Definitions

  • This invention relates to a weft feeder for textile machines, particularly knitting machines, provided with an improved system for fixing the stationary drum onto the motor housing.
  • weft feeders for knitting machines comprise a stationary drum on which a swivel arm, driven by a motor, winds multiple loops of thread, which constitute a weft reserve.
  • the motor shaft is hollow, so that the thread can pass within it; the thread then exits through a slot provided at an intermediate section of the shaft and is sent to a guide located at the end of the swivel arm for winding on the drum.
  • the loops of thread unwind from the drum and are supplied to the loom after passing through a braking means that controls the mechanical tension of the thread in order to maintain it substantially constant.
  • a device for fixing the drum to the motor housing having two complementary frustum-shaped rings on which permanent magnets with mutually opposite polarities are agglomerated, one ring being attached at the end of the motor housing, the other ring being attached to the drum.
  • EP-A-0 525 906 describes a device for forming a yam coil from a yam supplied from a yam package, in which a winding drum is floatingly mounted in a support frame, with a winding member that is pivotally supported therebetween to wind the yam onto the drum.
  • the supporting frame and the drum are provided with embedded magnets which are disposed to lie opposite to one another in the rest position of the drum.
  • the magnets are surrounded by an electrically conductive material, e.g. in form of rings or plates also embedded in the material of the frame or drum.
  • US 4, 614, 311 describes a yarn storage and delivery apparatus, in which a yarn wrapping member and a yam winding drum are rotated in opposite directions by motor means to wrap the yam around the yam winding drum.
  • a first set of permanent magnets are fixed to the drum, and a second set of permanent magnets are fixed to the structure in front of the first set of magnets, so that a magnetic attraction force is generated between the opposite permanent magnets, which force prevents the drum from rotating.
  • the magnets are shown as embedded in the material of the drum or structure.
  • the above devices for fixing the drum to the motor housing have drawbacks, the first of which is that, for example due to temperature variations that occur during molding operations, or due to impacts during assembly/disassembly and maintenance of the device, the magnets may break, be damaged or be partially demagnetized; such accidents necessarily cause replacement of the entire ring, with attendant penalties concerning maintenance times and costs.
  • the main object of this invention is therefore to provide a weft feeder equipped with a system for securely fixing the stationary drum to the motor housing, while allowing, in case of damage or incorrect assembly of some of its parts, the replacement of the damaged parts only.
  • Another object of the invention is to provide said device so that the system for fixing the drum to the motor housing has a smaller bulk and weight than known systems.
  • Another object of the invention is to provide said device so that it can be manufactured easily and at a low cost, by means of equipment that is conventional in the field.
  • a generic weft feeder generally designated by the reference numeral 10, comprises a motor housing 11 and a stationary drum 12, on which a frustum-shaped circular swivel arm 13, keyed on a motor shaft 14 driven by a motor M, winds multiple loops of thread F, which constitute a weft reserve RT.
  • motor shaft 14 is hollow, so that thread F can pass through it; the thread exits through a slot 15 provided at an intermediate section of shaft 14, and is sent to a guiding hole 16 provided in a peripheral region of the disk that constitutes the arm 13 in order to be wound onto the drum 12.
  • the loops unwind from drum 12 and are fed to the loom, passing through a braking means 17 that controls the mechanical tension of thread F in order to keep it substantially constant.
  • the fixing system has a set of first permanent magnets, such as 18a, which are detachably received in respective first recessed seats such as 19a, provided with a ferromagnetic plate 21a on their bottoms and arranged on a first annular surface 26 which is concave and frustum-shaped and is formed coaxially at the end of motor housing 11.
  • each of the ferromagnetic plates 21a is attached by means of a screw 25a to the first annular surface 26 and is provided with a rim 22, forming the edge of the resting surface of the magnet, in order to retain a bushing 23 made of plastic material, which has, for this purpose, a corresponding inside edge 24 at one axial end, shaped to surround the respective permanent magnet 18a.
  • Second permanent magnets such as 18b, having opposite polarities, are arranged opposite the first magnets and are also received in respective second seats such as 19b, provided with ferromagnetic plates 21b on their bottoms and arranged on a second annular convex frustum-shaped surface 20, which is complementary to surface 26 and is formed on a support 27 which is attached to the base of drum 12.
  • the second seats are preferably formed as cavities 19b made in the second annular surface 20; the ferromagnetic plates 21b are attached to the bottoms of said cavities by means of screws 25b.
  • Elongated centering brackets such as 35 and centering/attaching brackets such as 36 extend from support 27, parallelly to axis H, and receive nuts 37 which allow drum 12 to be connected to support 27 by means of screws 38.
  • Swivel arm 13 is keyed to the motor shaft 14 so that its hub 28 is sandwiched between the internal rotating rings of bearings 29, 30a, 30b, which themselves abut on shoulders 31, 32, respectively.
  • Bearings 29, 30a, 30b are received in seats 33, 34 formed respectively within the motor housing 11 and on the internal cylindrical surface of the support 27.
  • Neodymium magnets 18a, 18b are particularly suitable for the purposes of the present invention, since they possess, for equal sizes, a magnetic capacity up to ten times greater than the more commonly used ferrite magnets.
  • a steady connection of the parts is obtained, while a free volume is left between them as required for the passage of the swivel arm and the winding of the thread onto the drum.
  • Ferromagnetic plates 21a and 21b therefore perform the dual function of retaining the respective magnets 18a, 18b in their seats and of conveying their lines of flux into the region of interest where arm 13 rotates.
  • the invention fully achieves the intended aim, by providing a weft feeder having a system for securely attaching the drum to the motor housing, which system also allows each individual magnet to be replaced quickly and independently in case of damage or incorrect assembly, while complying with the required alternation of the polarities. Therefore, with the device according to the invention it is possible, if case of break of a magnet, to recover the remaining ones, with obvious cost advantages.
  • Another advantage of the device according to the invention is that it has a smaller bulk and a lower weight than known devices, the high magnetic capacity of neodymium being exploited not only for securely attaching the magnets to the respective seats and for achieving a more stable connection between the drum and the motor housing, but also for reducing the number and sizes of said magnets.
  • Another advantage of said device is that it has a low manufacturing cost and is simple to manufacture by means of equipment that is common in the field.
