Description

Die Erfindung betrifft eine Vorrichtung zum Schrumpfen von Schrumpfhauben, die einen palettierten Gutstapel umgeben, - mit einer Schrumpfeinrichtung, mit einem an der Schrumpfeinrichtung vorbeiführenden Transportsystem für die palettierten Gutstapel, mit einer unterhalb der Schrumpfeinrichtung angeordneten Hubeinrichtung zum Anheben der palettierten Gutstapel und mit einem im Bereich der Hubeinrichtung angeordneten Sauggebläse.The invention relates to a device for shrinking shrink hoods that surround a palletized stack of goods, with a shrinking device, with a transport system for the palletized stack of goods that leads past the shrinking device, with a lifting device arranged underneath the shrinking device for lifting the palletized stack of goods, and with one in the area the lifting device arranged suction fan.

Bei einer bekannten Vorrichtung dieser Gattung (EP-0S 0 133 462) werden die palettierten und ggf. bereits mit einer Schrumpfhaube versehenen Gutstapel auf einem Förderer, z.B. einem Rollenförderer bis in den Bereich der Schrumpfeinrichtung gebracht. Dort wird der palettierte Gutstapel mit einer unter dem Förderer angeordneten Hubeinrichtung, die als Scherenhebetisch ausgebildet ist, angehoben, so daß die unteren Ränder der Schrumpfhaube frei über die Unterseite der Palette hängen. Mit Hilfe des am Scherenhebetisch angeordneten Sauggebläses werden dann die freien Ränder gegen die Unterseite der Palette gesaugt und mit Hilfe der Schrumpfeinrichtung geschrumpft, so daß ein sogenannter Unterschrumpf entsteht. Dann wird der palettierte Gutstapel wieder auf dem Rollenförderer abgesetzt und der Rest der Schrumpfhaube geschrumpft.In a known device of this type (EP-0S 0 133 462) the palletized and possibly already provided with a shrink hood stack of goods are brought on a conveyor, for example a roller conveyor, into the area of the shrinking device. There, the palletized stack of goods is lifted with a lifting device arranged under the conveyor, which is designed as a scissor lifting table, so that the lower edges of the shrink hood are free above the underside of the pallet hang. With the help of the suction blower arranged on the scissor lifting table, the free edges are then sucked against the underside of the pallet and shrunk using the shrinking device, so that a so-called undershrinkage occurs. Then the palletized stack of goods is put back on the roller conveyor and the rest of the shrink hood shrunk.

Für den innerbetrieblichen Transport von Gütern gibt es fahrerlose Transportsysteme mit Elektrotraktoren und von diesen geschleppten Karren, wobei die Elektrotraktoren über im Boden verlegte Induktionsschleifen geführt und gesteuert, d.h auch angehalten oder gestartet werden können. Bei Einsatz dieser Transportsysteme zusammen mit einer Vorrichtung zum Schrumpfen müßten die Hubeinrichtung und das Sauggebläse unterflur angeordnet werden, damit der Elektrotraktor die auf den Karren angeordneten Gutstapel unter die Schrumpfeinrichtung bringen kann. Das erfordert aufwendige Konstruktionen und Installationen für die Hubeinrichtung und das Sauggebläse.For the internal transport of goods there are driverless transport systems with electric tractors and carts towed by them, whereby the electric tractors are guided and controlled via induction loops laid in the ground, i.e. they can also be stopped or started. If these transport systems are used together with a device for shrinking, the lifting device and the suction fan would have to be arranged under the floor so that the electric tractor can bring the stacks of goods arranged on the carts under the shrinking device. This requires complex constructions and installations for the lifting device and the suction fan.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs beschriebenen Gattung so zu verbessern, daß beim Einsatz von Transportsystemen mit insbesondere fahrerlosen, automatisch gesteuerten Flurförderzeugen auf unterflur angeordnete Einrichtungen verzichtet werden kann.The object of the invention is to improve a device of the type described in the introduction in such a way that, when using transport systems with in particular driverless, automatically controlled industrial trucks, devices arranged under the floor can be dispensed with.

