Abstract

The group of objects are supplied on a conveyor (1) to a packing station (9) where the wrapping material (4) is unwound from a reel and divided into a strip (7) forming the packet tray and a strip (8) for wrapping round the top. These two strips are supplied jointly vertically to the packing station forming a distance gap (13) corresponding to the height of the goods. The group of goods is moved across the strips and onto a discharge conveyor (2) whereby the strips loop U-shaped around the goods leaving overhangs (14,15) at the back which are separated from the incoming strips. The ends of the tray and top strips are connected together at the ends of the overhangs. The areas of the strips protruding over the base edge (16) of the packet are folded and fixed to a tray edge or tray base. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zum Anlegen einer aus bandförmigem Verpackungsmaterial, welches von einem Coil abgezogen wird, aufgebauten Verpackung an eine Mehrzahl von gleichen, Packgutelementen, die zu einer Packgutgesamtheit zusammengefügt sind. Es versteht sich, daß die Packgutgesamtheit eine kubische Gestaltung aufweist, die sich aus dem Zusammenfügen der Packgutelemente ergibt. Die Packgutelemente können z.B. kubische Packgutelemente oder zylindrische Packgutelemente sein.The invention relates to a method for applying a packaging constructed from band-shaped packaging material, which is drawn off from a coil, to a plurality of the same, packaged goods elements, which are combined to form a packaged goods assembly. It goes without saying that the packaged goods as a whole have a cubic design, which results from the assembly of the packaged goods elements. The packaged goods elements can e.g. be cubic packaged goods or cylindrical packaged goods.

Im Rahmen der bekannten Maßnahmen, von denen die Erfindung ausgeht (EP 0 313 721 A2), werden aus dem bandförmigen Verpackungsmaterial Verpackungsstäbe geformt, die an die Kanten und Ecken der Packgutgesamtheit angelegt und zu einem Rahmentragwerk zusammengesetzt werden. Das hat sich bewährt, verlangt aber ein entsprechendes steifes Verpackungsmaterial, welches die beschriebene Stab- und Rahmenfunktion erfüllen kann. Das ist aufwendig. Im übrigen weisen aus einer vorgegebenen Mehrzahl von kubischen Packgutelementen aufgebaute Packgutgesamtheiten nicht unbeachtliche Toleranzen auf, die sich in der Breite und in der Länge bzw. in der Höhe zu Toleranzen von 10 bis 20 mm addieren können. Werden die Stäbe und das Rahmentragwerk nach Maßgabe der maximal auftretenden Toleranzen dimensioniert, so kann die so aufgebaute Verpackung die Packgutgesamtheit nicht als Straffverpackung umgeben. Andererseits kann eine Straffverpackung Packgutgesamheiten, die aus einer Mehrzahl von Packgutelementen aufgebaut sind, so verspannen, daß über Reibungsschluß zwischen den Packgutelementen gleichsam ein selbsttragender Effekt in der Packgutgesamtheit zustandekommt.Within the framework of the known measures from which the invention is based (EP 0 313 721 A2), packaging rods are formed from the band-shaped packaging material, which are placed against the edges and corners of the packaged goods and assembled to form a framework. This has proven itself, but requires a corresponding stiff packaging material that can fulfill the rod and frame function described. It is expensive. Otherwise, packaged goods assemblies composed of a predetermined number of cubic packaged goods elements do not have negligible tolerances, which can add up to tolerances of 10 to 20 mm in width and length or in height. If the bars and the framework are dimensioned according to the maximum tolerances, the packaging constructed in this way cannot surround the packaged goods as tight packaging. On the other hand, a tight package can brace packaged goods that are made up of a plurality of packaged goods elements so that a frictional connection between the packaged goods elements creates a self-supporting effect in the packaged goods as a whole.

