Description

  [Technical Field] The present invention relates to a coated twisted wire scoring device for straightening and straightening a coated twisted wire.

  In a terminal crimping apparatus that crimps a terminal to an end of an electric wire such as a coated stranded wire or a coated single wire, the supplied electric wire is wound around a reel. When the electric wire wound on the reel is pulled out, the electric wire is bent and bent. If it supplies to a terminal crimping apparatus in this state, the edge part of an electric wire will slip | deviate from the position which crimps | bonds a terminal, and it becomes impossible to crimp a terminal. For this reason, the wire is removed from the wire by the wire take-up device and straightened and then supplied to the terminal crimping device.

  As this scraping device, Patent Document 1 discloses a first roller group in which a plurality of rollers are alternately arranged in two rows in the vertical direction in the electric wire conveyance direction, and the first roller group is separated from the first roller group in the electric wire conveyance direction. And a second roller group in which a plurality of rollers are horizontally arranged in two rows alternately in the electric wire conveyance direction. The technique of this patent document 1 intends to remove the wrinkle of the electric wire by meandering the electric wire sent by the electric wire conveying device up and down by the first roller group and horizontally meandering by the second roller group. doing.

  However, in the technique of Patent Document 1, since the first roller group and the second roller group require a large number of rollers, the scraping device is naturally large, and it is difficult to reduce the size, and the number of parts is small. There was a problem that the cost would be high because there are many.

JP 2013-93272 A

  Therefore, in view of the above circumstances, it is an object of the present invention to provide a coated twisted wire scraping device that can be reduced in size and reduced in cost.

  In order to solve the above-described problem, the coated twisted wire scoring device according to the present invention includes: “a square bar-shaped base portion and a covered twisted wire sandwiched from a direction perpendicular to the longitudinal direction of the base portion; A pair of first rollers rotatably mounted on one end side in the longitudinal direction of the base, a direction perpendicular to the pair of first rollers, and in the longitudinal direction of the base portion A covered stranded wire is sandwiched from a direction orthogonal to the base portion, and is rotatably attached to an end portion side opposite to the end portion side to which the pair of first rollers are attached in the longitudinal direction of the base portion. A pair of second rollers, a first adjustment mechanism that is attached to the base portion and adjusts a distance between the pair of first rollers, and a space between the pair of second rollers that is attached to the base portion A second adjusting mechanism for adjusting There "that characterized.

  Here, the “coated stranded wire” is obtained by coating a core wire obtained by twisting a plurality of single metal wires with an insulating material such as synthetic resin or rubber. Moreover, a 1st roller and a 2nd roller are free rollers which rotate with conveyance of a covered twisted wire.

  As described above, the wire twisting device of the present configuration is configured to convey the wire in a state where the coated stranded wire drawn from the reel is sandwiched between the pair of first rollers and the pair of second rollers. Pulling and transporting the coated stranded wire with the device, and removing the crease in one direction with the pair of first rollers, and taking out the crease in the direction perpendicular to the direction with the pair of second rollers, Can be corrected straight. As will be described in detail later, the wire twisting device for coated stranded wire of this configuration is not very effective for wire covering single coated wire, but can effectively wire the coated stranded wire. Therefore, when the wire twisting device for coated stranded wire of this configuration is used for a terminal crimping device, a straightened coated stranded wire can be supplied to the terminal crimping device, so that a terminal is attached to the end of the coated stranded wire. It can be surely crimped.

  Moreover, according to the covering twisted wire scraping device of this configuration, the first adjustment mechanism for adjusting the distance between the pair of first rollers and the second adjustment mechanism for adjusting the distance between the pair of second rollers are provided. Therefore, the distance between the pair of first rollers and the pair of second rollers is adjusted by the first adjustment mechanism and the second adjustment mechanism so that the optimum distance (clamping force) can be obtained to remove the wrinkles of the coated stranded wire. can do. Also, by adjusting the distance between the pair of first rollers and the distance between the pair of second rollers by the first adjustment mechanism and the second adjustment mechanism, the coated stranded wires of various thicknesses (diameters) are sandwiched between It can be taken and versatility can be improved.

