2. Description of the Related Art As an example of a winding machine, the following false twisting machine is known. The false twisting machine winds a synthetic fiber that has been subjected to a predetermined false twisting process around a paper tube to form a synthetic fiber package, and a cradle that rotatably supports the paper tube with its axis centered left and right. Some are arranged in three upper and lower stages, and are wound while running the yarn upward so as to pass in front of a winding package on the lower side.

FIG. 5 is a schematic view showing a yarn path in such a false twisting machine. As shown in FIG. 5, a traverse guide G for traversing the yarns y1 to y3 running from the lower side to the upper side right and left is provided immediately below each of the packages P1 to P3 at the uppermost, middle and lowermost stages. I have. Further below the traverse guide G, a traverse fulcrum guide K serving as a traverse fulcrum of the yarns y1 to y3 traversed by the traverse guide G is provided so as to be located at the left and right centers of the respective winding packages P1 to P3. Have been.

When a full package is completed by winding a predetermined amount of yarn on a paper tube, or when a half-ball package is generated due to yarn breakage during winding, the winding packages are connected to both ends of the paper tube. It is removed from the supporting cradle and paid out on the front stocker. The winding package on the stocker is taken out from the front side, for example, manually.

[0005]

However, in the conventional false twisting machine as shown in FIG. 5, the traverse fulcrum of the uppermost and middle packages P1 and P2 is lower than the middle and lowermost packages P2 and P3. Since the trajectory of the packages P1 and P2 is
2, P3. That is, since the traverse trajectories of the uppermost and middle packages P1 and P2 are within the removal trajectories of the middle and lowermost packages P2 and P3, when removing the packages P2 and P3 paid out to the stocker from the front, There was a problem that the yarns y1 and y2 to P1 and P2 were in the way and very difficult to take out.

Further, when removing the packages P2 and P3 while removing the disturbing yarns y1 and y2 to the side by hand,
The traverse fulcrums of the packages P1 and P2 are shifted laterally from the left and right centers, so that the tension of the yarns y1 and y2 during winding cannot be maintained properly, and the package P
There is a problem that the winding shape of P1 and P2 is disturbed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a yarn for arranging a plurality of winding weights in multiple stages adjacent to each other in a vertical direction and supplying a yarn to each of the winding weights. In a winding machine in which the road passes vertically through the front surface of the winding weight, the winding package is taken out while maintaining the tension of the yarn being wound at an appropriate value. It is an object of the present invention to provide a winding machine which can be easily operated without being hindered by a yarn on a take-up package.

[0008]

In order to achieve the above object, according to the first aspect of the present invention, a plurality of winding weights are arranged in multiple stages adjacent to each other in a vertical direction, and a yarn is wound on each of these winding weights. In a winding machine in which the yarn path for feeding passes vertically in front of the winding weight, the traverse fulcrum guide of each winding weight is wound above the winding package removal path of the lower winding weight. A yarn path changing guide that bends the yarn path on the upstream side from the traverse fulcrum guide is provided so as to be arranged substantially at the center in the width direction of the package and to prevent interference with the takeout locus. In the present invention, the traverse fulcrum guide is set at the center position in the width direction of the winding package, and the yarn path on the upstream side is bent so that the upper winding weight also lowers the lower tier while winding the package. Acts to allow removal of the winding package. In addition, the distance between the paper tube and the traverse fulcrum required to prevent large fluctuations in the winding tension due to the traversing operation is extended forward instead of extending downward as in the past. Then, the bend only on the upstream side of the traverse fulcrum guide guides the yarn path so as to avoid the winding package take-out trajectory.

According to a second aspect of the present invention, the yarn path changing guide forms a yarn path near the center in the width direction of the winding package which interferes with the take-out path, and the take-up path is located at a position adjacent to the take-up path. It can be switched to the take-out position where the yarn path retracted to the side is formed. According to the present invention, when the winding package is not taken out and the winding package is not taken out, the winding path is passed from the traverse fulcrum guide on the upstream side with less bending so that the winding path is bent more than when the winding package is taken out. Acts to suppress the

According to a third aspect of the present invention, the winding weights are arranged in three upper and lower stages, and the yarn path changing guide moves one of the two yarn paths passing through a lower winding package removal locus. The left side of the takeout locus is retracted to the right side. According to the present invention, the yarn paths for the winding weights in the upper and lower two stages are distributed to the left and right, so that the respective yarn paths do not interfere with each other.

According to a fourth aspect of the present invention, the position of the yarn path change guide when the yarn path is retracted laterally from the take-out locus of the lower winding package is set forward of the traverse fulcrum guide. It is assumed that the change in the bending angle of the yarn path is set and dispersed. According to the present invention, the position of the yarn path changing guide is three-dimensionally deviated from the position of the traverse fulcrum guide, and the bend formed between the yarn traversed at the traverse fulcrum guide and the upstream yarn. Acts to reduce the angle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings, but the present invention is not limited to the embodiments without departing from the spirit of the present invention. In this specification, “front” means the right side of FIG. 1, “rear” means the left side of the figure, “right” means the back side of FIG. 1, “left” means the front side of the figure, and “up” means FIG. Above and below mean the lower side of the figure.

