Description

Die Erfindung betrifft eine kombinierte Vorrichtung zur Entnahme von Filmen aus Kassetten und zur Verarbeitung der entnommenen Filme, in welcher ein lichtdicht verschliessbarer Behälter Mittel zum Halten einer Filmkassette in solcher Weise enthält, dass aus der Kassette ein Filmstreifen bestimmter Länge herausgezogen werden kann, und die eine Filmabschneideeinrichtung umfasst.The invention relates to a combined device for removing films from cassettes and for processing the removed films, in which a light-tight sealable container contains means for holding a film cassette in such a way that a film strip of a certain length can be pulled out of the cassette, and one Film cutter includes.

In den letzten Jahren ist es in wachsendem Masse üblich geworden, daheim photographische Filme zu entwickeln und von ihnen Abzüge zu machen. Gleichzeitig wird es aber auch immer schwieriger für diejenigen, die es vorhaben, einen geeigneten Raum zu Hause zu finden, der hinreichend abgedunkelt werden kann, um als Dunkelkammer Verwendung zu finden. Denn insbesondere wenn ein normaler, mit einer Filmwickelspirale ausgestatteter Verarbeitungstank mit einem direkt aus einer Kassette entnommenen belichteten Film beschickt werden soll, so muss dieser Vorgang in einem völlig gegen sichtbares Licht abgedunkelten Raum durchgeführt werden.In recent years it has become increasingly common to develop photographic films at home and to make prints from them. At the same time, however, it is becoming increasingly difficult for those who plan to find a suitable room at home that can be darkened sufficiently to be used as a darkroom. This is because, especially if a normal processing tank equipped with a film winding spiral is to be loaded with an exposed film taken directly from a cassette, this process must be carried out in a room completely darkened from visible light.

Es sind bereits eine ganze Anzahl von Verfahren zum Beschicken von Verarbeitungstanks bei Tageslicht in der Patentliteratur beschrieben aber nur wenige davon infolge ihrer Herstellungskosten und umständlichen und sehr viel Raum beanspruchenden Bauweise in der Praxis verwendet worden. So wird z.B. in der US-A Nr. 2290152 ein komplexer, bei Tageslicht (d.h. ohne Erfordernis einer Dunkelkammer) zu beschickender Entwicklungstank beschrieben, bei welchem die zu entladende Filmkassette in eine Hilfskammer eingebracht wird. Der Tank dieser Vorrichtung ist sehr sperrig und ist nur schwierig mit dem Film zu beschicken.A large number of methods for loading processing tanks in daylight have already been described in the patent literature, but only a few of them have been used in practice because of their production costs and cumbersome and very space-consuming construction. For example, US-A No. 2290152 describes a complex development tank to be loaded in daylight (i.e. without the need for a dark room), in which the film cassette to be unloaded is placed in an auxiliary chamber. The tank of this device is very bulky and is difficult to load with the film.

Eine ähnlich komplizierte und sperrige Vorrichtung ist in der G B-A Nr. 671 170 beschrieben. Eine elegantere Lösung des Problems bietet die in der US-A Nr. 3906966 beschriebene Anordnung, bei welcher der Film aus einer Kassette beim Entladen auf eine Filmwickelspirale gebracht wird, welche sich in einerflachen Behandlungsschale und nicht in einem Tank befindet. In einer solchen flachen Schale wäre jedoch die Behandlung des Films keine einheitlich gleichmässige, da der Film nur sehr schwierig gleichmässig zu befeuchten und die richtige Art der Flüssigkeitsbewegung in der Schale schwer zu erzeugen wäre. Eine noch kompliziertere Lösung des Problems wird in der FR-A Nr. 2369597 beschrieben, in welcher ein Film bei Tageslicht auf eine aus einem Aufnahmeelement ausgefahrene längliche Spindel aufgebracht wird, die anschliessend in das Aufnahmeelement zurückgezogen wird. Um den Film zu behandeln, wird das Element an einen Behandlungsbehälter angeschlossen, worauf die Spindel aus dem Element in den Behälter hinein gefahren wird. Der Film wird dann von der Spindel in die Flüssigkeit hinein abgerollt und im Anschluss an die Behandlung wieder aufgewickelt.A similarly complicated and bulky device is described in G B-A No. 671 170. A more elegant solution to the problem is provided by the arrangement described in US-A No. 3906966, in which the film is transferred from a cassette to a film winding spiral when unloaded, which is located in a flat treatment tray and not in a tank. In such a flat dish, however, the treatment of the film would not be uniformly uniform, since the film would be very difficult to moisten evenly and it would be difficult to produce the correct type of liquid movement in the dish. An even more complicated solution to the problem is described in FR-A No. 2369597, in which a film is applied in daylight to an elongated spindle extended from a receiving element, which is then retracted into the receiving element. In order to treat the film, the element is connected to a treatment container, whereupon the spindle is moved out of the element into the container. The film is then rolled off the spindle into the liquid and wound up again after the treatment.

