Description

Die Erfindung bezieht sich auf eine Ballenpresse nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a baling press according to the preamble of patent claim 1.

Eine derartige Ballenpresse ist beispielsweise in der EP 3 199 331 A1 beschrieben.Such a baler is, for example, in EP 3 199 331 A1 described.

An der seitlichen Außenwand des Ballenpressengehäuses ist dabei eine Verpackungseinrichtung verfahrbar angeordnet, in die eine Vielzahl von Gut, das von dem Pressstempel verdichtet und in dem Pressraum eingefüllt ist, soll an einer möglichst beliebigen Position des Pressstempels mit dem Draht umreift werden.On the lateral outer wall of the baling press housing, a packaging device is arranged such that it can be moved, in which a large number of items that are compacted by the press ram and filled into the press chamber are to be strapped with the wire at any desired position of the press ram.

Durch die DE 19 36 493 A1 , DE 1 276 541 B sowie die CN 208559842 U sind ebenfalls solche Ballenpressen bekannt geworden, durch die Ballen aus losem Abfallmaterial hergestellt und mit mindestens einer Drahtschlinge umreift sind. Der vereinzelte Draht ist in einem Magazin gelagert und kann aus diesem im Bedarfsfall entnommen sein. Der Draht wird oftmals manuell in den Pressraum eingeschoben und in Führungskanälen um den Ballen gelegt. Das Dokument DE 19 36 493 A1 offenbart eine Ballenpresse nach dem Oberbegriff des Anspruchs 1.through the DE 19 36 493 A1 , DE 1 276 541 B as well as the CN 208559842 U such balers have also become known, are made by the bales of loose waste material and strapped with at least one wire loop. The separated wire is stored in a magazine and can be removed from it if necessary. The wire is often pushed manually into the baling chamber and placed around the bale in guide channels. The document DE 19 36 493 A1 discloses a baler according to the preamble of claim 1.

Der Draht ist auf einer Rolle aufgewickelt und eine Drahtschlaufe befindet sich permanent zwischen der Innenwand des Ballenpressengehäuses und dem eingepressten Gut, sodass der Draht zunächst durch die Hubbewegungen des Pressstempels in den Pressraum eingeschoben ist und an drei Seiten des Ballens anliegt. Sobald der Pressvorgang beendet ist, d. h., dass das zu verpressende Gut eine entsprechend groß bemessene Außenkontur aufweist, wird das Drahtende mittels der Verpackungseinrichtung in den Pressstempel eingeschoben und dort verknotet. Wenn die beiden freien Enden des Drahtes zu der Drahtschlinge verbunden sind, kann der derart umreifte Ballen aus dem Pressraum durch Öffnen der Türe entnommen werden.The wire is wound on a roll and a wire loop is permanently located between the inner wall of the baler housing and the pressed material, so that the wire is initially pushed into the baling chamber by the lifting movements of the press ram and is in contact with three sides of the bale. As soon as the pressing process is complete, ie the material to be pressed has a corresponding has a large outer contour, the end of the wire is pushed into the ram by means of the packaging device and knotted there. When the two free ends of the wire are connected to form the wire loop, the bale strapped in this way can be removed from the baling chamber by opening the door.

Eine solche Ballenpresse hat sich in der Praxis zwar bewährt, jedoch ist die Handhabung der Drahtrollen oftmals schwierig oder umständlich, da diese eine Eigengewichtskraft von mehreren Dutzend Kilogramm aufweisen. Zudem sind solche Drahtrollen permanent auszutauschen. Solche Nachrüstarbeiten sind zeitaufwendig und bedürfen Fachkenntnissen, um die entsprechende Anordnung der abstehenden Drähte in Bezug auf die Verpackungseinrichtung und den in dem Ballenpressengehäuse vorgesehenen Führungskanälen zur Aufnahme der Drähte zu erreichen. Darüber hinaus stehen die seitlich angeordneten Drahtrollen über den Außenumfang der Ballenpresse hinaus, sodass der von der Ballenpresse benötigte Bauraum vergrößert ist. Dies behindert jedoch die Bewegung im Bereich der Ballenpresse, beispielsweise durch Transportvorgänge der Gabelstapler.Although such a baling press has proven itself in practice, the handling of the wire rolls is often difficult or cumbersome, since they have a weight of several dozen kilograms. In addition, such wire rolls permanently exchanged. Such retrofit work is time consuming and requires skill to achieve the proper placement of the protruding wires in relation to the wrapping equipment and the guide channels provided in the baler housing to accommodate the wires. In addition, the laterally arranged wire rolls protrude beyond the outer circumference of the baling press, so that the installation space required by the baling press is increased. However, this hinders movement in the area of the baler, for example due to transport operations by forklifts.