Diese Aufgabe wird dadurch gelöst, daß die Hubeinrichtung neben der Bahn des Transportsystems angeordnet ist und wenigstens einen heb- und senkbaren Träger aufweist, der bis unter einen vom Transportsystem herangeführten palettierten Gutstapel bewegbar ist, wobei der Träger davon abstehende Auflager für den palettierten Gutstapel aufweist und die Auflager aus einer horizontalen in eine vertikale Stellungbewegbar sind. Die gesamte Hubeinrichtung ist damit neben der Bahn des Transportsystems und unterhalb der Schrumpfeinrichtung angeordnet, so daß der Aufwand für eine Grube und die die darin unterzubringenden Aggregate überflüssig ist. Durch entsprechende Steuerung der Bewegungen einerseits des oder der Träger und andererseits der Auflager können die Auflager so unter die Palette gebracht werden, daß mit ihrer Hilfe die Palette und der darauf befindliche Gutstapel von der Stellfläche des Karrens abgehoben werden kann. Es versteht sich, daß der Karren bzw. die Karren, auf denen palettierte Gutstapel herangeführt werden, Stellflächen besitzen, die so ausgebildet sind, daß die Auflager an der Unterseite der Palette angreifen können.This object is achieved in that the lifting device is arranged next to the path of the transport system and has at least one lifting and lowering carrier which can be moved up to below a palletized stack of goods brought up by the transport system, the carrier having protruding supports for the stacked stack of goods and the supports from a horizontal in a vertical position can be moved. The entire lifting device is thus arranged next to the path of the transport system and below the shrinking device, so that the effort for a pit and the units to be accommodated therein is superfluous. By appropriately controlling the movements of the carrier or carriers and the support, the supports can be placed under the pallet in such a way that the pallet and the stack of goods on it can be lifted off the surface of the cart. It is understood that the trolley or trolleys on which palletized stacks of goods are brought in have storage areas which are designed in such a way that the supports can act on the underside of the pallet.

Die Steuerung der Schwenkbewegung der Auflager wird besonders einfach, wenn zwei oder mehr Träger vorgesehen sind und die Träger um ihre Längsachsen verschwenkbar sind. Dann können die Auflager starr an den Trägern befestigt werden.The control of the pivoting movement of the supports becomes particularly simple if two or more supports are provided and the supports can be pivoted about their longitudinal axes. Then the supports can be rigidly attached to the beams.

Bevorzugt sollen die Träger in Richtung ihrer Längsachsen, also quer zur Bahn des Transportsystems verschiebbar sein. Dazu können die Träger in einem Antriebsgehäuse gelagert sein, welche Antriebe und Führungen für die Längsverschiebung der Träger und für ihre Schwenkbewegung aufweist und welches seinerseits an einem Ständer vertikal auf- und abbewegbar ist. Da in den meisten Fällen die Schrumpfeinrichtung ebenfalls an einem oder mehreren vertikalen Ständern geführt ist, kann auch das Antriebsgehäuse an dem oder den Ständern der Schrumpfeinrichtung geführt sein.The carriers should preferably be displaceable in the direction of their longitudinal axes, that is to say transversely to the path of the transport system. For this purpose, the carriers can be mounted in a drive housing which has drives and guides for the longitudinal displacement of the carriers and for their pivoting movement and which in turn can be moved vertically up and down on a stand. Since in most cases the shrinking device is also guided on one or more vertical stands, the drive housing can also be guided on the stand or stands of the shrinking device.

Für die Absaugung von Luft unterhalb der Palette empfiehlt sich eine Ausführung, bei der der oder die Träger aus Rohren bestehen, die an das Sauggebläse angeschlossen sind und Lufteintrittsöffnungen aufweisen.For the extraction of air below the pallet, a version is recommended in which the or Carriers consist of pipes which are connected to the suction fan and have air inlet openings.

Im folgenden wird ein in der Zeichnung dargestelltes Ausführungsbeispiel der Erfindung erläutert; die einzige Figur zeigt schematisch eine Ansicht einer Vorrichtung zum Schrumpfen.In the following an embodiment of the invention shown in the drawing is explained; the single figure shows schematically a view of a device for shrinking.

