Description

本発明は、例えば、シート状のベロア材を所定の大きさに切断加工してなるブラシ製品と該ベロア材を切断加工したときに発生する細かい毛羽（繊維）のごみとを分離するためのサイクロン式分離装置に関する。   The present invention provides, for example, a cyclone for separating a brush product obtained by cutting a sheet-like velor material into a predetermined size and fine fluff (fiber) dust generated when the velor material is cut. The present invention relates to a type separation device.

一般に、重さ（大きさ）の異なる第１の分離対象物及び第２の分離対象物からなる混合物を第１の分離対象物と第２の分離対象物とに分離するものとしてサイクロン（サイクロン式分離装置）が知られている（例えば、特許文献１）。この特許文献１のサイクロンは、上端を蓋板で閉止した円筒部と該円筒部の下端縁に連結されるとともに下方に延在する逆円錐筒部とを有した胴体（容器本体）を備えている。円筒部の側壁には材料（混合物）を供給するための入口管が接線状に設けられるとともに逆円錐筒部の下端には粉粒体（第１の分離対象物）を排出するための排出管が設けられ、蓋板の中央部には該蓋板を貫通するように内筒が設けられている。   In general, a cyclone (cyclonic type) is assumed to separate a mixture of a first separation object and a second separation object having different weights (sizes) into a first separation object and a second separation object. Separation devices) are known (for example, Patent Document 1). The cyclone disclosed in Patent Document 1 includes a body (container body) having a cylindrical portion whose upper end is closed by a cover plate and an inverted conical cylindrical portion that is connected to the lower end edge of the cylindrical portion and extends downward. Yes. An inlet pipe for supplying a material (mixture) is tangentially provided on the side wall of the cylindrical portion, and a discharge pipe for discharging a granular material (first separation object) at the lower end of the inverted conical cylindrical portion. And an inner cylinder is provided at the center of the cover plate so as to penetrate the cover plate.

内筒は、円筒部の中心軸線に沿って垂下し、その下端開口から微粉末（第２の分離対象物）を排出するものであり、該内筒の上端に微粉末の流出路となる流出管が接続されている。そして、流出管から胴体内を吸引した状態で入口管から円筒部の接線方向に材料を流入させると、該材料が胴体内部を旋回する。これにより、材料のうち重い（大きい）粉粒体が旋回しながら下降して排出管から排出される一方、材料のうち軽い（小さい）微粉末が空気とともに内筒の下端開口に取り込まれて流出管から排出されることで、粉粒体と微粉末とに分離される。   The inner cylinder hangs down along the central axis of the cylindrical portion, and discharges the fine powder (second separation object) from the lower end opening, and the outflow that becomes the outflow path of the fine powder at the upper end of the inner cylinder The tube is connected. Then, when the material is caused to flow in the tangential direction of the cylindrical portion from the inlet pipe while the body is sucked from the outflow pipe, the material turns inside the body. As a result, the heavy (large) granular material of the material descends while swirling and is discharged from the discharge pipe, while the light (small) fine powder of the material is taken into the lower end opening of the inner cylinder together with the air and flows out. By being discharged from the tube, it is separated into a granular material and a fine powder.

特開２００１−２０５１３８号公報JP 2001-205138 A

ところで、特許文献１のサイクロンでは、流出管からの吸引力が小さすぎると排出管から粉粒体に混じって微粉末が排出される一方、流出管からの吸引力が大きすぎると排出管から粉粒体が排出されずに粉粒体と微粉末とが胴体内を旋回し続けるため、流出管からの吸引力の調節が難しく、場合によっては粉粒体と微粉末とを分離することができないことがあった。   By the way, in the cyclone of patent document 1, when the suction force from an outflow pipe is too small, it mixes with a granular material from a discharge pipe, On the other hand, when the suction force from an outflow pipe is too large, powder from a discharge pipe Since the granules and fine powder continue to swirl in the fuselage without discharging the granules, it is difficult to adjust the suction force from the outflow pipe, and in some cases, the granules and fine powder cannot be separated. There was a thing.

The upper end of the suction device 36 and the suction device 36 are connected via a connection pipe 37.

