Die Erfindung betrifft einen Querschneider.The invention relates to a cross cutter.
Ein Querschneider ist aus der DE 43 21 163 A1 bekannt. Der Querschneider ist zum Schneiden von Bahnen aus flexiblen Werkstoffen vorgesehen, wobei ein um seinen Masseschwerpunkt drehbarer, zylindrischer Walzenkörper zur Anwendung gelangt, der an zumindest einer Umfangsstelle mit einem sich im wesentlichen parallel zu der Achse erstreckenden und in einer metallischen Halterung aufgenommenen, radial nach außen weisenden Messer versehen ist. Der Walzenkörper besteht aus einem Kunststoffrohr, wobei die Halterung seperat erzeugt und mit dem Kunststoffrohr verbunden ist.A cross cutter is known from DE 43 21 163 A1. The cross cutter is intended for cutting webs from flexible materials, with a cylindrical roller body rotatable around its center of gravity arrives at essentially one circumferential point with one extending parallel to the axis and in a metallic holder Recorded, radially facing knife is provided. Of the Roller body consists of a plastic tube, with the holder separate generated and connected to the plastic tube.
Der Erfindung liegt die Aufgabe zugrunde, einen Querschneider der eingangs genannten Art derart weiterzuentwickeln, daß sich eine vereinfachte Festlegung des Messerhalters am Walzenkörper ergibt und der Querschneider dadurch einen teilearmen Aufbau aufweist und in fertigungstechnischer und wirtschaftlicher Hinsicht einfach und kostengünstig herstellbar ist.The invention has for its object a cross cutter of the beginning mentioned type to develop in such a way that a simplified definition of the knife holder on the roller body and the cross cutter has a low-parts structure and in terms of manufacturing technology and economy Regarding simple and inexpensive to manufacture.
Diese Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen
von Anspruch 1 gelöst. Auf vorteilhafte Ausgestaltungen nehmen die Unteransprüche
Bezug.This object is achieved with the characterizing features
solved by
Zur Lösung der Aufgabe ist ein Querschneider vorgesehen, umfassend einen Walzenkörper und zumindest ein sich im wesentlichen parallel zur Rotationsachse des Querschneiders erstreckendes, radial nach außen weisendes Messer, das in zumindest zwei mit axialem Abstand zueinander benachbarten Messerhaltem aufgenommen ist, wobei jeder Messerhalter durch zumindest einen unmittelbar mit dem Walzenkörper verbundenen Stehbolzen am Walzenkörper festgelegt ist. Hierbei ist von Vorteil, daß eine sich in axialer Richtung erstreckende Leiste, die im wesentlichen der axialen Länge des Walzenkörpers entspricht und mit zumindest einem Messerhalter verbunden ist, nicht zur Anwendung gelangt. Bei derartigen Ausgestaltungen ist es von Nachteil, daß die Leiste und der Walzenkörper häufig aus unterschiedlichen Materialien bestehen. Der Walzenkörper besteht beispielsweise aus Kunststoff, die Leiste beispielsweise aus Stahl. Durch die voneinander abweichenden Temperaturausdehnungskoeffizienten der unterschiedlichen Werkstoffe stellt sich während der bestimmungsgemäßen Verwendung eine Verformung des Querschneiders ein; die Genauigkeit des Schnitts wird dadurch nachteilig beeinflußt. Demgegenüber sind bei dem erfindungsgemäßen Querschneider die Stehbolzen untereinander nicht verbunden. Auch dann, wenn die Stehbolzen und der Walzenkörper aus voneinander abweichenden Materialien bestehen, also voneinander abweichende Temperaturausdehnungskoeffizienten haben, bleibt die Verformung des Querschneiders in jedem Fall innerhalb einer unproblematischen, zulässigen Toleranz. Dadurch, daß die Stehbolzen unmittelbar mit dem Walzenkörper verbunden sind, ergibt sich insgesamt ein besonders teilearmer Aufbau. Die Herstellung des Querschneiders ist dadurch kostengünstig und in fertigungstechnischer Hinsicht einfach.To achieve the object, a cross cutter is provided, comprising one Roller body and at least one substantially parallel to the axis of rotation of the cross cutter, pointing radially outwards Knife that is at least two adjacent to each other with an axial distance Knife holder is included, each knife holder by at least a stud bolt directly connected to the roller body on the roller body is set. The advantage here is that one is in the axial direction extending ledge, which is essentially the axial length of the roller body corresponds and is connected to at least one knife holder, not for use reached. In such configurations, it is disadvantageous that the The bar and the roller body often consist of different materials. The roller body is made of plastic, for example, the bar for example from steel. Due to the differing coefficients of thermal expansion of the different materials arises during the intended use a deformation of the cross cutter; the accuracy of the cut is adversely affected. In contrast are the studs with each other in the cross cutter according to the invention not connected. Even if the studs and the roller body are off there are different materials, that is, different materials Have thermal expansion coefficients, the deformation remains of the cross cutter in any case within an unproblematic, permissible Tolerance. The fact that the studs directly with the roller body connected, the overall result is a particularly low-parts structure. The Manufacture of the cross cutter is therefore inexpensive and in terms of manufacturing technology Respect simply.
