Description

Die Erfindung betrifft eine Abfüllanlage für Behälter gemäß Oberbegriff des Anspruchs 1 und wie bekannt aus EP 2 439 048 A1 sowie ein Verfahren zum Betreiben der Abfüllanlage.The invention relates to a filling system for containers according to the preamble of claim 1 and as known from EP 2 439 048 A1 and a method for operating the bottling plant.

Abfüllanlagen für Getränke oder dergleichen umfassen bekanntermaßen mehrere hintereinander geschaltete Produktionseinheiten, wie beispielsweise Füllmaschinen, Etikettiermaschinen und Verpackungsmaschinen. Diese können, wie beispielsweise in der DE 10 2009 040 977 A1 beschrieben ist, zumindest teilweise als Rundläufermaschinen ausgebildet sein, die mittels rotierender Übergabevorrichtungen aneinander gekoppelt sind. Alternativ können die Produktionseinheiten auch als Geradläufer ausgebildet sein und/oder über lineare Transporteinrichtungen, Verteileinrichtungen und Produktpuffer miteinander verbunden sein. Entsprechende Anlagenkonzepte sind beispielsweise in der DE 4 442 586 W4, der DE 20 2004 012 848 U1 und der EP 2 218 664 A2 beschrieben.Bottling plants for beverages or the like are known to comprise a plurality of production units connected in series, such as filling machines, labeling machines and packaging machines. These can, as in the DE 10 2009 040 977 A1 is described, at least partially designed as a rotary machines, which are coupled by means of rotating transfer devices to each other. Alternatively, the production units may also be configured as straight-line machines and / or connected to one another via linear transport devices, distribution devices and product buffers. Corresponding plant concepts are for example in the DE 4 442 586 W4, the DE 20 2004 012 848 U1 and the EP 2 218 664 A2 described.

Bekannte Abfüllanlagen sind jedoch meistens hinsichtlich einer Maximierung der Anlagenleistung für einen bestimmten Behältertyp optimiert. Formatwechsel auf andere Behältertypen lassen sich dann, falls überhaupt, meist nur mit großem technischen und zeitlichen Aufwand bewerkstelligen.However, known bottling plants are mostly optimized for maximizing plant performance for a particular type of bin. Format changes to other container types can then be accomplished, if at all, usually only with great technical and temporal effort.

Um dem zunehmenden Bedarf für eine Diversifikation von Behältern und deren Ausstattungsvarianten zu begegnen, schlägt beispielsweise die EP 1 299 304 B1 vor, einen komplexen und variablen Anlagenbetrieb durch Zwischenspeichern, insbesondere ein Palettieren, der Produkte zwischen dem Verschließen und dem Verpacken der Behälter zu ermöglichen. Derartige Anlagenkonzepte sind zwar flexibel, verursachen jedoch einen erhöhten Platzbedarf. Außerdem können Standardbehälter mit rundem Querschnitt in der Regel trotzdem nicht in der gleichen Anlagenlinie gefahren werden wie Formflaschen mit eckigen oder ovalen Querschnitten. Es sind daher zumindest Abschnitte der Abfüllanlage für die diese Behältertypen getrennt auszulegen, was zusätzlichen Platzbedarf sowie hohe Investitions- und Betriebskosten verursacht.To meet the increasing demand for diversification of containers and their equipment variants, suggests, for example, the EP 1 299 304 B1 to enable complex and variable plant operation by caching, in particular palletizing, the products between the closing and the packaging of the containers. Such system concepts are flexible, but cause an increased space requirement. In addition, standard containers with a round cross-section can generally not be driven in the same line as rectangular or oval shaped bottles. Therefore, at least sections of the bottling plant for which these types of containers are to be designed separately, which causes additional space requirements and high investment and operating costs.

Es besteht somit der Bedarf für eine Abfüllanlage, die unterschiedliche Behältertypen bei geringem Platzbedarf effizient verarbeiten kann. Ebenso sind Betriebsverfahren erwünscht, die eine schnelle Umstellung bei Produktwechseln und geringe Ausfallzeiten bei Betriebsstörungen ermöglichen.Thus, there is a need for a bottling plant that can efficiently handle different types of containers with a small footprint. Likewise, operating methods are desired which allow rapid changeover with product changes and short downtime in case of malfunction.

Die gestellte Aufgabe wird mit einer Abfüllanlage gemäß Anspruch 1 gelöst. Diese umfasst demnach eine Füllmaschine zum Befüllen der Behälter, wenigstens eine Verpackungsmaschine zum Verpacken der befüllten Behälter sowie eine steuerbare Verteileinrichtung zum Verteilen der befüllten Behälter auf wenigstens zwei getrennt steuerbare und in Richtung der Verpackungsmaschine verlaufende Transportstrecken. Erfindungsgemäß sind die Transportstrecken für den drucklosen Behältertransport ausgebildet und umfassen jeweils wenigstens einen einspurigen Behälterpuffer.The stated object is achieved with a filling system according to claim 1. This therefore comprises a filling machine for filling the containers, at least one packaging machine for packing the filled containers and a controllable distributor device for distributing the filled containers on at least two separately controllable and extending in the direction of the packaging machine transport paths. According to the invention, the transport paths are designed for the unpressurised container transport and each comprise at least one single-lane container buffer.

Aufgrund der drucklosen Behälterführung lassen sich sowohl Standardbehälter mit rundem Querschnitt als auch Behälter mit nicht rundem Querschnitt, wie beispielsweise Formflaschen mit eckigen oder ovalen Querschnitten, in der Abfüllanlage transportieren und puffern. Unter einer drucklosen Förderung und Pufferung der Behälter ist hierbei eine Führung ohne schädlichen Staudruck zu verstehen, so dass die Behälter beim Transport und Puffern nicht derart aufeinanderdrücken, dass sich eine vorgegebene Orientierung und/oder Reihenfolge der Behälter entlang der Transportstrecke und des Puffers ändert. Insbesondere ist damit gemeint, dass sich die Drehlage von Behältern mit nicht rundem Querschnitt derart ändert, dass sich die Behälter gegenseitig oder an Führungselementen der Produktionseinheiten verkeilen können.Due to the pressure-free container guide, both standard containers with a round cross-section and containers with non-round cross-section, such as, for example, shaped bottles with angular or oval cross-sections, can be transported and buffered in the bottling plant. Unpressurized pumping and buffering of the containers here means a guide without harmful back pressure, so that the containers do not press against each other during transport and buffering in such a way that a predetermined orientation and / or order of the containers changes along the transport path and the buffer. In particular, this means that the rotational position of containers of non-round cross section changes in such a way that the containers can wedge against each other or on guide elements of the production units.

Die zu befüllenden Behälter sind insbesondere Getränkeflaschen. Die Abfüllanlage eignet sich jedoch ebenso zum Befüllen von Behältern mit Haushaltsmitteln, Medikamenten, Hygieneartikeln oder dergleichen. Die befüllten Behälter werden vorzugsweise zu Behältergebinden verpackt. Die Steuerung der Verteileinrichtung erfolgt in bekannter Weise über eine zentrale Steuereinheit, insbesondere auf Grundlage von Statusmeldungen stromabwärts von der Verteileinrichtung vorgesehener Produktionseinheiten.The containers to be filled are in particular beverage bottles. However, the bottling plant is also suitable for filling containers with household funds, medicines, toiletries or the like. The filled containers are preferably packaged into container containers. The control of the distribution device takes place in a known manner via a central control unit, in particular based on status messages downstream of the distribution unit provided production units.

