Description

Technical Field

[0001] This invention relates to a pallet, and more particularly to a composite pallet. Background Technology

[0002] During transportation, to prevent electronic products (such as display panels or LCD glass) from being damaged by collisions, manufacturers typically stack multiple electronic products on a pallet to provide cushioning protection and increase the number of electronic products that can be loaded.

[0003] However, as the number of electronic products stacked increases, the risk of friction or collision between multiple electronic products also increases, and the thickness of the bottom wall of the tray also needs to be increased accordingly to support the weight of multiple electronic products, resulting in increased manufacturing costs of the tray and reduced product loading rate. Summary of the Invention

[0004] In view of the above, in one embodiment, a composite pallet is provided, comprising a pallet body and an external support member. The pallet body includes a support plate and multiple sidewalls protruding from the support plate, the multiple sidewalls and the support plate together forming a receiving groove, and the receiving groove having an opening. The external support member includes a support plate and multiple connecting members, the support plate being located within the receiving groove and dividing the receiving groove into an inner space and an outer space, the inner space being located between the support plate and the support plate, and the outer space being located between the opening and the support plate, the multiple connecting members being connected around the support plate and respectively connected to the multiple sidewalls, and the thickness of the support plate being less than the thickness of the support plate.

[0005] In some embodiments, the inner space accommodates a first carrier, the outer space accommodates a second carrier, the first carrier rests against a support plate, and the second carrier rests against a support plate.

[0006] In some embodiments, there is a gap between the first carrier and the support plate.

[0007] In some embodiments, each of the aforementioned sidewalls extends into the receiving recess as a retaining wall, and the first carrier and the second carrier are confined between the plurality of retaining walls.

[0008] In some embodiments, each of the aforementioned sidewalls has a snap-fit ​​groove, and each assembly is snapped into the snap-fit ​​groove.

[0009] In some embodiments, the above-mentioned fastener has a groove wall, and each component is a U-shaped plate having a first side plate, a second side plate and a connecting plate. The connecting plate is connected to the end of the first side plate and the second side plate away from the support plate, and a slot is formed between the first side plate, the second side plate and the connecting plate, and the groove wall is inserted into the slot.

[0010] In some embodiments, the first side plate and the connecting plate have a first included angle, and the second side plate and the connecting plate have a second included angle, wherein at least one of the first included angle and the second included angle is less than 90 degrees.

[0011] In some embodiments, the composite pallet further includes a cover stacked on the pallet body, the cover having a positioning post inserted into a slot of one of the plurality of sidewalls, and the positioning post pressing against the portion of the assembly located in the slot.

[0012] In some embodiments, the first side plate of the above-mentioned assembly is located inside the snap groove, and the positioning post has a side side that abuts against the first side plate.

[0013] In some embodiments, the bottom end of the first side plate is connected to an extension plate, and the positioning post has a bottom surface that presses against the extension plate.

[0014] In some embodiments, the cover is another tray body.

[0015] In some embodiments, the material of the external support member is different from the material of the tray body.

[0016] In some embodiments, the tensile strength of the external support member is greater than the tensile strength of the pallet body.

[0017] In some embodiments, the material density of the external support member is greater than the material density of the tray body.

[0018] In summary, the composite pallet according to the embodiments of the present invention divides the accommodating groove into an inner space and an outer space by a support plate of an external support member, and the thickness of the support plate is less than the thickness of the bearing plate of the pallet body. This allows the inner space and the outer space to accommodate loads respectively, with the loads in the inner space resting on the bearing plate and the loads in the outer space resting on the support plate. Therefore, the thickness of the pallet body does not need to be increased, thereby reducing manufacturing costs and increasing the loading rate of the product. In addition, after the composite pallet is dropped, the gravitational acceleration borne by the loads inside can also be effectively reduced, thereby significantly reducing the probability of damage to the loads.

[0065] Figure 1 This is a perspective view of an embodiment of the composite tray of the present invention. Figure 2 This is an exploded perspective view of an embodiment of the composite tray of the present invention. Figure 3 This is a cross-sectional view of an embodiment of the composite tray of the present invention. Figure 1 and Figure 2 As shown, the composite tray 1 of this embodiment includes a tray body 10 and an external support member 20. The composite tray 1 is used to carry various items. For example, the composite tray 1 can be used to carry sheet-like electronic products (such as display panels or liquid crystal glass), but this is not a limitation.

