Zum Verpacken langgestreckter Güter - wie Standen, Profile, Drahtabschnitte, Holzleisten, längere Artikel im Lebensmittelbereich - ist es seit langem bekannt, das langgestreckte Gut durch einen den Verpackungswerkstoff führenden Wickelring zu fördern unter Erzielung eines wendelförmigen Umwickelns des langgestreckten Gutes. Auch sind schlauchartige Verpackungen bekannt, die in ihrem Inneren das langgestreckte Gut aufnehmen. Eine solche Vorrichtung ist beispielsweise aus der US 4,610,124 bekannt. Mittels dieser Vorrichtung wird eine Schlaufe aus dem Verpackungswerkstoff gebildet. Die Trennung des Verpackungswerkstoffes wird nach einem Schließen der Schlaufe auf der Abführseite des Verpackungswerkstoffes vorgenommen. Die GB 452 555 beschäftigt sich mit der Verpackung von Rund- oder Ovalgütern. Hierzu wird zunächst ein Verpackungsabschnitt abgetrennt und dann zugeführt. Weiter ist aus der US 3,566,752 eine zur Herstellung eines bestimmten, mit einem Aufreißstreifen versehenen Verpackungsmaterials dienende Vorrichtung bekannt.For packaging elongate goods - such as stands, profiles, wire sections, wooden strips, longer items in the food industry - it has long been known to promote the elongated product by a packaging material leading the winding ring to achieve a helical wrapping of the elongated material. Also tube-like packaging are known, which absorb the elongated good in their interior. Such a device is for example from the US 4,610,124 known. By means of this device, a loop is formed from the packaging material. The separation of the packaging material is made after closing the loop on the discharge side of the packaging material. The GB 452 555 deals with the packaging of round or oval goods. For this purpose, a packaging section is first separated and then fed.

Dem Gegenstand der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Verfahren und eine Vorrichtung der eingangs genannten Art so auszugestalten, dass kurzfristig und kostensparend Langgüter verpackbar sind.The object of the invention is based on the object, a generic method and an apparatus of the type mentioned in such a way that short-term and cost-saving long goods are packaged.

Diese Aufgabe ist beim Gegenstand des Anspruches 1 bzw. 16 gelöst.This object is achieved in the subject matter of claim 1 or 16.

Zufolge derartiger Ausgestaltung ist ein Verfahren angegeben, welches sich speziell zum Verpacken langgestreckter Güter eignet. Insbesondere kommen hierbei aus der Extrusionsmaschine herauslaufende Profile in Betracht, welche Profile eine Länge von mehr als drei Metern haben können. Ebenso ist es möglich, dass mehrere Extrusionsprofile in Nebeneinanderlage umhüllt werden können. Im Einzelnen läuft das Verfahren so ab, dass zunächst der Verpackungswerkstoff in einer Bahn quer zur Längserstreckung des Langgutes zugefördert wird. Diese Bahn bildet auf dem Förderweg eine nach oben offene Schlaufe, in welche das Langgut eingelegt wird. Danach werden gegenüberliegende Enden der Schlaufe gegeneinander gefahren. Es erfolgt danach eine Trennung auf der Zuführseite des Verpackungswerkstoffes, so dass die Schlaufenenden zur Sicherung an dem Langgut, eventuell bestehend aus mehreren Extrusionsprofilen, miteinander verbunden werden. Auf diese Weise erhält das Langgut kurzfristig und kostensparend die umhüllende Verpackung. Sie bringt mehr Schutz als eine wendelförmig aufgebrachte Verpackung. Um auch ein oder beide Stirnenden des Langgutes zu schützen, wird der Verpackungswerkstoff, welcher vorzugsweise von einer Vorratsrolle abgezogen wird, mit einem axialen Überstand bezüglich der Längsachse des Langgutes im Hinblick auf das vordere und/oder hintere Ende zugefördert. Als Material für den Verpackungswerkstoff kann eine Kunststofffolie, Stoffbahn oder eine Papierbahn dienen. Handelt es sich bezüglich des Materials um eine Kunststofffolie, bietet es sich erfindungsgemäß an, dass die Schlaufenenden durch Schweißen miteinander verbunden werden. Die Verschweißung erstreckt sich dabei über die gesamte Breite der Kunststofffolie und damit auch über die Länge des Langgutes. Eventuell wäre auch eine punktuelle oder teilweise Verschweißung über die Breite der Kunststofffolie möglich. Ferner können die über das Langgut vorstehenden Enden des kunststoffartigen Verpackungswerkstoffes verschweißt werden, so dass das Langgut in einem vollständig geschlossenen Sack einliegt und demgemäß einen hohen Schutz erhält. Wird eine Papierbahn als Verpackungswerkstoff gewählt, so bietet es sich an, die Schlaufenenden durch Kleben miteinander zu verbinden. Hierzu kann man sich beispielsweise eines doppelseitigen Klebestreifens bedienen. Es ist jedoch auch eine aufgebrachte Nassverklebung möglich. Bevorzugt wird ein Verpackungswerkstoff gewählt, dessen Bahnbreite der Länge des Langgutes angepaßt ist. Sollen zum Beispiel jedoch noch Langgüter größerer Länge nach dem erfindungsgemäßen Verfahren umhüllt werden, so wäre es möglich, mehrere Folien bzw. Papierbahnen nebeneinander einlaufen zu lassen. Diese können dann, wenn eine Überlappung vorgesehen wird, miteinander verklebt oder verschweißt werden. Möglich ist es auch, dass ein Klebeband gleichzeitig mit einläuft und einander benachbarte Längsabschnitte der Folienbahnen miteinander verbindet. Im Detail arbeitet das Verfahren in der Weise, dass der Verpackungswerkstoff über einen Zuführtisch zugefördert wird und in Einlaufrichtung von einem weiter vorne angeordneten Halterungsteil gehaltert wird, mit einem freilaufenden Abschnitt zwischen dem Halterungsteil und dem Zuführtisch. Dieser freilaufende Abschnitt dient der Übergabe des Langgutes an den Verpackungswerkstoff. Diesem Übergeben kommt der Sachverhalt entgegen, dass der freilaufende Abschnitt derart zugeführt wird, dass sich bereits vor Einlegen des Langgutes die Schlaufe bildet. Also wird für das Langgut eine Tasche geformt, welche in ihrer Beschaffenheit auf die Abmessungen des Langgutes abgestimmt ist. Eine Doppelfunktion erfüllt der Zuführtisch dadurch, dass nach Einlegen des Langgutes die Schlaufe durch Verfahren des Zuführtisches gegen das Halterungsteil geschlossen wird. Einerseits führt der Zuführtisch den Verpackungswerkstoff beim Zufördern. Andererseits wird durch ihn infolge des Abstandes zum Halterungsteil die Schlaufe gebildet, welche durch den Zuführtisch durch Vorfahren desselben wiederum geschlossen wird. Auf diese Weise wird ein geschlossener Sack zur Aufnahme des Langgutes geformt. Wenn dabei die Schlaufe durch den Zuführtisch klemmend geschlossen wird, kann man auf zusätzliche Verschlussbauteile verzichten, was sich verfahrenstechnisch als günstig erweist. Nach diesem Schließen wird der Zuführtisch zusammen mit dem Halterungsteil in Fertigstellungsposition verfahren. Auch diese Verlagerung wird ausgenutzt, im Zuge des Verfahrens in die Fertigstellungsposition zugleich Verpackungsmaterial nachzuziehen. In dieser Fertigstellungsposition können weitere Verfahrensschritte vorgenommen werden. Es kann dort eine Verbindung von zugeordneten Endabschnitten der Schlaufe durchgeführt werden, nachdem zuvor zulaufseitig eine Abtrennung des Verpackungswerkstoffes durchgeführt wurde. Diese Fertigstellungsposition eignet sich insbesondere auch dafür, einen Verschluss der Schlaufe an einem oder beiden Enden, die Stirnseiten verschließend, vorzunehmen. Dieses Verschließen kann je nach eingesetztem Verpackungsmaterial in der geeigneten Weise geschehen. Erst durch Lösen der Klemmhalterung wird anschließend das verpackte Langgut zum Abtransport freigegeben. Einhergehend mit diesem Verfahrensschritt wird das verpackte Langgut zum Abtransport durch Lösen der Klemmhalterung auf einen mit dem Zuführtisch verbundenen Abnahmetisch abgelegt. Von hier aus kann das umhüllte Langgut, welches beispielsweise Extrusionsprofile sein können, bequem abgenommen werden.According to such a configuration, a method is specified, which is particularly suitable for the packaging of elongated goods. In particular, profiles coming out of the extrusion machine come into consideration, which profiles can have a length of more than three meters. It is also possible that several extrusion profiles can be wrapped in juxtaposition. Specifically, the method is such that initially the packaging material is conveyed in a path transverse to the longitudinal extent of the long material. This web forms on the conveyor an upwardly open loop, in which the long goods is inserted. Thereafter, opposite ends of the loop are driven against each other. There is then a separation on the feed side of the packaging material, so that the loop ends are connected to each other for securing to the long goods, possibly consisting of several extrusion profiles. In this way, the long goods receive short-term and cost-saving the wrapping packaging. It provides more protection than a helically applied packaging. In order to protect one or both ends of the long goods, the packaging material, which is preferably is withdrawn from a supply roll, with an axial projection with respect to the longitudinal axis of the long material with respect to the front and / or rear end conveyed. As a material for the packaging material can serve a plastic film, fabric or a paper web. If the material is a plastic film, it is in accordance with the invention that the loop ends be joined together by welding. The welding extends over the entire width of the plastic film and thus over the length of the long goods. Possibly also a selective or partial welding over the width of the plastic film would be possible. Furthermore, the over the long goods protruding ends of the plastic-like packaging material can be welded, so that the long goods rests in a completely closed bag and accordingly receives a high protection. If a paper web is chosen as the packaging material, then it is advisable to connect the loop ends by gluing together. For this one can use, for example, a double-sided adhesive strip. However, it is also an applied wet bonding possible. Preferably, a packaging material is selected whose web width is adapted to the length of the long goods. However, if, for example, even long goods of greater length are to be enveloped by the method according to the invention, it would be possible to run several films or paper webs next to one another. These can then, if an overlap is provided, glued or welded together. It is also possible that an adhesive tape runs in at the same time and connects adjacent longitudinal sections of the film webs to one another. In detail, the method operates in such a way that the packaging material is conveyed via a feed table and is supported in the inlet direction by a further forwardly arranged holding part, with a free-running section between the holding part and the feed table. This free-running section serves to transfer the long goods to the packaging material. This transference comes the facts contrary to that the free-running section is supplied in such a way that already forms the loop before inserting the long goods. So a bag is formed for the long goods, which is tuned in their nature to the dimensions of the long goods. A double function is fulfilled by the feed table in that, after inserting the long goods, the loop is closed by moving the feed table against the holding part. On the one hand, the feed table guides the packaging material during feeding. On the other hand, the loop is formed by him as a result of the distance to the support member, which in turn is closed by the feed table by ancestors thereof. In this way, a closed bag is formed for receiving the long goods. If the loop is closed by clamping by the feed table, one can dispense with additional closure components, which proves to be favorable in terms of process engineering. After this closing, the feed table is moved together with the mounting part in the finished position. Also, this shift is exploited, at the same time nachzug packaging material in the course of the procedure in the finishing position. In this finishing position further process steps can be made. There may be carried out a connection of associated end portions of the loop, after previously on the upstream side a separation of the packaging material has been carried out. This finishing position is particularly suitable for making a closure of the loop at one or both ends, occluding the end faces. This sealing can be done depending on the packaging material used in the appropriate manner. Only by loosening the clamp, the packaged long goods is then released for removal. Along with this method step, the packaged long goods are stored for removal by loosening the clamp on a connected to the feed table acceptance table. From here, the coated long goods, which may be extrusion profiles, for example, are easily removed.

