Description

本願発明は、シーツのような大面積の布類を展張させて次工程側に搬送させるための布類展張搬送方法及び布類展張搬送機に関するものである。   The present invention relates to a cloth spreading and conveying method and a cloth spreading and conveying machine for spreading a cloth having a large area such as a sheet and conveying it to the next process side.

例えば、ランドリー工場においては、シーツのような大面積の布類を洗濯・乾燥後にプレス機でプレスしたり、折畳み機で折畳む作業が行われるが、その次工程装置（以下、プレス機で説明する）に布類を供給する際には、予め布類をきれいに展張させておく必要がある。   For example, in a laundry factory, a large area of cloth such as a sheet is washed and dried and then pressed with a press machine or folded with a folding machine. When the fabric is supplied to the fabric, it is necessary to preliminarily spread the fabric.

ところで、シーツのような大面積の布類を展張させて後送するための布類展張搬送機として、従来から図５及び図６に示すようなものがある。尚、この種の布類展張搬送機としては、例えば特開２００１−１５９０６７号公報（特許文献１）に示されるもののほか、多数公知になっている。   By the way, as shown in FIG. 5 and FIG. 6, conventionally, there are cloth spreading / conveying machines for spreading a large-area cloth such as a sheet and feeding it later. In addition, as this kind of cloth spreading and conveying machine, there are many well-known ones other than those disclosed in, for example, Japanese Patent Application Laid-Open No. 2001-159067 (Patent Document 1).

この図５及び図６に示す従来の布類展張搬送機は、大面積の布類Ｓの一辺（主として長辺）の両端角部Ｓａ，Ｓａを一対の投入チャック１１，１１で保持して所定高位置まで移送する投入装置１Ａ〜１Ｄと、投入装置１Ａ〜１Ｄによってそれぞれ高位置まで移送された布類Ｓ1の両端角部Ｓａ，Ｓａを左右２つの受取チャック２１Ａ，２１Ｂで受取って左右方向に展張させる左右展張装置２と、左右展張装置２の直下方に設置されていて左右展張装置２で展張された布類Ｓ2の下方部を吸引して展張させる吸引装置３と、左右展張装置２及び吸引装置３で展張された布類Ｓ4を受渡す受渡し装置４と、受渡し装置４から布類Ｓ5を受取ってプレス機側に搬送する搬送装置５とを備えている。 5 and 6, the conventional cloth spreading and conveying machine holds both end corners Sa and Sa of one side (mainly the long side) of the large-sized cloth S with a pair of input chucks 11 and 11. a feeding device 1A~1D for transferring to a high position, the left-right direction received respectively by the dosing device 1A~1D transported to the high position the cloth S 1 across corners Sa, the Sa two left and right receiving chucks 21A, at 21B the left and right stretched apparatus 2 to be stretched, the suction device 3 to stretched by sucking the lower portion of the stretched been cloth S 2 at the right and left stretched device 2 is placed right under the right and left deployed device 2, the right and left stretched device 2 and the suction device cloths S 4 delivery to transfer unit 4 that is deployed in three, and a transport device 5 which transports the press machine side from the transfer device 4 receives the cloth S 5.

この種の布類展張搬送機においては、各投入装置（１Ａ〜１Ｄ）の投入チャック１１，１１に保持された布類Ｓが上動・左右展張後、受渡し装置４に受け渡されるまでは比較的短時間（約６秒前後）で行われる一方、丸めた状態の布類から一辺の両端角部Ｓａ，Ｓａを捜し出してその両端角部Ｓａ，Ｓａを各投入チャック１１，１１に保持させる作業にはかなりの時間を要する（１枚当たり平均して１２〜１３秒かかる）。そして、この種の布類展張搬送機では、機械を効率よく作動させるために、１台の展張搬送機に複数基の投入装置を設置することが多く、図５の従来例のものでは投入装置を左右に４基（１Ａ〜１Ｄ）設置している。尚、４基の投入装置１Ａ〜１Ｄを設置して全投入装置から布類投入作業を行う場合には、１枚当たりの布類投入時間が３秒程度（１２秒÷４）で行え、布類投入能力にはかなりの余裕がある（各投入装置１Ａ〜１Ｄにおいてはそれぞれかなりの待ち時間ができる）。   In this type of cloth spreading and conveying machine, comparison is made until the cloth S held by the feeding chucks 11 and 11 of each feeding device (1A to 1D) is moved up and left and right and then delivered to the delivery device 4. It is performed in a short time (about 6 seconds), while the corners Sa and Sa on one side are searched from the cloth in a rolled state and the corners Sa and Sa are held by the input chucks 11 and 11. Takes a considerable amount of time (on average 12-13 seconds per sheet). In order to operate the machine efficiently in this type of fabric stretcher, a plurality of feeders are often installed in one stretcher, and in the conventional example of FIG. Are installed on the left and right (1A-1D). In addition, when four cloth making devices 1A to 1D are installed and cloth making work is performed from all the making devices, the cloth making time per sheet can be about 3 seconds (12 seconds ÷ 4). There is a considerable allowance in the kind throwing capacity (the waiting time can be considerable in each of the throwing apparatuses 1A to 1D).

又、この各投入装置１Ａ〜１Ｄ間には、それぞれ作業スペースを確保する必要からかなりの間隔（隣接する投入装置の各中心間隔が例えば１.５〜１.６ｍ程度）を有しており、左端の投入装置１Ａの中心から右端の投入装置１Ｄの中心までの間隔が例えば４.５〜４.８ｍ程度ある。   In addition, there is a considerable space between each of the charging devices 1A to 1D because it is necessary to secure a working space (the center distance between adjacent charging devices is, for example, about 1.5 to 1.6 m). The distance from the center of the leftmost charging device 1A to the center of the rightmost charging device 1D is, for example, about 4.5 to 4.8 m.

この各投入装置１Ａ〜１Ｄは、左右の各投入チャック１１，１１で布類Ｓの一辺（長辺）の両端角部Ｓａ，Ｓａをそれぞれ保持した状態で、該各投入チャック１１，１１を昇降装置（ロッドレスシリンダ）１２により上方に移動させるようになっている。尚、この各投入装置１Ａ〜１Ｄ部分では、投入チャック１１，１１に布類の両端角部Ｓａ，Ｓａを保持させた後、それぞれスタートボタン（１３Ａ〜１３Ｄ）を押すが、スタートボタンを押した順番は順次コントローラに記憶される。   Each of the charging devices 1A to 1D moves up and down each of the charging chucks 11 and 11 with the left and right charging chucks 11 and 11 holding the corners Sa and Sa on one side (long side) of the cloth S, respectively. The device (rodless cylinder) 12 is moved upward. In each of the charging devices 1A to 1D, after the holding chucks 11 and 11 hold the corners Sa and Sa of the cloth, the start button (13A to 13D) is pressed, but the start button is pressed. The order is sequentially stored in the controller.

左右展張装置２は、各投入チャック１１，１１で保持されている布類両端角部Ｓａ，Ｓａを受取る左右一対の受取チャック２１Ａ，２１Ｂを有している。この各受取チャック２１Ａ，２１Ｂは、布類の両端角部Ｓａ，Ｓａを保持した状態で、それぞれ左右動装置（サーボモータ２３Ａ，２３Ｂを有する）２２Ａ，２２Ｂにより相互に離間・近接方向に作動せしめられる。そして、各受取チャック２１Ａ，２１Ｂを図５に符号２１Ａ′，２１Ｂ′で示す位置（布類Ｓ2の上辺部が緊張する位置）まで離間させることにより、該布類上辺部を展張機の中央部においてきれいに展張させ得るようになっている。 The left and right extension device 2 has a pair of left and right receiving chucks 21A and 21B that receive the cloth both ends corner portions Sa and Sa held by the respective input chucks 11 and 11. The receiving chucks 21A and 21B are operated in the direction of separation and proximity to each other by the left and right movement devices (having servo motors 23A and 23B) 22A and 22B while holding the both end corners Sa and Sa of the cloth. It is done. Each receive chucks 21A, 21B code 21A in FIG. 5 a ', 21B' by spaced to the position indicated by (a position where the upper side portion of the cloth S 2 is tense), central stretched machine cloth such upper portion It can be made to spread neatly in the department.

