1. Storage device for sheet films which are supplied from a sheet film supply device, preferably a sheet film cassette unloading device, to be carried forward to a sheet film processing apparatus, preferably a development apparatus, in which a stepwise rotating storage means comprising radially extending compartments spaced apart by lugs serves for the separate reception of each sheet film arriving from the supply device and in which after each compartment has travelled along a certain path a sheet film temporarily stored therein can be removed therefrom and carried forward, characterised in that the storage means is formed by an endless conveyor belt (15) moving over two rollers (16, 17) and having compartments (15a) extending radially or perpendicularly from said belt, and in that the compartments are formed by springy clamping jaws (15a) each having at least one lug (15b) projecting against an adjacent clamping jaw, in that the clamping jaws (15a), i.e. a clamping jaw (15a) and a lug (15b) from an adjacent clamping jaw, bear resiliently against one another in the region of the straight part of the path of the conveyor belt (15) between the rollers (16, 17) and are spread out in the region of the circularly curved part of the path of the conveyor belt (15) over the rollers (16, 17) and in that the supply device (9, 10) for sheet films (3) is arranged above the first of the spread out clamping jaws (15a) before the straight line path of the conveyor belt (15) and the removal device (18, 21) is arranged after the foremost unspread clamping jaw of this straight part of the path.

Description

Die Erfindung betrifft eine Speichervorrichtung für aus einer Blattfilmzuführvorrichtung, vorzugsweise einer Blattfilmkassetten-Entladevorrichtung, zugeführten und an ein Blattfilmverarbeitungsgerät, vorzugsweise ein Entwicklungsgerät, weiterzutransportierende Blattfilme, bei der ein schrittweise umlaufendes Speichermittel mit radialen, voneinander mittels Nocken beabstandeten Fächern zur voneinander getrennten Aufnahme der von der Zuführvorrichtung kommenden Blattfilme dient und bei der nach einem bestimmten Transportweg eines jeden der Fächer ein darin zwischengespeicherter Blattfilm diesem entnehmbar und weitertransportierbar ist.The invention relates to a storage device for sheet films fed from a sheet film feed device, preferably a sheet film cassette unloading device, and to be transported to a sheet film processing device, preferably a developing device, in which a step-by-step storage means with radial compartments spaced apart by cams for the separate reception of the from the Sheet film coming feeder is used and in which, after a certain transport path of each of the compartments, a sheet film temporarily stored therein can be removed and transported further.

Eine Vorrichtung dieser Art ist durch die DE-PS 12 87 929 bekannt. Dabei dient als Speichermittel eine mit radialen Fächerblättern, die unabhängig voneinander drehbar sind, besetzte Walze, wobei jeweils das zur nächstfolgenden Blattentnahme anstehende Fach und hinter diesem die weiteren Fächer mittelbar an einem Anschlag zurückgehalten werden, bis die weiterverarbeitende Maschine das nächste Blatt aufnehmen kann. Dabei können nur von oben in die Fächer fallende und bei entsprechender Fachdrehung nach unten weggleitende Blätter gespeichert werden. Durch die drehbar an der Walze angeordneten Fächer ist diese Anordnung darüber hinaus teile- und montageaufwendig.A device of this type is known from DE-PS 12 87 929. A roller with radial fan blades, which can be rotated independently of one another, serves as the storage means, in each case the tray waiting for the next sheet removal and the other trays behind it are held back indirectly at a stop until the further processing machine can pick up the next sheet. It is only possible to save sheets falling into the compartments from above and sliding downwards with the appropriate rotation of the compartment. Due to the rotatably arranged compartments on the roller, this arrangement is also expensive in terms of parts and assembly.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, eine Speichervorrichtung der eingangs genannten Art so auszubilden, daß die einzelnen Fächer nacheinander jeweils eine geöffnete Einführstellung, eine klemmende Speicher- und Transportstellung und eine wiederum geöffnete Entnahmestellung für die Filme durchlaufen, wobei die zu speichernden Blattfilme parallel zueinander und daher sauber getrennt in den Fächern angeordnet sind.In contrast, the invention has for its object to provide a storage device of the type mentioned in such a way that the individual compartments successively each pass through an open insertion position, a clamping storage and transport position and an again opened removal position for the films, the sheet films to be stored being parallel to one another and are therefore neatly arranged in the compartments.

