Japanese Patent Laid-Open No. 5-266736

  FIG. 14: is a schematic block diagram which shows the twisting machine of the said patent document 1, and is the figure which looked at the twisting machine from the top. The twisting machine 100 includes four guides in a twisted path from a strand supply device (see the cradle 107) for supplying a plurality of strands to a twisted wire winding device (see the cradle 111) for winding a twisted wire. Rollers R1, R2, R3, and R4 are provided. The strand supply device (cradle 107) and the stranded wire take-up device (cradle 111) are arranged side by side in the vertical direction in FIG. 14, and by this arrangement, the stranded wire path extends from the strand supply device (cradle 107). A part (front part) reaching the second guide roller R2 via the one guide roller R1 and a part (rear part) reaching the stranded winding device (cradle 111) via the fourth guide roller R4 from the third guide roller R3 Side part).

  In FIG. 14, the front portion of the twisted wire path is disposed on the lower side, while the rear portion is disposed on the upper side, and the twist is fed from the second guide roller R2 disposed at the end of the front portion of the twisted wire path. The line is detoured to the left side in FIG. 14 and guided upward, and is guided to the third guide roller R3 disposed at the tip of the rear portion of the stranded wire path. A plurality of strands are twisted twice by the first and second guide rollers R1 and R2 at the front portion (route portion disposed on the lower side) of the stranded wire path, and the rear portion ( The stranded wire is further twisted twice by the third and fourth guide rollers R3 and R4 in the path portion disposed on the upper side, and the total four times is twisted.

  The stranded wire machine 100 has a first two-degree twist buncher 101 that twists twice at the front portion of the twisted wire path and a second two-degree twist buncher 102 that twists twice at the rear portion of the twisted wire path as basic configurations. And a transmission mechanism 106 for transmitting the driving force of the motor 105 to the first and second twisted bunchers 101 and 102, and the first twice twisted buncher 101 and the second twice twisted buncher 101, 102. The twist buncher 102 is arranged side by side in the vertical direction in FIG.

  The first twice-twisted buncher 101 is provided with a floating frame 103 for guiding a stranded wire and forming a stranded wire path so as to be rotatable. The first guide is mounted on a rotating shaft that supports both ends of the floating frame 103. A roller R1 and a second guide roller R2 are provided. Similarly, a floating frame 104 is also rotatably provided in the second double twist buncher 102, and a third guide roller R3 and a fourth guide roller R4 are provided on a rotation shaft that supports both ends of the floating frame 104. The rotational force of the motor 105 is transmitted to the rotating shafts of the floating frames 103 and 104 by a transmission mechanism 106 including a plurality of line shafts, belts, and the like, whereby the floating frame 103 and the first and second guide rollers R1 and R2 are transmitted. The floating frame 104 and the third and fourth guide rollers R3 and R4 are driven to rotate synchronously.

  A supply reel 108 around which the strand group S is wound is provided inside the cradle 107 of the first double twist buncher 101, and the strand supplied from the supply reel 108 is connected to the first guide roller R1 and the float. Guided by the frame 103 and the second guide roller R2, the floating frame 103 and the first and second guide rollers R1, R2 are twisted twice in the first double twist buncher 101 by rotating around the rotation axis. . The twisted wire twisted twice is compressed by the first compression die 109 and supplied to the second twisted buncher 102 while being pulled by the first capstan 110.

  The stranded wire twisted twice by the first double twist buncher 101 is guided by the third guide roller R3, the floating frame 104, and the fourth guide roller R4 of the second double twist buncher 102, and the floating frame 104 and the third guide roller R4 are guided. The fourth guide rollers R3 and R4 are further twisted twice in the second double twist buncher 102 by rotating around the rotation axis. Then, the stranded wire twisted four times is compressed by the second compression die 113 while being taken up by the second capstan 112 provided inside the cradle 111, and is wound around the take-up reel 114.

  In the stranded wire machine 100 shown in FIG. 14, two twice-twisted bunchers having substantially the same configuration are provided, which increases the manufacturing cost of the equipment and requires a large space for installing the stranded wire machine 100. There is a problem.

  In addition, the stranded wire path from the supply reel 108 in the first double twist buncher 101 to the take-up reel 114 in the second double twist buncher 102 has a strand from the supply reel 108 in the first double twist buncher 101. A path that is pulled out to the right, reversed by the first guide roller R1 and the floating frame 103, led to the second guide roller R2 disposed on the left side of the supply reel 108, and then pulled out from the first double twist buncher 101. When the stranded wire drawn from the first twelfth twist buncher 101 is input via the first compression die 109 and the first capstan 110, the second twist twist buncher 102 The three guide rollers R3 and the floating frame 104 led to the fourth guide roller R4 arranged on the right side of the take-up reel 114. In addition, since there is a path that is reversed by the fourth guide roller R4 and wound around the take-up reel 114, the path in the first and second twisted bunchers 101 and 102 is long, and further, the first second time. Since a path for guiding the stranded wire drawn from the stranded buncher 101 to the second twice-twisted buncher 102 is also required, the stranded wire path is generally long.

  For this reason, adjustment of the tension | tensile_strength with respect to the stranded wire inside each of the 1st, 2nd degree twist buncher 101,102 at the time of twisted wire manufacture, and the path | route from the 1st 2nd degree twist buncher 101 to the 2nd 2nd degree twist buncher There is a problem that becomes difficult. In addition, since the compression dies 109 and 113 for increasing the compression rate are provided at two locations in the middle of the path, the first capstan 110 and the second capstan 112 for taking the stranded wire cannot be provided in the middle of the path. In addition, there is a problem that it is difficult to synchronize the take-up speed between these capstans.

