Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention is used in the field of tatami manufacturing. Specifically, it is used in a processing field that requires a tatami mat for tatami mats to be bent along the edges of the tatami mat floor.

[0002]

2. Description of the Related Art In general, tatami-less tatami mats are less quantitatively produced than tatami mats due to their specialty, and the technology required for the production of tatami mats is slower in mechanization and labor-saving than in tatami mats. Was. On the other hand, in the case of non-tatami mats, it is bent at a right angle to the weaving direction of the table (the direction of the rush), but the corners tend to be more difficult to bend than to bend parallel to the weaving like a frame. For this reason, a swelling may appear on the tatami surface. (See Fig. 1 (c))

[0003] A conventional operation will be described. Lay the tatami mat on the table with the frame stitched upside down. Adjust the tatami mat by hand by pulling it over the entire length so that the ridges of the tatami mat are parallel to the end of the tatami floor.

A folding habit is formed by running an awl or the like on the tatami surface along the tatami floor end. (FIG. 1 (a))

[0005] High-temperature steam is sprayed using a hand-held nozzle over the entire length of the tatami mat in the area to be bent.
Alternatively, a highly permeable surfactant or the like is applied. By doing so, the tatami surface becomes soft, and the bending operation becomes easy, and at the same time, there is an effect of reducing springback (return) after bending.

The corner of the tatami mat at the corner of the tatami mat is manually stopped. Specifically, the tatami mat of the part is bent, and the tatami mat and the tatami mat are fixed to each other with a tucker or the like.

Next, the tatami mat is bent while being pressed against the side edge of the floor. The length that can be folded at one time is slightly longer than the palm, and it is necessary to repeat this operation many times to bend the entire length in order from the end.
(FIG. 1 (b)) The bent portion is temporarily fixed at an appropriate interval with a thick waiting pin, awl, or the like. When the bending of the entire length is completed, the reliability of the folding condition is checked, and the loose portion is temporarily released before and after the temporary fixing, and then bent again to perform the temporary fixing. After that, the tatami mat and floor are fixed with a tucker. In some cases, sewing may be performed after hitting a tucker. This completes the bending of one side.

[0008] The bending operation of the other side itself is the same as the above-described procedure, but the first side is loosened along the side of the tatami floor when the first side is bent, and the tatami surface bulges over the entire length. (FIG. 1 (c)) In order to eliminate the swelling of the tatami table before bending the other side, the tatami table at the other end was firmly pulled again over the entire length and the tatami table was fixed to the tatami floor.

[0009]

A series of operations are performed by hand, which takes a long time, and the surface of the tatami swells due to the fact that the tatami does not have a sufficient habit of folding and becomes loose (the tatami mat rises from the floor). Often occur. Further, the bent portion may not be properly determined and may have a rounded appearance, so that the appearance may not be good. Another problem is that the return work for this correction requires time and is wasteful.

[0010]

SUMMARY OF THE INVENTION The efficiency of bending and the accuracy of bending are improved by mechanizing a series of bending operations of a tatami table of a borderless tatami mat. Prevent tatami mats from bulging.

[0011] The setting of the position of the folding line on the tatami mat and the folding operation can be performed in a reliable manner, and these operation steps can be performed once over the entire length of the tatami mat.

In order to prevent the tatami surface from bulging or wrinkling after the bending operation on one side.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION A folding machine 1 according to the present invention for non-tatami mats.
Is a table 8 on which both the tatami table A and the tatami floor B are stitched together, a positioning plate 2 for determining the folding position of the tatami table at once along the entire length along the side edge of the tatami floor B, and this positioning plate 2 The function surface is constituted by a bent plate 5 for bending the tatami table while sliding the tatami table along. The positioning plate 2 and the bending plate 5 are each an air cylinder for lifting and lowering (not shown).
Is linked to In addition, the floor press 3 for fixing the tatami table A and the tatami floor B at predetermined positions on the table 8, and the tatami table side push for pushing the floor end (including the tatami table B) for preventing the floor end of the tatami table A from bulging. 7 and a floor stopper 6 for supporting the opposite side of the floor via the positioning plate 2 when pushed sideways, and a wide floor presser 4 for eliminating the swelling of the tatami mat B when pushed sideways. ing. (FIG. 2) (FIG. 3) Both are driven by an air cylinder (not shown). The operation of the machine and its procedure are also automatically controlled, and the foot switch 10
The operation of each step is performed automatically just by stepping on.

The operation procedure of the tatami-face folding machine 1 according to the present invention will be described.

Step (1): The tatami mat A with the frame stitched is placed in the center of the machine with the tatami mat A facing down. Adjust by hand so that the floor edge is within a few mm from the edge of the table.

