Description

Spender für Papier Dispenser for paper
Die Erfindung betrifft einen Spender für Papier von einer in einer Spendeposition liegenden Spenderolle, mit zwei einen Spalt definierenden Förderwalzen für die Papierbahn und mit einem beweglichen Abtastelement zur Erkennung des Papierendes.The invention relates to a dispenser for paper from a donor roller located in a dispensing position, with two gap defining conveyor rollers for the paper web and with a movable sensing element for detecting the paper end.
Bei derartigen Spendern kann mit Hilfe des Abtastelementes der bevorstehende Aufbrauch des Papiers angezeigt werden. Beispielsweise liegt das Abtastelement auf der Papierbahn zwischen der Spenderolle und den Förderwalzen lose auf, oder wird mittels einer Feder dagegen gedrückt. Die Papierbahn ist beispielsweise auf eine Kartonhülse oder einen Tragstab gewickelt, wobei das Ende an der Hülse oder am Tragstab beispielsweise durch eine Verleimung fixiert sein kann, gegebenenfalls aber auch lose gewickelt ist. Ebenso kann das Papierende lose sein, wenn die Verleimung unpräzise bzw. schlecht ausgeführt war. Da beispielsweise bei auf Rollen gewickelten Hygienepapieren auch keine Präzision oder aufwändige Verarbeitung zu erwarten ist, kann daher nicht ausgeschlossen werden, dass das Abtastelement mangels Spannung in der Papierbahn nahe seinem Ende vorzeitig Papiermangel anzeigt, obwohl noch ein paar Windungen zur Verfügung stehen. Je nach Art der Anzeige kann dies unnötigen Papierverschleiß zur Folge haben, insbesondere wenn die vorzeitige Papiermangelerkennung die Nachförderung des Papiers von einer Reserverolle auslöst.With such dispensers, the impending consumption of the paper can be indicated with the aid of the scanning element. For example, the sensing element lies loosely on the paper web between the donor roll and the feed rolls, or is pressed against it by means of a spring. The paper web is wound, for example, on a cardboard sleeve or a support rod, wherein the end may be fixed to the sleeve or the support rod, for example by gluing, but optionally also loosely wound. Likewise, the paper end may be loose if the gluing was imprecise or poorly executed. Since, for example, no hygiene or elaborate processing is to be expected in hygienic papers wound on rolls, it can not be ruled out that the scanning element will prematurely display paper shortage near its end due to a lack of tension in the paper web, although a few turns are still available. Depending on the type of display, this can result in unnecessary paper wear, especially if the premature paper shortage detection triggers the Nachförderung the paper from a reserve roll.
Die Erfindung betrifft daher auch einen Spender für Papier von einer in einer Spendeposition liegenden Spenderolle, das durch einen Spalt zwischen zweiThe invention therefore also relates to a dispenser for paper from a dispensing roll located in a dispensing position, which passes through a gap between two
Förderwalzen führbar ist, mit einer Aufnahme für eine Reserverolle, mit einer bewegbaren Halterung, der der Papieranfang der Reserverolle zuordenbar ist, und mit einem beweglichen Abtastelement für das Papierende der Spenderolle, das beiConveyor rollers is feasible, with a receptacle for a spare roll, with a movable holder, the paper beginning of the reserve roll can be assigned, and with a movable sensing element for the paper end of the donor roll, the
Erkennung des Papierendes die Halterung für das Papier der Reserverolle freigibt, so dass sich die Halterung an den Spalt annähert und den Papieranfang in den Spalt einfädelt.Detection of the end of the paper releases the holder for the paper of the reserve roll, so that the holder approaches the nip and threads the beginning of the paper into the nip.
Derartige Spender sind bereits mehrfach bekannt. Naturgemäß sind dazu dieSuch donors are already known several times. Naturally, these are the
Papierwege der Spenderolle von jenen der Reserverolle getrennt und gehen erst unmittelbar vor dem Spalt der beiden Förderwalzen ineinander über, da ja nach Aufbrauch der Spenderolle eine automatisierte weitere Papierabgabe erfolgen soll. Das Abtastelement ist daher dem Papierweg der Spenderolle zugeordnet.Paper paths of the donor roll separated from those of the reserve roll and only just before the gap of the two conveyor rollers into each other, because after Abusing the donor role an automated further paper delivery should be made. The scanning element is therefore associated with the paper path of the donor roll.
