SU107521A1 - Adaptation to the winding mechanism for reserve winding of the thread on the bottom of the spools of ring-twisting machines - Google Patents

Description

The subject of the invention is to adapt a winding mechanism for reserve winding of a yarn on a bottom shiul ring-twisting machine with manual switching off and automatic switching on of a winding mechanism and a device for determining the length of the winding of a reserve yarn, have an index for u and y.

The proposed design, in comparison with the known designs of the same purpose, makes it possible to simply adjust the length of the winding of the reserve thread in this way and the limits.

For this, the device for determining the winding length of the backup thread is made in the form of a worm gear receiving movement from the exhaust cylinder, inside the worm gear of which there is an overrunning roller clutch, giving them a pivoting movement of the hub on the same axis.

The sleeve is equipped with a finger, which, at the time of winding, frees the obstruction pin connected through a double-arm lever and is spring loaded with the lever to manually turn off the winding mechanism.

FIG. 1 shows a side view of a device with a worm pair shown in a vertical section; on phpg. 2-vnd but arrow A on fng. one.

In case 7 there is a worm

wheel, i and cherv

receiving

BpanieHHe via P1)) transfer from the exhaust cylinder of the ring-twisting machine.

Inside the worm wheel mounted overtaking roller clutch 4.

On the same axis; with sleeve 4, a sleeve 6 is mounted with a finger, with a rigidly mounted handwheel 7 at the end.

In the lower part of the housing 1, a locking latch is installed, resting on the roller .9 and held in this position with the help of a spring / (,) and a bar //.

The overrunning clutch 4 has oblique cuts, which are slots for its rollers. When the handwheel 7 is rotated clockwise, the clutch is turned, and its rollers at this time are deflected to the side

larger slice, ii worm wheel .i motionless.

The handwheel does not have the ability to rotate in the opposite direction, since the clutch rollers are installed while holding and clamping the clutch in the worm wheel.

The locking pin 8 is connected to the two-armed lever J3, pivotally connected to the spring loaded pull 13, fastened to the lever W of manually switching off the winding mechanism.

In front of the machine, the handwheel 7 is turned clockwise so that one of its protrusions, red and red, stands on the mark in the rear / on the body 7 and corresponding to the given winding length of the standby NC (in red on the handwheel 7 ikrapshn ledge, located in idle position against the finger 6).

Then, pulling the handle / 6 and turning the lever J4 down, turn on the winding mechanism.

In this case, the ha / o is lowered, and the locking latch 6 rises and its upper end, which, under the action of the spring 10, moves onto the bar 11, engages the roller 9 and holds the spring 17 in a compressed state at the lower position of the lever 14,

After the maschine is put into operation, the backup thread is wound onto the bottom of the pole. Together with the screw pair, the sleeve with sleeve 6 and pin 6a rotates.

At the time of the end of the backup

winding the finger 6a comes to the locking latch 8 and drops it from the roller 9, while the spring .77 opens the lever and raises the lever 14 with the handle 16.

The rod 18 of the handle 76, under the action of the spring / 5 located inside it, enters the hole of the bar SO and thereby locks the lever 4 in the upper position. From this point on, the winding of the backup yarn stops.

When lifting the lever Ы and ти 13, the latch is locked (5 occupies the initial position.

Subject invention

Adaptation to the winding mechanism for the backup winding of the thread on the bottom of the ring-twisted mapping with manual shutdown and automatic activation of the winding mechanism and the device for determining the length of the winding of the backup thread, having a length indicator, characterized in that, in order to adjust the length of the winding of the backup thread, The device for determining the winding length is made in the form of a worm gear pair that receives movement from the exhaust cylinder, inside the worm gear of which an overrunning roller clutch is mounted, communicating The turning movement of an axis, which is sitting on the same axis, has a finger, which, at the end of winding, gives off the locking latch, connected through a two-arm lever and spring-loaded with a lever for manually switching off the winding mechanism.