次に、サイクロン式分離装置１１の作用について説明する。
さて、ブラシ製品５１と毛羽ごみ５２との混合物５３をブラシ製品５１と毛羽ごみ５２とに分離する場合には、まず、吸引装置３６を駆動する。すると、流入管２２が、吸引装置３６により、第１サイクロン１３、各長孔２３、分離室２５、連絡管２６、第２サイクロン１５、吸引管３４、接続管３７を介して吸引される。これにより、第１サイクロン１３内には、該第１サイクロン１３の内周面に沿う空気の旋回流が発生する。この旋回流は、流入管２２と第１サイクロン１３との位置関係から平面視で反時計方向に流れる。この状態で流入管２２から混合物５３を第１サイクロン１３内へ流入させると、混合物５３が空気とともに旋回流となって第１サイクロン１３内を平面視で反時計方向に流れる。 Next, the operation of the cyclonic separator 11 will be described.
When separating the mixture 53 of the brush product 51 and the fluffy garbage 52 into the brush product 51 and the fluffy garbage 52, first, the suction device 36 is driven. Then, the inflow pipe 22 is sucked by the suction device 36 through the first cyclone 13, each long hole 23, the separation chamber 25, the communication pipe 26, the second cyclone 15, the suction pipe 34, and the connection pipe 37. Thereby, a swirling flow of air along the inner peripheral surface of the first cyclone 13 is generated in the first cyclone 13. This swirling flow flows counterclockwise in plan view from the positional relationship between the inflow pipe 22 and the first cyclone 13. When the mixture 53 flows into the first cyclone 13 from the inflow pipe 22 in this state, the mixture 53 turns into a swirl flow together with air and flows in the first cyclone 13 counterclockwise in plan view.

このとき、混合物５３には空気の旋回流によって平面視で反時計方向に流れる力と重力とが作用するため、該混合物５３は螺旋状に旋回しながら徐々に下降する。そして、混合物５３の旋回流が各長孔２３と対応する位置に差し掛かると、混合物５３のうちブラシ製品５１よりも軽くて小さい毛羽ごみ５２が旋回流の遠心力等によって各長孔２３を通り抜けて分離室２５へと流れ込む。   At this time, a force that flows counterclockwise in a plan view and gravity acts on the mixture 53 due to the swirling flow of air, so that the mixture 53 gradually descends while swirling spirally. When the swirling flow of the mixture 53 reaches a position corresponding to each of the long holes 23, the fluff dust 52 that is lighter and smaller than the brush product 51 in the mixture 53 passes through each of the long holes 23 by the centrifugal force of the swirling flow. Into the separation chamber 25.

この場合、各長孔２３は隣接する混合物５３の旋回流の旋回方向（平面視で反時計方向）へのずれ量が下方に向かうほど大きくなるように延びている。すなわち、混合物５３の旋回流の旋回方向（図３及び図４において矢印で示す方向）を進行方向とした場合に、該各長孔２３は、その下端部が上端部よりも該旋回方向に沿って進んだ位置に位置するようにそれぞれ傾斜している。したがって、第１サイクロン１３内を螺旋状に旋回しながら下降する混合物５３は各長孔２３に沿って移動するため、毛羽ごみ５２は各長孔２３から分離室２５へと効率よく流れ込む。   In this case, each slot 23 extends so that the amount of deviation of the swirling flow of the adjoining mixture 53 in the swirling direction (counterclockwise in plan view) increases toward the bottom. That is, when the swirling direction of the swirling flow of the mixture 53 (the direction indicated by the arrow in FIGS. 3 and 4) is the traveling direction, each of the long holes 23 has a lower end portion along the swirling direction rather than an upper end portion. Each is inclined so as to be located at the advanced position. Accordingly, since the mixture 53 that descends while spirally turning in the first cyclone 13 moves along the long holes 23, the fluff dust 52 efficiently flows from the long holes 23 into the separation chamber 25.

一方、混合物５３のうち毛羽ごみ５２よりも重くて大きいブラシ製品５１は、各長孔２３を通り抜けることができないため、旋回しながら下降して第１サイクロン１３の下端開口部２０から製品回収箱１６に落下して回収される。これにより、混合物５３からブラシ製品５１が分離される。   On the other hand, the brush product 51 that is heavier and larger than the fluffy dust 52 in the mixture 53 cannot pass through the long holes 23, and therefore, the brush product 51 descends while turning and the product collection box 16 from the lower end opening 20 of the first cyclone 13. It is dropped and collected. Thereby, the brush product 51 is separated from the mixture 53.

