That is, the supply conveyor 1 supplies the washed and dried cloth to the lower part of the lifting device 2, the lifting device 2 lifts the cloth to a predetermined height, and the temporary holding device 3 receives the lifted cloth and temporarily holds the cloth. It is held and moved to the delivery position to the square end device 4, and the square end device 4 receives an arbitrary part of the cloth suspended from the temporary holding device 3 to expose the corner end of the cloth. The corner edge trimming device 5 holds the corner edge and moves the cloth to the side of the horizontal pulling device 6 while hanging and supporting the cloth, and the horizontal pulling device 6 causes the cloth to lie substantially horizontally in the front-rear direction. The position holding device 7 holds two positions at the same height, one near the corner end of the cloth in the lying state and the other at an intermediate point separated from the corner end by an appropriate distance, and then moves the cloth to the upper side of the edging conveyor 8 and then holds the cloth. The middle part of the cloth is released, and the edging conveyor 8 moves the other part of the cloth held near the corner end by the two-position holding device 7 and moves it to one of the long sides of the cloth. The side edge is exposed, and the upside-down reversing device 9 grips the side edge on the long side of the cloth coming down from the edging conveyor 8 and turns the cloth upside down and holds it hanging down, and the roller 10 The loading moving body 11A of the loading device 11 that moves above the roller 10 in the left-right direction receives the side edge of the cloth on the long side from the upside-down device 9, and the hanging cloth is placed on the roller 10. The roller 10 feeds the cloth on which the cloth is placed so as to hang down on the advancing / retreating device 12 side, leaving the edge on the short side thereof, and the advancing / retreating device 12 advances and remains there from above the roller 10. After receiving the edge on the short side of the cloth, the cloth is retracted while holding the short edge of the cloth, and the cloth is transferred onto the transport conveyor 13 in the unfolded state, and the transport conveyor 13 is the unfolded cloth. The items are carried out and put into the next step, for example, the cloth folding machine D.

各装置の詳細は次のとおりであり、まず、供給コンベア1は、図1〜図3に示すように、モータ1aによって運転中は連続走行していてよく、該供給コンベア1上には洗濯・乾燥後の丸まったままの例えば10〜50枚程度の矩形布類Yからなる塊Xが投下される。供給コンベア1は、布類Yの塊Xを吊上げ装置2の下方(図2に符号X’で示す)まで搬送する。供給コンベア1の搬送方向終端部には、吸引コンベアAが設けられている。吸引コンベアAは、穴開きベルトA1と、穴開きベルトA1を通じて供給コンベア1上の布類Yを吸引する吸引ファンA2と、穴開きベルトA1を回転駆動して吸引した布類Yを吊上げ装置2の真直下(図3に符号X’’で示す)に搬送するモータA3とからなる。穴開きベルトA1の終端部近傍には塊Xが供給コンベア1から落下するのを防止する壁1bが立設されている。また、供給コンベア1の搬送方向終端部には、吸引コンベアAに加えてまたはこれに代えて、供給コンベア1上の布類を吊上げ装置2の真直下へ向けて押し込む押し出し装置Bが設けられていてよい。押し出し装置Bは、シリンダB1と、該シリンダB1によって進退させられる押し出し棒B2とからなる。 The details of each device are as follows. First, as shown in FIGS. 1 to 3, the supply conveyor 1 may be continuously running during operation by the motor 1a, and the supply conveyor 1 may be washed. A lump X made of, for example, about 10 to 50 pieces of rectangular cloth Y, which remains curled after drying, is dropped. The supply conveyor 1 conveys the mass X of the cloth Y to the lower part of the lifting device 2 (indicated by reference numeral X'in FIG. 2). A suction conveyor A is provided at the end of the supply conveyor 1 in the transport direction. The suction conveyor A lifts the perforated belt A1, the suction fan A2 that sucks the cloth Y on the supply conveyor 1 through the perforated belt A1, and the cloth Y that is sucked by rotating the perforated belt A1. It is composed of a motor A3 that conveys directly below (indicated by reference numeral X ″ in FIG. 3). A wall 1b is erected near the end of the perforated belt A1 to prevent the lump X from falling from the supply conveyor 1. Further, at the end of the supply conveyor 1 in the transport direction, in addition to or in place of the suction conveyor A, an extrusion device B for pushing the cloth on the supply conveyor 1 directly below the lifting device 2 is provided. It's okay. The extrusion device B includes a cylinder B1 and an extrusion rod B2 that is moved forward and backward by the cylinder B1.

In the illustrated example, the lifting device includes a drive belt 23 and a motor 22. The elevating device may have any structure as long as the chuck 21 can be elevated and lowered between a predetermined height and the transport surface of the supply conveyor 1, and may be, for example, a chain type or a slider unit that travels up and down on rails. good. When the lifting device 2 moves the chuck 21 to the lowest position (the position shown by the virtual line and the reference numeral 21'in FIG. 4) by the drive belt 23 and the motor 22, the chuck 21 moves the chuck 21 to the terminal portion of the supply conveyor 1. The chuck 21 is adapted to hold the contact portion of the cloth Y in contact with the cloth Y located at. The cloth holding portion by the chuck 21 may be any place. Further, when the chuck 21 is raised, the chuck 21 moves up to a predetermined height (top position) shown by the solid line in FIG. 4 while holding the cloth Y by the chuck 21, and the cloth Y is suspended. It is designed to hold. At this time, two or more pieces of cloth Y may be held by the chuck 21 and lifted.

