Description

Technisches Gebiettechnical field

Die Erfindung betrifft eine Kantenbandkassette für Kantenbänder.The invention relates to an edging tape cassette for edging tapes.

Bei der Herstellung von plattenförmigen Werkstücken, insbesondere aus Holz oder Holzersatzwerkstoffen, wie Faserplatten, Spanplatten, HDF-Platten, MDF-Platten, Laminaten oder ähnlichem, ist es regelmäßig so, dass bei der Verarbeitung der plattenförmigen Werkstücke die Schmalseiten derselben mit streifenförmigen Kaschierungsmaterialien, sogenannten Kantenbändern, versehen werden. Da derartige plattenförmige Werkstücke insbesondere in Bereichen verwendet werden, in denen die optische Erscheinung eine große Rolle spielt, wie vor allem beim Bau von Möbeln, aber auch bei Türen, Innenverkleidungen von Gebäuden und dergl., existieren eine Vielzahl unterschiedlicher Kantenbänder, um unterschiedliche dekorative und/oder funktionelle Ausgestaltungen der resultierenden plattenförmigen Werkstücke und der ggf. daraus weiter hergestellten Produkte zu ermöglichen.In the production of panel-shaped workpieces, in particular from wood or wood substitute materials such as fiberboard, chipboard, HDF panels, MDF panels, laminates or the like, it is regularly the case that when processing the panel-shaped workpieces, the narrow sides of the same with strip-shaped laminating materials, so-called edge bands, are provided. Since such plate-shaped workpieces are used in particular in areas where the visual appearance plays a major role, such as in the construction of furniture, but also in doors, interior paneling of buildings and the like., There are a variety of different edge bands to different decorative and / or to enable functional configurations of the resulting plate-shaped workpieces and the products that may be further manufactured from them.

Die Kantenbänder müssen an den jeweiligen Produktionseinrichtungen bereitgestellt werden, wobei abhängig von der jeweils geplanten Produktion eine Vielzahl unterschiedlicher Kantenbänder bereitgehalten werden muss. Aufgrund der Tatsache, dass die zu kaschierenden Schmalseiten das gesamte Werkstück umspannen, wird ein verhältnismäßig großer Längenabschnitt pro Werkstück benötigt, d.h. im Rahmen einer modernen und leistungsfähigen Produktion werden große Mengen der Kantenbänder verarbeitet. Die Kantenbandhersteller stellen die Kantenbänder für gewöhnlich in Form von spiralförmig aufgewickelten Gebinden zur Verfügung. Die Kantenbänder sind dann regelmäßig mit Hilfsmitteln, wie Bändern, die die Wicklungen der spiralförmigen Gebinde zusammenhalten, gesichert und werden in üblichen Verpackungen, wie Schachteln oder Kartons oder auf Paletten angeliefert. Es ist auch möglich, dass die Kantenbänder auf - in der Regel ringförmige - Wickelkerne aufgewickelt werden. Diese verleihen dem Gebinde zusätzliche Stabilität, was insbesondere bei dünnen Kantenbändern und/oder Kantenbändern aus Papier vorteilhaft ist.The edge bands must be made available at the respective production facilities, with a large number of different edge bands having to be kept available depending on the production planned in each case. Due to the fact that the narrow sides to be laminated span the entire workpiece, a relatively large section of length per workpiece is required, ie large quantities of the edgebands are processed within the framework of modern and efficient production. The edge band manufacturers usually provide the edge bands in the form of spirally wound bundles. The edge bands are then regularly secured with aids such as bands that hold the windings of the spiral bundles together and are delivered in conventional packaging such as boxes or cartons or on pallets. It is also possible for the edge bands to be wound up on—usually ring-shaped—winding cores. These give the container additional stability, which is particularly advantageous for thin edge bands and/or edge bands made of paper.

In der Praxis ist es nun erforderlich, die Produktionseinrichtungen im laufenden Betrieb permanent mit neuen Kantenbändern zu bestücken. In der Praxis stellen die spiralförmigen Wick-lungen hierbei ein nicht unerhebliches Problem im Bezug auf deren Handling dar. Werden diese aus den Schachteln ausgepackt bzw. die Fixierbänder, die ggf. die Wicklung zusammenhalten, gelöst, so kommt es regelmäßig vor, dass sich die Kantenbänder abwickeln. Diese müssen dann händisch und regelmäßig unter Zeitdruck neu aufgewickelt und der Produktionseinrichtung zugeführt werden. In der Praxis entsteht hierdurch ein nicht unerheblicher personeller Aufwand, schlimmstenfalls kommt es sogar zu Betriebsunterbrechungen, wenn ein versehentlich abgewickeltes Kantenband nicht schnell genug durch ein noch aufgewickeltes ersetzt oder wieder aufgewickelt werden kann.In practice, it is now necessary to continuously equip the production facilities with new edgebands during operation. In practice, the spiral windings present a not inconsiderable problem in terms of handling Unwind edge bands. These then have to be rewound manually and regularly under time pressure and fed to the production facility. In practice, this results in a not inconsiderable amount of personnel expenditure, and in the worst case there are even operational interruptions if an edge band that has accidentally been unwound cannot be replaced quickly enough by one that is still wound up or can be wound up again.

Stand der TechnikState of the art

Es hat daher bereits in der Vergangenheit Überlegungen gegeben, das Handling der Kantenbänder zu vereinfachen bzw. zu automatisieren. Hierbei sind beispielsweise voll automatisierte und/oder auf Kassetten basierende Systeme entwickelt worden. Solche Systeme sind beispielsweise in der EP 1 860 593 B1 oder der EP 1 860 596 B1 offenbart. EP 1 862 949 A2 beschreibt eine Vorrichtung nach dem Oberbegriff des Anspruchs 1.In the past, there have therefore already been considerations of simplifying the handling of the edgebands or to automate. For example, fully automated and/or cassette-based systems have been developed here. Such systems are for example in the EP 1 860 593 B1 or the EP 1 860 596 B1 disclosed. EP 1 862 949 A2 describes a device according to the preamble of claim 1.

