Definitions
- the invention relates to a device for developing paper images, which is continuously traversed by the photo paper web to be developed.
- each of the paper images exposed on the photo paper web to be developed must have a certain, constant dwell time, for example 45 seconds.
- the developing device and the developing process are involved in the entire manufacturing and processing process, especially in the case of a more industrial production of photo paper images in large companies in the photo production industry.
- this includes processing the negatives, exposing the photo paper webs and cutting the finished paper photos to their packaging.
- the exposure device for exposing the photographic paper is the most expensive device in the entire work process, which could be driven at a very high work rate on its own, but would have to be throttled constantly because of the subsequent development process if the work was connected. This would not occupy this expensive machine.
- the work performed by the work stations preceding and following the development process changes from time to time.
- the exposure device printer
- the throughput speed in the printer has to be changed.
- the photo paper web to be exposed can be transported per exposure process only by the format length of a paper image, i.e. per exposure process by a shorter distance than before.
- the duration of an exposure process usually remains constant. This has the consequence that the transport speed of the photo paper web has to decrease with a smaller format of the photo paper images. This also changes the workload of this workstation.
- the invention is therefore based on the object of improving the development process in such a way that it fits more profitably into the paper photo production and processing process (finishing).
- the entire work process is advantageously no longer dictated by the development process as in the past, but in the process according to the invention, the speed of the development process is based on the other work stations, so that they are better utilized and thus a higher work rate and profitability are achieved .
- the exposure device and the developing device were connected to one another, but this connection only took place via an intermediate store.
- the exposure device had to adapt to the operating speed of the developing device in an unprofitable manner by filling the memory only to the extent that the developing device could empty it.
- the entire work process had to be brought to a complete standstill temporarily in order to be able to adapt to the new conditions.
- Document DE-A-36 23 084 describes an automatic photo development system in which storage units with continuously variable capacities are arranged between the different process devices, which allow the photo paper tape to be processed continuously despite the different speeds of the processes.
- the development speed of the developing device can depend on the other workstations, so that it is now also advantageously possible to directly connect the exposure device and the developing device, in which the exposure device, when fully utilized, determines the working speed. Only with the device according to the invention does the development process smoothly adapt to the changed speed requirement.
- the development device can also be linked directly to subsequent work stations.
- a certain constant residence time for example 45 seconds, must still be available for each of the paper images exposed on the photo paper web to be developed. This is ensured as long as the transport speed of the photo paper web through the developing device is constant, since the path of the photo paper web through the developing device is also constant and the desired dwell time is adjusted according to the simple formula of the running distance divided by the speed.
- the photo paper web to be exposed is deflected and guided in a meandering manner via deflection rollers. Meandering in order to achieve a sufficiently large throughput path for relatively high transport speeds with the smallest possible space requirement.
- Some of these deflection rollers are detachably arranged in conventional development machines. These deflection rollers can thus be used to change the throughput path into very specific, predetermined ones Positions are implemented.
- these convertible deflection rollers are mounted on plug-in strips on which the deflection rollers can be repositioned and re-screwed.
- a change in the speeds of upstream or downstream workstations is also easily absorbed in the method according to the invention.
- Document SU-A-593 181 describes an automatic imperforate film developing device in which the length of a single loop immersed in the developer is controlled by a sensor so that the duration of the development remains constant even if it changes the entry speed of the film changes.
- the throughput path can be changed by locally changing a plurality of deflection points for the photo paper web in the developing device, by means of which the throughput path is specified, such that the length of the section of the phototapered paper web which they steer and is in the developing device is proportional to the changed transport speed is also changed.
- deflection rollers or the like are continuously changed in their arrangement until the throughput is again adapted to the changed transport speed of the photo paper web, so that the dwell time for the individual exposed paper image in the developing device remains constant.
- the throughput path can be changed slowly up to the proportional value to be achieved. This also ensures that the tension of the paper web does not change too quickly, so that paper tear or paper sagging is avoided.
- the passage is preferably changed automatically by means of suitable control devices, so that workloads are relieved and an optimal adaptation of the passage is achieved.
- the device according to the invention advantageously has displaceably arranged deflection rollers, which can therefore be continuously changed in position, this change in position being able to be carried out with a drive unit, which makes work easier and also has the advantage that the development device does not need to be opened to change the path of travel .
- the adjustment of the throughput path is advantageously carried out automatically, specifically by means of a registration device registering a speed parameter, preferably an input speed parameter, for actuating and actuating the control drive unit in accordance with the registered parameter. It is preferably provided that the output drive unit can also be controlled by the registration device, in particular so that the correct paper tension of the photo paper web is established.
- the registration device registers speed parameters of both drive units and then controls and actuates the control drive unit if there is a speed difference between the two drive units.
- a change in speed is predetermined by the printer connected upstream, when the device according to the invention is used, so that the input speed of the photo paper in the developing device changes accordingly, while the output speed is initially maintained until the deflection rollers have moved to the final position.
- a speed difference can thus be used as a suitable speed parameter for controlling the control drive unit be considered.
