Description

[Technical Field]

[0001] The present invention relates to a sheathing attachment device for attaching a tubular sheathing to an electric wire. [Background technology]

[0002] Conventionally, in the manufacture of wire harnesses, for example, to protect electric wires, tubular exterior materials such as twisted tubes and corrugated tubes have been widely used, which are attached to electric wires while holding the electric wires inside through slits provided in the peripheral wall. In many cases, such exterior materials are attached by pushing the electric wires through the slits in the peripheral wall, and a device for performing such a task has been proposed (see, for example, Patent Document 1). In the device described in Patent Document 1, the exterior material is set so as to fit along the electric wires, and the electric wires are sequentially guided inside the exterior material, thereby attaching the exterior material to the electric wires.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2017-001884 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, automation of wire harness manufacturing operations, including the attachment of exterior materials, has been progressing. In the device described in Patent Document 1, the exterior material is set so as to align with the electric wires, but the following issue can be an obstacle when attempting to automate a series of operations including the setting of such exterior materials. That is, the exterior material needs to be received from a predetermined conveying device, but the receiving direction that is convenient for receiving the exterior material often does not match the extending direction of the electric wires, and this mismatch of directions can be an obstacle to automation.

[0005] Therefore, the present invention has been made in view of the above-mentioned problems, and has as its object to provide an external material attachment device that can receive an external material in a receiving direction different from the extending direction of the electric wire and attach it to the electric wire. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, the external material mounting device includes a receiving section that receives, in a receiving direction along the longitudinal direction, an external material that is tubular and is to be attached to an electric wire while storing the electric wire inside the receiving section through a slit provided in a peripheral wall, a guide section that is provided on the front side of the receiving section in the receiving direction and extends linearly in an inclined direction that is inclined at a predetermined angle with respect to the receiving section, and that guides the external material received by the receiving section from the receiving direction to the inclined direction, and a guide section that guides the external material guided in the inclined direction by the guide section. The conveying unit is characterized by comprising: a conveying unit that further sends the outer casing material forward in the inclined direction; a first frame unit on which the receiving unit, the guide unit, and the conveying unit are mounted; a rotating unit that rotates the first frame unit about a rotation axis that is perpendicular to both the receiving direction and the inclined direction, between a first position in which the receiving unit can receive the outer casing material and a second position in which the guide unit can align with the electric wires that are arranged in a straight line; and a second frame unit that is installed at a predetermined installation location and on which the first frame unit and the rotating unit are mounted. [Effects of the Invention]

[0007] According to the above-described external material attachment device, it is possible to receive and attach an external material to an electric wire in a receiving direction different from the extending direction of the electric wire. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] An embodiment of the exterior material mounting device will be described below.

[0010] Fig. 1 is a perspective view showing an external material mounting device according to one embodiment. Fig. 2 is a side view of the external material mounting device shown in Fig. 1, as seen from the direction of arrow V11 in Fig. 1.

[0011] The external material attachment device 1 of this embodiment is a device that automatically attaches a twist tube W12 to an electric wire W11 as an external material for protecting the electric wire W11 during the manufacture of a wire harness W1. The twist tube W12 is a resin member formed by rolling a sheet-like material into a tube shape so that the circumferential ends overlap each other, and the gap between the overlapping ends serves as a slit provided in the peripheral wall for accommodating the electric wire W11 inside. The twist tube W12 is attached to the electric wire W11 while accommodating the electric wire W11 inside through the slit in the peripheral wall.

[0012] This exterior material mounting device 1 is also a device for attaching a twist tube W12 to an electric wire W11 that is arranged linearly in a vertical direction D11 along the force of gravity. On the electric wire W11 side, at the feed destination of the twist tube W12, a tape winding mechanism M1 is installed to secure the feed end of the twist tube W12 to the electric wire W11.

[0013] The exterior material mounting device 1 comprises a receiving section 11, a guide section 12, a conveying section 13, a first frame section 14, a rotating section 15, a second frame section 16, a moving section 17 for moving toward and away from the wire, and a moving section 18 for moving in the electric wire direction.