In einer aus der US 4,165,138 bekannten Ausführung weist jene der beiden Förderwalzen, die über einen größeren Teil ihres Umfangs von der Papierbahn der Spenderolle umschlungen ist, eine Umfangsnut auf, der das Abtastelement zugeordnet ist. Ist die Papierbahn zu Ende, fällt das Abtastelement in die Nut und löst die Annäherung der Halterung für den Papieranfang der Reserverolle aus. Das Abtastelement ist dabei so angeordnet, dass es in der Umfangsnut verbleiben kann, wenn das Papier von der Reserverolle eingefädelt und gefördert wird. Irgendwann können dann der leere Rollenträger der früheren Spenderolle entnommen, die in Verwendung stehende Reserverolle in die Position der Spenderolle umgelagert und eine neue Reserverolle eingelegt werden. Dabei ist es erforderlich, das Abtastelement aus der Umfangsnut herauszuschwenken und für die neue Spenderolle zu aktivieren, in dem es auf deren Papierbahn aufgelegt wird. Weiters ist es erforderlich, die Halterung für den Papieranfang der neuen Reserverolle in ihre Warteposition zurückzuschwenken und den Papieranfang an der Halterung festzulegen, sodass der Papierspender wieder eine funktionsfähige Nachführeinrichtung aufweist, wenn die Spenderolle leer ist.In an embodiment known from US Pat. No. 4,165,138, that of the two conveying rollers, which is wrapped around the paper web of the dispensing roll over a larger part of its circumference, has a circumferential groove, which is associated with the scanning element. If the paper web is over, the scanning element falls into the groove and triggers the approach of the holder for the beginning of the paper reserve roll. The scanning element is arranged so that it can remain in the circumferential groove when the paper is threaded from the reserve roll and conveyed. At some point, the empty roll carrier can then be removed from the former donor roll, the spare roll in use can be relocated to the position of the donor roll and a new reserve roll can be inserted. In this case, it is necessary to swivel the scanning element out of the circumferential groove and to activate it for the new dispensing roll, in which it is placed on its paper web. Furthermore, it is necessary to zurückzuschwenken the holder for the beginning of the paper of the new spare roll in their waiting position and set the beginning of the paper on the holder, so that the paper dispenser again has a functional tracking device when the dispensing roll is empty.
Die Erfindung hat es sich nun zur Aufgabe gestellt, bei derartigen Papierspendern vorzeitige Papierendeanzeigen zu vermeiden und erreicht dies dadurch, dass das Abtastelement in Papierförderrichtung nach dem Spalt zwischen den beiden Förderwalzen angeordnet ist. Durch die Anordnung des Abtastelements nach dem Spalt bleibt die Spannung in der Papierbahn trotz eines losen Wicklungsendes erhalten, da es zwischen den Förderwalzen nicht durchrutschen kann. Die Papierendeerkennung erfolgt daher unmittelbar nach der Förderung der Papierbahn durch die beiden Förderwalzen. Eine Fehlauslösung ist dadurch praktisch ausgeschlossen.The invention has now taken on the task of avoiding premature end-of-paper displays in such paper dispensers and achieves this by the scanning element is arranged in the paper conveying direction after the gap between the two conveyor rollers. The arrangement of the sensing element after the gap, the tension in the paper web is maintained despite a loose winding end, since it can not slip between the conveyor rollers. The paper end detection is therefore carried out immediately after the promotion of the paper web through the two conveyor rollers. A false trip is practically impossible.
