Description

Die Erfindung betrifft ein Vorratsmagazin zum Einsetzen in eine Vorrichtung zum Entnehmen einzelner Blattfilme, vorzugsweise Röntgenblattfilme, in das Blattfilme als Stapel in einer lichtdichten, vorzugsweise an einer Aufreißlasche bei geschlossenem Vorratsmagazin an einer Seite zu öffnenden Umhüllung einlegbar sind, wobei das Vorratsmagazin aus einer oben zumindest teilweise offenen, durch einen Deckel verschließbaren Box für den in der Umhüllung befindlichen Stapel besteht und wobei an der der Aufreißlasche gegenüberliegenden Seite der Box eine Aufwickelvorrichtung mit einer von außen antreibbaren Aufwickelwelle zum Einhängen und Aufwickeln einer Aufwickellasche der Umhüllung samt dieser nach dem Verschließen des Vorratsmagazins angeordnet ist.The invention relates to a storage magazine for insertion into a device for removing individual sheet films, preferably X-ray sheet films, into which sheet films can be inserted as a stack in a light-tight, preferably on a tear-open tab with the storage magazine closed on one side, the storage magazine consisting of at least one top there is a partially open box, which can be closed by a lid, for the stack located in the wrapper and, on the side of the box opposite the tear-open flap, a winding device with an externally drivable winding shaft for hanging and winding a wrapping flap of the wrapper together with this after the storage magazine has been closed is.

Vorratsmagazine ähnlicher Art sind beispielsweise bekannt durch die DE-GMS 77 25 804 oder die DE-PS 34 05 423. Bei derartigen bekannten Magazinen ist es nicht möglich, nach deren Verschließen zu erkennen, ob die Umhüllung tatsächlich so weit vom Stapel entfernt ist, daß die einzelnen Filmblätter vom Stapel abgenommen werden können.Storage magazines of a similar type are known, for example, from DE-GMS 77 25 804 or DE-PS 34 05 423. In the case of such known magazines, it is not possible to recognize after their closure whether the wrapper is actually so far from the stack that the individual film sheets can be removed from the stack.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Vorratsmagazin der eingangs genannten Art so auszubilden, daß erkennbar ist, ob die Umhüllung auf die Aufwickelwelle bei deren Drehung aufgewickelt wird.The invention is therefore based on the object of designing a storage magazine of the type mentioned at the outset in such a way that it can be seen whether the covering is wound onto the winding shaft when it rotates.

