Description

Technical Field

[0001] This invention relates to the field of packaging technology, and in particular to sheet packaging methods and corresponding sheet packaging devices. Background Technology

[0002] In the prior art, when placing sheet-like objects such as electronic tags into a packaging box, a cross-shaped inner divider is usually inserted into the packaging box, dividing the inner cavity of the packaging box into four smaller cuboid spaces, and then the sheet-like objects such as electronic tags are respectively placed into the four smaller cuboid spaces.

[0003] However, the two cardboard pieces for the inner divider of the packaging box and the cross are usually made in a printing plant and then transported to the packaging site as sheet materials. Therefore, it is necessary to set up a process to assemble the two cardboard pieces for the inner divider of the cross and a process to put the inner divider of the cross into the packaging box, which makes the manufacturing process of the packaging box complicated. In addition, the packaging box and the inner divider of the cross are separate from each other, and the inner divider of the cross is easy to fall off during recycling. Furthermore, there is room for further standardization of the shape of the packaging box and sheet materials such as electronic tags. Summary of the Invention

[0004] One object of the present invention is to solve or alleviate the above-mentioned technical problems.

[0005] The present invention employs a sheet packaging method, which is used to package sheet materials into a packaging box through a box mold assembly;

[0006] Its features include a box mold assembly including a base, on which a fixed inner partition and a movable inner partition are directly or indirectly disposed, perpendicular to the rotating seat, the movable inner partition being perpendicular to the fixed inner partition and capable of rising and falling relative to the base; the packaging box includes a box side wall, short box lids and long box lids, the top and bottom ends of the box side wall being four short box lids and two long box lids respectively; the short box lids include an inner partition, and the long box lids include a locking part;

[0007] The method for packaging sheet-like materials includes the following steps;

[0008] The folded packaging box is opened to form a square-shaped packaging box, and the square-shaped packaging box is placed on the fixed inner partition and the movable inner partition of the box mold assembly;

[0009] Fold the inner partition at the bottom of the rectangular packaging box and the short lid to form the first layer of sealed packaging box;

[0010] The sheet-like objects are placed into the space formed by the fixed inner partition, the movable inner partition, and the first layer of the sealed bottom box.

[0011] The folding box consists of the inner partition at the top of the first sealed bottom packaging box and the short box lid, forming the first sealed packaging box.

[0012] After moving the movable inner partition down, fold the top of the first sealed packaging box and the long box cover, so that the insert is inserted between the two short box covers at the top of the packaging box to form the second sealed packaging box.

[0013] After lifting the second sealed packaging box, fold the bottom of the second sealed packaging box and the long box cover, so that the bottom of the bottom of the packaging box is inserted between the two short box covers, forming a second sealed packaging box.

[0014] Output the second layer of sealed packaging box.

[0015] The advantages of this invention are that it eliminates the need for additional cross dividers inside the box, simplifies the manufacturing process of the packaging box, facilitates recycling of the packaging box, and is relatively green and environmentally friendly; furthermore, it eliminates the need to flip the packaging box during implementation, which reduces the risk of damage caused by collisions between sheet-like objects and ensures the uniformity of the posture of each packaging box and sheet-like object.

[0016] The present invention employs a sheet packaging device for implementing the aforementioned sheet packaging method. The device includes a box mold assembly and a frame. The frame includes a frame carrier and a box mold translation device mounted on the frame carrier. The frame carrier is sequentially equipped with a box feeding assembly, a folded-down bottom box cover assembly, a boxing device, a folded-down top box cover assembly, a folded-up top box cover assembly, and a folded-up bottom box cover assembly. The box mold translation device drives the base to translate, causing the box mold assembly to sequentially pass through the box feeding assembly, the folded-down bottom box cover assembly, the boxing device, the folded-down top box cover assembly, the folded-up top box cover assembly, and the folded-up bottom box cover assembly.

[0017] A further technical solution includes a base with a workstation locking hole; the frame includes a locking hook rod with rotational power, and multiple workstation locking hooks are fixedly installed on the locking hook rod, which can be inserted into the workstation locking hole.

[0018] It can ensure that the box mold components are accurately positioned at the workstation, and ensure the accuracy of folding the packaging box.

[0020] The folded packaging box can be continuously opened into a square tube shape.

[0021] A further technical solution includes a box mold lifting device, a lower carrier, and an upper carrier with lifting holes. The box mold translation device includes an upper translation device on the upper carrier and a lower translation device on the lower carrier. The box mold lifting device consists of two lifting ends with lifting holes facing each other. The lifting ends used to raise the box mold assembly face the forming frame. The forming frame can move along the conveying direction perpendicular to the box mold translation device.

[0022] It enables the box mold components to be reused while ensuring that the packaging box fits accurately onto the fixed and movable inner dividers.

[0023] A further technical solution is that the folded-down box cover assembly includes an inner support component for the folded-down box, a movable outer clamping component, an inner divider component, and a curved short box cover component; the inner support component and the movable outer clamping component both have lifting power, and the inner divider component and the curved short box cover component each have power perpendicular to the conveying direction of the box mold translation device.

