Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a pallet for transporting cargo using a forklift.

(Conventional technology) Conventional pallets use wood or synthetic resin as materials.
After transporting the cargo, the pallets are collected and used repeatedly.

(Problems to be Solved by the Invention) This conventional pallet has the trouble of having to retrieve the pallet over a long distance when it is transported to a long distance while loaded with cargo, and is also difficult to store when not in use. The drawback is that it requires a large amount of space for transportation.

On the other hand, since wood is used as a material for wooden pallets, it has been pointed out that the production thereof reduces the limited forest resources and accelerates their depletion. In addition, it is difficult to dispose of synthetic resin pallets after use because the technology for decomposing synthetic resins is still immature, and it is difficult to dispose of them after use. It was causing problems.

The present invention is inexpensive enough that it can be left at the destination without being collected even when transported to a long distance, saves space required for storing and transporting pallets when not in use, and uses wood as the material. The purpose is to provide a pallet that is not used and can be disassembled after use.

(Means for Solving the Problems) In order to achieve the above object, in the first invention as set forth in claim 1, fixed spacers made of cardboard are placed on both left and right sides of a paper receiving plate in parallel to each other. A paper expandable spacer bent into a bellows shape is connected to the fixed spacer, and a paper bottom plate is connected between the left and right expandable spacers. The curved slip material is fixed and a marker piece is made to protrude from the front edge of the bottom plate.

In the second invention described in claim 2,
Fixed spacers made of cardboard are fixed in parallel to both the left and right sides of the bottom of the paper receiving plate and the center of the bottom, and a telescopic spacer made of paper folded into a bellows shape is connected to the fixed spacers, and the left and right and a central expandable spacer are connected by a paper bottom plate, a slip material curved upward is fixed to the front edge of the cargo receiving plate, and a marker piece is made to protrude from the front edge of the bottom plate.

In the third invention described in claim 3,
A set of two cardboard fixed spacers is fixed in parallel to the bottom of the paper receiving plate in a symmetrical position, and each set is fixed by connecting a paper expandable spacer bent in a bellows shape to each fixed spacer. A paper bottom plate is connected between the expandable spacers connected to the spacers, and a slip material curved upward is fixed to the front edge of the receiving plate between each set of spacers, and the front edge of the bottom plate is Make the marker piece stick out.

(Function) The paper pallet of the first invention as set forth in claim 1 configured as described above has a structure in which a load is placed on the upper surface of the receiving plate, and a fork of a forklift is placed between the receiving plate and the bottom plate. Insert it, lift it upwards, and transport it.

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

When the tip of the fork of a forklift is inserted into the gap, the telescopic spacer, which had been contracted, is expanded vertically by the fork. At this time, the fork contacts the slip material, slides on its surface, and is inserted between the receiving plate and the bottom plate.

The expandable 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 slightly shifted from side to side with respect to the bottom plate, thereby preventing breakage of the fixed spacer.

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

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

The second invention and scope of claims set forth in claim 2, characterized in that the indicator piece indicates the fork insertion position to the operator, making it easy and reliable to confirm the fork insertion position, thereby preventing damage to the pallet due to incorrect insertion of the fork. In the paper pallet of the third invention described in item 3, the cargo is placed on the upper surface of the receiving plate in the same manner as in the first invention, and the fork of a forklift is inserted between the receiving plate and the bottom plate, and the pallet is lifted upward. and transport it.

In the paper pallet of the second invention, the expandable spacer and the fixed spacer provided at the center of the bottom of the load receiving plate support the load receiving plate from below, prevent the load receiving plate from curving downward due to the weight of the load, and prevent the load receiving plate from curving downward due to the weight of the load. Prevent collapse.

In the paper pallet of the third invention, a set of two fixed spacers provided at symmetrical positions on the bottom surface of the cargo receiving plate and an expandable spacer connected thereto support the cargo receiving plate from below, and support the receiving plate by the weight of the cargo. To prevent the load from collapsing by suppressing the downward curvature of the plate, and to ensure the insertion of the fork by securing a gap between the load receiving plate and the bottom plate.

(Example) An example will be described with reference to the drawings. In the embodiment shown in FIG.
A fixed spacer 9.9 made of laminated cardboard is glued in parallel to the left and right, and a telescopic spacer 4 made of paper bent into a bellows shape is connected to the lower part of the fixed spacer 9.

A paper bottom plate 2 is connected between the left and right expandable spacers 4, 4 to form a substantially rectangular cylinder.

A slip material 5 having an upwardly curved front end and a flat base is formed of synthetic resin, and the base is attached to the load receiving plate 1.
Glue it to the bottom surface of the front end 3.

The marker piece 15 is similarly made of synthetic resin, and its base is adhered to the upper surface of the front end of the bottom plate 2 to form a paper pallet.

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

In FIG. 4, when the cargo A is placed on the −L surface of the cargo receiving plate 1, the expandable spacer 4 contracts along the fold line in the length direction, creating a slight gap 8 between the cargo 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 telescopic spacer 4, which had been contracted, is expanded vertically by the fork B. At this time, the fork B comes into contact with the slip material 5, slides on its surface, and is inserted between the cargo receiving plate 1 and the bottom plate 2.

The expandable 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 slightly shifted from side to side with respect to the bottom plate 2, and prevents the fixed spacer 9 from breaking.

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

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

Note that it is preferable to perform a surface treatment such as lamination on the surface of the paper pallet of the present invention in terms of durability and waterproofness of the pallet.

In addition, especially when corrugated paper is used as the material for the cargo receiving plate 1, it is possible to effectively prevent cargo from collapsing.

Furthermore, if the surface of the marker piece 15 is colored with a fluorescent color or the like, it will be easier for the operator to confirm the insertion position of the fork.
Damage to the pallet due to incorrect insertion can be prevented.

As in the embodiment shown in FIG. 2, fixed spacers 9 are fixed in parallel to both left and right sides of the bottom surface and the center of the bottom surface of a paper cargo receiving plate 1, and paper sheets bent in a bellows shape are attached to the fixed spacers 9. By connecting the telescopic spacers 4 and connecting the left, right, and center telescopic spacers 4 with the bottom plate 2, the downward curvature of the cargo receiving plate 1 can be suppressed even when heavy cargo is placed, and the cargo can be prevented from collapsing. I can do it.

As in the embodiment shown in FIG. 3, two sets of fixed spacers 9 made of cardboard are fixed in parallel to each other in symmetrical positions on the bottom surface of the receiving plate 1 made of paper, and each fixed spacer 9 is folded into a bellows shape. By connecting the bent paper telescopic spacers 4 and connecting the paper bottom plate 2 between the telescopic spacers 4 connected to each set of fixed spacers 9, the horizontal spacing 10 between the telescopic spacers 4 can be designed to be small. Since the downward curvature of the cargo receiving plate 1 is suppressed to the minimum, it is possible to prevent the cargo from collapsing, and a sufficient gap can be secured between the cargo receiving plate and the bottom plate, so that the fork can be inserted reliably.

(Effects of the Invention) Since the present invention uses paper as a material, waste of wood can be avoided, and this is particularly noticeable when recycled paper is used as a material. Furthermore, after use, it can be disassembled and used again as recycled paper. By using paper as a material in this way, the price is low enough that even when transported over long distances, it can be left behind at the destination without being collected, and even when it is collected, it is expected to reduce transport costs because it is lightweight. can.

In addition, by interposing an expandable spacer between the 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 storing and transporting the pallet.
