Abstract

In a sheet guide element adjusting device in rotary printing machines, the object consists in adapting the sheet guide elements to the different format widths transversely to the sheet running direction by means of a central adjustment. This object is achieved according to the invention in that the sheet guide elements arranged on a holder are displaceable by a different amount in their spacing from one another by an axial movement of one of the sheet guide elements. Due to the action of a force on the tab (46) in the direction of the arrow A, the shaft (48) held in the hollow profile (36) and provided with helical grooves, undergoes a rotary movement in that the groove (49) is moved about a guide pin (58) of the sheet guide element (37). The other sheet guide elements (38) to (43) are inevitably carried along and, as a result of the different pitch of the grooves (49, 51, 52, 53, 54, 56), assume a position between the maximum position (37) to (43) and a minimum position (37') to (43') depending on the sheet format to be adjusted. By means of this solution, different sheet format widths can be adjusted by means of a simple drive. <IMAGE>

Description

Die Erfindung betrifft eine Einrichtung zum Verstellen von Bogenleitelementen in Rotationsdruckmaschinen gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a device for adjusting sheet guiding elements in rotary printing machines according to the preamble of patent claim 1.

Gemäß DE-OS 26 57 250 ist eine Bogenleiteinrichtung zur Bogenführung an Schön- und Widerdruckmaschinen bekannt, bei welcher die axiale Verstellung mehrerer, in Bogenlaufrichtung hintereinander angeordneter Bogenleitbügel durch den Stellantrieb eingeleitet wird. Bei Betätigung des Stellantriebes wird die Stellkette über eine Flachgliederkette und eine Transmissionswelle bewegt, so daß sich ein mit der Stellkette verbundener Rollwagen längs einer Traverse bewegt. Nachteilig an dieser Bogenleiteinrichtung ist der große getriebetechnische Aufwand, welcher insbesondere bei mehreren über die Maschinenbreite parallel angeordneten Bogenleiteinrichtungen so hoch wird, daß die gemeinsame Verstellung mehrerer Bogenleiteinrichtungen zusammen nicht mehr vertretbar ist.According to DE-OS 26 57 250, a sheet guiding device for sheet guiding on perfecting machines is known, in which the axial adjustment of a plurality of sheet guiding bars arranged one behind the other in the direction of sheet travel is initiated by the actuator. When the actuator is actuated, the actuating chain is moved via a flat link chain and a transmission shaft, so that a trolley connected to the actuating chain moves along a traverse. A disadvantage of this sheet guiding device is the large expenditure on gear technology, which becomes so high, in particular with several sheet guiding devices arranged in parallel across the machine width, that the joint adjustment of several sheet guiding devices together is no longer justifiable.

Weiterhin ist gemäß DE-OS 15 61 101 eine Bogenleiteinrichtung für Bogenführungszylinder bekanntgeworden, bei welcher in Bogenlaufrichtung parallel zueinander angeordnete Bogenleitbügel mit Luftaustrittsöffnungen angeordnet sind. Derartige Bogenleitbügel müssen bei Papierformatänderung auf ihrer Halterung separat dem neuen Papierformat angepaßt werden. Nachteilig ist hierbei der hohe Zeitaufwand bei der Umrüstung der Druckmaschine.Furthermore, according to DE-OS 15 61 101, a sheet guiding device for sheet guiding cylinders has become known, in which sheet guiding brackets with air outlet openings are arranged parallel to one another in the direction of sheet travel. Such When changing the paper format, sheet guide bars must be adapted separately to the new paper format on their holder. The disadvantage here is the high expenditure of time when converting the printing press.

Ähnlich sind Papierniederhalter einer Papierführung bei Druckmaschinen gemäß DE-OS 17 86 196 ausgeführt, welche ebenfalls bei Papierformatverstellung unter hohem Zeitaufwand verstellt werden müssen.Paper hold-down devices of a paper guide in printing presses according to DE-OS 17 86 196 are similarly designed, which also have to be adjusted in a time-consuming manner when changing the paper format.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Bogenleitelemente quer zur Bogenlaufrichtung mittels einer zentralen Verstellung den verschiedenen Formatbreiten anzupassen.The object of the present invention is to adapt the sheet guiding elements to the different format widths transversely to the sheet running direction by means of a central adjustment.

Diese Aufgabe wird erfindungsgemäß durch das Kennzeichen des Patentanspruches 1 gelöst.This object is achieved by the characterizing part of patent claim 1.

