  • the spinning machine 100 can change the additive amount of the cleanser in accordance with the characteristic of the sliver F. That is, when producing the spun yarn Y from the sliver F added with the oiling agent, the spinning machine 100 can add an appropriate amount of the cleanser to the air to be supplied to the pneumatic spinning devices 6 in accordance with the characteristic of the sliver F. Accordingly, the oiling agent applied to the sliver F is prevented from being adhered to the spinning chamber 65 and from being accumulated therein, and manufacturing quality and productivity of the spinning machine 100 can be improved. Furthermore, the spinning machine 100 can produce the spun yarn Y from various types of slivers F.
  • Such a structure can be accomplished by the control device C monitoring operational status of each of the spinning units 1.
  • a spinning control section C2 of the control device C can receive a yarn travelling signal from the yarn defect detecting and removing device 8 of each of the spinning units 1.
  • the spinning control section C2 controls the air compressing device 32 to add the cleanser.
  • the spinning control section C2 determines that none of the spinning units 1 is producing the spun yarn Y. Then, the spinning control section C2 controls the air compressing device 32 not to add the cleanser.
  • the spinning machine 100 when at least one of the spinning units 1 is producing the spun yarn Y, the spinning machine 100 can supply the air added with the cleanser to the pneumatic spinning devices 6 in the spinning units 1. Accordingly, the oiling agent applied to the sliver F is prevented from being adhered to the spinning chamber 65 and from being accumulated therein, and manufacturing quality and productivity of the spinning machine 100 can be improved.
  • the cleanser supplying device 3 stops adding the cleanser to the air. Consequently, cleanser consumption in the spinning machine 100 can be reduced, and manufacturing costs of the spun yarn Y can be reduced.
  • the spinning machine 100 stops driving of the compressed air feeding device 21 in addition to stopping the addition of the cleanser. Accordingly, the spinning machine 100 can further reduce manufacturing costs of the spun yarn Y.
  • Such a structure is accomplished by having the accumulated amount of the cleanser in the cleanser tank 33 monitored by the control device C.
  • the spinning control section C2 receives a detection signal from the level sensor 331 provided at the cleanser tank 33 and monitors the accumulated amount of the cleanser.
  • the spinning control section C2 controls all the spinning units 1 to stop producing the spun yarn Y.
  • the spinning control section C2 stops driving sources of the draft device 5, the yarn feeding device 7, and the winding device 9 or the like in the spinning units 1.
  • the spinning control section C2 controls the air compressing device 32 to stop adding the cleanser.
  • the sliver F is fed from top to bottom.
  • a can storing the sliver F may be arranged in a lower portion of the spinning machine 100 and the winding device 9 may be arranged in an upper portion of the spinning machine 100.
