  In the second invention, the reinforcing bars can be separated downward from the receiving openings one by one with a simple structure.

  The reference numerals in the parentheses indicate the correspondence with specific means described in the embodiments described later.

  As described above, according to the reinforcing bar distribution device of the present invention, the mesh bar manufacturing process can be labor-saving easily and inexpensively.

It is a whole side view of a distribution device showing one embodiment of the present invention. It is a whole top view of a distribution device. It is a side view of a jig for mesh production, and a supply mechanism located on it.

  FIG. 1 shows a side view of the dispensing apparatus, and FIG. 2 shows a plan view thereof. The accommodation mechanism H which comprises a distribution apparatus is provided in the longitudinal direction of the reinforcing bar f hold | maintained at this in several positions (three places in this embodiment, FIG. 2). Each accommodation mechanism H has the same structure and includes a gantry 1. The gantry 1 is an assembly of angle members. On the gantry 1, a vibration table 2 as an arrangement means is placed. The vibration table 2 has four lower corners supported on the gantry 1 by coil springs 21, and a vibration motor 22 is attached to a mounting seat 23 on the lower surface of the table in a predetermined posture.

  An accommodation piece 3 is fixed to the upper end of the front surface (right surface in FIG. 1) of the gantry 1. The accommodation piece 3 is formed by forming an accommodation opening 31 as an accommodation portion in the center of the long plate, and is formed into a substantially U shape as a whole. The accommodation opening 31 is opened upward, and its side surface is fixedly bonded to the gantry 1 in a standing posture. Has been. The accommodation opening 31 extends in the vertical direction so that its width is slightly larger than the outer diameter of the reinforcing bar f accommodated therein, and the opening edge 32 on the side close to the vibration table 2 of the accommodation opening 31 vibrates. The table 2 is substantially flush with the front side surface 24 which is inclined forwardly downward.

  In FIG. 1, the supply mechanism S is located above the accommodation mechanism H. The supply mechanism S includes a girder member 4 extending beyond the length of the accommodation mechanism H (FIG. 2), and the lower surface of the girder member 4 has a plurality of locations (this embodiment) at intervals equal to the installation interval of the accommodation mechanism H. Then, the holding body 5 (FIGS. 1 and 3) is fixed to three places. The holding body 5 is formed with a receiving opening 51 as a receiving portion at the center of the long plate and is formed into a substantially inverted U-shape as a whole, and a girder member via the bracket 41 in a standing posture with the receiving opening 51 opened downward. 4 is fixed to the lower surface. The holding body 5 is provided with gate means 6 at the opening of the receiving opening 51. The gate means 6 is provided with locking pieces 61A and 61B provided at the left and right vertical positions with the receiving opening 51 interposed therebetween.

  Each of the locking pieces 61A and 61B is formed in an L-shape and arranged symmetrically with each other, and is supported on the plate surface of the holding body 5 so as to be rotatable by the shaft body 62 at an intermediate bent portion positioned close to the receiving opening 51. ing. When the locking pieces 61A and 61B are turned to the advanced position shown in FIG. 1, the locking pieces 61A and 61B protrude into the receiving opening 51 at positions that are separated by the outer diameter of the reinforcing bar f up and down. A protrusion 63 is formed. A rod 641 of a driving cylinder 64 is connected to the base ends of the locking pieces 61A and 61B. The locking pieces 61A and 61B are locked by the driving cylinder 64 into the advance position and the receiving opening 51, respectively. A rotation operation is performed between the protrusion 63 and the retracted position (the chain line in FIG. 1) where the protrusion 63 is eliminated.

  As shown in FIG. 3, the girder member 4 of the supply mechanism S is movable in a three-dimensional space with two left and right portions of the upper surface suspended from the crane by wires 42. The holding body 5 provided on the girder member 4 is more central than the left and right holding bodies 5 so as to hold the reinforcing bar f in a curved state in accordance with the curvature of the mounting surface of the mesh reinforcing jig 6. The holding body 5 is positioned below. The same applies to the above-described accommodation piece 3 (FIG. 1), and the position of the accommodation piece 3 at the center in the longitudinal direction of the reinforcing bar is lowered below the position of the remaining two accommodation pieces 3 so that the rebar f is in the accommodated state. Is bent into a predetermined shape by its own weight.

