At this time, a portion of the electric wire body 90 between the fixed clamp 20 and the moving clamp 30 is linear. That is, the axis of the part gripped by the fixed clamp 20 in the electric wire body 90 and the axis of the part gripped by the moving clamp 30 are coaxial.

  Next, the moving clamp 30 is moved from the initial position to the target position by the moving clamp actuator (moving step) (FIG. 7). As a result, a portion (hereinafter referred to as “knitting portion 92a”) between the reference location H1 gripped by the fixed clamp 20 and the braiding gripping portion H2 gripped by the moving clamp 30 in the knitting wire 92 is axial. Swelled by being compressed to spread the stitches in the knitted wire portion 92a.

  Next, the stitch enlarging jig 41 in the closed state is moved forward (downward in the figure), and the tip of the collar portion 46 formed by aligning the upper collar portion 42b and the lower collar portion 43b up and down is knitted portion 92a. Stab into a part of the stitch (Fig. 8).

  Next, after opening the stitch enlarging jig 41 up and down, the stitch enlarging jig 41 is further moved forward (stitch enlarging step) (FIG. 9). Thereby, after the stitch in which the tip of the collar portion of the stitch expansion jig 41 is stabbed is expanded, the upper collar portion 42b and the lower collar portion 43b enter the expanded stitch, and the upper collar portion 42b and the lower collar portion 42b The strands of the knitting wire 92 constituting the stitch are moved forward by the collar portion 43b, the front surface 42a1 of the upper base portion 42a, and the front surface 43a1 of the lower base portion 43a, and the electric wires 91 are exposed from the knitting wire 92.

  Next, the stitch enlarging jig 41 is moved backward and returned to the initial position (FIG. 10).

  Next, after moving the horizontal arm portion 52 of the separating portion 50 so as to protrude in the horizontal direction from the arm base portion 51 and intersecting the electric wire 91 exposed from the braided wire 92, the vertical arm portion 53 is moved to its lower end 53a. Is moved to a lower position below the electric wire body 90 and inserted between the electric wire 91 and the braided wire 92 (FIG. 11). Thereby, when it sees from a horizontal direction, the electric wire 91 and the vertical arm part 53 cross | intersect.

  Next, the horizontal arm portion 52 is moved so as to be accommodated (immersed) in the arm base portion 51 (FIG. 12). As a result, the vertical arm portion 53 is hooked on the electric wire 91, and the electric wire 91 is pulled out from the braided wire 92.

  Then, the movement of the horizontal arm 52 into the arm base 51 is further advanced (separation step) (FIG. 12). Thereby, the whole electric wire 91 in the terminal part 95 is pulled out from the braided wire 92, and the electric wire 91 and the braided wire 92 are isolate | separated.

  In this way, the wire 91 and the braided wire 92 in the terminal portion 95 of the wire body 90 are separated.

  As described above, according to the present embodiment, the fixed clamp 20 grips the terminal portion (reference portion H1) of the insulating coating 93 of the electric wire body 90, and the moving clamp 30 is the terminal portion 95 of the electric wire body 90. The knitting wire gripping portion H2 that is spaced from the reference portion H1 of the knitting wire 92 exposed at the end of the wire body 90 is gripped so that only the knitting wire 92 moves together with the movement. The moving clamp actuator moves the moving clamp 30 from the initial position at which the braided gripping portion H2 is first gripped to a target position closer to the reference location H1 than the initial position, and the reference in the exposed braiding 92 A portion between the portion H1 and the braided wire gripping portion H2 is inflated. The stitch enlargement unit 40 enlarges a part of the stitches in the inflated portion of the knitting line 92. Then, the separation unit 50 separates the electric wire 91 and the knitted wire 92 by pulling out the electric wire 91 from the enlarged stitch.

  Thus, the knitted wire 92 is expanded to expand the stitches, and the expanded stitches are further expanded. Therefore, the electric wires 91 can be easily pulled out from the expanded stitches. Therefore, it is possible to more easily separate the electric wire 91 and the knitted wire 92 of the terminal portion 95 from the electric wire body 90 having the knitted wire 92 in which a plurality of strands are knitted into a tubular shape.

