Description

[Technical field]

[0001] The present invention relates to a rotating device. [Background technology]

[0002] In order to arrange the cables laid on the peripheral side of a rotating plate, a technique is known in which a single Cablebear (registered trademark) with multiple links connected thereto is arranged so as to be wrapped around a portion (half of the circumference) of the peripheral side of the rotating plate (for example, Patent Document 1).

[0003] [Patent Document 1] JP 2004-50780 A Summary of the Invention [Problem to be solved by the invention]

[0004] When increasing the number of cables laid on the circumferential side of the turntable, it is necessary to increase the number of cables stored in the cable bear wrapped around the circumferential side of the turntable, or to increase the number of cable bears or the size of the cable bear. However, since there is a limit to the number of cables that can be stored in one cable bear, it may be necessary to increase the number of cable bears or the size of the cable bear. In such cases, this can be addressed by increasing the number of cable bears wound around the circumferential side of the turntable in the direction of the rotation axis, or by increasing their size, but it is necessary to extend the turntable in the direction of the rotation axis to secure space to install multiple cable bears.

[0005] An object of the present invention is to increase the number of cables installed on a rotating disk, the peripheral side of which is covered with cables, without stretching the rotating disk in the direction of the rotation axis. [Means for solving the problem]

[0006] The present invention, which was completed with this object in mind, is a rotating device comprising: a rotating disk having a plurality of cables connected to different positions on its peripheral surface and rotatable in a circumferential direction; and a plurality of cable guide devices for guiding the cables, each of which stores at least a portion of the cables in a plurality of flexibly connected links, with one end fixed to the peripheral surface and the other end fixed to a position independent of the rotation of the rotating disk, and which are positioned so as not to overlap in the direction of the rotation axis of the rotating disk, wherein the plurality of cable guide devices are wound or unwound around the peripheral surface in accordance with the circumferential rotation of the rotating disk. Here, the plurality of cable guide devices may be arranged at positions where they do not interfere with each other when wound around the peripheral side surface and when unwound. In addition, the multiple cable guide devices may be configured so that the length in the connection direction of the link is longer for one where the position at which the other end is fixed is located on the ground side of the turntable than for one where the position is located on the top side of the turntable in the vertical direction. In addition, the multiple cable guide devices may be configured such that when one end is sometimes positioned in a direction from 2 o'clock to 4 o'clock relative to the radial center of the turntable, the other end is not fixed in a direction from 8 o'clock to 10 o'clock relative to the radial center of the turntable, and when one end is sometimes positioned in a direction from 8 o'clock to 10 o'clock relative to the radial center of the turntable, the other end is not fixed in a direction from 2 o'clock to 4 o'clock relative to the radial center of the turntable. In addition, a first cable guiding device and a second cable guiding device may be arranged as the multiple cable guiding devices, and one end of the first cable guiding device and one end of the second cable guiding device may be arranged in symmetrical positions with respect to the center of rotation of the turntable. The cable guide may further include a locking portion that is arranged at a position independent of the rotation of the rotating disk and that locks each of the plurality of cable guide devices that slacken toward the outside in the radial direction of the rotating disk. The other end may be fixed to the engaging portion. Effect of the Invention

[0007] According to the present invention, the number of cables can be increased without extending the rotating disk, on whose peripheral surface the cables are laid, in the direction of the rotation axis. [Brief description of the drawings]

[Figure 6] FIG. 4 is a diagram showing an example of the external configuration of a rotation device according to a second embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. <First embodiment> (Configuration of Rotating Device) 1 and 2 are diagrams showing an example of the external configuration of a rotating device 1 according to a first embodiment of the present invention. Fig. 1 shows a state in which cable guide devices 12 and 13 are fully wound around a rotating disk 11, and Fig. 2 shows a state in which cable guide devices 12 and 13 are fully unwound. The rotating device 1 shown in Figures 1 and 2 is configured to include a rotating disk 11, a cable guiding device 12 as a first cable guiding device, a cable guiding device 13 as a second cable guiding device, first engagement portions 14 and 15, and second engagement portions 16 and 17.

[0010] The rotating disk 11 has a peripheral side surface 111 and is a rotating disk that can rotate in a circumferential direction. The rotating disk 11 can rotate in a circumferential direction and turn over, for example, 180 degrees or less. A first cable 31 and a second cable 32, shown by dashed lines, are connected to the peripheral side surface 111 of the rotating disk 11 at different positions.

