Description
Die Erfindung betrifft eine Vorrichtung zum Transport von Folien gemäß dem Oberbegriff des Patentanspruches 1 und ein Verfahren zum Transport von Folien gemäß dem Oberbegriff des Patentanspruches 9.The invention relates to a device for transporting foils according to the preamble of claim 1 and a method for transporting foils according to the preamble of
Es sind Vorrichtungen und Verfahren zum Transport von Folien von einem Stapel zu einem Legebereich bekannt, insbesondere in Verbindung mit der Kaschierung von Werkstoffplatten mit dieser Folie in einer Laminierpresse. Folien meinen in diesem Zusammenhang flächiges Papier, Kaschiermaterial oder dergleichen, das geeignet ist auf einem Trägermaterial aufgebracht zu werden. Das Trägermaterial kann hierbei ebenfalls wieder eine Folie oder andere gleich dünne Materialien sein oder steife Materialien wie z. B. Werkstoffplatten.Devices and methods for transporting films from a stack to a laying area are known, in particular in connection with the lamination of material plates with this film in a laminating press. Films in this context mean flat paper, laminating material or the like which is suitable for being applied to a carrier material. The support material may in this case also be a film or other similar thin materials or rigid materials such. B. material plates.
Im Zuge dessen wird für eine automatisierte Vorrichtung, wie aus
Wenn auch zur damaligen Zeit den Anforderungen angemessen, so benötigt man für heutige Anwendungen Verfahren und Vorrichtungen, die flexible genug sind auf unterschiedliche Steifigkeitsgrade der Folien zu reagieren und auch noch in der Lage sind mit hoher Geschwindigkeit den Stapel zu vereinzeln und die Folien im Legebereich sicher und genau abzulegen.Although appropriate to the requirements at that time, today's applications require processes and devices which are flexible enough to respond to different levels of stiffness of the films and are also capable of high speeds To separate stacks and place the films safely and accurately in the laying area.
Insbesondere hat sich beim Stand der Technik als nachteilig erwiesen, dass die Folie zwar auf einer Seite vereinzelt wird, aber auf der anderen Seite bei der Aufnahme der Folie die Folie zu Beginn des Aufnahmevorganges erst auf den Folienstapel gedrückt wird. Auch ist von Nachteil, dass die Luft zum Unterblasen in Richtung des Legeplatzes gerichtet ist und somit zu einer Verschmutzung des Legebereiches oder der dort liegenden Substrate führt.In particular, it has proved to be disadvantageous in the prior art that the film is isolated on one side, but on the other hand, when receiving the film, the film is pressed onto the film stack at the beginning of the recording process. It is also disadvantageous that the air is directed to underblowing in the direction of the laying area and thus leads to contamination of the laying area or of the substrates lying there.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung und ein Verfahren zu schaffen, mit der es möglich ist auf unterschiedlichste Arten von Folien zu reagieren und die schnellst möglichste Taktung zu ermöglichen, die die Eigenschaften der Folie zulassen. Insbesondere sollen die bisherigen Nachteile verbessert und ein verbessertes Folienziehen ermöglicht werden.The invention has for its object to provide an apparatus and a method with which it is possible to respond to different types of films and to allow the fastest possible timing, which allow the properties of the film. In particular, the previous disadvantages are to be improved and improved film drawing made possible.
Die Vorrichtung zum Transport von Folien umfasst:
- einen Lagerplatz zur Aufnahme eines Folienstapels aus einer Vielzahl an Folien,
- eine Legeplatz zur Ablage einer Folie von dem Folienstapel,
- eine erste Saugleiste mit einem Antrieb zum Anheben einer Folie vom Folienstapel mittels Saugern und
- eine zweite Saugleiste mit einem Antrieb zum Transport einer Folie in Transportrichtung zum Legeplatz,
- Sauger zur Fixierung der Folie an den Saugleisten und
- ein Zwischentisch zwischen Lagerplatz und Legeplatz, wobei
- die erste Saugleiste geeignet ist die Folie im Wesentlichen in einem vorgegebenen Bereich an der in Transportrichtung weisenden Kante vom Folienstapel abzuheben. Die Lösung der Aufgabe für die Vorrichtung wird dadurch erreicht, dass
- der Zwischentisch mit einem Antrieb geeignet ist die angehobene Folie zumindest im Bereich zu unterfahren,
- die zweite Saugleiste geeignet ist die Folie im Wesentlichen in diesem Bereich aufzunehmen, zum Legeplatz zu transportieren und dort abzulegen.
