Definitions
- the invention relates to a multi-bale opener with a fiber pressed bale leading to a horizontal removal plane, transversely guided to the removal level transport device and a removal device moved to and fro in the removal level, and a method for opening and mixing different fiber pressed bales.
- bale opening device is known from DE-OS 20 61 044, according to which the fiber press bales set up in bale rows can be continuously pushed in the longitudinal direction thereof during processing.
- the opening device can be moved back and forth along a straight guide relative to the rows of bales, while the fiber material is fed along an ascending ramp.
- Such a multi-bale opening system has the disadvantage that it can only process batches of raw material that are uniform in size.
- Cotton blends from different provenances have considerably different bale dimensions, so that manual height compensation must take place before the intended cotton blend can be processed on the known multi-bale opening system.
- the height differences are compensated for by separating an upper section from higher bales and placing them on the lower bales.
- this considerably varies the mixing ratio in the batch.
- Another disadvantage is that mixing ratios can only be set in the form of integer bale number ratios, namely within the scope of the bales processed simultaneously on the ramp.
- the invention is based on the object of developing a multi-bale opener and a method for opening and mixing different fiber pressed bales in such a way that an arbitrarily selectable mixing ratio which can be changed at any time can be set.
- the transport device according to the invention with a plurality of mutually independent transport tracks arranged next to one another makes it possible, for example, to transport different cotton provenances with different bale dimensions to each transport track; a desired mixing ratio of any desired can be set with high accuracy via the transport speed. It is essential that this mixing ratio is infinitely adjustable and can be changed at any time. For example, it is possible to put together different lots with one bale feed without interrupting the processing process. In order to change the mixing ratio, it is not necessary to change the bale arrangement.
- any mixing ratio between the four bale rows can be set, for example 12.5% first bale row, 45% second bale row, 21% third bale row and 21.5% fourth bale row.
- Mixing ratios of this type could not previously be set, since the composition of the mixture relied on the quantitative ratio of simultaneously processed whole bales.
- Each transport path can be raised in such a way that each fiber bale at the beginning of the removal surface has the same height with its upper edge as the adjacent rows of bales. Due to the different angle of the individual transport tracks to the removal level, a different dosing stroke results, assuming the same transport speeds, but this can be compensated for by setting corresponding transport speeds.
- the removal device can be moved back and forth parallel to the transport direction in the region of the removal surface, the length of the removal device corresponding to the width of all transport tracks transverse to the transport direction.
- the removal device e.g. a milling device, guided parallel to the transport direction.
- the method for opening and mixing different fiber pressed bales is characterized according to the invention by feeding a plurality of fiber pressed bales arranged next to one another on separate transport lanes, fiber pressed bales or a fiber pressed bale mixture being fed via a uniform bale height and the setting of a specific mixing ratio from the feeds fed into the individual transport lanes Fiber pressed bales or fiber pressed bale mixtures via the transport speed of the individual transport webs.
- the method according to the invention advantageously provides that the individual fiber press bale rows are fed at different speeds, whereby the mixing ratio between the individual fiber press bale rows can be set exactly.
- a uniform ramp angle of the individual transport tracks is provided. As a result, lower bales enter the removal area at a later point in time, but this can be compensated for by a higher transport speed.
- a plurality of fiber-pressed bale rows of different heights are arranged next to one another by varying the ramp angle for each transport track. This ensures that all four rows of fiber pressed bales can be processed over the entire removal area.
- the individual fiber pressed bale rows can themselves contain a bale mix of equal high pressed bales, the number of mixable fiber pressed bales depending on the number of fiber pressed bales that can be processed simultaneously in the removal area in the direction of transport.
- Fig. 1 a multi-bale opener according to the invention in
- Fig. 2 shows a cross section through the multi-bale opener along the line II-II in Fig. 1st
- the multi-bale opener 1 has a transport device consisting of a plurality of transport tracks 2, 4, 6, 8 arranged parallel to one another and which, in the exemplary embodiment of the drawings, can accommodate four rows of bales 10, 12, 14, 16 next to one another.
