Description

Die Erfindung liegt auf den Gebiet der Produkt-Transporttechnik in einem Hochgeschwindigkeits-Produktherstellungs und -verpackungsprozess und betrifft ein Produkt-Transfer-Verfahren innerhalb des Gesamtherstellungsprozesses, insbesondere die Uebernahme eines Produktausstosses aus einer Maschine und die zeitdilatierte Uebergabe in den nachsten Fertigungsschritt. Das Produkttransferverfahren richtet sich in einer spezifischen Ausführungsform auf den Produktionsausstoss von in Flow-Pack Verfahrensweise verpackten Gütern.The invention lies in the field of product transport technology in a high-speed product manufacturing and packaging process and relates to a product transfer process within the overall manufacturing process, in particular the transfer of a product output from a machine and the time-dilated transfer to the next manufacturing step. In a specific embodiment, the product transfer process is aimed at the production output of goods packaged in flow-pack processes.

Durch die CH-A-559'691 wird gezeigt, wie im Druckereibetrieb der Schuppenstrom von nicht zusammenhängenden Druckprodukten mit Hilfe von Haltebändern über eine horizontale Drehachse auf sogenannte Trommelkörper gewickelt werden. Die Haltebänder werden benötigt, um die losen Druckprodukte zusammenzuhalten. Die aufgewickelten Druckprodukte werden einer Zwischenlagerung zugeführt.CH-A-559'691 shows how the scale flow of non-contiguous printed products is wound on so-called drum bodies with the help of holding straps over a horizontal axis of rotation in the printing shop. The straps are needed to hold the loose print products together. The wound printed products are fed to an intermediate storage.

Durch die US-A-3'747'821. wird beschrieben, wie ein zusammenhängender Wurststrang von der Produktionseinheit über sogenannte Hänger, an denen der Wursttrang schlaufenweise aufgehangt wird, weggefördert und für den Transport in Container abgelegt wird. In diesen Containern kann der Wurststrang zwischengelagert, gelagert oder transportiert werden.By US-A-3,747,821. describes how a coherent strand of sausage is transported away from the production unit via so-called hangers, on which the strand of sausage is hung in loops, and placed in containers for transport. The sausage skein can be stored, stored or transported in these containers.

Durch die EP-A-0'243'753. ist ein Verfahren und eine Vorrichtung zum Verarbeiten von in Schuppenformation anfallenden Druckereierzeugnissen, wie Zeitungen, Zeitschriften und dergleichen bekannt geworden. Darin ist gezeigt, wie eine mit mehreren nebeneinander angeordneten Wickeln beladene Palette mittels einer Kippeinrichtung so gekippt werden kann, dass ein Turm von aufeinander liegenden Wickeln entsteht. Solche Wickeltürme werden einer Zwischenlagerung zugeführt.By EP-A-0'243'753. has become known a method and an apparatus for processing printed products such as newspapers, magazines and the like which are formed in scale formation. It shows how a pallet loaded with several coils arranged side by side can be tilted by means of a tilting device in such a way that a tower of coils lying one on top of the other is created. Such winding towers are supplied to an intermediate storage.

Ein typischer Hochgeschwindigkeits-Herstellungsprozess, bspw. in der Schokoladenherstellung, beginnt bei den Rohmaterialien, die in der Regel aus der Silolagerung über automatische Zuführungen in den Produktionsprozess gelangen. Mahlen, Mischen etc. geschieht vollautomatisch, auch das Mischen und Rühren sind in der Regel automatisierte Produktionsvorgänge. Ein Zwischen-Batch-Betrieb, bspw. das Entleeren der Rührwerke in Behälter mit einen Fassungsvermögen bis Zu 70̸ Tonnen Schokoladenmasse unterbricht wohl den kontinuierlichen Materialfluss, ändert aber am hohen Massenpotential des Herstellungsprozesses gar nichts. Die ersten Engpassprobleme bei hohem Materialdurchsatz zeigen sich am anschliessenden Spritz- oder Giessvorgang, bei dem von der ungeformten Masse eine stückige, also in Portionen aufgeteilten Form entstehen soll.A typical high-speed manufacturing process, for example in chocolate production, begins with the raw materials, which usually get into the production process from the silo storage via automatic feeders. Grinding, mixing etc. is fully automated, and mixing and stirring are usually automated production processes. An intermediate batch operation, for example emptying the agitators into containers with a capacity of up to 70̸ tons of chocolate, interrupts the continuous flow of material, but does not change the high mass potential of the manufacturing process. The first bottleneck problems with high material throughput can be seen on Subsequent injection or pouring process in which the unshaped mass is to be given a lumpy shape, that is to say divided into portions.

Wenn bis zu diesem Punkt des Produktionsprozesses der Materialfluss mit einfachen Mitteln bewältigt werden kann, meistens durch Rohrverbindungen, welche ein verhältnismässig einfaches Pipelining ermöglichen, das sich für den vollautomatischen Massentransport besonders gut eignet, können die stückigen Produkte, oder besser das portionierten Produkt, um es bspw. von stückiger Steinkohle, die auch pipeline-transportierbar ist, zu unterscheiden, nicht mehr mit den Massengutertransportmethoden transferiert werden.If up to this point in the production process the material flow can be managed with simple means, mostly through pipe connections, which enable a relatively simple pipelining, which is particularly well suited for the fully automated mass transport, the lumpy products, or better the portioned product, can be around it To distinguish, for example, from lumpy hard coal, which can also be transported by pipeline, can no longer be transferred using the bulk goods transport methods.

Eine zunehmende Verschärfung der Engpassproblematik zeigt sich besonders im Verpackungsabschnitt des Herstellungsprozesses, in welchem in einer einzigen Verpackungsstrasse bspw. ein Ausstoss von 50̸ Tonnen/Tag in bspw. 100 g Portionen die Bewältigung von 50̸0̸'0̸0̸0̸ Verpackungsvorgängen/Tag erfordert. In der Regel sind mehrere solcher Verpackungsstrassen installiert und auch simultan in Betrieb gesetzt.An increasing aggravation of the bottleneck problem is particularly evident in the packaging section of the manufacturing process, in which, in a single packaging line, for example, an output of 50̸ tons / day in, for example, 100 g portions requires the handling of 50̸0̸'0̸0̸0̸ packaging processes / day. As a rule, several such packaging lines are installed and also put into operation simultaneously.

