DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a turret type take-up winder in which a continuously supplied yarn is alternately wound by two bobbin holders.

[0002]

2. Description of the Related Art Two bobbin holders are rotatably protruded from a rotatable turret plate, and several bobbins are inserted into each of the bobbin holders.
One of the bobbin holders is arranged at a winding position and the other at a standby position, and the bobbin located at the winding position winds the yarn, and rotates the turret plate 180 degrees every time the bobbin is fully wound. Then, the winding of the yarn on the empty bobbin newly at the winding position is started. In this way, the continuously supplied yarn is
A revolving type (turret type) spinning winder in which winding is alternately performed by a bobbin holder is already known.

[0003] The operation of the yarn winding machine when the yarn is transferred from a full bobbin to an empty bobbin is briefly described as follows. That is, when the bobbin at the winding position becomes full, the turret plate rotates by 180 degrees, the positions of the two bobbin holders are switched, the full bobbin is at the standby position, and the empty bobbin is newly positioned at the winding position. However, when each bobbin is located at the new position, the supplied yarn is still connected to the full bobbin at the standby position, and the yarn is caught by the slit of the empty bobbin and winding is started. The transfer of the yarn from the bobbin to the empty bobbin is completed. That is, at the time when the yarn is captured by the slit outside the traverse range of the empty bobbin, the yarn connected to the full bobbin is cut by the tension of the yarn due to the rotation of the empty bobbin, and is newly wound on the empty bobbin. Go.

However, in the above-described spinning winder,
When transferring yarn from a full bobbin to an empty bobbin, there are the following problems.

That is, the first problem is that the diameter of the full bobbin is limited to a small diameter in order to prevent the full bobbin from being interfered by a yarn transfer device or other members described later. In other words, in transferring the yarn from the full bobbin to the empty bobbin, it is necessary that the yarn is securely engaged with the slit of the empty bobbin, and that the yarn does not come off from the end surface of the full bobbin. The travel path must be within the winding width of the full bobbin and run parallel to the slit of the empty bobbin. Therefore,
Conventionally, a yarn transfer device that bends a yarn between an empty bobbin and a full bobbin has been devised. However, in the above-described spinning winder, in most cases, the yarn transfer device is fixed to a turret plate or the like, and its position is invariable. Therefore, the yarn is wound around the bobbin in each bobbin holder and the yarn layer is formed. When the diameter is increased, the yarn passing guide is in the way, and the diameter of the package when the winding of the yarn is completed is limited to a small diameter.

A second problem is that even when the full bobbin is in the standby position, the bobbin is initially rotated by affection, and the cut end of the full bobbin hits the patter and the empty bobbin due to the emotional rotation. For this purpose, the cut yarn end of the full bobbin is wound around the empty bobbin to hinder winding of the empty bobbin, or the yarn of the full bobbin that has been wound is unwound.

Therefore, as a conventional technique corresponding to the first problem, there has been proposed a spinning winder which secures a space by moving a cantilevered yarn transfer device up and down between two bobbin holders by rotating operation or the like. (Japanese Patent Laid-Open No. 60-1533)
No. 71). In addition, as a conventional technique corresponding to the second problem, it is known to provide a swiveling swivel separator that covers a side surface of a full bobbin.

[0008]

In the prior art corresponding to the first problem, the full bobbin cannot be increased for the thickness thereof because the yarn transfer device is still located between the two bobbin holders. There was a problem. Further, when the swivel separator is advanced between the two bobbin holders as in the conventional technique corresponding to the second problem, a space for securing the advance of the swivel separator is required in addition to the yarn transfer device, and the There was also a problem that the bobbin could not be further enlarged.

SUMMARY OF THE INVENTION The present invention has been made in view of such problems of the prior art, and has as its object to effectively utilize the space between two bobbin holders in a turret type winder. The purpose of the present invention is to provide a spinning winder that can be used.

The bobbin (B) is driven to rotate counterclockwise in FIG. The traverse device (4) is provided with a traverse guide (6). The traverse guide (6) engages with the yarn (Y) and travels in the traverse range to traverse the yarn (Y). ing.