Mit Hilfe der wenigstens in doppelter Ausführung vorgesehenen Transportstrecken lassen sich stromabwärts vorgesehene Produktionseinheiten, wie beispielsweise Etikettiermaschinen, Schrumpftunnel oder dergleichen trotz einer drucklosen und zumindest abschnittsweise einspurigen Förderung der Behälter mit einer vergleichsweise hohen Maschinenleistung und großer Ausfallsicherheit betreiben.With the help of at least provided in duplicate transport routes can be operated downstream production units, such as labellers, shrink tunnel or the like despite a non-pressurized and at least partially single-lane promotion of the container with a comparatively high engine power and high reliability.

Vorzugsweise ist die Füllmaschine zum Befüllen von Behältern mit rundem Querschnitt, nachfolgend der Einfachheit halber auch Standardbehälter genannt, und nicht rundem Querschnitt, nachfolgend der Einfachheit halber auch Formbehälter genannt, ausgebildet. Dies ermöglicht eine einfache Umstellung der Abfüllanlage beim Formatwechsel des Behältertyps. Es könnten jedoch auch getrennte Füllmaschinen für Standardbehälter und Formbehälter vorgesehen sein. Die unterschiedlichen Behältertypen können dann nichtsdestoweniger der steuerbaren Verteileinrichtung zugeführt werden.Preferably, the filling machine for filling containers with a round cross-section, hereinafter also called standard container for the sake of simplicity, and not round cross-section, hereinafter also referred to as simplicity form container, formed. This allows a simple conversion of the filling system during format change of the container type. However, separate filling machines for standard containers and mold containers could also be provided. The different types of containers can then nevertheless be supplied to the controllable distributor.

Vorzugsweise sind in den Transportstrecken stromabwärts der Behälterpuffer Etikettiermaschinen, insbesondere Sleeve-Aggregate, vorgesehen. Etikettiermaschinen, insbesondere Sleeve-Aggregate, haben in der Regel eine geringere Maschinenleistung als Füllmaschinen. Die Maschinenleistung der Abfüllanlage insgesamt kann optimiert werden, indem die Etikettiermaschinen wenigstens doppelt vorgesehen sind und parallel betrieben werden können. Die Transportstrecken sind somit ab der Verteileinrichtung parallel geschaltet. Der Produktstrom wird hierbei vorzugsweise gleichmäßig auf die Transportstrecken verteilt. Die Parallelschaltung ermöglicht eine Platz sparende Anordnung, insbesondere mit Etikettiermaschinen nach dem Geradläuferprinzip.Preferably, in the transport sections downstream of the container buffer labeling machines, in particular sleeve units, are provided. Labeling machines, in particular sleeve units, generally have lower machine performance than filling machines. The machine performance of the filling plant as a whole can be optimized by the labeling machines are provided at least twice and can be operated in parallel. The transport routes are thus connected in parallel from the distribution device. The product stream is in this case preferably distributed uniformly over the transport routes. The parallel connection allows a space-saving arrangement, especially with labellers according to the straight-line principle.

Vorzugsweise ist die Verteileinrichtung derart steuerbar, dass sie bei einer Reduzierung der Maschinenleistung, insbesondere einer Produktionsunterbrechung, entlang einer der Transportstrecken die Behälter in den zugehörigen Behälterpuffer leitet, insbesondere nur so lange, bis dieser gefüllt ist, und/oder die Behälter in die wenigstens eine weitere Transportstrecke leitet. Insbesondere erfolgt diese Betriebsweise bei einem Stillstand einer der Etikettiermaschinen oder bei einem Stillstand einer am Ende der Transportstrecke vorgesehenen Verpackungsmaschine.Preferably, the distribution device is controllable such that it leads in a reduction of machine power, in particular a production interruption, along one of the transport lines, the container in the associated container buffer, in particular only until it is filled, and / or the container in the at least one directs further transport route. In particular, this mode of operation takes place at a standstill of one of the labeling machines or at a standstill of a packaging machine provided at the end of the transport path.

Dadurch lässt sich der stromaufwärts der Verteileinrichtung angeordnete Teil der Abfüllanlage trotz des partiellen Stillstands im Wesentlichen bei unverminderter Maschinenleistung weiter betreiben, zumindest solange, bis der Behälterpuffer gefüllt ist. Produktionseinheiten, die einen Betrieb bei im Wesentlichen unveränderter Maschinenleistung voraussetzen, können dann zumindest bis zum vollständigen Befüllen des Behälterpuffers ordnungsgemäß weiter betrieben werden. Dadurch können in diesen Anlagenteilen Produktionsunterbrechungen vermieden oder zumindest reduziert werden, ebenso die zugehörigen Phasen des Herunterfahrens und/oder Hochfahrens der jeweiligen Produktionseinheiten.As a result, the part of the bottling plant arranged upstream of the distributor device can continue to be operated substantially at unimpaired machine output despite the partial standstill, at least until the container buffer is filled. Production units that require operation with essentially unchanged engine power can then continue to be operated properly at least until the tank buffer has been completely filled. As a result, production interruptions can be avoided or at least reduced in these plant parts, as well as the associated phases of shutdown and / or startup of the respective production units.

Ebenso wäre es möglich, die Abfüllanlage nach dem vollständigen Füllen des Behälterpuffers mit reduzierter Maschinenleistung weiter zu betreiben, indem nur die Weiterverarbeitung entlang der von dem Stillstand betroffenen Transportstrecke unterbrochen wird. Entlang der wenigstens einen weiteren Transportstrecke könnten die Behälter dagegen weiterhin ordnungsgemäß weiterverarbeitet werden. Eine derartige Betriebsweise ist insbesondere dann von Vorteil, wenn die stromaufwärts der Verteileinrichtung vorgesehenen Produktionseinheiten, wie beispielsweise die Füllmaschine und/oder eine Blasmaschine mit entsprechend reduzierter, insbesondere halbierter Maschinenleistung betrieben werden können. Auch in diesem Fall könnte ein vollständiges Herunterfahren der jeweiligen Produktionseinheiten vermieden werden.Likewise, it would be possible to continue to operate the bottling plant after the filling of the container buffer with reduced machine power by only the further processing along the transport line affected by the standstill is interrupted. On the other hand, the containers could continue to be processed properly along the at least one further transport route. Such an operating mode is particularly advantageous if the production units provided upstream of the distributing device, such as, for example, the filling machine and / or a blow molding machine, can be operated with correspondingly reduced, in particular halved, engine power. Also in this case, a complete shutdown of the respective production units could be avoided.

Vorzugsweise sind zwischen der Verteileinrichtung und den Etikettiermaschinen gelegene erste Abschnitte der Transportstrecken einspurig. Dies vereinfacht zum einen die drucklose Behälterführung entlang der Transportstrecken und in den Behälterpuffern. Zum anderen vereinfacht eine derartige einspurige Behälterführung den Austausch von Führungselementen bei einem Formatwechsel, insbesondere um einen jeweils verdrehsicheren Transport von Formbehältern unterschiedlicher Größe zu ermöglichen. Insbesondere die Transportstrecken unmittelbar vor und hinter dem Behälterpuffer lassen sich bei Produktwechsel dann besonders schnell und wirtschaftlich umstellen.Preferably, located between the distributor and the labeling first sections of the transport routes are single track. This simplifies the unpressurized container guide along the transport routes and in the container buffers. On the other hand, such a single-track container guide simplifies the replacement of guide elements in the case of a format change, in particular in order to enable a respectively rotationally secure transport of molded containers of different sizes. In particular, the transport distances immediately in front of and behind the container buffer can then be changed particularly quickly and economically when changing products.

