Description

Die Erfindung betrifft ein Spendesystem mit einem Spender und mit mindestens einer Nachfüllung. Die Nachfüllung weist eine zu einer Rolle, vorzugsweise kernlos gewickelte Materialbahn und zwei Lagerzapfen auf, von denen jeder einen Endteil eines beidseitig aus der Rolle vorstehenden Tragstabs bildet, wobei zumindest einer der beiden Lagerzapfen mit mindestens einer nicht als Rotationsfläche ausgebildeten Passfläche versehen ist. Der Spender weist eine in einer Spendeposition endende Führung für den Tragstab auf, an deren Beginn für jeden mit einer Passfläche versehenen Lagerzapfen eine Gegenfläche zur Passfläche vorgesehen ist, sodass das Einsetzen der Rolle in den Spender nur bei Koinzidenz der Passfläche und ihrer Gegenfläche in der Einführungsposition möglich ist.The invention relates to a dispensing system with a dispenser and at least one refill. The refill has a web, preferably coreless wound material web and two bearing pins, each of which forms an end portion of both sides of the roller projecting support rod, wherein at least one of the two bearing pins is provided with at least one not designed as a surface of rotation mating surface. The dispenser has a dispensing position terminating guide for the support rod, at the beginning of each provided with a mating bearing pin a counter surface is provided to the mating surface, so that the insertion of the roller in the dispenser only coincidence of the mating surface and its counter surface in the insertion position is possible.

Unter einer nicht als Rotationsfläche ausgebildeten Fläche wird dabei eine Fläche verstanden, deren Erzeugende im Abstand zur Achse des Lagerzapfens variiert. Nicht als Rotationsfläche ausgebildete Flächen sind vor allem ebene, gegebenenfalls auch gekrümmte, Seitenflächen von Stegen oder Nuten, die stirnseitig an den Lagerzapfen vorgesehen sind, Stufenflächen am Lagerzapfenende bzw. eine prismatische Mantelfläche am Endabschnitt des Lagerzapfens.A surface which is not formed as a surface of revolution is understood to mean a surface whose generatrix varies at a distance from the axis of the bearing journal. Not designed as a surface of revolution surfaces are mainly flat, possibly also curved, side surfaces of webs or grooves which are provided on the front side of the bearing pin, step surfaces on the bearing journal end or a prismatic lateral surface at the end portion of the journal.

Die Rollen umfassen unterschiedliche Materialbahnen, die auf Kernen bzw. auch kernlos gewickelt und anschließend mit den durchgehenden Tragstäben bestückt werden, um die Materialbahn in einem Spender abrollen zu können. Dies trifft vor allem dann zu, wenn die Rollen von einem Rollenstrang geschnitten werden, wie dies im Allgemeinen bei Haushaltspapier, Sanitärpapier, Toilettenpapier usw. der Fall ist. Aufnahmen oder Führungen für derartige Rollen in Spendern weisen im allgemeinen Nuten auf, in die die Lagerzapfen eingeführt werden. Da auf die richtige Anordnung der Rollen geachtet werden muss, damit das Ende der Materialbahn immer an derselben Seite von der Rolle herabhängt, werden die Lagerzapfen und die zugehörigen Führungen an den beiden Seiten unterschiedlich ausgebildet.The rollers comprise different material webs, which are wound on cores or coreless and then fitted with the continuous support rods to roll the web in a dispenser can. This is especially true when the rolls are cut from a roll strand, as is generally the case with household paper, sanitary paper, toilet paper, etc. Receivers or guides for such roles in dispensers generally have grooves into which the trunnions are inserted. Since care must be taken to ensure the correct arrangement of the rollers, so that the end of the material web always depends on the same side of the roller, the bearing pins and the associated guides are formed differently on the two sides.

