Definitions

  • the bobbin holding device receives the bobbin tube conveyed by the conveyor with the receiving section and directly holds the bobbin tube with the first holding section.
  • the bobbin holding device thus can directly hold the bobbin tube conveyed by the conveyor.
  • the supply device receives the bobbin tube held by the bobbin holding device and supplies the bobbin tube to the target position.
  • the bobbin setting device thus can supply the bobbin tube conveyed by the conveyor to the target position.
  • the yarn accumulating device 5 includes a yarn accumulating roller 51, a drive motor 52, and a yarn hooking member 53.
  • the drive motor 52 rotates the yarn accumulating roller 51.
  • the yarn hooking member 53 winds the yarn Y around the yarn accumulating roller 51.
  • the yarn accumulating device 5 winds the yarn Y around the yarn accumulating roller 51 to temporarily accumulate the yarn Y.
  • a first guide 11 is arranged in proximity to the upstream of the yarn accumulating device 5.
  • the first guide 11 guides the yarn Y to the yarn accumulating device 5.
  • a pair of second guide 12 and third guide 13 is arranged in proximity to the downstream of the yarn accumulating device 5.
  • the pair of second guide 12 and third guide 13 stabilizes the behavior of the yarn Y unwound from the yarn accumulating device 5.
  • the first guide 11 and the second guide 12 are movable to draw the yarn Y toward the yarn accumulating device 5 when performing a yarn joining operation, and the like.
  • the yarn joining section 91 is a splicer device adapted to carry out the yarn joining operation by twisting the yarn Y from the spinning device 3 and the yarn Y from the package P with the whirling airflow.
  • the yarn joining section 91 is not limited to the splicer device, and may be, for example, a mechanical knotter, and the like.
  • the bobbin preparing device 60 (not illustrated in FIG. 1 ) supplies a bobbin (bobbin tube) T around which the yarn is not wound.
  • the bobbin preparing device 60 is arranged at one end side of the machine in the direction in which the plurality of spinning units 1 are arranged side by side.
  • a plurality of bobbins T is stored in the bobbin preparing device 60.
  • the bobbin preparing device 60 is adapted to supply the bobbin tube to the belt conveyor 70 based on a command of the machine control device 140.
  • the bobbin preparing device 60 supplies the bobbin T while aligning the direction of the bobbin T to a predetermined direction.
  • the holding portions 114a and 114b are arranged to freely move in a direction of approaching to each other and a direction of separating from each other in the receiving section 112.
  • the holding portions 114a and 114b are supported by the receiving section 112 in a freely swinging manner, and may be configured to swing with a shaft on the basal end side as the center. According to such configuration as well, the pair of holding portions are arranged to freely move in the direction of approaching to each other and the direction of separating from each other.
  • the machine control device 140 When the bobbin T is gripped by the gripper 132, the machine control device 140 issues a command to the bobbin preparing device 60 to supply a new bobbin T to the belt conveyor 70. The machine control device 140 then issues a command to the bobbin holding device 110 to hold the bobbin T newly conveyed by the belt conveyor 70. The bobbin holding device 110 receives the new bobbin T and holds the bobbin T based on such command. The bobbin holding device 110 can transfer the holding bobbin T to the gripper 132 in the next doffing operation.
  • the bobbin holding device 110 of the spinning machine 10 of the present embodiment receives the bobbin T conveyed by the belt conveyor 70 with the receiving section 120 and directly holds the bobbin T with the bobbin holding section 114.
  • the bobbin holding device 110 thus can directly hold the bobbin T conveyed by the belt conveyor 70.
  • the bobbin holding device 110 moves the receiving section 112 and the bobbin holding section 114 together to the first position of receiving the bobbin T and the second position different from the first position by means of the arm section 118 and the drive section 120.
  • the bobbin holding section 114 is positioned in the internal space K of the hollow bobbin T to hold the bobbin T from the inner side of the bobbin T.
  • the bobbin T is, for example, formed to a tubular shape with paper. Therefore, if the bobbin T is gripped from the outer circumferential surface side, the bobbin T may be crushed.
  • the bobbin holding section 114 is thus positioned on the inner side of the bobbin T to hold the bobbin T.
  • the bobbin T has a strength with respect to the force applied from the inner side. Therefore, the bobbin holding section 114 can hold the bobbin T without crushing the bobbin T.
  • the configuration in which the bobbin holding device 110 receives the new bobbin T and sets the bobbin T in the cradle arm 41 in the doffing operation is described by way of example, but the reception of the new bobbin T by the doffing device 100 may be carried out when the doffing operation is not being carried out, that is, during standby.