  Furthermore, when a strand is a comparatively hard material, such as a steel wire, for example, a mechanism for performing a twisting process is provided on the strand supply device side, but the strand wire machine 100 shown in FIG. 14 supplies the strand. Since the supply reel 108 is provided inside the first double twist buncher 101, there is no space for a mechanism for performing the twisting process, and the twisting process can be performed when applied to a strand such as a steel wire. However, there is an inconvenience that it is difficult to apply to a wire such as a steel wire substantially.

  The present invention has been conceived under the circumstances described above, and can be applied to both soft wire and steel wire.

  Other features and advantages of the present invention will become more apparent from the detailed description given below with reference to the accompanying drawings.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the accompanying drawings.

  First, the basic configuration of the four-degree twisting operation in the twisting machine according to the present invention will be described with reference to FIG.

  The stranded wire machine according to the present invention includes four turn rollers B1 to B4 that rotate around a center line M passing through the center of the twisting die A as a rotation axis. The four turn rollers B1 to B4 are members that perform the function of twisting the wire during the conveyance while guiding the conveyance of the wire. The four turn rollers B1 to B4 are arranged in a row in the order of twisting die A to B1, B4, B3, and B2 along a center line M (hereinafter referred to as “rotating axis M”), and a fourth twist is performed. Between the turn roller B4 to be performed and the turn roller B3 to be twisted for the third time, a stranded wire winding portion C for winding the stranded wire S ′ twisted four times is disposed. Further, in the vicinity of each of the turn rollers B1 to B4, stranded wire guides D1 to D1 for forming a stranded wire path for guiding the plurality of strands S supplied from the stranded die A to the stranded wire take-up portion C while twisting them. D4 is provided. These stranded wire guides D1 to D4 also rotate around the rotation axis M.

  Therefore, as shown in FIG. 1, the stranded wire path of the stranded wire machine according to the present invention reaches the first turn roller B1 from the twisting die A along the rotation axis M, and is guided by the first stranded wire guide D1. After detouring to the outside of one end, the second stranded wire guide D2 leads to the second turn roller B2, and again returns to the inner third turn roller B3 along the rotation axis M, and the third stranded wire guide D3 After detouring to the outside again, after returning to the fourth turn roller B4 by the fourth twisted wire guide D4, the route reaches the twisted wire winding portion C along the rotation axis M.

  In the twisting machine according to the present invention, the first turn roller B1 and the second turn roller B2, and the third turn roller B3 and the fourth turn roller B4 are opposite to each other around the rotation axis M. Rotate at the same rotational speed.

  Since the first stranded wire guide D1 and the second stranded wire guide D2 are fixed to the rotation shafts of the first guide roller B1 and the second guide roller B2, respectively, the first turn roller B1 and the second stranded wire guide D2 It will rotate with the turn roller B2. That is, the first stranded wire guide D1 and the second stranded wire guide D2 rotate in the same direction at the same rotational speed. Further, since the third stranded wire guide D3 and the fourth stranded wire guide D4 are fixed to the rotation shafts of the third turn roller B3 and the fourth turn roller B4, respectively, 4 turn rollers B4.

Is shown. The white arrow indicates the direction of conveyance of the stranded wire S '.

  With the configuration described above, in the stranded wire machine according to the present invention, each turn roller of the first turn roller B1 to the fourth turn roller B4 rotates around the rotation axis M, so that a plurality of turn rollers are provided at each turn roller portion. Twisting operation is performed on the strand S, and four-twisting is performed before reaching the stranded wire winding portion C. Note that the rotation directions of the first turn roller B1 and the second turn roller B2, and the third turn roller B3 and the fourth turn roller B4 are opposite to each other, as shown by arrows in FIG. The twist direction of the stranded wire S ′ between the second turn roller B2 and the third turn roller B3 is relative to the twist direction of the stranded wire S ′ between the twist die A and the first turn roller B1. Since the directions are opposite, if the rotation direction of the third turn roller B3 and the fourth turn roller B4 is not opposite to the first turn roller B1 and the second turn roller B2, the twist is returned to 4 This is because the twist does not occur.

  In the stranded wire machine according to the present invention, two rotation shafts arranged in a line on the same axis (for example, refer to the rotation shaft of the first turn roller B1 and the rotation shaft of the fourth turn roller B4 in FIG. 1). Although it is necessary to rotate in the opposite direction, if the drive source of the two rotation shafts is made common and the rotational force of the drive source is transmitted to one rotation shaft in the same rotation direction, the rotation of the drive source is transmitted to the other rotation shaft It is necessary to transmit the force in the opposite direction of rotation. As described above, in the stranded wire machine 1 according to the first embodiment, the rotational force of the motor 20 is transmitted to the first rotating shaft 6 and the second rotating shaft 7 in the same rotational direction. The rotary shaft 8 and the fourth rotary shaft 9 are configured to transmit the rotational force of the motor 20 in the reverse direction using a differential device.

  FIG. 9 is a perspective view showing the basic configuration of the differential gear employed in the stranding machine 1 according to the first embodiment.

