The recovery system includes a cyclone-type separation device, an aspirator (hereinafter, referred to as an air flow generation unit) which is connected to the separation device and generates a swirl flow inside the separation device by suctioning air. The separating device comprises two cyclone devices connected in series, in which the lint is separated from air and dust. In the second cyclone device, dust is separated.
　より詳細には、第１のサイクロン装置は、その内部に旋回流が発生する容器と、容器内に空気が流入する流入口と、容器内から空気が排出される排気口と、容器の底部に配置され、糸屑が排出される開口とを有する。開口は、通常、バルブによって閉止されている。気流生成部の動作によって容器の内部空間に旋回流が発生すると、排気口から空気及びダストが排出され、それらと分離された糸屑が容器の底部近傍に溜まる。上記バルブを定期的に開けることで、上記開口を介して糸屑を外部へ排出することが可能になる。 More specifically, the first cyclone device has a container in which a swirl flow is generated, an inlet through which air flows into the container, an exhaust port through which the air is discharged from the container, and a bottom of the container. And an opening through which the lint is discharged. The opening is usually closed by a valve. When a swirling flow is generated in the internal space of the container by the operation of the air flow generation unit, air and dust are discharged from the exhaust port, and thread waste separated therefrom is accumulated near the bottom of the container.

　上記気流生成部の動作中は、流入口から排気口に向かって空気が吸引されている。このため、第１のサイクロン装置において、仮に気流生成部の動作中にバルブを開けると、外部の空気が上記開口を介して容器内に吸い込まれ、溜まった糸屑が吹き上げられて第２のサイクロン装置へ流れ込む等のおそれがある。したがって、容器内から糸屑を排出する際には、気流生成部の動作を停止させる必要がある。このため、例えば、気流生成部を常に動作させて糸屑の分離を行いつつ、溜まった糸屑を任意のタイミングで排出したい場合に、上述した回収システムでは、それができないという問題点がある。 During the operation of the air flow generation unit, air is drawn from the inlet toward the outlet. For this reason, in the first cyclone device, if the valve is opened temporarily during operation of the air flow generation unit, the external air is sucked into the container through the opening, and the accumulated lint is blown up and the second cyclone is generated. There is a risk of flowing into the device. Therefore, when discharging thread waste from the container, it is necessary to stop the operation of the air flow generation unit. For this reason, for example, when it is desired to discharge accumulated thread waste at an arbitrary timing while always operating the air flow generation unit to separate thread waste, there is a problem that the above-described recovery system can not do so.
　本発明の目的は、気流生成部が動作中の場合でも、繊維屑の外部への排出を可能にすることである。 An object of the present invention is to enable the discharge of fiber waste to the outside even when the air flow generation unit is in operation.
　第１の発明の繊維機械は、糸を処理する糸処理ユニットと、前記糸処理ユニットの糸処理に伴い発生する繊維屑を空気と分離する繊維屑分離部と、前記繊維屑分離部と接続され、前記繊維屑分離部の内部空間において所定の軸方向周りに旋回する旋回流を発生させる気流生成部と、前記繊維屑分離部によって分離された繊維屑を回収する繊維屑回収部と、を備える繊維機械であって、前記繊維屑分離部は、内周面を有する周壁と、前記周壁の前記軸方向の途中部に形成され、繊維屑を含んだ空気が流入する流入口と、前記流入口よりも前記軸方向の前記一方側に形成され、空気が排出される排気口と、前記流入口よりも前記軸方向の他方側に形成され、繊維屑が排出される繊維屑排出口と、を有し、前記周壁の前記軸方向に直交する断面の内径は、前記軸方向において前記流入口から前記繊維屑排出口に向かうにつれて大きくなっており、前記繊維屑回収部は、外部に対して密閉された密閉状態と外部に対して開放された開放状態との間で状態変更が可能であり、前記繊維屑回収部の内部空間は、前記繊維屑排出口を介して、前記繊維屑分離部の内部空間と連通可能に構成されており、前記繊維屑分離部の内部空間と前記繊維屑回収部の内部空間を連通させる連通位置と、前記繊維屑分離部の内部空間と前記繊維屑回収部の内部空間を遮断する遮断位置との間で移動可能な、シャッタを備えることを特徴とするものである。 A textile machine according to a first aspect of the present invention is connected to a yarn processing unit for processing yarn, a fiber separation part for separating fiber waste generated from the yarn processing of the yarn processing unit from the air, and the fiber separation part An air flow generation unit that generates a swirling flow that turns around a predetermined axial direction in an internal space of the fiber waste separation unit; and a fiber waste collection unit that collects fiber waste separated by the fiber separation unit. In the textile machine, the fiber waste separation part is a peripheral wall having an inner circumferential surface, an inlet formed in an axial middle part of the peripheral wall, into which air containing fiber waste flows, and the inlet An exhaust port formed on the one side in the axial direction and discharging air, and a fiber waste discharge port formed on the other side in the axial direction from the inflow port and discharging fiber wastes; Of the cross section orthogonal to the axial direction of the peripheral wall The diameter increases in the axial direction from the inflow port toward the fiber waste outlet, and the fiber waste recovery part is in a closed state sealed from the outside and an open state opened to the outside And the internal space of the fiber waste collection unit can be communicated with the internal space of the fiber separation part via the fiber discharge port, and the fiber waste can be changed. Movable between a communication position where the internal space of the separation unit and the internal space of the fiber waste collection part are in communication, and a blocking position where the internal space of the fiber waste separation part and the inner space of the fiber waste collection part are isolated , And a shutter.
　繊維屑分離部の内部空間では、気流生成部の動作によって旋回流が発生する。繊維屑を含んだ空気が、流入口を介して繊維屑分離部に流入すると、旋回流によって、繊維屑が周壁に沿って渦を巻くように移動し、繊維屑に対して遠心力が作用する。本発明では、周壁の内径は、軸方向において、流入口から繊維屑排出口に向かうにつれて大きくなっている。これにより、流入口から流入した繊維屑に作用する遠心力は、周壁の内周面に垂直な成分と平行な成分とに分解される。この平行な成分が、軸方向における他方側、すなわち繊維屑排出口側を向いているため、繊維屑は、内周面に沿って、内径が大きくなる側、すなわち繊維屑排出口側に案内される。したがって、流入口から流入した繊維屑が排気口側に吸い寄せられることを防ぎ、且つ、繊維屑を繊維屑排出口側に確実に移動させることができる。 In the internal space of the fiber waste separation unit, a swirling flow is generated by the operation of the air flow generation unit. When air containing fiber waste flows into the fiber separation part through the inlet, the swirling flow causes the fiber waste to move in a swirling manner along the peripheral wall, and a centrifugal force acts on the fiber waste. . In the present invention, the inner diameter of the peripheral wall increases in the axial direction from the inflow port toward the fiber waste discharge port. Thereby, the centrifugal force acting on the fiber debris flowing in from the inflow port is decomposed into a component perpendicular to the inner circumferential surface of the peripheral wall and a component parallel thereto. Since this parallel component is directed to the other side in the axial direction, that is, the fiber waste outlet side, the fiber waste is guided along the inner circumferential surface to the side with the larger inner diameter, that is, the fiber waste outlet side Ru. Therefore, it is possible to prevent the fiber waste that has flowed in from the inflow port from being drawn to the outlet side, and to reliably move the fiber waste to the fiber waste outlet side.
　また、本発明では、繊維屑回収部が、密閉状態と開放状態との間で状態変更可能である。さらに、繊維屑回収部の内部空間と繊維屑分離部の内部空間が連通可能に構成されており、シャッタが、上記２つの内部空間を連通させる連通位置と、これらを遮断する遮断位置との間で移動可能である。繊維屑回収部が密閉状態にあり、且つ、シャッタが連通位置にあるときには、繊維屑回収部に繊維屑が回収される。一方、シャッタが遮断位置にあるときには、気流生成部の動作中に繊維屑回収部を開放状態にしても、外部から繊維屑分離部に空気が流入して繊維屑が逆流することを防止できるので、繊維屑回収部を開放状態にして、回収された繊維屑を外部へ排出できる。したがって、気流生成部が動作中の場合でも、繊維屑の外部への排出を可能にすることができる。以上より、繊維屑回収部において繊維屑を確実に回収し、繊維屑回収部内に蓄積している繊維屑を任意のタイミングで外部へ排出することができる。 Further, in the present invention, the fiber waste recovery unit can be changed in state between the closed state and the open state. Furthermore, the internal space of the fiber waste collection part and the internal space of the fiber separation part can communicate with each other, and between the communication position where the shutter connects the two internal spaces and the blocking position that blocks them. It is movable with When the fiber debris recovery unit is in a closed state and the shutter is in the communication position, the fiber debris is recovered by the fiber debris recovery unit. On the other hand, when the shutter is in the blocking position, air can be prevented from flowing from the outside into the fiber separating portion and the fiber backflow being prevented even if the fiber collecting portion is opened during the operation of the air flow generating unit. The waste fiber recovery part can be opened to discharge the collected fiber waste to the outside. Therefore, even when the air flow generation unit is in operation, the fiber debris can be discharged to the outside. As described above, the fiber waste can be reliably collected in the fiber waste collection unit, and the fiber waste accumulated in the fiber collection unit can be discharged to the outside at an arbitrary timing.
　第２の発明の繊維機械は、前記第１の発明において、前記軸方向は、鉛直方向であり、
　前記繊維屑排出口は、前記流入口の下方に配置されていることを特徴とするものである。 In the textile machine of the second invention according to the first invention, the axial direction is a vertical direction,
The fiber waste outlet is disposed below the inlet.
　本発明では、鉛直方向において流入口から繊維屑排出口へ向かう側に重力が作用するので、繊維屑をより確実に繊維屑排出口側に移動させることができる。 In the present invention, since gravity acts on the side from the inflow port to the fiber waste outlet in the vertical direction, the fiber waste can be more reliably moved to the fiber waste outlet side.
　第３の発明の繊維機械は、前記第１又は第２の発明において、前記周壁の前記内周面全体が、前記軸方向における前記一方側から前記他方側に向かうにつれて前記周壁の前記内径が大きくなるテーパ面であることを特徴とするものである。 In a textile machine according to a third aspect of the present invention, in the first or second aspect, the inner diameter of the peripheral wall becomes larger as the entire inner peripheral surface of the peripheral wall goes from the one side to the other side in the axial direction And a tapered surface.
　本発明では、周壁の内周面全体がテーパ面になっているため、軸方向における周壁の内周面全体に渡って、繊維屑は、内周面に沿って、内径が大きくなる側、すなわち繊維屑排出口側に案内される。従って、流入口から流入した繊維屑が排気口側に吸い寄せられることを確実に防ぎ、且つ、繊維屑を繊維屑排出口側により確実且つスムーズに移動させることができる。 In the present invention, since the entire inner peripheral surface of the peripheral wall is a tapered surface, the fiber waste has a large inner diameter along the inner peripheral surface along the entire inner peripheral surface of the peripheral wall in the axial direction, that is, It is guided to the fiber waste outlet side. Therefore, it is possible to reliably prevent the fiber debris that has flowed in from the inflow port from being drawn to the outlet side, and to move the fiber debris more reliably and smoothly to the fiber debris outlet side.
　第４の発明の繊維機械は、前記第１～第３のいずれかの発明において、前記繊維屑排出口は、前記繊維屑分離部の前記軸方向における前記他方側の端面の全域に亘って形成されていることを特徴とするものである。 In a textile machine according to a fourth aspect of the present invention, in the first aspect to the third aspect, the fiber waste outlet is formed over the entire end face of the other side in the axial direction of the fiber waste separation part. It is characterized by being.
　本発明では、繊維屑排出口が、繊維屑分離部の軸方向における他方側の端面の全域に亘って形成されているため、排出される繊維屑が繊維屑排出口に引っかかりにくくなる。また、繊維屑排出口の面積を大きくすることができる。したがって、繊維屑を繊維屑排出口から確実に排出することができる。 In the present invention, since the fiber waste discharge port is formed over the entire area of the other end face in the axial direction of the fiber waste separation portion, the fiber waste discharged is less likely to be caught by the fiber waste discharge port. In addition, the area of the fiber waste outlet can be increased. Therefore, the fiber waste can be reliably discharged from the fiber waste discharge port.
　第５の発明の繊維機械は、前記第４の発明において、前記シャッタは、前記繊維屑排出口を開閉可能、且つ、少なくとも前記軸方向に移動可能に構成されていることを特徴とするものである。 A textile machine according to a fifth invention is characterized in that, in the fourth invention, the shutter is configured to be capable of opening and closing the fiber waste outlet and movable at least in the axial direction. is there.
