Embodiment Construction

[0009] Below, according to figure 1 , an embodiment of the present invention will be described.

[0010] Such as figure 1 As shown, the ring spinning machine 10 includes a 3-wire draft device 11 including a front roll 11a, an intermediate roll 11b, and a rear roll 11c. The roving S1 that is a fiber bundle is supplied to the rear roller 11c from a roving roll suspended from a creel (not shown). The roving S1 supplied to the rear roller 11c is drafted by the rear roller 11c, the intermediate roller 11b, and the front roller 11a to become a carded yarn, and the carded yarn becomes a spun yarn and passes through a snail wire (not shown). ) and a traveling automatic splicer and is wound on the bobbin 12a provided for each spindle 12.

[0011] In the ring spinning machine 10 , a yarn breakage sensor 13 is provided for each spindle 12 . In the ring spinning machine 10, a plurality of spindles 12 are simultaneously spun, and even if yarn breakage occurs during spinning, the spindl...

Abstract

The invention relates to a control method of a spinning machine provided with a pneumatic clearing device and the spinning machine. The control method comprises steps that broken ends are detected by using a broken end sensor disposed on each spindle; in order to respond to the broken end detection, fiber beam supply stopping device used to stop the supply of a stretching device with the fiber beams is activated to work by cutting off fibers provided to the spindle generating the broken ends, and in addition, the downstream part of the flowing direction of the fiber beam cut off by the fiber beam supply and disposed above the fiber beam supply stopping device is a downstream side fiber beam; in order to respond to the broken end detection, the downstream side fiber beam is used to attract increased attraction force of a removed attraction part. When at least a part of the downstream side fiber beam is attracted by the attraction part, the attraction force of the attraction part is reduced.

Description

technical field [0001] The present invention relates to a control method of a spinning frame equipped with a pneumatic clearer and the spinning frame. Background technique [0002] In the spinning frame, if a broken end occurs during spinning, the roving or sliver (hereafter, they are collectively referred to as a fiber bundle) may be wound on the front roller of the drafting device or the like and used for the subsequent piecing work. bring hindrance. Therefore, the spinning frame is equipped with a pneumatic yarn clearing device that sucks and removes the fiber bundle of the broken spindle by air (for example, refer to JP-A-57-154423). The pneumatic yarn clearing device includes a pneumatic duct extending in the longitudinal direction of the spinning frame. A suction nozzle (suction portion) extending toward the front roller is provided in the air duct. In the pneumatic pipeline, negative pressure is applied by a negative pressure source. In the pneumatic yarn clearing...