[0011] The cable guide device 12 is a member that guides the first cable 31 by storing at least a part of the first cable 31 in a plurality of flexibly connected links 121, and is configured, for example, as a so-called cable bear that enables the protection and guidance of a movable cable. One end of the cable guide device 12 is fixed to the peripheral side surface 111 of the turntable 11, and the other end is fixed to a surface 141 near the left end in the left-right direction of the first locking part 14, which is in a position independent of the rotation of the turntable 11. The cable guide device 12 has a fixing part 122 for fixing one end to the peripheral side surface 111 of the turntable 11, and a fixing part 123 for fixing the other end to the surface 141 of the first locking part 14. The method for fixing one end of the cable guiding device 12 to the peripheral side surface 111 of the rotating disk 11 by the fixing portion 122, and the method for fixing the other end of the cable guiding device 12 to the surface 141 of the first engagement portion 14 by the fixing portion 123 are not particularly limited, and may be fixed, for example, by screws, welding, etc.

[0012] The cable guide device 12 is bent in accordance with the rotation of the rotating disk 11 in the circumferential direction, and is wound or unwound around the circumferential side surface 111 of the rotating disk 11. As described above, FIG. 1 shows a state in which the cable guide device 12 is wound most around the circumferential side surface 111 of the rotating disk 11. Therefore, when the rotating disk 11 rotates to the right in the circumferential direction (rotates clockwise) from the state shown in FIG. 1, the cable guide device 12 bends in accordance with the rotation and is unwound while moving away from the circumferential side surface 111, finally reaching the state shown in FIG. 2. Also, when the rotating disk 11 rotates reversely to the left in the circumferential direction (rotates counterclockwise) from the state shown in FIG. 2, the cable guide device 12 finally reaches the state shown in FIG. 1.

[0013] The cable guide device 12 has a portion wound around the circumferential side surface 111 of the turntable 11, and a portion in contact with the surface 141 of the first locking portion 14. Furthermore, the cable guide device 12 has a portion bent so as to bulge toward the right side in the circumferential direction of the turntable 11 in order to provide some slack in the length of the link 121 in the connecting direction. Specifically, for example, the overall length of the cable guide device 12 is provided with some slack so that it is about 5% to 20% longer than when this "portion bent so as to bulge" is not formed (i.e., when no slack is provided).

[0014] When the cable guide device 12 is reversed, it tends to slacken toward the ground in the vertical direction due to its own weight. If the cable guide device 12 slackens too much toward the ground, it may interfere with other components. For this reason, the length in the connecting direction of the link 121 of the cable guide device 12 is designed to be a length that will not interfere with other components even if it slackens toward the ground due to its own weight.

[0015] The cable guide device 13 is a member that guides the second cable 32 by storing at least a part of the second cable 32 in a plurality of flexibly connected links 131, and is configured, for example, as a so-called cable bear that enables the protection and guidance of a movable cable. One end of the cable guide device 13 is fixed to the peripheral side surface 111 of the turntable 11, and the other end is fixed to a surface 151 near the right end in the left-right direction of the first locking part 15, which is in a position independent of the rotation of the turntable 11. The cable guide device 13 has a fixing part 132 for fixing one end to the peripheral side surface 111 of the turntable 11, and a fixing part 133 for fixing the other end to the surface 151 of the first locking part 15. The method for fixing one end of the cable guiding device 13 to the peripheral side surface 111 of the rotating disk 11 by the fixing portion 132, and the method for fixing the other end of the cable guiding device 13 to the surface 151 of the first engagement portion 15 by the fixing portion 133 are not particularly limited, and may be fixed by, for example, screws, welding, etc.

[0016] The cable guide device 13 is bent in accordance with the rotation of the rotating disk 11 in the circumferential direction, and is wound or unwound on the circumferential side surface 111 of the rotating disk 11. As described above, FIG. 1 shows a state in which the cable guide device 13 is wound most around the circumferential side surface 111 of the rotating disk 11. Therefore, when the rotating disk 11 rotates to the right in the circumferential direction (rotates clockwise) from the state shown in FIG. 1, the cable guide device 13 bends in accordance with the rotation and is unwound while moving away from the circumferential side surface 111, finally reaching the state shown in FIG. 2. Also, when the rotating disk 11 is reversed to the left in the circumferential direction (rotates counterclockwise) from the state shown in FIG. 2, the cable guide device 13 finally reaches the state shown in FIG. 1.