　繊維屑分離部の軸方向における他方側の端面の全域に亘って繊維屑排出口が形成されている構成においては、繊維屑排出口の面積が大きくなりうる。このため、例えば、繊維屑排出口が形成されている面に対してシャッタを平行移動させて繊維屑排出口を開閉する構成になっていると、繊維屑排出口を完全に開放又は閉止するために必要なシャッタの移動距離が長くなり、繊維屑排出口の開閉に時間がかかるおそれがある。本発明では、シャッタが繊維屑排出口を開閉可能、且つ、少なくとも軸方向に移動可能であるため、繊維屑排出口を完全に開放又は閉止するために必要なシャッタの移動距離を短くすることができる。したがって、繊維屑排出口の開閉にかかる時間を短くすることができる。 In the configuration in which the fiber waste discharge port is formed over the entire end face on the other side in the axial direction of the fiber waste separation portion, the area of the fiber waste discharge port may be large. Therefore, for example, when the shutter is moved in parallel to the surface on which the fiber waste outlet is formed to open and close the fiber outlet, the fiber waste outlet is completely opened or closed. The moving distance of the shutter required for the above becomes long, and it may take time to open and close the fiber waste discharge port. In the present invention, since the shutter is capable of opening and closing the fiber waste outlet and is movable at least in the axial direction, the movement distance of the shutter necessary for completely opening or closing the fiber waste outlet can be shortened. it can. Therefore, the time taken to open and close the fiber waste outlet can be shortened.
　第６の発明の繊維機械は、前記第１～第３のいずれかの発明において、前記繊維屑排出口は、前記周壁に形成されていることを特徴とするものである。 A textile machine according to a sixth invention is characterized in that, in any one of the first to third inventions, the fiber waste outlet is formed in the peripheral wall.
　本発明では、繊維屑排出口が、周壁に形成されている。したがって、繊維屑排出口が繊維屑分離部の軸方向における他方側の端面の全域に亘って形成されている場合と比べて、繊維屑排出口を小さくすることができる。これにより、シャッタが繊維屑排出口を開閉可能に構成することで、シャッタのサイズを小さくすることができる。 In the present invention, the fiber waste outlet is formed in the peripheral wall. Therefore, the fiber waste discharge port can be made smaller than in the case where the fiber waste discharge port is formed over the entire area of the other end face in the axial direction of the fiber waste separation portion. Thus, the size of the shutter can be reduced by configuring the shutter to open and close the fiber waste outlet.
　第７の発明の繊維機械は、前記第６の発明において、前記繊維屑分離部は、前記軸方向に直交する断面において、前記繊維屑排出口から、前記周壁の前記内周面の、前記繊維屑排出口の形成位置における接線方向に延びる管部を有することを特徴とするものである。 In the textile machine according to a seventh aspect of the present invention, in the sixth aspect, the fiber waste separation part has the fibers of the inner peripheral surface of the peripheral wall from the fiber waste discharge port in a cross section orthogonal to the axial direction. It is characterized by having a tube portion extending in the tangential direction at the formation position of the waste discharge port.
　本発明では、管部が、内周面の、繊維屑排出口の形成位置における接線方向に延びている。これにより、空気と分離された繊維屑が、繊維屑排出口を通って繊維屑分離部から出た後、管部に沿って滑らかに繊維屑回収部側へ流れる。したがって、繊維屑をスムーズに排出することができる。 In the present invention, the tube portion extends in the tangential direction at the formation position of the fiber waste outlet on the inner circumferential surface. Thus, the fiber waste separated from the air flows out from the fiber waste separation part through the fiber waste outlet, and then flows smoothly along the pipe part to the fiber waste collection part side. Therefore, fiber waste can be discharged smoothly.
　第８の発明の繊維機械は、前記第６又は第７の発明において、前記軸方向は、鉛直方向であり、前記繊維屑分離部は、前記軸方向の前記他方側が下方側となるように構成されており、前記周壁の下端を塞ぐ底部を有し、前記繊維屑排出口は、前記周壁の下端部に形成されていることを特徴とするものである。 In the textile machine according to an eighth aspect of the present invention, in the sixth or seventh aspect, the axial direction is a vertical direction, and the fiber waste separation portion is configured such that the other side in the axial direction is a lower side. It has a bottom part which closes the lower end of the above-mentioned peripheral wall, and the above-mentioned textiles waste outlet is formed in the lower end part of the above-mentioned peripheral wall.
　繊維屑排出口が周壁の軸方向における途中部に形成されていると、繊維屑が繊維屑排出口から排出され損なった場合、繊維屑が重力によって落下し、繊維屑分離部内において底部付近に溜まるおそれがある。本発明では、繊維屑排出口が周壁の下端部に形成されているため、繊維屑が繊維屑排出口から排出され損なった場合でも、繊維屑は、旋回して再び繊維屑排出口付近に移動する。したがって、繊維屑が底部付近に溜まることを抑制できる。 When the fiber waste outlet is formed in the middle of the peripheral wall in the axial direction, when the fiber waste is discharged from the fiber waste outlet and damaged, the fiber waste falls due to gravity and is accumulated near the bottom in the fiber waste separation part There is a fear. In the present invention, since the fiber waste outlet is formed at the lower end of the peripheral wall, even if the fiber waste is discharged from the fiber waste outlet and damaged, the fiber waste swirls and moves to the vicinity of the fiber waste outlet again. Do. Therefore, it can control that textile waste accumulates near the bottom.
　第９の発明の繊維機械は、前記第１～第８のいずれかの発明において、その一端部が前記糸処理ユニットと接続され、その他端部が前記流入口を介して前記繊維屑分離部と接続された第１ダクトと、その一端部が前記繊維屑排出口を介して前記繊維屑分離部と接続され、その他端部が前記第１ダクトの途中部と接続された第２ダクトと、を備え、前記第２ダクトの途中部には、開口が形成されており、前記繊維屑回収部の内部空間は、前記開口を介して前記第２ダクトと連通することで繊維屑を回収可能に構成されており、前記シャッタは、前記繊維屑回収部の内部空間と前記第２ダクトを連通させる連通位置と、前記繊維屑回収部の内部空間と前記第２ダクトを遮断する遮断位置との間で移動可能であることを特徴とするものである。 The textile machine according to a ninth aspect of the present invention is the textile machine according to any one of the first to eighth aspects, wherein one end is connected to the yarn processing unit, and the other end is connected to the fiber waste separating portion through the inflow port. A connected first duct, and a second duct whose one end is connected to the fiber waste separation part via the fiber waste outlet and whose other end is connected to an intermediate part of the first duct; An opening is formed in an intermediate portion of the second duct, and the internal space of the fiber waste collection part is configured to be able to collect fiber waste by communicating with the second duct via the opening. The shutter is located between a communication position for communicating the internal space of the fiber waste recovery part with the second duct, and a blocking position for closing the internal space of the fiber waste recovery part and the second duct. It is characterized by being movable.
　繊維屑回収部に回収された繊維屑を外部へ排出するときには、繊維屑が繊維屑分離部側へ逆流することを防ぐため、シャッタを遮断位置に位置させる必要がある。ここで、シャッタを遮断位置に位置させつつ気流生成部を動作させている間は、繊維屑分離部で分離された繊維屑が繊維屑回収部に回収されずに、繊維屑分離部内に滞留しうる。すると、繊維屑排出口の位置や大きさ等によっては、繊維屑が繊維屑排出口の近傍に溜まって繊維屑排出口が詰まるおそれがある。 When the fiber waste collected in the fiber waste collection unit is discharged to the outside, the shutter needs to be positioned at the blocking position in order to prevent the fiber waste from flowing back to the fiber separation part side. Here, while the air flow generation unit is operated while the shutter is positioned at the blocking position, the fiber waste separated in the fiber waste separation part is retained in the fiber waste separation part without being collected in the fiber waste collection part. sell. Then, depending on the position and size of the fiber waste outlet, the fiber waste may be accumulated in the vicinity of the fiber outlet and the fiber outlet may be clogged.
　本発明では、流入口を介して繊維屑分離部と接続された第１ダクトの途中部に、繊維屑排出口を介して繊維屑分離部と接続された第２ダクトが接続されている。これにより、繊維屑排出口を通って繊維屑分離部から出た繊維屑が、第２ダクト及び第１ダクトを通り、流入口を介して再び繊維屑分離部に戻る、還流経路が形成される。また、シャッタは、繊維屑回収部の内部空間と第２ダクトを連通させ、又は遮断するので、シャッタが遮断位置にある場合でも、上記還流経路が形成された状態を保つことができる。これにより、シャッタが連通位置にあるときには開口を介して繊維屑が回収され、シャッタが遮断位置にあるときには、繊維屑は還流経路を通って循環するため、繊維屑分離部内に繊維屑が滞留しにくくなる。したがって、繊維屑排出口が詰まることを防止することができる。 In the present invention, the second duct connected to the fiber waste separation part via the fiber waste outlet is connected to the middle part of the first duct connected to the fiber waste separation part via the inflow port. As a result, a fiber recirculation path is formed in which the fiber waste that has exited the fiber separation part through the fiber waste outlet passes through the second duct and the first duct and returns again to the fiber separation part via the inlet. . Further, the shutter connects or shuts off the internal space of the fiber waste collection portion and the second duct, so that the reflux path can be maintained even when the shutter is in the blocking position. As a result, when the shutter is in the communication position, the fiber waste is collected through the opening, and when the shutter is in the blocking position, the fiber waste circulates through the reflux path, so the fiber waste remains in the fiber waste separation portion. It becomes difficult. Therefore, clogging of the fiber waste outlet can be prevented.
　第１０の発明の繊維機械は、前記第１～第９のいずれかの発明において、前記シャッタを前記連通位置と前記遮断位置との間で移動させる駆動部と、前記駆動部を制御するシャッタ制御部と、を備え、前記シャッタ制御部は、前記シャッタが前記遮断位置に位置しており、且つ、前記繊維屑回収部が前記開放状態にあるときに、前記シャッタの前記遮断位置から前記連通位置への移動を禁止することを特徴とするものである。 A textile machine according to a tenth aspect of the present invention is the textile machine according to any one of the first to ninth aspects, wherein: a driving unit for moving the shutter between the communication position and the blocking position; and shutter control for controlling the driving unit And the shutter control unit is configured to communicate with the communication position from the blocking position of the shutter when the shutter is at the blocking position and the fiber waste collection unit is in the open state. It is characterized in that the movement to the
　本発明では、シャッタが遮断位置に位置しており、且つ、繊維屑回収部が開放状態にあるときに、シャッタ制御部によって、シャッタが遮断位置から連通位置に移動することが禁止される。したがって、気流生成部の動作中に、外部の空気が繊維屑排出口を通じて繊維屑分離部に流れ込んで繊維屑が逆流することを抑制できる。 In the present invention, the shutter control unit prohibits the shutter from moving from the blocking position to the communication position when the shutter is in the blocking position and the fiber waste collection unit is in the open state. Therefore, during the operation of the air flow generation unit, it is possible to prevent the external air from flowing into the fiber waste separation part through the fiber waste discharge port and causing backflow of the fiber waste.

It is characterized by prohibition.
　本発明では、繊維屑回収部が密閉状態であり、且つ、シャッタが連通位置に位置しているときに、回収制御部によって、繊維屑回収部が密閉状態から開放状態へ状態変更することが禁止される。したがって、気流生成部の動作中に、外部の空気が繊維屑排出口を通じて繊維屑分離部に流れ込んで繊維屑が逆流することを抑制できる。 In the present invention, it is prohibited to change the state of the fiber debris recovery unit from the closed state to the open state by the recovery control unit when the fiber debris recovery unit is in the closed state and the shutter is at the communication position.

　糸処理ユニットが糸処理を行っているときに、常に気流生成部が動作していても、本発明では、繊維屑排出口を塞ぐシャッタが設けられているため、繊維屑回収部に溜まった繊維屑を任意のタイミングで外部へ排出できる。したがって、繊維屑を外部へ排出する際に糸処理を停止させる必要がなく、生産効率の低下を防止することができる。 Even when the air flow generation unit is always operating when the yarn processing unit is performing yarn processing, in the present invention, since the shutter for closing the fiber waste outlet is provided, the fibers collected in the fiber waste collection unit Waste can be discharged to the outside at any time. Therefore, there is no need to stop the yarn processing when the fiber waste is discharged to the outside, and a decrease in production efficiency can be prevented.