[0014] The receiving unit 11 is a cylindrical portion that receives the twisted tube W12 in a receiving direction D12 that is aligned with its longitudinal direction. The twisted tube W12 transported in the receiving direction D12 is fed into this cylindrical receiving unit 11. The guide unit 12 is provided on the front side of the receiving unit 11 in the receiving direction D12 so as to extend linearly in an inclined direction D13 that is inclined at a predetermined angle (approximately 45° in this embodiment) with respect to the receiving unit 11. This guide unit 12 serves to guide the twisted tube W12 received by the receiving unit 11 from the receiving direction D12 to the inclined direction D13. The conveying unit 13 is a portion that further sends the twisted tube W12 guided in the inclined direction D13 by the guide unit 12 forward in the inclined direction D13 by the rotation of conveying rollers 131. The first frame portion 14 is a metal frame on which the receiving portion 11, the guide portion 12, and the transport portion 13 are mounted.

[0015] The swivel unit 15 is a mechanical part that rotates the first frame unit 14, on which the above-described components are mounted, in a rotation direction D14 about a rotation axis 15a as follows. The rotation axis 15a is an axis that is perpendicular to both the receiving direction D12 of the receiving unit 11 and the inclination direction D13 of the guide unit 12. The swivel unit 15 rotates the first frame unit 14 between a first position P11, in which the receiving unit 11 can receive the twisted tube W12, and a second position P12, in which the guide unit 12 can be aligned with the linearly arranged electric wire W11. In this embodiment, since the inclination angle of the guide unit 12 is approximately 45°, the rotation angle between the first position P11 and the second position P12 is also approximately 45°. The swivel unit 15 has a cylinder mechanism 151 that swivels the first frame unit 14 about the swivel shaft 15a by linearly pushing and pulling a part of the first frame unit 14 that is journalled on the swivel shaft 15a.

[0016] The second frame section 16 is a metal frame installed at a predetermined installation location and on which the first frame section 14 and the swivel section 15 are mounted. The second frame section 16 is configured by combining multiple rectangular columnar frame members 161. In this embodiment, the first frame section 14 and the swivel section 15 are attached to a later-described approaching and separating movement section 17, which is attached to a later-described electric wire direction movement section 18. The electric wire direction movement section 18 is then attached to one of the frame members 161 in the up-down direction D11 of the second frame section 16. That is, in this embodiment, the first frame section 14 and the swivel section 15 are mounted on the second frame section 16 via the approaching and separating movement section 17 and the electric wire direction movement section 18, and the approaching and separating movement section 17 is mounted on the second frame section 16 via the electric wire direction movement section 18. The electric wire direction movement section 18 is directly mounted on the second frame section 16.

[0017] As described above, the approaching / separating moving unit 17 is mounted on the second frame unit 16 via the electric wire direction moving unit 18 and is a mechanical component that moves the first frame unit 14 in the following approaching / separating direction D15. The approaching / separating direction D15 is a direction perpendicular to both the electric wires W11 linearly arranged in the vertical direction D11 and the pivot shaft 15a. The approaching / separating moving unit 17 slides the first frame unit 14 in this approaching / separating direction D15 between a separation position P13 (FIG. 3) and a contact position P14 (FIG. 3) relative to the electric wire W11. The separation position P13 is a position of the first frame unit 14 where the guide unit 12 is separated from the electric wire W11 even when the first frame unit 14 assumes the second posture P12. The contact position P14 is a position of the first frame unit 14 where the guide unit 12 contacts the electric wire W11 after the first frame unit 14 assumes the second posture P12. The approaching and separating moving part 17 has an approaching and separating rail part 171 attached to the electric wire direction moving part 18, and an approaching and separating movable part 172 held by the approaching and separating rail part 171 in a state where it can slide in the approaching and separating direction D15. The first frame part 14 and the swivel part 15 are attached to the slidable approaching and separating movable part 172.

