Then, if necessary, the coil material can be lifted by a crane and attached directly to the mandrel of the uncoiler, or it can be placed on a coil car using a crane and transported, and then lifted again by a crane and attached to the mandrel. However, in the past, when the coil material was placed horizontally as shown in Figure 11, it was troublesome to pass the chain through the hollow part of the coil material when lifting it with a crane, and the lifting height was large and time consuming. There was a problem that it was troublesome and the workability was poor. Further, when the coil material is placed vertically as shown in FIG. 10, there is a problem that the side surface of the coil material is not supported, resulting in poor stability and danger.

The present invention has been made in view of the problems of the prior art,

Our goal is to provide the following.

[Means for Solving the Problems] In order to achieve the above object, the coil material vertically placed pallet according to the present invention includes a frame-like pedestal having a pair of opposing side frames, and both ends supported by the side frames. and a pair of front and rear horizontal carrying rollers arranged at a predetermined interval, and a side frame at a position outside the pair of carrying rollers in the direction of separation, extending upwardly, and placed vertically on the horizontal carrying rollers. The coil material is provided with four side support arms that support both left and right sides of the coil material supported in the state.

Further, in claim (2), the two front side support arms and the two rear side support arms are respectively interlocked and tiltable about pivots, so that the arms can be held spread at any angle.

Further, in claim (3), the side support arm is screwed to a horizontal support shaft, which is a pivot supported between opposing side frames at both ends, to be integrated with the horizontal support shaft, and the side support arm is integrated with the horizontal support shaft, and the screw fastening position with respect to the horizontal support shaft is By changing the distance between the left and right side support arms, the distance between the left and right side support arms can be adjusted.

[Effect]

A pair of horizontal supporting rollers that support the arcuate outer peripheral surface of the coil material restrain the coil material in the front and back direction, and four sides that support both the left and right sides of the coil material, respectively, at positions outside the two supporting points in the direction of separation. The support arm prevents the coil material from falling sideways. The side support arm is opened at an arbitrary angle according to coil materials having different outer diameters, and the opened state is maintained. Coil materials with different coil widths can be supported by adjusting the spacing between the left and right opposing side support arms.
