However, in the above-mentioned conventional storage rack, the insertion work and the removal work of the interstitial material 33 must be performed by the hands of the workers, which is extremely troublesome.
The work is done at a higher place as they are piled up, so the risk is high. Further, as the length of the long member 32 becomes longer, the number of gap members to be set also increases and the work amount increases. Further, since the work of the worker is required at the time of loading and unloading, the work passage 34 must be provided in the accommodation space, and the storage rate of the long material is reduced accordingly, and the storage amount of the long material that can be stored is small. There was a problem of becoming.

The invention according to claim 1 of the present invention solves the above problems, and provides a long material storage shelf which can automatically and safely carry in and out long materials and can improve the storage rate. With the goal.

[0005]

In order to achieve the above object, the invention according to claim 1 of the present invention is such that support columns are provided at the side portions of the accommodation space at predetermined intervals along the longitudinal direction of the elongated member. Standing upright,
A fixed support means for holding the long material is arranged at the lowest stage of the accommodation space, and the base end is rotatably supported by the support column around a horizontal axis to project toward the accommodation space and retain the long material. A plurality of possible rotation support levers are provided at predetermined intervals in the up-down direction, and these rotation support levers include rotation restriction means for restricting downward rotation from a support position protruding toward the accommodation space,
Urging means for urging the rotation support lever to rotate upward,
At the retracted position of the rotation support lever that is rotated upward from the accommodation space, the floating lever that projects toward the accommodation space and the rotation lever that restricts the rotation of the idler lever only downward from this protruding position. The interlocking means is provided, and when the long material is lowered and carried in along the accommodation space, the floating lever is pivoted downward, and the pivotal support lever is pivoted downward and supported by the interlocking means. So that the floating lever is restricted from rotating upward by the long member that is projected to the position and carried on the lower rotary support lever or the fixed support means so that the rotary support lever is held at the support position. It is configured in.

According to the above construction, when a long material is carried into the accommodation space from above by using a crane or the like, the projecting floating lever is pivoted downward on the upper stage side of the empty load and is rotated via the interlocking means. The moving support lever is lowered while being rotated to the support position, and the idle lever and the rotation support lever after passing are returned to the original position by the biasing means. When it is mounted on the fixed support means or the rotation support lever at the lowest position, the upper floating lever is locked by the long member, so that the rotation support lever at the support position retracts upward. Instead, the long material to be carried in next is mounted on the rotation support lever. In this way, the long material is sequentially loaded and mounted on the rotation support lever from the lower side upward, and the long material is automatically accommodated at a predetermined pitch in the vertical direction according to the pitch of the rotation support lever. You can In addition, by carrying out sequentially from the upper long material, the empty supporting lever is rotated upward by the biasing means, and the floating lever is returned to the position where it projects into the accommodation space. Further, when the long material below the upper material is carried out upward, the upper floating lever is separated from the interlocking means and freely rotated upward from the projecting position, so that it can be easily carried out.

Therefore, it is possible to automatically carry in and carry out the long material without the trouble of inserting the gap material into each long material as in the conventional case.