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

Es sind Vorrichtungen zum Ent- und Beladen von Röntgenblattfilmkassetten bekannt, die Schubladen zum Einsetzen von Vorratsmagazinen 2 für Blattfilmstapel verschiedener Formate aufweisen. Die Blattfilmstapel wurden dabei bisher in einer Dunkelkammer ihren lichtdichten Umhüllungen entnommen, in ein Vorratsmagazin 2 eingelegt und dann im geschlossenen Magazin in die entsprechende Schublade der Vorrichtung eingesetzt. Das Magazin wird dicht darin eingeschlossen und geöffnet, so daß bei Bedarf einem Filmstapel der benötigten Blattgröße ein Blatt von oben entnommen und in eine zuvor entleerte Kassette eingeführt werden kann. In einer bekannten derartigen Vorrichtung nach der DE-PS 31 22 583 wurden bereits Vorratsmagazine verwendet, die aus einer oben nur teilweise offenen Box 2a und einem als Schieberrohr 2b ausgebildeten Deckel gemäß der DE-PS 31 22 582 bestanden. Die Eingabeöffnung der Box 2a liegt dabei der in Eingaberichtung 3 des Magazins 2 in die Vorrichtung liegenden Stirnseite 2h der Box 2a benachbart. Die Eingabeöffnung ist nur so groß, daß ein Filmstapel in die Box 2a einsetzbar und darin positionierbar ist und daß sie im vorgeschobenen Zustand des Schieberrohrs 2b durch dieses lichtdicht verschließbar ist. Die in Eingaberichtung 3 rückwärtige Magazinstirnseite 2d ist bei den bekannten Magazinen 2 fest an der Box 2a angebracht und als Griffteil zum Einschieben des Magazins 2 in die Vorrichtung 1 und zum Entnehmen aus ihr ausgebildet.Devices for unloading and loading X-ray sheet film cassettes are known, which have drawers for inserting storage magazines 2 for sheet film stacks of different formats. The sheet film stacks have so far been removed from their light-tight envelopes in a darkroom, placed in a storage magazine 2 and then inserted into the corresponding drawer of the device in the closed magazine. The magazine is tightly enclosed and opened so that, if necessary, a sheet can be taken from above from a film stack of the required sheet size and inserted into a previously emptied cassette. In a known device of this type according to DE-PS 31 22 583, storage magazines have already been used which consist of a box 2a, which is only partially open at the top, and a cover according to DE-PS 31 22 582, which is designed as a slide tube 2b. The entry opening of the box 2a is adjacent to the end face 2h of the box 2a lying in the direction of entry 3 of the magazine 2 in the device. The input opening is only so large that a film stack can be inserted into and positioned in the box 2a and that it can be closed in a light-tight manner by the slide tube 2b in the advanced state. In the known magazines 2, the rear magazine end face 2d in the input direction 3 is firmly attached to the box 2a and is designed as a grip part for inserting the magazine 2 into the device 1 and for removing it therefrom.

Um nun ein Magazin 2 als Tageslichtmagazin, also zum Einlegen eines Filmstapels samt dessen lichtdichter Umhüllung 4 und zum Entfernen der Umhüllung 4 vom Filmstapel nach dem Schließen des Magazins 2 verwenden zu können, ist die rückwärtige Magazinstirnseite 2d als abklappbare, in ihrem angeklappten Zustand lichtdicht schließende Rückwand ausgebildet. Unmittelbar hinter ihr im Innern der Box 2a ist eine Aufwickelwelle 6 an den Seitenwänden der Box 2a bzw. der Rückwand 2d gelagert. Sie weist Klammern 7 auf, mit denen eine aufwickellasche 4a einer neu eingelegten Umhüllung 4 an der Aufwickelwelle 6 fest klemmbar ist. Die Aufwickelwelle 6 kann direkt oder über Zahnräder mit einer lichtdicht aus der Rückwand 2d nach außen geführten Aufwickelkurbel 10 gekuppelt sein. Letztere kann ein klappbares, nicht gezeigtes Gelenk aufweisen, so daß sie in die in Figur 1 gezeigte Funktionsstellung oder in eine in eine Vertiefung 2e der Rückwand 2d eingeschwenkte Nichtgebrauchslage schwenkbar ist. Letztere Nichtgebrauchslage soll sie beim Einsetzen des Magazins 2 in die Vorrichtungs 1 einnehmen. Das Magazin 2 nach den Figuren ist so ausgebildet, daß an der in Einschubrichtung 3 schauenden Stirnkante 2g des Schieberdeckels 2b oberhalb der Eingabeöffnung eine Abreißleiste angebracht ist.In order to be able to use a magazine 2 as a daylight magazine, i.e. for inserting a film stack including its light-tight wrapping 4 and for removing the wrapping 4 from the film stack after the magazine 2 has been closed, the rear magazine end face 2d is foldable and light-tight in its folded state Rear wall. Immediately behind it inside the box 2a, a winding shaft 6 is mounted on the side walls of the box 2a or the rear wall 2d. It has clips 7 with which a winding tab 4a of a newly inserted casing 4 can be firmly clamped to the winding shaft 6. The take-up shaft 6 can be coupled directly or via gearwheels with a take-up crank 10 which is led out of the rear wall 2d in a light-tight manner. The latter can have a foldable hinge, not shown, so that it can be pivoted into the functional position shown in FIG. 1 or into a non-use position pivoted into a recess 2e of the rear wall 2d. The latter should not occupy the position of use when inserting the magazine 2 into the device 1. The magazine 2 according to the figures is designed such that a tear-off bar is attached to the front edge 2g of the slide cover 2b looking in the direction of insertion 3 above the input opening.