- a storage space for receiving a film stack of a plurality of films,
- a place to lay a film from the film stack,
- a first squeegee with a drive for lifting a film from the film stack using suction cups and
- a second squeegee with a drive for transporting a film in the direction of transport to the place of laying,
- Sucker for fixing the film to the squeegee and
- an intermediate table between storage area and laying place, whereby
- the first squeegee is suitable for lifting the film from the film stack substantially in a predetermined area on the edge pointing in the direction of transport. The solution of the problem for the device is achieved in that
- the intermediate table with a drive is suitable for the raised foil at least in the area to drive under
- the second squeegee is suitable to receive the film substantially in this area, to transport to the site and store there.
Die Vorrichtung ist nun geeignet, auf unterschiedliche Arten und Weisen, insbesondere schonend für die Folien aber gleichzeitig in einer schnellen Taktrate, die Folien abzuheben und zu transportieren. Während der Positionierung und Ablage der ersten Folie mit einer zweiten Saugleiste wird die nächste Folie von der ersten Saugleiste vom Folienstapel abgehoben und eine eventuell an der zweiten Folie anhängende dritte Folie wird Gelegenheit gegeben sich von der zweiten Folie zu trennen. Dies kann mit Unterstützung von Vibrationen oder durch Anblasen der Kanten geschehen. Ist sichergestellt, meist durch Zeitablauf, dass keine weitere Folie mehr an der zweiten Folie anhängt, so kann diese unterblasen werden, damit diese beim Start des Transports durch die zweite Saugleiste nicht die nächste Folie vom Folienstapel verschiebt.The device is now suitable for lifting and transporting the films in different ways, in particular gently for the films but at the same time at a fast cycle rate. During the positioning and storage of the first film with a second squeegee, the next film is lifted from the first squeegee from the film stack and a third foil possibly attached to the second film is given the opportunity to separate from the second film. This can be done with the support of vibrations or by blowing on the edges. If it is ensured, usually through the passage of time, that no further film adheres to the second film, it can be underblown, so that it does not displace the next film from the film stack when the transport is started by the second squeegee.
Insbesondere gegenüber dem Stand der Technik bietet die vorliegende Erfindung die folgenden Vorteile:
Die Folie wird auf der Seite angehoben, auf der sie auch übernommen wird. Die angehobene Folie erhält mit dem Folienstapel keinen Kontakt mehr nach dem Anheben, sondern wird bei Bedarf auf dem verschiebbaren Zwischentisch abgelegt und dort übergeben. Es besteht somit keine Gefahr eines erneuten adhäsiven Kontakts zwischen der Folie und dem Folienstapel.In particular, compared with the prior art, the present invention offers the following advantages:
The film is lifted on the side on which it is also taken. The raised foil receives no more contact with the film stack after lifting, but is placed on demand on the sliding intermediate table and handed over there. There is thus no risk of renewed adhesive contact between the film and the film stack.
Die Richtung der Luftströmung zum Unterblasen der Folie ist in vorteilhafter Weise vom Legetisch abgewandt angeordnet. Es wird keine Verschmutzung in dieser Richtung verteilt.The direction of the air flow for underblowing the film is arranged in an advantageous manner facing away from the Legetisch. No pollution is distributed in this direction.
Die Richtung der Luftströmung entgegen der Transportrichtung der Folie kann dazu genutzt werden ein Luftpolster zu Beginn des Transportes zu etablieren, was für einen schonenden Transport und gleichzeitig zur Reinigung der Folienunterseite dient.The direction of the air flow against the transport direction of the film can be used to establish an air cushion at the beginning of the transport, which serves for a gentle transport and at the same time for cleaning the bottom of the film.
Bei einer bevorzugten Ausführungsform wird nun nicht mehr von außerhalb auf den Trennspalt zwischen Folie und Folienstapel geblasen, was mitunter dazu geführt hat, dass der Folienstapel unkontrollierbar auffächert. Sondern durch das Einfahren der Blasleiste und/oder durch die Luftleitung der Blasluft durch den Zwischentisch erfolgt eine optimale Nutzung der Blasluft zur Trennung der Folie vom Folienstapel. Durch die verbesserte Ausnutzung der Blasluft kann diese gegenüber herkömmlichen Verfahren und Vorrichtungen reduziert werden.In a preferred embodiment, it is no longer blown from the outside onto the separating gap between the film and the film stack, which has sometimes led to the film stack uncontrollably fanning out. But by the retraction of the blow bar and / or through the air line of the blown air through the intermediate table is an optimal use of the blowing air to separate the film from the film stack. By the improved utilization of the blown air this can be reduced compared to conventional methods and devices.
