Note that a period in which the basic operation in which the first free length FL1 is the basic length FL11 is performed as a period F1, and a period in which the first free length FL1 is changed temporarily to be larger than the basic length FL11 is a period F2. (See FIG. 6).
- a period for performing the basic operation is a period F1.
- the first free length FL1 is maintained at the basic length FL11.

- the first free length FL1 is temporarily expanded to FL12 longer than the basic length FL11.
- the turret 16 After expanding the first free length FL1 to FL12 longer than the basic length FL11, the turret 16 is rotated in the reverse direction to return the rotation angle of the turret 16 to the basic operation state. As a result, the first free length FL1 returns to the basic length FL11, and the changing operation ends.

That is, the yarn Y supplied to the spinning take-up device 100 arranged in the lower stage passes between the plurality of spinning take-up devices 100 arranged in the upper stage and is supplied from above to the traverse device 32. Is arranged.
- the spinning and winding apparatus 100 is configured so that the spinning and winding apparatus 100 is combined vertically in the upper and lower stages, and the yarn Y is supplied from above to the traverse apparatus 32 of each spinning and winding apparatus 100,
- the height of the spinning and winding equipment 200 increases, and the spinning and winding equipment 200 increases in size.
- workability for the spinning winding device 100 in the upper stage is deteriorated. For this reason, conventionally, it has been difficult to adopt a layout in which the spinning and winding device 100 is combined vertically in the upper and lower stages.
- the take-up device 100 constituting the take-up device 200 of the present embodiment has a small size in the longitudinal direction and is compact as described in the first embodiment, a plurality of the take-up devices are provided. Even if 100 are stacked in a vertical direction in multiple stages, the height of the spinning and winding equipment 200 can be reduced. In particular, the workability with respect to the upper stage yarn winding device 100 is improved. For this reason, a layout in which a plurality of the yarn winding devices 100 are stacked in a vertical arrangement in the vertical direction can be made without sacrificing workability, and space can be used effectively.
- the spinning and winding equipment 300 of this embodiment is configured by combining a plurality of spinning and winding devices 100 described in Embodiment 1 in an upper stage and a lower stage. Detailed description of the spinning and winding device 100 will be omitted.
- the take-up winding equipment 300 of the present embodiment has the take-up device 100 installed in a horizontal orientation in both the upper and lower stages.
- the yarn Y is spun by an upper spinning device (not shown), and is sent to each spinning winding device 100 via rollers 52, 54, 56 and the like.
- the traveling direction of the yarn Y is changed by the roller 56 and is supplied from the side to the traverse device 32 of each spinning winding device 100.
- the spinning and winding apparatus 100 is configured so that the spinning and winding apparatus 100 is combined horizontally in the upper stage and the lower stage, the yarn Y is supplied from the side to the traverse apparatus 32 of each spinning and winding apparatus 100.
- the width of the take-up winding device 300 is widened and the size of the take-up winding device 300 is increased in the horizontal direction.
- the horizontal width of the spinning and winding equipment 300 is widened, a work space required between the adjacent spinning and winding equipment 300 is reduced, and workability for the spinning and winding apparatus 100 is deteriorated.
- the take-up device 100 constituting the take-up device 300 has a small size in the vertical direction and is compact. Even if 100 are stacked in multiple stages in the horizontal direction, the horizontal width of the spinning and winding equipment 300 can be reduced. For this reason, a required working space can be secured between the adjacent spinning and winding equipment 300, and workability for the spinning and winding apparatus 100 can be improved. For this reason, a layout in which a plurality of the spinning and winding apparatuses 100 are stacked in a horizontal manner in the vertical direction without sacrificing workability becomes possible, and space can be used effectively.
- the spinning and winding device of the present invention is industrially useful because the size in the longitudinal direction can be kept small.
- the spinning and winding equipment constituted by combining a plurality of the winding and winding devices of the present invention enables a layout in which a plurality of spinning and winding devices are stacked in a vertical direction without sacrificing workability, and space is effectively used. Therefore, it is useful industrially.