Im folgenden wird nun die Funktionsweise des gezeigten Ausführungsbeispiels eines erfindungsgemäßen Vorratsmagazins 2 zum besseren Verständnis der Erfindung beschrieben. Zur Wiederbeladung eines leeren Magazins 2 werden sowohl die Eingabeöffnung durch Öffnen des Schieberdeckels 2b als auch die Aufwickelwelle 6 durch Öffnen der Rückwand 2d freigelegt. Dann werden von der Aufwickelwelle 6 die dort aufgewickelte Umhüllung 4 des bereits entnommenen Filmstapels abgezogen und aus der Box ein unter dem entleerten Stapel vorgesehener Versteifungs- und Haltekarton entnommen. Letzterer weist an der Rückseite einen hochstehenden Anschlag auf. Der Haltekarton (*) samt Anschlag dient dazu, beim Abziehen der Hülle 4 vom Stapel in einem geschlossenen Magazin 2 eine Verschiebung des Stapels oder einzelner seiner Blätter durch Mitnahme durch die Umhüllung zu verhindern. Dann wird ein neuer Filmstapel samt Umhüllung 4 durch die Eingabeöffnung in die Box 2a eingelegt, wobei die Aufwickellasche 4a bis in den Bereich derAufwickelwelle 6 geführt und an der Aufwickelwelle 6 mittels der Klammern 7 festgeklemmt wird. Der in Einschubrichtung 3 des Magazins 2a in die Vorrichtung 1 stirnseitige Verschlußlappen 4b der Umhüllung soll bei geschlossenem Magazin 2 auf einfache Weise abreißbar sein und wird deshalb als Aufreißlasche 4b bezeichnet. Diese Aufreißlasche 4b also wird bei geöffnetem Magazin 2 so gelegt, daß sie nach dem Schließen des Magazins zwischen der Abreißleiste und der Oberfläche der Boxstirnseite 2h aus dem Magazin vorschaut. Diese Stellung ist in den Figuren 1 und 2 gezeigt. Dann wird die Kurbel 10 ausgeschwenkt und auch die Rückwand 2d geschlossen, vgl. Figuren 1 und 2. Schließlich wird mittels und längs der Abreißleiste die Aufreißlasch 4b von Hand abgetrennt. Somit ist die Umhüllung 4 in dem geschlossenen Magazin 2 stirnseitig geöffnet, so daß sie nun auch ohne merklichen Kraftaufwand nach hinten abgezogen werden kann. Daher wird nun die Kurbel 10 bewegt, wodurch die Welle 6 gedreht wird. Dabei werden Aufwickellasche 4a und Umhüllung 4 vorzugsweise völlig auf die Welle 6 aufgewickelt. Nun wird das neu beladene Magazin in das entsprechende Fach der Vorrichtung eingesetzt.The mode of operation of the exemplary embodiment shown of a storage magazine 2 according to the invention will now be described for a better understanding of the invention. To reload an empty magazine 2, both the input opening by opening the slide cover 2b and the take-up shaft 6 are opened by opening the rear wall 2d. Then the wrapping 4 of the film stack which has already been removed is drawn off from the winding shaft 6 and a stiffening and holding box provided under the empty stack is removed from the box. The latter has a raised stop on the back. The holding box ( * ) together with the stop serves to prevent the stack or individual sheets from being displaced when the cover 4 is removed from the stack in a closed magazine 2 by being carried along by the cover. A new film stack including the wrapping 4 is then inserted into the box 2a through the input opening, the take-up flap 4a being guided into the area of the take-up shaft 6 and being clamped onto the take-up shaft 6 by means of the clamps 7. The closing flap 4b of the sheathing in the direction of insertion 3 of the magazine 2a into the device 1 should be able to be torn off in a simple manner when the magazine 2 is closed and is therefore used as a tear-open tab 4b designated. This tear-open tab 4b is thus placed with the magazine 2 open so that it looks out of the magazine between the tear-off bar and the surface of the end face of the box 2h after the magazine has been closed. This position is shown in Figures 1 and 2. Then the crank 10 is swung out and the rear wall 2d is also closed, cf. Figures 1 and 2. Finally, the tear tab 4b is separated by hand along and along the tear bar. Thus, the cover 4 in the closed magazine 2 is open on the front side, so that it can now be pulled off to the rear without any noticeable expenditure of force. Therefore, the crank 10 is now moved, whereby the shaft 6 is rotated. The take-up flap 4a and sheathing 4 are preferably completely wound onto the shaft 6. Now the newly loaded magazine is inserted into the corresponding compartment of the device.

