The thread is laminated on the predetermined section from the vicinity of the start end of the thread by superimposing it again and polymerizing the wound or horizontally wound thread toward the one end position and performing the winding operation of the thread. Therefore, there is no risk of being unraveled without fixing the starting end.
According to this method, since the process of fixing the starting end is not necessary, it is possible to contribute to the improvement of work efficiency.
In addition, since the winding is divided into the number of forward windings in the outward path and the number of backward windings in the return path, the end of the filamentous material comes to the first winding frame when the winding to the entire winding frame is completed. And the number of turns on each winding frame can be stabilized.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best mode for carrying out the invention will be described based on examples shown in the drawings. The embodiment is not limited to the following.
FIG. 1 is an explanatory view of a winding frame body that implements the winding method according to the present invention, and FIG. 2 is an explanatory view that graphs the winding position of the filamentous material.
In the present invention, a plurality of winding frames are arranged in parallel on the same axis. For example, in FIG. 1, the second winding frame (20), the third winding frame (30), in order from the first winding frame (10), Four winding frames of the fourth winding frame (40) are arranged in parallel. Each of the four lanes in FIG. 2 also corresponds to the above-described winding frame. Further, the horizontal axis in FIG. 2 is the rotation angle of the winding frame assembly. The winding frame assembly composed of these winding frames rotates at the same time, and the filamentous material is wound over the winding width of the winding frame by a predetermined number of turns for each winding frame.

In the traversing operation by the winding method according to the present invention, first, the filamentous material introduced into one end (11) of the first winding frame is horizontally laid up to the other end (12) on the opposite side in the winding width direction. . In FIG. 1, for convenience of explanation, it is shown that a substantially half-circular divided filament is wound. However, preferably, the axial movement speed of the filament is increased as shown in FIG. It is better to lay it horizontally so that it is parallel to the axis so that the number of turns can be detected accurately.
In order to accurately detect the number of windings, the next traverse operation may be performed after winding for one time, for example, at the time of movement of the winding width.

In any case, after moving to the position of the other end (12) of the first winding frame, the filamentous material is taken up again to the position of the one end (11). At this time, a predetermined section from the starting end of the filamentous material is horizontally mounted or wound, and the filamentous material is wound in a form of being polymerized thereon, so that the starting end is fixed without unraveling.
Then, after winding the prescribed number of turns around the first winding frame (10), the filamentous material is moved to one end (21) of the second winding frame (20), and the prescribed number of turns is turned from the one end (21). Wind. It is preferable that the number of windings be a predetermined number when the second winding frame (20) is wound to the other end (22).

  As for the number of windings on each winding frame body, a predetermined number of windings may be wound at once, but in the present invention, the winding of the forward path from the first winding frame body (10) toward the fourth winding frame body (40) is performed. After the turn, the return path can be wound again from the fourth frame body (40) to the first frame body (10), so that the specified number of times is wound separately for the forward path and the return path. May be.

In order, after moving from the other end (22) of the second winding frame (20) to one end (31) of the third winding frame (30), the specified number of turns is transferred to the third winding frame (30). It winds and moves from the other end (32) to one end (41) of the fourth winding frame (40).
In the fourth winding frame (40), after winding the prescribed number of turns to the other end (42), the winding is continued until the predetermined number of turns is reached.
Then, the filamentous material is moved from the position (43) at which full winding is detected to the other end (32) of the third winding frame, and is wound around the third winding frame.
Similarly, from the full winding detection position (33) of the third winding frame body (30) to the second winding frame body other end (22) and from the full winding detection position (23) of the second winding frame body (20). Winding and movement are repeated in sequence with the other end (12) of the first winding frame body, and the winding operation to the main winding frame assembly is completed at the full winding detection position (13) of the first winding frame body (10).

  In the above operation, after the traverse operation in which the first winding frame body (10) fixes the start end, the present invention winds around each winding frame body, for example, 8 times on the forward path and winds 92 times on the return path. In addition, it is possible to perform a winding operation in each of the forward path and the return path so that the total number of windings becomes a predetermined 100 times. According to this winding method, since winding is started from the first winding frame (10) and winding to all the winding frames is completed again with the same winding frame, the winding position of the filamentous material Is substantially the same at the start and end, and the distance over which the filamentous material passes between the winding frame assemblies can be shortened in the preceding and following steps.

Next, as an example of a winding device using the above winding method, a front view of a winding device and a peripheral device of a hollow fiber that is a filamentous material is shown in FIG. 3, and the plan view is shown in FIG. Describe.
A hollow fiber (S) supplied from a spinning device (not shown) is introduced into the winding device (50), and the hollow fiber (S) adjusts the tension of the fiber on the way and detects a missing weight. Via the detector (100).
By using a dancer, when hollow fibers are wound in multiple layers, the tension can be controlled so that the underlying fibers are not crushed by the winding tension. Further, the missing weight detector can detect when a missing weight is generated during winding, and can make the number of windings of the wound hollow fiber constant.

In the present embodiment, a plurality of hollow fibers, for example, 16 fiber bundles, are supplied from the spinning device, and are wound up together in the winding device (50). The winding device (50) includes a pair of winding frame assemblies (51) and (52) at the front and rear, and each winding frame assembly (51) and (52) moves on the rail (53) to the left and right according to work. It is slidable.
A traverse machine (54) which is a winding guide means is arranged on the side of the dancer / missing weight detector (100) of the winding frame assembly (51) (52), and the winding position of the supplied hollow fiber can be freely set. The traverse machine (54) is controlled by a control panel (55).

