    In den Zeichnungen sind als Beispiel Einzelheiten einer Verpackungsmaschine für Verpackungen 10, nämlich Zigaretten-Verpackungen, gezeigt. Konkret handelt es sich um Weichbecher-Packungen, also einen Typ einer Zigaretten-Verpackung 10, bei dem eine Zigaretten-Gruppe von einem Innenzuschnitt aus Papier oder Stanniol und ein so gebildeter Zigaretten-Block von einem Becher aus Papier umhüllt ist. Die Verpackung 10 hat eine quaderförmige Gestalt mit großflächiger Vorderwand 11, gegenüberliegender Rückwand 12 und langgestreckten, schmalen Seitenwänden 13 und 14.In the drawings, details of a packaging machine are exemplified for packaging 10, namely cigarette packaging, shown. Specifically, they are soft cup packs, thus a type of cigarette packaging 10, at which a group of cigarettes from an inner blank of paper or tinfoil and a cigarette block from is wrapped in a paper cup. The packaging 10 has a cuboid shape with a large front wall 11, opposite rear wall 12 and elongated, narrow Side walls 13 and 14.

    Die Verpackungen 10 befinden sich bei dem vorliegenden Beispiel im Austrittsbereich einer Verpackungsmaschine. Die Verpackungen 10 haben einen Trockenrevolver verlassen und werden durch einen Bandförderer 15 transportiert. Dieser ist Teil einer Verpackungsmaschine, wie sie in Einzelheiten in EP 605 838 gezeigt und beschrieben ist.The packaging 10 is in the present example in the exit area of a packaging machine. The packing 10 have left a drying turret and are transported by a belt conveyor 15. This is part a packaging machine, as described in detail in EP 605 838 is shown and described.

    Der Bandförderer 15 fördert die Verpackungen 10 positionsgerecht zwischen Mitnehmern 16, derart, daß die Verpackungen 10 in Förderrichtung einen deutlichen Abstand voneinander haben. Der Bandförderer 15 besteht aus einem Zahnriemen, der auf einer bogenförmigen Unterlage 17 geführt ist und einen bogenförmigen Fördertrum 18 für die Verpackungen 10 bildet.The belt conveyor 15 conveys the packaging 10 in the correct position between carriers 16 such that the packaging 10 have a clear distance from each other in the conveying direction. The belt conveyor 15 consists of a toothed belt on an arcuate base 17 is guided and an arcuate Forming conveyor strand 18 for the packaging 10.

    Die Verpackungen 10 werden durch den Bandförderer 15 einem Abförderer 19 zugeführt. Dieser transportiert die Verpackungen 10 mit dem vorgegebenen Abstand voneinander einem weiteren Verwendungszweck zu, beispielsweise einer Verpackungsmaschine zum Anbringen einer Außenumhüllung aus Folie. Der Abförderer besteht hier aus einem oberen Fördergurt 20 und einem unteren Fördergurt 21. Zwischen einander zugekehrten, im wesentlichen horizontal verlaufenden Fördertrumen dieser Fördergurte 20 und 21 werden die Verpackungen 10 transportiert, und zwar derart, daß die quergerichteten, nach oben und unten weisenden Seitenwände 13, 14 an den Fördertrumen der Fördergurte 20, 21 anliegen.The packages 10 are one by the belt conveyor 15 Abförderer 19 supplied. This transports the packaging 10 with the predetermined distance from each other Purpose, for example a packaging machine for attaching an outer covering made of foil. Of the Abförderer consists of an upper conveyor belt 20 and a lower conveyor belt 21. essentially horizontal conveying strands of these Conveyor belts 20 and 21, the packages 10 are transported, in such a way that the transverse, upward and bottom-facing side walls 13, 14 on the conveying strands the conveyor belts 20, 21 abut.

    Die von dem Bandförderer 15 angelieferten Verpackungen 10 werden von diesem nicht unmittelbar an den Abförderer 19 übergeben, sondern über einen Zwischenförderer in Gestalt eines Sternrades 22. Dieses nimmt nacheinander die Verpackungen 10 vom Fördertrum 18 des Bandförderers 15 ab und übergibt sie an den Abförderer 19.The packaging 10 delivered by the belt conveyor 15 are not sent directly to the conveyor 19 passed, but via an intermediate conveyor in the form of a star wheel 22. This takes the packaging one after the other 10 from the conveyor strand 18 of the belt conveyor 15 and passes them to the conveyor 19.

