Definitions

  • the spindles of the twisting machine are mounted on spindle rails which are directly or indirectly mounted on the machine frame by omnidirectally acting damping members such as rubber pads.
  • a cover can be disposed about the spindle rails and spindle drives to damp noise.
  • a damping element can be secured about the spindle rail to damp noise.
  • This invention relates to twisting machines and more particularly to twisting machines on which a thread is wound or unwound from a bobbin.
  • the invention provides a twisting machine having a machine frame with longitudinally extending stationary spindle rails to each side of the frame, each of which supports a plurality of spindles.
  • the spindle rails are con-.
  • dampening members such as resilient blocks, are preferably mounted between the spindle rail frame and the machine frame at the greatest distance possible from the central axis of the machine frame.
  • the spindle rails are surrounded by a noise abating cover in order to further reduce the noise generated by the machine.
  • the noise-abating cover is connected by means of a rigid connecting piece to the machine frame and encloses at least a part of the drive elements for the spindles which may also vibrate with the spindles.
  • the noise-abating cover is connected by means of a dampening member to the machine frame.
  • the noise-abating cover is connected directly to the spindle rails by means of a dampening member.
  • FIG. 1 illustrates a crosssectional view of a twisting machine according to the invention
  • FIG. 2 illustrates a view taken on line llIl of FIG. 1;
  • FIG. 3 illustrates a view taken on line III--Ill of FIG. 1 of a crossmember
  • FIG. 4 illustrates a side view of a modified twisting machine according to the invention
  • FIG. 5 illustrates a view taken on line V-V of FIG. 4.
  • FIG. 6 illustrates a cross-sectional view of a modified noiseabating cover about a spindle rail according to the invention.
  • the twisting machine has a rigid frame 6 which is secured as by bolts to a floor and which is constructed of a plurality of spaced upstanding supports 4 connected together by longitudinally extending elements 5.
  • a spindle rail 2, 3 is disposed on each side of the machine frame 6 and supports a plurality of longitudinally disposed spindles l thereon, as is known, for example, by a rigid or flexible mounting.
  • the spindles 1 in turn carry rotatable bobbins 7 thereon for winding and unwinding of thread thereon as is known.
  • rigid crossmembers 8 uniform intervals by rigid crossmembers 8 to form a rigid ladderlike frame in order to suppress the forces generated by the i315 the spindles and the spindle rails to achieve a reduction of the.
  • a spindle drive of known construction is mounted on the frame 6 and includes a tape 9 which passes around the spindles l to impart a rotating force thereto.
  • the momentum which acts on the spindle rails 2, 3 due to the forces generated by the tape 9 are also taken up by the ladderlike frame of spindle rails 2, 3 and crossmembers 8.
  • each dampening member 11 includes an upper metal plate 12 and a lower metal plate 13 which are vulcanized to the rubber pads 10 sandwiched therebetween and which serve to secure the members 11 to the spindle rails and machine frame supports 4.
  • the upper metal plate 12 is secured as by screws to a spindle rail 2 while the lower metal plate 13 is secured as by screws to a support 4.
  • the upper metal plate 12 can be used as a connecting piece to connect two adjacent sections 14, 15 of a spindle rail together at a junction point 16 with suitable screws.
  • the dampening member 11 is positioned so that the junction point 16 is disposed in the middle plane of the dampening member 11 (as indicated in dash-dot lines).
  • the spindles 2, 3 are positioned so that the distance between the spindle rails 2, 3 corresponds to about the width of the machine frame 6 with the result that a desirably large distance is achieved between opposite supporting points of the ladderlike frame on the resilient blocks 11 about the vertical plane defined by the central longitudinal axis of the machine frame. Consequently, notwithstanding the elasticity of the silent blocks 11, the horizontal position of the ladderlike frame is sufficiently maintained even under the influence of the momentums originating from the spindles 4.
  • the dampening members 11 are sized to be, for example, 5 cm. by 8 cm. with a 4 cm. thickness or height, and have a Shore hardness of, for example, 45 degrees.
  • the spindle rails 2, 3 are of rectangular cross section so as to present an ideal spindle rail design in which a mass as large as possible presents an emitting surface as small as possible, and in which a sufficiently high momentum of resistance is reached so that the amplitudes of the vibrations caused by the spindle forces can be kept as small as possible.
  • the cross section of the crossmembers 8 can also be chosen in a similar manner. For example, as shown in FIG. 3, a crossmember can be formed with a circular cross section in the zone between the spindle rails.
  • the crossmembers 18 of the ladderlike frame are mounted as by screws via the silent blocks 19, 20 directly onto longitudinal members 21, 22 which form part of a machine frame 23.
  • the dimensions to be chosen of the silent blocks 19, 20 arranged between spindle rails 24 and machine frame 23 largely depend on the conditions between the diaphragms 25 of the draw-twisting machine shown as an example.
  • the weight of the elements supported amounts to 80 kg. per dampening member 19.
  • a dampening member 19 of dimensions of 5 cm. by 8 cm. by 4 cm. and a Shore hardness of 45 degrees measurements which have been carried out have shown that the vibration forces acting on the machine frame at a spindle speed of approximately 10,000 rpm. are reduced to about 2 percent of the forces which would act if the spindle rails were otherwise rigidly connected to the machine frame.
  • a noise-abating cover 30 is connected by means of a support member 32 which can be designed as a rigid member or as a dampening member (FIG. 5) with the machine frame 23, which practically no longer vibrates, and is arranged around a spindle rail 24 and along at least the length of the belt 29.
  • the inside of the cover 30 can be provided with a noise-abating or antivibration lining 31 in order to damp out the noise therein.
  • noise emission by a spindle rail can be further reduced by attaching a cover 33 formed of two parts which are screwed together directly to the spindle rail 35 via a dampening element 34.
  • the dampening element 34 which can be a dampening substance, such as polyurethane foam, is cast into the cover 33 to fill the space between the spindle rails 35 and cover 33 in order to avoid the formation of an echo chamber within the cover 33. Experiments have shown a reduction of about 6 decibels of the noise emission level with the use of this cover 33 and dampening element 34.
  • the invention relates to any twisting machine for textile threads and includes all machines on which a thread is taken up by, or taken off from, a bobbin placed on a spindle and twist is imparted.
  • the twisting machines included are ring-twisting, draw-twisting, ring-spinning, as well as uptwisting machines and twisters arranged in tiers, all containing spindles arranged on a spindle rail mounted along the machine.
  • a rigid frame including longitudinally extending stationary spindle rails to each side of said machine frame for supporting a plurality of spindles and a plurality of crossmembers rigidly connected to and across said spindle rails, and a plurality of omnidirectionally acting dampening members supporting said rigid frame on said machine frame.
  • dam pening members are each mounted on said machine frame at the greatest distance possible from the central longitudinal axis of said machine frame.
  • dampening members are disposed between said crossmembers and said machine frame.
  • dampening members are disposed between said spindle rails and said machine frame.
  • each said crossmember has a circular cross section over a substantial length thereof.
  • dampening members are resilient blocks.
  • dampening element is a noise-abating substance cast between said cover and said spindle rail.