  Further, the stitch enlarging jig 41 of the stitch enlarging portion 40 includes a base 45 and an openable / closable collar 46 formed so as to protrude from the base 45, and the collar 46 intersects the axis of the electric wire body 90. The stitch enlargement jig 41 is provided so as to be movable in the one direction. Since it did in this way, by moving the stitch expansion jig 41 in one direction in which the collar portion 46 faces and inserting the stitch in the closed state while the collar portion 46 is closed, the stitch portion 46 is opened. The knitting line 92 is caught and enlarged. Therefore, a part of the stitches of the part can be easily enlarged. Therefore, it is possible to more easily separate the electric wire 91 and the knitted wire 92 of the terminal portion 95 from the electric wire body 90 having the knitted wire 92 in which a plurality of strands are knitted into a tubular shape.

  Further, the collar portion 46 of the stitch enlarging jig 41 is formed so as to protrude from the front surfaces 42 a 1 and 43 a 1 of the base portion 45. Since it did in this way, by moving the stitch expansion jig 41 in one direction in which the collar portion 46 faces and inserting the stitch in the closed state while the collar portion 46 is closed, the stitch portion 46 is opened. The knitting line is caught and enlarged. Then, by further moving the stitch enlarging jig 41 in the one direction, the knitting wire 92 is caught in the vicinity of the flange 46 on the front faces 42a1 and 43a1 of the base 45, and can be moved together with the stitch enlarging jig 41. Therefore, the electric wire 91 can be taken out of the knitted wire 92 from the expanded stitch. Therefore, it is possible to more easily separate the electric wire 91 and the knitted wire 92 of the terminal portion 95 from the electric wire body 90 having the knitted wire 92 in which a plurality of strands are knitted into a tubular shape.

  Further, the braided wire gripping means has a pair of gripping pieces that can be contacted and separated from each other, and a V-shaped groove along the extending direction of the electric wire body is formed on the contacting and separating surfaces facing each other in the pair of gripping pieces. . Since it did in this way, a knitting line can be hold | gripped more uniformly and it can be made easy to move only a knitting line.

  Further, the knitting wire gripping portion that grips the reference portion H1 of the electric wire body 90 and that is spaced closer to the end of the electric wire body 90 with respect to the reference portion H1 in the knitting wire 92 exposed in the terminal portion 95 of the electric wire body 90. H2 is gripped so that only the knitting line 92 moves together with the movement. The braided wire gripping portion H2 is moved from the initial position where the braided wire gripping portion H2 was first gripped to a target position closer to the reference location H1 than the initial position, and is located between the reference location H1 and the braided wire gripping location H2 in the exposed knitting wire 92. The braided portion 92a is inflated. A part of the stitches in the knitted wire portion 92a in which the knitted wire 92 is inflated is enlarged. And the electric wire 91 and the braided wire 92 are isolate | separated by pulling out the electric wire 91 from the expanded stitch.

  Thus, the knitted wire 92 is expanded to expand the stitches, and the expanded stitches are further expanded. Therefore, the electric wires 91 can be easily pulled out from the expanded stitches. Therefore, it is possible to more easily separate the electric wire 91 and the knitted wire 92 of the terminal portion 95 from the electric wire body 90 having the knitted wire 92 in which a plurality of strands are knitted into a tubular shape.

And an actuator portion (not shown) that moves in the oblique direction. The stitch expansion part 40A is attached to the substrate part 10 via an actuator part (not shown).

  Next, an example of operation | movement of the electric wire body processing apparatus of this embodiment is demonstrated with reference to FIGS.

FIGS. 15-21 is a top view explaining operation | movement of the electric wire body processing apparatus 2 of FIG. 15 to 21, for convenience of explanation, only the fixed clamp 20, the moving clamp 30, the stitch enlarging jig 41, the vertical arm portion 53, and the electric wire body 90 are described, and the description of other configurations is omitted. Yes. 15 to 21 schematically show the following states (1) to (7) in order.
(1) Initial state (2) State where the moving clamp is moved to the target position (3) State where the moving clamp is moved to the crossing position (4) State where the heel portion of the stitch enlarging jig is pierced into the stitch of the knitting line (5) ) The state where the electric wire is exposed from the knitted wire (6) The state where the stitch enlargement jig is returned to the initial position, and the vertical arm portion is inserted between the electric wire and the knitted wire. Separated