Vorzugsweise werden mindestens drei jeweils den Zuführtisch ausbildende Elemente vorgesehen, die jeweils zum Erzielen der Klemmhalterung geeignet gestaltet sind und zyklisch verfahren werden, um unter Nutzung derselben Elemente eine jeweils neue Verpackung herzustellen. Dieses zyklische Verfahren geschieht also schrittweise mittels identisch gestalteter Elemente, welche während des zyklischen Verfahrens unterschiedliche Funktionen haben. Auch kann das Halterungsteil den Verpackungswerkstoff mittels Unterdruck halten, weiter alternativ auch beispielsweise durch Ausbildung des Halterungsteiles in Form einer Nagelleiste oder dergleichen. In einem alternativen Verfahrensablauf verfährt das Halterungsteil im Zuge des Verfahrens in die Fertigstellungsposition ebenfalls zumindest teilweise mit, dies gegebenenfalls unter weiterem Halten des Verpackungswerkstoffes bis zum Ende des Verfahrweges, zufolge dessen rückwärtig des Halterungsteils Verpackungswerkstoff von einer Vorratsrolle oder dergleichen nachgezogen wird. Diesbezüglich erweist es sich weiter als vorteilhaft, wenn nach einem Abtrennen des Verpackungswerkstoffes das Halterungsteil in seine Anfangsposition zurückverfahren wird. Entsprechend wird mittels des bei der Vorverlagerung des Halterungsteiles nachgezogenen Verpackungswerkstoff-Abschnittes im Zuge des Rücklaufens des Halterungsteiles in die Anfangsposition eine Schlaufe vorgeformt. Bei der Verschweißung der Schlaufenenden wird der Selbstaufstelleffekt des Verpackungswerkstoffes genutzt. Darüber hinaus kann die Schweissvorrichtung auch einen Anhebelfinger oder dergleichen aufweisen, mit welchem die Schlaufenenden angehoben werden.Preferably, at least three elements each forming the feed table are provided, which are respectively designed to achieve the clamp holder and are cyclically moved to produce a new packaging using the same elements. This cyclic process thus takes place stepwise by means of identically designed elements which have different functions during the cyclic process. Also, the support member may hold the packaging material by means of negative pressure, further alternatively, for example, by forming the support member in the form of a nail bar or the like. In an alternative procedure, the support member moves in the course of the process in the finishing position also at least partially, this optionally with further holding the packaging material to the end of the travel, according to the rear of the support part packaging material is drawn from a supply roll or the like. In this regard, it proves to be further advantageous if after a separation of the packaging material, the support member is returned to its initial position. Accordingly, a loop is preformed by means of the trailing in the forward displacement of the support part packaging material section in the course of the return of the support member in the initial position. When welding the loop ends, the self-assembly effect of the packaging material is used. In addition, the welding device may also have a lifting finger or the like, with which the loop ends are lifted.

