Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a level-wound coil pallet which is lightweight and has excellent workability in packing and transportation.

[0002]

2. Description of the Related Art A level wound coil is a copper tube winding coil used for piping of an air conditioner, etc. When the level wound coil is supplied, a plurality of level wound coils are stacked and packed. It is placed on a flat square base having an insertion hole, is fixed by a steel band, and is transported and supplied by a truck or the like. Examples of the pallets include those made of wood or steel. For example, Japanese Utility Model Publication No. 62-11776, Japanese Utility Model Publication No. 62-25631,
It is known from official gazettes such as JP-B-55-27545. The structure of the pallet is required to have high strength, light weight, good workability in packing and transportation work, and can be transported safely without collapse of cargo during transportation.

However, conventional pallets made of wood are weak in strength, and if the strength is increased, the weight becomes heavy and the handling becomes inconvenient. In addition, steel pallets have high strength but are heavy and inconvenient to handle, so we use thin steel plates to reduce weight as much as strength allows. However, it is generally vulnerable to impacts such as collisions, and in particular, the insertion portion of the fork claws is easily damaged, resulting in dents and bends and poor durability. Furthermore, there was a problem that the pallet slipped during transportation by a truck and the level wound coil collapsed.

[0004]

SUMMARY OF THE INVENTION The present invention provides a level-wound coil pallet that is relatively lightweight, has high strength and durability, and that can prevent slippage during packaging and transportation. Is.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a hollow frame member is combined into an upper frame and a lower frame in a substantially quadrangular shape in two steps vertically, and a space is provided on a side surface for inserting a fork claw. And a reinforcing member in the shape of a box, and a jig that erects a column at the diagonal end of the side of the substantially quadrangle, an insertion hole through which a steel band is inserted, and the bottom surface of the corner of the substantially quadrangle. This is a level-wound coil pallet provided with projecting legs.

[0006]

As described above, since the present invention is made by combining the shape members which are all hollow square members, the weight is greatly reduced and the handling is easy as compared with the conventional thin steel plates. become. In addition, since a section made of hollow square bar is used as a reinforcing material in the part requiring strength, the increase in weight is slight and the strength can be increased where necessary.
It is possible to improve durability. Further, a jig for raising the support is provided compactly, and the insertion hole for passing the steel band is made to pass through the hollow portion of the hollow shape member to be combined, so that the space is saved and the work is facilitated.
And since the bottom surface of the pallet that touches the ground is provided with legs that project toward the ground, it does not slip and move during packing or transportation, and therefore workability is good,
In addition, the cargo can be safely transported without collapse.

The pallet of the present invention is optimally made by welding so that no protrusions are formed on the surface, but it can also be made by screwing bolts or nuts so that no protrusions are formed. Is. Further, as the material of the shape member, the steel material is most suitable from the viewpoint of cost, but an aluminum alloy may be used if the cost can be neglected. Furthermore, the cross-sectional shape of the hollow shape member may be a square shape, a rectangular shape, or a U-shaped shape member. The size and the number of hollow shape members to be used are appropriately selected according to the size and weight of the level wound coil.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an outline of a level wound coil pallet according to an embodiment of the present invention. In the figure, 1 is a frame made of hollow squares (40 × 2 in this example).
0x2 mm steel), and pallets are assembled using this hollow section for all parts. As shown in FIG. 1, the hollow frame member 1 is used to combine the upper frame 2 and the lower frame 3 in two steps, that is, in a substantially square shape when viewed from the top. A plan view seen from the upper surface is shown in FIG. 2, a side view is shown in FIG. 3, and a side view seen from the other is shown in FIG. As shown in FIGS. 2 to 4, the dimensions of the upper frame 2 and the lower frame 3 are quadrangles of 1140 mm × 1140 mm, and a space 4 for inserting a fork claw is formed on a side surface thereof. Compose into a box shape. The number of hollow members forming the upper frame and the lower frame can be appropriately increased or decreased. Next, a jig 6 for erecting a pillar that serves as a support when the level wound coil is placed is attached to the end portion located on the diagonal line of the side of the substantially quadrangle, and the hollow shape member 11 reinforced by the reinforcing material 5 is attached. The hollow portion of the hollow shape member 12 is used as an insertion hole 7 through which a steel band is inserted.

The upper frame 2 having the above-mentioned substantially rectangular shape
The reinforcing material 5 at the corners connecting the lower frame 3 and the lower frame 3 is projected from the lower surface of the lower frame 3 to form the leg portion 8. Depending on the weight, size, etc. of the legs to be placed, the legs 5 can also be made to project the reinforcing member 5 having the insertion hole 7 of the steel band if necessary. The hollow member 1 of the upper frame 2 may be used as the insertion hole 71 for the insertion hole 7 through which the steel band is inserted. Further, when assembling the pallet, it is optimal to weld the upper and lower surfaces so that no convex portions are formed on the upper and lower surfaces, but bolts and nuts or the like may be screwed if the convex portions are not formed on the surface. Furthermore, the end of the hollow frame member 1 may be covered with a lid to prevent rainwater and the like from entering. The level wound coil pallet of the present invention as described above has a weight of about 12 kg, which is significantly lighter than that of wood made of about 22 kg and steel plate made of about 25 kg. Further, the desired number of hollow shape members can be combined according to the required strength, and a reinforcing material can be inserted in the required portion, so that the structure can withstand the desired strength. Furthermore, since the projecting legs are provided on the lower surface of the pallet, it does not slip during packing or transportation.

Next, a method for packing level wound coils using the pallet of the present invention will be described. Figure 5
FIG. 3 is a schematic diagram illustrating a procedure for packing level wound coils using a pallet. First, as shown in FIG. A, a plastic bag 10 is set on a pallet 9, and a predetermined number of carton drums 13 wrapped with level wound coils and packed are stacked. Next, as shown in FIG. B, the whole stacked carton drums 13 are covered with a plastic bag 10 and taped,
Cover the outer circumference with the outer corrugated cardboard 14, then C
As shown in the figure, the support column 15 for supporting the carton drum is set up by using the support column jig 6 provided on the pallet. Then, as shown in FIG. 3D, the top plate 16 is covered, and the steel band 17 is passed through the steel band insertion hole 7 provided in the pallet to bind the pallet and the carton drum in a cross shape. The level wound coil packed in this way is transported to the destination by truck, etc., but the legs are protruding even during transportation, so the pallet does not slip and the cargo collapse can be prevented and it can be transported safely. it can.

[0011]

As described above, the level wound coil pallet of the present invention is lightweight, has high strength, is excellent in durability, and can prevent slippage during operation or transportation.
Since workability can be improved, it has a remarkable industrial effect.
