Description

  The present invention relates to a pallet on which a material to be transported such as a ceramic-type exterior material is loaded and transported or stored.

Conventionally, as an exterior plate to be attached to an outer wall of a building, for example, there is a rectangular ceramic industry exterior plate such as a ceramic industry siding, and the exterior plates are stacked and stored on a pallet or transported to a construction site or the like. As such a pallet, for example, a wooden pallet 100 shown in FIG. 5 is used. The pallet 100 is configured by fixing a plurality of vertical bars 101 arranged in parallel and a plurality of horizontal bars 102 arranged in a direction substantially orthogonal to the upper surface and upper and lower surfaces thereof with nails or the like.
A pair of insertion openings 103 is provided at the center of the side surface of the pallet 100. Each insertion port 103 forms a space with two vertical bars 101 on both sides and a horizontal bar 102 on the upper surface side, and a reinforcing plate 104 is provided between the two vertical bars 101 on both sides and the horizontal beam 102 on the upper surface side. Is fixed. And a pair of nail | claw part of a forklift can be inserted in the insertion port 103, and the pallet 100 which loaded the exterior board can be lifted.

In this pallet 100, an exterior plate is stacked and placed on the upper surface, and the forklift claw is inserted into the insertion port 103 between the vertical bars 101, and the tip of the claw is placed on the end surface of the insertion port 103 of the pallet 100. There is a risk of collision and damage.
Further, even when the claw portion is inserted into the insertion port 103 of the pallet 100 and lifted by a forklift, the weight of the exterior plate is large, so that the outside of the pallet 100 bends downward with the pair of claw portions of the forklift as a boundary. In some cases, a load is intensively applied to the end portion of the exterior plate located above the base portion of the claw portion, and the end portion of the exterior plate may be damaged.

In order to prevent such cracks and damage to the pallet, for example, a wooden pallet described in Patent Document 1 has been proposed. In this pallet, a plurality of horizontal rails are arranged in an orthogonal manner and fixed to the upper and lower surfaces of a plurality of baseboards made of wooden squares. Moreover, a protective plate made of plastic or metal plate is fixed to the upper and lower ends of the forklift insertion port between the pair of baseboards.
The protective plate has a substantially L-shaped frame plate, and a plurality of frame portions provided with openings in a rectangular insertion slot partitioned by left and right baseboards and upper and lower horizontal rails are arranged in the arrangement direction of the baseboards. And is formed by an integrated frame plate member.

However, the wooden pallet described in Patent Document 1 has a drawback in that the material cost is increased because a protective plate made of a different material other than wood is used as the reinforcing protective plate. Moreover, it is not preferable to increase the cost by using a high-strength dissimilar material.
Also, if the pawl of the forklift is accidentally collided with the protective plate, or repeatedly inserted into the pallet through the opening of the protective plate and lifted to transport the exterior plate, the pallet that secures the protective plate or protective plate The side rail will be damaged. In that case, the protection plate and the horizontal rail to which the protection plate is fixed must be replaced and fixed, and there are disadvantages that the replacement work takes time and costs increase.

  The present invention has been made in view of the above problems, and prevents the pallet from being damaged when the forklift claw portion is inserted, resulting in a decrease in strength. The object is to provide an inexpensive pallet.

A pallet according to the present invention is a pallet in which a plurality of vertical bars and a plurality of horizontal bars are crossed and fixed to each other, and a pair of vertical bars positioned on both sides of an insertion portion into which a forklift claw portion is inserted. The reinforcing member is fixed to the upper part of the pair of vertical bars protruding from the horizontal bars and protruding from the horizontal bars.
According to the present invention, when inserting the claw portion of the forklift into the insertion portion of the pallet, the pallet main body can be prevented from being damaged even if it collides with and damages the pallet reinforcement member, and the reinforcement member is replaced. do it.

The reinforcing member is preferably disposed below the upper surface of the horizontal rail.
When the product is placed on the top of the horizontal rail, and the forklift claw is inserted into the pallet insertion part and lifted together with the pallet, the reinforcing member is placed below the top of the horizontal rail. Even if the reinforcing member is pressed by a load when the reinforcing member is lifted at the base of the section and the reinforcing member located at the base part of the claw part of the forklift is deflected, the reinforcing member is connected to the product on the upper surface of the horizontal rail. It is separated and can be prevented from being damaged.

A pallet according to the present invention is a pallet in which a plurality of vertical bars and a plurality of horizontal bars are fixed to cross each other, between a pair of vertical bars positioned on both sides of an insertion portion for inserting a claw portion of a forklift. A reinforcing member protrudes outward and is fixed to the upper side rail.
In the pallet according to the present invention, when the claw portion of the forklift is inserted into the insertion portion of the pallet, the main body of the pallet is not damaged even if the reinforcing member is damaged by colliding with the reinforcing member. Further, when inserting the claw portion of the forklift into the pallet, the reinforcing member is easily damaged by the claw portion, but the pallet main body is not damaged. Therefore, it is only necessary to replace the damaged reinforcing part, and the replacement cost is low. In the present invention, a reinforcing member can be attached to an existing pallet.

