Vorrichtung zum Übergeben von Kunststoffbeuteln, insbesondere an eine Sammeleinrichtung in einer BeutelherstellungsmaschineDevice for transferring plastic bags, in particular to a collecting device in a bag manufacturing machine
Technisches GebietTechnical field
Die Erfindung betrifft eine Vorrichtung zum Übergeben von Kunststoffbeuteln, insbesondere an eine Sammeleinrichtung einer Beutelherstellungsmaschine, mit einem Flügelrad bestehend aus einer zentralen Hohlwelle, die mit einem Drehantrieb verbunden und an eine Unterdruckquelle angeschlossen ist, sowie mehreren an der Hohlwelle radial abstehend befestigten Flügelarmen, die im Inneren als Saugkanal gestaltet sind und auf einer Längsseite eine Saugfläche mit mehreren Saugöffnungen aufweisen.The invention relates to a device for transferring plastic bags, in particular to a collecting device of a bag making machine, with an impeller consisting of a central hollow shaft, which is connected to a rotary drive and connected to a vacuum source, as well as several wing arms attached radially protruding from the hollow shaft Inside are designed as a suction channel and have a suction surface with a plurality of suction openings on one long side.
Stand der TechnikState of the art
Bei der Herstellung von Kunststoffbeuteln aus Kunststoffolienbahnen werden bekannterweise die durch Trennschweißen abgetrennten Kunststoffbeutel zu Stapeln mit einer vorbestimmten Beutelanzahl zusammengefaßt. Zur Übergabe der nacheinander angeförderten Beutel an eine Sammeleinrichtung werden sogenannte Flügelrad-Übergabevorrichtungen eingesetzt, die Flügelarme mit Saugkanälen und Saugöffnungen aufweisen, an denen die Beutel mittels Unterdruck gehalten werden. Als Sammeleinrichtungen werden bekannterweise sogenannte Stiftstapelfördereinrichtungen verwendet, bei denen die Kunststoffbeutel auf Stapelstifte abgelegt werden. Flügelrad-Übergabevorrichtungen der gattungsgemäßen Art, die vor Stiftstapeleinrichtungen angeordnet sind, sind vielfach bekannt und in der DE 44 20 975-A1 , der DE 198 58 559-A1 und der DE 199 32 365-A1 beschrieben.In the production of plastic bags from plastic film webs, the plastic bags separated by welding are known to be combined into stacks with a predetermined number of bags. So-called impeller transfer devices are used to transfer the successively conveyed bags to a collecting device, which have wing arms with suction channels and suction openings, on which the bags are held by means of negative pressure. As known, so-called pin stack conveyors are used as collecting devices, in which the plastic bags are placed on stack pins. Vane wheel transfer devices of the generic type, which are arranged in front of pin stacking devices, are widely known and described in DE 44 20 975-A1, DE 198 58 559-A1 and DE 199 32 365-A1.
Da die Kunststoffbeutel beim Übergeben um 180 °C gewendet und auf Stapelstifte aufgesteckt werden, ist es erforderlich, sie sicher an den Flügelarmen zu halten. Dazu ist bei den bekannten Vorrichtungen ein Unterdruckgebläse mit hoher Leistung erforderlich, insbesondere wenn Beutel übergeben werden sollen, die an einer Seite keine geradlinige, sondern eine bogenförmige Form aufweisen und so nicht über ihre gesamte Breite auf den äußeren Flügelarm aufliegen.Since the plastic bags are turned by 180 ° C and placed on stacking pegs during transfer, it is necessary to hold them securely on the wing arms. For this purpose, a vacuum blower with high performance is required in the known devices, in particular if bags are to be handed over which are on one side have no straight, but an arcuate shape and so do not rest over their entire width on the outer wing arm.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt daher die Aufgabe zugrunde, bei einer Übergabevorrichtung der gattungsgemäßen Art die Saugkraft an den Flügelarmen zu verbessern, ohne daß die Leistung des Sauggebläses erhöht werden muß.The invention is therefore based on the object of improving the suction power on the wing arms in a transfer device of the generic type without the power of the suction fan having to be increased.
