Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire coil rack and a wire coil conveyance method, and in particular, in wire container coil transportation, unloading and damage of wire coils are prevented while unloading wire coils in an up-end state. In addition, the present invention relates to a wire coil rack and a wire coil conveying method capable of reducing transportation costs by facilitating fixing.

In the conveyance of a wire coil in which a wire material such as a copper wire or an aluminum wire is wound in a coil shape, container transportation is performed in which a plurality of wire material coils are loaded in a container and the container is loaded on a trailer or a ship for transportation.
Since each wire coil has a weight of about 2 t, a forklift, a crane, or the like is used for loading the wire coil into the container.

Here, in the container transportation of the wire coil, when the wire coil is transported into the container by a forklift or the like, the wire coil is damaged by the claw portion of the forklift or the wire coil is damaged by the contact between the wire coil and the inner wall of the container. May occur.
In container transportation of wire coils, the wire coils housed in the container must be connected with rope, wood, etc. against the floor or inner wall of the container in order to prevent damage to the wire coil due to rolling. There is a problem that the transportation cost increases because it is necessary to use and fix.

Here, in the present embodiment, the base column 7, the support column 8, the vertical column 9, the connection column 10, and the bottom upper column 12 are formed by square columns, and the base column 7, the support column 8, the vertical column 9, the connection The pillar 10, the bracing 11 and the bottom upper pillar 12 are made of wood.

Next, the conveyance method of the wire coil C using the wire coil rack 1 according to the present invention will be described with reference to the drawings.
FIG. 3 is an explanatory diagram showing the arrangement of containers. FIG. 4 is an explanatory view showing the arrangement of the Romanist forklift. FIG. 5 is a perspective view showing dimensions of the wire coil rack. FIG. 6 is an explanatory view showing the arrangement of the wire coil racks. FIG. 7 is an explanatory view showing accommodation of the wire coil in the wire coil rack. FIG. 8 is an explanatory view showing the movement of the wire coil rack by the high mast forklift. FIG. 9 is an explanatory view showing loading of a wire coil rack into a container by a Romanst forklift. FIG. 10 is a plan view showing the arrangement of the wire coil racks in the container.

In the present embodiment, the case where the wire coil C is loaded in the container S and transported will be described as an example.
In conveying the wire coil C, first, as shown in FIG. 3, a trailer T loaded with the container S is prepared, the container S is arranged on the platform P, and the rear door of the container S is opened.
Here, the internal dimensions of the container S are 5800 mm in the horizontal longitudinal direction, 2330 mm in the horizontal width direction, 2260 mm in the vertical direction at the entrance, and 2370 mm in the internal vertical direction.
And the Roman forklift F1 is arrange | positioned on the platform P from a ramp as shown in FIG.

Next, the wire coil C stored in the up-end state in the temporary storage place of the factory is accommodated in the wire coil rack 1.
Here, in this embodiment, the object is to transport 10 wire coils C by one container S, and the dimension in the direction in which the shaft extends as shown in FIG. Six wire coil racks 1a capable of accommodating a wire coil C1 having an outer diameter of 1300 to 1350 mm, a wire coil having an outer diameter of 1300 to 1350 mm shown in FIG. Four wire coil racks 1b capable of accommodating C2 are prepared. In this case, in principle, the wire coil rack 1a contains the wire coil C1 and the wire coil 1b contains the wire coil C2. Of the 10 wire coils C, three wire coils C2 are included. In the following cases, the wire coil C1 is also accommodated in the wire coil rack 1b. On the other hand, when there are five or more wire coils C2 among the 10 wire coils C, the wire coil rack 1a is replaced with the wire coil rack 1b in accordance with the number of wire coils C2. In addition, in this embodiment, although it is set as the said structure for the purpose of transporting ten wire rod coils C in one container S, the wire coil rack corresponding to the number of wire rod coils C1 and wire rod coils C2 corresponds. The configuration may be such that 1a and the wire coil rack 1b are prepared.

  Then, the wire coil racks 1 are arranged one by one under the platform P as shown in FIG. 6, and the wire coil C conveyed from the temporary storage by the high mast forklift F2 as shown in FIG. And accommodated in the wire coil rack 1. In this case, a wedge may be inserted between the wire coil rack 1 and the wire coil C in order to prevent the wire coil C from rattling in the wire coil rack 1.

Further, the wire coil rack 1 in which the wire coil C is accommodated is lifted onto the platform P by a high mast forklift F2, as shown in FIG.
Then, the wire coil rack 1 in which the wire coil C lifted on the platform P is accommodated is loaded into the container S by a Roman forklift F1 disposed on the platform P as shown in FIG. In this case, since the wire coil C is accommodated in the wire coil rack 1, damage to the wire coil C due to contact between the wire coil C and the inner wall of the container S or the like can be prevented.

  Here, the arrangement method of the wire coil rack 1 in the container S is, as shown in FIG. 10, a wire coil rack 1 a that accommodates the wire coil C <b> 1 and is arranged with the container S aligned in the longitudinal direction, The wire coil rack 1a that accommodates the wire coil C1 and the wire coil C1 or the wire coil C2 that are disposed so that the longitudinal direction of the container S is orthogonal to the width direction side of the wire coil rack 1a. Three sets of blocks including the rack 1b for the wire are arranged from the rear side in the longitudinal direction of the container S, and the wire coil rack 1b that accommodates the wire coil C1 or the wire coil C2 is disposed on the container S at the front side in the longitudinal direction of the container S. And are arranged so that their longitudinal directions are orthogonal to each other. In this case, in each block, the positions where the wire coil racks 1a arranged in the longitudinal direction coincide with the container S are arranged so as to be staggered at both ends in the width direction of the container S. Such an arrangement makes it possible to prevent the wire coil rack 1 from falling over in the container S.

In addition, the final arrangement of the wire coil rack 1 in the container S uses a width adjusting hand pallet.
Here, since the wire coil C is accommodated in the wire coil rack 1, it is only necessary to simply fix each wire coil rack 1 to the container S in the container C. The wire coil C can be easily loaded and unloaded.
After the loading of the wire coil rack 1 is completed, the rear door of the container S is closed, and the container S is transported to the destination by the trailer T.
In this case, in the container S, since the wire coil C is accommodated in the wire coil rack 1 in an up-end state, it is possible to prevent the wire coil C from being collapsed, damaged and deformed during transportation. .

Then, after the container S is transported to the destination, the wire coil rack 1 in which the wire coil C is accommodated is unloaded from the container S by a forklift or the like and stored in a warehouse or the like.
In this case, since the wire coil rack 1 is made of wood, it can be formed at a low cost and can be easily discarded. Therefore, the wire coil rack 1 can be disposable at the destination, and the transportation cost can be reduced by reducing the return cost of the wire coil rack 1.

As described above, according to the method for transporting the wire coil C according to the present invention, by using the wire coil rack 1, it is easy to unload and fix the wire coil C in the up-end state, thereby reducing the transportation cost. It becomes possible.
Although the embodiments of the present invention have been described above, various modifications can be made in the embodiments of the present invention.
For example, the arrangement and quantity of the wire coil rack 1 in the container S, the dimensions of the wire coil rack 1 and the like can be changed as appropriate.