仮保持装置3は、図1および図4に示すように、チャック31と該チャック31を前後方向に進退させる進退装置(伸縮シリンダ32)とを有している。仮保持装置3は、吊上げ装置2のチャック21が最上位置に移動したとき、あるいはチャック21が最上位置で保持している布類Yを図示しないセンサで検出したときに、伸縮シリンダ32が伸長し、チャック31が図4に仮想線で図示する位置(符号31’で示す)まで前進し、吊上げ装置2で吊上げられた布類Yの上端部付近を仮保持装置3のチャック31で受取り(このとき吊上げ装置2のチャック21は布類Yを解放する)、その後、伸縮シリンダ32が短縮して、図4に実線で図示するようにチャック31で布類Yを吊下げたまま所定位置まで後退するようになっている。なお、チャック31で吊下げられている布類Yの最下端(図4の符号Yaで示す)にはほとんどの場合、布類の角端のうちの1つが出現する。 As shown in FIGS. 1 and 4, the temporary holding device 3 has a chuck 31 and an advancing / retreating device (expandable cylinder 32) for advancing / retreating the chuck 31 in the front-rear direction. In the temporary holding device 3, the telescopic cylinder 32 extends when the chuck 21 of the lifting device 2 moves to the uppermost position, or when the cloth Y held by the chuck 21 at the uppermost position is detected by a sensor (not shown). , The chuck 31 advances to the position shown by the virtual line in FIG. 4 (indicated by reference numeral 31'), and the vicinity of the upper end portion of the cloth Y lifted by the lifting device 2 is received by the chuck 31 of the temporary holding device 3 (this). When the chuck 21 of the lifting device 2 releases the cloth Y), the telescopic cylinder 32 is shortened, and the cloth Y is retracted to a predetermined position while being suspended by the chuck 31 as shown by the solid line in FIG. It is designed to do. In most cases, one of the corner ends of the cloth appears at the lowermost end of the cloth Y suspended by the chuck 31 (indicated by the reference numeral Ya in FIG. 4).

角端出し装置4は、図5〜図9に示すように、仮保持装置3のチャック31によりその後退位置にて吊下げ保持されている布類Yを受取るチャック41と、該チャック41を前後に進退させる進退装置(伸縮シリンダ42)と、上面に布類Yが載せられる台板43と、台板43上を引き摺られる布類Yの終端部(角端Ya)を検出する例えば光電管からなるセンサ49と、台板43上の布類Yの中央部を台板43との間に挟みこむ押え板47と、該押え板47を上下動させる伸縮シリンダ48と、一対の角端出しローラ44,45と、一方の角端出しローラ45を他方の角端出しローラ44に対して近接・離間させる伸縮シリンダ46と、を有している。 As shown in FIGS. 5 to 9, the square end device 4 has a chuck 41 that receives the cloth Y suspended and held at its retracted position by the chuck 31 of the temporary holding device 3, and the chuck 41 is moved back and forth. It consists of an advancing / retreating device (expandable cylinder 42) for advancing and retreating, a base plate 43 on which the cloth Y is placed on the upper surface, and a photoelectric tube for detecting the end portion (corner end Ya) of the cloth Y dragged on the base plate 43. A presser plate 47 that sandwiches the central portion of the cloth Y on the base plate 43 between the sensor 49 and the base plate 43, a telescopic cylinder 48 that moves the presser plate 47 up and down, and a pair of square end rollers 44. , 45, and a telescopic cylinder 46 that causes one square end roller 45 to approach and separate from the other square end roller 44.

そして、この角端出し装置4は、図5に示すように仮保持装置3のチャック31が布類Yを保持した状態で後退位置まで作動したときに、伸縮シリンダ42が伸長してチャック41が前進し、該チャック41が仮保持装置3のチャック31から布類Yを受け取り、続いて、図6に示すように、伸縮シリンダ42が短縮してチャック41が布類Yを保持したまま布類Yを台板43上で所定距離引き込み、その後チャック41が布類Yを放し、次いで、図7に示すように、奥側に位置する角端出しローラ45が符号45’の位置から下降し、手前側の角端出しローラ44との間に布類Yの先端部を挟み込み、また、押え板47が符号47’で示す上昇位置から下降して台板43との間に布類Yの中央部を挟み込み、この状態で、図8に示すように、両角端出しローラ44,45が矢印方向に回転することで布類Yは垂れ下がった状態となり、台板43上を引き摺られる布類Yの終端部(角端Yaとなる)がセンサ49,49で検出されると(あるいは布類Yがセンサ49,49で検出されなくなると)、両角端出しローラ44,45の回転速度が低速に切り替えられるようになっている。この一連の動きの中で、布類Yが複数枚であった場合には、台板43と押え板47とで終端部を挟持された1枚の布類Yを除いて他の布類Zは落下する。その後、布類Yの終端部(角端Ya)を両角出しローラ44,45間に配置された例えば光電管からなる別のセンサ4a,4aが検出すると(あるいは布類Yがセンサ4a,4aで検出されなくなると)、角端出しローラ44,45の回転が停止し、布類Yの角端Yaまたはその付近が角端出しローラ44,45に挟まれて保持された状態となり、角端出し作業が完了する。 Then, as shown in FIG. 5, when the chuck 31 of the temporary holding device 3 operates to the retracted position while holding the cloth Y, the telescopic cylinder 42 extends and the chuck 41 moves. Moving forward, the chuck 41 receives the cloth Y from the chuck 31 of the temporary holding device 3, and subsequently, as shown in FIG. 6, the telescopic cylinder 42 is shortened and the chuck 41 holds the cloth Y. Y is pulled in on the base plate 43 by a predetermined distance, after which the chuck 41 releases the cloth Y, and then, as shown in FIG. 7, the square end roller 45 located on the back side descends from the position of reference numeral 45'. The tip of the cloth Y is sandwiched between the square end roller 44 on the front side, and the pressing plate 47 descends from the ascending position indicated by the reference numeral 47'and is located at the center of the cloth Y between the base plate 43 and the base plate 43. In this state, as shown in FIG. 8, the cloth Y is in a hanging state due to the rotation of the double-sided end-out rollers 44 and 45 in the direction of the arrow, and the cloth Y is dragged on the base plate 43. When the end portion (which becomes the square end Ya) is detected by the sensors 49, 49 (or when the cloth Y is no longer detected by the sensors 49, 49), the rotation speed of the double-sided end-out rollers 44, 45 is switched to a low speed. It is designed to be used. In this series of movements, when there are a plurality of cloths Y, the other cloths Z except one cloth Y whose end portion is sandwiched between the base plate 43 and the holding plate 47. Will fall. After that, when the end portion (corner end Ya) of the cloth Y is detected by another sensor 4a, 4a composed of, for example, a phototube arranged between the double-sided roller 44, 45 (or the cloth Y is detected by the sensors 4a, 4a). (When this is not done), the rotation of the square end rollers 44 and 45 is stopped, and the corner end Ya of the cloth Y or its vicinity is sandwiched between the square end rollers 44 and 45 and held. Is completed.

なお、図示例では、吊上げ装置2で吊上げた布類Yを一旦仮保持装置3で仮保持した後、角端出し装置4のチャック41で持替えるようにしているが、図示しない他の実施例では、仮保持装置3を省略し、吊上げ装置2で吊上げている布類Yを直に角端出し装置4のチャック41で保持することもできる。 In the illustrated example, the cloth Y lifted by the lifting device 2 is temporarily held by the temporary holding device 3 and then replaced by the chuck 41 of the square end device 4, but other embodiments (not shown) are shown. Then, the temporary holding device 3 may be omitted, and the cloth Y lifted by the lifting device 2 may be directly held by the chuck 41 of the square end device 4.

