Description
本発明は、縁無畳の畳表を畳床の側面に沿って折り曲げる縁無畳用畳表折り曲げ機である。詳しくは、位置決め板を畳表の折り曲げ位置に押しつけることにより、畳床の側面に沿う位置に折りくせをつけ、畳表を畳床の側面に沿わせて折り曲げる縁無畳用畳表折り曲げ機である。 The present invention is a rimless tatami mat folding machine that folds a rimless tatami mat along the side surface of a tatami floor. More specifically, it is a rimless tatami mat folding machine that bends the tatami mat along the side surface of the tatami floor by pressing the positioning plate against the folding position of the tatami mat floor to make a fold along the side surface of the tatami mat floor.
框縫い工程が済み、框方向の畳床に畳表が縫われた畳を、畳表を下にしてテーブルの上に載置し、畳表を折り曲げるための位置決め板が下降して折り曲げ位置を決め、床押さえが下降して畳を保持し、位置決め板が更に下降して畳を保持した状態で、折り曲げ板が上下に複数回昇降することにより、折りくせを付けた後に、畳床からはみ出した畳表の折り曲げ部を、畳床の側面側に折り曲げる縁無畳用畳表折り曲げ機は従来より具現化されている。
After the sewn process is completed, the tatami mat with the tatami mat sewn on the tatami floor in the direction of the stile is placed on the table with the tatami mat face down. With the retainer lowered to hold the tatami mat, and the positioning plate further lowered to hold the tatami mat, the folding plate moves up and down multiple times to make a fold, and then the tatami mat that protrudes from the tatami floor. Conventionally, a tatami mat folding machine for rimless tatami mats that bends a bent portion to the side surface side of a tatami floor has been embodied.
従来技術の縁無畳用畳表折り曲げ機において折りくせを付ける方法を図5を用いて説明する(図5は特開2001-227143号の図6と同じ図である)。
折り曲げ板(51)がテーブル(53)よりも下方から上昇し、位置決め板(52)と
折り曲げ板(51)により畳表Aを挟み込んで上方へ折り曲げた後に折り曲げ板(51)は下降する。予めセットされた回数だけ折り曲げ板(51)が昇降し、位置決め板(52)に沿って畳表Aが折り曲げられて折りくせを付けられるものである。
しかし、この方法の場合、位置決め板(52)の厚みの分、畳床Bの側面よりも外側の位置に折りくせをつけてしまう。
折りくせの位置が位置決め板(52)の厚みの分だけ外側へずれた状態で折り曲げられた場合、折り曲げられた畳表Aは、厳密には、畳床Bの側面に沿っておらず、完成した縁無畳の表面寸法は僅かではあるが大きいものとなり、部屋に敷き込んだ場合に隣接する縁無畳が押し合い、畳表Aが浮いてふくろ状になる。という課題を残すものである。
このような背景から畳床Bの側面に沿う位置に折りくせを付けて、畳表Aを畳床Bの側面に正確に沿わせて折り曲げる縁無畳用畳表折り曲げ機が要望されている。
A method of making a fold in a conventional rimless tatami mat folding machine will be described with reference to FIG. 5 (FIG. 5 is the same diagram as FIG. 6 of Japanese Patent Application Laid-Open No. 2001-227143).
The folding plate (51) rises from below the table (53), the tatami table A is sandwiched between the positioning plate (52) and the folding plate (51), and the tatami table A is bent upward, and then the folding plate (51) descends. The folding plate (51) moves up and down as many times as the preset number of times, and the tatami mat A is bent along the positioning plate (52) so that it can be folded.
However, in the case of this method, a fold is formed at a position outside the side surface of the tatami floor B by the thickness of the positioning plate (52).
Strictly speaking, the folded tatami mat table A did not follow the side surface of the tatami floor B and was completed when the folded position was bent outward by the thickness of the positioning plate (52). The surface size of the rimless tatami mat is small but large, and when it is laid in a room, the adjacent rimless tatami mats are pressed against each other, and the tatami mat table A floats and becomes a bag shape. It leaves the problem.
From such a background, there is a demand for a tatami mat folding machine for rimless tatami mats, which bends the tatami mat A exactly along the side surface of the tatami floor B by making a fold at a position along the side surface of the tatami floor B.

As shown in FIG. 2B, the cross section of the positioning plate (2) is composed of a wedge surface (2b) forming a wedge shape and a flat surface (2a) having a flat tip.
続いて、本発明の縁無畳用畳折り曲げ機(1)の動作を説明する。
畳作業者により、框縫い工程が済み、畳床Bの框方向に畳表Aが縫われた畳が、畳表Aを下にしてテーブル(5)の上に載置され、制御盤(7)に設けられた表示操作部(図示せず)により、予め定められたシーケンスの実行が指示される。
Subsequently, the operation of the edgeless tatami folding machine (1) of the present invention will be described.