Es ist nun die Aufgabe der Erfindung, eine Vorrichtung der eingangs beschriebenen Art zu verwirklichen, welche gestattet, einen normalen mit einer Filmwickelspirale ausgestatteten Tageslichtbehandlungstank auch bei Tageslicht, also ohne Arbeiten in einer Dunkelkammer, mit belichtetem Film zu beschicken.It is now the object of the invention to implement a device of the type described in the introduction, which allows a normal daylight treatment tank equipped with a film winding spiral to be loaded with exposed film even in daylight, that is to say without working in a dark room.

Dies wird gemäss der Erfindung durch eine eingangs beschriebene Vorrichtung erreicht, die die im Anspruch 1 aufgeführten kennzeichnenden Merkmale aufweist.This is achieved according to the invention by a device described in the introduction, which has the characteristic features listed in claim 1.

Bevorzugte Merkmale der Erfindung sind in den Unteransprüchen beschrieben. Durch ein Drehverschlusselement kann das Gehäuseteil unter Drehung zum Deckel hin bewegt werden, nachdem der Film auf die Spirale aufgewickelt ist.Preferred features of the invention are described in the subclaims. By means of a twist lock element, the housing part can be moved towards the cover after rotation, after the film has been wound onto the spiral.

Bei Verwendung eines Beutels, in welchem das in Anspruch 1 erwähnte Tankgefäss (im wesentlichen bestehend aus dem Boden und der Seitenwandung des Tanks) untergebracht ist, kann das Anfügen des letzteren an den Deckel durch entsprechende Manipulation des Beutels von aussen her erfolgen.When using a bag in which the tank vessel mentioned in claim 1 (essentially consisting of the bottom and the side wall of the tank) is accommodated, the latter can be attached to the lid by appropriate manipulation of the bag from the outside.

Die Filmwickelspirale kann vom Innenwickeltyp oder vom Aussenwickeltyp sein, wobei aber im letzteren Falle ein Stirnradmechanismus vorhanden sein muss, mittels welchem der Film durch oszillierende Bewegung aufgewickelt wird. Der Verarbeitungstank ist vorzugsweise vom von oben füllbaren Typ, wobei Flüssigkeit durch Kippen des Tanks aus diesem entfernt wird. Jedoch kann der Tank auch vom Bodenfülltyp sein, bei welchem im Deckel und im Boden des Tanks lichtdichte, jedoch einen Durchtritt von Flüssigkeit gestattende Öffnungen vorgesehen sind, so dass beim Einbringen des Tanks in eine Flüssigkeit diese durch die Öffnungen im Tankboden in den Tank einströmt. Wird der Tank aus dem Bad herausgehoben, so strömt die Badflüssigkeit durch diese Bodenöffnungen wieder aus dem Tank.The film winding spiral can be of the inner winding type or of the outer winding type, but in the latter case there must be a spur gear mechanism by means of which the film is wound up by an oscillating movement. The processing tank is preferably of the top fill type, with liquid being removed from it by tilting the tank. However, the tank can also be of the bottom fill type, in which light-tight openings are provided in the lid and in the bottom of the tank, but allow liquid to pass through, so that when the tank is introduced into a liquid, it flows into the tank through the openings in the tank bottom. If the tank is lifted out of the bath, the bath liquid flows out of the tank through these floor openings.

In allen Figuren haben gleiche Bezugsziffern die gleiche Bedeutung.In all figures, the same reference numbers have the same meaning.

Wie in Fig. 1 gezeigt, umfasst ein lichtdicht abgeschlossenes Gehäuse 1 eine Halteeinrichtung 2, in welche eine Kassette 3 eingerastet ist. Ein Stück des Films 4 ist bereits aus der Kassette 3 herausgezogen und bereit zum Aufwickeln auf eine Filmwickelspirale 5 eines als wesentliche Teile einen Deckel 6, eine Seitenwandung und einen geschlossenen Boden umfassenden Verarbeitungstanks. Diese Spirale 5 ist am Deckel 6 des Verarbeitungstanks angebracht und umfasst eine mittige Welle 7 und zwei auf der Welle 7 sitzende Scheiben 10, von denen jede eine Spirale 9 trägt.As shown in FIG. 1, a housing 1, which is closed in a light-tight manner, comprises a holding device 2, into which a cassette 3 is locked. A piece of the film 4 has already been pulled out of the cassette 3 and is ready for winding onto a film winding spiral 5 of a processing tank comprising essential parts, a cover 6, a side wall and a closed bottom. This spiral 5 is attached to the cover 6 of the processing tank and comprises a central shaft 7 and two disks 10 seated on the shaft 7, each of which carries a spiral 9.

