Description

Die Erfindung bezieht sich auf eine Ballenpresse nach dem Oberbegriff des Patentanspruches 1.The invention relates to a baler according to the preamble of claim 1.

Solche Ballenpressen sind beispielsweise aus der DE 10 2009 053 134 A1 bekannt geworden. Das zu verpressende Gut, insbesondere Kartonagen, Altpapier, Folien oder PET- Flaschen, soll von derartigen Ballenpressen möglichst platzsparend verdichtet werden, um die derart verpressten Ballen kostengünstig transportieren und lagern zu können. Dabei ist es zwingend erforderlich, das verpresste Gut vor dessen Entnahme aus der Ballenpresse mittels einer oder mehrerer Drahtschlingen zu ummanteln, so dass das verpresste Gut nicht mehr auseinanderfallen kann.Such balers are for example from the DE 10 2009 053 134 A1 known. The material to be compressed, in particular cardboard packaging, waste paper, foils or PET bottles, should be compacted in a space-saving manner by such baling presses, so that the bales compressed in this way can be transported and stored inexpensively. It is imperative to encase the pressed material by means of one or more wire loops before it is removed from the baler, so that the pressed material can no longer fall apart.

Üblicherweise wird in die Einfüllöffnung der Ballenpresse solange das zu verpressende Gut eingefüllt, bis der Pressstempel eine vorgegebene Position erreicht hat, also die Größe des verpressten Gutes dem späteren Ballen im Wesentlichen entspricht. Sobald das verpresste Gut derart verdichtet in dem Pressraum der Ballenpresse mittels des Presstempels gehalten ist, ist eine Klappe an der Ballenpresse zu öffnen, um manuell die Drahtschlingen am Ende des verpressten Ballens, also zwischen diesem und dem Pressstempel, zu verknoten.The material to be compressed is usually filled into the filling opening of the baling press until the press ram has reached a predetermined position, that is to say the size of the compressed material essentially corresponds to the subsequent bale. As soon as the pressed material is held in the pressing chamber of the baling press by means of the press ram, a flap on the baling press is to be opened in order to manually knot the wire loops at the end of the pressed bale, i.e. between this and the press ram.

Solche Arbeiten sind einerseits äußerst zeitintensiv und andererseits fehlerbehaftet, da diese manuell von einem Bedienpersonal durchzuführen sind. Es ist nicht möglich, bei Ballenpressen, die einen vorgegebenen Ballenpressraum aufweisen, der beispielsweise einseitig von einer Tür, die gleich Begrenzung und damit als Anschlag für das verpresste Gut dient, verschlossen ist in den Pressraum einzugreifen. Durch die verschwenkbar an dem Ballenpressengehäuse angelenkte Tür kann nach dem Verpressen der verpackte Ballen aus dem Ballenpressraum entnommen werden.Such work is, on the one hand, extremely time-consuming and, on the other hand, prone to errors, since it has to be carried out manually by an operator. It is not possible for balers that have a predetermined baling space to use the For example, it is closed on one side by a door, which serves as a delimitation and thus as a stop for the pressed material, to reach into the pressing space. The door, which is pivotably hinged to the baling press housing, allows the packed bale to be removed from the baling room after pressing.

Beim Verpressen des eingefüllten Gutes in den Ballenpressraum durch den Pressstempel hängt nämlich die Position des Pressstempels im Wesentlichen davon ab, wieviel zu verpressendes Gut in den Ballenpressraum eingegeben wurde. Wird beim letzten Einfüllvorgang, vor Beendigung des Verpressungszyklus, nämlich zu viel oder weniger Gut eingefüllt, dann befindet sich der Pressstempel jeweils an unterschiedlichen Positionen, die in einem Bereich von etwa ± 5 cm auseinanderliegen können. Der für die Umschlingung des verpressten Ballens erforderliche Draht wird zwar automatisch beim Verpressen des Gutes von entsprechenden Abwicklungsrollen gezogen und verläuft dann seitlich in Längsrichtung der Ballenpresse, jedoch kann eine automatische oder maschinelle Verbindung der Drahtenden zwischen dem Pressstempel und dem Ballen nicht erfolgen, da der Pressstempel an unterschiedlichen nicht exakt definierten Positionen den Presszyklus beendet.When the filled goods are pressed into the baling space by the press ram, the position of the press ram depends essentially on how much material to be pressed has been entered into the baling space. If too much or less material is filled in during the last filling process, namely before the end of the compression cycle, the press ram is in each case at different positions which can be within a range of approximately ± 5 cm. The wire required to wrap the compressed bale is automatically drawn from the corresponding unwinding rollers when the goods are compressed and then runs laterally in the longitudinal direction of the baler, but an automatic or mechanical connection of the wire ends between the press ram and the bale cannot take place because the press ram The press cycle ends at different, not exactly defined positions.

