When the reinforcing bar mat 4 cut to a predetermined size is supplied to the press device 50, the pneumatic machine 53 operates to lower the upper die 51, and press the reinforcing bar mat 4 between the lower die 52 and the lower die 52. All the horizontal streaks 3 are simultaneously bent into a corrugated shape and molded into a corrugated reinforcing bar mat 1. At this time, as shown on the right side of FIG. 4, since the respective mold members 54a and 54b of the upper mold 51 and the lower mold 52 are connected to each other by the link 55, the convex mold member 54
When the concave mold member 54b is pushed in by a, the width between the mold members 54a and 54b is slightly reduced, and no excessive stress is applied to the reinforcing bar mat 4. In addition, the lifter 5
6 is pressed down at the time of pressing, but rises when the pressing is completed, and the processed corrugated reinforcing mat is lowered into the lower mold 5.
The lower mold 52 does not hinder the conveyance of the corrugated reinforced mat because the lower mold 52 is raised above the upper surface of the second mold 2.

The pressing device 50 includes an upper die 5 and a lower die 5.
The rebar mat 4 cut by the cutting device 40 is inserted into the press device 50 in conjunction with the vertical movement of the first and second 52, and the corrugated rebar mat 1 processed into a corrugated shape by the press device 50 is transferred to a transport device described later.

a is between the cutting device 40 and the pressing device 50, and similarly, the cylinder 64b is between the pressing device 50 and the unloading device 70,
Each is designed to reciprocate. Therefore, when the gantry 62 is moved to the left in FIG. 1 immediately before the reinforced mat 4 is cut by the cutting device 40, the cylinder 64a is located near the right end of the cutting device 40, and the cylinder 64b is located near the right end of the press device 50. Located in.

When the cutting device 40 and the press device 50 are operated to complete the cutting or press working of the reinforced mat 4 already supplied, the cylinders 64a and 64b are operated to lower the locking claw 63, and The right ends of the processed reinforcing bar mat 4 and the corrugated reinforcing bar mat 1 are hooked from above. When the gantry 62 is moved to the right in FIG. 1 in this state, the reinforced mat 4 just cut is
It is supplied to the press device 50 by sliding upwards, and the pressed corrugated reinforcing bar mat 1 is similarly supplied to the unloading device 70.

As the unloading device 70, conventionally known various unloading devices can be used. For example, an unloading cart 72 moving on a rail 72 may be used.

At this time, the corrugations of the corrugated reinforcing bar mat 1 fit into the ridges on the upper surface of the carry-out carriage 72. Therefore, even if the corrugated reinforcing bar mat 1 is subsequently laminated thereon, it is possible to prevent the corrugated reinforcing bar mat 1 from being displaced or deformed. As the corrugated reinforced mats 1 are sequentially laminated in this way, the table lifter is lowered. When the desired number of sheets is reached, the table lifter is slightly moved by the cylinder and laminated stepwise.
When the desired number is reached again, the position of the table lifter is returned to the original position, and the layers are successively stacked at different levels. Carriage 7
When 2 is full, it can be carried out to the next process as it is.

The above-described apparatus for manufacturing a corrugated rebar mat according to the present invention can be controlled and automated by a controller.

In addition, the main bar supply device is configured such that a plurality of main bars are supplied one at a time at a desired pitch by storing main bars of a predetermined length which are irregularly conveyed one by one in a groove provided on the outer periphery of the cylindrical rotary drum. Since the main bars supplied from the cutting machine can be aligned at a high speed and supplied to the welding device, the production speed can be further improved.

If the cutting device is arranged so as to be position-adjustable in the traveling direction of the wire for the horizontal bar, the size of the horizontal bar protruding from the main bar in the width direction of the reinforcing bar mat and the guide window for cutting a part of the main bar are provided. The position can be easily changed. In addition, if the press device is provided with a moving device that supplies the rebar mat cut in the previous process to the press device and transports the pressed corrugated rebar mat to the next process, the press device can be used together with the processing of the press device. This is advantageous because the reinforced mat can be automatically transferred.
