Description

Technical Field

[0001] The present invention relates to a wire reverse confirmation device that confirms whether two striped wires are arranged in a state where the stripe colors are not reversed with respect to the normal color order. Background Art

[0002] Conventionally, striped wires have been widely used, where stripes are formed on the surface of the wire coating to indicate the purpose of use by color. Two such striped wires are usually arranged alongside each other and are provided to a connector for connection operations and the like, for example. In this case, in order to ensure that the two striped wires are directed to the correct supply destinations corresponding to various applications, it is desirable that the two striped wires be arranged in such a way that the stripe colors are not reversed with respect to the normal color order corresponding to various applications in the wire arrangement direction. Currently, in most cases, an operator visually confirms the reversal of the color order of the stripe colors when supplying the striped wires. Since this work is often a burden on the operator, it is desirable to be able to automatically perform the reversal confirmation of the color order of the stripe colors.

[0003] Although the object is not a striped wire, a technique has been proposed to inspect the state of the circumferential surface of a cylindrical object by imaging the circumferential surface with a camera while rotating the cylindrical object around its axis (see, for example, Patent Document 1). Since a striped wire can be regarded as a cylindrical object, it is conceivable to use the above-described confirmation technique based on camera imaging to automatically perform the reversal confirmation of the color order of the stripe colors.

[0007] [Technical Problem]

[0008] As described above, in the technique described in Patent Document 1, when imaging with a camera, it is necessary to rotate the object. However, in the case of arranging and supplying two striped wires, it is difficult to rotate the striped wire around the wire axis, and even when using the technique described in Patent Document 1, it is difficult to automatically perform the reversal confirmation of the color order of the stripe colors.

[0009] Therefore, the present invention addresses the above technical problems and aims to provide a wire reverse confirmation device that can automatically perform the reversal confirmation of the color order of the stripe colors for two arranged striped wires.

[0010] [Solution to the Problem]

[0011] To solve the above technical problems, a wire reverse confirmation device is characterized by comprising: a wire arrangement part in which two striped wires with different stripe colors are arranged. Among them, on the surface of the wire coating, a plurality of stripes extending in the wire length direction are formed in a rotationally symmetric manner around the wire axis. The two striped wires are arranged in the wire arrangement direction intersecting the wire length direction in a predetermined stripe color confirmation area to extend along each other, and a normal color order is pre-determined regarding the color order of the stripe colors in the wire arrangement direction in the stripe color confirmation area; a stripe imaging part in which two cameras are arranged. The two cameras are configured to make each stripe of the two striped wires extending in the stripe color confirmation area fall within the imaging range, and a virtual boundary surface (P11) extending orthogonally to the wire arrangement direction (D13) is sandwiched between the two striped wires (W1); and a confirmation part configured to analyze the images captured by the two cameras and confirm that the two striped wires in the stripe color confirmation area are arranged in a manner that the stripe colors in the wire arrangement direction are not reversed relative to the normal color order.

[0012] [Advantages of the Invention]

[0054] The wire reverse confirmation device 1 according to the present embodiment is a device configured to confirm whether two striped wires W1 are arranged in a state where the stripe colors are not reversed with respect to the normal color order. The striped wire W1 as the object to be confirmed by the wire reverse confirmation device 1 is a wire formed in a plurality of strips, and the stripe W12 showing its use in color on the surface of the wire coating W11 is rotationally symmetric about the wire axis W1a. According to the present embodiment, each striped wire W1 has a structure in which two stripes W12 are formed at 180-degree intervals around the wire axis W1a. The wire reverse confirmation device 1 is arranged to be used on the supply path E13 between the wire feeding mechanism E11 and the supply destination E12, as shown in Figure 1 FIG. The wire feeding mechanism E11 is a mechanism for feeding the striped wire W1 in the wire feeding direction D12 along the wire length direction D11. The supply destination E12 is a part for receiving the striped wire W1 and performing processes such as connecting a connector to the wire end, for example. The wire reverse confirmation device 1 includes a wire arrangement unit 11, a stripe imaging unit 12, and a confirmation unit 13.