    Aus verschiedenen Gründen ist es erforderlich bzw. wünschenswert, einzelne, vorbestimmte Verpackungen 10 aus dem vorstehend beschriebenen Förderfluß auszusondern. Dies gilt insbesondere für fehlerhaft ausgebildete Verpackungen 10, also Fehlpackungen 23. Der Fehler kann dabei in mangelnder Ausbildung oder mangelnder Anzahl der Zigaretten oder in fehlerhafter Umhüllung liegen. Die Fehler werden an anderer, geeigneter Stelle der Verpackungsmaschine identifiziert. Ein daraus abgeleitetes Steuersignal wird einem Aussonderungsaggregat 24 zugeführt. Dieses schleust die betreffende Fehlpackung 23 aus dem Transportfluß aus, im vorliegenden Falle im Bereich des Bandförderers 15. Des weiteren kann das Aussonderungsaggregat 24 Probepackungen 25 aussondern, also intakte Verpackungen 10, die beispielsweise einer Kontrolle zugeführt werden.For various reasons, it is necessary or desirable individual, predetermined packages 10 from the above to discard the flow described. This is especially true for faulty packaging 10, so Wrong packs 23. The mistake can be in a lack of training or insufficient number of cigarettes or defective Wrapping lie. The errors will be different, more appropriate Location of the packaging machine identified. One of them derived control signal is a screening unit 24th fed. This ejects the faulty pack 23 in question the transport flow from, in the present case in the area of Belt conveyor 15. Furthermore, the separating unit Discard 24 sample packs 25, i.e. intact packaging 10, which are fed to a control, for example.

    Das Aussonderungsaggregat 24 besteht hier aus zwei je für sich wichtigen Teilaggregaten. Es handelt sich dabei zum einen um einen Entnahmeförderer für die Verpackungen 10, der hier als Ausschleuserad 26 ausgebildet ist. Zum anderen handelt es sich um ein Abfördersystem für die ausgeschleusten Verpackungen 10. The screening unit 24 consists of two for each important sub-assemblies. It is about one for a removal conveyor for the packaging 10, the is designed here as a discharge wheel 26. On the other hand it is a conveyor system for the discharged Packaging 10.

    Das Ausschleuserad 26 ist ein walzenförmiges Gebilde mit längs des Umfangs angeordneten Aufnahmen 27 für je eine auszuschleusende Verpackung 10. Das Ausschleuserad 26 ist in einer solchen Relativstellung zur Bewegungsbahn der Verpackungen 10 positioniert, daß die zu erfassenden Verpackungen 10 durch eine der Aufnahmen 27 im Bereich der radial nach außen gerichteten, freien Packungsfläche erfaßt werden, nämlich an der großflächigen Vorderwand 11.The discharge wheel 26 is a roller-shaped structure with recordings 27 arranged along the circumference for one each to be discharged Packaging 10. The discharge wheel 26 is in one such position relative to the path of movement of the packaging 10 positioned that the packaging to be detected 10 through one of the receptacles 27 in the area of the radially outward directional, free packaging area can be detected, namely the large front wall 11.

    Die Aufnahmen 27 sind jeweils im Bereich tangential verlaufender, also durch Abflachung gebildeter Lagerflächen 28 des Ausschleuserads 26 an diesem angeordnet. Die Aufnahmen 27 bestehen aus Organen, die die Verpackung 10 durch Saugluft, also durch Unterdruck und Ansaugen erfassen und halten. Bei dem vorliegenden Ausführungsbeispiel besteht zu diesem Zweck jede Aufnahme 27 aus mehreren - hier aus drei - Saugköpfen, 29. Die (drei) Saugköpfe 29 sind im Bereich der ebenen Lagerfläche 28 in Axialrichtung des Ausschleuserads 26 nebeneinander angeordnet. Bei dem gezeigten Beispiel (Fig. 7) ist der mittlere Saugkopf 29 gegenüber den randseitigen Saugköpfen 29 in Umfangsrichtung versetzt angeordnet. Die Saugköpfe 29 bestehen aus elastischem Werkstoff, insbesondere Gummi. Radialgerichtete Saugbohrungen 30 - bei dem vorliegenden Beispiel jeweils eine mittige Saugbohrung 30 - münden an äußeren kreisflächenförmigen Anlageflächen 31 der Saugköpfe 29. Bei der Aufnahme einer Verpackung 10 durch das Ausschleuserad 26 liegen die Saugköpfe 29 mit ihren Anlageflächen 31 an der nach oben bzw. außen weisenden Packungsfläche an und werden durch den Unterdruck gehalten.The receptacles 27 are each tangential in the area, thus by flattening formed bearing surfaces 28 of the Ausleuserads 26 arranged on this. The recordings 27 exist from organs that the packaging 10 by suction air, So capture and hold by negative pressure and suction. At the present embodiment exists for this purpose each receptacle 27 from several - here from three - suction heads, 29. The (three) suction heads 29 are in the area of the plane Bearing surface 28 in the axial direction of the discharge wheel 26 arranged side by side. In the example shown (Fig. 7) is the middle suction head 29 compared to the edge-side suction heads 29 arranged offset in the circumferential direction. The suction heads 29 consist of elastic material, in particular Rubber. Radial suction bores 30 - in the present Example, each a central suction hole 30 - open outer circular contact surfaces 31 of the suction heads 29. When a packaging 10 is picked up by the discharge wheel 26 are the suction heads 29 with their contact surfaces 31 on the packing surface facing upwards or outwards on and are held by the negative pressure.

