Description

Technical Field

[0001] This application relates to the field of packaging equipment technology, and in particular to packaging systems and methods for box-shaped items. Background Technology

[0002] In daily life and business activities, various products require packaging for transportation and display. Due to environmental and economic factors, recyclable paper is often used as the primary material for packaging boxes. Paper's sheet-like structure and flexible, foldable nature allow for stacking and bundling of boxes during transport, minimizing space requirements and facilitating large-volume shipments. Secondly, sheet-like plastics and other flexible, foldable sheet materials are also used. These packaging boxes are transported by folding multiple individual units, stacking them, and securing them with straps. However, these materials are prone to breakage and lack structural support, necessitating the addition of protective materials and securing them. Currently, due to the varying shapes and sizes of packaging boxes, most methods involve manually applying protective materials, followed by manual bundling, resulting in low efficiency and high costs. Summary of the Invention

[0003] Therefore, it is necessary to provide an automated and highly efficient packaging system and method for boxed items to address the above problems.

[0005] The support device includes a worktable and a bracket supporting the worktable, the worktable having a working surface and a working area for packaging box-shaped items; and

[0006] A conveying device is drivenly connected to the support and located above the working plane. The conveying device is used to pick up and convey the corner protector. At least a portion of the corner protector is located below the working plane. Before the conveying device conveys the corner protector to the working area, the portion of the corner protector located below the working plane is bent by the workbench to match the corner shape of the box-shaped object.

[0007] In one embodiment, the conveying device is capable of moving relative to the worktable in a first direction to the work area; the conveying device includes a picking component and a rotating component, the picking component being used to fix the corner protector, and the rotating component being used to drive the picking component and the corner protector to rotate about a second direction, the first direction being parallel to the work plane, and the second direction being perpendicular to the work plane.

[0008] In one embodiment, the packaging system further includes a drive assembly comprising a guide rod slidably connected to the support and a drive motor, the conveying device being connected to the guide rod, and the drive unit driving the guide rod to move the conveying assembly along a first direction parallel to the working plane.

[0009] In one embodiment, the support includes support columns and a gantry frame. The gantry frame is spaced apart from the working plane and connected between adjacent support columns. A lead screw is provided inside the gantry frame along the first direction. One end of the guide rod is connected to the lead screw. The drive motor drives the lead screw to rotate. A limiting member is provided on the lead screw, and the limiting member is positioned corresponding to the working area.

[0010] In one embodiment, the conveying device includes a folding assembly, which conveys the corner protector to the work area and places the box-shaped object after the corner protector is in place, the folding assembly being used to bend the portion of the corner protector that extends beyond the box-shaped object toward the box-shaped object.

[0011] In one embodiment, the folding assembly includes a power unit and a folding arm, the folding arm being spaced apart from the worktable, the power unit being used to drive the folding arm to rotate relative to the work plane and / or move along a first direction to bend the portion of the edge protector that extends beyond the box-shaped object.

[0012] In one embodiment, the working plane is recessed with a strapping groove for the strapping tape to pass through.

[0013] In one embodiment, the packaging system further includes a storage component for storing corner protectors, the outlet of which is located on one side of the workbench; the storage component includes a feeding track and a pusher, the corner protectors are disposed on the feeding track, the feeding track is inclined relative to the working plane, the pusher abuts against the side of the corner protector away from the outlet, and the pusher is slidably connected to the feeding track.

[0014] A method for packaging box-shaped items, using the packaging system described above, includes the following steps:

[0015] Take the corner protector, with at least a portion of the corner protector being taken below the working plane;

[0016] Before the corner protector is conveyed to the work area, the portion of the corner protector located below the work plane is bent by the workbench to match the corner shape of the box-shaped object;

[0017] The bent corner protector moves to the work area, and the box-shaped object is placed on the corner protector.

[0018] In one embodiment, after the step of placing the box-shaped object on the corner protector, the method further includes:

[0019] The portion of the corner protector that extends beyond the box-shaped object is bent toward the box-shaped object;

[0020] And / or, by passing strapping tape between the box and the working surface, the box and the corner protector are bundled together.

