Description
- The invention relates to a yarn traverse apparatus that is used when a yarn is wound onto a bobbin. In particular, the invention is applicable to a yarn traverse apparatus for traversing many yarns simultaneously.
- WO-A-9602453, which is a document according to Article 54 (3) EPC, describes a yarn traverse apparatus with several adjacent traverse units each being equipped with two blade bodies rotating in opposite directions. The rotating blade bodies of adjacent winding heads overlap each other and the rotor axes are angularly arranged. For attaining that the difference between the towed lengths at the points of reversal are smaller than the distance between two intersection lines formed by the planes of rotation cutting the yarn traversing plane, said document suggests a range of an angle ε which is 0 < ε < 2tan-1 (d/(W * sin)). Said angle ε is defined as a predetermined acute angle as viewed from the front side of the traverse apparatus in a direction perpendicular to a yarn traversing plane. Said yarn traversing plane includes the left and right points of reversal and an upward position from which the yarn is delivered to said blade bodies. In said formula, is the angle between the traverse plane of the yarn and said rotational planes and d is defined as being the distance between the first and second rotational planes as viewed horizontally from a lateral side of the traverse apparatus. Said traverse width W is defined as being the length of the traverse direction along which the yarn is traversed, which is also called the stroke of a traverse unit.
- Another yarn traverse apparatus, publicly known, which traverses many yarns simultaneously is generally constructed so that a plurality of yarn traverse mechanisms are arranged one adjacent to another for the respective yarns, and each yarn traverse mechanism traverses the corresponding yarn by delivering the yarn between oppositely rotating blade bodies provided in each mechanism as a set. Various attempts have been made for improving such yarn traverse apparatus, as disclosed in US Patents 4,505,436, 4,505,437 and 4,646,983 and Unexamined Japanese Patent Publication No. Hei. 5-24740.
- In the Unexamined Japanese Patent Publication No. Hei. 5-24740, each yarn traverse mechanism is arranged offset axially from the adjacent yarn traverse mechanism so that only one of the blade bodies in the yarn traverse mechanism rotates on the single, same plane with respect to one of the blade bodies in the adjacent yarn traverse mechanism.
- Further, since the one blade body in the traverse mechanism and the one blade body in the adjacent traverse mechanism rotate on the same plane, once the blade body of either of the traverse mechanisms is out of a predetermined phase difference, the adjacent blade bodies may have, in some cases, interfered with one another and broken.
- It is the object of the present invention to provide an improved yarn traverse apparatus enabling a proper winding of the yarn and avoiding an interference of the blade bodies.
- This object is attained with a yarn traverse apparatus having the features cited in claim 1.
- Because of the special inclined arrangement of the first and second rotation planes, in case where a plurality of yarn traverse units are provided one adjacent to another, each of the first and second planes of the first unit is displaced axially from either of the first and second planes of the second unit, in order to avoid any interferences between the blades of the adjacent units.

- Fig. 2 is a diagram as viewed from an arrow A in Fig. 1.
- Fig. 3 is a diagram as viewed from an arrow B in Fig. 1.
- Fig. 4 is a detailed view of a portion C in Fig. 2.
- Fig. 5 is a sectional view taken along a line X-X in Fig. 3.
- The invention will now be described in detail with reference to an embodiment shown in the drawings. Fig. 1 is a front view showing a contact roller and a traverse apparatus; Fig. 2 is a diagram as viewed from an arrow A in Fig. 1; Fig. 3 is a diagram as viewed from an arrow B in Fig. 1; Fig. 4 is a detailed view of a portion C in Fig. 2; and Fig. 5 is a sectional view taken along a line X-X in Fig. 3.