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.

Die Erfindung wird anhand einer Zeichnung näher erläutert. Die einzige Figur zeigt eine Seitenansicht einer erfindungsgemäßen Speichervorrichtung bei abgenommener Seitenwand.The invention is explained in more detail with reference to a drawing. The single figure shows a side view of a storage device according to the invention with the side wall removed.

In der Figur ist das Gehäuse einer Speichervorrichtung mit 1 bezeichnet. Die Speichervorrichtung ist beispielsweise ansetzbar an ein bekanntes Röntgenfilmkassetten-Entladegerät 2, in dem Blattfilme 3 beispielsweise mittels eines Saugers 4 aus einer vorher im Gerät 2 geöffneten Kassette 5 entnommen und einem Transportwalzenpaar 6, 7 zugeführt werden. Mittels dieses Walzenpaares 6, 7 wird ein Blattfilm 3 durch einen dem Entladegerät 2 und der Speichervorrichtung 1 gemeinsamen Schlitz la und eine Leitfläche 8, die den Film 3 vor dem aus der Bahn Fallen bewahrt, einem Einzugstransportwalzenpaar 9, 10 in der Speichervorrichtung zugeführt. Oberhalb der Walze 9 zwischen Film 3 und Gehäusewand lb führt eine weitere Leitfläche 11 für einen durch das Walzenpaar 9, 10 nach oben geförderten Film 3 schräg nach innen und oben und in einem Bogen schließlich zu der unteren Walze 12 eines Auszugstransportwalzenpaares 12, 13. Hinter diesem ist eine weitere Führung 14 angeordnet, die zu dem Austrittsschlitz lc der Vorrichtung 2 führt. Hinter dem Austrittschlitz lc kann beispielsweise eine Entwicklungsmaschine für die Filme 3 angeschlossen sein. Zwischen letzterem und dem Entladegerät 2 können in bekannter und daher nicht gezeigter Weise Vorratsmagazine für Filme vorgesehen sein, von denen in ebenfalls nicht gezeigter, weil bekannter und hier nicht wesentlicher Weise ein neuer Film in eine entleerte Kassette 5 eingebracht werden kann.In the figure, the housing of a storage device is designated by 1. The storage device can be attached, for example, to a known X-ray film cas set unloading device 2, in which sheet films 3 are removed, for example by means of a suction device 4, from a cassette 5 previously opened in device 2 and fed to a pair of transport rollers 6, 7. By means of this pair of rollers 6, 7, a sheet film 3 is fed through a slot 1a common to the unloading device 2 and the storage device 1 and a guide surface 8, which prevents the film 3 from falling out of the web, to a pair of feed transport rollers 9, 10 in the storage device. Above the roller 9 between the film 3 and the housing wall 1b, a further guide surface 11 for a film 3 conveyed upwards by the pair of rollers 9, 10 leads obliquely inwards and upwards and finally in an arc to the lower roller 12 of a pair of pull-out transport rollers 12, 13 behind a further guide 14 is arranged there, which leads to the outlet slot 1c of the device 2. For example, a processor for the films 3 can be connected behind the exit slot 1c. Between the latter and the unloading device 2, storage magazines for films can be provided in a known and therefore not shown manner, of which a new film can also be inserted into an emptied cassette 5 in a manner that is also not shown because it is known and not essential here.

