AI Technical Summary
Existing elevating control units for batons are limited by their height dimension, necessitating a reduction in size to accommodate more units on a control panel without increasing the panel's dimensions.
The elevating control unit for batons incorporates a plate member with a current cutoff unit on the front surface and a current direction switching unit on the rear, allowing the plate member to rotate, thus reducing the overall height and enabling efficient placement of components without increasing the panel's size.
This configuration allows for a more compact elevating control unit, enabling a higher density of units on the control panel, facilitating easier access and maintenance, and reducing interference between components.

DETAILED DESCRIPTION OF THE INVENTION
[0010] The lifting control unit (5) of the baton (1) according to the embodiment includes a plate member (36), a current cutoff unit (71), and a current direction switching unit (72). The plate member (36) includes a front surface (57) and a rear surface (58) facing the side opposite to the front surface (57). The current cutoff unit (71) is attached to the front surface (57) of the plate member (36) and can cut off the current. The current direction switching unit (72) is disposed on the rear side with respect to the plate member (36) and the current cutoff unit (71), and can switch the direction in which the current flowing to the lifting drive unit (3) of the baton (1) flows. Thereby, it becomes possible to reduce the size of the lifting control unit (5) along the height direction.
[0011] The lifting control unit (5) of the embodiment further includes a unit frame (35), and a plate member (36) is rotatably attached to the unit frame (35). The plate member (36) performs an opening / closing operation with respect to the unit frame (35) by rotating about the attachment position to the unit frame (35) as the rotation center. The current interruption part (71) rotates with respect to the unit frame (35) together with the plate member (36) in response to the opening / closing operation of the plate member (36). Due to such a configuration, by opening the plate member (36) with respect to the unit frame (35), it becomes possible to confirm the operating status of the current direction switching part (72) disposed on the rear side with respect to the plate member (36). Further, by opening the plate member (36) with respect to the unit frame (35), it becomes possible to access the current direction switching part (72) without removing the current direction switching part (72) from the unit frame (35).
[0012] In the lifting control unit (5) of the embodiment, the unit frame (35) includes a first side frame part (41) to which the plate member (36) is rotatably attached, and a second side frame part (42) disposed apart from the first side frame part (41) in the width direction intersecting both the height direction and the front-rear direction. The current direction switching part (72) is disposed in the width direction between the first side frame part (41) and the second side frame part (42) of the unit frame (35). The current direction switching part (72) is disposed at a position closer to the first side frame part (41) than the second side frame part (42). By adopting such a configuration, even when the plate member (36) is opened with respect to the unit frame (35), the separation distance between the current interruption part (71) and the current direction switching part (72) does not increase. As a result, it becomes unnecessary to lengthen a large number of wirings electrically connecting between the current interruption part (71) and the current direction switching part (72), and in a state where the plate member (36) is closed with respect to the unit frame (35) or the like, it is effectively prevented that a large number of wirings between the current interruption part (71) and the current direction switching part (72) are bent or the like.
[0013] The lifting control unit (5) of the embodiment further includes a unit frame (35), an attachment plate (73), and a circuit board (81). A plate member (36) is attached to the unit frame (35). The attachment plate (73) is detachably attached to the unit frame (35), and the circuit board (81) is mounted on the attachment plate (73). When the attachment plate (73) is attached to the unit frame (35), the circuit board (81) is attached to the unit frame (35) with the attachment plate (73) interposed therebetween. With such a configuration, after the attachment plate (73) is removed from the unit frame (35), the circuit board (81) can be replaced while the attachment plate (73) is moved to the front side of the lifting control unit (5) from the position where it was attached to the unit frame (35). This makes it easier to perform the replacement work of the circuit board (81).
[0014] The lifting control unit (5) of the embodiment further includes a unit frame (35). A plate member (36) is attached to the unit frame (35). The plate member (36) has a recess (65) that is recessed toward the side where the rear surface (58) faces with respect to the attachment position to the unit frame (35). The current cutoff portion (71) is attached to the plate member (36) in the recess (65). With such a configuration, the protruding amount of the current cutoff portion (71) toward the side where the front surface (57) of the plate member (36) faces is reduced. Thereby, in the lifting control panel (10), interference of the current cutoff portion (71) with units and the like arranged around the lifting control unit (5) is effectively prevented.
[0015] The lifting control unit (5) of the embodiment further includes a wiring board (82) and a plurality of types of relays (93). The wiring board (82) includes a board upper surface (91) facing upward in the height direction, and is disposed below the plate member (36), the current cutoff portion (71), and the current direction switching portion (72) in the height direction. The plurality of types of relays (93) are disposed on the board upper surface (91) of the wiring board (82), and the protruding height from the board upper surface (91) is different for each type. Among the plurality of types of relays (93), the highest protruding relay (93A), which is the type with the highest protruding height, is disposed on the foremost side. With such a configuration, it becomes possible to realize a configuration in which on the board upper surface (91) of the wiring board (82), electronic components with a high protruding height such as the highest protruding relay (93A) are not disposed in the rear region.
[0016] In the lifting control unit (5) of the embodiment, among the plurality of types of relays (93), the relays (93) with a higher protruding height are disposed more forward. Thereby, a configuration in which electronic components with a high protruding height are not disposed in the rear region on the board upper surface (91) of the wiring board (82) is more appropriately realized.
[0017] The lifting control unit (5) of the embodiment further includes a front connector (95). The front connector (95) is disposed forward of any of the plurality of types of relays (93) on the board upper surface (91) of the wiring board (82). Wires are inserted into the front connector (95) from the front side. With such a configuration, at the usage site of the lifting control unit (5), a constructor or the like can connect wires to the front connector (95) without removing the circuit board (81) from the unit frame (35). Also, when it becomes necessary to cut off the power supply to the lifting control unit (5), it is possible to easily and instantaneously remove the wires from the front connector (95).
[0018] The lifting control panel (10) of the baton (1) in the embodiment includes the aforementioned lifting control unit (5) and the panel frame (12). The lifting control unit (5) is attached to the panel frame (12). By configuring the lifting control unit (5) as described above, it becomes possible to mount the lifting control unit (5) with a small dimension in the height direction on the lifting control panel (10). As a result, without increasing the size of the lifting control panel (10), it is possible to increase the number of lifting control units (5) mounted on the lifting control panel (10).
[0019] Hereinafter, the embodiment will be described with reference to the drawings.
[0020] FIG. 1 schematically shows an example of the usage mode of the baton 1 in the embodiment. The baton 1 is used in a studio, a stage, etc., and is used with lighting equipment, audio equipment, etc. (none of which are shown) suspended from the baton 1. The baton 1 with lighting equipment etc. suspended is movable (liftable) along the vertical direction. Therefore, the lifting direction of the baton 1 coincides with or substantially coincides with the vertical direction.
