The cylinder 69L is moved to the left in FIG. 8 and stopped when the work lifting member 97L moves by a predetermined amount. The fixed amount is a work width input in advance, and the moving amount is detected by an encoder provided in the servo motor. Cylinder 69R in this state, by operating the 69L work up member 97R, and raised the 97L, the left L-shaped steel W ₁ is a claw upper portion of the workpiece push-up member 97L, the right section steel W ₁ workpiece pushing member 97R Is pushed up by the normal clamp upper surface.

In this state, the transport chain 7 is slightly moved to the right and stopped. As a result, a gap is generated between the L-shaped steel W ₁ and W _2. After the claw portion moved down the workpiece push-up member 97L spaced from the lower surface of the L-shaped steel L ₁ and actuated cylinder 69L, stopped by the detector 99L are moved to the work lifting member 97L to the left. As a result, the claw portions of the workpiece push-up member 97L is positioned in the gap formed between the L-shaped steel W ₁ and W _2.

[0051] Then, set the example timers, etc. in time, the workpiece push-up member increase allowed both ends of the L-shaped steel W ₁ is the left and right work causes 97L is back to the right the push-up member 97L, is sandwiched by the claw portions of the 97R You. In this state, the work lifting members 97L and 97R are
By moving it further up, it is transported to the transport chain 7.

The provision of the slide bar 103 on the support plate 41a is effective for an unstable work such as a round bar. Although the movement is slightly different for each work, a simple device is sufficient. The work lifting members 97L and 97R of the cylinders 69L and 69R can be exchanged corresponding to each work W.

The present invention is not limited to the above-described embodiment, but can be implemented in other modes by making appropriate changes. For example, although the present embodiment has been described with reference to an H-section steel, the present invention is not limited to this, and may be applied to various shaped steels, round bars, face bars, and the like. The work lifting members 97R and 97L are L-shaped. It may be shaped, for example, a flat plate may be provided with non-slip urethane rubber or the like on the upper surface.

Further, the left and right cylinders 69 serving as the lifters 5 are provided.
Considering the width of the work being laid horizontally, R and 69L should be such that the detector 99R provided on the work lifting member 97R detects the H-section steel W, and after moving X mm, designates to stop the left cylinder 69L. Is also possible.

Furthermore, the left and right cylinders 69R, 69L
It is only necessary that at least one of them moves, and the lifter 5 may be separately provided instead of being provided on the transport chain 7 and the lifter 5 may be slid by another drive mechanism. Also, the mechanism in which the material support rail 3 moves up and down has been described, but the effect is the same even if the chain side is moved up and down.

[0056]
