Therefore, as compared with the case described above, the length of the signal line can be shortened, and the space necessary for arranging the signal line can be reduced. Further, the main board 52 and the intermediate control board 53, the intermediate control board 53, the bobbin supply control board 54, and the unwinding auxiliary control board 55, which have no other board in between, are connected by signal lines 62b to 62d, respectively. Therefore, the arrangement of the signal lines can be simplified.

  In the winding unit 1, the main board 52, the intermediate control board 53, the bobbin supply control board 54, the unwinding auxiliary control board 55, the clearer board 56, the yarn splicing control board 57, the drum control board 58, the power board 51, It is necessary to supply power to the display control board 59.

  At this time, unlike the present embodiment, if the power supply board 51 and each board are directly connected to each other through the power supply lines, a long power supply line is required or the arrangement of the power supply lines becomes complicated. It may be necessary to secure an extra space for arranging the signal lines. In addition, extra space is required to arrange the power supply lines.

  Specifically, in the winding unit 1, an intermediate control board 53 is disposed between the power supply board 51, the bobbin supply control board 54, and the unwinding auxiliary control board 55, and the power supply board 51 and the display control are controlled. A main substrate 52 is disposed between the substrate 59. Furthermore, the power supply board 51, the main board 52, the intermediate control board 53, the yarn splicing control board 57, and the drum control board 58 are arranged at a relatively high density.

  Therefore, when the power supply board 51 and each board are directly connected by the power supply line, the power supply line for connecting the power supply board 51 and a board far away from the power supply board 51 and other boards are bypassed. As a result, the length of the power supply line is increased. In addition, a space for arranging power supply lines so as to bypass other substrates is also required. Furthermore, the arrangement of the power supply lines becomes complicated.

  On the other hand, in the present embodiment, the power supply board 51 is connected to the main board 52 and the drum control board 58 by the power supply lines 61a and 61f, respectively, and the main board 52, the intermediate control board 53, The yarn splicing control board 57, the drum control board 58, and the display control board 59 are connected by power lines 61b, 61e, and 61g, respectively, and further, the intermediate control board 53, the bobbin supply control board 54, and the unwinding assist control. The substrate 55 is connected by power supply lines 61c and 61d.

  As a result, power is directly supplied from the power supply board 51 to the main board 52 and the drum control board 58. The intermediate control board 53, the yarn splicing control board 57, and the display control board 59 are supplied with power from the power board 51 via the main board 52. Further, the bobbin supply control board 54 and the unwinding auxiliary control board 55 are supplied with power from the power board 51 via the main board 52 and the intermediate control board 53.

  Therefore, as compared with the case described above, the length of the power supply line can be shortened, and the space necessary for arranging the power supply line can be reduced. For a board far from the power supply board 51 or a board in which another board is disposed between the power board 51 and the board, the boards are connected to each other via a power line so that the power board 51 passes through the other board. Since power is supplied, the arrangement of the power supply lines can be simplified.

  Unlike the other boards, the power supply board 51 and the drum control board 58 are directly connected by the power supply line 62f without the main board 52, but this is because the power supply board 51, the main board 52, This is because the power line can be shortened as compared with the case where the main board 52 and the drum control board 58 are connected by the power line.

  Further, the power supply board 51, the main board 52, the intermediate control board 53, the bobbin supply control board 54, the unwinding auxiliary control board 55, the clearer board 56, the yarn splicing control board 57, the drum control board 58, and the display control board 59 are grounded. Since the ground is directly connected to the conductive machine base 7 and the support frame 12 without going through the wires, the ground wire becomes an obstacle when the power wires 61a to 61g and the signal wires 62b to 62g are arranged. The arrangement of the power supply lines 61a to 61g and the signal lines 62b to 62g becomes simpler.

  Further, since the connection between the boards by the power lines 61a to 61g and the signal lines 62b to 62g is performed by connecting the power lines 61a to 61g and the signal lines 62b to 62g to the connectors provided on each board, the power lines Connection between substrates by 61a-61g and signal lines 62b-62g can be performed easily.

  Next, modified examples in which various changes are made to the present embodiment will be described. However, the description of the same configuration as the present embodiment will be omitted as appropriate.
