Abstract

According to the invention, a fibre bale stripper 1.1, which travels in the direction of arrow A with the bale stripper element 30 over a row of bales 4 and, by means of the stripper rolls 6a and 6b, detaches fibre tufts from the surface of the bale rows, is operated with the stripper rolls set at an angle in order either to increase the productivity or, for the same productivity, reduce the tuft size. The stripper rolls 6a and 6b are set at an angle according to the invention in such a way that the penetration depth T.1 corresponds essentially to half the penetration depth T.2. These penetration depths can be achieved on the one hand by adjusting the position of the stripper element 30 in the direction D, specifically to achieve the stripping depth T.1, and on the other through the pivotability of the stripper element 30 about the pivot axis 33. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zum Abtragen von Faserflocken aus in Rei­he angeordneten Faserballen, z.B. Baumwoll- oder Kunstfaserballen und dergleichen, mittels einem über die Faserballen fahrenden Abtragorgan mit mindestens 2 rotierenden Abtragwalzen gemäss dem Oberbegriff des 1. Verfahrens- und 1. Vorrichtungsanspruches.The invention relates to a method and an apparatus for removing fiber flakes from fiber bales arranged in series, e.g. Cotton or synthetic fiber bales and the like, by means of a removal member traveling over the fiber bales with at least 2 rotating removal rollers according to the preamble of the 1st method and 1st device claim.

Aus der deutschen Patentschrift DE-3334222 C2 ist eine Vorrichtung mit einem Abtragorgan zum Abtragen von Faserballen mit zwei rotierenden Abtragwalzen be­kannt, bei welcher für das Abtragen der Faserflocken das Abtragorgan über die Faserballenoberfläche hin und her gefahren wird und bei jeder Überfahrt mit ei­ ner vorgegebenen Eindringtiefe in die Faserballen ein­dringt, um den Abtragwalzen Gelegenheit zu geben, Fa­serflocken aus der Oberfläche zu lösen, welche an­schliessend einem pneumatischen Förderschacht über­geben werden.From the German patent DE-3334222 C2 a device with a removal member for removing fiber bales with two rotating removal rollers is known, in which the removal member is moved back and forth over the fiber bale surface for the removal of the fiber flakes and with each crossing with egg a predetermined penetration depth penetrates into the fiber bales in order to give the removal rollers the opportunity to detach fiber flakes from the surface, which are then transferred to a pneumatic conveyor shaft.

Aus der Praxis ist es bekannt, dass bei solchen Doppelwalzen-Ballenöffner die Abtragwalzen gegenläu­fig drehen, wobei jeweils die in Fahrtrichtung gese­hen vordere Abtragwalze im sogenannten Gleichlauf mit der Fahrtrichtung dreht, um die Faserflocken in die­sem Gleichlauf aus der Oberfläche zu lösen. Die in Fahrtrichtung gesehen hintere Walze dreht entspre­chend in entgegengesetzter Drehrichtung und löst im Gegenlauffrässystem Faserflocken aus derselben Ober­fläche.It is known from practice that in such double roller bale openers the removal rollers rotate in opposite directions, the front removal roller viewed in the direction of travel rotating in the so-called synchronism with the direction of travel in order to detach the fiber flakes from the surface in this synchronization. The rear roller seen in the direction of travel rotates in the opposite direction and loosens fiber flakes from the same surface in the counter-milling system.

Es ist nun jedoch bekannt, dass das Faserflocken-He­rauslösen in der vorgenannten Gegenlaufrichtung einen schlechteren mengenmässigen Auflösewirkungsgrad auf­weist als eine Walze, welche in Gleichlaufrichtung dreht.However, it is now known that the removal of fiber flakes in the aforementioned counter-direction has a poorer quantitative degree of dissolution efficiency than a roller which rotates in the direction of rotation.

Ebenfalls sind Abtragorgane mit einer Auflösewalze bekannt, deren Drehrichtung reversierbar ist, sodass die Auflösewalze jeweils in Gleichlaufrichtung dreh­bar ist.Removal elements with an opening roller are also known, the direction of rotation of which can be reversed, so that the opening roller can be rotated in the direction of synchronization.

