Definitions

  • the present invention relates to a unit according to the preamble of claim 1.
  • GB 816 096 defining the preamble of claim 1 discloses a twisting unit comprising a sleeve receiving a spindle shaft which is rotatably supported by two bearings located below a drive motor resulting in a relatively long sleeve and spindle shaft.
  • the problem underlying the invention is to allow the torque of the motor to be increased without increasing the load on the bearings.
  • a twisting unit in a double twister is described as an example of a twisting unit comprising a motor provided coaxially with a spindle shaft to drive this shaft, the spindle shaft being rotated to twist a yarn Y.
  • the double twister is composed a plurality of spindles installed in parallel and in particular, is of an individual-spindle-driven type comprising a drive motor individually provided for a spindle shaft in a twisting unit for each spindle.
  • FIG. 1 is a side sectional view of a twisting unit for a single spindle in the double twister.
  • each spindle has arranged between the twisting unit and a winding device located at a downstream position, a feed roller for feeding a twisted yarn in a yarn running direction, a traverse device for traversing a yarn in the axial direction of a winding package, and a yarn guide change guide located at an appropriate position.
  • Each twisting unit has a single spindle shaft 1 and a package loading table 2 on which a supply package P is loaded and which is rotatably provided at an upper end of the spindle shaft 1 via bearings 3, 4.
  • a magnet 5 for holding the supply package P stationary during twisting is provided in an outer circumferential section of the package loading table 2 so that the supply package P is held stationary by the magnetic attraction effected between this magnet and a magnet (not shown) provided on a fixed side opposite the magnet 5.
  • a rotating disc 6 is secured to the upper end of the spindle shaft 1 immediately below the package loading table 2.
  • the disc 6 is composed of a circular bowl section 7 having a diameter larger than a supply diameter and a cylindrical winding section 8 secured under the bowl section 7.
  • a yarn passage 9 is formed in the winding section 8 in a radial direction. The variation in releasing tension is absorbed by automatically varying the amount of yarn wound around the winding section 8 .
  • the spindle shaft 1 extends downward from the disc 6, and a drive motor M for driving the spindle shaft 1 is coaxial ly provided on the extension of the shaft.
  • a drive motor M for driving the spindle shaft 1 is coaxial ly provided on the extension of the shaft.
  • the motor M is directly provided on the spindle shaft 1, and no couplings for transmitting a rotation torque are used.
  • the motor M is loaded on a fixed support 10.
  • the motor M has a cylindrical sleeve 11 provided around the spindle shaft 1 so as to have a predetermined length in the axial direction, a rotor (a permanent magnet) secured to a part of the outer circumferential surface of the sleeve 11, a motor support section 13 provided externally of the rotor 12, a stator 14 provided on the inner circumferential surface of the motor support section 13 opposite to the outside of the rotor 12, a lower bearing support member 15 fitted in the bottom of the motor support section 13, an upper bearing support member 16 fitted in the top of the motor support section 13, a lower ball bearing 17 provided between the sleeve 11 and the lower bearing support member 15 to rotatably support the sleeve 11 below the rotor 12, a lower cap 19 penetrating the support 10 in the vertical direction and having a bottom surface engaging the lower bearing 17, an upper cap 20 fitted on the upper bearing support member 16 and having a top surface engaging an upper bearing 18, and a detection piece (a
  • a motor housing is composed of the upper cap 20, the upper bearing support member 16, the motor support section 13, the lower bearing support member 15, and the lower cap 19 arranged in this order from the top.
  • the motor housing, the sleeve 11, and the upper and lower bearings 18, 17 constitute a holding means for holding the rotor 12 opposed to the stator 14 regardless of the insertion or removal of the spindle shaft 1, that is, after the spindle shaft 1 has been removed from the sleeve 11 of the motor M.
  • the sleeve 11 has a large diameter section 11a provided in the middle thereof in the axial direction and small-diameter sections 11b provided at the respective axial upper and lower end thereof and having a outer diameter smaller than the large diameter section 11a.
  • the rotor 12 is secured to the outer circumferential surface 11a of the sleeve 11, and the upper and lower bearings 18, 17 are provided between the outer circumferential surface of the small diameter sections 11b, 11b and the motor housing (the upper and lower bearing members 16, 15).
  • the large diameter section 11a of the sleeve 11 has an locking section with which the upper end of the rotor 12 is engaged when the rotor 12 is installed.
