Definitions
- the invention relates to a packaging device and a packaging method having the features in the preamble of the method and device main claim.
- the packaging consists of a bottom foil and a cover foil, which are beaten and applied around the bale. In addition, a belly bandage can be attached.
- This film packaging is usually under the strapping. The packaging and the strapping are applied at a time when the pressed bales are still clamped by the under a very high pressure of eg several hundred tons between press dies. Such pressed bales have a very high compression and tend after expansion to expand.
- the packaging and the fixation must be stable accordingly.
- the invention solves this problem with the features in the method and device main claim.
- the claimed packaging technique with the overdrawing device and the Dehnhaube has the advantage that the packaging of the bale can be done after its fixation, for example by attaching a strapping.
- the shrink wrap with the Dehnhaube can thus take place either inside or outside a baler.
- several balers may have one or more common packaging devices.
- the bales can be highly compressed and e.g. be compressed with pressing forces of several hundred tons.
- the prepared stretch hood is placed over the fixed bale and, due to the elastic properties of the hood material, it contracts close to the bale surface when shrinking.
- the expansion hood is clamped and, if necessary, reefed. It can then be placed over the bale with its bottom in front, being folded over and turned inside out and rolling on the bale. This is a particularly favorable investment technique.
- a possibly outer bottom seam can be brought by turning in a protected inner layer on the bale.
- the expansion hood can be shorter than the covered bale length, with the bale protruding through the opening of the expansion hood.
- the Dehnhaube can be outside on a fixation or strapping, which brings advantages in the subsequent opening of the packaging and the strapping with it and can prevent the high-pressure strapping bands.
- the pressed bales can be enclosed by means of one or more expansion hoods by a tightly sealed envelope.
- the overlapping arrangement of the expansion hoods and possibly a different partial enclosure results in a dense packing or packaging of the pressing bale against environmental influences.
- An additional fixation of the one or more Dehnhauben with each other or on the bale can be dispensed with.
- the packaging technology has various economic advantages. On the one hand, the construction costs of the packaging device can be reduced compared to conventional constructions, whereby a maximum utilization of a packaging device provided for a plurality of balers can be achieved. In addition, cost-effective materials, in particular elastic polyethylene stretch films, which are cheaper than other packaging films, can be used for the stretch hoods.
- baling press a suitable device
- any material entrainment can be removed with a suitable cleaning technique, eg by brushing, suction or the like.
- a suitable cleaning technique eg by brushing, suction or the like.
- variety-specific ball carriers can be used.
- a particularly favorable possibility is the arrangement of a pre-packaging device in the baling area.
- a bottom foil can be applied, beaten laterally around a partial area of the press bale and then fixed with a strapping.
- the bottom foil prevents a bale material removal and thus a Materialverschleppung.
- the sub-cladding can already form a first essential part of the overall packaging, so that it can be sufficient to then attach only a Dehnhaube on the press bale, which overlaps the existing sub-cladding.
- the packaging device may have a turning device in order to attach Dehnhauben from different sides on the pressed bales and slipping over.
- the packaging of a press bale with two expansion hoods which are applied eg on opposite sides of the bale and outside the fixation, has particular advantages.
- the overlapping point of the Dehnhauben is particularly dense and protects the bale against external influences such as moisture, moisture, dust, etc. It can also fall out fibers or other small parts of the bale, which in particular prevents mixing of bale materials and purity of variety even during transport and the Storage of the packed bale guaranteed.
- the stretch hoods can very easily be removed separately and before fixing, without material residues of the packaging remaining on the pressed bale. As a result, contamination of the pressed bale material is excluded by the packaging material.
- the overdrawing device may first stretch an expansion hood to an excess and then slip it over at least three sides by overrunning the press bale and rolling over the press bale. When slipping over, the elastically shrinking stretch hood material lays tight against the bale surface.
- the Dehnhaube can be made within the packaging device of a film tube in a particularly cost-effective manner.
- the hood dimensions can be varied to adapt to different bale formats.
- the packaging technique according to the invention can be used in new balers or baling plants. It can also be retrofitted to existing balers and baling systems and replaced with existing packaging equipment.
- the bale logistics can be converted to come from a press-tied bale wrapper to a central bale wrapper.

Abstract
Description
Die Erfindung betrifft eine Verpackungseinrichtung und ein Verpackungsverfahren mit den Merkmalen im Oberbegriff des Verfahrens- und Vorrichtungshauptanspruchs.The invention relates to a packaging device and a packaging method having the features in the preamble of the method and device main claim.

Es ist Aufgabe der vorliegenden Erfindung, eine bessere Verpackungstechnik aufzuzeigen.It is an object of the present invention to show a better packaging technique.
Die Erfindung löst diese Aufgabe mit den Merkmalen im Verfahrens- und Vorrichtungshauptanspruch.The invention solves this problem with the features in the method and device main claim.
Die beanspruchte Verpackungstechnik mit der Überzieheinrichtung und der Dehnhaube hat den Vorteil, dass die Verpackung des Ballens nach seiner Fixierung, beispielsweise durch Anbringen einer Umreifung, erfolgen kann. Die Schrumpfverpackung mit der Dehnhaube kann damit wahlweise innerhalb oder außerhalb einer Ballenpresse stattfinden. Außerdem können mehrere Ballenpressen eine oder mehrere gemeinsame Verpackungseinrichtungen haben. Die Ballen können hochverdichtet und z.B. mit Presskräften von mehreren hundert Tonnen komprimiert sein.The claimed packaging technique with the overdrawing device and the Dehnhaube has the advantage that the packaging of the bale can be done after its fixation, for example by attaching a strapping. The shrink wrap with the Dehnhaube can thus take place either inside or outside a baler. In addition, several balers may have one or more common packaging devices. The bales can be highly compressed and e.g. be compressed with pressing forces of several hundred tons.
