Definitions
- the invention relates to a baler according to the preamble of claim 1, as it is known from EP 1 190 618 A1 is known.
- a baler for loose pressed material especially paper described, which can be used as a channel baler with hydraulic drive for a stationary high-performance operation, but nevertheless instead of the usual wire wrapping a binding with binding material provides, which is to close each by means of a knotter.
- This necking with binding material has its own tradition with mobile harvesters, with central drive from a tractor and continuous, non-stationary movement of the elements of the press limit a level of performance at which the function of the knotter can generally be reliably achieved.
- the object of the invention is therefore to provide a baler in which the binding with binding material is to be applied even at high compressive forces with high reliability and high load capacity.
- this object is achieved by a baler according to the preamble of claim 1, starting with the characterizing features of claim 1.
- the tensile stresses for the execution of the first node and the execution of the second node may be in overlapping areas and accordingly adjusted uniformly. In the more general case, however, a different adjustment of the tensile stresses is provided.
- the tensile stresses on the mutual twine strands are specified differently, especially as the twine strand is loaded on the side opposite the knotter with a larger wrap around the bale and stronger feed movements.
- a corresponding tension control can be achieved in various ways, e.g. also via driven rollers with torque control.
- a simple and easy-to-control clamping device initially provides for a brake, in particular a friction brake, for the binding material and from there to the knotter a resiliently guided deflection loop.
- a stop limit can be provided for the movement of the deflection roller, in whose area a defined force is provided for the execution of the first node.
- One in the Fig. 1 to 3 the drawing as a whole with 1 designated channel baler comprises a filling chamber 2, which continues in plan view in a compression channel continuously and through which a ram 4 advances into the compression channel 3 and back moves back to the filling space 2 loosely thrown material to compress a bale 5 and 6, respectively.
- the bales 5, 6 are tied with binding material, so that after leaving the pressing channel 3 they retain their compact cuboidal shape.
- Several straps are provided parallel to each other to better hold the bale together. In the present case, a horizontal banding is shown, but in practice a vertical binding is also provided and, in particular with bales of critical cohesion, a criss-cross banding can also be established.
- the binding material forms an open loop, in which two strands 9, 10 run continuously through from a front side on the bale 5 to be strapped, two strands 9, 10 to a supply of binding material 11, 12, 13, 14, 15, 16, respectively ,
- the strands are initially 8.9 on teilfertig-finished bale 5, after which the strand 9 passes on the Knoterseite by the area of the knotter 7, while the strand 10 is located on the opposite side in the access of a Zuriosarms 17, the initiation of the knot by the plunger 4 passes through corresponding slots and the strand 10 also brings in the area of the knotter, as shown in Fig. 2 you can see.
- the knotter then executes two consecutive knots per loop, of which the first closes the binding of the bale 5 and the second - with the removal of the remaining strands 9, 10 behind the first knot - makes a new second starting knot for a loop which is a new one Bales can absorb.
- the two nodes to be produced in succession are indeed produced in Knoter 7 in the same way but under very different conditions.
- the first-made node is carried out at a binding tension, which is determined by the feed movement of the feed arm 17 and a tight plant on the high density bale 5 provides.
- the second node is a node in which, after separating the binding around the bale 5, the free ends of the binding material, as brought about by the binder stocks, are held together and knotted together. In general, the length and tension in the binder are yielded with the particular risk that inadequate stress leads to insufficiently consolidated nodes.
- each strand of the binder passes through one of six illustrated tensioning devices 18,19,20,21,22,23, which will be described in more detail below, including a yarn brake, as they are made Fig. 4 is illustrated.
- a binding stock 24 is shown as a simple binding spool to be unwound from within, from which a spun strand 9 passes through a thread brake 25.
- the yarn brake 25 allows the twine 9 initially pass through a guide eyelet 26 so that it passes in a predetermined direction under a shoe 27 which is pressed by a spring 28 on a bolt 29 with a predeterminable contact force to a counter-plate 30.
- a predetermined braking effect is achieved by friction with adjustable normal force to a yarn brake.