[0021] The aforementioned packaging system and method, by setting up a conveyor device, automatically picks up and transports corner protectors to the work area for packaging box-shaped items, thereby improving the work efficiency of the packaging process. At the same time, through the cooperation of the conveyor device and the worktable, when picking up or transporting corner protectors, the corner protectors are bent into a shape that matches the corners of the box-shaped items by taking advantage of the difference in their placement. The process of picking up, bending, and packaging is seamless and the structure is simple, which improves efficiency without increasing the overall cost. Attached Figure Description

Detailed Implementation

[0026] 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.

[0027] 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.

[0028] 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.

[0029] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] 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.

[0031] 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.

[0032] The term "box-shaped object" as used in this application refers to an article with a specific spatial configuration, and does not specifically refer to the shape of the article. Box-shaped objects are especially products already packaged in boxes or the boxes themselves. The packaging system and method of this application are particularly aimed at box-shaped objects with sharp edges. Preferably, the box-shaped object can be a paper box.

[0033] Among the main materials used for packaging boxes, such as paper, plastic, and wood, composite materials made by bonding aesthetically pleasing printed cardboard and reinforced corrugated paper with adhesives offer the best load-bearing capacity and are therefore the most widely used, found in every aspect of life. This is because it not only provides aesthetic protection for the product but also has the ability to support its own weight.

[0034] In actual production, the composite material, made by bonding attractive printed cardboard and reinforcing corrugated paper with adhesive, needs to be cut into box patterns before being folded and glued into packaging boxes. Therefore, in the box pattern cutting process, only the useful parts of the composite material required for the packaging box design are retained, while the rest are cut off. After cutting, the box pattern, in the process of gluing it into the packaging box, has overlapping joints as well as separate cut surfaces. The cut surfaces clearly show the components of the composite material: the attractive printed cardboard and the reinforcing corrugated paper are tightly bonded together with adhesive, creating distinct layers.

[0035] Once the paper pattern has been folded into a box suitable for packaging a specific product through the gluing process, production workers will stack a certain number of these boxes on a bundling platform. The stack is typically at a height that a person can comfortably hold with their open hand. The bundling straps must pass under the stacked boxes and be positioned symmetrically on the left and right sides (for ease of description, the direction of the bundling straps is tentatively defined as the left-right direction of the platform where the stack is placed, and the direction perpendicular to the bundling straps is defined as the front-back direction of the platform).

[0036] Research has revealed two traditional methods: one involves using pre-formed corner protectors to wrap box-shaped items before bundling; the other involves directly wrapping the items with unfolded corner protectors before bundling. With corner protectors, the product won't be damaged by the bundling straps. The exposed edges of paper boxes, especially the printed cardboard and bonded corrugated cardboard, are most susceptible to tearing and bursting due to the strapping straps, resulting in waste. Furthermore, the ink patterns or text on the corners of printed paper boxes can also be marked or damaged by the strapping straps, leading to further waste. Bundling straps prevent products from falling apart and facilitate handling and storage.

[0037] The first method described above is not suitable for irregularly shaped boxes or boxes with non-standard corner angles, limiting its applicability. If the corner protectors are not properly fitted, forceful bundling will affect their protective effect on the box, potentially leading to issues such as material detachment or product displacement during transport.

[0038] For the second method, it is usually done manually. The operator needs to manually lift the stack and then use corner protectors to cover the edges of the top and bottom surfaces of the stack. The corner protectors are symmetrically placed in the left-right direction, covering the sides, top corners, and bottom corners. After covering one side, the other side is covered. Once both sides are covered, both hands are used to hold the corner protector vertically upwards, pressing it firmly against the top surface of the stack (the bottom of the corner protector is naturally held down by the weight of the stack). Then, the stack can be placed into a strapping machine to attach straps and complete the work. Alternatively, another operator can assist, with one person lifting the stack with corner protectors while the other manually passes the straps under the stack and ties them to complete the work. The drawback of this method is that the size of boxes that can be packaged and bundled manually is limited, and the packaging speed is also limited. This results in low work efficiency and accuracy, thus reducing work efficiency. The reliability of the packed stacks is insufficient, and the boxes are prone to scattering during transportation.