  Moreover, according to the covering twisted wire scoring device of this configuration, the covering twisted wire can be picked up by four rollers of a pair of first rollers and a pair of second rollers. Thus, it is not necessary to use a large number of rollers, and the size can be reduced, the number of parts can be reduced, and the cost can be reduced.

  By the way, in the technique of patent document 1, since the several roller of the 1st roller group and the 2nd roller group is rotating by the contact of the electric wire pulled and conveyed by the electric wire conveyance apparatus, an electric wire conveyance apparatus is used for the electric wire. When the conveyance is stopped, the plurality of rollers do not stop due to the inertial force, and the contacting electric wire is sent and the electric wire is bent between the electric wire conveying device and the scraping device. There was a problem that the electric wire that took the sword was bent. And if an electric wire bends between an electric wire conveyance apparatus and a scraping apparatus, when conveyance of an electric wire was restarted, there existed a possibility that a terminal could not be crimped | bonded by the bent part. Therefore, in the technique of Patent Document 1, the wire feed rate is suppressed so that the inertial force of the roller does not increase, and the wire feed rate cannot be increased.

  On the other hand, since the winding device for the coated stranded wire of this configuration includes only four rollers, that is, a pair of first rollers and a pair of second rollers, the technique of Patent Document 1 including many rollers. In comparison with the roller, the inertial force of the roller is small. Further, unlike the technique of Patent Document 1, since the coated stranded wire is “sandwiched” by the pair of rollers, the frictional resistance between the first roller or the second roller and the coated stranded wire is high. For this reason, when the conveyance of the coated stranded wire is stopped, the rotation of the first roller and the second roller is also stopped at the same time, and the coated stranded wire is not sent excessively. Therefore, when the transport of the coated stranded wire is stopped, the coated stranded wire once stripped is bent and bent on the transport side (for example, between the wire transport device and the scooping device) rather than the scooping device. Therefore, when the conveyance is resumed, the bent coated stranded wire is not supplied in the subsequent process (for example, the crimping of the terminal to the end by the terminal crimping device). It is possible to prevent the occurrence of problems due to bending (butterfly).

  Further, as described above, since the rotation of the pair of first rollers and the pair of second rollers is stopped simultaneously with the stop of the transport of the covered twisted wire, the transport of the covered twisted wire is compared with the technique of Patent Document 1. The speed can be increased. Accordingly, when the wire twisting device of the present configuration is used in a terminal crimping device, the supply speed of the coated twisted wire to the terminal crimping device can be increased. Manufacturing efficiency of the electric wire) can be improved.

  In addition to the above-described configuration, the coated twisted wire scraping device according to the present invention includes: “the pair of first rollers and the pair of second rollers have at least an outer peripheral surface in contact with the coated twisted wire made of a hard material. It may be characterized by being “formed”.

  As a result of the inventor's experiment, when a soft material such as rubber or foamed resin is used as the material of the outer peripheral surface that contacts the coated stranded wire in the pair of first rollers or the pair of second rollers, It was found that the clamping force tends to be insufficient and it is difficult to sufficiently remove the wrinkles. Therefore, a hard material such as “metal”, “hard resin”, “stone”, “hardwood”, etc. is used as the material of the outer peripheral surface that contacts at least the coated stranded wire in the pair of first rollers and the pair of second rollers. By using it, the wrinkles of the coated stranded wire can be effectively removed.

  As described above, as an effect of the present invention, it is possible to provide a coated twisted wire scoring device that can be reduced in size and reduced in cost.

In the first adjustment mechanism 13, the adjustment base 21 has one of four side surfaces parallel to the longitudinal direction facing the front surface of the base portion 10, and the second adjustment mechanism 14 is parallel to the longitudinal direction. One of the four side surfaces faces the upper surface of the base portion 10. The roller 5 (the first roller 11 or the second roller 12) is rotatably attached to the adjustment base 21 on the outer end side in the longitudinal direction of the base portion 10.