  In the distribution device having such a structure, the reinforcing bars f for forming mesh bars are placed on the vibration table 2 of the gantry 1 (FIG. 2) and loaded on them. An example of the reinforcing bar f has a length of 10 m and an outer diameter of 50 mmφ. When the vibration motor 22 is operated in a state where the reinforcing bars f are loaded on the vibration table 2, the laminated state of the reinforcing bars f breaks down and is sequentially transferred forward (right side in FIG. 1) on the vibration table 2, and its front side surface. 24, it enters and falls into the accommodation opening 31 of the accommodation piece 3 through the opening edge 32 from above. Thereby, as shown in FIG. 1, the reinforcing bars f are accommodated in the accommodation opening 31 in a line in the vertical direction.

  In this state, the girder member 4 of the supply mechanism S is moved by the crane so as to match the position where the accommodation mechanisms H are connected in a plan view as shown in FIG. Next, it is located above each accommodation piece 3 of the accommodation mechanism H. In this state, the locking pieces 61A and 61B of each holding body 5 are rotated backward so that the locking projection 63 does not protrude into the receiving opening 51, and then the beam member 4, that is, each holding body 5 is lowered. Thus, the reinforcing bars f arranged in a line in the up-down direction in the receiving opening 31 are also relatively moved into the receiving opening 51.

  Subsequently, the locking pieces 61 </ b> A and 61 </ b> B of each holding body 5 are advanced and rotated so that the locking projections 63 protrude into the receiving openings 51. Thereby, dropping of the reinforcing bar f relatively entering the receiving opening 51 is restricted, and the reinforcing bars f are held in the receiving opening 51 in a state of being aligned in the vertical direction. Therefore, when the girder member 4 of the supply mechanism S is raised by the crane, the reinforcing bar f is transported upward outside the receiving opening 31 while being held in the receiving opening 51 (FIG. 1).

  Thereafter, the girder member 4 is moved above the mesh bar manufacturing jig 7 (FIG. 3), and the attitude of the girder member 4 is changed by 90 degrees in plan view depending on whether the reinforcing bars f are arranged in the vertical or horizontal direction. In this state, the holding members 5 are positioned directly above the triangular concave grooves 71 formed vertically and horizontally at equal intervals on the curved mounting surface of the jig 6, and the reinforcing bars are moved into the triangular concave grooves 71 one by one. f is supplied.

  Supply of the reinforcing bar f into the triangular groove 71 is performed in the following process. That is, first, the lower locking piece 61 </ b> A (FIG. 1) of the holding body 5 is rotated backward so that only the lowermost reinforcing bar f in the receiving opening 51 is placed in the triangular groove 71 below the receiving opening 51. Then, the lower locking piece 61A is advanced and rotated again. In this state, when the upper locking piece 61B is rotated backward, the reinforcing bar f in the receiving opening 51 comes into contact with the locking projection 63 of the lower locking piece 61A. Until it moves down by its own weight. Thereafter, the upper locking piece 61B is advanced and rotated again.

  Subsequently, the girder member 4 is moved in a horizontal plane in a predetermined amount in parallel, and each holding body 5 is positioned immediately above the next adjacent triangular concave groove 71 of the mesh streak manufacturing jig 7, and is moved down by the above procedure. The side and upper locking pieces 61A and 61B are sequentially rotated so that only the lowermost reinforcing bar f is detached and dropped from the receiving opening 51 to supply one reinforcing bar f into the triangular groove 71. Thereafter, this is repeated, and the reinforcing bars f are supplied in parallel to the mesh bar manufacturing jig 7 one by one at regular intervals. The reinforcing bars f supplied on the jig 7 are bound together by a method similar to the conventional method to form mesh bars.