（紡績ユニット）
　次に、紡績ユニット２の構成について、図３及び図４を用いて説明する。図３は、紡績ユニット２の概略的な側面図である。図４は、後述する空気紡績装置１２の内部構造を示す断面図である。 (Spinning unit)
Next, the configuration of the spinning unit 2 will be described using FIGS. 3 and 4. FIG. 3 is a schematic side view of the spinning unit 2. FIG. 4 is a cross-sectional view showing the internal structure of the air spinning device 12 described later.
　図３に示すように、紡績ユニット２は、繊維束Ｆ又は糸Ｙの走行方向（以下、単に糸走行方向とする）の上流側から下流側へ向かって順に配置された、ドラフト装置１１と、空気紡績装置１２と、糸貯留装置１３と、糸継装置１４と、巻取装置１５と、ユニット制御部２０（図２参照）等を備える。 As shown in FIG. 3, the spinning unit 2 includes a draft device 11 disposed in order from the upstream side to the downstream side in the traveling direction of the fiber bundle F or the yarn Y (hereinafter simply referred to as the yarn traveling direction); The air spinning device 12, the yarn storage device 13, the yarn joining device 14, the winding device 15, a unit control unit 20 (see FIG. 2) and the like are provided.
　ドラフト装置１１は、糸の原料となるスライバＳを、所定の太さとなるまで引き延ばして（ドラフトして）繊維束Ｆとするためのものである。ドラフト装置１１は、紡績ユニット２の下側部分、且つ、前側部分に配置されている。ドラフト装置１１は、糸走行方向の上流側から順に、バックローラ対２１と、サードローラ対２２と、ミドルローラ対２３と、フロントローラ対２４とを有する。ミドルローラ対２３を構成する２つのローラには、それぞれエプロンベルト２５が巻き掛けられている。なお、ドラフト装置１１の下方には、スライバＳを供給するスライバケース２６が配置されている。紡績ユニット２とスライバケース２６は、隔壁２７によって隔てられている。 The draft device 11 is for drafting the sliver S, which is a raw material of the yarn, to a predetermined thickness to obtain a fiber bundle F. The draft device 11 is disposed at the lower portion and the front portion of the spinning unit 2. The draft device 11 includes a back roller pair 21, a third roller pair 22, a middle roller pair 23, and a front roller pair 24 in order from the upstream side in the yarn traveling direction. An apron belt 25 is wound around each of two rollers constituting the middle roller pair 23. Below the draft device 11, a sliver case 26 for supplying the sliver S is disposed. The spinning unit 2 and the sliver case 26 are separated by a partition wall 27.
　空気紡績装置１２は、ドラフト装置１１から供給された繊維束Ｆに撚りを加えることで紡績し、糸Ｙを生成するためのものである。空気紡績装置１２は、ドラフト装置１１の後方（糸走行方向下流側）に配置されている。本実施形態では、空気紡績装置１２は、旋回空気流を利用して繊維束Ｆに撚りを加える。 The air spinning device 12 is for producing a yarn Y by spinning the fiber bundle F supplied from the draft device 11 by twisting it. The air spinning device 12 is disposed rearward of the draft device 11 (downstream in the yarn traveling direction). In the present embodiment, the pneumatic spinning device 12 twists the fiber bundle F using a swirling air flow.
　より詳細には、空気紡績装置１２は、図４に示すように、繊維案内部３１と、紡績室３２と、ノズルブロック３３と、中空ガイド軸体３４と、を有する。繊維案内部３１は、上流側のドラフト装置１１から供給された繊維束Ｆを、繊維導入路３１ａを介して紡績室３２内に案内する。ノズルブロック３３には、複数のノズル３３ａが、繊維束Ｆが走行する経路の周囲に形成されている。複数のノズル３３ａには、圧縮空気を供給するための空気圧送装置（不図示）が接続されている。ノズルブロック３３と中空ガイド軸体３４との間には、隙間３５が形成されている。ノズルブロック３３の内部には、隙間３５を介して紡績室３２と連通する減圧室３６が形成されている。減圧室３６には、ダクト３７（図３参照）の一端部が接続されている。さらに、ダクト３７の他端部には、後述するセクションダクト６３が接続されている（図３参照）。 More specifically, as shown in FIG. 4, the pneumatic spinning device 12 has a fiber guide portion 31, a spinning chamber 32, a nozzle block 33, and a hollow guide shaft 34. The fiber guiding portion 31 guides the fiber bundle F supplied from the draft device 11 on the upstream side into the spinning chamber 32 via the fiber introducing path 31a. In the nozzle block 33, a plurality of nozzles 33a are formed around the path along which the fiber bundle F travels. A pneumatic feed device (not shown) for supplying compressed air is connected to the plurality of nozzles 33a. A gap 35 is formed between the nozzle block 33 and the hollow guide shaft 34. In the inside of the nozzle block 33, a pressure reducing chamber 36 communicating with the spinning chamber 32 via a gap 35 is formed. One end of a duct 37 (see FIG. 3) is connected to the decompression chamber 36. Furthermore, a section duct 63 described later is connected to the other end of the duct 37 (see FIG. 3).
　ノズル３３ａから圧縮空気が噴射されることで、紡績室３２内に旋回空気流が発生する（図４のブロック矢印参照）。この旋回空気流によって、繊維束Ｆを構成する複数の繊維の各繊維端が反転されて旋回させられる（図４の二点鎖線参照）。中空ガイド軸体３４は、紡績室３２内から繊維通路３４ａを介して、生成された糸Ｙを空気紡績装置１２の外部に案内する。繊維束Ｆのうち、糸Ｙにならなかった繊維（すなわち、紡績前の繊維の屑）は、繊維屑Ｄとして、圧縮空気と共に紡績室３２から隙間３５を通って減圧室３６に流入し、ダクト３７内を通って、繊維屑回収システム４によって回収される。詳細については後述する。 By injecting compressed air from the nozzle 33a, a swirling air flow is generated in the spinning chamber 32 (see a block arrow in FIG. 4). By this swirling air flow, each fiber end of the plurality of fibers constituting the fiber bundle F is inverted and swirled (see the two-dot chain line in FIG. 4). The hollow guide shaft 34 guides the produced yarn Y to the outside of the air spinning device 12 from the inside of the spinning chamber 32 through the fiber passage 34 a. Of the fiber bundle F, the fibers that did not become yarn Y (that is, scraps of fibers before spinning) flow from the spinning chamber 32 through the gap 35 into the pressure reducing chamber 36 together with compressed air as fiber waste D. Through the inside of 37, it is recovered by the fiber waste recovery system 4. Details will be described later.
　図３に戻って、空気紡績装置１２の後方（糸走行方向下流側）には、糸監視装置４１が配置されている。糸監視装置４１は、空気紡績装置１２に不具合が起こって糸切れが発生した場合や、糸Ｙの太さ異常等がある場合に、糸欠陥を検出するためのものである。糸監視装置４１は、糸欠陥を検出した場合、ユニット制御部２０（図２参照）に糸欠陥検出信号を送信する。ユニット制御部２０は、糸欠陥検出信号を受信した場合、空気紡績装置１２への空気の供給を停止して、糸Ｙの生成を中断する。 Returning to FIG. 3, a yarn monitoring device 41 is disposed rearward (downstream in the yarn traveling direction) of the pneumatic spinning device 12. The yarn monitoring device 41 is for detecting a yarn defect when a defect occurs in the pneumatic spinning device 12 and a yarn breakage occurs, or when there is a thickness abnormality of the yarn Y or the like. When the yarn monitoring device 41 detects a yarn defect, the yarn monitoring device 41 transmits a yarn defect detection signal to the unit control unit 20 (see FIG. 2). When receiving the yarn defect detection signal, the unit control unit 20 stops the supply of air to the air spinning device 12 and interrupts the generation of the yarn Y.
　糸貯留装置１３は、糸監視装置４１の後方（糸走行方向下流側）に配置されている。糸貯留装置１３は、糸貯留ローラ４２と、糸掛け部材４３と、モータ４４とを有する。糸貯留ローラ４２は、その外周面に一定量の糸Ｙを巻き付けて一時的に貯留できるように構成されており、モータ４４によって回転駆動される。このとき、糸掛け部材４３が糸Ｙを引っ掛けた状態で糸貯留ローラ４２と一体回転することにより、糸貯留ローラ４２に糸Ｙが貯留される。糸貯留装置１３は、糸Ｙに張力を付与することによって、空気紡績装置１２から糸Ｙを引き出す。 The yarn storage device 13 is disposed rearward of the yarn monitoring device 41 (downstream in the yarn traveling direction). The yarn storage device 13 has a yarn storage roller 42, a yarn hooking member 43, and a motor 44. The yarn storage roller 42 is configured to be able to temporarily store a predetermined amount of yarn Y wound around the outer peripheral surface thereof, and is rotationally driven by a motor 44. At this time, the yarn hooking member 43 is integrally rotated with the yarn storage roller 42 in a state where the yarn Y is hooked, and the yarn Y is stored in the yarn storage roller 42. The yarn storage device 13 draws the yarn Y from the pneumatic spinning device 12 by applying tension to the yarn Y.
　巻取装置１５は、糸Ｙを綾振りしながらボビンＢに巻き取ることでパッケージＰを形成するためのものである。巻取装置１５は、糸貯留装置１３の上方且つ前方（糸走行方向下流側）に配置されている。巻取装置１５は、クレードル４７と、巻取ドラム４８等を有する。 The winding device 15 is for forming the package P by winding around the bobbin B while traversing the yarn Y. The winding device 15 is disposed above and in front of the yarn storage device 13 (downstream in the yarn traveling direction). The winding device 15 has a cradle 47, a winding drum 48, and the like.
　クレードル４７は、ボビンＢ（パッケージＰ）を回転可能に支持する。巻取ドラム４８は、クレードル４７に装着されたボビンＢに糸Ｙを巻き取ってパッケージＰを形成する巻取時に、ボビンＢ又はパッケージＰの外周面に接触する。巻取ドラム４８は、ドラム駆動モータ（不図示）によって回転駆動される。巻取ドラム４８の表面には、綾振り溝（不図示）が形成されており、糸Ｙは、綾振り溝に案内されることで、巻取ドラム４８の回転軸方向に綾振りされる。巻取ドラム４８が回転すると、クレードル４７に装着されたボビンＢ（パッケージＰ）が回転し、糸Ｙが綾振りされつつボビンＢに巻き取られる。 The cradle 47 rotatably supports the bobbin B (package P). The winding drum 48 contacts the outer peripheral surface of the bobbin B or the package P when winding the yarn Y around the bobbin B mounted on the cradle 47 to form the package P. The winding drum 48 is rotationally driven by a drum drive motor (not shown). A traverse groove (not shown) is formed on the surface of the take-up drum 48, and the yarn Y is traversed in the rotational axis direction of the take-up drum 48 by being guided to the traverse groove. When the winding drum 48 rotates, the bobbin B (package P) mounted on the cradle 47 rotates, and the yarn Y is wound around the bobbin B while being traversed.
　糸継装置１４は、糸貯留装置１３と巻取装置１５との間に設けられている。糸継装置１４は、何らかの原因によって糸Ｙが切断されたときに、上流側の糸Ｙと下流側の糸Ｙとを糸継ぎするためのものである。糸継装置１４は、例えば、旋回空気流によって糸継ぎを行うスプライサ装置や、機械式のノッタなどである。 The yarn joining device 14 is provided between the yarn storage device 13 and the winding device 15. The yarn joining device 14 is for joining the upstream yarn Y and the downstream yarn Y when the yarn Y is cut for some reason. The yarn joining device 14 is, for example, a splicer device that performs yarn joining by a swirling air flow, a mechanical knotter, or the like.