Die vorbereitete Dehnhaube wird über den fixierten Ballen gelegt und legt sich durch die dehnelastischen Eigenschaften des Haubenmaterials beim Schrumpfen dicht an die Ballenoberfläche an. Die Dehnhaube wird aufgespannt und ggf. gerefft. Sie kann anschließend mit ihrem Boden voraus über den Ballen gestülpt werden, wobei sie umgeklappt und von innen nach außen gewendet wird und sich auf dem Ballen abrollt. Dies ist eine besonders günstige Anlegetechnik. Eine evtl. äußere Bodennaht kann durch das Wenden in eine geschützte Innenlage am Ballen gebracht werden. Die Dehnhaube kann kürzer als die bedeckte Ballenlänge sein, wobei der Ballen durch die Öffnung der Dehnhaube ragt.The prepared stretch hood is placed over the fixed bale and, due to the elastic properties of the hood material, it contracts close to the bale surface when shrinking. The expansion hood is clamped and, if necessary, reefed. It can then be placed over the bale with its bottom in front, being folded over and turned inside out and rolling on the bale. This is a particularly favorable investment technique. A possibly outer bottom seam can be brought by turning in a protected inner layer on the bale. The expansion hood can be shorter than the covered bale length, with the bale protruding through the opening of the expansion hood.
Die Dehnhaube kann außen auf einer Fixierung oder Umreifung liegen, was Vorteile beim späteren Öffnen der Verpackung und der Umreifung mit sich bringt und ein Aufschlagen der unter hohem Druck stehenden Umreifungsbänder verhindern kann.The Dehnhaube can be outside on a fixation or strapping, which brings advantages in the subsequent opening of the packaging and the strapping with it and can prevent the high-pressure strapping bands.
Der Pressballen kann mittels einer oder mehrerer Dehnhauben von einer allseitig dichten Umhüllung umschlossen sein. Durch die überlappende Anlage der Dehnhauben und einer evtl. anderen Teilumhüllung ergibt sich eine gegen Umgebungseinflüsse dichte Emballage oder Verpackung des Pressballens. Eine zusätzliche Fixierung der einen oder mehreren Dehnhauben untereinander oder auf dem Ballen kann entbehrlich sein.The pressed bales can be enclosed by means of one or more expansion hoods by a tightly sealed envelope. The overlapping arrangement of the expansion hoods and possibly a different partial enclosure results in a dense packing or packaging of the pressing bale against environmental influences. An additional fixation of the one or more Dehnhauben with each other or on the bale can be dispensed with.
Die Verpackungstechnik hat verschiedene wirtschaftliche Vorteile. Einerseits kann der Bauaufwand der Verpackungseinrichtung gegenüber herkömmlichen Konstruktionen reduziert werden, wobei auch eine maximale Auslastung einer für mehrere Ballenpressen vorgesehenen Verpackungseinrichtung erreicht werden kann. Außerdem können für die Dehnhauben kostengünstige Materialien, insbesondere dehnelastische Stretch-Folien aus Polyethylen verwendet werden, die billiger als andere Verpackungsfolien sind.The packaging technology has various economic advantages. On the one hand, the construction costs of the packaging device can be reduced compared to conventional constructions, whereby a maximum utilization of a packaging device provided for a plurality of balers can be achieved. In addition, cost-effective materials, in particular elastic polyethylene stretch films, which are cheaper than other packaging films, can be used for the stretch hoods.
Wenn in einer Ballenpresse oder einer Ballenpressanlage unterschiedliche Ballenmaterialien verarbeitet werden, können Probleme mit einer Materialverschleppung und einer damit verbundenen Verunreinigung unter Materialvermischung der Pressballen entstehen. Die Erfindung sieht vor, mit einer geeigneten Einrichtung diesen Phänomenen im Zuführbereich zwischen der Ballenpresse und der Verpackungseinrichtung zu begegnen. Dies ist auf verschiedene Weise möglich. Mit einer Reinigungsvorrichtung im Zuführbereich und insbesondere im Bereich der Förderer, können etwaige Materialverschleppungen mit einer geeigneten Reinigungstechnik, z.B. durch Bürsten, Absaugen oder dgl. entfernt werden. Alternativ können sortenspezifische Ballenträger eingesetzt werden. Eine besonders günstige Möglichkeit ist die Anordnung einer Vorverpackungseinrichtung im Bereich der Ballenpresse.If different balers are processed in a baler or baler, problems with material carryover and associated contamination can result in material mixing of the pressed bales. The invention provides, with a suitable device, to counteract these phenomena in the feed area between the baling press and the packaging device. This is possible in different ways. With a cleaning device in the feed area and in particular in the area of the conveyor, any material entrainment can be removed with a suitable cleaning technique, eg by brushing, suction or the like. Alternatively, variety-specific ball carriers can be used. A particularly favorable possibility is the arrangement of a pre-packaging device in the baling area.
