Description

Die Erfindung betrifft eine Vorrichtung zur Ausgabe von Papierabschnitten vorgegebener Länge mit einer durch Ziehen an einem Papierbahnende betätigbaren Einrichtung zum teilweisen Abtrennen der Papierabschnitte von der auf einer Rolle aufgewickelten Papierbahn und zum griffbereiten Bereitstellen des nach Freigabe des abgetrennten Papierabschnittes nachfolgenden Papierbahnendes, welche eine Walze mit einem exzentrisch zur Walzenachse bewegbaren Messer mit einer die teilweise Abtrennung der Papierabschnitte von der auf der Rolle aufgewickelten Papierbahn bewirkenden Schneidekante aufweist.The invention relates to a device for dispensing paper sections of a predetermined length with a device which can be actuated by pulling on a paper web end for partially separating the paper sections from the paper web wound on a roll and for making available the paper web end that follows after release of the separated paper section, which roller has a roller Knife movable eccentrically to the roller axis with a cutting edge which partially separates the paper sections from the paper web wound on the roll.

Bei bekannten Vorrichtungen dieser Art (FR-A-2 291 939 und GB-A-837194) ist zum vollständigen Abtrennen des teilweise abgetrennten Papierabschnittes ein gesonderter Abreißvorgang erforderlich, der vom Benutzer der Vorrichtung ausgeführt werden muß. Dies erschwert die Handhabung der bekannten Vorrichtung.In known devices of this type (FR-A-2 291 939 and GB-A-837194), a separate tear-off process is required to completely remove the partially separated paper section, which must be carried out by the user of the device. This complicates the handling of the known device.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine Vorrichtung dieser Art zu schaffen, bei welcher die teilweise abgetrennten Papierabschnitte durch den gleichen, das teilweise Abtrennen bewirkenden Ziehvorgang automatisch vollständig abgetrennt werden.The object of the present invention is to provide a device of this type in which the partially separated paper sections are automatically completely separated by the same pulling process which causes the partial separation.

Diese Aufgabe wird bei einer Vorrichtung der eingangs genannten Art gemäß der Erfindung dadurch gelöst, daß die durch Ziehen an einem Papierbahnende betätigbare Einrichtung eine Vorrichtung zum kurzzeitigen Arretieren der Walze aufweist, die aus einem drehfest an der Stirnseite der Walze angeordneten Nocken und Anschlag und außerdem aus einem an einem Gehäuseteil gelagerten zweiarmigen Hebel besteht, und daß ein Ende des Hebels mit einer Zugfeder verbunden ist und das andere Ende des Hebels mit dem Nocken und Anschlag in Eingriff bringbar ist. Bei gleichbleibendem Zug des Benutzers an der Papierbahn wird erfindungsgemäß der herausgezogene Papierabschnitt an der teilweise bereits abgetrennten Schnittlinie von der nachfolgenden Papierbahn vollständig abgetrennt. Die erfindungsgemäße Vorrichtung ist einfach aufgebaut, äußerst funktionssicher und leicht zu handhaben.This object is achieved in a device of the type mentioned according to the invention in that the device which can be actuated by pulling on a paper web end has a device for briefly locking the roller, which consists of a cam and stop arranged in a rotationally fixed manner on the end face of the roller and also from there is a two-armed lever mounted on a housing part, and that one end of the lever is connected to a tension spring and the other end of the lever can be brought into engagement with the cam and stop. If the user does not pull on the paper web, according to the invention, the paper section that is pulled out is completely separated from the subsequent paper web at the cutting line that has already been partially cut off. The device according to the invention is simple in construction, extremely reliable and easy to handle.