角端取り装置5は、図10に示すように、角端出しローラ44,45の下方に配置されたチャック51と該チャック51を角端出しローラ44,45の接触部の真下の範囲で左右方向(図1参照)に進退させる進退装置(伸縮シリンダ52)とを有している。角端取り装置5は、角端出し装置4の一対の角端出しローラ44,45で布類Yの角端Yaまたはその付近が保持されているときに、伸縮シリンダ52が伸長してチャック51が図10中仮想線で示すように左方向に前進し、該チャック51で布類Yの角端Yaの少し下を保持し、布類Yを垂れ下げたまま右側(横引き装置6側)に後退するように作動する。また、チャック51には布類Yを検出するセンサ53が装着されており、このセンサ53によりチャック51が布類Yに近づいたことを検出してチャック51を動作させることで、布類Yを確実に保持させることができる。 As shown in FIG. 10, the square edge trimming device 5 left and right the chuck 51 arranged below the square edge roller 44, 45 and the chuck 51 in the range directly below the contact portion of the square edge roller 44, 45. It has an advancing / retreating device (expandable cylinder 52) for advancing / retreating in a direction (see FIG. 1). In the corner edge trimming device 5, the telescopic cylinder 52 extends and the chuck 51 extends when the corner edge Ya or the vicinity thereof of the cloth Y is held by the pair of square edge trimming rollers 44 and 45 of the square edge trimming device 4. Moves forward to the left as shown by a virtual line in FIG. 10, holds a little below the corner end Ya of the cloth Y with the chuck 51, and holds the cloth Y hanging down on the right side (horizontal pulling device 6 side). Operates to retreat to. Further, the chuck 51 is equipped with a sensor 53 for detecting the cloth Y, and the sensor 53 detects that the chuck 51 has approached the cloth Y and operates the chuck 51 to move the cloth Y. It can be reliably held.

角端取り装置5の伸縮シリンダ52が短縮した状態でのチャック51の下方後側直近位置には、台板64が設けられている(図11参照)。この台板64は、次に説明する横引き装置6で布類上端部(角端Ya)付近を受取って後側に移動させたときに、該布類Yの終端側を支持するためのものである。 A base plate 64 is provided at a position closest to the lower rear side of the chuck 51 in a state where the telescopic cylinder 52 of the square end trimming device 5 is shortened (see FIG. 11). The base plate 64 is for supporting the end side of the cloth Y when the horizontal pulling device 6 described below receives the vicinity of the upper end portion (corner end Ya) of the cloth and moves it to the rear side. Is.

なお、この実施例では、矩形布類Yの1つの角端Yaを現出させるのに、上記吊上げ装置2、仮保持装置3および角端出し装置4を用いて、丸まった状態の矩形布類Yから自動で角端出しを行えるようにしているが、この布類角端出し作業は、例えば丸まった状態の布類Yから作業員が手作業で1つの角端を捜し出すようにしてもよい。その場合は、捜し出した布類角端Yaを作業員の手で角端取り装置5のチャック51に受け取らせたり、直接後述の横引き装置6のチャック61に受け取らせたりするとよい。 In this embodiment, in order to reveal one square end Ya of the rectangular cloth Y, the lifting device 2, the temporary holding device 3, and the square end device 4 are used to make the rectangular cloth in a curled state. Although the corner edge can be automatically extracted from Y, in this cloth corner edge extraction work, for example, the worker may manually search for one corner edge from the rolled cloth Y. .. In that case, the found cloth square end Ya may be picked up by the chuck 51 of the square end trimming device 5 by the worker's hand, or may be directly picked up by the chuck 61 of the horizontal pulling device 6 described later.

横引き装置6は、図11〜図14に示すように、チャック61と該チャック61を前後方向に進退させる進退装置とを有している。図示例では、進退装置は、チャック61を保持する駆動ベルト63と、駆動ベルト63を巻き掛けたプーリを回転させてチャック61を前後方向に進退させるモータ62とからなるが、進退装置はいかなる構造のものでもよく、例えば伸縮シリンダを用いることもできる。横引き装置6は、図11に示すように、角端取り装置5のチャック51が布類Yを保持して後退したときに、チャック61が仮想線および符号61’で図示する位置に前進し、該前進位置のチャック61’で布類上端部(角端Ya)の少し下の位置を保持する。続いて、角端取り装置5のチャック51が布類Yを解放した後、図12に示すように、チャック61で布類角端Ya付近を保持した状態で、チャック61を後方に移動させ、台板64上で布類Yを横引きする。次いで、図13に示すように、所定距離横引き後に上押え板65がシリンダ66によって符号65’で示す上昇位置から下降して台板64との間に布類Yを挟み込み、その後も横引きは継続され、台板64の下方に配置されたセンサ67が布類Yの終端部Ybを検出したとき(またはセンサ67が布類Yを検出しなくなったとき)、横引き速度が低速に切り替えられる。そして、図14に示すように、台板64の近傍に配置された別のセンサ68が布類Yの終端部Ybを検出したとき(またはセンサ68が布類Yを検出したくなったとき)、横引きは停止される。このとき、布類Yはチャック61で保持された角端Yaおよび上押え板65で押えられた角端Yb以外の残りの2つの角端が前後に並び、垂れ下がった部分に長辺側の側縁の一方Ycが出現した状態(三角形状)となる。 As shown in FIGS. 11 to 14, the lateral pulling device 6 has a chuck 61 and an advancing / retreating device for advancing / retreating the chuck 61 in the front-rear direction. In the illustrated example, the advancing / retreating device includes a drive belt 63 for holding the chuck 61 and a motor 62 for rotating the pulley around which the drive belt 63 is wound to advance / retreat the chuck 61 in the front-rear direction. For example, a telescopic cylinder may be used. As shown in FIG. 11, when the chuck 51 of the corner trimming device 5 holds the cloth Y and retracts, the lateral pulling device 6 advances the chuck 61 to the position shown by the virtual line and the reference numeral 61'. The chuck 61'in the forward position holds a position slightly below the upper end (corner end Ya) of the cloth. Subsequently, after the chuck 51 of the corner edge trimming device 5 releases the cloth Y, as shown in FIG. 12, the chuck 61 is moved rearward while holding the vicinity of the cloth corner end Ya by the chuck 61. Cloth Y is pulled sideways on the base plate 64. Next, as shown in FIG. 13, the upper presser plate 65 descends from the ascending position indicated by the reference numeral 65'by the cylinder 66 after laterally pulling a predetermined distance, sandwiches the cloth Y with the base plate 64, and then laterally pulls. Is continued, and when the sensor 67 arranged below the base plate 64 detects the end portion Yb of the cloth Y (or when the sensor 67 no longer detects the cloth Y), the lateral pulling speed is switched to a low speed. Be done. Then, as shown in FIG. 14, when another sensor 68 arranged in the vicinity of the base plate 64 detects the terminal portion Yb of the cloth Y (or when the sensor 68 wants to detect the cloth Y). , Horizontal pulling is stopped. At this time, in the cloth Y, the remaining two corner ends other than the corner end Ya held by the chuck 61 and the corner end Yb pressed by the upper presser plate 65 are lined up in the front-rear direction, and the side on the long side is on the hanging portion. One of the edges, Yc, appears (triangular).

