Description

Die Erfindung betrifft ein Perforiergerät mit einer beweglichen Einrichtung, an der eine Halterung für ein Perforiermittel angebracht werden kann, sowie ein verfahren sur Justierung eines lerforiergerätes gemäß dem Oberbegriff des Anspruchs 11.The invention relates to a Perforiergerät with a movable device to which a Holder for a perforating can be attached, and a method sur adjustment of a lerforiergerätes according to the preamble of claim 11th

Ein derartiges Perforiergerät bzw. Verfahren ist beispielsweise aus der DE 34 39 199 C1 bekannt. Beim Einsatz eines Perforiergerätes der genannten Art wird ein Bogen unter dem Perforiergerät vorbeigeführt. Mit Hilfe einer Perforierscheibe, die an einer Halterung drehbar gelagert ist, wird dann in den darunter bewegten Papierbogen eine Perforierung eingebracht oder der Bogen geschnitten. Dabei wird ein Kolben mit Druckluft beaufschlagt und dadurch nach oben oder unten bewegt. Die Elemente des Perforiergerätes sind in einem sogenannten Perforierkopf vereinigt, der üblicherweise an einer Traverse in einer Falzmaschine befestigt ist, um das Perforieren in der Falzmaschine geförderten Blattgutes zu ermöglichen.Such a Perforiergerät or method is known for example from DE 34 39 199 C1. At the Use of a Perforiergerätes of the type mentioned is an arc under the perforator past. With the aid of a perforating disc, which is rotatably mounted on a holder, Then a perforation is placed in the moving paper sheet or the Bow cut. In this case, a piston is pressurized with compressed air and thereby moved up or down. The elements of the Perforiergerätes are in a so-called Perforating combined, usually attached to a crossbar in a folding machine is to allow the perforation promoted in the folding machine sheet material.

Bislang ist die Justage des Perforierkopfes nur eingeschränkt möglich, da eine Höheneinstellung nur durch Änderung der Höhenposition des Perforierkopfes an der Traverse möglich ist.So far, the adjustment of the perforating head is limited possible, as a Height adjustment only by changing the height position of the perforating head on the Traverse is possible.

Bei der Perforierung von Blattgut ist es jedoch besonders wichtig, die Eindringtiefe des Schneide- oder Perforiermessers exakt zu justieren, so dass es in jedem Fall möglich ist, die gewünschte Perforierung oder den gewünschten Schnitt anzubringen. Insbesondere bei der Durchführung von Perforierarten, bei denen das Perforiermesser lediglich zum Teil, etwa zur Hälfte in das darunter vorbeilaufende Blattgut eindringen soll, ist es besonders wichtig, die Eindringtiefe des Perforiermessers in das Blattgut exakt zu justieren. Dies wird besonders deutlich, wenn man berücksichtigt, dass die Dicke des Blattes typischerweise im Bereich von 0,1 mm liegt. Da die Weglänge beim Heben und Senken des Perforierkopfes exakt gesteuert werden kann, muß entsprechend die Nullpunkt Einstellung, d. h. also die Einstellung der Ausgangsposition des Perforiermessers vor dem Senken in das zu perforierende Blattgut exakt eingestellt werden.In the perforation of sheet material, however, it is particularly important to the penetration depth of Cutting or Perforiermessers adjust exactly so that it is possible in any case, the desired perforation or the desired cut to install. Especially at the Execution of Perforierarten, in which the perforator only partially, for example Half of it is to penetrate into the sheet material passing underneath, it is particularly important to precisely adjust the penetration depth of the perforating blade into the sheet material. this will especially clear, considering that the thickness of the sheet is typically in the Range of 0.1 mm. Because the path length when lifting and lowering the perforating head must be accurately controlled, the zero point adjustment must be accordingly, d. H. so the Adjusting the starting position of the perforator before lowering into the perforating sheets are set exactly.

Aufgabe der vorliegenden Erfindung ist es daher, ein Perforiergerät bzw. Perforierverfahren vorzuschlagen, mit dem eine genaue Positionierung der Ausgangslage des Schneide- oder Perforiermessers möglich ist.Object of the present invention is therefore to propose a Perforiergerät or perforation, with the precise positioning of the initial position of the cutting or Perforiermessers possible is.

Diese Aufgabe wird erfindungsgemäß durch ein Perforiergerät mit den Merkmalen gemäß Anspruch 1 sowie durch ein Verfahren mit den Merkmalen gemäß Anspruch 11 gelöst.This object is achieved according to a Perforiergerät with the features Claim 1 and by a method having the features of claim 11 solved.

