Definitions
- the invention relates to a winding device for winding cut strapping wires on a square bale, with a winding shaft which has finger elements protruding from a lateral surface of the winding shaft for gripping and winding up the strapping wires on the lateral surface of the winding shaft.
- Such a winding device is used in particular to remove the strapping wires from square bales from pieces of waste paper.
- the cut strapping wires on the outside of the square bale are gripped by the finger elements and wound onto the outer surface of the winding shaft.
- the wound strapping wires are then discharged so that the waste paper freed from the strapping wires can be processed further.
- the object of the invention is to further develop the winding device of the type mentioned at the outset in such a way that the strapping wires are removed more reliably using structurally simple means.
- the winding shaft has a first set of finger elements and a second set of finger elements, the first set of finger elements with respect to a central plane of the winding shaft in the axial direction towards one end face of the winding shaft and the second set of finger elements with respect to the central plane of the winding shaft in the axial direction Direction to the other end of the winding shaft is offset.
- the invention provides a first and a second set, each with at least two finger elements, the first and second set each being arranged eccentrically on the winding shaft, that is to say moved from the center plane in the axial direction outward to the respective end face.
- the invention is based in particular on the finding that the finger elements offset from the center cause a flatter pulling angle of the strapping wires in the corner regions of the square bale, since the finger elements engage closer to the two corner regions between the top side and the side surfaces. This reduces the risk of the strapping wire tearing off while being pulled off and wound onto the winding shaft.
- additional possibilities are created to capture the strapping wires on the square bale. This is particularly advantageous when the square bales are brought to the wrapping device in a position inclined to the transport direction.
- the axial distance between the center plane and the first or second set of finger elements is in relation to the total length of the winding shaft for one preferred embodiment between 1/20 and 1/2, in particular between 1/10 and 1/4.
- This design also has the advantage that the deflection angle of the strapping wire when pulling off is small enough that undesired tearing of the strapping wire is reliably prevented.
- the first set and the second set each have at least two, preferably three, finger elements spaced apart from one another in the circumferential direction of the winding shaft.
- the first and second sets preferably each have three finger elements at regular angular intervals.
- the finger elements can be transferred between an engagement position protruding from the outer surface of the winding shaft for gripping and winding up the strapping wires and a stripping position withdrawn under the outer surface of the winding shaft for stripping the strapping wires from the outer surface of the winding shaft. Accordingly, after winding the strapping wire onto the winding shaft, the first and second set of finger elements can be placed under the outer surface of the winding shaft, i.e. the envelope of the winding shaft, which is circular in cross section, is lowered, which enables stripping of the wound strapping wire from the winding shaft.
- the winding shaft can have a ribbed outer surface.
- the finger elements in the engagement position are more than 45.5 mm, preferably more than 50 mm, in particular more than 55 mm, for example essentially 60 mm, from the lateral surface of the Protrude winding shaft.
- a stripping device is provided for stripping the strapping wires from the outer surface of the winding shaft in the stripping position of the finger elements. In this way, the strapping wires can be rejected before the waste paper is further processed after the square bale has been dissolved.
- the stripping device has a stripping ring and a linear drive for displacing the stripping ring along the outer surface of the winding shaft.
- the stripping ring can thus be guided in the axial direction along the outside of the winding shaft in order to strip the strapping wire from the winding shaft.
- Fig. 1 shows schematically a device 1 for cutting and removing strapping wires 2 from one wrapped therewith Square bale 3 (cf. Fig. 2 , 3rd ).
- the device 1 has a transport device 4 with a conveyor belt 5 for transporting the square bales 3 in the conveying direction 6.
- a cutting device 7 (cf. Fig. 4 ) provided with a rotating cutting knife 8 for cutting open the strapping wires 2 on the underside of the square bale 3 (cf. Fig. 4 ).
- a winding device 9 for winding and discharging the strapping wires 2 is arranged after the transport device 4 and the cutting device 7.
