Description

Technical Field

[0001] The present invention relates to an exterior member mounting device for attaching a tubular exterior member to an electric wire.

Background Art

[0002] Conventionally, in the manufacture of wire harnesses, for the protection of electric wires and the like, exterior members that are tubular and are attached to the electric wires while accommodating the electric wires inside through slits provided in the peripheral wall, such as twist tubes and corrugated tubes, are widely used. In many cases, the attachment of such exterior members is performed by operations such as pushing the electric wire through the slit in the peripheral wall. However, a device for performing such operations has been proposed (for example, see Patent Document 1). In the device described in this Patent Document 1, the exterior member is set along the electric wire, and the electric wire is sequentially guided inside the exterior member so that the exterior member is attached to the electric wire.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In recent years, the automation of wire harness manufacturing operations, including the operation of attaching exterior members, has been promoted. At this time, in the device described in Patent Document 1, the exterior member is set along the electric wire. However, when attempting to automate a series of operations including the setting of such an exterior member, the following points may become obstacles. That is, it is necessary to receive the exterior member from a predetermined conveying device. However, often the favorable receiving direction for receiving the exterior member does not coincide with the extending direction of the electric wire, and the mismatch between these directions may become an obstacle to automation.

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

[0006] To solve the above problems, the exterior material mounting device includes a receiving section that receives exterior material attached to electric wires in a tubular shape with slits provided in the peripheral wall, while housing the electric wires inside, in a receiving direction along the longitudinal direction thereof; a guide section provided on the front side of the receiving section in the receiving direction, extending linearly in an inclined direction at a predetermined angle relative to the receiving section, and guiding the exterior material received by the receiving section from the receiving direction to the inclined direction; and the exterior material guided in the inclined direction by the guide section. The device is characterized by comprising: a conveying unit that further sends the 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 swivel unit that rotates the first frame unit between a first position in which the receiving unit can receive the exterior material and a second position in which the guide unit can be aligned with the linearly arranged electric wires, with the swivel unit centered on a swivel axis perpendicular to both the receiving direction and the inclined direction; and a second frame unit installed at a predetermined installation location on which the first frame unit and the swivel unit are mounted. [Effects of the Invention]

[0007] According to the above-described exterior material attachment device, the exterior material can be received and attached to the electric wire in a receiving direction different from the direction in which the electric wire extends. [Brief explanation of the drawing]

[Figure 2] This is a side view of the exterior material mounting device shown in Figure 1, viewed from the direction of arrow V11 in Figure 1. [Figure 3]Figures 1 and 2 show the first half of the sequence of operations in the exterior material mounting device, from when the twisted tube is received at the receiving section until it is sent out to the electric wire. [Figure 4] This figure shows the second half of the sequence of operations in the exterior material mounting device shown in Figures 1 and 2, from when the twisted tube is received at the receiving section until it is sent to the electric wire, following the operation shown in Figure 3. [Figure 5] Figures 1 to 4 show the process of reversing and reattaching the first frame in the exterior material mounting device. [Modes for carrying out the invention]

[0009] The following describes one embodiment of an exterior material mounting device.

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

[0011] The exterior material attachment device 1 of this embodiment is a device that automatically attaches a twisted tube W12 to an electric wire W11 as an exterior material for protecting the electric wire W11 during the manufacturing of a wire harness W1. The twisted tube W12 is a resin member in which a sheet-like material is rolled into a tube shape so that its circumferential ends overlap, and the gap between the overlapping ends acts as a slit provided in the circumferential wall to accommodate the electric wire W11 inside. The twisted tube W12 is attached to the electric wire W11 while accommodating the electric wire W11 inside through this slit in the circumferential wall.

[0012] Furthermore, this exterior material attachment device 1 is a device for attaching twisted tubes W12 to electric wires W11 that are arranged linearly in the vertical direction D11 along gravity. On the electric wire W11 side, a tape winding mechanism M1 is installed at the feed point of the twisted tube W12 to secure the feed end of the twisted tube W12 to the electric wire W11.

[0013] The exterior material mounting device 1 includes a receiving section 11, a guide section 12, a transport section 13, a first frame section 14, a rotating section 15, a second frame section 16, an approaching / disengaging movement section 17, and a wire direction movement section 18.

