Abstract

The belt table is taken over a drivable belt roller at one end of the table and back round it and over its table board. The table board is split, bordering the transporting belt (7) on both sides. A table board element (6) is able to turn about a turning axis in the region of the belt roller, taking it out of the plane of the table board. The belt roll can be separated by a coupling in the separating region between the table plate and the table plate element.

Description

Die Neuerung bezieht sich einen Bändertisch mit einer Tischplatte über die Bogen von einem Bogenanleger zu einer Bogen verarbeitenden Maschine, insbesondere zu einer Druckmaschine transportierbar sind, mit einem oder mehreren Transportbändern, insbesondere mit im Bereich von durchgehenden Saugöffnungen an ihrer Unterseite mit Saugluft beaufschlagbaren Saugbändem, die über eine drehbar antreibbare Bänderwalze an einem Ende des Bändertischs und eine insbesondere frei drehbar gelagerte Umlenkwalze am anderen Ende des Bändertischs endlos um den Bändertisch und über die Tischplatte geführt und mittels Spannvorrichtungen spannbar sind.The innovation relates to a belt table with a table top over the sheet from a sheet feeder to a sheet-processing machine, in particular to a printing machine are transportable, with one or more conveyor belts, in particular in the range of continuous suction openings on its underside acted upon by suction Saugbändem, the via a rotatably drivable band roller at one end of the belt table and a particular freely rotatably mounted guide roller at the other end of the belt table endlessly guided around the belt table and on the table top and tensioned by means of clamping devices.

Sollen bei derartigen Bändertischen neue Transportbänder eingebaut werden, so werden diese als offenes Transportband um den Bändertisch herumgeführt und dann die beiden Enden durch Verkleben miteinander verbunden.If new conveyor belts are to be installed in such belt tables, they are guided around the belt table as an open conveyor belt and then the two ends are connected to one another by gluing.

Dieser Vorgang erfordert eine erhebliche Zeit, in der der Bändertisch nicht für den Betrieb zur Verfügung steht.This process requires a considerable amount of time in which the belt table is not available for operation.

Aufgabe der Neuerung ist es daher einen Bändertisch der eingangs genannten Art zu schaffen, der auf einfache Weise einen schnellen Aus- und Einbau eines Transportbandes ermöglicht.The object of the innovation is therefore to provide a belt table of the type mentioned, which allows a simple way a quick removal and installation of a conveyor belt.

Diese Aufgabe wird neuerungsgemäß dadurch gelöst, dass die Tischplatte parallel und angrenzend an das Transportband in ein Tischplattenteil und ein Tischplattenelement geteilt ist und das Tischplattenelement um eine Schwenkachse im Bereich der Bänderwalze aus der Ebene der Tischplatte herausklappbar ist, sowie die Bänderwalze im Trennbereich zwischen dem Tischplattenteil und dem Tischplattenelement eine trennbare Kupplung aufweist.
Diese Ausbildung ermöglicht es durch einfaches Herausklappen des Tischplattenelements aus der Ebene der Tischplatte die Bänderwalze und die Umlenkwalze unmittelbar neben dem Bereich des Transportbandes frei zugänglich zu machen, sodass ungehindert ein seitliches Abziehen und ein seitliches Aufbringen des vorher bereits zum Endlosband vorbereiteten Transportbandes erfolgen kann. Damit ist nach nur kurzer Unterbrechung der Bändertisch wieder betriebsbereit, sodass die Rüstzeit gering ist.This object is achieved according to the innovation in that the table top is divided parallel and adjacent to the conveyor belt in a tabletop part and a tabletop element and the tabletop element about a pivot axis in the band roll out of the plane of the table top is folded out, and the band roller in the separation area between the tabletop part and the tabletop element has a separable coupling.
This design makes it possible by simply folding out the table top element from the plane of the table top, the band roller and the guide roller to make freely accessible immediately next to the area of the conveyor belt, so that a lateral removal and lateral application of the previously prepared to the endless belt conveyor belt can be done without hindrance. Thus, after only a brief interruption of the belt table is ready for use again, so that the set-up time is low.

Besondere Werkzeuge für den Ein- und Ausbau des Transportbandes sind nicht erforderlich.Special tools for the installation and removal of the conveyor belt are not required.

