Description

Die Erfindung betrifft eine Doppeldraht-Zwirnmaschine mit einer Vielzahl nebeneinander angeordneter, einen Spulentopf aufweisender Zwirnspindeln und mit einem an die einzelnen Zwirnspindeln heranstellbaren Wartungsautomaten. Eine solche Doppeldraht-Zwirnmaschine ist z.B. aus der DE-A-3 824 998 bekannt.The invention relates to a double-wire twisting machine with a plurality of twisting spindles arranged next to one another and having a bobbin and with an automatic maintenance machine that can be produced on the individual twisting spindles. Such a double wire twisting machine is e.g. known from DE-A-3 824 998.

Auf Doppeldraht-Zwirnmaschinen werden Zwirnkreuzspulen mit großer Fadenlauflänge hergestellt. Je nach Garnnummer und der damit im gewissen Zusammenhang stehenden Fadendrehung je Meter liegen die Betriebszeiten für den Ablauf einer vollen ungezwirnten Spule zwischen 4 und 44 Stunden und mehr.Cross-wound bobbins with a long thread length are produced on double-wire twisting machines. Depending on the thread number and the related thread twist per meter, the operating times for a full untwisted bobbin are between 4 and 44 hours and more.

Während so langer Laufzeiten ist entweder durch den Prozeß selbst oder aber durch weitere, der Doppeldraht-Zwirnmaschine angegliederte Arbeitsprozesse eine Verstaubung und teilweise auch eine Verschmutzung der Doppeldraht-Zwirnmaschine unvermeidlich. Es ist deshalb üblich, solche und auch andere Maschinen, z.B. Spinnmaschinen, mit Wanderblaseinrichtungen auszurüsten, die in bestimmten Zeitabständen an jeder Arbeits- bzw. Zwirnstelle vorbeikommen und durch Blas- bzw. Saugströme bestimmte Maschinenbereiche von einer zu großen Verstaubung bzw. Verschmutzung freihalten. Diese Maßnahmen sind zwar hilfreich, wobei sie jedoch bei Doppeldraht-Zwirnspindeln meistens unzureichend sind, weil durch den beim Doppeldraht-Zwirnen entstehenden Fadenballon bestimmte Maschinenbereich nicht erreicht werden können. Dieses trifft ganz besonders für den Spindelbereich und dabei speziell für den Spulentopf und den Ballonbegrenzer, aber auch für den Spindelrotor selbst zu.During such long terms, either the process itself or other, the Double wire twisting machine associated work processes inevitable dust and sometimes also contamination of the double wire twisting machine. It is therefore common to equip such and other machines, such as spinning machines, with traveling blowers, which come past every working or twisting point at certain intervals and keep certain areas of the machine free of excessive dust or contamination by blowing or suction flows. Although these measures are helpful, they are usually inadequate in the case of double-wire twisting spindles, because certain thread areas cannot be reached due to the thread balloon resulting from the double-wire twisting. This is particularly true for the spindle area and especially for the coil pot and the balloon limiter, but also for the spindle rotor itself.

Bei einem Spulenwechsel, d.h. bei einer Neubestückung einer Zwirnstelle werden deshalb oftmals die gerade benannten Bereich präventiv gereinigt. Dies geschieht häufig von Hand oder durch einfache Hilfsmittel, beispielsweise in Form von Flusenfanggeräten. Es ist jedoch auch üblich, Saug- oder Blasstutzen von Hand einzuführen.When changing bobbins, ie when re-equipping a thread, the areas just mentioned are often cleaned preventively. This is often done by hand or by simple aids, for example in the form of lint traps. However, it is also common to insert suction or blow nozzles by hand.