A power conversion box that is driven and connected to the rotating seat is provided on the base. The rotating seat is provided with a fixed inner partition and a movable inner partition that are perpendicular to the rotating seat. The movable inner partition is perpendicular to the fixed inner partition. The boxing pusher plate has power along the conveying direction perpendicular to the boxing mold translation device. The output end of the rotating seat power component can be directly opposite the power conversion box to drive the rotating seat to rotate.

[0026] It can ensure that the height of the entire machine does not increase due to robotic arms, etc., and can increase the total volume of sheet-like items that are packed into the packaging box each time, thereby improving the versatility of the equipment.

[0027] A further technical solution involves a cylinder as the power component for the rotating seat. The rotating seat is equipped with a rotating shaft and is hinged to the base via the rotating shaft. A gear is fixedly mounted on the rotating shaft. The power conversion box is equipped with a power input hole and contains a rack that meshes with the gear. The rack is held by a spring and tends to move toward the power input hole. The output end of the rotating seat power component can pass through the power input hole and push the rack inside the power conversion box. The boxing device also includes a rotating seat limiting frame, which can abut against the rotating seat to ensure that the rotating seat tilts upward.

[0028] It can ensure that the rotating seat and the packaging box on it tilt upward at a stable angle, thereby ensuring that the bottom wall of the boxing collection groove is accurately aligned with the packaging box, and that the sheet-like material can smoothly enter the packaging box.

[0029] A further technical solution is that the folding top box cover assembly includes a folding top box inner support, a folding top box pre-folding component, and a bending short top box component; the folding top box inner support has lifting power, and the folding top box pre-folding component and the bending short top box component each have power perpendicular to the conveying direction of the box mold translation device.

[0030] It can easily form a packaging box with the first layer of sealing.

[0031] A further technical solution includes a folding elongated top box cover assembly comprising a movable folding insert fixed mold, a fixed folding insert fixed mold, a bent elongated top box cover, an insertion power component, and an insertion guide post; the movable folding insert fixed mold and the bent elongated top box cover each have power along the conveying direction of the box mold translation device, the insertion power component has lifting power, and the insertion guide post has power perpendicular to the conveying direction of the box mold translation device; the gap between the insertion guide post and the fixed inner partition can be aligned with the gap between the two short top boxes; the base or rotating seat is provided with an extension body, the extension body is linearly slidably connected to a movable component, the movable component is fixedly connected to the movable inner partition, the movable component is provided with a movable component guide shaft and has a tendency to approach the movable component; the frame is provided with a movable inner partition guide groove, the movable component guide shaft can enter the movable inner partition guide groove, the movable inner partition guide groove includes a guide groove high section and a guide groove low section, the guide groove low section is aligned with the folding elongated top box cover assembly;

[0032] And / or, the folding elongated box cover assembly includes a movable support body, a movable mold for the folding insertion part, a fixed mold for the folding insertion part, a bent elongated box cover component, an insertion power component, and an insertion guide post; the movable mold for the folding insertion part and the bent elongated box cover component are respectively powered along the conveying direction of the box mold translation device, the insertion power component is powered by lifting and lowering and is provided with a lower support claw and an upper support claw, the lower support claw, the upper support claw, the movable support body, and the insertion guide post are respectively powered perpendicular to the conveying direction of the box mold translation device, and the gap between the insertion guide post and the fixed inner partition can be aligned with the gap between the two short box covers.

[0033] The movable inner partition has been lowered without obstructing the insert, making it easy to form a second-layer sealed packaging box; the long box lid and insert at the bottom of the packaging box can be folded without flipping the packaging box to form a second-layer sealed packaging box.

Detailed Implementation

[0064] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0065] The terms used in this invention, such as "first," "second," "long," and "short," do not indicate any order, quantity, or importance; they are merely for distinction. Terms indicating direction or location, such as "top," "bottom," "side," "vertical," "horizontal," "middle," "center," "outer," "inner," "horizontal," "vertical," "left," "right," "above," and "below," indicate relative positions, not absolute positions.

[0066] As a specific embodiment, the sheet packaging method of the present invention is used to package the sheet 7 into the packaging box 6 through the box mold assembly 8.

[0067] The sheet-like object 7 is an electronic ink screen label, etc., which is usually a thin cuboid shape.

