Definitions
- the invention relates to a drive coupling for connecting a drive shaft with an interchangeable cylinder of a printing press.
- Robots are known with which the mostly relatively heavy cylinders can be lifted out of their bearings in the machine frame after the corresponding bearing caps have been opened or removed. If the cylinder is driven by meshing gears, so the meshing is automatically canceled when the cylinder is lifted out of its bearings. Lately, however, have been increasing Drive systems are used in which the cylinders and rollers are one Printing press does not have gear transmission synchronized with the help of a single one Drive motor are driven, but a separate one for each cylinder Drive motor is provided, which is directly on a coaxial with the relevant cylinder connected drive shaft sits.
- Document US-A-4 645 373 discloses a drive clutch with a clamping piece arranged on the drive shaft, the one has a radially opening recess in the end of the cylinder arranged locking part can be guided in a form-fitting manner.
- the object of the invention is to provide a drive clutch, on the one hand a precise direct drive of the cylinder and on the other hand a simple one Exchange of the cylinder permitted.
- a locking part is provided and that in or on the drive shaft a clamping piece is arranged, which has a radially opening recess has, in which the locking part is positively insertable, and that Clamping piece is axially retractable to the cylinder with the help of the locking part pull against one end of the drive shaft.
- the cylinder is closed using the Clamping piece axially clamped against the end of the drive shaft, so that a positive or preferably predominantly non-positive connection is created between the drive shaft and the cylinder.
- the clamping piece With a change of cylinders the clamping piece is extended into a release position, in which exit the locking part radially from the recess of the clamping piece can.
- the cylinder can thus be very easily removed from the drive shaft be uncoupled by using the robot radially in the direction is moved in which the recess of the clamping piece opens.
- the new cylinder can then perform this sequence of movements with its Bolt part inserted into the clamping piece and then by pulling back the Clamping piece can be clamped again against the end of the drive shaft, so that the drive connection is restored.
- the drive clutch according to the invention is particularly for printing presses provided in which the drive coaxially with the cylinder connected drive shaft takes place, the storage of the cylinder in the machine frame but is done directly on the cylinder. Because in this case the bearings are one have a relatively large diameter, the drive coupling, which is natural must have a certain minimum diameter, immediately connect to the bearing of the cylinder or even something in that engage the front end of the cylinder, so that a very small Construction is achieved. Furthermore, it proves advantageous that the Cylinder axially clamped to the drive shaft by the drive coupling becomes. The coupling therefore behaves in the axial direction and in the direction of rotation stiff, so that a precise adjustment of the side register and the longitudinal register is made possible.
- the clutch can do something to be compliant.
- This has the advantage that the axis of rotation of the cylinder is precise is defined by the storage in the machine frame and a minor. eccentricity of the drive shaft due to mounting inaccuracies can be compensated, as in the European patent application 98 121 059 of the applicant.
- the mutually facing ends of the cylinder and the drive shaft preferably form together a friction clutch, which in a particularly preferred Embodiment with a positively engaging coupling, in particular a one-tooth clutch is combined.
- a friction clutch which in a particularly preferred Embodiment with a positively engaging coupling, in particular a one-tooth clutch is combined.
- the Single-tooth clutch to the cylinder in a defined angular position with respect to the drive shaft to keep the setting of the longitudinal register with the help of one arranged on the drive shaft or directly on the motor Angle sensor can take place The transmission of the drive torque. However, this is mainly done through the friction clutch.
- the clamping piece is preferably elastically biased into the clamping position and with the help of an actuating rod running axially through the hollow drive shaft movable into the release position. If the drive shaft is coaxial with is connected to the motor shaft or is formed in one piece with it, the actuating rod can extend through the entire motor and possibly also extend the angle sensor. Then to release the clutch the free end of the operating rod by a pneumatic or hydraulic actuated plunger are applied to the rotation of the drive shaft does not need to participate.
- Figure 1 is one end of a cylinder 10, for example a printing cylinder or an application roller of a printing press, which is shown with the help the drive clutch shown in Figure 3 coupled to a drive shaft 12 shall be.
- An end section of the cylinder shown in section in FIG. 1 10 forms a bearing surface 14 and serves to store the relevant one End of the cylinder 10 in a bearing 16 ( Figure 3), which is not in one shown frame of the printing press is arranged.
