Definitions
- the invention relates to a device and a method for automatically removing a film wrapping from palletized product stacks according to claim 1.
- EP 0 720 564 A1 describes a device and a method in which, to remove a film hood pulled over a stack of goods, in which the film hood is cut open vertically on one side of the stack of goods, a cut edge is grasped and attached to a winding mandrel and the winding mandrel is then guided around the stack of goods and in doing so the film is wound onto the winding mandrel rotating about its longitudinal axis.
- the film is cut vertically with a knife and in the process lifted off the stack in sections by a suction device.
- these devices can automatically process homogeneous pallets wrapped in foil.
- the object of the present invention is to provide an improved alternative that works better in particular in the case of inhomogeneously or mixedly stacked pallets.
- the cutting head for separating a film wrapping of palletized product stacks is designed with a cutting element for severing the film, the cutting element being arranged between at least two opposite contact elements and set back relative to the film contact plane formed by the opposite contact elements to form a cutting cavity and with a vacuum unit for sucking the area of the foil wrap to be cut locally into the cutting cavity for interaction with the cutting element, it is possible, both manual and automated, to always guide the cutting head along the surface of the foil-wrapped stack and the foil only lift off in the area of the cutting element, so that a safe and reliable separation is achieved.
- the cutting head is always in contact with the film surface of the stack via the contact elements when cutting.
- the recessed cutting cavity hides the cutting tool or cutting element from accidental contact.
- the contact elements are preferably designed as sliding elements and/or rolling elements.
- the sliding elements can, for. B. skids, for example, have a friction-reducing surface. This is an advantage since the foils are often "sticky".
- the rolling elements can, for. B. roles.
- the cutting head has a cutting element for the actual cutting of the foil.
- the cutting element can be, for example, a fixed or rotating knife, a glow wire or an arc torch.
- the arc torch is preferred because it cuts all types of foil particularly reliably.
- the film is only locally sucked into the cutting cavity for interaction with the cutting element when it is cut with a vacuum unit.
- the vacuum unit can have at least one suction opening, next to which the cutting element is placed. Two (or more) suction openings can preferably also be provided, between which the cutting element is arranged (possibly centrally).
- the invention also relates to the use of at least one corresponding cutting head in an automated device with a pallet space for arranging the correspondingly wrapped pallet with film, the cutting head being arranged at one end of a support arm that can be moved in such a way that the cutting head is always above the two opposite contact elements in Plant on the foil when cutting.
- the support arm is designed to be movable both vertically and horizontally by a motor, controlled by a controller, in such a way that the cutting head always rests against the film during cutting. This has the particular advantage that the support arm can always keep the cutting head in contact with the film, even with an irregular contour, thanks to the multiple mobility.
- the controller can have a device that determines the pressing force of the cutting head on the film and allows regulation.
- the device can e.g. B. have a tactile sensor, the data are fed into the controller to allow regulation.
- the motorized drive of the support arm can have a torque monitor, the data from which is fed into the controller in order to allow regulation.

- the device is designed like a portal, so that the support arm is part of a portal frame on which the support arm is then motor-driven movably adjustable, wherein the pallet staging area is arranged on a conveyor that runs through the portal.
- the support arm can also be designed as part of a multi-axis industrial robot.
- pallet also includes other similar loading aids.
- figure 1 1 shows a device, denoted as a whole by 1, for automatically removing a film wrapping from palletized product stacks.
- the device has a cutting head 2 for severing the film which is wrapped around a stack 3A on a pallet 3B.
- the pallet 3B with the wrapped stack 3A is provided on an assembly pallet place 4 which lies on a roller conveyor 5 passing through the gantry 6 of the apparatus.
- the cutting head 2 is arranged at one end of an L-shaped support arm 7 on a carriage 13 so that it can be moved in such a way that it can be moved both vertically and horizontally by a motor controlled by a controller 10 in such a way that the cutting head 2 is always in contact with the film when cutting .
- This is indicated by the arrows 11, 12.
- the support arm 7 is articulated on the portal head via a rotary device 8, so that the entire support arm 7 can be pivoted around the pallet 3B or stack 3A, in order to z. B. to remove the severed foil at the end.
