Abstract
Description
Die Erfindung betrifft ein Verfahren zum Vereinzeln von blattartigen, flächigen Elementen, insbesondere von zu belichtenden Druckplatten, von einem Stapel derartiger Elemente, vorzugsweise für ein automatisches Laden eines Druckplattenbelichters.The invention relates to a method for separating sheet-like, sheet-like elements, in particular printing plates to be exposed, from a stack of such elements, preferably for automatically loading a printing platesetter.
Des weiteren betrifft die Erfindung eine Einrichtung zum Vereinzeln von blattartigen, flächigen Elementen, insbesondere von zu belichtenden Druckplatten, von einem Stapel derartiger Elemente, bevorzugt für eine automatische Ladevorrichtung für einen Druckplattenbelichter, mit einem Organ zur Erfassung des im Stapel jeweils oberen bzw. vorderen Elementes wenigstens im Verlauf eines Randes, vorzugsweise zur Durchführung des vorgenannten Verfahrens.Furthermore, the invention relates to a device for separating sheet-like, sheet-like elements, in particular of printing plates to be exposed, from a stack of such elements, preferably for an automatic loading device for a printing platesetter, with an organ for detecting the stack in the upper or front element at least in the course of an edge, preferably for carrying out the aforementioned method.
Insbesondere für das automatische Laden eines Druckplattenbelichters, bevorzugt zur Belichtung von Druckplatten für die Verwendung in einer Offset-Druckmaschine, aber auch in anderen Speicherbereichen, werden blattartige, flächige Elemente in einem Stapel bereitgehalten bzw. bevorratet, sei es flach übereinanderliegend oder aneinanderlehnend und stehend. Unabhängig von der Oberflächenbeschaffenheit kommt es dabei zumeist zu flächigen Anhaftungen aufeinanderfolgender Elemente, wobei die jeweilige Oberflächenbeschaffenheit Anhaftungen oder sogar Verklebungen noch begünstigen kann. Für einen Ladevorgang müssen aber derartige Elemente üblicherweise nacheinander vereinzelt, also jeweils vom Stapel getrennt werden. Dies muß zuverlässig geschehen, sollen nicht im nachfolgenden Arbeitsschritt Störungen auftreten. Für einen automatischen Ladevorgang soll auch die zuverlässige Trennung wie der Ladevorgang selbst vom Automatismus selbst gewährleistet sein, ohne daß eine Überwachung oder ein Eingriff durch eine Bedienungsperson erfolgen muß, wodurch der Automatismus durchbrochen und insgesamt in Frage gestellt würde.In particular, for the automatic loading of a printing platesetter, preferably for the exposure of printing plates for use in an offset printing machine, but also in other storage areas, sheet-like, flat elements are stored in a stack, be it flat overlying or against each other and standing. Irrespective of the surface condition, surface adhesions of successive elements are usually the result, with the respective surface condition still being able to promote adhesions or even adhesions. For a charging process, however, such elements usually have to be singulated one after the other, that is, each time separated from the stack. This must be done reliably, should not occur in the subsequent step faults. For an automatic charging process, the reliable separation, such as the charging process itself, should also be ensured by the automatism itself, without the need for monitoring or intervention by an operator, which would break through the automatism and call it into question altogether.
Diese geforderte Zuverlässigkeit ist insbesondere bei sogenannten Autoloadern für Druckplattenbelichter nicht zufriedenstellend verwirklicht und daher ein Problempunkt.This required reliability is not satisfactorily realized especially in so-called autoloaders for platesetter and therefore a problem.
Der Erfindung liegt die Aufgabe zugrunde, bei einem Verfahren bzw. einer Einrichtung der eingangs genannten Gattung, die Zuverlässigkeit, vorzugsweise kostengünstig und mit relativ einfachen Mitteln bzw. Umbaumaßnahmen, zu verbessern.The invention is based on the object, in a method or a device of the type mentioned, the reliability, preferably inexpensively and with relatively simple means or conversion measures to improve.