A tatami mat that has been sewn by a tatami mat worker and has a tatami mat table A sewn in the stile direction of the tatami floor B is placed on the table (5) with the tatami mat table A facing down and placed on the control panel (7). A display operation unit (not shown) provided is instructed to execute a predetermined sequence.
位置決め板昇降エアリンダ(8)により位置決め板(2)が予め定められた定位置まで下降した後、畳作業者により、畳が位置決め板(2)の方向に押しつけられることにより、畳床Bの側面が全長にわたって位置決め板(2)に沿って当接する。 After the positioning plate (2) is lowered to a predetermined fixed position by the positioning plate elevating air linder (8), the tatami mat is pressed in the direction of the positioning plate (2) by the tatami worker, so that the side surface of the tatami floor B Abuts along the positioning plate (2) over the entire length.
畳床Bの側面が位置決め板(2)に当接した状態で、床押さえエアリンダ(12)により、床押さえ(3)が下降し、畳をテーブル(5)に押さえつけて、この後の動作において位置がずれないように保持される。 With the side surface of the tatami floor B in contact with the positioning plate (2), the floor retainer (3) is lowered by the floor retainer air linder (12) to press the tatami mat against the table (5), and in the subsequent operation. It is held so that it does not shift.
この状態で、折りくせつけ動作を実行する。図3(a)を用いて、折りくせを付け動作を説明する。
床端押さえエアリンダ(13)により、床端押さえ(4)が下降し、畳床Bの端をテーブル(5)に押さえつけて、折りくせつけ動作中に畳床Bの端が浮かないように保持し、折り曲げ板(6)は、天面がテーブル(5)の天面と同じ高さとなる位置に配置される。
この状態で、位置決め板(2)が下降し、位置決め板(2)の先端の平坦面(2a)が 畳表Aに押しつけられて折りくせがつけられる。
In this state, the folding operation is executed. The operation will be described with reference to FIG. 3 (a).
The floor edge retainer (13) lowers the floor edge retainer (4), presses the end of the tatami floor B against the table (5), and holds the end of the tatami floor B so that it does not float during the folding operation. However, the bent plate (6) is arranged at a position where the top surface is at the same height as the top surface of the table (5).
In this state, the positioning plate (2) is lowered, and the flat surface (2a) at the tip of the positioning plate (2) is pressed against the tatami mat A to make a fold.
この時、折りくせがつけられる位置は、畳床Bの側面が位置決め板(2)に当接した状態で保持された位置で、かつ、位置決め板(2)によってつけられるものであるので、畳床Bの側面に沿う位置となる。
また、位置決め板(2)は、テーブル端面(5a)よりも外側で昇降しており、かつ、
位置決め板(2)の真下にはテーブル(5)はなく、かつ、位置決め板(2)の下降最下点を位置決め板(2)の先端の平坦面(2a)がテーブル(5)の天面よりも下方まで降下する位置と定めているので、畳表Aは、畳表Aの腰の強さと位置決め板昇降エアリンダ(8)空気圧の力で図3(b)に示すように、折り曲げ板(6)とテーブル(5)の間で、屈曲してバランスし、位置決め板(2)の先端が畳表Aを貫通して畳表Aが損傷することがなく、畳表Aは損傷することなく折りくせがつけられる。
At this time, the position where the fold is attached is the position where the side surface of the tatami floor B is held in contact with the positioning plate (2) and is attached by the positioning plate (2). It is located along the side surface of the floor B.
Further, the positioning plate (2) moves up and down outside the table end face (5a), and
There is no table (5) directly under the positioning plate (2), and the flat surface (2a) at the tip of the positioning plate (2) is the top surface of the table (5) at the lowest point of descent of the positioning plate (2). Since it is determined that the position is lowered below, the tatami table A is a bent plate (6) as shown in FIG. It bends and balances between the table (5) and the table (5), the tip of the positioning plate (2) penetrates the tatami table A and the tatami table A is not damaged, and the tatami table A can be folded without being damaged. ..
本発明の縁無畳用畳折り曲げ機(1)では、位置決め板(2)を上下に昇降させて畳表Aに押しつける回数を初期値として10回と定めている。 In the rimless tatami folding machine (1) of the present invention, the number of times the positioning plate (2) is moved up and down and pressed against the tatami table A is set to 10 times as an initial value.
図3(c)に、折りくせがつけられた畳表Aの断面を示す。
畳表Aには溝状の折りくせCが畳床Bの側面に沿って付けられており、位置決め板(2)は先端が平坦な平坦面(2a) であるので、折りくせCが畳表Aの表面(図では下方)まで達することはない。
FIG. 3C shows a cross section of the tatami mat A with a fold.
