In FIG. 2, the code | symbol T is a well-known contact roller or a friction roller (henceforth a "contact roller") installed below the seal traverse unit U, and the some seal traverse unit U which comprises a seal traverse apparatus (U) is shown. Each can be installed independently, but one contact roller T common to the plurality of seal traverse units U can be provided. Reference numeral P is a package formed by winding a seal y on the bobbin mounted on the bobbin holder. The seal y is traversed by the seal traverse unit U described above, and then contacted and guided to a part of the circumferential surface of the contact roller T to be wound around the package P that is in contact with the contact roller T. It is.

Next, with reference to FIG. 3 and FIG. 4, the radiation winding machine provided with the seal traverse apparatus which provided the multiple unit traverse unit U mentioned above is demonstrated.

Reference numeral 22 denotes a turret lathe, and a pair of bobbin holders 23 are provided in the turret lathe symmetrically in a horizontal shape along the rotation center of the turret lathe 22. The bobbin holder 23 is comprised so that rotation drive may be carried out by the motor 24 provided in the turret lathe 22, respectively. The code | symbol B is a bobbin in which the slit b1 gripping the thread which started winding is formed, and it is attached in multiple numbers so that the edge part of the bobbin B adjacent to the bobbin holder 23 may approach or contact. When one bobbin holder 23 is rotated by the motor 24 and the thread y is wound around the bobbin B mounted on the bobbin holder 23 that is rotated, either bobbin holder 23 Motor 24 is stopped. Therefore, when the package P formed in the bobbin B attached to the bobbin holder 23 which is being rotated is full wound, the turret lathe 22 is rotated and filled by a suitable drive device (not shown). The bobbin holder 23 supporting the wound package P is separated from the contact roller T, and the bobbin holder 23 on which one of the empty bobbins B is mounted is mounted on the motor 24. Rotational drive by means of), and the winding bobbin B is brought into contact with the contact roller T to start winding. The yarn y continuous between the package P and the bobbin B wound up is cut | disconnected by making the yarn y wind up by the bobbin bin B. FIG.

Reference numeral 25 is a suitable bearing member for supporting the contact roller T so as to be free to rotate, and is arranged on the lifting frame F as the wound diameter of the package P increases. Moreover, the seal traverse unit U mentioned above is also provided in the lifting frame F. As shown in FIG.

Next, although the arrangement | positioning of the seal traverse unit U provided in multiple units parallel to the lifting frame F is demonstrated, since the seal traverse unit U is provided in even number arrangement normally, eight seal traverse units are provided in this embodiment. An example in which the U1 to U8 are provided in the lifting frame F is shown. Furthermore, the eight seal traverse units U are conveniently provided from the turret lathe 22 side toward the tip end of the bobbin holder 23. Signed U1 to U8 are sequentially attached.

The rotation planes of the upper rotary blade member 1 and the lower rotary blade member 7 of each seal traverse unit U1 to U8 are all arranged to be parallel to the rotation axis t1 of the contact roller T. And upper rotary wing members of the seal traverse units U1, U3, U5, U7, or seal traverse units U2, U4, U6, and U8 arranged in one arrangement. (1) and the rotation plane of the lower rotary blade member 7 are arrange | positioned so that it may become the same plane, respectively. Moreover, a part is inserted between the upper rotary blade member and the lower rotary blade member 7 of the seal traverse units U1 to U8, and a part is comprised so that it may overlap. For example, a part thereof is inserted between the upper rotary wing member 1 and the lower rotary wing member 7 of the seal traverse unit U1 disposed closest to the turret lathe 22, and the seal traverse unit U2. The lower rotary blade member 7 of the () is such that a portion thereof is inserted between the adjacent rotary traverse unit U1 and the upper rotary wing member 1 and the lower rotary wing member 7 of the seal traverse unit U3. do. Similarly, the lower rotary wing member 7 of the seal traverse unit U8 disposed farthest from the turret lathe 22 is the upper rotary wing member 1 and the lower rotary wing member (of the adjacent seal traverse unit U7). It is comprised so that the space | interval with 7) may become substantially the same as the thickness of the upper rotary blade member 1 and the lower rotary blade member 7.