Bei einer in der DE-A-2 658 451 beschriebenen Offenend-Spinnmaschine ist eine längs dieser Maschine verfahrbarere Wartungseinrichtung mit einem Reinigungselement zum Reinigen des Spinnrotors jedes einzelnen Spinnaggregates ausgerüstet. Nach den Öffenen des Spinnaggregates wird diese Reinigungseinrichtung in Form einer Reinigungsbürste, die mittels einer Welle von einem Motor antreibbar ist, dem Spinnrotor von oben unter einem Winkel von etwa 45° zur Rotorachse zugestellt. Aufgrund einer von einer Doppeldraht-Zwirnspindel abweichenden Gesamtkonstruktion eines Spinnrotors einer Offenend-Spinnmaschine ist diese bekannte Wartungseinrichtung mit zugeordneter Reinigungseinrichtung nicht für den automatisierten Betrieb einer Doppeldraht-Zwirnspindel geeignet.In an open-end spinning machine described in DE-A-2 658 451, a maintenance device which can be moved along this machine is equipped with a cleaning element for cleaning the spinning rotor of each individual spinning unit. After the spinning unit has been opened, this cleaning device in the form of a cleaning brush, which can be driven by a motor by means of a shaft, is fed to the spinning rotor from above at an angle of approximately 45 ° to the rotor axis. Because of the overall construction of a spinning rotor of an open-end spinning machine that differs from a double-wire twisting spindle, this known maintenance device with an associated cleaning device is not suitable for the automated operation of a double-wire twisting spindle.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Doppeldraht-Zwirnspindel Maßnahmen vorzusehen, um insbesondere in Verbindung mit dem Austausch einer Vorlagespule die besonders gefährdeten Maschinenbereiche, nämlich Spulentopf und/oder Ballonbegrenzer und/oder Spindelrotor in einer automatisierten Verfahrensweise zu reinigen.The invention has for its object to provide measures in a double-wire twisting spindle, in particular in connection with the replacement of a supply spool, the particularly endangered machine areas, namely the bobbin and / or balloon limiter and / or spindle rotor in an automated How to clean.

Ausgehend von der Vorrichtung gemäß DE-A-3 824 998 wird diese Aufgabe durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.Starting from the device according to DE-A-3 824 998, this object is achieved by the features of the characterizing part of claim 1.

Darüber hinausgehende, bevorzugte Maßnahmen sind in Unteransprüchen behandelt.Preferred measures which go beyond this are dealt with in subclaims.

Im folgenden werden unter Bezugnahme auf die Fig. 2 bis 6 die erfindungsgemäßen ersten und zweiten Reinigungseinrichtungen beschrieben.The first and second cleaning devices according to the invention are described below with reference to FIGS. 2 to 6.

Die in Fig. 2 dargestellte erste Reinigungseinrichtung 23 dient zum Reinigen des Spulentopfes 8 einer Doppeldraht-Zwirnspindel. Diese erste Reinigungseinrichtung 23 enthält einen im Wartungsautomaten B gelagerten, auf und ab bewegbaren und um eine Vertikalachse verschwenkbaren Schwenkarm 40, durch dessen Inneres eine zu einer nicht dargestellten Saugluftquelle führende Saugluftleitung 40.1 sowie eine zu einer nicht dargestellten Druckluftquelle führende Druckluftleitung 40.2 verlaufen. An dem Ende des Schwenkarmes 40 befindet sich ein Kopfstück 40.3, in das ein vertikal nach unten gerichtetes und an die Saugluftleitung 40.1 angeschlossenes Saugmundstück 41 eingesetzt ist. Das untere Ende des rohrförmigen Saugmundstückes 41 erweitert sich trichterförmig. Durch das Saugmundstück 41 verläuft koaxial eine Arbeitswelle 42 eines auf das Kopfstück 40.3 aufgesetzten Elektromotors 43. Das untere Ende der Arbeitswelle 42 trägt ein Nabenteil 44, an dem mittels radial gerichteten, vorzugsweise verschwenkbaren Armen 45 vertikal verlaufende Bürstenleisten 46 befestigt sind.The first cleaning device 23 shown in FIG. 2 is used to clean the bobbin 8 of a double-wire twisting spindle. This first cleaning device 23 contains a swivel arm 40 which is mounted in the maintenance machine B and can be moved up and down and pivoted about a vertical axis, through the inside of which one does not become one The suction air line 40.1 leading to the suction air source shown and a compressed air line 40.2 leading to a compressed air source (not shown) run. At the end of the swivel arm 40 there is a head piece 40.3 into which a suction mouthpiece 41 is inserted, which is directed vertically downwards and is connected to the suction air line 40.1. The lower end of the tubular suction mouthpiece 41 widens in a funnel shape. A working shaft 42 of an electric motor 43 placed on the head piece 40.3 runs coaxially through the suction mouthpiece 41. The lower end of the working shaft 42 carries a hub part 44, to which vertically extending brush strips 46 are fastened by means of radially directed, preferably pivotable arms 45.

