The apparatus is especially suitable for the sorting of so-called flexo plates and flexible offset plates. <IMAGE>

Description

Die Erfindung betrifft eine Sortiereinrichtung nach dem Ober­begriff des unabhängigen Patentanspruchs 1.The invention relates to a sorting device according to the preamble of independent claim 1.

Die Sortiereinrichtung ist insbesondere für einen Platten­transporteur für Druckplatten gemäss der schweizerischen Pa­tentanmeldung 1303/88 vorgesehen. Mit einem solchen Platten­transporteur werden flexible Druckplatten von den diese Platten hergestellten Maschinen zu den Falzapparaten im Rotationsraum transportiert. Die Druckplatten werden hier­bei hängend an einem in einer Schiene geführten Förderorgan zu einer Entladestation gefördert und dort einem Auffang­behälter zugeführt. Die Druckplatten sind insbesondere flexible Druckplatten, sogenannte Flexoplatten, die sehr empfindlich sind und sorgfältig behandelt werden müssen. Die Druckplatten können jedoch auch Offsetplatten sein. Denkbar ist auch ein Transport und eine Sortierung von ande­ren flächigen Produkten.The sorting device is intended in particular for a plate transporter for printing plates in accordance with Swiss patent application 1303/88. With such a plate transporter, flexible printing plates are transported from the machines produced by these plates to the folders in the rotation area. The printing plates are suspended from a conveyor in a rail and conveyed to an unloading station, where they are fed to a collecting container. The printing plates are in particular flexible printing plates, so-called flexo plates, which are very sensitive and must be handled with care. However, the printing plates can also be offset plates. Transport and sorting of other flat products is also conceivable.

Der Erfindung liegt nun die Aufgabe zugrunde, eine Sortier­einrichtung der genannten Gattung zu schaffen, mit der selbsttätig mehrere Druckplatten, beispielsweise vierzig und mehr Druckplatten, insbesondere flexible Druckplatten mit hoher Betriebssicherheit einzeln zur Entnahme sortiert abgelegt werden können. Die Sortiereinrichtung soll trotz­dem vergleichsweise wenig Platz beanspruchen und eine Be­schädigung empfindlicher Druckplatten vermieden werden.The invention is based on the object of creating a sorting device of the type mentioned, with which a plurality of printing plates, for example forty or more printing plates, in particular flexible printing plates with a high level of operational reliability, can be stored individually sorted for removal. The sorting device should nevertheless take up comparatively little space and avoid damaging sensitive printing plates.

Die Aufgabe wird durch die Erfindung gemäss Anspruch 1 ge­löst. Die in die Sortiereinrichtung abgegebenen Druckpro­dukte können stehend vertikal von oben nach unten in die Fächer gefördert werden, wobei sie auf ihrem Förderweg nie stillstehen und damit eine sehr schnelle Beschickung der Fächer möglich ist. Wesentlich ist, dass die Fächer in freier Reihenfolge beschickt werden können, d.h. es kann in jedem Fall das oberste leere Fach berücksichtigt werden. Der Förderweg der Druckplatten kann somit optimal kurz gehalten werden. Es können auch zwei und mehr Druckplatten in einem Fach abgelegt werden. Dies ergibt dann eine Ver­doppelung der Anzahl lagerbarer Druckplatten.The object is achieved by the invention according to claim 1. The printed products discharged into the sorting device can be conveyed vertically from top to bottom into the compartments, whereby they never stand still on their conveying path and therefore very quick loading of the compartments is possible. It is essential that the subjects can be loaded in free order, i.e. in any case, the top empty compartment can be taken into account. The delivery path of the printing plates can thus be kept optimally short. Two or more printing plates can also be stored in one compartment. This then doubles the number of storable printing plates.

Nach einer Weiterbildung weist die zur Förderung der Druck­platten vorgesehene Transportvorrichtung wenigstens eine Führungsschiene mit Vakuumöffnungen auf, an welche die stehend bewegten Druckplatten mit geringem Druck gezogen werden, was eine die Druckplatten besonders schonende Be­handlung und sichere Beschickung der Fächer ermöglicht.According to a development, the transport device provided for conveying the printing plates has at least one guide rail with vacuum openings to which the upright moving printing plates can be pulled with low pressure, which enables the printing plates to be treated particularly gently and to load the compartments safely.

