Abstract

Two cutter bars (11) are mounted displaceably relative to one another in a guiding slot of an elongate support. The cutters (12) of the cutter bars extend transversely with respect to the longitudinal extent of the support and their blades are arranged with an opposite inclination in such a way that the cutters are able to interact in the manner of claws, in order to seize the binding wires of the waste paper bales (A). The cutters are thus used for penetrating the waste paper bale in order to seize the binding wires in succession so that, after the cutter bars, including the supports, have been drawn away from the waste paper bale, the binding wires can be positioned at a point at which they can be seized by a winding mandrel. In this arrangement, the binding wires are additionally limited to a confined space at said point by means of a guiding nip formed between two guide rollers (4). As a result, it is possible to use a slotted winding mandrel or two parallel winding mandrels spaced apart at a small mutual distance, in whose slot or nip the binding wires can be received readily and reliably. <IMAGE>

Description

Die Erfindung betrifft eine Einrichtung zur Entdrahtung von Altpapierballen entsprechend dem Oberbegriff des Patentan­spruchs 1. Eine solche Einrichtung ist bekannt aus der DE-OS 37 07 966. Bei dieser Einrichtung sind als Schneideinrichtung zwei gegeneinander in verschiedenen Richtungen verschiebbare Messer­balken mit sehr vielen Zähnen vorgesehen, die wie bei einem Haarschneideapparat zusammenwirken. Diese Messerzähne sollen in den Altpapierballen eingedrückt werden, um dann durch Betätigen der Messerbalken die den Altpapierballen umfassenden Binde­drähte zu erfassen. Dies ist aber ein sehr schwieriger und auf keinen Fall 100 %ig sicher durchzuführender Vorgang. Wenn die Drähter sicher erfaßt sind, werden sie durch die Messerbal­ken-Einrichtung so genau positioniert, daß sie in den Schlitz eines Wickelzylinders bzw. in den zwischen zwei Wickeldornen gebildeten Zwischenraum gelangen können, wenn man die Wickel­einrichtung quer zu den Drähten verschiebt. Es ist zu diesem Zweck auch ein sehr langer Verschiebeweg der Wickeleinrichtung nötig, um alle Drähte zu erfassen.The invention relates to a device for unwiring waste paper bales according to the preamble of claim 1. Such a device is known from DE-OS 37 07 966. In this device, two cutter bars with a large number of teeth which can be displaced in different directions are provided as cutting devices interact like a hair clipper. These knife teeth are to be pressed into the waste paper bale in order to then capture the binding wires comprising the waste paper bale by actuating the cutter bar. However, this is a very difficult and by no means 100% safe process. When the wires are securely gripped, they are positioned by the cutter bar device so precisely that they can get into the slot of a winding cylinder or into the space formed between two winding mandrels when the winding device is moved transversely to the wires. For this purpose, a very long displacement path of the winding device is necessary to grasp all the wires.

Die Aufgabe der Erfindung ist es, den Erfassungsvorgang und den Wickelvorgang wesentlich zu vereinfachen bzw. sicherer zu ge­stalten.The object of the invention is to simplify the detection process and the winding process considerably or to make it safer.

Es sind noch verschiedene andere Einrichtungen mit ähnlichen Wickelvorrichtungen bekannt, die aber im ganzen recht umfang­reich und kompliziert aufgebaut sind, weshalb diese Einrichtun­gen sehr teuer sind, ohne daß sie eine ausreichende Betriebs­sicherheit und Standzeit (Betriebsdauer) bzw. Sicherheit gegen Reparaturanfälligkeit gewährleisten können.There are various other devices with similar winding devices known, but the whole is quite extensive and complicated, which is why these devices are very expensive, without they can ensure sufficient operational reliability and service life (operating time) or security against repairs.

Die genannte Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Patentanspruchs 1 gelöst.The stated object is achieved according to the invention by the features of the characterizing part of patent claim 1.

Nachfolgend wird die Erfindung anhand der Figuren der Zeichnung in einem Ausführungsbeispiel erläutert. Dabei stellt

  • Fig. 1 prinzipmäßig eine Ansicht,
  • Fig. 2 eine Draufsicht und
  • Fig. 3 eine Einzelheit eines doppeltwirkenden Hydraulik-Zylinders
    dar.
The invention is explained below with reference to the figures of the drawing in an exemplary embodiment. It poses
  • 1 is a view in principle,
  • Fig. 2 is a plan view and
  • Fig. 3 shows a detail of a double-acting hydraulic cylinder
    represents.

