  • the present invention relates to a stop mechanism for a rotary textile spindle which includes electromagnetically operated brake means which are nonrotatable and bring the spindle to a stop when engaging a brake surface on the same.
  • textile spindle is used in the present application for spindles and other rotary elements used in spinning, twisting, and draw twisting machines, and similar apparatus.
  • Textile spindles of this type carry a tube or bobbin on which a yarn or thread is wound up to form a package.
  • Electromagnetic brake means for spindles are known, and one construction according to the prior art is disclosed in the U.S. Pat. No. 3,415,050 which has a freely rotatable driven pulley which can be coupled with the spindle.
  • An axially movable coupling plate is biassed by a spring to engage the pulley and is controlled by an electromagn et to simultaneously disengage the spindle and to engage a brake surface of the electromagnet so that the spindle is braked and then stopped since the electromagnet is not rotatable.
  • Another object of the invention is to provide a stop mechanism for a textile spindle which, regardless of unavoidable oscillatory movements of the rotating spindle, brakes the same uniformly without any influence of the oscillation on the braking operation.
  • Another object of the invention is to combine the electromagnetic brake means with coupling means by which a freely rotatable pulley is coupled with the spindle when the brake means is disengaged, and disengaged from the spindle when the brake means is operative to brake and stop the spindle.
  • the stop mechanism of the present invention comprises a brake means including an electromagnet which is movable toward and away from a magnetizable armature portion of the spindle so that upon energization of the electromagnet, the brake means moves toward the armature portion until abutting a brake surface of the spindle, while the brake means returns to its inoperative position, preferably by the action of the force of gravity, when the electromagnet is deenergized.
  • the brake means and its electromagnetic means move toward the brake surface on the spindle when the electromagnetic means is energized, and abuts the brake surface with a great force. Any rattling noise or irregular braking of the rotary spindle is avoided.
  • the spindle bearing is less stressed during the braking operation than in known brake stop mechanism according to the prior art.
  • the brake of the stop mechanism may be a radial or an axial brake, and is preferably constructed as an axial brake in which the brake means moves in axial direction of the spindle between an inoperative position and a braking position, which has the advantage that a single brake means can produce very great brake forces without producing transverse forces stressing the spindle shaft, and without substantially increasing the bearing forces of the spindle shaft acting on the bearing of the spindle.
  • the bearing force is either completely eliminated, or increased only by the weight of the brake means, depending on the position of the brake means above or below its armature on the spindle.
  • a magnetizable armature portion of the spindle is located vertically directly above the brake means so that the same is raised to a braking position abutting the brake face of the spindle when the electromagnetic means in the brake means is energized.
  • the brake means moves due to the action of the force of gravity downward back to its normal inoperative position.
  • the invention is particularly advantageously applied to textile spindles which include a rotary spindle, a pulley freely rotatable mounted on the spindle, and coupling means which have a coupling position connecting the pulley with the spindle for rotating the latter, and a disengaged position in which the driven pulley is separated from the rotary spindle so that the same can be braked to a stop.
  • the coupling means -is in the disengaged position when the brake means is in the braking position, and is in the coupling position when the brake means is in the inoperative position due to deenergization of its electromagnetic means.
  • a stop mechanism comprises a support, a textile spindle means mounted on the support for rotation and having a magnetizable portion, and brake means mounted on the support for movement toward and away from the spindle means between an inoperative position, and a braking position abutting the spindle means.
  • the brake means is nonrotatably connected with the support and includes electromagnetic means positioned so that magnetic flux produced by the electromagnetic means flows through the magnetizable portion. As a result, the brake means is magnetically attracted to and pressed against the spindle means in the braking position for braking and stopping the same when the electromagnetic means is energized.
  • the brake means returns to the inoperative position, preferably due to the action of the force of gravity since in the preferred embodiment of the invention, the braking position is higher than the inoperative position.
  • the spindle means is of the type having an integral pulley
  • a lower flange of the pulley is advantageously used as the magnetizable armature portion for the electromagnetic means of the brake means.
  • the brake means is operatively connected with the coupling means for causing movement of the same to the disengaged and engaged positions, respectively, when the brake means moves between the braking and inoperative positions, respectively.
  • spring biassed means act on the coupling means for urging the same to the engaged position, and the brake means moves the coupling means to the disengaged position when the electromagnetic means is energized and the brake means moves to the braking position.
  • the brake means Upon deenergization of the electromagnetic means, the brake means returns to the inoperative position, and the spring biassed means moves the coupling means to the engaged position.