Eine andere Art von Ballenpressen kann beispielsweise aus der DE 20 2012 004 276 U1 entnommen werden. Hierbei handelt es sich um eine Ballenpresse, die in Richtung des Hubwegs ausgerichtet, einen Auslasskanal aufweist, durch den der verpresste und verpackte Ballen durch das nachfolgend eingegebene zu verpressende Gut ausgeschoben wird und dabei gleichzeitig als Gegenanschlag für das zu verpressende Gut in dem Ballenpressraum dient. In dem Auslasskanal befinden sich mehrere verpresste und verpackte Ballen, die aufgrund der herrschenden Reibung zwischen diesen und der Innenwand des Auslasskanals eine ausreichende auf das zu verpressende Gut ausüben. Vorteilhafter Weise kann bei einem solchen Presssystem die Position des Pressstempels exakt vorgegeben werden, denn die in dem Auslasskanal angeordneten verpressten und verpackten Ballen sind relativ zu dem Ballenpressraum beweglich, so dass unabhängig von der eingefüllten Menge des Gutes die Position des Pressstempels ausgerichtet werden kann. Steigt nämlich die von dem Pressstempel auf das zu verpressende Gut ausgeübte Presskraft an, wird durch diese die bereits im Auslasskanal befindlichen Ballen mehr oder weniger verschoben.Another type of baler can for example be obtained from the DE 20 2012 004 276 U1 can be removed. This is a baling press that is aligned in the direction of the stroke and has an outlet channel through which the compressed and packaged bale is pushed out by the subsequently inputted material to be compressed and at the same time serves as a counter-stop for the material to be compressed in the baling room. In the outlet channel there are several compressed and packaged bales which, due to the friction between them and the inner wall of the outlet channel, exert sufficient pressure on the material to be compressed. Advantageously, the position of the press ram can be precisely specified in such a press system, because the pressed and packaged bales arranged in the outlet channel can be moved relative to the baling chamber, so that the position of the press ram can be aligned regardless of the amount of material filled. If the pressing force exerted by the press ram on the material to be pressed increases, the bales already located in the outlet channel are more or less displaced by this force.

Solche Ballenpressen können dann mittels einer maschinellen oder automatisierten Verbindungs- oder Verpackungseinrichtung versehen werden, die fest an dem Ballenpressengehäuse angeordnet ist und fluchtend bzw. in der selben Ebene wie der Pressstempel verlaufen. Die Endposition des Pressstempels nach der Beendigung des letzten Pressvorganges ist demnach exakt vorgegeben und die maschinell betriebene Verpackungseinrichtung kann die Drahtenden im Bereich des Pressstempels miteinander verbinden, so dass zum einen das verpresste Gut mit mindestens einer Drahtschlinge fest ummantelt ist und zum anderen für das nächste zu verpressende Gut bereits eine einseitig geschlossene Drahtschlinge im Bereich des Pressraums vorhanden ist, die durch das nachfolgend eingegebene Gut und die Hubbewegungen des Pressstempels in Richtung der Auslassöffnung bzw. des Auslasskanals verschoben wird, so dass sich der Pressvorgang und die Verpackung bzw. Umschnürung des fertig verpressten Ballens wiederholt.Such baling presses can then be provided by means of a mechanical or automated connecting or packaging device which is fixedly arranged on the baling press housing and runs in alignment or in the same plane as the press ram. The end position of the press ram after the end of the last pressing process is therefore precisely specified and the machine-operated packaging device can connect the wire ends in the area of the press ram so that on the one hand the pressed material is tightly encased with at least one wire loop and on the other hand it closes for the next For pressing material, a wire loop closed on one side is already present in the area of the pressing chamber, which is shifted by the subsequently entered material and the stroke movements of the pressing ram in the direction of the outlet opening or the outlet channel, so that the pressing process and the packaging or constriction of the finished pressed product are shifted Bale repeated.

