The position detecting means 74 detects a stop position based on data from the traveling distance detector 18 which detects the traveling distance of the traveling stand 10.

First, the step processing control means 76 stops and positions the traveling stand 10 so that the tip of the nailing machine 20 is located at a position 15 mm before the intermediate position Q, for example, and performs nailing to perform the intermediate position Q. The nailing of the end of the plate material 2 in front is performed, and then the nailing is performed next to the intermediate position Q.

Next, the operation of the nailing device for a panel according to this embodiment will be described with reference to the flow charts shown in FIGS. 10 to 12 for the case of the straight panel P and the case of the stepped panel P. . First, a case where a straight panel P as shown in FIG. 13 is formed will be described. As shown in FIG. 9, necessary information is input to the input means 61 in advance (1-1 in FIG. 10). For example, the width dimension of the panel P is such that the left dimension L _L = 400 mm and the right dimension L _R =
It consists of 400 mm. Also, for example, the basic pitch P _O =
300 mm, and inputs the seam pitch P _t = 30 mm between the nail 3 across the seam of the plate 2. Thereby, the nailing machine 20
, The basic pitch distance, the fixed distance, and the joint pitch distance are determined.

Next, the ready button 62 is pressed (FIG. 10).
As shown in FIGS. 6A and 6B, the clamp mechanism driving unit control means 70 activates the clamp mechanism driving unit 45, and firstly, the divided second clamp mechanisms 40A and 40B are separated by an outer pressing member 42. It is moved so as to have a width f (for example, f = 10 mm) more than the width specified by the input means 61 (1-3). On the other hand, by pushing the preparation button 62, the nailing machine 20 is moved to a position corresponding to the width dimension of the panel P specified by input to the input means 61 (1-
3). In this state, the bar 1 is placed on the table 6 along the outer holding member 42, and the plate members 2 are lined up on the bar 1 (1-4). In this case, if the pressing is performed against the stopper 9 at one end of the table 6, the gap between the joints is reduced. In this case, the divided second clamp mechanism 40
Since the outer pressing members 42 of A and 40B are wider than the predetermined width, there is a margin, and the mounting of the crosspiece 1 and the plate material 2 is easily performed.

Next, as shown in FIG. 1, FIG. 2 and FIG. 13, a plurality of pieces 50 are placed on the piece support rails 51 and positioned at the joint position and also at the first nailing point. . Further, two nails are arranged side by side at the final nailing point (1-5). In this state, when the start button 63 is pressed (1-6), the clamp mechanism driving unit control means 70
Operates the clamp mechanism driving unit 45 to first move each of the divided second clamp mechanisms 40A and 40B so that the interval between the outer pressing members 42 becomes the width designated by the input means 61 (1-7). Thereafter, the first and second clamp mechanisms 30,
At 40, the air cylinder devices 34, 44 are operated to move the inner pressing members 33, 43 to the outer pressing members 32, 4.
2 and the barge 1 is clamped (1-8).

Then, as shown in FIG. 11, the traveling stand 10 starts traveling (2-1, 2-2). When the piece detector 52 detects the first piece 50 during traveling (2-3),
After the detection, the first control means 64 sends a travel stop signal after traveling a specified distance and sends a nailing operation signal to perform nailing (2-4). Thereby, nailing of one end side of the panel P is performed. Thereafter, a traveling start signal is transmitted, and the traveling stand 10 travels (2-
5). In this traveling, the width change judging means 72 judges whether or not the width of the plate material 2 is changed. Since the width of the panel P input to the input means 61 is right or left because the panel P is a straight panel now, Since there is no difference, it is determined that there is no width change (2-6N).

In this traveling process, the frame detector 52 detects the frame 50 (2-7), and when there is no detection (2-7N), the basic pitch distance travel determining means 67 determines the basic pitch distance. It is determined whether the vehicle has run (2-10),
If not, the vehicle continues traveling (2-10N, 2-5, 2
-6). When the frame detector 52 detects (2-7)
Y), it is determined that the position is the seam position, and the control means 6
5 is operated and the vehicle is driven for a certain distance.
If no is detected (2-8N), a running stop signal is sent out after running for a certain distance, and a nailing operation signal is sent out to perform nailing. After that, a driving start signal is sent out,
After running the joint pitch distance set as the distance between the nails 3 sandwiching the seam of the plate material 2, a running stop signal is transmitted and a nail driving operation signal is transmitted to perform nail driving. This allows
Nailing before and after the seam is performed. Thereafter, a traveling start signal is transmitted to continue traveling (2-5).

