A spring 8 for pressing the cradle arm 6 so that the bobbin is held from both sides by the bobbin holder 10 of the cradle arm 6 and the bobbin holder 9 of the cradle arm 4;
A stopper mechanism 11 stops the cradle arms 4 and 6 at a predetermined position, and a stopper 12 stops the cradle arms 4 and 6 at a doffing operation position.

When the cradle arms 4 and 6 are rotated in the direction (a), the arm 5 comes into contact with a stopper 12 protruding from the support member 2 to stop the cradle arms 4 and 6 at the doffing operation position. It is made to let. Further, a damper plate 14 of a vibration prevention mechanism 13 is provided on the support member 2 along the cradle arms 4 and 6.

The cradle arms 4 and 6 are driven by a driving device (not shown) connected to the shaft 3 or manually (a).
Or (b) direction. The cradle arms 4 and 6 are provided with a brake mechanism (not shown) for stopping the rotation of the bobbin holders 9 and 10, and a sliding member 15 that slides on the damper plate 14.

Above the cradle arms 4 and 6, an empty bobbin supply mechanism 16 is provided.

The arm 5 is provided with a protruding member 17 which comes into contact with the stopper mechanism 11. The protruding member 17 is rotatably mounted on the shaft 18 protruding from the arm 5. The roller 19 is formed. The roller 19 uses a bearing, a metal roller, or a synthetic resin roller. It is possible to form the projection member 17 only with the shaft body 18.

The stopper mechanism 11 has a pin 21 projecting therefrom and a stopper 20 rotatably attached to the support member 2 by a shaft 22, an electromagnetic solenoid 24 attached to the support member 2 by a bracket 25, The operation arm 26 attached to the operation shaft 24a of the electromagnetic solenoid 24 by the pin 27 and the stopper 20 are rotated in the direction (C), and the contact portion 20a of the stopper 20 is rotated by the rotation of the roller 19 provided on the arm 5. And a spring 23 positioned on the moving path.

The stopper 20 is a brake mechanism (not shown)
It is preferable that the cradle arm 4 is installed at a position where the rotation of the cradle arms 4 and 6 is stopped after the operation of the cradle arm.

When the pin 21 protruding from the stopper 20 is engaged with the long hole 26a of the operation arm 26 and the operation shaft 24a of the electromagnetic solenoid 24 is retracted, the stopper 20 is moved to (d).
As a result, the contact portion 20 a is moved in a direction deviating from the rotation locus of the roller 19 provided on the arm 5.

It is possible to provide the roller 19 on the cradle arm 4 and stop it at a predetermined position by the stopper mechanism 11.

In the stopper mechanism 11 described above, the stopper 20 is rotated. However, it is possible to move the stopper 20 in the longitudinal direction of the bobbin so as to deviate from the rotation locus of the roller 19. Further, a fluid cylinder using compressed air or the like can be used instead of the electromagnetic solenoid 24 for rotating the stopper 20, and a wire or the like is connected to the stopper 20, and an operator pulls and rotates the wire. Can be The operation of the electromagnetic solenoid 24 and the like can be performed based on a signal from a control device or a manual switch in addition to a signal from a timer.

When the stopper 20 is rotated from the position on the rotation locus of the roller 19 to a position outside the rotation locus of the roller 20, the operating shaft 2 of the electromagnetic solenoid 24 is rotated.
Since the stroke of the stopper 4a becomes longer, the rotation of the stopper 20 is divided into a rotation part by the electromagnetic solenoid 24 and a rotation part by the movement of the roller 19 accompanying the rotation of the cradle arms 4, 6. The stroke of the operating shaft 24a of the electromagnetic solenoid 24 can be shortened.

When the empty bobbin held by the above-described bobbin holders 9, 10 abuts against the rotating roller 28 with a predetermined surface pressure and rotates, the yarn is traversed by the traverse device 29 and wound on the bobbin. ing.

When winding the yarn with a winding machine in which the above-mentioned cradle device 1 is installed, an electromagnetic solenoid 24 is used.
Is turned off, the stopper 20 is pressed by the spring 23, and the contact portion 20a is positioned on the rotation locus of the roller 19. At this time, the pin 21 is
6 is movable in the long hole 26a, and the working shaft 20a is protruded by contacting the end of the long hole 26a. When a predetermined amount of thread is wound on the bobbins held by the bobbin holders 9 and 10 in this state, the cradle arms 4 and 6 are rotated in the direction (a) by a driving device (not shown) or manually. The bobbin holders 9 and 10 holding the packages are moved toward the doffing operation position.

