Abstract

A device for positive alignment and tensioning of a printing plate on a printing machine with a cylindrical platen. The platen cylinder has a recessed channel containing a plate tensioning arrangement comprising a forward clamp unit and a rear clamping and tension unit. The forward clamp has locating guide elements (541a,b) which correspond with locating holes (12a,b) in the plate to assure correct lateral and peripheral registering on the platen. The locating elements are electrically insulated from the printing plate, and have electrode inserts (542a,b) connected to the press control unit. The electrodes are provided with contact heads (543a,b) arranged so as to only contact the base of the generally U-shaped locating cut-outs in the printing plates.

Description

Die Erfindung betrifft eine Vorrichtung zum registergerechten Aufspannen einer Druckplatte, wobei die Druckplatte auf einem Plattenzylinder einer Bogendruckmaschine gespannt wird, der Plattenzylinder eine in einem Plattenzylinder-Kanal angeordnete, aus einer vorderen Klemmeinrichtung und einer hinteren Klemm- und Spanneinrichtung bestehende Plattenspanneinrichtung aufweist und in der vorderen Klemmeinrichtung die registergerechte Lage in Seiten- und Umfangsrichtung sichernde und erfassende Pass-Elemente angeordnet sind, die mit in die Druckplatte eingebrachten Passlöchern korrespondieren und mit einer Steuereinheit verbunden sind.The invention relates to a device for register-correct clamping of a printing plate, the printing plate being clamped on a plate cylinder of a sheet-fed printing machine, the plate cylinder is arranged in a plate cylinder channel, from a front Clamping device and a rear clamping and tensioning device existing plate tensioning device has and in the front clamping device the correct position Passive elements securing and capturing in the lateral and circumferential direction are arranged, which correspond with the pass holes made in the pressure plate and with a control unit are connected.

Aus dem DE-GM 77 28 905 ist eine derartige Vorrichtung bekannt, bei der Pass-Stifte in der vorderen Klemmeinrichtung und gegenüber dieser isoliert angeordnet sind. Die Pass-Stifte sind mit einer Spannungsquelle und einem Signalgeber verbunden, so dass bei Kontaktnahme der Pass-Stifte mit den in den Druckplatten vorgesehenen Passlöchern ein Stromkreis geschlossen und damit der Signalgeber aktiviert wird.From DE-GM 77 28 905 such a device is known in the dowel pins in the front clamping device and are arranged isolated from this. The passport pens are connected to a voltage source and a signal generator, so that when contact is made of the dowel pins with the dowel holes provided in the pressure plates closed and the signal transmitter is activated.

Nachteilig ist, dass der Signalgeber auch dann anspricht, wenn die Druckplatte nicht exakt registergerecht ausgerichtet ist. Das ist z.B. der Fall, wenn im Bereich der Passlöcher Verformungen oder zu große Toleranzen auftreten und ein Schrägstellen der Druckplatte erfolgt. Der Signalgeber wird auch dann aktiviert, wenn z.B. der seitliche Versatz der Druckplatte so groß ist, dass die Vorderkante der Druckplatte an den Pass-Stiften anliegt oder bei der Verwendung von U-förmigen, zur Druckplattenvorderkante hin geöffneten Passlöchern, wenn die Pass-Stifte bereits an einem Schenkel der Passlöcher anliegen, also ohne den eine registergerechte Lage sichernden Bodenbereich der Passlöcher zu erreichen.It is disadvantageous that the signal transmitter responds even if the pressure plate is not exact is aligned in accordance with the register. This is e.g. the case when deformations in the area of the pass holes or too large tolerances occur and the printing plate is tilted. The signal generator is also activated if e.g. the lateral offset of the pressure plate like this It is great that the front edge of the pressure plate lies against the dowel pins or during use of U-shaped fitting holes open towards the front of the printing plate, if the dowel pins are already on one leg of the dowel holes, i.e. without the one in register To reach the position securing bottom area of the pass holes.