Nachteilig an den bisher bekannten Systemen ist, dass sie zum einen vergleichsweise komplex und damit teuer sind. Zum ande-ren wird das Problem der Bestückung lediglich verlagert, d.h. die Handling-Probleme treten nicht mehr direkt an der Beschickungsvorrichtung auf, aber beispielsweise beim Befüllen der entsprechenden Kassetten.A disadvantage of the previously known systems is that they are comparatively complex and therefore expensive. On the other hand, the problem of loading is only shifted, i.e. the handling problems no longer occur directly at the loading device, but for example when filling the corresponding cassettes.

Die ErfindungThe invention

Der Erfindung liegt daher die Aufgabe zugrunde, eine Kantenbandkassette bereitzustellen, die eine Lösung für das vorstehend beschriebene Handling-Problem bei der Verarbeitung von Kantenbändern ermöglicht.The invention is therefore based on the object of providing an edging tape cassette which enables a solution to the handling problem described above when processing edging tapes.

Die Aufgabe wird gelöst durch eine Katenbandkassette mit den Merkmalen des Anspruchs 1. Die Merkmale der abhängigen Ansprüche betreffen vorteilhafte Ausführungsformen.The object is achieved by a cat tape cassette having the features of claim 1. The features of the dependent claims relate to advantageous embodiments.

Die erfindungsgemäße Kantenbandkassette zur Aufnahme von Kantenbändern weist ein Kassettengehäuse auf, in welchem ein Wickelkern angeordnet ist, welcher ein Kantenband fixiert hält. Das Kantenband selbst liegt darin als Gebinde oder Wickel in einer zu einer Rolle aufgewickelten Form vor. Die Kantenbandkassette weist erfindungsgemäß zusätzlich zum Wickelkern ein im Kassettengehäuse drehbar gelagertes Aufnahmeelement auf, welches in der Kantenbandkassette drehbar gelagert ist und an dem der Wickelkern, insbesondere lösbar, angebracht ist.The edging tape cassette according to the invention for accommodating edging tapes has a cassette housing in which a winding core is arranged, which keeps an edging tape fixed. The edging tape itself is in the form of a bundle or coil in a form wound up into a roll. According to the invention, the edging tape cassette has, in addition to the winding core, a receiving element which is rotatably mounted in the cassette housing and which is in the edging tape cassette is rotatably mounted and on which the winding core, in particular releasably attached.

Durch das Anbringen des Wickelkerns an dem Aufnahmeelement kann eine sehr einfache Bestückung des Aufnahmeelements mit dem Kantenband erfolgen. Optional können die bereits auf den Wickelkern aufgewickelten Kantenbänder dann durch eine einfache Maßnahme einseitig am Aufnahmeelement angebracht werden. Zudem kann das Aufnahmeelement als zusätzlicher Schwungkörper dienen, welcher bei der Rotation (d.h. beim Aufwickeln oder Abwickeln des Kantenbandes) in Drehung versetzt wird.By attaching the winding core to the receiving element, it is very easy to equip the receiving element with the edge band. Optionally, the edge bands that have already been wound onto the winding core can then be attached to the receiving element on one side by a simple measure. In addition, the receiving element can serve as an additional flywheel, which is set in rotation during rotation (i.e. when winding or unwinding the edgeband).

Erfindungsgemäß ist vorgesehen, dass der Wickelkern drehfest mit dem Aufnahmeelement verbunden ist. Hierbei erstreckt sich zumindest ein Teil des Aufnahmeelements von dessen Drehachse aus radial über die radiale Erstreckung des Wickelkerns hinaus. Bevorzugt kann dieser sich hinaus erstreckende Teil dafür eingesetzt werden, dass das Gebinde zumindest teilweise am Aufnahmeelement anliegt. Auf diese Weise kann beispielsweise beim Wiederaufwickeln des Kantenbandes eine Anlage geschaffen werden, die dabei hilft, dass das Band beim Aufwickeln nicht seitlich verrutschen kann.According to the invention it is provided that the winding core is non-rotatably connected to the receiving element. In this case, at least part of the receiving element extends radially from its axis of rotation beyond the radial extent of the winding core. Preferably, this part extending out can be used to ensure that the container rests at least partially on the receiving element. In this way, for example, when rewinding the edging tape, a system can be created that helps prevent the tape from slipping sideways when it is being wound up.

Weiter kann der Wickelkern lediglich an einer Seite des Aufnahmeelements angebracht sein. Auf diese Weise ist eine einfache Bestückung des Aufnahmeelements bzw. der Kantenbandkassette möglich. Außerdem braucht das Aufnahmeelement lediglich einseitig am Gehäuse der Kantenbandkassette gelagert zu sein.Furthermore, the winding core can only be attached to one side of the receiving element. In this way, it is possible to easily equip the receiving element or the edging tape cassette. In addition, the receiving element only needs to be mounted on one side on the housing of the edging tape cassette.

Besonders bevorzugt ist vorgesehen, dass das Aufnahmeelement einen, vorzugsweise zumindest im Wesentlichen rotationssymmetrischen, zumindest im Wesentlichen scheibenförmigen Grundkörper aufweist. Dieser Grundkörper ist drehbar im Kassettengehäuse gelagert und kann dann beim Drehen als Schwungmasse dienen. Zudem hat die scheibenförmige Ausgestaltung den Vorteil, dass diese auch durch zusätzliche Antriebsmittel, beispielsweise Antriebsräder oder Antriebsscheiben, in Drehung versetzt werden kann. Diese Antriebsmittel müssen dann nicht an der Drehachse angreifen, sondern können beispielsweise im Verhältnis zum Aufnahmeelement tangential angreifend angeordnet werden.Provision is particularly preferably made for the receiving element to have one, preferably at least substantially has a rotationally symmetrical, at least substantially disc-shaped body. This base body is rotatably mounted in the cassette housing and can then serve as a flywheel when rotating. In addition, the disk-shaped configuration has the advantage that it can also be set in rotation by additional drive means, for example drive wheels or drive disks. These drive means then do not have to act on the axis of rotation, but can be arranged, for example, acting tangentially in relation to the receiving element.

