Description

本願発明は、シーツや布団包布のような大面積の布類を展張させ、その展張布類を次工程側に搬送させるための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 machine for spreading a cloth having a large area such as a sheet or a futon wrapping and transporting the spreading cloth to the next process side.

例えば、ランドリー工場においては、洗濯・乾燥後の布類を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, washing and drying cloths are pressed with a pressing machine or folded with a folding machine, and the cloth is placed in the next process device (hereinafter described with a pressing machine). When supplying, it is necessary to preliminarily spread the cloth.

ところで、シーツや布団包布のような大面積の布類を展張させるとともに、その展張布類を次工程側に搬送させ得るようにした布類展張搬送機として、例えば特開2001−159067号公報(特許文献1)に示されるものがある。   By the way, as a fabric spreading and conveying machine that can stretch a large area of cloth such as a sheet or a futon wrapping and can transport the stretched cloth to the next process side, for example, Japanese Patent Application Laid-Open No. 2001-159067. There is what is shown by (patent document 1).

この公知例(特許文献1)の布類展張搬送機は、大面積の布類の一辺の両端角部を投入装置の一対の投入チャックで掴持した状態で所定高位置まで吊上げ、その布類の各掴持部分を上方で待機している一対の受取チャックで受け取り、その各受取チャックを機枠中央部において左右に離間させることにより布類を吊上げ状態で展張させ、その吊上げ展張布類を受渡し装置を介して搬送装置に移乗させて次工程(プレス工程)側に搬送させ得るようになっている。又、吊上げ展張状態の布類は、下方の吸気ボックス内に垂れ下げた状態で該吸気ボックス内を吸引することによって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ようになっている。尚、投入装置の外形下端部は、布類両端角部を各投入チャックに掴持させるために作業員の肩又は顔の高さ付近に位置している。   The cloth spreading and conveying machine of this known example (Patent Document 1) is lifted to a predetermined height in a state where both end corners of one side of a large area cloth are gripped by a pair of input chucks of the input device, and the cloth Each gripping part is received by a pair of receiving chucks waiting at the upper side, and each receiving chuck is separated from the left and right at the center of the machine frame to expand the cloth in a lifted state. It can be transferred to a transport device via a delivery device and transported to the next process (press process) side. Further, the cloth in the lifted and stretched state is stretched downward by sucking the inside of the intake box while being suspended in the lower intake box, so that the cloth is stretched in a square shape. It has become. Note that the lower end of the outer shape of the dosing device is located near the height of the shoulder or face of the operator so that the both end corners of the cloth are gripped by the respective dosing chucks.

ところで、この種の布類展張搬送機(例えば、上記特許文献1のもの)で布類を展張・搬送させる場合に、洗濯・乾燥済みの布類(絡まったり丸まっている)をある程度ほぐし、そのほぐした布類の一辺の両端角部を捜し出して、その両端角部を投入装置の各投入チャックに掴持させるまでは作業員が手作業で行うが、絡まったり丸まった状態の布類を投入チャック側に投入するまでにはかなりの時間(例えば1枚当たり10〜20秒程度)を要する。他方、布類展張搬送機は、布類両端角部を投入チャックが掴持した後、スタートボタンを押すと、布類が吊上げられ→各受取チャックで布類両端角部を受け取り→両受取チャックが左右に離間して布類上辺部を展張させ→吸引装置で布類下方部を吸引し→布類上辺部を搬送装置側に受け渡す、という一連の動作が連続して行われるが、この1回当たりの動作時間は、かなり短い(シーツの場合、例えば4〜5秒程度)ものである。   By the way, when cloths are spread and conveyed by this type of cloth spreading and conveying machine (for example, the one of Patent Document 1), loosened and dried cloths (entangled or curled) are loosened to some extent. It is done by hand until the corners of one side of the loosened cloth are searched and the corners of each side are gripped by the input chucks of the input device. It takes a considerable amount of time (for example, about 10 to 20 seconds per sheet) to be loaded on the chuck side. On the other hand, in the fabric spreading and conveying machine, when the start chuck is held after the both end corners of the fabric are gripped by the input chuck, the fabric is lifted up → the receiving end corners are received by each receiving chuck → both receiving chucks A series of operations are performed continuously such that the upper side of the cloth is stretched away from the left and right, the lower part of the cloth is sucked by the suction device, and the upper side of the cloth is transferred to the conveying device side. The operation time per time is considerably short (in the case of a sheet, for example, about 4 to 5 seconds).