[0021] At the place where the baton 1 is used, etc., the baton 1 is suspended from the ceiling 8 by the wire 2. In an example such as FIG. 1, the baton 1 is suspended via two wires 2. Also, the two wires 2 are connected to the baton 1 at positions separated from each other in the horizontal direction. At the place where the baton 1 is used, etc., for each baton 1, one lifting drive unit 3 and one lifting control unit 5 are provided. The lifting drive unit 3 is installed on the ceiling 8, for example, and includes a winding machine 6 such as a winch.
[0022] Each of the wires 2 connected to the baton 1 extends from the winding machine 6. At the place where the baton 1 is used, etc., for one baton 1, the same number of pulleys 7 as the number of the connected wires 2 are provided. In an example of FIG. 1, for one baton 1, two pulleys 7 are provided. Each of the wires 2 extending from the winding machine 6 is hung on one corresponding pulley 7 and extends vertically downward from the one corresponding pulley 7 to the connection position to the baton 1.
[0023] In the lifting drive unit 3, as the take-up machine 6 rotates in one direction around the axis of the rotating shaft, the wires 2 are each fed out from the take-up machine 6. Then, corresponding to the feeding operation of the wire 2, the baton 1 to which the wire 2 is connected descends vertically downward. On the other hand, as the take-up machine 6 rotates in the direction opposite to the rotation in the feeding operation around the axis of the rotating shaft, the wires 2 are each wound around the take-up machine 6. Then, corresponding to the winding operation of the wire 2, the baton 1 to which the wire 2 is connected ascends vertically upward. In each of the descending and ascending operations of the baton 1, the greater the rotational speed of the take-up machine 6, the greater the moving speed of the baton 1.
[0024] The lifting control unit 5 controls the drive of the lifting drive unit 3 by controlling the supply state of the current to the lifting drive unit 3. By controlling the drive of the lifting drive unit 3, operations such as the winding operation and the feeding operation of the wire 2 by the take-up machine 6 are controlled, and the lifting operation of the baton 1 is controlled. When the lifting drive unit 3 is driven by the supply of current, the take-up machine 6 rotates, and the feeding operation or the winding operation of the wire 2 is performed. Therefore, when current is supplied to the lifting drive unit 3, the baton 1 performs a lifting operation. At this time, in one example, the greater the magnitude of the current supplied to the lifting drive unit 3, the greater the rotational speed of the take-up machine 6, and the greater the moving speed of the baton 1 in each of the ascending and descending operations of the baton 1.
[0025] Further, when the direction in which the current flows supplied to the lifting drive unit 3 is switched, in the lifting drive unit 3, the rotational direction of the take-up machine 6 is switched, and the state between the descending operation and the ascending operation of the baton 1 is switched. For this reason, in the state where the winding operation of the wire 2 is being performed, the direction in which the current flows supplied to the lifting drive unit 3 is opposite to the state where the feeding operation of the wire 2 is being performed. Therefore, in the state where the ascending operation of the baton 1 is being performed, the direction in which the current flows supplied to the lifting drive unit 3 is opposite to the state where the descending operation of the baton 1 is being performed.
[0026] In studios, stages, etc., a plurality of the batons 1 as described above are used. Also, as described above, the lifting control unit 5 is provided one by one for each baton 1. And in places where a plurality of batons 1 are used, a plurality of the lifting control units 5 are implemented in one lifting control panel, and the lifting operations of each of the plurality of batons 1 are controlled.
[0027] FIG. 2 shows, in a perspective view, an example of the configuration of the lifting control panel 10 according to the embodiment. In the example of FIG. 2, the lifting control panel 10 is composed of a single lifting control module 11. As shown in FIG. 2, in the lifting control module 11, a front-rear direction (the directions indicated by arrow X1 and arrow X2), a width direction (the directions indicated by arrow Y1 and arrow Y2) that intersects (is orthogonal or substantially orthogonal) to the front-rear direction, and a height direction (the directions indicated by arrow Z1 and arrow Z2) that intersects (is orthogonal or substantially orthogonal) to both the front-rear direction and the width direction are defined. Also, in the lifting control module 11, one side in the front-rear direction becomes the front side (arrow X1 side), and the side opposite to the front side in the front-rear direction becomes the rear side (arrow X2 side). And in the lifting control module 11, one side in the height direction becomes the upper side (arrow Z1 side), and the side opposite to the upper side in the height direction becomes the lower side (arrow Z2 side).
[0028] As shown in FIG. 2, the lifting control module 11 of the lifting control panel 10 includes a plurality of the lifting control units 5 and also includes a panel frame 12 to which the plurality of the lifting control units 5 are attached. The panel frame 12 is formed of, for example, metal. In the lifting control module 11 of the example of FIG. 2, 24 lifting control units 5 are attached to the panel frame 12. Therefore, it becomes possible to control the lifting operations of 24 batons 1 by the 24 lifting control units 5 implemented in one lifting control module 11.
[0029] In addition, in the lifting control module 11, a plurality of unit columns 13 in which the plurality of lifting control units 5 are arranged along the width direction are formed in a plurality of rows. And in the lifting control module 11, the plurality of unit columns 13 in the plurality of rows are arranged along the height direction. In an example of FIG. 2, six unit columns 13 are arranged along the height direction of the lifting control module 11, and in each of the six unit columns 13, four lifting control units 5 are arranged along the width direction of the lifting control module 11. Note that the six unit columns 13 are also denoted as unit columns 13A, 13B, 13C, 13D, 13E, and 13F in order from the upper side in the height direction.
[0030] FIG. 3 shows a perspective view of the configuration of the board frame 12 of the lifting control module 11 in an example of FIG. 2. As shown in FIG. 2, FIG. 3, etc., a storage cavity 15 is formed inside the board frame 12, and the plurality of lifting control units 5 attached to the board frame 12 are arranged in the storage cavity 15. The board frame 12 includes a front frame portion 21, a rear frame portion 22, an upper frame portion 23, a lower frame portion 25, and a pair of side frame portions 26 and 27. The front frame portion 21 forms the front end of the lifting control module 11 and is adjacent to the storage cavity 15 from the front side. The rear frame portion 22 forms the rear end of the lifting control module 11 and is adjacent to the storage cavity 15 from the rear side. Also, the rear frame portion 22 faces the front frame portion 21 with the storage cavity 15 interposed therebetween in the front-rear direction of the lifting control module 11.
