Description

Die vorliegende Erfindung betrifft im allgemeinen Positionsregler für Umdrehungseinstellungen und im besonderen Positionsregler für das Einstellen der Position einer Farbauftragwalze in einer Druckmaschine.The present invention relates generally to position controllers for Rotation settings and in particular position controller for setting the Position of an inking roller in a printing press.

Die in Fig. 1 gezeigte und nachfolgend beschriebene Druckmaschine des Standes der Technik umfaßt einen gattungsbildenden Stellmechanismus für eine einstellbare Steuerkurve, um Einstellungen einer Farbauftragwalze vorzunehmen. Zum Einstellen der Position der Steuerkurve kann eine hexagonale Stellstange mit einem hexagonalen Querschnitt an einem Ende und einem Zahnrad am anderen Ende verwendet werden. Wenn die hexagonale Stellstange gedreht wird, dreht das Zahnrad eine Welle, auf der eine einstellbare Komponente angebracht ist. Aufgrund eines internen Gewindes der Steuerkurve und der Tatsache, daß sich die Steuerkurve nicht drehen kann, verursacht das Drehen der Welle eine Verschiebung der Steuerkurve. Eine Druckfeder wirkt der Bewegung der Steuerkurve entgegen, so daß sich die verschiedenen Komponenten des Stellmechanismus nicht bewegen können, ohne daß ein ausreichendes Drehmoment an der hexagonalen Stellstange anliegt. Somit kann die hexagonale Stellstange für das Einstellen einer einstellbaren Komponente in einer Druckmaschine verwendet werden.The printing machine of the prior art shown in FIG. 1 and described below Technology includes a generic actuator mechanism for an adjustable cam to Make settings of an inking roller. To adjust the position of the Control cam can be a hexagonal actuator rod with a hexagonal cross section one end and a gear on the other end. If the hexagonal control rod is rotated, the gear rotates a shaft on which one adjustable component is attached. Due to an internal thread of the Control curve and the fact that the control curve cannot rotate rotating the shaft will shift the cam. A compression spring acts Movement of the control curve opposite, so that the various components of the Adjustment mechanism can not move without sufficient torque of the hexagonal control rod. Thus, the hexagonal control rod for the Setting an adjustable component can be used in a printing press.

Jedoch funktioniert die sich an der Steuerkurve befindliche Druckfeder bekanntermaßen nicht störungsfrei oder ist nach einer Zeit abgenutzt und liefert auch nicht genügend Widerstand, obschon sie dennoch eine Einstellung der hexagonalen Stellstange erlaubt.However, the compression spring on the control cam is known to work not trouble-free or is worn out after a while and does not deliver enough Resistance, although it still allows adjustment of the hexagonal control rod.

Die vorliegende Erfindung gemäß Anspruch 1 sieht einen Positionsregler vor, der eine Stellstange umfaßt, die ein erstes Ende mit mindestens drei flachen Seiten, ein zweites Ende, eine mit dem zweiten Ende verbundene einstellbare Komponente, die durch die Umdrehung der Stellstange eingestellt werden kann, und einen ersten und einen zweiten Satz von Blattfedern aufweist, wobei der erste Satz von Blattfedern mit einer ersten und der zweite Satz von Blattfedern mit einer zweiten der mindestens drei flachen Seiten der Stellstange zusammenwirken.The present invention according to claim 1 provides a position controller comprising an actuating rod, which has a first end with at least three flat sides, a second end, one with the adjustable component connected by the rotation of the second end Adjustment rod can be adjusted, and a first and a second set of Has leaf springs, the first set of leaf springs having a first and the second Set of leaf springs with a second of the at least three flat sides of the actuating rod interact.

Somit wird durch die Blattfedern ein entgegengesetzt wirkendes Drehmoment für die verschiedenen Komponenten des Positionsreglers erzeugt.Thus, the leaf springs create an opposing torque for the various components of the position controller.

