Description

  The present invention relates to a method and an apparatus for applying a water-stopping agent to electric wires used when manufacturing a wire harness incorporated in a vehicle.

  In the production of the wire harness, it is necessary to water-stop the part into which the grommet to be installed in the through hole of the vehicle body panel is inserted. The water stop is performed by closing the space between the wires and between the wire and the grommet with a water stop agent or the like. Specifically, after applying a water-stopping agent (silicone, urethane, etc.) to the circumferential surface of the wires arranged in a row so as to overlap in the vertical direction, the wires are gathered, covered with a film from the rounded up, and bundled, Wrap the adhesive tape on it, and attach the grommet at the end.

  As described above, the electric wires that are arranged so as to overlap in the vertical direction and coated with a water-stopper are bundled after that, so that the water between the electric wires and the like can be securely stopped evenly on the peripheral surface of the electric wires. A liquid preparation needs to be applied.

  Various devices have been devised in order to reliably apply the water-stopper. One of them is a technique described in Patent Document 1 below. In this technology, in order to arrange the electric wires in two vertical rows on the wiring board, the electric wire group dispersion receiving jigs are arranged apart from each other, and the water stop is applied to a part of the electric wires located between the electric wire group dispersion receiving jigs. The agent discharger descends and applies a water-stopping agent. This water-stopper dispenser is formed in a rectangular parallelepiped shape with two vertically long grooves so as to cover a plurality of electric wires arranged in two vertical rows, and discharges the water-stopper around and between the wires Therefore, it has a structure having a plurality of nozzles on four surfaces sandwiching the electric wire. That is, application is performed by discharging a water-stopping agent from a plurality of nozzles at once.

  However, in the case where application is performed by discharging a water-stopping agent from a plurality of nozzles arranged in advance around the electric wire in this way, a difference occurs in the amount of water-stopper adhesion between the front surface of the nozzle and other parts, As a result, there is a problem that uneven coating occurs.

  Moreover, the technique of patent document 1 arrange | positions an electric wire in two rows using two electric wire group dispersion | distribution receiving jigs, and the water-stopping agent discharge device formed in the shape which covers an electric wire as mentioned above with respect to this part The structure which applies a water-stopping agent using is adopted. For this reason, when there is a change in the number of wires of the wire harness to be manufactured, in order to cope with the change, the wire group dispersion receiving jig and the water stop agent dispenser itself must be changed each time. There is also a problem.

  Furthermore, since the electric wire group dispersion receiving jig plays a role of dividing a plurality of electric wires into two vertical rows, after applying the water stop agent, the electric wire group dispersion receiving jig is performed for the work to be performed thereafter. The tool must be removed from the wire. However, since the electric wire group dispersion receiving jig is shaped like a fork, in order to remove it from the electric wire, the electric wire group dispersion receiving jig is supported on the wiring board so as to be movable up and down, and a water stop agent It is necessary to control so that the electric wire group dispersion receiving jig is lowered after coating.

Japanese Patent Laid-Open No. 2003-45251

  Accordingly, the main object of the present invention is to ensure that the water-stopping agent can be applied without any unevenness and that it is possible to easily obtain an advantage that even when the number of wires is changed.

For this purpose, a parallel processing for arranging a plurality of electric wires so as to overlap in the vertical direction, and a coating treatment for applying a water-stopping agent to the electric wire group in which the electric wires are arranged in parallel are performed after the parallel processing. A method of applying a water-stopping agent to an electric wire, wherein the application treatment is performed from below with respect to the electric wire group with a set of nozzle holes arranged at positions sandwiching both sides of the electric wire group to discharge the water-stopping agent. This is a method of applying a waterproofing agent to an electric wire, which is performed by discharging the waterproofing agent while moving upward.
Parallel arrangement processing in which a plurality of electric wires are arranged so as to overlap each other in the vertical direction, and water stoppage to the electric wires that are subjected to application treatment for applying a water-stopping agent to the electric wire group in which the electric wires are arranged in parallel after the parallel arrangement processing In the agent coating method, the juxtaposition processing is performed by distributing a plurality of bar-shaped comb-teeth members provided so as to be movable up and down above the position where the electric wires are arranged, and the coating treatment is performed with the water-stopping agent. Applying a water-stopper to a wire, which is performed by discharging a water-stopper while moving a pair of nozzle holes located at positions sandwiching both sides of the wire group from the bottom to the top. Is the method.

