Description

The subject of the invention is an aggregate for the blueprint and dry appearance of the ovokokopiye of ammonia vapors, consisting of a capiroal device and a dry cell apparatus with an ammonia adjusting chamber.

The ammonia vapors, which are known for this purpose, do not offer the possibility of continuous reproduction of the drawings.

The basic feature of the present copying unit for auto copying and dry display of blueprints of the drawings is that in order to ensure the multiplication of the drawings, the input and output rollers of the dry appearance unit | Pr1I1 are driven by means of transfer from the output drive rollers of the copying machine.

FIG. 1 shows schematically a vertical longitudinal section of an assembly for 10 veterinary copy and dry appearance of copies of the drawings; in fig. 2 is a diagram of the power supply of the ammonia apparatus

The apparatus for the dry development of blueprints of the drawings consists of the following main components: an ammonia evacuation chamber, a power supply system of the ammonia apparatus and a suction chamber.

The ammonia chamber 1 is made of wood and represents a rectangular box, painted inside with heat-resistant Iraqi. At the beginning of the chamber, input rollers 2 are mounted, the upper of which can be raised and lowered to create the desired gap. This design of the rollers ensures free movement of the paper along the width of the machine, which is important when working on a conveyor belt. .The entrance rollers are designed to 1 feed the paper 3 from the light-copy machine 4 into the chamber of dry appearance. The rollers are driven by the Gall 5 chain from the output roller of the blueprint machine, which provides simultaneous operation of the dry appearance machine with the copying machine and the reproduction accuracy of the drawings.

At the end, the chambers are equipped with output rollers 6, the upper one of which is regulated by the same way as the input j; output rollers are fed to the infused paper on the cutting table 7.

Output rollers are driven by a Gaul circuit from the input rollers. For the possibility of making blueprints on the diazokalka, the input and output rollers have a bonded layer with a thickness of 20 -

25c For (Creation of sealing and elimination of unnecessary gaps in (input and output rollers along their entire length, protective steel Liiyaki 8 are installed. Bearings of rollers are fitted with glands to prevent penetration; k1NOVA ammonia vapors in the necks.

For the uniform penetration of ammonia vases to (light sensor in the ionic chamber, a duralumin perforated bottom 9 is installed along which the photosensitive paper moves, fed by input rollers 2.

Heaters 10 are located under the perforated bottom for heating the inlet and outlet rollers and heaters I / D placed in grooves serving to convert ammonia (ammonia water with 25% ammonia content) into its vapor.

MomjHOCTb of all heaters is 0.8 kW and provides 1 the required temperature IB of the chamber 70 - 80 °.

: A conical bottom with a drain pipe 12 is installed under the heaters for collecting and draining waste ammonia from the apparatus.

The apparatus of dry projection with ciHai6xvn system, which ensures the normal supply of the apparatus with ammonia, is continuous for 16 vehicles.

The dry supply ammonia power supply system is partially installed on the device itself and partly around it and consists of: 1) a reserve cylinder 13 mounted on a trolley and equipped with a stopcock 14; In this cylinder, ammonia (ammonia 25% water) is brought from the warehouse and 2) installed on the dry display apparatus of two ammonia tanks 15 equipped with control tubes 16 for supplying ammonia to the grooves with electric heaters 11.

The tank is filled with ammonia from the reserve cylinder 13 by the pentropulse pump 17, driven by the electric motor 18, by mounted communication from water pipes 19. To avoid overfilling, the tanks are equipped with level indicators 20. The centrifugal pump with a reserve cylinder is connected by a rubber nipple.

The dry art apparatus is connected to a wooden suction chamber 21 to prevent the vapor of ammonia from possibly spreading to the workroom.

A suction chamber is connected via air line 22 to exhaust ventilation. The degree of suction is regulated by the gate valve 23. The camera of the suction side is equipped with opening doors on each side, which allows free access to the connection system of electric heaters 10 and // the apparatus and driving devices.

The operation of the dry display apparatus of the drawings with ammonia vapors working in a stream with a photocopier consists of the following.

Over 10-15, MHH. Before the start of operation, the lamps 24 of the light-copying machine 4 and the electric heaters 10 and I are switched off for heating the rollers 2 and 5 and the evaporation channels of ammonia.

For 2-3 minutes Before starting work, the tube 16 for supplying ammonia IB includes a dry appearance apparatus. Then the drive of the photocopier is turned on, and thereby the device of the dry appearance.

In the usual way, a paper is passed through a photocopier, a photosensitive paper, with tracing paper over it. In a photocopier, an ekopoeing of the drawing on the photosensitive paper occurs.

After the light-sensitive paper with tracing paper has left the blue-copy machine, the tracing paper is removed and returned for re-splicing, and the end of the light-sensitive paper sheet that has come out is loaded into the input rollers 2 of the dry appearance apparatus. The passage through the tempering chamber, the paper protrudes and exits through the exit rollers 6, after which it is cut into separate drawings and folded.

The entire unit is serviced by a brigade consisting of three people: a paratrooper, a supplier (he also removes paper from an ototochuvstitelitelnoy and returns to ansharatchik for subsequent reproduction) and trimmer.
