Description

[Technical field]

[0001] The present invention relates to a tape end application device that applies an end portion of a tape to the peripheral surface of a linear object to be tape-applied, such as a bundle of electric wires. [Background technology]

[0002] Conventionally, in the manufacture of wire harnesses for automobiles and the like, a device that wraps tape around the peripheral surface of a linear object to which the tape is to be applied, such as a bundle of electric wires, has been used (see, for example, Patent Document 1). In the device described in Patent Document 1, a process is performed in which an end portion of the pulled-out tape is applied to the peripheral surface prior to winding the tape around the peripheral surface of the object to which the tape is to be applied. For this process, a tape end application device is provided that applies the tape by pressing the end portion of the tape against the peripheral surface of the object to which the tape is to be applied with a rotating roller.

[0003] [Patent Document 1] JP 2015-224123 A Summary of the Invention [Problem to be solved by the invention]

[0004] Here, in the above-mentioned tape terminal joining device, the rotating roller joins the end of the tape so as to go over the tape joining target in the circumferential direction. Due to this configuration, if the rotating roller is not set above the center of the tape joining target, it will not be able to go over the tape joining target, and the tape joining area tends to be limited. In addition, in the above-mentioned tape terminal joining device, when tape is joined to tape joining targets with different outer diameters, it is necessary to set the position of the rotating roller so that it can go over the tape joining target with the largest expected outer diameter. As a result, for tape joining targets with small outer diameters, the distance from the rotating roller to the circumferential surface becomes long, and there is a possibility that joining the tape itself will be difficult in the first place.

[0005] Therefore, the present invention focuses on the above-mentioned problems and aims to provide a tape terminal application device that can apply a tape terminal portion with a sufficient application area to multiple types of tape application objects having different outer diameters. [Means for solving the problem]

[0006] In order to solve the above problem, the tape terminal application device is characterized by comprising a band portion formed in a strip shape from a deformable flexible material, a band holding portion which holds the band portion so that its peripheral surface extends in a cross direction relative to a linear tape application object to which the tape is applied, and a band drive portion which drives the band holding portion so that the band, whose midportion away from the tip intersects with the tape application object, is pressed against the peripheral surface of the tape application object by the band portion, thereby applying an terminal portion of the tape closer to the tip than the midportion to the peripheral surface. Effect of the Invention

[0007] According to the above electric wire transport device, it is possible to apply a tape to the end portions of a plurality of types of tape application objects having different outer diameters, with a sufficient application area. [Brief description of the drawings]

[0009] An embodiment of a tape terminal joining device will be described below.

[0010] FIG. 1 is a schematic diagram showing a tape terminal joining device according to one embodiment.

[0011] The tape terminal joining device 1 of this embodiment is used in the manufacture of wire harnesses for automobiles and the like, prior to spirally winding the tape T1 pulled out from a tape reel T2 onto a bundle of electric wires W1 as a linear tape joining target for the purpose of protecting the circumferential surface, etc. The tape terminal joining device 1 joins an end portion T13 closer to the leading end than a middle portion T12 away from the leading end T11 onto the circumferential surface W11 of the bundle of electric wires W1 prior to the winding process of the tape T1. The winding process to be performed thereafter is performed with the end portion T13 joined to the circumferential surface W11 as the starting point of winding. The tape terminal joining device 1 includes a band unit 11, a band holding unit 12, and a band driving unit 13.

[0012] The band portion 11 is a member formed in a band shape from a deformable flexible material, specifically, a stretchable member formed in a band shape from rubber as an elastic material. In this embodiment, a plurality of band portions 11, specifically, three band portions 11 are provided.

[0013] The band holding portion 12 is a member that holds the band portion 11 so as to extend in a direction D11 intersecting the electric wire bundle W1, and includes a frame portion 121 and an arm portion 122.

