[0008] 1. Technical issues to be resolved

[0009] In the processing of a multi-core shielded cable in which a drain wire and a plurality of core wires are covered with a sheath, each wire is processed separately in a front end processing step such as crimping terminals to the drain wire and the core wire. Therefore, it is preferable to identify the drain wire and the core wire separately before the front end processing step. The processing of the drain wire and the processing of the core wire are different in many cases, so it is necessary to at least distinguish and identify the drain wire and the core wire.

[0010] The present invention is completed in view of this point, and its purpose is to provide a processing device for a multi-core shielded cable, which is configured to distinguish between noise-reducing wires and core wires before processing the front end portion, thereby achieving high efficiency as a device.

[0011] (II) Technical solution

[0012] The processing device for a multi-core shielded cable of the present invention includes: a pre-process device that at least peels the sheath of a multi-core shielded cable having a drain wire, one or more core wires, and a sheath covering the drain wire and the core wires; a detection device that detects the position of the drain wire in the circumferential direction of the multi-core shielded cable; a post-process device that is arranged in line with the pre-process device in a specified conveying direction and processes at least a part of the front ends of the drain wire and the core wires; a positioning device; a transfer device that receives the multi-core shielded cable from the pre-process device and transfers it to the post-process device; and a control device. The positioning device includes: a first gripping device that grips the multi-core shielded cable such that the length direction is aligned with an orthogonal direction orthogonal to the conveying direction; and a first rotating device that rotates the multi-core shielded cable gripped by the first gripping device around a first rotation axis extending along the orthogonal direction. The control device controls the positioning device based on the detection result of the detection device, and at least drives the first rotating device so that the drain wire moves to a predetermined position around the first rotation axis.

[0013] According to the above processing device for a multi-core shielded cable, the multi-core shielded cable rotates in such a way that the drain wire moves to a predetermined position. Based on the position of the moved drain wire, the drain wire and the core wires can be distinguished. For example, in a process performed by the post-process device such as peeling or crimping, sometimes the processing conditions are divided according to the drain wire and the core wires. By distinguishing the drain wire and the core wires, the setting of the processing conditions becomes easy. Thus, the processing device for the multi-core shielded cable can be made more efficient.

[0014] According to a preferred mode of the processing device for a multi-core shielded cable of the present invention, the first rotating device rotates the multi-core shielded cable so that the drain wire moves to the most upstream or the most downstream in the conveying direction among the drain wire and the core wires.

[0015] According to the above processing device for a multi-core shielded cable, the drain wire is located at the end in the conveying direction in the post-process device, so that the processing of the drain wire is the first or the last in the processing of the drain wire and the core wires. Therefore, when the processing of the drain wire is different from the processing of the core wires, the number of changeover adjustments (in Japanese: 段取り変更) can be minimized.

[0016] According to a preferred embodiment of the processing device for a multi-core shielded cable of the present invention, the positioning device comprises: a second holding device, which is arranged on the pre-processing device and holds the multi-core shielded cable in a manner that the length direction is consistent with the orthogonal direction; and a second rotating device, which rotates the multi-core shielded cable held by the second holding device around a second rotating axis extending along the orthogonal direction. The detection device is configured to detect the position of the drain wire in the circumferential direction of the multi-core shielded cable when the multi-core shielded cable is held by the second holding device. The control device controls the second rotating device to rotate the multi-core shielded cable based on the detection of the detection device so that the drain wire faces the detection device, and then controls the first rotating device to move the drain wire to the predetermined position.

[0017] According to the processing device of the multi-core shielded cable described above, the circumferential position of the drain wire in the multi-core shielded cable when the drain wire is held by the second holding device of the previous process processing device (hereinafter, also referred to as the circumferential position of the drain wire) is detected by a detection device, so that the circumferential position of the drain wire is made to face the detection device. Thus, the circumferential position of the drain wire is determined, and the processing of the drain wire and the core wire in the previous process processing device becomes easy. In addition, in the previous process processing device, the circumferential position of the drain wire is made to face the detection device, so that the alignment of the drain wire can be accurate. Since the alignment of the drain wire in the previous process processing device can be accurately performed, the alignment of the drain wire based on the first holding device and the first rotating device can also be performed more accurately.

[0018] According to a preferred embodiment of the above-mentioned multi-core shielded cable processing device, the pre-processing device includes a tube installation device, and the tube installation device installs a heat shrink tube on the noise drain wire moving toward the detection device.

[0019] According to the above-mentioned processing device for the multi-core shielded cable, since the circumferential position of the noise-reducing wire is determined by the action of the second rotating device, the heat shrink tube can be easily installed.

[0020] According to a preferred embodiment of the processing device of the multi-core shielded cable of the present invention, the pre-process processing device is provided with a bending device, which bends the multi-core shielded cable into a U-shape in such a manner that both ends are arranged in the conveying direction. The bending device forms on the multi-core shielded cable: an upstream side portion, which extends along the orthogonal direction; a downstream side portion, which is downstream of the upstream side portion in the conveying direction and extends along the orthogonal direction; and a bending portion, which bends between the upstream side portion and the downstream side portion. The detection device detects the position of the drain wire on the upstream side in the circumferential direction of the upstream side portion and the position of the drain wire on the downstream side in the circumferential direction of the downstream side portion. The first holding device is configured to hold the upstream side portion of the multi-core shielded cable. The first rotating device is configured to rotate the upstream side portion of the multi-core shielded cable. The positioning device comprises: a first downstream holding device, which is arranged on the downstream side of the conveying direction relative to the first holding device and holds the downstream side portion of the multi-core shielded cable; and a first downstream rotating device, which rotates the downstream side portion held by the first downstream holding device around another first rotating axis extending in the orthogonal direction. The control device controls the first downstream rotating device to move the downstream side drain wire to a predetermined position around the other first rotating axis.

[0021] According to the processing device of the multi-core shielded cable, the position of the drain wire can be determined at both ends of the multi-core shielded cable bent into a U shape for sequential processing. Therefore, the drain wire and the core wire can be distinguished at both ends of the multi-core shielded cable.

[0022] According to a preferred embodiment of the processing device for the multi-core shielded cable, the first rotating axis is arranged to be offset from a line through which the axis of the upstream portion passes when the first holding device holds the upstream portion of the multi-core shielded cable. The first rotating device is configured to rotate the first holding device around the first rotating axis so that the line through which the axis of the upstream portion passes moves toward the downstream side of the conveying direction.

[0023] According to the processing device for the multi-core shielded cable, both ends of the multi-core shielded cable are brought closer together in the conveying direction, and the distance between the two ends is narrowed, so that the length of the post-processing device in the conveying direction can be shortened.

[0024] According to a preferred embodiment of the processing device for the multi-core shielded cable, the other first rotation axis is arranged to be offset from a line passing through the axis of the downstream portion when the downstream first holding device holds the downstream portion of the multi-core shielded cable. The downstream first rotation device is configured to rotate the downstream first holding device around the other first rotation axis so that the line passing through the axis of the downstream portion moves toward the upstream side of the conveying direction.

[0025] According to the processing device for the multi-core shielded cable, both ends of the multi-core shielded cable are similarly brought closer in the conveying direction, and the distance between the two ends is narrowed, so that the length of the post-processing device in the conveying direction can be shortened.

[0026] The processing device of a multi-core shielded cable in a preferred embodiment of the present invention further comprises: an upstream third holding device arranged in parallel with the first holding device in the orthogonal direction to hold the upstream portion of the multi-core shielded cable; a downstream third holding device arranged in parallel with the downstream first holding device in the orthogonal direction to hold the downstream portion of the multi-core shielded cable; and a first moving device. The first moving device moves at least one of a pair of third holding devices consisting of the upstream third holding device and the downstream third holding device and a pair of first holding devices consisting of the first holding device and the downstream first holding device in the orthogonal direction, thereby moving the pair of third holding devices relative to the pair of first holding devices in the orthogonal direction. The control device is configured to control the bending device so that the position of the upstream front end of the multi-core shielded cable is offset from the position of the downstream front end by a predetermined distance in the orthogonal direction. The control device is configured to: (1) cause one of the first holding device and the downstream first holding device to hold the multi-core shielded cable and cause the other to release the multi-core shielded cable, while causing the position of the upstream front end of the multi-core shielded cable to be offset from the position of the downstream front end by only the predetermined distance; (2) cause the third holding device corresponding to the first holding device that releases the multi-core shielded cable among the upstream third holding device and the downstream third holding device to hold the multi-core shielded cable and cause the third holding device corresponding to the first holding device that holds the multi-core shielded cable to release the multi-core shielded cable; and (3) further, control the first moving device so that the pair of third holding devices move only the predetermined distance in the orthogonal direction relative to the pair of first holding devices, so that the position of the upstream front end of the multi-core shielded cable in the orthogonal direction is aligned with the position of the downstream front end in the orthogonal direction.

[0027] According to the processing device for the multi-core shielded cable, even when the position of the upstream front end is offset from the position of the downstream front end when the multi-core shielded cable is bent, the position of the upstream front end can be aligned with the position of the downstream front end. Therefore, it is easy to process the front end portion based on the post-process processing device.