Grundsätzlich ist es bekannt (DE 40 27 762 C1), zur Herstellung einer Verpackung für stückiges Packgut, die aus einem Rahmentragwerk aus winkelförmigen Elementen aus Verpackungsmaterial mit zumindest einem offenen Rahmenfeld aufgebaut ist und bei der ein Streifen aus dem Verpackungsmaterial an das Packgut angelegt und der an dem Packgut anliegende Streifen zu einer Umreifung geschlossen wird, den Streifen als ebenen Materialstreifen von einem Coil abzuziehen, straff mit überstehendem Rand an das Packgut anzulegen und erst am Packgut winkelförmig umzufalten, wobei überlappende Endabschnitte miteinander verbunden werden. Das hat sich bewährt und erlaubt den Aufbau einer Straffverpackung, bei der die beschriebenen Toleranzprobleme nicht auftreten, und die es erlaubt, mit einem wenig steifen Verpackungsmaterial, beispielsweise in Form von sogenanntem Kraftpapier, zu arbeiten. Im Rahmen dieser Maßnahmen ist es auch bekannt, sowohl an der Kopfseite als auch an der Bodenseite des Packgutes Umreifungen aus streifenförmigem Verpackungsmaterial mit überstehendem Rand herzustellen.Basically, it is known (DE 40 27 762 C1) for the production of packaging for lumpy packaged goods, which is constructed from a frame structure made of angular elements made of packaging material with at least one open frame field and in which a strip of packaging material is applied to the packaged goods and the strips lying on the packaged goods are closed to form a strapping, pull the strips off a coil as a flat strip of material, place them tightly with a protruding edge on the packaged goods and only fold over them angularly on the packaged goods, overlapping end sections being connected to one another. This has proven itself and allows the construction of a tight package, in which the tolerance problems described do not occur, and which makes it possible to work with a less rigid packaging material, for example in the form of so-called kraft paper. Within the scope of these measures, it is also known to produce strapping from strip-shaped packaging material with a protruding edge both on the head side and on the bottom side of the packaged goods.

Ausgehend von den zuletzt beschriebenen Maßnahmen liegt der Erfindung das technologische Problem zugrunde, auf besonders einfache Weise eine aus bandförmigem Verpackungsmaterial, welches von einem Coil abgezogen wird, aufgebaute Verpackung an eine Mehrzahl von gleichen Packgutelementen, die zu einer Packgutgesamtheit zusammengefügt sind, anzulegen.On the basis of the measures described lastly, the invention is based on the technological problem of applying packaging constructed from tape-shaped packaging material which is pulled off a coil in a particularly simple manner to a plurality of identical packaged goods elements which are combined to form a packaged goods assembly.

Zur Lösung dieser Aufgabe ist Gegenstand der Erfindung ein Verfahren zum Anlegen einer aus bandförmigem Verpackungsmaterial, welches von einem Coil abgezogen wird, aufgebauten Verpackung an eine Mehrzahl von gleichen Verpackungselementen, die zu einer Packgutgesamtheit zusammengefügt sind, mit den Verfahrensschritten:

  • a) Die Packgutgesamtheit wird auf einem Zuführförderer einer Verpackungsstation zugeführt,
  • b) das Verpackungsmaterial wird von dem Coil abgezogen und beim Abziehen zumindest in einen traybildenden Verpackungsmaterialstreifen sowie einen Kopfumreifungsstreifen aufgetrennt,
  • c) der traybildende Verpackungsmaterialstreifen sowie der Kopfumreifungsstreifen werden gemeinsam unter Bildung eines Abstandsspaltes, der der Höhe der Packgutgesamtheit angepaßt ist, vertikal der Verpackungsstation zugeführt und entsprechend dem Produktformat vorgespendet,
  • d) die Packgutgesamtheit wird mit einer vorderen Stirnseite voraus an der Verpackungsstation quer zu dem traybildenden Verpackungsmaterialstreifen und dem Kopfumreifungsstreifen so verschoben und auf einen Abführförderer aufgeschoben, daß der Verpackungsmaterialstreifen sowie der Kopfumreifungsstreifen die Packgutgesamtheit U-förmig umschlingen und an der rückwärtigen Stirnseite Überstände des traybildenden Verpackungsmaterialstreifens sowie des Kopfumreifungsstreifens, die von den zulaufenden Streifen abgetrennt werden, frei bleiben,
  • e) die Enden des traybildenden Verpackungsmaterialstreifens sowie die des Kopfumreifungsstreifens werden mit den Enden der Überstände zu Umreifungen miteinander verbunden,
  • f) die über den Bodenrand der Packungsgesamtheit überstehenden Bereiche des traybildenden Verpackungsmaterialstreifens werden zu einem Trayrand oder zu einem Trayboden umgefaltet und fixiert,
wobei die Verfahrensschritte d), e) und f) an der auf dem Abführförderer aufliegenden Packungsgesamtheit durchgeführt werden. Die traybildenden Verpackungsmaterialstreifen sowie die Kopfumreifungsstreifen werden nach bevorzugter Ausführungsform der Erfindung zu unter Zugspannung stehenden Straffumreifungen verbunden. Im Rahmen des erfindungsgemäßen Verfahrens werden nach bevorzugter Ausführungsform der Zuführförderer und der Abführförderer kontinuierlich bewegt. Im Rahmen der Erfindung liegt es aber auch, den Zuführförderer und den Abführförderer taktweise zu bewegen, selbstverständlich unter Abstimmung der Takte. In dem Merkmal b) kommt mit der Formulierung "zumindest in einen traybildenden Verpackungsmaterialstreifen sowie einen Kopfumreifungsstreifen" zum Ausdruck, daß z.B. nach Maßgabe der Höhe der Verpackungsgutgesamtheit auch ein dritter Verpackungsmaterialstreifen ausgetrennt werden kann. Er kann zu einer mittleren Straffumreifung an die Verpackungsgutgesamtheit gelegt werden, wobei so verfahren wird, wie es in bezug auf den traybildenden Verpackungsmaterialstreifen und in bezug auf den Kopfstreifen beschrieben wurde. Insbesondere kann so verfahren werden, daß der traybildende Verpackungsmaterialstreifen im Bereich seines oberen Randes, der an den Seitenwänden der Verpackungsgutgesamtheit anliegt, mit einem Verstärkungsstreifen versehen wird.To achieve this object, the subject of the invention is a method for applying a packaging constructed from band-shaped packaging material which is drawn off from a coil to a plurality of identical packaging elements which are combined to form a packaged product, with the method steps:
  • a) the packaged goods are fed to a packaging station on a feed conveyor,
  • b) the packaging material is pulled off the coil and, when pulled off, is at least separated into a tray-forming packaging material strip and a head strapping strip,
  • c) the tray-forming packaging material strip and the head strapping strip are jointly fed vertically to the packaging station, forming a spacing gap which is adapted to the height of the packaged goods, and pre-dispensed in accordance with the product format,
  • d) The packaged goods are moved with a front end face ahead at the packaging station transversely to the tray-forming packaging material strip and the head strapping strip and pushed onto a discharge conveyor in such a way that the packaging material strip and the head strapping strip wrap around the packaged goods set in a U-shape and protrusions of the tray-forming packaging material strip on the rear end face and the head strapping, which are separated from the incoming strips, remain free,
  • e) the ends of the tray-forming packaging material strip and that of the head strapping are connected to one another with the ends of the protrusions to form strapping,
  • f) the areas of the tray-forming packaging material strip that protrude beyond the bottom edge of the pack assembly are folded over and fixed into a tray edge or tray bottom,
the process steps d), e) and f) are carried out on the pack assembly lying on the discharge conveyor. According to a preferred embodiment of the invention, the tray-forming packaging material strips and the head strapping strips are connected to tension straps which are under tension. In the context of the method according to the invention, the feed conveyor and the discharge conveyor are moved continuously according to a preferred embodiment. However, it is also within the scope of the invention to move the feed conveyor and the discharge conveyor in cycles, of course with coordination of the cycles. In the feature b), the expression "at least in a tray-forming packaging material strip and a head strapping strip" expresses the fact that, for example, a third packaging material strip can also be cut out in accordance with the height of the packaged goods. It can be applied to the packaged goods as a medium tight strapping, following the procedure described for the tray-forming packaging material strip and for the head strip. In particular, the procedure can be such that the tray-forming strip of packaging material is provided with a reinforcing strip in the region of its upper edge which lies against the side walls of the packaged goods.