- the shoe 27 is bent up like a skid in order to avoid damage and entanglement of the twine 9.
- twine strand 9 runs in one of the clamping devices 18 to 23, for example, a in Fig. 5 to 8 illustrated tensioning device 18, with a resiliently guided Umlenkschleife 31 for the binding a.
- the tensioning device 18 comprises a vertical back plate 32 for mounting or welding on lateral outer walls of the baler 1, from which a bracket 33 protrudes horizontally.
- a bracket 33 protrudes horizontally.
- two guide rods 34,35 protrude parallel to each other down.
- These guide rods 34,35 are screwed at the upper end to the bracket 33 and also screwed together at the bottom for stiffening together with a yoke strut 36.
- roller forks 39,40 are mounted, in each case rotatably about a hinge 41,42 with a vertical axis.
- the Rollerigabein 39,40 each store a pulley 43 and 44 with a horizontal axis, so that over the pulleys 43,44 of the twine 9 can be performed down to a free roller 45 and from this back up in the course of a Umlenkschleife.
- the vertical hinges 41,42 are aligned with the vertical axis of rotation in each case on the circumference of the associated roller and thus allow a clean adjustment of the direction of movement of the spun strand when this-like Fig. 8 can be seen - in front of and behind the tensioning device 18 to take a different horizontal orientation.
- the free roller 45 can move up and down to shorten or widen the deflection loop 31. It is rotatably mounted in a roller fork 46 with a horizontal axis, which is fixed via a bolt 47 in the middle in a weight packet 48 with a plurality of superimposed plates 49.
- the plates 49 have for the passage of the guide rods 34,35 recesses, which ensure a lateral guidance, wherein one of the plates, here a lowermost plate 50, respectively a lower support surface for each one of two compression springs 51,52 forms, as coil springs the guide rods 34,35 enclose and upper side rest against the console 33.
- the free roller 45 is thus pulled in the sense of the effect of a clamping device for the Umlenkschleife 31 through the weight pack 48 down.
- the downwardly acting force of the compression springs 51,52 which is the greater, the further the deflection loop 31 is shortened and the further the compression of the springs together.
- the roller 45 comes into a stop position when the roller fork 46 is pulled up so that it strikes under the bracket 33, to which the roller fork 46 is bent on the upper side to wide stop plates 53,54.
- the function of the clamping device 18 with their different work areas different clamping force levels is particularly in comparison with the Fig. 2 clear.
- sludge must be withdrawn from the respective slug stock on both sides. This is the case, in particular for the respective twine on the opposite side of the knotter 7, but also applies to the twine on the side of the knotter.
- the Umschnürung For the production of the second node after separation of the finished Umschnürung is also sufficient to ensure tensile strength on both spun strands, even if the spun twine can be due to the resulting leadership of the strands quite a degree of length free.
- the Umlenkschleife 31 can significantly expand and receives despite extensive relaxation of the springs 51,52 with the weight package 48 a load that ensures the tension during knotting and ensures the strength of the knot.
- the clamping device 18 may be equipped with a breakage monitoring for the binding material.
- a proximity sensor 55 is provided which, for example as an inductive sensor, reports a fall in the weight packet 48 onto the yoke brace 36, via an arm 56 connected to the yoke brace 36.
- a tearing of the twine strand 9 between yarn brake 25 and Knoter leads to the fall of the weight packet 48 and thus to a message of the breakage of the tie through the proximity sensor 55.
- the case of the weight pact can also be monitored by a variety of other known sensors or switches.
- the roles 43,44 and 45 have a very important function for the feeding of the binding material, by making the transport of the binding material to the knotters frictionless. This is a supply without lots and unevenness, to achieve about in the form of slip-stick effects with the predetermined longitudinal stress in the binder.

Description
Die Erfindung betrifft eine Ballenpresse nach dem Oberbegriff des Anspruchs 1, wie sie aus der
Diese Umschnürung mit Bindegut hat bei fahrbaren Erntemaschinen ihrer eigene Tradition, wobei ein zentraler Antrieb von einer Zugmaschine aus und eine fortlaufende, stillstandsfreie Bewegung der Elemente der Presse ein Leistungsniveau begrenzen, bei dem die Funktion der Knoter im allgemeinen verläßlich erzielt werden kann.This necking with binding material has its own tradition with mobile harvesters, with central drive from a tractor and continuous, non-stationary movement of the elements of the press limit a level of performance at which the function of the knotter can generally be reliably achieved.