[0028] According to a preferred embodiment of the multi-core shielded cable processing device of the present invention, the first holding device is provided in the handover device, and the handover device receives the multi-core shielded cable from the pre-processing device through the first holding device and hands it over to the post-processing device.

[0029] According to the processing device for the multi-core shielded cable, a part of the positioning device and the handover device are made common, thereby making the processing device for the multi-core shielded cable compact.

[0030] According to a preferred embodiment of the processing device for a multi-core shielded cable of the present invention, the handover device further comprises a second moving device, and the second moving device moves the first holding device between an upstream handover position and a downstream handover position, wherein the upstream handover position is a position where the multi-core shielded cable is handed over between the front-process processing device and the first holding device, and the downstream handover position is a position where the multi-core shielded cable is handed over between the first holding device and the post-process processing device. The control device controls the second moving device to move the first holding device from the upstream handover position to the downstream handover position, and controls the first rotating device during the period when the first holding device moves from the upstream handover position to the downstream handover position to move the drain wire to the predetermined position.

[0031] According to the processing device of the multi-core shielded cable, the circumferential positioning of the drain wire can be performed while the multi-core shielded cable is moved in the conveying direction, so that the cycle time used for processing the multi-core shielded cable can be shortened.

[0032] According to a preferred embodiment of the multi-core shielded cable processing device of the present invention, the control device controls the first rotating device to rotate the multi-core shielded cable based on the detection of the detection device so that the drain wire faces the detection device, and then moves the drain wire to the predetermined position.

[0033] According to the processing device of the multi-core shielded cable, a preliminary alignment of the drain wire is performed so that the circumferential position of the drain wire is toward the position of the detection device. Since the circumferential position of the drain wire is toward the position of the detection device, the preliminary alignment of the drain wire can be accurately performed. Since the preliminary alignment of the drain wire can be accurately performed, the subsequent alignment of the drain wire can also be performed more accurately.

[0034] (III) Beneficial effects

[0035] According to the present invention, it is possible to improve the efficiency of a processing device for a multi-core shielded cable that is configured to separate a drain wire from a core wire before processing of a front end portion. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] [Structure of processing device]

[0052] The following describes the embodiments of the present invention with reference to the accompanying drawings. Figure 1 Here, the multi-core shielded cable 1 which is the target of the wire processing will be described. Figure 1 FIG. 1 is a schematic cross-sectional view of an example of a multi-core shielded cable 1. Figure 1 As shown, the multi-core shielded cable 1 has: a sheath 2, a noise-draining wire 3, a plurality of core wires 4, and a shielding layer 5. The sheath 2 is composed of an insulator, covering the noise-draining wire 3, the plurality of core wires 4 and the shielding layer 5. The plurality of core wires 4 are used, for example, as signal wires for transmitting electrical signals. The plurality of core wires 4 each have a core 4a and a coating 4b of an insulator covering the core 4a. The shielding layer 5 is a conductor that shields the core wire 4 from external noise. The shielding layer 5 covers the outside of the plurality of core wires 4. The noise-draining wire 3 is electrically connected to the shielding layer 5. The noise-draining wire 3 is grounded to ground the shielding layer 5. The noise-draining wire 3 is composed of a plurality of thinner conductor wires and is not covered with an insulator. The noise-draining wire 3 and the plurality of core wires 4 are twisted inside the shielding layer 5, which is omitted in the figure. The number of core wires 4 is not particularly limited. The number of core wires 4 only needs to be one or more. In the following, when there is no need to specifically distinguish between the noise-draining wire 3 and the plurality of core wires 4, they are collectively referred to as electric wires.

[0053] Figure 2 It is a schematic top view of a processing device (hereinafter referred to as a processing device) 10 for a multi-core shielded cable 1 according to one embodiment. The processing device 10 is a device that performs insulation treatment on the drain wire 3, and crimps the terminal 7 at the front end thereof, and further crimps the terminal 7 at the front ends of the plurality of core wires 4. Here, the insulation treatment of the drain wire 3 is to put a heat shrink tube 6 on the drain wire 3 and perform heat shrinkage on the heat shrink tube 6. The processing device 10 can be configured to also perform a process of installing a waterproof rubber plug on the drain wire 3 and the plurality of core wires 4.

[0054] Next, the transmission path of the multi-core shielded cable 1 is formed. Figure 2 The lower side of the processing device 10 is referred to as the front side of the processing device 10. The left and right sides of the processing device 10 refer to the left and right sides when viewed from the front side toward the rear side of the processing device 10. In the drawings, the front, rear, left, right, top, and bottom are represented by the reference numerals F, Rr, L, R, U, and D, respectively. However, the above directions are merely directions set for the convenience of explanation, and do not limit the installation method of the processing device 10.

[0055] like Figure 2As shown, the processing device 10 of this embodiment comprises: a front-process processing device 10A, which at least strips the sheath 2 of the multi-core shielded cable 1; and a post-process processing device 10B, which processes the front end of at least a part of the drain wire 3 and the multiple core wires 4. The front end of a part of the drain wire 3 and the multiple core wires 4 may not be processed by the post-process processing device 10B. The post-process processing device 10B is arranged in an array with the front-process processing device 10A in the conveying direction of the multi-core shielded cable 1 (here, the left direction). In detail, the post-process processing device 10B is arranged at a position downstream (here, the left) of the conveying direction of the multi-core shielded cable 1 than the front-process processing device 10A. In this embodiment, the front-process processing device 10A is configured to hold the portion of the multi-core shielded cable 1 covered by the sheath 2, and the post-process processing device 10B is configured to hold the drain wire 3 and the multiple core wires 4 separately. In this embodiment, the front-process processing device 10A and the post-process processing device 10B are separated due to different holding methods. Therefore, the processing apparatus 10 of the present embodiment further includes a delivery device 150 that receives the multi-core shielded cable 1 from the previous process apparatus 10A and transfers it to the subsequent process apparatus 10B.

[0056] In the present embodiment, the front-end processing device 10A comprises: a cutting and forming device 20, which cuts the multi-core shielded cable 1 into a specified length and bends it into a U shape; a semi-peeling device 30, which performs a semi-peeling process of forming a slit on the sheath 2 and pulling it out halfway; a core wire separation device 40, which completely pulls out the sheath 2 on the front end side and separates the drain wire 3 from the multiple core wires 4; and a tube installation device 50, which installs the heat shrink tube 6 on the drain wire 3. However, the above-mentioned devices and processes of the front-end processing device 10A are only preferred examples and are not particularly limited. These devices are arranged in sequence toward the downstream side of the conveying direction of the multi-core shielded cable 1.

[0057] like Figure 2As shown, the front-end processing device 10A includes a conveying device 110 for conveying the multi-core shielded cable 1 from the cutting and forming device 20 to the pipe installation device 50. The conveying device 110 includes: a plurality of conveying jigs 111 arranged along the conveying direction of the multi-core shielded cable 1; a driving unit 112 for moving the plurality of conveying jigs 111 along the conveying direction; and a plurality of fixing jigs 120 arranged in a manner arranged in the front-to-back direction (a direction orthogonal to the conveying direction, hereinafter also referred to as the orthogonal direction) with each device of the front-end processing device 10A. The plurality of conveying jigs 111 and the plurality of fixing jigs 120 each hold the multi-core shielded cable 1 (in detail, the straight line portion on the upstream side or the downstream side) in a manner such that the length direction of the multi-core shielded cable 1 (here, the length direction of the two straight line portions bent into a U shape) is consistent with the orthogonal direction (front-to-back direction). The conveying jig 111 conveys the multi-core shielded cable 1 between the plurality of fixing jigs 120. As a result, the plurality of multi-core shielded cables 1 are sequentially conveyed downstream in the conveying direction. In addition, the number of the transport jigs 111 may be one instead of multiple.

[0058] The post-processing device 10B includes: an arranging device 60, which holds the noise-reducing wire 3 and the multiple core wires 4 separately and arranges them at the same intervals; a stripping device 70, which strips off the heat shrink tube 6 wrapped around the noise-reducing wire 3 and the coating 4b of the multiple core wires 4; a crimping device 80, which crimps the terminal 7 to the noise-reducing wire 3 and the multiple core wires 4; and a discharging device 90, which discharges the multi-core shielded cable 1.

[0059] like Figure 2 As shown, the post-process processing device 10B has a reciprocating (Japanese original: シャトル) conveying device 130 for conveying the multi-core shielded cable 1 from the arrangement device 60 to the discharge device 90. The reciprocating conveying device 130 has: a plurality of reciprocating mechanisms 131, each of which has a holding portion 131a for individually holding the drain wire 3 and the plurality of core wires 4; and a driving portion 132, which causes the plurality of reciprocating mechanisms 131 to circulate. In addition, the number of the reciprocating mechanisms 131 may not be multiple, but one. In addition, the reciprocating mechanism 131 may not move in a circular motion, but may move back and forth.

