Description

Die Erfindung betrifft eine Verpackungsmaschine mit einer Schneideinrichtung nach dem Oberbegriff des Patentanspruches 1.The invention relates to a packaging machine with a cutting device according to the preamble of claim 1.

Bei einer verpackungsmaschine mit einer Schneideinrichtung wird in bekannter Weise das Widerlager bis zur Ebene der zu trennenden Folie bewegt und dann arretiert. In dieser arretierten Stellung greift das auf der gegenüberliegenden Seite der Folienbahn liegende Messer ein und trennt die Folienbahn in Zusammenwirken mit dem Widerlager durch. Dabei treten unerwünschte Biegekräfte auf, die das Schneideergebnis nachteilig beeinflussen.In a packaging machine with a cutting device, the abutment is moved in a known manner to the level of the film to be separated and then locked. In this locked position, the knife lying on the opposite side of the film web engages and cuts the film web in cooperation with the abutment. Undesirable bending forces occur which adversely affect the cutting result.

Aus der US-A-3 574 291 ist eine Verpackungsmaschine mit einer Schneideinrichtung nach dem Oberbegriff des Patentanspruches 1 bekannt.From US-A-3 574 291 a packaging machine with a cutting device according to the preamble of claim 1 is known.

Aufgabe der Erfindung ist es, die Verpackungsmaschine der eingangs beschriebenen Art so abzuwandeln, daß die Schneideinrichtung derart verbessert wird, daß der beschriebene Nachteil vermieden wird. Diese Aufgabe wird durch eine im Patentanspruch 1 gekennzeichnete Verpackungsmaschine gelöst.The object of the invention is to modify the packaging machine of the type described in the introduction in such a way that the cutting device is improved in such a way that the disadvantage described is avoided becomes. This object is achieved by a packaging machine characterized in claim 1.

Further advantageous features and expediencies of the invention result from the description of an embodiment with reference to the figures. From the figures show:

A side view of a packaging machine with the side cover and omitted
Fig. 2
a side view of a cutting device for such a packaging machine, partly in a sectional view.

Die Verpackungsmaschine weist einen Maschinenrahmen 1 und nacheinander angeordnet eine Formstation 2, eine Evakuier- und Versiegelungsstation 3 und eine Schneideinrichtung 4 auf. In der Verpackungsmaschine wird eine Folienbahn 5 von der Eingangsseite in die Maschine eingeführt. In der Formstation werden aus der Folienbahn Behälter geformt. Diese werden nach dem Befüllen in der Evakuier- und Versiegelungsstation versiegelt und schließlich mittels der Schneideinrichtung 4 voneinander getrennt.The packaging machine has a machine frame 1 and, one after the other, a molding station 2, an evacuation and sealing station 3 and a cutting device 4. A film web 5 is introduced into the machine from the input side in the packaging machine. In the forming station, containers are formed from the film web. After filling, these are sealed in the evacuation and sealing station and finally separated from one another by means of the cutting device 4.

Die Schneideinrichtung umfaßt eine unterhalb der Folienbahn 5 angeordnete Kolben-Zylindereinrichtung 6, die sich im wesentlichen in vertikaler Richtung erstreckt und die einen Zylinder 7 und einen nach oben sich erstreckenden Kolben 8 aufweist. Das obere freie Ende des Kolbens ist als das eigentliche Widerlager 9 für das Messer 12 ausgebildet und besitzt eine Auflagefläche für die Folienbahn 5 mit einem Eintauchschlitz 10 für das Messer 12. Die Kolben-Zylindereinrichtung 6 ist mit einer nicht gezeigten Druckluftquelle verbunden. Die Kolben-Zylindereinrichtung ist so ausgebildet, daß das Widerlager bei Anliegen der dem Zylinder zugeführten Druckluft gerade bis auf die Unterseite der Folienbahn gelangt.The cutting device comprises a piston-cylinder device 6 arranged below the film web 5, which extends essentially in the vertical direction and which has a cylinder 7 and a piston 8 which extends upwards. The upper free end of the piston is designed as the actual abutment 9 for the knife 12 and has a bearing surface for the film web 5 with an immersion slot 10 for the knife 12. The piston-cylinder device 6 is connected to a compressed air source, not shown. The piston-cylinder device is designed in such a way that the abutment just reaches the underside of the film web when the compressed air supplied to the cylinder is applied.

