[Industrial applications]
The present invention relates to a yarn winding machine that winds a yarn on a plurality of bobbin holders at the same time. More specifically, the present invention provides a turret table rotatably in a unit case, rotatably supports a plurality of bobbin holders for mounting a bobbin for winding a yarn on the turret table, and winding the bobbin holder on one bobbin holder. When the amount of the thread reaches a predetermined amount, the bobbin is switched to the bobbin mounted on the other bobbin holder, and a plurality of revolving type automatic winding machines configured to wind the thread are arranged side by side, and the thread is simultaneously moved to the plurality of bobbin holders. The present invention relates to a yarn winding machine adapted to be wound.
[0002]
[Prior art]
Generally, when a yarn spun from a spinneret of a spinning machine is continuously wound, a turret table rotatably mounted on a unit case and a turret table rotatably supported on the turret table, for winding the yarn. Two bobbin holders for mounting bobbins, a movable frame vertically moving up and down, a contact pressure roller rotatably attached to the movable frame, and an upstream side of the contact pressure roller as viewed in the yarn thread direction. A revolving-type yarn winding machine constituted by a traverse device located is used.
[0003]
As a configuration of such a conventional yarn winding machine, there is a structure in which two winding machines are arranged adjacent to each other, the yarn is separated from an upstream feed roller, and the yarn is wound on the two winding machines. Was.
[0004]
As another conventional technique, Patent Document 1 (Japanese Patent Application Laid-Open No. 1-267270) discloses a technique in which a plurality of turret tables are vertically arranged in one machine frame.
[0005]
As still another conventional technique, Patent Document 2 (Japanese Patent Application Laid-Open No. 2002-515388) discloses that two turret tables are vertically arranged in one machine frame, and units constituted by these are symmetrically arranged. Is disclosed.
[0006]
In recent years, there has been a tendency to increase the number of ends of a yarn winding machine in order to increase the amount of production. In this case, it is required to improve the space efficiency per production amount, reduce the equipment cost, improve the threading efficiency, and improve the winding shape.
[0007]
In response to this request, the conventional device described first has a configuration in which two winders are arranged in parallel, so that the interval between the yarns entering the two winders increases. The angle α between the two yarns coming out of the feed roller becomes large. As a result, there has been a problem that the contact angle between the yarn and the guide G is increased, the frictional resistance is increased, and the yarn is fluffed.
[0008]
As a countermeasure, if the contact angle between the yarn and the guide G is reduced, the position of the feed roller is increased, and there is a problem that operability is deteriorated.
[0009]
In the conventional apparatus disclosed in Patent Document 1, since a plurality of turret tables are arranged vertically (up and down), the height of the machine is increased and operability is significantly deteriorated.
[0010]
Further, in the conventional device disclosed in Patent Document 2, at the time of the first yarn hooking, a plurality of yarns are sucked by the yarn suction device while passing through the traverse fulcrum guide through the traverse fulcrum guide, and the contact pressure disposed downstream of the traverse device. Since the thread is hung on the bobbin mounted on the bobbin holder rotating in contact with the roller, the following problem occurs.
[0011]
The winding device is disposed vertically and symmetrically left and right. For this reason, at the time of yarn winding, in order to avoid interference between the yarn and the winder portion, it is necessary to carry out the yarn winding one by one from the upper or lower winder while sucking a plurality of yarns. Was. As a result, the time required for threading became long, the amount of waste thread increased, and the efficiency became poor.
[0012]
Even when the yarn is hooked on the left and right winding devices, the contact roller and the bobbin holder are in contact in a state where they are lined up in the horizontal direction. However, there was a problem that the threading success rate was reduced.
[0013]
Further, as the contact pressure roller retreats in the horizontal direction as the yarn becomes thicker, the width of the winding machine is increased, and the efficiency of the installation space is significantly deteriorated.
[0014]
In view of the above-mentioned problems associated with the prior art, the present applicant provides a multi-end revolving type automatic winder having good operability, high yarn threading properties, and high space efficiency. For this purpose, Patent Document 3 (Japanese Patent Application No. 2002-33760) has been proposed.
[0015]
In Patent Literature 3, at least two bobbin holders are rotatably mounted on a turret table rotatable about a rotation center, and a contact pressure roller and a traverse device installed on the yarn path upstream with respect to the bobbin holders. In the revolving type automatic winding machine, having a predetermined amount of yarn wound on the bobbin mounted on one bobbin holder, switching the bobbin mounted on the other bobbin holder to wind the yarn, The turret table is disposed on both sides of the yarn path, and the rotation directions of one turret table and the other turret table are opposite to each other, and a contact pressure roller provided for one turret table is provided. The rotation directions of the other turret table and the contact pressure roller installed are opposite to each other, and Winder roller and the traverse device is characterized in that located above the center of rotation of the turret table is proposed.