Die in der Zeichnung dargestellte Vorrichtung dient zum Schrumpfen von Schrumpfhauben, die einen palettierten Gutstapel umgeben. Gutstapel 1 sind auf einer Palette 2 angeordnet, die auf der Stellfäche 3 eines Karrens 4 abgestellt sind. Ein oder mehrere Karren 4 werden von einem nicht dargestellten Elektrotraktor geschleppt, der über im Boden verlegte Induktionsschleifen durch die Fabrikhalle gesteuert und angehalten sowie gestartet werden kann. Ein mit einem Gutstapel 1 beladener Karren 4 wird vor einer Schrumpfeinrichtung angehalten. Zu dieser Schrumpfeinrichtung gehören ein oder mehrere vertikale Ständer 5, an denen ein Schrumpfrahmen 6 auf- und abbeweglich ist. Der Schrumpfrahmen 6 besitzt eine innere Öffnung, die etwas größer ist als der Querschnitt des Gutstapels 1. An der Innenseite des Öffnungsrandes befinden sich Heizeinrichtungen, z.B. Brenner, deren heiße Verbrennungsgase auf den Gutstapel 1 gerichtet sind, so daß bei einer Auf- oder Abbewegung des Schrumpfrahmens 6 eine den Gutstapel 1 umgebende Schrumpfhaube geschrumpft wird.The device shown in the drawing serves to shrink shrink hoods that surround a palletized stack of goods. Good stacks 1 are arranged on a pallet 2, which are placed on the storage space 3 of a cart 4. One or more carts 4 are towed by an electric tractor, not shown, which can be controlled and stopped and started through the factory floor via induction loops laid in the floor. A cart 4 loaded with a stack of goods 1 is stopped in front of a shrinking device. This shrinking device includes one or more vertical stands 5, on which a shrinking frame 6 can be moved up and down. The shrink frame 6 has an inner opening which is somewhat larger than the cross section of the stack of goods 1. On the inside of the opening edge there are heating devices, e.g. Burners, the hot combustion gases of which are directed onto the stack of goods 1, so that when the shrinking frame 6 moves up or down, a shrink hood surrounding the stack of goods 1 is shrunk.

An den Ständern 5 ist auch ein Antriebsgehäuse 7 vertikal auf- und abbeweglich geführt. Im Antriebsgehäuse 7 sind zwei zueinander parallele Träger 8 gehalten, von denen in der Zeichnung nur einer sichtbar ist. Die Träger 8 können mit Hilfe zugeordneter Antriebe, die nicht gezeichnet sind, in Richtung ihrer Längsachsen horizontal soweit verschoben werden, daß sie entweder die gezeichnete Position einnehmen oder sich außerhalb des Karrens 4 befinden. Die Träger 8 können außerdem mit Hilfe zugeordneter Antriebe um ihre Längsachsen verschwenkt werden.On the stands 5, a drive housing 7 is guided vertically up and down. Two mutually parallel supports 8 are held in the drive housing 7, only one of which is visible in the drawing. The carrier 8 can be shifted horizontally so far in the direction of their longitudinal axes with the aid of associated drives, which are not shown, that they either take the drawn position or are outside the cart 4. The carriers 8 can also be pivoted about their longitudinal axes with the aid of associated drives.

An dem dem Karren 4 zugewandten Ende besitzt jeder Träger zwei im Abstand voneinander angeordnete Auflager 10, die radial vom Träger 8 abstehen. Durch Verschwenken der Träger 8 können die Auflager 10 aus einer horizontalen Stellung in die dargestellte vertikale Stellung gebracht werden.At the end facing the cart 4, each carrier has two spaced-apart supports 10 which project radially from the carrier 8. By pivoting the carrier 8, the supports 10 can be brought from a horizontal position into the vertical position shown.

Die Träger 8 bestehen aus Rohren mit Lufteintrittsöffnungen 11 auf demjenigen Abschnitt, der sich in der gezeichneten Funktionsstellung unterhalb der Palette 2 befindet. Außerdem sind die rohrförmigen Träger 8 an ein nicht dargetelltes Sauggebläse angeschlossen.The carrier 8 consist of tubes with air inlet openings 11 on the section which is in the functional position shown below the pallet 2. In addition, the tubular carrier 8 are connected to a suction fan, not shown.