[0066] like Figures 1 to 3 As shown, the pallet body 10 includes a support plate 11 and a plurality of side walls 12, which protrude from the surface of the support plate 11 and together with the support plate 11 form at least one receiving groove 15. For example Figure 2As shown, in this embodiment, multiple sidewalls 12 and the support plate 11 together form two receiving grooves 15. Each receiving groove 15 has an opening 151, and the carrier (e.g., a display panel or liquid crystal glass) can be placed into the receiving groove 15 through the opening 151. However, the above embodiment is only an example, and the number of sidewalls 12 and the number of receiving grooves 15 of the tray body 10 can be adjusted according to actual product requirements.

[0067] In some embodiments, the support plate 11 of the pallet body 10 and the plurality of side walls 12 may be integrally formed, and the material of the pallet body 10 may be a cushioning material to protect the load placed in the receiving groove 15. For example, the cushioning material may be a foamed material such as expanded polystyrene (EPS), expanded polypropylene (EPP), expanded polyethylene (EPE), or expanded ethylene polymer (EPO).

[0068] like Figures 1 to 3 As shown, the number of external support members 20 can correspond to the number of receiving grooves 15 in the pallet body 10, and the external support members 20 are used to assemble the receiving grooves 15 and multiple sidewalls 12 located around the receiving grooves 15. Taking one set of receiving grooves 15 and external support members 20 as an example, the external support member 20 includes a support plate 21 and multiple connecting members 25. The support plate 21 is located in the receiving groove 15 and divides the receiving groove 15 into an inner space 16 and an outer space 17. The inner space 16 is located between the support plate 21 and the bearing plate 11, and the outer space 17 is located between the opening 151 of the receiving groove 15 and the support plate 21. The multiple connecting members 25 are connected around the support plate 21 and can be detachably assembled with multiple sidewalls 12 around the receiving groove 15.

[0069] In some embodiments, each side of the support plate 21 may be connected to at least one assembly 25, for example Figure 2 As shown, in this embodiment, each side of the support plate 21 is connected to two or more connecting parts 25, and the multiple connecting parts 25 are spaced apart from each other, so that the external support 20 can be more stable and less prone to shaking or displacement after being connected to multiple side walls 12.

[0070] like Figure 3As shown, the thickness of the support plate 21 of the external support member 20 is less than the thickness of the bearing plate 11 of the pallet body 10, so as to reduce the space occupied by the support plate 21 in the receiving groove 15, allowing the receiving groove 15 to accommodate more or larger loads. In this embodiment, the bearing plate 11 has a bearing surface 111 and a bottom surface 112. The bearing surface 111 is used to contact and bear the loads housed in the inner space 16, and the bottom surface 112 is used to support objects outside the pallet body 10. The thickness of the bearing plate 11 can refer to the thickness between the bearing surface 111 and the bottom surface 112. The support plate 21 has a support surface 211 and a bottom surface 212. The support surface 211 is used to contact and bear the loads housed in the outer space 17, and the bottom surface 212 is the surface of the support plate 21 closest to the bearing plate 11. The thickness of the support plate 21 can refer to the thickness between the support surface 211 and the bottom surface 212.

[0071] However, the above embodiments are merely examples. In some embodiments, the thickness of the bearing plate 11 may also refer to the maximum thickness, minimum thickness, or average thickness of the bearing plate 11, and the thickness of the support plate 21 may also refer to the maximum thickness, minimum thickness, or average thickness of the support plate 21.

[0072] In some embodiments, the support plate 21 of the external support member 20 and the plurality of connecting parts 25 may be integrally formed, and the material of the external support member 20 may be different from the material of the pallet body 10. In addition, the strength (e.g., tensile strength, compressive strength, or bending strength) of the external support member 20 may be greater than the strength (e.g., tensile strength, compressive strength, or bending strength) of the pallet body 10, or the material density of the external support member 20 may be greater than the material density of the pallet body 10, so that the external support member 20 can withstand greater pressure relative to the pallet body 10 without easily breaking, deforming, or being damaged. Therefore, even if the thickness of the support plate 21 of the external support member 20 is less than the thickness of the bearing plate 11 of the pallet body 10, the support plate 21 can still provide good load-bearing capacity.

[0073] Continuing from the above, for example, the tray body 10 can be made of foam material, wherein the density of the foam material is generally between 0.02 and 0.7 g / cm³. 3 The external support component 20 can be made of metal or plastic, wherein the metal material can be iron, aluminum, or steel, all with a density greater than 2 g / cm³. 3 The material used, specifically the plastic material, can be PET (density approximately 1.3–1.4 g / cm³). 3 ABS material (density approximately 1.06 g / cm³) 3 ) or PC material (density approximately 1.2 g / cm³) 3 This makes the strength and material density of the external support 20 greater than those of the pallet body 10.