  • annular brake lining 26 consisting of a nonmagnetic material is mounted in a corresponding annular groove in the top face of the magnetic annular member 17, covering winding 23 and leaving two annular top face portions 27 and 29 of annular member 17 uncovered.
  • Brake lining 26 has a brake face on top which is located above the top face portions 27 and 29, and cooperates with a brake face 17 at the bottom of the magnetizable flange 12.
  • Threaded guide pins 10 are screwed into the yoke portion 21 of the annular member 17 and have inwardly projecting portions located in the diametrically opposite guideways 7 for guiding the annular brake means ll, 17, 23, 26 for axial movement on support 4, while connecting the annular brake means with support 4 in such a manner that the annular brake means cannot turn relative to support 4 which is fixed to the spindle rail.
  • the magnetizable flange 12 is located directly above the annular top face portions 27 and 29, spaced a small airgap from the same when the annular brake means 11 is in its normal inoperative position resting on flange 5 of support 4 due to its weight.
  • the top face of brake lining 26 is also spaced from the brake surface 16 at the bottom of flange 12 by an airgap.
  • Flange l2 and brake means 11 form the stop mechanism 3 by which the spindle 2 can be braked to a stop.
  • the annular brake means 11, and more specifically the annular magnetizable member 17, has sufficient radial play on support 4 so that the brake lining 26 can fully abut the braking surface 16 of flange 12 when brake means 11 is raised to a braking position.
  • brake means 11 When switch 25 is open, and no current energizes the winding 23, brake means 11 is in the illustrated inoperative posi tion, resting on flange 5 so that a rope or belt passing about pulley 13 rotates the spindle means 2 including shaft 15 in bearing housing I, the upper spindle portion 14 on which the tube or cop is mounted, and the magnetizable flange 12 which forms an armature for the electromagnetic means 23, 27.
  • the textile spindle means 51 has a spindle shaft 52 mounted in a bearing housing 1 for rotation about a vertical axis.
  • Bearing housing 1 is secured to spindle rail 6 and has a bottom flange 70.
  • a tubular support 53 and a protective ring 54 are secured to spindle shaft 52, and tubular support 53 has a tubular wall surrounding the upper portion of bearing housing 1.
  • a cover ring 55 is secured by screws 55a to support 53.
  • Antifriction bearing means mount a pulley 57 on support 53 for free rotation about the axis of the spindle means 51.
  • the spindle means 51 further includes coupling means 61 which has an engaged position coupling pulley 57 with the rotary spindle 52 to 55, and a disengaged position in which the spindle 52 to 55 is not rotated when pulley 57 is driven by a rope or belt, not shown.
  • Coupling means 61 includes an annular member 74 having a magnetizable flange 74a to which an annular lining 62 is secured.
  • Support 53 has a flange 58 into which bolts 59 are screwed which project into recesses of member 74 and are surrounded by springs 60 abutting the heads of bolts 59, and also coupling member 74 so that the same is urged together with flange 74a and coupling lining 62 to an engaged position in which lining 62 abuts flange 57a and couples pulley 57 with the rotary spindle 52 to 55.
  • the annular brake means 11' surrounds the bearing housing 1', and is composed of an annular magnetizable member 75 which is constructed as described with reference to the annular magnetizable member 17 of the embodiment of FIG. 1.
  • the ring 63 consists of a magnetizable material, such as iron, and has U-shaped cross section. In the upwardly open groove 64, the winding 65 and a brake lining 66 are arranged. Ring 75 has a circular inner surface to which a ring-shaped sinter bearing 67 is fixedly secured.
  • the inner surface of the bearing ring 67 has small radial play on the cylindrical outer wall of bearing housing I, so that the brake means 11 is movable in axial direction, but cannot turn relative to bearing housing 1 due to the fact that four guide pins 71 project outwardly from flange into radial grooves 68 of brake means 11'.
  • Bearing housing I and flange 70 fonn a support on which the annular brake means II is mounted for axial movement only.
  • the annular bottom face 72 of the circular wall 73 of support 53 is spaced a small distance from the annular top face of the sinter bearing ring 67, at best seen in FIG. 4, and forms a bearing surface against which the sinter bearing ring 67 abuts when brake means 11 is moved upward to a position in which the brake lining 66 is still spaced from the brake surface 73 of the magnetizable coupling flange 74a.
  • the braking surface 73 of coupling member 74 is slightly higher than the annular stop face 72, but the vertical distance between the two surfaces is very small, and may be 0.2 mm. If this distance is too great or too small, coupling means 61 may not be disengaged upon energization of the electromagnetic means 75, 65.
