Abstract

The slotted surface (1), e.g. a support table, has a row of rectangular slots (3a) which are spaced so taht the two shoulders of a film spool (5a, 5b) can be positioned in two of the slots (3a), to hold the spool (5a, 5b) in position while the film web is wound off. A pair of transport rollers (2) are positioned at the opposite side of the slotted surface (1) which are rotated in opposite directions so that the film web is fed through the nip between them, the slots (3a) allowing the film spool (5a, 5b) to rotate in a clockwise direction as the web is fed off. Preferably several pairs of slots with different spacings between them are provided, for receiving different types of spools.

Description

Durchlaufentwi¢klungsmaschine mit Walzentransportsystem Die Erfindung bezieht sich auf eine Durchlaufentwicklungsmaschine mit Walzentransportsystem für blattförb mige photographische Schichtträger.Continuous developing machine with roller transport system The invention refers to a continuous processor with a roller transport system for Leaf-shaped photographic support.

Entwicklungsmaschinen dieses Typs werden im großen Umfang für die Entwicklung von Röntgen-Planfilmen eingesetzt. Da jedoch in vielen Röntgenlabors auch REintgenrollfilme zur Verarbeitung anfallen, ist es bekannt, auf dem Eingabetisch für die Flanfilme bei Anfall von Rollfilmen eine gesonderte Abwickeleinrichtung zu montieren, Die Montage einer solchen Zusatzeinrichtung muß sehr exakt erfolgen, damit ein paralleler Transport der Filmbahn garantiert ist, weil es andernfalls zu Transportstörungen und damit verbundenen Beschädigungen des Filmmaterials kommen kann. Das Ausrichten der Zusatzeinrichtung ist besonders dann schwierig und zeitaufwendigy wenn das Umrüsten der Maschine im verdunkelten Raum erfolgen muß.Developing machines of this type are used on a large scale for the Development of X-ray flat films used. However, as in many X-ray laboratories Also REintgenrollfilme incurred for processing, it is known to be on the input table a separate unwinding device for flan films when roll films are produced to assemble, The assembly of such an additional device must be carried out very precisely, so that a parallel transport of the film web is guaranteed, because otherwise it would transport disruptions and the associated damage to the film material can. Aligning the accessory is particularly difficult and time consuming if the machine has to be converted in a darkened room.

Vorliegender Erfindung liegt nun die Aufgabe zugrunde, den Eingabetisch einer Durchlaufentwicklungsmaschine mit Walzentransportsystemso zu gestalten, daß eine Umrüstung beim Übergang von Plan- auf Rollfilm bzw. auch umgekehrt entfallen kann.The present invention is based on the task of the input table a continuous developing machine with a roller transport system so that there is no need to change over from flat to roll film or vice versa can.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß in den dem Einzugswalzenpaar vorgeordneten Eingabetisch zwei in Transportrichtung verlaufende Schlitze oder schlitzartige Vertiefungen eingearbeitet sind, die zur Aufnahme der beiden Flansche einer Rollfilmspule dienen, Durch vorstehendes Lösungsprinzip entfällt eine relativ aufwendige Abwickelvorrichtung als Zusatzgerät sowie deren montage bzw. Demontage beim wechsel der Filmart.According to the invention this object is achieved in that in the Feed roller pair upstream input table two running in the transport direction Slots or slot-like depressions are incorporated to accommodate the serve both flanges of a roll film reel, With the above solution principle there is no need for a relatively complex unwinding device as an additional device or its assembly or disassembly when changing the type of film.

In Weiterbildung des Gegenstandes der Erfindung können quer zur Transportrichtung mehrere Uchlitzpaare in den Eingabetisch eingearbeitet sein, so daß also eine gleichzeitige Bearbeitung von mehreren Filmbahnen möglich ist.In a further development of the subject matter of the invention, transverse to the transport direction several pairs of Uchlitzpaare be incorporated into the input table, so that a simultaneous Processing of several film webs is possible.

Die Schlitze können weiterhin mit unterschiedlichen Abständen in den Eingabe tisch eingearbeitet sein, um Filmbahnen verschiedener Breite verarbeiten zu können.The slots can still be at different distances in the Input table to be incorporated to process film webs of different widths to be able to.

Zwecks Erzielung eines friktionierten Abwickelvorganges können weiterhin die Schlitze dem Radius der Spulenwalze angepaßt und/oder mit einem reibungsfördernden Belag ausgelegt sein.In order to achieve a frictional unwinding process can continue the slots adapted to the radius of the bobbin roller and / or with a friction-enhancing Covering should be laid out.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt, Es zeigen: Fig. 1 eine Ansicht in perspektivischer Darstellungsweise Fig. 2 eine Draufsicht mit abgewandelter Schltzanordnung Von einer an sich bekannten Durchlaufentwicklungsmaschine mit Walzentransportsystem sind in der Zeichnung lediglich der Eingabetisch 1 und das Einzugswalzenpaar 2 dargestellt, In die Auflagenfläche des Eingabetisches 1 sind zwei Schlitze 3 eingearbeitet, welche die Flansche 4 einer Rollfilmspule 5 aufnehmen. Die Länge dieser Schlitze entspricht etwa dem Radius der Flansche und ihre Breite etwa der Flanschdicke. Die Rollfilmspule 5 wird in die Schlitze 3 s0 eingesetzt, daß sie sich beim Abwickelvorgang in Pfeilrichtung dreht.An embodiment of the invention is shown in the drawing, The figures show: FIG. 1 a view in a perspective representation; FIG. 2 a Top view with modified slot arrangement of a known continuous developing machine with a roller transport system are only the input table 1 and in the drawing the pair of infeed rollers 2 is shown, in the support surface of the infeed table 1 two slots 3 are incorporated, which the flanges 4 of a roll film reel 5 take up. The length of these slots corresponds approximately to the radius of the flanges and their width about the flange thickness. The roll film spool 5 is s0 in the slots 3 used so that it rotates in the direction of the arrow during the unwinding process.

Beim Ausführungsbeispiel gemäß Fig,2 sind zwei Schlitzpaare quer zur Transportrichtung in den Eingabetisch eingearbeitet, so daß zwei Rollfilmspulen 5a, 5b eingesetzt werden können. Ein mittig angeordneter Schlitz 3a gestattet zusammen mit einem der äußeren Schlitze die Verarbeitung einer Filmbahn größerer Breite.In the embodiment according to FIG. 2, two pairs of slots are transverse to Transport direction incorporated into the input table, so that two roll film spools 5a, 5b can be used. A centrally arranged slot 3a allows together with one of the outer slots the processing of a film web of greater width.