また、分離室２５へ流れ込んだ毛羽ごみ５２は、連絡管２６を通って第２サイクロン１５内へ流れ込む。このとき、連絡管２６と第２サイクロン１５との位置関係から第２サイクロン１５内には、該第２サイクロン１５の内周面に沿った平面視で反時計方向に流れる空気の旋回流が発生している。したがって、第２サイクロン１５内へ流れ込んだ毛羽ごみ５２は、空気とともに旋回流となって第２サイクロン１５内を平面視で反時計方向に流れる。   Further, the fluff dust 52 that has flowed into the separation chamber 25 flows into the second cyclone 15 through the connecting pipe 26. At this time, due to the positional relationship between the communication pipe 26 and the second cyclone 15, a swirling flow of air that flows counterclockwise in a plan view along the inner peripheral surface of the second cyclone 15 is generated in the second cyclone 15. is doing. Therefore, the fluff dust 52 that has flowed into the second cyclone 15 becomes a swirl flow together with the air and flows in the second cyclone 15 counterclockwise in plan view.

このとき、毛羽ごみ５２には空気の旋回流によって平面視で反時計方向に流れる力と重力とが作用するため、該毛羽ごみ５２は螺旋状に旋回しながら徐々に下降して第２サイクロン１５の下端開口部３２からごみ箱１７に落下して回収される。一方、第２サイクロン１５内を旋回する空気は、吸引管３４に流れ込み、接続管３７を通って吸引装置３６へと流れた後、該吸引装置３６から排気される。このとき、吸引管３４に流れ込む空気に毛羽ごみ５２が混じっていたとしても、フィルタ３５の作用により毛羽ごみ５２が吸引管３４内に流れ込むことはない。   At this time, the fluff dust 52 is subjected to a counterclockwise force and gravity acting in a plan view due to the swirling flow of air, so that the fluff dust 52 gradually descends while swirling spirally. From the lower end opening 32 of the trash to the trash box 17 and collected. On the other hand, the air swirling in the second cyclone 15 flows into the suction pipe 34, flows through the connection pipe 37 to the suction apparatus 36, and is then exhausted from the suction apparatus 36. At this time, even if the fluff dust 52 is mixed in the air flowing into the suction tube 34, the fluff dust 52 does not flow into the suction tube 34 due to the action of the filter 35.

このように、サイクロン式分離装置１１を用いることで、ブラシ製品５１と毛羽ごみ５２との混合物５３をブラシ製品５１と毛羽ごみ５２とに迅速かつ確実に分離することができる。   In this way, by using the cyclonic separator 11, the mixture 53 of the brush product 51 and the fluffy garbage 52 can be quickly and reliably separated into the brush product 51 and the fluffy garbage 52.

以上詳述した実施形態によれば次のような効果が発揮される。
（１）各長孔２３がブラシ製品５１の通過を規制するとともに毛羽ごみ５２の通過を許容するため、吸引口２４ｂから分離室２５を吸引することで、ブラシ製品５１及び毛羽ごみ５２のうち毛羽ごみ５２だけを各長孔２３から分離室２５へ導くことができる。したがって、ブラシ製品５１と該ブラシ製品５１よりも小さい毛羽ごみ５２とを確実に分離することができる。 According to the embodiment detailed above, the following effects are exhibited.
(1) Since each long hole 23 regulates the passage of the brush product 51 and allows the fluff dust 52 to pass, the fluff of the brush product 51 and the fluff dust 52 is obtained by sucking the separation chamber 25 from the suction port 24b. Only the dust 52 can be guided from each slot 23 to the separation chamber 25. Therefore, the brush product 51 and the fluff dust 52 smaller than the brush product 51 can be reliably separated.

（２）各長孔２３は第１サイクロン１３の周方向に沿って複数設けられているため、第１サイクロン１３内の毛羽ごみ５２を各長孔２３から分離室２５へと円滑に導くことができる。   (2) Since a plurality of the long holes 23 are provided along the circumferential direction of the first cyclone 13, the fluff dust 52 in the first cyclone 13 can be smoothly guided from the long holes 23 to the separation chamber 25. it can.

（３）第１サイクロン１３内と分離室２５とを連通する各長孔２３は、一定方向の長さが他の方向の長さに比べて長いため、第１サイクロン１３内の毛羽ごみ５２が各長孔２３から分離室２５へ流れ込む際に該各長孔２３にブラシ製品５１が張り付いても、該各長孔２３がブラシ製品５１によって完全に塞がれ難くなる。   (3) Since each long hole 23 that communicates the inside of the first cyclone 13 and the separation chamber 25 has a longer length in a certain direction than that in other directions, the fluff dust 52 in the first cyclone 13 is Even when the brush products 51 stick to the long holes 23 when flowing into the separation chamber 25 from the long holes 23, the long holes 23 are not easily blocked by the brush products 51.

