Description

本願発明は、ランドリー工場等において、洗濯・乾燥後の丸まった状態の矩形布片をきれいに展開させる際の矩形布片の短辺出し装置に関し、特にフェイスタオルやバスタオル等の比較的小面積の矩形布片を対象にした短辺出し装置に関するものである。   The present invention relates to a rectangular cloth piece short-side extracting device when a rolled-up rectangular cloth piece after washing and drying is neatly developed in a laundry factory or the like, and in particular, a relatively small area such as a face towel or a bath towel. The present invention relates to a short side out device for a rectangular cloth piece.

ランドリー工場では、入荷したフェイスタオルやバスタオル（以下、矩形布片という）は、洗濯・乾燥後にきれいに折畳んで出荷されるが、洗濯・乾燥後の矩形布片は、丸まった状態で乾燥機から取出される。   In the laundry factory, face towels and bath towels (hereinafter referred to as rectangular cloth pieces) that are received are folded and shipped cleanly after washing and drying, but the rectangular cloth pieces after washing and drying are in a curled state in the dryer. Taken from.

そして、従来では、一般に、山積み状態の矩形布片群から丸まった状態の矩形布片を１枚ずつ取り分け、その矩形布片から作業員が手作業で１つの短辺側側縁を捜し出して伸展させ、その伸展させた短辺側側縁を折畳み装置の投入コンベア上に載せた後、該矩形布片の後行側を短辺方向に広げて整形しながら折畳み装置側に送り込ませている。   Conventionally, in general, the rectangular cloth pieces in a state of being rounded are separated one by one from the group of stacked rectangular cloth pieces, and an operator manually searches for and extends one short side edge from the rectangular cloth pieces. Then, after the extended short side edge is placed on the input conveyor of the folding device, the trailing side of the rectangular cloth piece is widened in the short side direction and sent to the folding device while shaping.

ところで、ランドリー工場では、１日に大量の矩形布片を展開処理をしなければならないが、上記のように手作業による展開方法では、矩形布片の展開作業が面倒であるとともに、１枚当たりの処理時間が長くなって作業能率が悪かった。   By the way, in a laundry factory, a large amount of rectangular cloth pieces must be unfolded per day. However, in the manual unfolding method as described above, the unfolding work of the rectangular cloth pieces is troublesome and the amount per sheet is large. The processing time was long and the work efficiency was bad.

このような手作業による矩形布片展開方法の問題点を改善するために、本出願人の関連会社から特開２００２−１１３３００号公報に示される矩形布片の展開装置が提案されている。この公知例の矩形布片展開装置は、図２２に示すように、供給コンベア２０１で洗濯・乾燥後の矩形布片を丸めた状態で所定位置まで順次供給し、その所定位置に供給された布片を吊上げ装置２０２で所定高さまで吊上げ、その吊上げた布片を仮保持装置２０３で受け取って仮保持し、仮保持装置２０３で吊下げている布片の任意の箇所を保持して該布片を台板２４３上で水平方向に引き摺って、該布片の終端である布片角端を現出させ（角端出し装置２０４で行われる）、角端取り装置２０５で台板２４３上に現出させた布片角端付近を保持して布片を垂れ下げ支持し（後述の図２３）、角端取り装置２０５で垂れ下げ支持している布片を横引き装置２０６で水平方向に横たわらせ（後述の図２４）、横たわった状態の布片長辺側の角端付近とそこから適宜距離だけ離間する箇所の２位置を２位置保持装置２０７で同高さに保持し（後述の図２５）、該２位置保持装置２０７で保持した布片を縁出しコンベア２０８に載せて布片長辺側の一方の側縁を現出させ（後述の図２５、図２６）、載せ掛け装置２１０により縁出しコンベア２０８上で縁出しされた布片長辺部の２位置を保持して該布片をローラ２０９上を引き摺りながら該ローラ２０９上に載せ掛け、吊下げ装置２１１でローラ２０９上に載せ掛けた布片の一方の短辺側端縁の２箇所を保持して該布片を展開状態で吊下げ、吊下げ装置２１１に吊下げられた展開状態の布片を進退装置２１２により搬送コンベア２１４上に移乗させ得るように構成されている。尚、この図２２の矩形布片展開装置の詳細は、特開２００２−１１３３００号公報に記載されている。   In order to improve such a problem of the rectangular cloth piece unfolding method by manual work, a rectangular cloth piece unfolding apparatus disclosed in Japanese Patent Application Laid-Open No. 2002-113300 has been proposed by an affiliated company of the present applicant. As shown in FIG. 22, the known rectangular cloth piece unfolding apparatus sequentially supplies the cloth pieces that have been washed and dried by the supply conveyor 201 to a predetermined position in a rolled state and supplies the cloth to the predetermined position. The piece is lifted up to a predetermined height by the lifting device 202, the lifted cloth piece is received and temporarily held by the temporary holding device 203, and the cloth piece is held by holding an arbitrary portion of the cloth piece suspended by the temporary holding device 203. Is dragged in the horizontal direction on the base plate 243 so that the corner end of the cloth piece, which is the terminal end of the cloth piece, is exposed (performed by the corner end extracting device 204), and the corner end device 205 is displayed on the base plate 243. The cloth piece is supported by hanging down while holding the vicinity of the corner end of the cloth piece taken out (FIG. 23 to be described later), and the cloth piece hanging down and supported by the corner trimming device 205 is horizontally moved by the horizontal pulling device 206. Warp (see Fig. 24), with the corner edge on the long side of the cloth lying down And two positions at a distance from the appropriate distance are held at the same height by the two-position holding device 207 (FIG. 25 described later), and the cloth pieces held by the two-position holding device 207 are placed on the edging conveyor 208. Then, one side edge of the long side of the cloth piece is exposed (FIGS. 25 and 26 described later), and the two positions of the long side portion of the cloth piece edged on the edge conveyor 208 by the loading device 210 are held. The cloth piece is placed on the roller 209 while being dragged on the roller 209, and the cloth piece is held by holding two places on one short side edge of the cloth piece placed on the roller 209 by the suspending device 211. The cloth piece in the unfolded state suspended by the suspending device 211 can be transferred onto the conveyor 214 by the advance / retreat device 212. Details of the rectangular cloth piece unfolding device shown in FIG. 22 are described in JP-A-2002-113300.

ところで、この図２２の矩形布片展開装置による布片展開工程においては、布片をローラ２０９上に載せ掛ける前に布片の一辺（この公知例の展開装置では布片長辺）を現出させることが必要であるが、この布片の縁（長辺）出しは図２３〜図２６に示すようにして行われる。   By the way, in the cloth piece unfolding step by the rectangular cloth piece unfolding device of FIG. 22, before placing the cloth piece on the roller 209, one side of the cloth piece (the cloth piece long side in the unfolding apparatus of this known example) is exposed. However, the edge (long side) of the cloth piece is formed as shown in FIGS.

まず、図２３に示すように、角端取り装置２０５のチャック２５１で１つの布片角端Ｙｃを保持して布片Ｙを垂れ下げ支持し、その布片角端Ｙｃ付近を横引き装置２０６のチャック２６１で保持する（図２３の符号２６１′）。次に、図２４に示すように、布片角端Ｙｃを保持しているチャック２６１を後退させて布片Ｙを台板２５３とチャック２６１との間で水平方向に横たわらせ、その横たわった状態の布片Ｙの角端Ｙｃ付近とそこから適宜距離だけ離間する箇所の２位置を２位置保持装置２０７の２つのチャック２７１，２７２で同高さに保持する（図２４の符号２７１′，２７２′）。次に、図２５に示すように、２位置保持装置２０７の各チャック２７１，２７２で保持した布片Ｙを縁出しコンベア２０８に載せて布片長辺側の一方の側縁を符号Ｙｂの状態からＹｂ′のように現出させる。その後、各チャック２７１，２７２を開放させると、図２６に示すように、布片Ｙが縁出しコンベア２０８上に落とされるとともに布片の先行側長辺Ｙｂが縁出しされた状態で縁出しコンベア終端部に設置している載せ台２８２上に現出するようになっている。尚、この縁出しされた布片長辺Ｙｂは、載せ掛け装置２１０の２つのチャックで保持されて、ローラ２０９上に載せ掛けられる。   First, as shown in FIG. 23, one cloth piece corner end Yc is held and supported by the chuck 251 of the corner trimming device 205, and the cloth piece Y is suspended and supported. Are held by the chuck 261 (reference numeral 261 'in FIG. 23). Next, as shown in FIG. 24, the chuck 261 holding the cloth piece corner end Yc is moved backward so that the cloth piece Y is laid horizontally between the base plate 253 and the chuck 261 and then laid down. The two positions near the corner end Yc of the cloth piece Y in a state of being in contact with it and at a suitable distance from the corner end Yc are held at the same height by the two chucks 271 and 272 of the two-position holding device 207 (reference numeral 271 ′ in FIG. 24). , 272 '). Next, as shown in FIG. 25, the cloth piece Y held by the chucks 271 and 272 of the two-position holding device 207 is placed on the edging conveyor 208, and one side edge of the cloth piece long side is moved from the state of Yb. It appears as Yb '. Thereafter, when the chucks 271 and 272 are opened, as shown in FIG. 26, the cloth piece Y is dropped onto the edge conveyor 208 and the leading long side Yb of the cloth piece is edged, and the edge conveyor It appears on a platform 282 installed at the terminal end. The edged fabric piece long side Yb is held by the two chucks of the placing device 210 and placed on the roller 209.