  The electric wire body processing apparatus 2 holds the terminal portion (reference portion H1) of the insulating coating 93 of the electric wire body 90 with the fixed clamp 20 (reference holding step), and the moving clamp 30 includes the terminal portion of the electric wire body 90. A knitting wire gripping portion H2 of the knitting wire 92 is gripped by sandwiching 95 (knitting wire gripping step) (FIG. 15). At this time, a portion of the electric wire body 90 between the fixed clamp 20 and the moving clamp 30 is linear. That is, the axis of the part gripped by the fixed clamp 20 in the electric wire body 90 and the axis of the part gripped by the moving clamp 30 are coaxial.

  Next, the moving clamp 30 is moved from the initial position to the target position by the moving clamp actuator (moving step) (FIG. 16). As a result, a portion (hereinafter referred to as “knitting portion 92a”) between the reference location H1 gripped by the fixed clamp 20 and the braiding gripping portion H2 gripped by the moving clamp 30 in the knitting wire 92 is axial. Swelled by being compressed to spread the stitches in the knitted wire portion 92a.

  Next, the sub-board part 11 is swung by a swinging actuator (swinging step) (FIG. 17). Thereby, the movement clamp 30 is moved from the target position to the crossing position with the swing of the sub-board part 11, and the axis line at the reference point H1 of the electric wire body 90 and the axis line at the braided wire holding point H2 of the electric wire body 90 are formed. Intersect. That is, a portion of the electric wire body 90 between the fixed clamp 20 and the moving clamp 30 is bent in a curved shape convex to the right rear, and the stitches of the outer portion of the curved line 92 are further expanded.

  Next, the stitch enlarging jig 41 in the closed state is moved obliquely from the right rear to the left front, and the tip of the collar 46 formed by aligning the upper collar 42b and the lower collar 43b up and down is knitted. A part of the stitches of the portion 92a is pierced (FIG. 18).

  Next, after opening the stitch enlarging jig 41 up and down, the stitch enlarging jig 41 is further moved obliquely in the left front direction (stitch enlarging step) (FIG. 19). Thereby, after the stitch in which the tip of the collar portion of the stitch expansion jig 41 is stabbed is expanded, the upper collar portion 42b and the lower collar portion 43b enter the expanded stitch, and the upper collar portion 42b and the lower collar portion 42b The strands of the knitting wire 92 constituting the stitch are moved diagonally in the left front direction by the collar portion 43b, the front surface 42a1 of the upper base portion 42a, and the front surface 43a1 of the lower base portion 43a, and the electric wire 91 is exposed from the knitting wire 92. To do.

  Next, the stitch enlarging jig 41 is moved diagonally rearward to the right and returned to the initial position. And after moving the horizontal arm part 52 of the isolation | separation part 50 so that it may protrude in the horizontal direction from the arm base 51, and making it cross | intersect with the electric wire 91 exposed from the braid 92, the lower end 53a of the vertical arm part 53 is used. It is moved to a lower position below the electric wire body 90 and inserted between the electric wire 91 and the braided wire 92 (FIG. 20). Thereby, when it sees from a horizontal direction, the electric wire 91 and the vertical arm part 53 cross | intersect.

  Next, the horizontal arm portion 52 is moved so as to be accommodated (immersed) in the arm base portion 51. As a result, the vertical arm portion 53 is hooked on the electric wire 91, and the electric wire 91 is pulled out from the braided wire 92. Then, the movement of the horizontal arm 52 into the arm base 51 is further advanced (separation step) (FIG. 21). Thereby, the whole electric wire 91 in the terminal part 95 is pulled out from the braided wire 92, and the electric wire 91 and the braided wire 92 are isolate | separated.

  In this way, the wire 91 and the braided wire 92 in the terminal portion 95 of the wire body 90 are separated.

  According to this embodiment, in addition to the effect of 1st Embodiment mentioned above, there exist the following effects.

