Description

Die Erfindung betrifft eine Behandlungsmaschine für Behälter, z. B. Flaschen, Dosen oder vergleichbare Gefäße, die beispielsweise mit einem Getränk gefüllt, gereinigt, mit einem Etikett versehen, mit einem Verschluss ausgerüstet oder vergleichbaren Behandlungsroutinen unterzogen werden, mit zumindest einer Antriebseinheit mit regelmäßig elektrischem Antriebsmotor sowie Motorgehäuse, ferner mit einer an die Antriebseinheit angeschlossenen Manlpulatianseinheit, und mit einem Antriebsgehäuse, welches die Antrlebseinheit aufnimmt und wenigstens ein Lager für die Manipulationselnheit aufweist, wobei das Motorgehäuse zugleich das Antrlebsgehäuse ist und ein kombiniertes einziges Motor-/Antrlebsgehäuse formt, und wobei das Motor-/Antriebsgehäuse zumindest einen vom Antriebsmotor angetriebenen Befestigungsflansch als Lager zum unmittelbaren Anschluss der Manipulationseinheit aufweist.The invention relates to a treatment machine for containers, for. As bottles, cans or similar containers, for example, filled with a beverage, cleaned, provided with a label, equipped with a closure or comparable treatment routines are subjected, with at least one drive unit with regular electric drive motor and motor housing, further with a to the drive unit connected to a Manlpulatianseinheit, and having a drive housing which accommodates the Antrlebseinheit and at least one bearing for Manipulationselnheit, wherein the motor housing is also the Antrlebsgehäuse and forms a combined single motor / Antrlebsgehäuse, and wherein the motor / drive housing at least one driven by the drive motor Has mounting flange as a bearing for direct connection of the manipulation unit.

Im Rahmen der gattungsbildenden WO 2005/115848 A2 , die eine Behandlungsmaschine gemäß dem Oberbegriff des Anspruchs 1 offenbart, ist eine Abtriebswelle das Antriebsmotors konzentrisch zur Drehachse eines Drehtellers angeordnet. Außerdem ist das obere Ende der Abtriebswelle in eine Aufnahmeeinheit gesteckt. Das wiederum obere Ende der Aufnahmeeinheit weist einen Drehteller auf. Daraus resultiert ein relativ ausladender und wenig kompakter Aufbau. Denn das Motor-/Antriebsgehäuse verfügt über eine ausgeprägte Ausdehnung In axialer Richtung.Within the framework of the generic WO 2005/115848 A2 discloses a treatment machine according to the preamble of claim 1, an output shaft, the drive motor is arranged concentrically to the rotational axis of a turntable. In addition, the upper end of the output shaft is inserted into a receiving unit. The turn upper end of the receiving unit has a turntable. This results in a relatively expansive and not very compact design. Because the motor / drive housing has a pronounced extent in the axial direction.

Vergleichbares gilt für die ebenfalls gattungsgemäße EP 1 596 488 A2 . Auch in diesem Fall ist die erforderliche Abtriebswelle des Antriebsmotores konzentrisch zur Drehachse eines Drehtellers angeordnet Als Folge hiervon stellt sich erneut ein ausladender Aufbau insbesondere In axialer Richtung ein.The same applies to the also generic EP 1 596 488 A2 , Also in this case, the required output shaft of the drive motor is arranged concentrically to the axis of rotation of a turntable. As a result, an expanding structure, in particular, sets in again in the axial direction.

Ganz abgesehen davon befasst sich die EP 1 174 345 A1 mit einer Behandlungsmaschine, bei welcher eine Antriebseinheit in Verbindung mit einem Drehteller zum Einsatz kommt. Solche Drehteller werden nicht einschränkend eingesetzt, um die auf diesen aufstehenden Behälter an verschiedenen Behandlungspositionen vorbeizubewegen, beispielsweise an einem Etikettieraggregat zur Übergabe von Etiketten an den jeweiligen Behälter, an Anbürst- und/oder Andrückstationen usw..Quite apart from that, the EP 1 174 345 A1 with a treatment machine in which a drive unit is used in conjunction with a turntable. Such turntables are not used in a restrictive manner in order to move past the containers resting thereon at various treatment positions, for example on a labeling unit for transferring labels to the respective container, to brushing and / or pressing stations, etc.

