Abstract

The bale breaker, to remove the fibre contents from bales, has a swing axis for the extractor to pitch it at an angle to the horizontal while it is moved simultaneously to and fro and up and down.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Abtragen von Faserflocken aus aneinandergereihten Textilfaserballen mit einem den Faserballen entlang horizontal hin- und her- fahrbaren Maschinengestell und einem daran nach unten und aus seiner Endlage wieder nach oben bewegbaren Abtragorgan, an welchem eine horizontal und quer zur Fahrtrichtung gelagerte antreibbare Abtragwalze vorgesehen ist.The invention relates to a device for removing fiber flakes from lined-up textile fiber bales with a machine frame which can be moved horizontally back and forth along the fiber bale and a removal member which can be moved downwards and upwards from its end position, on which a horizontally and transversely to the direction of travel stored driven drivable roller is provided.

Aus der europäischen Patentanmeldung EP-A-193647 ist eine vorgenannte Vorrichtung bekannt. Das Erfinderische daran ist, dass die Abtragtiefe im Laufe des Abtragens entsprechend der Dichte der Faserballen verändert wird, um bei jeder Hin- und Herfahrt im wesentlichen dieselbe Leistung zu erhalten.A aforementioned device is known from European patent application EP-A-193647. The inventiveness of this is that the removal depth is changed in the course of the removal in accordance with the density of the fiber bales in order to obtain essentially the same performance with each return trip.

Es ist an sich bekannt, dass Faserballen, selbst wenn sie von den diese umgreifenden Stahlbändern befreit und in Reihe aufgestellt sind, nicht überall dieselbe Dichte aufweisen, d.h. dass beim Abtragen, ohne die vorgenannten erfinderischen Merkmale, sondern mit einer gleichbleibenden Abtragtiefe eine kleinere Drucksatzleistung erreicht wird als im mittleren Bereich der Faserballen-Höhe, in welcher die Dichte grösser ist.It is known per se that fiber bales, even if they are freed from the steel strips encompassing them and placed in a row, do not have the same density everywhere, i.e. that when removing, without the above-mentioned inventive features, but with a constant removal depth, a lower pressure output is achieved than in the central region of the fiber bale height, in which the density is greater.

Diesem Umstand wurde in einer anderen Vorrichtung nach der Schweizerischen Patentschrift Nr. 503809 bereits früher Rechnung getragen, da dort durch eine schräge Abtragart ein Durchschnitt, im wesentlichen aller Faserballendichten, in einer Überfahrt des Faserballenabtragorganes erreicht werden kann.This fact was taken into account earlier in another device according to the Swiss patent specification No. 503809, since an average of essentially all fiber bale densities can be achieved in one pass of the fiber bale removal member by an oblique type of removal.

In der letztgenannten Patentschrift ist es jedoch die Vorrichtung selbst, welche auf entsprechend schräg gestellten Schienen mit einem vorgegebenen Anstellwinkel diese Schrägfahrt durchführt. Der Vorschub für die Bestimmung der Abtragtiefe pro Hin- und Herfahrt des Abtragorganes wird mittels eines Förderbandes erzeugt, welches nach jeder Überfahrt des Abtragorganes um einen vorgegebenen Schritt in Richtung Ballenabtragorgan bewegt wird.In the last-mentioned patent specification, however, it is the device itself which carries out this inclined travel on correspondingly inclined rails with a predetermined angle of attack. The feed rate for determining the removal depth per return travel of the removal member is generated by means of a conveyor belt which is moved by a predetermined step in the direction of the bale removal member after each passage of the removal member.

Der Nachteil dieser Vorrichtung besteht im Mangel an Flexibilität, indem das Abtragorgan jeweils nur in einer vorbestimmten Lage über die Ballen bewegt werden kann.The disadvantage of this device is the lack of flexibility in that the removal member can only be moved over the bale in a predetermined position.

Derselbe Nachteil gilt auch für die mit der vorgenannten europäischen Patentanmeldung EP-A-193647 gezeigten Vorrichtung.The same disadvantage also applies to the device shown with the aforementioned European patent application EP-A-193647.