Diese kann vor oder während der Fixierung des Pressballens eine Teilumhüllung anbringen. Hierbei kann insbesondere bei der Herstellung des Pressballens eine Bodenfolie angebracht, seitlich um einen Teilbereich des Pressballens geschlagen und anschließend mit einer Umreifung fixiert werden. Die Bodenfolie verhindert einen Ballenmaterialabtrag und damit eine Materialverschleppung. Außerdem kann die Teilumhüllung bereits einen ersten wesentlichen Bestandteil der Gesamtverpackung bilden, sodass es genügen kann, auf dem Pressballen anschließend nur eine Dehnhaube anzubringen, welche die vorhandene Teilumhüllung überlappt.This can attach before or during the fixation of the press bale a Teilumhüllung. In this case, in particular during the production of the press bale, a bottom foil can be applied, beaten laterally around a partial area of the press bale and then fixed with a strapping. The bottom foil prevents a bale material removal and thus a Materialverschleppung. In addition, the sub-cladding can already form a first essential part of the overall packaging, so that it can be sufficient to then attach only a Dehnhaube on the press bale, which overlaps the existing sub-cladding.
Wenn ein Pressballen nur in Dehnhauben verpackt werden soll, kann die Verpackungseinrichtung eine Wendeeinrichtung aufweisen, um Dehnhauben von verschiedenen Seiten her auf dem Pressballen anbringen und überstülpen zu können.If a press bale is to be packaged only in stretch hoods, the packaging device may have a turning device in order to attach Dehnhauben from different sides on the pressed bales and slipping over.
Die Verpackung eines Pressballens mit zwei Dehnhauben, die z.B. auf gegenüberliegenden Seiten des Ballens und außerhalb der Fixierung aufgebracht werden, hat besondere Vorzüge. Die Überlappungsstelle der Dehnhauben ist besonders dicht und schützt den Ballen sicher vor externen Einflüssen wie Feuchtigkeit, Nässe, Staub etc. Es können auch keine Fasern oder sonstige Kleinteile des Ballens herausfallen, was insbesondere eine Vermischung von Ballenmaterialien verhindert und Sortenreinheit auch während des Transports und der Lagerung des verpackten Ballens garantiert. Beim Entpacken des Ballens lassen sich die Dehnhauben sehr leicht separat und vor der Fixierung entfernen, ohne dass Materialreste der Verpackung am Pressballen verbleiben. Hierdurch ist auch eine Verunreinigung des Pressballen-Materials durch das Verpackungsmaterial ausgeschlossen.The packaging of a press bale with two expansion hoods, which are applied eg on opposite sides of the bale and outside the fixation, has particular advantages. The overlapping point of the Dehnhauben is particularly dense and protects the bale against external influences such as moisture, moisture, dust, etc. It can also fall out fibers or other small parts of the bale, which in particular prevents mixing of bale materials and purity of variety even during transport and the Storage of the packed bale guaranteed. When unpacking the bale, the stretch hoods can very easily be removed separately and before fixing, without material residues of the packaging remaining on the pressed bale. As a result, contamination of the pressed bale material is excluded by the packaging material.
Die Überzieheinrichtung kann eine Dehnhaube zunächst auf ein Übermaß dehnen und dann durch ein Überfahren des Pressballens und einen Abrollvorgang über den Pressballen an zumindest drei Seiten stülpen. Beim Überstülpen legt sich das elastisch schrumpfende Dehnhaubenmaterial dicht an die Ballenoberfläche an. Mittels einer geeigneten Herstellvorrichtung kann die Dehnhaube innerhalb der Verpackungseinrichtung aus einem Folienschlauch in besonders kostengünstiger Weise hergestellt werden. Hierbei können zur Anpassung an unterschiedliche Ballenformate die Haubenabmessungen variiert werden.The overdrawing device may first stretch an expansion hood to an excess and then slip it over at least three sides by overrunning the press bale and rolling over the press bale. When slipping over, the elastically shrinking stretch hood material lays tight against the bale surface. By means of a suitable manufacturing device, the Dehnhaube can be made within the packaging device of a film tube in a particularly cost-effective manner. Here, the hood dimensions can be varied to adapt to different bale formats.
Die erfindungsgemäße Verpackungstechnik kann bei neuen Ballenpressen oder Ballenpressanlagen zum Einsatz kommen. Sie lässt sich auch an bestehenden Ballenpressen und Ballenpressanlagen nachrüsten und gegen vorhandene Verpackungseinrichtungen tauschen. Hierbei kann auch die Ballenlogistik umgerüstet werden, um von einer pressengebundenen Ballenverpackung zu einer zentralen Ballenverpackung zu kommen. Die mit der erfindungsgemäßen Verpackungstechnik verbundenen Kostenvorteile tragen die Investitionen.The packaging technique according to the invention can be used in new balers or baling plants. It can also be retrofitted to existing balers and baling systems and replaced with existing packaging equipment. Here, the bale logistics can be converted to come from a press-tied bale wrapper to a central bale wrapper. The cost advantages associated with the packaging technology according to the invention carry the investment.

Die Erfindung betrifft eine Verpackungseinrichtung (1) und ein Verpackungsverfahren für hochverdichtete Pressballen (2). Die Erfindung betrifft ferner eine mit mindestens einer solchen Verpackungseinrichtung (1) ausgerüstete Ballenpresse (6) oder eine Ballenpressanlage (5) mit ein oder mehreren Ballenpressen (6).The invention relates to a packaging device (1) and a packaging method for highly compressed pressed bales (2). The invention further relates to a baler (6) equipped with at least one such packaging device (1) or a baling plant (5) with one or more balers (6).
