Abstract

A wet-development apparatus for sheet films with darkroom-side introduction of the sheet films to be developed and a transport device for moving the sheet films slowly through the apparatus is designed in such a way that a sheet film stacking device (18, 19) is provided, with a loading flap (17), which can be opened from the outside, for introducing sheet film stacks (14) and a draw-off device (21) for individual sheet films on the stack side away from the loading flap (17), that an individual sheet contact surface (10) is located below or above the loading flap (17), that, after the draw-off device (21) and the individual sheet contact surface (10), sheet film transport means (9; 22) are mounted, by means of which a sheet film can be transferred from the individual sheet contact surface (10) or from the sheet film stacking device (18, 19) into the transport device (8) and that sheet film scanning means (14, 23) are located on the transport paths which are defined by the sheet film transport means (9, 22) and which, when the sheet film is present on the individual sheet contact surface (10), can switch off a drive for the draw-off device (21) and the stack-side sheet film transport means (22) and switch on a drive for the individual sheet contact surface (10). As a result, it is possible to introduce sheet film stacks for development but to develop a particularly urgent sheet film preferentially. <IMAGE>

Description

Die Erfindung betrifft ein Blattfilmnaßentwicklungsge­rät mit einer dunkelkammerseitigen Eingabe der zu ent­wickelnden Blattfilme und einer Transportvorrichtung zur Bewegung der Blattfilme durch das Gerät.The invention relates to a sheet film wet developing device with a dark chamber-side input of the sheet films to be developed and a transport device for moving the sheet films through the device.

Es ist bei derartigen Geräten bekannt, die zu ent­wickelnden Blattfilme einzeln von Hand einzugeben. Ge­nerell sind auch Blattfilmstapler bekannt, mit denen die einzelnen Filme nacheinander von einem Stapel auto­matisch abgezogen und in ein Gerät eingeführt werden. Würde man einen derartigen Blattfilmstapler zur Eingabe in ein eingangs genanntes Gerät verwenden, so hätte man keine Möglichkeit mehr, einen einzelnen, besonders eiligen Blattfilm sofort zu entwickeln.In such devices, it is known to enter the sheet films to be developed individually by hand. Sheet film stackers are also generally known, with which the individual films are automatically pulled from a stack one after the other and introduced into a device. If one were to use such a sheet film stacker for input into a device mentioned at the beginning, one would no longer be able to develop a single, particularly urgent sheet film immediately.

Der Erfindung liegt daher die Aufgabe zugrunde, einer­seits zu entwickelnde Blattfilme in einer Dunkelkammer von Hand stapelweise in ein eingangs genanntes Gerät eingeben und im Gerät automatisch einzeln der Entwick­lungsvorrichtung zuführen zu können und andererseits einen besonders eiligen Blattfilm zwischendurch bevor­zugt entwickeln zu können.The invention is therefore based on the object, on the one hand, to input sheet films to be developed in a darkroom by hand in batches into a device mentioned at the beginning and automatically feed them individually to the developing device in the device, and on the other hand to be able to develop a particularly urgent sheet film in between.

Diese Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des Hauptanspruchs. Weitere vorteilhafte Merk­male der Erfindung sind den Unteransprüchen entnehmbar.This object is achieved by the features of the main claim. Further advantageous features of the invention can be found in the subclaims.