Mit der vorgenannten Doppelwalzenanordnung des Stan­ des der Technik besteht zwar die Möglichkeit, im Hin-­und Hergang des Abtragorganes Flocken auszulösen, ohne die Abtragwalzen in ihrer Drehrichtung ändern zu müssen, weil jeweils die in Fahrtrichtung gesehen vor­dere Walze in Gleichlaufrichtung dreht. Eine Erhöhung der Abtragleistung kann im Vergleich mit dem genann­ten Einwalzen-Abtragorgan jedoch infolge des schlech­ten mengenmässigen Wirkungsgrades der gegenläufigen Abtragwalze kaum erreicht werden.With the aforementioned double roller arrangement of the Stan of the technology there is the possibility of triggering flakes in the back and forth of the removal member without having to change the removal rollers in their direction of rotation, because the front roller viewed in the direction of travel rotates in the direction of rotation. However, an increase in the removal rate can hardly be achieved in comparison with the single-roll removal member mentioned due to the poor quantitative efficiency of the opposing removal roller.

Eine Verbesserung der vorgenannten Abtragleistung be­steht in der Möglichkeit, beide Abtragwalzen pro Fahrtrichtung in Gleichlaufrichtung drehen zu lassen, was jedoch bedingt, dass für die Rückfahrt den Walzen eine entgegengesetzte Drehrichtung gegeben wird oder, dass das Abtragorgan von der Oberfläche abgehoben wird, so dass Faserflocken nur in einer Fahrtrichtung ausgelöst werden können. Die Leistungserhöhung ist jedoch im letztgenannten Falle selbst mit einer raschen Rückfahrt etwas problematisch, da je nach Länge der Ballenreihen ein Zeitinterval in Kauf ge­nommen werden muss, während welchem keine Faserflok­ken herausgelöst werden.An improvement of the abovementioned removal performance consists in the possibility of having both removal rollers turn in the same direction in each direction of travel, which however requires that the rollers are given an opposite direction of rotation for the return trip or that the removal member is lifted from the surface, so that fiber flakes only can be triggered in one direction. In the latter case, however, the increase in output is somewhat problematic even with a quick return trip, since, depending on the length of the bale rows, a time interval must be accepted during which no fiber flakes are released.

Ein weiteres Mittel, um die Leistung zu erhöhen, be­steht bekannterweise darin, die Walzenlänge entspre­chend zu vergrössern, und zwar mit Abtragorganen, welche eine einzige Walze oder zwei Walzen aufweisen.Another means of increasing the performance is known to be to increase the length of the roll accordingly, with removal elements which have a single roll or two rolls.

Der Nachteil einer solchen Massnahme besteht jedoch in der weiten Ausladung des Abtragorganes am fahrba­ren, das Abtragorgan aufnehmenden Ständer, was eine mechanisch höhere Belastung des ganzen Systems er­gibt.The disadvantage of such a measure, however, consists in the wide radius of the removal member on the mobile stand receiving the removal member, which results in a mechanically higher load on the entire system.

Es ist deshalb Aufgabe der Erfindung, die Abtraglei­stung, ohne Abhängigkeit der Länge der Abtragewalzen zu erhöhen.It is therefore an object of the invention to increase the removal rate without depending on the length of the removal rollers.

Die Lösung der Aufgabe besteht verfahrensmässig da­rin, dass die Eindringtiefe der Walzen in bezug auf die abzutragende Oberfläche der Ballen unterschied­lich ist und vorrichtungsmässig, dass die Walzen lageverstellbar angeordnet sind.In terms of the method, the solution to the problem is that the depth of penetration of the rollers is different with respect to the surface of the bale to be removed and, in terms of the device, that the rollers are arranged so that they can be adjusted.

Vorteilhafte Ausführungsformen sind in den entspre­chenden, abhängigen Ansprüchen aufgeführt.Advantageous embodiments are set out in the corresponding dependent claims.

