Die vorliegende Erfindung betrifft eine Vorrichtung zur Längstrennung eines insbesondere aus Papierlagen oder Pappe hergestellten Rohres, umfassend eine in einer Trennebene angeordnete Stützeinrichtung zur Anordnung innerhalb des Rohres und eine in der Trennebene angeordnete Schneideinrichtung zur Anordnung außerhalb des Rohres, wobei dieThe present invention relates to a device for the longitudinal separation of a particular made of paper sheets or cardboard tube, comprising a arranged in a parting plane support means for arrangement within the tube and arranged in the parting plane cutting device for arrangement outside the tube, wherein the
Stützeinrichtung und die Schneideinrichtung in der Trennebene einander gegenüberliegend angeordnet sind und eine erste Trennanordnung zur Durchtrennung eines Rohrwandabschnitts ausbilden, wobei die Schneid- einrichtung ein auf einer angetriebenen Schneidwelle angeordnetes Kreismesser und die Stützeinrichtung eine auf einer Stützachse angeord- nete Stützrolle aufweist und die Schneidrolle und die Stützachse in einem Achsabstand a voneinander angeordnet sind, derart, dass zwischen einer Schneidkante des Kreismessers und einer Stützfläche der Stützrolle in der Trennebene ein Schneidspalt definiert ist. Aus der DE 10 2013 213 607 Al ist es bekannt, ausgehend von einem als Rechteckrohr ausgebildetem Kartonrohr als Halbzeug durch Längstren nung zweier einander gegenüberliegender Rohrwandabschnitte des Kartonrohrs U-förmige Kartonprofile herzustellen, die durch mehrfaches Abkanten in komplexe Kartonprofile umgewandelt werden können, wel- che zur Herstellung einer aus Karton gebildeten Transportpalette dienen. Supporting device and the cutting device in the parting plane are arranged opposite to each other and form a first separation assembly for cutting a pipe wall portion, wherein the cutting device has a arranged on a driven cutting shaft circular blade and the support means on a support axis angeord- Neten support role and the cutting roller and the Support axis are arranged at an axial distance a from each other, such that between a cutting edge of the circular blade and a support surface of the support roller in the parting plane a cutting gap is defined. From DE 10 2013 213 607 Al it is known, starting from a rectangular tube designed as a cardboard tube as a semi-finished product by Längstren tion of two opposing pipe wall sections of Cardboard tube To produce U-shaped carton profiles, which can be converted by multiple folding into complex carton profiles, which are used to produce a transport pallet formed from cardboard.
Aus dem Vorstehenden ergibt sich, dass insbesondere für eine Großseri- enherstellung derartiger Paletten in entsprechender Anzahl U-förmige Kartonprofile zur Verfügung gestellt werden müssen, so dass es unter wirtschaftlichen Gesichtspunkten darauf ankommt, die zur Herstellung der U-förmigen Profile notwendigen Trennvorgänge an rechteckförmigen Kartonrohren möglichst effektiv durchführen zu können. Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eineIt follows from the above that, in particular for large-scale production of such pallets, a corresponding number of U-shaped cardboard profiles must be made available, so that from an economic point of view it is important to have the separation processes on rectangular cardboard tubes necessary for the production of the U-shaped profiles to be able to carry out as effectively as possible. The present invention is therefore based on the object, a
Vorrichtung zur Längstrennung eins Kartonrohres vorzuschlagen, die die Durchführung der Längstrennung besonders effektiv ermöglicht. Device for longitudinal separation of a cardboard tube to propose that allows the implementation of the longitudinal separation particularly effective.