- the displaceable deflection rollers can be displaced continuously, preferably on a sliding guide. This has the advantage that the throughput path can also be precisely adapted to slight changes in speed. It would also be conceivable not to move continuously, for example on grid rails or the like.
- drives known per se such as e.g. can be used with chains, spindles or the like.
- a plurality of deflection rollers of the same height level can be moved and are coupled to one another in terms of drive.
- the drive coupling improves controllability and allows a single drive unit to suffice.
- a next development of the invention, for which independent protection is also claimed, is characterized in that the deflecting rollers are arranged in only two height levels, that all deflecting rollers of one of the height levels are coupled with one another and that a displacement of these rollers extends beyond the other height level the other pulleys is possible.
- the deflecting rollers are arranged in two groups, between which the photo paper web runs back and forth in meandering fashion, and that by changing the distance between these two roller groups to one another, the path of travel of the photo paper web is very clean and precise with the greatest possible scope for change can be changed.
- this design has the advantage that when the developing device is started up anew, in front of which an initial section of a new photo paper web is first inserted, this insertion can take place while the displaceable rollers are pushed beyond the height level of the other rollers, so that the initial section between them Rolls can be shot through and when the movable deflection rollers are returned to their original level, a meandering course automatically results over the deflection rollers of the photo paper web.
- the development device can thus be restarted with very little loss of time, for example after maintenance.
- This displacement of the displaceable deflection rollers beyond the height level of the other deflection rollers is particularly simple in a development of the invention, which is characterized in that the deflection rollers of a height level are mechanically connected to each other to form a comb-like roller unit and that the two roller units, if provided to the same height level moved, comb together.
- the displaceable deflection rollers are preferably those which belong to the lower level.
- the paper images are exposed on a photo paper web 1, which runs in loops in a meandering manner over deflection rollers 2a, 2b through the developing device.
- the pulleys 2a, 2b are arranged in two groups at two height levels, the deflection rollers 2a forming the lower deflection roller group and the deflection rollers 2b forming the upper deflection roller group.
- the photo paper web 1 is transported by means of an input drive unit 3 and an output drive unit 4 through the developing device over the deflection rollers 2a, 2b.
- the pulleys of the lower pulley group and the upper pulley group are mechanically connected to each other to form roller units.
- the lower roller unit can be moved up and down along slide guides 5.
- a control drive unit 6 is provided which is drivingly coupled to the lower roller unit via chains 7.
- connecting elements 8 are provided.
- the control drive unit 6 is controlled and actuated by a registration device 9.
- This registration device 9 has sensors 10, which register the speed parameters of the input drive unit 3 and the output drive unit 4.
- the control drive unit 6 can be activated, for example, if the speed parameter of the input drive unit 3 changes or if a difference in the speed parameters of the input and output drive unit occurs.
- the slide guides 5 are so long that they protrude above the level of the upper guide rollers 2b, so that the lower guide rollers 2a can be raised to above the level of the upper guide rollers 2b.
- This uppermost position of the lower deflecting rollers 2a is indicated by dashed lines with the reference numbers 2a 'for some deflecting rollers 2a.
- an initial section can be between these and the upper guide rollers 2b a photo paper web 1 in a simple manner, namely to be shot through when the developing device is to be restarted, for example after maintenance.
- FIG. 2 shows a top view, partly in section, of the device according to FIG. 1.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Entwickeln von Papierbildern, die kontinuierlich von der zu entwickelnden Fotopapierbahn durchlaufen wird.The invention relates to a device for developing paper images, which is continuously traversed by the photo paper web to be developed.
Zum Entwickeln durchläuft eine belichtete Fotopapierbahn bzw. Fotopapierbahnen, die endlos aneinander hängen, eine Entwicklungsvorrichtung. Zur Erzielung eines optimalen Entwicklungsvorganges muß jedem der auf der zu entwickelnden Fotopapierbahn belichteten Papierbilder eine bestimmte, konstante Verweilzeit, beispielsweise 45 Sekunden, zur Verfügung stehen.For development, an exposed photo paper web or photo paper webs that are endlessly connected to one another passes through a developing device. To achieve an optimal development process, each of the paper images exposed on the photo paper web to be developed must have a certain, constant dwell time, for example 45 seconds.
Somit wird die Zeit, die zum Entwickeln der Bilder benötigt wird, quasi von der Chemie des Entwicklungsprozesses diktiert.So the time it takes to develop the images is dictated by the chemistry of the development process.
Die Entwicklungsvorrichtung und der Entwicklungsvorgang sind aber, besonders bei einer mehr industriellen Herstellung von Fotopapierbildern in Großbetrieben der Fotoherstellungsbranche, in den gesamten Herstellungs- und Bearbeitungsprozeß eingebunden. Hierzu gehören neben der Fotopapierentwicklung unter anderem die Bearbeitung der Negative, die Belichtung der Fotopapierbahnen und das Schneiden der fertigen Papierfotos bis hin zu ihrer Verpackung.However, the developing device and the developing process are involved in the entire manufacturing and processing process, especially in the case of a more industrial production of photo paper images in large companies in the photo production industry. In addition to photo paper development, this includes processing the negatives, exposing the photo paper webs and cutting the finished paper photos to their packaging.