Die Vorteile der Erfindung bestehen darin, dass einer­seits durch die unterschiedliche Eindringtiefe der Walzen beide Walzen die volle Abtragtiefe ausnützen können, so dass bei einer Zweiwalzen-Anordnung eine effektive Verdoppelung der Abtragleistung geschieht, oder dass andererseits bei einer für eine Walze äqui­valenten Abtragleistung kleinere Flocken herausgelöst werden können, da bekanntlich mit zunehmender Ein­dringtiefe pro Überfahrt die Flockengrösse vergrös­ sert wird, was nicht immer erwünscht ist. Anders aus­gedrückt, kann mit einer Doppel- oder Mehrfachwalzen- Anordnung eine gegenüber einer Einfachwalzen-Anord­nung, bei gleicher Eindringtiefe, Doppel- oder Mehr­fachleistung erbracht werden, oder es besteht die Mög­lichkeit, bei gegebener Leistung durch Verringerung der Eindringtiefe die Flockengrösse zu verringern.The advantages of the invention are that, on the one hand, due to the different penetration depth of the rollers, both rollers can utilize the full removal depth, so that the removal capacity is effectively doubled in a two-roller arrangement, or, on the other hand, smaller flakes are removed with an removal capacity equivalent to a roller can be, since the flake size increases with increasing depth of penetration per crossing what is not always desired. In other words, a double or multiple roller arrangement can be used to achieve a double or multiple output compared to a single roller arrangement with the same penetration depth, or there is the possibility of reducing the flake size by reducing the penetration depth for a given output.

Eine Vorrichtung 1 zum Abtragen von Faserflocken um­fasst einen Ständer 2, welcher mittels Räder 3 auf Schienen (nicht gezeigt) einer Ballenreihe 4 entlang fährt, und zwar in der in Fig. 1 gezeigten Richtung A und in der in Fig. 2 gezeigten Richtung B. Am Ständer 2 ist ein Abtragorgan 5 auf Führungsschienen (nicht gezeigt) auf und ab, entsprechend den Pfeilen C und D, bewegbar angeordnet.A device 1 for removing fiber flakes comprises a stand 2, which travels along rails (not shown) along a row of bales 4 by means of wheels 3, in the direction A shown in FIG. 1 and in the direction B shown in FIG. 2. On the stand 2, a removal member 5 is movably arranged up and down on guide rails (not shown) in accordance with the arrows C and D.

Das Abtragorgan 5 weist zwei rotierende Abtragwalzen 6a und 6b auf, welche bspw. aus der europäischen Pa­tentanmeldung 0058781 her bekannt sind. Aus dieser Patentanmeldung ist bekannt, dass diese Abtragwalzen aus einer Aneinanderreihung von Zahnscheiben mit Zwischenräumen zwischen den Scheiben bestehen und dass in den Zwischenräumen Roststäbe 7 vorgesehen sind, die entweder wie in Fig. 5 gezeigt bewegbar, oder wie in Fig. 6 gezeigt fest angeordnet sind. Die Befestigung der Roststäbe wird später noch erläutert.The removal member 5 has two rotating removal rollers 6a and 6b, which are known, for example, from European patent application 0058781. From this patent application it is known that these removal rollers are made up of a series of toothed disks There are gaps between the panes and that grate bars 7 are provided in the gaps, which are either movable as shown in FIG. 5 or fixedly arranged as shown in FIG. 6. The attachment of the grate bars will be explained later.

Die Abtragwalzen 6a und 6b sind je in einem Walzenträ­ger 8 resp. 9 dreh- und antreibbar gelagert.The removal rollers 6a and 6b are each in a roller carrier 8 and 9 rotatably and drivably mounted.

Diese Walzenträger 8 resp. 9 sind ihrerseits im Ab­tragorgan 5 mittels Gleitschienen (nicht gezeigt), gegemäss den Pfeilrichtungen E und F auf und ab beweg­bar geführt, wobei diese Bewegung mittels eines Stellenmotorantriebes 10 (Fig. 2) durchgeführt wird. Ein solcher Antrieb umfasst einen am Abtragorgan 5 mittels einer Konsole 11 (Fig. 1) befestigten Getrie­bemotor 12 mit einem Umdrehungsimpulsgeber 13. Die Ab­gangswelle des Getriebemotors ist gleichzeitig eine Spindel 14, welche in einer Spindelhülse 15 geführt ist. Die Spindelhülse ihrerseits ist am Walzenträger 8 resp. 9 befestigt. Die Walzenträger 8 resp. 9 um­fassen im weiteren je ein Leitblech 16 und 17 (Fig. 2), welche nach oben, mit Blick auf die Figuren gesehen, in einen Austrittskanal 18 münden. In diesen Austrittskanal greift ein Absaugkanal 19 resp. 20 mit einem minimalen Spiel zwischen dem jeweiligen Absaug­kanal und dem Austrittskanal 18 ein, um in der Umge­bung der Abtragwalzen den für die Absaugung der Faser­flockenförderluft notwendigen Unterdruck zu erzeugen.This roller carrier 8, respectively. 9 are in turn guided in the removal member 5 by means of slide rails (not shown), movable up and down in the direction of the arrows E and F, this movement being carried out by means of a servomotor drive 10 (FIG. 2). Such a drive comprises a geared motor 12 with a rotation pulse generator 13 attached to the removal member 5 by means of a bracket 11 (FIG. 1). The output shaft of the geared motor is at the same time a spindle 14 which is guided in a spindle sleeve 15. The spindle sleeve is in turn on the roller carrier 8, respectively. 9 attached. The roller carrier 8, respectively. 9 each further comprise a baffle plate 16 and 17 (FIG. 2), which open into an outlet channel 18 when viewed upward with a view of the figures. In this outlet channel, a suction channel 19 resp. 20 with a minimal play between the respective suction channel and the outlet channel 18 in order to generate the negative pressure necessary for the suction of the fiber flock conveying air in the vicinity of the removal rollers.