Das Vorsehen einer Positioniereinrichtung, die direkt auf einen Zylinder des Perforiergeräts wirkt, um diesen in seiner Grundposition einzustellen, hat eine Vielzahl von Vorteilen. So ist es damit möglich, die Ausgangsposition des Zylinders und in dessen Folge die Ausgangsposition des Bearbeitungsmittels also insbesondere des Schneide- oder Perforiermessers vor dem Absenken in das zu perforierende Blattgut, exakt festzulegen.The provision of a positioning device directly on a cylinder of the perforator working to set this in its basic position has a host of benefits. So is It makes it possible, the starting position of the cylinder and in consequence the Starting position of the processing means so in particular the cutting or Perforating before lowering into the sheet material to be perforated, set exactly.

In einer besonders bevorzugten Ausführungsform, bei der eine Differenzialschraube verwendet wird, besteht darüber hinaus der Vorteil, dass damit eine exakte Positionierung stufenlos und sehr feinfühlig möglich ist. Die Differenzialschraube besitzt zwei Gewinde unterschiedlicher Steigung. Die Differenz der Steigungen, die erheblich kleiner gehalten werden kann als die Steigung eines einzelnen Gewindes, legt den Einstellweg pro Umdrehung der Differenzialschraube fest. Die Differenzialschraube kann in einer speziellen Ausführungsform über ein Innengewinde in direktem Kontakt zu dem Zylinder des Perforiergerätes stehen und weiterhin ein Außengewinde aufweisen.In a particularly preferred embodiment, in which a differential screw In addition, there is the advantage that with it an exact positioning stepless and very sensitive is possible. The differential screw has two threads different slope. The difference of the slopes, which kept considerably smaller can be considered the pitch of a single thread, sets the adjustment path per Turn the differential screw firmly. The differential screw can be in a special Embodiment via an internal thread in direct contact with the cylinder of the Perforating stand and continue to have an external thread.

Das in Figur 1 gezeigte erfindungsgemäße Perforiergerät weist eine Halterung 10 auf, an der ein Perforiermittel 12 an einer Achse 14 drehbar befestigt werden kann. Die Halterung 10 ist an einer beweglichen Einrichtung 16 - hier in Form einer Kolbenstange - befestigt, so dass sie bei einer Bewegung der Kolbenstange bewegt wird. Zur geradlinigen Führung sind beidseitig Führungsbuchsen 18 und 20 vorgesehen, die ein Verdrehen der Halterung 10 um die Längsachse der Kolbenstange verhindern.The perforating device according to the invention shown in FIG. 1 has a holder 10 on which a perforating means 12 can be rotatably mounted on an axle 14. The Holder 10 is on a movable device 16 - here in the form of a piston rod - attached so that it is moved during a movement of the piston rod. To the straightforward Guide are provided on both sides guide bushings 18 and 20, which is a twisting of the Prevent holder 10 around the longitudinal axis of the piston rod.

Die Bewegung der Kolbenstange und in deren Folge die Bewegung des Perforiermittels 12 nach unten erfolgt dadurch, dass ein Luftraum 22 in einem Zylinder 24 mit Druck, insbesondere Luftdruck beaufschlagt wird, während der Zylinder 24 fixiert ist. Der Druck bewegt einen, in dem Zylinder 24 geführten, die Kolbenstange tragenden, Perforierkolben 26 nach unten.The movement of the piston rod and as a result the movement of the perforating 12th downwards takes place in that an air space 22 in a cylinder 24 with pressure, In particular, air pressure is applied while the cylinder 24 is fixed. The pressure moves a, in the cylinder 24 guided, the piston rod bearing, perforating 26 down.

Zur Einstellung einer exakten Ausgangsposition des Perforiermittels 12 oder eines Schneidrades wird eine so genannte Nullposition des Zylinders 24 relativ zu einer Gehäusekante 28 eines Gehäuses 33 eingestellt. Zur Einstellung der Nullposition des Zylinders 24 ist eine Positioniereinrichtung 30 vorgesehen. Mittels dieser ist die Ausgangslage der Kolbenstange 24 einstellbar. Vorteilhafterweise weist die Positioniereinrichtung 30 ein Außengewinde 31 sowie ein Innengewinde 29 auf, deren Steigerungen unterschiedlich sind. Sie kann insbesondere als Differenzialschraube ausgeführt sein. In der beschriebenen Ausführungsform weist die Differenzialschraube ein Außengewinde 31, sowie ein Innengewinde 29 auf. Das Außengewinde 31 greift in eine am Gehäuse 33 fixierte Mutter 32 ein, während das Innengewinde 29 unmittelbar in Verbindung mit einem entsprechenden Gewinde des Zylinders 24 steht. Das Außengewinde 31 der Differenzialschraube hat eine andere, z. B. größere Ganghöhe als ihr Innengewinde 29. Beispielsweise kann für das Außengewinde 31 ein Gewinde von 1,25 mm Ganghöhe vorgesehen werden, während das Innengewinde 29 eine Ganghöhe von 1 mm aufweist. For setting an exact starting position of the perforating 12 or a Cutting wheel is a so-called zero position of the cylinder 24 relative to a Housing edge 28 of a housing 33 is set. For setting the zero position of the Cylinder 24 is a positioning device 30 is provided. By means of this is the Initial position of the piston rod 24 adjustable. Advantageously, the Positioning device 30, an external thread 31 and an internal thread 29, whose Increases are different. In particular, it can be used as a differential screw be executed. In the described embodiment, the differential screw has a External thread 31, and an internal thread 29 on. The external thread 31 engages in an am Housing 33 fixed nut 32, while the internal thread 29 directly in Connection with a corresponding thread of the cylinder 24 is. The external thread 31 of the differential screw has another, z. B. greater pitch than its internal thread 29. For example, for the external thread 31, a thread of 1.25 mm pitch be provided while the internal thread 29 has a pitch of 1 mm.