  In the differential device shown in the figure, the second rotating shaft U2 is rotatable through a bearing at the tip of the first rotating shaft U1 with its rotating shaft coinciding with the rotating shaft of the first rotating shaft U1. Is attached. An arm E protrudes from the first rotating shaft U1, and a shaft is attached to the tip of the arm E so as to be parallel to the rotating shaft of the first rotating shaft U1 and to be rotatable. Gears G3a and G3b are fixed. On the other hand, a gear G1 is formed at the base end of the second rotating shaft U2, and the gear G1 and the gear G3a are engaged with each other. Further, a concave gear G2 with teeth formed inside is rotatably attached to the first rotation shaft U1, and the gear G3b is meshed with the gear G2.

  The gears G1 and G2 are sun gears that rotate around the center axis X of the first rotation axis U1 and the second rotation axis U2, and the pair of gears G3a and G3b are planetary gears that revolve around the center axis X. The sun gears G1, G2 and the planetary gears G3a, G3b constitute a differential gear train.

  In the configuration of FIG. 9, the counterclockwise rotation direction (for example, the rotation direction of the arrow a) when viewed in the direction of the central axis X is defined as a positive rotation, and the first rotation axis U1 is counterclockwise as indicated by the arrow a. When rotating clockwise, the planetary gears G3a and G3b revolve and rotate counterclockwise as indicated by arrows b and c, so the first sun gear G1 rotates clockwise as indicated by arrow d, The second sun gear G2 rotates counterclockwise as indicated by an arrow e. That is, the second rotating shaft U2 rotates in the direction opposite to the first rotating shaft U1.

  Therefore, if the differential shown in FIG. 9 is applied so that the first rotation axis U1 corresponds to the first rotation axis 6 and the second rotation axis U2 corresponds to the fourth rotation axis 9, the fourth rotation The rotary shaft 9 can be arranged in a line coaxially with the first rotary shaft 6 and rotated in the opposite direction to the first rotary shaft 6. Similarly, if the differential shown in FIG. 9 is applied so that the first rotation axis U1 corresponds to the second rotation axis 7 and the second rotation axis U2 corresponds to the third rotation axis 8, The three rotation shafts 8 can be arranged in a line coaxially with the second rotation shaft 7 and rotated in the opposite direction to the second rotation shaft 7.

  In the differential shown in FIG. 9, the number of teeth of each gear of the first sun gear G1, the planetary gears G3a, G3b, and the second sun gear G2 is Z1, Z2, Z2, Z3, The rotation speeds of the sun gear G1 and the second sun gear G2 are N1 and N3, the rotation speeds of the planetary gears G3a and G3b are N2, and the rotation speed of the first rotation shaft U1, that is, the revolutions of the planetary gears G3a and G3b. When the rotational speed is Na, the relational expression N3 = (1 + Z1 / Z3) Na− (Z1 / Z3) N1 = Na + k (Na−N1) (where Z1 / Z3 = k) is established.

  When the differential device shown in FIG. 9 is applied to the twisting machine 1 according to the present invention, the rotational speed Na of the first rotational shaft U1 and the rotational speed N1 of the second rotational shaft U2 need to be the same. Therefore, if the condition of Na = −N1 is put in the above equation, N3 = Na + 2k · Na, and the relational expression of N3 = (2k + 1) Na is established. Therefore, if the gear corresponding to the second sun gear G2 is rotated in the same direction as the first rotating shaft 6 at the rotational speed of (2k + 1) Na, the fourth rotating shaft 9 is reverse to the first rotating shaft 6. Can be rotated at the same rotational speed.

  Next, the configuration of the first differential device 10 and the fourth rotating shaft 9 will be described with reference to FIG. FIG. 5 is a diagram in which the portion A in FIG. 2 is extracted.

  If the basic configuration of the differential device of FIG. 9 is compared with the first differential device 10 shown in FIG. 5, the first rotating shaft 6 corresponds to the first rotating shaft U1 and the fourth rotating shaft is obvious. 9 corresponds to the second rotation axis U2. Accordingly, a support portion 602 is formed on the distal end side of the first rotary shaft 6 relative to the fixed position of the first bowl-shaped rotary body 28, while the base end portion (the left end portion in FIG. 5) of the fourth rotary shaft 9 is formed. ) Is provided with a concave supported portion 902 having an inner diameter substantially the same as the outer diameter of the support portion 602 of the first rotary shaft 6, and the supported portion 902 is supported by the first rotary shaft 6 via a bearing. The fourth rotating shaft 9 is mounted so as to cover the portion 602, and is rotatably supported on the tip end portion of the first rotating shaft 6.

  The fourth rotating shaft 9 functions as a rotating shaft of the fourth turn roller B4 and the fourth stranded wire guide D4 in FIG. 1, and the stranded wire S from the fourth turn roller B4 to the stranded winding portion C. It fulfills the function of guiding '. A fourth turn roller 27 corresponding to the fourth turn roller B4 in FIG. 1 is rotatably disposed on a side surface of the fourth rotating shaft 9 that is close to the supported portion 902, and is guided by the fourth turn roller 27. A space 9a for guiding the twisted wire S ′ to the cradle 12 side is provided from the position where the fourth turn roller 27 is disposed to the tip (right end in FIG. 5) along the axis.

