Description

Die Erfindung betrifft eine Vorrichtung zum zyklischen Heben und Senken eines Hubsaugers im Anleger einer Bogenverarbeitungsmaschine mit Mitteln zur Einstellung der Ansaughöhe.The invention relates to a device for cyclic lifting and lowering a suction cup in the feeder Sheet processing machine with means for adjusting the Suction height.

Durch die DE 976 134 C, die dem Oberbegriff des Anspruchs 1 entspricht, ist es bekannt, an einem Hubsaugergetriebe Stellmittel vorzusehen, die es ermöglichen, daß ein zwischen einer oberen Bogenseite und einem Hubsauger in Ansaugposition vorgesehener Abstand einstellbar ist. Insbesondere bei der Verarbeitung von Druckstoffen verschiedener Dicke, z. B. Florpostpapier bis zu Karton, muß die Ansaughöhe einstellbar sein. Bei Werkdruckpapier und Florpostpapier muß der Abstand relativ groß sein, damit ein Durchsaugen und Ansaugen von Doppelbogen verhindert wird. Bei schwerem Karton muß der Abstand relativ klein sein, damit die Ansaugkraft groß genug ist, um den Karton sicher anzusaugen.From DE 976 134 C, which corresponds to the preamble of claim 1, it is known to one Hoist suction gear to provide actuating means that make it possible that one between an upper sheet side and a suction cup the distance provided in the suction position is adjustable. Especially when processing printing materials different thickness, e.g. B. pile paper up to cardboard, must the suction height can be adjustable. For printing paper and Florpostpapier the distance must be relatively large in order for a Suction and suction of double sheets is prevented. At heavy cardboard, the distance must be relatively small so that the Suction force is large enough to safely suck the cardboard.

Bei der DE 976 134 C ist zur Einstellung des Abstandes zwischen Bogenstapel und Hubsauger ein Hubsaugergetriebe vorgesehen, bei dem ein Winkel zwischen einem Rollenhebel und einem Betätigungshebel mittels einer Exzenterverstelleinrichtung veränderbar ist.DE 976 134 C is used to adjust the distance between the sheet stack and the suction cup, a suction cup gear provided at an angle between a roller lever and an operating lever by means of a Eccentric adjustment device is changeable.

Es ist bei der Vorrichtung nach der DE 976 134 C von Nachteil, daß mit einer Veränderung der Ansaughöhe auch eine übergabeposition von Hubsauger zu einem nachgeordneten Schleppsauger verändert wird. Diese Maßnahme kann zu Transport- bzw. übergabeproblemen führen, wenn Hubsauger und Schleppsauger nahe beieinander angeordnet sind.It is in the device according to DE 976 134 C of Disadvantage that with a change in the suction height also Transfer position from the suction cup to a downstream one Drag vacuum is changed. This measure can too Transport or handover problems lead when lifting vacuum and Drag vacuums are arranged close together.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Hubsaugerantrieb dergestalt auszubilden, daß eine Ansaugposition des Hubsaugers ohne Veränderung einer übergabeposition stufenlos einstellbar ist.The invention is therefore based on the object Vacuum cleaner drive form such that a Suction position of the vacuum cleaner without changing one transfer position is infinitely adjustable.

Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The object is achieved by the characterizing Features of claim 1 solved.

Der Vorteil der Erfindung liegt insbesondere darin, daß ein von dem Hubsauger vereinzelter, vom Bogenstapel angehobener Bogen sicher an den Schleppsauger übergeben werden kann.The advantage of the invention is in particular that a separated by the suction device, raised by the sheet stack Bow can be safely handed over to the vacuum cleaner.

Ein weiterer Vorteil ist die stationäre Anordnung des Einstellmittels. Durch diese Maßnahme ist es möglich, den Abstand des Hubsaugers zur Oberseite des Bogens auch während des Betriebes einzustellen.Another advantage is the stationary arrangement of the Adjusting means. This measure makes it possible to Distance of the suction cup to the top of the sheet also during to cease operations.

In vorteilhafter Weise ist es vorgesehen, einen Gelenkpunkt einer den Hub des Hubsaugers verursachenden Koppel auf verschiedene Bewegungsbahnen auszulenken, indem der Gelenkpunkt mittelbar am Einstellmittel gelagert ist.An articulation point is advantageously provided a coupling causing the stroke of the vacuum cleaner deflect different trajectories by the The hinge point is mounted indirectly on the adjusting means.

In weiterer Ausgestaltung ist es vorgesehen, daß ein Führungselement, z. B. Führungsschiene, für den Gelenkpunkt vorgesehen ist, wobei die Führungsschiene mittels eines Einstellmittels um einen gestellfesten Lagerpunkt schwenkbar angeordnet ist. Der Lagerpunkt kennzeichnet gleichzeitig den "übergabepunkt".In a further embodiment it is provided that a Guide element, e.g. B. guide rail, for the hinge point is provided, the guide rail by means of a Adjustment means can be pivoted about a bearing point fixed to the frame is arranged. The bearing point also marks the "transfer point".