As shown in FIG. 3, the seal traverse units U1 to U8 are compared to the seal traverse units U1, U3, U5, and U7 of the group closer to the contact roller T and the group thereof. Seal traverse unit U1, which is composed of two groups of seal traverse units U2, U4, U6 and U8 of the group away from the contact roller T, and closest to the turret lathe 22. Is installed at a position closer to the contact roller T, and the seal traverse unit U8 farthest from the turret lathe 22 is located at a position farther from the contact roller T than the seal traverse unit U1 described above. Will be installed.

As shown in FIG. 3, in this embodiment, both the rotation planes of the upper rotary wing member 1 and the lower rotary wing member 7 of each seal traverse unit U1 to U8 have the rotation axis of the contact roller T. As shown in FIG. It is arranged parallel to (t1) and between the adjacent rotary traverse units U of the rotary plane of the upper rotary blade member 1 and lower rotary wing member 7 of the one seal traverse unit U. The rotation plane is located, and the rotation plane of the upper rotary wing member 1 and the rotation plane of the lower rotary wing member 7 of all the seal traverse units U1 to U8 are configured in four planes.

Groups closer to the contact rollers T are the same lengths as the rotary shafts 15 of the seal traverse units U1, U3, U5, and U7, and are separated from the contact rollers T. The rotary traverses 15 of the seal traverse units U2, U4, U6, and U8 are also configured to have the same length. In addition, the length of the rotation shaft 15 of the group of group traverse units U1, U3, U5, and U7 closer to the contact roller T is the group of group traverse units separated from the contact roller T. The height difference between the two groups of the traverse units U (for example, the group of the group traversers closer to the contact rollers T) than the lengths of the rotation shafts of the U2, U4, U6, and U8. The distance of the lower rotary blade member 7 of the unit U1, U3, U5, U7 and the rotation axis t1 of the contact roller T from the contact roller T It is formed as long as the difference between the distance between the lower rotary blade member 7 of the traverse units U2, U4, U6, and U8 and the rotation axis t1 of the contact roller T. In this way, the pulleys 17 attached to the upper end of the rotary shaft 15 of each of the seal traverse units U1 to U8 are configured to have the same height.

Reference numeral 26 is a motor provided in the lifting frame F, and a pulley 27 is attached to the output shaft 26a of the motor 26. Reference numeral 28 denotes an endless end formed in the pulley 27 attached to the output shaft 26a of the motor 26 and the pulley 17 attached to the upper end of the rotation shaft 15 of each seal traverse unit U1 to U8. It is a belt, and the code | symbol 29 is inserted in the endless belt 28 so that the endless belt 28 may be attached to the pulley 17 of each seal traverse unit U1-U8, and is attached to the opposite side to the pulley 17. An intermediate vehicle (idler) to be installed, and reference numeral 30 is a guide pulley suitably arranged to change the running direction of the endless belt 28. As described above, the pulley 17 attached to the upper end of the rotary shaft 15 of each seal traverse unit U1 to U8 is configured to have the same height, so that one endless belt 28 is provided. As a result, the respective traverse units U1 to U8 can be driven simultaneously.

In addition, the pulley driven by the endless belt 28 for rotating the upper rotary wing member 1 and the lower rotary wing member 7 of each seal traverse unit U1 to U8 is each seal traverse unit. Each of (U1 to U8) consists of one pulley 17, so that the upper rotary wing member and the lower rotary wing member are similar to the seal traverse unit disclosed in Japanese Patent Application Laid-Open No. 9-507824. In addition, the structure can be simplified compared to the rotation of the two pulleys rotated separately by the endless belt. Further, when the upper rotary blade member and the lower rotary wing member are respectively rotated separately by two pulleys driven by an endless belt, the pulley and the lower rotary wing member for rotating the upper rotary wing member are rotated. Since the rotation difference is caused between the pulley to be driven and the slip between the pulley and the drive belt for rotating the pulley, a normal thread (y) is passed between the upper rotary blade member and the lower rotary blade member. This problem arises that this is not done, but in the present invention, the pulley rotated by the endless belt 28 for rotating the upper rotary blade member 1 and the lower rotary blade member 7 has one pulley ( 17), the thread (y) turning due to the rotational difference between the two pulleys for rotating the upper rotary blade member and the lower rotary blade member, respectively, as described above There is no problem such as miss.