[0068] like Figure 9-12As shown, the box mold assembly 8 includes a base 81 and a rotating seat 82 hinged to the base 81. For example, the base 81 and the rotating seat 82 are hinged via a rotating shaft 828 and a bearing seat (not shown in the figure). The base 81 is provided with a translation part 811 and a power conversion box 83 driven and connected to the rotating seat 82. The translation part 811 is used to connect with the box mold translation device 92, so that the box mold translation device 92 can drive the box mold assembly 8 to translate through the translation part 811. Typically, both the box mold translation device 92 and the translation part 811 are provided with several protrusions to ensure translation drive. The transmission of power involves a rotating shaft 828 with a fixed gear 832. A power conversion box 83 has a power input hole 831 and contains a rack that meshes with the gear 832. The rack is held by a spring and tends to move towards the power input hole 831. The output end of the rotating seat power component 95 passes through the power input hole 831 and pushes the rack inside the power conversion box 83, causing the rotating seat 82 to rotate. After the rotating seat power component 95 resets, the rotating seat 82 also resets. Alternatively, the meshing of the gear 832 and rack can be replaced by other methods such as power transmission through friction. The rotating seat 82 has a fixed inner partition 84 and a movable inner partition 85 perpendicular to it. The movable inner partition 85 is perpendicular to the fixed inner partition 84. Viewed perpendicularly from the rotating seat 82, the movable inner partition 85 and the fixed inner partition 84 are perpendicular to each other, forming a cross-shaped arrangement. The movable inner partition 85 and / or the fixed inner partition 84 have gaps to avoid mutual interference. The fixed inner partition 84 is fixedly connected to the rotating seat 82. The rotating seat 82 is provided with an extension body 825, and a movable component 851 is linearly slidably connected to the extension body 825. For example, the movable component 851 is linearly slidably connected to the extension body 825 through a slider and slide rail structure. The movable component 851 is fixedly connected to the movable inner partition 85, and the movable component 851 is provided with a movable component guide shaft 852 and has a tendency to move closer to the movable component 851. For example, the movable component 851 and the rotating seat 82 are connected to the rotating shaft 828 through a movable inner partition elastic component 853 that provides tension, so that the movable component 851 has a tendency to move closer to the movable component 851. It is easy to understand that when the movable component 851 slides linearly along the extension body 825, it will drive the movable inner partition 85 to slide linearly. The movable component guide shaft 852 is used to cooperate with the movable inner partition guide groove 96 described later to realize the control of the height position of the movable component 851 and the movable inner partition 85. Typically, a buffer 818 is provided on the base 81 and / or the rotating seat 82 to ensure the angle between the base 81 and the rotating seat 82. Typically, a slider 819 is fixedly provided on the base 81, and the slider 819 cooperates with the translation guide 929 described later to ensure the stability of the box mold assembly 8 during translation.

[0069] It should be noted that the rotating seat 82 is provided to temporarily tilt the fixed inner partition 84 and the movable inner partition 85, facilitating the placement of the sheet 7 into the packaging box 6 by the boxing device 3 in this embodiment of the invention. However, in embodiments where the boxing device 3 is a robotic arm or similar device, it is not necessary to temporarily tilt the fixed inner partition 84 and the movable inner partition 85, thus eliminating the need for the rotating seat 82 and the power conversion box 83 for its rotation. Therefore, what is necessary for implementing the sheet packaging method of this embodiment of the invention is that the box mold assembly 8 includes a base 81, on which a fixed inner partition 84 and a movable inner partition 85, perpendicular to the rotating seat 82, are directly or indirectly disposed, with the movable inner partition 85 perpendicular to the fixed inner partition 84 and capable of rising and falling relative to the base 81. For example, the fixed inner partition 84 is directly fixed on the base 81, the base 81 is provided with an extension body 825, the extension body 825 is linearly slidably connected to a movable part 851, the movable part 851 is fixedly connected to the movable inner partition 85, the movable part 851 is provided with a movable part guide shaft 852 and has a tendency to approach the movable part 851, so that the fixed inner partition 84 and the movable inner partition 85 perpendicular to the rotating seat 82 are directly provided on the base 81; while the aforementioned structure with the rotating seat 82 is a structure in which the fixed inner partition 84 and the movable inner partition 85 perpendicular to the rotating seat 82 are indirectly provided on the base 81.

[0070] like Figure 7 As shown, the packaging box 6 is typically made of paper and includes a box side wall 61, short lids 62, and long lids 63. The top and bottom ends of the box side wall 61 have four short lids 62 and two long lids 63, respectively. Each short lid 62 includes an inner divider 621, and each long lid 63 includes a locking part 631, totaling eight short lids 62 and four long lids 63. When unfolded, the packaging box 6 is a flat surface. By fixing the box connecting part 611 on the box side wall 61 to the other end of the box side wall 61 (e.g., by gluing and then flattening), the packaging box 6 becomes a folded packaging box 6. Figure 14 As shown, the folded packaging box 6 has two layers, each with four short lids 62 and two long lids 63 (and half the total number mentioned above). The folded packaging box 6 is typically manufactured in a cardboard box factory because its thinness facilitates stacking and transportation to the sheet packaging unit, where it is then placed... Figure 14 The box stacking device 12 shown enables continuous single-piece feeding of folded packaging boxes 6. The continuous single-piece feeding of folded packaging boxes 6 using the box stacking device 12 is existing technology. For example, the box stacking device 12 includes an inclined stacking frame 121, on which are provided elastic box guide strips 122 and box pushers 123 that tend to move closer to the box guide strips 122. The stacked folded packaging boxes 6 are held between the box pushers 123 and the box guide strips 122. Combined with the box opening device 11 described later, continuous single-piece feeding and opening of the packaging boxes 6 are achieved.

