Description
Von einer nicht dargestellten Abwickeleinrichtung oder einem Extruder wird der Bearbeitungsstelle eine Materialbahn 13 mit konstanter Geschwindigkeit zugeführt (F i g. 1). Dabei wird die Zuführgeschwindigkeit über eine aus einer Tänzerrolle 44 mit Schwenkarm 49 und Potentiometer 52 bestehende Regeleinrichtung konstant gehalten. Von hier läuft die Materialbahn über eine Führungsrolle 8 und eine Umlenkrolle 4, an der aus dem Stempel 24 und dem Gegenlager 22 bestehenden Bearbeitungsstelle vorbei über Spannwalzen 82, 84, 86 zur zweiten Bearbeitungsstelle mit dem Stempel 24' und. von hier über die zweite Umlenkrolle 6 zur Ausgabe mit einer weiteren Führungsrolle 10 und der Abzugswalze 18. Die Umlenkrollen 4 und 6 werden hierbei von einem in und entgegen der Förderrichtung der Materialbahn periodisch bewegten Schlitten 2 getragen, während die Führungsrollen8 und 10 sowie die Walzen 82, 84 und 86 in der Maschine ortsfest gelagert sind. Über die Walzen 8, 4, 82, 84, 86, 6, 10 läuft synchron mit und parallel zur Materialbahn eine in sich geschlossene Synchronisierkette 21, so daß sich bei unbewegtem Schlitten sämtliche Rollen bzw. Walzen syn chron drehen müssen. From an unwinding device (not shown) or an extruder the processing point is a material web 13 at constant speed supplied (Fig. 1). The feed speed above one consisting of a dancer roller 44 with pivot arm 49 and potentiometer 52 Control device kept constant. From here the material web runs over a guide roller 8 and a pulley 4, on which the punch 24 and the counter bearing 22 exist Processing point past via tension rollers 82, 84, 86 to the second processing point with the stamp 24 'and. from here via the second pulley 6 to the output a further guide roller 10 and the take-off roller 18. The deflection rollers 4 and 6 are periodic by one in and against the conveying direction of the material web moving carriage 2 carried while the guide rollers 8 and 10 and the rollers 82, 84 and 86 are fixedly mounted in the machine. About the rollers 8, 4, 82, 84, 86, 6, 10 runs synchronously with and parallel to the material web a self-contained one Synchronizing chain 21, so that when the carriage is stationary, all rollers or Rolls must rotate synchronously.
Der die Rollen 4 und 6 tragende Schlitten 2 wird periodisch hin- und herbewegt mit einer auf die Fördergeschwindigkeit der Materialbahn 13 abgestimmten Geschwindigkeit. Wenn sich beispielsweise der Schlitten 2 entgegen der Förderrichtung, das ist in der Zeichnung nach rechts, mit einer der halben Fördergeschwindigkeit der Materialbahn 13 entsprechenden Geschwindigkeit bewegt, ist der zwischen den Umlenkrollen4 und 6 befindliche Abschnitt der Materialbahn relativ zur Maschine vorübergehend stillgesetzt. Während dieser Zeit werden die Bearbeitungsstempel 24 und 24' nach unten gegen die Materialbahn 13 bewegt und bearbeiten diese in gewünschter Weise. Wenn der Schlitten 2 darauf in umgekehrter Richtung, also in Förderrichtung der Materialbahn 13 bzw. in der Zeichnung nach links bewegt wird, wird der zwischen den Umlenkrollen 4 und 6 befindliche Bahnabschnitt mit hoher Geschwindigkeit abgezogen. Die Bearbeitungsstempel 24, 24' befinden sich hierbei in Ruhestellung. Der von der Abzugswalze 18 abgezogene Abschnitt der Materialbahn 13 bewegt sich hingegen kontinuierlich mit der eingangsseitigen Fördergeschwindigkeit. The carriage 2 carrying the rollers 4 and 6 is periodically and moved at a speed that is matched to the conveying speed of the material web 13 Speed. If, for example, the carriage 2 moves against the direction of conveyance, this is to the right in the drawing, at half the conveyor speed the material web 13 corresponding speed moves, is that between the Deflection rollers 4 and 6 located section of the material web relative to the machine temporarily shut down. During this time, the processing punches 24 and 24 'moved downwards against the material web 13 and process it in the desired manner Way. When the carriage 2 then moves in the opposite direction, that is, in the conveying direction the web of material 13 or is moved to the left in the drawing, the between the pulleys 4 and 6 located web section withdrawn at high speed. The processing punches 24, 24 'are here in the rest position. The one from the On the other hand, the portion of the material web 13 withdrawn from the pull-off roller 18 moves continuously with the conveying speed on the input side.