特開２００２−１１３３００号公報JP 2002-113300 A

ところで、図２２〜図２６に示す公知の矩形布片展開装置では、図２６に示すように縁出しコンベア２０８の終端部の載せ台２８２上に布片Ｙの一辺（長辺）Ｙｂを縁出しするまでの工程において、図２４に示すように布片Ｙを台板２５３と横引き装置２０６のチャック２６１との間に横引きしている布片Ｙの２位置を２位置保持装置２０７の２つのチャック２７１，２７２で同高さに保持するようにしているが、台板２５３側の布片一端部は該台板２５３上に単に載せているだけなので、該布片Ｙの上縁部分Ｙｅの中間部が下方に撓むことがある。その場合、布片上縁部分Ｙｅにおける、２つのチャック２７１，２７２で掴持する部分の高さに高差が生じることがある。   By the way, in the known rectangular cloth unfolding apparatus shown in FIGS. 22 to 26, as shown in FIG. 26, one side (long side) Yb of the cloth piece Y is edged on the platform 282 at the terminal end of the edge conveyor 208. In the process up to this point, as shown in FIG. 24, two positions of the cloth piece Y that is horizontally drawing the cloth piece Y between the base plate 253 and the chuck 261 of the horizontal drawing apparatus 206 are set to 2 of the two-position holding device 207. The two chucks 271 and 272 are held at the same height, but since one end of the cloth piece on the base plate 253 side is simply placed on the base plate 253, the upper edge portion Ye of the cloth piece Y The middle part of the case may bend downward. In that case, a height difference may occur in the height of the portion gripped by the two chucks 271 and 272 in the cloth piece upper edge portion Ye.

そして、布片Ｙの上縁部分Ｙｅにおける両チャック２７１，２７２の掴持部分に高差が生じると、両チャック２７１，２７２が下動して（符号２７１′２７２）布片上縁部分Ｙｅを掴持するときに、該両チャックがそれぞれ布片上縁部分Ｙｅを掴持できないことがあり、その場合は以後の工程がうまく行えない。即ち、図２５、図２６に示すように、布片長辺Ｙｂの縁出しが行えず、布片Ｙの展張作業が失敗するという問題があった。   When a difference in height occurs between the gripping portions of both the chucks 271 and 272 in the upper edge portion Ye of the cloth piece Y, both chucks 271 and 272 move downward (reference numeral 271'272) to grip the cloth piece upper edge portion Ye. When gripping, the chucks may not be able to grip the cloth upper edge portion Ye, and in this case, the subsequent steps cannot be performed well. That is, as shown in FIG. 25 and FIG. 26, there is a problem that the cloth piece long side Yb cannot be trimmed, and the work of extending the cloth piece Y fails.

このように、矩形布片を丸めた状態から自動で方形状に展開させるようにした矩形布片展開装置において、一連の布片展開工程の中で布片Ｙの１つ側縁（長辺又は短辺）を現出させる処理は重要であり、展開の失敗を極力少なくするためには、どのようにして布片側縁を現出させるかが大きな課題となっている。   In this way, in the rectangular cloth piece unfolding apparatus that automatically unfolds the rectangular cloth piece into a square shape from the rolled state, one side edge (long side or long side) of the cloth piece Y in a series of cloth piece unfolding steps. The process of making the short side appear is important, and in order to minimize the failure of the unfolding, how to make the cloth piece side edge appear is a major issue.

そこで、本願発明は、丸めた状態の矩形布片を自動で方形状に展開させ得るようにした矩形布片展開装置において、矩形布片の１つの側縁（短辺）を確実に現出させ得るようにした矩形布片の短辺出し装置を提供することを目的としている。   Accordingly, the present invention provides a rectangular cloth piece unfolding apparatus that can automatically unfold a rectangular cloth piece in a rounded state into a rectangular shape, and reliably expose one side edge (short side) of the rectangular cloth piece. It is an object of the present invention to provide a short side out device for a rectangular cloth piece obtained.

本願発明は、上記課題を解決するための手段として次の構成を有している。   The present invention has the following configuration as means for solving the above problems.

［本願請求項１の発明］
本願請求項１の発明は、丸めた状態で搬送されてくる矩形布片を自動で方形状に展開させる展開装置に使用される矩形布片の短辺出し装置を対象にしている。 [Invention of Claim 1 of the Present Application]
The invention of claim 1 of the present application is directed to a short side out device for a rectangular cloth piece used in a developing device that automatically unfolds a rectangular cloth piece conveyed in a rolled state into a square shape.

尚、矩形布片の展開装置としては、例えば上記特開２００２−１１３３００号公報に示されるものがあるが、矩形布片を丸めた状態から自動で方形状に展開させるには、次のようにして行われる。   In addition, as a rectangular cloth piece unfolding apparatus, for example, there is one disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 2002-113300, but in order to automatically unfold a rectangular cloth piece from a rounded state into a square shape, it is as follows. Done.

まず、丸めた状態で搬送されてくる矩形布片の任意の箇所を保持して所定高さまで吊上げ、その吊上げた布片の下端（１つの角端となる）を手掛かりにして布片の一辺（短辺）の側縁を現出させ、その一辺の側縁を引き摺り、以後の所定の工程を経ることにより、矩形布片を自動で方形状に展開させる。   First, hold an arbitrary part of the rectangular cloth conveyed in a rolled state and lift it to a predetermined height, and use one side of the cloth piece as a clue to the lower end (which becomes one corner end) of the lifted cloth piece. The side edge of the short side is made to appear, the side edge of the one side is dragged, and the rectangular cloth piece is automatically developed into a rectangular shape through a predetermined process thereafter.

そして、本願請求項１の短辺出し装置は、一連の展開工程において矩形布片の１つ短辺を現出させるためのものである。   And the short side extraction apparatus of Claim 1 of this application is for making one short side of a rectangular cloth piece appear in a series of unfolding processes.

本願請求項１の短辺出し装置は、１つの布片角端を保持して布片を吊下げ状態で支持する角端吊持装置と、該角端吊持装置から吊下げられた布片の下端角端を挟持する下端挟持装置と、角端吊持装置と下端挟持装置とで保持された布片の下部寄り位置にエアを吹き付けて布片下部側を略三角形状に展張させるブロワと、該ブロワによって展張された布片下部側の短辺を略水平姿勢にする姿勢変更装置と、下部側短辺を略水平で直線状に展張させた状態で布片下部側を吸着させる吸着ボックスとを備えている。   The short side out device according to claim 1 of the present application is a corner end suspension device that holds one piece of cloth piece and supports the piece of fabric in a suspended state, and a piece of cloth suspended from the corner end suspension device. A lower end clamping device that clamps the lower end corner of the blower, and a blower that blows air toward the lower portion of the cloth piece held by the corner end suspension device and the lower end holding device to expand the lower side of the cloth piece in a substantially triangular shape A posture changing device for making the short side of the lower part of the cloth stretched by the blower substantially horizontal, and a suction box for sucking the lower part of the cloth piece in a state where the lower side of the lower part is stretched substantially horizontally and linearly And.

上記角端吊持装置には、布片角端を保持するチャックを有し、該チャックで１つの布片角端を保持した状態で布片を垂れ下げ支持し得る。尚、垂れ下げ支持された布片の下端には、上記チャックで保持された１つの布片角端の対角角端が位置するようになる。   The corner end suspension device has a chuck that holds the corner end of the cloth piece, and can support the cloth piece hanging down while holding one corner end of the cloth piece with the chuck. Note that the diagonal end of one corner of the cloth piece held by the chuck is positioned at the lower end of the cloth piece supported to hang down.

角端吊持装置で垂れ下げ支持された布片の下端は、下端挟持装置で挟持されるが、該下端挟持装置で布片下端を挟持した状態では、角端吊持装置と下端挟持装置とで布片の上下２つの対角角端が保持されている。   The lower end of the cloth piece suspended and supported by the corner end suspension device is sandwiched by the lower end sandwiching device, but in the state where the lower end portion of the fabric piece is sandwiched by the lower end sandwiching device, the corner end suspension device and the lower end sandwiching device are The upper and lower diagonal ends of the cloth piece are held.

上記ブロワは、角端吊持装置と下端挟持装置とで保持された上下向き姿勢の布片に対して、その下部寄り位置に略水平方向からエアを吹き付けることにより、布片下部の自由状態にある（保持されていない）角端側をはためかして、布片下部側を略三角形状に展張させるものである。尚、布片下部側が略三角形状に展張された状態では、布片の下部側短辺が傾斜している。   The blower is in a free state at the lower part of the cloth piece by blowing air from the substantially horizontal direction toward the lower part of the cloth piece in the vertical position held by the corner end suspension device and the lower end holding device. A corner end side (not held) is peeled off, and the lower side of the cloth piece is expanded in a substantially triangular shape. In addition, in the state by which the cloth piece lower part side was extended in the substantially triangular shape, the lower part short side of the cloth piece is inclined.

