Abstract

The suction device includes a suction head (1) made of elastomeric material, for providing a sheet bearing surface (2). Suction cavities (3) on the suction head attract the back edge of the sheet onto the sheet bearing surface. The suction head is pivotable via a joint (4) so that it can tilt about a tilt axis parallel to the axis of rotation of the turning drum. The tilting range (S) is limited by a stop (5) which cooperates with the suction head.

Description

Die Erfindung richtet sich auf einen Abnahmesauger für den Einsatz in einer, eine Wendetrommel umfassenden Bogenwendeeinrichtung zur Durchführung einer Hinterkantenwendung.The invention is directed to a take-off vacuum cleaner for use in a, a turning drum comprehensive sheet turning device for performing a trailing edge turn.

Aus DE 30 09 783 A1 ist ein Sauger für eine Bogenwendeeinrichtung bekannt. Dieser Sauger dient dazu den Abgriff einer Bogenhinterkante von einem bogenführenden Zylinder einzuleiten und den Bogenhinterkantenbereich an ein Greifersystem zu übergeben. Der Sauger ist aus einem gummielastischen Material gefertigt und umfasst einen Bogenauflageabschnitt mit darin vertieft verlaufenden Saugkanälen.Out DE 30 09 783 A1 a sucker for a sheet turning device is known. This sucker is used to initiate the tapping of a sheet trailing edge of a sheet-guiding cylinder and transfer the sheet trailing edge region to a gripper system. The nipple is made of a rubber-elastic material and comprises a sheet support section with recessed suction channels therein.

Aus DE 36 43 915 A1 ist ebenfalls ein Sauger für eine Wendetrommel einer Druckmaschine bekannt. Der Sauger ist als Springsauger ausgebildet und umfasst einen Saugerkopf der eine dem anzusaugenden Bogenabschnitt zugewandte Bogenanlagefläche bildet. Der Sauger ist derart ausgebildet, dass unmittelbar nach Abdeckung der Bogenanlagefläche durch den Bogenabschnitt (Bogenhinterkantenrandbereich) der Sauger eingezogen wird.Out DE 36 43 915 A1 is also a sucker for a beater of a printing press known. The sucker is designed as a spring aspirator and comprises a suction head which forms a bow contact surface facing the sheet section to be sucked. The sucker is designed such that immediately after covering the sheet contact surface by the arc section (Bogenhinterkantenrandbereich) of the sucker is retracted.

Aus DE 40 12 497 A1 ist eine Saugersteuerung zur Ansteuerung der Sauger einer Bogenübergabetrommel bekannt, bei welcher die Sauger über eine Getriebeeinrichtung zwangsgesteuert bewegt werden, zur Überführung eines durch die Sauger ergriffenen Bogenhinterkantenbereiches in einen Greiferbereich.Out DE 40 12 497 A1 a sucker control for controlling the suction of a sheet transfer drum is known, in which the suckers are forcibly moved via a transmission means for transferring a trailing edge of the sheet trapped by the suction in a gripper region.

Insbesondere bei der Führung der Sauger entlang einer zwangsweise getrieblich festgelegten Bewegungsbahn besteht das Problem, dass sich für das Abgreifen des Bogenhinterkantenbereiches in Abhängigkeit von den mechanischen Eigenschaften des Bedruckstoffes, sowie der Dicke des Bedruckstoffes unterschiedliche Greifbedingungen und damit Schwankungen bei der Übergabeposition der Bogenhinterkante, der Griffsicherheit und Griffgenauigkeit ergeben.In particular, in the leadership of the suction along a forcibly fixed movement path, the problem is that for the tapping of the sheet trailing edge region in dependence on the mechanical properties of the printing material, and the thickness of the substrate different gripping conditions and thus fluctuations in the transfer position of the sheet trailing edge, the grip and give grip accuracy.

Aus US 4,343,241 ist eine Bogenwendeeinrichtung gemäß des Oberbegriffs des Anspruchs 1 bekannt.Out US 4,343,241 a sheet turning device according to the preamble of claim 1 is known.

Der Erfindung liegt die Aufgabe zugrunde, einen Sauger für eine Wendeeinrichtung zu schaffen, der sich durch vorteilhafte Greifeigenschaften und eine große Kompatibilität zu verschiedenen Bedruckstoffen, insbesondere zu unterschiedlich dicken Bedruckstoffen auszeichnet.The invention has for its object to provide a vacuum cleaner for a turning device, which is characterized by advantageous gripping properties and a high compatibility with different substrates, in particular to different thicknesses of printing materials.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Bogenwendeeinrichtung gemäß Anspruch 1.This object is achieved by a sheet turning device according to claim 1.