Es ist eine langgestreckte Trägereinrichtung 2 vorgesehen, die zur Haltung und Führung der mit den Messern 12 versehenen Mes­serbalken 11 dient. Dabei sind die Messer 12 und deren Schnei­den gegeneinander gerichtet und gegeneinander, d.h. in ent­gegengesetzten Richtungen verschieblich bzw. verfahrbar ge­halten, in diesem Fall von einer bzw. je einer Hydraulik-Kol­ben-Zylinder-Einheit 22, die an der Trägereinrichtung 2 be­festigt sind. Im Messerbalken 11 sind parallel zu einer Seiten­fläche - in diesem Fall vertikal - des Altpapierballens A neben diesem verfahrbar. Dabei liegt der Ballen A auf einem Ballen­förderer B. Da der gesamte Trenn- und Aufnahmevorgang für die Ballendrähte sehr schnell vor sich geht, braucht der Ballen­förderer nicht angehalten zu werden, sondern man kann den Alt­papierballen durch eine Sperre C stoppen, welcher aus einem hereinschwenkbaren Arm besteht.An elongated carrier device 2 is provided, which serves to hold and guide the knife bars 11 provided with the knives 12. The knives 12 and their cutting edges are directed towards one another and are held against one another, ie displaceably or displaceably in opposite directions, in this case by one or each hydraulic piston-cylinder unit 22 which are fastened to the carrier device 2. In the cutter bar 11 parallel to a side surface - in this case vertically - of the waste paper bale A can be moved next to it. The bale A lies on a bale conveyor B. Since the entire separation and take-up process for the bale wires takes place very quickly, the bale conveyor does not need to be stopped, but the waste paper bale can be stopped by a lock C, which comes from a swing-out arm consists.

Die Trägereinrichtung 2 weist in ihrer Längsrichtung einen Schlitz auf, durch den die Messerbalken 11, die an der Zylin­der-Kolbenstange 26 befestigt sind, hindurchgreifen. Die Trä­gereinheit 2′ ist mittels Hydraulik-Kolben-Zylinder-Einheit 21 quer zur genannten Seitenfläche des Ballens verschiebbar, wobei sie noch mittels Rohr 16 in einer Parallelführungseinheit 6 geführt ist. Die Wickeleinheit 3 weist ein rahmenförmiges Wicklergestell 8 auf, an dem auch Abstreifer 5 für die von dem geschlitzten Wickelzylinder 27 aufgewickelten Bindedrähte be­festigt ist. Über eine Stützkonsole 14 ist der Antriebsmotor 15 für den Wickelzylinder 27 auf dem beweglichen Teil des Wickler­gestells befestigt und treibt über die Kupplungsscheiben 9 und 9′ die Welle des Wickelzylinders 27 an. Zum Heben und Senken der Einheit aus Elektromotor 15 und Wickelzylinder 27 dienen zwei Hydraulik-Kolben-Zylinder-Einheiten 19, die zu beiden Seiten des Wicklergestells 8 in dessen seitlichen Rahmenteilen 36 angeordnet sind.The carrier device 2 has a slot in its longitudinal direction through which the cutter bars 11, which are fastened to the cylinder piston rod 26, extend. The carrier unit 2 'is displaceable by means of hydraulic piston-cylinder unit 21 transversely to the mentioned side surface of the bale, wherein it is still guided by means of tube 16 in a parallel guide unit 6. The winding unit 3 has a frame-shaped winder frame 8, to which wipers 5 for the binding wires wound up by the slotted winding cylinder 27 are also fastened. About a support bracket 14, the drive motor 15 for the winding cylinder 27 is attached to the movable part of the winder frame and drives the shaft of the winding cylinder 27 via the clutch discs 9 and 9 '. Two hydraulic piston-cylinder units 19, which are arranged on both sides of the winder frame 8 in the side frame parts 36 thereof, are used to raise and lower the unit comprising the electric motor 15 and the winding cylinder 27.

Zu beiden Seiten der Verschiebeebene D am Messerbalken 11 be­findet sich je eine in Lagern 18 und 17 gelagerte Leitrolle 4.There is a guide roller 4 mounted in bearings 18 and 17 on both sides of the displacement plane D on the cutter bar 11.

In der Ausgangsstellung werden die Messerbalken 11 in der ge­zeichneten Stellung in einer Position oberhalb bzw. unterhalb des Ballens A positioniert und dann die Messer 12 gegeneinander gefahren, wobei sie sich die Bindedrähte greifen. Nach Abziehen der Bindedrähte durch Zurückfahren der Messerbalken mit der Trägereinheit 2′ sind die Drähte durch die Leitrollen 4 relativ genau positioniert, so daß der Wickelzylinder 27 herabgesenkt werden und am Schlitz die Drähte ergreifen kann, die dann auf dem Wickelzylinder aufgewickelt werden. Durch Hochziehen des Zylinders werden dann die Drähte als ein Bündel von dem Ab­streifer 5 vom Wickelzylinder 27 abgestreift. Sie fallen nach unten und werden dort in einer Wanne aufgefangen.In the starting position, the knife bars 11 are positioned in the position shown in a position above or below the bale A and then the knives 12 are moved against one another, gripping the binding wires. After removing the binding wires by retracting the cutter bar with the carrier unit 2 ', the wires are positioned relatively precisely by the guide rollers 4 so that the winding cylinder 27 can be lowered and the wires can take hold of the slot, which are then wound on the winding cylinder. By pulling up the cylinder, the wires are then stripped from the winding cylinder 27 as a bundle by the stripper 5. They fall down and are caught in a tub.