[0017] The cable guide device 13 has a portion wound around the circumferential side surface 111 of the turntable 11, and a portion in contact with the surface 151 of the first locking portion 15. Furthermore, the cable guide device 13 has a portion bent so as to bulge toward the right side in the circumferential direction of the turntable 11 in order to provide some slack in the length of the link 131 in the connecting direction. Specifically, for example, the cable guide device 13 is provided with a slack such that the overall length is about 5% to 20% longer than when this "portion bent so as to bulge" is not formed (i.e., when no slack is provided).

[0018] When the cable guide device 13 is reversed, it tends to slacken toward the ground in the vertical direction due to its own weight. If the cable guide device 13 slackens too much toward the ground, it may interfere with other components. For this reason, the length in the connecting direction of the link 131 of the cable guide device 13 is designed to be a length that will not interfere with other components even if it slackens toward the ground due to its own weight.

[0019] The cable guide devices 12 and 13 shown in Fig. 1 and Fig. 2 have the same length in the link connection direction. Moreover, one end of each of the cable guide devices 12 and 13 is fixed to different positions on the peripheral side surface 111 of the rotating plate 11. That is, the fixed portion 122 of the cable guide device 12 and the fixed portion 132 of the cable guide device 13 are fixed to different positions on the peripheral side surface 111 of the rotating plate 11. Moreover, in the example of Fig. 1 and Fig. 2, the fixed portion 122 of the cable guide device 12 and the fixed portion 132 of the cable guide device 13 are disposed at positions symmetrical with respect to the rotation center of the rotating plate 11.

[0020] Furthermore, cable guide device 12 and cable guide device 13 are disposed in positions where they do not interfere with each other when wound around circumferential side surface 111 of turntable 11 and when unwound. Furthermore, cable guide device 12 and cable guide device 13 are disposed in positions where they do not overlap in the direction of the rotation axis of turntable 11 (i.e., on the same circumference). In other words, cable guide device 12 and cable guide device 13 are not disposed so as to be lined up in the direction of the rotation axis of turntable 11.

[0021] In addition, in each of the cable guide devices 12 and 13, the position on the peripheral side surface 111 where one end is fixed and the position where the other end is fixed to the surface 141 of the first locking portion 14 or the surface 151 of the first locking portion 15 are not limited to the examples shown in FIG. 1 and FIG. 2. However, when one end of each of the cable guide devices 12 and 13 may be disposed in the direction from 2 o'clock to 4 o'clock with respect to the center in the radial direction of the rotating disk 11, the other end of each of the cable guide devices 12 and 13 is not fixed in the direction from 8 o'clock to 10 o'clock with respect to the center in the radial direction of the rotating disk 11. That is, in the cable guide device 12, when the fixing portion 122 is disposed in the direction from 2 o'clock to 4 o'clock with respect to the center in the radial direction of the rotating disk 11, for example, the fixing portion 123 is not fixed in the direction from 8 o'clock to 10 o'clock with respect to the center in the radial direction of the rotating disk 11. Similarly, in the cable guide device 13, when the fixing portion 132 is disposed in the direction from 2 o'clock to 4 o'clock with respect to the center in the radial direction of the rotating disk 11, the fixing portion 133 is not fixed in the direction from 8 o'clock to 10 o'clock with respect to the center in the radial direction of the rotating disk 11.

[0022] Furthermore, when one end of each of the cable guide devices 12 and 13 may be disposed in the direction from 8 o'clock to 10 o'clock with respect to the center in the radial direction of the rotating disk 11, the other end of each of the cable guide devices 12 and 13 is not fixed in the direction from 2 o'clock to 4 o'clock with respect to the center in the radial direction of the rotating disk 11. That is, when the fixing part 122 of the cable guide device 12 may be disposed in the direction from 8 o'clock to 10 o'clock with respect to the center in the radial direction of the rotating disk 11, for example, the fixing part 123 of the cable guide device 12 is not fixed in the direction from 2 o'clock to 4 o'clock with respect to the center in the radial direction of the rotating disk 11. Similarly, when the fixing part 132 of the cable guide device 13 may be disposed in the direction from 8 o'clock to 10 o'clock with respect to the center in the radial direction of the rotating disk 11, the fixing part 133 of the cable guide device 13 is not fixed in the direction from 2 o'clock to 4 o'clock with respect to the center in the radial direction of the rotating disk 11.

[0023] The first locking portion 14 is an arc-shaped member fixed at a position on the radial outside of the rotating disk 11 and independent of the rotation of the rotating disk 11. The first locking portion 14 locks the cable guide device 12 so as not to slacken toward the radial outside of the rotating disk 11 when the cable guide device 12 is unwound and separated from the rotating disk 11.