図15に示すように、台板64および上押え板65の右側方には、モータ81によって駆動される縁出しコンベア8が設置されている。この縁出しコンベア8は、左右方向に延在する複数(図示例では9本)の細ベルト8aを前後方向に互いに間隔をあけて配置したものである。 As shown in FIG. 15, an edging conveyor 8 driven by a motor 81 is installed on the right side of the base plate 64 and the upper pressing plate 65. The edging conveyor 8 is formed by arranging a plurality of (nine in the illustrated example) thin belts 8a extending in the left-right direction at intervals in the front-rear direction.

2位置保持装置7は、図15〜図20に示すように、前後方向に延びる連結棒70の後端および前端にそれぞれ取り付けられた2つのチャック71,72(以下、中間部保持チャック71、角端保持チャック72ともいう。)と、該各チャック71,72を昇降させる昇降シリンダ73と、各チャック71,72を昇降シリンダ73ごと左右に進退させる進退装置とを有している。進退装置は、昇降シリンダ73を垂下状態で保持する駆動ベルト75と、駆動ベルト75に巻き掛けたプーリを回転させるモータ74とからなるが、チャック71,72を左右方向に移動させることができればどのような構造のものでもよく、進退シリンダを用いてもよい。チャック71,72間の距離は、例えば、長さ調整可能な連結棒70を用いるか、連結棒70へのチャック71,72の取付け位置が可変な構造とすることで、処理する布類Yの大きさ等に応じて適宜変更可能としてもよい。 As shown in FIGS. 15 to 20, the two-position holding device 7 has two chucks 71 and 72 (hereinafter, intermediate portion holding chuck 71, corners) attached to the rear end and the front end of the connecting rod 70 extending in the front-rear direction, respectively. It also has an end holding chuck 72), an elevating cylinder 73 for elevating and lowering each of the chucks 71 and 72, and an advancing / retreating device for advancing and retreating each chuck 71 and 72 together with the elevating cylinder 73. The advancing / retreating device consists of a drive belt 75 that holds the elevating cylinder 73 in a hanging state and a motor 74 that rotates a pulley wound around the drive belt 75. Such a structure may be used, or an advancing / retreating cylinder may be used. The distance between the chucks 71 and 72 can be determined by, for example, using a connecting rod 70 whose length can be adjusted, or by adopting a structure in which the mounting positions of the chucks 71 and 72 on the connecting rod 70 are variable. It may be changed as appropriate according to the size and the like.

図15に示すように、角端保持チャック72は横引き装置6で横たわらせた布類Yの前側端部(角端)Ybを保持し得る位置にあり、中間部保持チャック71は該横たわらせた布類Yの後方側中間部の適所を保持し得る位置にある。 As shown in FIG. 15, the square end holding chuck 72 is in a position where the front end portion (corner end) Yb of the cloth Y laid down by the horizontal pulling device 6 can be held, and the intermediate portion holding chuck 71 is in the intermediate portion holding chuck 71. It is in a position where it can hold an appropriate position in the middle part on the rear side of the laid cloth Y.

昇降シリンダ73は、その短縮状態では各チャック71,72を横たわらせた布類Yの上方位置で待機させ(図15の実線で図示する状態)、伸長状態では各チャック71,72が図15に仮想線で図示するように横たわらせた布類Yの上縁を保持し得る位置まで降下するようになっている。 The elevating cylinder 73 stands by at a position above the cloth Y on which the chucks 71 and 72 are laid in the shortened state (the state shown by the solid line in FIG. 15), and the chucks 71 and 72 are shown in the extended state. It descends to a position where it can hold the upper edge of the cloth Y laid down on 15 as illustrated by a virtual line.

昇降シリンダ73の伸長により2位置保持装置7が下降すると、図16に示すように、角端保持チャック72が布類Yの前側端部(角端)Ybを保持するとともに、中間部保持チャック71が布類Yの後方側の中間部を保持する。この際、図15に示すように、上押え板65の後方近傍に設けられたチャック69の開度を符号69’で示す大きく開いた状態から狭めることで、角端保持チャック72が布類Yを保持し易くすることができる。その後、布類Yは、横引き装置6のチャック61、上押え板65およびチャック69による保持または拘束から解放される。2位置保持装置7は次いで、図17に示すように、縁出しコンベア8の上方位置で進退装置によって縁出しコンベア8の終端側へ向けて移動する。縁出しコンベア8のベルトは図17中の矢印の方向に移動しており、布類Yの三角形状部(Yc近傍)がコンベア8に接触し得る。また、コンベア8の上下ベルト間に設置されたブロー装置82のエアブローの作用により、当該三角形状部がコンベア8の流れ方向に靡いた(沿った)状態となる。 When the two-position holding device 7 is lowered due to the extension of the elevating cylinder 73, the square end holding chuck 72 holds the front end (corner end) Yb of the cloth Y and the intermediate holding chuck 71 as shown in FIG. Holds the middle part on the rear side of the cloth Y. At this time, as shown in FIG. 15, by narrowing the opening degree of the chuck 69 provided near the rear of the upper presser plate 65 from the wide open state indicated by reference numeral 69', the square end holding chuck 72 is made of cloth Y. Can be easily held. After that, the cloth Y is released from being held or restrained by the chuck 61, the upper pressing plate 65, and the chuck 69 of the lateral pulling device 6. The two-position holding device 7 then moves toward the end side of the edging conveyor 8 by the advancing / retreating device at a position above the edging conveyor 8 as shown in FIG. The belt of the edging conveyor 8 is moving in the direction of the arrow in FIG. 17, and the triangular portion (near Yc) of the cloth Y can come into contact with the conveyor 8. Further, due to the action of the air blow of the blow device 82 installed between the upper and lower belts of the conveyor 8, the triangular portion is in a state of being laid (along) in the flow direction of the conveyor 8.