Bei dem insoweit beschriebenen Magazin 2 ist es nun nicht möglich zu erkennen, ob die Aufwicklung der Umhüllung auf die Aufwickelwelle 6 und damit das Abziehen der Umhüllung 4 vom Stapel tatsächlich ordnungsgemäß stattgefunden hat. Es wäre beispielsweise nicht erkennbar, wenn sich beim Drehen der Kurbel 10 die Laschen 4a von der Aufwickelwelle 6 gelöst hätten und die Umhüllung nicht von Stapel abgezogen worden wäre, was zu erheblichen Funktionsstörungen in der Vorrichtung zum Ent- und Beladen der Filmkassetten führend wurde. Daher wird nun eine erfindungsgemäße Anzeigevorrichtung zum Anzeigen eines ordnungsgemäßen Aufwickelns der Umhüllung auf die Aufwickelwelle 6 beschrieben.In the magazine 2 described so far, it is now not possible to see whether the wrapping of the wrapping on the winding shaft 6 and thus the removal of the wrapping 4 from the stack has actually taken place properly. For example, it would not be recognizable if, when the crank 10 was rotated, the tabs 4a detached from the take-up shaft 6 and the casing had not been removed from the stack, which led to considerable malfunctions in the device for unloading and loading the film cassettes. Therefore, a display device according to the invention for displaying a correct winding of the wrapping onto the winding shaft 6 will now be described.

Das Prinzip dieser Anzeigevorrichtung beruht darauf, daß ein lichtdicht geführtes, radial zur Aufwickelwelle 6 bewegliches Abtastglied 15 an der Aufwickelwelle federnd anliegt. Nimmt nun der Durchmesser der Aufwickelwelle 6 infolge der darauf aufgewickelten Umhüllung 4 zu, so wird das Abtastglied 15 radial von der Aufwickelwelle 6 nach außen gedrückt. Diese Bewegung kann nun direkt oder über ein mit dem Abtastglied 15 gekoppeltes Anzeigeglied 16 in einem Betrachtungsfenster 17 angezeigt werden. Das Betrachtungsfenster 17 ist in dem Magazinteil anzuordnen, in dem die Aufwickelwelle 6 gelagert ist, gemäß dem gezeigten Ausführungsbeispiel also an der aufklappbaren Rückwand 2d.The principle of this display device is based on the fact that a light-tightly guided, radially movable to the winding shaft 6 scanning element 15 rests resiliently on the winding shaft. If the diameter of the winding shaft 6 now increases as a result of the sheathing 4 wound thereon, the scanning member 15 is pressed radially outward by the winding shaft 6. This movement can now be displayed directly or via a display element 16 coupled to the scanning element 15 in a viewing window 17. The viewing window 17 is to be arranged in the magazine part in which the take-up shaft 6 is mounted, that is, according to the exemplary embodiment shown, on the hinged rear wall 2d.