[0014] The frame portion 121 is a member that holds both ends of the band portion 11 and has a shape that avoids the electric wire bundle W1 when the band portion 11 presses the tape T1 against the peripheral surface W11 of the electric wire bundle W1. The frame portion 121 includes a frame main body 121a and a pair of holding bars 121b. The frame main body 121a is a member that has a substantially C-shaped arch shape that avoids the electric wire bundle W1 by extending in a cross direction D11 with the electric wire bundle W1 housed inside. The pair of holding bars 121b are bar members that protrude along the electric wire bundle W1 from both ends of the arch shape of the frame main body 121a. The three band portions 11 are attached to the frame portion 121 in a state of being arranged in the width direction D12 of the tape T1 so as to be stretched between the pair of holding bars 121b.

[0015] The arm portion 122 is a portion that holds the end portion of the frame portion 121 on the side remote from the electric wire bundle W1 so as to be rotatable about a rotation axis 122a along the electric wire bundle W1.

[0016] The band driving unit 13 drives the band holding unit 12 so as to press the tape T1, which is arranged so that the middle portion T12 intersects with the electric wire bundle W1, against the peripheral surface W11 of the electric wire bundle W1 with the band portion 11. By driving the band holding unit 12 in this manner, the band driving unit 13 attaches the end portion T13 of the tape T1 closer to the tip T11 than the middle portion T12 to the peripheral surface W11 of the electric wire bundle W1. The band driving unit 13 includes a linear driving unit 131 and a rotation driving unit 132.

[0017] The linear drive unit 131 is a part that linearly drives the arm unit 122 of the band holding unit 12 in a direction D13 toward or away from the electric wire bundle W1. By such linear drive, the linear drive unit 131 brings the frame unit 121, i.e., the band unit 11, closer to the electric wire bundle W1 via the arm unit 122 when applying the tape T1.

[0018] The rotation drive unit 132 is a part that rotates the frame unit 121 connected to the arm unit 122 via the rotation shaft 122a around the rotation shaft 122a. When applying the tape T1, the rotation drive unit 132 presses the band unit 11 against the circumferential surface W11 of the wire bundle W1 via the frame unit 121. Here, in this embodiment, the rotation drive unit 132 is a cylinder mechanism that rotates the frame unit 121 around the rotation shaft 122a by linearly pressing a predetermined connection point 121c of the frame unit 121 with the tip of the piston 132a. The tip of the piston 132a is connected to the frame main body 121a of the frame unit 121 so as to be rotatable around a piston end rotation shaft 132b provided parallel to the rotation shaft 122a.

[0019] In the band drive unit 13, in the initial stage of applying the tape T1, the rotation drive unit 132 rotates the frame portion 121 in a direction away from the peripheral surface W11 and raises it up. Then, in the band drive unit 13, with the frame portion 121 raised up, the linear drive unit 131 moves the frame portion 121 closer to the electric wire bundle W1 via the arm portion 122 until a part of the band portion 11 comes into contact with the tape T1. Thereafter, in the band drive unit 13, the rotation drive unit 132 rotates the frame portion 121 in a direction closer to the peripheral surface W11 until the band portion 11 is bent along the peripheral surface W11 while sandwiching the tape T1 between the frame portion 121 and the peripheral surface W11.

[0020] Next, a series of operations from when the tape T1 is pulled out in the tape winding device 2 equipped with the tape terminal joining device 1 described above until the end portion T13 is joined to the electric wire bundle W1 will be described below.

[0021] Fig. 2 is a diagram showing how the tape is pulled out and the middle part of the tape is arranged so as to contact the peripheral surface of the bundle of electric wires in the tape winding device equipped with the tape terminal joining device shown in Fig. 1. Fig. 3 is a schematic diagram showing a simplified characteristic part of the series of operations shown in Fig. 2.

[0022] 2 and 3, the tape T1 is pulled out from the tape reel T2 set in the tape winding device 2. The tape T1 is pulled out by gripping the leading end T11 of the tape T1 with the short tape gripping mechanism 21 and pulling out the tape T1 in a pulling direction D14 intersecting with the electric wire bundle W1. At the stage of this first step S11, the tape T1 is separated from the electric wire bundle W1, and the tape terminal joining device 1 is disposed at a position separated from the tape T1. Furthermore, in the tape terminal joining device 1, the rotation drive unit 132 of the band drive unit 13 has raised the band portion 11 via the frame portion 121.

