Die Schneidmesser 20, 21 sind vorteilhafterweise um 180° zueinander versetzt angeordnet, so daß während des Schneidvorganges auf das Rohr 11 eine gleichmäßige Verteilung der Schnittkräfte gegeben ist. Die Schneidmesser 20, 21 werden entlang der Achse 23 solange zugestellt, bis sie auf einer Stirnfläche 24 eines Ambosses 26 anliegen. Der Schnitt ist dann vollendet bzw. die Zustellung der Schneidmesser 20, 21 wird dann gestoppt, wenn das freie Ende des Rohres 11 von dem in Rotation versetzten Rohrabschnitt wegfällt.In Fig. 1 are the essential parts of a device 10 for cutting of tubes 11, such as cardboard tubes or plastic tubes, shown. Such machines can make cardboard tubes with a diameter in the decimeter range and lower meter range, preferably in a range between 25 to 340 mm, and with a wall thickness of, for example, up to 20 mm to a predetermined one Length can be cut off. The tubes 11 are on a feed device Counterholder 13 supplied, which is then run over until the one to be cut Length of the tube 11 is reached at the interface. The support rollers 16, 17 support this Tube 11 during the cutting process, in which the tube 11 via drive means in Rotation is offset. A right and left cutting tool is used during the cutting process 20, 21, which is designed as a disk-shaped cutting knife, to the longitudinal central axis of the tube 11 moves so that the cutting edges 22 of the cutting tools 20, 21 enter with the rotating tube 11 at an interface 14 and that Separate material. The cutting knives 20, 21 are advantageously at 180 ° to each other staggered so that during the cutting process on the tube 11 a uniform distribution of the cutting forces is given. The cutting knives 20, 21 are fed along the axis 23 until it is on an end face 24 of an anvil 26 concerns. The cut is then completed or the delivery of the Cutting knife 20, 21 will then stopped when the free end of the pipe 11 from the rotated pipe section falls away.

Der Amboß 26 kann durch beispielsweise einen in der Führung 28 angeordneten Anschlag in seiner radialen Bewegung nach außen begrenzbar sein. Alternativ kann vorgesehen sein, daß der Gegenhalter 13 in der Mantelfläche eine Ausnehmung aufweist, die in ihrer Größe derart ausgebildet ist, daß nur ein Teil der Stirnfläche 24 in der Mantelfläche des Gegenhalters 13 zum Anliegen kommt. Zur einfachen Herstellung und Montage ist vorgesehen, daß nach dem Einsetzen des Ambosses 26 und dem Federelement 27 eine Abdeckplatte 31 seitlich an dem Gegenhalter 13 anschraubbar ist.

The travel of the anvil 26 can up to 5 mm, with a resilient range of, for example, 1 mm in general enough.

Während des Schneidvorganges sind die Schneidwerkzeuge 20, 21 in einer ruhenden Position, so daß bei mehrmaligem Abschneiden eines Rohres 11 immer derselbe Abschnitt der Schneidkante 22 in Eingriff kommt. Um die vollständig umlaufende Schneidkante 22 einsetzen zu können, werden die Schneidmesser 20, 21 nach einer vorbestimmten Anzahl von Schneidvorgängen um einen gewissen Winkelbetrag verdreht, so daß eine neue und unbenutzte Schneidkante 22 zum Einsatz kommen kann. Eine derartige Indexierung kann manuell oder automatisch erfolgen. Die Indexierung kann nach jedem Schnitt, in Intervallen oder nach Bedarf erfolgen.During the cutting process, the cutting tools 20, 21 are at rest Position so that when cutting a tube 11 several times always the same Section of the cutting edge 22 comes into engagement. To the completely circulating To be able to use the cutting edge 22, the cutting knives 20, 21 according to a predetermined number of cutting operations rotated by a certain angle, so that a new and unused cutting edge 22 can be used. Such indexing can be done manually or automatically. The indexing can be done after each cut, at intervals or as required.

Weitere alternative Beschichtungen können ebenfalls vorgesehen sein.The cutting tool 20, 21 is advantageously made of HSS, hard metal or a other material suitable as a cutting tool. The cutting edge 22 can have a coating to increase the service life, for example a polycrystalline diamond coating or a cubic bomitrite coating. Other alternative coatings can also be provided.

Alternativ kann eine kinematische Umkehr für das Ablängen des Rohres 11 vorgesehen sein, wobei die Schneidmesser 20, 21 um das Rohr 11 rotieren und auf deren Lagerachse ruhend angeordnet sind. Dabei wird gleichzeitig der Amboß 26 rotierend angetrieben. Der Amboß 26 und das Schneidmesser 20, 21 sind, in bewegtem System gesehen, ruhend zueinander angeordnet.Alternatively, a kinematic reversal can be provided for cutting the tube 11 to length be, the cutting knives 20, 21 rotating around the tube 11 and on their bearing axis are dormant. At the same time the anvil 26 is driven in rotation. The anvil 26 and the cutting knife 20, 21 are in a moving system seen, arranged resting to each other.

Alternativ kann auch vorgesehen sein, daß das Rohr 11 stehend angeordnet ist und die Schneidmesser 20, 21 rotierend angetrieben werden, um ein Rohrstück abzuschneiden.Alternatively, it can also be provided that the tube 11 is arranged upright and the cutting knives 20, 21 are driven to rotate around a piece of pipe to cut off.

Alternativ kann ebenso vorgesehen sein, daß nur ein oder auch mehrere Schneidmesser über den Umfang verteilt zum Rohr 11 angeordnet sind, wobei in Abhängigkeit der Anzahl der Schneidmesser 20, 21 jeweils ein Amboß 26 im Gegenhalter 13 vorzusehen ist.Alternatively, it can also be provided that only one or more cutting knives distributed over the circumference to the tube 11, depending on the number of cutting knives 20, 21 to provide an anvil 26 in the counter holder 13 is.