Zu diesem Zweck verfügt die bekannte Maschine über eine Steuer- und Regeleinheit sowie einen Stellantrieb, die in einem gemeinsamen Gehäuse untergebracht sind und sich als komplette Baugruppe austauschen lassen. Das hat sich bewährt, weil die Steuer- und Regeleinheit inklusive Stellantrieb funktionssicher in dem fraglichen Antriebsgehäuse untergebracht ist, Folglich Betriebsstörungen vermieden werden. Außerdem kann im Falle einer Funktionsstörung die Antriebseinheit komplett ausgetauscht und folglich unabhängig von der fraglichen Behandlungsmaschine untersucht und gegebenenfalls ersetzt werden.For this purpose, the known machine has a control unit and an actuator, which are housed in a common housing and can be replaced as a complete assembly. This has proven itself because the control unit including actuator reliable in the Inaccurate drive housing is housed, Consequently, malfunctions are avoided. In addition, in the case of a malfunction, the drive unit can be completely replaced and thus examined independently of the treatment machine in question and optionally replaced.

Ausgehend von diesem bewährten Stand der Technik besteht aktuell ein Bedürfnis danach, eine weitere konstruktive Vereinfachung zu erzielen und die Anzahl der verwendeten Bauteile und Baugruppen noch weiter zu verringern. Hier setzt die Erfindung ein.Based on this proven state of the art there is currently a need to achieve a further structural simplification and to further reduce the number of components and assemblies used. This is where the invention starts.

Der Erfindung liegt das technische Problem zugrunde, eine derartige Behendlungamaschine für Behälter so weiterzuentwickeln, dass die Kosten, der konstruktive Aufwand und die Anzahl der erforderlichen Bauteile noch weiter verringert sind.The invention is based on the technical problem of further developing such a handling machine for containers in such a way that the costs, the design complexity and the number of required components are further reduced.

Zur Lösung dieser technischen Problemstellung schlägt die Erfindung eine Behandlungsmaschine für Behälter, z. B. Flaschen, Dosen oder dergleichen gemäß Anspruch 1 vor.To solve this technical problem, the invention proposes a treatment machine for containers, for. As bottles, cans or the like according to claim 1 before.

Im Rahmen der Erfindung fungiert folglich das Motorgehäuse zur Aufnahme des Antriebsmotors zugleich als Antriebsgehäuse, bildet also das einzige kombinierte Motor-/Antriebsgehäuse. Folglich ist das fragliche kombinierte Motor-/Antriebsgehäuse nicht nur zur Aufnahme des Antriebsmotors eingerichtet, sondern weist auch das Lager für die Manipulationseinheit sowie gegebenenfalls weitere Einrichtungen und Aggregate in seinem Inneren auf. Nach vorteilhafter Ausgestaltung wird das vorgenannte Lager von zumindest einem seitens des Antriebsmotors angetriebenen Befestlgungsflansch gebildet, welcher zum unmittelbaren Anschluss der Manipulationseinheit eingerichtet ist. Das kombinierte Motor-/Antriebsgehäuse weist den erwähnten angetriebenen Befestigungsflansch als Lager auf. - Zusätzlich hat es sich bewährt, wenn das kombinierte Motor-/Antriebsgehäuse neben dem Antriebsmotor und dem Lager wenigstens noch einen Sensor aufnimmt, welcher Motoreigenschaften wie Drehzahl, Drehwinkel, Motortemperatur etc. des Antriebsmotors erfasst und bei Bedarf an eine Steuereinheit übermittelt.In the context of the invention, consequently, the motor housing for receiving the drive motor also acts as a drive housing, thus forming the only combined motor / drive housing. Consequently, the combined motor / drive housing in question is not only set up for receiving the drive motor, but also has the bearing for the manipulation unit and optionally further devices and units in its interior. According to an advantageous embodiment, the aforementioned bearing is formed by at least one fastening flange driven by the drive motor, which is set up for the direct connection of the manipulation unit. The combined motor / drive housing has the mentioned driven mounting flange as a bearing. - In addition, it has proven useful if the combined motor / drive housing next to the drive motor and the bearing at least one sensor receives, which detects engine characteristics such as speed, rotation angle, engine temperature, etc. of the drive motor and transmitted to a control unit as needed.

