Abstract

PROBLEM TO BE SOLVED: To provide a square cloth spreading apparatus in which square cloth can be smoothly and reliably dropped in a shaping duct.SOLUTION: A square cloth spreading apparatus includes: a suction mechanism which includes a shaping duct 65 for sucking the lower part of square cloth Y held in front of the spreading apparatus downward to remove wrinkles or the like; and an air blowing device 90 which jets air to the square cloth Y held in front of the spreading apparatus to push the square cloth Y into the shaping duct 65. While the square cloth Y is moved from the front of the spreading apparatus to a delivery position, the lower part of the square cloth Y is pushed into the upper part of the shaping duct 65 by wind pressure caused by jetting air from the air blowing device 90. As a result, suction force in the shaping duct 65 is easily applied to the square cloth Y, so that the square cloth Y can be smoothly and reliably fed into a subsequent process apparatus.SELECTED DRAWING: Figure 1

Description

本発明は、方形状布類展開装置に関する。さらに詳しくは、洗濯済みのシーツなどの方形状布類を四角形に展開し、プレスや折り畳み機などの次工程装置に供給するための方形状布類展開装置に関する。   The present invention relates to a rectangular cloth unfolding apparatus. More specifically, the present invention relates to a rectangular cloth unfolding apparatus for unfolding rectangular cloth such as washed sheets into a square and supplying it to a next process apparatus such as a press or a folding machine.

ホテルや病院などでは大量にシーツが使用され、その使用済みのシーツはランドリー工場で洗濯、アイロンがけされ、再度ホテルや病院などで使用されることが一般的である。
ランドリー工場においては、シーツなどの四角形で比較的大きな寸法を有する方形状布類を、洗濯したあとプレス機でプレスしたり、折り畳み機で折りたたんだりする作業が行なわれる。それらの処理装置に方形状布類を供給するには、方形状布類を予め四角形に展開させる必要がある。
方形状布類を四角形に展開する作業を作業員が行う場合、作業に多大な時間と労力が必要であるため、近年では、この作業を自動で行う展開装置によって行われている。 A large amount of sheets are used in hotels and hospitals, and the used sheets are generally washed and ironed in a laundry factory and used again in hotels and hospitals.
In a laundry factory, a rectangular cloth having a relatively large size such as a sheet is washed and then pressed by a press machine or folded by a folding machine. In order to supply rectangular fabrics to these processing apparatuses, it is necessary to develop the rectangular fabrics into a square shape in advance.
When a worker performs an operation of expanding a rectangular cloth into a quadrangle, a great amount of time and labor is required for the operation, and in recent years, this operation is performed by an expansion device that automatically performs this operation.

特許文献１に記載された従来の展開装置は、概略つぎのように構成されている。
方形状布類の一辺を横行チャックでつかんでベルトコンベア上に引きづり込み、そのベルトコンベアを駆動して方形状布類を装置前面に垂れ下がらせ、別の伸展チャックで方形状布類の幅方向両端をつかんで引っ張って吊下げる。この状態から方形状布類を装置内に引き込みかつ排出していくため、吊下げ状態の方形状布類の上縁をつかませ、かつ下縁を下向きにエアー吸引して垂みや皺のない状態にする。このための吸引機構として、ブロワー１６２や整形ダクト１６５を備えている。そして、方形状布類を展開装置内部に向け移動させバキュームコンベアに載せて、排出方向に搬出していく。 The conventional deployment device described in Patent Document 1 is generally configured as follows.
Grab one side of the square cloth with the traverse chuck and pull it onto the belt conveyor, drive the belt conveyor to hang the square cloth down the front of the device, and use another extension chuck to width the square cloth Hold both ends in the direction and hang by pulling. In order to draw and discharge the rectangular cloth from this state into the device, the upper edge of the suspended rectangular cloth is grasped, and the lower edge is air-sucked downward to prevent dripping or wrinkles. To. As a suction mechanism for this purpose, a blower 162 and a shaping duct 165 are provided. Then, the rectangular cloth is moved toward the inside of the developing device, placed on the vacuum conveyor, and carried out in the discharging direction.