Die dargestellte Vorrichtung arbeitet wie folgt:
Ein mit einem Gutstapel 1 beladener Karren 4 wird vor der Schrumpfeinrichtung angehalten. Die Träger 8 werden in Richtung ihrer Längsachse durch entsprechende, nicht dargestellte Ausnehmungen des Karrens 4 in den Karren bis unter die Palette 2 bewegt, wobei die Auflager 10 sich in horizontaler Stellung befinden. Dann werden die Träger 8 um ihre Längsachsen geschenkt, bis die Auflager 10 eine vertikale Stellung einnehmen, die in der Zeichnung dargestellt ist. Es versteht sich, daß auch die Stellfäche 3 des Karrens entsprechende Ausnehmungen aufweist, damit die Auflager 10 in die vertikale Position geschwenkt werden können um nach dem Anheben der Träger 8 mit Hilfe des Antriebsgehäuses 7 die Unterseite der Palette 2 erfassen können. Bei weiterem Anheben der Träger 8 wird dann die Palette 2 mit dem darauf befindlichen Gutstapel 1 von der Stellfläche 3 des Karrens 4 abgehoben, und zwar soweit, bis die Ränder einer in der Zeichnung nicht dargestellten, über den Gutstapel 1 und die Palette 2 gezogenen Schrumpfhaube frei bis unter die Unterseite der Palette 2 hängen. Nach dem Einschalten des Sauggebläse, welches Luft durch die Lufteintrittsöffnungen 11 der rohrförmigen Träger 8 von der Unterseite der Palette absaugt, legen sich die frei herabhängenden Ränder der Schrumpfhaube unter die Unterseite der Palette. Nunmehr kann die Schrumpfhaube geschrumpft werden, wobei entweder die Palette 2 mit den untergeschlagenen Rändern der Schrumpfhaube zunächst wieder auf der Stellfäche 3 abgesetzt wird oder und zunächst die unter die Unterseite der Palette geschlagenen Ränder der Schrumpfhaube geschrumpft werden. Nachdem die Schrumpfhaube vollständig geschrumpft ist und die Palette 2 wieder auf den Karren 4 abgesetzt worden ist, werden die Träger 8 soweit abgesenkt, daß die Auflager 10 durch Verschwenken der Träger 8 wieder in horizontale Position gebracht werden können. Anschließend werden die Träger 8 durch Längsverschieben aus dem Bereich des Karrens 4 gezogen, der dann weiterfahren kann.The device shown works as follows:
A cart 4 loaded with a stack of goods 1 is stopped in front of the shrinking device. The carriers 8 are moved in the direction of their longitudinal axis through corresponding, not shown recesses of the cart 4 in the cart to below the pallet 2, the supports 10 being in the horizontal position. Then the carriers 8 are given about their longitudinal axes until the supports 10 assume a vertical position, which is shown in the drawing. It goes without saying that the footprint 3 of the trolley has corresponding recesses so that the supports 10 can be pivoted into the vertical position in order to be able to grasp the underside of the pallet 2 with the aid of the drive housing 7 after the carrier 8 has been raised. When the carrier 8 is raised further, the pallet 2 with the stack of goods 1 located thereon is removed from the storage space 3 of the cart 4 lifted, until the edges of a shrink hood, not shown in the drawing, pulled over the stack of goods 1 and the pallet 2 hang freely below the underside of the pallet 2. After switching on the suction fan, which sucks air through the air inlet openings 11 of the tubular carrier 8 from the underside of the pallet, the freely hanging edges of the shrink hood lie under the underside of the pallet. Now the shrink hood can be shrunk, either the pallet 2 with the folded edges of the shrink hood is first placed back on the shelf 3 or and first the edges of the shrink hood folded under the underside of the pallet are shrunk. After the shrink hood has shrunk completely and the pallet 2 has been placed on the cart 4 again, the supports 8 are lowered to such an extent that the supports 10 can be brought back into a horizontal position by pivoting the supports 8. The carriers 8 are then pulled longitudinally out of the area of the cart 4, which can then continue to move.