[0039] Based on this, an automated and highly efficient packaging system and method for boxed goods are provided. (See also...) Figure 1 , Figure 1A schematic diagram of the initial state structure of a packaging system 1 according to an embodiment of this application is shown. The packaging system 1 provided in this embodiment includes a support device 100 and a conveying device 200. The support device 100 includes a worktable 110 and a support bracket for supporting the worktable 110. The worktable 110 has a working plane 111, on which a working area for packaging box-shaped items is provided. The conveying device 200 is drivenly connected to the support bracket and located above the working plane 111. The conveying device 200 is used to pick up and convey corner protectors 2. At least a portion of the corner protector 2 being picked up is located below the working plane 111. Before the conveying device 200 conveys the corner protector 2 to the working area, the portion of the corner protector 2 located below the working plane 111 is bent by the worktable 110 to match the corner shape of the box-shaped item 3.

[0040] The aforementioned packaging system 1, by setting up a conveyor device 200, automatically picks up and transports the corner protectors 2 to the work area to package the box-shaped items 3, thereby improving the work efficiency of the packaging process. At the same time, through the cooperation of the conveyor device 200 and the worktable 110, when picking up or transporting the corner protectors 2, the corner protectors are bent into a shape that matches the corners of the box-shaped items 3 by taking advantage of the difference in their positions. The process of picking up, bending and packaging is seamless and the structure is simple, which improves efficiency without increasing the overall cost.

[0041] Specifically, such as Figure 2 (1) Figure 4 As shown in (1), before the conveying device 200 picks up the corner protector 2, a portion of the corner protector 2 is located below the working plane 111; or, the conveying device 200 picks up the corner protector 2 to a designated position, at which point a portion of the corner protector 2 is located below the working plane 111. Figure 2 (2) Figure 4 As shown in (2), the corner protector 2 is bent away from the work area. Before being bent, the corner protector 2 can be straight or "1" shaped. After being bent for the first time by the conveying device 200, the corner protector 2 forms an "L" shape. For the "L" shaped or arc-shaped corner protector 2, at least one edge of the box-shaped object 3 can be protected. For the "K" shaped corner protector 2, at least two edges of the box-shaped object 3 can be protected. The position of the conveying device 200 relative to the working plane 111 is adjustable so that the included angle at the bend of the "L" shaped corner protector 2 after bending is consistent with the angle of the edge of the box-shaped object 3 that needs to be packaged.

[0042] Furthermore, the corner protector 2 includes a first bent section 22 and a middle section 21. Before being removed, the first bent section 22 is parallel to the middle section 21. After being bent by the working plane 111, the first bent section 22 is parallel to the working plane 111, and the middle section 21 intersects (especially perpendicularly) the working plane 111.

[0043] In one embodiment, the conveying device 200 is capable of moving relative to the worktable 110 along a first direction X to the work area; the conveying device 200 includes a picking component 210 and a rotating component 220, the picking component 210 is used to fix the edge corner piece 2, and the rotating component 220 is used to drive the picking component 210 and the edge corner piece 2 to rotate around a second direction, the first direction X being parallel to the work plane 111, and the second direction Y being perpendicular to the work plane 111.

[0044] Specifically, such as Figure 2 (3) Figure 4 (3) As shown, the picking component 210 is mounted on the rotating component 220, which drives the picking component 210 to rotate around the second direction Y. The picking component 210 includes a suction cup 211 and a telescopic cylinder 212. The suction cup 211 is used to pick up the corner protector 2, and the telescopic cylinder 212 is connected to the suction cup 211 to adjust the position of the suction cup 211 so that it extends or retracts relative to the rotating component 220. At least two suction cups 211 are provided, which are spaced apart on the rotating component 220 to pick up both ends of the corner protector 2 respectively. The position of the two suction cups 211 is adjusted by the telescopic cylinder 212 to adjust the tilt angle of the corner protector 2. Since the position of the working plane 111 is fixed, the bending angle of the corner protector 2 during the first bend can be adjusted. Furthermore, the telescopic cylinder 212 is provided with an air passage to provide suction for the suction cup 211 to pick up the corner protector.

[0045] In one embodiment, the packaging system 1 further includes a storage component 300 for storing corner protectors 2, the outlet of the storage component 300 being located on one side of the workbench 110; the storage component 300 includes a feeding track 210 and a pusher 320, the corner protectors 2 being disposed on the feeding track 210, the feeding track 210 being inclined relative to the work plane 111, the pusher 320 abutting against the side of the corner protector 2 away from the outlet, and the pusher 320 being slidably connected to the feeding track 210.

