Definitions

  • the present invention relates to a textile machine including a plurality of yarn processing units. More particularly, the present invention relates to a configuration for displaying an operation state of the yarn processing unit. The present invention also relates to a configuration for notifying an error occurred in the yarn processing unit.
  • a conventional textile machine such as a spinning machine including a plurality of spinning units and an automatic winder including a plurality of winder units, includes a plurality of yarn processing units.
  • the textile machine of this type generally includes a central management device (machine control device) that collectively manages information relating to each of the yarn processing units.
  • a central management device machine control device
  • Japanese Unexamined Patent Application Publications No. H5-70040 Patent Document 1
  • No. H6-128823 Patent Document 2
  • No. H7-90733 Patent Document 3
  • a textile machine including a central management device that centrally manages a plurality of yarn processing units.
  • various pieces of information such as an operation efficiency of each of the yarn processing units and an error occurrence state can be displayed on a monitor.
  • Patent Document 4 In a winder unit disclosed in German Patent Application Publication No. 102006045237 (Patent Document 4), a panel is provided on a front surface of each of the winder units, and a plurality of single images schematically illustrating error occurrence factors are displayed on each panel. When an error occurs, the winder unit of Patent Document 4 notifies an error occurred section by lighting the single image that corresponds to the occurred error.
  • a yarn winding unit that meets a prescribed condition may be extracted by performing a prescribed operation from the central management device.
  • an operator performs an appropriate operation to extract (select) a yarn processing unit having an operation efficiency lower than an average of the entire machine, and to display the extracted yarn processing unit on the monitor. Accordingly, the operator can check the monitor, and then walk to the place where the yarn processing unit in need of maintenance work is provided, and perform the maintenance work.
  • the operator performs a prescribed operation from the central management device to display the yarn processing unit with a low operation efficiency on the monitor. Therefore, when the operation efficiency of a certain yarn processing unit decreases during the operation of the textile machine, the operator cannot realize the decrease in the operation efficiency of the yarn processing unit until the operator performs the prescribed operation from the central management device and checks the monitor. As a result, the operator could not confirm the yarn processing unit with a decreased operation efficiency at an early stage to perform an appropriate operation.
  • the winder unit disclosed in Patent Document 4 displays the error occurrence factors or the like on the front panel. Therefore, when an error occurs, in order to obtain information about the error, the operator can immediately confirm the error occurring in the yarn processing unit without checking the monitor of the central management device.
  • the winder unit disclosed in Patent Document 4 displays information relating to the yarn processing unit only when an error occurs in such a yarn processing unit. As a result, the operator could not confirm a current state of the yarn processing unit that is during operation.
  • Patent Document 5 discloses a structure for displaying an error occurred section in a bobbin transportation device used in an automatic winder.
  • An error display device disclosed in Patent Document 5 is provided with a light-emitting diode at an appropriate position on a panel illustrating a schematic view of the bobbin transportation device. By lighting the light-emitting diode that corresponds to the error occurred section, the error occurred section is displayed.
  • the operator when an error occurs in any of the plurality of yarn processing units, through a method of lighting a lamp of the yarn processing unit in which an error has occurred, the operator is notified of the yarn processing unit that needs a maintenance work. Accordingly, the operator can confirm the location of the yarn processing unit in which an error has occurred, and goes to the location where such yarn processing unit is provided to perform an appropriate maintenance work.
  • the operator has been judging, through own experience, which specific section in the yarn processing unit needs a maintenance work. Therefore, there were cases in which the operator performed a maintenance work on a section that is different from the error occurred section, or used longer hours than required.
  • each yarn processing unit includes a seven-segment display or the like, and by displaying an error code in numbers and/or in alphabets on the display, an operator is notified of contents of an error occurred in the yarn processing unit.
  • the operator cannot promptly perform an appropriate operation unless the operator knows a correspondence relation between the error code and an error occurred section (or the error contents). Even if the operator fully knows the error code, the operator cannot intuitively realize a specific error occurred section in the yarn processing unit. As a result, problems arise in that it is troublesome to check the contents indicated by the error code and that an operator may check an irrelevant section. Thus, the operation efficiency was low, and a large burden was posed on the operator.
  • Patent Document 6 discloses an automatic winder that visually displays error occurrence factors on a monitor that is connected with a central management device. With this structure, an operator can intuitively learn error contents as compared with the above-described error code display. Patent Document 6 describes that even an inexperienced operator can easily confirm a section that needs a maintenance work and contents of the error, and thus can promptly perform maintenance work.
  • Patent Document 6 when an error occurs in the yarn processing unit, the operator once goes to the central management device to obtain information on the error occurred section or the like, and then checks the display on the monitor. After printing the displayed contents on a paper, the operator is required to go back to such yarn processing unit to perform maintenance work.
  • the automatic winder disclosed in Patent Document 6 can display on the monitor, a plurality of yarn processing units that have a great number of error occurrences.
  • the operator needs to go back and forth several times between the central management device and the yarn processing unit and check the display on the monitor.
  • the displayed contents are printed on the paper, in a situation where a plurality of operators are working, an operator who does not have the paper cannot know the error occurred section, and the operators cannot concurrently perform the maintenance work.
  • Patent Document 4 since each of the units is provided with the panel, the operator does not need to go to the central management device each time to check the monitor or does not need to check the printed paper. Therefore, the operator can promptly confirm the error contents.
  • the single images of the above Patent Document 4 are merely a substitute for the error code display, and an operator cannot intuitively confirm easily a correspondence relation between the display of the single images and the error occurred section.
  • the error contents are schematically illustrated by the single images, the operator cannot promptly understand the error occurred section by looking at the single images.
  • the operator is still required to know in advance the correspondence relation between the single images and the error occurred section.
  • depending on graphic contents of the single images there are cases where the operator cannot accurately understand the error contents even by looking at the graphics. As a result, an inexperienced operator cannot promptly perform an appropriate operation.

  • the standard operation state is an average value of the operation states of the plurality of yarn processing units of the textile machine. Accordingly, the operator can easily confirm the operation state of the yarn processing unit is displaced in which direction from the average value. Moreover, since the average value is used as a central level of the level display, a comparison can be easily made with an operation state of other yarn processing units.
  • the standard operation state may be a prescribed set value.
  • the operator can easily confirm the operation state of the yarn processing unit is displaced in which direction from the set value.

  • the above-described textile machine further includes a control section that controls the yarn processing unit.
  • the control section includes a determining section and an identifying section.
  • the determining section receives a signal from the yarn processing unit and determines whether or not the error has occurred in accordance with the received signal.
  • the identifying section identifies the error occurred section.
  • the control section carries out the display on the overall view display section by identifying the error occurred section based on a determination of the determining section and an identification of the identifying section.
  • the control unit determines a presence or an absence of the error, and identifies the error occurred section. Accordingly, the error occurred section can be properly displayed and identified in the overall view display section.
  • the overall view display section includes a plurality of luminous sections arranged near the overall view.
  • the control section can carry out the display by identifying a section that corresponds to the luminous section within the overall view. Accordingly, the error occurred section can be displayed and identified through a simple structure.
  • the overall view display section includes the plurality of luminous sections arranged within the overall view.
  • the control section can carry out the display by identifying the section that corresponds to the luminous section within the overall view. Accordingly, the operator can more intuitively confirm the error occurred section.
