Description

Die Erfindung betrifft eine Vorrichtung zum Aufnehmen eines Hilfsstapels beim Fördern von Bogen in einer drucktechnischen Maschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for receiving an auxiliary stack when conveying sheets in a printing machine according to the preamble of claim 1.

In DE 41 29 164 C1 ist eine Einrichtung zur Vereinigung eines Restbogenstapels und eines Hauptbogenstapels im Anleger einer Bogendruckmaschine beschrieben. Die Einrichtung umfasst eine Tragplatte für den Restbogenstapel, die an ihrer Oberseite rechteckförmige Nuten aufweist. Zum vorrübergehenden Tragen des Reststapels sind im Abstand der Nuten starre, gerade, rechteckförmige Stäbe vorgesehen. Die Stäbe sind starr an einer Traverse befestigt.In DE 41 29 164 C1 a device for combining a remaining sheet stack and a main sheet pile is described in the feeder of a sheet-fed press. The device comprises a support plate for the remaining sheet stack, which has rectangular grooves on its upper side. To temporarily carry the rest of the stack rigid, straight, rectangular rods are provided at a distance of the grooves. The rods are rigidly attached to a crossbeam.

Die DE 197 38 029 A1 beinhaltet einen Bogenanleger für eine Druckmaschine mit einem Hilfsstapeltisch, in dem parallel zueinander angeordnete und in die Ebene eines Stapels einführbare Stäbe vorgesehen sind. Bei einer ersten Ausführungsform wird eine elastische Stabaufhängung in Form einer biegsamen Traverse verwendet. Die elastische Aufhängung bewirkt, dass beim Herausziehen des Hilfsstapeltisches aus dem Bogenanleger zwischen den Stäben eine Wegdifferenz vorhanden ist. Bei einer weiteren Ausführungsform sind ein Teil der Stäbe fest an einer Traverse befestigt, während ein anderer Teil der Stäbe über Federn der Traverse zugeordnet sind. Jeder Feder ist eine Stabführung zugeordnet, in der ein Stab in Längsrichtung gleiten kann.The DE 197 38 029 A1 includes a sheet feeder for a printing press with an auxiliary stacking table, in which are arranged parallel to each other and insertable in the plane of a stack rods. In a first embodiment, an elastic rod suspension in the form of a flexible traverse is used. The elastic suspension causes that when removing the auxiliary stacking table from the sheet feeder between the bars a path difference is present. In another embodiment, a portion of the rods are fixedly secured to a crossbar, while another part of the rods are associated with springs of the crosshead. Each spring is associated with a rod guide in which a rod can slide in the longitudinal direction.

Zum Einführen der Stäbe in die Nuten wird die Traverse mit einem Antrieb bewegt. Dabei bestehen hohe Anforderungen an die Abmessungen und Abstände der Nuten und Stäbe und an das Positioniersystem für die Traverse. Um die Stäbe möglichst frei in die Nuten führen zu können, muss ein hoher Aufwand an Kosten und Material getrieben werden.To insert the rods into the grooves, the crosshead is moved by a drive. There are high demands on the dimensions and distances of the grooves and rods and on the positioning system for the traverse. In order to be able to guide the bars as freely as possible into the grooves, a high expenditure on costs and material must be driven.

Bei dem Stapeltisch mit einer Einrichtung zum Erneuern eines Stapels während des fortlaufenden Betriebes einer bogenverarbeitenden Maschine nach DE 42 15 791 A1 werden als Ablageelemente für einen Hilfsstapel selbsttragende Ketten verwendet. Die Ketten sitzen in paralleler Anordnung auf Kettenrädern. Zum Einführen der Kettenenden in die Nuten eines Stapelbrettes ist ein Motor vorgesehen, der an die Kettenräder angreift, und Leitbleche und Rohrstücke, um die Ketten zu führen. Die Beweglichkeit der Ketten ist durch die Geometrie der Kettenräder und Kettenglieder vorgegeben.In the stacking table with means for renewing a stack during the continuous operation of a sheet processing machine DE 42 15 791 A1 are used as storage elements for an auxiliary pile self-supporting chains. The Chains sit in parallel arrangement on sprockets. To insert the chain ends into the grooves of a stacking board, a motor is provided which engages the sprockets, and baffles and pipe sections to guide the chains. The mobility of the chains is determined by the geometry of the sprockets and chain links.

Aufgabe der Erfindung ist es eine Vorrichtung zum Aufnehmen eines Hilfsstapels beim Fördern von Bogen in einer drucktechnischen Maschine zu entwickeln, die eine Verringerung von Zwangskräften bei der Führung von Tragelementen ermöglicht.The object of the invention is to develop a device for receiving an auxiliary stack when conveying sheets in a printing machine, which allows a reduction of constraining forces in the management of support elements.

