Description

Die Erfindung betrifft ein Verfahren zum Verbinden der freien Enden des flexiblen Transportbandes eines Bän­ dertischs für Bogen verarbeitende Maschinen, wobei das Transportband quer zu seiner Ebene durchgehende Saug­ luftlöcher aufweist, die nach einem bestimmten Ver­ teilungsmuster angeordnet sind, das sich gleichmäßig nebeneinanderliegend über die gesamte Transportband­ längevielfach wiederholt, mit sich in Längsrichtung des Transportbandes erstreckenden, zu den Transportband­ enden hin auslaufenden, keilartigen Anschrägungen, die sich überlappend aufeinanderliegend zur normalen Trans­ portbanddicke ergänzen und in der sich überlappend auf­ einanderliegenden Position mittels einer Verbindungs­ vorrichtung zu einem Endlosband fest miteinander ver­ bindbar sind.The invention relates to a method for connecting the free ends of the flexible conveyor belt of a bank dertischs for sheet-processing machines, whereby the Conveyor belt continuous suction across its plane has air holes that according to a certain Ver Partition pattern are arranged that are even side by side over the entire conveyor belt repeated many times, with itself in the longitudinal direction of the Conveyor belt extending to the conveyor belt tapered, wedge-like bevels that end overlapping one another to the normal trans portband thickness complement and in the overlapping on opposite position by means of a connection device to form an endless belt are binding.

Bei derartigen Verfahren ist es bekannt, daß die Trans­ portbänder in ein Unterteil einer Klebepresse einge­ führt und ausgerichtet werden, um nach Aufbringen einer Klebeflüssigkeit auf die aufeinanderzulegenden An­ schrägungen der Transportbandenden durch ein Oberteil der Klebepresse fest aufeinander gepreßt zu werden.In such processes, it is known that the Trans port tapes inserted into a lower part of an adhesive press leads and aligned to after applying one Adhesive liquid on the to be stacked Bevels of the conveyor belt ends through an upper part the glue press to be pressed tightly together.

Nach dem Lösen aus der Klebepresse wird das nunmehr end­ lose Transportband von der Seite her auf den Bändertisch aufgeschoben. Dazu sind alle an einer Seite des Bänder­ tischs angeordneten Antriebs-, Lager- und Standvorrich­ tungen abzubauen, damit das Transportband ungehindert auf den Bändertisch aufgeschoben werden kann.After releasing it from the glue press, this will now end loose conveyor belt from the side onto the belt table postponed. To do this, everyone is on one side of the tapes tables arranged drive, storage and stand device dismantling, so that the conveyor belt unhindered can be pushed onto the conveyor table.

Dies ist sowohl bei einer Neumontage eines Bändertisches als auch bei einem Austausch eines defekten Transport­ bandes erforderlich.This is both when reassembling a conveyor table as well as when replacing a defective transport bandes required.

Aufgabe der Erfindung ist es daher mit einfachen Mitteln und geringem Arbeitsaufwandt eine Montage von Transport­ bändern auf einen Bändertisch zu ermöglichen. The object of the invention is therefore with simple means and low workload an assembly of transport to allow tapes on a conveyor table.  

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das mit den keilartigen Anschrägungen an seinen freien Enden versehene Transportband in Transport­ richtung um den Bändertisch und gegebenenfalls eine Spannrolle geführt wird, daß die freien Enden des Transportbandes sich überlappend in der Verbindungs­ vorrichtung angeordnet werden und daß die freien Enden des Transportbandes mittels der Verbindungsvor­ richtung zu einem Endlosband fest miteinander verbunden werden. Auf diese Weise wird sowohl die Neubestückung als auch der Austausch von Transportbändern eines Bän­ dertischs an den fertig montierten Bändertisch vorge­ nommen. Dies hat den Vorteil, daß dieser Vorgang nicht an einem durch die demontierten Teile in seiner Stabi­ lität beeinträchtigten Bändertisch erfolgen muß und die sonst leicht möglichen Beschädigungen vermieden werden.According to the invention, this object is achieved by that with the wedge-like bevels on his Free-end conveyor belt in transport direction around the conveyor table and, if necessary, one Tension roller is guided that the free ends of the Conveyor belt overlapping in the connection device are arranged and that the free Ends of the conveyor belt by means of the connection direction to an endless belt firmly connected will. In this way, both the replenishment as well as the exchange of conveyor belts of a band on the fully assembled conveyor table taken. This has the advantage that this process is not on one by the dismantled parts in its stabilizer lity impaired conveyor table must take place and the otherwise easily possible damage avoided will.

Bei dem Austausch eines Transportbandes wird zusätz­ lich eine lange Stillstandzeit und damit Betriebsaus­ fall des Bändertisches vermieden, da keine Demontage- und Montagearbeit anfällt.When replacing a conveyor belt, additional long downtimes and thus business outages Avoid falling of the conveyor table, since no disassembly and assembly work.

