Die Erfindung beziehü sich auf eine Flaschenblasemaschine für Handbetrieb, im besonderen auf die Ausbildung der Fertigblasevorrichtung. Sie bezweckt die Ausbildung der Fertigblasevorrichtung in solcher Weise, daß durch Betätigung eines einzigen Handhebels die Hälften der Fertigform um das an der Kopfform hängende Külbel herumgelegt und verriegelt und in gleichem Schritt hiermit der BlasekopfThe invention relates to a bottle blowing machine for manual operation, in particular on the formation of the blow molding device. Its purpose is the formation of the ready-made blowing device in such a way that the halves are formed by actuating a single hand lever The finished form is placed around the parison hanging on the head form and locked and in the same step the bubble head

ίο auf die Kopfform niedergedrückt werden kann. Es ist zwar bereits eine Fertigblasevorrichtung bekannt, bei welcher von ein und demselben Handhebel aus sowohl der Blasekopf auf die Fertigform aufgedrückt als auch die Blaseform verriegelt werden kann. Hierbei mußten aber zuvor die beiden Hälften der offenstehenden Fertigform ergriffen und um das Külbel zusammenbewegt werden. Dieser besondere Handgriff fällt bei der Einrichtung gemäß vorliegender Erfindung weg, da auch das Zusammenbewegen der Fertigformhälften in einem Zuge mit den anderen Vorgängen durch den Handhebel bewirkt wird.ίο can be pressed down on the head shape. Although a ready-made blow molding device is already known in which one and the same Hand lever from both the blow head pressed onto the finished mold and the blow mold can be locked. Before doing this, however, the two halves of the open The finished form is gripped and moved around the parison. This particular handle falls in accordance with the establishment present invention away, since the moving together of the finished mold halves in one Train with the other operations is effected by the hand lever.

Die Einrichtung gemäß der Erfindung kann daher' auch von Einarmigen, etwa Kriegsinvaliden, bedient werden, für welche es sehr schwierig wäre, die beiden Hälften der offenstehenden Fertigform zusammenzuholen und danach, gleichzeitig mit der Niederbewegung des Blasekopfes, zu verriegeln, wie dies bei der bekannten Anordnung notwendig ist.The device according to the invention can therefore 'also be used by one-armed people, such as war invalids, for whom it would be very difficult to use the two halves of the open Bring the finished form together and then, at the same time as the downward movement of the blow head, lock it, as in the known arrangement is necessary.

Es sind auch Glasblasemaschinen bekannt, bei welchen durch ein und denselben Handhebel, und zwar durch den Steuerhebel eines Druckluftantriebszylinders, gleichzeitig die Fertigformhälften um das Külbel geschlossen und der Blasekopf auf die Fertigform niedergeführt wird. Hierbei fand aber keine Verriegelung der Fertigform statt. Die Hälften dieser Form wurden vielmehr unstarr durch den im Druckluftzylinder herrschenden Druck zusammengehalten.There are also known glass blowing machines in which one and the same hand lever, namely by the control lever of a compressed air drive cylinder, at the same time the finished mold halves closed around the parison and the bubble head lowered onto the finished form will. In this case, however, the finished form was not locked. The halves Rather, this shape became inflexible due to the pressure prevailing in the compressed air cylinder held together.

In beiliegender Zeichnung ist die Maschine in einer Ausführungsform beispielsweise dargestellt. In the accompanying drawing, the machine is shown in one embodiment, for example.

