Abstract

The bearing journal (5) has a rotating bearing surface (8) that is formed at the bottom of a circumferential groove (7), and a non-rotating fitting surface (9) that is formed on a recess (12) formed at the free end (11) of the journal. An axial guide surface (10) is formed by the side-surface of the circumferential groove proximal to the free end of the bearing journal. An independent claim is also included for a material dispensing system.

Description

Die Erfindung betrifft ein Spendesystem mit einem Spender für abzutrennende Abschnitte einer zu einer Rolle gewickelten Materialbahn und mit mindestens einer zu einer Rolle gewickelten Materialbahn, an deren beiden Stirnseiten je ein in Bezug auf die Rolle drehfest angeordneter Lagerzapfen vorsteht, wobei zumindest ein Lagerzapfen einen Endabschnitt aufweist, an dessen Umfang eine als Rotationsfläche ausgebildete Lagerfläche und in dessen freier Stirnseite eine Ausnehmung mit einer nicht als Rotationsfläche ausgebildeten Passfläche vorgesehen sind, wobei der Spender für den zumindest einen Lagerzapfen eine in einer Spendeposition endende Führung aufweist, in der der Endabschnitt des Lagerzapfens drehbar gelagert ist, und an deren Beginn eine Engstelle mit einer Gegenfläche zur Passfläche des Lagerzapfens vorgesehen ist, und wobei das Einsetzen der Rolle in den Spender nur bei Koinzidenz der Passfläche und ihrer Gegenfläche möglich ist. Weiters betrifft die Erfindung auch eine zu einer Rolle gewickelte Materialbahn zur Verwendung in diesem Spendesystem.The invention relates to a dispensing system with a dispenser for separated sections of a wound into a roll of material web and at least one wound to a roll of material web, at its two end faces each projecting with respect to the roller rotatably mounted bearing pin, wherein at least one journal has an end portion on whose circumference a bearing surface configured as a surface of revolution and in the free end face of which a recess with a mating face not formed as a surface of revolution are provided, wherein the dispenser for the at least one bearing journal has a guide ending in a dispensing position in which the end portion of the bearing journal is rotatably mounted is, and at the beginning of a constriction is provided with a mating surface to the mating surface of the journal, and wherein the insertion of the role in the dispenser is possible only when coincidence of the mating surface and its counter surface. Furthermore, the invention also relates to a web wound into a roll for use in this dispensing system.

Unter einer nicht als Rotationsfläche ausgebildeten Fläche wird dabei eine Fläche verstanden, deren Erzeugende im Abstand zur Achse des Lagerzapfens und der Rolle variiert. Nicht als Rotationsfläche ausgebildete Flächen sind somit, gegebenenfalls auch gekrümmte, Seitenflächen von Stegen oder Nuten, die stirnseitig an den Lagerzapfen vorgesehen sind, Stufenflächen in einer Abstufung des Lagerzapfenendes, 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 journal and the roller. Not designed as a surface of revolution surfaces are thus, possibly also curved, side surfaces of webs or grooves, which are provided on the front side of the bearing pin, step surfaces in a gradation of the journal end, or a prismatic lateral surface at the end portion of the journal.

