BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet for transporting a plurality of thin metal plates in a stacked state.

[0002]

2. Description of the Related Art Conventionally, when thin metal plates are stacked and transported outside the factory without damage, the vertical and vertical
A box made according to the horizontal size was prepared, metal sheets were stored in the box stacked and transported in the packed state. Or, make a pallet according to each size with wood etc., fix the laminated metal plate on it and transport it, and transport it without damage even if it vibrates during transportation on the cargo bed of transportation equipment such as a truck Measures have been taken to do so. However, in this case, it was necessary to create a pallet according to the size, so it was difficult to use it repeatedly during multi-product production, and a large number of spare pallets had to be prepared according to the product type. The problem was that

As an invention for solving this problem, there is, for example, Japanese Patent Laid-Open No. 9-328162. This is a container including an upper lid with a cushioning member on the lower surface, a bottom frame fixed on the pallet with a bottom plate, left and right fixed side plates, and a movable side plate on the front side, wherein the movable side plate is a dividing line. The upper half of the movable side plate can be inverted to the outside of the container by
A groove member that is fixed to the inside of the left and right fixed side plates and that includes a pair of vertical grooves that face each other, and a lower end portion that is fixed on the bottom plate and that is inserted into the vertical groove pair supports the lower end portion of the contained object. And a support member.
However, in the case of the present invention, when the thin plate to be conveyed is rectangular or close to it, it is sufficient to solve the above problems, but the target material is, for example, a triangle, a trapezoid, or a trapezoid.
In the case of an elliptical shape, the end faces of the laminated thin plates cannot be sufficiently restrained, and it is conceivable that the stacks of the thin plates are misaligned to cause a load collapse during transportation and damage.

Further, in Japanese Unexamined Patent Publication No. 9-30526, as a pallet for transporting thick metal plates, a plurality of pairs of columns are erected perpendicularly to both sides in the width direction of a pallet substrate having a rectangular planar shape. , Every time a metal slab is stacked on the pallet board, a friction restraint plate having a notch corresponding to the support is placed on the pallet substrate, and the support other than the vertical movement is restrained by the support so that This is to prevent the metal thick plate from sliding due to shaking or the like. However, in this case, since there is a gap between the metal thick plate and the support, when a large vibration is applied during transportation, such as when the weight of the metal plate is small and the frictional force is not sufficient, the metal plates slide and are damaged. There is a problem that the cost of packing and transporting increases as a result, since many spares of pallets and friction restraint plates must be prepared according to the size when producing a wide variety of products.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. FIG. 1 shows an embodiment of the present invention. The present invention relates to a pallet for transporting a plurality of thin metal plates 1 in a stacked state. The pallet surface 2 has a two-layer structure with a space in between, and is made of a metal plate or a resin plate. At least 20 or more holes are formed so that the holes penetrate the upper and lower two layers. A support rod 3 having an eccentric insertion pin 5 to be inserted into the round hole fixes the outer periphery of the thin metal plate 1 which is the object to be conveyed, and the support rod 3 is bound by a hoop 4 around the support rod 3. I am trying. As a result, the thin metal plate 1 can be transported without the load collapse during the transportation.

For example, as shown in Japanese Patent Application Laid-Open No. 9-328162, when attempting to restrain the thin metal plates 1 laminated by partition plates, the partition plates can restrain at most four directions of the thin metal plates. Since it is not necessary, the thin metal plate may have a rectangular shape, but depending on the shape of the thin metal plate 1, it is possible that the thin metal plate may rotate in a horizontal plane during conveyance in the partition plate to cause a load collapse, and a laminated material which is a material to be conveyed. If a gap with the partition plate is generated due to thermal expansion or a slight change in the shape of the formed thin metal plate 1, the laminated thin metal plates 1 cannot be sufficiently restrained, and vibrations during transportation cause flaws in the thin plates. .

As in the present invention, the support bar 3 is fixed to the pallet surface 2 by the eccentric insertion pin 5, so that if the support bar 3 is rotated, the size of the plurality of laminated thin metal plates 1 is increased. Can be easily fixed without any gap,
By increasing the number of support rods, not only rectangular but also polygonal / oval and other thin metal plates having a free-form surface can be sufficiently restrained. Further, if the number of round holes on the surface of the pallet is increased, the insertion position of the support rod 3 can be freely changed depending on the shape of the thin metal plate 1, so that the degree of freedom is increased. Again hoop 4
As a result, the support rod 3 is always pressed against the thin metal plate 1 with an appropriate force, so that it can sufficiently withstand vibration during transportation.

Although the pallet according to this embodiment has a structure in which the pallet surface 2 having a two-layer structure is provided on the pallet substrate 10, the pallet substrate 10 is provided with the groove 11 so that the forks of the forklift can be easily inserted. The pallet board 10 may be provided as needed, and the pallet using the forklift is designed so that it can be easily loaded on a truck or the like. In addition, for the sake of completeness,
It is effective to insert a cushioning material such as rubber, plastic, or wood between the supporting rod 3 and the laminated thin metal plates 1 or between the upper surface of the pallet and the metal plate 1. As shown in FIG. 3, instead of sandwiching the cushioning material separately, the cushioning material 6 is used to support the support rod 3
The surface of the elastic body may be covered to serve as a support rod on the surface of the elastic body. Further, as shown in FIG. 4, the pallet and the thin metal plate 1 may be bound by a hoop 4 in the vertical direction.

FIG. 2 is a sectional view of a pallet according to the present invention. Here, a groove 7 is provided on the upper surface of the pallet, and when the pallet is unloaded, the claws of the forklift are formed together with the groove 7 and the thin metal plate 1 laminated. By inserting it in between, the unloading work can be done easily. When the round holes 8 are arranged in a grid pattern or a zigzag pattern as shown in FIG. 5, the center line of the round holes is inclined with respect to the side of the pallet as shown in FIG. The degree of freedom in shape is increased. Further, as shown in FIG. 7, it is possible to stack the pallets through the removable columns 9 to increase the space efficiency.
This pallet can be used repeatedly as a returnable box.

According to the present invention, it is possible to provide a pallet for laminated thin metal sheets which can be applied to the transportation of thin metal sheets of various shapes and sizes and which can be repeatedly used. Can contribute.