Wenn schon bei der Portionierung der Materialfluss in mehrere Spritzstrassen aufgeteilt wurde, um durch simultane, parallele Arbeitsvorgänge Engpässe zu umgehen, so wird dies beim unvermeidbar seriellen Vorgang der Verpackung erst recht erzwungen. An jede Spritzstrasse schliessen sich daher mehrere parallel arbeitende Verpackungsstrassen an, in welchen die in diesem Beispiel produzierten Schokolodetafeln (Portionen) durch ein für hohe Verpackungsgeschwindigkeiten entwickeltes Flow-Pack-Verfahren eingepackt werden. In der Regel wird der Flowpackstrang anschliessend in die vorgesehenen Portionen zerschnitten und die losen Einzelprodukte in irgend einer Weise gesammelt.If the material flow has already been divided into several spray lines during portioning in order to avoid bottlenecks through simultaneous, parallel work processes, this is even more enforced in the inevitable serial process of packaging. Each spraying line is therefore followed by several packaging lines operating in parallel, in which the chocolate bars (portions) produced in this example are packed using a flow pack process developed for high packaging speeds. As a rule, the flow pack strand is then provided in the intended Cut up portions and collect the loose individual products in some way.

Hier setzt nun die erfinderische Idee ein. Ueblicherweise wird der Materialfluss verpackter Produkte, hier Schokoladentafeln, entweder vollautomatisch oder von Hand weiterverarbeitet. Sehr oft geschieht dies doch noch von menschlicher Hand, bspw. durch ganz konventionelles Abpacken in Schachteln etc., wo aus einer unhandlichen Vielstückigkeit (Schokoladetafeln) eine handlichere aber aufwendigere Wenigerstückigkeit (Schachteln) herbeigeführt wird. Gleich welcher Art die Verpackung nun geschieht, bei der Vereinzelung zu abpackbaren Portionen wird eine prozessinhärente Ordnung eigentlich zu früh aufgehoben.This is where the inventive idea comes in. The material flow of packaged products, here chocolate bars, is usually processed either fully automatically or by hand. Very often this is done by human hands, for example by conventional packaging in boxes, etc., where an unwieldy multi-piece (chocolate bars) results in a more manageable but more complex piece (boxes). Regardless of the type of packaging, when separating into packable portions, a process-inherent order is actually broken too early.

Mit prozessinhärenter Ordnung ist hier folgendes gemeint. Verschiedene Bearbeitungsschritte finden an verschiedenen Orten statt, die unter Umständen sehr nahe beieinander- oder sehr weit auseinanderliegen können. Das Material muss von einem Ver-(Be-)arbeitungsschritt zum anderen gefördert werden. Dabei sind zum Beispiel Lageänderungen oder dergleichen durchzuführen. Sie sind als Anschlussoperation an den nächsten Prozessschritt aufzufassen und repräsentieren eine bestimmte (transiente) Ordnung im Gesamtfluss. Eine Störung dieser Ordnung stört den Ablauf, ein Aufheben dieser Ordnung blockiert den Ablauf. Ordnende Eingriffe können als "eingebrachte" Ordnungselemente aufgefasst werden. Prozessinhärente Ordnungselemente dagegen sind im Prozessablauf verborgen schon vorhanden, müssen zur Nutzung aber speziell aufgesucht werden. Recht seiten liegen sie auf der Hand, meist derart selten, dass oft zusätzliche Ordnungselemente in einen Prozess eingebracht werden, wo eine prozessinhärente Ordnung eigentlich nutzbar gewesen wäre. Und was auch vorkommt, eine prozessinhärente Ordnung wird durch einen zusätzlichen Produktionsschritt aufgehoben (zerstört) und durch ein "eingebrachtes" Ordnungselement ersetzt.Process-inherent order means the following. Different processing steps take place in different places, which may be very close to each other or very far apart. The material must be conveyed from one processing step to another. For example, changes in position or the like are to be carried out. They are to be understood as a follow-up operation to the next process step and represent a certain (transient) order in the overall flow. A disturbance of this order interferes with the process, a cancellation of this order blocks the process. Organizing interventions can be understood as "introduced" organizational elements. On the other hand, process-inherent organizational elements are already hidden in the process flow, but must be specifically sought for use. They are obvious on the right-hand side, mostly so rarely that additional organizational elements are often introduced into a process where a process-inherent order could actually have been used. And whatever happens, a process-inherent order is created by an additional production step canceled (destroyed) and replaced by an "introduced" order element.

Die Erfindung stellt sich die Aufgabe, ein Verfahren zur übergangsmässigen Lagerung (Zwischenlagerung) eines Verpackungsverbundes bspw. Flowpack oder Schlauchbeutel anzugeben, bei dem solche Ordnungselemente genutzt und damit die Uebergabe des verpackten Materials in den früher oder später folgenden Verarbeitungsschritt wesentlich erweitert werden, wobei das Verfahren für einen Hochgeschwindigkeits-Verpackungsprozess besonders geeignet sein soll.The object of the invention is to provide a method for the transitional storage (intermediate storage) of a packaging assembly, for example a flow pack or tubular bag, in which such order elements are used and thus the transfer of the packaged material into the sooner or later subsequent processing step is significantly expanded, the method should be particularly suitable for a high-speed packaging process.

Ferner ist es Aufgabe der Erfindung, für die Durchführung des Verfahrens geeignete Mittel zu schaffen.It is also an object of the invention to provide suitable means for carrying out the method.

Ein Beispiel der Nutzung von prozessinhärenten Ordnungselementen wird an der Weiterverarbeitung eines Flowpackausstosses von Schokoladentafeln gezeigt. Jedoch ist die Erfindung keineswegs auf die Art des verpackten Gutes beschränkt, es kann sich um irgend einen zusammenhängenden Verpackungsstrang mit portionierten Produkten handeln.An example of the use of process-inherent organization elements is shown in the further processing of a flow pack output from chocolate bars. However, the invention is in no way limited to the type of the packaged goods, it can be any coherent packaging strand with portioned products.

Die Lösung der Aufgabe gemäss Erfindung, wird an diesem speziellen Beispiel gezeigt und ist durch die in den Patentansprüchen definierte Erfindung beschrieben.The achievement of the object according to the invention is shown using this specific example and is described by the invention defined in the patent claims.

