- a suction passage connected to the working unit of the textile machine;
- a negative pressure source connected to the suction passage;
Relating to suction air equipment, comprising:
本発明はさらに、このような吸込み空気設備を備えた繊維機械に関する。 The invention furthermore relates to a textile machine equipped with such a suction air installation.
例えばオートワインダまたは紡績機のような繊維機械は、同様な形式の多数の作業ユニットから成っており、これらの作業ユニットは、特にその種々様々なプロセスのために少なくとも時々、吸込み空気を必要とし、この吸込み空気は、通常、繊維機械の１つまたは複数の吸込み空気設備によって準備される。普遍妥当性を制限することなしに、簡単化のために、以下において本出願の枠内においては、ただ１つの吸込み空気設備についてだけ述べる。 A textile machine, such as an autowinder or a spinning machine, consists of a number of working units of similar type, which at least occasionally require suction air, in particular for their various processes; This suction air is usually provided by one or more suction air installations of the textile machine. Without limiting its universal validity, for the sake of simplicity, only one intake air installation will be described below within the framework of the present application.
オートワインダにおいて吸込み空気は、典型的には例えば糸捕捉兼クリーニングノズルのために使用され、この糸捕捉兼クリーニングノズルは、巻取りプロセス中に、一方では、ルーズな粒子をクリーニングし、かつ他方では、ある特定の糸切れ時に下糸を捕捉するための安全機能を果たす。つまり糸捕捉兼クリーニングノズルには、少なくとも通常作動中に連続的に吸込み空気が供給される。同様にオープンエンド紡績機のロータ皿（Rotortasse）には、通常の紡績作動中に、しかしながらまた紡績開始中に、連続的に吸込み空気が供給される。 In autowinders, suction air is typically used for example for a yarn capture and cleaning nozzle, which on the one hand cleans loose particles and on the other hand cleans loose particles during the winding process. , performs a safety function to capture the bobbin thread in the event of a certain thread breakage. This means that the yarn capture and cleaning nozzle is continuously supplied with suction air, at least during normal operation. The rotor plate of an open-end spinning machine is likewise continuously supplied with suction air during normal spinning operation, but also during the start of spinning.
種々様々な繊維機械の作業ユニットの他の作業機構は、これに対して、時々かつ比較的短時間しか作動せず、かつゆえにまた、単に一時的にしか吸込み空気を必要としない。例えば巻取り機および紡績機の吸込みノズルは、単に、糸切れ時または供給媒体の交換時または巻取りパッケージの交換時に、巻取りパッケージから上糸を収容するためにしか必要とされない。 Other working mechanisms of the working units of various textile machines, on the other hand, operate only occasionally and for relatively short periods of time, and therefore also require suction air only temporarily. For example, the suction nozzles of winders and spinning machines are only needed to receive the upper thread from the winding package in the event of a yarn break or when changing the feed medium or changing the winding package.
頻繁な糸切れ時または汚れ発生の増加時に、多くの作業ユニットが同時に吸込み空気を必要とする場合には常に、負圧は、繊維機械に沿った中央の吸込み通路の内部において急激に低下することがある。特に巻取り機において負圧は、複数の作業ユニットが、例えばパッケージ交換に基づいて同時に作動させられる場合に、急激に低下することがある。負圧力が極めて強く低下すると、繊維機械の作業ユニットの整然とした作動が脅かされる。負圧は例えば、巻取りパッケージの表面における糸端部の捜索がもはや成功しないほど低下することがある。 Whenever many working units require suction air at the same time, during frequent yarn breaks or increased dirt generation, the negative pressure can drop rapidly inside the central suction passage along the textile machine. There is. In particular in winders, the underpressure can drop rapidly if several working units are operated simultaneously, for example on the basis of a package change. If the negative pressure drops too strongly, the orderly operation of the working unit of the textile machine is threatened. The underpressure may, for example, drop to such an extent that the search for the yarn end on the surface of the winding package is no longer successful.