そして、この種の布類展張搬送機には、1台につき投入装置を左右に複数箇所(例えば3〜4箇所)並設し、各投入装置からそれぞれ布類を投入することで、できるだけ機械の待ち時間を少なくする(機械の実質稼働時間を多くする)ようにしている。尚、このように布類の投入装置を左右に3箇所以上設置する場合は、機枠の中央寄りと機枠の左右各端部寄りにそれぞれ所定の間隔をもって配置されるが、省スペースや機枠の小型化等の要望から各投入装置間の間隔はさほど大きく取れない(隣接する投入装置間に作業員が入れるほどの間隔はない)のが現状である。   In this type of cloth spreading and conveying machine, a plurality of feeding devices (for example, 3 to 4 locations) are arranged in parallel on the left and right sides, and the fabrics are fed from each of the feeding devices. The waiting time is reduced (the actual operating time of the machine is increased). When three or more cloth input devices are installed on the left and right in this way, they are arranged at predetermined intervals near the center of the machine frame and the left and right ends of the machine frame. At present, the space between the input devices cannot be so large due to demands such as downsizing of the frame (there is no space between the adjacent input devices so that an operator can enter).

上記公知例(特開2001−159067号公報)に示される布類展張搬送機では、吊上げ展張状態の布類の下部を吸気ボックス内に入れて該吸気ボックス内を吸引することにより、ある程度の展張状態を確保できるものの、該布類に皺や波打ち部分が残ることがある。特に、図5(A)に示すような片面中央部に丸ぐり部Scを有した布団包布Sや、図5(B)に示すような一側縁に開口部Sdを有した袋状の布団包布S等では、表裏生地が接合する部分があって、その表裏生地同士が部分的にくっついて皺や波打ち部分(符号Se)が顕著に残り易い。そして、このように皺があったり波打った状態の展張布類をそのまま後送してプレス機にかけると、該皺や波打ち部分を折返し状態で押し潰して明確な折り皺が発生し、見栄えが悪くなるとともに顧客からの苦情が出ることになる。   In the cloth spreading / conveying machine shown in the above known example (Japanese Patent Laid-Open No. 2001-159067), a certain amount of stretching is achieved by putting the lower part of the cloth in a suspended and stretched state into the intake box and sucking the inside of the intake box. Although the state can be secured, wrinkles and wavy portions may remain on the cloth. In particular, a futon wrap S having a rounded portion Sc at the center of one side as shown in FIG. 5A, or a bag-like shape having an opening Sd at one side edge as shown in FIG. 5B. In the futon wrapping S or the like, there are portions where the front and back fabrics are joined, and the front and back fabrics are partially adhered to each other, so that wrinkles and wavy portions (reference symbol Se) tend to remain remarkably. Then, when the stretched fabrics with wrinkles or undulations are fed as they are and applied to the press machine, the wrinkles and wavy portions are crushed in a folded state, and a clear crease is generated. As customers get worse, customer complaints come out.

ところで、布類の吊上げ展張状態(布類両端角部をそれぞれ受取チャックで掴持して左右に離間させた状態)で、その吊上げ展張布類の左右各側縁部を作業員が手で摘まんで揺する(はためかす)と、皺や波打ち部分を無くすのに有効であるが、その作業には吊上げ展張布類の左右各側縁部に作業員が近づく必要がある。   By the way, when the cloth is lifted and stretched (with both corners of the cloth gripped by the receiving chuck and separated from the left and right sides), the operator grips the left and right side edges of the lifted stretch cloth by hand. Shaking (flapping) is effective in eliminating wrinkles and undulations, but it is necessary for the worker to approach the left and right side edges of the lifted stretch fabric.