Es ist daher Aufgabe der Erfindung, eine Ballenpresse der eingangs genannten Gattung derart weiterzubilden, dass der für die Umreifung des verpressten Ballens erforderliche Draht möglichst einfach, unkompliziert und zeitsparend in das Ballenpressengehäuse und den Pressstempel eingeführt werden kann. Der Draht soll in das Ballenpressengehäuse und den Pressstempels manuell, semiautomatisch oder vollautomatisch einführbar sein. Darüber hinaus soll eine Verpackungseinrichtung für diese Arbeitsvorgänge zur Verfügung stehen, die als modularer und nachrüstbarer Bausatz an bestehenden Ballenpressen anbringbar ist.It is therefore the object of the invention to develop a baler of the aforementioned type in such a way that the wire required for strapping the compressed bale can be inserted into the baler housing and the press ram as simply, easily and quickly as possible. The wire should be able to be inserted into the baler housing and the press ram manually, semi-automatically or fully automatically. In addition, a packaging device should be available for these work processes, which can be attached to existing baling presses as a modular and retrofittable kit.

Diese Aufgaben sind erfindungsgemäß durch die Merkmale des kennzeichnenden Teils von Patentanspruch 1 .These objects are achieved according to the invention by the features of the characterizing part of patent claim 1 .

Weitere vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous developments of the invention result from the dependent claims.

Dadurch, dass zur Einführung des Drahtes mittels der Verpackungseinrichtung in das Innere des Ballenpressengehäuses und den Pressstempel eine Verpackungseinrichtung vorgesehen ist, und dass der Draht durch mindestens eine in die Tür eingearbeitete Öffnung in das Ballenpressengehäuse eingeschoben und aus diesem herausgeführt ist, soll eine möglichst einfache und unkomplizierte Handhabung von vereinzelten Drähten zur Umreifung von Ballen zur Verfügung gestellt sein.The fact that a packaging device is provided for inserting the wire by means of the packaging device into the interior of the baling press housing and the press ram, and that the wire is inserted into the baling press housing through at least one opening in the door and guided out of it, should be as simple and uncomplicated handling of individual wires for strapping bales.

Wenn die Verpackungseinrichtung aus einer Antriebseinheit und/oder einer Zugeinheit besteht, können die beiden freien Enden des Drahtes vorteilhafter Weise unabhängig voneinander in das Ballenpressengehäuse bzw. den Pressstempel eingeschoben und/oder herausgezogen werden. Demnach bewegt die Antriebseinheit das erste freie Ende des Drahtes in das Ballenpressengehäuse und nachfolgend in den in der Pressstempel eingearbeiteten Führungskanal und sobald dieses erste freie Ende des Drahtes aus der in der Tür eingearbeiteten Öffnung heraustritt, nimmt die Zugeinheit dieses auf, sodass der Draht durch die Zugeinheit gestrafft um das eingepresste Gut bzw. den im Pressraum angeordneten Ballen gezogen werden kann. Selbstverständlich können die Antriebseinheit und die Zugeinheit unabhängig voneinander oder gemeinsam vorgesehen und betrieben sein.If the packaging device consists of a drive unit and/or a traction unit, the two free ends of the wire can advantageously be independent are pushed into and/or pulled out of one another in the baling press housing or the press ram. Accordingly, the drive unit moves the first free end of the wire into the baler housing and then into the guide channel incorporated in the press ram and as soon as this first free end of the wire emerges from the opening incorporated in the door, the pulling unit picks it up so that the wire passes through the Pulling unit can be tightened around the pressed material or the bales arranged in the pressing chamber. Of course, the drive unit and the traction unit can be provided and operated independently of one another or together.