Aus der US-A-2 886 226 ist eine Vorrichtung zum kurzzeitigen Arretieren einer Ausgabewalze zum vollständigen Abtrennen eines Papierabschnittes bekannt, der über eine Perforationslinie mit der nachfolgenden Papierbahn verbunden ist. Hierbei wird eine Papierbahn mit vorgefertigten Perforationslinien verwendet. Die Ausgabewalze steht hierbei mit einer Andrückwalze in Verbindung, um insbesondere auch zu gewährleisten, daß durch die hieran speziell angepaßte konstruktive Ausgestaltung der Vorrichtung zum kurzzeitigen Arretieren ausschließlich der letzte Papierabschnitt von der verbleibenden Papierbahn abgetrennt wird.From US-A-2 886 226 a device for briefly locking an output roller for completely severing a paper section is known, which is connected to the subsequent paper web via a perforation line. Here, a paper web with prefabricated perforation lines is used. The output roller is connected to a pressure roller in order to ensure, in particular, that only the last paper section is separated from the remaining paper web by the specially designed structural design of the device for brief locking.

Im nachfolgenden wird eine Ausführungsform der vorliegenden Erfindung in Verbindung mit der Zeichnung beschrieben. Darin zeigt

  • Fig. 1 einen schematischen Längsschnitt durch eine Vorrichtung gemäß der Erfindung,
  • Fig. 2 eine teilweise weggebrochene perspektivische Ansicht einer Ausführungsform der Messerwalze,
  • Fig. 3 einen Querschnitt durch die Messerwalze gemäß Fig. 2 mit verschiedenen, gestrichelt dargestellten Positionen des Messers im Schneidbereich und
  • Fig. 4 eine Seitenansicht der Vorrichtung zum kurzzeitigen Arretieren der Messerwalze.
In the following, an embodiment of the present invention is described in connection with the drawing. It shows
  • 1 shows a schematic longitudinal section through a device according to the invention,
  • 2 is a partially broken perspective view of an embodiment of the knife roller,
  • 3 shows a cross section through the knife roller according to FIG. 2 with different positions of the knife in the cutting area and shown in broken lines
  • Fig. 4 is a side view of the device for briefly locking the knife roller.

In Fig. 1 ist eine Vorrichtung 1, auch Spender genannt, zur Ausgabe von Papierabschnitten mit einem z. B. an einer Wand 2 befestigten Gehäuse 3, einer Papierrolle 4, einer Papierbahn 5, einer Umlenkrolle 6, einer Messerwalze 7 und einer keilförmigen Führungseinrichtung 8 zum Anpressen der Papierbahn an die Messerwalze im Schneidbereich gezeigt. Wie aus den Fig. 2 und 3 hervorgeht, weist die Walze 7 ein Messer 9 auf, das auf einer exzentrisch zur Walzenachse 10 angeordneten, einstückig mit dieser ausgebildeten Achse 11 im Inneren der Walze 7 drehbar gelagert ist und beim Drehen der Walze 7 durch einen im Walzenmantel vorgesehenen Schlitz 12 mitgenommen wird. Hierbei beschreibt das Messer 9 eine Bewegungsbahn 13, wobei in Fig. 3 drei verschiedene Positionen des Messers 9 gestrichelt dargestellt sind. Die Tiefe des Messers 9 entspricht hierbei ungefähr dem Radius der Messerwalze 7 plus der Exzentrizität der Achse 11 in bezug auf die Achse 10, so daß das Messer auf seiner gesamten Bewegungsbahn vom Schlitz 12 mitgenommen wird. Das Messer 9 weist eine sägeblattartige Schneidekante 14 auf. Der kurzwelligen Sägeblattform ist hierbei eine Wellenform mit größerer Wellenlänge überlagert, derart, daß bei Durchlaufen der Bewegungsbahn 13, d. h. im Schneidbereich, die Papierbahn 5 jeweils nur im Amplitudenbereich dieser Wellenform, d. h. perforationsartig, geschnitten wird.In Fig. 1, a device 1, also called a dispenser, for dispensing sections of paper with a z. B. on a wall 2 attached housing 3, a paper roll 4, a paper web 5, a guide roller 6, a knife roller 7 and a wedge-shaped guide device 8 for pressing the paper web against the knife roller in the cutting area. As can be seen from FIGS. 2 and 3, the roller 7 has a knife 9, which is rotatably mounted inside the roller 7 on an eccentric to the roller axis 10, integrally formed with this axis 11 and when the roller 7 is rotated by a provided in the roll shell slot 12 is taken. Here, the knife 9 describes a movement path 13, three different positions of the knife 9 being shown in broken lines in FIG. 3. The depth of the knife 9 corresponds approximately to the radius of the knife roller 7 plus the eccentricity of the axis 11 with respect to the axis 10, so that the knife is carried along its entire path of movement by the slot 12. The knife 9 has a saw blade-like cutting edge 14. The short-wave saw blade shape is superimposed on a wave shape with a larger wavelength, such that when it traverses the movement path 13, i. H. in the cutting area, the paper web 5 only in the amplitude range of this waveform, d. H. perforation-like, is cut.