Step (2): When the foot switch 10 is depressed, the positioning plate 2 drops to about 100 mm above the table and stops once. When the foot switch 10 is further depressed, the positioning plate 2 is lowered. At this time, the positioning plate 2 is 4 m from the tatami table A.
Stop at about m.

Step (3): In this state, the tatami mat A is pulled by hand until the tatami mat hits the positioning plate 2.

Step (4): When the foot switch 10 is depressed, the floor presser 3 is lowered and pressed against the table 8 so that the tatami does not move.

Step (5): When the foot switch 10 is depressed, the positioning plate 2 descends, and the end comes into contact with the tatami table A and stops. (FIG. 4)

Step (6): Next, the steam produced by the apparatus different from the present invention is sprayed over the entire length of the tatami table A outside the tatami floor end with a hand-held nozzle. (FIG. 5) As a result, the tatami table A becomes soft and easy to bend.

Step (7): When the foot switch 10 is depressed, the bending plate 5 moves up and down. (FIG. 6) In this vertical movement, the bent plate 5 moves up and down while sliding on the outside of the tatami table A at the floor end a preset number of times. By this operation, the tatami table A is bent by the folding plate 5 along the positioning plate 2 to have a folding habit. With this series of operations, the tatami table A is uniformly bent over the entire length. When the bending is slightly insufficient, the foot switch is depressed again to operate the bending plate 5.

Step (8): When the foot switch 10 is depressed, the positioning plate 2 rises to the upper limit and stops.

Step (9): Next, corner stop processing is performed manually. (FIG. 7)

Step (10): When the foot switch is depressed, the bent plate 5 is raised, and the tatami table A is brought into the state of being along the tatami floor B.

Step (11): In this state, the tatami mat is pressed against the back of the tatami mat by hand, and an operator holds the tucker at appropriate intervals to perform stapling.

Step (12): The foot switch is stepped on to raise the floor presser 3 and the bent plate 5 is lowered. Thus, the folding operation of the tatami table A on one side of the tatami floor is completed.

Step (13): The direction of the tatami mat is rotated by 180 degrees, and the other side is arranged so as to be within a few mm from the edge of the table.

Steps (14), (15), (16):
The operation is performed in the same procedure as steps (2), (3) and (4).

Step (17): When the foot switch 10 is depressed, the floor stopper 6 rises and turns, and is set so as to contact the outside of the positioning plate 2. (FIG. 8)

Step (18): When the foot switch 10 is depressed, the floor presser 3 once rises and stops.

Step (19): When the foot switch is depressed, the tatami mat horizontal push 7 horizontally pushes the tatami mat floor end that has been bent.
(FIG. 9) By this operation, the swelling of the floor end portion of the folded tatami table A is corrected, and the tatami table A is not loosened. At this time, the floor stopper on the opposite side is supported by the floor stopper 6 via the positioning plate 2 so that the whole tatami does not move. (FIG. 8)

Step (20): When the foot switch 10 is depressed, the floor presser 4 descends and presses (presses) the tatami mat. By this operation, the tatami is fixed in a state where the bulge of the tatami table A has disappeared. Further, the floor retainer 3 descends to hold down the tatami mats so that the tatami mats are not loosened.

Step (21): When the foot switch 10 is depressed, the floor stopper 6 turns, descends and returns to the origin.

Steps (22) to (29): The same procedure and operation as those in steps (5) to (12) are performed, and the folding operation of the tatami table A is completed.

(Other Embodiments of the Invention) When the tatami table A is woven with chemical fibers (for example, polypropylene fibers), it is more difficult to bend because the elastic modulus is higher than that of rush. In order to solve this, by making the positioning plate 2 also have a function of a heater, it is possible to perform the creasing in the above-mentioned step (5), and the tatami table A is easily folded. Specifically, a predetermined temperature (150 to 200 degrees Celsius at which the chemical fiber is slightly melted) before step (5)
Place the heated positioning plate 2 on the tatami table A and melt it about half the thickness of the tatami table. The melted upper half fibers are not cut but are welded to the lower fibers so that they are not cut even when bent.
In this way, groove-like folds are made along the entire length of the tatami floor. Further, in the case of a tatami mat made of chemical fibers, the folds can be reliably formed only by the positioning plate serving as a heater, so that there is no need to blow steam.

[0036]

According to the present invention, the folding operation of the tatami table A with no tatami mats can be performed with a high degree of accuracy only with a small amount of manpower and instructions for easy machine operation. In addition, the swelling of the tatami table A and the rounded bend at the floor end, which have occurred during the conventional bending operation, can be eliminated, and the time required for the bending operation can be greatly reduced.