ゆえに本発明の第１の態様は、空気力式に搬送可能な屑を吸い出すため、および糸端部を該糸端部の糸継ぎを目的として吸い込みかつ準備するために、繊維機械の作業ユニットにおいて負圧を準備する吸込み空気設備であって、繊維機械の作業ユニットに接続された吸込み通路と、吸込み通路に接続された負圧源と、を備えた、吸込み空気設備に関する。 A first aspect of the invention therefore provides for a working unit of a textile machine for sucking out pneumatically transportable waste and for sucking and preparing yarn ends for the purpose of splicing them. The present invention relates to a suction air installation for preparing negative pressure, which comprises a suction passage connected to a working unit of a textile machine and a negative pressure source connected to the suction passage.
提案された吸込み空気設備は、追加負圧源を備えた追加吸込み設備が設けられており、該追加吸込み設備は、追加負圧源が負圧源に直列接続可能であるように、吸込み通路に接続されていることによって傑出している。 The proposed suction air installation is provided with an additional suction installation with an additional negative pressure source, the additional suction installation being connected to the suction passage in such a way that the additional negative pressure source can be connected in series with the negative pressure source. Stand out by being connected.
追加吸込み設備の追加負圧源を、吸込み空気設備の吸込み通路に直列接続するという可能性は、必要な場合に吸込み通路内において比較的高い負圧を発生させるということを可能にし、これによって作業ユニットにおける高められた要求に基づく、負圧の低下を補償することができる。したがって負圧源との追加負圧源の「直列接続」というのは、追加負圧源によって吸込み通路における負圧が高められる、追加吸込み設備の配置形態であると理解することができる。追加負圧源と負圧源とは、追加吸込み設備がオンに切り換えられた場合に、流れ方向において相前後して配置されている。 The possibility of connecting an additional negative pressure source of the additional suction installation in series with the suction duct of the suction air installation makes it possible to generate a relatively high negative pressure in the suction duct if necessary, thereby making it possible to It is possible to compensate for the drop in vacuum due to increased demands on the unit. A "series connection" of an additional negative pressure source with a negative pressure source can therefore be understood as an arrangement of the additional suction installation in which the negative pressure in the suction channel is increased by the additional negative pressure source. The additional negative pressure source and the negative pressure source are arranged one after the other in the flow direction when the additional suction installation is switched on.
これによって追加吸込み設備は、具体的な必要の場合にだけ、追加的な負圧を発生させることができる。必要がない場合には、追加吸込み設備は、エネルギを節約する休止モードにシフトさせることができる。これによって全体として追加吸込み設備は、吸込み空気設備の、コストおよびエネルギのかかる適合を省くことができ、このことは全体として、吸込み空気設備、および吸込み空気設備に接続された繊維機械を、特に安価にかつスペースを節減して構成することを可能にする。 This allows the additional suction installation to generate additional underpressure only in case of specific need. If not needed, the additional suction equipment can be shifted to an energy-saving sleep mode. As a whole, the additional suction installation can thus dispense with the costly and energy-intensive adaptation of the suction air installation, which makes the suction air installation and the textile machine connected to the suction air installation particularly inexpensive. It allows for a configuration that saves space and space.
吸込み通路との追加吸込み設備の接続形態の構成は、基本的には任意の形式で行うことができる。しかしながら本発明の特に好適な構成によれば、吸込み通路は、閉鎖可能な入口開口を介して追加吸込み設備の入口通路に、かつ閉鎖可能な出口開口を介して追加吸込み設備の出口通路に接続されており、このとき入口通路は吸込み側において、かつ出口通路は出口側において、追加負圧源に接続されていることが提案されている。 The configuration of the connection of the additional suction equipment with the suction channel can basically be carried out in any manner. However, according to a particularly preferred embodiment of the invention, the suction channel is connected to the inlet channel of the additional suction installation via a closable inlet opening and to the outlet channel of the additional suction installation via a closable outlet opening. It is proposed that the inlet channel is connected on the suction side and the outlet channel on the outlet side to an additional negative pressure source.