[0023] In the second step S12 following the first step S11, the tape T1 is brought closer to the electric wire bundle W1 together with the tape winding device 2 in the first approach direction D15. This causes the middle portion T12 of the tape T1 to be pressed against the peripheral surface W11 of the electric wire bundle W1. At this time, the tape terminal attachment device 1 in the band pulled-up state is also brought closer to the electric wire bundle W1 together with the tape T1 as described above, but at the stage of the second step S12, the relative distance between the tape terminal attachment device 1 and the tape T1 does not change.

[0024] Fig. 4 is a diagram showing how the band portion of the tape terminal joining device approaches and contacts the tape whose intermediate portion is pressed against the peripheral surface of the electric wire bundle in the second step of Fig. 2 and Fig. 3. Fig. 5 is a schematic diagram showing a simplified characteristic portion of the series of operations shown in Fig. 4.

[0025] 2 and 3, in a third step S13, the short tape gripping mechanism 21 in the tape winding device 2 releases the leading end T11 of the tape T1. At the same time, in the tape terminal joining device 1, the band part 11 starts moving in a second approaching direction D16 toward the tape T1 while being pulled up by the rotation drive part 132. This movement of the band part 11 is performed by the linear drive part 131 moving the frame part 121, i.e., the band part 11, via the arm part 122 in the second approaching direction D16 along the approaching / separating direction D13 with respect to the electric wire bundle W1.

[0026] In a fourth step S14 following the third step S13, in the tape terminal joining device 1, the linear drive unit 131 moves the band portion 11 in the second approaching direction D16 until a part of the band portion 11 comes into contact with the tape T1. At the stage of this fourth step S14, in the tape winding device 2, the terminal portion T13 of the tape T1, whose leading end T11 is released, is pushed by the band portion 11 and bent toward the peripheral surface W11 of the electric wire bundle W1.

[0027] Fig. 6 is a diagram showing how the band part of the tape terminal joining device presses and joins the end part of the tape bent onto the circumferential surface of the bundle of electric wires in the fourth step of Fig. 4 and Fig. 5. Fig. 7 is a schematic diagram showing a simplified characteristic part of the operation shown in Fig. 6.

[0028] 4 and 5, in the tape terminal joining device 1, the movement of the band portion 11 by the linear drive unit 131 is stopped at a stage where the terminal portion T13 of the tape T1 is sufficiently bent toward the peripheral surface W11 of the electric wire bundle W1. After that, the rotation drive unit 132 pushes out the frame portion 121 in the pushing direction D17 by the piston 132a. This pushing causes the frame portion 121, i.e., the band portion 11, to rotate about the rotation axis 122a in the tape joining direction D18, and the terminal portion T13 of the tape T1 in the bent state as described above is pressed against the peripheral surface W11 of the electric wire bundle W1 to join it. At this time, the band portion 11 stretches, deforms, and bends along the shape of the peripheral surface W11 with the tape T1 sandwiched between it and the peripheral surface W11 of the wire bundle W1, and the restoring force against the bending presses the end portion T13 of the tape T1 firmly against the peripheral surface W11 to adhere it.

[0029] This fifth step S15 completes the joining of the end portion T13 of the tape T1 by the tape terminal joining device 1. Thereafter, in the tape terminal joining device 1, the operations of the third step S13 to the fifth step S15 described above are performed in reverse, and the band portion 11 is separated from the electric wire bundle W11 to which the tape terminal has been joined and returned to the initial position.

[0030] According to the tape terminal joining device 1 of the embodiment described above, joining of the terminal portion T13 of the tape T1 to the peripheral surface W11 of the electric wire bundle W1 is performed by pressing the tape T1 with the band portion 11 formed in a strip shape from a deformable flexible material. The band portion 11 flexibly deforms to fit the shape of the peripheral surface W11 according to the outer diameter of the electric wire bundle W1 while pressing the tape T1 against the peripheral surface W11 of the electric wire bundle W1, so that the terminal portion T13 of the tape T1 is joined to the electric wire bundle W1 with a sufficient joining area. In other words, according to this embodiment, the terminal portion T13 of the tape T1 can be joined to a plurality of types of electric wire bundles W1 having different outer diameters with a sufficient joining area.