Diese der Entwicklungsstation zeitlich vorangehenden oder nachfolgenden Arbeitsstationen könnten jedoch meistens eine höhere Arbeitsleistung erbringen, wenn der gesamte Arbeitsablauf nicht auch den Entwicklungsprozeß beinhalten würde, dem durch die Chemie des Entwickelns das Arbeitstempo vorgegeben wird, an dem sich zwangsläufig auch die übrigen Arbeitsstationen orientieren müssen, um keinen Stau im Entwicklungsprozeß zu verursachen. Die Arbeitsstationen arbeiten normalerweise unabhängig voneinander, um die Auswirkungen der Arbeitstempo-Diskrepanz möglichst gering zu halten.However, these workstations preceding or following the development station could usually be a higher one Perform work if the entire workflow did not include the development process, which is determined by the chemistry of development, the speed at which the other workstations must inevitably be based, so as not to cause a jam in the development process. The workstations normally work independently of one another in order to keep the effects of the work speed discrepancy as low as possible.
Es ist aber auch schon einmal vorgeschlagen worden, die Arbeitsstationen miteinander zu koppeln, dann ist es aber beim Herstellungs- und Bearbeitungsprozeß von Fotopapierbildern so, daß die Entwicklungsvorrichtung die Arbeitsleistung vorbestimmt und alle anderen Arbeitsstationen sich notgedrungen hiernach richten.However, it has also already been proposed to couple the workstations with one another, but then in the production and processing process of photographic paper images it is such that the developing device predetermines the work performance and all other workstations are inevitably based on this.
Dies ist aus Rentabilitätsgründen unbefriedigend. Beispielsweise ist die Belichtungsvorrichtung zur Belichtung des Fotopapiers die teuerste Vorrichtung im gesamten Arbeitsprozeß, die von sich aus in einem sehr hohen Arbeitstempo gefahren werden könnte, aber bei verbundener Arbeitsweise wegen des nachfolgenden Entwicklungsprozesses ständig gedrosselt werden müßte. Diese teure Maschine würde dadurch nicht ausgelastet.This is unsatisfactory for profitability reasons. For example, the exposure device for exposing the photographic paper is the most expensive device in the entire work process, which could be driven at a very high work rate on its own, but would have to be throttled constantly because of the subsequent development process if the work was connected. This would not occupy this expensive machine.
Auch die dem Entwicklungsprozeß nachfolgenden Arbeitsstationen, die zum Teil kostenintensiv mit Arbeitskräften besetzt sind, müßten häufig auf die Entwicklungsvorrichtung in ihrem Arbeitstempo Rücksicht nehmen und wären daher auch nicht immer ausgelastet, wenn sie mit der Entwicklungsvorrichtung verbunden sind. Deshalb hat sich die Verbundfahrweise nicht durchgesetzt.Even the work stations following the development process, which are sometimes costly to employ, would often have to take the development device into account in their work pace and would therefore not always be used to capacity when they are connected to the development device. For this reason, the network mode of operation has not become established.
Hinzu kommt, daß sich die Arbeitsleistungen der dem Entwicklungsprozeß vorangehenden und nachfolgenden Arbeitsstationen im zeitlichen Verlauf hin und wieder ändern. In der vorangehenden Arbeitsstation beispielsweise, weil in der Belichtungsvorrichtung (Printer) andere Papierbildformate belichtet werden, wozu die Durchlaufgeschwindigkeit im Printer geändert werden muß. Wird nämlich das Format der Papierbilder auf der Fotopapierbahn kleiner als das der vorhergehenden, so kann die zu belichtende Fotopapierbahn pro Belichtungsvorgang nur um die Formatlänge eines Papierbildes weitertransportiert werden, also pro Belichtungsvorgang um eine kürzere Wegstrecke als vorher. Die Dauer eines Belichtungsvorganges bleibt normalerweise konstant. Dies hat zur Folge, daß sich die Transportgeschwindigkeit der Fotopapierbahn bei kleinerem Format der Fotopapierbilder verringern muß. Dadurch ändert sich somit auch die Auslastung dieser Arbeitsstation.In addition, the work performed by the work stations preceding and following the development process changes from time to time. In the previous work station, for example, because other paper image formats are exposed in the exposure device (printer), for which the throughput speed in the printer has to be changed. If the format of the paper images on the photo paper web becomes smaller than that of the previous one, the photo paper web to be exposed can be transported per exposure process only by the format length of a paper image, i.e. per exposure process by a shorter distance than before. The duration of an exposure process usually remains constant. This has the consequence that the transport speed of the photo paper web has to decrease with a smaller format of the photo paper images. This also changes the workload of this workstation.
Der Erfindung liegt daher die Aufgabe zugrunde, das Entwicklungsverfahren so zu verbessern, daß es sich rentabler in den Papierfoto-Herstellungs- und Bearbeitungsprozeß (Finishing) einfügt.The invention is therefore based on the object of improving the development process in such a way that it fits more profitably into the paper photo production and processing process (finishing).