Die Aufgabe wird mit einer Vorrichtung gelöst, welche die Merkmale nach Anspruch 1 aufweist. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The object is achieved with a device having the features of claim 1. Advantageous embodiments emerge from the subclaims.

Die Erfindung beruht darauf, dass an einer Traverse angeordnete Tragelemente für einen Hilfsstapel in mindestens zwei Freiheitsgraden gelenkig an der Traverse befestigt sind. Die Erfindung ist besonders vorteilhaft bei Vorrichtungen anwendbar, bei denen als Tragelemente gelenkig verbundene Glieder verwendet werden, die auf einer gekrümmten Bahn beweglich sind. Bei dieser Variante beansprucht die Vorrichtung ein geringes Volumen. Die Enden der Tragelemente können über Gelenke in Aussparungen der Traverse befestigt sein. Die Wände einer Aussparung können gleichzeitig Anschläge für die Bewegung eines Tragelementes bilden. Um mit möglichst wenigen Zwangskräften arbeiten zu können, kann ein Tragelement über ein Gelenk mit einer Traverse gekoppelt sein, welches eine Bewegung in vier Freiheitsgraden zulässt. Insbesondere kann zwischen Traverse und einem Tragelement ein Kreuzgelenk vorgesehen sein. Wenn zum Tragen eines Stapels eine Palette verwendet wird, die Nuten aufweist, in der die Tragelemente positioniert werden, dann können die Tragelemente in Richtung der Bewegung aus den Nuten in Grenzen verschiebbar in der Traverse angeordnet sein. Dabei können die Tragelemente paarweise verschiedene Grenzbereiche für die Verschiebung aufweisen.The invention is based on the fact that arranged on a cross member supporting elements for an auxiliary stack in at least two degrees of freedom are hinged to the cross member. The invention is particularly advantageously applicable to devices in which articulated links are used as support elements that are movable on a curved path. In this variant, the device requires a small volume. The ends of the support members may be secured via joints in recesses of the crossbar. The walls of a recess can simultaneously form stops for the movement of a support element. To be able to work with as few coercive forces as possible, a support element can be coupled via a joint with a crossbeam, which allows a movement in four degrees of freedom. In particular, a universal joint can be provided between the traverse and a support element. When a pallet having grooves in which the support members are positioned is used to support a stack, then the support members may be slidably disposed within the crosshead in the direction of movement out of the grooves. In this case, the support elements may have in pairs different border areas for the shift.

Das Druckwerk 2 enthält ein Farbwerk 3, ein Feuchtwerk 4, einen Formzylinder 5, einen Übertragungszylinder 6, einen Druckzylinder 7, einen Zuführzylinder 8 und eine Transporttrommel 9. Zum Anleger 1 gehört eine Palette 10, auf der sich ein Stapel 11 befindet. Die Palette 10 liegt auf einem Stapeltisch 12, der mit Hilfe von Ketten 13, 14 eines Kettengetriebes in vertikaler Richtung 15 positionierbar ist. Um das Erneuern des Stapels 11 während des laufenden Betriebes der Bogenoffsetdruckmaschine zu ermöglichen, ist eine Hilfsstapelvorrichtung vorgesehen. Die Hilfsstapelvorrichtung besteht aus einem Halter 16 für mehrere parallel angeordnete Tragelemente 17, einer Vorschubeinrichtung 18 und einer Führung 19 für die Tragelemente 17 und einer vorderen Tragschiene 20. Der Halter 16 ist mittels Ketten 21 eines Kettengetriebes zusammen mit der Führung 19 und der Vorschubeinrichtung 18 in vertikaler Richtung positionierbar und mittels einer nicht dargestellten Positioniervorrichtung in horizontaler Richtung senkrecht zur Zeichnungsebene der Fig. 1 positionierbar. Die Tragschiene 20 ist mittels Ketten 22 eines Kettengetriebes in vertikaler Richtung 15 positionierbar. Die Palette 10 besitzt Stege und Nuten. Der Stapel 11 liegt auf den Stegen der Palette 10 auf. Durch die Nuten hindurch sind mittels der Vorschubeinrichtung die Tragelemente 17 soweit positionierbar, dass sie auf der Tragschiene 20 aufliegen.In Fig. 1 schematically a feeder 1 and a first printing unit 2 of a sheet-fed offset printing machine is shown. The printing unit 2 includes an inking unit 3, a dampening unit 4, a forme cylinder 5, a transfer cylinder 6, a printing cylinder 7, a feed cylinder 8 and a transport drum 9. The feeder 1 includes a pallet 10, on which a stack 11 is located. The pallet 10 is located on a stacking table 12 which is positionable by means of chains 13, 14 of a chain transmission in the vertical direction 15. In order to enable the renewal of the stack 11 during the operation of the sheetfed offset printing press, an auxiliary stacking device is provided. The auxiliary stacking device consists of a holder 16 for a plurality of parallel arranged support elements 17, a feed device 18 and a guide 19 for the support members 17 and a front support rail 20. The holder 16 is connected by means of chains 21 of a chain transmission together with the guide 19 and the feed device 18 in vertical direction can be positioned and by means of a positioning device, not shown in the horizontal direction perpendicular to the plane of the drawing Fig. 1 positionable. The support rail 20 can be positioned by means of chains 22 of a chain transmission in the vertical direction 15. The pallet 10 has webs and grooves. The stack 11 rests on the webs of the pallet 10. Through the grooves through the support means 17, the support members 17 can be positioned so far that they rest on the support rail 20.