Another means is a water-stopping agent application device for an electric wire that applies a water-stopping agent to a necessary portion of a plurality of electric wires wired on the wiring board, the water-stopping agent on the wiring board A parallel arrangement means for obtaining a group of electric wires arranged in parallel so that the electric wires overlap in the vertical direction at a portion corresponding to the coated portion, and a water stop agent that moves up and down relative to the parallel arrangement means and toward the electric wire group A plurality of comb-shaped members having a bar shape, and the upper end portions of these comb-tooth members are detachably connected to each other, and the comb-tooth members at the upper end portions of the comb-tooth members Two tube bodies that have a lid member that closes the gap between them, and are provided so as to be able to be raised and lowered above the wiring board, and the discharge means is disposed at a position sandwiching both sides of the electric wire group, It is a water-stopper application device to an electric wire having an injection hole formed at the lower end of these tubular bodies.

  Note that “so as to overlap in the vertical direction” with respect to the electric wires does not mean that the peripheral surfaces of the electric wires are in contact with each other, but is an expression indicating the direction in which the electric wires are arranged.

  According to the said structure, while discharging a water stop agent from a pair of nozzle hole arrange | positioned in the position which pinches | interposes both sides of an electric wire group, a nozzle hole is moved to the upper side with respect to an electric wire group at the time of this discharge. For this reason, a water stop agent can be equally apply | coated with respect to the surrounding surface of each electric wire of an electric wire group irrespective of whether a part with an electric wire exists in the front of an injection hole. In addition, since the nozzle hole moves from the bottom to the upper side with respect to the electric wire group, it is possible to prevent the applied water-stopping agent from contacting the discharging means such as the nozzle hole.

  In addition, since the water-stopping agent is discharged from a set of nozzle holes that are arranged and moved on both sides of the wire group, even if the number of wires to which the water-stopping agent is applied changes, the range of movement of the nozzle holes can be reduced. If changed, it can be easily handled.

  Furthermore, if the juxtaposing means for performing the juxtaposing process for arranging a plurality of electric wires has a plurality of bar-like comb teeth members, it is possible to change the number of electric wires only by changing the number of comb teeth members. In addition, after the application process for applying the water-stopping agent, if the comb-tooth member is moved upward, the electric wire to which the water-stopping agent has been applied can be released. Interlocking with the discharge means for discharging the agent can be achieved. As a result, it is possible to simplify the configuration when the wire harness is manufactured in-line.

  As mentioned above, according to this invention, a water stop agent can be uniformly apply | coated with respect to each electric wire which comprises an electric wire group. For this reason, reliable water stop is realizable. In addition, the application of the water-stopping agent is performed while moving a pair of nozzle holes arranged on the left and right sides of the group of wires, so it is easy to cope with changes in the number of wires to which the water-stopping agent should be applied. Can do.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a front view showing a main part of a water-stopping agent application device 21 used when manufacturing a wire harness 11 (see FIG. 14), FIG. 2 is a side view thereof, FIG. 3 is a plan view thereof, FIG. 4 is a perspective view thereof.

  The water-stopping agent application device 21 is provided on a wiring board 22 for laying the electric wire 12, and a plurality of electric wires are provided so that a portion to which the grommet 13 (see FIG. 14) in the wire harness 11 is attached has water-stopping performance. This is for applying a water-stopping agent to 12 peripheral surfaces. The water stop agent is applied after the electric wires 12 are arranged vertically. For this reason, the water-stopping agent application device 21 includes a juxtaposed device 31 that vertically arranges a plurality of electric wires, and a discharge device 51 that discharges the water-stopping agent toward the electric wires arranged by the juxtaposed device 31.