Das rohrförmige Saugmundstück 41 ist von einem sich an das Kopfstück 40.3 anschließenden Ringzylinder 40.4 umgeben, in den ein Stellorgan in Form eines Ringkolbens 47 eingesetzt ist, der mittels Dichtungsringen 48, 49 abdichtend in dem Ringzylinder 40.4 geführt ist. Oberhalb des Ringkolbens 47 befindet sich ein mit der Druckluftleitung 40.2 in Verbindung stehender Druckluftraum 50.The tubular suction mouthpiece 41 is surrounded by an annular cylinder 40.4 adjoining the headpiece 40.3, into which an actuator in the form of an annular piston 47 is inserted, which is sealingly guided in the annular cylinder 40.4 by means of sealing rings 48, 49. Above the annular piston 47 there is a compressed air space 50 connected to the compressed air line 40.2.

An der Außenseite des Saugmundstückes 41 sind mittels Laschen 51 doppelarmige Greiferhebel 52 schwenkbar gelagert. Jeder Greiferhebel 52 weist einen oberen Hebelarm 52.1, dessen Ende gegen die Unterseite des Ringkolbens 47 anliegt, sowie einen unteren Hebelarm 52.2 auf, dessen unteres freies Ende als Greifansatz 52.3 ausgestaltet ist, der zum Ergreifen des Spulentopfes 8 gegen den oberen Rand desselben zur Anlage bringbar sind.Double-armed gripper levers 52 are pivotally mounted on the outside of the suction mouthpiece 41 by means of tabs 51. Each gripper lever 52 has an upper lever arm 52.1, the end of which rests against the underside of the annular piston 47, and a lower lever arm 52.2, the lower free end of which is designed as a gripping projection 52.3 which is used to grip the bobbin 8 against the upper one Edge of the same can be brought to the plant.

Zum Reinigen des Spulentopfes 8 wird die Reinigungseinrichtung 23 aus dem Wartungsautomaten in eine zentrische Lage oberhalb der Spindelachse der Doppeldraht-Zwirnspindel verschwenkt. Anschließend wird die Reinigungseinrichtung 23 nach unten gesenkt, bis die Greifansätze 52.3 gegen den oberen Rand des Spulentopfes 8 zur Anlage kommen. Anschließend wird durch Druckluftzufuhr in den Druckraum 50 der Ringkolben 47 abgesenkt, wodurch die unteren freien Hebelarme 52.2 nach innen verschwenkt werden, so daß der Spulentopf fest erfaßt und gegen Drehen gesichert wird. Danach wird der Elektromotor 43 in Gang gesetzt, wodurch die in den Schutztopf eingeführten Bürstenleisten 46 in Drehung versetzt und an der Innenwand des Schutztopfes 8 entlanggeführt werden. Gleichzeitig wird die Saugluftleitung 40.1 an die Saug-Luftquelle angeschlossen, so daß durch das Saugmundstück 41 gegebenenfalls mit Schmutzteilen und Staubartikeln beladene Luft aus dem Spulentopf 8 abgesaugt und weggeleitet wird.To clean the bobbin 8, the cleaning device 23 is pivoted out of the maintenance machine into a central position above the spindle axis of the double-wire twisting spindle. The cleaning device 23 is then lowered until the gripping projections 52.3 come to bear against the upper edge of the bobbin pot 8. Subsequently, the annular piston 47 is lowered by supplying compressed air into the pressure chamber 50, as a result of which the lower free lever arms 52.2 are pivoted inwards, so that the coil pot is firmly gripped and secured against rotation. Thereafter, the electric motor 43 is started, whereby the brush strips 46 inserted into the protective pot are rotated and guided along the inner wall of the protective pot 8. At the same time, the suction air line 40.1 is connected to the suction air source, so that air loaded with dirt parts and dust particles is sucked out of the bobbin 8 and conducted away through the suction mouthpiece 41.