Auf diese Weise wird ein neuartiger Antrieb zur Verfügung gestellt, welcher sämtliche wesentlichen Eigenschaften und Funktionen einer Antriebseinheit in einer Behandlungsmaschine für Behälter übernimmt und zu deren Realisierung auf lediglich ein einziges kombiniertes Motor-/Antriebsgehäuse zurückgreift. D. h., im Rahmen der Erfindung werden gerade nicht ein separates Motorgehäuse und Antriebsgehäuse wie beispielsweise beim Stand der Technik nach der EP 1 174 345 A1 verfolgt, sondern übernimmt das Motorgehäuse zugleich die Funktion des Antriebsgehäuses.In this way, a novel drive is provided, which takes over all the essential properties and functions of a drive unit in a treatment machine for containers and resort to their realization on only a single combined motor / drive housing. D. h., Within the scope of the invention, not just a separate motor housing and drive housing as in the prior art according to the EP 1 174 345 A1 pursued, but takes over the motor housing at the same time the function of the drive housing.

Auf diese Weise wird eine besonders kompakte und kostengünstige Bauweise erreicht. Außerdem lassen sich zahlreiche Bauteile einsparen, wie ein zusätzliches Antriebsgehäuse, ein ergänzendes Lager am Antriebsgehäuse zum Anschluss der Manipulationseinheit, Befestigungsmittel zur Anbringung der Manipulationseinheit an dem betreffenden Lager des Antriebsgehäuses, Dichtungen etc..In this way, a particularly compact and inexpensive construction is achieved. In addition, numerous components can be saved, such as an additional drive housing, a supplementary bearing on the drive housing for connecting the manipulation unit, fastening means for attaching the manipulation unit to the respective bearing of the drive housing, seals etc ..

Gleichzeitig wind der Bauraum verringert und werden geringere Fertigungskosten als bisher beobachtet. Dabel ist die Anwendung des kombinierten einzigen Motor-/Antriebsgehäuses und folglich der kombinierten Motor-/Antriebselnheit insgesamt universell. Tatsächlich lässt sich die beschriebene kombinierte Motor-/Antriebseinheit in Verbindung mit beispielsweise Sternrädern einsetzen, wie sie in der EP 1 174 345 A1 beschrieben werden. Auch die Anwendung bei einer Verschließmaschine entsprechend der DE 103 52 016 B3 ist selbstverständlich denkbar und wird vom Erfindungsgedanken umfasst. Ebenso die Kombination mit einer Reinigungsmaschine nach der DE 197 03 369 A1 .At the same time, wind space is reduced and lower production costs are being observed. Dabel is universally universal using the combined single motor / drive housing, and thus the combined motor / drive unit as a whole. In fact, the described combined motor / drive unit can be used in conjunction with, for example, starwheels, as described in the EP 1 174 345 A1 to be discribed. The application in a capping machine according to the DE 103 52 016 B3 is of course conceivable and is encompassed by the inventive concept. Likewise the combination with a cleaning machine after the DE 197 03 369 A1 ,

Letztendlich kann die kombinierte Motor-/Antriebseinheit mit einzigem Motor-/Antriebsgehäuse Jeden vorzugsweise rotativen Antrieb in einer Behandlungsmaschine für Behälter ersetzen. Auch ein linearer Stelitrleb kann mit der kombinierten Motor-/Antriebseinheit dergestalt kombiniert werden, dass seine hauptsächlich rotative Bewegung In eine lineare Bewegung umgewandelt wird, belspielsweise mit Hilfe eines Zahnstangenantriebes oder vergleichbaren Getriebeanordnungen.Finally, the combined motor / drive unit with single motor / drive housing can replace any preferably rotary drive in a container handling machine. A linear actuator control can also be combined with the combined motor / drive unit in such a way that its mainly rotational movement is converted into a linear movement, for example with the aid of a rack drive or comparable gear arrangements.