Ein erstes Ende des Rollenhebels 9 ist schwenkbar auf einer Achse 11 gelagert, die am Gehäuse 1 befestigt ist. An einem zweiten Ende des Rollenhebels 9 ist mit einem ersten Ende eine nach unten gerichtete Koppel 12 angelenkt. An ein zweites Ende der Koppel 12 ist mittels eines Bolzens 13 je eine weitere Koppel 14 und Koppel 16 mittels eines ersten Endes angelenkt. Die Koppeln 12,14 und 16 sind unabhängig voneinander um den Bolzen 13 verschwenkbar gelagert. Die Koppel 16 ist horizontal angeordnet und mit ihrem zweiten Ende mit einem etwa parallel zur Koppel 16 angeordneten Arm 17 eines zweiarmigen Stellhebels 18 gelenkig an einem Anlenkpunkt 20 verbunden. Der zweite Arm 19 des Stellhebels 18 ist in einem rechten Winkel zum ersten Arm 17 angeordnet. Im Schnittpunkt der Arme 17,19 ist der Stellhebel 18 schwenkbar auf einer Achse 21 gelagert, die am Gehäuse 1 befestigt ist. An einem Ende des nach oben gerichteten Arms 19 greift gelenkig eine im wesentlichen axial bewegbare Stellwelle 22 an. Die Stellwelle 22 ist mittels einer Gewindeverbindung (nicht dargestellt) am Gehäuse 1 drehbar gelagert. Am Ende der Stellwelle 22 ist außerhalb des Gehäuses 1 ein Stellknopf 23 angeordnet. Eine Markierung 24 am Stellknopf 23 dient als optische Anzeige eines Einstellmaßes, gekennzeichnet durch eine an der Außenwand des Gehäuses 1 angebrachten Skala 26.A first end of the roller lever 9 is pivotable on one Axis 11 mounted, which is attached to the housing 1. On one second end of the roller lever 9 is with a first end a coupling 12 directed downwards. On a second end of the coupling 12 is by means of a bolt 13 each a further coupling 14 and coupling 16 by means of a first Articulated in the end. The couplers 12, 14 and 16 are independent pivoted from each other about the bolt 13. The Coupling 16 is arranged horizontally and with its second End with an approximately parallel to the coupling 16 Arm 17 of a two-armed lever 18 articulated on one Articulation point 20 connected. The second arm 19 of the The control lever 18 is at a right angle to the first arm 17 arranged. At the intersection of the arms 17, 19 is the Adjusting lever 18 pivotally mounted on an axis 21 which on Housing 1 is attached. At one end of the top directed arms 19 hinges one essentially axially movable control shaft 22. The adjusting shaft 22 is by means of a threaded connection (not shown) on Housing 1 rotatably mounted. At the end of the control shaft 22 is An adjusting knob 23 is arranged outside the housing 1. A Mark 24 on the adjusting button 23 serves as an optical display an adjustment dimension, characterized by one on the External wall of the housing 1 attached scale 26.

An einem zweiten Ende der nach unten gerichteten Koppel 14 ist ein Saugerträger 27 angelenkt. Der Saugerträger 27 trägt an seinem der Koppel 14 abgewandten Ende eine rohrförmige Traverse 28, auf der mindestens ein Hubsauger 29 angeordnet ist. Der Saugerträger 27 weist drei voneinander beabstandete, drehbar gelagerte Führungsrollen 31,32,33 auf, die zur Erzielung einer Vertikalbewegung mit einer gehäusefesten senkrecht angeordneten Führungsschiene 34 in Wirkkontakt stehen. Hierbei sind die Rollen 31,32 auf einer gedachten Vertikalen angeordnet. Die dritte Rolle 33 ist seitlich der gedachten Vertikalen angeordnet, so daß die Rollen 31,32,33 die Eckpunkte eines gedachten Dreiecks bilden.At a second end of the downward coupling 14 is a suction cup 27 articulated. The suction cup 27 carries a tubular one at its end facing away from the coupling 14 Traverse 28, on which at least one lifting vacuum 29 is arranged is. The suction cup 27 has three spaced apart rotatably mounted guide rollers 31,32,33, which for Achieving a vertical movement with a housing-fixed vertically arranged guide rail 34 in operative contact stand. Here, the rollers 31, 32 are imaginary Arranged vertically. The third roller 33 is on the side imaginary verticals arranged so that the rollers 31,32,33 form the corner points of an imaginary triangle.

