Description

Technical Field

[0001] The present invention relates to a wire harness and a wire harness bundling method. The wire harness is a wire harness obtained by bundling a bundled body with a bundling body, the bundling body being formed of a flexible wire material, and the bundled body including a plurality of electric wires. Background Art

[0002] Conventionally, a wiring harness formed by bundling a plurality of electric wires, optical fibers, etc. (electrical wires) for power supply and signal communication is used in automobiles and various mechanical devices. The process of manufacturing the wiring harness includes bundling a plurality of electric wires using a bundling member such as an adhesive tape.

[0003] If workers manually perform the work of bundling wires using a bundling body, it takes a lot of time. In addition, due to the different proficiency of workers, there is a risk that the quality of the wire harness will be unstable. Therefore, a wire harness manufacturing device is proposed that automates the work of bundling wires using a bundling body.

[0004] For example, the wire harness manufacturing device disclosed in Patent Document 1 performs an operation in which a tape winding device freely moves in three-dimensional directions with respect to a bundle of a plurality of electric wires arranged in a bundle wiring device, and winds a tape around the electric wires.

[0005] According to the wire harness manufacturing device of Patent Document 1, the operation of bundling electric wires with adhesive tape can be automated. However, in the wire harness manufacturing device of Patent Document 1, the adhesive tape is wound around each location and the adhesive tape is cut after each location is wound. Therefore, in the wire harness manufacturing device of Patent Document 1, the adhesive tape cannot be continuously wound around the electric wires, and there is a problem that the operation of bundling a plurality of electric wires with a bundling body takes time.

[0006] On the other hand, a wire harness manufacturing device has been proposed that speeds up the operation of bundling a plurality of electric wires by using a bundling body other than an adhesive tape. For example, the wire harness manufacturing device disclosed in Patent Document 2 uses a linear object such as a yarn or a rope as a bundling body. In the wire harness manufacturing device, a bundle of electric wires moves in a longitudinal direction, and a winding wire feeder that supplies the linear object rotates around the electric wires, so that the linear object is spirally wound around the bundle of electric wires.

[0007] According to the wire harness manufacturing device of Patent Document 2, since a continuous linear object such as a yarn or a rope is spirally wound around the electric wires to bundle the electric wires, the operation of bundling the electric wires using the bundling body can be accelerated.

[0011] Patent Document 2: Japanese Utility Model Publication No. 6-5031 Summary of the invention

[0012] Problems to be solved by the invention

[0013] However, in the wire harness manufacturing device of Patent Document 2, the linear object spirally wound around the electric wires is not fixed to the electric wires like a tape, and there is no fixing portion such as a knot to maintain the spiral shape. Therefore, the position of the linear object may be offset relative to the electric wires and the spiral shape may not be maintained, and there is a risk that the bundling force of the electric wires will be reduced.

[0014] An object of the present invention is to provide a wire harness and a wire harness bundling method, which can automate and speed up the work of bundling wires with a bundling body by continuously bundling a plurality of wires, and can suppress a reduction in the bundling force of the wires.

[0015] Solutions for solving problems

[0016] The wire harness of the present invention is a wire harness obtained by bundling a bundled body with a bundling body, wherein the bundling body is formed of a flexible wire material, and the bundled body includes a plurality of electric wires, wherein the bundling body has a plurality of continuously formed annular portions, the plurality of annular portions are arranged along the length direction of the bundled body, and adjacent annular portions are connected to each other, so that the bundled body is bundled.

[0017] The wire harness bundling method of the present invention forms a wire harness by bundling a bundled body with a bundling body, wherein the bundling body is formed of a flexible wire material, and the bundled body includes a plurality of wires. The wire harness bundling method includes: a connecting step of forming a plurality of ring-shaped portions along the length direction of the bundled body and connecting the plurality of ring-shaped portions to each other.

[0018] Effects of the Invention

[0019] According to the wire harness and the wire harness bundling method of the present invention, by continuously bundling a plurality of electric wires with the bundling body, the work of bundling the electric wires with the bundling body can be automated and accelerated, and a reduction in the bundling force of the bundled electric wires can be suppressed.

[0048] [Wire Harness]

[0049] First, the wire harness will be described. Figure 1 1 is a diagram showing a part of a wire harness 100 according to Embodiment 1 of the present invention. The wire harness 100 is a wire harness in which a bundled object W is bundled with a bundled object 10 formed of a flexible wire material S, and the bundled object W includes a plurality of electric wires.

[0050] Figure 1 FIG. 1 shows the circumference of the wiring harness 100 when viewed from different directions with angles of 90 degrees. Figure 1 The surface shown in (a) is set as the upper surface of the wire harness 100, then Figure 1 (b) represents the side surface of the wire harness 100, Figure 1 (c) represents the bottom surface of the wire harness 100, and Figure 1 (d) indicates Figure 1 (b) is a side surface of the wire harness 100 on the opposite side. Figure 1 In (a) to (d), the longitudinal direction of the wire harness 100 is set as the Y-axis direction and the Z-axis direction is shown.

[0051] The wires include wires and optical fibers used for power supply and signal communication, and different types of wires may be mixed. The types of wires included in the bundled body W are not limited. Figure 1 In FIG. 1 , a bundled body W including a plurality of electric wires is simply shown in a cylindrical shape.

[0052] Fig.11 is a schematic diagram of the cross section of the bundled body W. Fig.11 As shown, the bundled body W includes a plurality of long bundled wires W10. The collection of the plurality of bundled wires W10 constitutes the long bundled body W. The bundled wires W10 are the above-mentioned electric wires. As described above, the bundled wires W10 include electric wires, optical fibers, etc. In the first embodiment, the peripheral surface of each of the plurality of bundled wires W10 is covered with a resin material. That is, each bundled wire W10 has: a core wire W1 formed of metal or glass arranged on the inside; and a covering portion W2 formed of a resin material covering the core wire W1. Therefore, the entire peripheral surface of the bundled body W is covered with a resin material.

[0053] The wire S can be any wire that has the flexibility to bend and the strength (tensile strength) to bind the bundled body W. Examples include yarn-shaped wires, rope-shaped wires, belt-shaped wires, metal wires, etc., but are not limited to these. In addition, the material is not limited, and examples thereof include natural fibers such as cotton and linen; chemical fibers such as nylon; and metals such as copper, aluminum, and stainless steel. In addition, blended fibers, yarns, filaments, etc. may be used, and wires obtained by twisting or braiding a plurality of strands may also be used.

[0054] like Figure 1 As shown in FIG. 1 , the bundled body 10 includes a plurality of annular portions 20. In the first embodiment, the annular portion 20 includes a first annular portion 21 and a second annular portion 22. The first annular portion 21 is formed from Figure 1 (a) is configured so that the lower right part shown in FIG. 1 extends to the upper left part, and the annular part 20 has a curved part in the upper left part of the annular part. In addition, the second annular part 22 is arranged from the Figure 1 The upper right portion shown in (a) is arranged to extend to the lower left portion, and is an annular portion 20 having a curved portion at the lower left portion of the annular portion.

[0055] The first annular portion 21 and the second annular portion 22 are formed repeatedly and continuously by respectively bending a portion of the wire S. Figure 1 As shown in (a) and (b), a plurality of annular portions 20 (a first annular portion 21 and a second annular portion 22) are arranged on the circumferential surface of the bundled body W along the longitudinal direction of the bundled body W. In the following description, the first annular portion 21 and the second annular portion 22 may be described as the annular portion 20 without distinguishing between them.

[0056] use Fig.12 The detailed structure of each element such as the annular portion 20 of the bundling body 10 will be described below. Fig.12 Is magnification Figure 1 Hereinafter, the circumferential direction of the bundled body W will be simply referred to as the circumferential direction as appropriate.

[0057] The bundled body W has a first peripheral surface W_A which is one of the two peripheral surfaces divided into two equal parts along the circumferential direction, and a second peripheral surface W_B which is the opposite side of the first peripheral surface W_A, and each annular portion 20 is arranged on the first peripheral surface W_A. Fig.11 As shown, when the bundled body W is divided by a line L0, the peripheral surface of the bundled body W on one side relative to the line L0 is the first peripheral surface W_A, and the peripheral surface on the other side is the second peripheral surface W_B, wherein the line L0 passes through the center of the bundled body W when viewed along the length direction of the bundled body W. The first annular portion 21 and the second annular portion 22 are arranged on the first peripheral surface W_A. In other words, the bundled body W has the first peripheral surface W_A on which the first annular portion 21 is arranged and the second peripheral surface W_B on the opposite side. In addition, Fig.12 This is a diagram of the bundled body W as viewed from the first peripheral surface W_A side.

[0058] The first annular portion 21 is formed in a substantially annular shape extending along the longitudinal direction of the bundled body W on the first circumferential surface W_A. The first annular portion 21 includes a first portion 21A extending from a base end portion 23 on one side of the left-right direction to a distal end portion 24 on the other side of the left-right direction, and a second portion 21B returning from the distal end portion 24 to the base end portion 23. The base end portion 23 of the first annular portion 21 includes an end portion 23A on one side of the left-right direction of the first portion 21A and an end portion 23B on one side of the left-right direction of the second portion 21B.

[0059] Similar to the first annular portion 21, the second annular portion 22 is formed in a substantially annular shape extending in the left-right direction, i.e., the longitudinal direction of the bundled body W, on the first circumferential surface W_A. The second annular portion 22 includes a third portion 22A extending from a base end portion 25, which is an end on one side in the left-right direction, to a distal end portion 26, which is an end on the other side, and a fourth portion 22B returning from the distal end portion 26 to the base end portion 25. The base end portion 25 of the second annular portion 22 includes an end portion 25A, which is one side in the left-right direction, of the third portion 22A and an end portion 25B, which is one side in the left-right direction of the fourth portion 22B.

[0060] Hereinafter, the longitudinal direction of the bundled body W is appropriately referred to as the left-right direction, and Fig.12 The right side, i.e., one side of the first annular portion 21 and the second annular portion 22 in the above description, that is, the base end portions 23, 25 sides of the annular portions 21, 22 relative to the distal end portions 24, 26 are set as the right, and the opposite side is set as the left for description.

[0061] That is, in the first embodiment, the right end of the first annular portion 21 is the base end 23 of the first annular portion 21, the left end is the distal end 24 of the first annular portion 21, the right end of the second annular portion 22 is the base end 25 of the second annular portion 22, and the left end is the distal end 26 of the second annular portion 22. Figure 1 and Fig.12 In the example of FIG. 1 , the first annular portion 21, the first portion 21A, and the second portion 21B extend from the base end portion 23 of the first annular portion 21 to the upper left, and the second annular portion 22, the third portion 22A, and the fourth portion 22B extend from the base end portion 25 of the second annular portion 22 to the lower left. In addition, the wire S constituting the right end portion of the first annular portion 21 is wired in a bent manner, and the wire S constituting the right end portion of the second annular portion 22 is wired in a bent manner.

[0062] Since the first annular portion 21 and the second annular portion 22 are formed of the flexible wire S, the shapes of the first annular portion 21 and the second annular portion 22 vary depending on the material of the wire S and the tension applied to the wire S, and are not limited to Figure 1 The first annular portion 21 and the second annular portion 22 may have the same size (length) or different sizes (lengths). The ratio of the size (length) of the first annular portion 21 and the second annular portion 22 to the thickness (diameter) of the bundled body W is also not limited.

[0063] Adjacent annular portions 20 (first annular portion 21, second annular portion 22) are connected to each other. Specifically, the second annular portion 22 is passed through the adjacent first annular portion 21, and another first annular portion 21 adjacent to the second annular portion 22 is passed through the second annular portion, and this operation is repeated, and the adjacent annular portions 20 (first annular portion 21, second annular portion 22) are continuously connected.

[0064] In the first embodiment, the first annular portion 21 and the second annular portion 22 are "connected" to each other, which refers to the following state: one of the first annular portion 21 and the second annular portion 22 passes through the other, and in this state, tension is applied to the wire S, so that the shapes and positional relationship of the first annular portion 21 and the second annular portion 22 that pass through each other are kept approximately constant.

[0065] Specifically, if Fig.12 As shown, the base end portion 25 of the second annular portion 221 (22) is wound around the distal end portion 24 of the first annular portion 211 (21) adjacent to the second annular portion 221 (22) on the right side, and the base end portion 25 of the second annular portion 221 (22) is hooked by the distal end portion 24 of the first annular portion 211 (21), so that they are connected. In addition, the distal end portion 26 of the second annular portion 221 (22) is wound around the base end portion 23 of the first annular portion 212 (21) adjacent to the second annular portion 221 (22) on the left side, and the base end portion 23 of the first annular portion 212 (21) is hooked by the distal end portion 26 of the second annular portion 221 (22), so that they are connected. As a result, the base end portion of each annular portion 20 is connected to the distal end portion of another adjacent annular portion 20, and the plurality of annular portions 20 are respectively connected to another adjacent annular portion 20.