FIG. 1 shows a main body side of a false twisting machine which is an example of a winding machine. On the main body side of the false twisting machine, three winding weights 1 are vertically arranged adjacently in three stages, and a yarn path for supplying a yarn (synthetic yarn) to each of the winding weights 1 is wound. It passes vertically through the front surface of the weight 1. A large number of such upper and lower three-stage winding weights 1 are arranged in parallel in the left-right direction. There is a yarn supply side composed of a creel stand or the like at a position facing the main body side across the work passage, and the yarn continuously supplied from the yarn supply side is wound by each winding weight 1.

Each take-up weight 1 includes a cradle 3 that swings up and down to rotatably support the left and right ends of a paper tube 2, and a friction roller 4 that makes frictional contact with and rotates the paper tube 2. A traverse device 5 for traversing (traversing) the yarn wound around the paper tube 2 in the left-right direction, a dispensing stocker 6 capable of receiving the winding package P from the cradle 3 at the ascending position, and an operating position. The cutter 7 is capable of changing its position between a standby position and cutting the yarn y being wound in the operating position, and a suction mouth 8 for sucking and holding the yarn y cut by the cutter 7. A threading lever 9 for catching the thread y sucked and held by the suction mouth 8 and threading it on the paper tube 2;
Swingable empty paper core stocker 1 that supplies paper core 2 to
0.

The traverse device 5 traverses the yarn y left and right slightly below and slightly forward of the paper tube 2 which contacts the friction roller 4, and is rotated by rotation of a traverse cam having a spiral groove formed on the surface. It has a traverse guide G that can reciprocate in the left-right direction.

The dispensing stocker 6 is constituted by an inclined guide arranged so as to be connected to the front of the cradle 3 at the raised position. When a predetermined amount of yarn y is wound around the paper core 2 to complete the full package P, the running yarn y being wound by the cutter 7 is cut, and the cradle 3 is cut.
Swings to the ascending position and opens left and right, and the full package is paid out to the payout stocker 6. If the yarn is not completely completed but a yarn break occurs in the middle, the half-ball package P is similarly delivered to the delivery stocker 6.

The discharged winding package P rolls forward along the slope up to the front end on the discharging stocker 6, and is immediately or later removed from the front of the machine from the front side by a human or a removing robot. Since the winding package P is dispensed onto the dispensing stocker 6 at a different timing for each stage due to the difference in the winding start timing and the occurrence of thread breakage, when removing the middle package P2 from the middle dispensing stocker 6, The upper package P1 may be being wound. If there is no payout stocker 6, the take-up package P supported by the cradle 3 is taken out of the machine directly from the front side.

When the winding package P is dispensed from the cradle 3, the empty paper tube stocker 10 swings from the front side to mount a new paper tube 2 on the cradle 3. Thereafter, the cradle 3 is lowered to the position where the winding is performed, and at the same time, the yarn hooking lever 9 is operated, the yarn y held by the suction mouth 8 is hooked on the paper tube 2, and the winding is resumed. As described above, the false twisting machine according to the present embodiment is a single-mass-doff type in which each of the winding weights 1 can individually doff.

At the forefront of the take-up weight 1, a pair of right and left mounting frames 11 extending in the vertical direction are provided. The left and right mounting frames 11 are located slightly forward of the winding package P at the front end on the dispensing stocker 6, and are located on the left and right sides of the winding packages P1 to P3 of each stage when viewed from the front side. .

As clearly shown in FIGS. 2 and 3, the mounting frame 11 is provided with a first guide 12 and left and right second guides 13 at predetermined heights. The first guide 12 is located in front of the middle package P2 and on the obliquely lower right side. The left and right second guides 13 are located slightly forward of the lowermost package P3 and laterally obliquely below the left and right. When viewed from the front side, the winding packages P1 to P3 at the forefront on the delivery stocker 6 in each stage are substantially the same as the winding packages P1 to P3 during winding in each stage shown in FIGS. At a matching height.

A horizontal transfer rod (not shown) is passed between the left and right attachment frames 11 at a height slightly below the contact surface between the winding package P being wound and the friction roller 4. A traverse fulcrum guide K is provided at a substantially middle position of the transfer rod so as to be located substantially at the left and right center (approximately the center in the width direction of the winding package P) of the corresponding winding package P. When viewed from the front side, the traverse fulcrum guide K is located below the winding package P on which the yarn y passing through the guide K is wound, and above the lower winding package P. The traverse thread y traversed by the traverse guide G forms a triangular traverse trajectory having the position of the traverse fulcrum guide K at the top.
In addition, it is preferable that the distance from the traverse fulcrum guide K to the traverse guide G be long in order that excessive tension is not applied to the yarn y during winding.