Diese Aufgabe wird nach der Lösung gemäß Patentanspruch 1 dadurch gelöst, daß die Saugfläche der Flügelarme Saugöffnungen mit einem Durchmesser zwischen 3 mm und 12 mm, vorzugsweise zwischen 6 mm und 9 mm aufweist und daß der von den Saugöffnungen gebildete offene Anteil an der gesamten Saugfläche mehr als 3 %, vorzugsweise mehr als 5 %, beträgt.This object is achieved according to the solution according to claim 1 in that the suction surface of the wing arms has suction openings with a diameter between 3 mm and 12 mm, preferably between 6 mm and 9 mm and that the open portion formed by the suction openings in the entire suction surface more than 3%, preferably more than 5%.
Eine weitere Lösung zur Steigerung der Saugkraft besteht darin, daß der Saugkanal gemäß Patentanspruch 2 im Bereich unterhalb der Saugfläche einen verringerten Querschnitt aufweist.Another solution for increasing the suction force is that the suction channel has a reduced cross section in the area below the suction surface.
Das Ansaugen der Beutel an die Saugfläche wird verbessert, wenn die Saugöffnungen gemäß Patentanspruch 3 als Düsen mit sich nach außen erweiterndem Querschnitt ausgebildet sind.The suction of the bags on the suction surface is improved if the suction openings are designed as nozzles with a cross section that widens outwards.
Bei der besonders vorteilhaften Ausgestaltung nach Patentanspruch 4 wird die Saug- fläche von der Außenfläche eines leistenförmigen Durchgangsbohrungen aufweisendes Einsat∑stückes gebildet, das in den Flügelarm auf den Saugkanal in einem Bereich mit verringertem Querschnitt so aufgesetzt ist, daß seine Außenfläche mit der benachbarten Außenfläche des Flügelarms fluchtet.In the particularly advantageous embodiment according to claim 4, the suction surface is formed by the outer surface of a strip-shaped through-hole insert which is placed in the wing arm on the suction channel in a region with a reduced cross-section such that its outer surface is in contact with the adjacent outer surface of the Wing arm is aligned.

Wege zur Ausführung der ErfindungWays of Carrying Out the Invention
Die in den Figuren dargestellte Vorrichtung dient zum Übergeben von Kunststoffbeuteln 1 , die aus einer doppellagigen Kunststoffolienbahn 2 durch Quertrennschweißen mittels einer Trennschweißeinrichtung 3 herstellt werden, zu einer Sammeleinrichtung 4. Sie ist Bestandteil einer Beutelmaschine, bei der die hergestellten Beutel 1 in Stapeln gesammelt und so zu Beutelpaketen zusammengefaßt werden. Bevorzugt werden die Beutel eines Paketes anschließend verblockt.The device shown in the figures is used to transfer plastic bags 1, which are produced from a double-layer plastic sheet 2 by cross-cut welding by means of a cut-off welding device 3, to a collecting device 4. It is part of a bag machine in which the bags 1 produced are collected in stacks and so on can be combined into bag packages. The bags of a package are then preferably blocked.
Die Sammeleinrichtung 4 ist bevorzugt als sogenannter Stiftstapler ausgebildet. Sie weist einen taktweise angetriebenen Längsförderer auf, an dem Stapelstifte 5 befestigt sind. Die Beutel 1 weisen an einer Seite Sammelöffnungen auf, mit denen sie über die Stifte 5 gezogen und so übereinander abgelegt und gestapelt werden.The collecting device 4 is preferably designed as a so-called pen stacker. It has a cyclically driven longitudinal conveyor to which stacking pins 5 are fastened. The bags 1 have collection openings on one side, with which they are drawn over the pins 5 and are thus placed one above the other and stacked.
