Embodiments of the present invention will be described in detail with reference to the following examples.
FIG. 1 is a perspective view showing a wire twisting device 2, and FIG. 2 is a view showing a part of the wire twisting device 2. In the figure, the direction a0 is the left-right direction of the wire twisting device 2, and i2 is the front-rear direction.

  The support base 30 includes a base base 31 and a support portion 32 that is fixed in an upright manner along the direction a0 on the rear side i02 of the top surface of the base base 31. The support base 30 further includes a support portion 33 on the front side i01. The support portion 33 includes a guide 34, a driving device 35, and an upper support plate 36.

  The guide 34 includes a pair of front and rear lower support plates 37 a and 37 b, a pair of left and right guide track members 38 a and 38 b, and a slide base 39. The pair of lower support plates 37a and 37b are arranged in parallel and fixed to the front side of the base 31 in an upright manner along the direction a0. The pair of guide track members 38a and 38b are installed in parallel between the lower support plates 37a and 37b. The slide table 39 is supported by the guide track members 38a and 38b so as to be movable back and forth. Vertical bar members 40a and 40b are erected on the left and right positions on the upper surface of the slide base 39, and the lower end horizontal portion 36a of the upper support plate 36 is fixed to the upper ends of the vertical bar members 40a and 40b. The driving device 35 is screwed into a servo motor 41 fixed to the upper surface of the base 31 and a front-rear female screw 39a at the center of the left-right width of the sliding base 39, and is rotatably installed between a pair of lower support plates 37a and 37b. And a screw shaft 42. A worm gear 43 is fixed to the output shaft 41a of the servo motor 41, and a wheel gear 44 is fixed to the front portion of the screw shaft 42, and both the gears 43 and 44 are engaged with each other. Thus, the support portion 33 displaces the upper support plate 36 to the front side i01 when the servo motor 41 rotates to the forward side, and displaces to the rear side i02 when it rotates to the reverse side.

  The support portion 32 and the support portion 33 each have a plurality of rotations (at least two are necessary and are required to rotate around the rotation center lines j1, j1, j1, and j1 that gradually approach each other toward the front side i01. The number of the hollow tubes 45 is four in a erected shape. Each hollow tube 45 includes a straight metal tube 46, and the center line of each metal tube 46 is aligned with the corresponding rotation center line j1.

  The support portion 32 is rotatably supported via a bearing 47 in a state in which the inclination displacement of each metal tube 46 is allowed. The bearing 47 supports each metal tube 46 in a state where movement in the front-rear direction is restricted. The upper support plate 36 of the support portion 33 rotatably supports the front portion of the hollow tube 45 through the corresponding bearing 48 while allowing the tilt displacement of the metal tube 46 to be allowed. The bearing 48 supports the metal tube 46 even in a state where relative displacement in the front-rear direction is allowed. For example, a self-aligning roller bearing can be used as the bearing 47 of the support portion 32, and the bearing 48 on the upper support plate 36 is, for example, a sliding in the center line direction of the metal tube 46 in addition to the self-aligning roller bearing. An appropriate sliding bearing for guiding the displacement can be used.

  Each metal tube 46 is provided with a sliding body 51 and a pull-out rod 49 that are fitted onto a part of the outer peripheral surface thereof. Corresponding to the drawing rod 49, an opening 46a is formed at a location between the support portion 32 and the support portion 33 in the middle of the length of each metal tube 46.

  Each pull-out rod 49 includes a rod 50 and a link 52 that are positioned so as to cover the corresponding opening 46a. The rod 50 and the link 52 are arranged in series in the length direction of the metal tube 46 and are pivotally connected. ing. An annular portion 53 is formed on the inner surface portion of the rod 50. Each rod 50 has a groove shape that is fitted on the outer peripheral surface of the corresponding metal tube 46, and has a size that can cover the entire corresponding open portion 46 a. Each sliding body 51 is externally fitted to the corresponding metal tube 46 so as to be slidable. Each sliding body 51 slides on the outer periphery of the metal tube 46 as the upper support plate 36 changes in the a0 direction, and rotates in the same shape as the metal tube 46. The front end portion of each rod 50 is connected to the rear end portion of the corresponding sliding body 51 via a spring hinge 54, and each rod 50 is against the elasticity of its corresponding spring hinge 54. The tip is oscillated and displaced outward. Each link 52 is formed of a straight strip member, and one end portion is pivotally connected to a portion near the center of the length of the corresponding rod 50 via a pin 55 and the other end portion is a corresponding metal tube. It is pivotally connected to 46 via a pin 56. A balance weight 57 is fixed to the other end of each link 52.

