DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coil material pallet used when a coil material is carried by a forklift.

[0002]

2. Description of the Related Art Conventionally, wound steel sheets, wound wire materials, roll paper,
A pallet 101 used when a coil material such as a wound carpet is transported by a forklift is provided with a coil material receiving base 103 on a pallet body 102 as shown in FIG. Are formed at the upper part of the curved portion 103a having a curvature R corresponding to the shape of the coil material A. In the pallet body 102, fork insertion holes 102a, 102a into which forks (not shown) of a forklift are inserted.
Are formed.

However, the outer diameter of the coil material A to be conveyed by a forklift using such a pallet 101 is as follows:
It is not always constant, and each time a coil material A having a different outer diameter is conveyed, the coil material A having a curved concave portion 103a having a curvature corresponding to the outer diameter is formed. Had to be replaced. Therefore, as many as the number of types of the coil material A to be conveyed,
01 had to be prepared and it was troublesome.

[0004] Therefore, as a pallet on which a plurality of types of coil materials having different outer diameters can be placed on one pallet, an arm body having a pair of arc-shaped plates is attached to a base of the pallet via a shaft (pin). There has been proposed a structure in which three shaft holes are provided in a base of a pallet so that a shaft can be inserted into any one of the shaft holes according to the size of the coil material to change the interval between the arm bodies (for example, there is proposed) And Japanese Utility Model Application Laid-Open No. 61-22724).

[0005]

However, in such a pallet, a plurality of types of coil materials having different outer diameters can be placed, but if the outer diameters of the coil materials are different,
Each time, it is necessary to remove the shaft from the shaft hole of the arm main body and replace it with another shaft hole corresponding to the outer diameter of the coil material to be conveyed, which is quite troublesome. Further, since the relationship between the shaft and the shaft hole is used to correspond to coil materials having different outer diameters, there is a restriction on the outer diameter of the coil material that can be handled.

It is an object of the present invention to provide a pallet for a coil material which can place and transport the coil material without being restricted by the outer diameter of the coil material.

[0007]

According to a first aspect of the present invention, there is provided a pallet for a coil material which is provided when a forklift of a forklift is provided below a pallet body on which the coil material is placed, and which is used to transport the coil material by the forklift. And
A pedestal on which the coil material is supported is provided on the pallet main body via an elastic body, and a pair of abutting members abutting so as to sandwich the coil material from both sides, the coil material is lowered by lowering the pedestal. It is connected to the cradle so as to be displaced in the holding direction. Here, the contact member includes a contact member provided with a receiving pad (for example, a rubber pad) on a surface side that sandwiches the coil material from both sides. Therefore, the contact member includes not only a case where the coil material is directly sandwiched from both sides without the receiving pad, but also a case where the coil material is sandwiched from both sides via the receiving pad.
In addition, the elastic body includes a rubber with high elasticity in addition to a coil spring, a disc spring, and the like.

According to the first aspect of the present invention, when the coil material is placed on the pedestal, the elastic member provided between the pedestal and the pallet body is compressed, and the amount of compression of the elastic member increases as the amount of compression increases. The cradle descends. As the cradle descends,
The pair of abutting members are displaced in the direction of sandwiching the coil material, sandwiching the coil material from both sides, and holding the coil material.

Therefore, even if the outer diameter of the coil material changes, only the position at which the pair of abutting members sandwich the coil material changes.
The coil material is held without difficulty. In particular, since the positions of the pair of abutting members change continuously, there is no restriction on the outer diameter of the coil material, and within the movable range of the abutting member, regardless of the outer diameter of the coil material. Can be pinched.

According to a second aspect of the present invention, a support base may be provided on the upper surface of the pallet body, the support base being in contact with the pedestal when the elastic body is compressed and the pedestal is lowered. . Here, the degree to which the elastic body is compressed is such that it is not fully compressed.

[0011] According to this configuration, the descending amount of the pedestal is regulated to a fixed amount by contacting the support when the pedestal descends, and the elastic body is unnecessarily large due to excessive descending of the pedestal. Load does not work.