Die Bürstenleisten 46 haben eine der Höhe des Spulentopfes 8 entsprechende Länge, wobei an dem unteren Ende der Achse 42 bzw. des Nabenteils 44 gegebenenfalls radial verlaufende, nach unten gerichtete Bürstenleisten zur Reinigung des Spulentopfbodens angebracht sein können.The brush strips 46 have a length corresponding to the height of the coil pot 8, it being possible for brush strips, which may run radially downward, for cleaning the bottom of the coil pot to be attached to the lower end of the axis 42 or the hub part 44.

Nach vollendetem Reinigungs- bzw. Putzvorgang wird der in der Druckluftleitung 40.2 und in dem Druckraum 50 herrschende Druck wieder abgebaut, so daß der Ringkolben 47 unter dem Einfluß einer Rückstellfeder 53 nach oben bewegt wird, so daß die Greiferhebel 52 den Spulentopf 8 wieder freigeben. Danach wird die Reinigungseinrichtung 23 aus dem Schutztopf 8 herausgefahren, um anschließend wieder in den Bereich des Wartungsautomaten B eingeschwenkt zu werden.
Bei der sich auf Fig. 2 beziehenden Funktionsbeschreibung ist davon ausgegangen worden, daß der eigentliche Reinigungs- bzw. Putzvorgang im Bereich der Zwirnstelle, d.h. der Doppeldraht-Zwirnspindel durchgeführt wird. Es besteht jedoch auch die Möglichkeit, den Schutztopf 8 aus der Zwirnstelle bzw. Doppeldraht-Zwirnspindel herauszuheben und in den Bereich des Wartungsautomatens einzuschwenken, so daß dann der eigentliche Reinigungsvorgang innerhalb des Wartungsautomaten B durchgeführt werden kann. Dieses Herausheben des Schutztopfes 8 aus der Doppeldraht-Zwirnspindel ist schematisiert in Fig. 3 dargestellt, wobei gemäß Fig. 5 von einer Doppeldraht-Zwirnspindel mit einem aus dem Ballonbegrenzer 7 herausnehmbaren Spulentopf 8 ausgegangen wird.After the cleaning or cleaning process has been completed, the pressure prevailing in the compressed air line 40.2 and in the pressure chamber 50 is reduced again, so that the annular piston 47 under the influence of a Return spring 53 is moved upward, so that the gripper levers 52 release the bobbin 8 again. Thereafter, the cleaning device 23 is moved out of the protective pot 8 in order to then be pivoted back into the area of the maintenance machine B.
In the functional description relating to FIG. 2, it was assumed that the actual cleaning or cleaning process is carried out in the area of the twisting point, ie the double-wire twisting spindle. However, there is also the possibility of lifting the protective pot 8 out of the twisting point or double-wire twisting spindle and pivoting it into the area of the maintenance machine, so that the actual cleaning process can then be carried out within the maintenance machine B. This lifting of the protective pot 8 out of the double-wire twisting spindle is shown schematically in FIG. 3, whereby, according to FIG. 5, a double-wire twisting spindle with a bobbin 8 which can be removed from the balloon limiter 7 is assumed.

