摘要： An object of the present invention is to provide a yarn slack eliminating device that enables tension applied to a yarn to be controlled while a spinning machine is in operation. A yarn slack eliminating device 12 includes an electric motor 25, a yarn slack eliminating roller 21, a yarn hooking member 22, an electromagnet 36, and a control section 74. The yarn slack eliminating roller 21 is rotationally driven by the electric motor 25. The yarn hooking member 22 is concentrically attached to the yarn slack eliminating roller 21 so as to be rotatable relative to the yarn slack eliminating roller 21. The electromagnet 36 generates a magnetic field to be applied to the yarn hooking member 22. The control section allows the magnetic field to generate a resistance torque resisting the rotation of the yarn hooking member 22 relative to the yarn slack eliminating roller 21. The control section 74 also controls an input to the electromagnet 36 to control the resistance torque (Fig. 3).

摘要： A spinning frame includes a yarn accumulating roller (21), an electric motor (25), and a unit controller (60). The yarn accumulating roller (21) temporarily accumulates a spun yarn produced by a spinning device (9) by winding the spun yarn around an outer peripheral surface thereof and rotating. The electric motor (25) drives and rotates the yarn accumulating roller (21). The unit controller (60) carries out a first control to control the electric motor (25) to rotate the yarn accumulating roller backward when it is necessary to unwind the spun yarn wound around the yarn accumulating roller. Next, the unit controller (60) carries out a second control to control the electric motor (25) to rotate the yarn accumulating roller (21) backward at a speed which is higher than a rotational speed during the first control. Then, the unit controller (60) carries out a control to spin off a yarn entangled with a flyer (38) or the like by temporarily increasing a backward rotational speed of the yarn accumulating roller (21) during the second control.

摘要： A yarn slack eliminating device includes a roller 42. A winding range 60 of the roller 42 around which a yarn is wound is formed in a taper shape in which a diameter decreases from an upstream side where the yarn starts to be wound around towards a downstream side. The winding range 60 includes a first taper section 62 and a second taper section 63, and a taper angle becomes moderate towards the downstream side in two stages at the first taper section 62 and the second taper section 63. An area of the first taper section 62 having a large taper angle is smaller than an area of the second taper section 63 having a small taper angle ( Fig. 4 ).

摘要： In order to control the speed of the rotor of a three-phase, synchronous motor of a sinusoidal type (M) driving a yarn-winding drum (R) for feeding a yarn (F) to a user machine (MF) under a desired tension, the motor is controlled instant-by-instant as a function of the instant position of the rotor (θrif), which is calculated by integrating a reference speed value (ωrif) and deriving from the latter an excitation angular parameter for the motor.

摘要： A spinning machine includes a yarn forming unit configured to form yarn from a spun material, a winding device configured to wind yarn formed by the yarn forming unit, a tension detecting unit configured to detect the tension of yarn in an upstream side from the winding device in a direction in which the yarn travels, and a control unit configured to control the yarn forming unit based on a result of detection by the tension detecting unit such that the yarn is wound onto the winding device with adjustment of the tension added to the spun material in the yarn forming unit. The control unit adjusts the tension by controlling a device of the yarn forming unit disposed at least in an upstream side or in a downstream side from a position at which the spun material is twisted in the direction in which the yarn travel.