Durch die Anwendung der erfindungsgemäßen Lösung werden insbesondere nachfolgende Vorteile erzielt. Durch einen technisch einfachen und wenig Platz beanspruchenden Antrieb können die Bogenleitelemente auf eine neue Formatbreite eingestellt werden. Die sich bewegenden Teile, nämlich die Welle mit den am Umfang befindlichen Nuten sind vor Papierstaub und dgl. Verunreinigungen geschützt, indem diese Teile in einem Hohlprofil angeordnet sind. Dieses Hohlprofil ist gleichzeitig die Führung der Bogenleitelemente.The following advantages are achieved in particular by using the solution according to the invention. Thanks to a technically simple drive that takes up little space, the sheet guiding elements can be set to a new format width. The moving parts, namely the shaft with the grooves on the circumference, are protected from paper dust and the like. Contamination by arranging these parts in a hollow profile. This hollow profile is also the guide of the sheet guide elements.

Vor der Stopptrommel 4 ist ebenfalls eine Bogenleiteinrichtung 32 in Form eines Niederhalters angeordnet.1, a sheet-fed rotary printing press with two printing units is shown in a side view. A sheet feeder is connected to a stop drum 4 via a sheet feeder 2 and an abutment cross 3. In a first printing unit there is a transfer drum 6 and a printing cylinder 7 with a rubber cylinder 8 and a plate cylinder 9 arranged above it. Between the first and second printing units there is a sheet transfer drum 10. This is followed in turn by a printing cylinder 11 with a rubber cylinder 12 arranged above it and a plate cylinder 13 . At the sprocket 14 close the pressure cylinder 11; 16 on, over which the gripper chain system 17 is guided in the sheet delivery 18. A suction roller 19 is arranged in the sheet delivery 18. All mentioned cylinders, drums and the like are in the side wall 21; 22 of the machine frame stored. Ink and dampening systems as well as controls that are not directly related to the invention are not shown. On the circumference of the transfer drum 6, on the printing cylinder 7, the sheet transfer drum 10, the printing cylinder 11 and on the chain wheel 14 up to the suction roller 19, sheet guiding devices 23 to 31 are attached. A sheet guiding device 32 in the form of a hold-down device is also arranged in front of the stop drum 4.

Gemäß Fig. 2 ist stellvertretend für die Bogenleiteinrichtungen 23 bis 32 an der Bogenleiteinrichtung 32 eine Draufsicht auf eine erfindungsgemäße Lösung gezeigt. Eine am Maschinengestell 21; 22 befestigte Halterung 33; 34 trägt ein Profil 36, welches als quadratisches Hohlprofil ausgeführt ist. Auf dem Profil 36 befinden sich verschiebbare Bogenleitelemente 37; 38; 39; 41; 42; 43, welche symmetrisch zur Symmetrielinie 44 in der Maschinenmitte angeordnet sind in einer Stellung zur Führung eines Bogens mit maximaler Formatbreite. Die gestrichelte Darstellung der Bogenleitelemente in den Positionen 37' bis 43' zeigt die Stellung zur Führung eines Bogens mit minimaler Formatbreite an. Die Verstellung der Bogenleitelemente 37 bis 43 in die Position 37' bis 43' erfolgt an einer Lasche 46 in Pfeilrichtung A über einen nicht dargestellten Motor mit Gewindespindel oder einen Pneumatikzylinder, der über ein Proportionalventil angesteuert sein kann. Das Bogenleitelement 37 als Einzelheit gemäß Fig. 2 ist in Fig. 3 in vergrößerter Darstellung und in Fig. 4 als Schnitt IV - IV gemäß Fig. 3 gezeigt.2, a top view of a solution according to the invention is shown representative of the sheet guiding devices 23 to 32 on the sheet guiding device 32. One on the machine frame 21; 22 attached bracket 33; 34 carries a profile 36, which is designed as a square hollow profile. Slidable sheet guiding elements 37 are located on the profile 36; 38; 39; 41; 42; 43, which are arranged symmetrically to the line of symmetry 44 in the middle of the machine in a position for guiding an arc with a maximum format width. The dashed representation of the sheet guide elements in positions 37 'to 43' shows the position for guiding an arc with a minimal format width. The adjustment of the sheet guide elements 37 to 43 in the Positions 37 'to 43' take place on a tab 46 in the direction of arrow A via a motor, not shown, with a threaded spindle or a pneumatic cylinder, which can be controlled via a proportional valve. The sheet guiding element 37 as a detail according to FIG. 2 is shown in an enlarged illustration in FIG. 3 and as a section IV-IV according to FIG. 3 in FIG. 4.

