    The device includes a canal having a narrowing entry and a widening outlet, separated by the poles of a pair of opposing electromagnets, and in which selective means, or selectors, are shifted. Two substantially identical, geometrically and magnetically symmetrical selector stations are provided. The entry and the outlet of the canal include a magnetic adherance system, functioning alternately as a stabilizer and as an amplifier of movement, following the direction of the device shifting in relation to the selectors to be selected.

    2. The pop. 1 mechanism, I distinguish between u and with the fact that each electromagnet has a P-shaped core with two series-connected coils.
    3. The mechanism according to claim 1 is also distinguished by the fact that, in order to simplify its assembly while maintaining the accuracy of the assembly, in contact planes of non-magnetic gaskets and pole pieces, as well as non-magnetic gaskets and supports are made
    grooves, in each of which is placed on one deformable cylindrical element.

    4, The mechanism according to p .1, which is based on the fact that, in order to simplify its assembly while preserving the 1st assembly, the magnetic systems and the base plate have alignment pins, and in the support are made from: the milestones in which the installation pins are placed.
    The invention relates to a knitwear industry, and more specifically to electromagnetic needle selection mechanisms for hall machines. An electromechanical device for withdrawing needles for dormitory machines is known, which contains a base plate with a support on which two identical magnetic systems are installed, forming a channel narrowing in the middle part for the passage of acupuncture elements, the lower part of which is formed by pole tips of permanent magnets, and the tapering middle part is with pole tips of electromagnets, each magnetic system having non-magnetic gaskets installed between the lateral sides of the pole tips, and also between olyusnymi lugs and the support l. The disadvantage of this device is the low reliability of the selection of needles due to the non-uniformity of the magnetic field in the channel for the passage of the acupuncture elements. The purpose of the invention is to increase the reliability of needle selection. The goal is to achieve that in an electromagnetic mechanism containing a base plate with a support on which two identical magnetic systems are installed, forming a channel narrowing in the middle part for the passage of acupuncture elements, the lower part of which is formed by pole tips of permanent magnets, and narrowing with media: In some cases, the pole tips of electromagnets, each magnetic system having non-magnetic gaskets installed between the lateral sides of 1 pole tips, and between with the pole tips and the support, the upper part of the channel for the passage of the needle-removing elements is formed by the pole tips of the additional permanent magnets, while the permanent magnets of each magnetic system are located symmetrically with respect to the plane passing through the center of the needle ridge perpendicular to its longitudinal axis. In addition, each electromagnet has a U-shaped core with two series-connected coils. At the same time, grooves are made in the contiguous planes of non-magnetic spacers and pole pieces, as well as non-magnetic spacers and supports, each of which contains one deformable cylindrical element. Moreover, the magnetic systems and the base plate have installation pins, and in the support holes are made in which the installation pins are placed. FIG. 1 shows an electromagnetic mechanism for picking needles, a plan view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 2. The mechanism consists of a base plate 1 on which the supports 2 are located with two identical magnetic systems forming a channel narrowing in the middle part for the passage of the acupuncture elements h. The lower part 4 and 5 of the channel is formed by pole tips 6 of the permanent magnets 7, the upper part 8 and 9 of the channel is also formed by the pole tips 6 additional magnets 7. The tapering middle part cana. Nala is formed by the floor (with the electrical tips of 10 and 11 electromagnets 12 and 13 ... Each magnetic system, including /) a permanent magnet 7 and an electromagnet 12 and 13, is isolated from the support 2 by a non-magnetic gasket 14 (Fig. 2). The gaskets 14 are insulated from one another by permanent magnets and electromagnets. (The electromagnets 12 and 13 have a P-o different cores with two coils in series 15. The magnetic systems and the plate 1 have respectively mounting pins 16 to 19, which are joined by holes 20 and 21, made in non-magnetic gaskets 14. For fastening magnetic systems are covers 22 with latches 23. In the contiguous planes of non-magnetic spacers and pole tips, as well as non-magnetic spacers and supports 2, V-shaped pairs 24 are made, in which deformable cylindrical elements are placed, for example water 25. Pole tips 6 and 10 (11) are separated from each other by means of a spacer element 26. Pole end 6 has an outlet part 27 (Fig. 3). In non-magnetic gaskets 14 holes 28 are made (Fig. 4) for the passage of pins 16. The electromagnetic needle selection mechanism works as follows: The movement of the needle-removing elements 3 is carried out from a control unit (not shown) by applying voltage to the coils 15 of electromagnets 12 and 13. The reliability of the operation of the electromagnetic mechanism largely determines the uniformity of the magnetic field. in the canopy for the passage of acupuncture lementozh.

    The new part of the 8th and 9th channels, as well as the symmetrical arrangement of all the magnets, ensure the uniformity of the magnetic field throughout the channel. In addition, the uniformity of the magnetic field depends on the build quality of the electromagnetic mechanism. For this purpose, grooves 24 are provided in the mechanism, in which deformable wires 25 are placed. The wire diameter 25 is chosen so that when the wire is deformed by clamping elements of the magnetic system with a bolt 23, the gaps formed by the slots 24 completely fill the gaps. It is strictly necessary to orient the details of magnetic systems, one relative to another. For ease of assembly while maintaining the accuracy of the assembly, pins 16,18,19 and 17 are provided in the mechanism. Due to the holes 21 and 20 made in the gaskets 14, the pins can be easily installed in them, allowing you to orient parts of magnetic systems without additional post-assembly adjustment . The implementation of electromagnets 12 and 13 with U-shaped cores having coils 15 connected in series, makes it possible to reduce the inductance of the resistance of the magnets and thus reduce their energy consumption while maintaining the required inductance. magnetic fields. The economic effect from the use of the proposed device is determined by the high reliability of the selection of needle-picking elements, as well as the ease of assembly and adjustment of the electromagnetic needle selection mechanism.
