Definitions

  • the changer includes a bobbin rake or rotatable table having pins extending either horizontally or vertically for supporting the individual bobbins.
  • the bobbins to be wound are supported by one or a plurality of rotatable bearing devices, the position of the bearing devices being rotatable by an angle of 180, 120 or less by means of a shaft. In such devices the desired positioning is effected either by means of a manually actuated lever or a magnetically actuated positioning motor.
  • the positioning motor usually receives its positioning pulses from a sensing means which is responsive to the change in circumference or weight of the wound bobbin; the change in position is usually carried out by transmitting the positional motor output through a multimember lever system to a rotating shaft.
  • the last member of the lever system finally transmits the change to the shaft by means of an eccentric head which grips the shaft of the bearing device by means of teeth or a cam.
  • the present invention eliminates the disadvantages mentioned above and simplifies the handling of a bobbin changer so as to decrease its handling time and thus increase productron.
  • a bobbin changer mechanism comprising support means, bobbin drive means and an arm which is movable with respect to the support means.
  • a bobbin holder including at least a first, second and third frictionally engaged bobbins, is fastened to a rotatable shaft which is secured by the arm; the bobbin holder is positioned and arranged so that the first bobbin engages the bobbin drive means and the second bobbin engages the support means.
  • a switching mechanism cooperable with the arm and the rotatable shaft is provided to establish dampening and clutching coupling therebetween and to rotate said shaft and bolder so that the second bobbin engages the driving means and the third bobbin engages the support means whereby a wound bobbin is changed and replaced with an empty bobbin.
  • the switching mechanism includes outer discs retained by a coupling flange secured to the arm and inner discs retained by a member secured to the shaft.
  • the outer and inner rings are forced in frictional contact and as a result provide clutching engagement therebetween.
  • the bobbin changer does not overshoot its takeup position during the changing operation and provides a smooth bobbin change that allows exact thread exchange between the full and empty bobbin.
  • bobbin-gripping members are "provided on the inner surfaces of the bobbin changer for elastically receiving and frictionally holding via a spring box mechanism the first, second and third bobbins.
  • FIG. 1 is a top view of the bobbin changer of the present invention
  • FIG. 2 is a cross-sectional view taken along lines 2-2 of FIG. 1;
  • FIG. 3 is an enlarged cross section taken along lines 2-2 of FIG. 1;
  • FIG. 4 is a sectional view taken along lines 4-4 of FIG. 3;
  • FIG. 5 is an enlarged longitudinal section of the elastic bearing of the receiving plate utilized in the bobbin changer of FIG. 1.
  • a bobbin changer mechanism 10 including a generally looped bobbin arm 11 which is fixed to a U-shaped holder 12 by means of adjustable screws l4, l5, 16.
  • the holder 12 is solidly supported by a horizontal shaft 17 fixed to a base plate 19 by means of standing bearings 20 and 21 and accordingly is free to pivot about the axis of the shaft 17 such that the movement planes of the two legs of the bobbin arm 11 are in parallel relationship with each other.
  • a shaft 22 supported by bearings 24 and 25 is placed between the legs of the arm 11 and acts to rotate two star plates 26 and 27 by means of a slot and key arrangement 29 providing a solid connection with a flange body 30 which is fixedly mounted to the star plates 26 and 27.
  • bobbin-gripping members 31 and 32 are provided opposite each other at each of the three arms 34, 35 and 36 of the star plates 26 and 27 and at equal radial distances from the axial line of the rotating shaft.
  • the bobbin-gripping member 32 shaped to form a receiving plate, rotates about a shaft extending into the ball bearing 37 fixed at its neck and into a bore 39 in the front face of the opposite bearing 40.
  • the bobbin-gripping member 31 rotates about a shaft 41 extending into the ball bearing 42 which is also fixed at its neck and into the bottom of the spring box 44 via bore 45.
  • a pressing or biasing spring 46 is provided in the cylindrical bore 48 of the spring box 44 and is supported at one end by the rear wall 49 of bore 48 and at the other end by a ball 50 serving as a counterbearing resting at the center of the housing 51 of the spring box 44.
  • the axial shift of the spring box 44 and, therefore, of the bobbin-gripping member 31 is effected by means of a lever 52 guided by a groove 54 in the housing 51 and secured in the spring box 44 by means of a screw.
  • the rotation of the shaft 22 is effected by means of the driving mechanism 55 in the shape of a driving head consisting of a driving hub 56 actuated by means of lever 57, a coupling flange 59 fixed by screws 60 on the bobbin arm 11 and rotatably connected with the hub by means of the thread 61.
  • a seizing member 62 is lead in a bore 64 of the hub 56 and is held under pressure by means of the spring 65 and a counter bearing screw 66.
  • the seizing member 62 engages a tooth 67 of the cam-shaped driving piece 68 which is fixed to the rotating shaft 22 by means of both the key 69 and the groove 70 so that it can be axially moved on the shaft 22.
  • a stop device comprising elements 7] and 72 is pro vided to limit the rotating angle of the hub56
  • the driving mechanism 55 provides dampening and sliding or clutching coupling between the star plates 26 and 27 and the arm 11 In the initial phase of the switching process corresponding to the winding phase during which the package at tains its maximum size.
  • the dining mechanism 55 operates as a dampening coupling through the action of an adjusting ring 74 which is rotatably fixed in the hub 56 by means ol a thread 75.
  • the adjusting ring 74 serves to set the desired tension of the mentioned coupling and is solidly connected with the hub 56 after having been set by means of a safety screw 76 During the switching process the hub 56 is axially moved in the direction of the coupling flange 59 by means of the thread 61 which connects the hub 56 with the flange 59.
  • an creasing coupling effect (as described more exactly heretofore) is established between the arm 11 and the star plates engaging the flange body 30, the shaft 22. the grooved element 82, the discs 79 and 80 and the grooved flange 59 as if the lever 57 were in solid connection with the star plates when switching in the changing direction.