- Friction ring 18 arranged at a point on its circumference by a projecting Clutch tooth 20 is interrupted.
- a cylindrical extension projecting coaxially from the end of the cylinder 10 22 carries at the free end a locking part 24 which, as can be seen in FIG is in the shape of a circular disc.
- the drive shaft 12 shown in FIG. 3 carries on its bearing 16 facing End a friction ring 26 which, when the cylinder 10 is coupled, forms a friction clutch together with the friction ring 18 of the cylinder.
- the friction ring 26 is interrupted at one point on its circumference by a notch 28, in which the clutch tooth 20 can engage with a perfect fit, so in the engaged state, the angular position of the cylinder 10 precisely with respect is fixed to the angular position of the drive shaft 12.
- the drive shaft 12 is designed as a hollow shaft and is axially by one continuous operating rod 30 penetrates.
- a clamping piece 32 is attached, which is by means of the actuating rod 30 is axially displaceable in an end section of the drive shaft 12.
- the clamping piece 32 has a U-shaped recess 38 in cross section, which is opens radially in the direction of the notch 28, upwards in FIGS. 3 and 4.
- the Recess 38 is at the free end of the clamping piece through an end wall 40 limited, in which also a U-shaped opening upwards Slot 42 is formed.
- the actuating rod 30 has on its opposite the clamping piece 32 End a plate 44 and is left by a spring 46 in Figure 3 biased so that it has a tendency to the clamping piece 32 in the Retract interior of drive shaft 12.
- the plate 44 is actuated pneumatically or hydraulically Tappet 48 held in position against the force of spring 46 in which protrudes the clamping piece 32 from the open end of the drive shaft 12. If in this state the cylinder 10 using a not shown Robot is inserted into the bearing 16 from above, the locking member 24 enters the recess 38, and the extension 22 lies in the slot 42 of the End wall 40.
- the state is shown in FIG. 5.
- the plunger 48 is then withdrawn so that the spring 46 relaxed and the operating rod 30 and the clamping piece 32 to the left shifts.
- the locking part 24 of the end wall 40 of the clamping piece 40 is detected, and the cylinder 10 is axially in the bearing 10 against the End of the drive shaft 12 pulled so that the friction rings 26 and 28 firmly together brought into frictional contact, as shown in Figure 6.
- the Coupling tooth 20 enters the corresponding notch 28.
- a connection is rigid in the axial direction and in the circumferential direction created between the drive shaft 12 and the cylinder 10.
- the drive shaft 12 of which in the drawing only the respective end sections are shown, can also be the rotor of a drive motor, not shown form so that the drive shaft 12 and also the actuating rod 30 axially pass through the housing of this drive motor.
- a mechanism can also be on the drive shaft 12 attack to adjust the side register, and into the engine can an angle sensor for measuring the angular position of the cylinder 10 for adjustment of the longitudinal register. All adjustment movements for adjustment of the longitudinal and side register are by the invention Transfer the drive clutch to the cylinder 10 without play.
- the bearing 16 is closed with the aid of a bearing cover 50.
- the axis of rotation of the cylinder 10 is then precise through the frame fixed Camp 16 defined. If it is due to dimensional tolerances in the manufacture or mounting the motor housing to a slight eccentricity between the drive shaft 12 and the cylinder 10 comes, this eccentricity be compensated for in that the friction rings 26 and 18 radially somewhat work against each other.
- the clutch tooth 20 also only engages in the circumferential direction free of play, but in the radial direction with play in the corresponding notch the drive shaft. In this way the transmission of radial forces and / or bending moments on the cylinder 10 prevented.
- the bearing cap 50 opened or removed, and the operating rod 30 is by means of Ram 48 moved back to the release position.
- the front wall can 40 of the clamping piece 32 engage on the end face of the cylinder 10 and move the cylinder to an axial position in which the locking member 24th is outside the drive shaft 12 so that the cylinder 10 with the help a robot can lift up out of the bearing 16.

Abstract
Description
Die Erfindung betrifft eine Antriebskupplung zur Verbindung einer Antriebswelle mit einem auswechselbaren Zylinder einer Druckmaschine.The invention relates to a drive coupling for connecting a drive shaft with an interchangeable cylinder of a printing press.