Sind mehrere Transportbänder vorhanden, so kann mit nur einem Tischplattenelement eine leichte Zugänglichkeit zu zwei Transportbändern erreicht werden, wenn das Tischplattenelement zwischen zwei Tischplattenteilen angeordnet ist, um die jeweils ein Transportband angrenzend an einen Trennbereich geführt ist, wobei die Bänderwalze in beiden Trennbereichen zwischen einem Tischplattenteil und dem Tischplattenelement eine trennbare Kupplung aufweist.If several conveyor belts are present, easy accessibility to two conveyor belts can be achieved with only one table top element if the table top element is arranged between two table top parts, around which a conveyor belt is guided adjacent to a separating area, wherein the belt roller in both separating areas between a table top part and the tabletop element has a separable coupling.

Eine freie Zugänglichkeit im Bereich der Umlenkwalze wird dadurch erreicht, dass jedem Transportband eine eigene unabhängige Umlenkwalze zugeordnet ist.Free accessibility in the region of the deflection roller is achieved by assigning each conveyor belt its own independent deflection roller.

Die Schwenkachse des Tischplattenelements kann in Längserstreckungsrichtung der Transportbänder auf der der Tischplatte abgewandten Seite der Bänderwalze angeordnet sein.The pivot axis of the tabletop element may be arranged in the longitudinal direction of the conveyor belts on the side facing away from the table top of the belt roller.

Eine besonders kompakte Ausbildung wird aber erreicht, wenn die Schwenkachse des Tischplattenelements sich koaxial zur Drehachse der Bänderwalze erstreckt.A particularly compact design is achieved, however, if the pivot axis of the tabletop element extends coaxially to the axis of rotation of the band roller.

Eine Trennbarkeit und Verbindbarkeit der Bänderwalze wird auf einfache Weise dadurch erreicht, dass im Bereich des Tischplattenelements eine Kupplungshülse um die Drehachse der Bänderwalze frei drehbar gelagert ist, die eine zur Drehachse koaxiale und zum Trennbereich hin offene Kupplungsausnehmung besitzt, in die ein drehfest mit dem von dem Transportband umschlungenen Bereich der Bänderwalze verbundenes, axial in diesem Bereich bewegbares Kupplungselement formschlüssig axial einführbar ist.A separability and connectivity of the band roll is achieved in a simple manner by having a coupling sleeve freely rotatably mounted about the axis of rotation of the band roll in the region of the table top element, which has a coupling axis which is coaxial to the axis of rotation and open towards the separating region, into which a rotationally fixed manner the conveyor belt looped region of the band roll connected, axially movable in this area coupling element is positively inserted axially.

Dabei ist mit einfachen Mitteln das Kupplungselement dadurch bewegbar, dass das Kupplungselement eine koaxiale Gewindebohrung besitzt, in die eine drehbar antreibbare Gewindestange eingreift.In this case, the coupling element is movable by simple means, characterized in that the coupling element has a coaxial threaded bore, into which engages a rotatably driven threaded rod.

Zur Drehbewegungsübertragung kann das Kupplungselement über eine zur Drehachse der Bänderwalze axiale Nut-/Feder-Verbindung formschlüssig mit der Bänderwalze und der Kupplungshülse verbindbar sein.
Auch können die Kupplungselemente einseitig mit einer Nut-/Feder-Verbindung und andererseits mit einer Klemmverbindung versehen werden, sodass sich eine vereinfachte Einkupplung ergibt.
Ebenso können die Kupplungselemente mit einer Kupplungshülse und einem Wellenelement jeweils mit entsprechender Keilverzahnung zur Übertragung größerer Kräfte versehen sein.For rotational movement transmission, the coupling element can be connected in a form-fitting manner with the band roller and the coupling sleeve via a groove / spring connection axial to the axis of rotation of the band roller.
Also, the coupling elements can be provided on one side with a tongue and groove connection and on the other hand with a clamping connection, so that there is a simplified engagement.
Likewise, the coupling elements may be provided with a coupling sleeve and a shaft member each having corresponding splines for transmitting larger forces.

Um die endgültige Kuppelposition zu definieren, ist vorzugsweise das Kupplungselement bis zur Anlage an einem Anschlag in die Kupplungsausnehmung der Kupplungshülse einführbar.In order to define the final dome position, the coupling element is preferably inserted until it abuts against a stop in the coupling recess of the coupling sleeve.

Eine genaue Zuordnung zueinander von Tischplattenteil und Tischplattenelement in der Arbeitsstellung wird dadurch erreicht, dass das Tischplattenteil an seiner dem Trennbereich zugewandten Seite Positionierelemente besitzt, die in entsprechende Positionierausnehmungen an der Unterseite des Tischplattenelements eingreifbar sind.An exact assignment to each other of the tabletop part and table top element in the working position is achieved in that the tabletop part has at its side facing the separation area positioning elements, which are engageable in corresponding positioning recesses on the underside of the tabletop element.