    Die hier kreisförmigen bzw. zylindrischen Saugköpfe 29 sind vorzugsweise als Gummi-Metall-Elemente ausgebildet mit einer metallischen Tragplatte (nicht gezeigt) und einem an dieser angebrachten, metallischen Gewindezapfen 69. Dieser sitzt mit einem Außengewinde in einer Gewindebohrung 64 der Lagerfläche 28. Die (zentrische) Saugbohrung 30 führt durch den Gewindezapfen 69 hindurch zu einer radialen Anschlußbohrung 65 im Ausschleuserad 26. Die Anschlußbohrungen 65 der Saugköpfe 29 sind untereinander verbunden durch eine achsparallele Querbohrung 66.The circular or cylindrical suction heads 29 here preferably designed as rubber-metal elements with a metallic support plate (not shown) and one on this attached, metallic threaded pin 69. This sits with an external thread in a threaded bore 64 of the bearing surface 28. The (central) suction bore 30 leads through the threaded pin 69 through to a radial connection bore 65 in the discharge wheel 26. The connection bores 65 of the suction heads 29 are interconnected by an axially parallel Cross bore 66.

    Die gemeinsame Querbohrung 66 ist über eine Radialbohrung 67 mit einer achsparallelen Bohrung 68 verbunden, die ihrerseits zu einem Kanalsegment 32 im Bereich eines feststehenden Stützorgans 33 führt. Die Kanalsegmente 32 sind in dem als Stützscheibe ausgebildeten Stützorgan 33 als kreisbogenförmige, offene Nuten angeordnet (Fig. 5). Während der Drehbewegung des Ausschleuserads 26 kommen die Saugbohrungen 30 bzw. die mit diesen verbundenen Bohrungen 68 mit den Kanalsegmenten 32 zur Überdeckung. Während dieser Phase der Drehbewegung sind die Saugbohrungen 30 an eine Unterdruckquelle angeschlossen. Wie aus Fig. 5 ersichtlich, befinden sich die Kanalsegmente 32 im Bereich der Übernahme einer Verpackung 10 vom Bandförderer 15.The common transverse bore 66 is via a radial bore 67 connected to an axially parallel bore 68, which in turn to a channel segment 32 in the area of a fixed one Support organ 33 leads. The channel segments 32 are in the as Support disc designed support member 33 as an arcuate, open grooves arranged (Fig. 5). During the rotation of the discharge wheel 26, the suction bores 30 or the holes 68 connected to these with the channel segments 32 to cover. During this phase of the rotational movement the suction bores 30 are connected to a vacuum source. As can be seen from Fig. 5, there are Channel segments 32 in the area of taking over a packaging 10 from the belt conveyor 15.

    Eine weitere Besonderheit besteht darin, daß die Aufnahmen 27 hinsichtlich der Übernahme von Verpackungen 10 gesondert steuerbar sind. Bei dem vorliegenden Ausführungsbeispiel sind zu diesem Zweck zwei konzentrisch angeordnete Kanalsegmente 32 und 34 vorgesehen. Die Radialbohrungen 67 und die hieran anschließenden quergerichteten Bohrungen 68 sind so positioniert, daß eine Gruppe der Aufnahmen 27 dem radial außen liegenden Kanalsegment 32 und die anderen Aufnahmen 27 dem radial innen liegenden Kanalsegment 34 zugeordnet sind. Die Anordnung ist so getroffen, daß in Drehrichtung des Ausschleuserads 26 die Aufnahmen 27 abwechselnd dem einen und dem anderen Kanalsegment 32, 34 zugeordnet sind. Die Kanalsegmente 32, 34 sind über eigene Absperrventile mit der gemeinsamen Unterdruckquelle verbunden. Die Absperrventile werden je nach der zu beaufschlagenden Aufnahme 27 geschaltet. Es ist deshalb sichergestellt, daß über das eine oder andere Kanalsegment 32, 34 die jeweils aktive Aufnahme 27 zum Erfassen einer Verpackung mit Saugluft beaufschlagt ist. Hierdurch wird vermieden, daß infolge der extrem kurzen Taktzeiten und der Trägheit der Schaltvorgänge eine in Förderrichtung nachfolgende Verpackung 10 durch eine nachfolgende Aufnahme 27 mit übernommen wird.Another special feature is that the receptacles 27 with regard to the takeover of packaging 10 separately are controllable. In the present embodiment for this purpose two concentrically arranged channel segments 32 and 34 provided. The radial bores 67 and this subsequent transverse bores 68 are positioned that a group of the receptacles 27 the radially outer Channel segment 32 and the other receptacles 27 the radial inner channel segment 34 are assigned. The order is made so that in the direction of rotation of the discharge wheel 26 the recordings 27 alternately one and the other Channel segment 32, 34 are assigned. The channel segments 32, 34 have their own shut-off valves with the common one Vacuum source connected. The shut-off valves are depending on the receptacle 27 to be acted on. It is therefore ensured that over one or the other channel segment 32, 34 the respectively active receptacle 27 for detecting a Packaging is loaded with suction air. This avoids that due to the extremely short cycle times and Inertia of the switching operations follow one in the conveying direction Packing 10 with a subsequent receptacle 27 is taken over.