　紡績ユニット２には、糸継装置１４によって糸継ぎを行う際に糸継装置１４に糸Ｙを案内する糸捕捉案内装置５１、５２が設けられている。糸捕捉案内装置５１、５２は、先端部５１ａ、５２ａからそれぞれ糸Ｙを吸引可能に構成されている。糸捕捉案内装置５１は、糸継装置１４よりも下方に位置する基端部５１ｂを中心に、糸捕捉案内装置５２は、糸継装置１４よりも上方に位置する基端部５２ｂを中心に、それぞれ揺動可能に構成されている。糸捕捉案内装置５１を揺動させて、先端部５１ａを糸監視装置４１の下流側の位置まで移動させることで（図３の一点鎖線参照）、上流側の糸Ｙが先端部５１ａで捕捉される。そして、上流側の糸Ｙを捕捉した先端部５１ａを糸継装置１４の上方に移動させることで、上流側の糸Ｙが糸継装置１４に案内される。同様に、糸捕捉案内装置５２を揺動させて、先端部５２ａを巻取装置１５の上流側の位置まで揺動させることで（図３の一点鎖線参照）、下流側の糸Ｙが先端部５２ａで捕捉される。そして、下流側の糸Ｙを捕捉した先端部５２ａを糸継装置１４よりも下方の位置まで移動させることで、下流側の糸Ｙが糸継装置１４に案内される。 The spinning unit 2 is provided with yarn catching and guiding devices 51 and 52 for guiding the yarn Y to the yarn joining device 14 when the yarn joining device 14 performs yarn joining. The yarn catching and guiding devices 51, 52 are configured to be able to suck the yarn Y from the tip portions 51a, 52a, respectively. The yarn catching and guiding device 51 centers around the proximal end 51 b located below the yarn joining device 14, and the yarn catching and guiding device 52 centers around the proximal end 52 b positioned above the yarn joining device 14. Each is configured to be swingable. By swinging the yarn catching and guiding device 51 and moving the tip 51a to the downstream position of the yarn monitoring device 41 (see the alternate long and short dash line in FIG. 3), the yarn Y on the upstream side is caught by the tip 51a. Ru. Then, the upstream yarn Y is guided to the yarn joining device 14 by moving the tip end portion 51 a that has captured the upstream yarn Y above the yarn joining device 14. Similarly, the yarn catching and guiding device 52 is swung to swing the leading end 52a to the upstream position of the winding device 15 (see the alternate long and short dash line in FIG. 3). Captured at 52a. The downstream yarn Y is guided to the yarn joining device 14 by moving the tip portion 52a capturing the downstream yarn Y to a position below the yarn joining device 14.
　巻取装置１５と糸継装置１４の間には、糸監視装置１６が設けられている。糸監視装置１６は、糸Ｙの太さに異常がある等、糸Ｙに糸欠陥があることが検出されたときに、ユニット制御部２０に糸欠陥検出信号を送信する。ユニット制御部２０は、糸欠陥検出信号を受信したときに、糸監視装置１６が備えるカッター５５に糸Ｙを切断させる。 A yarn monitoring device 16 is provided between the winding device 15 and the yarn joining device 14. The yarn monitoring device 16 transmits a yarn defect detection signal to the unit control unit 20 when it is detected that there is a yarn defect in the yarn Y, such as an abnormality in the thickness of the yarn Y. When receiving the yarn defect detection signal, the unit controller 20 causes the cutter 55 provided in the yarn monitoring device 16 to cut the yarn Y.
　ユニット制御部２０は、紡績ユニット２の各部を制御するとともに、機台制御装置５と通信を行う。 The unit control unit 20 controls each unit of the spinning unit 2 and communicates with the machine control device 5.
　以上の構成を有する紡績ユニット２は、スライバケース２６から供給されるスライバＳをドラフト装置１１によってドラフトして、繊維束Ｆを生成する。さらに、紡績ユニット２は、繊維束Ｆを空気紡績装置１２で紡績して糸Ｙを生成し、糸Ｙを巻取装置１５でボビンＢに巻き取ることでパッケージＰを形成する。これらの一連の動作が、本発明の糸処理に相当する。 The spinning unit 2 having the above configuration drafts the sliver S supplied from the sliver case 26 by the draft device 11 to generate the fiber bundle F. Furthermore, the spinning unit 2 spins the fiber bundle F with the pneumatic spinning device 12 to produce the yarn Y, and winds the yarn Y around the bobbin B with the winding device 15 to form the package P. These series of operations correspond to the yarn processing of the present invention.
　上記糸処理が行われているとき、空気紡績装置１２に常に圧縮空気が供給され、空気紡績装置１２から空気及び繊維屑Ｄが常に排出される。このため、排出された繊維屑Ｄを回収する繊維屑回収システム４が、回収された繊維屑Ｄを外部へ排出する際に繊維屑Ｄの回収を中断しなければならないような構成になっていると、上記糸処理自体を中断しなければならず、生産効率が低下するおそれがある。そこで、本実施形態の繊維屑回収システム４は、紡績ユニット２の動作を止めなくても、空気紡績装置１２から排出される繊維屑Ｄを常時回収しつつ、回収された繊維屑Ｄを任意のタイミングで外部へ排出可能にするための構成を備える。以下、繊維屑回収システム４の詳細について、図５～図８を用いて説明する。 When the yarn processing is being performed, compressed air is always supplied to the pneumatic spinning device 12, and air and fiber waste D are always discharged from the pneumatic spinning device 12. Therefore, the fiber waste collection system 4 for collecting the discharged fiber waste D is configured such that the collection of the fiber waste D must be interrupted when discharging the collected fiber waste D to the outside. And, the above-mentioned yarn processing itself has to be interrupted, and there is a possibility that the production efficiency may be lowered. Therefore, the fiber waste collection system 4 of this embodiment can collect any fiber waste D while always collecting the fiber waste D discharged from the pneumatic spinning device 12 without stopping the operation of the spinning unit 2. It has a configuration for enabling discharge to the outside at timing. Hereinafter, details of the fiber waste collection system 4 will be described with reference to FIGS. 5 to 8.

The other ends of the plurality of ducts 37 are connected to the section duct 63, respectively. The section duct 63 is connected to the fiber waste separation part 64, and is in communication with the internal space 74 of the fiber waste separation part 64 via an inlet 75 described later.
　繊維屑分離部６４は、複数の紡績ユニット２の空気紡績装置１２から排出された繊維屑Ｄを空気と分離するためのものである。繊維屑分離部６４は、複数の紡績ユニット２に共通に設けられている。繊維屑分離部６４は、略円柱形状を有する部材である（図６及び図７参照）。図６に示すように、繊維屑分離部６４は、内周面７３を有する周壁７１と、周壁７１の上端部に設けられた上壁７２とを有する。内周面７３は、その全体がテーパ面になっている。すなわち、周壁７１の内径は、上方に向かうにつれて小さくなり、下方に向かうにつれて大きくなっている。周壁７１及び上壁７２により、繊維屑分離部６４には、略円錐台形状の内部空間７４が形成されている。 The fiber waste separation unit 64 is for separating the fiber waste D discharged from the pneumatic spinning device 12 of the plurality of spinning units 2 from the air. The fiber waste separation unit 64 is provided commonly to the plurality of spinning units 2.

The entire inner circumferential surface 73 is a tapered surface. That is, the inner diameter of the peripheral wall 71 decreases as it goes upward, and increases as it goes downward. A substantially frusto-conical internal space 74 is formed in the fiber waste separation portion 64 by the peripheral wall 71 and the upper wall 72.
　周壁７１の上下方向における途中部には、流入口７５が形成されている。また、上下方向に直交する断面において、流入口７５から内周面７３の接線方向に延び、周壁７１の外周面から突出した管７８が設けられている（図７参照）。管７８には、セクションダクト６３が連結されている。これにより、繊維屑Ｄを含んだ空気は、セクションダクト６３及び管７８を通り、流入口７５を介して内部空間７４に流入する。上壁７２には、空気を排出するための排気口７６が形成されている。すなわち、排気口７６は、流入口７５よりも上方に配置されている。また、繊維屑分離部６４の下側の端面のほぼ全域に亘って、略円形状の繊維屑排出口７７が形成されている。すなわち、繊維屑排出口７７は、流入口７５よりも下方に配置されている。 An inflow port 75 is formed in the middle of the peripheral wall 71 in the vertical direction. Further, in a cross section perpendicular to the vertical direction, a pipe 78 extending from the inflow port 75 in the tangential direction of the inner peripheral surface 73 and protruding from the outer peripheral surface of the peripheral wall 71 is provided (see FIG. 7). A section duct 63 is connected to the pipe 78. As a result, air containing fiber waste D flows through the section duct 63 and the pipe 78 into the internal space 74 through the inlet 75. The upper wall 72 is formed with an exhaust port 76 for discharging air. That is, the exhaust port 76 is disposed above the inflow port 75. Further, a substantially circular fiber waste discharge port 77 is formed over substantially the entire area of the lower end face of the fiber waste separation part 64. That is, the fiber waste discharge port 77 is disposed below the inflow port 75.
　ブロア部６５は、繊維屑分離部６４の内部空間７４に旋回流を発生させるためのものである。ブロア部６５は、例えば回転することで空気を外部へ排出するファン（不図示）を有する。ブロア部６５は、繊維屑分離部６４の上方に配置され、排気口７６を介して繊維屑分離部６４と接続されている。ブロア部６５は、回収システム制御部６２と電気的に接続されており（図２参照）、回収システム制御部６２によってその動作が制御される。 The blower portion 65 is for generating a swirling flow in the internal space 74 of the fiber waste separation portion 64. The blower unit 65 has a fan (not shown) that discharges air to the outside by rotating, for example. The blower portion 65 is disposed above the fiber waste separation part 64 and connected to the fiber waste separation part 64 via the exhaust port 76. The blower unit 65 is electrically connected to the collection system control unit 62 (see FIG. 2), and its operation is controlled by the collection system control unit 62.
　繊維屑回収部６６は、繊維屑排出口７７から排出された繊維屑Ｄを回収するためのものである。図６に示すように、繊維屑回収部６６は、繊維屑分離部６４の下方に配置されている。繊維屑回収部６６は、箱状部材８１と、扉部８２とを有する。箱状部材８１は、中空の略直方体形状を有する。これにより、箱状部材８１の内部には、略直方体状の内部空間８３が形成されている。箱状部材８１の上端部には略円状の開口が形成され、箱状部材８１の上端部と繊維屑分離部６４の下側部分とが接合されている。繊維屑分離部６４の内部空間７４と繊維屑回収部６６の内部空間８３は、繊維屑排出口７７を介して連通可能になっている。また、箱状部材８１の下面のほぼ全域に亘って、内部空間８３と外部を連通させる開口８４が形成されている。扉部８２は、例えば、２つの回収扉８５、８６を有する。２つの回収扉８５、８６は、板状の部材であり、後述する支持部材９２を囲い、且つ、開口８４を塞ぐ形状を有する。回収扉８５、８６は、例えば、レバー操作によって、手動で開閉可能に構成されている。回収扉８５は、開口８４を塞ぐ閉止位置（図６（ａ）参照）と、閉止位置よりも左方であり、開口８４を開放する開放位置（図６（ｂ）参照）との間で移動可能に構成されている。同様に、回収扉８６は、閉止位置と、閉止位置よりも右方である開放位置との間で移動可能に構成されている。回収扉８５、８６が閉止位置にあるとき、繊維屑回収部６６の内部空間８３は、外部に対して密閉された密閉状態にある。回収扉８５、８６が開放位置にあるとき、繊維屑回収部６６の内部空間８３は、外部に対して開放された開放状態にある。このように、繊維屑回収部６６は、密閉状態と開放状態との間で状態変更が可能になっている。 The fiber waste recovery unit 66 is for recovering the fiber waste D discharged from the fiber waste discharge port 77. As shown in FIG. 6, the fiber waste recovery unit 66 is disposed below the fiber waste separation unit 64. The fiber waste collection unit 66 has a box-like member 81 and a door 82. The box-like member 81 has a hollow substantially rectangular parallelepiped shape. Thus, a substantially rectangular parallelepiped internal space 83 is formed inside the box-like member 81. A substantially circular opening is formed at the upper end of the box-like member 81, and the upper end of the box-like member 81 and the lower portion of the fiber waste separation part 64 are joined. The internal space 74 of the fiber separation part 64 and the internal space 83 of the fiber collection part 66 can be communicated via the fiber discharge port 77. Further, an opening 84 for communicating the internal space 83 with the outside is formed over substantially the entire area of the lower surface of the box-like member 81. The door 82 has, for example, two recovery doors 85 and 86. The two recovery doors 85 and 86 are plate-like members, and have a shape that encloses a support member 92 described later and closes the opening 84. The recovery doors 85 and 86 are configured to be able to be opened and closed manually by, for example, a lever operation. The recovery door 85 moves between a closed position (see FIG. 6A) closing the opening 84 and an open position (see FIG. 6B) left of the closed position and opening the opening 84. It is configured to be possible. Similarly, the recovery door 86 is configured to be movable between a closed position and an open position that is to the right of the closed position. When the recovery doors 85 and 86 are in the closed position, the internal space 83 of the fiber debris recovery unit 66 is in a closed state sealed from the outside. When the recovery doors 85 and 86 are in the open position, the internal space 83 of the fiber waste recovery unit 66 is in an open state open to the outside. Thus, the fiber waste recovery unit 66 can be changed in state between the closed state and the open state.