Der Abstand zwischen den Tablaren kann optimal kurz gewählt werden, wenn der Sortierwagen Mittel aufweist, mit denen beim gewählten Fach das obere Tablar verschwenkt und dadurch die Einführöffnung vergrössert wird.The distance between the trays can be selected to be optimally short if the sorting trolley has means with which the upper tray in the selected compartment is pivoted and the insertion opening is thereby enlarged.

Ausführungsbeispiele der Erfindung werden nachfolgend anhand der Zeichnung näher erläutert. Es zeigen:

Exemplary embodiments of the invention are explained in more detail below with reference to the drawing. Show it:
  • 1a is a schematic view of the sorting device,
  • 1b is a partial view of the transport device for conveying the printing plates,
  • 2a-2c partial views of the sorting device,

  • Fig. 4 shows a further embodiment of the sorting device, parts which are not essential to the invention being omitted for reasons of illustration.

An einem Gestell 30 sind mehrere Tablare oder Fächer 3 über­einander angeordnet, die geneigt und parallel zueinander sind. Jedes Fach 3 ist oben über eine Einführöffnung 31 zu­gänglich und kann unten über eine Entnahmeöffnung 32 geleert werden. Der Abstand zwischen zwei Fächern 3 ist so gewählt, dass darin wenigstens eine Druckplatte 1 eingelagert werden kann. Mit einer weiter unten näher erläuterten Transportvor­richtung 6 werden die Druckplatten 1 von oben nach unten an Oeffnungen 31 entlang bewegt.On a frame 30, several trays or compartments 3 are arranged one above the other, which are inclined and parallel to one another. Each compartment 3 is accessible at the top via an insertion opening 31 and can be emptied at the bottom via a removal opening 32. The distance between two compartments 3 is selected so that at least one pressure plate 1 can be stored therein. With a transport device 6 explained in more detail below, the printing plates 1 are moved along openings 31 from top to bottom.

Zwischen den Fächern 3 und der Transportvorrichtung 6 ist wenigstens ein Sortierwagen 2 angeordnet, der mit einem von einem Motor 7 angetriebenen Antriebsorgan 5 nach oben und nach unten bewegt werden kann. Mit einer hier nicht gezeig­ten Steuervorrichtung kann der Sortierwagen 2 zu einem ge­wünschten Fach 3 bewegt werden. Sind viele, beispielsweise fünfundvierzig Fächer 3 vorhanden, sind vorzugsweise mehrere Sortierwagen 2 vorgesehen. Beispielsweise sind bei der Aus­führung nach Fig. 4 drei Sortierwagen vorgesehen. Diese sind fest untereinander verbunden und jeder Sortierwagen bedient eine Anzahl Fächer, beispielsweise der oberste Sor­tierwagen fünfzehn Fächer und der zweite Sortierwagen die nachfolgenden fünfzehn Fächer. Die untersten fünfzehn Fächer werden entsprechend durch den untersten Sortierwagen bedient. Dies ist bei beiden Ausführungsbeispielen möglich.At least one sorting carriage 2 is arranged between the compartments 3 and the transport device 6 and can be moved up and down with a drive element 5 driven by a motor 7. With a control device, not shown here, the sorting trolley 2 can be moved to a desired compartment 3. If there are many, for example forty-five compartments 3, several sorting trolleys 2 are preferably provided. For example, three sorting trolleys are provided in the embodiment according to FIG. 4. These are firmly connected to each other and each sorting trolley serves a number of compartments, for example the top sorting trolley fifteen compartments and the second sorting trolley the following fifteen compartments. The bottom fifteen compartments are served accordingly by the bottom sorting trolley. This is possible in both exemplary embodiments.

