[Detailed description of the invention]

[0001]

The present invention relates to an improvement in a yarn winding tube mainly used for winding a synthetic fiber filament yarn.
And a yarn winding package.

[0002]

2. Description of the Related Art Generally, a tube used for winding a synthetic fiber yarn is provided with a yarn catching groove having a V-shaped cross section at the longitudinal end of a cylindrical body formed of laminated paper. Have been.

[0003] The above-mentioned yarn catching groove is formed by an introduction portion having a V-shaped cross section and a catching portion having a narrow groove shape, and the catching portion is provided with a tube for preventing the captured yarn from coming off. The circumferential portion is crushed so that the narrow groove-shaped capturing portion is in close contact.

[0004] In such a tube, there is a problem that the yarn does not bite into the catching portion even when the yarn is run in a state of contact with the introduction portion of the yarn catching groove.

There is also a problem that unless the yarn is moved in a state parallel to the yarn catching groove, the yarn will not bite into the catching portion.

Further, when trying to remove the yarn trapped and wound by the catching portion, the thread is caught in a projection or the like formed by crushing the narrow groove of the catching portion, and becomes fluffy. A part of the thread that has become remains in the supplementary part.

[0007] Therefore, there is a problem that the fluffy thread caught on the projection in the capturing portion at the time of re-use must be removed.

There is another problem that the bunch-wound yarn must be removed so as not to be caught in the yarn catching groove.

Therefore, using a tube in which a thread catching groove is not formed, a joining portion where the tube end surfaces are in contact with each other,
Alternatively, the yarn is captured at the joint where the tube end surface and the end surface of the step portion of the tube tightening spindle abut, and then a tail winding is formed at the circumferential end of the tube, and then the yarn is traversed and wound. Things are going on.

The above-mentioned tube having no thread catching groove is made of a U-shaped groove having a vertical surface and a tube having a U-shaped groove when two tubes are abutted against each other as described in JP-A-51-43411. A shape in which a yarn catching portion to which an end surface is joined is formed, or an inclined surface protruding in a length direction from an outer peripheral edge toward an inner peripheral edge is provided on a tube end surface, and when two tubes are abutted, V is formed by the inclined surface. It has a shape in which a letter-shaped yarn catching portion is formed.

The yarn is guided to the yarn catching portion by a yarn introduction portion which is a U-shaped groove or a V-shaped opening formed by the two tubes, and the yarn has a gap whose inner circumferential direction is reduced. The yarn is held by the catching portion.

The above-mentioned tube has a configuration in which a cylindrical body is formed of laminated paper, and a surface paper is adhered to the outer peripheral surface thereof.

[0013]

If the above-described yarn introduction portion is formed in a U-shaped groove, the captured yarn will
Since the thread does not contact the vertical wall surface of the U-shaped groove, the yarn does not move to the circumferential surface side of the tube due to the frictional force with the vertical wall surface, and the yarn is wound around the U-shaped groove portion.

In order to prevent the thread wound in the U-shaped groove from hanging down during the doffing operation or the carrying operation, the operator must remove the thread and generate a large amount of waste thread. There is a problem of doing.

Further, there is a problem that a yarn moving mechanism for moving the yarn caught in the U-shaped groove to the bunch winding position must be provided in the winding machine.

On the other hand, when the yarn catching portion is formed in a V-shaped groove, the difference between the outer diameter of the tube and the diameter of the bottom of the V-shaped groove in which the yarn is captured is substantially equal to the thickness of the tube. Occurs.

For this reason, by rotating a turret member on which a plurality of tube tightening spindles are rotatably mounted, the spindle which has been fully wound is moved from the winding position to the doffing position, and the spindle which tightens the empty tube is rotated. When the yarn is switched by the turret type winder that moves from the doffing position to the winding position, the peripheral speed of the bottom of the V-shaped groove for catching the yarn is smaller than the peripheral speed of the circumferential surface of the tube. There is a problem that the yarn is not captured in the V-shaped groove because the tension of the yarn is reduced by the thickness dimension and the yarn is lowered.