Als Ballenmaterial kommen unterschiedliche Werkstoffe in Betracht. Dies können z.B. Faserwerkstoffe, insbesondere Kunstfasern in geschnittener Form als sog. Stapelfasern oder in längerer Form als sog. Tow sein. Alternativ kann das Ballenmaterial aus Naturfasern, z.B. Baumwolle oder dgl., in geschnittener oder in langer Form bestehen. Auch Zellstoff ist geeignet. Ferner können Abfälle, z.B. Textilabfälle aus einer Reissanlage, aber auch andere Materialien, bevorzugt Kleinteile, zum Einsatz kommen. Dies können auch pflanzliche Materialien sein.As bale material different materials come into consideration. This can e.g. Fiber materials, in particular synthetic fibers in a cut form as so-called staple fibers or in a longer form than so-called tow. Alternatively, the bale material may be made from natural fibers, e.g. Cotton or the like, in cut or long form. Also pulp is suitable. Furthermore, waste, e.g. Textile waste from a rice plant, but also other materials, preferably small parts, are used. These can also be herbal materials.
Das Ballenmaterial wird in der Ballenpresse (6) verdichtet und zu einem Pressballen (2) geformt. Die Ballenpressen (6) können zu diesem Zwecke in beliebig geeigneter Weise als Vertikal- oder Horizontalpresse ausgebildet sein, z.B. entsprechend der
Die hochverdichteten Pressballen (2) können mit einer Fixierung (3) versehen sein, die ihnen eine dauerhafte Form gibt und ein Aufspringen der entlasteten Pressballen (2) vor der nachfolgenden Verpackung verhindert. Die Fixierung (3) kann z.B. aus ein oder mehreren Umreifungen mit Kunststoff- oder Stahlbändern bestehen, die während der Ballenverpressung um den Pressballen (2) geschlungen werden. Alternativ sind auch andere Fixierungen möglich. Die Fixierung (3) kann außerdem wahlweise innerhalb der Ballenpresse (6) oder außerhalb mit einer entsprechenden Zusatzeinrichtung angebracht werden.The highly compacted pressed bales (2) can be provided with a fixation (3) which gives them a permanent shape and prevents them from popping up of the unloaded pressed bales (2) before the subsequent packaging. The fixation (3) may e.g. consist of one or more strapping with plastic or steel straps that are wrapped around the pressed bale (2) during baling. Alternatively, other fixations are possible. The fixation (3) can also optionally be mounted within the baler (6) or outside with a corresponding attachment.
In der gezeigten Ausführungsform sind die Ballenpressen (6) über eine Fördereinrichtung (7) mit einer gemeinsamen Verpackungseinrichtung (1) verbunden. In Abwandlung der gezeigten Ausführungsform kann jede Ballenpresse (6) eine eigene Verpackungseinrichtung (1) haben. Ferner können auch innerhalb der Ballenpressanlage (5) Pressengruppen gebildet werden, denen jeweils eine Verpackungseinrichtung (1) zugeordnet ist. In der gezeigten Ausführungsform und den vorgenannten Varianten ist die Verpackungseinrichtung (1) außerhalb der ein oder mehreren Ballenpressen (6) angeordnet. In einer weiteren Abwandlung kann die Verpackungseinrichtung (1) auch in eine Ballenpresse (6) integriert werden, wobei die Ballenpresse (6) z.B. als Karussellpresse oder ähnlich wie in der
Die Verpackungseinrichtung (1) bringt eine Schrumpfverpackung in Form von mindestens einer Dehnhaube (4) auf dem Pressballen (2) an und weist hierfür eine Überzieheinrichtung (16) auf. Die Dehnhaube (4) besteht aus einem dehnelastischen Material, welches nach einem Dehnen von selbst wieder elastisch schrumpfen kann. Das Haubenmaterial kann z.B. ein dehnelastischer Kunststoff, insbesondere ein Polyethylen sein. Besonders günstig sind Kunststofffolien aus einem langkettigen Low-Density-Polyethylen, insbesondere LLDPE. Es können dehnbare Kunststofffolien für eine Schrumpffolienverpackung eingesetzt werden.The packaging device (1) applies a shrink wrap in the form of at least one expansion hood (4) on the press bale (2) and has for this purpose a coating device (16). The Dehnhaube (4) consists of a stretch-elastic material, which can shrink elastically after stretching itself again. The hood material may e.g. a stretch-elastic plastic, in particular a polyethylene. Plastic films made of a long-chain low-density polyethylene, in particular LLDPE, are particularly favorable. Stretchable plastic films can be used for shrink wrap packaging.
Werden die Dehnhauben (4) nach der Fixierung und außerhalb der Ballenpresse (6) aufgebracht, braucht das dehnelastische Material vorteilhafter Weise die beim Expandieren des Pressballens während der Entlastung in der Presse auftretenden Lokalkräfte und Lokaldehnungen nicht mitzumachen, die insbesondere zwischen den Fixierungen bzw. Umreifungen (8) auftreten. Das Verpackungsmaterial muss daher keine besonders hohe Zugefestigkeit aufweisen. Es können beispielsweise preisgünstige, dünne und homogene Kunststofffolien verwendet werden, die nicht über eingearbeitete Stützfasern oder -netze verfügen.If the Dehnhauben (4) applied after fixing and outside the baler (6), the elastic-elastic material advantageously does not need to join the local forces and Lokaldehnungen occurring during expansion of the press bale during discharge in the press, in particular between the fixations or strapping (8) occur. The packaging material therefore does not have to have a particularly high tensile strength. For example, low cost, thin and homogenous plastic films can be used that do not have incorporated support fibers or meshes.