Diese Nachteile sollen durch eine Vorrichtung der EP 581 212 B1 beseitigt werden. Die Pass-Stifte dieser Vorrichtung sind ebenfalls gegenüber der Klemmeinrichtung isoliert angeordnet sowie mit einer Spannungsquelle und einem Signalgeber verbunden. Darüber hinaus weist die Mantelfläche der Pass-Stifte eine Isolierung auf, die partiell mit einem leitfähigen Abschnitt versehen ist, der so angeordnet ist, dass nur der Bodenbereich eines Passlochs detektiert wird.These disadvantages are to be eliminated by a device of EP 581 212 B1. The Dowel pins of this device are also isolated from the clamping device as well as connected to a voltage source and a signal generator. Furthermore the outer surface of the dowel pins has insulation that is partially conductive Section is provided, which is arranged so that only the bottom portion of a fitting hole is detected.

Diese Vorrichtung hat den Nachteil, dass die Fertigung der Pass-Stifte aufwendig ist. Da die isolierende Mantelfläche starken Belastungen ausgesetzt ist, wird entweder diese Mantelfläche oder der gesamte Stift aus keramischen Material gefertigt. Dieses wiederum ist den auf tretenden schlagartigen Belastungen nicht gewachsen, so dass eine eminente Bruchgefahr besteht.This device has the disadvantage that the production of the dowel pins is complex. Since the insulating jacket surface is exposed to heavy loads, either this jacket surface or the entire pen is made of ceramic material. This in turn is on occurring sudden loads can not cope with, so an eminent risk of breakage consists.

Aufgabe der Erfindung ist es, eine Vorrichtung zur Kontrolle der registergerechten Lage einer Druckplatte zu schaffen, die mit einfachen Mitteln zu realisieren und die den schlagartig auftretenden Belastungen durch die Druckplatte gewachsen ist.The object of the invention is to provide a device for checking the correct position of a To create a printing plate that can be realized with simple means and that that occurs suddenly Loads have grown due to the pressure plate.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruchs 1 gelöst.According to the invention the object is achieved by the features of claim 1.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass nunmehr ein verschleiß- und bruchsicheres Passelement verfügbar ist, das kostengünstig herstellbar ist und eine sichere Funktion garantiert.The advantages achieved by the invention consist in particular in that now a wear-resistant and shatterproof fitting element is available, which is inexpensive to manufacture and guaranteed safe functioning.

Wie aus der Figur 1 ersichtlich, ist in einem Druckplatten-Magazin 2 eine Druckplatte 1 zwischengelagert. Diese ruht dort auf zwei in einem Abstand zueinander angeordneten Vorpass-Stiften 21a; 21b, die mit Passlöchern in Form von Ausstanzungen 12a, 12b (siehe hierzu die Figur 2) der Druckplatte 1 korrespondieren.As can be seen from FIG. 1, a printing plate 1 is temporarily stored in a printing plate magazine 2. There it rests on two pre-fit pins arranged at a distance from one another 21a; 21b, which have pass holes in the form of punched-out portions 12a, 12b (see in this regard the figure 2) of the pressure plate 1 correspond.