[0055] The wire arrangement section 11 is a portion having a rectangular plate-like appearance, the thickness of which corresponds to the thickness of the striped wires W1. Two striped wires W1 with different stripe colors are arranged in the wire arrangement section 11. In the wire arrangement section 11, in a predetermined stripe color confirmation area 11a, the two striped wires W1 extending along each other are arranged in a wire arrangement direction D13 intersecting the wire length direction D11. At this time, in the wire arrangement section 11, a normal color sequence is predetermined with respect to the color sequence of the stripe colors in the wire arrangement direction D13 in the stripe color confirmation area 11a. This normal color sequence is stored in the confirmation section 13.

[0056] The wire arrangement section 11 includes a bottom plate portion 111, a top plate portion 112, guide ribs 113, and two wire receiving ports 114.

[0057] The bottom plate portion 111 is a portion that extends in both the wire length direction D11 and the wire arrangement direction D13 and on which the two striped wires W1 are placed. The top plate portion 112 is a portion that faces the bottom plate portion 111 at an interval corresponding to the thickness of the striped wire W1. In the top plate portion 112, an imaging window 112a is formed at a position corresponding to the stripe color confirmation area 11a so that the two striped wires W1 can be observed from a camera 121 described below.

[0058] The guide ribs 113 are ribs for separating the space between the two striped wires W1 from the wire feeding mechanism E11 at a position on the wire receiving side closer to the wire feeding mechanism E11 than the stripe color confirmation area 11a. The guide ribs 113 are formed to stand upright from the bottom plate portion 111 toward the top plate portion 112, so as to be rib-shaped at the position on the wire receiving side. Thus, the guide ribs 113 are responsible for arranging the striped wires W1 fed from the wire feeding mechanism E11 in a branched state in the wire arrangement direction D13 and then transporting them to the stripe color confirmation area 11a.

[0059] The two wire receiving ports 114 are portions respectively formed in a funnel shape at the wire receiving side of the wire arrangement section 11 where the guide ribs 113 are provided to receive the two striped wires W1 from the wire feeding mechanism E11 in a one-to-one correspondence. The two wire receiving ports 114 are separated by the guide ribs 113 in the wire arrangement direction D13. The funnel shape of each wire receiving port 114 is a shape that gradually tapers as it approaches the stripe color confirmation area 11a from the wire feeding mechanism E11 along the wire feeding direction D12. Each wire receiving port 114 receives each striped wire W1 into the inside of the funnel shape and then guides each striped wire W1 toward the stripe color confirmation area 11a using the funnel shape.

[0060] Next, the stripe imaging unit 12 in the wire reversal confirmation device 1 is a part where two cameras 121 are arranged. The two cameras 121 are used to image each stripe W12 of the two stripe wires W1 extending in the stripe color confirmation area 11a into the imaging area 121a. Both of these two cameras 121 have a rectangular block-like appearance, and they are arranged to sandwich the virtual boundary surface P11 that extends orthogonally to the wire arrangement direction D13 between the two stripe wires W1 in the stripe color confirmation area 11a. More specifically, the two cameras 121 are arranged to be symmetric with respect to the plane of the virtual boundary surface P11. More specifically, the imaging directions D14 of the two cameras 121 are inclined at an angle θ11 of 45 degrees from the virtual boundary surface P11 to face the stripe wires W1 in the stripe color confirmation area 11a. Then, the stripe imaging unit 12 includes a camera support part 122 such that, as described above, the two cameras 121 are arranged to sandwich the virtual boundary surface P11.