Bei Druckmaschinen ist es häufig erforderlich, zylindrische, drehbantreibbare Elemente wie beispielsweise Druckzylinder, Farbauftragwalzen und dergleichen auszuwechseln. Diese auswechselbaren zylindrischen Elemente werden in dieser Anmeldung kurz als "Zylinder" bezeichnet.In the case of printing presses, it is often necessary to use cylindrical, rotatable drives Elements such as impression cylinders, inking rollers and the like replaced. These are interchangeable cylindrical elements referred to briefly as "cylinder" in this application.
Es sind Roboter bekannt, mit denen die zumeist relativ schweren Zylinder aus ihren Lagern im Maschinengestell herausgehoben werden können, nachdem die entsprechenden Lagerdeckel geöffnet oder entfernt worden sind. Wenn der Antrieb des Zylinders über miteinander kämmende Zahnräder erfolgt, so wird der Zahneingriff automatisch aufgehoben, wenn der Zylinder aus seinen Lagern herausgehoben wird. In letzter Zeit werden jedoch zunehmend Antriebssysteme eingesetzt, bei denen die Zylinder und Walzen einer Druckmaschine nicht über Zahnradgetriebe synchron mit Hilfe eines einzigen Antriebsmotors angetrieben werden, sondern für jeden Zylinder ein gesonderter Antriebsmotor vorgesehen ist, der direkt auf einer koaxial mit dem betreffenden Zylinder verbundenen Antriebswelle sitzt.Robots are known with which the mostly relatively heavy cylinders can be lifted out of their bearings in the machine frame after the corresponding bearing caps have been opened or removed. If the cylinder is driven by meshing gears, so the meshing is automatically canceled when the cylinder is lifted out of its bearings. Lately, however, have been increasing Drive systems are used in which the cylinders and rollers are one Printing press does not have gear transmission synchronized with the help of a single one Drive motor are driven, but a separate one for each cylinder Drive motor is provided, which is directly on a coaxial with the relevant cylinder connected drive shaft sits.
Dokument US-A-4 645 373 offenbart eine Antriebskupplung mit einem auf der Antriebswelle angeordneten Spannstück, das eine sich radial öffnende Ausnehmung aufweist, in die am Ende des Zylinders angeordnetes Riegelteil formschlüssig ein führbar ist.Document US-A-4 645 373 discloses a drive clutch with a clamping piece arranged on the drive shaft, the one has a radially opening recess in the end of the cylinder arranged locking part can be guided in a form-fitting manner.
Aufgabe der Erfindung ist es, eine Antriebskupplung zu schaffen, die einerseits einen präzisen Direktantrieb des Zylinders und andererseits ein einfaches Auswechseln des Zylinders gestattet.The object of the invention is to provide a drive clutch, on the one hand a precise direct drive of the cylinder and on the other hand a simple one Exchange of the cylinder permitted.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an einem Ende des Zylinders ein Riegelteil vorgesehen ist und daß in oder auf der Antriebswelle ein Spannstück angeordnet ist, das eine sich radial öffnende Ausnehmung aufweist, in die das Riegelteil formschlüssig einführbar ist, und daß das Spannstück axial zurückziehbar ist, um den Zylinder mit Hilfe des Riegelteils gegen ein Ende der Antriebswelle zu ziehen.This object is achieved in that at one end of the Cylinder a locking part is provided and that in or on the drive shaft a clamping piece is arranged, which has a radially opening recess has, in which the locking part is positively insertable, and that Clamping piece is axially retractable to the cylinder with the help of the locking part pull against one end of the drive shaft.