[0014] The receiving section 11 is a cylindrical part that receives the twisted tube W12 in a receiving direction D12 along its longitudinal direction. The twisted tube W12 that has been transported in the receiving direction D12 is fed into this cylindrical receiving section 11. The guide section 12 is a part that extends linearly in an inclined direction D13, which is inclined at a predetermined angle (approximately 45° in this embodiment) relative to the receiving section 11, on the front side of the receiving direction D12. The guide section 12 plays the role of guiding the twisted tube W12 received by the receiving section 11 from the receiving direction D12 to the inclined direction D13. The transport section 13 is a part that further transports the twisted tube W12, which has been guided in the inclined direction D13 by the guide section 12, to the front side of the inclined direction D13 by the rotation of the transport roller 131. The first frame section 14 is a metal frame on which the receiving section 11, the guide section 12, and the transport section 13 are mounted.

[0015] The swivel section 15 is a mechanism that swivels the first frame section 14, on which the above-mentioned parts are mounted, in a swivel direction D14 centered on a swivel axis 15a. The swivel axis 15a is an axis perpendicular to both the receiving direction D12 in the receiving section 11 and the inclination direction D13 in the guide section 12. The swivel section 15 then swivels the first frame section 14 between a first posture P11 in which the receiving section 11 can receive the twisted tube W12, and a second posture P12 in which the guide section 12 can be guided along the linearly arranged electric wire W11. In this embodiment, since the inclination angle of the guide section 12 is approximately 45°, the swivel angle between the first posture P11 and the second posture P12 is also approximately 45°. This swivel section 15 has a cylinder mechanism 151 that rotates the first frame section 14 around the swivel axis 15a by pushing and pulling a part of the first frame section 14, which is pivotally supported on the swivel axis 15a, in a straight line.

[0016] The second frame section 16 is a metal frame installed at a predetermined location, on which the first frame section 14 and the swivel section 15 are mounted. This second frame section 16 is composed of multiple rectangular columnar frame members 161 combined together. In this embodiment, the first frame section 14 and the swivel section 15 are attached to the connecting / separating movement section 17, which will be described later, and this connecting / separating movement section 17 is attached to the wire direction movement section 18, which will be described later. This wire direction movement section 18 is attached to one frame member 161 in the vertical direction D11 of the second frame section 16. In other words, in this embodiment, the first frame section 14 and the swivel section 15 are mounted on the second frame section 16 via the connecting / separating movement section 17 and the wire direction movement section 18, and the connecting / separating movement section 17 is mounted on the second frame section 16 via the wire direction movement section 18. The wire direction movement section 18 is directly mounted on the second frame section 16.

[0017] The contact / separation movement unit 17 is mounted on the second frame unit 16 via the wire direction movement unit 18 as described above, and is a mechanism that moves the first frame unit 14 in the following contact / separation direction D15. The contact / separation direction D15 is perpendicular to both the wire W11 and the pivot axis 15a, which are arranged linearly in the vertical direction D11. The contact / separation movement unit 17 slides the first frame unit 14 between a separation position P13 (Figure 3) and a contact position P14 (Figure 3) relative to the wire W11 in this contact / separation direction D15. The separation position P13 is the position of the first frame unit 14 where the guide unit 12 is separated from the wire W11 even when the second posture P12 is adopted. The contact position P14 is the position of the first frame unit 14 where the guide unit 12 contacts the wire W11 after the second posture P12 is adopted. This connecting / separating moving section 17 has a connecting / separating rail section 171 attached to the wire direction moving section 18, and a connecting / separating movable section 172 that is held by the connecting / separating rail section 171 in a state where it can slide in the connecting / separating direction D15. The first frame section 14 and the swivel section 15 are attached to the slidable connecting / separating movable section 172.

[0018] At this time, the attachment of the first frame section 14 to the connecting / separating movement section 17, that is, the attachment of the first frame section 14 to the second frame section 16, is such that it can be reversed and reattached as follows. First, the receiving section 11 mounted on the first frame section 14 receives the twisted tube W12 with the horizontal direction D12 being perpendicular to both the electric wire W11 and the pivot axis 15a which are arranged linearly in the vertical direction D11. The attachment of the first frame section 14 is such that it can be reversed 180° with respect to the second frame section 16, with respect to the reversal axis 14a which is aligned with the receiving direction D12. The receiving section 11 is held on the first frame section 14 so that it can receive the twisted tube W12 in the receiving direction D12 both before and after the reversal of the first frame section 14. Furthermore, the guide section 12 is held on the first frame section 14 so that it can be guided along the electric wire W11 by rotation by the swivel section 15 both before and after the inversion of the first frame section 14. In addition, the guide section 12 is held on the first frame section 14 so that it guides the twisted tube W12 to one end of the electric wire W11 before inversion and to the other end after inversion. Figures 1 and 2 show the first frame section 14 attached so that the guide section 12 guides the twisted tube W12 to the upper end of the electric wire W11 which is arranged linearly in the vertical direction D11. When this first frame section 14 is inverted 180° around the inversion axis 14a and reattached, the guide section 12 takes on a position to guide the twisted tube W12 to the lower end of the electric wire W11.

