Definitions

  • the present invention relates to a spinning machine that drafts a sliver, applies atwist to the drafted yarn, and winds the yarn into a rotary driven bobbin, and more particularly, to a spinning machine capable of measuring the tension of the yarn during spinning.
  • ring spinning machines are the most commonly employed type of spinning machine throughout the world, and can produce a yarn which has a true twist and is superior in quality to other types of yarn, both in terms of yarn strength and textural characteristics.
  • Ring spinning machines spin yarn at maximum yarn speeds of 20 to 30 meters per minute.
  • the present invention is a spinning apparatus that forms a spun yarn by applying a twist to a fiber bundle that has been drafted by a drafting mechanism, the twist applied through the rotation of a bobbin into which the spun yarn is wound, wherein the spinning apparatus is provided with a tension detection means for detecting the tension of the yarn between the drafting mechanism and the bobbin.
  • the spinning apparatus applies the twist to the yarn using a rotatable funnel that covers the bobbin, wherein the funnel is rotationally driven in synchronization with the bobbin.
  • the yarn tension detection means is comprised of a head unit that contacts and applies pressure against the yarn and a detector that determines the tension of the yarn.
  • the angle at which the yarn is bent at the head unit is between 130 degrees and 170 degrees.
  • the spinning apparatus shown in Figures 1 and 2 processes a yarn Y by drafting a sliver S with a drafting mechanism 101, applying a twist to the drafted yarn Y with a twisting mechanism 102, and then winding the yarn Y into a bobbin 6.
  • the drafting mechanism 101 is comprised (in order relative to the direction in which the yarn progresses) of a pair of back rollers 2, a middle roller unit 3 including a pair of apron rollers 3a, and a pair of front rollers 4. As the sliver S passes through the various rollers 2, 3, 4, it is drafted to a predetermined thickness.
  • the twisting mechanism 102 includes a funnel 5 that opens out to the downstream side of the yarn path and covers the bobbin 6, and a funnel holding unit 21 that holds the funnel 5 so that the funnel 5 can rotate freely.
  • the funnel 5 includes a funnel main body 5a .
  • the funnel 5 is held by the bearings 22, 22 of a shaft unit 5b that extends upward, and is held so as to be freely rotatable.
  • the funnel main body 5a is rotatable via a funnel driving motor 23 that is arranged inside the funnel holding unit 21.
  • the funnel driving motor 23 is comprised of a rotary magnet 25 that is fixedly attached to shaft unit 5b, and a stator coil 24 that is arranged around the rotary magnet 25 and is fixedly attached to the casing 21a of the funnel holding unit 21.
  • the bobbin 6 is formed integrally with a spindle 7, and is rotatable.
  • the spindle 7 is held by the bearings 9, 9 of a spindle holding unit 8, and is held so as to be fully rotatable.
  • the spindle 7 can be rotated by a spindle driving motor 10 arranged inside the spindle holding unit 8.
  • the spindle driving motor 10 is comprised of a rotary magnet 12 fixedly attached to the spindle 7, and a stator coil 11 fixedly attached to the casing 8a of the spindle holding unit 8, the coil 11 arranged so as to face the rotary magnet 12.
  • the spindle 7 and the shaft 5b of the funnel 5 are arranged coaxially, and the spindle 7 and the funnel 5 are each axially rotated by their respective driving motors 10, 23.
  • a hole 5c is formed in the axial direction in the shaft 5b of the funnel 5.
  • the hole 5c allows the upper circumferential surface of the shaft 5b to communicate with an opening 5d formed in the upper surface of the funnel main body 5a.
  • the yarn Y that has been processed by the draft mechanism 101 passes through the hole 5c at the top of the funnel 5, exits the funnel main body 5a at the openning 5d, is passed around the periphery of the funnel 5a, and is taken up into the bobbin 6.
  • the sensor 15 detects the tension of the yarn during spinning.
  • the bobbin 6 is comprised such that it is vertically moveable relative to the funnel 5.
  • the rotary speeds of the funnel driving motor 23 and the spindle driving motor 10 are individually controlled by a controller 14 that is connected to both the funnel driving motor 23 and spindle driving motor 10.
  • the control 14 controls the rotary speeds of the funnel driving motor 23 and spindle driving motor 10 such that the rotation of the funnel 5 and bobbin 6 is synchronized.
  • the rotary speeds of the funnel 5 and the bobbin 6 are synchronized so that even if the rotary speed increases very quickly when rotary drive is initiated, or if spinning is performed at high rotary speeds, the tension of the yarn Y between the bobbin 6 and the funnel 5 does not increase severely. This helps to prevent a yarn breakage, and allows a fine yarn to be spun at high speeds.
  • the yarn Y that is produced has the same strength and textural characteristics as a ring-spun yarn produced by the ring spinning machine.
  • the rotation of the bobbin 6 and the funnel 5 are driven independently by the spindle driving motor 10 and the funnel driving motor 23, respectively, thus allowing independent control of the rotary speed of the bobbin 6 and the funnel 5 during a normal operation.
