Definitions

  • PATENTEDAus 15 m2 gtaqtzta Inventor SHUZO KAWAMURA SPOOL HOLDER This invention relates to a spool holder which, upon insertion of a spool onto the spool holder to hold the spool at its centerline region, is caused to be increased in its diameter to establish close contact between the inner diameter of the spool and the outer diameter of the spool holder, thereby supporting the spool.
  • a holder part A comprises a main body 1, a ring body 2 and a head body 3.
  • the main body 1 has a tube body 4 fixed to the centerline region thereof and is provided with a cut 5 formed in the upper surface and a taper portion 6 on the lower surface.
  • a lever 9 having an end claw 8 is pivotally mounted on a pin 7.
  • the numeral 10 denotes a spring constantly urging the lever 9 in a counterclockwise direction.
  • the tube body 4 is provided with elongated openings 11 and 12. The elongated opening 11 is adapted to permit the ingress and egress of the claw 8 of lever 9 therethrough,
  • the head body 3 has a taper portion 15 on the top and is fixed to the lower end of the holder shaft 13.
  • the ring body 2 is fitted in an annular recess between the head body 3 and the main body 1.
  • the ring body 2 is made of a soft deformable material such as rubber or synthetic resin. 'As shown in the drawing, an annular recess 2a may be formed in the inner peripheral surface of ring 2.
  • a spring 17 is inserted onto the upper end 16 of the holder shaft 13 and a spring retainer collar 18 is fitted to the upper end portion of the holder shaft, whereby the holder shaft 13 and the tube body 4 are constantly urged to move away from each other.
  • the numerals 19 and 20 denote endless chains for supporting the tube body 4, which endless chains will be attached to the tube body when it is necessary to move the spool holder.
  • the numeral 21 denotes a roll which rolls on a bracket 22.
  • the numeral 23 denotes a spool.
  • Claw 8 of lever 9, spring 10 and pin 14 operate as a means for latching main body 1 and head body 3 in spaced relation to retain ring body 2 in an unexpanded state, but which is releasable upon engagement with spool 23. 7
  • the spool 23 is to be inserted onto the holder part A.
  • the axis of the spool 23 and the axis of the holder shaft 13 are brought into alignment with each other and the spool 23 is then inserted onto the holder part A from below.
  • the spool 23 pushes the end of the lever 9 in a clockwise direction against the resilient force of the spring 10, the engagement between the fixing pin 14 and the claw 8 of the lever is destroyed resulting in the upward movement of the holder shaft 13 and hence the upward movement of the head body 3 fixed to the holder shaft 13.
  • the ring body of soft material is compressed between the taper portion 6 of the main body 1 and the taper portion 15 of the head body 3.
  • the ring body bulges outwardly to have its outer diameter increased into close contact with the bobbin innerdiameter, thereby gripping the bobbin.
  • this is achieved by pushing down the front end 16 of the holder shaft 13 against the force of the spring 17 to cause the fixing pin to be moved downwardly below 'the claw 8 of the lever 9 which is constantly urged counterclockwise, and then removing the downward force on the front .end 16 of the holder shaft 13, whereupon the holder shaft 13 and hence the fixing pin 14 tend to move upwardly under the action of the spring 17.
  • this upward movement is prevented overcome since the fixing pin 14 again engages the claw 8 of the lever 9.
  • the ring body 2 is not compressed and, the its outer diameter does not contact the inner diameter of the spool 23, with the result that the spool 23 is released from the holder part A.
  • the chains 19 and 20 may be suitably moved to move the tube body 4 by supporting the latter by the roll 21 rolling on the bracket 22.
  • the supporting and releasing of a bobbin can be carried out by the engagement and disengagement of the holder shaft 13 and the lever installed in the cut in the main body, the bobbin can be supported by simply inserting it onto the holder part A and, when it is desired to release it, this can be achieved by simply giving a downward push to the holder 13.
  • the supporting and releasing of a bobbin can be achieved in one touch operation.
  • the ring body will deform along such tapers, and since the force of deformation is determined by the spring 17, a suitable pressure for supporting a spool can be easily obtained. Thus, even with a single ring body, a sufficient holding force can be obtained. Therefore, even a bobbin whose diameter is two to three times as large as its height can be simply supported. Moreover, there will be no danger of causing damage to the inner surface of the bobbin.
  • a spool holding device comprising a main body and head body disposed in axial alignment and defining therebetween an annular recess, a ring of soft deformable material disposed in said recess, means tending to bias said main and head bodies axially toward each other so as to axially compress and radially expand said ring, and means for latching said main and head bodies in spaced relation so as to retain said ring in a released state, said latching means being releasable upon engagement with a spool when the spool is received over said main and head bodies.
  • said ring is formed of rubber.