[0019] The wire-direction moving part 18 is directly mounted on the frame member 161 of the second frame part 16 as described above, and moves the first frame part 14 in the wire direction D16 via the approaching / separating moving part 17. The wire direction D16 is the direction (vertical direction D11 in this embodiment) along the wire W11 arranged linearly. The wire-direction moving part 18 has a wire-direction rail part 181 that extends in the wire direction D16 and is attached to the frame member 161, and a wire-direction movable part 182 that is slidably held by the wire-direction rail part 181. The approaching / separating moving part 17 is attached to the slidable wire-direction movable part 182.

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

[0021] FIG. 3 is a diagram showing the first half of a series of operations from when the twist tube is received by the receiving part until it is sent out to the wire in the exterior material mounting device shown in FIGS. 1 and 2. Further, FIG. 4 is a diagram showing the second half of the series of operations following the operation of FIG. 3 from when the twist tube is received by the receiving part until it is sent out to the wire in the exterior material mounting device shown in FIGS. 1 and 2.

[0022] First, in step S11 of FIG. 3, the twist tube W12 is received by the exterior material mounting device 1. In the receiving stage of this step S11, the approaching / separating moving part 17 positions the first frame part 14 in the approaching / separating direction D15 at the separation position P13 where the guide part 12 is separated from the wire W11. Further, the turning part 15 sets the first frame part 14 to the first posture P11 in which the receiving part 11 can receive the twist tube W12. The receiving part 11 facing horizontally in this first posture P11 receives the twist tube W12 in the horizontal receiving direction D12. Incidentally, at this stage, the guide part 12 is in a state inclined horizontally with respect to the wire W11.

[0023] When the twisted tube W12 is received by the exterior material mounting device 1, in the next step S12, the swivel section 15 swivels the first frame section 14 in the upward guide direction D141 of the swivel direction D14 around the swivel axis 15a to set it to the second posture P12. The upward guide direction D141 is the direction in which the guide section 12 is raised upward and aligned with the electric wire W11. In the swivel stage of step S12, the first frame section 14 is still positioned at the distance position P13, and the guide section 12 is in a position aligned with the electric wire W11, but away from the electric wire W11.

[0024] In step S13, following the rotation of the first frame section 14 by the swivel section 15, the contact / separation movement section 17 slides the first frame section 14, which has already rotated to the second posture P12, in the wire proximity direction D151 within the contact / separation direction D15. The wire proximity direction D151 is the direction that brings the guide section 12 closer to the electric wire W11. This sliding movement in the wire proximity direction D151 positions the first frame section 14 at a contact position P14 where the guide section 12 comes into contact with the electric wire W11. In this embodiment, the feeding destination of the twisted tube W12 is the position where the feeding end of the twisted tube W12 is tape-wrapped and fixed to the electric wire W11 by the tape-wrapping mechanism M1 described above. In the proximity stage of step S14, the guide section 12 is positioned below the tape-wrapping position P15 by the tape-wrapping mechanism M1.

[0025] In step S14, following the sliding movement of the first frame section 14 by the connecting / separating movement section 17, the tape M11 is wrapped around the tape winding position P15 on the electric wire W11 by the tape winding mechanism M1. In this electric wire tape winding stage of step S14, the tape M11 is wrapped around the tape winding position P15, which is located above the guide section 12.

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

[0027] In step S16, following the upward movement of the first frame section 14 by the wire direction movement section 18, the twisted tube W12 is fed out by the transport section 13. During the feeding stage of step S16, the twisted tube W12 received by the receiving section 11 is guided upward by the guide section 12 and fed out so that the electric wire W11 is contained inside. The feeding at this time is performed so that the fed end of the twisted tube W12 overlaps with the middle of the width direction of the tape M11 at the tape winding position P15. Then, in a stage not shown that follows step S16, the tape winding mechanism M1 winds the tape around the fed end of the twisted tube W12, and with the fed end fixed to the electric wire W11 by the tape, the twisted tube W12 is attached to the electric wire W11.