Die Übergabevorrichtung enthält ein Flügelrad 6, daß aus einer zentralen Hohlwelle 7 und mehreren, an der Hohlwelle 7 befestigten Flügelarmen 8 besteht. Die Hohlwelle 7 ist mit einem Drehantrieb 9 verbunden und an ein Sauggebläse als Unterdruckquelle ange-schlossen, so daß in ihrem Inneren ein Unterdruck erzeugt werden kann. An der Hohlwelle 7 sind mehrere Flügelarme 8 radial abstehend befestigt, deren Inneres als Saug-kanal 10 gestaltet ist. Ein Flügelarm ist in den Figuren 3 und 4 vergrößert dargestellt:The transfer device contains an impeller 6, which consists of a central hollow shaft 7 and several, attached to the hollow shaft 7 wing arms 8. The hollow shaft 7 is connected to a rotary drive 9 and connected to a suction fan as a vacuum source, so that a vacuum can be generated in its interior. A plurality of wing arms 8 are fastened to the hollow shaft 7 in a radially projecting manner, the interior of which is designed as a suction channel 10. A wing arm is shown enlarged in FIGS. 3 and 4:
Jeder Flügelarm 8 hat die Form einer Hohlleiste, an deren Befestigungsende ein Stutzen 15 befestigt ist und die an ihrem anderen, freien Ende verschlossen ist. Mit dem offenen Stutzen 15 wird der Flügelarm 8 an der zentralen Hohlwelle 7 befestigt und an die Unterdruckquelle angeschlossen. Auf einer Längsseite weist die als Saugkanal 10 dienende Hohlleiste eine Saugfläche 16 mit mehreren Saugöffnungen 11 auf. Die Saugöffnungen 11 in der Saugfläche 16 haben einen Durchmesser zwischen 3 mm und 12 mm, bevorzugt zwischen 6 mm und 9 mm. Der von den Saugöffnungen 11 gebildete offene Anteil an der gesamten Saugfläche 16 beträgt mehr als 3 %, vorzugsweise mehr als 5 %. Im vorliegenden Ausführungsbeispiel beträgt die Saugfläche 16 ca. 3.500 mm. Die vier Saugöffnungen in der Saugfläche 16 haben jeweils einen Durchmesser von 8 mm, so daß der offene Anteil der Saugfläche 16 etwa 5,7 % beträgt.Each wing arm 8 has the shape of a hollow strip, at the fastening end of which a connecting piece 15 is fastened and which is closed at its other, free end. With the open connector 15, the wing arm 8 is attached to the central hollow shaft 7 and connected to the vacuum source. On one long side, the hollow strip serving as suction channel 10 has a suction surface 16 with a plurality of suction openings 11. The suction openings 11 in the suction surface 16 have a diameter between 3 mm and 12 mm, preferably between 6 mm and 9 mm. The open portion of the total suction surface 16 formed by the suction openings 11 is more than 3%, preferably more than 5%. In the present exemplary embodiment, the suction surface 16 is approximately 3,500 mm. The four suction openings in the suction surface 16 each have a diameter of 8 mm, so that the open portion of the suction surface 16 is approximately 5.7%.
Bevorzugt wird die Saugfläche 16 von der Außenfläche eines leistenförmigen Einsatzstückes 12 gebildet, das in Figur 3 in einer ausgebauten Position dargestellt ist. Das Einsatzstück 12 weist als Saugöffnungen 11 Durchgangsbohrungen 13 auf, die mit dem Saugkanal 10 verbunden sind. Das Einsatzstück 12 wird in den Flügelarm 8 auf den Saugkanal 10 aufgesetzt und mittels Schrauben 14 festgeschraubt. Die als Saugkanal 10 dienende Hohlleiste weist in dem Einsatzbereich eine um die Höhe des Einsatzstücks 12 verringerte Höhe auf, so daß die die Saugfläche 16 bildende Außenfläche des eingesetzten Einsatzstückes mit der Außenfläche des Flügelarm 8 fluchtet. Aufgrund der verringerten Höhe der Hohlleiste weist der Saugkanal 15 im Bereich unterhalb der Saugfläche 16 einen verringerten Querschnitt auf. Dies führt zu einer Erhöhung der Strömungsgeschwindigkeit und somit zu einer verbesserten Saugwirkung.The suction surface 16 is preferably formed by the outer surface of a strip-shaped insert 12, which is shown in a removed position in FIG. 3. The insert 12 has through holes 13 as suction openings 11, which are connected to the suction channel 10. The insert 12 is placed in the wing arm 8 on the suction channel 10 and screwed down by means of screws 14. The hollow strip serving as suction channel 10 has a reduced height in the area of use by the height of the insert 12, so that the outer surface of the insert used which forms the suction surface 16 is aligned with the outer surface of the wing arm 8. Due to the reduced height of the hollow strip, the suction channel 15 has a reduced cross section in the area below the suction surface 16. This leads to an increase in the flow rate and thus to an improved suction effect.
Bevorzugt sind die Durchgangsbohrungen 13 als Düsen mit sich nach außen erweiternden Querschnitt ausgebildet, wie in Figur 3 dargestellt ist. Die düsenförmige Gestaltung der Bohrungen 13 vergrößert die Saugkraft, mit der ein Beutel 1 in Richtung zu dem Flügelarm 8 gezogen wird. The through bores 13 are preferably designed as nozzles with an outwardly widening cross section, as shown in FIG. 3. The nozzle-shaped design of the bores 13 increases the suction force with which a bag 1 is pulled in the direction of the wing arm 8.