In der
Aufgabe der Erfindung ist es dementsprechend, eine Ballenpresse zu schaffen, bei der die Umschnürung mit Bindegut auch bei hohen Preßkräften mit hoher Zuverlässigkeit und hoher Belastbarkeit aufzubringen ist.The object of the invention is therefore to provide a baler in which the binding with binding material is to be applied even at high compressive forces with high reliability and high load capacity.
Gemäß der Erfindung wird diese Aufgabe von einer Ballenpresse nach dem Oberbegriff des Anspruchs 1 ausgehend mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.According to the invention, this object is achieved by a baler according to the preamble of
Es hat sich gezeigt, daß die Zuführung des Bindeguts bei der Ausführung der Knoten im Knoter einen wichtigen und kritischen Einfluß auf die Verknotung der Umschnürung hat und daß der Knoter nicht schon dann im Sinne höherer Anforderungen an Belastbarkeit und Zuverlässigkeit der Umschnürung brauchbar arbeitet, wenn das Bindegut nur mit irgendeiner Zugspannung zugeführt wird, die lediglich die vorgegebene Bindegutführung sichert, um Lose, Schleifen u. dgl. zu vermeiden. Vielmehr bedarf es einer Zugspannungsregelung, die bei dem jeweiligen Knoten einerseits gewährleistet, daß die knotenförmige Verschlingung einerseits vom Knoter ausführbar ist, andererseits aber auch eine Verfestigung im Knoter ergibt, bei der der nach der Freigabe hochbelastete Knoten nicht aufgeht. Diese besondere Vorgabe für den jeweils ersten der beiden auszuführenden Knoten, der die Umschnürung eines fertigen Ballens abschließt, ist nicht ohne weiteres bei dem nachfolgend auszuführenden zweiten Knoten übereinstimmend vorzugeben, der als Anfangsknoten für eine nachfolgende Bandschleife zunächst keine ballenseitige Belastung aufweist. Dafür benötigt der zweite Knoten nach dem Abtrennen des Bindeguts hinter dem ersten Knoten mit den Anfängen der Stränge einer neuen Bindegutschleife Zugspannungen auf beiden Strängen, die einerseits wieder die Durchführungen der Umschlingungen für den Knoten erlauben, andererseits dem Knoten trotz geringerer Belastung auch eine Festigkeit mitgeben, die ein Aufgehen des Knotens, insbesondere mit einem Durchziehen des einen oder anderen Strangendes ausschließt. Fallweise können die Zugspannungen für die Ausführung des ersten Knotens und die Ausführung des zweiten Knotens in einander überschneidenden Bereichen liegen und dementsprechend einheitlich eingestellt sein. Im allgemeineren Fall ist aber eine unterschiedliche Einstellung der Zugspannungen vorzusehen. Weiter sind die Zugspannungen auf den beiderseitigen Bindegutsträngen unterschiedlich vorgebbar, zumal der Bindegutstrang auf der dem Knoter gegenübergelegenen Seite mit einem größeren Umschlingungsanteil am Ballen und stärkeren Zuführbewegungen belastet ist.It has been shown that the supply of the binder in the execution of the nodes in Knoter has an important and critical influence on the knotting of the lashing and that the knotter is not already useful in terms of higher demands on resilience and reliability of the lashing useful if the Bindegut is supplied only with any tension that secures only the predetermined binding guide to lose, loops u. Like. To avoid. Rather, it requires a tension control, which ensures on the one hand on the one hand that the knot-shaped entanglement is on the one hand executable by the knotter, but on the other hand also results in a hardening in Knoter, in which the highly loaded after the release node does not work. This particular requirement for the respective first of the two nodes to be executed, which completes the binding of a finished bale, is not readily given in the second node to be subsequently executed, which initially has no ball-side loading as the starting node for a subsequent belt loop. For this purpose, the second node after the separation of the binder behind the first node with the beginnings of the strands of a new tie loop tensile stresses on both strands, on the one hand again allow the implementation of the wraps for the node, on the other hand give the node despite lower load and a strength, the one rising of the knot, in particular with a pulling through one or the other strand ends excludes. Occasionally, the tensile stresses for the execution of the first node and the execution of the second node may be in overlapping areas and accordingly adjusted uniformly. In the more general case, however, a different adjustment of the tensile stresses is provided. Next, the tensile stresses on the mutual twine strands are specified differently, especially as the twine strand is loaded on the side opposite the knotter with a larger wrap around the bale and stronger feed movements.