Derartige Rollen umfassen unterschiedliche Materialbahnen, die auf Kernen oder Kernhülsen ( EP 657 134 ) bzw. auch kernlos ( WO 99/26521 ) gewickelt sind, wobei stirnseitig Lagerzapfen angebracht werden, um die Materialbahn 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. Für die Anbringung der Lagerzapfen bieten sich mehrere Möglichkeiten. Zum einen sind in die Rolle zwei Endstücke ( WO 99/26521 ) oder Endkappen ( US 5 249 755 , WO 99123719 ) einsetzbar, von denen die Lagerzapfen abstehen. Zum anderen können die Rollen mit durchgehenden Tragstäben ( US 4 340 195 ) bestückt werden, wobei die Tragstäbe länger als die Rollen sind und die überstehenden Endabschnitte die Lagerzapfen bilden. Aufnahmen oder Führungen für derartige Rollen an Haltern oder Spendern weisen im allgemeinen Nuten auf, in die die Lagerzapfen eingesetzt werden. Nach der WO 99/26521 sind die kernlos gewickelten Rollen mit stirnseitigen Vertiefungen versehen, in die die Lagerzapfen eingreifen. Dabei dreht sich die Rolle auf dem Lagerzapfen, und diese sind verdrehfest in den Führungen des Spenders angeordnet. Die Lagerzapfen weisen eine Umfangsnut auf, die von Stegen an den Führungen hintergriffen wird. Eine gleichartige axiale Führung ist auch im Spender nach der US 4 340 195 gegeben. Meist muss auf die richtige Anordnung der Rollen geachtet werden, damit das Ende der Materialbahn immer an derselben Seite von der Rolle herabhängt. Zu diesem Zweck ist es bekannt ( US 3 602 450 , US 4 340 195 ), die Lagerzapfen und die zugehörigen Führungen an den beiden Seiten mit unterschiedlichen Durchmessern und entsprechend unterschiedlichen Abständen der Führungsflächen der Führungen auszubilden. Die WO 96/23719 weist eine Umfangsnut im kleineren der beiden Lagerzapfen auf. Die Umfangsnut dient dort dazu, mehr als ein Kriterium an zumindest einer Seite vorzusehen, um das falsche Einlegen zu erschweren. So können beispielsweise auch zwei voneinander getrennte Rotationsflächen am Lagerzapfen vorgesehen sein, die mit zwei Stegen oder Rippen an den Führungsflächen korrespondieren. Als zusätzlicher Vorteil wird dabei auch angeführt, dass Lagerzapfen mit zwei Umfangsnuten auch in Führungen mit einer Rippe an den Führungsflächen eingelegt werden können, sodass ein Halter oder Spender nicht nur eine bestimmte Rolle aufnehmen kann. Dieser Vorteil bildet aber auch gleichzeitig einen Nachteil, da die so genannte Verschlüsselung, also eine konkrete Festlegung von Passflächen und Führungsflächen umgehbar ist, wenn an einem der beiden zusammen wirkenden Teile ein Kriterium nicht erfüllt werden muss, und die Lagerzapfen dennoch gewaltfrei in die Führungen passen.Such rolls comprise different material webs which are supported on cores or core sleeves ( EP 657 134 ) or coreless ( WO 99/26521 ) are wound, with the end face bearing journals are mounted in order to roll the web 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. For the attachment of the journals offer several possibilities. On the one hand are in the role of two end pieces ( WO 99/26521 ) or end caps ( US 5,249,755 . WO 99/12919 ) can be used, from which protrude the journals. On the other hand, the rollers with continuous support bars ( US 4 340 195 ), wherein the support rods are longer than the rollers and the protruding end portions form the journals. Receivers or guides for such roles on holders or dispensers generally have grooves into which the journals are inserted. After WO 99/26521 the coreless wound rolls are provided with frontal depressions, in which engage the journals. In this case, the roller rotates on the journal, and these are rotationally fixed in the guides of the dispenser arranged. The journals have a circumferential groove, which is engaged behind by webs on the guides. A similar axial guidance is also in the dispenser after the US 4 340 195 given. In most cases care must be taken to ensure the correct arrangement of the rollers, so that the end of the material web always hangs from the roller on the same side. For this purpose it is known ( US Pat. No. 3,602,450 . US 4 340 195 ), the bearing pins and the associated guides on the two sides with different diameters and correspondingly different distances of the guide surfaces of the guides form. The WO 96/23719 has a circumferential groove in the smaller of the two journals. There, the circumferential groove serves to provide more than one criterion on at least one side to make it difficult to insert incorrectly. Thus, for example, two separate rotation surfaces may be provided on the bearing journal, which correspond to two webs or ribs on the guide surfaces. As an additional advantage is also stated that bearing journal with two circumferential grooves can be inserted into guides with a rib on the guide surfaces, so that a holder or dispenser can not only take a specific role. This advantage also forms a disadvantage at the same time, since the so-called encryption, ie a concrete determination of mating surfaces and guide surfaces is bypassed when a criterion must not be met on one of the two co-acting parts, and still fit the journals non-violent in the guides ,

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 bevorzugt eine wiederholte Anwendung ermöglicht. Die Lagerzapfen sind aber 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 Halter oder Spender einzulegen.In particular, with material webs of low value, such as in household paper, toilet paper or other sanitary papers, the materials used for the journals are rather inexpensive and therefore have only a sufficient stability or strength, which preferably allows repeated use. However, the journals are 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 holder or dispenser.