Beim Drucken wird der Stapel 11 mit den Ketten 13, 14 entsprechend der Druckgeschwindigkeit gegen einen Saugkopf 23 mit Sauggreifern 24, 25 geführt. Zu den Sauggreifern 24, 25 führen Saugluftleitungen 26. Die Sauger 23 sind in horizontaler Richtung 27 hin- und hergehend beweglich. Mit den Sauggreifern 24, 25 werden die auf dem Stapel 11 oben liegenden Bogen 28 vereinzelt und durch die Bewegung der Sauger 23 auf einen Anlegertisch 29 gegen Vordermarken 30 gefördert. Von den Vordermarken 30 werden die Bogen 28 mittels eines Schwinggreifers 31 an den Zuführzylinder 8 übergeben. Beim Durchführen durch den Spalt zwischen Druckzylinder 7 und Übertragungszylinder 6 wird der Bogen 28 bedruckt. Mit der Transporttrommel 9 erfolgt der Transport zu weiteren Druckwerken.During printing, the stack 11 is guided with the chains 13, 14 corresponding to the printing speed against a suction head 23 with suction pads 24, 25. To the suction pads 24, 25 lead suction air lines 26. The suckers 23 are in the horizontal direction 27 reciprocally movable. With the suction pads 24, 25 are on the stack 11 overhead sheet 28 isolated and promoted by the movement of the sucker 23 on a feeder table 29 against leading 30 marks. Of the front marks 30, the sheets 28 are transferred by means of a swing gripper 31 to the feed cylinder 8. When passing through the gap between the impression cylinder 7 and transfer cylinder 6, the sheet 28 is printed. With the transport drum 9, the transport to other printing units.

