  • the pre-correction target-position command Pt which is a command for a not-yet-corrected position of the traverse guide 61
  • the post-correction target-position command Ps which is a command for a corrected position of the traverse guide 61
  • Factors that cause an actual position Pr of the traverse guide 61 to deviate by a relatively large degree from a target position Pi, which is an ideal position of the traverse guide 61, in conventional yarn winding devices are described below.
  • FIG. 2 in (a), shows a relationship between the pre-correction target-position command Pt and the post-correction target-position command Ps for the traverse guide 61, and in (b), shows a change in the rotational speed Bv of the bobbin B with time.
  • FIG. 3 in (a), shows a relationship between the actual position Pr and the target position Pi of the traverse guide 61 in the conventional yarn winding device, and in (b), shows a change in the rotational speed Bv of a bobbin in the conventional yarn winding device with time.
  • the pre-correction target-position command Pt for the traverse guide 61 specifies how the position of the reciprocating traverse guide 61 should change with time.
  • the pre-correction target-position command Pt for the traverse guide 61 has been determined in advance in the form of the relationship with the rotational speed Bv of the bobbin B.
  • the pre-correction target-position command Pt for the traverse guide 61 is updated by the traverse control unit 81, serving as a target-position-command determining unit, on a per-position-control-cycle basis of the traverse guide 61 to the pre-correction target-position command Pt that corresponds to the rotational speed Bv of the bobbin B.
  • the pre-correction target-position command Pt for the traverse guide 61 is configured such that a traverse rate of the traverse guide 61 increases as the rotational speed Bv of the bobbin B increases.
  • the pre-correction target-position command Pt for the traverse guide 61 is configured such that the traverse guide 61 reciprocates along a substantially sinusoidal path, of which center is at the origin O, between one end Be and the other end Be of the bobbin B (package P).
  • the post-correction target-position command Ps for the traverse guide 61 which is obtained from the pre-correction target-position command Pt for the traverse guide 61 and the target-position correction amount Cp, specifies how the position of the reciprocating traverse guide 61 should change with time.
  • the post-correction target-position command Ps for the traverse guide 61 is a command obtained by correcting the pre-correction target-position command Pt for the traverse guide 61 with the target-position correction amount Cp.
  • the post-correction target-position command Ps for the traverse guide 61 has a phase shift relative to the pre-correction target-position command Pt for the traverse guide 61. This causes the traverse guide 61 to follow a target path specified by the post-correction target-position command Ps, thereby canceling a response delay time and the like of the traverse-guide driving unit 62.
  • a first factor is that immediately after the state of the bobbin B has changed from the stopped state to the rotating state, the rotational speed Bv of the bobbin B is low, which makes it difficult to obtain an accurate value of the rotational speed Bv. More specifically, the rotational-speed detecting unit 73 obtains detection signals in response to the pits and projections of the pulse disk. Hence, when the rotational speed Bv of the bobbin B is low, or, in other words, when the rotational speed of the pulse disk is low, a cycle period of the detection signals is undesirably long.
  • the traverse control unit 81 controls the traverse-guide driving unit 62 according to the pre-correction target-position command Pt that corresponds to the calculated value, which differs from the actual value, of the rotational speed Bv of the bobbin B. This results in a deviation of the actual position Pr of the traverse guide 61 from the target position Pi.
  • a second factor is the response delay time of the traverse-guide driving unit 62 related to supply of electric power, which is generated based on a calculation result and supplied by the traverse control unit 81. More specifically, the traverse control unit 81 supplies, to the traverse-guide driving unit 62, electric power that depends on the pre-correction target-position command Pt that corresponds to the rotational speed Bv of the bobbin B. When the traverse rate is changed in response to a change in control signals for the pre-correction target-position command Pt and the like, the response delay time of the traverse-guide driving unit 62 also changes.
  • the response delay time of the traverse-guide driving unit 62 increases, resulting in a deviation of the actual position Pr of the traverse guide 61 from the target position Pi in some cases.
  • the reason why the yarn winding device 100 according to the first embodiment of the present invention is capable of reducing the deviation of the actual position Pr of the traverse guide 61 from the target position Pi in the acceleration winding period of the package P is specifically described below.
  • FIG. 4 in (a), shows relationships among the pre-correction target-position command Pt, the post-correction target-position command Ps, and the actual position Pr of the traverse guide 61, and in (b), shows a change in the rotational speed Bv of the bobbin B with time.
  • FIG. 5 in (a), shows a relationship between the actual position Pr and the target position Pi of the traverse guide 61 in the yarn winding device 100, and in (b), shows a change in the rotational speed Bv of the bobbin B with time.