Auf Grundlage der erfindungsgemäßen Gestaltung des Saugers wird es möglich, ein Saugersystem zu schaffen, das sich selbsttätig an die jeweilige Bogenstärke anpasst und sich damit bei verschiedenen Bedruckstoffdicken durch eine weitgehend gleichbleibend hohe Übergabegenauigkeit auszeichnet.On the basis of the design of the nipple according to the invention, it is possible to provide a nipple system that automatically adapts to the respective sheet thickness and is thus characterized at different substrate thicknesses by a largely consistently high transfer accuracy.

Gemäß einer besonders bevorzugten Ausführungsform der Erfindung ist die Gelenkeinrichtung als Scharniergelenk ausgebildet. Dieses Scharniergelenk kann insbesondere als Film- oder Folienscharnier realisiert sein. Die Scharniereinrichtung kann weiterhin so ausgebildet sein, dass durch diese der Saugerkopf in eine vorgegebene Richtung, insbesondere eine zum Aufgreifen dünner Bedruckstoffe geeignete Ausrichtung vorgespannt ist.According to a particularly preferred embodiment of the invention, the hinge device is designed as a hinge joint. This hinge joint can be realized in particular as a film or film hinge. The hinge device can furthermore be designed so that the suction head is biased by it in a predetermined direction, in particular a suitable for picking thin substrates suitable orientation.

Die Gelenkeinrichtung ist vorzugsweise weiterhin derart angeordnet und ausgebildet, dass die durch diese definierte Kippachse sich nahe dem in Bogenlaufrichtung gesehen, stromabwärts liegenden Endbereich des Saugerkopfes befindet. Durch diese Anordnung der Kippachse wird es insbesondere möglich, dickere und infolge ihrer Biegesteifigkeit im Hinterkantenbereich von dem bogenführenden Zylinder abragende Abschnitte des Bogens sicher aufzugreifen.The hinge device is preferably further arranged and designed such that the tilting axis defined by the latter is located close to the downstream end region of the suction head, viewed in the sheet running direction. This arrangement of the tilting axis makes it possible in particular to reliably pick up thicker sections of the arch projecting from the sheet-guiding cylinder as a result of their flexural rigidity in the trailing edge region.

Es ist möglich, den Sauger derart auszubilden, dass die Kippbewegung des Saugerkopfes zur Anschlagfläche hin unterstützt wird, sobald der zu ergreifende Bogenabschnitt auf der Bogenauflagefläche aufsitzt und diese hierbei abdeckt. Diese Unterstützung kann erreicht werden, indem infolge des nach Abdeckung der Bogenauflagefläche durch den entsprechenden Bogenabschnitt im Inneren des Saugkopfes herrschenden Unterdruckes eine Zylinder- oder Balgstruktur aktiv wird. Der Kippbereich des Saugerkopfes liegt vorzugsweise im Bereich von ca. 3 bis 15°. Auch die Endstellung des Saugerkopfes in ausgeklapptem Zustand wird vorzugsweise durch eine Anschlagstruktur festgelegt.It is possible to design the nipple such that the tilting movement of the nipple head is supported towards the stop surface as soon as the sheet section to be taken up rests on the sheet support surface and covers it. This support can be achieved by activating a cylinder or bellows structure as a result of the negative pressure prevailing in the interior of the suction head after covering the sheet support surface by the corresponding arc section. The tilting region of the suction head is preferably in the range of about 3 to 15 °. The end position of the cleaner head in the unfolded state is preferably determined by a stop structure.

Die durch den Saugkopf bereitgestellte Saugfläche ist über die erfindungsgemäß vorgesehene Scharnier- oder Gelenkeinrichtung kippbewegbar an einem Saugfingerkorpus angelenkt. Dieser Saugfingerkorpus kann Teil einer Hubsaugereinrichtung bilden und durch Anlegen von Unterdruck, insbesondere nach Abdeckung der Saugfläche zu einem Anschlag hin zurückgezogen werden, wobei der Anschlag die genaue Lage der zu übergebenden Bogenkante festlegt. Die Rückstellung des Saugfingers kann durch ein federndes Element (Stahlfeder, Elastomerstruktur, ETC) erfolgen. Durch die gelenkige Lagerung des Saugerkopfes wird es möglich, unterschiedlich dicke und unterschiedlich biegesteife Bedruckstoffe zuverlässig zu verarbeiten. Die Klappbewegung des Saugerkopfes ist der eigentlichen Saugerbewegung überlagert und vereinfacht insoweit deren Steuerung.The suction surface provided by the suction head is hinged on the inventively provided hinge or hinge means tiltable on a suction finger body. This Saugfingerkorpus can form part of Hubsaugereinrichtung and be withdrawn by applying negative pressure, in particular after covering the suction surface to a stop out, the stop determines the exact location of the sheet edge to be transferred. The return of the suction finger can be done by a resilient element (steel spring, elastomer structure, ETC). Due to the articulated mounting of the suction head, it is possible to reliably process different thicknesses and different bending resistant substrates. The folding movement of the cleaner head is superimposed on the actual suction movement and simplifies the extent of their control.