In Fig. 4 ist die an mindestens einer Stirnseite der Walze 7 angeordnete Vorrichtung zum kurzzeitigen Arretieren der Walze 7 gezeigt. An einem Gehäuseteil 15 ist an einem Lagerpunkt 16 ein zweiarmiger Hebel 17 drehbar gelagert. Ein Ende 18 des Hebels 17 ist mit einer Zugfeder 19 verbunden, die mit ihrem anderen Ende am Gehäuseteil 15 befestigt ist. Das andere Ende 20 des Hebels 17 weist einen Stift 21 auf. Zwischen dem Ende 20 und dem Lagerpunkt 16 ist der Hebel 17 in einem vertikalen Längsschlitz 22 des Gehäuseteils 15 geführt. An der Stirnseite der Walze 7, vorzugsweise an einem fest mit der Walze verbundenen Handrad 23, ist ein Nocken 24 und ein Anschlag 25 befestigt. Diese Vorrichtung funktioniert folgendermaßen: Wenn die Papierbahn 5 aus der Vorrichtung 1 herausgezogen wird, dreht sich die Walze 7 und damit der Nocken 24 und der Anschlag 25 in der Stirnansicht der Fig.4 im Uhrzeigersinn in Pfeilrichtung. Beim Herausziehen der Papierbahn 5 befindet sich der Hebel 17 und damit der Stift 21 zunächst in der schematisch strichpunktiert dargestellten Position. Durch den Nocken 24 wird der Stift 21 und damit der Hebel 17 in die in Fig. 4 gezeigte Position im Uhrzeigersinn um den Lagerpunkt 16 verschwenkt. Am Ende der Nockenbahn trifft der Stift 21 auf den Anschlag 25, wodurch die Bewegung der Walze 7 und damit der Papierbahn 5 kurzzeitig angehalten und der Papierabschnitt ruckartig abgerissen wird. Sofort nach der Arretierung wird die Walze 7 und damit die Papierbahn 5 wieder freigegeben, indem der Hebel 17 mit Hilfe der Zugfeder 19 in seine schematisch strichpunktiert dargestellte Ausgangsposition zurückgeschwenkt wird. Die Rückschwenkung wird durch den Längsschlitz 22 begrenzt.4 shows the device arranged on at least one end face of the roller 7 for briefly locking the roller 7. A two-armed lever 17 is rotatably mounted on a housing part 15 at a bearing point 16. One end 18 of the lever 17 is connected to a tension spring 19 which is fastened at the other end to the housing part 15. The other end 20 of the lever 17 has a pin 21. The lever 17 is guided in a vertical longitudinal slot 22 of the housing part 15 between the end 20 and the bearing point 16. A cam 24 and a stop 25 are fastened to the end face of the roller 7, preferably to a handwheel 23 which is firmly connected to the roller. This device works as follows: When the paper web 5 leaves the device 1 is pulled out, the roller 7 and thus the cam 24 and the stop 25 rotates clockwise in the direction of the arrow in the front view of FIG. When the paper web 5 is pulled out, the lever 17 and thus the pin 21 are initially in the position shown schematically in broken lines. By means of the cam 24, the pin 21 and thus the lever 17 are pivoted clockwise about the bearing point 16 into the position shown in FIG. 4. At the end of the cam path, the pin 21 hits the stop 25, as a result of which the movement of the roller 7 and thus the paper web 5 is briefly stopped and the paper section is torn off suddenly. Immediately after the locking, the roller 7 and thus the paper web 5 are released again by the lever 17 being pivoted back into its schematically dot-dashed starting position by means of the tension spring 19. The backward pivoting is limited by the longitudinal slot 22.