Eine entsprechende Zugspannungsregelung kann auf verschiedene Weise, z.B. auch über angetriebene Rollen mit Drehmomentenregelung erfolgen. Eine einfache und leicht zu beherrschende Spanneinrichtung sieht aber zunächst einmal eine Bremse, insbesondere eine Reibbremse, für das Bindegut und von dieser aus zum Knoter hin eine nachgiebig geführte Umlenkschleife vor. Um bei dieser eine vorgegebene Zugspannung für den ersten Knoten zu erzielen, kann für die Bewegung der Umlenkrolle eine Anschlagbegrenzung vorgesehen sein, in deren Bereich eine definierte Kraft zur Ausführung des ersten Knotens vorgesehen ist.A corresponding tension control can be achieved in various ways, e.g. also via driven rollers with torque control. However, a simple and easy-to-control clamping device initially provides for a brake, in particular a friction brake, for the binding material and from there to the knotter a resiliently guided deflection loop. In order to achieve a predetermined tensile stress for the first node in this, a stop limit can be provided for the movement of the deflection roller, in whose area a defined force is provided for the execution of the first node.

Die Ballen 5,6 werden mit Bindegut umschnürt, so daß sie nach dem Verlassen des Preßkanals 3 ihre kompakte quaderförmige Gestalt behalten. Dabei werden mehrere Umschnürungen parallel zueinander vorgesehen, um den Ballen damit besser zusammenzuhalten. Im vorliegenden Fall ist eine horizontale Umschnürung dargestellt, doch wird in der Praxis ebenso eine vertikale Umschnürung vorgesehen und insbesondere bei Ballen kritischen Zusammenhalts kann auch eine kreuzweise Umschnürung eingerichtet werden.The
Die Umschnürung erfolgt im vorliegenden Fall nicht, wie früher bei stationären hydraulischen Hochleistungs-Ballenpressen, mit Draht, der durch Verdrillen von Enden zu geschlossenen Umschnürungen zusammengefügt wird, sondern gemäß der
Vor dem Verknoten bildet das Bindegut eine offene Schleife, bei der von einem vorderseitig an dem zu umschnürenden Ballen 5 gelegenen Knoten 8 zwei Stränge 9,10 durchgehend zu einem jeweils auf beiden Seiten vorrätigen Bindegutvorrat 11,12,13,14,15,16 durchlaufen. Dabei liegen die Stränge 8,9 zunächst am teilfertigen Ballen 5 an, wonach der Strang 9 auf der Knoterseite durch den Bereich des Knoters 7 hindurchläuft, während der Strang 10 auf der gegenüberliegenden Seite im Zugriff eines Zuführarms 17 liegt, der zur Einleitung des Verknotens durch den Preßkolben 4 mit entsprechenden Schlitzen hindurchfährt und den Strang 10 gleichfalls in den Bereich des Knoters hineinbringt, wie dies in
Aus der Betrachtung dieses an sich herkömmlichen Umschnürungsvorgangs wird deutlich, daß die beiden aufeinanderfolgend herzustellenden Knoten zwar im Knoter 7 in der gleichen Weise aber unter sehr unterschiedlichen Bedingungen hergestellt werden. Der jeweils erstgefertigte Knoten erfolgt bei einer Bindegutspannung, die durch die Zuführbewegung des Zuführarms 17 bestimmt ist und eine straffe Anlage am hochverdichteten Ballen 5 vorsieht. Der zweite Knoten ist demgegenüber ein Knoten, bei dem nach Abtrennen der Umschnürung um den Ballen 5 die freien Enden des Bindeguts, wie es von den Bindegutvorraten herangeführt ist, zusammengehalten und gemeinsam verknotet werden. Dabei wird im allgemeinen Länge und Spannung im Bindegut nachgegeben mit der besonderen Gefahr, daß unzulängliche Spannung zu nicht ausreichend verfestigten Knoten führt.From the consideration of this per se conventional Umschnürungsvorgangs it becomes clear that the two nodes to be produced in succession are indeed produced in