本発明のこの構成によれば、追加吸込み設備は、吸込み通路の一部分に平行に延びていて、かつこのとき入口通路および出口通路を介して吸込み通路に接続されている。追加負圧源が負圧源に直列接続されている流れを、必要に応じて形成するために、出口開口および入口開口は閉鎖可能であり、かつさらに追加吸込み設備が必要でない場合には、流れ損失によって吸込み通路内における負圧に損失が生じないことを保証する。必要な場合には、入口開口および出口開口への相応のアクセス可能性によって、追加吸込み設備をオンに切り換えることができ、このようにして負圧損失を補償することができる。このとき吸込み通路への入口開口および出口開口を介した追加吸込み設備の接続は、吸込み空気設備に追加吸込み設備を取り付けるための、特に簡単かつ安価な可能性である。 According to this embodiment of the invention, the additional suction installation extends parallel to a portion of the suction channel and is then connected to the suction channel via an inlet channel and an outlet channel. The outlet opening and the inlet opening can be closed in order to form a flow, in which an additional negative pressure source is connected in series with the negative pressure source, and if no additional suction equipment is required, the flow It is ensured that losses do not result in negative pressure losses in the suction passage. If necessary, with corresponding accessibility to the inlet and outlet openings, additional suction equipment can be switched on and negative pressure losses can be compensated in this way. The connection of additional suction equipment via the inlet and outlet openings to the suction duct is then a particularly simple and inexpensive possibility for fitting additional suction equipment to the suction air installation.
吸込み通路内における流れの制御、および追加吸込み設備のオンへの切換え時における追加吸込み設備による流れの制御は、基本的には任意の形式で行うことができる。しかしながら本発明の特に好適な構成によれば、出口開口の領域に、第１の閉鎖エレメントが配置されており、このとき第１の閉鎖エレメントは、出口通路を閉鎖する閉鎖位置と、吸込み通路を出口開口の領域において閉鎖する迂回位置との間において移動可能であることが提案されている。 The control of the flow in the suction duct and by the additional suction installation when it is switched on can in principle take place in any manner. However, according to a particularly advantageous embodiment of the invention, a first closing element is arranged in the region of the outlet opening, the first closing element having a closed position in which it closes the outlet channel and a closed position in which it closes the suction channel. It is proposed to be movable between a closing position and a bypass position in the area of the outlet opening.
本発明のこの構成は、本発明の別の好適な構成によって提案された構成、すなわち入口開口の領域に、第２の閉鎖エレメント、特に絞りが配置されており、このとき第２の閉鎖エレメントは、入口通路を閉鎖する閉鎖位置と、吸込み通路を入口開口の領域において閉鎖する迂回位置との間において移動可能である構成との関連において、特に簡単な形式で吸込み流を必要な場合に追加吸込み設備によって迂回させることができる。 This configuration of the invention is based on the configuration proposed by another preferred configuration of the invention, namely in the region of the inlet opening a second closing element, in particular a diaphragm, is arranged, the second closing element being , in connection with an arrangement that is movable between a closed position in which the inlet passage is closed and a detour position in which the suction passage is closed in the area of the inlet opening, in a particularly simple manner to provide an additional suction flow when required. It can be detoured depending on the equipment.
このとき第１の閉鎖エレメントおよび第２の閉鎖エレメントを介して、追加吸込み設備を通る流れだけが得られるのではなく、同時に、迂回位置における追加吸込み設備の配置によって、完全な吸込み空気流が追加吸込み設備を通して貫流案内されることが保証され、これによって追加吸込み設備の追加負圧源は、流れ方向において負圧源の上流に確実に配置されている。 Via the first closing element and the second closing element, not only a flow through the additional suction equipment is then obtained, but at the same time, due to the arrangement of the additional suction equipment in the detour position, a complete suction air flow is additionally obtained. It is ensured that the suction installation is guided through, thereby ensuring that the additional negative pressure source of the additional suction installation is located upstream of the negative pressure source in the flow direction.
これによって、追加吸込み設備によって吸込み通路内において補足的な負圧が準備されるということが確実に保証される。このとき第１の閉鎖エレメントおよび第２の閉鎖エレメントがその閉鎖位置と迂回位置との間において移動できることによって、流れ方向を決定するための補足的な調節エレメントを省くことが可能になり、これによって追加吸込み設備を、特に簡単かつ安価に吸込み通路に接続することができる。 This reliably ensures that a supplementary underpressure is provided in the suction duct by means of the additional suction equipment. The fact that the first closing element and the second closing element can then be moved between their closing position and their bypass position makes it possible to dispense with an additional regulating element for determining the flow direction, thereby making it possible Additional suction equipment can be connected to the suction channel in a particularly simple and inexpensive manner.