Insbesondere bei Materialbahnen mit geringem Wert, wie beispielsweise bei Haushaltspapier, Toilettenpapier oder anderen Sanitärpapieren, sind auch die für die Lagerzapfen verwendeten Materialien eher preisgünstig und weisen daher nur eine hinreichende Stabilität oder Festigkeit auf, die die Anwendung ermöglicht. Die Lagerzapfen sind daher nicht gegen Beschädigungen sicher, die durch gewaltsame Versuche verursacht werden können, die Rolle trotz der eindeutigen Zuordnung durch die unterschiedliche Ausgestaltung der beiden Seiten falsch in den Spender einzulegen.Especially with material webs of low value, such as household paper, toilet paper or other sanitary papers, the materials used for the journals are rather inexpensive and therefore have only one sufficient stability or strength that allows the application. The journals are therefore not safe against damage that may be caused by violent attempts to insert the role despite the clear assignment by the different design of the two sides wrong in the dispenser.

Ein derartiger Tragstab sowie ein Spender, in den Rollen mit dem beidseitig vorstehenden Tragstab eingesetzt werden, sind aus der EP 1 927 308 bekannt. Ein Lagerzapfen des Tragstabs weist dort einen vom Mittelbereich des Tragstabs durch eine Umfangsnut distanzierten Endflansch auf, der an seiner Stirnseite mit einer Nut versehen ist, deren Seitenwände jeweils eine nicht als Rotationsfläche ausgebildete Passfläche darstellen. Der Endflansch des Lagerzapfens lässt sich in eine hinterschnittene Führung in der Seitenwand des Spenders einschieben, an deren Anfang ein stegartiger Vorsprung vorgesehen ist, der der stirnseitigen Nut im Lagerzapfen entspricht, und dessen Seitenflächen somit Gegenflächen zu den Passflächen der Nut bilden. Beim Einsetzen muss daher die Rolle bzw. der Lagerzapfen so verdreht werden, dass die Koinzidenz der beiden Flächen erreicht ist. Erst dann kann die Rolle in den Spender eingeschoben werden. Da der Tragstab im Mittelbereich abstehende Stege aufweist, auf denen die gewickelte Materialbahn verdrehfest gehalten ist, sodass sich der Tragstab beim Abziehen der Materialbahn mit der Rolle mitdreht, endet der stegartige Vorsprung weit vor der Spendeposition der Rolle, und die Lagerzapfen können sich in der Spendeposition der Rolle beliebig drehen.Such a support rod and a dispenser, are used in the roles with the double-sided projecting support rod, are from the EP 1 927 308 known. A bearing journal of the support rod there has a distal from the central region of the support rod by a circumferential groove end flange, which is provided on its front side with a groove whose side walls each represent a not designed as a surface of rotation mating surface. The end flange of the bearing pin can be inserted into an undercut guide in the side wall of the dispenser, at the beginning of a web-like projection is provided which corresponds to the frontal groove in the journal, and its side surfaces thus form mating surfaces to the mating surfaces of the groove. When inserting, therefore, the roller or the journal must be rotated so that the coincidence of the two surfaces is reached. Only then can the roll be inserted into the dispenser. Since the support rod in the central region has projecting webs on which the wound material web is held rotationally so that the support rod rotates when removing the material web with the roller, the web-like projection ends well before the dispensing position of the roller, and the journals can in the dispensing position turn the roll as you like.

Die Erfindung hat es sich nun zur Aufgabe gestellt, bei einem Spendesystem der eingangs genannten Art Vereinfachungen sowohl am Spender als auch an den Tragstäben zu schaffen, ohne dass die gegebenen Vorteile des aus der EP 1 927 308 bekannten Spendesystems verringert sind.The invention has now taken on the task of creating a dispensing system of the type mentioned simplifications both on the donor and on the support rods, without the benefits of the given from EP 1 927 308 known dispensing system are reduced.

