Description

本発明は、綾巻きパッケージを製作する繊維機械の作業位置の糸捕集ノズルにおける負圧を制御するための装置であって、糸捕集ノズルが、繊維機械自体の負圧桁に接続されている形式のものに関する。   The present invention is an apparatus for controlling a negative pressure in a yarn collecting nozzle at a working position of a textile machine that manufactures a spiral wound package, and the yarn collecting nozzle is connected to a negative pressure girder of the textile machine itself. It is related to the format.

綾巻きパッケージを製作する繊維機械、たとえば自動綾巻きパッケージ製作機械の作業位置は、様々な糸処理・糸取扱装置を備えている。このような装置によって、一般的に比較的小容量の紡績コップとして提供される複数のボビンは、比較的多くのヤーン材料を有する綾巻きパッケージに巻き返すことができる。糸は、巻返過程の間、同時に場合によっては生じる糸エラーに関して監視され、糸エラーは場合によっては切断除去され、ほとんど同じヤーンの糸撚り繋ぎによって補償される。このために繊維機械の個々の作業位置は、たとえば巻取装置と、巻取パッケージを回動可能に保持するためのボビンフレームと、パッケージ駆動ドラムと、糸綾振り装置とを備えている。さらにそのような作業位置は、通常、下糸センサと、糸緊張装置と、糸切断装置を有する糸クリアラと、糸張力センサと、糸捕集ノズルと、パラフィン処理装置とを備えている。   The working position of a textile machine for producing a traverse package, for example, an automatic traverse package production machine, includes various yarn processing / yarn handling devices. With such an apparatus, a plurality of bobbins, typically provided as a relatively small volume spinning cup, can be rewound into a twill package having a relatively large amount of yarn material. The yarn is monitored during the rewinding process at the same time for possible yarn errors, which are possibly cut off and compensated by yarn twisting of almost the same yarn. For this purpose, each working position of the textile machine includes, for example, a winding device, a bobbin frame for holding the winding package in a rotatable manner, a package drive drum, and a yarn traversing device. Further, such a working position usually includes a lower thread sensor, a yarn tensioning device, a yarn clearer having a yarn cutting device, a yarn tension sensor, a yarn collecting nozzle, and a paraffin processing device.

破損した糸または制御された糸クリアラによる切断によって分断された糸を繋ぐために、作業位置は、追加的に糸繋ぎ装置、吸込管ならびにグリッパ管を備えている。この場合吸込管およびグリッパ管は、機械自体の負圧桁に接続されていて、かつ必要な場合、公知のように、綾巻きパッケージもしくはボビンによって受け取られた糸端部を糸繋ぎ装置に向かって搬送する。   The working position additionally comprises a threading device, a suction tube and a gripper tube for joining broken yarns or yarns that have been separated by cutting with a controlled yarn clearer. In this case, the suction pipe and the gripper pipe are connected to the negative pressure girder of the machine itself and, if necessary, the yarn end received by the twill package or bobbin towards the yarn splicer as is known. Transport.

パラフィン処理装置の領域に、追加的に、負圧桁に接続され、かつ走行する糸に向けられた糸捕集ノズルが配置されている。このような糸捕集ノズルは、巻取プロセスの間常に糸から塵埃粒子および汚染粒子を吸い込むことによって、綾巻きパッケージの品質を改善する。さらに糸捕集ノズルは、糸破断の場合に直ちに糸端部を吸い込んで、いわゆる鼓状巻き（Trommelwickel）の形成を防止する役割を担っている。   In the area of the paraffin processing device, additionally, a yarn collecting nozzle connected to the negative pressure girder and directed to the running yarn is arranged. Such a yarn collection nozzle improves the quality of the traverse package by drawing dust particles and contaminant particles from the yarn at all times during the winding process. Further, the yarn collecting nozzle plays a role of sucking the yarn end immediately in case of yarn breakage and preventing the formation of so-called drum winding (Trommelwickel).