  The mounting structure of the fourth turn roller 27 on the fourth rotating shaft 9 is formed on the surface of the fourth rotating shaft 9 and communicates with the space 9a, similarly to the mounting structure of the first turn roller 24 on the first rotating shaft 6. The pair of support pieces 901 (see FIG. 3) is configured so that the lower half is hidden in the substantially semicircular groove 9b and a part of the circumference coincides with the axis of the fourth rotation shaft 9. It is supported rotatably. When the fourth rotation shaft 9 makes one rotation, the fourth turn roller 27 makes one rotation around the axis of the fourth rotation shaft 9, and by this rotation operation, the third turn roller 27 is guided by a fourth hook-shaped rotating body 31 described later. A fourth twist is added to the second twisted wire (hereinafter, the twisted wire added with the fourth twist is referred to as “fourth twisted wire”).

  A substantially bowl-shaped fourth hook-like rotating body 31 corresponding to the fourth twisted wire guide D4 in FIG. 1 is attached to the fourth rotating shaft 9 in the vicinity of the left side of the fourth turn roller 27. The size of the fourth hook-shaped rotating body 31 is slightly smaller than that of the first hook-shaped rotating body 28. On the inner surface of the fourth hook-shaped rotator 31, as with the first hook-shaped rotator 28, a guide die for guiding a third-degree stranded wire to which a third-twist is added by a third turn roller 26 described later. A plurality of 311 are attached. Note that a plurality of dummy dies 312 for maintaining a balance during rotation is also arranged on the inner surface opposite to the mounting position of the guide die 311 in the fourth bowl-shaped rotating body 31. When the fourth rotating shaft 9 makes one rotation, the fourth bowl-shaped rotating body 31 makes one rotation with the fourth rotating shaft 9.

  A gear 50 corresponding to the first sun gear G1 in FIG. 9 is provided at the tip of the supported portion 902 of the fourth rotating shaft 9 (tip on the left side in FIG. 5).

  On the other hand, a concave gear 51 having teeth formed inside is rotatably attached to a position near the first turn roller 24 of the first rotating shaft 6 (on the left side of the first turn roller 24 in FIG. 5). Yes. The gear 51 corresponds to the second sun gear G2 in FIG. A support member 603 corresponding to the arm E in FIG. 9 protrudes from a portion between the gear 51 of the first rotation shaft 6 and the gear 50 of the fourth rotation shaft 9, and the support member 603 is provided at both ends. A shaft to which a pair of gears 52 and 53 are fixed is rotatably supported. The gear 52 and the gear 53 correspond to the planetary gear G3a and the planetary gear G3b of FIG. 9, respectively. The gear 52 meshes with the gear 50, and the gear 53 meshes with the gear 51.

  As described above, when the rotation speed of the first rotation shaft 6 is Na, the fourth rotation shaft 9 can be rotated in the reverse direction at the same rotation speed as the first rotation shaft 6. The gear 51 corresponding to the second sun gear G2 needs to be rotated in the same rotation direction as the first rotation shaft 6 at a rotation speed of (2k + 1) Na. For this reason, an eighth pulley 42 is provided on the outer surface of the gear 51 so that the rotational force of the line shaft 21 is transmitted to the gear 51 via the fourth belt 43.

  That is, the seventh pulley 41 is fixed to a position of the line shaft 21 facing the gear 51, and the fourth belt 43 is bridged between the seventh pulley 41 and the eighth pulley 42 of the gear 51 to output the motor 20. Is transmitted to the first differential device 10, and the gear 51 is rotated in the same direction as the first rotation shaft 6 at a rotational speed of (2k + 1) Na by this transmission mechanism.

  With this configuration, for example, when the first rotation shaft 6 rotates clockwise at the rotation speed Na, the gear 51 of the first differential device 10 rotates in the same direction as the first rotation shaft 6 at the rotation speed of (2k + 1) Na. Rotate. The gear 50 of the first differential device 10 is transmitted with the counterclockwise rotation of the rotation number Na based on the relationship between the number of teeth of the gear 51 and the gear 50, and the fourth rotation shaft 9 is the first rotation shaft. 6 and the second rotating shaft 7 rotate in the opposite direction to the first rotating shaft 6 and the second rotating shaft 7 in the opposite direction.

  The same applies to the third rotating shaft 8. As is apparent from the comparison between the basic configuration of the differential device shown in FIG. 9 and the second differential device 11 shown in FIG. 6, the second rotating shaft 7 performs the first rotation. The third rotation shaft 8 corresponds to the axis U1, and the third rotation shaft 8 corresponds to the second rotation shaft U2. Accordingly, a support portion 702 is formed on the distal end side of the second rotary shaft 7 relative to the fixed position of the second bowl-shaped rotating body 29, while the base end portion of the third rotary shaft 8 (the right end portion in FIG. 6). ) Is provided with a concave supported portion 802 having an inner diameter substantially the same as the outer diameter of the support portion 702 of the second rotating shaft 7, and the supported portion 802 is supported by the second rotating shaft 7 via a bearing. The third rotary shaft 8 is mounted so as to cover the portion 702, and is rotatably supported at the tip of the second rotary shaft 7.

  The third rotating shaft 8 functions as the rotating shaft of the third turn roller B3 and the third twisted wire guide D3 in FIG. 1, and the twisted wire S ′ guided from the second turn roller B2 is used as the third rotating shaft B3. It fulfills the function of guiding to the twisted wire guide D3. A third turn roller 26 corresponding to the third turn roller B3 in FIG. 1 is rotatably disposed on the side surface of the third rotating shaft 8 near the supported portion 802 and guided by the second rotating shaft 7. A space 8a for guiding the twisted wire S 'toward the third turn roller 26 is provided from the base end (right end in FIG. 5) to the position where the third turn roller 26 is disposed.

