Technical field

[0001] The present invention relates to a synthetic resin pallet that is used when transporting and storing various cargoes, and relates to a synthetic resin pallet that can be transported by a forklift or a pallet truck.

Background art

[0002] Generally, synthetic resin pallets molded by injecting synthetic resin are provided as pallets used for transporting and storing luggage, and forklifts and other fork parts can be inserted from two directions. Two-way synthetic resin pallets and four-way synthetic resin pallets that can be inserted from four directions are used (see, for example, JP-A-2001-72063 and JP-A-2000-16430).

[0003] This kind of synthetic resin pallet is composed of an upper surface plate-like portion and a lower surface plate-like portion arranged in parallel with each other, and a girder portion connecting the upper surface plate-like portion and the lower surface plate-like portion. The upper surface plate-like portion and the lower surface plate-like portion are connected to each other by girders arranged at both ends and in the middle, and a pair of fork insertion holes are formed between the upper surface plate-like portion and the lower surface plate-like portion. ing. In other words, the side surface surrounding the outer peripheral portion between the upper surface plate-shaped portion and the lower surface plate-shaped portion is provided with a girder portion and an opening portion of a fork insertion hole.

[0004] Synthetic resin pallets are used to transport and store packages in bulk. Specifically, with a load placed on the upper surface, a fork lift or a pallet truck fork is inserted into a pair of fork insertion holes and transported with a synthetic resin pallet and placed on a truck bed or a warehouse.

Here, the luggage may be fixed with a rope so that the luggage placed on the plastic pallet does not collapse.

Conventionally, when a baggage on a synthetic resin pallet is fixed with a rope, the rope is inserted into a fork insertion hole provided in a side surface portion of the synthetic resin pallet so that the upper plate-like portion and the baggage are connected. I was tied up. Since it is necessary to pass the rope through the pallet through the fork insertion hole, Fixing things took a lot of time and effort.

In addition, when the rope is inserted into the fork insertion hole as described above, the rope may move in the fork insertion hole, and the rope will loosen due to vibration during transportation of the synthetic resin pallet, causing the luggage to collapse. There was a risk of it.

Furthermore, the rope may be damaged by the fork inserted into the fork insertion hole, and the rope may be cut.

[0006] Thus, as shown in FIG. 9, a synthetic resin pallet is provided in which a hook portion for hooking a rope is provided on a side surface portion. In the synthetic resin pallet with this configuration, the rope can be hooked on the hook to secure the load on the synthetic resin pallet, and the load can be transported and stored stably.

With this synthetic resin pallet, it is not necessary to pass the rope through the fork insertion hole, so the work for fixing the load can be performed easily. Moreover, since the rope is hooked at the hook portion, the rope is prevented from moving and loosening during transportation, and the load can be prevented from collapsing. Also, there is no risk that the rope will be cut without the fork part coming into contact with the rope.

[0007] By the way, in the synthetic resin pallet provided with a hook portion for hooking the rope on the side surface portion, as shown in Fig. 9, after unpacking, the synthetic resin pallet remains hooked on the hook portion. Made pallets may be stored.

Problems to be solved by the invention

[0008] In a synthetic resin pallet in which no load is placed on the upper surface and no rope is used, the rope hooked on the hook portion is bundled and placed on the upper surface of the synthetic resin pallet. In this case, the plastic pallets to be stacked ride on the rope and tilt, and there is a problem when a plurality of plastic pallets cannot be stably stacked.

As shown in Fig. 9, when the rope is left on the floor, the rope is pulled when the rope is stepped on with a forklift, etc., and the stacked synthetic resin pallets collapse or the hook part Problems such as breakage or broken rope was there.

[0009] Furthermore, when the rope hangs down from the side surface, the fork insertion hole is hidden and the fork cannot be easily inserted. In addition, when the synthetic resin pallets are placed side by side, the rope hanging from the side surface gets in the way, so a lot of space was required to store the synthetic resin pallets.

In addition, if the rope is put in the fork insertion hole, it is difficult to see the rope from the outside, and when the fork is inserted into the fork insertion hole, the rope is caught by the fork. This could cause troubles such as breakage of the hook or cutting of the rope.