Die Erfindung geht von der Erkenntnis aus, daß eine aus bandförmigem Verpackungsmaterial, welches von einem Coil abgezogen wird, aufgebaute Verpackung an einer Mehrzahl von gleichen Packgutelementen, die zu einer Packgutgesamtheit zusammengefügt sind, besonders einfach erzeugt werden kann, wenn die Kombination der beschriebenen Maßnahmen verwirklicht wird, die es erlaubt, die Packgutgesamtheit mit einer vorderen Stirnseite an der Verpackungsstation quer zu dem traybildenden Verpackungsmaterialstreifen und dem Kopfumreifungsstreifen in der beschriebenen Weise zu verschieben. Auf diese Weise kann mit kurzen Packzeiten gearbeitet werden, auch bleibt in der Verpackungsstation ausreichend Raum, um die entsprechenden Werkzeuge anzubringen. Im Ergebnis kann eine Vorrichtung für die Durchführung des erfindungsgemäßen Verfahrens besonders einfach gestaltet werden.The invention is based on the knowledge that a packaging constructed from band-shaped packaging material which is drawn off from a coil can be produced in a particularly simple manner on a plurality of identical packaged goods elements which are combined to form a packaged goods package if the combination of the measures described is implemented which allows the packaged goods to be moved with a front end face at the packaging station transversely to the tray-forming packaging material strip and the head strapping strip in the manner described. In this way you can work with short packing times, and there is also enough space in the packaging station to attach the appropriate tools. As a result, a device for carrying out the method according to the invention can be designed to be particularly simple.

Gegenstand der Erfindung ist auch eine Vorrichtung für die Durchführung des beschriebenen Verfahrens mit einem Zuführförderer, einem rechtwinklig dazu angeordneten Abführförderer, einer oberhalb des Niveaus des Zuführförderers und des Abführförderers angeordneten Coilaufnahme für das bandförmige Verpackungsmaterial mit Bandabzug und Trenneinrichtung zur Auftrennung des bandförmigen Verpackungsmaterials in einen traybildenden Verpackungsmaterialstreifen und einen Kopfumreifungsstreifen, wobei der traybildende Verpackungsmaterialstreifen und der Kopfumreifungsstreifen gemeinsam unter Bildung eines Abstandsspaltes vertikal verlaufend zwischen dem Zuführförderer und dem Kopf des Abführförderers geführt sind und in diesem Bereich die Verpackungsstation mit ihren Werkzeugen zur Durchführung der Verfahrensschritte (d), (e) und (f) angeordnet ist.The invention also relates to a device for carrying out the described method with a feed conveyor, a discharge conveyor arranged at right angles thereto, a coil holder for the band-shaped packaging material with a strip take-off and a separating device for separating the band-shaped packaging material into a tray-forming unit, arranged above the level of the feed conveyor and the discharge conveyor Packaging material strip and a head strapping strip, the tray-forming packaging material strip and the head strapping strip being guided together vertically to form a spacing gap between the feed conveyor and the head of the discharge conveyor, and in this area the packaging station with its tools for carrying out process steps (d), (e) and (f) is arranged.

Die in den Fig. 1 und 2 dargestellte Vorrichtung für die Durchführung des erfindungsgemäßen Verfahrens besteht in ihrem grundsätzlichen Aufbau aus einem Zuführförderer 1, einem rechtwinklig dazu angeordneten Abführförderer 2, einer oberhalb des Niveaus des Zuführförderers 1 und des Abführförderers 2 angeordneten Coilaufnahme 3 für das bandförmige Verpackungsmaterial 4 mit Bandabzug 5 und Trenneinrichtung 6 zur Auftrennung des bandförmigen Verpackungsmaterials 4 in einen traybildenden Verpackungsmaterialstreifen 7 und einen Kopfumreifungsstreifen 8. Man erkennt, daß der traybildende Verpackungsmaterialstreifen 7 sowie der Kopfumreifungsstreifen 8 vertikal verlaufend zwischen dem Zuführförderer 1 und dem Kopf des Abführförderers 2 geführt sind. In diesem Bereich ist die Verpackungsstation 9 mit ihren üblichen Werkzeugen angeordnet, die nicht gezeichnet sind.1 and 2 for the implementation of the method according to the invention consists in its basic structure of a feed conveyor 1, a discharge conveyor 2 arranged at right angles thereto, a coil holder 3 arranged above the level of the feed conveyor 1 and the discharge conveyor 2 for the band-shaped Packaging material 4 with tape take-off 5 and separating device 6 for separating the tape-shaped packaging material 4 into a tray-forming packaging material strip 7 and a head strapping strip 8. It can be seen that the tray-forming packaging material strip 7 and the head strapping strip 8 are guided vertically between the feed conveyor 1 and the head of the discharge conveyor 2. In this area, the packaging station 9 is arranged with its usual tools, which are not shown.