Unterhalb des Einzugstransportwalzenpaares 9, 10 ist ein endloses Transportband 15 über zwei Transportrollen 16, 17 gespannt und als Speichermittel für zwischen dem Entladegerät 2 und der Entwicklungsmaschine zu speichernde Filme 3 ausgebildet. Dieses Speicherband 15 weist in gleichmäßigen Abständen Fächer 15a auf, die im Bereich der Rollen 16, 17 radial zu diesen und zwischen den Rollen 16, 17 senkrecht zum Transportband 15 abstehen. Die Fächer 15a sind als schwach federnde Klemmbacken ausgebildet und tragen zum Klemmen der einzelnen Blattfilme 3 je wenigstens eine Nocke 15b, wobei die Nocken 15b alle nach derselben Seite schauen. Sie sind so dick, daß sie im jeweils geradlinig verlaufenden Teil des Speicherbandes 15 an dem vorhergehenden (oder ggf. auch nachfolgenden) Klemmbacken anliegen und so einen Blattfilm 3 zwischen sich und dem vorhergehenden (oder nachfolgenden) Klemmbacken einklemmen können. Die Rollen 16, 17 bzw. ggf. auch nur eine von ihnen werden durch einen bekannten und daher nicht gezeigten Elektromotor in Richtung weg von den Einzugstransportwalzen 9, 10 angetrieben, so daß der diesen benachbarte Bereich des Speicherbandes 15 von diesen wegbewegt wird in Richtung des Pfeiles 18. Die Einzugstransportwalzen 9, 10 liegen dabei - in Transportrichtung gesehen - etwa in der Verlängerung des ersten abgespreizten Klemmbackens 15a hinter dem geradlinigen Stück des Speicherbandes 15.Below the pair of feed transport rollers 9, 10, an endless conveyor belt 15 is stretched over two transport rollers 16, 17 and is designed as a storage means for films 3 to be stored between the unloading device 2 and the developing machine. This storage tape 15 has compartments 15a at regular intervals, which in the Project area of the rollers 16, 17 radially to these and between the rollers 16, 17 perpendicular to the conveyor belt 15. The compartments 15a are designed as weakly resilient clamping jaws and each carry at least one cam 15b for clamping the individual sheet films 3, the cams 15b all looking towards the same side. They are so thick that they abut the previous (or possibly also subsequent) clamping jaws in the rectilinear part of the storage tape 15 and can thus clamp a sheet film 3 between them and the previous (or subsequent) clamping jaws. The rollers 16, 17 or possibly only one of them are driven by a known and therefore not shown electric motor in the direction away from the feed transport rollers 9, 10 so that the region of the storage belt 15 adjacent to them is moved away from them in the direction of the Arrow 18. The feed transport rollers 9, 10 lie - seen in the transport direction - approximately in the extension of the first spread jaw 15a behind the straight piece of the storage belt 15.

In Transportrichtung gesehen, vor dem Anfang des geradlinigen Teils des Speicherbandes 15, und zwar vor dem Zwischenraum 15d zwischen dem ersten senkrecht stehenden Klemmbacken und dem davorliegenden aufgespreizten Klemmbacken über der Rolle 17 ist eine Hebevorrichtung angeordnet zum Anheben des vordersten, transportierten, gespeicherten Blattfilms 3'. Diese besteht aus einer vertikal angeordneten endlosen Zahnkette 18, die über Zahnrollen 19, 20 angetrieben wird. An dem dem Speicherband 15 zugewandten vertikalen Stück der Zahnkette 18 ist eine Klaue 21 mit einer den Blattunterkanten zugewandten Kerbe 21a befestigt, die durch die Zahnkette 18 auf- und abwärts bewegbar ist. Die Klaue 21 ist in ihrer untersten, eine Blattfilmkante untergreifenden Stellung strichpunktiert und in ihrer obersten Stellung ausgezogen gezeichnet und bewegt sich in einem Schlitz 22a eines rückwärtigen Leitblechs 22, das von der vordersten Stellung des Blattes 3' gerade nach oben und dann in einem Bogen zu den Auszugswalzen 12, 13 führt. Die Leitbleche 11 und 22 verlaufen also trichterähnlich zu den Auszugswalzen 12, 13.Seen in the transport direction, in front of the beginning of the rectilinear part of the storage tape 15, namely in front of the space 15d between the first vertical clamping jaws and the spread jaws above it, above the roller 17, a lifting device is arranged for lifting the foremost, transported, stored sheet film 3 '. . This consists of a vertically arranged endless toothed chain 18 which is driven by toothed rollers 19, 20. On the vertical piece of the toothed chain 18 facing the storage belt 15 there is a claw 21 with one of the bottom edges of the sheet facing notch 21a attached, which is movable up and down by the toothed chain 18. The claw 21 is dash-dotted in its lowermost position under a sheet film edge and drawn in its uppermost position and moves in a slot 22a of a rear guide plate 22 which goes straight up from the foremost position of the sheet 3 'and then in an arc the pull-out rollers 12, 13 leads. The guide plates 11 and 22 thus run in a funnel-like manner to the pull-out rollers 12, 13.