- the individual conveyor tracks 2, 4, 6, 8 preferably consist of endlessly driven conveyor belts which run essentially horizontally in a section 18 at the front in the transport direction, on which the batch can be placed, and in a section 20 in the manner of a ascending ramp in the region of a removal surface processed by the removal device 5 so that the end section of the treadmill reaches as far as the removal level of the removal surface 3.
- the transport tracks 2, 4, 6, 8 are held in bearings 23 at this upper end of the treadmill so as to be pivotable about a common axis of rotation, the lower end of the inclined transport tracks 2, 4, 6, 8 being raised in this way depending on the height of the bales presented can that the upper edges of the respective rows of bales presented enter the removal level of the removal surface 3 at the same height.
- the transport tracks 2, 4, 6, 8 are preferably subdivided one or more times, the last subdivision being provided at the beginning of the removal surface 3.
- the divided transport tracks 2, 4, 6, 8 can, as can be seen from FIG. 1, be coupled to one another via a toothed belt or the like.
- the front transport track section 18 is also pivotally mounted at its front end in the transport direction in order to raise the bale rows 10, 12, 14, 16 differently to enable already in the first transport track section 18 and to enable a virtually stepless transition to the last transport track section 20.
- the transport tracks are lifted in the area of the removal surface by means of a lifting device 22, for example linear motors such as hydraulic piston-cylinder units, which, as can be seen, for example, from FIG. 2, can be arranged in pairs to the side of the transport tracks 2, 4, 6, 8, and are ein ⁇ tellbar with an appropriate control device to a desired 'level. Similar lifting devices can also be provided for the front transport track section 18.
- the rows of bales 10, 12, 14, 16 arranged next to one another, as can be seen in FIG. 2, are guided from side support walls to the end of the ramp formed by the transport tracks 2, 4, 6, 8.
- the removal surface 3 covers approximately the length of four bales arranged one behind the other within each row of bales 10, 12, 14, 16 in the transport direction.
- the removal device 5 is shown in FIG. 1 in its rear end position in the transport direction, with each time the removal device 5 is moved back and forth, the total of 16 bales located on the ramp are processed in accordance with their delivery.
- the removal device 5 essentially consists of two milling rollers 26, 27 rotating in opposite directions, which fling the removed fiber flakes upwards between them into a suction chamber 28, from which they pneumatically be transported away via a suction line 30.
- the removal device 5 is guided in a straight line over the removal surface 3 with the aid of a roller / rail construction 32, 34.
- bales can be placed on the individual transport tracks with regard to their height, different dimensions. This makes it possible, e.g. To mix cotton bales of different provenances with one another in any desired mixing ratio.
- the mixing ratio can namely be set in a simple manner via the delivery speed of the conveyor belts, so that in the embodiment according to FIG. 2 four different qualities can be processed with any mixture and constant mixing ratio.
- bale feed it is also possible to change the batch to another mix without any problems, without having to replace the bale feed.
- the new mixture should only contain cotton provenances that are contained in the bale rows 10, 14 and 16, it is also possible to stop the transport path of the bale row 12.
- the multi-bale opener 1 thus opens up the possibility of assembling and processing different batches with different mixing ratios using a uniform bale template.

MehrballenöffnerMulti-bale opener
Die Erfindung betrifft einen Mehrballenöffner mit einer Faserpreßballen zu einer horizontalen Abtragebene füh¬ renden, zur Abtragebene schräg geführten Transportein¬ richtung und einer in der Abtragsebene hin- und herbe¬ wegten Abtrageinrichtung, sowie ein Verfahren zur Öff¬ nung und Mischung unterschiedlicher Faserpreßballen.The invention relates to a multi-bale opener with a fiber pressed bale leading to a horizontal removal plane, transversely guided to the removal level transport device and a removal device moved to and fro in the removal level, and a method for opening and mixing different fiber pressed bales.