Vorzugsweise besitzt das erste Ende der Stellstange sechs flache Seiten, d. h. es ist hexagonal geformt. Der erste Blattfedersatz wirkt auf die erste der hexagonalen Seiten und der zweite Blattfedersatz wirkt vorzugsweise auf die zweite der hexagonalen Seiten, wobei die zweite Seite direkt gegenüber der ersten Seite liegt. Bei dieser Anordnung ist es ebenfalls vorteilhaft, wenn sich der erste Blattfedersatz parallel zum zweiten Satz befindet.Preferably the first end of the actuating rod has six flat sides, i. H. it is hexagonal shaped. The first set of leaf springs acts on the first of the hexagonal sides and the second set of leaf springs preferably acts on the second of the hexagonal sides, with the second side directly opposite the first side. With this arrangement it is also advantageous if the first set of leaf springs is parallel to the second set located.

Jeder Blattfedersatz kann eine einzige oder vorzugsweise eine Vielzahl von Blattfedern umfassen. Das durch die Blattfedern an der Stellstange erzeugte Gegendrehmoment kann durch Ändern der Eigenschaften, der Anzahl und/oder der Dicke der Blattfedern mühelos variiert werden, jedoch ein Gegendrehmoment von 10 bis 15 inches x lb (etwa 1,130 bis 1,695 N x m) ist für eine normale Farbwalzenlagerung in einer Druckmaschine ein bevorzugter Wert.Each set of leaf springs can be a single or preferably a plurality of leaf springs include. The counter torque generated by the leaf springs on the adjusting rod can effortlessly by changing the properties, number and / or thickness of the leaf springs can be varied, but a back torque of 10 to 15 inches x lb (about 1,130 to 1,695 N x m) is for one normal ink roller storage in a printing machine is a preferred value.

Die vorliegende Erfindung erzeugt in vorteilhafter Weise für die Umdrehungen der Stellstange, sowohl im Uhrzeigersinn als auch im Gegenzeigersinn, ein gleiches Gegendrehmoment. Die von den Blattfedersätzen erzeugte Haltekraft oder Gegenkraft wirkt über einen großen Oberflächenbereich, was den Verschleiß der Oberfläche minimiert. Es sind keine speziellen Einstellungen erforderlich. Reibung, wie sie bei einem Gewindeverhältnis entsteht, wird hier zur Erzeugung von Widerstand nicht eingesetzt, so daß das Trennen von Gewinden kein Problem darstellt. Die vorliegende Erfindung erlaubt eine kompakte Konstruktion und läßt es auch zu, daß die Stellstange sich axial bewegt oder in eine dritte Richtung "schwebt", während sie immer noch ein Drehmomentwiderstand in die beiden anderen Richtungen bietet. The present invention advantageously generates for the revolutions of the Control rod, both clockwise and counter-clockwise, the same Counter torque. The holding force or counterforce generated by the leaf spring sets acts across a large surface area, causing surface wear minimized. No special settings are required. Friction, as with a thread ratio arises, is not used here to generate resistance used, so that the separation of threads is not a problem. The present Invention allows a compact construction and also allows the control rod moves axially or "floats" in a third direction while still a Offers torque resistance in the other two directions.

Über den Blattfedern kann eine Abdeckung vorgesehen sein, um Verunreinigungen zu verhindern oder zu minimieren. Die Abdeckung kann entweder das erste Ende bedecken, oder das erste Ende kann aus einer Öffnung in der Abdeckung herausragen.A cover can be provided over the leaf springs to prevent contamination prevent or minimize. The cover can either cover the first end, or the first end may protrude from an opening in the cover.

Die vorliegende Erfindung wird in vorteilhafter Weise für das Einstellen von Walzen in einer Druckmaschine und speziell für das Einstellen der Position einer Farbauftragwalze angewandt. Somit ist die einstellbare Komponente vorzugsweise eine Steuerkurve für das Einstellen einer Farbauftragwalze.The present invention is used advantageously for setting rollers in a printing machine and especially for adjusting the position of an inking roller applied. Thus, the adjustable component is preferably a control curve for the Setting an inking roller.