Um das fehlerhafte Einlegen der Rollen auch mit leichter Gewaltanwendung auszuschließen, ist es aus der ein Spendesystem gemäß Oberbegriff des Patentanspruchs 1 zeigenden EP 657134 bekannt geworden, die Zuordnungssicherheit zwischen Lagerzapfen und Führungen dadurch zu erhöhen, dass im Einführabschnitt des Spenders in zumindest einer Führung eine Engstelle durch ein vorstehendes Leitelement und am zugehörigen Lagerzapfen eine entsprechende Ausnehmung ausgebildet sind. Beispielsweise kann der Lagerzapfen stirnseitig mit einer diametralen Nut versehen sein, sodass er einen korrespondierenden Steg in der Führung passieren kann. Der zweite Lagerzapfen ist zylindrisch und greift lose in einen Führungsschlitz an der anderen Gehäuseseite ein.In order to rule out the erroneous insertion of the roles even with a slight use of force, it is from a dispensing system according to the preamble of claim 1 pointing EP 657134 become known to increase the reliability of assignment between journals and guides in that in the insertion of the donor in at least one guide a bottleneck formed by a projecting guide element and the associated bearing pin a corresponding recess. For example, the journal be provided with a diametrical groove on the front side so that it can pass a corresponding web in the guide. The second bearing pin is cylindrical and engages loosely in a guide slot on the other side of the housing.

Da die Rollen in den Führungen sich leicht bewegen lassen müssen, beispielsweise um durch Schwerkraft von einer Vorratsposition in eine untere Spendeposition zu fallen, muss ein Verklemmen der Lagerzapfen in den Führungen möglichst vermieden werden. Dies lässt sich naturgemäß am leichtesten durch ausreichendes Spiel zwischen den zusammenwirkenden Teilen erzielen, wobei aber das Spiel natürlich nicht so groß werden darf, dass die Rollen erst wieder auch verkehrt, bzw. dass auch falsche Rollen eingelegt werden können.Since the rollers in the guides must be easy to move, for example, to fall by gravity from a storage position to a lower dispensing position, jamming of the journals in the guides must be avoided as possible. Of course, this is most easily achieved by sufficient play between the interacting parts, but of course the game must not be so great that the roles only wrong again, or that even wrong roles can be inserted.

Da ein übermäßiges Spiel vor allem in axialer Richtung zu diesen Schwierigkeiten führen kann, ist bei einem Spendesystem der eingangs genannten Art vorgesehen, dass der Lagerzapfen eine Umfangsnut aufweist, deren zur freien Stirnseite des Lagerzapfens nähere Seitenfläche als Axialführungsfläche des Lagerzapfens dient, und dass die Führung des Spenders mit in die Umfangsnut ragenden Stegen versehen ist, an denen eine Führungsfläche für die Axialführungsfläche des Lagerzapfens vorgesehen ist.Since excessive play, especially in the axial direction can lead to these difficulties, it is provided in a dispensing system of the type mentioned above, that the bearing journal has a circumferential groove whose closer to the free end of the journal pin side surface serves as an axial guide surface of the journal, and that the guide of the dispenser is provided with webs projecting into the circumferential groove, on which a guide surface is provided for the axial guide surface of the bearing journal.

Anders ausgedrückt, an die Umfangsnut schließt ein flanschartiger Abschnitt größeren Durchmessers an, der eine an zueinander gerichteten Stegen ausgebildete Führungsfläche an der Führung des Halters oder Spenders hintergreifen kann. Der Boden der Umfangsnut ist dabei insbesondere eine kreiszylindrische Fläche, kann aber auch eine Kegelfläche oder dergleichen sein.In other words, the circumferential groove is adjoined by a flange-like section of larger diameter, which can engage behind a guide surface formed on mutually facing webs on the guide of the holder or dispenser. The bottom of the circumferential groove is in particular a circular cylindrical surface, but may also be a conical surface or the like.

Da für die Ausgestaltung der Engstelle in der Führung des Spenders mehrere Möglichkeiten gegeben sind, ist bevorzugt vorgesehen, dass die Gegenfläche und die Führungsfläche des Spenders an einem in den ersten Abschnitt der Führung eingesetzten Einsatzstück vorgesehen sind. Die Spender können daher in einfacher Weise an unterschiedliche Lagerzapfen angepasst werden.Since there are several possibilities for the design of the constriction in the guide of the dispenser, it is preferably provided that the counter surface and the guide surface of the dispenser are provided on an insert piece inserted into the first section of the guide. The dispensers can therefore be easily adapted to different journals.

Nachstehend wird nun die Erfindung an Hand der beiliegenden Zeichnung näher beschrieben, ohne darauf beschränkt zu sein.