　シャッタ機構６７は、繊維屑排出口７７を開閉することで、繊維屑分離部６４の内部空間７４と繊維屑回収部６６の内部空間８３を連通させ、又は遮断するためのものである。シャッタ機構６７は、例えば、シャッタ９１と、支持部材９２と、エアシリンダ９３（本発明の駆動部）等を有する。シャッタ９１は、その上面が繊維屑排出口７７と略等しい大きさの略円形状を有する円板状部材である。支持部材９２は、シャッタ９１と連結され、シャッタ９１を下方から支持する略筒状の部材である。エアシリンダ９３は、圧縮空気が供給・排出される作動室（不図示）を有し、作動室への圧縮空気の供給・排出によって支持部材９２及びシャッタ９１を上下移動させるように構成されている。作動室への圧縮空気の供給・排出は、具体的には、例えば電磁弁９４（図２参照）の開閉により行われる。電磁弁９４は、回収システム制御部６２と電気的に接続されており、回収システム制御部６２によってその動作が制御される。 The shutter mechanism 67 is for opening or closing the fiber waste discharge port 77 to connect or block the internal space 74 of the fiber separation part 64 and the internal space 83 of the fiber collection part 66. The shutter mechanism 67 includes, for example, a shutter 91, a support member 92, an air cylinder 93 (drive unit of the present invention), and the like. The shutter 91 is a disk-like member having a substantially circular shape whose upper surface is substantially equal in size to the fiber waste discharge port 77. The support member 92 is a substantially cylindrical member that is connected to the shutter 91 and supports the shutter 91 from below. The air cylinder 93 has a working chamber (not shown) into which compressed air is supplied and discharged, and is configured to move the support member 92 and the shutter 91 up and down by the supply and discharge of the compressed air to the working chamber . Specifically, the supply and discharge of compressed air to the working chamber is performed, for example, by opening and closing of the solenoid valve 94 (see FIG. 2). The solenoid valve 94 is electrically connected to the recovery system control unit 62, and the operation is controlled by the recovery system control unit 62.
　シャッタ９１は、エアシリンダ９３の動作によって、連通位置と、連通位置よりも上方である遮断位置との間で移動可能になっている。すなわち、シャッタ９１が連通位置に位置しているとき、シャッタ９１は、繊維屑排出口７７を開放しており、繊維屑分離部６４の内部空間７４と繊維屑回収部６６の内部空間８３が連通している（図６（ａ）参照）。一方、シャッタ９１が遮断位置に位置しているとき、シャッタ９１は、繊維屑排出口７７を塞いでおり、繊維屑分離部６４の内部空間７４と繊維屑回収部６６の内部空間８３が遮断されている（図６（ｂ）参照）。このように、シャッタ９１は、繊維屑排出口７７を開閉可能、且つ、連通位置と遮断位置との間で上下移動可能になっている。 The shutter 91 is movable between the communication position and the blocking position above the communication position by the operation of the air cylinder 93. That is, when the shutter 91 is located at the communication position, the shutter 91 opens the fiber waste outlet 77, and the internal space 74 of the fiber separating part 64 and the internal space 83 of the fiber collecting part 66 are in communication (See FIG. 6 (a)). On the other hand, when the shutter 91 is at the blocking position, the shutter 91 closes the fiber waste outlet 77, and the internal space 74 of the fiber separating part 64 and the internal space 83 of the fiber collecting part 66 are isolated. (See FIG. 6 (b)). Thus, the shutter 91 can open and close the fiber waste discharge port 77 and can move up and down between the communication position and the blocking position.
　回収システム制御部６２は、ＣＰＵと、ＲＯＭと、ＲＡＭ等を備える。回収システム制御部６２は、ＲＯＭに格納されたプログラムに従い、ＣＰＵにより各部を制御する。回収システム制御部６２は、上述したブロア部６５及び電磁弁９４等を制御可能に構成されており、本発明の気流制御部及びシャッタ制御部として機能する。また、回収システム制御部６２は、機台制御装置５と通信を行う。 The collection system control unit 62 includes a CPU, a ROM, a RAM, and the like. The collection system control unit 62 controls each unit by the CPU in accordance with the program stored in the ROM. The collection system control unit 62 is configured to be able to control the blower unit 65, the solenoid valve 94, and the like described above, and functions as an air flow control unit and a shutter control unit according to the present invention. Further, the collection system control unit 62 communicates with the machine control device 5.
（繊維屑回収システムの動作）
　次に、以上の構成を備える繊維屑回収システム４の動作について、図５、図７、図８を用いて説明する。図８は、繊維屑分離部６４内の繊維屑Ｄの動きを示す図である。なお、図５、図７、図８の破線矢印は、空気の流れを、実線矢印は、繊維屑Ｄの流れをそれぞれ示している。 (Operation of waste fiber recovery system)
Next, the operation of the fiber waste collection system 4 having the above configuration will be described with reference to FIGS. 5, 7, and 8. FIG. FIG. 8 is a view showing the movement of the fiber waste D in the fiber waste separation part 64. As shown in FIG. The broken arrows in FIGS. 5, 7 and 8 indicate the flow of air, and the solid arrows indicate the flow of fiber waste D.
（繊維屑と空気の分離）
　繊維屑回収システム４を用いた繊維屑Ｄと空気の分離について説明する。まず、複数の紡績ユニット２が、それぞれ上述した糸処理を行っている。すなわち、複数の紡績ユニット２が、空気紡績装置１２によって糸Ｙを生成しつつ、生成した糸ＹをボビンＢに巻き取っている。この動作中、空気紡績装置１２からは、繊維屑を含んだ空気がダクト３７へ常時排出される。 (Separation of fiber waste and air)
The separation of the fiber waste D and the air using the fiber waste collection system 4 will be described. First, the plurality of spinning units 2 perform the above-described yarn processing. That is, the plurality of spinning units 2 wind the produced yarn Y around the bobbin B while producing the yarn Y by the pneumatic spinning device 12. During this operation, air containing fiber waste is constantly discharged from the air spinning device 12 to the duct 37.
　機台制御装置５は、各紡績ユニット２のユニット制御部２０及び繊維屑回収システム４の回収システム制御部６２と定期的に通信を行っている。機台制御装置５は、ある紡績ユニット２が糸処理を行っているとき、回収システム制御部６２に、当該紡績ユニット２と接続された繊維屑回収ユニット６１のブロア部６５を制御させて、ブロア部６５を常に動作させる。 The machine control device 5 periodically communicates with the unit control unit 20 of each spinning unit 2 and the collection system control unit 62 of the fiber waste collection system 4. When a certain spinning unit 2 is performing yarn processing, the machine control device 5 causes the recovery system control unit 62 to control the blower unit 65 of the fiber waste recovery unit 61 connected to the spinning unit 2 to perform blower processing. The unit 65 is always operated.
　ある繊維屑回収ユニット６１のブロア部６５が動作すると、排気口７６を介して繊維屑分離部６４内の空気が排出される。すると、繊維屑分離部６４の内部空間７４に負圧が発生し、繊維屑Ｄを含んだ空気が、ダクト３７及びセクションダクト６３内を通り、流入口７５を介して繊維屑分離部６４内へ流入する。図７及び図８に示すように、繊維屑分離部６４内に流入した空気は、内周面７３に沿って流れ、上下方向を軸方向として、軸方向周りに旋回する旋回流となり、排気口７６を介して排出される。このように、ブロア部６５の動作によって旋回流が生成される。 When the blower unit 65 of a certain fiber waste collection unit 61 operates, air in the fiber separation part 64 is discharged through the exhaust port 76. Then, a negative pressure is generated in the internal space 74 of the fiber waste separation part 64, and air containing fiber waste D passes through the inside of the duct 37 and the section duct 63 and into the fiber waste separation part 64 through the inflow port 75. To flow. As shown in FIG. 7 and FIG. 8, the air that has flowed into the fiber waste separation part 64 flows along the inner circumferential surface 73 and becomes a swirling flow that turns around the axial direction with the vertical direction as the axial direction. Exhausted through 76. Thus, the swirling flow is generated by the operation of the blower unit 65.
　空気とともに内部空間７４へ流入した繊維屑Ｄは、内周面７３に沿って渦を巻くように移動する。これにより、繊維屑Ｄには、渦の径方向外側へ向かう遠心力１００が作用する（図８参照）。ここで、上述したように、周壁７１の内径は、流入口７５から下方（繊維屑排出口７７側）へ向かうにつれて大きくなっている。このため、遠心力１００は、内周面７３と垂直な成分１０１（繊維屑Ｄの移動に寄与しない成分）と、内周面７３と平行な成分１０２（繊維屑Ｄを上下方向における繊維屑排出口７７側へ向かわせる成分）に分解できる。後者の成分１０２により、繊維屑Ｄは、内周面７３に沿って、上下方向における繊維屑排出口７７側へ案内される。また、繊維屑Ｄには重力も作用するため、流入口７５よりも下方に位置する繊維屑排出口７７側へさらに移動しやすい。このようにして、繊維屑分離部６４内の繊維屑Ｄは、排気口７６から排出される空気と分離される。空気と分離された繊維屑Ｄは、図８（ａ）に示すように、シャッタ９１が連通位置にある場合、繊維屑排出口７７を介して繊維屑回収部６６の内部空間８３に回収され、内部空間８３の底部に堆積する。このとき、回収扉８５、８６を閉止位置に位置させておくことで、繊維屑回収部６６の内部空間８３が密閉状態になり、外部の空気が繊維屑回収部６６内に流れ込むことが防止される。 The fiber waste D that has flowed into the inner space 74 with the air moves along the inner circumferential surface 73 so as to swirl. Thereby, the centrifugal force 100 which goes to the radial direction outer side of a vortex acts on the fiber waste D (refer FIG. 8). Here, as described above, the inner diameter of the peripheral wall 71 increases from the inflow port 75 toward the lower side (the side of the fiber waste discharge port 77). For this reason, the centrifugal force 100 includes the component 101 (component not contributing to the movement of the fiber waste D) perpendicular to the inner peripheral surface 73 and the component 102 parallel to the inner peripheral surface 73 (fiber waste D in the vertical direction Can be decomposed into the components to be directed to the outlet 77 side. By the latter component 102, the fiber waste D is guided along the inner circumferential surface 73 to the fiber waste outlet 77 side in the vertical direction. In addition, since gravity also acts on the fiber waste D, the fiber waste D is more easily moved to the fiber waste outlet 77 side located below the inflow port 75. Thus, the fiber waste D in the fiber waste separation part 64 is separated from the air exhausted from the exhaust port 76. As shown in FIG. 8A, when the shutter 91 is in the communication position, the fiber waste D separated from the air is collected into the internal space 83 of the fiber waste collection unit 66 through the fiber discharge port 77, It deposits on the bottom of the internal space 83. At this time, by positioning the recovery doors 85 and 86 in the closed position, the internal space 83 of the fiber debris recovery unit 66 is sealed, and external air is prevented from flowing into the fiber debris recovery unit 66. Ru.
（繊維屑の外部への排出）
　次に、堆積した繊維屑Ｄの外部への排出について説明する。繊維屑Ｄを繊維屑回収部６６の内部空間８３から外部へ排出する場合、回収扉８５、８６を開放することで繊維屑回収部６６を開放状態にする必要がある。但し、シャッタ９１が連通位置にあるときに繊維屑回収部６６を開放状態にすると、繊維屑回収部６６の内部空間８３及び繊維屑回収部６６の内部空間８３の気圧が大気圧よりも低いため、外部の空気が流れ込み、繊維屑Ｄが繊維屑分離部６４内に逆流するおそれがある。そこで、繊維屑Ｄの排出にあたっては、図８（ｂ）に示すように、シャッタ９１を遮断位置に移動させて、繊維屑分離部６４の内部空間と繊維屑回収部６６の内部空間８３を遮断する。具体的には、例えば、オペレータが原動機ボックス３の操作部７を操作して、機台制御装置５を介して回収システム制御部６２がエアシリンダ９３を動作させることで、シャッタ９１を遮断位置に移動させる。これにより、ブロア部６５の動作中に回収扉８５、８６を開放位置に移動させても、繊維屑分離部６４の内部空間７４に外部の空気が流れ込むことが防止される。このようにして、オペレータの手作業又はロボット等により繊維屑Ｄを繊維屑回収部６６の内部空間８３から排出することが可能になる。この排出作業中でも、ブロア部６５を常時動作させ、繊維屑Ｄと空気との分離を常時行うことが可能である。 (Discharge of fiber waste to the outside)
Next, discharge of the accumulated fiber waste D to the outside will be described. In the case of discharging the fiber waste D from the internal space 83 of the fiber waste collection part 66 to the outside, it is necessary to open the fiber waste collection part 66 by opening the collection doors 85 and 86. However, if the fiber debris recovery unit 66 is opened when the shutter 91 is in the communication position, the air pressure in the internal space 83 of the fiber debris recovery unit 66 and the internal space 83 in the fiber debris recovery unit 66 is lower than atmospheric pressure. There is a possibility that the outside air flows in and the fiber waste D flows back into the fiber separation part 64. Therefore, when discharging the fiber waste D, as shown in FIG. 8B, the shutter 91 is moved to the blocking position to shut off the internal space of the fiber separating part 64 and the internal space 83 of the fiber collecting part 66. Do. Specifically, for example, when the operator operates the operation unit 7 of the prime mover box 3 and the recovery system control unit 62 operates the air cylinder 93 via the machine control device 5, the shutter 91 is brought to the blocking position. Move it. As a result, even if the recovery doors 85 and 86 are moved to the open position during the operation of the blower portion 65, external air is prevented from flowing into the internal space 74 of the fiber waste separation portion 64. In this manner, it is possible to discharge the fiber waste D from the internal space 83 of the fiber waste collection unit 66 by the manual operation of the operator or the robot or the like. Even during this discharging operation, it is possible to always operate the blower section 65 to always separate the fiber waste D and the air.