Die Dehnhaube (4) hat eine sackähnliche Form mit einer Öffnung (32), einem geschlossenen Boden (33) und einem Mantel (34). Die Dehnhaube (4) kann in beliebig geeigneterThe expansion hood (4) has a bag-like shape with an opening (32), a closed bottom (33) and a jacket (34). The Dehnhaube (4) can in any suitable
Weise hergestellt und auf dem Pressballen (2) appliziert werden. Vorzugsweise wird sie mit ihrer abgelängten Sackform vor der Applikation an den Pressballen (2) gebildet, gerefft und vorgedehnt und danach über den Pressballen (2) gestülpt. Die Länge der Dehnhaube (4) kann kürzer als die zu bedeckende Ballenlänge sein, so dass der Pressballen (2) nicht vollständig von der Dehnhaube (4) umschlossen wird und durch die Haubenöffnung (32) ragt.Be prepared and applied to the pressed bale (2). Preferably, it is formed with its cut-sack shape before application to the pressed bale (2), reefed and pre-stretched and then slipped over the pressed bales (2). The length of the expansion hood (4) can be shorter than the bale length to be covered, so that the pressed bale (2) is not completely enclosed by the expansion hood (4) and projects through the hood opening (32).
Der üblicherweise längliche Pressballen (2) kann beim Anbringen der Dehnhaube (4) eine beliebig geeignete Lage haben. Dies kann z.B. eine liegende Lage wie in
Die Verpackungseinrichtung (1) weist eine Ballenaufnahme (20) an der Verpackungsstelle auf, die auf die Formgebung und die Handhabungserfordernisse eines Pressballens (2) angepasst ist und eine ausreichende Stabilität aufweist. Sie kann in einen Förderer eingebunden sein. Außerdem kann an der Ballenaufnahme (20) eine Stabilisierungseinrichtung (29) angeordnet sein, die den Pressballen (2) in einer vorgegebenen und verpackungsgünstigen Lage positioniert und stabil hält. Die Stabilisierungseinrichtung (29) kann insbesondere einen mit seiner Längsachse aufrecht stehenden Pressballen (2) stabilisieren und gegen Umfallen sichern.The packaging device (1) has a bale receptacle (20) at the packaging location, which is adapted to the shaping and the handling requirements of a press bale (2) and has sufficient stability. It can be integrated into a conveyor. In addition, a stabilizing device (29) can be arranged on the ball receptacle (20) which positions and keeps the pressed bale (2) in a predetermined and packaging-favorable position. In particular, the stabilization device (29) can stabilize a press bale (2) standing upright with its longitudinal axis and secure it against falling over.
Die Überzieheinrichtung (16) ist vorzugsweise derart ausgestaltet, dass sie die vorbereitete Dehnhaube (4) auf ein Übermaß weitet und über den auf der Ballenaufnahme (20) bereitstehenden Pressballen (2) stülpt. Hierbei kann die Dehnhaube (4) mit dem geschlossenen Boden (33) zum Ballen (2) hin bzw. nach unten und mit der Haubenöffnung (32) vom Ballen (2) weg bzw. nach oben weisen, wobei die Dehnhaube (4) beim Überstülpen über den Pressballen (2) mit dem geschlossenen Boden (33) zuerst auf der Ballenoberseite aufgelegt wird und anschließend umgeklappt oder gewendet wird, wobei die Haubenseitenwände (34) abgerollt und beim Umbiegen an die Ballenseitenwände angelegt werden. Beim Dehnen des Haubenmaterials können sowohl der Bodenbereich (33) in der horizontalen Ebene, als auch die seitlichen Haubenwände (34) in der Vertikalen gedehnt werden. Die Längs- und Umfangsdehnungen der Dehnhaube (4) können separat und weitgehend unabhängig voneinander eingestellt werden.The overdrawing device (16) is preferably configured such that it expands the prepared expansion hood (4) to an excess and turns it over the press bale (2) which is provided on the bale receiver (20). Here can the expansion hood (4) with the closed bottom (33) for bale (2) towards or down and with the hood opening (32) from the bale (2) away or upwards, the Dehnhaube (4) when slipping over the pressed bale (2) with the closed bottom (33) is first placed on the bale top and is then folded or turned, wherein the hood side walls (34) are unrolled and applied to the bale side walls when bending. When the hood material is stretched, both the bottom region (33) in the horizontal plane and the lateral hood walls (34) can be stretched in the vertical direction. The longitudinal and circumferential strains of the expansion hood (4) can be adjusted separately and largely independently.
