Definitions

  • the present invention relates to the single-cylinder knitting machine, and more in particular to the single-cylinder knitting machines with latch needles.
  • the invention also relates to a needle cylinder for a single-cylinder circular knitting machine.
  • Single-cylinder knitting machines are provided with a single circular needle bed formed by needles sliding in tracks provided in a needle cylinder.
  • the needles cooperate with a ring of sinkers provided with an alternating radial movement synchronized with the downward and upward movement of the needles.
  • a knitting machine without sinkers is disclosed in WO-A-2007/074486 .
  • the stitch is formed on a stitch-forming plane or surface comprised of components attached to the upper end of the needle cylinder, i.e. to the end in correspondence of which the needle hooks are arranged, which are cyclically extracted and retracted to take the yarn and form stitches.
  • tabs projecting between adjacent needles. These tabs are usually produced by machining a cylinder blank.
  • the function of these tabs is to replace the movable sinkers defining the position of the stitch forming plane or surface that, unlike what occurs with movable sinkers, is fixed, i.e. without radial movement.
  • the yarn always rubs on a fixed position on the tabs, thus causing premature wear of the upper edge of these tabs with a cut that could worsen the features of the produced fabric and facilitate yarn breakage.
  • the tabs forming the stitch forming surface are firstly formed by chip removal from the cylinder blank and then hardened through an induction hardening cycle.
  • this does not solve the problem in a satisfactory manner.
  • the hardened tabs are fragile and can break more easily following an impact. Their surface finishing does not allow the yarn to slide in an optimum way. Moreover, the tabs shall be produced with a much reduced thickness to leave sufficient space between them for the movement of the needles and the passage of the yarn during stitch formation. Thin tabs are even more subject to break due to the fragility resulting from the hardening process.
  • the production of the tabs with a material other than that of the cylinder has been proposed, producing the tabs as separate elements, adequately shaped and then glued in cuts formed by milling in the edge of the needle cylinder. In this way the inserts can be produced in the more suitable material, with the necessary hardness and optimum surface finishing.
  • a single-cylinder knitting machine comprising a needle cylinder and a plurality of latch needles sliding in respective tracks of the needle cylinder.
  • the invention also relates to a cylinder for circular knitting machines.
  • an annular channel with an undercut is advantageously provided along one end of the needle cylinder.
  • a substantially radial respective groove is provided, formed in the needle cylinder and intersecting the annular channel.
  • a respective insert can be housed in each groove.
  • the various inserts form with their respective upper edges a stitch forming surface or plane, i.e. a sinker surface.
  • Each insert can have an appendix that is inserted and blocked in the undercut of the annular channel.
  • a blocking element holds the inserts in a working position in their respective grooves.
  • the appendices of the inserts are advantageously pushed in the undercut of the annular channel by the blocking element, so as to maintain the inserts fixed during the knitting process, preventing the inserts from exiting the grooves.
  • the blocking element By removing or deactivating the blocking element, one or more inserts can be removed and replaced, for instance when worn or damaged.
  • This operation can be done by a machine operator, without the need for transporting the machine to a workshop, thus making the use and maintenance of the circular knitting machine much easier.
  • the blocking element pushes the inserts in a substantially radial direction. Depending upon the position of the undercut, this thrust may be radially inwards or radially outwards.
  • the thrust exerted by the blocking element is preferably a resilient thrust, so as to balance any dimensional tolerance and facilitate removal and replacement of the inserts.
  • the substantially radial grooves, wherein the inserts are housed have a depth smaller than the depth of the annular channel, so that along one flank of the channel a continuous surface forms, defining the undercut, with which the inserts cooperate.
  • the undercut is delimited by a surface that is inclined towards the bottom of the annular channel, for instance a surface shaped like a solid of revolution, typically for instance a conical surface.
  • the appendices of the inserts can project from a lower edge of the insert, which edge is opposite with respect to the upper edge defining the stitch forming surface.
  • the appendices can advantageously have an inclined edge, forming with the lower edge an angle lower than 90°, for instance comprised between 80° and 20°, and preferably between 70° and 30°.
  • Figure 1 shows a cross-section of the upper part of a needle cylinder in a single-cylinder circular machine according to a nearly radial surface according to I-I in figure 2 , which in turn shows an enlargement of a portion of the needle cylinder in a front view according to II-II of figure 1 .