Während des Betriebs der Druckmaschine ist der Zylinder mit Hilfe des Spannstücks axial gegen das Ende der Antriebswelle gespannt, so daß eine formschlüssige oder vorzugsweise vorwiegend kraftschlüssige Verbindung zwischen der Antriebswelle und dem Zylinder geschaffen wird. Bei einem Zylindenvechsel wird das Spannstück in eine Freigabeposition ausgefahren, in der das Riegelteil radial aus der Ausnehmung des Spannstücks austreten kann. Der Zylinder kann somit auf sehr einfache Weise von der Antriebswelle abgekuppelt werden, indem er mit Hilfe des Roboters radial in der Richtung bewegt wird, in der sich die Ausnehmung des Spannstücks öffnet. Durch Umkehrung dieses Bewegungsablaufs kann dann der neue Zylinder mit seinem Riegelteil in das Spannstück eingeführt und dann durch Zurückziehen des Spannstücks wieder gegen das Ende der Antriebswelle gespannt werden, so daß die Antriebsverbindung wieder hergestellt wird.During the operation of the printing press, the cylinder is closed using the Clamping piece axially clamped against the end of the drive shaft, so that a positive or preferably predominantly non-positive connection is created between the drive shaft and the cylinder. With a change of cylinders the clamping piece is extended into a release position, in which exit the locking part radially from the recess of the clamping piece can. The cylinder can thus be very easily removed from the drive shaft be uncoupled by using the robot radially in the direction is moved in which the recess of the clamping piece opens. By reversal The new cylinder can then perform this sequence of movements with its Bolt part inserted into the clamping piece and then by pulling back the Clamping piece can be clamped again against the end of the drive shaft, so that the drive connection is restored.
Die erfindungsgemäße Antriebskupplung ist insbesondere für Druckmaschinen vorgesehen, bei denen zwar der Antrieb über die koaxial mit dem Zylinder verbundene Antriebswelle erfolgt, die Lagerung des Zylinders im Maschinengestell jedoch direkt am Zylinder erfolgt. Da in diesem Fall die Lager einen relativ großen Durchmesser haben, kann die Antriebskupplung, die naturgemäß einen gewissen Mindestdurchmesser aufweisen muß, sich unmittelbar an die Lagerstelle des Zylinders anschließen oder sogar etwas in das stirnseitige Ende des Zylinders eingreifen, so daß eine sehr kleinbauende Konstruktion erreicht wird. Weiterhin erweist es sich als vorteilhaft, daß der Zylinder durch die Antriebskupplung axial mit der Antriebswelle verspannt wird. Die Kupplung verhält sich daher in Axialrichtung und in Drehrichtung steif, so daß eine präzise Einstellung des Seitenregisters und des Längsregisters ermöglicht wird. In Radialrichtung kann die Kupplung dagegen etwas nachgiebig sein. Dies hat den Vorteil, daß die Drehachse des Zylinders präzise durch die Lagerung im Maschinengestell definiert wird und eine geringfügige. durch Montageungenauigkeiten bedingte Exzentrizität der Antriebswelle ausgeglichen werden kann, wie auch in der europäischen Patentanmeldung 98 121 059 der Anmelderin beschrieben wird.The drive clutch according to the invention is particularly for printing presses provided in which the drive coaxially with the cylinder connected drive shaft takes place, the storage of the cylinder in the machine frame but is done directly on the cylinder. Because in this case the bearings are one have a relatively large diameter, the drive coupling, which is natural must have a certain minimum diameter, immediately connect to the bearing of the cylinder or even something in that engage the front end of the cylinder, so that a very small Construction is achieved. Furthermore, it proves advantageous that the Cylinder axially clamped to the drive shaft by the drive coupling becomes. The coupling therefore behaves in the axial direction and in the direction of rotation stiff, so that a precise adjustment of the side register and the longitudinal register is made possible. In the radial direction, however, the clutch can do something to be compliant. This has the advantage that the axis of rotation of the cylinder is precise is defined by the storage in the machine frame and a minor. eccentricity of the drive shaft due to mounting inaccuracies can be compensated, as in the European patent application 98 121 059 of the applicant.
Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüche.Advantageous embodiments of the invention result from the subclaims.
Bevorzugt bilden die einander zugewandten Enden des Zylinders und der Antriebswelle miteinander eine Reibungskupplung, die in einer besonders bevorzugten Ausführungsform mit einer formschlüssig eingreifenden Kupplung, insbesondere einer Einzahnkupplung kombiniert ist. In diesem Fall dient die Einzahnkupplung dazu, den Zylinder in einer definierten Winkelpositon in bezug auf die Antriebswelle zu halten, damit die Einstellung des Längsregisters mit Hilfe eines an der Antriebswelle oder direkt am Motor angeordneten Winkelfühlers erfolgen kann Die Übertragung des Antriebsdrehmoments. erfolgt jedoch in der Hauptsache durch die Reibungskupplung.The mutually facing ends of the cylinder and the drive shaft preferably form together a friction clutch, which in a particularly preferred Embodiment with a positively engaging coupling, in particular a one-tooth clutch is combined. In this case, the Single-tooth clutch to the cylinder in a defined angular position with respect to the drive shaft to keep the setting of the longitudinal register with the help of one arranged on the drive shaft or directly on the motor Angle sensor can take place The transmission of the drive torque. However, this is mainly done through the friction clutch.
