Description

Modular buffering pallet structure

Technical Field

The present invention relates to a pallet structure, and more particularly to a modular buffering pallet structure with buffering, fool-proof, and environmental protection functions.

Background

In the existing shipping and transportation schemes of heavy cabinets (such as complete cabinets), the common scheme is a combination scheme of buffering pallets and slope application. The buffer pallet is used as a transport tool and has two main performances of bearing and buffering, wherein the requirement of the bearing performance is that when a heavy cabinet is loaded, unloaded and transported, the buffer pallet has enough strength as a whole so as not to deform due to over-expected compression, thereby causing bearing failure and damage; on the other hand, the requirement of buffering is that the buffering pallet can absorb a part of the external vibration and impact energy received during loading, unloading or transportation, so as to protect the heavy cabinet body from being damaged.

A conventional buffering pallet structure is shown in fig. 1 and 2, which are a perspective view and a side view of a conventional buffering pallet PA1, respectively. As shown in the figure, the conventional buffer pallet PA1 comprises a bottom board PA11, a plurality of D buffer materials PA13 evenly disposed on the bottom board PA11, and an additional circuit board PA15 disposed on the plurality of buffer materials PA13, wherein the bottom board PA11 and the additional circuit board PA15 are usually made of wood materials, and the buffer material is Expanded Polyethylene (EPE), which is an elastic material capable of providing buffering and safety, and is fixedly combined with the upper and lower 2 wood boards (i.e., the bottom board PA11 and the additional circuit board PA15) by glue adhesion.

Generally, after the transportation of the conventional buffer pallet PA1 is completed, the buffer material PA13 is often deformed to some extent due to long-term compression, but the base board PA11 and the additional circuit board PA15 made of wood materials are usually not damaged permanently; therefore, after the heavy cabinet is transported to the destination, the buffering material PA13 is generally disposed of in a waste manner due to possible deformation, recycling of the overall conventional buffering pallet PA1, additional transportation cost and the like, and thus, there is obviously a problem of waste of materials (especially wood materials).

In recent years, with the increasing awareness of environmental protection, special rules are established in more countries and regions to encourage the recycling of such pallets (or punish the discarding of such pallets) by fiscal means, for example, korean has established a mandatory regulations for Packaging (New Packaging Regulation) for encouraging recycling, in which a higher tax amount is established for the discarding of Packaging materials having more than two materials (such as the buffer pallet in the present case).

Therefore, under the premise of cost control, how to design a buffer pallet which has better bearing performance, can easily disassemble the wood board and the buffer material and is convenient for recycling and reusing becomes an urgent and necessary work.

Detailed Description

Please refer to fig. 3 and fig. 4, which are a perspective view and an exploded view of a modular buffering pallet structure according to a preferred embodiment of the present invention. As shown, the modular cushioned pallet structure 1 of the present invention comprises a base plate 11, a plurality of cushioning materials 13, a reinforcing plate 15, a bearing plate 17, and a plurality of pallet coupling pairs 19; the bottom plate 11, the reinforcing plate 15 and the bearing plate 17 are usually made of wood.

The bottom plate 11 has a bottom surface 111 and a top surface 113, and further comprises a plurality of nut-setting holes 115 penetrating the thickness of the bottom plate, wherein the nut-setting holes 115 are preferably stepped holes, and the diameter of the nut-setting holes 115 is larger at the bottom surface 111 than at the top surface 113; a plurality of positioning blocks 1131 corresponding to the cushioning material 13 are disposed on the top surface 113 of the bottom plate 11, so as to position and dispose the cushioning material 13 on the top surface 113; at least one block 1133 is respectively disposed on two longitudinal sides of the top surface 113 of the bottom plate 11 (two blocks 1133 are respectively disposed on two longitudinal sides), wherein the longitudinal sides of the top surface 113 of the bottom plate 11 refer to the longitudinal sides of the top surface 113 of the bottom plate 11.

Please refer to fig. 5 and fig. 6, which are respectively a perspective enlarged view of the buffering material 13 and a perspective cross-sectional view along a line a-a in fig. 5. The cushioning material 13 of the present invention is a block made of Expanded Polyethylene (EPE) or expanded Polypropylene (EPP), and is disposed in a scattered manner (in this embodiment, disposed in a 3 × 3 matrix), on the top surface 113 of the bottom plate 11, each cushioning material 13 further includes at least one bolt through hole 131 (two through holes in the figure) penetrating the thickness of the cushioning material, a bottom edge positioning recess 133 convenient for being aligned with the positioning block 1131 of the bottom plate 11, and at least one top surface recess 135 (two recesses in the figure), wherein the top surface recess 135 is used to make the cushioning material 13 form a secondary cushioning structure (similar to two coaxially nested and unequal high compression springs). It should be noted that the height of the stop 1133 on the bottom plate 11 is lower than the height of the cushioning material 13, so that the cushioning material 13 can perform its load-absorbing function, and the stop 1133 can also limit the downward displacement of the bearing plate 17 and the reinforcing plate 15.