上記姿勢変更装置は、傾斜状態にある布片の下部側短辺を略水平姿勢に変更するためのもので、例えば角端吊持装置による布片上端吊持部を下端挟持装置による布片下端挟持部を中心にして弧回動させることにより、布片の下部側短辺を略水平姿勢に変更できる。   The posture changing device is for changing the lower short side of the cloth piece in an inclined state into a substantially horizontal posture. For example, the cloth piece upper end suspension portion by the corner end suspension device is used as the cloth piece lower end portion by the lower end holding device. By rotating the arc around the pinching portion, the lower short side of the cloth piece can be changed to a substantially horizontal posture.

上記吸着ボックスは、布片下部側を展張状態で吸着させるものであり、該吸着ボックスの布片吸着面には小孔からなる多数の吸気穴が形成されている。そして、吸着ボックス内をバキュームファンで吸引することにより、多数の吸気穴部分で布片下部側を展張状態で吸着させ得るようになっている。   The suction box is for sucking the lower part of the cloth piece in a stretched state, and a plurality of suction holes made up of small holes are formed on the cloth piece suction surface of the suction box. Then, by sucking the inside of the suction box with a vacuum fan, the lower part of the cloth piece can be sucked in a stretched state at a number of intake hole portions.

このように、吸着ボックスの吸着面に布片下部側が吸着された状態では、布片の下部側短辺が略水平で直線状に展張された状態で保持されており、そのことがこの短辺出し装置による布片短辺出し状態となる。   As described above, in the state where the lower side of the cloth piece is adsorbed to the adsorption surface of the adsorption box, the lower side of the cloth piece is held in a state of being stretched in a substantially horizontal and straight line. The cloth piece is brought into a short side out state by the taking out device.

本願請求項１の短辺出し装置では、上記のように最終的に布片下部側を吸着ボックスの吸着面に吸着・保持させることができるので、その下部側短辺が安定姿勢で現出している。そして、吸着ボックスの吸着面で短辺出しされた布片の下部側短辺は、次の工程となる短辺取り装置のチャックで受け取られるが、該下部側短辺が安定姿勢で現出しているので、その下部側短辺の受け取りが確実に行える。   In the short side out device of claim 1 of the present application, the lower side of the cloth piece can be finally sucked and held on the suction surface of the suction box as described above, so that the lower side short side appears in a stable posture. Yes. And the lower side short side of the cloth piece short-sided on the suction surface of the suction box is received by the chuck of the short chamfering device which will be the next step, but the lower side short side appears in a stable posture. Therefore, it is possible to reliably receive the lower side of the lower side.

尚、本願発明の短辺出し装置が使用される矩形布片展開装置には、該短辺出し装置より前工程に、多数の布片を順次丸めた状態で所定位置まで搬送させる供給コンベアと、該供給コンベアの所定位置で待機している布片を吊上げる吊上げ装置と、吊上げた布片の下端部（１つの布片角端）を現出させる角端出し装置と、その１つの布片角端を受け取る角端取り装置とがそれぞれ設けられ、該角端取り装置から１つの布片角端を角端吊持装置で受け取って該布片を垂れ下げ支持する。他方、上記のように本願の短辺出し装置で短辺出しされた布片は、該布片の短辺を短辺取り装置で受け取った後、順次以後の工程を経て方形状に展開される。   In addition, the rectangular cloth piece unfolding apparatus in which the short edge drawing device of the present invention is used has a supply conveyor that conveys a large number of cloth pieces to a predetermined position in a state of being sequentially rounded before the short edge drawing apparatus, A lifting device for lifting a cloth piece waiting at a predetermined position of the supply conveyor, a corner edge taking-out device for exposing the lower end portion (one cloth corner end) of the lifted cloth piece, and the one cloth piece A corner edge receiving device for receiving the corner edge is provided, and one corner of the cloth piece is received from the corner edge removing device by the corner end suspension device, and the cloth piece is suspended and supported. On the other hand, after the short edge of the cloth piece is received by the short edge removing device as described above, the cloth piece which has been short edged by the short edge drawing apparatus of the present application is successively developed into a square shape through the subsequent steps. .

［本願請求項２の発明］
本願請求項２の発明は、上記請求項１の矩形布片の短辺出し装置において、吸着ボックスに吸着させた布片下部側の短辺部分の間隔をもった２箇所を吸着ボックスの吸着面に対して開閉自在に押える２つの押え板を有している。 [Invention of claim 2 of the present application]
The invention according to claim 2 of the present application is the short side out device for the rectangular cloth piece according to claim 1, wherein the suction surface of the suction box has two locations with a short side portion on the lower side of the cloth piece sucked by the suction box. There are two presser plates that can be opened and closed.

各押え板は、例えばシリンダによって、吸着ボックスの吸着面を開放する開位置と該吸着面に接合する閉位置との間で変位させ得るようになっている。そして、布片下部側が吸着ボックス吸着面の前面に対面する前は、各押え板が上記開位置にあって布片下部側が吸着ボックス吸着面の前面で展張可能になっており、該布片下部側が吸着ボックス吸着面に吸着された後に、各押え板が吸着ボックス吸着面に接合する閉位置まで変位するようになっている。   Each presser plate can be displaced, for example, by a cylinder, between an open position where the suction surface of the suction box is opened and a closed position where it is joined to the suction surface. Before the lower part of the cloth piece faces the front surface of the suction box suction surface, each presser plate is in the open position, and the lower part of the cloth piece is expandable on the front surface of the suction box suction surface. After the side is adsorbed to the adsorption box adsorption surface, each presser plate is displaced to a closed position where it is joined to the adsorption box adsorption surface.

この請求項２の短辺出し装置では、上記請求項１のように布片下部側を吸着ボックスの吸着面に吸着させた後に、各押え板で布片下部側の短辺部分の間隔をもった２箇所を押えることができ、布片下部側の短辺部分を一層確実に保持できる。尚、次の工程となる短辺取り工程では、各押え板で布片短辺部分の間隔をもった２箇所を押えた状態で、該両押え板の間の短辺部分を短辺取り装置のチャックで受け取るようになっているが、各押え板で布片短辺部分を押えていると、短辺取り装置のチャックで布片短辺を掴持するときに該布片短辺が動かない。   In the short side picking device according to the second aspect, after the lower part of the cloth piece is adsorbed to the adsorption surface of the adsorption box as in the first aspect, each holding plate has an interval of the short side part on the lower side of the cloth piece. 2 places can be pressed, and the short side portion on the cloth piece lower side can be held more reliably. In the short chamfering step, which is the next step, each presser plate is pressed at two locations with a gap between the short sides of the cloth pieces, and the short side portion between the presser plates is used as a chuck for the short chamfering device. However, if the short side portion of the cloth piece is pressed by each pressing plate, the short side of the cloth piece does not move when the short side of the cloth piece is gripped by the chuck of the short chamfering device.

本願請求項１の矩形布片の短辺出し装置では、１つの布片短辺を現出させるのに、上記のように角端吊持装置と下端挟持装置とで布片の上下各端部（上下の各対角角端）を保持した状態で、ブロワにより下部側短辺を現出させ、姿勢変更装置により下部側短辺を略水平姿勢にし、吸着ボックスで布片の下部側短辺を略水平で直線状に展張させた状態で吸着させ得るようになっているので、布片の下部側短辺を確実に且つ安定姿勢で現出させることができるという効果がある。尚、このように布片の下部側短辺を確実に且つ安定姿勢で現出させることができると、次の工程となる短辺取り工程において布片短辺を確実に受け取ることができ、以後の工程において矩形布片の展開作業を正常に行える。   In the short side out device of the rectangular cloth piece according to claim 1 of the present application, in order to make one short piece of the cloth appear, the upper and lower ends of the cloth piece are formed by the corner end suspension device and the lower end holding device as described above. While holding (upper and lower diagonal ends), the lower side of the lower side is made to appear by the blower, the lower side of the lower side is brought to a substantially horizontal position by the posture change device, and the lower side of the lower side of the cloth piece by the suction box Can be adsorbed in a state of being stretched in a substantially horizontal and linear shape, so that there is an effect that the lower side of the cloth piece can be reliably and stably exposed. In addition, if the lower side of the cloth piece can be reliably and stably exposed in this manner, the short side of the cloth piece can be reliably received in the next short chamfering process, and thereafter The rectangular cloth piece can be normally developed in the process.

又、本願請求項２の矩形布片の短辺出し装置では、吸着ボックスの吸着面に布片下部側を吸着させた後、該布片下部側の短辺部分の２箇所を各押え板で押えることができるので、布片の下部側短辺を一層安定姿勢で保持することができる（短辺取り装置のチャックで布片短辺を掴持する作業が確実に行える）という効果がある。   Further, in the short side out device of the rectangular cloth piece according to claim 2 of the present application, after the cloth lower part side is adsorbed to the adsorbing surface of the adsorption box, the presser plate is used to place two places on the short side part of the cloth piece lower side. Since the cloth can be pressed, the lower side of the cloth piece can be held in a more stable posture (the work of grasping the cloth piece short side with the chuck of the short chamfering device can be performed reliably).