Nach einer weiteren Ausführungsform der vorliegenden Erfindung kann der Wickelkern als Innenklemmeinrichtung zum Fixieren des aufgewickelten Kantenbandes ausgebildet sein. Die Innenklemmeinrichtung ist dazu ausgebildet, nach außen gerichtete Kräfte auf eine nach innen gerichtete Fläche des Gebindes auszuüben. Diese nach innen gerichtete Fläche des Gebindes kann durch die innerste Wicklung des Kantenbandes gebildet sein, es kann sich aber auch um eine nach innen gerichtete Fläche eines Wickelkerns, auf den das Kantenband gewickelt ist, handeln.According to a further embodiment of the present invention, the winding core can be designed as an internal clamping device for fixing the wound edge band. The internal clamping device is designed to exert outwardly directed forces on an inwardly directed surface of the container. This inwardly directed surface of the pack can be formed by the innermost winding of the edge band, but it can also be an inwardly directed surface of a winding core onto which the edge band is wound.

Es hat sich gezeigt, dass es möglich ist, mit einer derartigen Innenklemmeinrichtung ein aufgewickeltes Kantenband sicher am Aufnahmeelement zu fixieren. Die Innenklemmeinrichtung ist insbesondere dadurch gekennzeichnet, dass sie nach außen gerichtete Kräfte auf eine nach innen gerichtete Fläche des Gebindes ausüben kann.It has been shown that it is possible to use such an internal clamping device to securely fix a wound edge band to the receiving element. The internal clamping device is characterized in particular in that it can exert outwardly directed forces on an inwardly directed surface of the container.

Weiterhin kann eine solche Innenklemmeinrichtung als vorzugsweise rein mechanische Einrichtung in einfacher und kostengünstiger Weise realisiert werden. Hierdurch ist es möglich, eine große Anzahl an Aufnahmeelementen bereit zu stellen. Die in aufgewickelter Form angelieferten Kantenbänder können dann mit einigem zeitlichen Vorlauf vor ihrer Verwendung mit den Innenklemmeinrichtungen an den Aufnahmeelementen fixiert werden. Danach ist es möglich, die fixierten Kantenbänder mit den Aufnahmeelementen gemeinsam an den Produktionseinrichtungen in dem Moment bereit zu stellen, in dem sie tatsächlich benötigt werden. Durch die sichere Fixierung des Kantenbands am Aufnahmeelement wird dieser kritische Schritt im Handling des Kantenbandes zum einen vereinfacht und zum anderen sicher im Hinblick auf eine ungewollte Abwicklung des Kantenbandes gestaltet.Furthermore, such an internal clamping device as a preferably purely mechanical device in a simple and be implemented in a cost-effective manner. This makes it possible to provide a large number of receiving elements. The edge bands, which are delivered in coiled form, can then be fixed to the receiving elements with the internal clamping devices some time before they are used. It is then possible to provide the fixed edge bands together with the receiving elements at the production facilities at the moment when they are actually needed. By securely fixing the edging tape to the receiving element, this critical step in the handling of the edging tape is simplified on the one hand and designed securely with regard to unintentional unwinding of the edging tape on the other.

Hierbei ist es weiterhin vorteilhaft, wenn das Aufnahmeelement einen zumindest im Wesentlichen scheibenförmigen Grundkörper aufweist. Der scheibenförmige Grundkörper erleichtert die Bestückung des Aufnahmeelements mit dem Kantenband. Das Aufnahmeelement kann dann, vorzugsweise mit nach unten weisendem Grundkörper und nach oben weisender Innenklemmeinrichtung, an einem geeigneten Arbeitsplatz bereitgelegt werden. Das in aufgewickelter Form angelieferte Kantenband kann auf dem Grundkörper um die Innenklemmeinrichtung platziert werden. Etwaige Verpackungsmaterialien und Fixierbänder können dann ohne die Gefahr eines ungewollten Abwickelns des auf dem Grundkörper ruhenden Kantenbandes entfernt werden. Anschließend wird das auf dem Grundkörper ruhende Kantenband mit der Innenklemmeinrichtung fixiert. Der so gebildete Verbund aus dem Kantenband und dem Aufnahmeelement ist dann sicher handhabbar und kann unmittelbar einer Produktionseinrichtung zugeführt oder bis zu seiner Verwendung zwischengelagert werden.It is also advantageous here if the receiving element has an at least essentially disc-shaped base body. The disc-shaped base body makes it easier to equip the receiving element with the edgeband. The receiving element can then be placed ready at a suitable work station, preferably with the base body pointing downwards and the inner clamping device pointing upwards. The edging tape, which is delivered in a coiled form, can be placed on the base body around the internal clamping device. Any packaging materials and fixing tapes can then be removed without the risk of the edge tape resting on the base body unwinding unintentionally. The edge band resting on the base body is then fixed with the internal clamping device. The composite formed in this way from the edging strip and the receiving element can then be handled safely and can immediately be used be supplied to the production facility or stored temporarily until it is used.

Vorzugsweise ist der Grundkörper zumindest im Wesentlichen rotationssymmetrisch ausgeführt. Die rotationssymmetrische Ausführung des Grundkörpers - und insbesondere des Aufnahmeelements - erleichtert es, das Aufnahmeelement drehbar bzw. rotierbar in der Kantenbandkassette aufzunehmen. Die rotierbare Aufnahme ist deswegen von Vorteil, da eine möglichst ungehinderte Rotation des Aufnahmeelements das Abwickeln des Kantenbands während der Produktion erleichtert.The base body is preferably designed to be at least essentially rotationally symmetrical. The rotationally symmetrical design of the base body - and in particular of the receiving element - makes it easier to receive the receiving element rotatably or rotatably in the edging tape cassette. The rotatable holder is advantageous because the unhindered rotation of the holder element facilitates the unwinding of the edge band during production.

Vorteilhafterweise weist das Aufnahmeelement für dessen rotierbare Lagerung am Gehäuse der Kantenbandkassette ein entsprechendes Lagerungselement auf. Hierbei kann es sich beispielsweise um eine - vorzugsweise zentrisch am Aufnahmeelement angeordnete - Achse handeln. Für eine sichere rotierbare Lagerung des Aufnahmeelements ist es besonders vorteilhaft, wenn dieses zwei Lagerungselemente auf einander abgewandten Seiten des Aufnahmeelements aufweist.The receiving element advantageously has a corresponding bearing element for its rotatable bearing on the housing of the edging tape cassette. This can be, for example, an axis—preferably arranged centrally on the receiving element. For a secure, rotatable mounting of the receiving element, it is particularly advantageous if it has two mounting elements on opposite sides of the receiving element.