[0060] The following describes the structures of each device of the front-process processing device 10A, each device of the back-process processing device 10B, and the handover device 150. The cutting and forming device 20 of the front-process processing device 10A cuts the multi-core shielded cable 1 into a predetermined length and forms it into a U shape. The cutting and forming device 20 includes: a feeding device 21 that feeds the multi-core shielded cable 1; a length measuring device 22 that measures the length of the multi-core shielded cable 1; a cutting device 23 that cuts the multi-core shielded cable 1 into a predetermined length; and a bending device 24 that bends the cut multi-core shielded cable 1 into a U shape. The bending device 24 bends the multi-core shielded cable 1 into a U shape in such a way that both ends are arranged in the conveying direction. Thus, the bending device 24 forms on the multi-core shielded cable 1: an upstream side portion 1u extending in the orthogonal direction, a downstream side portion 1d extending in the orthogonal direction downstream of the upstream side portion 1u in the conveying direction, and a bent portion 1m bent between the upstream side portion 1u and the downstream side portion 1d. Hereinafter, the front end portion (release end) of the upstream side portion 1u is also referred to as the upstream side end portion of the multi-core shielded cable 1, and the front end portion of the downstream side portion 1d is also referred to as the downstream side end portion of the multi-core shielded cable 1. The sheath 2 is stripped from the upstream side end portion and the downstream side end portion of the multi-core shielded cable 1, and the terminal 7 is crimped to the drain wire 3 and the core wire 4 exposed by stripping the sheath.

[0061] Here, the bending device 24 includes: an arc-shaped guide rail (not shown) for moving the second conveying fixture 111 from the upstream in the conveying direction to the front of the conveying fixture 111 on the most upstream side in the conveying direction; and a driving unit (at Figure 2 The second conveying fixture 111 from upstream is arranged in front of the most upstream conveying fixture 111, and the multi-core shielded cable 1 before bending is gripped. From this state, the second conveying fixture 111 is moved to the downstream side of the most upstream conveying fixture 111 in the conveying direction, thereby bending the multi-core shielded cable 1 into a U shape. After the multi-core shielded cable 1 is formed into a U shape, the conveying fixture 111 on the most upstream side grips the upstream side portion 1u of the multi-core shielded cable 1. The second conveying fixture 111 from upstream grips the downstream side portion 1d of the multi-core shielded cable 1.

[0062] The semi-stripping device 30 includes: a cutting device 31 for forming a slit in the sheath 2, and a pulling device 32 for pulling out the sheath 2 halfway. In the semi-stripping process, the pulling device 32 moves the sheath 2 on the front end side toward the front end side of the multi-core shielded cable 1 while rotating the sheath 2 on the root side in the circumferential direction. Thus, the pulling device 32 untangles the twist of the drain wire 3 and the plurality of core wires 4.

[0063] The core wire separation device 40 separates the multiple core wires 4 from the drain wire 3 by bending the multiple core wires 4 . Figure 3 4 is a schematic top view of the core wire separating device 40 . Figure 4 4 is a schematic rear view of the core wire separation device 40 . Figure 4 4 is a diagram showing a state where the core wire 4 is separated. Figure 3 As shown, a rotating device 125 for rotating the multi-core shielded cable 1 around an axis is connected to the fixing fixture 120 disposed in front of the core wire separation device 40. The multi-core shielded cable 1 is rotated by the rotating device 125 so that the drain wire 3 is at the 0 o'clock position (refer to Figure 4 ). A detection device 140 is provided above the fixing fixture 120, and the detection device 140 detects the circumferential position of the drain wire 3 when the multi-core shielded cable 1 is held by the fixing fixture 120. The rotation of the rotating device 125 is controlled based on the detection by the detection device 140. The core wire separation device 40 retains the drain wire 3 positioned at the 0 o'clock direction, and bends the core wire 4 located at other positions downward, thereby separating the drain wire 3 from the core wire 4.

[0064] Figure 5 It is a three-dimensional view of the fixing clamp 120 and the detection device 140 in front of the core wire separation device 40. Hereinafter, the reference numeral 120A is used to distinguish the fixing clamp 120 in front of the core wire separation device 40 from other fixing clamps 120. In addition, when the reference numeral 120A is used, the fixing clamp 120A in front of the core wire separation device 40 is sometimes simply referred to as the fixing clamp 120A. The fixing clamp 120A, like other fixing clamps 120, holds the multi-core shielded cable 1 in such a manner that the length direction of the multi-core shielded cable 1 is consistent with the orthogonal direction. Figure 5 As shown, the fixing fixture 120A includes: a left fixture 120L that contacts the multi-core shielded cable 1 that moves to the front of the core wire separation device 40 from the left, and a right fixture 120R that contacts the multi-core shielded cable 1 from the right. The left fixture 120L and the right fixture 120R respectively include clamping plates 121L and 121R, which are configured to be movable in the conveying direction and to contact or separate from the multi-core shielded cable 1. In addition, the left fixture 120L and the right fixture 120R respectively include driving parts 122L and 122R, which move the clamping plates 121L and 121R in the conveying direction and make the clamping plates 121L and 121R hold or release the multi-core shielded cable 1. Here, the driving parts 122L and 122R are cylinders. However, the types of the driving parts 122L and 122R are not particularly limited.

[0065] The rotating device 125 rotates the multi-core shielded cable 1 held by the fixing clamp 120A around a predetermined rotation axis Ax extending in an orthogonal direction. Here, the rotation axis Ax coincides with the axis of the multi-core shielded cable 1 held by the fixing clamp 120A. The rotating device 125 moves the left clamp 120L downward or upward, and moves the right clamp 120R upward or downward. The rotating device 125 moves the left clamp 120L and the right clamp 120R in directions offset from each other. Thus, the rotating device 125 rotates the multi-core shielded cable 1 around the rotation axis Ax. Figure 5 In FIG. 1 , arrows are used to indicate that the left clamp 120L is moved downward and the right clamp 120R is moved upward. The rotation direction of the multi-core shielded cable 1 is determined based on the circumferential position of the drain wire 3 detected by the detection device 140 .

[0066] The detection device 140 detects the circumferential position of the drain wire 3, for example, a camera. Here, the detection device 140 detects in sequence: the circumferential position of the drain wire 3 on the upstream side of the multi-core shielded cable 1 on the upstream side portion 1u, and the circumferential position of the drain wire 3 on the downstream side on the downstream side portion 1d. The detection device 140, for example, identifies the drain wire 3 based on the image of the multi-core shielded cable 1 captured by using the brightness difference with the core wire 4. However, the detection method of the drain wire 3 by the detection device 140 is not limited to the method of capturing the image of the drain wire 3. The position of the drain wire 3 can be detected, for example, by a detector that allows current to flow through the drain wire 3. Here, the detection device 140 is configured at the 0 o'clock position around the rotation axis Ax when observed in the front-to-back direction (observed in the axial direction of the rotation axis Ax). The control device 200 rotates the multi-core shielded cable 1 based on the detection of the detection device 140 so that the drain wire 3 faces the detection device 140, which will also be described in the description of the control device 200. As a result, the drain wire 3 moves to the 0 o'clock position. By positioning the drain wire 3 at a circumferential position toward the detection device 140, the position of the drain wire 3 can be accurately controlled. In addition, the position of the detection device 140 around the rotation axis Ax is not limited to the 0 o'clock position, and can be set to various circumferential positions.

[0067] like Figure 3 as well as Figure 4As shown, the core wire separation device 40 includes a pair of left and right hooks 41, a hook opening and closing device 42, and a hook moving device 43. The pair of hooks 41 are opened and closed by moving in the left and right directions in a manner of moving away from or approaching each other. The hook opening and closing device 42 is a driving unit that opens and closes the pair of hooks 41. The hook moving device 43 is a driving unit that moves the pair of hooks 41 in the up and down directions. When the pair of hooks 41 are closed, the pair of hooks 41 surround the multi-core shielded cable 1 except for the direction of 0 o'clock when viewed in the front and back directions. In this state, if the pair of hooks 41 are moved downward by the hook moving device 43, the multiple core wires 4 are hooked on the pair of hooks 41 and bent downward. The noise-draining wire 3 is not hooked on the pair of hooks 41 and remains. As a result, the noise-draining wire 3 is separated from the multiple core wires 4. As shown in FIG. Figure 3 As shown, the core wire separating device 40 further includes a pulling device 44 for completely pulling out the half-stripped sheath 2 from the multi-core shielded cable 1 .

