[0039] The following describes embodiments of a tape winding method and a wire harness.

[0040] Figure 1 It is a schematic diagram showing a wire harness according to an embodiment and a tape set for a tape winding task of the wire harness.

[0041] The wire harness 1 according to the present embodiment is, for example, installed and wired in a vehicle or the like. For purposes such as waterproofing, the wire harness 1 is provided with a tape wound around its outer periphery. The wire harness 1 includes a tape winding target 1a, a winding start portion 11, an overlap winding portion 12, and a winding end portion 13.

[0042] The tape winding target 1a is a wire portion having a bundle of one wire or a plurality of wires. The winding start portion 11 is a portion where the tape is wound around the winding start position of the tape winding target 1a using the winding method described below. The overlapping winding portion 12 is a tape winding portion after the winding start portion 11. The overlapping winding portion 12 is a portion where the following overlapping winding is continuously performed in the length direction D11 of the tape winding target 1a. The overlapping winding in the overlapping winding portion 12 is a winding method in which adjacent tapes 21 among a plurality of (two in this embodiment) tapes 21 having the same tape width T11 overlap each other with a required overlapping width R11 (1 / 3 of the tape width T11 in the present invention). The winding end portion 13 is a portion where the tape is wound around the winding end position of the tape winding target 1a using the same winding method as the winding start portion 11 after the overlapping winding portion 12.

[0043] In the tape winding of any one of the winding start portion 11, the overlapping winding portion 12, and the winding end portion 13, a tape group 2 is used. The tape group 2 includes two tapes 21 having the same tape width T11 arranged at a tape pitch W11 equal to the tape width T11 in the winding axis direction D12. The tape winding is performed by moving the tape group 2 in the moving direction D14 along the length direction D11 of the tape winding target 1a while rotating the tape group 2 around the tape winding target 1a in the rotation direction D13.

[0044] The tape winding method for forming such a wire harness 1 is described below.

[0045] Figure 2 is a schematic diagram showing the processing in the initial stage of the tape winding method for forming Figure 1 the wire harness shown. Figure 3 is a schematic diagram showing the processing after the initial stage in the tape winding method for forming Figure 1 the wire harness shown. Figure 2 after the initial stage. Figure 4 is to Figure 2 and Figure 3 a schematic diagram further abstracting the tape winding method shown.

[0046] In step S11 of these Figures 2 to 4 shown tape winding methods, without moving the tape group 2 in the moving direction D14, the non-moving tape winding is performed two or more times (twice in this embodiment) around the tape winding target 1a. As a result of the non-moving tape winding in step S11, the two tapes 21 are wound twice with a tape pitch W11 between the two tapes 21. In this embodiment, the tape pitch W11 is the same as the tape width T11, and in the following description, this distance is referred to as the reference distance d.

[0047] In subsequent steps S12 and S13, the first overlapping step is performed as follows. This first overlapping step is a step for performing a first overlapping winding, in which each of the two belts 21 of the belt group 2 partially overlaps with the belt 21 itself. In the present embodiment, each belt 21 overlaps with the belt 21 itself by more than 1 / 3 of the overlapping width (specifically, as described below, 1 / 2 of the width). This first overlapping winding is performed until the front edge 211 of the rear belt 21a among the two belts 21 coincides with the rear edge 212 of the front belt 21b. The rear belt 21a is the belt 21 wound on the rearmost side in the moving direction D14, and the front belt 21b is the belt 21 wound adjacent to the rear belt 21 on the front side in the moving direction D114. The front edge 211 is the front edge in the moving direction D14 of the belt 21 wound on the belt winding target 1a, and the rear edge 212 is the rear edge in the moving direction D14 of the wound belt 21.

[0048] In the present embodiment, the belt pitch W11 is a reference distance d, which is equal to the belt width T11. The first overlapping step is a step for performing a half-overlapping winding as the first overlapping winding twice, in which each of the two belts 21 partially overlaps with the belt 21 itself by 1 / 2 of the width, that is, half of the reference distance d, until the following overlapping state is obtained. That is, the half-overlapping winding as the first overlapping winding is performed twice until the front edge 211 of the rear belt 21a coincides with the rear edge 212 of the front belt 21b. In steps S12 and S13, the belt group 2 moves 1 / 2 of the width in the moving direction D14.