[0010] The present invention has been made in view of such circumstances, and provides a synthetic resin pallet capable of stably storing a rope in a hook portion for hooking when the rope is not used. Objective.

Means for solving the problem

[0018] Hereinafter, a description will be given with reference to the accompanying drawings of a pallet made of synthetic resin which is useful in an embodiment of the present invention.

1 to 7 show a synthetic resin pallet according to an embodiment of the present invention.

As shown in FIG. 1, the synthetic resin pallet 11 is formed in a rectangular box shape as a whole, and an upper surface plate portion 12 that forms the upper surface of the synthetic resin pallet 11 and a lower surface plate portion 13 that forms the lower surface. The upper plate-like portion 12 and the lower plate-like portion 13 have a girder portion 14 connected thereto. The upper surface plate-like portion 12 and the lower surface plate-like portion 13 are arranged so as to be substantially parallel as shown in FIGS.

The synthetic resin pallet 11 is made of an olefin-based resin such as polyethylene or polypropylene, for example, and includes an upper surface mold member in which an upper surface plate portion 12 and a girder portion 14 are integrally formed, and a lower surface plate portion 13. Formed by heat-welding the lower surface mold member formed integrally with the beam portion 14 with the beam portion 14 of the upper surface mold member and the beam portion 14 of the lower surface member being in contact with each other. .

Alternatively, the synthetic resin pallet 11 may be formed by integrally molding the upper plate portion 12, the lower plate portion 13, and the girder portion 14. [0020] Between the beam portions 14 of the synthetic resin pallet 11 configured in this way, a pair of fork insertion holes 21, 21, and 22, 22 for inserting the fork portions of the forklift truck palette truck. Two sets are formed. The fork insertion holes 21, 21 extending in the long side direction of the pallet 11 have openings 21A, 21A on both side surface parts 15 on the short side, and the fork insertion holes 22, 22 extending in the short side direction are on the long side side. Opening portions 22A, 22A are provided on both side surface portions 15 of the pallet, and a so-called four-way synthetic resin pallet 11 is formed. That is, the short side surface portion 15 constituted by the girder portion 14 and the openings 21A and 21A of the fork insertion holes 21 and 21, and the opening portion 22A of the girder portion 14 and the fork insertion holes 22 and 22 and The side part 15 of the synthetic resin pallet 11 is formed by placing the long side side part 15 constituted by 22A in contact with the long side part 15. The side surface portion 15 surrounds the outer peripheral portions of the upper surface plate portion 12 and the lower surface plate portion 13.

[0021] In the bottom plate-like portion 13, the region that forms the bottom of the fork insertion holes 21 and 21, that is, the direction perpendicular to the insertion direction of the fork lift or pallet truck fork between the spar 14 and 14 A plurality of crosspieces 23 and 23 are spaced apart from each other. Similarly, a plurality of crosspieces 24 and 24 are spaced apart from each other along the region that forms the bottom of the fork insertion holes 22 and 22, that is, between the spar 14 and the spar 14, along the direction perpendicular to the insertion direction of the fork. It is provided with a gap.

Here, the height of the crosspiece 23 arranged at the bottom of the fork insertion holes 21 and 21 provided with the openings 21A and 21A on the short side 15 is equal to the opening 22A on the long side 15 And 22A are set so as to be lower than the height of the crosspiece 24 arranged at the bottom of the fork insertion holes 22 and 22 provided with 22A.

Further, a plurality of wheel holes 25 communicating with the fork insertion holes 21 and 21 are formed in the region between the beam portions 14 in the lower surface plate-like portion 13. When the pallet truck is inserted into the fork insertion holes 21 and 21, the pallet truck wheel can be grounded through the wheel hole 25.

In the synthetic resin pallet 11 of this specific example, since four wheel holes 25 are formed, the lower surface plate-like portion 13 has a quadrangular shape with a cross formed in the center by the crosspieces 23 and 24. [0023] On the other hand, the upper surface of the plastic pallet 11, that is, the surface of the upper surface plate-like portion 12 constitutes a loading surface for loading various kinds of cargo so that the cargo can be placed in a stable state. It is formed flat. As shown in FIG. 1, a plurality of lattice-like ribs 16 are formed on the upper plate-like portion 12 to reinforce the region between the girder portions 14. A rectangular chamber portion 17 is formed.

