(54) MECHANISM PAYMENT COMPENSATION MECHANISM FOR THE INVOLVING LOWING MILL

The purpose of the invention is to simplify the design of the computation mechanism and increase the reliability of the weft yarn.

This goal is achieved by the fact that the drive of the yarn feeder contains a link mechanism, on the side of which the yarn drive is mounted.

FIG. 1 shows the mechanism and the view, in plan; in fig. 2 and 3 are embodiments of the mechanism. - The weft yarn compensation mechanism for the shuttleless loom contains a yarn feeder 1 with a peephole 2 for the weft yarn .3. The axis 4 of the yarn guide is installed with the possibility of re-installation in the slot 5 of the bracket.

The drive driver is installed in the form of a piece of ogrom- khanizm, on the cupis 6 of which the yarn feeder 1 is freely installed. The stone 7 of the backstage is mounted with the possibility of adjustment on the flywheel 8 fixed on the main shaft 9 of the machine.

The weft thread 3, unwound from the reel 10, passes through the 11th eye of the peephole 11 of the eye 2 of the yarn feeder 1 and further to the nozzle 12 of the right feeding rapier.

The thread guide 1 can be driven by a finger 13 fixed on the flywheel 8 of the main shaft 9 of the machine, and the axis 4 of the yarn guide is mounted on the stone 7 backstage, which allows to simplify the law of motion of the thread guide and also reduce wear of parts (Fig. 2).

The swing axis 4 of the yarn feeder can be rotated by curvature – tenon 14 from the intermediate shaft 15 with an angular speed equal to the speed of rotation of the flywheel 8. In this version of the mechanism, the adjustment of the stroke of the eye 2 of the yarn feeder 1 and the speed of the forward and reverse strokes the position of the crankshaft 14 relative to the angular position of the flywheel 8,

During the operation of the mechanism, the rotation of the flywheel 8 is converted into a swinging movement of the yarn feeder 1 with an eye 2 by means of the link mechanism. top corresponding

feeding the weft yarn in the nozzle 12 {"Feast Blappdar to this, starting from the moment the rapier leaves the pharynx and until the rapier stops in the extreme positions beyond the pharynx, the yarn guide 1 with ivia3KOM 2 works on reproducing the extra length of the laid weft yarn in order to achieve the required tensioning it across the entire width of the gmpravka and retraction of the protruding end of the

Noah thread rapier. This improves the conditions and, consequently, the reliability of rewinding of the thread from the rapier to the rapier.

The design mechanism is simple and noaaonj em to regulate the course of the yarn feeder, in particular, the moment of filing the thread in the rapier nozzle and the length of the accumulated loop of the weft thread. The adjustment of the thread guide motion is carried out by moving the stone 7 of the scenes and the axis of the thread guide along the groove of the flywheel 8 and

groove 5 bracket. The mechanism allows

also control the end of weft ichi protruding from the rapier and resulting from cutting the laid weft yarn at the moment of the initial position of the rapier

outside the throat.

A simple adjustment of the mechanism allows the filament to be fed into the right rapier nozzle so that the time when the thread leaves the graft of the rapier coincides with the moment when the rapier meets in the center of the throat. It also increases the reliability of the transfer of the thread from the rapier to the rapier.
