Description
Die Erfindung betrifft eine Schneidvorrichtung mit einer Schneidwalze, die an ihrem Umfang angeordnete Bohrungen zur Aufnahme von durch Eindrehen von Schrauben wirkenden Spannmitteln aufweist, mit denen mindestens ein Stanz- oder Schneidmesser lösbar befestigbar ist.The invention relates to a cutting device with a cutting roller which is arranged on its circumference Has bores for receiving clamping means acting by screwing in screws with which at least one punching or cutting knife can be releasably attached.
Eine derartige Schneidvorrichtung ist beispielsweise aus der DE-AS 10 66 860 bekannt. Am Umfang der Schneidwalze dieser Schneidvorrichtung ist eine leicht schraubenlinienförmig verlaufende Längsnut angeordnet, in der das Stanz- oder Schneidmesser mit seinem Rücken liegt. Die Bohrungen grenzen an eine oder beide Seiten der Längsnut an und gehen unmittelbar in diese über. In den Bohrungen befinden sich keilartige Spannmittel, die mit Hilfe von Schrauben festgezogen werden. Die Achsen der Schrauben stehen winklig zur Mittelebeine des zu befestigenden Stanz- oder Schneidmessers, was zur Folge hat, daß die keilförmigen Spannmittel beim Anziehen der Schrauben das Stanzoder Schneidmesser je nach Ausführungsform entweder fest gegen die eine Begrenzungswand der Längsnut drücken oder zwischen sich festklemmen.Such a cutting device is known from DE-AS 10 66 860, for example. At the scope of the The cutting roller of this cutting device has a slightly helical longitudinal groove, in which the punching or cutting knife lies with its back. The holes are adjacent to one or both Sides of the longitudinal groove and go directly into this. There are wedge-like holes in the holes Clamping devices that are tightened with the help of screws. The axes of the screws are at an angle Center legs of the punching or cutting knife to be attached, with the result that the wedge-shaped Clamping means when tightening the screws either the punching or cutting knife, depending on the embodiment Press firmly against one wall of the longitudinal groove or clamp it between them.
An einer Schneidwalze gemäß der DE-AS 10 66 860 können Stanz- und Schneidmesser zwar schraubenlinienförmig befestigt werden, doch ist dafür zunächst erforderlich, daß am Umfang der Schneidwalze ein; entsprechend schraubenlinienförmig verlaufende Nut vorgesehen ist. Das Einbringen dieser Nut in die Schneidrolle ist naturgemäß mit herstellungstechnischen Schwierigkeiten verbunden, die einen erheblichen Aufwand bedingen. Das Gleiche gilt für die in die Messernut oder Längsnut übergehenden Ausnehmungen, die beim Gegensstand der DT-AS 10 66 860 zur Aufnahme der keilförmigen Spannmittel dienen.On a cutting roller according to DE-AS 10 66 860, punching and cutting knives can be helical be attached, but it is first necessary that on the circumference of the cutting roller a; a corresponding helical groove is provided. The introduction of this groove in the Cutting roller is naturally associated with manufacturing difficulties, which are considerable Require effort. The same applies to the recesses that merge into the knife groove or longitudinal groove, which, in the case of the DT-AS 10 66 860, are used to accommodate the wedge-shaped clamping devices.
Eine Veränderung der Lage des Stanz- oder Schneidmessers auf der Schneidwalze ist nach der Lehre der DE-AS 10 66 860 nicht möglich, weil die Messerbzw. Längsnut vorgegeben ist und eine Veränderung der Lage des Messers nicht zuläßt.A change in the position of the punching or cutting knife on the cutting roller is according to the teaching the DE-AS 10 66 860 not possible because the knife or. Longitudinal groove is given and a change the position of the knife does not allow.