Zu Rollen gewickelte Materialbahnen, insbesondere von Haushalts- oder Sanitärpapier benötigen im Allgemeinen, da sie von einem Strang geschnitten werden, stirnseitig vorstehende Lagerzapfen 4, 5, die in Führungen eines Spenders eingesetzt und dort drehbar gelagert werden. Die Lagerzapfen 4, 5 können dabei an den Enden eines Tragstabes 1 oder an Endkappen 2, 3 vorgesehen sein, die beispielsweise in eine Kartonhülse 15 eingesetzt werden. In den Figuren 1 bis 3 ist jeweils links ein einfacher Lagerzapfen 4 mit einer kreiszylindrischen Rotationsfläche gezeichnet, der in eine Nut der Führung 20 passt. Prinzipiell ist es aber auch möglich die Lagerzapfen 4 und die Führungen 20 ebenfalls in einer der nachstehend für die jeweils rechts gezeigten Lagerzapfen 5 und Führungen 21 beschriebenen Möglichkeiten auszubilden.Rolled material webs, in particular of household or sanitary paper generally require, since they are cut by a strand, frontally projecting bearing pins 4, 5, which are used in guides of a dispenser and rotatably mounted there. The bearing pins 4, 5 can be provided at the ends of a support rod 1 or end caps 2, 3, which are used for example in a cardboard sleeve 15. In the FIGS. 1 to 3 in each case on the left a simple bearing journal 4 is drawn with a circular cylindrical surface of revolution, which fits into a groove of the guide 20. In principle, however, it is also possible to form the bearing journals 4 and the guides 20 likewise in one of the possibilities described below for the bearing journals 5 and guides 21 shown on the right in each case.

Jeder Lagerzapfen 5 weist ebenfalls eine kreiszylindrische Rotationsfläche als Lagerfläche 8 auf, die gemäß Fig. 1 bis 3 durch die Bodenfläche einer Umfangsnut 7 gebildet ist.Each journal 5 also has a circular-cylindrical surface of revolution as a bearing surface 8, according to Fig. 1 to 3 is formed by the bottom surface of a circumferential groove 7.

Um die Rollen nur lagerichtig in die unterschiedlichen Führungen 20, 21 des Spenders einsetzen zu können, sind an den Führungen 21 Engstellen 22 vorgesehen, die nur von entsprechend ausgebildeten Bereichen der Lagerzapfen 5 passiert werden können. Die Engstellen 22 werden durch in die Führung 21 ragende Vorsprünge 25 oder dergleichen gebildet, an denen erste Führungsflächen vorgesehen sind, die Gegenflächen 23 bilden, vorzugsweise parallel zur Achse der Rolle ausgebildet und mit ansteigenden Anfangsabschnitten 26 versehen sind. Bevorzugt sind die Engstellen 22 an Einsatzstücken 28 (Fig. 5, 6) vorgesehen, die in den Anfangsbereich der Führungen 21 eingefügt werden können.In order to use the rollers only in the correct position in the different guides 20, 21 of the dispenser, constrictions 22 are provided on the guides 21, which can only be passed by appropriately trained areas of the bearing pin 5. The bottlenecks 22 are formed by projecting into the guide 21 projections 25 or the like, on which first guide surfaces are provided, the mating surfaces 23 form, preferably formed parallel to the axis of the roller and provided with rising starting portions 26. Preferably, the bottlenecks 22 are on insert pieces 28 ( Fig. 5, 6 ), which can be inserted into the initial region of the guides 21.

Die Lagerzapfen 5 weisen Ausnehmungen 12 an den freien Stirnseiten 11 auf, die gegengleich zu den Vorsprüngen 25 in den Führungen 21 gebildet sind. Die Ausnehmungen 12 sind mit Passflächen 9 versehen, die im Gegensatz zu den Lagerflächen 8 keine Rotationsflächen darstellen, sondern insbesondere ebene Seitenflächen von stirnseitigen Nuten (Fig. 1, 2, 3, 4, 5-rechts). Wie die Figuren erkennen lassen, ermöglichen die nicht als Rotationsflächen ausgebildeten Passflächen 9 und die Gegenflächen 23 an den Vorsprüngen 25 eine große Anzahl von unterschiedlichen Kombinationen, falls eine Verschlüsselung zwischen den Lagerzapfen 5 und den Führungen 21 des Spenders gewünscht wird, um die Rollen nicht nur lagerichtig einzulegen, sondern auch die Verwendung falscher Rollen zu vermeiden. Zusätzlich können, wie aus Fig. 1, 2 und 4 ersichtlich ist, die Durchmesser der Lagerzapfen 5 im Bereich der Lagerflächen 8 größer als die Durchmesser der linken Lagerzapfen 4 sein, dies ist aber nicht zwingend erforderlich.The bearing pins 5 have recesses 12 on the free end faces 11, which are formed opposite to the projections 25 in the guides 21. The recesses 12 are provided with mating surfaces 9, which in contrast to the bearing surfaces 8 do not represent surfaces of revolution, but in particular flat side surfaces of end-side grooves (FIG. Fig. 1, 2, 3 . 4 , 5-right). As the figures show, the mating surfaces 9 and mating surfaces 23 on the projections 25, which are not formed as surfaces of rotation, allow a large number of different combinations if encryption between the bearing journals 5 and the guides 21 of the dispenser is desired, not only to the rollers in the correct position, but also to avoid the use of false rolls. In addition, how can Fig. 1, 2 and 4 it can be seen that the diameters of the bearing journals 5 in the area of the bearing surfaces 8 are greater than the diameters of the left bearing journals 4, but this is not absolutely necessary.