Each winding frame assembly (51) (52) includes end plates (60) (61) at the outer ends thereof, and the winding frame assembly (51) (51) ( The drive motors (62) and (63) for rotating and driving 52) are arranged.
The drive motors (62) and (63) are placed on the carriages (64) and (65), respectively, and the carriages (64) and (65) travel on the rails (53) of the winding device (50) and move left and right. To slide.

  The reel frame assembly (51) (52) has 12 reel shafts (70) which protrude from the end plates (60) (61) so as to face each other in a circumferential manner, and 4 each on the reel shaft. By the reel partition plates (71), which are individually fitted, the first winding frame body part (72), the second winding frame body part (73), the third winding frame body part (74), and the fourth winding frame. Each body part (75) is formed.

Further, the winding device (50) is provided with a yarn attaching mechanism so that the work of first attaching the yarn to the winding frame assembly (52) can be automated. The yarn attaching mechanism is constituted by an operator first of all with a take-up roll (92), a thread-like material stopper (93) shown in FIG. 9, and a cutter (94).
When threading, an operator first places a thread on the take-up roll (92), and the yarn end is taken into the lower box (95) as the take-up roll (92) rotates.

The thread is passing through the thread stopper (93) and the cutter (94). The thread-like material stopper (93) includes a cylinder part (93b) for moving the locking member (93a) up and down, and clamps the thread-like material between the locking base (93c) and the locking member (93a) when threading. Stop.
On the other hand, immediately after being stopped, the cutter (94) drives the cylinder portion (94a) and cuts the filamentous material with the cutting blade (94b) to be the starting end of winding.
With this operation, in this embodiment, the yarn is automatically attached to the winding frame. Furthermore, during automatic threading, the thread can be threaded in a continuously running state by rotating the reel body simultaneously with stopping and cutting of the thread. Also, some slack that occurs when threading is absorbed by the dancer.

Then, as shown in FIG. 4, at the time of winding, the winding frame assembly is slid toward the traverse machine (54), and the traverse operation according to the present invention is performed by the traverse machine (54).

With the rotation of the ball screw shaft (81), the traverse guide (80) is displaced in parallel with the rotation axis of the winding body, and the position information is detected by the sensor (87). The position information is transmitted to the control panel (55), and a control signal from the control panel (55) controls the AC servo motor (86) to execute the traverse operation.

  At this time, as the traverse operation, in addition to the operation shown in FIG. 1, the second winding frame body (20) and the third winding frame body (30) are first moved to the right end in the same manner as the first winding frame body (10). An operation may be performed in which the yarn is wound or laid and then locked, and the control software can be simplified by reducing the types of operations in this way.

Further, the traverse speed can be easily changed by changing the rotational speed of the AC servo motor (86).
For example, when the hollow fibers are stacked and wound while being aligned at a constant winding width, for example, 120 mm in the present embodiment, the winding is set to 2 to 4 mm / sec. When moving the hollow fiber to the part, 10 to 120 mm / second, when moving between the respective reels, or when moving between the reel assemblies described later, 400 to 750 mm / s, It can be moved faster.

When the winding number detector (not shown) that detects the number of turns in conjunction with the drive motors (62) and (63) detects full winding of all the reels, the hollow fiber is moved to the other reel assembly. Then perform the winding operation again.
That is, when the position of the winding frame assembly is described with reference numerals A to D in FIG. 6, when the winding frame assembly (52) is wound up at the position B and becomes full, The winding frame assembly (51) is arranged at the position D in parallel, and the first winding frame body portion of the winding frame assembly (51) from the first winding frame body portion (72) of the winding frame assembly (52). The thread is moved to (72). At this time, the two winding frame assemblies (51) and (52) are rotated synchronously.

  Note that the rotation of the fully wound reel assembly (52) is stopped, but at this time, the rotation is performed at a position where the end of the filament is in front of the upper end of the reel assembly in the winding direction. Control to stop. This is to prevent the end of the filamentous material from dropping due to gravity when the upper end is exceeded, and to prevent the filamentous material from being unwound and the number of turns from being different.

Immediately after the movement, the winding frame assembly (51) fixes the starting end by performing the traverse operation of the present invention, and the fully wound winding assembly (52) grips the hollow fiber on the winding framework. Disconnect.
In order to cut the hollow fiber of the present embodiment every predetermined length with the wound bundle, the winding frame assembly (52) is slid to the left A position, and cutting and taking out operations are performed. As a result, while performing the winding operation in the winding frame assembly (51), the winding assembly (52) is emptied and the winding operation is started again at the position B when the winding assembly (51) is fully wound. can do.
Similarly, the reel assembly (51) can also perform a continuous operation while sliding the position C and the position D.

As shown in FIG. 7, the end plates (60) and (61a) provided with two reel shafts (70) are separated in a fan shape on the end plates (60) and (61) of the present embodiment. At the time of removal, the reel shaft (70) of the portion is positioned on the same circumference as the others, while the diameter of the hollow shaft is reduced by the operation of the cylinder (90) at the time of taking out the hollow fiber, and a part of it is shown in FIG. It constitutes a tension relaxation mechanism that can relieve tension by cutting.