Der Behälterpuffer ist vorzugsweise derart ausgelegt, dass eine Verstellung von Führungselementen, wie beispielsweise Führungsgeländer, bei einem Formatwechsel entbehrlich ist. Dies lässt sich beispielsweise durch eine entsprechende Kombination von Förderbändern bewerkstelligen. Vorzugsweise sind zwischen den Etikettiermaschinen und der wenigstens einen Verpackungsmaschine gelegene zweite Abschnitte der Transportstrecken mehrspurig in Form separater Gassen ausgebildet. Dadurch können die Behälter gegen ein Verdrehen gesichert und in einem vorgegebenen Abstand zueinander durch die einzelnen Gassen transportiert werden. Unter den Gassen sind hierbei parallel geschaltete, einspurige Transportwege zu verstehen, die so mechanisch voneinander abgeschirmt sind, dass sich die in benachbarten Gassen transportierten Behälter gegenseitig nicht in ihrer Orientierung und in ihrer Stellung bezüglich des Produktstroms beeinflussen. Derartige einspurige Gassen könnten beispielsweise auf einfache Weise durch Führungsgeländer voneinander abgetrennt werden. Mit Hilfe der separaten Gassen können die Behälter bereits ihrer späteren Anordnung in einem herzustellenden Behältergebinde entsprechend in die Verpackungsmaschine geleitet werden.The container buffer is preferably designed such that an adjustment of guide elements, such as guide railing, is unnecessary in a format change. This can be done, for example, by an appropriate combination of conveyor belts. Preferably located between the labeling and the at least one packaging machine located second sections of the transport routes are formed in multiple lanes in the form of separate lanes. As a result, the containers can be secured against rotation and transported at a predetermined distance from each other through the individual lanes. Under the streets here are parallel switched, single-lane transport routes to be understood, which are mechanically shielded from each other so that the transported in adjacent lanes containers do not affect each other in their orientation and in their position with respect to the product flow. Such single-lane lanes could for example be easily separated from each other by guide rails. With the help of the separate lanes, the containers can already be passed according to their later arrangement in a container container to be produced in the packaging machine.

Vorzugsweise sind zwischen den ersten und zweiten Abschnitten der Transportstrecken Weichen vorgesehen, mit denen sich die Behälter gruppenweise auf die separaten Gassen verteilen lassen, wobei sich die Behälter ein und derselben Gruppe, insbesondere unter einem Abstand zueinander in die jeweils zugeordnete Gasse einleiten lassen. Die Behälter können entsprechend ihrer Anordnung in einem herzustellenden Behältergebinde gruppenweise auf die einzelnen Gassen verteilt werden. Dadurch, dass die Behälter unter einem Abstand zueinander entlang der Gassen transportiert werden, wird ein Beibehalten einer vorgegebenen Orientierung von Formbehältern bezüglich des Produktstroms während des Transports insbesondere um Kurven erleichtert.Preferably, points are provided between the first and second sections of the transport routes, with which the containers can be distributed in groups on the separate lanes, wherein the container one and the same group, in particular at a distance to each other in the respective associated lane can initiate. The containers can be distributed in groups according to their arrangement in a container container to be produced on the individual lanes. Characterized in that the containers are transported at a distance from each other along the streets, maintaining a predetermined orientation of mold containers with respect to the product flow during transport, in particular around curves is facilitated.

Vorzugsweise gehen die Gassen der zweiten Abschnitte in entsprechende Packspuren der wenigstens einen Verpackungsmaschine über, wobei sich die Behälter ein und derselben Gruppe insbesondere ohne Abstand zueinander in die Packspuren einleiten lassen. Dadurch wird ein schonender Transport der Behälter in einer für die Gebindeherstellung geeigneten Stellung in die Packmaschine erleichtert. Insbesondere werden die Behälter ohne Abstand zueinander in einer dem herzustellenden Gebinde entsprechenden Gruppierung in die Packmaschine eingeleitet. Dadurch lassen sich auch Formbehälter besonders zuverlässig in einer vorgegebenen Drehlage in die Packmaschine einleiten.The lanes of the second sections preferably merge into corresponding packing lanes of the at least one packaging machine, wherein the containers of one and the same group can be introduced into the packing lanes, in particular without spacing from one another. This will be a gentle transport of the container in a suitable for the container production position in the packing machine easier. In particular, the containers are introduced into the packing machine without spacing relative to one another in a grouping corresponding to the pack to be produced. As a result, mold containers can also be introduced into the packing machine in a predetermined rotational position in a particularly reliable manner.

Der Behältertransport entlang separater Gassen ist insbesondere bei Formbehältern von Vorteil, da sich diese in den separaten Gassen nicht gegenseitig verkeilen können.The container transport along separate lanes is particularly advantageous in the case of mold containers, since they can not wed each other in the separate lanes.

Vorzugsweise sind den Transportstrecken separate Verpackungsmaschinen zugeordnet. Dadurch müssen die Behälter vor der Packmaschine nicht auf eine gemeinsame Förderstrecke zusammengeführt werden. Dies ist insbesondere bei Formbehältern von Vorteil, um ein Verkeilen der Behälter beim Zusammenführen zu vermeiden. Außerdem lässt sich der Wirkungsgrad der Abfülleinlage insgesamt gegenüber einer für wenigstens zwei Transportstrecken gemeinsamen Verpackungsmaschine erhöhen.Preferably, the transport routes are assigned separate packaging machines. As a result, the containers in front of the packaging machine do not have to be brought together on a common conveyor line. This is particularly advantageous in the case of mold containers in order to avoid wedging of the containers when merging. In addition, the efficiency of the filling insert can be increased overall in relation to a packaging machine common to at least two transport sections.

Es können auch unterschiedliche Verpackungsmaschinen vorgesehen sein, beispielsweise eine Verpackungsmaschine für Kartonage und eine Verpackungsmaschine für Folie. Diese können jeweils einer bestimmten Transportstrecke zugeordnet sein oder auch abwechselnd einer oder mehrerer Transportstrecken zugeordnet werden.It can also be provided different packaging machines, such as a packaging machine for cardboard and a packaging machine for film. These can each be assigned to a specific transport route or alternatively assigned to one or more transport routes.

Eine besonders günstige Ausführungsform der Abfüllanlage umfasst ferner eine ausgangsseitige Sortiereinrichtung, insbesondere eine Weiche, zum Verteilen der in Form von Behältergebinden verpackten Behälter auf mehrere Sortiergassen, insbesondere für ein nachfolgendes Kommissionieren der Behältergebinde. Das Zusammenführen getrennter Produktströme und das Sortieren für eine nachfolgende Kommissionierung lässt sich nach dem Zusammenfassen der befüllten Behälter in Gebinden unabhängig davon, ob es sich um Standardbehälter oder Formbehälter handelt, zuverlässiger durchführen als dies bei dem Zusammenführen und Sortieren einzelner Behälter, insbesondere bei Formbehältern, der Fall wäre. Es können hierzu aus dem Stand der Technik bekannte Vorrichtungen zum Zusammenführen und/oder Sortieren verwendet werden. Es ist hierbei entscheidend, dass das Zusammenführen und/oder Sortieren stromabwärts der Verpackungsmaschinen erfolgt.A particularly favorable embodiment of the bottling plant further comprises an output-side sorting device, in particular a switch, for distributing the containers packed in the form of container bundles to a plurality of sorting alleys, in particular for a subsequent picking of the container bundles. The merging of separate product streams and the sorting for a subsequent order picking can be done after summarizing the filled containers in containers, regardless of whether they are standard container or mold container, more reliable than in the merging and sorting of individual containers, especially in mold containers, the Case would be. It can be used for this purpose from the prior art devices for merging and / or sorting. It is crucial that the merging and / or sorting takes place downstream of the packaging machines.

