Definitions
- the invention relates to a multi-bale opener with a fiber pressed bale to a horizontal removal plane leading to the removal level and a transversely guided in the removal level removal device, 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 fiber pressed bales set up in rows of bales 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 very different bale dimensions, so that manual height adjustment 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.
- the object of the invention is to develop 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 onto each transport track.
- Any desired mixing ratio 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 use a bale template to put together different lots 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 was dependent on the quantitative ratio of whole bales processed simultaneously.
- Each transport path can be raised in such a way that each fiber pressed bale has the same height as the adjacent bale rows at the beginning of the removal surface with its upper edge. Due to the different angle of the individual transport tracks to the removal level, a different metering 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 ablation 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 several fiber pressed bales arranged next to one another on separate transport lanes, fiber pressed bales or a fiber pressed bale mixture being fed to a uniform bale height via each transport lane and the setting of a specific mixing ratio from the fiber pressed bales supplied in the individual transport lanes or Fiber bale mixes on the transport speed of the individual transport lanes.
- the method according to the invention advantageously provides that the individual rows of fiber pressed bales are fed at different speeds, whereby the mixing ratio between the individual rows of fiber pressed bales 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 path. This ensures that all four rows of fiber pressed bales can be processed over the entire removal area.
- the individual rows of fiber pressed bales can themselves contain a bale mixture of fiber bales of the same height, the number of mixable fiber pressed bales depending on the number of fiber pressed bales which can be processed simultaneously in the removal surface in the direction of transport.
- 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 can accommodate four rows of bales 10, 12, 14, 16 next to one another in the exemplary embodiment of the drawings.
- the individual transport 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 rear section 20 in the manner of an ascending ramp rise in the area of a removal surface machined by the removal device 5 such 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 manner 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.
- a lifting device 22 e.g. 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 can be adjusted to a desired height using a suitable control device. 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 consists essentially of two counter-rotating milling drums 26, 27, which fling the removed fiber flakes upwards between them into a suction chamber 28, from which they are pneumatic can be removed 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 respect to their height of different dimensions. This makes it possible, e.g. Mix cotton bales of different origins with each other in any mixing ratio.
- the mixing ratio can namely be adjusted in a simple manner via the feed speed of the conveyor belts, so that in the exemplary embodiment according to FIG. 2 four different qualities can be processed with any mixture and constant mixing ratio.
- 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.

Abstract
Description
Die Erfindung betrifft einen Mehrballenöffner mit einer Faserpreßballen zu einer horizontalen Abtragebene führenden, zur Abtragebene schräg geführten Transporteinrichtung und einer in der Abtragsebene hin- und herbewegten Abtrageinrichtung, sowie ein Verfahren zur Öffnung und Mischung unterschiedlicher Faserpreßballen.The invention relates to a multi-bale opener with a fiber pressed bale to a horizontal removal plane leading to the removal level and a transversely guided in the removal level removal device, 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 aufgestellte Faserpreßballen 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 fiber pressed bales set up in rows of bales 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 Nachteil, daß sie im wesentlichen nur hinsichtlich der Größe einheitliche Partien Rohmaterial verarbeiten kann. Baumwollmischungen aus unterschiedlichen Provenienzen haben durchaus erheblich abweichende Ballenabmessungen, so daß ein manueller Höhenausgleich erfolgen muß, bevor die vorgesehene Baumwollmischung auf der bekannten Mehrballenöffnungsanlage abgearbeitet werden kann. Der Ausgleich der Höhenunterschiede erfolgt in der Praxis dadurch, daß von höheren Ballen ein oberer Abschnitt abgetrennt wird und auf die niedrigeren Ballen aufgesetzt wird. Dadurch wird allerdings das Mischungsverhältnis in der Partie erheblich variiert.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 very different bale dimensions, so that manual height adjustment 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.
Ein weiterer Nachteil besteht darin, daß Mischungsverhältnisse nur in Form von ganzzahligen Ballenanzahlverhältnissen einstellbar sind, nämlich im Rahmen der auf der Rampe gleichzeitig abgearbeiteten Ballen.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 Mehrballenöffner sowie ein Verfahren zur Öffnung und Mischung unterschiedlicher Faserpreßballen derart weiterzubilden, daß ein beliebig wählbares jederzeit änderbares Mischungsverhältnis einstellbar ist.The object of the invention is to develop 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 Ansprüche 1 bzw. 5.The features of
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 Transportgeschwindigkeit kann ein gewünschtes beliebiges Mischungsverhältnis mit hoher Genauigkeit eingestellt werden. Dabei ist wesentlich, daß dieses Mischungsverhältnis stufenlos einstellbar ist und jederzeit geändert werden kann. So ist es beispielsweise möglich, mit einer Ballenvorlage unterschiedliche Partien zusammenzustellen, ohne den Abarbeitungsvorgang zu unterbrechen. Um das Mischungsverhältnis zu ändern, ist es nicht notwendig, 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 onto each transport track. Any desired mixing ratio 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 use a bale template to put together different lots 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 beispielsweise 12,5 % erste Ballenreihe, 45 % zweite Ballenreihe, 21 % dritte Ballenreihe und 21,5 % vierte Ballenreihe. Derartige Mischungsverhältnisse waren zuvor nicht einstellbar, 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 was dependent on the quantitative ratio of whole bales processed simultaneously.
