Definitions

  • the invention relates to a device for adjusting the rotational position between a fixed gear and an adjusting gear arranged coaxially therewith and for changing the gripper by axially displacing an actuator on a cylinder of the turning device of a sheet-fed rotary printing press.
  • Such a device is known from DE-OS 36 11 325.
  • the adjusting element of this arrangement is adjustable by means of a thread in a way which comprises a first section in which the spring force acting on the pressure levers increases from a low value to a maximum value and a second section in which while maintaining the maximum on the pressure levers spring force acting an electrical switch for the supply circuit of the drive device can be actuated so that the supply circuit can only be closed when the coupling between the fixed gear and the adjusting gear is fully effective.
  • the supply circuit is first interrupted before the frictional coupling between the fixed gear and the adjusting gear can be released. In this way it is ensured that the machine can only be put into operation when the adjusting gear is non-positively coupled to the fixed gear, that is to say when the clamping between the two gears is firmly tightened.
  • the axial displacement of the adjusting member for converting the grippers takes place in a design known from DE-PS 26 20 392 by an eccentric mechanism made of an eccentric bolt rotatably mounted in the adjusting member and an eccentric pin engaging in a guide of the cylinder.
  • the adjusting member is secured with fastening screws in relation to the cylinder, so that it is necessary for the displacement of the adjusting member to climb the printing machine in order to loosen the fastening screws of the adjusting member, the actuating member of the eccentric with a suitable tool from one position to the opposite end position to twist and then tighten the fastening screws again.
  • an electrical end position protection is also known from this document. The end position lock works independently of the previously mentioned securing of the clamping between the fixed gear and the adjusting gear.
  • the object on which the invention is based is derived from securing the changeover process on the turning device better than hitherto against incorrect operation.
  • the aim is to simplify the changeover process in order to reduce set-up times during the changeover process while avoiding incorrect operation.
  • the new training features while maintaining the advantage of a clamping force independent of the operator of the machine for the non-positive coupling of the fixed gear and the adjusting gear, transmit the reaction force of the spring force to at least one clamping body, which firmly connects the adjusting member for the gripper changeover to the cylinder as soon as and as long as the fixed gear is non-positively coupled to the adjusting gear, so that the adjusting member for the gripper changeover in the operating position of the machine is now firmly connected to the cylinder and is thereby mechanically secured as a function of the effective clamping of the two gears. Electrical or mechanical precautions must be taken to ensure that this mechanical protection is only possible in the positioned positions, in particular end positions. This also achieves greater safety because both clamping processes are protected by only one switch, and an electrical signal can be used for the optical and / or acoustic display of the intact clamping.

Description

Die Erfindung betrifft eine Vorrichtung zur Verstellung der Drehlage zwischen einem Festzahnrad und einem dazu gleichachsig angeordneten Verstellzahnrad sowie zur Greiferumstellung durch axiale Verschiebung eines Stellgliedes an einem Zylinder der Wendeeinrichtung einer Bogenrotationsdruckmaschine.The invention relates to a device for adjusting the rotational position between a fixed gear and an adjusting gear arranged coaxially therewith and for changing the gripper by axially displacing an actuator on a cylinder of the turning device of a sheet-fed rotary printing press.

Eine derartige Vorrichtung ist aus der DE-OS 36 11 325 bekannt. Das Verstellorgan dieser Anordnung ist mittels eines Gewindes auf einem Wege verstellbar, welcher einen ersten Abschnitt, in dem die auf die Druckhebel einwirkende Federkraft von einem geringen auf einen maximalen Wert ansteigt, und einen zweiten Abschnitt umfaßt, in dem unter Beibehaltung der maximal auf die Druckhebel einwirkenden Federkraft ein elektrischer Schalter für den Versorgungsstromkreis der Antriebseinrichtung betätigbar ist, so daß der Versorgungsstromkreis nur bei vollständig wirksamer Kupplung zwischen dem Festzahnrad und dem Verstellzahnrad geschlossen sein kann. Umgekehrt erfolgt somit zunächst eine Unterbrechung des Versorgungsstromkreises, bevor die kraftschlüssige Kupplung zwischen dem Festzahnrad und dem Verstellzahnrad gelöst werden kann. Auf diese Weise ist sichergestellt, daß die Maschine nur bei kraftschlüssiger Kupplung des Verstellzahnrades mit dem Festzahnrad, das heißt, bei fest angezogener Klemmung zwischen den beiden Zahnrädern in Betrieb gesetzt werden kann.Such a device is known from DE-OS 36 11 325. The adjusting element of this arrangement is adjustable by means of a thread in a way which comprises a first section in which the spring force acting on the pressure levers increases from a low value to a maximum value and a second section in which while maintaining the maximum on the pressure levers spring force acting an electrical switch for the supply circuit of the drive device can be actuated so that the supply circuit can only be closed when the coupling between the fixed gear and the adjusting gear is fully effective. Conversely, the supply circuit is first interrupted before the frictional coupling between the fixed gear and the adjusting gear can be released. In this way it is ensured that the machine can only be put into operation when the adjusting gear is non-positively coupled to the fixed gear, that is to say when the clamping between the two gears is firmly tightened.