  • This allows the difference in the rotary speed between the bobbin 6 and the funnel 5 to be set arbitrarily. Consequently, this allows the type of twist imparted to the yarn Y and the textural characteristics of the yarn Y to be changed at will.
  • the tension sensor 15 is arranged between the front rollers 4 of the draft mechanism 101 and the funnel 5, which is arranged on the drafting mechanism 101 side of the bobbin 6.
  • the tension sensor 15 contacts and receives pressure from the yarn Y, thus creating a bend in the yarn path having an angle ⁇ .
  • the tension sensor 15 is comprised of a head unit 52 contacting the yarn Y that is formed of a ceramic or the like, a sensor main body 51 that senses the tension of the yarn Y, and a connecting rod 53 that connects the sensor main body 51 with a head unit 52.
  • a groove 52a is formed on a surface of the head unit 52, into which slideably fits the yarn Y.
  • the yarn Y contacts and applies pressure to the head unit 52, and applies force in the direction of contact (as indicated by the arrow in Figures 4 and 5), and this force is imparted through the connecting rod 53 to the sensor main body 51.
  • a sensing instrument such as a strain gauge or the like arranged inside the sensor main body 51 then detects the force.
  • the force applied against the head unit 52 by the contact pressure of the yarn Y is detected by the sensor main body 51, enabling the detection of the tension of the yarn Y.
  • the tension sensor 15 is comprised of the sensor main body 51 and the head unit 52, and by permitting the yarn Y to run freely along the head unit 52, the head unit 52 does not interfere with the transmission of the twist imparted to the yarn Y, thereby allowing accurate detection of the yarn tension.
  • the contact pressure of the yarn Y against the head unit 52 will be small and insufficient, preventing accurate detection of the yarn tension.
  • the contact pressure of the yarn Y against the head unit 52 will be too great, and the twist imparted to the yarn Y by the twisting mechanism 102 may not be transmitted past the head unit 52 to the drafting mechanism 101.
  • the tension sensor 15 is arranged between the draft mechanism 101 and the funnel 5 such that the angle ⁇ at which the yarn bends is between 130 degrees and 170 degrees, such that the twist imparted to the yarn Y extends to the drafting mechanism 101 side, thereby enabling the tension of the yarn Y to be accurately detected.
  • the tension of the yarn Y during by spinning in other words, the spinning tension can be detected during the high-speed spinning, thus enabling the relationship between the spinning tension and the physical characteristics of the yarn Y that is produced to be determined.
  • the detected tension value can be used to perform feedback control on the rotary speeds of the funnel 5 and the bobbin 6 (or spindle 7) such that the rotary speeds are adjusted according to the tension of the yarn Y, thereby performing the equivalent of a quality control check, enabling the manufacture of yarn Y that is of uniform quality.
  • the tension sensor 15 in the spinning machine of the present invention need not necessarily be applied only in the funnel-type spinning apparatus disclosed in the embodiments described herein, but may also be applied in a ring spinning machine.
  • the present invention would allow the yarn to be manufactured with less chance of yarn breakage, allow the twist to be reliably transmitted to the draft mechanism side of the yarn path, and allow the tension of the yarn Y to be accurately detected.
  • the present invention offers the following benefits.
  • a spinning apparatus that applies a twist to a fiber bundle that has been drafted by a drafting mechanism and forms a spun yarn through the rotation of a take-up bobbin is provided with a tension detection means for detecting the tension of the yarn at a location between the drafting mechanism and the bobbin.
  • the tension detection means does not interfere with the transmission of the twist imparted by the twisting mechanism, and thereby allows the tension of the yarn to be measured during spinning.
  • the tension detection means can be used to detect the tension of the yarn at all times during spinning, and by detecting the rotary speed of the funnel and the bobbin (or alternatively, the spindle), the detected tension value can be used to perform feedback control on the rotary speeds of the funnel and the bobbin (or spindle) such that the rotary speeds are adjusted according to the tension of the yarn, thereby performing the equivalent of a quality control check, enabling the manufacture of yarn that is of uniform quality.
  • the spinning apparatus applies a twist to the yarn using a freely rotatable funnel that covers the bobbin, and since the rotation of the funnel and the rotation of the bobbin are synchronized, the yarn can be spun at high speeds with less chance of breakage, and the spinning tension of the yarn Y can be measured without interfering with the transmission of the twist imparted to the yarn by the twisting mechanism.
  • the tension detection means is comprised of a head unit that contacts and receives pressure from the yarn, and a sensor main body that determines the tension of the yarn. This construction does not interfere with the transmission of twist imparted to the yarn, and allows the tension of the yarn to be detected accurately.
  • the angle of the yarn where it contacts the head unit is between 130 degrees and 170 degrees. This enables the twist imparted to the yarn by the twisting mechanism to reliably extend to the draft mechanism side of the detecting means, thereby enabling accurate detection of yarn tension.