Die Ausstanzungen 12a, 12b unterscheiden sich hinsichtlich ihrer Form voneinander. Die Ausstanzung 12a weist einen flachen Bodenbereich auf, während die Ausstanzung 12b einen Radius im Bodenbereich aufweist (siehe hierzu Fig. 2). Beiden gemeinsam ist ein beidseitige Einführ-Schräge 121 a, 121b. Die mit den Vorpass-Stiften korrespondierenden Ausstanzungen 12a, 12b sind aneinander hinsichtlich ihrer Form angepasst. Das bedeutet konkret, dass in die Ausstanzung 12b ein runder Vorpass-Stift 21b (nicht dargestellt) eingreift, wobei dessen Radius dem Radius der Ausstanzung 12b angepasst ist. Die Ausstanzung 12a nimmt einen Vorpass-Stift 21 a auf, dessen Kontaktzone mit der Druckplatte 1, das heißt mit dem Bodenbereich der Ausstanzung 12a, eben ausgeführt ist. Die Seitenflächen der Ausstanzung 12a haben keinen Kontakt mit dem Vorpass-Stift 21a.The cutouts 12a, 12b differ from one another in terms of their shape. The Punch 12a has a flat bottom area, while punch 12b has one Radius in the bottom area (see Fig. 2). Common to both is a bilateral Insertion bevel 121a, 121b. The cut-outs corresponding to the pre-pass pens 12a, 12b are adapted to one another in terms of their shape. That means specifically that a round pre-fitting pin 21b (not shown) engages in the cutout 12b, the radius of which is adapted to the radius of the punched-out portion 12b. The die cut 12a takes a Vorpass pin 21 a, the contact zone with the pressure plate 1, that is the bottom area of the cutout 12a is flat. The side surfaces of the cut-out 12a have no contact with the prefitting pin 21a.

Das Druckplatten-Magazin 2 ist in seiner Ruhestellung fest an dem nicht dargestellten Gestell der Druckmaschine angebracht.The printing plate magazine 2 is fixed in its rest position on the frame, not shown attached to the press.

Ebenfalls im Gestell gelagert ist ein Plattenzylinder 4. Dieser ist dazu bestimmt, auf seiner Oberfläche die aus dem Druckplatten-Magazin 2 zugeführten Druckplatten 1 aufzunehmen. Zu diesem Zwecke ist an seinem Umfang in achsparalleler Richtung ein Plattenzylinder-Kanal 41 angeordnet. Im Plattenzylinder-Kanal 41 befindet sich eine Plattenspanneinrichtung 7. Diese besteht aus einer vorderen Klemmeinrichtung 5 und einer hinteren Klemm- und Spanneinrichtung 6 zur Aufnahme des Druckplatten-Endes, wobei die vordere Klemmeinrichtung eine obere Klemmschiene 52 und eine untere Klemmschiene 51 umfasst. Die obere Klemmschiene 52 ist fest am Plattenzylinder-Kanal 41 angeordnet. Die untere Klemmschiene 51 ist gegen die obere Klemmschiene 52 zum Klemmen der Druckplatte 1 verschiebbar.A plate cylinder 4 is also mounted in the frame Surface to receive the printing plates 1 fed from the printing plate magazine 2. For this purpose, there is a plate cylinder channel on its circumference in the axis-parallel direction 41 arranged. A plate clamping device is located in the plate cylinder channel 41 7. This consists of a front clamping device 5 and a rear clamping and Clamping device 6 for receiving the pressure plate end, the front clamping device includes an upper clamp rail 52 and a lower clamp rail 51. The upper Clamping rail 52 is fixed to the plate cylinder channel 41. The lower clamp rail 51 is displaceable against the upper clamping rail 52 for clamping the pressure plate 1.

Der vorderen Klemmeinrichtung 5 sind im Bereich der Klemmschienen 51, 52 als Pass-Stifte 54a, 54b ausgeführte Pass-Elemente zugeordnet. Aus der Figur 2 ist ersichtlich, dass die Pass-Stifte 54a, 54b in einem endlichen, dem Abstand zwischen den Vorpass-Stiften 21a; 21b entsprechenden Abstand zueinander angeordnet sind. Dabei hat der Pass-Stift 54a analog zum Vorpass-Stift 21a eine flache Kontaktfläche zum Bodenbereich der Ausstanzung 12a, während der Pass-Stift 54b eine dem Radius der Ausstanzung 12b angepasste Form im Bereich der Kontaktzone aufweist.The front clamping device 5 are in the area of the clamping rails 51, 52 as dowel pins 54a, 54b assigned pass elements. It can be seen from FIG. 2 that the dowel pins 54a, 54b in a finite, the distance between the pre-pass pins 21a; 21b corresponding distance to each other are arranged. The passport pen 54a analogous to the pre-fitting pin 21a, a flat contact surface to the bottom area of the Die cut 12a, while the dowel pin 54b is adapted to the radius of the die cut 12b Has shape in the area of the contact zone.