Die axiale Verschiebung des Verstellgliedes zur Umstellung der Greifer erfolgt bei einer aus der DE-PS 26 20 392 bekannten Ausbildung durch eine Exzentermechanik aus einem in dem Verstellglied verdrehbar gelagerten Exzenterbolzen und aus einem in eine Führung des Zylinders eingreifenden Exzenterzapfen. Das Verstellglied ist durch Befestigungsschrauben gegenüber dem Zylinder gesichert, so daß es für die Verschiebung des Verstellgliedes erforderlich ist, die Druckmaschine zu besteigen, um die Befestigungsschrauben des Verstellgliedes zu lösen, das Betätigungsorgan des Exzenters mit einem dazu geeigneten Werkzeug von der einen in die entgegengesetzte Endlage zu verdrehen und anschließend die Befestigungsschrauben wieder fest anzuziehen. Für das am Zylinder axial verschiebliche Verstellglied zur Umstellung der Kurven für die Greifersteuerung ist eine elektrische Endlagenabsicherung ebenfalls aus dieser Druckschrift bekannt. Die Endlagensicherung arbeitet unabhängig von der zuvor genannten Absicherung der Klemmung zwischen dem Festzahnrad und dem Verstellzahnrad.The axial displacement of the adjusting member for converting the grippers takes place in a design known from DE-PS 26 20 392 by an eccentric mechanism made of an eccentric bolt rotatably mounted in the adjusting member and an eccentric pin engaging in a guide of the cylinder. The adjusting member is secured with fastening screws in relation to the cylinder, so that it is necessary for the displacement of the adjusting member to climb the printing machine in order to loosen the fastening screws of the adjusting member, the actuating member of the eccentric with a suitable tool from one position to the opposite end position to twist and then tighten the fastening screws again. For the axially displaceable adjusting member for changing the curves for the gripper control, an electrical end position protection is also known from this document. The end position lock works independently of the previously mentioned securing of the clamping between the fixed gear and the adjusting gear.

Beide Absicherungen, die für die Klemmung des Festzahnrades mit dem Verstellzahnrad und die für die Umstellung der Greifer mit dem axial verschieblichen Verstellglied, erfordern einen eigenständigen Aufbau mit allen dazugehörigen Bauteilen. Bei Anordnungen nach diesem Stande der Technik erfolgt die Umstellung der Wendeeinrichtung an umstellbaren Maschinen für den Schön und Widerdruck umständlich und zeitaufwendig an zwei getrennten Stellen der Maschine, von denen eine an der Maschinenseite und eine im Innern der Maschine liegt, mit voneinander unabhängigen elektrischen Absicherungen.Both safeguards, those for clamping the fixed gearwheel with the adjusting gearwheel and those for converting the grippers with the axially displaceable adjusting member, require an independent construction with all associated components. In the case of arrangements according to this prior art, the conversion of the turning device on convertible machines for perfecting and reverse printing takes place in a complicated and time-consuming manner at two separate locations on the machine, one of which is on the machine side and one inside the machine, with independent electrical safeguards.

Daraus ist die der Erfindung zugrundeliegende Aufgabe abgeleitet, den Umstellvorgang an der Wendeeinrichtung besser als bisher gegen Fehlbedienung abzusichern.From this, the object on which the invention is based is derived from securing the changeover process on the turning device better than hitherto against incorrect operation.

Gleichzeitig wird eine Vereinfachung des Umstellvorganges angestrebt, um dadurch unter Vermeidung von Fehlbedienungen die Rüstzeiten beim Umstellvorgang zu verringern.At the same time, the aim is to simplify the changeover process in order to reduce set-up times during the changeover process while avoiding incorrect operation.

Die Erfindung löst diese Aufgabe mit einer Vorrichtung der eingangs genannten Gattung mit den Merkmalen der Patentansprüche 1 und 8.The invention solves this problem with a device of the aforementioned type with the features of claims 1 and 8.