糸破断または糸切断に続く糸撚り繋ぎ過程の間、もちろん糸捕集ノズルは負圧で負荷しないよう所望される。なぜならばそうでないと、吸込管もしくはグリッパ管によって糸繋ぎ装置の領域に引き戻された、依然として僅かに緊張された糸が誤って糸捕集ノズルに吸い込まれる、というリスクが生じるからである。   During the yarn twisting process following yarn breaking or yarn cutting, it is of course desirable that the yarn collecting nozzle not be loaded with negative pressure. This is because otherwise there is a risk that the yarn which has been pulled back into the area of the yarn splicer by the suction pipe or gripper pipe and which is still slightly strained will be accidentally sucked into the yarn collecting nozzle.

これに関して既に公知で、たとえばドイツ連邦共和国特許第１９５２８４６２号明細書に記載されているように、糸捕集ノズルの開口領域に、旋回可能に支承されたフラップが配置されており、フラップは巻取過程の間、糸捕集ノズルの開口の手前に移動される。この公知の装置の欠点によれば、フラップを作動させるために比較的手間の掛かる作動機構が必要である。
ドイツ連邦共和国特許第１９５２８４６２号明細書 As is known in this regard, for example as described in DE 195 28 462, a swivelable flap is arranged in the opening area of the yarn catching nozzle, the flap being wound up. During the process, it is moved just before the opening of the yarn collecting nozzle. Due to the disadvantages of this known device, a relatively laborious actuation mechanism is required to actuate the flap.
German Patent No. 19528462

したがって本発明の課題は、冒頭で述べたような形式の、綾巻きパッケージを製作する繊維機械の作業位置の糸捕集ノズルにおける負圧を制御するための装置を改良して、糸捕集ノズルの経済的で保守の不要な制御を実現するようなものを提供することである。   Accordingly, an object of the present invention is to improve a device for controlling a negative pressure in a yarn collecting nozzle at a working position of a textile machine for manufacturing a twill-winding package of the type described at the beginning, and to improve the device. It is to provide something that realizes economical and maintenance-free control.

この課題を解決するための本発明の装置によれば、糸捕集ノズルが、空気分岐体を介して、繊維機械の負圧桁に接続されており、空気分岐体が、糸捕集ノズルのための接続管片と、閉鎖可能な放圧管片とを備えている。   According to the apparatus of the present invention for solving this problem, the yarn collecting nozzle is connected to the negative pressure girder of the textile machine via the air branching body, and the air branching body is connected to the yarn collecting nozzle. A connecting pipe piece and a pressure-release pipe piece that can be closed.

本発明の装置によれば、簡単で複雑でない構造を有していて、極めて確実に作動するだけでなく、ほとんど保守の必要がない。糸捕集ノズルは、空気分岐体を介して、繊維機械自体の、負圧で負荷された負圧桁に接続されており、空気分岐体は、糸捕集ノズルのための接続管片と、閉鎖可能な放圧管片とを備えている。本発明による空気分岐体によって、一方では、巻き取り過程の間、糸捕集ノズルの開口に常に負圧が生じて、ひいては糸捕集ノズルが常に作動中であるよう保証され、また他方では巻取位置の吸込管が巻取中断時に上糸を受け取るために綾巻きパッケージの領域に旋回され、糸捕集ノズルが放圧管片の解放によって自動的に非作動状態にもたらされるよう保証される。   The device according to the invention has a simple and uncomplicated structure and works very reliably and requires little maintenance. The yarn collecting nozzle is connected to the negative pressure girder of the textile machine itself, which is loaded with negative pressure, through the air branching body, and the air branching body includes a connecting pipe piece for the yarn collecting nozzle, And a pressure-release pipe piece that can be closed. The air branch according to the invention, on the one hand, ensures that a negative pressure is always produced at the opening of the yarn collecting nozzle during the winding process, which in turn ensures that the yarn collecting nozzle is always in operation, and on the other hand, the winding. The suction tube at the take-up position is swung into the traverse package area to receive the upper thread when winding is interrupted, ensuring that the yarn collecting nozzle is automatically brought into an inactive state by releasing the pressure relief piece.