Wenn der Spender eine Reserverolle aufweist, deren Papieranfang sich bei Erkennung des Papierendes in den Spalt einfädelt, so ist zusätzlich durch die Anordnung des Abtastelementes nach dem Spalt der Raum zwischen der Reserverolle und der Spenderolle frei und die Übergabe der Rolle wird nicht behindert. Das Abtastelement liegt an einer Stelle, in der es weiterhin die Papierbahn der Spenderolle abtasten kann, aber für den Wechsel der Reserverolle nicht bewegt werden muss, da es nicht mehr im Weg der wechselnden Reserverolle liegt.If the dispenser has a reserve roll whose paper start threading into the gap upon detection of the paper end, then the space between the reserve roll and the donor roll is also free by the arrangement of the scanning element after the gap and the transfer of the role is not hindered. The scanning element is located at a position where it can continue to scan the paper web of the donor roll, but it does not have to be moved to change the reserve role, because it is no longer in the way of the changing reserve roll.
In einer bevorzugten Ausführung ist vorgesehen, dass die beiden Förderwalzen im Wesentlichen übereinander angeordnet sind und die untere Förderwalze einen wesentlich größeren Durchmesser als die obere Förderwalze sowie eine Umfangnut aufweist. Da die untere Förderwalze in der Breite die obere Walze überragt, schafft dies die Möglichkeit, durch das Abtastelement die Papierbahn der Spenderolle direkt neben der kleineren Förderwalze abzutasten, wobei es bei Erkennung des Papierendes untere Schwerkrafteinfluss in die Umfangsnut fällt.In a preferred embodiment it is provided that the two conveyor rollers are arranged substantially one above the other and the lower conveyor roller has a substantially larger diameter than the upper conveyor roller and a peripheral groove. Since the lower conveyor roller projects beyond the upper roller in width, this makes it possible to scan through the scanning element the paper web of the dispensing roller directly next to the smaller conveyor roller, and upon detection of the paper end, it falls under the influence of gravity into the peripheral groove.
Die Anordnung des Abtastelementes außerhalb des von der Reserverolle beim Wechsel in die Spendeposition benötigten Raumes erlaubt eine Automatisierung dieses Wechsels, ohne dass das Servicepersonal händisch eingreift. In bevorzugter Ausführung ist daher hiefür auch ein Rückstellelement vorgesehen, das das Abtastelement, nachdem es das Papierende erkannt hat, in die Ausgangslage zurückstellt. Dadurch ist der Papierweg nach dem Spalt nach der Papierendeerkennung wieder geöffnet, sodass die übernommene Papierbahn der Reserverolle problemlos gefördert werden kann. Zu einem beliebig eingestellten Zeitpunkt kann dann ohne händische Hilfe die Reserverolle nach unten in die Spendeposition fallen oder rutschen, aus der dann ihre Papierbahn weiter abgezogen wird.The arrangement of the sensing element outside of the space required by the reserve roll when changing to the dispensing position allows automation of this change without the service staff manually intervene. In a preferred embodiment, therefore, a return element is also provided for this purpose, which returns the scanning element, after it has detected the paper end, to the starting position. As a result, the paper path is opened again after the gap after paper end detection, so that the taken-over paper web of the reserve roll can be conveyed easily. At any set time can then fall without manual help, the reserve roll down into the dispensing position or slip, from which then their paper web is further deducted.

Für das Personal verbleibt dadurch nur das Anheben der Halterung, um den neuen Papieranfang zu fixieren, wofür diese in einer bevorzugten Ausführung durch einen schwenkbaren Bügel gebildet ist, zu dessen Quersteg Dorne vorgesehen sind, auf die der Papieranfang aufdrückbar ist. Die Förderwalzen weisen eine griffige Oberfläche, beispielsweise Gummiringe od. dgl. auf, die das aufgedornte Papier verlässlich lösen und in den Spalt einziehen.Return spring, utilized and thus a functionally important step is not dependent on the skill of the service personnel. For the staff remains thereby only the lifting of the holder to fix the new paper beginning, for which this is formed in a preferred embodiment by a pivoting bracket, to the transverse web mandrels are provided on the beginning of the paper can be pressed. The conveyor rollers have a non-slip surface, such as rubber rings od. Like. On, reliably solve the thinned paper and move into the gap.