  • coupling member 74 may not be attracted with sufi'tcient force to overcome the resistance of spring 60, and if the distance is too small, the downward movement of coupling member 74 may be insufficient to separate the coupling lining from flange 57a of the pulley so that the pulley would remain coupled with the spindle while the same is being braked.
  • the sinter bearing ring 67 is designed and constructed to be worn to the same degree as the brake lining 66 and the top pole faces of the magnetizable ring 63 so that the respective gaps always maintain the same width, to which they were once accurately adjusted.
  • the distance between the brake surface 73' and the brake lining 66 is not critical, since the brake means 11' is pulled upward to the position abutting stop surface 72 even if the annular pole faces on top of the magnetizable ring 63 are spaced slightly too far from bottom surface 73 of the magnetizable coupling flange 74a.
  • the combined stop and coupling mechanism according to the embodiment of FIGS. 3 and 4 has substantial advantages over prior art constructions. It is not necessary to very accurately adjust the airgap between the magnetizable ring 63 and the magnetizable coupling flange 73, which serves as an armature. This distance is not critical, and therefore the gap need not be readjusted after use.
  • the width of this airgap can be substantially greater than in known electromagnetic brake arrangements, so that there is no danger of an accidental contact of coupling flange 74a with the top face of brake means 11 when the spindle is subjected to unavoidable oscillations during rotation. Furthermore, the bearing of spindle shaft 52 in bearing housing 1' is'hardly more stressed during braking of the spindle and disengagement of coupling means 61 than during normal rotation of the driven spindle.
  • brake lining 66 and brake surface 73 of coupling member 74 align each other to obtain full surface contact, so that no oscillations of the spindle are caused by the brake forces.
  • FIGS. 5 and 6 has the same advantages.

  • the annular brake means 11 which includes an annular magnetizable member 75, a winding 65, and a brake lining 66, is mounted on the bearing housing, not shown, in which shaft 52 of the spindle is supported for rotation about the vertical axis. Rotation of brake means 11" is prevented by a pin and guideway construction as described with reference to FIG. 3, so that brake means 11" is movable in axial direction between a lower inoperative position and a higher position.
  • the cylindrical support 53 which is secured to spindle shaft 52, has a magnetizable flange 76 consisting of iron and constituting an armature for the electromagnetic means 75, 65.

  • the annular coupling means 77 has at least three recesses into which corresponding three springs 78 project. Springs 78 urge the annular coupling means 77 to engage the conical abutment face 79 in the interior of pulley 57.
  • Coupling means 77 is mounted on a cylindrical outer surface of support 53' for axial movement, but cannot turn relative to support 53' since three bolts 81, circumferentially spaced 120 from each other, are located in bores of coupling flange 76 of support 53, and in aligned bores in the annular coupling means 77.
  • the bottom faces of bolts 81 are plane and disposed spaced a small distance from the brake lining 66.
  • brake means 11 When winding 65 of electromagnetic means 75 is again deenergized, brake means 11" drops down to its normal inoperative position in which the brake lining 66 is spaced from the brake surface 73 of flange 76. In this position, bolts 81 of coupling means 77 are released by the brake means 11, and springs 78 push coupling means downward to the normal position abutting coupling surface 79 of pulley 57 so that the same is coupled with the spindle and rotates the same.
  • the width of the gap between the top pole faces of the electromagnetic means 75 and the magnetizable flange 76 is not critical, so that variations of the gap due to the wear of the parts are immaterial and require no readjustment.
  • FIG. 7 illustrates another embodiment of the invention in which a brake means 11" having an electromagnetic means 75 is mounted for axial movement on four axially projecting guide pins secured to the flange 70 of thebearing housing 1' so that brake means 11 can move in axial direction between a lower inoperative position and a higher braking position, but cannot turn relative to the support 6, 70, 1.
  • a flange member 76' is secured by screws 76a to the lower end of support 53" which is secured to spindle 52.
  • Flange member 76 has an inner ring portion 92 and an outer ring portion 91 consisting of a magnetizable material, and connected by an intermediate ring portion 93 consisting of a nonmagnetizable material, for example a synthetic plastic material.
  • a coupling means 94 is mounted on support 53 for axial movement and includes an annular coupling member 95 and a coupling lining 62 secured to each other. Coupling means 94 is fixedly secured to three bolts 76 which are spaced from each other 120 in circumferential direction.
  • Bolts 96 are guided in bores 97 of the intermediate nonmagnetizable ring 93 for movement in axial direction.