Nachteiligerweise sind solche Ballenpressen jedoch äußerst groß bemessen, da der Auslasskanal oftmals eine Länge von drei und mehr Metern aufweist. Eine solche Länge des Auslasskanals ist für die zuverlässige Betriebsweise bzw. die Positionierung des Pressstempels exakt in der Ebene der Verpackungseinrichtung zwingend erforderlich.Disadvantageously, however, such baling presses are extremely large, since the outlet channel often has a length of three or more meters. Such a length of the outlet channel is absolutely necessary for the reliable mode of operation or the positioning of the ram exactly in the plane of the packaging device.

Des Weiteren ist beispielsweise aus DE 25 40 452 oder GB 2 439 935 A jeweils eine Ballenpresse gemäß dem Oberbegriff des Anspruchs 1 zu entnehmen, an der eine Verpackungseinrichtung angeordnet ist, die zum einen relativ zu dem Ballenpressengehäuse bewegbar ist und zum anderen den Draht aufnimmt, um diesen durch in den Pressstempel eingearbeitete Kanäle zu führen, sodass das verpresste Gut vollständig von dem Draht ummantelt ist. Die Verpackungseinrichtung und der Pressstempel verlaufen während des Umstellungsprozesses dabei fluchtend zueinander.Furthermore, for example, is off DE 25 40 452 or GB 2 439 935 A a baling press according to the preamble of claim 1, on which a packaging device is arranged, which on the one hand is movable relative to the baling press housing and on the other hand takes up the wire in order to guide it through channels worked into the press ram, so that the pressed material is completely covered by the wire. The packaging device and the ram run in alignment with one another during the changeover process.

Nachteiligerweise sind jedoch keinerlei technische Maßnahmen in diesem Stand der Technik beschrieben, durch die die jeweiligen Positionen des Pressstempels und der Verpackungseinrichtung überwacht, festgestellt und/oder zueinander ausgerichtet sind. Für einen ordnungsgemäßen Betriebsablauf ist es jedoch zwingend erforderlich, dass die Position des Pressstempels nach Beendigung des Pressvorganges erfasst und an eine geeignete Steuereinrichtung weitergeleitet ist, durch die anschließend die Verpackungseinrichtung zu dem Pressstempel bewegt ist, um die fluchtende Positionierung zu erreichen.Disadvantageously, however, no technical measures are described in this prior art, by means of which the respective positions of the press ram and the packaging device are monitored, determined and / or aligned with one another. However, for a proper operating sequence it is imperative that the position of the press ram is correct after the press process has ended is detected and forwarded to a suitable control device, by which the packaging device is then moved to the ram in order to achieve the aligned positioning.

Es ist daher Aufgabe der Erfindung, eine Ballenpresse der eingangs genannten Gattung zur Verfügung zu stellen, die eine maschinell betriebene Verpackung des fertig verpressten Gutes in dem Ballenpressraum ermöglicht und zwar derart, dass die Länge des Ballens die Position des Presstempels und des Verpackungsmaterials vorgibt.It is therefore the object of the invention to provide a baling press of the type mentioned at the outset which enables machine-operated packaging of the finished compressed goods in the baling space in such a way that the length of the bale dictates the position of the press ram and the packaging material.

Diese Aufgaben sind erfindungsgemäß durch die Merkmale des kennzeichnenden Teils von Patentanspruch 1 gelöst.According to the invention, these objects are achieved 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 emerge from the subclaims.

Dadurch, dass an dem Pressstempel und an der Verpackungseinrichtung jeweils ein Sensor angeordnet ist, durch die die Positionen des Presstempels und der Verpackungseinrichtung steuerbar sind, dass die Hubwege des Presstempels durch die Sensoren gemessen sind, dass durch die gemessenen Bewegungen des Pressstempels die Beendigung des jeweiligen Pressvorgangs feststellbar ist, und dass an der Verpackungseinrichtung der Sensor vorgesehen ist, durch den die Position der Verpackungseinrichtung zu der Position des Pressstempels ausgerichtet ist, ist gewährleistet, dass unabhängig von der Position des Pressstempels der von den Drahtrollen abgewickelte Draht in das Innere des Ballenpressengehäuses mittels der Verpackungseinrichtung sowie in den Pressstempel hineingeführt ist, um die Drahtschlinge um den Ballen zu bilden. Somit ist erreicht, dass die Befestigung der Drahtschlinge automatisch durch die Hubbewegung der Verpackungseinrichtung erfolgt und dass unabhängig von der Position des Pressstempels nach Beendigung des Pressvorganges die Bildung der Drahtschlinge mit Hilfe der Verpackungseinrichtung möglich ist.The fact that a sensor is arranged on the press ram and on the packaging device, by means of which the positions of the press ram and the packaging device can be controlled, that the stroke paths of the press ram are measured by the sensors, that the measured movements of the press ram result in the termination of the respective Pressing process can be determined, and that the sensor is provided on the packaging device, by means of which the position of the packaging device is aligned with the position of the press ram, it is ensured that regardless of the position of the press ram, the wire unwound from the wire rolls into the interior of the baler housing by means of the packaging device as well as into the ram to form the wire loop around the bale. Thus it is achieved that the The wire loop is fastened automatically by the lifting movement of the packaging device and that, regardless of the position of the press ram, the wire loop can be formed with the aid of the packaging device after the pressing process has ended.

