in the lifting position, the second locking portion is retractably mounted on the mounting portion along the first direction.

[0030] A material receiving device includes a flipping mechanism as described in any of the preceding claims.

[0031] In one embodiment, the receiving device further includes a stacking mechanism and a stacking pallet, the stacking mechanism being used to transport the laminated paper located at the pre-stacked position onto the stacking pallet.

[0032] In one embodiment, the stacking mechanism includes a body and a robotic arm, the body being used to drive the robotic arm to move in three-dimensional space, the robotic arm being able to grasp and release the paper being bonded.

[0033] In one embodiment, the robotic arm includes a frame and two opening / closing members. The frame is connected to the body to move in three-dimensional space. The two opening / closing members are spaced apart from the frame along the rotation axis and can be controlled to move closer to or further away from each other.

[0034] The robotic arm also includes multiple hooks. Each of the opening and closing components is provided with multiple hooks at intervals along a first direction. Each hook extends longitudinally along the direction of gravity at one end away from the opening and closing component and is provided with a hook portion facing another opening and closing component.

[0035] In one embodiment, the robotic arm further includes an opening and closing screw disposed on the frame. The opening and closing screw is longitudinally elongated along the rotation axis and rotatable about its own axis. One end of the opening and closing screw is provided with a first threaded section, and the other end is provided with a second threaded section. The first threaded section and the second threaded section have opposite directions of rotation.

[0036] Each of the opening and closing components is provided with an opening and closing threaded hole, one of the opening and closing threaded holes is threadedly connected to the first threaded segment, and the other opening and closing threaded hole is threadedly connected to another second threaded segment;

[0037] The frame also includes a guide rod that extends longitudinally along the rotation axis, and the guide rod is slidably connected to the two opening and closing members.

[0038] In one embodiment, the robotic arm body is provided with a paper suction device.

[0039] In the aforementioned flipping mechanism, during the flipping process, the flipping structure lifts the laminated paper at the flipping position, allowing it to move along with the structure. When the laminated paper's backing surface faces the pre-stacked position above the gravitational direction Y, the laminated paper has already been flipped along with the flipping structure. The flipped stack of laminated paper then faces the existing stack of unflipped laminated paper at the pre-stacked position, ensuring the two stacks overlap and prevent scratches or damage to the printed cardboard surface, forming a new stack. The stacking mechanism then picks them up and stacks them on the pallet without scratching or damaging the laminated paper's backing surface, thus preventing increased product scrap rates. This method also improves production efficiency compared to traditional manual flipping of laminated paper. In summary, the aforementioned flipping mechanism and receiving equipment can protect the backing paper and printed cardboard from scratches and damage, improving the production qualification rate. Furthermore, it allows multiple stacks of laminated paper to be stored on a single pallet, saving pallets and reducing production space requirements. This, in turn, helps improve the production efficiency of color box packaging. Attached Figure Description

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.

[0063] 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.

[0064] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0067] See Figure 1 and Figure 2 This application provides a receiving device. The discharging device 30 feeds the laminated paper 20 into the receiving device for stacking. The receiving device includes a conveying structure 100 and a flipping mechanism 10. The laminated paper 20 is fed into the flipping mechanism 10 through the discharging device 30. The flipping mechanism 10 includes a conveying structure 100 and a flipping structure 200. The conveying structure 100 is used to convey the laminated paper 20 along a first direction X. The discharging device 30 is set at the starting end of the conveying structure 100. The laminated paper 20 output by the discharging mechanism directly enters the conveying structure 100 and continues to be conveyed along the first direction X through the conveying structure 100.

[0068] The bonding paper 20 has a bonding bottom paper surface 21 and a color-printed cardboard surface 22. When the bonding paper 20 is in the flip position 110, the bonding bottom paper surface 21 of the bonding paper 20 faces the conveying mechanism 100, and the gravity direction Y intersects with the first direction X. That is, the conveying structure 100 conveys the bonding paper 20 in the horizontal direction. The color-printed cardboard surface 22 and the bonding bottom paper surface 21 of the bonding paper 20 in the flip position 110 are the top and bottom of the bonding paper 20, respectively, and the bottom of the bonding paper 20 in the flip position 110 is located on the conveying mechanism 100.

