Definitions

  • the invention relates to a control and guiding device, in particular for containment and knock-off boards in stitch-forming textile machines, with guiding means having guiding channels, in the guiding channels of which the at least longitudinally displaceably mounted boards are laterally guided over at least part of their length, and with a device which produces the longitudinal movement of the boards Drive device which has control surfaces which engage parts of the boards and extend essentially transversely to the guide channels and by means of which the boards can be given a longitudinal movement as a function of a relative movement between the control surfaces and the guide channels.
  • the invention also relates to a containment and knock-off board for stitch-forming textile machines, the devices for coupling to at least one control surface of at least one longitudinal movement thereof issuing drive device.
  • sinker lock generally has lock channels delimited laterally by control surfaces, into which a control foot arranged on a shaft part of the sinkers engages, but embodiments are also known in which the sinkers have an open groove in their shaft region into which raised control curves of the sinker lock protrude .
  • the control surfaces on the circuit board shaft not only exert a driving force component pointing in the longitudinal direction of the circuit board, but also a lateral force component acting transversely to their longitudinal direction, which results from the fact that the Move control surfaces substantially transversely to the guide channels containing the circuit boards.
  • the boards are not only pressed onto the side walls of their guide grooves on one side, but because of the lateral play in the guide grooves required for their easy mobility, they are also rotated somewhat about their longitudinal axis, ie tilted sideways.
  • the circuit boards perform their uncontrolled movements superimposed on their longitudinal movement, taking it under unfavorable conditions can even lead to jamming of individual boards in their guide channels. Since the sinker head, which is involved in the stitch formation, with its tapping edge, the throat and the trapping nose follows these uncontrolled movements, the thread tension is influenced during the stitch formation, which in turn can lead to an uneasy stitch pattern and streaking in the goods. When processing sensitive yarn, even thread breaks, especially in the stitches, can occur in the curling area.
  • the object of the invention is therefore to remedy this situation and to point out a way which allows Irregular movement conditions in the area of the part of the enclosing and tapping plates assigned to the stitch formation, resulting from the transverse forces exerted by the plate lock parts on the control elements of the plates, can largely be switched off and, at the same time, the noise and heat development occurring during the plate movement can be reduced.
  • the control and guide device mentioned at the outset is characterized according to the invention in that the boards are formed in two parts with a work part assigned to the stitch formation and a control part assigned to the control surfaces, of which at least the control part is guided in a respective guide channel, and that are connected to one another in a limited manner such that the two circuit board parts can be rotated relative to one another about an axis extending essentially in the longitudinal direction of the guide channel.
  • the rotatable connection of the two board parts can be solved in different ways.
  • Embodiments are also conceivable in which a twistable connecting element is arranged between the two circuit board parts, which consists of a material that is particularly suitable for this purpose, for example plastic or the like, or is formed by a corresponding cross-sectional taper in the area between the two circuit board parts.
  • the control and / or the working part of the board can have recesses or recesses in order to reduce the inertial mass and possibly the friction surface or to improve the sliding and guiding conditions.
  • at least one of the circuit board parts can advantageously have at least one open-edge recess facing the base of the guide groove.
  • the arrangement is advantageously made such that the two parts of the board are pivotably connected to one another to a limited extent, while the drive device is connected to it
  • Working part can be brought into engagement and has a swiveling or tilting movement about a transverse pivot axis control means.
  • the working part can have at least one integrally formed control element which can be brought into engagement with control surfaces of the control means.
  • the working part can be brought into or out of engagement with the control surfaces of the control means by means of a longitudinal movement imparted to it by the control part, or it can be achieved by appropriate design of the control means and the articulated connection mentioned between the two circuit board parts the working part can be designed to be pivotable or tiltable independently of the longitudinal displacement movement.
  • the pivoting or tilting movement of the working part is inevitably derived from the longitudinal movement of the plate
  • the working part in the second alternative the working part can be pivoted or tilted independently of the position reached in the course of the longitudinal movement.
  • the above-mentioned containment and knock-off board itself is accordingly characterized in that it is formed in two parts with a work part assigned to the stitch formation and a control part assigned to the control surfaces, and that the two board parts are substantially in the longitudinal direction of the work and / or the control part extending axis are rotatably connected to each other.
  • control and guiding device and the containment and knock-off board are the subject of subclaims.
  • the concept according to the invention is not specifically limited to containment and knock-off boards, but is generally suitable for knitting tools which are longitudinally displaceable or pivotable or tiltable and which are given a drive movement by a relative movement of essentially transverse control surfaces and which are thereby related to their longitudinal movement direction , are exposed to transverse force components that endeavor to tip the knitting tool in the guide groove or to press it on one side onto the side walls.