Eine weitere besonders günstige Ausführungsform der Abfüllanlage umfasst ferner eine Blasmaschine, deren Maschinenleistung insbesondere im laufenden Betrieb variabel einstellbar ist. Dadurch können besonders kompakte und wirtschaftliche Abfüllanlagen realisiert werden. Insbesondere bei bezüglich der Maschinenleistung einstellbaren Blasmaschinen ergibt sich ferner der Vorteil, dass bei einer Reduzierung der Maschinenleistung stromabwärts der Füllmaschine auch eine Reduzierung der Maschinenleistung stromaufwärts der Füllmaschine realisierbar ist, um ein vollständiges Herunterfahren des Abfüllanlage bei partiellen Produktionsunterbrechungen und/oder bei Produktumstellungen zu vermeiden. Anders gesagt lässt sich mit einer einstellbaren Blasmaschine eine gegebenenfalls benötigte reduzierte Maschinenleistung ohne ein Volllaufen der Behälterpuffer realisieren. Ebenso wäre es denkbar, die Maschinenleistung stromaufwärts der Füllmaschine vorgesehener Blasmaschinen erst nach einem vollständigen Befüllen wenigstens eines stromabwärts der Verteileinrichtung vorgesehenen Behälterpuffers zu reduzieren. Dies ermöglicht einen besonders wirtschaftlichen und flexiblen Betrieb der Abfüllanlage.Another particularly advantageous embodiment of the bottling plant further comprises a blow molding machine whose machine performance is variably adjustable, in particular during operation. As a result, particularly compact and economical filling plants can be realized. In particular, with respect to the machine performance adjustable blowing machines also results in the advantage that with a reduction in engine power downstream the filling machine can also be realized a reduction of the machine power upstream of the filling machine in order to avoid a complete shutdown of the filling plant during partial production stoppages and / or during product changes. In other words, an optionally required reduced machine power can be achieved with an adjustable blow molding machine without a full run of the container buffers. Likewise, it would be conceivable to reduce the engine power upstream of the filling machine provided blow molding machines only after a complete filling of at least one provided downstream of the distribution device container buffer. This allows a particularly economical and flexible operation of the filling plant.

Ebenso können wenigstens zwei Blasmaschinen in der Abfüllanlage vorgesehen sein. Besonders vorteilhaft ist beispielsweise eine Kombination einer ersten Blasmaschine für Standardbehälter und einer zweiten Blasmaschine für Formbehälter. Ebenso sind Abfüllanlagen denkbar, bei denen eine erste Blasmaschine, beispielsweise für Standardbehälter, mittels einer eingangsseitigen Transportstrecke, wie beispielsweise einer Lufttransportstrecke, mit der Füllmaschine verbunden ist, und bei der eine zweite Blasmaschine, beispielsweise zum Herstellen von Formbehältern, mit der Füllmaschine als gemeinsamer Maschinenblock ausgebildet ist. Die Füllmaschine kann dann eingangsseitig eine herkömmliche Weiche umfassen, um gezielt die von der ersten Blasmaschine oder der zweiten Blasmaschine hergestellten Behälter weiterzuverarbeiten.Likewise, at least two blow molding machines may be provided in the bottling plant. For example, a combination of a first blowing machine for standard containers and a second blowing machine for forming containers is particularly advantageous. Likewise, bottling plants are conceivable in which a first blow molding machine, for example for standard containers, is connected to the filling machine by means of an input-side transport route, such as an air transport route, and a second blow molding machine, for example for producing molded containers, with the filling machine as a common machine block is trained. The filling machine can then comprise a conventional switch on the input side in order to specifically process the containers produced by the first blowing machine or the second blowing machine.

Die gestellte Aufgabe wird ebenso mit einem Verfahren nach Anspruch 12 zum Betreiben der erfindungsgemäßen Abfüllanlage gelöst. Demnach wird mit Hilfe der Verteileinrichtung der Strom aus befüllten Behältern bei ordnungsgemäßem Anlagenbetrieb in Gruppen auf die Transportstrecken verteilt, insbesondere zu gleichen Anteilen. Beispielsweise werden die Behälter zu diesem Zweck in Gruppen von je 2 bis 12 Behältern abwechselnd auf die Transportstrecken verteilt. Große Gruppen zu je 6 bis 12 Behältern, beispielsweise zu je 8 bis 10 Behältern, sind besonders praktikabel und vorteilhaft, da sie die Anzahl der benötigten Schaltvorgänge der Verteileinrichtung reduzieren.The stated object is also achieved by a method according to claim 12 for operating the filling plant according to the invention. Accordingly, with the help of the distribution device, the stream of filled containers is distributed in proper plant operation in groups on the transport routes, in particular in equal proportions. For example, the containers are distributed for this purpose in groups of 2 to 12 containers alternately on the transport routes. Large groups of 6 to 12 containers, for example of 8 to 10 containers each, are particularly practicable and advantageous because they reduce the number of switching operations required by the distributor.

Ein Verteilen zu gleichen Anteilen auf die Transportstrecken ermöglicht insbesondere bei ordnungsgemäßem Betrieb der Abfüllanlage eine optimierte Maschinenleistung der Anlage. Besonders vorteilhaft ist ein Verteilen der Behälter auf die Transportstrecke derart, dass die Anzahl der beschickten Gassen einer Breite der herzustellenden Gebinde entspricht. Darunter ist zu verstehen, dass die Behälter beispielsweise für Gebinde aus 3 x 4 Behältern auf drei Gassen oder vier Gassen verteilt werden. Die Gruppenstärke muss dabei nicht zwangsläufig der jeweiligen Länge der herzustellenden Gebinde entsprechen. Beispielsweise könnten die Gruppen aus je 10 Behältern bestehen und die Gebinde eine Länge von 4 Behältern aufweisen.Distributing in equal proportions on the transport routes, in particular with proper operation of the bottling plant, enables optimized machine performance of the plant. Particularly advantageous is a distribution of the container on the transport path such that the number of loaded lanes corresponds to a width of the container to be produced. By this is meant that the containers are distributed, for example, for packages of 3 x 4 containers on three streets or four lanes. The group strength does not necessarily have to correspond to the respective length of the container to be produced. For example The groups could consist of 10 containers each and the containers have a length of 4 containers.

Vorzugsweise wird die Spurbreite der Transportstrecken zum verdrehsicheren Behältertransport an wenigstens einen nicht runden Behälterquerschnitt angepasst. Darunter ist zu verstehen, dass sich Formbehälter beispielsweise stets an gleichbleibenden umfänglichen Teilabschnitten ihres Querschnitts seitlich führen lassen. Dadurch lässt sich ein Querstellen, Verkeilen und/oder Blockieren der Behälter vermeiden und somit ein stellungsgerechter Transport bis hin zur Verpackungsmaschine realisieren. Darunter ist zu verstehen, dass insbesondere Formbehälter in einer bestimmten Drehlage bezüglich des Produktstroms zur Verpackungsmaschine gefördert werden können, die vorzugsweise bereits ihrer Orientierung im herzustellenden Behältergebinde entspricht.Preferably, the track width of the transport paths for non-rotatable container transport is adapted to at least one non-round container cross-section. By this is meant that, for example, mold containers can always be guided laterally at constant circumferential sections of their cross section. As a result, it is possible to avoid cross-over, wedging and / or jamming of the containers and thus to realize a position-appropriate transport up to the packaging machine. This is to be understood that in particular mold containers can be conveyed in a certain rotational position with respect to the product flow to the packaging machine, which preferably already corresponds to their orientation in the container container to be produced.