[0024] The first locking portion 15 is an arc-shaped member fixed at a position on the radial outside of the rotating disk 11 and independent of the rotation of the rotating disk 11. The first locking portion 15 locks the cable guide device 13 so as not to slacken toward the radial outside of the rotating disk 11 when the cable guide device 13 is unwound and separated from the rotating disk 11.

[0025] The second locking portion 16 is an arc-shaped member fixed at a position that is radially outside the rotating disk 11 and independent of the rotation of the rotating disk 11. The second locking portion 16 is disposed radially inside the rotating disk 11 relative to the first locking portion 14. The second locking portion 16 locks the cable guide device 12 wound around the rotating disk 11 so as to prevent it from loosening toward the radially outside of the rotating disk 11.

[0026] The second locking portion 17 is an arc-shaped member disposed on the radially outer side of the rotating disk 11 and at a position independent of the rotation of the rotating disk 11. The second locking portion 17 is disposed on the radially inner side of the rotating disk 11 than the first locking portion 15. The second locking portion 17 locks the cable guide device 13 wound around the rotating disk 11 so as to prevent it from loosening toward the radially outer side of the rotating disk 11.

[0027] (Link structure) 3A to 3C are diagrams showing an example of the external configuration of the link 121 constituting the cable guide device 12. (A) is a front view of the link 121. (B) is a side view of the link 121. (C) is a plan view of the link 121. The front view shown in (A) is a diagram showing the state of the link 121 when viewed from the direction of the arrow 503 shown in (B) and (C). The side view shown in (B) is a diagram showing the state of the link 121 when viewed from the direction of the arrow 502 shown in (A) and (C). The plan view shown in (C) is a diagram showing the state of the link 121 when viewed from the direction of the arrow 501 shown in (A) and (B).

[0028] 3(A) to 3(C), the link 121 is configured with a frame portion 211 having connecting holes 212 and 213. The frame portion 211 is a member that forms a space 214 capable of accommodating at least a portion of the first cable 31 shown by a dashed line, and guides the first cable 31. The connecting holes 212 and 213 are holes provided in two places on the frame portion 211. By aligning the connecting hole 212 of one link 121 with the connecting hole 213 of another link 121 and rotatably fixing them by crimping or the like, a bendable cable guide device 12 in which a plurality of links 121 are connected can be formed.

[0029] 3(A) to (C) and the above-mentioned FIGS. 1 and 2 each show a schematic representation of a single first cable 31, but there may be multiple first cables 31. The number of first cables 31 is not particularly limited as long as it fits within space 214 formed by frame 211 of link 121. When there are multiple first cables 31, multiple cables having the same diameter may be grouped together to form first cable 31, or multiple cables having different diameters may be grouped together to form first cable 31.

[0030] In addition, the link 131 constituting the cable guide device 13 shown in the above-mentioned FIG. 1 and FIG. 2 also has a configuration similar to that of the link 121 shown in FIG. 3(A) to (C). That is, the link 131 is configured with a frame portion and a connection hole similar to the frame portion 211, the connection hole 212, and the connection hole 213 shown in FIG. 3(A) to (C). In addition, the second cable 32 shown in each of FIG. 1 and FIG. 2 is also drawn as one cable, but the second cable 32 may be a plurality of cables. In addition, the number of the second cables 32 is not particularly limited, and may be the number that fits in the space formed by the frame portion of the link 131. When there are a plurality of second cables 32, the second cable 32 may be formed by bundling a plurality of cables having the same diameter size, or the second cable 32 may be formed by bundling a plurality of cables having different diameter sizes.

[0031] (Modification) 4(A) and (B) are partial views showing a modified example of the rotating device 1 according to the first embodiment. As a modified example, Fig. 4(A) and (B) show a specific example in which each of the first cable guide device and the second cable guide device is arranged in parallel in the direction of the rotation axis of the rotating disk 11. In Fig. 4(A) and (B), the rotating device 1 is used as a part of a rotating mold of a molding machine that is composed of a movable mold, a fixed mold, and a rotating mold, as a specific application example.

[0032] Depending on the length of the rotating disk 11 of the rotating device 1 in the rotation axis direction and the size of the cable guide device, a plurality of cable guide devices to be wound around the peripheral side surface 111 of the rotating disk 11 may be arranged in parallel in the rotation axis direction. For example, FIG. 4(A) shows an example in which two first cable guide devices (cable guide devices 22 and 23) are arranged in parallel in the rotation axis direction of the rotating disk 11. FIG. 4(A) shows a state in which two first cable guide devices (cable guide devices 22 and 23) are wound around the rotating disk 11 to the maximum. FIG. 4(B) shows an example in which two second cable guide devices (cable guide devices 24 and 25) are arranged in parallel in the rotation axis direction of the rotating disk 11. FIG. 4(B) shows a state in which two second cable guide devices (cable guide devices 24 and 25) are wound around the rotating disk 11 to the maximum.

