    Control device for adjusting the radial position of the sinkers in a circular knitting machine, constituted by a couple of cams for the radial drive of the sinkers, co-planar and concentrical with the axis of the cylinder and substantially circular, the innermost of which is stationary, and the outermost of which is radially approached and pushed away due to the effect of a countercam (17) externally placed around it, provided with approach and pushing-away lengths, which, by means of its discrete revolution, radially approaches it, and pushes it away.

    The invention relates to a device for adjusting and controlling the position of the plates of a circular machine, in particular, for adjusting the radial position of the plates in machines equipped with devices for changing the density of the finished fabric by axial displacement of the ring set of plates in which the interacting with gshatinami for forming loops of hooks collected yarn.
    The purpose of the invention is to simplify the design and improve the quality of the manufactured product.
    FIG. 1 shows a ring with cams mounted on it; Fig. 2 is a diagram of the positioning of the cam relative to the counter cam corresponding to the long loop; in Fig „3 - the same, corresponding to the short loop; Fig. 4 is a diagram of a circular die machine with a kinematic transmission controlling the rotation of the circular anti-cam; on Fig 5 - anti-cam, top view; in fig. 6 is a diagram of the kinematic gear with bevel gears, side view; Fig. 7 is a diagram of the interaction of needles and platinum in obtaining long loops; Fig 8 - the same, when receiving short loops

    To obtain the desired tension, the platinum loops are mounted with the possibility of moving along the radius (Figo 7 and 8) due to their installation on the ring-shaped bottom support 1 with radial slits inside which platinum 2 are installed with the possibility of radial reciprocating movement
    In the upper part of platinum 2, two vertical protrusions 3 and 4 are made, which alternately interact with cams 5 and 6 mounted on the upper support 7, having the form of a ring, the contour of cams 5 and 6 is shown in FIG.
    The inner cam 5 is made almost at the same time with the support 7, t0e „attached to it with screws 8, the outer cam 6 is divided into a number of sections and attached to the support 7 with pins 9 installed in larger holes 10 that allow radial movement of the cam to a certain stroke length. A circumferential passage of the spring 11 creates a small force on the section of the outer cam 6, the sense of his vision. However, the force generated by this spring, directed radially inward, should not exceed the strength of the yarn to break, and when the hook 12 t is not yarn 13 outward and acts on the recess 14 of the platinum 2, an outwardly directed spring-exerting force, the spring must be able to tolerate the removal of platinum,
    The spring 11 pushes the recess 14,, platinum inward to a distance that the yarn 13 allows, therefore, the yarn 13 is permanently tensioned, which eliminates slack loops
    When receiving long loops of platinum, they act on the upper level A (fkgo 7), when receiving short loops of platinum they act on the lower damage B (Fig “8) o
    In the operating mode of the machine, the cylinder rotates, and with it the platinum-bearing assembly, and the cam 6 or precisely the contour parts of it under the action of centrifugal force created by platinum are pressed by the projections 15 to the anti-cam 16 "Adjusting the cam's 6 position is 3d score nosopotd protivokuvachka 16 along arrow R at a certain angle relative to the center C, lying

    on the cylinder axis. Such a rotation allows the section opposite the projections 15 to be brought closer to the center C, and depending on this section the cams 6 either move inwards or are retracted.
    In the diagrams (FIGS. 2 and 3), index A denotes the position corresponding to the long loop, Tov „to advance the plates inwards for a longer distance, and index B to denote the position corresponding to the short loop, t“ in the outlet of plates to the outside tion ,.
    The rotation R from the position of the minimum advancement of the cam 6, and consequently, the platinum inward radially to the position of maximum advance inward radially, is converted by means of known means, for example kinematic transmission with bevel gears, to a movement of the plane of platinum, t. points 14, respectively, at the minimum and maximum level from Such a kinematic transmission is shown in FIG. 4-6.
    The lifting of the slotted cylinder-holder of the hooks, and with it the circular support 1 supporting platinum 2, is carried out using a plate 17 rotatably mounted about an axis 18 in accordance with the kinematic scheme of the known device. Raising the circular support 1 allows the loops formed by the engagement of the hooks 12 and platinum 2 to lengthen with simultaneous raising and lowering of the cylinder-holder of hooks caused by the rotation of the plate 17, its movement in the axial direction is transmitted by the rod 19 moving along the arrow A 0
    The rod 19 is integral with the lever 20, which moves while remaining parallel to itself, with respect to the fixed frame 21, together with a pin 22 passing through the slot 23 in the support 21 "
    The movement of the lever 20 is transmitted by the adjustable pusher rod 24 to the lever 25 mounted on the hinge axis 26 to rotate in arrow B, the bevel gear 27 rotates with the axis 26 and rotates the bevel gear 28 BV in the direction C "The lower end of the hinge axis 29 is made integral with the bevel gear 28, and its upper end is connected to the lever 30, which by
    The forked end 31 engages the pin 3., which is integral with the anti-cam 16, and provides the indicated rotation R; The through hole 33 at the other end of the lever 30 through the clip 34 allows the lever 30 to be locked on the rotating axis 29
    Constant contacting of the lever 20 with the push rod 24 is provided by the spring 35,
    The proposed device allows you to smoothly and precisely install all parts of the cam contour due to the rotation of a single receiving element and does not require the use of many complex elements that need to be coordinated and controlled.