特開2001−159067号公報JP 2001-159067 A

ところで、上記のように1台の布類展張搬送機に投入装置を3〜4箇所並設したものでは、機枠中央部で吊上げ展張される布類の左右側縁部を作業員が手で摘まもうとしても(布類側縁部を揺するため)、吊上げ展張布類の左右各側縁部の外側近傍位置にはそれぞれ外側投入装置(下端部が肩又は顔の高さにある)が位置しているので、該外側投入装置が邪魔になって布類側縁部付近に近ずくことができない。   By the way, in the case where 3 to 4 feeding devices are arranged side by side in one cloth spreading / conveying machine as described above, the operator manually handles the left and right side edges of the cloth to be hung and stretched at the center of the machine frame. Even if you try to pick it up (to shake the fabric side edge), there is an outside feeding device (the lower end is at the shoulder or face height) in the position near the outside of the left and right side edges of the lifted stretch fabric. Therefore, the outer charging device becomes in the way and cannot approach the vicinity of the cloth side edge.

従って、1台の布類展張搬送機に投入装置を3〜4箇所並設したものでは(この場合、各投入装置からそれぞれ布類を投入することで機械の実質稼働率を良くすることができる)、布類に頑固な皺や波打ち部分等がある場合に、機械の性能のみでは十分な展張精度を得られないことがあった(その場合には、見栄えが悪くなるとともに顧客からの苦情が出る)。   Therefore, in the case where 3 to 4 feeding devices are arranged side by side on one fabric spreading and conveying machine (in this case, the actual operating rate of the machine can be improved by feeding the fabrics from each feeding device. ) When there are stubborn wrinkles and wavy parts on the fabric, the machine performance alone may not provide sufficient stretch accuracy (in that case, it will not look good and customer complaints may occur) Come out).

そこで、本願発明は、1台の布類展張搬送機に投入装置を3〜4箇所並設したものであっても、機枠中央部で吊上げ展張された布類の左右各側縁部を必要に応じて作業員が手で摘まむ(皺取りのために布類側縁部を揺らす)ことができるようにすることを目的としている。   Therefore, the present invention requires left and right side edges of the cloth that is lifted and stretched at the center of the machine frame, even if 3 to 4 feeding devices are juxtaposed on one cloth stretching and conveying machine. The purpose is to allow the operator to pick it by hand (shake the side edge of the cloth to remove wrinkles).

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.

本願発明は、機枠の前部においてシーツや布団包布のような大面積の布類の一辺の両端角部を投入装置の各投入チャックでそれぞれ掴持して所定高位置まで吊上げ、その吊上げ布類の各掴持部分を受取チャックで受け取って機枠中央部において左右に離間させることにより布類を吊上げ状態で展張させた後、その展張布類を次工程側に搬送させ得るようにした布類展張搬送機を対象にしている。   The invention of the present application grips both corners of one side of a large-sized fabric such as a sheet or a futon wrapping at the front part of the machine frame with each input chuck of the input device and lifts it up to a predetermined position. After receiving each gripping part of the cloth with the receiving chuck and separating it left and right at the center of the machine frame, the cloth can be stretched in a lifted state, and then the stretched cloth can be conveyed to the next process side. Intended for fabric spreading and transporting machines.

投入装置は、肩幅程度の間隔をもって左右一対の投入チャックを有しているとともに、各投入チャックを昇降装置により下方の投入位置と上方の受渡し位置との間で上下動させ得るようになっている。尚、投入チャック用の昇降装置は支持枠に取付けられているが、該支持枠を含めて投入装置を構成している。   The input device has a pair of left and right input chucks at intervals of about the shoulder width, and each input chuck can be moved up and down between the lower input position and the upper delivery position by the lifting device. . The raising / lowering device for the feeding chuck is attached to the support frame, and the feeding device is configured including the support frame.

各受取チャックは、左右動装置により個別に左右移動し得るようになっている。又、布類展張時には、各受取チャックが布類を機枠の中央部で展張させるようになっている。   Each receiving chuck can be individually moved left and right by a left and right moving device. Further, when the fabric is stretched, each receiving chuck stretches the fabric at the central portion of the machine frame.

本願発明の布類展張搬送機では、投入装置は、機枠中央部付近に位置する少なくとも1つの中央投入装置と、機枠中央部で展張される展張布類の左右側縁部のそれぞれ外側近傍に位置する左右2つの外側投入装置との少なくとも3箇所に設置している。   In the cloth spreading and conveying machine according to the present invention, the feeding device includes at least one central feeding device located near the center of the machine frame and the vicinity of the outer sides of the left and right side edges of the stretched fabrics stretched at the machine frame center. Are installed at at least three places with the two left and right outer charging devices.

