Description

Die Erfindung betrifft eine Vorrichtung zum Entsorgen von Restdraht bei Bindemaschinen.The invention relates to a device for disposing of residual wire in binding machines.

Bindemaschinen werden bei der Zellstoffproduktion in allen Verpackungslinien eingesetzt. Dabei werden Zellstoffballen, Zellstoffstapel und/oder Zellstoffunits mit verzinktem Stahldraht verschnürt, was in einem so genannten Bindegerüst der Bindemaschine durchgeführt wird. Bisher wurde der Restdraht, der anfällt, wenn der vorhandene Draht nicht mehr ausreicht um einen Ballen vollständig zu umwickeln, aus dem Bindegerüst zurückgefahren und von einem Arbeiter entsorgt. Die DE 1 477 003 sowie die US 2,643,698 zeigen Vorrichtungen zur Herstellung von Drahtschrauben, die u.a. für die Ummantelung von biegsamen Wellen verwendet werden. Eine Entsorgung von Restdraht ist aber nirgends beschrieben.Tying machines are used in pulp production in all packaging lines. Here, pulp bales, pulp stacks and / or pulp units are tied with galvanized steel wire, which is carried out in a so-called binding framework of the binding machine. So far, the remaining wire, which is obtained when the existing wire is no longer sufficient to wrap a bale completely, moved back from the binding scaffolding and disposed of by a worker. The DE 1 477 003 as well as the US 2,643,698 show devices for the production of wire screws, which are used, inter alia, for the sheathing of flexible shafts. However, disposal of residual wire is nowhere described.

Das Entsorgen des Restdrahtes zu vereinfachen ist Aufgabe der vorliegenden Erfindung.To simplify the disposal of the residual wire is the object of the present invention.

Gelöst wird diese Aufgabe mit einer Vorrichtung mit den Merkmalen des Anspruchs 1.This object is achieved with a device having the features of claim 1.

Der Vorteil der erfindungsgemäßen Vorrichtung liegt darin, dass kein Arbeiter einen sperrigen Restdraht entfernen muss, was einerseits Arbeitszeit und andererseits Lagerplatz für den Restdraht erspart, da dieser auf ein relativ kleines Volumen zusammen gedreht wurde.The advantage of the device according to the invention is that no worker has to remove a bulky residual wire, which on the one hand saves working time and on the other hand storage space for the remaining wire, since this was rotated together to a relatively small volume.

In einer bevorzugten Ausführungsform der Erfindung ist unmittelbar an der Vorrichtung ein Auffangbehälter für den zusammen gerollten Draht angeordnet, der bei Bedarf entleert werden kann.In a preferred embodiment of the invention, a collecting container for the rolled-up wire is arranged directly on the device, which can be emptied if necessary.

In einer weiteren bevorzugten Ausführungsform der Erfindung ist die Biegeeinrichtung aus einer Ruheposition in eine in der Bewegungsbahn des Restdrahtes liegende Arbeitsposition bewegbar. In dieser Ausführungsform wird somit die gesamte Biegeeinrichtung aus der Bewegungsbahn zurückgezogen, wenn sie inaktiv ist. Dann kann sich der Bindedraht ungehindert durch die Vorrichtung bewegen. Wenn allerdings ein Rest des Bindedrahtes als Restdraht entsorgt werden soll, wird die Biegeeinrichtung in ihre Arbeitsposition bewegt, in welcher der Restdraht schraubenförmig oder spiralförmig umgeformt wird.In a further preferred embodiment of the invention, the bending device is movable from a rest position into a working position lying in the movement path of the residual wire. Thus, in this embodiment, the entire bender is retracted from the path of travel when inactive. Then the binding wire can move freely through the device. However, if a remainder of the binding wire is to be disposed of as a residual wire, the bending device is moved to its working position, in which the remaining wire is helically or spirally deformed.

In einer alternativen, ebenfalls bevorzugten Ausführungsform der Erfindung weist die Biegeeinrichtung ein Biegeelement auf, das aus einer Ruheposition in eine in der Bewegungsbahn des Restdrahtes liegende Arbeitsposition bewegbar ist. Bei dieser Ausführungsform wird daher nicht die gesamte Biegeeinrichtung in eine Arbeitsposition oder Ruheposition bewegt sondern nur ein Biegeelement, an dem der Restdraht umgebogen wird.In an alternative, likewise preferred embodiment of the invention, the bending device has a bending element which can be moved from a rest position into a working position lying in the movement path of the residual wire. In this embodiment, therefore, not the entire bending device is moved to a working position or rest position but only a bending element on which the remaining wire is bent.