Eine derartige Ballenöffnungsvorrichtung ist aus der DE-OS 20 61 044 bekannt, gemäß der in Ballenreihen auf¬ gestellte Faεerpreßballen in Längsrichtung derselben während des Abarbeitens kontinuierlich nachgeschoben werden können. Hierbei kann die Öffnungsvorrichtung längs einer Geradführung relativ zu den Ballenreihen hin- und herbewegt werden, während das Fasergut längs einer aufsteigenden Rampe zugeführt wird.Such a bale opening device is known from DE-OS 20 61 044, according to which the fiber press bales set up in bale rows can be continuously pushed in the longitudinal direction thereof during processing. Here, the opening device can be moved back and forth along a straight guide relative to the rows of bales, while the fiber material is fed along an ascending ramp.
Eine derartige Mehrballenöffnungsanlage hat den Nach¬ teil, daß sie im wesentlichen nur hinsichtlich der Größe einheitliche Partien Rohmaterial verarbeiten kann. Baumwollmischungen aus unterschiedlichen Prove¬ nienzen haben durchaus erheblich abweichende Ballen¬ abmessungen, so daß ein manueller Höhenausgleich er¬ folgen muß, bevor die vorgesehene Baumwollmischung auf der bekannten Mehrballenöffnungsanlage abgearbeitet werden kann. Der Ausgleich der Höhenunterschiede er¬ folgt in der Praxis dadurch, daß von höheren Ballen ein oberer Abschnitt abgetrennt wird und auf die niedrige¬ ren Ballen aufgesetzt wird. Dadurch wird allerdings das Mischungsverhältnis in der Partie erheblich variiert.
Ein weiterer Nachteil besteht darin, daß Mischungsver¬ hältnisse nur in Form von ganzzahligen Ballenanzahlver¬ hältnissen einstellbar sind, nämlich im Rahmen der auf der Rampe gleichzeitig abgearbeiteten Ballen.Such a multi-bale opening system has the disadvantage that it can only process batches of raw material that are uniform in size. Cotton blends from different provenances have considerably different bale dimensions, so that manual height compensation must take place before the intended cotton blend can be processed on the known multi-bale opening system. In practice, the height differences are compensated for by separating an upper section from higher bales and placing them on the lower bales. However, this considerably varies the mixing ratio in the batch. Another disadvantage is that mixing ratios can only be set in the form of integer bale number ratios, namely within the scope of the bales processed simultaneously on the ramp.
Der Erfindung liegt die Aufgabe zugrunde, einen Mehr¬ ballenöffner sowie ein Verfahren zur Öffnung und Mischung unterschiedlicher Faserpreßballen derart weiterzubilden, daß ein beliebig wählbares jederzeit änderbares Mischungsverhältnis einstellbar ist.The invention is based on the object of developing a multi-bale opener and a method for opening and mixing different fiber pressed bales in such a way that an arbitrarily selectable mixing ratio which can be changed at any time can be set.
Zur Lösung dieser Aufgabe dienen die Merkmale der An¬ sprüche 1 bzw. 5.The features of claims 1 and 5 serve to achieve this object.
Die erfindungsgemäße Transporteinrichtung mit mehreren nebeneinander angeordneten voneinander unabhängigen Transportbahnen ermöglicht es beispielsweise, auf jede Transportbahn unterschiedliche Baumwollprovenienzen mit verschiedenen Ballenabmessungen zu transportieren, über die Transportgeεchwiήdigkeit kann ein gewünschtes belie¬ biges Mischungsverhältnis mit hoher Genauigkeit einge¬ stellt werden. Dabei ist wesentlich, daß dieses Mischungs¬ verhältnis stufenlos einstellbar ist und jederzeit ge¬ ändert werden kann. So ist es beispielsweise möglich, mit einer Ballenvorlage unterschiedliche Partien zusammen¬ zustellen, ohne den Abarbeitungsvorgang zu unterbrechen. Um das Mischungsverhältnis zu ändern, ist es nicht not¬ wendig, die Ballenanordnung zu verändern.The transport device according to the invention with a plurality of mutually independent transport tracks arranged next to one another makes it possible, for example, to transport different cotton provenances with different bale dimensions to each transport track; a desired mixing ratio of any desired can be set with high accuracy via the transport speed. It is essential that this mixing ratio is infinitely adjustable and can be changed at any time. For example, it is possible to put together different lots with one bale feed without interrupting the processing process. In order to change the mixing ratio, it is not necessary to change the bale arrangement.