A groove-shaped fold C is attached to the tatami mat A along the side surface of the tatami floor B, and the positioning plate (2) is a flat surface (2a) having a flat tip. It does not reach the surface (lower in the figure).
続いて、畳作業者により、畳表Aを畳床Bの側面に沿って折り曲げる動作の実行が指示される。
図4(a)と図4(b)に畳表Aが折り曲げられる様子を説明する。
図4(a)の状態で、テーブル昇降エアリンダ(10)により、テーブル(5)と折り曲げ板(6)の高さが調整され、折り曲げ板横押しエアリンダ(9)により、折り曲げ板(6)が畳床Bの方向に移動し、畳表Aが畳床Bの側面に沿って折り曲げられる。
図4(b)の時、折り曲げ板(6)の横方向移動の最大点(図4(b)では右方向)はテーブル端面(5a)よりも内側の位置に定めており、仮に、畳床Bが存在しなければ、折り曲げ板(6)はテーブル端面(5a)にぶつかるようにして、数秒間、畳表Aを畳床Bの側面にエアリンダの空気圧により押さえつけている。
Subsequently, the tatami worker is instructed to perform an operation of bending the tatami table A along the side surface of the tatami floor B.
A state in which the tatami mat A is bent will be described with reference to FIGS. 4 (a) and 4 (b).
In the state of FIG. 4A, the heights of the table (5) and the folding plate (6) are adjusted by the table elevating air linder (10), and the folding plate (6) is adjusted by the folding plate sideways pushing air linder (9). Moving in the direction of the tatami floor B, the tatami table A is bent along the side surface of the tatami floor B.
At the time of FIG. 4 (b), the maximum point of lateral movement of the bent plate (6) (to the right in FIG. 4 (b)) is set at a position inside the table end face (5a), and the tatami floor is tentatively set. If B is not present, the folding plate (6) is made to hit the table end surface (5a), and the tatami mat table A is pressed against the side surface of the tatami floor B by the air pressure of the air linder for several seconds.
曲げ終わったあとの畳表Aと畳床Bの状態を図4(c)に示す。
畳表Aは折りくせCのところから畳床Bの側面に沿って曲げらているので、完成した縁無畳の表面寸法は適切であり、部屋に敷き込んだ場合に隣接する縁無畳の畳表Aがふくろ状になることはない。
FIG. 4 (c) shows the states of the tatami mat table A and the tatami floor B after the bending is completed.
Since the tatami mat A is bent from the fold C along the side surface of the tatami floor B, the surface dimensions of the completed rimless tatami mat are appropriate, and the rimless tatami mat table adjacent to the tatami mat when laid in the room. A does not become a bag.
また、図3(b)の状態において、本発明の縁無畳用畳折り曲げ機(1)ではエアシリンダの空気圧を用い、位置決め板(2)の真下にはテーブル(5)がないようにしている理由は、仮に、位置決め板(2)の真下にテーブル(5)がある場合は、畳表Aは位置決め板(2)とテーブル(5)に挟まれて損傷する場合があるからである。
また、エアシリンダを用いる理由は、位置決め板(2)の駆動にモーターを用いると弾力が得られないので、位置決め板(2)が畳表Aを突き破らない位置で正確に止める必要があり、位置決め板(2)の下降最下限を定める高精度な位置検出センサと高精度の位置決めモーターが必要となり、製造原価が高くなる方法であるので、本発明の縁無畳用畳折り曲げ機(1)ではエアシリンダの空気圧を用いている。
Further, in the state of FIG. 3 (b), in the edgeless tatami folding machine (1) of the present invention, the air pressure of the air cylinder is used so that there is no table (5) directly under the positioning plate (2). The reason for this is that if the table (5) is located directly under the positioning plate (2), the tatami mat table A may be sandwiched between the positioning plate (2) and the table (5) and damaged.
Further, the reason for using an air cylinder is that if a motor is used to drive the positioning plate (2), elasticity cannot be obtained, so it is necessary to accurately stop the positioning plate (2) at a position where it does not break through the tatami mat A, and positioning is performed. Since a high-precision position detection sensor and a high-precision positioning motor that determine the lower limit of descent of the plate (2) are required and the manufacturing cost is high, the rimless folding machine (1) of the present invention is used. The air pressure of the air cylinder is used.
また、本発明の縁無畳用畳折り曲げ機(1)では、位置決め板(2)を上下に昇降させて畳表Aに押しつける回数を初期値を10回と定めているが、作業効率の向上のために、少ない回数に設定する場合もある。
Further, in the edgeless tatami folding machine (1) of the present invention, the initial value of the number of times the positioning plate (2) is moved up and down and pressed against the tatami table A is set to 10 times, but the work efficiency is improved. Therefore, it may be set to a small number of times.