吸引装置３は、図６に示すように縦向きの吸引ボックス３１内の空気を吸引機（バキュームファン）３３で下方に吸引するようになっている。吸引ボックス３１の吸気口３２の近傍には、モータ３８，３８（図５）よって回転せしめられる送込みローラ３７，３７が設けられている。   As shown in FIG. 6, the suction device 3 sucks the air in the vertical suction box 31 downward by a suction machine (vacuum fan) 33. In the vicinity of the suction port 32 of the suction box 31, feed rollers 37, 37 that are rotated by motors 38, 38 (FIG. 5) are provided.

受渡し装置４は、吸着ボックス４１を伸縮シリンダ４３で前後移動させ得るようにしたものである。   The delivery device 4 is configured such that the suction box 41 can be moved back and forth by the telescopic cylinder 43.

搬送装置５は、左右展張装置２から受渡し装置４を介して展張状態の布類Ｓ4を受取る前側コンベア（バキュームコンベア）５１と、それに連続する後側コンベア（排出コンベア）５２を有している。尚、後側コンベア５２は、プレス機側に連続している。 Conveying device 5 includes a front conveyor (Vacuum conveyor) 51 which receives the cloth S 4 of stretched state from the lateral stretched apparatus 2 via the transfer device 4, a side conveyor (delivery conveyor) 52 after successive thereto . The rear conveyor 52 is continuous with the press side.

図５及び図６の布類展張搬送機は、次のように機能する。まず、各投入装置１Ａ〜１Ｄのそれぞれ作業位置において洗濯・乾燥済みの大面積布類Ｓから一辺（長辺）の両端角部Ｓａ，Ｓａを捜し出して当該投入装置（１Ａ〜１Ｄ）の各投入チャック１１，１１に保持させた後、当該投入装置のスタートボタン（１３Ａ〜１３Ｄ）を押すが、そのスタートボタン操作順は順次コントローラ（図示しない）に記憶される。そして、左右展張装置２の各左右動装置２２Ａ，２２Ｂにより各受取チャック２１Ａ，２１Ｂを、先順の投入装置（図５の状態では左から２番目の投入装置１Ｂ）の各投入チャック１１，１１に対応する位置までそれぞれ移動させ、その後に各投入チャック１１，１１が布類両端角部Ｓａ，Ｓａを保持したまま上動して、その布類両端角部を各受取チャック２１Ａ，２１Ｂに受渡し（Ｓ1の状態）、次に該各受取チャック２１Ａ，２１Ｂがそれぞれ左右外側に移動して（符号２１Ａ′，２１Ｂ′の各位置）、布類Ｓ1の上辺部を展張させる（Ｓ2の状態）。続いて、送込みローラ３７が送込み方向に高速回転するとともに、切換ダンパ３５が鎖線図示側に切換えられて吸引ボックス３１内の空気が吸引され、布類の下端側がＳ3の状態を経てＳ4のように吸引ボックス３１内に吸い込まれる。このとき、この布類には、バキュームファン３３の吸引作用により下方へのテンションがかけられて、該布類が方形状に展張される（Ｓ4の状態）。その後、切換ダンパ３５が実線図示側に切換えられ、各受取チャック２１Ａ′，２１Ｂ′で保持されていた布類Ｓ4の上辺部が吸着ボックス４１の先端側上面に吸着・保持され、該吸着ボックス４１が鎖線図示するように後退し、そのとき布類上辺部が前側コンベア（バキュームコンベア）５１上に移乗され（符号Ｓ5の状態）、布類が展張状態のままで前側コンベア５１及び後側コンベア５２を経てプレス機側に供給される。 The cloth spreading and conveying machine of FIGS. 5 and 6 functions as follows. First, each corner (Sa, Sa) of one side (long side) is searched from the large-sized cloth S that has been washed and dried at the working position of each of the loading devices 1A to 1D, and each loading device (1A to 1D) is loaded. After being held by the chucks 11, 11, the start button (13 </ b> A to 13 </ b> D) of the input device is pushed, but the start button operation order is sequentially stored in a controller (not shown). Then, the receiving chucks 21A and 21B are moved by the left and right moving devices 22A and 22B of the left and right extension device 2, and the loading chucks 11 and 11 of the first loading device (second loading device 1B from the left in the state of FIG. 5). Are moved to positions corresponding to each of the chucks, and thereafter, the respective input chucks 11 and 11 are moved upward while holding the cloth both end corners Sa and Sa, and the cloth both end corners are transferred to the receiving chucks 21A and 21B. (state of the S 1), then respective receiving chuck 21A, 21B is moved to the left and right outside areas (code 21A ', 21B' each position), it is stretched the upper side of the cloth S 1 of (S 2 Status). Subsequently, the high-speed rotation in the direction infeed roller 37 infeed, switch damper 35 is switched to the chain line shown side air in the suction box 31 is sucked, the lower end of the cloth is via the state of S 3 S 4 is sucked into the suction box 31. In this case, this cloth, are putting tension downward by the suction action of the vacuum fan 33, the fabric such is deployed in a square shape (the S 4 state). Then, switching damper 35 is switched to the solid line shown side, each recipient chucks 21A ', 21B' upper side portion of the cloth S 4 which has been held in are adsorbed and held on the front end side upper surface of the suction box 41, adsorption box 41 moves backward as shown by the chain line, and at that time, the upper side of the cloth is transferred onto the front conveyor (vacuum conveyor) 51 (in the state of S 5 ), and the front conveyor 51 and the rear side are left in the stretched state. It is supplied to the press side through the conveyor 52.

各受取チャック２１Ａ′，２１Ｂ′は、布類角部の保持を開放した後、それぞれ左右動装置２２Ａ，２２Ｂ（サーボモータ２３Ａ，２３Ｂ）により、スタートボタンが押された次順の投入装置の各投入チャック１１，１１（布類両端角部を保持して待機している）に対応する位置まで移動された後、当該投入装置が作動して次の布類Ｓの両端角部Ｓａ，Ｓａを各受取チャック２１Ａ，２１Ｂに受け渡し、以下同様に上記動作を行って搬送装置５側に移送される。   The receiving chucks 21A 'and 21B' release the holding of the cloth corners, and then the left and right moving devices 22A and 22B (servo motors 23A and 23B) respectively, After being moved to a position corresponding to the input chucks 11 and 11 (holding both ends corners of the cloth and waiting), the input device is operated and both end corners Sa and Sa of the next cloth S are moved. The paper is delivered to each of the receiving chucks 21A and 21B, and subsequently transferred to the conveying device 5 side by performing the above operation in the same manner.

ところで、各左右動装置２２Ａ，２２Ｂによる各受取チャック２１Ａ，２１Ｂの移動スピードは、布類展張時が７０ｍ／分程度（秒速約１.２ｍ）であり、空状態での移動時が２６０ｍ／分程度（秒速約４.３ｍ）である。他方、展張処理される布類Ｓは、サイズにもよるが長辺側の長さが約３ｍ程度あり、図５に符号Ｓ2で示す布類の展張状態では、左側受取チャック２１Ａ′の位置Ａ0及び右側受取チャック２１Ｂ′の位置Ｂ0が機体１０の中央から左右にそれぞれ約１.５ｍ程度離れた位置にある。 By the way, the moving speed of the receiving chucks 21A and 21B by the left and right moving devices 22A and 22B is about 70 m / min when the fabric is stretched (about 1.2 m per second), and 260 m / min when moving in the empty state. Is about 4.3 m / s. On the other hand, the fabric S to be stretched has a length of about 3 m on the long side depending on the size. In the fabric stretched state indicated by S 2 in FIG. 5, the position of the left receiving chuck 21A ′ The position A 0 and the position B 0 of the right receiving chuck 21B ′ are located at a distance of about 1.5 m from the center of the machine body 10 to the left and right.

