Die Erfindung betrifft eine Aufwickeleinrichtung für bandförmiges Material, insbesondere fotografisches Kopiermaterial, mit Einfädelung des Bandanfangs durch einen Führungskanal in einen Schlitz eines drehbaren Wickelkerns,, wobei nach Patent ....... («= deutsche Patentanmeldung P 21 65 499.9) auf den Wickelkern eine abziehbare geschlitzte Hülse aufsteckbar ist und. der Wickelkern über eine in eine Verzahnung eingreifende Schnecke angetrieben ist, welche abschwenkbar gelagert ist.The invention relates to a winding device for tape-shaped material, in particular photographic copy material, with threading of the beginning of the tape through a guide channel into a slot of a rotatable winding core, whereby according to the patent ....... («= German Patent application P 21 65 499.9) a removable slotted sleeve can be attached to the winding core and. the winding core via an in a gear engaging worm is driven, which is pivotably mounted.
Bei der Ausbildung der eingangs beschriebenen Aufwickeleihrichtung als transportable Kassette tritt das Problem auf, daß beim Transport der Kassetten sich die schweren Rollen innerhalb der Kassette in Bewegung setzen und evtl. das aus der EinlaufÖffnung vorstehende Ende des Kopiermaterials in der Kassette verschwindet, so daß ein Anhängen des Papierbandes an entsprechende Fördereinrichtungen einer Entwicklungsmaschine nur mit Schwierigkeiten möglich ist.In the formation of the winding direction described above As a portable cassette, there is a problem that when the cassettes are transported, the heavy rollers within the cassette set in motion and possibly the one protruding from the inlet opening The end of the copy material in the cassette disappears, so that the paper tape can be attached to corresponding conveyors a developing machine is only possible with difficulty.
Ziel der Erfindung ist es, die Kassette mit der oben beschriebenen Aufwickeleinrichtung so auszugestalten, daß während eines Transportes eine Drehung der Rolle unter Massenkräften nicht möglich ist,The aim of the invention is to provide the cassette with the one described above Design the winding device so that during transport a rotation of the roller is not possible under inertia forces,

Eine Abwickeleinrichtung der eingangs genannten Art st gemäß der Erfindung dadurch gekennzeichnet, daß die Schnecke selbsthemmend ist, vorzugsweise der Steigungswinkel kleiner 10°.An unwinding device of the type mentioned st according to the Invention characterized in that the worm is self-locking, preferably the pitch angle less than 10 °.
Die selbsthemmende Schnecke, die urater ihrem Eigengewicht in die entsprechende Zahnung des Schneckenrades an dem Wickelkern einfällt und in dieser Stellung selbsttätig verriegelt gehalten bleibt, wirkt als automatische Bremse, wenn die Kassette von dem Antrieb am Kopiergerät abgekoppelt ist. Eine Drehung der Rolle während des Transportes der Kassette ist dann aieht möglich.The self-locking snail, which urater its own weight in the corresponding toothing of the worm wheel occurs on the winding core and remains automatically locked in this position, acts as an automatic brake when the cassette is on from the drive Copier is disconnected. A rotation of the roller while the cassette is being transported is then also possible.
Weitere Einzelheiten und Vorteile ergeben sich aus den Un t er an spr liehen im Zusammenhang eines Ausführungsbeispiels, das anhand einer Figur erläutert ist.Further details and advantages can be found in the information below in the context of an exemplary embodiment which is explained with reference to a figure.
In der Figur ist innerhalb der Kassette 1 die Achse 6 fliegend gelagert. Auf ihr ist ein Schneckenrad 15 gelagert, mit der eine Schnecke 16 in Eingriff steht. Die Schnecke sitzt auf einer Schneckenwelle 18, die innerhalb der Kassette 1 um eine Pendellager 19 schwenkbar gelagert ist. Das bewegliche Ende der Welle 18 ist durch ein in einer gestellfesten Kulisse 20 verschiebbares Lager 21 so geführt, daß sie zwar parallel zur Kassettenhinterwand bewegt werden kann, jedoch nicht senkrecht dazu. Wird Schnecke 16 mit Schneckenrad 15 in Zahneingriff gebracht, so wird das verschiebbare Lager 21 durch die angefederte Klinke 21a gegen aushebend wirkende Zahnkräfte gesperrt.In the figure, the axis 6 is cantilevered within the cassette 1. On her a worm wheel 15 is mounted, with one Screw 16 is engaged. The snail sits on a worm shaft 18, which is mounted within the cassette 1 so as to be pivotable about a self-aligning bearing 19. The movable end of the shaft 18 is through an in a frame-fixed link 20 displaceable bearing 21 guided so that it can be moved parallel to the cassette rear wall, but not perpendicular to it. If the worm 16 is brought into meshing engagement with the worm wheel 15, the displaceable bearing 21 is The spring-loaded pawl 21a is blocked against tooth forces acting as an excavation.
Die Welle 18 trägt an ihrem von der Schnecke 16 entfernten Ende das eine Teil 22 einer Klauenkupplung, deren Gegenstück 23 auf der Welle eines Motors 24 innerhalb eines Kopiergerätes 25 angebracht ist. DasThe shaft 18 carries the at its end remote from the screw 16 a part 22 of a claw coupling, the counterpart 23 of which is mounted on the shaft of a motor 24 within a copier 25. That

