Definitions

  • the present invention primarily relates to an air spinning machine. More specifically, the present invention relates to a configuration for calculating a consumed sliver length.
  • a configuration is conventionally known in which a process of calculating a consumed sliver length, etc. is executed for the purpose of efficient replenishment of a sliver which is a raw material.
  • This type of textile machine is disclosed in Japanese Examined Patent Application Publication No. H2-29770 (1990 ), Japanese Examined Utility Model Application Publication No. H7-40536 (1995 ), and Japanese Unexamined Patent Application Publication No. H11-279862 (1999 ).
  • Japanese Examined Patent Application Publication No. H2-29770 (1990 ) discloses a production management device for an open-end fine spinning machine or the like.
  • the production management device calculates a consumed sliver length, and if the consumed sliver length reaches a pre-set value, notifies a worker of it.
  • the production management device calculates the consumed sliver length by detecting rotation of a drive shaft that drives a winding drum or a draw-off roller.
  • Japanese Examined Utility Model Application Publication No. H7-40536 (1995 ) discloses an automatic sliver splicing apparatus that splices a beginning of a sliver to an end of a sliver.
  • the automatic sliver splicing apparatus detects a terminal of a sliver by using a phototube type sensor.
  • Japanese Unexamined Patent Application Publication No. H11-279862 (1999 ) relates to a sliver can replacement system that supplies a sliver can accommodating a sliver to a spinning machine.
  • the sliver can replacement system includes a sliver can replacement management device.
  • the sliver can replacement management device calculates a next timing for sliver can replacement based on data of, for example, the amount of a sliver accommodated in the sliver can, a spinning speed in each spinning unit, and a spun yarn count.
  • EP 1 347 085 A2 discloses a spinning unit having an individual-spindle-driving motor to drive rollers of a draft device.
  • the motor is a stepping motor configured to have its rotations speed controlled by a central control device.
  • Japanese Examined Patent Application Publication No. H2-29770 (1990 ) detects rotation of the drive shaft that drives the winding drum or the draw-off roller which is arranged downstream of a spinning apparatus in a fiber travelling direction. This cannot detect a precise consumed sliver length. For example, when a fiber loss occurs in the spinning apparatus, a consumed sliver length that is based on the fiber loss cannot be reflected in an overall consumed sliver length. In addition, when a yarn is partially removed for the purpose of preventing a yarn defect or the like from being wound around a package, it is difficult that a consumed sliver length based on the yarn having this removal is reflected in an overall consumed sliver length. Japanese Examined Utility Model Application Publication No.
  • H7-40536 (1995 ) is a configuration that detects a sliver terminal, and is not a configuration that calculates a specific consumed sliver length.
  • a timing for sliver can replacement is calculated based on a set spinning speed, and therefore the timing for sliver can replacement may not be precisely calculated.
  • a primary object of the present invention is to provide a configuration that precisely calculates a consumed sliver length in an air spinning machine for air spinning.
  • a first aspect of the present invention provides an air spinning machine having the following configuration.
  • the air spinning machine includes a conveyor roller, an air spinning device, an electric motor, and a control part.
  • the conveyor roller feeds a sliver.
  • the air spinning device produces a spun yarn by twisting a fiber bundle made from the sliver with airflow.
  • the electric motor drives the conveyor roller, and has its rotation amount controlled in accordance with a command signal.
  • the control part calculates a consumed length of the sliver based on the command signal.
  • the consumed length of the sliver can be calculated without using a sensor that directly detects the rotation amount of the conveyor roller or the like. This can avoid a cost increase and complication of the configuration of the air spinning machine which may otherwise be caused by addition of a sensor. Moreover, the calculation is performed based on the rotation amount of the conveyor roller that feeds the sliver, and therefore the consumed length of the sliver can be more precisely calculated as compared to when the consumed length of the sliver is calculated based on, for example, a spinning speed.
  • the air spinning machine includes a plurality of spinning units each having at least the conveyor roller and the air spinning device.
  • control part calculates at least either a remaining time before the sliver runs out in any of the plurality of spinning units or a total quantity of sliver required to be replenished in a predetermined time, based on information of an initial length of the sliver and a fiber travelling speed.
  • replenishment of the sliver can be implemented efficiently.
  • the air spinning machine is configured as follows.
  • the air spinning machine includes a first display part that displays information about the plurality of spinning units.
  • the first display part displays at least either the remaining time or the quantity calculated by the control part.
  • the air spinning machine is configured as follows.
  • the air spinning machine includes an alarm part individually disposed in each of the spinning units, the alarm part being configured to be switchable between an alarm state and a non-alarm state.
  • the alarm part switches to the alarm state in a case where the spinning unit where the alarm part is disposed satisfies at least either a condition that a remaining length of the sliver in the spinning unit be equal to or less than a predetermined length or a condition that a remaining time for which the spinning unit is able to perform spinning by using the currently remaining sliver be equal to or less than a predetermined time.
  • the air spinning machine is configured as follows.
  • the air spinning machine includes a second display part individually disposed in each of the spinning units, the second display part being capable of displaying at least a numeral.
  • the second display part displays at least either a remaining length of the sliver or a remaining time before the sliver runs out in the spinning unit where the second display part is disposed.
  • the air spinning machine includes a transmitter that transmits, to outside, at least either the quantity of sliver required to be replenished or a timing when replenishment of the sliver is required, for the plurality of spinning units.
  • the air spinning machine is configured as follows.
  • the air spinning machine includes a guide device that guides the sliver, and a feed device that forms the fiber bundle from the sliver guided by the guide device and feeds the fiber bundle to the air spinning device.
  • the conveyor roller is provided in the guide device or in the feed device, or the conveyor roller is disposed between the guide device and the feed device with respect to a fiber travelling direction.
  • the air spinning machine is configured as follows.
  • the control part executes a process of calculating a remaining length of the sliver based on the consumed length of the sliver.
  • the control part is capable of performing a control that stops the feed device for each of the spinning units based on the calculated remaining length of the sliver, and in this control, the control part stops the feed device in such a manner that an upstream end portion of the sliver in the fiber travelling direction is located at a position upstream of the guide device.
  • control part stores a stop length that is a threshold for the remaining length of the sliver, and stops the feed device upon the remaining length of the sliver becoming equal to or less than the stop length.
  • This configuration can prevent a portion of the sliver near its terminal, which is likely to have a poor quality, from being used to produce the spun yarn.
  • the air spinning machine is configured as follows.
  • the feed device is a draft device that forms a fiber bundle by drafting a sliver guided by the guide device.
  • the conveyor roller is formed of a plurality of draft rollers and a plurality of facing rollers included in the draft device.
  • the air spinning machine includes a draft device cradle that presses the plurality of facing rollers included respectively in adjacent two of the spinning units to the plurality of draft rollers, or that presses the plurality of draft rollers included respectively in adjacent two of the spinning units to the plurality of facing rollers.
  • the control part stops the draft device of one of the two spinning units while the draft device cradle is pressing the draft rollers or the facing rollers and the draft devices of the two spinning units are holding the slivers.
  • one of the spinning units whose draft device is stopped with the sliver held thereon, can resume the spinning operation without cancelling the pressing applied by the draft device cradle. Since one of the spinning units can resume the spinning operation while the other of the spinning units keeps performing the spinning operation, a reduction in production efficiency can be prevented.
  • the air spinning machine is configured as follows.
  • the air spinning machine includes a sliver storage part and a package placement part.
  • the sliver storage part stores the sliver to be guided by the guide device.
  • the package placement part a package obtained after the spun yarn spun by the air spinning device is wound is placed.