Darüber hinaus können vorteilhafter Weise die beiden an der Außenseite der Tür verlaufenden freien Enden des Drahtes durch die Antriebseinheit und/oder die Zugeinheit miteinander verbunden werden, sodass der Ballen durch die Drahtschlinge umreift ist. Sobald der Pressstempel in seine Ausgangsposition zurückgezogen wird, drückt das den Ballen bildende Gut die Drahtschlinge auseinander, wodurch zwischen diesem und dem verpressten Gut ein Kräftegleichgewicht entsteht.In addition, the two free ends of the wire running on the outside of the door can advantageously be connected to one another by the drive unit and/or the pulling unit, so that the bale is strapped by the wire loop. As soon as the press ram is pulled back into its starting position, the material forming the bale pushes the wire loop apart, as a result of which an equilibrium of forces arises between this and the pressed material.

Vorteilhafterweise können in die Tür mehrere Öffnungen eingearbeitet bzw. vorgesehen sein, um den Ballen mit mehreren solcher Drahtschlingen zu umreifen. Die jeweilige Antriebseinheit und die Zugeinheit an der Verpackungseinrichtung können dabei jeweils an einer Führungsstange axial beweglich gelagert sein, sodass die Antriebseinheit und die Zugeinheit jeweils fluchtend zu einer der Öffnungen der Tür angeordnet werden können.Advantageously, several openings can be incorporated or provided in the door in order to strap the bale with several such wire loops. The respective drive unit and the traction unit on the packaging device can each be mounted so that they can move axially on a guide rod, so that the drive unit and the traction unit can each be arranged in alignment with one of the openings in the door.

Eine vollautomatische Einführung des Drahtes in das Ballenpressengehäuse und den Führungskanal des Pressstempels erfolgt mit Hilfe eines Magazins in Form einer Trommel, in der eine Vielzahl von vereinzelten Drähten angeordnet sind. Die Trommel ist dabei auf der Oberseite des Ballenpressengehäuses in einem geneigten Winkel angeordnet, um die Bauhöhe der Ballenpresse zu reduzieren. Aufgrund dieser geneigten Ausrichtung der Trommel rutschen die vereinzelten Drähte in Richtung der Austrittsöffnung der Trommel. In diesem Bereich ist die Antriebseinheit vorgesehen, die den jeweils austretenden Draht aufnimmt und in das Ballenpressengehäuse einschiebt.A fully automatic introduction of the wire into the baling press housing and the guide channel of the press ram takes place with the help of a magazine in the form of a drum, in which a large number of individual wires are arranged. The drum is arranged at an inclined angle on the top of the baler housing in order to reduce the overall height of the baler. Due to this inclined orientation of the drum, the individual wires slide in the direction of the outlet opening of the drum. The drive unit is provided in this area, which picks up the emerging wire and pushes it into the baler housing.

Die Trommel ist um ihre Längsachse drehbar gelagert, sodass der jeweilige in der Trommel vorgesehene Schacht zur Aufnahme des Drahtes exakt positioniert zu der Antriebseinheit ausgerichtet werden kann. Die Befüllung der Trommel ist einfach und zeitsparend zu bewerkstelligen, denn die vereinzelten Drähte können in den jeweiligen leeren Schacht der Trommel eingeschoben werden. Die Eigengewichtkraft solcher vereinzelten Drähte ist gegenüber einem Endlosdraht, aufgewickelt auf eine Rolle, sehr gering.The drum is rotatably mounted about its longitudinal axis, so that the respective shaft provided in the drum for receiving the wire can be positioned exactly aligned with the drive unit. The filling of the drum is easy and time-saving because the individual wires can be pushed into the respective empty shaft of the drum. The dead weight of such individual wires is very low compared to an endless wire wound on a roll.