[0016]
Further, the present applicant has proposed Patent Document 4 (Japanese Patent Application No. 2002-239860). In this Patent Document 4, at least two bobbin holders are rotatably mounted on two turret tables, and a contact pressure roller and a traverse device are arranged on the upstream side of each turret table corresponding to the bobbin holders. In the revolving type automatic winding machine, when the yarn wound on the bobbin mounted on the bobbin holder reaches a predetermined amount, the bobbin is switched to the bobbin mounted on the other bobbin holder to wind the yarn. Are arranged with the yarn path interposed therebetween, and the rotation directions of the contact pressure roller provided for one turret table and the contact pressure roller provided for the other turret table are opposite to each other. The rotating direction of one turret table and the other turret table are opposite to each other, and during the winding of the yarn, The center of each of the contact pressure rollers contacting the bobbin holder or the yarn being wound is connected to an imaginary line connecting the centers of the two bobbin holders projecting from the one turret table and the other from the other turret table. A revolving type yarn winding machine characterized in that it is configured to be located between the two bobbin holders provided and an imaginary line connecting the centers of the two bobbin holders, has been proposed.

[Problems to be solved by the invention]
Although the details of the traverse fulcrum guide are not disclosed in the yarn winder of the type disclosed in Patent Document 3 or Patent Document 4 described above, actually, as shown in FIG. At the upstream position of the apparatus, a shaft 51 is provided in parallel with the bobbin holders 4, 5, 4 ', 5', and blocks 52 are mounted movably along the shaft 51. The bobbin holders 4, 5, 4 Bars 53 orthogonal to '5' and '5' are provided. Each bar 53 is provided with traverse fulcrum guides 12 and 12 'so as to separate the yarn fed from upstream.
[0022]
However, in such an apparatus, as shown in FIG. 7B, the block 52 is moved to the work surface side along the shaft 51 when the yarn is hooked, and the yarn is moved to the traverse fulcrum guide 12 arranged on one side of the block 52. Then, it is necessary to move the suction gun SG to thread the traverse fulcrum guides 12 ′ arranged on the opposite side of the block 52. In such a traverse device. Since the suction gun SG is moved while the yarn is being picked up, the yarn comes into contact with the shaft 51 and other members, and the yarn being hooked often breaks.
[0023]
[Means for Solving the Problems]
As a countermeasure, as shown in FIG. 4, a bar is protruded only on one side of the block parallel to the bobbin holder at the upstream position of the traverse device, and the back side of the bar (near the block) and the front side (from the block). It is conceivable to install a plurality of traverse fulcrum guides in parallel with the distant side).
[0024]
That is, according to the present invention, in the yarn winding machine configured to simultaneously wind the yarn on the plurality of bobbin holders, the plurality of traverse fulcrum guides are orthogonal to the axial direction of the bobbin holder at the upstream position of the traverse device. A yarn traversing device is provided, wherein the yarn traversing device is arranged in parallel in a direction in which the yarn is traversed.
[0025]
In the present specification, the “direction orthogonal to the axial direction of the bobbin holder” includes not only a direction forming an angle of 90 ° with the axial direction of the bobbin holder, but also a direction substantially or substantially 90 ° from the axial direction of the bobbin holder. It also includes directions making angles.
[0026]
In such an apparatus, the operation can be performed from one side of the block, and the suction gun does not need to be largely moved. However, it is necessary to alternately thread the traverse fulcrum guides installed in parallel on the back side and the near side of the bar in order from the work surface side (tip end of the bobbin holder). For this reason, the traverse fulcrum guide on the front side may be an obstacle particularly when the yarn is hooked on the traverse fulcrum guide on the back side. In addition, the thread is hooked in a narrow space. For these reasons, it may take a long time to hook the thread, and there is a concern that a large number of thread breaks are likely to occur due to a work error caused by the thread coming into contact with the guide on the near side.
[0027]
As a countermeasure, in the present invention, the plurality of traverse fulcrum guides are arranged in parallel in a direction orthogonal to the axial direction of the bobbin holder during winding of the yarn, and the yarn is wound around the plurality of bobbin holders simultaneously. A yarn traversing device is provided which is adapted to take up the traverse fulcrum guide so that the traverse fulcrum guide can be aligned in the axial direction of the bobbin holder when the yarn is hooked on the traverse fulcrum guide.