そして、この各受取チャック２１Ａ′，２１Ｂ′は、布類展張位置において布類各端部を開放した後、それぞれ次順の投入装置の各投入チャック１１，１１に対応する位置まで移動せしめられるが、そのとき次順の投入装置が左右各端部のもの（１Ａ又は１Ｄ）である場合には、左右の受取チャック２１Ａ′，２１Ｂ′の一方をかなり長い距離移動させる必要がある。即ち、次順の投入装置が、図５において例えば左端部の投入装置１Ａである場合には、左側受取チャック２１Ａ′は左側展開位置Ａ0から左端部の投入装置１Ａの左側投入チャック１１に対応する位置Ａ1までの比較的短い距離Ｌ1（例えば０.４〜０.５ｍ程度）を移動させればよいが、右側受取チャック２１Ｂ′は右側展開位置Ｂ0から当該投入装置１Ａの右側投入チャック１１に対応する位置Ｂ1までのかなり長い距離Ｌ2（３ｍ前後）を移動させる必要があり、該右側受取チャック２１Ｂ′が該距離Ｌ2（３ｍ前後）を移動するのに単純計算で約０.７秒かかる。 Each of the receiving chucks 21A 'and 21B' is moved to a position corresponding to each of the input chucks 11 and 11 of the next input device after the respective ends of the fabric are opened at the cloth extension position. In this case, when the next order insertion device is one at the left and right ends (1A or 1D), it is necessary to move one of the left and right receiving chucks 21A 'and 21B' by a considerably long distance. That is, the next order of the dosing device, when a dosing device 1A, for example the left end portion in FIG. 5, left side receives the chuck 21A 'corresponding from the left deployed position A 0 in the left-on chuck 11 of the input device 1A at the left end relatively short distance to a position a 1 to L 1 (for example, about 0.4～0.5M) may be moved, but the right receives the chuck 21B 'right-on from the right side deployed position B 0 of the dosing device 1A It is necessary to move a considerably long distance L 2 (about 3 m) to the position B 1 corresponding to the chuck 11, and the right receiving chuck 21 B ′ moves about the distance L 2 (about 3 m) by simple calculation. It takes 0.7 seconds.

特開２００１−１５９０６７号公報JP 2001-159067 A

ところで、図５及び図６に示す従来の布類展張搬送機では、受取チャック２１Ａ〜２１Ｂが２つ１組のみであるので、上記のように各外端部に位置する各投入装置１Ａ，１Ｄ部分の布類を展張・後送するのに約６秒かかる。他方、投入装置１Ａ〜１Ｄは４基有しているので、布類投入能力に十分余力があり（１枚当たりの布類投入時間は約３秒である）、各投入装置１Ａ〜１Ｄ部分ではそれぞれかなりの待ち時間が生じる。   Incidentally, in the conventional cloth spreading and conveying machine shown in FIGS. 5 and 6, since there are only two sets of receiving chucks 21A to 21B, each of the feeding devices 1A and 1D located at the outer end portions as described above. It takes about 6 seconds to spread and post the part of the fabric. On the other hand, since there are four throwing devices 1A to 1D, there is sufficient capacity for the cloth throwing capacity (the cloth throwing time per sheet is about 3 seconds), and in each throwing device 1A to 1D, Each has considerable latency.

このように、従来の布類展張搬送機では、各投入装置側での布類投入能力に十分余力があるにも拘わらず、特に左右各端部に位置する投入装置１Ａ，１Ｄの布類を処理するのに受取チャック（２１Ａ又は２１Ｂ）の移動距離（及び移動時間）が長いために、１枚当たりの布類処理スピードを速くできない（時間当たりの布類処理枚数が少ない）という問題があった。   As described above, in the conventional cloth spreading / conveying machine, the cloths of the feeding devices 1A and 1D positioned at the left and right end portions are used even though the cloth feeding capacity on each feeding device side has a sufficient margin. Since the moving distance (and moving time) of the receiving chuck (21A or 21B) is long for processing, there is a problem that the cloth processing speed per sheet cannot be increased (the number of cloth processed per hour is small). It was.

そこで、本願発明は、受取チャック側での布類処理スピードを速くして、時間当たりの布類処理枚数を多くできるようにした布類展張搬送方法及び布類展張搬送機を提供することを目的としている。   SUMMARY OF THE INVENTION An object of the present invention is to provide a cloth spreading / conveying method and a cloth spreading / conveying machine capable of increasing the number of cloths processed per hour by increasing the cloth processing speed on the receiving chuck side. It is said.

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、洗濯・乾燥後のシーツのような大面積布類をきれいに展張して後送させるための布類展張搬送方法を対象にしている。 [Invention of Claim 1 of the Present Application]
The invention of claim 1 of the present application is directed to a cloth spreading / conveying method for neatly spreading a large-area cloth such as a sheet after washing and drying and feeding it backward.

この請求項１の布類展張搬送方法は、機体の前部において左右一対の投入チャックを有した投入装置によりシーツのような大面積の布類の一辺の両端角部を保持して所定高位置まで吊上げ、その吊上げ布類の各保持部分を左右展張装置の２つの受取チャックで受取り、該両受取チャックを左右に離間させて吊上げ布類を左右に展張させた後、その展張布類を次工程側に搬送させるようにしたものである。   According to the cloth extending and conveying method of the first aspect of the present invention, the corners of one side of a large-sized cloth such as a sheet are held at a predetermined high position by a feeding device having a pair of left and right feeding chucks at the front of the machine body. And lift each of the holding parts of the lifted cloth with the two receiving chucks of the right and left spreading device, and separate the receiving chucks to the left and right to extend the lifting cloth to the left and right. It is made to convey to the process side.

又、この布類展張搬送方法では、投入装置は左右に複数基設置し、左右展張装置は１つの受取チャックと該受取チャックを左右に移動させる１つの左右動装置を１セットにした展開チャック装置を３セット使用し、さらに各展開チャック装置の３つの受取チャックが左右同一直線上に位置するように配置したものを使用している。   Further, in this cloth spreading and conveying method, a plurality of feeding devices are installed on the left and right, and the right and left spreading device is a developing chuck device in which one receiving chuck and one left and right moving device for moving the receiving chuck to the left and right are set as one set. 3 sets are used, and further, three receiving chucks of each developing chuck device are arranged so that they are positioned on the same straight line on the left and right.

投入装置は、左右に複数基設置されているが、２基では左右展張装置側での処理能力が布類投入能力を上回ることがあるので処理能力に無駄ができることがあり、他方、５基以上では左右展張装置側での処理能力に対して布類投入能力が必要以上に上回るので設備（投入装置）に無駄ができるとともに機体が必要以上に大型化する。従って、この投入装置は、実際には３基又は４基が好ましい。   There are a plurality of input devices installed on the left and right, but with two units, the processing capacity on the left and right extension device side may exceed the cloth input capacity, so the processing capacity may be wasted. Then, since the cloth input capacity exceeds the processing capacity on the left and right extension device side more than necessary, the equipment (input device) can be wasted and the machine body becomes larger than necessary. Therefore, in reality, three or four charging devices are preferable.

この投入装置には、人の肩幅程度の間隔をもって左右一対の投入チャックが設けられているとともに、該各投入チャックを昇降装置により所定高さ範囲で昇降させ得るようになっている。又、各投入装置部分にはそれぞれ作業スペースを確保する必要から、各投入装置間にかなりの間隔（隣接する投入装置の各中心間隔が例えば１.５〜１.６ｍ程度）を有しており、４基の投入装置を使用したものでは両端に位置する２つの投入装置の中心間隔が例えば４.５〜４.８ｍ程度になっている。   The loading device is provided with a pair of left and right loading chucks at intervals of about the width of a person's shoulder, and each loading chuck can be lifted and lowered within a predetermined height range by a lifting device. In addition, since it is necessary to secure a working space for each charging device, there is a considerable space between the charging devices (center distance between adjacent charging devices is about 1.5 to 1.6 m, for example). In the case of using four charging devices, the center distance between the two charging devices located at both ends is, for example, about 4.5 to 4.8 m.

