    The invention relates to textile machinery, in particular to a batten mechanism of a weaving machine for perfect terry cloth. A baton loom mechanism for producing terry fabrics is known, containing a reed, pivotally mounted by means of rocker arms on blades mounted on a batten shaft, connected to an electromagnetic control system; means for additionally shifting the reed having a profile element connected to the rocker arms by means of an eccentric bearing shaft; a wheel mounted on a shaft and a gear sector coupled to it, mounted on the machine frame, a vertical lever connected to the gears with an upper arm th sector and bottom by rods - with designed as a spring-loaded lever pusher cam mechanism, and means for adjusting reed progress made in vnde clamp pivotally mounted on m n connecting the lower arm vertically second lever with a pusher cam mechanism l. A disadvantage of the known batun mechanism is the low reliability of operation, due to the fact that the camshaft and the forked levers are mounted on the fixed hooks of the weaving machine. In this mechanism, there is a relative slip between the set of pushers and the forked levers, which requires appropriate lubrication. Moreover, due to the fact that the fork arms are installed on the machine shuttle below the terry cloth produced, lubricant can get onto the fabric and spoil its coating. In addition, the return springs that maintain contact between the pushers and the forked levers, due to the reciprocating motion of the bat and the reed, are in a tight state, due to which they are easily subject to breakage. The purpose of the invention is to increase reliability and improve operating conditions. Tse, Sh1 is achieved by the fact that in the batumine mechanism of a loom for producing terry fabrics containing a reed, pivotally mounted by means of rocker arms on blades mounted on a batten shaft, associated with the system is an electromagnet of control and means of additional bias of the reed having a profile element connected to the rocker MP by means of a shaft carrying an eccentric, a gear wheel installed in the shaft, and a gear-linked sector coupled to it mounted on the machine’s axis®, vertical lever, connected to the upper arm with the toothed sector, and the lower with the help of a pull with a cam follower made as a spring-loaded lever, and a device for adjusting the stroke of the reed, made in the form of a collar hinged on; connecting the lower arm of the vertical lever to the cam mechanism, the eccentrics are connected to the rockers by connecting rods, the shaft carrying the eccentrics is mounted at the base of the blades on the batten shaft, the toothed sector is freely mounted on this shaft, the profile element is in the form of an arc-shaped groove the upper arm of the vertical lever, and its connection with the toothed sector has two pivotally connected rods, one of which is pivotally connected to the blade in its lower part, and the other - pivotally with The ubiquitous sector, with the hinge connecting the thrusters between them, is placed in the groove of the vertical lever, the protrusion is made on this lever, and on the machine frame there is a stop for it, to which the lever is spring-loaded. In addition, the ha of the means of additional bias of the reed is made of two rods mounted on a vertical lever at different distances from its axis of rotation and with the possibility of alternately connecting with a pusher from an electromagnetic control system, while the pusher has axes, and a longitudinal rod grooves for them. At the same time, it is envisaged to perform an arcuate groove of the profile element along an arc of a circle, the center of which lies on the axis of the batten shaft. On fig.D. shows a weaving machine with, pr. The proposed batan mechanism, a cross section, on fig. 2 - section A-A in Fig. |., Fig. 1 shows the bed 1 of the weaving machine and the threads 2 and 3 of the warp, passing through the heel 4 side: frames 5. Gotau cloth 6 is transported by the tension roller 7 sliding on the aod roller .8, supported by the shuttle 9 loom. A commercial roller 10 serves to wind the finished fabric. The batan 11 is hinged on the bed 1 by means of an axis 12 and supported on the main bar of the bat 13 direction 14. The reed belt 15 is rigidly mounted on the top of the support 16, to which are attached, The telephones 17 (figure 1 shows only one pusher, are inserted into suitable grooves 18 in the main bar 13 of the submerge 11, and are pivotally attached to the main bar 13 with pivotally mounted pins 19. Each pusher or lower end of the pushers 17 is pivotally attached to end the connection About the lever 20, the other end of which is loosely mounted on the corresponding cam 21, all the cams 21 (only one shown in FIG. 1) are fixed on a common shaft 22 which is rotatably supported by the yoke 11 near the axis 12. means / not shown in the drawing the wheel 23 is fixed on the cam shaft 22 and engages with the toothed sector 24 supported by element 2 freely mounted on the axis 12 of the battis 11. The supporting member 25 is also pivotally attached to the lower end of the batt 11 by means of two levers 26 and 27, which are hinged are jointly connected, and their common connection 28 is inserted and guided into another hole 29 in the vertical fork-type swinging lever 30. The swinging lever 30 is pivotally attached to the weaving loom by the finger 31 at the lower end of the arc hole 29 so that the distance of this end from the axis 12 of the batan remains constant