[0061] The camera support part 122 is a metal sheet processing component, which includes a protruding plate part 122a and a pair of camera support tongues 122b. The protruding plate part 122a is a part that protrudes in a rectangular plate shape and extends in the extending direction D15 of the virtual boundary surface P11 upward toward the stripe color confirmation area 11a in an intersecting manner with the virtual boundary surface P11. The pair of camera support tongues 122b are parts that respectively extend from both end edges of the protruding plate part 122a in the wire arrangement direction D13 at an inclination angle θ11 corresponding to the imaging direction D14 of each of the two cameras 121 to support the two cameras 121 in a one-to-one correspondence. The pair of camera support tongues 122b are parts that are folded up at both end edges of the protruding plate part 122a at the above inclination angle θ11 by metal sheet processing.

[0062] Then, the confirmation unit 13 in the wire reversal confirmation device 1 is a computer unit that analyzes the images captured by the two cameras 121 and performs the following-described reversal confirmation process on the two stripe wires W1 in the stripe color confirmation area 11a. As described above, in the confirmation unit 13, the normal color order of the stripe colors in the wire arrangement direction D13 is stored therein. The reversal confirmation process in the confirmation unit 13 is a process of confirming whether the color order of the stripe colors in the two stripe wires W1 obtained by image analysis is not reversed with respect to the stored normal color order.

[0063] Here, regarding the wire reversal confirmation device 1 according to the present embodiment, by using two cameras 121, for one stripe wire W1, as the range that can image around the wire axis W1a, the following range is ensured.

[0064] Figure 5It is a view showing the range of the circumferential surface that can be imaged around the wire axis by using two cameras for each of the two striped wires in the stripe color confirmation area. Figure 6 is Figure 5 an enlarged view of area A12 in

[0065] As Figure 5 and Figure 6 shown, the imaging range 121a-1 of each of the two striped wires W1 by each camera 121 around the wire axis W1a is limited to the range on the arrangement side of each camera 121. By superimposing these imaging ranges 121a-1 of the two cameras 121, for one striped wire W1, the imaging within the two-camera imaging range 121b can exceed 180 degrees around the wire axis W1a. According to this embodiment, the two cameras 121 are arranged at an inclination angle θ11 of 45 degrees with respect to the above-mentioned virtual boundary surface P11, and in this case, the two-camera imaging range 121b around the wire axis W1a becomes 266 degrees. By achieving such a two-camera imaging range 121b for one striped wire W1, regardless of the attitude taken by the striped wire W1 around the wire axis W1a, one stripe W12 will always fall within the two-camera imaging range 121b.

[0066] According to the above wire reversal confirmation device 1, imaging is performed by two cameras 121. The two cameras 121 are arranged to sandwich the virtual boundary surface P11 between the wires and accommodate the stripes W12 of the two striped wires W1 arranged in the stripe color confirmation area 11a within their respective imaging ranges 121a. By using these two cameras 121 for imaging, regardless of the attitude taken by the striped wire W1 around the wire axis W1a, the stripes W12 of each striped wire W1 can fall within the two-camera imaging range 121b of the two cameras. In addition, through this camera imaging, it is possible to automatically perform the reversal confirmation of the color order of the stripes of the two arranged striped wires W1 that are difficult to rotate around the wire axis W1a.

[0067] Here, according to this embodiment, the wire arrangement unit 11 is disposed on the supply path E13 between the wire feeding mechanism E11 of the striped wire W1 and the supply destination E12. Two striped wires W1 from the wire feeding mechanism E11 pass through the wire arrangement unit 11 and pass through the stripe color confirmation area 11a on the way to the supply destination E12. Then, at the position on the wire receiving side in the wire arrangement unit 11, a guide rib 113 formed in a rib shape is provided to space apart the two striped wires W1 from the wire feeding mechanism E11. The guide rib 113 arranges the two striped wires W1 in a branched state in the wire arrangement direction D13 to transport them to the stripe color confirmation area 11a. Due to this configuration, on the above supply path E13, the two striped wires W1 passing through the wire arrangement unit 11 can be effectively arranged in a branched state in the wire arrangement direction D13 for reverse confirmation of the stripe color. In addition, since the reverse confirmation can be performed on the supply path E13 in this way, the two striped wires W1 that have been confirmed to be arranged in the normal color order can be appropriately transported to the supply destination E12.