- the motorized adjustment of the carriage 13 has a torque monitor 21, which feeds the controller 10 with data on the contact force of the cutting head 2, so that the concern can be regulated.
- a vacuum hose 9 runs from the cutting head 2 along the support arm 7 to the rotary device 8 and is acted upon by a pump 14 which is accommodated in the rotary device 8 and is also controlled by the control 10 .
- the cutting head 2 is in detail in the Figures 2 and 3 shown in two different versions. These are largely the same, but differ in the specific design of the cutting element itself.
- the cutting element for cutting through the foil is an arc torch 15, while in the variant according to FIG figure 3 the cutting element consists of fixed knives 15*.
- the respective cutting element 15 is arranged between two opposite rollers 16 as a contact element and opposite the film contact plane 20 formed by the opposite rollers 16 (cf. figure 4 ) set back to form a cutting cavity 17.
- rollers 16 and cutting element 15 are attached to a housing 18 which provides the spaced axes for the rollers 16 and the clearance for the cutting cavity 17.
- the housing 18 is connected to the end facing away from the cutting cavity 17 with the vacuum hose 9, so that the cutting cavity 17 has a grid-like Suction port 19 is connected to the vacuum pump 14 for sucking the portion of the film wrap to be cut locally into the cutting cavity 17 for interaction with the cutting element.
- the respective cutting element 15 is arranged centrally on the grid of the suction opening 19 . Suction openings are therefore arranged around the respective cutting element 15 .
- the pallet 3B with the wrapped stack 3A is positioned below the portal 6 on the staging area 4 on the conveyor 5.
- the cutting head 2 is positioned at the upper edge of the stack 3A and moved up to the foil via the support arm 7 or carriage 13 .
- the vacuum is then applied to the cutting head 2 via the pump 14 and the cutting element 15 cuts through the film when the head 2 is moved down.
- the contact force of the cutting head 2 is constantly checked and adjusted via the torque monitor 21 and the controller 10, so that it is in contact despite the irregular contour.
- the cutting element 15 is opened if necessary (arc burner), but the vacuum is left and the support arm 7 is now pivoted around the stack 3A via the rotating device, so that the film is pulled off.

Description
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum automatischen Entfernen einer Folienumwicklung von palettierten Produktstapeln nach Anspruch 1.The invention relates to a device and a method for automatically removing a film wrapping from palletized product stacks according to
Zur Ladungssicherung werden auf Paletten gestapelte Produkte nach dem Bilden des Stapels häufig mit Stretchfolie umwickelt oder mit einer Schrumpfhauben-Folierung versehen, so dass die Produkte nicht beim Transport verrutschen.To secure the load, products stacked on pallets are often wrapped in stretch film or provided with a shrink hood film after the stack has been formed, so that the products do not slip during transport.
Allerdings ist es schwierig diese Folienumwicklung später beim Entpacken zu entfernen. Daher wird dies häufig noch manuell durchgeführt.However, it is difficult to remove this foil wrapping later when unpacking. Therefore, this is often still done manually.
Aus
Diese Vorrichtungen können schon im Prinzip automatisiert mit Folie umwickelte homogene Paletten bearbeiten.In principle, these devices can automatically process homogeneous pallets wrapped in foil.
Allerdings besteht gerade für inhomogen oder gemischt bestapelte Paletten noch Bedarf nach besser funktionierenden Mechanismen, da diese aufgrund der ungleichmäßigen Kontur bisher nicht gut bearbeitbar sind.However, there is still a need for better-functioning mechanisms, especially for inhomogeneously or mixedly stacked pallets, since these have not been easy to process due to the uneven contour.
Demgegenüber besteht die Aufgabe der vorliegenden Erfindung darin, eine verbesserte Alternative bereitzustellen, die insbesondere bei inhomogen oder gemischt bestapelten Paletten besser funktioniert.In contrast, the object of the present invention is to provide an improved alternative that works better in particular in the case of inhomogeneously or mixedly stacked pallets.
