Description
Anlage 1 zum Schreiben vom 22.6.1959 in Sachen B 35 283/39a Gm Vorrichtung zum Schneiden von dünnen Kunststoff-Folien Gegenstand des vorliegenden Gebrauchsmusters ist eine Vorrichtung zum Schneiden von dünnen Kunststoff-Folien, die gekennzeichnet ist durch eine Zuführ-Vorrichtung, die die Folie in den Apparat einführt, eine Spannvorrichtung, durch die die Folie während des Schneidvorganges gespannt wird, ein Schneidmesser, das mit seiner Schneidkante schräg wie ein Schermesser eingestellt ist, so daß der Schneidvorgang stets punktförmig erfolgt, einen dünnen Schlitz, über den die Folie während des Schneidvorganges gespannt ist sowie durch eine Vorrichtung zum Abtransportieren der geschnittenen Folien. Die Schneidvorrichtung besteht zweckmäßig aus mehreren Teilmessern, die derart angeordnet sind, daß die Spitzen aller Teilmesser gleichzeitig auf die Folie auftreffen und der Schlitz nach dem Durchschneiden der Folie die Schneidkanten aller Teilmesser aufnimmt. Die Spannvorrichtung besteht zweckmäßig auf der einen Seite aus zwei Walzen, durch die die Folie von der Spule abgezogen und vorwärts geführt wird, und auf der anderen Seite aus mindestens einem mit dem Messerbalken verbundenen Niederhalter.Annex 1 to the letter dated June 22, 1959 in the matter of B 35 283 / 39a Gm device for cutting thin plastic films is the subject of the present utility model is a device for cutting thin plastic films, which is marked is a tensioning device through a feeding device that feeds the film into the apparatus, through which the film is stretched during the cutting process, a cutting knife, which is set with its cutting edge at an angle like a shear knife, so that the The cutting process is always punctiform, a thin slit through which the film is tensioned during the cutting process and by a device for transporting it away of the cut foils. The cutting device expediently consists of several Part knives which are arranged in such a way that the tips of all part knives at the same time hit the foil and the slot after cutting through the foil the cutting edges all partial knife takes up. The jig is expediently on one Side of two rollers through which the film is pulled off the spool and forward and on the other side of at least one with the cutter bar connected hold-down device.
Wenn Folien mit einem relativ hohen Elastizitätsgrad geschnitten werden sollen, bietet die.....When cutting films with a relatively high degree of elasticity should, offers the .....
Folie beim Schneiden mit einem längeren Schneidmesser einen relativ hohen Widerstand, während bei der Verwendung einer aus mehreren Teilmessern bestehenden Vorrichtung leicht an denjenigen Stellen wo die Teilmesser aneianderstoßen, Brücken aus Folienmaterial stehenbleiben, da ein vollständiges Übereinandergreifen der einzelnen Teilmesser nicht ohne weiteres erreichbar ist. Die erwähnten Brücken besitzen nur eine sehr geringe Breite ; ihre Beseitigung führt aber bei stark elastischen Folien zu Schwierigkeiten. Die vorliegende Vorrichtung soll in besonderem Maße zum Schneiden von hoch-elastischen Folien dienen und den Schneidvorgang bei Folien der erwähnten Art in einwandfreier Weise durchführen.Foil when cutting with a longer cutting knife a relative high resistance, while when using a multi-section knife Device lightly at those points where the partial knives meet, bridges from film material remain, as a complete overlap of the individual Part knife is not easily accessible. The bridges mentioned only own a very narrow width; however, they can be eliminated in the case of highly elastic films to trouble. The present device is particularly intended for cutting of highly elastic foils are used and the cutting process in foils of the mentioned Kind of performing in an impeccable manner.
Um diese Aufgabenstellung zu lösen, sind die Messerbalken bei der
vorliegenden Vorrichtung in Schnittrichtung beweglich angeordnet und werden während
des Schneidvorganges derart in Schnittrichtung bewegt,
Der Messerbalken ist an auf-und abwärtsgehenden Kolben beweglich angeordnet. Bei der Kolbenbewegung gleitet eine Ablaufrolle an einer schrägen Fläche vorbei und gibt so dem Messer während des Schnittes eine bogenförmige Bewegung, während das Messer bei der Rückbewegung durch am entgegengesetzten Ende angeordnete Federn wieder in die Ausgangsstellung zurückgedrückt wird.The cutter bar is movably arranged on pistons moving up and down. When the piston moves, a run-off roller slides past an inclined surface and gives the knife an arcuate movement during the cut, while the knife on the return movement by arranged at the opposite end Springs is pushed back into the starting position.