図１０に基づき、上記吸引機構の従来例を説明する。Ｐ１は方形状布類Ｙ（点線図示）が受渡装置１５１で保持された初期位置を示している。このときの方形状布類Ｙは展開装置前面で垂れ下がっている。この状態で整形ダクト１６５内の空気を吸引すると、方形状布類Ｙは整形ダクト１６５の前面板１６４を乗り越えて整形ダクト１６５内に垂れ込む。この状態が符号Ｐ２で示す状態であり、更にブロワ１６２で整形ダクト１６５内の空気を吸引すると、方形状布類Ｙは縦方向に延び、皺のない状態となる。   A conventional example of the suction mechanism will be described with reference to FIG. P <b> 1 indicates an initial position where the rectangular cloth Y (shown by a dotted line) is held by the delivery device 151. The rectangular cloth Y at this time hangs down on the front surface of the developing device. When air in the shaping duct 165 is sucked in this state, the rectangular cloth Y gets over the front plate 164 of the shaping duct 165 and hangs into the shaping duct 165. This state is indicated by reference numeral P2, and when the air in the shaping duct 165 is further sucked by the blower 162, the rectangular cloth Y extends in the vertical direction and is free of wrinkles.

この後、受渡装置１５１を後退させて方形状布類Ｙをバキュームコンベア１６０に乗り移らせる。バキュームコンベア１６０に乗り移った方形状布類Ｙは、バキュームコンベア１６０の駆動により排出コンベア１７０の方向に移送され、排出コンベア１７０から、方形状布類展開装置Ａの後方に設置された次工程の処理装置（図示せず）に供給される。   Thereafter, the delivery device 151 is moved backward to transfer the rectangular cloth Y onto the vacuum conveyor 160. The rectangular cloth Y transferred to the vacuum conveyor 160 is transferred in the direction of the discharge conveyor 170 by driving the vacuum conveyor 160, and is processed from the discharge conveyor 170 at the rear of the rectangular cloth unfolding apparatus A. Supplied to a device (not shown).

しかるに上記従来技術の吸引装置では、つぎの問題がある。
方形状布類Ｙを整形ダクト１６５に落とし込むには、ブロワー１６２による吸引力を使うが、この吸引だけではうまく方形状布類Ｙが整形ダクト１６５に入らないときがある。とくに、方形状布類Ｙが幅広くなると、整形ダクト１６５の前面板１６４との摩擦抵抗も大きくなるので、垂れ込みが円滑にいかない傾向が強くなる。
しかるに、方形状布類Ｙが整形ダクト１６５に入らないと次工程に移行できないので、生産能率が低下する。 However, the prior art suction device has the following problems.
In order to drop the square-shaped cloth Y into the shaping duct 165, the suction force by the blower 162 is used. However, there is a case where the rectangular cloth Y does not enter the shaping duct 165 well only by this suction. In particular, when the rectangular cloth Y is widened, the frictional resistance between the shaping duct 165 and the front plate 164 is increased, so that the tendency for the sag not to go smoothly increases.
However, if the rectangular cloth Y does not enter the shaping duct 165, it cannot move to the next process, so that the production efficiency is lowered.

The discharge process is performed by driving the vacuum conveyor 60 and the discharge conveyor 70, and discharges the rectangular cloth Y developed in a square shape to the next process apparatus installed at the rear.

つぎに、受渡し工程を実行する各装置を詳細に説明する。
前記受渡機構５０は、方形状布類Ｙの上縁部Ｙｂを伸展チャック40R,40Lから受け取って、バキュームコンベア６０に受け渡すものである。
図１に示すように、受渡機構５０は、積載コンベア１１の下方に設けられており、吸着ボックス５１と、吸着ボックス５１を前後方向に移動させる駆動装置５２から構成されている。吸着ボックス５１は、左右方向には積載コンベア１１と同程度の長さを有している。また、その上面には吸引用小孔が形成されており、適宜の吸引機で吸着ボックス５１内の空気を吸引することで、方形状布類Ｙの上縁部Ｙｂを吸着することができるようになっている。 Next, each device that performs the delivery process will be described in detail.
The delivery mechanism 50 receives the upper edge Yb of the rectangular fabric Y from the extension chucks 40R and 40L and delivers it to the vacuum conveyor 60.
As shown in FIG. 1, the delivery mechanism 50 is provided below the stacking conveyor 11 and includes a suction box 51 and a driving device 52 that moves the suction box 51 in the front-rear direction. The suction box 51 has the same length as the stacking conveyor 11 in the left-right direction. Further, a small hole for suction is formed on the upper surface, and the upper edge Yb of the rectangular cloth Y can be sucked by sucking the air in the suction box 51 with an appropriate suction machine. It has become.