[0049] In step S14 after the above first overlapping step, the second overlapping step is performed as described below. The second overlapping step is a step for performing a second overlapping winding once, in which while the belt group 2 moves in the moving direction D14, each of the two belts 21 partially overlaps with the belt 21 itself and the rear belt 21a partially overlaps with the front belt 21b. In the present embodiment, the second overlapping winding is such a belt winding that each belt 21 overlaps with the belt 21 itself by more than 1 / 3 of the overlapping width, specifically, 1 / 3 of the width, that is, 1 / 3 of the reference distance d, and the rear belt 21a overlaps with the front belt 21b by more than 1 / 3 of the overlapping width, specifically, 1 / 3 of the width. As a result of the second overlapping step in step S14, the boundary between the rear belt 21a and the front belt 21b formed in the stage of step S13 is covered by the rear belt 21a wound thereon. In the second overlapping step of step S14, the belt group 2 moves 2 / 3 of the width, that is, 2 / 3 of the reference distance d, in the moving direction D14.

[0050] The processing in the above steps S11 to S14 is a winding start step for forming by performing belt winding on the winding start portion of the belt winding target 1aFigure 1 The winding start portion 11 shown.

[0051] In the next step S15, an overlapping winding is performed in which two adjacent tapes 21 in the tape group 2 partially overlap in the moving direction D14. In the present embodiment, the overlapping winding in this case is a tape winding in which the rear tape 21a overlaps more than 1 / 3 of the overlapping width with the front tape 21b, specifically, 1 / 3 of the overlapping width, that is, 1 / 3 of the reference distance d. At this time, the rear tape 21a is spaced 1 / 3 of the width from the previously wound rear tape 21a located behind in the moving direction D14, but the previously wound front tape 21b exists in this spaced portion. The presence of the previously wound front tape 21b ensures the overlap of the spaced portion of the rear tape 21a. In this step S15, the tape group 2 is moved in the moving direction D14 by the moving amount of each overlapping winding, that is, the tape pitch W11 equal to the reference distance d plus the overlapping width R11 which is 1 / 3 of the reference distance d. That is, the moving amount is 4 / 3 of the reference distance d. This moving amount is the winding length in the length direction D11 of each winding of the overlapping winding of each tape 21.

[0052] In the next step S16, an overlapping winding is performed in a similar manner to step S15. In this overlapping winding in step S16, the front side of the rear tape 21a overlaps 1 / 3 of the overlapping width with the front tape 21b, and the rear side of the rear tape 21a overlaps 1 / 3 of the repeating width with the previously wound front tape 21b. In this way, an overlapping width R11 of 1 / 3 of the width is ensured on both the front and rear sides of the front tape 21b. Thereafter, while the tape group 2 is moved by the above-mentioned moving amount (4 / 3 of the reference distance d) for each overlapping winding, the overlapping winding similar to step S16 is continuously continued until the winding end portion of the tape winding target 1a. The overlapping winding performed from step S15 with the above-mentioned moving amount is an overlapping winding step for performing the following overlapping winding: while the tape group 2 is moved by the above-mentioned moving amount for each overlapping winding, adjacent tapes 21 overlap more than 1 / 3 of the overlapping width with each other. As a result of this overlapping winding step, Figure 1 The overlapping winding portion 12 shown is formed.

[0053] When the tape group 2 reaches the winding end portion, the overlapping winding step ends, and a winding end step is performed. In this winding end step, the tape is wound using the same winding method as in the winding start steps of steps S11 to S14. However, in this winding end step, first, a first overlapping step for performing two semi-overlapping windings in steps S12 and S13 and a second overlapping step in step S14 are performed. After the second overlapping step, two stationary tape windings in step S11 are performed. This winding end step forms Figure 1 The winding end portion 13 shown, and the tape winding method for winding the tape on the wire harness 1 is completed.

[0054] According to the tape winding method of the above embodiment, in the area where overlapping winding is required, the overlapping winding in which a part (more than 1 / 3 of the width in this embodiment) of adjacent tapes 21 overlaps is performed by moving the tape group 2 as follows. Specifically, while moving the tape group 2 by the sum of the tape pitch W11 and the overlapping width R11 (the moving amount for each overlapping winding), the overlapping winding is performed. This movement ensures the required overlapping width R11, but compared with the overlapping winding in which the tape movement amount for each winding is limited to the overlapping width R11, this movement improves the efficiency of the tape winding task.

[0055] For example, when using a single tape with a width of 19 mm for semi-overlapping winding, the movement amount of the tape for each winding is 9.5 mm. Even if the overlapping width R11 is set to 1 / 3 of the width, due to the limitation of the overlapping width R11, the maximum movement amount of the tape for each winding can only reach 12.6 mm.

[0056] In contrast, according to the tape winding method of this embodiment, for the tape 21 with a width of 19 mm, the movement amount for each overlapping winding (4 / 3 of the reference distance d equal to the tape width T11) is 25.3 mm, which can increase the efficiency of the task to 183%. For the tape 21 with a width of 25 mm, the movement amount becomes 33.3 mm, which can increase the efficiency of the task to 244%.

