Description

  The present invention relates to a resin pallet.

  Until now, most of the “pallets”, which are rectangular cargo beds used for cargo handling operations using forklifts, have been wooden. In recent years, those made of resin have also increased along with consideration for the natural environment and ease of manufacture by integral molding.

  However, the resin pallet is easy to mold, but the strength and rigidity may be insufficient depending on the shape. For example, a plastic pallet that does not have a bottom deck (upper deck and bar structure only), that is, an asymmetric plastic pallet, breaks when the load is placed because the strength and rigidity are unbalanced on the top and bottom of the pallet. It has become easier.

  Therefore, in order to prevent such damage to the resin pallet, various techniques for applying a reinforcing structure to the pallet have been developed (for example, Patent Document 1). In addition, also in the wooden pallet, patent document 2 etc. exist as a reinforcement structure.

  On the other hand, the inventor of the present application aims to increase the strength and rigidity of a resin pallet (especially a vertically asymmetric resin pallet) with a novel structure that has never been achieved to prevent breakage. It came to complete.

1st invention of this invention is based on the direct support system (the 1), It is a resin pallet provided with the deck which has the mounting surface which mounts a load, Comprising: The insertion side which inserts the fork of a forklift It is a resin pallet with a reinforcing material, characterized in that a reinforcing material is provided at the end of the deck for supporting the loaded object.
A second aspect of the present invention is the resin pallet with the reinforcing material, wherein the reinforcing material is U-shaped or L-shaped in cross section.
A third invention is based on a direct support system (part 2), and is a resin pallet provided with a deck having a placement surface on which a load is placed, and the load is placed on the placement surface of the deck. It is a resin pallet with a reinforcing material provided with a reinforcing material that contacts and supports the material.
4th invention is a resin pallet with the said reinforcing material, The said reinforcing material is a frame.
A fifth invention is based on an indirect support system, and is a resin pallet provided with a deck having a mounting surface on which a load is placed, and the load is supported on the back surface of the end of the loading surface of the deck. It is the resin pallet with a reinforcing material characterized by including the reinforcing material to perform.
A sixth invention is a resin pallet with the reinforcing material, wherein the reinforcing material is a round pipe or a square pipe.
According to a seventh aspect of the present invention, the resin pallet (main body) has a top deck having a placement surface on which a load is placed and a crosspiece structure on which the fork of a forklift can be inserted on the bottom surface thereof. It is characterized by being asymmetrical not in the vertical direction.

The present invention has the following effects.
(1) Since the reinforcing material attached to the resin pallet directly or indirectly supports the load, it is concentrated on a part of the resin pallet main body and no load is applied, increasing the strength and rigidity of the pallet main body. , Can prevent the damage.
(2) That is, in the present invention, the reinforcing material is the “main” that supports the load, and the resin pallet main body has a “secondary” relationship that fixes the reinforcing material. On the other hand, the conventional reinforcing structure is merely a “subordinate” of the resin main pallet body that supports the load. Therefore, it can be said that the present invention is a completely different reinforcing structure from the conventional reinforcing structure.
(4) Especially, in the case of an asymmetric plastic pallet that does not have a bottom deck (only the top deck and crosspiece structure), the load is placed because the strength and rigidity are unbalanced on the top and bottom of the pallet. However, the damage can be prevented by providing this reinforcing material.
(5) In addition, if the asymmetrical plastic pallets that do not have a bottom deck (top deck and bar structure) can be used safely, the loading capacity (trucks, etc.) can be used when only the pallets are transported (such as when returned). Will contribute to cost reduction and transportation efficiency.
(6) By providing such a reinforcing material, even if the resin pallet is damaged due to aging or the like, it can be used as it is.

  Embodiments of the present invention will be described with reference to the drawings. Note that, here, a description will be given of a resin pallet (main body) that is not vertically provided (only the top deck and the crosspiece structure) and is asymmetrical, but the present invention is not limited to this.

FIGS. 1-6 is explanatory drawing which shows 1st Embodiment (direct support system: the 1) of this invention.
First, as shown in FIGS. 1 to 4, the resin pallet 10 includes an upper deck 11 having a mounting surface 12 on which a load 90 (for example, a floor panel) is mounted, and a forklift fork lift on the lower surface side. It is a resin pallet which is vertically asymmetrical and has a crosspiece structure 15 that can be inserted. Reinforcing members 20 and 20 are provided at end portions 13 and 13 of the upper surface deck 11 on the insertion side into which the fork of the forklift of the resin pallet 10 is inserted.