バキュームコンベア６０は、受渡機構５０から方形状布部Ｙの縁部Ｙｂを受け取り、方形状布部Ｙを排出コンベア７０へ移送するものである。
図１に示すように、バキュームコンベア６０は、受渡機構５０の下方に設けられている。バキュームコンベア６０の表面には多数の小孔が設けられており、その小孔に負圧を作用させるための吸引ダクト６１が接続されている。 The vacuum conveyor 60 receives the edge Yb of the rectangular cloth part Y from the delivery mechanism 50 and transfers the rectangular cloth part Y to the discharge conveyor 70.
As shown in FIG. 1, the vacuum conveyor 60 is provided below the delivery mechanism 50. A large number of small holes are provided on the surface of the vacuum conveyor 60, and a suction duct 61 for applying a negative pressure to the small holes is connected.

さらに、皺取り工程を実行する装置を詳述する。
前記吸引ダクト６１の前方には、受渡し工程で使用する整形ダクト６５が設けられている。この整形ダクト６５は吸引ダクト６１の壁面とその前方に立設された前面壁６４とで構成されている。 Furthermore, the apparatus which performs a scraping process is explained in full detail.
In front of the suction duct 61, a shaping duct 65 used in the delivery process is provided. The shaping duct 65 includes a wall surface of the suction duct 61 and a front wall 64 standing in front of the suction duct 61.

吸引ダクト６１と整形ダクト６５には共通の空気吸引機構が接続されている。
この空気吸引機構は、ブロワー６２と流路切換室６６とからなる。流路切換室６６には開口６６ａと開口６６ｂが形成され、その間をダンパ６７が揺動して開口６６ａ，６６ｂを開閉するようになっている。 A common air suction mechanism is connected to the suction duct 61 and the shaping duct 65.
This air suction mechanism includes a blower 62 and a flow path switching chamber 66. An opening 66a and an opening 66b are formed in the flow path switching chamber 66, and a damper 67 swings between them to open and close the openings 66a and 66b.

ダンパ６７が開口６６ｂを閉じると開口６６ａが開いて吸引ダクト６１に連通して空気を吸引する。この場合、バキュームコンベア６０上の布類がコンベア上に吸引された状態でコンベア搬送される。
ダンパ６７が開口６６ａを閉じると開口６６ｂが開いて整形ダクト６５に連通して空気を吸引する。この場合、伸展チャック40R，40Lと受渡機構５０で保持されて垂れ下がった布Ｙを下方に引っ張り、たくれた状態を矯正しかつ皺も取るようになっている。 When the damper 67 closes the opening 66b, the opening 66a opens and communicates with the suction duct 61 to suck air. In this case, the cloth on the vacuum conveyor 60 is conveyed by the conveyor while being sucked onto the conveyor.
When the damper 67 closes the opening 66a, the opening 66b opens and communicates with the shaping duct 65 to suck air. In this case, the sagging cloth Y held by the extension chucks 40R and 40L and the delivery mechanism 50 is pulled downward to correct the folded state and to remove wrinkles.

図１〜図３に示すように、本発明の展開装置にはエアー吹付け装置９０が設けられている。このエアー吹付け装置９０は圧縮エアーを噴射するパイプ９１で構成されている。パイプ９１にはコンプレッサ等の空圧源が接続されており、パイプ９１と空圧源との間にはバルブ（図示省略）が介装され、必要なタイミングでエアー噴射できるようになっている。   As shown in FIGS. 1-3, the expansion | deployment apparatus of this invention is provided with the air spraying apparatus 90. As shown in FIG. The air spraying device 90 is constituted by a pipe 91 that injects compressed air. An air pressure source such as a compressor is connected to the pipe 91, and a valve (not shown) is interposed between the pipe 91 and the air pressure source so that air can be injected at a necessary timing.