In einer ersten Ausführung kann das Abtastelement um eine Achse schwenkbar, und das Rückstellelement exzentrisch am Abtastelement angelenkt sein.In a first embodiment, the scanning element can pivot about an axis, and the restoring element can be articulated eccentrically on the scanning element.
In einer zweiten Ausführung ist vorgesehen, dass das Abtastelement um eine Achse schwenkbar ist und das Rückstellelement durch einen am Abtastelement abstehenden Hebel gebildet ist, der mit zwei an der Halterung vorgesehenen Anschlägen zusammenwirkt.In a second embodiment it is provided that the sensing element is pivotable about an axis and the restoring element is formed by a protruding lever on the sensing element, which cooperates with two stops provided on the holder.
Erfindungsgemäß kann die Rückstellung des Abtastelementes durch die sich an den Spalt annähernde Halterung für den Papieranfang der Reserverolle auch dann vorgesehen sein, wenn das Abtastelement an einer anderen Stelle auf dem Weg der Papierbahn der Spenderolle vorgesehen ist.According to the invention, the provision of the scanning element can be provided by the approach to the gap approaching holder for the beginning of paper reserve roll even when the sensing element is provided at a different location on the way the paper web of the donor roll.

Das Förderwalzenpaar weist eine in der gezeigten Ausführung kleinere Förderwalze 4 auf, über die die Papierbahn 25 der Spenderolle 10 in den Spalt 6 mit der zweiten größeren und unterhalb der Förderwalze 4 gelagerten Förderwalze 5 geführt ist, die die Messeranordnung enthalten kann.3 to 9 different positions of components essential to the invention, and Fig. 10 to 12 different positions of components essential to the invention in a further embodiment. A paper dispenser according to FIGS. 1 and 2 has a housing, in the lower region of which a receiving space for a dispensing roll 10 and in particular a knife assembly comprising conveying roller pair 4, 5 are arranged, which is manually controlled by pulling on the paper, by an external crank or preferably sensor-controlled can be driven by an electric motor. The conveyor roller pair has a smaller in the illustrated embodiment conveyor roller 4, over which the paper web 25 of the dispensing roll 10 is guided in the gap 6 with the second larger and below the conveyor roller 4 mounted conveying roller 5, which may contain the knife assembly.
Die zweite Förderwalze 5 weist eine Umfangsnut 7 auf, der ein Abtastelement 11 zugeordnet ist, das um eine Achse 9 schwenkbar in Förderrichtung F nach dem Spalt 6 gelagert ist. Das Abtastelement 11 kann mit einer im Winkel hochstehenden, nur schematisch in Fig. 2 angedeuteten Lasche 8 versehen sein, über die die Rückstellung des Abtastelementes 11 in die in Fig. 1 gezeigte Position erfolgen kann.The second conveyor roller 5 has a circumferential groove 7, which is associated with a scanning element 11 which is mounted about an axis 9 pivotally in the conveying direction F for the gap 6. The sensing element 11 may be provided with an upwardly inclined, only schematically indicated in Fig. 2 tab 8, via which the provision of the sensing element 11 can be carried out in the position shown in Fig. 1.
Ein Papierspender nach den Fig. 3 bis 9 weist ein Gehäuse 1 auf, das mit einer hochschwenkbaren, nicht gezeigten Verkleidung versehen ist. Auch hier sind im unteren Bereich des Spenders ein Aufnahmeraum für eine Spenderolle 10 und ein insbesondere eine Messeranordnung umfassendes Förderwalzenpaar angeordnet, das händisch durch Zug am Papier, durch eine äußere Kurbel oder bevorzugt sensorgesteuert durch einen elektrischen Motor angetrieben wird.A paper dispenser according to FIGS. 3 to 9 has a housing 1, which is provided with a swiveling, not shown, lining. Again, a receiving space for a dispensing roll 10 and a particular knife assembly comprising a pair of conveyor rollers are arranged in the lower part of the dispenser, which is manually driven by train on paper, by an external crank or preferably sensor-controlled by an electric motor.
