However, in conventional turret-type winding devices, when the fully wound spindle is transferred from the winding position to the standby position by rotation of the turret disk, the fully wound spindle may continue to rotate due to inertia in the standby position. was there.

Specifically, in the case of a structure in which each spindle is connected to a common drive motor via a clutch mechanism, the shaft of the spindle is connected at the winding position by connecting the clutch mechanism between the drive motor and the empty spindle. On the other hand, in the standby position, the clutch mechanism between the drive motor and the fully wound spindle is released to stop the rotation of the axis of the spindle. There was a risk that the spindle would become completely free from the drive motor and rotate due to inertia.

For this reason, the operator has to wait for the shaft rotation of the fully wound spindle in the standby position to stop before removing the yarn package from the spindle, which poses a problem in that the production efficiency of the yarn package decreases. Ta. Alternatively, if the operator manually stops the shaft rotation of the spindle in the standby position, there is a problem that not only is there danger to the operator, but there is also a risk of damage to the yarn package.

The present invention has been made in view of the above-mentioned problem, and when the spindles in the winding position and the standby position are relocated by rotation of the turret disk, the shaft rotation of the fully wound spindle in the standby position is immediately stopped. It is an object of the present invention to provide a turret-type yarn winding device that can safely and efficiently produce high-quality yarn packages.

In a turret-type winding device that switches the yarn from the fully wound spindle to the empty spindle and rewinds the yarn onto the empty spindle, the rotation of the turret disk causes the yarn to become full. The present invention is characterized in that a brake device is provided for forcibly stopping the axial rotation of the spindle from the outside during the process of relocating the spindle in the winding state while rotating from the winding position to the standby position.

According to this, when the fully wound spindle is rotated from the winding position to the standby position and relocated by rotation of the turret disk, the shaft rotation of the fully wound spindle can be stopped immediately.

Further, the brake device is provided around a standby position of the spindle,
When the fully wound spindle is placed in the standby position, the axial rotation of the spindle may be forcibly stopped.

Further, the brake device includes a contact portion that contacts the disk member of the spindle shaft, a support portion that supports the contact portion, and a biasing portion that biases the contact portion with a predetermined biasing force. It's okay. According to this, it is possible to reliably stop the axial rotation of the fully wound spindle with a simple configuration.

The spindle is connected via a clutch mechanism to the drive motor that rotates the spindle, and the brake device forcibly rotates the spindle when the clutch mechanism is disconnected. You can stop it. According to this, when the spindle becomes free from the drive motor due to disconnection of the clutch mechanism, the shaft rotation of the spindle is forcibly stopped, reducing the burden on the drive motor and brake device. .

Further, after the clutch mechanism is disconnected, the brake device starts to stop the shaft rotation of the fully wound spindle that has revolved from the winding position to the standby position due to the rotation of the turret disk. , the axial rotation of the spindle may be completely inhibited when the spindle is placed in the standby position. According to this, the fully wound spindle, which has revolved from the winding position to the standby position due to the rotation of the turret disk, can be reliably stopped at an appropriate position.

According to the present invention, when the fully wound spindle is rotated from the winding position to the standby position and relocated by rotation of the turret disk, the axial rotation of the fully wound spindle can be promptly stopped. Therefore, the operator can quickly remove the yarn package from the spindle placed at the winding position, making it possible to safely and efficiently produce high-quality yarn packages.

As shown in FIG. 1, the spindle 3 is supported in a cantilevered manner so as to protrude forward at a symmetrical position on a concentric circle of the turret disk 2, and is moved between the winding position A and the standby position B by the rotation of the turret disk 2. It is alternately relocated while orbiting.

The spindle 3 also includes a spindle shaft 31 that passes through the turret disk 2, a bobbin holder 32 that winds the yarn around the spindle shaft 31 on the front side of the base frame 1, and a spindle shaft 31 on the back side of the base frame 1. A disc member 33 is provided concentrically at the base end of the bobbin holder 32, and a grip portion 34 is provided on the base end side of the bobbin holder 32 to grip the yarn when switching the yarn.

Further, the spindle 3 is connected to a common second drive motor 200 provided in the base frame 1 via a second rotation transmission mechanism 20, and is moved to the winding position A according to a command from the control unit 6. It is designed to wind the thread from an empty state to a fully wound state while rotating the thread.

