Example An example of the present invention will be described below, but the basic method arrangement device is the same as the method and device described above, and the description thereof will be omitted. In particular, the improvement in the present invention will be described below. Only the points will be described with reference to the drawings.

That is, the improvement in the present invention is that the pressing device 30 after supplying the adhesive of the gauze mounted on the moving table movable in the XY directions.
0 and the cutting device 400 are different, and a unit portion mounted on the moving table device 9 including the adhesive applying device 10 and the drying device 11 will be described in detail below.

15 and 16 are side views of the unit portion mounted on the upper side of the moving table 87, and FIG. 17 is a plan view of the same.

As shown in FIG. 15, the pressing device 300 attaches a cylinder 303 to a frame 302 which is attached to the upper side of a moving table 87 via a lever rod 301, and a supporting rod to this cylinder 303 via a connecting portion (rotary joint) 304. 305 is vertically moved and rotatably connected, and a pressing roller 306 having a plurality of rotating rollers 307 is attached to the tip of the supporting rod 305.

The support rod 305 is rotatably supported by the bearing 315 of the moving table 87, and the gear 308 attached to the support rod 305 is meshed with the drive gear 310 of the drive motor 309.

As shown in FIG. 16, the cutting device 400 connects a supporting rod 403 to a cylinder 401 attached to the pedestal 302 via a connecting portion (rotary joint) 402 so as to be vertically movable and rotatably, and cuts at the tip of the supporting rod 403. And a gear 406 attached to the support rod 403. Further, a movable cutter 87 is fixedly attached, and a bearing 405 of the support rod 403 is provided on the moving table 87 on the upper side.
Is meshed with the drive gear 310 of the drive motor 309. A cylindrical cover 407 is attached to the inactive position (top dead center) of the cutter 404.

Reference numeral 500 denotes a heater that constitutes the drying device 11, and the coating device 1
Regarding 0, it has the same configuration as the coating device 10 in the above-mentioned cloth tensioning device, and in the drawings, the same components are denoted by the same reference numerals and the description thereof is omitted.

Therefore, by the constitution other than the device shown in FIGS. 15 and 16 in the constitution of the device shown in FIGS. 1 to 14 described above,
After performing the same work, after the bond application work by the application device 10 and the forced drying work using the heater 500 of the drying device 11 are completed (or at the same time), the moving table 87 is moved to the XY position of the moving table device 9. Directional motion
It moves to a predetermined position, and along with the movement of the moving table 87, the cylinder 303 is operated to lower the support rod 305 to bring the pressing roller 306 into contact with the frame surface 4a of the frame body 4. At this time, the pressing roller 306 is oriented in the length direction of the frame surface 4a (for example, in the X direction).
Therefore, under this condition, the moving table 87 is moved in the X direction, and the pressure roller 306 is forced to press the gauze 2 against the frame surface 4a of the frame body 4.

Further, after the pressing of the frame surface 4a of the first frame of the four frames of the frame body 4 is completed, the cylinder 303 is operated and the supporting rod is operated before traveling on the moving table 87 in the Y direction. The pressure roller 306 is once raised to the top dead center together with 305, and the drive motor 309 is operated to rotate the support rod 305 through the gears 310 and 308 by a predetermined amount (90 degrees) to displace the direction of the pressure roller 306 in the Y direction. Then, the cylinder 303 is operated again to lower the pressing roller 306, and the second roller is moved to the frame surface 4a of the frame.
After the completion of this, the pressing roller 306 is displaced in the X direction again according to the above-mentioned operation to perform the pressing work of the frame surface 4a of the third frame, and after this is completed,
It is again displaced in the Y direction to perform the pressing work on the frame surface 4a of the fourth frame. The traveling of the pressing roller 306 is due to the movement of the moving table 87. Further, if necessary, the pressing work of each frame of the frame body 4 can be repeated not only once but several times.

After the work of pressing the gauze 2 against the frame surface 4a of each frame of the frame body 4 by the pressing device 300 is completed, the cylinder 303 is operated to raise the support frame 305 and return to the original position.
01 is operated to lower the cutter 404 of the cutting device 400.

At this time, the cutting device 400 is set in advance to a predetermined cutting position by moving the moving table 87,
The cutter 404 is lowered to the outer peripheral side of the frame body 4.

The orientation of the cutter 404 corresponds to the cutting direction, that is, the traveling direction of the moving table 87. For example, when traveling in the X direction, the orientation of the cutter 404 is also oriented in the X direction. Therefore, after the cutting of the gauze 2 on the outer peripheral side along the X-direction frame of the four frames of the frame body 4 is completed, the cylinder 401 is operated to raise the cutter 404 to the top dead center and the pressing roller. Drive motor 309 similar to 306
The supporting rod 403 through the gears 310 and 406 by a predetermined amount (90
By rotating the cutter 404, the cutting direction of the cutter 404 is displaced in the Y direction, and the outer peripheral side of the frame in the Y direction of the frame 4 is cut. It can be performed by the cutter 404.

The displacement of the pressing roller 306 and the cutter 404 in the pressing direction and the cutting direction is driven by the drive motor 309.
The support rods 305 and 403 are rotated by a predetermined amount through the gears 308 or 406, and the frame body 4 is a rectangle (or a quadrangle in some cases), and the left and right and front and rear frames (four frames). The pressing direction and the cutting direction along the line can be changed by converting the moving table 87 into the XY direction and by rotating and displacing it by 90 degrees (for the length of each frame, the moving table 87 in the XY direction). It can be preset depending on the distance traveled to).

Therefore, the drive motor 309 is generated by a signal (X-direction travel completion signal) at the time when the moving table 87 travels, for example, the length of the frame along the X direction among the frames of the frame body 4.
The rotary blades 315 and 415 fixed to the lower part of the support rods 305 and 403 are attached, and four projecting pieces 316 and 416 are provided on each of the rotary blades 315 and 415 at every 90 degrees. And
By attaching proximity switches 317 and 417 facing the rotary blades 315 and 415 to the support frame 302, one of the four protrusions 316 and 416 is detected by the proximity switches 317 and 417, and the drive motor 309 is stopped by the detection signal. The pressing direction and the cutting direction of the pressing roller 306 and the cutter 404 can be displaced in the Y direction, and the displacement direction can be controlled in the X direction and the Y direction in the same manner as the traveling direction of the moving table 87 in the same manner. However, the pressing roller 306 and the cutter 404
The direction change can be performed not only by an electric signal but also by a mechanical means using a Geneva gear or the like.

Incidentally, during the above-mentioned work, the work necessary for the upholstery work is carried out by the same work as that of the apparatus shown in FIGS. 1 to 14, and the work after cutting is also the same.

EFFECTS OF THE INVENTION According to the present invention, it is possible to carry out the cloth tensioning work on the frame body easily and quickly by the automatic work without unevenness of the cloth tensioning accuracy, and it is possible to greatly improve the conventional cloth tensioning workability. .

Further, in particular, it is possible to eliminate unevenness in the fixation of the gauze on each frame surface of the frame body, and to accelerate the cutting and simplify the cutting device.