[0028]
More specifically, as shown in the embodiment, by providing a link mechanism inside the traverse device and pulling the shaft, the traverse fulcrum guide rotates 90 degrees and is arranged in a line in the axial direction. Is preferred.
[0029]
Furthermore, according to the present invention, there is provided a yarn traversing device in which the plurality of traverse fulcrum guides can approach each other in the axial direction of the bobbin holder when the yarn is hooked on the traverse fulcrum guide.
[0030]
That is, as shown in the embodiment, the traverse device is provided with a slide mechanism, and by further pulling the shaft. It is preferable that the traverse fulcrum guide can be drawn forward.
[0031]

A base 2 is provided at the bottom of the unit case 1 of the winder W, which can take a parallel position (a thread hooking position), to the vicinity of a front (left side in FIG. 2) work space. Disc-shaped turret tables 3, 3 'are provided on the front surface of the unit case 1 so as to be rotatable around its horizontal center axis, and the turret table 3 is rotated clockwise by driving means (not shown) such as a motor. The turret table 3 'is turned counterclockwise in opposite directions.
[0039]
The turret tables 3, 3 'are provided with two bobbin holders 4, 5, 4', 5 'rotatably projecting in a direction perpendicular to the paper surface of FIG. 1 (the paper surface direction of FIG. 2). The bobbin holders 4, 5, 4 ', 5' are connected to a driving device (not shown). At a predetermined speed, the two bobbin holders 4, 5 rotate clockwise, and the other two bobbin holders 4 ', 5 'is adapted to be rotated counterclockwise.

It may be a friction drive type winder as described above.
[0041]
Two slide rails (not shown) are vertically mounted inside the unit case 1, and the lifting frame 8 can be moved up and down along the slide rails by a fluid cylinder (not shown).
[0042]
The lifting frames 8, 8 'are provided with bobbin 6 mounted on the bobbin holders 4, 5, 4', 5 'or contact pressure rollers 9, 9' and a yarn Y which come into contact with a yarn layer formed thereon. 6, a traverse device 10 that traverses in the axial direction is supported. At least one of the contact pressure rollers 9 and 9 ′ is supported on the lift frame 8 in a swingable state independently of the lift frame 8.
[0043]
When the yarn Y is wound around the bobbin 6 mounted on the bobbin holders 4, 5, 4 ', 5', the contact pressure rollers 9, 9 'send the yarn Y to the bobbin 6 and simultaneously move the yarn Y to the bobbin 6 or on the bobbin 6. The formed yarn layer is brought into pressure contact with the package surface to improve the package shape and increase the package hardness.
[0044]
In the embodiment, one traverse device 10 is provided between two contact pressure rollers 9 and 9 '. The traverse device 10 has a cylindrical cam (not shown) rotated by a driving device (not shown), and the traverse guide engaged with the groove of the cam reciprocates left and right to engage with the traverse guide. The yarn Y is traversed in the axial direction of the bobbin 6 within the traverse range.
[0045]
Although a cam type traverse device is employed in the embodiment, a rotary blade type traverse device may be used in the present invention.
[0046]
In the present embodiment, the centers of the contact pressure rollers 9 and 9 ′ in contact with the bobbin holders 4, 5, 4 ′ and 5 ′ are centered on the two bobbin holders 4 and 5 protruding from one turret table 3. And a virtual line segment c 'connecting the centers of the two bobbin holders 4' and 5 'protruding from the other turret table 3'.
[0047]
In the present embodiment, two turret tables are disposed with the yarn path interposed therebetween, and the rotation direction of the contact pressure roller provided for one turret table and the contact pressure roller provided for the other turret table Are opposite to each other, and the rotating directions of the one turret table and the other turret table are opposite to each other. Therefore, the machine width of the entire winder can be reduced. For this reason, the installation space of the winder is reduced, and the space efficiency is improved.
[0048]
Further, when the yarn switching is started, that is, when the rotation of the turret table is started, acceleration is applied to the turret table, and the bobbin holder tends to push up the contact pressure roller due to the acceleration. On the other hand, in the present invention, the contact pressure rollers 9, 9 'are arranged in a special geometric positional relationship with the turret tables 3, 3', that is, in contact with the bobbin holders 4, 5, 4 ', 5'. The center of the contact pressure rollers 9 and 9 'is a virtual line segment c connecting the centers of two bobbin holders 4 and 5 protruding from one turret table 3 and the center 2 protruding from the other turret table 3'. It is located between the bobbin holders 4 'and 5' and a virtual line segment c 'connecting the centers of the bobbin holders 4' and 5 '. With this geometrical arrangement, it is possible to prevent the bobbin holder from pushing up the contact pressure roller due to the acceleration at the start of rotation of the turret tables 3, 3 ', and the bobbin holder can rotate smoothly, There is an advantage that damage due to the centering of the yarn on the package surface layer at the start of table rotation or damage due to contact pressure can be prevented, and the quality of the yarn can be improved.