Diese Aufgabe wird durch die Vorrichtung gemäß Anspruch 1 gelöst.This object is achieved by the device according to
Aufgrund dieser erfinderischen Maßnahme wird mit Vorteil der gesamte Arbeitsprozeß nicht mehr wie früher vom Entwicklungsprozeß diktiert, sondern bei dem erfindungsgemäßen Verfahren richtet sich der Entwicklungsprozeß in seiner Arbeitsgeschwindigkeit nach den übrigen Arbeitsstationen, so daß diese besser ausgelastet werden und damit eine höhere Arbeitsleistung und Rentabilität erzielt wird.Because of this inventive measure, the entire work process is advantageously no longer dictated by the development process as in the past, but in the process according to the invention, the speed of the development process is based on the other work stations, so that they are better utilized and thus a higher work rate and profitability are achieved .
Bei dem früher vorgeschlagenen Verbundverfahren mußte bei der Foto-Endverarbeitung im Großfinishing auf eine optimale Auslastung verzichtet und der gesamte Arbeitsprozeß dem Diktat des Entwicklungsprozesses unterworfen werden. Deshalb waren die vorhergehenden und nachfolgenden Arbeitsstationen vom Entwicklungsvorgang dadurch abgekoppelt worden, daß die Fotopapierbahnen in Rollen dem Entwicklungsprozeß zugeführt und auch wieder aufgerollt abgeführt wurden.With the previously proposed composite process, optimal utilization of the photo finishing in large-scale finishing had to be dispensed with and the entire work process had to be subjected to the dictates of the development process. Therefore, the previous and subsequent workstations were decoupled from the development process in that the photo paper webs were supplied to the development process in rolls and again were rolled up.
Zum Teil wurden die Belichtungsvorrichtung und die Entwicklungsvorrichtung miteinander verbunden, diese Verbindung fand aber nur über einen Zwischenspeicher statt. Bei dieser indirekten Verbindung mußte sich die Belichtungsvorrichtung, wie bereits eingangs geschildert, in unrentabler Weise an die Arbeitsgeschwindigkeit der Entwicklungsvorrichtung anpassen, indem sie den Speicher immer nur soweit füllte, wie er von der Entwicklungsvorrichtung leergearbeitet werden konnte. Bei Arbeitsgeschwindigkeitsänderungen in der Belichtungsvorrichtung, z.B. durch Formatwechsel, mußte der gesamte Arbeitsprozeß zeitweilig völlig zum Stillstand gebracht werden, um sich den neuen Verhältnissen anpassen zu können.In part, the exposure device and the developing device were connected to one another, but this connection only took place via an intermediate store. With this indirect connection, the exposure device, as already described at the outset, had to adapt to the operating speed of the developing device in an unprofitable manner by filling the memory only to the extent that the developing device could empty it. With changes in working speed in the exposure device, e.g. by changing the format, the entire work process had to be brought to a complete standstill temporarily in order to be able to adapt to the new conditions.
Das Dokument DE-A-36 23 084 beschreibt eine automatische Fotoentwicklunsanlage, in der zwischen die verschiedenen Prozeßvorrichtungen Speichereinheiten mit kontinuierlich variabler Kapazität angeordnet sind, die trotz der verschiedenen Geschwindigkeiten der Prozesse eine anhaltende Bearbeitung des Fotopapierbands erlauben.Document DE-A-36 23 084 describes an automatic photo development system in which storage units with continuously variable capacities are arranged between the different process devices, which allow the photo paper tape to be processed continuously despite the different speeds of the processes.
Bei der erfindungsgemäßen Vorrichtung kann sich die Entwicklungsvorrichtung in ihrer Arbeitsgeschwindigkeit nach den übrigen Arbeitsstationen richten, so daß nun mit Vorteil auch eine direkte Verbindung von Belichtungsvorrichtung und Entwicklungsvorrichtung möglich ist, bei der die Belichtungsvorrichtung, möglichst voll ausgelastet, das Arbeitstempo bestimmt. Erst bei der erfindungsgemäßen Vorrichtung paßt sich der Entwicklungsprozeß gleitend dem geänderten Geschwindigkeitsbedarf an. Die Entwicklungsvorrichtung kann auch direkt mit nachfolgenden Arbeitsstationen verknüpft werden.In the device according to the invention, the development speed of the developing device can depend on the other workstations, so that it is now also advantageously possible to directly connect the exposure device and the developing device, in which the exposure device, when fully utilized, determines the working speed. Only with the device according to the invention does the development process smoothly adapt to the changed speed requirement. The development device can also be linked directly to subsequent work stations.