[0069] The flipping structure 200 is rotatable relative to the conveying structure 100 around a flipping axis. The flipping axis direction Z intersects both the first direction X and the gravity direction Y, and is located between the flipping position 110 and the pre-stack position 120. The flipping structure 200 is used to lift the bonding bottom paper surface 21 of the bonding paper 20 located at the flipping position 110 and drive the bonding paper 20 to flip. When the bonding bottom paper surface 21 of the bonding paper 20 faces upward towards the pre-stack position 120 in the gravity direction and is released.

[0070] Thus, during the flipping process, the flipping structure 200 can lift the adhesive paper 20 located at the flipping position 110 so that it can move together with the flipping structure 200. When the color-printed cardboard surface 22 of the adhesive paper 20 on the flipping structure 200 is facing the pre-stacked position 120 above the direction of gravity Y, the adhesive paper 20 has already been flipped together with the flipping structure 200. Afterwards, the adhesive paper 20 returns to the pre-stacked position 120 under the action of gravity.

[0071] In some embodiments of this application, the flipping structure 200 has sequentially passed lifting and releasing positions, and has a lifting surface 201 for lifting the adhered paper 20. When the flipping structure 200 is in the lifting position, such as Figure 3 As shown, the lifting surface 201 is parallel to the first direction X and contacts the bonding bottom paper surface 21 of the bonding paper 20, thereby lifting the bonding paper 20 through the lifting surface 201 and moving the bonding paper 20 to the release position. When the flipping structure 200 is in the release position, as... Figure 5 As shown, the lifting surface 201 is parallel to the first direction X and faces the top of the pre-folding position 120. That is, the lifting surface 201 rotates 180°, and then lifts the adhesive paper 20 to rotate 180° together to complete the flipping. At this time, after the flipping structure 200 releases the adhesive paper 20, the adhesive paper 20 will fall into the pre-folding position 120 under the action of gravity.

[0072] In some embodiments of this application, the bonded paper 20 needs to be stacked in an orderly manner, that is, the unflipped bonded paper 20 is stacked on top of the flipped bonded paper 20. For this purpose, the flipping structure 200 also includes an avoidance position during the movement. When the flipping structure 200 is in the avoidance position, the flipping structure 200 avoids the conveying path of the bonded paper 20, that is, the bonded paper 20 can be normally transported to the pre-stacked position 120 through the flipping position 110.

[0073] Specifically, when the bonded paper sheets 20 need to be stacked in an orderly, reverse-oriented manner, the conveying structure 100 can control the flipping structure 200 to move to an avoidance position when conveying the first stack of bonded paper sheets 20, so that the first stack of bonded paper sheets 20 is conveyed directly to the pre-stacking position 120 without passing through the flipping structure 200. When conveying the second stack of bonded paper sheets 20, the conveying structure 100 can first control the flipping structure 200 to move to a lifting position to lift the bonded paper sheets 20, and then control the flipping structure 200 to move to a release position. At this time, since the first stack of bonded paper sheets 20 has already been placed on the pre-stacking position 120, the second stack of bonded paper sheets 20 on the flipping structure 200 will fall on top of the first stack of bonded paper sheets 20 under the action of gravity, completing the stacking of the bonded paper sheets 20 and forming a new stack of paper sheets. Furthermore, since the first stack of laminated paper 20 is not flipped, while the second stack of laminated paper 20 is flipped 180 degrees by the flipping structure 200, the first and second stacks of laminated paper 20 forming the new paper stack can be stacked with the printed cardboard on their respective lamination surfaces facing each other. This ensures that the printed cardboard on the laminated paper in the new paper stack is centered, preventing the stacking mechanism from scratching or damaging the printed cardboard surface when picking up the new paper and placing it on the stacking plate, thus avoiding a decrease in production yield. This also improves production efficiency.

[0074] In some embodiments, the conveying structure 100 has a conveying surface 130 for conveying the bonding paper 20 along a first direction X, and a flipping axis is higher than the conveying surface 130 in the gravitational direction Y, so that the flipping structure 200 can rotate above the conveying surface 130, thereby providing space for the bonding paper 20 to pass through.

