Description

Rollenschere für Hand- und Kraftbetrieb zum Zerschneiden von Papier, Tuch und anderen Stoffbahnen Es sind bereits Rollenscheren zum Schneiden von Papier und Tuch bekannt, bei welchen als Schneidwerkzeug ein umlaufendes Messer verwendet wird. Die Scheren haben jedoch den Nachteil, daß eine zum einwandfreien Schneiden der Stoffbahn u. dgl. notwendige Vorspannung nicht durch die Schneidvörrichtung selbst erzeugt wird, vielmehr das Gut während des Schneidens von Hand gespannt gehalten werden muß. Um diesen Mangel zu beheben, ist erfindungsgemäß das Schneidmesser zwischen zwei als Laufrollen dienenden Rollen derart angeordnet, daß das Messer mit einem gleichzeitig als Gegenmesser dienenden Greifer gegenüber den Laufrollen in der Höhe versetzt liegt, so daß das über den Greifer und unter den Laufrollen geführte zu schneidende Gut durch die Auflage der Laufrollen auf der Unterlage während des Schneidens gespannt ist.Roller shears for manual and power operation for cutting paper, Cloth and other lengths of fabric There are already roller scissors for cutting paper and cloth are known in which a rotating knife is used as a cutting tool will. However, the scissors have the disadvantage that one for perfect cutting the fabric web and the like. Necessary pre-tensioning is not due to the cutting device itself is generated, rather the material is held taut by hand during cutting must become. In order to remedy this deficiency, according to the invention, the cutting knife is between two serving as rollers rollers arranged so that the knife with a at the same time serving as a counter knife gripper opposite the rollers in height is offset so that the guided over the gripper and under the rollers cutting material due to the rollers resting on the surface during cutting is excited.

Rollen, Messer und Greifer sind an einem einarmigen handgriffartig ausgebildeten Hebel angeordnet, so daß je nach Schrägstellung des Hebels die zum einwandfreien Schneiden notwendige Vorspannung des Schneidgutes je nach Bedarf geregelt werden kann. Gleichzeitig ist durch diese Anordnung ein Zerreißen des Gutes vermieden.Rollers, knives and grippers are like a handle on a one-armed handle trained lever arranged so that depending on the inclination of the lever to flawless cutting, the necessary pre-tensioning of the material to be cut is regulated as required can be. At the same time, this arrangement prevents the goods from tearing apart.

Die Zeichnung zeigt .eine beispielsweise Ausführungsform des Erfindungsgegenstandes für Hand- und Motorantrieb, und zwar zeigt Abb. r die Schere im Schnitt C-D (seitlich gesehen), Abb. a die Schere im Schnitt A -B '(in Stirnansicht), Abb.3 die Schere im Schnitt E'-F (von oben gesehen), Abb. q. die Schere im Schnitt G-H (seitlich gesehen), Abb.,5 die Schere im Schnitt 1-K (in Stirnansicht), Abb.6 die Schere im Schnitt L-M (von oben gesehen).The drawing shows an exemplary embodiment of the subject matter of the invention for manual and motor drive, namely Fig.r shows the scissors in section C-D (side seen), Fig. a the scissors in section A -B '(in front view), Fig. 3 the scissors in section E'-F (seen from above), Fig. q. the scissors in section G-H (on the side seen), Fig. 5 the scissors in section 1-K (in front view), Fig. 6 the scissors in Section L-M (seen from above).

Die beiden Führungsrollen b, und b2 und das Kreismesser d sind mit der Welle c fest verbunden, während der als Gegenmesser dienende Greifer e an dem Handgriff a angeschraubt ist. Drückt man nun mit dem Handgriff a bei entsprechender Schrägstellung die Schere gegen ihre Unterlage, so rollen sich die Rollen b1 und b2 auf der Unterlage ab, wodurch zwischen dem mit der Welle c umlaufenden Kreismesser und dem feststehenden Gegenmesser e eine Schneidwirkung erzeugt wird. Das Messer d kann mittels der Muttern/ und g genau an den Greifer e anliegend eingestellt und in seitlicher Richtung fixiert werden. Der Greifer e dient als Aufnehmer und Unterlage für den zu schneidenden Stoff.The two guide rollers b and b2 and the circular knife d are firmly connected to the shaft c, while the gripper e serving as a counter knife is screwed to the handle a. If you now press the scissors against their base with the handle a with the appropriate inclination, the rollers b1 and b2 roll on the base, creating a cutting effect between the circular knife rotating with the shaft c and the stationary counter knife e. The knife d can be adjusted exactly against the gripper e by means of the nuts / and g and fixed in the lateral direction. The gripper e serves as a pick-up and base for the fabric to be cut.

Durch Schrägstellen des Handgriffes und dadurch verbundenes Anheben der Greiferspitze gegenüber der Auflagerlinie der Rollen b1, b2 auf den Unterlagen wird in dem zu schneidenden Stoff i zwischen den Rollen bi und b.. eine nach Wunsch veränderliche Spannung erzeugt, die wesentlich zu einem sauberen und schnellen Schnitt beiträgt. Sind dickere Stoffe, Stofflagen, dünnere Bleche oder ähnliches Material zu schneiden, so wird in manchen Fällen der Reibungsdruck zwischen den Rollen b, und b2 und der Unterlage zur Überwindung des Schneidwiderstandes nicht genügen, um eine einwandfreie Arbeit zu sichern. Für diese Fälle ist ein Kraftantrieb der Messerwelle vorzusehen, wäbrand für den Vorschub der Schere der Handantrieb bestehen bleibt.By tilting the handle and thereby lifting the hook tip against the support line of the rolls b1, b2 on the documents, a variable tension is generated in the fabric i to be cut between the rolls bi and b .., which is essential for a clean and fast Cut contributes. If thicker fabrics, layers of fabric, thinner sheet metal or similar material are to be cut, in some cases the frictional pressure between rollers b and b2 and the base is not sufficient to overcome the cutting resistance to ensure proper work. In these cases, a power drive for the knife shaft must be provided, while the manual drive remains in place to advance the scissors.

Als Kraftantrieb kann beispielsweise ein kleiner Elektromotor, pendelnd an die Zimmerdecke aufgehängt, Verwendung finden, der durch eine biegsame Welle mit der in Kugellagern gelagerten Messerwelle L (Abb. 6) verbunden ist. Die Verstellung des Greifers e, der in diesem Falle gegen Unfallgefahr mit einem Messerschutz tt versehen und dessen Greiferschneide auswechselbar angeordnet ist, erfolgt durch Ein- oder Ausschrauben des Greifergewindes o aus dem Haltergriff a durch Drehen desselben. Eine Schraube p dient zum Feststellen des Greifers. g sind Ölfilze, die die Schmierung der Führungsrollen b besorgen. r ist das Angriffsende der beweglichen Welle. Im übrigen ist die Handhabung dieselbe wie die der vorher beschriebenen Handrollenschere.A small oscillating electric motor, for example, can be used as a power drive Suspended from the ceiling, using a flexible shaft is connected to the knife shaft L (Fig. 6) mounted in ball bearings. The adjustment of the gripper e, which in this case tt with a knife guard against the risk of accidents provided and whose gripper cutting edge is arranged to be exchangeable, takes place through Screwing in or unscrewing the hook thread o from the holder handle a by turning same. A screw p is used to fix the gripper. g are oil felts that get the lubrication of the guide rollers b. r is the attack end of the movable Wave. Otherwise, the handling is the same as that of the hand roller shears described above.