Diese Nachteile zu beheben ist Aufgabe der Erfindung, welche dadurch gelöst wird, dass das Abtragorgan um eine parallel zur Abtragwalze verlaufende Schwenkachse derart schwenkbar ist, dass die untere Abtragfläche des Abtragorganes in eine vorgegebene, von der Horizontalen abweichende Schräglage bringbar ist und dass, falls das Abtragorgan diese Schräglage einnimmt, dieses während des Hin- und Herfahrens des Maschinengestells sowohl nach unten als auch nach oben bewegbar ist, in der Weise, dass das Abtragen in einer ansteigenden bzw. abfallenden Ebene erfolgt.To solve these disadvantages is the object of the invention, which is achieved in that the removal member by a parallel pivot axis extending to the removal roller is pivotable in such a way that the lower removal surface of the removal member can be brought into a predetermined inclined position deviating from the horizontal and that if the removal member adopts this inclined position, it moves downward and downward as the machine frame moves back and forth is movable at the top in such a way that the removal takes place in a rising or falling plane.

Durch diese Fassung des Anspruchs 1 soll zum Ausdruck gebracht werden, dass nur dann, wenn die untere Abtragfläche in eine von der Horizontalen abweichende Schräglage gebracht wurde, durch das zusammenwirken von hin- und herfahrendem Maschinengestell und nach unten und nach oben bewegbarem Abtragsorgan das Abtragen der Faserballen in einer ansteigenden bzw. abfallenden Ebene erfolgen soll. Darüber hinaus ist aber auch die Möglichkeit vorgesehen, dass die untere Abtragfläche des an einer Schwenkachse schwenkbaren Abtragorgans in der Horizontalen verbleibt oder in diese geschwenkt wird, um ein Abtragen der Faserballen in horizontaler Richtung vorzunehmen.This version of claim 1 is intended to express that only when the lower removal surface has been brought into an inclined position that deviates from the horizontal, by the interaction of the reciprocating machine frame and the removal member that can be moved down and up, the removal of the Fiber bales should take place in an ascending or descending plane. In addition, however, the possibility is also provided that the lower removal surface of the removal member, which can be pivoted on a pivot axis, remains horizontal or is pivoted into it in order to remove the fiber bales in the horizontal direction.

Der Vorteil der Erfindung besteht deshalb darin, dass mit einer einzigen Vorrichtung die Möglichkeit besteht, Faserballen in rein horizontaler Richtung und(oder in Schrägrichtung abzutragen. Dies erlaubt, wie später erwähnt wird, die Abtragvorrichtung vielseitiger zu verwenden.The advantage of the invention is therefore that with a single device it is possible to remove fiber bales in a purely horizontal direction and (or in an oblique direction. This, as will be mentioned later, allows the removal device to be used in a more versatile manner.

Die vorteilhaften Ausführungsformen der Erfindung sind in den weiteren Ansprüchen aufgeführt.The advantageous embodiments of the invention are set out in the further claims.

Die Erfindung wird im folgenden anhand von lediglich Ausführungswege darstellenden Zeichnungen näher erläutert.The invention is explained in more detail below with the aid of drawings which only show execution routes.

Eine Vorrichtung 1 zum Abtragen von Faserflocken umfasst ein Abtragorgan 2, ein Maschinengestell 3 und einen Flockentransport 4.A device 1 for removing fiber flakes comprises a removal member 2, a machine frame 3 and a flake transport 4.

Das Abtragorgan 2 selbst umfasst eine Gehäusekonstruktion 5, in welcher eine rotierende Abtragwalze 6 antreibbar gelagert ist. Durch diese Gehäusekonstruktion 5 werden im weiteren die durch die Abtragwalze 6 von den Faserballen 7 abgetragenen Faserflocken aufgenommen und über nicht gezeigte Wege weiter in den Flockentransport 4 gefördert.The removal member 2 itself comprises a housing construction 5, in which a rotating removal roller 6 is drivably mounted. Through this housing construction 5, the fiber flakes removed by the removal roller 6 from the fiber bales 7 are received and further promoted into the flake transport 4 via paths not shown.