PG 6191ZMG 8881 PG 619 1 ZMG 888 1
Teil 23 der Klauenkupplung ist etwa eben mit der Seitenwand des" Kopiergerätes 25, aus der ferner ein Haken 25a und ein Stift 25b vorragen, welche mit entsprechenden Haltemitteln la und einer Bohrung Ib der Kassette im eingehängten Zustand zusammenwirken.Part 23 of the claw coupling is roughly level with the side wall of the " Copier 25, from which a hook 25a and a pin 25b also protrude, which with corresponding holding means la and a Borehole Ib of the cassette cooperate in the suspended state.
/Steigungswinkel der Schnecke 16 beträgt höchstens 10 °, so daß diese gegenüber dem Schneckenrad 15 selbsthemmend ist./ The helix angle of the screw 16 is at most 10 °, so that this is self-locking with respect to the worm wheel 15.
Die Wirkungsweise der beschriebenen Kassette ist nun so:The mode of operation of the described cassette is now as follows:
Zum Einstellen der Welle 6 für den Wickelkern kann die Schnecke 16 von Hand abgehoben werden., nachdem die Klinke 21a entriegelt ist, bis der Wickelkern in der zur Aufnahme des Bandanfangs richtigen Stellung steht. Dann läßt man die Schnecke einfallen und eine zuverlässige Antriebsverbindung zwischen dem Motor 24 und der Achse 6 ist hergestellt. Diese Konstruktion erlaubt es, bei im wesentlichen glatter Seitenwand des Kopiergerätes eine Kassette nur in dem Haken 25a einzuhängen und den Stift 25b in die Bohrung Ib einzuführen, um eine hinreichend genaue Befestigung der Kassette an der Gerätewand durchzuführen. Gleichzeitig wird durch die Klauenkupplung 22, 23 die Antriebsverbindung mit der Welle 6 hergestellt.To adjust the shaft 6 for the winding core, the worm 16 be lifted by hand. After the pawl 21a is unlocked, until the winding core is in the correct for receiving the beginning of the tape Position. Then the worm is collapsed and a reliable drive connection between the motor 24 and the axis is made 6 is made. This construction allows a cassette only in a substantially smooth side wall of the copier hang the hook 25a and insert the pin 25b into the hole Ib, in order to carry out a sufficiently precise fastening of the cassette to the device wall. At the same time, the dog clutch 22, 23 established the drive connection with the shaft 6.
Nach der Abnahme der Kassette von dem Gerät, die jetzt mit einer größeren Menge belichteten, aufgerollten Materials gefüllt ist, ist das Schneckenrad 15 durch die selbsthemmende Schnecke 16 blockiert, d. h. durch äußere Beschleunigung auf die Kassette kann die Rolle auf dem Wickelkern sich nicht gegenüber dem Kassettengehäuse verdrehen , so daß das unter Umständen sehr kurz aus der Kassette vorstehende Bandende nicht in diese hineingezogen werden kann.After removing the cassette from the device, it is now filled with a larger amount of exposed, rolled-up material the worm wheel 15 blocked by the self-locking worm 16, d. H. due to external acceleration on the cassette, the roll on the winding core cannot rotate in relation to the cassette housing so that the projecting out of the cassette may be very brief The end of the tape cannot be drawn into this.

Anstelle der Lagerung für die Welle 18 in dem Pendellager 19 kann an dieser Stelle ein starres Lager vorgesehen und die Welle 18 mit einem Gelenk versehen sein. Eine Kulissenführung für den beweglichen Teil der Welle entsprechend den Teilen 20, 21 ist dann ebenfalls erforderlich.Instead of the storage for the shaft 18 in the self-aligning bearing 19 can a rigid bearing can be provided at this point and the shaft 18 can be provided with a joint. A link guide for the movable part of the shaft corresponding to the parts 20, 21 is then also required.