（４）混合物５３の旋回流の旋回方向（図３及び図４において矢印で示す方向）を進行方向とした場合に、該各長孔２３は、その下端部が上端部よりも該旋回方向に沿って進んだ位置に位置するようにそれぞれ傾斜している。したがって、第１サイクロン１３内を螺旋状に旋回しながら下降する混合物５３は各長孔２３に沿って移動するため、混合物５３のうちの毛羽ごみ５２だけを各長孔２３から分離室２５へ効率よく流れ込ませることができる。   (4) When the swirling direction of the swirling flow of the mixture 53 (the direction indicated by the arrows in FIGS. 3 and 4) is the traveling direction, each of the long holes 23 has a lower end portion in the swirling direction rather than an upper end portion. Each is inclined so as to be located at a position advanced along. Therefore, since the mixture 53 that descends while spirally turning in the first cyclone 13 moves along the long holes 23, only the fluff dust 52 of the mixture 53 is efficiently transferred from the long holes 23 to the separation chamber 25. Can flow well.

（５）各長孔２３は第１サイクロン１３の周方向に沿って等間隔に設けられているため、第１サイクロン１３内の混合物５３のうちの毛羽ごみ５２だけを該各長孔２３から分離室２５へ均一に導くことができる。   (5) Since each long hole 23 is provided at equal intervals along the circumferential direction of the first cyclone 13, only the fluff dust 52 in the mixture 53 in the first cyclone 13 is separated from each long hole 23. The chamber 25 can be uniformly guided.

-You may change at least one of the 1st cyclone 13 and the 2nd cyclone 15 so that it may become a cylindrical shape with a fixed diameter.

・第１の分離対象物と第２の分離対象物との組み合わせは、大きさが異なるものであれば、それらの形状や材質は任意としてもよい。この場合、各長孔２３の幅は、第１の分離対象物及び第２の分離対象物のうち小さい方のみが該各長孔２３を通過できるように設定する必要がある。   -As long as the combination of a 1st separation object and a 2nd separation object differs in size, those shapes and materials may be arbitrary. In this case, the width of each long hole 23 needs to be set so that only the smaller one of the first separation object and the second separation object can pass through each long hole 23.

・第１サイクロン１３及び第２サイクロン１５のうち少なくとも一方の軸方向は、水平面に対して傾斜していてもよい。
・第１サイクロン１３の内周面には、１つあるいは複数の突起を設けてもよい。このようにすれば、第１サイクロン１３内を旋回するブラシ製品５１が該突起にぶつかることで、落下しやすくなるため、ブラシ製品５１の回収効率を向上することができる。 -At least one axial direction among the 1st cyclone 13 and the 2nd cyclone 15 may incline with respect to a level surface.
One or a plurality of protrusions may be provided on the inner peripheral surface of the first cyclone 13. If it does in this way, since it will become easy to fall because the brush product 51 which turns in the 1st cyclone 13 collides with this protrusion, the collection | recovery efficiency of the brush product 51 can be improved.

・第１サイクロン１３の内周面に、各長孔２３を個別に囲む環状の壁部を設けてもよい。このようにすれば、各長孔２３にブラシ製品５１が張り付きにくくなるので、該各長孔２３がブラシ製品５１によって塞がれることを効果的に抑制することができる。   An annular wall portion that individually surrounds each long hole 23 may be provided on the inner peripheral surface of the first cyclone 13. In this way, the brush products 51 are less likely to stick to the long holes 23, so that the long holes 23 can be effectively prevented from being blocked by the brush products 51.

・混合物５３の旋回流の旋回方向（図３及び図４において矢印で示す方向）を進行方向とした場合に、該各長孔２３の下端部が上端部よりも該旋回方向に沿って進んだ位置に位置するように、該各長孔２３をそれぞれ湾曲させてもよい。   When the swirling direction of the swirling flow of the mixture 53 (the direction indicated by the arrow in FIGS. 3 and 4) is the traveling direction, the lower end portion of each slot 23 has advanced along the swirling direction rather than the upper end portion. The long holes 23 may be curved so as to be positioned.