Folglich kann jeder Kunde aus drei Bedienmöglichkeiten zur Bestückung der Ballenpresse mit einem Draht aus einer vorgegebenen Länge auswählen. Zum einen kann nämlich der vereinzelte Draht manuell in das Ballenpressengehäuse eingeschoben und aus diesem herausgezogen werden, der Einschubvorgang des vereinzelten Drahtes erfolgt semiautomatisch mithilfe der Antriebseinheit und das Straffen des Drahtes kann durch die Zugeinheit bewerkstelligt sein oder die Bestückung des Ballenpressengehäuses und des Pressstempels mit dem eingeschobenen Draht erfolgt vollautomatisch, wenn nämlich der vereinzelte Draht in einem Magazin in Form der Trommel gelagert und zur Verfügung gestellt ist.As a result, each customer can choose from three operating options for loading the baler with a wire of a specified length. On the one hand, the separated wire can be manually inserted into the baling press housing and pulled out of it, the insertion process of the separated wire takes place semi-automatically with the help of the drive unit and the wire can be tightened by the pulling unit or by loading the baling press housing and the press ram with the inserted wire Wire takes place fully automatically, namely when the separated wire is stored and made available in a magazine in the form of a drum.

Zudem ist eine solche Verpackungseinrichtung als nachrüstbarer und modularer Bausatz anbringbar. Lediglich die Tür der Ballenpresse ist auszutauschen, um die in der Tür erforderlichen Öffnungen zu erhalten.In addition, such a packaging device can be attached as a retrofittable and modular kit. Only the door of the baler needs to be replaced to get the openings required in the door.

In Figur 1 ist schematisch eine Ballenpresse 1 zur Verdichtung von Gut 2, insbesondere von Abfallmaterial aus Karton, Laub oder Gras zu einem mit mindestens einer Drahtschlinge 7 umreiften Ballen 3 zu entnehmen. Dabei umfasst die Ballenpresse 1 ein Ballenpressengehäuse 8, das eine quaderförmige Innenkontur aufweist. In dem Ballenpressengehäuse 8 ist eine Öffnung 13 vorgesehen, durch die das Gut 2 einführbar ist, sodass dieses in das Ballenpressengehäuse 8 gelangt.In figure 1 shows schematically a baling press 1 for compacting material 2, in particular waste material made of cardboard, leaves or grass, into a bale 3 strapped with at least one wire loop 7. The baler 1 comprises a baler housing 8, which has a cuboid inner contour. An opening 13 is provided in the bale press housing 8 through which the material 2 can be inserted so that it enters the bale press housing 8 .

Benachbart zu der Öffnung 13 ist in dem Ballenpressengehäuse 8 ein Presstempel 10 vorgesehen, der in üblicher Art und Weise axial beweglich ist und folglich eine Presskraft auf das eingefüllte Gut 2 ausübt, sodass dieses zu dem Ballen 3 verdichtet ist. Dabei wird das Gut 2 in einen Pressraum 9 eingeschoben und dort verdichtet, da der Pressraum 9 durch das Ballenpressengehäuse 8, den Pressstempels 10 sowie einer dem Pressstempel 10 gegenüberliegenden Tür 11 verschlossen ist. Die durch den Pressstempel 10 ausgeübte Presskraft wirkt demnach in die Pressrichtung 4, die senkrecht zu der Tür 11 verläuft.A press ram 10 is provided in the baler housing 8 adjacent to the opening 13 , which is axially movable in the usual manner and consequently exerts a pressing force on the filled material 2 , so that the latter is compressed into the bale 3 . The material 2 is pushed into a press chamber 9 and compressed there, since the press chamber 9 is closed by the baler housing 8 , the press ram 10 and a door 11 opposite the press ram 10 . The pressing force exerted by the ram 10 accordingly acts in the pressing direction 4 , which runs perpendicularly to the door 11 .

