Description

[Technical Field]

[0001] The present invention relates to a wire inversion checking device that checks whether two striped wires are arranged without the stripe colors being inverted relative to the normal color order. [Background technology]

[0002] Conventionally, striped electric wires, in which color stripes indicating the intended use are formed on the surface of the wire coating, have been widely used. Two such striped electric wires are often arranged alongside each other and supplied, for example, for connection to a connector. In such cases, it is desirable that the stripe colors are arranged in the wire arrangement direction without being reversed from the regular color order for each intended use, so that the two striped electric wires are supplied to the correct destination for each intended use. Currently, in many cases, workers visually check whether the stripe color order has been reversed when supplying striped electric wires. Because this type of work tends to be a burden for workers, it is desirable to be able to automatically check whether the stripe color order has been reversed.

[0003] Although the subject here is not a striped electric wire, a technology has been proposed for checking the condition of a cylindrical object by photographing the peripheral surface with a camera while rotating the object around its axis (see, for example, Patent Document 1). Because a striped electric wire can be considered a cylindrical object, it is conceivable to use the above-mentioned confirmation technology using camera photography to automatically check the reversal of the stripe color order. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-060500 Summary of the Invention [Problem to be solved by the invention]

[0005] As described above, the technology described in Patent Document 1 requires that the object be rotated when photographed by a camera. However, in situations where two striped electric wires are supplied in an array, it is difficult to rotate the striped electric wires around their axial centers, and even with the technology described in Patent Document 1, it is difficult to automatically check whether the order of the stripe colors is reversed.

[0006] Therefore, the present invention focuses on the above-mentioned problems and aims to provide a wire reversal checking device that can automatically check the reversal of the stripe color order for two arranged striped wires. [Means for solving the problem]

[0007] In order to solve the above problem, the wire inversion confirmation device is characterized by comprising: a wire arranging section in which two striped wires having different stripe colors are arranged, the two striped wires having stripes formed on the surface of a wire coating so as to be rotationally symmetrical about an axis of the wire, the two striped wires being arranged in a predetermined stripe color confirmation area so as to extend parallel to each other in a wire arranging direction intersecting with the wire longitudinal direction, and a regular color order of the stripe colors in the wire arranging direction in the stripe color confirmation area is predetermined; a stripe photographing section in which two cameras are arranged to capture within their photographing range the stripes of each of the two striped wires extending in the stripe color confirmation area, the cameras being arranged so as to sandwich a virtual boundary plane extending orthogonal to the wire arranging direction between the two striped wires; and a confirmation section that analyzes images photographed by the two cameras and confirms that the stripe colors of the two striped wires in the stripe color confirmation area are arranged without being reversed with respect to the regular color order in the wire arranging direction. [Effects of the Invention]

[0008] According to the above-described electric wire inversion checking device, it is possible to automatically check whether the order of stripe colors is inverted for two arranged electric wires with stripes. [Brief explanation of the drawings]

[Figure 6] FIG. 6 is an enlarged view of area A12 in FIG. DETAILED DESCRIPTION OF THE INVENTION

[0010] An embodiment of the wire inversion checking device will be described below.

[0011] Fig. 1 is a perspective view showing an electric wire inversion checking device according to one embodiment. Fig. 2 is an enlarged perspective view showing an enlarged stripe color checking area in the electric wire inversion checking device shown in Fig. 1. Fig. 3 is an enlarged plan view of the electric wire inversion checking device shown in Fig. 1, as seen from the direction of arrow V11 in Fig. 1, and Fig. 4 is an enlarged view of area A11 in Fig. 3.