Der Sortierwagen 2 ist mit einer Klappe 2′ ausgerüstet, die in zwei Stellungen geschaltet werden kann. In der einen, hier gezeigten Stellung wird eine von oben nach unten bewegte Druckplatte 1 von der Transportvorrichtung 6 abgelöst und in das angesteuerte Fach 3 geleitet. Wie die Fig. 1b deutlich zeigt, stehen die Druckplatten 1 nach oben heraushebbar auf Plattenhaltern 22, die an Taktketten 21 befestigt sind. Die Klappe 2′ greift mit ihrem oberen Rand in der gezeigten Stellung hinter die Druckplatte 1. Damit die Druckplatte 1 bei ihrem Transport nach unten vertikal steht und oben nicht nach vorne fällt, weisen die Führungsschienen 51 Oeffnungen 52 auf, die mit einer Vakuumpumpe 7 verbunden sind. Neben den in einer Reihe angeordneten Oeffnungen 52 laufen mit der Ge­schwindigkeit der Taktketten 21 geführte Bänder 24, zwischen denen die Oeffnungen 23 freiliegen. Wird die Vakuumpumpe 7 in Betrieb gesetzt, so werden die Druckplatten 1 flächig an die Bänder 24 gepresst. So können die Druckplatten 1 ohne Reibung an den Führungsschienen 51 entlang nach unten bewegt werden.The sorting trolley 2 is equipped with a flap 2 ', which can be switched in two positions. In the one position shown here, a pressure plate 1 moved from top to bottom is detached from the transport device 6 and guided into the controlled compartment 3. As FIG. 1b clearly shows, the pressure plates 1 can be lifted out upwards on plate holders 22 which are fastened to cycle chains 21. The flap 2 'engages with its upper edge in the position shown behind the pressure plate 1. So that the pressure plate 1 is vertical during transport downwards and does not fall forward at the top, the guide rails 51 have openings 52 which are connected to a vacuum pump 7 are. In addition to the openings 52 arranged in a row, belts 24 run at the speed of the clock chains 21, between which the openings 23 are exposed. If the vacuum pump 7 is put into operation, the pressure plates 1 are pressed flat against the belts 24. The pressure plates 1 can thus be moved down along the guide rails 51 without friction.