Das Bogenleitelement 37 besteht aus einer Halterung in Form einer Hülse 47, welche auf dem Profil 36 verschiebbar angeordnet ist. In dem Profil 36 befindet sich eine Welle 48, welche Nuten 49; 51; 52; 53; 54; 56 endlicher Länge aufweist, die sich mit verschieden großer Steigung wendel- oder spiralförmig um die Welle 48 erstrecken. Die Nuten 49 bis 52 und 53 bis 56 sind spiegelbildlich zur Symmetrielinie 44 Maschinenmitte angeordnet. Die Nuten 52; 53 weisen die größte Steigung auf, die Nuten 49; 56 besitzen die geringste Steigung.The sheet guiding element 37 consists of a holder in the form of a sleeve 47 which is arranged on the profile 36 so as to be displaceable. In the profile 36 there is a shaft 48, which grooves 49; 51; 52; 53; 54; 56 has a finite length, which extend with different pitches in a helical or spiral shape around the shaft 48. The grooves 49 to 52 and 53 to 56 are arranged in mirror image to the line of symmetry 44 machine center. The grooves 52; 53 have the greatest slope, the grooves 49; 56 have the smallest incline.

Gemäß Fig. 4 weist die im Querschnitt quadratisch ausgeführte Hülse 47 eine Verstärkung mit Innengewinde 57 auf, worin ein Führungsstift 58 eingeschraubt ist. Der Führungsstift 58 ragt durch einen Schlitz 59 im Profil 36 und greift mit seinem Ende in die Nut 49 gemäß Fig. 5 ein. Das Bogenleitelement 37 besteht weiterhin aus einem Bügel 61, der mit seinem einen Ende mit der Hülse 47, beispielsweise durch Schweißen, fest verbunden ist. Das andere Ende des Bügels 61 ist in seiner Längsachse leicht geneigt und nimmt ein Klemmelement 62 auf für das Einspannen eines Haltebleches 63, welches einen Bogen 64 gegen die Anlagetraverse 3 drückt. Die Funktionsweise der Einrichtung ist wie folgt. Durch den Angriff einer Kraft an der Lasche 46 in Pfeilrichtung A, beispielsweise durch einen nicht dargestellten Arbeitszylinder erfährt die Welle 48 eine Drehbewegung, indem sich die Nut 49 um den Führungsstift 58 bewegt. Das Bogenleitelement 37 bewegt sich weiterhin vermittelst des Arbeitszylinders in Pfeilrichtung A auf die Position 37' zu. Die anderen Bogenleitelemente 38 bis 43 werden infolge des Eingreifens ihrer Führungsstifte in die Nuten 51 bis 56 zwangsweise mitgeführt und nehmen je nach dem einzustellenden Bogenformat eine entsprechende Stellung zwischen Maximalstellung 37 bis 43 und Minimalstellung 37' bis 43' ein. Durch die unterschiedliche Steigung der Nuten 49; 51; 52 bzw. der spiegelbildlich dazu verlaufenden Nuten 53; 54; 56 wird eine symmetrische Verstellung der Bogenleitelemente 37 bis 43 mittels eines einfachen Antriebes vorgenommen, obwohl die genannten Bogenleitelemente unterschiedliche Wege zurücklegen. Die Antriebskraft für die Lasche 46 kann auch von einer nicht dargestellten Seitenziehmarke zum seitlichen Ausrichten der Bogen 64 abgenommen werden. Alternativ kann auch eine Drehbewegung direkt auf die Welle 48 wirken. Die Bogenleiteinrichtungen 23 bis 31 gemäß Fig. 1 werden in analoger Weise verstellt.4, the sleeve 47, which has a square cross section, has a reinforcement with an internal thread 57, in which a guide pin 58 is screwed in. The guide pin 58 protrudes through a slot 59 in the profile 36 and engages with its end in the groove 49 according to FIG. 5. The sheet guiding element 37 also consists of a bracket 61, which is firmly connected at one end to the sleeve 47, for example by welding. The other end of the bracket 61 is slightly inclined in its longitudinal axis and receives a clamping element 62 for clamping a holding plate 63 which has an arc 64 presses against the traverse 3. The operation of the facility is as follows. When a force acts on the tab 46 in the direction of the arrow A, for example through a working cylinder (not shown), the shaft 48 undergoes a rotational movement in that the groove 49 moves around the guide pin 58. The sheet guiding element 37 continues to move by means of the working cylinder in the direction of arrow A to position 37 '. The other sheet guide elements 38 to 43 are forcibly carried as a result of the engagement of their guide pins in the grooves 51 to 56 and, depending on the sheet format to be set, assume a corresponding position between maximum position 37 to 43 and minimum position 37 'to 43'. Due to the different slope of the grooves 49; 51; 52 or the grooves 53; 54; 56, the sheet guiding elements 37 to 43 are adjusted symmetrically by means of a simple drive, although the sheet guiding elements mentioned cover different paths. The driving force for the tab 46 can also be taken from a side drawing mark (not shown) for the lateral alignment of the sheets 64. Alternatively, a rotary movement can also act directly on the shaft 48. The sheet guiding devices 23 to 31 according to FIG. 1 are adjusted in an analogous manner.