Wird nun aus einer Kassette 5 ein Blattfilm 3 entnommen und dem Einzugswalzenpaar 9, 10 zugeführt, so wird dieses mittels einer geeignet angeordneten, bekannten Lichtschranke 23 eingeschaltet, erfaßt das Blatt und transportiert es entlang des Leitblechs 11 schräg über das geradlinige Stück des Speicherbandes 15 in Richtung der angegebenen Pfeilspitze nach oben. Die untere Walze 10 weist an ihrem Umfang in gleichmäßigen Abständen Kerben 10a auf. Ist das Blatt 3 fast aus dem Walzenpaar 9, 10 herausgelaufen, so fällt seine Unterkante in die nächstliegende Kerbe 10a ein und wird von dieser noch über den oberen Scheitelpunkt der Walze 10 und weiter wieder herunter bis in den unmittelbar darunter liegenden Zwischenraum 15c zwischen der abgespreizten Klemmbacke und der letzten senkrecht stehenden Klemmbacke befördert. Schließlich fällt es in diesen Zwischenraum 15c. Nun wird der nicht gezeigte Antrieb des Speicherbandes 15 bzw. der Rollen 16, 17 eingeschaltet und bewegt über bekannte Steuermittel die Klemmbacken 15a um einen Abstand zwischen ihnen weiter. Dabei wird das eben zugeführte Blatt 3 durch das sich Senkrechtstellen des ursprünglich abgespreizten Klemmbackens eingeklemmt. Folgt kein weiterer Blattfilm mehr nach, so werden die Einzugswalzen 9, 10 wieder abgeschaltet; das Speicherband wird jedoch schrittweise weiterbewegt, bis das eingespeicherte Blatt an der Hebevorrichtung 21 angelangt ist. Folgen weitere Blattfilme 3 aus der Entladevorrichtung nach, so werden sie in der bereits beschriebenen Weise nacheinander zwischen die Klemmbacken 15a des Speicherbandes 15 eingebracht und somit einzeln nacheinander gespeichert. Erreicht das vorderste Blatt 3 seine Entnahmestellung und gibt die Entwicklungsvorrichtung ein Signal, daß sie verarbeitungsbereit ist, dann wird über wiederum im Prinzip bekannte Antriebs- und Steuermittel die Hebevorrichtung 18, 21 in Betrieb gesetzt und transportiert dieses vorderste Blatt 3' zu den Auszugswalzen 12, 13 und weiter durch den Austrittsschlitz lc. An den Auszugswalzen können wiederum Lichtschranken 24 vorgesehen sein, durch die die Hebevorrichtung 21 nach dem Durchgang des Blattes umschaltbar ist zum Rückwärtslauf in die Ausgangsstellung. Bei Dauerbetrieb müssen die Antriebe für das Speicherband 15, die Hebevorrichtung 21 und die Entwicklungsvorrichtung entsprechend durch an sich bekannte und daher nicht gezeigte Steuermittel synchronisiert sein.If a sheet film 3 is now removed from a cassette 5 and fed to the feed roller pair 9, 10, this is switched on by means of a suitably arranged, known light barrier 23, detects the sheet and transports it along the guide plate 11 obliquely over the straight piece of the storage tape 15 in Direction of the indicated arrowhead upwards. The lower roller 10 has notches 10a on its circumference at regular intervals. When the sheet 3 has almost run out of the pair of rollers 9, 10, its lower edge falls into the next notch 10a and from there is still above the upper vertex of the roller 10 and down again into the space 15c immediately below it between the spread Jaw and the last vertical jaw is conveyed. Finally, it falls into this space 15c. Now the drive, not shown, of the storage belt 15 or of the rollers 16, 17 is switched on and moves the clamping jaws 15a further by a distance between them by means of known control means. The sheet 3 just fed through it Vertical points of the originally spread jaw clamped. If no further sheet film follows, the feed rollers 9, 10 are switched off again; however, the storage tape is moved step by step until the stored sheet has reached the lifting device 21. If further sheet films 3 follow from the unloading device, they are introduced one after the other between the clamping jaws 15a of the storage tape 15 and thus individually stored one after the other. If the foremost sheet 3 reaches its removal position and gives the developing device a signal that it is ready for processing, then the lifting device 18, 21 is put into operation again via drive and control means known in principle and transports this foremost sheet 3 'to the pull-out rollers 12, 13 and further through the outlet slot lc. In turn, light barriers 24 can be provided on the pull-out rollers, by means of which the lifting device 21 can be switched over after the sheet has passed through in order to run backwards into the starting position. In continuous operation, the drives for the storage belt 15, the lifting device 21 and the developing device must be synchronized accordingly by control means known per se and therefore not shown.

