Description

[0001]
[Industrial application fields]
The present invention is used in the field of tatami mat manufacturing. Specifically, it is used in the field of processing that requires folding an edge-less tatami mat along the edge of the long side of the tatami floor.
[0002]
[Prior art]
In general, rimless tatami mats are less in quantity than rimmed tatami mats because of their particularity, and even in the technology required for their production, the mechanization and labor saving of work are delayed compared to those of rimmed tatami mats. On the other hand, in the case of rimless tatami mats, it will be bent at right angles to the direction of weaving on the front (the direction of the weeds), and it tends to be difficult to fold and round the corners compared to folding in parallel to the weaving like a buttock. There is. For this reason, sometimes a bulge appears on the tatami mat after the tatami mat is folded, and it is necessary to correct this. (See Fig. 1 (c))
[0003]
Conventional work will be described. Place the finished tatami mat on the table with the top of the tatami mat face down. Adjust while pulling the tatami mat by hand over the entire length so that the barb of the tatami mat is parallel to the end of the tatami floor.
[0004]
A crease is made by running a thousand sheets on the tatami surface along the edge of the tatami floor. (Fig. 1 (a))
[0005]
High-temperature steam is sprayed using a hand-held nozzle over the entire length of the tatami mat to be folded. Alternatively, a highly permeable surfactant or the like is applied. By doing so, the tatami surface becomes soft and it is easy to bend, and at the same time, it has the effect of reducing the return after bending.
[0006]
The corner of the tatami mat at the corner of the tatami corner is manually stopped. Specifically, the tatami mat of the part is folded and the tatami floor and the tatami mat are fixed with a tucker or the like.
[0007]
Next, the tatami mat is folded while being pressed against the side edge of the floor. The length that can be bent at one time is slightly longer than that of the palm, and it is necessary to repeat this operation many times in order to bend the entire length in order from the end. (FIG. 1 (b)) The bent portions are temporarily fixed at appropriate intervals with a thick waiting needle, a thousand-thick thread, or the like. When the folding of the full length is finished, the certainty of the folding state is checked, and for the loose part, the front and rear temporary fixings are once released and then bent again to perform temporary fixing. After this, the tatami mat and the floor are fixed with a tucker or the like. Sometimes sewn after tucking. This is the end of the side bending process.
[0008]
The other side folding operation itself is the same as the above-described procedure. However, loosening may occur along the tatami floor side end when the first side is folded, and the tatami surface may be swollen over the entire length. (FIG. 1 (c)) In order to eliminate the bulge of the tatami mat before folding the other side, the tatami mat at one end, which is strongly pulled over the entire length, was again bent and fixed to the tatami floor.
[0009]
[Problems to be solved by the invention]
Since a series of operations are manual operations, it takes time, and there is a case where the tatami surface is swollen (the tatami surface is lifted from the floor) because the folds are not sufficiently attached at the time of folding and the looseness comes out. In addition, the bent part is not exactly fixed and looks rounded and the appearance is not good. Another problem is that it takes time to carry out the return work for this correction and is wasteful.
[0010]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a series of folding work of a tatami table of an edgeless tatami mat is mechanized, and further, the operation of the machine is automated to improve the working efficiency, and the bending accuracy is improved to improve the folding part. There is a need for measures to prevent the occurrence of roundness and looseness of tatami mats.
[0011]
In order to embody the above-mentioned necessary means, the invention according to claim 1 is arranged such that a tatami mat that has been sewed is placed on the table with the tatami table facing downward, and the folding positioning means descends so that After deciding the folding position of all or most of the long side and further lowering the tatami holding means to fix the tatami, the tatami holding, the positioning plate and the table are lowered by the same distance and placed on the table. This is a machine that folds the folding part of the tatami mat that protrudes from the floor of the tatami mat so that a fixed folding plate of approximately the same length as the table provided in parallel to the side edge of the tatami mat is pushed up from below. Further, the above means operate automatically and thus save labor. Further, since the positioning plate is located between the side surface of the tatami floor and the tatami surface (the protruding portion), the folding is surely performed by the relative vertical movement with the outer folding plate. Furthermore, since the tatami presser presses the tatami mat over the entire length even when folding the tatami mat, the tatami mat does not loosen or bulge.