この各投入装置は、両投入チャックに布類の一辺の両端角部を保持させた後、スタートボタンを押すと、コントローラに作動順が記憶されて待機するようになっている。そして、作動順が到来した投入装置に対して左右展張装置の受取チャックが受取り可能位置まで移動した時点で、待機していた当該投入装置が作動するようになっている。尚、各投入装置の作動順は、それぞれ作業員が布類の一辺（長辺）の両端角部を捜し出して、該両端角部をそれぞれ投入チャックに保持させた後、スタートボタンを押すと、そのスタートボタン操作順がコントローラに記憶されて、各投入装置の作動順が決められる。   Each throwing device holds the both corners of one side of the cloth on both throwing chucks and then presses the start button so that the operation order is stored in the controller and waits. Then, when the receiving chuck of the left and right extension device moves to the receivable position with respect to the input device that has arrived in the operating order, the input device that has been waiting is operated. In addition, the operating order of each charging device is that each worker searches for both corners of one side (long side) of the cloth, and holds both corners on the loading chuck, and then presses the start button. The start button operation order is stored in the controller, and the operation order of each input device is determined.

左右展張装置には、３セットの展開チャック装置が使用されているが、この各展開チャック装置の３つの受取チャックは所定高さ位置の左右同一直線上においてそれぞれ左右動装置で個別に左右移動せしめられるようになっている。   Three sets of unfolding chuck devices are used for the left-right stretching device. The three receiving chucks of each unfolding chuck device are individually moved left and right by the left-right motion device on the same straight line at the predetermined height position. It is supposed to be.

そして、この請求項１の布類展張搬送方法は、複数基の投入装置における作動順が到来した投入装置の各投入チャックに対応する位置に、３セットの展開チャック装置における中間受取チャックと作動順が到来した投入装置に近い位置にある左右いずれか１つの外側受取チャックとを移動させるようにしている。   In the cloth spreading and conveying method according to the first aspect, the intermediate receiving chucks in the three sets of unfolding chuck devices and the operation order are arranged at positions corresponding to the respective input chucks of the input device in which the operation order of the plurality of input devices has arrived. One of the left and right outer receiving chucks in the position close to the input device that has arrived is moved.

即ち、この布類展張搬送方法によれば、作動順が到来した投入装置が機体中央部から左側のものである場合には、左側受取チャックと中間受取チャックの２つを当該投入装置の各投入チャックに対応する位置まで移動させ、逆に作動順が到来した投入装置が機体中央部から右側のものである場合には、右側受取チャックと中間受取チャックの２つを当該投入装置の各投入チャックに対応する位置まで移動させるようにしている。又、投入装置が３基のものでは、中央に位置する中間投入装置に対して中間受取チャックと左右いずれか一方の外側受取チャックを移動させる。尚、各受取チャックの移動時には、使用しない１つの外側受取チャックは、布類展張作業の邪魔にならない左右外側の退避位置に移動させる。   That is, according to this cloth spreading and conveying method, when the input device that has arrived in the operation order is the one on the left side from the central part of the machine body, the left receiving chuck and the intermediate receiving chuck are connected to each of the input devices. When the input device that has been moved to the position corresponding to the chuck and the operation order has come to the right is from the center of the machine body, the right receiving chuck and the intermediate receiving chuck are connected to the respective input chucks of the input device. It is made to move to the position corresponding to. In the case of three feeding devices, the intermediate receiving chuck and one of the left and right outer receiving chucks are moved with respect to the intermediate charging device located at the center. When each receiving chuck is moved, one unused outer receiving chuck is moved to the left and right outer retracted positions that do not interfere with the cloth spreading operation.

このようにすると、作動順が到来した投入装置に対して、３つの受取チャックのうちの当該投入装置に近い２つの受取チャックが使用されるので、従来のように受取チャックが２つしかないものに比して、作動順が到来した投入装置に対して受取チャックの移動距離が短くなる場合がある。   In this case, since two receiving chucks that are close to the loading device among the three receiving chucks are used for the loading device in which the operation order has arrived, there are only two receiving chucks as in the prior art. As compared with the case, the moving distance of the receiving chuck may be shortened with respect to the charging device in which the operation order has arrived.

即ち、４基の投入装置を使用している場合、例えば左側受取チャックと中間受取チャックとが布類展張位置にある状態で、次順の投入装置が左端部のものである場合には、右展張位置にある中間受取チャックが左端投入装置の右側投入チャックの位置まで移動する必要から、該受取チャックの移動距離の短縮は起きないが、その状態で次順の投入装置が機体中央部から右側に位置するものである場合には、当該投入装置における左側投入チャックに対応する位置に中間受取チャックが移動し、右側投入チャックに対応する位置に右側受取チャックが移動するので、２つだけの受取チャックしかない従来のものに比して、受取チャックの移動距離が短縮できるようになる。   That is, when using four feeding devices, for example, when the left receiving chuck and the intermediate receiving chuck are in the cloth extending position and the next charging device is the one at the left end, Since the intermediate receiving chuck in the extended position needs to move to the position of the right side input chuck of the left end input device, the movement distance of the reception chuck does not occur, but in that state the next input device is the right side from the center of the machine body. The intermediate receiving chuck moves to a position corresponding to the left loading chuck in the loading apparatus, and the right receiving chuck moves to a position corresponding to the right loading chuck. The moving distance of the receiving chuck can be shortened as compared with the conventional one having only the chuck.

因に、上記した従来例（図５及び図６）のものでは、２つの受取チャックのみで行っていたので、受取チャックの移動距離が最大で３ｍでそのときの移動時間が約０.７秒かかっていたが、本願では、該受取チャックの移動距離が半分程度でよい場合が多くなる。   Incidentally, in the above-described conventional example (FIGS. 5 and 6), since only two receiving chucks are used, the moving distance of the receiving chuck is 3 m at the maximum, and the moving time at that time is about 0.7 seconds. However, in this application, there are many cases where the movement distance of the receiving chuck may be about half.

尚、受取チャックの移動距離が短縮できるのは、主として左右各端部に位置する投入装置１Ａ，１Ｄの布類を処理するときであるが、この左右各端部の投入装置の作動順は単純計算で２回に１回の割合で巡ってくる。   The movement distance of the receiving chuck can be shortened mainly when processing the cloths of the input devices 1A and 1D located at the left and right ends, but the operation order of the input devices at the left and right ends is simple. It goes around once every two times in the calculation.

ところで、作動順が到来した投入装置部分に受取チャックを移動させるときの移動距離を短くするのに、本願で使用している１セットの展開チャック装置（１つの受取チャックと１つの左右動装置）を左右に４セットして、その左右２セットずつでそれぞれ４基の投入装置の左右２基ずつを担当させるようにすることも考えられる。ところが、その場合（展開チャック装置が４セットの場合）には、本願の展開チャック装置が３セットのものと機能面（受取チャックの移動距離短縮）ではほとんど差がないにも拘わらず、展開チャック装置のセット数が単純に１セット多くなり、コスト面や設置スペースの面で不利になるという問題がある。   By the way, a set of unfolding chuck devices (one receiving chuck and one left-right moving device) used in the present application is used to shorten the moving distance when the receiving chuck is moved to the loading device portion where the operation order has arrived. It is also conceivable that four sets are set on the left and right, and two sets on the left and right are assigned to each of the left and right sets of four input devices. However, in that case (when there are four sets of deployment chuck devices), the deployment chuck device of the present application is almost the same as the three deployment chuck devices in terms of function (reduction of the moving distance of the receiving chuck). There is a problem that the number of sets of devices is simply increased by one, which is disadvantageous in terms of cost and installation space.

［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の布類展張搬送方法を行うための布類展張搬送機を対象にしている。即ち、この請求項２の布類展張搬送機は、機体の前部において左右一対の投入チャックを有した投入装置によりシーツのような大面積の布類の一辺の両端角部を保持して所定高位置まで吊上げ、その吊上げ布類の各保持部分を左右展張装置の２つの受取チャックで受取り、該両受取チャックを左右に離間させて吊上げ布類を左右に展張させた後、その展張布類を後送手段で次工程側に搬送させるようにしたものである。 [Invention of claim 2 of the present application]
The invention of claim 2 of the present application is directed to a cloth spreading and conveying machine for performing the cloth spreading and conveying method of claim 1 described above. That is, the cloth spreading and conveying machine according to the second aspect of the present invention holds the both end corners of one side of a large cloth such as a sheet by a feeding device having a pair of left and right feeding chucks at the front of the machine body. Lifting up to a high position, receiving each holding part of the lifting cloth with the two receiving chucks of the left and right extension devices, separating the receiving chucks to the left and right, and extending the lifting cloth to the left and right, and then the extending cloths Is conveyed to the next process side by the post-feed means.