[0068] The tube installation device 50 performs insulation treatment on the drain wire 3 by installing the heat shrink tube 6 of an insulator on the drain wire 3. The tube installation device 50 installs the heat shrink tube 6 on the drain wire 3 moving toward the detection device 140 (here, toward the 0 o'clock position). By determining the circumferential position of the drain wire 3, it is easy to install the heat shrink tube 6 on the drain wire 3. The tube installation device 50 includes: a tube reel 51, which is wound with the heat shrink tube 6 before cutting; a cutting device 52, which cuts the heat shrink tube 6 into a predetermined length; an insertion device 53, which inserts the drain wire 3 into the heat shrink tube 6; and a heating device 54, which heats the heat shrink tube 6 in the state where the drain wire 3 is inserted. The drain wire 3 moves to the 0 o'clock position (the front of the insertion device 53), so the insertion device 53 holds the heat shrink tube 6 and moves forward, so that the heat shrink tube 6 can be inserted outside the drain wire 3. However, the method of insulating the drain wire 3 is not limited to the method of putting the heat shrink tube 6 on the drain wire 3. The insulation treatment of the noise-draining wire 3 can be performed, for example, by winding an insulating tape on the noise-draining wire 3.

[0069] If the multi-core shielded cable 1 after the insulation treatment of the noise suppression wire 3 is completed is moved to the downstream side of the conveying direction of the pipe installation device 50 through the conveying clamp 111, the handover device 150 holds the multi-core shielded cable 1. If the handover device 150 holds the multi-core shielded cable 1, the conveying clamp 111 releases the multi-core shielded cable 1 and returns to the upstream side of the conveying direction. Hereinafter, the position of the clamps 160R and 160L (described later) of the handover device 150 when handing over the multi-core shielded cable 1 between the front-process processing device 10A will also be referred to as the upstream handover position P1. In addition, the handover device 150 transfers the multi-core shielded cable 1 to the post-process processing device 10B. Hereinafter, the position of the clamps 160R and 160L of the handover device 150 when handing over the multi-core shielded cable 1 between the post-process processing device 10B will also be referred to as the downstream handover position P2. The delivery device 150 is configured to move the clamps 160R and 160L between an upstream delivery position P1 and a downstream delivery position P2. The details of the delivery device 150 will be described later.

[0070] The arrangement device 60 is arranged at the most upstream side of the post-processing device 10B, and holds the drain wire 3 and the multiple core wires 4 separately and arranges them at the same pitch. The arrangement device 60 is configured to press the drain wire 3 and the core wire 4 into the holding portion 131a of the reciprocating mechanism 131, and the holding portion 131a is configured to hold the drain wire 3 and the core wire 4 separately. The holding portion 131a has a plurality of grooves that can respectively hold the wires and are arranged along the conveying direction. The arrangement device 60 thus arranges the drain wire 3 and the multiple core wires 4 in a manner arranged in the conveying direction. When the handover device 150 is handed over to the arrangement device 60, the drain wire 3 and the multiple core wires 4 of the multi-core shielded cable 1 are arranged in the conveying direction, and the details will be described in the description of the handover device 150. The arrangement device 60 is configured to receive the drain wire 3 and the multiple core wires 4 using a comb-shaped component with grooves arranged in the conveying direction, and press them into the holding portion 131a.

[0071] The stripping device 70 is arranged downstream of the arrangement device 60 in the conveying direction, and strips the heat shrink tube 6 on the drain wire 3 and the front end of the coating 4b of the plurality of core wires 4. The stripping by the stripping device 70 is performed on the drain wire 3 and the plurality of core wires 4 in sequence. In the stripping process, the stripping length and the cutting depth can be different between the drain wire 3 and the core wire 4.

[0072] The crimping device 80 is disposed at a position downstream of the stripping device 70 in the conveying direction, and crimps the terminal 7 to the drain wire 3 and the plurality of core wires 4. The crimping device 80 crimps the terminal 7 to the drain wire 3 and the plurality of core wires 4 in sequence. Here, the crimping device 80 includes: a right crimping device 80R that crimps the terminal 7 to the drain wire 3 and the core wire 4 on the downstream side, and a left crimping device 80L that crimps the terminal 7 to the drain wire 3 and the core wire 4 on the upstream side. The discharge device 90 includes a tray 91, into which the multi-core shielded cable 1 after the terminal 7 is crimped falls.

[0073] [Structure of the transfer device]

[0074] Next, the structure of the delivery device 150 will be described. Figure 6 It is a perspective view of the delivery device 150 . Figure 7 1 is a rear view of the interface 150. Figure 6 and Figure 7 As shown, the delivery device 150 includes an upstream clamp 160R, an upstream rotating device 170R, a downstream clamp 160L, a downstream rotating device 170L, and a slide device 180 .

[0075] The upstream clamp 160R is arranged between the front-process processing device 10A and the back-process processing device 10B, and holds the multi-core shielded cable 1 in a manner that the length direction and the orthogonal direction are consistent. In addition, the case where the upstream clamp 160R is arranged "between the front-process processing device 10A and the back-process processing device 10B" also includes the case where the position of the upstream clamp 160R in the conveying direction overlaps with the position of the front-process processing device 10A or the back-process processing device 10B in the conveying direction when the multi-core shielded cable 1 is handed over. The same is true for the downstream clamp 160L. The upstream clamp 160R holds the upstream side portion 1u of the multi-core shielded cable 1. The upstream rotating device 170R rotates the multi-core shielded cable 1 held by the upstream clamp 160R around the upstream rotating shaft 171R extending in the orthogonal direction. Here, the upstream rotating device 170R is configured to rotate the upstream clamp 160R around the upstream rotating shaft 171R. The upstream rotating device 170R rotates the upstream clamp 160R around the upstream rotating shaft 171R to rotate the upstream portion 1 u of the multi-core shielded cable 1 around the upstream rotating shaft 171R.

[0076] like Figure 6 As shown, the upstream clamp 160R includes: a pair of left and right gripping claws 161R, and a driving unit 162R, which makes the pair of gripping claws 161R approach or move away to grip or release the upstream side portion 1u of the multi-core shielded cable 1. Here, the driving unit 162R is a cylinder. However, the structure of the driving unit 162R is not particularly limited. The driving unit 162R may also include an electric motor, for example. Figure 6The delivery device 150 is shown when receiving the multi-core shielded cable 1 from the previous process processing device 10A (hereinafter also referred to as “before rotation”). At this time, the grip claw 161R is located at the lower end of the upstream clamp 160R.

[0077] like Figure 6 As shown, the upstream rotating device 170R includes: an upstream rotating shaft 171R that rotatably supports the upstream clamp 160R, a cylinder 172R that includes a rod 172R1 that can be extended and retracted, and a connecting portion 173R that swingably connects the rod 172R1 and the upstream clamp 160R. The upstream rotating shaft 171R is arranged to be offset from a line passing through the axis of the upstream portion 1u when the upstream clamp 160R holds the upstream portion 1u of the multi-core shielded cable 1. Therefore, if the rod 172R1 is extended and retracted, the multi-core shielded cable 1 does not rotate around the axis in situ, but revolves around the upstream rotating shaft 171R. Figure 6 As shown, in the state before the upstream clamp 160R is rotated, the rod 172R1 is extended.

[0078] Figure 8 This is a rear view of the delivery device 150 after the upstream clamp 160R and the downstream clamp 160L are rotated. Fig. 9 ), then Figure 8 As shown, the upstream clamp 160R rotates counterclockwise when viewed from behind (clockwise when viewed from the front). The upstream portion 1u of the multi-core shielded cable 1 held by the upstream clamp 160R moves toward the downstream side in the conveying direction. The upstream rotating device 170R rotates the upstream clamp 160R in such a way that the line through which the axis of the upstream portion 1u passes moves toward the downstream side in the conveying direction.

[0079] The upstream rotating device 170R rotates the multi-core shielded cable 1 to move the drain wire 3 to a predetermined position around the upstream rotating axis 171R. Here, the upstream rotating device 170R rotates the upstream clamp 160R by 90 degrees or approximately 90 degrees to move the drain wire 3 of the upstream portion 1u among the drain wire 3 and the multiple core wires 4 to the most upstream in the conveying direction. In the present embodiment, the upstream rotating device 170R rotates the upstream portion 1u of the multi-core shielded cable 1 by the following angle: the angle and the position of the detection device 140 around the rotating axis Ax (here, the 0 o'clock position, refer to Figure 5 ) is equal to the angle between the upstream side portion 1u and the conveying direction (here 90 degrees). The upstream rotating device 170R thus moves the noise-draining wire 3 to the most upstream of the conveying direction. In addition, the handover of the multi-core shielded cable 1 from the front-process processing device 10A to the handover device 150 is carried out in a manner that maintains the noise-draining wire 3 at the 0 o'clock position in the upstream side portion 1u and the downstream side portion 1d, respectively.

[0080] The downstream clamp 160L and the downstream rotating device 170L are configured to be symmetrical with the upstream clamp 160R and the upstream rotating device 170R, respectively. The downstream clamp 160L is disposed on the downstream side of the conveying direction relative to the upstream clamp 160R, and holds the downstream portion 1d of the multi-core shielded cable 1. The downstream rotating device 170L rotates the downstream portion 1d held by the downstream clamp 160L around a downstream rotating shaft 171L extending in an orthogonal direction. Figure 7 As shown, the downstream rotating shaft 171L is also provided so as to be offset from the line passing through the axis line of the downstream portion 1 d when the downstream clamp 160L grips the downstream portion 1 d of the multi-core shielded cable 1 .