  • Fig. 1 of a so-called smooth circular knitting machine with a row of needles only the parts essential for stitch formation are illustrated in the detail. The basic structure of such a machine is known and therefore need not be explained in detail.
  • axially parallel webs 2 are inserted at a distance, which delimit guide grooves between them, in which latch needles 3 are guided so as to be longitudinally displaceable.
  • the needle lock parts controlling the longitudinal movement of the latch needles 3 are not shown.
  • a sinker ring 4 Surrounding the needle cylinder 1 at a distance is a sinker ring 4, which is structurally connected to the needle cylinder 1 in a manner not shown in more detail and has milled, on its upper side, radially extending guide grooves which form guide channels 5, which laterally through webs 6 running between the guide channels 5 are limited.
  • a sinker lock disk 7 which is coaxial with the needle cylinder 1 and the sinker ring 4 and which has a sinker lock channel 8 which is laterally delimited by control surfaces 9 in a manner known per se.
  • the guide channels 5 of the sinker ring 4 are generally used with 10 designated enclosing and knock-off boards, each of which carries a control foot 11, which in the Circuit board lock channel 8 protrudes and interacts with the control surfaces 9.
  • Each containment and tee board 10 is formed in two parts; it consists of a control part 12 and a working part 13.
  • the control part 12 essentially comprises the platinum shaft with the upper and lower edges of the shaft parallel to each other as well as the control foot 11 molded onto it and the so-called tracking 14, i.e. in cooperation with the control surfaces 9 the elements generating the drive movement of the board.
  • the working part 13 contains the elements required for forming a stitch, namely an inclusion groove 15, an adjoining knock-over edge 16 etc. and a shaft part 17 which is of a rectangular cross-section and matches the dimensions of the control part 12, with which the working part 13 in the associated guide channel 5 is guided laterally.
  • the two circuit board parts 12, 13 are arranged abutting one another on the end face and positively connected to one another at a connection point 180.
  • the control part 12 has an essentially part-circular end face limited projection 18 is cut, which is inserted into a correspondingly partially circular recess 19 in the region of the end face of the working part 10.
  • the longitudinal axis 21 extends parallel to the bottom surface of the respective guide channel 5; in the exemplary embodiment shown, it is the longitudinal axis of symmetry of the control part 12 and at the same time the shaft part 17 of the working part 13. It runs centrally through the projection 18.
  • connection point at 180 is indicated only schematically, without the structural details:
  • the transverse rotation 22 between the sinker ring 4 and the sinker lock disk 7 exerts transverse forces 22 directed approximately at right angles to the guide channels 5 on the control foot 11, which push the control foot 11 aside, via the essentially transverse control surfaces 9. Because of the operationally necessary lateral play between the side walls 23 of the guide channel 5 and the flanks of the shaft part of the Enclosure and knock-off board 10 is thereby not only tilted somewhat of the board shaft about the longitudinal axis 21, but also pressed laterally against the side walls 23 of the guide channel 5, as exaggeratedly illustrated in FIG. 6 for the sake of clarity.
  • the transverse forces 22 can only tilt the relatively short control part 12 in the manner described and press it against the guide channel side walls 23.
  • the "rotary coupling" at the connection point 180 prevents this tilting movement from being transmitted to the working part 13, which can thus carry out its longitudinal movement imparted to it by the control part 12 in the guide channel 5 without hindrance and in the correct position.
  • the result of this is that the elements 15, 16 involved in the stitch formation and arranged on the board head of the working part 13 do not perform any uncontrolled movements, as would otherwise be triggered by the transverse forces 22.
  • the friction occurring between the guide channel side walls 23 and the containment and knock-off boards 10 is essentially limited to the relatively short control part 12; the shaft part 17 of the working part 13 is not laterally loaded by the lateral forces 22 because of the play 20 in the connection point 180.
  • the described division of the enclosing and tee-off boards 10 into a control part 12 and a working part 13 is particularly also for those knitting machines of importance in which the containment and knock-off sinkers not only perform a longitudinal movement, but additionally also a transverse pivoting or tilting movement, as described, for example, in DE-PS 31 08 041.
  • FIGS. 3 to 5 Exemplary embodiments of the control and guiding devices on such machines, which are designed using the principle described with reference to FIG. 1, are illustrated in FIGS. 3 to 5. 1, 2 and 6, the same parts are provided with the same reference numerals and are not explained again.
