In addition, as a description of the process, first, description will be made on the manufacture of the pan-turn frame without using the vertical bars 2a as shown in FIGS.

First, a vertical frame member 1a, a horizontal frame member 1b, and rod members 2a and 2b corresponding to the standard of a desired wood panel P are prepared, and a card (for example, a punch card) corresponding to this standard is used as a control device. Put in. Then, in response to the information input to the card, the control device drives the motor 19b and rotates the worm screw 19 to laterally move the transport path 22a in the direction orthogonal to the transport direction. Then, as a result, the transport means B corresponds to the width of the pattern of the framework 2 desired by the transport paths 22a and 22b.

Next, when the movement of the transport path 22a is completed,
In the transporting means B, the motor 21 is driven in response to a signal from the control device, so that the portion of the transport chain 14 to which a large number of support blocks 12 and 13 are attached corresponding to the framework 2 to be manufactured is subjected to the framework work. To be in position.

In the automatically prepared state as described above, the operator fits one lower part of the prepared vertical frame member 1a into the vertical groove 12a of the support block 12 of the transport path 11a. Then, the lower portions of the horizontal frame member 1b and the horizontal frame member 2b are fitted into the lateral groove 12b of the support block 12 designated in advance so as to bridge the transport paths 11a and 11b. After this, the lower portion of the remaining vertical frame member 1a is attached to the support block 1

In this state, each of the frame members 1a and 1b and the rod member 2
The a and 2b are framed and tentatively fixed to the standard shape of the frame 2 with accurate squareness and straightness. In this way, each of the frame members 1a and 1b and the rod member 2a,
The motor 2 of the conveying means B when 2b is fixed to the frame
1 is operated and the framework 2 is conveyed to the nailing means C.

The framework 2 conveyed to the nailing means C moves based on the information of the card put in the control device and moves by the traveling distance determined by the signal from the control device and stops. That is, the first stop position is a position where the horizontal frame member 1b on the transport direction side has reached just beside the nail driving gun 22a. Then, when the frame 2 stops at this position, the air cylinder 25 is driven in response to a signal from the control device, the support portion 24 moves, and the nail driving gun 22b stops at a position facing the nail driving gun 22a. ..

Then, the frame fixing means is activated. First,
The holding portion 31 corresponding to the nailing gun 22a moves upward by driving the air cylinder 31a and holds and fixes the horizontal frame member 1b. Then, the pressing plates 29 and 30 are moved by the driving of the air cylinders 29a and 30a to move the conveying path 11
The upper surface and the side surface of the vertical frame member 1a on the a side are pressed and fixed. Then, the nailing gun 22a operates with the vertical frame member 1a and the horizontal frame member 1b fixed in this manner, and the resin nails are attached to the vertical frame member 1a.
It is driven from the outer side surface of a to the end surface of the horizontal frame member 1b.
Further, after this driving is performed, the nail driving gun is lowered, and nailing is performed again at that position.

At the same time, or before or after this,
Also on the transport path side, each frame member is fixed by operating the frame fixing means, and further the nailing gun 22b is operated to drive the upper and lower two nails into the frame member.

After the nails have been driven into the horizontal frame member 1b in this manner, the frame fixing means is driven to drive the horizontal frame member 1b.
b, The fixation to the vertical frame member 1a is released. Next, the support block 12 travels according to a signal from the control device, the frame 2 moves, and the horizontal cross member 2b on the transport direction side stops at the position just beside the nail driving gun 22a. Then, at this position, the frame fixing and the nailing are repeated again. Further, the same process is repeated, and the horizontal cross member 2 on the upstream side of the transport path is
b and the horizontal frame member 1b are sequentially nailed and fixed to the vertical frame member 1a to complete the connection of the framework 2.

Then, the frame 2 is sent to the next step of applying an adhesive, which is then sent to the step of pasting a face material and the step of pressing to form a panel. In this case, the adhesive applying step, the face material attaching step, and the pressing step are performed in the same manner as in the conventional case. Further, in the case of manufacturing the frame 2 of the pattern having the vertical bars 2a as shown in FIG. 5, as in the case of the previous example, the vertical bars 1a and the horizontal bars 1b corresponding to the desired pattern are produced. , Vertical strips 2a and horizontal strips 2b are prepared, and a guard corresponding to this pattern is put in the control device.

Then, the information input to the card is received,
The control device drives the motor 19b of the conveyance means B,
The worm screw 19 is rotated to laterally move the transport paths 22a and 22c in the direction orthogonal to the transport direction. Then, based on the input information of the control device, the portion where the support block 12 corresponding to the desired frame pattern of the transport chain 14 is fastened is stopped at the working position.

Next, the operator inserts the lower portions of the prepared vertical frame members 1a and horizontal frame members 1b into the vertical grooves 12 of the predetermined support block 12.
It is formed into a rectangular frame shape by fitting it into the a or the lateral groove 12b. Then, the lower portion of the vertical rod member 2a is fitted into the vertical groove 12a of the support block 12 of the transport path 11b between the horizontal rod members 1b. Both ends of the horizontal board 2b are supported by the support blocks 12
It is set between the vertical frame member 1a and the vertical rod member 2a while being fitted in the predetermined lateral groove 12b.

