Description

Die vorliegende Erfindung bezieht sich auf eine Verpackungsmaschine, insbesondere eine Kammerbandmaschine.The present invention relates to a packaging machine, in particular a chamber belt machine.

Bei Verpackungsmaschinen werden hohe Anforderungen an die Reinigbarkeit und die Servicefreundlichkeit gestellt. Bei automatisierten Vakuumverpackungsmaschinen, beispielsweise bei Kammerbandmaschinen im oberen Leistungsbereich, kann der Kammerdeckel der Vakuumkammer nur vertikal bewegt werden, was es für Reinigungs- bzw. Servicepersonal schwierig macht, das Innere des Deckels zu reinigen bzw. Wartungs- oder Reparaturarbeiten durchzuführen. Zwischen dem Maschinengestell und der Deckelunterkante steht für diese Arbeiten in der Regel nur ein ca. 300mm hoher Spalt zur Verfügung. Durch diese begrenzte Zugänglichkeit kann die Arbeit nur eingeschränkt oder unter erhöhtem Aufwand durchgeführt werden. Die Erreichbarkeit und die Einsehbarkeit des Deckelinneren bei Wartungs-, Reparatur- oder Reinigungsarbeiten ist erschwert. Aus ergonomischen Gesichtspunkten sind diese Arbeiten eine hohe Belastung für den Servicetechniker bzw. das Reinigungspersonal.For packaging machines, high demands are placed on cleanability and ease of servicing. In automated vacuum packaging machines, such as high capacity chamber band machines, the chamber lid of the vacuum chamber can only be moved vertically, making it difficult for service personnel to clean the interior of the lid or to perform maintenance or repair work. Between the machine frame and the lower edge of the lid there is usually only a 300mm gap available for this work. Due to this limited accessibility, the work can only be carried out with limited or increased effort. The accessibility and the visibility of the inside of the lid during maintenance, repair or cleaning work is difficult. From an ergonomic point of view, this work is a heavy burden for the service technician or the cleaning staff.

Eine Verpackungsmaschine gemäß dem Oberbegriff des Anspruchs 1 geht aus der US 3,818,574 hervor. Eine Verpackungsmaschine mit einer Vakuumkammer, die als Ganzes rotierbar ist, ist in der WO 01/94209 A1 beschrieben. Die US 5,465,557 A offenbart schließlich eine Vakuumkammer für eine Verpackungsmaschine, deren Deckel um ein Scharnier schwenkbar ist.A packaging machine according to the preamble of claim 1 is known from US 3,818,574 out. A packaging machine with a vacuum chamber, which is rotatable as a whole, is in the WO 01/94209 A1 described. The US 5,465,557 A finally discloses a vacuum chamber for a packaging machine, the lid is pivotable about a hinge.

Die Aufgabe der vorliegenden Erfindung ist es, eine Verpackungsmaschine bereitzustellen, die die ergonomische Zugänglichkeit und die Einsehbarkeit des Deckelinneren einer Vakuumkammer einer Verpackungsmaschine für Wartungs-, Reparatur oder Reinigungsarbeiten verbessert. Die Aufgabe wird gelöst durch eine Verpackungsmaschine gemäß Anspruch 1.The object of the present invention is to provide a packaging machine which improves the ergonomic accessibility and the visibility of the inside of the lid of a vacuum chamber of a packaging machine for maintenance, repair or cleaning work. The object is achieved by a packaging machine according to claim 1.

Durch die erfindungsgemäße Schwenkbarkeit des Deckels wird die ergonomische Erreichbarkeit und die Einsehbarkeit des Deckelinneren verbessert. Wartungs-, Reparatur- oder Reinigungsarbeiten können auf diese Weise von einem Servicetechniker oder Reinigungspersonal stehend vor der Maschine durchgeführt werden. Dies ist insbesondere im Bereich der Lebensmittelverpackung bzw. beim Verpacken von medizinisch-sterilen Gütern unerlässlich, da hier strenge gesetzliche Hygienevorschriften zu beachten sind.The inventive pivotability of the lid, the ergonomic accessibility and the visibility of the lid interior is improved. Maintenance, repair or cleaning work can be carried out in front of the machine by a service technician or cleaning staff. This is particularly important in the field of food packaging or in the packaging of medical-sterile goods, since strict legal hygiene regulations must be observed.

Im Folgenden wird mit Bezug auf Fig. 1, 2a, 2b, 3a und 3b eine Ausführungsform der vorliegenden Erfindung beispielhaft an einer Kammerbandmaschine beschrieben. In der vorliegenden Ausführungsform ist die Kammerbandmaschine als automatische Kammerbandmaschine ausgebildet.The following is with reference to Fig. 1 . 2a, 2b, 3a and 3b an embodiment of the present invention described by way of example on a chamber belt machine. In the present embodiment, the chamber belt machine is designed as an automatic chamber belt machine.

