Description

Technical Field

[0001] This application relates to warehousing and logistics technology, and more particularly to a folding pallet. Background Technology

[0002] Pallets are loading platforms used for assembling, stacking, handling, and transporting goods. They belong to a category of warehousing and logistics products. Among them, foldable paper pallets have good lightweight properties and ease of use, and are widely used in various food and pharmaceutical industries.

[0003] Existing pallets are formed by folding cut pieces. The cut pieces generally include a base plate and various side plates. Adjacent side plates are folded and glued together with the base plate to form the cavity of the pallet.

[0004] Currently, suppliers typically stack multiple pallets for transportation. If pre-folded and glued pre-formed pallets are transported, it wastes transportation space and can easily cause product quality to be affected by mutual compression and deformation. If unformed cut pieces are transported, the receiving party needs to assemble them themselves after receiving the goods, which wastes time and affects the normal work schedule. Utility Model Content

[0005] This application provides a folding pallet to solve the technical problem in the related art that pallets are easily wasted when they are folded into shape in advance for transportation.

[0006] This application provides a foldable tray, including:

[0007] The cut piece body includes a base plate, two first side plates and two second side plates, with the first side plates and the second side plates arranged alternately around the base plate.

[0008] A bending plate is provided at each of the opposite ends of the first side plate, and a preset crease is provided between the bending plate and the first side plate. The bending plate is configured to fold relative to the first side plate along the preset crease.

[0009] The second side plate includes a plate body folded toward the bottom plate and a connecting part folded away from the bottom plate, the connecting part being used to connect with the folded bent plate;

[0010] Each of the second side plates has at least one cutout portion, which is configured to engage with at least a portion of the bent plate so that the inserted bent plate prevents the plate body from tilting inward toward the bottom plate.

[0011] In some possible implementations, the second side plate is arranged along the width direction of the base plate, and the cutout portion is a strip-shaped opening extending along the width direction of the plate body.

[0012] In some possible implementations, a first crease is provided between the first side plate and the bottom plate, and the first side plate is folded along the first crease;

[0013] The second side plate and the bottom plate have a second crease, and the second side plate is folded along the second crease; the first side plate and the second side plate are configured to form a cavity together with the bottom plate.

[0014] In some possible implementations, the preset crease and the second crease are located on the same straight line;

[0015] A third crease is provided between the connecting part and the plate body. The first crease and the second crease have an intersection point. One end of the third crease extends to the intersection point, and the other end extends to the outer edge of the second side plate away from the bottom plate.

[0016] In some possible implementations, the angle between the third crease and the second crease is 40°-50°.

[0017] In some possible implementations, the length of the bent plate is greater than the width of the adjacent second side plate along the length direction of the base plate.

[0018] In some possible implementations, the bent plate has an adjacent edge on the side facing the adjacent second side plate, the adjacent edge gradually sloping outward in a direction away from the first side plate.

[0019] In some possible implementations, the connecting portion and the bending plate are attached by Velcro.

[0020] In some possible implementations, each of the second side panels has two spaced-apart cutouts, each cutout being used to insert into at least a portion of a bent plate on the adjacent first side panel.

[0021] In some possible implementations, a retaining groove is provided on each of the opposite sides of the bent plate. The retaining groove is used to engage with the hollowed-out portion to prevent the bent plate from detaching from the hollowed-out portion.

[0022] The folding tray provided in this application has a base plate, a first side plate, and a second side plate on the cut piece body, all of which can be a single planar shape. The first side plate is bent along a preset crease to form a pre-formed tray shape. Therefore, the cut pieces can be directly stacked during transportation, reducing the space occupied.

[0023] The hollowed-out section on the second side plate engages with at least part of the bent plate, causing the bent plate to tilt inward toward the floor. The bent plate and the second side plate interlock to form an "L"-shaped physical self-locking mechanism. This design is easy to operate, requires no other tools, and can be quickly assembled and used.

[0024] In addition, the lateral force on the pre-formed pallet is transmitted to the bending plate through the edge of the cutout. The vertical force on the pallet is distributed to the bottom plate by the bending plate and the second side plate. When the bending plate, which is bent by the pre-set creases, tilts inward, it is blocked by the interlocking action of the cutout and the bending plate. The pallet has a good forming state and resistance to deformation, making it easy to use and load items. Attached Figure Description

[0034] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0035] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0036] As described in the background section, existing pallets are formed by folding cut pieces. The cut pieces generally include a base plate and various side plates, which, together with the base plate, form the cavity of the pallet after being folded and glued.

