Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet for transporting a load using a forklift.

(Prior Art) Conventional pallets use wood or synthetic resin as the material,
After the parcel is transported, the pallet is collected and repeatedly used.

(Problems to be Solved by the Invention) In this conventional pallet, there is the trouble that the pallet must be collected for a long distance when the pallet is loaded and transported to a distant place, and is stored when not in use. There is a drawback that it requires a lot of space for transportation.

On the other hand, in the wooden pallet, since wood is used as a material, it has been pointed out that there is a problem that the limited forest resources for the production thereof are reduced and the depletion thereof is promoted. In addition, since synthetic resin pallets are currently undeveloped in synthetic resin decomposition processing technology, it is difficult to dispose of them after use, and they are used as industrial waste such as generation of harmful gas during incineration and disposal of undecomposed materials. It was causing problems.

INDUSTRIAL APPLICABILITY The present invention is low in price so that it can be left at the destination without being collected even when it is transported to a distant place, and it can save space required for storage and transportation of pallets when not in use, and wood as a material. It is an object of the present invention to provide a pallet that is not used and can be decomposed after use.

(Means for Solving the Problem) In order to achieve the above-mentioned object, in the first invention described in the first aspect of the invention, a fixed spacer made of cardboard is provided on the left and right sides of a paper-made receiving plate in parallel with each other. The paper-made telescopic spacers bent in a bellows shape are connected to the fixed spacers, and the paper-made bottom plates are connected between the left and right telescopic spacers. An anti-curved slip material is attached and a marker piece is projected on the front edge of the bottom plate.

In the second invention described in claim 2,
Fix the cardboard fixed spacers in parallel to the left and right sides of the bottom surface of the paper receiving plate and the center of the bottom surface respectively, and connect the paper expansion and contraction spacers bent in a bellows shape to the fixed spacers. The central stretchable spacer is connected by a bottom plate made of paper, a slip member bent upward is fixed to the front edge of the load receiving plate, and a marker piece is projected from the front edge of the bottom plate.

In the third invention described in claim 3,
Two sets of cardboard fixed spacers are fixed in parallel at the left and right symmetrical positions on the bottom surface of the paper receiving plate, and each fixed spacer is connected to a telescopic spacer made of a bent paper to fix each set. A paper bottom plate is connected between the expansion and contraction spacers that are connected to the spacers, and a slip material that is bent upward is fixed to the front edge of the load receiving plate between the spacers of each set, and the front edge of the bottom plate is The label piece is projected.

(Operation) In the paper pallet of the first invention described in claim 1 configured as described above, the load is placed on the upper surface of the load receiving plate, and the fork of the forklift is placed between the load receiving plate and the bottom plate. Insert it, lift it up and carry it.

When the load is placed on the upper surface of the load receiving plate, the expandable spacer is contracted along the fold line, and the entire paper pallet becomes flat, leaving a slight gap between the load receiving plate and the bottom plate.

When the tip of the fork of the forklift is inserted into the above-mentioned gap, the contracted expandable spacer expands vertically due to the fork. At this time, the fork comes into contact with the slip member and slides on its surface, and is inserted between the load receiving plate and the bottom plate.

The expandable / contractible spacer secures a gap between the load receiving plate and the bottom plate, and at the same time allows the load receiving plate to be displaced to the left and right with respect to the bottom plate, thereby preventing breakage of the fixed spacer.

The fixed spacer secures a gap between the load receiving plate and the bottom plate and ensures the insertion of the fork.

The bottom plate allows the fork to slide smoothly on the bottom plate and allows the fork to be smoothly inserted even when the ground is uneven, such as concrete, and protects the fork from wear.

The marker piece indicates to the operator the fork insertion position and confirms the fork easily and surely to prevent damage to the pallet due to incorrect insertion of the fork.

The paper pallet according to the second invention described in claim 2 and the third invention described in claim 3 is similar to the above-mentioned first invention in that the load is placed on the upper surface of the load receiving plate. , Insert the fork of the forklift between the load receiving plate and the bottom plate, lift up and transport.

In the paper pallet according to the second aspect of the invention, the expandable spacer and the fixed spacer provided in the central portion of the bottom surface of the load receiving plate support the load receiving plate from below and prevent the load receiving plate from being bent downward due to the weight of the load. Prevent collapse.

In the paper pallet according to the third aspect of the present invention, a set of two fixed spacers provided at symmetrical positions on the bottom surface of the load receiving plate and a telescopic spacer connected to the fixed spacers support the load receiving plate from below and receive the load depending on the weight of the load. The downward bending of the plate is suppressed to prevent the load from collapsing, and the gap between the load receiving plate and the bottom plate is secured to ensure the insertion of the fork.

