Description

Die Erfindung betrifft eine Verwendung einer Aufnahmevorrichtung nach dem Oberbegriff von Anspruch 1 Eine solche Verwendung ist aus dem Dokument DE102017125039 B3 bekannt.The invention relates to a use of a recording device according to the preamble of claim 1. Such a use is from the document DE102017125039 B3 known.

Möbelplatten aus Holz- oder Holzersatzstoffen weisen oftmals bereits vor ihrer Weiterverarbeitung wenigstens eine zumindest teilweise beschichtete Deckfläche auf. Die Beschichtungsarten reichen von Lackierungen bis hin zu Verkleidungen mit Lagen aus Echtholzfurnier oder Kunststoff. Neben verbesserter Optik und Pflege weisen oberflächenbeschichtete Möbelplatte zudem eine erhöhte Beständigkeit gegenüber mechanischen Einwirkungen und Flüssigkeiten auf. Da bereits beschichtete Möbelplatten oftmals einen Zuschnitt erfahren, erfolgt die Beschichtung ihrer schmalen Randseiten erst im Nachgang. Beim sogenannten Bekanten wird hierzu zumindest abschnittsweise ein Kantenband an der unbeschichteten Schmalseite der Möbelplatte angeordnet. Dessen Befestigung basiert in der Regel auf Adhäsion oder/ und einem Mikroformschluss durch lokales Anschmelzen.Furniture boards made of wood or wood substitutes often have at least one at least partially coated top surface before they are further processed. The types of coating range from paintwork to paneling with layers of real wood veneer or plastic. In addition to improved appearance and care, surface-coated furniture boards also have increased resistance to mechanical influences and liquids. Since furniture boards that have already been coated are often cut to size, their narrow edges are only coated afterwards. In so-called edging, an edging strip is arranged at least in sections on the uncoated narrow side of the furniture panel. Its attachment is usually based on adhesion and/or a micro form fit through local melting.

Im industriellen Rahmen erfolgt die Bekantung von Holzwerkstoffplatten durch eine Bekantungsanlage, in der die Kantenbänder mit wenigstens einer Bekantungsmaschine im Durchlaufverfahren verarbeitet werden. Die Kantenbänder liegen dabei in zumeist aufgerollter Form als Kantenrollen vor, um auch große Längen auf möglichst kompakte Weise sicher transportieren und lagern zu können. Für eine möglichst einfache Handhabung können diese auch innerhalb einer Kassette angeordnet und bei Bedarf aus dieser abspulbar sein. Aufgrund der Vielfalt an Farben und Dekoren sowie Dicken (Stärke) der zu bekantenden Möbelplatten müssen die Kantenbänder oftmals gewechselt und gegen die jeweils passende Variante ausgewechselt werden.In the industrial context, the edging of wood-based panels is carried out by an edging system in which the edge bands are processed with at least one edging machine in a continuous process. The edging tapes are usually available in a rolled-up form as edging rolls in order to be able to transport and store large lengths safely and in the most compact way possible. For the simplest possible handling, these can also be arranged within a cassette and can be unwound from this if necessary. Due to the variety of colors and decors as well as thicknesses (thickness) of the furniture panels to be edged, the edgebands often have to be changed and replaced with the appropriate variant.

Da zu Kantenrollen aufgewickelte Kantenbänder ein naturgemäßes Bestreben zum unkontrollierten Abwickeln und Versatz zwischen ihren einzelnen Windungen zeigen, bedarf der Umgang mit diesen einer entsprechenden Vorsicht. Dabei kommt deren kontrolliert abwickelbarer Lagerung eine erhöhte Bedeutung zu.Since edging strips wound into edging rolls show a natural tendency towards uncontrolled unwinding and misalignment between their individual windings, handling them requires appropriate caution. In this context, their controlled, developable storage is of increased importance.

