The workpiece W on the transfer path 10 moves forward by a predetermined amount and is stopped again. This workpiece sizing feeding control is performed based on a detection signal from a first sizing device 52 that is in contact with the flat surface of the workpiece and rotates as the workpiece moves. After moving the workpiece W by a fixed distance,
The downward nailer 34 is driven, and the planar material B and the rafter A are intermittently nailed together at predetermined intervals. middle rafter A
If there is one, the corresponding downward nailer 34 is also driven at this time, and the intermediate rafter A and the flat member B are also connected by nailing. Thereafter, the same operation is repeated with a predetermined pinch, and nailing is performed from above to the rear end of the workpiece. When manufacturing a formwork panel P3 incorporating a plurality of crosspieces C as shown in FIG. 14, in the above steps,
Each time the workpiece W is fed by a fixed length, the crosspiece supply mechanism 39 is repeatedly driven, and the horizontal nailer 49 is also operated each time.

(9) At the end of the above steps, the front end of the work W has advanced to the starting end of the second transfer path 35, and is transferred to the terminal end side by the pair of drive rollers 53 of the transfer path 35. When the workpiece W is transferred by a predetermined amount on the second transfer path 35, the amount of movement is detected by the second sizing device 64 that rotates in contact with the flat surface of the workpiece. The vertical cutting mechanism 55 is activated, and the circular saw 54 cuts the flat material B in the rear half of the work in the vertical direction.

As shown in Fig. 15, there is a notch in the center of the rear end.

In order to obtain a formwork panel P4 having the above-mentioned longitudinal cutting mechanism 55, the two circular saws 54, 54 of the longitudinal cutting mechanism 55 are operated simultaneously. The positions of these circular saws 54, 54 in the transfer path width direction are adjusted in advance in accordance with the width dimension of the recessed notch DI. On the other hand, as shown in FIG. 16 and FIG.
When obtaining P6, only one circular saw 54 will be activated.

Similarly, when the workpiece W has been transferred by a predetermined amount based on the detection signal of the sizing device 64, the transfer of the workpiece W is temporarily stopped and the transverse cutting mechanism 60 is activated. Then, the circular saw 59 descends onto the flat surface of the workpiece and cuts the recessed portion DI.
- A portion corresponding to the horizontal side of D3 is cut in the width direction.

When the workpiece W is further transferred by a predetermined amount, the sizing device 6
The work W is stopped again based on the detection signal No. 4, and the transverse cutting mechanism 60 is activated to cut the rear end of the work W in the width direction, and the work W is finally cut into the formwork to be obtained. Processed to the specified length of the panel.

(10) The workpiece W cut in the second transfer path 35 is further transferred to the third transfer path 63.

The T-shaped grooves 69a to cross grooves 70a of each frame material receiving seat 69.70 arranged on the table 67 of this transfer path 63 have
Small rafters or crosspieces that will become the frame materials for the recessed parts D1 to D3 of the formwork panels P and P6 shown in FIGS. 15 to 17 are placed in advance as shown by imaginary lines in FIG. At the same time, the arrangement of each frame material receiving seat 69°70 is a 2-position adjustment axis. 1,72.
By appropriately rotating 73, the above-mentioned concave notches D1 to D
.

pre-adjusted to the dimensions of In addition, the elevating mechanism 66
As shown by solid lines in FIG. 7, the swing cams 75, 75 are in the horizontal position, the table 67 is mounted on the support 94, and at this time, each frame material receiver is placed on the seat 69, 70. The ends of the upper small-sized rafters or small-sized crosspieces are lowered to a height where the transfer of the workpiece W is not obstructed. Workpiece recessed part D1~
When the workpiece W advances into the third transfer path 63 until the frame material receiver D3 is aligned with the small rafter or small crosspiece on the seat 69, 70, the third constant that rotates in contact with the flat surface of the workpiece The size device 89 detects this, and the transfer of the workpiece W is temporarily stopped based on the detection signal.

Next, the cylinder 77 of the elevating mechanism 66 is driven backward, and its swing cam 75.75 rotates upward as shown by the imaginary line in FIG. 7, so that the table 67 is lifted upward.

As a result, the work W on the small-sized rafters or small-sized crosspieces approaches the lower end of the downward nail gun 82, 82 waiting above.

(11) The downward nailing machine 82 has a cross groove 7 in advance.
A frame material receiver having a diameter of 0a is placed on standby above the seat 70, and this receiver is moved along the small crosspiece on the seat 70 by a predetermined pinch in the width direction of the transfer path as shown by the arrow mark in Figure 1. While moving sequentially, the small-sized crosspieces and the flat part of the workpiece are connected by nailing at a plurality of locations. Next, the downward nail gun 82 sequentially steps forward along the small rafter by a predetermined pitch in the longitudinal direction of the transfer path as indicated by arrow marks in FIG. 11, each time.

Connect the small rafters and the flat part of the workpiece by nailing. Work W
When you step to the terminal position, the first downward nailing Ja82
In this case, the frame material receiver having the T-shaped groove 69a is moved along the small crosspiece on the seat 69 in the width direction of the transfer path, and each time the small crosspiece and the flat surface of the workpiece are connected by nailing.

(12) When nail driving by the downward nail gun 82 is completed, the elevating mechanism 66 is driven and the table 67 returns to its original lowered position. Also, along with this.

The downward nail gun 82 returns to its initial position.

(13) When the above steps are completed, the discharge mechanism 91 at the end of the transfer path 63 is driven, and the workpiece W is discharged to the outside of the machine.

jlJ [Effects of the Invention] The present invention has the above-described configuration, and by lifting the frame material setting table using the elevating means, frame materials such as small rafters and small crosspieces placed on this table can be moved into semi-finished products. The form panel semi-finished product placed on the set stand and waiting upwards is pressed against the area around the concave notch on the back side of the semi-finished product, and under certain conditions, the above-mentioned frame material is pushed into the concave notch from the front side of the semi-finished product. Because it is a nailing joint, it is easy to align the frame material to the recessed part of the semi-finished product, and the nailing is performed with the semi-finished product and the frame material completely in contact with each other. It is possible to obtain accurate and sufficient bonding strength, and it is possible to efficiently manufacture a formwork panel having a special framework structure having a recessed notch.