Die Biegeeinrichtung besteht bevorzugt aus wenigstens zwei, vorzugsweise drei Rollen, zwischen denen der Restdraht während des Biegevorganges durchgeführt wird. Das Biegeelement kann dabei von einer dieser Rollen gebildet werden.The bending device preferably consists of at least two, preferably three rollers, between which the remaining wire is carried out during the bending process. The bending element can be formed by one of these roles.

In Verbindung mit der Ausführungsform, bei der nur das Biegeelement und nicht die gesamte Biegeeinrichtung in die Arbeitsposition bzw. Ruheposition bewegt wird, wird dann die als Biegeelement wirkende Rolle in die Arbeitsposition bewegt.In conjunction with the embodiment in which only the bending element and not the entire bending device is moved to the working position or rest position, then acting as a bending element roller is moved to the working position.

Zusätzlich oder alternativ kann die Biegeeinrichtung eine ebene oder gekrümmte Auflauffläche für den Restdraht aufweisen. An dieser Auflauffläche kann dann entweder die Biegung des Restdrahtes hergestellt oder fertig gestellt werden.Additionally or alternatively, the bending device may have a flat or curved ramp surface for the remaining wire. Either the bending of the residual wire can then be made or completed at this ramp surface.

Weitere Merkmale und Vorteile der vorliegende Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels der Erfindung mit Bezugnahme auf die Zeichnung.Further features and advantages of the present invention will become apparent from the following description of a preferred embodiment of the invention with reference to the drawings.

In den Zeichnungen ist eine Vorrichtung dargestellt, die ein Maschinengestell 1 aufweist. An diesem Maschinengestell 1 ist eine rohrförmige Einlaufführung 2 für einen Draht 3 angeordnet, der bei normalem Betrieb der Bindemaschine ungehindert durchläuft, bei Bedarf aber als Restdraht schraubenförmig oder spiralförmig eingerollt werden kann. Im Anschluss an diese Einlaufführung 2 befindet sich eine Biegeeinrichtung 4, welche im dargestellten Ausführungsbeispiel aus drei Rollen 5, 6, 7 besteht.In the drawings, a device is shown which has a machine frame 1. At this machine frame 1, a tubular inlet guide 2 is arranged for a wire 3, which passes unhindered in normal operation of the binding machine, but if necessary as a remaining wire helical or spiral can be rolled. Following this inlet guide 2 is a bending device 4, which consists of three rollers 5, 6, 7 in the illustrated embodiment.

Diese Biegeeinrichtung 4 mit den drei Rollen 5, 6, 7, befindet sich, wenn sie außer Betrieb ist, in einer zurückgezogenen Ruheposition, in welcher der zum Verschnüren von Zellstoffballen, Zellstoffstapeln oder Zellstoffunits verwendete Bindedraht 3 ungehindert durch die erfindungsgemäße Vorrichtung durchlaufen und durch eine Austrittsöffnung 8 verlassen kann. Wenn der vorhandene Draht 3 allerdings nicht mehr lang genug ist, um z.B. einen Zellstoffballen zu verschnüren, wird dieser Restdraht 3 soweit zurückgezogen, dass sein Anfang in der Einlaufführung 2 liegt und die Biegeeinrichtung 4 ungehindert in ihre Arbeitsposition bewegt werden kann. Dies kann beispielsweise mit Hilfe von Elektromotoren oder einem Druckmittelantrieb, wie Hydraulik- oder Pneumatikzylindern, erfolgen. Anschließend wird der Restdraht 3 wieder in seiner ursprünglichen Richtung vorgeschoben und gelangt zunächst zwischen die zwei Rollen 5 und 7, welche als Führungsrollen dienen. In weiterer Folge trifft der Restdraht 3 auf die Rolle 6, welche erfindungsgemäß als Biegeelement wirkt und den zwischen den Rollen 5 und 7 geführten Restdraht 3 nach oben umbiegt.This bending device 4 with the three rollers 5, 6, 7, when it is out of service, is in a retracted rest position, in which the binding wire 3 used for strapping pulp bales, pulp stacks or pulp units passes unhindered through the device according to the invention and through a Leave outlet 8. However, if the existing wire 3 is no longer long enough to tie a pulp bale, for example, this remnant wire 3 will be withdrawn to such an extent that its beginning lies in the inlet guide 2 and the bending device 4 can be moved unhindered into its working position. This can be done for example by means of electric motors or a pressure medium drive, such as hydraulic or pneumatic cylinders. Subsequently, the remaining wire 3 is advanced again in its original direction and first passes between the two rollers 5 and 7, which serve as guide rollers. Subsequently, the remaining wire 3 strikes the roller 6, which according to the invention as Bending element acts and the guided between the rollers 5 and 7 remaining wire 3 bends upwards.

