Description of the Related Art As shown in FIG. 18, in an automatic winder as a winding device, a traverse drum 8 provided on an upper part of a winding unit 2 is made to contact a paper tube 6 supported by a cradle 3. At high speed, the yarn Y from the yarn supplying bobbin 7 provided at the lower part is wound up to form a package P having a predetermined shape. Then, the rolled-up package P is discharged onto a discharge conveyor 4 provided behind the winding unit 2,
The new paper tube 6 held in the paper tube stocker 5 is replaced and the next winding operation is performed.

[0003] Assuming that the paper tube replacement is performed automatically,
A doffing device 1 that travels along the direction in which the winding units 2 are arranged is known. In this doffing device 1, the cradle 3 is opened by an arm lever (not shown) to discharge the package P that has been fully wound, and the paper tube 6 of the paper tube stocker 5 is gripped by a chucker (not shown) to cradle the cradle 3. It is designed to be attached to. At the time of discharging the package P, as shown in FIG. 19, the wound package P is appropriately rotated by the traverse drum 8, and the yarn Y traversing left and right between the traverse drum 8 and the filler 9 is formed. The yarn Y is cut into a pick-up guide (not shown). Then, the lower side of the cut yarn Y is grasped and hooked on the paper tube 6 newly attached to the cradle 3 so that the next winding can be started immediately.

[0004]

By the way, in order to form the cone-shaped package P, the tapered paper tube 6 is used, but the cradle 3 makes the package P contact the traverse drum 8. When the paper tube 6 is unfolded rearward from the to
The direction of the mounting shaft differs depending on the taper angle. For this reason, there is a problem that the doffing device 1 in which the paper tube 6 is mounted by the chucker of a constant operation cannot be used when the type (taper angle) of the package P changes. As a countermeasure against this, a structure in which the chucker can be adjusted according to the posture of the cradle 3 at the exchange position is conceivable, but this would lead to complication and weight increase of the doffing device.

In addition, a rear package detection sensor 112 for detecting the presence or absence of an obstacle such as a package is provided on the rear side R of the unit on the inclined portion 13c of the traveling carriage 13. When the obstacle is detected, the winding unit 11 becomes full. Even if it stops after sensing, it does not doffing and bypasses and starts running. In addition, traveling carriage 13
A human body detection sensor 113 is provided on both side frames 38, and when an obstacle is detected, the vehicle stops traveling and travels to a direction where there is no obstacle.

Further, signals such as rising / lowering of the cradle 16, ON / OFF of the package brake, and timing of drum start are output from the traveling carriage 13 side to the winding unit 11 side. Further, the cam shaft 64 is provided with an origin cam (not shown), a cradle up / down signal and a drum start signal cam, a package brake timing cam, an operation timing cam of the swinging motor 49, and a rotation direction support cam, and the cam shaft 64 rotates once. By doing so, these cams operate to complete the doffing operation.

Next, the operation of doffing the automatic winder with this doffing device will be described. When the winding unit 11 during winding is full, the knotting operation is started, and when this is successful, the knotting operation is stopped and the light emitting sensor 10 of the lower rail 37 is stopped.
1 operates and a full pipe command is issued. When the traveling carriage 13 that is traveling or stopped moves and the light receiving sensor 102 senses it, the traveling motor 63 is switched from high speed to low speed, and at the same time, the index IN solenoid 106 is activated. When the traveling carriage 13 moves at a low speed and moves to the unit fixed position, the index plate 105 fits into the index pin (not shown), the index IN confirmation sensor 107 operates, and the traveling motor 63 completely stops. The index IN solenoid 106
Stops the energization when the index IN confirmation sensor 107 operates.