Die Vorrichtung zur Durchführung des Verfahrens zeichnet sich durch einen Zuführtisch aus, über welchen Verpackungswerkstoff zuläuft, wobei weiter in Zulaufrichtung ein Halterungsteil vorgesehen ist, in welchem ein Ende des Verpackungswerkstoffes gehaltert ist unter Bildung eines freilaufenden Abschnittes zwischen Halterungsteil und Zuführtisch und wobei weiter das Verpackungsmaterial quer zu einer Längserstreckung des Langgutes zugefördet wird. Wesentlich ist, dass der Zuführtisch und zumindest ein Teil des Halterungsteils gemeinsam in eine weitere sich in Zuführrichtung anschließende Position verfahrbar sind. Die Zuförderung des Verpackungsmaterials, also des Verpackungswerkstoffes, geschieht quer zur Längserstreckung des Langgutes. Bevorzugt werden mit der Vorrichtung aus einer Herstellungsmaschine kommende Extrusionsprofile umhüllt, welche bei ihrer Lagerung und Transport vor schädigenden äußeren Einflüssen geschützt werden sollen. Bautechnisch günstig ist es, dass der Zuführtisch und das Halterungsteil in Zuführrichtung relativ zueinander verfahrbar sind zum Schließen der Schlaufe. Das Schließen derselben kann dabei günstig durch Klemmwirkung erzeugt werden.The device for carrying out the method is characterized by a feed table over which packaging material tapers, wherein further in the feed direction, a support member is provided, in which one end of the packaging material is supported to form a free-running portion between the support member and feed table and further wherein the packaging material transversely to a longitudinal extent of the long material is conveyed. It is essential that the feed table and at least a portion of the support member are moved together in a further subsequent in the feed direction position. The delivery of the packaging material, so the packaging material, is done transversely to the longitudinal extent of the long goods. Preference is given to the device from a manufacturing machine coming extrusion profiles wrapped, which should be protected during their storage and transport from harmful external influences. It is advantageous from a structural point of view that the feed table and the holding part can be moved relative to one another in the feed direction for closing the loop. The closing of the same can be generated favorably by clamping action.

Im Einzelnen verfügt die Vorrichtung über mindestens drei verfahrbare Zuführtisch-Elemente, die jeweils einen Zuführtisch und zumindest einen Teil des Halterungsteils ausbilden, welches Halterungsteil bspw. durch eine Rolle oder Walze bzw. über die Breite des Zuführtisches gleichmäßig angeordnete Walzenabschnitte gebildet sein kann. Alternativ kann das Halterungsteil auch durch einen Abschnitt des Zuführtisches selbst gebildet sein. Die Zuführtisch-Elemente sind untereinander gleich gestaltet und beinhalten zumindest einen Teil des Halterungsteil. Um nach Schließen der Schlaufe und Verfahren des Zuführtisches in die anschließende Position den Verbindungsvorgang der Schlaufenenden vornehmen zu können, ist eine Schneidvorrichtung vorgesehen. Diese trennt die zugeführte Verpackungsbahn an der vorgegebenen Stelle. Hierzu ist die Schneidvorrichtung in Förderungsrichtung jenseits des Halterungsteils vorgesehen. Die Zuführtisch-Elemente sind so der Vorrichtung zugeordnet, dass sie zyklisch verfahrbar sind. Sie übernehmen je nach durcgeführtem Taktschritt eine andere Funktion. Sie sind bevorzugt - bei Betrachtung eines ausgewählten Punktes eines Zuführtisch-Elementes - in einer Vertikalebene zyklisch verfahrbar. So kann auch der Zustand eintreten, dass ein nach unten verfahrenes Zuführtisch-Element entgegen der Förderrichtung bewegbar ist. Diese Bewegung stört jedoch nicht den Arbeitsablauf der Vorrichtung. Ferner ist die Vorrichtung so beschaffen, dass ein nach unten verfahrenes Zuführtisch-Element vor einer Verpackungsmaterial-Vorratsrolle vertikal in Aufwärtsrichtung verfahrbar ist. Es nimmt dann die Position des Zuführtisches ein, über welchen das Verpackungsmaterial zugefördert wird. Weiterhin kann ein Zuführtisch-Element unterhalb des Zuführtisches einen Ablagetisch aufweisen. Dieser dient bei in der entsprechenden Position befindlichem Zuführtisch-Element der bequemen Abnahme des fertig verpackten Langgutes. Zur Bildung des Halterungsteils weist die Vorrichtung eine Klemmwalze auf, die mit dem Teil des Halterungsteils in dem Zuführtisch-Element zusammenwirkt, so bspw. mit einer Gegenwalze. Es ist also nur eine einzige Klemmwalze vorgesehen, die nacheinander mit den Gegenwalzen bzw. Teilen des Halterungsteils der Zuführtisch-Elemente zusammenarbeitet. Bezüglich der Klemmwalze handelt es sich um eine ortsfest angeordnete, welche bspw. die Gegenwalzen der Zuführtisch-Elemente passiert und im Augenblick des Zusammenwirkens zur Festlegung des Verpackungswerkstoff-Endes dient. Auch ist noch hervorzuheben, dass die Schlaufe unterhalb des Zuführtisches gebildet wird. Dies geschieht infolge Schwerkraft, so dass weitere Bauteile zur Schaffung der Schlaufe nicht erforderlich sind. Alternativ kann die Vorrichtung zur Bildung des Halterungsteils eine Unterdruckeinrichtung aufweisen, die mit dem Teil des tischseitigen Halterungsteils zusammenwirkt. Eine weitere Lösung sieht ein Halterungsteil in Form einer Nagelleiste vor. Die Unterdruckeinrichtung ist zunächst stillstehend, woraufhin der zugeordnete Zuführtisch mit der darauf angeordneten Verpackungswerkstofflage unter der Unterdruckeinrichtung fortfährt, dies soweit, bis ein geeigneter Überstand zur Bildung des späteren Schlaufenendes gebildet ist. Die Unterdruckeinrichtung ist in Zuführrichtung verfahrbar angeordnet, zum synchronen Verfahren der Einrichtung mit dem Zuführtisch. Bevorzugt ist das Halterungsteil mit einer Schneideinrichtung kombiniert ausgebildet. Entsprechend sind Schneideinrichtung und Halterungsteil in einer weiteren Ausgestaltung zusammen in Zuführrichtung verfahrbar, dies weiter bevorzugt synchron zur Verlagerung des Zuführtisches. Als besonders vorteilhaft erweist sich eine Ausgestaltung, bei welcher der Zuführtisch eine quer zur Zuführrichtung verlaufende Schneidnut aufweist. Diese weist eine Breite von etwa 1 bis 10 mm, bevorzugt 5 mm auf. Das zuführbare Schneidmesser kann eingeschwenkt werden, so beispielsweise durch drehbewegliche Aufhängung desselben.In detail, the device has at least three movable feed table elements which each form a feed table and at least a part of the support part, which support part may be formed, for example, by a roller or roller or over the width of the feed table uniformly arranged roller sections. Alternatively, the support member may also be formed by a portion of the feed table itself. The feeder table elements are identical to each other and include at least a portion of the support member. In order to be able to carry out the connection process of the loop ends after closing the loop and moving the feed table into the subsequent position, a cutting device is provided. This separates the supplied packaging web at the specified location. For this purpose, the cutting device is provided in the conveying direction beyond the support member. The feeder table elements are associated with the device so that they can be moved cyclically. They take over another function, depending on the clock rate. They are preferably - when viewing a selected point of a feed table element - in a vertical plane cyclically movable. So also the condition can occur that one after moved down feed table element against the conveying direction is movable. However, this movement does not interfere with the operation of the device. Furthermore, the device is designed so that a downwardly moved feed table element in front of a packaging material supply roll is vertically movable in the upward direction. It then assumes the position of the feed table over which the packaging material is conveyed. Furthermore, a feed table element below the feed table may have a storage table. This is used in the appropriate position befindlichem feed table element of the convenient acceptance of the finished packaged long goods. To form the support part, the device has a pinch roller which cooperates with the part of the support part in the feed table element, for example with a counter-roller. So it is only a single pinch roller provided, which cooperates sequentially with the counter-rollers or parts of the support member of the feed table elements. With respect to the pinch roller is a stationary arranged, which, for example, passes the counter-rollers of the feed table elements and at the moment of interaction serves to fix the packaging material end. It should also be emphasized that the loop is formed below the feed table. This happens due to gravity, so that additional components to create the loop are not required. Alternatively, the device for forming the support member may include a vacuum device which cooperates with the part of the table-side support member. Another solution provides a support member in the form of a nail bar. The vacuum device is initially stationary, whereupon the associated feed table with the packaging material layer arranged thereon continues under the vacuum device, until a suitable projection for forming the later loop end is formed. The vacuum device is arranged to be movable in the feed direction for the synchronous operation of the device with the feed table. Preferably, the support member is formed combined with a cutting device. Correspondingly, cutting device and mounting part are movable together in a further embodiment in the feed direction, this further preferably synchronously with the displacement of the feed table. Particularly advantageous is an embodiment in which the feed table has a cutting groove running transversely to the feed direction. This has a width of about 1 to 10 mm, preferably 5 mm. The feedable cutting blade can be pivoted in, such as by the rotatable suspension of the same.