[0037] Currently, suppliers typically stack multiple pallets for transportation. If pre-folded and glued pre-formed pallets are transported, it wastes transportation space and can easily cause product quality to be affected by mutual compression and deformation. If unformed cut pieces are transported, the receiving party needs to assemble them themselves after receiving the goods, which wastes time and affects the normal work schedule.

[0038] Based on the above description, one or more embodiments of this application provide a foldable tray. The base plate, first side plate, and second side plate on the cut piece body can all be a single planar shape. The first side plate is bent along a preset crease to form a pre-formed tray shape. Therefore, the cut pieces can be directly stacked during transportation, reducing space occupation. Utilizing the hollow portion provided on the second side plate, the hollow portion is inserted and engaged with at least part of the bent plate, causing the inserted bent plate to tilt inward toward the floor side. The bent plate and the second side plate are inserted to form an "L"-shaped physical self-locking mechanism, which is convenient to operate, can be quickly assembled without other tools, and is easy to use.

[0039] The folding pallet solution of this application is described below with reference to the accompanying drawings.

[0040] like Figure 1 and Figure 2 As shown, the folding tray of this application embodiment includes a cut piece body 100, the cut piece body 100 includes a base plate 110, two first side plates 120 and two second side plates 130, the first side plates 120 and the second side plates 130 are arranged alternately around the base plate 110.

[0041] A bending plate 121 is provided at each of the opposite ends of the first side plate 120. A preset crease 122 is provided between the bending plate 121 and the first side plate 120. The bending plate 121 is configured to fold relative to the first side plate 120 along the preset crease 122.

[0042] The second side plate 130 includes a plate body 131 folded toward the bottom plate 110 and a connecting portion 132 folded away from the bottom plate 110. The connecting portion 132 is used to connect with the folded bent plate 121. Each second side plate 130 is provided with at least one hollow portion 133. The hollow portion 133 is configured to engage with at least a portion of the bent plate 121 so that the inserted bent plate 121 prevents the plate body 131 from tilting inward toward the bottom plate 110.

[0043] As can be seen from the above description, the folding tray of this application embodiment has a single planar structure for the bottom plate 110, the first side plate 120, and the second side plate 130 of the cut piece body 100. Multiple cut piece bodies 100 can be directly stacked during transportation, which is convenient for stacking and compression and saves transportation space. When needed, the first side plate 120 and the second side plate 130 are directly pulled up, and the bent plate 121 is inserted into the hollow part 133 of the second side plate 130. The folded plate and the second side plate 130 are connected to form an "L"-shaped physical self-locking. The blocking plate body 131 tilts inward toward the floor. The assembly process is convenient and simple, and a stable tray structure can be assembled without other auxiliary tools. It is easy to use and has high assembly efficiency.

[0044] In this embodiment, the cut piece body 100 can be made of a material with certain bending and deformation properties, such as hard kraft paperboard, corrugated cardboard or natural bamboo fiber laminate. Of course, in some embodiments, the cut piece body 100 can also be made of solid wood, plywood or hard plastic board. When using materials that are not easily deformed and folded, such as solid wood or hard plastic board, the fold area that needs to be folded can be thinned or additional deformable connecting parts 132 can be made, as long as it can be bent along the fold to form a tray.

[0045] like Figure 2 As shown in the embodiment of this application, a first crease 111 is provided between the first side plate 120 and the bottom plate 110, and the first side plate 120 is folded along the first crease 111; a second crease 112 is provided between the second side plate 130 and the bottom plate 110, and the second side plate 130 is folded along the second crease 112; the first side plate 120 and the second side plate 130 are configured to form a cavity together with the bottom plate 110.

[0046] The first crease 111 and the second crease 112 mentioned above can adopt crease designs in related technologies. For example, the first crease 111 and the second crease 112 can be pre-pressed creases, or easily deformable lines with intermittent hollow openings. Pre-treatment can be performed in each crease area, and a 0.1 mm polyurethane coating can be impregnated in the crease area of ​​the cut piece body 100 to enhance the stability of multiple folds.

[0047] The first side plate 120 is folded 90° along the first crease 111, and the second side plate 130 is folded 90° along the second crease 112. The first side plate 120, the second side plate 130, and the bottom plate 110 together form a rectangular cavity. Both the first side plate 120 and the second side plate 130 are folded toward the inside of the bottom plate 110. Therefore, the folded second side plate 130 tends to tilt inward toward the floor. The hollow part 133 of the second side plate 130 is inserted and engaged with the bent plate 121 at the end of the first side plate 120 to jointly prevent the second side plate 130 from tilting inward toward the bottom plate 110.