  • sealing and knock-off boards 10a, b, c are alternately guided in a longitudinally displaceable manner with the latch needles (not shown in FIGS. 3 to 5).
  • a stationary blank lock jacket 24 Coaxial to the revolving needle cylinder 1 is a stationary blank lock jacket 24, on the inside of which blank lock parts 25, 26 are fastened, of which the blank lock parts 25 in turn delimit a blank lock channel 8a with control surfaces 9a, which cooperates with the control feet 11a of the enclosing and knock-off boards 10a.
  • Each containment and tee board 10a is again formed in two parts with a control part 12a and a working part 13a; both board parts 12a, 13a are provided with openings 27 through which their inert mass is reduced. Open-ended recesses 28 of the control part 12a reduce the sliding surface on the bottom of the guide channel 5 or on the circuit board lock part 25.
  • the working part 13a having the throat 15a and the tapping edge 16a is in turn connected at 180 to the control part 12a so as to be rotatable to a limited extent about the longitudinal axis 21.
  • the positive connection is, similar to that according to FIG. 1, formed with the circular projection 18a and the corresponding recess 19a and therefore not to be explained further.
  • the projection 18a could also be spherical, the recess 19a then being designed in the manner of a ball socket.
  • connection point 180 forms at the same time an articulation point with a pivot axis, indicated at 29, at right angles to the plane of the drawing, which intersects the longitudinal axis 21 forming the longitudinal symmetry axis of the control part 12a, which at the same time is the longitudinal symmetry axis of the shaft part 17a of the working part 13a.
  • a control lug 30 is formed on the shaft part 17a on the side facing the needle cylinder 1, which control lug is assigned to a projection 31 formed on the opposite side and cooperates with a conical control surface 32 arranged all round on the needle cylinder 1. In a corresponding manner, the projection 31 interacts with a likewise conical control surface 33 of the board lock element 26.
  • the arrangement in the embodiments according to FIG. 4.5 is such that the pivoting. of the working part 13b or 13c is independent of the position reached in the guide groove of the needle cylinder 1 in the course of the longitudinal displacement movement.
  • the working part 13b is provided on its side facing the lock shell 24 with two spaced lugs 30b, each with its own, on the lock shell 24 inside attached board lock parts 26b and c cooperate, which only control the pivoting movement of the working part 13 about the transverse pivot axis arranged at 29.
  • the pivot axis 29 lies in the middle between the two lugs 30b and c on the opposite side, such that it is arranged laterally on the shaft part 17b and 17c of the working part 13b and 13c.
  • the connection point 180 between the working part 13b or 13c and the control part 12b or 12c with the control foot 11b or 11c is designed similarly to the embodiment according to FIG. 3; the circular or spherical projection 18b or 18c allows in the circular or spherical recess 19b or 19c, in addition to the tilting movement about the pivot axis 29, a limited rotatability between the two board parts 12b or c and 13b or c, by the through the pivot axis 29 longitudinal axis 21.
  • the lock elements controlling the longitudinal movement of the sinker are designated by 25; the control surfaces delimiting the lock channel 8b or 8c are designated 9b or 9c.
  • control surfaces 32b, 33b and 32c, 33c which are arranged on the circuit board lock parts 26b and 26c and are in engagement with the lugs 30b and c, run in the form of closed curved surfaces on the inner peripheral surface of the annular circuit board lock elements 26b and 26c. They have areas of different radial distances from the needle cylinder axis and are otherwise designed in the axial direction with a width such that an unobstructed longitudinal displacement movement of the working parts 13b and 13c is possible.
  • the limited rotatability of the two circuit board parts 12, 12a, 12b, 12c and 13, 13a, 13b, 13c against one another is given in that the two parts are positively connected to one another at the connection point 180 in the manner described, with play.
  • a twistable element is provided at the junction 180 for connecting the two circuit board parts, which element consists, for example, of plastic, etc. and is connected at the end face to the two circuit board parts.
  • Such an element is indicated schematically in FIG. 6 at 40. It could also be formed by a circumferential, groove-like cross-sectional reduction of the platinum shaft, in such a way that the connecting element, indicated cylindrically in FIG.
  • the thread support surface of the working part 13a containing the knock-off edge 16a is oriented essentially flat and at right angles to the axis of symmetry of the working part 13a.
  • the thread support surface can be curved in a substantially circular manner, as is indicated by dashed lines in FIG. 3.
  • the center of curvature is preferably on the pivot axis 29, but it can also lie somewhat next to this pivot axis. In this way, a relief of the thread lying on it can be achieved when the working part 13a is swiveled.