図１に示すように、前記パイプ９１には噴射孔９２が適数個形成している。この噴射孔９２からエアー噴射する領域は、受渡機構５０から吊下げられている方形状布類Ｙにおける整形ダクト６５の直近上方である。このように、整形ダクトの直近上方を狙ってエアーを吹き付けるので方形状布類Ｙが整形ダクト６５内に押し込みやすくなる。   As shown in FIG. 1, an appropriate number of injection holes 92 are formed in the pipe 91. The region where air is injected from the injection hole 92 is immediately above the shaping duct 65 in the rectangular cloth Y suspended from the delivery mechanism 50. In this way, air is blown toward the upper part of the shaping duct so that the rectangular cloth Y can be easily pushed into the shaping duct 65.

また図２および図３に示すように、エアー噴射する領域は方形状布類Ｙにおいて幅方向に離れた２ヵ所である。このように方形状布類Ｙの幅方向に離れた２ヵ所にエアーを吹き付けるので、方形状布類Ｙの寸法が大きくても整形ダクト６５内に押し込みやすくなる。   Moreover, as shown in FIG. 2 and FIG. 3, the area | region which injects air is two places away in the width direction in the square-shaped cloth Y. As shown in FIG. As described above, air is blown to two places separated in the width direction of the rectangular cloth Y, so that the rectangular cloth Y can be easily pushed into the shaping duct 65 even if the dimension of the rectangular cloth Y is large.

次に、皺取り工程および受渡し工程の詳細を図４〜図８に基づき説明する。
（１）図４は伸展機構である伸展チャック40R,40Lで方形状布類Ｙの両端部を保持し、かつ上縁部Ｙｂを吸着ボックス５１と固定部材である押付けバー５３との間で挾持している。このとき方形状布類Ｙは整形ダクト６５の前面壁６４より前方で吊下げられている。 Next, details of the scraping process and the delivery process will be described with reference to FIGS.
(1) FIG. 4 shows the extension mechanisms 40R and 40L, which are extension mechanisms, holding both ends of the rectangular cloth Y, and holding the upper edge Yb between the suction box 51 and the pressing bar 53, which is a fixing member. doing. At this time, the rectangular cloth Y is suspended from the front wall 64 of the shaping duct 65 in front.

（２）前記（１）の状態で、ダンパ６７は開口６６ａを閉じ開口６６ｂを開いているので、ブロワー６２は整形ダクト６５内のエアーを吸引している。これに加え図５に示すように、エアー吹付け装置９０から方形状布類Ｙにエアーを噴射させて、方形状布類Ｙを整形ダクト６５内に押し込む。方形状布類の下方部分は整形ダクト６５内に吸引されて該ダクト内に入っていこうとするが、さらにエアー吹付け装置９０からのエアー噴射による風圧が加わって方形状布類Ｙの下方部分が整形ダクト６５上方に押し込まれる。 (2) In the state (1), the damper 67 closes the opening 66 a and opens the opening 66 b, so that the blower 62 sucks air in the shaping duct 65. In addition to this, as shown in FIG. 5, air is jetted from the air blowing device 90 to the rectangular cloth Y, and the rectangular cloth Y is pushed into the shaping duct 65. The lower part of the rectangular cloth Y is sucked into the shaping duct 65 and tries to enter the duct. However, the lower part of the rectangular cloth Y is added with the wind pressure by the air jet from the air blowing device 90. Is pushed above the shaping duct 65.

（３）図６に示すように、方形状布類Ｙの下方部分は整形ダクト６５内に入り込んでいるので、そのままブロワー６２でエアー吸引すると、方形状布類Ｙが下方に引っ張られて、弛みや皺がとれる。これが、皺取り工程である。 (3) As shown in FIG. 6, since the lower part of the rectangular cloth Y enters the shaping duct 65, if the air is sucked by the blower 62 as it is, the rectangular cloth Y is pulled downward and loosened. I can get a habit. This is the wrinkle removal process.

（４）ついで、伸展チャック40R,40Lを解放し、図７に示すように方形状布類Ｙの上縁部Ｙｂを吸着した吸引ボックス５１が後方に移動すると、その方形状布類Ｙはバキュームコンベア６０に接触する。この状態に合わせダンパ６７が開口６６ｂを閉じ開口６６ａを開くと、吸引ダクト６１内の空気がブロワ６２で吸引され、バキュームコンベア６０には負圧が作用する。そうすると、方形状布類Ｙはバキュームコンベア６０の吸引により保持されて、受渡機構５０からバキュームコンベア６０に乗り移る。 (4) Next, when the extension chucks 40R and 40L are released and the suction box 51 adsorbing the upper edge Yb of the rectangular cloth Y moves backward as shown in FIG. 7, the rectangular cloth Y is vacuumed. Contact the conveyor 60. When the damper 67 closes the opening 66b and opens the opening 66a in accordance with this state, the air in the suction duct 61 is sucked by the blower 62, and a negative pressure acts on the vacuum conveyor 60. Then, the rectangular cloth Y is held by suction of the vacuum conveyor 60 and is transferred from the delivery mechanism 50 to the vacuum conveyor 60.