続いて、図18に示すように、2位置保持装置7の後方のチャック71が布類Yを解放し、布類Yの片側(角端Ybよりも後方側の部分)が縁出しコンベア8の移動するベルト上に落下する。布類Yの前側端部(角端Yb)は角端保持チャック72で保持されたままであるので、布類Yの落下部分のみが図19に示すように右側へ移動していく。布類Yの落下部分が所定距離移動すると、布類Yの長辺側の一方の側縁Ycが縁出しコンベア8の流れ方向に対して略直交する配置関係となる。この配置関係となったところで、図20に示すように、もう一方のチャック72が布類Yを放し、布類Yを完全に縁出しコンベア8上に落下させる。縁出しコンベア8の終端部付近には、縁出しコンベア8上を移送されてくる布類Yの先行側の側縁Ycを検出する2つのセンサ83が設置されており、このセンサ83が布類Yを検知すると縁出しコンベア8は低速に切り替えられる。 Subsequently, as shown in FIG. 18, the chuck 71 behind the two-position holding device 7 releases the cloth Y, and one side of the cloth Y (the portion rearward of the square end Yb) of the edging conveyor 8 It falls on a moving belt. Since the front end portion (corner end Yb) of the cloth Y is still held by the square end holding chuck 72, only the falling portion of the cloth Y moves to the right side as shown in FIG. When the falling portion of the cloth Y moves by a predetermined distance, one side edge Yc on the long side side of the cloth Y is arranged so as to be substantially orthogonal to the flow direction of the edging conveyor 8. At this arrangement, as shown in FIG. 20, the other chuck 72 releases the cloth Y, and the cloth Y is completely dropped onto the edging conveyor 8. Near the end of the edging conveyor 8, two sensors 83 for detecting the side edge Yc on the preceding side of the cloth Y transferred on the edging conveyor 8 are installed, and these sensors 83 are used for cloth. When Y is detected, the edging conveyor 8 is switched to a low speed.

上下反転装置9は、図21に示すように、縁出しコンベア8の終端部近傍に配置され、布類Yの長辺側の一方の側縁Ycを把持する2つのチャック92,93と、各チャック92,93の近傍に設けられた2つのセンサ94,95と、チャック92,93を支持する反転軸96と、反転軸96を回動させる回動シリンダ91とを有している。なお、2つのチャック92,93で把持した布類Yを反転させることができればどのような機構を用いてもよく、回動シリンダ91に代えて、反転軸96を正逆回転させるモータを用いてもよい。2つのチャック92,93は、センサ94,95による布類Yの側縁Ycの検知信号に基づき、互いに独立して動作するよう構成されており、これにより布類Yの側縁Ycを2つのチャック92,93間で真直ぐ保持することができる。 As shown in FIG. 21, the upside-down device 9 is arranged near the end of the edging conveyor 8, and has two chucks 92 and 93 that grip one side edge Yc on the long side side of the cloth Y, and each of them. It has two sensors 94 and 95 provided in the vicinity of the chucks 92 and 93, a reversing shaft 96 for supporting the chucks 92 and 93, and a rotating cylinder 91 for rotating the reversing shaft 96. Any mechanism may be used as long as the cloth Y gripped by the two chucks 92 and 93 can be reversed, and instead of the rotating cylinder 91, a motor that rotates the reversing shaft 96 in the forward and reverse directions is used. May be good. The two chucks 92 and 93 are configured to operate independently of each other based on the detection signal of the side edge Yc of the cloth Y by the sensors 94 and 95, whereby the two side edges Yc of the cloth Y are formed. It can be held straight between the chucks 92 and 93.

この上下反転装置9は、次のように作動する。まず、縁出しコンベア8上を移送されてくる布類の先行側の側縁Ycがセンサ94,95で検知されるまでは、各チャック92,93が、図20に示すように、略横向き(やや上方傾斜)姿勢で待機しており、縁出しコンベア8上を移送される布類Yの先行側の側縁Ycがセンサ94,95で検知されると、該センサ94,95からの検知信号に基づき各チャック92,93が布類の先行側の側縁Ycを保持する。そして、その直後に回動シリンダ91が短縮し、各チャック92,93が布類の側縁Ycを保持したまま下方に高速で回動して、図22に示す下向き姿勢になる。このとき、各チャック92,93で保持されていた布類Yは、急速に下方に振り降ろされて(布類の短辺方向に捌き作用が発生し)垂れ下げられる。そして、下向き姿勢で布類の側縁Ycを保持している各チャック92,93は、その側縁Ycの各保持部を、後述する載せ掛け装置11の各チャック111,112に受け渡した時点で解放し、その直後に上方に回動して元の待機位置まで戻される。 The upside-down device 9 operates as follows. First, until the leading side edge Yc of the cloth transferred on the edging conveyor 8 is detected by the sensors 94 and 95, the chucks 92 and 93 are oriented substantially sideways (as shown in FIG. 20). When the side edge Yc on the leading side of the cloth Y transferred on the edging conveyor 8 is detected by the sensors 94 and 95, the detection signal from the sensors 94 and 95 is detected. Each chuck 92, 93 holds the side edge Yc on the leading side of the cloth based on the above. Immediately after that, the rotating cylinder 91 shortens, and the chucks 92 and 93 rotate downward at high speed while holding the side edges Yc of the cloth, and take the downward posture shown in FIG. At this time, the cloth Y held by the chucks 92 and 93 is rapidly swung down (a handling action is generated in the short side direction of the cloth) and is hung down. Then, when the chucks 92 and 93 holding the side edge Yc of the cloth in the downward posture deliver each holding portion of the side edge Yc to the chucks 111 and 112 of the mounting device 11 described later. It is released, and immediately after that, it rotates upward and is returned to the original standby position.

