Therefore, while the device (the doffing device 17, the package shutter 51, the package conveyor 52, the supply device 3, the bobbin conveyor 4, and the preparation device 8) whose operation state is displayed on the operation state display panel 80 is in operation, the segment display section 81 may perform the rotation display.
  • the package conveyor 52 and the bobbin conveyor 4 convey the package 15 or the yarn supplying bobbin 12 by the rotation of the pulley, affinity with the rotation display is high. Therefore, the operator who looks at the rotation display can intuitively grasp that the package conveyor 52 or the bobbin conveyor 4 is in operation.
  • a direction of the change in the rotation display of the segment display section 81 of the operation state display panel 80 provided to the package conveyor 52 corresponds to a driving direction (rotation direction) of the package conveyor 52.
  • FIGS. 3 and 6 A specific description will be given with reference to FIGS. 3 and 6 .
  • FIG. 3 when the operator located in front of the operation state display panel 80 looks at the package conveyor 52, the package conveyor 52 is being rotationally driven clockwise as indicated by an arrow.
  • the rotation display of the segment display section 81 similarly changes clockwise. Accordingly, since the affinity between the driving of the package conveyor 52 and the display of the segment display section 81 is high, the operator can more intuitively grasp the operation of the package conveyor 52.
  • the rotation display is performed using the three seven-segment displays, but the rotation display can be performed in a similar procedure even when one, two, or four or more seven-segment displays are used.
  • FIG. 7 is a view illustrating that vertical movement display is performed by lighting on/off each segment of the segment display section 81.
  • the seven-segment display includes three horizontal bar-shaped segments arranged vertically. Therefore, by switching light on/off of the horizontal bar-shaped segments, it is possible to perform display (vertical movement display) in which a lighted portion appears to move up and down. Specifically, first, a horizontal bar-shaped segment located at the uppermost (or lowermost) is lighted on. Thereafter, while the horizontal bar-shaped segment located at the uppermost (or lowermost) is lighted off, a horizontal bar-shaped segment located at a center is lighted on.
  • the segment display section 81 can perform the vertical movement display. Further, as illustrated in FIG. 7 , even when the light on/off pattern is switched, the number of segments that are lighted on is the same (the number of lighted-on segments is always three in FIG. 7 ).
  • the segment display section 81 includes the three seven-segment displays arranged side by side in the lateral direction. Therefore, by lighting on/off the horizontal bar-shaped segments of each of the three seven-segment displays at the same timing, the segment display section 81 can perform the vertical movement display using the three seven-segment displays.
  • the vertical movement display is used for movement of some object from the top to the bottom or from the bottom to the top. Therefore, for example, affinity with the operation of the package shutter 51 (switching between the first state and the second state) is high.
  • the operation state display panel 80 illustrated in FIG. 3 displays operation states of both the package shutter 51 and the package conveyor 52. Therefore, the operation state display panel 80 is required to distinguish and display whether the package shutter 51 is in operation or the package conveyor 52 is in operation. Therefore, the operation state display panel 80 performs the vertical movement display when the package shutter 51 is in operation, and performs the rotation display when the package conveyor 52 is in operation. By selectively using the plurality of types of display in this manner, the operation states of the plurality of devices can be displayed on one operation state display panel 80.
  • the segment display section 81 when the operator instructs collection of the package 15, the segment display section 81 first performs the vertical movement display. Thereafter, the segment display section 81 performs the rotation display at a timing when the package 15 reaches the package conveyor 52. Accordingly, the operator can know a situation of the collection of the package 15 by simply viewing the operation state display panel 80.
  • switching from the vertical movement display to the rotation display can be performed according to time, for example. That is, the vertical movement display is started and counting is started after an instruction of the operator or after the operation of the package shutter 51, and the vertical movement display is switched to the rotation display at a timing when the count reaches a predetermined value.
  • switching from the vertical movement display to the rotation display is not limited to time.
  • the vertical movement display may be switched to the rotation display with, as a trigger, detection of the package 15 by a sensor or the like provided to the package conveyor 52 side.
  • the vertical movement display may be used to indicate an operation status of other devices, without limiting to the operation status of the package shutter 51.
  • the rotation display is performed using the three seven-segment displays, but the rotation display can be performed in a similar procedure even when one, two, or four or more seven-segment displays are used.
  • FIG. 8 is a view illustrating that on/off display is performed by lighting on/off each segment of the segment display section 81.
  • the seven-segment display can display some alphabets in addition to numbers.
  • the segment display section 81 of the present embodiment includes the three seven-segment displays arranged side by side in the lateral direction. Therefore, three alphabets can be displayed. As described above, as illustrated in FIG. 8 , the segment display section 81 can display "on" and "off".
  • the segment display section 81 When the on/off display is used, the segment display section 81 performs the "on" display when the target device (the doffing device 17, the package shutter 51, the package conveyor 52, the supply device 3, the bobbin conveyor 4, and the preparation device 8) is in operation. When the target device is not in operation, the segment display section 81 performs the "off" display.
  • the on/off display has high affinity with all devices.
  • the regular light-on and light-off patterns illustrated in FIGS. 6 to 8 described above are an example, and other patterns may be used to indicate the operation status of each device.
  • the segment display section 81 may display whether or not being in operation by lighting on or blinking a predetermined number or character.
  • the automatic winder 100 of the present embodiment includes the plurality of winding units 1a, the doffing device 17, the package conveyor 52, and the operation state display panel 80.
  • the winding unit 1a unwinds the yarn from the yarn supplying bobbin 12, and winds the unwound yarn to individually form the package 15.
  • the doffing device 17 doffs the package 15 formed by the winding unit 1a by removing the package 15.
  • the package conveyor 52 conveys the package 15 doffed by the doffing device 17.