Zur Lösung dieser Aufgabe weist die erfindungsgemäße Vorrichtung die Merkmale des Anspruchs 1 auf. Die erfindungsgemäße Vorrichtung umfasst eine in einer Trennebene angeordnete Stützeinrichtung zur Anordnung innerhalb des Rohres und eine in der Trennebene angeordnete Schneideinrichtung zur Anordnung außerhalb des Rohres, wobei die Stützeinrichtung und die Schneidein richtung in der Trennebene einander gegenüberliegend angeordnet sind und eine erste Trennanordnung zur Durchtrennung eines Rohrwandab- schnitts ausbilden, wobei die Schneideinrichtung ein auf einer angetrie- benen Schneidwelle angeordnetes Kreismesser und die Stützeinrichtung eine auf einer Stützachse angeordnete Stützrolle aufweist, wobei die Schneidwelle und die Stützachse in einem Achsabstand voneinander angeordnet sind, derart, dass zwischen einer Schneidkante des Kreismes- sers und einer Stützfläche der Stützrolle in der Trennebene ein Schneid- spalt definiert ist. To solve this problem, the device according to the invention has the features of claim 1. The inventive device comprises a arranged in a parting plane support means for arrangement within the tube and arranged in the parting plane cutting device for arrangement outside the tube, wherein the support means and the Schneidein direction in the parting plane are arranged opposite to each other and a first separation arrangement for the transection of a Rohrwandab - Form cut, wherein the cutter has a arranged on a driven cutting shaft circular blade and the support means comprises a support shaft disposed on a support roller, wherein the cutting shaft and the support shaft are arranged at an axial distance from each other, such that between a cutting edge of the circular ses and a support surface of the support roller in the parting plane is defined a cutting gap.
Die erfindungsgemäße Vorrichtung ermöglicht aufgrund der innerhalb des Rohres angeordneten Stützeinrichtung, die mit der außerhalb des Rohres angeordneten Schneideinrichtung zusammenwirkt, die Ausbil- dung einer Vorrichtung zur Längstrennung, die nicht nur die eigentliche Längstrennung eines Rohrwandabschnitts ermöglicht, sondern die dabei auch gleichzeitig das zu durchtrennende Rohr aufnimmt, wobei aufgrund der Anordnung der Stützeinrichtung innerhalb des Rohres eine Relativbe- wegung des Rohres gegenüber der Trennanordnung in Längsrichtung des Rohres ermöglicht wird. The inventive device allows due to the arranged inside the tube support means, with the outside of the Pipe arranged cutting device, the training of a device for longitudinal separation, which not only allows the actual longitudinal separation of a pipe wall portion, but also simultaneously receives the pipe to be cut, due to the arrangement of the support means within the tube relative movement of the pipe relative to the separating arrangement in the longitudinal direction of the tube is made possible.
Damit ist es möglich, die Vorrichtung zur Längstrennung unmittelbar angrenzend an eine Transportvorrichtung zur kontinuierlichen Förderung von Rohren anzuordnen und das Rohr nach Herstellung, die üblicherwei- se in einem Wickelvorgang erfolgt, bei dem das auf einem Wickeldorn angeordnete Rohr durch Umwickeln des rotierenden Wickeldorns mit Papierlagen hergestellt wird, in Längsrichtung des Rohres über die Stützeinrichtung zu bewegen um so die Längstrennung in zumindest einem Rohrwandabschnitt durchzuführen. This makes it possible to arrange the device for longitudinal separation immediately adjacent to a transport device for the continuous delivery of pipes and the pipe after production, which usually takes place in a winding process in which the pipe arranged on a winding mandrel is wound by wrapping the rotating winding mandrel with paper layers is made to move in the longitudinal direction of the tube on the support means so as to perform the longitudinal separation in at least one tube wall portion.
Die Längstrennung in einem zweiten, dem ersten Rohrwandabschnitt gegenüberliegenden Rohrwandabschnitt, um aus einem Rechteckrohr zwei U-förmige Kartonprofile herzustellen, kann in einfacher Weise dadurch herstellt werden, dass in Längsrichtung des Rohres der ersten Trennanordnung eine zweite Trennanordnung in einem der Rohrlänge entsprechenden Abstand nachgeordnet wird, um unmittelbar nach Durch führung der Durchtrennung des ersten Rohrwandabschnitts auch die Durchtrennung des zweiten, dem ersten Rohrwandabschnitt gegenüberlie- genden Rohrwandabschnitts durchführen zu können. The longitudinal separation in a second tube wall section opposite the first tube wall section in order to produce two U-shaped cardboard profiles from a rectangular tube can be produced in a simple manner by subordinating a second separating arrangement in the longitudinal direction of the tube of the first separating arrangement to a distance corresponding to the tube length in order to be able to carry out the severing of the second pipe wall section lying opposite the first pipe wall section immediately after the passage through the first pipe wall section.