Vorzugsweise wird die Abfüllanlage bei einer Produktionsunterbrechung entlang einer der Transportstrecken weitergefahren, insbesondere bei unverminderter Füllleistung, bis der Behälterpuffer in der von der Unterbrechung betroffenen Transportstrecke befüllt ist. Dadurch wird ein stromaufwärts der Verteileinrichtung ordnungsgemäßer Betrieb bei unverminderter Maschinenleistung zumindest bei vergleichsweise kurzen Produktionsunterbrechungen oder Produktionsumstellungen ermöglicht. Insbesondere können Phasen des Herunterfahrens und Anfahrens stromaufwärts vermieden oder zumindest verkürzt werden. Die Ausfallsicherheit der Abfüllanlage insgesamt kann dadurch erhöht werden. Ebenso steigt die Maschinenleistung insgesamt und somit de Wirtschaftlichkeit der Abfüllanlage.Preferably, the filling system is continued in a production interruption along one of the transport routes, in particular at undiminished filling capacity until the container buffer is filled in the affected by the interruption transport path. As a result, proper operation upstream of the distributor is made possible with undiminished machine performance, at least for comparatively short production stoppages or production changes. In particular, phases of shutdown and startup upstream can be avoided or at least shortened. The reliability of the bottling plant as a whole can be increased thereby. The machine performance as a whole and thus the efficiency of the bottling plant also increase.

Vorzugsweise werden die Behälter vor der Verpackungsmaschine auf mehrere einspurige Gassen drucklos verteilt, und die Anzahl der derart beschickten Gassen entspricht einer in der Verpackungsmaschine herzustellenden Gebindegröße. Durch den drucklosen Transport lassen sich unterschiedliche Behältertypen, insbesondere sowohl Standardbehälter als auch Formbehälter, gleichermaßen von der Füllmaschine bis zur Verpackungsmaschine transportieren. Das Verteilen in Abhängigkeit einer Gebindegröße ist besonders wirtschaftlich, da zusätzliche Sortier- und Ausrichteinheiten für die unterschiedlichen Behälter entbehrlich sind.Preferably, the containers are distributed without pressure in front of the packaging machine on a plurality of single-lane streets, and the number of lanes loaded in this way corresponds to a container size to be produced in the packaging machine. Due to the non-pressure transport, different types of containers, in particular both standard containers and mold containers, can be equally transported from the filling machine to the packaging machine. The distribution depending on a container size is particularly economical, since additional sorting and alignment units are dispensable for the different containers.

Eine bevorzugte Ausführungsform der erfindungsgemäßen Abfüllanlage ist in der Zeichnung dargestellt.A preferred embodiment of the filling system according to the invention is shown in the drawing.

Die einzige Figur zeigt eine bevorzugte Ausführungsform der Abfüllanlage 1 in einer schematischen Draufsicht. Demnach umfasst die Abfüllanlage 1 zum Befüllen von Behältern 2, 3 mit einem flüssigen Produkt, wie beispielsweise einem Getränk oder dergleichen, eine Füllmaschine 5 zum Befüllen und Verschließen der Behälter 2, 3 und eine stromabwärts der Füllmaschine 5 vorgesehene Verteileinrichtung 6 zum Verteilen der Behälter 2, 3 auf zwei getrennt steuerbare Transportstrecken 7, 8, in denen jeweils wenigstens ein Behälterpuffer 9, 10 vorgesehen ist. Den Behälterpuffern 9, 10 nachgeschaltet sind Etikettiermaschinen 11, 12 sowie Verpackungsmaschinen 13, 14 zum Herstellen von Behältergebinden 15. Diese werden einer Sammel- und Verteileinrichtung 16 zugeführt, so dass die Behältergebinde 15 auf stromabwärts der Sammel- und Verteileinrichtung 16 vorgesehene Sortierspuren 17 verteilt werden und einer Kommissioniereinrichtung 18 zugeführt werden können.The single figure shows a preferred embodiment of the filling plant 1 in a schematic plan view. Accordingly, the filling installation 1 for filling containers 2, 3 with a liquid product, such as a beverage or the like, comprises a filling machine 5 for filling and closing the containers 2, 3 and one downstream the filling machine 5 provided distribution device 6 for distributing the container 2, 3 on two separately controllable transport paths 7, 8, in each of which at least one container buffer 9, 10 is provided. The container buffers 9, 10 downstream labeling machines 11, 12 and packaging machines 13, 14 for producing container containers 15. These are fed to a collecting and distributing device 16, so that the container bundles 15 are provided on the downstream of the collecting and distributing device 16 provided sorting tracks 17 and a picking 18 can be supplied.

Die Behälter 2, 3 sind beispielsweise Kunststoffbehälter unterschiedlicher Typen. Angedeutet sind schematisch Behälter 2 mit rundem Querschnitt, sogenannte Standardbehälter, und Behälter 3 mit polygonalem Querschnitt, sogenannte Formbehälter. Ein Vorteil der Abfüllanlage 1 ist deren Eignung für unterschiedliche Behälterquerschnitte. Die beschriebenen Behältertypen sind daher lediglich beispielhaft.The containers 2, 3 are, for example, plastic containers of different types. The figures schematically indicate containers 2 with a round cross section, so-called standard containers, and containers 3 with a polygonal cross section, so-called mold containers. An advantage of the filling plant 1 is its suitability for different container cross sections. The container types described are therefore merely exemplary.

Die Transportstrecken 7, 8 umfassen jeweils erste eingangsseitige Abschnitte 7a, 8a, die einspurig und für den drucklosen Transport der Behälter 2, 3 ausgebildet sind. Ferner umfassen die Transportstrecken 7, 8 ausgangsseitige zweite Abschnitte 7b, 8b, die jeweils mehrspurig für den drucklosen Transport der Behälter 2, 3 ausgebildet sind. Für die Verteilung der Behälter 2, 3 von dem einspurigen ersten Abschnitt 7a, 8a auf die einzelnen Spuren des zweiten Abschnitts 7b, 8b, die beispielsweise in Form separater Gassen 7b1 bis 7b3, 8b1 bis 8b3 ausgebildet sind, sind Weichen 7c, 8c oder entsprechende Verteileinrichtungen vorgesehen. In der Figur sind der Übersichtlichkeit halber die den Gassen zugeordneten Transportwege dargestellt nicht die seitlichen Begrenzungen der Gassen, wie beispielsweise Geländer.The transport paths 7, 8 each comprise first input-side sections 7a, 8a, which are formed in one track and for the unpressurized transport of the containers 2, 3. Furthermore, the transport sections 7, 8 comprise second sections 7b, 8b on the output side, which are each formed in multiple tracks for the pressureless transport of the containers 2, 3. For the distribution of the containers 2, 3 of the single-track first portion 7a, 8a on the individual tracks of the second portion 7b, 8b, which are formed for example in the form of separate lanes 7b1 to 7b3, 8b1 to 8b3, turnouts 7c, 8c or equivalent Distributed devices provided. In the figure, for the sake of clarity, the transport routes associated with the lanes are not shown as the lateral boundaries of the lanes, such as railings.