Die Gehäusekonstruktion 5 ist mittels drehbar daran befestigter und in Führungsschienen 8 des Maschinengestells 3 geführter Rollen 9 in Pfeilrichtung A auf- und abbewegbar. In Fig. 1 ist jedoch nur das eine Rollenpaar und nur die eine Schiene 8 gezeigt; die auf der Gegenseite in der gleichen Art vorgesehenen Rollen und vorgesehene Schiene sind nicht sichtbar.The housing construction 5 can be moved up and down in the direction of the arrow A by means of rollers 9 rotatably fastened to it and guided in guide rails 8 of the machine frame 3. In Fig. 1, however, only one pair of rollers and only one rail 8 is shown; the rollers and rails provided on the opposite side in the same way are not visible.

Im weiteren weist die Gehäusekonstruktion 5 einen Mitnehmer 10 auf, welcher mit einer Kette 11 eines Kettentriebes 12 fest verbunden ist.Furthermore, the housing construction 5 has a driver 10 which is firmly connected to a chain 11 of a chain drive 12.

Der Kettentrieb 12 umfasst im weiteren ein oberes, drehbar gelagertes Kettenrad 13 für die Umlenkung der Kette 11 und ein unteres Kettenrad 14 für den Antrieb dieser Kette 11. Das untere Kettenrad 14 ist dabei drehfest auf einer Antriebswelle 15 eines Getriebes 16 aufgezogen. Als Leistungsquelle für das Getriebe dient ein damit verbundener Elektromotor 17, welcher als Stoppmotor ausgebildet ist.The chain drive 12 further comprises an upper, rotatably mounted sprocket 13 for deflecting the chain 11 and a lower sprocket 14 for driving this chain 11. The lower sprocket 14 is rotatably mounted on a drive shaft 15 of a transmission 16. An electric motor 17 connected thereto, which is designed as a stop motor, serves as the power source for the transmission.

Der Kettentrieb 12, das Getriebe 16 und der Elektromotor 17 werden als Ganzes als Hubvorrichtung bezeichnet. Auf dem oberen Wellenende 18, mit Blickrichtung auf die Figur gesehen, des Motors 17 ist ein Zahnrad 19 drehfest aufgesetzt, welches als Zählrad zusammen mit einem Initiator 20 als Impulsgeber funktioniert, dessen Impulse über eine Leitung 21 einem Mikroprozessor 22 zugeführt werden. Der Initiator 20 ist handelsüblich und gibt bei jedem vorbeigehenden Zahn des Zahnrades 19 einen Impuls ab. Der Initiator 20 ist ortsfest vorgesehen.The chain drive 12, the transmission 16 and the electric motor 17 are referred to as a whole as a lifting device. On the upper shaft end 18, as viewed in the direction of the figure, of the motor 17, a gear 19 is rotatably mounted, which together as a counting wheel works with an initiator 20 as a pulse generator, the pulses of which are fed via a line 21 to a microprocessor 22. The initiator 20 is commercially available and gives an impulse for each tooth of the gear 19 that passes. The initiator 20 is provided to be stationary.

Zur Abtastung der oberen und unteren Endposition des Abtragorganes ist am Maschinegestell 3 ein oberer Endschalter 23 und ein unterer Endschalter 24 vorgesehen.An upper limit switch 23 and a lower limit switch 24 are provided on the machine frame 3 for scanning the upper and lower end positions of the removal member.

Der obere Endschalter 23 wird von einer oberen Fläche 25 und der untere Endschalter 24 von einer unteren Fläche 26 des Mitnehmers 10 betätigt. Dabei gibt der obere Endschalter 23 seinen Impuls über eine Leitung 27 und der untere Endschalter 24 über eine Leitung 28 in den Mikroprozessor 22 ein.The upper limit switch 23 is actuated by an upper surface 25 and the lower limit switch 24 by a lower surface 26 of the driver 10. The upper limit switch 23 inputs its pulse via a line 27 and the lower limit switch 24 via a line 28 into the microprocessor 22.