Durch die Speichervorrichtung 15 ist es möglich, bei momentanem größerem Anfall an zu entleerenden Kassetten 5 die in ihnen enthaltenen Filme im Speicherband 15 getrennt voneinander einzuspeichern und dann entsprechend der Kapazität der Entwicklungsmaschine weiterzutransportieren und wieder aus der Speichervorrichtung abzuführen. Die Speicherkapazität hängt naturgemäß von der Länge des Speicherbandes 15 bzw. von dessen geradlinigem Stück zwischen den Rollen 16, 17 ab. Diese Länge ist daher an die Verarbeitungsgeschwindigkeit des Entladegerätes und die Kapazität der Entwicklungsmaschine anzupassen, so daß durch das Speicherband ein Puffer gebildet wird.With the storage device 15, it is possible to store the films contained in them separately in the storage belt 15 in the event of a larger number of cassettes 5 to be emptied and then to transport them further according to the capacity of the developing machine and again from the storage device dissipate. The storage capacity naturally depends on the length of the storage tape 15 or on its straight piece between the rollers 16, 17. This length must therefore be adapted to the processing speed of the unloading device and the capacity of the developing machine, so that a buffer is formed by the storage tape.

Wie leicht erkennbar ist, könnte das Speicherband 15 sich quer zur Transportrichtung über die maximale Filmbreite erstrecken und müßte dann an mehreren Stellen Ausnehmungen zum Eingreifen gleichartiger, synchron laufender Heber 21 aufweisen. Nachdem es aber für die zu speichernden Filme nicht günstig wäre, wenn sie über ihre Breite zwischen den Klemmbacken 15a eingeklemmt würden, ist es zweckmäßig, mehrere gleiche schmale Speicherbänder 15 über die ganze Gerätebreite verteilt anzuordnen und jedem Speicherband eine Hebeanordnung zuzuordnen. Die Verteilung der Speicherbänder 15 und Heber 21 muß dabei so vorgenommen werden, daß Filme jeder möglichen Breite von mindestens zwei Speicherbändern und zwei Hebern, die parallel zueinander angeordnet sind und synchron zueinander laufen, erfaßt werden.As can easily be seen, the storage belt 15 could extend across the maximum film width transversely to the direction of transport and would then have to have recesses for engaging similar, synchronously running lifters 21 in several places. However, since it would not be favorable for the films to be stored if their width were to be clamped between the clamping jaws 15a, it is expedient to arrange several identical narrow storage tapes 15 distributed over the entire width of the device and to assign a lifting arrangement to each storage tape. The distribution of the storage tapes 15 and lifters 21 must be carried out in such a way that films of any possible width are captured by at least two storage tapes and two lifters which are arranged parallel to one another and run synchronously with one another.