Dabei muß zwischen dem Betrachtungsfenster 17 bzw. dem Wandteil, in dem das Betrachtungsfenster 17 angeordnet ist, und der Aufwickelwelle 6 eine lichtdichte Zwischenwand 2i vorgesehen sein, durch die das Abtastglied 15 lichtdicht und beweglich hindurchgeführt ist. Hierzu können alle bekannten, geeigneten lichtdichten Durchführungen, wie Labyrinthstufen oder Dichtringe aus Filz oder Kunststoff, verwendet werden, so daß auf die lichtdichte Lagerung nicht weiter eingegangen wird.In this case, a light-tight intermediate wall 2i must be provided between the viewing window 17 or the wall part in which the viewing window 17 is arranged and the winding shaft 6, through which the scanning member 15 is guided in a light-tight and movable manner. For this purpose, all known, suitable light-tight bushings, such as labyrinth steps or sealing rings made of felt or plastic, can be used, so that light-tight storage is not discussed further.

Gemäß dem gezeigten Ausführungsbeispiel ist das Betrachtungsfenster 17 in der rückwärtigen Magazinstirnseite bzw. der Rückseite der Rückwand 2d angeordnet. Das Abtastglied ist als ein durch die zur Rückseite parallele Zwischenwand 2i lichtdicht hindurchgeführter, hierzu senkrecht beweglicher Stift 15 ausgeführt. Als Anzeigeglied 16 dient ein Sektor einer dünnen Trommel, der um eine zur Stiftachse und zur Achse der Aufwickelwelle 6 senkrechte Achse 18 um ein ausreichendes Winkelstück drehbar ist. Eine im wesentlichen radiale Begrenzung 16a des Trommelsektors 16 weist eine vorstehende Nocke 16b auf, die am der Aufwickelwelle 6 abgewandten Ende 15a des Abtaststiftes 15 unter der Wirkung einer Feder 19 anliegt. Die andere im wesentlichen radiale Begrenzung 16c des Trommelsektors 16 weist eine Stufe 16d mit einem Lager- und Führungszapfen 16e für die als Schraubenfeder ausgebildete Feder 19 auf. Ein weiterer Lager- und Führungszapfen 2k für die Feder 19 ist an der dem Betrachtungsfenster 17 zugewandten Seite der Zwischenwand 2i vorgesehen. Beide Lager-und Führungszapfen 16e und 2k greifen von beiden Stirnseiten in die Schraubenfeder 19 ein und führen und lagern diese hierdurch.According to the exemplary embodiment shown, the viewing window 17 is arranged in the rear end of the magazine or the rear of the rear wall 2d. The scanning element is designed as a pin 15 which is guided through the partition 2i parallel to the rear in a light-tight manner and is movable perpendicularly to it. A sector of a thin drum serves as display element 16 and can be rotated about a sufficient angle piece about an axis 18 perpendicular to the pin axis and the axis of the winding shaft 6. A substantially radial boundary 16a of the drum sector 16 has a protruding cam 16b which bears against the end 15a of the scanning pin 15 facing away from the winding shaft 6 under the action of a spring 19. The other essentially radial boundary 16c of the drum sector 16 has a step 16d with a bearing and guide pin 16e for the spring 19 designed as a helical spring. Another bearing and guide pin 2k for the spring 19 is provided on the side of the intermediate wall 2i facing the viewing window 17. Both bearing and guide pins 16e and 2k engage in the helical spring 19 from both ends and guide and support them as a result.

