Description

[Detailed Description of the Invention] Field of Industrial Application The present invention relates to a traverse device used in a pirn winder.

〓Prior Art〓 One of the devices conventionally used as a traverse device for a pan winder is the following device.

Two package rows 52 and 53 in which a large number of winding package cages 51 are arranged side by side on a machine stand are provided back to back, and a traverse guide arm 54 common to the package rows 52 and 53 arranged back to back is provided. The traverse guide arm is swingably supported by a support shaft 55 provided at the center of the machine and extending in the longitudinal direction of the machine. By reciprocating the support shaft 55, the traverse guide arm swings and guides the yarn to the package 51.
6 and 56, the reciprocating motion of the traverse guide arm 54 causes them to constantly move up and down within a certain width. Therefore, if the size of the package 51, that is,
When changing the traverse width, the swing width of the traverse guide arm 54 must be changed, but if the swing angle of the traverse guide arm is changed in accordance with the package cages 51 of the package cage row 52 on one side, the swing width of the traverse guide arm 54 will change. The winding position does not match the package 51 of the side package row 53, and the package 51 cannot be rolled up. Therefore, when the support shaft 55 of one traverse guide arm 54 is provided at the center of the machine base, it is difficult to change the winding width of the package 51.

Further, when the package cage becomes large and the traverse width must be increased, the length of the traverse guide arm must be increased, which requires increasing the width of the machine base.

〓Problems to be solved by the invention〓 In view of the above points, the present invention simply changes the swing angle of the traverse guide arm in a traverse device that guides yarn to each of two rows of package cages arranged back to back. It is an object of the present invention to provide a traverse device in which the traverse width can be arbitrarily changed by simply changing the traverse device, and the traverse device does not significantly increase the machine width even though it is a double-row device.

〓Means for solving the problem〓 The traverse guide arm, which has a traverse guide at the tip and is provided for each package cage, can be swung parallel to the axial direction of the wind-up package cage and close to the wind-up package cage. The traverse guide arm support shaft is supported by a traverse guide arm support shaft, and two traverse guide arm support shafts are arranged in parallel so that the traverse guides of the traverse guide arms supported by the traverse guide arm support shaft are oriented in opposite directions. .

〓Operation〓 The traverse guide arm is supported by the traverse guide arm support shaft provided at the center of the package cage rows arranged in two rows on both sides, and each shaft on the left and right is separately connected to the traverse guide arm. The object is made to perform a rocking motion.

Thereby, by changing the swing angle of the traverse guide arm for each row separately, the traverse width can be changed for each row separately.

Moreover, between the package cage and the support shaft of the traverse guide arm that guides the thread to the package cage,
By providing a support shaft for the traverse guide arm that guides the yarn to the opposite package cage and allowing the traverse guide arms to overhang each other, the length of the traverse guide arm can be increased, which increases the length of the traverse guide arm compared to the increase in machine width. The traverse width of the package can be increased by

〓Example〓 Embodiments of the present invention will now be described with reference to the drawings.

The example shown in FIG. 1 is an example in which a servo motor 2 is used as an actuator 1, and the ball screw 3 is configured to rotate as the servo motor 2 rotates. A lifting block 4 is screwed onto the ball screw 3,
It moves up and down by the rotation of the ball screw 3.

A traverse guide arm 7 is fixed to a traverse guide arm support shaft 5 supported by a frame (not shown), approaching the wind-up package cages at intervals corresponding to the installation spacing of a plurality of rows of wind-up package cages 6. A traverse guide 8 is provided at the tip of the traverse guide arm 7. The traverse guide 8 moves up and down on a virtual plane parallel to the axial direction of the wind-up package 6 when the traverse guide arm 7 swings.