[0071] like Figure 8 As shown, the short lid 62, after folding, becomes the first lid at the top and bottom of the packaging box 6. The inner partition 621 of the short lid 62 forms an inner partition within the box, and a lid slot 622 is formed between the two short lids 62. The long lid 63, after folding, becomes the second lid at the top (covering the first lid at the top) and the second lid at the bottom of the packaging box 6. The insertion part 631 of the long lid 63 is inserted into the lid slot 622 to hold the long lid 63 in its position. The insertion part 631 and the inner partition 621 form a cross-shaped inner partition within the packaging box 6, which divides a rectangular space within the packaging box 6 into four smaller rectangular spaces. In summary, the sheet packaging method and apparatus of the embodiments of the present invention aim to place the sheet 7 into the packaging box 6, and distribute the sheet 7 within the four smaller rectangular spaces; in other words, the cross-shaped inner partition divides the sheet 7 into four smaller rectangular spaces.

[0072] The sheet packaging method of the present invention includes the following steps;

[0073] The box opening device 11 opens the folded packaging box 6 to form a square-shaped packaging box 6, and then puts the square-shaped packaging box 6 onto the fixed inner partition 84 and the movable inner partition 85 of the box mold assembly 8. It should be noted that after the packaging box 6 is put onto the fixed inner partition 84 and the movable inner partition 85, the fixed inner partition 84 is perpendicular to the short box cover 62, and the movable inner partition 85 is perpendicular to the long box cover 63.

[0074] The inner partition 621 and the short lid 62 at the bottom of the cylindrical packaging box 6 are folded by the short bottom box lid assembly 2 to form a first-layer sealed packaging box 6. It should be noted that at this time, the bottom of the first-layer sealed packaging box 6 is sealed and can hold sheet-like objects 7.

[0075] After the boxing device 3 completes the process of placing the sheet material 7 into the space formed by the fixed inner partition 84, the movable inner partition 85, and the first-layer sealed packaging box 6, it should be noted that the first-layer sealed packaging box 6 contains the sheet material 7, and the sheet material 7 is separated by the fixed inner partition 84 and the movable inner partition 85.

[0076] The inner partition 621 at the top of the folded top cover assembly 4 and the short cover 62 form the first layer of sealed packaging box 6. It should be noted that this seal means that the top and bottom of the packaging box 6 are covered by the short cover 62 to form the first layer of seal, and the inner partition 621 separates the sheet-like objects 7 inside the packaging box 6. It should be noted that at this time, the inner partition 621 is in contact with the movable inner partition 85, so the sheet-like objects 7 are separated by the inner partition 621 and the fixed inner partition 84.

[0077] After the movable inner partition 85 is moved down by the folding top cover assembly 51, the insertion part 631 at the top of the first layer of sealed packaging box 6 and the long box cover 63 are folded, so that the insertion part 631 is inserted between the two short box covers 62 at the top of the packaging box 6, forming the second layer of sealed packaging box 6. It should be noted that if the movable inner partition 85 is not moved down, the top of the movable inner partition 85 will block the insertion part 631 at the top of the first layer of sealed packaging box 6 from being inserted between the two short box covers 62 at the top of the packaging box 6, at which time the insertion parts 631 are in contact with each other.

[0078] After the folding bottom cover assembly 52 lifts the second-layer sealed packaging box 6, the inserting part 631 and the long cover 63 at the bottom of the second-layer sealed packaging box 6 are folded, so that the inserting part 631 is inserted between the two short covers 62 at the bottom of the packaging box 6, forming a second-layer sealed packaging box 6. It should be noted that the second layer of sealing means that the top of the packaging box 6 is sealed by the two layers of short covers 62 and long covers 63. At this time, the inner partition 621 and the inserting part 631 are arranged perpendicularly to each other inside the packaging box 6. A cross-shaped partition is formed, and the inserting part 631 is inserted into the lid slot 622 between the two short lids 62 and held in position, so that the packaging box 6 and the sheet 7 inside are in a relatively stable state. It should also be noted that if the packaging box 6 is not lifted, the bottom of the packaging box 6 is placed on the rotating seat 82, and the fixed inner partition 84 and the movable inner partition 85 are both inserted into the packaging box 6, which makes it impossible to insert the inserting part 631 at the bottom of the second-layer sealed packaging box 6 between the two short lids 62 at the bottom of the packaging box 6.

[0079] The second-sealed packaging box 6 is output. This step is completed by the output device 98.

[0080] Repeating the above process continuously packages the sheet material 7 into the packaging box 6. As can be seen from the above, the sheet material packaging method of the embodiment of the present invention does not require additional cross dividers inside the box, which simplifies the manufacturing process of the packaging box 6 and facilitates the recycling of the packaging box 6, making it more environmentally friendly; moreover, the packaging box 6 does not need to be flipped during implementation, which reduces the risk of damage caused by collision between the sheet materials 7 and ensures that the posture of each packaging box 6 and the sheet material 7 is uniform.