Zwischen den Lagerzapfen 4, 5 und den Führungen 20, 21 des Spenders muss ausreichend Spiel gegeben sein, um die Rollen in den Führungen nicht zu verklemmen. Da die Vorsprünge 25 in den Ausnehmungen 12 in Richtung der Rollenachse frei verschiebbar sind, sind die Lagerzapfen 5 mit Axialführungsflächen 10 versehen, die mit entsprechenden zweiten Führungsflächen 24 an den Führungen 21 zusammenwirken, um ein Herausgleiten der Lagerzapfen 5 zumindest aus den Führungen 21 zu verhindern. Die Axialführungsflächen 10 sind an den Lagerzapfen 5, insbesondere wie die Figuren zeigen, durch die der Stirnseite 11 nähere Seitenwand der Umfangsnut 7 gebildet, in die an den Führungen 21 zueinander weisende Stege 27 eingreifen, an denen die zweiten Führungsflächen 24 angeordnet sind. Axialführungsflächen 10 können aber auch an vom Umfang der Lagerzapfen 5 abstehenden zahnartigen Vorsprüngen oder dergleichen vorgesehen sein, was eine Umfangsnut erübrigt. Die Axialführungsflächen 10 und die zweiten Führungsflächen 24 liegen insbesondere in Radialebenen der Rollenachse, können aber auch Kegelflächen sein.Between the bearing pins 4, 5 and the guides 20, 21 of the dispenser must be given sufficient clearance not to jam the rollers in the guides. Since the projections 25 in the recesses 12 in the direction of the roller axis are freely displaceable, the bearing pins 5 are provided with axial guide surfaces 10 which cooperate with corresponding second guide surfaces 24 on the guides 21 to prevent sliding out of the bearing pin 5 at least from the guides 21 , The axial guide surfaces 10 are on the bearing pin 5, in particular as the figures show, 11 formed by the end face closer side wall of the circumferential groove 7, engage in the guides 21 facing each other webs 27 on which the second guide surfaces 24 are arranged. However, axial guide surfaces 10 can also be provided on protruding from the circumference of the bearing pin 5 tooth-like projections or the like, which eliminates a circumferential groove. The axial guide surfaces 10 and the second guide surfaces 24 are in particular in radial planes of the roller axis, but may also be conical surfaces.

Besonders vorteilhafte Ausführungen zeigen Fig. 2 und Fig. 5 rechts. In Fig. 2 ist die Tiefe der Ausnehmung 12 gleich wie die Länge des Endabschnittes 6, sodass der Boden 13 der Ausnehmung 12 mit der zur freien Stirnseite 11 des Lagerzapfens 5 näheren Seitenwand der Umfangsnut 7 fluchtet. In Fig. 5 rechts erstreckt sich die Ausnehmung 12 auch noch in die Umfangsnut 7. Beide Ausführungen bieten eine besonders hohe Sicherheit dafür, dass in die in Fig. 2 oder Fig. 5 rechts gezeigten Führungen 21 nur Lagerzapfen 5 in den in Fig. 2 oder Fig. 5 rechts gezeigten Ausführungen eingesetzt werden können, da es in beiden Ausführungen nicht möglich wäre, den Endabschnitt 6 eines Lagerzapfens 5 zu kürzen, um den Vorsprung 25 in der Führung 21 zu umgehen. In diesem Fall würde nämlich die Axialführungsfläche 10 wegfallen.Particularly advantageous embodiments show Fig. 2 and Fig. 5 right. In Fig. 2 the depth of the recess 12 is equal to the length of the end portion 6, so that the bottom 13 of the recess 12 is aligned with the closer to the free end face 11 of the bearing pin 5 side wall of the circumferential groove 7. In Fig. 5 on the right, the recess 12 also extends into the circumferential groove 7. Both embodiments offer a particularly high level of security in that in the in Fig. 2 or Fig. 5 Guides 21 shown on the right only bearings 5 in the in Fig. 2 or Fig. 5 shown on the right, as it would not be possible in both versions, the end portion 6 of a journal 5 to shorten to the projection 25 in the guide 21 to avoid. In this case, namely the axial guide surface 10 would be omitted.