  The juxtaposed device 31 is configured to form a plurality of electric wires 14 arranged in a line in the vertical direction so that a plurality of electric wires 12 overlap in the vertical direction, and in the illustrated example, three rows. 22, a base 32 fixed on the base 22, a detachable electric wire distributor 33 and a lower end position restricting tool 34 on the base 32, and a positioning tool 35 attached on the base 32.

  The base 32 has a trapezoidal shape having a top plate 32a having a dent at the center and leg portions 32b for supporting the top plate 32a, and a support plate 32c made of a magnetized metal is provided at the bottom of the dent. Is provided.

  As shown in FIG. 5, the wire distributor 33 detachably connects a plurality of bar-shaped comb teeth members 41 that are spaced apart from each other and the upper ends of the comb teeth members 41. It consists of a lid member 46 that closes the gap between the comb teeth members at the upper end of the member 41.

  Since the distribution of the electric wires 12 is performed so as to obtain three rows of electric wire groups 14 as described above, eight comb-tooth members 41 are used. That is, as shown in FIG. 3 and FIG. 4, a set of four comb teeth members 41 arranged so that the electric wires 12 can pass between each other are arranged at appropriate intervals in the direction in which the electric wires 12 are wound. Is done. The appropriate interval is a distance at which the water-stopping agent does not adhere to the comb-teeth member 41 even if the water-stopping agent is discharged at an intermediate position. In other words, the distance is longer than the length of the range in which the waterstop agent is applied.

  The comb-tooth member 41 is formed in a round bar shape, the lower end portion is formed so that the tip is thinner, and the lower end surface is formed flat. A magnet 42 that is attracted to the support plate 32c of the base 32 is embedded in the lower end portion. Further, the upper end portion of the comb-teeth member 41 has a tapered surface 43 at the corner portion of the upper end so as to be detachable from the lid member 46 as shown in FIG. It has a constricted portion 44 for reducing the size.

  The lid member 46 has a rectangular plate shape, and a window portion 47 penetrating in the vertical direction (thickness direction) is formed at an intermediate portion in the direction in which the electric wire 12 is wound. As shown in FIG. 3, the window 47 is formed longer than the width of the electric wire group 14 arranged in three rows, and a water-stopping agent is applied to the electric wire through the window 47.

  Further, in order to make the comb-tooth member 41 detachable, the lid member 46 has a hole portion 48 for receiving the upper end portion of the comb-tooth member 41 as shown in FIG. And an engagement plate 49 that engages with the constricted portion 44 of the member 41 to prevent it from coming off. That is, the hole 48 opened on the lower surface is formed at a position where the comb-tooth member 41 is to be disposed, and the engagement plate 49 is slidable in the lateral direction at an intermediate portion in the depth direction of the hole 48. Retained. The engaging plate 49 is formed with a through hole 49a that allows the upper end portion of the comb tooth member 41 to enter. When the upper end portion of the comb tooth member 41 is inserted into the hole portion 48, the inner peripheral edge of the through hole 49a is formed. It is urged | biased by the spring 46a toward one direction so that it may engage with the constriction part 44 of the comb-tooth member 41 (refer FIG. 5). In addition, an operation portion 49 b that protrudes from the end surface of the lid member 46 is formed at the end portion of the engagement plate 49 in the urging direction. When the operation portion 49b is pressed and the engagement plate 49 is pushed against the urging force of the spring 46a and displaced laterally, the through hole 49a of the engagement plate 49 and the hole portion 48 of the lid member 46 overlap each other. The member 41 can be separated from the lid member 46.