Diese Aufgabe wird in Verfahrenshinsicht erfindungsgemäß dadurch gelöst, daß beim Trennen des im Stapel oberen bzw. vorderen Elementes vom Stapel dieses vom Stapel zu trennende Element in einem Randbereich ausgebuchtet, aufgewölbt, ausgebeult oder sonstwie ausgebogen wird.This object is achieved in method according to the invention in that when separating the top of the stack or front element from the stack of this stacked from the stack element in a peripheral area, bulged, bulged or otherwise bent out.
Wesentlich dabei ist, daß im Randverlauf die flächige Anhaftung des abzunehmenden Elementes am nächstfolgenden Element lokal über einen Abschnitt durchbrochen und gelöst wird, so daß sich diese Störung mit Vorteil beim weiteren Abnehmen leicht fortpflanzt. Bei dem Versuch eines gleichmäßigen oder mittigen Erfassens des flächigen Elementes würde sich ein Luftunterdruck ausbilden, der die Anhaftung begünstigt und verstärkt und sich so einem weiteren Abtrennen des Elementes widersetzt. Wird jedoch, wie erfindungsgemäß vorgesehen, der Randverlauf des abzunehmenden Elementes ausgebuchtet, so kommt es zu lokalen Verwerfungen oder Faltenbildungen, die in günstiger Weise die Anhaftungstendenz stören.It is essential that the surface adhesion of the abzunehmenden element on the next element is broken and broken locally over a section in the edge course, so that this disorder easily propagates with advantage in further weight loss. In an attempt to uniformly or centrally detecting the sheet member, an air pressure would form, which promotes the adhesion and reinforced and thus opposes a further separation of the element. However, if, as provided by the invention, the edge contour of the abzunehmenden element bulged, it comes to local distortions or wrinkles, which disturb the tendency to attach in a favorable manner.
Eine Weiterbildung des erfindungsgemäßen Verfahrens sieht vor, daß die Trennung des erfaßten Elementes unterstützt und verstärkt wird, indem von der Stoßkante des ausgebuchteten Randes her Luft zwischen das abzutrennende Element und den Stapel geblasen wird.A development of the method according to the invention provides that the separation of the detected element is supported and reinforced by air is blown between the abzutrennende element and the stack from the abutting edge of the notched edge.
Bevorzugt wird erfindungsgemäß der gesamte Stapel quer zu den Stoßkanten der Elemente belüftet. Die Elemente sind vorzugsweise aneinanderlehnend zu einem Stapel gestellt, wobei die Elemente jeweils an ihrem unteren Rand zum Vereinzeln erfaßt werden und entsprechend bevorzugt auch von unten belüftet werden, indem der Stapel auf einen oder mehrere Lüftungsschlitze gestellt ist.Preferably, according to the invention, the entire stack is ventilated transversely to the abutting edges of the elements. The elements are preferably placed against each other to form a stack, wherein the elements are each detected at its lower edge for separating and are preferably also ventilated from below by the stack is placed on one or more ventilation slots.
Eine erfindungsgemäße Einrichtung der eingangs genannten Gattung zeichnet sich in selbständiger Lösung der gestellten Aufgabe dadurch aus, daß das Erfasungsorgan derart ausgestaltet ist, daß der von ihm erfaßte Randverlauf des erfaßten Elementes wenigstens in einem Abschnitt gewölbt ist. Die sich daraus erfindungsgemäß ergebenden Vorteile sind sinngemäß bereits im Zusammenhang mit dem erfindungsgemäßen Verfahren geschildert worden.An inventive device of the type mentioned is characterized in an independent solution of the problem by the fact that the Erfasungsorgan is designed such that the detected edge of the detected element arched at least in one section. The advantages resulting therefrom according to the invention have already been described analogously in connection with the method according to the invention.
