Definitions

• the spun yarn take-up machine 1 includes a first godet roller 11, a second godet roller 12, and a yarn winding apparatus 13 (yarn winding apparatus of the present invention).
• the endless belt 34 is wound onto the driving pulley 32 and the two driven pulleys 33.
• the traverse guide 22 is attached to a substantially linear portion of the endless belt 34, which is located between the two driven pulleys 33.
• the traverse motor 31 rotationally drives the driving pulley 32
• the endless belt 34 is driven and the traverse guide 22 is reciprocated in the front-rear direction (the axial direction of bobbin B).
• the traverse guide 22 is able to move to a position substantially identical with that of the slit S in the front-rear direction. As the yarn Y is moved to the substantially same position as the slit S in the front-rear direction by the traverse guide 22, it is possible to allow the slit S to catch the yarn Y and to thread the yarn Y to the bobbin B.
• the structure of the traverse device 30 is not limited to the above-described one.
• a single traverse motor (not illustrated) that simultaneously drives the driving pulleys 32 may be provided as a driving source.
• the turret 23 is a disc-shaped member.
• the turret 23 is rotatably supported by the frame 20.
• the position of the rotation shaft of the turret 23 coincides with the center position of the turret 23.
• the rotational shaft of the turret 23 extends along the front-rear direction.
• the turret 23 is rotationally driven by a turret motor 101 (see FIG. 5 ).
• the two bobbin holders 24 are both long in the front-rear direction.
• the two bobbin holders 24 are rotatably supported at their rear end portions.
• the two bobbin holders 24 are provided to be point symmetric about the rotation axis center C of the turret 23 (see FIG. 2 ).
• the axial direction of each bobbin holder 24 is substantially in parallel to the front-rear direction (see FIG. 1 ).
• bobbins B are attached to be lined up in the front-rear direction.
• Each bobbin B is attached to the bobbin holder 24 so that the axis of the bobbin B is in parallel to the front-rear direction.
• each bobbin holder 24 for example, six bobbins B are attached to each bobbin holder 24. It is noted that the number of bobbins B attachable to the bobbin holder 24 not limited to this number.
• Each of the two bobbin holders 24 is rotationally driven by an individual winding motor 102 (see FIG. 5 ).
• one of the following states is established: a state in which the bobbins B attached to one bobbin holder 24 among the two bobbin holders 24 are at winding positions whereas the bobbins B attached to the other bobbin holder 24 are at standby positions; and a state in which the bobbins B attached to the one bobbin holder 24 are at the standby positions whereas the bobbins B attached to the other bobbin holder 24 are at the winding positions.
• the winding position is in the vicinity of the later-described contact roller 25.
• multiple bobbins B1 attached to a bobbin holder 24A among two bobbin holders 24A and 24B are at the winding positions, whereas multiple bobbins B2 attached to the bobbin holder 24B are at the standby positions.
• the bobbin holder 24A is positioned above the bobbin holder 24B.
• the bobbin holder 24 in which the attached bobbins B are located at the winding positions may be referred to as the upper bobbin holder 24.
• the yarns Y sent from the second godet roller 12 to the yarn winding apparatus 13 are simultaneously wound onto the bobbins B at the winding positions.
• the contact roller 25 is provided immediately above the upper bobbin holder 24.
• the axial direction of the contact roller 25 is substantially in parallel to the front-rear direction.
• the contact roller 25 is configured to make contact with the surfaces of the packages P supported by the upper bobbin holder 24. With this, the contact roller 25 applies a contact pressure to the surface of each package P to adjust the shape of each package P.
• the controller 26 includes, e.g., a CPU, a ROM, and a RAM which are not illustrated. As shown in FIG. 5 , the controller 26 is electrically connected to each component of the yarn winding apparatus 13 (see, e.g., the traverse motor 31, the turret motor 101, and the winding motor 102 described above). The controller 26 is configured to be able to control the operation of each component of the yarn winding apparatus 13.
• the yarn winding apparatus 13 structured as described above, when the upper bobbin holder 24 is rotationally driven, the yarns Y traversed by the traverse guides 22 are wound onto the bobbins B at the winding positions, with the result that the packages P are formed.
• the turret 23 is rotated to switch the upper and lower positions of the two bobbin holders 24 so that the empty bobbins B become at the winding positions. Then the yarn threading to the empty bobbins B is performed and the formation of packages P starts again.
• the bobbin holder 24 to which the fully-formed packages P are attached is moved to the lower position.
• FIG. 6 is a front view showing the bobbins B1 and B2 attached to the respective bobbin holders 24 and their surroundings.
• FIG. 7 shows the bobbins B1 and B2 attached to the respective bobbin holders 24 and their surroundings.

• the yarn winding apparatus 13 further includes a separator 27 and regulatory guides 28.
• the separator 27 is configured to temporarily hold and move the yarns Y at the time of the switching operation. As shown in FIG. 6 , the separator 27 includes a rotation shaft 41, a supporting member 42, and a yarn holding member 43.
• the rotation shaft 41 extends in the front-rear direction (direction perpendicular to the plane of FIG. 6 ).
• the rotation shaft 41 supports the support member 42 to be rotatable.
• the supporting member 42 is, for example, a substantially plate-shaped member extending in the front-rear direction.
• the supporting member 42 is driven and moved between a standby position (see two-dot chain lines in FIG. 6 ) and a yarn holding position (see full lines in FIG. 6 ) by a rotational drive unit 103 (see FIG. 5 ).
• the standby position is a position that does not overlap the turret 23 when viewed in the front-rear direction, for example.
• the yarn holding position is a position of the supporting member 42, where the yarns Y are held by the yarn holding member 43.
• the rotational drive unit 103 may include, for example, an unillustrated motor as a driving source.