Erfindungsgemäß wird dies dadurch erreicht, dass sich die Gegenfläche des Spenders an der Führung von der Einführungsposition bis in die Spendeposition erstreckt, und dass die Rolle drehbar auf dem Mittelbereich des in der Spendeposition unverdrehbaren Tragstabes angeordnet ist, wobei die Wicklung der Materialbahn den Mittelbereich des Tragstabes so umschließt, dass ein Losbrechdrehmoment von höchstens 0,2 Nm, vorzugsweise 0,1 Nm zum Abziehen der Materialbahn eingebracht werden muss.According to the invention this is achieved in that the counter surface of the dispenser on the guide extends from the insertion position to the dispensing position, and that the roller is rotatably arranged on the central region of the non-rotatable support rod in the dispensing position, wherein the winding of the material web the central region of the support rod so enclosing that a breakaway torque of at most 0.2 Nm, preferably 0.1 Nm must be introduced to strip the web.

Bevorzugt beträgt ein Folgedrehmoment für die weitere Abwicklung der Materialbahn zwischen 0,0025 und 0,1 Nm, vorzugsweise 0,05 Nm, sodass sie sich in gewohnter Weise unter geringer Bremswirkung abziehen lässt.Preferably, a follow-up torque for the further development of the material web is between 0.0025 and 0.1 Nm, preferably 0.05 Nm, so that it can be removed in the usual way with little braking effect.

In einer besonders vereinfachten Ausführung ist vorgesehen, dass der Lagerzapfen eine Nut in der Stirnseite aufweist, und die Führung am Spender in ihrer gesamten Länge durch eine vorstehende Rippe gebildet ist, auf die die Nut aufschiebbar ist. Bevorzugt können die Rippe und die Nut schwalbenschwanzförmig ausgebildet sein.In a particularly simplified embodiment, it is provided that the bearing journal has a groove in the end face, and the guide is formed on the dispenser in its entire length by a protruding rib, on which the groove is pushed. Preferably, the rib and the groove may be dovetail-shaped.

Zur Verwendung in dem erfindungsgemäßen Spendesystem ist insbesondere ein Tragstab vorgesehen, bei dem der mit der Passfläche versehene Lagerzapfen und der Mittelbereich denselben Durchmesser aufweisen.For use in the dispensing system according to the invention, in particular a support rod is provided, in which the bearing journal provided with the mating surface and the central region have the same diameter.

Wenn der Durchmesser des zweiten Lagerzapfens kleiner als der Durchmesser des zwischen den beiden Lagerzapfen vorgesehenen Mittelbereichs des Tragstabs ist, erleichtert dies vor allem die Bestückung kernlos gewickelter und von einem Strang abgelängter Materialbahnen, da der verringerte Durchmesser des zweiten Lagerzapfens, der insbesondere gerundet endet, in die meist sehr kleine mittige Öffnung der kernlosen Wicklung eingeschoben werden kann.If the diameter of the second journal is smaller than the diameter of the provided between the two journals central portion of the support rod, this facilitates mainly the placement of coreless wound and cut from a strand material webs, since the reduced diameter of the second journal, which ends in particular rounded in the usually very small central opening of the coreless winding can be inserted.

Zu Rollen 3 gewickelte Materialbahnen 12, insbesondere von Haushalts- oder Sanitärpapier benötigen im Allgemeinen, da sie von einem Strang geschnitten werden, stirnseitig vorstehende Lagerzapfen 4, 5, wenn sie nach dem Öffnen eines Deckels 25 in Führungen 21, 24 eines Spenders 20 (Fig. 1) eingesetzt und dort in einer Spendeposition 10 drehbar gelagert werden. Die Lagerzapfen 4, 5 sind dabei an den Enden eines Tragstabs 1 vorgesehen, wobei in den Figuren 2, 3 und 7 links ein einfacher zylindrischer Lagerzapfen 4 gezeichnet ist, der in eine Nut einer Führung 24 des Spenders 20 passt. Prinzipiell ist es aber auch möglich, den Lagerzapfen 4 und dessen Führung 24 ebenfalls in der nachstehend für den rechts gezeigten Lagerzapfen 5 und dessen Führung 21 beschriebenen Möglichkeit auszubilden, wie Fig. 7 zeigt.Rolls 3 wound material webs 12, in particular of household or sanitary paper generally require, since they are cut by a strand, frontally projecting trunnions 4, 5, when after opening a lid 25 in guides 21, 24 of a dispenser 20 (FIGS. Fig. 1 ) are used and rotatably supported there in a dispensing position 10. The bearing pins 4, 5 are provided at the ends of a support rod 1, wherein in the Figures 2 . 3 and 7 On the left a simple cylindrical bearing journal 4 is drawn, which fits into a groove of a guide 24 of the dispenser 20. In principle, it is also possible to form the bearing journal 4 and its guide 24 also in the manner described below for the bearing pin 5 shown on the right and its guide 21, as Fig. 7 shows.