[0018] At this time, the attachment of the first frame portion 14 to the approaching / separating movable portion 17, i.e., the attachment of the first frame portion 14 to the second frame portion 16, is an attachment that allows for reversible attachment as follows. First, the receiving portion 11 mounted on the first frame portion 14 receives the twisted tube W12 in the receiving direction D12, which is a horizontal direction perpendicular to both the electric wires W11 arranged linearly in the vertical direction D11 and the pivot axis 15a. Then, the attachment of the first frame portion 14 to the second frame portion 16 allows for reversal of the first frame portion 14 by 180° about the reversal axis 14a along the receiving direction D12. The receiving portion 11 is held by the first frame portion 14 so that it can receive the twisted tube W12 in the receiving direction D12 both before and after the first frame portion 14 is reversed. The guide portion 12 is held by the first frame portion 14 so that the guide portion 12 can be aligned with the electric wire W11 by rotating the rotating portion 15 both before and after the first frame portion 14 is turned over. The guide portion 12 is held by the first frame portion 14 so that it guides the twist tube W12 toward one end of the electric wire W11 before the electric wire W11 is turned over and toward the other end after the electric wire W11 is turned over. FIGS. 1 and 2 show the first frame portion 14 attached so that the guide portion 12 guides the twist tube W12 toward the upper end of the electric wire W11, which is linearly arranged in the vertical direction D11. When the first frame portion 14 is turned over 180° about the turning axis 14a and replaced, the guide portion 12 assumes a position that guides the twist tube W12 toward the lower end of the electric wire W11.

[0019] As described above, the electric wire direction moving unit 18 is mounted directly on the frame material 161 of the second frame unit 16, and moves the first frame unit 14 in the electric wire direction D16 via the approaching and separating moving unit 17. The electric wire direction D16 is a direction along the electric wires W11 arranged in a straight line (in this embodiment, the up-down direction D11). The electric wire direction moving unit 18 has an electric wire direction rail unit 181 that extends in the electric wire direction D16 and is attached to the frame material 161, and an electric wire direction movable unit 182 that is slidably held on the electric wire direction rail unit 181. The approaching and separating moving unit 17 is attached to the slidable electric wire direction movable unit 182.

[0020] Next, a series of operations from when the twist tube W12 is received by the receiving section 11 until when it is sent out to the electric wire W11 in the external exterior material attaching device 1 of this embodiment will be described.

[0021] Figure 3 is a diagram showing the first half of a series of operations from when the twist tube is received at the receiving section until it is sent out to the electric wire in the external material attachment device shown in Figures 1 and 2. Also, Figure 4 is a diagram showing the second half of a series of operations following the operations in Figure 3 from when the twist tube is received at the receiving section until it is sent out to the electric wire in the external material attachment device shown in Figures 1 and 2.

[0022] First, in step S11 of Figure 3, the twist tube W12 is received by the exterior material mounting device 1. In this receiving stage of step S11, the approaching / separating moving unit 17 positions the first frame unit 14 in the approaching / separating direction D15 at a separated position P13 where the guide unit 12 is separated from the electric wire W11. The swiveling unit 15 also sets the first frame unit 14 to a first position P11 that allows the receiving unit 11 to receive the twist tube W12. The receiving unit 11, which is oriented horizontally in this first position P11, receives the twist tube W12 in the horizontal receiving direction D12. Note that at this stage, the guide unit 12 is tilted toward the horizontal side with respect to the electric wire W11.

[0023] Once the twist tube W12 has been received by the exterior material mounting device 1, in the next step S12, the turning unit 15 turns the first frame unit 14 in the guide upward direction D141 of the turning direction D14 about the turning axis 15a to set it to the second position P12. The guide upward direction D141 is the direction in which the guide unit 12 is raised upward to align with the electric wire W11. During the turning stage of this step S12, the first frame unit 14 is still positioned at the separated position P13, and the guide unit 12 is in a position separated from and aligned with the electric wire W11.

[0024] In step S13 following the rotation of the first frame portion 14 by the rotating unit 15, the approaching / separating moving unit 17 slides the first frame portion 14, which has been rotated to the second posture P12, in the electric wire approaching direction D151 of the approaching / separating direction D15. The electric wire approaching direction D151 is a direction in which the guide portion 12 approaches the electric wire W11. By sliding in this electric wire approaching direction D151, the first frame portion 14 is positioned at a contact position P14 where the guide portion 12 contacts the electric wire W11. Note that in this embodiment, the feeding destination of the twist tube W12 is a position where the feeding end of the twist tube W12 is fixed around the electric wire W11 by the tape winding mechanism M1. During the approaching stage of step S14, the guide portion 12 is positioned below the tape winding position P15 by the tape winding mechanism M1.

