The invention relates to textile engineering, can be used on weaving machines for adjusting the tension of the warp threads, and is an improvement on the auth. No. 1211356.

The purpose of the invention is to reduce the openness of the main yarns by increasing the uniformity of their tension at the time of the formation of yarn and around the weaving yarns.

FIG. Figure 1 shows the regulator of the tension of the warp threads with a means for controlling the rotational speed on the back, made in the form of a single-stage elliptical gearing; in fig. 2 the same, with the means for adjusting the rotational speed of the navo, made in the form of a canoid variator.

Tension regulator of the warp threads contains 1, drive 2, navo, means 3 for adjusting the rotational speed of navo 1, mounted on dial shaft A, control unit 5, movable rock 6 or tension adjuster for warp threads, sensor 7 for tension of warp threads, made in the form of a moving rock moving transducer into an electrical signal, an additional tension sensor 8 mounted in front of rock 6. Drive 2 contains a worm gear; Transmission 9, kinematically connected through differential 10 and planetary gear 1 1 with adjustable lektrodvigatelem 12 and shaft 4 through dial-up to the means 3 controlling rotation speed navo 1.

The rotation speed adjusting means 3 1 is made in the form of an elliptical single-stage gear 13 or includes a cam mechanism 1A and a canoid variator 15, the control disk 16 of which is kinematically connected with the cam roller 17.

The regulator works as follows.

The movement from the adjustable electric motor 12 is transmitted through the planetary gear 11 and is differentiated. Lu 10 which adds the variable frequency of rotation of the electric motor 1 2 and the variable frequency from the means 3 for adjusting the rotational speed of the shaft 1, mounted on the key-shaft 4. Complicated frequency

The rotational speed is transmitted by worm gear 1. The variable frequency of rotation of the adjustable motor 12 is determined by the control unit 5 depending on the change in the tension of the warp threads, taking into account the position of the movable rock 6 and the resultant additional rock, depending on the change in the winding radius. The rotational speed of the electric motor 12 determines the rotational speed of 1 and the tension of the warp threads, depending on the position of the movable rock 6 and the change of the radius on the ground 1.

The rotation speed adjusting means 3 1 determines the rotation speed 1 and the tension / 1 thread of the warp at the time of shedding and weft threads. The control unit 5 of the electric motor 12 ensures the stabilization of the speed and the constancy of the moment developed by the electric motor 12 in a steady state.

The use of a fast-acting means of controlling the rotational speed provides the necessary precision in adjusting the tension of the warp threads at the time of the yawning of the main threads and the weft threads. I

Claims (3)

1. The tension adjuster of the warp threads on the loom auth. No. 1211356, differing from the fact that, in order to reduce the breakage of the main yarns by increasing the uniformity of their tension at the time of yawning and weft yarns, it has a means of adjusting the rotational speed set on the dial shaft and connected to the differential . 2. The regulator according to claim 1, about tl and - due to the fact that the means adjusting the rotational speed is made in the form of a single-stage elliptical gearing. 3. The regulator according to claim 1, about tl and - due to the fact that the means adjusting the rotational speed includes a cam mechanism and a kanoid 1 variator, the controlled disk of which is kinematically connected with the cam roller mechanism.