Bevorzugt ist das Spannstück elastisch in die Spannstellung vorgespannt und mit Hilfe einer axial durch die hohle Antriebswelle verlaufenden Betätigungsstange in die Freigabestellung bewegbar. Wenn die Antriebswelle koaxial mit der Motorwelle verbunden oder in einem Stück mit dieser ausgebildet ist, kann sich die Betätigungsstange durch den gesamten Motor und ggf. auch den Winkelfühler hindurch erstrecken. Zum Lösen der Kupplung kann dann das freie Ende der Betätigungsstange durch einen pneumatisch oder hydraulisch betätigten Stößel beaufschlagt werden, der an der Rotation der Antriebswelle nicht teilzunehmen braucht.The clamping piece is preferably elastically biased into the clamping position and with the help of an actuating rod running axially through the hollow drive shaft movable into the release position. If the drive shaft is coaxial with is connected to the motor shaft or is formed in one piece with it, the actuating rod can extend through the entire motor and possibly also extend the angle sensor. Then to release the clutch the free end of the operating rod by a pneumatic or hydraulic actuated plunger are applied to the rotation of the drive shaft does not need to participate.

In Figur 1 ist ein Ende eines Zylinders 10, beispielsweise eines Druckzylinders
oder einer Auftragwalze einer Druckmaschine dargestellt, das mit Hilfe
der in Figur 3 gezeigten Antriebskupplung an eine Antriebswelle 12 angekuppelt
werden soll. Ein in Figur 1 im Schnitt dargestellter Endabschnitt des Zylinders
10 bildet eine Lagerfläche 14 und dient zur Lagerung des betreffenden
Endes des Zylinders 10 in einem Lager 16 (Figur 3), das in einem nicht
gezeigten Gestell der Druckmaschine angeordnet ist.In Figure 1 is one end of a
Auf der Stirnseite des Zylinders 10 ist angrenzend an die Lagerfläche 16 ein
Reibring 18 angeordnet, der an einer Stelle seines Umfangs durch einen vorspringenden
Kupplungszahn 20 unterbrochen ist.On the face of the
Ein koaxial vom Ende des Zylinders 10 vorspringender zylindrischer Fortsatz
22 trägt am freien Ende ein Riegelteil 24, das, wie in Figur 2 zu erkennen
ist, die Form einer Kreisscheibe hat.A cylindrical extension projecting coaxially from the end of the
Die in Figur 3 gezeigte Antriebswelle 12 trägt an ihrem dem Lager 16 zugewandten
Ende einen Reibring 26, der, wenn der Zylinder 10 angekuppelt ist,
zusammen mit dem Reibring 18 des Zylinders eine Reibungskupplung bildet.
Der Reibring 26 ist an einer Stelle seines Umfangs durch eine Kerbe 28 unterbrochen,
in die der Kupplungszahn 20 paßgenau eingreifen kann, damit
im eingekuppelten Zustand die Winkellage des Zylinders 10 präzise in bezug
auf die Winkellage der Antriebswelle 12 festgelegt ist.The
Die Antriebswelle 12 ist als Hohlwelle ausgebildet und wird axial von einer
durchgehenden Betätigungsstange 30 durchsetzt. Am Ende der Betätigungsstange
30 ist ein Spannstück 32 befestigt, das mit Hilfe der Betätigungsstange
30 axial in einem Endabschnitt der Antriebswelle 12 verschiebbar ist.
Durch einen Bolzen 34, der in eine Längsnut 36 des Spannstücks eingreift,
ist das Spannstück drehfest in der Antriebswelle 12 festgelegt. Das Spannstück
32 weist eine im Querschnitt U-förmige Ausnehmung 38 auf, die sich
radial in Richtung auf die Kerbe 28 öffnet, in Figuren 3 und 4 nach oben. Die
Ausnehmung 38 wird am freien Ende des Spannstücks durch eine Stirnwand
40 begrenzt, in der ein sich gleichfalls nach oben öffnender U-förmiger
Schlitz 42 ausgebildet ist.The
Die Betätigungsstange 30 weist an ihrem dem Spannstück 32 entgegengesetzten
Ende einen Teller 44 auf und wird durch eine Feder 46 nach links in
Figur 3 vorgespannt, so daß sie die Tendenz hat, das Spannstück 32 in das
Innere der Antriebswelle 12 zurückzuziehen. In dem in Figur 3 gezeigten Zustand
wird der Teller 44 durch einen pneumatisch oder hydraulisch betätigten
Stößel 48 entgegen der Kraft der Feder 46 in einer Position gehalten, in
der das Spannstück 32 aus dem offenen Ende der Antriebswelle 12 herausragt.