[0066] The wire S forms the first constraining portion 31 between the connected first annular portion 21 and the second annular portion 22. Furthermore, the wire S forms the second constraining portion 32 between the connected second annular portion 22 and the first annular portion 21.

[0067] Specifically, if Figure 1 As shown in (a) and (b), the first constraint portion 31 is a portion where the wire S extends from the first annular portion 21 (211) to the second annular portion 22 (221) in the portion where the second annular portion 22 (221) passes through the first annular portion 21 (211). In addition, the second constraint portion 32 is a portion where the wire S extends from the second annular portion 22 (221) to the first annular portion 21 (212) in the portion where the first annular portion 21 (212) passes through the second annular portion 22 (221).

[0068] Fig.13 The dotted lines indicate the areas in the bundle 10 that are arranged Fig.12 The back side of the paper, that is, the portion on the second peripheral surface W_B, is shown with a dotted line. Fig.12 The first constraint part 31 and the second constraint part 32 are added. Figure 1 (a), (b) and Fig.13 As shown, the first constraint portion 31 extends from the base end portion 23 of the first annular portion 21 around the second circumferential surface W_B to the distal end portion 24 of the first annular portion 21. In addition, the second constraint portion 32 extends from the base end portion 25 of the second annular portion 22 around the second circumferential surface W_B to the distal end portion 26 of the second annular portion 22.

[0069] The first annular portion 21 and the first restraining portion 31 extending from the base end portion 23 of the first annular portion 21 to the distal end portion 24 are arranged so as to go around the circumference of the body to be bundled W. That is, the entire circumference of the body to be bundled W is surrounded by the first annular portion 21 and the first restraining portion 31 extending from the base end portion 23 of the first annular portion 21 to the distal end portion 24. Similarly, the second annular portion 22 and the second restraining portion 32 extending from the base end portion 25 of the second annular portion 22 to the distal end portion 26 are arranged so as to go around the circumference of the body to be bundled W, and the entire circumference of the body to be bundled W is surrounded by the second annular portion 22 and the second restraining portion 32 extending from the base end portion 25 of the second annular portion 22 to the distal end portion 26.

[0070] In the first embodiment, the lengths of the first constraint portion 31 and the second constraint portion 32 in the circumferential direction are both set to be longer than the lengths of the first annular portion 21 and the second annular portion 22 in the circumferential direction. In addition, the lengths of the first constraint portion 31 and the second constraint portion 32 in the circumferential direction are set to be substantially the same as each other. In addition, the lengths of the first annular portion 21 and the second annular portion 22 in the circumferential direction are set to be substantially the same as each other.

[0071] In the first embodiment, a continuous single wire S is chain-woven so as to surround the bundled body W, thereby forming the bundled body 10. Accordingly, the first portion 21A, the second portion 21B, the third portion 22A, the fourth portion 22B, the first restraining portion 31, and the second restraining portion 32 are formed by the continuous single wire S.

[0072] Here, chain weaving refers to a method of weaving the wires so that loops (meshes) formed by the wires are sequentially connected. In the first embodiment, the wires S are woven so that all loops formed by chain weaving surround the bundled body W, thereby forming the bundled body 10. In addition, the specific procedure for forming the bundled body 10 will be described later.

[0073] Accordingly, the first constraint portion 31 is directly connected to the third portion 22A at the base end portion 25 of the second annular portion 22. That is, the first constraint portion 31 extends from the right end portion 25A of the third portion 22A constituting the base end portion 25 of the second annular portion 22. In addition, the second constraint portion 32 is directly connected to the fourth portion 22B at the base end portion 25 of the second annular portion 22, and extends from the right end portion 25B of the fourth portion 22B constituting the base end portion 25 of the second annular portion 22.

[0074] Furthermore, the first restraining portion 31 is directly connected to the second portion 21B at the base end portion 23 of the first annular portion 21, and extends from the right end portion 23B of the second portion 21B constituting the base end portion 23 of the first annular portion 21. Furthermore, the second restraining portion 32 is directly connected to the first portion 21A at the base end portion 23 of the first annular portion 21, and extends from the end portion 23A of the first portion 21A constituting the base end portion 23 of the first annular portion 21.

[0075] As described above, the adjacent annular portions 20 (the first annular portion 21 and the second annular portion 22) are connected to each other to form the first restraining portion 31 and the second restraining portion 32 so as to surround the circumference of the bundled body W. The first restraining portion 31 and the second restraining portion 32 tighten the bundled body W by the tension applied to the wire S, so that the bundled body W is bundled by the bundled body 10.

[0076] Furthermore, since the adjacent annular portions 20 (the first annular portion 21 and the second annular portion 22) are connected to each other, the wires S are less likely to move due to friction between the wires S, and the tension applied to the wires S is less likely to decrease, thereby suppressing a decrease in the bundling force for bundling the objects W.

[0077] Furthermore, in the wire harness 100 according to the first embodiment, the first restraint portion 31 is directly connected to the third portion 22A at the base end portion 25 of the second annular portion 22. Therefore, according to the wire harness 100 according to the first embodiment, the wiring structure of the wire S at the base end portion 25 of the second annular portion 22 can be simplified. Furthermore, the labor and time for wiring the wire S can be reduced, and the labor and time for bundling the bundled body W using the wire S can be reduced. Similarly, according to the wire harness 100 according to the first embodiment, the wiring structure of the wire S can be simplified by directly connecting the second restraint portion 32 to the first portion 21A at the base end portion 23 of the first annular portion 21, and the labor and time for bundling the bundled body W using the wire S can be reduced.

[0078] Here, each annular portion 20 is arranged at approximately equal intervals in the left-right direction. The distance between the base end portions 23 of two adjacent first annular portions 21 in the left-right direction, that is, the size of the spacing P, is not limited. In addition, the size of the bundled body W is not limited. However, the inventors of the present application have found that if the diameter D of the bundled body W is set to be greater than 8 mm and less than 20 mm and the spacing P of the annular portions 20 is set to be greater than 0 mm and less than 18 mm, the robustness of the wire harness to temperature changes can be improved. Specifically, if Fig.11 The toughness of the wire harness is improved by setting the diameter D of the virtual circle R10 indicated by a dashed line, that is, the virtual circle R10 passing through the point WP on the peripheral surface of the bundled body W and surrounding the entire bundled body W when viewed in the left-right direction, to 8 mm or more and 20 mm or less, and setting the pitch P of the annular portion 20 to be greater than 0 mm and less than 18 mm.

[0079] Fig.14 It is a graph showing the relationship between the diameter D of the bundled body W (virtual circle R10) and the temperature displacement ratio. Fig.14 The line L1 in FIG. 1 shows the above relationship when the pitch P of the annular portion 20 is 2.0 mm, and the line L2 shows the above relationship when the pitch P of the annular portion 20 is 10 mm.

[0080] Fig.14 The temperature displacement ratio on the vertical axis is the ratio of the temperature displacement of the wire harness 100 formed by bundling the bundled body W using the above-mentioned bundling body 10 to the temperature displacement of the conventional wire harness formed by bundling the bundled body W using an adhesive tape instead of the above-mentioned bundling body 10. Fig.15 Describe the temperature shift. Fig.15 is a schematic diagram used to illustrate the temperature displacement of the wiring harness. Fig.15 As shown in FIG. 1 , when one end of the wire harness 100 in the longitudinal direction is fixed to be in a cantilever state and a load M1 is applied to the other end 101 as a free end 101, the wire harness 100 bends and the position of the free end 101 becomes lower than the position of the fixed end 102. Here, when the ambient temperature is low and the temperature of the wire harness 100 is low, the wire harness 100 is not easily deformed. Accordingly, even when the same load M1 is applied to the free end 101, the state of the wire harness becomes Fig.15 The solid line shows the state. When the temperature is low, it becomes Fig.15In the state shown by the dashed line, when the ambient temperature is low, the spacing distance between the free end 101 and the fixed end 102 in the height direction, that is, the maximum bending amount, becomes smaller than when the ambient temperature is high. The inventors of the present application studied the maximum bending amounts when the ambient temperature is 20°C and 4°C. And, the difference dH1 between the maximum bending amount (H2) when the ambient temperature is 20°C and the maximum bending amount (H1) when the ambient temperature is 4°C is calculated as the temperature displacement amount of the wire harness 100. In addition, the temperature displacement amount of the conventional wire harness is also calculated in the same manner. And, as described above, the ratio of the temperature displacement amount of the wire harness 100 to the temperature displacement amount of the conventional wire harness is calculated as the temperature displacement ratio. For example, when the temperature displacement amount of the conventional wire harness is 12 mm and the temperature displacement amount of the wire harness involved in the first embodiment is 6 mm, the temperature displacement ratio is calculated to be 50%.

[0081] A small temperature displacement ratio calculated as described above means that the displacement amount of the wiring harness is not likely to change even if the temperature changes. Based on this, it can be said that when the temperature displacement ratio is small, the performance change of the wiring harness accompanying the temperature change is suppressed to a smaller extent, and the toughness to the temperature change is higher. In addition, it can be said that when the temperature displacement ratio is 100%, the toughness to the temperature change is equal to that of the conventional wiring harness, and when the temperature displacement ratio is less than 100%, the toughness to the temperature change is higher than that of the conventional wiring harness.

[0082] like Fig.14 As shown, both lines L1 and L2 show that when the diameter D of the bundled body W is 15 mm, the temperature displacement ratio is the smallest; the smaller the diameter D is than 15 mm and the larger it is than 15 mm, the greater the temperature displacement ratio is.

[0083] Fig.16 : is a graph showing the relationship between the pitch P and the temperature displacement ratio when the diameter D of the bundled body W is set to 15 mm. Fig.16 As shown, and according to Fig.14 From the comparison of lines L1 and L2, it can be seen that the larger the spacing P, the larger the temperature displacement ratio.

[0084] As described above, if the diameter D of the bundled body W is set to 15 mm, the temperature displacement ratio is reliably reduced. Fig.14 and Fig.16 It can be seen that even when the diameter D of the bundled body W deviates from 15 mm, the temperature displacement ratio can be suppressed to a smaller value according to the pitch P. For example, when the pitch P is 2 mm or less, if the diameter D is 8 mm or more and 20 mm or less, the temperature displacement ratio is suppressed to less than 100%. In addition, if the diameter D is 11 mm or more and 18 mm or less, when the pitch P is 10 mm or less, the temperature displacement ratio is suppressed to less than 75%, and when the pitch P is 2 mm or less, the temperature displacement ratio is suppressed to less than 50%. In addition, if Fig.16As shown in FIG. 1 , when the diameter D of the bundled body W is 15 mm, the temperature displacement ratio can be suppressed to 100% or less by setting the pitch P to 18 mm or less. Furthermore, when the diameter D of the bundled body W is 15 mm, the temperature displacement ratio can be suppressed to 75% or less by setting the pitch P to 16 mm or less. However, if the pitch P is too small, the overall length of the wire S becomes longer, which is disadvantageous in terms of cost, so the pitch P is preferably set to 2 mm or more.

[0085] Based on the above findings, in the first embodiment, the diameter D of the bundled body W is set to a size of 11 mm to 18 mm, and the pitch P is set to a size of 2 mm to 16 mm.

[0086] [Wire harness bundling device]

[0087] Next, the wire harness bundling processing device 200 will be described. Figure 2 It is a perspective view showing the overall structure of the wire harness bundling processing device 200 according to the first embodiment of the present invention. Figure 3 It is a perspective view which enlarges the binding device main body 50. Figure 4 It is from Figure 3 The following are perspective views of the strapping device body 50 as viewed from different directions.

[0088] The wire harness bundling processing device 200 performs a bundling process of bundling a bundled body W including a plurality of wires using a bundling body 10 formed of a flexible wire material S, thereby forming a bundled body as shown in FIG. Figure 1 The device shown is a wire harness 100 having a bundled body 10 in which a plurality of annular portions 20 (a first annular portion 21 and a second annular portion 22) are connected to each other.

[0089] The wire harness bundling processing device 200 performs bundling processing, that is, by repeatedly and continuously performing a connecting step of repeatedly forming the first annular portion 21 and the second annular portion 22 and connecting adjacent first annular portions and second annular portions, thereby connecting multiple annular portions 20 (first annular portion 21, second annular portion 22) to each other.