[0012] The wire inversion checking device 1 of this embodiment is a device that checks whether two striped electric wires W1 are arranged in a correct color order without the stripe colors being reversed. The striped electric wire W1 to be checked by this wire inversion checking device 1 is an electric wire on the surface of a wire coating W11, on which a plurality of stripes W12 indicating the intended use by color are formed in rotational symmetry around the wire axis W1a. In this embodiment, each striped electric wire W1 has two stripes W12 formed 180° apart around the wire axis W1a. The wire inversion checking device 1 is used by being disposed on a supply route E13 between a wire payout mechanism E11 and a supply destination E12, which is schematically shown in FIG. 1 . The wire payout mechanism E11 is a mechanism that pays out the striped electric wire W1 in a wire payout direction D12 along the wire longitudinal direction D11. The supply destination E12 is a location that receives the striped electric wire W1 and performs processing such as connecting a connector to the end of the electric wire. The electric wire inversion checking device 1 includes an electric wire placement unit 11, a stripe photographing unit 12, and a checking unit 13.

[0013] The electric wire arrangement section 11 is a section having an appearance of a rectangular plate with a thickness corresponding to the diameter of the striped electric wire W1, in which two striped electric wires W1 with different stripe colors are arranged. In this electric wire arrangement section 11, the two striped electric wires W1 are arranged in a predetermined stripe color confirmation area 11a so as to extend parallel to each other in an electric wire arrangement direction D13 that intersects with the electric wire longitudinal direction D11. At this time, in the electric wire arrangement section 11, a regular color order for the stripe colors in the electric wire arrangement direction D13 in the stripe color confirmation area 11a is predetermined. This regular color order is stored in the confirmation section 13.

[0014] The electric wire placement section 11 includes a bottom plate section 111, a top plate section 112, a guide rib 113, and two electric wire receiving openings 114.

[0015] The bottom plate 111 is a portion on which two striped electric wires W1 extending along both the electric wire longitudinal direction D11 and the electric wire arrangement direction D13 are placed. The top plate 112 is a portion disposed opposite the bottom plate 111 with a gap therebetween according to the thickness of the striped electric wires W1. A photographing window 112a is formed in the top plate 112 at a position corresponding to the stripe color confirmation area 11a so that the two striped electric wires W1 can be seen from a camera 121 (described later).

[0016] The guide rib 113 is a rib that separates two striped electric wires W1 from the electric wire payout mechanism E11 at a position on the electric wire receiving side closer to the electric wire payout mechanism E11 than the stripe color confirmation area 11a. This guide rib 113 is formed upright from the bottom plate portion 111 toward the top plate portion 112 so as to have a rib shape at the position on the electric wire receiving side. The guide rib 113 serves to align the striped electric wires W1 paid out from the electric wire payout mechanism E11 in a branched state in the electric wire arrangement direction D13 and feed them into the stripe color confirmation area 11a.

[0017] The two wire receiving openings 114 are formed in a funnel shape on the wire receiving side of the wire arrangement section 11 where the guide rib 113 is provided, and are portions that receive two striped electric wires W1 one-to-one from the wire payout mechanism E11. The two wire receiving openings 114 are separated in the wire arrangement direction D13 by the guide rib 113. The funnel shape of each wire receiving opening 114 tapers toward the stripe color confirmation area 11a in the wire payout direction D12 from the wire payout mechanism E11. Each wire receiving opening 114 receives each striped electric wire W1 inside its funnel shape, and the funnel shape guides each striped electric wire W1 toward the stripe color confirmation area 11a.

[0018] Next, the stripe photographing unit 12 of the electric wire inversion checking device 1 is a portion where two cameras 121 are arranged, each capturing within its photographing range 121a the stripes W12 of the two striped electric wires W1 extending in the stripe color confirmation area 11a. These two cameras 121 each have a rectangular block-like appearance and are arranged to sandwich an imaginary boundary plane P11 extending between the two striped electric wires W1 in the stripe color confirmation area 11a and perpendicular to the electric wire arrangement direction D13. More specifically, the two cameras 121 are arranged so as to be plane-symmetrical with respect to the imaginary boundary plane P11. More specifically, the two cameras 121 are arranged so that their photographing directions D14 are inclined at an inclination angle θ11 of 45° from the imaginary boundary plane P11 toward the striped electric wires W1 in the stripe color confirmation area 11a. The stripe photographing unit 12 is provided with a camera support unit 122 that supports these two cameras 121 so that they are disposed on either side of the imaginary boundary plane P11 as described above.