Wie insbesondere aus den
In
Von dort läuft der Bindegutstrang 9 in eine der Spanneinrichtungen 18 bis 23, beispielsweise eine in
Die Spanneinrichtung 18 umfaßt eine vertikale Rückenplatte 32 zum Anmontieren oder Anschweißen an seitlichen Außenwänden der Ballenpresse 1, von der eine Konsole 33 horizontal vorsteht. Von der Konsole 33 mit nach unten offenem U-Querschnitt ragen zwei Führungsstangen 34,35 parallel zueinander nach unten. Diese Führungsstangen 34,35 sind am oberen Ende an der Konsole 33 festgeschraubt und am unteren Ende ebenfalls zur Versteifung gemeinsam mit einer Jochstrebe 36 verschraubt.The
Auf die Konsole 33 ist nach oben hinausragend ein Ständer 37 mit einer horizontal vorstehenden Kragplatte 38 fest angebracht, unter der im Abstand voneinander zwei Rollengabeln 39,40 angebracht sind und zwar jeweils drehbeweglich um ein Gelenk 41,42 mit vertikaler Achse. Die Rollerigabein 39,40 lagern jeweils eine Umlenkrolle 43 bzw. 44 mit horizontaler Achse, so daß über die Umlenkrollen 43,44 der Bindegutstrang 9 nach unten zu einer freien Laufrolle 45 und von dieser wieder nach oben im Zuge einer Umlenkschleife geführt werden kann. Die vertikalen Drehgelenke 41,42 sind mit der vertikalen Drehachse jeweils auf den Umfang der zugehörigen Laufrolle ausgerichtet und erlauben damit eine saubere Einstellung der Laufrichtung auf den Bindegutstrang wenn dieser-wie aus
Die freie Laufrolle 45 kann sich zur Verkürzung oder Ausweitung der Umlenkschleife 31 aufwärts und abwärts bewegen. Sie ist in einer Rollengabel 46 mit horizontaler Achse drehbar gelagert, die über einen Schraubbolzen 47 mittig in einem Gewichtspaket 48 mit mehreren übereinanderliegenden Platten 49 festgelegt ist. Die Platten 49 weisen für den Durchtritt der Führungsstangen 34,35 Aussparungen auf, die eine seitliche Führung sicherstellen, wobei eine der Platten, hier eine unterste Platte 50, jeweils eine untere Abstützfläche für jeweils eine von zwei Druckfedern 51,52 bildet, die als Schraubenfedern die Führungsstangen 34,35 umschließen und oberseitig gegen die Konsole 33 anliegen.The free roller 45 can move up and down to shorten or widen the
Die freie Laufrolle 45 wird also im Sinne der Wirkung einer Spanneinrichtung für die Umlenkschleife 31 durch das Gewichtspaket 48 nach unten gezogen. Darüber hinaus wirkt auf das Gewichtspaket und damit mittelbar auch auf die Laufrolle 45 die nach unten wirkende Kraft der Druckfedern 51,52, die um so größer wird, je weiter sich die Umlenkschleife 31 verkürzt und je weiter sich damit die Druckfedern zusammendrücken. Schließlich gelangt die Laufrolle 45 in eine Anschlagstellung, wenn die Rollengabel 46 so hochgezogen wird, daß sie unter die Konsole 33 anschlägt, wozu die Rollengabel 46 oberseitig zu breiten Anschlagplatten 53,54 abgewinkelt ist.The free roller 45 is thus pulled in the sense of the effect of a clamping device for the
Die Funktion der Spanneinrichtung 18 mit ihren verschiedenen Arbeitsbereichen unterschiedlichen Spannkraftniveaus wird insbesondere im Vergleich mit der