[0068] In addition, according to this embodiment, at the wire receiving side in the wire arrangement unit 11, two wire receiving ports 114 formed in a funnel shape are provided, and the funnel shape gradually tapers as it approaches the stripe color confirmation area 11a. According to this configuration, the two striped wires W1 from the wire feeding mechanism E11 can be effectively received in the wire arrangement unit 11 via the funnel-shaped wire receiving ports 114 and then transported to the stripe color confirmation area 11a.

[0069] In addition, according to this embodiment, the wire arrangement unit 11 includes a bottom plate portion 111 and a top plate portion 112, and the top plate portion 112 is provided to face the bottom plate portion 111 and an imaging window 112a is formed in the top plate portion 112. According to this structure, by sandwiching the two striped wires W1 between the bottom plate portion 111 and the top plate portion 112, any bending of the striped wires W1 in the opposing direction of the two plate portions can be suppressed, and camera imaging can be performed via the imaging window 112a under such good imaging conditions.

[0070] In addition, according to this embodiment, the stripe imaging unit 12 includes a camera support portion 122 for supporting two cameras 121. According to this configuration, by supporting the two cameras 121 with the camera support portion 122, the imaging postures of the respective cameras 121 can be stabilized for camera imaging.

[0071] In addition, according to the present 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 upward in a plate shape toward the stripe color confirmation region 11a. The pair of camera support tongues 122b are portions where each camera support tongue 122b extends from both end edges of the protruding plate portion 122a at an inclination angle θ11 corresponding to each imaging direction D14 and supports the camera 121 respectively. According to this configuration, the camera support portion 122 can be obtained by processing a metal sheet, which is cheaper than joining multiple parts or resin molding, such as by folding up a pair of camera support tongues 122b at both end edges of the protruding plate portion 122a, thereby reducing the manufacturing cost.

[0072] In addition, according to the present embodiment, the two cameras 121 are arranged to be plane-symmetrical with respect to the above-described virtual boundary surface P11. According to this configuration, a uniform imaging range 121a can be set for the two stripe wires W1 by the two cameras 121 to obtain a captured image suitable for reverse confirmation of the color sequence of the stripe color.

[0073] In addition, according to the present embodiment, each stripe wire W1 is formed with two stripes W12 that are spaced 180 degrees from each other around the wire axis W1a. The two cameras 121 are arranged such that each imaging direction D14 is inclined 45 degrees from the virtual boundary surface P11 to face the stripe wire W1 in the stripe color confirmation region 11a. According to this configuration, the stripes W12 of the two stripe wires W1 accurately fall within the two-camera imaging ranges 121b of the two cameras 121, which is therefore preferable.

[0074] In addition, the above-described embodiment is only used to illustrate a representative embodiment of the wire reverse confirmation device. The wire reverse confirmation device is not limited thereto, and various modifications can be appropriately implemented.

[0075] For example, according to the above-described embodiment, as an example of the wire reverse confirmation device, the wire reverse confirmation device 1 is shown as an example in which two cameras 121 each having a rectangular block-like appearance are arranged above a wire arrangement portion 11 having a rectangular plate-like appearance. However, the wire arrangement portion is not limited thereto, and the specific shapes and appearances of the wire arrangement portion and the cameras provided above it are not particularly limited.

[0076] In addition, according to the above-described embodiment, as an example of the wire arrangement unit, the wire arrangement unit 11 is shown as an example in which the guide ribs 113 are provided at the wire receiving side and arranged on the supply path E13 between the wire feeding mechanism E11 and the supply destination E12. However, the wire arrangement unit is not limited thereto, and for example, instead of the striped wire fed from the wire feeding mechanism to the supply destination, the striped wire may be statically arranged by the operator. Thus, no guide ribs may be provided in the wire arrangement unit. However, as described above, by arranging the wire arrangement unit 11 on the above-described supply path E13 and providing the guide ribs 113, two striped wires W1 can be effectively provided for effective reverse confirmation and transported to the supply destination E12.