In addition, as in the seal traverse device disclosed in Japanese Patent Laid-Open No. 9-507824, the inclination of the rotary blade member of the seal traverse unit with respect to the rotation axis of the contact roller is driven in a direction in which the rotary blade member is inclined upwardly. The rotation plane of the high, the drive box (elevation frame) for receiving the drive belt, etc. becomes high, the axis of rotation of the pulley of the seal traverse unit gradually increases in the direction in which the rotary wing member is obliquely tilted upward, and finally The rotary shaft of the pulley of the stage traverse unit of the stage is extremely long, and there is a problem that a large load is applied to the bearing of the rotary shaft. However, in the present invention, the drive box does not become high, and the rotary shaft 15 of the pulley 17 is It is not extremely long.

Next, the influence of the so-called excess length in the traverse process is demonstrated using FIG.2 and FIG.5.

As described above, the thread traversed by being engaged with the upper rotary blade member 1 or the lower rotary blade member 7 via the traverse point guide 31 provided above the thread traverse unit U. (y) is in contact with the contact roller T positioned below the upper rotary wing member 1 and the lower rotary wing member 7 in about a quarter, and then contacts the contact roller T. Wound around the package P, where the thread y is engaged with the upper rotary blade member 1 or the lower rotary blade member 7 to the contact point Ta of the contact roller T, ) Is called the extra length Lf.

As shown by the solid line in FIG. 5, as an example, the thread y engaged with the lower rotary blade member 7 and conveyed in the left direction slows the lower rotary blade member 7 more slowly than the lower rotary blade member 7. Therefore, by being transferred in the left and right direction, the seal y is inclined between the engaging point 7d of the lower rotary blade member 7 and the contact point Ta of the contact roller T, and then the contact roller T. Is perpendicular to the rotation axis t1 of the contact roller T, and wound around the package P. Therefore, in the position of the droop on the left side shown by the dashed-dotted line in FIG. 5, the droop point 7e of the lower rotary blade member 7 is located more than the left end p1 of the package P to the left, At this point, the thread y is passed from the lower rotary wing member 7 to the upper rotary wing member 1.

As shown by broken lines in FIG. 5, the upper rotary wing member 1 and the lower rotary wing member 7 are positioned above the positions of the upper rotary wing member 1 and the lower rotary wing member 7 in the solid line position described above. Consider the case where it is located, that is, when the extra length Lf becomes long. Then, since the tipping point 7e of the seal y from the lower rotary wing member 7 located on the left side to the upper rotary wing member 1 is changed, as shown by the dashed-dotted line in FIG. In the case where Lf is long, the contact point Ta to the contact roller T, that is, the left end p1 of the package P, is h-contacted as compared to the case where the extra length Lf is represented by a short dashed line. It moves to the center of the package P along the rotation axis t1 of (T), and therefore the winding width W of the package P becomes narrow. This occurs even when the thread y is passed from the upper rotary wing member 1 located on the left side to the lower rotary wing member 7, and thus, the upper rotary wing member 1 and the lower rotary wing member ( The winding width of the package P traversed by 7) is narrowed by 2h. However, since the amount of the yarn y wound by the package P is the same, the wound of the package P formed by being traversed by the upper rotary wing member 1 and the lower rotary wing member 7 in the solid line position described above Compared to the diameter D, the excess length Lf of the above-mentioned broken line position is wound of the package P formed by being traversed by the longer upper rotary blade member 1 and the lower rotary blade member 7. The diameter tends to be large.