As shown in FIGS. 2 and 3, the second rotation transmission mechanism 20 includes a pulley 20a connected to a second drive motor 200, a belt 20b, one of which is wound around the pulley 20a, A pulley 20c wound around the other end of the belt 20b, a rotating shaft 20d connected to the pulley 20c at one end, a belt 20e wound around the other end of the rotating shaft 20d, and the belt 20e. Both pulleys 20f are connected to both spindle shafts 31 via a clutch mechanism 8, which will be described later. Thereby, the rotation of the second drive motor 200 is transmitted to each spindle 3 via the pulley 20a, belt 20b, pulley 20c, rotating shaft 20d, belt 20e, pulley 20f, and further the clutch mechanism 8.

Further, the spindle 3 is provided with a clutch mechanism 8 (dog clutch) consisting of a first clutch tooth 81 and a second clutch tooth 82 between the spindle shaft 31 and the second rotation transmission mechanism 20, and a control unit The clutch mechanism 8 is operated by the dock function linked to the operation of the turret board 2 commanded by the clutch mechanism 6. Specifically, when the spindle 3 is placed at the winding position A, the clutch mechanism 8 of the spindle 3 is in a connected state (a state in which the first clutch teeth 81 and the second clutch teeth 82 shown in FIG. 6 are engaged). ), the spindle 3 and the second drive motor 200 are rotatably connected via the second rotation transmission mechanism 20, so the spindle 3 at the winding position A winds the yarn while rotating. take. On the other hand, when the spindle 3 is placed in the standby position B, the clutch mechanism 8 of the spindle 3 is disconnected (the first clutch tooth 81 and the second clutch tooth 82 are separated as shown in FIG. 6). Since the connection between the spindle 3 and the second drive motor 200 is also released, the spindle 3 at the standby position B becomes free from the second drive motor 200 and stops rotating. In this embodiment, a dog clutch is used as the clutch mechanism 8, but other clutches such as a friction clutch or a fluid clutch may be used.

Further, the spindle 3 is provided with a gripping portion 34 on the proximal end side of the bobbin holder 32 for gripping the yarn. In this embodiment, the gripping part 34 is a gap on the proximal end side of the bobbin holder 32, and after the thread fits into a predetermined gap when switching the thread, the gap closes and the thread is held. By pinching, the yarn is gripped.

Further, the spindle 3 is provided with a cutter 7 around the base end side of the bobbin holder 32. When the fully wound spindle 3 at the winding position A and the empty spindle 3 at the standby position B are repositioned by rotation of the turret board 2 while rotating each other, the cutter 7 is moved from the fully wound spindle 3 to the empty spindle 3. When switching the yarn to the spindle 3 in the current state, the yarn is cut.

The traverse device 4 includes a traverse device main body 41 that projects forward from the base frame 1 along the axial direction of the spindle 3, and a traverse guide 42 that is provided on the traverse device 4. This traverse guide 42 is connected to a drive motor (usually a second drive motor 200 that rotates the spindle 3 on its axis) via a predetermined cam shift mechanism, and is connected to a drive motor (usually a second drive motor 200 that rotates the spindle 3 about its axis) through a predetermined cam shift mechanism. By reciprocating between the folding position and the folding position on the base end side, the yarn sent from outside the apparatus is guided to the spindle 3 which rotates at the winding position A while traversing.

Furthermore, when the traverse device 4 switches the yarn from the spindle 3 in a fully wound state to the spindle 3 in an empty state, the traverse guide 42 moves beyond the turning position on the proximal end side of reciprocating movement. The yarn is drawn toward the base end of the spindle 3, and after being gripped by the gripping portion 34 of the spindle 3, the yarn is moved back to the folding position on the base end side.

As shown in FIGS. 2 and 3, the brake device 5 is provided around the standby position of the spindle 3 on the back side of the base frame 1, and is attached to the axis of the spindle 3 that has revolved from the winding position A to the standby position B. Forcibly stop rotation.

Specifically, the brake device 5 is supported by a support frame 11, and includes a contact portion 51 that contacts the disc member 33 at the base end of the spindle shaft 31, and a support portion 52 that supports the contact portion 51. and a biasing portion 53 that biases the contact portion 51 with a predetermined biasing force.