[0057] In this embodiment, both the winding start step and the winding end step are steps including the first overlapping step in steps S12 and S13 and the second overlapping step in step S14. The first overlapping step is a step for performing the first overlapping winding. In this first overlapping step, each tape 21 overlaps with itself partially (more than 1 / 3 of the width in this embodiment) until the front edge 211 of the rear tape 21a coincides with the rear edge 212 of the front tape 21b. The second overlapping step is a step for performing the second overlapping winding once. In this second overlapping step, each tape 21 overlaps with itself partially (more than 1 / 3 of the width in this embodiment), and the rear tape 21a overlaps with the front tape 21b (more than 1 / 3 of the width in this embodiment). According to this configuration, not only in the overlapping winding step, but also in the winding start step, the transition from the winding start step to the overlapping winding step, the transition from the overlapping winding step to the winding end step, and the winding end step, an overlapping width R11 of more than 1 / 3 of the width can be ensured.

[0058] In addition, in the present embodiment, the two belts 21 have the same belt width T11, the belt pitch W11 is the reference distance d that is the same as the belt width T11, and the first overlapping step is a step for performing two semi-overlapping windings. According to this configuration, for the first overlapping step in which the movement amount of the belt group 2 is limited to 1 / 2 of the width of the belt, the number of times of performing the semi-overlapping winding is limited to two, which is the required minimum number of times. Therefore, including the winding start step and the winding end step, this further improves the efficiency of the belt winding task.

[0059] In addition, in the present embodiment, the winding start step is a step of performing more than two non-moving belt windings before the first overlapping step, and the winding end step is a step of performing more than two non-moving belt windings after the second overlapping step. According to this configuration, non-moving belt windings are performed both in the initial step of the winding start step and the last step of the winding end step, which can stabilize the winding state at the start and end of winding.

[0060] In addition, the wire harness 1 according to the present embodiment is formed by performing belt winding on the belt winding target 1a by the above-described belt winding method. Specifically, in the manufacture of the wire harness 1, the above-described belt winding method is adopted, and while maintaining the required overlapping width R11 of more than 1 / 3 of the width, the efficiency of the belt winding task is improved.

[0061] Next, a modification example of the above embodiment will be described.

[0062] Figure 5 is shown Figures 1 to 4 a schematic diagram showing a modification example of the illustrated embodiment.

[0063] Figure 5 The difference between the illustrated modification example and the above embodiment lies in: the winding method of the belt 21 on the overlapping winding portion 32 of the wire harness 3; and the orientation of the belt group 2 with respect to the belt winding target 1a during the overlapping winding step of forming the overlapping winding portion 32. The following describes this modification example, focusing on the differences from the above embodiment. Figure 5 Only the part corresponding to the overlapping winding portion 12 shown and the belt group 2 of the overlapping winding portion 32 of the wire harness 3 according to the modification example are shown. In Figure 1 the components equivalent to those in the illustrated embodiment are only identified with the same reference numerals as in Figure 5 when necessary. In the following, the repeated description of these equivalent components is omitted. Figure 1 the illustrated embodiment are only identified with the same reference numerals as in Figure 1 when necessary. In the following, the repeated description of these equivalent components is omitted.

[0064] In the above-described embodiment, during the overlapping winding, the tape group 2 is arranged such that the orientation of each tape 21 is substantially perpendicular to the length direction D11 of the tape winding target 1a. In contrast, in the present modification example, the overlapping winding is performed by tilting the tape group 2 so that the tapes 21 of the tape group 2 are wound at a predetermined angle with respect to the length direction D11 of the tape winding target 1a. The overlapping winding is performed by rotating the tilted tape group 2 around the tape winding target 1a in the rotation direction D13 and moving the tape group 2 in the moving direction D14 along the length direction D11 of the tape winding target 1a. The overlapping winding portion 32 formed by this type of overlapping winding is formed such that each adjacent tape 21 wound at a predetermined angle partially overlaps with each other. At this time, the overlapping width R31 in the length direction D11 of the overlapping portion tilted according to the tilt of the tape 21 is 1 / 3 of the width of the tape width T11.

[0065] In the present modification example, the overlapping winding portion 32 is formed by the overlapping winding step of the above-described tilted winding. Although not further explained, the winding start step and the winding end step before and after the overlapping winding step are performed in the same manner as in the above-described embodiment with the tape group 2 positioned such that the tapes 21 are substantially perpendicular to the length direction D11. However, for the winding start step and the winding end step, the above-described tilted winding may also be partially used. That is, the overlapping winding after the non-moving tape winding in the winding start step and the overlapping winding before the non-moving tape winding in the winding end step may also be performed using the above-described tilted winding.