Die zur Durchführung des erfindungsgemäßen Verfahrens geeignete Vorrichtung ist als Ganzes mit der Ziffer 1 bezeichnet. Es liegt dabei eine schematische Darstellung vor. Einlaufseitig besitzt die Vorrichtung 1 zwei parallel zueinander angeordnete Wangen 2 zur Lagerung einer Verpackungswerkstoff-Vorratsrolle 3. Letztere beinhaltet einen Wickelkern 4, welcher zur nicht näher bezeichneten Lagerung der Vorratsrolle 3 dient. Anstelle einer Lagerung der Verpackungswerkstoff-Vorratsrolle 3 um ein ortsfestes Lager könnte auch ein tuchartiges Endloslager dienen, welches um entsprechende Rollen geführt ist, von denen zumindest eine angetrieben ist. Beim Ausführungsbeispiel handelt es sich bezüglich des Verpackungswerkstoffes um eine aus Kunststoff bestehende Folienbahn.The device suitable for carrying out the method according to the invention is designated as a whole by the number 1. There is a schematic representation. On the inlet side, the device 1 has two parallel arranged cheeks 2 for storing a packaging material supply roll 3. The latter includes a winding core 4, which is not closer designated storage of the supply roll 3 is used. Instead of a storage of the packaging material supply roll 3 to a stationary bearing could also serve a cloth-like endless bearing, which is guided around corresponding rollers, of which at least one is driven. In the embodiment, it is with respect to the packaging material to a plastic film web.

Der Verpackungswerkstoff-Vorratsrolle 3 sind zwei ein Walzenpaar bildende Rollen 5 und 6 von der Breite der Folienbahn nachgeordnet. Zumindest eine dieser Rollen 5, 6 ist in beiden Drehrichtungen antreibbar. Insbesondere die antreibende Rolle erstreckt sich walzenbildend über die gesamte Breite der Folienbahn, wobei bevorzugt eine Segmentierung vorgesehen ist, also eine Nebeneinanderanordnung mehrerer zueinander beabstandeter Rollen. Der Vorratsrolle 3 und den Rollen 5, 6 sind in einer Vertikalebene drei zyklisch verfahrbare Zuführtisch-Elemente I, II und III nachgeordnet. Letztere sind untereinander gleich gestaltet.The packaging material supply roll 3 are two rollers 5 and 6 forming a roller pair downstream of the width of the film web. At least one of these rollers 5, 6 can be driven in both directions of rotation. In particular, the driving roller extends roller-forming over the entire width of the film web, wherein preferably a segmentation is provided, ie a juxtaposition of a plurality of spaced rollers. The supply roll 3 and the rollers 5, 6 are arranged in a vertical plane three cyclically movable feed table elements I, II and III. The latter are identical to each other.

Im Einzelnen beinhaltet jedes Zuführtisch-Element ein Kastenprofil 7, dessen Länge der Breite der Folienbahn entspricht. Der Querschnitt des Kastenprofils 7 ist so gewählt, dass die Höhe desselben ein Mehrfaches der Breite ausmacht. An der in Förderrichtung der Verpackungsfolie 3' weisenden Längsseite bildet das Kastenprofil 7 Einschubleisten aus zur wahlweisen Anbringung eines Abnahmetisches 8. Letzterer ist im Wege eines Einschubes in verschiedenen Höhenlagen dem Kastenprofil 7 zuordbar. Die Länge des Abnahmetisches 8 entspricht ebenfalls der Länge des Kastenprofils 7.In detail, each feed table element includes a box section 7 whose length corresponds to the width of the film web. The cross section of the box profile 7 is chosen so that the height thereof is a multiple of the width. At the in the conveying direction of the packaging film 3 'facing longitudinal side, the box section 7 forms Einschubleisten for optional attachment of a take-off table 8. The latter is in the way of a drawer in different altitudes the box section 7 assignable. The length of the take-off table 8 also corresponds to the length of the box profile 7.

An seinem oberen Ende lagert das Kastenprofil 7 eine Gegenwalze 9, deren Länge derjenigen des Kastenprofils 7 und der Breite der Folienbahn 3 entspricht. Die Gegenwalze 9 ist bevorzugt über ihre Länge segmentiert, besteht demnach aus einer Nebeneinanderanordnung mehrerer zueinander beabstandeter Rollen oder Walzenabschnitten. Die Gegenwalze 9 durchgreift eine Öffnung 10 eines Zuführtisches 11, welcher in geeigneter Weise mit dem Kastenprofil 7 verbunden ist und eine Breite hat von der Breite der Folienbahn 3'. Die Gegenwalze 9 überragt daher geringfügig den Zuführtisch 11 und kann in Kontakt treten zu der von den Rollen 5, 6 in Förderrichtung x bewegten Folienbahn 3'. Wie aus den Zeichnungen ersichtlich ist, hat der Zuführtisch 11 in Förderrichtung x eine größere Länge als der Abnahmetisch 8. Alternativ kann der Abnahmetisch 8 auch gleich lang zum Zuführtisch 11 gebildet sein. Entsprechend stößt der Abnahmetisch 8 mit seinem freien Randbereich zumindest in der Fertigstellungsposition gegen den Rücken des Kastenprofils des vorgelagerten Zuführtisch-Elements.At its upper end, the box section 7 supports a counter-roller 9 whose length corresponds to that of the box section 7 and the width of the film web 3. The counter-roller 9 is preferably segmented over its length, consists Accordingly, from a juxtaposition of a plurality of spaced-apart rollers or roller sections. The counter-roller 9 passes through an opening 10 of a feed table 11, which is suitably connected to the box section 7 and has a width of the width of the film web 3 '. The counter-roller 9 therefore projects slightly beyond the feed table 11 and can come into contact with the film web 3 'moved by the rollers 5, 6 in the conveying direction x. As can be seen from the drawings, the feed table 11 has a greater length in the conveying direction x than the take-off table 8. Alternatively, the take-off table 8 can also be of equal length to the feed table 11. Accordingly, the take-off table 8 abuts with its free edge region, at least in the finishing position against the back of the box profile of the upstream feed table element.

