As an example, twist one end of each of the two wires inside the cylindrical portion and feed it toward the other end with a driving roller. As an example, the intermediate rotor is the same as twisted. It describes that the two wires are twisted together by rotating in the direction.

  In Patent Document 3, one electric wire clamp is driven to rotate by a drive unit, the other electric wire clamp is fixed, and the one end-side electric wire clamp and the other end-side electric wire clamp are intermittent in a direction crossing the opposing direction. In order to move forward, it is described that an attachment station for attaching the electric wire to the electric wire clamp is set at the upstream end, and a removal station for removing the twisted electric wire from the electric wire clamp is set at the downstream side.

  1 and 2 show an embodiment of a twisted wire manufacturing apparatus according to the present invention.

  As shown in FIG. 1, the twisted wire manufacturing apparatus 1 includes first intermittent rotations having clamps 3 for fixing one end (A end) 2 a of a pair of electric wires 2 (FIG. 2) on three circumferential surfaces 7 to 9. The body 4, a pair of clamps 5 that fix the other end (B end) 2 b of the pair of electric wires 2, and a motor 6 that rotates the electric wires 2 integrally with the clamp 5 are respectively provided on the three circumferential surfaces 10 to 12. The second intermittent rotating body 13 is provided.

  In FIG. 1, each surface 7, 10 in front of each intermittent rotating body 4, 13 is an electric wire set surface, each lower surface 8, 11 is a wire pair twist (twisted) processed surface, and each inner surface 9, 12. Is the twisted wire tape winding / dispensing surface. Each intermittently rotating body 4 and 13 is intermittently rotated counterclockwise (counterclockwise) by 1/3 turn in the circumferential direction as indicated by arrow A, and the wire setting surfaces 7 and 10 are moved to the wire pair twisting surfaces 8 and 11. The wire pair twist surfaces 8 and 11 are moved to the tape winding / dispensing surfaces 9 and 12, and the tape winding / dispensing surfaces 9 and 12 are moved to the electric wire setting surfaces 7 and 10.

  The first intermittent rotating body 4 is formed by cutting three apexes of equilateral triangles into short side end faces 14a and 15a, and three long side end faces 14b and 15b between the three short side end faces 14a and 15a as mounting surfaces. The front and rear vertical plate portions 14 and 15, the front and rear long side end surfaces 14 b and 15 b, the substrates 16 fixed to the front and rear long side surfaces 14 b and 15 b, and the clamps 3 arranged on the surface (outer surface) side of the substrates 16 Yes. Each substrate 16 forms a part of three sides of an equilateral triangle, the crossing inner angle of the extended surface of each substrate 16 is 60 °, and the length and width dimension in the front-rear direction of each substrate 16 are the same. The lower (twisted surface) substrate 16 is positioned horizontally, and the upper left and right (wire setting surface and payout surface) substrates 16 are inclined at an internal angle of 60 °.

  As shown in FIG. 2, the clamps 3 are arranged separately on the left and right or top and bottom so as to fix the ends 2 a of the two wires 2 separately for each wire 2. Each clamp 3 advances the lever 3a to open the groove 3c of the block 3b with a wedge member integral with the lever 3a, inserts the electric wire 2 into the groove 3c, and then retracts the wedge member integrally with the lever 3a. The groove 3c is closed by the force of the coil spring 3d to press (clamp) and fix the electric wire 2. In FIG. 2, the groove 3c is opened (FIG. 2 shows a state in the middle of setting the electric wire 2). Terminals 2a and 2b of the electric wire 2 are crimped and connected to the terminals 2 and are accommodated in the wide part of the groove 3c.

  In FIG. 2, reference numeral 17 denotes a short air cylinder for releasing the clamp 3, and 18 denotes a long air cylinder that moves the clamp 3 forward and backward and applies a back tension (tensile force) to the electric wire 2. A movable substrate (substitute with reference numerals 7 to 9), to which the clamp 3 is fixed, is slidably engaged with a horizontal rail 19 in the front-rear direction of the substrate 16. The rod 18a of the long cylinder 18 is connected to the movable substrates 7 to 9, and the back tension is applied to the electric wire 2 in the compressed state of the cylinder 18 of FIG. These cylinder mechanisms will be proposed separately.

  The clamp 3 is not limited to this example, and any clamp can be used as long as the end 2a of the electric wire 2 is gripped and fixed. It is also possible to have a structure in which the end portions 2a of the two electric wires 2 are clamped integrally and the back tension is applied integrally. When the tension cylinder 18 is not used, the clamp 3 can be provided on the fixed substrate 16. In this case, the board | substrate 16 becomes an electric wire set surface.