Bei dem Wartungsautomaten B kann es sich um einen solchen handeln, der neben der zuvor beschriebenen Reinigungseinrichtung 23 und einer gegebenenfalls weiteren, noch zu bescheibenden Reinigungseinrichtung 24 auch zusätzliche Wartungs- und Handhabungselemente umfaßt mit denen ein Spulen- bzw Hülsenaustausch durchgeführt werden kann.The maintenance machine B can be one which, in addition to the cleaning device 23 described above and a possibly further cleaning device 24, which is still to be described, also includes additional maintenance and handling elements with which a coil or sleeve exchange can be carried out.

Die Fig. 3 und 4 zeigen eine Anordnung, die neben einer ersten, insbesondere in Verbindung mit Fig. 2 beschriebenen Reinigungseinrichtung 23 eine weitere zweite Reinigungseinrichtung 24 umfaßt, die zur Reinigung bzw. Säuberung des Ballonbegrenzers 7 vorgesehen ist.3 and 4 show an arrangement which, in addition to a first cleaning device 23, in particular described in connection with FIG. 2, comprises a further second cleaning device 24, which is provided for cleaning or cleaning the balloon limiter 7.

Zur Fig. 3 ist vorausschickend noch zu erwähnen, daß mit dem Einschwenken einer Reinigungseinrichtung in den Bereich der Spindelachse der Ballonfadenführer 10 aus seiner koaxialen Lage zur Spindel herausgeschwenkt wird.3 it should be mentioned in advance that when the cleaning device is pivoted into the region of the spindle axis, the balloon thread guide 10 is pivoted out of its coaxial position to the spindle.

Fig. 3 zeigt den Zustand, bei dem der Spulentopf 8 von der ersten Reinigungseinrichtung 23 in Richtung des Pfeiles f2 aus dem Ballonbegrenzer 7 herausgehoben wird, um anschließend in Richtung des Pfeiles f3 in das Innere des Wartungsautomaten B verschwenkt zu werden. Nach der Herausnahme des Spulentopfes 8 aus dem Spindelbereich wird anschließend die zweite Reinigungseinrichtung 24, die an einem Schwenkarm 54 befestigt ist, in Richtung des Pfeiles f4 aus dem Wartungsautomaten B bis über die zu wartende bzw. zu reinigende Spindel herausgeschwenkt. Diese zweite Reinigungseinrichtung 24 enthält ebenfalls einen Antriebsmotor 55 zum Antrieb einer Welle 56, die einen Nabe 57 trägt, an der vertikal angeordnete Bürstenleisten 58 für die Innenwand des Ballonbegrenzers 7 befestigt sind. Die Absaugung von mit Schmutz oder Staubteilen beladener Luft kann mittels einer aus dem Wartungsautomaten B an die Fadenspeicherscheibe 19 heranstellbaren Saugdüse 59 erfolgen, oder mittels einer Saugeinrichtung, wie sie im wesentlichen in Verbindung mit Fig. 2 für die erste Saugeinrichtung 23 beschrieben ist. Fig. 4 zeigt im übrigen auch im Inneren des Wartungsautomaten B eine zusätzliche Saugdüse 60, um bei einer Reinigung des Spulentopfes 8 innerhalb des Wartungsautomaten B mit Staub- oder Schmutzteilen beladene Luft abzusaugen. Diese Saugdüse 60 kann ergänzend oder als Ersatz für die in Verbindung mit Fig.2 beschriebene Absaugeinrichtung Verwendung finden.3 shows the state in which the bobbin 8 is lifted out of the balloon limiter 7 by the first cleaning device 23 in the direction of the arrow f2, in order then to be pivoted into the interior of the maintenance machine B in the direction of the arrow f3. After removing the bobbin 8 from the spindle area, the second cleaning device 24, which is fastened to a swivel arm 54, is then pivoted out of the maintenance machine B in the direction of the arrow f4 as far as over the spindle to be serviced or cleaned. This second cleaning device 24 also contains a drive motor 55 for driving a shaft 56, which carries a hub 57, to which vertically arranged brush strips 58 for the inner wall of the balloon limiter 7 are fastened. The extraction of air laden with dirt or dust parts can be carried out by means of a suction nozzle 59 which can be brought up to the thread storage disk 19 from the maintenance machine B, or by means of a suction device, as is essentially described for the first suction device 23 in connection with FIG. 2. 4 also shows an additional suction nozzle 60 in the interior of the maintenance machine B in order to clean the coil pot 8 inside the maintenance machine B Extract air laden with dust or dirt. This suction nozzle 60 can be used in addition or as a replacement for the suction device described in connection with FIG.