[0090] More specifically, the connecting step includes two steps, namely, a first connecting step and a second connecting step. The first connecting step is a step of pulling out a portion of the wire S in a manner of passing through the first ring-shaped portion 21 formed by bending another portion of the wire S, thereby forming a second ring-shaped portion 22 connected to the first ring-shaped portion 21. The second connecting step is a step of pulling out a portion of the wire S in a manner of passing through the second ring-shaped portion 22 formed on a portion of the wire S, thereby forming the first ring-shaped portion 21 connected to the second ring-shaped portion 22. The wire harness bundling processing device 200 performs a bundling process of connecting a plurality of ring-shaped portions 20 (the first ring-shaped portion 21, the second ring-shaped portion 22) to each other by alternately and continuously performing the first connecting step and the second connecting step.

[0091] like Figure 2 As shown, the wire harness bundling processing device 200 according to the present embodiment performs a bundling process for bundling the objects to be bundled W placed in the Y-axis direction using the bundling body 10. Therefore, the "longitudinal direction of the objects to be bundled" in the present invention corresponds to the Y-axis direction.

[0092] The wire harness bundling processing device 200 includes a bundling device main body 50 and a guide device 60. The bundling device main body 50 performs a bundling process of bundling the bundled body W placed in the Y-axis direction while moving in the X-axis direction and the Y-axis direction relative to the bundled body W placed in the Y-axis direction, and forming a bundle 10 using wires S. The guide device 60 performs an operation of moving the bundling device main body 50 in the X-axis direction and the Y-axis direction. The operation of the wire harness bundling processing device 200 including the bundling device main body 50 and the guide device 60 is controlled by a control unit (not shown).

[0096] The X-axis guide portion 62 controls the position of the moving portion 64 in the X-axis direction, thereby controlling the position of the strapping device body 50 fixed to the moving portion 64 in the X-axis direction. The X-axis guide portion 62 includes an X-axis fixed guide 621, an X-axis moving portion 622, an X-axis moving guide 623, and an X-axis driving portion 624.

[0097] Two X-axis fixed guides 621 are arranged at intervals in the Y-axis direction, and each is supported by the support portion 61 in a manner parallel to the X-axis direction. Two X-axis moving portions 622 are arranged, and each is supported in a manner movable relative to the X-axis fixed guide 621. The X-axis moving guide 623 is arranged in a manner connecting the two X-axis moving portions 622, and can move in the X-axis direction together with the X-axis moving portion 622 while maintaining a state parallel to the Y-axis direction. The moving portion 64 is supported by the X-axis moving guide 623 in a manner movable in the Y-axis direction.

[0098] The X-axis driving unit 624 moves the X-axis moving unit 622 in the X-axis direction. In the present embodiment, the X-axis driving unit 624 includes a belt, a pulley, a stepping motor, etc. The belt is fixed to the X-axis moving unit 622, and the belt is accurately moved by a specified amount each time by the stepping motor, thereby controlling the position of the X-axis moving unit 622 in the X-axis direction. Accordingly, the position of the moving unit 64 supported by the X-axis moving guide 623 and the strapping device body 50 fixed to the moving unit 64 in the X-axis direction can be controlled.

[0099] The Y-axis guide portion 63 controls the position of the strapping device body 50 fixed to the moving portion 64 in the Y-axis direction by controlling the position of the moving portion 64 in the Y-axis direction. The Y-axis guide portion 63 has substantially the same structure as the X-axis guide portion 62. The Y-axis guide portion 63 includes a Y-axis fixed guide 631, a Y-axis moving portion 632, a Y-axis moving guide 633, and a Y-axis driving portion 634.

[0100] Two Y-axis fixed guides 631 are arranged at intervals in the X-axis direction, and each is supported by the support portion 61 in a manner parallel to the Y-axis direction. Two Y-axis moving portions 632 are arranged, and each is supported in a manner movable relative to the Y-axis fixed guide 631. The Y-axis moving guide 633 is arranged in a manner connecting the two Y-axis moving portions 632, and can move in the Y-axis direction together with the Y-axis moving portion 632 while maintaining a state parallel to the X-axis direction. The moving portion 64 is supported by the Y-axis moving guide 633 in a manner movable in the X-axis direction.

[0101] The Y-axis driving unit 634 moves the Y-axis moving unit 632 in the Y-axis direction. In the present embodiment, the Y-axis driving unit 634 includes a belt, a pulley, a stepping motor, etc. The belt is fixed to the Y-axis moving unit 632, and the stepping motor is used to accurately move the belt by a specified amount each time, thereby controlling the position of the Y-axis moving unit 632 in the Y-axis direction. Accordingly, the position of the moving unit 64 supported by the Y-axis moving guide 633 and the strapping device body 50 fixed to the moving unit 64 in the Y-axis direction can be controlled.

[0102] By controlling the position of the moving portion 64 in the X-axis direction and the Y-axis direction by the guide device 60 , the position of the binding device main body 50 fixed to the moving portion 64 in the X-axis direction and the Y-axis direction can be controlled.

[0103] [Bundling device body]

[0104] like Figure 3 and Figure 4 As shown, the bundling device body 50 includes a wire supply unit 70 and a loop forming unit 80. The wire supply unit 70 supplies wire S to the loop forming unit 80 near the bundled body W (see FIG. Figure 5 The ring-shaped forming unit 80 forms a plurality of ring-shaped portions 20 (a first ring-shaped portion 21 and a second ring-shaped portion 22 ) using the wire material S supplied from the wire material supplying unit 70 .

[0105] The wire supply unit 70 and the ring forming unit 80 perform a bundling process for bundling the bundled objects W by forming a bundle 10 using the wires S while moving the bundled objects W placed along the Y-axis direction in the X-axis direction and the Y-axis direction via the guide device 60 (see Figure 8 ).

[0106] The binding device body 50 is provided with a wire supply drive unit 51, a first loop forming drive unit 52, and a second loop forming drive unit 53. The wire supply drive unit 51 drives the wire supply unit 70. The first loop forming drive unit 52 and the second loop forming drive unit 53 drive the loop forming unit 80.

[0107] The annular forming part 80 is configured to be movable in the Z-axis direction, and the first annular forming driving part 52 drives the annular forming part 80 in the Z-axis direction. In the present embodiment, the first annular forming driving part 52 includes a toggle mechanism, a stepping motor, etc. One connecting rod of the toggle mechanism is fixed to the stepping motor, and the other connecting rod of the toggle mechanism is fixed to the annular forming part 80. The position of the annular forming part 80 in the Z-axis direction is controlled by rotating the connecting rod of the toggle mechanism by a specified amount using the stepping motor.

[0108] The operating portion 81 constituting the ring-shaped forming portion 80 (see Figure 5 ) is configured to be rotatable around the Z axis, and the second ring-shaped forming driving unit 53 rotates the operating unit 81 around the Z axis. The second ring-shaped forming driving unit 53 has a stepping motor. The direction of the operating unit 81 is controlled by rotating the operating unit 81 by a specified amount using the stepping motor.

[0109] [Wire material supply department]

[0110] Figure 5 This is a diagram of the strapping device body 50 as viewed from the Y-axis direction. Figure 5As shown, the wire supply unit 70 supplies the wire S to the ring forming unit 80 near the bundled body W. The wire supply unit 70 includes a storage unit (not shown), a tension adjustment unit (not shown), and a wire hanging unit 71 (see Figure 6 ).

[0111] The storage unit is, for example, a bobbin around which the wire S is wound, and stores and supplies the wire S. The storage unit is disposed, for example, below the bundling device main body 50 .

[0112] The tension adjusting unit is a mechanism for applying appropriate tension to the wire S. The tension adjusting unit is disposed between the storage unit and the wire hanging unit 71. The tension adjusting unit may be a mechanism utilizing gravity such as a weight or a mechanism utilizing elastic force of an elastic body such as a spring.

[0113] The wire material hanging part 71 performs the operation of hanging the wire material S on the operation part 81 of the loop forming part 80. The wire material hanging part 71 includes a hanging part body 72 and an arm 73 (see Figure 6 The hanging part body 72 is a substantially disc-shaped member. The hanging part body 72 is formed with an insertion hole 74 and a supply hole 75. The distal end portion (locking portion 812) of the operating portion 81 of the ring-shaped forming portion 80 can be inserted into the insertion hole 74 (see Figure 7 (b) The wire material S supplied from the storage portion passes through the supply hole portion 75 .

[0114] The arm 73 is provided so as to protrude laterally from the hanging portion main body 72. A roller 76 is provided inside the arm 73. The wire S passing through the supply hole 75 is supplied to the bundled body W via the roller 76.

[0115] The wire material supply driving unit 51 (see Figure 3 The wire rod hanging portion 71 is configured to rotate about the Z axis by the wire rod supply driving portion 51 (see Figure 6 The operation of the wire hanging section 71 will be described in detail later.

[0116] [Ring-shaped forming part]

[0117] The loop forming section 80 forms a plurality of loop portions 20 (a first loop portion 21 and a second loop portion 22 ) using the wire S supplied from the wire supply section 70 . The loop forming section 80 includes an operation section 81 and a pressing section 82 .

[0118] The operating portion 81 is a member that temporarily holds or grips the wire S and performs operations on the wire S. Specifically, the operating portion 81 performs an operation of forming the ring-shaped portion 20 by bending a portion of the wire S. In addition, the operating portion 81 performs an operation of forming the next ring-shaped portion 20 and passing it through the ring-shaped portion 20 formed on the wire S (see FIG. 9A to FIG. 9D) In the present embodiment, a hook-shaped member having a locking portion 812 at the distal end of a shaft portion 811 is used as the operating portion 81, but the shape and structure of the operating portion 81 are not limited.

[0119] The pressing portion 82 is a member for operating the wire S together with the operating portion 81. In the present embodiment, the pressing portion 82 is a cylindrical member, and a through portion 821 for inserting the operating portion 81 is formed at the center. The operating portion 81 can move along the Z-axis direction relative to the pressing portion 82. In addition, the operating portion 81 and the pressing portion 82 can also move along the Z-axis direction at the same time. Moreover, the operating portion 81 can rotate relative to the pressing portion 82 with the Z-axis as the center.

[0120] [Operation of the wire supply unit]

[0121] Figure 6 It is a diagram for explaining the operation of the wire hanging section 71. Figure 6 (a) shows an example of the posture of the wire hanging part 71, and the arm 73 is stopped in a state facing the upper left in the figure. The locking part 812 of the operation part 81 is inserted into the insertion hole 74 (refer to Figure 7 (b) The end portion of the wire S supplied from the supply hole 75 extends downward in the figure and is not caught on the operation portion 81 inserted into the insertion hole 74 .

[0122] Figure 6 (b) shows the hanging portion main body 72 from Figure 6 (a) is rotated rightward as shown in the figure. The hanging part body 72 rotates until the arm 73 faces the lower right side as shown in the figure and then stops. In this state, the wire S supplied from the supply hole 75 surrounds the operation part 81 in a curved state (see Fig. 9A (b)). Figure 6 In the state (b), by pulling the operating portion 81 upward from the insertion hole 74, the bent portion of the wire S is locked on the locking portion 812 of the operating portion 81. By hooking the wire S on the locking portion 812 of the operating portion 81, the operating portion 81 can perform operations on the wire S such as pulling the wire S upward ( Fig. 9A (c)).

[0123] [Movement of the strapping device body in the Z-axis direction]

[0124] Figure 7 2 is a diagram for explaining the operation of the strapping device body 50 in the Z-axis direction. Figure 7 (a)~ Figure 7 As shown in (d), the wire supply unit 70 (wire hanging unit 71) is fixed to the bundling device body 50, and the position in the Z-axis direction does not change (see Figure 4 , Figure 5). In contrast, the ring-shaped forming portion 80 (operating portion 81, pressing portion 82) is configured to be movable in the Z-axis direction. Therefore, by moving the ring-shaped forming portion 80 (operating portion 81, pressing portion 82) in the Z-axis direction, the relative positional relationship between the wire supply portion 70 (wire hanging portion 71) and the ring-shaped forming portion 80 (operating portion 81, pressing portion 82) in the Z-axis direction can be changed. Figure 7 (a)~ Figure 7 The operations shown in (d) are described below.

[0125] exist Figure 7 In the action shown in (a), the locking portion 812 of the operating portion 81 is separated from the insertion hole portion 74 of the wire hanging portion 71 and is located in the +Z axis direction (upper) relative to the insertion hole portion 74. In addition, the locking portion 812 of the operating portion 81 is also separated from the insertion portion 821 of the pressing portion 82 and is located below the insertion portion 821.

[0126] exist Figure 7 In the operation shown in (b), the operation unit 81 is relative to Figure 7 (a) The locking portion 812 of the operating portion 81 is inserted into the insertion hole 74 of the wire hanging portion 71 when the operating portion 81 is lowered in the Z-axis direction. Figure 7 (a)No change.