Der Bolzen 13 der Gelenkverbindung der Koppeln 12,14,16 liegt in einer "übergabeposition" auf einer gemeinsamen gedachten Geraden, die gleichzeitig die Mittellinie der Achse 21 ist. Die "übergabeposition" definiert die Stellung des Hubsaugers 29 zu mindestens einem in gleicher Höhe über dem Bogenstapel 3 angeordneten Schleppsauger 36, an den ein vom Bogenstapel 3 mittels des Hubsaugers 29 angehobener Bogen zum Weitertransport an die Bogenverarbeitungsmaschine übergeben wird.The bolt 13 of the articulation of the couplers 12, 14, 16 is located in a "transfer position" on a common imaginary Straight line, which is also the center line of axis 21. The "transfer position" defines the position of the Lifting vacuum 29 to at least one at the same height above the Sheet stack 3 arranged drag vacuum 36, to which one of the Sheet stack 3 by means of the lifting suction 29 raised sheet for Pass on to the sheet processing machine becomes.

Eine "Ansaugposition" definiert die Stellung des Hubsaugers 29, die dieser bei der Übernahme eines Bogens vom Bogenstapel 3 einnimmt. Hierbei befindet sich der Hubsauger 29 in einem Abstand a (a = ca. 0-15mm) von der Oberfläche des Bogenstapels 3. Ein Hub s des Hubsaugers 29 von der "Ansaugposition" in die "übergabeposition" beträgt s = ca. 13 bis 28mm, je nach eingestelltem Abstand a. An "intake position" defines the position of the Hubsaugers 29 which this when taking over a sheet from Sheet stack 3 takes. Here is the Vacuum cleaner 29 at a distance a (a = approx. 0-15mm) from the Surface of the sheet stack 3. One stroke s of the suction cup 29 from the "suction position" to the "transfer position" is s = approx. 13 to 28mm, depending on the set distance a.

Eine durch die Kontur der Steuerscheibe 4 zyklisch angeregte Schwenkbewegung des Rollenhebels 9 erfolgt um die Achse 11. über die Koppeln 12,16 wird die Gelenkverbindung (Bolzen 13) auf eine Kurvenbahn K gezwungen. Die Kurvenbahn K hat ihren Anfangspunkt auf der gedachten Mittellinie 35 (entspricht der "übergabeposition") und verläuft in einem Radius r1 (r1 = Länge der Koppel 16) um den gemeinsamen Anlenkpunkt 20 von Koppel 16 und Stellhebel 18. Die Lage dieses Anlenkpunktes 20 ist mittels des Stellknopfes 23 durch Verschwenken des Stellhebels 18 einstellbar. Hierbei erfolgt eine Verstellung durch Verschwenken des Anlenkpunktes 20 in einem Radius r2 (r2 = r1 = Länge des Hebelarms 18) um die gedachte Mittellinie 35. Bei dieser Verstellung wird jeweils eine neue Kurvenbahn K eingestellt, die jeweils denselben Anfangspunkt (entspricht "Übergabeposition") aufweist.A pivoting movement of the roller lever 9, which is cyclically excited by the contour of the control disc 4, takes place about the axis 11. The cam track K has its starting point on the imaginary center line 35 (corresponds to the "transfer position") and runs in a radius r 1 (r 1 = length of the coupling 16) around the common articulation point 20 of the coupling 16 and adjusting lever 18. The position of this articulation point 20 is adjustable by means of the adjusting knob 23 by pivoting the adjusting lever 18. Here, an adjustment is made by pivoting the articulation point 20 in a radius r 2 (r 2 = r 1 = length of the lever arm 18) about the imaginary center line 35. With this adjustment, a new cam track K is set in each case, each of which has the same starting point (corresponds to " Transfer position ").

Durch die verschiedenen einstellbaren Abstände der Kurvenbahnen K,Kn zum Hubsauger 29 ist der Hub s und darausfolgend der Abstand a stufenlos einstellbar.The stroke s and, consequently, the distance a can be infinitely adjusted by means of the different adjustable distances of the cam tracks K, K n to the suction cup 29.

Bei einem zweiten Ausführungsbeispiel ist statt der Koppel 16 eine Führungsrolle 37 vorgesehen. Diese sitzt drehbar auf dem Bolzen 13 und steht in Führkontakt mit einer schwenkbar gelagerten Führungsschiene 38. Der Schwenkpunkt der Führungsschiene 38 liegt auf oder in unmittelbarer Nähe der Mittellinie 35, so daß die Führungsrolle 37 in der "übergabeposition" auf der Mittellinie 35 liegt. Die Führungsschiene 38 kann je nach gewünschter Hubcharakteristik einen geraden oder gekrümmten Verlauf aufweisen. In a second exemplary embodiment, instead of the coupling 16 a guide roller 37 is provided. This sits rotatably on the Bolt 13 and is in guide contact with a pivotable mounted guide rail 38. The pivot point of the Guide rail 38 lies on or in the immediate vicinity of the Center line 35 so that the guide roller 37 in the "Transfer position" is on the center line 35. The Guide rail 38 can, depending on the desired stroke characteristics have a straight or curved course.