  Each pull-out rod 49 converts the longitudinal movement of the sliding body 51 into the movement movement in the diameter direction of the annular portion 53 around the rotation center line j1 by the pivotal connection of the spring hinge 54, the pin 55, and the pin 56. .

  Each annular portion 53 is formed by bending a small diameter member into a U shape, and is fixed to the inner surface of the rod 50. Each annular portion 53 is located at a position where the rod 50 is parallel to the length direction of the metal tube 46 and completely covers the open portion 46 a, and the U-shaped curved outer periphery is the inner hole inner periphery of the metal tube 46. Touch along the surface.

  When the upper support plate 36 of the support portion 33 is positioned at the reference position m0 (the frontmost position) shown in FIG. 2, each pull-out rod 49 has a sliding body 51, a rod 50, and a link as shown in FIG. 2A. 52 is stretched along the metal tube 46 with the pin 56 as a fulcrum. At this time, the rotation center line j1 passes through the position of the opening of the annular portion 53. Further, when the outer periphery of the U-shaped curved surface of the annular portion 53 is in contact with the inner peripheral surface of the inner hole of the metal tube 46, the insertion wire W 1 is inserted between the metal tube 46 and the annular portion 53. It is not caught in.

  On the other hand, as shown in FIG. 2B, when the upper support plate 36 is displaced from the reference position m0 to the rear side i02 by a distance i3, the rod 50 and the link 52 have the pin 56 as a fulcrum and the spring hinge 54 and the pin 55 It becomes a state triggered as a pivot point. The outer periphery of the U-shaped curved surface of the annular portion 53 deviates from the rotation center line j 1 and reaches the outside of the metal tube 46.

  An electric motor 58 as a driving device for rotating each hollow tube 45 is fixed to the upper surface of the base 31 between the support portion 33 and the support portion 32 in the front-rear direction. On the other hand, a large-diameter gear 59 is mounted at a position near the center of the rear surface of the support portion 32 so as to be rotatable about a front-rear direction line and is interlocked with the output shaft of the electric motor 58.

  And the former side edge part of each metal tube 46 protrudes further back from the support part 32, and the small diameter gearwheel 60 is being fixed to the outer peripheral surface location. Each small-diameter gear 60 is simultaneously meshed with the large-diameter gear 59 and simultaneously transmits the rotation of the output shaft of the electric motor 58 to the corresponding hollow tube 45. Thereby, each metal tube 46 rotates in the same direction.

  Next, the usage example and effect | action of the wire twisting apparatus formed as mentioned above are demonstrated.

  First, the covered electric wire w1 is guided to the hollow tube 45 of the wire rod twisting device 2. When this processing is performed, the servo motor 35 is operated as necessary, so that the rod 50 of the extraction rod 49 is in the state shown in FIG. 2A. The covered electric wire w1 is inserted into the opening k1 of the metal tube 46. At this time, the covered wire w <b> 1 passes through the U-shape of the annular portion 53 and then reaches the front side of the wire twisting device 2 through the front end opening of the metal tube 46. As a result, the covered electric wire w <b> 1 is guided to the hollow tube 45.

  Next, the covered electric wire w <b> 1 guided by each hollow tube 45 is pulled forward, and its tip is entangled with fingers.

  Then, by operating a switch on an operation panel (not shown), the servo motor 41 is rotated by a necessary amount corresponding to the degree of twisting of the covered wire w1. The servo motor 41 displaces the slide base 39 to the rear side i02 via the front / rear guide mechanism 34, and displaces the rod 50 of the extraction rod 49 to the state shown in FIG. 2B. As a result, the annular portion 53 moves in conjunction with each other and is separated from the rotation center line j1 of the metal tube 46.