Der Aufbau der Pass-Stifte 54a, 54b ist aus den Figuren 3 und 4 ersichtlich. Beide Pass-Stifte bestehen im Wesentlichen aus einem Fuß 547a, 547b, auf dem ein Führungskörper 541a, 541b aufgesetzt und mit diesem fest verbunden ist. In den Figuren 3 und 4 ist eine Draufsicht in Richtung der Achse der Pass-Stifte 54a, 54b dargestellt, wobei die Zeichnung als ein Schnitt durch den Führungskörper 541 a, 541b ausgeführt ist. The structure of the dowel pins 54a, 54b can be seen from FIGS. 3 and 4. Both pass pins consist essentially of a foot 547a, 547b on which a guide body 541a, 541b placed and firmly connected to this. In Figures 3 and 4 is one Top view in the direction of the axis of the dowel pins 54a, 54b shown, the drawing is executed as a section through the guide body 541 a, 541b.

Rechtwinklig zur Achse der Pass-Stifte 54a, 54b - in Förderrichtung der Druckplatte 1 - ist eine Bohrung in den Führungskörper 541 a, 541b eingebracht, die einen Einsatz 542a, 542b aufnimmt. Dieser ist gegenüber dem Führungskörper 541a, 541b über eine Isolierbuchse 544a, 544b elektrisch isoliert und mit einem elektrischen Abgriff 548a, 548b versehen. Die elektrischen Abgriffe 548a, 548b sind mit einer hier nicht dargestellten Steuereinheit verbunden. Die Befestigung des Einsatzes 542a, 542b im Führungskörper 541a, 541b erfolgt im Ausführungsbeispiel durch eine Sechskantmutter, die den Einsatz 542a, 542b über eine zwischengelegte Isolierscheibe 545a, 545b gegenüber dem Führungskörper 541 a, 541b verspannt.At right angles to the axis of the dowel pins 54a, 54b - in the conveying direction of the pressure plate 1 - introduced a hole in the guide body 541 a, 541b, which an insert 542a, 542b records. This is opposite the guide body 541a, 541b via an insulating bush 544a, 544b electrically insulated and provided with an electrical tap 548a, 548b. The electrical taps 548a, 548b are connected to a control unit, not shown here. The insert 542a, 542b is fastened in the guide body 541a, 541b in the Embodiment by a hexagon nut, the insert 542a, 542b interposed Insulating washer 545a, 545b braced against the guide body 541 a, 541b.

Beide Einsätze 542a,542b besitzen einen Tastkopf 543a, 543b. Die Tastköpfe 543a, 543b unterscheiden sich hinsichtlich ihrer Form. Der Tastkopf 543a ist in seinem Kontaktbereich mit der Ausstanzung 12a deren flachen Bodenbereich angepasst und ebenfalls als ebene Fläche ausgeführt . Der Tastkopf 543b hingegen weist eine Kontaktfläche auf, die dem Radius der Aussparung 12b angepasst ist.Both inserts 542a, 542b have a probe 543a, 543b. The probes 543a, 543b differ in their shape. The probe 543a is in its contact area with the punched-out 12a adapted to the flat bottom area and also as a flat one Area executed. The probe 543b, however, has a contact area that corresponds to the radius the recess 12b is adapted.