Die zweite Förderwalze 5 weist eine Umfangsnut 7 auf, der ein Abtastelement 11 zugeordnet ist, das um eine Achse 9 schwenkbar in Förderrichtung nach dem Spalt 6 gelagert ist. Das Abtastelement 11 ist mit einer im Winkel hochstehenden Steuerlasche 8 versehen, mittels dem die Bewegung des Abtastelements 11 beim Eintreten in die Umfangsnut 7 übertragen wird.The second conveyor roller 5 has a circumferential groove 7, which is associated with a scanning element 11 which is mounted pivotably about an axis 9 in the conveying direction after the gap 6. The sensing element 11 is provided with an upwardly projecting control flap 8, by means of which the movement of the sensing element 11 is transmitted upon entering the circumferential groove 7.
Der Papieranfang 24 der Reserverolle 13 wird nach dem Einlegen der Rolle in einen oberen Aufnahmeraum an Dornen 16 einer Halterung 14 festgelegt, die durch einen um eine Achse 17 schwenkbaren Bügel gebildet ist, und von einem um eine Achse 19 schwenkbaren Rasthebel 18 auf Abstand vom Spalt 6 zwischen den Förderwalzen 4, 5 gehalten ist. Das vordere Ende des Rasthebels 18 liegt auf einem Vorsprung 22 (Fig. 7, 8) eines Seitenteiles der Halterung 14 und das hintere Ende mit einer Schräge 21 (Fig. 7, 8) auf der Steuerlasche 8 des Abtastelementes 11 auf. Der Seitenteil der Halterung 14 trägt weiters eine Nase 20, die bei Annäherung an den Spalt 6 auf das in Form eines Schiebers ausgebildete federbeaufschlagte Rückstellelement 12 trifft, dessen anderes Ende an der Steuerlasche 8 des Abtastelementes 11 angelenkt ist.The paper beginning 24 of the reserve roll 13 is determined after inserting the role in an upper receiving space on thorns 16 of a holder 14 which is formed by a pivotable about an axis 17 bracket, and a pivotable about an axis 19 locking lever 18 at a distance from the gap 6 between the conveyor rollers 4, 5 is held. The front end of the locking lever 18 is located on a projection 22 (Fig. 7, 8) of a side part of the holder 14 and the rear end with a slope 21st (Fig. 7, 8) on the control lug 8 of the sensing element 11. The side part of the holder 14 also carries a nose 20 which, when approaching the gap 6, strikes the spring-loaded return element 12 in the form of a slider, the other end of which is articulated on the control lug 8 of the scanning element 11.
Die Funktion wird nun mit Bezug auf die Fig. 4 bis 9 näher erläutert: Wie aus Fig. 4 ersichtlich ist, ist die Papierbahn 25 von der Spenderolle 10 über die Förderwalze 4 durch den Spalt 6 und über die Förderwalze 5 geführt, wobei nach dem Spalt 6 das Abtastelement 11 auf der Papierbahn 25 aufliegt. Ist das Papier zu Ende, fällt das Abtastelement 11 unter Wirkung der Schwerkraft und unterstützt durch die dem Rückstellelement 12 zugeordnete Feder 23 in die Umfangsnut 7 der Förderwalze 5 (Fig. 5). Dabei schwenkt die hochstehende Steuerlasche 8 nach vorne (in der Zeichnung links), schiebt das Rückstellelement 12 mit Unterstützung der Feder 23 nach vorne und drückt das hintere Ende des zweiarmigen Rasthebels 18 hoch, dessen vorderes Ende vom Vorsprung 22 am Seitenteil der Halterung 14 abrutscht. Die Halterung 14 kann daher durch Schwerkraft und unterstützt durch die gezeigte Zugfeder um die Achse 17 schwenken, sodass die keilförmige Einfädelnase des Quersteges 15 der Halterung 14 sich mit dem daran befestigten Papieranfang der Reserverolle 13 am Spalt 6 annähert. Bevor dieser erreicht wird, trifft die Nase 20 auf das vorgeschobene Rückstellelement 12 und schiebt dieses wieder in die Startposition (Fig. 6, 8) zurück. Da das Rückstellelement 12 an der Steuerlasche 8 angelenkt ist, schwenkt diese nach hinten (in der Zeichnung rechts) und hebt das Abtastelement 