  The position of the annular portion 53 is stably maintained by a self-locking function of the worm gear 43 and the wheel gear 44 and a braking function by a brake means incorporated in the servo motor 41. Thereafter, the electric motor 58 of the wire rod twisting device 2 is operated.

  The rod 50 and the link 52 constituting the pull-out rod 49 are inclined and rotate together with the metal tube 46 in a state of protruding from the metal tube 46 so as to be separated from the rotation center line j1. Since all the extraction rods 49 provided in any metal tube 46 rotate at the same phase, the extraction rods 49 do not collide with each other even though the intervals between the plurality of metal tubes 46 are relatively narrow.

  In such a relationship between the covered electric wire w1 and the hollow tube 45, the annular portion 53 of the drawing rod 49 passes through the corresponding open portion 46a of the metal tube 46 and the covered electric wire w1 inserted into the metal tube 46. It is bent into a mountain shape on the corresponding hollow tube 45. As a result, the covered wire w1 is given a twisting force in the same direction as the rotation of the hollow tube 45 during rotation of the hollow tube 45 from the corresponding drawing rod 49. That is, the more the slide body 51 is displaced rearward by the servo motor 41, the more the rod 50 rises, and the annular portion 53 is separated from the rotation center line j1 of the metal tube 46. Thereby, the resistance given to the covered electric wire w1 which passes the inner side of the annular part 53 becomes large, and the covered electric wire w1 is pulled by rotation of the hollow tube 45, and a strong twist is given. As a result, the covered electric wires w1 coming out of the hollow tube 45 are twisted together at a short pitch.

  Each covered electric wire w1 to which the above-described twist is applied reaches the front side of each hollow tube 45 in a state of being twisted. The plurality of covered electric wires w1 that have reached here are entangled with each other by their own twists and twisted into a single wire to form a wire w2.

The tube holding portion 11 is positioned horizontally above the rear portion 2b of the wire twisting device 2 and is fixed to the vertical surface portion 1B of the assembly stand 1.

  In the lower part 1 </ b> C located on the lower side of the wire twisting device 2, a long twisted wire housing portion 13 for housing the twisted wire w <b> 2 fed from the front portion 2 a of the wire twisting device 2 is provided. The long stranded wire accommodating portion 13 includes a stranded wire discharge guide tube 14 and a container 15.

  Returning to FIG. 3, a short wire supply guide 20 is provided on the right side of the wire twisting apparatus 2 on the right side of the drawing. The short wire supply guide pipe section 20 is connected in parallel with the same number of wire straight insertion tubes 21 as the wire supply position d1 via a U-shaped support plate 22a and two rectangular connecting plates 22b. Each straight wire insertion tube 21 has a double tube structure that can be expanded and contracted, and is, for example, about a few tens of centimeters in the extended state, and the diameter of the inner hole is about several times that of the wire w1. . A central surface portion e1 of the U-shaped support plate 22a is installed so as to be swingable about a horizontal rotation center line a2 orthogonal to the vertical surface portion 1B of the assembly stand 1 via a support mechanism (not shown). The short wire supply guide pipe portion 20 is fixed in any one of two states by swinging around the horizontal rotation center line a2. One of the two states is a non-use state in which each wire rod straight insertion tube 21 is in a vertical posture as shown in FIG. 3, and the other is each wire rod straight insertion tube 21 as shown in FIG. Is a state of use in which a horizontal posture is assumed. In the state of use, the front opening 21a of each wire rod straight insertion tube 21 is directly opposed to the corresponding wire rod supply position d1 in the horizontal direction.

  In the wire stranding device 2 in the lateral orientation, the short twisting for continuously accommodating the single wire twisting wire w2 sent out from the front part 2a is provided on the front part 2a side which is the twisting wire sending side. A line accommodating portion 23 is formed. The short stranded wire accommodating portion 23 includes a container 24 and a support mechanism 25 for the container 24. A rotation sensor 24 a detects the rotational displacement of the container 24. The container 24 has a structure that conforms to the container 15 of the long twisted wire housing portion 13, and is formed of a horizontal cylindrical body 25, an annular plate 26, and a circular plate that forms a bottom surface 27. The bottom surface 27 of the container 24 is disposed orthogonal to the left-right direction a0 and is supported by the left end surface 1a of the vertical surface portion 1B of the assembly stand 1 via a support mechanism 25. The support mechanism 25 includes a support arm 25a that is swingably mounted about a left-right direction line a3, and a bottom surface 27 is rotatably mounted on a front portion of the support arm 25a about a left-right direction line a4.