Sobald das Gut 2 zu dem Ballen 3 verdichtet ist, wird ein Draht 6 in das Ballenpressengehäuse 8 und den Pressstempel 10 eingeschoben. Um die Führung des Drahtes 6, insbesondere in den Eckbereichen zu erleichtern, ist in dem Ballenpressengehäuse 8 und dem Pressstempel 10 jeweils ein Führungskanal 14 vorgesehen, der im Wesentlichen eine U-förmige oder schwalbenschwanzförmige Innenkontur aufweist. Gemäß Figur 4 ist der Führungskanal 14 benachbart zu dem Ballen 3 offen, sodass sich der eingeschobene Draht 6 zu der Drahtschlinge 7 straffen lässt, um das verpresste Gut 2 dauerhaft in der vorgegebenen Form des Pressraums 9 zu halten. Wenn der Ballen 3 mit einem oder mehreren der Drahtschlingen 7 umreift ist und somit eine transportierbare Struktur aufweist, kann der Ballen 3 aus dem Pressraum 9 durch die Öffnung, die von der Tür 11 freigegeben ist, entnommen werden.As soon as the material 2 has been compacted into the bale 3 , a wire 6 is inserted into the bale press housing 8 and the ram 10 . In order to facilitate the guidance of the wire 6, particularly in the corner areas, a guide channel 14 is provided in the baler housing 8 and the press ram 10, which essentially has a U-shaped or dovetail-shaped inner contour. According to figure 4 the guide channel 14 is open adjacent to the bale 3 so that the inserted wire 6 can be tightened to form the wire loop 7 in order to keep the compressed material 2 permanently in the predetermined shape of the compression chamber 9 . When the bale 3 is strapped with one or more of the wire loops 7 and thus has a transportable structure, the bale 3 can be removed from the baling chamber 9 through the opening which is uncovered by the door 11 .

In Figur 2 ist eine Verpackungseinrichtung 21 abgebildet, durch die der vereinzelte Draht 6, der eine vorgegebene Länge von beispielsweise 4,2 Metern aufweist, in das Ballenpressengehäuse 8 und den Pressstempel 10 bewegt ist und um den Ballen 3 zur Bildung der Drahtschlinge 7 gestrafft ist. Dabei umfasst die Verpackungseinrichtung 21 eine Antriebseinheit 23 und eine Zugeinheit 24, die an der Außenseite der Tür 11 befestigt sind. Die Antriebseinheit 23 besteht dabei aus einem Motor und zwei beabstandet zueinander angeordnete Antriebsrollen 25, zwischen denen der Draht 6 eingeführt ist.In figure 2 a packaging device 21 is shown, through which the separated wire 6, which has a predetermined length of, for example, 4.2 meters, is moved into the bale press housing 8 and the ram 10 and tightened around the bale 3 to form the wire loop 7. The packaging device 21 includes a drive unit 23 and a pulling unit 24 which are attached to the outside of the door 11 . The drive unit 23 consists of one motor and two mutually spaced drive rollers 25, between which the wire 6 is inserted.

Das erste freie Ende des Drahtes 6 ist dabei mit der Bezugsziffer 12' und das gegenüberliegende zweite freie Ende des Drahtes 6 mit der Bezugsziffer 12" gekennzeichnet. Da die beiden Antriebsrollen 25 ein Drehmoment auf den Draht 6 ausüben, wird dieser in die Führungskanäle 14, die in dem Ballenpressengehäuse 8 und dem Pressstempels 14 vorgesehen sind, eingeschoben und so lange bewegt, bis das erste freie Ende 12' des Drahtes 6 aus dem Ballenpressengehäuse 8 im Bereich der Tür 11 austritt.The first free end of the wire 6 is marked with the reference number 12' and the opposite second free end of the wire 6 with the reference number 12". Since the two drive rollers 25 exert a torque on the wire 6, this is guided into the guide channels 14, which are provided in the baler housing 8 and the press ram 14, is inserted and moved until the first free end 12' of the wire 6 emerges from the baler housing 8 in the area of the door 11.

Die Verpackungseinrichtung 21 kann sowohl die Antriebseinheit 23 als auch die Zugeinheit 24 umfassen oder lediglich eine der beiden Bestandteile. Dies liegt im gewünschten Bedienablauf, um den Draht 6 einzuschieben, zu straffen bzw. die Drahtschlinge 7 zu bilden.The packaging device 21 can include both the drive unit 23 and the traction unit 24 or only one of the two components. This is part of the desired operating sequence in order to insert and tighten the wire 6 or to form the wire loop 7 .