  • the sliver storage part is arranged on the side opposite to the passage relative to the spinning unit, which usually would make it difficult for an operator working on the passage to visually observe the remaining length of the sliver.
  • replenishment of the sliver is often implemented after the sliver runs out, and therefore the production efficiency is reduced.
  • adoption of the present invention can make it easy for an operator to grasp the consumed length of the sliver even in the above-described layout. Consequently, replenishment of the sliver is more likely to be implemented before the sliver runs out. Accordingly, the production efficiency can be increased.
  • the air spinning machine is configured as follows.
  • the air spinning machine includes a sliver storage part that stores the sliver to be guided by the guide device.
  • a sensor for detecting the sliver is not provided between the sliver storage part and the air spinning device.
  • a sensor for detecting a rotation amount of the conveyor roller or a length over which the sliver is fed is not provided between an upstream end portion of the feed device and an upstream end portion of the guide device.

  • the hollow guide shaft member guides the fiber bundle twisted in the spinning chamber to outside.
  • the air spinning machine of the above-described type has a high spinning speed, and therefore a consumed length of a sliver in a spinning unit whose spinning operation is temporarily stopped for some reason is significantly smaller than consumed lengths of slivers in the other spinning units .
  • a timing for replenishing the sliver largely differs among the plurality of spinning units. Accordingly, the effects of the present invention can be exerted more effectively.
  • the air spinning machine includes a reset operation part that enables implementation of an operation for resetting a result of calculation of the consumed length of the sliver calculated by the control part.
  • a second aspect of the present invention provides a display control method for controlling a display of sliver replenishment information, having the following configuration.

  • the fiber bundle 8 drafted by the draft device 7 is introduced through the fiber introducing port 61a, and is guided into the spinning chamber 62 while being wrapped around the guide needle 61b.
  • the air spinning device 9 is configured such that air is jetted from the nozzle 63 into the spinning chamber 62 to apply a swirling airflow to the fiber bundle 8 in the spinning chamber 62. It may be acceptable that the guide needle 61b is omitted and a downstream end portion of the fiber guide 61 has a function as the guide needle 61b.
  • the second holder 70 includes a hollow guide shaft member 71.
  • the hollow guide shaft member 71 has a yarn passage 72 formed in its shaft center. Due to the air jetted from the nozzle 63, the rear ends of fibers of the fiber bundle 8 swing around the distal end of the hollow guide shaft member 71.

Rotating the yarn storage roller 26 at a predetermined rotation speed with the spun yarn 10 wound on the outer peripheral surface of the yarn storage roller 26 enables the spun yarn 10 to be drawn out from the air spinning device 9 and conveyed downstream at a predetermined speed. Since the spun yarn 10 can be temporarily stored on the outer peripheral surface of the yarn storage roller 26, the yarn storage device 12 is able to function as a buffer of sorts.

  • the cradle arm 46 rotatably supports the bobbin 48 for winding the spun yarn 10.
  • the winding drum 98 receives a drive force transmitted from a winding drum drive motor (not shown), to be rotated while being in contact with an outer peripheral surface of the package 28 or the bobbin 48.