As mentioned above, when the excess length Lf becomes long, the winding width W of the package P becomes narrow, and the winding diameter D of the package P tends to become large. Therefore, in the example shown in FIG. 3, the extra length Lf of the seal traverse units U2, U4, U6, and U8 of the groove | room apart from the contact roller T is attached to the contact roller T. As shown in FIG. Since it is longer than the excess length Lf of the group of the closer traversal units U1, U3, U5, U7, the seal traverse unit U2 of the group away from the contact roller T, The winding width W of the package P formed by the U4, U6, and U8 is the group of seal traversers U1, U3, U3 of the group closer to the contact roller T. The winding of the package P formed by the U5 and U7 becomes narrower than the width, and the seal traverse units U2, U4, U6 and U8 of the group away from the contact roller T are also provided. The wound diameter D of the package P formed by the package P is formed by the seal traverse units U1, U3, U5, and U7 of the group closer to the contact roller T. ) Tends to be larger than the wound diameter.

However, as shown in FIG. 3, when the bobbin holder 23 is provided in the turret shelf 22 by letter type, the tip part of the bobbin holder 23 tends to bend downward, and the contact roller T There is a problem that the contact with is broken. Therefore, in the present embodiment, as described above, the seal traverse unit U8 farthest from the turret 23, that is, the seal traverse unit U8 provided on the most extreme end side of the bobbin holder 23, is a contact roller T. The thread farthest from the turret lathe 22 by setting it as a group traverse unit U of the group away from the contact roller T with an extra length Lf longer than the group traverse unit U of the group closer to). The wound diameter D of the package P formed by the traverse unit U8, that is, the seal traverse unit U8 provided on the outermost end side of the bobbin holder 23 is made large, and the contact roller T is contacted. It is comprised so that it may become more reliable.

On the contrary, the seal of the group in which the seal traverse unit U1 closest to the turret lathe 22, that is, the seal traverse unit U1 provided in the most recent portion of the bobbin holder 23 is closer to the contact roller T. When the excess length Lf is a group of traverse units U of a group away from the long contact roller T as compared to the traverse unit U, the traverse unit U1 is formed by the seal traverse unit U1 closest to the turret lathe 22. The wound diameter D of the package P becomes large, so that a force for pressing the bobbin holder 23 approaching the turret lathe 22 downward is generated, and the tip of the bobbin holder 23 is more contact roller ( Away from T). In order to solve this problem, the seal traverse unit U1 closest to the turret lathe 22, that is, the seal traverse unit U1 provided at the most recent distal end of the bobbin holder 23, has a short length Lf. The wound diameter D of the package P formed by the seal traverse unit U1 closest to the turret lathe 22 is set as the seal traverse unit U of the group closer to the contact roller T. It is comprised so that it may become small and suppress generation | occurrence | production of the force which presses the bobbin holder 23 downward.

Next, another Example of the seal traverse unit U provided in the lifting frame F is demonstrated using FIG.

As described above, the lengths of the rotation shafts 15 of the seal traverse units U1, U3, U5, and U7 of the group closer to the contact roller T and the group separated from the contact roller T When changing the lengths of the rotary shafts 15 of the seal traverse units U2, U4, U6, and U8, two kinds of seal traverse units U having different lengths of the rotary shafts 15 are manufactured. The cost of the seal traverse unit U, and furthermore, the cost of the seal traverse device increases. In the present embodiment, in order to solve the above problem, all the traverse units U have the same structure, including the same length of the rotation shaft 15.

The structures of all the seal traverse units U are formed in the same manner, and the seal traverse units U are provided in the seal traverse units U2, U4, U6, and U8 of the group separated from the contact roller T. Height adjusting spacer S between the drive box u1, which accommodates the transmission mechanisms 12, 16, 18, and 20, and the frame f1 of the lifting frame F. ) Is inserted and separated from the contact roller T in comparison with the seal traverse units U1, U3, U5 and U7 of the group closer to the contact roller T by the spacer S. Configure.

In addition, the drive boxes u1 of the seal traverse units U2, U4, U6, and U8 of the group separated from the contact roller T are formed in the same structure as that of all the seal traverse units U. When the spacer S is inserted between the frame f1 and the lifting frame F, the height of the pulley 17 is different between the adjacent seal traverse units U. In this way, when the heights of the pulleys 17 are different, if the width 17a of the drive belt 28 of the pulley 17 is made approximately equal to the width 28a of the drive belt 28, all the pulleys ( 17, the driving belt 28 is not caught. Therefore, in the present embodiment, the seal traverse unit adjacent to the width 17a of the drive belt 28 of the pulley 17 of the seal traverse unit U is closer than the width 28a of the drive belt 28. The seal traverse unit (U) having a wider range than the step of rotation planes of the upper rotary blade members (U) of (U) and having the spacer (S) inserted therein, and the seal traverse unit having no spacer (S) inserted therein ( It is comprised so that the drive belt 28 may be caught in either of U).