[0031] The upper frame portion 23 forms the upper end of the lifting control module 11 and is adjacent to the storage cavity 15 from the upper side in the height direction. The lower frame portion 25 forms the lower end of the lifting control module 11 and is adjacent to the storage cavity 15 from the lower side in the height direction. Further, the lower frame portion 25 faces the upper frame portion 23 with the storage cavity 15 interposed therebetween in the height direction of the lifting control module 11. The side frame portion 26 forms one end of the lifting control module 11 in the width direction and is adjacent to the storage cavity 15 from one side in the width direction. The side frame portion 26 forms the end of the lifting control module 11 on the side opposite to the side frame portion 26 in the width direction and is adjacent to the storage cavity 15 from the side opposite to the side frame portion 26 in the width direction. Further, the side frame portion 27 faces the side frame portion 26 with the storage cavity 15 interposed therebetween in the width direction of the lifting control module 11.
[0032] The side frame portion 26 includes a columnar portion 31, and the side frame portion 27 includes a columnar portion 32. In the side frame portion 26, the columnar portion 31 extends along the height direction from the upper end to the lower end, and in the side frame portion 27, the columnar portion 32 extends along the height direction from the upper end to the lower end. Each of the columnar portions 31 and 32 is arranged between the front frame portion 21 and the rear frame portion 22 in the front-rear direction and is arranged at the central portion of the lifting control module 11 in the front-rear direction.
[0033] Further, the board frame 12 includes a plurality of bridging board portions 33, and each of the plurality of bridging board portions 33 is bridged between the columnar portions 31 and 32. Each of the bridging board portions 33 extends along the width direction of the lifting control module 11 from the columnar portion 31 to the columnar portion 32. Also, the plurality of bridging board portions 33 are arranged between the front frame portion 21 and the rear frame portion 22 in the front-rear direction and are arranged at the central portion of the lifting control module 11 in the front-rear direction. And the plurality of bridging board portions 33 are arranged with intervals from each other in the height direction. In an example of FIGS. 2 and 3, seven bridging board portions 33 are bridged between the columnar portions 31 and 32. Note that the seven bridging board portions 33 are also denoted as bridging board portions 33A, 33B, 33C, 33D, 33E, 33F, and 33G in order from the upper side in the height direction.
[0034] In an example of FIG. 2, each of the lifting control units 5 constituting the unit row 13A is disposed between the bridging plate portions 33A and 33B in the height direction and is connected to the bridging plate portions 33A and 33B. Each of the lifting control units 5 constituting the unit row 13B is disposed between the bridging plate portions 33B and 33C in the height direction and is connected to the bridging plate portions 33B and 33C. Each of the lifting control units 5 constituting the unit row 13C is disposed between the bridging plate portions 33C and 33D in the height direction and is connected to the bridging plate portions 33C and 33D. Each of the lifting control units 5 constituting the unit row 13D is disposed between the bridging plate portions 33D and 33E in the height direction and is connected to the bridging plate portions 33D and 33E. Each of the lifting control units 5 constituting the unit row 13E is disposed between the bridging plate portions 33E and 33F in the height direction and is connected to the bridging plate portions 33E and 33F. Each of the lifting control units 5 constituting the unit row 13F is disposed between the bridging plate portions 33F and 33G in the height direction and is connected to the bridging plate portions 33F and 33G.
[0035] As described above, each of the lifting control units 5 is disposed between two adjacent bridging plate portions 33 in the height direction. And each of the lifting control units 5 is attached to the board frame 12 in a state of being connected to each of the bridging plate portion 33 adjacent above in the height direction and the bridging plate portion 33 adjacent below in the height direction. Further, in an example of FIGS. 2 and 3, in the accommodation cavity 15 of the lifting control module 11, a unit (not shown) other than the lifting control unit 5 such as a terminal block is disposed between the bridging plate portion 33G and the lower frame portion 25 in the height direction.
[0036] In an example of FIGS. 2 and 3, the lift control panel 10 is composed of a single lift control module 11, but it is not limited thereto. In one example, one lift control panel 10 is composed of two lift control modules 11. In this case, if the two lift control modules 11 are the lift control modules 11A and 11B, in the lift control panel 10, the upper side in the height direction of the lift control module 11A coincides with or substantially coincides with the upper side in the height direction of the lift control module 11B, and the width direction of the lift control module 11A coincides with or substantially coincides with the width direction of the lift control module 11B, and the lift control modules 11A and 11B are arranged. Also, in the lift control panel 10, the two lift control modules 11A and 11B are arranged without shifting or hardly shifting relative to each other in both the height direction and the width direction.
[0037] Further, in the lift control panel 10 composed of two lift control modules 11, the lift control module 11B is connected from the rear side of the lift control module 11A. And, in the lift control panel 10, the two lift control modules 11A and 11B are arranged in a state where the front side of the lift control module 11B is on the opposite side to the front side of the lift control module 11A. For example, it is assumed that 24 lift control units 5 are mounted on each of the two lift control modules 11 constituting the lift control panel 10. In this case, 48 lift control units 5 are mounted on one lift control panel 10, and it is possible to control the lifting operations of 48 battens 1 by the 48 lift control units 5 mounted on the lift control panel 10.
[0038] Hereinafter, a configuration and the like of any one of the lift control units 5 mounted on the lift control panel 10 will be described. Note that the configurations and the like of the other lift control units 5 mounted on the lift control panel 10 are the same as the configurations and the like described below.
[0039] Figs. 4 and 5 show the configuration of the lifting control unit 5 according to the embodiment in a perspective view. As shown in Figs. 4 and 5, in the lifting control unit 5, a front-rear direction (the directions indicated by arrows X3 and X4), a width direction (the directions indicated by arrows Y3 and Y4) that intersects (is orthogonal or substantially orthogonal) to the front-rear direction, and a height direction (the directions indicated by arrows Z3 and Z4) that intersects (is orthogonal or substantially orthogonal) to both the front-rear direction and the width direction are defined. Also, in the lifting control unit 5, one side in the front-rear direction is the front side (arrow X3 side), and the side opposite to the front side in the front-rear direction is the rear side (arrow X4 side). And in the lifting control unit 5, one side in the height direction is the upper side (arrow Z3 side), and the side opposite to the upper side in the height direction is the lower side (arrow Z4 side).
[0040] In the lifting control panel 10, in a state where the upper side in the height direction of the lifting control unit 5 coincides or substantially coincides with the upper side in the height direction of the lifting control module 11, and the width direction of the lifting control unit 5 coincides or substantially coincides with the width direction of the lifting control module 11, the lifting control unit 5 is attached to the panel frame 12. And in a state where the lifting control unit 5 is attached to the panel frame 12, the front side of the lifting control unit 5 coincides or substantially coincides with the front side of the lifting control module 11, and the rear side of the lifting control unit 5 coincides or substantially coincides with the rear side of the lifting control module 11.