On the other hand, during this traveling process, the frame detector 5
If the basic pitch distance travel determining means 67 determines that the vehicle has traveled the basic pitch distance (2-10Y) when the second piece 2 does not detect the piece 50 (2-7N), the intermediate control means 6
8 functions to send a driving stop signal and a nailing operation signal to perform nailing (2-11N, 2).
-12). Thereby, nailing is performed for each basic pitch P _O. In this case, the basic pitch distance travel determining means 67
Is determined to have traveled the basic pitch distance, and then travels a check distance until a travel stop signal is sent. If the frame detector 52 detects the frame 50 during the travel (2-11Y), the intermediate control stopping means The function of the intermediate control means 68 is stopped by 69, and the detected piece 50 indicates a joint,
Perform nailing before and after the seam (2-9). Therefore, there is no situation where the nail 3 is driven into the vicinity of the joint by a piece, and waste is prevented. In this way, as shown in FIG. 13, the nail 3 is hit at every basic pitch P _O , and when the seam is reached, the traveling stand 10 is run while hitting the nail 3 before and after the seam.

When the piece detector 52 detects the piece 50 during the predetermined distance traveling period after the piece detector 52 detects the piece 50 (2-8Y), the pieces 50 are continuously detected. Therefore, the end point is determined, and after traveling a certain distance, a travel stop signal is sent and a nailing operation signal is sent out to perform nailing (2-13), and the nailing is ended as shown in FIG. Things. When the nailing is completed, the traveling stand 10 moves backward and returns to the original position, and the inner pressing member 43 is retracted from the outer pressing member 42 by the air cylinder device 44 of the clamp mechanism, and the clamp is released. The outer pressing members 42 of the divided second clamp mechanisms 40A and 40B are separated. Then, the stopper 9 is released, and the panel P is conveyed to one end side of the table 6 and discharged by the rolling of the roller 8 of the table 6. For example, when the length of the panel P is longer than the table 6 (for example, when manufacturing a 6 m or 8 m panel), the end of nailing is discharged to one end of the table 6. At the end of the nailing, the pier 1 and the plate 2 are continuously placed on the table 6 and nailing may be performed in the same manner as described above. Thereby, a long panel P can be formed.

Next, a stepped panel P as shown in FIG.
Will be described. In advance, as shown in FIG.
The necessary information is input to the input means 61 (1- in FIG. 10).
1). For example, the width dimension of the panel P is the left dimension L _L = 3
00 mm, right side dimension L _R = 400 mm. Further, for example, type seam pitch P _t = 30 mm between the base pitches P _O = 300 mm, nails 3 across the seam of the plate 2. Thereby, the distance of the nailing machine 20 in the width direction, the basic pitch distance, the fixed distance, and the seam pitch distance are determined.

Next, the ready button 62 is pressed (FIG. 10).
As shown in FIG. 6, the clamp mechanism driving unit control means 70 activates the driving mechanism of the clamping mechanism 40, and first, the divided second clamping mechanisms 40 </ b> A and 40 </ b> B are separated by the gap between the outer pressing members 42. It is moved so as to have a width f (for example, f = 10 mm) more than the width specified by the input means 61 (1-3). In this case, the left outer holding member 42 and the right outer member are stepped from each other. On the other hand, by pushing the preparation button 62, the nailing machine 20 is moved to a position corresponding to the width dimension of the right panel P input and specified by the input means 61 (1-3). In this state, FIG.
As shown in FIG. 4, the pier 1 is placed on the table 6 along the outer retainer 42 by allocating around the intermediate position Q formed at the end of the outer retainer 42, and the plate 2 is Arrange them on the top (1-4). At this time,
As shown in FIG. 14, the cross bar 1 on the side of the split clamp mechanisms 40A and 40B for the narrow plate 2 is mounted below the wide plate 2 so as to extend a predetermined dimension (for example, about 200 mm). Set aside. In this case, since the outer pressing members 42 of the divided second clamp mechanisms 40A and 40B are wider than a predetermined width, there is a margin, and the crosspiece 1 and the plate material 2 are provided.
Is easily mounted.

Next, as shown in FIG. 14, a plurality of pieces 50 are placed on the piece support rail 51, and are positioned at the joint position and also at the first nailing point. Further, two nails are arranged side by side at the final nailing point (1-5).
Since the intermediate position Q is separately detected, the piece 50 is not placed. Further, even if the frame is placed, the detection of the frame 50 at the intermediate position Q may be invalidated. In this state, when the start button 63 is pressed (1-6), the clamp mechanism driving section control means 70 causes the clamp mechanism driving section 45 to operate.
, First, each of the divided clamp mechanisms 40A, 40B
Is moved so that the interval between the outer pressing members 42 becomes the width designated by the input means 61 (1-7). Thereafter, in the first and second clamp mechanisms 30 and 40, the air cylinder devices 34 and 44 are operated and the inner pressing members 33 and 43 are operated.
Is advanced with respect to the outer pressing members 32 and 42 to clamp the crosspiece 1 (1-8).

