[Bezeichnung der Erfindung] Anschlagvorrichtung zum Wechseln eines rotationssymmetrischen Bauteiles in einer Druckmaschine [Description of the Invention] Stop device for changing a rotationally symmetrical component in a printing press
[Beschreibung][Description]
Die Erfindung betrifft eine Anschlagvorrichtung zum Wechsel eines rotationssymmetrischen Bauteiles in einer Druckmaschine nach dem Oberbegriff des Hauptanspruches.The invention relates to a stop device for changing a rotationally symmetrical component in a printing press according to the preamble of the main claim.
[Stand der Technik] Es ist bekannt, dass rotationssymmetrische Bauteile, wie Walzen und/oder Zylinder, in Druckmaschinen manuell oder mittels Hebevorrichtung entnehmbar und in ihren Halterungen austauschbar sind. Hierzu werden die rotationssymmet- rischen Bauteile mit der Hand oder mit Anschlagmitteln, wie zum Beispiel Seilen oder Kranhaken, gegriffen und transportiert. Dies ist relativ aufwendig und die erforderliche Arbeitssicherheit ist oft nicht ausreichend gegeben.PRIOR ART It is known that rotationally symmetrical components, such as rollers and / or cylinders, can be removed manually or by means of a lifting device in printing presses and their holders can be exchanged. For this purpose, the rotationally symmetrical components are gripped and transported by hand or with slings, such as ropes or crane hooks. This is relatively complex and the required work safety is often not sufficient.
Zum Entnehmen eines Zylinders, insbesondere eines Formzy- linders, aus einer Lagerung einer Druckmaschine ist eine entsprechende Vorrichtung aus EP 0 639 452 Bl bekannt. Diese Entnahmevorrichtung weist zwei Greifarme auf, mit denen der Formzylinder aus seiner Lagerung herausschwenk- bar ist. Dabei ist die Ξntnahmevorrichtung neben unter o- der über dem jeweiligen Druckwerk der Druckmaschine angeordnet. Mittels einer Hubvorrichtung wird der Formzylin- der am Druckwerk nach oben gefördert und dort an eine Haltevorrichtung übergeben. Die Hubvorrichtung schwenkt anschließend in eine neue Lageposition, so dass ein neuer Zylinder an die Hubvorrichtung übergeben wird, der von der Hubvorrichtung der Entnahmevorrichtung zugeführt und in seine Lagerungen im Druckwerk wieder einsetzbar ist.A corresponding device is known from EP 0 639 452 B1 for removing a cylinder, in particular a forme cylinder, from a bearing of a printing press. This removal device has two gripping arms with which the forme cylinder can be pivoted out of its storage. The removal device is arranged next to or below the respective printing unit of the printing press. The form cylinder is lifted which is conveyed upwards at the printing unit and transferred there to a holding device. The lifting device then pivots into a new position, so that a new cylinder is transferred to the lifting device, which cylinder is fed from the lifting device to the removal device and can be reinserted in its bearings in the printing unit.

A magazine for anilox rollers is arranged in the coating unit and a lifting device for exchanging anilox rollers is assigned to this magazine.

[Aufgabe der Erfindung]OBJECT OF THE INVENTION
Der Erfindung liegt die Aufgabe zu Grunde eine Anschlag- Vorrichtung der eingangsgenannten Art zu schaffen, die die genannten Nachteile vermeidet, die insbesondere ein sicheres Anschlagen eines rotationssymmetrischen Bauteiles gestattet und eine Verkürzung der Rüstzeiten innerhalb einer Druckmaschine erlaubt.The invention is based on the object of providing a stop device of the type mentioned at the outset which avoids the disadvantages mentioned, which in particular allows a rotationally symmetrical component to be securely struck and allows set-up times to be shortened within a printing press.