Durch die neuen Ausbildungsmerkmale wird unter Aufrechterhaltung des Vorteils einer vom Bediener der Maschine unabhängigen Klemmkraft für die kraftschlüssige Kupplung des Festzahnrades und des Verstellzahnrades die Reaktionskraft der Federkraft auf wenigstens einen Klemmkörper übertragen, der das Verstellglied für die Greiferumstellung mit dem Zylinder fest verbindet, sobald und solange das Festzahnrad mit dem Verstellzahnrad kraftschlüssig gekuppelt ist, so daß nunmehr auch das Verstellglied für die Greiferumstellung in der Betriebsstellung der Maschine fest mit dem Zylinder verbunden und dadurch mechanisch in Abhängigkeit von der wirksamen Klemmung der beiden Zahnräder gesichert ist. Dabei sind elektrische oder mechanische Vorkehrungen dafür zu treffen, daß diese mechanische Absicherung nur in den positionierten Lagen, insbesondere Endlagen, möglich ist. Erreicht wird dadurch außerdem mehr Sicherheit, weil beide Klemmvorgänge durch nur einen Schalter abgesichert sind, wobei ein elektrisches Signal zur optischen und/oder akustischen Anzeige der intakten Klemmung verwendet werden kann.The new training features, while maintaining the advantage of a clamping force independent of the operator of the machine for the non-positive coupling of the fixed gear and the adjusting gear, transmit the reaction force of the spring force to at least one clamping body, which firmly connects the adjusting member for the gripper changeover to the cylinder as soon as and as long as the fixed gear is non-positively coupled to the adjusting gear, so that the adjusting member for the gripper changeover in the operating position of the machine is now firmly connected to the cylinder and is thereby mechanically secured as a function of the effective clamping of the two gears. Electrical or mechanical precautions must be taken to ensure that this mechanical protection is only possible in the positioned positions, in particular end positions. This also achieves greater safety because both clamping processes are protected by only one switch, and an electrical signal can be used for the optical and / or acoustic display of the intact clamping.

Das Kennzeichen des Anspruches 2 enthält eine vorteilhafte Ausbildung der Erfindungsmerkmale mit dem Ziel, möglichst einfache Bauteile für die Übertragung der Reaktionskraft aus der Federkraft zur Klemmung des Verstellgliedes auf dem Zylinder zu verwenden. Die Merkmale der Ansprüche 3 bis 7 dienen ebenfalls diesem Bestreben in zweckmäßiger Ausgestaltung der Anordnung mit Merkmalen nach dem Anspruch 2.The characterizing part of claim 2 contains an advantageous embodiment of the features of the invention with the aim of using components as simple as possible for the transmission of the reaction force from the spring force for clamping the adjusting member on the cylinder. The features of claims 3 to 7 also serve this purpose in a more appropriate manner Configuration of the arrangement with features according to claim 2.

Eine weitere Verbesserung der Lösung der erfindungsgemäßen Aufgabe wird nach einem besonderen Erfindungsgedanken mit einer Vorrichtung erreicht, bei der das axial gegenüber dem Zylinder der Wendeeinrichtung verschiebbare Stellglied zur Umstellung der Greifersteuerung mittels eines verdrehbaren Exzenters verstellbar ist, dessen Exzenterbolzen in dem einen Teil und dessen Exzenterzapfen in dem anderen Teil geführt ist, wenn diese Ausbildung mit Merkmalen des Anspruches 8 weitergebildet wird.A further improvement of the solution of the object according to the invention is achieved according to a particular inventive concept with a device in which the actuator which is axially displaceable relative to the cylinder of the turning device can be adjusted by means of a rotatable eccentric for converting the gripper control, the eccentric pin in one part and the eccentric pin in the other part is performed if this training is developed with features of claim 8.

Auf diese Weise wird ermöglicht, daß das Betätigungselement für die Klemmung des Festzahnrades und des Verstellzahnrades zur Drehlagenverstellung und das Betätigungsorgan für die Greiferumstellung unmittelbar nebeneinander an der Maschine angeordnet sind, so daß es für die Greiferumstellung nicht mehr erforderlich ist, auf die Maschine zu steigen und dort die bisher erforderlichen Arbeiten durchzuführen. Darin liegt eine erhebliche Vereinfachung der Maschinenbedienung bei der Umstellung, die auch zu einer merklichen Verringerung der Rüstzeit bei der Umstellung führt.In this way it is possible that the actuating element for clamping the fixed gear and the adjusting gear for rotational position adjustment and the actuating member for the gripper changeover are arranged directly next to one another on the machine, so that it is no longer necessary for the gripper changeover to climb onto the machine and to carry out the work previously required there. This considerably simplifies the machine operation during the changeover, which also leads to a noticeable reduction in the set-up time during the changeover.