Bei einer bevorzugten Ausführungsform der Vorrichtung ist zur Einstel- lung des Schneidspaltes der Abstand zwischen der Schneidkante des Kreismessers und der Stützfläche der Stützrolle kleiner gewählt als die Wandstärke eines zu durchtrennenden Rohrwandabschnitts, so dass in jedem Fall ein Kontakt zwischen der Schneidkante und der Stützfläche bei der Durchführung des Trennvorgangs unterbleibt und so im Wesentli- chen keine Abnutzung der Schneidkante während der Durchführung eines Trennvorgangs erfolgt. In a preferred embodiment of the device for adjusting the cutting gap, the distance between the cutting edge of the circular blade and the support surface of the support roller chosen smaller than the wall thickness of a pipe wall section to be cut, so that in each case a contact between the cutting edge and the support surface in the Carrying out the separation process and thus essentially There is no wear on the cutting edge during a separation process.
Darüber hinaus kann somit die auf die Schneidwelle übertragene An triebsleistung zu einem wesentlichen Teil zur Unterstützung des Vor- triebs des Rohres während der Durchführung des Trennvorgangs genutzt werden. Infolge der Beabstandung der Schneidkante von der Stützfläche erfolgt die Durchtrennung des Rohrwandabschnitts im Wesentlichen durch eine Quetschung des Rohrwandabschnitts in der Trennebene, so dass die Wandstärke des Rohrwandabschnitts in der Trennebene auf ein Minimum reduziert wird und der Rohrwandabschnitt in der Trennebene aufreißt. Dieses Aufreißen kann gegebenenfalls noch durch eine mit der Stützeinrichtung kombinierten Spreizeinrichtung unterstütz werden, die, ebenfalls wie die Stützeinrichtung, innerhalb des Rohres angeordnet ist und in einer zur Trennebene senkrechten Spreizebene von innen gegen einander gegenüberliegende Rohrwandabschnitte drückt. In addition, thus, the drive power transmitted to the cutting shaft can be largely utilized to assist in advancing the tube while performing the separation operation. As a result of the spacing of the cutting edge from the support surface, the transection of the tube wall portion is essentially done by crushing the tube wall portion in the parting plane so that the wall thickness of the tube wall portion in the parting plane is minimized and the tube wall portion ruptures in the parting plane. If necessary, this tearing can also be assisted by a spreading device combined with the supporting device, which, like the supporting device, is arranged inside the tube and presses against tube wall sections lying opposite one another from the inside in a spreading plane perpendicular to the dividing plane.
Vorzugsweise weist die Schneidkante des Kreismessers ein Schneidkan tenprofil auf mit zwei unter einem Schneidenwinkel V-förmig zueinander angeordneten Schneidflanken auf, die zur Ausbildung der Schneidkante über eine Kantenrundung miteinander verbunden sind, die einen Kanten- radius aufweist, der kleiner gleich 0,5 mm ist, so dass die Ausbildung einer„stumpfen“ Schneidkante ermöglicht wird, die einer möglichst geringen Abnutzung der Schneidkante unterliegt. The cutting edge of the circular blade preferably has a cutting edge profile with two cutting flanks which are arranged at V-shaped mutually at a cutting angle and which are connected to form the cutting edge via an edge rounding which has an edge radius which is less than or equal to 0.5 mm , so that the formation of a "blunt" cutting edge is made possible, which is subject to the least possible wear of the cutting edge.
Wenn in der Trennebene gegenüberliegend der ersten Trennanordnung eine zweite Trennanordnung vorgesehen ist, die zur Durchtrennung eines dem ersten Rohrwandabschnitt gegenüberliegenden zweiten Rohrwandab schnitts dient, kann eine gleichzeitige Durchtrennung der einander gegenüberliegenden Rohrwandabschnitte erfolgen. If a second separating arrangement is provided in the parting plane opposite the first separating arrangement, which serves for the transection of a second pipe wall section opposite the first pipe wall section, a simultaneous severing of the opposing pipe wall sections can take place.
