Abstract

A gripping device for drawing through extrusions, and particularly for extruded plastics, consists of a caterpillar arrangement with two adjustable-gap track chains, the upper is adjusted pneumatically or hydraulically by pressure from a pump via a lever system, the lower by hand through a lever system. Continuous and adjustable operation. The assembly has track elements and tension in the upper chain is regulated by a lever system operated by a pneumatic hydraulic cylinder. The pressure of this chain is applied by a number of rams working from a hydraulic line. The lower chain is regulated by manually turning a shaft. The whole arrangement is driven by a thyristor-controlled drive for flexibility.

Description

Vorrichtung zum Abziehen von Extrusionsgut, insbesondere für Extruder zum Herstellen von Kunststoffteilen. Device for drawing off extrusions, especially for extruders for the production of plastic parts.

Die Erfindung bezieht sich auf eine Vorrichtung zum Abziehen von Extrusionsgut, insbesondere für Extruder zum Herstellen von Kunststoffteilen.The invention relates to a device for drawing off extrusion material, especially for extruders for the production of plastic parts.

Bei Extrudern oder Wärmeöfen zum Vorbereiten von Schmiedeteilen für den folgenden Arbeitsgang werden vielfach Greifer oder besondere Manipulatoren eingesetzt, besonders dann, wenn es sich um gewichtsmäßig schwere Werkstücke handelt.In extruders or heating furnaces for preparing forgings for In the following work step, grippers or special manipulators are often used, especially when the workpieces are heavy in terms of weight.

Auch bei Druckgießmaschinen ist es üblich, besondere Greifer vorzusehen, die das aus der 1)ruckgießmaschine ausgestoßene Druckgußteil erfassen und einer anderen Arbeitsstätte automatisch zuführen.It is also common for die casting machines to use special grippers, which detect the die cast part ejected from the 1) die casting machine and one to another place of work automatically.

Im Allgemeinen handelt es sich bei diesen bekannten Vorrichtungen um Arbeitsgeräte, die in mehr oder weniger großen Zeitabständen, abhängig von der Schußzahl der Druckgießmaschine oder abhängig von dem Arbeitsvorgang und dem Transportweg des Greifers selbst, zum Einsatz kommen.In general, these are known devices to work equipment that is in more or less large time intervals, depending on the Number of shots of the die casting machine or depending on the work process and the transport route of the gripper itself.

Nach der Erfindung ist die Aufgabe gestellt, eine Vorrichtung zum Abziehen von Extrusionsgut, insbesondere für Extruder zum Herstellen von Kunststoffteilen zu schaffen, mit der es möglich ist, die aus einem Extruder extrudierten Kunststoffteile, wie Kunststoffprofile, Rohre, Schläuche und anderes Extrusionsgut kontinierlich in einer Abzugsvorrichtung abzuziehen.According to the invention the object is to provide a device for Removal of extrusion material, especially for extruders for the production of plastic parts to create, with which it is possible, the plastic parts extruded from an extruder, such as plastic profiles, pipes, hoses and other extruded goods to be withdrawn in a trigger device.

Gelöst wird die gestellte Aufgabe dadurch, daß die Abzugevorrichtung nach der Erfindung aus einem Raupenabzug mit zwei paarweise angeordneten, in eine Richtung laufende, in der Höhe parallel aufeinander einstellbare Raupenstollenketten besteht, wobei die obere Raupe pneumatisch oder hydraulisch mit dem jeweils eingestellten Druck über ein Hebelsystem angepresst und die untere Raupe über ein anderes Hebelsystem von Hand einstellbar und fixierbar ist.The problem posed is achieved in that the trigger device according to the invention from a caterpillar haul-off with two pairs arranged, caterpillar stud chains that run in one direction and are adjustable in height and parallel to each other consists, the upper bead pneumatically or hydraulically with the respectively set Pressure is applied via a lever system and the lower caterpillar via another lever system adjustable and fixable by hand.

In den Zeichnungen ist die Erfindung in einem Ausführungsbeispiele schematisch dargestellt und wird im folgenden näher beschrieben.In the drawings the invention is in one exemplary embodiment shown schematically and is described in more detail below.

Es zeigen: Figur 1 eine Seitenansicht der erfindungsgemäßen Vorrichtung und Figur 2 einen Schnitt nach der Linie A - B in Figur 1.They show: FIG. 1 a side view of the device according to the invention and FIG. 2 shows a section along the line A - B in FIG.