Damit nun der Trommelsektor 16 geführt und ein Anschlag für die Feder 19 vorhanden ist, ist die Innenseite des das Betrachtungsfenster 17 aufweisenden Wandteiles der Rückwand 2d ein Stück weit als zur Mantelfläche des Trommelsektors 16 komplementäres Außenlagerteil 2f ausgebildet, in dem die Mantelfläche des Trommelsektors 16 hin- und hergleiten kann. Die radiale Begrenzung 16c des Trommelsektors 16 steht dabei radial über die Mantelfläche vor und bildet hierdurch zusammen mit der radialen Begrenzung des Lagerteiles 2f einen Anschlag 16f.So that the drum sector 16 is now guided and a stop for the spring 19 is present, the inside of the wall part of the rear wall 2d which has the viewing window 17 is designed to a certain extent as an outer bearing part 2f which is complementary to the outer surface of the drum sector 16 and in which the outer surface of the drum sector 16 - and can slide away. The radial boundary 16c of the drum sector 16 projects radially beyond the lateral surface and thereby forms a stop 16f together with the radial boundary of the bearing part 2f.

Im Ausgangsstand vor dem Einlegen eines Filmpacks liegen die Nocke 16b unter der Wirkung der Feder 19 am Abtaststift 15 und dieser an der Aufwickelwelle 6 an. Werden eine Umhüllung 4 mit ihren Befestigungslaschen 4a an der Aufwickelwelle 6 befestigt, vgl. Figur 2, die Rückwand 2d geschlossen und die Kurbel 10 gedreht, so wird normalerweise die Umhüllung 4 auf die Aufwickelwelle 6 aufgewickelt. Durch die Zunahme des Wickeldurchmessers wird der Abtaststift 15 nach außen gedrängt und dreht den Trommelsektor 16 entgegen dem Uhrzeigersinn. Diese Bewegung kann als Anzeige für ein ordnungsgemäßes Aufwickeln der Umhüllung 4 im Betrachtungsfenster 17 beobachtet werden. Es kann hierzu zweckmäßig sein, daß die Trommelmantelfläche parallel zu den Mantellinien ein Strichmuster oder längs ihres Umfanges eine Skala aufweist, so daß die Bewegung des Trommelsektors 16 bzw. das völlige Abziehen der Umhüllung 4 vom Filmstapel gut erkennbar ist.In the initial state before the insertion of a film pack, the cams 16b rest under the action of the spring 19 on the scanning pin 15 and this on the winding shaft 6. If a sheathing 4 is fastened to the winding shaft 6 with its fastening tabs 4a, cf. 2, the rear wall 2d is closed and the crank 10 is rotated, the covering 4 is normally wound onto the winding shaft 6. Due to the increase in the winding diameter, the stylus 15 is pushed outward and rotates the drum sector 16 counterclockwise. This movement can be observed as an indication of a proper winding of the wrapping 4 in the viewing window 17. For this purpose, it may be expedient for the drum jacket surface to have a line pattern parallel to the jacket lines or a scale along its circumference, so that the movement of the drum sector 16 or the complete removal of the casing 4 from the film stack can be seen clearly.

Wenn das Betrachtungsfenster nicht gemäß Figur 3 in der Rückseite der Rückwand 2d, sondern in einem hierzu senkrechten oberen oder unteren Wandteil der Rückwand 2d, jedoch wiederum außerhalb der Zwischenwand 2i oberhalb des Endes 15a des Stiftes 15 angeordnet ist, kann auch der Stift 15 selbst als Anzeigemittel verwendet werden. Er müßte dann entsprechend länger sein und beispielsweise eine Skala längs seiner Längsausdehnung aufweisen. Die Andruckfeder könnte dabei dann einfach als Druckfeder zwischen dem Stiftende 15a und der rückwärtigen Stirnseite der Rückwand 2d eingespannt sein.If the viewing window is not arranged in accordance with FIG. 3 in the rear of the rear wall 2d, but in an upper or lower wall part of the rear wall 2d perpendicular thereto, but again outside the intermediate wall 2i above the end 15a of the pin 15, the pin 15 itself can also be used as Display means are used. It would then have to be correspondingly longer and, for example, have a scale along its longitudinal extent. The pressure spring could then simply be clamped as a compression spring between the pin end 15a and the rear end face of the rear wall 2d.