Es sind prinzipiell die verschiedensten Erfassungselemente denkbar, die so angeordnet oder ausgebildet sein könnten, daß die beim erfindungsgemäßen Verfahren entstehende lokale Störung verwirklicht wird. Denkbar sind zum Beispiel häkchenartige Klauen, Klammern, Reibschlußfinger oder-laschen oder dergleichen mehr.In principle, the most diverse detection elements are conceivable, which could be arranged or designed such that the local interference occurring in the method according to the invention is realized. For example, hook-like claws, clamps, frictional fingers or lugs or the like are conceivable.
Häufig werden zum Erfassen und Anheben von blattartigen Elementen Saugelemente vorgesehen, die in verschiedenen Anordnungen oder Anzahlen vorhanden sein könnten. Gerade auch bei Verwendung derartiger Saugelemente kann, wie nach einer Weiterbildung der erfindungsgemäßen Einrichtung vorgesehen, die Erfindung mit einfachen Mitteln und wenigen Veränderungen zuverlässig verwirklicht werden, indem wenigstens eines der Saugelemente weiter von der Oberfläche des anzusaugenden Elementes beabstandet ist als andere der Saugelemente. Bis zu diesem weiter entfernten Saugelement ist der Ansaugweg, der vom Element zurückgelegt wird, größer, so daß sich automatisch an dieser Stelle eine Ausbuchtung oder Auswölbung im Element ergibt, weil das Element an anderen, mehr oder weniger benachbarten Saugelementen eher anschlägt und sich daher gezwungenermaßen durchbiegen muß. Dabei reichen schon einige wenige Millimeter Wegunterschied zumeist aus. Dieser Wegunterschied kann in baulich besonders und überraschend einfacher und kostengünstiger Weise zum Beispiel dadurch erreicht werden, daß bei dem beabstandeteren Saugelement lediglich eine Unterlegscheibe weniger verwendet wird, so daß diese als Distanzstück wegfällt.Often suction elements are provided for detecting and lifting sheet-like elements, which could be present in various arrangements or numbers. Especially when using such suction elements can, as provided according to a development of the device according to the invention, the invention with simple means and few changes reliably be realized by at least one of the suction elements is further spaced from the surface of the element to be sucked than other of the suction elements. Up to this farther suction element, the suction path, which is covered by the element, larger, so that automatically at this point a bulge or bulge in the element results because the element at other, more or less adjacent suction elements rather abuts and therefore forced must bend. It is already sufficient for a few millimeters path difference mostly. This path difference can be achieved in a structurally particularly and surprisingly simple and cost-effective manner, for example, by the fact that only one washer is used less in the spaced-apart suction element, so that it is omitted as a spacer.
Wenigstens ein Luftblasorgan wird erfindungsgemäß bevorzugt dem zu erwartenden Aufwölbungsbereich des zu erfassenden Elementes, also bspw. einem beabstandeteren Saugelement, zugeordnet positioniert. Es können auch weitere Luftblasorgane dort oder im weiteren Umfeld angeordnet werden.At least one air blowing element according to the invention is preferably positioned in relation to the expected bulging region of the element to be detected, that is to say, for example, a spaced-apart suction element. It can also be arranged further air blowing organs there or in the wider environment.
Eine nächste Weiterbildung der Erfindung sieht vor, daß sich das wenigstens eine Luftblasorgan über die gesamte Tiefe des Stapels erstreckt und diesen belüftet und so eine Trennbarkeit der Elemente im gesamten Stapel vorbereitet und unterstützt.A further development of the invention provides that the at least one air blowing element extends over the entire depth of the stack and aerates it and thus prepares and supports a separability of the elements in the entire stack.
Ein Ausführungsbeispiel, aus dem sich weitere erfinderische Merkmale ergeben, auf das die Erfindung in Ihrem Umfang aber nicht beschränkt ist, ist in der Zeichnung dargestellt. Es zeigen schematisch:
- Fig. 1
- eine Unteransicht eines Stapels aus Druckplatten mit einem Erfassungsorgan und
- Fig. 2
- einen Schnitt durch den Stapel gemäß Fig. 1 entlang der in Fig. 1 mit II - II bezeichneten strichpunktierten Linie.