[0127] exist Figure 7 In the operation shown in (c), the operation unit 81 is relative to Figure 7 (a) and (b) are raised in the +Z-axis direction, and the locking portion 812 of the operating portion 81 is inserted into the insertion portion 821 of the pressing portion 82. The position of the pressing portion 82 in the Z-axis direction is relative to Figure 7 There is no change in (a) and (b).

[0128] exist Figure 7 In the operation shown in (d), the operation portion 81 and the pressing portion 82 are relative to each other. Figure 7 (c) Both rise in the +Z axis direction. The locking portion 812 of the operation portion 81 is kept inserted in the insertion portion 821 of the pressing portion 82 and rises together with the pressing portion 82 .

[0129] [Movement of the strapping device body in the X-axis direction and the Y-axis direction]

[0130] Figure 8 2 is a diagram for explaining the operation of the strapping device body 50 in the X-axis direction and the Y-axis direction. Figure 8As shown, the wire supply unit 70 (wire hanging unit 71) and the loop forming unit 80 (operating unit 81, pressing unit 82) constituting the bundling device main body 50 move in the X-axis direction and the Y-axis direction relative to the bundled object W provided in the wire harness bundling processing device 200 while maintaining the relative positions in the X-axis direction and the Y-axis direction. The movement of the bundling device main body 50 in the X-axis direction and the Y-axis direction is performed by the position control of the guide device 60 as described above.

[0131] The movement of the strapping device body 50, such as Figure 8 Specifically, the bundling device body 50 moves in the X-axis direction so that the wire supply unit 70 and the ring forming unit 80 are alternately located on the +X side and -X side of the bundled body W, and also moves in the +Y-axis direction by a specified distance at a time.

[0132] When the wire supply unit 70 and the ring forming unit 80 move toward the +X side and the -X side of the bundled body W, the wire supply unit 70 passes through the -Z side (below the bundled body W). The ring forming unit 80 passes through the +Z side (above the bundled body W). Figure 8 In the embodiment, the strapping device body 50 moves a specified distance in the +Y axis direction each time it reciprocates in the X axis direction. However, the distance moved in the +Y axis direction may be changed as required.

[0133] [Bundling Processing Operation by the Wire Harness Bundling Processing Device]

[0134] The wire harness bundling processing device 200 performs bundling processing as described above, that is: by repeatedly and continuously performing the connection steps (first connection step and second connection step) of repeatedly forming the first ring-shaped portion 21 and the second ring-shaped portion 22, and connecting the adjacent first ring-shaped portion and the second ring-shaped portion, thereby connecting multiple ring-shaped portions 20 (first ring-shaped portion 21, second ring-shaped portion 22) to each other.

[0135] like Figure 8 As shown, in this embodiment, the first connection step is performed in a state where the bundling device main body 50 (wire supply part 70 and loop forming part 80) is located on the +X side of the bundled body W and is moved from the +X side to the -X side. In addition, the second connection step is performed in a state where the bundling device main body 50 (wire supply part 70 and loop forming part 80) is located on the -X side of the bundled body W and is moved from the -X side to the +X side.

[0136] That is, the first connection step is performed when the binding device body 50 (wire supply unit 70 and loop forming unit 80) is located at, for example, P1 and on the path M1 moving from P1 to P2. Similarly, the first connection step is performed between P3 and the path M3, P5 and the path M5, and P7 and the path M7.

[0137] The first connecting step is a step of connecting the second annular portion 22 to the first annular portion 21. Specifically, a portion of the wire S is pulled out by passing through the first annular portion 21 formed by bending another portion of the wire S, thereby forming the second annular portion 22 connected to the first annular portion 21.

[0138] The second connection step is performed when the binding device body 50 (wire supply unit 70 and loop forming unit 80) is located at P2 and on the path M2 moving from P2 to P3. Similarly, the second connection step is performed between P4 and path M4, P6 and path M6, and P8 and path M8.

[0139] The second connection step is a step of connecting the first annular portion 21 to the second annular portion 22. Specifically, a portion of the wire S is pulled out through the second annular portion 22 formed on a portion of the wire S, thereby forming the first annular portion 21 connected to the second annular portion 22.

[0140] [1st bundling step]

[0141] Next, the operation of the binding device main body 50 (the wire supplying section 70 and the loop forming section 80) in the first connecting step will be described in detail. Fig. 9A (a)~ Fig.9D (j) is a diagram illustrating the first connection step. Fig. 9A (a)~ Fig.9D (j) schematically shows the wire hanging portion 71 of the wire supply portion 70, the operating portion 81 and the pressing portion 82 of the ring forming portion 80, and the first ring portion 21 and the second ring portion 22 formed by the wire S when viewed from the +Y axis direction.

[0142] set up Fig. 9A (a)~ Fig.9D The first connection step shown in (j) is to place the binding device main body 50 (wire supply unit 70 and loop forming unit 80) in the Figure 8 The description will be made based on the state at P1 and the state on the path M1 moving from P1 to P2.

[0143] In addition, the first connection step and the second connection step are in a relationship in which the first annular portion 21 and the second annular portion 22 are exchanged. Therefore, in the second connection step, Fig. 9A (a)~ Fig.9D(j) The first annular portion 21 and the second annular portion 22 are interchanged.

[0144] Fig. 9A (a) is Figure 8 At the position P1, the operation part 81 is lowered in the -Z axis direction, and the locking part 812 of the operation part 81 is inserted into the insertion hole 74 of the wire hanging part 71. The wire S is bent by wrapping around the shaft 811 of the operation part 81. The portion bent around the shaft 811 forms the first annular part 21. Fig. 9A The portion of the wire S that is bent around the shaft 811 in (a) is the portion that is hooked and bent by the locking portion 812 of the operating portion 81 in the previous step (not shown). By lowering the operating portion 81 from the state where the wire S is hooked by the locking portion 812 of the operating portion 81, the shaft 811 of the operating portion 81 passes through the bent portion of the wire S (the state where the wire S is wrapped).

[0145] Fig. 9A (b) The wire S is wrapped around the operation part 81 by rotating the wire hanging part 71 (see Figure 6 (b) The portion of the wire hanging portion 71 that is bent around the operation portion 81 forms the second annular portion 22 .

[0146] Fig. 9A (c) The operation portion 81 is pulled upward from the insertion hole 74 in the +Z axis direction and the operation portion 81 is moved relative to the Fig. 9A (b) After being rotated about 90 degrees around the Z axis, the portion forming the second annular portion 22 is locked in the locking portion 812 of the operating portion 81. The portion forming the first annular portion 21 around the shaft portion 811 of the operating portion 81 is also pulled upward together with the operating portion 81 due to friction.

[0147] Fig. 9B (d) is to pull the operating part 81 further upward in the +Z axis direction and make the operating part 81 relative to Fig. 9A (b) After being rotated about 180 degrees around the Z axis, the portion forming the second annular portion 22 is locked to the locking portion 812 of the operating portion 81. The portion forming the first annular portion 21 around the shaft portion 811 of the operating portion 81 is also pulled upward together with the operating portion 81.

[0148] Fig. 9B(e) is a state in which the operating portion 81 is further pulled upward in the +Z axis direction, so that the locking portion 812 of the operating portion 81 is inserted into the insertion portion 821 of the pressing portion 82. In this state, the portion of the first annular portion 21 formed around the shaft portion 811 of the operating portion 81 cannot rise because it contacts the lower edge of the pressing portion 82, and the operating portion 81 and the portion of the second annular portion 22 hooked by the locking portion 812 of the operating portion 81 are pulled upward.

[0149] Fig. 9B (f) is a state in which the locking portion 812 of the operating portion 81 is inserted into the insertion portion 821 of the pressing portion 82 by further pulling the operating portion 81 upward in the +Z axis direction (see Figure 7 (c)). In this state, the portion of the first annular portion 21 formed by surrounding the shaft portion 811 of the operating portion 81 is pushed out by the lower edge of the pressing portion 82. On the other hand, the portion of the second annular portion 22 hooked by the locking portion 812 of the operating portion 81 is inserted into the insertion portion 821 of the pressing portion 82. That is, by pulling out a portion of the wire S in a manner that passes through the first annular portion 21, the second annular portion 22 connected to the first annular portion 21 is formed.

[0150] exist Fig. 9C In (g), both the operation part 81 and the pressing part 82 rise in the +Z axis direction. The locking part 812 of the operation part 81 rises together with the pressing part 82 while being inserted into the insertion part 821 of the pressing part 82 (see Figure 7 (d)). By this action, the second annular portion 22 is pulled out relatively to a greater extent than the first annular portion 21. Figure 8 The movement from P1 to P2 is coordinated so that the operating portion 81 and the pressing portion 82 do not interfere with the bundled body W.

[0151] Fig. 9C (h) The operation part 81 and the pressing part 82 are both Figure 8 The locking portion 812 of the operation portion 81 is kept inserted in the insertion portion 821 of the pressing portion 82 and rises together with the pressing portion 82 (see Figure 7 (d)). By this action, the second annular portion 22 is pulled out relatively to the first annular portion 21. In addition, the wire supply portion 70 and the annular forming portion 80 move relative to the bundled body W from the position P1 to the position P2, so that the operating portion 81 and the pressing portion 82 do not interfere with the bundled body W and rise in the +Z axis direction.

[0152] exist Fig.9D (i) The operating part 81 and the pressing part 82 are both in Figure 8 The position P2 descends in the Z-axis direction.

[0153] exist Fig.9D In (j), the operation portion 81 is lowered in the -Z-axis direction relative to the pressing portion 82. As the operation portion 81 is lowered, the second annular portion 22 locked in the locking portion 812 moves and surrounds the shaft portion 811.

[0154] from Fig.9D (j) status, Figure 8 At position P2, the connection step is switched from the first connection step to the second connection step. Figure 8 As shown in FIG. 1 , the following steps are repeatedly and continuously performed while the bundled body W is moved in the X-axis direction and the Y-axis direction. Fig. 9A (a)~ Fig.9D (j) The first connection step and Fig. 9A (a)~ Fig.9D In the second connecting step (j), the first annular portion 21 and the second annular portion 22 are exchanged, thereby performing a bundling process of connecting the plurality of annular portions 20 (the first annular portion 21 and the second annular portion 22) to each other.

[0155] [Wire harness bundling method]

[0156] Fig.10 The wire harness bundling method according to the present embodiment repeatedly and continuously performs a connecting step of repeatedly forming the first annular portion 21 and the second annular portion 22 and connecting adjacent first annular portions and second annular portions.

[0157] The connecting step includes a first connecting step and a second connecting step. The first connecting step is a step of forming a second annular portion 22 connected to the first annular portion 21 by drawing out a portion of the wire S so as to pass through the first annular portion 21 formed by bending another portion of the wire S. In addition, the second connecting step is a step of drawing out a portion of the wire S so as to pass through the second annular portion 22 formed on a portion of the wire S, thereby forming the first annular portion 21 connected to the second annular portion 22.

[0158] like Fig.10 As shown in FIG. 1 , if the bundling process starts, the first connection step (SA1) and the second connection step (SA2) are performed continuously. When the length of the bundling process reaches the set length (SA3 is YES), the bundling process is terminated. When the length of the bundling process does not reach the set length (SA3 is NO), the bundling process (SA1) is continued.

[0159] According to the wire harness 100 according to the present embodiment described above, the bundled body 10 has a plurality of continuously formed annular portions 20 (a first annular portion 21 and a second annular portion 22), the plurality of annular portions 20 are arranged along the longitudinal direction of the bundled body W, and the adjacent annular portions 20 are connected to each other, so that the bundled body W is bundled.

[0160] Since the objects to be bundled W are continuously bundled using the bundling body 10 formed of the flexible wires S, the work of bundling the electric wires using the bundling body 10 can be automated and accelerated.

[0161] Furthermore, since the objects to be bundled W are bundled by connecting the adjacent annular portions 20 to each other, the position of the bundled body 10 relative to the objects to be bundled W is less likely to shift, and a reduction in the bundling force for bundling the electric wires can be suppressed.

[0162] Furthermore, according to the wire harness bundling processing device 200 and the wire harness bundling processing method according to the present embodiment, the plurality of ring-shaped portions 20 are connected to each other by connecting the adjacent first ring-shaped portion 21 and the second ring-shaped portion 22 .

[0163] Since the first annular portion 21 and the second annular portion 22 are repeatedly formed and connected, the work of bundling the electric wires using the bundling body 10 can be accelerated.

[0164] [Implementation Method 2]

[0165] Next, a wire harness 300 according to Embodiment 2 (second embodiment) of the present invention will be described. Fig.17 2 is a side view showing a wire harness 300 according to the second embodiment. The second embodiment differs from the first embodiment in the structure of the connection portion between the annular portions 20, and the other structures are the same. In the following description of the second embodiment, the same elements as those of the first embodiment are described using the same reference numerals as those of the first embodiment, and the detailed description of the structure is omitted. Fig.17 In the present invention, the same elements as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment.