Further, when the position of the full bobbin (B) and the position of the empty bobbin (B) are switched upstream of the traverse device (4) and the yarn is transferred, the engagement of the yarn (Y) with the traverse guide (6) is performed. And a yarn pulling guide (5) for moving the yarn (Y) out of the traverse range. The thread pulling guide (5) is shown in FIG.
On the plate (9) which slides along the guide rod (8) as shown in the figure (the number corresponding to the number of bobbins is 2 in the figure).
The plate (9) is fixed to a piston rod (12) of a cylinder (11), and the operation of the cylinder (11) causes the yarn pulling guide (5) to move to a position indicated by a two-dot chain line (FIG. 2). 13)
Move up to.

The turret plate (2) is rotatable about a rotary shaft (14) by a rotary drive (not shown), and two bobbin holders (15) and (16) are rotatable on the turret plate (2), respectively. And each bobbin holder (15) (16)
, Bobbins (B) each having a slit (17) formed at one end thereof as a yarn catching means are respectively inserted (two in the figure), and one bobbin holder (15) is placed at a winding position a. The other bobbin holder (16) is located at the standby position b. The turret plate (2) rotates 180 degrees when the yarn (Y) is fully wound on the bobbin (B) at the winding position a, and switches the positions of the bobbin holders (15) and (16) to the winding position a. Transfer the thread (Y) from the full bobbin (B) to the newly located empty bobbin (B) and continue winding. FIGS. 1 and 2 show a state in which the yarn (Y) is transferred, so that the full bobbin (B) is supported by the bobbin holder (16) at the standby position b. That is, the above-described yarn pulling guide (5) guides the traveling yarn connected to the full bobbin (B) which has moved to the standby position b at the time of yarn switching to the position of the slit (17) of the empty bobbin (B). Serves as a guide for

Next, a yarn transfer device which is a main part of the present invention,
The structure of the swing arm and the swing separator will be described. The yarn transfer device (20) has a structure in which a slide guide (21) and a fixed guide (22) are arranged vertically. As shown in FIG. 3, the slide guide (21) has a number of claws (23) corresponding to the number of bobbins (B), and can be slid to the position indicated by the two-dot chain line by the elongated hole (24). Normally, the spring (25) is in the right position by the spring (25), but in the operation of FIG. 2, it is pushed by the cylinder (26) provided on the turret plate (2) side to the left position, and the upstream yarn is moved. The yarn (Y) is captured by the slit (17) in cooperation with the shifting guide (5) to perform rewinding and cutting.

As shown in FIG. 3, the fixed guide (22) has a claw (27) facing the claw (23). In the operation position of FIG. 2, the thread (Y) is discharged from the full bobbin (B). The yarn path is regulated so that it does not fall off. As described above, the slide guide (21) and the fixed guide (22) of the yarn transfer device (20) are arranged so that the yarn path to the full bobbin (B) does not shift, and the traveling yarn (Y) is slit (17).
It operates so as to be captured. That is, the fixed guide (22) functions as a second yarn guide for supporting the running yarn (Y) on the full bobbin (B). In addition, slide guide
(21) cooperates with the above-described yarn pulling guide (5) to cut the running yarn connected to the full bobbin (B), which has moved to the standby position b at the time of yarn switching, into the slit (17) of the empty bobbin (B). It functions as an auxiliary first guide for guiding to a position.

By the cylinder (26) provided on the turret plate (2) side, the yarn transfer device (20) does not need to have a driving portion, and the width of the revolving separator (30) described below is reduced. As a result, the overall weight can be reduced.

Next, the revolving separator (30) for mounting the yarn transfer device (20) will be described. As shown in FIG. 1, the revolving separator (30) has a first revolving plate (31) provided with a thread transfer device (20) at the tip, a first revolving plate (31) having a fulcrum (32) in a lifting box (1). A second pivot plate (33) flexibly connected to the first pivot plate (31), the side link having a fulcrum (34) in the lifting box (1) and being flexibly connected to the first pivot plate (31); (35). And the side link
The cylinder (36) for turning (35) can be turned between the standby position indicated by the two-dot chain line and the operating position indicated by the solid line.

The structure of the first and second pivot plates 31 and 33 and the side link 35 will be described with reference to FIG. The first swivel plate (31) has a thread transfer device at the tip.
(20) is a fixed plate, which also serves as an arm and a partition plate. It also has a boss (37) on the left end and a side link (3
5) and bendably connected. Second swivel plate (33)
The first pivot plate (31) is flexibly held by a hinge (38), and is flexibly attached to the lifting box (1) by a pin (39) to form a fulcrum (32). Also, the second turning plate
(33) also serves as an arm and a partition plate. The side link (35) is provided at the left end that does not interfere with the touch roller (3), and is flexibly attached to the lifting box (1) with a pin (40) to form a fulcrum (34). Therefore, the first
The pivot plate (31) and the second pivot plate (33) are hinged (38)
(38) and the pins (39) and (39) enable the swing of the two-sided support.