[0025] In step S14 following the sliding movement of the first frame portion 14 by the approaching / separating moving portion 17, the tape winding mechanism M1 winds the tape M11 around the tape winding position P15 on the electric wire W11. In this electric wire tape winding stage of step S14, the tape M11 is wound around the tape winding position P15, which is spaced above the guide portion 12.

[0026] In step S15 following the tape winding around the electric wire W11 by the tape winding mechanism M1, the first frame portion 14 is slid in the upward direction D161 in the electric wire direction D16 by the electric wire direction moving portion 18. During this upward movement stage in step S15, the tip end of the guide portion 12 is brought close to a position adjacent to the tape M11 wound around the tape winding position P15.

[0027] In step S16 following the lifting of the first frame unit 14 by the electric wire direction moving unit 18, the conveying unit 13 feeds out the twist tube W12. In this feeding stage of step S16, the twist tube W12 received by the receiving unit 11 is guided upward by the guide unit 12 and fed out so as to house the electric wire W11 inside. This feeding is performed so that the feeding end of the twist tube W12 overlaps the widthwise middle portion of the tape M11 at the tape winding position P15. Then, in a stage (not shown) following step S16, the tape winding mechanism M1 winds the feeding end of the twist tube W12 together with the tape, and the twist tube W12 is attached to the electric wire W11 with the feeding end fixedly wound with the tape.

[0028] The installation of the twist tube W12 shown in Figures 3 and 4 is performed by receiving the twist tube W12 in the horizontal receiving direction D12 and guiding it toward the upper end of the electric wire W11 using the guide portion 12. In contrast, with the external material installation device 1 of this embodiment, it is also possible to install the twist tube W12 by guiding it toward the lower end of the electric wire W11 using the guide portion 12, in the opposite direction to the installation example shown in Figures 3 and 4. In this case, in the external material installation device 1, the first frame portion 14 is reversed and replaced around the above-mentioned reversal axis 14a.

[0029] Figure 5 is a diagram showing how the first frame has been reversed and replaced in the exterior material mounting device shown in Figures 1 to 4. Step S21 in Figure 5 shows how the first frame portion 14, which has been reversed and replaced, is set to a first posture P11 by the swiveling portion 15 and positioned to a separated position P13 by the approaching and separating movement portion 17. Step S22 in Figure 5 shows how the first frame portion 14 is set to a second posture P12 by the swiveling portion 15. Note that in step S22, the first frame portion 14 remains positioned at the separated position P13.

[0030] In this embodiment, the reversal replacement is performed by an operator first removing the first frame portion 14 of the external material mounting device 1 from the approaching and retracting movable portion 17, then reversing it 180° around the reversal axis 14a and attaching it to the approaching and retracting movable portion 17. This reversal replacement causes the guide portion 12 to extend in the opposite direction from before reversal. However, the receiving portion 11 faces the horizontal receiving direction D12 both before and after reversal, and can receive the twist tube W12 in this horizontal receiving direction D12 unchanged before and after reversal. On the other hand, because the guide portion 12 extends in the opposite direction from before reversal, when the first frame portion 14 is rotated as in step S22, the guide portion 12 follows the electric wire W11 in a position that guides the twist tube W12 downward, in the opposite direction from before reversal. Furthermore, since the portion of the first frame portion 14 pushed and pulled by the cylinder mechanism 151 of the swivel unit 15 is now upside down as viewed from the cylinder mechanism 151 compared to before the reversal, the direction of rotation of the first frame portion 14 by the swivel unit 15 is also opposite to that before the reversal. That is, the rotation after the reversal is in the guide downward direction D142, which is the rotation direction D14 about the rotation shaft 15a and raises the guide portion 12 downward to align it with the electric wire W11. After step S22, operations similar to steps S13 to S16 in FIGS. 3 and 4 are performed. Through these operations, the twist tube W12 is fed toward the lower end of the electric wire W11, with the tape winding position P16 on the lower end side being the feeding destination by the tape winding mechanism M1 arranged on the lower end side of the electric wire W11, and the twist tube W12 is attached to the electric wire W11.

