Device for controlling the flow of photographic material in one with an automatic one Development system for cooperating electronic light setting device

The invention relates to a device for controlling the photo material duration in an electronic light set device that works together with an automatic development system,

Computer-controlled electronic photocomposing systems that work according to the raster process can set several hundred characters per second. However, there is a desire to have the exposed photographic material developed and dried as quickly as possible after setting. This is particularly necessary if the typesetting material is to be used first as follows: Proofreading. Proofs are preferably au * paper, which with a suitable Γύί · Sohnellentwlüklung photosensitive layer provided 1st "Bas photographic paper is in the Liohtsetsanlage duron a · automatically operating Bntwioklungsftnlmg" passed · Bort running; * By swel baths, the activator and the stabilizer

bath, further through nine drying chamber and then leaves the Iiiohtsetzgerät for wide use. The time between exposure and drying is about a minute.

The operation of setting with the light setting device and the development system must be viewed as acidic, at least for periods of time during which a whole roll of material is set · The strip length of a roll is about 100 B.

The generation speed of the exposed and developed photographic material in the setting device is very low. Everything depends on the width of the lines and the degree of font used. The narrower the gap and the more the larger the font size, the faster the image will be Stripes generated. The generation is correspondingly slower with wide lines and small fonts. Other factors bring further irregularities with them. Ss can e.g. small There are breaks that are caused by the computer program. The setting system can even come to a complete standstill at times come, e.g. if photo material has to be reinserted, or a control hole strip or a control magnetic tape must be changed must * On the other hand, intermediate empty prefixes act Accelerating in the flags. The rate of generation of exposed material is therefore irregular within wide limits.

The development device, on the other hand, requires a constant throughput speed. The duration of the stay in the actuator fluid depends on the blackening of the grape egg ovary images. Deviations from a certain throughput speed of

which in turn is a "specific one that is necessary for the printing process Blackening is not allowed. Above all, however, the development device must not be stopped as long as it is in lim There is still photographic material, as the material would become unusable.

The aim of the invention now allows it, despite these very different things Operating conditions ensure that both devices work together » possible. This is done in the way that the visual means are provided which have the effect that the setting tool is stopped when the photographic material «wipes the output of the setting tool and the Entrance of the Bntwioklungsanlage that the photographic material is jammed is cut through when it is stretched and that the photographic material is prevented from entering the de-airing system, as long as a previously cut piece of material has not fully entered the development system.

According to the embodiment of the invention, a cutting device arranged between the output of the light setting device and the input of the development system and an elongated guide path for the photographic material are provided, as well as a contact that responds to the accumulation of the photographic material in this guide path A device which, when actuated, causes the clock generation in the light set device and the acceptance of further set information to be suppressed, and a further contact device which responds to the pulling of the photographic material * in the guideway and whose actuation accelerates the transport of the photographic material by a certain length is triggered, furthermore the cutting device is arranged after completion of this Traneport, Aa * Photomaterial forchsusolni «*«! en, _Dftr

As the set progresses, there will be more photo material between the knives of the cutting device 13 pushed back into the guide track 14. The breaks between the individual film transports depend on the width of the line and the size of the sohrift from, the lengths of the film transports depend τοη the font size and the Durohsohuss off. So the film transport is great irregular · Is there so much photo material in the guide spell 14 run in that its beginning is the inlet gap of the developing device β has reached 16, it is seized by the Hollen 15 "By At this moment, the photo material must be passed through evenly be maintained by the development plant 16 This must also be done if, as already described, the photobtrelfen from the set device is slower or faster as the pass-through possibility in the development plant amounts to·

It is also assumed that the developing device 16 works more slowly when the photographic material is delivered.

more and more ε η to the left wall and is finally geetauto The photosensitive material is so stiff that it it exerts pressure in the direction of oils left side wall. The contact 20 is actuated by this dynamic pressure. This contact is transmitted to the central control unit 2 via the line 21 and its clock generation is interrupted. The acceptance of further information from the input device 4 is prevented via the line 5. The set operation is suspended as long as contact 20 is closed. There is no sweep of the road and no further photographic material is transported. The developing device 16, however, continues to work and sees photographic material from the guide track 14 during this time. The jam of the photo strip subsides. After a slight delay, contact 20 opens again and enables the network system. The setting operation continues. This operating case does not present any difficulties because the set device can be held at any time.

In the opposite case, however, if the speed of generation of exposed photographic material is less than the speed of development des.Material is, the photo strip in the guideway 14 is kitser «It is stretched and snuggled on the right side wall of the guideway. But before this happens, the contact 22 is actuated. It gives a signal to the central control unit 2 via line 23. Contact 22 is actuated before the photo material is stretched too much. Therefore, the tool is given enough time to the line which it had begun to put, to put at the end of Ju " The command which then comes next to input device 4, which

Therefore, the practice during the chase operation are omitted :? the line 5 to the input device 4 continuously given command order for the time being. At the same time, however, a signal goes over the line 17 to the control unit 18. The first sequence of this is released over the line 19 to drive the transport rollers 12, which move the photographic material on by a checked piece. The length of this piece is equal to a certain number of length quanta and so large that the area of the photographic material just exposed is transported a few centimeters beyond the cutting parts. The cutting device 13 is then actuated via the line 24 and the strip is cut through. The cut strip can now run unhindered through the guide track 14 into the development system 16.

In the case at hand that the setting device works slower than the developing device, it would be useful that after the setting of one or two layers from the computer a cutting command is given · The child parts are fed by empty feeds placed in the photo strip so that each column is at the top and bottom has enough white space.

thus determined by the distance between the rollers 15 and 31 and is about 30 cm.

The photo strip is now pushed by the rollers 31 into the Irook chamber 32. Sr slides through the roller grate 33 and is further steered between the rollers 35 by the Ualenkblech 34-. These are also tri-rollers and give the photo strip the same transport speed as the Bollen 15 and 31 · The Bollen 35 transport the completely developed and dried photo strip out of the system into a collecting device from which the set material is removed. In the drying chamber 32, the heating resistors 36 are arranged on both sides of the egg grate 33, which dry the photo strips by radiant heat. The fan 37 supplies a stream of air which removes the vapors emerging from the photographic material through the opening 33.

In the following further operations, in addition to the task of checking whether the photographic material is jammed or sucked, the guide track 14 must also fulfill a storage or buffer function. If, for certain reasons, the photographic material is not to be cut through, although the setting speed is higher than the throughput speed in the winding system, the photographic material must be given a feed advance by computer commands after each setting of a column, by means of which the difference in speed is compensated. The Leervor- ä schubgesehwindigiceit is about 12 m ero Hinute always greater than the EntwUcläungs speed which is approximately 4 meters per Hinute.