[0081] The sheet packaging apparatus of the present invention includes a box mold assembly 8 and a frame 9. The frame 9 includes a frame carrier 91 and a box mold translation device 92 disposed on the frame carrier 91. For example, the box mold translation device 92 is a synchronous belt driven by a motor.

[0082] The frame carrier 91 is sequentially provided with a box feeding assembly 1, a folded short bottom box cover assembly 2, a box packing device 3, a folded short top box cover assembly 4, and a folded long box cover assembly 5. The folded long box cover assembly 5 includes a folded long top box cover assembly 51 and a folded long bottom box cover assembly 52.

[0083] The box mold translation device 92 drives the base 81 to translate, so that the box mold assembly 8 passes sequentially through the box feeding assembly 1, the folded short bottom box cover assembly 2, the box packing device 3, the folded short top box cover assembly 4, the folded long top box cover assembly 51, and the folded long bottom box cover assembly 52.

[0084] As one specific implementation, the base 81 is provided with a station locking hole 812; the frame 9 includes a station locking device 94; the station locking device 94 includes a locking hook rod 942 with rotational power, for example, a locking rod cylinder 943 pushes the locking hook rod 942 to give the locking hook rod 942 rotational power, and multiple station locking hooks 941 are fixedly provided on the locking hook rod 942. The station locking hooks 941 can be inserted into the station locking hole 812, so that the box mold assembly 8 can be temporarily fixed on at least one of the corresponding stations of the box feeding assembly 1, the folded bottom box cover assembly 2, the box packing device 3, the folded top box cover assembly 4, the folded long top box cover assembly 51, and the folded long bottom box cover assembly 52. ​​This can ensure that the box mold assembly 8 is accurately positioned at the station and ensure the accuracy of folding the packaging box 6.

[0085] As one specific implementation, the box feeding assembly 1 includes a box opening device 11 and a box stacking device 12 capable of continuously outputting single pieces of the folded packaging box 6. The box opening device 11 includes an adsorption member 111 and a forming frame (not shown in the figure). The forming frame includes a forming frame end wall 114 and two forming frame side walls 113, making the forming frame U-shaped when viewed from above. The adsorption member 111 can move relative to the direction perpendicular to the forming frame end wall 114. For example, the adsorption member 111 is a suction cup or the like, capable of adsorbing the folded packaging box 6. The adsorption member 111 is connected to an adsorption moving member 112, such as a cylinder. The forming frame is connected to a forming frame moving member 115, such as a cylinder. The adsorption member 111 adsorbs the folded packaging box 6, causing the folded packaging box 6 to enter the forming frame, so that the box side walls 61 are in contact with or close to the forming frame end wall 114 and the forming frame side walls 113, respectively. At this time, the packaging box 6 is opened into a square tube shape. The folded packaging box 6 can be continuously opened into a square tube shape.

[0086] As one of the specific implementation methods, such as Figures 3 to 6As shown, the carrier 91 includes a box mold lifting device 93, a lower carrier 912, and an upper carrier 911 with lifting holes 913. The box mold translation device 92 includes an upper translation device 921 disposed on the upper carrier 911 and a lower translation device 922 disposed on the lower carrier 912. The box mold lifting device 93 consists of two lifting ends 931 with lifting holes 913 facing each other. It is easy to understand that one of the two box mold lifting devices 93 is used to lower the box mold assembly 8 and transport the box mold assembly 8 from the upper carrier 911 to the lower carrier 912. Another component of the lowering device 93 is used to raise the box mold assembly 8 and transport it from the lower carrier 912 to the upper carrier 911. The upper translation device 921 and the lower translation device 922 transport in opposite directions, forming a cyclical transport path for the box mold assembly 8. This allows the box mold assembly 8 to be used repeatedly. Meanwhile, the lifting end 931, used to raise the box mold assembly 8, faces the forming frame, which can move along the transport direction perpendicular to the box mold translation device 92. For example, the forming frame can avoid the movement of the box mold assembly 8 by moving the forming frame moving member 115. The lifting end 931 raises the box mold assembly 8, allowing the fixed inner partition 84 and the movable inner partition 85 to be inserted from the bottom of the cylindrical packaging box 6 until the long box cover 63 at the bottom of the packaging box 6 is in contact with the top surface of the base 81 or the rotating seat 82. After the forming frame moves along the conveying direction of the vertical box mold translation device 92, the box mold assembly 8, along with the cylindrical packaging box 6 fitted onto the fixed inner partition 84 and the movable inner partition 85, moves along the box mold translation device 92 to the subsequent work station. Typically, the base 81 or the rotating seat 82 is provided with a flexible and slightly inclined outer clamp 829 to ensure that the cylindrical packaging box 6 is accurately fitted onto the fixed inner partition 84 and the movable inner partition 85. This ensures that the packaging box 6 is accurately fitted onto the fixed inner partition 84 and the movable inner partition 85.