- Fig. 1
- a bottom view of a stack of printing plates with a detecting member and
- Fig. 2
- a section through the stack of FIG. 1 along the dot-dash line indicated in Fig. 1 II - II.
Die Figuren 1 und 2 zeigen schematisch, nicht maßstabsgerecht und nur beispielhaft einmal in Fig. 1 eine Unteransicht mit Blick gemäß der in Fig. 2 mit I - I bezeichneten strichpunktierten Linie und einmal in Fig. 2 eine Schnittansicht entlang der in Fig. 1 mit II - II bezeichneten strichpunktierten Linie eines Stapels aus zu belichtenden Druckplatten 1,1'. Die mit 1' bezeichnete Druckplatte ist jeweils die obere bzw. in dem stehenden Stapel die vordere Platte des Stapels, die zu Beginn ihres Vereinzelungsvorganges bei ihrer Abnahme und Lösung vom Stapel dargestellt ist.Figures 1 and 2 show schematically, not to scale and only by way of example once in Fig. 1 is a bottom view with a view according to the in Fig. 2 with I - I designated dash-dotted line and once in Fig. 2 is a sectional view taken along in FIG II - II designated dot-dash line of a stack of printing plates to be exposed 1,1 '. The pressure plate designated by 1 'is in each case the upper or in the stationary stack, the front plate of the stack, which is shown at the beginning of their separation process in their acceptance and solution from the stack.
Für die Vereinzelung und Erfassung der Druckplatte ist ein Erfassungsorgan 2 vorgesehen, das Bestandteil einer nicht näher dargestellten Ladeeinrichtung eines ebenfalls nicht dargestellten Druckplattenbelichters sein kann. Das Erfassungsorgan 2 besteht im wesentlichen aus einer Leiste 3, die schwenkbeweglich um eine zu ihrer Erstreckung verlaufende Schwenkachse angeordnet sein kann, um durch eine Schwenkbewegung das Abnehmen der vorderen Druckplatte 1', welches in der Fig. 2 im unteren Bereich der Druckplatte 1 ' gerade erst begonnen hat, in gleicher Richtung fortzuführen, bis die Druckplatte 1' bspw. etwa waagerecht vor dem Stapel in einen Belichter einführbar ist. An der Leiste 3 sind Saugelemente 4, 5 angeordnet, wobei von den Druckplatten 1, 1' und der Leiste 3 in der Fig. 1 nur ein abgebrochener Abschnitt dargestellt ist und entsprechend nur einige Saugelemente 4, 5 dargestellt sind. Durch die Saugelemente 4, 5 wird zur Ansaugung der Druckplatte 1 ' Luft angesaugt und durch angedeutete Schläuche 6 oder dergleichen zu einer nicht dargestellten Pumpeirichtung in Richtung der Pfeile 7 abgeführt. Die Saugelemente 4 sind mit angedeuteten Schraubverbindungen 8 und Unterlegscheiben 9 an der Leiste 3 angeordnet. An den Saugelementen 5 sind die Unterlegscheiben 9 fortgelassen, so daß sie näher an der Leiste 3 angeordnet sind und weiter vom Stapel der Druckplatten 1, 1 ' beabstandet sind.For the separation and detection of the pressure plate, a
Wie insbesondere Fig. 1 zeigt, führt dies auf dem Abschnitt der Druckplatte 1', der von den Saugelementen 5 erfaßt wird, zu einer Auswölbung 10, durch die sich in diesem Abschnitt der Bereich der Druckplatte 1 ' von der gestrichelt dargestellten Fluchtlinie 11 der übrigen Bereiche der Druckplatte 1 ' entfernt. In die Auswölbung 10 kann somit Luft eintreten, die ein Ablösen der Druckplatte 1 ' vom Stapel begünstigt.As shown in particular Fig. 1, this leads to the portion of the pressure plate 1 ', which is detected by the