[0031] According to the external material mounting device 1 of the embodiment described above, first, by setting the first frame portion 14 to the first position P11, the twist tube W12 is received by the receiving portion 11 in the receiving direction D12 along its longitudinal direction. Then, by rotating the first frame portion 14 to the second position P12 and aligning the guide portion 12 along the electric wire W11, the twist tube W12 is guided along the electric wire W11 by the guide portion 12. In this guided state, the twist tube W12 can be fed out by the conveying portion 13 and attached to the electric wire W11. In other words, according to this embodiment, the twist tube W12 can be received and attached to the electric wire W11 in the receiving direction D12, which is different from the extension direction of the electric wire W11.

[0032] In this embodiment, the electric wires W11 are arranged linearly in the vertical direction D11 along the force of gravity, and the second orientation P12 of the first frame portion 14 is an orientation in which the guide portion 12 extends in the vertical direction D11. With this configuration, the twist tube W12 can be suitably attached to the electric wires W11 that are arranged linearly in the vertical direction D11, such that the installation area along the horizontal plane is significantly smaller than when the electric wires are placed horizontally.

[0033] Furthermore, in this embodiment, the swivel unit 15 has a cylinder mechanism 151 that swivels the first frame unit 14 by linearly pushing and pulling a portion of the first frame unit 14 that is journaled on the swivel shaft 15a. With this configuration, by using the cylinder mechanism 151 that is suitable for movement between two states, namely, between the first position P11 and the second position P12, the first frame unit 14 can be swiveled at lower costs than when, for example, a servo motor is used.

[0034] In this embodiment, the first frame portion 14 can be rotated 180° around the reversal axis 14a for reassembly. The receiving portion 11 can receive the twist tube W12 in the receiving direction D12 both before and after reversal. The guide portion 12 can be rotated by the rotating portion 15 to align the guide portion 12 with the electric wire W11 both before and after reversal. Furthermore, the guide portion 12 is held by the first frame portion 14 so as to guide the twist tube W12 toward one end of the electric wire W11 before reversal and toward the other end after reversal. This configuration allows the first frame portion 14 to be rotated relative to the second frame portion 16, thereby guiding the twist tube W12 to either end of the electric wire W11. Furthermore, the receiving portion 11 can receive the twist tube W12 in the common receiving direction D12. By adopting such a replacement configuration, there is no need to prepare two devices suitable for one end and the other end of the electric wire W11, and the manufacturing cost for attaching the twist tube W12 can be significantly reduced.

[0035] Furthermore, in this embodiment, an approaching / separating moving unit 17 is provided that moves the first frame portion 14 in a direction D15 toward or away from the electric wire W11. The approaching / separating moving unit 17 moves the first frame portion 14 between a separated position P13 where the guide portion 12 is separated from the electric wire W11 in the second posture P12, and a contact position P14 where the guide portion 12 is in contact with the electric wire W11 in the second posture P12. According to this configuration, by positioning the first frame portion 14 at the separated position P13, the first frame portion 14 can be rotated in a favorable state where the guide portion 12 is separated from the electric wire W11 and interference is suppressed.

[0036] In addition, in this embodiment, an electric wire direction moving unit 18 is provided that moves the first frame unit 14 in the electric wire direction D16 along the linearly arranged electric wires W11. According to this configuration, by moving the first frame unit 14 with the electric wire direction moving unit 18, the guide unit 12 can be positioned so that the twist tube W12 can be fed toward any location in the electric wire direction D16.

[0037] It should be noted that the above-described embodiment merely shows a typical form of the external material mounting device, and the external material mounting device is not limited to this and can be implemented in various modifications.

[0038] For example, in the above-described embodiment, an external material attachment device 1 that attaches a twisted tube W12 as an external material to an electric wire W11 is exemplified as an example of an external material attachment device. However, the external material attachment device is not limited to this. The external material to be attached may be any other external material, such as a corrugated tube, as long as it is tubular and can be attached to the electric wire while containing the electric wire inside through a slit provided in the peripheral wall.

[0039] Furthermore, in the above-described embodiment, an example of an exterior material mounting device is given as an exterior material mounting device 1 in which each component part is mounted to a second frame part 16 made up of a combination of multiple frame materials 161. However, the exterior material mounting device is not limited to this, and any specific frame configuration can be adopted for the second frame, etc.