Weiter ist eine Anpassung der Vorrichtung auf unterschiedliche Foliengrößen nicht mehr notwendig, da an der Folienseite angehoben wird, an der die zweite Saugleiste angreift und der Folienstapel dort zentriert werden kann. Damit kann der Aufbau der Vorrichtung insgesamt einfacher gestaltet werden, da die in Transportrichtung zeigende Seite des Folienstapels immer an der gleichen Position angeordnet wird.Furthermore, an adaptation of the device to different film sizes is no longer necessary because it is lifted on the side of the film on which the second suction strip engages and the film stack can be centered there. Thus, the structure of the device can be made simpler overall, since the pointing in the direction of transport side of the film stack is always placed at the same position.
In vorteilhafter Weise sind nun eine Vielzahl an möglichen Varianten des Transportablaufes notwendig, die in Abhängigkeit von der zur Verfügung stehenden Zeit und der Materialbeschaffenheit der Folie ausgewählt werden können.Advantageously, a variety of possible variants of the transport process are now necessary, which can be selected depending on the time available and the material properties of the film.
In Vorteilhafter Weise kann die erste Saugleiste die Folie nur abheben und halten, bis die zweite Saugleiste vom Ablegen der vorherigen Folie auf dem Legeplatz zurück kommt. In einer Art fliegender Wechsel kann die zweite Saugleiste die Folie von der ersten Saugleiste im abgehobenen Zustand übernehmen, in dem diese die Folie ansaugt und anschließend die erste Stauleiste die Folie freigibt. Dies setzt natürlich eine gewisse Steifigkeit der vorhandenen Folie voraus.Advantageously, the first squeegee can only lift and hold the foil until the second squeegee comes back from depositing the previous foil on the lay. In a kind of flying change, the second squeegee can take over the film from the first squeegee in the off-hook condition in which it sucks the film and then the first batten the film releases. Of course, this requires a certain rigidity of the existing film.
Empfindlichere Folien nach dem Abheben und dem "Abtropfen lassen" einer eventuell anhängenden zusätzlichen Folie auf den Zwischentisch abgelegt werden, der in den angehobenen Bereich engefahren ist. Der Bereich nahe der Kante der Folie ist nun ausreichend gestützt und die zurückkehrende zweite Saugleiste kann dort problemlos die Folie vom Zwischentisch aufnehmen und transportieren. Sobald das Ende der gerade zu transportierenden Folie aus dem Weg ist kann die erste Saugleiste wieder damit beginnen die nächste Folie abzuheben.After the film has been lifted off and "allowed to drip off", more sensitive films can be deposited on the intermediate table, which may be in the raised area. The area near the edge of the film is now sufficiently supported and the returning second squeegee can easily pick up and transport the film from the intermediate table there. As soon as the end of the film being transported is out of the way, the first squeegee can begin to lift the next film.
Bevorzugt kann im Übrigen die Folie auf dem Zwischentisch mittels Unterdruck oder auch manuellen Klemmen gehalten werden, damit die erste Saugleiste aus dem Weg fahren kann.Preferably, moreover, the film can be held on the intermediate table by means of vacuum or manual clamps, so that the first squeegee can move out of the way.
Insbesondere ist es aber für die fliegende Übergabe oder auch für die Übergabe am Zwischentisch vorgesehen, dass die Saugleisten bzw. die Anordnung der Sauger an den Saugleisten so ausgeführt ist, dass diese gegeneinander kämmend angeordnet sind. Dies ist insbesondere bei einer fliegenden Übernahme der Folie von Vorteil. Hierzu ist besonders bevorzugt vorgesehen, dass die Sauger an den Saugleisten mittels beabstandeter Profile befestigt sind, wobei die Profile der beiden Saugleisten kämmend zueinander angeordnet sind.In particular, however, it is provided for the flying transfer or for the transfer to the intermediate table, that the squeegee or the arrangement of the sucker on the squeegee is designed so that they are arranged to mesh with each other. This is particularly advantageous in the case of a flying takeover of the film. For this purpose, it is particularly preferably provided that the suckers are attached to the suction bars by means of spaced profiles, wherein the profiles of the two suction bars are arranged in meshing relation to each other.
Alternativ oder in Kombination kann vorgesehen sein, dass an dem Zwischentisch Mittel zur der Folie, bevorzugt Unterdruckflächen, angeordnet sind. Diese sind je nach Bedarf hinsichtlich ihrer Aktivität schaltbar und in ihrer Stärke regulierbar.Alternatively or in combination, it may be provided that means for the film, preferably vacuum surfaces, are arranged on the intermediate table. Depending on their needs, these can be switched with regard to their activity and their strength can be regulated.