Die Überzieheinrichtung (16) kann z.B. gemäß der
Bei der bevorzugten und in
Am Dehnrahmen (18) und insbesondere an den Eckteilen kann eine Reffeinrichtung (19) mit Reibrollen angeordnet sein, welche die Seitenwände (34) der Dehnhaube (4) hochzieht, dabei unter Verkürzung der Mantellänge faltet bzw. rafft und in die in
Die Dehnhauben (4) können in beliebig geeigneter Weise vorbereitet und bereit gestellt werden. In der gezeigten Ausführungsform besitzt die Überzieheinrichtung (16) eine Herstellvorrichtung (17) für die Dehnhauben (4), die aus einem Stretchfolienschlauch (30) gebildet werden. Die Haubenbildung erfolgt hierbei unmittelbar vor der Haubenapplikation auf dem Ballen (2). Der stirnseitig offene Schlauch (30) wird hierbei von einem neben der Ballenaufnahme (20) angeordneten Coil (36) mit einer Greifeinrichtung vorzugsweise vertikal nach oben abgezogen und auf die vorgesehene Länge gebracht, wobei eine Schneid- und Schweißeinrichtung (31,41,42) den gestreckten Schlauch (30) am unteren Ende durchtrennt.The Dehnhauben (4) can be prepared in any suitable manner and provided. In the illustrated embodiment, the overdrawing device (16) has a manufacturing device (17) for the Dehnhauben (4), which are formed from a stretch film tube (30). The hood formation takes place here immediately before the hood application on the bale (2). In this case, the tube (30), which is open at the end, is pulled off vertically from above by a coil (36) arranged next to the bale holder (20) with a gripping device and brought to the intended length, wherein a cutting and welding device (31,41,42) cuts through the stretched tube (30) at the lower end.
Die Schlauchöffnung des abgetrennten Schlauchstücks (30') wird an der Trennstelle mit einer Schweißnaht oder in anderer geeigneter Weise unter Bildung des Bodens (33) verschlossen. Das einseitig unten geschlossene Schlauchstück (30') befindet sich unterhalb des Dehnrahmens (18) seitlich neben dem Pressballen (2) und bildet die Dehnhaube (4). Der Schlauch (30) hat dabei einen Umfang und eine Weite, die kleiner als der Umfang und die Weite des Pressballens (2) sind, so dass die übergestülpte Dehnhaube (4) nach dem Schrumpfen immer noch gedehnt ist und dadurch elastisch und dicht am Pressballen (2) anliegt.The tube opening of the severed piece of tubing (30 ') is sealed at the point of separation with a weld or other suitable means to form the bottom (33). The tube piece (30 ') closed on one side below is located below the stretching frame (18) laterally next to the pressed bale (2) and forms the expansion hood (4). The tube (30) has a circumference and a width which are smaller than the circumference and the width of the press bale (2), so that the slipped-over Dehnhaube (4) is still stretched after shrinking and thereby elastic and close to the pressed bale (2) is present.
Das Handling des Schlauchs (30) und des abgetrennten Schlauchstücks (30') ist beispielhaft in den
Die Herstellvorrichtung (17) zieht im Übergang von der Abziehstellung (A) zur Zuführstellung (B) mit bevorzugt vier zugestellten Fingern (37) die obere Schlauchöffnung auseinander und bildet eine im Querschnitt der Kontur des zusammengefahrenen Dehnrahmens (18) entsprechende Dehnhaubenöffnung (32). Die Finger (37) übergeben anschließend die geöffnete Dehnhaube (4) von unten her an den eingefahrenen Dehnrahmen (18), wobei die Dehnhaube (4) bzw. das Schlauchstück (30') sich mit Luft füllt, aufbläht und entfaltet. Der Dehnrahmen (18) und/oder ein Schlitten (38) mit den Fingern (37) können Seitenbewegungen und Hubbewegungen ausführen. Am Dehnrahmen (18) wird die übergebene Dehnhaube (4) mit der Reffeinrichtung (19) außenseitig aufgenommen und balgartig an der Seitenwandung des Dehnrahmens (18) aufgefaltet und anschließend durch ein Spreizen des Dehnrahmens (18) noch weiter auf das zum Überstülpen benötigte Maß gedehnt. Die Innenfläche des gespreizten Dehnrahmens (18) ist etwas größer als die Ballenstirnfläche.The manufacturing device (17) moves in the transition from the peeling position (A) to the feed position (B) with preferably four added fingers (37) apart the upper tube opening and forms a cross-section of the contour of the contracted Dehnrahmens (18) corresponding Dehnhaubenöffnung (32). The fingers (37) then transfer the opened expansion hood (4) from below to the retracted expansion frame (18), wherein the expansion hood (4) or the hose piece (30 ') fills with air, inflates and deploys. The Dehnrahmen (18) and / or a carriage (38) with the fingers (37) can perform side movements and strokes. On Dehnrahmen (18) the transferred Dehnhaube (4) with the Reffeinrichtung (19) is taken on the outside and bellows on the side wall of the Dehnrahmens (18) unfolded and then further stretched by spreading the Dehnrahmens (18) to the extent required for slipping , The inner surface of the expanded stretch frame (18) is slightly larger than the bale end face.
Die Dehnhaube (4) weist mit ihrem Boden (33) zum Ballen (2) hin und mit ihrer Öffnung (32) vom Ballen (2) weg. Bei der Relativbewegung zwischen Dehnrahmen (18) und Ballen (2) trifft zuerst der Boden (33) mit seiner Außenseite auf den Ballen (2), wobei während der Weiterbewegung die Dehnhaube (4) umgeklappt und gewendet wird. Die ursprünglich oben befindliche Haubenöffnung (32) liegt am Ende der Aufzieh- und Stülpbewegung unten. Während der Relativbewegung wird der gereffte Mantelbereich (34,35) vom Dehnrahmen (18) nach und nach abgezogen und am unteren Dehnrahmenrand bzw. der dortigen Abroll- oder Wendekante um 180° umgelenkt sowie an die Ballenseitenwand schrumpfend angelegt.The expansion hood (4) points with its bottom (33) towards the bale (2) and with its opening (32) away from the bale (2). In the relative movement between Dehnrahmen (18) and bale (2) first hits the bottom (33) with its outside on the bale (2), wherein during the further movement of the Dehnhaube (4) is folded and turned. The hood opening (32), which was originally located at the top, is at the bottom at the end of the winding and staggering movement. During the relative movement of the reefed jacket portion (34,35) from the Dehnrahmen (18) gradually withdrawn and deflected at the lower Dehnrahmenrand or the local unwinding or turning edge by 180 ° and applied shrinking to the bale side wall.