[0081] The downstream side clamp 160L includes: a pair of left and right gripping claws 161L, and a driving unit 162L, which moves the pair of gripping claws 161L closer or farther away to grip or release the downstream side portion 1d of the multi-core shielded cable 1. The downstream side rotating device 170L includes: a downstream side rotating shaft 171L, a cylinder 172L with a rod that can be extended and retracted (see Figure 6 ), and a connecting portion that connects the rod to the downstream clamp 160L in a swingable manner. In this embodiment, if the rod of the cylinder 172L is retracted, as shown in FIG. Figure 7 As shown in FIG. 1 , the downstream clamp 160L rotates clockwise when viewed from behind (counterclockwise when viewed from the front). The downstream portion 1d of the multi-core shielded cable 1 held by the downstream clamp 160L moves toward the upstream side in the conveying direction. If both the upstream cylinder 172R and the downstream cylinder 172L are contracted, the upstream portion 1u and the downstream portion 1d of the multi-core shielded cable 1 approach each other.

[0082] The downstream rotating device 170L rotates the multi-core shielded cable 1 to move the drain wire 3 to a predetermined position around the downstream rotating axis 171L. Here, the downstream rotating device 170L rotates the downstream clamp 160L by 90 degrees or approximately 90 degrees, and moves the drain wire 3 of the downstream portion 1d to the most downstream in the conveying direction among the drain wire 3 and the plurality of core wires 4. Similar to the upstream rotating device 170R, the downstream rotating device 170L rotates the downstream portion 1d of the multi-core shielded cable 1 only by the following angle: the angle is equal to the angle between the position of the detection device 140 around the rotating axis Ax (here, the 0 o'clock position) and the conveying direction (here, 90 degrees).

[0083] The upstream clamp 160R, the upstream rotating device 170R, the downstream clamp 160L and the downstream rotating device 170L together with the rotating device 125 of the previous process processing device 10A constitute a positioning device 100 (see Figure 2). In this embodiment, the positioning device 100 includes: a portion provided in the pre-processing device 10A, and a portion arranged between the pre-processing device 10A and the post-processing device 10B. However, as shown in other embodiments described later, the positioning device 100 may not be arranged in a dispersed manner.

[0084] like Figure 2 As shown, the slide device 180 moves the clamps 160R and 160L between the upstream handover position P1 and the downstream handover position P2, wherein the upstream handover position P1 is the position where the multi-core shielded cable 1 is handed over between the front process processing device 10A and the clamps 160R and 160L, and the downstream handover position P2 is the position where the multi-core shielded cable 1 is handed over between the clamps 160R and 160L and the post-process processing device 10B. Figure 6 As shown, the slide device 180 includes a moving part 181, and the moving part 181 supports the upstream rotating device 170R, the downstream rotating device 170L, the upstream clamp 160R, and the downstream clamp 160L. The upstream clamp 160R and the downstream clamp 160L are supported on the moving part 181 via the upstream rotating device 170R and the downstream rotating device 170L, respectively. The slide device 180 also includes: a guide rail 182 that extends along the conveying direction and is slidably engaged with the moving part 181; and a cylinder 183 that moves the moving part 181 along the guide rail 182. Figure 6 As shown, the cylinder 183 is arranged on the downstream side of the guide rail 182, and moves the moving member 181 to the downstream side of the conveying direction by contracting the rod 183a. The cylinder 183 moves the moving member 181 to the upstream side of the conveying direction by extending the rod 183a. However, the mechanism for moving the clamps 160R and 160L between the upstream side handover position P1 and the downstream side handover position P2 is not limited to the above mechanism. For example, the slide device 180 can also move the moving member 181 along the conveying direction by a ball screw and a motor that rotates the ball screw.

[0085] The handover device 150 is configured to control the upstream rotating device 170R and the downstream rotating device 170L to rotate the multi-core shielded cable 1 while the clamps 160R and 160L move from the upstream handover position P1 to the downstream handover position P2. By moving and rotating the clamps 160R and 160L in parallel, the handover time of the multi-core shielded cable 1 is reduced. Fig. 9 FIG. 1 is a perspective view of the delivery device 150 after the upstream clamp 160R and the downstream clamp 160L are rotated and moved laterally. Fig. 9At the downstream handover position P2 shown by the solid line, the handover device 150 hands over the multi-core shielded cable 1 to the post-processing device 10B. At this time, the drain wire 3 of the upstream part 1u of the multi-core shielded cable 1 is located at the most upstream, and the drain wire 3 of the downstream part 1d is located at the most downstream. Fig. 9 The two-dot chain line indicates the moving member 181 and its carried objects when located at the upstream delivery position P1.

[0086] In addition, in the handover device 150, as the distance in the conveying direction between the upstream side portion 1u and the downstream side portion 1d of the multi-core shielded cable 1 (hereinafter, also referred to as the distance between both ends of the multi-core shielded cable 1) becomes narrower, the post-process processing device 10B is configured to correspond to the multi-core shielded cable 1 with a narrow distance between both ends. As a result, the length of the post-process processing device 10B in the conveying direction is shortened.

[0087] [Control device]

[0088] Fig.10 is a block diagram of the processing device 10. Fig.10 As shown, the processing device 10 includes a control device 200 for controlling a front process processing device 10A, a back process processing device 10B, a detection device 140, a positioning device 100, and a handover device 150. More specifically, the control device 200 is connected with: a feeding device 21, a length measuring device 22, a cutting device 23, and a bending device 24 of the cutting and forming device 20; a cutting device 31 and a pulling device 32 of the semi-peeling device 30; a hook opening and closing device 42, a hook moving device 43, and a pulling device 44 of the core wire separating device 40; a cutting device 52, an inserting device 53, and a heating device 54 of the pipe mounting device 50; an arranging device 60; a peeling device 70; a right crimping device 80R; and a left crimping device 80L. In addition, the control device 200 is connected with: the conveying fixture 111, the driving unit 112, the fixing fixture 120 (driving units 122L and 122R), and the rotating device 125 of the conveying device 110; the driving unit 132 of the reciprocating conveying device 130; the upstream side fixture 160R (driving unit 162R), the downstream side fixture 160L (driving unit 162L), the upstream side rotating device 170R (cylinder 172R), the downstream side rotating device 170L (cylinder 172L), and the sliding device 180 (cylinder 183) of the handover device 150 or the positioning device 100. The processing device 10 may also be equipped with other devices controlled by the control device 200, but the illustration and description are omitted here.

[0089] The structure of the control device 200 is not particularly limited. The control device 200 may include, for example, a central processing unit (hereinafter referred to as a CPU), a ROM and a RAM storing programs executed by the CPU, etc. Each part of the control device 200 may be composed of software or hardware. In addition, each part may be a processor or a circuit. The control device 200 may be, for example, a programmable controller, a computer, etc.

[0090] like Fig.10 As shown, the control device 200 includes an acquisition unit 201, which is connected to the detection device 140 and obtains the detection result of the detection device 140. In addition, the control device 200 includes a first rotation control unit 202 as a control unit related to the control of the rotation device 125, and includes a grip control unit 203, a movement control unit 204, and a second rotation control unit 205 as a control unit related to the control of the handover device 150. The control device 200 also includes a control unit for controlling devices other than the rotation device 125 and the handover device 150, but the illustration and description are omitted here.

[0091] The first rotation control unit 202 controls the rotation device 125 (the rotation device 125 that moves the fixing fixture 120A in front of the core wire separation device 40) based on the detection based on the detection device 140, so that the multi-core shielded cable 1 rotates so that the noise-draining wire 3 faces the detection device 140. Here, the first rotation control unit 202 rotates the upstream side portion 1u and the downstream side portion 1d of the multi-core shielded cable 1 in sequence based on the detection based on the detection device 140, so that the noise-draining wire 3 faces the detection device 140.

[0092] The gripping control unit 203 controls the upstream clamp 160R and the downstream clamp 160L of the handover device 150 to respectively grip the upstream portion 1u and the downstream portion 1d of the multi-core shielded cable 1. In addition, after the upstream portion 1u and the downstream portion 1d rotate, the upstream clamp 160R and the downstream clamp 160L are controlled to release the upstream portion 1u and the downstream portion 1d.

[0093] If the reception of the multi-core shielded cable 1 from the front-end processing device 10A is completed at the upstream handover position P1, the movement control unit 204 controls the slide device 180 to move the upstream clamp 160R and the downstream clamp 160L from the upstream handover position P1 to the downstream handover position P2. If the transfer of the multi-core shielded cable 1 to the back-end processing device 10B is completed at the downstream handover position P2, the movement control unit 204 controls the slide device 180 to move the upstream clamp 160R and the downstream clamp 160L from the downstream handover position P2 to the upstream handover position P1.