Alternativ oder in Kombination kann vorgesehen sein, dass eine Blasleiste zum Unterblasen der von der ersten Saugleiste angehobenen Folie angeordnet ist. Diese kann bevorzugt am Zwischentisch angeordnet sein. Alternativ oder in Kombination kann vorgesehen sein, dass beweglich zum Zwischentisch respektive beweglich mit dem Zwiscentisch angeordnet ist.Alternatively or in combination, it may be provided that a blow bar is arranged for underblowing the film lifted by the first suction strip. This can preferably be arranged on the intermediate table. Alternatively or in combination it can be provided that is movably arranged to the intermediate table respectively movable with the Zwiscentisch.
Bevorzugt ist Blasleiste separat ausgebildet und unterbläst die Folie. Der eingefahrene Zwischentisch kann dabei als Luftführung dienen und für eine optimale Einleitung der Blasluft zwischen die Folie und den Folienstapel sorgen. Der Zwischentisch kann aber auch in die Blasleiste integriert sein oder vice versa, wie im Ausführungsbeispiel gezeigt. Bevorzugt ist vorgesehen, dass eine Blasleiste, ein als Blasleiste ausgebildeter Zwischentisch, ein Zwischentisch und/oder ein Zwischentisch mit einer Blasleiste zwischen angehobene Folie und Folienstapel einfährt und für die "mechanische und/oder pneumatische Trennung" sorgt.Preferably, the blowing strip is formed separately and underpins the film. The retracted intermediate table can serve as an air guide and ensure optimum introduction of the blowing air between the film and the film stack. The intermediate table can also be integrated in the blow bar or vice versa, as shown in the embodiment. It is preferably provided that a blow bar, an intermediate table formed as a blow bar, an intermediate table and / or an intermediate table with a blow bar between raised foil and film stack enters and provides for the "mechanical and / or pneumatic separation".
Alternativ oder in Kombination kann vorgesehen sein, dass die Sauger mit einer pneumatischen Unterdruckeinrichtung und die Blasleiste mit einer pneumatischen Druckvorrichtung wirkverbunden sind.Alternatively or in combination can be provided that the suction with a pneumatic vacuum device and the blow bar with a pneumatic pressure device are operatively connected.
Die Lösung für das Verfahren zum Transport von Folien von einem Folienstapel zu einem Legeplatz, wobei eine erste Folie von dem Folienstapel mit einer ersten Saugleiste abgehoben und anschließend von einer zweiten Saugleiste auf dem Legeplatz abgelegt wird, besteht im Wesentlichen darin, dass die erste Folie an einem vorgegebenen Bereich an der in Transportrichtung weisenden Seite von der Saugleiste abgehoben wird und anschließend die Folie im Wesentlichen in einem in Transportrichtung Bereich in Transportrichtung von der zweiten Saugleiste aufgenommen und zum Legeplatz transportiert und dort abgelegt wird, wobei die abgehobene Folie 1 nach dem Abheben von einem Zwischentisch entgegen der Transportrichtung unterfahren wird.The solution for the method for transporting films from a film stack to a laying area, wherein a first film is lifted from the film stack with a first squeegee and then deposited by a second squeegee on the shelf, consists essentially in that the first film a predetermined area on the side pointing in the direction of transport is lifted from the squeegee and then the film is substantially taken in a direction of transport in the transport direction of the second squeegee and transported to the site and stored there, the lifted film 1 after lifting off a sub-table is approached against the transport direction.
Im Sinne des "Unterfahrens" ist es nicht unbedingt notwendig, dass der Zwischentisch die Folie berührend oder unterstützend unterfährt. Vielmehr ist vorgesehen, dass die Folie anschließend, bei einer nicht fliegenden Übergabe, von der ersten Saugleiste auf den Zwischentisch abgelegt wird. Eine am Zwischentische angeordnete oder eigenständige Blasleiste kann dann die Folie unterblasen. Bevorzugt wird die Blasleiste mit dem Zwischentisch zusammenwirkend angeordnet sein, insbesondere bevorzugt einstückig. Alternativ oder in Kombination kann der Zwischentisch die Luftströmung aus der Blasleiste leiten.In the sense of "driving under", it is not absolutely necessary that the intermediate table underlies the film touching or supportive. Rather, it is provided that the film is then stored in a non-flying transfer, from the first squeegee to the intermediate table. An arranged on the intermediate table or stand-alone blow bar can then inflate the film. Preferably, the blow bar will be arranged cooperatively with the intermediate table, in particular preferably in one piece. Alternatively or in combination, the intermediate table can direct the flow of air from the blow bar.
