Definitions

  • the present invention relates to a textile machinery.
  • the operation executing cart for executing the operation is selected from the plurality of the operation carts capable of executing the operation with respect to the operation requesting unit in accordance with an occurrence of the operation request from the operation requesting unit to which only one of the operation carts can execute the operation. Accordingly, the operation executing cart corresponding to processing ability with respect to the operation request is selected, and the operation executing cart selected according to the processing ability can execute operation with respect to the operation requesting unit that can receive the operation from the plurality of the operation carts.
  • the textile machinery according to the present invention can efficiently control the operation cart that executes the operation.
  • the control section is adapted to select one operation cart having a largest number of occurrences of the operation requests within the exclusive region from the plurality of the operation carts that can execute the operation with respect to the operation requesting unit and to control the selected operation cart to execute the operation only with respect to the operation requesting units located within the exclusive region. Accordingly, the operation cart adapted to execute the operation can be efficiently controlled without the execution of the operation concentrating on the operation cart having a large number of occurrences of the operation requests.
  • the control section is preferably adapted to select the operation executing cart for executing the operation in accordance with a distance from the operation requesting unit located within the overlapping region to the relevant operation carts. For example, if an operation request is made from the operation requesting unit that can receive the operation from the plurality of the operation carts, the operation can be executed by the operation cart of which a distance to the relevant operation requesting unit is short, and hence the operation executing cart can be rapidly moved to the operation requesting unit that made the operation request.
  • the processing unit preferably includes an identifying means for identifying the operation executing cart that has executed the operation. Accordingly, the operation cart that executed the operation can be identified by the processing unit.
  • the defining means is preferably a range-end sensor provided at least at one end of range ends of the travelling path.
  • the travelling path of the operation cart can be defined by the range-end sensor provided at least at one end of the range ends of the travelling path.
  • the textile machinery further includes a track rail adapted to guide the plurality of the operation carts to travel along the travelling path.
  • the range-end sensors adapted to define the travelling path of adjacent operation carts one of the range-end sensors is preferably provided on a first surface extending in a direction substantially parallel to a direction in which the track rail extends, and another one of the range-end sensors is preferably provided on a second surface which is a surface different from the first surface and which extends in the direction substantially parallel to the direction in which the track rail extends. If the travelling paths defined by the range-end sensors overlap, the range-end sensor adapted to define one travelling path and the range-end sensor adapted to define the other travelling path are respectively provided on different surfaces of the track rail. By providing the range-end sensors at different positions, a false detection of the range ends can be prevented and the travelling path can be reliably defined by the range-end sensors.
  • each spinning unit 2 includes a draft device 7, a pneumatic spinning device 9, a yarn accumulating device 12, a waxing device 14, and a winding device 13 arranged in this order from upstream to downstream.
  • the draft device 7 is arranged in proximity to an upper end of a housing 6 of the spinning machine 1.
  • a fiber bundle 8 fed from the draft device 7 is spun by the pneumatic spinning device 9.
  • a spun yarn 10 fed from the pneumatic spinning device 9 is passed through a yarn clearer 52, fed further downstream by the yarn accumulating device 12, and applied with wax in the waxing device 14. Thereafter, the spun yarn 10 is wound by the winding device 13, and a package 45 is formed.
  • a process of winding the spun yarn 10 into the package 45 is an example of yarn processing.
  • the yarn accumulating device 12 is arranged downstream of the pneumatic spinning device 9.

  • the yarn accumulated amount detecting sensor 27 detects, in a non-contacting manner, an accumulated amount of the spun yarn 10 accumulated on the yarn accumulating roller 21, and transmits the accumulated amount to a control device 53 (see FIG. 4 ).
  • the upstream guide 23 is arranged slightly upstream of the yarn accumulating roller 21.
  • the upstream guide 23 appropriately guides the spun yarn 10 with respect to the outer peripheral surface of the yarn accumulating roller 21.
  • the upstream guide 23 prevents the twist of the spun yarn 10 propagating from the pneumatic spinning device 9 from being transmitted downstream of the upstream guide 23.

  • the spun yarn 10 spun by the pneumatic spinning device 9 is passed through the yarn clearer 52 before being wound by the yarn accumulating device 12.
  • the yarn clearer 52 monitors the thickness of the travelling spun yarn 10, and when a yarn defect of the spun yarn 10 is detected, the yarn clearer 52 transmits a yarn defect detection signal to the control device 53.
  • the control device 53 Upon receiving the yarn defect detection signal, the control device 53 immediately stops ejection of compressed air from the whirling airflow generating nozzle of the pneumatic spinning device 9. The whirling airflow is then stopped, the twisting of the fiber bundle 8 is stopped, and introduction of the fiber bundle 8 to the pneumatic spinning device 9 is also stopped. A continuation of the fibers is disconnected in the pneumatic spinning device 9, and the spun yarn 10 is cut. Thereafter, the control device 53 further stops the draft device 7 and the like. The control device 53 transmits a control signal to the yarn joining cart 3, and the yarn joining cart 3 travels to the front of the spinning unit 2. Thereafter, the pneumatic spinning device 9 and the like are driven again, the yarn joining cart 3 performs the yarn joining operation, and winding is resumed.