  By such an electric wire sorter 33, the electric wires 12 are divided into three rows of electric wire groups 14 as shown in FIG. 1, FIG. 3, and FIG. At this time, the lower end position restricting tool 34 is detachably attached to the upper surface of the base 32 in order to restrict the lower end position of the wire group 14 to a certain height.

  The lower end position restricting tool 34 is formed so as to surround the lower portion of the comb tooth member 41, and can be attached to and detached from the base 32 even when the comb tooth member 41 is set on the base 32 as shown in the figure. It is formed in a U shape in plan view. In other words, the upper ends of the two regulating plates 34a facing each other in the direction in which the electric wires 12 are bent do not lower the lower end position of the electric wires 12 passing between the comb teeth members 41 below the height of the regulating plates 34a. Yes. In addition, if it is the shape which can prevent the electric wire 12 falling, the lower end position control tool 34 may be shapes other than the said shape.

  Further, as shown in FIGS. 1, 2, and 3, the side surface portion of the base 32 is provided with a support rod 35a pivotally attached to the base end portion and a free end portion of the support rod 35a. A positioning tool 35 including a positioning plate 35b having a substantially square plate shape is attached. This positioning tool 35 is for indicating the position where the film 15 (see FIGS. 13 and 14) is wound around the electric wire 12, and is constant in the direction in which the electric wire 12 extends from the position of the water stop agent applied to the electric wire 12. It is attached to a portion corresponding to a position separated by a distance, and is formed so that the positioning plate 35b comes into light contact with the electric wire 12 when it is tilted toward the electric wire 12.

  The electric wire distribution tool 33 described above is detachably attached above the wiring board 22 in association with the discharge device 51 that discharges the water-stopping agent.

  That is, the discharge device 51 is supported by a support portion (not shown) above the wiring board 22 so as to be movable up and down and left and right with respect to the juxtaposed device 31, and moves up and down in conjunction with the support portion. It is attached to the raising / lowering part 61 (refer FIG. 7).

  The discharge device 51 is provided with two pipe bodies 52 for discharging the water-stopping agent, and nozzles for discharging the water-stopping agent are formed on opposite surfaces of the lower ends of the pipe bodies 52. 53 is provided. The interval between the tubular bodies 52 is set to an appropriate interval that faces the electric wire group 14, and when the water-stopping agent is discharged from the nozzle holes 53, the water-stopping agent adheres to the electric wires 12.

  As shown in FIG. 7, the elevating / lowering portion 61 has a plate shape in which a central portion is opened to allow the ejection device 51 to enter, and a pair of engaging / disengaging claws 62 are disposed on the lower surface thereof. These engaging / disengaging claws 62 are opened when they come down and come into contact with the juxtaposed means 31, and engage with the lid member 46 of the wire sorting tool 33. That is, it has the notch part 62a of the shape engaged with the right and left both sides of the cover member 46, and the inclined surface 62b which opens outside is formed in the lower side of this notch part 62a. Further, the two engaging / disengaging claws 62 are supported so as to be slidable in the left-right direction with respect to the lower surface of the elevating / lowering part 61, and these are rotatably connected by a connecting rod 63 pivotally attached to each other. The spring 64 attached to the collar 63 is biased in the direction of closing inward.

  When such an elevating part 61 descends and the inclined surface 62b of the engagement / disengagement claw 62 hits the lid member 46 of the electric wire sorter 33, the engagement / disengagement claw 62 opens to the left and right against the urging force, and further engages with further lowering. The notch 62 a of the claw 62 engages with the lid member 46. Further, when the lid member 46 is removed from the engagement / disengagement claw 62, at least one of the engagement / disengagement claws 62 may be moved in the left-right direction to separate the engagement / disengagement claw 62 from the lid member 46. In order to facilitate the operation of opening the engagement / disengagement claw 62 to the left and right, the connection rod 63 is provided with an operation lever 65 for widening the angle of the connection rods 63 pivoted to each other.

