Further, the four stacks 41a of the upper receiving member 40 are advanced, the stack 41b of the lower receiving member 40 is retracted, and the guide bar 47 is raised.
[0024]
In this state, the corrugated rebar mat 1 which has been slid and extruded one by one on the horizontal machine base 5 one by one by the mat transfer device in the previous process shown in FIG. The bar 6 is once transferred to the upper stage 41a of each stack 41a, which is almost at the same level as the machine base 5. Next, when the guide rod 47 descends and penetrates the mesh of the corrugated reinforcing bar mat 1 and the cylinders 44a shrink and the stacks 41a retreat at the same time, the corrugated reinforcing bar mat 1 moves on the carriage 10 along the guide rod 47. Then, as shown in FIG. 4, the wave-shaped depression is fitted on the protruding shape 12 of the carriage 10 and placed. Thereafter, the upper stacks 41a move forward again, and the guide rods 47 rise to return to the initial state. Then, the next corrugated reinforced mat 1 is carried in again, and is similarly sequentially stacked one by one on the cart 10.
[0025]
When the desired number of corrugated rebar mats 1 are loaded, the lower stack 41b advances to allow the corrugated rebar mats 1 to be stored, and the cylinders 23 and 53 are actuated to move the table 20 slightly in the longitudinal direction and at the same time Lower by height. Then, the corrugated rebar mat 1 stacked and stored on the stack 41b is similarly dropped on the carriage 10, and then the loading is continued again as described above. As described above, the carriage 10 is reciprocated and lowered every time the desired number of sheets are stacked, so that the corrugated reinforced mats 1 can be stacked in a different level.
[0026]
When a predetermined number of corrugated reinforcing bars 1 are loaded on the cart 10, the lifter 50 lowers the table 20 to the lowest position, releases the fixation of the cart 10, and advances the lower stack 41b. Further, the cylinder of the bogie moving device on the front side (the right side in FIG. 1) is operated to advance the box, the lever 32 is rotated to fit into the locking hole 15 of the bogie 10, and then the cylinder is operated in reverse.