Auf der anderen Seite des Ballenförderers B ist die Messervor­richtung angeordnet. Sie besteht aus einem parallel zum Wickel­zylinder bzw. der Trägereinrichtung 2 angeordnetem Rohr 30 mit einem Längsschlitz, zu dessen beiden Seiten sich je eine Reihe von Dornen 32 befindet. Durch den Schlitz greift ein Messer­balken 33, der an einer Betätigungsstange 34 der Hydraulik-Kol­ben-Zylinder-Einheit 35 befestigt ist. Das Rohr 30 der Trenn­einheit 31 ist dabei ebenfalls durch eine Hydraulik-Kolben-Zy­linder-Einheit 38 quer zum Altpapierballen verschiebbar, wobei noch eine vorangehend beschriebene Parallelführungseinheit 6 vorgesehen ist.The knife device is arranged on the other side of the bale conveyor B. It consists of a tube 30 arranged parallel to the winding cylinder or the carrier device 2 and having a longitudinal slot, on each side of which there is a row of mandrels 32. A knife bar 33 extends through the slot and is attached to an actuating rod 34 of the hydraulic piston-cylinder unit 35. The tube 30 of the separating unit 31 can also be displaced transversely to the waste paper bale by a hydraulic piston-cylinder unit 38, a parallel guide unit 6 described above being provided.

Ähnlich wie im Falle der Messerbalken 11 ist auch hier ein Messerbalken 33 unterhalb des Altpapierballens positioniert, ehe er in diesen hineinfährt, um die Bindedrähte an den als Widerlager dienenden Dornen 32 zu zertrennen. Die Eindringtiefe dürfte jeweils bei etwa 50 mm liegen, um auch tief eingeführte Drähte mit Sicherheit zu erfassen.Similar to the case of the cutter bars 11, a cutter bar 33 is positioned below the waste paper bale before it moves into it in order to cut the binding wires on the spikes 32 serving as abutments. The penetration depth should be about 50 mm in each case in order to reliably detect even deeply inserted wires.

Vor Beginn des Arbeitshubes müssen die Messerbalken 11 und 12 bzw. 33 nicht völlig unterhalb bzw. oberhalb des Altpapierbal­lens positioniert werden, ehe sie in denselben hineinfahren. In diesem Falle müßte nämlich das Plattenförderband B für die Ballen A relativ schmal sein, so daß die Ballen mit ihren Längskanten über dem Ballenförderer überstehen. Es genügt auch, wenn die Messerbalken so positioniert werden, daß sie unterhalb des untersten bzw. oberhalb des obersten Bindedrahts in den Ballen hineingedrückt werden, um erst dann den Arbeitshub (z.B. Schneidhub) zu beginnen. Dies ist ohne weiteres möglich, da die Altpapierballen relativ lose gepreßt sind, so daß sie einem Eindringen der Messerbalken in den Ballen einen nicht so großen Widerstand entgegensetzen.Before the start of the working stroke, the cutter bars 11 and 12 or 33 do not have to be positioned completely below or above the waste paper bale before they move into the same. In this case, the plate conveyor belt B for the bales A would have to be relatively narrow, so that the bales protrude with their longitudinal edges above the bale conveyor. It is also sufficient if the cutter bars are positioned in such a way that they are pressed into the bale below the lowest or above the uppermost binding wire, only to begin the working stroke (eg cutting stroke). This is easily possible since the waste paper bales are pressed relatively loosely, so that they do not offer as great resistance to penetration of the cutter bars in the bales.

In Fig. 3 ist eine doppeltwirkende Hydraulik-Kolben-Zylin­der-Einheit dargestellt, wobei zwei Kolben 36 und 37 Kolben­stangen 26′ bzw. 39 betätigen, an denen Messerbalken 11 bzw. 11′ befestigt sind. Dann laufen ohne weiteres die Messerbalken 11 und 11′ zueinander fluchtend und in dem Längsschlitz 41 des Trägers 2.In Fig. 3, a double-acting hydraulic piston-cylinder unit is shown, two pistons 36 and 37 actuating piston rods 26 'and 39, on which cutter bars 11 and 11' are attached. Then the cutter bars 11 and 11 'run in alignment with one another and in the longitudinal slot 41 of the carrier 2.

Es ist jedoch ohne weiteres möglich, je eine einfach wirkende Hydraulik-Kolben-Zylinder-Einheit für jeden Messerbalken 11 bzw. 11′ zu verwenden, die nebeneinander auf der Trägereinheit 2′ befestigt sind. Dann müssen entweder die Enden der Kolben­stange oder die Messerbalken jeweils abgekröpft ausgebildet werden.However, it is easily possible to use a single-acting hydraulic piston-cylinder unit for each cutter bar 11 or 11 ', which are attached next to each other on the carrier unit 2'. Then either the ends of the piston rod or the cutter bars must each be cranked.