Um die Rollen 3 nur lagerichtig in die unterschiedlichen Führungen 21, 24 des Spenders 20 einsetzen zu können, sodass die Materialbahn 12 immer an derselben Seite von der Rolle 3 abgezogen wird (Fig. 1), ist die Führung 21 als von der Wand des Spenders 20 vorstehende Rippe 22 ausgebildet, die von der Einführposition 15 in die Spendeposition 10 durchgängig ist, und auf die der entsprechend ausgebildete Bereich des Lagerzapfens 5 in der Einführposition 15 aufgeschoben werden kann. Der Lagerzapfen 5 weist daher eine Nut 8 an der freien Stirnseite auf, die gegengleich zur Rippe 22 an der Wand des Spenders 20 ausgebildet ist. Die Seitenwände der Nut 8 sind Passflächen 9, die im Gegensatz zur Umfangsfläche des Lagerzapfens 5 keine Rotationsflächen darstellen, sondern insbesondere eben sind, und zu denen Gegenflächen 23 an der Rippe 22 vorgesehen sind. Da sich die Rippe 22 nicht nur in der Einführposition 15 am Anfang der Führung 21, sondern über deren gesamte Länge bis in die Spendeposition 10 erstreckt, folgt der Tragstab 1 der Krümmung der Rippe 22, wenn er, wie aus Fig. 3 ersichtlich ist, aus der Einführposition 15 (rechts in Fig. 3) in die Spendeposition 10 (links in Fig. 3) verschoben wird. In der Spendeposition 10 verdreht sich die Rolle 3 auf dem Mittelbereich 2 des Tragstabs 1, wenn die Materialbahn 12 in Richtung des Pfeiles 11 abgezogen wird. Der Tragstab 1 besteht vorzugsweise aus einem preiswerten Kunststoff, und weist im Mittelbereich 2 Aussparungen 6 auf, um spritzgießfähige Dimensionen ohne nennenswerte Materialanhäufungen zu erzielen.In order to use the rollers 3 only in the correct position in the different guides 21, 24 of the dispenser 20, so that the material web 12 is always deducted on the same side of the roller 3 ( Fig. 1 ), the guide 21 is formed as projecting from the wall of the dispenser 20 rib 22 which is continuous from the insertion position 15 in the dispensing position 10, and on which the correspondingly formed portion of the journal 5 can be pushed in the insertion position 15. The bearing pin 5 therefore has a groove 8 on the free end face, which is formed opposite to the rib 22 on the wall of the dispenser 20. The side walls of the groove 8 are mating surfaces 9, which in contrast to the peripheral surface of the bearing journal 5 do not represent surfaces of revolution, but are in particular planar, and to which mating surfaces 23 are provided on the rib 22. Since the rib 22 extends not only in the insertion position 15 at the beginning of the guide 21, but over its entire length to the dispensing position 10, the support rod 1 follows the curvature of the rib 22 when he, as from Fig. 3 can be seen from the insertion position 15 (right in Fig. 3 ) in the dispensing position 10 (left in Fig. 3 ) is moved. In the dispensing position 10, the roller 3 rotates on the central region 2 of the support rod 1 when the material web 12 is withdrawn in the direction of the arrow 11. The support rod 1 is preferably made of a low-cost plastic, and has in the central region 2 recesses 6 in order to achieve injection-moldable dimensions without appreciable material accumulations.