そして、この請求項２の布類展張搬送機には、投入装置を左右に複数基（３基又は４基が好ましい）設置し、左右展張装置として１つの受取チャックと該受取チャックを左右に移動させる１つの左右動装置を１セットにした展開チャック装置を３セット使用し、各展開チャック装置の３つの受取チャックを左右同一直線上に位置するように配置しているとともに、複数基の投入装置における作動順が到来した投入装置の各投入チャックに対応する位置に、３セットの展開チャック装置における中間受取チャックと作動順が到来した投入装置に近い位置にある左右いずれか１つの外側受取チャックとを移動させるように制御するコントローラを備えている。   In the cloth spreading and conveying machine according to claim 2, a plurality of feeding devices (preferably three or four) are installed on the left and right, and one receiving chuck and the receiving chuck are moved left and right as the left and right stretching devices. Three sets of unfolding chuck devices with one set of left and right moving devices to be used are used, and three receiving chucks of each unfolding chuck device are arranged so as to be positioned on the same straight line on the left and right, and a plurality of charging devices The intermediate receiving chucks in the three sets of deployment chuck devices and any one of the left and right outer receiving chucks in a position close to the charging device in which the operating order has arrived A controller for controlling the movement of the robot.

この請求項２の布類展張搬送機では、上記各構成により、上記請求項１の布類展張搬送方法の場合と同じ機能を達成できる。   In the cloth spreading and conveying machine according to the second aspect, the same functions as those of the cloth extending and conveying method according to the first aspect can be achieved by the above-described configurations.

本願請求項１及び２の各発明では、複数基の投入装置と３セットの展開チャック装置とを有し、作動順が到来した投入装置に対して３つの受取チャックのうちの当該投入装置に近い２つの受取チャックを布類受取位置（投入装置の各投入チャックが対応する位置）まで移動させるようになっているので、受取チャックの移動距離を短くできる場合が多くなる。   Each of the inventions of claims 1 and 2 includes a plurality of input devices and three sets of deployment chuck devices, and is close to the input device of the three receiving chucks with respect to the input device whose operation order has arrived. Since the two receiving chucks are moved to the cloth receiving position (the position corresponding to each loading chuck of the loading device), the movement distance of the receiving chuck can often be shortened.

従って、本願各発明では、作動順が到来した投入装置に対して受取チャックを移動させる際に、全体として受取チャックの移動に要する時間が短くなるので、布類１枚当たりの処理時間が短縮され、時間当たり布類処理枚数を多くできるという効果がある。   Accordingly, in each invention of the present application, when the receiving chuck is moved with respect to the input device that has arrived in the order of operation, the time required for the movement of the receiving chuck as a whole is shortened, so the processing time per piece of fabric is shortened. There is an effect that the number of processed fabrics per hour can be increased.

又、処理しようとしている投入装置が左右いずれの位置のものでも、３つの展開チャック装置のうちの中間受取チャックを有した展開チャック装置は常に使用されるので、該中間受取チャックの展開チャック装置を常時共用（有効利用）できるという効果がある。   Moreover, since the developing chuck device having the intermediate receiving chuck among the three developing chuck devices is always used regardless of whether the input device to be processed is at the left or right position, the developing chuck device of the intermediate receiving chuck is used. There is an effect that it can always be shared (effectively used).

因に、上記したように、４セットの展開チャック装置を使用して、その左右２セットずつでそれぞれ４基の投入装置の左右２基ずつを担当させるようにすることも考えられるが、その場合（展開チャック装置が４セットの場合）には、本願の展開チャック装置が３セットのものと機能面（受取チャックの移動距離短縮）ではほとんど差がないにも拘わらず、展開チャック装置のセット数が単純に１セット多くなり、コスト面や設置スペースの面で不利になる。   In addition, as described above, it is conceivable to use four sets of deployment chuck devices, and each of the left and right sets of the four loading devices is in charge of two sets of left and right, respectively. (When there are 4 sets of deploying chuck devices), the number of deploying chuck devices is set in spite of the fact that there is almost no difference in the functional aspect (reduction of the moving distance of the receiving chuck) from the 3 deploying chuck devices of the present application. Is simply one set more, which is disadvantageous in terms of cost and installation space.

以下、図１〜図４を参照して本願実施例の布類展張搬送方法及び布類展張搬送機を説明する。尚、この実施例の布類展張搬送機は、シーツのような大面積の布類Ｓをきれいに展張させてプレス機や折畳み機のような次工程装置側に搬送するものである。   Hereinafter, the cloth spreading and conveying method and the cloth spreading and conveying machine according to the present embodiment will be described with reference to FIGS.

Yes, the explanation of the section of the prior art is used as the explanation of the structure, function, etc. of these devices except for those described below. The suction box 41 of the delivery device 4 has a large number of small holes on the upper surface of the front half, and the air in the suction box 41 is sucked by the suction machine 42 so that the suction box 41 has an upper surface on the upper surface of the front half. The upper side of the cloth can be adsorbed.

４基の各投入装置１Ａ〜１Ｄは、図５の従来例のものと同様に、機体１０の前部において左右に所定間隔をもって並置されていて、左端の投入装置１Ａの中心から右端の投入装置１Ｄの中心までの間隔が例えば４.５〜４.８ｍ程度有している。尚、以下の説明では、各投入装置１Ａ〜１Ｄを左側から順に、第１投入装置１Ａ、第２投入装置１Ｂ、第３投入装置１Ｃ、第４投入装置１Ｄということがある。   Each of the four throwing devices 1A to 1D is juxtaposed at a predetermined interval on the left and right at the front portion of the airframe 10 in the same manner as the conventional example in FIG. The distance to the center of 1D is, for example, about 4.5 to 4.8 m. In the following description, the charging devices 1A to 1D may be referred to as the first charging device 1A, the second charging device 1B, the third charging device 1C, and the fourth charging device 1D in order from the left side.

この各投入装置１Ａ〜１Ｄには、人の肩幅程度の間隔をもって左右一対の投入チャック１１，１１を有している。この各投入チャック１１，１１は、昇降装置１２により、作業員が布類両端角部Ｓａ，Ｓａを保持させ得る下動位置と、上方にある各受取チャック（２１Ａ〜２１Ｃ）に布類両端角部Ｓａ，Ｓａを受渡し得る上動位置との間で上下動せしめられる。   Each of the input devices 1A to 1D has a pair of left and right input chucks 11 and 11 with an interval about the width of a person's shoulder. Each of the input chucks 11 and 11 is moved downward by a lifting / lowering device 12 so that the worker can hold the cloth both end corners Sa and Sa, and each receiving chuck (21A to 21C) above has cloth both end angles. It can be moved up and down between the upper movement positions where the parts Sa and Sa can be delivered.

又、各投入装置１Ａ〜１Ｄには、それぞれスタートボタン１３Ａ〜１３Ｄが設けられている。そして、両投入チャック１１，１１に布類両端角部Ｓａ，Ｓａを保持させた後、当該投入装置１Ａ〜１Ｄのスタートボタン１３Ａ〜１３Ｄを押すと、その信号がコントローラ９に入力されて、投入装置の作動順が決められる。尚、スタートボタンを押した各投入装置１Ａ〜１Ｄの投入チャック１１，１１は、２つの受取チャック（２１Ａと２１Ｂ、又は２１Ｂと２１Ｃ）が該投入チャック１１，１１に対応する位置まで移動するまでは、布類両端角部Ｓａ，Ｓａを保持したまま待機しており、該２つの受取チャックが所定位置まで移動したときにコントローラ９からの信号で昇降装置１２を投入チャック上昇側に作動させるようになっている。   In addition, start buttons 13A to 13D are provided in the input devices 1A to 1D, respectively. Then, after holding the cloth both end corners Sa, Sa on both the input chucks 11, 11, when the start buttons 13A-13D of the input devices 1A-1D are pressed, the signals are input to the controller 9 and input The order of operation of the devices is determined. It should be noted that the input chucks 11 and 11 of the input devices 1A to 1D having pressed the start button are moved until the two receiving chucks (21A and 21B or 21B and 21C) move to positions corresponding to the input chucks 11 and 11, respectively. Is waiting while holding both ends of the cloth Sa, Sa, and when the two receiving chucks move to a predetermined position, the lifting device 12 is operated to the closing chuck ascending side by a signal from the controller 9. It has become.