Durch eine geeignete Profilierung der Rollen 5, 6, 7 oder noch besser durch eine leichte Schrägstellung der Rolle 6 kann bewirkt werden, dass der Restdraht 3 etwas aus der Biegeebene ausgelenkt und dadurch schraubenförmig eingerollt wird.By a suitable profiling of the rollers 5, 6, 7 or even better by a slight inclination of the roller 6 can be effected that the remaining wire 3 is slightly deflected out of the bending plane and thereby helically rolled.

Grundsätzlich wäre es natürlich auch möglich, dass nicht die gesamte Biegeeinrichtung 4 aus der Arbeitsposition in einer Ruheposition bewegt wird, sondern beispielsweise nur die Rolle 6 nach unten in eine Ruheposition geschwenkt wird, da die geradlinige Bewegung des zum Verschnüren verwendeten Drahtes 3 durch die Rolle in 5 und 7 nicht behindert wird.In principle, it would of course also possible that not the entire bending device 4 is moved from the working position in a rest position, but for example, only the roller 6 is pivoted down to a rest position, since the rectilinear movement of the wire used for strapping 3 by the role in 5 and 7 is not hindered.

Schließlich wäre es auch noch möglich, die gesamte Vorrichtung aus der Bewegungsbahn des Drahtes 3 zu bewegen, so dass dieser bei normalem Betrieb der Bindemaschine an der Vorrichtung vorbei läuft. Falls ein Stück Restdraht 3 zusammengerollt werden soll, wird die Maschine in die Arbeitsposition verschoben, der Restdraht 3 läuft durch eine vorzugsweise trichterförmige Einlaufführung 2 und wird anschließend wie beschrieben eingerollt.Finally, it would also be possible to move the entire device out of the path of movement of the wire 3 so that it passes the device during normal operation of the binding machine. If a piece of residual wire 3 is to be rolled up, the machine is moved to the working position, the remaining wire 3 passes through a preferably funnel-shaped inlet guide 2 and is then rolled as described.

Weiteres wäre es bei der Erfindung auch möglich, anstelle der Rolle 6, welche das aktive Biegeelement darstellt, ein statisches Biegeelement, beispielsweise in Form einer Halterung mit einer ebenen oder gekrümmten Auflauffläche für den Restdraht 3 zu verwenden. Es ist im Rahmen der Erfindung des weiteren auch noch möglich, eine derartige Auflauffläche im Anschluss an die Rolle 6 anzuordnen, um den Restdraht 3 weiter zu verbiegen oder kontrolliert aus der Biegeeinrichtung 4 herauszuführen.It would also be possible in the invention also, instead of the roller 6, which is the active bending element, to use a static bending element, for example in the form of a holder with a flat or curved ramp surface for the remaining wire 3. It is also within the scope of the invention also possible to arrange such a ramp surface following the roller 6 to further bend the remaining wire 3 or led out of the bending device 4 controlled.

Wenigstens eine der drei Rollen 5, 6, 7 kann angetrieben sein, damit der gesamte Restdraht 3 ohne weiteren Antrieb oder zur Unterstützung eines anderen Antriebes durch die Biegeeinrichtung 4 durchläuft und eingerollt wird. Nach dem dies erfolgt ist, fällt der eingerollte Restdraht seitlich neben der Biegeeinrichtung 4 in einen Auffangbehälter 9. Dieser Auffangbehälter 9 muss vom Bedienungspersonal von Zeit zu Zeit entleert werden, was aber aufgrund der geringen Sperrigkeit bzw. des kleinen Volumens der Restdrahtstücke sehr einfach und in wesentlich längeren Intervallen durchgeführt werden kann.At least one of the three rollers 5, 6, 7 can be driven, so that the entire remaining wire 3 without further drive or to support another drive passes through the bending device 4 and is rolled. After this is done, the rolled-up remaining wire falls laterally next to the bending device 4 in a receptacle 9. This receptacle 9 must be emptied by the operator from time to time, but due to the small bulkiness and the small volume of the remaining pieces of wire very easy and in much longer intervals can be performed.
