Abstract

The invention relates to a method and an arrangement for the unpacking and packing of containers from and into corresponding receptacles, such as cardboard boxes, bottle cases or the like which are used in a continuous work process, mainly in a sector of the drinks industry. The containers (6.9) located in the receptacles (7.1; 7.2) are picked up according to colour, shape or height and abnormal containers (6 or 9) are removed from the receptacles by means of gripper elements of a container-packing machine and the empty places are filled by identical containers (6 or 9). <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren und eine Anordnung zum Aus- und Einpacken von Behältern aus bzw. in entsprechende Behältnisse, wie Kartonagen, Flaschenkästen oder ähnlichem, welche in einem kontinuierlichen Arbeitsprozeß, hauptsächlich im Bereich der Getränkeindustrie, zum Einsatz kommen.The invention relates to a method and an arrangement for unpacking and packing containers out of or into corresponding containers, such as cardboard boxes, bottle crates or the like, which are used in a continuous working process, mainly in the area of the beverage industry.

Bekannt sind Vorrichtungen zum Aussortieren von Behältern, insbesondere Flaschen nach Höhe und Form aus einer Reihe von gleichartig angeordneten Behältern.Devices are known for sorting out containers, in particular bottles according to their height and shape, from a series of containers arranged in the same way.

Der Prozeß des Sortieren von den aus den Behältnissen aufgenommenen Berhältereihen erfolgte bekannterweise so, daß die in Formationen (z. B. Flaschenkästen) ankommenden Behälter mittels der Greiferelemente einer Behälterauspackmaschine bzw. per Hand komplett aufgenommen werden, um auf eine Abgabeeinrichtung (Flaschentisch) abgesetzt werden.The process of sorting the rows of containers received from the containers is known to take place such that the containers arriving in formations (e.g. bottle crates) are completely picked up by means of the gripper elements of a container unpacking machine or by hand in order to be placed on a delivery device (bottle table) .

Von dieser Abgabeeinrichtung aus erfolgt über Leit- und Transporteinrichtungen die Auflösung der Kastenformation in eine Reihenformation.From this delivery device, the box formation is broken down into a row formation via guidance and transport devices.

In dieser Formation werden die Behälter durch eine Farb-, Form- bzw. Höhenerkennung geführt. Befinden sich abartige Behälter in dieser Reihe, so erfolgt die Aussonderung aus diesem Behälterstrom.In this formation, the containers are guided by color, shape and height detection. If there are abnormal containers in this row, they are separated from this container stream.

Diese bekannte Lösung hat den Nachteil, daß sie nur mit einem hohen Aufwand, wie lange Transport- und Leiteinrichtungen (großer Puffertisch) realisiert wird. Außerdem müssen die durch die im Behälterstrom entstandenen Lücken geschlossen werden.This known solution has the disadvantage that it can only be implemented at great expense, such as long transport and guiding devices (large buffer table). In addition, the gaps created by the flow of containers must be closed.

Der Erfindung liegt die Aufgabe zugrunde, den kontinuierlichen Arbeitsprozeß bereits mit selektierten Behältern aufgefüllte Behältnisse bereitzustellen.The invention has for its object to provide the continuous work process already filled with selected containers.

Erfindungsgemäß wird die Aufgabe wie in den kennzeichnenden Teilen der Patentansprüche beschrieben, gelöst.According to the invention the object is achieved as described in the characterizing parts of the claims.

Durch die Einbindung der Erfindung in eine Anlage zum Abfüllen von Flüssigkeiten oder ähnlichen in entsprechende Behälter ist es möglich, die erforderlichen und sortierten Behälter bereitzustellen.By incorporating the invention into a system for filling liquids or the like into appropriate containers, it is possible to provide the required and sorted containers.

The invention will be explained in more detail using an exemplary embodiment. The accompanying drawing shows:

Arrangement of the switching elements on the support arm of a container unpacking and packing device
Fig. 2
different layer patterns that occur in the containers
Fig 3

Fig. 4
Representation of the arrangement in which the color recognition takes place after the selection of the container.