[0033] The rotating device 1 shown in Figures 4(A) and (B) is configured to include a rotating disk 11 having a peripheral side surface 111 and capable of rotating in a circumferential direction, two first cable guide devices (cable guide devices 22 and 23), two second cable guide devices (cable guide devices 24 and 25), first locking portions 14 and 15, second locking portions 16 and 17, and a mounting disk 18 for connecting a movable mold or a fixed mold (not shown) to a rotating mold. In the rotating device 1 shown in Figures 4(A) and (B), the rotating disk 11, the first locking portions 14 and 15, and the second locking portions 16 and 17 are the same as those shown in Figures 1 and 2, and therefore their explanations are omitted. Also, the first locking portion 14 shown in Figure 4(A) is omitted in Figure 4(B).

[0034] Each of the two first cable guide devices (cable guide devices 22 and 23) is a member that guides the first cable 31 (see Figs. 1 and 2) by storing at least a portion of the first cable 31, and is, for example, configured as a so-called cable bear that enables protection and guidance of a movable cable. Each of the two first cable guide devices (cable guide devices 22 and 23) has one end fixed to the peripheral side surface 111 of the turntable 11, and the other end fixed to a surface 141 near the left end in the left-right direction of the first locking portion 14. Of these, the cable guide device 22 has a fixing portion 222 for fixing one end to the peripheral side surface 111 of the turntable 11, and a fixing portion 223 for fixing the other end to the surface 141 of the first locking portion 14. Moreover, the cable guide device 23 has a fixing portion 232 for fixing one end to the peripheral side surface 111 of the rotating disk 11 and a fixing portion 233 for fixing the other end to the surface 141 of the first engagement portion 14.

[0035] The two first cable guide devices (cable guide devices 22 and 23) bend in accordance with the circumferential rotation of the turntable 11, and are thereby wound or unwound around the circumferential side surface 111 of the turntable 11. As described above, FIG. 4(A) shows a state in which the two first cable guide devices (cable guide devices 22 and 23) are wound most around the circumferential side surface 111 of the turntable 11. Therefore, when the turntable 11 rotates to the right in the circumferential direction (rotates clockwise) from the state shown in FIG. 4(A), the two first cable guide devices (cable guide devices 22 and 23) bend in accordance with the rotation, and are unwound while moving away from the circumferential side surface 111.

[0036] Each of the two second cable guide devices (cable guide devices 24 and 25) is a member that guides the second cable 32 (see Figs. 1 and 2) by storing at least a portion of the second cable 32, and is, for example, configured as a so-called cable bear that enables the protection and guidance of a movable cable. Each of the two second cable guide devices (cable guide devices 24 and 25) has one end fixed to the peripheral side surface 111 of the turntable 11, and the other end fixed to a surface 151 near the right end in the left-right direction of the first locking portion 15. Of these, the cable guide device 24 has a fixing portion 242 for fixing one end to the peripheral side surface 111 of the turntable 11 and a fixing portion 243 for fixing the other end to the surface 151 of the first locking portion 15. Moreover, the cable guide device 25 has a fixing portion 252 for fixing one end to the peripheral side surface 111 of the rotating disk 11 and a fixing portion 253 for fixing the other end to the surface 151 of the first engagement portion 15.

[0037] The two second cable guide devices (cable guide devices 24 and 25) bend in accordance with the circumferential rotation of the turntable 11, and are thereby wound or unwound around the circumferential side surface 111 of the turntable 11. As described above, FIG. 4(B) shows a state in which the two second cable guide devices (cable guide devices 24 and 25) are wound most around the circumferential side surface 111 of the turntable 11. Therefore, when the turntable 11 rotates to the right in the circumferential direction (rotates clockwise) from the state shown in FIG. 4(B), the two second cable guide devices (cable guide devices 24 and 25) bend in accordance with the rotation, and are unwound while moving away from the circumferential side surface 111.

