However, in this filling winding, since the yarn Y reciprocates up and down once in the traverse guide 5 and the yarn Y reciprocates between the peripheral surface of the bobbin 2 and the outer periphery of the pan 6, the winding speed of the wound yarn is reduced. , It becomes slow near the bobbin 2 and becomes fast on the outer peripheral side of the pan 6, so that the yarn is wound more densely on the outer peripheral side of the pan 6 and conversely, the yarn is loosely wound on the bobbin side, which is a good pan.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

In FIG. 1, although not shown, the spindle 1 is rotated by contacting the belt in units of, for example, 8 spindles,
The bobbin 2 mounted on the spindle 1 is rotated.

A traverse guide 5 for guiding a yarn Y from a yarn supplying package (not shown) is connected to a traverse bar 4 and is moved up and down with a predetermined traverse width with respect to the bobbin 1 by an elevating device 3. It is like this. That is, the traverse bar 4 has its both ends suspended by a chain 7 or the like so as to be able to move up and down, and the other end of the belt 7 is guided by pulleys 8 and 8 and connected to a ball nut 9, and the ball nut 9 is It is provided by being screwed into a ball screw 11 connected to the forward / reverse rotation motor 10, and the forward / reverse rotation of the forward / reverse rotation motor 10 causes the forward / reverse rotation of the ball screw 11 and the upward / downward movement of the ball nut 9 to traverse the belt 7. The guide 5 can be moved up and down with a predetermined traverse width.

The forward / reverse rotation motor 10 is controlled by the controller 13 to rotate in the forward / reverse rotation direction. The rotation of the forward / reverse rotation motor 10 is detected by the rotation sensor 12, and the rotation sensor 1
The detected value of 2 is input to the control device 13.

The traverse guide 5 is provided with a winding diameter sensor 14 such as a laser distance sensor for detecting the winding diameter of the pan 6, and the measured value is input to the control device 13. Winding diameter of positions that wound yarn is adapted to be measured by providing the winding diameter sensor 14 for measuring the winding diameter on the traverse guide 5. The rotation of the spindle 1 is detected by the spindle rotation sensor 15, and the detected value is detected by the controller 13
Is input to and the rotation speed of the spindle 1 is controlled based on the input.

In FIG. 1, the spindle 1 is rotated,
The yarn Y from the yarn supplying package P is guided by the traverse guide 5, and at the position of the traverse guide 5, the yarn Y is wound around the bobbin 1 to form the awn 6. On this occasion,
The control device 13 detects the traverse position of the traverse guide 5 from the detection value of the rotation sensor 12 and controls the forward / reverse rotation and rotation speed of the forward / reverse rotation motor 10 to sequentially keep the traverse guide 5 at a predetermined traverse width. The filling winding is controlled to move the traverse width upward, and at the same time, the rotation number of the spindle is increased or decreased according to the traverse position of the traverse guide 5 in the traverse width so that the filling winding is controlled at a constant yarn speed.

The rotation control of the spindle 1 according to the vertical position within the traverse width of the traverse guide 5 will be described in more detail.

FIG. 3 (a) shows a profile of the wound pan 6, and in the case of filling winding,
The pan 6 can be formed by sequentially moving upward with a predetermined traverse width. When the traverse guide 5 moves up and down with a predetermined traverse width, the yarn is wound near the outer diameter end 6d of the awn 6 at the lower end of the traverse width, and the yarn is wound around the bobbin side 6e at the upper end, so the traverse guide 5 When the yarn 5 reciprocates between the lower end position B and the upper end position A in the traverse width TW, the yarn reciprocates between the outer position of the yarn layer and the inner bobbin outer peripheral position, and the yarn winding speed changes.

Therefore, as shown in FIG. 2, the traverse guide 5 has its lower end position B in the traverse width TW.
In the case of reciprocating between the upper end position A and the upper end position A, in order to wind the yarn at a constant yarn speed, the spindle speed may be increased or decreased according to the traverse position.

Next, the range of increase / decrease of the spindle rotational speed will be described by taking as an example the case where the lower abacus-shaped conical portion 6a of the pan 6 is formed and the straight portion 6c up to the upper tapered portion 6b is wound up. To do.

Now, as shown in FIG. 3A, the bobbin 2
Radius r ₀ of the r ₁ radius of pirn 6, when the winding position is wound by the yarn speed Ys constant even change, spindle speed P ₀ o'clock radius r ₀ is, P ₀ = Ys
/ 2πr ₀ , and the spindle rotation speed P ₁ at the radius r ₀ is P ₁ = Ys / 2πr ₁ , and therefore the spindle rotation speed P is increased during the movement from the upper end position A to the lower end position B of the traverse width. _{To set 0} to P ₁ , (Ys / 2πr
_0- Ys / 2πr ₁ ), the rotational speed may be reduced by 1
The traverse width is 1 / 2Ys (1 / πr ₀ −1 / π
It is understood that the spindle rotation speed should be increased or decreased within the range of r ₁ ).

When the winding diameter at the position where the yarn is wound is indirectly measured by the traverse position as described above, the control of the spindle rotational speed becomes complicated when the abacus ball-shaped conical portion 6a is wound. It is preferable to do the following.

That is, the winding diameter at the position where the yarn is wound is directly measured by the sensor 14, and the rotation speed of the spindle is controlled according to the measurement result. By doing so, not only the straight line portion 6c but also the spindle rotation speed when winding the conical portion 6a can be easily controlled.

[0021]

In summary, according to the present invention, by controlling the number of rotations of the spindle in accordance with the winding diameter of the position where the yarn is wound, even if the yarn is wound at a position where the inner and outer diameters of the bun are different. The speed becomes constant, and it becomes possible to form a good pan shape.