[0041] The lifting control unit 5 includes a unit frame 35 and a plate member 36. The unit frame 35 and the plate member 36 are formed of, for example, metal. Fig. 6 shows the configuration of the unit frame 35 and the plate member 36 in the lifting control unit 5 in a perspective view. As shown in Figs. 4 to 6 and the like, the unit frame 35 includes a pair of side frame portions 41, 42, a bottom plate portion 43, and a rear plate portion 45. In the unit frame 35, the pair of side frame portions 41, 42 are arranged apart from each other in the width direction of the lifting control unit 5. In the unit frame 35, the side frame portion (the first side frame portion) 41 is arranged at one end in the width direction, and the side frame portion (the second side frame portion) 42 is arranged at the end opposite to the side frame portion 41 in the width direction.
[0042] The bottom plate portion 43 is connected to the lower ends of the respective side frame portions 41 and 42, and extends along the width direction of the lifting control unit 5 from the lower end of the side frame portion 41 to the lower end of the side frame portion 42. The rear plate portion 45 is connected to the rear ends of the respective side frame portions 41 and 42, and extends along the width direction of the lifting control unit 5 from the rear end of the side frame portion 41 to the rear end of the side frame portion 42. The rear plate portion 45 is arranged away from the bottom plate portion 43 upward in the height direction.
[0043] In the unit frame 35 of an example shown in FIGS. 4 to 6, an extension plate portion (first extension plate portion) 46 is formed at the front end of the side frame portion (first side frame portion) 41, and an extension plate portion (second extension plate portion) 47 is formed at the front end of the side frame portion (second side frame portion) 42. In the side frame portion 41, the extension plate portion 46 protrudes inward in the width direction with respect to the other portion of the side frame portion 41. Also, in the side frame portion 42, the extension plate portion 47 protrudes inward in the width direction with respect to the other portion of the side frame portion 42. Each of the extension plate portion 46 of the side frame portion 41 and the extension plate portion 47 of the side frame portion 42 is arranged away from the rear plate portion 45 forward and away from the bottom plate portion 43 upward in the height direction. And the extension plate portions 46 and 47 are arranged away from each other in the width direction of the lifting control unit 5.
[0044] Also, in the unit frame 35 of an example shown in FIGS. 4 to 6, a protruding plate portion 48 is connected to the front end of the bottom plate portion 43. The protruding plate portion 48 protrudes downward in the height direction with respect to the bottom plate portion 43 and the side frame portions 41 and 42. A hole 51 penetrating the extension plate portion 46 in the front-rear direction of the lifting control unit 5 is formed at the upper end portion of the extension plate portion 46, and a hole 52 penetrating the extension plate portion 47 in the front-rear direction of the lifting control unit 5 is formed at the upper end portion of the extension plate portion 47. Also, two holes 55 and 56 are formed in the protruding plate portion 48, and each of the holes 55 and 56 penetrates the protruding plate portion 48 in the front-rear direction of the lifting control unit 5. Also, the holes 55 and 56 are arranged away from each other in the width direction of the lifting control unit 5.
[0045] In the lifting control module 11 of the lifting control panel 10, each of the lifting control units 5 is connected to the bridging plate portion 33 adjacent to the upper side in the height direction through each of the holes 51 and 52. And in the lifting control module 11, each of the lifting control units 5 is connected to the bridging plate portion 33 adjacent to the lower side in the height direction through each of the holes 55 and 56. For example, for each of the lifting control units 5 constituting the unit row 13A, each of the holes 51 and 52 connects the lifting control unit 5 to the bridging plate portion 33A, and each of the holes 55 and 56 connects the lifting control unit 5 to the bridging plate portion 33B.
[0046] In the lifting control unit 5, the plate member 36 is rotatably attached to the unit frame 35. Therefore, the plate member 36 is rotatable with respect to the unit frame 35 about the attachment position to the unit frame 35 as the rotation center. In an example of FIGS. 4 to 6, the plate member 36 is attached to the front end portion of the side frame portion (first side frame portion) 41 in the unit frame 35. And the plate member 36 is attached to the side frame portion 41 via the hinge 53 and is rotatable with respect to the unit frame 35 about the rotation axis P along the height direction of the lifting control unit 5 as the rotation center.
[0047] The plate member 36 performs an opening and closing operation with respect to the unit frame 35 by rotating about the attachment position to the unit frame 35 as the rotation center. In FIGS. 4 and 6, the state where the plate member 36 is closed with respect to the unit frame 35 is shown, and in FIG. 5, the state where the plate member 36 is open with respect to the unit frame 35 is shown.
[0048] The plate member 36 includes a front surface 57 and a rear surface 58 facing the side opposite to the front surface 57. Here, in the plate member 36, the front-rear direction is defined. In the plate member 36, the side facing the front surface 57 is defined as the front side, which is one side of the front-rear direction. And in the plate member 36, the side facing the rear surface 58 is defined as the rear side, which is the side opposite to the front side in the front-rear direction. Also, in the plate member 36, a width direction that intersects (is orthogonal or substantially orthogonal) to the front-rear direction, and a height direction that intersects (is orthogonal or substantially orthogonal) to both the front-rear direction and the width direction are defined. In the lifting control unit 5, the plate member 36 is attached to the side frame portion 41 of the unit frame 35 in a state where the height direction of the plate member 36 coincides or substantially coincides with the height direction of the lifting control unit 5.
[0049] In an example of FIGS. 4 to 6, in a state where the plate member 36 is closed with respect to the unit frame 35, the width direction of the plate member 36 coincides or substantially coincides with the width direction of the lifting control unit 5. In a state where the plate member 36 is closed with respect to the unit frame 35, the front side of the plate member 36 coincides or substantially coincides with the front side of the lifting control unit 5, and the rear side of the plate member 36 coincides or substantially coincides with the rear side of the lifting control unit 5.
[0050] The plate member 36 includes a pair of end plate portions 61, 62, and each of the end plate portions 61, 62 is formed in a plate shape in which the front-rear direction of the plate member 36 becomes the plate thickness direction. In the plate member 36, one end (edge) of the width direction is formed by the end plate portion (the first end plate portion) 61, and the end (edge) on the side opposite to the end plate portion 61 in the width direction is formed by the end plate portion (the second end plate portion) 62. And in the plate member 36, the end plate portions 61, 62 are arranged away from each other in the width direction.
[0051] In the plate member 36, the end plate portion 61 is connected to the side frame portion 41 of the unit frame 35, and the attachment position to the unit frame 35 is formed by the end plate portion 61. And in the plate member 36, the rotation center of the rotation with respect to the unit frame 35 is formed by the end plate portion 61. For this reason, in the unit frame 35, the end portion on the side where the side frame portion 41 is located in the width direction becomes the end portion on the side to which the plate member 36 is connected, and also becomes the end portion on the side where the rotation center of the rotation of the plate member 36 is located. And in the unit frame 35, the end portion on the side where the side frame portion 42 is located in the width direction becomes the end portion on the side opposite to the side to which the plate member 36 is connected, and also becomes the end portion on the side opposite to the side where the rotation center of the rotation of the plate member 36 is located.