Diese Aufgabe wird durch den in Anspruch 1 wiedergegebenen Schneidkopf und der in Anspruch 7 angegebenen Vorrichtung gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen und der Beschreibung.This object is achieved by the cutting head set forth in
Erfindungsgemäß ist erkannt worden, dass wenn der Schneidkopf zum Auftrennen einer Folienumwicklung von palettierten Produktstapeln mit einem Schneidelement zum Durchtrennen der Folie ausgestaltet ist, wobei das Schneidelement zwischen mindestens zwei gegenüberliegenden Kontaktelementen angeordnet ist und gegenüber der von den gegenüberliegenden Kontaktelementen ausgebildeten Folienanlageebene zur Ausbildung einer Schneidhöhle zurückversetzt ist, und mit einer Vakuumeinheit zum Ansaugen des lokal zu schneidenden Bereichs der Folienumwicklung in die Schneidhöhle zur Wechselwirkung mit dem Schneidelement, es möglich ist, sowohl manuell als auch automatisiert, den Schneidkopf immer auf der Oberfläche des mit Folie umwickelten Stapels entlangzuführen und die Folie nur im Bereich des Schneidelements abzuheben, sodass eine sichere und zuverlässige Auftrennung erreicht wird.According to the invention, it has been recognized that when the cutting head for separating a film wrapping of palletized product stacks is designed with a cutting element for severing the film, the cutting element being arranged between at least two opposite contact elements and set back relative to the film contact plane formed by the opposite contact elements to form a cutting cavity and with a vacuum unit for sucking the area of the foil wrap to be cut locally into the cutting cavity for interaction with the cutting element, it is possible, both manual and automated, to always guide the cutting head along the surface of the foil-wrapped stack and the foil only lift off in the area of the cutting element, so that a safe and reliable separation is achieved.
Mit anderen Worten, der Schneidkopf ist beim Auftrennen immer über die Kontaktelemente in Kontakt mit der Folienoberfläche des Stapels.In other words, the cutting head is always in contact with the film surface of the stack via the contact elements when cutting.
Dies ist insbesondere wichtig bei gemischten Stapeln, also Stapeln aus unterschiedlichen Artikeln, da diese eine unregelmäßige Außenkontur ausbilden und die Folie somit ebenfalls eine unregelmäßige Kontur ausbildet und der Kontakt eine sichere und zuverlässige Auftrennung ermöglicht.This is particularly important in the case of mixed stacks, ie stacks of different articles, since these form an irregular outer contour and the film therefore also forms an irregular contour and the contact enables safe and reliable separation.
Die zurückversetzte Schneidhöhle verbirgt das Schneidwerkzeug bzw. Schneidelement vor zufälligen Berührungen.The recessed cutting cavity hides the cutting tool or cutting element from accidental contact.
Vorzugsweise sind die Kontaktelemente als Gleitelemente und/oder Abrollelemente ausgebildet. Die Gleitelemente können z. B. Gleitkufen sein, die beispielsweise eine reibungsvermindernde Oberfläche aufweisen. Dies ist von Vorteil, da die Folien häufig "klebrig" sind.The contact elements are preferably designed as sliding elements and/or rolling elements. The sliding elements can, for. B. skids, for example, have a friction-reducing surface. This is an advantage since the foils are often "sticky".
Die Abrollelemente können z. B. Rollen sein.The rolling elements can, for. B. roles.
Denkbar ist auch die Verwendung von mehr als zwei gegenüberliegenden Kontaktelementen. So kann es vorteilhaft sein, die Schneidhöhle zwischen zwei Paaren von gegenüberliegenden Kontaktelementen anzuordnen. Dann kann der Schneidkopf weniger leicht kippen, da er an vier Punkten geführt wird.The use of more than two opposing contact elements is also conceivable. So it may be advantageous to cavity the cutting between two couples to be arranged by opposite contact elements. Then the cutting head can tilt less easily because it is guided at four points.
Zum eigentlichen Auftrennen der Folie weist der Schneidkopf ein Schneidelement auf. Das Schneidelement kann beispielsweise ein starres oder rotierendes Messer, ein Glühdraht oder ein Lichtbogenbrenner sein. Bevorzugt ist der Lichtbogenbrenner, da dieser besonders zuverlässig alle Arten von Folien schneidet.The cutting head has a cutting element for the actual cutting of the foil. The cutting element can be, for example, a fixed or rotating knife, a glow wire or an arc torch. The arc torch is preferred because it cuts all types of foil particularly reliably.