So beschreiben DE 10 2017 125 039 B3 und DE 101 25 761 A1 Aufnahmevorrichtungen für eine Kantenbandrolle, welche jeweils einen um eine Drehachse herum rotierbar gelagerten Nabenkörper umfassen. In einer senkrecht zur Drehachse des Nabenkörpers verlaufenden Ebene erstreckt sich ein Scheibenelement, das der seitlichen Abstützung einer durch den Nabenkörper aufnehmbaren Kantenbandrolle dienen kann. Der jeweilige Nabenkörper weist wenigstens zwei Stützbacken auf, die zur zumindest indirekten Innenklemmung der wenigstens teilweise auf den Nabenkörper aufsetzbaren Kantenbandrolle ausgebildet sind.How to describe DE 10 2017 125 039 B3 and DE 101 25 761 A1 Receiving devices for a roll of edge banding, which each comprise a hub body that is mounted such that it can rotate about an axis of rotation. A disk element extends in a plane running perpendicularly to the axis of rotation of the hub body and can serve to laterally support an edge band roll that can be accommodated by the hub body. The respective hub body has at least two supporting jaws, which are designed for at least indirect internal clamping of the edging tape roll that can be placed at least partially on the hub body.

Die Innenklemmung ermöglicht eine präzise und sichere Lagerung der Kantenbandrolle, die ohne weitergehende Niederhalter oder sonstige Sicherungseinrichtungen auskommt. Die beweglichen Stützbacken erzeugen dabei eine in Ebene der Kantenbandrolle wirkende radiale Verspannung der einzelnen aufeinander gewickelten Lagen des Kantenbandes untereinander, was deren sonst möglichen Versatz wirksam hemmt.The internal clamping enables precise and safe storage of the edgeband roll, which does not require any further hold-down devices or other safety devices. The moveable supporting jaws produce a radial bracing of the individual layers of the edge band that are wound on top of one another, which acts in the plane of the edge band roll, which effectively inhibits their otherwise possible misalignment.

Aus dem Stand der Technik bekannte Innenklemmungen erfordern genügend Bauraum, um deren bewegliche Teile betätigen zu können. Dies ist insbesondere dann relevant, wenn mehrere solcher Aufnahmevorrichtungen, beispielsweise im Zusammenhang mit jeweils einer Kassette, nebeneinander anzuordnen sind. Derartige Anordnungen sind regelmäßig bei der industriellen Bekantung von Holzwerkstoffplatten anzutreffen, wo eine Vielzahl solcher Aufnahmevorrichtungen beispielsweise in Regalen, Schränken oder Wagen zusammengefasst werden.Known from the prior art inner clamps require enough space to actuate their moving parts. This is particularly relevant when a number of such recording devices are to be arranged next to one another, for example in connection with one cassette each. Such arrangements are regularly found in the industrial edging of wood-based panels, where a variety of such recording devices are combined, for example, in shelves, cabinets or trolleys.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine wie zuvor beschriebene Aufnahmevorrichtung dahingehend weiterzuentwickeln, dass diese eine möglichst klein bauende Ausgestaltung ihrer Innenklemmung für eine Kantenbandrolle aufweist.The present invention is based on the object of further developing a receiving device as described above in such a way that it has the smallest possible configuration of its internal clamping for a roll of edge banding.

Diese Aufgabe wird durch eine Aufnahmevorrichtung mit den Merkmalen von Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.This object is achieved by a recording device having the features of claim 1. Advantageous configurations are the subject matter of the dependent claims.

Erfindungsgemäß weist die Aufnahmevorrichtung eine Verriegelungsmechanik auf, welche ein relativ zum, insbesondere auf einer Welle gelagerten, Nabenkörper um die Drehachse herum begrenzt rotierbares Stellelement besitzt. Weiterhin ist wenigstens ein das Stellelement mit einer der Stützbacken koppelnder Arm vorgesehen. Die Anordnung und Ausgestaltung von Stellelement und Arm sowie deren Zusammenwirken ist derart gewählt, dass die rotatorische Beweglichkeit des Stellelements in eine radial zur Drehachse erfolgende lineare Verlagerung der mit dem Arm gekoppelten Stützbacke übersetzbar ist.According to the invention, the receiving device has a locking mechanism which has an actuating element which can be rotated to a limited extent about the axis of rotation relative to the hub body, which is in particular mounted on a shaft. Furthermore, at least one arm coupling the actuating element to one of the supporting jaws is provided. The arrangement and design of the actuating element and arm and their interaction is selected in such a way that the rotational mobility of the actuating element can be translated into a linear displacement of the supporting jaw coupled to the arm, taking place radially with respect to the axis of rotation.

