Abstract

In the case of a tool for grasping a hollow article blow moulded in a blow moulding machine, for further conveying it to a succeeding station, the aim is to carry out the retooling to a different mould rapidly and with simple means. For this purpose, a removal mandrel is proposed, which can be introduced into the neck orifice of the hollow article, can be subjected to compressed air and has a sleeve element which is covered with a jacket of elastomeric material. On compressed-air supply, the compressed air passes below the jacket and expands it elastically until the jacket comes to bear against the inner wall of the neck orifice, and a firm connection is thus formed between the hollow article and grasping mandrel. The removal mandrel is exchangeably attached, by means of a quick-closure coupling of a known kind, to a carrier head, by means of which the removal mandrel with the hollow article can be transported to a succeeding station.

Description

Die Erfindung betrifft ein Werkzeug zur Erfassung eines in einer Blasformmaschine geblasenen flaschenartigen Hohlkörper in dessen Halsbereich.The invention relates to a tool for detecting a a blow-molding machine blown bottle-like hollow body in its neck area.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Werkzeug der genannten Art die Umrüstung der Blasformmaschine bei der Umstellung von einem Blasprodukt auf ein anderes schnell und mit einfachen Mitteln durchführen zu können.The invention has for its object in a tool of the type mentioned the conversion of the blow molding machine at the Switching from one blow product to another quickly and to be able to carry out with simple means.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved by the characterizing Features of claim 1 solved.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert.An embodiment of the invention is described below the drawing explained in more detail.

Diese zeigt einen Erfassungsdorn 1, der, wie in unterbrochenen Linien dargestellt, in einer han­ delsüblichen Schnellschließkupplung 2 gehalten ist. Die Schnellschließkupplung 2 ist fest mit einem Trägerkopf 3 ver­ bunden. This shows a detection mandrel 1 , which, as shown in broken lines, is held in a standard quick release coupling 2 . The quick release coupling 2 is fixed to a carrier head 3 a related party.

Der Erfassungsdorn 1 besteht aus einem zentralen Rohrteil 4, an dessen unteren Ende die Dornspitze 5 befestigt ist. Über das Rohrteil 4 ist ein Hülsenelement 6 geschoben, das zwischen der Dornspitze 5 und einem Anschlagelement 7 eingeklemmt ist.The detection mandrel 1 consists of a central tube part 4 , at the lower end of which the mandrel tip 5 is fastened. A sleeve element 6 is pushed over the tubular part 4 and is clamped between the mandrel tip 5 and a stop element 7 .

Das Hülsenelement 6 besteht aus einer metallischen Hülse 8, die von einem Mantel 9 aus elastomerem Material umhüllt ist. Der Mantel 9 ist am oberen und am unteren Rand der Hülse 8 fest und gasdicht mit dieser verbunden und liegt im übrigen Bereich ver­ bindungsfrei auf der Außenfläche der Hülse 8 auf. Über eine ra­ diale Öffnung 10 in der Hülse 8 und über eine radiale Bohrung 11 in Rohrteil 4 ist zwischen der Außenfläche der Hülse 8 und dem Mantel 9 Druckluft einleitbar, wodurch sich der Mantel 9 unter einer Durchmessererweiterung elastisch aufweitet und in der Halsöffnung eines flaschenartigen Hohlkörpers 12 verspreizt.The sleeve element 6 consists of a metallic sleeve 8 , which is encased by a jacket 9 made of elastomeric material. The jacket 9 is firmly and gas-tightly connected to the upper and lower edges of the sleeve 8 and lies in the rest of the region without any binding on the outer surface of the sleeve 8 . Via a ra diale opening 10 in the sleeve 8 and a radial bore 11 in the tubular part 4 , compressed air can be introduced between the outer surface of the sleeve 8 and the jacket 9 , whereby the jacket 9 expands elastically with a diameter expansion and in the neck opening of a bottle-like hollow body 12 spread.

Im Betrieb wird der Erfassungsdorn 1 an einer Ausgangsstation, beispielsweise an einer Stanzmaske einer Blasformmaschine, mit dem Anschlußkopf 3 senkrecht in die Halsöffnung des Hohlkörpers 12 abgesenkt, bis das Anschlagelement 7 am oberen Rand der Halsöffnung zur Auflage kommt. Anschließend wird über das Rohr­ teil 4 Druckluft in das Hülsenelement 6 eingeleitet, worauf sich der Mantel 9 aufweitet und an der Innenwandung der Hals­ öffnung des Hohlkörpers 12 anlegt. Damit ist der Hohlkörper 12 erfaßt und kann durch eine vom Trägerkopf 3 durchgeführte Hub­ bewegung und eine anschließende Translationsbewegung zu einer Folgestation, beispielsweise einem Transportband weitergeför­ dert werden. Nach dem Absetzen des Hohlkörpers 12 an der Folge­ station wird der Erfassungsdorn 1 drucklos geschaltet, worauf die Druckluft aus dem Hülsenelement 6 entweicht und der Mantel wieder auf der Außenfläche der Hülse 8 zur Auflage kommt. Die Verbindung des Erfassungsdorns 1 mit dem Hohlkörper 12 ist da­ mit gelöst und der Erfassungsdorn kann zur Ausgangsstation zu­ rückkehren. In operation, the sensing mandrel 1 at an output station, for example on a matte a blow molding machine, to the connection head 3 is lowered vertically into the neck opening of the hollow body 12 until the stop member 7 comes to rest on the upper edge of the neck opening. Subsequently, compressed air is introduced into the sleeve element 6 via the pipe part 4 , whereupon the jacket 9 expands and creates an opening on the inner wall of the neck of the hollow body 12 . So that the hollow body 12 is detected and can be carried out by a lifting movement carried out by the carrier head 3 and a subsequent translation movement to a subsequent station, for example a conveyor belt. After depositing the hollow body 12 at the sequence station, the detection mandrel 1 is depressurized, whereupon the compressed air escapes from the sleeve element 6 and the jacket comes to rest on the outer surface of the sleeve 8 . The connection of the detection mandrel 1 to the hollow body 12 has been released and the detection mandrel can return to the starting station.
