Abstract

Die Erfindung betrifft eine Einrichtung zum Aufwickeln, Fördern und Abwickeln von Gummiförderbändern, die aus einer Mehrheit von Trommeln besteht, wobei jede von denen auf einachsigen Rahmen mit darauf frei gelagerten Laufrädern montiert ist, indem die Rahmen untereinander gelenkig verbunden sind. Die Trommeln werden selbständig über einen hydraulischen Motor, einem Reduktor sowie eine elastische Kupplung betrieben. Die Trommeln bestehen aus je zwei Seitenwänden, die mit profilierten Balken verbunden sind und in denen frei rotierende, zylindrische Rollen gelagert sind. Die profilierten Balken befinden sich symmetrisch zur Trommelachse und sind so ausgeführt, dass zwischen ihnen ein länglicher Spalt zum Durchführen des Gummi-Förderbandes entsteht, wobei das Gummi-Förderband beim Rotieren der Trommel die oberen zylindrischen Wände der Balken umfasst. Die frei rotierenden Rollen befinden sich parallel zu den seitlichen zylindrischen Wänden der Profilbalken, deren zylindrische Oberfläche ein Radius besitzt, der mit dem Radius der dazugehörenden zylindrischen Rolle identisch ist. Durch das nacheinander synchronisierte Drehen der Trommeln wird ein gleichmäßiges Aufwickeln der gesamten Länge des Gummi-Förderbandes auf die Trommeln der Einrichtung erreicht. Das Abwickeln erfolgt in umgekehrter Reihenfolge.

Die Einrichtung besteht aus sechs Trommeln 1, wobei jede davon zwei Seitenvvände 2 besitzt, die mit Profilbalken 3 verbunden sind, die sich ihrerseits symmetrisch zu der Achse der Trommel 1 befinden. Dio Profilbalken 3 besitzen eine flache Wand 4, eine untere zylindrische Wand 5 und zwei seitliche zylindrische Wände 6, so daß zwischen den unteren flachen Wänden 4 der Profilbalken 3 ein länglicher Spalt zum Durchführen des Gummi-Förderbandes 7 gebildet ist. Das Gummi-Förderband läuft.über die oberen zylindrischen Wände 5 der Profilbalken 3 sowie über die vier freirotierenden zylindrischen Rollen 8. Die Rollen 8 sind in der Seitenwand 2 frei gelagert und befinden sich parallel zu den seitlichen Wänden 6 der Profilbalken 3, indem jede seitliche Wand 6 als eine zylindrische Oberfläche formiert ist, deren Radius mit dem Mittelpunkt der Achse der entsprechepden, dazugehörenden zylindrischen Rolle 8 identisch ist. Die Rahmen 9 der einzelnen Trommeln 1 sind untereinander mit einem sphärischen Gelenk verbunden, wobei die Trommeln 1 individuell durch elastischer Kupplungen 10 und Reduktors 11 von hydraulischen Motoren 12 betrieben werden.The device consists of six drums 1, each of which has two Seitenvvände 2, which are connected to profile bars 3, which in turn are symmetrical to the axis of the drum 1. Dio profile bars 3 have a flat wall 4, a lower cylindrical wall 5 and two lateral cylindrical walls 6, so that between the lower flat walls 4 of the profile bar 3, an elongated gap for carrying out the rubber conveyor belt 7 is formed. The rubber conveyor belt runs over the upper cylindrical walls 5 of the section beams 3 as well as over the four freely rotating cylindrical rollers 8. The rollers 8 are freely supported in the side wall 2 and are parallel to the side walls 6 of the section beams 3, each lateral Wall 6 is formed as a cylindrical surface, whose radius is identical to the center of the axis of the corresponding, corresponding cylindrical roller 8. The frames 9 of the individual drums 1 are interconnected with a spherical joint, wherein the drums 1 are operated individually by elastic couplings 10 and reducer 11 of hydraulic motors 12.

Die Wirkungsweise der erfindungsgemäßen Einrichtung ist wie folgt:The operation of the device according to the invention is as follows:

Das im voraus bis zu der gewünschten Länge, unter Betriebsbedingungen verbundene und auf stationären Trommeln aufgewickelte Gummi-Förderband 7 wird durch die länglichen Spalten aller Trommeln 1 durchgeführt und an der Letzten befestigt. Durch die elastische Kupplung 10, das Reduktor 11 und den hydraulischen Motor 12 wird die letzte Trommel 1 so gedreht, daß auf der selben Trommel I zweischichtig, ³/i2 von der ganzen Länge des Gummi-Förderbande» 7 aufgewickelt wird. Dann wird die letzte Trommel 1 gestoppt und die vorletzte Trommel 1 wird gedreht, wobei auf dieser Trommel zweischichtig, V12 der ganzen Länge des Gummi-Förderbandes 7 aufgewickelt wird; dabei sind V12 von der stationären Trommel 1 und ²In von der letzten Trommel 1 der Einrichtung. Auf diese Weise durch nacheinander synchronisiertes Drehen der Trommeln wird ein gleichmäßiges Aufwickeln der ganzen Länge des Gumn^i-Förderbandes 7 auf der Trommel 1 der Einrichtung erreicht. Das Abwickeln geschieht in umgekehrter Reihenfolge.The rubber conveyor belt 7 connected in advance to the desired length, under operating conditions and wound on stationary drums, is passed through the elongated columns of all the drums 1 and fastened to the latter. By the elastic coupling 10, the reducer 11 and the hydraulic motor 12, the last drum 1 is rotated so that on the same drum I two layers, ³ / i2 of the entire length of the rubber conveyor belt »7 is wound. Then, the last drum 1 is stopped and the penultimate drum 1 is rotated, being wound on this drum in two layers, V12 the whole length of the rubber conveyor belt 7; where V12 from the stationary drum 1 and ² In from the last drum 1 of the device. In this way, by successively synchronized rotation of the drums uniform winding of the entire length of the Gumn ^ i conveyor belt 7 is achieved on the drum 1 of the device. The unwinding happens in reverse order.