Der Abnahmetisch 8 erstreckt sich zur Abstützung des Langgutes zumindest über die gesamte Breite der Folienbahn. Diesbezüglich ist bevorzugt, den Abnahmetisch 8 aus nebeneinander angeordneten, etwa gleichmäßig zueinander beanstandeten Abnahmezinken zu bilden.The take-off table 8 extends to support the long goods at least over the entire width of the film web. In this regard, it is preferable to form the take-off table 8 of side-by-side, approximately uniformly spaced apart picking tines.

Die Zuförderungsrichtung x des Verpackungswerkstoffes bzw. der Folienbahn 3' verläuft quer zur Längserstreckung eines Langgutes 12. Beim dargestellten Ausführungsbeispiel handelt es sich bezüglich des Langgutes 12 um aus einer Herstellungsmaschine kommender Extrusionsprofile mit einer Länge von mehr als 1 Meter. Diese Extrusionsprofile bzw. Langgüter gelangen nach dem Austreten aus der Herstellungsmaschine auf Stützrollen 13, welche an einem schwenkbaren Träger 14 angeordnet sind. In der Auflaufstellung des Langgutes 12 sind die Stützrollen 13 in einer horizontalen Ebene hintereinander angeordnet. Der Träger 14 vermag um eine Achse 15 des Maschinengestells in Uhrzeigerrichtung zu verschwenken, so dass dann das bzw. mehrere Langgüter von den Stützrollen 13 abgleiten.The feed direction x of the packaging material or the film web 3 'extends transversely to the longitudinal extension of a long good 12. In the illustrated embodiment, it is with respect to the long goods 12 coming from a manufacturing machine extrusion profiles with a length of more than 1 meter. After exiting the production machine, these extrusion profiles or long goods reach supporting rollers 13, which are arranged on a pivotable carrier 14. In the emergence position of the long goods 12, the support rollers 13 are arranged in a horizontal plane one behind the other. The carrier 14 is able to pivot about an axis 15 of the machine frame in the clockwise direction, so that then slide the or more long goods from the support rollers 13.

Die drei untereinander gleichen Zuführtisch-Elemente I, II und III können in der in den Figuren rechteckig veranschaulichten Umlaufbahn unterschiedliche Positionen A, B, C, D, E, und F einnehmen, und zwar während eines zyklischen Umlaufes. An der Position C befindet sich eine ortsfest gelagerte Klemmwalze 16 von der Breite der Folienbahn 3', welche im Zusammenwirken mit der ihr gegenüberliegenden Gegenwalze 9 des betreffenden Zuführtisch-Elementes ein Halterungsteil 17 bildet. Jenseits des Halterungsteils 17 ist in Förderungsrichtung x eine Schneidvorrichtung 18 vorgesehen. Diese kann ein Rollmesser oder ein Schneidmesser beinhalten. Das Widerlager für die Schneidvorrichtung 18 bildet der Zuführtisch 11 des jeweiligen Zuführhsch-Elementes I oder II oder III.The three feeder table elements I, II and III, which are identical to one another, can occupy different positions A, B, C, D, E, and F in the orbit, which is rectangular in the figures, during a cyclic circulation. At the position C there is a stationarily mounted pinch roller 16 of the width of the film web 3 ', which forms a support member 17 in cooperation with the counter-roller 9 of the respective feed table element opposite it. Beyond the support member 17, a cutting device 18 is provided in the conveying direction x. This may include a rolling knife or a cutting knife. The abutment for the cutting device 18 forms the feed table 11 of the respective Zuführhsch element I or II or III.

Es stellt sich folgende Wirkungsweise ein:The following mode of action occurs:

Gemäß der Ausgangsstellung nach Fig.1 befindet sich an der Position A das Zuführtisch-Element I. Die Position B ist unbesetzt. Die Position C wird von dem Zuführtisch-Element II eingenommen, während das Zuführtisch-Element III an der Position D liegt.According to the initial position according to FIG. 1, the feed table element I is located at the position A. The position B is unoccupied. The position C is occupied by the feed table element II while the feed table element III is at the position D.