Bei der in Fig. 1 gezeigten Höhenposition des Stapeltisches 12 ist der Zeitpunkt für das Erneuern des Stapels 11 erreicht. Zum Erneuern des Stapels 11 wird der Hilfsstapel 11 mit einem Rest von Bogen 28 zeitweise auf den Tragelementen 17 aufgenommen. Hierzu wird der Halter 16 mit den Tragelementen 17 in vertikaler und horizontaler Richtung so positioniert, dass die Spitzen 32 der Tragelemente 17 etwa auf die Mitten der Querschnittsflächen der Palettennuten weisen. Danach wird die Vorschubeinrichtung 18 mit einem Motor 33 und einem Getriebe 34 in Betrieb gesetzt, so dass die an einer Traverse 35 befestigten Tragelemente 17 durch die Palettennuten hindurch auf die Tragschiene 20 gelangen. Die Tragelemente 17 bestehen aus gelenkig verbundenen Gliedern 36, die außerhalb der Palettennuten und einer Führung im Halter 16 der gekrümmten Form der Führung 19 folgen. Nach dem Durchgang durch die Führung im Halter 16 und nach dem Aufliegen auf der Tragschiene 20 sind die Glieder der Tragelemente 17 biegesteif für die Last des Hilfsstapels 11. Das Heranführen des Hilfsstapels 11 an die Sauggreifer 24, 25 geschieht im weiteren durch vertikalen Antrieb des Halters 16 und der Tragschiene 20 über die Kettengetriebe an den Ketten 21, 22. Dabei ist der Hilfsstapel 11 mit seinem Gewicht vollständig auf den Tragelementen 17 aufgenommen. Während dem Heranführen des Hilfsstapels an den Saugkopf 23 mittels der Ketten 21, 22 wird der Stapeltisch 12 mit der Palette 10 über die Kettengetriebe an den Ketten 13,14 abgesenkt, bis er eine untere Position für die Aufnahme eines neuen Hauptstapels einnimmt. Noch bevor der Hilfsstapel 11 abgearbeitet ist, wird der neue Hauptstapel unter die Tragelemente 17 des Hilfsstapels herangeführt, so dass Hauptstapel und Hilfsstapel 11 fluchten. Anschließend werden die Tragelemente 17 mittels der Vorschubeinrichtung 18 in Richtung der Führung 19 eingezogen, so dass sich Hilfsstapel 11 und der neue Hauptstapel zu einem Stapel 11 vereinigen. Das weitere Heranführen des vereinigten Stapels 11 an den Saugkopf 23 geschieht mittels dem Kettengetriebe und den Ketten 13, 14.At the in Fig. 1 shown height position of the stacking table 12, the time for renewing the stack 11 is reached. To renew the stack 11, the auxiliary stack 11 is temporarily held on the support elements 17 with a remainder of the sheet 28. For this purpose, the holder 16 is positioned with the support members 17 in the vertical and horizontal directions so that the tips 32 of the support members 17 point approximately to the centers of the cross-sectional areas of the pallet grooves. Thereafter, the feed device 18 is set with a motor 33 and a gear 34 in operation, so that the attached to a cross member 35 support members 17 pass through the pallet grooves on the support rail 20. The support members 17 are made of articulated members 36 which follow outside of the pallet grooves and a guide in the holder 16 of the curved shape of the guide 19. After passing through the guide in the holder 16 and after resting on the support rail 20, the members of the support members 17 are rigid for the load of the auxiliary stack 11. The approach of the auxiliary stack 11 to the suction pads 24, 25 is done in the other by vertical drive of the holder 16 and the support rail 20 via the chain transmission on the chains 21, 22. In this case, the auxiliary stack 11 is completely taken up with its weight on the support elements 17. During the approach of the auxiliary stack to the suction head 23 by means of the chains 21, 22, the stacking table 12 is lowered with the pallet 10 via the chain drive on the chains 13, 14 until it assumes a lower position for receiving a new main stack. Even before the auxiliary stack 11 has been processed, the new main stack is brought under the support elements 17 of the auxiliary stack, so that the main stack and auxiliary stack 11 are aligned. Subsequently, the support elements 17 are retracted by means of the feed device 18 in the direction of the guide 19, so that auxiliary stack 11 and the new main stack to a stack 11th unite. The further approach of the united stack 11 to the suction head 23 by means of the chain transmission and the chains 13, 14th

Wenn in der nachstehenden Beschreibung bereits eingeführte Bezugszeichen verwendet werden, dann handelt es sich jeweils um Elemente mit äquivalenter Funktion.If reference numerals already introduced in the description below are used, they are elements having equivalent functions.

Fig. 2 zeigt die Tragelemente 17 an der Traverse 35. Die Traverse 35 besitzt Aussparungen 37, in denen die Enden der Tragelemente 17 befestigt sind. Die Tragelemente 17 sind in gestreckter Form in Nuten 38 der Palette 10 eingefahren, was näher in Fig. 3 gezeigt ist. Sowohl die Spitzen 32 der Tragelemente 17 als auch die Nuten 38 besitzen Einführschrägen 39, 40. Fig. 2 shows the support members 17 on the cross member 35. The cross member 35 has recesses 37, in which the ends of the support members 17 are attached. The support members 17 are retracted in an extended form in grooves 38 of the pallet 10, which is closer in Fig. 3 is shown. Both the tips 32 of the support elements 17 and the grooves 38 have chamfers 39, 40th

In den Fig. 4, 5 sind zwei Ansichten mit Details dargestellt, wie die Traverse 35 in der Führung 19 angeordnet ist. Die Traverse 35 wird beidseitig mit Rollen 41, 42 auf einer Rollenbahn 43 geführt. Zum Vorwärts- und Rückwärtsbewegen der Traverse 35 in der Führung 19 ist die Traverse 35 über Stifte 44, 45 mit Ketten 46, 47 gekoppelt. Die Ketten 46, 47 gleiten in der Führung 19 und stehen mit dem Getriebe 34 in Verbindung.In the Fig. 4, 5 two views are shown with details how the cross member 35 is arranged in the guide 19. The cross member 35 is guided on both sides with rollers 41, 42 on a roller conveyor 43. For forward and backward movement of the cross member 35 in the guide 19, the cross member 35 is coupled via pins 44, 45 with chains 46, 47. The chains 46, 47 slide in the guide 19 and communicate with the gear 34.