Die Ansprüche 9 bis 14 enthalten vorteilhafte Weiterbildungen dieses Erfindungsgedankens im Hinblick auf einfache Bauteile und deren störungsfreie Funktion. Dabei betreffen die Ansprüche 12 und 13 an sich aus der DE-PS 26 20 392 bekannte Mittel zur Sicherung der Endlagen des axial beweglichen Stellgliedes zur Greiferumstellung.Claims 9 to 14 contain advantageous developments of this inventive concept with regard to simple components and their trouble-free function. The claims 12 and 13 relate to means known per se from DE-PS 26 20 392 for securing the end positions of the axially movable actuator for gripper changeover.

Bei dem Ausführungsbeispiel ist ein Festzahnrad 1 an dem einen Ende eines auf der Zeichnung aus Gründen der besseren Übersicht nur teilweise dargestellten Zylinders 2 einer Wendeeinrichtung mittels mehrerer auf dem Umfang verteilt angeordneter Schrauben 3, von denen nur eine gezeichnet ist, befestigt. Das Festzahnrad 1 weist eine im Achsebenenschnitt winkelförmige Ausnehmung auf, die einen Zapfenansatz 4 bildet, auf dem das kranzartige Verstellzahnrad 5 gegenüber dem Festzahnrad 1 im Drehwinkel verstellbar angeordnet ist. Beide Zahnräder 1 und 5 sind durch Klemmung kraftschlüssig miteinander kuppelbar. Dazu ist an der Stirnfläche des Zapfenansatzes 4 mit mehreren Schrauben 6 eine Stützplatte 7 befestigt, gegen die sich mehrere, im Ausführungsbeispiel sechs, Druckhebel 8 abstützen, die sich in einer auf dem Umfang gleichmäßigen Verteilung radial erstrecken. Das eine Ende dieser Druckhebel 8 liegt gegen eine radiale Ringfläche 9 am Verstellzahnrad 5 und das andere Ende gegen eine Scheibe 10 an, die das federbelastete Druckglied bildet, wobei sich die Druckhebel 8 auf der gegenüberliegenden Seite mit Nocken 11 gegen die Stützplatte 7 abstützen. Die Nocken 11 sind zur Erhöhung der Klemmkraft bei geringer Kraftaufwendung nahezu an dem einen Ende der Druckhebel 8, jedoch noch zwischen deren Auflager am Verstellzahnrad und an der Scheibe angeordnet, so daß die Druckhebel 8 Doppelhebel mit ungleich langen Hebelarmen bilden. Die Scheibe 10 ist axial beweglich auf einer Druckstange 12 geführt, die ihrerseits axial beweglich in dem Zylinder 2 parallel zu deren Achse gelagert ist und einen Radialflansch 13 aufweist, der ein Widerlager für eine Druckfeder 14 bildet. Im Beispiel ist eine Säule aus mehreren geschichtet angeordneten Tellerfedern vorgesehen, die sich andererseits gegen die Scheibe 10 abstützen, so daß diese die Druckhebel 8 an den Enden der langen Hebelarme mit der Federkraft aus der Feder 14 und somit von einer Körperkraft unabhängig belastet. Ein Stift 15 greift mit seinen Enden in Bohrungen einerseits im Radialflansch 13 und andererseits in den Zylinder 2 ein und sichert die Druckstange 12 gegen Drehung.In the exemplary embodiment, a fixed gear 1 is attached to one end of a cylinder 2 of a turning device, which is shown only partially in the drawing for reasons of better clarity, by means of a plurality of screws 3 distributed over the circumference, only one of which is shown. The fixed gear 1 has an angular recess in the axial plane section, which forms a pin extension 4, on which the ring-shaped adjusting gear 5 is arranged so as to be adjustable in angle of rotation relative to the fixed gear 1. Both gears 1 and 5 can be non-positively coupled to one another by clamping. For this purpose, a support plate 7 is fastened to the end face of the pin extension 4 with a plurality of screws 6, against which a plurality of, in the exemplary embodiment six, pressure levers 8 are supported, which extend radially in a uniform distribution over the circumference. One end of this pressure lever 8 lies against a radial annular surface 9 on the adjusting gear 5 and the other end against a disc 10, which forms the spring-loaded pressure member, the pressure levers 8 being supported on the opposite side with cams 11 against the support plate 7. The cams 11 are arranged to increase the clamping force with little effort almost at one end of the pressure lever 8, but still between their supports on the adjusting gear and on the disc, so that the pressure levers 8 form double levers with unevenly long lever arms. The disk 10 is guided in an axially movable manner on a pressure rod 12, which in turn is axially movable in the cylinder 2 parallel to its axis and has a radial flange 13 which forms an abutment for a compression spring 14. In the example, a column of several layered disc springs is provided, which are supported on the other hand against the disc 10, so that it loads the pressure lever 8 at the ends of the long lever arms with the spring force from the spring 14 and thus independently of a physical force. A pin 15 engages with its ends in bores on the one hand in the radial flange 13 and on the other hand in the cylinder 2 and secures the push rod 12 against rotation.