Die erfindungsgemäße Vorrichtung zum Abziehen von Extrusionsgut ist eine kastenförmig stabilisierte Schweißkonstruktion, in der zwei paarweise angeordnete Raupenstollenketten 6 angeordnet sind, um Kunststoffprofile, Rohre, Schläuche und anderes Extrusionsgut in einer Abzugsrichtung abziehen zu können.The device according to the invention for drawing off extrusion material is a box-shaped, stabilized welded construction in which two Crawler cleat chains 6 are arranged to plastic profiles, pipes, hoses and to be able to pull off other extrusion material in a pull-off direction.

Als Hauptelemente wirken zwei Raupenstollenketten 6, die als Kettenumlauf paarweise angeordnet sind.The main elements are two caterpillar cleated chains 6, which circulate as the chain are arranged in pairs.

Die Stollen der Kette sind auf Metallplatten aufgeklebt und austauschbar mit den Winkellaschen der Kette verschraubt.The cleats of the chain are glued to metal plates and are interchangeable screwed to the angle brackets of the chain.

Die Raupenführung der oberen Raupe 1 und der unteren Raupe 2 ist auf Je zwei Irauptwellen gelagert.The caterpillar guide of the upper caterpillar 1 and the lower caterpillar 2 is open Two main shafts each supported.

Die Raupenspannung der oberen Raupe 1 wird zur Erzeugung der erforderlichen Flächenpressung über ein Hebelsystem 3 erreicht, das mit Hilfe von Pneumatik- oder Druckmittelzylinder 5 gleichbleibend gespannt wird.The track tension of the upper track 1 is used to generate the required Surface pressure achieved via a lever system 3, which with the help of pneumatic or Pressure cylinder 5 is constantly tensioned.

Um einen gleichmäßigen Anpreßdruck bei querschnittsverändertem Material zu erreichen, ist die obere Raupenführung 1 mit einer Vielzahl von Kolben 7 ausgestattet.To ensure an even contact pressure with material with a different cross-section To achieve this, the upper caterpillar guide 1 is equipped with a plurality of pistons 7.

Die Kolben 7 sind in einem geschlossenen Hydraulikbett 11 eingelassen, wodurch ein Niveauausgleich gewährleistet ist, was ein elastisches Nachgeben der Raupe 6 unter Beibehaltung des optimalen Anpreßdruckes ermöglicht.The pistons 7 are embedded in a closed hydraulic bed 11, whereby a level compensation is guaranteed, what an elastic yield of the Allows bead 6 while maintaining the optimal contact pressure.

Über die am Kolbenschaft angeschraubte Brücke wird mit Hilfe von zwei Kettenritzel 8 die Druckspannung auf die Raupenstollenkette 6 übertragene Die untere Raupenspannung 2 wird durch das Hebelsystem 4 über eine Gewindespindel 9 von Hand auf Profilhöhe eingestellt und fixiert.The bridge screwed onto the piston skirt is secured with the help of two Chain pinion 8 the compressive stress transferred to the caterpillar stud chain 6 The lower Track tension 2 is through the lever system 4 over a threaded spindle 9 manually adjusted to profile height and fixed.

Der Raupenabzug ist mit einer Abzugskraftanzeige ausgerüstet, wodurch die benötigte Abzugskraft einstellbar und meßbar ist.The caterpillar haul-off is equipped with a pull-off force display, which means the required pull-off force is adjustable and measurable.

Zur Einstellung der Optimalen Abzugsgeschwindigkeit ist eine Digital-Geschwindigkeitsanzeige eingebaut.A digital speed display is used to set the optimum take-off speed built-in.

Der Antrieb 10 der Raupenabzugsvorrichtung wird mit Hilfe von Thyristoren geregelt und bietet somit die Möglichkeit der Außens teuerung.The drive 10 of the caterpillar haul-off device is with the help of thyristors regulated and thus offers the possibility of external control.

Zur Eigenversorgung der Pneumatik oder des Druckmittels 5 im Raupenabzug ist eine Pumpe vorgesehen, die die Maschine zentral speist und den Vorteil zum Anschluß an die gesamte Folgeanlage bietet.For self-supply of the pneumatics or the pressure medium 5 in the caterpillar haul-off a pump is provided that feeds the machine centrally and the advantage of connection to the entire downstream system.