Dabei hat es sich ergänzend als besonders günstig erwiesen, dass das kombinierte einzige Motor-/Antriebsgehäuse der Motor-/Antriebseinheit mit zumindest einer Hohlbohrung ausgerüstet ist. Denn diese Hohlbohrung kann zur direkten Kopplung mit einer Antriebswelle der Manipulationseinheit genutzt werden. D. h., die fragliche Antriebswelle der Manipulationseinheit benötigt keine zusätzliche Lagerung (mehr), da diese durch die Lagerung des angetriebenen Befestigungsflansches im Motor-/Antriebsgehäuse zur Verfügung gestellt wird. Der angetriebene Befestigungsflansch eignet sich zum unmittelbaren Anschluss der Manipulationseinheit, beispielsweise über die in die Hohlbohrung eingesteckte und mit dem Befestigungsflansch drehfest verbundene Antriebswelle.It has additionally proven to be particularly favorable that the combined single motor / drive housing of the motor / drive unit equipped with at least one hollow bore. Because this hollow bore can be used for direct coupling with a drive shaft of the manipulation unit. In other words, the drive shaft of the manipulation unit in question requires no additional support (more), since this is provided by the mounting of the driven mounting flange in the motor / drive housing. The driven mounting flange is suitable for direct connection of the manipulation unit, for example via the inserted into the hollow bore and rotatably connected to the mounting flange drive shaft.

Ergänzende Optionen bestehen darin, dass die kombinierte Motor-/Antriebseinheit mit einer zusätzlichen Kühlung, z. B. Wasserkühlung, ausgerüstet wird. Diese Kühlung wird primär für den Antriebsmotor bei Bedarf genutzt. Zusätzlich kann der Antriebsmotor mit einer Bremse, z. B. pneumatischen Bremse, ausgerüstet werden. Sowohl die Kühlung als auch die Bremse werden selbstverständlich - wiederum - in dem kombinierten einzigen Motor-/Antriebsgehäuse aufgenommen.Additional options are that the combined motor / drive unit with additional cooling, z. B. water cooling, is equipped. This cooling is used primarily for the drive motor when needed. In addition, the drive motor with a brake, z. B. pneumatic brake, be equipped. Of course, both the cooling and the brake are - again - included in the combined single motor / drive housing.

Als elektrischer Antriebsmotor hat sich ein sogenannter Reluktanzmotor als günstig erwiesen. Bei einem solchen Reluktanzmotor handelt es sich um eine spezielle Bauform eines Elektromotors, bei welchem ein zugehöriger Rotor aus insbesondere weichmagnetischem Material (z. B. Eisen) besteht bzw. solches Material aufweist und der korrespondierende Stator die erforderlichen Magnetspulen enthält. Der Rotor ist weder mit Permanentmagneten bestückt noch wird er bestromt. Er besitzt vielmehr ausgeprägte Pole aus dem weichmagnetischem Material. Dementsprechend ist die Funktionsweise ähnlich wie bei einem elektrischen Linearantrieb und funktioniert praktisch reibungslos. In vorteilhafter Ausgestaltung handelt es sich bei dem Antriebsmotor um einen rotativen nutenlosen Synchronmotor, bei welchem die Magnetspulen des Stators auf einem flachen Eisenring befestigt sind. Demgegenüber ist der mit einem Magnetring aus Eisen ausgerüstete Rotor unter Berücksichtigung eines Luftspaltes im Vergleich zum Stator angeordnet.As an electric drive motor, a so-called reluctance motor has proven to be favorable. Such a reluctance motor is a special design of an electric motor in which an associated rotor consists in particular of a soft magnetic material (eg iron) or such Has material and the corresponding stator contains the required magnetic coils. The rotor is neither equipped with permanent magnets nor energized. He has rather pronounced poles of the soft magnetic material. Accordingly, the operation is similar to an electric linear drive and works practically smoothly. In an advantageous embodiment, the drive motor is a rotary, slotless synchronous motor, in which the magnetic coils of the stator are fastened on a flat iron ring. In contrast, the equipped with a magnetic ring made of iron rotor is arranged taking into account an air gap compared to the stator.