Wie die Figur ferner schematisch andeutet, werden die Behälter 2, 3 von der Verteileinrichtung 6 gruppenweise auf die Transportstrecken 7, 8 verteilt. Im gezeigten Beispiel werden die Behälter 2 in Gruppen 2' zu je 4 Behältern abwechselnd auf die beiden Transportstrecken 7, 8 verteilt. Dies entspricht einer bevorzugten Betriebsweise bei ordnungsgemäßer Funktion der Abfüllanlage 1. Das heißt, die Behälter 2, 3 werden vorzugsweise zu gleichen Anteilen von der Verteileinrichtung 6 auf die beiden Transportstrecken 7, 8 verteilt. Somit werden die beiden den Transportstrecken 7, 8 zugeordneten Etikettiermaschinen 11, 12 in gleicher Weise ausgelastet.As the figure also indicates schematically, the containers 2, 3 are distributed by the distribution device 6 in groups on the transport paths 7, 8. In the example shown, the containers 2 are alternately distributed in groups 2 'to 4 containers on the two transport paths 7, 8. This corresponds to a preferred mode of operation with proper function of the filling system 1. That is, the containers 2, 3 are preferably distributed in equal proportions by the distributor 6 on the two transport paths 7, 8. Thus, the two the transport sections 7, 8 associated labeling 11, 12 are utilized in the same way.

Die Behälter 2, 3 durchlaufen zwischen der Verteileinrichtung 6 und den Etikettiermaschinen 11, 12 jeweils den zwischengeschalteten Behälterpuffer 9, 10. Dieser kann je nach Betriebszustand der Abfüllanlage in bekannter Weise, beispielsweise wie in der DE 20 2004 012 848 U1 beschrieben ist, auf unterschiedliche Pufferkapazitäten eingestellt werden. Dies ist in der Figur mit verstellbaren Behälterführungen 9a, 10a angedeutet. Es lassen sich damit Auslastungsschwankungen in den beiden Transportstrecken 7, 8 kompensieren, ebenso zumindest zeitweise eine Kapazitätsreduzierung oder eine Produktionsunterbrechung in einer der beiden Transportstrecken 7, 8.The containers 2, 3 pass between the distribution device 6 and the labeling machines 11, 12 respectively the intermediate container buffers 9, 10. This can depending on the operating condition of the filling in a known manner, for example as in the DE 20 2004 012 848 U1 is described, be set to different buffer capacities. This is in the figure with adjustable container guides 9a, 10a indicated. It can thus compensate for load fluctuations in the two transport routes 7, 8, as well as at least temporarily a reduction in capacity or a production interruption in one of the two transport routes 7, 8.

Fällt zum Beispiel die eine Etikettiermaschine 11 aufgrund einer Betriebsstörung oder eines Etikettenwechsels oder dergleichen zeitweise aus, so kann die Verteileinrichtung 6 den einlaufenden Behälterstrom zunächst weiter in Richtung beider Behälterpuffer 9, 10 verteilen, zumindest so lange, bis der Behälterpuffer 9 vor der nicht betriebsbereiten Etikettiermaschine 11 vollständig gefüllt ist. Währenddessen wird die andere Etikettiermaschine 12 weiterhin ordnungsgemäß mit Behältern 2, 3 beschickt.If, for example, the one labeling machine 11 temporarily fails due to a malfunction or a label change or the like, the distributor device 6 can initially distribute the incoming container stream further in the direction of the two container buffers 9, 10, at least until the container buffer 9 in front of the non-operational labeling machine 11 is completely filled. Meanwhile, the other labeling machine 12 continues to be properly loaded with containers 2, 3.

Bei geeigneter Förderkapazität der einzelnen Transportstrecken 7, 8 könnten nach einer Befüllung des Behälterpuffers 9 alle Behälter 2, 3 in Richtung der funktionstüchtigen Etikettiermaschine 12 geleitet werden. Bei unvermindertem Behälterzustrom aus der Füllmaschine 5 in Richtung der Verteileinrichtung 6 laufen in den Behälterpuffer 10 dann pro Zeiteinheit doppelt so viele Behälter 2, 3 ein wie bei normalem, ordnungsgemäßem Betrieb. Da der Abstrom aus dem Behälterpuffer 10 durch die Maschinenleistung der Etikettiermaschine 12 begrenzt ist und normalerweise unterhalb der Maschinenleistung der Füllmaschine 5 liegt, füllt sich dann auch der Behälterpuffer 10 auf Grund des partiellen Stillstands in der Transportstrecke 7 kontinuierlich. Die Maschinenleistung stromaufwärts der Verteileinrichtung 6 kann zumindest bis zum vollständigen Befüllen eines der Behälterpuffer 9, 10 unverändert beibehalten werden, gegebenenfalls bis beide Behälterpuffer 9, 10 gefüllt sind.With a suitable conveying capacity of the individual transport sections 7, 8, all containers 2, 3 could be directed in the direction of the functional labeling machine 12 after filling the container buffer 9. With an unimpeded flow of containers from the filling machine 5 in the direction of the distributor 6, then twice as many containers 2, 3 enter into the container buffer 10 as they do during normal, proper operation. Since the outflow from the container buffer 10 is limited by the machine power of the labeling machine 12 and is normally below the machine output of the filling machine 5, then the container buffer 10 fills continuously due to the partial standstill in the transport path 7. The machine power upstream of the distributor 6 can be maintained unchanged at least until the filling of one of the container buffers 9, 10, if necessary, until both container buffers 9, 10 are filled.

Somit ergibt sich je nach Kapazität der Behälterpuffer 9, 10 eine Pufferzeit, innerhalb der der Ausfall einer Produktionseinheit innerhalb einer der Transportstrecken 7, 8 derart kompensiert werden kann, dass eine Reduzierung der Maschinenleistung oder eine Produktionsunterbrechung stromaufwärts der Verteileinrichtung 6 verhindert werden kann. Dies ist insbesondere deshalb von Vorteil, weil ein Herunterfahren und anschließendes Hochfahren dieser Anlagenteile, beispielsweise von Blasmaschinen, innerhalb der Pufferzeit entbehrlich wird. Gerade dadurch lassen sich vergleichsweise kostspielige Ausfallzeiten der Abfüllanlage 1 vermeiden.Thus, depending on the capacity of the container buffers 9, 10 results in a buffer time within which the failure of a production unit within one of the transport lines 7, 8 can be compensated such that a reduction in machine power or a production interruption upstream of the distributor 6 can be prevented. This is particularly advantageous because a shutdown and subsequent startup of these parts of the system, for example, blow molding machines, is dispensable within the buffer time. This makes it possible to avoid comparatively expensive downtimes of the filling installation 1.

Wie in der Figur angedeutet ist, umfasst die Abfüllanlage vorzugsweise wenigstens eine Blasmaschine 19, 20. Im gezeigten Beispiel sind getrennte Blasmaschinen 19, 20 zum Herstellen unterschiedlicher Behälter 2, 3 vorgesehen. Beispielsweise wird mit einer ersten Blasmaschine 19 ein Behälter 2 mit Standardquerschnitt, insbesondere mit einem runden Behälterquerschnitt, hergestellt. Vorzugsweise wird mit einer zweiten Blasmaschine 20 ein Behälter 3 mit einem nicht runden Querschnitt hergestellt, beispielsweise mit einem polygonalen, insbesondere rechteckigen, oder mit einem ovalen Querschnitt.As indicated in the figure, the filling installation preferably comprises at least one blow molding machine 19, 20. In the example shown, separate blow molding machines 19, 20 are provided for producing different containers 2, 3. For example, with a first blow molding machine 19 a container 2 with standard cross-section, in particular with a round container cross-section, produced. Preferably, with a second blow molding machine 20, a container 3 having a non-round cross section is produced, for example with a polygonal, in particular rectangular, or with an oval cross section.