Die Folienbahn 3' wird mittels der Rollen 5, 6 von der Vorratsrolle 3 abgezogen und überläuft den Zuführtisch 11 des an der Position A befindlichen Zuführtisch-Elementes I. Das Ende 3" der Folienbahn 3' gelangt in das Halterungsteil 17, welches von der Klemmwalze 16 und der Gegenwalze 9 gebildet wird. Aufgrund des weiteren Zulaufs des Verpackungswerkstoffes bzw. der Folienbahn 3' entsteht zwischen dem Zuführungstisch 11 des Zuführungstisch-Elementes I und dem Halterungsteil 17 eine nach unten durchhängende Schlaufe S. Nach Bildung einer ausreichend großen Schlaufe S beenden die Rollen 5, 6 die Zuführung der Folienbahn 3'. Einhergehend erhält der Träger 14 den Impuls mit den das Langgut 12 aufnehmenden Stützrollen 13 in Abwärtsrichtung zu schwenken, wobei das Langgut 12 von den Stützrollen 13 abgleitet und an die Schlaufe S übergeben wird. Es stellt sich hierdurch die Lage gemäß Fig. 2 ein. Aus dieser Figur 2 ist auch ersichtlich, dass das Zuführtisch-Element III über die Position E in die Position F gelaufen ist, also dann unterhalb des Zuführtisch-Elementes I liegt. Durch das Gewicht des Langgutes 12, welches als Extrusionsprofil ausgebildet ist, erfolgt ein V-förmiges Ausstülpen der Schlaufe S. Der nächste Verfahrensschritt besteht darin, dass das Zuführtisch-Element I in die Position B vorfährt, vgl. Fig. 3. Hierbei wird die Schlaufe S geschlossen, innerhalb welcher Schlaufe S mehrere Langgüter 12 in Nebeneinanderlage eingelegt worden sind. Bevor die Tischkante 11' das Halterungsteil 17 erreicht, laufen die Rollen 5, 6 entgegen Abzugsrichtung um und bewirken ein Zurückfördern der Folienbahn 3' bei gleichzeitiger Straffziehung im Schlaufenbereich. Hiernach setzt der Antrieb der Rollen 5, 6, aus, während die Tischkante 11' die Schlaufe S durch weiteres Vorfahren endgültig schließt und dabei in Klemmlage zum Halterungsteil 17 bzw. der dortigen Gegenwalze 9 tritt. Der zuvor im Bereich der Schlaufe S vorhandene, zwischen Zuführtisch 11 und Halterungsteil 17 sich erstreckende freilaufende Abschnitt ist nun vollständig geschlossen. Nach diesem Schließen fährt das Zuführtisch-Element I zusammen mit dem Zuführtisch-Element II in die Fertigstellungsposition D vor, vergleiche Figur 4. Im Zuge dieses Verfahrens in die Fertigstellungsposition D wird zugleich Verpackungsmaterial bzw. die Folienbahn 3' nachgezogen. Da nun auch die Rollen 5, 6 in Förderrichtung angetrieben sind, hat sich zwischen dem Zuführtisch-Element III, welches in die Position A in Aufwärtsrichtung verfahren ist, und dem Halterungsteil 17 erneut eine Schlaufe S gebildet. In der Stellung gemäß Figur 4 wird zwischen den Positionen C und D eine Abtrennung des Verpackungs-Werkstoffes bzw. der Folienbahn 3' mittels der Schneideinrichtung 18 vorgenommen. Das bereits vorhandene Schlaufenende 3" und das neu entstandene Schlaufenende 3''' treten gegeneinander, und mittels einer an der Position D befindlichen Schweißeinrichtung 19 erfolgt das Verbinden der Schlaufenenden 3" und 3''' durch Verschweißen. In dieser Position D kann auch ein Verschluss der Schlaufe an einer oder beiden Enden, die Stirnseiten des Langgutes 12 verschließend, vorgenommen werden.The film web 3 'is withdrawn from the supply roll 3 by means of the rollers 5, 6 and passes over the feed table 11 of the feed table element I located at the position A. The end 3 "of the film web 3' enters the holding part 17, which is from the pinch roll 16 and the counter-roller 9 is formed due to the further inflow of the packaging material or the film web 3 'between the feed table 11 of the feed table element I and the support member 17 is a sagging loop S. After forming a sufficiently large loop S terminate the Rolls 5, 6, the supply of the film web 3 '., In addition, the carrier 14 receives the pulse with the long goods 12 receiving support rollers 13 in the downward direction to pivot, the long goods 12 slides off the support rollers 13 and is passed to the loop S. This raises the situation according to FIG. 2. From this figure 2 it can also be seen that the feed table element III has run over the position E in the position F, that is then below the feed table element I. Due to the weight of the long material 12, which is designed as an extrusion profile, there is a V-shaped everting of the loop S. The next method step consists in that the feed table element I advances to the position B, cf. Fig. 3. Here, the loop S is closed, within which loop S several long goods 12 have been inserted in juxtaposition. Before the table edge 11 'reaches the support member 17, the rollers 5, 6 run counter to the withdrawal direction and cause the film web 3' to be conveyed back together with simultaneous tensioning in the loop area. Thereafter, the drive of the rollers 5, 6, from sets, while the table edge 11 ', the loop S by further ancestor finally closes and thereby enters the clamping position to the support member 17 and the local counter-roller 9. The previously existing in the loop S between feed table 11 and support member 17 extending free-running portion is now completely closed. After this closing, the feed table element I moves together with the feed table element II into the finishing position D, compare FIG. 4. In the course of this method, into the finishing position D, the packaging material or the film web 3 'is simultaneously drawn. Since now the rollers 5, 6 are driven in the conveying direction, a loop S has again formed between the feed table element III, which is moved in the position A in the upward direction, and the support member 17. In the position according to FIG. 4, a separation of the packaging material or the film web 3 'is carried out between the positions C and D by means of the cutting device 18. The already existing loop end 3 "and the newly formed loop end 3 '''occur against each other, and by means of a located at the position D welding device 19, the joining of the loop ends In this position D, a closure of the loop at one or both ends, the end faces of the long goods 12 closing, made.

Der nächste Verfahrensschritt ist aus Fig. 5 ersichtlich. Das Zuftihrtisch-Element II ist in Abwärtsrichtung gefahren und nimmt die Position E ein. Ferner hat die Schweißvorrichtung 19 die miteinander verbundenen Schlaufenenden 3" und 3''' freigegeben, so dass nun das verpackte Langgut auf den Abnahmetisch 8 des Zuführtisch-Elementes I aufsetzen kann. Von hier aus erfolgt das Abnehmen des verpackten Langgutes 12. Gleichzeitig mit diesem Vorgang ist bereits ein neues Langgut in die neu gebildete Schlaufe S eingelegt worden, so dass ein erneuter Verfahrenszyklus stattfinden kann. Hierzu sei erwähnt, dass das neu entstandene Schlaufenende 3" bei Einlegen des Langgutes 12 in die Schlaufe um ein geringes Maß zurückgefördert wurde, so dass das vorliegende Schlaufenende 3" die Länge wie beim ersten Zyklus besitzt. Im weiteren Verfahrensablauf schließt nach Auffüllen der Schlaufe S das Zuführtisch-Element III die Schlaufe, so dass dann an die Stelle des Zuführtisch-Elementes III das Zuführtisch-Element II treten kann. So übernehmen die Zuführtisch-Elemente bei diesem zyklischen Verfahren der Elemente unterschiedliche Funktionen.The next process step is shown in FIG. 5. The Züfihrtisch element II has moved in the downward direction and assumes the position E. Furthermore, the welding device 19 has the interconnected loop ends 3 "and 3 '' 'released, so that now the packaged long goods can put on the take-off table 8 of the feed table element I. From here, the removal of the packaged long goods 12 takes place simultaneously with this A new long product has already been inserted into the newly formed loop S, so that a new cycle of processing can take place.For this it should be mentioned that the newly formed loop end 3 "was fed back by a small amount when inserting the long product 12 into the loop, then In the further procedure, after filling in the loop S, the feed table element III closes the loop so that the feed table element II can then take the place of the feed table element III. Thus, the feed table elements assume different functions in this cyclic process of the elements NEN.

Die Darstellungen in den Figuren 6 bis 11 zeigen eine zweite Ausführungsform der Vorrichtung 1. Diese entspricht in weiten Teilen der Vorrichtung 1 der ersten Ausführungsform, infolgedessen gleiche Bauteile bzw. Baugruppen gleiche Bezugsziffern tragen.The illustrations in FIGS. 6 to 11 show a second embodiment of the device 1. This corresponds in large part to the device 1 of the first embodiment, as a result of which identical components or assemblies carry the same reference numerals.

In dieser zweiten Ausführungsform ist das Halterungsteil 17 in Form einer Unterdruckeinrichtung 16' ausgebildet, welche mit einer tischseitigen Gegenwalze 9 wie im ersten Ausführungsbeispiel zusammenwirken kann. Bevorzugt wirkt die Unterdruckeinrichtung 16' direkt mit dem zugeordneten Zuführtisch 11 zusammen, so mit einem randseitigen Teil 9 des Tisches 11.In this second embodiment, the support member 17 in the form of a vacuum device 16 'is formed, which can cooperate with a table-side counter-roller 9 as in the first embodiment. Preferably acts the vacuum device 16 'directly with the associated feed table 11 together, so with a peripheral part 9 of the table eleventh

Die Schneidvorrichtung 18 ist mit dem Halterungsteil 17 kombiniert und entsprechend in unmittelbarer Nachbarschaft zu diesem positioniert. Wie in den Darstellungen zu erkennen, ist die Schneidvorrichtung 18 in Zuführrichtung x der Unterdruckeinrichtung 16' bzw. dem Halterungsteil 17 nachgeordnet.The cutting device 18 is combined with the support member 17 and positioned accordingly in the immediate vicinity of this. As can be seen in the illustrations, the cutting device 18 in the feed direction x of the vacuum device 16 'and the support member 17 downstream.