[0094] The second rotation control unit 205 controls the upstream rotation device 170R to rotate the upstream part 1u of the multi-core shielded cable 1, so that the drain wire 3 at the upstream end is moved to a predetermined position around the upstream rotation axis 171R. In addition, the second rotation control unit 205 controls the downstream rotation device 170L to rotate the downstream part 1d of the multi-core shielded cable 1, so that the drain wire 3 at the downstream end is moved to a predetermined position around the downstream rotation axis 171L. In detail, the upstream rotation device 170R rotates the upstream part 1u of the multi-core shielded cable 1 to move the drain wire 3 to the most upstream in the conveying direction among the drain wire 3 and the multiple core wires 4. In addition, the downstream rotation device 170L rotates the downstream part 1d of the multi-core shielded cable 1 to move the drain wire 3 to the most downstream in the conveying direction among the drain wire 3 and the multiple core wires 4. In this embodiment, the second rotation control unit 205 controls the upstream side rotation device 170R and the downstream side rotation device 170L to move the disturbance-eliminating wire 3 at the upstream side end to a predetermined circumferential position while the upstream side clamp 160R and the downstream side clamp 160L are moved from the upstream side handover position P1 to the downstream side handover position P2 under the control of the movement control unit 204.

[0095] In the present embodiment, the rotation angle of the multi-core shielded cable 1 in the handover device 150 is determined by the mechanism of the handover device 150, without electrical position control. However, the above control can also be performed by electrical position control. In this case, the upstream rotating device 170R and the downstream rotating device 170L can also be equipped with a servo motor or a stepping motor, for example. "Control of the upstream rotating device 170R and the downstream rotating device 170L" can include control accompanied by position control in addition to timing control not accompanied by position control as in the present embodiment.

[0096] The control device 200 controls the positioning device 100 (here, the rotating device 125, the upstream rotating device 170R, and the downstream rotating device 170L) based on the detection result of the detection device 140, so as to move the upstream and downstream drain wires 3 to predetermined positions around the upstream rotating shaft 171R and the downstream rotating shaft 171L, respectively. Before handing over the multi-core shielded cable 1 to the post-process processing device 10B, the control device 200 drives the upstream rotating device 170R and the downstream rotating device 170L. As a result, the upstream and downstream drain wires 3 move to predetermined positions around the upstream rotating shaft 171R and the downstream rotating shaft 171L, respectively.

[0097] [Processing procedures for multi-core shielded cables]

[0098] Hereinafter, a processing procedure of the multi-core shielded cable 1 will be described with reference to a flowchart. Fig.11A and Fig. 11B 1 is a flowchart showing the processing of the multi-core shielded cable 1. Fig.11A , 11B In the description thereof, details of the processes are omitted except for the rotation and handover process of the multi-core shielded cable 1 in the core wire separation process. Fig.11A In FIG. 11 and FIG. 11B, the multi-core shielded cable 1 is simply described as a "cable".

[0099] like Fig.11A As shown, in step S01 of the processing procedure of the multi-core shielded cable 1, the multi-core shielded cable 1 is cut into a predetermined length by the cutting and forming device 20 and bent into a U shape. In step S02, the multi-core shielded cable 1 is conveyed downstream in the conveying direction and moves to the front position of the half-peeling device 30. In step S03, the sheath 2 of the multi-core shielded cable 1 is half-peeled. In addition, although the description of the steps and Fig.11A , 11B Although the description is omitted, the half-stripping of the sheath 2 is performed sequentially on the downstream side portion 1d and the upstream side portion 1u of the multi-core shielded cable 1 bent into a U-shape. The same is true for other processing steps. In step S04, the multi-core shielded cable 1 is conveyed to the front of the core wire separation device 40. In step S05, the core wires 4 of the multi-core shielded cable 1 are separated by the core wire separation device 40. When the core wires 4 of the downstream side portion 1d are separated, the half-stripping of the sheath 2 of the upstream side portion 1u can be performed at the same time. The same is true for other continuous processing. However, the processing of the downstream side portion 1d and the processing of the upstream side portion 1u may not be performed at the same time.

[0100] Step S05 includes: step S051 of detecting the position of the drain wire 3; step S052 of rotating the multi-core shielded cable 1 according to the detected position of the drain wire 3; step S053 of completely pulling out the sheath 2; and step S054 of bending the core wire 4 at the downstream end. In step S051, the circumferential position of the drain wire 3 is determined by the detection device 140. In step S052, the multi-core shielded cable 1 is rotated by moving the left clamp 120L and the right clamp 120R of the fixing clamp 120A up and down in an offset manner, so that the drain wire 3 comes to the 0 o'clock position. The detection device 140 confirms that the drain wire 3 reaches the 0 o'clock position. In step S053, the sheath 2 on the front end side of the slit is pulled out from the multi-core shielded cable 1. In step S054, the hook 41 is hooked on the core wire 4 to bend the core wire 4 downward.

[0101] In step S06, the multi-core shielded cable 1 is conveyed and moved forward of the tube installation device 50. In step S07, the heat shrink tube 6 is installed on the drain wire 3. Thus, the processing by the pre-processing device 10A ends.

[0102] In step S08, the multi-core shielded cable 1 is transported from the front-process processing device 10A to the back-process processing device 10B via the handover device 150. Step S08 includes: step S081 in which the multi-core shielded cable 1 is transported to a position directly opposite to the handover device 150 by the transport device 110; step S082 in which the handover device 150 holds the multi-core shielded cable 1; step S083 in which the transport device 110 releases the multi-core shielded cable 1; step S084 in which the multi-core shielded cable 1 is transported by the handover device 150; and step S085 in which the upstream side portion 1u and the downstream side portion 1d of the multi-core shielded cable 1 are rotated. Prior to step S082, the upstream side clamp 160R and the downstream side clamp 160L of the handover device 150 are moved to the upstream side handover position P1. Steps S084 and S085 are performed simultaneously here.

[0103] Detailed description of steps S081 to S083 is omitted. In step S084, the multi-core shielded cable 1 is conveyed to the downstream handover position P2. In step S085 performed simultaneously with step S084, the upstream side clamp 160R and the downstream side clamp 160L are rotated 90 degrees inwardly in the conveying direction of the handover device 150. As a result, the drain wire 3 and the plurality of core wires 4 at the upstream end are arranged in such a manner that the drain wire 3 is located at the most upstream (outermost). In addition, the drain wire 3 and the plurality of core wires 4 at the downstream end are arranged in such a manner that the drain wire 3 is located at the most downstream (outermost). In addition, the distance in the conveying direction (the distance between the two ends) between the upstream side portion 1u and the downstream side portion 1d of the multi-core shielded cable 1 is shortened.

[0104] In step S09, the drain wires 3 and core wires 4 at the upstream and downstream ends are pressed into the holding portion 131a of the reciprocating mechanism 131 by the arranging device 60. Thus, the drain wires 3 and multiple core wires 4 at the upstream and downstream ends are arranged in a prescribed order in the conveying direction and are individually held.

[0105] In step S10, the reciprocating mechanism 131 moves downstream in the conveying direction, and the multi-core shielded cable 1 moves forward of the stripping device 70. In step S11, the heat shrink tube 6 on the drain wire 3 and the coating 4b of the core wire 4 are stripped by the stripping device 70. The stripping of step S11 is performed on each drain wire 3 and core wire 4 in sequence. At this time, the drain wire 3 is located on the most downstream side or the most upstream side in the conveying direction. Therefore, the stripping device 70 sets the stripping process for the wires located on the most downstream side or the most upstream side in the conveying direction (the number of wires is known in advance, and they are the first or last wires) as the drain wire 3. The stripping device 70 sets the stripping process for the other wires as the core wire 4.

[0106] In step S12, the reciprocating mechanism 131 is moved in such a manner that the multi-core shielded cable 1 is located in front of the crimping device 80. In step S13, the terminal 7 is crimped to the drain wire 3 and the plurality of core wires 4 by the crimping device 80. The crimping of step S13 is also performed sequentially on each drain wire 3 and core wire 4. Therefore, in the crimping process, the process can be easily and reliably performed by also determining the position (sequence) of the drain wire 3.

[0107] In step S14, the multi-core shielded cable 1 is discharged. Thus, the processing of the multi-core shielded cable 1 is completed. The above-mentioned processing flow of the multi-core shielded cable 1 is only a preferred example, and the processing order of the multi-core shielded cable 1 is not limited to this.

[0108] [Effects of the Embodiments]

[0109] Hereinafter, the effects that can be achieved by the processing device 10 of the multi-core shielded cable 1 according to the present embodiment will be described.

[0110] The processing device 10 of the multi-core shielded cable 1 of the present embodiment is provided with a detection device 140 for detecting the circumferential position of the drain wire 3. In addition, the positioning device 100 is provided with: an upstream side clamp 160R, which holds the multi-core shielded cable 1 in a manner that the length direction is consistent with the orthogonal direction; and an upstream side rotating device 170R, which rotates the multi-core shielded cable 1 held by the upstream side clamp 160R around an upstream side rotating axis 171R extending in the orthogonal direction. The control device 200 controls the positioning device 100 based on the detection result based on the detection device 140, so that the drain wire 3 on the upstream side moves to a predetermined position around the upstream side rotating axis 171R. Here, the control device 200 drives the rotating device 125 and the upstream side rotating device 170R to move the drain wire 3 on the upstream side to a predetermined position around the upstream side rotating axis 171R.

