False-twisting machine and fiber waste collection device

Abstract

[Problem to be Solved] Provided is a false-twisting machine and fiber waste collection device configured to separate fiber waste from air appropriately thereby capable of suppressing the discharge of the fiber waste to an exterior thereof. [Solution to Problem] In a false-twisting machine, a fiber waste collection device 1 configured to collect fiber waste includes: a fiber waste transfer pipe 11 arranged with a plurality of suction units 15 for suctioning fiber waste such that the fiber waste suctioned from the plurality of suction units is transferred along with air through the fiber waste transfer pipe; a fiber waste collection unit 13 for collecting therein the fiber waste transferred through the fiber waste transfer pipe; a cyclone separator 30 arranged between the fiber waste transfer pipe and the fiber waste collection unit configured to separate the fiber waste from the air transferred through the fiber waste transfer pipe so as to collect the separated fiber waste in the fiber waste collection unit; and an air discharge unit 50 connected to the cyclone separator for discharging the air obtained after having been separated from the fiber waste. The fiber waste includes a polyester fiber or a polyamide fiber. The cyclone separator includes a body portion 32 in a tubular shape connected with the fiber waste transfer pipe such that a longitudinal direction of the fiber waste transfer pipe follows an inner peripheral wall of the body portion, the body portion being configured to cause the fiber waste transferred through the fiber waste transfer pipe to travel downward along the inner peripheral wall due to a centrifugal force; a fiber waste transfer portion 42 connected to a lower portion of the body portion; and a fiber waste discharge unit 46 for discharging the fiber waste separated from the air to the fiber waste collection unit. The fiber waste transfer portion has an inclined portion 44 whose diameter decreases from a point of connection with the body portion toward the fiber waste discharge unit. The inclined portion is formed in a tapered shape having an angle formed with respect to a vertical direction within a range of larger than or equal to 7° and smaller than or equal to 10°.