Erfindungsgemäß wird die Aufgabe durch die Ausbildungsmerkmale des Hauptanspruches gelöst. Weiterbildungen ergeben sich aus den Unteransprüchen.According to the invention the object is achieved by the training features of the main claim. Further training results from the subclaims.
Ein erster Vorteil der erfindungsgemäßen Anschlagvorrichtung ist darin begründet, das diese eine einfachen Aufbau hat und manuell oder in Verbindung mit einer Handhabevorrichtung, zum Beispiel einem Industrieroboter, zum Wechseln rotationssymmetrischer Bauteile, insbesondere von Zylindern und/oder Walzen, in einer Druckmaschine einsetzbar ist.A first advantage of the stop device according to the invention is based on the fact that it has a simple construction and can be used manually or in connection with a handling device, for example an industrial robot Changing rotationally symmetrical components, in particular cylinders and / or rollers, can be used in a printing press.
Von Vorteil ist weiterhin das zwischen dieser Anschlagvorrichtung und einem rotationssymmetrischen Bauteil, welches ausgewechselt werden soll, ein Formschluß erzeugbar ist, der bei Bedarf lösbar ist. Damit ist ein sicheres Anschlagmittel geschaffen, welches eine mögliche Un- fall- und Verletzungsgefahr bei einem derartigen Bauteilwechsel spürbar reduziert.Another advantage is that a positive connection can be generated between this stop device and a rotationally symmetrical component that is to be replaced, which can be released if necessary. This creates a safe sling that noticeably reduces the risk of accidents and injuries when changing components.
Vorteilhaft ist ebenso, das durch den erzielbaren Formschluß von Anschlagvorrichtung und rotationssymmetri- schem Bauteil eine Lagesicherung des Bauteiles realisierbar ist und die Rüstzeiten beim Wechsel dieser Bauteile verkürzbar sind. So kann das rotationssymmetrische Bauteil in kurzer Zeit aus Lagerungen der Druckmaschine heraus bzw. von außerhalb in die Druckmaschine hinein trans- portiert und in Lagerungen eingesetzt werden. Alternativ ist ebenso ein Austausch von rotationssymmetrischen Bauteilen, vorzugsweise untereinander, in Lagerungen von Druckwerk zu Druckwerk bzw. Lackwerk und umgekehrt kurzfristig realisierbar. Besonders vorteilhaft ist der Einsatz der vorzugsweise automatisiert betreibbaren Anschlagvorrichtung in Verbindung mit einer Handhabevorrichtung. Beispielsweise ist der Wechsel eines rotationssymmetrischen Bauteiles in Verbindung mit einer Handhabevorrichtung, zum Beispiel einem Industrieroboter, Manipulator oder einem Linearsystem, realisierbar, indem an der Handhabevorrichtung zwei synchron bewegliche Anschlagvorrichtungen angeordnet sind, um das rotationssymmetrische Bauteil jeweils end- seitig mittels Formschluß sicher aufzunehmen. Das rotationssymmetrische Bauteil weist dabei an beiden Enden, im Bereich des Zylinderballens bzw. der Zylinder- schulter bzw. des Zylinderzapfens entsprechende Öffnungen, bevorzugt Bohrungen, auf, um mit der Anschlagvorrichtung eine lösbar formschlüssige Verbindung zu realisieren.It is also advantageous that the positional locking of the component can be achieved by the interlocking device and rotationally symmetrical component which can be achieved and the set-up times when these components are changed can be shortened. In this way, the rotationally symmetrical component can be transported out of the printing press bearings or into the printing press from outside and used in bearings in a short time. Alternatively, an exchange of rotationally symmetrical components, preferably with one another, in bearings from printing unit to printing unit or coating unit and vice versa can also be realized at short notice. The use of the preferably automatically operated stop device in connection with a handling device is particularly advantageous. For example, the replacement of a rotationally symmetrical component in connection with a handling device, for example an industrial robot, manipulator or a linear system, can be realized by arranging two synchronously movable stop devices on the handling device in order to securely hold the rotationally symmetrical component at the end by means of a positive fit. The rotationally symmetrical component has corresponding openings, preferably bores, at both ends, in the region of the cylinder barrel or the cylinder shoulder or the cylinder journal, in order to achieve a releasably positive connection with the stop device.