When the traveling carriage 13 stops at a predetermined position, the doffing operation is started for the winding unit 11. That is, when the index IN confirmation sensor 107 enters, the cam shaft 64 starts to rotate due to the driving of the cam shaft motor 63. Then, a signal for starting doffing is issued from the traveling carriage 13 side to the winding unit 11 side, and the electromagnetic valve of the air cylinder 25 is operated to discharge the air from the upper air supply / discharge port 26 as shown in FIG. The piston rod 30 is extended upward with. This is lever 73
Rotates clockwise in the figure, the cradle 16 rises,
The full package P is separated from the traverse drum 8. At this time, the package brake is also operated at the same time to stop the rotation of the package P and prevent the yarn Y from becoming loose. The signal to the winding unit 11 is a light emitting sensor on the side of the traveling carriage 13.
It is performed by transmitting to the light receiving sensor 104 of the rail 37 below 103. The package brake is performed by urging the bearing center 20a toward the paper tube by an air cylinder (not shown). Next, the swinging motor 49 of the thread take-up means 14 is rotated, and the guide wire 47 is once moved in the left direction shown by the solid line in FIG. Then, the guide arm 46 is lowered to pick up the yarn Y between the package P and the traverse drum 8. That is, after the guide arm 46 descends, the guide wire 47
Oscillate to the right and hook the thread Y.

Next, as shown in FIG. 7, when the guide wire 47 takes the yarn Y, the guide arm 46 moves up,
The yarn Y is lifted and brought to a position near the clamp cutter 15 which has slightly advanced to the unit rear side R. At this time, by supplying air to the upper air supply / discharge port 26 of the air cylinder 25, the piston rod 30 is retracted, and the raised cradle 16 is lowered slightly or to a position where it comes into contact with the traverse drum 8, and P to guide plate 3
4 so that it can be rolled gently. In this state, as shown in FIG. 8, the clamp cutter 15 is closed to cut the yarn Y lifted by the guide wire 47, and at the same time grip the lower yarn (the yarn on the yarn supplying side). Next, the cradle opener 17 descends, and the engaging plate 74 engages with the cradle handle 24 by its opening operation to retract the bearing center 20a of the large diameter side fixed arm 21. Then, as shown in FIG. 9, the package P comes off the bearing centers 20a and 20b, rolls on the guide plate 34 by its own weight, and is placed on the package conveyor 33. This package P is a package conveyor 33
Is delivered to the machine edge.

Next, as shown in FIG. 10, when the cradle opener 17 is returned and the cradle 16 is closed, the cradle 16 further descends to a position where it comes into contact with the traverse drum 8. Then, the clamp cutter 15 advances to the unit rear side R with the yarn Y clamped. Before the clamp cutter 15 moves, the guide arm 46 descends slightly, and the guide wire 47 descends below the clamp cutter 15 while the yarn Y is still hooked to guide the yarn Y, so that The yarn end is easily caught between the bearing center 20a and the bearing center 20a. Then, as shown in FIG. 11, the bearing center 20 of the cradle 16 is
The cradle 16 is moved up to the paper core mounting position Q in order to mount a new paper core 12 on a and 20b. At this time, the cradle opener 17 also rises to a position where the cradle handle 24 is engaged, and the bearing center 20a of the cradle 16 is retracted.

Next, as shown in FIG. 12, the stocker pushing lever 78 descends to push down the stocker 77 and bring the paper tube 12 to the cradle 16. At this time, the paper tube holding rod 79 also descends at the same time, and the leading paper tube 12a
Only the cradle 16 is divided so as to be gripped.
When the stocker 77 descends and the paper tube 12a is positioned coaxially with the bearing center 20a, the cradle opener 17 returns to retract the bearing center 20a of the large diameter side fixed arm 21 and chuck the paper tube 12a. Simultaneously with this chuck, the yarn Y is sandwiched between the paper tube 12a and the bearing center 20a. When the yarn Y is held in the cradle 13, the clamp cutter 15 opens to release the yarn ends. At this time, the package brake is activated so that the bearing center 20a reliably sandwiches the yarn end with the paper tube 12a.

When the paper tube 12a is attached to the cradle 16, the cradle 16 is lowered and the chucked paper tube 12a is removed from the tip end side of the stocker 77, as shown in FIG. In addition, the paper tube holding rod 79 holds down the second and subsequent paper tubes 12 from falling. As the cradle 16 descends, the guide wire 47 rises while hooking the yarn Y so that the yarn Y does not slacken, and its yarn path is attached to a bunch guide (not shown) attached to the bearing center 20a of the cradle 16. ). A drum motor (not shown) starts rotating by the time the cradle 16 descends and the paper tube 12a comes into contact with the traverse drum 8. When the paper tube 12a comes into contact with the traverse drum 8, the yarn Y to which an appropriate tension is applied by the guide wire 47 is wound around the end of the paper tube to perform bunch winding. And FIG.
As shown in FIG. 5, the guide wire 47 descends as the bunch winding progresses. When the bunch winding is finished,
The guide wire 47 rotates counterclockwise while descending, and rises when the hooked yarn Y is removed, and the main winding of the yarn Y is started. When the main winding is started, as shown in FIG. 16, the stocker 77 returns to the original position by raising the stocker pushing lever 78, and the clamp cutter 15, the cradle opener 17, the guide arm 46, and the guide wire 47 are moved. The respective carriages return to their original positions and are housed in the traveling carriage 13.