Die Vorrichtung erlaubt das Anlegen einer aus bandförmigem Verpackungsmaterial 4, welches von einem Coil 10 abgezogen wird, aufgebauten Verpackung an eine Mehrzahl von gleichen, im Ausführungsbeispiel kubischen Packgutelementen 11, die zu einer Packgutgesamtheit 12 zusammengefügt sind.The device permits the application of a packaging constructed from band-shaped packaging material 4, which is drawn off from a coil 10, to a plurality of the same, in the exemplary embodiment cubic packaging material elements 11, which are combined to form a packaging material assembly 12.

Die Packgutgesamtheit 12 wird auf dem Zuführförderer 1 der Verpackungsstation 9 zugeführt. Das Verpackungsmaterial 4 wird von dem Coil 10 abgezogen und beim Abziehen in einen traybildenden Verpackungsmaterialstreifen 7 sowie in einen Kopfumreifungsstreifen 8 aufgetrennt. Der traybildende Verpackungsmaterialstreifen 7 sowie der Kopfumreifungsstreifen 8 werden gemeinsam unter Bildung eines Abstandsspaltes 13, der der Höhe der Packgutgesamtheit 12 angepaßt ist, vertikal der Verpackungsstation 9 zugeführt. Der eigentliche Verpackungsvorgang wird dadurch herbeigeführt, daß die Packgutgesamtheit 12 mit einer vorderen Stirnseite voraus an der Verpackungsstation 9 quer zu dem traybildenden Verpackungsmaterialstreifen 7 und dem Kopfumreifungsstreifen 8 so verschoben und auf den Abführförderer 2 aufgeschoben wird, daß der Verpackungsmaterialstreifen 7 sowie der Kopfumreifungsstreifen 8 die Packgutgesamtheit 12 U-förmig umschlingt, wie es in der Fig. 1 dargestellt ist, jedoch so, daß an der rückwärtigen Stirnseite Überstände 14, 15 des traybildenden Verpackungsmaterialstreifens 7 sowie des Kopfumreifungsstreifens 8 bleiben, die von den zulaufenden Streifen 7, 8 abgetrennt wurden. Die Enden des traybildenden Verpackungsmaterialstreifens 7 sowie des Kopfumreifungsstreifens 8 werden mit den Enden der Überstände 14, 15 zu Umreifungen miteinander verbunden. Vergleicht man die Fig. 1 und 2, so erkennt man, daß die über den Bodenrand 16 einer Packgutgesamtheit 12 überstehenden Bereiche des traybildenden Verpackungsmaterialsstreifens 7 zu einem Trayrand 17 (Fig. 1) oder zu einem Trayboden 18 (Fig. 2) gefaltet und fixiert werden können. Die in bezug auf die Anlegung der Verpackung wesentlichen Verfahrensschritte werden an der auf dem Abführförderer 2 aufliegenden Packgutgesamtheit 12 durchgeführt, wobei eine Straffumreifung verwirklicht wird. Dabei kann kontinuierlich oder taktweise gearbeitet werden.The packaged goods assembly 12 is fed to the packaging station 9 on the feed conveyor 1. The packaging material 4 is pulled off the coil 10 and, when pulled off, is separated into a tray-forming packaging material strip 7 and into a head strapping strip 8. The tray-forming packaging material strip 7 and the head strapping strip 8 are fed vertically to the packaging station 9 together to form a spacing gap 13 which is adapted to the height of the packaged goods 12. The actual packaging process is brought about in that the packaged goods assembly 12, with a front end face ahead at the packing station 9, is displaced transversely to the tray-forming packaging material strip 7 and the head strapping strip 8 and pushed onto the discharge conveyor 2 in such a way that the packaging material strip 7 and the head strapping strip 8 the packaged goods assembly 12 in a U-shape, as shown in FIG. 1, but in such a way that projections 14, 15 of the tray-forming packaging material strip 7 and of the head strapping strip 8 remain on the rear end face and have been separated from the tapering strips 7, 8. The ends of the tray-forming packaging material strip 7 and the head strapping strip 8 are with the ends of the protrusions 14, 15 connected to each other for strapping. Comparing FIGS. 1 and 2, it can be seen that the areas of the tray-forming packaging material strip 7 protruding beyond the bottom edge 16 of a packaged goods unit 12 are folded and fixed to a tray edge 17 (FIG. 1) or to a tray bottom 18 (FIG. 2) can be. The essential process steps with regard to the creation of the packaging are carried out on the packaged goods assembly 12 resting on the discharge conveyor 2, with a tight strapping being realized. You can work continuously or intermittently.