The contact portion 51 consists of a head 51a made of a hemispherical resin member and a shaft portion 51b connected to the head 51a, and the head 51a is connected to the disk member 33 of the spindle 3 disposed at the standby position B. come into contact with. In this embodiment, the head 51a of the contact portion 51 is on the orbit from the winding position A to the standby position B of the spindle, and is located downward from a position extending horizontally from the center position of the turret board 2. The spindle 3 comes into contact when the spindle 3 revolves within an angle range of 10 degrees to 15 degrees with respect to the horizontal direction. Therefore, the contact portion 51 can reliably contact the disk member 33 of the spindle 3 that has revolved from below from the winding position A to the standby position B.

Further, the support portion 52 is fixed to the support frame 11 so as to support the contact portion 51 in a movable manner in the axial direction of the shaft portion. In this embodiment, the support portion 52 supports the contact portion 51 such that the shaft portion 51b of the contact portion 51 is slightly inclined upward with respect to the horizontal direction. Therefore, the contact portion 51 can contact the disc member 33 without interfering with the revolution of the spindle that has revolved from below from the winding position A to the standby position B.

The biasing portion 53 is a spiral spring member through which the shaft portion of the contact portion 51 is inserted, and is provided in a compressed state between the head portion 51a of the contact portion 51 and the support portion 52. , the contact portion 51 is biased toward the disk member 33 of the spindle 3 at the winding position A.

When the fully wound spindle 3 is relocated from the winding position A to the standby position B, the contact part 51 is applied with a predetermined urging force by the urging part 53 to the disc member of the spindle 3 in the standby position B. By contacting the peripheral surface of 33 in a pressed state, the axial rotation of the spindle 3 at the standby position B can be forcibly stopped from the outside by frictional force.

Next, the entire yarn winding operation by this device will be explained.

First, after the empty spindle 3 at the winding position A grips the yarn, the empty spindle 3 winds the yarn while rotating, until the yarn is fully wound into a package with a predetermined diameter. Continue winding the strip.

When the spindle 3 at the winding position A becomes fully wound, the fully wound spindle 3 is rotated from the winding position A to the standby position B and relocated by rotation of the turret board 2, and is placed in the empty state. The spindle 3 is changed from the standby position B to the winding position A while being rotated.

Then, after switching the yarn from the fully wound spindle 3 at the standby position B to the empty spindle 3 at the winding position A, the yarn is newly wound onto the empty spindle 3, and the yarn is completely wound again. Remove the yarn package from the spindle 3 while pulling it out.

Next, the braking operation of the brake device 5 when the fully wound spindle 3 is changed from the winding position A to the standby position B will be described with reference to FIG.

First, as shown in FIG. 6(a), when the fully wound spindle 3 has revolved from the winding position A to just before the standby position B, the contact portion 51 of the brake device 5 is connected to the disk of the spindle 3. It is not in contact with the peripheral surface of the member 33. At this time, since the clutch mechanism 8 is still in the connected state, the spindle 3 continues to be rotated by the second drive motor 200.

Then, as shown in FIG. 6(b), when the spindle 3 in the fully wound state further revolves, the contact portion 51 of the brake device 5 starts to contact the circumferential surface of the disc member 33 of the spindle 3. The rotation of the shaft begins to forcibly slow down. At this time, since the clutch mechanism 8 is disconnected, the spindle 3 is free from the second drive motor 200, and the spindle 3 is not rotated by the second drive motor 200.

Then, as shown in FIG. 6(c), when the spindle 3 in the fully wound state further revolves and completely reaches the standby position B, the contact portion 51 of the brake device 5 applies a predetermined biasing force to the disc of the spindle 3. Since it contacts the circumferential surface of the member 33 in a pressed state, the axial rotation of the spindle 3 is forcibly stopped by frictional force. At this time, the clutch mechanism 8 remains disconnected, the spindle 3 is completely free from the second drive motor 200, and the brake device 5 completely stops the shaft rotation. .

After that, after the yarn package is removed from the spindle 3 at the standby position B, when the spindle 3 at the winding position A becomes fully wound, the spindle 3 in the empty state is moved by the rotation of the turret board 2 as shown in FIG. It starts to revolve upward from the standby position B shown in (c), but the contact part 51 of the brake device 5 is pushed by the spindle 3 and retreats radially outward while resisting the urging force of the urging part 53. Therefore, the spindle 3 can smoothly revolve from the standby position B to the winding position A.
