SU98197A1 - A device for making a reserve of weft yarn on spinning or twisting machines - Google Patents

Description

BACKGROUND OF THE INVENTION The invention relates to a device for producing a reserve of a weft yarn for a spool for automatic weaving machines. The reserve time is produced by spinning or twisting machines at the beginning of ear earning with the spool when the ring bar is stopped.

The proposed device allows to operate without a weaving and winding machine, providing a backup winding of the thread, similar to the winding, obtained for the weft 10-winding machine.

A feature of the proposed device is that to disconnect the eccentric from the winding drive, a screw plug driven by a separate handle is used, and a device is installed on the head for visual control of the length of the backup winding thread, made in the form of two coils mounted on the ends of the swivel arm shoulders alternately cast into the opposite direction of the exhaust cylinder of the spinning weft or twisting weft machine and rewinding the control thread length

FIG. 1 shows a transmission scheme for a symmetric eccentric and the mechanism of its insertion and deactivation; in fig. 2-way circuit scheme for visual inspection of backup length; in fig. 3 is a view of it along arrow A of FIG. 2

To turn off the symmetric eccentric / skulchit e., And by hand screw plug 2, the position of which is set by the handle 3. The device for visual control of the reserve is a device: a double-arm swivel on the 1 head of the machine, two coils 5 and 6 were mounted, alternately driven into the exhaust cylinder of the machine 7 from the sheikts 7.

The operation of the winding mechanism on a twisting machine, for example, type. consists in, it is:

1. Item position; the winding mechanism when making a rent (reserve).

Gear gear 6 handle 3 through a screw plug 2 pulling out of the coupling with the winding gear 9 (Fig. 1).

The face bar is set in the lower position-moment of the reserve operating time. Simultaneously with the stopping of the short-cut N. taikn, the symmetric eccentric / with a small diameter is placed in the lower position and the roll of the lifting lever is located in the excavation of the eccentric.

A coil with a wound thread) of a given length pahodpts in the upper position, and a kathlika without winding-ia Iike 7 in the articulated manshna cylinder. In this iozhenozhneni parts maip1 vk / night and it continues to work until the operating time of the reserve on jnny.iio.

The accumulation of the reserve occurs due to the fact that the Toez board is in place during the development of the cut, as gear 8 is removed from the scene from the horn of 9, and therefore, the symmetrical extract is rotating (Fig. 1 ).

The length of the reserve yarn on the base is controlled by winding the yarn from one catupsi to another npk 7 of the exhaust cylinder of the exhaust cylinder, to which the cast iron 6 is pressed (Fig. 2). The time of winding the thread from the coil 5 to the coil of 6

Subject invention

1. A device for parabotting a reserve of a weft yarn on spinning or twisting manshnas with switchable off and operating time of the winding eccentric, characterized in that, in order to simplify the design, a manual drive spindle, mounted on the frame and connected by a hinged coupling, is used to switch off the eccentric a guitar

determines the paraoot time for the reserve thread length per Hjr; v.Tio.

. 2. The position of the parts when the removal work after the reserve.

After working up the reserve length on the turn of the machine, rotating the handle 3 of the handle 3 is inserted into the test of H esterH1O 6 with the HJ system 9, which makes it possible to activate the whole mot.tny mechanism, whose operation is suspended as it is on the usual K-83 torsion mantel .

For the normal scene 1P1 Isthester 8 V: 9 and the composition / yu limiter 10, and in order to run them off OCh1M1 and put the disk // and lock 12, fixing the position N1 sterpi 8 during the operating time of the volume.

3. The position of the details of the nose.

After working off the complete removal, the main gear is stopped and the ring is lowered, as is the case with conventional K-83 type machines. In addition, at the same time the handle 3 of zailenn 1 sternii 8 and 9 is derived at the same time, and the position of the details of the winding mechanism occupies the original position indicated in section 1.

After stopping the machine, lever 4 rotates; at the same time, the upper catapun, not having a thread, is placed on the neck 7 of the upper cylinder, and the lower one is raised: up.

and an intermediate gear, coupled with an eccentric gear.

2. Application in the device of a device for visual coptol of the reserve thread length, in the form of two coils mounted on a pivotal traverse, which are alternately in contact with the outlet challinder, to rewind the control inti from the catupzhi to the coil.
