Изобретение относитс к устройствам дл обработки экспонированных фотоматериалов.The invention relates to devices for processing exposed photographic materials.

Известны автоматы дл обработки экспонированной цветной фотобумаги, содерн ащие поворотную площадку с емкост ми дл рабочих растворов и воды и реле времени в виде установленного на площадке распределительного барабана 1.Machines are known for processing the exposed color photographic paper, comprising a rotary platform with containers for working solutions and water and a time relay in the form of a distribution drum 1 installed on the platform.

Однако такие устройства имеют сложную конструкцию.However, such devices have a complex structure.

Известны также устройства барабанного типа ДЛЯ обработки и сушки фотоматериалов, содержащие расположенные по кругу емкости с рабочим раствором и водой, основание с вертикальной стойкой и размещенными на ней в нижней и верхней част х соответственно шестерней привода и кронштейном дл механизма возвратно-поступательного перемещени держател с фотоматериалом, установленного с возможностью вращени , сушильный и программный узлы 2.Also known are drum-type devices for processing and drying photographic materials containing circular containers with working solution and water, a base with a vertical stand and placed on it in the lower and upper parts respectively of the drive gear and bracket for the reciprocating mechanism of the holder with the photographic material rotatably mounted, dryer and program units 2.

Недостатками известных устройств вл ютс СЛОЖНОСТЬ и невысока надежность.The disadvantages of the known devices are COMPLEXITY and low reliability.

С целью повышени надежности работы, в устройство по изобретению введена платформа с роликами, контактирующими с основанием , а механизм возвратно-поступательного перемещени держател выполнен в виде зубчатой рейки с выключателем программного узла, контактирующим с упором емкости;In order to increase the reliability of operation, a platform with rollers in contact with the base is introduced into the device according to the invention, and the mechanism of reciprocating movement of the holder is made in the form of a toothed rack with a switch of the program node in contact with the capacity stop;

держатель фотоматериала представл ет собой камеру с жалюзи в ее днище.The photo holder is a camera with blinds in its bottom.

На фиг. 1 показано предлагаемое устройство , общий вид; на фиг. 2 - то же, разрез А-А на фиг. 1.FIG. 1 shows the proposed device, a general view; in fig. 2 is the same, section A-A in FIG. one.

Устройство состоит из основани 1, вертикальной стойки 2, платформы 3 с роликами 4, емкостей 5, сушильного узла 6, емкости 7 дл воды со СЛИВНЫМ и подвод щим трубопроводами , кронштейна 8, механизма возвратно-поступательного перемещени в виде зубчатой рейки 9 с приводом 10, держател 11 фотоматериалов с приводом 12, камеры 13 с жалюзи в ее днище, привода 14 дл платформы 3,The device consists of a base 1, a vertical rack 2, a platform 3 with rollers 4, containers 5, a drying unit 6, a water tank 7 for DRAIN and supply pipes, a bracket 8, a reciprocating mechanism in the form of a toothed rack 9 with a drive 10 , a holder of 11 photographic materials with a drive 12, a camera 13 with louvers at its bottom, a drive 14 for platform 3,

программного узла 15 с блоком исполнительных реле и реле времени, выключател 16, упоров 17 против каладой емкости 5, сушильного узла 6 и вырезов между ними, выключател 18 на кронштейне 8, выключател 19 наsoftware node 15 with a block of actuating relays and a time relay, switch 16, stops 17 against the capacity 5, drying node 6 and cuts between them, switch 18 on the bracket 8, switch 19 on

зубчатой рейке 9, выключател 20 на стенке сушильного узла 6.gear rail 9, switch 20 on the wall of the drying unit 6.

Работает устройство следующим образом. В темном помещении заправл ют фотоматериал в кассету и заключают в KaAiepy 13.The device works as follows. In a dark room, photo material is loaded into a cassette and placed in KaAiepy 13.

Claims

All further operations are performed in the light. The containers 5 are filled with working solutions of chemicals, then the water supply valve is opened into the tank 7. The chamber 13 is fixed on the gear rail 9 and the drive 10 of the gear rail 9 is turned on. The chamber 13 with the cassette in it is lowered into the tank 5. At the same time, they are filled in the form of floats the blinds of the bottom of the chamber 13 are opened and the working solution penetrates the chamber, forcing the air out of it through labyrinth holes in its upper part. When the rack 9 is lowered so that the switch 19 comes into contact with the wall of the container 5, the drive 10 is turned off and the drive 12 of the rotation of the camera 13 with the cassette is turned on. With an exposure equal to the time taken to produce photographic material, another time relay of the software node 15 turns off the drive 12 of the holder 11 and turns on the drive 10 of the rack 9 on the rise. At the end of the reverse travel of the toothed rack 9, the actuator 10 is turned off by the switch 18 and the drive 14 of the platform 3 is simultaneously turned on. The latter is turned by an angle corresponding to the distance between two adjacent stops 17, coming into contact with the next stop, the switch 16 turns off the drive 14 of the platform 3. At By turning the platform 3, the solution tank 5 is brought out from under the rack 9. Then the drive 10 is turned on, the rack rail 9 lowers the chamber 13 with the photo material into the tank 7 up to the stop in the wall of the bottom switch 19, then the gear 10 drive eyki 9 is turned off, the actuator 12 is turned on the holder 11 and materials enclosed in compartment 13, washed. With a time delay equal to the duration of the flushing of photographic materials, the actuator 12 is turned off and the actuator 10 is turned on to raise the toothed rack 9. When the latter reaches the extreme upper position, its actuator 10 is turned off by the switch 18 and the actuator 14 of the platform 3 is simultaneously turned on; the latter rotates and inserts the following element 5 10 15 20 25 30 35 40 under bone rack 9 with bone 5i filled with fixer solution; The operations are repeated in each tank 5y until the processing of the photographic material according to a given technology is completed. After that, at the next rotation of the platform 3, the drying unit 6 is under the holder 11 of the chamber 13, the heating element and the fan are turned on by the switch 20 and the processed photographic material is dried by hot air flows into the chamber 13 through the blinds. Claims 1. A drum-type device for processing and drying photographic materials comprising containers with working solution and water arranged in a circle, a base with a vertical stand and placed on it in the lower and upper parts respectively of the drive gear and bracket for the reciprocating mechanism of the holder rotatably mounted photographic material, a drying and a software assembly, characterized in that, in order to improve the reliability of the device, a platform with a ro ikami in contact with the base, and the mechanism of the reciprocating movement of the holder is designed as a toothed rack with software at the host switch, contacting abutment container. : 2. A device according to claim 1, characterized in that the holder of the photographic material is made in the form of a camera with blinds in its bottom.