[0075] Specifically, when the flipping structure 200 is in the flipped position 110, the flipping structure 200 is higher than the conveying surface 130, and the height of the flipping structure 200 and the conveying surface 130 is greater than the thickness of the paper 20 in the gravitational direction Y, such as... Figure 3 As shown, the space between the flipping structure 200 and the conveying surface 130 can accommodate the passing of the bonding paper 20, so that the bonding paper 20 can enter the pre-folding position 120 from the flipping position 110.

[0076] In some specific embodiments, since the flipping axis of the flipping structure 200 is higher than the conveying surface 130, but the flipping structure 200 needs to rotate to the bonding bottom paper surface 21 of the bonding paper 20 to support the bonding paper 20, the flipping structure 200 includes a supporting body 210 and a rotating body 220. The rotating body 220 is mounted at an angle on the supporting body 210, and the end of the rotating body 220 away from the supporting body 210 is rotatably mounted on the conveying structure 100 around the flipping axis.

[0077] When the flipping structure 200 is in the lifting position, the lifting body 210 extends below the adhesive paper 20 located in the flipping position 110 in the gravitational direction Y, such as Figure 3 As shown, when the rotating body 220 drives the lifting body 210 to rotate clockwise, the rotating body 220 will lift the paper 20 and cause the flipping structure 200 to move into the avoidance position, as... Figure 4 As shown, at this point, depending on whether the bonding paper 20 is placed on the pre-folding position 120, it can be selected whether to continue transporting the bonding paper 20 to the pre-folding position 120. Finally, rotating the main body 220 drives the lifting main body 210 to continue moving, and the flipping structure 200 will enter the release position, as shown. Figure 5 As shown, at this time, the bonding paper 20 falls onto the existing unflipped bonding paper 20 on the pre-stack position 120 under the action of gravity, forming an orderly stacked state.

[0078] In some embodiments, in order to enable the lifting body 210 to extend under the adhesive paper 20, the conveying structure 100 is provided with a lifting groove 131. The opening of the lifting groove 131 faces the flipping position 110. When the flipping structure 200 is in the lifting position, the lifting body 210 extends into the lifting groove 131, so that the lifting body 210 can be located under the adhesive paper 20 to lift the adhesive paper 20.

[0079] In some specific embodiments, in order to form a lifting groove 131 on the conveying structure 100 without affecting the conveying structure 100's transport of the bonded paper 20, the conveying structure 100 has two sets of conveying rollers 140 arranged at intervals parallel to the axis of rotation. A lifting groove 131 is formed between the two sets of conveying rollers 140. Each set of conveying rollers 140 includes multiple conveying rollers 140 arranged at intervals along the first direction X. All conveying rollers 140 form a conveying surface 130 for conveying the bonded paper 20. The axis of each conveying roller 140 is parallel to the direction Z of the flipping axis.

[0080] Thus, a lifting groove 131 is formed between the two sets of conveyor rollers 140, allowing the lifting body 210 to extend under the bonding paper 20 through the lifting groove 131. Other parts of the bonding paper 20 are normally supported by the two sets of conveyor rollers 140. When the flipping structure 200 is in the flipped position 110, the bonding paper 20 can also be normally conveyed by the two sets of conveyor rollers 140. It should be noted that...

[0081] In some specific embodiments, the conveying structure 100 further includes a paper pusher 150, which is disposed on at least one set of conveying rollers 140 at the end away from the pre-stack position 120 in the first direction X. The paper pusher 150 pushes the bonding paper 20 fed onto the conveying structure 100, allowing the bonding paper 20 to move on the conveying rollers 140. Depending on the pushing distance of the pusher, the bonding paper 20 can be controlled to remain at the flip position 110 or the pre-stack position 120.

[0082] In some embodiments of this application, see [reference] Figure 6 When the flipping structure 200 rotates the adhesive paper 20, the adhesive paper 20 may fall off the flipping structure 200 prematurely during its movement, causing the position of the adhesive paper 20 to change. To address this, the flipping structure 200 also includes a locking component 230. When the flipping structure 200 is in the lifting position, the locking component 230 locks the adhesive paper 20, ensuring that the adhesive paper 20 is fixed to the flipping structure 200 and preventing it from falling off during the rotation of the flipping structure 200 to the release position. When the flipping structure 200 rotates to the release position, the locking component 230 releases the adhesive paper 20, allowing the adhesive paper 20 to separate from the flipping structure 200 and fall onto the unflipped adhesive paper 20 on the pre-stack position 120 under the action of gravity. This completes the stacking of the two stacks of adhesive paper 20 with the color-printed card facing each other, ensuring that the color-printed card of the adhesive paper is in the center direction of the newly stacked paper stack. The stacking mechanism will not scratch the color-printed card when picking up and stacking, and will not reduce the product qualification rate.