[0074] Thus, the composite pallet 1 of this embodiment of the invention divides the accommodating groove 15 into an inner space 16 and an outer space 17 through an external support member 20, so that the inner space 16 and the outer space 17 can respectively accommodate the load. The load in the inner space 16 rests on the support plate 11, that is, the support plate 11 is used to support the load in the inner space 16, and the load in the outer space 17 rests on the support plate 21, that is, the support plate 21 is used to support the load in the outer space 17. Therefore, the support plate 11 does not need to bear the weight of all the loads on its own, so that the thickness of the support plate 11 does not need to be increased, thereby reducing manufacturing costs and increasing the loading rate of the product.

[0075] Specifically, such as Figure 4 As shown, where Figure 4 This is a cross-sectional view of the composite pallet carrying items according to the present invention. In this embodiment, the inner space 16 accommodates a first carrier 30, which is two stacked first panels 31. The first carrier 30 rests on the support plate 11. The outer space 17 accommodates a second carrier 40, which is two stacked second panels 41. The second carrier 40 rests on the support plate 21 of the external support member 20. There is a gap between the first carrier 30 and the support plate 21 in the inner space 16. Therefore, the first carrier 30 and the second carrier 40 are separated from each other and do not stack on each other, so that the weight of the first carrier 30 and the second carrier 40 is not all concentrated on the support plate 11 of the pallet body 10. Therefore, the thickness of the support plate 11 of the pallet body 10 does not need to be increased to allow the composite pallet 1 to accommodate multiple panels, thereby reducing the amount of material used and reducing manufacturing costs.

[0076] Additionally, please refer to Figure 4 and Figure 5 As shown, where Figure 5 This is a schematic diagram of the stacking of the composite pallet of the present invention. As mentioned above, since the thickness of the bearing plate 11 of the pallet body 10 does not need to be increased, the number of composite pallets 1 stacked can be increased accordingly during transportation or storage, thereby improving the product loading rate. In addition, since the first bearing 30 and the second bearing 40 in the receiving groove 15 are separated from each other and do not stack on top of each other, the gravitational acceleration borne by the bearings in the receiving groove 15 can be effectively reduced when the composite pallet 1 is dropped, thereby significantly reducing the probability of damage to the bearings.

[0077] For example Figure 2As shown, the support plate 21 of the external support member 20 may also have at least one reinforcing rib to further improve the structural strength (such as tensile strength, compressive strength, or bending strength) of the support plate 21 and thus have better load-bearing capacity. In this embodiment, the support plate 21 has a plurality of elongated first reinforcing ribs 213 and elongated second reinforcing ribs 214, wherein the plurality of first reinforcing ribs 213 are arranged in two rows, and the second reinforcing ribs 214 are located between the two rows of first reinforcing ribs 213, and the first extension direction of each first reinforcing rib 213 is different from the second extension direction of the second reinforcing rib 214 (where the first extension direction and the second extension direction are perpendicular to each other), so that the support plate 21 can be reinforced in different directions.

[0078] Figure 6 This is a top view of an embodiment of the composite tray of the present invention. Please refer to it. Figure 2 , Figure 4 and Figure 6 As shown, each sidewall 12 of the pallet body 10 extends at least one baffle 14 into the receiving groove 15, wherein the sidewall 12 and the baffle 14 are integrally formed. The first load 30 and the second load 40 are confined between the multiple baffles 14, achieving a buffering effect to prevent the first load 30 and the second load 40 from being impacted by external forces during transportation. In addition, in this embodiment, each sidewall 12 of the pallet body 10 extends with two or more baffles 14, and the multiple baffles 14 are spaced apart from each other, so that each side of the first load 30 and the second load 40 can be confined at multiple points to enhance the buffering effect.

[0079] In some embodiments, multiple connecting parts 25 of the external support 20 can be detachably connected to multiple side walls 12 of the tray body 10 by means of snapping, inserting, or clamping. For example, such as Figure 2 and Figure 3 As shown, in this embodiment, each sidewall 12 of the pallet body 10 has at least one fastening groove 13, wherein the number and position of the fastening grooves 13 correspond to the number and position of the plurality of connecting parts 25 of the external support member 20, and each connecting part 25 is fastened to each fastening groove 13, so that the external support member 20 is detachably connected to the pallet body 10.