  A plate portion 15 on the proximal end side of the first intermittent rotating body 4 is connected to a central horizontal shaft portion, and the shaft portion is connected to a shaft portion of a torque brake (torque clutch) 21 at the upper end of the vertical column 20 in FIG. Subsequently, the upper end of the rod of the upward air cylinder 23 is rotatably connected to the shaft portion via the link 22, and the lower end of the air cylinder 23 is rotatably supported and fixed to the support column 20. At least the air cylinder 23 and the torque brake 21 constitute drive means. The air cylinder 23 and the torque brake 21 are commercially available.

  For example, the torque brake 21 is released from the state of FIG. 2 (the clutch is disengaged), the air cylinder 23 is extended with a collar (the first intermittent rotating body does not rotate), the torque brake 21 is activated (the brake is applied and the clutch is As the air cylinder 23 is compressed, the first intermittent rotating body 4 rotates counterclockwise by 1/3 turn (at an internal angle of 120 °). When a rotation control mechanism is installed in the torque brake 21, rotation is possible without releasing the brake. The same applies to the second intermittent rotating body 13 described later. These intermittent rotational movements can be performed by an air actuator or the like without depending on the torque brake 21 and the air cylinder 23. The first intermittent rotating body 4 is slidable back and forth on a horizontal rail of an apparatus base (not shown) according to the set length of the electric wire 2.

  As shown in FIGS. 1 and 2, the second intermittent rotator 13, like the first intermittent rotator 4, has three side end faces 24 a and 25 a that form part of three sides of an equilateral triangle, and each side. Front and rear plate portions 24, 25 having side end surfaces 24b, 25b between the end surfaces 24a, 25a, and three substrates (reference numerals 10 to 10) connecting the three side end surfaces 24b, 25b of the front and rear plate portions 24, 25. 12), a short support 27 standing on the surface (outer surface) of each of the substrates 10 to 12, a motor 6 fixed to each support 27, and left and right fixed to the shaft body of the motor 6 so as to be rotatable. Or a pair of upper and lower clamps 5 are provided. In the specification, for convenience, the second intermittent rotating body 13 side will be described as the front, and the first intermittent rotating body 4 side will be described as the rear.

  A pin portion (switch) 28 composed of a horizontal shaft 28 a and a vertical small-diameter disk-shaped head portion 28 b is provided on the front surface of the short column 27 so as to project, for example, the shaft 28 a penetrates the column 27 and passes through the motor 6. When the motor 6 is positioned at the lowermost part, that is, the wire pair twisting surface 11, the hook-like member at the tip of the horizontal short air cylinder 30 provided on the rear surface of the long vertical column 29 at the front is connected. The head 28 b is engaged with the horizontal groove 31 a of 31, and the motor 6 is turned on and off by the expansion and contraction of the air cylinder 30.

  Each pair of clamps 5 has, for example, a block in a cylindrical portion 5b having a horizontal groove 5a and an orthogonal lever 5c that opens and closes the block, and the electric wire is clamped and fixed in the groove 5a by an advance / retreat operation of the lever 5c. It is something to be made. The B end 2b of the pair of electric wires 2 is set to the pair of clamps 5 on the electric wire setting surface 10 on the near side in FIG. The clamp 5 is not limited to this, and any clamp can be used as long as it can grip and fix the end of the electric wire 2. The pitch between the pair of clamps 5 is larger than the pitch between the pair of clamps 3 of the first intermittent rotating body 4, and the pair of electric wires 2 is set to be slightly inclined in a taper shape. This is to make it easier to insert a pair of twisted bars 33 of a rotor 32 (FIG. 3) described later between the pair of electric wires 2.

  A shaft portion is provided at the center of the front plate portion 24. The shaft portion is connected to the shaft portion 34a of the front torque brake 34, and a vertical air cylinder 36 is connected via a link 35 fixed to the shaft portion 34a. The lower end of the air cylinder 36 is fixed to the support column 29 by a bracket 37 so as to be swingable. Similar to the first intermittent rotating body 4, the second intermittent rotating body 13 is counterclockwise by the operation of the torque brake 34 and the air cylinder 36. It is intermittently rotated around. The intermittent rotor 13 is locked by a brake operation of the torque brake 34. The driving of the front and rear intermittent rotating bodies 4 and 13 and the driving of the air cylinders 23, 236, 24, 17 and 18 are performed via a control unit (not shown).

  At least the air cylinder 36 and the torque brake 34 constitute drive means. Instead of the torque brake 34, an air-type intermittent actuator can be used. When the rotation of the intermittent rotating body 13 by the air cylinder 36 is stopped, it is preferable to absorb the impact with a hydraulic damper.