Der sich hieraus ergebende Vorteil ist darin zu sehen, dass die zur Innenklemmung notwendige Kinematik vollständig parallel zum Scheibenelement erfolgt. Mit anderen Worten sind keine in oder parallel zur Drehachse erfolgende Verlagerungen von Teilen der Aufnahmevorrichtung nötig, so dass die Innenklemmung eine überaus schlanke Ausgestaltung aufweist. Durch die über den Arm erfolgende Übersetzung der rotatorischen Beweglichkeit des Stellelements in eine translatorische Verlagerung der mit dem Arm gekoppelten Stützbacke ergibt sich eine präzise arbeitende Innenklemmung. Die Übersetzung kann eine ausreichend große Selbsthemmung aufweisen, um die erforderliche Spannung zu halten. Ein etwaiges "Durchrutschen" zwischen drehbarem Nabenkörper und einer auf diesen aufgesetzten Kantenbandrolle ist so wirksam verhindert. Durch die rein lineare Verlagerbarkeit der wenigstens einen mit dem Arm gekoppelten Stützbacke ergeben sich keinerlei Relativbewegungen zur Kantenbandrolle.The resulting advantage can be seen in the fact that the kinematics required for the internal clamping take place completely parallel to the disk element. In other words, there is no need for parts of the receiving device to be displaced in or parallel to the axis of rotation, so that the inner clamp has an extremely slim design. By taking place over the arm translation of the rotational mobility of the actuator in a Translational displacement of the supporting jaw coupled with the arm results in a precisely working inner clamping. The translation can have a sufficiently high level of self-locking to maintain the required voltage. This effectively prevents any "slipping" between the rotating hub body and an edging tape roll placed on it. Due to the purely linear displaceability of the at least one supporting jaw coupled to the arm, there are no movements relative to the edging tape roll.

Nach einer besonders bevorzugten Weiterbildung des grundsätzlichen Erfindungsgedankens kann die wenigstens eine linear verlagerbare Stützbacke durch mindestens eine Linearführung an dem Nabenkörper gelagert sein. Hierdurch ergibt sich eine stabile sowie präzise Führung der Stützbacke, insbesondere in radialer Richtung.According to a particularly preferred development of the basic idea of the invention, the at least one linearly displaceable support jaw can be mounted on the hub body by at least one linear guide. This results in stable and precise guidance of the support jaw, particularly in the radial direction.

In vorteilhafter Weise kann die wenigstens eine linear verlagerbare Stützbacke federbelastet sein. Die Federbelastung der Stützbacke kann derart erfolgen, dass diese zur Drehachse des Nabenkörpers hin zumindest teilweise gegen die Federbelastung verlagerbar ist. Demgegenüber kann die Verlagerung der Stützbacke von der Drehachse weg zumindest teilweise durch die Federbelastung unterstützt sein. Auf diese Weise ist sichergestellt, dass stets eine ausreichende Spannung für die Innenklemmung zur Verfügung steht, die beispielsweise nur zum Austausch der Kantenbandrolle entgegen der Federbelastung reduzierbar bis vollständig aufhebbar ist. Auch bei einem möglichen Defekt in der Kopplung zwischen dem Arm und dem Stellelement oder/und der Stützbacke ist somit weiterhin gewährleistet, dass die Kantenbandrolle im Sinne einer Notlaufeigenschaft sicher auf dem Nabenkörper gehalten ist.The at least one linearly displaceable support jaw can advantageously be spring-loaded. The spring loading of the supporting jaw can take place in such a way that it can be displaced towards the axis of rotation of the hub body at least partially against the spring loading. In contrast, the displacement of the supporting jaw away from the axis of rotation can be at least partially assisted by the spring loading. In this way, it is ensured that there is always sufficient tension for the internal clamping available, which can be reduced or completely canceled against the spring load, for example, only to replace the roll of edge banding. Even in the event of a possible defect in the coupling between the arm and the actuating element and/or the support jaw, it is thus still ensured that the edgeband roll is held securely on the hub body in the sense of an emergency running property.

