Description
Ausziehbares, in jeder Stellung betriebsfertiges Förderband. Bei Förderbandfördereinrichtungen ist es bekannt, das Förderband über ein verschiebbares Leitrollensystem derart zu führen, daß die nutzbare Förderlänge nach Bedarf eingestellt werden kann. Für viele Zwecke ist es nun erforderlich, daß das Förderband auf der Förderstrecke derart abgestützt wird, daß es auf . dieser ganzen Länge in der Förderebene gehalten bleibt. Gemäß der vorliegenden Erfindung ist hier nun eine Einrichtung geschaffen, durch «-elche dies ermöglicht wird und dabei trotzdem eine beliebige Einstellbarkeit der Förderlänge angewendet werden kann, und zwar geschieht das dadurch, daß das Förderband teilweise durch umlegbare Stützrollen getragen wird, welche sich beim Verkürzen der Förderstrecke umlegen und beim Verlängern derselben von selbst wieder aufrichten.Extendable conveyor belt that is ready for use in any position. With conveyor belt systems it is known to control the conveyor belt in this way via a sliding guide roller system lead that the usable conveying length can be adjusted as required. For many Purposes, it is now necessary that the conveyor belt on the conveyor line in such a way that it is based on. this entire length is kept in the conveying plane. In accordance with the present invention, a device is now provided by «-Which this is made possible and at the same time any adjustability of the Conveyor length can be used, and that happens in that the conveyor belt is partly carried by foldable support rollers, which are shortened when shortening of the conveyor line and straighten it up automatically when it is extended.
Die Erfindung ist auf der beiliegenden Zeichnung schematisch in einer Seitenansicht dargestellt.The invention is shown schematically on the accompanying drawing in a Side view shown.
Man erkennt aus der Zeichnung das zweiteilige Fahrgestell a, b, welches im Darstellungsbeispiel auf Laufrollen c fahrbar gemacht ist und welches mittels der Tragrollen d und e sowie der Führungs- und Spannrollen f, g, lt, i das Förderband k trägt. Die obere nutzbare Strecke des Förderbandes wird durch Stützrollen L abgetragen. In der Zeichnung ist nun ausgezogen die Stellung bei größter Förderlänge des Bandes dargestellt, und in strichpunktierten Linien ist die Stellung bei kleinster Förderlänge veranschaulicht. Wie aus der Zeichnung erkenntlich, wird bei der Bewegung des Gestellteiles b durch die Führungsrolle i das Förderband h immer so gespannt, daß es in jeder Stellung betriebsbereit bleibt. Da nun der entsprechende Teil der Stützrollen l bei einer Verkürzung der Förderlänge in Fortfall kommt, ist dieser Teil der Stützrollen l durch Gewichtshebel m umlegbar gemacht, und sobald diese umlegbaren Stützrollen gegen die vordere schräge Fläche der Leitschienen ia stoßen, werden sie aus ihrer Arretiervorrichtung, die sie in der senkrechten Lage festgehalten hat, ausgelöst und umgelegt. Sobald das Förderband wieder verlängert wird, richten sich diese Stützrollen von selbst wieder auf und stellen sich fest.The drawing shows the two-part chassis a, b, which is made mobile on rollers c in the example shown and which carries the conveyor belt k by means of the support rollers d and e and the guide and tensioning rollers f, g, lt, i. The upper usable section of the conveyor belt is removed by support rollers L. In the drawing, the position with the greatest conveying length of the belt is now shown in solid lines, and the position with the smallest conveying length is illustrated in dash-dotted lines. As can be seen from the drawing, when the frame part b is moved by the guide roller i, the conveyor belt h is always tensioned so that it remains ready for operation in every position. Since the corresponding part of the support rollers l no longer applies when the conveying length is shortened, this part of the support rollers l is made foldable by weight levers m, and as soon as these foldable support rollers hit the front inclined surface of the guide rails in general, they are released from their locking device, which she has held in the vertical position, triggered and knocked down. As soon as the conveyor belt is extended again, these support rollers straighten themselves up again and fix themselves.
Die Bewegung der beiden Gestellteile a und b gegeneinander kann auf beliebige Weise, z. B. durch eine Kettenwinde o o. dgl., erfolgen.The movement of the two frame parts a and b against each other can on any way, e.g. B. by a chain winch o o. The like., Take place.