That is, one is a state in which the container 24 faces the front part 2a of the wire twisting device 2 in the left-right direction a0. The other is a state in which the container 24 is moved to a position h1 as shown in FIG. 6 and completely deviated from the range facing the front portion 2a of the wire twisting device 2, for example.

  In FIG. 3, the wire twisting device 2 is in a state in which the outer periphery of the entire components on the base 31 is covered with the box-shaped cover 16 shown in FIG. 3.

Only the rotation is supported on the rear surface of the surface portion 1B. The speed change mechanism 65 is for changing the rotation speed ratio between the lower vertical axis 63 and the upper vertical axis 64, and the rotation speed ratio is arbitrarily changed by operating an input member (not shown). Yes. The electric motor 62 and the lower vertical axis 63 are interlocked and connected via a belt transmission mechanism 68.

  The lower belt transmission portion 66 interlocks and connects the lower end portion of the lower vertical axis 63 and the vertical rotation shaft 19 to which the container 15 is fixed. On the other hand, the upper belt transmission portion 67 interlocks and connects the hollow tube 5 to which the vertical container 4 is fixed and the upper portion of the upper vertical axis 64. Thus, the vertical container 4 and the container 15 are rotated at an arbitrary rotational speed.

  Next, the usage example and effect | action of the wire twisting apparatus 2 formed as mentioned above are demonstrated.

  Here, the wire w1 as a processing target is a covered electric wire, and the case where the long covered electric wire w1 is processed and the case where the short covered electric wire w1 is processed will be described separately.

<When processing a long covered electric wire w1>
As shown in FIG. 3, the wire twisting device 2 is fixed in a state in which the front portion 2a thereof is directed downward. And the short wire supply guide pipe part 20 is set in a state in which the wire guide direction is vertical and does not protrude laterally from the right end of the assembly stand 1, and the short twisted wire housing part 23 is laterally moved as necessary. Move it around the line and fix it in a position that does not interfere with the work.

  The winding bundle w0 of the covered electric wire w1 is accommodated inside each longitudinal container 4 of the long wire supply part 3. At this time, the wire rod longitudinal guide tube 6 is removed from the hollow tube 5 upward. Then, the wire rod longitudinal guide tube 6, the arm member 7, the wire rod guide pulley 8 and the guide rod member 9 are moved to a position where there is no hindrance while being integrated. Under this state, the winding bundle w0 in a horizontal posture is inserted from directly above each vertical container 4 and is externally fitted to the plurality of positioning rod members 4d, and placed concentrically on the bottom surface 4b of the vertical container 4. . Thereafter, the wire rod longitudinal guide tube 6, the arm member 7, the wire rod guide pulley 8 and the guide rod member 9 are restored to their original positions.

  And the process which guides the corresponding covered electric wire w1 for every site | part corresponding to each vertical container 4 is performed. That is, the coated wire w1 of the winding bundle w0 in the vertical container 4 is unwound and inserted into the annular portion 9a at the distal end of the guide rod member 9 from the distal end side thereof, leading upward, and the outer circumferential groove on the upper half side of the wire guide pulley 8 Let me guide you. Subsequently, it is led downward and inserted into the inner holes of the wire rod longitudinal guide tube 6, the hollow tube 5 and the wire guide flexible tube 10 so as to be inserted from above, through the base 12 fixed to the tube holding plate 11. Guide to the bottom.

  Next, the covered wire w1 thus guided is guided to the wire supply position d1 and guided to the hollow tube 45 of the wire twisting device 2. The ends of the covered wires w1 that have emerged from the wire twisting device 2 are entangled in a single line under the twisted wire discharge guide tube 14 and fixed in the container 15.