Then, as shown in FIG. 11, the traveling stand 10 starts traveling (2-1, 2-2). When the piece detector 52 detects the first piece 50 during traveling (2-3),
After the detection, the first control means 64 sends a travel stop signal after traveling a specified distance and sends a nailing operation signal to perform nailing (2-4). Thereby, nailing of one end side of the panel P is performed. Thereafter, a traveling start signal is transmitted, and the traveling stand 10 travels (2-
5). In this traveling, the width change determining means 72 has determined whether or not the width of the plate 2 has been changed. Since the width of the panel P input to the input means 61 is right or left because the panel P is now a stepped panel. , It is determined that the width has changed (2
-6Y).

In this traveling process, the position determining means 75
In (3), it is determined whether or not the position detected by the position detecting means 74 is the position stored in the position storing means 73.
-1), when it is determined to be no (3-1N), the frame detector 5
2 detects the piece 50 (2-7), and when there is no detection (2-7N), the basic pitch distance travel determination means 6
7 has traveled the basic pitch distance (2-1).
0), if not, continue running (2-10N, 2-
5, 2-6). When the frame detector 52 detects (2
-7Y), it is determined that the position is the seam position, and the control means 65 functions two or more times to run the vehicle for a certain distance. If no detection is made by the frame detector 52 during this time (2-8N), the vehicle runs after the certain distance. A nailing operation signal is sent together with a stop signal and nailing is performed. Thereafter, a traveling start signal is transmitted, and after traveling a joint pitch distance set as a distance between the nails 3 sandwiching the joint of the plate material 2, a traveling stop signal is transmitted, and a nailing operation signal is transmitted to perform nailing. . Thereby, nailing before and after the seam is performed. Thereafter, a traveling start signal is transmitted to continue traveling (2-5).

On the other hand, during this traveling process, the frame detector 5
If the basic pitch distance travel determining means 67 determines that the vehicle has traveled the basic pitch distance (2-10Y) when the second piece 2 does not detect the piece 50 (2-7N), the intermediate control means 6
8 functions to send a driving stop signal and a nailing operation signal to perform nailing (2-11N, 2).
-12). Thereby, nailing is performed for each basic pitch P _O. In this case, the basic pitch distance travel determining means 67
Is determined to have traveled the basic pitch distance, and then travels a check distance until a travel stop signal is sent. If the frame detector 52 detects the frame 50 during the travel (2-11Y), the intermediate control stopping means The function of the intermediate control means 68 is stopped by 69, and the detected piece 50 indicates a joint,
Perform nailing before and after the seam (2-9). Therefore, there is no situation where the nail 3 is driven into the vicinity of the joint by a piece, and waste is prevented. In this way, as shown in FIG. 14, the nail 3 is hit at every basic pitch P _O , and when the seam comes, the traveling stand 10 is run while hitting the nail 3 before and after the seam.

As shown in FIG. 12, when the position judging means 75 judges that the position detected by the position detecting means 74 is the position stored in the position storing means 73 in the traveling process (3-1Y). That is, when the intermediate position Q is detected, the step processing control means 76 performs nailing processing at the step where the width of the plate material 2 changes in the middle. First, the traveling stand 10 is stopped and positioned so that the tip of the nailing machine 20 is located at a position in front of the intermediate position Q, and nailing is performed to nail the end of the plate 2 before the intermediate position Q. (3-2). Next, after the intermediate position Q, it is determined whether the wide plate 2 or the narrow plate 2 is to be nailed after the input means 61.
(3-3), and when it is determined that the width is wide (3-3Y), the traveling stand 10 is driven in order to stop at two places and the nailing machine 20 performs nailing. (3-4) After that, the vehicle is driven in the reverse direction (3--3).
5), the function of the nailing mechanism control means 71 is executed to move the nailing machine 20 to the wide position (3-6), and finally, the tip of the nailing machine 20 is located beyond the intermediate position Q. The driving stand 10 is stopped and positioned so as to perform nailing (3-7). Thereby, as shown in FIG. 14, the extending portion 1a of the crosspiece 1 on the side of the divided clamp mechanisms 40A, 40B for the narrow plate 2 is nailed at the lower side of the wide plate 2. Therefore, the step portion is less likely to bend and the strength is improved.