An den die Feder 14 durchsetzenden Abschnitt der Druckstange 12 schließt sich im Bereich der Druckhebel 8 ein Druckring 16 mit einem integrierten Wälzlager 17 an, wobei das eine Ende des Druckringes 16 an der Scheibe 10 anliegt und gegen dessen anderes Ende eine Gewindehülse 18 beweglich ist, deren Muttergewinde auf einem Bolzengewinde am freien, nach außen geführten Ende der Druckstange durch ein Betätigungsorgan, zum Beispiel einen Sechskantkopf 19, verschraubt werden kann. Zwischen der Gewindehülse 18 und dem Druckring 16 ist ein Spiel 20 vorgesehen, so daß die Gewindehülse 18 zum Lösen der die Kupplung zwischen dem Festzahnrad 1 und dem Verstellzahnrad 5 bewirkenden Klemmung auf einem ersten Abschnitt um dieses Spiel axial bewegt werden muß, bevor in einem zweiten Abschnitt der Bewegung der Gewindehülse 18 Kräfte auf den Druckring 16 ausgeübt werden können, um diesen mit der Scheibe gegen die Federkraft der Feder 14 zu verschieben und dadurch die Druckhebel 8 zu entlasten. Umgekehrt wird bei Bewegung der Gewindehülse 18 in Gegenrichtung zunächst wieder die volle Federkraft der Feder 14 auf die Druckhebel 8 wirksam, bevor sich die Gewindehülse 18 auf dem Abschnitt des Spiels bewegt. Letztere Bewegung dient zur Betätigung eines im Versorgungsstromkreis der Maschine liegenden Schalters 21. Für dessen Betätigung greift ein bei 22 maschinenfest gelagerter Doppelhebel 23 mit dem einen Ende in eine Ringnut 24 am Umfang der Gewindehülse 18 ein. Das andere Ende wirkt auf das Betätigungsorgan des Schalters 21 und erstreckt sich zwischen einem Anschlag 25 sowie einer Feder 26, so daß der Anschlag 25 die Bewegung der Gewindehülse 18 nach außen, und damit deren Bewegung auf dem das Spiel 20 bestimmenden Abschnitt, begrenzt. Andererseits sorgt die Feder 26 für eine Rückstellung des Doppelhebels 23 in die Anschlaglage, in der der Schalter 21 den Stromkreis der Maschine bei angezogener Klemmung, das heißt, kraftschlüssiger Kupplung der beiden Zahnräder 1 und 5, freigibt. Dadurch wird mit Sicherheit erreicht, daß die Maschine abgeschaltet ist, bevor die Klemmung gelöst werden kann, und erst wieder einschaltbar ist, wenn die Klemmung voll wirksam ist. Dieser Zustand ist in der Figur 1 dargestellt, während die Figur 2 den Zustand der gelösten Klemmung wiedergibt, bei dem die Gewindehülse 18 zunächst um den Weg des Spiels 20 in der Zeichenebene nach rechts verschraubt wurde und dabei den Schalter 21 zur Unterbrechung des Stromkreises im Antrieb der Maschine betätigt hat, bevor der Druckring 16 zur Minderung bzw. Aufhebung der Federkraft auf die Enden der Druckhebel 8 gegen die Scheibe 10 axial verschoben wurde. Zur Begrenzung dieser Bewegung ist der Druckring 16 auf einer Stufe der Druckstange 12 angeordnet, die gegenüber dem die Feder 14 durchsetzenden Teil einen geringeren Durchmesser aufweist, so daß für die Bewegung des Druckringes 16 ein stufenförmiger Anschlag gebildet wird.A pressure ring 16 with an integrated roller bearing 17 adjoins the section of the push rod 12 passing through the spring 14, the one end of the pressure ring 16 abutting the disk 10 and a threaded sleeve 18 being movable against the other end thereof, whose nut thread can be screwed onto a bolt thread at the free, outwardly directed end of the push rod by an actuating element, for example a hexagon head 19. Between the threaded sleeve 18 and the pressure ring 16, a game 20 is provided, so that the threaded sleeve 18 must be moved axially for releasing the clamping effecting the coupling between the fixed gear 1 and the adjusting gear 5 on this play before this in a second Section of the movement the threaded sleeve 18 forces can be exerted on the pressure ring 16 in order to displace it with the disk against the spring force of the spring 14 and thereby relieve the pressure lever 8. Conversely, when the threaded sleeve 18 moves in the opposite direction, the full spring force of the spring 14 is again effective on the pressure lever 8 before the threaded sleeve 18 moves on the portion of the play. The latter movement serves to actuate a switch 21 located in the supply circuit of the machine. For its actuation, a double lever 23, which is fixed to the machine at 22, engages with one end in an annular groove 24 on the circumference of the threaded sleeve 18. The other end acts on the actuating member of the switch 21 and extends between a stop 25 and a spring 26, so that the stop 25 limits the movement of the threaded sleeve 18 to the outside, and thus its movement on the section determining the play 20. On the other hand, the spring 26 provides for a return of the double lever 23 to the stop position, in which the switch 21 releases the circuit of the machine when the clamp is tightened, that is to say the frictional coupling of the two gear wheels 1 and 5. This ensures with certainty that the machine is switched off before the clamping can be released and can only be switched on again when the clamping is fully effective. This state is shown in Figure 1, while Figure 2 shows the state of the released clamping, in which the threaded sleeve 18 was first screwed to the right by the path of the game 20 in the plane of the drawing and the switch 21 to interrupt the circuit in the drive has operated the machine before the pressure ring 16 has been axially displaced against the disk 10 to reduce or cancel the spring force on the ends of the pressure lever 8. To limit this movement, the pressure ring 16 is arranged on a step of the pressure rod 12 which has a smaller diameter than the part passing through the spring 14, so that a step-shaped stop is formed for the movement of the pressure ring 16.