[0049]
Further, in addition to the above-described geometric arrangement, a vertical line d and an imaginary line connecting the rotation centers of the contact pressure rollers 9, 9 'and the bobbin holders 4, 5 during the winding of the yarn are defined. By setting the angle β to 45 degrees or less, the moving direction of the contact pressure rollers 9 and 9 ′ can be made substantially vertical. For this reason, the width of the winder can be reduced, and the efficiency of the installation space can be improved.
[0050]
Furthermore, the imaginary line segments c and c 'connecting the centers of the two bobbin holders 4, 5, 4' and 5 'are formed in a "C" shape at least at the beginning of the winding of the yarn. That is, by setting the interval between the empty bobbins 4, 4 'smaller than the interval L when the diameter of the full package is mounted and larger than the interval where the full package immediately after switching does not interfere, the machine width is reduced. Can be reduced.
[0051]
Further, as described above, the traverse fulcrum guide moving device 11 is provided substantially in parallel with the bobbin holder above the traverse device, and the traverse fulcrum guide moving device 11 is mounted on the bobbin holders 4, 5, 4 ', 5'.

On the other hand, when the yarn is hung on the bobbin, the yarn moves to the distal end side of the bobbin holder, that is, to the operation side.
[0053]
Further, the lower ends 14a, 14'a of the threading devices 14, 14 'are pivotally attached to the lower part of the center of the unit case 1, and the threading devices 14, 14' are pivoted around the lower ends 14a, 14'a. It is swingable, and is moved by a cylinder (not shown) between a return position (FIG. 1) below the center of the unit case 1 and an operating position (FIG. 4) at the time of initial threading.
[0054]
That is, the threading devices 14, 14 'are provided corresponding to the respective bobbin holders 4, 5 on the winding side, and the threading devices 14, 14' are provided with an initial threading guide 15, 15 '. The threading devices 14 and 14 'are stored in the storage position (FIG. 1) during storage, and are movable from the storage position to the threading position during threading. Here, the storage position is a position between the trajectories a and a 'drawn by the outer diameters of the bobbins mounted on the bobbin holders protruding when the turret tables 3 and 3' rotate. On the other hand, the thread hooking position is located beyond a tangent line b, b 'between the contact rollers 9, 9' and the outer diameter of the bobbin 6 rotating in contact with the contact rollers 9, 9 '. Can be moved in the direction away from each other.

【The invention's effect】
According to the present invention, in a yarn winding machine configured to simultaneously wind yarn on a plurality of bobbin holders, a plurality of traverse fulcrum guides are arranged in a direction orthogonal to an axial direction of the bobbin holder at an upstream position of the traverse device. When the yarn is hooked on the traversing fulcrum guide, it is sufficient to operate from one side of the block, and it is not necessary to largely move the suction gun, thereby improving workability.
[0066]
Further, according to the present invention, a plurality of traverse fulcrum guides are arranged in parallel in a direction orthogonal to the axial direction of the bobbin holder during winding of the yarn, so that the yarn is wound on the plurality of bobbin holders simultaneously. When the yarn is hooked on the traverse fulcrum guide, the bobbin holder can be aligned in the axial direction. Therefore, especially when the yarn is hooked on the traverse fulcrum guide on the back side, the traverse fulcrum guide on the front side does not become an obstacle, and the yarn can be hooked in a sufficiently large space. For these reasons, no time is required for threading, and there is no work error due to the thread coming into contact with the guide on the near side, and the occurrence of thread breakage is significantly reduced.
[0067]
Still further, according to the present invention, there is provided a yarn traversing device in which a plurality of traverse fulcrum guides can approach each other in the axial direction of the bobbin holder when the yarn is hooked on the traverse fulcrum guide. Can be performed more easily.
[0068]
In particular, in the embodiment, since the traverse fulcrum guide is rotated 90 degrees and can be arranged in a line, the traverse fulcrum guide on the front side at the time of threading does not become an obstacle, and it is possible to reduce the threading time and reduce operation errors. It becomes possible.