Sobald eine Druckplatte 1 mit ihrem unteren Rand auf der Klappe 2′ auftritt, wird sie aus den Plattenhaltern 22 herausgehoben und wie in Fig. 1a gezeigt, in das vorgesehene Fach 3 umgelenkt und hierbei von den Bändern 24 abge­zogen. Etwa gleichzeitig wird die entsprechende Einführ­ öffnung 31 wie in den Fig. 2a - 2c gezeigt vergrössert. Hier­zu ist jedes Fach 3 an seinem unteren Rand mittels Lager­zapfen 14 in Ausnehmungen 26 eines Trägers 27 verschwenkbar gelagert. Am oberen Rand sind jeweils ebenfalls zwei seit­lich vorstehende Zapfen 13 angebracht, die in Ausnehmungen 28 an weiteren Trägern 29 aufliegen. Der Sortierwagen 2 bzw. jeder Sortierwagen weist an einer Platte 11 einen oder mehrere Stössel 10 auf, die frontseitig mit einem Fach B, das über dem zu belegenden Fach A liegt, kurz vor dem Ein­legen der Druckplatte 1 verschwenkt wird. Hierbei stösst das Fach B mit an diesem angebrachten Distanzstücken 16 an einem Fach D an, das ebenfalls, aber um einen kleineren Winkel verschwenkt wird. Das nachfolgende Fach D wird in der Regel hingegen nicht mehr verschwenkt. Der Stössel 10 wird beispielsweise mit einem pneumatischen Druckzylinder 9 betätigt. Sobald die Druckplatte 1 in das Fach 3 eingelegt ist, fährt der Stössel 10 in die Grundstellung zurück und die Fächer A bis C fallen durch ihr Eigengewicht ebenfalls in ihre Grundstellung zurück. Der Sortierwagen 2 kann nun an ein anderes, leeres Fach bewegt werden. Diese Erweiterung der Einführöffnung erlaubt es, die Fächer 3 mit vergleichs­weise kurzen Abständen zueinander und damit platzsparend an­zuordnen und dennoch die Druckplatten 1 mit geringer oder im Fall von Offsetplatten ohne Durchbiegung in ein Fach 3 einzuleiten. Zudem ist es möglich, Ränder 17 und 18 anzu­bringen, die das Fach 3 versteifen und zudem ein Verstauben der abgelagerten Druckplatten 1 zu verringern. Zur Erleichte­rung der Entnahme der Druckplatten 1 weist jedes Fach 3 am unteren Rand Ausnehmungen 20 auf. Die ebenfalls am unteren Rand vorgesehenen abgewinkelten Ränder 19 verhindern ein Herausfallen der Druckplatten 1.As soon as a pressure plate 1 occurs with its lower edge on the flap 2 ', it is lifted out of the plate holder 22 and, as shown in Fig. Around the same time, the corresponding introductory opening 31 as shown in FIGS. 2a-2c enlarged. For this purpose, each compartment 3 is pivotally mounted on its lower edge by means of bearing pins 14 in recesses 26 of a carrier 27. Two laterally projecting pins 13 are also attached to the upper edge and rest in recesses 28 on further supports 29. The sorting trolley 2 or each sorting trolley has one or more plungers 10 on a plate 11, which is pivoted at the front with a compartment B, which lies above the compartment A to be occupied, shortly before the printing plate 1 is inserted. Here, the compartment B with spacers 16 attached to it abuts a compartment D, which is also pivoted, but by a smaller angle. The following compartment D, on the other hand, is generally no longer pivoted. The plunger 10 is actuated, for example, with a pneumatic pressure cylinder 9. As soon as the pressure plate 1 is inserted into the compartment 3, the tappet 10 moves back into the basic position and the compartments A to C also fall back into their basic position due to their own weight. The sorting trolley 2 can now be moved to another, empty compartment. This expansion of the insertion opening allows the compartments 3 to be arranged at comparatively short distances from one another and thus in a space-saving manner, and yet the printing plates 1 are introduced into a compartment 3 with little or, in the case of offset plates, no deflection. It is also possible to attach edges 17 and 18 that stiffen the compartment 3 and also dust to reduce the deposited printing plates 1. To facilitate the removal of the printing plates 1, each compartment 3 has recesses 20 at the lower edge. The angled edges 19 also provided at the lower edge prevent the printing plates 1 from falling out.

Fällt die Funktion der Sortiereinrichtung durch einen pneu­matischen oder elektronischen Fehler aus, so werden die Klappen 2′ automatisch auf Durchlauf gestellt und die Druck­platten 1 werden durch ein festes Umlenkblech 31 in einen Ueberlaufbehälter 4 geleitet.If the function of the sorting device fails due to a pneumatic or electronic error, the flaps 2 'are automatically set to run and the pressure plates 1 are passed through a fixed deflector plate 31 into an overflow tank 4.

Bei der in Fig. 4 gezeigten Ausführung werden die Druckplat­ten 1 in Fächer 56 eingelagert. Durch elektronisch gesteuerte Vorwahl wird für jede Druckplatte ein Fach 56 vorbestimmt. Die Elektronik erkennt freie Fächer 56 und ordnet die Druck­platten 1 diesen zu. Auf einem Bildschirm 57 ist sichtbar, in welchem der Fächer 56 sich welche Druckplatte 1 befindet. Dadurch ist es möglich, vor Beginn des Andruckes am jeweili­gen Falzapparat die Druckplatten 1 sortiert einzulagern.In the embodiment shown in FIG. 4, the printing plates 1 are stored in compartments 56. A compartment 56 is predetermined for each printing plate by electronically controlled preselection. The electronics recognize free compartments 56 and assign the printing plates 1 to them. A screen 57 shows in which of the compartments 56 which printing plate 1 is located. This makes it possible to store the printing plates 1 sorted on the respective folder before the start of pressure.