In the example shown in FIGS. 1 and 2, the winding package 6
Since each row of units is provided one row on each side of the machine base, the traverse guide arm support shaft 5 has two rows.
The books are set up in parallel. A drive arm 9 is provided at each end of the traverse guide arm support shafts 5, 5, and the arm 9 and the lifting block 4 are connected to a link 10.
are connected to form a link 11. The example shown in Fig. 3 is an example in which two unit rows of winding packages 6 are provided on each side of the machine base, and drive units provided at the ends of the traverse guide arm support shafts 5, 5, 5, 5, respectively. Connect arms 9, 9, 9, 9 1
0, 10, 12, and 12 are connected to form a link 11.

In the embodiment shown in FIG. 1, a servo motor is used as the actuator, but a fluid cylinder is provided instead of the servo motor, and a lifting block is fixed to the piston rod of the fluid cylinder. It is also possible to use an actuator that uses fluid to move the lifting block up and down by moving it forward and backward alternately.

Now, when the servo motor 2 rotates, the rotation is transmitted to the ball screw 3, which causes the lifting block 4 to move up and down, and the traverse guide arm support shaft 5 to reciprocate through the link 11.
Therefore, the traverse guide arm 7 swings back and forth and guides the yarn back and forth onto the winding package 6 by the traverse guide 8 at its tip.

When changing the diameter of the winding package, the rotation of the servo motor 2 is appropriately controlled, and the raising and lowering movement of the lifting block 4 is changed.
This is done by changing the swing angle of the In the illustrated example, the two parallel support shafts 5, 5 are rotated by one actuator, but if the support shafts 5, 5 are actuated by separate actuators, the parts on both sides can be rotated. It is also possible to change the size of

Moreover, between the package cage and the support shaft of the traverse guide arm that guides the thread to the package cage,
By providing a support shaft for the traverse guide arm that guides the yarn to the opposite package cage and allowing the traverse guide arms to overhang each other, the length of the traverse guide arm can be increased, which increases the length of the traverse guide arm compared to the increase in machine width. The traverse width of the package can be increased by

The traverse guide arm 7 swings around the traverse guide arm support shaft 5, and the traverse guide 8 at its tip reciprocates in an arcuate trajectory. The speed of movement in the parallel or traverse direction is constant.

The reason is as follows. In FIG. 4, the connecting rod 10 is assumed to be sufficiently long. Continuous rod 10 is constant speed
The speed of the tip 9' of the drive arm 9 when moving at V ₁ is V _b = 1/cosθ・V ₁ (from y direction speed = V ₁ ) The speed of the traverse guide 8 at the tip of the yarn guide arm 7 is V _c =l ₂ /l ₁・V _b −l ₂ /l ₁・cosθ・V _1The thread is traversed only by the y-direction component of the arc movement of the traverse guide 8, as shown in Figure 4. , the y-direction velocity component of the above V _c is V _cy =cosθ·V _c =l2/l1·V1 This becomes the traverse speed of the yarn. Since there is no θ, the speed is constant.

FIG. 5 shows a view from directly above where the yarn is wound around the winding package 6. As the traverse guide 8 approaches and moves away from the winding package 6 as shown in the figure, the winding angle changes from α to β. Because of this, the traverse speed will change slightly. However, this difference is very small and is canceled out by going back and forth, so it is not a problem.

〓Effects of the invention〓 The device of the present invention has a traverse guide at the tip and can swing the traverse guide arm provided for each package in parallel to the axial direction of the package to be wound up and close to the package to be wound up. In this way, two traverse guide arm support shafts are supported on a traverse guide arm support shaft, and two traverse guide arm support shafts are arranged in parallel so that the traverse guides of the traverse guide arms supported by the traverse guide arm support shaft are oriented in opposite directions. In addition, unlike a traverse device in which a traverse guide arm having traverse guides at both ends is supported on a single support shaft, the traverse width can be changed by appropriately changing the turning angle of the traverse guide arm support shaft. If the support shaft of the traverse guide arm that guides the yarn to the opposite package cage is provided between the package cage and the support shaft of the traverse guide arm that guides the yarn to the package cage, and the traverse guide arms are made to overhang each other, The length of the traverse guide arm can be increased,
The traverse width of the package can be increased compared to the increase in machine width.