本発明の別の構成によれば、第２の閉鎖エレメントは、吸込み通路を入口開口の領域において閉鎖する迂回位置と、吸込み通路を開放する開放位置との間において移動可能であり、このとき入口開口と追加負圧源との間の領域に、第３の閉鎖エレメントが配置されていて、該第３の閉鎖エレメントは、入口通路を閉鎖する遮断位置と、入口通路を開放する開放位置との間において移動可能であることが提案されている。本発明のこの構成は、第２の閉鎖エレメントが、吸込み通路を開放する開放位置に、かつ第３の閉鎖エレメントが、入口通路を開放する開放位置に配置されている場合に、吸込み通路に沿った流れおよび追加吸込み設備を通る流れを生ぜしめる吸込み流を可能にすることができる。 According to a further development of the invention, the second closing element is movable between a bypass position in which it closes the suction passage in the area of the inlet opening and an open position in which it opens the suction passage, with the inlet A third closing element is arranged in the region between the opening and the source of additional negative pressure, which third closing element has a blocking position for closing the inlet passage and an open position for opening the inlet passage. It has been proposed that it be possible to move between This configuration of the invention provides that the second closing element is arranged in the open position opening the suction passage and the third closing element is arranged in the open position opening the inlet passage. A suction flow can be provided to create a flow through the additional suction equipment and through additional suction equipment.
これによって本発明のこの構成は、例えば本発明の好適な発展形態によって提案された配置形態、つまり入口開口と第３の閉鎖エレメントとの間の領域において入口通路に、篩が配置されている配置形態の場合に、篩を追加吸込み設備を介してクリーニングすることができる。このとき篩から除去することができる粒子は、追加吸込み設備を介して導かれ、かつ本発明の好適な構成によれば、出口通路に配置された排気開口を介して排出され、この排気開口は、移動可能な第４の閉鎖エレメントを用いて開閉可能である。 This configuration of the invention thereby complies with, for example, the arrangement proposed by a preferred development of the invention, i.e. an arrangement in which the sieve is arranged in the inlet channel in the region between the inlet opening and the third closing element. In this case, the sieve can be cleaned via additional suction equipment. The particles which can then be removed from the sieve are led through an additional suction installation and, according to a preferred embodiment of the invention, are discharged via an exhaust opening arranged in the outlet channel, which exhaust opening is , can be opened and closed using a movable fourth closing element.
本発明のこの構成は、篩を特に簡単かつ安価にクリーニングすることができ、このとき第４の閉鎖エレメントは、篩のクリーニングの場合にだけ開放された位置に配置されており、これによって篩からの汚れの確実な排出を可能にすることができる。その他の作動時には、この閉鎖エレメントは、排気開口を閉鎖する位置に配置されており、これによって必要な場合における追加吸込み設備を通る確実な流れを保証することができる。 This configuration of the invention makes it possible to clean the sieve particularly simply and inexpensively, with the fourth closing element being arranged in the open position only in the case of cleaning the sieve, thereby allowing the sieve to be cleaned. This enables reliable discharge of dirt. In other operating conditions, this closing element is arranged in a position that closes the exhaust opening, thereby making it possible to ensure a reliable flow through the additional suction facility if necessary.
追加負圧源の構成は、基本的には任意の形式で行うことができる。本発明の特に好適な構成によれば、追加負圧源はファンによって形成されていることが提案されている。ファンの使用は、追加吸込み設備を特に簡単かつ安価に、しかもスペースを節減して構成することを可能にし、このときファンの選択によって、必要な場合に追加的に発生させることが望ましい負圧を簡単に決定することができる。 The configuration of the additional negative pressure source can be implemented in essentially any manner. According to a particularly advantageous embodiment of the invention, it is proposed that the additional negative pressure source is formed by a fan. The use of a fan makes it possible to configure additional suction equipment particularly easily, inexpensively and space-savingly, with the selection of the fan allowing the additional vacuum to be generated when required. can be easily determined.
