Description

one

The invention relates to the field of knitting machine building, in particular, to thread feeding devices for circular machines.

A thread-feeding ring of a multi-system circular-caster automaton is known; it is equipped with groups of thread guides according to the number of loop-forming systems and their control mechanisms, each of which is made in the form of a drum and interacts with a brake and with a lever-ratchet mechanism kinematically connected with the distribution drum of the machine.

The proposed threading ring differs from the well-known in that in order to reduce its dimensions and increase the reliability of operation, the group of thread guides for each pair of loop-forming systems and the corresponding control gear drums are mounted on axes mounted on a common support connected to the ring base and both sides of her.

The thread guides of the paired groups are made in the form of flat levers parallel to the diameter of the needle cylinder, passing inside the angle between the threading points of the corresponding loop-forming systems.

FIG. 1 shows a filament ring, a plan view; in fig. 2 shows a section along A-A “and FIG. 1 and 3; in fig. 3 is a section along BB in FIG. 2 and 4; in fig. 4 - section along

B-B in FIG. 3; in fig. 5 is a section along G ‑ Y in FIG. four.

The thread-feeding ring of the multi-system circular-jug automaton is equipped with groups of yarn guides / and 2 (see Fig. 1-4) according to the number of loop-forming systems and mechanisms controlling them.

Groups of thread guides, made in the form of flat levers, each pair of loop-forming

The systems are mounted on an axis 3 fixed on a support, 4, which is movably mounted on an axis 5 of a fork 6 mounted on the skeleton 7 of a thread-bearing ring. The thread guides / and 2 are equipped with springs 8, pressing

them to the adjusting screws 9.

Axis 5 is held against axial displacement by nuts 10 and 11.

On the support 4 is also mounted roller 12 (see Fig. 1, 2, 5) fixed by rotation

and axial shear screw 13. On this roller are free to sit the drums 14 and 15, equipped with rims 16 and 17, in which the grooves typed in toothed racks 18 and 19 are milled. The lath teeth can be cut down in accordance with the program for switching thread guides / and 2 and contact with the shanks of the yarn feeders. The drums 14 and 15 interact with the brake discs 20 and 21, kept from rotating with them with the pin 22,

pressed into the support 4.

Ratchets 23 and 24 (see Figs. 4, 5), interacting with dogs 25 and 26, mounted on axles 27 and 28 of levers 29 and 30, are connected with the same drums. Dogs are pressed to ratchets 23 and 24 by springs 31 (see Fig. 4).

Each of the levers 29 (30) has a groove 32 (33), which includes a roller 34 (35) mounted on a rotary lever 36 (37). The levers 36 and 37 freely sit in the grooves of the nuts 10 and 11 and are connected by cables 38 and 39 with the distribution drum of the machine (not shown). The slats 40 and 41 of cables 38 and 39 (see FIGS. 2-4) using bushings 42 and 43, nuts 44, 45, and studs 46 are fixed on the shank of support 4. Springs 47 connect levers 5 and 57 to support 4, and the springs 48 and 49, placed in the grooves of these levers, press the support 4 to the stud 50, which is in contact with the face cam 51, made in the form of a ring mounted in the bore of the skeleton 7 (see Fig. 4).

A support 52 with eyes for filaments 53, which are supplied by thread guides / (2) to the needles 54 of the needle cylinder (see Figs. 1 and 2), is also fixed on the support 4.

The mechanism of the thread-bearing ring works as follows.

When switching the thread guides / or 2 with the cable 38 (39), the lever 36 (37) is turned by the signal of the distribution drum, which with the roller 34 (35) acts on the lever 29 (30). Dog 25 (26) lever 29 (30) turn the ratchet 23 (24), and with it

and the drum 14 (15) one step, untrodden teeth of the rail 18 (19) off the thread guides.

If it is necessary to simultaneously turn off all the thread guides / and 2, for example, when turning off the corresponding pair of loop-forming systems, turn the end cam 5.1 and the pin 50 raise the support 4.