Further, even when the yarn is captured, the tension of the yarn is reduced, so that the yarn is wound around a roller provided on the upstream side of the turret type winder.

As a result, there is a problem that the success rate of switching the yarn from the fully loaded tube to the empty tube is 10% or less.

When the above-mentioned tube is formed of laminated paper, when the tube is used repeatedly, the surface paper at the end of the tube peels off or bulges.

For this reason, the yarn cannot be introduced into the catching groove, or when the yarn is released, the unwinding tension fluctuates due to contact with the peeled surface paper or the swelled surface paper, or the yarn breaks. There's a problem.

The present invention solves the above-mentioned problems, and can reliably capture the yarn, and can quickly move the captured yarn from the capture position to the bunch winding position. It is an object of the present invention to provide a tube for winding, a yarn winding tube that can be used repeatedly, and a yarn winding package in which long yarn ends do not hang down during doffing and conveying operations and are easy to handle. .

According to a first aspect of the present invention, there is provided a yarn winding tube in which at least one end face of a cylindrical body has an inner peripheral side orthogonal to a longitudinal direction of an axis. A flat surface substantially parallel to the surface in the direction in which the flat surface is formed, and an outer circumferential side from the flat surface is formed so as to be an inclined surface protruding in the axial direction from the outer peripheral edge toward the outer peripheral surface of the flat surface. The ridge connecting the outer peripheral surface of the body is formed in an arc shape with a radius of 2 mm or less.

In the yarn winding tube, the end surface of the cylindrical body is formed to be substantially parallel to the surface in the direction orthogonal to the longitudinal direction of the axis, and one end surface and the outer peripheral surface of the cylindrical body. Is formed so as to have an arc shape having a radius of 2 mm or less, and the ridge connecting the other end surface and the outer peripheral surface of the cylindrical body has an arc shape having a radius larger than the radius of the ridge portion of the end surface. It can also be formed into a shape.

Further, the outer peripheral surface of the conjunction allowed to form a yarn Jomakito package in the direction of the plane substantially parallel to a plane of the end surfaces perpendicular to the axial longitudinal direction as according to claim 4, one end surface and the cylindrical body Is formed so as to form an arc having a radius of 2 mm or less, and the ridge connecting the other end surface and the outer peripheral surface of the cylindrical body has an arc shape having a radius larger than the radius of the ridge of the end surface. A bunch winding, a tail winding, and a wound layer can be sequentially formed to hold the yarn end on the end side of the circumferential surface of the formed tube .

[0028]

According to the yarn winding tube of the present invention, the inner peripheral side of at least one end face of the cylindrical body is formed in a plane substantially parallel to a plane perpendicular to the longitudinal direction of the axis. In addition to forming the outer peripheral side to be an inclined surface,
Since the ridge connecting the inclined surface and the outer peripheral surface of the cylindrical body is formed so as to have an arc shape having a radius of 2 mm or less, the yarn is introduced into the catching portion by the yarn introduction portion formed by the inclined surface. The yarn is guided and captured, and the yarn captured by the rotation of the tube comes into contact with the inclined surface and is quickly moved to the bunch winding position on the circumferential surface.

[0029]

FIG. 1 is a schematic perspective view showing a state in which a yarn winding tube according to the present invention is mounted on a spindle. FIG. 2 shows the shape of a yarn winding tube in a first embodiment in FIG. FIG. 3 is an enlarged view of a portion I in FIG. 1, and FIG. 4 is an enlarged view showing another embodiment, in which a tube 1 has a cylindrical body 2 formed of laminated paper, and a surface paper is provided on the circumferential surface. 3 are adhered. Both end surfaces or one end surface of the cylindrical body 2 are formed such that an inner peripheral side surface of the end surface is formed on a plane 2a substantially parallel to a surface in a direction orthogonal to the longitudinal direction of the axis. A shape in which an inclined surface 2b protruding in the axial direction toward the outer peripheral portion of the plane is formed, and a ridge portion 2c connecting the inclined surface 2b and the outer peripheral surface of the cylindrical body is formed in an arc shape. It is.