[0077] In addition, according to the above-described embodiment, as an example of the wire arrangement unit, the wire arrangement unit 11 is shown in which two wire receiving ports 114 formed in a funnel shape are provided on the wire receiving side. However, the wire arrangement unit is not limited thereto, and such wire receiving ports may not be provided on the wire receiving side. However, by providing such two wire receiving ports 114, as described above, the striped wire can be effectively received in the wire arrangement unit 11 and transported to the stripe color confirmation area 11a.

[0078] In addition, according to the above-described embodiment, as an example of the wire arrangement unit, the wire arrangement unit 11 including the bottom plate portion 111 and the top plate portion 112 having the imaging window 112a is shown. However, the wire arrangement unit is not limited thereto, and it may be simply configured in a plate shape, and the striped wire is placed on its surface. However, as described above, by providing the bottom plate portion 111 and the top plate portion 112 having the imaging window 112a, camera imaging can be performed under good imaging conditions that suppress the bending of the striped wire W1.

[0079] In addition, according to the above-described embodiment, as an example of the stripe imaging unit, the stripe imaging unit 12 including the camera support portion 122 for supporting the two cameras 121 is shown. However, the stripe imaging unit is not limited thereto, and there is no particular limitation on the specific arrangement of the two cameras, as long as the two cameras are used for imaging. However, as described above, according to the embodiment in which the two cameras 121 are supported by the camera support portion 122, the imaging posture of each camera 121 can be stabilized to perform camera imaging.

[0080] In addition, according to the above-described embodiment, as an example of the camera support portion, the camera support portion 122 including the protruding plate portion 122a and a pair of camera support tongues 122b is shown. However, the camera support portion is not limited thereto, and the specific configuration is not particularly limited as long as there is a configuration for supporting two cameras. However, as described above, by adopting the configuration including the protruding plate portion 122a and a pair of camera support tongues 122b, the camera support portion 122 can be manufactured by processing a cheap metal sheet, thereby reducing the manufacturing cost.

[0081] In addition, according to the above-described embodiment, as an example of the wire reversal confirmation device, the wire reversal confirmation device 1 in which two cameras 121 are arranged symmetrically with respect to the above-described virtual boundary surface P11 plane is shown. However, the wire reversal confirmation device is not limited thereto, and the specific arrangement of the two cameras is not particularly limited as long as there is an arrangement for sandwiching the virtual boundary surface. However, as described above, by arranging the two cameras 121 in a plane-symmetrical manner, a uniform imaging range 121a can be set, and a captured image suitable for the reversal confirmation of the color sequence of the stripe colors can be obtained.

[0082] In addition, according to the above-described embodiment, as an example of the striped wire, the striped wire W1 in which two stripes W12 are formed to be separated from each other by 180 degrees around the wire axis W1a is shown. Then, as an example of the wire reversal confirmation device that uses such a striped wire W1 as the object to be processed, the wire reversal confirmation device 1 in which two cameras 121 are arranged such that each imaging direction D14 is inclined 45 degrees from the virtual boundary surface P11 is shown. However, the striped wire and the wire reversal confirmation device are not limited thereto, and regarding the number of stripes and the arrangement around the wire axis, as long as a configuration in which a plurality of stripes are rotationally symmetrically arranged around the wire axis is adopted, the specific number and arrangement are not particularly limited. In addition, any arrangement including the inclination angle from the virtual boundary surface can be adopted as the arrangement of the cameras in the wire reversal confirmation device. However, as described above, by separating the stripes W12 by 180 degrees and inclining the cameras 121 by 45 degrees, the stripes W12 can be accurately positioned within the two-camera imaging ranges 121b corresponding to the two cameras 121.