Wenn in diesem Zustand der Zylinder 10 mit Hilfe eines nicht gezeigten
Roboters von oben in das Lager 16 eingelegt wird, so tritt das Riegelteil 24 in
die Ausnehmung 38 ein, und der Fortsatz 22 legt sich in den Schlitz 42 der
Stirnwand 40. Der Zustand ist in Figur 5 gezeigt.The actuating
Anschließend wird der Stößel 48 zurückgezogen, so daß sich die Feder 46
entspannt und die Betätigungsstange 30 und das Spannstück 32 nach links
verschiebt. Dabei wird das Riegelteil 24 von der Stirnwand 40 des Spannstücks
40 erfaßt, und der Zylinder 10 wird in dem Lager 10 axial gegen das
Ende der Antriebswelle 12 gezogen, so daß die Reibringe 26 und 28 fest miteinander
in Reibberührung gebracht werden, wie in Figur 6 gezeigt ist. Der
Kupplungszahn 20 tritt dabei in die entsprechende Kerbe 28 ein. Auf diese
Weise wird eine in Axialrichtung und in Umfangsrichtung starre Verbindung
zwischen der Antriebswelle 12 und dem Zylinder 10 geschaffen.The
Die Antriebswelle 12, von der in der Zeichnung nur die jeweiligen Endabschnitte
dargestellt sind, kann zugleich den Rotor eines nicht gezeigten Antriebsmotors
bilden, so daß die Antriebswelle 12 und auch die Betätigungsstange
30 axial durch das Gehäuse dieses Antriebsmotors hindurchgehen.
Außerdem kann an der Antriebswelle 12 auch ein nicht gezeigter Mechanismus
zur Einstellung des Seitenregisters angreifen, und in den Motor kann
ein Winkelfühler zur Messung der Winkellage des Zylinders 10 für die Einstellung
des Längsregisters integriert sein. Alle Einstellbewegungen zur Einstellung
des Längs und Seitenregisters werden durch die erfindungsgemäße
Antriebskupplung spielfrei auf den Zylinder 10 übertragen.The
Nachdem der Zylinder 10 in dieser Weise an die Antriebswelle 12 angekuppelt
worden ist, wird das Lager 16 mit Hilfe eines Lagerdeckels 50 geschlossen.
Die Drehachse des Zylinders 10 ist dann präzise durch das gestellfeste
Lager 16 definiert. Falls es infolge von Maßtoleranzen bei der Herstellung
oder Montage des Motorgehäuses zu einer leichten Exzentrizität zwischen
der Antriebswelle 12 und dem Zylinder 10 kommt, so kann diese Exzentrizität
dadurch ausgeglichen werden, daß die Reibringe 26 und 18 radial etwas
gegeneinander arbeiten. Auch der Kupplungszahn 20 greift nur in Umfangsrichtung
spielfrei, in Radialrichtung jedoch mit Spiel in die zugehörige Kerbe
der Antriebswelle ein. Auf diese Weise wird die Übertragung von Radialkräften
und/oder Biegemomenten auf den Zylinder 10 verhindert.After the
Wenn der Zylinder 10 ausgewechselt werden soll, so wird der Lagerdeckel
50 geöffnet oder entfernt, und die Betätigungsstange 30 wird mit Hilfe des
Stößels 48 wieder in die Freigabestellung verschoben. Dabei kann die Stirnwand
40 des Spannstücks 32 an der Stirnfläche des Zylinders 10 angreifen
und den Zylinder in eine axiale Position verschieben, in der das Riegelteil 24
außerhalb der Antriebswelle 12 liegt, so daß sich der Zylinder 10 mit Hilfe
eines Roboters nach oben aus dem Lager 16 ausheben läßt.If the