Wie die Figur ferner verdeutlicht, kann wenigstens eine der Blasmaschinen 19, 20 mit der Füllmaschine 5 als gemeinsamer Maschinenblock ausgebildet sein. Ebenso kann wenigstens eine der Blasmaschinen 19, 20 über eine eingangsseitige Transportstrecke 21, wie beispielsweise eine Lufttransportstrecke bekannter Bauart, mit der Füllmaschine 5 verbunden sein. Die gezeigte Variante ist hierbei lediglich beispielhaft. Prinzipiell lassen sich an die Füllmaschine 5 beliebige Blasmaschinen 19, 20 ankoppeln.As the figure further illustrates, at least one of the blowing machines 19, 20 may be formed with the filling machine 5 as a common machine block. Likewise, at least one of the blowing machines 19, 20 can be connected to the filling machine 5 via an input-side transport path 21, such as an air-transport route of known design. The variant shown here is merely an example. In principle, any desired blow molding machines 19, 20 can be coupled to the filling machine 5.

Ebenso wäre es denkbar, wenigstens einen Behältertyp außerhalb der Abfüllanlage 1 herzustellen. Lediglich schematisch ist in der Figur eine eingansseitige Weiche 5a der Füllmaschine 5 dargestellt, mit der unterschiedliche einlaufende Behälterströme der weiteren Verarbeitung zugeführt werden können.It would also be conceivable to produce at least one type of container outside the bottling plant 1. Only schematically, in the figure, an input-side switch 5a of the filling machine 5 is shown, with the different incoming container streams of further processing can be supplied.

Die beschriebene Abfüllanlage 1 eignet sich insbesondere zum Verarbeiten unterschiedlicher Behältertypen, insbesondere zum Verarbeiten von Behältern 2 mit rundem Querschnitt und von Behältern 3 mit nicht rundem Querschnitt. Geeignete Füllmaschinen 5 sind aus dem Stand der Technik bekannt und müssen daher hier nicht weiter beschrieben werden. Entscheidend ist hierbei, dass die Transportstrecken 7, 8 und die zugeordneten Behälterpuffer 9, 10 für den drucklosen Transport der Behälter 2, 3 ausgebildet sind. Nur dadurch wird ein störungsfreier Betrieb beim Abfüllen von Behältern 3 mit nicht rundem Querschnitt gewährleistet. Der drucklose Transport ermöglicht insbesondere ein störungsfreies Puffern unterschiedlicher Behältertypen in den Behälterpuffern 9, 10. Diese sind einspurig und arbeiten ebenfalls ohne Staudruck, wie beispielsweise in der DE 20 2004 012 848 U1 beschrieben ist.The bottling plant 1 described is particularly suitable for processing different types of containers, in particular for processing containers 2 with a round cross section and containers 3 with non-round cross section. Suitable filling machines 5 are known from the prior art and therefore need not be further described here. It is crucial here that the transport paths 7, 8 and the associated container buffers 9, 10 are designed for the non-pressurized transport of the containers 2, 3. Only by a trouble-free operation when filling containers 3 is guaranteed with non-round cross-section. The pressureless transport allows in particular a trouble-free buffering of different types of containers in the container buffers 9, 10. These are single-track and also work without back pressure, such as in the DE 20 2004 012 848 U1 is described.

Für die Steuerung der Abfüllanlage 1 ist vorzugsweise eine zentrale Steuereinheit 22 vorgesehen, die insbesondere mit der Verteileinrichtung 6, den Behälterpuffern 9, 10, den Etikettiermaschinen 11, 12 und Produktionseinheiten stromaufwärts der Verteileinrichtung 6, wie beispielsweise der Füllmaschine 5 und den Blasmaschinen 19, 20 kommuniziert (Kommunikationswege sind in der Figur der Übersichtlichkeit halber nicht dargestellt). Entscheidend hierbei ist, dass die Verteileinrichtung 6 mit Hilfe der Steuereinheit 22 bei einer stromabwärts der Verteileinrichtung 6 festgestellten partiellen Produktionsunterbrechung den Zustrom von Behältern 2, 3 in die von der Produktionsunterbrechung betroffene Transportstrecke 7, 8 gezielt unterbinden kann und den Behälterstrom gezielt in einen Behälterpuffer 9, 10 leiten kann, hinter dem der Produktionsbetrieb weiterhin ordnungsgemäß erfolgt.For the control of the filling plant 1, a central control unit 22 is preferably provided, in particular with the distributor 6, the container buffers 9, 10, the labeling machines 11, 12 and production units upstream of the distributor 6, such as the filling machine 5 and the blowing machines 19, 20th communicates (communication paths are not shown in the figure for clarity). Decisive here is that the distribution device 6 with the help of the control unit 22 at a downstream of the distribution device 6 detected partial production interruption can selectively prevent the influx of containers 2, 3 in the affected by the production interruption transport section 7, 8 and the container stream targeted in a container buffer. 9 10, behind which the production operation continues to operate properly.

Die Kommunikation zwischen der Steuereinheit 22 und den Behälterpuffern 9, 10 ermöglicht es zudem, den Befüllungsgrad oder die Restkapazität der Behälterpuffer 9, 10 festzustellen, um den Behälterzustrom in den jeweiligen Behälterpuffer 9, 10 bei dessen vollständiger Befüllung zu unterbrechen. In diesem Fall ermöglicht die Kommunikation mit dem stromaufwärts der Verteileinrichtung 6 vorgesehen Produktionseinheiten, dass diese bei Bedarf heruntergefahren werden können.The communication between the control unit 22 and the container buffers 9, 10 also makes it possible to determine the degree of filling or the residual capacity of the container buffers 9, 10 in order to interrupt the container flow into the respective container buffers 9, 10 when it is completely filled. In this case, the communication with the production units provided upstream of the distribution device 6 enables them to be shut down if necessary.

Die Etikettiermaschinen 11, 12 sind beispielsweise Sleeve-Aggregate, die in der Regel eine deutlich geringere Maschinenleistung aufweisen als die Produktionseinheiten stromaufwärts der Verteileinrichtung 6. Somit ermöglicht die Aufteilung des Behälterstroms an der Verteileinrichtung 6 zum Einen eine Erhöhung der Maschinenleistung der Abfüllanlage 1 bei ordnungsgemäßem Betrieb, zum anderen eine Reduzierung von Ausfallzeiten der Abfüllanlage 1 insgesamt. Zusätzlich ermöglichen die Behälterpuffer 9, 10 in doppelter Ausführung eine ausreichende Pufferkapazität auch bei Behältern 3 mit nicht rundem Querschnitt.The labeling machines 11, 12 are, for example, sleeve units, which generally have a significantly lower machine output than the production units upstream of the distributor 6. Thus, the division of the container flow at the distributor 6 on the one hand enables an increase in the machine output of the filling system 1 during proper operation on the other hand, a reduction of downtime of the bottling plant 1 overall. In addition, the container buffers 9, 10 in duplicate allow sufficient buffer capacity even in containers 3 with non-round cross-section.