Dabei können in einfacher Ausbildung die Positionierelemente durch eine sich parallel zu dem Transportband erstreckende Positionierstange gebildet sein und die Positionierausnehmungen zur Unterseite des Tischplattenelements hin offene Positioniernuten sein, die in der Arbeitsposition des Tischplattenelements mit ihrem Nutengrund auf der Positionierstange in Auflage sind.In this case, in a simple embodiment, the positioning elements may be formed by a positioning rod extending parallel to the conveyor belt and the positioning recesses being open towards the underside of the tabletop element, which in the working position of the tabletop element are in contact with the groove base on the positioning rod.

Eine Stabilität der gesamten Tischplatte in ihrer Arbeitsstellung wird dadurch erreicht, dass das Tischplattenelement in seiner Arbeitsposition an dem Tischplattenteil arretierbar ist.A stability of the entire table top in its working position is achieved in that the table top element can be locked in its working position on the table top part.

Dies wird in einfacher Weise dadurch erreicht, dass das Tischplattenelement mittels einer oder mehrerer Rastvorrichtung an dem Tischplattenteil arretierbar ist, wobei an der dem Tischplattenteil zugewandten Seite des Tischplattenelements Rastbolzen angeordnet sein können, die in ihnen gegenüberliegend an dem Tischplattenteil ausgebildete Rastöffnungen eingreifbar sind und entgegen einer Federkraft von dem Tischplattenteil weg aus den Rastöffnungen heraus bewegbar sind.This is achieved in a simple manner in that the tabletop element can be locked by means of one or more locking device on the tabletop part, wherein on the tabletop part facing side of the tabletop element latching bolts can be arranged in the opposite them formed on the tabletop part latching openings are engageable and against one Spring force of the tabletop part away from the locking openings are movable out.

Der in den Figuren dargestellte Bändertisch besitzt eine Tischplatte 1, vor deren in Förderrichtung 2 vorderem Ende eine Bänderwalze 3 und hinter deren hinterem Ende koaxial zueinander mehrere Umlenkwalzen 4 angeordnet sind. Die Bänderwalze 3 ist durch einen nicht dargestellten Antrieb um eine Drehachse 9 drehbar antreibbar.The belt table shown in the figures has a table top 1, in front of which in the conveying direction 2 front end of a belt roller 3 and behind the rear end coaxial with each other a plurality of guide rollers 4 are arranged. The belt roller 3 is rotatably driven by a drive, not shown, about an axis of rotation 9.

Die Tischplatte 1 besteht aus zwei im Abstand nebeneinander angeordneten Tischplattenteilen 5 und einem in den Trennbereich 23 zwischen den Tischplattenteilen 5 angeordneten Tischplattenelement 6.The table top 1 consists of two spaced apart side panel parts 5 and arranged in the separation area 23 between the table top parts 5 tabletop element. 6

Jeweils angrenzend an das Tischplattenelement 6 sind endlose Transportbänder 7 über die Tischplattenteile 5 und die Bänderwalze 3 sowie die Umlenkwalzen 4 um den Bändertisch geführt, wobei die Transportbänder 7 auf der Unterseite des Bändertischs noch durch Spannrollen 8 einer Spannvorrichtung spannbar sind.In each case adjacent to the table top element 6 endless conveyor belts 7 are guided over the table top parts 5 and the belt roller 3 and the guide rollers 4 to the belt table, the conveyor belts 7 on the underside of the belt table are still tensioned by tension rollers 8 a tensioning device.

Das Tischplattenelement 6 ist um eine zur Drehachse 9 koaxiale Schwenkachse aus der in Arbeitsposition gemeinsamen Ebene mit den Tischplattenteilen 5 an Lagerböcken 10 nach oben herausschwenkbar auf einer Kupplungshülse 11 gelagert, die axial feststehend aber um die Drehachse 9 frei drehbar gelagert ist.The tabletop element 6 is mounted about a pivot axis coaxial with the axis of rotation 9 from the common in working position with the table top parts 5 on bearing blocks 10 upwardly pivotable on a coupling sleeve 11 which is axially fixed but freely rotatable about the axis of rotation 9.

Die Kupplungshülse 11 besitzt eine als durchgehende Bohrung ausgebildete Kupplungsausnehmung 12 mit einer axialen Nut 13.The coupling sleeve 11 has a trained as a through bore coupling recess 12 with an axial groove thirteenth

Koaxial dazu ist in der Bänderwalze 3 eine entsprechende Ausnehmung 14 mit Nut 15 vorgesehen.Coaxially thereto, a corresponding recess 14 with groove 15 is provided in the band roll 3.