[0052] In an example of FIGS. 4 to 6, when the plate member 36 is in a closed state with respect to the unit frame 35, the end plate portion 61 of the plate member 36 abuts on the extended plate portion 46 of the side frame portion 41 from the front side of the lifting control unit 5. And when the plate member 36 is in a closed state with respect to the unit frame 35, the end plate portion 62 of the plate member 36 abuts on the extended plate portion 47 of the side frame portion 42 from the front side of the lifting control unit 5. Also, in the plate member 36, a knob member 63 is attached to the lower end portion of the end plate portion 62. The knob member 63 can be operated by a user of the lifting control unit 5 and the lifting control panel 10 or the like. Also, when the plate member 36 is in a closed state with respect to the unit frame 35, the knob member 63 can be engaged with the extended plate portion 47 of the side frame portion 42.
[0053] When the plate member 36 is closed with respect to the unit frame 35 and the knob member 63 is not engaged with the extended plate portion 47, for example, a user of the lifting control unit 5 and the lifting control panel 10 or the like can operate the knob member 63 or the like to engage the knob member 63 with the extended plate portion 47 of the side frame portion 42. When the knob member 63 is engaged with the extended plate portion 47, the rotation of the plate member 36 with the attachment position to the unit frame 35 as the rotation center is restricted. Thereby, the plate member 36 becomes unable to perform an opening / closing operation with respect to the unit frame 35, and the state where the plate member 36 is closed with respect to the unit frame 35 is maintained.
[0054] Also, when the plate member 36 is closed with respect to the unit frame 35 and the knob member 63 is engaged with the extended plate portion 47, for example, users of the lifting control unit 5 and the lifting control panel 10 can operate the knob member 63 to disengage the knob member 63 from the extended plate portion 47 of the side frame portion 42. By disengaging the knob member 63 from the extended plate portion 47, the plate member 36 can rotate about the attachment position to the unit frame 35. As a result, the plate member 36 can open and close with respect to the unit frame 35.
[0055] Further, in the plate member 36, recesses 65 that are recessed toward the rear side of the plate member 36 are formed with respect to the end plate portions 61, 62. The recesses 65 are recessed toward the side where the rear surface 58 faces with respect to the end plate portions 61, 62. For this reason, in the plate member 36, the recesses 65 are recessed toward the side where the rear surface 58 faces with respect to the attachment position to the side frame portion 41 of the unit frame 35. The recesses 65 include recess bottoms 66, and the recess bottoms 66 form the bottoms of the recesses 65. Also, in the plate member 36, the recesses 65 are formed between the end plate portions 61, 62 in the width direction.
[0056] When the plate member 36 is closed with respect to the unit frame 35, the recesses 65 of the plate member 36 are disposed between the side frame portions 41, 42 and between the extended plate portions 46, 47 in the width direction of the lifting control unit 5. Also, when the plate member 36 is closed with respect to the unit frame 35, the recess bottoms 66 of the recesses 65 of the plate member 36 are disposed on the rear side of the lifting control unit 5 with respect to the extended plate portions 46, 47 and the protruding plate portion 48. In the lifting control unit 5, regardless of the open / closed state of the plate member 36 with respect to the unit frame 35, the plate member 36 including the recesses 65 is located on the front side with respect to the rear plate portion 45. For this reason, even when the plate member 36 is closed with respect to the unit frame 35, the recess bottoms 66 of the recesses 65 of the plate member 36 are disposed on the front side of the lifting control unit 5 with respect to the rear plate portion 45.
[0057] Further, in the unit frame 35, the rear plate portion 45 includes a front surface 67 and a rear surface 68 facing the side opposite to the front surface 67. In the rear plate portion 45, the front surface 67 faces the front side of the lifting control unit 5 and the side where the plate member 36 is located. When the plate member 36 is in a closed state with respect to the unit frame 35, the front surface 67 of the rear plate portion 45 faces the rear surface 58 of the unit frame 35. Also, in the rear plate portion 45, the rear surface 68 faces the rear side of the lifting control unit 5 and the side opposite to the side where the plate member 36 is located.
[0058] As shown in FIGS. 4 and 5 and the like, a current cutoff portion 71 and a current direction switching portion 72 are mounted on the lifting control unit 5. The current cutoff portion 71 can cut off the current supplied to the lifting drive portion 3 and the like. In one example, the current cutoff portion 71 is composed of a wiring current cutoff device such as an MCCB (molded case circuit breaker). In this case, the current cutoff portion 71 cuts off the current supplied through the wiring in response to the occurrence of an abnormal overcurrent in the lifting drive portion 3.
[0059] In another example, the current cutoff portion 71 is composed of a leakage cutoff device such as an ELB (earth leakage circuit breaker). In this case, the current cutoff portion 71 cuts off the current output from the power source and the like in response to the occurrence of leakage. When the current cutoff portion 71 is composed of a leakage cutoff device, the current cutoff portion 71 cuts off the current in response to the occurrence of leakage and also cuts off the current in response to the occurrence of an abnormal overcurrent in the lifting drive portion 3. Also, the current cutoff portion 71 can be operated by the user of the lifting control unit 5 and the lifting control panel 10 and the like. Therefore, the user of the lifting control unit 5 and the lifting control panel 10 and the like can cut off the current supplied from the power source to the lifting drive portion 3 by operating the current cutoff portion 71.
[0060] The current direction switching unit 72 can switch the direction in which the current flowing to the lifting drive unit 3 flows. The current direction switching unit 72 is composed of, for example, a reversible electromagnetic contactor such as a reversible MC (magnet contact). In the lifting control unit 5, when the operating state of the current direction switching unit 72 is switched, the direction of the current supplied to the lifting drive unit 3 is switched. Therefore, the current direction switching unit 72 enables the rotation direction of the take-up machine 6 of the lifting drive unit 3 to be switched, and enables switching between the take-up operation and the pay-out operation of the wire 2. Accordingly, the current direction switching unit 72 enables switching between the lowering operation and the raising operation of the baton 1.
[0061] In the present embodiment, the current cut-off unit 71 is attached to the front surface 57 of the plate member 36. Therefore, the current cut-off unit 71 rotates with the plate member 36 with respect to the unit frame 35 in correspondence with the opening and closing operation of the plate member 36. At this time, the current cut-off unit 71 rotates with the attachment position of the plate member 36 to the side frame portion 41 of the unit frame 35 as the rotation center, that is, with the rotation axis P as the rotation center. Further, in an example of FIGS. 4 and 5, the current cut-off unit 71 is attached to the plate member 36 in the recess 65 and is disposed at the bottom portion 66 of the recess 65.