regardless of the lever 30. Swinging pin 30 is supplied to the stand 32, which is maintained in a state of rest by spring 33 on the fixed protrusion 34 of the bed of the weaving mill Arc hole 29 is formed so that it Toit from the arc having a center on the axis 12, when the swinging lever 30 is located on the protrusion 34. By means of the blocks 35 and setscrews 36 with different corresponding points on the two shanks of each vertical fork 30 (in Fig. 1, only one shank, the other lies below) the ends of the two rods 37 and 38 are pivotally connected, with the other ends of the rods being inserted into the respective vertical parallel grooves 39 and 40, respectively (Fig. 2) in the control lever 41, where the rods are located on support rollers 42 freely mounted on finger 43, p The supported control lever 41 at the lower ends of its grooves 39 and 40. The control lever 41, which is pivotally attached at point 44 to the bed of the weaving machine, has its own sliding roller 45, resiliently held by spring 46 in contact with the profile of the control lever 47, hingedly connected to the bed of the loom and driven by means (not shown, the control lever is supported on two opposite sides by means of brackets 48, electromagnetic regulators 49 and 50 arranged so that their connecting fingers 51 and 52 in od into wasp-h stems grooves 53 and 54, respectively, formed in the rods 37 and 38 against the action of return springs 55 and 56. The apparatus operates in the following in particular: Zoom. If you want to make a normal lint-free cloth and therefore work with the bird always with a full surf, i.e. in the closed position, then two electromagnetic regulators 49 and 50 are needed only to keep them not excited so that their connecting fingers 52 and 53 are retracted by springs 55 and 56 from axial grooves 53 and 54 in rods 37 and 38 Thus, the control lever 41, by rotating the control cam 47 clockwise, reciprocates freely without acting on the rods 37 and 38 and, consequently, the vertical lever 30 has a protrusion 32 freely held by the spring 33 against the protrusion 34 i.e. in the configuration, which corresponds to the closed position Byrd. Rotation of the bat 11 around its axis 12 at the closed position, shown in Fig. 1, to the open position in the direction of the arrow causes connection 28 to move along the hole, but since it is an arc having its center on the rotational axis 12, as a result Connection 28 moves, through a path, the distance of which from rotational axis 12 remains constant. Obviously, relative rotation between the toothed sector 21 and the camshaft 22 does not occur, because of which the reed 15 always remains in the closed position for a full stroke of the bat. When it is necessary to create a terry cloth, the electromagnetic regulator 49 must be energized to attach the control lever 41 to the rod 37. Thus, rotating the control cam 47 in the direction of the arrow causes the control lever 41 to rotate counterclockwise, followed by the movement of the attached cam. rod 37 to the right, while the other rod remains free. As a result . The vertical swing arm rotates counterclockwise around the finger 31, whereby the aperture 29 becomes located, as shown by the dotted line 29 in Fig. 1, i.e. its upper end 29 located pr.direction to the rotational axis of the 12th baton. This arrangement of the hole 29 causes the levers 26 and 27 to move at a great distance from each other, the counterclockwise rotation of the toothed sector 24 detects the cam shaft 22. The counterclockwise rotation of the cam 21 determines the counterclockwise movement of the connecting levers, 20 and, therefore, the current of the pushers 17 so that the reed rotates clockwise around its hinge pins 19 and retracts to its open position, shown by the dotted lines 15 in FIG. In addition, during the initial stroke of the baton in the direction of the arrow, the joint 28 begins to move down the hole 29 and therefore passes through a trajectory, the distance of which increases from the rotational axis 12 in the direction from the upper end of the hole to the lower one. As a result, the toothed sector 24 and the camshaft 22 are rotated clockwise, the connecting levers 20 move to the right and the reed 15 rotates clockwise, which moves it to the open position when the bat 17 is at the end of the open reciprocating motion i.e. when the joint 28 reaches the lower end of the orifice, which as a result of everything has to occur, in order to prevent the reed from colliding with the frames 5 and damaging the helium, 4. Then the reed returns to its open position during the closed stroke of the bat, because connection 28 begins to move in the opposite direction along the opening 29. To change the pile height that is required for special weaving effects, it is necessary to turn off the electromagnetic regulator 49 to make the rod 37 free and turn on another electromagnetic regulator 50 in order to attach another rod 38 to the control lever 41, which can be done while the machine is moving. Taking into account that at a point lower to point 31, the lever transmits the swinging lever a counterclockwise rotation to a greater angle than that transmitted by another rod 37. This larger rotation of the swinging lever leads to a greater rotation clockwise of the reed, in a manner similar to that described in as a result, the reed is relegated to a greater degree to the normal open position shown by the dotted lines in FIG. The proposed batan mechanism provides high reliability and ease of operation.