Der Filmstreifen 4 wird weiter an einer vorzugsweise guillotineartigen Abschneidvorrichtung 11 vorbeigeführt. Eine Deckelkappe 8 überdeckt den Deckel 6 von aussen.The filmstrip 4 will continue to be preferred wise guillotine-like cutting device 11 passed. A lid cap 8 covers the lid 6 from the outside.

In der dem Deckel 6 gegenüber gelegenen Wandung des Behälters 1 ist ein den geschlossenen Boden 12a und die vorzugsweise zylindrische Seitenwandung des Tanks umfassendes Tankergänzungsteil 12 mit seinem offenen Ende 12b lichtdicht angeschlossen.In the wall of the container 1 opposite the cover 6, a tank supplementary part 12 comprising the closed bottom 12a and the preferably cylindrical side wall of the tank is connected with its open end 12b in a light-tight manner.

Fig. 2 zeigt die Anordnung des Tankergänzungsteils 12 in der einen Seitenwand des Behälters 1 in bezug auf die Spirale 5 und den Deckel 6 vor dem Aufwickeln eines belichteten Filmstreifens auf die Spirale 5. Das Gehäuse 1 der Vorrichtung ist hier durch einen Gehäuseoberteil 13 geschlossen, und das Tankergänzungsteil 12 ist durch eine umlaufende Doppeldichtung 14 in der dem Deckel 6 gegenüberliegenden Wand des Gehäuses 1 lichtdicht und gleichwohl drehbar bzw. axial verschiebbar gelagert. Am Umfang des Dekkels 6 ist eine Ringnut 15 vorgesehen, in welche eine in der Wandung 16 des Gehäuses 1 und im Oberteil 13 ausgesparte Öffnung umgebende Randteile lichtdicht eingreifen. Die Öffnungsränder der Gehäusewandung 16 und des Gehäuseoberteils 13 bilden zusammen mit der Ringnut 15 eine drehbare, aber völlig lichtundurchlässige Abdichtung. Der sich achsparallel um den Deckel 6 herum erstreckende Randflansch 17 passt auf einen entsprechend abgesetzten Rand um die Öffnung 12b des Tankergänzungsteils 12.2 shows the arrangement of the tank supplementary part 12 in the one side wall of the container 1 with respect to the spiral 5 and the cover 6 before an exposed film strip is wound onto the spiral 5. The housing 1 of the device is closed here by a housing upper part 13, and the tank supplementary part 12 is mounted in a light-tight and nonetheless rotatable or axially displaceable manner by means of a circumferential double seal 14 in the wall of the housing 1 opposite the cover 6. On the circumference of the cover 6, an annular groove 15 is provided, into which an edge part surrounding the opening 16 in the wall 16 of the housing 1 and in the upper part 13 engages in a light-tight manner. The opening edges of the housing wall 16 and the upper housing part 13 together with the annular groove 15 form a rotatable, but completely opaque seal. The edge flange 17, which extends axially parallel around the cover 6, fits on a correspondingly stepped edge around the opening 12b of the tank supplement part 12.

Die Filmwickelspirale 5 besitzt eine Welle 7, auf welcher sich Hakenvorsprünge 18 zum Festhalten des vorlaufenden Endes des Films 4 befinden.The film winding spiral 5 has a shaft 7, on which there are hook projections 18 for holding the leading end of the film 4.

Der durch lichtdichtes Verschieben des Tankergänzungsteils 12 nach links bis zum Eingriff des Randes der Öffnung 12b mit Festsitz unter dem Ringflansch 17 des Deckels 6 vervollständigte und lichtdicht verschlossene Tank ist in Fig. 3 gezeigt.The tank, which is completed by light-tight displacement of the tank supplement part 12 to the left up to the engagement of the edge of the opening 12 b with a tight fit under the ring flange 17 of the cover 6, is shown in FIG. 3.