[0062] Also, in the unit frame 35 of the lifting control unit 5, the current direction switching unit 72 is attached to the front surface 67 of the rear plate portion 45. And in the lifting control unit 5, regardless of the open / closed state of the plate member 36 with respect to the unit frame 35, the current direction switching unit 72 is disposed on the rear side with respect to the plate member 36 and the current cut-off unit 71. When the plate member 36 is closed with respect to the unit frame 35, a space is formed between the rear plate portion 45 of the unit frame 35 and the recess 65 of the plate member 36 in the front-rear direction of the lifting control unit 5. And when the plate member 36 is closed with respect to the unit frame 35, the current direction switching unit 72 is disposed in the space between the rear plate portion 45 and the recess 65.
[0063] The current direction switching unit 72 is disposed between the side frame parts 41 and 42 in the width direction of the lifting control unit 5. Also, in an example of FIGS. 4 and 5, in the unit frame 35, among the side frame parts (first side frame part) 41, the side frame part (first side frame part) 41 is disposed closer to the current direction switching unit 72 than the side frame part (second side frame part) 42. That is, the current direction switching unit 72 is disposed closer to the side frame part 41 than the side frame part 42. For this reason, the distance along the width direction of the lifting control unit 5 from the side frame part 41 to the current direction switching unit 72 is smaller than the distance along the width direction of the lifting control unit 5 from the side frame part 42 to the current direction switching unit 72. Therefore, in the unit frame 35, the end on the side to which the plate member 36 is connected is located closer to the current direction switching unit 72 than the end on the side opposite to the side to which the plate member 36 is connected. That is, in the unit frame 35, the end on the side where the rotation center of the plate member 36 is located is located closer to the current direction switching unit 72 than the end on the side opposite to the side where the rotation center of the plate member 36 is located.
[0064] Also, in the lifting control unit 5, the attachment plate 73 is detachably attached to the unit frame 35. In an example of FIGS. 4 and 5 and the like, in the lifting control unit 5, the attachment plate 73 is attached to the unit frame 35 in a state of being located below the plate member 36, the rear plate part 45, the current cutoff part 71, and the current direction switching unit 72 in the height direction. Also, in a state where the attachment plate 73 is attached to the unit frame 35, the attachment plate 73 is disposed apart downward in the height direction of the lifting control unit 5 with respect to the plate member 36, the rear plate part 45, the current cutoff part 71, and the current direction switching unit 72.
[0065] In an example such as FIGS. 4 and 5, the attachment plate 73 includes a substrate mounting portion 74 and a connection plate portion 75. The substrate mounting portion 74 is formed in a plate shape, and in the attachment plate 73, the connection plate portion 75 is connected to the edge of the substrate mounting portion 74. The attachment plate 73 is attached to the unit frame 35 in a state where the thickness direction of the substrate mounting portion 74 coincides with or substantially coincides with the height direction of the lifting control unit 5, and the thickness direction of the connection plate portion 75 coincides with or substantially coincides with the front-rear direction of the lifting control unit 5. Further, in a state where the attachment plate 73 is attached to the unit frame 35, the substrate mounting portion 74 is adjacent to the bottom plate portion 43 from above in the height direction of the lifting control unit 5, and the connection plate portion 75 is adjacent to the protruding plate portion 48 from the front side of the lifting control unit 5.
[0066] In the attachment plate 73, two holes 76 and 77 are formed in the connection plate portion 75, and each of the holes 76 and 77 penetrates the connection plate portion 75 in the thickness direction of the connection plate portion 75. The attachment plate 73 is attached to the unit frame 35 by being connected to the protruding plate portion 48 at each of the holes 76 and 77. Further, the attachment plate 73 is removed from the unit frame 35 when the connection to the protruding plate portion 48 at the holes 76 and 77 is released. In a state where the attachment plate 73 is removed from the unit frame 35, it becomes possible to move the attachment plate 73 relative to the unit frame 35. For example, by removing the attachment plate 73 from the unit frame 35, it becomes possible to move the attachment plate 73 from the position where it was attached to the unit frame 35 to the front side of the lifting control unit 5.
[0067] Further, a circuit board 81 is mounted on the substrate mounting portion 74 of the attachment plate 73. In the lifting control unit 5, since the attachment plate 73 is attached to the unit frame 35 as described above, the circuit board 81 is attached to the unit frame 35 with the attachment plate 73 interposed therebetween. In a state where the attachment plate 73 and the circuit board 81 are attached to the unit frame 35, the circuit board 81 is positioned above the attachment plate 73 and the bottom plate portion 43 in the height direction of the lifting control unit 5, and the substrate mounting portion 74 of the attachment plate 73 is positioned between the circuit board 81 and the bottom plate portion 43 in the height direction of the lifting control unit 5. Further, in a state where the attachment plate 73 and the circuit board 81 are attached to the unit frame 35, the circuit board 81 is positioned below the plate member 36, the rear plate portion 45, the current cutoff portion 71, and the current direction switching portion 72 in the height direction of the lifting control unit 5.
[0068] Also, in a state where the attachment plate 73 is removed from the unit frame 35, the circuit board 81 can move together with the attachment plate 73 relative to the unit frame 35. For example, by removing the attachment plate 73 from the unit frame 35, it becomes possible to move the attachment plate 73 and the circuit board 81 from the position where they were attached to the unit frame 35 to the front side of the lifting control unit 5. The circuit board 81 is, for example, a printed circuit board. On the circuit board 81, a plurality of electronic components 83 are mounted on a wiring board 82 such as a printed wiring board. A control circuit for controlling the operation of the baton 1 is formed on the circuit board 81. In one example, the control circuit formed on the circuit board 81 controls the operation of the current direction switching portion 72 and the supply of current to the lifting drive portion 3.
[0069] Also, in the lifting control unit 5 in one example of FIGS. 4 and 5, a shock relay 85 is mounted as an overload suppression portion for suppressing an overload in the lifting drive portion 3. In the unit frame 35, the shock relay 85 is attached to the front surface 67 of the rear plate portion 45. Therefore, in the lifting control unit 5, the shock relay 85 is disposed on the rear side with respect to the plate member 36 and the current cutoff portion 71.