　以上のように、周壁７１の内径は、上下方向において、流入口７５から繊維屑排出口７７に向かうにつれて大きくなっている。これにより、流入口７５から流入した繊維屑Ｄに作用する遠心力１００は、周壁７１の内周面７３に垂直な成分と平行な成分に分解され、繊維屑Ｄは、内周面７３に沿って、内径が大きくなる側、すなわち繊維屑排出口７７側に案内される。したがって、流入口７５から流入した繊維屑Ｄが排気口７６側に吸い寄せられることを防ぎ、且つ、繊維屑Ｄを繊維屑排出口７７側に確実に移動させることができる。 As described above, the inner diameter of the peripheral wall 71 increases in the vertical direction from the inflow port 75 toward the fiber waste discharge port 77. Thereby, the centrifugal force 100 acting on the fiber waste D flowing in from the inflow port 75 is decomposed into a component parallel to a component perpendicular to the inner peripheral surface 73 of the peripheral wall 71, and the fiber waste D is along the inner peripheral surface 73. Then, it is guided to the side where the inner diameter is increased, that is, the side of the fiber waste outlet 77. Therefore, the fiber waste D flowing from the inflow port 75 can be prevented from being attracted to the exhaust port 76 side, and the fiber waste D can be reliably moved to the fiber waste outlet 77 side.
　また、繊維屑回収部６６が、密閉状態と開放状態との間で状態変更可能である。さらに、繊維屑回収部６６の内部空間８３と繊維屑分離部６４の内部空間７４が連通可能に構成されており、シャッタ９１が、内部空間７４と内部空間８３を連通させる連通位置と、これらを遮断する遮断位置との間で移動可能である。繊維屑回収部６６が密閉状態にあり、且つ、シャッタ９１が連通位置にあるときには、繊維屑回収部６６に繊維屑が回収される。一方、シャッタ９１が遮断位置にあるときには、ブロア部６５の動作中に繊維屑回収部６６を開放状態にしても、外部から繊維屑分離部６４に空気が流入して繊維屑Ｄが逆流することを防止できるので、繊維屑回収部６６を開放状態にして、回収された繊維屑Ｄを外部へ排出できる。したがって、ブロア部６５が動作中の場合でも、繊維屑Ｄの外部への排出を可能にすることができる。 Moreover, the fiber waste collection part 66 can be changed in state between the closed state and the open state. Furthermore, the internal space 83 of the fiber waste collection part 66 and the internal space 74 of the fiber separation part 64 can communicate with each other, and the shutter 91 communicates the internal space 74 with the internal space 83, and It is movable between a blocking position to be blocked. When the fiber waste collection part 66 is in a closed state and the shutter 91 is in the communication position, the fiber waste collection part 66 collects fiber waste. On the other hand, when the shutter 91 is in the blocking position, air flows from the outside into the fiber waste separation part 64 and the fiber waste D flows back even if the fiber waste collection part 66 is opened during the operation of the blower part 65 Can be prevented, and the collected fiber waste D can be discharged to the outside by setting the fiber waste collection part 66 in an open state. Therefore, even when the blower section 65 is in operation, the waste fiber D can be discharged to the outside.
　また、鉛直方向において流入口７５から繊維屑排出口７７へ向かう側に重力が作用するので、繊維屑Ｄをより確実に繊維屑排出口７７側に移動させることができる。 Further, since gravity acts on the side from the inflow port 75 toward the fiber waste outlet 77 in the vertical direction, the fiber waste D can be more reliably moved to the fiber waste outlet 77 side.
　また、周壁７１の内周面７３全体がテーパ面になっているため、軸方向における周壁７１の内周面全体に渡って、繊維屑は、内周面７３に沿って、内径が大きくなる側、すなわち繊維屑排出口側に案内される。従って、流入口７５から流入した繊維屑が排気口側に吸い寄せられることを確実に防ぎ、且つ、繊維屑を繊維屑排出口側により確実且つスムーズに移動させることができる。 In addition, since the entire inner peripheral surface 73 of the peripheral wall 71 is a tapered surface, the fiber waste has a larger inner diameter along the inner peripheral surface 73 over the entire inner peripheral surface of the peripheral wall 71 in the axial direction. That is, it is guided to the fiber waste outlet side. Therefore, it is possible to reliably prevent the fiber waste that has flowed in from the inflow port 75 from being attracted to the exhaust port side, and to move the fiber waste more reliably and smoothly on the fiber waste outlet side.
　また、繊維屑排出口７７が、繊維屑分離部６４の下方側の端面の全域に亘って形成されているため、繊維屑Ｄを繊維屑排出口７７に引っかかりにくくすることができる。また、繊維屑排出口７７の面積を大きくすることができる。したがって、繊維屑Ｄを繊維屑排出口７７から確実に排出することができる。 Further, since the fiber waste discharge port 77 is formed over the entire end face on the lower side of the fiber waste separation portion 64, the fiber waste D can be made less likely to be caught by the fiber waste discharge port 77. In addition, the area of the fiber waste discharge port 77 can be increased. Therefore, the fiber waste D can be reliably discharged from the fiber waste discharge port 77.
　また、シャッタ９１が繊維屑排出口７７を開閉可能、且つ、上下方向に移動可能であるため、繊維屑排出口７７を完全に開放又は閉止するために必要なシャッタ９１の移動距離を短くすることができる。したがって、繊維屑排出口７７の開閉にかかる時間を短くすることができる。 In addition, since the shutter 91 can open and close the fiber waste outlet 77 and can move in the vertical direction, the moving distance of the shutter 91 necessary to completely open or close the fiber outlet 77 can be shortened. Can. Therefore, the time taken to open and close the fiber waste discharge port 77 can be shortened.
　また、紡績ユニット２が糸処理を行っているときに、常にブロア部６５が動作していても、繊維屑排出口７７を塞ぐシャッタ９１が設けられているため、繊維屑回収部６６に溜まった繊維屑Ｄを任意のタイミングで外部へ排出できる。したがって、繊維屑Ｄを外部へ排出する際に糸処理を停止させる必要がなく、生産効率の低下を防止することができる。 In addition, when the spinning unit 2 is performing yarn processing, even if the blower unit 65 is always operating, the shutter 91 for closing the fiber waste discharge port 77 is provided, and therefore the fiber waste collection unit 66 is collected. The fiber waste D can be discharged to the outside at any timing. Therefore, there is no need to stop the yarn processing when discharging the fiber waste D to the outside, and a decrease in production efficiency can be prevented.
　また、複数の紡績ユニット２において発生する繊維屑Ｄが、複数の紡績ユニット２に共通に設けられた繊維屑分離部６４に流れ込む。したがって、紡績ユニット２毎に繊維屑分離部６４を設置する必要がなく、コストの増加を抑えることができる。 Further, the fiber waste D generated in the plurality of spinning units 2 flows into the fiber waste separation portion 64 provided commonly to the plurality of spinning units 2. Therefore, it is not necessary to install the fiber waste separation part 64 for every spinning unit 2, and the increase in cost can be suppressed.
　また、繊維屑回収部６６が各繊維屑分離部６４にそれぞれ対応して設けられているため、繊維屑回収部６６の大型化を抑制できる。 Moreover, since the fiber waste collection part 66 is provided corresponding to each fiber waste separation part 64, the enlargement of the fiber waste collection part 66 can be suppressed.
　また、ブロア部６５が各繊維屑分離部６４にそれぞれ対応して設けられているため、ブロア部６５の大型化や騒音発生等を抑制できる。 Moreover, since the blower part 65 is provided corresponding to each fiber waste separation part 64, the enlargement of the blower part 65, noise generation, etc. can be suppressed.
　次に、前記実施形態に変更を加えた変形例について説明する。但し、前記実施形態と同様の構成を有するものについては、同じ符号を付して適宜その説明を省略する。 Next, a modified example in which the embodiment is modified will be described. However, about what has the same structure as the said embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted suitably.
（１）前記実施形態においては、繊維屑分離部６４の内周面７３全体がテーパ面であるものとしたが、これには限られない。例えば、上下方向において流入口７５から繊維屑排出口７７側にかけて、湾曲面になっていても良い。また、流入口７５から排気口７６側へ向かうにつれて周壁７１の内径が小さくなっていなくても良い。例えば、当該内径が、上下方向において流入口７５から排気口７６にかけて一定でも良い。少なくとも、上下方向において流入口７５から繊維屑排出口７７側へ向かうにつれて、周壁７１の内径が大きくなっていれば良い。 (1) In the said embodiment, although the whole inner peripheral surface 73 of the fiber waste isolation | separation part 64 shall be a taper surface, it is not restricted to this. For example, it may be a curved surface from the inflow port 75 to the fiber waste discharge port 77 side in the vertical direction. Further, the inner diameter of the peripheral wall 71 does not have to be smaller from the inflow port 75 toward the exhaust port 76 side. For example, the inner diameter may be constant from the inlet 75 to the outlet 76 in the vertical direction. The inner diameter of the peripheral wall 71 may be increased at least as it goes from the inflow port 75 toward the fiber waste discharge port 77 in the vertical direction.
（２）前記までの実施形態において、排気口７６は上壁７２に形成されているものとしたが、これには限られない。排気口７６は、上下方向において流入口７５を挟んで繊維屑排出口７７の反対側に配置されていれば良く、例えば周壁７１に形成されていても良い。 (2) Although the exhaust port 76 is formed in the upper wall 72 in the above embodiments, the invention is not limited thereto. The exhaust port 76 may be disposed on the opposite side of the fiber waste outlet 77 across the inflow port 75 in the vertical direction, and may be formed, for example, on the peripheral wall 71.
（３）前記までの実施形態において、シャッタ９１が上下移動可能に構成されているものとしたが、これには限られない。シャッタ９１が、例えば、前後左右方向を含む斜め方向に移動可能でも良い。シャッタ９１が少なくとも上下方向に移動可能であることで、シャッタ９１の開閉の所要時間を短くすることができる。或いは、シャッタ９１の開閉に時間はかかるが、シャッタ９１が前後方向又は左右方向にのみ移動可能であっても良い。 (3) In the above embodiments, the shutter 91 is configured to be vertically movable, but the present invention is not limited to this. For example, the shutter 91 may be movable in an oblique direction including the front, rear, left, and right directions. Since the shutter 91 is movable at least in the vertical direction, the required time for opening and closing the shutter 91 can be shortened. Alternatively, although it takes time to open and close the shutter 91, the shutter 91 may be movable only in the front-rear direction or the left-right direction.