Die Innenklemmeinrichtung des Aufnahmeelements weist bevorzugt eine Mehrzahl Spannelemente auf. Diese sind zur Fixierung des aufgewickelten Kantenbands gegen die nach innen gerichtete Fläche des Gebindes des Kantenbands verspannbar. Hierbei kann es von Vorteil sein, die Spannelemente austauschbar zu gestalten. Auf diese Weise kann unterschiedlichen Innendurchmessern des Gebindes des aufgewickelten Kantenbandes durch die Auswahl entsprechender Spannelemente Rechnung getragen werden. Ebenfalls ist die Verwendung jeweils passender Spannelemente für unterschiedliche Breiten des Kantenbandes möglich. Bevorzugt wirken die Spannelemente hierbei nach Art von Spannbacken auf das Gebinde des aufgewickelten Kantenbands.The inner clamping device of the receiving element preferably has a plurality of clamping elements. These can be braced against the inwardly directed surface of the container of the edge band in order to fix the wound edge band. It can be advantageous here to make the clamping elements interchangeable. In this way, different inner diameters of the bundle of the wound edge band can be taken into account by selecting appropriate clamping elements. The use of suitable clamping elements is also important possible for different widths of the edgeband. The clamping elements preferably act on the bundle of the wound edge band in the manner of clamping jaws.

Vorzugsweise sind die Spannelemente an dem Grundkörper zum Fixieren des Kantenbands entlang einer Spannrichtung verschieblich geführt. Die Spannrichtung weist dabei zumindest eine radiale Komponente bezogen auf die scheibenförmige Erstreckung des Grundkörpers auf. Hierdurch wird es ermöglicht, die Spannelemente auf die nach innen gerichtete Fläche des Gebindes des Kantenbands zuzubewegen, um dieses zu fixieren. Bevorzugt ist die Spannrichtung zumindest in radialer Richtung bezogen auf die scheibenförmige Erstreckung des Grundkörpers orientiert. Eine solche, zumindest im Wesentlichen radiale Orientierung bewegt die Spannelemente in direkter Richtung auf die nach innen gerichtete Fläche zu, wenn das Gebinde des Kantenbands mit der Innenklemmeinrichtung fixiert wird.The tensioning elements are preferably guided displaceably on the base body for fixing the edgeband along a tensioning direction. The clamping direction has at least one radial component based on the disk-shaped extension of the base body. This makes it possible to move the clamping elements towards the inwardly directed surface of the container of the edge band in order to fix it. The clamping direction is preferably oriented at least in the radial direction in relation to the disk-shaped extension of the base body. Such an at least essentially radial orientation moves the clamping elements in a direct direction towards the inwardly directed surface when the container of the edge band is fixed with the inner clamping device.

Besonders bevorzugt weist die Innenklemmeinrichtung ein drehbares Drehelement zum Fixieren des Gebindes des Kantenbands auf. In diesem Zusammenhang ist die Innenklemmeinrichtung derart gestaltet, dass eine Drehung des Drehelements relativ zu dem Grundkörper das Fixieren des Kantenbands bewirkt. Bevorzugt ist das Drehelement hierbei zentrisch am scheibenförmigen Grundkörper angeordnet. Durch diese zentrische Anordnung kann das Drehelement seine nach außen gerichtete Spannwirkung gleichmäßig über seinen Umfang verteilt entfalten. Nach einer bevorzugten Ausführungsform werden durch die Drehung des Drehelements die Spannelemente entlang ihrer jeweiligen Spannrichtung verschoben. Dies kann beispielsweise dadurch bewerkstelligt werden, dass das Drehelement bei seiner Drehung an, vorzugsweise spiralförmig angeordneten, Gleitflächen an den Spannelementen abgleitet, wobei diese durch die, insbesondere spiralförmige, Gestaltung der Gleitflächen nach außen und damit gegen die nach innen weisende Fläche des Gebindes verschoben werden.The internal clamping device particularly preferably has a rotatable rotary element for fixing the bundle of edge bands. In this context, the inner clamping device is designed in such a way that a rotation of the rotary element relative to the base body causes the edge band to be fixed in place. In this case, the rotary element is preferably arranged centrally on the disc-shaped base body. Due to this central arrangement, the rotary element can unfold its outwardly directed clamping effect, distributed evenly over its circumference. According to a preferred embodiment, the clamping elements are displaced along their respective clamping direction by the rotation of the rotating element. This can be done, for example that the rotary element slides off, preferably spirally arranged, sliding surfaces on the clamping elements during its rotation, whereby these are pushed outwards by the, in particular spiral, design of the sliding surfaces and thus against the inward-facing surface of the container.

Der scheibenförmige Grundkörper weist bevorzugt ein erstes Verbindungselement auf. Ebenfalls bevorzugt weist das Drehelement ein zweites Verbindungselement auf. Das erste und das zweite Verbindungselement dienen zum Verbinden eines Werkzeugs zum Fixieren des Kantenbandes mit dem Aufnahmeelement. Hierdurch müssen keine, ggf. beim Handling des Kantenbands störenden, Bedienelemente an dem Aufnahmeelement vorgesehen werden. Für die Betätigung der Innenklemmeinrichtung reicht es, temporär ein Werkzeug mit dem Aufnahmeelement zu verbinden, insbesondere um die Verdrehung des Drehelements zu bewirken. Hierdurch kann das Werkzeug entsprechende Ausmaße, wie beispielsweise eine entsprechende Hebellänge, aufweisen, um eine sichere Verklemmung mit ausreichenden Klemmkräften zu gewährleisten. Die hierfür in vorteilhafter Weise zur Erzeugung ausreichender Kräfte verwendeten Hebellängen bedingen ggf. eine Größe des Werkzeugs, die bei einer festen Verbindung mit dem Aufnahmeelement beim Aufbringen des Kantenbandes auf die Innenklemmeinrichtung hinderlich wäre. Verbindungselemente zum temporären Anbringen des Werkzeugs erleichtern somit wesentlich das Handling.The disc-shaped base body preferably has a first connecting element. The rotating element also preferably has a second connecting element. The first and the second connecting element are used to connect a tool for fixing the edge band to the receiving element. As a result, there is no need to provide operating elements on the receiving element that might interfere with the handling of the edging strip. To actuate the inner clamping device, it is sufficient to temporarily connect a tool to the receiving element, in particular in order to rotate the rotary element. As a result, the tool can have appropriate dimensions, such as an appropriate lever length, in order to ensure secure clamping with sufficient clamping forces. The lever lengths used in an advantageous manner for generating sufficient forces may require a size of the tool that would be a hindrance in the case of a fixed connection with the receiving element when the edge band is applied to the inner clamping device. Connection elements for temporarily attaching the tool thus make handling much easier.