  The wire 2 in FIG. 2 is actually set longer, the intermittent rotors 4 and 13 are greatly separated in the front-rear direction, and a pair of twisted bars (twisted portion) of the rotor 32 in FIG. 33 is penetrated, and the rotor 32 rotates in this state, and at the same time, the motor 6 in FIG. 2 rotates in the same direction as the rotor 32 at the same rotation speed, so that the counter-twisted rod of the rotor 32 as shown in FIG. The electric wire 2 is twisted between 33 and the clamp 3 of the first intermittent rotating body 4 of FIG.

  As shown in FIG. 3, the rotor 32 of this example is formed in a circular ring shape, and has a notch opening 32a in a part of the circumference. The notch opening 32a communicates with a wide inner diameter portion (inner space) 32b. A twisted rod (twisted portion) 33 is erected on the inner diameter portion facing the opening 32a, has a gear portion 38 on the outer peripheral portion, and the gear portion outside the timing belt 39 meshes with the gear portion 38. The gear portion inside the belt 39 is driven by a gear 41 following the motor 40. The rotor 32 is lifted and lowered by a vertical air cylinder 42 integrally with the belt 39 and the motor 40, and the pair of electric wires 2 enter the left and right sides of the twisted bar 33 when the rotor 32 is lifted. When the rotor 32 is stopped, the notch opening 32a is positioned on the upper side. The rotor 32, the motor 40, the timing belt 39, the air cylinder 42 and the like constitute a rotor unit 43.

  A horizontal substrate 44 provided with an air cylinder 42 is slidably engaged with a rail (not shown) in the front-rear direction on the lower side of the apparatus by a slide portion 45, and the rotor 32 rotates and is not shown along the rail at the same time. The drive means (for example, a ball screw) advances toward the second intermittent rotating body 13. In FIG. 3, reference numeral 46 denotes a guide roller, 47 denotes a driven gear, and 2 'denotes an electric wire twist portion. A gear may be used instead of the timing belt 39.

  In this example, an example using the rotor 32 will be described. For example, without using the rotor 32, the motor 6 of the second intermittent rotating body 13 is rotated in the state of FIG. It is also possible to do. Although the total length of the electric wire 2 is shortened by twisting, excessive tension can be prevented by loosening the back tension by adjusting the pressure of the long cylinder 18 of the first intermittent rotating body 4 weakly.

  As shown schematically in FIG. 4A, the rotor 32 rotates in the direction of the arrow, and the twisted rod 33 twists the pair of electric wires 2 inside the rotor 32, as shown in FIG. 4B. A twist line 2 'is formed. In FIG. 4A, reference numerals 3 and 5 denote front and rear clamps, and in FIG. 4B, reference numeral 48 denotes a terminal. For example, in FIG. 4A, the electric wire 2 is twisted only by rotating the rotor 32 without moving the rotor 32 back and forth, and the motor 6 of the second intermittently rotating body 13 in FIG. It is possible.

  An example of the operation of the twisted wire manufacturing apparatus and the twisted wire manufacturing method will be described below with reference to the flowchart of FIG.

  First, when starting the apparatus 1, an operator takes out the two electric wires 2 in step 1 of FIG. 5, and in step 2, the A end (one end) 2a of each electric wire 2 is rotated first intermittently in FIG. The electric wire set surface 7 on the upper side of the body 4 is held and fixed to each clamp 3. Next, in step 3, the operator moves to the B end 2 b side of the electric wire 2, that is, to the second intermittent rotating body 13 side. In step 4, the B end (other end) 2 b of each electric wire 2 is moved to the second intermittent rotating body 13. Are gripped and fixed to the respective clamps 5 on the electric wire setting surface 10 on the upper side. Next, in step 5, the operator pulls the levers (for example, links 22 and 35) on the upper sides of the intermittent rotating bodies 4 and 13 downward to rotate the intermittent rotating bodies 4 and 13 by 1/3. At this time, the pressures of the torque brakes 21 and 34 and the air cylinders 23 and 36 are released. Each electric wire set surface 7, 10 moves to the lower electric wire pair twist surface 8, 11. Steps 1 to 5 are steps performed by an operator.

  Next, at step 6, the rotor 32 (FIG. 3), the motor 40, etc. are moved up by the cylinder 42 and positioned close to the rear of the clamp 5 on the counter-twisted surface 11 of the second intermittent rotating body 13 (FIG. 2). At this time, since each electric wire 2 is opened in a tapered shape as shown in FIG. 2, the twisted rod 33 of the rotor 32 is reliably inserted between the electric wires 2. Next, at step 7, the rotating surfaces 7-9, 10-12 of the intermittent rotating bodies 4, 13 are automatically locked. Locking is performed by the braking operation of the torque brakes 21 and 34. Next, in step 8, the rotor 32 automatically moves from the B end 2b of the electric wire 2 to the A end 2a, that is, from the second intermittent rotating body 13 side to the first intermittent rotating body 4 side. Next, in Step 9, the rotor 32 moves from the A end 2a to the B end 2b while rotating, so that twist processing is automatically performed.