Eine betätigbare Anschlagvorrichtung zum Wechseln eines in einer Lagerung aufgenommenen rotationssymmetrischenAn actuatable stop device for changing a rotationally symmetrical accommodated in a bearing
Bauteiles besteht im Wesentlichen aus einer Kugeltraghulse 1, welche am Umfang wenigstens eine, bevorzugt mehrere, Kugeln 2, verliersicher trägt. Die Kugeln 2 sind um- fangsseitig bevorzugt in einer Ebene angeordnet und ste- hen über den Umfang der Kugeltraghulse 1 hervor oder sind innerhalb des Umfanges zurückziehbar. Die Anschlagvorrichtung weist ferner eine an der Kugeltraghulse 1 angeordnete Betätigungseinrichtung 4 auf und ist mittels ei- nes innerhalb der Kugeltraghulse 1 bewegbaren Bolzens 10 mit jeder Kugel 2 in Funktionsverbindung. Das rotationssymmetrische Bauteil, bevorzugt ein Zylinder bzw. eine Walze, weist an jeder Stirnseite eine zur Rotationsachse des Bauteiles m einer Vertikalen verlaufende Öffnung, z.B. eine Bohrung, auf, um die Anschlagvorrichtung formschlüssig aufzunehmen.The component essentially consists of a ball support sleeve 1, which carries at least one, preferably several, balls 2 on the circumference in a captive manner. The balls 2 are preferably arranged in one plane on the circumference and protrude beyond the circumference of the ball support sleeve 1 or are retractable within the circumference. The stop device also has an actuating device 4 arranged on the ball support sleeve 1 and is nes within the ball support sleeve 1 movable bolt 10 with each ball 2 in functional connection. The rotationally symmetrical component, preferably a cylinder or a roller, has on each end face an opening, for example a bore, running to the axis of rotation of the component in a vertical direction in order to receive the stop device in a form-fitting manner.
Die Kugeltraghulse 1 ist in einer Ausbildung für die ma- nuelle Betätigung mit einem diese Kugeltraghulse 1 oberhalb quer durchdringenden Drehgelenk 3 verbunden, welches eine beidseitige Halterung 5 und einen - parallel zum Drehgelenk 3 - quer dazu angeordneten und die Halterungen 5 verbindenden Griff 6 ausweist (Figur 1) . An der Kugeltraghulse 1 ist weiterhin eine Betätigungseinrichtung 4 angeordnet, welche manuell aktivierbar ist und mit den Kugeln 2 über einen innerhalb der Kugeltraghulse 1 linear bewegbaren Bolzen 10 in Funktionsverbin- dung ist. Der weitere Aufbau wird in den Ausführungen zu Figur 3 näher beschrieben. In Figur 1 und 2 ist gezeigt, dass jede Halterung 5 eine im unteren Bereich angeordnete, gekrümmte Abdrückkurve 7 aufweist. Diese Abdrückkurve 7 ist als Bestandteil der Anschlagvorrichtung beim Wechseln des rotationssymmetrischen Bauteiles auf die Ober- seite eines Lagers aufsetzbar und unterstützt den manuellen Wechselvorgang eines rotationssymmetrischen Bauteiles, bevorzugt eines Druckmaschinenzylinders bzw. einer Druckmaschinenwalze .In a design for manual actuation, the ball support sleeve 1 is connected to a swivel joint 3 which penetrates transversely above this ball support sleeve 1 and which has a holder 5 on both sides and a handle 6 which is arranged transversely thereto and parallel to the swivel joint 3 and connects the holders 5 ( Figure 1). An actuating device 4 is furthermore arranged on the ball support sleeve 1, which can be activated manually and is functionally connected to the balls 2 via a bolt 10 which can be moved linearly within the ball support sleeve 1. The further structure is described in more detail in the explanations for FIG. 3. 1 and 2 show that each holder 5 has a curved push-off curve 7 arranged in the lower region. This push-off curve 7 can be placed on the upper side of a bearing as part of the stop device when changing the rotationally symmetrical component and supports the manual changing process of a rotationally symmetrical component, preferably a printing press cylinder or a printing press roller.