Bevorzugt weist das Aufnahmeelement ein Fixierelement zum Fixieren des Drehelements relativ zum Grundkörper auf. Ein solches Fixierelement ermöglicht es, die Fixierung des Gebindes des Kantenbandes durch die Innenklemmeinrichtung wirkungsvoll gegen ein versehentliches Lösen zu sichern. Das Fixierelement kann dabei in vorteilhafter Weise derart gestaltet sein, dass es eine kraftschlüssige Verhinderung einer Drehung des Drehelements relativ zum Grundkörper herbeiführt. Dies kann beispielsweise mit einer Schraube geschehen, die zum Fixieren des Drehelements eine reibschlüssige Verbindung zwischen dem Drehelement und dem Grundkörper erzeugt.The receiving element preferably has a fixing element for fixing the rotary element relative to the base body. Such a fixing element makes it possible to fix the container of the edgeband by the inner clamping device effectively secured against accidental loosening. In this case, the fixing element can advantageously be designed in such a way that it brings about a force-locking prevention of rotation of the rotary element relative to the base body. This can be done, for example, with a screw that creates a frictional connection between the rotary element and the base body to fix the rotary element.

Nach einer bevorzugten Ausführungsform ist vorgesehen, dass die Kantenbandkassette eine Bremseinrichtung zum Abbremsen einer Rotation des Aufnahmeelements und/oder einer Feststelleinrichtung zum Blockieren der Rotation des Aufnahmeelements und/oder eine Beschleunigungseinrichtung zum Beschleunigen einer Rotation des Aufnahmeelements, die vorzugsweise im Bereich des äußeren Randes des Grundkörpers an den Grundkörper angreift, aufweist.According to a preferred embodiment, it is provided that the edge tape cassette has a braking device for braking a rotation of the receiving element and/or a locking device for blocking the rotation of the receiving element and/or an acceleration device for accelerating a rotation of the receiving element, which is preferably located in the area of the outer edge of the base body engages the body has.

Eine Bremseinrichtung bietet den Vorteil, dass durch sie das Kantenband gestrafft werden kann. Dies stabilisiert zum einen die Fixierung des Kantenbandes auf dem Wickelkern, zum anderen wirkt sich die Straffung des Kantenbands vorteilhaft auf die weitere Be- oder Verarbeitung des Kantenbands aus. Der besondere Vorteil einer solchen Bremseinrichtung im Zusammenhang mit den erfindungsgemäßen Aufnahmeelementen ist, dass die Bremseinrichtung direkt am Aufnahmeelement angreifen kann. Aufgrund der Unterschiede in den mechanischen Eigenschaften des Kantenbands sind Bremseinrichtungen, die direkt auf ein Kantenband wirken, vergleichsweise problematisch. Bei einer erfindungsgemäßen Kantenbandkassette kann die Bremseinrichtung dagegen vorteilhaft auf das Aufnahmeelement und damit indirekt auf das Kantenband wirken. So kann beispielsweise die Bremseinrichtung nach Art einer Scheibenbremse ausgeführt sein und an dem Grundkörper angreifen. Hierdurch lässt sich eine zuverlässige und zugleich einfache Bremseinrichtung realisieren.A braking device offers the advantage that it can tighten the edgeband. On the one hand, this stabilizes the fixing of the edging tape on the winding core, and on the other hand, the tightening of the edging tape has an advantageous effect on the further treatment or processing of the edging tape. The particular advantage of such a braking device in connection with the receiving elements according to the invention is that the braking device can act directly on the receiving element. Due to the differences in the mechanical properties of the edgeband, braking devices that act directly on an edgeband are comparatively problematic. In an edge band cassette according to the invention, on the other hand, the braking device can advantageously act on the receiving element and thus indirectly on the edge band. So For example, the braking device can be designed in the manner of a disk brake and act on the base body. This allows a reliable and at the same time simple braking device to be implemented.

Ebenso kann dieselbe Einrichtung oder eine zusätzliche Einrichtung auch zum Feststellen bzw. Fixieren des Aufnahmeelementes in der Kantenbandkassette vorgesehen sein. Dies eignet sich insbesondere dann, wenn die Kantenbandkassette transportiert werden soll, sodass sich das Kantenband nicht unbeabsichtigt abwickeln kann.Likewise, the same device or an additional device can also be provided for determining or fixing the receiving element in the edge band cassette. This is particularly useful when the edge band cassette is to be transported so that the edge band cannot unroll unintentionally.

Ebenso vorteilhaft ist es, wenn die Kantenbandkassette eine Beschleunigungseinrichtung zum Beschleunigen einer Rotation des Aufnahmeelements aufweist. Eine solche Beschleunigungseinrichtung kann beispielsweise dadurch realisiert sein, dass eine Reibrolle am äußeren Rand des Aufnahmeelements bzw. dessen Grundkörpers angreift. Auf diese Weise können die zur Beschleunigung notwendigen Kräfte als Reibkräfte übertragen werden. Alternativ ist es aber auch möglich, eine Verzahnung zwischen dem Aufnahmeelement bzw. dem Grundkörper und der Beschleunigungseinrichtung vorzusehen.It is just as advantageous if the edgeband cassette has an acceleration device for accelerating a rotation of the receiving element. Such an acceleration device can be implemented, for example, by a friction roller acting on the outer edge of the receiving element or its base body. In this way, the forces required for acceleration can be transmitted as frictional forces. Alternatively, however, it is also possible to provide toothing between the receiving element or the base body and the acceleration device.

Um ein unbeabsichtigtes Lösen des Kantenbandes vom Wickelkern zu gewährleisten, wenn die Rolle bereits weitestgehend abgewickelt ist, ist nach einer vorteilhaften Ausführungsform der vorliegenden Erfindung vorgesehen, dass das am Wickelkern liegende Ende des Kantenbandes mit dem Wickelkern verbunden, insbesondere verklemmt oder verklebt, ist.In order to ensure an unintentional detachment of the edge band from the winding core when the roll has already been largely unwound, according to an advantageous embodiment of the present invention it is provided that the end of the edge band lying on the winding core is connected to the winding core, in particular clamped or glued.