図23に示すように、縁出しコンベア8の前方側部分の直下には、ローラ10と、該ローラ10上に布類Yを載せ掛けるための、載せ掛け装置11の載せ掛け移動体11Aとが、該載せ掛け移動体11Aが上でローラ10が下になる位置関係で設置されている。 As shown in FIG. 23, directly below the front side portion of the edging conveyor 8, a roller 10 and a loading moving body 11A of the loading device 11 for mounting the cloth Y on the roller 10 are provided. The loading moving body 11A is installed in a positional relationship in which the roller 10 is on the top and the roller 10 is on the bottom.

載せ掛け移動体11Aは、上下反転装置9側に向けられた進退台110と、進退台110の両側方に配置され、上下反転装置9のチャック92,93から布類Yを受け取る2つのチャック111,112と、チャックセンサ113,114とを有している。載せ掛け移動体11Aは、進退装置によって左右方向(ローラ10の回転軸線方向)に進退移動される。進退装置は、図示例では、載せ掛け移動体11Aを保持する駆動ベルト116と駆動ベルト116を巻き掛けたプーリを回転させるモータ115とからなるが、チャック111,112を左右方向に進退させることができれば如何なる構造のものでもよく、例えば進退シリンダを用いてもよい。 The loading moving body 11A is arranged on both sides of the advancing / retreating table 110 facing the upside down device 9 side and the advancing / retreating table 110, and two chucks 111 that receive the cloth Y from the chucks 92 and 93 of the upside down device 9. , 112 and chuck sensors 113, 114. The loading moving body 11A is moved back and forth in the left-right direction (direction of the rotation axis of the roller 10) by the advancing / retreating device. In the illustrated example, the advancing / retreating device includes a drive belt 116 for holding the mounted moving body 11A and a motor 115 for rotating a pulley around which the drive belt 116 is wound. If possible, any structure may be used, for example, an advancing / retreating cylinder may be used.

載せ掛け移動体11Aは、図23に示す待機位置から、上下反転装置9で保持された布類Yへ接近するよう、ローラ10の軸線方向一端(図23では右側の端)を超える所定の進出位置まで移動し、図24に示すように、チャックセンサ113,114が布類Yを検出するとチャック111,112が進退台110の両側部へ向けて閉鎖されて布類Yが保持される。ここでチャック111,112による布類Yの保持位置は、上下反転装置9のチャック92,93による布類Yの保持位置に近い位置である。なお、2つのチャック111,112は別個独立に動作するよう構成してもよく、このようにすれば、布類Yの側縁Ycの、2つのチャック111,112間の部分をより真直ぐに保持することができる。布類Yの受け渡し後、上下反転装置9は、図25に示すように元の位置に反転して戻り、載せ掛け移動体11Aの軌道上から退避する。ローラ10は、その回転軸線が載せ掛け移動体11Aの進退方向と平行となるよう配置されているので、布類Yを垂下保持する載せ掛け移動体11Aが後退すると、図25に示すように、布類Yがローラ10上に載せ掛けられてローラ10上から垂れ下がった状態になる。その際、チャック111,112で保持された長辺側の側縁Ycとは反対側の側縁Ydはセンサ101で検知され、当該検知の後の所定時間経過後にチャック111,112が布類Yを解放する。当該所定時間は、布類Yの幅方向中央がローラ10の幅方向中央と略一致したときにチャック111,112が布類Yを解放するよう適宜設定される。なお、載せ掛け移動体11Aはチャック111,112が布類Yを解放した後も所定距離だけ後退し続ける。 The loading moving body 11A advances from the standby position shown in FIG. 23 beyond the axial end end (the right end in FIG. 23) of the roller 10 so as to approach the cloth Y held by the upside down device 9. After moving to the position and as shown in FIG. 24, when the chuck sensors 113 and 114 detect the cloth Y, the chucks 111 and 112 are closed toward both sides of the advancing / retreating table 110 to hold the cloth Y. Here, the holding position of the cloth Y by the chucks 111 and 112 is a position close to the holding position of the cloth Y by the chucks 92 and 93 of the vertical inversion device 9. The two chucks 111 and 112 may be configured to operate independently, and in this way, the portion of the side edge Yc of the cloth Y between the two chucks 111 and 112 may be held more straight. can do. After the cloth Y is delivered, the upside-down inversion device 9 reverses and returns to the original position as shown in FIG. 25, and retracts from the orbit of the mounted moving body 11A. Since the rotation axis of the roller 10 is arranged to be parallel to the advancing / retreating direction of the loading moving body 11A, when the loading moving body 11A that holds the cloth Y hanging down retracts, as shown in FIG. 25, the roller 10 is arranged. The cloth Y is placed on the roller 10 and hangs down from the roller 10. At that time, the side edge Yd on the side opposite to the side edge Yc on the long side held by the chucks 111 and 112 is detected by the sensor 101, and the chucks 111 and 112 are placed on the cloth Y after a predetermined time has elapsed after the detection. Release. The predetermined time is appropriately set so that the chucks 111 and 112 release the cloth Y when the center in the width direction of the cloth Y substantially coincides with the center in the width direction of the roller 10. The mounted moving body 11A continues to retreat by a predetermined distance even after the chucks 111 and 112 release the cloth Y.

この際、布類Yの、載せ掛け移動体11Aによって把持された側縁Ycとは反対側の側縁Ydに皺や折れ返りが発生する場合がある(図38参照)。そこで、本実施形態の載せ掛け装置11には、図26および図27に示すように、ローラ10の軸線方向一端の角部10aに対して進退可能に設けられ、その進出位置にて、載せ掛け移動体11Aによって該角部10aを通過する布類Yの、ローラ10を向く面とは反対側の面(上面)に摺接し、載せ掛け移動体11Aによる布類Yの後退移動と協働して布類の皺および/または折れ返りを矯正する摺接体として、ブラシ体11Bが設けられている。なお、摺接体は、布類Yの皺や折れ返りを直すことができればブラシ体11Bに限らず、例えば樹脂板、金属板、樹脂棒、金属棒等の固形体であってもよい。なお、摺接体としてブラシ体11B以外の固形体を用いる場合には、少なくとも、布類Yとの接触部分を曲面状または球面状とすることが好ましく、このようにすれば、固形体を布類Yに滑らかに接触させ得て、接触(摺接)による布類Yの傷損を防止することができる。 At this time, wrinkles or folds may occur on the side edge Yd of the cloth Y opposite to the side edge Yc gripped by the mounted moving body 11A (see FIG. 38). Therefore, as shown in FIGS. 26 and 27, the mounting device 11 of the present embodiment is provided so as to be able to advance and retreat with respect to the corner portion 10a at one end in the axial direction of the roller 10, and is mounted at the advancing position. The moving body 11A slides on the surface (upper surface) of the cloth Y passing through the corner portion 10a on the side opposite to the surface facing the roller 10, and cooperates with the backward movement of the cloth Y by the mounted moving body 11A. The brush body 11B is provided as a sliding contact body for correcting wrinkles and / or bending of the cloth. The sliding contact body is not limited to the brush body 11B as long as the wrinkles and folds of the cloth Y can be corrected, and may be a solid body such as a resin plate, a metal plate, a resin rod, or a metal rod. When a solid body other than the brush body 11B is used as the sliding contact body, it is preferable that at least the contact portion with the cloth Y is curved or spherical, and in this way, the solid body is clothed. The cloth Y can be smoothly contacted with the cloth Y, and the cloth Y can be prevented from being damaged by the contact (sliding contact).