Abgesehen von der Genauigkeit der Einstellung des Mischungsverhältnisses besteht ein weiterer Vorteil darin, daß jedes beliebige Mischungsverhältnis zwischen den vier Ballenreihen einstellbar ist, also beispiels¬ weise 12,5 % erste Ballenreihe, 45 % zweite Ballenreihe,
21 % dritte Ballenreihe und 21,5 % vierte Ballenreihe. Derartige Mischungsverhältnisse waren zuvor nicht ein¬ stellbar, da man für die Zusammenstellung der Mischung auf das Mengenverhältnis gleichzeitig abgearbeiteter ganzer Ballen angewiesen war.Apart from the accuracy of the setting of the mixing ratio, there is a further advantage that any mixing ratio between the four bale rows can be set, for example 12.5% first bale row, 45% second bale row, 21% third bale row and 21.5% fourth bale row. Mixing ratios of this type could not previously be set, since the composition of the mixture relied on the quantitative ratio of simultaneously processed whole bales.
Dabei kann jede Transportbahn derart angehoben werden, daß jeder Faserpreßballen zu Beginn der Abtragsfläche mit seiner Oberkante die gleiche Höhe aufweist wie die benachbarten Ballenreihen. Auf Grund des unterschiedli¬ chen Winkels der einzelnen Transportbahnen zur Abtrags¬ ebene ergibt sich zwar unter Voraussetzung gleicher Transportgeschwindigkeiten ein unterschiedlicher Dosier¬ hub, der aber durch Einstellung entsprechender Trans- portgeεchwindigkeiten kompensiert werden kann.Each transport path can be raised in such a way that each fiber bale at the beginning of the removal surface has the same height with its upper edge as the adjacent rows of bales. Due to the different angle of the individual transport tracks to the removal level, a different dosing stroke results, assuming the same transport speeds, but this can be compensated for by setting corresponding transport speeds.
Vorzugsweise ist vorgesehen, daß die Abtragvorrichtung parallel zur Transportrichtung im Bereich der Abtragsfläche hin- und herbewegbar ist, wobei die Länge der Abtragvorrichtung der Breite aller Tranεportbahnen quer zur Transportrichtung entspricht. Bei diesem bevorzug¬ ten Ausführungsbeispiel wird die Abtragvorrichtung, z.B. eine Fräseinrichtung, parallel zur Transportrich¬ tung geführt.It is preferably provided that the removal device can be moved back and forth parallel to the transport direction in the region of the removal surface, the length of the removal device corresponding to the width of all transport tracks transverse to the transport direction. In this preferred embodiment, the removal device, e.g. a milling device, guided parallel to the transport direction.
Das Verfahren zum öffnen und Mischen unterschiedlicher Faserpreßballen ist erfindungsgemäß gekennzeichnet durch das Zuführen mehrerer nebeneinander angeordneter Faserpreßballen auf separaten Transportbahnen, wobei über jede Transportbahn Faserpreßballen oder eine Faserpreßballenmiεchung einer einheitlichen Ballenhöhe zugeführt wird und das Einstellen eines bestimmten Mischungsverhältnisses aus den in den einzelnen Trans¬ portbahnen zugeführten Faserpreßballen oder Faserpre߬ ballenmischungen über die Transportgeschwindigkeit der einzelnen Tranεportbahnen.
Das erfindungsgemäße Verfahren sieht in vorteilhafter Weise vor, daß die einzelnen Faserpreßballenreihen unterschiedlich schnell zugeführt werden, wodurch das Mischungsverhältnis zwischen den einzelnen Faserpre߬ ballenreihen exakt eingestellt werden kann. Dabei ist ein einheitlicher Rampenwinkel der einzelnen Transport¬ bahnen vorgesehen. Niedrigere Ballen treten dadurch zu einem späteren Zeitpunkt in die Abtragsfläche ein, was allerdings durch eine höhere Transportgeschwindigkeit kompensiert werden kann.The method for opening and mixing different fiber pressed bales is characterized according to the invention by feeding a plurality of fiber pressed bales arranged next to one another on separate transport lanes, fiber pressed bales or a fiber pressed bale mixture being fed via a uniform bale height and the setting of a specific mixing ratio from the feeds fed into the individual transport lanes Fiber pressed bales or fiber pressed bale mixtures via the transport speed of the individual transport webs. The method according to the invention advantageously provides that the individual fiber press bale rows are fed at different speeds, whereby the mixing ratio between the individual fiber press bale rows can be set exactly. A uniform ramp angle of the individual transport tracks is provided. As a result, lower bales enter the removal area at a later point in time, but this can be compensated for by a higher transport speed.