(Example) An example will be described with reference to the drawings. In the embodiment shown in FIG. 1, on the lower surfaces on both left and right sides of the paper-made load receiving plate 1,
Fixed spacers 9 and 9 formed by stacking thick papers are adhered in parallel to each other on the left and right, and a stretchable spacer 4 made of paper which is bent in a bellows shape is connected to a lower portion of the fixed spacer 9.

A paper-made bottom plate 2 is connected between the left and right expandable spacers 4 to form a substantially rectangular tubular body.

A slip member 5 having a front end portion bent upward and a flat base portion is made of synthetic resin, and the base portion is formed into the load receiving plate 1 described above.
It is adhered to the bottom surface of the front end portion 3.

Similarly, the marking piece 15 is made of synthetic resin, and its base portion is bonded to the upper surface of the front end portion of the bottom plate 2 to form a paper pallet.

Therefore, the paper pallet of the first invention described in claim 1 constructed as described above is shown in FIGS.
As shown in the figure, the load A is placed on the upper surface of the load receiving plate 1, the fork B of the forklift is inserted between the load receiving plate 1 and the bottom plate 2, and is lifted and conveyed upward.

In FIG. 4, when the load A is placed on the upper surface of the load receiving plate 1, the expandable spacer 4 shrinks along the lengthwise fold line, leaving a slight gap 8 between the load receiving plate 1 and the bottom plate 2. The entire paper pallet becomes flat.

In FIG. 5, when the tip of the fork B is inserted into the gap 8, the contracted expandable spacer 4 is expanded vertically by the fork B. At this time, the fork B contacts the slip member 5, slides on the surface thereof, and is inserted between the load receiving plate 1 and the bottom plate 2.

The expandable / contractible spacer 4 secures a gap 8 between the load receiving plate 1 and the bottom plate 2 and at the same time allows the load receiving plate 1 to be displaced to the left and right with respect to the bottom plate 2 to prevent the fixed spacer 9 from being broken.

The fixed spacer 9 secures the gap 8 between the load receiving plate 1 and the bottom plate 2 and ensures the insertion of the fork B.

The bottom plate 2 allows the fork B to slide smoothly on the bottom plate 2 and allows the fork B to be smoothly inserted even when the ground such as concrete is uneven, and protects the fork B from abrasion.

The surface of the paper pallet of the present invention is preferably subjected to surface treatment such as laminating in terms of durability and waterproofness of the pallet.

In addition, if corrugated paper is used as the material of the load receiving plate 1, the load collapse can be effectively prevented.

If the surface of the marker piece 15 is markedly colored such as fluorescent color, it is easy for the operator to confirm the fork insertion position and damage to the pallet due to erroneous insertion can be prevented.

As in the embodiment shown in FIG. 2, fixed spacers 9 are fixed in parallel to the left and right sides of the bottom surface of the paper-made load receiving plate 1 and the central portion of the bottom surface, and the fixed spacers 9 are bent in a bellows shape. By connecting the expandable spacers 4 and connecting the expandable spacers 4 on the left and right sides and the center by the bottom plate 2, it is possible to prevent the load from collapsing and prevent the load from collapsing even when a heavy load is placed. You can

As in the embodiment shown in FIG. 3, two sets of two fixed spacers 9 made of cardboard are fixed in parallel to each other at the symmetrical positions on the bottom surface of the paper-made load receiving plate 1 and folded in a bellows shape on each fixed spacer 9. By connecting the bent paper expandable spacers 4 and connecting the paper bottom plates 2 between the expandable spacers 4 connected to the fixed spacers 9 of each set, it is possible to design the lateral distance 10 between the expandable spacers 4 to be small. Since the downward bending of the load receiving plate 1 is minimized, collapse of the load can be prevented, a sufficient gap can be secured between the load receiving plate and the bottom plate, and the fork can be reliably inserted.

(Advantages of the Invention) Since the present invention uses paper as a material, it is possible to avoid waste of wood, and this is particularly remarkable when recycled paper is used as a material. Further, after use, it can be decomposed and reused as recycled paper. By using paper as the material in this way, the price is low enough to leave it at the destination without collecting it even when it is transported to a distant place, and it is also lightweight when recovering it, so it is expected to reduce the transportation cost. .

In addition, since the expansion spacer is interposed between the load receiving plate and the bottom plate, the pallet can be compressed flat when not in use, which greatly contributes to saving the space required for storage and transportation of the pallet.