Durch die DE-PS 2 70 872 ist ferner eine Querschneidemaschine für Stoffbahnen bekanntgeworden, deren umlaufendes Spiralmesser sich unmittelbar von der Oberfläche der Schneidwalze weg erstreckt. Die Art der Befestigung dieses Spiralmessers geht aus der DT-PS 2 70 872 nicht hervor.From DE-PS 2 70 872 a cross cutting machine for webs of fabric is also known whose orbiting spiral knife extends directly from the surface of the cutting roller away. The kind of The DT-PS 2 70 872 does not reveal the attachment of this spiral knife.
Aus dem DE-GM 19 83 394 ist schließlich eine Befestigung für Stanzmesser od. dgl. bekannt, gemäß der das Messer zwischen zwei Messerbacken mit Hilfe von Schrauben festgeklemmt ist. Verwendet wird ein derartiger Messerbalken im Zusammenhang mit Messerwalzen, beispielsweise in Vorrichtungen zum Abtrennen von Papierbahnen. Eine schraubenlinienförmige Einstellung des Messers bzw. eine Veränderung einer Winkellage zur Laufrichtung der Papierbahn ist nicht möglich.Finally, from DE-GM 19 83 394 a fastening for punching knives or the like is known, according to which the knife is clamped between two knife jaws with the help of screws. A such knife bars in connection with knife rollers, for example in devices for severing of paper webs. A helical setting of the knife or a change in one Angular position to the running direction of the paper web is not possible.
Der Erfindung liegt die Aufgabe zu Grunde, eine Schneidwalze mit mindestens einem über ihren Umfang vorstehenden Stanz- oder Schneidmesser zu schaffen, die es erlaubt, das Stanz- oder Schneidmesser unter verschiedenen Winkeln, also mit unterschiedlicher Steigung am Umfang zu befestigen.The invention is based on the object of providing a cutting roller with at least one over its circumference to create protruding punching or cutting knife that allows the punching or cutting knife under different angles, so to be attached to the circumference with different inclines.
Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß die Spannmittel aus Halteklötzen bestehen, die aus der Manteloberfläche der Schneidwalze ragen, und an denen das Stanz- oder Schneidmesser mit seinem Rücken auf dem Umfang der Schneidwalze liegend anschraubbar ist.To solve this problem, the invention provides that the clamping means consist of retaining blocks, which from the jacket surface of the cutting roller protrude, and where the punching or cutting knife with his Back can be screwed lying on the circumference of the cutting roller.
Ein derart an der Schneidwalze befestigtes Messer kann bei Vorhandensein mehrerer Ersatzbohrungen ohne Mühe auf verschiedene Winkelstellungen zur Drehachse des Messers gebracht werden. Somit ist es möglich, die Schneidvorrichtung durch Änderung der Winkelstellung auf die Materialeigenschaften des Stanzgutes einzustellen, so daß die SchneidvorrichtungA knife attached to the cutting roller in this way can be used if several replacement bores are present can be easily brought to different angular positions to the axis of rotation of the knife. So it is possible, the cutting device by changing the angular position on the material properties of the Set the material to be cut so that the cutting device
immer mit dem geringstmöglichen Stanzdruck betrieben werden kann.can always be operated with the lowest possible punching pressure.
Die zur Befestigung der Stanz- oder Schneidmesser dienenden Halteklötze sind derart ausgestaltet, daß das Stanz- oder Schneidmesser mit seinem Hucken immer auf dem Umfang der Schneidwalze aufliegt. Dies ist günstig für die Übertragung der auftretenden Stanz- und Schneidkräfte auf die Schneidrolle.The holding blocks used for fastening the punching or cutting knife are designed in such a way that the Punching or cutting knife always rests with its crook on the circumference of the cutting roller. This is favorable for the transfer of punching and cutting forces to the cutting roller.
Besondere Ausgestaltungen und Weiterbildungen der Erfindung gehen aus der Beschreibung und den Unteransprüchen im Zusammenhang mit der Zeichnung hervor.Special refinements and developments of the invention emerge from the description and the Subclaims in connection with the drawing emerge.