  According to the pallet according to the present invention, since the pallet insertion portion is provided with the reinforcing member protruding from the cross rail, even when the claw portion collides with the reinforcing member when the claw portion of the forklift is inserted, the pallet main body is damaged. Can be suppressed. Moreover, since only the replacement of the reinforcing member is required, the cost is low and the repair work is easy.

It is a perspective view of the pallet by 1st embodiment of this invention. FIG. 2 shows the pallet shown in FIG. 1, wherein (a) is a plan view and (b) is a side view. It is a front view of the pallet shown in FIG. It is a perspective view of the pallet by 2nd embodiment of this invention. It is a perspective view of the conventional pallet.

Hereinafter, a pallet according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4.
1 to 3 show a wooden pallet 1 according to a first embodiment of the present invention. This pallet 1 is used as a product, for example, for transporting and storing rectangular ceramics-type exterior plates, such as ceramic-type siding, which form the outer wall of a building.
In the wooden pallet 1 according to the present embodiment, a plurality of vertical bars 2 made of, for example, square bars are arranged in parallel at predetermined intervals, and the upper and lower surfaces thereof are, for example, thin plate-like horizontal bars in a direction perpendicular to the vertical bars 2. For example, four sheets 3 are arranged at predetermined intervals, and are fixed to the vertical beam 2 with nails or the like. Two upper crosspieces 3 are fixed in a stacked manner in order to ensure the strength thereof, but may be a single thick plate. Each vertical beam 2 is formed to protrude outward from the horizontal beam 3 provided at both ends in the longitudinal direction. The above-described exterior plate is placed on the upper surface of the horizontal rail 3.

A pair of insertion portions 5 for inserting the forklift claw portions in a direction perpendicular to the horizontal beam 3 are formed, and the distance between the both ends of the horizontal beam 3 is set at substantially equal intervals. Yes. Therefore, it is possible to insert the claw portions of the forklift into the pair of insertion portions 5 from either direction on both sides of the pallet 1.
As shown in FIG. 2, in the insertion portion 5, in order to improve the strength of the horizontal beam 3, a short reinforcing horizontal beam 6 between each outer horizontal beam 3 and the inner horizontal beam 3. May be installed and fixed on two vertical bars 2. By stacking and fixing the two reinforcing horizontal rails 6, the pallet 1 is reinforced when the pallet 1 on which the exterior plate is placed is lifted by the claw portion of the forklift. The reinforcing cross rail 6 may be a single thick plate.

A reinforcing member 7 is fixed with a nail or the like on a pair of vertical bars 2 protruding from an outer horizontal bar 3 in the insertion portion 5. The reinforcing member 7 is fixed to the upper side of the vertical beam 2 protruding opposite to both sides of the horizontal beam 3. In addition, the reinforcing member 7 has a configuration in which the upper horizontal beam 3 is laminated, whereas it is formed on the vertical beam 2 and has the same thickness as each horizontal beam 3. In addition, it is located below the upper surface of the two cross rails 3 laminated.
Therefore, when the exterior plate is placed on the upper surface of the horizontal beam 3 of the pallet 1 along the longitudinal direction of the horizontal beam 3, the exterior plate can slightly protrude from the outer horizontal beam 3. A gap corresponding to the thickness of the horizontal rail 3 is formed between the member 7 and the exterior plate. Even if the reinforcement member 7 located at the base portion of the claw portion of the forklift is bent, a load is not intensively applied to the end portion position of the exterior plate, and the end portion of the exterior plate is not damaged.
Note that the vertical beam 2 provided in a portion other than the insertion portion 5 may not protrude outward from the horizontal beam 3. Further, the thickness of the reinforcing member 7 does not have to be equal to the thickness of the single horizontal beam 3, and may be at a position lower than the upper surface of the horizontal beam 3 while being fixed to the vertical beam 2.

The pallet 1 according to the present embodiment has the above-described configuration, and the usage method will be described next.
As shown in FIG. 1 to FIG. 3, for example, when an exterior plate is placed in two rows on the cross rail 3 on the upper surface of the pallet 1 and a predetermined number of layers are stacked, for example, the weight becomes about 1.5 tons. In this state, the exterior plate is placed on each of the two horizontal rails 3, and the end portion of the exterior plate protrudes outside the outer horizontal rail 3, but the reinforcing member 7 in the insertion portion 5. Has a gap and is not contacted.
In this state, when inserting the claw portion of the forklift into the pair of insertion portions 5 of the pallet 1 for transporting the exterior plate, the driver mistakes the height and the claw portion collides with the reinforcing member 7 and is damaged. Even if it does, it can prevent that the main body of the pallet 1 is damaged. Even when the damaged reinforcing member 7 is replaced, it is only necessary to remove only the reinforcing member 7 from the vertical beam 2 and fix the new reinforcing member 7 to the vertical beam 2 with a nail or the like.