  When the moving clamp 30 is at the initial position and the target position by the swinging of the sub board portion 11 by the swinging actuator, the axis line at the reference position H1 of the electric wire body 90 and the braided wire gripping position H2 of the electric wire body 90 are obtained. After the moving clamp 30 is moved from the initial position to the target position, the axis line at the reference point H1 of the electric wire body 90 and the axis line at the knitting wire holding point H2 of the electric wire body 90 intersect each other. The moving clamp 30 is moved to the intersection position. Since it did in this way, since the part between the reference | standard location H1 and the knitting wire holding location H2 in the knitting wire 92 is bent, the electric wire 91 is pulled from the knitting wire 92 toward the outer side of the bending, thereby Can be easily pulled out. Further, the stitches on the outside of the bend in the knitting line 92 are further expanded. Therefore, a part of the stitches of the part is easily enlarged. Therefore, it is possible to more easily separate the electric wire 91 and the knitted wire 92 of the terminal portion 95 from the electric wire body 90 having the knitted wire 92 in which a plurality of strands are knitted into a tubular shape.

  Although the present invention has been described with reference to the preferred embodiments, the wire body processing apparatus and the wire body processing method of the present invention are not limited to the configurations of these embodiments.

  For example, in each of the above-described embodiments, the moving clamp 30 is directly moved from the initial position to the target position, but the present invention is not limited to this. For example, as shown in FIG. 22, the moving clamp 30 is located between the reference position H1 and the knitting line gripping position H2 in the knitting line 92 between the fixed clamp 20 and the fixed clamp 20 from the initial position (knitting). It may be configured to move to a position sandwiching the line portion 92a) and then move back to the target position shown in FIG.

  By doing in this way, the knitting line portion 92a between the reference point H1 and the knitting line gripping portion H2 in the knitting line 92 is sandwiched between the fixed clamp 20 and the moving clamp 30 and is once crushed in the axial direction. Since the knitted wire portion 92a is expanded in the axial direction, the shape of the knitted wire portion 92a is stabilized. Therefore, a part of the stitches of the knitted wire portion 92a can be easily expanded. Therefore, it is possible to more easily separate the electric wire 91 and the knitted wire 92 of the terminal portion 95 from the electric wire body 90 having the knitted wire 92 in which a plurality of strands are knitted into a tubular shape.

  In each of the embodiments described above, in the stitch enlarging jig 41, the lower surface of the upper base portion 42a and the lower surface of the upper collar portion 42b are flush with each other, and the upper surface of the lower base portion 43a and the upper surface of the lower collar portion 43b are In the closed state, the lower surface of the upper base portion 42a and the lower surface of the upper collar portion 42b in the upper piece portion 42, and the upper surface of the lower base portion 43a and the upper surface of the lower collar portion 43b in the lower piece portion 43 are Abut. Therefore, as shown in FIG. 23, in the closed state, the strand 92s constituting the knitted wire 92 may enter between the lower surface of the upper collar portion 42b and the upper surface of the lower collar portion 43b for some reason. There is a possibility that the stitches cannot be expanded sufficiently.

  Therefore, instead of the stitch expansion jig 41 described above, as shown in FIG. 24, a sharp head 43d swelled in the thickness direction (vertical direction) is provided at the tip of the triangular plate-like lower collar portion 43c of the collar portion 46A. In the closed state, a stitch enlarging jig 41A having a shape in which the tip of the upper collar portion 42c is hidden by the head 43d when viewed from the front may be used. 24A, 24B, and 24C are a plan view, a side view, and a front view, respectively, of the stitch enlarging jig 41A. Then, as shown in the enlarged side view of FIG. 24 (d), in the stitch enlarging jig 41A, when viewed from the front (that is, the direction of piercing the knitting wire 92), the head 43d of the lower collar portion 43c Since the tip of the upper collar portion 42c is hidden, the gap between the upper collar portion 42c and the lower collar portion 43c cannot be seen from the front, and therefore, the strand 92s of the knitted wire 92 is prevented from entering the gap. can do.

  Alternatively, as shown in FIG. 25, instead of the above-described stitch enlarging jig 41, the collar portion 46B has a left collar portion 42e and a right collar portion 43e that are divided in the left-right direction, and these are the upper base portions, respectively. A stitch enlarging jig 41B provided so as to protrude from the front surface 42a1 of 42a and the front surface 43a1 of the lower base portion 43a may be used. 25A, 25B, and 25C are a plan view, a side view, and a front view, respectively, of the stitch enlarging jig 41B. In this configuration, the gap between the left brim portion 42e and the right brim portion 43e is in a direction (vertical direction) intersecting the extending direction of the strands of the knitting wire 92. The entry of the line 92s can be suppressed.

