Definitions

  • the present invention relates to a structure for mounting a spindle-bearing housing on a spindle rail of textile machines, wherein the spindle blade with a driving whorl is rotatably carried in the housing.
  • the mounting is especially applicable for use on draw twisting equipment employed to process manmade continuous filaments and the like.
  • Textile spinning spindles are secured to the framework of textile processing machines by various types of mountings.
  • Such mountings are either elastic or rigid.
  • Present rigid mountings cause sound levels above that recommended for human hearing conservation.
  • At higher rotative speeds it has been found that a non-rigid or elastic mounting provides certain advantages such as reducing vibrations caused by an out of balance load during critical speed phases but does not reduce noise to a satisfactory level.
  • these known elastic mountings are not entirely satisfactory when a relatively large package of yarn is taken up at high speeds of 10,000 to 20,000 rpm.
  • an elastic mounting of a spindle-bearing housing to a spindle rail permits the spindle to be turned at high speeds while a large package of yarn is built. The noise produced while using the new device is significantly reduced. Also, maintenance of the device is not an expensive consideration.
  • existing equipment having rigid mounts can easily be converted to non-rigid mounts in an inexpensive manner by incorporating the inventive features of the present device.
  • a textile machine especially a draw twister, is provided with special mountings for spindle-bearing housings with the result that audible frequency vibrations are reduced.
  • the machine has a spindle rail or frame with at least one opening passing therethrough. Through the opening a spindle-bearing housing extends vertically.
  • the housing has an upper bearing and a foot bearing for joumaling a spindle blade therein.
  • a driven whorl is part of the blade; and together they support a tube on which twisted yarn is wound.
  • a first support plate is fixedly carried on the upper portion of the housing.
  • the support plate has at least three selectively spaced openings therethrough.
  • a second supporting plate complimentary with respect to the first plate.
  • the second plate is spaced just below the first by means of elastic members compressed therebetween. These members preferably are elastic washers located in each of the openings in the first plate.
  • the two plates are secured together preferably by bolt members extending through the washer members.
  • a tubular extension is provided on the second plate extending vertically downward through the rail opening and is spaced from the rail. Means co-act with the tubular extension to secure the second plate to the rail.
  • FIG. 1 is a partially sectioned elevation of a conventional rigid mounting of a spindle-bearing housing to a machine rail or frame, with the structure of the bearing being shown in detail;
  • FIG. 2 is a partially sectioned elevation of the non-rigid mounting of a spindle-bearing housing to a machine rail in accordance with the present invention.
  • FIG. 3 is an exploded perspective view of the mounting assembly of the present invention, the rail and spindle blade not being shown in order to illustrate the assembly in a better fashion.
  • numeral 1 denotes a spindle rail or bolster rail as a part of a machine frame of a textile machine for twisting and collecting yarn-in the form of a package.
  • a spindle-bearing housing or bolster 2 is mounted on the rail and extends through an opening 3 in the rail. It is understood that the rail is provided with a plurality of identical holes along the length of the machine and quite commonly on the backside of the machine to provide a like number of spindle positions. Only one position is illustrated for convenience.
  • the spindle-bearing housing comprises a tubular casing 5 having an external thread 6 on the upper portion thereof that extends through the opening.
  • the housing is secured to the rail by means of nuts 7 and flange 8 and washer 10. This is, of course, a rigid mount.
  • a spindle blade 11 is journaled in the spindle-bearing housing by means of an upper roller bearing 12 providing transverse support and a foot bearing 13 providing vertical support.
  • a spirally slotted tubular spring 15 and oil filled coil 16 form part of the bolster.
  • a whorl or wharve 17 receives internally the upper end of the bolster in order to bring the bobbin base 18 and upper bearing 12 as close together as practicable.
  • This base supports a. bobbin (not shown) or other tube-like member on which yarn is wound and carries a drive lug 19 which engages in a corresponding member in the bottom of the pim.
  • a belt (not shown) rotatably drives the whorl at selected speeds.
  • FIG. 2 a similar spindle-bearing housing 2 is shown mounted with clearance in a hole in spindle rail 1.
  • a spindle blade 11 having a belt driven wharve 17 is journaled in a similar manner in the housing.
  • An upper support plate'20 having a generally triangular shape is fixedly mounted to the upper portion of bolster 2.
  • the plate has a central threaded opening that receives the threaded portion of the bolster.
  • a hole 21 See FIG. 3) is provided. It is understood that the plate can have any other desired shape and can have three, four or more holes.
  • a second plate 22 correspondingly shaped with respect to plate 20 has a central opening 23 for receiving the upper end of the bearing housing with clearance.
  • a tubular extension 25 on the second plate having an exterior thread extends through the rail opening 3 with clearance.
  • Elastic ring members or grommets 26 are placed in each of the holes 21.
  • these ring members are double flanged to fit snugly in the holes.
  • the rings are centrally severed as shown in FIG. 3.
  • the rings are made of suitable elastomers.
  • the elastomer preferably is electrically .conductive in order that static charges of electricity generated by the drawing of the spindles and the winding of the yarn are dissipated through the machine to a ground.
  • a bolt member 27 is placed to secure the upper support plate 20 to the second plate 22 and engages a nut 28.
  • a sleeve 29 extends through the grommet and surrounds member 27.
  • a braking device 30 for decelerating the spindle blade is also illustrated in FIGS. 2 and 3.
  • the second plate 22 has a downwardly bent section 31 on which the device is secured by means of spacers 32, bolts 33 and nuts 34.
  • the braking device comprises an elongated lever plate 36. When the bottom part of the plate is pushed toward the spindle-bearing housing, rubber mount 35 flexes; and the braking surface 37 engages the outer surface of whorl 17. Dofi'er guard 38 prevents removal of the blade while doffing of the bobbins are accomplished. To remove the blade, lever plate 36 is pulled away providing clearance for the whorl to pass the dofler guard.
  • the configuration of the present device permits ease of selection of proper elastomer material and configuration to reduce transmissibility to a minimum and still obtain stable performance of the rotating unbalanced spindle.
  • the bottom half grommet is the vibration isolator, and the top half grommet controls rebound and acts as dampers. Elastomer hardness, areas and preloading are selected to obtain the required natural frequency.
  • this device eliminates resonance between neighboring spindles thereby considerably reducing the over all sound level.
  • a spindle rail formed with at least one opening passing therethrough;
  • a spindle-bearing housing extending through said openmg;
  • a first support plate fixedly carried on the said housing;
  • a second complementary supporting plate having an opening through which the said housing passes, in spaced relation;
  • fixing means coacting with the tubular extension to secure the second plate to said rail;
  • a spindle mounting comprising in combination:
  • a spindle rail formed with at least one opening passing therethrough;
  • a first support plate fixedly carried on the said housing and having at least three openings passing therethrough;
  • a second complementary supporting plate having an opening through which the said housing passes in spaced relation;
  • fixing means coacting with the tubular extension to secure the second plate to the rail;
  • a spindle mounting comprising in combination:
  • a spindle rail formed with at least one opening passing therethrough;
  • a spindle-bearing housing having an upper bearing and foot bearing therein, having an exterior thread on the upper portion thereof and extending vertically through said opening;
  • a first support plate fixedly carried on the upper threaded portion of said housing and having at least three openings passing therethrough;
  • a second complementary supporting plate having an opening through which the said housing passes in spaced relation;
  • a double flanged electrically conductive ring member located in each of said openings in the first supporting plate to non-rigidly space the second plate below the first plate;
