"Verfahren und Vorrichtung zur Herstellung von Stangen, Rohren und dergl. aus Glas oder anderen Werkstoffen""Method and device for the production of rods, tubes and the like from glass or other materials"

Glasstangen, welche aus Ausgangstoff für die Herstellung von Knöpfen,Perlen und anderen Gegenständen verwendet werden, stellt man bis jetzt in der Weise her, daß ein Glasposten mittels einer Pfeife wulstartig ausgebildet, mit Hilfe von Zangen zu einem Strang gezogen und zuletzt in einzelne Stücke, sogenannte Stangen, geteilt wird ο Gegenüber diesem Verfahren wird erfindungsgemäß die Glasschmelze oder ein anderer plastischer Werkstoff zu einer Stange oder einem Rohr vorgeformt, in dieser Gestalt während seiner drehenden und zugleich verschiebenden Bewegung auf Schmelztemperatur oder in ihre Nähe gebracht, hierauf mittels Stangen erfaßt, weiter gezogen und schließlich in einzelne Stücke geschnitten. Die zu diesem Zwecke dienende Vorrichtung besteht aus zwei Teilen, wovon eine Gruppe ein Ziehwerk mit Hilfsmitteln für zunehmende Vorschubgeschwingigkeit und gleichzeitige Drehung und einen daran anschließenden Wärmeofen besitzt. Die zweite Gruppe der Vorrichtung enthält zwei übereinander gleichsinnig laufende Förderbahnen und eine an diese anschließende Abtrennvorrichtung, welche den endgültig gezogenen, verarbeitenden Strang in Stangen gewünschte Länge teilt. Man kann Glas, Kunstharz oder andere plastische Massen diesem Arbeitsgange unterwerfen.Glass rods, which are used from raw material for the production of buttons, beads and other objects up to now in such a way that a glass gob is formed into a bead by means of a pipe, with the help of pliers to form a strand is drawn and finally divided into individual pieces, so-called rods or some other plastic material preformed into a rod or tube, in this shape during its rotating and at the same time shifting movement brought to the melting temperature or in its vicinity, then grasped by means of rods, pulled further and finally cut into individual pieces. The device used for this purpose consists of two parts, one of which is a group Pulling mechanism with aids for increasing feed speed and simultaneous rotation and an adjoining heating furnace. The second group of the device contains two conveyor tracks running in the same direction on top of one another and one adjoining them Cutting device, which divides the finally drawn, processing strand into bars of the desired length. Glass, synthetic resin or other plastic masses can be subjected to this process.

Die beiliegende Zeichnung zeigt die Vorrichtung in einem Ausführungsbeispiel als Gesamtanordnung für die Durchführung des Verfahrens. The accompanying drawing shows the device in an exemplary embodiment as an overall arrangement for carrying out the method.

Ein an einen Ofen 1 angeschlossenes Gestell 2 trägt ein Rohr oder eine Düse 3, welche geschmoleanes Glas in Form eines Stranges 4 führt. Der Strang wird in der Richtung des Pfeiles A mit zunehmender Geschwindigkeit weiter gezogen und dabei gleichzeitig um seine Längsachse gedreht. Zu dem Zwecke läuft er durch das Rohr 3, dafr seine Drehung von der Welle 5 über Zahnräder 6 und 7 erhält, wobei das Rad 6 auf der Welle 5 mittels einer Gabel 8, die auf einer Leitspindel 9 hin-und her verschoben werden kann, den Weg des jeweiligen Verschiebens des Stranges mit<*-macht. Die Zunahme des Vorschubes wird erreicht mittels der Kegelräder Io und 11, über welche ein Riemen läuft« Diese Verschiebung des Riemens wird von einer an sich bekannten Vorrichtung in Abhängigkeit vom Antrieb vorgenommen. Die Änderung der Verschiebung kann auch in sonst bekannter Weise von der Antriebs-A frame 2 connected to a furnace 1 carries a tube or a nozzle 3, which melts glass in the form of a strand 4 leads. The strand is pulled further in the direction of arrow A with increasing speed and at the same time around its longitudinal axis turned. For this purpose it runs through the pipe 3, for which it receives its rotation from the shaft 5 via gears 6 and 7, the Wheel 6 on the shaft 5 by means of a fork 8, which can be moved back and forth on a lead screw 9, the path of the respective Moving the line with <* - makes. The increase in feed is achieved by means of the bevel gears Io and 11, over which a belt running «This shifting of the belt is carried out by a device known per se as a function of the drive. The change the displacement can also be influenced by the drive

Claims

side to be carried out. The furnace has a cover 12 at the top. The drawn, twisted and, in the process, warmed up for easier work, reaches the adjoining guiding and dividing device. This has an endless belt 13? which runs over the table 14 with its upper run. A second band 15 is arranged above the belt 13 w © a? IeHo Both belts run in the area of the table in the direction of arrow B and leading stretched lengths detected by means ^of, and mono-

laid strand 4 to a pair of scissors 16, which by hand or by means of an actuator 17, which occasionally simultaneously the Belts are moved, driven and the strand is cut into pieces 18 of the desired length β

The device which stretches and rotates the strand is also actuated by a drive machine 19.

The belt 15 can be pivoted up around its longitudinal edge, so that the strand can be more conveniently inserted into the dividing device. A rotatable drum 2o is attached to the dividing device and carries compartments 21 parallel to the drum axis on the outside of the maj ± el and therefore removes the cut-off ^ G-lasstangen 18 and, while it is rotating around its own axis 22, forwards it to the container located below .

The two devices, ie the stretching device and the dividing device, run on a rail 25 and can therefore be adjusted differently in terms of their distance so that a thicker or thinner (weaker) strand can be obtained on the scissors. The receiving device with the drum 2o can also run along on the track. It is driven by the motor 24. Claims

I. A process for the production of rods, butt pieces of any length from glass or other plastic materials, characterized in that, that the Y / Erkstoff in the plastic state is drawn as a strand, twisted, and at the same time brought to its melting temperature and is then cut into pieces.

3. Apparatus according to claim 2, characterized by a Transpärtbaim and an ATds clone i & e apparatus connected to this.

4. Device according to claims 2 and 3, characterized by a rotating drum, the axis of which is parallel to the direction of movement of the strand runs and through compartments running parallel to the axis of rotation on the outside of the Irommel jacket to accommodate the respective cut rods,

which fall into a container when the drum is turned downwards.

5. Device according to d: en claims 2-4, characterized in that both the stretching device and the sub-machine or one of the two on a track or the like. Are slidably arranged ο

6. Device according to the preceding claims, characterized in that the transport path lies in its ^ above the strand Part has a conveyor belt which is arranged pivotably about its side edge parallel to the direction of movement of the strand.