Fig. 6 zeigt die spezielle Konstruktion einer erfindungsgemäßen und/oder erfindungsgemäß in Verbindung mit einem Wartungsautomaten verwendeten Reinigungseinrichtung. Die in Fig. 6 dargestellte Reinigungseinrichtung kann sowohl als Reinigungseinrichtung für den Spulentopf 8 oder als Reinigungseinrichtung für einen Ballonbegrenzer 7, wie es in Fig. 6 zum Ausdruck gebracht ist, verwendet werden.6 shows the special construction of a cleaning device according to the invention and / or according to the invention used in connection with a maintenance machine. The cleaning device shown in FIG. 6 can be used both as a cleaning device for the coil pot 8 or as a cleaning device for a balloon limiter 7, as is expressed in FIG. 6.

Bei der folgenden Beschreibung von Fig. 6 ist davon ausgegangen, daß es sich um die Reinigungseinrichtung 24 handelt, die eine angetriebene Welle 56 mit an dem Wellenende befestigter Nabe 57 aufweist, an der die Bürstenleisten 58 befestigt sind.In the following description of FIG. 6 it is assumed that it is the cleaning device 24 which has a driven shaft 56 with a hub 57 fastened to the shaft end, to which the brush strips 58 are fastened.

Um eine genaue Zentrierung der Reinigungseinrichtung innerhalb des Ballonbegrenzers 7 zu gewährleisten, ist die Nabe 57 an ihrer Unterseite mit einem Lagerblock 61 versehen, der auf das Oberteil der Spindelachse 62 aufsteckbar ist.In order to ensure precise centering of the cleaning device within the balloon limiter 7, the hub 57 is provided on its underside with a bearing block 61 which can be plugged onto the upper part of the spindle axis 62.

Die einzelne Bürstenleiste 58 ist mittels eines doppelarmigen Schwenkhebels 63 an der Nabe 57 beweglich befestigt. Jeder Schwenkhebel 63 ist um eine Horizontalachse verschwenkbar, die derart gelagert ist, daß der Schwenkhebel, bezogen auf die Spindelachse, in einer Radialebene verschwenkbar ist. Der eine untere Hebelarm 63.1 wird mittels einer Druckfeder 64 nach außen gedrückt, während an dem anderen oberen Hebelarm 52.2 die Bürstenleiste 58 angelenkt ist, und zwar im wesentlichen in der Mitte der Länge der Bürstenleiste.The individual brush strip 58 is movably attached to the hub 57 by means of a double-armed pivot lever 63. Each pivot lever 63 is pivotable about a horizontal axis, which is mounted such that the pivot lever, relative to the spindle axis, is pivotable in a radial plane is. One lower lever arm 63.1 is pressed outwards by means of a compression spring 64, while the brush strip 58 is articulated on the other upper lever arm 52.2, essentially in the middle of the length of the brush strip.