この実施例の布類展張搬送機では、左右展張装置２として、３セットの展開チャック装置２０Ａ〜２０Ｃが使用されている。この各展開チャック装置２０Ａ〜２０Ｃは、それぞれ１つの受取チャック（２１Ａ〜２１Ｃ）と、該各受取チャック（２１Ａ〜２１Ｃ）を所定高さ位置の左右同一直線上においてそれぞれ左右動装置２２Ａ〜２２Ｃで個別に左右移動せしめ得るようにしたものが採用されている。   In the fabric spreading and conveying machine of this embodiment, three sets of developing chuck devices 20A to 20C are used as the left and right spreading device 2. Each of the unfolding chuck devices 20A to 20C includes one receiving chuck (21A to 21C) and each of the receiving chucks (21A to 21C) by left and right moving devices 22A to 22C on the same horizontal line at a predetermined height. The one that can be moved left and right individually is adopted.

各左右動装置２２Ａ〜２２Ｃは、サーボモータ２３Ａ〜２３Ｃと、各台板２４，２４，２４と、該台板２４，２４，２４をガイドする共通のレール２５，２５と、各サーボモータ２３Ａ〜２３Ｃと各台板２４，２４，２４間にそれぞれ個別に掛けられたベルト（タイミングベルト）２６，２６，２６とを有している。各受取チャック（左側受取チャック２１Ａ、中間受取チャック２１Ｂ、右側受取チャック２１Ｃ）は、それぞれ台板２４，２４，２４に取付けられている。   The left and right moving devices 22A to 22C include servo motors 23A to 23C, base plates 24, 24, 24, common rails 25, 25 for guiding the base plates 24, 24, 24, and servo motors 23A to 23C. 23C and belts (timing belts) 26, 26, 26 individually hung between the base plates 24, 24, 24, respectively. Each receiving chuck (the left receiving chuck 21A, the intermediate receiving chuck 21B, and the right receiving chuck 21C) is attached to the base plates 24, 24, and 24, respectively.

そして、この各展開チャック装置２０Ａ〜２０Ｃは、それぞれサーボモータ２３Ａ〜２３Ｃを所定回転方向及び所定回転量だけ作動させることにより、各受取チャック２１Ａ〜２１Ｃをそれぞれ個別に左右方向の所定位置に移動させ得るようになっている。尚、各サーボモータ２３Ａ〜２３Ｃの回転方向及び回転量は、次順の投入装置の位置に基いてコントローラ９で制御される。   The unfolding chuck devices 20A to 20C operate the servo motors 23A to 23C by a predetermined rotation direction and a predetermined rotation amount, respectively, thereby individually moving the receiving chucks 21A to 21C to predetermined positions in the left-right direction. To get. The rotation direction and the rotation amount of each servo motor 23A to 23C are controlled by the controller 9 based on the position of the next input device.

各展開チャック装置２０Ａ〜２０Ｃは、作動順が到来した投入装置１Ａ〜１Ｄの各投入チャック１１，１１に対応する位置に２つの受取チャック（２１Ａと２１Ｂ、又は２１Ｂと２１Ｃ）を移動させるものである。そして、機体１０の中央より左側にある第１投入装置１Ａと第２投入装置１Ｂに対しては、左側受取チャック２１Ａの展開チャック装置２０Ａと中間受取チャック２１Ｂの展開チャック装置２０Ｂとが担当する一方、機体１０の中央より右側にある第３投入装置１Ｃと第４投入装置１Ｄに対しては、中間受取チャック２１Ｂの展開チャック装置２０Ｂと右側受取チャック２１Ｃの展開チャック装置２０Ｃとが担当するようになっている。又、各展開チャック装置２０Ａ〜２０Ｃは、後述するようにコントローラ９からの信号により、それぞれ所定の動作を行うようになっている。   Each of the unfolding chuck devices 20A to 20C moves two receiving chucks (21A and 21B, or 21B and 21C) to positions corresponding to the loading chucks 11 and 11 of the loading devices 1A to 1D in which the operation order has arrived. is there. For the first input device 1A and the second input device 1B on the left side from the center of the machine body 10, the unfolding chuck device 20A of the left receiving chuck 21A and the unfolding chuck device 20B of the intermediate receiving chuck 21B are in charge. The deployment chuck device 20B of the intermediate receiving chuck 21B and the deployment chuck device 20C of the right receiving chuck 21C are in charge of the third charging device 1C and the fourth charging device 1D on the right side from the center of the machine body 10. It has become. Each of the developing chuck devices 20A to 20C performs a predetermined operation in response to a signal from the controller 9, as will be described later.

この実施例の布類展張搬送機では、次のように作動する。   The cloth spreading / conveying machine of this embodiment operates as follows.

各投入装置１Ａ〜１Ｄ部分においては、それぞれ作業員が大面積の布類Ｓの一辺（長辺）の両端角部Ｓａ，Ｓａを捜し出して、その両端角部Ｓａ，Ｓａを一対の投入チャック１１，１１に保持させた後、スタートボタン１３Ａ〜１３Ｄを押す。スタートボタン１３Ａ〜１３Ｄを押すと、それぞれスタート信号がコントローラ９に入力されて、各投入装置１Ａ〜１Ｄの作動順が決められる。尚、スタートボタンを押した後は、当該作業員は次の布類の両端角部Ｓａ，Ｓａの捜し出し準備をすることができるが、当該投入装置の各投入チャック１１，１１が開放されるまでは次の布類を投入チャック１１，１１に保持させることができず、待ち時間ができる。   In each of the charging devices 1A to 1D, each worker searches for both corners Sa and Sa of one side (long side) of the large-sized cloth S, and the both corners Sa and Sa are paired with a pair of charging chucks 11. , 11, the start buttons 13 </ b> A to 13 </ b> D are pressed. When the start buttons 13A to 13D are pressed, start signals are respectively input to the controller 9, and the operation order of the input devices 1A to 1D is determined. Note that after pressing the start button, the worker can prepare for searching for both corners Sa and Sa of the next cloth until the respective feeding chucks 11 and 11 of the feeding device are released. Can not hold the next cloth on the input chucks 11 and 11 and can wait.

そして、図１の例では、第２投入装置１Ｂに作動順が到来した場合を示しているが、この図１の場合には、左側展開チャック装置２０Ａのサーボモータ２３Ａと中間展開チャック装置２０Ｂのサーボモータ２３Ｂとがそれぞれ所定方向及び所定量だけ作動して、左側受取チャック２１Ａ及び中間受取チャック２１Ｂをそれぞれ第２投入装置１Ｂの各投入チャック１１，１１に対応する位置まで移動させる。尚、このときの各サーボモータ２３Ａ，２３Ｂの作動スピートは、各受取チャック２１Ａ，２１Ｂが空の状態であるので、それぞれ２６０ｍ／分（秒速約４.３ｍ）程度の高速作動する。又、使用しない右側受取チャック２１Ｃは、右側展開チャック装置２０Ｃのサーボモータ２３Ｃが作動することにより、布類展張作業に邪魔にならない右側の退避位置まで移動される。   The example of FIG. 1 shows the case where the operation order has arrived at the second input device 1B, but in this case of FIG. 1, the servo motor 23A of the left developing chuck device 20A and the intermediate developing chuck device 20B. The servo motor 23B operates in a predetermined direction and a predetermined amount, respectively, to move the left receiving chuck 21A and the intermediate receiving chuck 21B to positions corresponding to the input chucks 11 and 11 of the second input device 1B, respectively. Note that the servo motors 23A and 23B at this time operate at a high speed of about 260 m / min (about 4.3 m / s) because the receiving chucks 21A and 21B are empty. Further, the unused right-side receiving chuck 21C is moved to the right-side retracted position that does not interfere with the cloth spreading work by the servo motor 23C of the right-side developing chuck device 20C operating.