Im weiteren ist an der gegen die Faserballen zugekehrten unteren Seite 29 der Gehäusekonstruktion 5 eine Lichtschranke mit einem Sender 30 und einem Empfänger 31 vorgesehen, welcher derart angeordnet ist, dass der Sender einen sich mindestens über die ganze Länge L der Abtragwalze 6 erstreckenden Lichtstrahls 32 erzeugt, der im Empfänger in ein über eine Leitung 33 dem Mikroprozessor 22 zugeführtes Signal umgewandelt wird.Furthermore, a light barrier with a transmitter 30 and a receiver 31 is provided on the lower side 29 of the housing construction 5 facing the fiber bale, which is arranged such that the transmitter generates a light beam 32 that extends at least over the entire length L of the removal roller 6 which is converted in the receiver into a signal supplied to the microprocessor 22 via a line 33.

Eine weitere Leitung 34 verbindet den Elektromotor 17 mit dem Mikroprozessor 22.Another line 34 connects the electric motor 17 to the microprocessor 22.

Im weiteren ist das Maschinengestell 3 mittels daran befestigter und antreibbarer Räder 35 auf Schienen 36, welche auf dem Spinnereiboden 37 befestigt sind, den Faserballen 7 entlang, in den Fahrtrichtungen K und M (Fig. 2) und über den Flockentransport 4 hinweg fahrbar angeordnet.Furthermore, the machine frame 3 is arranged by means of wheels 35 fastened to it and drivable on rails 36, which are fastened on the spinning floor 37, along the fiber bales 7, in the directions of travel K and M (FIG. 2) and over the flake transport 4.

Für den Antrieb eines Paares der Räder 35 (die Welle dieses Paares ist nicht gezeigt) ist im Maschinengestell im weiteren ein Stoppmotor 42 mit einem Getriebe 47 verbunden, welches über einen Übertrieb 48 das genannte Räderpaar 35 (Fig. 2) antreibt.For driving a pair of wheels 35 (the shaft of this pair is not shown), a stop motor 42 is further connected to a gear 47 in the machine frame, which drives said pair of wheels 35 (FIG. 2) via an overdrive 48.

An einem nach aussen gerichteten Wellenende des Stoppmotores ist ein Zahnrad 43 und am Stoppmotor selbst ein Initiator 44 vorgesehen. Der Initiator 44 ist über die Leitung 45 und der Elektromotor über die Leitung 46 mit dem Mikroprozessor 22 verbunden. Der Initiator dient, wie bereits früher für die Hubbewegung des Abtragorganes 5 erwähnt, dem Zählen der daran vorbeigehenden Zähne, um mittels des Mikroprozessors 22 die Lage der Vorrichtung zu erfassen.A gear 43 is provided on an outward shaft end of the stop motor and an initiator 44 on the stop motor itself. The initiator 44 is connected to the microprocessor 22 via the line 45 and the electric motor via the line 46. As already mentioned earlier for the lifting movement of the removal member 5, the initiator is used to count the teeth passing by in order to detect the position of the device by means of the microprocessor 22.

Ausserdem ist die Gehäusekonstruktion 5 in zwei Hauptteile unterteilt, nämlich einerseits in einen Gleitschlitten 49, an welchem der Mitnehmer 10 befestigt ist und einem Abtragwalzenträger 50, welcher mittels eines im Gleitschlitten vorgesehenen Schwenklagers 51 und der darin geführten und zum Abtragwalzenträger 50 gehörenden Schwenkachse 52 schwenkbar gelagert ist.In addition, the housing structure 5 is divided into two main parts, namely on the one hand in a sliding carriage 49, to which the driver 10 is attached and a removal roller carrier 50 which is pivotably mounted by means of a pivot bearing 51 provided in the sliding carriage and the pivot axis 52 guided therein and belonging to the removal roller carrier 50.