  • reference number 1 indicates the needle cylinder and reference number 3 indicates one of the latch needles, the needle cylinder 1 is equipped with.
  • needles 3 are arranged in a number corresponding to the fineness of the machine around the whole circular extension of the needle cylinder 1.
  • each needle 3 slides in a respective track 4 substantially parallel to the axis A-A of the cylinder.
  • each track where the needles 3 slide can be formed by milling of the cylindrical surface of the needle cylinder 1.
  • each track is defined by two adjacent and consecutive bars 5, extending parallel to the axis A-A of the needle cylinder 1 and fixed in corresponding grooves provided in the needle cylinder 1. Some or all the bars 5 can be provided with feet 5A for the purposes described below.
  • the needles 3 can be provided with butts 3T cooperating with control cams arranged in a cam mantle, not shown and arranged around the needle cylinder 1, as well known to those skilled in the art.
  • the needles 3 can be held in the tracks by means of annular springs 7.
  • the needle cylinder 1 has an upper end or edge 1A along which an annular channel 9 is provided, extending along the entire circular extension of the needle cylinder 1.
  • Upper end means the end at which are arranged and from which exit the hooks of the needles 3 during the knitting process (see sequence of figures 5A to 5L ).
  • the channel 9 has a bottom surface 9A, for instance flat and laying on a plane orthogonal to the axis A-A of the needle cylinder 1.
  • 9B and 9C indicate two flanks, respectively the radially inner and the radially outer flank of the channel 9.
  • the flank 9B has a substantially cylindrical extension
  • the flank 9C has advantageously an axial-symmetrically shaped surface portion, in particular a surface of revolution around the axis A-A.
  • the surface portion in question has a substantially conical shape flared downwards, i.e. towards the bottom 9A of the channel 9, and is coaxial with the needle cylinder 1.
  • the surface defining the flank 9C is shaped so as to define an undercut 9D inside the channel 9.
  • substantially radial grooves 11 are provided along the upper end 1A of the needle cylinder 1.
  • the radial grooves 11 intersect the annular channel 9.
  • a radial groove 11 can be provided in correspondence of each bar 5 delimiting a corresponding track where the needles 3 slide.
  • two substantially radial grooves 11 are therefore provided, arranged at the side of the track where the needle slides.
  • each groove 11 an insert 13 can be inserted, shown separate from the cylinder in the upper part of figure 3 and mounted in the groove 11 in figure 1 .
  • each insert 13 can have a substantially laminar shape with variable thickness. More in particular, an upper portion 13A of the insert 13 has a thickness S1 lower than the thickness S2 of a lower portion 13B of the same insert 13.
  • the lower, thicker part 13B is integrally housed in the radial groove 11 while the thinner part 13A is partially housed in the radial groove 11 and partially or completely projecting there from.
  • the thickness of the insert 13 is constant along the whole height, or can vary continuously from a maximum to a minimum thickness.
  • the configuration of figure 4 is particularly advantageous, as simple to be produced and particularly robust and effective.
  • the thicker part is an optimal guide in the groove 11 and increases the mechanical resistance of the insert.
  • the thinner part leaves more space for the yarn in the stitch forming step, when the needle arranged between two adjacent inserts 13 goes down below the stitch forming surface.
  • each insert 13 has an upper edge 15 ( figure 3 ) and a lower edge 17, in as well as two side edges or flanks 19 and 21.
  • “Upper” and “lower” refer to the position that these inserts normally take when mounted on the needle cylinder 1 and this latter is positioned in the most frequent vertical position, with the edge 1A facing upwards. It is also possible that the needle cylinder 1 is positioned in a different manner.
  • the inserts 13 When mounted in their grooves 11, the inserts 13 form, with their respective upper edges 15, a stitch forming or sinker surface.
  • the upper edges 15 of each insert 13 may have a first portion 15A inclined from the top downwards and from the outside towards the inside of the needle cylinder 1, and a second portion 15B radially more external with respect to the first portion 15A, with a substantially horizontal extension, i.e. orthogonal to the axis A-A of the needle cylinder 1 when the insert 13 is mounted in the respective groove 11.
