Definitions

  • the present invention relates to a method and device for controlling winding of a tubular knitted fabric produced by a circular knitting machine.
  • a circular knitting machine includes: a knitting portion which rotates a cylinder including knitting needles received in needle grooves, by drive of a motor and feeds yarns to the knitting needles to produce a tubular knitted fabric; and a winding mechanism portion which winds the tubular knitted fabric produced by the knitting portion.
  • a servo motor which is accurately controllable at a high speed is often used for driving a winding roller, and control of winding the knitted fabric is performed by providing a command pulse synchronized with operation of the knitting portion, to a servo driver.
  • a torque control mode (whereby output torque of the servo motor is controlled at a constant value)
  • a position control mode whereby a rotation angle of the servo motor is controlled at a constant value) are often used.
  • the amount of a knitted fabric produced per one rotation of a cylinder of a knitting portion may change during operation due to a change in a knitting condition of the knitted fabric such as a knit structure, the number of stitches, knitting timing, a used yarn, or the like.
  • a production amount of a knitted fabric of all knit is larger than that of a knitted fabric with a knit structure including welt or tuck, and the production amount increases as the number of stitches increases.
  • Patent Document 1 By keeping the output torque of a torque (servo) motor constant, the torque motor is controlled such that constant winding tension is maintained to perform automatic torque adjustment, even when the production amount of a knitted fabric is changed.
  • a stop step defect is where a 'line-like step' is formed in a produced cylindrical knitted fabric along the circumference of the knitted fabric at the time of stop of operation or a lateral step which is a knitting defect in which a helical step is formed in the knitted fabric during operation.
  • the position control mode is a mode whereby a knitted fabric production amount corresponding to the rotation angle of the servo motor per one rotation of the cylinder of the knitting portion, is manually preset (i.e. movement amount data per one pulse of a command pulse number to the servo motor is manually preset), and this is provided as position control data to the servo motor driver for winding a knitted fabric at constant winding tension.
  • a knitted fabric is constantly wound in an amount corresponding to the position control data during operation.
  • the position control mode when used as it is, it may be possible to respond to a slight change in the production amount of the knitted fabric in some cases, but, for example, as in garment length knitting, when the production amount of the knitted fabric greatly changes during operation due to a change in a knit structure or the like which is caused by the electronic needle selection function, an allowable range where it is possible to respond to the change by adjustment of a winding amount may be exceeded.
  • the winding tension of the knitted fabric extremely decreases or increases, and the quality of the knitted fabric is adversely affected by a knitting scar, or the operation may be disabled and not allowed to continue due to yarn breakage or an alarm of a yarn feeding device, whereby it may not be possible to appropriately and stably produce a knitted fabric and thus winding thereof is also not possible.
  • One purpose of the present invention is to provide a winding control method and device for a circular knitting machine which allow a knitted fabric to be wound at appropriate and stable winding tension in a position control mode even when a production amount of the knitted fabric greatly changes during operation.
  • a winding control method and device for a circular knitting machine winds a tubular knitted fabric produced by a knitting portion on the basis of set knitting conditions for the knitted fabric, by a winding mechanism portion (including a winding roller and a winding servo motor for roller drive) and controls the winding mechanism portion by a winding control portion.
  • control is maintained whilst the production amount data is changed in response to a change in the specific knitting data affecting a production amount of the knitted fabric during operation, or of knitting data regarding the knitting conditions.
  • the position control data corresponding to the winding amount of the knitted fabric is set such that the position control data changes in synchronization with the change in the production amount data.
  • the specific knitting data includes at least one of knit structure data, stitch number data, knitting timing data and yarn used data and a change in the production amount data (corresponding to a change in the specific knitting data) is previously stored and the change in the production amount data and the change in the position control data are synchronized.
  • the changed position control data is then set on the basis of the change in the specific knitting data allowing a rapid response and enabling a more appropriate and stable winding of the knitted fabric.
  • the specific knitting data is set per one course of a knit structure, that is, per one row in a lateral direction of the knit structure. Therefore, it is possible to appropriately and stably wind the knitted fabric for each course where there is a change in the production amount of the knitted fabric.
  • a change in knitting operation data corresponding to a change in the specific knitting data of the knitting conditions is previously stored; the knitting operation data and pre-defined data corresponding to the production amount data are collated; production amount data is obtained from matched pre-defined data; the production amount data is changed by repeating this, and the position control data is set such that the position control data changes in synchronization with the change in the production amount data.
  • the pre-defined data is paired with the knitting operation data and has previously been set as data to be collated with the knitting operation data.
  • the collation of the knitting operation data and the pre-defined data is used instead of the above correspondence between the change in the production amount data and the change in the position control data and it is possible to cause the production amount and the winding amount of the knitted fabric to coincide with each other by utilizing the configuration of an existing device which is not configured with specifications which allow setting of production amount data, as it is.
  • the knitting operation data comprises of the rotation speed of the knitting portion. Therefore, it is possible to more simply set the position control data with respect to a change in the specific knitting data.
  • the rotation speed data and the pre-defined data are collated for each course of a knit structure. If the rotation speed data has not altered, setting of the production amount data and the position control data is kept as it is without obtaining production amount data corresponding to the matched pre-defined data and synchronizing the production amount data and the position control data and collation is performed for a next course.
  • four types of the pre-defined data are set; the first is the pre-defined data of an inching speed; the second is the pre-defined data of a low speed i.e. lower than the first data; the third is the pre-defined data of an intermediate speed higher than the first data and the fourth is the pre-defined data of a high speed i.e. higher than the third data. Therefore, it is possible to more simply set the position control data with respect to a change in the specific knitting data.