Die Kugeltraghulse 1 ist gemäß Figur 3 in einer Weiterbildung zur Ausbildung gemäß Figur 1 gezeigt, wobei die Betätigungseinrichtung 4 automatisiert, zum Beispiel e- lektrisch, pneumatisch oder hydraulisch, aktivierbar ist. Bevorzugt erfolgt die Aktivierung mittels einer zentralen Steuerung der Druckmaschine. Die Kugeltraghulse 1 weist eine Zuführleitung 8 zum Aktivieren der Betätigungseinrichtung 4 auf, welche im vorliegenden Beispiel pneumatisch beaufschlagbar ist.The ball support sleeve 1 is shown in FIG. 3 in a further development for training in accordance with FIG. 1, the actuating device 4 being able to be activated automatically, for example electrically, pneumatically or hydraulically. The activation is preferably carried out by means of a central one Control of the printing press. The ball support sleeve 1 has a feed line 8 for activating the actuating device 4, which can be acted upon pneumatically in the present example.
Innerhalb der Kugeltraghulse 1 ist ein Bolzen 10 linear bewegbar angeordnet. Im oberen Bereich ist der Bolzen 10 mit der bevorzugt pneumatisch aktivierbaren Betätigungs- einrichtung 4 in Funktionsverbindung. Im unteren Bereich weist der Bolzen 10 nahe der Kugeln 2 eine - vorzugsweise konisch verjüngte - Freidrehung 11 auf .Within the ball support sleeve 1, a bolt 10 is arranged to be linearly movable. In the upper area, the bolt 10 is functionally connected to the preferably pneumatically activatable actuating device 4. In the lower region, the pin 10 has a free rotation 11, preferably a conically tapered one, near the balls 2.
Bevorzugt im mittleren bis oberen Bereich ist ein Kraftsystem 9 angeordnet, welches auf die Betätigungseinrich- tung 4 wirkt. Bevorzugt ist das Kraftsystem 9 eine konzentrisch zum Bolzen 10 angeordneten Druckfeder, welche sich im Inneren der Kugeltraghulse 1 abstützt. An seinem oberen Ende ist der Bolzen 10 mit der Betatigungseinrichtung 4 in Funktionsverbindung. Der Betatigungseinrichtung 4 gegenüberliegend ist ein Oberteil 12 an der Kugeltraghulse 1 ortsfest angeordnet. Betatigungseinrichtung 4 und Oberteil 12 weisen bevorzugt Dichtungen 13 und 12 auf, welche den Innenraum der Kugeltraghulse 1 abdichten. Die Zuführleitung 8 mündet in dem von Betätigungseinrichtung 4 und Oberteil 12 gebildeten Bereich des Innenraumes der Kugeltraghulse 1 ein, so dass die zugeführte Energie, z.B. Druckluft, auf die Betätigungseinrichtung 4 wirkt. Dem Oberteil 12 ist ein Sensor 15 zugeordnet, welcher schaltungstechnisch mit einer zentralen Steuerung der Druckmaschine gekoppelt ist und zumindest die Position der Betätigungseinrichtung 4 (mit Bolzen 10) in einer Endlage erfaßt. Bevorzugt ist dabei die Endlage erfass- bar, in der der Bolzen 10 die Kugeln 2 in der über den Umfang der Kugel raghulse 1 hervorstehenden Position fi- x ertA force system 9, which acts on the actuating device 4, is preferably arranged in the middle to upper region. The force system 9 is preferably a compression spring which is arranged concentrically with the bolt 10 and which is supported in the interior of the ball support sleeve 1. At its upper end, the bolt 10 is functionally connected to the actuating device 4. Opposite the actuating device 4, an upper part 12 is arranged in a stationary manner on the ball support sleeve 1. Actuating device 4 and upper part 12 preferably have seals 13 and 12 which seal the interior of the ball support sleeve 1. The feed line 8 opens into the area of the interior of the ball support sleeve 1 formed by the actuating device 4 and the upper part 12, so that the energy supplied, for example compressed air, acts on the actuating device 4. The upper part 12 is assigned a sensor 15, which is connected in terms of circuitry to a central control of the printing press and detects at least the position of the actuating device 4 (with pin 10) in an end position. The end position in which the bolt 10 fixes the balls 2 in the position protruding over the circumference of the ball raghulse 1 can preferably be detected. x ert