[0070] Further, the shock relay 85 is arranged between the side frame portions 41 and 42 in the width direction of the lifting control unit 5. In an example of FIGS. 4 and 5, the shock relay 85 is arranged between the side frame portions 41 and 42 in the width direction of the lifting control unit 5 and is arranged between the current direction switching unit 72 and the side frame portion 42. For this reason, the current direction switching unit 72 is arranged on the side where the side frame portion (first side frame portion) 41 is located with respect to the shock relay 85 in the width direction of the lifting control unit 5. Therefore, the current direction switching unit 72 is arranged on the side where the end portion on the side to which the plate member 36 is connected is located with respect to the shock relay 85 in the width direction of the lifting control unit 5. That is, the current direction switching unit 72 is arranged at a position closer to the end portion on the side where the rotation center of the plate member 36 is located than the shock relay 85 in the width direction of the lifting control unit 5.
[0071] The shock relay 85 outputs a signal to the control circuit of the circuit board 81 in response to the magnitude of the current supplied to the lifting drive unit 3 becoming equal to or greater than the reference current value. In the lifting control unit 5, the control circuit of the circuit board 81 cuts off the current supplied to the lifting drive unit 3 in response to the signal being transmitted from the shock relay 85. Thereby, overcurrent in the lifting drive unit 3 is suppressed, and overload in the lifting drive unit 3 is suppressed.
[0072] Note that the shock relay 85 does not necessarily have to be implemented in the lifting control unit 5. In one example, a thermal relay is implemented in the lifting control unit 5 instead of the shock relay 85. In this case, for example, the thermal relay is attached to the unit frame 35 at the same position as the shock relay 85 in the examples of FIGS. 4 and 5. The thermal relay outputs a signal to the control circuit of the circuit board 81 in response to the occurrence of overcurrent in the lifting drive unit 3 for a certain period of time and the generation of heat due to the overcurrent in the lifting drive unit 3. Then, in the lifting control unit 5, the control circuit of the circuit board 81 cuts off the current supplied to the lifting drive unit 3 in response to the transmission of a signal from the thermal relay. Also, when a thermal relay is provided, in one example, the thermal relay may be directly attached to the lower part of the current direction switching unit 72. In this case, the thermal relay is attached to the current direction switching unit 72 from the lower side in the height direction of the lifting control unit 5.
[0073] In the lifting control unit 5, a number of wirings (not shown) extend between the plate member 36 and the rear plate portion 45 of the unit frame 35. The wirings extending between the plate member 36 and the rear plate portion 45 of the unit frame 35 include the wirings that electrically connect the current cutoff unit 71 to the current direction switching unit 72 and the shock relay 85 respectively. In particular, a number of wirings are used for the electrical connection between the current cutoff unit 71 and the current direction switching unit 72. Also, the circuit board 81 is electrically connected to each of the current cutoff unit 71, the current direction switching unit 72, the shock relay 85, etc. via wirings. Note that, in one example, at least a part of the wirings extending between the plate member 36 and the rear plate portion 45 of the unit frame 35 may be attached to either of the side frame portions 41, 42 in a bundled state.
[0074] FIG. 7 shows a perspective view of the lifting control unit 5 according to the embodiment, omitting the current direction switching unit 72 and the shock relay 85. As shown in FIG. 7 and the like, a rail 88 is attached to the front surface 67 of the rear plate portion 45 of the unit frame 35. In an example of FIGS. 4, 5, and 7, the current direction switching unit 72 and the shock relay 85 are attached to the rear plate portion 45 with the rail 88 interposed therebetween. The rail 88 is, for example, a DIN rail. In one example, a rail similar to the rail 88 may be attached to the front surface 57 of the plate member 36, and the current cutoff unit 71 may be attached to the plate member 36 with the rail interposed therebetween.
[0075] In addition, a CP (circuit protector) 86 and a connector 87 are mounted on the lifting control unit 5. The CP 86 cuts off the supply of current to the downstream side in response to the occurrence of an overcurrent or the like on the downstream side of the CP 86. Further, wiring from the outside of the lifting control unit 5 is connected to the connector 87. In an example of FIGS. 3, 5, and 7, the CP 86 and the connector 87 are attached to the front surface 57 of the plate member 36 and are attached to the bottom portion 66 of the recess 65 in the plate member 36. However, in one example, each of the CP 86 and the connector 87 may be attached to any one of the rear plate portion 45 and the side frame portions 41, 42.
[0076] As described above, in this embodiment, in the lifting control unit 5, the current cutoff unit 71 is attached to the front surface 57 of the plate member 36, and the current direction switching unit 72 is disposed on the rear side with respect to the plate member 36 and the current cutoff unit 71. Thereby, it becomes possible to reduce the size of the lifting control unit 5 in the height direction as compared with a configuration in which both the current cutoff unit 71 and the current direction switching unit 72 are attached to the front surface 57 of the plate member 36. Therefore, it is possible to provide a lifting control unit 5 in which the current cutoff unit 71, the current direction switching unit 72, etc. are disposed at appropriate positions in a state where the dimensions in the height direction are reduced.
[0077] By reducing the dimensions of the lifting control unit 5 along the height direction, it becomes possible to increase the number of lifting control units 5 implemented on the lifting control panel 10 without increasing the dimensions of the lifting control panel 10. Therefore, even when there are restrictions on the space where the lifting control panel 10 is arranged, it becomes possible to increase the number of lifting control units 5 implemented on the lifting control panel 10.
[0078] In one example, in a configuration where both the current cutoff part 71 and the current direction switching part 72 are attached to the front surface 57 of the plate member 36, the dimension of the lifting control unit 5 along the height direction is 280 mm, whereas in the configuration where the current cutoff part 71 and the current direction switching part 72 are arranged as in the present embodiment, the dimension of the lifting control unit 5 along the height direction is 210 mm. Therefore, by arranging the current cutoff part 71 and the current direction switching part 72 as in the present embodiment, the dimension of the lifting control unit 5 along the height direction is reduced by 21% compared to the configuration where both the current cutoff part 71 and the current direction switching part 72 are attached to the front surface 57 of the plate member 36. In this case, in the lifting control panel 10, it becomes possible to mount 24 lifting control units 5 of the present embodiment in the space where 20 lifting control units of the configuration where both the current cutoff part 71 and the current direction switching part 72 are attached to the front surface 57 of the plate member 36 were mounted.
[0079] Also, in the present embodiment, the current cutoff part 71 is attached to the front surface 57 of the plate member 36. Therefore, users of the lifting control unit 5 and the lifting control panel 10 can easily operate the current cutoff part 71. Thereby, users of the lifting control unit 5 and the lifting control panel 10 can easily perform operations such as cutting off the current by operating the current cutoff part 71.