In den Figuren 1 und 4 sind je ein Blattfilmentwick­lungsgerät 1 mit Behandlungstanks 2 bis 5 und einer an­schließenden Trocknungsvorrichtung 6 und mit bekannten und nicht gezeigten Blattfilmtransportmitteln sowie einer Auffangvorrichtung 7 für die fertigen Blattfilme gezeigt. Vor einem Eingabewalzenpaar 8 des Gerätes 1 sind eine Eingangstransportstrecke 9, die durch Walzen oder Transportbänder gebildet sein kann, und eine Ein­zelblattanlagefläche 10 mit einem hochklappbaren Deckel 11 angeordnet. Im Bereich der Eingangstransport­strecke 9, vorzugsweise unmittelbar davor, ist eine Ab­tastvorrichtung 12 vorgesehen, durch die ein in die Einzelblattanlagefläche 10 eingeschobener Blattfilm er­kannt wird. Sie kann beispielsweise als Infrarotlicht­schranke, aber auch auf jede andere bekannte Art ausge­bildet sein.1 and 4 each show a sheet film processor 1 with treatment tanks 2 to 5 and a subsequent drying device 6 and with known and not shown sheet film transport means and a collecting device 7 for the finished sheet films shown. In front of a pair of input rollers 8 of the device 1, an input transport path 9, which can be formed by rollers or conveyor belts, and a single sheet contact surface 10 with a flip-up cover 11 are arranged. In the area of the input transport path 9, preferably directly in front of it, a scanning device 12 is provided, by means of which a sheet film inserted into the single sheet contact surface 10 is recognized. It can be designed, for example, as an infrared light barrier, but also in any other known way.

Gemäß den Figuren 1 bis 3 ist unterhalb der Einzel­blattanlagefläche 10 ein Gehäuseteil 13 mit einer Blattfilmstapelvorrichtung untergebracht, von der je­weils ein einzelner Blattfilm 14 in eine Zwischentrans­portstrecke 15 gefördert und von dort in die Eingangs­transportstrecke 9 und über diese in das Entwicklungs­gerät 1 geleitet wird. Zweckmäßigerweise befindet sich zwischen der Stapelvorrichtung und der Zwischentrans­portstrecke 15 eine Zwischenwand 16 mit einem Durch­führschlitz für Blattfilme 14. Am Gehäuseteil 13 ist eine Beladeklappe 17 oder ein verschließbarer Deckel angelenkt, in deren geöffneter Stellung zu entwickelnde Blattfilmstapel oder auch einzelne Blattfilme 14 in die Stapelvorrichtung von Hand eingebbar sind.According to FIGS. 1 to 3, a housing part 13 with a sheet film stacking device is accommodated below the single sheet contact surface 10, from which in each case an individual sheet film 14 is conveyed into an intermediate transport path 15 and from there into the input transport path 9 and via this into the developing device 1. Advantageously, between the stacking device and the intermediate transport section 15 there is an intermediate wall 16 with a through slot for sheet films 14. A loading flap 17 or a closable lid is articulated on the housing part 13, sheet film stacks to be developed in their open position or individual sheet films 14 in the stacking device by hand can be entered.

Gegenüber der Beladeklappe 17 im Innern des Gehäusetei­les 13 ist eine Auflagefläche 18 für einen Blattfilm­stapel fest angeordnet. Sie ist von oben nach unten ge­genüber der Vertikalen schwach auf die Beladeklappe 17 zu geneigt. Unterhalb der Auflagefläche 18 ist, von ihr beabstandet, ein Fangkorb 19 derart angeordnet, daß zwischen beiden Teilen 18, 19 ein Spalt 20 besteht, hinter dem eine Abziehvorrichtung 21 für den jeweils untersten, an der Auflagefläche 18 aufliegenden Blatt­film 14 gelagert ist. Ein an der Auflagefläche 18 an­liegender Blattfilmstapel liegt also mit seinem unteren Ende in dem Fangkorb 19. Ist das Gerät 1 in Betrieb, so wird der unterste Blattfilm von der Abziehvorrichtung 21, die im Ausführungsbeispiel als Sauger ausgebildet ist, nach unten und hinten aus der Stapelvorrichtung herausgezogen und mit seiner Unterkante in Blattfilm­transportmittel 22, die vorzugsweise durch Transport­walzenpaare gebildet werden, eingegeben. Durch die Blattfilmtransportmittel 22 wird der Blattfilm dann in die Transportstrecke 15 weitergeleitet und von dieser in bereits beschriebener Weise in das Entwicklungsge­rät 1. Im Bereich des durch die Blattfilmtransportmit­tel 22 definierten Blattfilmtransportweges ist wenig­stens ein Blattfilmabtastmittel 23, vorzugsweise eine Infrarotlichtschranke, angeordnet, die das Vorhanden­sein eines Blattfilms in dem Transportweg an eine Steu­erschaltung 24 meldet. Auch die Abtastvorrichtung 12 ist mit dieser Steuerschaltung 24 verbunden.Compared to the loading flap 17 in the interior of the housing part 13, a support surface 18 for a sheet film stack is fixed. It is slightly inclined from top to bottom with respect to the vertical towards the loading flap 17. Below the bearing surface 18 is from her spaced apart, a collecting basket 19 is arranged such that there is a gap 20 between the two parts 18, 19, behind which a pulling device 21 is mounted for the lowest sheet film 14 lying on the contact surface 18. A sheet film stack lying against the support surface 18 thus lies with its lower end in the collecting basket 19. When the device 1 is in operation, the bottom sheet film is pulled down and back out of the stacking device by the pulling device 21, which is designed as a suction device in the exemplary embodiment pulled out and entered with its lower edge in sheet film transport means 22, which are preferably formed by pairs of transport rollers. The sheet film is then forwarded by the sheet film transport means 22 into the transport path 15 and from there into the developing device 1 in the manner already described. At least one sheet film scanning means 23, preferably an infrared light barrier, is arranged in the area of the sheet film transport path defined by the sheet film transport means 22 Reports sheet film in the transport path to a control circuit 24. The scanning device 12 is also connected to this control circuit 24.