Die Maschine hat einen Tisch 1, auf welchem die Motzform 2 steht, in welcher in bekanntef Weise durch den Handhebel 3 in Verbindung mit dem Saugzylinder 4 das eingeschnittene oder gegossene Glas angesaugt und vorgeblasen wird. Ist dieses geschehen, so wird die Motzform 2 geöffnet und in bekannter Weise der vorgearbeitete Glaskörper durch die Mundstückzange 5 in die Gabel 6 der Fertigblaseeinrichtung eingehängt. An dem Handhebel 7, welcher mit der Preßlufteinlaßspindel 8 beweglich verkuppelt ist, ist eine Kette 9 oder Seil angebracht, welche wieder mit dem Gewichtshebel 10, Einrichtung zum Schließen und Verriegeln der Fertigform, verbunden ist. Diese Einrichtung besteht zunächst aus den Winkelhebeln. 11, ii_a, 12 und 12_a. Diese lagern beweglich auf dem auf die Spindel. 13 gesteckten Futter 14. Mit den Winkelhebeln 11, 11 _a, 12The machine has a table 1 on which the Motzform 2 stands, in which the cut or cast glass is sucked in and pre-blown in a known manner by the hand lever 3 in connection with the suction cylinder 4. Once this has happened, the Motzform 2 is opened and the pre-machined glass body is suspended in the known manner by the mouthpiece pliers 5 in the fork 6 of the finished blowing device. On the hand lever 7, which is movably coupled to the compressed air inlet spindle 8, a chain 9 or rope is attached, which is again connected to the weight lever 10, means for closing and locking the finished mold. This device initially consists of the angle levers. 11, ii _a , 12 and 12 _a . These are moveable on the spindle. 13 inserted chuck 14. With the angle levers 11, 11 _a , 12

Claims

and Ι2 _Λ are eccentric rings 15 and 16

, kig connected, which by the eccentric 17, which has its bearing in the arms 18 of the stand 13 are actuated. The eccentric 17 is firmly connected to a one-armed lever 19, which by joint parts 20 of the Weight lever 10 is given a reciprocating motion, depending on the Chain 9 pulled up or down by the hand lever 7. Below the Air inlet spindle 8 is located the blow nozzle 21. On the weight lever 10 is located the loading weight 27. With the arms 11 and 12 of the angle lever are connecting rods 22 and 23, which engage in the eyelets 24 and 25 of the finished blow mold 26.

The process is as follows:

As soon as the ring pliers 5 with the glass bulb attached has been pushed into the open ready-made bubble mold 26 (FIG. 2), held by the fork 6 (FIG. 1), the hand lever 7 is pressed down. As a result, the lever 10, which is connected to the hand lever 7 by the chain 9, will also go down due to the load of the weight 27. By lowering the lever 10, the joint parts 20; 19 is actuated and with it also the eccentric 17, which thereby pushes the angle levers 11, ττ _α , i2 and I2 _a connected to the eccentric rings 15 and 16 away from itself and closes the finished blow mold 26 (FIG. 3).

When setting the machine, the distance between the ring pliers 5 and the blow head 21 is chosen far enough, before the blower head 21 is seated on the ring pliers 5 the ready-made bubble mold should already be closed. Then the bubble head 21 sits on the ring pliers 5, the chain 9 will hang down completely loosely (Fig. 5). This one has that Advantage that the finished blow mold 26 is closed nicely before the compressed air in the preprocessed Vitreous can enter. When the hand lever 7 is lifted, the bubble head 21 is then also only removed from the ring pliers 5 lift off before the finished bubble mold 26 opens again. The fact that the Closing the finished blow mold 26 puts the eccentric on the dead center (Fig. 3), can the finished blow mold 26 are not pushed apart by the action of the compressed air, but is locked.

Pate nt-An S ρ RU c pi: '

Bottle blowing machine for manual operation, in which one and the same hand lever from both the blow head and the blow mold pressed onto the finished mold is closed, characterized in that an eccentric (15, 16, 17), wel- ' Ches close the bubble mold (26) under the influence of a load (weight 27) and can lock in the closed position at its dead center position with the bubble head (21) or its drives unstable (e.g. by chain 9) and so connected is that when the bubble head is raised, the non-rigid connection is the one driving the eccentric Load continues, but it releases when the bladder head is lowered, like this that the bubble mold is closed and locked.