Moreover, when the nail | claw part of a forklift is inserted appropriately in a pair of insertion part 5 of the pallet 1 and it lifts, the crosspiece 3 will be lifted by the front end side of a nail | claw part, and the base part will pressurize and lift the reinforcement member 7. FIG. At that time, there is a gap between the reinforcing member 7 and the exterior material 4, and even if the reinforcement member 7 located at the base of the claw portion of the forklift is bent, it concentrates on the end position of the exterior plate. No load is applied to the end plate, and the end of the exterior plate is not damaged.
Further, since the reinforcing member 7 is fixed to the vertical beam 2 protruding from the horizontal beam 3, it is possible to prevent the horizontal beam 3 from being damaged even if the reinforcing member 7 is broken at the claw portion of the forklift. Therefore, the pallet 1 can be prevented from being damaged due to the breakage of the reinforcing member 7, and the reinforcing member 7 may be replaced.

As described above, according to the pallet 1 according to the first embodiment, since the easily replaceable reinforcing member 7 is fixed to the vertical beam 2 protruding from the horizontal beam 3 of the pallet 1, the claw portion of the forklift is inserted into the insertion unit 5. Even if it collides with the reinforcing member 7 and breaks at that time, it is only necessary to remove the reinforcing member 7 from the vertical rail 2 and replace it, thereby preventing the main body of the pallet 1 from being damaged. Moreover, the replacement of the reinforcing member 7 is easy and can be performed at low cost.
Further, since the reinforcing member 7 is held in non-contact with the exterior plate placed on the cross rail 3, even if the reinforcement member 7 located at the base portion of the forklift claw is bent, the end of the exterior plate The load is not applied intensively to the part position, and the end of the exterior plate is not damaged.

  Note that the pallet 1 according to the present invention is not limited to the above-described embodiment, and can be appropriately changed or replaced without departing from the gist of the present invention. Although other embodiments and modifications of the present invention will be described below, the same or similar parts and members as those described in the above-described embodiments are denoted by the same reference numerals and description thereof is omitted.

Next, a pallet 1A according to a second embodiment of the present invention will be described with reference to FIG.
The pallet 1A according to the second embodiment shown in FIG. 4 is the same as the pallet 1 according to the first embodiment described above. The vertical beam 2 on both sides and the other vertical beam 2 partitioning the insertion part 5 of the claw part of the forklift are separated from the horizontal beam 3. It does not protrude outward, and has an end surface that is substantially flush with the side surface of the outer horizontal rail 3. Therefore, the pallet 1A according to the present embodiment has almost the same configuration as the pallet 100 shown in the prior art.

In the pallet 1A according to the present embodiment, the plate-like reinforcing member 9 is in contact with and protrudes from the side surface of the outer horizontal rail 3 that is flush with the end surface of the vertical beam 2 in the insertion portion 5, A support fitting 10 having a substantially L-shaped cross section is in contact with the end surface of the vertical beam 2 and is fixed with a nail or the like. The support fitting 10 is fixed to the vertical beam 2 on both sides of the insertion portion 5, and the reinforcing member 9 provided on the upper portion of the support fitting 10 is fixed to the support fitting 10 with nails or the like on both sides thereof.
In this embodiment, instead of the above-described configuration, the support fitting 10 may be fixed to the cross rail 3 and the reinforcing member 9 on the upper side of the reinforcing member 9, or the upper and lower sides of the reinforcing member 9 to increase the holding strength. You may attach the support metal fitting 10 to.

  Therefore, also in the pallet 1A according to the second embodiment, similarly to the reinforcing member 7 provided in the pallet 1 according to the first embodiment, in the vertical beam 2 on both sides and the upper and lower horizontal beams 3 that partition the pair of insertion portions 5, The reinforcing member 9 protrudes outward from the upper horizontal rail 3. Moreover, since the reinforcing member 9 is installed at a position lower than the upper surface of the upper horizontal rail 3, a gap is formed between the exterior plate placed on the horizontal rail 3 and the reinforcing member 9.

Even in the pallet 1A according to the second embodiment, when the claw portion of the forklift is inserted into the insertion portion 5 of the pallet 1A, the reinforcement member 9 can be easily replaced even if the tip of the claw portion collides with the reinforcement member 9 and is damaged. it can.
Even if the forklift claw is inserted into the insertion part 5 of the pallet 1A and lifted, the reinforcing member 9 is lifted at the base and damaged, so that the reinforcing member 9 can be removed from the vertical beam 2 or the horizontal beam 3 and replaced. Well, damage to the main body of the pallet 1 can be prevented. Moreover, since the reinforcing member 9 is held in a non-contact manner with the exterior plate placed on the horizontal rail 3, even if the reinforcement member 9 located at the base portion of the claw portion of the forklift is bent, the exterior plate The load is not applied intensively at the end position, and the end of the exterior plate is not damaged.

  In the pallets 1 and 1A according to the present invention, the reinforcing members 7 and 9 may be installed flush with the upper surface of the horizontal rail 3 of the pallet 1. Even in this case, it is possible to suppress damage to the pallets 1 and 1A when inserting the claw portions of the forklift by attaching the reinforcing members 7 and 9 that can be easily replaced even if they are broken.