Fig. 1 zeigt eine schematische Ansicht einer Kammerbandmaschine mit einem Förderband 1, einem Gestell 2, einem Auflegebereich 3, einer Vakuumkammer 4 und einem Deckel 5. Die Kammer 4 wird durch den Deckel 5 zusammen mit einem Teil des Förderbands 1 gebildet, wobei sich der Deckel 5 motorisch, pneumatisch oder hydraulisch betrieben automatisch bzw. kraftbetätigt gesteuert öffnet oder manuell öffnen lässt, um beispielsweise zu evakuierende bzw. zu versiegelnde Beutel aufzunehmen, die durch das Förderband 2 automatisch zugeführt werden, und der sich anschließend automatisch schließt, um die Kammer 4 zu bilden. Fig. 1 shows a schematic view of a chamber belt machine with a conveyor belt 1, a frame 2, a laying area 3, a vacuum chamber 4 and a lid 5. The chamber 4 is formed by the lid 5 together with a part of the conveyor belt 1, wherein the cover 5 motor operated pneumatically or hydraulically operated opens automatically or power-operated, or open manually, for example, to be evacuated or sealed bags that are automatically fed by the conveyor belt 2, and then automatically closes to form the chamber 4.

Der Deckel 5 setzt sich aus einer Deckfläche, zwei Seitenflächen und zwei Stirnflächen zusammen. In Fig. 1 befindet sich der Deckel 5 in seiner horizontalen Arbeitsposition bzw. in seiner relativ zum Förderband abgesenkten Position, in der die Deckfläche des Deckels 5 parallel zum Förderband 1 ausgerichtet ist. In dieser Position ist die Kammer 4 geschlossen.The lid 5 is composed of a top surface, two side surfaces and two end surfaces. In Fig. 1 the cover 5 is in its horizontal working position or in its lowered relative to the conveyor belt position in which the top surface of the lid 5 is aligned parallel to the conveyor belt 1. In this position, the chamber 4 is closed.

Fig. 2a,b zeigt die Kammerbandmaschine in perspektivischer Ansicht bzw. in Vorderansicht. Der Deckel 5 befindet sich in seiner horizontalen Arbeitsposition. Es ist eine Hubvorrichtung 6 vorgesehen, die eine vertikale Hubbewegung, also orthogonal zum Förderband 1, des Deckels 5 in eine angehobene Position ermöglicht, in der die Kammer 4 geöffnet ist. Die Hubvorrichtung 6 ist eine Linearführung, die auf beiden Seiten des Förderbands 1 am Gestell 2 befestigt ist. Die bewegbaren Teile der Linearführung, die den Vertikalhub des Deckels 5 realisieren sollen, sind über eine Querstrebe 8 miteinander verbunden. Der Deckel 5 ist gelenkig mit dieser Querstrebe 8 bzw. mit einem dort mittig angebrachten Gelenk 7 gelenkig verbunden. Auf diese Weise kann der Deckel 5 neben der vertikalen Translationsbewegung auch eine Rotationsbewegung um die Gelenkachse durchführen. Die Rotationsachse verläuft durch die Flächenschwerpunkte der beiden Stirnflächen des Deckels 5, um ein leichtgängiges Schwenken des Deckels 5 zu gewährleisten. Bei der Erfindung ist der Deckel 5 derart mit dem Gelenk 7 verbunden, dass die Rotationsachse durch den Massenschwerpunkt des Deckels 5 und parallel zu den beiden Unterkanten der Seitenflächen verläuft. Fig. 2a, b shows the chamber belt machine in perspective view and in front view. The lid 5 is in its horizontal working position. It is provided a lifting device 6, which allows a vertical lifting movement, ie orthogonal to the conveyor belt 1, the lid 5 in a raised position in which the chamber 4 is opened. The lifting device 6 is a linear guide which is fixed on both sides of the conveyor belt 1 on the frame 2. The movable parts of the linear guide, which are intended to realize the vertical stroke of the cover 5, are connected to one another via a transverse strut 8. The cover 5 is articulated to this cross member 8 and articulated there with a centrally mounted joint 7. In this way, the lid 5 in addition to the vertical translational movement also perform a rotational movement about the hinge axis. The axis of rotation passes through the center of gravity of the two end faces of the lid 5, to a smooth pivoting of the lid 5 to guarantee. In the invention, the cover 5 is connected to the hinge 7 in such a way that the axis of rotation passes through the center of mass of the cover 5 and parallel to the two lower edges of the side surfaces.

