DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a full bobbin in which two bobbin holders are arranged at symmetric positions on concentric circles of a turret board, and are held by the bobbin holder by rotation of the turret board. The present invention relates to a turret type winding device for continuously winding yarn by alternately changing the position of a bobbin and an empty bobbin.

(Prior Art) In a conventional turret type winding device, slack of a yarn at the time of winding is removed by adjusting the number of rotations of a spindle to the speed of a yarn supplied at a constant speed. The peripheral speed of the full bobbin is much faster than the peripheral speed of the empty bobbin due to the diameter of the bobbin. From the moment the picked-up yarn is wound around the outer periphery of the empty bobbin, the supply yarn is greatly slackened due to the delay of the peripheral speed of the empty bobbin. This becomes more remarkable as the diameter ratio with the wound bobbin is larger.

For this reason, the present inventor drives each spindle of a pair of bobbin holders disposed on a turret board by a single prime mover via a clutch mechanism capable of switching transmission power in a stepwise manner. Is controlled by a cam mechanism in accordance with the rotation of the turret board, and the rotating torque applied to the full bobbin at the time of the yarn switching operation is reduced to a winding torque necessary for obtaining a normal winding tension, and the peripheral speed of the empty bobbin is reduced. A turret type winding device has been proposed in which the circumferential speed of the full bobbin is set higher to remove slack of the yarn before winding on the empty bobbin. (Japanese Patent Application No. 1-249192) (Problem to be Solved by the Invention) In the winding device proposed above, the newly set empty bobbin is orbitally moved to the winding start position while being accelerated, and is fully loaded on the spot. In order to change the bobbin from the bobbin to the empty bobbin, the fully-wound bobbin located in a symmetrical relationship with the bobbin has its clutch mechanism rotated in a half-clutch state with a torque equal to or less than the normal winding torque and after the yarn switching, so At the time of switching, the cut end of the wound yarn is swung and hits the outer surface of the bobbin immediately after the start of winding, and the yarn end may be drawn into the wound yarn and wound around the bobbin. In order to prevent such adverse effects, the full bobbin is stopped by operating the clutch mechanism of the spindle from the outside by an electromagnetic solenoid or a fluid cylinder mechanism, or a cutting thread of the full bobbin by interposing a partition plate between both bobbins. Although it is conceivable to prevent the harmful effects of the ends, there have been problems in that the means for preventing the harm are complicated and the equipment cost is greatly increased.

(Means for Solving the Problems) The present invention eliminates the above-mentioned conventional inconveniences, and rapidly stops the rotation of the full bobbin immediately after the yarn switching to eliminate the swinging of the cut yarn end at the end of the winding, so that the empty bobbin is eliminated. It is intended to provide a device intended to prevent illegal winding of the yarn around
A pair of bobbin holders are arranged so that their axes are parallel to each other, and they are arranged at symmetrical positions on the same circumference, sandwiching the center of the turret plate, and revolve. In a turret type winding device in which a single prime mover drives the motor to rotate and the transmission torque of each clutch is switched by a cam mechanism that follows the revolution of the turret board, the switching cam mechanism of each clutch finishes doffing. In the section from the appropriate position after the position to the yarn switching position immediately before the winding start position to the position including the full winding position through the winding start position, the clutch is fully operated, and the yarn switching position is passed through the full winding position. The section up to the position including the symmetrical thread switching position is smaller than the torque required to maintain the normal winding tension, and after passing through the thread switching symmetric position, A section from the doffing start position symmetrical to the position to at least the doffing end position symmetrical to the full winding position is configured to be inoperative, and a brake mechanism for stopping the spindle during the inoperative section of the clutch is further provided. When the yarn is switched from the full bobbin to the empty bobbin at the yarn switching position, the empty bobbin moves from the yarn switching position to the winding start position, and the full bobbin moves from the switching symmetry position to the doffing start position. The turret board is continuously revolved so as to move quickly.

(Operation) As shown in FIG. 1 of the embodiment, the turret-type winding device of the present invention uses a traverse device (4) to feed a supply yarn Y sent at a constant speed at a winding start position A. While being traversed by the swinging guide (5), it is wound on the bobbin (3a) on the bobbin holder (1a) which rotates at the winding start position A, and this is in a winding state, from the full winding position B to a further winding start position. When passing the doffing start position D symmetrical to A, the full bobbin (1a) is replaced with a new empty bobbin, and the new bobbin passes through the doffing end position E symmetrical to the full winding position B to the winding start position A. It revolves toward, but a thread switching position F is provided immediately before the winding start position A,
Therefore, a line switching symmetric position C is formed immediately before the doffing start position D symmetrically with the line switching position F. As described above, one of the bobbin holders (1a) has a winding start position A → a full winding position B → a yarn switching symmetric position C → a doffing start position D → a doffing end position E → a yarn switching position F → a winding start position A. Is repeated as one revolution,
The bobbin holder (1b) symmetrical to the bobbin holder (1a) has a doffing start position D → doffing end position E → thread switching position F → winding start position A → full winding position B → thread switching symmetric position C
→ The doffing start position D is set to one revolution and repeated, so that the predetermined operation is performed in each section, and both bobbin holders (1
a) The clutches (42) in (1b) are brought into a completely coupled state from an appropriate position in a section from the doffing end position E to the yarn switching position F to at least a position beyond the full winding position B, and the spindle is accelerated and rotated. From the position after the full winding position B to a position slightly beyond the yarn switching symmetric position C, the yarn is rotated in a half-clutch state with a torque smaller than the torque required to maintain the normal winding tension. At least a section from the position slightly beyond C to the doffing end position E via the doffing start position D and at least the doffing end position E, and during the inoperative section, the brake mechanism (67) is acted on the spindle to operate the spindle. The rotation was stopped.