11 aus der Umfangsnut 7 der Förderwalze 5. Sobald die Einfädelnase des Quersteges 15 den Spalt 6 erreicht hat, wird der Papieranfang 24 von der insbesondere zumindest bereichsweise eine Gummibeschichtung aufweisenden Oberfläche der beiden Förderwalzen ergriffen, von den Dornen 16 gelöst und in den Spalt eingezogen. Dank der Rückstellung des Abtastelementes 11 ist der weitere Weg für die Papierbahn 24 frei. Fig. 8 und 9 zeigen diese Stellungen in Seitenansicht und im Querschnitt.The function will now be explained in more detail with reference to Figs. 4 to 9: As can be seen from Fig. 4, the paper web 25 is guided by the donor roller 10 via the feed roller 4 through the gap 6 and the conveying roller 5, wherein after Gap 6, the scanning element 11 rests on the paper web 25. If the paper is over, the sensing element 11 falls under the action of gravity and supported by the return element 12 associated spring 23 in the circumferential groove 7 of the conveyor roller 5 (Fig. 5). The upstanding control flap 8 pivots forward (left in the drawing) pushes the return element 12 with the support of the spring 23 to the front and pushes the rear end of the two-armed latching lever 18 high, the front end of the projection 22 on the side part of the holder 14 slips off. The holder 14 can therefore pivot by gravity and supported by the tension spring shown about the axis 17, so that the wedge-shaped threading of the cross bar 15 of the holder 14 with the attached paper beginning of the reserve roll 13 at the gap 6 approaches. Before this is achieved, the nose 20 hits the advanced return element 12 and pushes it back into the starting position (FIGS. 6, 8). Since the return element 12 is hinged to the control plate 8, this pivots to the rear (right in the drawing) and lifts the sensing element 11 from the circumferential groove 7 of the conveyor roller 5. Once the threading of the crosspiece 15 has reached the gap 6, the paper top 24th taken from the particular at least partially a rubber coating having surface of the two conveyor rollers, released from the mandrels 16 and fed into the gap. Thanks to the provision of the sensing element 11, the further path for the paper web 24 is free. 8 and 9 show these positions in side view and in cross section.
Nach einer bestimmten Verwendungszeit hat sich der Durchmesser der Reserverolle 13 so weit verringert, dass sie entlang der Führungsbahn 2 aus der Warteposition nach unten in den Aufnahmeraum fallen bzw. rutschen kann (Fig. 6). Da im Übergabebereich 27 (Fig. 4, 5) keine störenden Einbauten sind und das für die Papierbahn 25 benötigte Abtastelement 11 außerhalb liegt, kann dieser Wechsel ohne Zutun einer Serviceperson erfolgen. Fig. 5 zeigt den Bereich P, in dem sich die Papierbahn von 24 nach 25 verlagert. Der automatische Wechsel kann beispielsweise durch eine Durchmesserabtastung der Reserverolle 13 in der oberen Position erfolgen, die dann bei entsprechend verringertem Durchmesser in der Führungsbahn 2 nach unten rutscht oder fällt.After a certain period of use, the diameter of the reserve roll 13 has decreased so far that it can fall or slip along the guideway 2 from the waiting position down into the receiving space (FIG. 6). Since in the transfer area 27 (FIGS. 4, 5) there are no disturbing installations and the scanning element 11 required for the paper web 25 lies outside, this change can take place without the intervention of a service person. Fig. 5 shows the area P in which the Paper web shifted from 24 to 25. The automatic change can be done, for example, by a diameter scan of the reserve roll 13 in the upper position, which then slips or falls with a correspondingly reduced diameter in the guideway 2 down.