Das dem Bolzengewinde gegenüberliegende, nach innen weisende Ende der Druckstange 12 wirkt gegen einen zweiten, winkelförmig ausgebildeten Druckhebel 27, der in dem Zylinder 2 im Bereich des axial beweglichen Verstellgliedes 28 um einen quer zur Längsachse der Welle 2 angeordneten Gelenkbolzen 29 beweglich ist. Der andere Arm des winkelförmig ausgebildeten Druckhebels 27 untergreift etwa mittig einen Klemmbügel 30, dessen Enden durch je einen Zugbolzen 31 und 32 mit in außenliegenden Ausnehmungen des Verstellgliedes 28 angeordneten Klemmstücken 54 und 55 verbunden sind, die über Unterlegscheiben 33 und 34 gegen die Enden des Klemmbügels 30 wirken. Die Zugbolzen 31 und 32 hintergreifen mit einem Bundkopf den Klemmbügel 30 und sind durch Bohrungen des Klemmbügels 30 und des Verstellgliedes 28 geführt. Die Druckstange 12 überträgt die Federkraft der Feder 14 über den winkelförmigen Druckhebel 27 auf den Klemmbügel 30, so daß die Federkraft über die Zugbolzen 31 und 32 als Klemmkraft auf die Klemmstücke 54 und 55 wirkt und das Verstellglied 28 gegen an dem Zylinder 2 ausgebildete Sitzflächen preßt. Zur Erzielung gleichmäßiger Klemmkräfte in den beiden Klemmstücken 54 und 55 berühren sich der eine Arm des Druckhebels 27 und der Klemmbügel 30 mit balligen Flächen, die gegebenenfalls durch Druckscheiben aus einem verschleißfesten Werkstoff gebildet sein können. Die Klemmstücke 54 und 55 sind auf den freien Enden der Zugbolzen 31 und 32 verschraubbar, um eine Einstellung der Klemmkräfte und eines Spiels 35 zwischen der Druckstange 12 und den Übertragungsgliedern zu ermöglichen und um sicherzustellen, daß das Verstellglied 28 axial beweglich ist, wenn die Feder 14 zur Minderung bzw. Aufhebung der auf die Druckhebel 8 wirksamen Federkraft zusammengedrückt ist, wobei sich die Druckstange 12 in der Zeichnung nach links verschiebt, bis der Druckring 16 die Anschlagschulter der Druckstange 12 berührt. Das Spiel 35 zwischen der Druckstange 12 und den Zwischengliedern der Klemmung des axial beweglichen Verstellgliedes 28 ist also sichtbar, wenn die Klemmung gelöst ist. Im Gegensatz dazu ist das Spiel 20 zwischen der Gewindehülse 18 und dem Druckring 16 sichtbar, wenn die Klemmung angezogen ist.The inward-facing end of the pressure rod 12 opposite the bolt thread acts against a second, angularly shaped pressure lever 27 which is movable in the cylinder 2 in the region of the axially movable adjusting member 28 about an articulated bolt 29 arranged transversely to the longitudinal axis of the shaft 2. The other arm of the angular pressure lever 27 engages approximately centrally under a clamping bracket 30, the ends of which are each connected by a tension bolt 31 and 32 to clamping pieces 54 and 55 arranged in external recesses of the adjusting member 28, which are connected to the ends of the clamping bracket via washers 33 and 34 30 act. The tension bolts 31 and 32 engage behind the clamping bracket 30 with a collar head and are guided through bores in the clamping bracket 30 and the adjusting member 28. The push rod 12 transmits the spring force of the spring 14 via the angular pressure lever 27 to the clamping bracket 30, so that the spring force acts via the tension bolts 31 and 32 as a clamping force on the clamping pieces 54 and 55 and presses the adjusting member 28 against seat surfaces formed on the cylinder 2 . In order to achieve uniform clamping forces in the two clamping pieces 54 and 55, one arm of the pressure lever 27 and the clamping bracket 30 touch with spherical surfaces, which can optionally be formed by pressure disks made of a wear-resistant material. The clamping pieces 54 and 55 can be screwed onto the free ends of the tension bolts 31 and 32 to allow adjustment of the clamping forces and a play 35 between the push rod 12 and the transmission members and to ensure that the adjustment member 28 is axially movable when the spring 14 is compressed to reduce or cancel the spring force acting on the pressure lever 8, the pressure rod 12 in the Drawing moves to the left until the pressure ring 16 touches the stop shoulder of the push rod 12. The play 35 between the push rod 12 and the intermediate members of the clamping of the axially movable adjusting member 28 is therefore visible when the clamping is released. In contrast, the game 20 between the threaded sleeve 18 and the pressure ring 16 is visible when the clamp is tightened.