Wie weiter insbesondere aus der perspektivischen Detaildarstellung in Fig.11 zu erkennen, weist die Schneidvorrichtung 18 ein Messer 21 auf, welches um eine Achse y drehbeweglich aufgehängt ist und zur Durchführung des Schneidvorganges in Richtung auf den Zuführtisch 11 geschwenkt wird. Die Schwenkstellungen werden erreicht durch Über- bzw. Unterlaufen von Auflauf- (24) bzw. Ablaufschrägen (25), die endseitig des Halterungsteils 17 ausgebildet sind, wobei die erzwungene Schwenkstellung des Messers 21 bspw. durch eine nicht näher dargestellte Rastkugel-Sicherung (26) auslösbar verrastet ist. Das Messer 21 fährt hierbei in eine quer zur Zuführrichtung x verlaufende Schneidnut 20 im Zuführtisch 11 ein. Weiter ist das Messer 21 an einem vom Halterungsteil 17 abragenden Halterungsarm 23 angelenkt derart, dass ein Abschwenken der Messerschneide in die Nut 20 etwa in Zuführrichtung x erreichbar ist. Der Schneidvorgang wird erreicht durch Verlagerung der Schneidvorrichtung 18 quer zur Zuführrichtung x entlang des eine Führung 22 ausformenden Halterungsteils 17. Halterungsteil 17 und die hieran bevorzugt ausgebildete Führung 22 für die verlagerbare Schneidvorrichtung 18 sind in ihrer Erstreckung angepaßt an die Breite des zu verarbeitenden Verpackungswerkstoffes.As can further be seen in particular from the detailed perspective view in FIG. 11, the cutting device 18 has a knife 21 which is suspended in a rotary movement about an axis y and is pivoted in the direction of the feed table 11 for carrying out the cutting process. The pivoting positions are achieved by overflowing or underflowing casserole (24) or drainage slopes (25), which are formed on the end side of the holding part 17, wherein the forced pivoting position of the blade 21, for example. By a detent ball fuse (26 ) is releasably locked. The knife 21 moves in this case in a transverse to the feed direction x cutting groove 20 in the feed table 11 a. Next, the knife 21 is hinged to a protruding from the support member 17 support arm 23 such that a pivoting of the knife edge in the groove 20 is approximately reached in the feed direction x. The cutting operation is achieved by displacement of the cutting device 18 transversely to the feed direction x along the guide 22 forming a support member 17. Support member 17 and the preferred trained guide 22 for the displaceable cutting device 18 are adapted in their extension to the width of the packaging material to be processed.

Die Wirkungsweise der Vorrichtung 1 gemäß der zweiten Ausführungsform entspricht zunächst im Wesentlichen der des anhand der Figuren 1 bis 5 beschriebenen ersten Ausführungsbeispieles. So wird auch hier die Folienbahn 3' mittels der Rollen 5, 6 von der Vorratsrolle 3 abgezogen, wonach die Folienbahn 3' den Zuführtisch 11 des an der Position A befindlichen Zuführtisch-Elements I überläuft. Das Ende 3" der Folienbahn 3' gelangt in das Halterungsteil 17, welches mittels der vorgesehenen Unterdruckeinrichtung 16' das Folienbahnende 3" in Zusammenwirkung mit dem tischseitigen Abschnitt 9 fixiert. Aufgrund des weiteren Zulaufs des Verpackungswerkstoffes bzw. der Folienbahn 3' entsteht zwischen dem Zuführtisch 11 des Zuführtisch-Elements I und dem Halterungsteil 17 eine nach unten durchhängende Schlaufe S, in welche das Langgut 12 übergeben wird. Es stellt sich hierdurch die Lage gemäß Figur 7 ein. Im nächsten Verfahrensschritt fährt das Zuführtisch-Element I in die Position B vor (vgl. Figur 8). Hierbei wird die Schlaufe S geschlossen. Zur Straffung des Schlaufenbereichs laufen die Rollen 5, 6 bevor die Tischkante 11' das Halterungsteil 17 erreicht, entgegen Abzugsrichtung um und bewirken somit ein Zurückfördern der Folienbahn 3'. Hiernach setzt der Antrieb der Rollen 5, 6 aus, während die Tischkante 11' die Schlaufe S durch weiteres Vorfahren endgültig schliesst und dabei in Klemmlage zum Halterungsteil 17 tritt. Die Schlaufe S ist nunmehr vollständig geschlossen. Nach diesem Schliessen fährt das Zuführtisch-Element I zusammen mit dem Zuführtisch-Element II in Richtung auf die Fertigstellungsposition D vor, wobei zunächst das Halterungsteil 17 mitsamt der Schneidvorrichtung 18 vom Zuführtisch 11 des Zuführtisch-Elements II und teilweise vom Zuführtisch 11 des Zuführtisch-Elements I unterlaufen wird, soweit, bis ein geeigneter Überstand der auf dem Zuführtisch 11 aufliegenden Folienbahn 3' erreicht ist, welches Überstandsmaß zwischen dem nunmehr zum Halterungsteil 17 beabstandeten Tischabschnitt 9 und der Schneidvorrichtung 18 etwa dem freien Auslippmaß des freizuschneidenden Schlaufenendes 3''' entspricht (vgl. Fig. 9). Diese Stellung ist erreicht, wenn die Schneidnut 20 des nachfolgenden Zuführtisches 11 des Zuführtisch-Elements I die durch das Schneidmesser 21 definierte Schneidebene erreicht hat. Hiernach wird die Kombination aus Schneidvorrichtung 18 und Halterungsteil 17 zusammen mit den Zuführtisch-Elementen I und II in Zuführungsrichtung x verlagert soweit, bis das Zuführtisch-Element II die Fertigstellungsposition D erreicht hat. Im Zuge dieser Verlagerung des Halterungsteiles 17 samt der Schneidvorrichtung 18 kommt die Unterdruckeinrichtung 16' zur Wirkung; zieht demnach Material von der Vorratsrolle 3 nach. Nach Erreichen der Fertigstellungsposition D erfolgt die Abtrennung des Verpackungswerkstoffes bzw. der Folienbahn 3' mittels der Schneidvorrichtung 18. Das bereits vorhandene Schlaufenende 3" und das neu entstandene Schlaufenende 3"' treten gegeneinander, was weiter noch durch einen nicht dargestellten Anhebelfinger der Schweissvorrichtung 19 unterstützt sein kann. Mittels der Schweisseinrichtung 19 erfolgt das Verbinden der Schlaufenenden 3" und 3"' durch Verschweissen. Bevor, wie anhand des ersten Ausführungsbeispiels erläutert, das Zuführtisch-Element II in Abwärtsrichtung gefahren wird, verfährt die Kombination aus Halterungsteil 17 und Schneidvorrichtung 18 wieder zurück in die Anfangsposition C, dies bei anhaltender Unterdruckbeaufschlagung des freien Endes der Folienbahn 3'. Hierdurch wird ein erster Teil der Schlaufe S für die nächste Verpackung ausgebildet. Der weitere Verfahrensablauf entspricht dem des ersten Ausführungsbeispieles.The mode of operation of the device 1 according to the second embodiment initially corresponds essentially to that described with reference to FIGS. 1 to 5 first embodiment. Thus, here too, the film web 3 'is withdrawn from the supply roll 3 by means of the rollers 5, 6, after which the film web 3' overflows the feed table 11 of the feed table element I located at the position A. The end 3 "of the film web 3 'passes into the holder part 17, which fixes the film web end 3" in cooperation with the table-side section 9 by means of the intended vacuum device 16'. Due to the further inflow of the packaging material or the film web 3 'is formed between the feed table 11 of the feed table element I and the support member 17 down a sagging loop S, in which the long goods 12 is transferred. As a result, the position according to FIG. 7 is established. In the next method step, the feed table element I moves to the position B (see FIG. Here, the loop S is closed. To streamline the loop area, the rollers 5, 6 run before the table edge 11 'reaches the holding part 17, in the opposite direction to the withdrawal direction and thus bring about a return conveyance of the film web 3'. Thereafter, the drive of the rollers 5, 6 sets off, while the table edge 11 ', the loop S finally closes by another ancestor, while in clamping position to the support member 17 occurs. The loop S is now completely closed. After this closing, the feed table element I moves together with the feed table element II in the direction of the finishing position D, wherein first the holding part 17 together with the cutting device 18 from the feed table 11 of the feed table element II and partly from the feed table 11 of the feed table element I is underrun, as far as until a suitable supernatant of lying on the feed table 11 film web 3 'is reached, which supernatant between the distance now to the support member 17 spaced table portion 9 and the cutting device 18 about the free Auslippmaß of freely cut loop end 3''' corresponds ( see Fig. 9). This position is reached when the cutting groove 20 of the subsequent feed table 11 of the feed table element I has reached the cutting plane defined by the cutting blade 21. After that, the Combination of cutting device 18 and support member 17 together with the feed table elements I and II displaced in the feed direction x until the feed table element II has reached the completion position D. In the course of this displacement of the support member 17 together with the cutting device 18, the vacuum device 16 'comes into effect; accordingly draws material from the supply roll 3. After reaching the finishing position D, the separation of the packaging material or the film web 3 'by means of the cutting device 18. The already existing loop end 3 "and the newly formed loop end 3"' compete against each other, which further supported by a not shown Anhebelfinger the welding device 19 can be. By means of the welding device 19, the connecting of the loop ends 3 "and 3"'by welding takes place. Before, as explained with reference to the first embodiment, the feed table element II is driven in the downward direction, moves the combination of support member 17 and cutting device 18 back to the initial position C, this with continued negative pressure of the free end of the film web 3 '. As a result, a first part of the loop S is formed for the next package. The further procedure corresponds to that of the first embodiment.