[0087] As one of the specific implementation methods, such as Figure 16As shown, the folded-down box cover assembly 2 includes an inner support member 22, a movable outer clamping member 23, an inner divider 24, and a curved short box cover member 25. Both the inner support member 22 and the movable outer clamping member 23 have lifting power; for example, the movable outer clamping member 23 is a pneumatic gripper. The folded-down box cover assembly 2 also includes a folded-down box cover carrier 21. The inner support member 22 and the movable outer clamping member 23 are connected to cylinders on the folded-down box cover carrier 21 via an inner support rod 228, thus possessing lifting power. The inner divider 24 and the curved short box cover member 25 each have power perpendicular to the conveying direction of the box mold translation device 92. Although the power direction of the curved short box cover member 25 has an angle with the horizontal plane, when viewed from above, the power direction of the curved short box cover member 25 is still perpendicular to the conveying direction of the box mold translation device 92. When the cylindrical packaging box 6 and the box mold assembly 8 are located in the folded-down box cover assembly 2, the folded-down box inner support member 22 descends and extends into the packaging box 6 until it aligns with the fold line of the inner partition 621 at the bottom of the packaging box 6. The movable outer clamping member 23 descends and slightly clamps the side wall 61 of the box. The folded inner partition member 24 moves perpendicular to the conveying direction of the box mold translation device 92. The folded inner partition member 24 pushes the inner partition 621 and cooperates with the folded-down box inner support member 22 to fold the inner partition 621. The folded-down box inner support member 22 rises until it aligns with the bottom of the packaging box 6. At the fold line of the short box cover 62, the short bottom box cover 25 is bent to push the short box cover 62 at the bottom of the packaging box 6, causing the short box cover 62 (with the inner partition 621 folded and perpendicular to the short box cover 62) to tilt. Then, the movable outer clamp 23 clamps the packaging box 6, causing the packaging box 6 to move downward as a whole. During this process, the short box cover 62 at the bottom of the packaging box 6 abuts against the base 81 or the rotating seat 82 until it is in contact with the base 81 or the rotating seat 82. The inner partition 621 is in contact with the fixed inner partition 84, thus easily forming the first layer of sealed bottom packaging box 6. Typically, a box pressing device 26 is also provided between the folded bottom box lid assembly 2 and the boxing device 3. The box pressing device 26 includes a first pressing member 261 and a second pressing member 262. Both the first pressing member 261 and the second pressing member 262 can be raised and lowered. They respectively abut against the bottom end face of the first-layer sealed bottom packaging box 6 and the top short box lid 62 of the first-layer sealed bottom packaging box 6, ensuring that the bottom end face of the first-layer sealed bottom packaging box 6 is in contact with the base 81 or the rotating seat 82 and that its position relative to the box mold assembly 8 is stable, preparing for the subsequent loading of the sheet 7 into the packaging box 6. The folded bottom box lid carrier 21 is raised and lowered by the lifting and lowering clearance member 97 to make way. It is easy to understand that in subsequent work stations, there is also a need to use the lifting and lowering clearance member 97 to make up for the lifting and lowering clearance to allow the box mold assembly 8, and to use the translation clearance member 971 to make translation clearance to allow the box mold assembly 8. The specific process of allowing the box mold assembly 8 to pass through in order to make way will not be described in detail later.

[0088] As one specific implementation, the cartoning device 3 includes a cartoning mold 31, a rotating seat power component 95, and a cartoning pusher plate 32. The cartoning mold 31 is provided with a cartoning convergence groove 312. Typically, the inlet end of the cartoning mold 31 is provided with a cartoning guide groove 311, the width of which is greater than that of the cartoning convergence groove 312, to facilitate guiding the sheet-like items 7 to the cartoning convergence groove 312 and converging them. Typically, existing sheet-like item arrangement devices 39 stack multiple sheet-like items 7 and place them on their sides (i.e., the thinner but longer side is facing down) to prepare for the subsequent process of placing the sheet-like items 7 into the packaging box 6. For example, Figure 18 As shown, the sheet arrangement device 39 is sequentially and individually picked up by the suction cup and placed onto the timing belt with attached separators, so that the sheet 7 is placed sideways and aligned with the boxing guide groove 311. As mentioned earlier, the box mold assembly 8 includes a rotating seat 82 that is also hinged to the base 81. The base 81 is provided with a power conversion box 83 that is drivenly connected to the rotating seat 82. The rotating seat 82 is provided with a fixed inner partition 84 and a movable inner partition 85 perpendicular to the rotating seat 82. The movable inner partition 85 is perpendicular to the fixed inner partition 84. The boxing pusher plate 32 has power along the conveying direction perpendicular to the box mold translation device 92. Generally, the height of the sheet 7 is higher than the height of the box mold 31, allowing the boxing pusher plate 32 to push the sheet 7. The output end of the rotating seat power member 95 can be directly facing the power conversion box 83 to drive the rotating seat 82 to rotate. The rotating seat power component 95 drives the rotating seat 82 to rotate, so that the top opening of the first-layer sealed packaging box 6 is directly aligned with the box-filling converging groove 312. The box-filling pusher plate 32 pushes the sheet 7, causing the sheet 7 to enter the first-layer sealed packaging box 6. Compared with the method of using a robotic arm or similar device to grip the sheet 7 and move it vertically downwards to place it into the packaging box 6, this method ensures that the overall height of the equipment is not increased due to the robotic arm or similar device. The grippers of the robotic arm or similar device do not need to enter the packaging box 6, which can increase the total volume of the sheet 7 that can be loaded into the packaging box 6 each time, thereby improving the versatility of the equipment.