[0012]
In addition , the table on which the tatami is placed and the tatami presser for preventing the movement of the tatami are synchronized to move in the same direction and the same distance. When the tatami presser descends from the origin, presses the tatami mat and further descends, the table is pushed down by the cylinder stroke of the tatami presser together with the tatami mat placed. This operation can be performed by making the cylinder thrust of the tatami presser larger than the thrust of the table raising cylinder. The maximum stroke from the origin of the tatami presser is up to the reference level, and is constant regardless of the tatami thickness. Even if the lower surface of the tatami floor is pushed down by this means, it finally always stops at the reference level.
[0013]
Also , by integrating the support structure of the positioning plate for folding the tatami table with the table, when the table is raised and lowered, the positioning plate can also be raised and lowered by the same distance. If the positioning plate is set on the upper surface of the protruding tatami surface along the side of the tatami floor, the folding is performed as the table is lowered. Since the positioning plate performs a predetermined operation only by instructing the operation of the table, it is efficient.
[0014]
The invention according to claim 2 is a means for performing a folding operation by folding the tatami table not only at the upper corner of the tatami mat but also at the thin tatami floor, with the lower corner continued to the upper corner. The folding plate of approximately the same length as the table is swung around the lower rotation axis by the support arms at both ends of the folding plate, so that the upper folding plate is at the height of the reference level (the fold on the table). It moves to the tatami side at the lower corner position and bends the tatami table so that it is pushed in at the lower corner of the tatami mat. Since the lower surface of the tatami lowered by the tatami press is always at the reference level in the final state, the operation of claim 2 is established.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
The structure of the edgeless tatami surface folding machine 1 of the present invention will be described with reference to FIGS. A tatami mat that has been sewn is placed with the tatami mat A facing down, and a plurality of bar rollers 5 arranged in parallel to move to a predetermined position in the length direction of the tatami mat, and the bar roller 5 with a bearing The table 6 supported through the tatami mat, the positioning plate 2 that can be moved up and down to determine the folding position of the tatami mat, the tatami presser 3 that can be moved up and down to fix and hold the tatami after the folding position is determined, When the table 6 is pressed, the air cylinder 21 descends while supporting the table 6 by the stroke, and the stroke of the air cylinder 21 is a means for the entire table to descend uniformly. When the link 23 and the connecting rods 24 and 25 that transmit to the support position, and the tatami mat and the table 6 are lowered, the tatami mat table A is arranged parallel to the surface of the positioning plate 2 and the tatami mat A is bent at the upper corner of the tatami mat. As a means of horizontally folding the fixed folding plate 7 and the tatami mat table A at the lower corner of the tatami mat, the tatami mat table A is pressed against the back of the tatami mat floor B (upper surface in FIG. 2). The edgeless tatami mat folding machine 1 according to the present invention is composed of the folding plate 8, the air cylinders 16 to 21 as drive sources of the above-mentioned means, the operation-indicating foot switch 30, the initial operation panel 32, and the like. Is done.
[0016]
The procedure of the operation in which the machine of the present invention configured as described above folds the edgeless tatami mat A is as follows.
[0017]
Before setting the machine according to the present invention, the tatami mat A is cut to a predetermined width, and the four corners of the tatami floor B are cut out (see the corners of the tatami floor B in FIG. 5). In the case of a cocoon table, it is softened by applying superheated steam as shown in FIG. 5 to the folded tatami surface. In the case of a resin table, the cocoon heated at the folding part of the tatami table A It is necessary to make preparations such as making creases using. In addition, as a preparation on the machine side, clean air is connected from a compressor (not shown), the power is turned on, and whether the tatami floor is a normal floor or a thin floor, etc. is performed with a button (not shown) on the operation panel 32. . Usually, the thickness of the normal floor is 40 mm to 60 mm, and the thickness of the thin floor is 12 to 25 mm.
[0018]
Step 1: With the tatami mat A facing down, one side of the bent portion of the tatami mat A is on the front side of the machine 1 (left side in FIG. 2), placed on the roller 5 and laid from the side (left or right in FIG. 3). And put it in the center of the machine.