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

[0029] Figure 5 shows the reversal and reattachment of the first frame in the exterior material mounting device shown in Figures 1 to 4. Step S21 in Figure 5 shows that the first frame section 14, after being reversed and reattached, is set to the first posture P11 by the swivel section 15 and positioned at the separated position P13 by the contact / separation movement section 17. Then, step S22 in Figure 5 shows that this first frame section 14 is set to the second posture P12 by the swivel section 15. Note that in step S22, the first frame section 14 remains positioned at the separated position P13.

[0030] In this embodiment, the reversal is performed by the operator temporarily removing the first frame portion 14 of the exterior material mounting device 1 from the connecting / separating movement portion 17, reversing it 180° around the reversal axis 14a, and then reattaching it to the connecting / separating movement portion 17. This reversal causes the guide portion 12 to extend in the opposite direction to before the reversal. However, the receiving portion 11 will face the horizontal receiving direction D12 both before and after the reversal, and will be able to receive the twisted tube W12 in this horizontal receiving direction D12 without change before or after the reversal. On the other hand, since the guide portion 12 extends in the opposite direction to before the reversal, when the first frame portion 14 is rotated as in step S22, the guide portion 12 will be positioned along the electric wire W11 in a posture that guides the twisted tube W12 downwards in the opposite direction to before the reversal. Furthermore, in the first frame section 14, the point where the cylinder mechanism 151 of the pivot section 15 pushes and pulls is on the opposite side from the cylinder mechanism 151 compared to before the reversal, so the direction of rotation of the first frame section 14 by the pivot section 15 is also reversed compared to before the reversal. That is, the rotation after the reversal is a rotation in the downward guide direction D142, which is one of the rotation directions D14 around the pivot axis 15a, raising the guide section 12 downwards and aligning it with the electric wire W11. After this step S22, the same operations as steps S13 to S16 in Figures 3 and 4 are performed. Through these operations, the twisted tube W12 is fed towards the lower end, with the tape winding position P16 on the lower end side of the tape winding mechanism M1 located on the lower end side of the electric wire W11 as the destination, and the twisted tube W12 is attached to the electric wire W11.

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

[0032] In this embodiment, the electric wire W11 is arranged linearly in the vertical direction D11 along gravity, and the second posture P12 of the first frame portion 14 is such that the guide portion 12 extends in the vertical direction D11. With this configuration, the twisted tube W12 can be easily attached to the electric wire W11, which is arranged linearly in the vertical direction D11, resulting in a significantly smaller installation area along the horizontal plane compared to horizontal placement, etc.

[0033] Furthermore, in this embodiment, the swivel section 15 has a cylinder mechanism 151 that rotates the first frame section 14 by linearly pushing and pulling a part of the first frame section 14 which is pivotally supported on the swivel axis 15a. With this configuration, by using a cylinder mechanism 151 that is suitable for movement between two states, a first posture P11 and a second posture P12, the first frame section 14 can be rotated at a lower cost compared to, for example, the case where a servo motor is used.

[0034] Furthermore, in this embodiment, the first frame section 14 can be reattached by reversing it 180° around the reversal axis 14a. The receiving section 11 can receive the twisted tube W12 in the receiving direction D12 both before and after the reversal. The guide section 12 can be guided along the electric wire W11 by the rotation of the swivel section 15 both before and after the reversal. The guide section 12 is held by the first frame section 14 so as to guide the twisted tube W12 to one end of the electric wire W11 before the reversal and to the other end after the reversal. With this configuration, by reversing and reattaching the first frame section 14 to the second frame section 16, it is possible to guide the twisted tube W12 to either end of the electric wire W11. In addition, the receiving section 11 can receive the twisted tube W12 in a common receiving direction D12. By adopting this interchangeable configuration, it is not necessary to prepare two separate devices, one for one end of the electric wire W11 and the other for the other end, and manufacturing costs for attaching the twisted tube W12 can be significantly reduced.

[0035] Furthermore, in this embodiment, a contact / separation movement unit 17 is provided to move the first frame portion 14 in the direction of contact / separation D15 with respect to the electric wire W11. This contact / separation movement unit 17 moves the first frame portion 14 between a separation position P13 in the second posture P12 where the guide portion 12 is separated from the electric wire W11, and a contact position P14 in the second posture P12 where the guide portion 12 is in contact with the electric wire W11. With this configuration, by positioning the first frame portion 14 at the separation position P13, the rotation of the first frame portion 14 can be performed in a good state where the guide portion 12 is separated from the electric wire W11 and interference is suppressed.

[0036] Furthermore, in this embodiment, a wire direction movement unit 18 is provided to move the first frame unit 14 in the wire direction D16 along the linearly arranged electric wires W11. With this configuration, by moving the first frame unit 14 with the wire direction movement unit 18, the guide unit 12 can be positioned so that the twisted tube W12 can be fed towards any point in the wire direction D16.