Der den Saugerkopf tragende Saugfingerabschnitt des Saugers kann ähnlich wie aus DE 40 12 498 A1 bekannt, durch eine entsprechende Getriebeeinrichtung betätigt werden. Durch die erfindungsgemäß vorgesehene kippbewegbare Lagerung des Saugerkopfes wird es möglich, unterschiedlichen Materialstärken des Bedruckstoffes hinreichend Rechnung zu tragen. Durch die erfindungsgemäße Lagerung des Saugerkopfes ergeben sich insbesondere die nachfolgenden Vorteile:

  • Durch die bewegbare Anordnung des Saugerkopfes kann dieser so positioniert werden, dass dieser die Führung der Bogenhinterkante entlang einer idealen Bogenführungsbahn unterstützt, so dass die Saugerbewegung entsprechend vereinfacht werden kann.
  • Die Einstellung des Saugers auf die Dicke des jeweils zu verarbeitenden Bedruckstoffes erfolgt automatisch und gestattet gegebenenfalls auch die Verarbeitung von Materialien, die bei herkömmlichen Systemen zur Überlastung führen.
  • Da das Federelement direkt an der Wirkstelle sitzt, kann es schwächer ausgelegt werden, was dazu führt, dass diese Komponenten geringer belastet werden.
The sucking head carrying suction finger portion of the teat may be similar to DE 40 12 498 A1 known to be actuated by a corresponding transmission device. By inventively provided tiltable storage the suction head, it is possible to sufficiently take into account different material thicknesses of the printing material. The inventive storage of the cleaner head results in particular the following advantages:
  • By the movable arrangement of the suction head this can be positioned so that it supports the guidance of the sheet trailing edge along an ideal sheet guide path, so that the suction movement can be simplified accordingly.
  • The adjustment of the nipple to the thickness of each substrate to be processed is done automatically and possibly also allows the processing of materials that lead to overload in conventional systems.
  • Since the spring element sits directly at the point of action, it can be designed to be weaker, which means that these components are loaded less.

Further details and features of the invention will become apparent from the following description taken in conjunction with the drawings. It shows:
FIG. 1
a perspective view of a teat for a beater according to the invention,
FIG. 2
a further perspective view of the teat according to the invention for explaining an integrated in this bellows device,

Der in Figur 1 dargestellte Sauger für eine Wendetrommel umfasst einen Saugerkopf 1, der vorzugsweise aus einem elastomeren Material gefertigt ist und als solcher der Bereitstellung einer Bogenauflagefläche 2 dient.The in FIG. 1 shown sucker for a beater comprises a suction head 1, which is preferably made of an elastomeric material and as such serves to provide a sheet support surface 2.

In dem Saugerkopf 1 sind mehrere Saugkavernen 3 ausgebildet, die mit einem unterhalb der Bogenauflagefläche 2 verlaufenden Saugkanal kommunizieren. An diesen Saugkanal ist ein unter dem Umgebungsdruck liegender Druck anlegbar zum Ansaugen eines Hinterkantenbereiches eines Bogens an die Bogenauflagefläche 2 im Rahmen der Einleitung einer Hinterkantenwendung.In the suction head 1 a plurality Saugkavernen 3 are formed, which communicate with a running below the sheet support surface 2 suction channel. At this suction channel, a pressure below the ambient pressure can be applied for sucking a trailing edge region of a sheet to the sheet support surface 2 in the context of the initiation of a trailing edge.

Der Saugerkopf 1 ist über eine Gelenkeinrichtung 4 derart schwenkbewegbar gelagert, dass dieser um eine zur Rotationsachse einer hier nicht näher dargestellten Wendetrommel parallele Kippachse X kippbar ist. Der Kippbereich S ist durch eine mit dem Saugerkopf 1 zusammenwirkende Anschlageinrichtung 5 begrenzt.The nipple head 1 is pivotably mounted via a hinge device 4 in such a way that it can be tilted about a tilting axis X which is parallel to the axis of rotation of a turning drum not shown here. The tilting region S is delimited by a stop device 5 cooperating with the suction head 1.