[0019] The camera support portion 122 is a sheet metal processed part including a protruding plate portion 122a and a pair of camera support tongues 122b. The protruding plate portion 122a is a rectangular plate-like protruding portion that extends above the stripe color confirmation area 11a in the extension direction D15 of the imaginary boundary plane P11, intersecting with this imaginary boundary plane P11. The pair of camera support tongues 122b extend from both end edges of the protruding plate portion 122a in the electric wire arrangement direction D13 at an inclination angle θ11 corresponding to the imaging direction D14 of each of the two cameras 121, and each supports one of the cameras 121. The pair of camera support tongues 122b are formed by bending up at the inclination angle θ11 at both end edges of the protruding plate portion 122a by sheet metal processing.

[0020] The confirmation unit 13 in the electric wire inversion confirmation device 1 is a computer part that analyzes the images captured by the two cameras 121 and performs the following inversion confirmation process for the two striped electric wires W1 in the stripe color confirmation area 11a. As described above, the confirmation unit 13 stores the regular color order of the stripe colors for the electric wire arrangement direction D13. The inversion confirmation process in the confirmation unit 13 is a process that confirms that the color order of the stripe colors in the two striped electric wires W1 obtained by image analysis is arranged without being inverted from the regular color order that has been stored.

[0021] Here, in the electric wire inversion confirmation device 1 of this embodiment, by using two cameras 121, the following range is secured as the range of the peripheral surface that can be photographed around the electric wire axis W1a for one striped electric wire W1.

[0022] FIG. 5 is a diagram showing the range of the peripheral surface that can be photographed around the axis of each of the two striped electric wires in the stripe color confirmation area using two cameras, and FIG. 6 is an enlarged view of area A12 in FIG. 5.

[0023] As shown in FIGS. 5 and 6 , the range 121a-1 that can be captured by each camera 121 around the wire axis W1a for each of the two striped electric wires W1 is limited to the range on the side where the camera 121 is located. Adding up the ranges 121a-1 for the two cameras 121 enables capturing a two-vehicle capture range 121b exceeding 180° around the wire axis W1a for each striped electric wire W1. In this embodiment, the two cameras 121 are disposed at an inclination angle θ11 of 45° with respect to the virtual boundary plane P11. In this case, the two-vehicle capture range 121b around the wire axis W1a is 266°. By obtaining such a two-vehicle capture range 121b for each striped electric wire W1, each stripe W12 is always within the two-vehicle capture range 121b regardless of the orientation of the striped electric wire W1 around the wire axis W1a.

[0024] According to the electric wire inversion checking device 1 of the embodiment described above, photography is performed by two cameras 121. The two cameras 121 are arranged so that the stripes W12 of two striped electric wires W1 lined up in the stripe color checking area 11a are included in their respective photography ranges 121a and so as to sandwich the imaginary boundary plane P11 between the electric wires. By photographing with such two cameras 121, the stripes W12 of each striped electric wire W1 can be included in the photography range 121b of the two cameras 121, regardless of the orientation of the striped electric wire W1 around the electric wire axis W1a. Then, by photographing with such cameras, it is possible to automatically check for the reversal of the stripe color order of two arranged striped electric wires W1 that are difficult to rotate around the electric wire axis W1a.