  • the inserts 13 may be provided with a wear-resistant coating or treatment. In particular, according to particularly advantageous embodiments, the wear-resistant coating or treatment may be limited to the portion 15B.
  • each insert 13 has an appendix 23 projecting from the lower edge 17 opposite to the edge 15.
  • the insert 13 engages the respective appendix 23 in the undercut 9D formed by the flank 9C of the annular channel 9.
  • the appendix 23 may have advantageously an inclined edge 23A, with an angle corresponding to the opening angle of the conical surface 9C delimiting the undercut 9D of the annular channel 9.
  • a blocking element 31 is provided for holding each insert 13 inside the annular channel 9 with the respective appendix 23 engaged in the undercut 9D.
  • the blocking element 31 may comprise a ring 33 associated with the needle cylinder 1.
  • the ring 33 may be housed in an annular seat 35 with which the needle cylinder 1 is provided and which is arranged in a position radially more internal and substantially concentric with respect to the annular channel 9.
  • the ring 33 may advantageously have a pushing surface 37 cooperating with the inserts 13 so as to push the inserts 13 radially outwards so as to push the appendices 23 of the inserts 13 in the undercut 9D, bringing the inclined edges 23A against the conical surface of the flank 9C of the annular channel 9.
  • the pushing surface 37 has a substantially conical shape diverging upwards.
  • the conical surface 37 cooperates with the radially more internal side edge or flank 19 of each insert 13.
  • the radially more internal side edge 19 has an inclined portion, with an inclination angle preferably corresponding to the inclination angle of the conical pushing surface 37 of the ring 33.
  • the radial dimension of each insert 13 is such that the radially more internal side edge 19 of each insert 13 may project from the respective groove 11 radially towards the inside of the needle cylinder 1 when the inclined edge 23A of the appendix 23 is abutting against the inclined surface 9C defining the undercut 9D of the annular channel 9, as shown in figure 1 .
  • the ring 33 may be rigidly fixed to the needle cylinder 1 through screws in the seat 35.
  • the ring 33 of the blocking element 31 is mounted resiliently.
  • a ring of screws 39 is provided, engaging in threaded holes 41 provided in the bottom of the seat 35 of the needle cylinder 1.
  • Each screw 39 is inserted in a seat 33A of the ring 33 and a compression spring 43, for instance a helical spring, is interposed between the bottom of the hole 33A and the head of each screw 39.
  • a compression spring 43 for instance a helical spring
  • the inserts 13 cooperate with respective movable elements 51 housed in horizontal slide tracks 53 provided in a crown 55.
  • the crown 55 is mounted coaxially to the needle cylinder 1 and fixed to this latter for instance through the feet 5A of the bars 5 delimiting the sliding tracks of the needles 3.
  • the movable elements 51 are controlled so as to move with a reciprocating motion according to the double arrow f51 ( figure 1 ) by cams (not shown) cooperating with the throat 51A with which the movable elements 51 are provided.
  • Each movable element 51 has furthermore a finger 51B oriented radially inwards and superposed onto a respective insert 13.
  • the stitch formation with a circular knitting machine designed as illustrated in figures 1 to 4 occurs with the sequence illustrated in figures 5A to 5L .
  • the inserts 13 defining the stitch forming surface perform at least partially the function usually performed by the movable sinkers, with which the single-cylinder knitting machines are provided.
  • the movable elements 51 hold the stitch near the stitch forming surface defined by the set of the upper edges 15 of the inserts 13 when the needles are lifted, so that the stitch is not drawn upwards through the lifting of the needles and is pushed towards the center, maintaining it into contact with the needles.
  • each figure shows the stitch forming members and an enlargement thereof.
  • the needle 3 has brought the thread or yarn F below the stitch forming surface, here indicated with P and formed by the upper edges 15 of the inserts 13.
  • the needle 3 starts the upward movement, while the movable element 51 has moved radially inwards so that in the subsequent step ( figure 5C ) the finger 51B of the movable element 51 holds the yarn preventing it from being drawn upwards by the upward movement of the needle towards the position of figure 5D .
  • the upward movement of the needle continues ( figures 5E, 5F ) until the stitch is discharged from the opened latch 3L of the needle 3, and, held by the finger 51B of the movable element 51, remains adjacent to the stitch forming or sinker plane or surface P.