Mittels der Walzen 82, 84, 86 wird eine gleichmäßige Spannung der Materialbahn an den Bearbei- tungsstellen gewährleistet. Ferner bilden sie eine Art Speicher, mittels dessen der Abstand der zu bearbeitenden Stellen der Materialbahn 13 einstellbar ist. By means of the rollers 82, 84, 86, a uniform tension of the Material web to the processing management offices guaranteed. They also form a species Memory, by means of which the distance between the areas of the material web to be processed 13 is adjustable.
Sie stehen still, während die Bahn an den Bearbeitungsstellen etillgesetzt ist und fördern diese mit hoher Geschwindigkeit bei einer Bewegung des Schlittens 2 nach links.They stand still while the web is set at the processing stations is and convey this at high speed when the carriage moves 2 to the left.
Sollte die bearbeitete Materialbahn 13 einer intermittierenden Ausgabevorrichtung, beispielsweise mit einer Abschneideeinrichtung, zugeführt werden, so könnte die Walze 84 als Steuerwalze mit einer ausgangsseitigen Abzugswalze verbunden werden wie dies aus F i g. 2 ersichtlich ist. Should the processed material web 13 of an intermittent output device, for example with a cutting device, the Roller 84 can be connected as a control roller with an output-side take-off roller as shown in FIG. 2 can be seen.
Beim Ausführungsbeispiel nach F i g. 2 ist nur eine Bearbeitungsstelle vorgesehen, jedoch kann natürlich eine beliebige Anzahl hiervon in ähnlicher Weise wie in F i g. 1 vorgesehen sein. F i g. 2 zeigt, daß die Materialbahn 13, welche um die Führungsrolle8 und die Umlenkrolle 4 unter den Bearbeitungsstempel 24 hindurchgeführt worden ist, nicht mehr um die Umlenkrolle 6 läuft, sondern unmittelbar zu einer intermittierenden Ausgabevorrichtung. Dabei wird sie durch die Abzugswalzen 87 und 89 unter Spannung gehalten, ähnlich wie dies bei den Walzen 82, 84, 86 in F i g. 1 der Fall war, und zugleich abgezogen. In the embodiment according to FIG. 2 is only a processing point are provided, but of course any number of these can be similarly provided as in Fig. 1 may be provided. F i g. 2 shows that the web of material 13, which passed around the guide roller 8 and the deflection roller 4 under the processing punch 24 has been, no longer runs around the pulley 6, but directly to one intermittent output device. It is through the take-off rollers 87 and 89 held under tension, similar to the rollers 82, 84, 86 in FIG. 1 was the case and withdrawn at the same time.
Schließlich läuft die Bahn 13 an den Abzugswalzen 87, 89 vorbei zur Schneideeinrichtung 91, durch welche sie in Stücke geschnitten wird.Finally, the web 13 runs past the take-off rollers 87, 89 to Cutter 91 by which it is cut into pieces.
Hierbei sind die Abzugswalzen 87, 89 über die Ketten 21', 21" mit der Synchronisierkefle 21 antriebsmäßig verbunden. Zur Synchronisation der Bewegung von Materialbahn 13 und Abzugswalzen 87, 89 dienen die Steuerwalze 85 und gegebenenfalls die Leerlaufwalzen 85', 85" (Fig.3). Auf diese Weise ist gewährleistet, daß die Umfangsgeschwindigkeit der Abzugswalze 87 und die Oberflächengeschwindigkeit der Materialbahn an der Bearbeitungsstelle stets gleich sind und keine Spannungen entstehen können. Here, the take-off rollers 87, 89 are with the chains 21 ', 21 " the Synchronisierkefle 21 drivingly connected. To synchronize the movement of the web of material 13 and take-off rollers 87, 89 serve the control roller 85 and possibly the idle rollers 85 ', 85 "(Fig.3). In this way it is ensured that the Peripheral speed of the take-off roller 87 and the surface speed of the The material web at the processing point is always the same and no tension arises can.
Die Abschneideeinrichtung 91 schließlich ist mit dem Bearbeitungsstempel 24 synchronisiert, indem beide Teile über Hebel 93 von einem hydraulischen Zylinder 16 betätigt werden, welcher mittels eines mit der Bewegung des Schlittens 2 synchronisierten Nockenantriebs 26 gesteuert wird. Finally, the cutting device 91 is with the processing punch 24 synchronized by both parts via lever 93 of a hydraulic cylinder 16 are actuated, which is synchronized with the movement of the carriage 2 by means of a Cam drive 26 is controlled.