Die Austrittskanäle 18 sowie die Absaugkanäle 19 resp. 20 reichen mindestens über die gesamte Länge der Abtragwalzen 6a resp. 6b, d.h. überdecken diese Abtragwalzen.The outlet channels 18 and the suction channels 19, respectively. 20 extend at least over the entire length of the removal rollers 6a, respectively. 6b, i.e. cover these removal rollers.

Die Absaugkanäle 19 und 20 sind an ein Absaugrohr 21 angeschlossen, welches seinerseits an einer Unter­druckquelle (nicht gezeigt) angeschlossen ist, um den vorerwähnten Faserflockenförderluftstrom zu erzeugen. Das Absaugrohr ist dabei konisch gestaltet, und zwar derart, dass dieses zunehmend gegen den Unterdrucker­zeuger einen grösseren Durchmesser aufweist, um eine über die ganze Länge entsprechend der Abtragwalzen, im wesentlichen gleichmässig abgesaugte Luftmenge zu erhalten. Die Unterdruckquelle ist an sich aus der Praxis bekannt und wird deshalb nicht näher erläu­tert.
Als nicht gezeigte Variante könnte das Abtragorgan 5 derart abgeändert werden, dass nicht das ganze Abtrag­organ auf und ab bewegbar ist, sondern lediglich die Walzenträger 8 und 9. Dementsprechend müsste der Aus­trittskanal 18 und der Absaugkanal 19 resp. 20 teles­kopartig gestaltet sein, und die Spindel 14 müsste eine entsprechende Verlängerung erfahren. Das Abtrag­organ 5 als solches wäre in einer derartigen Variante stationär angeordnet.The suction channels 19 and 20 are connected to a suction pipe 21, which in turn is connected to a vacuum source (not shown) in order to generate the aforementioned fiber flock conveying air flow. The suction pipe is designed conically in such a way that it increasingly has a larger diameter against the vacuum generator in order to obtain an essentially uniform amount of air sucked off over the entire length corresponding to the removal rolls. The vacuum source is known per se from practice and is therefore not explained in more detail.
As a variant, not shown, the removal member 5 could be modified such that not the entire removal member can be moved up and down, but only the roller carriers 8 and 9. Accordingly, the outlet channel 18 and the suction channel 19 or. 20 should be designed telescopically, and the spindle 14 would have to undergo a corresponding extension. The removal member 5 as such would be arranged stationary in such a variant.

Die Roststäbe 7 sind auch im Falle der letztgenannten Variante ein Bestandteil des Walzenträgers 8 resp. 9, wobei diese Roststäbe, wie in Fig. 5 gezeigt, oder wie in Fig. 6 gezeigt, befestigbar sind.The grate bars 7 are also a component of the roller carrier 8 or in the case of the latter variant. 9, these grate bars, as shown in FIG. 5 or as shown in FIG. 6, can be fastened.

Die Figuren 3,4,6 und 7 zeigen eine erfindungsgemässe Variante, in welcher die gleichen Elemente der Figu­ren 1 und 2 die selben Bezugszeichen aufweisen. Diese Variante zeigt eine Vorrichtung 1.1 zum Abtragen von Faserflocken mit dem Ständer 2, jedoch mit einem Ab­tragorgan 30, in welchem die dreh- und antreibbaren Abtragwalzen 6a resp. 6b in Bezug auf das Abtragorgan stationär angeordnet sind.FIGS. 3, 4, 6 and 7 show a variant according to the invention, in which the same elements of FIGS. 1 and 2 have the same reference symbols. This variant shows a device 1.1 for removing fiber flakes with the stand 2, but with a removal member 30, in which the rotatable and driven removal rollers 6a, respectively. 6b are arranged stationary with respect to the removal member.