Ergänzend zu dem Vorgenannten wird noch Folgendes ausgeführt. Die verdrehbare Welle 48 weist auf ihrem Umfang sechs wendelförmige Nuten 49, 51, 52; 53, 54, 56 auf. Die Steigung der Nuten 49, 51, 52; 53, 54, 56 nimmt von der Mitte der Welle 48 zu den Enden der Welle 48 hin ab, so daß jeweils zwei Nuten 49, 56; 51, 54; 52, 53 gleiche Steigungen aufweisen. Die jeweils an den Enden der Welle 48 befindlichen Nuten 49, 56 weisen jedoch einen solchen Steigungswinkel auf, der noch unter der Selbsthemmung liegt. Jeder Nut 49, 51, 52; 53, 54, 56 ist jeweils ein Ring 47 zugeordnet. Jeder Ring 47 weist einen ins Innere des Hohlträgers 36 gerichteten ringfesten Führungsstift 58 auf, der kraft- und formschlüssig in eine der Nuten 49, 51, 52; 53, 54 oder 56 eingreift. Unter Mitte der Welle 48 oder Symmetrielinie Maschinenmitte 44 ist die Mitte der maximalen Formatbreite auf einem Druckwerkszylinder zu verstehen. Die auf dem Umfang des Profiles oder Hohlträgers 36 verschiebbar angeordnete Hülse 47 weist die Form eines Ringes auf. Der Hohlträger 36 sowie die verschiebbar und formschlüssig auf dem Hohlträger 36 angeordneten Ringe 47 können einen beliebigen Querschnitt aufweisen, z. B. quadratischen, rechteckigen oder sechseckigen Querschnitt. Im Regelfall ist zumindest eine Profilkante erforderlich - Tropfenform. Somit ist immer eine Verdrehsicherung zwischen dem Ring 47, welcher jeweils ein Bogenleitelement 37 oder einen Bogenniederhalter trägt und dem Hohlträger 36 gegeben. Es ist auch möglich, den Hohlträger 36 sowie die darauf verschiebbaren Ringe 47 aus hohlem Randprofil herzustellen. Dabei muß jedoch eine zusätzliche Verdrehsicherung durch ein Verbindungselement geschaffen werden. Das Verbindungselement kann aus einem in den kreisförmigen Ring 47 in radialer Richtung eingeschraubten Gewindestift bestehen, welcher mit seinem Stiftteil kraft- und formschlüssig in eine in der Mantelfläche des Hohlträgers 36 verlaufende axiale Nut eingreift. Die Welle 48 kann auch zweiteilig ausgeführt sein, d. h. an der Wellenmitte 44 getrennt sein. Dann erfolgt der Antrieb der Niederhalter 37, 38, 39 durch den Angriff einer Kraft am Niederhalter 37 in axialer Richtung A durch einen Arbeitszylinder oder eine Seitenziehmarke. Das Gleiche gilt sinngemäß für den Antrieb der Bogenleitelemente 43, 42, 41, welche durch den Angriff einer Kraft am Niederhalter 43 in axialer Richtung zur Wellenmitte 44 betätigt werden (Fig. 2).In addition to the above, the following is also stated. The rotatable shaft 48 has six helical grooves 49, 51, 52; 53, 54, 56 on. The slope of the grooves 49, 51, 52; 53, 54, 56 decreases from the center of the shaft 48 to the ends of the shaft 48, so that two grooves 49, 56; 51, 54; 52, 53 have the same gradients. However, the grooves 49, 56 located at the ends of the shaft 48 each have a pitch angle that is still below the self-locking. Each groove 49, 51, 52; 53, 54, 56 are each assigned a ring 47. Each ring 47 has a ring-fixed guide pin 58, which is directed into the interior of the hollow carrier 36 and which fits into one of the grooves 49, 51, 52; 53, 54 or 56 engages. The center of the shaft 48 or line of symmetry of the machine center 44 is to be understood as the center of the maximum format width on a printing group cylinder. The sleeve 47, which is displaceably arranged on the circumference of the profile or hollow support 36, has the shape of a ring. The hollow support 36 and the slidably and positively arranged on the hollow support 36 rings 47 can have any cross section, z. B. square, rectangular or hexagonal cross section. As a rule, at least one profile edge is required - teardrop shape. Thus there is always an anti-rotation device between the ring 47, which carries a sheet guide element 37 or a sheet hold-down device and the hollow support 36. It is also possible to produce the hollow support 36 and the rings 47 which can be moved thereon from a hollow edge profile. However, an additional anti-rotation must be created by a connecting element will. The connecting element can consist of a threaded pin screwed into the circular ring 47 in the radial direction, which engages with its pin part in a non-positive and positive manner in an axial groove running in the lateral surface of the hollow support 36. The shaft 48 can also be designed in two parts, ie be separated at the shaft center 44. Then the hold-down device 37, 38, 39 is driven by the application of a force on the hold-down device 37 in the axial direction A by a working cylinder or a side pulling mark. The same applies analogously to the drive of the sheet guiding elements 43, 42, 41, which are actuated by the application of a force on the hold-down device 43 in the axial direction to the shaft center 44 (FIG. 2).