Auf diese Weise verfügt der Antriebsmotor über eine hohe Dynamik und eine große Flexibilität hinsichtlich seiner Konstruktion und kann einen weiten Drehmomentbereich bis zu mehreren 1000 Nm abdecken. Außerdem gewährleistet diese Bauform, dass die kombinierte Motor-/Antriebseinheit bzw. das zugehörige einzige Motor-/Antriebsgehäuse überhaupt mit der bereits angesprochenen Hohlbohrung zur Kopplung mit der Antriebswelle der Manipulationseinheit ausgerüstet werden kann. Denn sowohl der Stator als auch der Rotor sind jeweils vorteilhaft hohlzylindrisch ausgebildet und definieren auf diese Weise die bereits angesprochene Hohlbohrung in ihrem Innern, die jedoch nicht zwingend ist.In this way, the drive motor has a high dynamic and a great flexibility in its construction and can cover a wide torque range up to several 1000 Nm. In addition, this design ensures that the combined motor / drive unit or the associated single motor / drive housing can be equipped at all with the already mentioned hollow bore for coupling to the drive shaft of the manipulation unit. Because both the stator and the rotor are each advantageously designed as a hollow cylinder and define in this way the already mentioned hollow bore in its interior, which is not mandatory.

Gegenstand der Erfindung ist auch die Verwendung eines elektrischen Antriebsmotors mit Motorgehäuse als Antriebseinheit nach Anspruch 6.The invention also provides the use of an electric drive motor with motor housing as the drive unit according to claim 6.

Bei der Manipulationseinheit 7 handelt es sich im Rahmen der Etikettiermaschine nach Fig. 2 um ein Sternrad, wohingegen die Manipulationseinheit 7 bei der Variante nach Fig. 3 als Schraubwelle ausgeführt ist bzw. eine solche aufweist, welche behälterseitig einen Schraubkopf 7a aufweist, der seinerseits den Verschluss 3 auf der Flasche 1 anbringt.These all treatments or the individual treatment machines are characterized by the fact that a drive unit 4 with drive motor 5 and motor housing 6 is realized. To the drive unit 4, a manipulation unit 7 is connected. The manipulation unit 7 is within the scope of the labeling machine Fig. 2 around a star wheel, whereas the manipulation unit 7 in the variant according to Fig. 3 is designed as a screw shaft or has such a container side which has a screw head 7a, which in turn attaches the closure 3 on the bottle 1.

Die Antriebseinheit 4 wird in einem Antriebsgehäuse 6 aufgenommen, weiches erfindungsgemäß zugleich das Motorgehäuse 6 ist. Zusätzlich weist die Antriebseinheit 4 wenigstens ein Lager 8 für die Manipulationseinheit 7 bzw. zu deren Anschluss auf.The drive unit 4 is accommodated in a drive housing 6, which according to the invention is at the same time the motor housing 6. In addition, the drive unit 4 has at least one bearing 8 for the manipulation unit 7 or for its connection.

