SU88171A2 - Adaptation to circular beaters for switching on the spare yarn feeder - Google Patents

Description

BASIC Auth. St. No. 58192 describes an adaptation to circular circular automatic machines for switching on a spare yarn feeder while loosening and tightening the filament, controlled from the feeding grid. The lattice is kinematically connected with the lever for switching the yarn feeders by means of a rotatable spring-loaded shoe and sleeve with a shaped edge that interacts with the lever for switching the yarn drivers and with the rod of the lattice trigger mechanism.

The described device is a further improvement of the device according to the author. St. No. 68192 and is characterized by the use of a trapezoidal wedge mounted on a vertical rotatable rod of the lattice trigger mechanism to switch the spare and main yarn feeder to the starting position simultaneously with the rotation of the rod to lift the lattice.

FIG. 1 shows a front view of the device; in fig. 2 is a view along the ab in FIG. one; lf FIG. 3 - wedging; in fig. 4 is a mechanism for switching on and off yarn feeders.

The spare / and main 2 yarn feeders of the circular-juicy automaton are mounted on axis 3, with the main yarn feeder receiving movement from the elevator 4.

On the thread-feeding ring with two screws fasten the bracket 5 on which two levers 7 and 8 are mounted on the axis 6, which are intended for switching on and off both thread-carriers.

To control whether the main thread 9 is broken or tightened, a trigger is applied, on which a handle 11 is rigidly seated on a non-JO which has a trapezoidal wedge 12 attached,

interacting with levers 7 and 5 to switch the yarn feeders to their original position when lifting the grating.

During normal operation of the machine, i.e., when the needles receive a thread from the main yarn feeder, the handle // is in the position shown in FIG. 2, while the back shoulder of the lever 8 is in the same plane of the wedge, as a result of which the front shoulder of the lever is pubescent and, interacting with the shoulder of the spare yarn feeder, keeps it in the off position.

At the moment of thread breaking or tightening, the rod 10 is rotated clockwise by the action of the spring of the trigger mechanism, as a result of which the handle 11c with the wedge 12 takes the position indicated in FIG. 2 dotted line. The spare yarn feeder 1, freed from the action of the rear lever of the lever, under the action of the yarn guide spring is lowered to the non-operating position and feeds the thread 13 from the spare spool. The back shoulder of the lever 7 rises, slipping along the edge a and then along the edge b of the wedge 12. The front shoulder of the lever 7 is lowered and, interacting with the shoulder of the main yarn feeder 2, turns it off.

Restoring the working position of the main yarn feeder, as well as charging the trigger mechanism after eliminating the causes of thread breakage or tightening, is done simultaneously by turning the knob // to its original position (counterclockwise). In this case, the back shoulder of the lever 7 is lowered, slipping along the edge a of the clip. The main yarn feeder is activated by the thread spring and starts feeding the main thread 9 to the needles. Then, the back shoulder of the lever 8 rises, sliding along the run and its edge into the wedge. The front shoulder of the lever is lowered and, interacting with the shoulder of the spare yarn feeder, turns it off.

On the elevator 4 of the main yarn feeder, there is a protrusion g, designed to turn off the spare yarn feeder when switching the machine to the production of heel.

Subject invention

The form of making adaptations to circular blender machines for switching on the spare yarn feeder while loosening and tightening the thread according to the ed. St. No. 68192, except for the fact that, in order to simplify the design of the device, the trapezoidal IV.THH mounted on the rotatable rod of the Trigger Grid Mechanism and interacting was used to simplify the design of the device. with levers for switching both yarn feeders.