Um den Einfädel- und Herausnahmevorgang des Drahtes 6 im Bereich der Tür 11 zu erreichen, sind in diese vier schlitzartige Öffnungen 22 eingearbeitet, die jeweils mit einem Anfang und einem Ende der Führungskanäle 14 des Ballenpressengehäuses 8 fluchtend gegenüberliegen, sodass das erste freie Ende 12' des Drahtes 6 durch die jeweilige Öffnung 22 der Tür 11 in den entsprechenden Führungskanal 14 durch die Antriebsrollen 25 der Antriebseinheit 23 eingeschoben ist.In order to achieve the threading and removal process of the wire 6 in the area of the door 11, four slot-like openings 22 are worked into this, which are aligned opposite one another with a beginning and an end of the guide channels 14 of the baler housing 8, so that the first free end 12' of the wire 6 is inserted through the respective opening 22 of the door 11 into the corresponding guide channel 14 by the drive rollers 25 of the drive unit 23.

Sobald das erste freie Ende 12' des Drahtes 6 aus der Öffnung 22 der Tür 11 herausgedrückt ist, wird dieses von der Zugeinheit 24 aufgenommen und mit dieser gekoppelt. Die Zugeinheit 24 ist dabei beispielsweise als Gewindespindel ausgestaltet, sodass eine Zug- und Rotationskraft auf das erste freie Ende 12' des Drahtes 6 einwirkt, wodurch der Draht 6 um den Ballen 3 gestrafft ist. Das zweite freie Ende 12" des Drahtes 6 wird währenddessen von der Antriebseinheit 23 gehalten, sodass dieses festgesetzt ist und sich nicht in Richtung des Ballengehäuses 8 bewegt. Folglich nähern sich die beiden freien Enden 12' und 12" des Drahtes 6 durch die Zugkraft der Zugeinheit 24 an und können miteinander verbunden werden.As soon as the first free end 12' of the wire 6 has been pushed out of the opening 22 of the door 11, it is picked up by the traction unit 24 and coupled to it. The pulling unit 24 is designed as a threaded spindle, for example, so that a pulling and rotational force acts on the first free end 12 ′ of the wire 6 , as a result of which the wire 6 is tightened around the bale 3 . Meanwhile, the second free end 12" of the wire 6 is held by the drive unit 23 so that it is fixed and does not move in the direction of the bale housing 8. Consequently, the two free ends 12' and 12" of the wire 6 approach each other due to the pulling force of the Train unit 24 and can be connected to each other.

Sobald die beiden freien Enden 12' und 12" des Drahtes 6 miteinander fixiert sind, kann der Pressstempel 10 aus dem Pressraum 9 herausgefahren werden, wodurch die von diesem ausgeübte Presskraft verloren geht und sich dafür das Gut 2 entgegen der Presserichtung 4 ausdehnt. Demnach ist die Drahtschlinge 7 durch die nach außen wirkenden Verformungskräfte des Gutes 2 weiter gestrafft und der Ballen 3 ist dadurch in seiner vorgegebenen Form durch die Drahtschlinge 7 fixiert.As soon as the two free ends 12′ and 12″ of the wire 6 are fixed to one another, the pressing ram 10 can be moved out of the pressing chamber 9, as a result of which the pressing force exerted by it is lost and the material 2 expands in the opposite direction to the pressing direction 4 the wire loop 7 is further tightened by the outwardly acting deformation forces of the item 2 and the bale 3 is thus fixed in its predetermined shape by the wire loop 7 .

Um lediglich eine Antriebseinheit 23 und eine Zugeinheit 24 für jede der vorhandenen Öffnungen 22 verwenden zu können, ist an der Außenseite der Türe 11 eine Führungsstange 15 für die Antriebseinheit 23 und für die Zugeinheit 24 vorgesehen. Die Antriebseinheit 23 und die Zugeinheit 24 sind axial beweglich an der jeweiligen Führungsstange 15 verschiebbar gelagert, sodass die Antriebseinheit 23 und die Zugeinheit 24 fluchtend zu der jeweiligen Öffnung 22 positionierbar sind.In order to be able to use only one drive unit 23 and one traction unit 24 for each of the existing openings 22 , a guide rod 15 for the drive unit 23 and for the traction unit 24 is provided on the outside of the door 11 . The drive unit 23 and the pulling unit 24 are mounted in an axially movable manner on the respective guide rod 15 so that the drive unit 23 and the pulling unit 24 can be positioned in alignment with the respective opening 22 .

