Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for sequentially winding filaments, in particular fishing fishing lines, on a large number of spools arranged axially adjacent to each other.

[0002]

2. Description of the Related Art Heretofore, in many cases, a fishing tackle trader rewinds Tegs supplied from a fiber maker by winding them on a large spool and then remarketing them into a commercially available spool. This commercially available spool has, for example, the following configuration.

A disk-shaped end plate 3 having a keyhole-shaped central hole 2 is integrally formed at one end of a short cylindrical winding core 1 and an annular end plate 4 is integrally formed at the other end. The connecting cylinder 5 having an outer diameter substantially equal to the inner diameter of the winding core 1 extends outward. The end plates 3 and 4 have notches 6 and 7 at the same position on the outer circumference.
Have respectively. Further, a ridge 8 is projectingly provided at the same position as the notches 6 and 7 on the inner surface of the winding core portion 1, and a notch 9 is formed at the same position as the notches 6 and 7 of the coupling cylinder 5.

Therefore, by pushing the connecting cylinder 5 into the winding core portion 1 of the adjacent spool so that the slit 9 of the connecting cylinder 5 coincides with the ridge 8 of the adjacent spool, a large number of spools are centered. They can be joined axially, with the notches 6, 7 of each spool all being aligned and the keyhole-shaped central holes 2 all being in the same direction.

The spool combination described above is mounted on a winding device and rotated by a drive device. The Tegus fed from the large spool is supplied to the spool via a yarn length meter and a feed mechanism. The feeding mechanism feeds the guts from the guide to the spool while reciprocating the guide at the tip by the width of each spool. When the length of the guts detected by the yarn length meter reaches a predetermined length, the feeding mechanism moves to the position of the adjacent spool and a new winding starts. At that time, the Tegus moves to the adjacent spool at the positions of the notches 6 and 7.

[0006]

In a spool in which winding is newly started, the starting point of winding does not always come to the end of the spool, but it often comes to an intermediate unspecified position. The starting end portion of the crossing reaches the winding start point from the notches 6 and 7 and reaches the winding start point, where it comes into contact with the winding core 1 and the winding starts there.

When the aligned winding moves from the starting point toward the front reel in accordance with the reciprocating movement of the leading end guide of the feed mechanism, the newly wound Tegs has the above-mentioned floating starting end portion to the winding core 1. In order to suppress it, a strong distortion is caused at this starting point. This distortion causes entanglement and cutting when using a long Tegs that spans multiple spools.

Further, when the newly wound Tegu rides on the starting end portion floating in the air, the aligned winding is often disturbed. Since yarns such as Tegus tend to ride on a thick portion when winding, once the aligned winding is disturbed, the disorder becomes more and more significant as the winding progresses.

It is an object of the present invention to prevent the occurrence of distortion at the starting end portion by starting the aligned winding from the end of the spool and to obtain the correct aligned winding.

[0010]

According to the present invention, a spool on which a yarn is to be wound has flange-like end plates at both ends of a short cylindrical winding core portion, like a conventional spool. Each end plate has a notch in the peripheral portion. A plurality of such spools are coupled in the axial direction to form a spool coupling body, in which case the notches are aligned on a straight line parallel to the central axis.

A spool winding device according to the present invention comprises a first drive device for supporting the above-mentioned spool combination body and rotationally driving it in the yarn winding direction, and a large spool on which a long yarn is wound. The yarn supply source having, the guide means for guiding the yarns fed from the supply source, and the width of the winding core portion of each spool received from the guide means while performing reciprocating motion of a corresponding distance. It is composed of a feeding device for feeding the kind to one of the spools from a guide at the tip and a control circuit for controlling the operation of the above-mentioned respective parts.

The first driving device is provided with a spool rotation position detecting means, the feed mechanism is provided with a spool end plate position detecting means, and the guiding means or the feeding mechanism is provided. A means for measuring the length of the thread wound on the spool is attached. In addition, if necessary, the feed mechanism or the guide means is provided with a means for detecting the tension of the yarns passing therethrough.

The operation of each section under the control of the control circuit is as follows. When it is detected by the length measuring means that the length of the yarn wound on the first spool has reached a certain length due to the rotation by the first driving device and the reciprocating supply by the feeding mechanism. The first drive device is stopped at the position detected by the rotational position detection means. At this stop position, the notch of the end plate is located at the position of the thread wound on the spool.

Next, the second drive device operates to move the feeding mechanism to the position of the second spool adjacent to the first spool. Then, the first drive device operates,
Spool within 180 °, preferably 45 ° to 135
Rotate in the winding direction only by °.

Then, the second drive device operates again to move the feeding mechanism so that the guide comes to the end on the first spool side of the core portion of the second spool. This position is detected by the spool end plate position detecting means.

Rotation of the spool by the first drive device,
The reciprocating motion of the feeding mechanism by the second drive device starting at the end of the winding core starts the overlapping winding of the yarns on the second spool. By repeating the above operation, the yarns are wound around the spool forming the combined body in order from the end of the spool by a predetermined length.

[0017]

In the control circuit, the spool diameter, the winding width, the thread diameter, the winding length, the number of spools, the spool diameter in the supply source, and the like are set, and the spool coupling body is supported by the first drive unit, and the first end at one end is set. Starting winding from the spool. As for winding, the yarns are supplied to the spool from the guide of the feeding mechanism at a speed calculated from the rotation speed of the spool and the set thread diameter, and at a speed corresponding to the set winding width, so the layers are arranged in an orderly manner. The winding is done.

When the winding amount reaches the set yarn length, the spool stops at the rotational position detected by the rotational position detecting means,
At this time, the notch of the spool end plate coincides with the position of the thread extending from the guide to the spool. Next, the feeding mechanism moves by the set winding width, the guide moves to the position of the second spool, and at this time, the thread passes through the notch of the end plate and moves to the second position.
Move to the spool position of.

Next, when the spool is rotated by an angle of 180 ° or less, the threads are securely caught in the notches of the end plate,
In addition, it is in a state of lightly contacting the core or passing through the air straight from the guide to the notch. When the feeding mechanism is returned to the position where the end plate on the first spool side is detected by the detecting means, the yarns from the guide toward the winding core portion come to the starting end position of the winding core portion.

Therefore, when the spool is restarted while reciprocating the feed mechanism with this position as the starting end,
The winding of the yarns starts from the end of the winding core on the side of the first spool, and the winding is performed in an orderly manner. Therefore, the phenomenon in which tension is applied to the starting end portion of the thread on the second spool to distort the same does not occur.