The two fulcrums and three links structure are used in this way, as shown in FIG. 1, so that the revolving separator (30) can fit within the width of the machine frame (7) as the main body frame at the standby position. It is. If the machine frame (7), which is the main body frame, has room, an L-shaped arm with a thread transfer device (20) fixed at the end is provided.
It may have a structure of turning around a fulcrum. The revolving separator (30) has partition plates (31) and (33), and is provided between the empty bobbin (B) at the upper winding position a and the full bobbin (B) at the lower standby position. And functions as a first separator that covers the left side of the left and right. A second yarn guide is provided at the end of the first separator, and supports the traveling yarn (Y) on the full bobbin (B).

The swivel plate (41) includes a swivel separator (30).
And is large enough to cover the entire width direction and half of the full bobbin (the right side in FIG. 1), and is pinned by a boss (42) below the machine frame (7), which is the main body frame. Stopped and can be turned freely. Normally, it is at the standby position indicated by the two-dot chain line, but at the operating position, the leading end of the turning plate (41) faces the thread transfer device (20) as shown by the solid line. In other words, the space between the two is closed to the extent that the yarn (Y) passes and does not hinder the yarn passing. Therefore, between the full bobbin (B) and the empty bobbin (B),
The right side of FIG. 1 is completely partitioned by the revolving plate (41), and the left side of FIG. 1 is completely partitioned by the revolving separator (30). That is, the swirl plate functions as a second separator cooperating with the above-described first separator (swirl separator (30)).

Next, the operation of the spinning winder having the above-described structure will be described with reference to FIG. FIG. 4A shows a state immediately before the bobbin (B) becomes full. Since there is nothing in the space "S" between the full bobbin (B) and the empty bobbin (B), the full bobbin (B) can be made larger than before. When the bobbin (B) is full, the turret plate (2) rotates clockwise, and at the same time, the elevating box (1) also descends to the state shown in FIG. 4 (b). In this state, the touch roller (3) is pressed against the empty bobbin (B), but the thread (Y) is wound around the full bobbin (B) through the empty bobbin (B).

Next, the yarn pulling guide (5) described with reference to FIG.
Prior to the operation, the swivel separator (30) is swiveled to set the thread transfer device (20) to the operating position and the swivel separator (41) to the operating position. Then, after the state shown in FIG.
The empty bobbin is activated by the operation of the yarn guide (5) and the yarn transfer device (20).
Transfer the thread (Y) to (B). At this time, full bobbin
In (B), since the rotation is maintained, the yarn end (43) is swung, but is separated from the empty bobbin (B) by the partition plate of the revolving separator (30) and the revolving separator (41). Then, after the full bobbin (B) stops rotating, the revolving separator (30) and the revolving separator (41) return to the standby position, and the full bobbin (B)
Is taken out, the empty bobbin (B) is inserted and the state shown in FIG. Then, the thread (Y) is wound around the empty bobbin (B) in contact with the touch roller (3), and the state returns to the state shown in FIG. Then, as shown in the figure, the revolving separator (30) rises together with the lifting box (1), so that it does not obstruct the bobbin (B) even in the standby position.

In particular, when the revolvable revolving separator (30) is made to extend just below the empty bobbin (B), the maximum diameter of the full bobbin (B) can be increased and the bobbin holder (15) can be enlarged. The diameter of the full bobbin can be increased by maximizing the distance between (16) and (16). Therefore, the diameter of the full bobbin (B) can be further increased as compared with a case where a separator function and a function of supporting the traveling yarn on the full bobbin (B) are separately provided. Further, when the fixed guide 22 is located at a short distance between the full bobbin (B) and the empty bobbin (B), the guide accuracy is improved, and it is possible to prevent the traversing during switching. In addition, swivel separator (3
(0) from the lifting box (1), which moves up and down with respect to the body frame (7) with high precision, is provided so that it can move forward and backward by supporting both ends in the longitudinal direction. Guide accuracy is increased by synergy with a small distance.
