Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement of a packing structure for packing a package such as a copper coil winding coil, which is mainly called a level wound coil.

[Prior Art] As a technique for stacking level wound coils and transporting them in a packaged state, the applicant has already filed a practical application.
We are trying various proposals in 8-108113.

The pallet 1 in the above technique is as shown in FIG.
Two crosspiece members 1a arranged parallel to each other at both ends, a core member 1b arranged in the center of these crosspiece members 1a and having a groove 1b1 through which the band 2a is inserted in the longitudinal direction of the upper surface, An upper plate 1c attached to the upper surface of the crosspiece member 1a in a direction orthogonal to the member 1a,
It is composed of a cross member 1a and a lower plate 1d which is attached to the lower surface of the cross member 1a so as to have a gap S through which the band 2a is inserted at the center in the orthogonal direction.

The level-wound coil is laminated on the pallet 1 configured as described above, which is put in a carton sleeve and covered by the canopy 3a to be packed. As shown in FIG. Bands 2a and 2b are tied in a cross shape. One of the two bands 2a and 2b, 2a
Is inserted from the package 3 into the groove 1b1 and bound, and the other one 2b is inserted from the package 3 into the gap S and bound. A support column 4 for reinforcement is attached to the outer peripheral surface of the package 3 at a position where the bands 2a and 2b are applied.

By the way, in such a packing structure, even if the packing object 3 in which the level wound coils are stacked is the band 2a.
・ 2b is tied to the pallet 1 so that it is a rigid body as a whole. Therefore, even if the vehicle is tilted to some extent when transported by a forklift or the like, it is possible to considerably prevent the deviation of the center of gravity between the stacked level wound coils.

[Problems to be solved by the invention] However, in order to bind a large amount of packing items 3 such as a level wound coil to the pallet 1 and make them into a so-called one rigid body, the bands 2a and 2b are applied with considerable force. Must be tightened. Also, when the package 3 is tilted and a load is applied to one side during transportation by a forklift, etc.,
On the other hand, a large force acts in the direction in which the band 2a is lifted and pulled. When this force acts on the groove 1b1, there is a problem that a force higher than the normal tightening force of the band 2a acts on the upper plate 1c immediately above the groove 1b1 and damages it. As a means for solving this, for example, the upper plate 1c
It is conceivable to use a considerably thick material, but this still has a problem in that it is costly.

In this invention, there are problems in that the upper plate is damaged due to the synergistic effect of the tightening force of the band and the tensile force when tilted, and the cost is also a problem.

[Means for Solving Problems] In the packing structure of the present invention, conventionally, a groove having an upward opening is formed on the upper surface of the core material, whereas a groove having an downward opening is formed on the lower surface. Moreover, the depth and width of the groove are made larger than the dimensions of the band, and the band is inserted into the groove for packing.

[Action] The tightening force of the band and the tensile force when tilted are applied directly to the core material without directly acting on the upper plate, so the core material and upper plate will be damaged even if a considerable tensile force acts on the band. It is possible to improve the durability of the pallet without causing it.
Moreover, since the material is the same as the conventional one, the cost can be sufficiently satisfied.

[Embodiment] A first embodiment of the present invention will be described below with reference to FIG. The same components as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted.

The pallet 10 has two core members 10a arranged at both ends in parallel with each other, and a core member having a groove 10b1 formed in the center of the cross members 10a and through which the band 2a is inserted in the longitudinal direction. 10b, an upper plate 10c mounted on the upper surface of the crosspiece member 10a so as to be orthogonal to the crosspiece member 10a, and a crosspiece having a gap S which is orthogonal to the crosspiece member 10a and has the band 20b inserted at the center in the orthogonal direction. The lower plate 10d is attached to the lower surface of the member 10a.

The canopy 3b is placed on the pallet 10 configured as described above.
A circular package 3 is placed. In order to integrate the package 3 with the pallet 10, the band 2a
Tie 2b in a cross shape. In this case, one band 2a is inserted into the groove 10b1 and tightened. The other band 2b is inserted into the gap S and is tightened. Further, a binding band 16 made of, for example, iron is fastened to a substantially central portion in the height direction of the package 3, and the support column 4 is restrained by the package 3. That is, the support 4 and the package 3 are, as it were, a rigid body.

A groove 10e, which is deeper than the thickness of the bands 2a and 2b, is formed at the winding positions of the bands 2a and 2b on the end surfaces of the core material 10b and the upper plate material 10c that form the pallet 10. There is. And band 2a
2b is wound around this groove 10e in a tensioned state.
In this state, the bands 2a and 2b are wrapped around the pallet 10 without projecting to the outside of the outer peripheral surface of the pallet 10, so that the bands 2a and 2b are not caught by other objects during transportation or the like, and therefore are not broken. Has become.

In the case of the packing structure as described above, for example, when carrying by a forklift or the like, the bands 2a and 2b are
The tightening force of the band 2a and the tensile force of the band 2a generated when the package 3 is tilted are applied directly to the core material 10b without directly acting on the upper plate 10c, so that a considerable tensile force acts on the band 2a. However, the durability of the pallet can be improved without damaging the core material 10b or the upper plate. Moreover, since the material is the same as the conventional one, the cost can be sufficiently satisfied. Of course, the other band 2b
Is inserted into the gap S formed in the center between the lower plates 11d, the band 3b may be bent when the package 3 is tilted.
A large tensile force acts on the crosspiece member 10a, so that the crosspiece member 10a can withstand it sufficiently.

Further, in this embodiment, since the package 3 and the support column 4 are tightened and restrained by the binding band 16 so that they become an integral rigid body, the package 3 tilts during transportation, etc. Even when an unbalanced load is applied to the support column 4, it is possible to solve the problems such as buckling and bending of the support column 4 that have occurred conventionally.

In addition, in the above-mentioned embodiment, the package 3 in which level-wound coils are laminated has been described as an example, but it may not be laminated, and needless to say not a level-wound coil.

Further, FIG. 2 shows a modified example of the present invention, in which the package 13 is formed in a quadrangular prism shape, and other configurations and effects are similar to those of the above-mentioned embodiment.

[Effects of the Invention] In the packing structure of the present invention, since the core member arranged between the beam members at both ends is provided with the groove that opens downward, the band can be inserted into the groove for packing. As a result, the tightening force of the band and the pulling force when tilted do not directly act on the upper plate, and are first applied to the core material.
Therefore, even if a large tensile force acts on the band due to the package being tilted or the like, the durability of the pallet can be improved without damaging the upper plate. In addition, since a groove deeper than the thickness of the band and wider than the band is formed at the position where the band is wound around the upper plate, the core material, and the crosspiece member, the band does not protrude beyond the outer peripheral surface of the pallet and can be transported. The band does not get caught in something else. Therefore, the band is prevented from being abruptly broken and the collapse of the load can be effectively prevented. Further, since the entire band is housed inside the groove, it does not stick out from the outer peripheral surface of the pallet, and even when a plurality of pallets are stored in a warehouse or loaded on a ship or the like, each pallet is transported. The outer peripheral surfaces of the can be arranged in an orderly manner in a state of being in close contact with each other. For this reason, the storage space is not wasted, and the movement of the pallets is reliably restrained by the close contact between the outer peripheral surfaces of the pallets, and as a result, the displacement of the pallets due to the shaking of the ship during transportation is avoided. , Damage to the band is more reliably avoided. Further, according to the above configuration, since the pallet is substantially reinforced without increasing the number of members constituting the pallet as compared with the conventional one, the manufacturing cost of the pallet can be sufficiently satisfied.