In the present invention, the stop 1133 also has a positive transportation fool-proofing function. Since the heavy body carried by the pallet is generally heavier at the front than at the rear, the fork advance direction during the transportation of the machine is generally performed in a longitudinal fork advance manner (along the length direction of the pallet) when the pallet is designed, but the side edges of the conventional buffer pallet PA1 in the length direction as shown in fig. 1 and 2 do not have an obstacle to the fork advance, so that there is a risk that the pallet is unbalanced left and right due to wrong lateral fork advance. In contrast, the present invention provides at least one stop 1133 at a suitable position on the side of the base plate 11 to block the lateral feed of the fork arm of the handling apparatus, in turn eliminating the operational risk caused by possible load imbalances.

Furthermore, in the prior art, the existing buffer pallet PA1 (see fig. 1) has no design for avoiding direct collision or buffering collision force on both sides; based on this, the modular buffering pallet structure 1 of the present invention further includes a plurality of anti-impact wing plates 137 disposed at the outer edges of the pallet length direction side edges, so as to protrude from the side edges of the modular buffering pallet structure 1 after the modular buffering pallet structure 1 is assembled (as shown in fig. 3). In the embodiment, the impact-resistant wing plates 137 and the corresponding buffer materials 13 are integrally formed and disposed at the same height or slightly lower than the same height, so that the buffer materials 13 disposed on the lengthwise side of the pallet have the functions of vertical load-bearing buffering and lateral collision buffering.

In this embodiment, the bottom plate 11 may be composed of a plurality of elongated plates (three longitudinal plates and two transverse plates as shown in fig. 4), and the cushioning material 13 is distributed on the longitudinal rows of elongated plates. As shown in fig. 5, each of the cushioning materials 13 may further include a downward protruding lower protrusion 1371, and the bottom space of the cushioning material 13 defined by the two lower protrusions 1371 is just suitable for the cushioning material 13 to straddle the corresponding elongated plate, so as to achieve the positioning and fixing effects; preferably, lower flange 1371 may be formed directly from adjacent impact resistant wing plates 137, extending downward in an integrally formed manner.

Referring to fig. 3 and 4, the bearing plate 17 is disposed above the buffering material 13, and further includes a plurality of bolt insertion positions 171 penetrating the thickness of the bearing plate 17 for directly bearing the heavy cabinet, which can be directly disposed on the buffering material 13, but in order to enhance the load-bearing capacity, it is preferable to dispose a parallel reinforcing plate 15 below the bearing plate 17, the lower edge of the reinforcing plate 15 contacts each buffering material 13, and the reinforcing plate 15 further has a plurality of through holes 151, bolt insertion positions 171 respectively corresponding to the bearing plate 17, bolt through holes 131 of the buffering material 13, and nut installation holes 115 of the base plate 11 for passing bolts 191 of the corresponding pallet combination pair 19.

In this embodiment, the reinforcing plate 15 is composed of a plurality of long plates (three longitudinal and four transverse directions as shown in fig. 4), and the cushioning material 13 is disposed under the long plates in a dispersed manner; in this embodiment, each of the buffer materials 13 may further include an upper protruding edge 1373 protruding upward to allow the corresponding elongated plate of the reinforcing plate 15 to be disposed on the corresponding buffer material 13, and the top space of the buffer material 13 defined by the two upper protruding edges 1373 just allows the width of the elongated plate of the reinforcing plate 15 to be limited on the buffer material 13, so as to achieve the positioning and stable disposition effect; preferably, upper flange 1373 may be formed directly from adjacent impact resistant wing panel 137, extending upwardly in an integrally formed manner.

Referring to fig. 3, 4, and 7 to 9, fig. 7 is a schematic diagram of the pallet combination according to an embodiment of the present invention, fig. 8 is a schematic perspective sectional view taken along line B-B of fig. 3, and fig. 9 is an enlarged schematic diagram of area C of fig. 8. As shown, the pallet coupling pairs 19 are adapted to threadedly lock the base 11, the cushioning material 13, the reinforcing plate 15 (when selected) and the bearing plate 17 together, and each pallet coupling pair 19 further includes a bolt 191 and an anchor threaded base 193, wherein the anchor threaded base 193 is disposed in the corresponding nut-receiving hole 115 of the bottom surface 111 of the base 11.