- In Fig. 5, reference numeral 1 denotes the main body of a traverse mechanism. A
shaft 2 is secured to the main body 1 while attached to a shaft attachment hole la formed in the upper portion of the main body 1. - A
hollow shaft 3 is cylindrical and is rotatably supported bybearings shaft 2. An external gear 3a is integrally formed with the upper outer circumference of thehollow shaft 3. It may be noted that adistance piece 31 is interposed between thebearings stopper ring 5 stops thehollow shaft 3 and thebearings shaft 2. - A hollow shaft 6 is cylindrical and is of such a size as to accommodate the
hollow shaft 3 therein. The hollow shaft 6 is rotatably supported by arecess 1b on the lower side of the main body 1 throughbearings reference numeral 15 denotes a bearing press, which is attached to the main body by abolt 16 to press thebearing 14b. - The main body 1 has the
recess 1b formed on the lower side thereof and has an opening 1c communicating with therecess 1b formed so as to run in parallel with the shaft attachment hole la. A shaft 7 is supported bybearings 8a, 8b arranged inside the opening 1c so as to be rotatable with respect to the main body 1. It may be noted that astopper ring 9 allows the bearing 8a to be fixed to the main body 1. Adistance piece 10 is interposed between thebearings 8a, 8b. - Not only a
screw gear 11 is put over the shaft 7 that projects from the main body 1, but alsoexternal gears - The
internal gear 12 is tightened by abolt 13 on top of the hollow shaft 6. Theinternal gear 12 is meshed with thegear 7b of the shaft 7 and transmits the rotation of the shaft 7 to the hollow shaft 6. Further, thegear 7a of the shaft 7 is meshed with the gear 3a of thehollow shaft 3 and transmits the rotation of the shaft 7 to thehallow shaft 3. It may be noted that the reduction ratio of the gear 7 to thegear 12 is set to a value equal to the reduction ratio of thegear 7a to the gear 3a, so that the rotation of the shaft 7 allows thehollow shafts 3, 6 to rotate at an equal speed in opposite directions. - A
blade body 17 is arranged by integrally forming threeblades main body 17 is attached to the lower surface of the hollow shaft 6 by abolt 19. When the shaft 7 (Fig. 5) rotates, the blademain body 17 is caused to rotate clockwise as viewed in Fig. 3. - Similarly, a
blade body 18 is arranged by integrally forming threeblades main body 18 is attached to the lower surface of thehollow shaft 3 by abolt 20. When the shaft 7 (Fig. 5) rotates, the blademain body 18 is caused to rotate counterclockwise as viewed in Fig. 3. - As shown in Fig. 3, the center of rotation b of the
blade body 17 and the center of rotation a of theblade body 18 are arranged so as to be eccentric in opposite directions a predetermined distance L/2 from the traverse center O in the traverse direction. Because of the eccentric arrangement, the rotation loci respectively created by theblades blade body 17 and theblades blade body 18 intersect with each other in a plane view of Fig. 3 to define traverse ends at which the delivery of the yarn from one blade of theblade body 17 to one blade of theblade body 18 or vice verse is effected reliably. - A
guide rail 21 is secured to the bearing press 15 (Figs. 3 and 5), and through moving the yarn carried by theblade bodies yarn guide portion 21a, a traverse speed is set to a predetermined value. - The yarn carried from right to left by the
blade 17a in Fig. 3 this way meets theblade 18a at the traverse end on the left, and the yarn is released from theblade 17a by theblade 18a; then, the yarn is carried from left to right by theblade 18a; and theblade 18a meets theblade 17c at the traverse end on the right, and the yarn is released from theblade 18a by theblade 17c. The yarn is similarly carried in the opposite directions. - This is how a single traverse unit U (traverse mechanism) is constructed. That is, the traverse unit is a mechanism for winding a single package. The traverse apparatus of the invention is designed to prepare a plurality of packages. Not only the loci of rotation of a set of adjacent units out of a plurality of traverse units partially intersect in a plan view of Fig. 3, but also, as shown in Fig. 2, each unit U is arranged at a predetermined angle of inclination α with respect to a horizontal straight line H.
- As shown in Fig. 4, this angle of inclination α is set to a sufficiently large value. With respect to the
blade bodies - β =
- sin-1 (outer dimension C of the blade / distance D between adjacent traverse units)
- β' =
- sin-1 ((outer dimension C of the blade + 5 mm) / distance D between adjacent traverse units)
- γ =
- sin-1 ((outer dimension C of the blade + 0.3 mm) / distance D between adjacent traverse units)
- It may be noted that by the distance between the adjacent traverse units it is intended to mean a distance between the corresponding positions of the two traverse units that are arranged adjacent to each other and that by the outer dimension C of the blade it is intended to mean a value obtained by adding the thicknesses of the upper and lower blades to a distance d between such upper and lower blades.
- On top of the respective traverse units extends a
horizontal shaft 24 in the traverse directions. Not only a drive motor (not shown) is coupled to an end of theshaft 24 close to the outer side of the traverse apparatus, but also screwgears shaft 24 equidistantly. The screw gears 24a to 24e engage with the screw gears 11 on top of the shafts 7 of the units U to rotate the shafts 7 of the units U in the same direction by the motor, respectively. As long as the rotation of theshaft 24 can be transmitted to the shafts 7 of the respective units U that are substantially orthogonal to theshaft 24, therespective screw gears 24a to 24e and the screw gears 11 may be arranged by combining, e.g., worms with worm wheels or combining bevel gears, and the like. - A contact roller 22 (Fig. 1) is arranged at the lower portion of the each traverse unit U, so that the yarn traversed by the each traverse unit U is printed on the
contact roller 22 and wound onto bobbin holder (not shown) that rotates while coming in contact with thecontact roller 22. - The invention is characterized as arranging the traverse apparatus so that adjacent blades will not interfere with each other by inclining the blades at a predetermined sufficiently large angle of inclination. Therefore, it becomes easy to install and remove the traverse apparatus.
- A yarn carried from right to left by the
blade 17a in Fig. 3 this way meets theblade 18a at the traverse end on the left, and the yarn is released from theblade 17a by theblade 18a; the yarn is carried from left to right by theblade 18a; and then, theblade 18a and theblade 17c meets at the traverse end on the right, and the yarn is released from theblade 18a by theblade 17c. The yarn is carried in the opposite directions in a similar operation. Yarns are similarly traversed sequentially. Therefore, when a single traverse unit is observed, the position at which the yarn is released from theblade 17a at the left traverse end and the position at which the yarn is released from theblade 18a at the right traverse end are close to the single horizontal straight line H.