Bevorzugt kann die wenigstens eine linear verlagerbare Stützbacke über ein Federelement an dem Nabenkörper abgestützt sein. Die sich aus einer Federbelastung einer Stützbacke ergebenden Vorteile wurden bereits zuvor näher erläutert. Die Anordnung eines Federelements zwischen Stützbacke und Nabenkörper kann dabei zusätzlich zu der zuvor beschriebenen Federbelastung erfolgen oder eine Umsetzung selbiger darstellen. In jedem Fall bewirkt die Anordnung des Federelements zwischen Nabenkörper und Stützbacke eine direkte Beaufschlagung letzterer mit einer Federkraft, ohne wartungsintensive oder/und zusätzlichen Bauraum benötigende Umlenkungen.The at least one linearly displaceable support jaw can preferably be supported on the hub body via a spring element. The advantages resulting from spring loading of a supporting jaw have already been explained in more detail above. The arrangement of a spring element between the support jaw and the hub body can take place in addition to the spring loading described above or represent an implementation of the same. In any case, the arrangement of the spring element between the hub body and the supporting jaw causes a direct loading of the latter with a spring force, without deflections requiring intensive maintenance and/or additional installation space.

Weiter können der Nabenkörper und das Scheibenelement verdrehfest miteinander verbunden sein. Hierdurch kann das Scheibenelement quasi als leicht greifbares Gegenlager dienen, um die Innenklemmung der Aufnahmevorrichtung über eine drehende Relativbewegung zum Stellelement entsprechend zu manipulieren.Furthermore, the hub body and the disk element can be connected to one another in a torsion-proof manner. As a result, the disc element can serve as an easily grippable abutment in order to correspondingly manipulate the internal clamping of the receiving device via a rotating movement relative to the actuating element.

Es ist vorgesehen, dass das Stellelement auf einem Abschnitt des Nabenkörpers drehbar gelagert sein kann. Grundsätzlich kann das Stellelement zumindest teilweise als Ring ausgebildet sein. Insbesondere in Kombination mit der zuvor erwähnten möglichen verdrehfesten Verbindung zwischen Scheibenelement und Nabenkörper ist so die drehbare Lagerung des Stellelements auf kleinem Raum gegeben.It is provided that the adjusting element can be rotatably mounted on a section of the hub body. In principle, the actuating element can be designed at least partially as a ring. In particular in combination with the previously mentioned possible non-rotatable connection between the disk element and the hub body, the rotatable mounting of the actuating element is thus provided in a small space.

Gemäß einer besonders vorteilhaften Ausgestaltung der erfindungsgemäßen Aufnahmevorrichtung kann die jeweilige Stützbacke wenigstens zwei Teile aufweisen. Konkret kann jede der Stützbacken eine Grundbacke und eine Erweiterungsbacke umfassen. Die Erweiterungsbacke ist in geeigneter Weise mit der zugehörigen Grundbacke koppelbar, bevorzugt magnetisch. Durch die zumindest Zweiteilung jeder Stützbacke ergibt sich ein überaus flexibler Einsatz für Kantenbandrollen mit unterschiedlichen Innendurchmessern. So ist durch Weglassen oder Anordnen der Erweiterungsbacken an den Grundbacken der Außenradius des Nabenkörpers an einen Innenradius der auf diesen aufzusetzenden Kantenbandrolle in einfacher Weise anpassbar.According to a particularly advantageous embodiment of the receiving device according to the invention, the respective supporting jaw can have at least two parts. Specifically, each of the support jaws may include a base jaw and an extension jaw. The extension jaw can be coupled in a suitable manner to the associated base jaw, which is preferred magnetic. The fact that each supporting jaw is at least divided into two results in an extremely flexible use for edgeband rolls with different inner diameters. Thus, by omitting or arranging the extension jaws on the base jaws, the outer radius of the hub body can be easily adapted to an inner radius of the edging tape roll to be placed on it.