Fig. 1 zeigt einen herkömmlichen Positionsregler 10, der in einer Druckmaschine 1 verwendet wird. Der Positionsregler 10 umfaßt eine hexagonale Stellstange 12 mit einem hexagonalen Querschnitt an dem einen Ende 14 und einem Zahnrad 16 an dem anderen Ende 18. Die Stellstange 12 wird für das Einstellen der Position einer einstellbaren Komponente 20 in der Druckmaschine 1 verwendet. Die einstellbare Komponente 20 kann z. B. eine Steuerkurve zum Einstellen der Position einer Farbauftragwalze sein.1 shows a conventional position controller 10 which is used in a printing press 1 is used. The position controller 10 comprises a hexagonal adjusting rod 12 with a hexagonal cross section at one end 14 and a gear 16 at the other End 18. The actuator rod 12 is used for adjusting the position of an adjustable Component 20 used in the printing press 1. The adjustable component 20 can e.g. B. be a control curve for adjusting the position of an inking roller.

Die ein internes Gewinde aufweisende einstellbare Komponente 20 ist auf einer ebenfalls mit einem Gewinde versehenen Welle 22 angebracht und somit durch die Gewinde mit dieser verbunden. Die Welle 22 wird von Armen 21 gestützt und ein Ende der Welle ist als ein (zweites) Zahnrad 26 ausgebildet, das mit dem Zahnrad 16 der hexagonalen Stellstange 12 zusammenwirkt. Eine Seite der einstellbaren Komponente 20 steht in Wechselwirkung mit einem Gehäuseabschnitt 30 der Druckmaschine, um ein Drehen der einstellbaren Komponente 20 zu verhindern, jedoch eine Verschiebung entlang der Welle 22 zuzulassen. Der Gehäuseabschnitt 30 stützt auch die von den Armen 21 gehaltene Welle 22 in drehbarer Weise.The adjustable component 20 having an internal thread is also on one attached with a threaded shaft 22 and thus by the thread with this connected. The shaft 22 is supported by arms 21 and is one end of the shaft formed as a (second) gear 26, which with the gear 16 of the hexagonal actuating rod 12th interacts. One side of the adjustable component 20 interacts with a housing section 30 of the printing press to rotate the adjustable To prevent component 20, but a displacement along the shaft 22 permit. The housing section 30 also supports the one held by the arms 21 Shaft 22 in a rotatable manner.

Wenn die hexagonale Stellstange 12 gedreht wird, dreht das Zahnrad 16 das (zweite) Zahnrad 26 und damit die Welle 22, auf der sich die einstellbare Komponente 20 in Gewindeverbindung befindet. Aufgrund des internen Gewindes der Komponente 20 und der Tatsache, daß sich die Komponente 20 nicht drehen kann, verursacht das Drehen der Welle eine Verschiebung der Komponente 20 entlang der Achse der Welle 22. Eine Druckfeder 24 liefert Widerstand gegen die Bewegung der Komponente 20, so daß sich die verschiedenen Komponenten des Stellmechanismus ohne genügendes Drehmoment an der hexagonalen Stellstange 12 nicht bewegen können.When the hexagonal actuator rod 12 is rotated, the gear 16 rotates the (second) gear 26 and thus the shaft 22 on which the adjustable component 20 is located Threaded connection is located. Due to the internal thread of component 20 and the fact that component 20 cannot rotate causes rotation of the Shaft a displacement of component 20 along the axis of shaft 22. a Compression spring 24 provides resistance to the movement of component 20 so that the various components of the adjusting mechanism without sufficient torque the hexagonal control rod 12 can not move.