Entsprechend Fig 1 sind die Schaltelemente 1 auf einen Tragarm 2 fest angebracht. Dieser Tragarm 2 ist in der Lage, eine horizontale und vertikale Bewegung auszuführen. Die im Ausführungsbeispiel verwendeten Schaltelemente 1 sind elektropneumatisch gesteuerte 5/2 Impulsventile in Blockbauweise. Jedes einzelne Schaltelement 1 ist über eine Pneumatikleitung 3 mit dem eigentlichen Greiferelement 4 verbunden. Im Ausführungsbeispiel sind es pneumatisch aufblasbare Greiferelemente 4.According to Fig. 1, the switching elements 1 are firmly attached to a support arm 2. This support arm 2 is capable of horizontal and vertical movement. The switching elements 1 used in the exemplary embodiment are electro-pneumatically controlled 5/2 pulse valves in block design. Each individual switching element 1 is connected to the actual gripper element 4 via a pneumatic line 3. In the exemplary embodiment, there are pneumatically inflatable gripper elements 4.

Über eine vorgeschaltete Farb-, Form- bzw. Höhenerkennung 5 wird mittels eines innermaschinellen Steuerprogrammes der Anordnung ein elektrisches Steuersignal an das einzelne Schaltelement weitergegeben. Alle Schaltelemente 1, die dieses Signal erhalten, werden geschaltet und über die Pneumatikleitung 3 wird das entsprechende Greiferelement 4 betätigt, d. h. es können einzelne Behälter 6 oder 9 aus der vorgegebenen Formation 12 (Behältnisse 7.1 oder 7.2) aufgenommen werden.An electrical control signal is passed on to the individual switching element via an upstream color, shape or height detection 5 by means of an internal machine control program of the arrangement. All switching elements 1 that receive this signal are switched and the corresponding gripper element 4 is actuated via the pneumatic line 3, ie individual containers 6 or 9 can be picked up from the predetermined formation 12 (containers 7.1 or 7.2).

Die aufgenommenen Behälter 6 oder 9 werden auf eine gesonderte Fördereinrichtung abgegeben.The received containers 6 or 9 are delivered to a separate conveyor.

Je nach Art und Form der Behälter 6, 9 können unterschiedliche Greiferköpfe 8 am Tragarm 2 befestigt werden.Depending on the type and shape of the containers 6, 9, different gripper heads 8 can be attached to the support arm 2.

Nachdem die selektierten Behälter 6 od. 9 aus dem Behältnis 7.1 und 7.2 entfernt wurden, erfolgt eine Leerstellenerkennung 11 und die Leerstellen werden durch gleichartige Behälter 6 oder 9 wieder aufgefüllt.After the selected containers 6 or 9 have been removed from the container 7.1 and 7.2, a vacancy detection is carried out 11 and the vacancies are filled up again by containers 6 or 9 of the same type.

In der Fig 3 und 4 wird neben dem Gesamtablauf dargestellt, daß es auch möglich ist, farblich unterschiedliche Behältnisse 7.1 und 7.2 zu selektieren.3 and 4, in addition to the overall process, it is shown that it is also possible to select differently colored containers 7.1 and 7.2.

In der Fig 3 wird dargestellt, wie diese vor der Selektierung der einzelnen Behälter 6 oder 9 erfolgt und in der Fig 4 wie dies nach der Selektierung der einzelnen Behälter 6 oder 9 gelöst wurde.FIG. 3 shows how this takes place before the individual containers 6 or 9 are selected and FIG. 4 shows how this was solved after the individual containers 6 or 9 were selected.

Dies wird dadurch erreicht, daß der gesamten Anordnung eine Farberkennung 10 vorgeschaltet ist, die dann die entsprechenden Impulse an eine Steuereinrichtung gibt, welche dann z. B. eine Weiche betätigt und die die entsprechenden Behältnisse 7.2 auf eine gesonderte Fördereinrichtung leitet.This is achieved in that the entire arrangement is preceded by a color detection 10, which then gives the corresponding pulses to a control device, which then z. B. actuated a switch and which leads the corresponding containers 7.2 to a separate conveyor.

Die Darstellung in der Fig 1 ist Bestandteil der Behälteraus- und -einpackvorrichtungen 13 und 14.The representation in FIG. 1 is part of the container unpacking and packing devices 13 and 14.
