SU28774A1 - Device for automatic winding of the film on the bottom reel - Google Patents

Description

The inventor offers several options for adapting a film to an automatical film on the bottom reel. In one of them, the reel Rides freely on the rotating roller and is gripped by it, thanks to the rpefiKio between the surface of the roller and the hole in the reel hub, thereby eliminating the need for a spring, usually used to fix the reel on the roller. In the other, the axle of the roller is mounted on: dgprn: new bearings and used: -; center sleeve with a screw for adjusting the tension of the driving belt sa pulley. In the rest of the devices, springs and additional rollers are used to communicate the additional track.

In the drawing of FIG. 1 shows a general view of the device with a partial cut; FIG. 2, 3, 4, 6 and 7 - transverse sections of modified devices; FIG. 5 is a side view of the attachment; shown in FIG. four.

In the proposed device, the lower reel is mounted on the axis 2 (Fig. 1), the rotor rotates in the crown bearing; liner /. At one end of axis 2, the pulley 3 is fixed, and at the other end there is

separately manufactured and then connected with a splint 7 4 with a surface 6. which can be glued over to increase skin friction. A reel 5 is mounted loosely on the sleeve 4 with a large gap, and a stop 8 prevents it from moving along the sleeve 4. From the camera, the pulley 3 causes the axis 2 to rotate, which in turn causes the reel 5 to rotate, grabbing it by force of friction as the film reels on the reel, due to a gradual increase in the weight of the reel.

The first modification of the fixture described is that the axis 2 (FIG. 2) is mounted on ball bearings 9 in an eccentric bushing JO with a clamping screw 72 and a lubrication hole. To adjust the tension of the drive belt on the pulley 3, screw 72 is released, after which the eccentric sleeve 10 rotates slightly, removing or approaching the axis 2 relative to the other pulley. The bobbin is put on sleeve 4, and the latter on axle 2 and is detachable, which makes it possible to replace it if necessary with another.

In the fixture depicted in FIG. 3, an eccentric bushing 10 with a clamping screw 12 is also applied. leather pad 6. For the message of additional friction, a spring / 5 is installed on the axis 2 with a screw 16.

The second modification of the device is characterized in that the reel is mounted directly on axis 2 (FIGS. 4 and 5), the other end of which is provided with a thickening 2, on which pulley 3 is fitted, with a driving belt transmitting movement from pulley 20. Levers 23 and 24 supporting the pulleys 3 and 20 are rotatably mounted on the axle 22, and, in addition, are engaged by a spring 27, c; jyma to impart additional friction.

The third modification of the fixture is that the transfer of the movement 1 and from the pulley 3 to the axis 2 (Fig. 6) with the reel is accomplished by means of an additional roller 2 pressed against the reel to the thicker part 55 of the axis 2. At the same time, the thinned part of the roller 2 is installed in the non-moving bearing 34, and the bearing 36, axis 2 / is stated at the hinge 33. When winding, heal the bob ;; 1u, the weight of the reel increases, acting on axis 2 and causing the thickening of part 35 to poimen to the roller 32, which can be replaced with a pulley 3.

FIG. The /, represents a modification of the method described in FIG. 6, differing from it in that the lower bearing 34, supporting the additional roller 32, is fixedly mounted. The upper bearing 36 of the axis 2 is connected to the lower hinge not shown in the drawing, and to communicate the additional friction between the additional roller 32 and the thickened Part 35 of axis 2 to the upper movable bearing attached spring 37.
