Conventionally, electronic patterned circular knitting machines and electronic patterned round sock knitting machines have various electromagnetic needle selectors, but the jack that is the needle selection element can be single-stage type, multi-stage type, press type, or scoop type. The single-stage type is only a press type, which has a limit on needle selection speed, and high speed and high efficiency cannot be expected, and the multi-stage type includes a press type and a scoop type, but both have complicated structures. Due to the difficulty in manufacturing and assembly, and the difficulty in adjusting to maintain accuracy due to electromagnetic needle selection, the cost was enormous, and there were many difficulties in general use.

For example, the mount for the selector lever for needle selection and the mount for the electromagnetic needle selector are installed separately, and the electromagnetic coil is installed on each frame, and each frame must be individually installed on the mount.
There were many technical difficulties in the complexity of the structure, in the work and assembly, and in the adjustment of the connecting parts.

An object of the present invention is to provide an electromagnetic needle selector that eliminates the above-mentioned drawbacks. One end of the lever is formed with an inclined part for scooping up the jack, and the other end is formed with a stopper abutment part and a holder attachment part on both sides.A pair of stoppers are provided on both sides of the stopper abutment part, A holder having protrusions at both ends is fixed to the mounting part, a pair of permanent magnets are fixed to each of the protrusions at both ends of the holder, and electromagnetic coils are attached to both sides of each permanent magnet at a predetermined distance. The electromagnetic coils are arranged in a vertical line, and each electromagnetic coil is attached to a frame that is integrated into a vertical column on both the left and right sides. A pair of left and right frames that are integrated in a vertical column are all 1
Electronic patterned circular knitting machines and electronic patterned circular sock knitting machines that have extremely simple structures on individual mounting stands, are easy to manufacture and assemble, and require little adjustment and can be manufactured at low cost. The subject of the invention is an electromagnetic needle selector that can be used.

The configuration of the present invention will be explained in detail below with reference to the drawings.

As mentioned above, this electromagnetic needle selector is suitable for electronic patterned circular knitting machines and electronic patterned circular sock knitting machines where the jack, which is the needle selector of the knitting machine, is a multi-stage type and a scooping type. It has a configuration that

In FIG. 1, the knitting machine cylinder 1 rotates in the direction of the arrow around an axis (not shown). A groove 2 for knitting elements such as needles and jacks is provided on the outer periphery of the cylinder 1, and the needles and jacks (only the jack 3 in the figure) are slidably disposed within this groove 2. There is. Since the jack 3 has multistage butts, the butts 3-1 of the jack 3 are arranged so as to protrude from the outer periphery of the cylinder 1 at certain intervals.

The electromagnetic needle selector according to the present invention is as shown in FIG.
All the parts are configured to be attached to an L-shaped mounting base 5. That is, as shown in FIG.
The vertical part 5-1 of the mounting base 5 has a horizontal groove 5-1.
A plurality of grooves 2 are provided at equal intervals, and vertical grooves 5-3 are provided in the vertical direction to intersect with these horizontal grooves 5-2. (1st
(See figure) As shown in Figures 1 and 5, a plurality of levers 6 for needle selection are inserted into the horizontal groove 5-2, and the small hole 6-1, which is the fulcrum of the lever 6, is aligned with the vertical groove 5-3. At this position, insert the hard small-diameter pin 7 from above the vertical groove 5-3.
The lever 6 is arranged so as to be able to swing in an arc around this hard small diameter pin 7. The small diameter pin 7 is inserted into the vertical groove 5-3 by inserting the comb-shaped plate 8 into the plate 8.
It is fixed with screws 10 by a plate 9 that holds it down.

As shown in FIG. 1, one end of the lever 6 faces the outer peripheral surface of the knitting machine cylinder 1 and presents a rounded surface, and forms an inclined portion 6-2 for scooping up the butt 3-1 of the jack 3. Due to the action of an electromagnetic device, which will be described later, this inclined portion 6-2 swings in the direction of the arrow IN-OUT in FIG. 1 by the movement of the other end of the lever 6, and scoops up the butt 3-1 of the jack 3 It performs the function of whether or not. It is well known that when the jack 3 is scooped up, the needle (not shown) is placed on the knit line, and when it is not scooped up, the needle is placed on the welt line.

In FIG. 1, the other end of the lever 6 forms stopper abutting portions 6-3, 6-4, a holder attachment portion 6-5, and an extension portion 6-6. A pair of stoppers 11, 12 are provided with a gap between the stopper abutting portions 6-3, 6-4 of the lever 6, respectively.
is fixed to the vertical mounting surface 5-4 of the mounting base 5 with screws 13. These stoppers 11 and 12 are for allowing each of the plurality of levers 6 to obtain an accurately determined amount in the vertical movement range of IN←→OUT of the inclined portion 6-2 of the lever 6 that swings in a circular arc. It is possible to control the left and right panels with one panel each.

A holder 14 having protrusions at both ends is fitted into the holder attachment part 6-5 at the other end of the lever 6, and this part is caulked and fixed. (See FIG. 2) Permanent magnets 15,
16 is fixed with a strong adhesive via pipes 17 and 18 made of non-magnetic material.

An iron core 23 is placed opposite these permanent magnets 15 and 16 at a position with a certain gap between the swinging momentum of the lever 6 (the amount of movement of IN←→OUT in the inclined portion 6-2 of the lever 6). , 24

Further, the upper plate 31 holds the mounting base 5 and the shaft 29, and is fixed to the upper part of the mounting base 5 with screws 32. (See FIG. 5) The structure of the electromagnetic needle selector according to the present invention has been described above, and the operating state will be explained below.

When a handle signal is energized to the electromagnetic coils 19 and 20 in response to a command from an electronic handle drive device (not shown), one of the permanent magnets fixed to the lever 6 is attracted, and the other is repelled. A magnetic circuit is generated, and a magnetic circuit opposite thereto is generated, and the lever 6 is caused to undergo an arcuate swinging movement about the hard small-diameter pin 7 in response to the respective signals. The inclined portion 6-2 at one end of the lever 6 operates in the direction of IN←→OUT with respect to the outer peripheral surface of the cylinder 1 as described above, but in order to obtain a constant stroke with respect to the butt 3-1 of the jack 3, The positions of the abutting portions 6-3 and 6-6 are precisely controlled by stoppers 11 and 12.

Therefore, when the lever 6 swings in an arc, the lever 6
For permanent magnets 5 and 6, electromagnetic coils 19 and 20
Since the coils 19 and 20 are held by the frames 21 and 22 which are integrated in a column, there is no need for any adjustment of the coils 19 and 20, and the stoppers 11 and 12 are also integrated into a column, so this also applies. 1 There is no need for individual adjustment.

As mentioned above, multiple levers that can swing around a hard small-diameter pin as a fulcrum, a pair of left and right stoppers, and a pair of left and right frames with electromagnetic coils arranged in tandem are all assembled into a single mounting base for parts processing and assembly. This is an electromagnetic needle selector that can be manufactured easily and at a very low cost without requiring individual adjustment of the stopper or electromagnetic coil, by simply changing the R surface of the sloped part of the lever. So, electronic patterned circular knitting machine,
It can be applied to electronic patterned round sock knitting machines and other various knitting machines without going beyond the scope of the claims.