Bevorzugt kann der Nabenkörper wenigstens drei Stützbacken besitzen, wobei die Verriegelungsmechanik eine an die Menge der Stützbacken angepasste Anzahl an Armen besitzt. Die Arme erstrecken sich dabei parallel zum Scheibenelement und sind jeweils mit einer der Stützbacken und dem Stellelement gekoppelt. Durch die wenigstens drei Stützbacken ergibt sich eine präzise Führung der Kantenbandrolle, deren Innenumfang zu maximal einem Drittel mit einer der Stützbacken korrespondiert.The hub body can preferably have at least three supporting jaws, with the locking mechanism having a number of arms adapted to the number of supporting jaws. The arms extend parallel to the disk element and are each coupled to one of the support jaws and the actuating element. The at least three supporting jaws result in precise guidance of the edge band roll, the inner circumference of which corresponds to a maximum of one third with one of the supporting jaws.

Auch kann das Stellelement der erfindungsgemäßen Aufnahmevorrichtung mechanisch gegenüber seiner Rotierbarkeit um die Drehachse herum festlegbar sein. Auf diese Weise ist sichergestellt, dass die Innenklemmung keine unbeabsichtigte Lösung selbiger erfährt. Die temporäre Festlegung des Stellelements kann bevorzugt durch eine geeignete Blockiereinrichtung erfolgen.The actuating element of the receiving device according to the invention can also be fixed mechanically with respect to its ability to rotate about the axis of rotation. In this way it is ensured that the inner clamping does not experience any unintentional loosening of the same. The setting element can be temporarily fixed by a suitable blocking device.

Die erfindungsgemäße Aufnahmevorrichtung ermöglicht einen schlanken Aufbau, insbesondere in Bezug auf seine Verriegelungsmechanik.The receiving device according to the invention enables a slim design, in particular with regard to its locking mechanism.

Fig. 1 zeigt eine erfindungsgemäße Aufnahmevorrichtung 1 in einer ersten schematischen Ansicht. Die Aufnahmevorrichtung 1 umfasst ein Scheibenelement 2, welches aus Übersichtsgründen nicht in seiner vollen radialen Ausdehnung dargestellt ist (fehlende Teile sind durch schwarze Strich-Punkt-Linien abgetrennt). Im Zentrum des Scheibenelements 2 befindet sich ein (hier beispielhaft als Dreieck gestalteter) Ausschnitt 2a, durch welchen hindurch sich zumindest abschnittsweise eine Welle 3 erstreckt. Auf der Welle 3 ist um deren Drehachse X herum ein Nabenkörper 4 drehbar gelagert. Das sich in einer senkrecht zur Drehachse X verlaufenden Ebene erstreckende Scheibenelement 2 ist hier rein beispielhaft über insgesamt drei Befestigungsmittel 5a 5c verdrehfest mit dem Nabenkörper 4 verbunden. Auf diese Weise sind Scheibenelement 2 und Nabenkörper 4 gemeinsam um die Drehachse X der Welle 3 herum rotierbar. 1 shows a recording device 1 according to the invention in a first schematic view. The receiving device 1 comprises a disk element 2, which is not shown in its full radial extent for reasons of clarity (missing parts are separated by black dash-dot lines). In the center of the disk element 2 there is a cutout 2a (designed here by way of example as a triangle) through which a shaft 3 extends at least in sections. A hub body 4 is rotatably mounted on the shaft 3 about its axis of rotation X. The disk element 2 extending in a plane running perpendicularly to the axis of rotation X is here, purely by way of example, connected to the hub body 4 in a rotationally fixed manner by a total of three fastening means 5a 5c. In this way, the disk element 2 and the hub body 4 can be rotated together about the axis of rotation X of the shaft 3 .