中央投入装置は、1つでも複数でもよいが、複数の場合でも2つが適当である。尚、外側投入装置は左右に1つずつである。   One or a plurality of central loading devices may be used, but two are appropriate even in a plurality of cases. Note that there is one outer loading device on each side.

そして、この布類展張搬送機では、各外側投入装置は、それぞれ上下動装置により投入チャックが作業員の伸長より低くなる下方の使用位置と投入装置全体が作業員の身長より上方に退避する退避位置との間で上下動させ得るようにしている。各上下動装置としては、エアシリンダが採用できる。尚、中央投入装置にも、下方の使用位置と上方の退避位置との間で上下動させ得る上下動装置を設けることができるが、その場合は外側投入装置用の各上下動装置とは別のものを使用する。   In this cloth spreading and conveying machine, each outer loading device is moved down by the vertical movement device so that the loading chuck is lower than the extension of the worker and the entire loading device is retracted above the height of the worker. It can be moved up and down between positions. An air cylinder can be adopted as each vertical movement device. The central throwing device can also be provided with a vertical movement device that can be moved up and down between the lower use position and the upper retraction position. In this case, it is different from the vertical movement devices for the outer loading device. Use the ones.

本願発明の布類展張搬送機では、全部(3〜4箇所)の投入装置を使用位置に位置させて該各投入装置からそれぞれ布類を投入し得るようにした使用形態と、左右の各外側投入装置をそれぞれ上方に退避させて中央投入装置からのみ布類を投入するようにした使用形態とを選択できる。   In the cloth spreading and conveying machine according to the present invention, all (three to four) feeding devices are positioned at the use positions so that the cloths can be fed from the feeding devices, and the left and right outer sides. It is possible to select a usage form in which the dosing device is retracted upward and the cloths are fed only from the central pouring device.

ところで、本願発明の布類展張搬送機では、全部の投入装置を使用位置に位置させて作業を行う場合は、投入装置の投入チャックに布類両端角部を掴持させた後、スタートボタンを押すと、上方位置にある一対の受取チャックが当該投入装置の各投入チャックに対応する位置(受け取り位置)に移動し→各投入チャックが上動して布類が吊上げられ→各受取チャックで布類両端角部を受け取り→両受取チャックが左右に離間して布類上辺部を機枠中央部において展張させ→吸引装置で布類下方部を吸引し→布類上辺部を搬送装置側に受け渡す、という一連の動作が連続して行われる。他方、各外側投入装置を上方の退避位置に位置させた状態では、上記工程の途中の両受取チャックが左右に離間して布類上辺部を機枠中央部で展張させたときに一旦動作が中断し、その後、再度スタートボタンを押すことで以降の動作が再開されるようになっている。   By the way, in the cloth spreading and conveying machine of the present invention, when performing the operation with all the feeding devices positioned at the use position, after holding the cloth both end corners on the feeding chuck of the feeding device, press the start button. When pressed, the pair of receiving chucks in the upper position move to positions (receiving positions) corresponding to the respective input chucks of the input device → the input chucks move upward and the cloths are lifted → the cloths at the respective input chucks Receives both corners → Both receiving chucks are spaced apart from each other and the upper part of the cloth is stretched at the center of the machine frame → The lower part of the cloth is sucked by the suction device → The upper part of the cloth is received by the conveying device side A series of operations of passing is performed continuously. On the other hand, in a state where each outer feeding device is positioned at the upper retracted position, the operation is temporarily performed when both receiving chucks in the middle of the above process are separated from each other left and right and the upper side of the cloth is stretched at the center of the machine frame. The subsequent operation is resumed by interrupting and then pressing the start button again.

そして、シーツのような1枚ものの布類では、機械の展張機能のみで比較的きれいに展張させることができるので、全部(3〜4箇所)の投入装置を使用して機械の実質稼働率を上げるように実施する。他方、布団包布のように機械の展張機能のみでは皺や波打ち部分をきれいに展張できにくい布類では、次のように実施する。   And with a single piece of cloth such as a sheet, it can be stretched relatively cleanly only with the machine's stretch function, so all the (three to four places) input devices are used to increase the actual operating rate of the machine. Implement as follows. On the other hand, in the case of cloths such as futon wrapping, where it is difficult to clean the wrinkles and undulations with just the spreading function of the machine, it is carried out as follows.