Am unteren Ende jeder Bürstenleiste 58 ist eine Materialanhäufung 58.1 angebracht bzw. vorgesehen. Diese Materialanhäufung 58.1 bewirkt, daß dann, wenn die Welle 56 und damit der Nabenkörper 57 in Drehung versetzt werden zuerst das untere Ende jeder Bürstenleiste 58 unter dem Einfluß der Fliehkraft nach außen bewegt wird, so daß auch die unteren Borsten jeder Bürstenleiste zuerst gegen die Innenwand des Ballonbegrenzers zur Anlage kommen und sich dadurch nach unten in den Spalt zwischen dem Ballonbegrenzer und dem üblichen Überlaufteller 19.1 der Fadenspeicherscheibe 19 hineinbewegen. Bei höherer Drehzahl wird dann insgesamt die Bürstenleiste 58 über ihre gesamte Länge nach außen bewegt, so daß eine Reinigung über die gesamte Ballonbegrenzerhöhe erfolgt.At the lower end of each brush strip 58, a material accumulation 58.1 is attached or provided. This accumulation of material 58.1 has the effect that, when the shaft 56 and thus the hub body 57 are set in rotation, the lower end of each brush strip 58 is first moved outward under the influence of centrifugal force, so that the lower bristles of each brush strip are first against the inner wall of the balloon limiter come to rest and thereby move down into the gap between the balloon limiter and the usual overflow plate 19.1 of the thread storage disk 19. At higher speed, the brush strip 58 is then moved outwards over its entire length, so that cleaning takes place over the entire balloon limiter height.

An der Unterseite des Nabenkörpers 57 sind weitere nach unten gerichtete Bürsten bzw. Borstenelemente 65 entweder zur Reinigung der Oberseite des Fadenüberlauftellers 19.1 oder eines Spulentopfbodens vorgesehen.On the underside of the hub body 57, further downward-pointing brushes or bristle elements 65 are provided either for cleaning the top of the thread overflow plate 19.1 or a bobbin bottom.

Sobald die Welle 56 wieder zum Stillstand konmt werden die Bürstenleisten 58 unter dem Einfluß der auf die Schwenkhebel 63 einwirkenden Druckfedern 64 wieder nach innen eingezogen.As soon as the shaft 56 comes to a standstill again, the brush strips 58 are drawn back inward under the influence of the compression springs 64 acting on the pivoting levers 63.

Der Lagerblock 61 ist innerhalb des Nabenkörpers 57 in axialer Richtung schwimmend gelagert und ist gegenüber dem Nabenkörper mittels einer axial angeordneten Druckfeder 64 abgestützt, so daß in Richtung des Doppelpfeiles f5 ein ausreichender axialer Bewegungsraum zwischen der Spindelachse 62 und der Welle 56 möglich ist, um beim Aufsetzen des Lagerblocks 61 auf die Spindelachse 62 Beschädigungen im Bereich der Spindelachse 62 bzw. der Lagerung der Spindelachse 62 auszuschalten.The bearing block 61 is inside the hub body 57 floating in the axial direction and is supported relative to the hub body by means of an axially arranged compression spring 64, so that in the direction of the double arrow f5 sufficient axial movement space between the spindle axis 62 and the shaft 56 is possible to when the bearing block 61 is placed on the spindle axis 62 Switch off damage in the area of the spindle axis 62 or the bearing of the spindle axis 62.

Bei der Beschreibung der Konstruktion gemäß Fig. 6 ist auf die Darstellung und Beschreibung von Absaugeinrichtungen verzichtet worden. Es versteht sich, daß einem System gemäß Fig. 6 Absaugeinrichtungen entweder in Form eines zentralen Saugmundstückes 41 oder in Form von seitlich angestellten Saugdüsen zugeordnet werden können, etwa vergleichbar der Saugdüse 59 in Fig. 4.In the description of the construction according to FIG. 6, the representation and description of suction devices has been dispensed with. It goes without saying that suction systems can be assigned to a system according to FIG. 6 either in the form of a central suction mouthpiece 41 or in the form of suction nozzles positioned laterally, roughly comparable to the suction nozzle 59 in FIG. 4.

Die erfindungsgemäße Reinigungseinrichtung kann auch unabhängig von einem Wartungsautomaten verwendet werden, gegebenenfalls mit einem integrierten Antriebsmotor oder mit einem daran ankuppelbaren Antriebsmotor.The cleaning device according to the invention can also be used independently of a maintenance machine, optionally with an integrated drive motor or with a drive motor that can be coupled to it.