[0037] It should be noted that the embodiments described above merely represent typical forms of exterior material mounting devices. Exterior material mounting devices are not limited to these and can be implemented in various modified forms.

[0038] For example, in the embodiment described above, an example of an exterior material mounting device is shown, which is an exterior material mounting device 1 that attaches a twisted tube W12 as an exterior material to an electric wire W11. However, the exterior material mounting device is not limited to this. As for the exterior material to be attached, any other exterior material such as a corrugated tube may be used, as long as it is tubular in shape and can be attached to the electric wire while housing the electric wire inside through slits provided in the peripheral wall.

[0039] Furthermore, in the above-described embodiment, an example of an exterior material mounting device is shown in which each component is attached to a second frame section 16 formed by combining multiple frame materials 161. However, the exterior material mounting device is not limited to this, and any specific frame configuration, such as the second frame, can be adopted.

[0040] Furthermore, in the above-described embodiment, an example of an exterior material attachment device is provided in which the destination of the twisted tube W12 as exterior material is the tape winding position P15 of the electric wire W11 by the tape winding mechanism M1. However, the exterior material attachment device is not limited to this, and the specific destination of the exterior material on the electric wire is not limited.

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

[0042] Furthermore, in the above-described embodiment, an example of an exterior material mounting device is shown in which the electric wires W11 are arranged linearly in the vertical direction D11, and the second posture P12 of the first frame portion 14 is such that the guide portion 12 extends in the vertical direction D11. However, the exterior material mounting device is not limited to this, and the electric wires may be arranged horizontally along the horizontal direction. In this case, the second posture of the first frame portion is such that the guide portion extends in the horizontal direction. However, as mentioned above, by arranging the electric wires W11 in the vertical direction D11 and extending the guide portion 12 of the second posture P12 in the vertical direction D11, the installation area of ​​the electric wires W11 can be significantly reduced, and the twisted tube W12 can be mounted well.

[0043] Furthermore, in the above-described embodiment, a swivel section 15 having a cylinder mechanism 151 for swiveling the first frame section 14 is exemplified as an example of a swivel section. However, the swivel section is not limited to this, and may, for example, use a servo motor to swivel the first frame. However, as mentioned above, using the cylinder mechanism 151 allows the first frame section 14 to be swiveled while keeping costs down.

[0044] Furthermore, in the above-described embodiment, an example of an exterior material mounting device is provided, which is an exterior material mounting device 1 in which the first frame portion 14 can be reversed and reattached. In this exterior material mounting device 1, both before and after reversal, it is possible to receive the wire in the receiving direction D12 of the receiving portion 11 and to guide the guide portion 12 along the electric wire W11 by rotation. The guide portion 12 guides the twisted tube W12 to one end of the electric wire W11 before reversal and to the other end after reversal. However, the exterior material mounting device is not limited to this, and it may be one in which the first frame portion cannot be reversed and reattached, and the receiving direction of the receiving portion and the direction of guidance by the guide portion are uniquely determined. Alternatively, it may be one in which the first frame portion can be reversed and reattached, and both the receiving direction of the receiving portion and the guidance direction of the guide portion change before and after reversal. However, as mentioned above, if the first frame section 14 can be reversed and replaced, and the receiving direction D12 remains unchanged before and after reversal, but the guiding direction changes to the opposite direction, then the manufacturing cost for attaching the twisted tube W12 can be significantly reduced.

[0045] Furthermore, in the above-described embodiment, an example of an exterior material mounting device is provided in which an exterior material mounting device 1 is provided with a contact-to-contact movement unit 17 that moves the first frame portion 14 between a separation position P13 and a contact position P14 with respect to the electric wire W11. However, the exterior material mounting device is not limited to this, and a configuration in which the guide portion does not particularly make contact with or move away from the electric wire is also possible. However, as mentioned above, by providing the contact-to-contact movement unit 17, the rotation of the first frame portion 14 can be performed in a good 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 example of an exterior material mounting device is provided in which an exterior material mounting device 1 is equipped with a wire-direction moving part 18 that moves the first frame part 14 in the wire direction D16 along the electric wire W11. However, the exterior material mounting device is not limited to this, and a configuration in which the first frame part does not move in the wire direction is also possible. However, as mentioned above, by providing the wire-direction moving part 18, the guide part 12 can be positioned so that the twist tube W12 can be fed towards any point in the wire direction D16.