[0048] Furthermore, the preset crease 122 and the second crease 112 are located on the same straight line.

[0049] A third crease 134 is provided between the connecting part 132 and the plate body 131. The first crease 111 and the second crease 112 have an intersection point 113. One end of the third crease 134 extends to the intersection point 113, and the other end extends to the outer edge of the second side plate 130 away from the bottom plate 110.

[0050] It should be noted that the inner and outer sides in the embodiments of this application are relative to the relative positions during the preforming of the pallet. When the first side plate 120 and the second side plate 130 surround the bottom plate 110, the side of the first side plate 120 away from the bottom plate 110 is the outer side, and the side of the first side plate 120 facing the floor is the inner side.

[0051] The connecting part 132 mentioned above is a triangular area on the second side plate 130. The connecting part 132 is folded along the third crease 134 toward the floor, and the bending plate 121 is folded along the preset crease 122 toward the floor. The connecting part 132 and the bending plate 121 are bonded together to initially form a pre-formed tray frame. At this time, since the connecting part 132 and the bending plate 121 are bonded after folding, the second side plate 130 will tend to tilt inward toward the floor due to the movement of the bending plate 121. The bending plate 121 is inserted into the hollow part 133 to form a support, which prevents the second side plate 130 from tilting inward toward the floor.

[0052] This also shows that the triangular area of ​​the connecting part 132 can cover a large bonding area while taking into account the folding strength, ensuring that the connection between the connecting part 132 and the bending plate 121 is tight.

[0053] The angle between the third crease 134 and the second crease 112 is 40°-50°. For example, the angle between the third crease 134 and the second crease 112 is 40°, or 45°, or 50°.

[0054] like Figure 2As shown, after the connecting part 132 is folded along the third crease 134, the included angle is related to the bonding area of ​​the connecting part 132 and the bending plate 121. Generally speaking, the larger the included angle between the third crease 134 and the second crease 112, the smaller the bonding area between the connecting part 132 and the bending plate 121, but the larger the portion of the bending plate 121 used to insert the hollow part 133. Therefore, the included angle between the third crease 134 and the second crease 112 can be flexibly set according to factors such as the actual width of the second side plate 130 and the length of the bending plate 121. This is not an absolute limitation in the embodiments of this application.

[0055] In some embodiments, the second side plate 130 is arranged along the width direction of the bottom plate 110, and the cutout portion 133 is a strip-shaped opening extending along the width direction of the plate body 131.

[0056] The aforementioned hollow portion 133 extends along the width direction of the plate body 131. The insertion direction of the bent plate 121 is perpendicular to the hollow portion 133. The width of the part of the bent plate 121 used to insert into the hollow portion 133 (i.e., the insertion end of the bent plate 121) is slightly smaller than the length of the strip opening. The insertion and cooperation of the bent plate 121 and the hollow portion 133 form the constraint of the first side plate 120 and the second side plate 130.

[0057] Along the length of the base plate 110, the length of the bent plate 121 is greater than the width of the adjacent second side plate 130.

[0058] like Figure 1 As shown, the base plate 110 is a rectangular plate. The length direction of the base plate 110 is along the extension direction of the first crease 111, and the width direction of the base plate 110 is along the extension direction of the second crease 112.

[0059] The bent plate 121 is a plate that protrudes along the length of the first side plate 120. The length of the bent plate 121 is greater than the width of the adjacent second side plate 130. When the bent plate 121 is bonded to the connecting part 132 of the second side plate 130, the portion of the bent plate 121 that protrudes from the second side plate 130 is used to insert into the hollow part 133 to form a stable connection, thus preventing the second side plate 130 from tilting inward toward the floor due to folding.

[0060] As an alternative implementation, the bent plate 121 has an adjacent edge 123 on the side facing the adjacent second side plate 130, and the adjacent edge 123 gradually slopes outward in the direction away from the first side plate 120.

[0061] After the bent plate 121 is folded along the preset crease 122, it is bonded to the connecting part 132 folded along the third crease 134. The adjacent edge 123 can form a clearance space between the bent plate 121 and the second side plate 130. When the connecting part 132 is a triangular area, the part of the bent plate 121 corresponding to the clearance space is not actually bonded to the connecting part 132, but is directly stacked on the connecting part 132, resulting in a waste of the bent plate 121. Therefore, by setting the adjacent edge 123, the insufficient bonding between the bent plate 121 and the connecting part 132 can be avoided.