In order to set the dimensions and shape of the tube 1,
Outer diameter (D) is 126 mm, inner diameter (d) is 110 m
m, the dimension (t2) of the inclined surface 2b at the end face of the cylindrical body 2 made of laminated paper having a thickness (t1) of 8 mm, and the angle (θ2) of the inclined surface 2b with respect to a vertical line in a direction orthogonal to the longitudinal direction of the axis. ) Are processed into various combinations, and a turret type described in the specification of Japanese Patent Application No. 5-136572 is formed by using these tubes to form a 75d polyester yarn at a yarn speed of 4500 m / min. When the winding yarn was switched by the winding machine, (Table 1) and (Table 2)
The result shown in FIG.

The same result can be obtained by using a turret type winder in which the tubes are pressed from the end of the spindle toward the support side and each tube is held on the spindle by the pressing force, instead of the above turret type winder. Can be obtained.

[0032]

[Table 1]

[0033]

[Table 2] Ideally, the flat surface 2a formed on the tube 1 is processed so that the angle (θ1) with respect to a vertical line perpendicular to the longitudinal direction of the axis becomes 0 ° as shown in FIG. Given that there is an error and that the tube is compressed and deformed in the longitudinal direction of the axis when the tube is tightened,
It is preferable to set the angle (θ1) to be within ± 2 °.

The dimension (t2) of the inclined surface 2b is, as shown in Table 1, when the tube outer diameter is 126 mm.
If it is 3 mm or less, the peripheral speed difference becomes large, the yarn tension extremely decreases, and the success rate of yarn switching greatly decreases. Therefore, the size of the inclined surface 2b from the circumferential surface of the tube to the plane 2a (t)
2) is preferably set to 4% or less of the tube outer diameter.

As shown in FIG. 3, the inclined surface 2b has an angle (θ2) with respect to a vertical line in a direction perpendicular to the longitudinal direction of the axis.
Ideally, processing is performed so as to reduce the angle. However, as shown in Table 1, when the angle (θ2) becomes 1 ° or less, the yarn switching success rate decreases to 90% or less due to poor yarn introduction. When (θ2) becomes 8 °, the yarn cannot be reliably caught, and the yarn switching success rate becomes 95% or less.

Therefore, in order to satisfy that the yarn can be introduced and reliably guided to the catching portion, and that the captured yarn can contact the inclined surface 2b and move quickly on the circumferential surface in order to satisfy the requirements. It is preferable to set the angle (θ2) in the range of 2 to 5 °.

When the ridge 2c connecting the above-mentioned inclined surface 2b and the outer peripheral surface of the cylindrical body has an arc having a radius of 3 mm as shown in (Table 2), the movement from the capturing portion to the circumferential surface becomes slow. The yarn end length protruding from the bunch winding part becomes 300 cm, and the yarn switching success rate becomes 95% due to failure to catch the yarn.

Therefore, it is preferable that the ridge 2c is formed in an arc shape having a radius of 2 mm or less.

The ridge portion 2c is preferably formed in an arc shape having a radius of 0.3 mm or more in order to prevent the yarn from being scratched or fuzzed by contact with the yarn.

Since the yarn catching force of the above-mentioned tube 1 is greatly affected by the roughness, the roughness of the inclined surface 2b is processed into a JIS Rmax 12S and a JIS Rmax 12S.
A sample processed into Rmax 8S was prepared, and as shown in FIG. 11, a tube was subjected to a force of 10 kg in a direction perpendicular to the plane of the drawing and a 30 g tension was applied by a portable weighing scale 20 to 75 d. When the polyester filament yarn was gripped at a winding angle of 30 °, JIS Rmax 8S
In the case of JIS Rmax 12S, the yarn was cut.

Therefore, in order to reliably catch the yarn, it is preferable to process the inclined surface 2b to have a roughness of JIS Rmax 12S or more.