Um das Schwenken des Abtragwalzenträgers 50 durchzuführen, ist der Abtragwalzenträger im weiteren mittels einer Antriebsvorrichtung 53 mit einem Gleitschuh 54 verbunden, welcher auf einer stationär angeordneten Schiene 55 auf und ab, mit Blick auf Figur 2 gesehen, bewegbar ist. Der Gleitschuh seinerseits ist mittels eines Steges 56 mit dem Gleitschlitten 49 fest verbunden.In order to carry out the swiveling of the removal roller carrier 50, the removal roller carrier is further connected by means of a drive device 53 to a slide shoe 54, which can be moved up and down on a stationary rail 55, as seen in FIG. 2. The slide shoe in turn is fixedly connected to the slide carriage 49 by means of a web 56.

Die Antriebsvorrichtung 53 ihrerseits besteht aus einem Stellmotor 57, dessen Welle mit einem Gewinde 58 versehen ist, das in einer Gewindehülse 59 geführt ist. Dabei ist der Stellmotor 57 schwenkbar am Gleitschuh 54 und die Gewindehülse 59 schwenkbar an einem am Abtragwalzenträger 50 befestigten Schwenklager 60 vorgesehen.The drive device 53 in turn consists of an actuator 57, the shaft of which is provided with a thread 58 which is guided in a threaded sleeve 59. The servomotor 57 is pivotably provided on the sliding block 54 and the threaded sleeve 59 is pivotably provided on a pivot bearing 60 fastened to the removal roller carrier 50.

Unter Stellmotor soll ein Motor verstanden werden, welcher in der Lage ist, die Drehbewegung der Welle 58 genau zu erfassen und als Signal an den in Fig.1 gezeigten Mikroprozessor 22 zu übermitteln. Dadurch ist es möglich, den Abtragwalzenträger 50 mittels einer vorgewählten Anzahl Drehungen der Spindel 58 in eine vorgegebene Schräglage (in Fig. 3 und 4 gezeigt) zu bringen. In einer solchen Schräglage werden die in Reihe aufgestellten Faserballen 7, wie auf den Figuren 3 oder 4 gezeigt, abgetragen.A servomotor is to be understood as a motor which is able to precisely detect the rotary movement of the shaft 58 and to transmit it as a signal to the microprocessor 22 shown in FIG. This makes it possible to move the removal roller carrier 50 into a predetermined inclined position by means of a preselected number of rotations of the spindle 58 (shown in FIGS. 3 and 4). bring to. In such an inclined position, the fiber bales 7 set up in a row are removed, as shown in FIGS. 3 or 4.

Um dieses Abtragen zu realisieren, koordiniert der Mikroprozessor 22 die Signale der Leitungen 21 und 45 und steuert dementsprechend über die Leitungen 34 und 46 die Motoren 17 und 42.In order to realize this removal, the microprocessor 22 coordinates the signals of the lines 21 and 45 and accordingly controls the motors 17 and 42 via the lines 34 and 46.

Im wesentlichen ist eine in den Figuren 3 und 4 gezeigte Schrägabtragung zwischen den Abtragwinkeln α von 0° - 60° zu realisieren. Grössere Winkel α als 60° sind jedoch ebenfalls machbar. Andererseits ist es ebenfalls möglich, den Abtragwalzenträger 50 auf die gegenüberliegende Seite, von der Senkrechten her gesehen, zu schwenken, um dadurch eine Schräglage der unteren Abtragfläche des Abtragwalzenträgers mit dem Winkel α.1 (Fig. 3) zu erhalten. Daraus ist ersichtlich, dass mit der Abtragvorrichtung nicht nur in einer Richtung schräg abgetragen werden kann, sondern auch, wie in Fig. 3 gezeigt, in zwei einander gegenüberliegenden Schrägrichtungen.Essentially, an oblique removal between the removal angles α of 0 ° -60 ° shown in FIGS. 3 and 4 can be realized. However, angles α greater than 60 ° are also feasible. On the other hand, it is also possible to pivot the removal roller carrier 50 to the opposite side, as seen from the vertical, in order thereby to obtain an inclined position of the lower removal surface of the removal roller carrier with the angle α.1 (FIG. 3). It can be seen from this that the removal device can not only remove obliquely in one direction, but also, as shown in FIG. 3, in two opposite oblique directions.

