SU14847A1 - Device for winding films before processing or drying them - Google Patents

Description

The proposed device is intended for the development of films and films in coiled form. In order to eliminate the adjoining 1 and to each other surfaces of the film when winding it, two disks are used with retractable, spring-loaded and spirally arranged buttons, which are equipped with tail rods and are pushed by moving n.

In FIG. 1 is a perspective view of a device; FIG. 2 - the same, vertical section; FIG. 3 is the same side view; FIG. 4-view of a single disk from the inside of the device; FIG. 5 is a sectional view of a portion of a disc with a protruding tail button stem; and FIG. 6 is the same, with a protruding button head.

On axis 2 there are fixed disks 1, 1 on which there are helically located recesses with openings for buttons 8, fitted with tail rods 9, the ends of which protrude beyond the surface of the disks (Fig. 5). The recesses for the buttons in the discs are provided with internal undercuts T (Fig. 5), and the buttons have curved flat springs 10 (Figs 5 and 6), the bending profile of which corresponds to the cross-sectional profile of the recesses 1. On axis 2, rotating

in bearings 2, 2, gears 4, 4 (figs. 2 and 3) are arranged with gear racks 6,6, which are pressed to wheels 4, 4 by rollers 5, 5. A set of rails 6, 6 is rigidly connected to the feet 7, 7 arc 3, which are adjacent to the surfaces of the disks 1, 1.

The end of the film 11 (Fig. 4) is fixed on the axis 2 between the disks 1, 1, which are driven into rotation, with heels 7, 7 of the arc 3 under the action of the gear wheels 4, 4 rotating with the axis 2, and rails 6, 6 receive vertical movement. As it moves, the pins 7, 7 meet the tail rods 9, press them and thereby push the buttons 8 into the gap between the disks 1, 1, on which heads the film P. is wound. The buttons 8 are held in the extended position by means of springs 10, which with their bends enter the undercuts of the V grooves for the buttons in the disks 1.1. After that, the film 11 thus wound together with the device is placed in a reagent vessel, processed and dried.

The subject of the patent.

A device for winding films before processing or in actual form, characterized by the use of two disks 1, 1 with extendable, spring and spiral buttons arranged 8, "equipped with tail rods 9,

employees to push, by means of moving n 7, 7, buttons 8 into the gap between the discs 1,1 with the aim of winding the film 11 on them.