Die Messereinrichtung 11 umfaßt ein Schneidmesser 12, welches unmittelbar oberhalb der Folienbahn 5 und auf der dem Widerlager gegenüberliegenden Stelle liegt. Das eigentliche Messer 12 ist mit einem pneumatik betriebenen Antrieb verbunden, mit Hilfe dessen das Messer zum Schneiden durch die Folienbahn 5 hindurch in den Eintauchschlitz 10 bewegbar und in die zurückgezogene Stelle zurückführbar ist.The knife device 11 comprises a cutting knife 12 which lies directly above the film web 5 and on the point opposite the abutment. The actual knife 12 is connected to a pneumatically operated drive, with the aid of which the knife can be moved through the film web 5 into the immersion slot 10 and can be returned to the retracted position.

Die Kolbenstange 8 weist einen sich senkrecht zu ihrer Achse erstreckenden Schlitz 13 auf. Es ist ein Keil 14 vorgesehen, der in der Richtung senkrecht zur Achse des Kolbens, also in waagerechter Richtung verschiebbar gelagert ist und der auf einer Seite mit einer den Keil in seiner Führung bewegenden Antriebseinrichtung 15 derart verbunden ist, daß der Keil zwischen der in Fig. 2 gezeigten zurückgezogenen Stellung und einer Stellung, bei der der Keil in den Schlitz 13 hinein bewegt ist, hin- und herbewegbar ist. Die Kolbeneinrichtung weist eine Markierung auf. Es ist ein Sensor 17 so angeordnet, daß er die Markierung erfaßt, wenn das Widerlager gerade in der oben beschriebenen ausgefahrenen Stellung ist. Der Ausgang des Sensors ist mit einem Eingang einer Steuerung 18 verbunden. Ein Ausgang der Steuerung ist mit dem Steuereingang der Antriebseinrichtung 15 verbunden. Die schiefe Ebene des Keiles 13 ist so gewählt, daß das dickere Ende des Keiles auf der mit dem Antrieb verbundenen Seite liegt.The piston rod 8 has a slot 13 extending perpendicular to its axis. A wedge 14 is provided which is mounted so as to be displaceable in the direction perpendicular to the axis of the piston, that is to say in the horizontal direction, and which is connected on one side to a drive device 15 which moves the wedge in its guide in such a way that the wedge between the one shown in FIG 2 shown retracted position and a position in which the wedge is moved into the slot 13, can be moved back and forth. The piston device has a marking. A sensor 17 is arranged so that it detects the marking when the abutment is just in the extended position described above. The output of the sensor is connected to an input of a controller 18. An output of the control is connected to the control input of the drive device 15. The inclined plane of the wedge 13 is chosen so that the thicker end of the wedge lies on the side connected to the drive.

Im Betrieb befindet sich der Keil 14 zunächst in der zurückgezogenen Stellung derart, daß die Kolbenstange unbehindert von dem Keil aus ihrer abgesenkten Stellung in die oben beschriebene und in Fig. 2 gezeigte Stellung unmittelbar an der Folienbahn bewegbar ist. Sobald der Sensor 17 durch Erfassen der Markierung feststellt, daß diese Stellung erreicht ist, wird über die Steuerung 18 die Antriebseinrichtung 15 eingeschaltet, wodurch der Keil in den Schlitz bewegt und damit eine zusätzliche mechanische Kraft in Richtung auf die Folienbahn ausgeübt wird, so daß diese um ein kleines Stück nach oben vorgespannt wird. Der Keil bleibt dann arretiert, bis der eigentliche Schneidvorgang durch Eintauchen des Messers 12 erfolgt ist. Dabei wird die dabei entstehende Kraft nicht auf die Kolben-Zylindereinrichtung sondern auf den Keil beziehungsweise das diesen tragene Widerlager 19 übertragen.In operation, the wedge 14 is initially in the retracted position such that the piston rod can be moved freely on the film web from the lowered position into the position described above and shown in FIG. 2. As soon as the sensor 17 determines by detecting the mark that this position has been reached, the drive device 15 is switched on via the control 18, as a result of which the wedge moves into the slot and thus an additional mechanical force is exerted in the direction of the film web, so that the latter around a little bit is biased upwards. The wedge then remains locked until the actual cutting process has taken place by immersing the knife 12. The force generated is not transmitted to the piston-cylinder device but to the wedge or the abutment 19 carrying it.