そして、その直後にコントローラ９からの信号で、第２投入装置１Ｂの各投入チャック１１，１１が布類両端角部Ｓａ，Ｓａを保持したまま上動し→各両端角部Ｓａ，Ｓａを各受取チャック２１Ａ，２１Ｂに受け渡し（図１、図３のＳ1の状態）→各受取チャック２１Ａ，２１Ｂを機体１０の幅方向中心から等距離づつ離れた位置において左右に離間させて（各受取チャック２１Ａ，２１Ｂが符号２１Ａ′，２１Ｂ′の位置まで移動する）布類の上辺部を展張させる（上辺部展張布類Ｓ2となる）。尚、各受取チャック２１，２１Ｂの離間時の移動スピードは、布類に緊張時のダメージを与えないために７０ｍ／分程度の比較的低速に設定されている。続いて、送込みローラ３７が送込み方向に高速回転（図３において右回転）するとともに、切換ダンパ３５が鎖線図示側に切換えられて吸引ボックス３１内の空気が吸引されて、布類の下端側がＳ3の状態を経てＳ4のように吸引ボックス３１内に吸い込まれる。このとき、この布類Ｓ4には、バキュームファン３３の吸引作用により、下方へのテンションがかけられて、該布類が方形状に展張される。その後、送込みローラ３７が停止し→切換ダンパ３５が実線図示側に切換えられ→各受取チャック２１Ａ，２１Ｂが開放されて両受取チャックで保持していた布類Ｓ4の上辺部が吸着ボックス４１の先端側上面に吸着・保持され→該吸着ボックス４１が鎖線図示（図３）するように後退し、そのとき布類上辺部が前側コンベア（バキュームコンベア）５１上に移乗されて（符号Ｓ5の状態）、展張状態のままで前側コンベア５１及び後側コンベア５２を経てプレス機側に搬送される。 Immediately thereafter, the feeding chucks 11 and 11 of the second feeding device 1B are moved upward while holding the cloth both end corners Sa and Sa by a signal from the controller 9 → the both end corners Sa and Sa passing receive chuck 21A, the 21B (FIG. 1, S 1 in the state shown in FIG. 3) → each receive chucks 21A, and 21B were spaced horizontally at a distance equal distance increments from the widthwise center of the machine body 10 (the receiving chuck 21A, 21B is a code 21A ', 21B' moves to the position of) is stretched the upper side of the cloth (upper part stretched cloth S 2). Note that the movement speed of the receiving chucks 21 and 21B when they are separated is set to a relatively low speed of about 70 m / min so as not to damage the fabrics when they are in tension. Subsequently, the feeding roller 37 rotates at a high speed in the feeding direction (right rotation in FIG. 3), and the switching damper 35 is switched to the chain line illustrated side so that the air in the suction box 31 is sucked and the lower end of the cloth The side passes through the state of S 3 and is sucked into the suction box 31 as in S 4 . At this time, a downward tension is applied to the cloth S 4 by the suction action of the vacuum fan 33, and the cloth is stretched in a square shape. Then, infeed roller 37 is stopped → switching damper 35 is solid shown side is switched → each recipient chuck 21A, the upper side portion adsorption box 41 of the 21B cloth retained is open at both receiving chuck S 4 are adsorbed and held on the front end side upper surface → adsorption box 41 is retracted to the chain line shown (FIG. 3), then the cloth upper part is ERROR on the front conveyor (vacuum conveyor) 51 (reference numeral S 5 In this state, the sheet is conveyed to the press side through the front conveyor 51 and the rear conveyor 52 in the expanded state.

他方、上記左側受取チャック２１Ａ′及び中間受取チャック２１Ｂ′が布類展張位置において開放されると、コントローラ９からの信号で直ちに３つの展開チャック装置２０Ａ〜２０Ｃの各受取チャック２１Ａ〜２１Ｃが次順の作動順の投入装置に対応する位置に作動せしめられる。例えば次順の作動順の投入装置が図４に示すように第４投入装置１Ｄである場合には、図１の状態から図４の状態、即ち、左側受取チャック２１Ａが左側退避位置まで移動する一方、中間受取チャック２１Ｂと右側受取チャック２１Ｃとがそれぞれ第４投入装置１Ｄの各投入チャック１１，１１に対応する位置まで高速移動し、以下、上記と同様に各投入チャック１１，１１が布類両端角部Ｓａ，Ｓａを保持したまま上動し→各両端角部Ｓａ，Ｓａを各受取チャック２１Ｂ，２１Ｃに受け渡し→各受取チャック２１Ｂ，２１Ｃを左右に離間（図４の符号２１Ｂ′，２１Ｃ′）させて布類の上辺部を展張させ→吸引装置３により布類の下方部分を吸引・展張させ（図４の展張布類Ｓ2となる）→その後、各受取チャック２１Ｂ，２１Ｃが開放されて布類の上辺部が吸着ボックス４１を介して前側コンベア５１の始端部上に移乗され→布類が展張状態のままで前側コンベア５１及び後側コンベア５２を経てプレス機側に搬送される。 On the other hand, when the left receiving chuck 21A 'and the intermediate receiving chuck 21B' are opened at the cloth extending position, the receiving chucks 21A to 21C of the three unfolding chuck devices 20A to 20C are immediately followed by a signal from the controller 9. It is made to act | operate to the position corresponding to the input device of the order of operation. For example, when the input device in the next operation order is the fourth input device 1D as shown in FIG. 4, the state shown in FIG. 1, that is, the left receiving chuck 21A moves to the left retracted position from the state shown in FIG. On the other hand, the intermediate receiving chuck 21B and the right receiving chuck 21C move at high speed to positions corresponding to the respective input chucks 11 and 11 of the fourth input device 1D, respectively. The upper end corners Sa and Sa are moved upward while being held → the respective end corners Sa and Sa are transferred to the receiving chucks 21B and 21C → the receiving chucks 21B and 21C are separated to the left and right (reference numerals 21B 'and 21C in FIG. 4). ′) The upper part of the cloth is stretched → The lower part of the cloth is sucked and stretched by the suction device 3 (the stretch cloth S 2 in FIG. 4) → Thereafter, the receiving chucks 21B and 21C are opened. The The upper side portion of the cloth is conveyed to the press machine side through the front conveyor 51 and rear conveyer 52 ERROR is → cloth onto the starting end are in the original stretched state of the front conveyor 51 via the suction box 41 Te.

この実施例の布類展張搬送機では、上記のように、４基の各投入装置１Ａ〜１Ｄからそれぞれ布類両端角部Ｓａ，Ｓａを受取る際に、機体中央より左側の２基（第１及び第２）の投入装置１Ａ，１Ｂは左側受取チャック２１Ａと中間受取チャック２１Ｂとで担当し、機体中央より右側の２基（第３及び第４）の各投入装置１Ｃ，１Ｄは中間受取チャック２１Ｂと右側受取チャック２１Ｃとで担当するようになっている。   In the cloth spreading and conveying machine of this embodiment, as described above, when receiving the cloth both-end corners Sa and Sa from the four feeding devices 1A to 1D, respectively, The second receiving device 1A, 1B is in charge of the left receiving chuck 21A and the intermediate receiving chuck 21B, and the two (third and fourth) inputting devices 1C, 1D on the right side from the center of the machine body are intermediate receiving chucks. 21B and the right receiving chuck 21C are in charge.