Next, the motor 21 of the carrier means B is rotated to drive the carrier chain 14, and the supporting blocks 12 clamp the frame members 1a and 1b and the rod members 2a and 2b set in an accurate frame. It is conveyed to the hitting means C.

In the frame 2 conveyed to the nailing means C, the lateral frame member 2b on the conveying direction side of the frame 2 is nailed by the controller.
It is stopped at a position just beside 2a. Subsequently, in the same manner as the previous example, the frame fixing means and the nailing gun 22
a and 22c are sequentially operated, and the resin nail is driven from the outer surface side of the vertical frame member 1a to the end surface of the horizontal frame member 1b.

Simultaneously with or before or after the above-mentioned operation, the air cylinder 25 is driven so that the supporting portion 24 moves the center of the muzzle of the staple gun 23 to the horizontal frame member 1b and the vertical rod member 2.
It is located on the joint with a. Then, the air cylinder 26 is driven to move the center of the staple gun 23,
The staple gun 2 is placed so that it is substantially in the center of the width of the vertical strip 2a.
3 is moved and the staple gun 23 is further rotated so that the staples ejected from the staple gun 23 are strung across the horizontal frame member 1b and the vertical frame member 1a. In this way, the staple gun 23 descends and its muzzle comes close to the horizontal frame member 1b and the vertical rod member 1a. Then, the staples are driven in under this state. The staple gun 23 moves up again, and the frame member fixing means is also driven to release the fixing to the horizontal frame members 1b and the vertical frame members 1a.

After the nails and staples have been driven into the horizontal frame member 1b in this way, the transport means B travels again to move the framework 2 so that the horizontal rod member 2b on the transport direction side has the nailing gun 22a. Stop at the position just beside. Then, at this position, the above-described framing process and nailing are repeated again. Simultaneously with or before or after the above-mentioned operation, the air cylinder 21 is driven, and the supporting portion 24 is moved so that the center of the muzzle of the staple gun 23 is moved to one side of the cross member 2b.
It is located on the joint between the vertical strip 2a.

Then, the air cylinder 26 is driven to move the staple gun 23 so that the center of the muzzle of the staple gun 26 becomes substantially the center of the width of the cross member 2b.
Further, the staple gun 23 is rotated by 90 degrees so that the staple gun 23 is driven straddling the horizontal rod member 2b and the vertical rod member 2a. After the position of the staple gun 23 is determined in this way, the staples are driven in the same manner as the above operation. Then, following the stapling of the horizontal strips 2b and the vertical strips 2a, the staple gun 23 again rises and is further moved by the drive of the air cylinder 26, and the other horizontal strips 2b and the vertical strips 2a. A staple is driven into the joint so as to straddle and.

Further, the same process is repeated, and the vertical frame member 1
a and the horizontal bar 2b on the upstream side of the conveying path are fixed by nailing, the horizontal bar 2b and the vertical bar 2a are fixed by stapling, the vertical frame 1a and the horizontal bar 1b are fixed by nailing, the horizontal frame The members 1b and the vertical rod members 2a are sequentially stapled and fixed, and the fixing of the framework 2 is completed. Then, the framework 2 manufactured in this way is sent to the next step as in the previous example.

In the frame manufacturing apparatus having such a structure, by simply fitting the frame members 1a, 1b and the rod members 2a, 2b into the grooves 12a, 12c of the support block 12, the accurate frame shape can be obtained. Since it can be fixed with high accuracy, the work of assembling the wooden panel framework 2 can be facilitated and the accuracy of the framework 2 can be improved. In addition, the transport path 22
a, 22b, 22c, the positions of the support blocks 12, 13 on the transport chain 14, the grooves 12a, 12b, 12c, 13 of the support blocks 12, 13 are adjusted.
The number of a, 13b and the step difference 12d, 12e, 12f of the groove
As a result, it is possible to easily cope with wood panels of various standards.

The cutting apparatus A of the present invention is not limited to this embodiment, and the specific constitutional requirements such as the shape and size of each member can be appropriately changed in the execution. Further, the vertical grooves 12a, 13a and the horizontal grooves 12b, 12c, 13b of the support blocks 12, 13 are determined by the widths of the frame members 1a, 1b and the rod members 2a, 2b. And in the support block 13,
Although only one vertical groove 13a is provided without a step, even if there are two or more vertical grooves, a step is provided so that one vertical groove can be used for rods and boards having different widths. Good.

The steps are not provided stepwise on one side like the lateral grooves 12b and 12c of the support block 12, but steps are provided on both sides so that the frame members 1a having different widths are provided. 1b and the boards 2a and 2b may be set on the same center line. Further, when the support blocks 12 and 13 corresponding to a large number of standards are installed in the transport chain 14 and it is confusing in which groove the frame members 1a, 1b and the rod members 2a, 2b should be fitted, All the grooves corresponding to one standard may be colored in the same color, and the grooves corresponding to the standards different from the above standard may be colored in different colors for each standard.

As described above, according to the present invention,
By simply fitting each rod and rod into the groove of the support block, it can be fixed to the exact shape of the frame with high accuracy, which facilitates the frame work of the frame for wooden panels and improves the accuracy of the frame. Can be improved. In addition, it is possible to easily cope with wood panels of various standards by adjusting the interval between the transport paths, the position of the support block on the transport chain, the number of grooves in the support block, and the like.