さらに本発明の特に好適な構成によれば、追加負圧源、特にファンの回転数は調整可能であることが提案されている。このことは、追加吸込み設備を介して種々異なった負圧を制御して発生させることを可能にする。特に好ましくは、本発明の発展形態によれば、追加負圧源の回転数調整器が、負圧センサに接続されており、この負圧センサは、自動的な負圧調整を追加吸込み設備を介して簡単に可能にする。 Furthermore, according to a particularly advantageous embodiment of the invention, it is proposed that the rotational speed of the additional negative pressure source, in particular of the fan, is adjustable. This makes it possible to generate different underpressures in a controlled manner via the additional suction equipment. Particularly preferably, according to a development of the invention, the speed regulator of the additional negative pressure source is connected to a negative pressure sensor, which negative pressure sensor is provided with additional suction equipment for automatic negative pressure regulation. Easily possible through.
吸込み空気設備における追加吸込み設備の配置は、基本的には任意の箇所において行うことができる。例えば追加吸込み設備を、吸込み空気設備の中央の吸込み通路に配置することが可能であり、この中央の吸込み通路は、個々の機械吸込み通路を介して、繊維機械の個々の作業ユニットに接続されている。中央の吸込み通路に存在している全負圧に関連して、このとき必要とあれば、中央においてオンに切換え可能な追加吸込み設備を介して、中央の吸込み通路において、補足的な負圧を発生させることができる。 The arrangement of the additional suction equipment in the suction air installation can basically take place at any location. It is possible, for example, to arrange an additional suction installation in a central suction duct of the suction air installation, which central suction duct is connected to the individual working units of the textile machine via the individual machine suction ducts. There is. In relation to the total vacuum existing in the central suction duct, if necessary, a supplementary vacuum can then be created in the central suction duct via an additional suction installation which can be switched on in the center. can be generated.
しかしながら本発明の特に好適な構成によれば、追加吸込み設備に接続された吸込み通路は、機械吸込み通路によって形成されていることが提案されている。本発明のこの構成によれば、中央の吸込み通路から繊維機械の個々の作業ユニットに通じているそれぞれの機械吸込み通路に、追加吸込み設備が対応配置されている。本発明のこの構成は、個々の作業ユニットにおいて必要な場合に個々に、追加的な負圧を発生させることができる。このとき吸込み空気設備の相応の構成は、繊維機械の個々の作業ユニットの全作動状態において十分に高い負圧が、作業ユニットの使用されるアセンブリの全負圧を作動させるために保証されているということが、特に確実な形式で保証されていることによって傑出している。 However, according to a particularly preferred embodiment of the invention, it is proposed that the suction channel connected to the additional suction installation is formed by a mechanical suction channel. According to this embodiment of the invention, additional suction equipment is assigned to each machine suction duct leading from the central suction duct to the individual working units of the textile machine. This configuration of the invention makes it possible to individually generate additional vacuum if required in the individual work units. In this case, a corresponding configuration of the suction air installation ensures that a sufficiently high underpressure in all working conditions of the individual working units of the textile machine is activated in order to activate the entire underpressure of the used assembly of working units. It stands out because it is guaranteed in a particularly reliable manner.
本発明の第２の態様は、空気力式に搬送可能な屑を吸い出すため、および糸端部を該糸端部の糸継ぎを目的として吸い込みかつ準備するために、繊維機械の作業ユニットにおいて負圧を準備する吸込み空気設備を備えた繊維機械であって、繊維機械の作業ユニットに接続された吸込み通路と、吸込み通路に接続された負圧源と、を備えた、繊維機械に関する。 A second aspect of the invention provides for a working unit of a textile machine to be equipped with a The present invention relates to a textile machine with a suction air installation for preparing pressure, the textile machine having a suction passage connected to a working unit of the textile machine and a negative pressure source connected to the suction passage.