供給コンベア１（図１及び図２）は、幅方向に分割した２条の分割ベルト１ａ，１ｂを小間隔の空所１ｃを隔てて左右２本の共通軸に巻き掛けたもので、モータ１８で左から右に走行するようになっている。両分割ベルト間の空所１ｃの終端寄り位置には検出器（光電管）１９が設けられている。そして、図２に示すように、供給コンベア１の始端部上に載せられた布片Ｙが終端寄り位置の検出器１９で検出される位置（図２に符号Ｙ′で示す鎖線図示位置）まで搬送されたときに、該検出器１９からの信号でモータ１８を停止させる（供給コンベア１が停止する）ようになっている。従って、供給コンベア１上に供給される各布片Ｙは、順次供給コンベア１の終端寄りの所定位置（停止位置）まで搬送されてそこで待機するようになっている。   The supply conveyor 1 (FIGS. 1 and 2) is formed by winding two divided belts 1a and 1b divided in the width direction around two common shafts on the left and right sides with a small space 1c therebetween. It is designed to run from left to right. A detector (photoelectric tube) 19 is provided at a position near the end of the space 1c between the two divided belts. As shown in FIG. 2, the cloth piece Y placed on the starting end of the supply conveyor 1 is detected by the detector 19 near the end position (the position indicated by the chain line in FIG. 2). When transported, the motor 18 is stopped by the signal from the detector 19 (the supply conveyor 1 is stopped). Accordingly, each piece of cloth Y supplied onto the supply conveyor 1 is sequentially conveyed to a predetermined position (stop position) near the end of the supply conveyor 1 and waits there.

吊上げ装置２（図１、図２）は、布片Ｙの任意箇所を保持するチャック２１と該チャック２１を昇降させる昇降装置（この実施例ではシリンダ）２２とを有している。又、この吊上げ装置２は、モータ２３と索（タイミングベルト）２４からなる左右動装置により、供給コンベア１上の布片停止位置の直上方位置と角端出し装置３の両ローラ３１，３２（後述する）の直上方位置（符号２′の位置）との間で左右に移動せしめられる。   The lifting device 2 (FIGS. 1 and 2) includes a chuck 21 that holds an arbitrary portion of the cloth piece Y and a lifting device (cylinder in this embodiment) 22 that lifts and lowers the chuck 21. Further, the lifting device 2 is driven by a left-right motion device comprising a motor 23 and a cable (timing belt) 24, and a position immediately above the cloth piece stopping position on the supply conveyor 1 and both rollers 31, 32 ( It is moved to the left and right between the position immediately above (described later) (position 2 ').

角端出し装置３（図２〜図８）は、布片Ｙの上下中間位置を挟持して該布片Ｙを上方に繰り上げる作用をする一対のローラ３１，３２を有している。この各ローラ３１，３２は、左右向きで前後に並置している。又、この各ローラ３１，３２は、一方のローラ３１が基準側取付台３３の下部寄り位置に支持され、他方のローラ３２が揺動側取付台３４の下部寄り位置に支持されている。   The corner edge sticking device 3 (FIGS. 2 to 8) has a pair of rollers 31 and 32 that sandwich the cloth Y and move the cloth Y upward. The rollers 31 and 32 are juxtaposed in the left-right direction. Each of the rollers 31 and 32 is supported such that one roller 31 is supported at a position closer to the lower part of the reference side mounting base 33 and the other roller 32 is supported at a position closer to the lower part of the swinging side mounting base 34.

揺動側取付台３４の下部側（ローラ３２の支持側）は基準側取付台３３に対してシリンダ３８により離間方向（図２の状態）に揺動せしめ得るようになっており、該揺動側取付台３４が離間方向に揺動した状態では、その揺動側取付台３４に支持されているローラ３２が図２及び図５に符号３２′で示すように基準側取付台３３のローラ３１に対して離間するようになっている。   The lower side of the swing side mounting base 34 (the support side of the roller 32) can be swung in the separation direction (state shown in FIG. 2) by the cylinder 38 with respect to the reference side mounting base 33. In a state where the side mounting base 34 swings in the separation direction, the roller 32 supported by the swinging side mounting base 34 is the roller 31 of the reference side mounting base 33 as indicated by reference numeral 32 'in FIGS. Are spaced apart from each other.

各ローラ３１，３２は、モータ３５によりプーリ・ベルト・ギヤ等からなる動力伝達機構３６によって、両ローラ間に挟持される布片Ｙを上方に繰り上げる方向（図６の矢印方向）に回転される。   Each of the rollers 31 and 32 is rotated by a power transmission mechanism 36 including a pulley, a belt, a gear, and the like by a motor 35 in a direction in which the cloth piece Y sandwiched between the two rollers is lifted upward (in the arrow direction in FIG. 6). .

両ローラ３１，３２が接合した状態（図５〜図７）では、その接合部の上下にクサビ形の空間部ができる。そして、両ローラ３１，３２間の基部側位置には、該接合部の下面側直近位置をローラ長さ方向に監視する検出器（光電管）３７が設置されている。この検出器３７は、両ローラ３１，３２の接合部の下面側直近位置に布片Ｙが存在するか否かを検出するものである。尚、この検出器３７は、基準側取付台３３の右側外側面に取付けられている。   In a state where both rollers 31 and 32 are joined (FIGS. 5 to 7), a wedge-shaped space is formed above and below the joined portion. A detector (photoelectric tube) 37 that monitors the position closest to the lower surface side of the joint in the roller length direction is installed at the base side position between the rollers 31 and 32. The detector 37 detects whether or not the cloth piece Y is present at a position closest to the lower surface side of the joint portion between the rollers 31 and 32. The detector 37 is attached to the right outer surface of the reference side mounting base 33.

このように、検出器３７を、両ローラ３１，３２の接合部の下面側直近位置を監視するように設置すると、後述するように布片下端Ｙｃが両ローラ接合部に近接したことを検出できる。   As described above, when the detector 37 is installed so as to monitor the position closest to the lower surface side of the joint portion between the rollers 31, 32, it can be detected that the cloth piece lower end Yc is close to the both roller joint portion as will be described later. .

両ローラ３１，３２（及び各取付台３３，３４）は、反転装置（この実施例ではモータを使用）３９により上下裏返しに反転させ得るようにしている。即ち、両ローラ３１，３２（及び各取付台３３，３４）を反転装置（モータ）３９により、図５に実線図示する状態から鎖線図示する状態までの角度１８０°の範囲で弧回動させ得るようになっている。尚、両ローラの反転中心は、両ローラの接合部の延長線上に位置させている。   The rollers 31 and 32 (and the mounting bases 33 and 34) can be reversed upside down by a reversing device 39 (using a motor in this embodiment). That is, the rollers 31 and 32 (and the mounting bases 33 and 34) can be arc-turned by a reversing device (motor) 39 within an angle range of 180 ° from the state shown by the solid line to the state shown by the chain line in FIG. It is like that. In addition, the reversal center of both rollers is located on the extended line of the junction part of both rollers.

この角端出し装置３は、次のように機能する。まず、図２に示すように、吊上げ装置２が布片Ｙを吊上げて該吊上げ装置２が両ローラ３１，３２の直上方（符号２′の位置）に移動してくる前は、一方のローラ３２が符号３２′のように他方のローラ３１から離間した位置で待機している。尚、吊上げ装置２のチャック２１は、供給コンベア１上にある丸めた状態の布片Ｙの任意の箇所を掴持して吊上げるが、吊上げられた布片Ｙの下端Ｙｃには、多くの場合、１つの布片角端が位置するようになる。   The corner edge extracting device 3 functions as follows. First, as shown in FIG. 2, before the lifting device 2 lifts the cloth piece Y and the lifting device 2 moves directly above the rollers 31 and 32 (position 2 '), one of the rollers 32 stands by at a position separated from the other roller 31 as indicated by reference numeral 32 '. The chuck 21 of the lifting device 2 grips and lifts an arbitrary portion of the rolled cloth piece Y on the supply conveyor 1. In this case, one corner of the cloth piece is positioned.

そして、布片Ｙを吊上げた吊上げ装置２が鎖線図示する位置（符号２′の位置）まで移動するときに、吊上げ布片Ｙの下部側が両ローラ３１，３２′間の間隔内に進入し、その後にローラ３２′が閉動作して両ローラ３１，３２で吊上げ布片Ｙの上下中間位置を両側から挟持する。その後、吊上げ装置２のチャック２１′が開放して、図３に示すように布片Ｙの上下中間部が両ローラ３１，３２で挟持された状態で布片上半部がローラ３１，３２に載置される。このとき、図６に示すように、布片Ｙにおける両ローラ３１，３２で挟持されている部分（両ローラ接合部）より下方部分は垂れ下げられていて、検出器３７が布片の存在を検出している（ＯＮ状態である）。尚、布片垂れ下げ部分の下端Ｙｃには、多くの場合、１つの布片角端が位置している。   When the lifting device 2 that lifts the cloth piece Y moves to the position indicated by the chain line (position 2 '), the lower side of the lifting cloth piece Y enters the space between the rollers 31, 32', Thereafter, the roller 32 'is closed and the upper and lower intermediate positions of the lifted cloth piece Y are clamped from both sides by the rollers 31, 32. Thereafter, the chuck 21 ′ of the lifting device 2 is opened, and the upper half of the cloth piece is placed on the rollers 31 and 32 with the upper and lower intermediate parts of the cloth piece Y held between the rollers 31 and 32 as shown in FIG. Placed. At this time, as shown in FIG. 6, the lower part of the cloth piece Y is hung down from the part sandwiched between the rollers 31 and 32 (joint part of both rollers), and the detector 37 detects the presence of the cloth piece. Detected (ON state). In many cases, one corner end of the cloth piece is located at the lower end Yc of the hanging part of the cloth piece.