[0019]
Step 2: Set the tatami floor B side end within a few mm from the table end (to the right in FIG. 2).
[0020]
Step 3: If the positioning plate lowering button on the operation panel 32 is continuously pressed, the positioning plate 2 descends and stops about 5 mm above the tatami table A of the bent portion on the table 6.
[0021]
Step 4: Hold the folded part of the tatami mat A until the end of the tatami floor B contacts the positioning plate 2 and pull it forward. When the foot switch 30 is stepped on, the positioning plate lower limit adjustment 22 is retracted. As shown in FIG. Further down, press the tatami mat A. Thereafter, in the case of a synthetic resin tatami mat, it is warmed with a manual heat gun (not shown) or steam until the tatami mat A becomes soft.
[0022]
Step 5: When the foot switch 30 is stepped on, the tatami presser 3 is lowered, and the tatami mat, the table 6 and the positioning plate 2 are also lowered together after coming into contact with the back of the tatami floor B. The side edge passes up and down with the folding plate 7 and the tatami mat A is folded along the tatami floor B as shown in FIG.
[0023]
Since the contents of the work process differ between the case of the thin tatami floor B and the normal tatami floor B after step 6, the operation procedure will be described separately for each. That is, the thin tatami floor B is bent at the lower corner as well as the upper corner, and the side edge of the tatami mat A is stapled to the back surface of the tatami floor B with a tucker. On the other hand, in the case of the ordinary tatami floor B, there is no lower corner bend, and the side end of the tatami mat A is stapled to the side surface of the tatami floor B with a tucker.
Step 6 (in the case of a thin tatami floor): When the foot switch 30 is stepped on, the positioning plate 2 rises, and the folding plate is prepared so that it can be pushed into the back of the tatami floor B in the next step.
[0024]
Step 7 (in the case of a thin tatami floor): When the foot switch 30 is further stepped on, the folding plate 8 is operated by the air cylinder 20, and the tatami mat A is folded at the lower corner of the tatami and pressed against the back of the tatami floor B as shown in FIG. .
[0025]
Step 8 (in the case of a thin tatami floor): The folded tatami mat A is stapled on the back of the tatami floor B with a tucker (not shown) at an appropriate interval over the entire length of the tatami mat.
[0026]
Step 9 (in the case of a thin tatami floor): When the foot switch 30 is stepped on, the folding plate 8 moves backward.
[0027]
Step 6 '(in the case of a normal tatami floor): When the foot switch 30 is stepped on, the folding plate 8 is moved by the air cylinder 19 to move away from the side surface of the tatami floor, ensuring a space for the tucker to enter the side surface of the tatami floor and positioning plate 2 rises so that the work of adhering the side surface of the tatami floor B and the tatami surface A in the next step can be performed.
[0028]
Step 7 ′ (for a normal tatami floor): The folded tatami mat A is stapled on the side of the tatami floor B with the tucker over the entire length of the tatami mat.
[0029]
Step 10 (in the case of a thin tatami floor), Step 8 ′ (in the case of a normal tatami floor): When the foot switch 30 is stepped on, the tatami presser 3 is raised.
[0030]
With the above operation, the folding of one of the tatami mats A ends. By reversing the tatami and folding the other side in the same procedure from step 1 above, all the folding of the edgeless tatami mat A is completed. In the case of a thin tatami floor, there is not enough space to fix the tatami mat on the side of the tatami floor with a tucker, so it is folded to the back of the tatami floor and secured with a tucker. In the case of a normal tatami floor, it is thicker than a thin tatami floor, and it is not necessary to bend the tatami table A to the back of the tatami floor B because the tatami mat A can be secured to the side of the tatami floor B with a tucker. It can be folded in the same procedure as folding a tatami mat.
[0031]
【The invention's effect】
As is clear from the description based on the above embodiment, according to the tatami mat folding machine 1 for an edgeless tatami mat of the present invention, the input operation is not performed until the folding of the tatami mat A is finished after the tatami is set on the machine 1. It is sufficient that the switch 30 is stepped on, the folding of the tatami mat A can be reliably performed in a short time, and the tatami mat does not bulge. Furthermore, the operation of the machine is simple and does not require any skill, and the work for returning is eliminated and the workability can be improved.