  • Figures 5G, 5H and SI show the movable element 51 translating radially outwards, the needle 3 with the yarn F moving downwards for forming the subsequent stitch, and the latch 3L of the needle 3 closing again until allowing the passage of the just formed stitch M above the hook 3U of the needle 3, as shown in figures 5J, 5K and 5L .
  • Figures 6 and 7 show a modified embodiment of the blocking systems for blocking the inserts 13 in the respective radial grooves 11. Equal or equivalent parts to those of the embodiments illustrated with reference to figures 1 to 4 are indicated with the same reference numbers and will not be described again.
  • the appendix 23 projecting from the lower edge 17 of the insert 13 has an inclined edge or flank 23A oriented radially inwards, and not outwards as in figures 1 to 4 .
  • the annular channel 9 has a substantially cylindrical, radially outer flank 9C and a radially inner flank 9B forming an undercut 9D.
  • the undercut 9D is formed by an axial-symmetrical surface with respect to the axis A-A of the needle cylinder 1, similarly to what is provided in the embodiment of figures 1 to 4 for the surface 9C.
  • the surface 9B may be conical.
  • the inclination of the conical surface 9B of the radially inner flank of the annular channel 9 substantially corresponds to the inclination of the edge or flank 23A of the appendices 23 of the single inserts 13, that in this embodiment is arranged on the radially inner side instead of being arranged on the radially outer side of the appendix 23.
  • the inserts 13 are mounted in the respective grooves 11 with the appendices 23 engaging the channel 9 and the undercut 9D of this channel. This position is ensured by a thrust oriented radially inwards rather than outwards, as in figures 1 to 4 .
  • the radial inwards push may be generated by a blocking element surrounding the needle cylinder 1.
  • the blocking element comprises at least one annular spring 61 engaging in an annular throat 63 provided in the needle cylinder 1 at the height of the grooves 11.
  • Each insert 13 may have a throat 22 along the radially outer edge 21. When the insert 13 is mounted in the respective groove 11, the throat 22 is arranged nearly in correspondence of the annular throat 63.
  • each insert 13 The dimension and the shape of each insert 13 are such that, when the inclined edge 23A of the insert 13 is in abutting contact with the conical surface 9B defining the undercut 9D, the profile of the throat 22 projects radially with respect to the bottom of the annular groove 63, ensuring in this way an effective resilient thrust of the annular spring 61 holding the single inserts 13 in place.
  • one or more inserts 13 may be replaced by removing the single inserts against the resilient force of the annular spring 61.
  • the inserts 13 are shaped with their upper edges 15, 15A, 15B so as to perform at least a part of the functions of a normal movable sinker, and cooperate with movable elements 51 for forming stitch according to what has been already described with reference to figures 5A-5L .
  • Figure 8 shows a further embodiment.
  • the inserts 13 are shaped like fixed sinkers that do not need radial movable elements for stitch formation.
  • equal or equivalent parts to those of the embodiment of figures 1 to 4 are indicated with the same reference numbers and will not be described again.
  • the methods for mounting and the opportunity of replacing the single inserts 13 are the same as in the embodiment of figures 1 to 4 .
  • a radially inwards oriented hook 16 projects from the upper edge 15 of each insert 13 and cooperates with the respective latch needle 3 and more in particular with the leading edge of the needle, i.e. with the edge oriented radially towards the outside of the needle cylinder 1, to hold the stitch during the upward movement of the needle, thus making the use of the movable elements 51 unnecessary.
  • Figure 9 illustrates an enlarged section of the upper part of the needle cylinder 1 with the respective inserts 13 in an embodiment similar to that of figures 1 to 4 , wherein the appendix 23 has an inclined edge 23A, whose inclination is different from the inclination angle of the flank 9C forming the undercut 9D of the channel 9. More in particular, the difference in inclination is such that the contact between the edge 23A and the surface of the flank 9C of the channel 9 is near the end of the appendix 23, i.e. nearer to the bottom 9A of the channel. In this way the insert 13 is blocked in an optimal way by abutting against the surface of the flared flank 9C of the channel 9 without the need for accurate machining and particularly stringent tolerances.
  • the same solution, with inclination angles different between flank of the channel and edge of the appendix 23 may be used also in other embodiments.