Vorzugsweise sind die Stützeinrichtung der zweiten Trennanordnung und die Stützeinrichtung der ersten Trennanordnung so angeordnet, dass sie sich gegeneinander abstützen, so dass eine besonders kompakte Ausge- staltung der innerhalb des Rohres angeordneten Komponenten der Trenn anordnungen möglich ist. Preferably, the support means of the second separation arrangement and the support means of the first separation arrangement are arranged so that they bear against each other, so that a particularly compact Ausge- staltung of the arranged within the tube components of the separation arrangements is possible.
Wenn darüber hinaus die Stützrolle der zweiten Trennanordnung sich an der Stützrolle der ersten Trennanordnung abstützt, derart, dass die Stützrollen bei einem Trennvorgang aufeinander abrollen, ist eine unmit telbar benachbarte Anordnung der Stützeinrichtungen möglich, wobei zur gegenseitigen Abstützung keine weiteren Einrichtungen benötigt werden. In addition, when the support roller of the second separation assembly is supported on the support roller of the first separation arrangement, such that the support rollers roll on each other in a separation process, a immedi applicable adjacent arrangement of the support means is possible, with no additional facilities needed for mutual support.
Wenn die Stützrollen der Stützeinrichtungen eine in der Ebene der Stützachsen übereinstimmende Stützflächenkontur aufweisen und ein Durchmesser aufweisen, derart, dass der zweifache Durchmesser dem Abstand zweier in der Trennebene einander gegenüberliegender Rohr wandabschnitte entspricht, ist eine optimale Anpassung der Stützeinrich tungen an einen jeweiligen Rohrquerschnitt möglich. If the support rollers of the support means have a matching in the plane of the support axes support surface contour and have a diameter such that twice the diameter corresponds to the distance between two in the parting plane opposite pipe wall sections, an optimal adjustment of Stützeinrich obligations to a respective pipe cross-section is possible.
Zur Längstrennung eines einen runden Rohrquerschnitt aufweisenden Rohres ist es besonders vorteilhaft, wenn die Stützrollen als ballige Rollen ausgebildet sind. For the longitudinal separation of a tube having a round tube cross-section, it is particularly advantageous if the support rollers are formed as crowned rollers.
Zur Längstrennung eines Rechteckrohres ist es besonders vorteilhaft, wenn die Stützrollen als Zylinderrollen ausgebildet sind. For the longitudinal separation of a rectangular tube, it is particularly advantageous if the support rollers are designed as cylindrical rollers.
Nachfolgend wird eine bevorzugte Ausführungsform der Erfindung anhand der Zeichnung näher erläutert. Hereinafter, a preferred embodiment of the invention will be explained in more detail with reference to the drawing.

Support axes 25 of the support means 19, 20 with an end cross-section 34 of the mandrel 35 in a manner not shown here, for example, via boom, are connected to the cutting shafts 23 of the cutting devices 19, 20 in a common to the support axes 25 to the end cross-section 34 of the mandrel 35 parallel plane. Thus, the tubular tube 12 axially advanced on the mandrel 35 can be withdrawn from the mandrel 35 in the longitudinal direction of the rectangular tube 12, such that the opposing Rohrwandabschnit th 13, 14 each by the cutting edges 27 of the circular blade 24 and the treads 33rd the support rollers 26 formed cutting gap 29 are pulled and the formation of the separating cuts 15 and 16 in the parting plane T (Fig. 1) takes place.
Aufgrund der über eine hier nicht näher dargestellte Antriebseinrichtung angetriebenen Schneidwellen 23 kann durch den zwischen den Schneid- kanten 27 und den Rohrwandabschnitten 13 , 14 beim Trennvorgang erfolgenden Eingriff das vorgenannte Abziehen des Rechteckrohres 12 vom Dorn 35 unterstützt werden. Hierzu kann insbesondere eine Profilie- rung der Schneidkanten 27 vorgesehen sein. As a result of the cutting shafts 23 driven by a drive device, not shown here, the abovementioned pulling off of the rectangular tube 12 can take place by the engagement between the cutting edges 27 and the tube wall sections 13, 14 during the separation process supported by the thorn 35. For this purpose, in particular a profiling of the cutting edges 27 may be provided.
