で問題があった。[Prior Art] In large-scale wall construction for nuclear power plant buildings and the like, there is a demand for assembling reinforcing bars safely and efficiently. Conventionally, when performing reinforcement work, reinforcing bars (hereinafter referred to as vertical reinforcements) are erected and fixed to insert bars planted in the foundation of a building, and reinforcing bars to be placed horizontally (hereinafter referred to as horizontal reinforcements) are marked on the surface. It is common to intersect with the f secondary reinforcement and then bind and fix these intersection points using a binding line. When arranging the above-mentioned horizontal reinforcements, several workers lift each tree of approximately 100 kg of horizontal reinforcements to a predetermined position by hand or a crane, and then tie them to the vertical reinforcements, but this method is inefficient and requires manual labor. When carrying out the work, the physical burden placed on the worker is large and there are problems in terms of safety.

6(A) is a partial side view showing the transfer device 20. FIG. The carry-in device 10 includes a drive device 13. Consisting of a sprocket 12, a chain 11, etc., at the start of work, the bundled reinforcing bars 18 groups are first placed on the chain 11, and the unbundled and released reinforcing bars 1 are divided into individual pieces and stopped. They are arranged in parallel up to the stopper 21. and the sixth
Due to the intermittent expansion/contraction operation of the butcher 22 in the direction of arrows 1a-1b shown in Figure (^), the reinforcing bars 1 are transferred one by one onto the conveying roller 31 by climbing over the stopper 21 and rolling down on the slope thereof. It will be done. It is assumed that each time the reinforcing bar 1 passes over the stopper 21, the driving device 13 is driven intermittently to sequentially feed the reinforcing bar 1 to the right in FIGS. 5 and 6(A). The conveyance roller 31 is mounted on a pedestal 32 (Fig. 5)
It is rotatably supported above and rotated by a drive device 34 via a chain 33 to move the replaced reinforcing bar 1a in the direction penetrating the plane of the paper in FIGS. 5 and 6(A). The outer peripheral surface of the transport roller 31 is lined with a synthetic resin material such as urethane rubber to prevent noise and slip. The movable conveyance roller device 40 shown in FIG.
3 is on the rail 62 in the axial direction of the reinforcing bar 1b (direction of arrow F)
It is constructed so that it can move forward and backward along the , and the setting position can be adjusted according to changes in reinforcing bar length. In addition, FIG. 6(B) shows the conveying roller device M40 on the distal side, the stopper truck 61, and the second stopper truck 63. That is, the second stopper truck 63 is provided with a stopper plate 64 that moves up and down as the cylinder 65 expands and contracts. Therefore, arrow F
The reinforcing bars 1b fed along the direction are stopped by the stopper truck 61 or by the raised position of the stopper plate 64a on the second stopper truck 63 (indicated by a broken line in the figure). That is, as shown in Fig. 2, when it is desired to manufacture a cross-shaped reinforcing bar in which adjacent reinforcing bars are alternately protruded and retracted in the left and right directions, the stopper carts 61 and 63 are alternately used to position the reinforcing bars in the longitudinal direction. Do the following.