さらに、図８に示すようにバキュームコンベア６０が後方に駆動して、乗り移った方形状布類Ｙを排出コンベア７０に移送する。排出コンベア７０は、方形状に展開された方形状布類Ｙを後方に設置される次工程の処理装置に供給する。   Further, as shown in FIG. 8, the vacuum conveyor 60 is driven rearward to transfer the transferred square cloth Y to the discharge conveyor 70. The discharge conveyor 70 supplies the square-shaped cloth Y developed in a square shape to the processing device of the next process installed behind.

（他の実施形態）
上記実施形態では、エアー噴射領域を左右方向に離れた２ヵ所としたが、３ヵ所以上でもよく１ヵ所でもよい。また、離れた領域に噴射する代わりに連続してつながった領域にエアー噴射してもよい。要するに、方形状布類Ｙを整形ダクト６５内に確実にたくし込むことができればよい。 (Other embodiments)
In the above-described embodiment, the air injection area is two places separated in the left-right direction, but may be three or more places or one place. Further, instead of spraying to a remote area, air may be sprayed to a continuously connected area. In short, it is only necessary that the rectangular cloth Y can be reliably tucked into the shaping duct 65.

上記実施形態では、方形状布類Ｙが伸展チャック40R,40Lおよび吸着ボックス５１で保持されている状態でエアー吹付け装置９０からエアー噴射して整形ダクト６５内にたくし込まれたが、もっと後のタイミングであってもよい。
たとえば、方形状布類Ｙが吸着ボックス５１で展開装置内に引き込まれバキュームコンベア６０に吸着させた状態になったときに、エアー吹付け装置９０がエアー噴射して整形ダクト６５内にたくし込まれるようにしてもよい。このタイミングでのたくし込みは縦長さの大きいシーツに特に有効である。 In the above embodiment, the rectangular cloth Y is held by the extension chucks 40R and 40L and the suction box 51, and is blown into the shaping duct 65 by air injection from the air blowing device 90. It may be the timing.
For example, when the rectangular cloth Y is drawn into the developing device by the suction box 51 and is sucked by the vacuum conveyor 60, the air blowing device 90 jets air into the shaping duct 65. You may do it. The convolution at this timing is particularly effective for sheets having a large vertical length.

特許請求の範囲における「展開装置の前面で保持されている方形状布類」とは、展開装置の前面のみで方形状布類が保持されている場合だけでなく、方形状布類の上方部分が内部に引き込まれても下方部分が前面に残されている場合も含む意味である。   The term “square cloth held on the front surface of the deployment device” in the claims means not only the case where the square fabric is held only on the front surface of the deployment device, but also the upper part of the square fabric. This includes the case where the lower part is left on the front surface even if the is drawn into the interior.

（各実施形態の長所）
以上のように、本発明の各実施形態によれば、展開装置前面で吊下げられている方形状布類Ｙの下方部分が整形ダクト６５内に吸引されて該ダクト内に入っていこうとするが、エアー吹付け装置９０からのエアー噴射による風圧によって方形状布類Ｙの下方部分が整形ダクト６５上方に強く押し込まれる。このため、方形状布類Ｙに整形ダクト６５内の吸引力が作用しやすくなって、円滑かつ確実に方形状布類Ｙを次工程装置に送り込める。 (Advantages of each embodiment)
As described above, according to each embodiment of the present invention, the lower part of the rectangular cloth Y suspended from the front surface of the developing device is sucked into the shaping duct 65 and attempts to enter the duct. However, the lower part of the rectangular cloth Y is strongly pushed above the shaping duct 65 by the wind pressure generated by the air jet from the air blowing device 90. For this reason, the suction force in the shaping duct 65 easily acts on the rectangular cloth Y, and the rectangular cloth Y can be smoothly and reliably fed to the next process apparatus.