Das axial bewegliche Verstellglied 28 zur Greiferumstellung ist als ein sich über die Breite der Maschine erstreckender Schlitten ausgebildet und in einer Ausnehmung des Zylinders 2 an durch Schrauben 36 und 37 einstellbaren Führungsleisten 38 und 39 auf der Antriebsseite und auf der Bedienungsseite geführt. Eine Klemmung des Verstellgliedes 28 auf nur einer Seite ist dadurch ausreichend.The axially movable adjustment member 28 for gripper changeover is designed as a slide that extends across the width of the machine and is guided in a recess in the cylinder 2 on guide strips 38 and 39 that can be adjusted by screws 36 and 37 on the drive side and on the operating side. A clamping of the adjusting member 28 on only one side is therefore sufficient.

Zur axialen Verstellung des Verstellgliedes 28 für die Greiferumsteuerung ist eine Exzentermechanik aus einem im Gegensatz zu bekannten Ausbildungen in dem Zylinder 2 um einen quer zu deren Achse gelagerten Exzenterbolzen 40 und einem in ein Lager 56 des Verstellgliedes 28 eingreifenden Exzenterzapfen 41 vorgesehen. Das Lager 56 besteht zum Beispiel aus einer Schaltplatte eines verschleißfesten Werstoffes. Die Verstellung des Exzenterbolzens 40 erfolgt über ein ebenfalls in dem Zylinder 2 gelagertes Winkelgetriebe aus den beiden Kegelzahnrädern 42 und 43 über eine Schaltwelle 44, die parallel zur Achse des Zylinders 2 in diesem verdrehbar gelagert ist. Auf dem inneren Ende der Schaltwelle 44 ist das Kegelrad 42 befestigt. Das andere Ende der Schaltwelle ist durch die Stützplatte 7 nach außen geführt und trägt dort ein Betätigungsorgan, welches neben der Klemmung für das Verstellzahnrad mit dem Festzahnrad angeordnet ist. Dadurch kann die Verstellung des Verstellgliedes 28 etwa an der gleichen Stelle erfolgen, an der auch die die kraftschlüssige Kupplung der beiden Zahnräder 1 und 5 sowie des Verstellgliedes 28 mit dem Zylinder 2 bewirkende Klemmung vorgesehen ist. Die Kombination der Absicherung der Klemmung zwischen dem Festzahnrad 1 und dem Verstellzahnrad 5 mit einer Klemmung zwischen dem Verstellglied 28 und dem Zylinder 2 ermöglicht eine Axialverstellung jedoch erst nach dem Lösen dieser Klemmung. Eine Endlagensicherung durch elektrische Schaltmittel in an sich bekannter Weise bleibt hiervon unberührt. Für die axiale Bewegung des Verstellgliedes 28 ist auf der Schaltwelle 44 ein Sechskantkopf 45 für einen Steckschlüssel vorgesehen, mit dem die Verschiebung des Verstellgliedes 28 von der einen in die andere Endlage erfolgt. Dieser Steckschlüssel 46 besitzt entsprechend der zeichnerischen Darstellung in den Figuren 5 und 6 eine Ausbildung, die das Aufstecken und das Abziehen des Steckschlüssels von dem als Betätigungsorgan wirksamen Sechskantkopf 45 auf der Schaltwelle 44 ausschließlich in den eingestellten Endlagen des Verstellgliedes 28 ermöglicht. Dazu weist der Steckschlüssel in einer an sich bekannten Weise an zwei sich diametral gegenüberliegenden Seiten zwei zueinander parallele Abflachungen 47 und 48 an einem Flanschrand 49 auf, der eine Sicherungsplatte 50 hintergreift, die an der Stützscheibe 7 befestigt ist. Die Figur 6 zeigt eine Stellung des Steckschlüssels, in der ein Abziehen von dem Sechskantkopf 45 möglich