[0089] As one specific implementation, the rotating seat power component 95 is a cylinder. As mentioned above, the rotating seat 82 is provided with a rotating shaft 828 and is hinged to the base 81 through the rotating shaft 828. A gear 832 is fixedly provided on the rotating shaft 828. The power conversion box 83 is provided with a power input hole 831 and a rack that meshes with the gear 832 is provided inside it. The rack is held by a spring and has a tendency to move toward the power input hole 831. The output end of the rotating seat power component 95 can pass through the power input hole 831 and push the rack inside the power conversion box 83. The boxing device 3 also includes a rotating seat limiting frame 951. The rotating seat limiting frame 951 can abut against the rotating seat 82 (for example, against the extension 825 on the rotating seat 82) to ensure that the rotating seat 82 tilts upward. The output end of the rotating seat power component 95 continuously abuts against the rack inside the power conversion box 83, causing the rotating seat 82 to have a rotational tendency and abut against the rotating seat limit frame 951. This ensures that the upward tilt angle of the rotating seat 82 and the packaging box 6 on it is stable, thereby ensuring accurate alignment between the bottom wall of the boxing convergence groove 312 and the packaging box 6, allowing the sheet 7 to smoothly enter the packaging box 6. The boxing mold 31 includes a lower boxing mold 37 and an upper boxing mold 38 with a height difference from the lower boxing mold 37. The lower boxing mold 37 and the upper boxing mold 38 respectively place the sheet 7 into the layer position space inside the packaging box 6. The lower boxing mold 37 is provided with a short box cover suction component 371 to prevent the short box cover 62 at the top of the packaging box 6 from tilting up and blocking the sheet 7 from entering the packaging box 6.

[0090] As one specific implementation, the folding top box cover assembly 4 includes a folding top box inner support 42, a folding top box pre-folding component 44, and a bending short top box component 45. The folding top box inner support 42 has lifting power, and the folding top box pre-folding component 44 and the bending short top box component 45 each have power perpendicular to the conveying direction of the box mold translation device 92. As mentioned above, the folding top box cover assembly 4 folds the inner partition 621 at the top of the first-layer sealed packaging box 6 and the short box cover 62 to form the first-layer sealed packaging box 6. The operation of the folded top cover assembly 4 is similar to that of the folded bottom cover assembly 2, except that the inner support 42 of the folded top cover will rise after engaging with the inner partition 621 at the top of the folded packaging box 6. Then, the inner support 42 of the folded top cover will press down on the short cover 62 at the top of the packaging box 6 again, so that the short cover 62 seals the top of the packaging box 6. Therefore, the packaging box 6 does not need to move up and down, and the folded top cover assembly 4 does not require the movable outer clamp 23 of the folded bottom cover assembly 2. For other processes, please refer to the operation of the folded bottom cover assembly 2, which will not be repeated here. The folded top cover carrier 41 of the folded top cover assembly 4 is connected to the long cover outer support 46. The long cover outer support 46 is used to slightly open the long cover 63 at the top of the packaging box 6 outward, which can easily form the first layer of sealed packaging box 6.