Figur 1 zeigt die letzten Stationen eines Materialflusses in einem Herstellungsprozess und zwar ab der Portionierung einer Grundmasse (Schokolade) und die damit einhergehende Aufteilung in simultan arbeitende Fertigungstrassen. Diese Parallelführung beginnt bei den Tafelanlagen 1A bis 1D, die einen teigigen Materialfluss von bspw. 22,5 t/h aufnehmen und zu bestimmten Portionen verarbeiten. Jede Tafelanlage arbeitet auf je eine Verpackungsanlage, mit 3A bis 3D bezeichnet, wobei jede der dargestellten Verpackungsanlagen mehrere parallel arbeitende Verpackungsstrassen umfassen kann. In den Verpackungsstrassen wird das Produkt im Flow-Pack-Verfahren, einer Art Schlauchbeutelverpackung, mit hoher Verarbeitungsgeschwindigkeit eingehüllt. Die Verpackungsgeschwindigkeit in einer Verpackungsstrasse und damit ihr Ausstoss, beträgt typischerweise 1.0̸ bis 1.5 m/s. Die Produktströme 4A/a bis 4D/d am Ausgang der Verpackungseinheiten sollen nun folgendes zeigen. Ein kleinerer Produktstrom 4a wird bspw. in voller Ausstossgeschwindigkeit einer automatischen Grossabpackung 9 zugeführt; ein grösserer Produktstrom 4A kann aus irgendwelchen Gründen nicht sofort automatisch abgepackt werden und sollte deshalb in eine Zwischenlagerung für einen späteren Verpackungstermin gebracht werden.Figure 1 shows the last stages of a material flow in a manufacturing process, and that from the portioning of a base (chocolate) and the associated Division into simultaneous production lines. This parallel guidance begins with the table systems 1A to 1D, which take up a doughy material flow of, for example, 22.5 t / h and process it into certain portions. Each board system works on a packaging system, designated 3A to 3D, wherein each of the packaging systems shown can comprise several packaging lines operating in parallel. The product is encased in the packaging lines using the flow pack process, a kind of tubular bag packaging, at a high processing speed. The packaging speed in a packaging line and thus its output is typically 1.0̸ to 1.5 m / s. The product streams 4A / a to 4D / d at the exit of the packaging units should now show the following. A smaller product stream 4a is, for example, fed to an automatic large package 9 at full ejection speed; for some reason, a larger product stream 4A cannot be automatically packaged immediately and should therefore be put into intermediate storage for a later packaging appointment.

Somit stellt sich für den grösseren Produktstrom 4A nun das Problem der Weiterverarbeitung bspw. in einer Sortenmischstrasse 6 und/oder Zwischenlagerung in bspw. einem Zwischenlager 5 zur späteren Weiterverarbeitung in einer Sortenmischstrasse. Diese Zwischenlagerung dient als Zeitpuffer. Darin kann aber auch ein Transport enthalten sein, der sich über eine kürzere oder längere Distanz erstreckt. Das Verfahren gemäss Erfindung erlaubt nun solche Zwischenpufferungen durch Nutzung Prozessinhärenter Ordnungselemente fast beliebig durchzuführen, in dem bei deren Nutzung einerseits bei vollem Produktausstoss die Transfergeschwindigkeit vorübergehend herabgesetzt bzw. stillgelagt werden kann, um ihn andererseits an einem anderen Ort mit anderer Prozessgeschwindigkeit weiterzuführen. Dies ist mit der Sortenmischstrasse 6 angedeutet, in welcher Sorten A bis Q in bspw. zwei Materialströme 7,8 vermischt werden. Der Materialstrom 7 enthält bspw. Sorten F bis N, der Materialstrom 8 die Sorten A bis Q. In der Regel sind dies grosse Verpackungseinheiten mit 10̸0̸kg Schokolade und mehr, bestehend aus allen Sorten oder einem ausgewählten Teil davon.Thus, for the larger product stream 4A, there is now the problem of further processing, for example in a mixed-type mixing line 6 and / or intermediate storage in, for example, an intermediate store 5 for later further processing in a mixed-type mixing line. This intermediate storage serves as a time buffer. However, this can also include a transport that extends over a shorter or longer distance. The method according to the invention now allows such intermediate buffers to be carried out almost arbitrarily by using process-inherent order elements, in which when they are used, the transfer speed can be temporarily reduced or shut down when the product is fully discharged, and then continued at another location with a different process speed. This is with the mixed variety street 6 indicated in which types A to Q are mixed in, for example, two material flows 7,8. The material stream 7 contains, for example, types F to N, the material stream 8 the types A to Q. As a rule, these are large packaging units with 10̸0̸kg chocolate and more, consisting of all types or a selected part thereof.

Die Figuren 2a/b zeigen aus zwei Betrachtungsrichtungen eine typische Schlauchbeutelverpackung mit Einzel-Portionen 20̸A bis 20̸E usf., die in einem "Verpackingsschlauch" 22 untergebracht sind. Die einzelnen Portionen sind im Verpackungsschlauch durch Verschlusszonen 21A bis 21D usf. voneinander getrennt. Im üblichen Flowpackprozess trennt eine mit Prozessgeschwindigkeit gesteuerte Schneidvorrichtung den Flowpackverbund 22 in etwa mittig in den Verschlusszonen die Portionen voneinander. Diese Vereinzelung der Portionen galt bis lang als unabdingbar, da bei einer Ausstossgeschwindigkeit von 1 bis 1,5 m/s der zusammenhängende Flowpackverbund (Materialstrom) nicht beherrscht werden könnte.FIGS. 2a / b show a typical tubular bag packaging with individual portions 20̸A to 20̸E etc. from two viewing directions, which are accommodated in a “packaging tube” 22. The individual portions are separated from one another in the packaging tube by sealing zones 21A to 21D etc. In the usual flow pack process, a cutting device controlled at process speed separates the flow pack assembly 22 from the portions approximately in the middle in the closure zones. This separation of the portions has long been considered indispensable, since the continuous flow pack network (material flow) could not be mastered at an ejection speed of 1 to 1.5 m / s.

Gemäss Erfindung wird diese Vereinzelung jedoch gerade vermieden, um eine prozessinhärente Ordnung zu erhalten und zu nutzen. Es wird auf einen Schneidvorgang an dieser Stelle des Verarbeitungsprozesses verzichtet und die hohe Geschwindigkeit des Materialstroms durch Aufwickeln des Flowpackverbunds heruntergesetzt bis stillgelegt. Als prozessinhärentes Ordnungselement ist die unzerschnittene bzw. intakte Verschlusszone 21 zu betrachten. Die Gesamtheit der intakten Verschlusszonen 21A..21D..21n ordnet die verpackten Portionen in einer definierten Reihe zu einem strangförmigen Verbund.According to the invention, however, this separation is avoided in order to maintain and use a process-inherent order. There is no cutting process at this point in the processing process and the high speed of the material flow is reduced or shut down by winding up the flow pack assembly. The uncut or intact closure zone 21 is to be considered as a process-inherent order element. The entirety of the intact closure zones 21A..21D..21n arranges the packaged portions in a defined row to form a strand-like composite.