Um die Welle 3 herum sind in der hier rein beispielhaft gezeigten Ausführungsform insgesamt drei Stützbacken 6a-6c angeordnet, welche jeweils über eine Linearführung 7a-7c an dem Nabenkörper 4 linear beweglich gelagert sind. Weiterhin ist jede dieser Stützbacken 6a-6c zusätzlich über ein zugehöriges Federelement 8a-8c an dem Nabenkörper 4 abgestützt. Die Federelemente 8a-8c erzeugen eine permanente Federbelastung der linear verlagerbaren Stützbacken 6a-6c, so dass diese zur Drehachse X der Welle 3 hin gegen die Federbelastung und von der Drehachse X weg zumindest teilweise durch die Federbelastung verlagerbar sind.In the embodiment shown here purely as an example, a total of three supporting jaws 6a-6c are arranged around the shaft 3, which are each mounted so as to be linearly movable on the hub body 4 via a linear guide 7a-7c. Furthermore, each of these supporting jaws 6a-6c is additionally over an associated spring element 8a-8c is supported on the hub body 4. The spring elements 8a-8c produce a permanent spring load on the linearly displaceable support jaws 6a-6c, so that they can be displaced towards the axis of rotation X of the shaft 3 against the spring load and away from the axis of rotation X at least partially by the spring load.

Wie zu erkennen, weisen die Stützbacken 6a-6c in der hier rein beispielhaft gezeigten Ausführungsform eine Zweiteilung auf, so dass jede Stützbacke 6a-6c eine Grundbacke 9a-9c und eine mit der zugehörigen Grundbacke 9a-9c gekoppelte Erweiterungsbacke 10a-10c umfasst. Durch entsprechendes Weglassen oder Anordnen der Erweiterungsbacken 10a-10c ist der der Außenradius des Nabenkörpers 4 an den Innenradius einer hier nicht näher gezeigten, auf den Nabenkörper 4 aufsetzbaren Kantenbandrolle entsprechend anpassbar.As can be seen, the supporting jaws 6a-6c in the embodiment shown here purely as an example are divided into two, so that each supporting jaw 6a-6c comprises a base jaw 9a-9c and an extension jaw 10a-10c coupled to the associated base jaw 9a-9c. By appropriately omitting or arranging the expansion jaws 10a-10c, the outer radius of the hub body 4 can be correspondingly adapted to the inner radius of an edge band roll that can be placed on the hub body 4 and is not shown in detail here.

Fig. 2 zeigt die Aufnahmevorrichtung 1 aus Fig. 1 in einer um 180° gedrehten schematischen Ansicht. In dieser Darstellung fällt der Blick auf die Rückseite des Scheibenelements 2 und durch deren Ausschnitt 2a hindurch. Hierdurch ist eine Verriegelungsmechanik 11 der Aufnahmevorrichtung 1 erkennbar, die - zur Etablierung einer Innenklemmung für eine Kantenbandrolle - der bedarfsweisen Verlagerung der linear beweglichen Stützbacken 6a-6c dient. Hierzu besitzt die Verriegelungsmechanik 11 ein auf einem Abschnitt des Nabenkörpers 4 drehbar gelagertes Stellelement 12, welches in der hier gezeigten Ausführungsform rein beispielhaft die Form eines Rings aufweist. Das Stellelement 12 ist über insgesamt drei Arme 13a-13c mit jeweils einer der drei Stützbacken 6a-6c gekoppelt. Durch seine Lagerung an dem Nabenkörper 4 ist das Stellelement 12 relativ zu diesem um die Drehachse X herum begrenzt rotierbar. 2 shows the recording device 1 1 in a schematic view rotated by 180°. In this representation, the view falls on the rear side of the pane element 2 and through its cutout 2a. This shows a locking mechanism 11 of the receiving device 1, which serves to shift the linearly movable support jaws 6a-6c as required—to establish an internal clamping for a roll of edging tape. For this purpose, the locking mechanism 11 has an actuating element 12 which is rotatably mounted on a section of the hub body 4 and which, in the embodiment shown here, has the shape of a ring, purely by way of example. The actuating element 12 is coupled via a total of three arms 13a-13c to one of the three supporting jaws 6a-6c. Due to its storage on the hub body 4, the actuating element 12 relatively rotatable around the axis of rotation X around limited.