- the square bales 3 are fed to a further processing device 10 for further processing of the waste paper after the square bales 3 have been dissolved.
- the further processing of the waste paper is well known in the prior art, so that an explanation in this regard is dispensed with.
- the winding shaft 11 is rotated with the finger elements 13, the finger elements 13 penetrating into the square bale 3 and gripping the strapping wire 2 by the rotation and winding it onto the outer surface 12 of the winding shaft 11.
- the first set 13a of finger elements 13 is offset with respect to a central plane 15 perpendicular to the axis of rotation 14 of the winding shaft 11 in the middle between the opposite end faces 16 of the winding shaft 11 in the axial direction (ie in the direction of the axis of rotation 14) outwards (cf. Fig. 3 ).
- the winding device 9 also has a pressure flap 17 for pressing the strapping wire 2 against the outer surface 12 of the winding shaft 11 in order to compact the strapping wires 2.
- the pressure flap 17 is adjustable by means of a drive 18.
- the first set 13a and the second set 13b each have exactly three finger elements 13 spaced apart from one another in the circumferential direction of the winding shaft 11 in the embodiment variant shown.
- the finger elements 13 are movable between an engagement position protruding from the outer surface 12 of the winding shaft 11 for gripping and winding up the strapping wires and a stripping position retracted under the outer surface 12 of the winding shaft 11 for stripping the strapping wires from the outer surface of the winding shaft.
- the finger elements 13 in the embodiment shown have serrations 19 at the inner end which mesh with a gear wheel 20. By rotating the gear 20, the finger elements 13 can be moved from the engagement to the stripping position and vice versa.
- the finger elements 13 project in the engagement position essentially 60 mm from the lateral surface 12 of the winding shaft 11.
- the winding device 9 also has a stripping device 21 for stripping the wound strapping wires 2 from the outer surface 12 of the winding shaft 11 in the stripping position of the finger elements 13.
- the stripping device 21 has a stripping ring 22 and a linear drive 23 for displacing the stripping ring 22 along the lateral surface 12 of the winding shaft 11.
- the linear drive 23 By actuating the linear drive 23 in the axial direction of the winding shaft 11, cf. Arrow 24 in Fig. 2 , the wound strapping wire 2 through the wiper ring 22 stripped from the winding shaft 11.
- Fig. 6 shows the outwardly displaced state of the stripping ring 22, in which the wound strapping wire 2 is released from the winding shaft 11 and can be discharged in the direction of arrow 27.
- Fig. 3 shows schematically the grip of a strapping wire 2, which is wrapped around the square bale 3, for example from pieces of waste paper. Due to the finger elements 13 moved outwards from the center, a comparatively flat pull-off angle a is achieved at the corner regions 25 of the square bale 3, as a result of which the strapping wire 2 is less frequently torn off when pulling off and winding up. The metal content in the further processing device 10 can thus be significantly reduced.
- Fig. 4 schematically shows the approach of square bales 3 of different sizes along the transport device 4 to the winding shaft 11. Because of the different width of the square bales 3, a sufficient width of the conveyor belt 5 must be ensured.
- the off-center finger elements 13 on the winding shaft 11 make it easier to grasp the strapping wires 2 on such square bales 3, in particular if they have been placed on the conveyor belt 5 in an inclined position relative to the conveying direction. This is illustrated by the tracks 26 of the finger elements 13 with respect to the square bales 3.

Description
Die Erfindung betrifft eine Wickelvorrichtung zum Aufwickeln von aufgeschnittenen Umreifungsdrähten an einem Quaderballen, mit einer Wickelwelle, welche von einer Mantelfläche der Wickelwelle vorstehende Fingerelemente zum Ergreifen und Aufwickeln der Umreifungsdrähte an der Mantelfläche der Wickelwelle aufweist.The invention relates to a winding device for winding cut strapping wires on a square bale, with a winding shaft which has finger elements protruding from a lateral surface of the winding shaft for gripping and winding up the strapping wires on the lateral surface of the winding shaft.