Die Registerhaltigkeit der Druckplatte 1 wird analog zur Lage im Druckplatten-Magazin 2 gesichert. Das heißt, dass der Führungskörper 542b und der Tastkopf 543b des Pass-Stiftes 54b Kontakt zur Druckplatte 1 in der Aussparung 12b haben muss, während in der Aussparung 12a nur der flache Tastkopf 543a mit deren Grund Kontakt haben darf.The registration of the printing plate 1 becomes analogous to the position in the printing plate magazine 2 secured. That is, the guide body 542b and the probe 543b of the alignment pin 54b must have contact to the pressure plate 1 in the recess 12b, while in the Recess 12a only the flat probe 543a with the base of which may contact.

Zur Wirkungsweise der EinrichtungHow the facility works

Das Druckplatten-Magazin 2 wird mit einer Druckplatte 1 bestückt und aus seiner Ruhestellung in die Stellung zum Druckplatten-Wechsel gefahren. Der Plattenzylinder 4 wird so positioniert, dass eine Konstellation entsteht, die das Einführen einer Druckplatte 1 in die vordere Klemmeinrichtung 5 ermöglicht. Diese Stellung ist in der Figur 1 dargestellt.The printing plate magazine 2 is equipped with a printing plate 1 and from its rest position moved to the position to change the pressure plate. The plate cylinder 4 is positioned that a constellation arises that the insertion of a pressure plate 1 in the front Clamping device 5 enables. This position is shown in Figure 1.

Die Druckplatte 1 ist im Druckplatten-Magazin 2 durch das Vorpass-Stift-System vorpositioniert. Zum Druckplatten-Wechsel wird eine Druckplatte 1 aus dem Druckplatten-Magazin 2 frei gegeben, indem die Vorpass-Stifte 21 a, 21b zurückgezogen werden. Dabei treten Fördereinrichtungen in Kontakt mit der Druckplatte 1. Als Fördereinrichtungen sind im Ausführungsbeispiel Sauger 3 vorgesehen. Es sind aber auch Transportrollen und andere Einrichtungen möglich. Diese erfassen die Druckplatte 1 und fördern sie aus dem Druckplatten-Magazin 2 in Richtung der geöffneten Klemmeinrichtung 5. In dieser Stellung ist die untere Klemmschiene 51 von der oberen Klemmschiene 52 zurückgezogen und befindet sich von der oberen Klemmschiene in der am weitesten entfernten Stellung.The printing plate 1 is pre-positioned in the printing plate magazine 2 by the pre-fitting pen system. To change the printing plate, a printing plate 1 is removed from the printing plate magazine 2 released by withdrawing the pre-fit pins 21 a, 21 b. In doing so, funding agencies come into play in contact with the pressure plate 1. As conveyors are in the embodiment Suction cup 3 provided. But there are also transport rollers and other facilities possible. These capture the printing plate 1 and convey it from the printing plate magazine 2 in the direction of the open clamping device 5. In this position, the lower one Clamping rail 51 withdrawn from the upper clamping rail 52 and is located by the top clamp in the most distant position.

Innerhalb der Klemmeinrichtung 5 wird die Druckplatte 1 mit ihren Ausstanzungen 12a; 12b auf die Pass-Stifte 54a; 54b gefahren. Liegt die Druckplatte 1 in der registergerechten Soll-Lage (siehe Figur 2), ist der Kontakt durch die elektrisch leitende Druckplatte 1 zwischen dem Pass-Stift 54a und dem Pass-Stift 54b geschlossen.Within the clamping device 5, the pressure plate 1 with its punched-out portions 12a; 12b on dowel pins 54a; 54b driven. Is the pressure plate 1 in the register-correct target position (see Figure 2), the contact is through the electrically conductive pressure plate 1 between the dowel pin 54a and the dowel pin 54b closed.

Ist die registergerechte Soll-Lage analog Figur 2 erreicht, wird ein Signal an die Steuerung der Druckmaschine generiert und damit die Klemmeinrichtung 5 geschlossen. Die weiteren Schritte zum Spannen der Druckplatte 1 können nun eingeleitet werden.