[0038] In summary, the rotating device 1 according to the first embodiment of the present invention only needs to have the following configuration, and can take on a variety of different embodiments. That is, the rotating device 1 according to the first embodiment includes a rotating disk 11 to which a plurality of cables (e.g., a first cable 31, a second cable 32) are connected at different positions on a peripheral side surface 111, and at least some of the cables are stored in a plurality of links (e.g., links 121 and 131) that are flexibly connected to the rotating disk 11, one end of which is fixed to the peripheral side surface 111 of the rotating disk 11 and the other end of which is located at a position independent of the rotation of the rotating disk 11 (e.g., surface 141 of the first engaging portion 14, surface 15 of the first engaging portion 15, and surface 16 of the first engaging portion 16). 51) and arranged in positions so as not to overlap in the direction of the rotation axis of the turntable 11 (for example, cable guide device 12 and cable guide device 13 in FIG. 1, cable guide device 22 and cable guide device 24, and cable guide device 23 and cable guide device 25 in FIG. 4), and the multiple cable guide devices are wound or unwound on or from the circumferential side surface 111 of the turntable 11 in accordance with the rotation of the turntable 11 in the circumferential direction.

[0039] As a result, multiple cable guide devices arranged on the circumferential side surface 111 of the rotating disk 11 at positions that do not overlap in the rotation axis direction are wound or unwound on the circumferential side surface 111 of the rotating disk 11 in accordance with the circumferential rotation of the rotating disk 11. As a result, the number of cables to be laid can be increased without stretching the rotating disk 11 in the rotation axis direction (i.e., without increasing the thickness of the rotating disk 11).

[0040] Here, the multiple cable guide devices may be arranged at positions where they do not interfere with each other when wound around the peripheral side surface 111 and when unwound. As a result, the multiple cable guide devices are arranged in positions where they do not interfere with each other, allowing the rotating disk 11 to rotate smoothly.

[0041] In addition, the multiple cable guide devices may be configured such that when one end is positioned in the 2 to 4 o'clock direction relative to the radial center of the turntable 11, the other end is not fixed in the 8 to 10 o'clock direction relative to the radial center of the turntable 11, and when one end is positioned in the 8 to 10 o'clock direction relative to the radial center of the turntable 11, the other end is not fixed in the 2 to 4 o'clock direction relative to the radial center of the turntable 11. This prevents the straight line connecting both ends of each of the multiple cable guide devices from being horizontal or nearly horizontal, thereby suppressing the amount of slack in the cable guide device toward the ground in the vertical direction due to its own weight. As a result, the risk that the cable guide device that has slackened toward the ground due to its own weight will interfere with other members and be damaged when the turntable 11 rotates is reduced.

[0042] In addition, as multiple cable guiding devices, a first cable guiding device (e.g., cable guiding device 12) and a second cable guiding device (e.g., cable guiding device 13) may be arranged, and one end of the first cable guiding device and one end of the second cable guiding device may be arranged in symmetrical positions with respect to the center of rotation of the turntable 11. As a result, one end of each of the first cable guide device and the second cable guide device wound around the circumferential side surface 111 of the rotating disk 11 is disposed at a symmetrical position with respect to the center of rotation of the rotating disk 11. As a result, one end of each of the first cable guide device and the second cable guide device is disposed exactly or approximately exactly opposite to each other, so that deviation of the center of gravity is unlikely to occur when the rotating disk 11 rotates, and smooth rotation can be realized. In addition, for example, by disposing a connection port of a pipe (for example, a temperature control pipe, etc.) through which a fluid flows near one end of each of the first cable guide device and the second cable guide device, the first cable guide device and the second cable guide device can guide the pipe while protecting most of the pipe. In this case, since two connection ports can be disposed exactly or approximately opposite to the rotating disk 11, a well-balanced arrangement can be realized with respect to the rotating disk 11 even when one connection port is an input port and the other connection port is an output port, or when an input port and an output port are disposed at both connection ports.

[0043] The rotating disk 11 may further include locking portions (e.g., first locking portions 14 and 15, second locking portions 16 and 17) that are arranged at positions independent of the rotation of the rotating disk 11 and lock each of the multiple cable guide devices that slacken toward the radially outward direction of the rotating disk 11. This engages multiple cable guide devices that slacken radially outward of the rotating disk 11 and controls their trajectory, preventing the slack portions of the cable guide devices from interfering with other components of the rotating device 1.

[0044] Also, the other end of each of the plurality of cable guide devices may be fixed to the engaging portion. As a result, the locking portion serves two purposes, that is, to lock the slack of each of the multiple cable guide devices and to fix the other end of each of the multiple cable guide devices, so there is no need to prepare a separate member for fixing the other end of each of the multiple cable guide devices, and as a result, the number of parts of the rotating device 1 can be reduced.