Die unmittelbare Verbindung der Stehbolzen mit dem Walzenkörper kann beispielsweise durch eine Presspassung gebildet sein und/ oder die Stehbolzen sind in kongruent gestaltete Ausnehmungen des Walzenkörpers eingeklebt. Auch eine Verschweißung der Stehbolzen mit dem Walzenkörper ist möglich.The direct connection of the stud bolts to the roller body can, for example be formed by a press fit and / or the stud bolts are glued into congruently shaped recesses in the roller body. The stud bolts can also be welded to the roller body.
Gemäß einer vorteilhaften Ausgestaltung ist es vorgesehen, daß der Walzenkörper aus einem mit Kohlenstoffasern verstärkten Epoxidharz besteht. Querschneider gelangen bei der Herstellung von Bogen aus einer kontinuierlich zugeführten Bahn aus einem flexiblen Werkstoff, beispielsweise Papier zur Anwendung. Von entscheidender Wichtigkeit ist, daß die Umlaufgeschwindigkeit des Querschneiders mit der Zuführgeschwindigkeit der abzutrennenden Bahn in Übereinstimmung gebracht wird. Es ist von Vorteil, wenn der Querschneider insgesamt nur eine vergleichsweise geringe Massenträgheit aufweist, so daß er ohne nennenswerten Energieaufwand exakt an die Zuführgeschwindigkeit der abzuteilenden Bahn anpaßbar ist. Besteht der Walzenkörper aus einem mit Kohlenstoffasern verstärkten Epoxidharz, ist seine Trägheitsmasse hierdurch stark reduziert, was es wesentlich vereinfacht, die Umlaufgeschwindigkeit des Walzenkörpers an vorgegebene Zuführgeschwindigkeiten anzupassen. Außerdem ergibt sich ein weiterer Vorteil, der darin zu sehen ist, daß sehr geringe Antriebsleistungen für die Erzeugung einer Drehbewegung des Walzenkörpers genügen. Durch die Kohlenstoffasern lassen sich hochfeste Walzenkörper herstellen, die besonders dünnwandig ausgebildet sind und eine ausgezeichnete mechanische und dynamische Beständigkeit aufweisen.According to an advantageous embodiment, it is provided that the roller body consists of an epoxy resin reinforced with carbon fibers. Cross cutter arrive in the production of sheets from a continuously fed Web made of a flexible material, for example paper for use. Crucial is that the orbital speed of the cross cutter at the feed speed of the web to be cut is brought into line. It is beneficial if the cross cutter overall has only a comparatively low inertia, so that it exactly to the feeding speed of the dividable web is adaptable. If the roller body consists of a Carbon fiber reinforced epoxy resin, is its inertia greatly reduced, which greatly simplifies the orbital speed of the Adapt roller body to specified feed speeds. Furthermore there is another advantage that can be seen in the fact that very little Driving powers for the generation of a rotary movement of the roller body are enough. The carbon fibers can be used to produce high-strength roller bodies which are particularly thin-walled and excellent have mechanical and dynamic resistance.
Die Kohlenstoffasern können beispielsweise schraubengangförmig verteilt angeordnet sein, wobei die Kohlenstoffasern einander überkreuzen. Neben einer guten Biege- und Verdrehfestigkeit wird hierdurch eine gute Dämpfung von Eigenschwingungen erreicht, was die Erzielung eines sauberen Schnittbilds über eine lange Gebrauchsdauer begünstigt.The carbon fibers can, for example, be distributed in a helical fashion be, with the carbon fibers crossing each other. In addition to one good flexural and torsional strength is a good damping of natural vibrations achieved what about achieving a clean layover favors a long service life.
Bevorzugt sind die Stehbolzen in den Walzenkörper unmittelbar einlaminiert. Sekundärer Befestigungshilfsmittel bedarf es daher nicht. Durch das Einlaminieren der Stehbolzen in den Walzenkörper ergibt sich eine unlösbare, dauerhaltbare Verbindung.The studs are preferably laminated directly into the roller body. There is therefore no need for secondary fastening aids. By laminating the stud in the roller body results in an unsolvable, durable Connection.