  The reinforcing member 20 has a U-shaped cross section and is attached so as to be inserted into the end portion 13 (not shown, but may be fixed with screws). Then, as shown in FIG. 3, the reinforcing member 20 contacts the load 90 and directly supports the load 90. Since the reinforcing material 20 directly supports the load 90, it is concentrated on a part of the resin pallet 10 and no load is applied, and the strength and rigidity of the pallet are increased, and the breakage thereof can be prevented. Note that the dimensions of the reinforcing material 20 (for example, X in FIG. 4) can be changed according to the weight of the load 90 (for example, if the weight is heavy, X is lengthened), thereby supporting various loads 90. can do. Further, the reinforcing member 20 is preferably made of metal having high strength and rigidity in order to support the load 90, but is not limited thereto.

The load 90 placed on the resin pallet 90 is fixed with a band 95 or the like so that the load does not collapse during transportation (see FIG. 3). However, there is no risk of the band 95 being cut.
FIG. 4 illustrates another embodiment of the reinforcing member 20, in which an anti-slip function 22 is provided on the contact surface 21 that contacts the load 90. FIG. 4A shows the surface of the contact surface 21 roughened (satin surface), and FIGS. 4B to 4D show the surface of the contact surface 21 provided with irregularities.

  Next, the reinforcing member 30 illustrated in FIG. 5 has an L-shaped cross section. Various sizes of the reinforcing material 30 can also be obtained by changing the dimensions (for example, X and Y in FIG. 5) according to the weight of the load 90 (for example, when the weight is heavy, X and Y are lengthened). 90. The other parts are the same as those of the reinforcing member 20, and the description thereof is omitted.

  Next, the reinforcing member 40 illustrated in FIG. 6 has an elongated rectangular shape. Also in the reinforcing material 40, the dimensions (for example, X in FIG. 6) are changed according to the weight of the load 90, etc. (when the weight is heavy, X is lengthened, etc.), so that it corresponds to various loads 90. be able to. The other parts are the same as those of the reinforcing member 20, and the description thereof is omitted.

FIG. 7 is an explanatory view showing a second embodiment (direct support method: part 2) of the present invention.
The reinforcing material 50 shown in FIG. 7 is common to the above-described reinforcing materials 20, 30, and 40 in that it directly contacts the load 90 and directly supports the load 90. 12 in that it is in contact with and supports the load 90.
The reinforcing member 50 is a frame for widely contacting the load, but is not limited to the shape of the eye as shown. Since the reinforcing material 50 also directly supports the load 90, it is concentrated on a part of the resin pallet 10 so that no load is applied, the strength and rigidity of the pallet are increased, and breakage thereof can be prevented.

FIG. 8 is an explanatory view showing a third embodiment (indirect support system) of the present invention.
The reinforcing material 60 illustrated in FIG. 8 is different from the above-described reinforcing materials 20, 30, 40, and 50 in that the loaded material 90 is indirectly supported without contacting the loaded material 90. However, indirectly, since the reinforcing material 60 also supports the load 90, it is concentrated on a part of the resin pallet 10 so that no load is applied, and the strength and rigidity of the pallet are increased, and the damage can be prevented.
In FIG. 8A, a reinforcing member 60 that supports the load 90 is provided on the back surface of the mounting surface 12 end (end portion 13) of the upper surface deck 11 facing the insertion side into which the fork of the forklift is inserted. However, in order to further increase the strength and rigidity, a reinforcing material 60 may be provided on the back surface near the center of the placement surface 12 of the top deck 11.
The illustrated reinforcing member 60 is a round pipe, but may be a square pipe or other member. Moreover, you may employ | adopt arbitrary methods for the method of attaching the reinforcing material 60 to a resin pallet.

9 and 10 are explanatory diagrams for explaining the effect of the present invention.
According to the present invention, the use of the reinforcing members 20, 30, 40, 50, 60, etc. is sufficient even in the vertically asymmetric resin pallet 10 having only the upper surface deck 11 and the crosspiece structure 15 without the lower surface deck. Strength and rigidity can be obtained. When such a vertically asymmetric resin pallet 10 is widely used, the loading amount (with respect to a truck or the like) increases when only the resin pallet 10 without the load 90 is transported (for example, when returned). This will contribute to cost reduction and transportation efficiency.

That is, as shown in FIG. 9, the vertically asymmetric resin pallet 10 does not have a bottom deck, and can be compactly accommodated by combining the crosspiece structures 15.
On the other hand, in the case of the vertically symmetrical pallet 80 having the bottom deck, as shown in FIG. 10, the pallets can only be stacked as they are, so that they cannot be accommodated in a compact manner.
Therefore, if the vertically asymmetric resin pallet 10 can be widely used according to the present invention, it will contribute to cost reduction, transportation efficiency, and the like, and a great merit can be enjoyed.

  The present invention is not limited to resin pallets but can be widely used in the pallet field.