Auch an der Beladeklappe 17 ist ein Fangkorb 25 ange­ordnet. Er besteht aus einer im Querschnitt L-förmigen Platine, die an der Beladeklappe 17 über ein Träger­teil 25a derart angelenkt ist, daß seine Stützflä­che 25b für einzugebende Blattfilme in entgegengesetz­ter Richtung zu der Neigung der Auflagefläche 18 ge­neigt ist, wenn die Beladeklappe 17 geöffnet wird. In der geschlossenen Stellung der Beladeklappe 17 ist die Stützfläche 25b auf die Auflagefläche 18 zu geneigt, so daß auf der Stützfläche 25b liegende Blattfilme auf die Auflagefläche 18 bzw. einen hierauf bereits liegenden Blattfilmstapel fallen. In dieser geschlossenen Stel­lung der Beladeklappe 17 liegt das untere Ende des Fangkorbes 25 derart über und vor dem festen Fang­korb 19, daß die Unterkanten der im Fangkorb 25 befind­lichen Blattfilme in den festen Fangkorb 19 hinabglei­ten und daher die im Fangkorb 25 befindlichen Blattfil­me in der Stapelvorrichtung 18, 19 so abgelegt werden, daß sie nach Abtransport der bereits vorher gestapelten Blattfilme ebenfalls durch die Abziehvorrichtung 21 nacheinander in das Gerät 1 transportierbar sind.A collecting basket 25 is also arranged on the loading flap 17. It consists of a cross-sectionally L-shaped plate which is articulated on the loading flap 17 via a carrier part 25a in such a way that its support surface 25b for sheet films to be inserted is inclined in the opposite direction to the inclination of the bearing surface 18 when the loading flap 17 is opened. In the closed position of the loading flap 17 Support surface 25b inclined towards the support surface 18, so that sheet films lying on the support surface 25b fall onto the support surface 18 or a sheet film stack already lying thereon. In this closed position of the loading flap 17, the lower end of the collecting basket 25 lies above and in front of the fixed collecting basket 19 such that the lower edges of the sheet films located in the collecting basket 25 slide down into the fixed collecting basket 19 and therefore the leaf films located in the collecting basket 25 in the stacking device 18 , 19 are stored in such a way that after removal of the previously stacked sheet films, they can also be transported one after the other into the device 1 by the pulling device 21.