Zum Aufwickeln der Verpackungsstränge werden Wickelplatten benützt, auf welchen der Verpackungsstrang von innen nach aussen aufgewickelt wird. Die Wickelplatten haben vorzugsweise eine scheibenförmig runde Form, der Durchmesser ist auf das Produkt und auf die Lagerkapazität abgestimmt. Die Wickelplatten sind stapelbar ausgestaltet und können in bestimmten Ausführungsformen einen ebenen oder schwach geneigten Plattenboden aufweisen. Für die prinzipielle Darstellung des Verfahrens gemäss Erfindung zeigt Figur 3 einen schematisch dargestellten heb- und senkbaren Wickelplattenantrieb 40̸, in welchen die Platten zur Beladung vertikal von unten oder von oben eingeschoben bzw. eingespannt werden können. Die vom Wickelantrieb 40̸ freigegebenen vollgespulten Wickelplatten 30̸A bis 30̸F lassen sich zu einem Lager-Turm 45 stapeln, welcher auf einer Normpalette plaziert mit den üblichen Transportmitteln manipulierbar ist. Der Flowpackverbund wird in grossen Längen aufgewickelt und die einzelnen Wickel oder Spulen auf ihren Wickelplatten aufeinander gestapelt. Auf diese Weise lässt sich eine sehr raumdichte Lagerform von unvereinzelten Produkten erreichen. Die Produktform ist im wesentlichen diesselbe, wie sie im Produktionsprozess vorhanden ist, sodass an diese zwischengelagerten Produkt zu jeder Zeit der Prozess in der Prozessphase wieder aufgenommen werden kann, in welcher er verlassen (unterbrochen) wurde.Wrapping plates are used to wind up the packaging strands, on which the packaging strand is wound from the inside out. The winding plates preferably have a disc-shaped, round shape, the diameter is matched to the product and to the storage capacity. The winding plates are designed to be stackable and, in certain embodiments, can have a flat or slightly inclined plate base. For the basic illustration of the method according to the invention, FIG. 3 shows a schematically illustrated lifting and lowering winding plate drive 40̸, in which the plates can be inserted or clamped vertically from below or from above for loading. The fully wound winding plates 30̸A to 30̸F released by the winding drive 40̸ can be stacked to form a storage tower 45 which, when placed on a standard pallet, can be manipulated with the usual means of transport. The flowpack assembly is wound up in great lengths and the individual windings or coils are stacked on their winding plates. In this way, a very space-tight form of storage of uncommon products can be achieved. The product form is essentially the same as that which is present in the production process, so that the process can be resumed at any time in the intermediate phase of the process phase in which it was left (interrupted).

Der Plattenantrieb 40̸ ist wie die Gabel eines Gabelstaplers heb- und senkbar angeordnet (Pfeil B). Der Antrieb erfolgt bspw. durch einen Elektromotor 44 mit einem Zahnritzel 42 über einen Innenzahnkranz 43. Unterhalb seiner Innenausnehmung steht auf dem Boden ein Lagerturm 45 mit vollgespulten Wickelplatten 30̸A bis 30̸F. Der Wickelplattenantrieb 40̸ ist etwas über den fertiggestellten (obersten) Flowpackwickel angehoben worden, um von oben eine leere Wickelplatte 30̸ in den Antrieb einzusetzen. Nach dem Einspannen wird der von im Bild links schräg (Pfeil C) hereinlaufende Verpackungsstrang 22 eingefädelt und die Platte 30̸ zum Aufspulen in Rotation versetzt. Während des Wickelvorgangs bleibt die Wickelplatte im Wickelplattenantrieb "eingespannt" und sobald sie vollgespult ist, wird sie auf die vorangegangene, fertigbeladene Wickelplatte des Lagerturms 45 gestellt.Nachdem die letzte und oberste Wickelplatte gefüllt ist, wird der Wickelplattenantrieb, wie schon gezeigt, soweit angehoben (Doppelpfeil B), dass er über den Lagerturm 45 weggeschwenkt, oder der Lagerturm darunter weggefahren werden kann. Dann wird der Wickelplattenantrieb soweit abgesenkt, dass er wieder zum Auffüllen eine neuen Lagerturms bereit ist.The plate drive 40̸ is arranged like the fork of a forklift lift and lower (arrow B). It is driven, for example, by an electric motor 44 with a pinion 42 via an internal ring gear 43. Below its inner recess is a storage tower 45 with fully wound winding plates 30pulA to 30̸F. The winding plate drive 40̸ has been raised slightly above the finished (top) flow pack winding in order to insert an empty winding plate 30̸ into the drive from above. After clamping the im Left left (arrow C), the packaging strand 22 runs in at an angle and the plate 30̸ is set in rotation for winding. During the winding process, the winding plate remains "clamped" in the winding plate drive and as soon as it is fully wound, it is placed on the previous, fully loaded winding plate of the storage tower 45. Double arrow B) that it can be pivoted away over the storage tower 45, or the storage tower can be moved away below it. Then the winding plate drive is lowered until it is ready to fill a new storage tower again.

Der Wickelplattenantrieb 40̸, versetzt die Wickelplatte 30̸ in eine drehende Bewegung, wodurch ein zugeführter Flowpack-Strang sukzessive aufgewickelt wird. Zugunsten einer einfachen und verständlichen Darstellung sind die Proportion entsprechend verzeichnet. Die hier gezeichneten Wickelplatten 30̸ können eine Seitenlänge von ungefähr 2 bis 3 Metern aufweisen, die Stapelstützen 38 sind jedoch nur um die 15cm hoch. Auch nicht eingezeichnet sind Massnahmen zur Herstellung der nötigen Festigkeit der Platte, wie Verstrebungen, Versteifungen etc., um sie für eine Tragkraft von 20̸0̸ bis 30̸0̸kg palettiertes Material tauglich zu machen. Eine Vorrichtung zum Einfädeln des Verpackungsstrangs wird an einer späteren Stelle eingehend beschrieben.The winding plate drive 40̸ sets the winding plate 30̸ in a rotating movement, as a result of which a supplied flowpack strand is wound up successively. The proportion is recorded accordingly in favor of a simple and understandable representation. The winding plates 30̸ shown here can have a side length of approximately 2 to 3 meters, but the stack supports 38 are only 15 cm high. Also not shown are measures to produce the necessary strength of the plate, such as struts, stiffeners, etc., to make them suitable for a load capacity of 20̸0̸ to 30̸0̸kg palletized material. A device for threading the packaging strand will be described in detail at a later point.

Da die Wickelplatten "Verschiebeware" sind, sollte der Herstellungsaufwand pro Platte möglichst niedrig sein, das heisst, dass eine Wickelanlage möglichst viele Funktionen direkt am Wickelplattenantrieb 40̸ aufweisen soll, die Wickelplatten 30̸ selber nur die für die Be-,Entladung und Lagerung nötigsten Elemente umfassen. Alle anderen Funktionen sollen dem zentralen Wickelplattenantrieb 40̸ zugeordnet sein, der im Vergleich zur grossen Zahl der Wickelplatten nur in sehr geringer Stückzahl vorhanden sein muss.Since the winding plates are "movable goods", the manufacturing effort per plate should be as low as possible, that is to say that a winding system should have as many functions as possible directly on the winding plate drive 40̸, the winding plates 30̸ themselves only include the elements necessary for loading, unloading and storage . All other functions are to be assigned to the central winding plate drive 40̸ be, which only has to be available in very small numbers compared to the large number of winding plates.