[0111] In the processing of the multi-core shielded cable 1, in the processing of the front end portions of the drain wire 3 and the core wire 4, each wire is processed separately. Therefore, it is preferable to identify the drain wire 3 and the core wire 4 separately before the processing by the post-process processing device 10B. The processing of the drain wire 3 and the processing of the core wire 4 are different in many cases, so it is preferable to at least distinguish and identify the drain wire 3 and the core wire 4. In the processing performed by the post-process processing device 10B such as stripping or crimping processing, the processing conditions are sometimes divided according to the drain wire 3 and the core wire 4. By distinguishing the drain wire 3 from the core wire 4, the setting of the processing conditions becomes easy. According to the processing device 10 of the present embodiment, the multi-core shielded cable 1 is rotated in a manner that the drain wire 3 moves to a predetermined circumferential position before being conveyed to the post-process processing device 10B that performs the processing of the front end. According to the position of the drain wire 3 after the movement, the drain wire 3 and the core wire 4 can be distinguished.

[0112] In the above description of the effects, the upstream clamp 160R and the upstream rotating device 170R are taken as an example, but the effects exerted by the downstream clamp 160L and the downstream rotating device 170L are also the same.

[0113] In the present embodiment, the upstream rotating device 170R rotates the multi-core shielded cable 1 in such a manner that the drain wire 3 is moved to the most upstream in the conveying direction among the drain wire 3 and the core wire 4. The downstream rotating device 170L rotates the multi-core shielded cable 1 in such a manner that the drain wire 3 is moved to the most downstream in the conveying direction among the drain wire 3 and the core wire 4. According to the processing device 10, the drain wire 3 is located at the end of the conveying direction in the post-process processing device 10B. Thus, in the processing of the drain wire 3 and the core wire 4, the processing of the drain wire 3 is the first or last. Therefore, when the processing of the drain wire 3 is different from that of the core wire 4, the number of production changes and adjustments can be minimized.

[0114] In the present embodiment, the detection device 140 is configured to detect the circumferential position of the drain wire 3 when the multi-core shielded cable 1 is held by the fixing fixture 120A of the front-process processing device 10A. The control device 200 controls the rotating device 125 to rotate the multi-core shielded cable 1 based on the detection of the detection device 140 so that the drain wire 3 faces the detection device 140, and then controls the upstream rotating device 170R and the downstream rotating device 170L to move the drain wires 3 on the upstream and downstream sides to predetermined positions.

[0115] According to the processing device 10, the circumferential position of the drain wire 3 in the state of being held by the fixing fixture 120A of the front-process processing device 10A is detected by the detection device 140, and the circumferential position of the drain wire 3 becomes a position facing the detection device 140. Thus, the circumferential position of the drain wire 3 is determined, and the processing of the drain wire 3 and the core wire 4 in the front-process processing device 10A (here, the core wire separation process and the heat shrink tube installation process) becomes easy. In addition, in the front-process processing device 10A, the circumferential position of the drain wire 3 is made to be a position facing the detection device 140, so that the drain wire 3 can be accurately aligned. Since the drain wire 3 in the front-process processing device 10A can be accurately aligned, the drain wire 3 in the handover device 150 can also be more accurately aligned.

[0116] According to the processing device 10 of the present embodiment, the position of the drain wire 3 in the circumferential direction is determined by the operation of the rotating device 125, so that the heat shrink tube 6 can be easily attached. As a result, the processing efficiency of the processing device 10 can be improved.

[0117] According to the processing device 10 of this embodiment, the position of the noise-draining wire 3 can be determined at the two ends of the multi-core shielded cable 1 that is bent into a U-shape in order to sequentially process the two ends. Therefore, the noise-draining wire 3 and the core wire 4 can be distinguished at both ends of the multi-core shielded cable 1. By bending the multi-core shielded cable 1 into a U-shape, the two ends can be processed at the same time, thereby improving the processing efficiency of the processing device 10.

[0118] In the present embodiment, the upstream rotating shaft 171R is arranged to be offset from the line through which the axis of the upstream portion 1u passes when the upstream clamp 160R holds the upstream portion 1u of the multi-core shielded cable 1. The upstream rotating device 170R is configured to rotate the upstream clamp 160R around the upstream rotating shaft 171R so that the line through which the axis of the upstream portion 1u passes moves to the downstream side in the conveying direction. In addition, the downstream rotating shaft 171L is arranged to be offset from the line through which the axis of the downstream portion 1d passes when the downstream clamp 160L holds the downstream portion 1d of the multi-core shielded cable 1. The downstream rotating device 170L is configured to rotate the downstream clamp 160L around the downstream rotating shaft 171L so that the line through which the axis of the downstream portion 1d passes moves to the upstream side in the conveying direction.

[0119] According to the processing device 10, the two ends of the multi-core shielded cable 1 are close to each other in the conveying direction, and the distance between the two ends is narrowed. Therefore, the length of the post-process processing device 10B in the conveying direction can be shortened, and the space efficiency can be improved. In addition, only the downstream side part 1d rotates toward the upstream side, or only the upstream side part 1u rotates toward the downstream side, which can also achieve the same effect.

[0120] In this embodiment, the upstream clamp 160R and the downstream clamp 160L are provided in the delivery device 150. The delivery device 150 is configured to receive the multi-core shielded cable 1 from the previous process device 10A through the upstream clamp 160R and the downstream clamp 160L and transfer it to the subsequent process device 10B.

[0121] According to the processing device 10, the positioning device 100 and the delivery device 150 are partially shared. As a result, the processing device 10 can be made compact and the space efficiency can be improved. In addition, the number of parts of the processing device 10 can be reduced, and the cost can be reduced.

[0122] In this embodiment, the control device 200 controls the sliding device 180 to move the clamps 160R and 160L from the upstream side handover position P1 to the downstream side handover position P2, and at the same time controls the upstream side rotating device 170R and the downstream side rotating device 170L during the period when the clamps 160R and 160L move from the upstream side handover position P1 to the downstream side handover position P2, so as to move the disturbance-eliminating wires 3 on the upstream and downstream sides.

[0123] According to the processing device 10, the drain wire 3 can be positioned in the circumferential direction while the multi-core shielded cable 1 is moved in the conveying direction. Therefore, the cycle time for processing the multi-core shielded cable 1 can be shortened.

[0124] [Modifications]

[0125] Hereinafter, a modification of the above embodiment will be described. In the following description of the modification and other embodiments, components having the same functions as the above embodiment are given the same reference numerals as those of the above embodiment. In addition, repeated descriptions are omitted or simplified.

[0126] In this modification, the control device 200 is configured to be able to control the bending device 24 so that the position of the upstream front end (the front end of the upstream part 1u) of the multi-core shielded cable 1 is offset from the position of the downstream front end (the front end of the downstream part 1d) by a predetermined distance in the orthogonal direction. In order to achieve this purpose, a pair of conveying clamps 111 in front of the cutting and forming device 20 are configured to be able to move in the front-back direction. By offsetting the position of the upstream front end and the downstream front end of the multi-core shielded cable 1 bent into a U shape in the orthogonal direction, the sheath stripping length of the upstream end can be made different from the sheath stripping length of the downstream end. As a result, the length of the wire exposed at the upstream end can be made different from the length of the wire exposed at the downstream end. The half-stripping device 30 cuts the sheath 2 at the upstream end and the sheath 2 at the downstream end at the same orthogonal position. Each device from the half-stripping device 30 to the pipe installation device 50 can be simply configured to align the cutting position of the sheath 2 at both ends of the multi-core shielded cable 1.

[0127] Fig.12 1 is a perspective view showing a state where a multi-core shielded cable 1 having front ends at different positions is held by a splicing device 150. Fig.12 As shown, if the multi-core shielded cable 1 with different front end positions at both ends is held by the handover device 150, the position of the orthogonal direction of the upstream front end of the multi-core shielded cable 1 and the position of the orthogonal direction of the downstream front end are only offset by a preset distance D1. In addition, in this state, the front end position of the sheath 2 of the upstream part 1u is aligned with the front end position of the sheath 2 of the downstream part 1d in the orthogonal direction.

[0128] like Fig.12As shown, in this variant, the handover device 150 includes an upstream adjustment fixture 190R and a downstream adjustment fixture 190L. The upstream adjustment fixture 190R is arranged in an orthogonal direction with the upstream fixture 160R to hold the upstream side portion 1u of the multi-core shielded cable 1. Here, the upstream adjustment fixture 190R is arranged behind the upstream side fixture 160R. The downstream adjustment fixture 190L is arranged in an orthogonal direction with the downstream side fixture 160L to hold the downstream side portion 1d of the multi-core shielded cable 1. The downstream adjustment fixture 190L is arranged behind the downstream side fixture 160L. A pair of adjustment fixtures 190 consisting of the upstream adjustment fixture 190R and the downstream adjustment fixture 190L is configured to be movable in an orthogonal direction, and is moved in the orthogonal direction by a moving device 191. Here, the pair of adjustment fixtures 190 move synchronously as a whole.