Sowohl die Hubbewegungen des Pressstempels als auch die endgültige Position des Pressstempels nach Beendigung des Pressvorganges kann mit Hilfe von Sensoren erfasst sein, so dass anschließend die relativ an dem Ballenpressengehäuse angelenkte Verpackungseinrichtung exakt fluchtend zu der Position des Pressstempels verfahren und ausgerichtet werden kann, um den jeweiligen Draht von der Drahtrolle in das Innere des Pressstempels einzutauchen.Both the stroke movements of the press ram and the final position of the press ram after completion of the pressing process can be recorded with the help of sensors, so that the packaging device, which is linked relative to the baling press housing, can then be moved and aligned exactly in line with the position of the press ram, around the respective Dip the wire from the wire roll into the inside of the press ram.

Darüber hinaus ist eine lang bemessene Ausfuhröffnung in Form eines Kanals nicht mehr notwendig, so dass die Baugröße der Ballenpresse erheblich reduziert ist. Der verpresste Ballen kann nämlich durch die an dem Ballenpressengehäuse verschwenkbar angelegte Tür entnommen werden.In addition, a long discharge opening in the form of a channel is no longer necessary, so that the size of the baler is considerably reduced. The compacted bale can namely be removed through the door which is pivotably mounted on the baler housing.

Eine in Figur 1 abgebildete Ballenpresse 1 dient dazu, aus vereinzelten Gütern 2 einen verpressten Ballen 3 herzustellen, der mittels einer Drahtschlinge 7 umreift ist, so dass die erzeugte Form des Ballens 3 während des weiteren Transport- und Lagervorganges nicht verändert ist. Durch die Ballenpresse 1 können beispielsweise Abfallprodukte aus Kartonage, aus Folien oder PET- Flaschen zu dem Ballen 3 geformt werden.One in Figure 1 The baler 1 shown is used to produce a compressed bale 3 from isolated goods 2, which is strapped by means of a wire loop 7 so that the shape of the bale 3 produced is not changed during the further transport and storage process. The baling press 1 can, for example, form waste products from cardboard, from foils or PET bottles into the bale 3.

Die Ballenpresse 1 weist eine Längsachse 4 auf, die horizontal, vertikal oder geneigt ausgerichtet sein kann; je nach Einsatz und Verwendungszweck der Ballenpresse 1.The baler 1 has a longitudinal axis 4 which can be oriented horizontally, vertically or inclined; depending on the use and purpose of the baler 1.

Die Ballenpresse 1 besteht aus einem rechteckförmigen Ballenpressengehäuse 8, das einen Innenraum ummantelt. In dem Ballenpressengehäuse 8 ist ein Pressstempel 9 vorgesehen, der durch eine Hubeinrichtung oder einen sonstigen pneumatischen, elektrischen, mechanischen Antrieb in einer axialen Bewegung, parallel zu der Längsachse 4 hin und her bewegbar ist. Des Weiteren ist in das Ballenpressengehäuse 8 eine Einfüllöffnung 13 eingearbeitet, durch die das zu verpressende Gut 2 in das Ballenpressengehäuse 8 einfüllbar ist. In dem Ausgangszustand bzw. vor jedem Pressvorgang ist der Pressstempel 9 seitlich neben der Einfüllöffnung 13 in der Ausgangsstellung positioniert, so dass das zu verpressende Gut in das Ballenpressengehäuse 8 eingefüllt werden kann, ohne dass der Pressstempel 9 diesen Einfüllvorgang behindert.The baling press 1 consists of a rectangular baling press housing 8 which encloses an interior space. A press ram 9 is provided in the baling press housing 8, which can be moved back and forth in an axial movement parallel to the longitudinal axis 4 by a lifting device or some other pneumatic, electrical, mechanical drive. Furthermore, a filling opening 13 is incorporated into the baling press housing 8, through which the material 2 to be compressed can be filled into the baling press housing 8. In the initial state or before each pressing process, the ram 9 is positioned laterally next to the filling opening 13 in the initial position, so that the material to be pressed can be filled into the baling press housing 8 without the ram 9 hindering this filling process.