Nach einer weiteren bevorzugten Ausführungsform der vorliegenden Erfindung weist die erfindungsgemäße Kantenbandkassette eine Austrittsstelle auf, an welcher das freie Ende des Kantenbandes aus der Kassette herausführbar ist. Um diese Austrittsstelle herum können weitere Einrichtungen vorgesehen sein. So kann zum Beispiel eine seitliche Führung vorhanden sein, sodass das Kantenband an der Austrittsstelle seitlich im Bereich seiner Schmalseiten geführt ist. Auf diese Weise wird sichergestellt, dass ein seitliches Verrutschen beim Herausziehen des Kantenbandes aus der Kantenbandkassette vermieden wird.According to a further preferred embodiment of the present invention, the edge band cassette according to the invention has an exit point at which the free end of the edge band can be guided out of the cassette. Further devices can be provided around this exit point. For example, a lateral guide can be present, so that the edge band is guided laterally at the exit point in the area of its narrow sides. In this way it is ensured that lateral slippage when the edge band is pulled out of the edge band cassette is avoided.

Weiter kann die erfindungsgemäße Kantenbandkassette eine Klemmvorrichtung zum Klemmen des freien Endes des Kantenbandes aufweisen. Auf diese Weise wird verhindert, dass das Kantenband versehentlich in die Kassette zurückrutscht, bevor es verarbeitet werden kann. Bevorzugt kann dabei vorgesehen sein, dass die Klemmwirkung gegenüber dem Kantenband wieder aufhebbar ist, sodass der weitere Betrieb, bzw. das Einziehen des Kantenbandes in eine Kantenbearbeitungsvorrichtung, nicht beeinträchtigt wird.Furthermore, the edging tape cassette according to the invention can have a clamping device for clamping the free end of the edging tape. This prevents the edgeband from accidentally slipping back into the cassette before it can be processed. It can preferably be provided that the clamping effect on the edge band can be canceled again, so that further operation or the drawing of the edge band into an edge processing device is not impaired.

Insbesondere kann vorgesehen sein, dass die Klemmvorrichtung, vorzugsweise auf der Innenseite des Kassettengehäuses, im Bereich des Austritts des Kantenbandes aus dem Kassettengehäuse, insbesondere benachbart zur oben genannten Austrittsstelle angeordnet ist.In particular, it can be provided that the clamping device is arranged, preferably on the inside of the cassette housing, in the region of the exit of the edge band from the cassette housing, in particular adjacent to the above-mentioned exit point.

An der erfindungsgemäßen Kantenbandkassette kann zudem eine Informationseinrichtung vorgesehen sein, die beispielsweise Informationen darüber enthält, welche Sorte Kantenband im Innern der Kassette enthalten ist; solche Informationen können zum Beispiel die Kantenhöhe, Kantenbreite, Kantenfarbe, vorhandene Laufmeter der Kante oder dergleichen beinhalten.An information device can also be provided on the edging tape cassette according to the invention, which device contains, for example, information about what type of edging tape is contained inside the cassette; such Information may include, for example, edge height, edge width, edge color, existing linear meters of the edge, or the like.

Die in den Figuren 1 und 2 gezeigte Kantenbandkassette weist ein Kassettengehäuse 18 auf, in welchem das erfindungsgemäße Aufnahmeelement 1 untergebracht ist. Am Aufnahmeelement ist ein Wickelkern 3 bevorzugt lösbar angebracht, welcher sich mit dem Aufnahmeelement 1 dreht. Auf dem Wickelkern 3 ist ein Kantenband 2 aufgewickelt. Das freie Ende 2a des Kantenbandes 2 kann an einer Austrittsstelle aus dem Kassettengehäuse 18 entnommen werden. Der Wickelkern 3 ist insbesondere drehfest mit dem Aufnahmeelement 1 verbunden. Die Drehung des Aufnahmeelements 1 bewirkt also eine Drehung des Wickelkerns 3 und damit je nach Drehrichtung ein Aufspulen oder Abspulen des Kantenbandes 2. Bei der erfindungsgemäßen Kantenbandkassette gibt es mehrere Möglichkeiten, wie ein Aufwickeln bzw. Abwickeln des Kantenbandes erfolgen kann. Dazu können an verschiedenen Stellen optionale Antriebe 19, 20, 22 vorgesehen sein. Üblicherweise wird die Kantenbandkassette in einen Schacht eines Kassettenvorrats eingeschoben. Eine 1. Möglichkeit des Antriebs wäre danach beispielsweise das Antriebsrad 19, welches beispielsweise über einen zuschaltbaren Antriebsriemen im Kassettenschacht (nicht gezeigt) angetrieben werden kann. Eine weitere Möglichkeit wäre beispielsweise an einem externen Werkzeug (zum Beispiel einen Roboter) eine Antriebsrolle 20, die an einer bestimmten Position 21 auf der Oberseite (oder einer anderen Schmalseite) der Kassette dem Aufnahmeelement 1 zugestellt wird. Über den Reibschluss zwischen der Antriebsrolle 20 und dem Aufnahmeelement 1 kann ein Drehen des Aufnahmeelements 1 und damit ein Drehen der Kantenbandrolle 2 bewirkt werden. Eine weitere Option besteht darin, beispielsweise über einen Rollenzug 22 unmittelbar an der Austrittsöffnung der Kantenbandkassette das Kantenbandende 2a zu erfassen und zu fördern. Alle diese Antriebe können optional vorgesehen sein, können aber auch in beliebiger Kombination vorhanden sein.The in the figures 1 and 2 Edge tape cassette shown has a cassette housing 18, in which the inventive Recording element 1 is accommodated. A winding core 3 , which rotates with the receiving element 1 , is preferably detachably attached to the receiving element. An edge band 2 is wound onto the winding core 3 . The free end 2a of the edge band 2 can be removed from the cassette housing 18 at an exit point. The winding core 3 is in particular connected to the receiving element 1 in a rotationally fixed manner. The rotation of the receiving element 1 thus causes the winding core 3 to rotate and thus, depending on the direction of rotation, the edging tape 2 is wound up or unwound. For this purpose, optional drives 19, 20, 22 can be provided at various points. The edgeband cassette is usually inserted into a slot in a supply of cassettes. A first possibility of the drive would then be, for example, the drive wheel 19, which can be driven, for example, via a switchable drive belt in the cassette compartment (not shown). A further possibility would be, for example, a drive roller 20 on an external tool (for example a robot), which is delivered to the receiving element 1 at a specific position 21 on the upper side (or another narrow side) of the cassette. The frictional connection between the drive roller 20 and the receiving element 1 can cause the receiving element 1 to rotate and thus the edging tape roller 2 to rotate. A further option consists in grasping and conveying the edge band end 2a directly at the outlet opening of the edge band cassette, for example by means of a roller train 22 . All of these drives can be provided optionally be, but can also be present in any combination.