Zur Positionierung des Maschinengestells in den Endlagen und in den Positionen jeweils zwischen einzelnen Ballengruppen, falls mehr als eine Ballengruppe in der mit Fig. 3 gezeigten Doppel-Schrägabtragung abgetragen werden soll, ist einerseits an der Maschinengestellunterseïte ein Initiator 38 und sind andererseits auf der ganzen Länge, auf welcher die Vorrichtung 1 fahrbar ist, sogenannte Positionierelemente 39 vorgesehen, welche auf einer Schiene 40 verschiebbar angeordnet sind. Das Vorhandensein dieser Positionierelemente 39 wird durch den Initiator 38 festgestellt und über eine Leitung 41 dem Mikroprozessor gemeldet.To position the machine frame in the end positions and in the positions between individual bale groups, if more than one bale group is to be removed in the double inclined removal shown in FIG. 3, on the one hand there is an initiator 38 on the lower side of the machine frame and on the other hand they are along the entire length on which the device 1 is movable, so-called positioning elements 39 are provided, which are arranged displaceably on a rail 40. The presence of these positioning elements 39 is determined by the initiator 38 and reported to the microprocessor via a line 41.

Im weiteren ist es mit Fig. 4 gezeigt, dass das Abtragorgan 2 mit einem Förderband 61 zusammenarbeitet, auf welchem die Faserballen aneinandergereiht, für das Abtragen aufgestellt werden. Das Förderband weist dabei ebenfalls einen Stoppmotor mit Getriebemotor und Zahnrad, sowie Initiator (ganze Antriebsgruppe nicht gezeigt) auf, wie dies für die Hubbewegung des Abtragorganes und für die Fahrbewegung des Maschinengestelles beschrieben worden ist. Die Signale des Initiators werden ebenfalls mit einer Leitung 62 (nur in Fig. 1 gezeigt) dem Mikroprozessor zugeführt, welcher die Leistungssignale über die Leitung 63 (Fig. 1) dem Stoppmotor des Förderbandes abgibt.It is further shown with FIG. 4 that the removal member 2 works together with a conveyor belt 61, on which the fiber bales are lined up, for removal. The conveyor belt also has a stop motor with gear motor and gear, and initiator (whole drive group not shown), as has been described for the lifting movement of the removal member and for the movement of the machine frame. The signals of the initiator are likewise fed to the microprocessor via a line 62 (only shown in FIG. 1), which delivers the power signals via line 63 (FIG. 1) to the stop motor of the conveyor belt.

Im Betrieb der Variante mit Fig. 4 führt das Abtragorgan einen örtlich festgelegten Weg zurück, weil die Faserballen mit dem Förderband jeweils um die notwendige Abtragtiefe zugeführt werden.In the operation of the variant with FIG. 4, the removal member leads back a locally fixed path because the fiber bales are fed by the conveyor belt in each case by the necessary removal depth.

Der Vorteil dieser Variante besteht darin, dass ein kontinuierlicher Betrieb möglich ist, weil das Förderband mit neuen Faserballen "nachgefüllt" werden kann.The advantage of this variant is that continuous operation is possible because the conveyor belt can be "refilled" with new fiber bales.

Es versteht sich, dass mittels den mit den Figuren 3 und 4 gezeigten Varianten, nur kleine Qualitätsmischungen mittels unterschiedlicher Faserballen durchgeführt werden können, z.B. dass lediglich jeder zweite Ballen eine zur ersten unterschiedliche Qualität aufweisen kann.It goes without saying that by means of the variants shown in FIGS. 3 and 4, only small quality blends can be carried out using different fiber bales, e.g. that only every second bale can have a different quality from the first.

