Description

The invention relates to mechanical engineering and can be used when winding threadlike materials, such as wire, on coils of ferromagnetic materials.

The aim of the invention is to increase reliability and simplify the design.

The device comprises a housing 1, in which a shaft 3 supporting a coil 4 is mounted cantilever in a bearing support 2. A shaft 3 is connected to a drive (not shown) On the cantilever part of the shaft 3 is placed a means for fixing the coil having a fixed flange 5 and the possibility of limited rotation of the movable disk 6. Eccentrically to the shaft 3 on the movable disk 6, the finger 7 is rigidly fixed. s 9 which are placed on the ends of fingers 7.

magnets 13 with magnetic cores 14 and 15, but the reverse polarity is fixed on the movable disk 6. The flange 5 and the movable disk 6 are made of non-magnetic material, and the coil 4 is made of ferromagnetic material.

On the flange 5, additional magnets 16c can be placed by magnetic cores 17 and 18 of the same polarity as the magnets 13 of the movable disk biv of the same quantity. In addition, each of the additional magnets 16 is offset relative to the magnets 10 of the flange 5 by an angle equal to the angle of rotation of the movable disk 6 relative to the flange 5.

The device works as follows.

In the initial position, the movable disk 6 is mounted relative to the flange 5 so that the finger in the shaped groove 8 is in the extreme right position. The magnets 13 with the magnetic cores 14 and 15 of the movable disk 6 are located opposite the magnets 10 with the magnetic cores 11 and 12 of the flange 5. The magnetic flux coming out of the magnets 13 of the movable disk 6 is neutralized by the magnetic flux of the magnets 10 of the flange 5. Shaft 3 mounted on a bearing support 2 in case 1, braked.

The coil 4 is put on the shaft 3, aligning the hole 9 in the coil 4 with the finger 7, until it stops in the magnetic cores 14 and 15 of the magnets 13 of the movable disk 6. The coil 4 on the shaft 3 is turned against the direction of its rotation in this case, counterclockwise). The movement from the coil 4 is transmitted through the finger 7 to the movable disk 6. The mobile disk 6 together with the coil 4 and finger 7 rotates on the braked shaft 3 relative to the flange 5 until the finger 7 in the shaped groove 8 of the flange 5 takes the leftmost position. The magnets 13 of the movable disk 6 are displaced relative to the magnets 10 of the flange 5. And the magnetic fluxes coming out of the north poles of the magnets 13 of the movable disk 6 pass through the magnetic cores 14, the coil 4 and through the magnetic cores 15 close to the south poles of the magnets 13. The coil 4 attracts magnetic field to the movable disk 6.

The drive is turned on. The movement from the drive is transmitted to the shaft 3. From the shaft 3, the movement is transmitted through the flange 5 and the finger 7 to the movable disk 6 and the coil 4. The coil 4 rotates together with the shaft 3, the flange 5 and the movable disk 6 (clockwise). After the end of the technological operation, for example, winding the filamentous material on the coil 4, the drive is turned off, the shaft 3 is braked. The coil 4 is turned on the shaft 3 in the direction of its rotation (clockwise). The movement from the coil 4 is transmitted by means of the finger 7 to the movable disk 6. The moving disk 6 rotates on the braked shaft 3 until the finger 7 in the shaped groove 8 of the flange 5 is in the rightmost position. In this case, the magnets 13 of the movable disk 6 are located opposite the magnets 10 of the flange 5 and the magnetic flux of the magnets 13 of the movable disk 6 is neutralized by the magnetic flux of the magnets 10 of the flange 5. The coil 4 is removed from the shaft 3.

5 Next, the cycle of operation is repeated.

The placement of additional magnets 16 with magnetic cores 17 and 18 on the flange 5 does not affect the operation of the device. When attaching the coil 4, it also turns

0 against the direction of its rotation until the finger 7 in the shaped groove 8 of the flange 5 takes the far left position. The magnets 13 of the movable disk 6 are displaced relative to the magnets 10 of the flange 5 and

5 are located against additional magnets 16. And since the additional magnets 16 have the same polarity as the magnets 13 of the movable disk 6, the magnetic fluxes extending from the north poles of the additional magnets 16 of the flange 5 and the magnets 13 of the movable disk 6, pass t through the magnetic cores 17 and 14, the coil 4 and through the magnetic cores 15 and 18 are connected to the south poles of the additional magnets 16

5 flange 5 and magnets 13 of the movable disk 6, which increases only the force pressing the coil 4 to the movable disk 6.

The device prevents the coil from slipping on the shaft during winding.

0 due to its rigid connection with the shaft and to simplify the design of the device by reducing the number of parts and reducing the hinged joints.