Weiters betrifft die Erfindung eine Vorrichtung zum Aufschneiden und Entfernen von Umreifungsdrähten von einem damit umreiften Quaderballen, aufweisend:
- eine Transportvorrichtung zum Transportieren der Quaderballen;
- eine Schneidvorrichtung zum Aufschneiden der Umreifungsdrähte des Quaderballens; und
- eine Wickelvorrichtung.
- a transport device for transporting the square bales;
- a cutting device for cutting open the strapping wires of the square bale; and
- a winding device.
Eine solche Wickelvorrichtung wird insbesondere zum Entfernen der Umreifungsdrähte von Quaderballen aus Altpapierstücken verwendet. Die aufgeschnittenen Umreifungsdrähte an der Außenseite des Quaderballens werden von den Fingerelementen erfasst und auf die Mantelfläche der Wickelwelle aufgewickelt. Anschließend werden die aufgewickelten Umreifungsdrähte ausgeschleust, so dass das von den Umreifungsdrähten befreite Altpapier weiterverarbeitet werden kann.Such a winding device is used in particular to remove the strapping wires from square bales from pieces of waste paper. The cut strapping wires on the outside of the square bale are gripped by the finger elements and wound onto the outer surface of the winding shaft. The wound strapping wires are then discharged so that the waste paper freed from the strapping wires can be processed further.
In der Praxis hat sich jedoch gezeigt, dass ein Teil der Umreifungsdrähte nicht bzw. nicht vollständig vom Altpapier getrennt wurde. Dies hat jedoch nachteilige Auswirkungen auf die Weiterverarbeitung des Altpapiers. Der Metallanteil im Altpapier führt insbesondere zu einem hohen Verschleiß bei der Weiterverarbeitung, womit kürzere Standzeiten der Anlage einhergehen.In practice, however, it has been shown that part of the strapping wire has not been or was not completely separated from the waste paper. However, this has adverse effects on the processing of the waste paper. The metal content in the waste paper leads in particular to a high level of wear during further processing, which means that the system has a shorter service life.
Deshalb wurden bereits verschiedene Überlegungen angestellt, wie der Metallanteil nach der Wickelvorrichtung gesenkt werden kann. Beispielsweise wäre es möglich, das Abziehen und Aufwickeln der Umreifungsdrähte zu trennen, also zunächst die Umreifungsdrähte seitlich von den Quaderballen abzuziehen und die Umreifungsdrähte erst danach aufzuwickeln. Dies würde ein gründlicheres Entfernen der Umreifungsdrähte ermöglichen, ginge jedoch mit aufwendigen Modifikationen der Anlage einher, weshalb diese Lösung aus ökonomischen Gründen nachteilig wäre.For this reason, various considerations have already been made as to how the metal content can be reduced after the winding device. For example, it would be possible to separate the stripping and winding up of the strapping wires, that is to say first of all pulling off the strapping wires laterally from the square bales and only then winding up the strapping wires. This would allow the strapping wires to be removed more thoroughly however, this involves expensive modifications to the system, which is why this solution would be disadvantageous for economic reasons.
Die Aufgabe der Erfindung besteht darin, die Wickelvorrichtung der eingangs angeführten Art derart weiterzuentwickeln, dass das Entfernen der Umreifungsdrähte mit konstruktiv einfachen Mitteln zuverlässiger gestaltet wird.The object of the invention is to further develop the winding device of the type mentioned at the outset in such a way that the strapping wires are removed more reliably using structurally simple means.
Diese Aufgabe wird durch eine Wickelvorrichtung mit den Merkmalen von Anspruch 1 gelöst. Bevorzugte Ausführungsformen sind in den abhängigen Ansprüchen angegeben.This object is achieved by a winding device with the features of claim 1. Preferred embodiments are specified in the dependent claims.