Die Beladeklappe 17 weist Seitenwände 17a auf. An ihnen sind Leitbleche 17b, 17c befestigt, die einen Einführ­kanal 17d für einzelne oder mehrere einzugebende Blatt­filme oder Blattfilmstapelteile bilden. Sie sind so ge­formt, daß in der geöffneten Stellung der Beladeklappe 17 die einzugebenden Blattfilme direkt auf die Stütz­fläche 25b und in den klappenseitigen Fangkorb 25 glei­ten. Zur Steuerung der Bewegung sowohl der Beladeklappe 17 als auch des klappenseitigen Fangkorbes 25 können in wenigstens einer der Seitenwände 17a zwei Schlitzkurven 17e und 17f vorgesehen sein. Außerdem kann, diesen zu­geordnet, in einer gehäuseteilseitigen Seitenwand eine weitere Schlitzkurve 13a (vgl. Figur 2) angeordnet sein. Die Steuerung der Bewegung des Fangkorbes 25 er­folgt über einen in die Schlitzkurve 17e eingreifenden, am Trägerteil 25a angeordneten Stift 26 und einen wei­teren am Trägerteil 25a angeordneten, in die Schlitz­kurve 13a eingreifenden Stift 27.The loading flap 17 has side walls 17a. Baffles 17b, 17c are attached to them and form an insertion channel 17d for one or more sheet films or sheet film stack parts to be entered. They are shaped so that in the open position of the loading flap 17 the sheet films to be inserted slide directly onto the support surface 25b and into the flap-side collecting basket 25. In order to control the movement of both the loading flap 17 and the flap-side collecting basket 25, two slit curves 17e and 17f can be provided in at least one of the side walls 17a. In addition, a further slot curve 13a (cf. FIG. 2) can be arranged in a side wall on the housing part side. The movement of the collecting basket 25 is controlled via a pin 26 which engages in the slot curve 17e and is arranged on the carrier part 25a and a further pin 27 which is arranged in the slot part 25a and engages in the slot curve 13a.

Für die Steuerung einer Dreh-Kipp-Bewegung der Belade­klappe 17 ist ein Gelenkdreieck mit den Lenkern 28, 29 vorgesehen. In dem Lenker 29 ist ein Stift 30 angeord­net, der in die Schlitzkurve 17f eingreift. Am unteren Ende des Lenkers 28 ist ebenfalls der Stift 27 angeord­net, so daß Lenker 28 und Fangkorb 25 gemeinsam in der Schlitzkurve 13a geführt werden. Das freie Ende des Lenkers 29 ist im Gehäuseteil 13 drehbar bei 31 gela­gert. Je nach der Form bzw. Länge des Bewegungsweges der Beladeklappe 17 kann es notwendig sein, den Lenker 29 teleskopisch ausziehbar auszubilden. Dabei kann das ausziehbare und zusammenschiebbare Lenkerteil 29a über eine Feder 32 mit dem bei 31 angelenkten Lenkerteil 29 gekoppelt sein. Es kann aber auch jede andere geeignete Steuermechanik für die Beladeklappe 17 und den klappen­seitigen Fangkorb 25 verwendet werden.An articulated triangle with the links 28, 29 is provided for controlling a rotation and tilting movement of the loading flap 17. A pin 30 is arranged in the link 29, which engages in the slot curve 17f. At the lower end of the handlebar 28, the pin 27 is also arranged so that the handlebar 28 and the catcher 25 are guided together in the slot curve 13a. The free end of the handlebar 29 is rotatably mounted in the housing part 13 at 31. Depending on the shape or length of the path of movement of the loading flap 17, it may be necessary to make the handlebar 29 telescopic. The extendable and collapsible link part 29a can be coupled via a spring 32 to the link part 29 articulated at 31. However, any other suitable control mechanism for the loading flap 17 and the flap-side collecting basket 25 can also be used.