[0129] The processing device 10 of this modified example is configured to align the orthogonal position of the upstream front end of the multi-core shielded cable 1 with the orthogonal position of the downstream front end through the handover device 150 and a pair of adjustment fixtures 190. Each device from the arranging device 60 to the crimping device 80 can simply configure a method for aligning the front end positions of the wires at both ends of the multi-core shielded cable 1.

[0130] Fig.13 1 is a perspective view showing the delivery device 150 after the operation of aligning the front end positions of both ends of the multi-core shielded cable 1 has just begun. Fig.13 As shown, in the operation of aligning the front end positions of both ends of the multi-core shielded cable 1, the straight line portion (in the direction of the stripping length) of the side with the longer stripping length, that is, the side protruding in the orthogonal direction, is grasped. Fig.13 In the example of the upstream side portion 1u) of the adjustment fixture 190 (in Fig.13 In the example of the upstream adjustment jig 190R) releases the multi-core shielded cable 1. In addition, the straight line portion (in the upstream adjustment jig 190R) on the side with a shorter stripping length, that is, the side retreating in the orthogonal direction, is grasped. Fig.13 In the example of the downstream side portion 1d), the clamp 160 (in Fig.13 In the example of the downstream clamp 160L, the multi-core shielded cable 1 is released. Thus, the clamp 160 can be released by the action of the adjustment clamp 190 (here, the downstream adjustment clamp 190L) and the straight line portion held by the adjustment clamp 190, that is, the straight line portion retreated in the orthogonal direction (in Fig.13 In the example, the downstream side portion 1d) moves.

[0131] from Fig.13 From the state shown, the processing device 10 moves the pair of adjustment jigs 190 rearward. Fig.14 1 is a perspective view showing a state where the front end positions of both ends of the multi-core shielded cable 1 are aligned. Fig.14 In the example shown, the downstream side portion 1d is pulled by the downstream side adjustment clamp 190L and moves backward by the movement of the pair of adjustment clamps 190. The upstream side adjustment clamp 190R moves backward without holding the multi-core shielded cable 1. The portion of the multi-core shielded cable 1 held by the upstream side clamp 160R of the handover device 150 does not move, so the multi-core shielded cable 1 is deformed in such a way that the position of the other end is aligned with the front end of the side with a longer stripping length (refer to Fig.14 ). As a result, the upstream front end position of the multi-core shielded cable 1 is aligned with the downstream front end position in the orthogonal direction. Then, the downstream side clamp 160L of the handover device 150 grasps the downstream side portion 1d of the multi-core shielded cable 1 again, which is omitted from the illustration. In addition, the downstream side adjustment clamp 190L releases the downstream side portion 1d of the multi-core shielded cable 1.

[0132] In addition, the pair of adjustment jigs 190 may be respectively arranged behind or in front of the pair of jigs 160. In addition, the moving device 191 may be configured to move the pair of jigs 160 in the orthogonal direction, or may be configured to move both the pair of jigs 160 and the pair of adjustment jigs 190 in the orthogonal direction. That is, the moving device 191 only needs to be configured to move the pair of adjustment jigs 190 relative to the pair of jigs 160 in the orthogonal direction by moving at least one of the pair of adjustment jigs 190 and the pair of jigs 160 in the orthogonal direction.

[0133] In addition, the control device 200 only needs to be configured so that one of the upstream clamp 160R and the downstream clamp 160L holds the multi-core shielded cable 1 and the other releases the multi-core shielded cable 1, so that the adjustment clamp 190 corresponding to the clamp 160 that releases the multi-core shielded cable 1 holds the multi-core shielded cable 1, and the adjustment clamp 190 corresponding to the clamp 160 that holds the multi-core shielded cable 1 releases the multi-core shielded cable 1. In addition, the control device 200 only needs to be configured so that the control device 191 controls the moving device 191 so that the pair of adjustment clamps 190 moves only a distance D1 in the orthogonal direction relative to the pair of clamps 160, so that the orthogonal position of the upstream front end of the multi-core shielded cable 1 is aligned with the orthogonal position of the downstream front end. For example, the pair of adjustment clamps 190 may not pull the straight portion of the front end of the multi-core shielded cable 1 in the orthogonal direction, but press the protruding straight portion.

[0134] According to the processing device 10 of this modified example, even if the position of the upstream front end is offset from the position of the downstream front end when the multi-core shielded cable 1 is bent, the position of the upstream front end can be aligned with the position of the downstream front end. Therefore, it is easy to perform processing such as crimping of the terminal 7 by the post-process processing device 10B.

[0135] In addition, the pair of adjustment jigs 190R and 190L may be configured to be independently movable. In addition, the function of the adjustment jig 190 may also be realized by the transport jig 111 .

[0136] [Other embodiments]

[0137] The preferred embodiment of the present invention has been described above. However, the above-mentioned embodiment is only an example, and various other embodiments are also possible. For example, in the above-mentioned embodiment, the upstream side rotating device 170R and the upstream side clamp 160R are configured to move the drain wire 3 to the most upstream in the electric wire, and the downstream side rotating device 170L and the downstream side clamp 160L are configured to move the drain wire 3 to the most downstream in the electric wire. However, the position where the upstream side rotating device 170R moves the drain wire 3 and the position where the downstream side rotating device 170L moves the drain wire 3 are not particularly limited as long as they are predetermined positions.

[0138] In the above-mentioned embodiment, the positioning device 100 aligns the noise-draining wires 3 at both ends of the multi-core shielded cable 1 formed into a U shape. However, the positioning device 100 may also be configured to align the noise-draining wire 3 at one end of the multi-core shielded cable 1. In this case, the multi-core shielded cable 1 may not be bent into a U shape, for example, it may be directly conveyed in a straight line shape. In addition, in this case, the number of clamps 160 provided by the positioning device 100 may also be one.

[0139] In the above-mentioned embodiment, the rotating device 170 (indicates one or both of the upstream rotating device 170R and the downstream rotating device 170L) rotates the multi-core shielded cable 1 by rotating the clamp 160. However, the clamp 160 and the rotating device 170 may also be connected to each other. Figure 5 The fixing clamp 120A and the rotating device 125 shown are similarly constructed, and the multi-core shielded cable 1 is rotated without rotating the clamp 160. Alternatively, the clamp 160 can also rotate around the axis of the multi-core shielded cable 1 in a state of holding the multi-core shielded cable 1. In this case, the multi-core shielded cable 1 rotates around its axis without shaking. The way in which the handover device 150 rotates the multi-core shielded cable 1 is not particularly limited.

[0140] In the above embodiment, the multi-core shielded cable 1 is rotated in the previous process device 10A based on the detection by the detection device 140. However, the multi-core shielded cable 1 may be rotated between the previous process device 10A and the subsequent process device 10B based on the detection by the detection device 140.

[0141] For example, in other preferred processing devices 10 for multi-core shielded cables 1, the detection device 140 may also be configured to detect the circumferential position of the drain wire 3 when the multi-core shielded cable 1 is held by the clamp 160 of the handover device 150. The control device 200 may control the rotating device 170 of the handover device 150 based on the detection of the detection device 140, so as to rotate the multi-core shielded cable 1 so that the drain wire 3 faces the detection device 140, and then move the drain wire 3 to a specified position. In addition, the clamp that holds and rotates the multi-core shielded cable 1 may not be the clamp of the handover device 150, but may be other clamps arranged between the front-process processing device 10A and the back-process processing device 10B.

[0142] According to the processing device 10 of the multi-core shielded cable 1, preliminary alignment of the drain wire 3 is performed so that the circumferential position of the drain wire 3 is toward the position of the detection device 140. Since the circumferential position of the drain wire 3 is toward the position of the detection device 140, the preliminary alignment of the drain wire 3 can be accurately performed. Since the preliminary alignment of the drain wire 3 can be accurately performed, the subsequent alignment of the drain wire 3 can also be performed more accurately.

[0143] In addition, the processing device 10 may not perform the above-mentioned preliminary alignment of the noise-reducing wire 3, and may detect whether the noise-reducing wire 3 has moved to the specified circumferential position through the detection device 140, and control the rotating device 170 based on the detection of the detection device 140.

[0144] The handover device 150 may also align the drain wire 3 at the position where the multi-core shielded cable 1 is received from the conveying fixture 111 of the previous process processing device 10A, and hand over the multi-core shielded cable 1 to the subsequent process processing device 10B.

[0145] The multi-core cable processed by the processing device 10 may not be the multi-core shielded cable 1 including the drain wire 3 and one or more core wires 4. The processing device 10 is configured to separate specific wires from other wires before processing the front end of the wires, and the type of multi-core cable processed is not limited.

[0146] The configurations of the pre-processing apparatus 10A and the post-processing apparatus 10B are merely preferred examples and are not limited to the above configurations. In addition, the above-described embodiments do not limit the present invention unless otherwise specified.