このようにすると、各受取チャック（２１Ａ〜２１Ｃ）が展張位置において布類両端角部Ｓａ，Ｓａを開放した後、各受取チャック（２１Ａ〜２１Ｃ）が次順の作動順の投入装置（１Ａ〜１Ｄ）に対応する位置まで移動する際に、必ず中間受取チャック２１Ｂが共用されるので、各受取チャック（２１Ａ〜２１Ｃ）を所定位置まで移動させる距離が短くてよい場合が多くなる。例えば、左側受取チャック２１Ａと中間受取チャック２１Ｂとが図１の布類展張位置（２１Ａ′，２１Ｂ′の位置）で右側受取チャック２１Ｃが右側退避位置にある状態から、図４に示すように第４投入装置１Ｄに２つの受取チャックを対応させる際に、中間受取チャック２１Ｂを第４投入装置１Ｄの左側投入チャック１１に対応する位置までの距離Ｌ3（Ｌ3＝１０cm程度）だけ移動させ、右側受取チャック２１Ｃを右側退避位置から第４投入装置１Ｄの右側投入チャック１１に対応する位置までの距離Ｌ4（Ｌ4＝６０cm程度）だけ移動させるとともに、左側受取チャックを左側退避位置（図４の符号２１Ａの位置）までの距離Ｌ5（Ｌ5＝９０cm程度）だけ移動させる。この場合、次順の作動順の投入装置は第４投入装置１Ｄであり、中間受取チャック２１Ｂと右側受取チャック２１Ｃのみが第４投入装置１Ｄの作動待機（待ち時間）の対象になる（左側受取チャック２１Ａは邪魔にならない）が、両受取チャック２１Ｂ，２１Ｃの最大移動距離がＬ4の６０cm程度であるので、受取チャックが該最大移動距離Ｌ4を移動するのに必要な時間（６０cm÷秒速４.３ｍ）は０.１〜０.２秒程度の短時間となる。 In this way, after each receiving chuck (21A to 21C) opens the cloth both end corners Sa and Sa in the extended position, each receiving chuck (21A to 21C) is inserted in the next operation order feeding device (1A to 21A). When moving to the position corresponding to 1D), the intermediate receiving chuck 21B is always used in common, and therefore the distance for moving the receiving chucks (21A to 21C) to the predetermined position is often short. For example, from the state in which the left receiving chuck 21A and the intermediate receiving chuck 21B are in the cloth spreading position (21A ′, 21B ′) in FIG. 1 and the right receiving chuck 21C is in the right retracted position, as shown in FIG. When the two receiving chucks are made to correspond to the 4-input device 1D, the intermediate receiving chuck 21B is moved by a distance L 3 (L 3 = about 10 cm) to the position corresponding to the left-side input chuck 11 of the fourth input device 1D. The right receiving chuck 21C is moved by a distance L 4 (L 4 = about 60 cm) from the right retracting position to a position corresponding to the right inserting chuck 11 of the fourth charging device 1D, and the left receiving chuck is moved to the left retracting position (FIG. 4). Is moved by a distance L 5 (L 5 = about 90 cm). In this case, the charging device in the next operation order is the fourth charging device 1D, and only the intermediate receiving chuck 21B and the right receiving chuck 21C are subjected to the operation waiting (waiting time) of the fourth charging device 1D (left receiving). chuck 21A is unobtrusive) is both receiving chuck 21B, the maximum travel distance of 21C is 60cm approximately L 4, the time required for receiving the chuck moves said maximum travel distance L 4 (60cm ÷ per second 4.3m) is a short time of about 0.1 to 0.2 seconds.

又、図１に示すように、左側受取チャック２１Ａと中間受取チャック２１Ｂを使用して布類展張作業を行った後、次順の作動順の投入装置が第３投入装置１Ｃである場合には、符号２１Ｂ′の位置にある中間受取チャックが第３投入装置１Ｃの左側投入チャック１１に対応する位置までの約１００cmの距離だけ移動する一方、右側退避位置にある右側受取チャック２１Ｃが第３投入装置１Ｃの右側投入チャック１１に対応する位置までの約１５０cmの距離だけ移動する。この場合、両受取チャック２１Ｂ′，２１Ｃの最大移動距離が１５０cm程度であるので、受取チャックが該最大移動距離を移動するのに必要な時間（１５０cm÷秒速４.３ｍ）は０.３〜０.４秒程度の短時間となる。   In addition, as shown in FIG. 1, when the cloth feeding operation is performed using the left receiving chuck 21A and the intermediate receiving chuck 21B, and the charging device in the next operation sequence is the third charging device 1C. The intermediate receiving chuck at the position of 21B 'moves by a distance of about 100 cm to the position corresponding to the left charging chuck 11 of the third charging device 1C, while the right receiving chuck 21C at the right retracted position is the third charging. It moves by a distance of about 150 cm to the position corresponding to the right side loading chuck 11 of the apparatus 1C. In this case, since the maximum moving distance of both receiving chucks 21B ′ and 21C is about 150 cm, the time required for the receiving chuck to move the maximum moving distance (150 cm ÷ 4.3 m / s) is 0.3 to 0. It takes about 4 seconds.

尚、左側受取チャック２１Ａと中間受取チャック２１Ｂとが図１に示す布類展張位置（２１Ａ′と２１Ｂ′の各位置）にある状態で、次順の作動順の投入装置が第１投入装置１Ａである場合には、符号２１Ａ′の位置にある左側受取チャックが第１投入装置１Ａの左側投入チャック１１に対応する位置までの約３０cmの距離だけ移動する一方、符号２１Ｂ′の位置にある中間受取チャックが第１投入装置１Ａの右側投入チャック１１に対応する位置までの約３００cmの距離だけ移動する。この場合、受取チャックが最大移動距離（約３００cm）を移動するのに必要な時間（３００cm÷秒速４.３ｍ）は０.７秒程度となり、図５の従来例と同様になる（受取チャックが移動に要する時間を短縮できない）。   In the state where the left receiving chuck 21A and the intermediate receiving chuck 21B are in the cloth spreading positions (21A ′ and 21B ′) shown in FIG. 1, the input device in the next operation order is the first input device 1A. In this case, the left receiving chuck at the position 21A ′ moves by a distance of about 30 cm to the position corresponding to the left loading chuck 11 of the first charging device 1A, while the intermediate position at the position 21B ′. The receiving chuck moves by a distance of about 300 cm to the position corresponding to the right side loading chuck 11 of the first charging device 1A. In this case, the time required for the receiving chuck to move the maximum moving distance (about 300 cm) (300 cm ÷ 4.3 m / s) is about 0.7 seconds, which is the same as the conventional example of FIG. Ca n’t reduce travel time).

ところで、４基の各投入装置１Ａ〜１Ｄでは、それぞれ布類掛け作業（布類両端角部を各投入チャックに保持させる作業）が継続して行われており、各投入装置１Ａ〜１Ｄのスタートボタン１３Ａ〜１３Ｄによるスタート信号（作動順）は順次交替して出力されている。そして、あるときには２つの受取チャックが移動する距離（移動時間）が長い場合もあるが、平均すると受取チャックの移動に要する時間をかなり短縮できる。   By the way, in each of the four feeding devices 1A to 1D, the cloth hanging work (work for holding the corners of both ends of the fabric on the respective feeding chucks) is continuously performed, and the respective feeding devices 1A to 1D are started. The start signals (operation order) by the buttons 13A to 13D are sequentially output in turn. In some cases, the distance (movement time) by which the two receiving chucks move may be long, but on average, the time required to move the receiving chuck can be considerably shortened.

従って、この実施例の布類展張搬送機では、１枚当たりの布類の処理時間を、受取チャックの移動距離を短縮できる分だけ時間短縮でき、それによって布類の処理能率を向上させることができる。又、３つの受取チャック２１Ａ〜２１Ｃのうちの中間受取チャック２１Ｂを毎回共用させるので、該中間受取チャック２１Ｂの展開チャック装置２０Ｂを有効利用できる。   Therefore, in the cloth spreading and conveying machine of this embodiment, the processing time of the cloth per sheet can be shortened by an amount that can reduce the moving distance of the receiving chuck, thereby improving the cloth processing efficiency. it can. Further, since the intermediate receiving chuck 21B among the three receiving chucks 21A to 21C is shared every time, the deploying chuck device 20B of the intermediate receiving chuck 21B can be effectively used.