When the cradle arms 4 and 6 are rotated to predetermined positions, the rollers 19 provided on the arm 5 contact the contact portions 20a of the stopper 20 as shown in FIGS. The rotation of the cradle arms 4 and 6 is stopped by contacting the surface 20a-1. When a preset time (time during which the rotation of the bobbin holders 9 and 10 is reliably stopped by the operation of the brake mechanism (not shown)) elapses after the cradle arms 4 and 6 stop, the control device (shown in FIG. 7), the electromagnetic solenoid 24 is actuated, the operating shaft 24a is retracted, and the stopper 20 is rotated in the (d) direction by the operating arm 26 as shown in FIGS. 20a is slightly shifted from the rotation locus of the roller 19. When the cradle arms 4 and 6 are rotated in the direction (a) in this state, the roller 1
9 pushes over the end of the contact portion 20a of the stopper 20 and gets over it, and the stopper 20 is rotated as shown in FIGS. At this time, the pin 21 protruding from the stopper 20 moves in the long hole 26 a of the operation arm 26.

The cradle arms 4, 6 rotate as they are, and the bobbin holders 9, 10 are moved toward the doffing operation position. When the arm 5 comes into contact with the stopper 12 and the rotation of the cradle arms 4 and 6 is stopped, the cradle arm 6 is rotated in the longitudinal direction of the bobbin around the shaft 7 to perform the doffing operation of the package. .

In the above operation, the cradle arm 4,
The electromagnetic solenoid 24 is released after the 6 has passed through the stopper 20 or when it has been turned to the doffing operation position, and the contact portion 20 a of the stopper 20 is moved on the turning locus of the roller 19 by the spring 23. The operating shaft 24 is projected by the pin 21.

When the doffing operation described above is completed, the cradle arms 4, 6 are rotated in the (B) direction, and the bobbin holders 9, 10 are moved toward the winding operation position. When the cradle arms 4 and 6 are rotated to reach a predetermined position, the roller 19 abuts against the contact surface 20a-2 of the contact portion 20a of the stopper 20, and the rotation of the cradle arms 4 and 6 is stopped. An empty bobbin is supplied to the bobbin holders 9 and 10 by the bobbin supply mechanism 16.

When the empty bobbin is held by the bobbin holders 9, 10, the electromagnetic solenoid 24 operates to retract the operating shaft 24a, and the cradle arms 4, 6 rotate from the intermediate stop position to the doffing operation position. As in the case described above, the stopper 20 is rotated in the direction (d) by the movement of the roller 19, and the contact portion 20 a is moved out of the rotation locus of the roller 19.

When the cradle arms 4 and 6 are rotated in the (B) direction and the empty bobbins held by the bobbin holders 9 and 10 are moved to the winding operation position, the yarn is wound.

When the empty bobbin supply operation is performed at the same position as the doffing operation, the contact portion of the stopper 20 is provided so that the cradle arms 4 and 6 can rotate from the doffing operation position to the winding operation position. The roller 20a is positioned outside the rotation locus of the roller 19.

Since the operation arm 26 has the elongated hole 26a, the stopper 20 can be used without operating the electromagnetic solenoid 24 in the event of trouble during winding or maintenance work when the machine is stopped. The cradle arms 4 and 6 can be freely rotated by manually rotating the cradle arm 20 to position the contact portion 20a outside the rotation locus of the roller 19.

[0032]

According to the cradle device of the present invention, a stopper mechanism for stopping the rotation of the cradle arm is provided between the winding operation position and the doffing operation position. After the rotation of the bobbin holder is stopped by the brake mechanism, the bobbin holder can be moved to the doffing operation position, regardless of the rotation of the cradle arm by the drive mechanism or the rotation of the cradle arm manually, damaging the yarn layer of the package, The bobbin holder, the cradle arm and the like can be prevented from being damaged.

Further, since the cradle arm can be stopped during the rotation from the doffing operation position to the winding operation position, the configuration of the empty bobbin supply mechanism can be simplified.

[0034] The cradle device of the present invention is characterized in claim 2.
The stopper mechanism is rotated between the cradle arm or the cradle arm mounting arm and a projecting member provided on the cradle arm, and the machine frame or the supporting member so that the projecting member can come into contact with the cradle arm during rotation. Since the cradle arm is constituted by the stopper member movably or movably mounted, the cradle arm can be reliably stopped during the rotation.

Further, since the cradle arm can be stopped during the rotation from the doffing operation position to the winding operation position, the structure of the empty bobbin supply mechanism can be simplified.