次に、モータ３５が布片繰り上げ側に作動して両ローラ３１，３２を図６の矢印方向に回転させ、布片垂れ下げ部分を上方に繰り上げていく。そして、図７に示すように、布片垂れ下げ部の下端Ｙｃが検出器３７の監視位置より上方まで繰り上げられると、該検出器３７が布片非検出状態（ＯＦＦ）となり、直ちにモータ３５を停止する信号が発せられる。尚、検出器３７が布片検出状態（ＯＮ）から布片非検出状態（ＯＦＦ）になったときが、特許請求範囲中の両ローラ接合部の下面側直近位置に布片角端Ｙｃが位置したことを検出したときである。   Next, the motor 35 is actuated to the cloth piece raising side to rotate both rollers 31 and 32 in the direction of the arrow in FIG. 6 and raise the cloth piece hanging portion upward. Then, as shown in FIG. 7, when the lower end Yc of the cloth suspending portion is raised above the monitoring position of the detector 37, the detector 37 enters the cloth non-detection state (OFF), and the motor 35 is immediately turned off. A signal to stop is issued. When the detector 37 changes from the cloth piece detection state (ON) to the cloth piece non-detection state (OFF), the cloth piece corner end Yc is positioned at a position closest to the lower surface side of both roller joints in the claims. This is when it is detected.

この図７の状態では、両ローラ３１，３２の接合部に布片垂れ下げ部分の下端（１つの布片角端）Ｙｃの直近位置が位置している。   In the state of FIG. 7, the closest position of the lower end (one piece corner end) Yc of the cloth piece hanging portion is located at the joint portion between the rollers 31 and 32.

次に、図７の状態から、反転装置（モータ）３９により、両ローラ３１，３２（及び両取付台３３，３４）が上下裏返しに反転され、図８に示すように両ローラ３１，３２の接合部で１つの布片角端Ｙｃを挟持した状態で布片全体を棒状に垂れ下げる。   Next, from the state of FIG. 7, both rollers 31, 32 (and both mounting bases 33, 34) are reversed upside down by a reversing device (motor) 39, and as shown in FIG. The entire cloth piece is hung down in a rod shape with one cloth piece corner end Yc held between the joints.

図８に示すように、両ローラ３１，３２の接合部から垂れ下げられた布片Ｙは、角端取り装置４に受け取られるが、この角端取り装置４は、図１及び図９に示すように、チャック４１と、該チャック４１を左右に進退させる左右動用シリンダ４２と、該左右動用シリンダ４２とともにチャック４１を前後動させる前後動用シリンダ４３とを有している。チャック４１は、図６〜図８に示すように両ローラ接合部の下面側近傍高さ位置で左右及び前後に移動せしめられる。   As shown in FIG. 8, the cloth piece Y hung down from the joint part of both the rollers 31 and 32 is received by the corner | angular edge removal apparatus 4, This corner | angular edge removal apparatus 4 is shown in FIG.1 and FIG.9. As described above, the chuck 41, the left / right moving cylinder 42 for moving the chuck 41 back and forth, and the forward / backward moving cylinder 43 for moving the chuck 41 back and forth together with the left / right moving cylinder 42 are provided. As shown in FIGS. 6 to 8, the chuck 41 is moved left and right and back and forth at the height position near the lower surface side of both roller joint portions.

そして、この角端取り装置４は、チャック４１が図１に示す後側待機位置（後述する角端吊持装置５のチャック５１の直下位置）にある状態から、前後動用シリンダ４３が伸長して該チャックを前側待機位置まで移動させ（図６〜図８の状態、及び図９の実線図示状態となる）、布片Ｙが図８の状態及び図９の実線図示状態に垂れ下げられたときに左右動用シリンダ４２が縮小してチャック４１で垂れ下げ布片Ｙの上端近傍位置を掴持して該チャックを図９の符号４１Ａの位置まで移動させ、次に前後動用シリンダ４３が縮小してチャックを符号４１Ｂの位置まで移動させ、続いて左右動用シリンダ４２が伸長してチャックを符号４１Ｃの位置まで移動させる（この符号４１Ｃのチャック位置が布片受け渡し位置となる）。尚、その間に布片は、符号Ｙの位置から、チャック４１に吊持された状態で、Ｙ1の位置、Ｙ2の位置を経て、Ｙ3の位置まで移動する。 In this corner chamfering device 4, when the chuck 41 is in the rear standby position shown in FIG. 1 (a position directly below the chuck 51 of the corner end lifting device 5 described later), the longitudinal movement cylinder 43 is extended. When the chuck is moved to the front standby position (the state shown in FIGS. 6 to 8 and the solid line shown in FIG. 9), and the cloth piece Y is hung down to the state shown in FIG. 8 and the solid line shown in FIG. Next, the left / right cylinder 42 contracts and the chuck 41 holds the position near the upper end of the cloth piece Y to move the chuck to the position 41A in FIG. The chuck is moved to the position of reference numeral 41B, and then the left and right moving cylinder 42 is extended to move the chuck to the position of reference numeral 41C (the chuck position of reference numeral 41C is the cloth piece delivery position). In the meantime, the cloth piece moves from the position of Y to the position of Y 3 through the position of Y 1 and the position of Y 2 while being suspended from the chuck 41.

角端取り装置４のチャック４１で受け取った布片Ｙは、図１０に示すように、チャック４１で掴持した部分の上に若干高さだけ突出しているが、この突出部（符号Ｙｃ部分）は布片Ｙの１つの角端Ｙｃである。   As shown in FIG. 10, the cloth piece Y received by the chuck 41 of the corner trimming device 4 protrudes slightly above the portion gripped by the chuck 41, but this protruding portion (reference Yc portion). Is one corner end Yc of the cloth piece Y.

角端取り装置４のチャック４１で保持された布片Ｙは、角端吊持装置５で受け取られる。この角端吊持装置５は、図１及び図１０に示すように、チャック５１と、該チャック５１を前後動させる第１の前後動用シリンダ５２と、該第１の前後動用シリンダ５２ごとチャック５１を前後動させる第２の前後動用シリンダ５３と、それらの全体（５１，５２，５３）を上下動させる上下動装置（モータ５４及び索５５）とを有している。尚、角端吊持装置５は、後述の短辺出し装置６の一部として機能するものである。   The cloth piece Y held by the chuck 41 of the corner edge picking device 4 is received by the corner edge lifting device 5. As shown in FIGS. 1 and 10, the corner end suspension device 5 includes a chuck 51, a first front / rear movement cylinder 52 that moves the chuck 51 back and forth, and the first front / rear movement cylinder 52 together with the chuck 51. And a second vertically moving cylinder 53 for vertically moving and a vertically moving device (motor 54 and cable 55) for vertically moving all of them (51, 52, 53). In addition, the corner end suspension device 5 functions as a part of a short side out device 6 described later.

この角端吊持装置５のチャック５１は、図１０に示すように、受け渡し位置にある角端取り装置４のチャック４１の直上方で待機している。そして、角端取り装置４のチャック４１が布片Ｙを保持して受け渡し位置まで移動してきたときに、モータ５４が下動側に作動して角端吊持装置５のチャック５１を角端取り装置側チャック４１に近接する位置（符号５１′の位置）まで降下させ、そこで該角端吊持装置側チャック５１で布片Ｙの上端部（１つの布片角端Ｙｃ）を角端取り装置側チャック４１から受け取るようになっている。そして、角端吊持装置側チャック５１で布片上端部（１つの布片角端Ｙｃ）を受け取った後、モータ５４が上動側に作動して布片Ｙを図１１に示す高さまで吊上げる。この角端吊持装置５のチャック５１で布片Ｙを吊上げた状態（図１１）では、１つの布片角端Ｙｃが該チャック５１で掴持されている一方、その掴持角端Ｙｃの対角位置にある１つの布片角端Ｙｄが吊上げ布片Ｙの最下端に位置するようになる。   As shown in FIG. 10, the chuck 51 of the corner end suspension device 5 stands by just above the chuck 41 of the corner end removal device 4 at the delivery position. When the chuck 41 of the corner edge picking device 4 holds the cloth piece Y and moves to the delivery position, the motor 54 operates downward to remove the chuck 51 of the corner edge lifting device 5. The upper end portion (one piece corner end Yc) of the cloth piece Y is lowered by the corner end suspension device side chuck 51 so as to be lowered to a position close to the apparatus side chuck 41 (position 51 '). It is adapted to receive from the side chuck 41. Then, after receiving the upper end portion of the cloth piece (one cloth piece corner end Yc) by the corner end lifting device side chuck 51, the motor 54 operates upward to suspend the cloth Y to the height shown in FIG. increase. In a state where the cloth piece Y is lifted by the chuck 51 of the corner end lifting device 5 (FIG. 11), one cloth piece corner end Yc is gripped by the chuck 51, while the gripping corner end Yc One corner piece Yd at the diagonal position is positioned at the lowermost end of the lifted cloth piece Y.