提案された繊維機械は、吸込み空気設備が、上に記載された構成のうちの１つまたは複数の構成のように構成されていることによって傑出している。 The proposed textile machine is distinguished by the fact that the intake air installation is configured in one or more of the configurations described above.
これによって繊維機械を、特に安価にかつスペースを節減して構成することができる。それというのは、吸込み空気設備の、コストおよびエネルギのかかる適合を省くことができるからである。必要な場合に追加設備に組合せ可能／接続可能である吸込み空気設備によって、具体的な必要の場合にだけ、追加的な負圧が発生させられる。追加吸込み設備の追加負圧源を、吸込み空気設備の吸込み通路に直列接続するという可能性は、必要な場合に吸込み通路内において比較的高い負圧を発生させるということを可能にし、これによって作業ユニットにおける高められた要求に基づく、負圧の低下を補償することができる。したがって負圧源との追加負圧源の「直列接続」というのは、追加負圧源によって吸込み通路における負圧が高められる、追加吸込み設備の配置形態であると理解することができる。追加負圧源と負圧源とは、追加吸込み設備がオンに切り換えられた場合に、流れ方向において相前後して配置されている。追加的な負圧が必要ない場合には、追加吸込み設備は、エネルギを節約する休止モードにシフトさせることができる。 This allows the textile machine to be constructed particularly inexpensively and space-savingly. This is because a costly and energy-intensive adaptation of the suction air installation can be avoided. An additional negative pressure is generated only in case of specific needs by means of a suction air system which can be combined/connected to additional equipment if necessary. The possibility of connecting an additional negative pressure source of the additional suction installation in series with the suction duct of the suction air installation makes it possible to generate a relatively high negative pressure in the suction duct if necessary, thereby making it possible to It is possible to compensate for the drop in vacuum due to increased demands on the unit. A "series connection" of an additional negative pressure source with a negative pressure source can therefore be understood as an arrangement of the additional suction installation in which the negative pressure in the suction channel is increased by the additional negative pressure source. The additional negative pressure source and the negative pressure source are arranged one after the other in the flow direction when the additional suction installation is switched on. If additional vacuum is not required, the additional suction equipment can be shifted to an energy-saving sleep mode.
次に、図面を参照しながら本発明の１実施形態について詳説する。 Next, one embodiment of the present invention will be described in detail with reference to the drawings.
図１～図３に示された吸込み空気設備１において、追加設備４が、入口通路６および出口通路８を介して機械吸込み通路２に接続されており、この機械吸込み通路２を介して、ここでは図示されていない繊維機械の１つの作業ユニットが、すべての作業ユニットに負圧を供給する中央の吸込み通路に接続されている。機械吸込み通路２に追加吸込み設備４を接続するために、機械吸込み通路２には入口開口５および出口開口７が取り付けられており、この入口開口５および出口開口７には、入口通路６もしくは出口通路８が接続されている。入口通路６および出口通路８は、入口開口５もしくは出口開口７とは反対側に位置している端部において、ファン３として形成された追加負圧源に接続されている。 In the suction air installation 1 shown in FIGS. 1 to 3, an additional installation 4 is connected via an inlet channel 6 and an outlet channel 8 to the mechanical suction channel 2, via which the One working unit of the textile machine, not shown here, is connected to a central suction channel which supplies all working units with negative pressure. In order to connect additional suction equipment 4 to the machine suction channel 2, the machine suction channel 2 is fitted with an inlet opening 5 and an outlet opening 7, which inlet channel 6 or an outlet opening 7 are provided. A passage 8 is connected. The inlet duct 6 and the outlet duct 8 are connected at their ends facing away from the inlet opening 5 or the outlet opening 7 to an additional negative pressure source in the form of a fan 3 .
図１に示された通常作動時において、追加吸込み設備４がオンに切り換えられていない場合には、開放位置に配置されていて機械吸込み通路２を開放している第２の閉鎖エレメント１０、遮断位置に配置されていて入口通路６を閉鎖している第３の閉鎖エレメント１１、および閉鎖位置に配置されていて閉鎖位置において出口通路８を閉鎖しかつ吸込み通路２を開放している第１の閉鎖エレメント９は、空気流が機械吸込み通路２だけを通って矢印方向に流れることを保証する。 In the normal operation shown in FIG. 1, if the additional suction installation 4 is not switched on, the second closing element 10, which is arranged in the open position and opens the machine suction channel 2, shuts off. a third closing element 11 which is arranged in the closed position and closes the inlet passage 6; and a first closure element 11 which is arranged in the closed position and closes the outlet passage 8 and opens the suction passage 2. The closing element 9 ensures that the airflow flows only through the machine suction channel 2 in the direction of the arrow.
