Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a turret type spinning winder for winding continuously supplied yarns alternately with two bobbin holders.

[0002]

2. Description of the Related Art Two bobbin holders are rotatably provided on a rotatable turret plate, and several bobbins are inserted into each bobbin holder.
The bobbin holder of the book is arranged such that one of the bobbin holders is arranged at the winding position and the other is arranged at the standby position, and the bobbin located at the winding position is wound around the bobbin. , Start winding the yarn around the empty bobbin that has newly arrived at the winding position. In this way, it is possible to
A revolving type (turret type) take-up winder that winds alternately with a bobbin holder of a book is already known.

By the way, the operation of the yarn when transferring the yarn from the full bobbin to the empty bobbin in the above-described spinning winder will be briefly described as follows. That is, when the bobbin at the winding position is fully wound, the turret plate rotates 180 degrees, and the positions of the two bobbin holders are switched, so that the full bobbin is newly placed at the standby position and the empty bobbin is newly placed at the winding position. However, when each bobbin is located at the new position, the supplied yarn is still connected to the full bobbin which is in the standby position, and the slits of the empty bobbin catch the yarn and start winding, and The transfer of the yarn from the bobbin to the empty bobbin is completed. That is, when the yarn is caught in 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-mentioned spinning winder,
When transferring the yarn from the full bobbin to the empty bobbin, there are the following problems.

That is, the first problem is that in order to prevent the full bobbin from interfering with the yarn passing device or other members described later, the diameter of the full bobbin is inevitably limited to be small. That is, in transferring the yarn from the full bobbin to the empty bobbin, it is necessary that the yarn surely engages 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 route must be within the full bobbin winding width range and travel parallel to the slits of the empty bobbin. Therefore,
Conventionally, a yarn passing device for bending a yarn between an empty bobbin and a full bobbin has been devised. However, in most of the above-described spinning winders, the yarn passing device is fixed to the turret plate or the like and its position is invariable. Therefore, the yarn is wound on the bobbins of the bobbin holders. When the diameter increases, the yarn passing guide becomes an obstacle, and the diameter of the package when the winding of the yarn is finished is limited to a small size.

A second problem is that the full bobbin initially rotates due to affection even when it is in the standby position, and the cut yarn end of the full bobbin hits the patter and the empty bobbin due to the affective rotation. Therefore, the cut yarn end of the full bobbin is wound around the empty bobbin to hinder the winding of the empty bobbin, or the unwound yarn of the full bobbin is unwound.

Therefore, as a conventional technique for dealing with the first problem, there has been proposed a take-up winder in which a cantilevered yarn passing device is vertically moved between two bobbin holders by a rotating operation or the like to secure a space. (Japanese Patent Laid-Open No. 60-1533)
No. 71). Further, as a conventional technique corresponding to the second problem, it is known to provide a rotatable separator that covers the side surface of the full bobbin.

[0008]

In the conventional technique corresponding to the first problem, since the yarn passing device is still located between the two bobbin holders, the full bobbin cannot be increased in thickness. There was a problem. Furthermore, 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 swirl separator is required in addition to the yarn passing device, and the full space is required. There is also a problem that the bobbin cannot be made larger.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to effectively utilize a space between two bobbin holders in a turret type spin winder. The present invention is intended to provide a spin winder that can be used.

[0010]

SUMMARY OF THE INVENTION A spinning winder according to the present invention that achieves the above object has a turret plate that rotatably projects and supports two bobbin holders rotatably provided on a main body frame. It is possible to switch between the standby position and the standby position, and the traveling yarn connected to the full bobbin that has moved to the standby position when the yarn is switched is guided to the formation position of the yarn catching means provided outside the traverse width of the empty bobbin. A yarn guide, a second yarn guide that supports the traveling yarn on the full bobbin between the empty bobbin and the full bobbin, and a separable separator that partitions the space between the empty bobbin and the full bobbin. The second thread guide is provided on the separator.

[0011]

The second thread guide, which is required to support the thread on the full bobbin, is arranged near the full bobbin, but is provided on the movable separator that partitions the space between the empty bobbin and the full bobbin. Thus, the bobbin can be located in the minimum space between the full bobbin and the empty bobbin. Normally, the separator is mounted on a solid member such as an elevating box or body frame so that it can be moved back and forth while being supported at both ends in the longitudinal direction, and the advance position between the bobbin holders is accurate. By providing the guide, the yarn before the yarn transfer is surely supported on the full bobbin.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 schematically show a take-up winder according to the present invention. FIG. 1 is a front view and FIG. 2 is a side view. Further, FIG. 3 is a developed plan view of the turning separator.