It is preferable that the inclined surface 2b is knurled in a twill shape or is formed into a substantially concentric parallel ridge shape.

FIG. 5 is an enlarged view of a portion II of FIG. 1 showing a shape of a tube according to a second embodiment of the present invention. The tube 1 has a cylindrical body 2 formed of laminated paper.
The surface paper 3 is adhered to the circumferential surface. And the cylindrical body 2
Are formed on planes 2a1, 2a2 substantially parallel to a plane perpendicular to the longitudinal direction of the axis, and the ridges 2c1, 2c2 connecting the planes 2a1, 2a2 and the outer peripheral surface of the cylindrical body are formed in an arc shape. The shape is formed as described above.

As in the case of the tube of the first embodiment, the ridges 2c1 and 2c2 are processed into various combinations in the same manner as in the case of the tube of the first embodiment. Was switched by a turret type winder under the condition of 4500 m / min, and the results as shown in Table 3 could be obtained.

[0045]

[Table 3] The dimensions of the ridges 2c1 and 2c2 formed on the tube 1 are 3 mm for the ridge 2c1 and 3 mm for the ridge 2c2 as shown in (Table 3).
If the combination is more than mm, the movement from the catching part to the circumferential surface becomes slow, the length of the yarn end protruding from the bunch winding part becomes 500 cm or more, and the diameter of the bottom part of the grip part becomes small, and the yarn The thread tension decreases and the thread switching success rate is 90%
It becomes below.

Therefore, it is preferable that the ridge 2c1 is processed into an arc having a radius of 2 mm or less, and the ridge 2c2 is processed into an arc having a radius of 2 to 4 mm.

FIG. 6 is a schematic sectional view showing the shape of a third embodiment of the tube of the present invention, and FIG. 7 is a schematic sectional view showing another embodiment of the third embodiment. Covers the end surface and the outer peripheral surface of the cylindrical body 2 formed at the both ends of the cylindrical body 2 formed by the laminated paper, the surface paper 3 adhered to the circumferential surface of the cylindrical body 2 and the cylindrical body 2, or one end thereof. The protection member 4 is provided.

The protective member 4 is preferably bonded to a thin paper having a thickness of 0.1 mm or less. A high-molecular material such as an ABS resin or a vinyl chloride resin is formed by injection molding into a bowl having a thickness of 0.5 to 2 mm, preferably 1 mm. A shaped article may be manufactured and pressed into the cylindrical body 1.

The above-described protective member 4 is in a state in which the circumferential surface of the cylindrical body 1 and the circumferential surface of the protective member 4 have a step as shown in FIG. 6, or the circumferential surface of the cylindrical body 1 as shown in FIG. The protective member 4 is attached by bonding or the like so that the circumferential surface of the protective member 4 has no step.

When the yarn is wound up by the tube 1 as described above, the captured yarn comes into contact with the inclined surface 2d or the flat surface 2a and is lifted by the frictional force, and immediately moves on the circumferential surface to be bunched. Since the winding 10b is formed,
The length of the yarn end (10a) protruding from the bunch winding portion can be made approximately 115 cm or less, and the bunch winding 10b can be formed at a position of 5 mm to 10 mm from the tube end surface.

The length of the above-mentioned yarn end 10a is measured by stretching the yarn in a straight state.
Since a is in a crimped state that occurs when the yarn is cut apart, its length is 20 to 30 cm.

Since the yarn end 10a is fixed by the bunch winding 10b, it is not released even if the yarn end 10a is pulled.

As a result, a yarn winding package in which a bunch winding 10b, a tail winding 10c, and a winding layer 10d for holding the yarn end 10a from the end side of the circumferential surface of the tube 1 as shown in FIG. 8 are sequentially formed. 10 can be obtained.

When the yarn is wound on the tube shown in FIG. 5, the yarn winding package 10 as shown in FIG. 9 is obtained, and when the yarn is wound on the tube shown in FIG. 6, the yarn as shown in FIG. The strip winding package 10 can be obtained.