Die Funktionsweise der Anschlagvorrichtung und speziell der Kugeltraghulse 1 ist wie folgt: Ausgangszustand ist, dass die Kugeln 2 über den Umfang der Kugeltraghulse 1 hervorstehen. Dazu wirkt das als Druckfeder ausgebildete Kraftsystem 10 auf die Betätigungseinrichtung 4 und den Bolzen 10, welcher die Kugeln 2 verliersicher über den Umfang der Kugeltraghulse 1 herausdrückt. Die Kugeln 2 liegen somit auf dem zylindrischen Bolzen 10 auf.The functioning of the stop device and especially the ball support sleeve 1 is as follows: The initial state is that the balls 2 protrude beyond the circumference of the ball support sleeve 1. For this purpose, the force system 10 designed as a compression spring acts on the actuating device 4 and the bolt 10, which presses the balls 2 out captively over the circumference of the ball support sleeve 1. The balls 2 are thus on the cylindrical bolt 10.
Soll ein rotationssymmetrisches Bauteil, z.B. eine Druck- maschinenwalze, gewechselt werden, so wird die Betätigungseinrichtung 4 manuell oder automatisiert (pneuma- tisch, hydraulisch bzw. elektrisch) aktiviert. Mittels der aktivierten Betätigungseinrichtung 4 wird der Bolzen 10 linear innerhalb der Kugeltraghulse 1 verschoben, so dass die Freidrehung 11 in Höhe der Kugeln 2 positionier- bar ist. Die Kraftwirkung des Kraftsystems 9 ist in sei- ner Wirkung durch die Betatigungseinrichtung 4 aufgehoben. Die Kugeln 2 sind nun aus dem Umfang zurückziehbar. Wird die Kugeltraghulse 1 in eine Öffnung eines rotationssymmetrischen Bauteiles eingeschoben, so sind die Kugeln 2 durch die Wandung der Öffnung ebenfalls in den Raum der Freidrehung 11 zurückbewegbar. Ist die Endposition erreicht, so wird die Betätigungseinrichtung 4 außer Betrieb gesetzt, das Kraftsystem 9 entspannt sich und der Bolzen 10 bewegt sich in die bereits beschriebene Ausgangsposition zurück. Bei der Bewegung des Bolzen 10 wer- den die Kugeln 2 über die kegelförmig angeschrägte Freidrehung 11 auf den zylindrischen Bolzen 10 gehoben und nach außen gedrückt. Die Kugeln 2 sind zwischen Bolzen 10 und den in der Kugeltraghulse 1 angeordneten Öffnungen selbsthemmend . Bei Einsatz einer Handhabevorrichtung sind an dieser zwei Anschlagvorichtungen angeordnet, deren Betätigungseinrichtungen synchron aktivierbar sind. Die Anschlagvor- richtungen sind derart angeordnet, dass das auszuwechselnde Bauteil endseitig mit seinen Öffnungen sicher mit der Anschlagvorrichtung lösbar verbindbar ist. Dazu greift bei jeder Anschlagvorrichtung die Kugeltraghulse 1 formschlüssig in die Öffnungen des rotationssymmetri- sehen Bauteils ein und transportiert das Bauteil in eine freie Lagerung innerhalb eines Druckwerkes oder Lackwerkes und legt es dort ab.If a rotationally symmetrical component, for example a printing press roller, is to be replaced, the actuating device 4 is activated manually or automatically (pneumatically, hydraulically or electrically). By means of the activated actuating device 4, the bolt 10 is displaced linearly within the ball support sleeve 