Abstract
Description
Die Erfindung betrifft eine Blasformmaschine gemäß Oberbegriff des Anspruchs 1.The invention relates to a blow molding machine according to the preamble of claim 1.
Bei bekannten Vorrichtungen dieser Art werden die in der Blas form geblasenen Hohlkörper von einer Stanzmaske übernommen, die an den Stellen des Hohlkörpers, an denen sich abzutrennende Ab fälle, wie z. B. Hals-, Griff- und Bodenbutzen, befinden, Aus nehmungen für den Durchtritt der Stanzmesser aufweisen. Nach teilig ist dabei, daß bei einer Umstellung auf ein anderes Blasprodukt sowohl die Stanzmasken als auch die Stanzmesser je weils gesondert auszuwechseln sind. Da die Stanzmesser maschi nengestellfest angeordnet sind, ergibt sich ferner der Nach teil, daß die Stanzmesser bei jeder Umrüstung der Blasformma schine auf die Stanzmasken einjustiert werden müssen.In known devices of this type, those in the blow shape-blown hollow body taken from a punch mask that at the locations of the hollow body where the Ab to be separated cases such as B. neck, grip and floor slugs are located, off have recesses for the passage of the punching knife. After Part of it is that when switching to another Blown product both the cutting masks and the cutting knives each because they have to be replaced separately. Since the punching knife is machi Are arranged fixed to the frame, there is also the after part that the punch knife every time the blow molding must be adjusted to the punching masks.
Aufgabe der Erfindung ist es, eine Transportvorrichtung der ge nannten Art zu schaffen, die bei der Umrüstung der Blasformma schine von einem Blasprodukt auf ein anderes nur einen geringen Umstellungsaufwand erfordert. The object of the invention is to provide a transport device of the ge called type to create, when converting the blow molding Shine from one blow product to another is only a small one Changeover effort required.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale aus dem Anspruch 1 gelöst.This object is achieved by the characterizing Features solved from claim 1.
Die Erfindung wird im folgenden anhand eines Ausführungsbei spiels näher erläutert.The invention is illustrated below with the aid of an embodiment explained in more detail.
Es zeigt:It shows:
Fig. 1 die Ansicht auf die Trennfugen einer Blasformmaschine mit davor angeordneter Stanzmaskeneinheit und damit verbunde ner Stanzmessereinrichtung, FIG. 1 shows a view of the joints of a blow molding machine with front arranged matte unit and in related punching knife means
Fig. 2 die Draufsicht auf die Stanzmaskeneinheit nach Fig. 1 und Fig. 2 is a plan view of the punch mask unit according to Fig. 1 and
Fig. 3 die Schnittansicht gemäß der Schnittlinie A-A in Fig. 2. Fig. 3 is a sectional view according to the section line AA in FIG. 2.
Die Fig. 1 bis 3 zeigen eine Blasform mit zwei Blasformhälf ten 1 und 2 sowie eine Stanzmaske mit zwei Stanzmaskenhälften 3 und 4 in geschlossenem Zustand. An der Stanzmaskenhälfte 4 sind zwei Führungssäulen 5 und 6 befestigt, die eine Trägerplatte 7 für ein oberes und ein unteres Stanzmesser 8 und 9 durchsetzen. An der Trägerplatte 7 ist ferner der Zylinder 10 einer An triebseinheit für die Stanzmesser 8 und 9 befestigt, in dem ein Kolben (nicht dargestellt) geführt ist, dessen Kolbenstange 11 fest mit der Stanzmaskenhälfte 4 verschraubt ist. An der Stanz maskenhälfte 3 ist ein Gegenmesser 12 befestigt, das dem unte ren Stanzmesser 9 zugeordnet ist. Figs. 1 to 3 show a blow molding mold having two Blasformhälf th 1 and 2 and a punching mask with two matte halves 3 and 4 in the closed state. On the punch mask half 4 , two guide columns 5 and 6 are attached, which pass through a carrier plate 7 for an upper and a lower punch knife 8 and 9 . On the support plate 7 , the cylinder 10 is also attached to a drive unit for the punching knives 8 and 9 , in which a piston (not shown) is guided, the piston rod 11 of which is firmly screwed to the punch mask half 4 . On the punch mask half 3 , a counter knife 12 is attached, which is assigned to the punch punch 9 unte ren.
In Fig. 3 ist in strichpunktierten Linien ein geblasener Hohl körper in der Form einer Flasche 13 dargestellt, an der sich an dessen Boden ein Bodenbutzen 14 und an dessen Halsteil ein Halsbutzen 15 befinden. Die Flasche 13 ist teilweise auch in Fig. 1 zu ersehen, in der in strichpunktierten Linien die vor derste Stellung der Stanzmesser 8 und 9 sowie der Trägerplatte 7 und des Zylinders 10 dargestellt sind. In dieser Stellung der Stanzmesser sind der Halsbutzen (15) und der Bodenbutzen 14 be reits entfernt.In Fig. 3, a blown hollow body in the form of a bottle 13 is shown in dash-dotted lines, on the bottom of which there is a floor slug 14 and on the neck part of a neck slug 15 . The bottle 13 can also be seen in part in FIG. 1, in which the dotted lines 8 and 9 as well as the carrier plate 7 and the cylinder 10 are shown in dash-dotted lines. In this position, the punch knife, the neck piece ( 15 ) and the bottom piece 14 are already removed.
Der Zylinder 10 ist vorzugsweise ein Druckluftzylinder der über eine flexible Druckluftleitung (nicht dargestellt) angesteuert werden kann.The cylinder 10 is preferably a compressed air cylinder which can be controlled via a flexible compressed air line (not shown).
Die mit den Bezugszeichen 3 bis 12 versehenen Bauteile stellen erfindungsgemäß eine als Ganzes auswechselbare Baueinheit dar, durch die der Umrüstvorgang einer Blasformmaschine erheblich erleichtert und verkürzt werden kann. According to the invention, the components provided with the reference numerals 3 to 12 represent a unit which can be replaced as a whole and by means of which the changeover process of a blow molding machine can be considerably simplified and shortened.
In einer vorteilhaften Ausführungsform umfaßt die die Stanzmas ken und die Stanzmesser enthaltende Baueinheit auch die Blas form, wodurch für eine Anzahl von Funktionseinheiten nur ein Umrüstvorgang durchzuführen ist.In an advantageous embodiment, it comprises the punching dies ken and the unit containing the punching knife also the blow form, which makes for a number of functional units only one Conversion process must be carried out.