Bevorzugt erfolgt aber das Zuführen mehrerer nebenein¬ ander angeordneter Faserpreßballenreihen unterschied¬ licher Höhe durch Variieren des Rampenwinkels für jede Tranεportbahn. Auf diese Weise ist gewährleistet, daß alle vier Faserpreßballenreihen über die gesamte Ab¬ tragsfläche bearbeitet werden können.Preferably, however, a plurality of fiber-pressed bale rows of different heights are arranged next to one another by varying the ramp angle for each transport track. This ensures that all four rows of fiber pressed bales can be processed over the entire removal area.
Die einzelnen Faserpreßballenreihen können εelbεt eine Ballenmiεchung gleich hoher Faεerpreßballen enthalten, wobei die Anzahl der mischbaren Faserpreßballen von der Anzahl der in der Abtragsfläche in Transpόrtrichtung gleichzeitig bearbeitbarer Faserpreßballen abhängt.The individual fiber pressed bale rows can themselves contain a bale mix of equal high pressed bales, the number of mixable fiber pressed bales depending on the number of fiber pressed bales that can be processed simultaneously in the removal area in the direction of transport.
Im folgenden wird unter Bezugnahme auf die Zeichnungen ein Auεführungεbeispiel der Erfindung näher erläutert.An exemplary embodiment of the invention is explained in more detail below with reference to the drawings.
Es zeigen:Show it:
Fig. 1 einen Mehrballenöffner gemäß der Erfindung imFig. 1 a multi-bale opener according to the invention in
Aufriß und im Schema und Fig. 2 einen Querschnitt durch den Mehrballenöffner entlang der Linie II-II in Fig. 1.
Der Mehrballenöffner 1 weist eine Transporteinrichtung aus mehreren parallel zueinander verlaufenden nebenein¬ ander angeordneten Transportbahnen 2,4,6,8 auf, die bei dem Ausführungεbeispiel der Zeichnungen vier Ballenrei¬ hen 10,12,14,16 nebeneinander aufnehmen können.Aufriß and in the scheme and Fig. 2 shows a cross section through the multi-bale opener along the line II-II in Fig. 1st The multi-bale opener 1 has a transport device consisting of a plurality of transport tracks 2, 4, 6, 8 arranged parallel to one another and which, in the exemplary embodiment of the drawings, can accommodate four rows of bales 10, 12, 14, 16 next to one another.
Die einzelnen Transportbahnen 2,4,6,8 bestehen vorzugs¬ weise aus endlos angetriebenen Transportbändern, die in einem in Transportrichtung vorderen Abschnitt 18, auf dem die Partie vorgelegt werden kann, im wesentlichen horizontal verlaufen und in einem hinteren Abschnitt 20 in der Art einer aufsteigenden Rampe im Bereich einer von der Abtrageinrichtung 5 bearbeiteten Abtragfläche derart ansteigen, daß der Endabschnitt des Laufbandes bis an die Abtragebene der Abtragfläche 3 heranreicht. Die Transportbahnen 2,4,6,8 sind an diesem oberen Ende des Laufbandes um eine gemeinsame Drehachse schwenkbar in Lagerungen 23 gehalten, wobei das untere Ende der schräg verlaufenden Tranεportbahnen 2,4,6,8 je nach Höhe der vorgelegten Ballen derart angehoben werden kann, daß die Oberkanten der jeweiligen vorgelegten Ballenreihen auf gleicher Höhe in die Abtragsebene der Abtragsfläche 3 eintreten.The individual conveyor tracks 2, 4, 6, 8 preferably consist of endlessly driven conveyor belts which run essentially horizontally in a section 18 at the front in the transport direction, on which the batch can be placed, and in a section 20 in the manner of a ascending ramp in the region of a removal surface processed by the removal device 5 so that the end section of the treadmill reaches as far as the removal level of the removal surface 3. The transport tracks 2, 4, 6, 8 are held in bearings 23 at this upper end of the treadmill so as to be pivotable about a common axis of rotation, the lower end of the inclined transport tracks 2, 4, 6, 8 being raised in this way depending on the height of the bales presented can that the upper edges of the respective rows of bales presented enter the removal level of the removal surface 3 at the same height.