As shown in fig. 7, the anchoring threaded base 193 of the present embodiment includes a central internally threaded cylinder 1931 and at least one peripherally projecting spike body 1933 facing the bottom plate 11, the central internally threaded cylinder 1931 having an internal thread for engaging the external thread of the end of the bolt 191, and the peripherally projecting spike body 1933 being spaced apart from the central internally threaded cylinder 1931 for penetrating upwardly into the bottom plate 11. When the anchor threaded base 193 is first applied to the base plate 11, the anchor threaded base 193 is inserted into the nut setting hole 115 from the bottom 111 of the base plate 11, and the spike body 1933 protruding from the periphery thereof penetrates into the material of the base plate 11 adjacent to the upper end of the stepped nut setting hole 115 to position the anchor threaded base 193 in the anchor threaded base 193 of the base plate 11, so that the anchor threaded base 193 is fixed to the base plate 11 during the subsequent application of the modular buffer pallet structure 1 without being disassembled or assembled.

In the present invention, when assembling the modular buffer pallet structure 1, the bolt 191 penetrates the bearing plate 17, the reinforcing plate 15 (when selected), the buffer material 13 and the base plate 11, and is screwed with the central internal threaded column 1931 of the anchoring threaded base 193 fixed on the base plate 11 with a predetermined locking force.

In the present invention, because both wood and EPE or EPP materials are compressible materials, when the modular buffer pallet structure 1 is locked by the pallet combination pair 19, the magnitude of the locking force must be limited to avoid the phenomenon of poor manufacture due to excessive deformation of the board or the buffer material caused by too large locking force. In an application example, taking the bolt 191 with a thread length of 15mm at the end as an example, the thread length of the internal thread of the central internal threaded cylinder 1931 of the anchoring threaded base 193 should also be equal to or slightly less than 15mm, and at this time, a locking length of 3mm can be reserved when the bolt 191 is locked, and once the bolt is locked to a predetermined stroke (15mm), the locking cannot be continued, so that the magnitude of the locking force can be effectively limited.

In the present invention, the modular cushioning material 13 is preferably manufactured by having the impact resistant wing plate 137 with two sides for cushioning side impact, the lower flange 1371 with two sides for providing space for straddling the elongated slat of the base plate 11, and the upper flange 1373 with two sides for providing space for receiving the elongated slab of the reinforcing plate 15, and the impact resistant wing plate 137, the lower flange 1371, and the upper flange 1373 are integrally formed with the block of cushioning material 13. The cushion material 13 of this structure can be applied to the embodiment of the bottom plate 11 and the reinforcing plate 15 made of long plates, but in the embodiment of the bottom plate 11 and the reinforcing plate 15 made of continuous plates or without the reinforcing plate 15, part of the lower flange 1371 and the upper flange 1373 obviously cause the problem of structural interference during assembly, but since the cushion material 13 is made of EPE or EPP foam material, the lower flange 1371 or the upper flange 1373 of the protruding block can be easily cut off before the cushion material 13 is assembled, thereby avoiding the structural interference during assembly and simplifying the production of the cushion material 13.

In the present invention, when the modular buffering pallet structure 1 is to be assembled, a plurality of buffering materials 13 are disposed between the base plate 11 and the bearing plate 17 (including the reinforcing plate 15), and then the bolt 191 of each pallet combination pair 19 is sequentially passed through the corresponding bolt penetration position 171 on the bearing plate 17, the corresponding through hole 151 on the reinforcing plate 15 (if selected), the bolt through hole 131 corresponding to the buffering material 13, and the corresponding nut setting hole 115 on the base plate 11, and then screwed with the anchoring threaded base 193 disposed in the corresponding nut setting hole 115 on the bottom surface 111 of the base plate 11, and the bolt 191 is screwed with the anchoring threaded base 193 with a predetermined locking force.

In addition, when the modular cushioned pallet structure 1 is disassembled, each bolt 191 is rotated away from the locked anchoring threaded base 193 to separate the base 11, the cushioning material 13, the reinforcing plate 15 (if desired) and the load bearing plate 17, and the base 11, the reinforcing plate 15 (if desired), the load bearing plate 17 and the pallet combination pair 19 are typically recycled.

As mentioned above, since the modular buffering pallet structure of the present invention adopts a modular design, and the shock-resistant wing plate, the upper and lower positioning flanges and the buffering material can be integrally formed, the pallet can be assembled or disassembled by combining the pallet screwed with a predetermined locking force, thereby not only realizing the effects of easy manufacture and easy recycling, but also substantially reducing the material and tax costs for the application of the buffering pallet.

The above detailed description of the preferred embodiments is intended to more clearly illustrate the features and spirit of the present invention, and is not intended to limit the scope of the present invention to the particular embodiments disclosed above.
