SU107021A1 - Adaptation to the round billet, for example, a self-fusing machine for forcing a thread - Google Patents

Description

The proposed device for a round billet, for example, a self-wringing machine for forcing the yarn, made in the form of a pair of drive gears for feeding the yarn, a thread loop, suspended on the loop of the yarn, a mechanism for turning off the gear and the gear of the yarn and the mechanism for turning off the machine when it breaks the thread compared to the well-known device of this type, it improves the quality of the produced stockings by reducing the defects of the single length and the zebrainess of the stockings, as well as by reducing the percentage enta breakdowns.

In the hysteary attachment for filing the thread is made of an elastic material, for example, vinyl plastic.

The device is equipped with a rocker arm, connected by a pull to the lock of the machine's deactivation lever and a driving ring with studs of the torque lever.

The yoke is made to interact with the ring when the thread breaks or with a hook that is mixed with this ring when tightening the thread. The device has a lever gear for mixing one of the gears, which is activated by the density change lever in the underside.

The drive shaft of the gears for feeding the yarns is provided with a ratchet clutch and lever transmission for its disengagement, driven by a cam gear of the stepped eccentric.

FIG. 1 shows a front view of the device; in fig. 2 is a side view of the device; in fig. 3 is a view along arrow L of FIG. 2; in fig. 4 is a schematic view of the ratchet clutch assembly;

The fixture is driven by a crank gear / automatic gear coupled to the spur gear 2, freely seated on the drive shaft 3jYs 107021

Gear 2 from the end has teeth that engage with ratchet clutch

4 clutch, having a longitudinal movement of the pinch, fortified pas shaft 3.

The force feed is produced by a pair of drive gears 5 and 6 made of an elastic material, such as vinyl plastic, in order to provide a more uniform thread feed.

Gears .5 and set in motion through bevel gear pairs 7 and 8. For ease of threading, the bristles are pressed by a lever 9 pivotally connected to a bracket 10 carrying the gear 6. The gears 5 to 6 are clamped by a spring 11.

The yarn feed magnitude is changed by pushing the gears 5 t 6 by means of a lever 12, which interacts with a pull 13, passes through guides 14 and 15 and rests against the bracket 16, mounted on the sleeve of the density lever 17 at the stop / 8, mounted on the arm 19, serves to regulate the stroke of the lever 12, and the screw 2 (9 - to adjust the clutch gears

5 and 6.

Turning off the filing of the thread, for example, when it comes to knowing the bead, the heel and the toe, occurs due to the action of the cam 21 attached to the bristle 22 of the stepped eccentric (not shown) on the lever 23.

The lever 23 deflects the lever 24 and the fork 25, while disengaging the ratchet 4 with the gear 2, as a result of which the rotation of the gears 5 and 6 stops.

To provide a clearer shutdown of the machine when the thread is broken or tightened, there is a rocker arm 26 and a driving rotary ring 27 on which two studs 28 are fastened. When the thread is broken or tightened, the ring 29 suspended on its loop moves vertically on the guide 30 bracket 31, and strikes the end of the rocker arm 26, as a result of which the other end of the rocker arm rises and gets under the influence of the studs 28 of the rotating ring 27. When the stud strikes the end of the rocker arm, the latter rotates together with the holder 32, freely rotate eys in the rack 33, and entrains the pull rod 34 connected to a latch lever 35 turn off the machine. The return of the holder 32 and the yoke to the initial polishing is carried out by the spring 36.

When the thread is tightened, the ring 29 rises, touching the wire 37, which raises the hook 38.

Hook 38, when lifting with its end, brings the end of the rocker arm 26 to the studs 28 of the rotating ring 27, and the machine gun is turned off, as already indicated.

Prev Invention

1. An attachment to a round billet, for example, a self-fusing machine for forcing a yarn, made in the form of a pair of driving gears for feeding the yarn, a thread loop from the thread loop, a mechanism for turning off and changing the feed of the gears, the thread and the mechanism for turning off the machine when the break or tightening the thread, characterized in that, in order to provide a more uniform feed of the thread, in particular from caprone, the gears for feeding the thread are made of elastic material, for example vinyl plastic 2. The form of An assembly according to claim 1, characterized in that, in order to provide a clearer switching off of the machine when the thread is broken or tightened, it is provided with a bead which is connected with a latch of the machine off lever and a drive ring with a pin 15) to turn the rocker arm .