Die Stehbolzen können jeweils ein Außengewinde aufweisen, wobei die Messerhalter durch jeweils zumindest eine Mutter mit dem Stehbolzen verbunden sind. Die Montage eines derartigen Querschneiders ist besonders einfach. Auf die in den Walzenkörper einlaminierten Stehbolzen wird jeweils ein Messerhalter aufgesetzt, wobei die Messerhalter und das Messer beispielsweise eine vormontierbare Einheit bilden können, so daß die Einheit insgesamt auf die Stehbolzen aufgefädelt wird. Nach einer anderen Ausgestaltung besteht die Möglichkeit, daß zunächst die Messerhalter auf die jeweiligen Stehbolzen montiert werden, daß anschließend das Messer in die aufgefädelten Messerhalter eingesetzt wird und daß im Anschluß daran die Messerhalter mit den Muttern auf den Stehbolzen befestigt werden.The stud bolts can each have an external thread, the knife holder connected to the stud by at least one nut each are. The assembly of such a cross cutter is particularly simple. On the stud bolts laminated into the roller body each become a knife holder put on, the knife holder and the knife, for example, a can form pre-assembled unit, so that the unit as a whole on the Stud bolt is threaded. According to another embodiment, the Possibility that the knife holder is first mounted on the respective stud bolts be that the knife in the threaded knife holder is used and that afterwards the knife holder with the nuts be attached to the stud bolts.
Gemäß einer vorteilhaften Ausgestaltung ist es vorgesehen, daß der Walzenkörper rohrförmig ausgebildet ist. Durch die rohrförmige Ausgestaltung wird die Erzielung einer geringen Trägheitsmasse weiter begünstigt. Im Hinblick auf einen möglichst exakten Rundlauf ist der Walzenkörper bevorzugt hohlzylinderförmig ausgebildet. Bei Bedarf besteht die Möglichkeit, nur ein einziges Messer am Außenumfang des Walzenkörpers anzubringen, wobei der Trägheitsmassenschwerpunkt in die Rotationsachse gelegt wird, so daß sich ein Abstand von der Achse des Kunststoffrohrs ergibt. Unwuchterscheinungen bei Einleitung einer Drehbewegung können auch bei solchen Ausführungen nicht auftreten. Großformatige Bögen können aus einer flexiblen Bahn herausgetrennt werden, ohne daß es der Verwendung eines Walzenkörpers von sehr großem Durchmesser bedarf.According to an advantageous embodiment, it is provided that the roller body is tubular. Due to the tubular design Achievement of a low inertial mass further favored. With regard to one The most exact concentricity, the roller body is preferably hollow cylindrical educated. If necessary, there is the option of only a single knife to attach to the outer circumference of the roller body, the center of inertia is placed in the axis of rotation so that there is a distance from the axis of the plastic tube. Imbalance phenomena at initiation a rotary movement cannot occur even in such designs. Large-sized sheets can be separated from a flexible sheet be without the use of a roller body of very large Diameter required.
Die Wandung des Walzenkörpers kann von den Stehbolzen in radialer Richtung vollständig durchdrungen sein. Hierbei ist von Vorteil, daß die Führung der Stehbolzen in der entsprechenden Ausnehmung des Walzenkörpers besonders lang und somit auch besonders genau ist. Beim Einlaminieren der Stehbolzen in den Walzenkörper wird durch die zuvor beschriebene Ausgestaltung eine große Fläche für die Bindung der beiden Teile aneinander sichergestellt.The wall of the roller body can move from the stud bolts in the radial direction to be completely permeated. The advantage here is that the leadership of Studs especially in the corresponding recess of the roller body long and therefore particularly precise. When laminating the stud bolts is in the roller body by the previously described configuration large area for the binding of the two parts to one another is ensured.
Der Walzenkörper und die Stehbolzen können materialeinheitlich ausgebildet sein. Hierbei ist von Vorteil, daß die Materialien von Walzenkörper und Stehbolzen übereinstimmende Temperaturausdehnungskoeffizienten aufweisen und unterschiedliche Wärmedehnungen während der bestimmungsgemäßen Verwendung des Querschneiders sicher ausgeschlossen sind. Unerwünschte Spannungen zwischen den Teilen werden dadurch vermieden, was im Hinblick auf eine sichere Festlegung der Stehbolzen im Walzenkörper von hervorzuhebendem Vorteil ist.The roller body and the stud bolts can be made of the same material be. The advantage here is that the materials of the roller body and stud bolts have matching thermal expansion coefficients and different thermal expansions during the intended use of the cross cutter are safely excluded. Undesirable Tensions between the parts are avoided, which in view on a secure fixing of the studs in the roller body Advantage is.