Die Verbindung der Transportbandenden ist mit einer Verbindungsvorrichtung nach dem Oberbegriff des An­ spruchs 2 dadurch auf einfache Weise möglich, daß eine Auflageebene wenigstens einen von der Auflage­ ebene rechtwinklig hervorstehenden Justierzapfen auf­ weist, dessen bzw. deren Durchmesser etwa dem Durch­ messer der Saugluftlöcher entspricht und auf den bzw. die die beiden sich überlappenden Enden des TRansport­ bandes mit zueinander fluchtend angeordneten Saugluft­ löcher aufsetzbar und miteinander verbindbar sind. Damit erfolgt allein durch das Aufsetzen der Transport­ bandenden mit ihren Saugluftlöchern auf den Justier­ zapfen sowohl in Längsrichtung als auch in Querrichtung eine Justierung der Transportbandenden zueinander. The connection of the conveyor belt ends is with a Connection device according to the preamble of the An saying 2 possible in a simple manner that a support level at least one of the support on the alignment pin projecting at right angles has, whose diameter approximately the through corresponds to the suction air holes and on the or the two overlapping ends of the TRansport bandes with suction air aligned with each other holes can be placed and connected to each other. This is done simply by putting on the transport tape ends with their suction air holes on the adjustment journal in both the longitudinal and transverse directions an adjustment of the conveyor belt ends to each other.  

Gleichzeitig werden die noch nicht miteinander ver­ bundenen Transportbandenden durch den Justierzapfen gehalten, wodurch der nachfolgende Verbindungsvor­ gang, der z.B. ein Klebevorgang oder ein Schweißvor­ gang sein kann, leicht durchführbar ist.At the same time, they are not yet linked together bound conveyor belt ends through the adjusting pin held, causing the subsequent connection gang, e.g. a gluing process or a welding process gear can be easily carried out.

Werden mehrere Saugluftbänder für den gleichen Bänder­ tisch hergestellt, so ist die Länge aller Saugluft­ bänder immer gleich.Be multiple suction bands for the same bands table, so is the length of all suction air tapes always the same.

Bei mehreren Justierzapfen sind diese im gleichen Ver­ teilungsmuster wie die Saugluftlöcher zueinander ange­ ordnet.If there are several adjustment pins, they are in the same ver Patterns like the suction air holes to each other arranges.

Besonders vorteilhaft ist es dabei, wenn in dem Über­ lappungsbereich der Transportbandenden das Verteilungs­ muster der Justierzapfen vollständig dem Verteilungs­ muster der Saugluftlöcher entspricht. Dadurch wird ver­ mieden, daß sich die Saugluftlöcher während des Ver­ bindungsvorganges durch fliesendes Material beim Schweißen oder durch Kleber beim Kleben zusetzen können. Ein anschließendes Wiederherstellen der zugesetzten Saugluftlöcher entfällt.It is particularly advantageous if in the over lapping area of the conveyor belt ends the distribution pattern of the adjustment pin completely the distribution pattern of the suction air holes corresponds. This ver avoided that the suction air holes during the Ver binding process by flowing material at Can weld or clog when gluing. A subsequent restoration of the added There are no suction air holes.

Im Bereich der Justierzapfen kann eine Preßplatte auf die Auflageebene preßbar angeordnet sein, durch die bei dem Verbindungsvorgang die zwischen Auflageebene und Preßplatte angeordneten Transportbandenden aufeinander gepreßt werden.A press plate can be placed in the area of the adjustment pins the support plane can be arranged so that it can be pressed the connection process between the support level and Press plate arranged conveyor belt ends on top of each other be pressed.

Um eine Behinderung der Preßplatte durch die Justier­ zapfen zu vermeiden, kann die Preßplatte zur Auflage­ ebene hin offene Ausnehmungen aufweisen, in die die Justierzapfen einführbar sind.In order to obstruct the press plate by the adjustment To avoid spigots, the press plate can be used as a support Have level open recesses into which the Adjustment pins are insertable.

Sind dabei die Ausnehmungen im gleichen Verteilungsmuster wie die Justierzapfen angeordnet, so bilden die Aus­ nehmungen und Justierzapfen gleichzeitig eine Führung für die Preßplatte. Are the recesses in the same distribution pattern arranged like the adjustment pins, so form the off Guides and adjustment pins at the same time for the press plate.  

Ein Heißverschweißen oder Heißverkleben der Transport­ bandenden ist auf einfache Weise dadurch möglich, daß die Preßplatte und/oder die Auflageebene beheizbar ist. Ein solches Verfahren hat den Vorteil, daß eine homogene Verbindung hoher Stabilität und Belastbarkeit entsteht, die die Standzeit des Transportbandes erheblich er­ höht.A heat seal or hot glue the transport band ends is easily possible in that the press plate and / or the support plane can be heated. Such a method has the advantage that it is homogeneous Connection of high stability and resilience arises, which significantly increases the service life of the conveyor belt increases.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher be­ schrieben.An embodiment of the invention is in the Drawing is shown and will be closer in the following wrote.