Ein dem Querschnitt der Kupplungsausnehmung 12 und der Ausnehmung 14 entsprechendes Kupplungselement 16 ist in der Kupplungsausnehmung 12 und der Ausnehmung 14 axial verschiebbar angeordnet und greift mit einer Feder 14 in die Nuten 13 und 15 ein, sodass die Bänderwalzen 3 über die Kupplungselemente 16 und die Kupplungshülse 11 drehfest miteinander verbunden sind.A cross-section of the coupling recess 12 and the recess 14 corresponding coupling element 16 is axially slidably disposed in the coupling recess 12 and the recess 14 and engages with a spring 14 in the grooves 13 and 15, so that the band rollers 3 via the coupling elements 16 and the coupling sleeve 11 rotatably connected to each other.

Die Kupplungselemente 16 besitzen koaxiale Gewindebohrungen 18, in die jeweils von einem seitlichen Maschinengestellteil 19 her durch koaxiale Ausnehmungen 21 in den Bänderwalzen 3 hindurchgeführte Gewindestangen 20 eingreifen.The coupling elements 16 have coaxial threaded bores 18, in each of which engage from a lateral machine frame part 19 by coaxial recesses 21 in the band rollers 3 threaded rods 20 engage.

Durch Verdrehen der Gewindestangen 20 an ihrem dem Maschinengestellteil 19 zugewandten Ende ist das jeweilige Kupplungselement 16 derart axial verschiebbar, dass es aus der Kupplungshülse 11 heraus und in die Bänderwalze 3 hineinbewegt wird.By turning the threaded rods 20 at its end facing the machine frame part 19, the respective coupling element 16 is axially displaceable such that it is moved out of the coupling sleeve 11 and into the band roller 3.

Damit wird im Trennbereich 23 ein Spielraum zwischen der Bänderwalze 3 und der Kupplungshülse 11 geöffnet, über den bei hochgeklapptem Tischplattenelement 6 das bereits endlos vorbereitete Transportband 7 seitlich auf die Bänderwalze 3 aufgeschoben werden kann.Thus, a clearance between the band roller 3 and the coupling sleeve 11 is opened in the separation region 23, on the already endlessly prepared conveyor belt 7 can be pushed laterally on the band roller 3 with folded table top element 6.

Am anderen Ende des Bändertischs erfolgt auf gleiche Weise ein seitliches Aufschieben des Transportbandes 7 auf eine durch das Hochklappen des Tischplattenelements 6 seitlich freie Umlenkwalze 4.At the other end of the belt table takes place in the same way a lateral pushing the conveyor belt 7 on a laterally free by the folding of the table top element 6 deflection roller. 4

Durch Verdrehen der Gewindestange 20 in entgegengesetzte Richtung kann nun das Kupplungselement 16 wieder in die Kupplungsausnehmung 12 eingeführt werden, bis es axial an einem Anschlag 22 zur Anlage gelangt.By rotating the threaded rod 20 in the opposite direction, the coupling element 16 can now be reintroduced into the coupling recess 12 until it comes to rest axially against a stop 22.

Damit ist wieder eine drehfeste Verbindung der Bänderwalzen 3 hergestellt.This is again a rotationally fixed connection of the band rollers 3 made.

Als Alternative zur drehfesten Verbindung der Wellenteile der Bänderwalze 3 der oben beschriebenen Art kann vorgesehen sein, dass die Nut-/Feder-Verbindung im Bereich der mittigen Lagerung der Bänderwalze 3 im Bereich der Kupplungsausnehmung 12 durch eine Klemmverbindung ersetzt wird. Hierbei ist das Kupplungselement 6 auf der Außenseite der Bänderwalze 3 weiterhin mit einer Nut-/Feder-Verbindung versehen, wobei die Passfeder aber nicht mehr bis in den Bereich der Kupplungsausnehmung 12 reicht. Nach dem Einschieben des Kupplungselementes 6 in die Kupplungsausnehmung 12 wird das Kupplungselement 6 dort einfach festgeklemmt. Dadurch wird das Einführen des Kupplungselementes drehlagenunabhängig und damit vereinfacht.As an alternative to the rotationally fixed connection of the shaft parts of the band roller 3 of the type described above, it can be provided that the tongue and groove connection in the region of the central support of the band roller 3 in the region of the coupling recess 12 is replaced by a clamping connection. Here, the coupling element 6 is further provided on the outside of the band roll 3 with a tongue and groove connection, the key but no longer extends into the region of the coupling recess 12. After insertion of the coupling element 6 in the coupling recess 12, the coupling element 6 is simply clamped there. As a result, the insertion of the coupling element is rotational position independent and thus simplified.