[0166] Similar to the first embodiment, the bundled body 301 of the wire harness 300 involved in the second embodiment includes: the first annular portion 21 including the first portion 21A and the second portion 21B and arranged on the first circumferential surface W_A; the second annular portion 22 including the third portion 22A and the fourth portion 22B and arranged on the first circumferential surface W_A; the first restraining portion 31 extending from the base end portion 23 of the first annular portion 21 around the second circumferential surface W_B to the distal end portion 24; and the second restraining portion 32 extending from the base end portion 25 of the second annular portion 22 around the second circumferential surface W_B to the distal end portion 26.

[0167] In the following description of the second embodiment, the longitudinal direction of the bundled body W is appropriately referred to as the left-right direction, and Fig.17 In the description, the right side, that is, the base end portion 23 side of the first annular portion 21 relative to the distal end portion 24 is referred to as the right, and the opposite side is referred to as the left.

[0168] As in the first embodiment, in the wire harness 300 according to the second embodiment, the base end of each annular portion 20 is connected to the distal end of another adjacent annular portion 20. However, in the second embodiment, the bundled body 301 is provided with a connecting portion, and the base end of each annular portion 20 is connected to the distal end of another annular portion 20 by the connecting portion.

[0169] The distal end portion 24 of the first annular portion 21 (211) is connected to the base end portion 25 of the second annular portion 22 (221) adjacent to the first annular portion 21 (211) on the left side through the first connecting portion 310. That is, the bundled body 301 has the first connecting portion 310 connecting the distal end portion 24 of the first annular portion 21 (211) and the base end portion 25 of the second annular portion 22 (221) adjacent to the first annular portion 21 (211) on the left side. In addition, the base end portion 23 of the first annular portion 21 (212) is connected to the distal end portion 26 of the second annular portion 22 (221) adjacent to the first annular portion 21 (212) on the right side through the second connecting portion 320. That is, the bundled body 301 has a second connecting portion 320 that connects the base end portion 23 of the first annular portion 21 (212) and the distal end portion 26 of the second annular portion 22 (221) adjacent to the first annular portion 21 (212) on the right side. Fig.17 In the figure, the connection parts 310 and 320 are shaded to make them clearly visible.

[0170] The first connection portion 310 and the second connection portion 320 are formed by chain weaving the wire S in a state where the wire S does not surround the bundled body W. That is, in the second embodiment, as in the first embodiment, one wire S is chain weaved in a manner to surround the bundled body W to form the bundled body 301. However, in the second embodiment, the wire S is woven so that only one of the two continuous loops formed by chain weaving surrounds the bundled body W, and the other loop does not surround the bundled body W. The loop formed in a manner not to surround the bundled body W constitutes the above-mentioned connection portions 310 and 320.

[0171] Specifically, the first connection portion 310 is roughly annular. The first connection portion 310 is formed by a wire S connecting the first constraint portion 31 and the third portion 22A, and is directly connected to the first constraint portion 31 and the third portion 22A, respectively. The first connection portion 310 passes through the distal end portion 24 of the first annular portion 21 in a state where both ends thereof are wound around the distal end portion 24 of the first annular portion 21. A gap is formed between the first connection portion 310 and the distal end portion 24 of the first annular portion 21. The right end portion 25A of the third portion 22A and the right end portion 25B of the fourth portion 22B constituting the base end portion 25 of the second annular portion 22 pass through the above-mentioned gap, and the first connection portion 310 is wound around the base end portion 25 of the second annular portion 22. Thus, the first connection portion 310 is wound around the distal end portion 24 of the first annular portion 21 and the proximal end portion 25 of the second annular portion 22 , thereby connecting the distal end portion 24 of the first annular portion 21 and the proximal end portion 25 of the second annular portion 22 .

[0172] The second connection portion 320 is substantially annular. The second connection portion 320 is formed by a wire S connecting the second constraint portion 32 and the first portion 21A, and is directly connected to the second constraint portion 32 and the first portion 21A, respectively. The second connection portion 320 passes through the distal end portion 26 of the second annular portion 22 in a state where both ends thereof are wound around the distal end portion 26 of the second annular portion 22. A gap is formed between the second connection portion 320 and the distal end portion 26 of the second annular portion 22. The right end portion 23A of the first portion 21A and the right end portion 23B of the second portion 21B constituting the base end portion 23 of the first annular portion 21 pass through the above-mentioned gap, and the second connection portion 320 is wound around the base end portion 23 of the first annular portion 21. Thus, the second connection portion 320 is wound around the distal end portion 26 of the second annular portion 22 and the proximal end portion 23 of the first annular portion 21 , thereby connecting the distal end portion 26 of the second annular portion 22 and the proximal end portion 23 of the first annular portion 21 .

[0173] In the wire harness 300 according to the second embodiment configured as described above, adjacent annular portions 20 (first annular portion 21, second annular portion 22) are connected to each other, respectively, and the first restraining portion 31 and the second restraining portion 32 are formed so as to surround the circumference of the bundled body W. Then, the first restraining portion 31 and the second restraining portion 32 fasten the bundled body W by the tension applied to the wire S, and the bundled body W is bundled using the bundling body 301.

[0174] Furthermore, in the wire harness 300 according to the second embodiment, similarly to the first embodiment, adjacent annular portions 20 (the first annular portion 21, the second annular portion 22) are connected to each other, so that the movement of the wires S is restrained due to friction between the wires S, etc., and the reduction in tension applied to the wires S is also suppressed, thereby suppressing the reduction in the bundling force for bundling the bundled body W.

[0175] In the wire harness 300 according to the second embodiment, the first connection portion 310 is provided in the bundle body 301 to connect the distal end portion 24 of the first annular portion 21 and the proximal end portion 25 of the second annular portion 22, and the connection structure thereof is complicated. Similarly, the second connection portion 320 is provided in the bundle body 301 to connect the distal end portion 26 of the second annular portion 22 and the proximal end portion 23 of the first annular portion 21, and the connection structure thereof is complicated. Therefore, it is possible to prevent the connection between the distal end portion 24 of the first annular portion 21 and the proximal end portion 25 of the second annular portion 22, and the connection between the distal end portion 26 of the second annular portion 22 and the proximal end portion 23 of the first annular portion 21 from being easily released. For example, in the case where the wire S is damaged in the middle portion thereof, it is possible to prevent the connection between the first annular portion 21 and the second annular portion 22 from being released, and it is possible to prevent the wire S from being loosened and the bundling force of the bundle body W from being reduced.

[0176] In addition, the first connecting portion 310 is formed of a wire S connecting the first constraint portion 31 and the third portion 22A, and is wound around the base end portion 25 of the second annular portion 22 and the distal end portion 24 of the first annular portion 21 to connect them. Therefore, at the connection portion between the distal end portion 24 of the first annular portion 21 and the base end portion 25 of the second annular portion 22, the friction between the wire S can be increased, so that the movement of the wire S can be more strongly restrained. Similarly, the second connecting portion 320 is formed of a wire S connecting the second constraint portion 32 and the first portion 21A, and is wound around the distal end portion 26 of the second annular portion 22 and the base end portion 23 of the first annular portion 21 to connect them. Therefore, at the connection portion between the distal end portion 26 of the second annular portion 22 and the base end portion 23 of the first annular portion 21, the friction between the wire S can be increased, so that the movement of the wire S can be more strongly restrained.

[0177] [Implementation method 3]

[0178] Next, a wire harness 400 according to Embodiment 3 (third embodiment) of the present invention will be described. Fig.18 It is a schematic front view showing a wire harness 400 according to the third embodiment. Fig.19 Yes means Fig.18 It is a schematic rear view of the wire harness 400 shown. In the following description of the third embodiment, detailed description of the same elements as those of the first embodiment will be omitted.

[0179] In the wire harness 400 according to the third embodiment, the bundled body W includes: a first bundled body W100 extending in a predetermined direction; and a second bundled body W200 and a third bundled body W300 branching from the end of the first bundled body W100 in two different directions. Fig.18In the example, the second bundled body W200 and the third bundled body W300 extend in opposite directions from the end of the first bundled body W100. Each of the bundled bodies W100, W200, and W300 includes a plurality of wires. In addition, each of the bundled bodies W100, W200, and W300 has a first circumferential surface W_A which is one of the two circumferentially divided circumferential surfaces thereof and a second circumferential surface W_B which is the opposite side of the first circumferential surface W_A. Each first circumferential surface W_A is a surface on which the annular portion 420 described later is arranged. Each first circumferential surface W_A of the second bundled body W200 and the third bundled body W300 is continuous with the first circumferential surface W_A of the first bundled body W100 at the branching portion W409 where the second bundled body W200 and the third bundled body W300 branch.

[0180] In the wire harness 400 according to the third embodiment, the bundled body W is bundled near the branch portion W409 using a bundled body 410 formed of a flexible wire S. In the third embodiment, similarly to the first embodiment, the bundled body 410 has a plurality of ring-shaped portions 420 each formed by bending a portion of the wire S. However, in the third embodiment, the bundled body 410 has only three ring-shaped portions 420, namely, a first ring-shaped portion 421, a second ring-shaped portion 422, and a third ring-shaped portion 440 as the ring-shaped portions 420.

[0181] The first annular portion 421 is generally annular and is formed to extend on the first circumferential surface W_A of the second bundled body W200 in a direction intersecting the longitudinal direction of the second bundled body W200. The first annular portion 421 extends from the first inner corner portion 401 where the first bundled body W100 and the second bundled body W200 intersect toward the third bundled body W300. Fig.18 In the figure, the first annular portion 421 extends downward and leftward from the first inner corner portion 401 located at the right end of the lower end portion of the first bundled body W100.

[0182] The end of the first annular portion 421 located on the opposite side of the first inner corner portion 401 in the extending direction thereof is annular, and the first annular portion 421 includes: a first portion 421A extending from the end on one side in the extending direction thereof and on the first inner corner portion 401 side, that is, a base end portion 423, to the end on the other side, that is, a distal end portion 424; and a second portion 421B returning from the distal end portion 424 to the base end portion 423. The base end portion 423 of the first annular portion 421 includes: the first portion 421A; and ends 423A and 423B located on the first inner corner portion 401 side of the second portion 421B.

[0183] The second annular portion 422 is roughly annular and is formed to extend on the first circumferential surface W_A of the third bundled body W300 in a direction intersecting the length direction of the third bundled body W300. The second annular portion 422 extends from the portion where the second bundled body W200 and the third bundled body W300 intersect, that is, their boundary portion, that is, the second inner corner portion 402, in a direction intersecting the length direction of the third bundled body W300. The second annular portion 422 extends from the second inner corner portion 402 to the third inner corner portion 403 where the third bundled body W300 and the first bundled body W100 intersect. Fig.18 In the embodiment, the second annular portion 422 extends from the second inner corner portion 402 toward the upper left side toward the third inner corner portion 403 located at the left end of the lower end portion of the first bundled body W100.

[0184] The end of the second annular portion 422 located on the opposite side of the second inner corner portion 402 in the extension direction thereof is annular, and the second annular portion 422 includes: a third portion 422A extending from a base end portion 425, which is an end portion on one side of the extension direction and on the second inner corner portion 402 side, to a distal end portion 426, which is an end portion on the other side; and a fourth portion 422B returning from the distal end portion 426 to the base end portion 425. The base end portion 425 of the second annular portion 422 includes: the third portion 422A; and ends 425A and 425B located on the second inner corner portion 402 side of the fourth portion 422B.

[0185] The third annular portion 440 is substantially annular and is formed to extend on the first circumferential surface W_A of the first bundled body W100 in a direction intersecting the longitudinal direction of the first bundled body W100. The third annular portion 440 extends from the third inner corner portion 403 to the first inner corner portion 401. Fig.18 In the figure, the third annular portion 440 extends leftward from the third inner corner portion 403.

[0186] The end of the third annular portion 440 located on the opposite side of the third inner corner portion 403 in the extending direction thereof is annular, and the third annular portion 440 includes: a fifth portion 440A extending from the end on one side in the extending direction thereof and on the side of the third inner corner portion 403, that is, the base end portion 427, to the end on the other side, that is, the distal end portion 428; and a sixth portion 440B returning from the distal end portion 428 to the base end portion 427. The base end portion 427 of the third annular portion 440 includes: the fifth portion 440A; and the ends 427A and 427B located on the side of the third inner corner portion 403 in each of the sixth portion 440B.

[0187] In addition, since the first annular portion 421, the second annular portion 422 and the third annular portion 440 are formed of the flexible wire S, the shapes of the annular portions 421, 422, 440 vary depending on the material of the wire S and the tension applied to the wire S, and are not limited to Fig.18 The shape shown. In addition, the size (length) of each annular portion 421, 422, 440 can be the same or different. In addition, the ratio of the size (length) of each annular portion 421, 422, 440 to the thickness (diameter) of the bundled body W is not limited.

