It goes without saying that 9 may be constructed of a limit switch or other proximity sensor such as grass, instead of the above-mentioned example in which the disc rotates in contact with the flat surface of the workpiece.

Next, the operation of this form panel manufacturing apparatus will be explained.

(1) From the starting end side of the first transfer path 10, the rafter A is first supplied, and the flat material B is secondly supplied. As shown in Fig. 12, the gate for forming the formwork panel P1 having nine rafters A on both sides is equipped with three guide rails 12.12°12 for transporting one tree as shown in Fig. 4. Of these, two guide rails 12.12 at the left end and the middle position are used, and when manufacturing formwork panel P2 having three rafters A, A, A as shown in Fig. 13, three guide rails are used. guide rail 12, 12.1
2 is used. Each guide rail 12.12 at the shiftable intermediate position and at the right end is adjusted to a position corresponding to the width dimension of the formwork panel to be manufactured. These adjustments are made by driving two motors (not shown) to adjust each position adjustment shaft 16.
This is done by rotating 17.

(2) The rafter A placed on the guide rail 12 is
Vertical piece 1 of drive roller 14 and guide rail 12 shown in the figure
The drive roller 14, which is sandwiched between free rollers 5 to 18 and driven once, sends it to the terminal end of the transfer path IO. On the other hand, the flat material B is placed on a free roller 21 that slightly protrudes from the vertical piece 15 of each guide rail 12, and the -
Since the side ends are brought into contact with the guide plate 20, the paper is sent out along the guide plate 20 while regulating its position in the width direction.

(3) The flat material cutting mechanism 23 located in the middle of the transfer path 10 has its circular saw 22 adjusted in advance to a predetermined position in the width direction according to the width dimension of the formwork panel to be manufactured. If the width of the planar material B is larger than the desired width, it is cut into a fixed width using the circular saw 22.

(4) If the length of the flat material B is less than the length of the formwork panel to be manufactured and it is to be covered by two flat materials, for example, two sheets of flat material are placed one behind the other on the transfer path 10. Planar materials are supplied, and these two planar materials are transported with their front and rear ends abutting each other by a presser roller mechanism 31 in the middle of the transport path.

(5) At the end of the first transfer path 10, the stopper 2
The positions of each section of 6 are adjusted in advance so as to be aligned with each of the corresponding guide rails 12,
The stop arm 28 is set in a hanging position as shown by the solid line in FIG. The rafters A and the flat material B that have been transferred through the above-described process have their tips aligned with the stop arm 2.
The rafter A and the planar member B
are stopped with their tips aligned and the planar material B overlapping the rafter A. A detection means including a limit switch (not shown) detects the contact of the rafter A and the flat material B with the stop arm 28, and thereby the downward nailers 34 and 34 corresponding to the rafters A and A on both sides are activated. By driving, these rafters A, A and the planar member B are connected by nailing from above.

Like the stopper 26, each downward nail gun 34 is adjusted in position in advance so as to be aligned with each guide rail 12. If three rafters A, A, A are sent,
At the time of nailing, the downward nail gun 34 corresponding to the middle rafter A does not operate. Thereafter, the stopper 26 is driven, and the stop arm 28 of each section is rotated and stopped in a horizontal position as shown by the imaginary line in FIG.

(6) Next, the crosspiece supply mechanism 39 operates.

Also in this crosspiece supply mechanism 39, the distance between the left and right mechanism parts is adjusted in advance according to the length of the crosspiece C to be supplied.

