DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a special composite false twist device.

[0002]

2. Description of the Related Art Conventionally, a composite false twisting device has a second feed roller or a third feed roller for feeding an effect yarn, also called a flower yarn or a sheath yarn, to a twisting region of a core yarn in addition to a normal false twist crimping device. Rollers are provided. The length, size, and formation position of a wound structure such as a slab or a nep formed by winding on a core yarn are fixed by an effect yarn supply guide position set at the start of processing. For this reason, the effect yarn supply guide position is changed during the composite false twisting by changing the distance from the core yarn or moving the yarn in the normal or reverse direction to the running direction of the core yarn so as to impart randomness to the wound structure. Devices have also been proposed. However, in such an apparatus, since the change is only on the effect yarn supply side, there is a limit to the randomness.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to arbitrarily or irregularly change the length, size and formation position of a wound structure such as a slab or a nep during composite false twisting. It is an object of the present invention to provide a composite false twisting device that can be used.

[0004]

According to the present invention, a heater and a false twist spindle are arranged between a core yarn supplying device and a take-up roller, and an effect yarn guide is arranged between the core yarn supplying device and the heater. In a composite false twisting device in which the effect yarn supplied from the effect yarn supply roller via the effect yarn guide is wound around the core yarn, the effect yarn guide can reciprocate in parallel with the core yarn traveling path in the core yarn twisting area. , A guide position control mechanism that controls the distance and speed of movement of the guide by a pulse signal,
The special composite false twisting device is provided with an effect yarn supply control mechanism for controlling the supply amount of the effect yarn based on the guide position output signal and a spindle control mechanism for controlling the rotation speed of the false twist spindle.

The apparatus of the present invention will be described with reference to the drawings.
Is an explanatory view of the apparatus of the present invention, wherein a heater (3) is provided between a take-up roller (5) and a take-up roller (5) and a take-up roller (5) such as a nip roller or a magnet tensor for supplying the take-up area to the take-up area. ) And a false twist spindle (4) are sequentially arranged, an effect yarn guide (8) is arranged in a core yarn twisting area between the core yarn supply device (1) and the heater (3), and an effect yarn supply roller ( 7) A composite false twist device having a mechanism in which an effect yarn (6) supplied from 7) via an effect yarn guide (8) is wound around a core yarn (1), wherein the effect yarn guide (8) is It is arranged so as to be movable in the forward and reverse directions parallel to the yarn running direction.

The effect thread guide (8) is a guide fixture (1) that can linearly reciprocate by a servomotor (9).
0). The rotation speed of the servo motor (9) is controlled by the number of pulses of the pulse train of the pulse signal generated by the pulse generator of the guide position control device (11) of the guide position control mechanism, and the rotation speed is controlled by the pulse frequency. The rotation angle corresponds to the moving distance of the guide (8), and the rotation speed corresponds to the moving speed of the guide (8). The moving speed of the guide (8) is set to a constant speed or a variable speed from a speed lower than the running speed of the core yarn to a speed higher than the running speed of the core yarn. Accordingly, the effect yarn is such that the overfeed state at the time of the supply and the starting point of the winding can vary extremely, and the effect yarn (6) is wound around the core yarn by the moving distance and speed of the guide (8). The state can be changed.

[0007] The effect yarn supply roller (7) and the false twist spindle (4) are driven so that their rotation speeds can be varied by drive motors (12) and (13) such as independent servo motors. The effect yarn supply roller (7) is configured such that the guide position control device (11) controls the number of rotations of the drive motor (12) by a guide position output signal generated at least at a start point and an end point of movement of the guide (8). The supply amount of the effect yarn is controlled. Therefore, the effect yarn can change the winding state around the core yarn due to the fluctuation of the overfeed state at the time of the supply. The rotation speed of the false twist spindle (4) is controlled by controlling the rotation speed of the drive motor (13) by the guide position output signal generated by the guide position control device (11). . Accordingly, the core yarn also changes the winding state of the effect yarn due to the change of the twist state in the false twist spindle.

The movement of the effect yarn guide position, the control of the effect yarn supply amount and the rotation of the false twist spindle in the apparatus of the present invention are performed by a guide position control device, and a guide position output set in advance in accordance with the effect yarn guide movement is provided. A signal is received as a shift signal of each drive motor, and the effect yarn supply amount and the false twist spindle rotation are controlled by a command set according to the shift signal.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In an embodiment of the apparatus according to the present invention, the running speed of the core yarn is 40 m / min, the number of rotations of the false twist spindle is the number of false twists, and the effect yarn guide is positioned from the upstream position to the downstream position of the twisting area. 1250 T / M during the movement from the downstream position to the upstream position, 3000 T / M during the movement from the downstream position to the upstream position, and the overfeed rate 125 during the movement of the effect yarn guide from the upstream position to the downstream position of the twisting area. %, While moving from the downstream position to the upstream position, the overfeed rate is 25%,
Assuming that the effect yarn guide distance from the core yarn is 200 mm, the effect yarn guide is moved at a speed of 30 m / min in the same direction as the core yarn traveling direction from the upstream position of the twisting area having a core yarn length of 500 mm,
At the intermediate position, the speed was changed to 60 m / min to move, and the operation of moving from the downstream position to the original upstream position at 8 m / min was programmed. Polyester fiber 75d /
36f, triacetate fiber 55d / 15 as effect yarn
When composite false twisting was performed under the above-described program conditions using f, a composite false twist yarn having a triple, five-fold, and seven-fold wound structure mixed was obtained.

According to the use of the apparatus of the present invention, the distance and speed of the movement of the effect yarn guide, the supply amount of the effect yarn, and the number of revolutions of the false twist spindle can be set in advance in the guide position control mechanism by any combination. If it is programmed to emit as a pulse signal and a guide position output signal, the effect yarn travels from the effect yarn supply roller whose rotation speed can be varied in parallel with the core yarn traveling path in the core yarn twisting area. The yarn is supplied via an effect yarn guide movably arranged at a speed before and after the rotation, and the core yarn is twisted by a false twist spindle whose rotation speed can be varied, and triple to sevenfold winding of the effect yarn on the core yarn is performed. A very large number of combinations are possible, such as the formation of a round structure, and various types of slabs and neps from regular slabs and neps to extremely random slabs and neps in a single device or in a single composite false twisted yarn. Various winding structures It can form.