ist, und die einer Endlage des Verstellgliedes 28 entspricht. Die Figur 5 zeigt eine beliebige Zwischenstellung, in der der Flanschrand 49 die Sicherungsplatte 50 hintergreift, so daß der Steckschlüssel 46 nicht von dem Sechskant 45 auf der Schaltwelle 44 abgezogen kann. Zur Markierung der Endlagen weist der Sechskant 45 an seiner Vorderseite eine Marke 51 auf, während an der Sicherungsplatte 50 unterschiedliche Symbole 52 und 53 für Schöndruck sowie für Schön- und Widerdruck angebracht sind, deren jeweils zugehörige Endlage des Verstellgliedes 28 die Marke 51 in Verbindung mit dem entsprechenden Symbol anzeigt.

The bearing 56 consists, for example, of a circuit board made of a wear-resistant material. The eccentric bolt 40 is adjusted via an angular gear, likewise mounted in the cylinder 2, from the two bevel gears 42 and 43 via a selector shaft 44, which is rotatably mounted parallel to the axis of the cylinder 2 in the latter. The bevel gear 42 is attached to the inner end of the selector shaft 44. The other end of the selector shaft is guided through the support plate 7 to the outside and carries an actuating member there, which is arranged next to the clamp for the adjusting gear with the fixed gear. As a result, the adjustment of the adjusting member 28 can take place approximately at the same point at which the non-positive coupling of the two also occurs Gears 1 and 5 and the adjusting member 28 with the cylinder 2 causing clamping is provided. The combination of securing the clamping between the fixed gear 1 and the adjusting gear 5 with a clamping between the adjusting member 28 and the cylinder 2, however, allows an axial adjustment only after this clamping has been released. End position protection by electrical switching means in a manner known per se remains unaffected by this. For the axial movement of the adjusting member 28, a hexagon head 45 for a socket wrench is provided on the control shaft 44, with which the adjusting member 28 is displaced from one end position to the other. 5 and 6, this socket wrench 46 has a design which enables the socket wrench to be inserted and removed from the hexagon head 45 acting as an actuating element on the control shaft 44 only in the set end positions of the adjusting member 28. For this purpose, the socket wrench has in a manner known per se on two diametrically opposite sides two flats 47 and 48 which are parallel to one another on a flange edge 49 which engages behind a securing plate 50 which is fastened to the support disk 7. FIG. 6 shows a position of the socket wrench in which removal from the hexagon head 45 is possible and which corresponds to an end position of the adjusting member 28. FIG. 5 shows any intermediate position in which the flange edge 49 engages behind the securing plate 50 so that the socket wrench 46 cannot be removed from the hexagon 45 on the selector shaft 44. To mark the end positions, the hexagon 45 has a mark 51 on its front, while different symbols 52 and 53 for face printing as well as for face and reverse printing are attached to the securing plate 50, the respectively associated end position of the adjusting member 28 the mark 51 in connection with the corresponding symbol.
