SU98622A1 - Adjustment to a knitted, for example, circular, machine for switching it off when the thread is broken or tightened - Google Patents

Description

The subject of the invention is to adapt to knitted, for example round, machines for switching them off when the thread is broken or tightened, made in the form of thread guide rollers, an unbalanced lever with a thread guide roller supported by a thread loop, two contacts closed by a lever when the thread breaks or thread tightening, and included in the stump of the contacts of the electromagnet, acting on the mechanism for turning off the drive of the machine.

A feature of the proposed device is that to adjust its sensitivity by changing the magnitude of the effect of the thread loop on the roller of the unbalanced lever, the thread-idling rollers are installed with the possibility of rearranging them to change the shape of the thread loop. Thanks to cBoeii, the compactness of the device can be set according to the number of all threads on multi-system knitted round machines without removing the part of the fabrication of their systems.

FIG. 1 shows a general view of the device; in fig. 2 - view it

on the side: in FIG. 3 is a section through it in AL in FIG. 2

The base / attachments are mounted on a knitted round machine.

A box 2 is attached to the base in which the contact lever 3 and two insulated contacts 4 n 5. are attached. The contact 4 closes directly with the contact lever when it rotates to the right, and the contact 5 closes with a spring-loaded lever 7, which is freely mounted on the axis 6. lever when turning it to the left.

On the basis of mounted podnnzhny thread guide roller 8 mounted on an unbalanced lever, porcelain thread roller or peephole 9, thread extension roller 10, adjustable along the horizontal spline thread guide roller or peephole 11 and roller 12. Unbalanced lever 13, on which the movable roller S is freely mounted, through it, pads 14 fastened with a sleeve 15, which is fixed

pin lever 3. The sleeve 15 is freely mounted on the axis 16.

The thread 17 from the bobbin goes into the peephole 9 and slides into the folding rollers 10 and 12; then the thread goes around the roller 8 and, in the form of a loop, passes through the peephole 11 into the machine's idle system.

By rearranging along the horizontal slot the base of the worm 12 and the peephole 11 can be changed {in the direction of the thread-loop branches, on

when the roller 8 is held by the unbalanced lever 13, the pressure of the thread loop is increased;

by 8 at the approach of roller 12: with eye / 7 and reducing this effort

prn WS splitting, it reaches a settlement, the sensitivity of the device.

When the thread breaks or disappears in the thread loop branch, the tension drops sharply and the roller 5 under the action of its weight lowers, and the lever 13 with the pad 14, sleeve 15 and the contact lever 3 rotates. When rotated counterclockwise, the contact lever 3 with its free end closes the insulated contact 4, connected together with the base of the device into an electromagnet circuit (not shown), which affects the mechanism for switching off the drive of the knitting machine.

When the thread is tightened, the tension of the thread branches increases, as a result of which the roller 8 together with the lever 13 rises, and the contact lever 3 rotates clockwise, presses the lever 7, which, having overcome the action of the spring 18, turns on the axis 6 and closes through contact 5 is the circuit of an electromagnet acting on the mechanism for switching off the drive of the machine, as a result of which it stops.

Subject invention

Adaptation to a knitted, round machine, for turning it off when the thread is broken or tightened, made in the form of thread-like equalizing rollers, an unbalanced lever with a directional roller supported by a thread loop, two contacts closed by a lever when the wire is cut or tightened and turned on contacts of an electromagnet acting on the mechanism for switching off the drive of the machine, characterized in that, in order to regulate the sensitivity of the device for changing the magnitude of the effect of the thread loop on the roller, it is unbalanced On the left arm, the thread guiding rollers are mounted with the possibility of rearranging them to change the shape of the thread loop.