Figur 4 zeigt nun in konkreter Form eine Anlage zum Auf- oder Abwickeln eines Flowpackverbundes 22. Auf je einer hier stilisiert dargestellten Hebebühne 31 sind auf Normpaletten 32 eine Anzahl Wickelplatten 50̸ aufgestapelt. Auf der rechts stehenden Hebebühne ist ein Vorrat leerer Wickelplatten zur Bewicklung bereitgestellt, auf der linksstehenden Hebebühne befinden sich, aufeinandergestapelt, bewickelte Wickelplatten. Darüber, auf einer Tragkonstruktion 35 angeordnet, befindet sich ein Wickelplattenantrieb, in seiner Gesamtheit mit 40̸ bezeichnet, sowie eine Zuführeinrichtung, die in ihrer Gesamtheit mit 41 bezeichnet ist. Der Wickelplattenantrieb 40̸ besteht im wesentlichen aus einem Antriebsmotor 46 und einer daran befestigten pneumatischen Welle 47, um damit nebst der Drehbewegung zum Wickeln eine Heb- und Senkbewegung vom und zum Lagerturm auszuführen. An dieser pneumatischen Welle können die Wickelplatten 50̸ an ihrem Wickelkern 51 eingespannt werden. Die Zuführeinrichtung 41 besteht im wesentlichen aus einem Antriebsmotor 48 zum Antrieb einer Schwenkweile 42, an welcher ein Schwenkarm 44 mit einer Greifvorrichtung 45 zum Einspannen des Wickelkerns 51 einer leeren Wickelplatte 50̸ angeordnet ist. Einer oder mehrere Wickelplattenantriebe 40̸ sind zur Zuführeinrichtung 41 so angeordnet, dass mit der ausgeführten Schwenkbewegung die Wickelplatten achsrichtig unter den Wickelplattenantrieb plaziert werden können. In diesem Beispiel wird von einer Zuführeinrichtung 41 nur ein Wickelplattenantrieb 40̸ versorgt. Gerade so gut könnten mit einer Zuführvorrichtung zwei Wickelplattenantriebe versorgt werden.FIG. 4 now shows in concrete form a system for winding or unwinding a flow pack assembly 22. A number of winding plates 50̸ are stacked on standard pallets 32 on each lifting platform 31 shown here. On the lifting platform on the right there is a supply of empty winding plates for wrapping, on the lifting platform on the left there are wound winding plates stacked on top of each other. Above, arranged on a support structure 35, there is a winding plate drive, designated in its entirety with 40̸, and a feed device, which is designated in its entirety with 41. The winding plate drive 40̸ consists essentially of a drive motor 46 and a pneumatic shaft 47 attached to it, in addition to the rotary movement for winding to perform a lifting and lowering movement from and to the storage tower. The winding plates 50 die can be clamped on their winding core 51 on this pneumatic shaft. The feed device 41 essentially consists of a drive motor 48 for driving a pivoting shaft 42, on which a pivoting arm 44 with a gripping device 45 for clamping the winding core 51 of an empty winding plate 50̸ is arranged. One or more winding plate drives 40̸ are arranged in relation to the feed device 41 in such a way that, with the pivoting movement carried out, the winding plates can be placed under the winding plate drive with the correct axis. In this example, only one winding plate drive 40̸ is supplied by a feed device 41. Two wrapping plate drives could be supplied with just one feed device.

Die Anlage funktioniert folgendermassen.The system works as follows.

Die bewickelten wie auch die leeren Wickelplatten sind aufeinander gestapelt und bilden so, wie vorher schon dargestellt und diskutiert, einen leicht manipulierbaren Lager-Turm mit unvereinzelten Schlauchbeuteln (Flowpack). Jeder Turm ist dafür vorzugsweise auf einer Normpalette plaziert, sodass er mit bspw. Gabelstaplern leicht transportiert werden kann. Die Normpaletten, zur Abgabe von leeren Wickelplatten von einem Leerturm und zur Aufnahme von bewickelten Platten an einen Lagerturm, sind auf je einer Hebebühne 31 plaziert. Die beiden Hebebühnen bewegen sich gegenläufig; während die eine Hebebühne leere Wickelplatten zuführt und sich dabei schrittweise anhebt, nimmt die andere Hebebühne bewickelte Wickelplatten auf und senkt sich dabei schrittweise ab. Mit der Zuführeinrichtung 41 wird vom Leerturm die oberste Wickelplatte 50̸ abgehoben, zum Wickelplattenantrieb 40̸ geschwenkt, dort an der pneumatischen Welle 47 angekoppelt und in Drehung versetzt. Der bandförmige Flowpackverbund 22 wird dann der aufnahmebereiten Wickelplatte 50̸ zugeführt, von deren Wickelkern 51 aufgenommen und aufgespult. Die Details der Zuführung, Einfädelung etc. werden mit Hilfe weiterer Figuren diskutiert. Es wird davon ausgegangen, dass die Ausgestaltung der pneumatischen Welle 47, die Antriebe 46,48 des Wickelplattenantriebs 40̸ und der Zuführeinrichtung 41, die Ausgestaltung der Hebebühnen 31 und deren Steuerung dem Fachmann bekannt sind und deshalb nicht eingehender besprochen werden müssen.The wound as well as the empty wrapping plates are stacked on top of one another and, as already shown and discussed above, form an easily manipulable storage tower with unspecified tubular bags (flow pack). For this purpose, each tower is preferably placed on a standard pallet so that it can be easily transported with forklifts, for example. The standard pallets, for delivering empty winding plates from an empty tower and for receiving wound plates to a storage tower, are each placed on a lifting platform 31. The two lifts move in opposite directions; while one lifting platform feeds empty wrapping plates and gradually rises, the other lifting platform picks up wound winding plates and lowers them gradually. With the feed device 41, the top winding plate 50platte is lifted from the empty tower, swiveled to the winding plate drive 40̸, coupled there to the pneumatic shaft 47 and set in rotation. The band-shaped flow pack assembly 22 is then fed to the ready-to-take-up winding plate 50 ', taken up by its winding core 51 and wound up. The details of feeding, threading, etc. are discussed with the help of further figures. It is assumed that the design of the pneumatic shaft 47, the drives 46, 48 of the winding plate drive 40̸ and the feed device 41, the design of the lifting platforms 31 and their control are known to the person skilled in the art and therefore need not be discussed in more detail.

Auf die dargestellte Weise ist es möglich, die aufgabenmässige Umgehung der prozesshindernden Vereinzelung zu erreichen und dies bei einem in voller Verarbeitungsgeschwindigkeit laufenden Fliessbetrieb. Dabei ist mit einer gleicherweise aufgebauten Wickel-Anlage eine Umkehrung des Prozesses (Abspulen) für die Weiterverarbeitung, das heisst die zeitlich aufgeschobene Vereinzelung zur Verpackung möglich. Dabei werden von einem Lagerturm 45 mit der Zuführ- bzw. Wegführeinrichtung 41 die vollgespulten Wickelplatten abgehoben und diese der Aufwickel- bzw. Abwickelvorrichtung 40̸ zugeführt. Dabei wird ein Turm mit leeren Wickelplatten für die weitere Verwendung entstehen.In the manner shown, it is possible to bypass the process-preventing separation in terms of the task, and this with a flow operation running at full processing speed. A reversal of the process (unwinding) for further processing is possible with a winding system of the same design, i.e. the deferred separation for packaging is possible. A storage tower 45 with the feed or Removal device 41, the fully wound winding plates are lifted and fed to the winding or unwinding device 40̸. This will create a tower with empty winding plates for further use.