[0046] Specifically, the pusher 320 is located at the end of the feeding track 210 away from the worktable and has a certain weight. It tends to move towards the worktable on the inclined feeding track 210. When there is no gap between the corner guards 2 and between the corner guards 2 and the outlet, the pusher 320 does not slide. When the corner guards 2 are removed and a gap is created, the pusher 320 moves and squeezes the corner guards 2, causing the corner guards 2 to move closer to each other and closer to the outlet.

[0047] Storage components 300 are located on opposite sides of the workbench 110 along the first direction X, with corner protectors 2 provided on each side. The work area is located in the middle of the workbench 110. Since the corner protectors 2, which are bent using the workbench 110, are bent away from the work area, the rotating component 220 is used to rotate the pick-up component 210 and the pick-up corner protector 2 so that the bent part faces the direction in which the box-shaped object 3 needs to be placed, i.e., towards the center of the work area. In this embodiment, the stored corner protectors 2 are located on both sides. After the first bend, the rotating component 220 rotates the bent corner protector 2 180° around the second direction Y, so that the corner protectors 2 on both sides are positioned opposite each other.

[0048] It is understood that the storage component 300 is at least one, and the rotation component 220 can also cause the retrieval component 210 to rotate around a direction perpendicular to the second direction Y and the first direction X.

[0049] In one embodiment, the packaging system 1 further includes a drive assembly 400, which includes a guide rod 420 slidably connected to the support and a drive motor 410. The conveying device 200 is connected to the guide rod 420, and the drive unit drives the guide rod 420 to move along a first direction X, which is parallel to the working plane 111.

[0050] Specifically, the picking component 210 and the rotating component 220 are mounted on the guide rod 420. The rotating component 220 is sleeved on the guide rod 420 and rotatably connected to it. In some cases, the rotating component 220 can also be slidably connected to the guide rod 420. The rotating component 220 can move relative to the guide rod 420 along the second direction Y. The guide rod 420 is slidably connected to the bracket. Driven by the drive motor 410, the guide rod 420 moves along the first direction X to the vicinity of the working area, so that the corner guard 2 after the first bend is located at the designated position in the working area.

[0051] In one embodiment, the support includes a support column 120 and a gantry frame 130. The gantry frame 130 is spaced apart from and connected to the working plane 111 between adjacent support columns 120. A lead screw 430 is provided inside the gantry frame 130 along the first direction X. One end of the guide rod 420 is connected to the lead screw 430. The drive motor 410 drives the lead screw 430 to rotate. A limiting member 440 is provided on the lead screw 430, and the limiting member 440 is positioned corresponding to the working area.

[0052] Specifically, at least two support columns 120 are provided, which support and connect to both sides of the worktable 110 respectively, extending from the top to the bottom of the worktable 110, and providing clearance for the operation of the storage component 300 and the conveying device 200. The gantry frame 130 extends substantially along the first direction X and connects to the ends of the support columns 120 on both sides away from the worktable 110. The gantry frame 130 and the support columns 120 together form a gantry frame structure.

[0053] In this embodiment, two conveying devices 200 are provided. A drive motor 410 is mounted on the gantry frame 130. The number of lead screws 430 corresponds to the number of conveying devices 200. The lead screws 430 are respectively connected to both sides of the drive motor 410. When there is only one drive motor 410, the lead screws 430 on both sides move in opposite directions, driving the two conveying devices 200 to move in opposite directions or relative to each other. Multiple limiting members 440 are provided, each corresponding to a position in the working area, allowing the conveying device 200 driven by the guide rod 420 to accurately stop at the required position, or allowing some of the limiting members 440 to correspond to suitable retrieval positions.

[0054] In one embodiment, the conveying device 200 includes a folding assembly 230. After the conveying device 200 conveys the corner protector 2 to the working area and the box-shaped object 3 is placed on the corner protector 2, the folding assembly 230 is used to bend the portion of the corner protector 2 extending beyond the box-shaped object 3 toward the box-shaped object 3. The folding assembly 230 includes a power unit 232 and a folding arm 231. The folding arm 231 is spaced apart from the worktable 110. The power unit 232 is used to drive the folding arm 231 to rotate relative to the working plane 111 and / or move along a first direction X to bend the portion of the corner protector 2 extending beyond the box-shaped object 3.

