Description

(54) MAJOR MOBILE LAYER REGULATOR

I

The invention relates to textile manufacturing, in particular, to the main regulators of the loom.

The main regulator of the weaving machine is known, which contains an arbor diameter control and a double-shouldered rach g, on one shoulder of which a rock is pivotally mounted, and the second shoulder is profiled and connected kinematically with a diameter probe and with a roller installed so as to be in contact with the face cam, fixed on the friction disc, the summation of the signals from the navo diameter probe and the rock, which is the controller of the warp, is carried out in fact by means of a cam device having profiles of shoulders rock lever 11.

The disadvantage of this basic regulator is the lack of clear work with changes in the diameter of the winding of the main yarns on the core, as well as the difficulty of manufacturing the PROFILE lever.

Closest to the proposed main regulator of the loom, containing

the rock mounted on the lever is kinematically connected to the rocker mechanism, the lever of which is kinematically connected with the probe for contacting the main threads on the main 2.

The backstage stone is mounted on an eccentric axis, which is hinged and kinematically connected to a lever that carries a rock.

The disadvantages of such a regulator are

10 limited gain of the signal transmission from the rock to the stone KULIS through the eccentric axis, and also the non-linear law of change of the transmission gain, which leads to a change in sensitivity

IS of the main regulator in case of its changeovers and decrease in the quality of the fabric produced

The purpose of the invention is to increase the stabilization of the tension of the main threads.

Claims (2)

This goal is achieved by the fact that a kine20 link between the link arm and the probe additionally includes a double-arm lever, the axis of which is pivotally connected to the link arm, one shoulder of the double-arm lever is kinematically 391 connected to the probe, and the other is connected to the lever, not drying the rock. The drawing shows a flow chart of the main regulator of the weaving machine. The main regulator of the weaving machine contains a lever 1, on one shoulder of which a hinge is installed) rock 2, and the second shoulder is connected to one shoulder of the sum of 1 ×) un) levers 4 through the tr 3. The regulator is also equipped with a probe 5 of diameter 6, made in A double arm, one arm in contact with the main yarns on the base, and the other through a pull 7 connected to the other arm of the summing lever 4. To ensure the contact of the probe 5 with the surface of the spring. A spring 8 is provided. The total lever 4 is installed on the lever 9 s 10 situated on the stone crank 11 mounted on shaft 12 .. The axis of rotation 13 .rychaga wings 9 placed upon the races 10, 14 of a double-armed lever arm mounted on the shaft 15, on which the shoulder 16 is located roller 17 ,. The roller 17 is mounted with the possibility of contacting with an end cam 18 fixed on the friction disk 19, which is kinematically connected with its arm. 1 The main regulator of the weaving machine operates as follows. The main threads are periodically released from the base by contacting the roller 17 with the surface of the face cam 18 mounted rigidly on the friction point 19. With a decrease in the diameter of the winding of the main threads, the angle of rotation is increased as follows. As the main threads are sabatiyuyu with 6 diap 5 diameter, the diametrically rotates clockwise, through the t 7 turn, add lever 4, mounted on lever 9 backstage Sh. Thus, the position of the mounting arm of summing arm 4 to lever 9 backstage 10 and, therefore, , moving vs backstage 10 relative to shoulder 14. the two shoulders is determined by the weaving diameter of Navo. In the same relation, the position of the end of the lever 14, turning 1 (the axis around the axis 15) changes. The roller 17, located on the first shoulder 16 of the double-arm lever, is shifted in the direction of the face cam 1c fixed on the friction disk 19, is turned by an angle, the magnitude of which is is determined by the diameter of the winding of the base on the front. Changing the position of the summing lever while decreasing the diameter of the threads does not affect the position of the rock on the left, because with a decrease in the diameter of the threads, the probe 5 of the diameter rotates clockwise , raise the level 7. In this case, the summing lever rotates clockwise relative to the pivot point of summing lever 4 and rod 3, this causes the lever 9 to rotate and the roller 17 moves, and the position of the rock remains unchanged. tensioning the warp threads changes its position, transmitting the signal through the pull 3 and the summing lever 4 to the lever 9 with the wings 10. In this case, the summing lever 4 is rotated relative to the hinge point of the summing lever 4 with the tension 7. Thus Thus, changing the position of the summing lever while decreasing. . Thread diameter does not affect the transfer of the signal from rock to rocker. In this case, the coefficient of signal transmission from rock to the wings is a constant, independent of the position of the summing lever (and therefore, of the diameter of the winding of the base), i.e. the connection between rock and backstage is almost linear. The main regulator of the weaving machine with the summing lever allows you to keep almost constant parameters of the machine refueling and the tension of the axial threads during the entire period of operation of the weaving machine with any diameter, which improves the quality of the fabric produced on the machine. The formula for gaining, the main regulator of a weaving machine, contains a rock mounted on a lever, kinematically connected to a rocker mechanism, the link arm of which is kinematically connected with a probe for contact with the axis of a yarn, and and with the fact that, in order to stabilize the tension of the main threads, the link between the link arm and the probe additionally includes a double-arm lever, the axis of which is sariirno connected to the link arm, one shoulder of the two-arm lever is kinematically connected with the probe, and the other with a lever carrying a rock.