Die Gelenkeinrichtung 4 ist als Scharniergelenk ausgebildet. Die durch die Gelenkeinrichtung 4 definierte Kippachse X erstreckt sich nahe dem in Bogenlaufrichtung BLR gesehen stromabwärts liegenden Endbereich des Saugerkopfes 1. Die Gelenkeinrichtung 4 ist bei diesem Ausführungsbeispiel als Film- oder Folienscharnier ausgebildet. Über dieses Film- oder Folienscharnier ist der Saugerkopf 1 über eine hier lediglich beispielhaft als Schraube 6 dargestellte Befestigungsstruktur mit einer Saugerfingerbasis 7 gekoppelt. Bei diesem Ausführungsbeispiel wird die Anschlageinrichtung 5 unmittelbar durch diese Saugerfingerbasis 7 im Zusammenspiel mit einer in den Saugerkopf 1 integrierten oder an diesen angekoppelten Struktur 1 a realisiert.The hinge device 4 is designed as a hinge joint. The tilting axis X defined by the articulation device 4 extends close to the downstream end region of the suction head 1, as seen in the sheet running direction BLR. In this embodiment, the articulation device 4 is designed as a film or film hinge. About this film or film hinge of the suction head 1 is coupled via a fastening means shown here only as an example as a screw 6 with a Saugerfingerbasis 7. In this embodiment, the stopper 5 is realized directly by this Saugerfingerbasis 7 in conjunction with an integrated into the suction head 1 or coupled to this structure 1 a.

Wie aus Figur 2 ersichtlich, befindet sich im Innenbereich der Saugerfingerbasis 7 eine axial verkürz- oder stauchbare Luftleitungseinrichtung 8. Die Luftleitungseinrichtung 8 ist bei diesem Ausführungsbeispiel als Faltenbalg-Schlauch ausgebildet. Dieser Faltenbalg-Schlauch verkürzt sich aktiv, sobald die Bogenauflagefläche 2 des Saugerkopfes 1 von einem Hinterkantenbereich des zu ergreifenden Bogens abgedeckt wird und kippt dabei den Saugerkopf 1 aktiv gegen die Anschlagfläche 5. Der in diesem Zustand durch den Saugerkopf 1 sicher ergriffene und definiert um den Schwenkwinkel S zurückgekippte Hinterkantenbereich des Bogens kann nunmehr in an sich bekannter Weise durch zwangsweise Führung der Saugerfingerbasis 7 in einen, einem Greifersystem zugänglichen Greiferbereich hineinbewegt werden (siehe hierzu insbesondere DE 40 12 497 A1 ).How out FIG. 2 can be seen, located in the interior of the Saugerfingerbasis 7 axially shortened or compressible air duct means 8. The air duct means 8 is formed in this embodiment as a bellows hose. This bellows tube is actively shortened as soon as the sheet support surface 2 of the cleaner head 1 is covered by a trailing edge region of the sheet to be gripped and tilts the suction head 1 actively against the stop surface 5. The securely gripped in this state by the suction head 1 and defined by the pivot angle S back-tilted region of the bow can now be moved in a conventional manner by forcibly guiding the Saugerfingerbasis 7 in a gripper system accessible gripper area (see in particular DE 40 12 497 A1 ).

In Figur 3 ist nochmals eine bevorzugte Gestaltung der in dem Saugerkopf 1 verlaufenden Saugkavernen 3 dargestellt. Die durch den Saugerkopf 1 erreichte Haltewirkung beruht darauf, dass der auf der Bogenauflagefläche 2 aufliegende Bogenabschnitt durch den, auf die der Bogenauflagefläche 2 abgewandte Rückseite des Bogens wirkenden Umgebungsdruck gegen die Bogenauflagefläche 2 gedrängt wird. Die Bogenauflagefläche 2 ist vorzugsweise aus einem Material gefertigt, das unter Wirkung der durch die Druckdifferenz herbeigeführten Druckkräfte ein hinreichendes Querkraftübertragungsvermögen sichergestellt ist.In FIG. 3 is again a preferred embodiment of the running in the suction head 1 Saugkavernen 3 shown. The holding effect achieved by the suction head 1 is based on the fact that the sheet section resting on the sheet support surface 2 is urged against the sheet support surface 2 by the ambient pressure acting on the rear side of the sheet facing away from the sheet support surface 2. The sheet support surface 2 is preferably made of a material which ensures a sufficient lateral force transmission capacity under the effect of the pressure difference brought about by the pressure difference.