[0188] The base end portion 425 of the second annular portion 422 passes through the distal end portion 424 of the first annular portion 421, and the distal end portion 424 of the first annular portion 421 is wound around the base end portion 425 of the second annular portion 422. In other words, the base end portion 425 of the second annular portion 422 is hooked by the distal end portion 424 of the first annular portion 421, and the base end portion 425 of the second annular portion 422 and the distal end portion 424 of the first annular portion 421 are connected.

[0189] The base end portion 427 of the third annular portion 440 passes through the distal end portion 426 of the second annular portion 422, and the distal end portion 426 of the second annular portion 422 is wound around the base end portion 427 of the third annular portion 440. In other words, the base end portion 427 of the third annular portion 440 is hooked by the distal end portion 426 of the second annular portion 422, and the base end portion 427 of the third annular portion 440 and the distal end portion 426 of the second annular portion 422 are connected.

[0190] As described above, in the wire harness 400 according to the third embodiment, the first annular portion 421 and the second annular portion 422 are connected, and the second annular portion 422 and the third annular portion 440 are connected.

[0191] like Fig.18 and Fig.19 As shown, the bundled body 410 includes a first restraining portion 431 , a second restraining portion 432 , and a third restraining portion 433 , each of which is formed of a wire S.

[0192] The first restraining portion 431 extends from the base end portion 423 of the first annular portion 421 around the second peripheral surface W_B of the second bundled body W200 to the distal end portion 424 of the first annular portion 421. The second restraining portion 432 extends from the base end portion 425 of the second annular portion 422 around the second peripheral surface W_B of the third bundled body W300 to the distal end portion 426 of the second annular portion 422. The third restraining portion 433 extends from the base end portion 427 of the third annular portion 440 around the second peripheral surface W_B of the first bundled body W100 to the distal end portion 428 of the third annular portion 440.

[0193] The first annular portion 421 and the first restraining portion 431 are arranged so as to surround the circumference of the second bundled body W200, and the entire circumference of the circumference of the second bundled body W200 is surrounded by the first annular portion 421 and the first restraining portion 431. The second annular portion 422 and the second restraining portion 432 are arranged so as to surround the circumference of the third bundled body W300, and the entire circumference of the circumference of the third bundled body W300 is surrounded by the second annular portion 422 and the second restraining portion 432. The third annular portion 440 and the third restraining portion 433 are arranged so as to surround the circumference of the first bundled body W100, and the entire circumference of the circumference of the first bundled body W100 is surrounded by the third annular portion 440 and the third restraining portion 433.

[0194] The first restraining portion 431 is directly connected to the second portion 421B at the base end portion 423 of the first annular portion 421, and is directly connected to the third portion 422A at the base end portion 425 of the second annular portion 422. In this way, the first restraining portion 431 is formed by the wire S extending from the end 423B of the second portion 421B constituting the base end portion 423 of the first annular portion 421 to the end 425A of the third portion 422A constituting the base end portion 425 of the second annular portion 422.

[0195] The second constraint portion 432 is directly connected to the fourth portion 422B at the base end portion 425 of the second annular portion 422, and is directly connected to the fifth portion 440A at the base end portion 427 of the third annular portion 440. In this way, the second constraint portion 432 is formed by the wire S extending from the end 425B of the fourth portion 422B constituting the base end portion 425 of the second annular portion 422 to the end 427A of the fifth portion 440A constituting the base end portion 427 of the third annular portion 440.

[0196] The third restraining portion 433 is directly connected to the sixth portion 440B at the base end portion 427 of the third annular portion 440, and is formed by a wire S extending from an end portion 427B of the sixth portion 440B constituting the base end portion 427 of the third annular portion 440. Fig.18 As shown, the end portion of the third restraining portion 433 located on the opposite side to the base end portion 427 of the third annular portion 440 passes through the inside of the distal end portion 428 of the third annular portion 440 .

[0197] In the third embodiment, the bundled body 410 further includes a 0th restraining portion 430 surrounding the entire circumference of the first bundled body W100. The 0th restraining portion 430 is directly connected to the first portion 421A at the base end portion 423 of the first annular portion 421, and is formed of a wire S extending from an end portion 423A of the first portion 421A constituting the base end portion 423 of the first annular portion 421. The 0th restraining portion 430 goes around the first bundled body W100 from the base end portion 423 of the first annular portion 421, returns to the base end portion 423 of the first annular portion 421, and is wound around the base end portion 423 of the first annular portion 421 at the return point.

[0198] In the third embodiment, one wire S is chain-braided in such a manner as to sequentially surround the second bundled body W200, the third bundled body W300, and the first bundled body W100, thereby forming the bundled body 10. In the third embodiment, the wire S is braided in such a manner that all loops formed by chain braiding surround the bundled body W, thereby forming the bundled body 10.

[0199] In the wire harness 400 according to the third embodiment configured as described above, the entire circumference of the second bundled body W200 is surrounded by the first annular portion 421 and the first restraining portion 431, and the entire circumference of the third bundled body W300 is surrounded by the second annular portion 422 and the second restraining portion 432, and the first annular portion 421 and the second annular portion 422 are connected to each other. Therefore, the second bundled body W200 and the third bundled body W300 can be restrained by using the common wire material S for forming the respective annular portions 421, 422 and the respective restraining portions 431, 432. Therefore, compared with the case where the second bundled body W200 and the third bundled body W300 are restrained individually, the time and labor for restraining can be reduced, and the restraining process can be accelerated. Furthermore, by connecting the second bundled body W200 and the third bundled body W300 around the branch portion W409, movement of one of them can be restricted, thereby preventing the bundling force of the wires in each bundled body W100, W200 from decreasing due to movement.

[0200] Furthermore, in the wire harness 400 according to the third embodiment, in addition to the second and third bundled bodies W200 and W300, the entire circumference of the first bundled body W100 is surrounded by the third annular portion 440 and the third restraining portion 433 formed of the wire material S, and the third annular portion 440 is connected to the first annular portion 421. Therefore, the time and labor for bundling the three bundled bodies W100, W200, and W300 can be reduced, and the bundling force of the electric wires in the three bundled bodies W100, W200, and W300 can be ensured.

[0201] In the wire harness 400 according to the third embodiment, the first restraining portion 431 is directly connected to the third portion 422A at the base end portion 425 of the second annular portion 422. Therefore, the wiring structure of the wire S at the base end portion 425 of the second annular portion 422 can be simplified. In addition, with this, the labor and time for restraining the bundled bodies W200 and W300 using the wire S can be reliably reduced.

[0202] Moreover, in the wiring harness 400 involved in the above-mentioned third embodiment, the first restraint portion 431 is directly connected to the second portion 421B, the second restraint portion 432 is directly connected to the fourth portion 422B and the fifth portion 440A, and the third restraint portion 433 is directly connected to the sixth portion 440B, thereby further simplifying the wiring structure of the wire S and further reducing the labor and time for using the wire S to restrain the bundled bodies W100, W200, and W300.

[0203] [Implementation Method 4]

[0204] Next, a wire harness 500 according to Embodiment 4 (fourth embodiment) of the present invention will be described. Fig. 20 4 is a side view showing a wire harness 500 according to the fourth embodiment. The fourth embodiment differs from the third embodiment in the structure of the connection portion between the annular portions 420, and the other structures are the same. In the following description of the fourth embodiment, the same reference numerals as those in the third embodiment are used for the same elements as those in the third embodiment, and the detailed description of the structure is omitted. Fig. 20 In the present invention, the same elements as those in the fourth embodiment are denoted by the same reference numerals as those in the third embodiment.

[0205] Similar to the third embodiment, the bundled body 510 of the wire harness 500 involved in the fourth embodiment has: a first annular portion 421 including a first portion 421A and a second portion 421B and arranged on the first circumferential surface W_A of the second bundled body W200; a second annular portion 422 including a third portion 422A and a fourth portion 422B and arranged on the first circumferential surface W_A of the third bundled body W300; and a third annular portion 440 including a fifth portion 440A and a sixth portion 440B and arranged on the first circumferential surface W_A of the first bundled body W100. In addition, similar to the third embodiment, the bundling body 510 of the wire harness 400 involved in the fourth embodiment has: a first restraint portion 431 extending from the base end portion 423 of the first annular portion 421 around the second circumferential surface W_B of the second bundled body W200 to the distal end portion 424; a second restraint portion 432 extending from the base end portion 425 of the second annular portion 422 around the second circumferential surface W_B of the third bundled body W300 to the distal end portion 426; and a third restraint portion 433 extending from the base end portion 427 of the third annular portion 440 around the second circumferential surface W_B of the first bundled body W100 to the distal end portion 428.

[0206] Similar to the third embodiment, in the wire harness 500 according to the fourth embodiment, the distal end portion 424 of the first annular portion 421 is connected to the proximal end portion 425 of the second annular portion 422, and the distal end portion 426 of the second annular portion 422 is connected to the proximal end portion 427 of the third annular portion 440. However, in the second embodiment, the bundled body 510 is provided with a connecting portion, and the proximal end portion of each annular portion 420 and the distal end portion of another annular portion 420 are connected by the connecting portion.

[0207] The distal end portion 424 of the first annular portion 421 is connected to the proximal end portion 425 of the second annular portion 422 via the first connecting portion 501. That is, the bundled body 510 includes the first connecting portion 501 connecting the distal end portion 424 of the first annular portion 421 and the proximal end portion 425 of the second annular portion 422. The distal end portion 426 of the second annular portion 422 is connected to the proximal end portion 427 of the third annular portion 440 via the second connecting portion 502. That is, the bundled body 510 includes the second connecting portion 502 connecting the distal end portion 426 of the second annular portion 422 and the proximal end portion 427 of the third annular portion 440. Here, the first connecting portion 501 described above corresponds to the "connecting portion" of the present invention.

[0208] The first connection portion 501 and the second connection portion 502 are formed by chain weaving the wire S in a state where the wire S does not surround the bundled body W. That is, in the fourth embodiment, the bundled body 510 is also formed by chain weaving one wire S in a manner of respectively surrounding the bundled bodies W100, W200, and W300, as in the third embodiment. However, in the fourth embodiment, the wire S is woven so that only one of the two continuous loops formed by chain weaving surrounds the bundled body W, and the other loop does not surround the bundled body W. Among them, the loops formed in a manner of not surrounding the bundled body W form the above-mentioned connection portions 501 and 502.

[0209] Specifically, the first connection portion 501 is roughly annular. The first connection portion 501 is formed by a wire S connecting the first constraint portion 31 and the third portion 22A, and is directly connected to the first constraint portion 431 and the third portion 422A, respectively. The first connection portion 501 passes through the distal end portion 424 of the first annular portion 421 in a state where both ends thereof are wound around the distal end portion 424 of the first annular portion 421. A gap is formed between the first connection portion 501 and the distal end portion 424 of the first annular portion 421. The end portion 425A of the third portion 422A and the end portion 425B of the fourth portion 422B constituting the base end portion 425 of the second annular portion 422 pass through the above-mentioned gap, and the first connection portion 501 is wound around the base end portion 425 of the second annular portion 422. Thus, the first connection portion 501 is wound around the distal end portion 424 of the first annular portion 421 and the proximal end portion 425 of the second annular portion 422 , thereby connecting the distal end portion 424 of the first annular portion 421 and the proximal end portion 425 of the second annular portion 422 .

[0210] The second connection portion 502 is substantially annular. The second connection portion 502 is formed by a wire S connecting the second constraint portion 432 and the fifth portion 440A, and is directly connected to the second constraint portion 432 and the fifth portion 440A, respectively. The second connection portion 502 passes through the distal end portion 426 of the second annular portion 422 in a state where both ends thereof are wound around the distal end portion 426 of the second annular portion 422. A gap is formed between the second connection portion 502 and the distal end portion 426 of the second annular portion 422. The end portion 427A of the fifth portion 440A and the end portion 427B of the sixth portion 440B constituting the base end portion 427 of the third annular portion 440 pass through the above-mentioned gap, and the second connection portion 502 is wound around the base end portion 427 of the third annular portion 440. Thus, the second connection portion 320 is wound around the distal end portion 426 of the second annular portion 422 and the proximal end portion 427 of the third annular portion 440 , thereby connecting the distal end portion 426 of the second annular portion 422 and the proximal end portion 427 of the third annular portion 440 .

[0211] Furthermore, in the fourth embodiment, unlike the third embodiment, at the distal end portion 428 of the third annular portion 440, a portion 503 of the wire S extending from the third constraint portion 433 is wound around the distal end portion 428 of the third annular portion 440 in the same manner as the first connecting portion 501. Specifically, at the distal end portion 428 of the third annular portion 440, the portion extending from the third constraint portion 433 is chain-woven, and a loop 503 is formed at the distal end portion 428 of the third annular portion 440 by the chain-woven.