The stepwise switching operation of the clutch (42) between the fully engaged state, the half-clutched state, and the inoperative state is performed by a circle provided on the outside of the turret along the revolving locus of the spindles of both bobbins as illustrated in FIG. This is performed by a cam mechanism including an arcuate cam (54) and a cam follower (61) which abuts against the cam. Thus, the bobbin (3a) which is full at full position B
However, when the clutch (42) is in a half-clutch state and reaches the thread switching symmetric position C when the full winding position B is exceeded,
In contrast to this, the other empty bobbin (3b) is at the doffing end position E
After passing through, the yarn is accelerated by the complete engagement of the clutch (42) to reach the yarn switching position F, and the yarn is switched without causing slack in the yarn due to the rotation speed difference between both bobbins with the full bobbin (3a). The yarn between the bobbins is also cut under a predetermined tension to complete the yarn switching operation. During this time, both bobbins (1a)
(1b) Empty bobbin (3b) due to continuous revolution of turret board
Quickly moves to winding start position A, and the full bobbin (3
a) quickly moves to the doffing start position D, but the clutch (42) of the full bobbin (3a) becomes inoperative when passing the thread switching symmetric position C by the cam mechanism, and Since the spindle is stopped by the mechanism (67), the cut yarn end of the winding yarn of the full bobbin (3a) is prevented from swinging, and the empty bobbin (3b) close to the full bobbin (3a) is taken up. It is possible to prevent the yarn end of the full bobbin (3a) from being accidentally wound by the yarn.

When the empty bobbin (3b) reaches the yarn switching position F in order to perform the above-mentioned yarn switching operation properly, both bobbins (3a)
When the revolution of (3b) is temporarily stopped, the continuous revolution is performed again when the thread switching operation is completed, and the empty bobbin (3
b) is a bobbin (3a) which is quickly moved to a winding start position A, and a full bobbin (3a) is rapidly moved to a doffing start position D, so that the next operation is rapidly advanced. The empty bobbin (3b) faces the full bobbin position B while winding, and the full bobbin (3a) turns to the empty bobbin at the doffing start position D in a state where the clutch (42) is in an inoperative state and the sunpindle is braked. After the exchange, the new empty bobbin passes the doffing end position E,
The brake of the spindle is released, the clutch (42) is accelerated and rotated by complete coupling, and is revolved toward the yarn switching start position F, so that the above-described winding operation associated with the rotation of the turret disk is continuously performed.

At this time, the clutch (42) of the bobbin holder (1b) holding the empty bobbin (3b) is fully operated by the action of the cam mechanisms (53) and (54) during the revolution, and
Since the clutch (42) on the other full bobbin (3a) side is in a half-clutch state and slips, and the rotational torque is smaller than the torque required to maintain the normal winding tension, the empty bobbin (3b) Rotates faster than the yarn supply speed.
The reason why the empty bobbin (3b) accelerates is as follows.

When a variable speed motor is used as the drive motor (23) for rotation of the spindles (11), the rotation of the motor is controlled by a dancer arm provided in the yarn Y supply path so that the winding tension is constant. Control the number and therefore the full bobbin (3
When the transmission torque of the clutch (42) in a) is reduced by the abutting operation of the cam follower (53) against the plate cam (54) as described above, the dancer arm is displaced to the speed increasing side, and the rotational speed of the variable speed motor is increased. To accelerate the empty bobbin (3b).
When a torque motor is used as the drive motor (23), the torque characteristics are determined. If the load decreases, the rotation speed increases in reverse, so that the full bobbin (3a) is in a half-clutch state and When the load on the motor is reduced by reducing the power transmission to the motor, the speed of the motor increases and the rotation of the other empty bobbin (3b) is accelerated.

As described above, the thread guide (5) folded back from the leading end of the empty bobbin (3b) traverses to the thread holding section (38) outside the base end of the empty bobbin (3b) exceeding the normal twill amplitude to supply the supply yarn Y. The supply yarn Y entrained by the yarn holding portion (38) falls into the gap between the annular gripping member (33) and the friction member (36), and the yarn guide (5) is folded back on the holder base end side. When the direction is changed, the limit switch (66) acts to reverse the operation of the air cylinder (43), and the traverse cam (4a) returns to the normal traverse operation position. The gripping member (33) is pushed back by the elastic force of the compression spring (37), and is reliably sandwiched between the friction member (36) and the gripping member (33). Thus, the winding yarn is wound around the bobbin (3b) with the sandwiched portion formed by the friction member (36) and the gripping member (33) as the winding yarn starting end, and this portion is deviated from the normal winding position at the bobbin position. Since the yarn Y is lifted in the rotation direction, the continuous yarn Y 'extending from the full bobbin (3a) to the empty bobbin (3b) is given an appropriate tension and is cut by pressure contact with the yarn cutting blade (64) provided on the path. , As a result, full bobbins (3

(Effects of the Invention) According to the turret type winding device of the present invention, when the bobbin holder on the empty bobbin holding side moves from the doffing end position to the winding start position by continuous rotation of the turret board, immediately before the winding start position. The bobbin holder is continuously revolved from this point to the winding start position, so that the full bobbin symmetrical to the bobbin holder is also quickly moved to the doffing start position by the cam mechanism and Since the clutch is inactive and the spindle is simultaneously braked to prevent idle rotation of the full bobbin, the winding end of the full bobbin is prevented from whirling, and the whirling yarn end is wound into the empty bobbin. Can be prevented, and the clutch switching operation is accelerated only by the rotation of the turret board, so that it is possible to prevent the clutch switching mechanism from becoming complicated and to increase the cost of the apparatus. It also has the effect of suppressing.