[0080] Figure 7 This is a partially enlarged cross-sectional view of an embodiment of the composite tray of the present invention. Please refer to it. Figure 3 and Figure 7As shown, in this embodiment, each of the snap-fit ​​slots 13 of the pallet body 10 has a slot wall 131, and each of the connecting parts 25 of the external support member 20 is a U-shaped plate with a first side plate 251, a second side plate 252 and a connecting plate 253. The connecting plate 253 is connected to the end of the first side plate 251 and the second side plate 252 away from the bearing plate 11, so that a U-shaped slot 254 is formed between the first side plate 251, the second side plate 252 and the connecting plate 253. The slot wall 131 of each snap-fit ​​slot 13 is inserted into the slot 254 of each connecting part 25, so that each connecting part 25 is snapped into each snap-fit ​​slot 13.

[0081] For example Figure 7 As shown, the first side plate 251 of each component 25 of the external support member 20 has a first included angle A1 with the connecting plate 253, and the second side plate 252 has a second included angle A2 with the connecting plate 253. At least one of the first included angle A1 and the second included angle A2 is less than 90 degrees. After the groove wall 131 of each snap-fit ​​13 is inserted into the slot 254 of each component 25, the first side plate 251 and the second side plate 252 can clamp the groove wall 131 of each snap-fit ​​13, thereby achieving a stronger fixing effect. In this embodiment, the first included angle A1 and the second included angle A2 of each component 25 are both less than 90 degrees, and the distance D between the end of the first side plate 251 near the bearing plate 11 and the end of the second side plate 252 near the bearing plate 11 is smaller than the thickness of the groove wall 131 of each snap-fit ​​13, so as to increase the force of the first side plate 251 and the second side plate 252 clamping the groove wall 131 and further strengthen the fixing effect.

[0082] However, the above embodiments are merely examples. In some embodiments, the first included angle A1 between the first side plate 251 and the connecting plate 253 of each assembly 25 and the second included angle A2 between the second side plate 252 and the connecting plate 253 may both be 90 degrees.

[0083] Figure 8 This is an anatomical view of the multiple tray bodies of the composite tray of the present invention. Figure 9 This is a stacked cross-sectional view of multiple pallet bodies of the composite pallet of the present invention. (See image below.) Figure 8 and Figure 9As shown, the composite tray 1 also includes a cover, which is stacked on the tray body 10 to cover the opening 151 of the receiving groove 15 of the tray body 10. In this embodiment, the cover is the tray body 10a of another composite tray 1a. The bottom of the tray body 10a has at least one positioning post 101a, which is inserted into at least one snap-fit ​​groove 13 of a plurality of side walls 12. The portion of the connector 25 located in the snap-fit ​​groove 13 is further pressed by the positioning post 101a, so that the multiple composite trays 1,1a can be fixed to each other by the positioning post 101a after being stacked, thus avoiding easy separation. The connector 25 of the external support 20 is also pressed by the positioning post 101a, which strengthens the fixing effect between the external support 20 and the tray body 10.

[0084] Please check again Figure 8 and Figure 9 As shown, in this embodiment, the first side plate 251 of the assembly member 25 of the external support member 20 is located inside the fastening groove 13. The positioning post 101a of the tray body 10a has a side surface 102a, which presses against the first side plate 251, so that the first side plate 251 can be tightly against the groove wall 131 of the fastening groove 13 to enhance the positioning effect. Or, as Figure 10 As shown, where Figure 10 This is another stacked cross-sectional view of the composite pallet of the present invention, in another embodiment,

[0085] The bottom end of the first side plate 251 located in the groove 13 is integrally connected to an extension plate 255. The positioning post 101a has a bottom surface 103a, which presses against the extension plate 255, so that the first side plate 251 and the extension plate 255 can be pressed by the positioning post 101a at the same time to enhance the positioning effect.

[0086] In summary, according to the composite pallet 1 of the present invention, the accommodating groove 15 is divided into an inner space 16 and an outer space 17 by the support plate 21 of the external support member 20, and the thickness of the support plate 21 is less than the thickness of the bearing plate 11 of the pallet body 10, so that the inner space 16 and the outer space 17 can respectively accommodate the load, and the load in the inner space 16 rests on the bearing plate 11, while the load in the outer space 17 rests on the support plate 21. Therefore, the thickness of the pallet body 10 does not need to be increased, thereby reducing manufacturing costs and increasing the loading rate of the product. In addition, after the composite pallet 1 is dropped, the gravitational acceleration borne by the load inside can also be effectively reduced, thereby greatly reducing the probability of damage to the load.

[0087] Although the technical content of the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any modifications and refinements made by those skilled in the art without departing from the spirit of the present invention should be included within the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