When the cam shaft 64 makes one rotation and then stops, the doffing operation ends, and the index O which was in the IN state is stopped.
When the UT solenoid 108 turns ON, the index plate
105 is removed from the index pin, index OUT
The confirmation sensor 109 is turned on, and the traveling motor 63 is turned on again.
, The traveling of the traveling vehicle 13 is started.

As described above, when the attitude control means 95 is provided, when a new paper tube 12 is mounted on the cradle 16, the paper tube mounting position Q is always constant even if the taper angle of the paper tube is different. Because of the posture, the doffing device can be shared regardless of the taper angle of the paper tube. Also,
As for the paper tube supply means 18, other parts can be made common by only slightly changing the shape of the stocker 77 according to the taper angle. That is, it can be widely applied to packages P having different taper angles and is extremely versatile.
Further, since the attitude control means 95 is provided on the winding unit 11 side, the entire doffing device can be made compact and lightweight, high speed traveling is possible, and speeding up of doffing is achieved. In addition, adjustment work such as installation can be performed for each winding unit 11, which facilitates installation and handling.

The doffing device in this embodiment is
Since the yarn collecting means 14 for collecting the yarn Y connected to the doffed package P between the package P and the traverse drum 8 is provided, the yarn can be reliably picked up regardless of the remaining amount of the yarn supply. It is possible to prevent the mistake of doffing.
Further, in the conventional doffing device shown in FIGS. 18 and 19, when picking up a yarn, the yarn is caught by the yarn guide G provided on the yarn entering side of the traverse drum 8 in order to prevent the end face from falling. There was a problem, but this device does not have such a problem. This doffing device is particularly useful when the yarn of one yarn supplying bobbin (including the package shape) is rewound into one winding package. That is, in this type of winding, since the yarn feeding is also exchanged after the winding of the fixed length is finished, the doffing device for picking the yarn by the traverse shown in FIGS. This means that a large amount of this yarn will be wound around the package P. For this reason, conventionally, it was necessary to remove the wound different kinds of yarns in a post process, but according to the doffing device of the present invention, the package P
The yarn is not excessively wound around, and the post-process can be simplified.

Since the guide wire 47 which swings in the direction traversing the yarn path is provided as the yarn take-up means 14, the yarn Y can be hooked and captured easily and reliably with a simple structure. Shortening of the doffing process is achieved. Further, since the guide wire 47 guides the yarn Y to the end of the paper tube 12 and performs bunch winding, a yarn guiding means for bunch winding becomes unnecessary. Since the rotation of the paper tube 12 at this time is performed by the traverse drum 8, a separate paper tube rotation mechanism such as a drive roller is not required.

In addition, since the traveling rails 36 and 37 for traveling the bogie are two in the upper and lower directions, the structure is strong against left and right vibrations, and the traveling rails 36 and 37 can be reduced in weight. The unit full signal is not sent by the conventional green lamp, but the photoelectric sensor (10
Since the signal is transferred at 1, 104), the low speed region can be extended by increasing the speed of the detection of the full unit during traveling, and the normal traveling speed can be increased.

In the doffing device of this specific embodiment, the paper tube supply means is constituted by the stocker 77, but it is equipped with a chucker for gripping the paper tube held in the stocker and supplying it to the cradle. You may do it. This chucker can have a simple configuration in which the operation of mounting the paper core is constant.

[0041]

In summary, according to the first aspect of the present invention,
Even if the taper angle of the package changes, the attitude of the winding tube support member at a predetermined position can be made constant, the winding tube can be easily supplied, and the doffing device can be commonly used. Shows excellent effects. Further, according to the invention of claim 2, the entire doffing device can be made compact and lightweight, high speed traveling is possible, and speeding up of doffing is achieved.