  The guide shaft 22 is attached to the adjustment base 21 in a state of protruding outward from the surface of the adjustment base 21 facing the base portion 10 side, and the distal end side is slidably inserted into the base portion 10. ing. Two guide shafts 22 are provided in parallel, spaced apart in the longitudinal direction of the adjustment base 21.

Further, the counter body 25 has a lock lever 25b that prevents the adjustment bolt 24 (adjustment knob 26) from rotating when operated.

  Although the detailed illustration of the lock member 27 is omitted, the adjustment bolt 24 is inserted and has a long hole in the sliding direction. When the lock member 27 is moved to the lock position side and the end of the long hole is inserted into the lock groove of the adjustment bolt 24, the movement of the adjustment bolt 24 in the axial direction with respect to the adjustment base 21 is restricted (locked). can do. The lock member 27 is configured so that the adjustment bolt 24 can be rotated even in a locked position where the movement of the adjustment bolt 24 in the axial direction is restricted.

  The rotation restricting member 30 is formed in a U shape so as to cover the counter body 25 from the side of the counter body 25 from which the adjustment bolt 24 extends. The rotation regulating member 30 is configured such that when the adjustment knob 26 is rotated, the counter main body 25 comes into contact with two flat plate-like portions extending in parallel, whereby the counter main body 25 is connected to the adjustment knob 26 (adjustment bolt 24). It is possible to prevent the rotation of the counter body 25, and to restrict the rotation of the counter body 25 around the axis of the adjustment bolt 24.

  The guide mechanism 15 includes a bracket 41 attached to the base portion 10 and a guide bush 42 attached to the bracket 41 and through which the covered stranded wire 2 is inserted. The bracket 41 is a pair of flat plate-like support plates extending in the same direction at right angles from each of the two flat sides of the rectangular plate-like substrate portion 41a whose outer shape is longer than the diameter of the roller 5 and the substrate portion 41a. Part 41b. The substrate portion 41 a is attached between the base portion 10 and the roller 5 with the long side parallel to the longitudinal direction of the base portion 10. The pair of support plate portions 41 b protrude from the substrate portion 41 a to the other roller 5 side beyond one roller 5 attached to the base portion 10. Guide bushes 42 are coaxially attached to portions of the pair of support plate portions 41b protruding from the substrate portion 41a. The bracket 41 is formed by bending a metal plate.

  Each of the pair of guide bushes 42 has a cylindrical part and a flange-like part protruding outward from one end of the cylindrical part in a disk shape. The guide bush 42 is attached to the bracket 41 with the cylindrical portion passing through the support plate portion 41b of the bracket 41 with the flange-shaped portion facing outward. The pair of guide bushes 42 are located on both sides of the base portion 10 in the longitudinal direction of the roller 5 between the pair of rollers 5. The guide bush 42 is made of synthetic resin.

  Then, the usage method of the harvesting apparatus 1 is demonstrated. First, in the first adjustment mechanism 13 and the second adjustment mechanism 14, the lock by the lock member 27 is released so that the adjustment base 21 can move in the axial direction of the adjustment bolt 24, and the adjustment base 21 is attached to the isolation spring 23. It is moved in a direction away from the base portion 10 by force (see FIG. 3). In this state, the counter body 25 and the part of the rotation restricting member 30 attached to the slide mounting member 29 are in contact with each other, and the distance between the pair of rollers 5 (the first roller 11 and the second roller 12) is greatly separated. ing.

  The first roller 11 and the second roller 11 pass between the pair of first rollers 11 and between the pair of second rollers 12 so that the covered twisted wire 2 passes between the pair of first rollers 11 and the lock member 27 unlocked. The covered stranded wire 2 is inserted through a pair of guide bushes 42 of the guide mechanism 15 provided in the vicinity of each of the rollers 12. At this time, since the pair of first rollers 11 and the pair of second rollers 12 are separated from each other, the coated stranded wire 2 can be easily passed.