Erfindungsgemäß wird die Folie beim Auftrennen mit einer Vakuumeinheit nur lokal in die Schneidhöhle zur Wechselwirkung mit dem Schneidelement angesaugt. Die Vakuumeinheit kann dazu mindestens eine Ansaugöffnung aufweisen, neben der das Schneidelement platziert ist. Vorzugsweise können auch zwei (oder mehr) Ansaugöffnungen vorgesehen sein, zwischen denen das Schneidelement (ggf. zentral) angeordnet ist.According to the invention, the film is only locally sucked into the cutting cavity for interaction with the cutting element when it is cut with a vacuum unit. For this purpose, the vacuum unit can have at least one suction opening, next to which the cutting element is placed. Two (or more) suction openings can preferably also be provided, between which the cutting element is arranged (possibly centrally).
Die Erfindung betrifft auch den Einsatz mindestens eines entsprechenden Schneidkopfes in einer automatisierten Vorrichtung mit einem Palettenplatz für die Anordnung der entsprechend mit Folie umwickelten Palette, wobei der Schneidkopf an einem Ende eines derart verfahrbaren Tragarms angeordnet ist, dass der Schneidkopf immer über den zwei gegenüberliegenden Kontaktelementen in Anlage an der Folie beim Schneiden ist.The invention also relates to the use of at least one corresponding cutting head in an automated device with a pallet space for arranging the correspondingly wrapped pallet with film, the cutting head being arranged at one end of a support arm that can be moved in such a way that the cutting head is always above the two opposite contact elements in Plant on the foil when cutting.
In einer bevorzugten Ausführungsform ist der Tragarm sowohl vertikal als auch horizontal motorisch über eine Steuerung gesteuert derart verfahrbar ausgebildet, dass der Schneidkopf immer beim Schneiden an der Folie anliegt. Dies hat insbesondere den Vorteil, dass der Tragarm den Schneidkopf über die mehrfache Beweglichkeit immer in Kontakt mit der Folie auch bei unregelmäßiger Kontur halten kann.In a preferred embodiment, the support arm is designed to be movable both vertically and horizontally by a motor, controlled by a controller, in such a way that the cutting head always rests against the film during cutting. This has the particular advantage that the support arm can always keep the cutting head in contact with the film, even with an irregular contour, thanks to the multiple mobility.
Dazu kann die Steuerung eine Einrichtung aufweisen, die die Andruckkraft des Schneidkopfes an der Folie bestimmt und eine Regelung zulässt.For this purpose, the controller can have a device that determines the pressing force of the cutting head on the film and allows regulation.
Die Einrichtung kann z. B. einen taktilen Sensor aufweisen, dessen Daten in die Steuerung eingespeist werden, um eine Regelung zu erlauben. Alternativ oder zusätzlich kann der motorische Antrieb des Tragarms eine Drehmomentüberwachung aufweisen, deren Daten in die Steuerung eingespeist werden, um eine Regelung zu erlauben.The device can e.g. B. have a tactile sensor, the data are fed into the controller to allow regulation. Alternatively or additionally, the motorized drive of the support arm can have a torque monitor, the data from which is fed into the controller in order to allow regulation.
Die Vorrichtung kann verschiedenste Ausgestaltungen aufweisen. In einer bevorzugten Ausführungsform ist die Vorrichtung portalartig ausgebildet, so dass der Tragarm Bestandteil eines Portalgestells ist, an dem der Tragarm dann motorisch beweglich verstellbar ist, wobei der Palettenbereitstellplatz auf einem Förderer angeordnet ist, der durch das Portal verläuft. Alternativ kann der Tragarm auch als Teil eines Mehrachsen-Industrieroboters ausgebildet sein.The device can have a wide variety of configurations. In a preferred Embodiment, the device is designed like a portal, so that the support arm is part of a portal frame on which the support arm is then motor-driven movably adjustable, wherein the pallet staging area is arranged on a conveyor that runs through the portal. Alternatively, the support arm can also be designed as part of a multi-axis industrial robot.
Es versteht sich, dass der Begriff Palette auch andere ähnliche Ladehilfsmittel umfasst.It goes without saying that the term pallet also includes other similar loading aids.