  • an locking section that engages with the lower end of the upper bearing 18 is formed at the upper end of the sleeve 11
  • an locking section that engages with the upper end of the lower bearing 17 is formed at the lower end of the sleeve 11. Both locking sections define the distance between the upper and lower bearing sections 18, 17 to be larger than the axial length of the rotor 12.
  • a tapered hole 11c the diameter of which gradually decreases from top to bottom is formed in the sleeve 11.
  • a tapered section 1a having an inclination as large as that of the tapered hole 11c of the sleeve is formed on the spindle shaft 1 in such a way that its diameter gradually decreases toward one axial side.
  • the tapered hole 11c and the tapered section 1a are taper-fitted together so as to transmit a rotation torque.
  • the inclination of the tapered surface between the tapered hole 11c and the tapered section 1a is designed so that a rotation torque can be reliably transmitted and so that the spindle shaft 1 can be inserted and removed easily.
  • the axial length of the tapered hole 11c is larger than that of the rotor 12, so that the upper end of the tapered hole lie is located above the secured section of the rotor 12, while the lower end of the tapered hole 11c is located below the secured section of the rotor 12.
  • the rotor 12 is directly subjected to a drive torque caused by the magnetic effect of the stator 14.
  • An axial through-hole is formed inside the sleeve 11 including at least the tapered hole 11c leading from above the rotor 12 to below the rotor 12. This configuration enables a drive torque generated in the rotor 12 to be reliably transmitted to the spindle shaft 1 via the taper-fitting surface.
  • the spindle shaft 1 installed in the sleeve 11 can be rotated in synchronism with the rotor 12.
  • Rotating magnetic fields from the detection piece 21 are obtained by an external control device (not shown) via a magnetic sensor (not shown), and the detected rotation speed is used to maintain the drive motor M at a desired rotation speed during twisting.
  • a yarn passage hole 22 is formed above the spindle shaft 1 so as to lead to the upper end of the shaft 1.
  • the yarn passage hole 22 is in communication with the yarn passage 9 formed in the rotating disc 6.
  • a tensor 23 for applying a predetermined tension to the yarn Y is provided inside a center shaft of the supply package P in such a way as to be located above the spindle shaft 1. The yarn Y released from the supply package P advances into the center shaft of the supply package P from above, where the tensor 23 applies the predetermined tension to the yarn Y.
  • the yarn Y passes through the yarn passage hole 22 and the yarn passage 9 and then jumps outward (in the radial direction of the rotating disc 6) to reach a balloon guide (not shown) located above the supply package P on an extension of the center shaft.
  • the yarn Y leaving the yarn passage 9 swivels around the supply package P due to the rotation of the rotating disc 6 while forming a balloon guide between the spindle and the balloon guide.
  • the package loading table 2 has a package cover 24 provided so as to cover part or all of the outside of the supply package P to prevent the ballooned yarn T from coming in contact with the outer circumferential surface of the supply package P.
  • a portion of the spindle shaft 1 other than that in which the yarn passage hole 22 is formed has an air supply hole 25 formed there through in such a way as to lead to the lower end thereof.
  • the spindle shaft 1 is hollow, and like the yarn passage hole 22, the air supply hole 25 is in communication with the yarn passage 9.
  • a joint member 26 is provided below the spindle shaft 1.
  • An air supply pipe (not shown) is connected to the joint member 26 so as to supply injected air to the air supply hole 25 from below.
  • the rotating section of the motor M is installed so that the lower bearing 17 is located between the lower bearing support member 15 and the small diameter section 11b of the sleeve 11 at its lower end, while the upper bearing 18 is located between the upper bearing support member 16 and the small diameter section 11b of the sleeve 11 at its upper end.
  • the upper and lower caps 19, 20 are installed to constitute the motor M in which the stator 14 is located outside the rotor 12 opposite thereto to provide a predetermined rotation torque to the rotor 12.
  • the rotor 12 Since the rotation torque of the motor M relates to the opposed area between the rotor 12 and the stator 14, the rotor 12 is secured to the large diameter section 11a to enable the reduction of the axial length of the rotor 12 required to obtain a required rotation torque. Accordingly, it enables the reduction of the axial length of the spindle shaft. In addition, the outer diameters of the portions of the spindle shaft supported by the upper and lower bearings 18, 17 are reduced despite the increased outer diameter of the portion to which the rotor 12 is secured. Consequently, the fast-rotation durability of the bearings 18, 17 is improved.