Bei der ersten Ausführungsvariante der Figuren 1, 2 und 3 handelt es sich im Wesentlichen um eine semiautomatische Einführung und Verbindung des Drahtes 6 zu der Drahtschlinge 7, denn der vereinzelte Draht 6 ist zunächst in die Antriebseinheit 23 manuell einzusetzen und erst anschließend erfolgt der Einschubvorgang und die Verbindung der beiden freien Enden 12' und 12" des Drahtes 6 zu der Drahtschlinge 7 automatisch.In the first embodiment of the figures 1 , 2 and 3 It is essentially a semi-automatic introduction and connection of the wire 6 to the wire loop 7, because the separated wire 6 must first be inserted manually into the drive unit 23 and only then does the insertion process and the connection of the two free ends 12' and 12'' take place. the wire 6 to the wire loop 7 automatically.

In den Figuren 5 bis 7 ist die Ballenpresse 1 mit einer vollautomatischen Verpackungseinrichtung 21 ausgerüstet. Die vereinzelten Drähte 6 sind nämlich in einem Magazin in Form einer Trommel 26 gelagert. In die Trommel 26 sind eine Vielzahl von länglichen Schächten 27 eingearbeitet, in der der jeweilige Draht 6 angeordnet ist. Die Trommel 26 ist an der Oberseite des Ballenpressengehäuses 8 in einem vorgegebenen Winkel α von beispielsweise 30 Grad angeordnet, um die Bauhöhe der Ballenpresse 1 möglichst gering zu halten.In the Figures 5 to 7 the baling press 1 is equipped with a fully automatic packaging device 21. This is because the separated wires 6 are stored in a magazine in the form of a drum 26 . A plurality of elongated shafts 27 are incorporated into the drum 26, in which the respective wire 6 is arranged. The drum 26 is arranged on the upper side of the baler housing 8 at a predetermined angle α of 30 degrees, for example, in order to keep the overall height of the baler 1 as low as possible.

Gemäß Figur 6 ist die Trommel 26 um ihre Längsachse drehbar gelagert, sodass jeder der in der Trommel 26 vorgesehene Schacht 27 fluchtend zu der Antriebseinheit 23 ausgerichtet werden kann. Die Antriebseinheit 23 entnimmt dem Schacht 27 den dort angeordneten Draht 6 und transportiert das erste freie Ende 12' des Drahtes 6 in die jeweiligen Führungskanäle 14 des Ballenpressengehäuses 8 bzw. des Pressstempels 10 -wie vorstehend erläutert. Sobald das erste freie 12' des Drahtes 6 aus dem Ballenpressengehäuse 8 aufgeschoben ist, wird dieses von der Zugeinheit 24 aufgenommen und in Richtung des zweiten freien Endes 12", das an der Antriebseinheit 23 gehalten ist, bewegt, sodass die beiden freien Enden 12' und 12" verknotet bzw. miteinander fixiert werden können.According to figure 6 the drum 26 is rotatably mounted about its longitudinal axis, so that each shaft 27 provided in the drum 26 can be aligned with the drive unit 23 . The drive unit 23 removes the wire 6 arranged there from the shaft 27 and transports the first free end 12 ′ of the wire 6 into the respective guide channels 14 of the baler housing 8 or of the Press ram 10 -as explained above. As soon as the first free 12' of the wire 6 has been pushed out of the baler housing 8, it is picked up by the traction unit 24 and moved in the direction of the second free end 12'', which is held on the drive unit 23, so that the two free ends 12' and 12" can be knotted or fixed together.

Die Antriebseinheit 23 und die Zugeinheit 24 befinden sich vorteilhafter Weise auf der Oberseite des Ballenpressengehäuses 8, also zwischen dem Ballenpressengehäuse 8 und der Trommel 26. Gleichwohl werden die ersten freien Enden 12' des Drahtes 6 durch die Öffnungen 22 der Tür 11 eingeführt; beim Austreten des ersten freien Endes12' sind diese allerdings auf der Oberseite des Ballenpressengehäuses 8 angeordnet.The drive unit 23 and the traction unit 24 are advantageously located on top of the baler housing 8, i.e. between the baler housing 8 and the drum 26. However, the first free ends 12' of the wire 6 are inserted through the openings 22 of the door 11; when the first free end 12 ′ emerges, however, these are arranged on the upper side of the baler housing 8 .