Beim Überstülpen der Dehnhaube (4) kann der Abstand zwischen dem Dehnrahmen (18) und den Seiten des Pressballens (2) sehr klein gewählt werden. Hierdurch kann die Dehnhaube (4) mit einer großen Restdehnung und den damit verbundenen größeren Anlagekräften auf dem Pressballen (2) aufgebracht werden, was für die Haltbarkeit der Verpackung vorteilhaft ist. Die Seitenwände (34) der Dehnhaube (4) werden während des gesamten Überziehvorganges um den Dehnrahmen (18) geführt und können auch zum Ende des Überziehvorganges mit den Materialkanten auf dem Pressballen angelegt werden, was eine kontrollierte Längsdehnung des Haubenmaterial über die gesamte seitliche Anlagefläche ermöglicht. Ein unkontrolliertes Aufschnappen der Dehnhaube (4) am Ende des Überziehvorganges kann verhindert werden, was eine höhere Genauigkeit bei der Positionierung der Dehnhaube ermöglicht.When slipping over the Dehnhaube (4), the distance between the Dehnrahmen (18) and the sides of the press bale (2) can be chosen very small. As a result, the expansion hood (4) can be applied to the press bale (2) with a large residual elongation and the associated greater contact forces, which is advantageous for the durability of the packaging. The side walls (34) of the Dehnhaube (4) are guided during the entire coating process to the Dehnrahmen (18) and can also be applied to the end of the coating process with the material edges on the pressed bale, which allows a controlled longitudinal expansion of the hood material over the entire lateral contact surface , An uncontrolled snapping the Dehnhaube (4) at the end of the coating process can be prevented, which allows a higher accuracy in the positioning of the Dehnhaube.
Die Verpackungseinrichtung (1) kann in der einfachsten Variante den Pressballen (2) mit einer einzelnen Dehnhaube (4) umgeben, wobei zumindest ein Teilbereich des Pressballens (2) unbedeckt oder frei bleibt.In the simplest variant, the packaging device (1) can surround the pressed bale (2) with a single expansion hood (4), wherein at least a portion of the bale press (2) remains uncovered or free.
Die Verpackungseinrichtung (1) ermöglicht alternativ die Bildung einer vollständigen Umhüllung oder Verpackung (26) des Pressballens (2). Die Umhüllung (26) kann aus mehreren Dehnhauben (4) bestehen, die von verschiedenen, z.B. von gegenüber liegenden, Seiten und mit gegenseitiger Überlappung um den Pressballen (2) gelegt werden. Alternativ kann der Pressballen (2) bereits eine Teilumhüllung (11) aufweisen, z.B. eine Bodenfolie, die den Boden und die abgrenzenden Seitenwände bis zu einer gewissen Höhe dicht umschließt. Diese Teilumhüllung (11) wird nachfolgend näher erläutert.The packaging device (1) alternatively allows the formation of a complete envelope or package (26) of the press bale (2). The envelope (26) may consist of several expansion hoods (4), which are of different, for example, from opposite sides and with mutual overlap around the pressed bale (2) are placed. Alternatively, the pressed bale (2) may already have a partial covering (11), eg a bottom foil, which tightly encloses the bottom and the delimiting side walls up to a certain height. This Teilumhüllung (11) is explained in more detail below.
Wenn der Pressballen (2) in mehrere Dehnhauben (4) eingepackt werden soll, weist die Verpackungseinrichtung (1) eine Wendeeinrichtung (21) für Pressballen (2) auf. Die Wendeeinrichtung (21) kann in unterschiedlicher Weise ausgebildet sein und z.B. den Pressballen (2) auf der Ballenaufnahme (20) ein oder mehrmals und ggf. nach verschiedenen Richtungen wenden.If the pressed bale (2) is to be packed in a plurality of expansion hoods (4), the packaging device (1) has a turning device (21) for pressed bales (2). The turning device (21) may be formed in different ways and e.g. Turn the pressed bale (2) on the bale holder (20) one or more times and, if necessary, in different directions.
Im gezeigten Ausführungsbeispiel hat die Wendeeinrichtung (21) aus Zeit- und Kapazitätsgründen eine andere Ausgestaltung und besteht aus einem Förderer (22), der die Verpackungseinrichtung (1) umschließt und im wesentlichen U-förmig ausgebildet ist, wobei er mit seinen Enden vor und hinter der Verpackungseinrichtung (1) an einen dortigen Förderer (13) angeschlossen ist. Am Förderer (22) sind ein oder mehrere Kippvorrichtungen (23) für einen Pressballen (2) angeordnet, die sich z.B. an den Eckstellen des Förderers (22) befinden und dort den vom einen Förderast ankommenden Pressballen (2) umkippen und dabei auf den im Winkel anschließenden nächsten Förderast kippen.