[0212] In addition, in the fourth embodiment, at the base end portion 423 of the first annular portion 421, a portion 509 between the 0th constraint portion 430 and the first portion 421A in the wire S, that is, a portion 509 connecting them, is wound around the base end portion 423 of the first annular portion 421 in the same manner as the first connecting portion 501. Specifically, at the base end portion 423 of the first annular portion 421, the above-mentioned portion 509 is chain-woven, and a loop 509 is formed at the base end portion 423 of the first annular portion 421 by chain-weaving.

[0213] In the wire harness 500 according to the fourth embodiment, as in the third embodiment, the three bundled bodies W100, W200, and W300 can be bound using the common wire material S, thereby reducing the time and effort for binding and speeding up the binding process. In addition, it is possible to suppress the reduction in the binding force of the wires in each bundled body W100, W200, and W300 due to vibration.

[0214] In addition, in the wire harness 400 according to the fourth embodiment, the first connecting portion 501 connecting the distal end portion 424 of the first annular portion 421 and the proximal end portion 425 of the second annular portion 422 is formed by the wire S connecting the first restraining portion 431 and the third portion 422A, and their connecting structure is complicated. Therefore, it is possible to prevent the connection between the distal end portion 424 of the first annular portion 421 and the proximal end portion 425 of the second annular portion 422 from being easily released.

[0215] In the wire harness 400 according to the fourth embodiment, the first connection portion 501 is formed by connecting the first restraining portion 431 and the third portion 422A with the wire S, and is wound around the distal end portion 424 of the first annular portion 421 and the base end portion 425 of the second annular portion 422, thereby connecting them. Therefore, at the connection portion, the friction between the wires S can be increased, so that the movement of the wires S can be more strongly restricted.

[0216] In the wire harness 400 according to the fourth embodiment, the second connection portion 502 is formed by the wire S connecting the second constraint portion 432 and the fifth portion 440A, and is wound around the distal end portion 426 of the second annular portion 422 and the base end portion 427 of the third annular portion 440, so that they are connected. Therefore, at the connection portion, the friction between the wires S can be increased, so that the movement of the wires S can be more strongly restricted.

[0217] Furthermore, in the wire harness 400 according to the fourth embodiment, a portion 503 of the wire S extending from the third restraining portion 433 is wound around the distal end portion 428 of the third annular portion 440, and a portion 509 of the wire S between the 0th restraining portion 430 and the first portion 421A is wound around the base end portion 423 of the first annular portion 421. Therefore, the wire S can be prevented from being loosened at the distal end portion 428 of the third annular portion 440 and the base end portion 423 of the first annular portion 421.

[0218] [Modifications]

[0219] The embodiments of the present invention have been described above, but the above embodiments are merely examples for implementing the present invention. Therefore, the present invention is not limited to the above embodiments, and the above embodiments can be appropriately modified and implemented within the scope of the gist thereof.

[0220] For example, in the above-mentioned second embodiment, it is described that the distal end portion 24 of the first annular portion 21 and the base end portion 25 of the second annular portion 22 are connected via the first connecting portion 310, and the base end portion 23 of the first annular portion 21 and the distal end portion 26 of the second annular portion 22 are connected via the second connecting portion 320. However, one of the first connecting portion 310 and the second connecting portion 320 can be omitted, and the same structure as the first embodiment can be used to connect the distal end portion 24 of the first annular portion 21 and the base end portion 25 of the second annular portion 22, or to connect the base end portion 23 of the first annular portion 21 and the distal end portion 26 of the second annular portion 22.

[0221] Furthermore, in the second embodiment described above, the first connection portion 310 and the second connection portion 320 are each formed of one loop formed by chain knitting, but these connection portions 310 and 320 may be formed of two or more continuous loops.

[0222] In addition, in each of the above-mentioned embodiments, the case where each part and each restraint part constituting the annular portion are formed by a continuous single wire S is described, but a single wire formed by connecting a plurality of wires may be used as the wire S. In addition, a plurality of continuous wires may be tied in a chain-knitted state around the bundled body W, so that each part and each restraint part are formed by two wires.

[0223] The present invention can also be applied to a bundled body W that branches in three or more different directions from the end of the first bundled body W100. In this case, the structure of the bundled body 410 or 510 according to the third or fourth embodiment can be applied to other bundled bodies.

[0224] Fig.21 1 is a diagram showing a wire harness 700 in which the bundled body W includes a first bundled body W100, a second bundled body W200, a third bundled body W300, and a fourth bundled body W400 extending from the end of the first bundled body W100 in different directions. Fig.21 In the bundled body W of the third embodiment, compared with the bundled body W involved in the third embodiment, a fourth bundled body W400 is further branched from the first bundled body W100 between the third bundled body W300 and the first bundled body W100. Accordingly, the wire harness 700 is formed with a fourth inner corner portion 404 where the third bundled body W300 and the fourth bundled body W400 intersect, and a fifth inner corner portion 405 where the fourth bundled body W400 and the first bundled body W100 intersect. Fig.21 In the embodiment, the same elements as those in the third embodiment are denoted by the same reference numerals as those in the third embodiment. Fig.21 In the wire harness 700, the restraining structures of the bundling body 710 on the second and third bundled bodies W200 and W300 are applied to the fourth bundled body W400, and the connecting structure of the bundling body 710 on the second and third bundled bodies W200 and W300 is applied to the connecting structure of the third and fourth bundled bodies W300 and W400.

[0225] Specifically, Fig.21 The bundled body 710 of the wire harness 700 has, in addition to the first annular portion 421, the second annular portion 422, the first restraining portion 431, and the second restraining portion 432, a fourth annular portion 721 provided on the first circumferential surface W_A of the fourth bundled body W400 and extending from the fourth inner corner portion 404 to the fifth inner corner portion 405, and a fourth restraining portion 731 extending from the base end portion 723 of the fourth annular portion 721 around the second circumferential surface W_B of the fourth bundled body W400 to the distal end portion 724. In addition, the second annular portion 422 extends from the second inner corner portion 402 to the fourth inner corner portion 404. And, around the fourth inner corner portion 404, the distal end portion 426 of the second annular portion 422 and the fourth annular portion 721 are connected in the same manner as the first annular portion 421 and the second annular portion 422. That is, the base end portion 723 of the fourth annular portion 721 passes through the distal end portion 426 of the second annular portion 422 so that they are connected. Fig.21In the wire harness 700 , the third annular portion 440 is not connected to the second annular portion 422 but is connected to the distal end portion 724 of the fourth annular portion 721 .

[0226] In addition, in the third embodiment, the fourth embodiment and Fig.21 In the example of , the first annular portion 421 is described as extending from the first inner corner portion 401 to the second inner corner portion 402. However, in the case where the bundled body W is branched, the first annular portion only needs to extend in a direction intersecting the length direction of the second bundled body W200, and its extension direction is not limited to the above-mentioned direction. Similarly, the second annular portion only needs to extend in a direction intersecting the length direction of the third bundled body W300, and its extension direction is not limited to the above-mentioned direction.

[0227] For example, in Fig. 22 As shown in the wire harness 900, the bundled body W has Fig.21 In the case of the structure shown in FIG. 4 , the first annular portion 921 may extend from the first inner corner portion 401 to the fourth inner corner portion 404. In this case, the first restraining portion 931 is also configured to extend from the first inner corner portion 401 to the fourth inner corner portion 404. Fig. 22 In the present invention, the same elements as those in the third embodiment are denoted by the same reference numerals as those in the third embodiment.

[0228] exist Fig. 22 In the example of , the base end portion 425 of the second annular portion 422 is arranged near the fourth inner corner portion 404, and the distal end portion 426 is arranged near the second inner corner portion 402. In addition, around the fourth inner corner portion 404, the distal end portion 424 of the first annular portion 921 and the base end portion 425 of the second annular portion 422 are connected. In addition, the bundled body 910 is provided with a substantially annular fifth annular portion 951 which is arranged on the first peripheral surface W_A of the fourth bundled body W400 and extends from the second inner corner portion 402 to the fifth inner corner portion 405. And around the second inner corner portion 402, the base end portion 953 of the fifth annular portion 951 passes through the distal end portion 426 of the second annular portion 422, so that they are connected. Furthermore, the bundled body 910 is provided with a fifth restraining portion 955 extending from the base end portion 953 of the fifth annular portion 951 to the distal end portion 954 around the second peripheral surface W_B of the fourth bundled body W400 .

[0229] Furthermore, the bundled body to which the present invention is applied is not limited to the bundled body whose peripheral surface is covered with a resin member.

[0230] (Summary)

[0231] The above-mentioned embodiment and its modifications include the following disclosures.

[0232] One aspect of the present disclosure relates to a wire harness obtained by bundling a bundled body with a bundling body, the bundling body being formed of a flexible wire material, the bundled body including a plurality of electric wires, wherein the bundling body has a plurality of continuously formed annular portions arranged along a length direction of the bundled body, and adjacent annular portions are connected to each other, so that the bundled body is bundled.

[0233] According to the above configuration, the bundled body has a plurality of continuously formed annular portions, the plurality of annular portions are arranged along the longitudinal direction of the bundled body, and the adjacent annular portions are connected to each other, so that the bundled body is bundled.

[0234] Since the objects to be bundled are continuously bundled using the bundling body formed of flexible wire materials, the work of bundling the electric wires with the bundling body can be automated and accelerated.

[0235] Furthermore, since the objects to be bundled are bundled by connecting the adjacent annular portions to each other, the position of the bundled objects relative to the objects to be bundled is less likely to shift, and a decrease in the bundling force for bundling the electric wires can be suppressed.

[0236] In the above structure, it may also be that: the multiple annular portions include: a first annular portion formed by bending a portion of the wire; and a second annular portion formed by bending another portion of the wire, wherein the first annular portion and the second annular portion are repeatedly formed, and adjacent first annular portions and second annular portions are connected.

[0237] According to the above configuration, the first annular portion and the second annular portion are repeatedly formed, and the adjacent first annular portion and the adjacent second annular portion are connected.

[0238] Since the first annular portion and the second annular portion are repeatedly formed and connected to each other, the position of the bundling body relative to the bundled body is less likely to shift, and a decrease in the bundling force for bundling the electric wires can be suppressed.

[0239] In the above structure, the second annular portion may pass through the first annular portion, thereby connecting the first annular portion and the second annular portion, and the first annular portion may pass through the second annular portion, thereby connecting the second annular portion and the first annular portion.

[0240] According to the above configuration, the first annular portion and the second annular portion formed continuously are alternately passed through, so that the first annular portion and the second annular portion are connected.

[0241] Since the first annular portion and the second annular portion are connected by alternately passing through each other, the position of the bundling body relative to the body to be bundled is less likely to shift, and a decrease in the bundling force for bundling the electric wires can be suppressed.

[0242] In the above structure, the second annular portion may pass through the first annular portion so that the first annular portion and the second annular portion are connected, and the wire forms a first restraining portion between the first annular portion and the second annular portion, the first annular portion passes through the second annular portion so that the first annular portion and the second annular portion are connected, and the wire forms a second restraining portion between the second annular portion and the first annular portion, and the bundled body is bundled by the first restraining portion and the second restraining portion.

[0243] According to the above configuration, the body to be bundled is bundled by the first and second binding portions between the first and second annular portions that are continuously formed.

[0244] Since the first annular portion and the second annular portion are connected, the first restraining portion and the second restraining portion are less likely to loosen. Therefore, it is possible to suppress a decrease in the binding force of the electric wires.

[0245] As a specific structure of the above-mentioned structure, the following structure can be listed: the bundled body has: a first circumferential surface, which is one of the circumferential surfaces of the bundled body divided into two in the circumferential direction; and a second circumferential surface, which is located on the opposite side of the first circumferential surface, and the first annular portion and the second annular portion are respectively arranged on the first circumferential surface and are formed in a manner extending along the length direction of the bundled body, and the first annular portion includes: a first portion extending from an end portion located on one side in the length direction of the first annular portion, namely, a base end portion, to an end portion located on the other side, namely, a distal end portion; and a second portion, in the first annular portion, returning from the distal end portion to the base end portion, and the second annular portion includes: a third portion extending from an end portion located on one side in the length direction of the second annular portion, namely, a base end portion, to an end portion located on the other side, namely, a distal end portion; and a fourth portion, in the second annular portion, returning from the distal end portion to the base end portion.