Es ist auch möglich, zwischen der Halterung 33 und dem einen äußeren Niederhalter 37 ein zusätzliches, dem Niederhalter 37 ähnliches Element einzusetzen, welches kein Klemmelement 62 und kein Halteblech 63 aufweist und mit einem Führungsstift 58 in derselben für den Niederhalter 37 zuständigen äußeren wendelförmigen Nut 49 kraft- und formschlüssig eingreift. In diesem Falle kann der Angriff einer Kraft in axialer Richtung auf dieses Zusatzelement erfolgen. Ein derartiges zusätzliches Element kann auch zwischen der Halterung 34 und dem anderen äußeren Bogenleitelement 42 in gleicher Weise eingesetzt werden.It is also possible to use an additional element, similar to the hold-down device 37, between the holder 33 and the one outer hold-down device 37, which has no clamping element 62 and no holding plate 63 and with a guide pin 58 in the same outer helical groove 49 which is responsible for the hold-down device 37 engages non-positively and positively. In this case, a force can be applied in the axial direction to this additional element. Such an additional element can also be used between the holder 34 and the other outer sheet guiding element 42 in the same way.

Das Bewegen der Bogenleitelemente oder Niederhalter 37, 38, 39; 41, 42, 43 in axialer Richtung kann auch durch eine direkte Verdrehung der Welle 48 erfolgen. Bei einer Trennung der Welle 48 an der Symmetrielinie 44 müssen beide Teile der Welle 48 gesondert verdreht werden.Moving the sheet guide elements or hold-down device 37, 38, 39; 41, 42, 43 in the axial direction can also be done by directly rotating the shaft 48. If the shaft 48 is separated on the line of symmetry 44, both parts of the shaft 48 must be rotated separately.

In jedem Falle wird durch das Verdrehen der mit wendelförmigen Nuten 49, 51, 52, 53, 54, 56 versehenen Welle 48 eine an das Bogenformat angepaßte Einstellung der Niederhalter 37 bis 43 in die Positionen 37' bis 43' erzielt, unabhängig davon, ob die Welle 48 selbst verdreht wird oder eine Verdrehbewegung der Welle 48 durch ein Angreifen einer axialen Kraft an einem am Ende der Welle 48 befindlichen Niederhalter 37, 43 erzeugt wird.In any case, by turning the shaft 48 provided with helical grooves 49, 51, 52, 53, 54, 56, the hold-down device 37 to 43 is adjusted to the positions 37 'to 43' in accordance with the sheet format, regardless of whether the shaft 48 itself is rotated or a rotational movement of the shaft 48 is generated by the application of an axial force on a hold-down device 37, 43 located at the end of the shaft 48.