In dem hier gezeigten verriegelten Zustand Z1 erstrecken sich die Arme 13a-13c parallel zu den Federelementen 8a-8c, so dass diese in Fig. 1 entsprechend verdeckt und insofern nicht ersichtlich sind.In the locked state Z1 shown here, the arms 13a-13c extend parallel to the spring elements 8a-8c, so that these 1 are correspondingly covered and therefore not visible.

Fig. 3 ist ein entriegelter Zustand Z2 der Verriegelungsmechanik 11 zu entnehmen. Erkennbar ist das Stellelement 12 hierzu gegen den Uhrzeigersinn rotiert worden. In der Folge wurde die rotatorische Bewegung des Stellelements 12 in eine radial zur Drehachse X erfolgende lineare Verlagerung der mit dem Arm 13a-13c gekoppelten Stützbacke 6a-6c übersetzt, so dass diese quasi - in nicht näher gezeigter Weise - aus ihrer ursprünglichen Ringebene um die Welle 3 beziehungsweise den Nabenkörper 4 herum leicht zurückgezogen wurden. Der entriegelte Zustand Z2 ermöglicht das Aufsetzen einer Kantenbandrolle auf und das Entfernen einer Kantenbandrolle von dem Nabenkörper 4. 3 an unlocked state Z2 of the locking mechanism 11 can be seen. The adjusting element 12 has been rotated counterclockwise for this purpose. As a result, the rotational movement of the actuating element 12 was translated into a linear displacement of the supporting jaw 6a-6c coupled to the arm 13a-13c, radially to the axis of rotation X, so that this quasi - in a manner not shown in detail - from its original ring plane around the Shaft 3 or the hub body 4 were slightly withdrawn. The unlocked state Z2 allows a roll of edge banding to be placed on and a roll of edge banding to be removed from the hub body 4.

In nicht näher ersichtlicher Weise kann die Aufnahmevorrichtung 1 auch beispielweise eine Bremsvorrichtung besitzen, durch welche das um die Drehachse X herum rotierbare Stellelement 12 festlegbar sein kann.In a way that is not clear, the receiving device 1 can also have a braking device, for example, by means of which the actuating element 12, which can be rotated about the axis of rotation X, can be fixed.

Fig. 4 zeigt einen Schnitt durch die Aufnahmevorrichtung 1 in Ebene der Drehachse X. Hierin wird nochmals der in dem Scheibenelement 2 angeordnete Ausschnitt 2a und die sich durch diesen erstreckende Welle 3 verdeutlicht. Weiterhin erkennbar ist, dass der Nabenkörper 4 über Kugellager 14 drehbar an der Welle 3 gelagert ist. Zudem ist eine Stabachse 15b von insgesamt drei Stabachsen 15a-15c erkennbar, über welche die Arme 13a-13c jeweils endseitig mit einer der Stützbacken 6a-6c - insbesondere deren jeweiligen Grundbacke 9a-9c - schwenkbar gekoppelt sind (siehe auch Fig. 1 bis Fig. 3). 4 shows a section through the receiving device 1 in the plane of the axis of rotation X. This again shows the cutout 2a arranged in the disc element 2 and the shaft 3 extending through it. It can also be seen that the hub body 4 is rotatably mounted on the shaft 3 via ball bearings 14 . In addition, a rod axis 15b of a total of three rod axes 15a-15c can be seen, via which the arms 13a-13c each end with a of the support jaws 6a-6c - in particular their respective base jaw 9a-9c - are pivotally coupled (see also Figures 1 to 3 ).