  The lifting / lowering unit 61 provided with the engagement / disengagement claw 62 descends at an appropriate timing when the support unit supporting the discharge device 51 descends and rises at an appropriate timing when the support unit rises. Is set as follows.

  As shown in FIGS. 2 and 3, receiving devices 71 for receiving the electric wires 12 are attached to both sides of the juxtaposed device 31 on the wiring board 22 in the front-rear direction (direction in which the electric wires 12 are bent). Yes. The receptacle 71 is for supporting the plurality of electric wires 12 at a predetermined height, and does not need a function of distributing the electric wires 12. For this reason, the thing of the shape similar to a well-known receiving tool which has the support | pillar 71b and the receiving part 71a which makes | forms the U-shape attached to the upper end of this support | pillar 71b may be sufficient.

  Application of the water-stopping agent using the water-stopping agent application device 21 configured as described above is performed as follows.

  First, a side-by-side process for arranging a plurality of electric wires 12 is performed. In this example, the juxtaposition processing is performed so as to form three groups of electric wires 14 in which the electric wires 12 are arranged in a row in the vertical direction as described above. Prior to arranging the electric wires 12, the comb teeth member 41 and the lid member The electric wire distributor 33 integrated with 46 is fixed to the base 32. Subsequently, the lower end position restricting tool 34 is attached to the base 32. Next, the cover member 46 of the electric wire distribution tool 33 is removed, and the electric wires 12 to be wired are appropriately distributed so as to fit between the comb teeth members 41 as shown in FIG. . After the electric wires 12 are distributed, the lid member 46 is attached to the comb-teeth member 41 and integrated.

  The portions of the electric wires 12 on both the front and rear sides of the juxtaposed device 31 are received by the receiver 71, and the other portions are wired as desired.

  The electric wires 12 arranged side by side in the juxtaposition device 31 are arranged in a line in each row and the lower end position of the electric wire group 14 is restricted by the lower end position restricting tool 34, so that the electric wires 12 are higher than the height of the lower end position restricting tool 34. Will not go down. Moreover, since the upper end position of the electric wire group 14 is closed by the lid member 46, the electric wires 12 do not spill from the juxtaposed device 31 even if the electric wires 12 are slack.

  After making such a state, the application | coating process which apply | coats a water stop agent with respect to each electric wire group 14 is performed.

  The coating process is performed by lowering the ejection device 51. When the discharge device 51 is lowered, the two pipe bodies 52 of the discharge device 51 are lowered so as to sandwich the wire group 14 in a predetermined row among the three rows of the wire group 14 to the left and right. Lower to a predetermined position below the lower end position.

  As the discharge device 51 is lowered, the elevating part 61 is lowered at an appropriate timing set in advance, and the engagement / disengagement claw 62 of the elevating part 61 is engaged with the lid member 46 of the electric wire sorting tool 33 to be integrated.

  From this state, the discharging device 51 is moved up and down and left and right to apply the water-stopping agent in order to the three rows of electric wire groups 14 as shown in FIG.

  Specifically, the water-stopping agent is applied as shown in FIG. Since the nozzle holes 53 formed in the lower end portion of the tube body 52 of the discharge device 51 are set so that their directions are opposed to each other, the water stop agent discharged from the pair of nozzle holes 53 is the electric wire 12. And scattered on the peripheral surface of the electric wire 12. As the water stop agent 16 is discharged from the nozzle hole 53, the discharge device 51 moves upward, so that the electric wire group 14 is sequentially directed from the electric wire 12 located at the lower end to the electric wire 12 located thereabove. Is applied. The nozzle hole 53 extends from a position corresponding to the curved surface portion at the lower end of the electric wire 12 to a position corresponding to a diameter portion where the distance from the nozzle hole is opposed to the nozzle hole 53 and further to the curved surface portion at the upper end of the electric wire 12. It applies in order so that the corresponding position and the peripheral surface of each electric wire 12 may be licked. Thus, since the position of the nozzle hole 53 moves with the discharge of the water-stopping agent 16, the application can be performed evenly and the application can be performed without unevenness. Moreover, since the water-stopping agent is discharged mechanically, the water-stopping agent 16 is discharged at a constant momentum. Also from this point, the occurrence of coating unevenness can be prevented.