Wie weiter aus den Darstellungen zu erkennen, erstreckt sich der Abnahmetisch 8 unterseitig des zugeordneten Kastenprofils 7, dies bei einer in Zuführrichtung x gemessenen Länge, die größer ist als die Länge des Zuführtisches 11. Entsprechend unterfängt der Abnahmetisch 8 mit seinem freien Ende insbesondere in der Fertigstellungsposition das Kastenprofil 7 des vorgeordneten Zuführtisch-Elements II.As can be further seen from the illustrations, the take-off table 8 extends below the associated box section 7, this at a measured length in the feed direction x, which is greater than the length of the feed table 11. Accordingly, the take-off table 8 undercuts with its free end, in particular in the Completion position the box section 7 of the upstream feed table element II.

Das Zuführtisch-Element II verfährt nach Ablegen des verpackten Langgutes 12 auf den Abnahmetisch 8 des Zuführtisch-Elements I zunächst weiter in Zuführrichtung x, um nach Verlassen des Überstandabschnitts des Abnahmetisches 8 in Abwärtsrichtung zu fahren.After the packaged long goods 12 have been deposited, the feed table element II first moves on to the take-off table 8 of the feed table element I in the feed direction x, to go after leaving the supernatant portion of the take-off table 8 in the downward direction.

Der Abnahmetisch 8 ist in diesem Ausführungsbeispiel über die in Breitenrichtung der Folienbahn gemessene Länge segmentiert. Zwischen zwei zueinander beanstandeten Abnahmezinken 8' ergibt sich ein Freiraum, über welchen sich das abgelegte Langgut 12 erstreckt. Zum Abtransport des Langguts 12 ist eine Transferwalze 27 vorgesehen, die auf ihrem Mantel radial abragende Mitnahmestäbe 28 aufweist. Letztere sind bei einer Ausrichtung der Walzenachse z quer zur Förderrichtung x entsprechend der Ausbildung des Ablagetisches 8 bzw. der segmentierten Ablagezinken 8' auf Lücke angeordnet, greifen demnach in den zwischen zwei benachbarten Ablagezinken 8' belassenen Freiraum. Die Transferwalze wird zur Übergabe des Langguts 12 in Rotation versetzt, wobei die Mitnahmestäbe 28 von unten durch die Freiräume des Ablagetisches 8 treten und das Langgut 12 tragend auf der gegenüberliegenden Seite zum weiteren Transport auf einen gleichfalls segmentierten Übergabetisch 29 ablegen. Dieser Übergabetisch 29 kann - wie abgebildet - geneigt ausgerichtet, weiter bspw. in Form eines Rollentisches ausgebildet sein. Über den Umfang der Transferwalze 27 sind gleichmäßig zueinander beabstandet mehrere Mitnahmestäbe 28 vorgesehen.The take-off table 8 is segmented in this embodiment over the length measured in the width direction of the film web length. Between two mutually offending acceptance tines 8 'results in a free space over which the stored long goods 12 extends. For the removal of the long goods 12, a transfer roller 27 is provided which has radially projecting driving rods 28 on its jacket. The latter are arranged with an alignment of the roll axis z transversely to the conveying direction x corresponding to the formation of the tray table 8 and the segmented storage tines 8 'on gap, thus engage in between two adjacent storage tines 8' left clearance. The transfer roller 12 is set into rotation for the transfer of the long goods 12, whereby the driving rods 28 pass from below through the clearances of the delivery table 8 and deposit the long goods 12 on the opposite side for further transport on an equally segmented transfer table 29. This transfer table 29 can - as shown - inclined aligned, further example, be formed in the form of a roller table. Over the circumference of the transfer roller 27 a plurality of driving rods 28 are uniformly spaced from each other.

Anstelle einer Kunststofffolie oder Papierbahn könnte auch ein anderer Verpackungswerkstoff zum Einsatz gelangen. Beispielsweise wäre es möglich, Textilbahnen zu verwenden. Gegebenenfalls wäre sogar der Einsatz von Metallfolien denkbar, wobei das Verbinden der Schlaufenenden jeweils in der entsprechenden Weise zu geschehen hätte.Instead of a plastic film or paper web, another packaging material could also be used. For example, it would be possible to use textile webs. Optionally, even the use of metal foils would be conceivable, wherein the connecting of the loop ends would have to be done in each case in the appropriate manner.