Zwischen der innersten Wicklung der Materialbahn 12 und dem Tragstab 1 ist eine Gleitreibung gegeben, durch die eine vorteilhafte Bremswirkung beim Abziehen der Materialbahn 12 erreicht und in der Folge Materialverschwendung vermieden wird. Die Bremswirkung darf aber nicht so hoch sein, dass die Materialbahn 12 falsch abreißt bzw. nicht abgezogen werden kann. Günstige Verhältnisse liegen vor, wenn das Losbrechdrehmoment (Haftreibung), also jene Kraft, mit der am Ende der von der Rolle 3 hängenden Materialbahn 12 gezogen werden muss, 0,1 Nm, höchstens 0,2 Nm, beträgt, und wenn das nach Überwindung des Losbrechdrehmomentes zur Überwindung der Gleitreibung notwendige Folgedrehmoment 0,0025 Nm nicht unterschreitet.Between the innermost winding of the material web 12 and the support rod 1, a sliding friction is given by which achieves an advantageous braking effect when removing the material web 12 and as a result material waste is avoided. The However, the braking effect must not be so high that the material web 12 tears off incorrectly or can not be pulled off. Favorable conditions exist when the breakaway torque (static friction), ie the force with which the material web 12 hanging from the roll 3 has to be pulled, is 0.1 Nm, at most 0.2 Nm, and if that is after overcoming of the breakaway torque to overcome the sliding friction necessary follower torque 0.0025 Nm does not fall below.

Die Fig. 4 bis 6 zeigen unterschiedliche Querschnittsformen für die Nut 8 im Tragstab 1 und die Rippe 22 am Spender 20. Während Fig. 3 und Fig. 7 einen rechteckigen oder quadratischen Querschnitt zeigen, ist der Querschnitt in Fig. 4 dreieckig, in Fig. 5 schwalbenschwanzförmig und in Fig. 6 trapezförmig ausgebildet. Eine schwalbenschwanzförmige Ausbildung nach Fig. 5 hat den zusätzlichen Vorteil, dass der Tragstab 1 auch in seiner Längsrichtung an der Rippe 22 gehalten ist. In Fig. 6 ist auch eine Umfangsnut 7 im Lagerzapfen 5 gezeigt, sodass ein derartiger Tragstab auch noch in einen Spender nach der eingangs erwähnten EP 1 927 308 eingesetzt werden kann.The 4 to 6 show different cross-sectional shapes for the groove 8 in the support rod 1 and the rib 22 on the dispenser 20. During Fig. 3 and Fig. 7 show a rectangular or square cross section, the cross section is in Fig. 4 triangular, in Fig. 5 dovetailed and in Fig. 6 trapezoidal shaped. A dovetailed formation after Fig. 5 has the additional advantage that the support rod 1 is also held in its longitudinal direction on the rib 22. In Fig. 6 is also a circumferential groove 7 shown in the bearing pin 5, so that such a support rod even in a dispenser according to the above-mentioned EP 1 927 308 can be used.

Fig. 7 zeigt eine Variante, in der beide Führungen 21, 24 des Spenders und beide Lagerzapfen 4, 5 gleichartig ausgebildet sind. Unterschiedlich sind nur die Breite der Rippen 22 der beiden Führungen 21, 24 sowie die Breite der Nuten 8 in den Stirnseiten der beiden Lagerzapfen 4, 5, um die Rolle 3 nur lagerichtig einzusetzen. Der Lagerzapfen 4 verringert sich konisch im Durchmesser, um das Einsetzen des Tragstabes 1 in eine kernlos gewickelte Rolle 3 zu ermöglichen bzw. zu erleichtern. Auch dieser Tragstab kann Materialaussparungen 6 im Mittelbereich 2 aufweisen. Fig. 7 shows a variant in which both guides 21, 24 of the dispenser and both bearing pins 4, 5 are of similar design. Different are only the width of the ribs 22 of the two guides 21, 24 and the width of the grooves 8 in the end faces of the two journals 4, 5, to use the roller 3 only in the correct position. The journal 4 reduces conically in diameter to allow the insertion of the support rod 1 in a coreless wound roll 3 or to facilitate. This support rod may have material recesses 6 in the central region 2.