[0062] In addition, due to the adjacent edge 123, the insertion end of the bent plate 121 forms a pointed tip that gradually tapers outwards, making it easier for the insertion end of the bent plate 121 to be inserted into the hollow part 133, which facilitates assembly and operation by the workers and helps to speed up the assembly efficiency.

[0063] like Figure 3 As shown, in some embodiments, a backstop groove 124 is provided on each of the opposite sides of the bending plate 121. The backstop groove 124 is used to engage with the hollow part 133 to prevent the bending plate 121 from disengaging from the hollow part 133.

[0064] The aforementioned anti-retraction groove 124 is provided on the insertion end of the bent plate 121. Along the insertion direction of the bent plate 121 toward the hollow part 133, after the insertion end of the bent plate 121 is inserted into the hollow part 133, the anti-retraction groove 124 engages with the hollow part 133 of the second side plate 130, preventing the bent plate 121 from disengaging from the hollow part 133, thereby forming a stable connection between the bent plate 121 and the second side plate 130.

[0065] Of course, as an alternative implementation, other structures can also be provided on the bent plate 121 to prevent it from detaching from the cutout 133. For example, the part of the bent plate 121 inserted into the cutout 133 is also folded relative to the second side plate 130, and the folding deformation is used to prevent the bent plate 121 from detaching from the cutout 133.

[0066] In some embodiments, the connecting portion 132 and the bending plate 121 are connected by Velcro.

[0067] For example, both the back of the male and female sides of the Velcro are coated with adhesive. The back of the male side is directly bonded to the connecting part 132 with the adhesive, and the back of the female side is bonded to the bending plate 121 with the adhesive. The bending plate 121 is folded along the preset crease 122, and the connecting part 132 is folded along the third crease 134. The male and female sides are bonded together to form an adhesive bond between the bending plate 121 and the connecting part 132.

[0068] The bending plate 121 and the connecting part 132 are connected by Velcro, which allows the cut piece body 100 to be quickly assembled into a tray. The formed tray can also be disassembled and restored to a flat plate shape, making the switching of the folding tray state more convenient. It can be reused and flexibly adapted to various transportation and use scenarios.

[0069] It should be noted that in the embodiments of this application, each second side plate 130 is provided with two spaced-apart cutouts 133, and each cutout 133 is used to be inserted into at least a portion of the bent plate 121 on the adjacent first side plate 120.

[0070] The first side plate 120 is provided with a bent plate 121 at each of its opposite ends. Each second side plate 130 is provided with two hollow parts 133 and two connecting parts 132. The connecting parts 132 on the second side plate 130 are connected to the bent plates 121 one by one. Thus, the first side plate 120 and the two adjacent second side plates 130 are bonded together by the bent plates 121 and the connecting parts 132, and the bent plates 121 are inserted into the hollow parts 133 of the second side plate 130.

[0071] The two first side panels 120 of this application are symmetrically arranged relative to the bottom plate 110, and the two second side panels 130 are symmetrically arranged relative to the bottom plate 110. After the first side panel 120 is folded along the first crease 111 and the second side panel 130 is folded along the second crease 112, a rectangular frame cavity is formed. In some alternative embodiments, the dimensions of the first side panel 120 and the second side panel 130 can also be adjusted and varied accordingly for folding trays of different sizes.

[0072] The foldable pallet of this application embodiment can be in the transport state as follows: Figure 1 The diagram shows the fully unfolded flat, plate-shaped cut piece body 100.

[0073] Or such as Figure 2 As shown, the bending plate 121 is folded along the preset crease 122, the second side plate 130 is folded through the second crease 112, and the connecting part 132 on the second side plate 130 is folded along the third crease 134. The folded bending plate 121 and the connecting part 132 are first glued together with Velcro. However, after the glued bending plate 121 and the connecting part 132 are both in a folded state, the first side plate 120 is not folded through the first crease 111. In this state, the cut piece body 100 is also a whole plate, which is convenient for transportation and stacking.

[0074] When it is necessary to assemble a molded pallet, Figure 2In the cut piece body 100, the first side plate 120 is folded along the first crease 111, and the second side plate 130 is folded along the second crease 112. The first side plate 120 and the second side plate 130 are pulled up as a whole. Then, the extra parts of the bent plates 121 at both ends of the first side plate 120 are inserted into the hollow part 133 of the adjacent second side plate 130. The bent plates 121 support and form a complete tray frame, which is convenient for holding items.