（４）前記までの実施形態において、繊維屑排出口７７が、繊維屑分離部６４の下側の端面のほぼ全域に亘って形成されているものとしたが、別の構成であっても良い。例えば、図９及び図１０に示す繊維屑回収ユニット６１ａにおいて、繊維屑分離部６４ａの周壁７１ａに繊維屑排出口７７ａが形成されていても良い。より詳細には、繊維屑分離部６４ａは、周壁７１ａの下端を塞ぐ底部７９を有し、繊維屑排出口７７ａは、周壁７１ａの下端部に形成されている。さらに、図１０に示すように、繊維屑分離部６４ａが、上下方向に直交する断面において、繊維屑排出口７７ａから、内周面７３ａの、繊維屑排出口７７ａの形成位置（点１０３）における接線方向に延びる管８０（本発明の管部）を有している。より詳細には、管８０は、繊維屑Ｄが旋回する方向の延長線上に配置されている。また、図９に示すように、繊維屑回収部６６ａが繊維屑分離部６４ａの側方に配置され、繊維屑分離部６４ａの内部空間７４ａと繊維屑回収部６６ａの内部空間８３ａを連通させる開口８７が、箱状部材８１ａの側面に形成されていても良い。また、開口８７が形成された側面と反対側の側面に、内部空間８３ａと外部を連通させる開口８４ａが形成され、開口８４ａを塞ぐ扉部８２ａが設けられていても良い。なお、扉部８２ａは、例えば、モータ８８等によって開閉可能に構成されていても良い。さらに、シャッタ機構６７ａが、開口８４ａを塞ぐシャッタ９１ａと、シャッタ９１ａの側面部を支持する支持部材９２ａを有し、シャッタ９１ａが左右方向に移動可能に構成されていても良い。 (4) In the embodiments described above, the fiber waste discharge port 77 is formed over substantially the entire end face on the lower side of the fiber waste separation part 64, but another configuration may be used. . For example, in the fiber waste collection unit 61a shown in FIG. 9 and FIG. 10, a fiber waste discharge port 77a may be formed in the peripheral wall 71a of the fiber separation part 64a. More specifically, the fiber waste separation part 64a has a bottom part 79 that closes the lower end of the peripheral wall 71a, and the fiber waste outlet 77a is formed at the lower end of the peripheral wall 71a. Furthermore, as shown in FIG. 10, in the cross section orthogonal to the up and down direction, the fiber waste separation part 64a from the fiber waste discharge port 77a to the formation position (point 103) of the fiber waste discharge port 77a It has a tangentially extending tube 80 (the tube of the present invention). More specifically, the pipe 80 is disposed on an extension of the direction in which the fiber waste D pivots. Further, as shown in FIG. 9, an opening where the fiber waste collection part 66a is disposed on the side of the fiber waste separation part 64a and the internal space 74a of the fiber separation part 64a and the internal space 83a of the fiber collection part 66a are communicated. 87 may be formed in the side of boxy member 81a. In addition, an opening 84a may be formed on the side opposite to the side on which the opening 87 is formed to communicate the internal space 83a with the outside, and a door 82a may be provided to close the opening 84a. The door 82 a may be configured to be openable and closable by, for example, a motor 88 or the like. Furthermore, the shutter mechanism 67a may have a shutter 91a for closing the opening 84a and a support member 92a for supporting the side surface portion of the shutter 91a, and the shutter 91a may be configured to be movable in the left-right direction.
　以上の構成により、前記までの実施形態と比較して繊維屑排出口７７ａを小さくすることができ、シャッタ９１ａのサイズを小さくすることができる。また、管８０が内周面７３ａの接線方向に延びているため、分離された繊維屑Ｄが、管８０に沿って滑らかに繊維屑回収部６６ａ側へ流れる。したがって、繊維屑Ｄをスムーズに排出することができる。また、繊維屑排出口７７ａが周壁７１ａの下端部に形成されているため、仮に繊維屑Ｄが繊維屑排出口７７ａから排出され損なった場合でも、繊維屑Ｄは、旋回して再び繊維屑排出口７７ａ付近に移動する。したがって、繊維屑Ｄが底部７９の近傍に溜まることを抑制できる。なお、この変形例に置いて、シャッタ９１ａは、開口８４ａを開閉可能に構成されているものとしたが、これには限られない。例えば、シャッタ９１ａは、管８０の途中部等に設けられても良い。 With the above configuration, the fiber waste discharge port 77a can be made smaller as compared with the embodiments described above, and the size of the shutter 91a can be made smaller. Further, since the pipe 80 extends in the tangential direction of the inner circumferential surface 73a, the separated fiber waste D smoothly flows along the pipe 80 to the fiber waste collection portion 66a side. Therefore, the fiber waste D can be discharged smoothly. Further, since the fiber waste outlet 77a is formed at the lower end of the peripheral wall 71a, even if the fiber waste D is temporarily discharged from the fiber waste outlet 77a, the fiber waste D is swirled and discharged again. Move near exit 77a. Therefore, it can suppress that textile waste D accumulates near the bottom 79. In this modification, the shutter 91a is configured to be able to open and close the opening 84a, but is not limited thereto. For example, the shutter 91a may be provided in the middle of the tube 80 or the like.
（５）例えば、上記（４）の変形例において、繊維屑回収部６６ａに回収された繊維屑Ｄを外部へ排出するとき、シャッタ９１ａは遮断位置に位置する。このとき、繊維屑分離部６４ａにおいて分離された繊維屑Ｄは、繊維屑回収部６６ａに回収されずに、そのまま繊維屑分離部６４ａ内に滞留することになる。すると、繊維屑分離部６４ａ内に滞留した繊維屑Ｄが繊維屑排出口７７ａの近傍に溜まって、繊維屑排出口７７ａが詰まるおそれがある。したがって、これを防止する構成を備えていても良い。図１１は、繊維屑回収システム４ｂが備える複数の繊維屑回収ユニット６１ｂの１つを示した概略図である。 (5) For example, in the modification of the above (4), when the fiber waste D collected by the fiber waste collection part 66a is discharged to the outside, the shutter 91a is located at the blocking position. At this time, the fiber waste D separated in the fiber waste separation part 64a is retained in the fiber waste separation part 64a as it is without being collected by the fiber waste collection part 66a. Then, there is a possibility that the fiber waste D retained in the fiber waste separation part 64a may be accumulated in the vicinity of the fiber waste outlet 77a and the fiber waste outlet 77a may be clogged. Therefore, a configuration may be provided to prevent this. FIG. 11 is a schematic view showing one of the plurality of fiber waste collection units 61b included in the fiber waste collection system 4b.
　繊維屑回収ユニット６１ｂの構成について説明する。繊維屑分離部６４ｂは、上記（４）の変形例の繊維屑分離部６４ａと同様の構成を有する。ブロア部６５ｂは、繊維屑分離部６４ｂに直接接続されているのではなく、セクションダクト６３ｂに接続されており、且つ、繊維屑分離部６４ｂに対して空気を送り込むように構成されている。また、この変形例では、セクションダクト６３ｂと、各空気紡績装置１２に接続されたダクト３７を合わせたものを、第１ダクト１１１とする。すなわち、第１ダクト１１１の一端部は紡績ユニット２の空気紡績装置１２に接続されており、他端部は流入口７５ｂを介して繊維屑分離部６４ｂと接続されている。また、繊維屑回収ユニット６１ｂは、第２ダクト１１２を備える。第２ダクト１１２は、一端部が繊維屑排出口７７ｂを介して繊維屑分離部６４ｂと接続されており、他端部が第１ダクト１１１の途中部と接続されている。第２ダクト１１２の途中部には、例えば、屈曲した角部１１３が設けられている。角部１１３には、開口１１４が形成されている。より具体的には、開口１１４は、角部１１３の上流側における空気及び繊維屑Ｄの流動方向の延長線上に形成されている。繊維屑回収部６６ｂは、開口１１４を介して角部１１３と接続されている。これにより、繊維屑回収部６６ｂの内部空間８３ｂは、開口１１４を介して第２ダクト１１２の内部空間１１５と連通することで繊維屑Ｄを回収可能に構成されている。シャッタ９１ｂは、開口１１４を開放することで、繊維屑回収部６６ｂの内部空間８３ｂと第２ダクトの内部空間１１５を連通させる連通位置（図１１（ａ）参照）と、開口１１４を塞ぐことで繊維屑回収部６６ｂの内部空間８３ｂと第２ダクトの内部空間１１５を遮断する遮断位置（図１１（ｂ）参照）との間で移動可能に構成されている。言い換えると、シャッタ９１ｂが連通位置にあるとき、繊維屑回収部６６ｂの内部空間８３ｂと第２ダクトが連通することで、繊維屑回収部６６ｂの内部空間８３ｂと繊維屑分離部６４ｂの内部空間７４ｂが連通している。また、シャッタ９１ｂが遮断位置にあるとき、繊維屑回収部６６ｂの内部空間８３ｂと第２ダクトが遮断されることで、繊維屑回収部６６ｂの内部空間８３ｂと繊維屑分離部６４ｂの内部空間７４ｂが遮断されている。なお、シャッタ９１ｂは、前記までの実施形態で示したようにエアシリンダで動作可能に構成されていても良いが、例えば、モータ９７（図１１（ａ）参照）によって動作可能に構成されていても良い。或いは、シャッタ９１ｂは、手動式のものであっても良い。 The configuration of the fiber waste collection unit 61b will be described. The fiber waste separation part 64b has the same configuration as the fiber waste separation part 64a of the modification of the above (4). The blower portion 65b is not directly connected to the fiber waste separation part 64b, but is connected to the section duct 63b, and is configured to feed air to the fiber waste separation part 64b. Further, in this modification, a combination of the section duct 63 b and the duct 37 connected to each pneumatic spinning device 12 is taken as a first duct 111. That is, one end of the first duct 111 is connected to the air spinning device 12 of the spinning unit 2, and the other end is connected to the fiber waste separation portion 64b via the inflow port 75b. In addition, the fiber waste collection unit 61 b includes a second duct 112. One end of the second duct 112 is connected to the fiber waste separation part 64 b via the fiber waste outlet 77 b, and the other end is connected to the middle part of the first duct 111. For example, a bent corner 113 is provided in the middle of the second duct 112. An opening 114 is formed in the corner portion 113. More specifically, the opening 114 is formed on the extension of the flow direction of the air and the fiber waste D on the upstream side of the corner portion 113. The fiber waste collection unit 66 b is connected to the corner 113 via the opening 114. Thereby, the internal space 83b of the fiber waste collection part 66b is configured to be able to collect the fiber waste D by communicating with the internal space 115 of the second duct 112 through the opening 114. The shutter 91b closes the opening 114 by opening the opening 114, thereby closing the communication position (see FIG. 11A) that causes the internal space 83b of the fiber waste collection portion 66b to communicate with the internal space 115 of the second duct. It is configured to be movable between the internal space 83b of the fiber waste collection part 66b and the shutoff position (see FIG. 11B) that shuts off the internal space 115 of the second duct. In other words, when the shutter 91b is in the communication position, the internal space 83b of the fiber waste collection part 66b and the second duct communicate with each other, whereby the internal space 83b of the fiber waste collection part 66b and the internal space 74b of the fiber waste separation part 64b Are in communication. Further, when the shutter 91b is in the blocking position, the internal space 83b of the fiber waste collection part 66b and the second duct are closed off, whereby the internal space 83b of the fiber waste collection part 66b and the internal space 74b of the fiber waste separation part 64b. Is blocked. Although the shutter 91b may be configured to be operable by the air cylinder as described in the above embodiments, for example, the shutter 91b is configured to be operable by the motor 97 (see FIG. 11A). Also good. Alternatively, the shutter 91 b may be manual.
　以上の構成を有する繊維屑回収ユニット６１ｂにおいて、ブロア部６５ｂの動作によって、繊維屑Ｄを含んだ空気が繊維屑分離部６４ｂの内部空間７４ｂに送り込まれる。内部空間７４ｂには、前記までの実施形態と同様に旋回流が発生し、繊維屑Ｄが空気と分離される。シャッタ９１ｂが連通位置に位置している場合（図１１（ａ）参照）、分離された繊維屑Ｄは、第２ダクト１１２の内部空間１１５を通って、開口１１４を介して繊維屑回収部６６内に回収される。なお、一部の繊維屑Ｄが回収され損なった場合、当該繊維屑Ｄは、そのまま第２ダクト１１２の内部空間１１５を通って第１ダクト１１１の途中部に戻り、流入口７５ｂから再び繊維屑分離部６４ｂ内に流入する。このように、第１ダクト１１１及び第２ダクト１１２によって、繊維屑Ｄの還流経路が形成される。一方、シャッタ９１ｂが遮断位置に位置している間（図１１（ａ）参照）、分離された繊維屑Ｄは、繊維屑回収部６６ｂには回収されないが、上記還流経路を通って循環する。このため、繊維屑分離部６４ｂ内に繊維屑Ｄが滞留しにくくなる。したがって、繊維屑排出口７７ｂが詰まることを防止できる。 In the fiber waste collection unit 61b having the above configuration, air including the fiber waste D is fed into the internal space 74b of the fiber waste separation part 64b by the operation of the blower unit 65b. In the internal space 74b, a swirling flow is generated as in the embodiments described above, and the fiber waste D is separated from the air. When the shutter 91b is located at the communication position (see FIG. 11A), the separated fiber waste D passes through the internal space 115 of the second duct 112, and the fiber waste collection portion 66 via the opening 114. It will be collected inside. In addition, when a part of the fiber waste D is recovered and lost, the fiber waste D returns to the middle part of the first duct 111 through the internal space 115 of the second duct 112 as it is, and the fiber waste D again from the inflow port 75b. It flows into the separation part 64b. Thus, the first duct 111 and the second duct 112 form a reflux path for the fiber waste D. On the other hand, while the shutter 91b is in the blocking position (see FIG. 11A), the separated fiber waste D is not collected by the fiber waste collection part 66b, but is circulated through the reflux path. For this reason, it becomes difficult to retain textile waste D in textile waste separation part 64b. Therefore, clogging of the fiber waste discharge port 77b can be prevented.