Diesem Nachteil kann mit den, mit den Figuren 5 und 6 gezeigten Anordnungen, abgeholfen werden, indem, wie in Fig. 5 gezeigt, das Maschinengestell 3.1 mitsamt dem Abtragorgan 2 um die Schwenkachse 64 manuell oder in einer z.B. aus der deutschen Patentschrift Ni. 3208346 bekannten Weise automatisch drehbar vorgesehen ist, und das Abtragorgan 2 im wesentlichen gleichzeitig derart schwenkbar ist, dass die untere Abtragfläche des Abtragorganes in die von der Horizontalen abweichende, entsprechend gegenüber liegende Schräglage schwenkbar ist, was eine entsprechende Anpassung des Maschinengestells 3.1 und des Mikroprozessors erfordert. Der Einfachheit halber wurde der dazu notwendige maschinelle Aufwand in Fig. 5 nicht gezeigt.This disadvantage can be remedied with the arrangements shown in FIGS. 5 and 6 in that, as shown in FIG. 5, the machine frame 3.1 together with the removal member 2 about the pivot axis 64 manually or in a e.g. from the German patent specification Ni. 3208346 is provided automatically rotatably known, and the removal member 2 can be pivoted substantially simultaneously such that the lower removal surface of the removal member can be pivoted into the obliquely opposite, correspondingly opposite, oblique position, which requires a corresponding adjustment of the machine frame 3.1 and the microprocessor . For the sake of simplicity, the mechanical effort required for this has not been shown in FIG. 5.

Die Fig. 6 zeigt steuerungsmässig eine einfache, maschinenmässig jedoch aufwendigere Variante, indem das Maschinengestell 3.2 zwei in Linie angeordnete, jedoch in entgegengesetzter Richtung herausragende Abtragorgane 2 resp. 2.1 aufweist, so dass bei einer Abtragung in Schrägrichtung, falls jeder zweite Ballen eine von dem ersten abweichende Qualität aufweist, eine Mischung mit vier Qualitäten durchgeführt werden kann.6 shows, in terms of control, a simple, more complex, machine-based variant, in that the machine frame 3.2 has two removal elements 2, respectively, arranged in a line, but protruding in the opposite direction. 2.1, so that when removing in the oblique direction, if every second bale has a quality different from the first, a mixture with four qualities can be carried out.

Noch weiterführende Anordnungen der Faserballen zeigen die Figuren 7 und 8, indem eine Mehrzahl nebeneinander angeordneter Faserballen mit unterschiedlichen Qualitäten gleichzeitig abgetragen werden können. Dabei zeigt die Fig. 7 die Schwenkbarkeit des Maschinengestelles 3.1 und des Abtragorganes gemäss Beschreibungsteil für Fig. 5 und Fig. 8 die Doppelabtragorgan-Anordnung mit dem Maschinengestell 3.2 gemäss Beschreibungsteil für Fig. 6.FIGS. 7 and 8 show even further arrangements of the fiber bales, in that a plurality of fiber bales arranged next to one another with different qualities can be removed simultaneously. 7 shows the pivotability of the machine frame 3.1 and the removal member according to the description part for FIG. 5 and FIG. 8 shows the double removal element arrangement with the machine frame 3.2 according to the description part for FIG. 6.

Die Fig. 9 zeigt ein Abtragorgan 2.2 mit zwei Abtragwalzen 6a und 6b. Im übrigen sind die Funktionen dieselben, wie mit Fig. 2 gezeigt, weshalb für Elemente mit denselben Funktionen dieselben Bezugszeichen in Fig. 9 verwendet wurden.9 shows a removal member 2.2 with two removal rollers 6a and 6b. Otherwise, the functions are the same as shown in FIG. 2, which is why the same reference numerals have been used in FIG. 9 for elements with the same functions.

Im weiteren zeigt Fig. 10, dass auch sog. Portalanordnungen verwendet werden können, in welchen zwei Maschinengestelle 3.3 jeweils mittels Räder 35 auf Schienen (nicht gezeigt) fahrbar angeordnet sind, welche durch ein Abtragorgan 2.3 verbunden sind. Das Abtragen kann, wie in Fig. 3 oder 4 gezeigt, erfolgen. Die Funktionen sind für eine solche Portalvorrichtung dieselben wie für eine Abtragvorrichtung mit einseitigem Abtragorgan.10 further shows that so-called portal arrangements can also be used, in which two machine frames 3.3 are each movably arranged on rails (not shown) by means of wheels 35, which are connected by a removal member 2.3. The removal can take place as shown in FIG. 3 or 4. The functions for such a portal device are the same as for a removal device with a removal device on one side.