Wie
Hinter der Verpackungseinrichtung (1) kann eine weitere Überwachungseinrichtung (28) angeordnet sein, welche die Verpackungsqualität prüft und insbesondere feststellt, ob die ein oder mehreren Dehnhauben (4) dicht um den Pressballen (2) schließen oder ob sie aufgebrochen oder aufgetrennt sind. In einem solchen Fall kann der Pressballen (2) über einen geeigneten Zusatzförderer (nicht dargestellt) wieder in den Zuführbereich (24) zurückgebracht und erneut der Verpackungseinrichtung (1) zugeführt werden.Behind the packaging device (1), a further monitoring device (28) can be arranged, which checks the packaging quality and in particular determines whether the one or more Dehnhauben (4) close tightly around the pressed bale (2) or if they are broken or separated. In such a case, the pressed bale (2) can be returned to the feed area (24) via a suitable additional conveyor (not shown) and returned to the packaging device (1).
Wenn in einer einzelnen Ballenpresse (6) oder in einer Ballenpressanlage (5) mit mehreren Ballenpressen (6) verschiedene Ballenmaterialien verarbeitet werden, die aus Qualitätsgründen sortenrein gehalten werden sollen, kann ein Verschleppungsproblem im Zuführbereich (24) bestehen. Während des Ballentransports können sich durch Abrieb oder dgl. Ballenpartikel lösen und im Förderbereich ablegen, wo sie unter Umständen von einem anderen Pressballen aus einem anderen Material wieder aufgenommen werden können und dann die unerwünschte Verunreinigung oder eine Materialvermischung bilden. Dem kann durch eine Einrichtung (15) zur Vermeidung von Verunreinigungen und/oder Vermischungen von Ballenmaterialien begegnet werden, die bevorzugt der Verpackungseinrichtung (1) zugeordnet ist. Die Einrichtung (15) kann in unterschiedlicher Weise ausgebildet sein.If in a single baler (6) or in a baler (5) with multiple balers (6) different bale materials are processed, which should be kept sorted for quality reasons, there may be a carryover problem in the feed (24). During the bale transport, bales of particles may be released by abrasion or the like and deposited in the conveying area, where they may possibly be taken up again by another bale of another material and then form the undesired contamination or a mixture of materials. This can be counteracted by a device (15) for avoiding contamination and / or mixing of bale materials, which is preferably associated with the packaging device (1). The device (15) can be designed in different ways.
In einer weiteren Variante der Einrichtung (15) können die Pressballen (2) bereits frühzeitig und vor Aufgabe an den Zuführbereich (24) mit der eingangs erwähnten Teilumhüllung (11) versehen werden. Dies kann z.B. die genannte Bodenhülle oder Bodenfolie sein, die während der Ballenherstellung bereits eingebracht wird und den Pressballen (2) zumindest an der Unterseite und vorzugsweise auch an einem Teilbereich der angrenzenden Ballenseitenwände schützend und dicht bedeckt. Die Teilumhüllung (11) kann von der Umreifung oder einer anderen Fixierung (3) außenseitig umgeben und am Pressballen (2) festgehalten werden.In a further variant of the device (15), the pressed bales (2) can be provided with the partial covering (11) mentioned in the introduction at an early stage and prior to the task on the feed region (24). This can e.g. be said soil cover or bottom sheet, which is already introduced during the bale production and the pressed bales (2) at least on the underside and preferably also on a portion of the adjacent bale sidewalls protective and tightly covered. The partial covering (11) can be surrounded on the outside by the strapping or another fixation (3) and held fast on the pressed bale (2).
Zur Anbringung der Teilumhüllung (11) weist die Verpackungseinrichtung (1) eine Vorverpackungseinrichtung (10) auf, die einen oder mehreren Ballenpressen (6) zugeordnet ist. Die Vorverpackungseinrichtung (10) kann z.B. entsprechend der
Abwandlungen der gezeigten und beschriebenen Ausführungsformen sind in verschiedener Weise möglich. Die Verpackungseinrichtung (1) kann konstruktiv anders ausgebildet und an anderer Stelle positioniert sein. Die Dehnhauben (4) können anderweitig hergestellt und bereit gestellt werden. Die Dehnhauben (4) können auch auf andere Weise auf dem Pressballen (2) appliziert werden. Das Überstülpen der beschriebenen Art hat allerdings den Vorteil, dass die Schweißnaht am Haubenboden sich an der Innenseite befindet und zum Pressballen (2) gekehrt ist. Sie ist dadurch gegen negative Einwirkungen von außen gesichert. Ferner können die Ballenpressen (6) in beliebig anderer Weise konstruktiv ausgebildet und angeordnet sein. Die Kinematik der Relativbewegung von Pressballen (2) und Dehnhaube (4) kann variiert werden, indem bei der Haubenapplikation beide relativ zueinander bewegt werden oder alternativ der Pressballen (2) relativ zur ruhenden Dehnhaube (4) und dem ruhenden Dehnrahmen (18) bewegt wird. Auch das Dehnhaubenmaterial kann variieren und muss keine Kunststofffolie sein.Variations of the embodiments shown and described are possible in various ways. The packaging device (1) may be structurally different and positioned elsewhere. The Dehnhauben (4) can be made elsewhere and provided. The stretch hoods (4) can also be applied to the pressed bale (2) in other ways. However, the slipping of the type described has the advantage that the weld on the hood bottom is located on the inside and the pressed bale (2) is swept. It is thus protected against negative external influences. Furthermore, the balers (6) can be structurally designed and arranged in any other way. The kinematics of the relative movement of pressed bale (2) and expansion hood (4) can be varied by both are moved relative to each other in the hood application or alternatively the pressed bale (2) is moved relative to the stationary expansion hood (4) and the stationary expansion frame (18). Also, the Dehnhaubenmaterial can vary and does not have to be plastic film.