  Thereafter, the electric motor 58 of the wire twisting device 2 is operated, and the electric motor 62 of the container driving means 61 is operated.

  On the other hand, the container 15 of the long stranded wire accommodating portion 15 is opened through the lower vertical axis 63 and the lower belt transmission portion 66 by the rotation of the electric motor 62, and the lower vertical axis 63, the transmission mechanism portion 65, and the upper side are opened. The container 4 is rotated through the belt transmission portion 67 and the hollow shaft 5. At this time, the rotational speed change function by the speed change mechanism 65 makes the rotational speed of the container 4 somewhat higher than that of the container 15. The length in which the plurality of covered electric wires w1 are twisted to form a single wire by the wire twisting device 2 is moved in the length direction of each covered electric wire w1 because each of the covered electric wires w1 twisted is transformed into a spiral shape. This is because it becomes shorter than the amount.

  When it is desired to change the twisting pitch of the twisting wire w2, the operator operates the switch on the operation panel (not shown) to rotate the servo motor 41 in any direction. At this time, when it is desired to increase the twisting pitch, the servo motor 41 is rotated to the positive side. As a result, the upper support plate 36 is moved to the front side i01, and the annular portion 53 of the extraction rod 49 is displaced so as to approach the rotation center line j1 of the corresponding metal tube 46. As a result, the twisting force applied to the corresponding covered wire w1 is reduced, and the twisting pitch is increased. Conversely, when it is desired to reduce the twisting pitch, the servo motor 41 is rotated in the reverse direction. As a result, the upper support plate 36 is moved to the rear side i02, and the annular portion 53 of the extraction rod 49 is displaced away from the rotation center line j1 of the corresponding metal tube 46. As a result, the twisting force applied to the corresponding covered wire w1 is increased, and the twisting pitch is reduced.

  Further, the rotational speed of the hollow tube 45 is adjusted by changing the twisting pitch of the twisted wire w2 or by the difference in properties of the covered wire w1.

<When processing a short covered wire w1>
As shown in FIG. 6, the wire twisting device 2 fixes the front part 2a to the left side. And the short wire supply guide pipe part 20 moves the support mechanism 25 by manual operation, and is located just beside the left side of the twisted wire discharge guide pipe 14.

  After this, a large number of short covered electric wires w1 having a length of about 10 m or less are prepared, inserted into the respective straight wire insertion pipes 21 of the short wire supply guide pipe portion 20 from the rear end openings k1, and each straight wire is straight. It passes through the insertion tube 21 and reaches the left outer side of the front end opening. Thereafter, the tip of each covered electric wire w1 is pulled and moved to the wire rod supply position d1 that is present on the left side of each wire rod straight insertion tube 21. Then, each of the covered electric wires w1 that have been pulled and moved is guided to each hollow tube 45 of the wire rod twisting device 2 to reach the front side of the wire rod twisting device 2 in the same manner as described above. The inside of the discharge guide tube 14 is passed. The tips of the plurality of covered electric wires w1 are tangled in a single wire by hand. Then, the servomotor 41 of the wire rod twisting device 2 is actuated as necessary so that the twisting force applied by the pulling rod 49 is set to an appropriate magnitude. Thereafter, the electric motor 58 is operated. As a result, the short covered wire w1 is twisted between the front portion 2a of the wire twisting device 2 and the twisted wire discharge guide tube 14 in accordance with the case of the long covered wire w1 to form a twisted wire w2. Then, it is gradually moved to the left side a01 and supplied to the inside of the container 24 through the circular through hole of the annular plate 26.

  When the stranded wire w2 is supplied to the container 24, the stranded wire w2 is pushed down while being appropriately restrained from being deformed by its own rigidity while hanging down due to gravity. As a result, the twisted wire w2 is deformed and accumulated in a roll shape while rotating the rotatable container 24 around the left-right direction line a4.

  The rotation sensor 24a detects the rotational displacement of the container 24 that is accommodating the twisted wire w2. Based on this detection amount, the formation amount of the stranded wire w2 with respect to the feed amount of the coated wire w1 can be detected. Using this relationship, the relationship between the rotation amount of the container 4 and the rotation amount of the container 15 when processing the above-described long covered electric wire w1 can be set in the rotation speed changing function by the transmission mechanism unit 65.