Zur volltüchtigen Unterstützung eines Fliessbetriebs, muss der oben beschriebene Wickelvorgang zu jeder Zeit durchführbar sein, obwohl die Aufspultätigkeit und die Bildung von Lagertürmen chargen-betriebsähnliche Vorgänge sind. Um dies zu erreichen, müssen in alternierender Arbeitsweise mindestens zwei der eben beschriebenen Wickel-Anlagen pro Verpackungsmaschine vorgesehen sein. Eine solche Tandemeinrichtung mit Produktzuführungen ist von oben gesehen in Figur 5 dargestellt.To fully support a flow operation, the winding process described above must be feasible at all times, although the winding operation and the formation of storage towers are batch-like processes. In order to achieve this, at least two of the winding systems just described must be provided per packaging machine in an alternating mode of operation. Such a tandem device with product feeds is shown in FIG. 5 seen from above.

Figur 5 zeigt zwei Wickelplatten 50̸ ohne deren Wickelplatterantrieb 40̸ und dazu geordnete Zuführeinrichtung 41 für die leeren Wickelplatten 50̸. Eine eben vollgespulte Wickelplatte ist mit A bezeichnet und eine bereitstehende, noch leere Wickelplatte. Sie ist mit B bezeichnet und wird eben mit einem Flowpackverbund 22 beschickt. Dazu dienen den Wickelplatten zugeordnete Transportvorrichtungen 55A,55B für den Flowpackverbund 22, in diesem Beispiel ist es eine Tandemvorrichtung, die abwechselnd in Tätigkeit gebracht wird.FIG. 5 shows two winding plates 50̸ without their winding plate drive 40̸ and an associated feed device 41 for the empty winding plates 50̸. A winding plate that has just been wound is designated by A and a ready-made, still empty winding plate. It is labeled B and is just being fed with a flow pack assembly 22. For this purpose, transport devices 55A, 55B assigned to the winding plates serve for the flow pack assembly 22, in this example it is a tandem device that is alternately activated.

Die Transportvorrichtung 55A,55B besteht im wesentlichen aus angetriebenen, über Antriebs- und auch Umlenkrollen 56,57,57',57'' laufende Endlosbändern 551,552, zwischen denen der Flowpackverbund 22 sanft eingeschlossen der Wickelplatte 50̸ zugeführt wird. Diese beiden Transportvorrichtungen sind entsprechend ihrer momentanen Arbeitsposition mit 55A und 55B bezeichnet, in ihrer Ausgestaltung sind sie sich einander gleich. Ein äusseres 551 und ein inneres 552 Transportband sind als Endlosbänder über Antriebs- und Umlenkrollen 56,57,57',57'' geführt und durch Antriebsrollen 56 angetrieben. Ferner ist ein Teil der Transportvorrichtung, der der Wickelplatte zugewandte vordere Teil mit den Umlenkrollen 57', schwenkbar ausgestaltet; er kann in diesem Beispiel um die Umlenkrolle 57'' geschwenkt werden. Dem vorderen Teil der Tansportvorrichtung ist noch ein Anpressmittel 52 zugeordnet, um die Förderung des Anfanges des Verpackungsstronges (Flowpackverbundes) auch im Wippenanpressbereich zu gewöhrleisten. Auf das Problem der Auffädelung dieses Anfanges wird an späterer Stelle eingegangen. Am anderen, Ende, dem hinteren Teil der Transportvorrichtung mit den Antriebsrollen 56, ist ein Umlenkorgan 58 vorgesehen, das den durch eine Schneideinrichtung 59 laufenden Flowpackverbund 22 nach den Schneiden jeweils der zu füllenden, also leeren Wickelplatte zuführt. Mit der Ziffer 60̸ ist schliesslich ein Bereich eingegrenzt, der im Zusammenhang mit Figur 6 im Detail die Auffädelung des Flowpackverbundes in den Wickelkern 51 der Wickelplatte 50̸ zeigt.The transport device 55A, 55B essentially consists of driven endless belts 551, 522 running over drive and also deflection rollers 56, 57, 57 ', 57'', between which the flow pack assembly 22 is gently fed to the winding plate 50'. These two transport devices are designated 55A and 55B according to their current working position, in their design they are mutually exclusive equal. An outer 551 and an inner 552 conveyor belt are guided as endless belts over drive and deflection rollers 56, 57, 57 ', 57''and driven by drive rollers 56. Furthermore, part of the transport device, the front part facing the winding plate with the deflection rollers 57 ', is designed to be pivotable; in this example it can be pivoted around the deflection roller 57 ″. A pressure means 52 is also assigned to the front part of the transport device in order to ensure the promotion of the beginning of the packaging string (flow pack composite) also in the rocker pressure area. The problem of threading on this beginning will be discussed later. At the other end, the rear part of the transport device with the drive rollers 56, a deflection element 58 is provided which, after the cutting, feeds the flow pack assembly 22 running through a cutting device 59 to the winding plate to be filled, that is to say empty. Finally, the number 60̸ delimits an area which, in connection with FIG. 6, shows in detail the threading of the flowpack assembly into the winding core 51 of the winding plate 50̸.

Die Vorrichtung gemäss Figur 5 funktioniert folgendermassen.The device according to FIG. 5 functions as follows.