[0246] In the above structure, the base end portion of the second annular portion is connected to the distal end portion of the first annular portion, the first annular portion is adjacent to the second annular portion on the one side in the length direction, the distal end portion of the second annular portion is connected to the base end portion of the first annular portion, and the first annular portion is adjacent to the second annular portion on the other side in the length direction, and the bundling body includes: a first restraining portion extending from the base end portion of the first annular portion around the second circumferential surface to the distal end portion of the first annular portion; and a second restraining portion extending from the base end portion of the second annular portion around the second circumferential surface to the distal end portion of the second annular portion.

[0247] According to the above configuration, the first annular portion and the first restraining portion, and the second annular portion and the second restraining portion can restrain the body to be bundled, and the electric wires can be reliably bundled.

[0248] Specifically, since the first annular portion and the first restraining portion are arranged so as to surround the peripheral surface of the bundled body, the electric wires can be bundled using the first annular portion and the first restraining portion.

[0249] Furthermore, since the second annular portion and the second restraining portion are arranged so as to surround the peripheral surface of the bundled body, the electric wires can be bundled using the second annular portion and the second restraining portion.

[0250] In the above structure, preferably, the first portion, the second portion, the third portion, the fourth portion, the first restraining portion, and the second restraining portion are formed by one continuous wire material.

[0251] According to this configuration, the bundled body including the electric wires can be easily bound using one continuous wire rod.

[0252] In the above configuration, preferably, in the circumferential direction of the bundled body, the lengths of the first restraining portion and the second restraining portion are longer than the lengths of the first annular portion and the second annular portion.

[0253] According to this configuration, the first restraining portion and the second restraining portion can reliably restrain the bundled body including the electric wires.

[0254] In the above configuration, preferably, the first restraint portion is directly connected to the third site at the base end portion of the second annular portion.

[0255] According to this configuration, the structure of the bundled body around the base end of the second annular portion can be simplified. In addition, with the simplification of the structure, the speed of the process of binding the bundled body using the wire can be reliably achieved.

[0256] In the above configuration, preferably, the second restraint portion is directly connected to the first site at the base end portion of the first annular portion.

[0257] According to this configuration, the structure of the bundled body around the base end of the first annular portion can be simplified. In addition, with the simplification of the structure, the speed of the process of binding the bundled body with the wire can be reliably achieved.

[0258] In the above structure, preferably, the bundling body includes: a first connecting portion, which is formed by the wire connecting the first restraining portion and the third portion, and connects the distal end portion of the first annular portion and the base end portion of the second annular portion, and the second annular portion is adjacent to the first annular portion on the other side in the longitudinal direction.

[0259] According to this structure, the connection structure between the distal end of the first annular portion and the base end of the second annular portion becomes complicated. Therefore, it is possible to prevent their connection from being easily released. In other words, in the case where the wire is damaged in the middle, it is possible to prevent the connection between the distal end of the first annular portion and the base end of the second annular portion from being released and the wire from being loosened.

[0260] In the above structure, preferably, the bundling body includes: a second connecting portion, which is formed by the wire connecting the second restraining portion and the first portion, and connects the distal end portion of the second annular portion and the base end portion of the first annular portion, and the first annular portion is adjacent to the second annular portion on the other side in the longitudinal direction.

[0261] According to this structure, the connection structure between the distal end of the second annular portion and the base end of the first annular portion becomes complicated. Therefore, it is possible to prevent their connection from being easily released. In other words, in the case where the wire is damaged in the middle, it is possible to prevent the connection between the distal end of the second annular portion and the base end of the first annular portion from being released and the wire from being loosened.

[0262] In the above configuration, preferably, a spacing distance between the base end portions of two adjacent first annular portions in the longitudinal direction is set to a size greater than 0 mm and not more than 18 mm.

[0263] According to this configuration, it is possible to prevent the performance of the wire harness from significantly changing due to temperature changes.

[0264] In the above configuration, preferably, the diameter of the virtual circle is set to a size of 8 mm or more and 20 mm or less, and when viewed in the longitudinal direction, the virtual circle passes through a point on the peripheral surface of the bundled body and surrounds the entire bundled body.

[0265] According to this configuration, it is also possible to prevent the performance of the wire harness from significantly changing due to temperature changes.

[0266] Here, when the peripheral surface of the bundled body is covered with a resin material, the flexibility of the bundled body changes greatly with temperature changes, and the performance of the wire harness tends to change greatly. Therefore, in the above structure, if a bundled body whose peripheral surface is covered with a resin material is used as the bundled body, it is possible to effectively prevent the performance of the wire harness from changing greatly with temperature changes.

[0267] The wire harness according to one aspect of the present disclosure is a wire harness obtained by bundling a bundled body with a bundling body, wherein the bundling body is formed of a flexible wire material, the bundled body includes a plurality of wires and is in a long strip shape, wherein the bundled body includes: a first bundled body extending in a specified direction; and a second bundled body and a third bundled body branching from an end of the first bundled body in two different directions, wherein the first bundled body, the second bundled body, and the third bundled body each have: a first peripheral surface, The first and second circumferential surfaces of the second bundled body are divided into two equal parts along the circumferential direction; and the second circumferential surface is located on the opposite side of the first circumferential surface, and the bundled body includes: a first annular portion, which is arranged on the first circumferential surface of the second bundled body and extends in a direction intersecting with the length direction of the second bundled body; a second annular portion, which is arranged on the first circumferential surface of the third bundled body and extends in a direction intersecting with the length direction of the third bundled body; a first restraining portion, which extends from the first circumferential surface of the third bundled body to the second circumferential surface of the third bundled body; The first annular portion includes an end portion, i.e., a base end portion, on one side of the first annular portion, extending around the second circumferential surface of the second body to be bundled to an end portion, i.e., a distal end portion, on the other side of the first annular portion; and a second restraining portion extending from an end portion, i.e., a base end portion, on one side of the second annular portion, around the second circumferential surface of the third body to be bundled to an end portion, i.e., a distal end portion, on the other side of the second annular portion, wherein the first annular portion includes: a first portion extending from the base end portion of the first annular portion to the distal end portion of the first annular portion; and a second portion returning from the distal end portion of the first annular portion to the base end portion of the first annular portion, and the second annular portion includes: a third portion extending from the base end portion of the second annular portion to the distal end portion of the second annular portion; and a fourth portion returning from the distal end portion of the second annular portion to the base end portion of the second annular portion, wherein the distal end portion of the first annular portion and the base end portion of the second annular portion are connected to each other.

[0268] According to this structure, the second and third bundled bodies can be constrained using the common wire material forming each annular portion and each constraining portion. Therefore, compared with the case where the second and third bundled bodies are constrained individually, the time and labor for constraining can be reduced, and the constraining process can be accelerated. In addition, since the movement of the second and third bundled bodies can be restricted by one of the other, the vibration of the second and third bundled bodies can be suppressed, and the reduction in the binding force of the wires included in each bundled body due to the vibration can be suppressed.

[0269] In the above configuration, preferably, the first restraint portion is directly connected to the third site at the base end portion of the second annular portion.

[0270] According to this configuration, the wiring structure of the wire at the base end portion of the second annular portion can be simplified, and the time and effort for restraining the second and third objects to be bundled using the wire can be reduced.

[0271] In the above configuration, preferably, the bundled body includes a connecting portion formed of the wire connecting the first restraining portion and the third portion and connecting the distal end portion of the first annular portion and the proximal end portion of the second annular portion.

[0272] According to this configuration, since the connection structure between the distal end portion of the first annular portion and the proximal end portion of the second annular portion becomes complicated, it is possible to prevent the connection therebetween from being easily released.

[0273] One aspect of the present disclosure relates to a wire harness bundling method for forming a wire harness by bundling a bundled body with a bundling body, wherein the bundling body is formed of a flexible wire material, and the bundled body includes a plurality of wires. The wire harness bundling method includes: a connecting step of forming a plurality of ring-shaped portions along a length direction of the bundled body and connecting the plurality of ring-shaped portions to each other.

[0274] According to the above configuration, the objects to be bundled are continuously bundled using the bundling body formed of flexible wires by the connecting step of connecting the plurality of annular portions to each other along the longitudinal direction of the objects to be bundled. Therefore, the operation of bundling the wires with the bundling body can be automated and accelerated.

[0275] One aspect of the present disclosure relates to a wire harness bundling processing device that forms a wire harness by bundling a bundled body with a bundling body, the bundling body being formed of a flexible wire, the bundled body including a plurality of wires, the wire harness bundling processing device comprising: a wire supply unit that supplies the wire near the bundled body; and a ring forming unit that bends a portion of the wire supplied from the wire supply unit to form a ring portion, wherein the ring forming unit continuously forms a plurality of ring portions with respect to the wire supplied from the wire supply unit, arranges the plurality of ring portions along the length direction of the bundled body, and connects the ring portions adjacent to each other along the length direction of the bundled body, thereby forming the bundled body.

[0276] According to the above configuration, the loop forming unit continuously forms a plurality of loops on the wire supplied from the wire supply unit, arranges the plurality of loops along the longitudinal direction of the bundled body, and connects the loops adjacent to each other along the longitudinal direction of the bundled body to form the bundled body.

[0277] Since the objects to be bundled are continuously bundled by the bundling body formed of flexible wire materials, the work of bundling the electric wires with the bundling body can be automated and accelerated.

[0278] Furthermore, since the objects to be bundled are bundled by connecting the adjacent annular portions to each other, the position of the bundled objects relative to the objects to be bundled is less likely to shift, and a decrease in the bundling force for bundling the electric wires can be suppressed.

[0279] In the above structure, it can also be that: the ring-forming portion bends a part of the wire to form a first ring-shaped portion, bends another part of the wire to form a second ring-shaped portion, and repeatedly forms the first ring-shaped portion and the second ring-shaped portion, and the plurality of ring-shaped portions are connected to each other by connecting adjacent first ring-shaped portions and second ring-shaped portions.

[0280] According to the above configuration, the plurality of annular portions are connected to each other by connecting the adjacent first annular portion and the second annular portion.

[0281] Since the first annular portion and the second annular portion are repeatedly formed and connected, the operation of bundling the electric wires with the bundling body can be accelerated.

[0282] In the above structure, the annular forming portion may connect the first annular portion and the second annular portion by allowing the second annular portion to pass through the first annular portion, and connect the second annular portion and the second annular portion by allowing the first annular portion to pass through the second annular portion.

[0283] According to the above configuration, the first annular portion and the second annular portion formed continuously are alternately passed through, so that the first annular portion and the second annular portion are connected.

[0284] Since the first annular portion and the second annular portion are repeatedly formed and connected by alternately passing them, the operation of bundling the electric wires with the bundling body can be accelerated.

[0285] In the above structure, it can also be that: the annular portion forming body pulls out a part of the wire material in a manner of passing through the first annular portion formed on the wire material, thereby forming the second annular portion connected to the first annular portion, and pulls out a part of the wire material in a manner of passing through the second annular portion formed on the wire material, thereby forming the first annular portion connected to the second annular portion.

[0286] According to the above configuration, the annular portion forming body forms the next annular portion by pulling out a portion of the wire material so as to pass through the first annular portion or the second annular portion formed on the wire material, and connects the next annular portion to the first annular portion or the second annular portion.

[0287] Therefore, the plurality of annular portions can be connected to each other without complicating the operation of the annular portion forming body.

[0288] In the above structure, it can also be that: the direction intersecting the length direction of the bundled body is set as the first direction, and the direction intersecting the length direction of the bundled body and the first direction is set as the second direction, and the ring-shaped forming part and the wire feeding part are constructed so that: each time they reciprocate once in the first direction, they move a specified distance in the length direction of the bundled body, and form the second ring-shaped part connected to the first ring-shaped part on one side of the bundled body in the first direction, and form the first ring-shaped part connected to the second ring-shaped part on the other side of the bundled body in the first direction, and the ring-shaped forming part passes through the one side of the bundled body in the second direction to reciprocate in the first direction, and the wire feeding part passes through the other side of the bundled body in the second direction to reciprocate in the first direction.

[0289] In addition, the above-mentioned "first direction which is a direction intersecting with the longitudinal direction of the to-be-bound body" corresponds to the X-axis direction in the above-mentioned embodiment.

[0290] According to the above configuration, the loop forming portion and the wire feeding portion move together relative to the bundled body, and the bundled body is bundled by arranging the plurality of loop portions around the bundled body and connecting adjacent loop portions.

[0291] Therefore, the objects to be bundled can be bundled without complicating the operations of the loop forming portion and the wire feeding portion.

[0292] In the above configuration, the loop forming portion and the wire material supplying portion may be capable of changing a moving distance in the longitudinal direction of the bundled body each time the bundled body moves back and forth once in the first direction.

[0293] According to the above configuration, by changing the movement distance of the objects to be bundled in the longitudinal direction by the loop forming portion and the wire feeding portion, the interval between the objects to be bundled by the first loop portion and the second loop portion can be changed, thereby appropriately bundling the objects to be bundled.