まず、中央投入装置は使用位置のままで、左右の各外側投入装置をそれぞれ上下動装置により上方の退避位置に位置させる。このように各外側投入装置を上方に退避させると、該各外側投入装置の下方にそれぞれ作業員が入れるスペースができる。そして、中央投入装置に布類投入用の作業員と、上記各スペースに側縁部処理用の作業員を1人ずつ配置する。   First, while the central throwing device remains in the use position, the left and right outer throwing devices are respectively positioned at the upper retracted position by the vertical movement device. Thus, when each outer charging device is retracted upward, a space for workers to enter is created below each outer charging device. Then, a cloth input worker is arranged in the central input device, and one side edge processing worker is arranged in each space.

この状態で、布類投入用作業員が布類の一辺両端角部を捜し出してその両端角部を中央投入装置の各投入チャックに掴持させた後、スタートボタンを押すと、上記のように作動して両受取チャックが離間して布類上辺部を機枠中央部において展張させたときに、動作が一旦中断する。この状態では、中央投入装置の奥側で布類の一辺両端角部がそれぞれ受取チャックで保持されていて該布類が吊上げ状態で展張されているが、その吊上げ展張布類の左右各側縁部は、それぞれ側縁部処理用の各作業員の手が届く位置にある。そして、その左右の布類側縁部を2人の側縁部処理用作業員がそれぞれ手で摘まんで、該各布類側縁部をそれぞれ揺する(はためかす)。このとき、布団包布のような2枚重ね部分がある布類では、表裏の生地間に部分的に空気が留まって頑固な皺や波打ち部分が生じ易いが、上記のように布類側縁部を揺すると表裏生地間に空気を送り込むことができるので、布団包布であっても皺や波打ち部分をきれいに除去できる。その後、再度スタートボタンを押すと、吸引装置で布類下方部を吸引し→布類上辺部を搬送装置側に受け渡し→該搬送装置により布類を次工程(プレス工程)側に後送する。   In this state, when the cloth throwing worker searches for the corners on both ends of the cloth and grips the corners of the cloths on the respective closing chucks of the central charging device, pressing the start button, as described above. The operation is temporarily interrupted when the receiving chucks are separated and the upper side of the cloth is stretched at the center of the machine frame. In this state, the corners on one side of the cloth are held by the receiving chuck on the back side of the center throwing device, and the cloth is stretched in the lifted state, but the left and right side edges of the lifted stretch cloth Each part is in a position where each worker's hand for processing the side edge can reach. Then, the two side edge processing workers pick the left and right fabric side edges with their hands, and shake the fabric side edges respectively. At this time, in fabrics with two overlapping parts such as futon wraps, air is likely to stay between the fabrics on the front and back sides, and stubborn wrinkles and undulations are likely to occur. When the part is shaken, air can be sent between the front and back fabrics, so that the wrinkles and wavy parts can be removed cleanly even with a futon wrap. Thereafter, when the start button is pressed again, the lower part of the cloth is sucked by the suction device → the upper side of the cloth is transferred to the conveying device side → the cloth is post-delivered to the next process (pressing process) side by the conveying device.

本願発明の布類展張搬送機には、次のような効果がある。   The cloth spreading conveyor of the present invention has the following effects.

本願発明の布類展張搬送機では、機枠前面部の少なくとも3箇所に投入装置を設けており、皺や波打ち部分が残りにくい布類(例えば1枚もののシーツ)については全部の投入装置から布類を投入できるようにしているので、機械の実質稼働率を良好にし得る(機械の待ち時間をなくするか少なくできる)。   In the cloth spreading and conveying machine according to the present invention, a feeding device is provided in at least three positions on the front surface of the machine frame. For cloths (for example, one sheet of sheets) in which wrinkles and wavy portions are difficult to remain, the cloth is fed from all the feeding devices. Since the machine can be introduced, the actual operating rate of the machine can be improved (the waiting time of the machine can be eliminated or reduced).

