Description

one

The invention can be used in the electronics industry when creating special technological equipment for winding capacitor sections.

Devices for feeding ribbons to the mandrel are known, which comprise main and auxiliary sliders interconnected by a spring. A roller-eccentric clamp is mounted on the main slide, and two guide plates are mounted on the auxiliary slide. For braking the main slide, an emphasis is provided.

However, the known devices have insufficient reliability of refueling of thin electrified ribbons.

In order to increase the reliability of the device, the belt clamping mechanism is placed on the auxiliary slider, the sharirio guide plates are fixed on the main slide, 3 loading rollers are located on the free ends of the guide plates.

FIG. I shows a general view of the proposed device; in fig. 2 - technological scheme of the device operation.

The device for feeding the tapes to the mandrel consists of the main and auxiliary sliders 1 and 2, respectively, the spring 3 connecting the sliders, the tape clamping mechanism 4 and the guide plates 5 and 6, which are hinged on the axes x 7

Slider 1 and equipped with fixed rollers 8.

The device for feeding tapes to the mandrel contains tacl-Le stop 9, spring holders 10, springs 11 and 12, drive cams 13 and 14, knives 15 controlled by an electromagnet 16, mandrel 17, tape 18, tape roll 19, winding section 20, element 21 for welding section; a control electromagnet 22 and an eccentric 23 for accurately positioning the tensioned tape in the center of the mandrel.

Position 1 (Fig. 2) shows the time at which winding ends at section 20. After winding is completed, section 20 (position 1, fig. 2)

the knife 15 cuts the tape 18, while tightening the tape is shortened, its end slips in the rollers 8, and in the area from the rollers to the clamp 4 the tape loses a linear direction. After removing section 20 s

the mandrels, and the mandrel frees up space for the sliders by axial movement, the cams 13 and 14 move the slider 1 and through the spring 3 of the slider 2. When the rollers 8 fall below the axis of the mandrel, the auxiliary slider

2 reaches stop 9 and stops (position P, fig. 2).

Upon further movement of the main slide 1 downward, the tape 18 held by the fixed clip 4 also stops and

its end, clamped by rollers 8, continues

move down. The belt is tensioned and the ir linearity is applied. With the axial movement of the mandrel 17, the linearly tensioned tape 18 exactly fits into the front, spruce of the mandrel (position III, fig. 2) and after rotation, the latter will start to wind (position IV, fig. 2).

At positions V and VI, the operation of the device is shown when the cams move the sliders B to their original position.

Due to the additional tension of the tape in the process of its supply to the mandrel, the tape exactly fits into the slot of the mandrel, as a result, the filling of the tape occurs reliably.

4 P r with d m from and 3 about b with t e and and

A device for feeding mites to the mandrel, mainly winding coiled capacitors, comprising primary and secondary sliders interconnected by a spring, brake damper, clamping mechanism, guide plates and tensioning rollers, characterized in that, in order to improve the reliability of the ycTpotion, The belt clamping mechanism is located on the auxiliary creep, the guide plates are hinged on the main creep, and the roller rollers are located on the free ends of the guide nlastip.