Das Abtragorgan 30 ist als Ganzes mittels einer hohlen Schwenkachse 31, welche um eine Drehachse 39 dreht, schwenkbar gelagert. Dabei wird die Schwenk­achse 31 von einem, in einem Gleitschlitten 40 vorge­sehenen Drehlager 40 (Fig. 7) aufgenommen. Die Mittel, um den Gleitschlitten 40 auf und ab zu bewe­gen, sind in der EP-Anmeldung Nr. 193647 beschrieben.The removal member 30 is pivotally mounted as a whole by means of a hollow pivot axis 31 which rotates about an axis of rotation 39. The pivot axis 31 is received by a rotary bearing 40 (FIG. 7) provided in a sliding carriage 40. The means for moving the slide 40 up and down are described in EP application no. 193647.

Im weiteren sind Roststäbe 32 entweder in der mit Fig. 5 oder in der mit Fig. 6 gezeigten Weise befestigt.Furthermore, grate bars 32 are fastened either in the manner shown in FIG. 5 or in the manner shown in FIG. 6.

Das Schwenken des Abtragorganes 30 um die Drehachse 39 geschieht mittels eines Stellmotorantriebes 33 (Fig. 6). Dieser umfasst einen Getriebemotor 34, der schwenkbar an einem mit dem Abtragorgan, entsprechend den Bewegungsrichtungen C und D, auf und ab bewegba­ ren Gleitelement 35 befestigt ist. Dieses ist durch ein stationär angeordnetes Führungsrohr 41 geführt. Dabei wird das Gleitelement 35 für die Bewegungen in den vorgenannten Richtungen durch einen Mitnehmer 42 mitgenommen, welcher einerseits am Gleitelement 35 und andererseits am Gleitschlitten 40 fest angeordnet ist. Im weiteren ist die Ausgangswelle des Getriebemo­tors als Spindel 36 vorgesehen, welche in einer Spin­delhülse 37 geführt ist. Die Spindelhülse ihrerseits ist wiederum schwenkbar am Abtragorgan 30 mittels eines Schwenklagers 38 befestigt.The removal member 30 is pivoted about the axis of rotation 39 by means of an actuator drive 33 (FIG. 6). This comprises a geared motor 34 which can be pivoted up and down on the removal member in accordance with the directions of movement C and D ren sliding member 35 is attached. This is guided through a stationary guide tube 41. The sliding element 35 is carried along for the movements in the aforementioned directions by a driver 42, which is fixedly arranged on the one hand on the sliding element 35 and on the other hand on the sliding carriage 40. Furthermore, the output shaft of the geared motor is provided as a spindle 36, which is guided in a spindle sleeve 37. The spindle sleeve is in turn pivotally attached to the removal member 30 by means of a pivot bearing 38.

Im weiteren umfasst das Abtragorgan 30 für das Führen der Faserflocken fordernden Luftstromes noch einen Luftführungsschacht, welcher sich entsprechend seinen Funktionen über mindestens die ganze Länge der Abtrag­walzen 6a resp. 6b erstreckt und mit einem Absaugrohr verbunden ist, welches zur Erzeugung des genannten Luftstromes seinerseits an einer Unterdruckquelle (nicht gezeigt) angeschlossen ist.Furthermore, the removal member 30 for guiding the air flow demanding fiber flakes also includes an air duct, which according to its functions extends over at least the entire length of the removal rollers 6a and 6a. 6b extends and is connected to a suction pipe which, in turn, is connected to a vacuum source (not shown) in order to generate the air flow mentioned.

Als Variante dazu zeigt die Fig. 5 eine weitere Ausge­staltung der mit der europäischen Patentanmeldung No. 0199041 gezeigten Ausführungsform, welche eine Be­schreibung der Bewegung der Roststäbe enthält, sodass im Zusammenhang mit Fig. 5 lediglich die wesentlichen Merkmale, jedoch mit neuen Kennzeichen wiederholt wer­den. Im weiteren sind dieselben Elemente der Fig. 6 mit denselben Bezugszeichen versehen.As a variant, FIG. 5 shows a further embodiment of the European patent application no. Embodiment shown 0199041, which contains a description of the movement of the grate bars, so that in connection with FIG. 5 only the essential features are repeated, but with new characteristics. Furthermore, the same elements in FIG. 6 are provided with the same reference symbols.