[0083] In some embodiments, the flipping structure 200, in order to lift the paper to be bonded 20, includes a lifting body 210 and a rotating body 220. The rotating body 220 is mounted at an angle on the lifting body 210, and one end of the rotating body 220 facing away from the lifting body 210 is rotatably mounted on the conveying structure 100 about the flipping axis. To lock and release the paper to be bonded 20 using the locking assembly 230, the locking assembly 230 includes a first locking member 240 and a second locking member 250. The first locking member 240 is mounted on the lifting body 210, and the second locking member 250 is mounted on the rotating body 220. When the flipping structure 200 is in the lifting position, the first locking member 240 and the rotating body 220 are spaced apart along a first direction X, and the paper to be bonded 20 is located between the first locking member 240 and the rotating body 220.

[0084] The first locking member 240 has a first locking part 241 that can move relative to itself, and the second locking member 250 has a second locking part 251 that can move relative to itself. When the locking assembly 230 locks the bonding paper 20, the first locking part 241 and the second locking part 251 are both located on one side of the color-printed cardboard surface 22 of the bonding paper 20. Since the bonding bottom paper surface 21 of the bonding paper 20 is supported by the lifting body 210, the color-printed cardboard surface 22 of the bonding paper 20 is limited by the first locking part 241 and the second locking part 251. The bonding paper 20 is limited on both sides of the first direction X by two limiting members. Therefore, during the rotation of the flipping structure 200, the bonding paper 20 is restricted by the first locking member 240, the second locking member 250 and the lifting body 210, and will not fall off the flipping structure 200 until the flipping structure 200 moves to the release position.

[0085] When the flipping structure 200 is in the release position and the release component releases the adhesive paper 20, the first locking part 241 and the second locking part 251 are both located away from the color-printed cardboard surface 22 of the adhesive paper 20. That is, the color-printed cardboard surface 22 of the adhesive paper 20 is no longer limited by the two first locking parts 241 and the second locking parts 251. Under the action of gravity, the adhesive paper 20 will fall away from the flipping structure 200 and finally fall onto the unflipped adhesive paper 20 on the pre-stacked position 120, completing the stacking of the adhesive paper 20.

[0086] In some specific embodiments, the first locking member 240 includes a support portion 242 mounted on the lifting body 210, and one end of the first locking portion 241 is movably mounted on the support portion 242 around a locking axis. When the flipping structure 200 is in the lifting position, the locking axis is parallel to the gravity direction Y, and the longitudinal direction of the first locking portion 241 intersects the gravity direction Y.

[0087] Thus, when the flipping structure 200 is in the supporting position, the first locking part 241 can be controlled to rotate, so that the free end of the first locking part 241 is located on the color-printed cardboard surface 22 of the paper 20, thereby locking the color-printed cardboard surface 22 of the paper 20 and preventing the paper 20 from leaving the flipping structure 200. When the flipping structure 200 is in the released position, the first locking part 241 can be controlled to rotate, so that the free end of the first locking part 241 avoids the color-printed cardboard surface 22 of the paper 20. For example, if it is rotated until the support part 242 is away from the color-printed cardboard surface 22 of the paper 20, the restriction on the paper 20 is released.

[0088] Furthermore, the support 242 can be controlled to move closer to or further away from the rotating body 220, and by controlling the distance between the support 242 and the support of the rotating body 220, the paper 20 can be pressed tightly to prevent relative movement between the paper 20 and the flipping structure 200 during the rotation of the paper 20, which would otherwise cause scratches on the paper 20.