ブラシ体11Bは、先端に複数本のブラシ毛117を有するとともに、その下端部が進退機構118の揺動軸118aに固定され、該揺動軸118aの正逆回転に伴って図26に実線で示す起立姿勢の後退位置(待機状態)と、同図中に仮想線で示す傾斜姿勢の進出位置(稼動状態)との間で揺動するよう構成されている。ブラシ毛117は、布類Yに押し当てられた際に変形して布類Yを傷つけることがない一方で、布類Yを伸ばして皺や折れ返りを直すことができる程度の硬さを有するものであり、ブラシ毛117の材質は特に限定されず、例えばナイロンやポリプロピレン等の化学繊維や馬毛等の動物繊維、タンピコ繊維等の植物繊維を用いることができる。 The brush body 11B has a plurality of brush bristles 117 at its tip, and its lower end is fixed to the swing shaft 118a of the advancing / retreating mechanism 118, and is shown by a solid line in FIG. 26 as the swing shaft 118a rotates in the forward and reverse directions. It is configured to swing between the retracted position (standby state) of the standing posture shown and the advanced position (operating state) of the tilted posture shown by the virtual line in the figure. The brush bristles 117 are not deformed when pressed against the cloth Y and do not damage the cloth Y, but have a hardness sufficient to stretch the cloth Y to correct wrinkles and folds. The material of the brush bristles 117 is not particularly limited, and for example, chemical fibers such as nylon and polypropylene, animal fibers such as horsehair, and plant fibers such as tampico fibers can be used.

進退機構118は、図示例では、揺動軸118aと、下端が枢軸によって揺動可能に支持されたシリンダ118bと、該シリンダ118bのロッド進退を揺動軸118aの回転に変換するリンク118cとで構成されるが、これに限らず、正逆回転可能なモータによって揺動軸118aを正逆回転させることで、ブラシ毛117をローラ10の角部10aに近接、離間させるようにしてもよく、あるいは、シリンダのロッド先端に摺接体を装着し、このロッドを進退させることでローラ10の角部10aに対して摺接体を直線的に近接、離間させるような揺動を伴わない進退機構(図示省略)を採用してもよい。 In the illustrated example, the advancing / retreating mechanism 118 is composed of a swinging shaft 118a, a cylinder 118b whose lower end is swingably supported by a pivot shaft, and a link 118c that converts the rod advancing / retreating of the cylinder 118b into rotation of the swinging shaft 118a. However, the present invention is not limited to this, and the brush bristles 117 may be brought close to or separated from the corner portion 10a of the roller 10 by rotating the swing shaft 118a in the forward and reverse directions by a motor capable of rotating forward and reverse. Alternatively, a sliding contact body is attached to the tip of the rod of the cylinder, and by moving the rod forward and backward, the sliding contact body is linearly approached and separated from the corner portion 10a of the roller 10 without swinging. (Not shown) may be adopted.

本実施形態の載せ掛け装置11では、ブラシ体11Bは、待機状態にてローラ10および上下反転装置9から離れた場所に退避しているため、上下反転装置9で布類Yを反転させた際にその布類Yがブラシ体11Bに引っ掛かる事態はあまり起こらないが、このような引っ掛かりをより確実に防止するため、図27に示すように、上下反転装置9で反転される布類Yを退避位置にある起立姿勢のブラシ体11Bとローラ10との間に導く板状のカバー119を、ブラシ体11Bの真上かつ上下反転装置9と正対する位置に設けてもよい。 In the mounting device 11 of the present embodiment, the brush body 11B is retracted to a place away from the roller 10 and the upside down device 9 in the standby state, so that when the cloth Y is turned upside down by the upside down device 9. The situation where the cloth Y is caught on the brush body 11B rarely occurs, but in order to prevent such catching more reliably, as shown in FIG. 27, the cloth Y inverted by the upside down device 9 is retracted. A plate-shaped cover 119 that guides between the brush body 11B in the standing posture and the roller 10 at the position may be provided at a position directly above the brush body 11B and facing the upside down device 9.

図28(a)〜(e)を順に参照し、載せ掛け装置11の載せ掛け移動体11Aにより布類Yをローラ10に載せ掛けるにあたり、摺接体としてのブラシ体11Bを作動させて布類Yへの皺や折れ返りの発生を低減ないし防止する各工程について説明する。 With reference to FIGS. 28 (a) to 28 (e) in order, when the cloth Y is mounted on the roller 10 by the loading moving body 11A of the loading device 11, the brush body 11B as a sliding contact body is operated to operate the cloth. Each step of reducing or preventing the occurrence of wrinkles and folds on Y will be described.

図28(a)は、図24を参照して説明したのと同じ状態であり、つまり載せ掛け移動体11Aが所定の進出位置にて上下反転装置9から布類Yを受け取り、そのまま垂れ下げ保持している状態である。上下反転装置9が布類Yを反転し、載せ掛け移動体11Aがその反転した布類Yを受け取る間は、シリンダ118bが伸長し、ブラシ体11Bは上下反転装置9およびローラ10から離れた後退位置で待機している。 FIG. 28A is the same state as described with reference to FIG. 24, that is, the loading moving body 11A receives the cloth Y from the upside-down inversion device 9 at a predetermined advance position and holds the cloth Y as it is. It is in a state of being. While the upside-down flipping device 9 flips the cloth Y and the loading moving body 11A receives the flipped cloth Y, the cylinder 118b extends and the brush body 11B retracts away from the upside-down flipping device 9 and the roller 10. Waiting at the position.