[0091] As one specific implementation, the folding elongated top cover assembly 51 includes a movable folding and inserting fixed part mold 53, a fixed folding and inserting fixed part mold 531, a bent elongated cover part 54, an insertion power member 55, and an insertion guide post 551; the movable folding and inserting fixed part mold 53 and the bent elongated cover part 54 are respectively provided with power along the conveying direction of the box mold translation device 92, the insertion power member 55 is provided with lifting power, the insertion guide post 551 is provided with power perpendicular to the conveying direction of the box mold translation device 92, and the gap between the insertion guide post 551 and the fixed inner partition 84 (the horizontal gap when viewed from above) can be directly aligned with the gap between the two short cover 62 (i.e., the cover slot 622). The base 81 or rotating seat 82 is provided with an extension body 825, which is linearly slidably connected to a movable part 851. For example, the movable part 851 is linearly slidably connected to the extension body 825 via a slider or slide rail structure. The movable part 851 is fixedly connected to the movable inner partition 85. The movable part 851 is provided with a movable part guide shaft 852 and tends to move closer to the movable part 851. The frame 9 is provided with a movable inner partition guide groove 96, and the movable part guide shaft 852 can enter the movable inner partition guide groove 96. The movable inner partition guide groove 96 includes a high section 961 and a low section 962, with the low section 962 facing the folded long top box cover assembly 51. It is easy to understand that the movable mold 53 of the folding insertion fixed part, the fixed mold 531 of the folding insertion fixed part, the bending long box cover part 54 (which makes way through the bending long box cover carrier 541), the insertion guide post 551 need to move to make way, and the insertion power part 55 needs to be raised and lowered to make way. The elongated top cover assembly 51 is also equipped with an insert inner support 511; this ensures that when the inserting power component 55 presses down on the elongated top cover 63 of the packaging box 6, it will not move downwards excessively and damage the sheet-like objects 7 inside the packaging box 6. Figure 23As shown, when the box mold assembly 8 moves to the station where the folded top box cover assembly 51 is located, the lower section 962 of the guide groove abuts against the movable guide shaft 852, causing the movable inner partition 85 to move downward (usually, the movable inner partition 85 is provided with a movable inner partition protrusion 859 for limiting). In the folded top box cover assembly 51, after the folding insert fixing mold 531 aligns with the folding line of the top insert 631 of the packaging box 6, the folding insert movable mold 53 moves along the conveying direction of the box mold translation device 92 to fold the top insert 631 of the packaging box 6. Then, the bending long box cover 54 moves along the conveying direction of the box mold translation device 92 to bend the long box cover 63 at the top of the packaging box 6 (during this bending process, if the inner partition 621 is inserted between the insertion guide post 551 and the fixed inner partition 84, the long box cover 63 will remain bent and the inner partition 621 will be pre-aligned). The insertion force 55 moves downward and directly abuts the long box cover 63 at the top of the packaging box 6. The insertion guide post 551 moves vertically in the conveying direction of the box mold translation device 92 and overlaps with the fixed inner partition 84 (or the fixed inner partition 84 is inserted between the two insertion guide posts 551). This allows the insertion part 631 to continue passing through the gap between the insertion guide post 551 and the fixed inner partition 84 and continue to press down until the second layer of the packaging box 6 is formed. At this time, the movable inner partition 85 has descended and will not block the insertion part 631, which can easily form the second layer of the packaging box 6.

[0092] And / or, the folding elongated box cover assembly 52 includes a movable support body 521, a movable mold 53 for the folding insertion part, a fixed mold 531 for the folding insertion part, a curved elongated box cover 54, an insertion power member 55, and an insertion guide post 551; the movable mold 53 for the folding insertion part and the curved elongated box cover 54 are respectively provided with power along the conveying direction of the box mold translation device 92, the insertion power member 55 is provided with lifting power and is provided with a lower support claw 522 and an upper support claw 523, the lower support claw 522, the upper support claw 523, the movable support body 521, and the insertion guide post 551 are respectively provided with power perpendicular to the conveying direction of the box mold translation device 92, and the gap between the insertion guide post 551 and the fixed inner partition 84 can be aligned with the gap between the two short box covers 62 (i.e., the box cover slot 622). When the box mold assembly 8 moves to the station where the folded bottom box cover assembly 52 is located, the insertion power component 55 moves downward and the lower support claw 522 and upper support claw 523 approach the packaging box 6. After the lower support claw 522 supports the bottom end of the packaging box 6, the lower support claw 522 and upper support claw 523 move upward and lift the packaging box 6 as a whole. This aligns the folding and fixing part fixing mold 531 with the folding line of the bottom fixing part 631 of the packaging box 6. Then, the folding and fixing part movable mold 53 moves along the conveying direction of the box mold translation device 92 to fold the bottom fixing part 631 of the packaging box 6, and then bends the long box. The lid 54 moves along the conveying direction of the box mold translation device 92, causing the long lid 63 at the bottom of the packaging box 6 to bend. Then, the movable support 521 moves perpendicularly to the conveying direction of the box mold translation device 92 to below the bottom of the packaging box 6. Then, the insertion power member 55 moves downward, causing the upper support claw 523 to abut against the packaging box 6 and move downward. The movable support 521 abuts against the long lid 63 (already bent) at the bottom of the packaging box 6, causing the insertion part 631 to continue to pass through the gap between the insertion guide post 551 and the fixed inner partition 84 and continue to press down until a second layer of sealed packaging box 6 is formed. The long lid 63 and the insertion part 631 at the bottom of the packaging box 6 can be folded to form a second layer of sealed packaging box 6 without flipping the packaging box 6.

[0093] Afterwards, the second-sealed packaging box 6 is completed. It is then transported to the next station using conventional methods such as a track. The gripper 981 of the output device 98 lifts the second-sealed packaging box 6 and transports it to another location. The box mold assembly 8 continues to move to the lifting hole 913 and then descends, ready for reuse. Repeating the above process allows for the continuous packaging of sheet-like objects 7 into packaging boxes 6.