角端吊持装置５で吊上げられた布片Ｙは、図１１〜図１４に示すように短辺出し装置６によって布片下部側の短辺Ｙａ（図１３、図１４）が現出される。この短辺出し装置６は、角端吊持装置５のチャック５１から垂れ下げられた布片Ｙの下端（対角角端Ｙｄとなる）を挟持する下端挟持装置６１と、チャック５１と下端挟持装置６１とで布片Ｙの２つの対角角端Ｙｃ，Ｙｄを保持した状態で布片Ｙの下端側短辺を広げる作用をするブロワ６５と、該ブロワ６５によって展張された布片下部側の短辺Ｙａを略水平姿勢に変更する姿勢変更装置（この姿勢変更装置は、この実施例では角端吊持装置５のシリンダ５２とモータ５４とで担当している）と、吊下げ布片Ｙの下部側部分を広げた状態で吸着させる吸着ボックス６６と、該吸着ボックス６６に吸着させた布片Ｙの下部側部分を押える２つの押え板７０，７０とを有している。   As shown in FIGS. 11 to 14, the fabric piece Y lifted by the corner end suspension device 5 has a short side Ya on the lower side of the fabric piece (FIG. 13, FIG. 14). . The short side out device 6 includes a lower end clamping device 61 that clamps a lower end (becomes a diagonal end Yd) of the cloth piece Y suspended from the chuck 51 of the corner end suspension device 5, and a chuck 51 and the lower end clamping unit.

下端挟持装置６１は、図１１〜図１３に示すように、それぞれシリンダ６２，６２で一対の挟持片６３，６３を近接・離間方向に進退操作させるようにしたものである。この下端挟持装置６１は、角端吊持装置５による布片受取り位置（図１１のチャック５１の位置の直下）よりやや後側において、各挟持片６３，６３が左右各側から近接・離間するように設置されている。尚、角端吊持装置５のチャック５１で吊下げている布片Ｙは、角端吊持装置５の前後動用シリンダ５３を伸長させることによって、両挟持片６３，６３間の直上方に位置させることができる。   As shown in FIGS. 11 to 13, the lower end clamping device 61 is configured such that a pair of clamping pieces 63 and 63 are advanced and retracted in the approaching / separating direction by cylinders 62 and 62, respectively. In this lower end clamping device 61, the clamping pieces 63, 63 are moved closer to and away from the left and right sides slightly behind the cloth piece receiving position (just below the position of the chuck 51 in FIG. 11) by the corner end lifting device 5. It is installed as follows. In addition, the cloth piece Y suspended by the chuck 51 of the corner end suspension device 5 is positioned directly above both the sandwiching pieces 63 and 63 by extending the forward / backward movement cylinder 53 of the corner end suspension device 5. Can be made.

下端挟持装置６１の各挟持片６３，６３には、図１２に示すように両挟持片６３，６３間に布片Ｙが存在するか否かを検出する一対（発光側と受光側）の検出器（光電管）６４，６４が設けられている。この検出器６４，６４は、吊上げられていく布片Ｙの最下端（対角角端）Ｙｄを検出するものである。尚、吊上げた布片Ｙの最下端Ｙｄの位置は、前後方向に若干バラツキがあるので、この実施例では左右一対の検出器６４，６４を前後方向に小間隔をもって３組設置して、該３組の検出器６４，６４が全てＯＮになった時点で、布片Ｙの下端（１つの対角角端）Ｙｄが挟持片６３，６３の挟持部高さに位置したと判断するようにしている。   As shown in FIG. 12, a pair of detection (light emitting side and light receiving side) for detecting whether or not the cloth piece Y is present between the holding pieces 63, 63 is provided in each holding piece 63, 63 of the lower end holding device 61. Units (phototubes) 64, 64 are provided. The detectors 64 and 64 detect the lowermost end (diagonal end) Yd of the cloth piece Y being lifted. Since the position of the lowermost end Yd of the suspended cloth piece Y slightly varies in the front-rear direction, in this embodiment, three pairs of left and right detectors 64, 64 are installed at small intervals in the front-rear direction. When all the three sets of detectors 64 and 64 are turned on, it is determined that the lower end (one diagonal end) Yd of the cloth piece Y is positioned at the holding portion height of the holding pieces 63 and 63. ing.

そして、この各検出器６４，６４から布片下端検出信号が発せられると、角端吊持装置５のモータ５４を停止させ、下端挟持装置６１の各シリンダ６２，６２を伸長させて、図１２に鎖線図示するように布片下端部（対角角端）Ｙｄ′を両挟持片６３，６３で挟持するようになっている。   When the cloth piece lower end detection signal is generated from each of the detectors 64, 64, the motor 54 of the corner end suspending device 5 is stopped, and the cylinders 62, 62 of the lower end nip device 61 are extended, and FIG. As shown in the chain line, the lower end portion (diagonal end) Yd ′ of the cloth piece is held between the holding pieces 63 and 63.

ブロワ６５は、図１３に示すように布片Ｙの上下対角角端Ｙｃ，Ｙｄをそれぞれ角端吊持装置５のチャック５１と下端挟持装置６１（両挟持片６３，６３）で保持した状態で、その布片Ｙの下部寄り位置に向けてエアＡを吹き付けることで該布片下部寄り部分をはためかせて、チャック５１と挟持片６３，６３間で保持している布片Ｙを図１３の符号Ｙ′のように略三角形状に展張させるようになっている。このとき、略三角形状に展張した布片Ｙ′の下部側短辺Ｙａがほぼ直線状に展張される。   As shown in FIG. 13, the blower 65 holds the upper and lower diagonal ends Yc and Yd of the cloth piece Y by the chuck 51 and the lower end holding device 61 (both holding pieces 63 and 63) of the corner end suspension device 5, respectively. Then, by blowing air A toward the lower part of the cloth piece Y, the cloth piece lower part is flapped, and the cloth piece Y held between the chuck 51 and the sandwiching pieces 63, 63 is shown in FIG. As shown by reference numeral 13 in FIG. At this time, the lower short side Ya of the cloth piece Y ′ stretched in a substantially triangular shape is stretched in a substantially straight line shape.

又、上記のように略三角形状に展張させた布片Ｙ′（図１３）は、その上端Ｙｃを保持するチャック５１を姿勢変更装置（シリンダ５２とモータ５４）により布片下端Ｙｄの挟持部（両挟持片６３，６３による挟持部）を中心にして後方且つ下方に移動させると、チャック５１′による布片上端保持部と両挟持片６３，６３による布片下端保持部とで保持されている布片が符号Ｙ″（図１３）で示す姿勢になり、そのとき布片Ｙ″の下部側短辺が符号Ｙａ′で示すように略水平になる。尚、角端吊持装置５のチャックを符号５１の位置から符号５１′の位置に移動させるには、モータ５４を下動側に作動させるとともに第１のシリンダ５２を縮小させることで行える。   Further, the cloth piece Y ′ (FIG. 13) expanded in a substantially triangular shape as described above has a chuck 51 for holding the upper end Yc of the cloth piece Y ′ held by the posture changing device (cylinder 52 and motor 54). When it is moved rearward and downward with the center (the clamping part by both clamping pieces 63, 63), it is held by the cloth piece upper end holding part by the chuck 51 'and the cloth piece lower end holding part by the both clamping pieces 63, 63. The cloth piece is in the posture indicated by the symbol Y ″ (FIG. 13), and the lower side of the cloth piece Y ″ is then substantially horizontal as indicated by the symbol Ya ′. The chuck of the corner end suspension device 5 can be moved from the position of reference numeral 51 to the position of reference numeral 51 ′ by operating the motor 54 downward and reducing the first cylinder 52.

吸着ボックス６６は、その右側面が上記略三角形状に展張される布片Ｙ″の左側に近接するように設置されている。この吸着ボックス６６の右側面には、そのほぼ全面に小孔からなる多数の吸気穴６７，６７・・が形成されており、吸着ボックス６６内をバキュームファン６９で吸引することによりボックス右側面（吸気穴６７形成面）に布片の下部寄り展張部分を吸着させ得るようになっている。   The suction box 66 is installed so that the right side surface thereof is close to the left side of the cloth piece Y ″ that is expanded in the above-mentioned triangular shape. Are formed, and by sucking the inside of the suction box 66 with a vacuum fan 69, the lower stretch portion of the cloth piece is sucked on the right side of the box (the suction hole 67 forming surface). To get.