  Next, in the first adjustment mechanism 13 and the second adjustment mechanism 14, the respective adjustment bases 21 are moved toward the base portion 10 against the urging force of the isolation spring 23. When the lock member 27 that moves together with the adjustment base 21 reaches the lock groove of the adjustment bolt 24, the lock member 27 moves to the lock position by the urging force of the lock spring 28, and the adjustment bolt 24 moves in the axial direction relative to the adjustment base 21. Is locked, and the movement of the adjustment base 21 is stopped.

  In the state of being locked by the lock member 27, the pair of first rollers 11 and the pair of second rollers 12 approach each other and sandwich the coated stranded wire 2, and in the counter body 25 and the rotation regulating member 30. A gap is formed between the portion attached to the slide attachment member 29.

  When the adjustment knob 26 is rotated in this state, the adjustment bolt 24 whose tip side is screwed to the base portion 10 rotates, and the adjustment bolt 24 advances and retreats with respect to the base portion 10. Since a part of the lock member 27 is inserted into the lock groove of the adjustment bolt 24, the lock member 27 moves forward and backward with respect to the base portion 10 together with the adjustment bolt 24. Since the lock member 27 is attached to the adjustment base 21, the adjustment base 21 moves forward and backward with respect to the base portion 10 together with the adjustment bolt 24 and the lock member 27. The distance between the rollers (between a pair of rollers 5) changes.

  Then, the adjustment knob 26 is rotated in an appropriate direction to adjust the distance between the pair of first rollers 11 and the distance between the pair of second rollers 12 via the adjustment bolt 24 and the adjustment base 21, and thereby the coated twist. An optimum clamping force is applied to the wire 2.

  In this state, for example, when the coated stranded wire 2 is conveyed to the terminal crimping device side by an electric wire conveying device of a terminal crimping device (not shown), the pair of first rollers 11 removes wrinkles in the front-rear direction. The upper and lower wrinkles are removed by the pair of second rollers 12, and the coated stranded wire 2 is straightened.

  Here, when the covered stranded wire 2 and the coated single wire were cut using the winding device 1 of the present embodiment, the covered stranded wire 2 was wrinkled, whereas the covered single wire was wrinkled. There wasn't. The mechanism for removing the wrinkles of the coated stranded wire can be considered as follows.

  First, when the coated single wire is compared with the coated stranded wire 2, the coated single wire has a uniform cylindrical surface because the core wire is a single metal single wire. On the other hand, as shown in FIG. 4 and FIG. 5, the coated stranded wire 2 is formed by twisting a plurality of single wires 3 a of the metal, so that the core wire 3 has a uniform surface. And has spiral irregularities. Further, since the coated stranded wire 2 has irregularities on the surface of the core wire 3, there is a gap between the coated stranded wire 2 and the coating material 4 in the concave portion.

  And in the scraping apparatus 1 of this embodiment, when the coated twisted wire 2 having irregularities on the surface of the core wire 3 is conveyed, it is sandwiched between the pair of rollers 5 (the first roller 11 or the second roller 12). The part to be transferred changes from a convex part on the surface of the core wire 3 to a concave part, and from a concave part to a convex part. When the pair of rollers 5 are convex portions on the surface of the core wire 3, as shown in FIG. 4, some of the single wires 3 a forming the core wire 3 are arranged in a direction sandwiched between the pair of rollers 5. A force is applied so that the single wires 3a approach each other.

  On the other hand, when the pair of rollers 5 is a concave portion on the surface of the core wire 3, the gap between the core wire 3 and the covering material 4 is crushed by the clamping force of the pair of rollers 5, as shown in FIG. Since a force that separates the single wires 3a forming the core wire 3 in the feeding direction and the diametrical direction acts, it is considered that the stranded wire 2 can be removed by this force.