[0055] Specifically, such as Figure 3As shown, the hemming component 230 is provided on the guide rod 420. The hemming component 230 can be oriented towards the working area or can be drivingly connected to the rotating component 220 and rotate therewith. After the corner protector 2 after the first bending moves along the first direction X to the working area under the drive of the conveying device 200, the picking component 210 does not release the corner protector 2, and the box-shaped object 3 to be packaged is placed on the first bending section 22 of the corner protector 2. The part of the corner protector 2 that exceeds the top surface of the box-shaped object 3 is secondarily bent by the hemming component 230.

[0056] The conveying device 200 further includes a mounting post 233 disposed at an interval from the guide rod 420. The mounting post 233 is arranged along the second direction Y. The mounting post 233 is used for mounting the picking component 210 and the hemming arm 231. The rotating component 220 directly drives the mounting post 233 to rotate, thereby driving the picking component 210 and the hemming arm 231 to rotate. The power machine 232 is disposed on the mounting post 23. The middle part of the hemming arm 231 is movably connected and / or slidably connected to the mounting post 233. One end of the hemming arm 231 is drivingly connected to the power machine 232, and the other end is used for hemming. The position where the middle part of the hemming arm 231 is connected to the mounting post 233 serves as a fulcrum. The power machine 232 drives the hemming arm 231 to rotate relative to the working plane 111 about this fulcrum to complete the secondary bending of the corner protector 2 towards the top of the box-shaped object 3. The middle part of the hemming arm 231 can also slide relative to the mounting post 233 along the first direction X (including a direction having an included angle with the first direction X) to make the corner protector 2 fit more closely to the top surface of the box-shaped object 3. A plurality of connection positions are provided on the mounting post 233. The middle part of the hemming arm 231 can be connected to different connection positions according to the size of the box-shaped object 3.

[0057] As Figure 3 As shown in (2), the corner protector 2 is secondarily bent (hemmed) in the direction towards the working area. The cross-sectional shape of the corner protector 2 before being bent can be an "L" shape. After the corner protector 2 is secondarily bent by the conveying device 200, a "U" shape is correspondingly formed, or an "O" shape symmetrically formed by the bending of the corner protectors 2 on both sides. For the corner protector 2 with a "U" shape formed on one side, at least two edges of the box-shaped object 3 can be protected. For the corner protectors 2 with an "O" shape formed oppositely on both sides, at least four edges of the box-shaped object 3 can be protected. The corner protector 2 further includes a second bending section 23. The middle section 21 is located between the first bending section 22 and the second bending section 23. The second bending section 23 is the part that exceeds the top surface of the box-shaped object 3 after the box-shaped object 3 is placed on the first bending section 22.

[0058] In one embodiment, the working plane 111 is recessed with a strapping groove (not shown in the figure) for the strapping strap to pass through. Specifically, the strapping groove is provided through the center of the working area, and multiple strapping grooves of different sizes can be provided. The strapping strap passes through the strapping groove below the box-shaped item 3 with the corner protectors 2 packaged for strapping, without lifting the stacked box-shaped items 3 and without the need for a lifting device.

[0059] This application also provides a packaging method for a box-shaped item 3, employing the packaging system 1 described above. The packaging method includes the following steps:

[0060] S100, Take the corner protector 2, at least a portion of the corner protector 2 being taken is located below the working plane 111;

[0061] S200. Before the corner protector 2 is conveyed to the work area, the portion of the corner protector 2 located below the work plane 111 is bent by the workbench 110 to match the corner shape of the box-shaped object 3.

[0062] S300, the bent corner protector 2 moves to the working area and the box-shaped object 3 is placed on the corner protector 2.

[0063] In one embodiment, after the step of placing the box-shaped object 3 on the corner protector 2, the method further includes:

[0064] S400, bend the portion of the corner protector 2 that extends beyond the box-shaped object 3 toward the box-shaped object 3;

[0065] And / or, S500, the box-shaped object 3 and the corner protector paper are bundled together by passing a strapping tape between the box-shaped object 3 and the working plane 111.

[0066] Specifically, in step S200, when the corner protector 2 is taken from the storage component 300 to the removal component (or the removal component 210 takes the corner protector 2 and rotates it), the part of the corner protector 2 located below the working plane 111 is bent by the worktable 110 for the first time.

[0067] In step S300, the corner protector 2 after the first bend is rotated and moved along the first direction X to reach the designated position in the work area. At least two sides of the box-shaped object 3 are placed on the corner protector 2 against the bent corner protector 2, and S400 and / or S500 are executed.
