Definitions

  • the bobbin core is ejected from the seat by tipping a bobbin receiving tube upon movement of the seat from an active or unwinding position toward a reserve position to receive a fresh bobbin.
  • Air passages through the seat communicate with a hollow of the core and facilitate pneumatic end retrieval of the yarn.
  • This invention relates to winding machines and, more particularly, to a holder for yarn packages.
  • yarn means any sort of strand material whether textile or otherwise
  • package means the product of a winding machine, whatever its form.
  • a lift member which is raised to displace the package from its pin
  • a discharge member in the form of a bobbin receiving tube
  • Both the lift and discharge members are cam operated during the rotation of the carrier.
  • a winding machine attendant drops the bobbin onto the seat in the reserve position and arranges the end of yarn in a suitable position for subsequent introduction into the winding operation.
  • the invention in brief, is directed to overcoming these difficulties and to providing a simplified and a more economical and serviceable mechanism, and particularly such mechanism providing automatic bobbin handling for winding machines.
  • a fresh bobbin As a fresh bobbin is called for, it drops through a tube and onto a seat which includes a magnet for magnetically coupling the bobbin to the seat and thereby effectively preventing lifting of the bobbin from the seat during subsequent yarn end retrieval and unwinding operations.
  • the core is slid off of the seat by tilting the tube.
  • Air passages are provided'through the seat to facilitate pneumatic recovery of the yarn end of a fresh bobbin from the hollow core.
  • Another object is to provide a new and improved yarn package holder which magnetically couples the package to the holder.
  • a related object is provision for facilitating removal of the bobbin from the holder.
  • Still another related object is provision for the passage of air intoa hollow core of the bobbin.
  • a further related object is provision for ejecting the bobbin core from the holder.
  • FIG. 1 shows an empty bobbin core 18, after unwinding of the bobbin at the 'active station, being ejected from its seat 16 by tipping the tube 14 to slide the core off of the seat whereupon it drops out of the tube to suitable receiving means (not shown).
  • a winding machine includes a lower, channel-shaped frame member 22 and thereabove a housing 24, only a small portion being shown at the top of FIG. I.
  • a vertical shaft 26 is suitably journaled on the channel member 22 and the housing 24 and has its lower end fixedly secured to a bevel gear 28 which mates with a pinion 30 intermittently rotated by a drive.
  • shaft 32 responsive to the usual control system of an automatic winding machine to index a fresh bobbin 12 into the active position.
  • Fixed to the vertical shaft 26 above the channel member 22 is a lower horizontal supporting arm 34 which carries a pairof the bobbin holding seats 16, one on either end of the arm.
  • Each seat 16 has a nonmagnetic pedestal 36 of nylon or similar material, suitably fixed at its lower end to the arm 34 with an upwardly facing socket 38 at its upper end.
  • This socket receives a cylindrical, permanent magnet 40 (note FIG. 3) which is fixed therein in any suitable manner, for example as by a screw 42 passing through a vertical hole 43 the magnet and into the pedestal 36.
  • the illustrated magnet 40 has four poles 44 extending upwardly from a base 46 and the top faces 48 of the poles 44 are preferably facially aligned in a horizontal plane so that a magnetic object resting on top faces 48 is magnetically coupled to the magnet 40.
  • FIG. I shows the bobbin holder moving between the reserve and active positions, when one of the seats 16 enters the reserve position a bobbin 12 is dropped through the tube 14, with automatically as through a chute or manually by a winding machine attendant.
  • a magnetic ring 92 (FIG. 1) such as steel, on the end of the bobbin core 18 drops onto an annular flange 94 diverging upwardly and outwardly from the top of a cylindrical neck 95 about the socket 38.
  • the ring 92 is guided onto the faces 48 of the magnet so that the ring 92, and therefore the core 18,is magnetically coupled to the magnet 40 which is part of the seat 16.
  • the inner portion of the annular flange 94 is just slightly larger than thering 92 to assure centering of the bobbin 12 on. the seat 16, and overlies the upper edge of the socket 38 and is substantially even with the top faces 48 of the magnet.
  • An upper, horizontal supporting arm 96 is fixed to the vertical shaft 26 for rotation therewith.
  • This arm is bifurcated at its outer ends 98 which have notches 100 to receive opposite horizontal pivot pins 102 of an annular collar 104.
  • the collar 104' is rigidly secured to the tube 14 and upon rotation from the active position to the reserve position an upstanding cam finger 106 of the collar rides across a depending lobe 108 of an upper cam 110 which is concentric with the vertical shaft 26 and fixedly secured to the winding machine housing 29, as by spacers 112.
  • the tube 14 is pivoted to slide the core ring 92 off the magnet 40, up the flange 94 and thus off of the seat 16.
  • a yarn package holder for a package having a core comprising. a support, magnetic seat means rigidly mounted on said support for receiving the core and magnetically, rigidly coupling the core to said support, and surface means extending generally transversely outwardly about said seat means for guiding the core.
  • a holder as set forth in claim 1 in which said surface means substantially encircles and divergesoutwardly from said seat means and therewith forms a generally dish-shaped receiver for guiding the core onto the seat means.
  • a holder as set forth in claim I in which said seat means includes a magnet, a receiver for said magnet, said receiverand said magnet having cooperating means for the passage of air through the receiver and magnet to the core.
  • a holder as set forth in claim 1 including package-handling means for removing the core from the seat, said handling means comprises a tube, and means mounting said tube for movement from a receiving position aligned with said seat means for guiding the core onto said seat means, to a discharge position out of alignment with said seat means for ejecting the core from the seat means.
  • a holder as set forth in claim 7 in which said tube is above said seat means in said receiving position for downward passage of said core through the tube and onto said seat means, and said seat means is vertically stationary and constructed for sliding movement of the core thereon as said tube to moves to said discharge position, whereby the core drops from the seat means and out of said tube.
  • a holder as set forth in claim 8 in which said core has a longitudinally extending passage therethrough and a magnetic ring concentrically secured to an open end of the core, said seat means includes a magnet having an upwardly facing face portion for facially receiving said ring, a nonmagnetic member having an upwardly opening socket receiving said magnet and having a surface substantially encircling and diverging upwardly from said face portion and therewith fonning an up wardly opening generally dish-shaped seat for receiving the ring, said surface where adjacent said face portion being substantially even with the face portion to facilitate said core sliding thereacross, and said member and said magnet having cooperating means for the passage of air through the member and the magnet and into the hollow of the core.
  • a yarn package holder for a package having a core comprising, a seat for receiving the core, said seat including retaining means for receiving and magnetically coupling the core to the seat and including magnetic means to receive the core, and said seat further; including a surface diverging outwardly from and substantially encircling said magnetic means for guiding the core, and said surface and said magnetic means forming a generally dish-shaped seat for receiving the core.