In Figur 7 ist die Drehbewegung der Trommel 26 und die Positionierung des jeweiligen vereinzelte Drahtes 6 in dem Schacht 27 zu entnehmen. Aufgrund der vorherrschenden Erdanziehungskraft und der geneigten Ausrichtung der Trommel 27 können die vereinzelte Drähte 6 im Bereich der Antriebseinheit 23 aus dem Schacht 27 herausrutschen, sodass diese von der Antriebseinheit 23 aufgenommen und in Richtung des Ballenpressengehäuses 8 weiter transportiert sind. Der jeweilige Schacht 27 kann beispielsweise durch eine nicht dargestellte Klappe oder einen sonstigen Verschlussmechanismus geschlossen sein und erst wenn der gewünschte Schacht 27 im Bereich der Antriebseinheit 23 angeordnet ist, wird die Klappe oder die Verschlusseinrichtung geöffnet, um den Draht 6 aus dem Schacht 27 herausnehmen zu können.In figure 7 the rotational movement of the drum 26 and the positioning of the respective separated wire 6 in the shaft 27 can be seen. Due to the prevailing force of gravity and the inclined alignment of the drum 27, the individual wires 6 can slip out of the shaft 27 in the area of the drive unit 23, so that they are picked up by the drive unit 23 and transported further in the direction of the baler housing 8. The respective chute 27 can be closed, for example, by a flap (not shown) or some other locking mechanism, and only when the desired chute 27 is located in the area of the drive unit 23 is the flap or the locking device opened in order to remove the wire 6 from the chute 27 be able.

In Figur 8 ist schematisch die Verbindung zwischen den beiden freien Enden 12' und 12" des Drahtes 6 zur Bildung der Drahtschlinge 7 gezeigt. Dabei ist das erste freie Ende 12' mit einer Schlaufe versehen und an dem zweiten freien Ende 12" ist ein Widerhaken oder eine weitere Schlaufe vorhanden. Eine der beiden freien Enden 12' oder 12" ist dabei in die Schlaufe des anderen freien Endes 12"oder 12' einzustecken. Aufgrund der Rotationsbewegung des ersten freien Endes 12', die von der Zugeinheit 24 beim Straffen des Drahtes 6 ausgeübt ist, entsteht beim Lösen der beiden freien Enden 12' und 12" eine Rotationsbewegung, denn der Draht 6 steht unter einem bestimmten Vorspannung, wodurch sich die beiden freien Enden 12' und 12" des Drahtes 6 umeinander verdrillen. Dies bewirkt eine dauerhafte und zuverlässige Fixierung der beiden freien Enden 12' und 12" des Drahtes 6, sodass die Drahtschlinge 7 den im Pressraum 9 vorhandenen Ballen 3 in Pressrichtung 4 umreift.In figure 8 shows schematically the connection between the two free ends 12' and 12" of the wire 6 to form the wire loop 7. The first free end 12' is provided with a loop and the second free end 12" has a barb or another loop present. One of the two free ends 12' or 12'' is to be inserted into the loop of the other free end 12'' or 12'. Due to the rotational movement of the first free end 12', which is exerted by the pulling unit 24 when tightening the wire 6, a rotational movement occurs when the two free ends 12' and 12" are released, because the wire 6 is under a certain pretension, which the two free ends 12' and 12" of the wire 6 twisted around each other. This causes a permanent and reliable fixation of the two free ends 12' and 12'' of the wire 6, so that the wire loop 7 straps the bale 3 present in the baling chamber 9 in the pressing direction 4.

Die Verpackungseinrichtung 21 ist als modularer Bausatz ausführbar und kann folglich an bestehende Ballenpressen 1 nachträglich angebaut und dort verwendet sein.The packaging device 21 can be designed as a modular kit and can consequently be retrofitted to existing baling presses 1 and used there.