Beim Herausdrehen der Differenzialschraube aus der Mutter 32 dreht sich erstere entsprechend der Ganghöhe des Außengewindes 31 relativ zur Mutter 32, also beispielsweise um 1,25 mm je Umdrehung nach oben. Gleichzeitig wird durch die Drehung der Differenzialschraube der Zylinder 24 entsprechend dem Innengewinde 29 der Differenzialschraube, also beispielsweise um 1 mm je Umdrehung nach unten bewegt. Da die Mutter 32 über eine Madenschraube 34 mit dem Gehäuse 33 drehsicher verbunden ist, ergibt sich aus der Drehung der Differenzialschraube nach oben eine kombinierte Bewegung der Differenzialschraube nach oben sowie des Zylinders 24 nach unten. Der relative Weg, den der Zylinder 24 gegenüber der Gehäusekante 28 zurücklegt, entspricht pro Umdrehung der Differenz zwischen den Ganghöhen des Außengewindes 31 und des Innengewindes 29. Bei einem Außengewinde von 1,25 mm und Innengewinde von 1 mm ergibt sich entsprechend ein relativer Weg von 0,25 mm bei einer vollen Umdrehung der Differenzialschraube 30, so dass eine Feinpositionierung des Zylinders 24 mit einer Genauigkeit von 0,25 mm pro Umdrehung gewährleistet werden kann.When unscrewing the differential screw from the nut 32, the former rotates according to the pitch of the external thread 31 relative to the nut 32, ie for example, by 1.25 mm per revolution upwards. At the same time, by the rotation the differential screw of the cylinder 24 corresponding to the internal thread 29 of the Differential screw, so for example by 1 mm per revolution moves down. There the nut 32 is rotatably connected via a grub screw 34 with the housing 33, The result of the rotation of the differential screw upwards is a combined movement the differential screw up and the cylinder 24 down. The relative path the cylinder 24 travels with respect to the housing edge 28, corresponds per revolution the difference between the pitches of the external thread 31 and the internal thread 29th With an external thread of 1.25 mm and internal thread of 1 mm results Accordingly, a relative distance of 0.25 mm for a full turn of Differential screw 30, so that a fine positioning of the cylinder 24 with a Accuracy of 0.25 mm per revolution can be guaranteed.

In einer besonders bevorzugten Ausführungsform sind in der Differenzialschraube wie auch im Zylinder 24 fluchtende Bohrungen vorgesehen, in welche eine Schraube 36 eingedreht werden kann. Die Schraube 36 wird nach dem Eindrehen mit einem Stift 38 gegen Verdrehen bezüglich der Differenzialschraube gesichert. Weiterhin ist zwischen dem Kopf der Schraube 36 und einer an der Differenzialschraube ausgebildeten Schulter 42 ein Tellerfederpaket 40 vorgesehen. Die Schraube 36 und das Tellerfederpaket 40 eliminieren ein eventuell vorhandenes Gewindespiel zwischen der Differenzialschraube und dem Zylinder 24.In a particularly preferred embodiment are in the differential screw as well provided in the cylinder 24 aligned bores into which a screw 36 is screwed can be. The screw 36 is after screwing with a pin 38 against Twist with respect to the differential screw secured. Furthermore, between the head the screw 36 and a formed on the differential screw shoulder 42 a Cup spring package 40 is provided. The screw 36 and the plate spring package 40 eliminate a possibly existing thread clearance between the differential screw and the Cylinder 24.

Beim Drehen der Differenzialschraube wird auch die Schraube 36 mitgedreht, da diese mit Hilfe des Stiftes 38 an der Differenzialschraube gesichert ist. Durch das zusätzliche Vorsehen des Tellerfederpakets 40 wird ein Selbstsicherungseffekt erzielt, der die Differenzialschraube 30 in der jeweils gewünschten Position sichert. When turning the differential screw and the screw 36 is rotated, since this with Help the pin 38 is secured to the differential screw. By the additional Providing the plate spring package 40, a self-locking effect is achieved, which is the Differential screw 30 secures in the respectively desired position.