  The mounting structure of the third turn roller 26 on the third rotating shaft 8 is formed on the surface of the third rotating shaft 8 and communicates with the space 8a, similarly to the mounting structure of the first turn roller 24 on the first rotating shaft 6. The pair of support pieces 801 (see FIG. 3) is configured so that the lower half is hidden in the substantially semicircular groove portion 8b and so that a part of the circumference coincides with the axis of the third rotating shaft 8. It is supported rotatably. When the third rotating shaft 8 makes one rotation, the third turn roller 26 makes one rotation around the axis of the third rotating shaft 8, and by this rotating operation, the third turn roller 26 turns into a double twisted wire guided from the second rotating shaft 7. Add the third twist (hereinafter, the twisted wire with the third twist added is called "third twisted wire").

  A substantially bowl-shaped third hook-shaped rotating body 30 corresponding to the third twisted wire guide D3 in FIG. 1 is attached to the third rotating shaft 8 in the vicinity of the right side of the third turn roller 26. The size of the third bowl-shaped rotating body 30 is the same as that of the fourth bowl-shaped rotating body 31, and a plurality of guide dies 301 and dummy dies 302 are attached in the same manner as the fourth bowl-shaped rotating body 31. The third bowl-shaped rotating body 30 rotates once together with the third rotating shaft 8 when the third rotating shaft 8 rotates once.

  If the second differential device 11 is compared with the configuration of the first differential device 10 shown in FIG. 5 and the second differential device 11 shown in FIG. 6, the basic configuration is the same. Therefore, the description of the configuration of the second differential device 11 is omitted.

  The transmission mechanism for the second differential device 11 is also the same as the transmission mechanism for the first differential device 10. That is, the ninth pulley 44 is fixed to a position of the line shaft 21 facing the gear 55 of the second differential device 11 (corresponding to the second sun gear G2 in FIG. 9). A transmission mechanism is constructed that bridges the fifth belt 46 between the tenth pulley 45 and transmits the output of the motor 20 to the second differential device 11, and this transmission mechanism allows the gear 55 to rotate at (2k + 1) Na rotation speed. Thus, the second rotation shaft 7 is rotated in the same direction. Therefore, the third rotating shaft 8 rotates in the same direction as the fourth rotating shaft 9 and in the opposite direction to the first rotating shaft 6 and the second rotating shaft 7 and the same rotation as the first rotating shaft 6 and the second rotating shaft 7. Rotate by number.

  Next, the internal configuration of the cradle 12 will be described.

  The cradle 12 is a part corresponding to the stranded wire winding part C in FIG. The cradle 12 is provided with a rear over twister 13 near the right side of the fourth rotating shaft 9. The rear over twister 13 performs so-called molding on the four-degree stranded wire S ′ twisted four times by the fourth turn roller 27 by the rotation of the fourth rotating shaft 9. The rear over twister 13 is provided as necessary, for example, when the element wire is a hard material such as a steel wire.

  A take-up capstan 14 is provided at the rear stage of the rear over twister 13. The take-up capstan 14 is driven at a predetermined ratio with respect to the fourth rotating shaft 9 and draws the four-degree stranded wire S ′ from the rear over twister 13 toward the take-up bobbin 18. Although not described in detail, the take-up capstan 14 is connected to a transmission mechanism 60 provided on the fourth rotary shaft 9, and the take-up capstan 14 is rotationally driven by the rotational force of the fourth rotary shaft 9.

  A forced roller group 15 is provided in the vicinity of the take-up capstan 14. The forcing roller group 15 is a so-called ironing line for the four-degree stranded wire S ′ in order to remove undulations, kinks and the like by passing the four-degree stranded wire S ′ between a plurality of rollers arranged in a staggered pattern. Is to give The forcible roller group 15 is provided as necessary when the strand is made of a hard material such as a steel wire.

  A traverse device 17 is provided in the vicinity of the take-up capstan 14. The traverse device 17 moves the roller 17a repeatedly in the vertical direction in FIG. 3 so that the four-degree stranded wire S ′ sent from the take-up capstan 14 via the turn roller 16 is taken up by the take-up bobbin 18 in an orderly manner. belongs to. Although detailed description is omitted, the traverse device 17 is rotationally driven by transmitting the rotational force of the fourth rotating shaft 9 by the transmission mechanism 61.

  The winding bobbin 18 winds the four-degree stranded wire S '. The take-up bobbin 18 is rotationally driven by the transmission mechanism 62, although a detailed description is omitted.

  Next, the traveling path of the stranded wire in the stranded wire machine 1 will be described.

  The plurality of strands S that are finally twisted four times are taken into the twisting die 23 from the plurality of supply drums (not shown) installed outside through the eye plate 22, and the space 6 a of the first rotating shaft 6. It passes through and is hung on the first turn roller 24. The stranded wire (or strand) hung on the first turn roller 24 is guided by the guide die 281 of the first hook-shaped rotating body 28 and then guided by the guide die 291 of the second hook-shaped rotating body 29. The second turn roller 25 is suspended.

  The stranded wire S 'hung on the second turn roller 25 passes through the space 7a of the second rotating shaft 7 and the space 8a of the third rotating shaft 8, and is hung on the third turn roller 26. The stranded wire S ′ hung on the third turn roller 26 is guided by the guide die 301 of the third hook-shaped rotator 30 and then guided by the guide die 311 of the fourth hook-shaped rotator 31. It is hung on the turn roller 27. The stranded wire S ′ hung on the fourth turn roller 27 passes through the space 9a of the fourth rotating shaft 9, passes through the rear over twister 13, the take-up capstan 14, the forced roller group 15, the turn roller 16, and the traverse device 17. To the winding bobbin 18.