  • a compensation program which provides a command to the winding mechanism portion 3 to increase/decrease a winding amount (earlier or later by several pulses) in order to compensate for a difference between a production amount and a winding amount of a knitted fabric.
  • Such differences can be caused by the magnitude of a change in the production amount of the knitted fabric which is caused when the winding amount is increased/decreased simultaneously with a change in the knit structure or the like; and timing when the servo driver 10 receives the position control data.
  • control is performed in which:
  • a winding control device of a second embodiment will be described.
  • the overall control portion 8 unlike the first embodiment in which the overall control portion 8 directly synchronizes the production amount data 15 and the position control data 18 to substantially simultaneously perform control of knitting condition setting and control of winding condition setting, in the second embodiment, an existing device to which production amount data does not correspond is utilized as it is, and control of knitting condition setting and control of winding condition setting are separately performed.

  • the configuration of the existing device is utilized in the second embodiment as it is.
  • the knit structure data or such like has a large data volume and it is difficult to collate such data; it also takes time and effort to create pre-defined data.
  • collation of the predefined data and the knitting operation data such as the rotation speed data of the knitting portion is used instead of the correspondence between the production amount data and the position control data, the existing device is simply used as it is, and the production amount and the winding amount of the knitted fabric are caused to coincide with each other.
  • the existing device is configured with specifications which allow the rotation speed data to be inputted to a data file, and the rotation speed data changes in response to a change in the specific knitting data, which responds to a change in a production amount of a knitted fabric.

  • the device reads the rotation speed data corresponding to the knit structure data of the present one course (step T3) and confirms whether the rotation speed data has changed from the rotation speed data of the last course in response to a change in the specific knitting data 14 (step T4). If the rotation speed data has not changed, the device does not change the production amount data and the position control data (step T7-2) and proceeds to step T3. If the rotation speed data has changed, the device performs collation to determine whether the rotation speed data is predefined data which is set as "high speed” (step T5-1). If the rotation speed data is "high speed", the device obtains the production amount data corresponding to the predefined data (step T6-1).
  • the device performs collation to determine whether the rotation speed data is predefined data which is set as “intermediate speed”, "inching”, or “low speed” (step T5-2, T5-3, or T5-4), and if matched, the device obtains the corresponding production amount data (step T6-2, T6-3, or T6-4).