[0031] Here, in this embodiment, the band holding unit 12 includes a frame unit 121 that holds both ends of the band unit 11 and has a shape that avoids the electric wire bundle W1, and an arm unit 122 that holds the end of the frame unit 121 rotatably around a rotation axis 122a. The band driving unit 13 includes a linear driving unit 131 that linearly drives the arm unit 122, and a rotation driving unit 132 that rotates the frame unit 121 around the rotation axis 122a to press the band unit 11 against the circumferential surface W11 of the electric wire bundle W1. According to this configuration, the linear driving unit 131 moves the band unit 11 closer to the electric wire bundle W1, while the rotation driving unit 132 rotates the band unit 11 toward the circumferential surface W11, so that the band unit 11 can attach the end portion T13 of the tape T1 with the minimum necessary movement.

[0032] In this embodiment, the rotation drive unit 132 is a cylinder mechanism. With this configuration, by controlling the amount of extrusion of the piston 132a in the cylinder mechanism, the amount of rotation of the band portion 11 can be effectively controlled via the frame portion 121 so that the band portion 11 is deformed to sufficiently conform to the shape of the circumferential surface W11 of the electric wire bundle W1. Furthermore, by employing the cylinder mechanism, such control can be performed at a lower cost than, for example, a rotation drive structure using a servo motor.

[0033] In the present embodiment, the band drive unit 13 first moves the frame unit 121 up, and then the linear drive unit 131 moves the frame unit 121 closer to the electric wire bundle W1 until a part of the band unit 11 comes into contact with the tape T1. Then, the rotation drive unit 132 rotates the frame unit 121 until the band unit 11 is bent along the circumferential surface W11 while sandwiching the tape T1 between the frame unit 121 and the circumferential surface W11. With this configuration, the frame unit 121, i.e., the band unit 11, is brought sufficiently close to the electric wire bundle W1 while suppressing interference with the electric wire bundle W1, and the band unit 11 can be sufficiently bent and pressed against the circumferential surface W11 of the electric wire bundle W1 by the subsequent rotation drive.

[0034] In this embodiment, the frame portion 121 includes an arch-shaped frame main body 121a and a pair of holding bars 121b protruding from both ends thereof, and the band portion 11 is attached so as to be hung between the pair of holding bars 121b. With this configuration, the arch shape of the frame main body 121a effectively avoids the electric wire bundle W1, and the band portion 11 hung between the holding bars 121b at both ends can be sufficiently pressed against the peripheral surface W11 of the electric wire bundle W1.

[0035] In this embodiment, the band holding portion 12 holds a plurality of band portions 11 (three in this embodiment) so as to be aligned in the width direction D12 of the tape T1. With this configuration, the plurality of band portions 11 can effectively press and attach a plurality of types of tapes T1 having different tape widths to the peripheral surface W11 of the electric wire bundle W1.

[0036] In this embodiment, the band portion 11 is an elastic member made of rubber as an elastic material. This configuration allows the band portion 11 to be more flexibly deformed to fit the shape of the circumferential surface W11 of the wire bundle W1. The deformation of the band portion 11 during tape application is accompanied by the extension of the rubber band portion 11, so that the restoring force against the extension allows the end portion T13 of the tape T1 to be strongly pressed against the circumferential surface W11 for application.

[0037] The embodiment described above is merely a representative example of the tape terminal joining device, and the tape terminal joining device is not limited to this embodiment, but may be modified in various ways.

[0038] For example, in the above-described embodiment, a tape terminal application device 1 that applies an end portion T13 of a tape T1 to a bundle of electric wires W1 for a wire harness for an automobile is exemplified as an example of a tape terminal application device. However, the tape terminal application device is not limited to this. The tape terminal application device may apply an end portion of a tape to the peripheral surface of a linear tape application target, for example, a tape terminal application device that applies an end portion of a tape to the peripheral surface of an exterior material such as a corrugated tube in a wire harness. In other words, the specific form of the tape application target is not important.