又、そのように、少なくとも3箇所に投入装置を設けたものであっても、各外側投入装置をそれぞれ上方(邪魔にならない位置)に退避させることにより、その各外側投入装置の下方に作業員が入るスペースを確保できる。従って、その左右のスペースから、機枠中央部で吊上げ展張される布類の左右側縁部を作業員が摘まんで揺する(皺取りする)ことができるので、布団包布のような皺や波打ち部分が残り易い布類であっても、展張精度の良好な展張布類に仕上げることができる。   In addition, even in the case where the charging devices are provided in at least three places, the workers are placed below the outer charging devices by retracting the outer charging devices upward (positions that do not get in the way). Space for entering can be secured. Therefore, from the left and right spaces, workers can pick and shake (catch off) the left and right edges of the fabric that is lifted and stretched at the center of the machine frame. Even if the cloth tends to remain, it can be finished into a stretchable cloth with good stretch accuracy.

さらに、上記各使用形態は、左右の各外側投入装置を上下動装置(エアシリンダ)で上下動させる、という簡単な構成の付加で行えるので、装置として安価に製作できる。   Furthermore, since each said usage form can be performed by addition of the simple structure of moving up and down each left and right outer injection | throwing-in apparatus with a vertical movement apparatus (air cylinder), it can be manufactured cheaply as an apparatus.

以下、図1〜図4を参照して本願実施例を説明すると、この実施例の布類展張搬送機は、例えばランドリー工場において洗濯・乾燥済みのシーツや布団包布等の大面積布類をきれいに展張させた状態で次工程(プレス工程)側に搬送させるものである。尚、図1及び図2には、後述するように全部の投入装置(1A,1B)を使用してそれぞれの投入装置から布類を投入する使用形態を示しており、図3及び図4には、後述するように投入装置(1A,1B)の一部(中央投入装置1A)のみを使用してその一部の投入装置から布類を投入する使用形態を示している。   Hereinafter, the embodiment of the present application will be described with reference to FIGS. 1 to 4. The cloth spreading / conveying machine of this embodiment is a large area cloth such as a sheet or a futon wrapping cloth which has been washed and dried in a laundry factory, for example. It is conveyed to the next process (press process) side in a state of being neatly spread. FIGS. 1 and 2 show usage forms in which cloths are fed from the respective feeding devices using all the feeding devices (1A, 1B), as will be described later. Shows a mode of use in which cloths are fed from a part of the feeding devices using only a part of the feeding devices (1A, 1B) (central feeding device 1A), as will be described later.

The fabric rear surface expansion device 6 is a basic configuration.

機枠10の前面部には、左右にかなり広幅(例えば3m程度の幅)の空間部が形成されている。この機枠10の前面空間部には、その中央部に1つの中央投入装置1Aと、左右各外端寄り位置に1つずつの外側投入装置1B,1Bがそれぞれ設置されている。   On the front part of the machine frame 10, a space part having a fairly wide width (for example, a width of about 3 m) is formed on the left and right. In the front space portion of the machine casing 10, one central loading device 1A is installed at the center, and one outer loading device 1B, 1B is installed near each of the left and right outer ends.

中央投入装置1Aは、比較的広幅(例えば150〜160cm幅)で1枚ものの支持枠13を有し、該支持枠13の左右に離間した2箇所にそれぞれ左右一対を1組とする2組の投入チャック11,11を設置している。この2組の各投入チャック11,11は、それぞれ昇降装置(ロッドレスシリンダ)12で個別に昇降させ得るようになっている。   The central loading device 1A has a relatively wide width (for example, 150 to 160 cm) and a single support frame 13, and two sets of left and right pairs of the support frame 13, each pair of left and right. Input chucks 11 and 11 are provided. Each of the two sets of input chucks 11 and 11 can be individually moved up and down by a lifting device (rodless cylinder) 12.

このように、4箇所の投入部からそれぞれ布類を投入し得るようにした第1使用形態では、投入チャック11,11に布類両端角部を掴持させた後にスタートボタンを押すと、各受取チャック21,21が布類両端角部の受取位置まで移動する工程から展張布類が搬送装置5(搬出コンベア52)で次工程側に搬送されるまでの全工程をノンストップで連続作動するようになっている。   As described above, in the first usage mode in which the cloths can be loaded from the four loading parts, when the start chuck is pushed after the cloth chucks 11 and 11 have gripped the cloth corners, All the processes from the process in which the receiving chucks 21 and 21 are moved to the receiving position at both corners of the cloth until the stretched cloth is conveyed to the next process side by the conveying device 5 (unloading conveyor 52) are continuously operated in a non-stop manner. It is like that.