  As described above, according to the winding device 1 of the present embodiment, the coated stranded wire 2 can be straightened and straightened, so that when used in a terminal crimping device, the straightened coated stranded wire is straightened. 2 can be supplied to the terminal crimping device, and the terminal can be securely crimped to the end of the coated stranded wire 2.

  Further, according to the scraping device 1 of the present embodiment, the first adjustment mechanism 13 that adjusts the distance between the pair of first rollers 11 and the second adjustment mechanism 14 that adjusts the distance between the pair of second rollers 12. Therefore, the pair of first rollers 11 and the pair of second rollers are adjusted so that the first adjustment mechanism 13 and the second adjustment mechanism 14 have an optimum interval (clamping force) that can remove the wrinkles of the coated stranded wire 2. Each of the twelve intervals can be adjusted. Further, by adjusting the distance between the pair of first rollers 11 and the distance between the pair of second rollers 12 by the first adjustment mechanism 13 and the second adjustment mechanism 14, the coated stranded wires 2 having various thicknesses (diameters) can be formed. The scissors can be picked and the scissors can be removed, and the versatility of the scissor device 1 can be enhanced.

  Moreover, according to the scissoring device 1 of the present embodiment, since the scissors of the coated stranded wire 2 can be removed with the four rollers of the pair of first rollers 11 and the pair of second rollers 12, Thus, it is not necessary to use a large number of rollers, the size can be reduced, the number of parts can be reduced, and the cost can be reduced.

  Furthermore, according to the scraping device 1 of the present embodiment, since only four rollers 5 of a pair of first rollers 11 and a pair of second rollers 12 are provided, it is compared with the conventional technology provided with many rollers. Thus, the inertial force of the roller 5 is small. Further, unlike the conventional technique, the coated stranded wire 2 is “sandwiched” by the pair of rollers 5, so that the frictional resistance between the roller 5 and the coated stranded wire 2 is high. For this reason, when the conveyance of the coated stranded wire 2 is stopped, the rotation of the first roller 11 and the second roller 12 is also stopped at the same time, and the coated stranded wire 2 is not sent excessively. Therefore, when the conveyance of the coated stranded wire 2 is stopped, the coated stranded wire 2 that has once been crushed on the conveyance side (for example, between the wire conveying device and the rigging device 1) rather than the rigging device 1. Will not bend and bend, so when the transport is resumed, the bent coated stranded wire 2 is not supplied in the subsequent process (crimping the terminal to the end by the terminal crimping device). Generation | occurrence | production of the malfunction resulting from the bending | flexion (blemish) of the twisted wire 2 can be prevented.

  Moreover, according to the winding device 1 of the present embodiment, as described above, the rotation of the pair of first rollers 11 and the pair of second rollers 12 is stopped simultaneously with the stop of the conveyance of the covered twisted wire 2. Compared with the conventional technique, the conveyance speed of the covered stranded wire 2 can be increased. Therefore, when the scraping device 1 of the present embodiment is used for a terminal crimping device, the supply speed of the coated twisted wire 2 to the terminal crimping device can be increased. Manufacturing efficiency of the electric wire) can be improved.

  Although the present invention has been described with reference to the preferred embodiments, the present invention is not limited to the above-described embodiments, and various improvements and design changes can be made without departing from the scope of the present invention. It is.

  For example, in the above embodiment, the coated stranded wire 2 is extended from the front-rear direction by the pair of first rollers 11 and from the vertical direction by the pair of second rollers 12 with respect to the coated stranded wire 2 extending in the left-right direction. However, the present invention is not limited to this. The pair of first rollers 11 may sandwich the coated stranded wire 2 from the up-down direction and the pair of second rollers 12 from the front-rear direction. good.

  In the above embodiment, the first roller 11 and the second roller 12 are all made of metal. However, the present invention is not limited to this, and at least the outer peripheral surface that contacts the coated stranded wire 2. These materials may be a first roller and a second roller made of a hard material such as hard resin, stone, or hardwood.