Für den Abzug von Bindegut aus dem Bindegutvorrat ist auf den jeweiligen Strang eine Zugkraft aufzubringen, die die Fadenbremse 25 überwindet. Dabei verkürzt sich die Umlenkschleife 31 infolge der hohen Zugkräfte, wobei die Druckfedern 51,52 entsprechend zusammengedrückt werden und die Rollengabel 46 sogar zum Anschlag gegen die Konsole 33 kommen kann.For the withdrawal of binder from the binder stock is to apply a tensile force on the respective strand, which overcomes the
Auch nach dem Abschluß und Stillstand des Holvorgangs für Bindegut geht von der kurzen Umlenkschleife 31 und den stark zusammengedrückten Druckfedern 51,52 eine hohe Zugkraft aus, die den jeweiligen Bindegutstrang unter hoher Zugkraft hält. Von diesem Zugkraftniveau aus wird der erste Knoten zwischen den Bindegutsträngen ausgeführt, der einen festen Abschluß der Umschnürung für den fertiggestellten Ballen liefert.Even after the completion and stoppage of the Holengangs for binding goes from the short Umlenkschleife 31 and the strongly
Für die Fertigung des zweiten Knotens nach Abtrennen der fertigen Umschnürung ist gleichfalls eine ausreichende Zugkraft auf beiden Bindegutsträngen sicherzustellen, auch wenn die Bindegutstränge aufgrund der sich ergebenden Führung der Stränge durchaus ein gewisses Maß an Länge frei werden läßt. In diesem Fall kann sich die Umlenkschleife 31 erheblich ausdehnen und erhält trotz weitgehender Entspannung der Druckfedern 51,52 mit dem Gewichtspaket 48 eine Belastung, die die Zugspannung beim Verknoten gewährleistet und die Festigkeit der Verknotung sicherstellt.For the production of the second node after separation of the finished Umschnürung is also sufficient to ensure tensile strength on both spun strands, even if the spun twine can be due to the resulting leadership of the strands quite a degree of length free. In this case, the
Wie insbesondere in den
Die Kombination von Gewichts- und Federkräften zur Einstellung der verschiedenen Anforderungen an die Zugkraft im Bindegut hat sich als besonders vorteilhaft herausgestellt. Es versteht sich allerdings, daß die jeweiligen Kräftebereiche für die Umlenkschleife 31 in verschiedenen Ausdehnungslängen bzw. Laufrollen-Positionen auch in anderer Weise, etwa ganz mit Hilfe bereichsweise arbeitender Federn oder sogar mit Hilfe druckmittelbetätigter Stellglieder erreicht werden könnte.The combination of weight and spring forces to adjust the various requirements of the tensile force in the binding material has proven to be particularly advantageous. It is understood, however, that the respective areas of force for the
Die Rollen 43,44 und 45 haben für die Zuführung des Bindeguts eine sehr wichtige Funktion, indem sie den Transport des Bindeguts zu den Knotern hin reibungsarm gestalten. Damit ist eine Zuführung ohne Lose und Ungleichmäßigkeiten, etwa in Form von slip-stick-Effekten mit der vorgegebenen Längsspannung im Bindegut zu erreichen.The
Bei der Einstellung der Spanneinrichtungen wird dem Bindegutstrang 10 auf der dem Knoter 7 gegenüberliegenden Seite des Ballens regelmäßig eine höhere Zugspannung zugeordnet werden. Dies erfolgt dann im allgemeinen nicht nur durch eine höhere Bremskrafteinstellung an der Bindegutbremse 25, sondern vor allem auch durch eine Auslegung der Federn und Federwege im Arbeitsbereich nahe der Anschlagstellung mit den Anschlagplatten 53 und 54.When setting the tensioning devices, a higher tensile stress is regularly associated with the