各投入部においては、それぞれ一対の投入チャック11,11に布類両端角部を掴持させた後にそれぞれスタートボタンが押されるが、受取チャック21,21が作動中(先の布類の角部を保持している状態)では該投入チャック11,11が布類両端角部を掴持したまま待機している。又、受取チャック21,21は、先の布類を開放した後、直ちに次順(スタートボタンが押されている)の投入チャック11,11に対応する位置に移動して、次の布類受け取り動作が行われる。そして、図1及び図2の第1使用形態では、機枠前面部の4箇所からそれぞれ布類を投入できるので、機械の限界処理能力と同等あるいはそれを超えた布類投入能力があり、従って機械の待ち時間をなくして機械の実質稼働率を最大限まで高めることができる。   In each loading portion, the start button is pressed after the pair of loading chucks 11 and 11 are gripped by the corners on both ends of the cloth, but the receiving chucks 21 and 21 are in operation (the corners of the previous cloth). In this state, the input chucks 11 and 11 are on standby while gripping both corners of the cloth. The receiving chucks 21 and 21 immediately move to the positions corresponding to the input chucks 11 and 11 in the next order (the start button is pressed) after releasing the previous cloth, and receive the next cloth. Operation is performed. In the first usage pattern shown in FIGS. 1 and 2, since cloths can be fed from four locations on the front surface of the machine frame, there is a cloth throwing capacity equal to or exceeding the limit processing capacity of the machine. By eliminating the waiting time of the machine, the actual operation rate of the machine can be maximized.

尚、図1及び図2の第1使用形態では、布類に対して機械による展張作用だけしかないが、シーツのような1枚ものの布類では、機械の展張作用のみでも十分きれいに展張させることができる。   In the first usage pattern shown in FIGS. 1 and 2, only the stretching action by the machine is applied to the cloth. However, in the case of a single piece of cloth such as a sheet, the cloth should be sufficiently neatly stretched only by the stretching action of the machine. Can do.

他方、例えば図5(A)(B)に示す布団包布(表裏生地が重合する部分がある)のように機械による展張作用のみでは皺や波打ち部分Seが残り易い布類Sの場合は、図3及び図4の第2使用形態で行うとよい。この第2使用形態では、各外側投入装置1B,1Bをそれぞれ上方の退避位置に跳ね上げて(各外側投入装置1B,1Bの下方にそれぞれ作業員が入るスペースができる)、中央投入装置1A(2箇所の投入部がある)の前面に布類投入用の2人の作業員M1,M2を配置する一方、各外側投入装置1B,1Bの下方スペースにそれぞれ側縁部処理用の1人ずつの作業員M3,M4を配置する。 On the other hand, in the case of a fabric S in which wrinkles and corrugated portions Se are likely to remain only by a stretching action by a machine, such as a futon wrapping cloth (there is a portion where the front and back fabrics are superposed) shown in FIGS. 5 (A) and 5 (B), It is good to carry out by the 2nd usage pattern of FIG.3 and FIG.4. In this second mode of use, each outer loading device 1B, 1B is flipped up to the upper retracted position (there is a space for workers to enter below each outer loading device 1B, 1B), and the central loading device 1A ( Two workers M 1 and M 2 for inputting fabrics are arranged on the front of the two input units), while one side edge processing unit is provided in the space below each of the outer input devices 1B and 1B. Personnel workers M 3 and M 4 are assigned.