Bei dem Ausführungsbeispiel nach Figur 4 ist die Sta­pelvorrichtung 18, 19 mit Beladeklappe 17 oberhalb der Einzelblattanlagefläche 10 angeordnet. Hierdurch wird die Blattfilmtransportstrecke 9, 22 kürzer. Dafür wird aber das gesamte Gerät raumgreifender. Im übrigen wer­den hier für funktionsgleiche Teile dieselben Bezugs­ziffern verwendet wie nach den Figuren 1 bis 3. Die Funktionsweise ist im wesentlichen dieselbe.In the exemplary embodiment according to FIG. 4, the stacking device 18, 19 with the loading flap 17 is arranged above the single sheet contact surface 10. As a result, the sheet film transport path 9, 22 is shorter. But the entire device is more space-consuming. For the rest, the same reference numerals are used here for functionally identical parts as in FIGS. 1 to 3. The mode of operation is essentially the same.

Kurz zusammengefaßt, ist diese Funktionsweise der ge­zeigten Vorrichtung die folgende.Briefly summarized, this operation of the device shown is the following.

Zum Eingeben von Blattfilmen oder Blattfilmstapeltei­len, die automatisch vom Stapel abgezogen und in das Gerät 1 eingegeben werden sollen, werden die Belade­ klappe 17 geöffnet und die Blattfilme in den Einführ­kanal 17d eingeschoben. Von hier fallen sie in den klappenseitigen Fangkorb 25 und werden beim Schließen der Beladeklappe 17 in die Stapelvorrichtung 18, 19 eingeschichtet. Dann werden durch den Spalt 20 die Blattfilme von unten nacheinander abgezogen und in das Entwicklungsgerät 1 transportiert. Die Lichtschranke 23 meldet das Vorhandensein von Blattfilm im Wege der Transportmittel 22. Wird nun ein besonders eiliger Blattfilm auf der Einzelblattanlagefläche 10 bis zur Lichtschranke 12 geschoben, so meldet letztere an die Steuervorrichtung 24, daß hier ein Transport erfolgen soll. Mittels der Steuervorrichtung wird die Abzieh­vorrichtung 21 stillgesetzt, so daß zunächst kein wei­terer Blattfilm vom Stapel abgezogen wird. Nach Frei­werden der durch die Transportmittel 22 und 15 defi­nierten Blattfilmtransportstrecken wird die Transport­strecke 9 eingeschaltet und der hier eingegebene ein­zelne Blattfilm bevorzugt in das Entwicklungsgerät 1 eingeführt. Ist dieser in das Gerät 1 eingeführt und folgt kein weiterer Einzelfilm an der Lichtschranke 12, so wird über die Steuervorrichtung 24 die Abziehvor­richtung 21 wieder in Betrieb gesetzt, so daß der Blattfilmtransport vom Stapel fortgesetzt wird. Sinn­voll kann es dabei sein, daß ein Hauptschalter 33 vor­gesehen ist, durch den erst in der geschlossenen Stel­lung der Beladeklappe 17 der Antrieb für die Abzieh­mittel 21 und die stapelseitigen Blatttransportmittel 22 einschaltbar ist.The loading is carried out for entering sheet films or sheet film stack parts which are to be automatically pulled off the stack and entered into the device 1 flap 17 opened and the sheet films inserted into the insertion channel 17d. From here they fall into the flap-side collecting basket 25 and are stacked into the stacking device 18, 19 when the loading flap 17 is closed. Then, through the gap 20, the sheet films are drawn off one by one from below and transported into the developing device 1. The light barrier 23 reports the presence of sheet film by means of the transport means 22. If a particularly urgent sheet film is now pushed on the single sheet contact surface 10 up to the light barrier 12, the latter reports to the control device 24 that a transport is to take place here. The pulling device 21 is stopped by means of the control device, so that no further sheet film is first pulled off the stack. After the sheet film transport routes defined by the transport means 22 and 15 have become free, the transport route 9 is switched on and the individual sheet film entered here is preferably introduced into the developing device 1. If this is inserted into the device 1 and there is no further individual film on the light barrier 12, the pulling device 21 is put into operation again via the control device 24, so that the sheet film transport from the stack is continued. It can make sense that a main switch 33 is provided, by means of which the drive for the pulling means 21 and the stack-side sheet transport means 22 can only be switched on in the closed position of the loading flap 17.