Fig. 3a,b zeigt die Kammerbandmaschine in perspektivischer bzw. in Vorderansicht. Der Deckel 5 befindet sich in einer vertikalen Wartungs-, Reparatur- bzw. Reinigungsposition bzw. in einer angehobenen und geschwenkten Position, im folgenden als Wartungsposition bezeichnet. Die Seitenflächen des Deckels 5 sind in dieser Position parallel zum Förderband 1. Es erstreckt sich hierbei im wesentlichen jeweils die Hälfte der Stirnflächen und der Seitenflächen des Deckels 5 oberhalb und unterhalb der Querstrebe 8. Fig. 3a, b shows the chamber belt machine in perspective or in front view. The lid 5 is located in a vertical maintenance, repair or cleaning position or in a raised and pivoted position, hereinafter referred to as maintenance position. The side surfaces of the lid 5 are in this position parallel to the conveyor belt 1. It extends here in each case substantially half of the end faces and the side surfaces of the lid 5 above and below the cross member. 8

Im Betrieb wird der Deckel 5 aus seiner Arbeitsposition (siehe Fig. 2a,b) in seine Wartungsposition (Fig. 3a,b), gebracht, um im Deckelinneren Wartungs-, Reparatur- oder Reinigungsarbeiten durchzuführen. Hierfür wird der Deckel 5 zunächst über die Hubvorrichtung 6 in vertikaler Richtung translatorisch nach oben verschoben. Durch die gelenkige Verbindung des Deckels 5 mit der Querstrebe 8 bzw. mit dem Gelenk 7 kann der Deckel 5 nach dieser Hubbewegung in eine vertikale Wartungsposition geschwenkt werden. In dieser Position ist das Deckelinnere optimal erreichbar bzw, einsehbar. Um den Deckel 5 aus der Wartungsposition wieder in die Arbeitsposition zu überführen, wird der Deckel 5 um seine Rotationsachse zurückgeschwenkt und danach über die Hubvorrichtung 6 in seine Arbeitsposition gebracht.In operation, the lid 5 from its working position (see Fig. 2a, b ) to its maintenance position ( Fig. 3a, b ), to perform maintenance, repair or cleaning work inside the lid. For this purpose, the lid 5 is first translated translationally above the lifting device 6 in the vertical direction. Due to the articulated connection of the cover 5 with the transverse strut 8 or with the joint 7, the cover 5 can be pivoted after this lifting movement into a vertical maintenance position. In this position, the interior of the lid is optimally accessible or visible. In order to transfer the cover 5 from the maintenance position back to the working position, the cover 5 is pivoted back about its axis of rotation and then brought over the lifting device 6 in its working position.

Fig. 4,5 zeigen eine nicht erfindungsgemäße Ausführungsform der vorliegenden Erfindung. Das Gelenk 7 ist außermittig auf der Querstrebe 8 angebracht. Der Deckel 5 ist dementsprechend ebenfalls außermittig mit dem Gelenk 7 verbunden, um eine korrekte Position des Deckels 5 über dem Förderband 1 zu gewährleisten. In Fig. 4 befindet sich der Deckel 5 auf einer angehobenen Position, nach der Hubbewegung aber noch vor der Schwenkbewegung des Deckels 5. In Fig. 5 befindet sich der Deckel 5 in seiner Wartungsposition. Durch die außermittige Anbringung des Deckels 5 ist nur eine geringe Hubbewegung der Hubvorrichtung 6 notwendig, um den Deckel 5 aus seiner Arbeitsposition in seine Wartungsposition zu bewegen, da sich in der Wartungsposition der größte Teil des Deckels 5 oberhalb der Querstrebe 8 erstreckt. Fig. 4.5 show a non-inventive embodiment of the present invention. The joint 7 is mounted eccentrically on the crossbar 8. The lid 5 is accordingly also off-center connected to the hinge 7 in order to ensure a correct position of the lid 5 on the conveyor belt 1. In Fig. 4 is the lid 5 in a raised position, after the lifting movement but before the pivotal movement of the lid 5. In Fig. 5 is the lid 5 in its maintenance position. Due to the eccentric mounting of the lid 5 only a small lifting movement of the lifting device 6 is necessary to move the cover 5 from its working position to its maintenance position, since in the maintenance position, the largest part of the lid 5 extends above the cross strut 8.

Da die Rotations- bzw. Schwenkachse des Deckels 5 nicht mehr durch seinen Schwerpunkt verläuft, ist eine Hilfsvorrichtung 9, beispielsweise in Form einer Gasdruckfeder oder eines Pneumatikzylinders, vorgesehen, um eine optimale Bedienbarkeit bzw. ein leichtgängiges Schwenken des Deckels 5 zu gewährleisten. Ein Ende der Hilfsvorrichtung 9 ist am Deckel 5, das andere Ende an der Querstrebe 8 angebracht.Since the rotation or pivot axis of the lid 5 no longer extends through its center of gravity, an auxiliary device 9, for example in the form of a gas spring or a pneumatic cylinder, is provided to ensure optimum operability and smooth pivoting of the lid 5. One end of the auxiliary device 9 is attached to the cover 5, the other end to the crossbar 8.