必要な場合、つまり追加吸込み設備４によって補助されるもしくは支援されることが望ましい、負圧低下（不足）の場合または負圧需要が増大している場合には、第１の閉鎖エレメント９、第２の閉鎖エレメント１０、および第３の閉鎖エレメント１１は、図２に示された位置に移動させられる。このとき第１の閉鎖エレメント９は、迂回位置に配置されていて、この迂回位置において出口開口７は開放され、かつ機械吸込み通路２は遮断されており、これによって追加吸込み設備４および出口開口７だけを通る流れを生ぜしめることができる。同様に、迂回位置における第２の閉鎖エレメント１０によって、吸込み空気流が入口開口５だけを通って流れることが保証されており、このとき入口通路６は、開放位置に配置された第３の閉鎖エレメント１１によって、追加吸込み設備４を通る流れを可能にする。 If necessary, i.e. in case of a vacuum drop (lack) or in the case of an increased vacuum demand, which is assisted or desired to be assisted by an additional suction facility 4, the first closing element 9, the second The second closing element 10 and the third closing element 11 are moved into the position shown in FIG. The first closing element 9 is then arranged in a bypass position, in which the outlet opening 7 is open and the machine suction channel 2 is blocked, so that the additional suction equipment 4 and the outlet opening 7 are closed. It is possible to create a flow that flows only through Similarly, the second closing element 10 in the bypass position ensures that the suction air flow flows only through the inlet opening 5, with the inlet passage 6 being connected to the third closing element 10 arranged in the open position. Element 11 allows flow through additional suction equipment 4.
入口開口５の領域に配置された篩１４のクリーニングが必要な場合には、第１の閉鎖エレメント９はその閉鎖位置に、かつ第２の閉鎖エレメント１０はその開放位置にあり、これらの位置において、機械吸込み通路２を通る流れが解放されている。同時に第３の閉鎖エレメント１１もまたその開放位置にあり、これによって吸込み空気流の一部が、追加吸込み設備４をも通って流れることができる。このとき篩１４から除去することができる汚れは、出口通路８に配置された排気開口１３を介して排出され、このとき排気開口１３は、そのために、開放位置に配置された第４の閉鎖エレメント１２によって開放される。篩クリーニングに続いて、排気開口１３を閉鎖する位置への第４の閉鎖エレメント１２の戻し移動と、および入口通路６を閉鎖する位置への第３の閉鎖エレメント１１の移動とが行われ、これによって再び通常作動を保証することができ、この通常作動においては追加吸込み設備４は不要になる。篩クリーニングは、通常、作業ユニットにおいて吸込み空気が不要な場合にしか行われない。それというのは、さもないと負圧が追加の負担によって過度に弱められてしまうからである。 If cleaning of the sieve 14 arranged in the area of the inlet opening 5 is required, the first closing element 9 is in its closed position and the second closing element 10 is in its open position; , the flow through the mechanical suction passage 2 is open. At the same time, the third closing element 11 is also in its open position, so that a part of the suction airflow can also flow through the additional suction facility 4 . The dirt that can then be removed from the sieve 14 is discharged via the exhaust opening 13 arranged in the outlet channel 8, which for this purpose is connected to the fourth closing element arranged in the open position. It is released by 12. The sieve cleaning is followed by a return movement of the fourth closing element 12 into the position of closing the exhaust opening 13 and a movement of the third closing element 11 into the position of closing the inlet passage 6, which normal operation can be ensured again, in which case the additional suction equipment 4 is no longer necessary. Sieve cleaning is normally only carried out if no suction air is required in the working unit. This is because otherwise the negative pressure would be unduly weakened by the additional load.