Zur Erzielung eines optimalen Entwicklungsvorganges muß jedoch nach wie vor jedem der auf der zu entwickelnden Fotopapierbahn belichteten Papierbilder eine bestimmte, konstante Verweilzeit, beispielsweise 45 Sekunden, zur Verfügung stehen. Dies ist gewährleistet, solange die Transportgeschwindigkeit der Fotopapierbahn durch die Entwicklungsvorrichtung konstant ist, da auch der Durchlaufweg der Fotopapierbahn durch die Entwicklungsvorrichtung konstant ist und der gewünschten Verweilzeit nach der einfachen Formel Durchlaufweg geteilt durch die Geschwindigkeit angepaßt ist.In order to achieve an optimal development process, however, a certain constant residence time, for example 45 seconds, must still be available for each of the paper images exposed on the photo paper web to be developed. This is ensured as long as the transport speed of the photo paper web through the developing device is constant, since the path of the photo paper web through the developing device is also constant and the desired dwell time is adjusted according to the simple formula of the running distance divided by the speed.
Probleme bei der Entwicklung treten jedoch auf, wenn sich die Transportgeschwindigkeit der Fotopapierbahn, wie bei der erfindungsgemäßen Vorrichtung, ändern können soll.Development problems arise, however, if the transport speed of the photo paper web is to be able to change, as in the device according to the invention.
Ändert sich nämlich die Transportgeschwindigkeit der Fotopapierbahn in der Entwicklungsvorrichtung, so hätte dies nachteilig zur Folge, daß die belichteten Fotopapierbilder die Entwicklungsvorrichtung in einer falschen Geschwindigkeit durchlaufen, zu schnell oder zu langsam, so daß kein optimaler Entwicklungsvorgang erreicht würde.If the transport speed of the photo paper web in the developing device changes, this would have the disadvantage that the exposed photo paper images pass through the developing device at an incorrect speed, too fast or too slow, so that an optimal development process would not be achieved.
Zwar war es auch bei früheren Entwicklungsvorrichtungen möglich, den Durchlaufweg zu ändern, dies konnte aber nur stufenweise geschehen, und selbst dies wurde, wegen des Umstandes der Umrüstung der Entwicklungsvorrichtung, meist nicht genutzt.Although it was also possible to change the throughput path with earlier development devices, this could only be done in stages, and even this was mostly not used due to the fact that the development device had to be retrofitted.
Bei herkömmlichen Entwicklungsvorrichtungen, siehe z.B. US-A- 3087 405, wird die zu belichtende Fotopapierbahn über Umlenkrollen mäanderartig umgelenkt und geführt. Mäanderartig deshalb, um bei möglichst geringem Platzbedarf überhaupt einen ausreichend großen Durchlaufweg für relativ hohe Transportgeschwindigkeiten zu erreichen. Einige dieser Umlenkrollen sind bei herkömmlichen Entwicklungsmaschinen lösbar angeordnet. Diese Umlenkrollen können somit zur Veränderung des Durchlaufweges in ganz bestimmte, vorgegebene Positionen umgesetzt werden. Beispielsweise sind diese umsetzbaren Umlenkrollen auf Steckleisten montiert, an denen die Umlenkrollen umgesteckt und neu festgeschraubt werden können.In conventional development devices, see for example US-A-3087 405, the photo paper web to be exposed is deflected and guided in a meandering manner via deflection rollers. Meandering in order to achieve a sufficiently large throughput path for relatively high transport speeds with the smallest possible space requirement. Some of these deflection rollers are detachably arranged in conventional development machines. These deflection rollers can thus be used to change the throughput path into very specific, predetermined ones Positions are implemented. For example, these convertible deflection rollers are mounted on plug-in strips on which the deflection rollers can be repositioned and re-screwed.
Diese herkömmliche Verfahrensweise und ebenfalls diese herkömmliche Vorrichtung benötigten somit Umrüstzeiten und Arbeitskräfte, weswegen diese Umrüstung normalerweise gar nicht vorgenommen wurde.This conventional procedure and also this conventional device therefore required changeover times and manpower, which is why this changeover was normally not carried out at all.
Bei Verwendung der erfindungsgemäßen Vorrichtung, bei der der Durchlaufweg kontinuierlich verändert wird, kann mit Vorteil ein solches Umrüsten der Entwicklungsvorrichtung entfallen, so daß die Entwicklungsvorrichtung auch nicht abgeschaltet werden muß, sondern fortdauernd weiter arbeiten kann. Sie ist damit besser ausgelastet und rentabler. Die Arbeitsintensität durch Arbeitskräfte wird verringert, wodurch ebenfalls eine bessere Rentabilität erzielt wird.When using the device according to the invention, in which the throughput path is continuously changed, such a retooling of the development device can advantageously be omitted, so that the development device does not have to be switched off either, but can continue to operate. It is thus better utilized and more profitable. The labor intensity of workers is reduced, which also leads to better profitability.
Auch eine Änderung der Geschwindigkeiten vor- oder nachgeschalteter Arbeitsstationen werden beim erfindungsgemäßen Verfahren ohne weiteres aufgefangen.A change in the speeds of upstream or downstream workstations is also easily absorbed in the method according to the invention.
Das Dokument SU-A-593 181 beschreibt eine automatische Entwicklungsvorrichtung für unperforierten Film, bei dem die Länge einer in der Entwickler getauchten, einzigen, mittels umlenkrollen definierten Schlaufe über einen Sensor kontrolliert wird, so daß die Dauer der Entwicklung konstant bleibt, sogar wenn sich die Eintrittgeschwindigkeit des Filmes ändert.Document SU-A-593 181 describes an automatic imperforate film developing device in which the length of a single loop immersed in the developer is controlled by a sensor so that the duration of the development remains constant even if it changes the entry speed of the film changes.