請求項２に記載したように、空気分岐体の放圧管片は、糸捕集ノズルのための接続管片の内法横断面よりも著しく大きな内法横断面を有している。そのような構成の結果として、通常の巻取過程の間、接続管片ひいては糸捕集ノズルの開口に、絶えず比較的大きな負圧が作用しており、このことは走行する糸の除塵にポジティブに作用する。放圧管片が解放されると、直ちに接続管片における負圧は急速に解消されるか、もしくは接続管片における負圧はほぼ完全に消滅する。これによって糸捕集ノズルは事実上非作動状態になる。   According to a second aspect of the present invention, the pressure relief pipe piece of the air branching body has an internal cross section that is significantly larger than the internal cross section of the connection pipe piece for the yarn collecting nozzle. As a result of such a configuration, during the normal winding process, a relatively large negative pressure constantly acts on the connecting tube piece and thus on the opening of the yarn collecting nozzle, which is positive for dust removal of the running yarn. Act on. As soon as the pressure relief pipe piece is released, the negative pressure in the connecting pipe piece is quickly eliminated, or the negative pressure in the connecting pipe piece disappears almost completely. This effectively deactivates the yarn collection nozzle.

請求項３および請求項４に記載したように、放圧管片は、通常の巻取過程の間、作業位置の、旋回可能に支承された吸込管によって閉鎖されるようになっている。このために放圧管片の開口は、吸込管の形状に適合されており、吸込管が待機位置で放圧管片をほぼ気密に閉鎖するようになっている。   As described in claim 3 and claim 4, the pressure relief tube piece is closed by a pivotally supported suction tube in the working position during the normal winding process. For this purpose, the opening of the pressure relief pipe piece is adapted to the shape of the suction pipe, and the suction pipe closes the pressure relief pipe piece almost airtightly at the standby position.

図１には、綾巻パッケージを製作する繊維機械、たとえばいわゆる自動綾巻パッケージ製作機械１を示した。図示の自動綾巻きパッケージ製作機械１は、エンドフレーム（図示していない）の間に同形の多数の作業位置２を備えている。作業位置２で、公知であって、したがって詳しい説明は省略するが、リング精紡機（図示していない）で生産された、比較的少ないヤーン材料を有する紡績コップ９が大容量の綾巻パッケージ１１に巻き返される。完成した綾巻きパッケージ１１は、次いで自動式のサービスユニット、たとえば綾巻きパッケージ交換機によって、機械長さの綾巻きパッケージ搬送装置２１に引き渡されて、機械端部側に配置されたパッケージ貯蔵ステーションなどに搬送される。   FIG. 1 shows a textile machine for manufacturing a tram roll package, for example, a so-called automatic tram roll package production machine 1. The automatic traverse package manufacturing machine 1 shown in the figure has a plurality of isomorphous working positions 2 between end frames (not shown). At the work position 2, a spinning cup 9 having a relatively small amount of yarn material, produced by a ring spinning machine (not shown), which is known and therefore not described in detail, is a large-capacity winding package 11. Will be rolled back. The completed traverse package 11 is then transferred to a machine-length traverse package transport device 21 by an automatic service unit, for example, a traverse package changer, to a package storage station or the like disposed on the machine end side. Be transported.