Die in den Fig. 1 bis 4 dargestellte Verbindungsvor­ richtung besitzt eine Auflageebene 1, an der nach einem bestimmtenVerteilungsmuster angeordnet zylindrische Justierzapfen 2 rechtwinklig hervorstehen. Eine Preß­ platte 3, die nach dem gleichen Verteilungsmuster wie die Justierzapfen 2 durchgehende Ausnehmungen 4 besitzt, ist derart auf die Auflageebene 1 preßbar, daß die Justierzapfen 2 in die Ausnehmungen 4 hineinragen. Die beiden freien Enden eines flexiblen Transportbandes 5 sind gegenläufig derart mit keilartigen Anschrägungen 6 ausgebildet, daß sie bei sich überlappendem Aufein­ anderliegen zur normalen Transportbandstärke sich er­ gänzen. The connection device shown in Figs. 1 to 4 has a support plane 1 , on which arranged according to a certain distribution pattern, cylindrical adjusting pins 2 protrude at right angles. A press plate 3 , which has continuous recesses 4 according to the same distribution pattern as the adjusting pin 2 , can be pressed onto the support plane 1 in such a way that the adjusting pin 2 protrude into the recesses 4 . The two free ends of a flexible conveyor belt 5 are designed in opposite directions with wedge-like bevels 6 that they overlap with each other to overlap the normal conveyor belt thickness.

Weiterhin ist das Transportband 5 über seine ganze Länge mit Saugluftlöchern 7 versehen, die nach dem gleichen Verteilungsmuster wie die Justierzapfen 2 der Auflageebene 1 angeordnet sind. Die Saugluft­ löcher 7 sind quer zur Ebene des Transportbandes 5 durchgehend ausgebildet und besitzen auch den etwa gleichen Durchmesser wie die Justierzapfen 2.Furthermore, the conveyor belt 5 is provided over its entire length with suction air holes 7 , which are arranged according to the same distribution pattern as the adjusting pins 2 of the support level 1 . The suction air holes 7 are formed transversely to the level of the conveyor belt 5 and also have about the same diameter as the adjusting pin 2nd

Um die zwei freien Enden des Transportbandes 5 zu einem Endlosband zu verbinden, werden diese Enden entsprechend Fig. 1 mit ihren Saugluftlöchern 7 auf die Justierzapfen 2 der Auflageebene 1 aufge­ schoben und zwar derart, daß die Anschrägungen 6 sich überlappend aufeinanderliegen und sich zur normalen Transportbanddicke ergänzen.In order to connect the two free ends of the conveyor belt 5 to form an endless belt, these ends are pushed up according to FIG. 1 with their suction air holes 7 onto the adjusting pins 2 of the support plane 1 in such a way that the bevels 6 overlap one another and become the normal conveyor belt thickness complete.

Anschließend wird die Preßplatte 3 auf die Justier­ zapfen 2 aufgeschoben und mit hoher Kraft gegen die Auflageebene 1 gepreßt, wobei das sich zwischen Preßplatte 3 und Auflageebene 1 befindliche Trans­ portband 5 zusammengepreßt und dessen beide Enden miteinander verbunden werden.Then the press plate 3 is pushed onto the adjustment pin 2 and pressed with high force against the support level 1 , the trans port belt 5 located between the press plate 3 and support level 1 being compressed and the two ends of which are connected to one another.

Außer dem Preßdruck wird die Verbindung noch durch einen vorher auf die sich überlappenden Flächen 8 der Transportbandenden aufgebrachten Kleber oder durch die Beheizung der Preßplatte 3 und/oder Auf­ lageebene 1 und damit heiß Verschweißen bewirkt. Es kann auch nach aufgetragenem Kleber durch Be­ heizen der Verbindungsvorrichtung ein Heißverkleben der Transportbandenden erfolgen.In addition to the pressing pressure, the connection is also brought about by an adhesive previously applied to the overlapping surfaces 8 of the conveyor belt ends or by the heating of the pressing plate 3 and / or on layer 1 and thus hot welding. After the adhesive has been applied, the connecting device can also be hot-glued by heating the connecting device.

Dieser Vorgang des Verbindens der Transportbandenden mittels der Verbindungsvorrichtung erfolgt in dem Zustand, in dem das Transportband 1 - wie in Fig. 5 zu sehen - um die Umlenkrollen 11 und eine Spannrolle 10 eines Bändertischs 9 herumgeführt ist. This process of connecting the conveyor belt ends by means of the connecting device takes place in the state in which the conveyor belt 1 - as can be seen in FIG. 5 - is guided around the deflection rollers 11 and a tensioning roller 10 of a conveyor table 9 .

Somit ist es nicht notwendig, daß zur Montage eines Transportbandes 5 irgendwelche Teile des von einem Stapeltisch 12 zu einer Druckmaschine 13 führenden Bändertischs 9, insbesondere nicht die Lagerungen der Umlenkrollen 11 und Spannrolle 10 abgebaut und anschließend wieder angebaut werden müssen.It is thus not necessary that any parts of the belt table 9 leading from a stacking table 12 to a printing machine 13 , in particular not the bearings of the deflection rollers 11 and tensioning roller 10, have to be dismantled and then reinstalled in order to assemble a conveyor belt 5 .