Der Vollständigkeit halber sind in der Figur zusätzliche Produktionseinheiten 23, 24 im Bereich der ersten Abschnitte 7a, 8a der Transportstrecken 7, 8 angedeutet. Dies könnten beispielsweise Schrumpftunnel oder dergleichen sein.For the sake of completeness, additional production units 23, 24 in the region of the first sections 7a, 8a of the transport paths 7, 8 are indicated in the figure. These could be, for example, shrink tunnels or the like.

Im zweiten Abschnitt 7b, 8b der Transportstrecken 7, 8 werden die Behälter 2, 3 gruppenweise auf die Gassen 7b1 bis 7b3 und 8b1 bis 8b3 verteilt und so weiter transportiert, dass sich die Behälter 2, 3 benachbarter Gassen gegenseitig nicht stören. Darunter ist zu verstehen, dass die Behälter 2, 3 eine vorgegebene Drehlage und einen vorgegebenen Abstand zueinander beibehalten. Hierbei ist es gegebenenfalls von Vorteil, die Behälter 2, 3 nach dem Verteilen auf die einzelnen Gassen in einem geringen Abstand zueinander zu transportieren, um beispielsweise ein gegenseitiges Beeinflussen hintereinander stehenden Behälter 2, 3 beim Transport um Kurven oder dergleichen zu vermeiden.In the second section 7b, 8b of the transport paths 7, 8, the containers 2, 3 are distributed in groups on the lanes 7b1 to 7b3 and 8b1 to 8b3 and transported so that the container 2, 3 adjacent lanes do not interfere with each other. By this is meant that the containers 2, 3 maintain a predetermined rotational position and a predetermined distance from each other. In this case, it may be advantageous to transport the containers 2, 3 after distributing them to the individual lanes at a small distance from one another, in order, for example, to prevent mutual interference between containers 2, 3 standing one behind the other during transport around curves or the like.

Allerdings werden die Behälter 2, 3 dann unmittelbar vor dem Einlaufen in die Verpackungsmaschine 13, 14 auf Kontakt miteinander gebracht, so dass sie in einer Stellung entsprechend dem herzustellenden Behältergebinde 15 einlaufen. Dadurch lässt sich das Verpacken der Behälter 2, 3 vereinfachen. Hierbei ist die gezeigte Anzahl der Gassen 7b1 bis 7b3 und 8b1 bis 8b3 lediglich beispielhaft. Vorzugsweise entspricht die Anzahl der jeweils nebeneinander liegenden Gassen einer maximalen Gebindebreite, d. h. der Anzahl der Behälter 2, 3, die nebeneinander in einem der Gebinde 15 zusammengefasst werden sollen. Je nach der tatsächlich herzustellenden Gebindegröße werden dann nur die jeweils benötigten Gassen 7b1 bis 7b3, 8b1 bis 8b3 mit Behältern 2, 3 beschickt.However, the containers 2, 3 are then brought into contact with each other immediately before entering the packaging machine 13, 14, so that they run in a position corresponding to the container package 15 to be produced. As a result, the packaging of the container 2, 3 can be simplified. Here, the shown number of the lanes 7b1 to 7b3 and 8b1 to 8b3 is merely exemplary. Preferably, the number of each adjacent lanes corresponds to a maximum package width, ie the number of containers 2, 3, which are to be summarized next to each other in one of the container 15. Depending on the actual size of the container to be produced, only the respectively required lanes 7b1 to 7b3, 8b1 to 8b3 are then charged with containers 2, 3.

Das gassenweise Zuführen der Behälter 2, 3 ist insbesondere bei Behältern 3 mit nicht rundem Querschnitt von Vorteil. Es erübrigt sich dann ein Zusammenfassen dieser Behälter von unterschiedlichen Transportstrecken 7, 8 kommend vor einer gemeinsamen Verpackungsmaschine. Ein derartiges Zusammenführen von Behältern 3 ist insbesondere bei nicht runden Querschnitten aufgrund eines möglichen Querstellens und/oder Verkeilens der Behälter 3 problematisch. Anders gesagt, ist insbesondere eine Variante von Vorteil, bei der die Anzahl der Verpackungsmaschinen 13, 14 der Anzahl der separaten Transportstrecken 7, 8 entspricht.The gassed feeding of the containers 2, 3 is particularly advantageous in containers 3 with non-round cross-section. It is then unnecessary to combine these containers of different transport routes 7, 8 coming in front of a common packaging machine. Such a merging of containers 3 is particularly problematic in non-round cross-sections due to a possible cross-placement and / or wedging the container 3. In other words, a variant in which the number of packaging machines 13, 14 corresponds to the number of separate transport sections 7, 8 is particularly advantageous.

Um einen flexiblen und zuverlässigen Betrieb der Abfüllanlage 1 zu ermöglichen, sind die Transportstrecken 7, 8 getrennt steuerbar. Das heißt, je nach benötigter Maschinenleistung und/oder bei einem Teilausfall der Produktion in einer der Transportstrecken 7, 8 lässt sich der Behälterstrom mit Hilfe der Verteileinrichtung 6 flexibel und gezielt auf die Transportstrecken 7, 8 hinsichtlich einer optimalen Anlagenauslastung verteilen.In order to enable a flexible and reliable operation of the filling plant 1, the transport routes 7, 8 are separately controllable. That is, depending on the required engine power and / or a partial failure of production in one of the transport sections 7, 8, the container flow with the help of the distribution device 6 can be flexibly and selectively distributed to the transport routes 7, 8 in terms of optimal system utilization.

Wie die Figur ferner andeutet, lässt sich die Abfüllanlage mit wenigstens zwei Transportstrecken 7, 8 besonders vorteilhaft mit als Geradläufer ausgebildeten Produktionseinheiten stromabwärts der Verteileinrichtung 6 realisieren. Prinzipiell sind jedoch auch Rundläufermaschinen an den entsprechenden Stellen denkbar. Dies betrifft auch die Verteileinrichtungen und Weichen der Abfüllanlage 1. Geeignete Verteileinrichtungen vom Geradläufertyp sind beispielsweise Linearverteilweichen oder Dachverteiler. Geeignete Verteileinrichtungen vom Rundläufertyp sind beispielsweise Drehriegelsterne oder Klemmsterne. Die Funktionsweise derartiger Verteileinrichtungen ist bekannt und muss daher an dieser Stelle nicht erläutert werden.As the figure also indicates, the filling installation can be realized with at least two transport sections 7, 8 particularly advantageously with production units designed as a straight-line downstream of the distribution device 6. In principle, however, rotary machines are also conceivable in the appropriate places. This also applies to the distribution devices and points of the filling system 1. Suitable distribution devices of the straight-type are, for example Linearverteilweichen or roof distributor. Suitable distribution devices of the rotary type are, for example, turnstile stars or terminal stars. The operation of such distribution devices is known and therefore need not be explained at this point.

Mit der beschriebenen Abfüllanlage 1 und dem beschriebenen Verfahren zum Betreiben der Abfüllanlage 1, insbesondere den beschriebenen Puffern der Behälter 2, 3 bei einem teilweisen Ausfall der Abfüllanlage stromabwärts der Verteileinrichtung 6 lassen sich besonders flexible und zuverlässige Produktionsbedingungen herstellen.With the described bottling plant 1 and the described method for operating the bottling plant 1, in particular the described buffers of the containers 2, 3 with a partial failure of the bottling plant downstream of the distributor 6, particularly flexible and reliable production conditions can be produced.