Fig. 2 zeigt einen Positionsregler 40 gemäß einer Ausführungsform der vorliegenden Erfindung mit einer hexagonalen Stellstange 42, einem ersten Blattfedersatz 46 und einem zweiten Blattfedersatz 48. Die hexagonale Stellstange 42 besitzt ein erstes Ende 43 mit sechs flachen Seiten, die eine erste Seite 44 und eine gegenüberliegende zweite Seite 45 einschließen. Wie in Fig. 2 dargestellt ist, steht der erste Blattfedersatz 46 in Wechselwirkung mit der ersten flachen Seite 44, und der zweite Blattfedersatz 48 steht in Wechselwirkung mit der zweiten flachen Seite 45 (jedoch ändern sich diese Seiten mit der Umdrehung der Stellstange 42). 2 shows a position controller 40 according to an embodiment of the present Invention with a hexagonal adjusting rod 42, a first leaf spring set 46 and a second leaf spring set 48. The hexagonal adjusting rod 42 has a first end 43 with six flat sides, a first side 44 and an opposite second Include page 45. As shown in FIG. 2, the first leaf spring set 46 is in Interaction with the first flat side 44, and the second leaf spring set 48 is in Interaction with the second flat side 45 (however, these sides change with the rotation of the control rod 42).

Jeder Blattfedersatz 46, 48 weist eine Vielzahl von Blattfedern auf, wobei jede Blattfeder eine gewisse Dicke hat und aus einer flachen, dünnen, vorzugsweise rechteckigen Metallplatte besteht, die einen bestimmten Federwiderstand oder Federkonstante aufweist. Jede flache, dünne Platte ist an ihrem einen Ende mit einem Loch versehen(nicht gezeigt), in das ein Befestigungselement eingepaßt wird, um die Blattfeder auf ihrem Platz zu halten. Dem ersten Blattfedersatz 46 ist ein Befestigungselement 47, z. B. eine Schraube oder Mutter-Schraube-Kombination zugeordnet und dem zweiten Blattfedersatz 48 ist gleichermaßen ein Befestigungselement 49 zugeordnet. Mit den Befestigungselementen der vorliegenden Erfindung ist es möglich, die Federkonstante aller Blattfedern der Sätze 46 und 48 schnell und mühelos einzustellen, indem individuelle Blattfedern hinzugefügt oder entfernt werden. Die Befestigungselemente 47, 49 können die Sätze der Blattfedern mit einem Gehäuse 3 verbinden.Each leaf spring set 46, 48 has a plurality of leaf springs, each leaf spring has a certain thickness and a flat, thin, preferably rectangular Metal plate is made up of a certain spring resistance or spring constant having. Each flat, thin plate has a hole at one end provided (not shown) into which a fastener is fitted around the leaf spring to keep in place. The first leaf spring set 46 is a fastening element 47, z. B. assigned a screw or nut-screw combination and the second Leaf spring set 48 is also associated with a fastener 49. With the Fasteners of the present invention make it possible to adjust the spring constant of all leaf springs of sets 46 and 48 can be adjusted quickly and easily by individual leaf springs can be added or removed. The fasteners 47, 49 can connect the sets of leaf springs to a housing 3.

In der Ausführungsform der Fig. 2 sind die Sätze der Blattfedern 46, 48 in vorteilhafter Weise parallel zueinander angeordnet, obschon sie sich auf den jeweils gegenüberliegenden Seiten der hexagonalen Stellstange 42 befinden. Es versteht sich von selbst, daß die Blattfedern mit der hexagonalen Stellstange 42 zusammenwirken, um einen Widerstand gegen die Umdrehung der Stellstange 42 zu erzeugen. Somit verhindert der Positionsregler 40 der vorliegenden Erfindung ein unerwünschtes Drehen der Stellstange 42 oder anderer verbundener Komponenten.In the embodiment of FIG. 2, the sets of leaf springs 46, 48 are more advantageous Arranged parallel to each other, although they relate to each opposite sides of the hexagonal adjusting rod 42 are located. It goes without saying itself that the leaf springs interact with the hexagonal adjusting rod 42 in order to to create a resistance to the rotation of the actuating rod 42. Thus prevented position controller 40 of the present invention undesirably rotates the Actuator rod 42 or other connected components.