そして、布類投入用の各作業員M1,M2がそれぞれの投入部の各投入チャック11,11に布類両端角部Sa,Sa掴持させた後、当該投入部のスタートボタンを押すが、この第2使用形態では、スタートボタンが押されると、上記と同様に各受取チャック21,21が受取位置に移動し→当該各投入チャック11,11が布類両端角部Sa,Saを掴持したまま上動し→該各角部Sa,Saを各受取チャック21,21に受け渡し(符号S1の状態)→各受取チャック21,21が機枠中央部において左右に離間して布類の上辺部を展張させる(符号S2の状態)。そして、この第2使用形態の場合は、各受取チャック21,21で布類S2を吊上げ展張させた状態で動作が一旦中断し、その中断中に布類展張補助用の各作業員M3,M4がそれぞれ吊上げ展張布類S2の左右各側縁部Sa,Saを手で摘まんで揺すり(はためかす)、布類の皺や波打ち部分Seを除去する。そして、ある程度皺や波打ち部分Seを除去した後、再度スタートボタンを押すと、以降の動作が再開されて、展張布類S2の下部側を吸気ボックス31内に吸い込み(符号S3の状態)→布類S3の上辺部分が吸着ボックス41を介して吸着コンベア51の始端部上に移乗され(符号S4の状態)→該布類S4が上方に引き上げられることで順次各拡張ベルト61,61で左右外側に展張されながら吸着コンベア51及び搬出コンベア52上を後送される。 Then, after each worker M 1 , M 2 for inputting the cloth makes the respective input chucks 11, 11 of the respective input sections grip the cloth both end corners Sa, Sa, the start button of the input section is pressed. However, in this second mode of use, when the start button is pressed, the receiving chucks 21 and 21 are moved to the receiving position in the same manner as described above. → The input chucks 11 and 11 move the cloth corners Sa and Sa. gripping the left upward and → respective corner portion Sa, passing to each receive a chuck 21, 21 a Sa (state code S 1) → each recipient chucks 21, 21 at a distance from each other in the right and left in the machine frame central portion cloth It is stretched the upper side portion of the class (state code S 2). In the case of this second usage pattern, the operation is temporarily interrupted while the cloth S 2 is lifted and stretched by the receiving chucks 21 and 21, and each worker M 3 for assisting the cloth stretching is suspended during the interruption. , M 4 respectively pick up and shake the left and right side edges Sa, Sa of the lifted and stretched cloth S 2 by hand, and remove the wrinkles and corrugated parts Se of the cloth. Then, after removing the wrinkles and the wavy part Se to some extent, when the start button is pressed again, the subsequent operation is resumed, and the lower side of the stretch fabric S 2 is sucked into the intake box 31 (state of S 3 ) → upper portion of the cloth S 3 is ERROR on starting end of the suction conveyor 51 through the suction box 41 (status code S 4) → cloth such S 4 sequentially each extended by is pulled upward belt 61 , 61, the sheet is fed back on the suction conveyor 51 and the carry-out conveyor 52 while being extended to the left and right outer sides.

この第2使用形態の場合では、布類投入部が2箇所であり且つ布類を吊上げ展張状態(符号S2の状態)で一時停止させる必要があることから処理能力が低下するものの、左右各外側投入装置1B,1Bを上方退避位置に跳ね上げることにより、その各下方スペースから作業員M3,M4が吊上げ展張布類S2の各側縁部Sb,Sbをそれぞれ摘まんで揺する(皺取り操作をする)ことができる。従って、布団包布のような皺や波打ち部分Seが残り易い布類Sであっても、きれいに展張させて後送することができ、品質の良好な布類に加工できる。 In the case of this second usage pattern, although there are two cloth input portions and the cloth needs to be suspended and suspended in the stretched state (state of S 2 ), the processing capacity decreases, By flipping up the outer loading devices 1B and 1B to the upper retreat position, the workers M 3 and M 4 pick up and swing the side edges Sb and Sb of the stretchable fabric S 2 from the respective lower spaces, respectively (皺) Can be taken out). Therefore, even if the cloth S, such as a futon wrap, in which wrinkles and wavy portions Se are likely to remain, it can be neatly spread and sent later, and can be processed into a good quality cloth.

このように、この実施例の布類展張搬送機では、左右各外側投入装置1B,1Bをそれぞれ上下動装置(エアシリンダ)15B,15Bで下方の使用位置と上方の退避位置との間で変位させるという簡単な構成で、高速処理を重視した上記第1使用形態と高品質処理を重視した上記第2使用形態とに使い分けができる。   As described above, in the cloth spreading and conveying machine of this embodiment, the left and right outer loading devices 1B and 1B are displaced between the lower use position and the upper retraction position by the vertical movement devices (air cylinders) 15B and 15B, respectively. With this simple configuration, the first usage pattern that emphasizes high-speed processing and the second usage pattern that emphasizes high-quality processing can be used properly.