Erfindungsgemäß weist die Wickelwelle einen ersten Satz von Fingerelementen und einen zweiten Satz von Fingerelementen auf, wobei der erste Satz von Fingerelementen bezüglich einer Mittelebene der Wickelwelle in axialer Richtung zur einen Stirnseite der Wickelwelle hin und der zweite Satz von Fingerelementen bezüglich der Mittelebene der Wickelwelle in axialer Richtung zur anderen Stirnseite der Wickelwelle hin versetzt ist.According to the invention, the winding shaft has a first set of finger elements and a second set of finger elements, the first set of finger elements with respect to a central plane of the winding shaft in the axial direction towards one end face of the winding shaft and the second set of finger elements with respect to the central plane of the winding shaft in the axial direction Direction to the other end of the winding shaft is offset.
Demnach sieht die Erfindung einen ersten und einen zweiten Satz mit jeweils zumindest zwei Fingerelementen vor, wobei der erste und zweite Satz jeweils außermittig an der Wickelwelle angeordnet ist, d.h. von der Mittelebene in axialer Richtung nach außen zur jeweiligen Stirnseite gerückt ist. Der Erfindung liegt insbesondere die Erkenntnis zugrunde, dass die von der Mitte nach außen versetzten Fingerelemente einen flacheren Abziehwinkel der Umreifungsdrähte in den Eckbereichen des Quaderballens bewirken, da die Fingerelemente näher an den beiden Eckbereichen zwischen der Oberseite und den Seitenflächen angreifen. Dies verringert die Gefahr eines Abreißens des Umreifungsdrahtes beim gleichzeitigen Abziehen und Aufwickeln auf die Wickelwelle. Darüber hinaus werden zusätzliche Möglichkeiten geschaffen, die Umreifungsdrähte am Quaderballen zu erfassen. Dies ist insbesondere dann von Vorteil, wenn die Quaderballen in einer schräg zur Transportrichtung gestellten Lage an die Wickelvorrichtung herangeführt werden.Accordingly, the invention provides a first and a second set, each with at least two finger elements, the first and second set each being arranged eccentrically on the winding shaft, that is to say moved from the center plane in the axial direction outward to the respective end face. The invention is based in particular on the finding that the finger elements offset from the center cause a flatter pulling angle of the strapping wires in the corner regions of the square bale, since the finger elements engage closer to the two corner regions between the top side and the side surfaces. This reduces the risk of the strapping wire tearing off while being pulled off and wound onto the winding shaft. In addition, additional possibilities are created to capture the strapping wires on the square bale. This is particularly advantageous when the square bales are brought to the wrapping device in a position inclined to the transport direction.
Um auch solche Quaderballen zuverlässig von den Drähten an der Außenseite des Quaderballens zu befreien, welche nicht im rechten Winkel zur Förderrichtung herangeführt werden, beträgt der axiale Abstand zwischen der Mittelebene und dem ersten bzw. zweiten Satz von Fingerelementen im Verhältnis zur Gesamtlänge der Wickelwelle bei einer bevorzugten Ausführungsform jeweils zwischen 1/20 und 1/2, insbesondere zwischen 1/10 und 1/4. Diese Ausführung birgt darüber hinaus den Vorteil, dass der Umlenkwinkel des Umreifungsdrahtes beim Abziehen gering genug ist, dass ein unerwünschtes Abreißen des Umreifungsdrahtes zuverlässig verhindert wird.In order to reliably free such square bales from the wires on the outside of the square bale, which are not brought at right angles to the conveying direction, the axial distance between the center plane and the first or second set of finger elements is in relation to the total length of the winding shaft for one preferred embodiment between 1/20 and 1/2, in particular between 1/10 and 1/4. This design also has the advantage that the deflection angle of the strapping wire when pulling off is small enough that undesired tearing of the strapping wire is reliably prevented.