1, so that the free rotation 11 can be positioned at the height of the balls 2. The force effect of the force system 9 is canceled by the actuating device 4. The balls 2 can now be withdrawn from the circumference. If the ball support sleeve 1 is inserted into an opening of a rotationally symmetrical component, the balls 2 can likewise be moved back into the space of the free rotation 11 through the wall of the opening. When the end position is reached, the actuating device 4 is put out of operation, the force system 9 relaxes and the bolt 10 moves back into the starting position already described. When the bolt 10 moves, the balls 2 are lifted onto the cylindrical bolt 10 by means of the tapered free rotation 11 and pressed outwards. The balls 2 are self-locking between the bolts 10 and the openings arranged in the ball support sleeve 1. When using a handling device, two stop devices are arranged on the latter, the actuating devices of which can be activated synchronously. The stop devices are arranged in such a way that the end of the component to be replaced can be securely detachably connected to the stop device with its openings. For this purpose, the ball support sleeve 1 engages positively in the openings of the rotationally symmetrical component in each stop device and transports the component into free storage within a printing unit or coating unit and deposits it there.
Alternativ ist ein rotationssymmetrisch.es Bauteil endsei- tig auch manuell mit je einer Anschlagvorrichtung über je eine Kugeltraghulse 1 lösbar verbindbar und ist von einem bzw. mehreren Bediener/Bedienern z.B. zu einer Ablage transportierbar und dort ablegbar. Hierzu umgreift der Bediener den Griff 6 und aktiviert die Betätigungsein- richtung 4. Nach Herstellung des Formschlusses zwischen Kugeltraghulse 1 und der entsprechenden Öffnung im rotationssymmetrischen Bauteil ist das Bauteil aus der Lagerung entnehmbar. Der Griff 6 ist hierbei im Drehgelenk 3 umlegbar, so dass unter Ausnutzung der Abdrückkurve 7 das rotationssymmetrische Bauteil leichter aus der Lagerung entnehmbar ist.Alternatively, a rotationally symmetrical component can also be releasably connected at the end manually with one stop device each via a ball support sleeve 1 and can be used by one or more operators, e.g. can be transported to a shelf and stored there. To this end, the operator grips the handle 6 and activates the actuating device 4. After the positive connection between the ball support sleeve 1 and the corresponding opening in the rotationally symmetrical component, the component can be removed from the storage. The handle 6 can in this case be folded over in the swivel joint 3, so that the rotationally symmetrical component can be removed more easily from the storage by using the push-off curve 7.
Nach der Ablage des rotationssymmetrischen Bauteiles kann ein weiteres rotationssymmetrisches Bauteil mittels Anschlagvorrichtung formschlüssig aufgenommen werden. Zur verbesserten Einführung der Kugeltraghulse 1 in eine zugeordnete Öffnung eines rotationssymmetrischen Bauteiles weist diese endseitig eine kegelig oder gekrümmte Einführhilfe 16 auf. [Bezugs zeichenliste]After the rotationally symmetrical component has been deposited, a further rotationally symmetrical component can be positively received by means of a stop device. To improve the insertion of the ball support sleeve 1 into an associated opening of a rotationally symmetrical component, the latter has a conical or curved insertion aid 16 at the end.