Die Transportbahnen 2,4,6,8 sind vorzugsweise ein- oder mehrfach unterteilt, wobei die letzte Unterteilung zu Beginn der Abtragsfläche 3 vorgesehen ist. Die unter¬ teilten Transportbahnen 2,4,6,8 können, wie aus Fig.l ersichtlich, miteinander über einen Zahnriemen oder dergleichen gekoppelt sein. Der vordere Transportbahn¬ abschnitt 18 ist an seinem in Transportrichtung vor¬ deren Ende ebenfalls schwenkbar gelagert, um ein un¬ terschiedliches Anheben der Ballenreihen 10,12,14,16
bereits in dem ersten Transportbahnabschnitt 18 zu ermöglichen und einen quasi stufenlosen Übergang zu dem letzten Transportbahnabschnitt 20 zu ermöglichen.The transport tracks 2, 4, 6, 8 are preferably subdivided one or more times, the last subdivision being provided at the beginning of the removal surface 3. The divided transport tracks 2, 4, 6, 8 can, as can be seen from FIG. 1, be coupled to one another via a toothed belt or the like. The front transport track section 18 is also pivotally mounted at its front end in the transport direction in order to raise the bale rows 10, 12, 14, 16 differently to enable already in the first transport track section 18 and to enable a virtually stepless transition to the last transport track section 20.
Das Anheben der Transportbahnen im Bereich der Abtrags¬ fläche erfolgt mit einer Hubvorrichtung 22, z.B. Linear¬ motoren wie hydraulischen Kolbenzylindereinheiten, die, wie beispielsweise aus Fig. 2 ersichtlich, paarweise seitlich der Tranεportbahnen 2,4,6,8 angeordnet werden können, und mit einer geeigneten Steuervorrichtung auf eine gewünschte 'Höhe einεtellbar sind. Ähnliche Hubvor¬ richtungen können auch für den vorderen Tranεportbahn- abschnitt 18 vorgesehen sein. Die nebeneinander ange¬ ordneten Ballenreihen 10,12,14,16 werden, wie aus Fig. 2 ersichtlich, von seitlichen Stützwänden bis zu dem Ende der aus den Transportbahnen 2,4,6,8 gebildeten Rampe geführt.The transport tracks are lifted in the area of the removal surface by means of a lifting device 22, for example linear motors such as hydraulic piston-cylinder units, which, as can be seen, for example, from FIG. 2, can be arranged in pairs to the side of the transport tracks 2, 4, 6, 8, and are einεtellbar with an appropriate control device to a desired 'level. Similar lifting devices can also be provided for the front transport track section 18. The rows of bales 10, 12, 14, 16 arranged next to one another, as can be seen in FIG. 2, are guided from side support walls to the end of the ramp formed by the transport tracks 2, 4, 6, 8.
Gemäß dem Ausführungεbeiεpiel der Fig. 1 überdeckt die Abtragεfläche 3 in Tranεportrichtung etwa die Länge von vier hintereinander angeordneten Ballen innerhalb jeder Ballenreihe 10,12,14,16.1, the removal surface 3 covers approximately the length of four bales arranged one behind the other within each row of bales 10, 12, 14, 16 in the transport direction.
Die Abtragvorrichtung 5 ist in Fig. 1 in ihrer in Trans¬ portrichtung hinteren Endstellung gezeigt, wobei bei jeder Hin- und Herbewegung der Abtragvorrichtung 5 die insgesamt 16 auf der Rampe befindlichen Ballen entspre¬ chend ihrer Zustellung abgearbeitet werden.The removal device 5 is shown in FIG. 1 in its rear end position in the transport direction, with each time the removal device 5 is moved back and forth, the total of 16 bales located on the ramp are processed in accordance with their delivery.