Zur zuverlässigen Erfassung der Umreifungsdrähte ist es günstig, wenn der erste Satz und der zweite Satz jeweils zumindest zwei, vorzugsweise drei, in Umfangrichtung der Wickelwelle voneinander beabstandete Fingerelemente aufweist. Bevorzugt weisen der erste und zweite Satz jeweils drei Fingerelemente in regelmäßigen Winkelabständen ab.For reliable detection of the strapping wires, it is advantageous if the first set and the second set each have at least two, preferably three, finger elements spaced apart from one another in the circumferential direction of the winding shaft. The first and second sets preferably each have three finger elements at regular angular intervals.
Gemäß einer bevorzugten Ausführungsform sind die Fingerelemente zwischen einer von der Mantelfläche der Wickelwelle vorstehenden Eingriffsstellung zum Ergreifen und Aufwickeln der Umreifungsdrähte und einer unter die Mantelfläche der Wickelwelle zurückgezogenen Abstreifstellung zum Abstreifen der Umreifungsdrähte von der Mantelfläche der Wickelwelle überführbar. Demnach können der erste und zweite Satz von Fingerelementen nach dem Aufwickeln des Umreifungsdrahtes auf die Wickelwelle unter die Mantelfläche der Wickelwelle, d.h. die im Querschnitt kreisförmige Umhüllende der Wickelwelle, abgesenkt werden, wodurch ein Abstreifen des aufgewickelten Umreifungsdrahtes von der Wickelwelle ermöglicht wird. Die Wickelwelle kann eine gerippte Mantelfläche aufweisen.According to a preferred embodiment, the finger elements can be transferred between an engagement position protruding from the outer surface of the winding shaft for gripping and winding up the strapping wires and a stripping position withdrawn under the outer surface of the winding shaft for stripping the strapping wires from the outer surface of the winding shaft. Accordingly, after winding the strapping wire onto the winding shaft, the first and second set of finger elements can be placed under the outer surface of the winding shaft, i.e. the envelope of the winding shaft, which is circular in cross section, is lowered, which enables stripping of the wound strapping wire from the winding shaft. The winding shaft can have a ribbed outer surface.
Um das Eindringen der Fingerelemente in den Quaderballen zu verbessern, ist es günstig, wenn die Fingerelemente in der Eingriffsstellung mehr als 45,5 mm, vorzugsweise mehr als 50 mm, insbesondere mehr als 55 mm, beispielsweise im Wesentlichen 60 mm, von der Mantelfläche der Wickelwelle vorstehen.In order to improve the penetration of the finger elements into the square bale, it is favorable if the finger elements in the engagement position are more than 45.5 mm, preferably more than 50 mm, in particular more than 55 mm, for example essentially 60 mm, from the lateral surface of the Protrude winding shaft.
Um den aufgewickelten Umreifungsdraht von der Wickelwelle zu entfernen, ist es günstig, wenn eine Abstreifeinrichtung zum Abstreifen der Umreifungsdrähte von der Mantelfläche der Wickelwelle in der Abstreifstellung der Fingerelemente vorgesehen ist. Auf diese Weise können die Umreifungsdrähte ausgeschleust werden, bevor das Altpapier nach Auflösung des Quaderballens weiterverarbeitet wird.In order to remove the wound strapping wire from the winding shaft, it is favorable if a stripping device is provided for stripping the strapping wires from the outer surface of the winding shaft in the stripping position of the finger elements. In this way, the strapping wires can be rejected before the waste paper is further processed after the square bale has been dissolved.
Gemäß einer bevorzugten Ausführungsform weist die Abstreifeinrichtung einen Abstreifring und einen Linearantrieb zum Verschieben des Abstreifrings entlang der Mantelfläche der Wickelwelle auf. Somit kann der Abstreifring in axialer Richtung entlang der Außenseite der Wickelwelle geführt werden, um den Umreifungsdraht von der Wickelwelle abzustreifen.According to a preferred embodiment, the stripping device has a stripping ring and a linear drive for displacing the stripping ring along the outer surface of the winding shaft. The stripping ring can thus be guided in the axial direction along the outside of the winding shaft in order to strip the strapping wire from the winding shaft.