Der Pressstempel 9 wird anschließend betätigt und dabei in Richtung eines Druckraumes 10 bewegt. Der Druckraum 10 wird zum einen an vier Seiten durch die Wände des Ballenpressengehäuses 8 und durch den Pressstempel 9 sowie eine an dem Ballenpressengehäuse 8 mittels Scharnieren 12 angelegten Tür 11 verschlossen. Die Tür 11 ist demnach den Pressstempel 9 gegenüberliegend angeordnet und kann von außen geöffnet werden, um den verpressten Ballen 3 aus dem Ballenpressengehäuse 8 zu entnehmen. Folglich dient die Tür 11 zum einen als Anschlag oder Gegenlager für den Pressstempel 9 und zum anderen bietet diese den Zugang in das Innere des Ballenpressengehäuses 8, um den Ballen 3 aus diesem zu entfernen.The ram 9 is then actuated and moved in the direction of a pressure chamber 10. The pressure chamber 10 is on the one hand on four sides by the walls of the baler housing 8 and by the ram 9 and one on the The baler housing 8 is closed by means of the door 11 placed on the hinges 12. The door 11 is accordingly arranged opposite the press ram 9 and can be opened from the outside in order to remove the pressed bale 3 from the baler housing 8. Consequently, the door 11 serves on the one hand as a stop or counter-bearing for the press ram 9 and on the other hand it provides access to the interior of the baling press housing 8 in order to remove the bale 3 therefrom.

Auf der Außenseite des Ballenpressengehäuses 8 sind zwei Drahtrollen 5 vorgesehen, auf denen jeweils ein Draht 6 jeweils aufgerollt ist und, wie nachfolgend beschrieben, von den Drahtrollen 5 abgewickelt wird, während der Pressstempel 9 das eingefüllte Gut 2 in den Druckraum 10 fördert. Die vereinzelten Drähte 6 werden zunächst in das Innere des Ballenpressengehäuses 8 geführt und sind miteinander zu verbinden, um den Ausgangszustand der Drahtschlinge 7 herzustellen. Sobald das Gut 2 durch die Einfüllöffnung 13 in das Innere des Ballenpressengehäuses 8 eingefüllt ist und der Pressstempel 9 dieses Gut 2 in den Druckraum 10 gefördert hat, wird demnach die Drahtschlinge 7 und somit der jeweilige Draht 6 von der Drahtrolle 5 abgewickelt und der Draht 6 bzw. die noch einseitig offene Drahtschlinge 7 liegt zwischen einer der Innenwände des Ballenpressengehäuses 8 und dem bereits verpressten Teilbereich des Ballens 3 an.On the outside of the baler housing 8, two wire reels 5 are provided, on each of which a wire 6 is rolled up and, as described below, is unwound from the wire reels 5, while the ram 9 conveys the filled material 2 into the pressure chamber 10. The separated wires 6 are first fed into the interior of the baler housing 8 and are to be connected to one another in order to produce the initial state of the wire loop 7. As soon as the product 2 is filled into the interior of the baling press housing 8 through the filling opening 13 and the ram 9 has conveyed this product 2 into the pressure chamber 10, the wire loop 7 and thus the respective wire 6 is unwound from the wire reel 5 and the wire 6 or the wire loop 7, which is still open on one side, lies between one of the inner walls of the baling press housing 8 and the already compressed part of the bale 3.

