KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei Schachtelfaltmaschinen, bei denen das Werkstück durch einen oberen Stempel, der die Form der Schachtel hat, in eine Matrize hineingestoßen wird, in welcher die Schachtelteile miteinander verklebt werden, worauf der Stempel wieder aus der Matrize herausgezogen wird, hat es sich als ein großer Nachteil herausgestellt, daß die gefaltete Schachtel an dem Stempel so fest anhaftet,In box folding machines where the workpiece is passed through an upper punch, the has the shape of the box, is pushed into a die in which the box parts are glued together, whereupon the punch is pulled out of the die again it has been found to be a major disadvantage that the folded box adheres so tightly to the stamp,

ίο daß sie nicht von demselben abzuziehen ist, sondern mit ihm hochgeht. Der Zweck der vorliegenden Erfindung ist, diesen Übelstand dadurch zu vermeiden, daß der Stempel aus einzelnen Backen gebildet wird, welche nach dem Falten der Schachtel mechanisch zusammengezogen werden, so daß der Stempel einen kleineren Raum einnimmt und nunmehr die Schachtel leicht aus der Matrize entfernt werden kann.ίο that it is not to be deducted from the same, but goes up with him. The purpose of the present invention is to remedy this drawback to avoid thereby that the stamp is formed from individual jaws, which after the folding of the box are mechanically pulled together so that the stamp takes up a smaller space and now the box can be easily removed from the die.

Auf der " Zeichnung ist ein derartiger Stempel in Fig. ι und 2 in Ansicht mit abgenommener Deckelplatte dargestellt, während die Fig. 3 und 4 einen senkrechten bezw. wagerechten Schnitt veranschaulichen und die Fig. 5 eine Seitenansicht des Stempels darstellt.On the "drawing is such a stamp in Fig. Ι and 2 in view with removed Cover plate shown, while Figs. 3 and 4 a vertical respectively illustrate a horizontal section and FIG. 5 is a side view of the stamp represents.

Der neue Stempel besteht aus einer Schiene a, die an ihrem unteren Ende zu einer Platte i ausgestaltet ist, ■ an welcher eine Platte b befestigt ist. An dieser Platte sind um Zapfen c drehbar die seitlichen Backen d angeordnet, welche an ihrem dem Drehpunkt entgegengesetzten Ende von Armen e ergriffen werden, die ihrerseits an Stangen f angelenkt sind. Diese Stangen sind an der Platte b.(bl) bezw. Platte i geeignet geführt und mit einem Zapfen k versehen, an welchem eine seine hin- und hergehende Bewegung vermittelnde Stange oder dergl. angekuppelt werden kann.The new stamp consists of a rail a, which is designed at its lower end to form a plate i , to which a plate b is attached. The side jaws d are arranged on this plate so as to be rotatable about pegs c , which are gripped at their end opposite the pivot point by arms e , which in turn are articulated on rods f. These rods are on the plate b. (B l ) respectively. Plate i suitably guided and provided with a pin k , to which a rod or the like which mediates its reciprocating movement can be coupled.

In vorliegendem Beispiel ist der Stempel für eine rechteckige Schachtel gedacht. Die beweglichen Backen d haben deshalb die T-förmige Form erhalten. An ihnen werden die schmalen Seiten der Schachtel gefaltet, während für die anderen breiten Seiten die Platten b und b1 vorgesehen sind, welche mit der Platte i verbunden sind, so daß zwischen den Enden der Platten b, b1 die Bewegung der Backen d erfolgen kann.In the present example, the stamp is intended for a rectangular box. The movable jaws d have therefore been given the T-shape. On them the narrow sides of the box are folded, while for the other broad sides the plates b and b 1 are provided, which are connected to the plate i , so that the movement of the jaws d takes place between the ends of the plates b, b 1 can.

Die Wirkungsweise des neuen Stempels ergibt sich ohne weiteres.The mode of operation of the new stamp is straightforward.

In Fig. 2 ist derselbe in der Stellung veranschaulicht, in welcher das Falten bewerkstelligt wird. Nach erfolgtem Falten und bevor der ganze Stempel wieder hochgeht, wird die Stange f hochgezogen und hierdurch werden, wie Fig. 1 erkennen läßt, die Backen d gedreht, der von dem Stempel vorher eingenommene Raum also verkleinert, wodurch die Schachtel leicht aus der Matrize entfernt werden kann.In Fig. 2 the same is illustrated in the position in which the folding is accomplished. After folding and before the whole punch goes up again, the rod f is pulled up and, as shown in FIG. 1, the jaws d are rotated, thus reducing the space previously occupied by the punch, whereby the box is easily removed from the die can be.

Bei Einnahme der Gebrauchsstellung werden durch die heruntergehenden Stangen f die Arme e gestreckt und hierdurch die Backen d wieder in die Gebrauchslage gedreht.When the position of use is assumed, the arms e are stretched by the rods f going down, thereby turning the jaws d back into the position of use.