Als weitere Alternative sind das Kupplungselement 6 und die Kupplungsausnehmung 12 mit einander entsprechenden Keilverzahnungen versehen. Dadurch ergibt sich für die Verbindung eine höhere Belastbarkeit, insbesondere für den Einsatz bei großformatigen Bändertischen.As a further alternative, the coupling element 6 and the coupling recess 12 are provided with mutually corresponding splines. This results in a higher load capacity for the connection, in particular for use in large-sized belt tables.

Nun wird das Tischplattenelement 6 wieder in seine Betriebsposition heruntergeklappt, in der es an der Oberseite eine Ebene mit den Oberseiten der Tischplattenteile 5 bildet.Now the table top element 6 is folded down again into its operating position, in which it forms a plane with the upper sides of the tabletop parts 5 at the top.

Das Tischplattenelement 6 besitzt an seiner Unterseite mehrere in Längserstreckungsrichtung des Tischplattenelements 6 im Abstand zueinander angeordnete Querstege 24, in denen Positioniemuten 25 ausgebildet sind. Diese Positioniemuten 25 erstrecken sich in Förderrichtung 2 und sind zur dem Tischplattenelement 6 abgewandten Seite hin offen.The tabletop element 6 has on its underside a plurality of spaced apart in the longitudinal direction of the table top element 6 transverse webs 24, in which position grooves 25 are formed. These Positioniemuten 25 extend in the conveying direction 2 and are open to the tabletop element 6 side facing away.

In der Betriebsposition des Tischplattenelements 6 greifen Positionierstangen 26 in die Positioniernuten 25 ein und sind an dem Nutengrund der Positioniernuten 25 in Anlage.In the operating position of the table top element 6, positioning rods 26 engage in the positioning grooves 25 and abut against the groove base of the positioning grooves 25.

Die Positionierstangen 26 erstrecken sich in Förderrichtung 2 und sind an der dem Trennbereich 23 zugewandten Seite der Tischplattenteile 5 mittels Halteelementen 27 in einem Abstand dazu befestigt.The positioning rods 26 extend in the conveying direction 2 and are secured to the separating region 23 facing side of the tabletop parts 5 by means of holding elements 27 at a distance therefrom.

Die Halteelemente 27 befinden sich quer zur Förderrichtung 2 in Reihe den Querstegen 24 gegenüberliegend und weisen zu den Querstegen 24 hin offene Rastöffnungen 28 auf.The holding elements 27 are located transversely to the conveying direction 2 in series, the transverse webs 24 opposite and have to the transverse webs 24 open towards locking openings 28.

Den Rastöffnungen 28 in der Betriebsposition des Tischplattenelements 6 gegenüberliegend sind in den Führungsausnehmungen der Querstege 24 entsprechende Rastbolzen 29 quer zur Förderrichtung 2 verschiebbar geführt und in Ausfahrrichtung aus dem Quersteg 24 federbelastet.The latching openings 28 in the operating position of the table top element 6 are opposite in the guide recesses of the transverse webs 24 corresponding latching pins 29 transversely to the conveying direction 2 slidably guided and spring-loaded in the extension direction of the transverse web 24.

An ihren aus den Führungsausnehmungen herausragenden Enden besitzen die Rastbolzen 29 rampenartige Fasen. Dadurch werden die Rastbolzen 29 beim Einklappen des Tischplattenelements 6 von den Haltelementen 27 entgegen ihrer Federbelastung in die Führungsausnehmungen hineingedrückt und rasten bei Erreichen der Betriebsposition des Tischplattenelements 6 das Tischplattenelement 6 arretierend in die Rastöffnungen 28 ein.At their protruding from the guide recesses ends, the locking pins 29 have ramp-like chamfers. As a result, when the table top element 6 is folded in, the latching pins 29 are pressed by the holding elements 27 against their spring load into the guide recesses and latch into the latching openings 28 when the tabletop element 6 reaches the operating position of the tabletop element 6.

Zum Hochklappen des Tischplattenelements 6 muss diese Rastkraft nur überwunden werden, um die Rastbolzen 29 aus den Rastöffnungen 28 herauszubewegen.To fold up the table top element 6, this latching force must only be overcome in order to move the latching pin 29 out of the latching openings 28.