Mit der Bezugsziffer 15 ist der Bereich 15 gekennzeichnet in dem die Verpackungseinrichtung 21 angeordnet sein kann und in dem der Pressstempel 9 verlaufen kann sobald genügend Gut 2 in den Druckraum 10 eingefüllt wurde. Dabei wird mittels Sensoren und sonstiger elektrischer oder mechanischer Hilfsmittel der Hubweg des Pressstempels 9 bzw. die Position gemessen, so dass aus diesen Messwerten Rückschlüsse hergeleitet werden können, welche Menge des verpressten Gutes 2 sich bereits im Druckraum 10 befindet, um die Größe des fertig verpressten Ballens 3 möglichst einheitlich zu gestalten. Ist der Pressstempel 9 demnach in dem Bereich 15 in seiner Endposition, die in einer Größenordnung von ±10 cm variieren kann, wird eine Verpackungseinrichtung 21 zu der Position des Pressstempels 9 zugestellt.The area 15 in which the packaging device 21 can be arranged and in which the press ram 9 can run as soon as enough material 2 has been filled into the pressure chamber 10 is identified by the reference number 15. The stroke of the ram 9 or the position is measured by means of sensors and other electrical or mechanical aids, so that conclusions can be drawn from these measured values as to which amount of the pressed material 2 is already in the pressure chamber 10, by the size of the finished pressed one Ballens 3 to be designed as uniformly as possible. If the press ram 9 is accordingly in its end position in the area 15, which can vary in an order of magnitude of ± 10 cm, a packaging device 21 is advanced to the position of the press ram 9.

Die Verpackungseinrichtung 21 ist durch eine Schiene 22 oder Linearführung, die fest mit dem Ballenpressengehäuse 8 verbunden ist, parallen und beabstandet zu der Längsachse 4 der Ballenpresse 1 verschiebbar gelagert. Insbesondere den Figu- ren 2a und 2b ist zu entnehmen, dass die Verpackungseinrichtung 21 mit Hilfe eines Antriebes 24 in trieblicher Wirkverbindung über eine Spindel 23 steht. Sobald demnach der Antrieb 24 verfährt, rotiert die Spindel 23 um die eigene Achse, so dass die Verpackungseinrichtung 21 nach Art eines Linearantriebes relativ zu dem Ballenpressengehäuse 8 parallel zu der Längsachse in Richtung der Position des Presstempels 9 bewegt ist. Die Rotationsrichtung der Spindel 23 bzw. des Antriebes 24 kann dabei im oder entgegengesetzt zu dem Uhrzeigersinn eingestellt werden.The packaging device 21 is mounted parallel to and at a distance from the longitudinal axis 4 of the baling press 1 so as to be displaceable by a rail 22 or linear guide which is firmly connected to the baling press housing 8. In particular the Figurative ren 2a and 2b it can be seen that the packaging device 21 is operatively connected via a spindle 23 with the aid of a drive 24. As soon as the drive 24 moves, the spindle 23 rotates around its own axis, so that the packaging device 21 is moved in the manner of a linear drive relative to the baler housing 8 parallel to the longitudinal axis in the direction of the position of the press ram 9. The direction of rotation of the spindle 23 or of the drive 24 can be adjusted clockwise or counterclockwise.

Um die Erzeugung der Drahtschlinge 7 mit Hilfe der Verpackungseinrichtung 21 zu erreichen, ist es erforderlich, dass zum einen die Position des Pressstempels 9 beibehalten ist, um das verpresste Gut 2 zu dem Ballen 3 zu fixieren und zum anderen den jeweiligen Draht 6 von der Drahtrolle 5 in das Innere des Pressstempels 9 mit Hilfe der Verpackungseinrichtung 21 einzutauchen. Durch die Verpackungseinrichtung 21 wird nämlich eine Schlaufe des Drahtes 6 gebildet, die im Inneren des Pressstempels 9 gemäß Figur 2a verläuft.In order to generate the wire loop 7 with the help of the packaging device 21, it is necessary, on the one hand, to maintain the position of the press ram 9 in order to fix the pressed material 2 to the bale 3 and, on the other hand, to fix the respective wire 6 from the wire roll 5 to dip into the interior of the ram 9 with the aid of the packaging device 21. A loop of the wire 6 is namely formed by the packaging device 21, which is inside the press ram 9 according to FIG Figure 2a runs.

