Description

(54) UNIT FOR WRINKING THREAD

one

The invention relates to the manufacture of machines for forming chemical fibers, in particular to devices for winding thread, used on spinning and twisting-stretching machines with hydraulic drive.

A device for winding a thread contains a bobbin holder, which is set in motion by means of an adjustable drive controlled depending on a change in the diameter of the winding and the tension of the thread. In this device, the bob holder is driven as an air turbine, mounted on the holder spindle, with adjustable feed and discharge of compressed air depending on the change in the winding diameter and the thread tension.

It is also known a device for winding a thread, which is closer to the proposed one, contains its holder — a package mounted on an annular plate brought into reciprocating motion by means of a rack mechanism, a thread guide, a torque hydraulic motor, kinematically connected with a rack mechanism, an annular plate motion speed controller and a winding programmer.

The control system of the hydraulic motor must ensure its reversal, adjustment of the speed of movement of the annular plank and change

the amplitude of the stroke of the bar or its displacement relative to the initial position.

The reversing of the motor is carried out using a hydraulically controlled reversing valve with switching cams, the shaft of which is mounted on a toothed rack. During operation, the hydraulic motor moves the rail with the cams turning the handle of the control valve, which supplies the working fluid to the reversing slide, moving its plunger. Depending on the position of the plunger, the cavities of the hydraulic motor are alternately connected to the paporno or drain lines.

The form of winding the yarn on the package is determined by the geometry of the cams and the number of revolutions of their rotation during the working time of the package. The speed of movement of the ring bar is regulated by a throttle mounted on the drain line by changing the flow rate of the fluid passing through the hydraulic motor.

The winding pattern can be achieved due to the displacement of the annular stripe constant along the amnlitud. In this case, the rotation of the cams is communicated from the inclined guide line through the ratchet mechanism. The rotational speed of the cams is varied by adjusting the angle of inclination of the direction of the ruler and its ruler. If the winding form

formed by a constant reduction in the amplitude of the stroke of the annular plank, the cams make one revolution during the time of the package. Movement to the cams is transmitted either from the individual electric motor or from the drive of the machine.

However, the known device is characterized by the difficulty of adjustment when changing the shape of the winding, which requires changing the cams, connecting their shaft with either a gearbox or a guide bar.

The purpose of the invention is to expand the functionality of the device design to obtain any form of winding with a minimum expenditure of time and machine reconfiguration during the transition period from one form of the winding to another.

This is achieved in that the proposed device has a hydraulic booster associated with a torque hydraulic motor and a speed controller, and a reversible electric motor. The irogram sensor is electrically connected to a reversible electric motor, the output shaft of which is connected to the hydraulic booster slide, while the hydraulic booster and the torque hydraulic motor are covered by mechanical feedback. The transition from one form of winding to another is provided by the program of the electronic control system of the reversing electric motor, due to which any law of motion of the ring bar can be set, which makes it possible to obtain the necessary form of winding.

FIG. 1 is a schematic diagram of a device for winding a thread; in fig. 2 shows the power steering, longitudinal section.

The package holder 1 is mounted on an annular bar 2, which is brought into reciprocating motion by means of a rack and pinion mechanism, the rack bar 3 of which moves along the vertical column 4 by connecting the bar with the gear bar 5 rotating with the torque motor shaft 6. The speed of the ring bar is adjusted The regulator is 7.

The device is equipped with a hydraulic booster 8, which consists of a spool 9 and a distributor sleeve 10. The hydraulic booster is rigidly connected to the output shaft of the reversing electric motor 11, which is electrically connected with the winding programmer 12. Power and torque hydraulic drive4

The body is covered by a reverse mechanical connection, in which the shackle 13 is used. In addition, the hydraulic booster is connected to the pressure and drain lines of pumping station 5 of station 14.

The device works as follows. The thread 15 passes through the thread guide 16, tucks under the slider, worn on the spinning ring, and is wound on a cartridge rotating with a spindle.

The electronic system of the programmer 12 winding according to a special predetermined program provides the necessary law of winding U and uff; 1 em movement of the reversing electric motor AND, which turns the spool 9 of the hydraulic booster. When the valve is turned, the corresponding lines are opened, which serve to supply and discharge the working fluid to the hydraulic engine. The rotation of the hydraulic motor shaft through the reverse mechanical link-link 13 is transmitted to the distribution sleeve 10 of the hydraulic booster, which rotates in the same direction as the spool 9. The amount of lag of the hydraulic motor shaft from the spool is determined by the speed and torque of the hydraulic motor shaft, which is regulated with using a speed controller. Hydraulic through gear 6 and gear

Q rail 3 reciprocates the annular plate with the package holder. As a program with the aid of a software probe 12, any law of motion of the ring bar can be set and, therefore,

5 any form of winding thread.