The crosspiece pushing arm 45 and the crosspiece holding arm 47 of the left and right mechanical parts are on standby in the posture shown by solid lines in FIG. The front end of the guide plate 40 abuts against the rear end of the guide plate 40, and the guide rail 41a is positioned slightly below the back surface of the front end of the workpiece above which the guide rail 41a stops. As shown in FIG. 10(b), the crosspiece C, whose both ends are mounted on the left and right guide rails 40a and supported by the crosspiece pushing arm 45, is moved counterclockwise in FIG. 10(b) by the backward drive of the cylinder 46. The guide rail 4 is pushed by the crosspiece pushing arm 45 that rotates in the direction
0a and 41a, it is pushed up to the upper position shown in Figure (C). The guide rail 41a is arranged so that when the guide plate 41 is in the position shown in FIG. 10(b), the crosspiece C located on the rail is positioned slightly below the flat material B waiting above it with a predetermined distance. is set, and even if flat material B is warped downward,
In the above-mentioned pushing-up operation, there is no problem that the crosspiece C hits the tip of the flat material B and the operation is hindered. When the middle rafter A is waiting on the transfer path lo, 2. Due to the upward movement of the pier C, the middle rafter A is pushed backwards by the width dimension of the pier C, but the posture of the pier C is not disturbed by this movement. ,
Prior to this, the cylinder 48 is driven backward, and the crosspiece holding arm 47 rotates clockwise as shown in FIG.
By this, the crosspiece C is lightly held.

When there is no risk of such disturbance of the crosspiece C, the crosspiece holding arm 47 is moved while the crosspiece C is being pushed up, as shown in FIG.
It is also possible to maintain the crosspiece C in a position where it is not pinched, as shown in FIG. After this, the cylinder 42 is driven forward, and the fifth first
As shown by the imaginary line in FIG. 0(e), the guide plate 41 rotates a little clockwise as shown by the arrow symbol, and the crosspiece C on the guide rail 41a is pushed between the rafters A on both sides of the front end of the workpiece.

(7) After the above-mentioned crosspiece holding state, the horizontal nailers 49 and 49 arranged on both sides of the end of the transfer path 10 are driven, and the crosspiece C and both surveying rafters A, A are moved horizontally. Joined by nailing from the direction. After this, the crosspiece supply mechanism 39 returns to its original position.

(8) Next, the presser roller mechanism 31 (first illustration) and drive roller 14 (fourth illustration) are restarted, and the workpiece W on the transfer path 10 is advanced by a predetermined amount and 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 the workpiece W has been moved by a certain distance, the downward nailer 34 is driven, and the flat material B and the rafter A are intermittently connected by nailing at predetermined intervals. If there is an intermediate rafter A, the corresponding downward nailer 34 is also driven at this time, and the intermediate rafter A and the flat material B are also connected by nailing. Thereafter, similar operations are repeated at predetermined notches, 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. It is only necessary to operate the horizontal nail gun 49 each time.

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 recess, ~
When the workpiece W advances into the third transfer path 63 until the frame material frame D3 is aligned with the small rafter or small crosspiece on the seat 69, 70, the third fixed position 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.
The frame material frame having a diameter of 0a is kept in standby above the seat 70, and this receiver is sequentially moved by a predetermined pinch in the direction of the transfer path width along the small crosspiece on the seat 70 as shown by the arrow mark in FIG. While moving forward, 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 the downward nailing machine 82 advances to the terminal position of , the small crosspiece and the flat part of the workpiece are joined together 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.

〔Effect of the invention〕

The present invention has the above-mentioned configuration, and the rafters transferred by the rafter transfer path and the planar material transferred by the planar material transfer path are stopped by the stopper so that their tips are aligned at the end of the transfer path, and this In this state, the rafters and the planar material were connected by nailing from above the planar material using the first nailing means, and the crosspieces were fitted between the rafters on both sides by the crosspiece supply means, and were further placed on both sides of the end of the transfer path. Since the rafters and crosspieces on both sides are nailed together using the second nailing means, each process can be performed automatically and in succession, as shown in Figures 12 to 14. Formwork panels P1 to P3 having a framework structure, which are commonly used frequently, can be efficiently mass-produced without requiring two workers, and manufacturing costs can be significantly reduced.

In addition, the cutting mechanism installed in the middle of the plane material transfer path allows
Since the flat material being transported can be cut to a fixed width according to the parallel width of the rafters, there is no need for a pre-process such as cutting the flat material to a fixed width before supplying it, making it easier to formwork panels. It can be manufactured efficiently.