続いて載せ掛け移動体11Aが、図28(b)に示すように、上記所定の進出位置からブラシ体11Bと干渉することのない所定の距離だけ後退すると、シリンダ118bが短縮しブラシ体11Bがその基端部を中心に揺動し、ブラシ毛117が布類Yに摺接するまでローラ10の角部10aに向けて進出する。布類Yに対するブラシ毛117の押し当て力が強すぎると、載せ掛け移動体11Aのチャック111,112から布類Yが脱落したり布類Yがずれたりするので、ブラシ毛117の押し当て力はそのような事態が生じないよう予め適宜設定しておくことができる。この押し当て力は、布類Yの材質に応じて変えてもよい。 Subsequently, as shown in FIG. 28B, when the mounted moving body 11A retracts from the predetermined advance position by a predetermined distance that does not interfere with the brush body 11B, the cylinder 118b is shortened and the brush body 11B is shortened. It swings around the base end portion and advances toward the corner portion 10a of the roller 10 until the brush bristles 117 slide into contact with the cloth Y. If the pressing force of the brush bristles 117 against the cloth Y is too strong, the cloth Y may fall off from the chucks 111 and 112 of the moving body 11A or the cloth Y may shift, so that the pressing force of the brush bristles 117 is applied. Can be appropriately set in advance so that such a situation does not occur. This pressing force may be changed depending on the material of the cloth Y.

続いて載せ掛け移動体11Aが、図28(c)に示すように、布類Yを把持したまま後退すると、ブラシ毛117が布類Yの移動と協働して布類Yを引っ張った状態となるので布類Yの皺は伸ばされる。図28(c)には、布類Yの、載せ掛け移動体11Aで把持された側縁Ycとは反対側の側縁Yd近傍に生じ始めた折れ返りも示されている。 Subsequently, as shown in FIG. 28 (c), when the loading moving body 11A retracts while holding the cloth Y, the brush bristles 117 pull the cloth Y in cooperation with the movement of the cloth Y. Therefore, the wrinkles of the cloth Y are smoothed. FIG. 28 (c) also shows the folds of the cloth Y that have begun to occur in the vicinity of the side edge Yd on the side opposite to the side edge Yc gripped by the mounted moving body 11A.

さらに載せ掛け移動体11Aが図28(d)に示す位置まで後退すると、ブラシ毛117が布類Yの側縁Ydを引っ張るので、布類Yの側縁Yd近傍に生じた折れ返りは矯正される。 Further, when the loading moving body 11A retracts to the position shown in FIG. 28 (d), the brush bristles 117 pull the side edge Yd of the cloth Y, so that the bending caused in the vicinity of the side edge Yd of the cloth Y is corrected. NS.

そして、図28(e)に示すように、載せ掛け移動体11Aが布類Yの把持を解放し布類Yがローラ10上に載せ掛けられると、シリンダ118bが再び伸長して、ブラシ体11Bは元の待機位置へと後退し、上下反転装置9が次の布類Yを反転させることができる退避状態となる。 Then, as shown in FIG. 28E, when the loading moving body 11A releases the grip of the cloth Y and the cloth Y is mounted on the roller 10, the cylinder 118b extends again and the brush body 11B Retreats to the original standby position, and the vertical inversion device 9 is in a retracted state in which the next cloth Y can be inverted.

ローラ10は、図29に示すように、同一軸線上で隣り合って配置された第1部分ローラ102および第2部分ローラ103からなる。第1部分ローラ102は、駆動ベルト105を介してモータ104に接続され該モータ104で回転駆動される。第2部分ローラ103は、駆動ベルト107を介してモータ106に接続され該モータ106で回転駆動される。モータ104,106の回転方向および回転速度は別個独立に制御可能であり、好適には、図30に示すように各部分ローラ102,103の下方にローラの回転軸線と平行に並べられた複数のセンサ群108,109からの検出信号に基づき、ローラ10上の布類Yの向きを正しい向き(例えば布類Yの長手方向が前後方向と一致する向き)に修正できるように、別個独立に制御される。例えば、図29に示すように布類Yがローラ10上に斜めに載せ掛けられていて、図30に示すようにセンサ群108,109のうちセンサ群109だけが布類Yの短辺側の側縁Yeを検知している場合には、この検知結果に基づき、該側縁Yeがセンサ群108,109と平行になって両センサ群108,109が同時に布類Yの短辺側の側縁Yeを検知するまで第1部分ローラ102および第2部分ローラ103の停止、正転、反転が繰り返される。なお、図示例では、各センサ群108,109はそれぞれ5つのセンサからなるが、センサの数はこれに限定されず、処理する布類Yの幅に応じて4つ以下でも6つ以上でもよく、また、処理する布類Yに応じて稼動させるセンサを切り替えるようにしてもよい。 As shown in FIG. 29, the roller 10 includes a first partial roller 102 and a second partial roller 103 arranged adjacent to each other on the same axis. The first partial roller 102 is connected to the motor 104 via the drive belt 105 and is rotationally driven by the motor 104. The second partial roller 103 is connected to the motor 106 via the drive belt 107 and is rotationally driven by the motor 106. The rotation direction and rotation speed of the motors 104 and 106 can be controlled separately and independently, and preferably, as shown in FIG. 30, a plurality of motors 104 and 106 are arranged below each partial roller 102 and 103 in parallel with the rotation axis of the rollers. Based on the detection signals from the sensor groups 108 and 109, the direction of the cloth Y on the roller 10 is controlled separately and independently so that the direction can be corrected to the correct direction (for example, the direction in which the longitudinal direction of the cloth Y coincides with the front-rear direction). Will be done. For example, as shown in FIG. 29, the cloth Y is diagonally mounted on the roller 10, and as shown in FIG. 30, only the sensor group 109 of the sensor groups 108 and 109 is on the short side side of the cloth Y. When the side edge Ye is detected, based on this detection result, the side edge Ye is parallel to the sensor groups 108 and 109, and both sensor groups 108 and 109 are simultaneously on the short side side of the cloth Y. The first partial roller 102 and the second partial roller 103 are repeatedly stopped, forward-rotated, and inverted until the edge Ye is detected. In the illustrated example, each of the sensor groups 108 and 109 is composed of five sensors, but the number of sensors is not limited to this, and may be four or less or six or more depending on the width of the cloth Y to be processed. Alternatively, the sensor to be operated may be switched according to the cloth Y to be processed.