[0089] Specifically, the flipping structure 200 also includes a flipping screw 243 rotatable around its own axis. A flipping threaded hole 244 is provided on the support part 242, and the flipping screw 243 is threadedly connected to the flipping threaded hole 244. A guide hole 245 is provided on the supporting body 210, and the support member passes through the guide hole 245. When the flipping structure 200 is in the supporting position, both the flipping screw 243 and the guide hole 245 extend along the first direction X. Thus, when the flipping screw 243 rotates, the rotation of the flipping screw 243 is converted into the movement of the support part 242 along the flipping screw 243 through the flipping threaded hole 244, and the guide hole 245 limits the support part 242, preventing it from rotating and allowing it to move only along the flipping screw 243. Finally, by controlling the forward or reverse rotation of the flipping screw 243, the support part 242 is controlled to move closer to or further away from the rotating body 220. The flipping structure 200 also includes a snap-fit ​​moving motor 260, which is mounted on the lifting body 210 and is used to drive the flipping screw 243 to rotate forward or backward.

[0090] In some embodiments, the second locking member 250 includes a mounting portion 252 mounted on the rotating body 220. When the flipping structure 200 is in the lifting position, the second locking portion 251 is telescopically mounted on the mounting portion 252 along the first direction X. Thus, when the second locking portion 251 extends, it can limit the color-printed cardboard surface 22 of the paper 20 to cooperate with the first locking member 240 to lock the paper 20. When the second locking portion 251 retracts, it can avoid the color-printed cardboard surface 22 of the paper 20, allowing the paper 20 to leave the flipping structure 200 normally.

[0091] This application also provides a receiving device, which includes a flipping mechanism 10 as described in any of the above embodiments. Through the flipping mechanism 10, the automatic flipping of the pasted paper 20 can be realized, thereby improving the production efficiency of color box packaging.

[0092] In some embodiments of this application, see [reference] Figure 7 and Figure 8After the laminated paper 20 is stacked in an orderly manner at the pre-stack position 120, it is necessary to remove the stacked laminated paper 20 from the pre-stack position 120 to facilitate a new round of stacking of laminated paper 20. For this purpose, the receiving equipment also includes a stacking mechanism 300 and a stacking pallet 400. The stacking mechanism 300 is used to transport the laminated paper 20 located at the pre-stack position 120 to the stacking pallet 400.

[0093] Specifically, whenever two stacks of laminated paper 20 are stacked face down at the pre-stack position 120, the stacking mechanism 300 transfers the two stacked stacks of laminated paper 20 together to the stacking laminated paper 20. Then, when a new round of two stacks of laminated paper 20 are stacked face down at the pre-stack position 120, the stacking mechanism 300 transfers the new round of stacked laminated paper 20 to the stacking laminated paper 20 and stacks it on top of the previous laminated paper 20. This allows multiple layers of laminated paper 20 to be stacked on the stacking plate for easy transport.

[0094] In some embodiments, see Figure 8 and Figure 9 The stacking mechanism 300 includes a body 310 and a robot arm 320. The body 310 is used to drive the robot arm 320 to move in three-dimensional space. The robot arm 320 can grasp and release the laminated paper 20 located on the pre-stack position 120, transfer the laminated paper 20 to the stacked laminated paper 20 and then release the laminated paper 20, thus completing the transfer and stacking of the laminated paper 20.

[0095] In some specific embodiments, the robotic arm 320 includes a frame 321 and two opening and closing members 322. The frame 321 is connected to the body 310 to move in three-dimensional space. The two opening and closing members 322 are arranged at intervals along the rotation axis direction with the frame 321 and can be controlled to move closer or further away from each other. Each opening and closing member 322 has a hook at one end away from the frame 321, and the hook of each opening and closing member 322 extends longitudinally toward the other opening and closing member 322.

[0096] The robotic arm 320 also includes multiple hooks 323. Multiple hooks 323 are spaced apart along the first direction X on each opening and closing member 322. Each hook 323 extends longitudinally along the gravity direction Y at one end away from the opening and closing member 322 and is provided with a hook portion 324 facing another opening and closing member 322.

[0097] Thus, when the robotic arm 320 moves to the pre-stack position 120, and the adhesive paper 20 on the pre-stack position 120 is located between the two opening and closing parts 322, the two opening and closing parts 322 are controlled to move closer to each other, so that the hook part 324 of the hook part 323 enters under the adhesive paper 20. Then the robotic arm 320 moves upward, and the hook part 324 will lift the bottom of the adhesive paper 20 to achieve the transfer of the adhesive paper 20. When the adhesive paper 20 moves to the stacked adhesive paper 20, the two opening and closing parts 322 are controlled to move away from each other, and the adhesive paper 20 will fall into the stacked adhesive paper 20, completing the transfer of the adhesive paper 20.