吸着ボックス６６の下面部には、前後中央部からやや前側に寄った位置に、上方に向けて凹入する適宜容積の凹部６８が形成されている。この凹部６８は、後述する（図１５）ように短辺取り装置８の２つのチャック８１，８２を下方から進入させるためのものである。   On the lower surface portion of the suction box 66, a concave portion 68 having an appropriate volume that is recessed upward is formed at a position slightly closer to the front side from the front and rear center portion. The recess 68 is for allowing the two chucks 81 and 82 of the short chamfering device 8 to enter from below as described later (FIG. 15).

又、吸着ボックス６６の右側面（吸気穴形成面）下端部には、凹部６８を挟んでその両側に布片Ｙ″（図１３）の下辺部分を押える２つの押え板７０，７０が設けられている。この各押え板７０，７０は、それぞれシリンダ７１，７１によって水平向き姿勢（図１１、図１３）と吸着ボックス右側面に接合する上向きで姿勢（図１４）との間で上下に揺動させ得るようになっている。   Further, at the lower end portion of the right side surface (intake hole forming surface) of the suction box 66, two press plates 70, 70 are provided on both sides of the recess 68 to press the lower side portion of the cloth piece Y ″ (FIG. 13). The presser plates 70 and 70 swing up and down between a horizontal posture (FIGS. 11 and 13) and an upward posture (FIG. 14) joined to the right side surface of the suction box by the cylinders 71 and 71, respectively. It can be moved.

この各押え板７０，７０は、通常は水平姿勢（開位置となる）に開放されているが、布片が図１３の符号Ｙ″で示す姿勢（下端短辺Ｙａ′が水平）で吸着ボックス６６の右側面に吸着された後、図１４に示すようにそれぞれシリンダ７１，７１で立ち起こされて（閉位置となる）、該各押え板７０，７０で布片の下辺部を前後に間隔をもった２位置で押えることができるようになっている。そして、図１４に示すように、両押え板７０，７０で布片Ｙの下辺部を押えた状態では、凹部６８部分に布片の下部側短辺Ｙａが直線状態で保持されるようになる。尚、両押え板７０，７０で布片下辺部を押えた後、角端吊持装置５のチャック５１が開放して、布片の上部側が吸着ボックス６６の上部に載せられる。   Each of the presser plates 70, 70 is normally opened in a horizontal position (becomes an open position). However, the suction piece is in a position indicated by a symbol Y ″ in FIG. 13 (the lower end short side Ya ′ is horizontal). After being adsorbed by the right side surface of 66, it is raised by cylinders 71, 71 as shown in FIG. 14 (to be in the closed position), and the lower sides of the cloth pieces are spaced forward and backward by the press plates 70, 70. 14, when the lower side portion of the cloth piece Y is pressed by the two holding plates 70, 70, the cloth piece is placed in the recess 68 portion as shown in FIG. The lower side Ya of the lower edge of the cloth is held in a straight line, and after the lower edge of the cloth piece is pressed by the holding plates 70, 70, the chuck 51 of the corner end suspension device 5 is opened, and the cloth The upper side of the piece is placed on the upper portion of the suction box 66.

吸着ボックス６６は、シリンダ７２によって図１４の実線図示位置と鎖線図示位置（符号６６′の位置）の間で左右に進退せしめられる。尚、符号７３は、吸着ボックス６６のレールである。   The suction box 66 is moved forward and backward by the cylinder 72 between the position shown by the solid line in FIG. 14 and the position shown by the chain line (position 66 '). Reference numeral 73 denotes a rail of the suction box 66.

短辺取り装置８は、図１４及び図１５に示すように、吸着ボックス右側面の凹部６８部分で展張している布片下辺部（下部側短辺Ｙａ）を受け取るものである。そして、この短辺取り装置８は、図１４〜図１７に示すように、固定側と可動側の２つのチャック８１，８２と、可動側チャック８２を固定側チャック８１に近接・離間させるシリンダ８３と、両チャック８１，８２を上向きと横向き（左向き）に変更させる姿勢変更装置（シリンダ）８５と、それら（８１，８２，８３，８５）を上下動させる上下動装置（モータ８６及び索８７）とを有している。   As shown in FIGS. 14 and 15, the short chamfering device 8 receives the cloth piece lower side portion (lower side short side Ya) that is stretched at the concave portion 68 on the right side surface of the suction box. 14 to 17, the short chamfering device 8 includes two chucks 81 and 82 on the fixed side and the movable side, and a cylinder 83 that moves the movable side chuck 82 toward and away from the fixed side chuck 81. A posture changing device (cylinder) 85 that changes both chucks 81 and 82 upward and sideways (leftward), and a vertical movement device (motor 86 and rope 87) that moves them (81, 82, 83, and 85) up and down. And have.

短辺取り装置８の可動側チャック８２は、図１６に示すように、シリンダ８３を伸長させると固定側チャック８１に近接し、シリンダ８３を縮小させると鎖線図示（符号８２′）するように固定側チャック８１から適宜距離（例えば１０〜１５cm程度）だけ離間するようになっている。又、可動側チャック８２による布片掴持力は、比較的ゆるいものであり、該可動側チャック８２で布片を掴持した状態で固定側チャック８１から離間方向に移動したときに、可動側チャック８２の掴持部分が布片に対して摺動するようになっている。   As shown in FIG. 16, the movable side chuck 82 of the short chamfering device 8 comes close to the fixed side chuck 81 when the cylinder 83 is extended, and is fixed as shown by a chain line (reference numeral 82 ') when the cylinder 83 is reduced. The side chuck 81 is appropriately separated by a distance (for example, about 10 to 15 cm). Further, the gripping force of the cloth piece by the movable side chuck 82 is relatively loose. When the cloth piece is gripped by the movable side chuck 82 and moved in the separating direction from the fixed side chuck 81, A gripping portion of the chuck 82 slides on the cloth piece.

各チャック８１，８２及びシリンダ８３は、取付台８４に対して軸棒を中心に回転可能に取付けられており、シリンダ８３で軸棒を回転させることにより、各チャック８１，８２を図１４〜図１６に示す上向き姿勢と図１７及び図１８に示す横向き（左向き）姿勢との角度９０°の範囲で変位させ得るようになっている。   The chucks 81 and 82 and the cylinder 83 are attached to the mounting base 84 so as to be rotatable about the shaft rod. By rotating the shaft rod with the cylinder 83, the chucks 81 and 82 are shown in FIGS. 16 and a lateral (leftward) orientation shown in FIGS. 17 and 18 can be displaced within an angle range of 90 °.

この短辺取り装置８は、次のように作動する。まず、布片短辺受け取り前は、図１４に示すように各チャック８１，８２が近接状態で且つ上向き姿勢で、右移動した位置での吸着ボックス６６′（図１４の鎖線図示位置）の右側面で展張されている布片下辺部Ｙａの直下位置で待機している。そして、ボックス右側面で布片Ｙの下部側が展張・保持された吸着ボックス６６が右移動した後（図１４に鎖線図示する符号６６′の状態）、図１５に示すように短辺取り装置８のモータ８６が上動側に作動して、両チャック８１，８２により凹部６８部分で展張している布片下辺部（布片短辺Ｙａ）を掴持する。このとき、固定側チャック８１は、布片短辺Ｙａの後側角端側に寄った位置を掴持している。その後、吸着ボックス６６側の両押え板７０，７０が符号７０′，７０′で示すように水平姿勢まで開放し、続いて吸着ボックス６６が図１５に鎖線図示する元の位置まで後退する。この状態では、図１６に示すように２つのチャック８１，８２が近接した状態で布片Ｙの短辺Ｙａを比較的狭い範囲で掴持している。続いて、シリンダ８３が縮小して可動側チャック８２を鎖線図示（符号８２′）する位置まで後退させ、そのとき可動側チャック８２の掴持部分が布片に摺動して、布片短辺を符号Ｙａ′で示すように所定長さだけ直線状に展張させるようになる。   The short chamfering device 8 operates as follows. First, before receiving the short side of the cloth piece, as shown in FIG. 14, the right side of the suction box 66 '(the position indicated by the chain line in FIG. 14) at the position where the chucks 81 and 82 are moved to the right in the proximity state and the upward posture. It waits in the position right under the cloth piece lower side part Ya extended by the surface. Then, after the suction box 66 in which the lower side of the cloth piece Y is stretched and held on the right side of the box is moved to the right (state of reference numeral 66 'shown by a chain line in FIG. 14), as shown in FIG. The motor 86 is moved upward to grip the lower part of the cloth piece (short piece Ya of the cloth piece) that is stretched at the concave portion 68 by the chucks 81 and 82. At this time, the fixed side chuck 81 holds a position close to the rear side corner end side of the cloth short side Ya. Thereafter, the presser plates 70 and 70 on the suction box 66 side are opened to the horizontal position as indicated by reference numerals 70 'and 70', and then the suction box 66 is retracted to the original position shown by the chain line in FIG. In this state, as shown in FIG. 16, the short side Ya of the cloth piece Y is gripped in a relatively narrow range with the two chucks 81 and 82 being close to each other. Subsequently, the cylinder 83 is reduced and the movable side chuck 82 is retracted to a position indicated by a chain line (reference numeral 82 '). At that time, the gripping portion of the movable side chuck 82 slides on the cloth piece, and the short side of the cloth piece. Is expanded linearly by a predetermined length as indicated by reference numeral Ya ′.