[0025] In this embodiment, the electric wire arranging section 11 is arranged on a supply route E13 between the electric wire payout mechanism E11 and a supply destination E12 of the striped electric wire W1. The two striped electric wires W1 from the electric wire payout mechanism E11 pass through the electric wire arranging section 11 so as to pass through the stripe color confirmation area 11a on their way to the supply destination E12. A guide rib 113 formed in a rib shape that separates the two striped electric wires W1 from the electric wire payout mechanism E11 is provided at a position on the electric wire receiving side of the electric wire arranging section 11. The guide rib 113 aligns the two striped electric wires W1 in a state where they are branched in the electric wire arranging direction D13 and feeds them into the stripe color confirmation area 11a. With this configuration, the two striped electric wires W1 passing through the electric wire arranging section 11 can be effectively aligned in a state where they are branched in the electric wire arranging direction D13 on the above-mentioned supply route E13, thereby enabling confirmation of the reversal of the color order of the stripes. Furthermore, since it is possible to check for inversion on the supply route E13 in this way, the two striped electric wires W1 that have been confirmed to be arranged in the correct color order can be properly sent to the supply destination E12.

[0026] In this embodiment, two funnel-shaped wire receiving openings 114 that taper toward the stripe color confirmation area 11a are provided on the wire receiving side of the wire placement section 11. With this configuration, the two striped wires W1 from the wire payout mechanism E11 can be effectively received into the wire placement section 11 through the funnel-shaped wire receiving openings 114 and fed into the stripe color confirmation area 11a.

[0027] In this embodiment, the electric wire placement section 11 includes a bottom plate section 111 and a top plate section 112 that is disposed opposite the bottom plate section 111 and has a photographing window 112a formed therein. According to this configuration, by sandwiching the two striped electric wires W1 between the bottom plate section 111 and the top plate section 112, bending of the striped electric wires W1 in the facing direction of both plate sections can be suppressed, and photographing can be performed with a camera through the photographing window 112a under good photographing conditions.

[0028] Moreover, in this embodiment, the stripe imaging unit 12 includes a camera support unit 122 that supports the two cameras 121. With this configuration, by supporting the two cameras 121 with the camera support unit 122, it is possible to perform camera imaging with the imaging posture of each camera 121 stabilized.

[0029] Furthermore, in this embodiment, the camera support portion 122 includes a protruding plate portion 122a and a pair of camera support tongues 122b. The protruding plate portion 122a is a portion that protrudes in a plate-like shape above the stripe color confirmation area 11a. The pair of camera support tongues 122b extend from both end edges of the protruding plate portion 122a at an inclination angle θ11 corresponding to each shooting direction D14, and each supports the camera 121. With this configuration, the camera support portion 122 can be obtained by inexpensive sheet metal processing, such as bending the pair of camera support tongues 122b at both end edges of the protruding plate portion 122a, compared to joining multiple parts or molding with a resin mold, thereby reducing manufacturing costs.

[0030] In this embodiment, the two cameras 121 are arranged symmetrically with respect to the virtual boundary plane P11. This configuration allows the two cameras 121 to set an equal shooting range 121a for the two striped electric wires W1, thereby obtaining a captured image suitable for checking the reversal of the color order of the stripe colors.

[0031] In this embodiment, each striped electric wire W1 has two stripes W12 formed 180° apart around the electric wire axis W1a. The two cameras 121 are arranged so that their imaging directions D14 are tilted 45° from the imaginary boundary plane P11 and point toward the striped electric wire W1 in the stripe color confirmation area 11a. This configuration is preferable because it allows the stripes W12 of the two striped electric wires W1 to be captured with high accuracy within the imaging range 121b of the two cameras 121.

[0032] The above-described embodiment merely shows a typical example of the electric wire inversion checking device, and the electric wire inversion checking device is not limited to this and can be implemented in various modifications.

[0033] For example, in the above-described embodiment, as an example of the electric wire reversal confirmation device, an electric wire reversal confirmation device 1 is exemplified in which two cameras 121 each having a rectangular block-like appearance are arranged above the electric wire arrangement section 11 having a rectangular plate-like appearance. However, the electric wire reversal confirmation device is not limited to this, and the specific external shapes of the electric wire arrangement section and the cameras arranged above it are not limited to this.