[0098] Specifically, the robotic arm 320 also includes an opening / closing screw 335 mounted on the frame 321. The opening / closing screw 335 extends longitudinally along the rotation axis and is rotatable about its own axis. One end of the opening / closing screw 335 is provided with a first threaded section, and the other end is provided with a second threaded section. The first threaded section and the second threaded section have opposite directions of rotation. Each opening / closing component 322 is provided with an opening / closing threaded hole, one of which is threadedly connected to the first threaded section, and the other opening / closing threaded hole is threadedly connected to another second threaded section.

[0099] To prevent the opening / closing member 322 from rotating around the screw, the frame 321 also includes a guide rod 340 extending longitudinally along the rotation axis. The guide rod 340 is slidably connected to the two opening / closing members 322 to limit the movement of the opening / closing members 322, ensuring that the opening / closing members 322 can only move along the direction of the screw. Thus, by rotating the opening / closing screw 335 clockwise or counterclockwise, the two opening / closing members 322 can be moved closer to or further apart.

[0100] Specifically, the robotic arm 320 also includes an opening and closing motor 360 and two drive wheels 361 mounted on the frame 321. One drive wheel 361 is connected to the opening and closing motor 360, and the other drive wheel 361 is connected to the opening and closing screw 335. The two drive wheels 361 are connected by a belt, thereby transmitting the power of the opening and closing motor 360 to the opening and closing screw 335 to drive the opening and closing screw 335 to rotate forward or in reverse.

[0101] In practical use, when two or more stacks of adhesive paper 20 are stacked on the stacking pallet 400, it is often necessary to place a spacer paper 40 on top of the adhesive paper 20 after the stacking of adhesive paper 20 has reached a certain height. The spacer paper 40 covers the top of both stacks of adhesive paper 20. After that, adhesive paper 20 is continued to be stacked on top of the two stacks of adhesive paper 20. The spacer paper 40 can make the two stacks of adhesive paper 20 and the newly stacked adhesive paper 20 mutually restrain each other to prevent the stacked adhesive paper 20 from falling over. Based on this, in some embodiments of this application, the robotic arm 320 is also provided with a paper suction device 350. The paper suction device 350 is used to pick up the spacer paper 40 and place the spacer paper 40 on the stacked adhesive paper 20 through the movement of the robotic arm 320, and then continue to stack the adhesive paper 20.

[0102] This application also provides a material receiving method based on the above-mentioned material receiving equipment, comprising the following steps:

[0103] S1: Stack one or more piles of laminated paper;

[0104] Specifically, if Figure 10 As shown, after the robotic arm 320 grasps and stacks the adhesive paper 20 to a certain height, step S2 can be performed;

[0105] S2: When two or more stacks of adhesive paper 20 are stacked, a separator paper 40 will be sucked up;

[0106] Specifically, if Figure 11 As shown, a sheet of divider paper 40 is picked up by the paper suction device 350 and moved.

[0107] S3: Place the interlayer paper on top of two or more stacks of laminated paper 20;

[0108] Specifically, if Figure 12 As shown, the separator paper 40 is picked up by the suction device and placed on two piles of laminated paper 20, so that the two piles of laminated paper 20 are mutually pulled together to prevent them from falling over.

[0109] S4: Continue to stack the bonding paper 20 on the interlayer paper 40.

[0110] Specifically, if Figure 13 As shown, the continuously stacked adhesive paper 20 will be pulled together by the interlayer paper 40 to prevent it from falling over.

[0111] The interlayer paper 40 allows the two stacks of laminated paper 20 and the newly stacked laminated paper 20 to pull each other together, preventing the stacked laminated paper 20 from falling over. This allows more laminated paper 20 to be stacked at once, improving the transport efficiency of the laminated paper 20.

[0112] Specifically, step S2 includes:

[0113] Take the topmost sheet of one of the stacks of laminated paper 20 and use it as a separator 40.

[0114] like Figure 11 As shown, step S2 eliminates the need to additionally extract the interlayer paper 40; the top layer of the stack of adhesive papers 20 can be used directly as the interlayer paper 40, which not only improves stacking efficiency but also saves costs.

[0115] 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.

[0116] The embodiments described above are merely illustrative of 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.