Im Rahmen des Ausführungsbeispiels handelt es sich bei dem Lager 8 um einen mit Hilfe des Antriebsmotors 5 rotativ angetriebenen Befestigungsflansch 8. Der Befestigungsflansch 8 ist zum unmittelbaren Anschluss der Manipulationseinheit 7 geeignet. Im Übrigen schließt der Befestigungsflansch 8 das zylindrische kombinierte Motor-/Antriebsgehäuse 6 kopfseitig in der Art eines Deckels ab. Tatsächlich ist die Manipulationseinheit 7 unmittelbar mit dem Befestigungsflansch 8 verbunden. Während das Motor-/Antriebsgehäuse 6 ortsfest ausgelegt und mit Hilfe eines Befestigungsankers 12 an einer nicht näher spezifizierten Basis festgelegt ist, rotiert demgegenüber der Befestigungsflansch 8, und zwar angetrieben mit Hilfe des Antriebsmotors 5.In the context of the exemplary embodiment, the bearing 8 is a fastening flange 8 which is driven rotatively by means of the drive motor 5. The fastening flange 8 is suitable for the direct connection of the manipulation unit 7. Incidentally, the fastening flange 8 closes off the cylindrical combined motor / drive housing 6 at the head in the manner of a cover. In fact, the manipulation unit 7 is directly connected to the mounting flange 8. While the motor / drive housing 6 is designed stationary and fixed by means of a fastening anchor 12 on an unspecified basis, in contrast, the mounting flange 8, driven by means of the drive motor 5 rotates.

Wie bereits ausgeführt, übernimmt das Motorgehäuse 6 zugleich die Funktion des Antriebsgehäuses 6, d. h. Motorgehäuse 6 und Antriebsgehäuse 6 sind deckungsgleich und formen das kombinierte einzige Motor-/Antriebsgehäuse 6. Folgerichtig handelt es sich vorliegend um eine kombinierte Motor-/Antriebseinheit 4, 5 mit einzigem kombinierten Motor-/Antriebsgehäuse 6.As already stated, the motor housing 6 at the same time assumes the function of the drive housing 6, d. H. Motor housing 6 and drive housing 6 are congruent and form the combined single motor / drive housing 6. Consequently, this is a combined motor / drive unit 4, 5 with a single combined motor / drive housing. 6

Im Innern des einzigen kombinierten Motor-/Antriebsgehäuse 6 findet sich neben dem Antriebsmotor 5 zusätzlich noch wenigstens ein Sensor 9. Mit Hilfe dieses lediglich in Fig. 1 angedeuteten Sensors 9 lässt sich die Drehzahl des Antriebsmotors 5 erfassen. Ergänzend kann der Sensor 9 auch den Drehwinkel des Antriebsmotors 5 bestimmen sowie dessen Temperatur. Zugehörige Daten des Sensors 9 werden an eine extern angeschlossene und lediglich in Fig. 1 angedeutete Steuereinheit 10 übermittelt. Die Steuereinheit 10 dient üblicherweise zur Steuerung der gesamten Behandlungsmaschine entsprechend den Fig. 2 und 3. Das ist im Detail jedoch nicht dargestellt.In the interior of the single combined motor / drive housing 6 is in addition to the drive motor 5 additionally at least one sensor 9. With the help of this only in Fig. 1 indicated sensor 9 can detect the speed of the drive motor 5. In addition, the sensor 9 can also determine the angle of rotation of the drive motor 5 and its temperature. Associated data of the sensor 9 are connected to an externally connected and only in Fig. 1 indicated control unit 10 transmitted. The control unit 10 is usually used to control the entire treatment machine according to the Fig. 2 and 3 , This is not shown in detail.