Im Rahmen der Erfindung können der traybildende Verpackungsmaterialstreifen 7 und die Kopfumreifungsstreifen 8 durch Längsfaltungen besonders gestaltet sein. Das zeigt die Fig. 4 mit den Teilfiguren 4a, 4b und 4c. Die Figuren zeigen jeweils links einen Querschnitt und rechts eine Ansicht, ausschnittsweise. Man erkennt in der Fig. 4a, daß der traybildende Verpackungsmaterialstreifen 7 vor dem Zuführen zur Verpackungsstation 9 durch eine Längsfaltung 19 mit einem Doppelstreifenbereich 20, der an die Seitenwände der Packgutgesamtheiten 12 angelegt wird, und mit einem Einfachstreifenbereich 21, der den Trayrand 17 oder den Trayboden 18 bildet, versehen wird. Die im Doppelstreifenbereich aneinanderliegenden Teile des traybildenden Verpackungsmaterialstreifens 7 können miteinander verklebt werden, was in der Fig. 4a durch eine gestrichelte Linie bei dem Bezugszeichen 22 angedeutet wurde. Man erkennt in den Fig. 4b und 4c, daß der Kopfumreifungsstreifen 8 vor dem Zuführen zur Verpackungsstation durch zwei Längsfaltungen 19 verdoppelt werden kann. Die umgeklappten Bereiche liegen stoß nebeneinander, wie es die Fig. 4b zeigt oder mit einem Abstand 23, wie es die Fig. 4c zeigt.Within the scope of the invention, the tray-forming packaging material strip 7 and the head strapping strip 8 can be specially designed by longitudinal folds. This is shown in FIG. 4 with the sub-figures 4a, 4b and 4c. The figures each show a cross section on the left and a view on the right, in sections. It can be seen in Fig. 4a that the tray-forming packaging material strip 7 before being fed to the packaging station 9 by a longitudinal fold 19 with a double strip area 20, which is applied to the side walls of the packaged goods 12, and with a single strip area 21, which the tray edge 17 or Trayboden 18 forms, is provided. The parts of the tray-forming packaging material strip 7 lying in the double strip area can be glued to one another, which was indicated in FIG. 4a by a broken line at reference number 22. 4b and 4c that the head strapping 8 can be doubled by two longitudinal folds 19 before being fed to the packaging station. The folded-over areas lie side by side, as shown in FIG. 4b or at a distance 23, as shown in FIG. 4c.

Der Kopfumreifungsstreifen 8 muß nicht notwendig am oberen Rand der Packgutgesamtheit 12 angeordnet werden. Er kann auch im mittleren Bereich der Höhe der Packgutgesamtheit 12 angeordnet werden, und zwar mit mehr oder weniger großem Abstand von dem traybildenden Materialstreifen 7.The head strapping strip 8 does not necessarily have to be arranged on the upper edge of the packaged goods assembly 12. It can also be arranged in the central region of the height of the packaged goods 12, with a more or less large distance from the tray-forming material strip 7.