一般的にそのような綾巻きパッケージ１は、さらにパッケージ・ボビン搬送システム３の構成をしたロジスティックユニットを備えている。パッケージ・ボビン搬送システム３内で、搬送皿８上を紡績コップもしくは空管３４が循環走行する。図１および図２に、ボビン搬送システム３のうち、コップ供給区間４、可逆駆動式の貯蔵区間５、巻取位置２に通じる横搬送区間６ならびにボビン戻し区間７を示した。図示したように、この場合搬送された紡績コッ９は、先ず巻取位置２における横搬送区間６の領域に存在する繰出位置１０に位置決めされて、巻き返される。このために個々の作業位置２は、公知であり、したがって単に示唆にとどめるが様々な糸処理・糸取扱装置を備えており、糸処理・糸取扱装置によって、紡績コップ９を大容量の綾巻きパッケージ１１に巻き返すことが保証されるだけでなく、糸３０を巻き返し過程の間監視して、検出した糸エラーを取り除くことが保証される。   In general, such a traverse package 1 further includes a logistic unit having the configuration of a package / bobbin transport system 3. A spinning cup or an empty tube 34 circulates on the transport tray 8 in the package / bobbin transport system 3. FIGS. 1 and 2 show a cup supply section 4, a reversible drive type storage section 5, a lateral transport section 6 leading to the winding position 2, and a bobbin return section 7 in the bobbin transport system 3. As shown in the drawing, the spinning cot 9 conveyed in this case is first positioned at the feeding position 10 existing in the region of the horizontal conveying section 6 at the winding position 2 and is rewound. For this purpose, the individual working positions 2 are known and are therefore only suggested, but are equipped with various yarn processing and yarn handling devices, which allow the spinning cup 9 to be wound in a large capacity. In addition to ensuring that the package 11 is rewound, the yarn 30 is monitored during the rewound process to ensure that detected yarn errors are removed.

公知の糸処理・糸取扱装置の１つは巻取装置であって、これには全体符号２４を設けた。巻取装置２４は、旋回軸１９を中心に可動に支承されたパッケージフレーム１８、パッケージ駆動装置２６ならびに糸綾振り装置２８を備えている。   One of the known yarn processing / yarn handling devices is a winding device, which is provided with a general symbol 24. The winding device 24 includes a package frame 18, a package driving device 26, and a yarn traversing device 28 that are supported so as to be movable around a turning shaft 19.

図１に示した実施例では、巻取プロセスの間、綾巻きパッケージ１１はたとえば表面で、駆動ドラム２６に接触して、駆動ドラム２６によって摩擦接続によって連行される。この場合駆動ドラム２６の駆動は、公知のように、回転数調整可能で可逆式の駆動装置（図示していない）を介して行われる。綾巻きパッケージ１１に乗り上げる際の糸３０の綾振りは、糸綾振り装置２８によって行われ、糸綾振り装置２８は、本実施例では糸ガイドフィンガ２９を備えている。そのような糸綾振り装置は公知であり、たとえばドイツ連邦共和国特許出願公開第１９８５８５４８号明細書に詳しく記載されている。   In the embodiment shown in FIG. 1, during the winding process, the traverse package 11 is brought into contact with the drive drum 26, for example on the surface, and is entrained by the friction connection by the drive drum 26. In this case, the drive drum 26 is driven via a reversible drive device (not shown) that can adjust the rotation speed, as is well known. The yarn 30 is traversed by the yarn traversing device 28 when riding on the traversing package 11, and the yarn traversing device 28 includes a yarn guide finger 29 in this embodiment. Such yarn traversing devices are known and are described in detail, for example, in DE-A 1 858 548.

選択的な実施例では、糸綾振り装置２８はもちろん糸ガイドドラムとして形成することもできる。公知のように、そのような糸ガイドドラムは、糸３０を綾巻きパッケージ１１の端面の間で綾振りし、同時に綾巻きパッケージ１１を表面に沿って摩擦接続式に駆動する。   In an alternative embodiment, the yarn traversing device 28 can of course be formed as a yarn guide drum. As is well known, such a yarn guide drum traverses the yarn 30 between the end faces of the traverse package 11 and simultaneously drives the traverse package 11 along the surface in a frictional connection manner.

既に冒頭で述べたように、そのような作業位置２は、追加的に糸繋ぎ装置１３、有利にはニューマチック式に作動する撚り繋ぎ装置と、負圧で負荷可能な吸込管１２と、同様に負圧で負荷可能なグリッパ管２５とを備えている。この場合吸込管１２およびグリッパ管２５は、機械独自の負圧桁３２に接続されており、負圧桁３２自体は負圧源３３と接続されている。   As already mentioned at the beginning, such a working position 2 is additionally similar to the yarn joining device 13, preferably a twisting device that operates pneumatically, and the suction pipe 12 that can be loaded with negative pressure. And a gripper tube 25 that can be loaded with negative pressure. In this case, the suction pipe 12 and the gripper pipe 25 are connected to a negative pressure girder 32 unique to the machine, and the negative pressure girder 32 itself is connected to a negative pressure source 33.