Anhand der Schnittdarstellung in Fig. 1 erkennt man, dass die kombinierte Motor-/Antriebseinheit 4, 5 und folgerichtig das einzige Motor-/Antriebsgehäuse 6 zumindest eine Hohlbohrung 11 aufweist. In dieser Hohlbohrung 11 kann eine Antriebswelle der Manipulationseinheit 7 aufgenommen werden. Das wird unmittelbar beim Betrachten der Fig. 2 und 3 deutlich, wo die Antriebswelle der Manipulationseinheit 7 jeweils (drehfest) in die Hohlbohrung 11 der kombinierten Motor-/Antriebseinheit 4, 5 eingesteckt ist. Denn die Hohlbohrung 11 findet sich im topfförmig gestalteten Befestigungsflansch 8, welcher durch den Antriebsmotor 5 rotativ angetrieben wird. Folglich wird auch die drehfest in der Hohlbohrung 11 des Befestigungsflansches 8 verkeilte Antriebswelle für das Sternrad nach Fig. 2 bzw. die Schraubwelle entsprechend der Fig. 3 bei Beaufschlagung des Antriebsmotors 5 in Rotationen versetzt.Based on the sectional view in Fig. 1 it can be seen that the combined motor / drive unit 4, 5 and, consequently, the only motor / drive housing 6 has at least one hollow bore 11. In this hollow bore 11, a drive shaft of the manipulation unit 7 can be added. This becomes immediate when looking at the Fig. 2 and 3 clearly where the drive shaft of the manipulation unit 7 each (non-rotatably) in the hollow bore 11 of the combined motor / drive unit 4, 5 is inserted. Because the hollow bore 11 is found in cup-shaped mounting flange 8, which is driven by the drive motor 5 rotatably. Consequently, the drive shaft rotatably in the hollow bore 11 of the mounting flange 8 wedged for the star wheel after Fig. 2 or the screw shaft according to the Fig. 3 when actuated by the drive motor 5 is rotated.

Der Antriebsmotor 5 bzw. die kombinierte Motor-/Antriebseinheit 4, 5 mag mit einer zusätzlichen und nicht ausdrücklich dargestellten Kühlung, z. B. Wasserkühlung, ausgerüstet werden. Ebenso liegt es im Rahmen der Erfindung, für den Antriebsmotor 5 eine ergänzende Bremse vorzusehen. Sowohl die Kühlung als auch die Bremse werden in dem einzigen kombinierten Motor-/Antriebsgehäuse 6 aufgenommen.The drive motor 5 or the combined motor / drive unit 4, 5 may with an additional and not explicitly shown cooling, z. B. water cooling, be equipped. It is also within the scope of the invention to provide a supplementary brake for the drive motor 5. Both the cooling and the brake are accommodated in the single combined motor / drive housing 6.

Als Antriebsmotor 5 kommt vorliegend ein Reluktanzmotor zum Einsatz, also ein Elektromotor, dessen Rotor 5a aus weichmagnetischem Material hergestellt ist bzw. solches Material in Gestalt von daran angebrachten Eisenmagneten im Beispielfall aufweist. Mit dem Rotor 5a ist der rotativ angetriebene Befestigungsflansch 8 und folglich auch die bereits angesprochene Antriebswelle für das Sternrad (Fig. 2) bzw. die Schraubwelle (Fig. 3) verbunden.In the present case, the drive motor 5 used is a reluctance motor, that is to say an electric motor whose rotor 5a is made of soft magnetic material or has such material in the form of iron magnets attached thereto in the example. With the rotor 5a of the rotatably driven mounting flange 8 and consequently also the already mentioned drive shaft for the star wheel ( Fig. 2 ) or the screw shaft ( Fig. 3 ) connected.

Zu dem Rotor 5a des Antriebsmotors 5 korrespondiert ein Stator 5b, welcher lediglich angedeutete Magnetspulen enthält. Die Funktionsweise des Reluktanzmotors ist vergleichbar mit derjenigen eines elektrischen Linearmotors. Tatsächlich wird in den Magnetspulen des Stators 5b ein Drehfeld erzeugt, welchem der Rotor 5a mit seinen Eisenmagneten folgt und sich synchron mit dem Drehfeld dreht. Als Folge hiervon wird auch der an den Rotor 5a angeschlossene Befestigungsflansch 8 in Drehungen versetzt, welchen die angeschlossene Manipulationseinheit 7 folgt.To the rotor 5a of the drive motor 5 corresponds to a stator 5b, which contains only indicated magnetic coils. The operation of the reluctance motor is comparable to that of a linear electric motor. In fact, in the magnetic coils of the stator 5b, a rotating field is generated, which the rotor 5a follows with its iron magnets and rotates synchronously with the rotating field. As a result, the attachment flange 8 connected to the rotor 5a is also set in rotation, which is followed by the connected manipulation unit 7.
