SU394477A1 - DEVICE FOR SELECTION OF NEEDLES ON A KNITTING MACHINE - Google Patents

Description

Isob; reteiiie refers to the field of knitting machinery, in particular to the design of the device for the selection of needles in the hall machines.

FROM) The device for selecting a “head in a caulking machine”, containing a wedge of selection wedges, see-winding in a lock, spring elements for lifting needles located across the needle rods and cantilevered under them in the needle bed, the spring elements have the ability to interact with the base of the needles and is electrically connected with the control system.

In order to increase the reliability of selection in the proposed device, the control system contains an electromagnet, and the free ends of the spring elements are installed with the ability to move in the air gap between the poles of the electromagnet.

FIG. 1 shows the proposed device in section, smeared on the cylinder of the circular machine; in fig. 2 — loop-forming systems containing wedges; in fig. 3 - composite electromagnet.

In the groove of the cylinder / formed by the pins 2, tongue needles 3 are installed under each of which the pick-up spring elements 4 are mounted, with one end

5 rigidly fixed in the sector 6 of the cylinder 1, and the other free end 7 have the ability to interact with the base 8 of the rod 9 needle 3.

. Under the needles 3, electromagnets 10 are interconnected, which cooperate with cantilever spring-collecting elements 4 that are cantilever-mounted in a needle bed (cylinder /). Spring elements 4 are located across

rods 9 needles 3.

The movement of the needles takes place in the moving kulirny and enclosing wedges // and 12 through interaction with the helix 13 and 3 of the gl that slide through the channels 14 or 13.

The lifting of the pick spring elements 4 is carried out by the selection wedge 16.

The output of the elements 4 to the electromagnets 10 is produced by the selection wedge 17.

The electromagnet 10 is made of composite, m, one part of which is made in the Vide. Two cores 18 and 19, and the other part 20 has a U-shape.

The wedges 16 and 17 n of the electromagnet 10 form a gap a in which the selection of the spring elements 4 is made. Behind the electromagnets 10, in the direction of the needles selection, are mounted permanent magnets 21 for holding the selection spring elements 4.

The spring element 4, the interaction of the CIWAY end 7 with the wedge 17 is deflected downwards and is led to the pole of the electromagnet 10, controlled in accordance with the report drawing.

If it is necessary to turn the needle out of work, then the end 7 of the elbMent 4 is first held by the elaptomatnit 10, and then constant, m. MaipHHTOM 21 dO, iOp, the spring element will not pass the distance a. 71, the next element 4 goes from zero to 10 to 21 and presses KOHIHOM 7 to the bottom edge of the wedge 16. Next, the neotoranny Elements 4, reaching the end of the wedge 16, fold (I1) and the bottom of the 7 nod dels; 17, are lowered and inserted to the electromagnet 10 by the next non-electric system for new selection of the pattern. The needles 3, which correspond to the unselected power lines 4, pass through channel 1.5 and remain at the level of the baffle plate, and exit to the thread penetration zone.

When the needle 3 must be connected to one another, the impulse Wi of the electromagnet is applied to the unraw, the impulse is applied, and the end 7 of the spring element 4 is not held (the electrO magnet 10 pushes upwards through the gap and into the channel between wedges mi 16 and 17 and nri | Lift are affected by paspopia 8th grade) 9 needles 3, but it is lifted by it and} aaravl, n tku 13 on the closing wedge 12.

The ends of 7 elements 4, lifted by Clii 16 to a small height, necessary to enter 13 into channel 14, first due to elastic forces, and then under the effective wedge / 7,

they go down and are fed to the electromagnet 10 for the next selection in the next loop-forming system.

The lowering and selection of the primary components

4 occurs when the needles are lifted for closing and for dividing them with a wedge

10, which reduces the length of

in stinging systems.

At the time of sampling, when the needle 3 must be raised to the order; 1 moment, the end 7 of the springing element 4 nrite bends to the upper zero of the electromagnet 10.

The time of movement of the spring element 4 is determined by the elastic forces of the e.

The position of the springs; its element 4, shown by dotted lines on the phi 1 1, corresponds to its position at the maximum height of the wedge 16 (ft 2).

PREPARATION AND CONTRIBUTION {CETENI

A device for taking needles in the hall of the Machine, containing a group of selection wedges, wedged in the lock, spring elements. Needle lifting elements located across the needle rods and cantilever-mounted with needle bases, while the spring elements have the ability to interact with the bases of the needles. electrically connected with the control system, characterized in that, in order to increase the reliability of the selection, the system of unlearning soda;) an electromagnet is attached, and the free ends of the external elements are installed with the possibility of geni in the air gap between the poles of electromagnets.