さらに作業位置２は、一般的な形式で下糸センサ２２と、糸緊張装置１４と、糸切断装置１７を有する糸クリアラ１５と、糸張力センサ２０と、パラフィン処理装置１６とを備えている。さらにパラフィン処理装置１６の領域に糸捕集ノズル２３が位置決めされており、糸捕集ノズル２３は空気分岐体２７を介して同様に負圧桁３２に接続されている。空気分岐体２７は、糸捕集ノズル２３のための接続管片３５ならびに放圧管片３６を備えており、放圧管片３６は、通常の巻取運転中、吸込管１２によって閉鎖されている。   Further, the work position 2 is provided with a lower thread sensor 22, a yarn tensioning device 14, a yarn clearer 15 having a yarn cutting device 17, a yarn tension sensor 20, and a paraffin processing device 16 in a general form. Further, a yarn collecting nozzle 23 is positioned in the region of the paraffin processing device 16, and the yarn collecting nozzle 23 is similarly connected to a negative pressure girder 32 via an air branch body 27. The air branch body 27 includes a connecting pipe piece 35 for the yarn collecting nozzle 23 and a pressure releasing pipe piece 36, and the pressure releasing pipe piece 36 is closed by the suction pipe 12 during a normal winding operation.

図３〜図５から判るように、空気分岐体２７は、側方の２つのフランジ３７を備えており、フランジ３７を介して、空気分岐体２７は、ねじ３８などによって負圧桁３２に固定可能であり、この場合負圧桁３２における接続開口３９をカバーする。さらに空気分岐体２７は、たとえばチューブを介して糸捕集ノズル２３と接続されている接続管片３５と、吸込管１２によって閉鎖可能な放圧管片３６とを備えている。図４に示したように、放圧管片３６の内法横断面Ａ２は、接続管片３５の内法横断面Ａ１よりも相当程度大きくなっている。 As can be seen from FIGS. 3 to 5, the air branch body 27 includes two flanges 37 on the side, and the air branch body 27 is fixed to the negative pressure girder 32 by a screw 38 or the like via the flange 37. In this case, the connection opening 39 in the negative pressure girder 32 is covered. Furthermore, the air branching body 27 includes a connecting pipe piece 35 connected to the yarn collecting nozzle 23 via, for example, a tube, and a pressure releasing pipe piece 36 that can be closed by the suction pipe 12. As shown in FIG. 4, the internal cross section A 2 of the pressure relief pipe piece 36 is considerably larger than the internal cross section A 1 of the connection pipe piece 35.

以下に、本発明による装置の機能形式について説明する。   In the following, the functional form of the device according to the invention will be described.

図１に示したように、巻取過程の間、搬送皿８上に配置された紡績コップ９は、１横搬送区間６領域の繰出位置１０に位置決めされる。紡績コップ９から繰り出される糸３０は、綾巻きパッケージ１１に向かう経路上で、とりわけ下糸センサ２２と、糸緊張装置１４と、糸切断装置１７を有する糸クリアラ１５と、パラフィン処理装置１６とを通過する。   As shown in FIG. 1, during the winding process, the spinning cup 9 disposed on the transport tray 8 is positioned at the feeding position 10 in the one horizontal transport section 6 region. The yarn 30 fed out from the spinning cup 9 includes a lower yarn sensor 22, a yarn tensioning device 14, a yarn clearer 15 having a yarn cutting device 17, and a paraffin processing device 16 on the path toward the traverse package 11. pass.

糸綾振り装置２８によって交錯した姿勢で綾巻きパッケージ１１に乗り上げる糸３０の糸張力は、糸張力センサ２０によって監視される。さらにパラフィン処理装置１６の領域で糸走行経路に対して僅かな間隔で配置された、負圧で負荷される糸捕集ノズル２３は、常時走行する糸３０を吸い込んで、この際に汚染粒子および塵埃粒子を取り除く。   A yarn tension sensor 20 monitors the yarn tension of the yarn 30 that rides on the traverse package 11 in a posture interlaced by the yarn traverse device 28. Furthermore, the yarn collecting nozzle 23, which is arranged at a slight interval with respect to the yarn traveling path in the region of the paraffin processing device 16 and is loaded with a negative pressure, sucks the yarn 30 that always travels, Remove dust particles.