Aus der europäischen Patentanmeldung 0199041 sind be­reits verstellbare Roststäbe, welche relativ zur Lage der Abtragwalzen bewegbar sind, bekannt, weshalb die mit Fig. 5 gezeigte Variante nicht in allen Details erklärt wird.From the European patent application 0199041 adjustable grate bars, which are movable relative to the position of the removal rollers, are already known, which is why the variant shown in FIG. 5 is not explained in all details.

Die in Fig. 5 gezeigten Roststäbe 32.1 sind an Längs­trägern 50 befestigt, die ihrerseits mittels einem schwenkbar daran befestigten Hubmechanismus relativ zu den Abtragwalzen 6a resp. 6b bewegbar sind. Der Hubmechanismus umfasst die in der vorgenannten euro­päischen Patentanmeldung gezeigten Getriebestoppmoto­ren 51 sowie die Gewindespindeln 52.The grate bars 32.1 shown in Fig. 5 are attached to side members 50, which in turn by means of a pivotally attached lifting mechanism relative to the removal rollers 6a and. 6b are movable. The lifting mechanism comprises the gear stop motors 51 shown in the aforementioned European patent application and the threaded spindles 52.

Die Spindeln 52 sind in Spindelhülsen 53 geführt, wel­che schwenkbar mit den Längsträgern 50 verbunden sind. Wie im weiteren aus der europäischen Patentan­meldung 0199041 ersichtlich, sind pro Längsträger 50 zwei Hubvorrichtungen vorgesehen. Dementsprechend sind die Getriebestoppmotoren mit Umdrehungsimpuls­gebern 54 ausgerüstet, womit in einer Steuerung (nicht gezeigt) die Lage der Abtragroste 32.1 vorge­geben werden kann. Solche Steuerungen sind an sich bekannt.The spindles 52 are guided in spindle sleeves 53 which are pivotally connected to the longitudinal beams 50. As can be seen further from European patent application 0199041, two lifting devices are provided for each longitudinal beam 50. Accordingly, the gear stop motors are equipped with rotation pulse generators 54, with which the position of the removal grates 32.1 can be specified in a controller (not shown). Such controls are known per se.

Im weiteren sei nochmals erwähnt, dass das Abtragor­gan 30.1 der Fig. 5 in gleicher Weise mit einem in Fig. 6 gezeigten Schwenkmechanismus versehen werden kann und in gleicher Weise um die Drehachse 39 schwenkbar sein kann, ohne dies nochmals im Detail zu erwähnen.It should also be mentioned again that the removal member 30.1 of FIG. 5 is provided in the same way with a swivel mechanism shown in FIG. 6 can and can be pivoted in the same way about the axis of rotation 39 without mentioning this again in detail.

Mit den Figuren 7 bis 10 sind verschiedene Betriebs­varianten gezeigt, welche mit den bisher gezeigten Vorrichtungen ausgeführt werden können.FIGS. 7 to 10 show various operating variants which can be carried out using the devices shown hitherto.

Dabei zeigt Fig. 8 die Verwendungsmöglichkeit des Ab­tragorganes 30 (Fig. 6) und 30.1 (Fig. 5).8 shows the possible uses of the removal member 30 (FIG. 6) and 30.1 (FIG. 5).