    Das topfartig ausgebildete Ausschleuserad 26 ist über eine Antriebswelle 35 mit einem Antriebsrad 36 verbunden. Die Antriebswelle 35 ist in einer Stützwand 37 eines Maschinengestells gelagert.

Zwischen dem Stützorgan 33 und dem Ausschleuserad 26 ist eine Anlaufscheibe 41 positioniert. Diese dreht mit dem Ausschleuserad 26. Die Anlaufscheibe 41 besteht aus einem Material von hoher Abriebfestigkeit, zum Beispiel aus Kohlenstoff. Die Bohrung 68 führt durch diese Anlaufscheibe 41 hindurch. Sie liegt eng an dem Stützorgan 33 an.The stationary support member 33 is non-rotatable by means of pin 39 mounted on the drive shaft 35 and by springs 40 supported elastically on the support wall 37. Between the support organ 33 and the discharge wheel 26 is a thrust washer 41 positioned. This turns with the discharge wheel 26. The thrust washer 41 is made of a material with high abrasion resistance, for example made of carbon. The bore 68 leads through this thrust washer 41. It is tight the support member 33.

    Die durch das Ausschleuserad 26 erfaßte Verpackung 10 wird durch die Aufnahme 27 über eine kurze Förderstrecke, nämlich kreisbogenförmige Förderbahn, mitgenommen und einem Förderer für die ausgesonderten Verpackungen 10 zugeführt. Diese werden auf einer Plattform 42 abgelegt und dann weitertransportiert.The packaging 10 gripped by the discharge wheel 26 becomes through the receptacle 27 over a short conveyor distance, namely circular arc-shaped conveyor track, taken and a conveyor supplied for the discarded packaging 10. These will stored on a platform 42 and then transported on.

    Für diesen Übergabevorgang wird die auf die Saugorgane wirkende Saugluft der Aufnahmen 27 weggesteuert. Stattdessen werden die Verpackungen 10 im Bereich der Ablage kurzzeitig mit Druckluft beaufschlagt, und zwar über das beschriebene Kanalsystem für die Übertragung von Unterdruck. Hierfür sind in dem betreffenden Bereich der Drehbewegung des Ausschleuserads 26 Kanalsegmente in dem Stützorgan 33 gebildet. Diese Kanalsegmente sind ebenfalls als Teilkreisbogen ausgebildet und mit einer Druckluftquelle verbunden. Dadurch wird eine sichere und exakte Freigabe und Ablage der Verpackung 10 oberhalb der Plattform 42 gewährleistet. Hinsichtlich der Steuerung der Druckluft zu den Aufnahmen 27 gilt analog die Beschreibung im Zusammenhang mit dem Unterdrucksystem. Die Aufnahmen 27 sind abwechselnd dem einen und anderen Kanalsegment zugeordnet.For this transfer process, the one acting on the suction elements is used Suction air of the recordings 27 controlled away. Instead the packaging 10 in the storage area for a short time pressurized with compressed air, namely via the described Channel system for the transmission of negative pressure. For this are in the relevant area of the rotary movement of the discharge wheel 26 channel segments are formed in the support member 33. This Channel segments are also designed as partial arcs and connected to a compressed air source. This will make one Safe and exact release and storage of the packaging 10 guaranteed above platform 42. With regard to the Control of the compressed air to the receptacles 27 applies analogously to that Description in connection with the vacuum system. The Recordings 27 are alternately one and the other channel segment assigned.

    Die Plattform 42 ist der nach oben offene Anfangsbereich eines Packungsförderers 45. Dieser beginnt hier in unmittelbarer Nachbarschaft zum Bandförderer 15. Der Packungsförderer 45 transportiert die ausgesonderten Verpackungen 10, nämlich Fehlpackungen 23 und Probepackungen 25, separat vom Abförderer 19.The platform 42 is the open top area of one Packing conveyor 45. This begins here immediately Neighborhood to the belt conveyor 15.