（６）前記までの実施形態において、繊維屑回収システム４が複数の繊維屑回収ユニット６１を備え、各繊維屑回収ユニット６１が繊維屑回収部６６を有するものとしたが、これには限られない。例えば、図１２に示すように、繊維屑回収システム４ｃが、複数の繊維屑分離部６４と複数のブロア部６５とを備え、これらに共通の繊維屑回収部６６ｃを有していても良い。この変形例において、繊維屑回収部６６ｃと複数の繊維屑分離部６４との間には、複数の繊維屑分離部６４に共通のダクト１２１が設けられている。また、繊維屑回収システム４ｃは、ダクト１２１内の空気及び繊維屑Ｄを流動させるためのブロア部１２２を有する。ブロア部１２２は、ダクト１２１内に気流を発生させ、ダクト１２１内の繊維屑Ｄを繊維屑回収部６６ｃ側に流動させる。これにより、各繊維屑分離部６４によって分離された繊維屑Ｄが、繊維屑回収部６６ｃ内に回収される。したがって、繊維屑分離部６４毎に繊維屑回収部６６が設けられている場合と比べて、繊維屑回収部６６ｃに回収された繊維屑Ｄの排出の手間を省くことができる。 (6) In the embodiments described above, the fiber waste collection system 4 includes the plurality of fiber waste collection units 61, and each fiber waste collection unit 61 includes the fiber waste collection unit 66, but the present invention is limited thereto. Absent. For example, as shown in FIG. 12, the fiber waste collection system 4c may include a plurality of fiber waste separation parts 64 and a plurality of blower parts 65, and may have a common fiber waste collection part 66c. In this modification, a common duct 121 for the plurality of fiber waste separation parts 64 is provided between the fiber waste collection part 66 c and the plurality of fiber waste separation parts 64. In addition, the fiber waste collection system 4 c has a blower unit 122 for flowing the air in the duct 121 and the fiber waste D. The blower unit 122 generates an air flow in the duct 121, and causes the fiber waste D in the duct 121 to flow toward the fiber waste collection unit 66c. Thereby, the fiber waste D separated by each fiber waste separation part 64 is collect | recovered in the fiber waste collection | recovery part 66c. Therefore, compared with the case where the fiber waste collection part 66 is provided for every fiber waste separation part 64, the effort of discharge of the fiber waste D collected by the fiber waste collection part 66c can be saved.
（７）繊維屑回収部６６内の繊維屑Ｄが繊維屑分離部６４内に逆流することを防止するため、分離された繊維屑Ｄを繊維屑回収部６６に回収しているときには、シャッタ９１を連通位置に位置させ、且つ、繊維屑回収部６６を密閉状態にしておく必要がある。また、繊維屑回収部６６から外部へ繊維屑Ｄを排出する際には、シャッタ９１を遮断位置に位置させた上で、繊維屑回収部６６を開放状態にする必要がある。これらの作業をオペレータが行う場合、誤って、シャッタ９１を開放位置に位置させ、且つ、繊維屑回収部６６を開放状態にしてしまうことを防ぐために、一例として、繊維屑回収ユニットが以下の構成を備えていても良い。例えば、図１３（ａ）に示すように、繊維屑回収ユニット６１ｄが、回収扉８５、８６の開閉状態を検知するセンサ９５を有しており、センサ９５が、回収システム制御部６２と電気的に接続されていても良い。回収システム制御部６２は、シャッタ９１が遮断位置に位置しており、且つ、繊維屑回収部６６が開放状態であるときに、シャッタ９１の遮断位置から連通位置への移動を禁止する。すなわち、回収システム制御部６２は、センサ９５の検知結果に基づき、回収扉８５、８６が開放位置に位置しているときに、シャッタ９１の位置を遮断位置に維持する。或いは、例えば、図１３（ｂ）に示すように、繊維屑回収ユニット６１ｅが、回収扉８５、８６を施錠・開錠可能に構成された電磁ロック９６を有しており、電磁ロック９６が、回収システム制御部６２と電気的に接続されていても良い。この構成において、回収システム制御部６２は、繊維屑回収部６６が密閉状態であり、且つ、シャッタ９１が連通位置に位置しているときに、電磁ロック９６を制御して回収扉８５、８６を施錠し、回収扉８５、８６が閉止位置から開放位置へ移動できないようにする。つまり、回収システム制御部６２は、繊維屑回収部６６が密閉状態から開放状態へ状態変更することを禁止する。この場合、回収システム制御部６２は、本発明の回収制御部として機能する。或いは、図示を省略するが、センサ９５及び電磁ロック９６の両方が設けられた構成になっていても良い。以上のような構成により、ブロア部６５の動作中に、外部の空気が繊維屑排出口７７を通じて繊維屑分離部６４に流れ込んで繊維屑Ｄが逆流することを抑制できる。 (7) The shutter 91 is used to collect the separated fiber waste D into the fiber waste collection part 66 in order to prevent the fiber waste D in the fiber collection part 66 from flowing back into the fiber separation part 64. Is required to be in the communication position, and the waste fiber recovery section 66 must be in a closed state. Moreover, when discharging the fiber waste D from the fiber waste collection part 66 to the outside, it is necessary to make the fiber waste collection part 66 in the open state after positioning the shutter 91 at the blocking position. When the operator performs these operations, in order to prevent the shutter 91 from being erroneously positioned at the open position and the fiber debris recovery unit 66 from being opened, the configuration of the fiber debris recovery unit has the following configuration. May be provided. For example, as shown in FIG. 13A, the fiber debris recovery unit 61d has a sensor 95 for detecting the open / close state of the recovery doors 85 and 86, and the sensor 95 is electrically connected to the recovery system control unit 62. It may be connected to The collection system control unit 62 prohibits the movement of the shutter 91 from the blocking position to the communication position when the shutter 91 is at the blocking position and the fiber waste collecting unit 66 is in the open state. That is, based on the detection result of the sensor 95, the collection system control unit 62 maintains the position of the shutter 91 at the blocking position when the collection doors 85 and 86 are at the open position. Alternatively, for example, as shown in FIG. 13 (b), the fiber waste collection unit 61 e has an electromagnetic lock 96 configured to be able to lock and unlock the collection doors 85 and 86, and the electromagnetic lock 96 is It may be electrically connected to the recovery system control unit 62. In this configuration, the collection system control unit 62 controls the electromagnetic lock 96 to set the collection doors 85 and 86 when the fiber waste collection unit 66 is in the closed state and the shutter 91 is in the communication position. Lock the lock so that the recovery doors 85 and 86 can not move from the closed position to the open position. That is, the collection system control unit 62 prohibits the fiber waste collection unit 66 from changing the state from the closed state to the open state. In this case, the recovery system control unit 62 functions as a recovery control unit of the present invention. Alternatively, although not shown, both the sensor 95 and the electromagnetic lock 96 may be provided. With the above-described configuration, it is possible to suppress external air from flowing into the fiber waste separation part 64 through the fiber waste outlet 77 and backflow of the fiber waste D during the operation of the blower part 65.
（８）前記までの実施形態において、紡績機１が繊維屑回収システム４を備えるものとしたが、他の繊維機械に繊維屑回収システム４を適用しても良い。例えば、図１５に示すような、糸Ｙａを巻取ボビンＢｍに巻き取ってパッケージＰａを形成する巻取ユニット２０２が複数錘並べられて構成される自動ワインダに、繊維屑回収システム４を適用しても良い。すなわち、繊維屑回収システム４は、上述した繊維屑Ｄ（紡績前の繊維の屑）に限らず、紡績済みの糸屑（後述する繊維屑Ｄａ）を回収しても良い。詳細な説明は省略するが、巻取ユニット２０２は、紡績済みの糸Ｙａが巻かれた給糸ボビンＢｋを供給可能に構成された給糸部２１１と、糸継装置２１４を有し、給糸ボビンＢｋから解舒された糸Ｙａに対し糸継ぎ等の各種処理を行う処理部２１２と、糸Ｙａを巻取ボビンＢｍに巻き取る巻取部２１３等を備える。給糸部２１１の近傍には、糸Ｙａの解舒に伴い発生する繊維屑Ｄａを吸引する吸引部２２１と、吸引部２２１と連通するダクト２２２とが配置されている。また、処理部２１２は、糸継ぎ時に糸Ｙａを糸継装置２１４に案内し、且つ、糸継ぎ時に発生する繊維屑Ｄａを吸引する中空のサクションアーム２３１、２３２を有する。サクションアーム２３１、２３２の先端部は、ダクト２３３、２３４とそれぞれ連通している。ダクト２２２、２３３、２３４は、セクションダクト６３に接続されている。なお、ダクト２３３、２３４とセクションダクト６３の間には、ダクト２３３、２３４とセクションダクト６３を連通・遮断させるためのバルブ２３５が設けられている。 (8) In the embodiments described above, the spinning machine 1 is provided with the fiber waste collection system 4, but the fiber waste collection system 4 may be applied to other textile machines. For example, as shown in FIG. 15, the fiber waste collection system 4 is applied to an automatic winder configured by arranging a plurality of winding units 202 that wind the yarn Ya around the winding bobbin Bm to form the package Pa. It is good. That is, the fiber waste collection system 4 may collect not only the fiber waste D (the fiber waste before spinning) but also the spun yarn waste (fiber waste Da described later). Although the detailed description is omitted, the winding unit 202 has a yarn supplying unit 211 configured to be able to supply a yarn supplying bobbin Bk on which a spun yarn Ya is wound, and a yarn joining device 214. The processing unit 212 performs various processes such as yarn splicing on the yarn Ya unwound from the bobbin Bk, and a winding unit 213 that winds the yarn Ya around the winding bobbin Bm. In the vicinity of the yarn feeding unit 211, a suction unit 221 for suctioning the fiber waste Da generated with the unwinding of the yarn Ya, and a duct 222 communicating with the suction unit 221 are disposed. The processing unit 212 also has hollow suction arms 231 and 232 for guiding the yarn Ya to the yarn joining device 214 at the time of yarn joining and for sucking the fiber waste Da generated at the time of yarn joining. The tips of the suction arms 231, 232 communicate with the ducts 233, 234, respectively. The ducts 222, 233, 234 are connected to the section duct 63. A valve 235 is provided between the ducts 233 and 234 and the section duct 63 for connecting and blocking the ducts 233 and 234 and the section duct 63.
　巻取ユニット２０２は、給糸部２１１の給糸ボビンＢｋから糸Ｙａを解舒し、巻取部２１３において巻取ボビンＢｍに糸Ｙａを巻き取ってパッケージＰａを形成する。この変形例においては、上記動作が、本発明の糸処理に相当する。特に、給糸部２１１において、糸Ｙａが解舒される際に常時繊維屑Ｄａが発生するため、巻取ユニット２０２の上記糸処理中に、吸引部２２１からダクト２２２及びセクションダクト６３に繊維屑Ｄが常時流れ込む。このような巻取ユニット２０２に、繊維屑回収システム４を適用することは有効である。 The winding unit 202 unwinds the yarn Ya from the yarn feeding bobbin Bk of the yarn feeding unit 211, and winds the yarn Ya around the winding bobbin Bm in the winding unit 213 to form a package Pa. In this variation, the above operation corresponds to the yarn processing of the present invention. In particular, since the fiber waste Da is always generated when the yarn Ya is unwound in the yarn supplying unit 211, the fiber waste from the suction unit 221 to the duct 222 and the section duct 63 during the above-described yarn processing of the winding unit 202 D always flows in. It is effective to apply the fiber waste collection system 4 to such a winding unit 202.