Im Falle der Verwendung des Abtragorganes 30 weist der sich aus der Schwenkung dieses Abtragorganes erge­bende Schwenkwinkel α. 1 der Abtragwalzen 6a und 6b die gleiche Grösse auf wie der Schwenkwinkel β.1 der Roststäbe 32. Dabei wird einerseits der Winkel α.1 von einer gedachten Ebene 56, welche am Umfang der Ab­tragwalzen 6a und 6b anliegt, und andererseits der Winkelβ.1 von der Ebene 55 und einer gedachten Ebene 57 gebildet, welche die untere,in die Ballenoberflä­che eintauchende Fläche der Roststäbe beinhaltet. Der Schwenkwinkelα .1 wird in der Regel derart gewählt, dass die Eindringtiefe T.1 der Abtragwalze 6a etwa halb so gross ist wie die Eindringtiefe T.2 der Ab­tragwalze 6b. Dabei wird unter Eindringungstiefe das Mass des Eindringens der jeweiligen Abtragwalze gegen­über der Ballenoberfläche vor dem Abtragorgan 30 verstanden. Dies gilt, ob der Ständer in Richtung A (Fig. 3) oder in Richtung B fährt. Ausserdem ist bei der Verwendung des Abtragorgans 30 der Winkel α gleich dem Winkel β .If the removal member 30 is used, the pivoting angle α resulting from the pivoting of this removal member has. 1 of the removal rollers 6a and 6b has the same size as the pivoting angle β.1 of the grate bars 32. On the one hand, the angle α.1 of an imaginary plane 56, which lies on the circumference of the removal rollers 6a and 6b, and on the other hand the angle β.1 formed by the plane 55 and an imaginary plane 57, which contains the lower surface of the grate bars which dips into the bale surface. The swivel angle α .1 is generally chosen such that the depth of penetration T.1 of the removal roller 6a is approximately half the depth of penetration T.2 of the removal roller 6b. The penetration depth is understood to mean the degree of penetration of the respective removal roller relative to the bale surface in front of the removal member 30. This applies whether the stand moves in direction A (Fig. 3) or in direction B. In addition, the use of the removal member 30, the angle α is equal to the angle β.

Die Fig. 9 zeigt dasselbe, jedoch für die Fahrtrich­tung B. Es gilt deshalb das für die Winkel α.1 und β.1 Gesagte auch für die Winkel α.2 resp. β.2.Fig. 9 shows the same, but for the direction of travel B. Therefore, what has been said for the angles α.1 and β.1 also applies to the angles α.2 and. β.2.

Wird in einer ebenfalls möglichen Variante die Auf­hängung der Roststäbe 32.1 der Fig. 5 mit einem schwenkbaren Abtragorgan, gemäss dem Abtragorgan 30 der Fig. 6 kombiniert, so besteht die Möglichkeit, die Winkel α.1 resp. α.2 und β.1 resp. β.2 (Fig. 8) un­terschiedlich zu wählen.If, in a variant which is also possible, the suspension of the grate bars 32.1 of FIG. 5 is combined with a pivotable removal member, according to the removal member 30 of FIG. 6, it is possible to adjust the angles α.1 or. α.2 and β.1 respectively β.2 (Fig. 8) to choose differently.

Mit den Drehrichtungspfeilen G (Fig. 8) resp. H (Fig. 9) wird gezeigt, dass im Falle von Fig. 8 die Abtragwalzen mit der Drehrichtung G resp. in Fig. 9 mit der Drehrichtung H sogenannt gleichlaufend mit der Fahrtrichtung A resp. B drehen. Hingegen, wenn die Abtragwalzen 6a und 6b entsprechend den Drehrich­tungen K und L drehen, dreht im Falle von Fig. 8, die Abtragwalze 6a gleichlaufend und die Abtragwalze 6b gegenlaufend, während im Beispiel von Fig. 9 die Abtragwalze 6b gleichlaufend und die Abtragwalze 6a gegenlaufend dreht. Die Fig. 10 zeigt ein Beispiel mit der Anwendung des Abtragorganes 30.1, d.h. ohne Schwenkmechanismus, d.h. lediglich mit einer Verstell­möglichkeit der Roststäbe 32.1, so dass der Unter­ schied der Eindringtiefe T.3 zwischen der Abtragwalze 6a und der Abtragwalze 6b durch das Einstellen der Roststäbe 32.1 mit dem Winkel β.3 für die Fahrtrich­tung A und mit dem Winkel β .4 für die Fahrtrichtung B erzeugt wird. Dabei können die Drehrichtungen G und H oder K und L gewählt werden.With the direction arrows G (Fig. 8) respectively. H (Fig. 9) shows that in the case of Fig. 8 the removal rollers with the direction of rotation G or. in Fig. 9 with the direction of rotation H so-called synchronized with the direction of travel A respectively. B turn. On the other hand, if the removal rollers 6a and 6b rotate according to the directions of rotation K and L, in the case of FIG. 8, the removal roller 6a rotates in the same direction and the removal roller 6b in the opposite direction, while in the example of FIG. 9 the removal roller 6b rotates in the same direction and the removal roller 6a in the opposite direction turns. 10 shows an example with the use of the removal member 30.1, ie without a swivel mechanism, ie only with an adjustment possibility of the grate bars 32.1, so that the lower the penetration depth T.3 between the removal roller 6a and the removal roller 6b is produced by adjusting the grate bars 32.1 with the angle β.3 for the direction of travel A and with the angle β .4 for the direction of travel B. The directions of rotation G and H or K and L can be selected.