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 unterschiedlichen Winkels der einzelnen Transportbahnen zur Abtragsebene ergibt sich zwar unter Voraussetzung gleicher Transportgeschwindigkeiten ein unterschiedlicher Dosierhub, der aber durch Einstellung entsprechender Transportgeschwindigkeiten kompensiert werden kann.Each transport path can be raised in such a way that each fiber pressed bale has the same height as the adjacent bale rows at the beginning of the removal surface with its upper edge. Due to the different angle of the individual transport tracks to the removal level, a different metering 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 Transportbahnen quer zur Transportrichtung entspricht. Bei diesem bevorzugten Ausführungsbeispiel wird die Abtragvorrichtung, z.B. eine Fräseinrichtung, parallel zur Transportrichtung 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 ablation 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 Faserpreßballenmischung einer einheitlichen Ballenhöhe zugeführt wird und das Einstellen eines bestimmten Mischungsverhältnisses aus den in den einzelnen Transportbahnen zugeführten Faserpreßballen oder Faserpreßballenmischungen über die Transportgeschwindigkeit der einzelnen Transportbahnen.The method for opening and mixing different fiber pressed bales is characterized according to the invention by feeding several fiber pressed bales arranged next to one another on separate transport lanes, fiber pressed bales or a fiber pressed bale mixture being fed to a uniform bale height via each transport lane and the setting of a specific mixing ratio from the fiber pressed bales supplied in the individual transport lanes or Fiber bale mixes on the transport speed of the individual transport lanes.
Das erfindungsgemäße Verfahren sieht in vorteilhafter Weise vor, daß die einzelnen Faserpreßballenreihen unterschiedlich schnell zugeführt werden, wodurch das Mischungsverhältnis zwischen den einzelnen Faserpreßballenreihen exakt eingestellt werden kann. Dabei ist ein einheitlicher Rampenwinkel der einzelnen Transportbahnen vorgesehen. Niedrigere Ballen treten dadurch zu einem späteren Zeitpunkt in die Abtragsfläche ein, was allerdings durch eine höhere Transportgeschwindigkeit kompensiert werden kann.The method according to the invention advantageously provides that the individual rows of fiber pressed bales are fed at different speeds, whereby the mixing ratio between the individual rows of fiber pressed bales 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 nebeneinander angeordneter Faserpreßballenreihen unterschiedlicher Höhe durch Variieren des Rampenwinkels für jede Transportbahn. Auf diese Weise ist gewährleistet, daß alle vier Faserpreßballenreihen über die gesamte Abtragsfläche 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 path. This ensures that all four rows of fiber pressed bales can be processed over the entire removal area.
Die einzelnen Faserpreßballenreihen können selbst eine Ballenmischung gleich hoher Faserpreßballen enthalten, wobei die Anzahl der mischbaren Faserpreßballen von der Anzahl der in der Abtragsfläche in Transportrichtung gleichzeitig bearbeitbarer Faserpreßballen abhängt.The individual rows of fiber pressed bales can themselves contain a bale mixture of fiber bales of the same height, the number of mixable fiber pressed bales depending on the number of fiber pressed bales which can be processed simultaneously in the removal surface in the direction of transport.
Im folgenden wird unter Bezugnahme auf die Zeichnungen ein Ausführungsbeispiel der Erfindung näher erläutert.In the following an embodiment of the invention will be explained with reference to the drawings.