[0040] In the above-described embodiment, an example of an external material attachment device is an external material attachment device 1 in which the destination of the twist tube W12 as an external material is the tape winding position P15 of the tape winding mechanism M1 on the electric wire W11. However, the external material attachment device is not limited to this, and any specific destination of the external material on the electric wire is not important.

[0041] Furthermore, in the above-described embodiment, an exterior material mounting device 1 in which the guide section 12 is inclined at an angle of approximately 45° relative to the receiving section 11 is exemplified as an example of an exterior material mounting device. In this exterior material mounting device 1, the swiveling section 15 swivels the first frame section 14 at a swiveling angle of approximately 45° between the first position P11 and the second position P12 in accordance with this angle of tilt. However, the exterior material mounting device is not limited to this, and the angle of tilt of the guide section and the corresponding swiveling angle by the swiveling section can be set to any angle.

[0042] Furthermore, in the above-described embodiment, as an example of an external material installation device, an external material installation device 1 is exemplified in which the electric wires W11 are arranged linearly in the vertical direction D11 and the second position P12 of the first frame portion 14 is an orientation in which the guide portions 12 extend in the vertical direction D11. However, the external material installation device is not limited to this, and the electric wires may be arranged horizontally. In this case, the second position of the first frame portion is an orientation in which the guide portions extend horizontally. However, as described above, by arranging the electric wires W11 in the vertical direction D11 and extending the guide portions 12 in the second position P12 in the vertical direction D11, the installation area for the electric wires W11 can be significantly reduced while still allowing the twist tubes W12 to be installed satisfactorily.

[0043] Furthermore, in the above-described embodiment, the rotating unit 15 having the cylinder mechanism 151 that rotates the first frame unit 14 is exemplified as an example of the rotating unit. However, the rotating unit is not limited to this, and may be, for example, one that rotates the first frame using a servo motor. However, as described above, by using the cylinder mechanism 151, it is possible to rotate the first frame unit 14 at a reduced cost.

[0044] Furthermore, in the above-described embodiment, an exterior material installation device 1 capable of reversible replacement of the first frame portion 14 is exemplified as an example of an exterior material installation device. In this exterior material installation device 1, the receiving portion 11 can receive the electric wire W11 in the receiving direction D12 both before and after reversal, and the guide portion 12 can be aligned with the electric wire W11 by rotating. The guide portion 12 guides the twist tube W12 to one end of the electric wire W11 before reversal and to the other end after reversal. However, the exterior material installation device is not limited to this. It may be one in which the first frame portion cannot be reversed and the receiving direction of the receiving portion and the guiding direction of the guide portion are uniquely determined. Alternatively, it may be one in which the first frame portion can be reversed and the receiving direction of the receiving portion and the guiding direction of the guide portion both change before and after reversal. However, as mentioned above, if the first frame portion 14 can be reversed and replaced, and the receiving direction D12 remains the same before and after reversal, but the guiding direction changes to the opposite direction, the manufacturing costs for installing the twist tube W12 can be significantly reduced.

[0045] Furthermore, in the above-described embodiment, an example of an external material mounting device is an external material mounting device 1 provided with a moving unit 17 that moves the first frame portion 14 between the separated position P13 and the contact position P14 relative to the electric wire W11. However, the external material mounting device is not limited to this, and may be configured in such a way that the guide portion does not particularly move toward or away from the electric wire. However, as described above, by providing the moving unit 17, the first frame portion 14 can be rotated in a favorable state in which the guide portion 12 is separated from the electric wire W11 and interference is suppressed.

[0046] Furthermore, in the above-described embodiment, an external material mounting device 1 provided with an electric wire direction moving unit 18 that moves the first frame unit 14 in the electric wire direction D16 along the electric wire W11 is exemplified as an example of an external material mounting device. However, the external material mounting device is not limited to this, and may be configured not to specifically move the first frame unit in the electric wire direction. However, as described above, by providing the electric wire direction moving unit 18, it is possible to position the guide unit 12 so that the twist tube W12 can be fed toward any location in the electric wire direction D16.
