Description

Die vorliegende Erfindung bezieht sich auf eine Wickelwalze nach dem Oberbegriff des Anspruchs 1, bzw des Anspruchs 2.The present invention relates to a winding roller according to the preamble of claim 1 or claim 2.

Aus der WO 96/32874 A ist ein Verfahren zum vereinfachten Einfädeln und/oder Bewegen von flächigem Bandmaterial in einem Handtuchspender bekannt. Zum Aufwickeln des Handtuchs dient in einer Variante ein Wickeldorn, der in einen End-Bund - einen offenen Saum - des Handtuchs eingeschoben wird. Im Falle von automatisierten Einfädelvorgängen sind spezielle Endstücke an den sauberen Handtuchrollen vorgesehen, die in Nuten oder Wickelfedern einer Walze eingreifen und das Handtuch nach dessen Benutzung aufrollen.WO 96/32874 A describes a simplified method Threading and / or moving flat strip material into known a towel dispenser. For winding up the towel In one variant, a winding mandrel is used, which is in an end collar - an open hem - the towel inserted becomes. In the case of automated threading processes special end pieces are provided on the clean towel rolls, which engage in grooves or coil springs on a roller and roll up the towel after using it.

Diese Lösungen sind voll funktionsfähig, sie erfordern aber eine spezielle Aufbereitung bzw. Ausrüstung des Bandmaterials, was bei den in grossen Stückzahlen installierten Geräten den Unterhalt und die notwendige Logistik massiv verteuert. Es hat sich insbesondere gezeigt, dass die bestehenden Waschmaschinen, Mangen und Trocknungsanlagen für textile Handtuchrollen, in ihren ordentlichen und bereits optimierten Betriebsabläufen gestört werden, wenn eine Handtuchrolle mit veränderter endseitiger Ausgestaltung vorkommt.These solutions are fully functional, but they require special preparation or equipment of the strip material, what with the devices installed in large numbers maintenance and the necessary logistics are massively more expensive. It has been shown in particular that the existing Washing machines, mangles and drying systems for textile towel rolls, in their neat and already optimized operations are disrupted when a Towel roll with modified end design occurs.

Es ist daher Aufgabe der Erfindung eine Wickelwalze für bandförmiges, zum Händetrocknen geeignetes Bandmaterial zu schaffen, welche am Bandmaterial selbst keine Massnahmen oder Veränderungen erfordert, ein einfaches und rasches Handhaben erlaubt, den Wickelvorgang ohne Nachrutschen des Bandmaterials gewährleistet und sauber gewickelte Rollen, auch bei nassem und verschmutztem Material ergibt.It is therefore an object of the invention to provide a winding roller for band-shaped band material suitable for drying hands create which no measures on the strip material itself or changes, simple and quick Handle allows the wrapping process without slipping Band material guaranteed and neatly wound rolls, results even with wet and dirty material.

Die Einrichtung soll ohne zusätzliche Hilfsmittel oder Fremdenergien manuell bequem einsetzbar sein.The facility should be without additional aids or External energies can be conveniently used manually.

Diese Aufgabe wird durch die Merkmale der nebengeordneten Ansprüche 1 und 2 erfüllt.This task is characterized by the characteristics of the sibling Claims 1 and 2 met.

Die Ausführungsform nach Anspruch 1 zeichnet sich durch ihre einfache Herstellung aus.The embodiment according to claim 1 is characterized by their simple manufacture.

Die Ausführung nach Anspruch 2 ist in der Fabrikation aufwendiger und aufgrund ihrer feingliedrigen Klemmschiene empfindlicher auf eine rauhe Behandlung beim Auswechseln der Handtuchrolle.The embodiment according to claim 2 is more complex to manufacture and because of their slender clamping rail more sensitive to rough treatment when changing the towel roll.

Beide Varianten erlauben ein sehr einfaches Beladen eines Handtuchspenders mit einem sauberen Handtuch und ein ebenso leichtes Entfernen der Wickelwalze am benutzten Handtuch, d.h. die Wickelwalze verbleibt beim Handtuchspender, wenn die schmutzige Handtuchrolle in die Wäscherei zurückgeschickt wird; sie wird mit der nächsten sauberen Rolle verwendet.Both variants allow very easy loading of one Towel dispensers with a clean towel and one as well easy removal of the winding roller from the used towel, i.e. the winding roller remains with the towel dispenser if the dirty towel roll sent back to the laundry becomes; it is used with the next clean roll.