Weiter kann eine Einrichtung 24 vorgesehen sein, welche in der Lage ist, die Kantenbandrolle 2 bzw. das Aufnahmeelement 1 entweder abzubremsen oder aber sogar komplett zu fixieren, sodass ein Drehen nicht mehr möglich ist. Letzteres kann zum Beispiel zu Transportzwecken dienen.Furthermore, a device 24 can be provided which is capable of either braking the edge band roll 2 or the receiving element 1 or even completely fixing it so that rotation is no longer possible. The latter can be used for transport purposes, for example.

Schließlich kann die Kantenbandkassette im Bereich der Austrittsöffnung eine Klemmeinrichtung 23 aufweisen, die dazu ausgebildet ist, dass herausgezogene Kantenbandende 2a im Bereich der Austrittsöffnung festzuklemmen, damit dieses nicht versehentlich in das Kantengehäuse 18 hineinrutscht. Dabei kann auch vorgesehen sein, dass die Klemmwirkung der Klemmeinrichtung 23 aufhebbar ist, sodass das Herausführen des Kantenbandes aus dem Kassettengehäuse 18 problemlos und ohne Behinderung möglich ist. Gleichzeitig kann diese Klemmeinrichtung auch als Kantenführung ausgebildet sein, insbesondere zu den Schmalseiten hin können Führungselemente vorhanden sein, die ein seitliches Abrutschen des Kantenbandes 2a verhindern.Finally, the edging tape cassette can have a clamping device 23 in the area of the exit opening, which is designed to clamp the pulled-out edging tape end 2a in the area of the exit opening so that it does not inadvertently slide into the edge housing 18 . Provision can also be made here for the clamping effect of the clamping device 23 to be able to be canceled so that the edge band can be guided out of the cassette housing 18 without any problems or hindrances. At the same time, this clamping device can also be designed as an edge guide; guide elements can be present in particular towards the narrow sides, which prevent the edge band 2a from slipping off to the side.

Das erfindungsgemäße Aufnahmeelement 1, welches nun anhand einer bevorzugten Ausführungsform anhand der Figuren 3 bis 6 erläutert werden soll, weist zum Fixieren des aufgewickelten Kantenbands 2 einen Wickelkern auf. Dieser Wickelkern kann bevorzugt eine Innenklemmeinrichtung 3 aufweisen, wie sie nachfolgend beschrieben wird. Die Erfindung funktioniert allerdings mit jeder Art von Wickelkern, eine nachfolgend beschriebene Innenklemmeinrichtung 3 ist daher lediglich als Option zu verstehen.The receiving element 1 according to the invention, which is now based on a preferred embodiment based on the Figures 3 to 6 is to be explained, has a winding core for fixing the wound edge band 2 . This winding core can preferably have an inner clamping device 3, as will be described below. However, the invention works with any type of winding core, an inner clamping device 3 described below is therefore only to be understood as an option.

Die Innenklemmeinrichtung 3 ist dazu ausgebildet, nach außen gerichtete Kräfte auf die nach innen gerichtete Fläche 17 des Gebindes des aufgewickelten Kantenbands 2 auszuüben.The inner clamping device 3 is designed to exert outwardly directed forces on the inwardly directed surface 17 of the bundle of the wound edge band 2 .

In vorteilhafter Weise weist das beispielhafte Aufnahmeelement 1 einen scheibenförmigen Grundkörper 4 auf. Der Grundkörper 4 ist in vorteilhafter Weise zumindest im Wesentlichen rotationssymmetrisch ausgebildet.The exemplary receiving element 1 advantageously has a disc-shaped base body 4 . The base body 4 is advantageously at least essentially rotationally symmetrical.

Die Innenklemmeinrichtung 3 weist in vorteilhafter Weise eine Mehrzahl - im gezeigten Beispiel drei - Spannelemente 5 auf. Diese sind zur Fixierung des aufgewickelten Kantenbands 2 gegen die nach innen gerichtete Fläche 17 des Gebindes des aufgewickelten Kantenbandes 2 verspannbar. In vorteilhafter Weise wirken die Spannelemente 5 so nach Art von Spannbacken.The inner clamping device 3 advantageously has a plurality—three in the example shown—on clamping elements 5 . These can be braced against the inwardly directed surface 17 of the container of the wound edge band 2 in order to fix the wound edge band 2 . The clamping elements 5 advantageously act in the manner of clamping jaws.

Die Spannelemente 5 sind an dem Grundkörper 4 zum Fixieren des Kantenbandes 2 jeweils entlang einer Spannrichtung X verschieblich geführt. In vorteilhafter Weise weist die Spannrichtung X im gezeigten Beispiel in radialer Richtung bezogen auf die scheibenförmige Erstreckung des Grundkörpers 4. Zur Ermöglichung der Führung der Spannelemente 5 entlang ihrer jeweiligen Spannrichtung X weist der Grundkörper 4 Führungselemente 6 auf. Die Führungselemente 6 sind in Fig. 4 zu erkennen. Sie greifen in komplementäre Nuten 7 in den Spannelementen 5, die in den Fig. 2 und 3 zu erkennen sind, ein und bewirken so die Führung der Bewegung der Spannelemente 5.The clamping elements 5 are each guided displaceably along a clamping direction X on the base body 4 for fixing the edging strip 2 . In the example shown, the clamping direction X advantageously points in the radial direction in relation to the disk-shaped extent of the base body 4 . To enable the clamping elements 5 to be guided along their respective clamping direction X, the base body 4 has guide elements 6 . The guide elements 6 are in 4 to recognize. They engage in complementary grooves 7 in the clamping elements 5 in the 2 and 3 can be seen, and thus bring about the guidance of the movement of the clamping elements 5.