  Next, the twisting operation in the twisting machine 1 will be described.

  As described above, the plurality of strands S routed in the stranded wire machine 1 are totaled by the first to fourth turn rollers 24, 25, 26, and 27 when the motor 20 is driven to rotate. Four twists are added. That is, the plurality of strands S are twisted once by rotation around the rotation axis M of the first turn roller 24, twisted twice by rotation around the rotation axis M of the second turn roller 25, and the third turn roller 26. Is twisted three times by rotation around the rotation axis M, and twisted four times by rotation around the rotation axis M of the fourth turn roller 27.

  More specifically, when the motor 20 is rotationally driven, as described above, the rotational force of the motor 20 is transmitted via the line shaft 21 to the first rotating shaft 6, the second rotating shaft 7, and the first differential device. 10 and the second differential 11.

  When the first rotating shaft 6 rotates, the first turn roller 24 and the first bowl-shaped rotating body 28 rotate around the axis of the first rotating shaft 6. Thereby, the first twist is added to the strand S hung on the first turn roller 24.

  Further, when the second rotating shaft 7 rotates, the second turn roller 25 and the second bowl-shaped rotating body 29 rotate around the axis of the second rotating shaft 7. As a result, a second twist is applied to the stranded wire S ′ once hung on the second turn roller 25.

  When the second differential device 11 rotates, the third turn roller 26 and the third bowl-shaped rotating body 30 are moved around the axis of the third rotating shaft 8 along with the first rotating shaft 6 and the second rotating shaft. 7 rotates in the opposite direction. The third turn roller 26 and the third bowl-shaped rotator 30 rotate around the axis of the third rotation shaft 8, so that the second turn stranded wire S ′ hung on the third turn roller 26 has a third time. Twist is added.

  Further, when the first differential device 10 rotates, the fourth turn roller 27 and the fourth hook-shaped rotating body 31 are moved around the axis of the fourth rotating shaft 9 along with the first rotating shaft 6 and the second rotating shaft. 7 rotates in the opposite direction. The fourth turn roller 27 and the fourth bowl-shaped rotator 31 rotate around the axis of the fourth rotation shaft 9, so that the fourth turn roller 27 and the third twisted wire S ′ hung around the fourth turn roller 27 have a fourth time. Twist is added.

  The fourth twisted wire S ′ to which the fourth twist is applied by the fourth turn roller 27 is typed by the rear over twister 13 and taken up by the take-up capstan 14. Further, the four-degree stranded wire S ′ is ironed by the forcible roller group 15 and is taken up by the take-up bobbin 18 via the turn roller 16 and the traverse device 17.

  As described above, according to the twisting machine 1 according to the present embodiment, the first turn roller 24 that applies the first twist, the second turn roller 25 that applies the second twist, and the third twist that applies the third twist. The turn roller 26 and the fourth turn roller 27 to be twisted for the fourth time are arranged along the rotation axis M passing from the twist die 23 to the center of the twist die 23, the first turn roller 24, the fourth turn roller 27, The third turn roller 26 and the second turn roller 25 are arranged in this order, and the cradle 12 for winding the twisted wire S ′ twisted four times is arranged between the fourth turn roller 27 and the third turn roller 26. The twisting die 23 → the first turn roller 24 → the second turn roller 25 → the third turn roller 26 → the fourth turn roller 27 → the structure in which the twisting is performed four times through the stranded wire path of the cradle 12. Therefore, as compared with the conventional four-twist stranded wire machine (see FIG. 14) described in the background section, the two-twist bunchers are arranged side by side. The machine 1 can be made compact and the installation space can be reduced.

  Moreover, since the twisted wire machine 1 of this embodiment made the twisted wire path | route compact, since the length which draws around twisted wire S 'can be shortened as much as possible, compared with the conventional 4 degree twisted twisted wire machine, Adjustment of the tension with respect to the wire S ′ is easy, and the burden on the device for applying tension to the stranded wire S ′ can be reduced.

  In addition, as a differential device applied to the stranding machine 1 which concerns on 1st Embodiment, it may replace with the differential device shown in FIG. 9, and may use the differential device shown in FIG.

  In the differential device shown in FIG. 10, the gear G1 ′ corresponding to the first sun gear is formed with teeth on the inner side similar to the gear G2 corresponding to the second sun gear with respect to the differential device shown in FIG. 9. The planetary gear G3a 'meshed with the gear G1' has a larger size than the planetary gear G3b meshed with the gear G2.

  The relationship of the rotational operation of each gear G1 ', G2, G3a', G3b of the differential shown in FIG. 10 is the same as that of the differential shown in FIG. Therefore, the second rotating shaft U2 rotates in the opposite direction to the first rotating shaft U1.

  In the differential shown in FIG. 10, the number of teeth of each gear of the first sun gear G1 ′, the planetary gear G3a ′, the planetary gear G3b, and the second sun gear G2 is Z1, Z2, Z3, and Z4. The rotation speeds of the first sun gear G1 ′ and the second sun gear G2 are N1 and N4, the rotation speeds of the planetary gears G3a ′ and G3b are N2 and N3. When the revolution speed of the planetary gears G3a ′ and G3b is Na, the relational expression of N4 = (1−k ′) Na + k ′ · N1 (where k ′ = (Z1 · Z3) / (Z2 · Z4)) is obtained. To establish.

