Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a tatami floor which is laid on a tatami floor and sewn a frame (both ends in the longitudinal direction of the tatami). It relates to a device to be involved.

[0002]

2. Description of the Related Art As shown in FIG. 7 (a), when a tatami mat is sewn on a tatami mat by superimposing the tatami mat on the tatami mat, the tatami mat 4 is placed on the tatami mat 4 and the tatami mat 3 is tensioned. After the tatami mat 3 is pressed on the tatami mat 2 by the push plate 5 so that the tension of the tatami mat 3 is not loosened, as shown in FIG. There has been conventionally proposed a device that bends the end 31 of the tatami table 3 downward along the frame 21 in contact with the frame 21.

[0003]

In such a conventional apparatus, the end 31 of the tatami mat 3 cannot be wound in a U-shape along the frame 21 to the back side of the tatami floor 2, so that the end 31 of the tatami mat 3 must be manually wrapped. As shown in FIG. 8, sewing was performed with a sewing thread 7 using a sewing machine.

Therefore, the present invention has been conceived in order to obtain a device for automatically winding the end 31 of the tatami mat 3 along the frame 21 to the back side of the tatami floor 2 without such manual operation. .

[0005]

A device for winding a tatami mat into a frame according to the present invention comprises a tatami mat 4 on which a tatami mat floor 2 is placed and a tatami mat 3 superimposed on the tatami mat floor 2 in the vicinity of the frame 21. The push plate 5 to be attached and the end 31 of the tatami table 3 protruding from the frame 21
And a pressing device 1 that presses against the side surface of the frame 21 and then presses against the back surface of the frame 21 to wind in a U-shape.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in the perspective view of FIG. 1, a device for winding a tatami mat into a frame according to the present invention comprises a tatami mat 4 on which a tatami mat 2 is placed and a tatami mat 3 superimposed on the tatami mat 2. And a winding device 1 attached to the pressing plate 5.

The winding device 1 includes a rotating shaft 12 rotatably supported by a bearing 11 provided on the push plate 5, a pinion 13 fixed to the rotating shaft 12, and a bracket 14.
And a rack 17 meshed with the pinion 13 and driven by a piston of an air cylinder 18 and a bracket by bolts.
14 and three pressing guide members 15 made of leaf springs
a, 15b and 15c.

As shown in the side view of FIG.
The three pressing guide members 15a, 15b, 15c fixed to
Each has a rounded tip bent outward and a middle section bent inward, differing in length.

When performing frame stitching with the device configured as described above, the tatami floor 2 is positioned and placed on the tatami floor 4, and the tatami table 3 is overlaid on the tatami floor 2 while being tensioned. Then, the tatami mat 3 is pressed against both ends of the tatami floor 2 by the push plate 5. Then, when the air cylinder 18 is operated and the rack 17 is pushed by the piston, the rotating shaft 12 is rotated via the meshed pinion 13.

[0010] By the rotation of the rotating shaft 12, three pressing guide members 15a, 15 fixed to the rotating shaft 12 via the bracket 14 are provided.
The b and 15c rotate from the state shown in FIG. 2 to the state shown in FIG. 3, and first press the upper side surface of the frame by the short pressing guide member 15a, and then press the intermediate portion of the frame by the pressing guide member 15b. The side is pressed, and finally the back of the frame is pressed by the long pressing guide member 15c.

Each of the three pressing guide members 15a, 15b, 15c
When the tatami mat 3 is sequentially pressed against the frame, as shown by an arrow A in FIG.
, So as to extend the end 31 along the frame 21.

In this way, after the end 31 of the tatami mat 3 is wound along the frame 21 to the back side of the tatami floor 2, sewing by the sewing machine is started. When the sewing machine has sewn several stitches, the rotary shaft 12 is rotated in the opposite direction by the air cylinder 18 to raise the pressing guide members 15a, 15b, 15c to the state shown in FIG.
It does not hinder the sewing operation of the sewing machine. Normally, when the end 31 of the tatami table 3 is held until the start of sewing, after that, the end 31 of the tatami table 3 is caught by the movement of the sewing machine.

(Other Embodiments of the Invention) In the embodiment described above, the winding device 1 is installed on the push plate 5 in order to cope with fluctuations in the thickness of the tatami floor 2. For example, , The tatami mat 4 or the like may be installed at a reference position.

The pressing guide members 15a, 15 of the winding device 1
Although leaf springs are used for b and 15c, they may be composed of elastic wires or rods.

Further, as shown in the sectional view of FIG.
As a pressing guide member for pressing the end portion 31, an elastic body 15 s such as a sponge, which changes in volume, is housed in a channel-shaped frame 15 t.

Further, as shown in the sectional view of FIG. 5, an elastic sheet such as a rubber sheet or a rubber cord is provided at the opening of the channel-shaped frame 15t as a pressing guide member for pressing the end 31 of the tatami mat 3. Alternatively, it can be configured by stretching a string-like body 15 g. In this case, if the frame 15t is configured to rotate until the front end of the frame 15t hits the back surface of the tatami floor 2, the end 31 of the tatami table 3 is irrespective of the thickness of the tatami floor 2.
Can be rolled along the frame 21.

In each of the embodiments described above,
Although the pressing guide member of the winding device 1 is rotated around the rotary shaft 12, as shown by an arrow in FIGS. 6A to 6C, a mechanism that moves around the frame 21 of the tatami floor 2 is adopted. However, the same operation can be performed.

[0018]

As is clear from the description based on the above embodiment, according to the apparatus for winding a tatami mat into a stile according to the present invention, the end 31 of the tatami mat 3 is moved to the back side of the tatami floor 2 at the start of the stitching. Because it can keep the state of being rolled into a U-shape,
You can save manpower.