  In the previous embodiment, the posture of each pull-out rod 49 is determined by the back-and-forth movement of the sliding body 51. FIG. 7 shows an embodiment in which this is performed manually.

  The hollow tube 45 in this embodiment is divided into front and rear metal tubes 146b and 146c, and is connected in a line by a plate 146d. The plate 146d holds the metal tubes 146b and 146c by making a half turn around the outer periphery of the metal tubes 146b and 146c. In addition, the plate 146d has a portion 146e extending in the outer tangent direction of the metal tubes 146b and 146c. The portion 146e is provided with a shaft 156 that pivots the rod 156, and an arc-shaped slit 146f that is centered on the shaft 156. The slit 146f is provided with a pin 155 that can be fixed at any position. In the figure, the pin 155 is shown fixed to the top of the slit 146f. The rod 149 has a slit 149a that slides in the length direction of the shaft 156, and a spring 149b that constantly biases the pin 155 to one side is incorporated in the slit 149a. At the other end of the rod 149, a groove 149c for hooking on the pin 155 is provided. A balancer 157 is provided on the opposite side of the rod 156, and the weight is adjusted so that the center of gravity comes to the center of rotation when the metal tubes 146b and 146c are rotated.

  The annular portion 153 is obtained by bending a small diameter member into a U shape, and is fixed to the inner surface of the rod 149. Each annular portion 153 is located at a position where the rod 149 covers the open portion 146a in parallel with the length direction of the metal tubes 146b, c (FIG. 8A), and the U-shaped curved outer periphery is the inner periphery of the plate 146d. Touch along the surface. At this time, the rotation center line j1 passes through the position of the opening of the annular portion 153.

  On the other hand, in order to separate the annular portion 153 from the rotation center line j1, the rod 149 is pulled up around the shaft 156 (FIG. 8B), and the spring 149b is compressed. Thereafter, the spring 149b is released and hooked on the pin 155 in the groove 149c. In conjunction with the movement of the rod 149, the annular portion 153 is separated from the rotation center line j1.

  Next, an example of use and operation of the rod 149 as described above will be described. First, the rod 50 of the rod 149 is set to the state shown in FIG. 8A. The covered electric wire w1 is guided to the metal tube 146c. The covered electric wire w1 passes through the U-shape of the annular portion 153 and then reaches the front end opening of the metal tube 146b. Then, the rod 149 is hooked on the pin 155. As a result, the annular portion 153 is separated from the rotation center line j1 of the metal tubes 146b and c. The position of the pin 155 is determined in advance corresponding to the twist pitch. After that, as in the above-described embodiment, by rotating the small diameter gear 60 fixed to the hollow tube 146c and rotating the metal tubes 146b and c, the covered electric wires w1 are mutually twisted by their twists. It is entangled and twisted into a single wire.

The above-described embodiment and its use example may be modified as follows.
That is, the number of the vertical accommodating cylinders 4 of the long wire supply part 3 may be at least two, and the number of the covered wires w1 to be twisted at this time is from two to the number of the vertical containers 4. It becomes the range. When three or more vertically oriented containers 4 are provided, at least two of the winding bundles w0 are accommodated, whereby the stranded wire w2 can be obtained with respect to the two or more covered electric wires w1.

  The sliding body 51 may be positioned at a different position on the metal tube 46, for example, between the open portion 46a and the support portion 32. In this case, the upper support plate 36 does not need to be displaced back and forth, but in order to displace the slide body 51 back and forth, a support plate 36 that can be displaced back and forth between the slide body 51 and the support portion 32 is used. It is necessary to provide it.

  In the embodiment, the rod 50 is disposed on the rear side of the link 52, but this positional relationship may be reversed.

  Further, the object to be processed may be not only the covered electric wire w1 but also other wires, fibers, tubes, etc. However, in the material having a small frictional resistance with the annular portion 53, the rotation of the straight tube member does not propagate and the twist is not applied. Therefore, resin is desirable.