In der erfindungsgemäßen Vorrichtung ist der Durchlaufweg änderbar, indem mehrere Umlenkpunkte für die Fotopapierbahn in der Entwicklungsvorrichtung, durch die der Durchlaufweg vorgegeben wird, örtlich derart verändert werden, daß die Länge des von ihnen gelenkten, in der Entwicklungsvorrichtung befindlichen Abschnittes der Fototpapierbahn proportional zur geänderten Transportgeschwindigkeit mitgeändert wird.In the device according to the invention, the throughput path can be changed by locally changing a plurality of deflection points for the photo paper web in the developing device, by means of which the throughput path is specified, such that the length of the section of the phototapered paper web which they steer and is in the developing device is proportional to the changed transport speed is also changed.
Bei Verwendung der erfindungsgemäßen Vorrichtung werden also Umlenkrollen oder dergleichen kontinuierlich in ihrer Anordnung verändert, bis der Durchlaufweg wieder der veränderten Transportgeschwindigkeit der Fotopapierbahn angepaßt ist, so daß die Verweilzeit für das einzelne belichtete Papierbild in der Entwicklungsvorrichtung konstant bleibt.When using the device according to the invention, deflection rollers or the like are continuously changed in their arrangement until the throughput is again adapted to the changed transport speed of the photo paper web, so that the dwell time for the individual exposed paper image in the developing device remains constant.
Bei einer zu abrupten Veränderung des Durchlaufweges in der Entwicklungsvorrichtung könnte es passieren, daß insbesondere die letzten belichteten Fotopapierbilder mit dem alten Format, denen Bilder mit geändertem Format nachfolgen, zu lange oder zu kurz, je nachdem wie sich die Transportgeschwindigkeit gerade ändert, in der Entwicklungsvorrichtung verweilen.If the throughput path in the developing device is changed too abruptly, it could happen that, in particular, the last exposed photo paper pictures with the old format, which are followed by pictures with changed format, are too long or too short, depending on how the transport speed is changing, in the developing device linger.
Um diese Gefahr einer nicht optimalen Entwicklung zu minimieren, ist nach einer Weiterbildung der erfindungsgemäßen Vorrichtung vorgesehen, daß der Durchlaufweg langsam bis auf den zu erreichenden Proportionalwert änderbar ist. Hierdurch wird zusätzlich erreicht, daß die Spannung der Papierbahn sich nicht zu schnell ändert, so daß Papierriß oder Papierdurchhängen vermieden wird.In order to minimize this risk of non-optimal development, it is provided according to a further development of the device according to the invention that the throughput path can be changed slowly up to the proportional value to be achieved. This also ensures that the tension of the paper web does not change too quickly, so that paper tear or paper sagging is avoided.
Vorzugsweise wird der Durchlaufweg mittels geeigneter Steuereinrichtungen automatisch geändert, so daß Arbeitskräfte entlastet werden und eine optimale Anpassung des Durchlaufweges erzielt wird.The passage is preferably changed automatically by means of suitable control devices, so that workloads are relieved and an optimal adaptation of the passage is achieved.
Die erfindungsgemäße Vorrichtung weist mit Vorteile verschiebbar angeordnete, Umlenkrollen auf, die daher kontinuierlich lageveränderbar sind, wobei diese Lageveränderung mit einer Antriebseinheit durchgeführt werden kann, was eine Arbeitserleichterung bedeutet und außerdem den Vorteil hat, daß die Entwicklungsvorrichtung zur Veränderung des Durchlaufweges nicht geöffnet zu werden braucht.The device according to the invention advantageously has displaceably arranged deflection rollers, which can therefore be continuously changed in position, this change in position being able to be carried out with a drive unit, which makes work easier and also has the advantage that the development device does not need to be opened to change the path of travel .
Die Durchlaufweganpassung wird mit Vorteil automatisch vorgenommen, und zwar durch eine einen Geschwindigkeitsparameter, vorzugsweise einen Eingangsgeschwindigkeits-Parameter, der Fotopapierbahn registrierende Registriereinrichtung zur Ansteuerung und Betätigung der Steuerantriebseinheit entsprechend des registrierten Parameters. Vorzugsweise ist vorgesehen, daß auch ein Ansteuern der Ausgangsantriebseinheit durch die Registriereinrichtung möglich ist, insbesondere, damit sich die korrekte Papierspannung der Fotopapierbahn einstellt.The adjustment of the throughput path is advantageously carried out automatically, specifically by means of a registration device registering a speed parameter, preferably an input speed parameter, for actuating and actuating the control drive unit in accordance with the registered parameter. It is preferably provided that the output drive unit can also be controlled by the registration device, in particular so that the correct paper tension of the photo paper web is established.