Die Figuren 6 und 7 zeigen eine gelenkige Anbindung eines Tragelements 17 an der Traverse 35. In den Aussparungen 37 der Traverse 35 sind Kreuzgelenke 48 angeordnet. Das Ende des Tragelements 17 ist um die Achse eines Stiftes 49 schwenkbar gelagert. Der Stift 49 sitzt auf einer Seite eines doppelgabelförmigen Verbindungsstücks 50. Auf der anderen Seite des Verbindungsstücks 50 ist ein Bolzen 55 vorgesehen, dessen Achse parallel zur Achse des Stiftes 49 steht. Ein weiterer Stift 51 durchdringt den Bolzen 55 in einer Richtung senkrecht zur Achse des Stiftes 49. Der Stift 51 ist weiterhin in einem Bolzen 52 mit gabelförmigen Enden gehalten. Der zylindrische Bolzen 52 ist drehbar in einer Bohrung der Traverse 35 gelagert. Ein Ansatz 53 des Bolzens 52 und ein Sicherungsring 54 verhindern eine Verschiebung des Bolzen 52 in Achsrichtung. Das Tragelement 17 und das Verbindungsstück 50 sind um die Achse des Stiftes 51 schwenkbar. Die Schwenkbewegung des Tragelements 17 um die Achsen der Stifte 49, 51 und die Drehung um die Achse der Bolzen 52, 55 wird durch die Innenwandungen der Aussparungen 37 begrenzt.The FIGS. 6 and 7 show an articulated connection of a support member 17 to the cross member 35. In the recesses 37 of the cross member 35, universal joints 48 are arranged. The end of the support member 17 is pivotally mounted about the axis of a pin 49. The pin 49 is seated on one side of a double-forked connecting piece 50. On the other side of the connecting piece 50, a bolt 55 is provided, the axis of which is parallel to the axis of the pin 49. Another pin 51 penetrates the pin 55 in a direction perpendicular to the axis of the pin 49. The pin 51 is further held in a bolt 52 with forked ends. The cylindrical bolt 52 is rotatably mounted in a bore of the cross member 35. A projection 53 of the bolt 52 and a locking ring 54 prevent displacement of the bolt 52 in the axial direction. The support member 17 and the connector 50 are pivotable about the axis of the pin 51. The pivotal movement of the support member 17 about the axes of the pins 49, 51st and the rotation about the axis of the bolts 52, 55 is limited by the inner walls of the recesses 37.

Beim Einführen der Tragelemente 17 in die Nuten 38 der Palette 10 werden zu hohe Zwangskräfte auf die Tragelemente 17 bzw. die Palette 10 vermieden, weil bereits bei geringfügigen Zwangskräften die Tragelemente 17 dem Widerstand ausweichen, indem eine Bewegung der Tragelemente 17 im Rahmen der durch die Gelenke 48 und die Wandung der Aussparungen 37 vorhandenen Freiheitsgrade stattfindet.When inserting the support members 17 in the grooves 38 of the pallet 10 too high constraining forces on the support members 17 and the pallet 10 are avoided because even with slight constraining forces the support members 17 dodge the resistance by a movement of the support members 17 in the context of by Joints 48 and the wall of the recesses 37 degrees of freedom takes place.

In Fig. 8 ist eine Ausführungsform gezeigt, bei der einige der Tragelemente 17 in der Traverse 35 ein Spiel x aufweisen, weil die Länge des Bolzens 52 gegenüber Fig. 6, 7 etwas vergrößert ist. Wenn die Tragelementen 17 unter dem Stapel 11 herausgezogen werden, dann beginnt das Herausziehen bei Tragelementen 17 mit Spiel x etwas später als bei Tragelementen 17 ohne Spiel. Durch eine unterschiedliche Größe des Spiels x kann jedes Tragelement 17 zu einem anderen Zeitpunkt herausgezogen werden. Das Spiel x kann über die Breite eines Bogens 28 bei Tragelementpaaren 17 symmetrisch zur Bogenmitte gleich groß vorgesehen werden.In Fig. 8 an embodiment is shown in which some of the support members 17 in the cross member 35 have a game x, because the length of the bolt 52 opposite Fig. 6, 7 something is enlarged. When the support members 17 are pulled out from under the stack 11, pulling out begins at support members 17 with clearance x slightly later than support members 17 without play. By a different size of the game x each support member 17 can be pulled out at a different time. The game x can be provided over the width of an arc 28 in support element pairs 17 symmetrically to the center of the same size.