Der Mehrballenöffner 1 weist eine Transporteinrichtung aus mehreren parallel zueinander verlaufenden nebeneinander angeordneten Transportbahnen 2,4,6,8 auf, die bei dem Ausführungsbeispiel der Zeichnungen vier Ballenreihen 10,12,14,16 nebeneinander aufnehmen können.The
Die einzelnen Transportbahnen 2,4,6,8 bestehen vorzugsweise 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 Transportbahnen 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
Die Transportbahnen 2,4,6,8 sind vorzugsweise ein- oder mehrfach unterteilt, wobei die letzte Unterteilung zu Beginn der Abtragsfläche 3 vorgesehen ist. Die unterteilten Transportbahnen 2,4,6,8 können, wie aus Fig.l ersichtlich, miteinander über einen Zahnriemen oder dergleichen gekoppelt sein. Der vordere Transportbahnabschnitt 18 ist an seinem in Transportrichtung vorderen Ende ebenfalls schwenkbar gelagert, um ein unterschiedliches Anheben der Ballenreihen 10,12,14,16 bereits in dem ersten Transportbahnabschnitt 18 zu ermöglichen und einen guasi stufenlosen Übergang zu dem letzten Transportbahnabschnitt 20 zu ermöglichen.The
Das Anheben der Transportbahnen im Bereich der Abtragsfläche erfolgt mit einer Hubvorrichtung 22, z.B. Linearmotoren wie hydraulischen Kolbenzylindereinheiten, die, wie beispielsweise aus Fig. 2 ersichtlich, paarweise seitlich der Transportbahnen 2,4,6,8 angeordnet werden können, und mit einer geeigneten Steuervorrichtung auf eine gewünschte Höhe einstellbar sind. Ähnliche Hubvorrichtungen können auch für den vorderen Transportbahnabschnitt 18 vorgesehen sein. Die nebeneinander angeordneten 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 lifting of the transport tracks in the area of the removal surface takes place with a
Gemäß dem Ausführungsbeispiel der Fig. 1 überdeckt die Abtragsfläche 3 in Transportrichtung etwa die Länge von vier hintereinander angeordneten Ballen innerhalb jeder Ballenreihe 10,12,14,16.According to the exemplary embodiment in FIG. 1, the
Die Abtragvorrichtung 5 ist in Fig. 1 in ihrer in Transportrichtung hinteren Endstellung gezeigt, wobei bei jeder Hin- und Herbewegung der Abtragvorrichtung 5 die insgesamt 16 auf der Rampe befindlichen Ballen entsprechend ihrer Zustellung abgearbeitet werden.The
Die Abtragvorrichtung 5 besteht im wesentlichen aus zwei gegensinnig rotierenden Fräswalzen 26,27, die die abgetragenen Faserflocken zwischen sich nach oben in einen Absaugraum 28 schleudern, von dem aus sie pneumatisch über eine Absaugleitung 30 abtransportiert werden. Die Abtragvorrichtung 5 wird mit Hilfe einer Rollen/Schienenkonstruktion 32,34 geradlinig über die Abtragfläche 3 geführt.The
Dadurch, daß zu Beginn der Abtragfläche 3 die Höhe der Transportbahnen 2,4,6,8 der jeweiligen Ballenhöhe angepaßt wird, können auf den einzelnen Transportbahnen Ballen hinsichtlich ihrer Höhe unterschiedlicher Abmessungen aufgelegt werden. Dadurch ist es möglich, z.B. Baumwollballen unterschiedlicher Provenienzen miteinander in einem beliebigen Mischungsverhältnis zu mischen.Because the height of the
Das Mischungsverhältnis kann nämlich in einfacher Weise über die Zustellgeschwindigkeit der Transportbänder eingestellt werden, so daß bei dem Ausführungsbeispiel gemäß Fig. 2 vier unterschiedliche Qualitäten mit beliebiger Mischung und konstantem Mischungsverhältnis abgearbeitet werden können.The mixing ratio can namely be adjusted in a simple manner via the feed speed of the conveyor belts, so that in the exemplary embodiment according to FIG. 2 four different qualities can be processed with any mixture and constant mixing ratio.
Auch eine Umstellung der Partie auf eine andere Mischung ist problemlos möglich, ohne daß die Ballenvorlage ausgetauscht werden muß. Soll die neue Mischung beispielsweise nur Baumwollprovenienzen enthalten, die in der Ballenreihe 10,14 und 16 enthalten sind, ist es auch möglich, die Transportbahn der Ballenreihe 12 stillzusetzen.Switching the batch to a different mixture is also possible without the need to replace the bale template. If, for example, the new mixture should only contain cotton provenances that are contained in the
Der Mehrballenöffner 1 eröffnet also die Möglichkeit, mit einer einheitlichen Ballenvorlage unterschiedliche Partien mit unterschiedlichen Mischungsverhältnissen zusammenzustellen und zu verarbeiten.The
Die in der vorstehenden Beschreibung, in den Zeichnungen sowie in den Ansprüchen offenbarten Merkmale der Erfindung, auch wenn sie nur in Verbindung mit einem bestimmten Ausführungsbeispiel beschrieben sind, sollen sowohl einzeln als auch in beliebiger Kombination für die Verwirklichung der Erfindung in ihren verschiedenen Ausführungsformen wesentlich sein.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 to be essential both individually and in any combination for the implementation of the invention in its various embodiments .