Weiterhin weist das erfindungsgemäße Aufnahmeelement 1 in vorteilhafter Weise ein Drehelement 8 auf. Das Drehelement 8 ist in vorteilhafter Weise zentrisch am Grundkörper 4 angeordnet. Das Drehelement 8 ist zum Fixieren des Kantenbandes 2 drehbar. Die Drehbarkeit wird im gezeigten Beispiel in vorteilhafter Weise durch eine rotierbare Lagerung des Drehelements 8 am Grundkörper 4 bewirkt. Zu diesem Zweck weist das Drehelement eine mittige kreisförmige Ausnehmung 9 auf, in die ein am Grundkörper 4 aufgenommenes, ebenfalls in vorteilhafter Weise kreisförmiges, Führungselement 10 eingreift.Furthermore, the receiving element 1 according to the invention advantageously has a rotary element 8 . The rotating element 8 is advantageously arranged centrally on the base body 4 . The rotating element 8 can be rotated to fix the edge band 2 in place. In the example shown, the rotatability is brought about advantageously by rotatably mounting the rotary element 8 on the base body 4 . For this purpose, the rotary element has a circular recess 9 in the center, into which a guide element 10, which is accommodated on the base body 4 and is also advantageously circular, engages.

Bei einer Drehung des Drehelements 8 gleiten, vorzugsweise spiralförmig gestaltete, Anlageflächen 11 des Drehelements 8 an korrespondierenden Anlageflächen 12 der Spannelemente 5 ab. Die Spannelemente 5 werden hierdurch nach außen und gegen die nach innen gerichtete Fläche 17 des Gebindes des Kantenbandes 2 gedrückt. Die Funktionsweise geht aus dem Vergleich der Fig. 2 und 3 hervor. Ausgehend von Fig. 2 bewirkt eine Drehung des Drehelements 8 das Abgleiten der Anlageflächen 11 und 12 aneinander, so dass die Spannbacken 5 in radialer Richtung nach außen gedrückt werden, bis sie eine in Fig. 3 beispielhaft dargestellte Position erreichen, in der das Kantenband 2 fixiert ist.When the rotating element 8 rotates, contact surfaces 11 , preferably designed in a spiral shape, of the rotating element 8 slide off on corresponding contact surfaces 12 of the clamping elements 5 . As a result, the clamping elements 5 are pressed outwards and against the inwardly directed surface 17 of the container of the edge band 2 . The way it works is based on the comparison of the 2 and 3 out. Starting from 2 rotation of the rotary element 8 causes the contact surfaces 11 and 12 to slide against one another, so that the clamping jaws 5 are pressed outwards in the radial direction until they form an in 3 Reach the position shown as an example, in which the edge band 2 is fixed.

Um einen besseren Zusammenhang der Innenklemmeinrichtung 3 zu gewährleisten, weisen das Drehelement 8 und die Spannelemente 5 im Bereich ihrer Anlageflächen 11 und 12 ineinandergreifende Nuten 13 auf. Die ineinandergreifenden Nuten 13 sind bevorzugt ebenfalls spiralförmig gestaltet.In order to ensure a better connection of the inner clamping device 3 , the rotary element 8 and the clamping elements 5 have grooves 13 which engage in one another in the region of their contact surfaces 11 and 12 . The interlocking grooves 13 are preferably also designed in a spiral shape.

In ebenfalls vorteilhafter Weise weist der scheibenförmige Grundkörper 4 ein erstes Verbindungselement 14 zum Verbinden eines Werkzeugs zum Fixieren des Kantenbandes 2 mit dem Aufnahmeelement 1 auf. Dieses erste Verbindungselement 14 ist in vorteilhafter Weise so gestaltet, dass es zusätzlich als Lagerungselement zur rotierbaren Lagerung des Aufnahmeelements 1 dienen kann. Weiterhin weist in vorteilhafter Weise die Innenklemmeinrichtung 3 ein, im gezeigten Beispiel am Drehelement 8 angeordnetes, zweites Verbindungselement 15 zur Verbindung des Werkzeugs mit dem Aufnahmeelement 1 auf. Das Werkzeug kann so am ersten Verbindungselement 14 angesetzt werden und - das erste Verbindungselement 14 als Drehpunkt nutzend - über das zweite Verbindungselement 15 die Drehbewegung des Drehelements 8 bewirken.In a likewise advantageous manner, the disc-shaped base body 4 has a first connecting element 14 for connecting a tool for fixing the edge band 2 to the receiving element 1 . This first connecting element 14 is advantageously designed in such a way that it can also serve as a bearing element for the rotatable bearing of the receiving element 1 . Furthermore, the inner clamping device 3 advantageously has a second connecting element 15 , which is arranged on the rotating element 8 in the example shown, for connecting the tool to the receiving element 1 . The tool can thus be attached to the first connecting element 14 and—using the first connecting element 14 as a fulcrum—cause the rotary movement of the rotary element 8 via the second connecting element 15 .

Schließlich weist das beispielhafte erfindungsgemäße Aufnahmeelement 1 vorzugsweise ein Fixierelement 16 auf. Bei diesem kann es sich beispielsweise um eine Schraube handeln, welche das Drehelement 8 gegen den Grundkörper 4 drückt und so einen Reibschluss zur Verhinderung der Drehbewegung des Drehelements 8 relativ zum Grundkörper 4 erzeugt. Auf diese Weise kann eine sichere Fixierung der Innenklemmeinrichtung 3 sichergestellt werden. Im gezeigten Beispiel ist vorteilhafterweise durch die ineinandergreifenden Nuten 13 gleichzeitig eine formschlüssige Fixierung der Spannelemente 5 an dem Grundkörper 4 gegeben, wenn das Drehelement 8 durch das Fixierelement 16 am Grundkörper 4 fixiert wird.Finally, the exemplary receiving element 1 according to the invention preferably has a fixing element 16 . This can be a screw, for example, which presses the rotary element 8 against the base body 4 and thus creates a frictional connection to prevent the rotary movement of the rotary element 8 relative to the base body 4 . In this way, a secure fixation of the inner clamping device 3 can be ensured. In the example shown, the intermeshing grooves 13 advantageously simultaneously provide a form-fitting fixation of the clamping elements 5 on the base body 4 when the rotary element 8 is fixed on the base body 4 by the fixing element 16 .