Dies führt zu einer vereinfachten Logistik und spart Material und Transportgewicht. - In der Wäscherei lassen sich mit den "offenen" Enden der Handtuchrollen die maschinenbedingte, maximale Anzahl Waschzyklen pro Stunde erreichen.This leads to simplified logistics and saves material and transport weight. - Can be in the laundry with the "open" ends of the towel rolls the machine-related reach the maximum number of washing cycles per hour.

Bei anderen als textilen Bandmaterialien ergeben sich ähnliche Vorteile, selbst dann, wenn das Material nur rezirkuliert wird. For tape materials other than textile, there are similar ones Advantages, even if the material only recirculates becomes.

In weiteren, abhängigen Ansprüchen sind vorteilhafte Weiterbildungen der Ansprüche 1 und 2 beschrieben.Advantageous further developments are in further, dependent claims of claims 1 and 2 described.

Die Ausgestaltung nach Anspruch 3 ergibt eine hohe Friktion zwischen dem Bandmaterial und der Wickelwalze, was einen schlupffreien Betrieb garantiert.The embodiment according to claim 3 results in high friction between the strip material and the winding roller, which one Slip-free operation guaranteed.

Die Ausführungsform nach Anspruch 4 sichert ein definiertes Fixieren des Bandmaterials, ohne dass beim Schliessen des Schwenkhebels Überlappungen und Falten entstehen. Durch die resultierende linienförmige Klemmung des Bandmaterial lässt sich der gesamte Wickelkörper in axialer Richtung, auch aus einer straff gewickelten Rolle entfernen.The embodiment according to claim 4 ensures a defined Fix the tape material without having to close the Swivel lever overlaps and folds occur. Through the resulting linear clamping of the band material leaves the entire winding body in the axial direction, too remove a tightly wound roll.

Zusätzlich erleichtert ein Langloch an der Schwenkstelle die achsparallele Positionierung des Schwenkhebels.In addition, an elongated hole at the swivel point makes it easier the axially parallel positioning of the swivel lever.

Besonders vorteilhaft ist die einstückige Ausgestaltung der Klemmschiene in Kombination mit dem seitlichen Flansch, Anspruch 5, wodurch diese auch in einem Kunststoffmaterial realisiert, eine ausreichende Festigkeit erhält.The one-piece design of the Clamping rail in combination with the side flange, claim 5, which also makes this in a plastic material realized, receives sufficient strength.

Die linienförmigen Auflager nach Anspruch 6 ergeben eine optimale Klemmwirkung in radialer Richtung, ohne das Herausziehen der Wickelwalze in axialer Richtung zu behindern.The linear supports according to claim 6 result in a optimal clamping effect in the radial direction without pulling out to hinder the winding roller in the axial direction.

Die Ausbildung der Oberseite der Klemmschiene gemäss Anspruch 7 gewährleistet über den ganzen Umfang der Wickelwalze einen gleichmässigen Reibungswiderstand.The formation of the top of the clamping rail according to claim 7 ensures over the entire circumference of the winding roller an even frictional resistance.

Von besonderer Bedeutung ist der Querschnitt der Klemmschiene, damit diese leicht in das Bandmaterial einführund auch ausziehbar ist, vgl. Anspruch 8. The cross-section of the clamping rail is of particular importance, so that it can be easily inserted into the tape material is also extendable, cf. Claim 8.

Durch eine progressive Zunahme des Querschnitts in Richtung Einspannstelle der Feder können diese Vorgänge zusätzlich erleichtert werden.By progressively increasing the cross-section towards The spring can clamp these processes additionally be relieved.

Seitliche Lagerzapfen nach Anspruch 9 bewirken eine gute Führung der Rolle im Handtuchspender und erlauben eine vereinfachte Handhabung beim Austausch des Bandmaterials.Lateral trunnions according to claim 9 cause a good Guide the roll in the towel dispenser and allow a simplified Handling when changing the tape material.

Besonders bewährt hat sich eine Ausführung nach Anspruch 10, aus Kunststoff, da diesem die Nässe und weitere dem schmutzigen Handtuch anhaftende Stoffe nichts anhaben können.An execution according to claim has proven particularly successful 10, made of plastic, because this is the wet and the other Dirty towels adhering to fabrics cannot harm them.

Anhand von Zeichnungen werden nachfolgend praktische Ausführungsbeispiele der Erfindung näher beschrieben.Practical exemplary embodiments are described below with the aid of drawings described the invention in more detail.