Further, projections projecting upward are provided at the respective edges of the four sides of the upper surface plate-like portion 12. Further, when the pallets are stacked, a groove that can accommodate the protrusion is provided in the portion of the lower surface plate-like portion 13 that faces the protrusion of the upper surface plate-like portion 12. In this way, the protrusions projecting upward are provided at the respective edges of the four sides of the upper surface plate-like portion 12, and the lower surface plate-like portion 13 is provided with a groove capable of accommodating it, so that the pallet can be stably moved without being displaced. Can be stacked.

[0024] A hook portion 18 for hooking the rope R is formed in the spar portion 14 located on the side surface portion 15 surrounding the outer periphery of the upper surface plate-like portion 12 and the lower surface plate-like portion 13. . As shown in FIG. 4, the hook portion 18 has a concave portion 19 having a substantially rectangular cross section formed by recessing the side surface portion 15, and extends vertically from the upper surface plate-like portion 12 side to the lower side of the concave portion 19. It consists of an arrow part 20. A key portion for preventing the rope R from coming off is provided at the tip of the arrow portion 20.

The hook portions 18 are formed on the spar portions 14 of the four side surface portions 15 of the synthetic resin pallet 11 so as to be symmetrical with respect to the opposing side surface portions 15.

The plate-like member 12 is formed with an accommodation recess 31 for accommodating the rope R that is hooked on the hook portion 18. In the synthetic resin pallet of the present embodiment, the position facing the hook portion 18 via the side surface portion 15, more specifically, the accommodating recess 31 is formed inside the girder portion 14. The accommodating recess 31 has a substantially bottomed polygonal cylindrical shape, and has, for example, a rectangular cross section similar to the rectangular chamber portion 17 without the bottom surface portion 33. As shown in FIG. 5 and FIG. 6, the housing recess 31 is a bottom surface portion positioned in parallel to the lower surface plate-like portion 13 in contact with the four side wall surfaces 32 which are ribs and the lower end of the four side wall surfaces. It consists of 33. A drain hole 34 is formed in the side wall surface 32 and the bottom surface portion 33.

[0026] As described above, the bottom portion 33 is provided in the receiving recess 31. The rectangular chamber portion 17 other than the receiving recess 31 extends downward from the upper plate-like portion 12 as shown in FIG. like, Alternatively, the rib 16 is only formed so as to extend upward from the lower surface plate-like portion 13, and the bottom surface portion 33 is not provided.

[0027] The synthetic resin pallet 11 configured as described above has a forklift or a pallet truck in a pair of fork insertion holes 21, 21 or 22, 22 in a state in which a load is placed on the surface of the upper plate 12. The fork part is inserted and the plastic pallet 11 is placed on the truck bed or warehouse, and the goods are transported and stored together.

[0028] Here, the fork portion of the forklift is inserted into the fork insertion holes 22, 22 having the openings 22A, 22A on the long side, and the synthetic resin pallet 11 is transported.

On the other hand, as described above, the fork insertion holes 21 and 21 having the openings 21A and 21A on the short side are provided with the crosspieces 23 having a low height. For this reason, even in the case of a pallet truck provided with a wheel or the like near the tip of the fork, the wheel or the like near the tip easily gets over the beam 23. As a result, the wheel of the pallet truck comes into contact with the floor via the wheel hole 25, and the pallet can be transported by the pallet truck.

In other words, the fork insertion holes 22 and 22 opened on the long side are suitable for transportation by a forklift, and the fork insertion holes 21 and 21 opened on the short side are used for transportation by a forklift and a pallet truck. In particular, it is preferably used for transportation by pallet truck.

[0029] Next, an operation for fixing the luggage on the synthetic resin pallet 11 with the rope R will be described. Fig. 8 shows the state where the load on the plastic pallet 11 is fixed with the rope R. First, the rope R is inserted into the hook portion 18 provided on the side surface portion 15, for example, a loop formed on one end side of the rope R is inserted into the concave portion 19, and the arrow portion 20 is arranged in the loop. Hang.