Die Fig. 11 zeigt die Verwendung des Abtragorganes 5 gemäss den Figuren 1 und 2, jedoch lediglich für die Fahrtrichtung A. Die Eindringtiefen T.1 und T.2 sind individuell anwählbar und können entsprechend in der Rückfahrt B (nicht in Fig. 10 dargestellt) wechselsei­tig erfolgen, sofern in beiden Fahrtrichtungen Flok­ken abgetragen werden.11 shows the use of the removal member 5 according to FIGS. 1 and 2, but only for the direction of travel A. The penetration depths T.1 and T.2 can be selected individually and can be correspondingly shown in the return trip B (not shown in FIG. 10) ) take place alternately, provided flakes are removed in both directions of travel.

Der mit doppelt gestrichelten Linien gezeigte Pfeil B und die mit gestrichelten Linien gezeigte Ballenreihe 4 deuten auf eine Variante hin, welche mit allen Ab­tragorganen möglich ist, nämlich, dass auf der Rück­fahrt die Abtragorgane 5 resp. 30 resp. 30.1 von der Ballenoberfläche weggehoben werden und immer dieselbe Schrägstellung aufweisen. Auf diese Weise werden immer nur in Richtung A Faserflocken aus den Ballen abgetragen. Diese Variante kann auch dann zum Tragen kommen, wenn beabsichtigt wird, die Mischung inner­halb der Faserballenreihe immer von der gleichen Sei­te her abzutragen. Für eine solche Variante kann auch eine feste Schräglage der Abtragwalzen gewählt wer­den.The arrow B shown with double dashed lines and the bale row 4 shown with dashed lines indicate a variant which is possible with all removal devices, namely that the removal devices 5 and. 30 resp. 30.1 are lifted away from the bale surface and always have the same inclination. In this way, fiber flakes are always removed from the bales only in direction A. This variant can also be used if it is intended to always remove the mixture from the same side within the row of fiber bales. A fixed inclined position of the removal rollers can also be selected for such a variant.

Im weiteren kann der in dieser Anmeldung dargelegte Erfindungsgedanke noch mit dem in der europäischen Patentanmeldung No. 0193647 gezeigten Erfindungsgedan­ken kombiniert werden. In der letztgenannten Anmel­dung wird dargestellt, dass die Zustelltiefe des Ab­tragorganes 5 resp. 30 resp. 30.1 pro Überfahrt mit zunehmender Faserballendichte verändert, d.h. verklei­nert wird, um erstens die Leistung gleichmässig zu ge­stalten und andererseits die Faserflocken schonend aus den Faserballen herauszulösen.Furthermore, the inventive idea set out in this application can still be compared with that in European patent application no. 0193647 inventive ideas can be combined. In the latter application it is shown that the depth of delivery of the removal member 5 or. 30 resp. 30.1 per passage changed with increasing fiber bale density, i.e. is reduced in size, firstly to make the output uniform and secondly to gently remove the fiber flakes from the fiber bales.

Das heisst, dass die Eindringtiefe T.1 resp. T.2 mit zunehmender Faserballendichte entsprechend ebenfalls verändert werden kann. Die dazu notwendige Vorrich­tung wird in der letztgenannten, europäischen Patent­anmeldung gezeigt und beschrieben, weshalb auf eine weitere Darstellung in dieser Anmeldung der Einfach­heit halber verzichtet wird.That means that the penetration depth T.1 resp. T.2 can also be changed accordingly with increasing fiber bale density. The device required for this is shown and described in the last-mentioned European patent application, which is why a further representation in this application is omitted for the sake of simplicity.

Letztlich versteht es sich von selbst, dass der Erfin­dungsgedanke und damit die gezeigten Ausführungsfor­men auch mit drei und mehr Abtragwalzen durchführbar ist, ebenso, dass Abtragorgane ohne Roststäbe verwen­det werden können.Ultimately, it goes without saying that the idea of the invention and thus the embodiments shown can also be carried out with three or more removal rollers, and also that removal elements can be used without grate bars.
