   Antriebsvorrichtung für den Transportwagen einer Maschine zum Schneiden und bzw. oder Schweissen von dünnen Folien oder Folienschläuchen

 dass der Transpoltwagen--2--, wenn er den hinteren Totpunkt seiner Bahn erreicht hat, durch die   Steine--14--,   wenn sie über den halben Umfang der Rollen--22--laufen, seine Bewegungsrichtung umkehrt. Der Transportwagen--2--wird dann in entgegengesetzter Richtung bewegt, bis der   Fortsatz--4--an   den   Anschlag-6--stösst,   wodurch die   Stange-S--   verschoben wird, was zu einer Umsteuerung des Elektromotors führt. Dadurch setzt sich der Transportwagen nach einem kurzen, in seinem vorderen Totpunkt eintretenden Stillstand wieder in Bewegung, und der Vorgang wiederholt sich. 



   Der Hubweg des die Zange tragenden Transportwagens kann je nach der Länge des abzuschneidenden Folienstückes sehr schnell verändert werden. Hiezu genügt es, den   Anschlag--6-   auf der   Stange--8-zu   verstellen. Um die Einstellung zu erleichtern, kann im Weg zwischen dem,   Fortsatz--4--und   dem   Endschalter --10-- eine   Einstellschraube vorgesehen werden, die entweder zwischen dem Fortsatz --4-- und dem Anschlag-6-, diesem und der   Stange--8-,   oder letzterer und dem   Endschalter --10-- angeordnet   ist. 



   In der praktischen Ausführung der Erfindung sind noch verschiedene Sicherungssysteme eingebaut, um mit Sicherheit auszuschliessen, dass, etwa für den Fall eines Versagens des Endschalters   --10-,   Gewähr dafür besteht, dass der Transportwagen--2--trotzdem rechtzeitig im vorderen Totpunkt zum Stillstand kommt.

   Drive device for the transport trolley of a machine for cutting and / or welding thin foils or foil tubes
 EMI1.1

 that the transport car - 2 - when it has reached the back dead center of its path, reverses its direction of movement through the stones - 14 - when they run over half the circumference of the rollers - 22 -. The trolley - 2 - is then moved in the opposite direction until the extension - 4 - hits the stop-6 -, whereby the rod-S - is displaced, which leads to a reversal of the electric motor. As a result, the transport trolley starts moving again after a brief standstill occurring at its front dead center, and the process is repeated.



   The stroke of the transport carriage carrying the pliers can be changed very quickly depending on the length of the piece of film to be cut off. To do this, it is sufficient to adjust the stop - 6- on the rod - 8-. To make the setting easier, an adjusting screw can be provided in the path between the extension - 4 - and the limit switch --10--, which can be inserted between the extension --4-- and the stop 6-, this and the rod - 8-, or the latter and the limit switch --10-- is arranged.



   In the practical embodiment of the invention, various safety systems are also installed in order to rule out with certainty that, for example in the event of a failure of the limit switch -10-, there is a guarantee that the transport trolley - 2 - will nevertheless reach the front dead center in time Standstill comes.

PATENTANSPRUCH : Antriebsvorrichtung für den Transportwagen einer Maschine zum Schneiden und bzw. oder Schweissen von dünnen Folien oder Folienschläuchen, die taktweise zu-und voneinander bewegbare Zangen aufweist, deren Backen in der übergabestellung der Folie ineinandergreifen und eine dieser Zangen auf dem Transportwagen zum Vorziehen der Folie angeordnet ist, d a d u r c h g e k e n n - zeichnet, dass zum Antrieb des die Zange tragenden Transportwagens (2) ein umsteuerbar umlaufendes endloses Zugorgan, z. B. PATENT CLAIM: Drive device for the transport trolley of a machine for cutting and / or welding thin films or film tubes, which has tongs that can be moved in and out of each other in cycles, the jaws of which interlock in the transfer position of the film and one of these tongs is arranged on the transport trolley for pulling the film forward , characterized in that to drive the transport carriage (2) carrying the pliers, a reversible, endless pulling element, e.g. B. Kette oder Seil (16), vorgesehen ist, das zwei mit Abstand und parallel zueinander verlaufende Zugorgantrumpaare (16a, 16b) aufweist, wobei je ein Trum jedes Paares mit gleicher Laufrichtung mit einem in einer quer zu diesem Wagen angeordneten Kulisse (12) verschiebbaren Gleitstein (14) verbunden ist, und dass in an sich bekannter Weise die Umkehrrolle (22) der beiden Zugorgantrumpaare (16a, 16b) den einen Totpunkt des Wagenweges festlegt, wogegen der zweite Totpunkt durch Umsteuerung des Antriebes für das Zugorgan durch einen in der Hubrichtung des Wagens verstellbar angeordneten Anschlag (6), welcher mit einem Endschalter zusammenwirkt, festlegbar ist. Chain or rope (16) is provided which has two pairs of tension members (16a, 16b) that are spaced apart and parallel to one another, with one strand of each pair running in the same direction with a sliding block that can be moved in a slide block (12) arranged transversely to this carriage (14) is connected, and that in a known manner the reversing roller (22) of the two Zugorgantrumppaires (16a, 16b) defines the one dead point of the carriage path, while the second dead center by reversing the drive for the pulling element by one in the stroke direction of the Trolley adjustable stop (6), which interacts with a limit switch, can be fixed.