[0039] In the above embodiment, the tape terminal joining device 1 is exemplified as an example of a tape terminal joining device, which joins the terminal portion T13 of the tape T1 pulled out from the tape reel T2 set in the tape winding device 2 to the circumferential surface W11 of the electric wire bundle W1. However, the tape terminal joining device is not limited to this. As long as the tape terminal joining device joins the terminal portion of the tape arranged so that the midway portion away from the leading end intersects with the tape joining target to the circumferential surface of the tape joining target, the tape may be used for a purpose other than winding. In addition, the tape is not limited to the tape pulled out from the tape reel set in the tape winding device, and may be cut into a strip and arranged so as to intersect with the tape joining target. In other words, the tape used is not limited to a specific form.

[0040] In the above-described embodiment, the band holding unit 12 having the frame portion 121 and the arm portion 122, and the band drive unit 13 having the linear drive unit 131 and the rotation drive unit 132 are exemplified as examples of the band holding unit and the band drive unit, respectively. However, the band holding unit and the band drive unit are not limited to these. The band holding unit does not require a specific holding structure for the band unit, and the band drive unit does not require a specific drive structure for the band holding unit. However, as described above, by linearly driving the arm portion 122 of the band holding unit 12 by the linear drive unit 131 of the band drive unit 13 and rotationally driving the frame portion 121 by the rotation drive unit 132, the end portion T13 of the tape T1 can be attached with the minimum necessary movement.

[0041] In the above-described embodiment, the rotation drive unit 132 serving as a cylinder mechanism is exemplified as an example of the rotation drive unit. However, the rotation drive unit is not limited to this and may be a mechanism using a motor, and the specific mechanism is not important. However, as described above, by employing a cylinder mechanism as the rotation drive unit 132, the amount of rotation of the band portion 11 can be effectively and inexpensively controlled.

[0042] In the above-described embodiment, the band drive unit 13 is exemplified as an example of the band drive unit in which the linear drive unit 131 performs linear drive when the frame unit 121 is pulled up, and then the rotation drive unit 132 performs rotation drive. However, the band drive unit is not limited to this, and even if a linear drive unit and a rotation drive unit are provided, the specific drive mode of each drive unit is not limited. However, as described above, according to the drive mode of linear drive when the frame unit 121 is pulled up and then rotation drive, the band unit 11 can be brought sufficiently close to the electric wire bundle W1, and then the band unit 11 can be sufficiently bent and pressed against the peripheral surface W11.

[0043] In the above-described embodiment, the frame 121 is exemplified as an example of the frame, in which the band 11 is hung across a pair of holding bars 121b provided on the arch-shaped frame main body 121a. However, the frame is not limited to this, and the specific shape and the holding manner of the band are not limited as long as the frame has a shape that avoids the target to which the tape is attached. However, as described above, the frame 121 having the arch-shaped frame main body 121a and the pair of holding bars 121b across which the band 11 is hung can sufficiently press the band 11 while effectively avoiding the electric wire bundle W1.

[0044] Furthermore, in the above-described embodiment, the band holding portion 12 that holds a plurality of band portions 11 (specifically, three band portions) is exemplified as an example of the band holding portion. However, the band holding portion is not limited to this, and the number of band portions that can be held may be one. However, as described above, by holding a plurality of band portions 11 with the band holding portion 12, it is possible to effectively press and attach a plurality of types of tape T1 having different tape widths. Note that even when a plurality of band portions are provided, the number is not limited to three, and any number can be set.

[0045] In the above-described embodiment, the band portion is an elastic band portion 11 made of an elastic material (specifically, rubber) and is exemplified as an example of the band portion. However, the band portion is not limited to this, and may be, for example, a cloth band or a flexible plastic band, etc., as long as it is formed in a strip shape from a deformable flexible material, and any material may be used. However, as described above, the elastic band portion 11 made of an elastic material can be deformed more flexibly, and the end portion T13 of the tape T1 can be strongly pressed and attached by the restoring force against the extension. Note that even when the band portion is made of an elastic material, the elastic material is not limited to rubber, and may be an elastic resin material, etc. [Explanation of symbols]