First, the basic structure of the take-up winder will be described with reference to FIGS. The machine frame (7), which is the main frame, has a lift box (1) that can be moved up and down and a rotatable turret plate.
(2) is provided. Incidentally, (10) is an operation box (10) provided at the tip of the fixed frame (18).

A touch roller is attached to the lifting box (1).
(3), the traverse device (4), and the thread shifting guide (5) are respectively supported, and the touch roller (3) is always in pressure contact with the thread layer of the bobbin (B) at the winding position described later. , The bobbin (B) is rotationally driven counterclockwise in FIG. Further, the traverse device (4) is provided with a traverse guide (6), and the traverse guide (6) engages the yarn (Y) and travels in the traverse range to traverse the yarn (Y). ing.

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

The turret plate (2) can be rotated about a rotary shaft (14) by a rotation driving device (not shown), and two bobbin holders (15) and (16) can be freely rotated on the turret plate (2). The bobbin holders (15) (16)
Several bobbins (B) each having a slit (17) as a thread catching means at one end are inserted (two in the figure), and one bobbin holder (15) is at the winding position a. The other bobbin holder (16) is located at the standby position b. The turret plate (2) rotates 180 degrees when the bobbin (B) at the winding position a is fully wound with the thread (Y) 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. 1 and 2 show the state in which the yarn (Y) is transferred, so that the bobbin (B) with full winding 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) moved to the standby position b when the yarn is switched to the slit (17) position of the empty bobbin (B). Acts as a guide to.

Next, a yarn passing device which is an essential part of the present invention,
The structures of the swing arm and the swing separator will be described. The yarn passing 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 as many claws (23) as there are bobbins (B) and can slide to the position of the chain double-dashed line through the elongated hole (24). Normally, the spring (25) is in the right fixed position, but at the time of operation in Fig. 2, the cylinder (26) provided on the turret plate (2) side pushes it to the left fixed position, and the upstream thread The slit (17) catches the yarn (Y) in cooperation with the guide (5) for rewinding and cutting.

As shown in FIG. 3, the fixed guide (22) has a claw (27) facing the claw (23). In the operating position of FIG. 2, the full bobbin (B) moves the thread (Y). The yarn path is regulated so that it will not fall. As described above, the slide guide (21) and the fixed guide (22) of the yarn passing device (20) prevent the yarn path to the full bobbin (B) from being displaced and slit the traveling yarn (Y) into the slit (17).
It operates so as to be captured by. That is, the fixed guide (22) functions as a second yarn guide that supports the traveling yarn (Y) on the full bobbin (B). In addition, slide guide
(21) cooperates with the above-mentioned thread shifting guide (5) to move the running thread connected to the full bobbin (B) moved to the standby position b at the time of thread switching, to the slit (17) of the empty bobbin (B). It functions as an auxiliary first guide for guiding to the position.

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

Next, the turning separator (30) to which the yarn passing device (20) is attached will be described. As shown in FIG. 1, the swirling separator (30) includes a first swirling plate (31) having a yarn passing device (20) at its tip, and a fulcrum (32) at the lifting box (1). A second swivel plate (33) flexibly connected to the (31), and a side link flexibly connected to the first swivel plate (31) having a fulcrum (34) on the lifting box (1). It consists of (35). And side link
A cylinder (36) for turning the (35) makes it possible to turn between a standby position indicated by a two-dot chain line and an operating position indicated by a solid line.

The structures of the first and second swivel plates (31) (33) and the side links (35) will be described with reference to FIG. The first swivel plate (31) has a thread passing device at the tip.
It is a plate in which (20) is fixed, and also serves as an arm and a partition plate. It also has a boss (37) at the left end and a side link (3
It is flexibly connected with 5). Second swivel plate (33)
Holds the first swivel plate (31) flexibly 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 swivel plate
(33) also doubles 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 lift box (1) with a pin (40) to form a fulcrum (34). Therefore, the first
The swivel plate (31) and the second swivel plate (33) are hinged (38)
(38) and pins (39) and (39) make it possible to rotate both sides.