Es ist zweckmäßig, daß die Walzenpaare 9, 10 und 12, 13 sowie die Speicherbandeinrichtung und die Hebeeinrichtung getrennte Antriebe aufweisen und durch elektronische Steuereinrichtungen die verschiedenen Antriebe gesteuert werden. Dadurch läßt sich erreichen, daß z. B. fünf Filme unmittelbar nacheinander eingegeben werden und das Speicherband entsprechend weiterläuft. Die Hebevorrichtung muß jedoch erst in Tätigkeit treten, wenn der erste der fünf Filme dort angelangt ist. Sie sowie auch die Auszugswalzen 12, 13 arbeiten dann in dem Rythmus weiter, in dem die angeschlossene Entwicklungsmaschine die Filme verarbeiten kann, so daß sich auch das Speicherband dann schrittweise in diesem Rythmus bewegen muß. Die Speicher- oder Puffervorrichtung dient also dazu, vorübergehend mehr Filme aufzunehmen, als momentan weiterverarbeitet werden können, und diese dann im Verarbeitungstempo der Weiterverarbeitungsvorrichtung dieser zuzuführen. Dabei bietet sie den Vorteil, daß die einzelnen, zu speichernden Filme voneinander getrennt gespeichert werden und daher nicht aneinander haften können und auch nicht erst gestapelt und dann wieder vereinzelt werden müssen.It is expedient that the roller pairs 9, 10 and 12, 13 as well as the storage belt device and the lifting device have separate drives and the various drives are controlled by electronic control devices. This can be achieved that z. B. five films can be entered immediately one after the other and the storage tape continues to run accordingly. However, the lifting device only has to start when the first of the five films got there. You and the pull-out rollers 12, 13 then continue to work in the rhythm in which the connected processor can process the films, so that the storage tape must then move gradually in this rhythm. The storage or buffer device thus serves to temporarily record more films than can currently be further processed, and then to feed them to the further processing device at the processing speed. It offers the advantage that the individual films to be stored are stored separately from one another and therefore cannot adhere to one another and also do not have to be stacked and then separated again.

Naturgemäß sind noch andere Ausführungsformen als das in der Figur gezeigte Beispiel möglich. So könnte die Zuführvorrichtung die Blätter auch an der Unterseite der Speicherbänder zuführen, bis sie je zwischen die Klemmbacken geklemmt sind, wobei die Blätter dann am Ende der geraden Transportstrecke einfach nach unten gegen Auszugswalzen fallen könnten. Es wäre aber auch möglich, daß die Blätter direkt von oben in den jeweils gebildeten Spalt 15c fallen oder durch oberhalb desselben angeordnete Transportwalzen eingeführt werden. Schließlich könnte dabei dann jede andere bekannte, für Blätter geeignete Auszugsvorrichtung zwischen den Zwischenräumen 15d der Speicherbänder vorgesehen sein.Naturally, other embodiments than the example shown in the figure are possible. The feed device could also feed the sheets on the underside of the storage belts until they are each clamped between the clamping jaws, the sheets then simply falling down against pull-out rollers at the end of the straight transport path. However, it would also be possible for the sheets to fall directly from above into the gap 15c formed in each case or to be introduced through transport rollers arranged above the latter. Finally, any other known pull-out device suitable for sheets could then be provided between the spaces 15d of the storage tapes.