  After applying the water-stopping agent to one wire group 14 in this way, the discharge device 51 is moved in the left-right direction, and the discharge device 51 is lowered below the lower end position of another wire group 14. The application is sequentially performed in the same manner as described above.

  And after applying the water stop agent 16 to all the electric wire groups 14, as shown in FIG. 11, the electric wire distribution tool 33 of the juxtaposition device 31 is moved to an upper retreat position, and an electric wire is released. Perform release processing. That is, when the discharge device 51 is raised after the application of the waterstop agent is completed, the elevating unit 61 is also raised at an appropriate timing. As the elevating part 61 rises, the electric wire sorter 33 coupled to the engagement / disengagement claw 62 also rises, and the electric wire 12 is completely released as shown in FIG.

  Next, a finishing process such as sheet winding is performed on the electric wire 12 to which the water stop agent 16 is applied. First, the fully opened electric wires 12 are collected by hand so that the operator bundles them, and the positioning tool 35 is tilted toward the electric wires 12. At this time, the lower end position restricting tool 34 can be removed as necessary.

  When the positioning tool 35 is tilted, the positioning plate 35b comes into light contact with the electric wire 12 as shown in FIG. 13, so that the film 15 is wound along the positioning plate 35b. Next, the adhesive tape 17 is wound on the bundled electric wires 12 by winding the film 15. The adhesive tape 17 is applied to both sides of the film 15 as shown in FIG. 14 and tightened to prevent the water-stopping agent 16 from protruding. Finally, the grommet 13 is attached and fixed with the adhesive tape 18.

  As described above, since the water stopping agent 16 can be applied evenly and evenly to all the electric wires 12, it is possible to realize reliable water stopping. Moreover, the pair of nozzle holes 53 moves from the bottom to the top with respect to the electric wire group 14 during application. For this reason, it is possible to prevent the applied water-stopping agent and the discharging means such as the injection holes 53 from accidentally contacting each other, ensuring a uniformly applied state and contributing to reliable water-stopping.

  Further, when the number of the electric wires 12 constituting the wire harness 11 is changed, the setting of the moving distance and range of the discharge device 51 may be changed, or the height of the lower end position restricting tool 34 may be changed. If there is a significant change in the number of the electric wires 12 and it becomes necessary to change the number of the electric wire groups 14, the number of the comb-tooth members 41 may be changed. Since the application of the water-stopping agent by the discharge device 51 is performed by discharging the water-stopping agent from the pair of nozzle holes 53, it is not necessary to change the discharge device 51 side. For this reason, it can respond easily even if the number of electric wires changes.

  Furthermore, after the application process for applying the water-stopping agent, when the electric wire sorter 33 is raised, the electric wire 12 becomes free, so that the subsequent process can be performed as it is. Moreover, since the rise of the wire sorting tool 33 is linked with the rise of the discharge device 51, it is not necessary to provide another drive device, and the configuration of the entire device can be simplified.

  In addition, since the wire sorting tool 33 is mechanically raised, the wire sorting tool 33 passes a predetermined track when it is lifted. For this reason, the electric wire distribution tool 33 can be accurately raised without being swayed from side to side. As a result, unlike the case where the electric wire distributor 33 is manually removed, it is possible to prevent the electric wire distributor 33 from coming into contact with the water-stopping agent and reducing the amount of the water-stopper applied, and the occurrence of water-stopping failure. Can be prevented.

  Moreover, since the positioning device 35 is provided in the juxtaposed device 31 and the winding position of the film 15 can be clearly indicated, even if there is a difference in conditions when winding the film 15, such as differences in workers, It is possible to wind the film 15 at an accurate position. This also makes it possible to eliminate the water stop failure.