Folglich ist es zwingend erforderlich, dass der Pressstempel 9 fluchtend zu der Verpackungseinrichtung 21 steht. Zu diesem Zweck ist sowohl an dem Pressstempel 9 ein Sensor 26 als auch an der Verpackungseinrichtung 21 ein Sensor 27 vorgesehen, die beispielsweise mittels Lichtstrahlen, Magnetfeldern, elektrisch oder auf sonstige physikalische Weise die Position des Pressstempel 9 und der Verpackungseinrichtung 21 erfassen und miteinander kommunizieren. Demnach kann die Verpackungseinrichtung 21 entlang der Längsachse 4 in Richtung des Pressstempels 9 solange bewegt werden, bis diese fluchtend zu dem Presstempel 9 verfahren ist. Die Verpackungseinrichtung 21 weist einen Kolben 29 auf der senkrecht zu der Längsachse 4 ausgerichtet ist und der in den Pressstempel 9 eintauchen kann. Hierzu weist der Pressstempel 9 einen Zwischenraum 16 auf, der senkrecht zu der Längsachse 4 in diesen eingebracht ist und sich nutartig entlang einer Achse über den gesamten Presstempel erstreckt..Consequently, it is imperative that the ram 9 is in alignment with the packaging device 21. For this purpose, a sensor 26 is provided on the ram 9 as well as a sensor 27 on the packaging device 21, which detect the position of the ram 9 and the packaging device 21, for example by means of light beams, magnetic fields, electrically or in some other physical manner, and communicate with one another. Accordingly, the packaging device 21 can be moved along the longitudinal axis 4 in the direction of the press ram 9 until it has moved in alignment with the press ram 9. The packaging device 21 has a piston 29 on which is aligned perpendicular to the longitudinal axis 4 and which can dip into the ram 9. For this purpose, the press ram 9 has an interspace 16, which is introduced into the longitudinal axis 4 at right angles to it and extends in the manner of a groove along an axis over the entire press ram.

Der Kolben 29 der Verpackungseinrichtung 21 kann hubweise in das Innere des Pressstempels 9 durch den Zwischenraum 16 eingeführt werden. Der Kolben 29 nimmt dabei den einen Draht 6 mit und wickelt diesen von der entsprechenden Drahtrolle 5 ab, so dass der Draht 6 eine Umreifung bildet, die in dem Zwischenraum 16 des Pressstempels 9 verläuft. Der Kolben 29 der Verpackungseinrichtung 21 kann hydraulisch oder pneumatisch mittels eines elektrisch oder mechanisch Antriebes bewegt werden. Der Antrieb 24 kann auch dazu verwendet werden, die Hubbewegung des Kolbens 29 der Verpackungseinrichtung 21 zu erzeugen.The piston 29 of the packaging device 21 can be introduced into the interior of the press ram 9 through the space 16 in a stroke-wise manner. The piston 29 takes one wire 6 with it and unwinds it from the corresponding wire roll 5, so that the wire 6 forms a strapping in the space 16 of the ram 9 runs. The piston 29 of the packaging device 21 can be moved hydraulically or pneumatically by means of an electrical or mechanical drive. The drive 24 can also be used to generate the stroke movement of the piston 29 of the packaging device 21.

Sobald der Kolben 29 der Verpackungseinrichtung 21 auf der gegenüberliegenden Seite des Ballenpressengehäuses 8 angekommen ist, wird die Umreifung des Ballens 3 dadurch gebildet, dass die Schlaufe des Drahtes 6 getrennt und der gegenüberliegende Draht 6 in den Zwischenraum 16 des Pressstempels 9 gezogen und durchtrennt ist. Das lose Ende des Drahtes 6, das um den Ballen 3 gewickelt ist, ist mit dem einen Ende der Schlaufe des oberen Drahtes 6 durch die Verpackungseinrichtung 21 verbunden, so dass die Drahtschlinge 7, die den Ballen 3 umreift, gebildet ist, und die weiteren beiden losen Enden der gegenüberliegenden Drähte 6 durch die Verpackungseinrichtung 21 miteinander verbunden sind, um erneut einen Teil einer neuen Drahtschlinge 7 zu erzeugen.As soon as the piston 29 of the packaging device 21 has arrived on the opposite side of the baling press housing 8, the strapping of the bale 3 is formed in that the loop of the wire 6 is separated and the opposite wire 6 is pulled into the space 16 of the press ram 9 and cut. The loose end of the wire 6, which is wrapped around the bale 3, is connected to one end of the loop of the upper wire 6 through the packaging device 21 so that the wire loop 7 which straps around the bale 3 is formed, and the others both loose ends of the opposing wires 6 are connected to one another by the packaging device 21 in order to produce a part of a new wire loop 7 again.