The endless belt 28 described above is used as a toothed timing belt, and the pulley 17 which is driven by the timing belt and attached to the upper end of the rotating shaft 15 is used as a toothed pulley. The seal traverse device with which the endless belt 28 constituted by the timing belt and the pulley 17 composed of the toothed pulley can be prevented, and thus, the thread can be reliably passed and the traverse is stable. Can be realized. Further, the endless belt 28 is a timing belt having teeth formed at both ends thereof, and includes pulleys 17 attached to the upper end of the rotating shaft 15, and other pulleys 27, 29, ( By using 30) as a pulley with teeth, more reliable thread turning can be performed, and a real traverse device with stable traverse can be realized.

This invention has the structure as demonstrated above, and the effect described below can be acquired.

The rotational end surfaces of the upper rotary wing member and the lower rotary wing member of each seal traverse unit are arranged to be parallel to the rotation axis of the contact roller, and the rotation plane of the upper rotary wing member of all the seal traverse units and the lower rotary wing member The planes of rotation are arranged in four planes, and can be operated independently for each seal traverse unit without considering a driving timing or the like between adjacent seal traverse units. In addition, by arranging the seal traverse unit horizontally without inclining it, it is possible to prevent the drive box of the seal traverse unit from becoming high and to prevent the rotation shaft to which the pulley is attached from becoming long, thus the load applied to the bearing of the rotation shaft. Is reduced to prolong the bearing life. Furthermore, the seal traverse device can be made compact.

Between adjacent seal traverse units, between the rotation plane of the upper rotary wing member of one seal traverse unit and the rotation plane of the lower rotary wing member, the rotation plane or lower rotation of the upper rotary wing member of the other seal traverse unit Since the plane of rotation of the wing member is located, the seal traverse device can be further miniaturized.

By forming the pulley of each seal traverse unit more widely than the step | step difference between the rotation planes of the upper rotary wing members of the seal traverse unit adjacent to the width | variety of a drive belt, the seal traverse unit which comprises a seal traverse apparatus is made into the same structure. Therefore, the cost of the seal traverse unit U and furthermore, the cost of the seal traverse device can be reduced.

By configuring all seal traverse units to be driven by one drive belt, the thread traversing can be performed reliably, and the seal traverse device can be provided with a small size and a simplified driving mechanism.

In addition, by detecting the torque (load applied to the motor) of the motor for driving the drive belt, the interruption of the belt can be easily found.

The seal traverse device is arranged such that the upper planes of rotation of the upper rotor blades and lower rotor blades of each seal traverse unit are parallel to the rotation axis of the contact roller, and the upper rotor blades of all the seal traverse units are rotated. By arranging the planes of rotation of the plane and the lower rotary blade members in four planes, it is possible to operate independently for each seal traverse unit without considering the driving timing or the like between adjacent seal traverse units. Also, the seal traverse unit disposed on the uppermost end side of the bobbin holder is arranged to be farther from the contact roller than the seal traverse unit disposed on the most recent distal side of the bobbin holder, thereby being formed by the seal traverse unit provided on the uppermost side of the bobbin holder. It is possible to prevent the package from being in contact with the contact roller.

Between adjacent seal traverse units, between the rotation plane of the upper rotary wing member of one seal traverse unit and the rotation plane of the lower rotary wing member, the rotation plane or lower rotation of the upper rotary wing member of the other seal traverse unit By positioning the plane of rotation of the wing member, it is possible to reduce the difference in the extra length between the adjacent seal traverse units.

By making the gap between the upper rotary blade member and the lower rotary blade member a thin rotary blade thickness, the difference in the extra length between the neighboring seal traverse units can be made small to a degree where there is no problem.