[0034] Furthermore, in the above-described embodiment, an example of an electric wire arrangement section is the electric wire arrangement section 11 that is arranged on the supply route E13 between the electric wire payout mechanism E11 and the supply destination E12 and that is provided with a guide rib 113 at a position on the electric wire receiving side. However, the electric wire arrangement section is not limited to this, and may be one in which, for example, a striped electric wire is statically arranged by an operator, rather than a striped electric wire being paid out from the electric wire payout mechanism to the supply destination. In addition, the electric wire arrangement section may not be provided with any guide rib. However, as described above, by arranging the electric wire arrangement section 11 on the above-described supply route E13 and providing the guide rib 113, the two striped electric wires W1 can be effectively checked for inversion and appropriately fed to the supply destination E12.

[0035] In the above-described embodiment, the electric wire placement section 11 is exemplified as an example of an electric wire placement section, in which two funnel-shaped electric wire receiving openings 114 are provided on the electric wire receiving side. However, the electric wire placement section is not limited to this, and such electric wire receiving openings may not be provided on the electric wire receiving side. However, as described above, by providing two electric wire receiving openings 114, electric wires can be effectively received into the electric wire placement section 11 and sent to the stripe color confirmation area 11a.

[0036] Furthermore, in the above-described embodiment, the electric wire arranging section 11 including the bottom plate 111 and the top plate 112 with the photographing window 112a is exemplified as an example of the electric wire arranging section. However, the electric wire arranging section is not limited to this, and may be formed, for example, in a simple plate shape on the surface of which the striped electric wire is placed. However, as described above, by providing the bottom plate 111 and the top plate 112 with the photographing window 112a, it is possible to perform camera photography under good photographing conditions in which bending of the striped electric wire W1 is suppressed.

[0037] Furthermore, in the above-described embodiment, as an example of a stripe imaging unit, a stripe imaging unit 12 including a camera support part 122 that supports two cameras 121 is given as an example. However, the stripe imaging unit is not limited to this, and as long as imaging is performed with two cameras, the specific installation mode of the two cameras does not matter. However, as described above, when the two cameras 121 are supported by the camera support part 122, camera imaging can be performed with the imaging posture of each camera 121 stabilized.

[0038] Furthermore, in the above-described embodiment, the camera support portion 122 including the protruding plate portion 122a and the pair of camera support tongues 122b is exemplified as an example of the camera support portion. However, the camera support portion is not limited to this, and any specific configuration is possible as long as it supports two cameras. However, as described above, by adopting a configuration including the protruding plate portion 122a and the pair of camera support tongues 122b, the camera support portion 122 can be manufactured using inexpensive sheet metal processing, thereby reducing manufacturing costs.

[0039] Furthermore, in the above-described embodiment, as an example of an electric wire inversion checking device, an electric wire inversion checking device 1 in which two cameras 121 are arranged so as to be plane-symmetrical with respect to the above-described imaginary boundary plane P11 is exemplified. However, the electric wire inversion checking device is not limited to this, and the specific arrangement of the two cameras is not important as long as they are arranged on either side of the imaginary boundary plane. However, as described above, by arranging the two cameras 121 so as to be plane-symmetrical, it is possible to set an equal shooting range 121a and obtain a captured image suitable for checking the reversal of the color order of the stripe colors.

[0040] In the above-described embodiment, as an example of a striped electric wire, a striped electric wire W1 in which two stripes W12 are formed 180° apart around the electric wire axis W1a is exemplified. As an example of a wire inversion checking device for such a striped electric wire W1, a wire inversion checking device 1 is exemplified in which two cameras 121 are arranged with their respective shooting directions D14 inclined 45° from the imaginary boundary plane P11. However, the striped electric wire and the wire inversion checking device are not limited to this. The number of stripes and their arrangement around the electric wire axis are not limited to a specific number or arrangement, as long as multiple stripes are provided rotationally symmetrically around the electric wire axis. Furthermore, the arrangement of the cameras in the wire inversion checking device may be any arrangement, including the inclination angle from the imaginary boundary plane. However, as described above, by separating the stripes W12 by 180° and tilting the camera 121 by 45°, the stripes W12 can be accurately captured within the two-camera-capable range 121b of the two cameras 121.