According to a third aspect of the present invention, the pallet body includes a stopper for restricting the pair of abutting members from being displaced away from each other when the coil material is not placed on the receiving table. It is desirable to have a member.

With this configuration, even when the coil member is not placed on the receiving table, the stopper member prevents the pair of contact members from being displaced away from each other by their own weight. Thus, the standby state where the coil material can be placed at any time is maintained.

According to a fourth aspect of the present invention, the support base is
It is preferable that a spacer member that adjusts a descending amount of the pedestal is provided on an upper side.

In this case, if the type of the coil material is different, the unit weight or the like is also different. Therefore, by adjusting the maximum descending amount of the pedestal according to the type of the coil material, the elastic body is lowered by descending the pedestal. It is avoided that a large burden is imposed on the user.

According to a fifth aspect of the present invention, there is provided a pallet for a coil material which is provided when a forklift of a forklift is provided below the pallet body on which the coil material is placed, and which is used to transport the coil material by the forklift. A pedestal supported by the pallet body so as to be able to move up and down, a spring member provided between the pedestal and the pallet body to bias the pedestal in a direction away from the pallet body; A pair of abutting members provided so as to be located on both sides and capable of abutting on the coil material; and a pair of abutting members provided between the pedestal and the abutting member. And a linking means for displacing in the direction of the movement.

In this way, as the cradle descends,
Since the linking means displaces the pair of abutting members in a direction approaching each other, the abutting members approach and abut the coil material from both sides of the pedestal, and the coil material is sandwiched between them.
Therefore, even if the outer diameter of the coil material changes, it is not necessary to change the pallet receiving stand, and a plurality of types of coil materials having different outer diameters can be placed on one pallet.

According to a sixth aspect of the present invention, the linking means includes a rod member having an upper end connected to the receiving base and extending in a vertical direction, and the contact member provided at one end and the rod at the other end. "Ku" rotatably connected to the lower end of the member
And a pair of bell cranks, each having an intermediate portion rotatably supported by the pallet body, and a rotation exceeding a certain angle in a direction in which the contact member is separated is restricted. Is desirable.

With this arrangement, the rod member integrated with the pedestal is also lowered with the lowering of the cradle, and the bell crank is rotated in the direction of bringing the contact members closer to each other with the lowering of the rod member. Is pinched. Also, if rotation beyond a certain angle in the direction in which the contact member separates is regulated,
When the coil material is not placed, the standby state where the coil material can be placed at any time is maintained.

Next, a case where the coil material A is transported using the coil material pallet 1 will be described.

When the coil material A is placed on the pedestal 8, the coil spring 9 provided between the pedestal 8 and the pallet body 2 is compressed by the weight of the coil material A, and the pedestal 8 is lowered. . The lowering of the cradle 8 causes the pair of holding members 12A, 12B to rotate about the rotation shaft members 15A, 15B as rotation centers, so that the contact members 14A, 1B are rotated.
4B comes to be displaced in the direction of sandwiching the coil material A, and the coil material A is sandwiched from both sides by a force corresponding to the weight of the coil material A by both contact members 14A and 14B. Thereby, the coil member A is securely held by the two contact members 14A and 14B.

If the coil material A is held by such holding, even if the outer diameter of the coil material A changes, the holding position of the coil material A by the contact members 14A and 14B of the pair of holding members 12A and 12B changes. Only, the coil material A is reasonably held.

In this case, even if the cradle 8 attempts to descend excessively due to the weight of the coil material A, the maximum descending amount is restricted by the lower surface of the cradle 8 abutting against the support bases 4A and 4B. An unnecessarily large load does not act on the coil spring 9 due to excessive lowering of the receiving stand 8.

Even when the coil material A is not placed on the receiving table 8, the two holding members 12A, 12B are provided with a certain distance between the contact members 14A, 14B.
B bell cranks 13A and 13B are stopper members 21
A, 21B, the contact members 14A, 14B of the pair of holding members 12A, 12B are restricted from being further displaced away from each other by the contact, and the coil member A can be placed on standby. The state is always maintained.