[0066] According to the above modification example, it should be understood that, as in the above-described embodiment, it is possible to improve the efficiency of the tape winding task while ensuring the required overlapping width R31 (in this modified embodiment, more than 1 / 3 of the width, specifically 1 / 3 of the width).

[0067] In addition, in the present modification example, in the winding start step, the overlapping winding step, and the winding end step, at least the overlapping winding step (in this modified embodiment, only the overlapping winding step) is performed by winding the tape group 2 at a certain angle. According to this configuration, the tapes 21 of the tape group 2 are wound obliquely so that the tape winding range of each winding is wider than when the tapes 21 are wound substantially perpendicular to the length direction D11. The increase in the tape winding range of each tape winding can further improve the efficiency of the tape winding task.

[0068] The above-described embodiments and modification examples are merely representative forms of the tape winding method and the wire harness. The tape winding method and the wire harness are not limited thereto, and can be implemented in various modifications.

[0069] For example, in the above-described embodiments and modified examples, as an example of the wire harness, the wire harness 1 installed on a vehicle or the like and wired in the vehicle or the like is shown. However, the wire harness is not limited thereto, and its specific application is not particularly limited either.

[0070] In addition, in the above-described embodiments and modified examples, as an example of the tape group for the tape winding method, the tape group 2 including two tapes 21 arranged in the winding axis direction D12 is shown. However, the tape group is not limited thereto, and any number of tapes can be used as long as it is more than one.

[0071] In addition, in the above-described embodiments and modified examples, as an example of the overlapping winding steps, the following steps are shown. That is, the overlapping winding steps S15 and S16 are shown, in which adjacent tapes 21 overlap each other by more than 1 / 3 of the width, specifically, 1 / 3 of the overlapping width (1 / 3 of the reference distance d). However, the overlapping width in the overlapping winding steps can be any other overlapping width as long as it is an overlapping width that allows partial overlap.

[0072] In addition, in the above-described embodiments and modified examples, as an example of each of the winding start step and the winding end step, the steps including the first overlapping step in steps S12 and S13 and the second overlapping step in step S14 are shown. However, the winding start step and the winding end step are not limited thereto, and their specific winding methods are not particularly limited either. However, as described above, when the above first overlapping step and the second overlapping step of step S14 are performed, the desired overlapping widths R11 and R31 (in this case, more than 1 / 3 of the width) for each step from the winding start step to the winding end step can be ensured.

[0073] In addition, in the above-described embodiments and modified examples, as an example of the first overlapping step, the following steps are shown. That is, the above-described embodiments and modified examples show the first overlapping step in steps S12 and S13, in which, when the two tapes 21 in the tape group 2 have the same tape width T11 and the tape pitch W11 is equal to the tape width T11, two half-overlapping windings are performed. However, the first overlapping step is not limited thereto, and the tape widths of multiple tapes in the tape group can be different from each other, and the tape pitch of the tape group, the overlapping width corresponding to the tape pitch, and the number of tape windings can be set to any values. However, as described above, when the tape pitch W11 of the two tapes 21 having the same width is set to be equal to the tape width T11 and the half-overlapping winding is configured to be performed twice, the efficiency of the tape winding task can be further improved including the winding start step and the winding end step.

[0074] In addition, in the above-described embodiments and modified examples, as an example of each of the winding start step and the winding end step, a step of performing non-moving tape winding two or more times is shown. However, the winding start step and the winding end step are not limited thereto, and may be steps in which non-moving tape winding is not particularly performed. However, as described above, when non-moving tape winding is performed two or more times, the winding states at the start and end of winding can be stabilized. In the present embodiment, a step of performing non-moving tape winding twice in the winding start step and the winding end step is illustrated, but the number of times of performing non-moving tape winding is not limited to two, and the specific number is not particularly limited as long as it is two or more times.

[0075] In addition, in the above-described modified example, as an example of the tape winding method, a tape winding method is shown in which, in the winding start step, the overlapping winding step, and the winding end step, the overlapping winding step is performed by inclined winding. However, the tape winding method is not limited thereto, and as in the above-described embodiment, in each step, tape winding may be performed in a case where the tape group 2 is arranged such that the orientation of each tape 21 is substantially perpendicular to the length direction D11 of the tape winding target 1a. Further, even when inclined winding is used, as described above, the step to which inclined winding is applied is not limited to the overlapping winding step, and inclined winding can be used for the winding start step or the winding end step.