Fig. 10 bis 12 zeigen wesentliche Teile einer dritten Ausführung des Spenders 1. Dargestellt sind die beiden den Spalt 6 begrenzenden Förderwalzen 4, 5, von denen die größere Förderwalze eine Messereinrichtung enthält, die die Papierbahn in Abschnitte schneidet. Das Abtastelement 11 ist um die Achse 9 drehbar gelagert und fällt am Ende der in den Fig. 10 bis 12 nicht gezeigten Papierbahn in die Umfangsnut 7 der Förderwalze. Auch bei dieser Ausführung wird die Papierbahn in Papierförderrichtung F nach dem Spalt 6 abgetastet.Fig. 10 to 12 show essential parts of a third embodiment of the dispenser 1. Shown are the two the gap 6 delimiting conveyor rollers 4, 5, of which the larger conveyor roller includes a knife device which cuts the paper web into sections. The scanning element 11 is rotatably mounted about the axis 9 and falls at the end of the paper web, not shown in FIGS. 10 to 12 in the circumferential groove 7 of the feed roller. Also in this embodiment, the paper web is scanned in the paper conveying direction F after the gap 6.
Die Halterung 14 für den Anfang der Papierbahn der Reserverolle ist wie beschrieben bügelartig ausgebildet. An zumindest einem Seitenteil 23 der Halterung 14 sind zweiThe holder 14 for the beginning of the paper web of the reserve roll is bow-shaped as described. At least one side part 23 of the holder 14 are two
Anschläge 28 und 29 ausgebildet. In der in Fig. 10 gezeigten Warteposition liegt derStops 28 and 29 formed. In the waiting position shown in Fig. 10 is the
Seitenteil 23 auf dem vom Abtastelement 11 hochstehenden Rückstellelement 12 auf und der Quersteg 15 wird mit Abstand zum Spalt 6 gehalten. Sobald das Papierende der Spenderolle 10 erkannt wird, fällt das Abtastelement 11 in die Umfangsnut 7 und das Rückstellelement 12 schwenkt nach vorne bzw. in Fig. 10 nach links.Side part 23 on the sensing element 11 upstanding restoring element 12 and the crossbar 15 is held at a distance from the gap 6. As soon as the paper end of the dispensing roll 10 is detected, the scanning element 11 falls into the circumferential groove 7 and the return element 12 pivots forwards or in FIG. 10 to the left.
Die Halterung 14 wird dadurch freigegeben (Fig. 11) und schwenkt um die Achse 17 nach unten, wobei kurz nach der Auslösung der zweite Anschlag 28 auf das Rückstellelement 12 trifft, sodass dieses vor Abschluss der Schwenkbewegung der Halterung 14 zurückgeschwenkt und dadurch das Abtastelement 11 wieder aus der Umfangsnut 7 angehoben wird (Fig. 12). Der Weg für die von der Halterung 14 eingefädelte Papierbahn der Reserverolle ist dadurch wieder frei.The holder 14 is thereby released (FIG. 11) and pivots down about the axis 17, wherein shortly after the triggering of the second stop 28 strikes the return element 12, so that this swung back before completion of the pivoting movement of the holder 14 and thereby the scanning element 11th is raised again from the circumferential groove 7 (Fig. 12). The way for the threaded from the holder 14 paper web of reserve roll is thereby free again.
Beim Einlegen einer neuen Reserverolle wird die Halterung 14 aus der Position nach Fig. 12 wieder hochgeschwenkt, sodass das Ende des Rückstellelementes 12 wieder unter den Anschlag 29 zu liegen kommt. Das freie Ende des Rückstellelementes 12 ist senkrecht zur Zeichenebene federnd, sodass es bei der Rückschwenkbewegung dem Anschlag 29 ausweichen kann. When inserting a new reserve roll, the holder 14 is pivoted from the position of FIG. 12 again, so that the end of the return element 12 comes to rest under the stop 29 again. The free end of the return element 12 is perpendicular to the plane of the spring, so that it can escape the stop 29 in the return pivoting movement.