Das Tankergänzungsteil kann vorzugsweise aus nichtrostendem Stahl und der Deckel 6 und die Deckelkappe 8 können aus mehr oder weniger elastischem Kunststoff hergestellt werden. Die Deckelkappe 8 verschliesst einen Flüssigkeitsdurchlass 19 im Deckel 6, durch welchen hindurch nach dem Entfernen der Deckelkappe 8 sowie durch Fenster 20 in einem Deckelinnenringflansch 21 Entwickler und andere Behandlungsflüssigkeiten in den vervollständigten und mit dem Deckel 6 nach oben gestellten Tank eingefüllt werden können, ohne dass Licht in das Tankinnere fallen kann, da eine auf der Spiralenwelle 7 an deren dem Deckel 6 zugewandten Ende fest aufsitzende Lichtdichtungsscheibe 22 dies durch feste Verbindung mit dem Rand des Innenringflansches 21 von bedeutend kleinerem Durchmesser als demjenigen der Scheibe 22 verhindert.The tank supplementary part can preferably be made of stainless steel and the cover 6 and the cover cap 8 can be made of more or less elastic plastic. The lid cap 8 closes a liquid passage 19 in the lid 6, through which, after removal of the lid cap 8 and through windows 20 in a lid inner ring flange 21, developer and other treatment liquids can be filled into the tank which has been completed and with the lid 6 placed upwards, without this Light can fall into the interior of the tank, since a light sealing washer 22, which sits firmly on the spiral shaft 7 at its end facing the cover 6, prevents this by firmly connecting to the edge of the inner ring flange 21 of a significantly smaller diameter than that of the washer 22.

Die in Fig. 1 und 2 gezeigte Filmwickelspirale 6 ist eine solche des Innenwindungstyps. Daher wird hierbei das freie Ende des Films 4 zur Mitte der Spirale 5 geführt und dort an den Hakenvorsprüngen 18 der Spiralwelle 7 fixiert.The film winding coil 6 shown in Figs. 1 and 2 is of the inner winding type. Therefore, the free end of the film 4 is guided to the center of the spiral 5 and fixed there on the hook projections 18 of the spiral shaft 7.

Zu Beginn der Inbetriebnahme der erfindungsgemässen Vorrichtung befinden sich der Dekkel 16 und das Tankergänzungsteil 12 in ihren in den Fig. 1 und 2 gezeigten Stellungen. Nun wird das Gehäuseoberteil 13 (Fig. 2) abgenommen und eine den belichteten Film 4 enthaltende Kassette 3 in ihren Halter 2 eingeschoben, worauf das vorauslaufende Ende des Films 4 durch einen Spalt in der Guillotine 11 hindurchgezogen und auf den Hakengliedern 18 der Spiralenwelle 7 befestigt wird. Das Behältergehäuse 1 wird dann wieder durch Aufsetzen des Gehäuseoberteils 13 geschlossen und der Film 4 auf die Spirale 5 durch Drehen der Deckelkappe 8 von aussen her unter Mitnahme von Deckel 6, Welle 7 und Scheiben 10 aufgewickelt. Sobald der Widerstand des Films 4 gegen weiteres Drehen anzeigt, dass der grösste Teil des Films 4 auf die Spirale 5 aufgewickelt ist, wird die Guillotine 11 betätigt, der Film 4 dicht am Kassettenausgang abgeschnitten und der Film fertig bis zum abgeschnittenen Ende auf die Spirale 5 aufgewickelt.At the start of the commissioning of the device according to the invention, the cover 16 and the tank supplement 12 are in their positions shown in FIGS. 1 and 2. Now the upper housing part 13 (FIG. 2) is removed and a cassette 3 containing the exposed film 4 is inserted into its holder 2, whereupon the leading end of the film 4 is pulled through a gap in the guillotine 11 and fastened on the hook members 18 of the spiral shaft 7 becomes. The container housing 1 is then closed again by fitting the upper housing part 13 and the film 4 is wound onto the spiral 5 by rotating the cover cap 8 from the outside, taking the cover 6, shaft 7 and disks 10 with it. As soon as the resistance of the film 4 to further rotation indicates that most of the film 4 has been wound onto the spiral 5, the guillotine 11 is actuated, the film 4 is cut off close to the cassette exit and the film is finished on the spiral 5 until the cut end wound up.

Das Tankergänzungsteil 12 wird dann unter Drehen und/oder Schieben in das Innere des Gehäuses 1 hineingedrückt, bis sein Rand um die Öffnung 12b mit lichtdichtem Festsitz in den Ringflansch 17 hineingeschoben ist. Das Gehäuseoberteil kann dann abgehoben und der wie in Fig. 3 gezeigt verschlossene Tank aus dem Gehäuse 1 herausgenommen werden. Der im Tank befindliche Film kann dann in üblicher Weise behandelt werden.The tank add-on part 12 is then pressed into the interior of the housing 1 while rotating and / or pushing until its edge is pushed into the ring flange 17 with a light-tight interference fit around the opening 12b. The upper housing part can then be lifted off and the tank closed as shown in FIG. 3 can be removed from the housing 1. The film in the tank can then be treated in the usual way.
