Description

Die Erfindung bezieht sich auf eine \rorrichtung zum Entfernen der noch plastischen, durch Aufwickeln von Asbest-Zement-Platten gebildeten Röhren vom Wickeldorn. Es sind Vorrichtungen bekannt, mit Hilfe deren das noch weiche Rohr durch an seiner Außenseite angreifende Greif- oder Halteorgane gehalten und der Wickeldorn aus dem noch weichen Rohr herausgezogen wird. Um diese Arbeit zu erleichtern und um zu verhindern, daß auch bei raschem Arbeiten das Rohr durch den zum festen Klemmen und Halten nötigen Druck seine runde Form verliert, kann die den Gegenstand der Erfindung bildende, in der Zeichnung beispielsweise dargestellte Vorrichtung mit Vorteil benutzt werden.The invention relates to a \ r orrichtung the still plastic, tubes formed by winding of asbestos-cement plates from the mandrel to remove it. Devices are known with the aid of which the pipe, which is still soft, is held by gripping or holding organs acting on its outside, and the winding mandrel is pulled out of the pipe, which is still soft. In order to facilitate this work and to prevent the pipe from losing its round shape due to the pressure required for firm clamping and holding, even when working quickly, the device forming the subject of the invention, for example shown in the drawing, can be used with advantage.

Bei der schematisch dargestellten Vorrichtung ist an einem Gestell 1 eine Welle 2, an welcher das eine Ende einer Gewebebahn 3 befestigt ist, drehbar gelagert. Die letztere ist über Walzen 4, 5 und 6 geführt, von denen die Walze 4 in den Enden von Armen 7, die auf einer Welle 17 des Gestelles 1 schwenkbar angeordnet sind, drehbar gelagert ist. An den Armen 7 greift die Kolbenstange 8 eines Druckluftzylinders 9 an, der mittels Zapfen π drehbar am Gestell 1 angeordnet ist. Am Zylinder 9 sind Druckluf tzu- und -ableitungen angeschlossen, die mit einer von Hand zu bedienenden Steuervorrichtung 12 in Verbindung stehen. Die Gewebebahn 3 ist an der Walze 6 befestigt. Letztere sitzt in Lagern 13, die am Gestell 1 mittels Schraubenspindel 14 verschiebbar angeordnet sind.In the device shown schematically, a shaft 2 is attached to a frame 1 which is attached to one end of a fabric web 3, rotatably mounted. The latter is guided over rollers 4, 5 and 6, of which the roller 4 in the ends of arms 7, the are pivotably arranged on a shaft 17 of the frame 1, is rotatably mounted. To the Arms 7 engages the piston rod 8 of a compressed air cylinder 9, which by means of a pin π is rotatably arranged on the frame 1. On the cylinder 9 are compressed air tzu- and discharge lines connected to a manually operated control device 12 in connection stand. The fabric web 3 is attached to the roller 6. The latter is in camps 13, which on the frame 1 by means of screw spindle 14 are arranged displaceably.

Das Rohr R mit dem Aufwickeldorn S wird, wie in der Zeichnung dargestellt, in eine Schlaufe 15 der Gewebebahn 3 eingelegt, welche an dieser Stelle in an sich bekannter Weise mit Streifen 16 aus Holz o. dgl. belegt ist, die ihrerseits mit feinen Spitzen, mit Leder o. dgl. gegen den Umfang dies nochplastischen Asbest-Zement-Rohres R angepreßt werden. Das Anpressen der Streifen 16 erfolgt durch Verstellen der Walze 4 mittels der Kolbenstange unter Verwendung von Druckluft, der Druck kann beliebig groß gewählt werden. Dabei wird das Rohri? nahezu am ganzen Umfang mit überall gleich hohem Druck von den Klemmitteln 16 gefaßt. Diese halten das Rohr R so fest, daß der Dorn 6" ausgezogen werden kann, ohne daß, auch bei raschem Arbeiten, das Rohr deformiert würde. Durch Verstellen der Lager 13 kann die Schlaufe 15 größer oder kleiner gemacht und dadurch dem Durchmesser des jeweils vom Dorn 5 abzuziehenden Rohres R angepaßt werden. Der Walze 4 wird in ihren Lagern in den Armen 7 etwas Spiel gegeben, so daß das Rohr R auf seiner ganzen Länge gleichmäßig gefaßt werden kann.The tube R with the winding mandrel S is, as shown in the drawing, inserted into a loop 15 of the fabric web 3, which is covered at this point in a manner known per se with strips 16 of wood or the like, which in turn have fine points , o with leather. the like. this still plastic asbestos-cement pipe R are pressed against the periphery. The strips 16 are pressed on by adjusting the roller 4 by means of the piston rod using compressed air; the pressure can be selected as large as desired. The Rohri? The clamping means 16 gripped almost the entire circumference with the same high pressure everywhere. These hold the tube R so tight that the mandrel 6 "can be pulled out without the tube being deformed, even when working quickly. By adjusting the bearings 13, the loop 15 can be made larger or smaller and thereby the diameter of the respective Mandrel 5 can be adapted to the pipe R to be withdrawn. The roller 4 is given some play in its bearings in the arms 7, so that the pipe R can be gripped evenly over its entire length.

Statt mit Druckluft könnte die Walze 4 auch mittels Druckwassers verstellt werden, wobei gleichfalls Mittel vorhanden sind, um den Druck zu regeln.Instead of using compressed air, the roller 4 could also be adjusted using pressurized water, there are also means to regulate the pressure.