[0045] <Second embodiment> (Configuration of Rotating Device) 5 and 6 are diagrams showing an example of the external configuration of the rotating device 2 according to the second embodiment of the present invention. Fig. 5 shows the cable guide devices 42 and 43 in a state where they are fully wound around the rotating disk 41, and Fig. 6 shows the cable guide devices 42 and 43 in a state where they are fully unwound. The cable guide device 42 has a shorter length in the link connection direction than the cable guide device 12 of the rotating device 1 of Figs. 1 and 2 according to the above-mentioned first embodiment. In contrast, the cable guide device 43 has a longer length in the link connection direction than the cable guide device 13 of the rotating device 1 of Figs. 1 and 2.

[0046] The rotating device 2 shown in Figures 5 and 6 is configured to include a rotating disk 41, a cable guide device 42 as a first cable guide device, a cable guide device 43 as a second cable guide device, first locking portions 44 and 45, and second locking portions 46 and 47. In the rotating device 2 shown in Figures 5 and 6, the rotating disk 41, the first locking portions 44 and 45, and the second locking portions 46 and 47 are configured similarly to the rotating disk 11, the first locking portions 14 and 15, and the second locking portions 16 and 17 shown in Figures 1 and 2 described above, and therefore description thereof will be omitted.

[0047] The cable guide device 42 is a member that guides the first cable 61 by storing at least a portion of the first cable 61 in a plurality of connected links 421, and is configured, for example, by a so-called cable bear that enables the protection and guidance of a movable cable. One end of the cable guide device 42 is fixed to the peripheral side surface 411 of the turntable 41, and the other end is fixed to a surface 441 near the left end in the left-right direction of the first locking portion 44. The cable guide device 42 has a fixing portion 422 for fixing one end to the peripheral side surface 411 of the turntable 41, and a fixing portion 423 for fixing the other end to the surface 441 of the first locking portion 44.

[0048] The cable guide device 42 is bent in accordance with the rotation of the rotating disk 41 in the circumferential direction, and is wound or unwound on the circumferential side surface 411 of the rotating disk 41. As described above, FIG. 5 shows a state in which the cable guide device 42 is wound most around the circumferential side surface 411 of the rotating disk 41. Therefore, when the rotating disk 41 rotates to the right in the circumferential direction (rotates clockwise) from the state shown in FIG. 5, the cable guide device 42 bends in accordance with the rotation and is unwound while moving away from the circumferential side surface 411, and finally reaches the state shown in FIG. 6. Also, when the rotating disk 41 is reversed to the left in the circumferential direction (rotates counterclockwise) from the state shown in FIG. 6, the cable guide device 42 finally reaches the state shown in FIG. 5.

[0049] The cable guide device 43 is a member that guides the second cable 62 by storing at least a part of the second cable 62 in a plurality of connected links 431, and is configured, for example, by a so-called cable bear that enables protection and guidance of a movable cable. One end of the cable guide device 43 is fixed to the peripheral side surface 411 of the turntable 41, and the other end is fixed to a surface 451 near the right end in the left-right direction of the first locking part 45. The cable guide device 43 has a fixing part 432 for fixing one end to the peripheral side surface 411 of the turntable 41, and a fixing part 433 for fixing the other end to the surface 451 of the first locking part 45.

[0050] The cable guide device 43 is bent in accordance with the rotation of the rotating disk 41 in the circumferential direction, and is wound or unwound on the circumferential side surface 411 of the rotating disk 41. As described above, FIG. 5 shows a state in which the cable guide device 43 is wound most around the circumferential side surface 411 of the rotating disk 41. Therefore, when the rotating disk 41 rotates to the right in the circumferential direction (rotates clockwise) from the state shown in FIG. 5, the cable guide device 43 bends in accordance with the rotation and is unwound while moving away from the circumferential side surface 411, finally reaching the state shown in FIG. 6. Also, when the rotating disk 41 is reversed to the left in the circumferential direction (rotates counterclockwise) from the state shown in FIG. 6, the cable guide device 43 finally reaches the state shown in FIG. 5.

[0051] Here, of the multiple cable guide devices (two in this embodiment) constituting the rotating device 2 according to the second embodiment, the one arranged on the ground side is longer in the link connection direction than the one arranged on the top side in the vertical direction of the rotating disk 41. That is, in the example shown in Figures 5 and 6, cable guide device 43 arranged on the ground side is longer in the link connection direction than cable guide device 42 arranged on the top side in the vertical direction of the rotating disk 41.