  Moreover, in each embodiment mentioned above, when the length of the terminal part 95 of the electric wire body 90 becomes comparatively long, the frictional force between the electric wire 91 and the braided wire 92 becomes large, and only the moving clamp 30 is knitted. It may be impossible to move only the line 92. Therefore, for example, as shown in FIG. 26, the auxiliary movement knitting wire gripping portion H3 spaced apart from the end of the electric wire body 90 with respect to the knitting wire gripping portion H2 in the knitting wire 92 is knitted with movement. Before moving the moving clamp 30 by the moving clamp actuator 35, the auxiliary moving clamp 35 gripping so that only 92 moves together, the auxiliary moving clamp 35 closest to the end of the wire body 90 is moved to the auxiliary movement. Auxiliary movement target closer to the reference position H1 than the initial position for auxiliary movement from the initial position for auxiliary movement (position shown in FIG. 24A) at which the auxiliary movement knitting wire holding position H3 is first grasped. It is good also as a structure further provided with the actuator for auxiliary movement which is not shown in figure which moves to a position (position shown in Drawing 24 (b)). The auxiliary movement clamp 35 has the same configuration as the movement clamp 30. The auxiliary movement actuator corresponds to auxiliary movement means. After the auxiliary movement clamp 35 is moved to the auxiliary movement target position, the movement clamp 30 is moved from the initial position to the target position by the movement clamp actuator. At this time, the auxiliary movement clamp 35 may be moved closer to the reference location H1 from the auxiliary movement target position.

  Alternatively, as shown in FIG. 27, a plurality of auxiliary movement clamps 35 and 36 may be provided. In this configuration, before the moving clamp 30 is moved by the moving clamp actuator, the auxiliary moving clamp 35 is arranged in the order of the auxiliary moving clamps 35 and 36 closest to the end of the electric wire 90. , 36 are moved from the auxiliary movement initial position at which the auxiliary movement knitting wire holding positions H3 and H4 are first held to the auxiliary movement target position closer to the reference position H1 than the auxiliary movement initial position.

  Since the end portion 95 where the braided wire 92 in the electric wire body 90 is exposed is relatively long and the frictional force between the electric wire 91 and the braided wire 92 is large, the moving clamp 30 alone is When it is difficult to move the knitting wire gripping portion H2 in the knitting wire 92 closer to the reference location H1, the knitting wire 92 is moved from the end of the electric wire body 90 toward the reference location H1 by the auxiliary movement clamp and the auxiliary movement actuator. Can be moved gradually. There may be one auxiliary movement clamp or a plurality of auxiliary movement clamps.

  27, after the auxiliary movement clamp 35 closest to the end of the electric wire body 90 is moved by the auxiliary movement actuator, the electric wire clamp 38 that holds the terminal portion of the electric wire 91 of the electric wire body 90. May be further provided. By doing in this way, the buckling of the electric wire body 90 accompanying the movement of the movement clamp 30 and the auxiliary movement clamps 35 and 36 can be suppressed.

  In each of the above-described embodiments, after the stitches of the knitting wire 92 are enlarged by the stitch enlargement jig 41, the stitch enlargement jig 41 is moved away from the knitting wire 92, and then the vertical arm portion 53 is connected to the electric wire 91 and the knitting wire 92. However, the present invention is not limited to this.

  For example, in the first embodiment described above, the vertical arm portion 53 (bar-shaped member) can be attached to and detached from the tip of the horizontal arm portion 52 of the separation portion 50, and the horizontal arm is attached to the collar portion 46 of the stitch enlarging jig 41. It is good also as 1 A of electric wire body processing apparatuses which have the structure which provided the fitting hole 47 which the vertical arm part 53 removed from the front-end | tip of the part 52 fits. The fitting hole 47 may be provided in the base portion 45 of the stitch enlarging jig 41. The operation of the wire body processing apparatus 1A having such a configuration will be described below with reference to FIGS.