Es ist zu bemerken, daß sich die Sätze der Blattfedern 46 und 48 axial entfernt von dem Ende der hexagonalen Stellstange 42 befinden, wie dies bei der in Fig. 5 gezeigten Ausführungsform der Fall ist.It should be noted that the sets of leaf springs 46 and 48 are axially distant from that End of the hexagonal actuator rod 42 are, as in the shown in Fig. 5 Embodiment is the case.

Die Blattfedersätze 66 und 68 erstrecken sich parallel zueinander und sind mittels eines gemeinsamen Befestigungselements 64 auf einer Befestigungsplatte 65 befestigt.4 shows a position controller 60 according to a further embodiment of the present invention, in which a first leaf spring set 66 with a flat surface a hexagonal adjusting rod 62 and a second leaf spring set 68 with one opposite flat surface of the hexagonal actuator rod 62 in interaction stand for the free movement of the hexagonal actuating rod 62 and that with the Restrict position controller 60 connected components. The leaf spring sets 66 and 68 extend parallel to one another and are common to one another Fastener 64 attached to a mounting plate 65.

Fig. 5 ist eine teilweise Seitenansicht der Ausführungsform der Fig. 4, aus dem klar hervorgeht, daß die Blattfedersätze 66 und 68 um einen Abstand D axial von dem Kopfende 61 der Stellstange 62 abgesetzt sind. Es können auf jeder axialen Seite der Blattfedersätze 66 und 68 Sicherungsringe 70, 71 vorgesehen sein, um ein Drehen der Blattfedern um das Befestigungselement 64 zu verhindern. Das zweite oder hintere Ende 78 der Stellstange 62 kann ein Zahnrad aufweisen, das mit einer einstellbaren Komponente zusammenwirkt, wie dies in Fig. 1 gezeigt ist. Eine an dem Gehäuseabschnitt befestigte Abdeckung kann die Blattfedersätze 66 und 68 teilweise oder vollständig bedecken, um Schutz zu bieten.Fig. 5 is a partial side view of the embodiment of Fig. 4, from which clear shows that the leaf spring sets 66 and 68 by a distance D axially from the Head end 61 of the actuating rod 62 are offset.

Die Fig. 6a, 6B und 6C zeigen die verschiedenen Durchfederungspositionen der Blattfedersätze 66 und 68 der Ausführungsform der Fig. 4, während die Stellstange 62 gedreht wird. Fig. 6A zeigt die Stellstange 62 in einer Ruhestellung, Fig. 6B zeigt eine vorübergehende Durchfederungsposition, die die Blattfedersätze 66 und 68 beim Beginn der Umdrehung der Stellstange 62 einnehmen, und Fig. 6C zeigt eine maximale Durchfederungsposition der Blattfedersätze 66 und 68, bevor die Stellstange 62 eine neue Ruhestellung erreicht, während diese in die gleiche Richtung weiter gedreht wird. Das durch die Blattfedersätze erzeugte Gegendrehmoment kann durch die Anzahl, Dicke oder Art der verwendeten Blattfedern auf einfache Weise variiert werden, jedoch ist es vorteilhaft, die gleiche Anzahl von Federn für jeden Blattfedersatz zu verwenden. 6a, 6B and 6C show the different deflection positions of the Leaf spring sets 66 and 68 of the embodiment of FIG. 4, while the actuating rod 62nd is rotated. FIG. 6A shows the actuating rod 62 in a rest position, FIG. 6B shows one temporary deflection position that the leaf spring sets 66 and 68 at the start the rotation of the actuator rod 62, and Fig. 6C shows a maximum Deflection position of the leaf spring sets 66 and 68 before the actuating rod 62 a new one Rest position reached while this is rotated further in the same direction. The Counter torque generated by the leaf spring sets can be determined by the number, thickness or The type of leaf springs used can be varied in a simple manner, however it is advantageous to use the same number of springs for each leaf spring set.