  If N4 = 0 in the above equation, Na-k '. (Na-N1) = 0, so if the condition of Na = -N1 is included in this equation, Na = k'.2Na. Therefore, the number of teeth Z1, Z2, Z3, and Z4 of each gear of the first sun gear G1 ′, the planetary gear G3a ′, the planetary gear G3b, and the second sun gear G2 is set so that k ′ = 0.5. When appropriately selected, the second rotating shaft U2 can be rotated in the opposite directions at the same rotational speed as the first rotating shaft U1 without rotating the second sun gear G2.

  In FIGS. 1, 5 and 6, when the first differential device 10 and the second differential device 11 are configured as the differential device shown in FIG. 10, gears 51 and 55 corresponding to the second sun gear G2 are used. Need not be rotated, the transmission mechanism (the seventh pulley 41, the eighth pulley 42, the fourth belt 43, the ninth pulley 44, the tenth pulley 45) that transmits the rotational force of the motor 20 to the gears 51, 55. The configuration of the fifth belt 46 becomes unnecessary, and the configuration of the twisting machine 1 can be further simplified.

  FIG. 11 is a side view showing a stranded wire machine according to a second embodiment of the present invention. This stranded wire machine 1A is different from the stranded wire machine 1 of the first embodiment in that a substantially arcuate rotator is used instead of the first to fourth saddle-like rotators 28, 29, 30, and 31. That is, in the first embodiment, a detour path that guides to the second turn roller 25 by detouring the stranded wire S ′ twisted by the first turn roller 24 outward from the rotation axis M, and the third turn roller 26. In the second embodiment, the detouring path for detouring the stranded wire S ′ to which the twist is added from the rotation axis M and guiding it to the fourth turn roller 27 is partially guided only at both ends of the detouring path. The form differs from the first embodiment in that it guides the whole of both bypass routes.

  In the stranded wire machine 1A according to the second embodiment, the first arcuate rotating body 70 disposed so as to connect the first turn roller 24 and the second turn roller 25, the third turn roller 26, and the fourth A second arcuate rotating body 71 arranged to connect the turn roller 27 and a third arcuate rotating body 72 functioning as a dummy rotating body are provided.

  Inside each arcuate rotating body 70, 71, 72, a plurality of guide dies 701, 711, 721 for guiding twisted wires are arranged at a predetermined interval. In this strand wire machine 1A, the third arcuate rotating body 72 may be omitted, or two arcuate arcuate bodies corresponding to the first and second arcuate rotating bodies 70 and 71 are used. A rotating body may be provided. About another structure, it is substantially the same as the structure of the strand wire machine of the said embodiment.

  According to the stranded wire machine 1A according to the second embodiment, the same effects as the stranded wire machine 1 according to the first embodiment can be obtained. Moreover, according to this strand wire machine 1A, it replaces with the 1st thru | or 4th hook-shaped rotary body 28, 29, 30, 31 of 1st Embodiment, and the 1st and 2nd arcuate rotary bodies 70 and 71 are used. Therefore, the centrifugal force of the stranded wire S ′ itself in the detour path can be reduced by guiding the arcuate rotators 70 and 71, and the air resistance received by the stranded wire S ′ is also reduced by the arcuate rotator 70. , 71 can disperse the force applied to the stranded wire S ′ by the guide dies 701, 711, that is, can be applied to a soft stranded wire.

  FIG. 12 is a side view showing a stranded wire machine according to a third embodiment of the present invention. This stranded wire machine 1B is different from the stranded wire machine 1 of the first embodiment in that a plurality of guide rollers are used instead of the first to fourth saddle-like rotators 28, 29, 30, 31. That is, in the stranded wire machine 1B according to the third embodiment, the first to fourth plate-like members 80, 81, 82, 83 are used in place of the first to fourth hook-shaped rotating bodies 28, 29, 30, 31 respectively. The guide rollers 80a, 81a, 82a, 83a are rotatably supported as guide members at their tips. The first to fourth plate members 80, 81, 82, 83 are dummy rollers 80b for maintaining a balance during rotation at positions facing the mounting positions of the guide rollers 80a, 81a, 82a, 83a. 81b, 82b, 83b are rotatably supported. About another structure, it is substantially the same as the structure of the strand wire machine of the said embodiment.

  The stranded wire S ′ is hung on the first to fourth guide rollers 80a, 81a, 82a, and 83a, respectively. The stranded wire S ′ drawn from the first turn roller 24 is laid on the first guide roller 80a. Is suspended in the opposite direction to the first turn roller 24 (clockwise in FIG. 12). Further, a stranded wire S ′ drawn from the first guide roller 80a is hung on the second guide roller 81a in the same direction as the first guide roller 80a, and the third guide roller 82a has a third turn. The stranded wire S ′ drawn from the roller 26 is hung in the opposite direction to the third turn roller 26 (counterclockwise in FIG. 12). Further, a stranded wire S 'drawn from the third guide roller 82a is hung on the fourth guide roller 83a in the same direction as the third guide roller 82a.

  The first to fourth guide rollers 80a, 81a, 82a, 83a rotate the first to fourth rotating shafts 6, 7, 8, 9 and the first to fourth plate-shaped members 80, 81, 82, 83, respectively. Accordingly, it rotates around the rotation axis M.