  28-30 is a figure explaining the operation | movement in the structure of the 3rd modification of the electric wire body processing apparatus of FIG. 1, Comprising: Each before inserting a vertical arm part between an electric wire and a braided wire The state after inserting a vertical arm part between an electric wire and a braided wire, and the state which pulled and separated the electric wire from the braided wire are shown. In each figure, (a) is a plan view and (b) is a front view.

  In the electric wire body processing apparatus 1A, the operation until the electric wire is exposed from the braided wire is the “(1) initial state” (FIG. 6) to “(4) the electric wire is exposed from the braided wire in the first embodiment. ”(FIG. 9).

  Next, after moving the horizontal arm portion 52 of the separating portion 50 so as to protrude in the horizontal direction from the arm base portion 51 and intersecting the electric wire 91 exposed from the braided wire 92 (FIG. 28, in this figure, the horizontal arm portion). 52 is omitted), the vertical arm portion 53 is moved to a lower position where the lower end 53a is below the electric wire body 90, and is inserted into and fitted into the fitting hole 47 of the flange portion 46 (see FIG. 29). Thereby, the vertical arm portion 53 is inserted between the electric wire 91 and the braided wire 92. In this state, the electric wire 91 and the vertical arm portion 53 intersect when viewed from the horizontal direction.

  Next, the stitch enlarging jig 41 is moved backward and returned to the initial position (FIG. 30). Thereby, the whole electric wire 91 in the terminal part 95 is pulled out from the braided wire 92, and the electric wire 91 and the braided wire 92 are isolate | separated. In this manner, the electric wire 91 and the braided wire 92 in the terminal portion 95 of the electric wire body 90 may be separated.

  That is, in this configuration, the stitch enlarging jig 41 is moved forward with the heel portion 46 closed, whereby the heel portion 46 is pierced into the stitch of the knitting line 92 and the heel portion 46 is pierced into the stitch. When the collar portion 46 is opened, the stitches are enlarged, and the wire 91 of the terminal portion 95 is exposed to the outside of the knitting wire 92 from the stitches enlarged by further moving in one direction with the collar portion 46 opened. Thus, the electric wire 91 and the braided wire 92 of the terminal portion 95 are separated in the front-rear direction. Then, the vertical arm portion 53 is inserted between the electric wire 91 and the braided wire 92 of the terminal portion 95 in a state where the stitch expanding jig 41 separates the electric wire 91 and the braided wire 92 of the terminal portion 95 in the front-rear direction. .

  In this way, when the stitch enlarging jig 41 separates the stitch expanding jig 41 from the knitting wire 92 after the electric wire 91 and the knitting wire 92 of the terminal portion 95 are separated in the front-rear direction, the shape of the knitting wire 92 is obtained. Is restored and the gap (gap) between the electric wire 91 and the braided wire 92 of the terminal portion 95 becomes small, and it becomes difficult to insert the vertical arm portion 53 between them. By inserting the vertical arm portion 53 between the electric wire 91 and the braided wire 92 of the terminal portion 95 in a state in which the electric wire 91 and the braided wire 92 are separated in the front-rear direction, the vertical arm portion 53 is reliably inserted between the wires 91 and the braided wire 92. Can be inserted, and the electric wire 91 and the braided wire 92 of the terminal portion 95 can be more reliably separated.

  Further, in each of the above-described embodiments, after the stitch is enlarged by the stitch enlargement jig 41, the stitch enlargement jig 41 is moved in the direction in which the tip of the collar portion 46 faces to expose the electric wire 91 from the knitting wire 92. However, it is not limited to this. For example, after enlarging the stitch, the stitch enlarging jig 41 is returned to the initial position, and a drawer jig provided with a chuck at the tip is inserted into the enlarged stitch, and the electric wire 91 is connected from the knitting wire 92. It is good also as a structure pulled out.

  The above-described embodiments are merely representative forms of the present invention, and the present invention is not limited to the embodiments. That is, those skilled in the art can implement various modifications in accordance with conventionally known knowledge without departing from the scope of the present invention. Of course, such modifications are also included in the scope of the present invention as long as they have the configuration of the wire body processing apparatus and the wire body processing method of the present invention.