Wie die Fig. 4 zeigt, ist die Sortiereinrichtung mit drei Sortierwagen 70 bestückt, die an einer Führung 71 geführt sind und die jeweils fünzehn Fächer 56 bedienen. Die Sortier­wagen sind untereinander fest verbunden und haben einen fixen Abstand zueinander. Jeder Sortierwagen 70 ist mit einer Klappe 54 ausgerüstet, die in zwei Stellungen geschal­tet werden kann. In der Arbeitsstellung ist die Klappe 54 eingeschwenkt und hebt die ankommende Druckplatte 1 aus den Plattenhaltern 53, die mittels einer Transportvorrichtung 50 bewegt und an einer endlosen Antriebskette 72 angebracht sind. In der anderen Stellung ist die Klappe 54 ausge­schwenkt und lässt die Druckplatte 1 passieren. Dies ist dann der Fall, wenn einer der drei Sortierwagen 70 bei einem bereits belegten Fach 56 steht oder eine nicht identifizierte Druckplatte 1 in einen Ueberlaufbehälter 73 geleitet werden muss. Die Antriebsketten 72 laufen in Führungsschienen 51, die frontseitig Düsenöffnungen 52 besitzen. Durch einen Un­terdruck in den Führungsschienen 51 werden die Druckplatten 1 an die Schienen 51 gezogen und dadurch die Druckplatten 1 in vertikaler Lage gehalten. Da die Druckplatten 1 durch die gefalzten Ränder vergleichsweise steif sind, genügt ein geringer Druck auf die Druckplatten 1. Der Durchlauf einer Druckplatte 1 wird mit ein Spiegelband 74 aufweisenden Licht­schranken 75 erfasst. Mit weiteren Lichtschranken 76 und 77 wird der Einlauf der Druckplatten 1 in die Fächer 56 erkannt und wird festgestellt, welche Fächer 56 belegt bzw. frei sind.As shown in FIG. 4, the sorting device is equipped with three sorting trolleys 70 which are guided on a guide 71 and which operate fifteen compartments 56 in each case. The sorting trolleys are firmly connected to each other and have a fixed distance from each other. Each sorting cart 70 is with a flap 54 equipped, which can be switched in two positions. In the working position, the flap 54 is pivoted in and lifts the incoming pressure plate 1 out of the plate holders 53, which are moved by means of a transport device 50 and are attached to an endless drive chain 72. In the other position, the flap 54 is pivoted out and allows the pressure plate 1 to pass. This is the case when one of the three sorting wagons 70 is standing next to a compartment 56 that is already occupied or an unidentified printing plate 1 has to be directed into an overflow container 73. The drive chains 72 run in guide rails 51 which have nozzle openings 52 on the front. A negative pressure in the guide rails 51 pulls the pressure plates 1 onto the rails 51, thereby holding the pressure plates 1 in a vertical position. Since the pressure plates 1 are comparatively stiff due to the folded edges, a slight pressure on the pressure plates 1 is sufficient. The passage of a pressure plate 1 is detected with light barriers 75 having a mirror band 74. With further light barriers 76 and 77, the entry of the printing plates 1 into the compartments 56 is recognized and it is determined which compartments 56 are occupied or free.

Die Druckplatten 1 sind bei diesem Ausführungsbeispiel fle­xible Kunststoffolien, die unter der Bezeichnung "Flexo­platten" bekannt sind. Die Antriebsketten 72 und die Füh­ rungsschienen 51 können bei dieser Ausführung auch wie in Fig. 1b gezeigt ausgebildet sein. Ebenfalls können hier die Tablare verschwenkbar ausgebildet sein und die Sortier­wagen 70 eine Vorrichtung zum Verschwenken dieser Tablare aufweisen. Anderseits ist bei der Ausführung nach den Fig. 1 bis 3 eine die elektronische Erkennung mit Lichtschranken 74 - 77 und ein Bildschirm 54 ebenfalls vorgesehen.In this exemplary embodiment, the printing plates 1 are flexible plastic films which are known under the name “flexo plates”. The drive chains 72 and the Füh approximately rails 51 can also be formed in this embodiment as shown in Fig. 1b. The trays can also be designed to be pivotable here and the sorting trolleys 70 have a device for pivoting these trays. On the other hand, in the embodiment according to FIGS. 1 to 3, electronic detection with light barriers 74-77 and a screen 54 are also provided.