[0030] The rope R used here is a belt having a substantially flat cross section, but of course, the same can be used even if the cross section is circular.

Pass the rope R, one end of which is hooked to the hook part 18, over the load on the plastic pallet 11 and hook the other end to the hook part 18 formed on the side part 15 facing the rope R. Then, the remaining portion of the rope R is locked by a locking member (not shown), and the rope R is tied in a tension state. [0031] In the synthetic resin pallet 11 after unpacking, the plate-like member 12 has an accommodation recess 31 formed therein. More specifically, an accommodating portion is formed at a position facing the hook portion 18 via the side surface portion 15, that is, the hook portion 18 and the accommodating recess 31 are provided close to each other. In particular, the housing recess 31 is formed inside the girder 14. For this reason, the rope R, one end of which is hooked on the hook portion 18, can be rolled up and accommodated in the accommodation recess 31, so that the rope R can be prevented from being left on the floor. Therefore, if the synthetic resin pallet 11 piled up by stepping on the rope R left on the floor with a forklift collapses, the hook part 18 breaks, or the rope R breaks, the trouble is Can be prevented.

In particular, when the hook portion 18 and the accommodation recess 31 communicate with each other, the recess portion 19 of the hook portion 18 and the rope R can be pushed in and accommodated in the accommodation recess 31. Accordingly, the rope R can be accommodated in the synthetic resin pallet 11 even after the synthetic resin pallets 11 are stacked on the synthetic resin pallets 11 other than the uppermost stage after the plurality of synthetic resin pallets 11 are stacked. Furthermore, since the rope R can be accommodated inside the plastic pallet 11, the storage space for the plastic pallet 11 is reduced so that the rope does not interfere with the placement when the plastic pallets 11 are stacked or arranged. can do. In particular, when the rope R is flat, the plastic pallets can be stacked more stably and the storage space can be reduced.

[0032] Since the bottom portion 33 is formed in the housing recess 31, when the rope R is received in the housing recess 31, the rope R is exposed to the fork insertion holes 21, 21 or 22, 22 or the floor surface. The rope R can be securely stored.

Further, since the accommodating recess 31 is provided in the girder part 14 and formed up to the vicinity of the lower surface plate-like part 13, a capacity can be secured and even a relatively long rope R can be reliably accommodated.

[0033] Since the drainage hole 34 is provided in the bottom surface 33 and the side wall of the housing recess 31, water does not collect in the housing recess 31, so that water will soak into the rope R, and a hand is required while fixing the luggage. It can prevent slipping.

[0034] The synthetic resin pallet according to the embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and is appropriately changed without departing from the spirit of the pallet. Is possible.

For example, the force described with the accommodating recess 31 having a rectangular cross-section is not limited to this, and may be a triangular, pentagonal, or circular cross-section.

[0035] Further, the fork insertion hole has been described as a so-called four-way synthetic resin pallet that can penetrate the synthetic resin pallet from two directions and insert the fork portion from four directions.

. However, this is not limited to this. Fork piercing hole force Only the si direction can penetrate the synthetic resin pallet, and the fork can be inserted from two directions. A synthetic resin pallet may be used.

Industrial applicability

[0036] According to the synthetic resin pallet of the present invention, since the housing concave portion that can accommodate the rope hooked to the hook portion is provided, the rope when not in use is left on the floor surface. Can be prevented. Therefore, it is possible to prevent troubles such as breakage of the hook portion and cutting of the rope R, which can prevent the rope from being stepped on with a forklift.

In addition, since the rope can be accommodated in the accommodation recess of the upper plate-like portion, the pallet can be stably stacked, and the rope does not interfere when the synthetic resin pallets are placed side by side. Therefore, the storage space for the synthetic resin pallet can be reduced. Further, since the rope does not hang down on the side surface, the fork can be easily inserted into the fork insertion hole.

As described above, according to the present invention, the load on the synthetic resin pallet can be easily and securely fixed with the rope, and the hook is hooked to the hook portion when the rope is not used. It is possible to provide a synthetic resin pallet that can be stored stably even with the mark attached.