Das Momentanbild zeigt eben den Wechsel des Wickelvorgangs von einer vollgespulten Wickelplatte A auf eine bereitstehende leere Wickelplatte B. Der schwenkbare Teil der Transportvorrichtung 55A ist in Richtung des Schwenkpfeiles S an der Peripherie der Spule oder des Wickels anliegend. Ein durch den Schneidvorgang der Schneideinrichtung 59 getrennter Restteil des aufgewickelten Flowpackverbundes 22 läuft noch in den nun fertiggestellten Wickel ein. Der auf diese Weise neuentstandene Anfangsteil des zertrennten Flowpackverbundes 22 ist, durch das Umlenkorgan 58 umgelenkt, in die Transportvorrichtung 55B eingelaufen und wird nun der leeren Wickelplatte B zugeführt. Die Transportvorrichtung 55B ist mit dem schwenkbaren Vorderteil in Auffädelungsposition am Wickelkern 51 anliegend, der den ankommenden Flowpackverbund aufnimmt. Anschliessend geht die Wickelplatte in den Spulbetrieb über. Während dem Aufwickeln auf die Wickelplatte B, wird die vollgespulte Wickelplatte A, wie im Zusammenhang mit Figur 4 erklärt, über die pneumatische Welle auf den Vorratsturm abgesenkt und über die Zuführeinrichtung 41 durch eine neue leere Wickelplatte ersetzt. Die Transporteinrichtung 55A verbleibt bis zur Wiederaufnahme des Spulbetriebs auf den Wickelkern 51 eingeschwenkt in Bereitschaft, zur Auffädelung des im Fliessbetrieb neuerlich zu zertrennenden Flowpackstreifens. Die Steuerung der Schneideinrichtung 59 und des Umlenkorgans 58 geschieht über Sensoren, die entweder den Spulstand des Wickels oder die Position des schwenkbaren Teils der Transportvorrichtung abtasten.The instantaneous picture shows the change of the winding process from a fully wound winding plate A to a ready empty winding plate B. The pivotable part of the transport device 55A is adjacent to the periphery of the coil or the winding in the direction of the pivoting arrow S. A remaining part of the wound flow pack assembly 22 separated by the cutting process of the cutting device 59 is still running into the now finished roll. The newly created initial part of the separated flow pack assembly 22, deflected by the deflecting member 58, has entered the transport device 55B and is now the empty one Winding plate B supplied. The transport device 55B lies with the pivotable front part in the threading position on the winding core 51, which receives the incoming flow pack assembly. The winding plate then goes into winding mode. During the winding onto the winding plate B, the fully wound winding plate A, as explained in connection with FIG. 4, is lowered onto the storage tower via the pneumatic shaft and replaced by a new empty winding plate via the feed device 41. The transport device 55A remains in readiness until the winding operation is resumed on the winding core 51, in order to thread on the flowpack strip to be cut again in the flow operation. The control of the cutting device 59 and the deflection member 58 takes place via sensors which either scan the winding position of the winding or the position of the pivotable part of the transport device.

Die folgenden Figuren 6A/B/C zeigen ein Ausführungsbeispiel einer in ihrer Gesamtheit mit 60̸ (Fig. 5) bezeichneten Vorrichtung zum Auffädeln des Flowpackverbundes 22 auf den Wickelkern 51 der Wickelplatten 50̸. Die drei Figuren zeigen an derselben Vorrichtung drei aufeinanderfolgende Betriebszustände, an welchen auch das Funktionieren der Vorrichtung diskutiert wird.The following FIGS. 6A / B / C show an exemplary embodiment of a device, designated in its entirety with 60̸ (FIG. 5), for threading the flowpack assembly 22 onto the winding core 51 of the winding plates 50̸. The three figures show three successive operating states on the same device, on which the functioning of the device is also discussed.

Die Vorrichtung gemäss Figur A zeigt den vorderen, schwenkbaren Teil der Transportvorrichtung 55 mit den Umlenkrollen 57' und dem Führungsorgan 52. Der Wickelkern 51 ist hier ähnlich wie ein Uhrfedergehäuse ausgestaltet. An einem Federkern 61 ist eine Spiralfeder 62 mit Befestigungsmitteln 63 befestigt und in mehreren Spiralen um den Federkern 61 (hier noch lose) aufgewickelt. Ein den Federkern und die Feder abdeckendes Gehäuse 64, mit bspw. einem Deckel 68 für Kontroll- und Servicezugang, weist für den Austritt der Spiralfeder 62, eine schlitzförmige Oeffnung 65 auf, an deren einen Seite ein Führungs- oder Gleitkeil 66 angeordnet ist. Die Spiralfeder 62 ist am nicht befestigten Ende aus dem Federgehäuse herausgezogen und weist ein geeignetes Element 69 auf, dass die Spiralfeder 62 trotz der auf sie wirkenden Rückholkraft nicht ganz in das Gehäuse zurückgezogen werden kann (zum Beispiel durch einen Anschlag). Ferner ist das ausserhalb des Federgehäuses verbleibende Ende der Spiralfeder, wie auch in Figur 7 dargestellt, mit einem Ankuppelungsmittel 67, das durch eine Zugbewegung lösbar ist, an einer zusätzlichen Hilfsvorrichtung 70̸ befestigbar Diese Hilfsvorrichtung 70̸ besteht aus einem motorisch angetriebenen Endlosband 71, das um zwei Umlenkrollen 72 geführt und bspw. über eine Antriebssaite 73 von einem Motor 74 antreibbar ist. Das Ankuppelungsmittel 67 kann in diesem Fall aus dem bekannten Klettenverschluss bestehen (auch ein Haftmagnet ist geeignet), der durch Abreissen einfach und mit wenig Kraft lösbar ist und auch wieder beliebig mit dem Endlosband 71 vereinigt werden kann. Das Endlosband 71 dient zum Herausziehen der Spiralfeder in Pfeilrichtung aus dem Federgehäuse (entgegen der Förderrichtung des Förderbandes 552) unter gleichzeitigem Aufspeichern einer Rückholkraft. Die herausgezogene Spiralfeder deckt das Endlosband 71 in seiner Breite und einem Teil seiner Länge vollständig ab. Um eine möglichst kurze Bauweise dieser Hilfsvorrichtung zu ermöglichen, wird das Förderband 552 in zwei im Abstand zueinander parallellaufenden Riemen 552',552'' aufgeteilt, zwischen welchen das Endlosband 71 angeordnet ist (Fig.7). So kann kann beim Ausziehen der Spiralfeder 62 auch das Rücktrum des Endlosbandes 71 genützt werden, an welchem ein an der Spiralfeder angeordnete Ankuppelungsmittel 67 mit dem Endlosband 71 im Eingriff gezeigt ist (siehe Figur 6C). Die Steuerung der Hilfsvorrichtung geschieht nach einem dem Fachmann geläufigen Vorgehen.The device according to FIG. A shows the front, pivotable part of the transport device 55 with the deflection rollers 57 'and the guide member 52. The winding core 51 is configured here similarly to a clock spring housing. A spiral spring 62 is fastened to a spring core 61 with fastening means 63 and wound in several spirals around the spring core 61 (here still loosely). A housing 64 covering the spring core and the spring, for example with a cover 68 for Control and service access has a slot-shaped opening 65 for the exit of the spiral spring 62, on one side of which a guide or sliding wedge 66 is arranged. The spiral spring 62 is pulled out of the spring housing at the unattached end and has a suitable element 69 that the spiral spring 62 cannot be fully retracted into the housing (for example by a stop) despite the return force acting on it. Furthermore, the end of the spiral spring remaining outside the spring housing, as also shown in FIG. 7, can be fastened to an additional auxiliary device 70̸ with a coupling means 67, which can be released by a pulling movement.This auxiliary device 70̸ consists of a motor-driven endless belt 71, which by two Deflection rollers 72 are guided and can be driven by a motor 74, for example, via a drive string 73. In this case, the coupling means 67 can consist of the known Velcro fastener (a holding magnet is also suitable), which can be detached easily and with little force by tearing off and can also be combined again with the endless belt 71 as desired. The endless belt 71 serves to pull the spiral spring out of the spring housing in the direction of the arrow (counter to the conveying direction of the conveyor belt 552) while simultaneously storing a return force. The pulled-out coil spring completely covers the endless belt 71 in its width and part of its length. In order to enable the construction of this auxiliary device to be as short as possible, the conveyor belt 552 is divided into two belts 552 ', 552''which run parallel and at a distance from one another and between which the endless belt 71 is arranged (FIG. 7). Thus, when the spiral spring 62 is pulled out, the back strand of the endless belt 71 can also be used, on which a coupling means 67 arranged on the spiral spring is shown in engagement with the endless belt 71 (see FIG. 6C). The auxiliary device is controlled according to a procedure familiar to the person skilled in the art.