たとえば糸破断または制御された糸クリアラによる切断の結果として、１作業位置２に巻取中断が生じると、綾巻きパッケージ１１と結合されたいわゆる上糸は、先ず綾巻きパッケージに巻き取られ、綾巻きパッケージは適当な巻取ブレーキによって停止状態に制動される。紡績コップ９と結合されたいわゆる下糸は、原則として糸緊張装置１４および／または糸捕集ノズル２３に固定されたままであり、次いで負圧で負荷されたグリッパ管２５によって受け取られ、糸繋ぎ装置１３に向かって搬送される。ほぼ同時に吸込管１２は上糸を綾巻きパッケージ１１から受け取り、公知のように、上糸を糸繋ぎ装置１３の繋ぎ通路に挿入する。つまり巻取中断時に、吸込管１２は図１に示した、空気分岐体２７の放圧管片３６を気密に閉鎖する静止位置から、綾巻パッケージ１１に向かって上方旋回して、これによって放圧管片３６を解放する。このような放圧管片３６の解放によって、空気分岐体２７の内側において直ちに圧力特性および流れ特性が著しく変化する。   For example, if a winding break occurs at one work position 2 as a result of yarn breakage or controlled cutting by a controlled yarn clearer, the so-called upper yarn combined with the traverse package 11 is first wound into the traverse package and then traversed. The wound package is braked to a stop by a suitable winding brake. The so-called lower thread combined with the spinning cup 9 remains in principle fixed to the yarn tensioning device 14 and / or the yarn collecting nozzle 23 and is then received by the gripper tube 25 loaded with negative pressure, It is conveyed toward 13. At substantially the same time, the suction pipe 12 receives the upper thread from the traverse package 11 and inserts the upper thread into the splicing passage of the splicing device 13 as is known. That is, when the winding is interrupted, the suction pipe 12 turns upward toward the traverse winding package 11 from the stationary position shown in FIG. 1 where the pressure relief pipe piece 36 of the air branch body 27 is airtightly closed, and thereby the pressure relief pipe 12 Release the piece 36. By releasing the pressure release pipe piece 36 as described above, the pressure characteristic and the flow characteristic are significantly changed immediately inside the air branch body 27.

つまりこの時点まで接続管片３５ひいては糸捕集ノズル２３の開口に存在した負圧は、ほぼ完全になくなる。これによって糸捕集ノズル２３は、事実上非作動状態となる。   That is, the negative pressure existing at the connection pipe piece 35 and thus the opening of the yarn collecting nozzle 23 until this point is almost completely eliminated. As a result, the yarn collecting nozzle 23 is practically inactivated.

吸込管１２もしくはグリッパ管２５によって把持され、依然として僅かに緊張された上糸もしくは下糸は、この時点で問題なく処理することができ、しかも糸が糸捕集ノズル２３に吸い込まれるリスクは存在しない。   The upper or lower thread that is gripped by the suction pipe 12 or the gripper pipe 25 and is still slightly strained can be processed without problems at this point, and there is no risk that the thread is sucked into the thread collecting nozzle 23. .

糸が巻取装置に確実に固定されると、直ちに吸込管１２は静止位置に戻し旋回され、この場合再び放圧管片３６を閉鎖する。つまり負圧桁３２に生じる負圧は、接続管片３５を介して再び完全に糸捕集ノズル２３に作用し、走行する糸３０を所望の形式で除塵する。   As soon as the yarn is securely fixed to the winding device, the suction pipe 12 is returned to the rest position and swiveled, in which case the pressure relief pipe piece 36 is closed again. That is, the negative pressure generated in the negative pressure girder 32 completely acts on the yarn collecting nozzle 23 again through the connecting pipe piece 35, and dusts the traveling yarn 30 in a desired form.