Die Abtragvorrichtung 5 besteht im wesentlichen aus zwei gegensinnig rotierenden Fräεwalzen 26,27, die die abgetragenen Faserflocken zwischen sich nach oben in einen Absaugraum 28 schleudern, von dem aus sie pneuma-
tisch über eine Absaugleitung 30 abtransportiert wer¬ den. Die Abtragvorrichtung 5 wird mit Hilfe einer Rollen/Schienenkonstruktion 32,34 geradlinig über die Abtragfläche 3 geführt.The removal device 5 essentially consists of two milling rollers 26, 27 rotating in opposite directions, which fling the removed fiber flakes upwards between them into a suction chamber 28, from which they pneumatically be transported away via a suction line 30. The removal device 5 is guided in a straight line over the removal surface 3 with the aid of a roller / rail construction 32, 34.
Dadurch, daß zu Beginn der Abtragfläche 3 die Höhe der Transportbahnen 2,4,6,8 der jeweiligen Ballenhöhe ange¬ paßt wird, können auf den einzelnen Tranεportbahnen Ballen hinsichtlich ihrer Höhe unterschiedlicher Abmes¬ sungen aufgelegt werden. Dadurch ist es möglich, z.B. Baumwollballen unterschiedlicher Provenienzen mitein¬ ander in einem beliebigen Miεchungεverhältniε zu miεchen.Because the height of the transport tracks 2, 4, 6, 8 is adapted to the respective bale height at the beginning of the removal surface 3, bales can be placed on the individual transport tracks with regard to their height, different dimensions. This makes it possible, e.g. To mix cotton bales of different provenances with one another in any desired mixing ratio.
Daε Miεchungεverhältnis kann nämlich in einfacher Weise über die Zustellgeschwindigkeit der Transportbänder eingestellt werden, εo daß bei dem Auεführungεbeispiel gemäß Fig. 2 vier unterschiedliche Qualitäten mit be¬ liebiger Mischung und konεtantem Mischungsverhältniε abgearbeitet werden können.The mixing ratio can namely be set in a simple manner via the delivery speed of the conveyor belts, so that in the embodiment according to FIG. 2 four different qualities can be processed with any mixture and constant mixing ratio.
Auch eine Umεtellung der Partie auf eine andere Miεchung ist problemlos möglich, ohne daß die Ballenvorlage aus¬ getauscht werden muß. Soll die neue Mischung beispielε- weiεe nur Baumwollprovenienzen enthalten, die in der Ballenreihe 10,14 und 16 enthalten sind, ist es auch möglich, die Transportbahn der Ballenreihe 12 stillzu- εetzen.It is also possible to change the batch to another mix without any problems, without having to replace the bale feed. For example, if the new mixture should only contain cotton provenances that are contained in the bale rows 10, 14 and 16, it is also possible to stop the transport path of the bale row 12.
Der Mehrballenöffner 1 eröffnet also die Möglichkeit, mit einer einheitlichen Ballenvorlage unterschiedliche Partien mit unterschiedlichen Mischungsverhältniεsen zusammenzuεtellen und zu verarbeiten.
Die in der vorstehenden Beschreibung, in den Zeichnungen sowie in den Ansprüchen offenbarten Merkmale der Erfin¬ dung, auch wenn sie nur in Verbindung mit einem bestimm¬ ten Ausführungεbeiεpiel beschrieben sind, sollen sowohl einzeln als auch in beliebiger Kombination für die Ver¬ wirklichung der Erfindung in ihren verschiedenen Aus¬ führungsformen wesentlich sein.
The multi-bale opener 1 thus opens up the possibility of assembling and processing different batches with different mixing ratios using a uniform bale template. The features of the invention disclosed in the above description, in the drawings and in the claims, even if they are only described in connection with a specific exemplary embodiment, are intended both individually and in any combination for realizing the invention be essential in their various embodiments.
