BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass fiber winding machine that winds glass fiber by alternately switching between two spindle collets.

0002

[Prior Art] Conventionally, for winding glass fiber, two spindle collets for winding the glass fiber are prepared, and when one collet is fully wound, the other collet is moved to the winding position and winding is performed. method is adopted.

To explain an example of switching such a fully wound collet, as shown in FIGS. 3 and 4, a pair of spindle collets 11 and 12 (the take-up tube is omitted) They are arranged symmetrically, and when the winding by one collet 11 becomes full, a full winding signal is issued and the turret 13 automatically moves 18 in the direction of the arrow.
Rotate 0 degrees and move one collet 12 to the winding position. Subsequently, winding is performed, and during this time the rolled up cheese is removed from the winding drum 11.

FIG. 4 shows the state immediately before the switching of the collets 11 and 12 is completed by reversing the turret 13, but the empty collet 1 that was originally on the left
2 to the right winding position,
A strand 17 is guided by a yarn guide bar 16 to waist winding parts (front caps) 14 and 15 attached to the tips of the collets 11 and 12, respectively, and between the 180 degree rotation of the turret 13, the front cap 14
Waist wrapping is performed. After the rotation is completed, a very short waist winding is performed on the front cap 15, and then the strand 17 is guided to the winding collet 12 by the thread guide bar 16, and the original winding is resumed. In addition, at the time of switching, the strand 17 is reliably wound around the front cap 15 of the empty take-up collet 12 brought to the winding position, and then the front cap 14 is
, 15, it is necessary to reliably cut the strand 17.

[0005]

However, in the conventional switching described above, when the winding collets 11 and 12 are reversed to state 2, as shown in the switching state FIG. Since the winding angle θ1 of the strand 17 around the front cap 15 was small, the winding could not be performed reliably.

[0006] In order to solve this problem, the shape of the front cap has been devised so that it can be wrapped easily (Utility Model Application No. 123559/1983), but even then, it is difficult to change the shape depending on the number and type of glass fiber. Mistakes were sometimes made.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide an apparatus that can accurately wind glass fibers when switching spindle collets.

[0008]

[Means for Solving the Problems] In order to solve the above problems, the present invention includes at least a pair of spindle collets arranged symmetrically around the center of rotation of the turret, so that one spindle collet can take up a full volume. In a glass fiber winding machine that switches the other spindle collet for winding, a rail is installed on a separator installed between the pair of spindle collets, and
The turret is characterized by having an auxiliary rod engaged with the rotation of the turret.

[0009] Here, the rails disposed on the separators are made of, for example, the same material as the separators, and are closely adhered to the separators with an adhesive or the like. A wire or chain, for example, is pulled within the rail to move the auxiliary rod. However, the present invention is not limited to this configuration, and any configuration may be used as long as the auxiliary rod can move along the rail.

[0010] The auxiliary rod may be anything that has sufficient stress to hook the glass fibers, such as a stainless steel rod whose shaft portion is engaged with the above-mentioned rail. The auxiliary rod is moved, for example, by driving the wire, chain, etc. mentioned above with a motor.

[0011]

[Operation] According to the structure of the present invention, when switching the spindle collet, the auxiliary rod is also driven along with the rotation of the turret and hooks the strand between the front caps, so that the winding angle of the strand to the front cap on the winding side is adjusted. can be made larger.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be explained based on the drawings. FIG. 1 shows a glass fiber winding machine for carrying out the present invention. Reference numeral 1 denotes a turret, which is attached to a front cover 8 and is rotated clockwise in the figure by a rotating device (not shown). A pair of spindle collets 2 and 2' are installed on the turret 1 so as to be driven to rotate symmetrically about its rotation center (the center point of the turret). Winding tubes 3, 3' are fitted into the collets 2, 2', and the rotation of the collet 2 (2') at the winding position causes the tube 3 (3'
) is wound around the strand 17. A traverse device 10 for winding the strand 17 around the tube 3 (3') in a traversing manner is attached to the front cover 8.

[0013] Furthermore, a separator 4 is provided protruding from the turret 1, which allows the winding tube 3 (3') to be
This prevents the yarn wound on the tube from scattering and wrapping around the other tube. Further, a rail 6 is closely attached to the separator 4, and an auxiliary rod 7 is fitted onto the rail 6.

The structure of the rail 6 and the auxiliary rod 7 is shown in FIG. FIG. 2 is a side view of FIG. 1, and for convenience, the winding tube 3,
The traverse device 10 and strand 17 are omitted. A wire 9 is pulled on the rail 6, and the wire 9
is driven by a motor M installed inside the front cover 8. If the motor M is also used for rotating the collet 1, the auxiliary rod 7 will be driven as the collet 1 rotates. The auxiliary rod consists of a bar 7' and a holder 7'' that fixes it, and the holder 7'' is hooked to a wire 9. Therefore, when the wire 9 is driven by the motor M, the holder 7'' moves on the rail 6. Note that 5 indicates a front cap.

With the above configuration, the spindle collets 2, 2
The switching of ' is performed as follows. First, as shown in FIG. 1, a strand 1 of glass fiber filaments spun from an upper glass melting tank (not shown) is placed in a take-up tube 3 of a spindle collet 2 on the right side.
Wind up 7. At this time, the position of the auxiliary rod 7 is
) in position (a).

[0016] When the right collet winds up the winding to a full volume, a full winding signal is issued, and the turret 1 rotates clockwise in Fig. 1 . In response, the auxiliary rod 7 is driven along the rail 6 and positioned in the direction of (b) in FIG. 6(a). Note that while the collet 2' on the left side is moved to the winding position on the right side, the strand 17 is guided to the front cap at the tip of the collet by a thread guide bar (not shown), as in the conventional case. In the present invention, the strand 17 is pushed upward by the movement of the auxiliary rod 7, so as shown in FIG.
As shown in b), the angle θ2 at which the strand wraps around the front cap of collet 2' increases, and collet 2 is braked, so collet 2,
The strand is easily wound onto the collet 2', aided by the difference in rotational speed between the collets 2'.

Turret 1 rotates 180 degrees and collet 2
' comes to the winding position, the auxiliary rod 7 moves to (c) in Fig. 6(a).
Wait at the position.

[0018] Depending on the number and type of glass fiber, automatic switching is possible with only the auxiliary rod and without the front cap.

[0019]

[Effects of the Invention] As explained above, according to the present invention,
When changing the spindle collet, glass fiber can be accurately wound around the collet without having to modify the shape of the front cap.

[0020] Furthermore, since the front cap can also be eliminated, a guide mechanism for guiding the strand to the front cap is no longer necessary, and the yarn on the front cap is treated as a waist yarn, so that the product is not made of glass fiber. can be eliminated.