Sobald dieser Verbindungsvorgang zwischen den losen Enden der Drähte 6 beendet ist, wird der Kolben 29 der Verpackungseinrichtung 21 aus dem Pressstempel 9 gezogen und der Pressstempel 9 in Richtung der Ausgangsposition zurückgefahren. Um die Bewegung des Pressstempels 9 freizugeben, da in diesem die losen Enden der neuen Drahtschlinge 7 vorhanden sind, ist in diesem ein Ausführschlitz 30 eingearbeitet, durch den die neue Drahtschlinge 7 hindurchtritt, wenn der Pressstempel 9 zurückgezogen ist. Der Ausführschlitz 30 ist mit dem Zwischenraum 16 verbunden und bilden zusammen eine Art T-Nut. Vorteilhafter Weise sollte der Ausführschlitz V-förmig ausgestaltet sein, um ein hindurchtreten der neuen Drahtschlinge zu begünstigen.As soon as this connection process between the loose ends of the wires 6 has ended, the piston 29 of the packaging device 21 is pulled out of the press ram 9 and the press ram 9 is moved back in the direction of the starting position. In order to release the movement of the press ram 9, since the loose ends of the new wire loop 7 are present in it, an outlet slot 30 is machined into it, through which the new wire loop 7 passes when the press ram 9 is withdrawn. The discharge slot 30 is connected to the space 16 and together form a type of T-groove. Advantageously, the outfeed slot should be V-shaped in order to encourage the new wire loop to pass through.

Für den weiteren Einfüllvorgang befindet sich demnach der Pressstempel 9 links von der Einfüllöffnung 13 und die neue Drahtschlinge 7 rechts von der Öffnung 13 gemäß den Figuren 1 bis 2b. Der Pressvorgang und die Verpackung des verpressten Ballens 3 wiederholen sich demnach, ohne dass manuell die Drahtschlinge 7 zu erzeugen ist.For the further filling process, the ram 9 is accordingly to the left of the filling opening 13 and the new wire loop 7 is to the right of the opening 13 according to FIG Figures 1 to 2b . The pressing process and the packaging of the pressed bale 3 are accordingly repeated without the wire loop 7 having to be produced manually.

Unabhängig von der Position des Pressstempels 9 kann automatisiert die Drahtschlinge 7 um den Ballen 3 gelegt werden. Darüber hinaus kann sich der Pressstempel 9 in einer beliebigen Position im Bereich 15 befinden, die im Wesentlichen den Verstellweg der Verpackungseinrichtung 21 entspricht, so dass die in das Ballenpressengehäuse 8 eingefüllte Menge des Gutes 2 variabel gestaltet ist. Dies ist insbesondere während des letzten Pressvorganges vorteilhaft, denn der Benutzer der Ballenpresse 1 kann Gut 2 einfüllen ohne dass dadurch der Pressvorgang des Pressstempels 9 gestört ist.Regardless of the position of the ram 9, the wire loop 7 can be placed around the bale 3 in an automated manner. In addition, the ram 9 can be in any position in the area 15, which essentially corresponds to the adjustment path of the packaging device 21, so that the amount of the goods 2 filled into the baler housing 8 is variable. This is particularly advantageous during the last pressing process, because the user of the baling press 1 can fill in product 2 without the pressing process of the press ram 9 being disturbed as a result.

Die in den Figuren 2a und 2b abgebildete Ausführungsvariante der Spindel 23 kann ohne weiteres durch einen Ketten- oder Keilriemenantrieb bzw. durch ein elektrisch, hydraulisch oder pneumatisch betätigbaren Druckkolben ersetzt werden.The ones in the Figures 2a and 2 B The illustrated variant of the spindle 23 can easily be replaced by a chain or V-belt drive or by an electrically, hydraulically or pneumatically actuated pressure piston.

Der Ballen 3 kann durch eine Vielzahl von Drahtschlingen 7 umreift werden. Hierzu können mehrere Drähte 6 durch ein oder mehrere Kolben 29 um den Ballen gelegt werden. Der Kolben 29 kann auch als Teleskoparm oder Gestänge ausgebildet sein, um eine möglichst kleine Bauform zu erzielen.The bale 3 can be strapped by a plurality of wire loops 7. For this purpose, several wires 6 can be placed around the bale through one or more pistons 29. The piston 29 can also be designed as a telescopic arm or linkage in order to achieve the smallest possible structural shape.