ところで、図１６に示すように両チャック８１，８２が上向き状態では、布片Ｙの大部分が下方に垂れ下がっていて、両チャック８１，８２′間で保持している布片短辺Ｙａ′が下向きになっている。従って、該布片短辺Ｙａ′を後述の長辺出し装置９のチャック９１で掴持することが困難となる。   Incidentally, as shown in FIG. 16, when both chucks 81 and 82 are in the upward state, most of the cloth piece Y hangs down, and the cloth piece short side Ya ′ held between the chucks 81 and 82 ′ It is facing down. Therefore, it becomes difficult to grip the short side Ya ′ of the cloth piece with the chuck 91 of the long side take-out device 9 described later.

そして、姿勢変更装置（シリンダ）８５により、上向き姿勢にある両チャック８１，８２′（図１６の状態）を図１７に示すように横向き（左向き）姿勢に変更する。この図１７の状態では、布片短辺Ｙａは各チャック８１，８２による掴持深さ部分で若干横向きになっているが、該短辺Ｙａ部分は概ね上向きになっていて、該短辺Ｙａ部分を後述する長辺出し装置９のチャック９１で上方から受け取り得るようになる。   Then, the posture changing device (cylinder) 85 changes both chucks 81 and 82 ′ (state shown in FIG. 16) in the upward posture to a horizontal (leftward) posture as shown in FIG. 17. In the state of FIG. 17, the short side Ya of the cloth piece is slightly lateral at the gripping depth portion by the chucks 81 and 82, but the short side Ya portion is generally upward, and the short side Ya The portion can be received from above by the chuck 91 of the long edge extracting device 9 described later.

長辺出し装置９は、図１７〜図１８に示すように、短辺取り装置８の両チャック８１，８２間に保持されている布片上辺部（短辺Ｙａ）を受け取るチャック９１と、該チャック９１を左右方向に移動させる左右動装置（モータ９２及び索９３）と、チャック９１で右方向に横引きされる布片Ｙを載せる載せ台９４とを有している。   As shown in FIGS. 17 to 18, the long edge take-out device 9 includes a chuck 91 that receives the upper side portion (short side Ya) of the cloth piece held between the chucks 81 and 82 of the short chamfering device 8, and It has a left-right movement device (motor 92 and cable 93) that moves the chuck 91 in the left-right direction, and a mounting table 94 on which the cloth piece Y that is horizontally pulled by the chuck 91 is placed.

長辺出し装置９のチャック９１は、前後方向にやや長い掴持部を有している。このチャック９１は、短辺取り装置８の両チャック８１，８２の直上方の待機位置から、載せ台９４の右側端部の直上方付近までの範囲で左右に移動される。   The chuck 91 of the long edge extracting device 9 has a grip portion that is slightly long in the front-rear direction. The chuck 91 is moved to the left and right in a range from a standby position immediately above both chucks 81 and 82 of the short chamfering device 8 to a position immediately above the right end portion of the mounting table 94.

載せ台９４は、チャック９１の移動高さよりやや低位置において後側側縁がチャック９１の移動位置のほぼ直下に位置するように設置されている。載せ台９４の右端寄りの後側側縁には左右に小間隔をもって３つの切欠溝９５，９５，９５が形成されている。この各切欠溝９５，９５，９５には、後述する載せ掛け装置１０の３つのチャック１０１，１０１，１０１の各掴持部が進入する（図２０）。   The mounting table 94 is installed such that the rear side edge is located almost immediately below the moving position of the chuck 91 at a position slightly lower than the moving height of the chuck 91. Three cutout grooves 95, 95, 95 are formed on the rear side edge near the right end of the mounting base 94 with a small left and right spacing. The gripping portions of three chucks 101, 101, 101 of the mounting device 10 described later enter the cutout grooves 95, 95, 95 (FIG. 20).

そして、この長辺出し装置９は、次のように作動する。まず、図１７の状態から短辺取り装置８の各チャック８１，８２が上動したときに、該各チャック８１，８２間に保持されている布片上辺部（短辺Ｙａ）を長辺出し装置９のチャック９１で受け取り（図１８の状態）、その後、モータ９２が右移動方向に作動してチャック９１で保持している布片上辺部（短辺Ｙａ）を右側に横引きして布片垂れ下げ部分を載せ台９４上に引き摺る。このように、布片上辺部（短辺Ｙａ）を保持して布片垂れ下げ部分を載せ台９４上に引き摺ると、図１８の符号Ｙ′で示すように布片垂れ下げ部分が長辺側に展張されながら載せ台９４上に載せられる。そして、該チャック９１が図１８の符号９１′で示す終端部まで移動した後に該チャックを開放して、布片Ｙを載せ台９４上に横たわらせる（図１９の状態となる）。この状態（図１９）では、載せ台９４上に載せられた布片Ｙの後側長辺Ｙｂがほぼ直線状に縁出しされるとともに、該後側長辺Ｙｂの右側端部寄り部分が載せ台９４の各切欠溝９５，９５，９５上に乗り上げている。   The long edge extracting device 9 operates as follows. First, when the chucks 81 and 82 of the short chamfering device 8 are moved up from the state shown in FIG. 17, the upper side of the cloth piece (short side Ya) held between the chucks 81 and 82 is extracted from the long side. The sheet is received by the chuck 91 of the apparatus 9 (the state shown in FIG. 18). Thereafter, the motor 92 operates in the right movement direction, and the cloth upper side portion (short side Ya) held by the chuck 91 is laterally pulled to the right. The one hanging part is dragged onto the mounting table 94. As described above, when the upper part of the cloth piece (short side Ya) is held and the cloth piece hanging part is dragged onto the mounting table 94, the cloth piece hanging part is moved to the long side as shown by reference numeral Y 'in FIG. It is placed on the mounting table 94 while being extended. Then, after the chuck 91 has moved to the end portion indicated by reference numeral 91 ′ in FIG. 18, the chuck is released and the cloth piece Y lies on the mounting table 94 (the state shown in FIG. 19 is reached). In this state (FIG. 19), the rear long side Yb of the cloth piece Y placed on the platform 94 is substantially linearly bordered, and the portion near the right end of the rear long side Yb is placed. It rides on the notch grooves 95, 95, 95 of the base 94.

載せ台９４上に載せられた布片Ｙ（後側長辺Ｙｂが縁出しされている）は、載せ掛け装置１０によって後述する姿勢補正装置１１上に載せ掛けられる。この載せ掛け装置１０は、載せ台９４の３つの切欠溝９５，９５，９５にそれぞれ進入し得る掴持部を持つ３つのチャック１０１，１０１，１０１と、該各チャック１０１，１０１，１０１を前後方向に進退させる前後動装置（モータ１０２及び索１０３）とを有している。そして、この載せ掛け装置１０は、図２０に示すように各チャック１０１，１０１，１０１を、前後動装置（モータ１０２及び索１０３）により載せ台９４上にある布片Ｙの長辺Ｙｂを掴持する前方位置と、該布片長辺Ｙｂを掴持して布片を後述の姿勢補正装置１１上に載せ掛け得る後方位置との間で進退させ得るようになっている。   The cloth piece Y (the rear long side Yb is bordered) placed on the platform 94 is placed on a posture correction device 11 described later by the placement device 10. The mounting device 10 includes three chucks 101, 101, 101 having gripping portions that can enter the three notch grooves 95, 95, 95 of the mounting table 94, and the chucks 101, 101, 101 in the front-rear direction. It has a back-and-forth motion device (motor 102 and cord 103) that moves back and forth in the direction. As shown in FIG. 20, the placing device 10 grips each chuck 101, 101, 101 by the longitudinal movement device (the motor 102 and the rope 103) and holds the long side Yb of the cloth piece Y on the placing table 94. It can be moved forward and backward between the forward position to hold and the rear position where the cloth piece long side Yb can be gripped and the cloth piece can be placed on the posture correcting device 11 described later.

布片Ｙを載せ掛ける姿勢補正装置１１は、図１９及び図２０に示すように、前後２つに分割された載せ掛けベルト１１１，１１１を有し、該各載せ掛けベルト１１１，１１を載せ台９４の各切欠溝９５，９５，９５を形成した部分の直下位置から後側に向けて前後方向に近接させた状態で設置している。各載せ掛けベルト１１１，１１１は、上面が左右方向に短い長さで、図２１に示すように該各ベルト上面の左右に布片Ｙを垂れ下げた状態で載せ得るようになっている。又、この各載せ掛けベルト１１１，１１１は、個別のモータ１１２，１１２でそれぞれ個別に作動せしめられる。   As shown in FIGS. 19 and 20, the posture correcting device 11 for placing the cloth piece Y has the placing belts 111 and 111 divided into two in the front and the back, and each of the placing belts 111 and 11 is placed on the platform. It is installed in a state of being close in the front-rear direction from the position directly below the portion where the 94 notch grooves 95, 95, 95 are formed. Each of the hanging belts 111 and 111 has a short top surface in the left-right direction, and can be placed in a state where the cloth piece Y is hung down on the left and right of the top surface of each belt as shown in FIG. Each of the belts 111 and 111 is individually operated by individual motors 112 and 112, respectively.