Diese Ambosse 26 werden über ein Stellglied 32, das als Kulisse oder Kurvensteuerung aktiv im Verhältnis der Schnittiefe die Schneidmesser 20, 21 bewegt, so daß die Ambosse 26 gegen Ende des Schnittvorganges eine definierte radiale Bewegung nach innen durchführen, damit das Schneidmesser 20, 21 gerade noch eine letzte Lage der Papprohre schneidet, jedoch nicht mit hoher Kraft auf der Stirnfläche 24 des Ambosses 26 zum Anliegen kommt. Die aktive Bewegung der Ambosse 26 ist durch eine Kurvensteuerung gegeben, wobei die Ambosse 26 in der jeweiligen Führung 28 Federelemente aufweisen, die diese zwangsweise radial nach innen bewegen. Dadurch kann durch eine Drehbewegung des Stellgliedes 32 ein zwangsweises Nachaußenlenken gegeben sein. Die Ansteuerung der Kulisse 32 kann über eine Welle erfolgen, die in Verbindung mit einem Zustellmechanismus der Schneidmesser 20, 21 während des Schneidvorganges stehen.2 shows an alternative embodiment of two in a counter holder 13 guided anvils 26 shown. These anvils 26 are actuated by an actuator 32, that as a backdrop or curve control, the cutting knives are active in relation to the depth of cut 20, 21 moves so that the anvils 26 towards the end of the cutting process Carry out defined radial movement inwards so that the cutting knife 20, 21 barely cuts a last layer of cardboard tubes, but not with great force the end face 24 of the anvil 26 comes to rest. The active movement of the Anvils 26 are given by a curve control, the anvils 26 in the respective Guide 28 have spring elements, which these are forced radially inwards move. As a result, a rotary movement of the actuator 32 can cause a forced steering to the outside is given. The control of the backdrop 32 can via a shaft, which in conjunction with a delivery mechanism of the Cutting knife 20, 21 stand during the cutting process.

In Fig. 3 ist eine alternative Ausführungsform zu Fig. 2 dargestellt. Der Amboß 26 ist konusförmig ausgebildet und ragt mit seinen Schrägflächen 33 über die Mantelfläche 34 des Gegenhalters 13 hinaus. Dadurch kann erreicht werden, daß an der Schnittstelle auf der Innenseite der Rohre 11 und 11' eine Fase vorgesehen ist. Dadurch kann auch erreicht werden, daß beispielsweise bei Papprohren die letzte Lage besser und sauberer abgeschnitten werden kann. Insgesamt kann durch diese Ausgestaltung eine saubere Schnittkante mit einer gleichzeitigen Fase und eine definierte Innenkante des Rohres 11 herstellbar sein. Dadurch kann eine leichtere Weiterverarbeitung der Rohre 11 ermöglicht sein.An alternative embodiment to FIG. 2 is shown in FIG. 3. The anvil 26 is formed conical and projects with its inclined surfaces 33 over the outer surface 34 of the counter-holder 13. This can be achieved at the interface A chamfer is provided on the inside of the tubes 11 and 11 '. This can can also be achieved that, for example with cardboard tubes, the last layer better and can be cut cleaner. Overall, this configuration can clean cutting edge with a simultaneous chamfer and a defined inner edge of the Tube 11 can be produced. This allows easier processing of the pipes 11 be possible.

Zu Beginn des Schneidvorganges werden die Ambosse 26 über die Zwangsführung 32 aktiv nach außen bewegt, so daß diese sich zumindest teilweise in die Innenmantelfläche 36 des Rohres 11 einpressen. Die Schneidmesser 20, 21 werden von außen radial nach innen auf die Ambosse 26 hinzubewegt, wobei diese auf der Achse 23 zur Schnittstelle 14 geführt werden. Diese können dann beispielsweise - wie in Fig. 3 dargestellt - zum Amboß 26 auf der gemeinsamen Achse 23 positionierbar sein. Alternativ kann vorgesehen sein, daß kurz vor dem Aneinanderanliegen von Amboß 26 und Schneidmesser 20 eine aktive Nachinnenbewegung der Ambosse 26 zumindest geringfügig erfolgt.At the beginning of the cutting process, the anvils 26 are moved over the positive guide 32 actively moved outwards, so that they at least partially into the inner surface 36 press the tube 11. The cutting knives 20, 21 are from the outside moved radially inward towards the anvils 26, these on the axis 23 for Interface 14 are performed. These can then, for example - as shown in Fig. 3 - Can be positioned on the common axis 23 for the anvil 26. Alternatively can be provided that shortly before the anvil 26 and Cutting knife 20 an active inward movement of the anvils 26 at least slightly done.

Zum Überfahren des Gegenhalters 13 und um die nächstfolgende Länge des Rohrabschnittes festzulegen, können die Ambosse 26 durch die Kulisse 32 derart nach innen bewegt werden, daß deren äußere Körperkanten innerhalb der Mantelfläche 34 des Gegenhalters 13 positionierbar sind. Nachdem die Länge eingestellt ist und das Rohr 11 in Drehung gesetzt worden ist, können mit Beginn des Schneidvorganges die Ambosse 26 über die Kulisse 32 nach außen bewegbar sein.To run over the counter holder 13 and the next length of the pipe section to set, the anvils 26 through the backdrop 32 in such a way are moved so that their outer body edges within the lateral surface 34th of the counter holder 13 are positionable. After the length is set and that Pipe 11 has been set in rotation, can start with the cutting process Anvils 26 can be moved outwards via the backdrop 32.