In den Figuren bedeutet (1) den Kolben für die Auf-und Abwärtsbewegung im Zylinder ; (2) den Zylinder ; (3) den Messerbalken mit den Messern ; (4) die Ablaufrolle ; (5) eine schräge Fläche für den Hub der Seitwärtsbewegung ; (6) die Brücke für die Verbindung der Kolben (1) ; (7) die Gleitschienen für den Messerbalken ; (8) die Rückholfedern für den Messerbalken ; (9) 2 Niederhalter zum Anpressen und Spannen der Folie während des Schnittes.In the figures, (1) means the piston for the upward and downward movement in the cylinder; (2) the cylinder; (3) the cutter bar with the knives; (4) the Run-off role; (5) an inclined surface for the stroke of the sideways movement; (6) the Bridge for connecting the pistons (1); (7) the slide rails for the cutter bar ; (8) the return springs for the cutter bar; (9) 2 hold-down clamps for pressing on and tensioning the film during the cut.
Bei der Figur 1 ist der Messerbalken, wie bereits erwähnt, oberhalb des Auflagetisches (9) angeordnet. Die Ablaufrolle (4) läuft während des Schneidvorganges an--der schrägen Fläche (5) vorbei und drückt den Messerbalken mit den Messern (3) nach rechts. Die Federn (8) und (9) drücken den Messerbalken (3) beim Aufwärtsgang wieder in die Ausgangsstellung nach links.In FIG. 1, the cutter bar is, as already mentioned, above of the support table (9) arranged. The drain roller (4) runs during the cutting process - past the inclined surface (5) and press the knife bar with the knives (3) To the right. The springs (8) and (9) press the cutter bar (3) during upward gear back to the starting position to the left.
Zur Figur 2 ist folgendes zu bemerken : Die Anordnung des Messerbalkens (7) ist unterhalb des Auflagetisches (9). Bei der Abwärtsbewegung der Kolben (1) wird mittels Kipphebel (2) der Kolben (3) durch den Kolben (4) nach oben betätigt und der Messerbalken (7) an einer schrägen Fläche (5) mittels einer Umlenkrolle (6) seitwärts geschoben. Dadurch treten die Messer durch einen im Auflagetisch (9) angebrachten kleinen Schlitz.The following should be noted about FIG. 2: The arrangement of the cutter bar (7) is below the support table (9). When the pistons (1) move down the piston (3) is actuated upwards by the piston (4) using the rocker arm (2) and the cutter bar (7) on an inclined surface (5) by means of a pulley (6) pushed sideways. This will cause the knives to pass through you in the Small slot attached to the support table (9).
Während der Abwärtsbewegung der Kolben (1) werden gleichzeitig 2 Niederhalter (8), die vor und hinter dem Schlitz im Auflagetisch angeordnet sind, auf den Auflagetisch aufgepreßt, wodurch die Folie gespannt und der Schneidvorgang bewerkstelligt wird.During the downward movement of the pistons (1), 2 hold-down devices are released at the same time (8), which are arranged in front of and behind the slot in the support table, on the support table pressed on, whereby the film is stretched and the cutting process is accomplished.
Sowohl bei der Anordnung der Figur 1 als auch der Anordnung der Figur 2 wird mittels den in Schnittrichtung verschiebbaren Messern eine bogenförmige Schneidbewegung ausgeführt, wobei insbesondere bei elastischen Folien die kleinen Zwischenräume zwischen den einzelnen Stößen der im Messerbalken angebrachten Messer überbrückt werden. Schutzansprüche :Both in the arrangement of Figure 1 and the arrangement of the figure 2, an arcuate cutting movement is created by means of the blades, which can be moved in the cutting direction executed, especially in the case of elastic foils, the small spaces bridged between the individual joints of the knives mounted in the cutter bar will.