Besonders vorteilhaft an dieser Ausführungsform ist, dass die Nullpunktseinstellung des Zylinders 24 auch bei laufenden Maschinen vorgenommen und eventuell erforderliche Korrekturen noch im Lauf der Maschine durchgeführt werden können.Particularly advantageous in this embodiment is that the zero point adjustment of the Cylinder 24 also made with running machines and possibly required Corrections can still be made in the course of the machine.

Das Eliminieren des Gewindespieles sowie die Selbstsicherung der Differenzialschraube durch eine Kombination aus der Schraube 36 und eines Federmechanismus, wie beispielsweise des Tellerfederpakets 40 erhöht die Lebensdauer der Feineinstellung erheblich. Neben der Eliminierung des Gewindespieles zwischen der Differenzialschraube und dem Zylinder 24 ist es auch vorteilhaft, das Gewindespiel zwischen der Differenzialschraube und der Mutter 32 zu eliminieren. Zu diesem Zweck wird in vorteilhafter Weise eine Einstellmutter 44 vorgesehen, die in das Außengewinde 31 eingreift und einen Federmechanismus, insbesondere ein Wellenfederpaket 46 gegen die Mutter 32 drückt und damit das Entstehen eines Gewindespieles zwischen dem Außengewinde 31 der Differenzialschraube und der Mutter 32 im Wesentlichen verhindert.The elimination of the thread play as well as the self-assurance of the differential screw by a combination of the screw 36 and a spring mechanism, such as For example, the plate spring package 40 increases the life of the fine adjustment considerably. In addition to the elimination of the thread clearance between the differential screw and the cylinder 24, it is also advantageous to play the thread between the To eliminate differential bolt and nut 32. For this purpose, in Advantageously, an adjusting nut 44 is provided, which engages in the external thread 31 and a spring mechanism, in particular a wave spring package 46 against the nut 32nd presses and thus the emergence of a thread clearance between the external thread 31 of Differential screw and the nut 32 substantially prevented.

In den Figuren 2a und 2b sind zwei unterschiedliche Positionierungen des Zylinders gezeigt, die mit Hilfe der erfindungsgemäßen Positioniereinrichtung vorgenommen werden können. In Figur 2a ist die Differenzialschraube zusammen mit der Schraube 36, die durch den Stift 38 drehgesichert ist, und dem Tellerfederpaket 40 in den Zylinder 24 eingedreht. Der Zylinder 24 ist durch zwei Stifte 48 gegen Verdrehen gegenüber dem Gehäuse 33 gesichert. Das untere Ende des Zylinders 24 ist durch das Eindrehen der Differenzialschraube in die Position A gebracht. Beim Herausdrehen der Differenzialschraube bewegt sich diese gegenüber der Mutter 32 entsprechend der Steigung des Außengewindes 31 der Differenzialschraube nach oben. Gleichzeitig bewegt sich der Zylinder 24 gegenüber der Differenzialschraube entsprechend dem Innengewinde 29 der Differenzialschraube nach unten, so dass sich die resultierende Gesamtbewegung aus der Differenz der Steigungen zwischen dem Außen- und dem Innengewinde ergibt. Nach dem Herausdrehen der Differenzialschraube in die in Figur 2b gezeigte Position ergibt sich aufgrund der beiden gegenläufigen Bewegungen eine resultierende Position B des der Halterung 10 (nicht gezeigt) zugewandten Endes des Zylinders 24. Auf diese Weise lässt sich eine exakte Einstellung der Ausgangsposition des Zylinders 24 in einem Bereich d einstellen, so dass die Perforiereinrichtung bequem auch während des Betriebes auf die jeweils erforderliche Perforiertiefe eingestellt werden kann. FIGS. 2a and 2b show two different positions of the cylinder, which can be made with the help of the positioning device according to the invention. In Figure 2a, the differential screw is together with the screw 36 passing through the pin 38 is secured against rotation, and the disc spring assembly 40 is screwed into the cylinder 24. Of the Cylinder 24 is secured by two pins 48 against rotation relative to the housing 33. The lower end of the cylinder 24 is by screwing the differential screw in the Position A brought. When unscrewing the differential screw moves this relative to the nut 32 corresponding to the pitch of the external thread 31 of the Differential screw upwards. At the same time, the cylinder 24 moves relative to the Differential screw according to the internal thread 29 of the differential screw to below, so that the resulting total movement from the difference of the slopes between the outer and the inner thread results. After unscrewing the Differential screw in the position shown in Figure 2b results from the two opposite movements a resulting position B of the holder 10 (not shown) facing the end of the cylinder 24. In this way, can be an exact Adjust setting of the initial position of the cylinder 24 in a range d, so that the Perforiereinrichtung comfortable even during operation on each required perforation depth can be adjusted.