  • the traverse control unit 81 serving as the target-position-command determining unit, obtains the rotational speed Bv of the bobbin B based on the detection signal fed from the rotational-speed detecting unit 73. More specifically, the traverse control unit 81 obtains the rotational speed Bv of the bobbin B on a per-position-control-cycle ( ⁇ t in (b) in FIG. 4 ) basis for the traverse guide 61 (see (b) in FIG. 4 ).
  • the traverse control unit 81 determines the target-position correction amount Cp by predicting a detection delay time of the rotational speed Bv of the bobbin B and a response delay time of the traverse-guide driving unit 62, and calculates the post-correction target-position command Ps based on the target-position correction amount Cp.
  • the traverse control unit 81 controls the traverse-guide driving unit 62 according to the post-correction target-position command Ps on the per-position-control-cycle ( ⁇ t in (b) in FIG. 4 ) basis.
  • the detection delay time of the rotational speed Bv of the bobbin B gradually decreases as the rotational speed Bv of the bobbin B increases.
  • the traverse control unit 81 can predict the detection delay time. More specifically, as illustrated in (b) in FIG.
  • the detection delay time of the rotational speed Bv of the bobbin B gradually decreases as the rotational speed Bv of the bobbin B increases.
  • the traverse control unit 81 can optimally calculate the post-correction target-position command Ps for the traverse guide 61 and control the driving of the traverse-guide driving unit 62 according to the post-correction target-position command Ps.
  • the yarn winding device 100 according to the first embodiment is capable of reducing the deviation of the actual position Pr of the traverse guide 61 from the target position Pi, thereby preventing the package P from becoming defective.
  • the response delay time of the traverse-guide driving unit 62 gradually increases as the rotational speed Bv of the bobbin B increases.
  • the traverse control unit 81 can predict the response delay time. More specifically, as illustrated in (a) in FIG.
  • the response delay time of the traverse-guide driving unit 62 gradually increases as the rotational speed Bv of the bobbin B increases.
  • the traverse control unit 81 can optimally calculate the post-correction target-position command Ps for the traverse guide 61 and control the driving of the traverse-guide driving unit 62 according to the post-correction target-position command Ps. More specifically, the traverse control unit 81 can control the driving of the traverse-guide driving unit 62 in a manner that the response delay time r1 of the traverse-guide driving unit 62 is the same as each of r2, r3, and r4. Accordingly, the yarn winding device 100 according to the first embodiment is capable of reducing the deviation of the actual position Pr of the traverse guide 61 from the target position Pi, thereby preventing the package P from becoming defective.
  • the yarn winding device 100 can prevent a deviation of the actual position Pr of the traverse guide 61 from the target position Pi by a large degree.
  • the yarn winding device 100 calculates the post-correction target-position command Ps for the traverse guide 61 and controls the driving of the traverse-guide driving unit 62 according to the post-correction target-position command Ps only when the rotational speed Bv of the bobbin B is increasing. This is because, when the rotational speed Bv of the bobbin B is increasing, the deviation of the actual position Pr of the traverse guide 61 from the target position Pi is likely to increase. Hence, the yarn winding device 100 according to the first embodiment can reduce the deviation of the actual position Pr of the traverse guide 61 from the target position Pi, thereby preventing the package P from becoming defective.
  • the yarn winding device 100 does not calculate the post-correction target-position command Ps for the traverse guide 61, but controls the driving of the traverse-guide driving unit 62 according to the pre-correction target-position command Pt when the rotational speed Bv of the bobbin B is constant or decreasing. This is because, when the rotational speed Bv of the bobbin B is constant or decreasing, the deviation of the actual position Pr of the traverse guide 61 from the target position Pi is less likely to increase. Hence, the configuration of the yarn winding device 100 related to control can be simplified.
  • a yarn winding device 200 according to a second embodiment of the present invention is capable of reducing the deviation of the actual position Pr of the traverse guide 61 from the target position Pi is specifically described below.
  • the yarn winding device 200 according to the second embodiment differs from the yarn winding device 100 according to the first embodiment in specifying the traverse rate rather than specifying how the position of the traverse guide 61 changes with time.
  • Constituent elements that are the same or similar in configuration with those of the yarn winding device 100 discussed above are denoted by like reference numerals and constituent elements that differ from those of the yarn winding device 100 are mainly discussed below.
  • FIG. 6 in (a), shows relationships among a pre-correction target-speed command Vt, a post-correction target-speed command Vs, and an actual speed Vr of the traverse guide 61, and in (b), shows a change in the rotational speed Bv of the bobbin B with time.

  • the traverse control unit 81 serving as a target-speed-command determining unit, obtains the rotational speed Bv of the bobbin B based on the detection signals received from the rotational-speed detecting unit 73. More specifically, the traverse control unit 81 obtains the rotational speed Bv of the bobbin B on a per-speed-control-cycle ( ⁇ t in (b) in FIG. 6 ) basis for the traverse guide 61 (see (b) in FIG. 6 ).