  Next, at step 10, the rotor 32, the motor 40 and the like are lowered by the cylinder 42 and automatically separated downward before the clamp 5 of the second intermittent rotating body 13. Next, in step 11, the lock of the rotating surface of each intermittent rotating body 4, 13 is automatically released. That is, the braking of the torque brakes 21 and 34 is released (when the rotation control mechanism is installed, it is not necessary to release the brake). In this state, the intermittent rotating bodies 4 and 13 are automatically rotated counterclockwise by 1/3 at step 12, and the lower wire pair twist surfaces 8 and 11 are placed on the back tape winding / dispensing surfaces 9 and 12. Moving.

  Next, at step 13, the B end of the twisted wire 2 ′ is automatically wound on the tape winding / dispensing surfaces 9, 12. The tape winding machine (not shown) has, for example, a single-sided adhesive tape, a tape guide, a cutter, and a forward / backward cylinder, and presses the tape stretched in a U shape along the tape guide against the B end of the twisted wire 2 '. Glue and cut with a cutter. The tape winding machine can reciprocate between the A end and the B end, and tapes the B end while moving to the B end side. Next, the tape winding machine moves away from the B end and moves to the A end side. In step 14, the A end of the twisted wire 2 'is automatically tape-wrapped, and then separated from the A end. Next, the twisted wire (product) 2 'completed in step 15 is paid down and dropped to the finished product storage area.

  The payout of the twist line 2 'is performed by, for example, an automatic payout machine (not shown). The automatic dispenser includes, for example, a pair of front and rear chucks that move toward the twist line 2 ′ of the dispensing surfaces 9 and 12 using front and rear air cylinders that are obliquely upward, and a vertical air cylinder that raises and lowers the chucks. When the twisted wire 2 ′ is transferred to the chuck, the clamps 3 and 5 of the intermittent rotating bodies 4 and 13 are released by pushing the levers 3 a and 5 c with the air cylinder 17. Instead of using an automatic dispenser, it is also possible to automatically release the clamps 3 and 5 and drop the twist line 2 'from each clamp to the finished product storage area. In this case, the wire insertion grooves 3c and 5a of the clamps 3 and 5 are positioned downward.

  The process in the first cycle is completed in steps 1 to 15 in FIG. 5, and the process in the second cycle is continuously performed as indicated by an arrow B in FIG. In FIG. 5, as shown by an arrow C, the process from the wire removal in step 1 to the B end setting of the wire 2 in step 4 is repeatedly performed by the operator on the wire setting surfaces 7 and 10 of the apparatus 1. The 1/3 rotation operation of the intermittent rotating bodies 4 and 13 in Step 5 of the second cycle is automatically performed.

  From the second cycle, the process from the 1/3 rotation of each of the intermittent rotating bodies 4 and 13 in step 5 indicated by arrow D to the rotation surface unlocking in step 11, that is, simultaneously with the processing on the twisted surfaces 8 and 11 The electric wire set in steps 1 to 4 is performed, and at the same time, the steps from 1/3 rotation of the intermittent rotating bodies 4 and 13 in step 12 shown by arrow E to the payout in step 15 are performed. That is, the electric wire setting process in steps 1 to 4, the electric wire pair twisting process in steps 5 to 11, and the tape winding / dispensing process in steps 12 to 15 are repeated simultaneously on the respective processed surfaces 7 to 9 and 10 to 12. Done.

  Thus, a twisted wire that requires multiple stages of processing, such as an operator repeatedly performing only an electric wire set without waiting time, and an equipment (device 1) repeatedly performing twisting processing, tape winding and dispensing without waiting time. By dividing the processing surfaces 7-9, 10-12 into a plurality (three) for 2 ′, the respective operations can proceed simultaneously, and the time required for processing the twisted wire 2 ′ can be shortened. Can do. In addition, the machined surfaces 7-9, 10-12 are arranged on three sides of the triangle and rotated intermittently, thereby reducing the width of the device 1 (the horizontal dimension perpendicular to the longitudinal direction of the wire). Space can be saved, and the mounting area of the apparatus 1 in the factory can be reduced.

  The twisted wire manufacturing apparatus and manufacturing method according to the present invention are used for manufacturing a twisted wire applied to, for example, a signal wire for noise prevention for automobiles with high productivity and in a space-saving manner in an elongated space in a factory. be able to.