[0052] When the cable guide devices 42 and 43 are inverted, they tend to slacken toward the ground due to their own weight. If the cable guide devices 42 and 43 slacken too much toward the ground, they may interfere with other components. For this reason, the cable guide devices 42 and 43 are designed so that the length in the link connection direction is long enough that they will not interfere with other components even if they slacken toward the ground due to their own weight.

[0053] However, since the cable guide device 43 is disposed on the ground side of the turntable 41, even if it slackens on the ground side due to its own weight, it is locked by the first locking portion 45. Therefore, the risk that the cable guide device 43 will interfere with other members is lower than the risk that the cable guide device 42, which is disposed on the top side of the turntable 41, will interfere with other members. For this reason, the length of the cable guide device 43 in the connection direction is less restricted than the length of the cable guide device 42 in the connection direction. As a result, the cable guide device 43 can be made longer in the connection direction than the cable guide device 42, as shown in Figs. 5 and 6.

[0054] In summary, the rotation device 2 according to the second embodiment of the present invention only needs to have the following configuration, and can take on a variety of different embodiments. That is, the rotating device 2 of the second embodiment is characterized in that it comprises a rotating plate 41 to which multiple cables (e.g., a first cable 61 and a second cable 62) are connected at different positions on a peripheral surface 411 and which can rotate in a circumferential direction, and multiple cable guide devices (e.g., cable guide devices 42 and 43) which store at least a portion of the cables in multiple links (e.g., link 421) which are flexibly connected, have one end fixed to the peripheral surface 411 of the rotating plate 41 and the other end fixed to a position independent of the rotation of the rotating plate 41 (e.g., surface 441 of the first engagement portion 44), and are arranged at positions which do not overlap in the direction of the rotation axis of the rotating plate 41, and in that the multiple cable guide devices are wound or unwound around the peripheral surface 411 of the rotating plate 41 in accordance with the circumferential rotation of the rotating plate 41.

[0055] Here, the multiple cable guiding devices may be configured so that the position where the other end is fixed (e.g., surface 441 of first engagement portion 44, surface 451 of first engagement portion 45) is longer in the link connection direction for the one arranged on the ground side (cable guiding device 43) than for the one arranged on the top side of the turntable 41 (cable guiding device 42). As a result, cable guide device 43, which is disposed on the ground side of turntable 41, is longer in the link connection direction than cable guide device 42, which is disposed on the top side in the top-to-bottom direction. Since cable guide device 43 is entirely locked by first locking portion 45 when inverted, it is less affected by interference with other members than cable guide device 42, which is prone to slackening toward the ground side in the top-to-bottom direction due to its own weight when inverted. Therefore, cable guide device 43 has fewer restrictions on the length in the connection direction than cable guide device 42, so the length in the link connection direction of cable guide device 43 can be made longer than the length in the link connection direction of cable guide device 42.

[0056] <Comparison of implementation forms> As described above, in the rotating device 1 according to the first embodiment, the lengths in the link connection direction of the multiple cable guide devices (cable guide devices 12 and 13) wound around the peripheral side surface 111 of the rotating plate 11 are the same. In contrast, in the rotating device 2 according to the second embodiment, the lengths in the link connection direction of the multiple cable guide devices (cable guide devices 42 and 43) wound around the peripheral side surface 411 of the rotating plate 41 are different. Specifically, as described above, the cable guide device 43 arranged on the ground side of the rotating plate 41 is longer in the link connection direction than the cable guide device 42 arranged on the top side in the top-to-bottom direction. For this reason, when comparing the rotating device 1 according to the first embodiment and the rotating device 2 according to the second embodiment, for example, the following can be said.

[0057] That is, in the rotating device 2 according to the second embodiment, the length in the connecting direction of the link 421 of the cable guide device 42 arranged on the top side of the rotating plate 41 is shorter than the length in the connecting direction of the link 431 of the cable guide device 43 arranged on the bottom side. Therefore, there is a low risk of interference that may occur when the cable guide device 42 slackens to the bottom side due to its own weight during reversal. In contrast, in the rotating device 1 according to the first embodiment, the lengths in the connecting direction of the links of the cable guide devices 12 and 13 are the same, so that deviation of the center of gravity is unlikely to occur when the rotating plate 11 rotates, and smooth rotation can be achieved.

[0058] <Other> In the above-described embodiments (first embodiment and second embodiment), the number of cable guide devices wound around the circumferential side surface of the rotating disk is two, but the present invention is not limited to this. The number of cable guide devices wound around the circumferential side surface of the rotating disk may be three or more. [Explanation of symbols]