Bevorzugt wird die erste Saugleiste mit dem Abheben der nächsten Folie vom Folienstapel beginnen, wenn die von der Transportrichtung entgegengesetzte Kante der ersten Folie den Folienstapel verlassen hat.Preferably, the first squeegee starts with the lifting of the next film from the film stack when the opposite of the transport direction edge of the first film has left the film stack.
Alternativ oder in Kombination kann die erste Saugleiste die Folie an die zweite Saugleiste übergeben. Bevorzugt kann zusätzlich vorgesehen, dass die zweite Saugleiste die Folie von der ersten Saugleiste und/oder vom Zwischentisch übernimmt.Alternatively or in combination, the first squeegee may transfer the film to the second squeegee. Preferably, it may additionally be provided that the second suction strip takes over the film from the first suction strip and / or from the intermediate table.
Alternativ oder in Kombination können die beiden Saugleisten respektive die bevorzugt an beabstandeten Profilen angeordneten Sauger während der Weitergabe der Folie kämmen.Alternatively or in combination, the two suction strips or the suction pads, which are preferably arranged on spaced profiles, can mesh during the transfer of the film.
Alternativ oder in Kombination kann die Folie auf dem Zwischentisch gehalten wird, bevorzugt mit Unterdruck, der ersten Saugleiste und/oder mit mechanischen Mitteln.Alternatively or in combination, the film may be held on the intermediate table, preferably with negative pressure, the first squeegee and / or by mechanical means.
Alternativ oder in Kombination kann die Folie nach dem Aufheben vom Folienstapel mittels einer Blasleiste unterblasen werden, bevorzugt mit einer Blasleiste, besonders bevorzugt mit einer beweglichen und/oder am Zwischentisch angeordneten Blasleiste.Alternatively or in combination, the film can be blown after being lifted from the film stack by means of a blow bar, preferably with a blow bar, more preferably with a movable and / or arranged on the intermediate table blowing bar.
Alternativ oder in Kombination kann der Zwischentisch in der Höhe verfahren wird, bevorzugt zur Herstellung des Kontaktes mit der an der ersten Saugleiste gehaltenen Folie.Alternatively or in combination, the intermediate table can be moved in height, preferably for producing the contact with the film held on the first suction strip.
Die Vorrichtung kann eigenständig vom Verfahren betrieben werden, ist aber besonders bevorzugt zur Durchführung des Verfahrens geeignet.The device can be operated independently by the method, but is particularly preferably suitable for carrying out the method.
Weitere vorteilhafte und zweckmäßige Ausgestaltungen der Erfindung sind nachstehend anhand der Zeichnung näher beschrieben und in den Unteransprüchen angegeben.Further advantageous and expedient embodiments of the invention are described below with reference to the drawing and specified in the dependent claims.

Alternativ kann zu dem hier dargestellten Legetisch auch ein Transportband vorgesehen sein, auf dem direkt oder auf ein dort angeordnetes Substrat (Werkstoffplatte) aufgelegt wird.Alternatively, to the laying table shown here, a conveyor belt may be provided, is placed on the directly or on a arranged there substrate (material plate).
Die zweite Saugleiste 6, hauptsächlich zuständig für den Transport der Folie 1, wird an einer Traverse 15 mittels eines geeigneten Antriebes beweglich angeordnet sein. Die erste Saugleiste 3 kann ebenfalls über diese Traverse 15 oder ein eigenes Portal bewegbar angeordnet sein. Für die Bewegungen entlang der eingezeichneten Pfeile an beiden Saugleisten 3, 6 und dem Zwischentisch 13 sind ebenfalls geeignete aber nicht weiter illustrierte Antriebe vorgesehen.

In vorteilhafter Weise vermag nun die Vorrichtung in einer hohen Frequenz Folien 1 vom Folienstapel 2 zu vereinzeln und zu transportieren. Die neue Vorrichtung ermöglicht die Folienseparierung (Anheben und falls notwendig Abtropfen lassen einer weiteren Folie) zeitgleich mit dem Transport einer Folie 1 auf den Legeplatz 12. Dabei setzt die erste heb- und senkbare Saugleiste 3 nahe der Folienstapelkante in einem Bereich 17 auf, der in Transportrichtung 9 weist, saugt die oberste Folie 1 an und hebt diese vom Folienstapel 2 ab.