  • an body is configured that is inserted into the motor M (the sleeve 11).
  • This inserted body is also subjected to a predetermined balancing operation.
  • this body including the spindle shaft 1 is inserted from above into the motor M with the sleeve 11 rotatably installed therein as described above ( Figure 3), thereby enabling the spindle shaft 1 to be installed so as to rotate integrally with the sleeve 11.
  • the spindle shaft 1 is inserted in such a way that its lower end passes beyond the lower end of the sleeve 11.
  • the inserted spindle shaft 1 is guided through the tapered hole 11c so as to be accurately positioned on a predetermined center axis (the rotating axis of the motor M) and at a predetermined height. This enables the spindle shaft 1 to be rotated stably at a high speed.
  • the motor 110 for rotationally driving the spindle shaft 104 is disposed below the rotating disc 115.
  • the motor 110 is composed of a rotor magnet 132 fixedly installed in the outer circumference of the spindle shaft 104, a stator coil 131 placed in an outer circumferential section of the rotor magnet 132 opposite to the magnet 132, and a motor housing 134 for the motor 110.
  • the motor housing 134 is composed of a motor support section 126 having the stator coil 131 secured to its inner circumferential surface, an upper support member 127 that is a bearing support section mounted at the upper end of the motor support section 126 to rotatably support the spindle shaft 104 via a bearing 127a, and a lower support member 128 that is a bearing support section mounted at the lower end of the motor support section 128 to rotatably support the spindle shaft 104 via a bearing 128a.
  • the spindle shaft 104 is pressed in the bearings 127a, 128a.
  • the lower support member 128 of the motor housing 134 located at its lower end is secured to the frame 109 in order to support the twisting unit 1 on the frame 9.
  • a cap 129 composed of an approximately cylindrical member is attached to the lower end of the lower support member 128, and a screw hole 129a penetrating the cap 129 in the vertical direction is formed approximately at its center in a top view.
  • the screw hole 129a is placed coaxially with the spindle shaft 104, and an air joint 130 is screwed and fitted in the screw hole 129a from below.
  • the air joint 130 is in communication with the guide hole 104a in the spindle shaft 104 to guide air from the exterior of the motor housing 134 to the guide hole 104a.
  • the rotor magnet 132 of the drive motor 110 is composed of a rare earth magnet such as a neodium magnet that is a permanent magnet having a very high magnetic force, thereby enabling the drive motor 110 to be compactified and to have a high drive capability.
  • stator coil 131 is configured as a cored coil having an iron core 131a.
  • a detection magnet 133 is secured to the spindle shaft 104 under the rotor magnet 132 in order to detect the rotation speed of the spindle shaft 104, and is composed of a plastic magnet that is a permanent magnet having a low magnetic force (weaker than that of the rotor magnet 132).
  • a magnetic sensor 133a is mounted on the motor support section 126 opposite to the detection magnet 133 to detect magnetic fields from the magnet sensor 133 in order to detect the rotation speed of the spindle shaft 104.
  • a plurality of fins 126a protruding outward are formed on the outer circumferential surface of the motor support section 126 constituting the motor housing 134.
  • the fins 126a are formed to extend in the vertical direction so as to efficiently cool hot air resulting from driving effected by the drive motor 110 when ah air flow generated due to the rotation of the rotating disc 115 passes through the motor housing 134 of the drive motor 110.
  • a fitting section 127b in which the motor support section 126 is fitted is formed on the inner circumferential surface of the lower end of the upper support member 127, and the motor support section 126 has formed at its upper end a fitting section 126b configured to have a smaller diameter than the remaining portion.
  • the upper support member 127 and the motor support section 126 are connected together by fitting the fitting section 126b in the fitting section 127b so that they are in contact with each other.
  • fitting sections of the motor support section 126 and the lower support member 128 are fitted together in such a way that the inner circumferential surface of the motor support section 126 is in contact with the outer circumferential surface of the lower support member 128.

  • the motor 110 is capable of fast rotational driving.
  • a bolt 143 is inserted and screwed in the screw hole 129a in the cap 129 from below.
  • the bolt 143 inserted and screwed in the screw hole 129a abuts on the lower end of the spindle shaft 104.