Es kann bei·dieser Weiterbildung·der Vorrichtung auch ins Auge gefaßt werden, daß die Registriereinrichtung Geschwindigkeitsparameter beider Antriebseinheiten registriert und die Steuerantriebseinheit dann ansteuert und betätigt, wenn zwischen beiden Antriebseinheiten eine Geschwindigkeitsdifferenz vorliegt.In this further development of the device, it can also be envisaged that the registration device registers speed parameters of both drive units and then controls and actuates the control drive unit if there is a speed difference between the two drive units.
Eine Geschwindigkeitsänderung wird bei vorgeschaltetem Printer, bei Verwendung der erfindungsgemäßen Vorrichtung von diesem vorgegeben, so daß sich entsprechend zunächst die Eingangsgeschwindigkeit des Fotopapiers in der Entwicklungsvorrichtung ändert, während die Ausgangsgeschwindigkeit zunächst solange beibehalten wird, bis sich die Umlenkrollen auf die endgültige Position bewegt haben. Bei einem derartigen Verfahrensablauf kann damit eine Geschwindigkeitsdifferenz als geeigneter Geschwindigkeitsparameter zur Ansteuerung der Steuerantriebseinheit angesehen werden.A change in speed is predetermined by the printer connected upstream, when the device according to the invention is used, so that the input speed of the photo paper in the developing device changes accordingly, while the output speed is initially maintained until the deflection rollers have moved to the final position. In such a process sequence, a speed difference can thus be used as a suitable speed parameter for controlling the control drive unit be considered.
Nach einer nächsten Weiterbildung der erfindungsgemäßen Vorrichtung sind die verschiebbaren Umlenkrollen stufenlos, vorzugsweise auf einer Gleitführung, verschiebbar. Dies hat den Vorteil, daß der Durchlaufweg auch geringfügigen Geschwindigkeitsänderungen präzise angepaßt werden kann. Denkbar wäre auch eine nicht stufenlose Verschiebung, beispielsweise auf Rasterschienen oder ähnlichem.According to a next development of the device according to the invention, the displaceable deflection rollers can be displaced continuously, preferably on a sliding guide. This has the advantage that the throughput path can also be precisely adapted to slight changes in speed. It would also be conceivable not to move continuously, for example on grid rails or the like.
Egal welche Verschiebbarkeit vorgesehen ist, können als Steuerantriebseinheit an sich bekannte Antriebe, wie z.B. mit Ketten, Spindeln oder dergleichen eingesetzt werden.Regardless of which slidability is provided, drives known per se, such as e.g. can be used with chains, spindles or the like.
Zur Erreichung eines größeren Änderungsspielraumes des Durchlaufweges ist·nach einer Weiterbildung der Erfindung·vorgesehen, daß mehrere Umlenkrollen desselben Höhenniveaus verschiebbar sind und antriebsmäßig miteinander gekoppelt sind. Die antriebsmäßige Koppelung verbessert die Steuerbarkeit und läßt eine einzige Antriebseinheit genügen.In order to achieve a greater scope for changes in the throughput path, it is provided, according to a further development of the invention, that a plurality of deflection rollers of the same height level can be moved and are coupled to one another in terms of drive. The drive coupling improves controllability and allows a single drive unit to suffice.
Eine nächste Weiterbildung der Erfindung, für die auch selbständiger Schutz beansprucht wird, zeichnet sich dadurch aus, daß die Umlenkrollen in nur zwei Höhenniveaus angeordnet sind, daß alle Umlenkrollen eines der Höhenniveaus gekoppelt miteinander verschiebbar sind und daß eine Verschiebung dieser Rollen bis über das andere Höhenniveau der anderen Umlenkrollen hinaus möglich ist.A next development of the invention, for which independent protection is also claimed, is characterized in that the deflecting rollers are arranged in only two height levels, that all deflecting rollers of one of the height levels are coupled with one another and that a displacement of these rollers extends beyond the other height level the other pulleys is possible.
Bei dieser erfindungsgemäßen Weiterbildung der Entwicklungsvorrichtung wird der Vorteil erzielt, daß die Umlenkrollen in zwei Gruppen angeordnet sind, zwischen denen die Fotopapierbahn mäanderförmig hin- und herläuft und daß durch Verändern der Distanz dieser beiden Rollengruppen zueinander der Durchlaufweg der Fotopapierbahn sehr sauber und präzise bei größtmöglichem Veränderungsspielraum verändert werden kann.In this development of the development device according to the invention, the advantage is achieved that the deflecting rollers are arranged in two groups, between which the photo paper web runs back and forth in meandering fashion, and that by changing the distance between these two roller groups to one another, the path of travel of the photo paper web is very clean and precise with the greatest possible scope for change can be changed.