On the other hand, the above-mentioned wide plate 2 or narrow plate 2
If it is determined that the width is narrow (3-3N), the function of the nailing mechanism control means 71 is executed to move the nailing machine 20 to the narrow position (3-8). 10 is driven in reverse to stop at two places and the nailing machine 2
0 (3-9), and then move forward (3-10) to move the nailing machine 2 from the intermediate position Q to a position ahead.
The driving stand 10 is stopped and positioned so that the leading end of the zero is positioned, and nailing is performed (3-7). This also
Split clamp mechanism 40A, 40B for narrow plate 2
Since the extending portion 1a (FIG. 14) of the side pier 1 is located below the wide plate member 2 and nailed, the step portion is less likely to bend and the strength is improved.

When the nailing processing by the step processing control means 76 is completed, the nails 3 are driven at every basic pitch P _O in the same manner as described above. Run the traveling stand 10 while hitting (2-
5-12). In this process, the piece detector 52 sets the piece 50
During a certain distance traveling period after detecting the
When the piece 50 is detected (2-8Y), since the piece 50 is continuously detected, it is determined to be the end point, and after traveling a certain distance, a traveling stop signal is transmitted and a nail driving operation signal is transmitted. Then, nailing is performed (2-13), and the nailing is terminated as shown in FIG. When the nailing is completed, the traveling stand 10 moves backward and returns to the original position, and the inner pressing member 43 is retracted from the outer pressing member 42 by the air cylinder device 44 of the clamp mechanism, and the clamp is released. , Divided second clamp mechanism 4
The outer pressing members 42 of 0A and 40B are separated. Then, the stopper 9 is released, and the panel P is conveyed to one end side of the table 6 and discharged by the rolling of the roller 8 of the table 6.

When the distance from the outer surface of the plate member 2 on the second clamp mechanism 40 side to the outer surface of the crosspiece 1 is input to the input means 61, the nailing machine driving unit control means 7
1 moves the nailing machine 20 to a required position so that the nail 3 is driven into the crosspiece 1 inside the outer surface of the plate material 2. In this case, since the outer holding member 42 of the clamp mechanism has a height enough to hold the plate member 2, it cannot be moved to the lower part of the plate member 2, so that an elongated spacer is provided between the outer holding member 42 and the pier 1. What is necessary is just to cope by interposing. As a result, as shown in FIG. 15, when the panels P are joined at a right angle, the resulting panel P can be hidden so as not to expose the end face or the crosspiece surface of the plate material 2 of another panel P.

As described above, according to the panel nailing apparatus of the present invention, a plurality of pieces are arranged on a piece support rail to indicate a predetermined position such as a joint of a plate material, and the pieces are detected. The driving stand is run while detecting with a tool, and the nailing is performed on the nailing machine, so that the interval between the nails of the nailing machine can be appropriately changed. Even if it is mixed, it is possible to securely fix the plate material, especially the nail driving before and after the seam of the plate material can be ensured, forming a strong panel that is hard to peel off the plate material You can do it. For this reason, it was possible to easily cope with the reuse of the plate material, and to provide a very useful panel nailing device.

Further, since the control section is provided with the first control means, the second and subsequent control means, and the final control means, the nailing at both ends of the panel and the middle seam can be reliably performed. In addition, it is possible to reliably form a strong panel that is hard to peel off the plate material. Furthermore, if the basic pitch distance travel determining means is provided with an intermediate control means for performing nailing when it is determined that the vehicle has traveled the basic pitch distance, a nail is driven before and after the seam when the seam is reached.
Since nails can be driven at each basic pitch, even if the length of the board in the longitudinal direction is long, it can be securely fastened with nails, and a strongly strong panel that is hard to peel off the plate material can be formed. You can do so.

Further, the vehicle travels for a check distance until the basic pitch distance travel determining means determines that the vehicle has traveled a predetermined distance and then sends a travel stop signal. When the frame detector detects a frame during the travel, the intermediate distance is determined. In the case where the intermediate control stop means for stopping the function of the control means is provided, there is no possibility that a nail is driven into the vicinity of the seam by one piece, and waste can be prevented, and the manufacturing speed can be increased accordingly. it can.

Further, a width change determining means for determining whether or not the width of the plate material has been changed, and a step for performing nailing processing in the step portion having the width change when the width change determining means determines that the width has been changed. In the case where the section processing control means is provided, even in the stepped panel, the fastening of the plate material can be reliably performed.
The nail can be reliably driven before and after the seam of the plate material, and it is possible to form a strong panel that is hard to peel off the plate material.