Während nun Figur 6a die Auffädelvorrichtung 60̸ in ihrer Bereitschaftsposition zeigt, ist sie in Figur 6B schon in Aktion, um einen ankommenden Flowpackverbund 22 auf den Wickelkern 51 aufzufädeln. In einer vorbereitenden Phase, kurz vorher, wurde mittels der Hilfsvorrichtung 70̸ die am Endlosband 71 befestigte Spiralfeder 62 um etwas mehr als die Länge des Wickeldornumfanges aus dem Federgehäuse herausgezogen. Der vordere Teil des ankommenden Flowpackverbundes 22 läuft, angetrieben von den Riemen 552',552'' und gehalten vom Anpressmittel 52 auf die Spiralfeder 62 auf. Praktisch gleichzeitig beginnt sich der Wickelkern 51 im Gegenuhrzeigersinn (Drehpfeil) zu drehen und die Hilfsvorrichtung bringt die Feder 62 durch eine Richtungsumschaltung des Endlosbandes 71 in Richtung Federgehäuse bzw. zum Wickeldorn zurück. Bei diesem Vorgang wird der Flowpackverbund 22 sanft an den sich in Aufspulrichtung drehenden Wickelkern angedrückt, wobei die um etwas mehr als eine Umfanglänge aus dem Federgehäuse herausgezogene Spiralfeder, die immer noch am Endlosband 71 der Hilfsvorrichtung befestigt ist, dafür sorgt, dass der Flowpackverbund am Wickelkern angedrückt bleibt.6a shows the threading device 60̸ in its ready position, in FIG. 6B it is already in action to thread an incoming flow pack assembly 22 onto the winding core 51. In a preparatory phase, shortly beforehand, the spiral spring 62 attached to the endless belt 71 was pulled out of the spring housing by a little more than the length of the winding mandrel circumference by means of the auxiliary device 70̸. The front part of the incoming flow pack assembly 22 runs, driven by the belts 552 ', 552' 'and held by the pressing means 52 on the spiral spring 62. Practically at the same time, the winding core 51 begins to rotate in the counterclockwise direction (rotating arrow) and the auxiliary device returns the spring 62 by changing the direction of the endless belt 71 in the direction of the spring housing or to the winding mandrel. In this process, the flow pack assembly 22 is pressed gently against the winding core rotating in the winding direction, the spiral spring which is pulled out of the spring housing by a little more than a circumferential length and which is still attached to the endless belt 71 of the auxiliary device, ensuring that the flow pack assembly on the winding core remains pressed.

Dieser Teil des Vorgangs ist sehr gut in Figur 6C zu sehen, bei welcher schon eine erste Spulenlage des Flowpackverbundes 22 um den Wickelkern 51 liegend gezeigt ist. Das an der Spiralfeder 62 befestigte, lösbare Ankuppelungsmittel 67 ist gerade im Begriff sich vom immer noch mitlaufenden Endlosband 71 zu lösen. Dabei wird sich der als Aufwickelhilfe dienende Spiralfederteil auch kurzzeitig von der ersten Spulenlage ablösen, um dann zwischen der ersten und zweiten Spulenlage teilweise mit eingewickelt zu werden. Beim später erfolgenden Abwickeln des aufgewickelten Produktes, wird dieser Spiralfederteil wieder in das Federgehäuse zurückgezogen und kann so wieder in die Ausgangsposition zurück gebracht werden, wie dies in Figur 6A gezeigt ist.This part of the process can be seen very well in FIG. 6C, in which a first coil layer of the flow pack assembly 22 is already shown lying around the winding core 51. The detachable coupling means 67 attached to the spiral spring 62 is just about to be released from the endless belt 71 which is still running. In this case, the spiral spring part serving as a winding aid will also detach itself briefly from the first coil layer, in order to then be partially wrapped up between the first and second coil layers. When the wound product is later unwound, this spiral spring part is pulled back into the spring housing and can thus be brought back into the starting position, as shown in FIG. 6A.

Es handelt sich gemäss Erfindung ganz generell um ein Verfahren zum Ordnen eines zusammenhängenden Verpackungsstranges zur Ein- und Auslagerung in Lagereinheiten oder zur Zwischenpufferung während eines Verpackungsvorganges, der die Eigenheit aufweist, dass vor dem Zerschneiden in Produktportionen der mit voller Prozessgeschwindigkeit ausgegebene Verpackungsstranges auf Wickelplatten aufgewickelt und der gebildete Wickel zwischengelagert wird, um ihn weiteren Verfahrensschritten, bspw. eine vorgesehene Vereinzelung, in beliebigem Zeitabstand mit beliebiger Prozessgeschwindigkeit zuzuführen. Die das Verfahren durchführende Vorrichtung ist bestimmt durch einen Wickelplattenantrieb 40̸ und durch diesen antreibbare Wickelplatten 50̸ zum Aufwickeln eines zusammenhöngenden Verpackungsstranges 22, sowie eine Zuführeinrichtung 41 zum Zuführen von leeren Wickelplatten 50̸ an den Wickelplattenantrieb 40̸ und eine Transportvorrichtung 55A,55B zum Zuführen eines Verpackungsstranges 22 an die Wickelplatten 50̸. Einem Wickelplattenantrieb 40̸ können auch mehrere Zuführeinrichtungen 41 zugeordnet sein.According to the invention, it is generally a method for arranging a coherent packaging strand for storage and retrieval in storage units or for intermediate buffering during a packaging process, which has the peculiarity that before being cut into product portions, the packaging strand that is output at full process speed is wound onto winding plates and the coil formed is temporarily stored in order to feed it to further process steps, for example a proposed separation, at any time interval at any process speed. The device carrying out the method is determined by a winding plate drive 40̸ and winding plates 50̸ which can be driven by it for winding a coherent packaging strand 22, as well as a feed device 41 for feeding empty winding plates 50̸ to the winding plate drive 40̸ and a transport device 55A, 55B for feeding a packaging strand 22 the winding plates 50̸. A plurality of feed devices 41 can also be assigned to one winding plate drive 40̸.