  The twisting machine 1B according to the third embodiment is the same as the first embodiment in that only the both ends of the detour path are partially guided, but the guide is compared with the twisting machine 1 according to the first embodiment. Since the configuration of the members is simple, the configuration of the stranding machine 1B is simplified. Further, it is possible to reduce the resistance when the stranded wire S 'passes through the detour path.

  FIG. 13 is a side view showing a stranded wire machine according to a fourth embodiment of the present invention.

  The twisting machine 1C according to the fourth embodiment is different from the twisting machine 1 according to the first embodiment in that the driving source, the third rotating shaft 8 and the fourth rotation for the first rotating shaft 6 and the second rotating shaft 7 are used. The difference is that the drive source for the shaft 9 is separated. In the stranded wire machine 1 according to the first embodiment, the drive source of the first rotating shaft 6 to the fourth rotating shaft 9 is made common, and one motor 20 is provided as the driving source, but the third rotating shaft 8 In addition, since the rotation direction of the fourth rotation shaft 9 and the rotation direction of the first rotation shaft 6 and the second rotation shaft 7 must be reversed, the third rotation shaft 8 and the fourth rotation shaft 9 have a first differential, respectively. The device 10 and the second differential device 11 had to be provided.

  The stranding machine 1C according to the fourth embodiment is configured such that the drive source for the first rotary shaft 6 and the second rotary shaft 7 and the drive source for the third rotary shaft 8 and the fourth rotary shaft 9 are separated from each other. The differential device 10 and the second differential device 11 are not required, and the connection structure between the first rotation shaft 6 and the fourth rotation shaft 9 and the connection structure between the second rotation shaft 7 and the third rotation shaft 8 are simple. It is intended to make it easier. Hereinafter, different configurations will be briefly described.

  In the stranded wire machine 1 </ b> C, a motor 90 is provided in the cradle 12 as a driving source for the third rotating shaft 8 and the fourth rotating shaft 9, and the rotational force of the motor 90 is transmitted to the third rotating shaft 8 and the fourth rotating shaft by the transmission mechanism 91. It is configured to be transmitted to the rotary shaft 9.

  Although the detailed configuration of the transmission mechanism 91 is omitted, the rotational force of the motor 90 is once transmitted to the shaft 911 by the belt 912, and from the shaft 911 to the distal end portion of the third rotating shaft 8 by the belt 913 and the belt 914 (FIG. 13). Then, the transmission is transmitted to the left end) and the tip of the fourth rotating shaft 9 (right end in FIG. 13). The shaft 911 is rotatably supported at the distal ends of a pair of support members 92a and 92b (cradle) that are rotatably supported at the distal ends of the third rotating shaft 8 and the fourth rotating shaft 9.

  In addition, the motor 90 is supplied with power from the outside by wires provided on the second rotating shaft 7 and the third rotating shaft 8. Specifically, a slip ring 93 and a slip ring 94 are provided at positions near the right end of the second rotating shaft 7 and the left side of the second bowl-shaped rotating body 29, respectively. The two rotating shafts 7 are connected by a cable 96 passing through the inside. Further, a slip ring 95 is also provided at the tip of the third rotating shaft 8, and the slip ring 94 is connected to the slip ring 95 by a cable 97 passing through the inside of the third rotating shaft 8. Then, a three-phase alternating current is supplied from the outside to the slip ring 93, and the three-phase alternating current is supplied from the slip ring 95 to the motor 90 by a cable disposed along the cradle 12.

  The configuration of the transmission mechanism 91 of the stranding machine 1C according to the fourth embodiment is a transmission that transmits the rotational force of the motor 20 of the stranding machine 1 according to the first embodiment to the first rotating shaft 6 and the second rotating shaft 7. The configuration is the same as that of the mechanism. Therefore, the motor 90 is rotated in the opposite direction to the motor 20, whereby the third rotating shaft 8 and the fourth rotating shaft 9 rotate in the opposite direction to the first rotating shaft 6 and the second rotating shaft 7.

  As described above, in the fourth embodiment, the third rotating shaft 8 is directly rotatably supported by the support portion 702 of the second rotating shaft 7, and the tip end portion of the third rotating shaft 8 is transmitted by the belt 913. The fourth rotating shaft 9 is directly and rotatably supported by the support portion 602 of the first rotating shaft 6, and the tip end portion of the fourth rotating shaft 9 is connected to the shaft 911 of the transmission mechanism 91 by the belt 914. Since it becomes a structure which only connects, an apparatus structure can be simplified compared with 1st Embodiment.

  Needless to say, the configurations of the drive sources of the third rotating shaft 8 and the fourth rotating shaft 9 according to the fourth embodiment can be applied to the second and third embodiments.

  Of course, the scope of the present invention is not limited to the embodiment described above. For example, the path of the stranded wire in the stranded wire machine 1 of the first embodiment extends from the first turn roller 24 to the second turn roller 25 via the first rotator 28 and the second rotator 29 and is installed inside. The third turn roller 26 extends from the fourth turn roller 27 to the take-up bobbin 18 via the third rotating body 30 and the fourth rotating body 31. For example, a stranded wire supply reel is provided in the cradle 12. Further, it may be one that follows a path reverse to the above and reaches a winding bobbin disposed outside.

  Further, for example, in the first and fourth embodiments, the four rotating bodies for forming the detour path are substantially bowl-shaped, but the four rotating bodies are plate members, and a guide die is provided on each plate member. The structure provided at intervals may be sufficient. In the above embodiment, a gear is used for the differential device. However, a belt may be used.