In this way, the two-fulcrum and three-link structure is adopted so that the turning separator (30) fits within the width of the machine frame (7) which is the main frame at the standby position as shown in FIG. Is. If the machine frame (7), which is the main frame, has room, install an L-shaped arm with the thread passing device (20) fixedly attached to the tip.
It may have a structure of turning at a fulcrum. This swivel separator (30) has partition plates (31) (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 tip of the first separator to support the traveling yarn (Y) on the full bobbin (B).

The turning plate (41) is a turning separator (30).
Is located on the opposite side of the full bobbin and has a size that covers the entire width direction of the full bobbin and the half side surface (the right side in the first illustration), and is pinned by the boss (42) below the machine frame (7) which is the main frame. It is stopped and can rotate freely. Normally, it is at the standby position indicated by the chain double-dashed line, but at the operating position, the yarn passing device (20) and the tip of the turning plate (41) face each other as shown by the solid line. That is, the yarn (Y) passes between the two and is closed to the extent that there is no hindrance to 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 swirl plate (41), and the left side of FIG. 1 is completely partitioned by the swirl separator (30). That is, this swirl plate functions as a second separator that cooperates with the above-described first separator (swirl separator (30)).

Next, the operation of the take-up winder having the above structure will be described with reference to FIG. FIG. 4A shows the state immediately before the full bobbin (B) is reached. 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. Then, when the full bobbin (B) is reached, 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 in pressure contact with the empty bobbin (B), but the thread (Y) passes through the empty bobbin (B) and is wound around the full bobbin (B).

Next, the thread shifting guide (5) described with reference to FIG.
The swirling separator (30) swivels to move the yarn passing device (20) to the operating position before the swiveling separator (41) also moves to the operating position. Then, after the state of FIG.
The thread shifting guide (5) and the thread passing device (20) are activated and the empty bobbin
Transfer the yarn (Y) to (B). At this time, full bobbin
Since (B) keeps rotating, the yarn end (43) is swung around, but it is partitioned from the empty bobbin (B) by the partition plate of the swirling separator (30) and the swirling separator (41). After the full bobbin (B) has stopped rotating, the swivel separator (30) and the swivel separator (41) return to the standby position, and the full bobbin (B)
Is taken out, and the empty bobbin (B) is inserted into the state shown in FIG. 4 (d). Then, the yarn (Y) is wound around the empty bobbin (B) that comes into contact with the touch roller (3), and the state shown in FIG. 4 (a) is restored. Then, as shown in the drawing, the swivel separator (30) ascends together with the lifting box (1), so that it does not interfere with the bobbin (B) even in the standby position.

Particularly, when the swivel separator (30) which can move back and forth is advanced to the end so as to scoop the lower side of the empty bobbin (B), the maximum diameter of the full bobbin (B) can be increased and the bobbin holder (15). ) (16) It is possible to increase the diameter of the full bobbin by maximizing the distance between them. Therefore, it is possible to further increase the diameter of the full bobbin (B) as compared with the case where the separator function and the function of supporting the traveling yarn on the full bobbin (B) are separately provided. Further, when the fixed guide 22 is positioned at a short distance between the full bobbin (B) and the empty bobbin (B), the guide accuracy is improved, and the crossover at the time of switching can be prevented. In addition, the turning separator (3
(0) is structured so that it can be moved back and forth from the lifting box (1) that moves up and down with respect to the main body frame (7) with high precision by means of both-sided support at both ends in the longitudinal direction. The guide accuracy is increased due to the synergistic effect with the narrow distance.

[0027]

The spinning winder of the present invention is provided with a separable separator for partitioning the space between the empty bobbin and the full bobbin, and the separator for supporting the running yarn before switching on the full bobbin. Since the second thread guide is provided, the space between the empty bobbin and the full bobbin can be made narrower than the case where the second thread guide is provided separately from the separator so as to be movable back and forth. As a result, the space between the two bobbin holders in the turret type spin winder can be utilized to the maximum, and a large full bobbin can be formed. A large diameter can be achieved. At the same time, the separable separator that separates the space between the empty bobbin and the full bobbin also prevents the winding end of the full bobbin from being cut into the empty bobbin when the traveling yarn is switched from the full bobbin to the empty bobbin. it can. Further, since the second yarn guide can be positioned with high precision in a narrow space between the empty bobbin and the full bobbin, the traveling yarn reaching the full bobbin can be supported with high precision, and the traverse drop at the time of switching is performed. Can be reduced.