Zusätzlich hat diese Ausbildung den Vorteil, daß bei einem neuen Anfahren der Entwicklungsvorrichtung, vor dem zunächst ein Anfangsabschnitt einer neuen Fotopapierbahn eingeführt wird, dieses Einführen geschehen kann, während die verschiebbaren Rollen über das Höhenniveau der anderen Rollen hinausgeschoben sind, so daß der Anfangsabschnitt zwischen diesen Rollen hindurchgeschossen werden kann und sich bei Zurückfahren der beweglichen Umlenkrollen auf ihr ursprüngliches Niveau automatisch ein mäanderförmiger Verlauf über die Umlenkrollen der Fotopapierbahn ergibt. Die Entwicklungsvorrichtung kann dadurch mit sehr geringem Zeitverlust, beispielsweise nach einer Wartung, neu gestartet werden.In addition, this design has the advantage that when the developing device is started up anew, in front of which an initial section of a new photo paper web is first inserted, this insertion can take place while the displaceable rollers are pushed beyond the height level of the other rollers, so that the initial section between them Rolls can be shot through and when the movable deflection rollers are returned to their original level, a meandering course automatically results over the deflection rollers of the photo paper web. The development device can thus be restarted with very little loss of time, for example after maintenance.
Dieses Verschieben der verschiebbaren Umlenkrollen über das Höhenniveau der anderen Umlenkrollen hinaus ist bei einer Weiterbildung der Erfindung besonders einfach, die sich dadurch auszeichnet, daß jeweils die Umlenkrollen eines Höhenniveaus mechanisch zu einer kammartigen Rolleneinheit miteinander verbunden sind und daß die beiden Rolleneinheiten, sofern auf dasselbe Höhenniveau verschoben, miteinander kämmen.This displacement of the displaceable deflection rollers beyond the height level of the other deflection rollers is particularly simple in a development of the invention, which is characterized in that the deflection rollers of a height level are mechanically connected to each other to form a comb-like roller unit and that the two roller units, if provided to the same height level moved, comb together.
Vorzugsweise sind bei allen Ausführungen der erfindungsgemäßen Vorrichtung die verschiebbaren Umlenkrollen diejenigen, die dem tieferliegenden Höhenniveau angehören.In all embodiments of the device according to the invention, the displaceable deflection rollers are preferably those which belong to the lower level.

In Fig. 1 ist eine Vorrichtung zum Entwickeln von Papierbildern dargestellt. Die Papierbilder sind auf einer Fotopapierbahn 1 belichtet, die in Schlaufen mäanderförmig über Umlenkrollen 2a,2b durch die Entwicklungsvorrichtung läuft. Die Umlenkrollen 2a,2b sind in zwei Gruppen auf zwei Höhenniveaus angeordnet, wobei die Umlenkrollen 2a die untere Umlenkrollengruppe und die Umlenkrollen 2b die obere Umlenkrollengruppe bilden.1 shows an apparatus for developing paper images. The paper images are exposed on a
Die Fotopapierbahn 1 wird mittels einer Eingangsantriebseinheit 3 und einer Ausgangsantriebseinheit 4 durch die Entwicklungsvorrichtung über die Umlenkrollen 2a,2b transportiert.The
Die Umlenkrollen der unteren Umlenkrollengruppe und der oberen Umlenkrollengruppe sind jeweils mechanisch zu Rolleneinheiten miteinander verbunden. Die untere Rolleneinheit ist entlang von Gleitführungen 5 auf- und abbewegbar. Zur Bewegung dieser unteren Rolleneinheit ist eine Steuerantriebseinheit 6 vorgesehen, die antriebsmäßig über Ketten 7 mit der unteren Rolleneinheit gekoppelt ist. Zur Verbindung der unteren Rolleneinheit mit Ketten 7 sind Verbindungselemente 8 vorgesehen.The pulleys of the lower pulley group and the upper pulley group are mechanically connected to each other to form roller units. The lower roller unit can be moved up and down along slide guides 5. To move this lower roller unit, a
Die Steuerantriebseinheit 6 wird durch eine Registriereinrichtung 9 angesteuert und betätigt. Diese Registriereinrichtung 9 weist Sensoren 10 auf, die Geschwindigkeitsparameter von Eingangsantriebseinheit 3 und Ausgangsantriebseinheit 4 registrieren. Dabei kann eine Ansteuerung der Steuerantriebseinheit 6 beispielsweise erfolgen, wenn sich der Geschwindigkeitsparameter der Eingangsantriebseinheit 3 ändert oder wenn eine Differenz der Geschwindigkeitsparameter von Eingangs- und Ausgangsantriebseinheit auftritt.The
Die Gleitführungen 5 sind so lang ausgebildet, daß sie über das Höhenniveau der oberen Umlenkrollen 2b aufragen, so daß die unteren Umlenkrollen 2a bis über das Höhenniveau der oberen Umlenkrollen 2b heraufgefahren werden können. Diese oberste Stellung der unteren Umlenkrollen 2a ist gestrichelt mit den Bezugszahlen 2a′ für einige Umlenkrollen 2a angedeutet.The slide guides 5 are so long that they protrude above the level of the
In dieser angehobenen Stellung der unteren Umlenkrollen 2a′ kann zwischen diesen und den oberen Umlenkrollen 2b ein Anfangsabschnitt einer Fotopapierbahn 1 in einfacher Weise eingefädelt, nämlich hindurchgeschossen werden, wenn die Entwicklungsvorrichtung, beispielsweise nach einer Wartung, neu gestartet werden soll.In this raised position of the