On the right side of the middle package P2 and on the left side of the lowermost package, there are provided pivoting levers 14 which can pivot about left and right horizontal axes. The left and right swing levers 13 are attached to the left and right attachment frames 11, respectively. A thread path changing guide 15 is provided at the tip of the turning lever.
Moves in an arc shape in the vertical plane in the front-rear direction with the turning of. When the swiveling lever 14 is in the downward state, the yarn path changing guide 15 at the end thereof is located immediately near (slightly above) the first guide 12, and immediately the first guide 1
The yarn y can be caught near 2. When the swivel lever 14 is in the upward state, the yarn path changing guide 15 moves the winding package P2 or P3 on the side.
In addition to being located above, it is a position protruding further forward than the first guide 12, the second guide 13, and the traverse fulcrum guide K. When the turning lever 14 is in the upward state as described above, the yarn path changing guide 15 is moved to the traverse fulcrum guide K.
By being located further forward, the bending angle of the yarn y in the traverse fulcrum guide K can be reduced.

The turning lever 14 can be selectively held in an upward state and a downward state. That is, a spring 16 is provided between the turning lever 14 and the mounting frame 11, so that the turning lever 14 is urged downward during normal winding, and is urged upward when turned to some extent. Has become. Instead of this configuration, the turning lever 14 may be turned by a driving means such as a motor.

Regarding the material of each guide, the first guide 12 and the second left and right
The guide 13 is made of alumina (made of ceramic), and is a yarn path changing guide 15 that comes into contact with the running yarn y only when the yarn path is changed.
Is made of iron-plated metal. As described above, the durability of the guide is increased by making the former guide a ceramic having high wear resistance, and the latter guide is made of a metal having a small contact resistance, so that the yarn path can have a large bending angle. It is possible to prevent excessive tension from being applied to the yarn y during winding.

Next, the change of the yarn path will be specifically described by taking as an example a case where the yarn path of the yarn y1 to the uppermost package P1 is changed. First, during normal winding, the yarn path changing guide 15 is at the winding position, and the yarn y1 to the uppermost package P1 is moved between the first guide 12 and the traverse fulcrum guide K of the middle package P2. Passing across the front. That is, the yarn y1 forms a yarn path near the center in the width direction of the middle package P2, and the yarn path interferes with the takeout locus of the middle package P2. At this time, the first
The bending angle of the yarn path at the guide 12 is small, and stable winding can be performed without applying excessive tension to the yarn y1. The take-out locus of the winding package P is
This is a movement locus along which the winding package P moves when being taken out.

When the turning lever 14 turns upward from the state shown in FIG. 2 and the yarn path changing guide 15 is located at the take-out position, the yarn y1 is caught by the yarn path changing guide 15 during the turning, and the yarn path is changed. Be changed. That is, the yarn y1 forms a yarn path retracted to the right side of the removal locus of the middle package P2, and the yarn y1 and the middle package P2 viewed from the front side.
The overlap with is released. At this time, guide 1
The bending angle of the yarn path at 5 becomes larger than the bending angle of the first guide 12 before the change. In this state, the winding package P at the forefront of the dispensing stocker 6 can be easily removed from the front side by, for example, manual operation.

A yarn path changing guide 15 for changing the yarn path of the yarn y2 to the middle package P2 is disposed on the left side of the lowermost package P3, and the yarn path of the yarn y1 to the uppermost package P1 is on the right side. On the other hand, the yarn path of the yarn y2 to the middle package P2 is retracted to the left.

As described above, the yarn path changing guide 1
According to 5, since the yarn path on the upstream side of the traverse fulcrum guide K of the yarn y that is in the way can be changed only when necessary, it is easy to take out the winding package P while maintaining an appropriate winding tension. Can be done.

The yarn path changing guide 15 may be fixedly provided at the take-out position so that the yarn y always passes along the lateral side of the take-out locus of the lower winding package P during the normal winding. However, in this case, in order to prevent the bending angle of the yarn path from becoming large and applying extra tension to the yarn y, it is necessary to take measures such as increasing the vertical distance between the winding packages P at each stage. There is.

[0030]

The present invention is configured as described above.
The following effects are obtained. According to the first aspect of the present invention, the take-up package can be taken out on the front side of the take-up weight, so that the take-up package can be taken out on the back side of the take-up weight in order to avoid interference with the yarn path. The secondary heaters and the like can be arranged collectively at the winding weight row and back to back, and the body layout can be made compact. Moreover, the winding package can be taken out to the front side independently without considering the presence or absence of the supply yarn to the other winding weight. It is possible to perform stable winding with an appropriate tension, as in the related art, without receiving the same. According to the second aspect of the invention, when the winding package is not taken out, the bending of the yarn path on the upstream side from the traverse fulcrum guide is reduced, so that the influence of the bending of the yarn path on the physical properties of the yarn is minimized. it can. That is, the winding package can be taken out to the front side independently without considering the presence or absence of the supply yarn to the other winding weight, and the quality of the winding package can be stabilized. According to the third aspect of the present invention, since the yarn paths are sorted to the left and right and retracted, there is no interference between the yarn paths and a simple configuration can be achieved. According to the invention as set forth in claim 4, in addition to suppressing the winding of the yarn path when the winding package is not taken out, it is possible to suppress the extremely bending of the yarn path also when taking out the winding package, and the winding package can be removed. It is possible to stabilize the quality of the winding package at the winding weight positioned above the winding weight to be taken out.