[0080] In addition, in the present embodiment, the plate member 36 rotates about the attachment position to the unit frame 35 as the rotation center, thereby performing an opening and closing operation with respect to the unit frame 35. The current interruption unit 71 rotates with respect to the unit frame 35 together with the plate member 36 in response to the opening and closing operation of the plate member 36. Due to such a configuration, by opening the plate member 36 with respect to the unit frame 35, it becomes possible to check the operating conditions of the current direction switching unit 72 and the like arranged on the rear side with respect to the plate member 36. Also, users of the lifting control unit 5 and the lifting control panel 10 can access the current direction switching unit 72 and the like without removing the current direction switching unit 72 and the like from the unit frame 35 by opening the plate member 36 with respect to the unit frame 35. That is, by opening the plate member 36 with respect to the unit frame 35, it is possible to secure a working space accessible to the current direction switching unit 72 and the like. As a result, in the current direction switching unit 72 and the like arranged on the rear side with respect to the plate member 36, it becomes easier to perform component replacement work, wiring work, and the like.
[0081] Also, in an example of the present embodiment, in the unit frame 35, the plate member 36 is rotatably attached to the side frame portion 41, and the current direction switching unit 72 is arranged between the side frame portions 41 and 42 in the width direction. And the current direction switching unit 72 is arranged at a position closer to the side frame portion (first side frame portion) 41 than the side frame portion (second side frame portion) 42. By adopting such a configuration, even when the plate member 36 is opened with respect to the unit frame 35, the separation distance between the current interruption unit 71 and the current direction switching unit 72 does not increase. As a result, it becomes unnecessary to lengthen the numerous wirings that electrically connect between the current interruption unit 71 and the current direction switching unit 72. Since the wiring between the current interruption unit 71 and the current direction switching unit 72 does not become longer, in a state where the plate member 36 is closed with respect to the unit frame 35 or the like, it is effectively prevented that the numerous wirings between the current interruption unit 71 and the current direction switching unit 72 are bent or the like.
[0082] Further, in the present embodiment, since the side frame portions 41 and 42 are provided on the unit frame 35, the strength of the unit frame 35 is ensured, and the strength of the lifting control unit 5 is appropriately ensured. Also, the wiring extending between the rear plate portion 45 of the unit frame 35 and the plate member 36 can be attached to the side frame portions 41 and 42 in a bundled state.
[0083] Also, in an example of the present embodiment, the attachment plate 73 is detachably attached to the unit frame 35, and the circuit board 81 mounted on the attachment plate 73 is attached to the unit frame 35 with the attachment plate 73 interposed therebetween. With such a configuration, users of the lifting control unit 5 and the lifting control panel 10 can remove the attachment plate 73 from the unit frame 35 and then move the attachment plate 73 from the position where it was attached to the unit frame 35 to the front side of the lifting control unit 5, and the circuit board 81 can be replaced. This makes it easier to perform the replacement work of the circuit board 81.
[0084] Also, in an example of the present embodiment, a recess 65 that is recessed toward the side where the rear surface 58 faces with respect to the attachment position to the unit frame 35 is formed in the plate member 36. And the current cut-off portion 71 is attached to the plate member 36 in the recess 65. With such a configuration, the protruding amount of the current cut-off portion 71 toward the side where the front surface 57 of the plate member 36 faces is reduced. Thereby, in the lifting control panel 10, interference of the current cut-off portion 71 with units and the like arranged around the lifting control unit 5 is effectively prevented. In particular, interference of the current cut-off portion 71 with another lifting control unit 5 arranged adjacent in the width direction of the lifting control module 11 is effectively prevented in a state where the plate member 36 is opened with respect to the unit frame 35 and the like.
[0085] Also, in one example of this embodiment, the current direction switching unit 72 and the shock relay 85 are attached to the rear plate portion 45 with a rail 88 such as a DIN rail interposed therebetween. By adopting such a configuration, it becomes possible to attach a plurality of types of current direction switching units 72 with different screw hole positions and the like to the rear plate portion 45 without replacing the rear plate portion 45. Therefore, even when replacing the current direction switching unit 72 with a type different from the attached type, it is not necessary to replace the rear plate portion 45. Also, regarding the current cutoff unit 71, by adopting a configuration in which it is attached to the plate member 36 with a rail similar to the rail 88 interposed therebetween, it becomes possible to attach a plurality of types of current cutoff units 71 with different screw hole positions and the like to the plate member 36 without replacing the plate member 36.
[0086] Hereinafter, modifications of the above-described embodiments and the like will be described. FIG. 8 is a perspective view showing the configuration of the lifting control unit 5 according to a modification of the embodiment. As shown in FIG. 8, also in this modification, the lifting control unit 5 includes a unit frame 35, a plate member 36, a current cutoff unit 71, a current direction switching unit 72, a circuit board 81, and the like, similar to the above-described embodiments and the like. And the circuit board 81 including the wiring board 82 is disposed below the plate member 36, the rear plate portion 45, the current cutoff unit 71, and the current direction switching unit 72 in the height direction of the lifting control unit 5.
[0087] FIG. 9 is a perspective view showing the lifting control unit 5 of the modification of FIG. 8 with the plate member 36, the current cutoff unit 71, and the like omitted. FIGS. 10 and 11 show the circuit board 81 of the lifting control unit 5 of the modification of FIG. 8. FIG. 10 shows a perspective view, and FIG. 11 shows a plan view viewed from the upper side in the height direction. As shown in FIGS. 8 to 11 and the like, in the circuit board 81, the wiring board 82 is formed in a plate shape, and in the wiring board 82, the plate thickness direction is defined. The wiring board 82 is disposed in a state where the plate thickness direction is along the height direction of the lifting control unit 5.
[0088] The wiring board 82 includes a board upper surface 91 and a board lower surface 92 as a pair of main surfaces. The board upper surface 91 faces one side in the thickness direction of the wiring board 82 and faces the upper side in the height direction of the lifting control unit 5. The board lower surface 92 faces the side opposite to the side that the board upper surface 91 of the wiring board 82 faces, and faces the lower side in the height direction of the lifting control unit 5. In the circuit board 81, a plurality of electronic components are mounted on the board upper surface 91 of the wiring board 82. Each of the electronic components is installed on the board upper surface 91 from the upper side in the height direction of the lifting control unit 5.
[0089] In this modified example, the plurality of electronic components mounted on the wiring board 82 include a plurality of types of relays 93, a front connector 95, a rear connector 96, a side connector 97, and circuit components 98. Each of the relays 93 has electrical contacts and performs a switching operation of switching the transmission state of an electrical signal, such as switching the opening and closing of the electrical contacts, based on an external operation signal or detection signal. In this modified example, as the plurality of types of relays 93, two types of relays 93A and 93B are provided. The relay 93A is different from the relay 93B in external shape and protrusion height from the board upper surface 91. Therefore, the plurality of types of relays 93A and 93B are different in external shape for each type and different in protrusion height from the board upper surface 91 for each type.
[0090] In one example of FIGS. 8 to 11, the protruding height of relay 93A from the upper surface 91 of the substrate is higher than that of relay 93B from the upper surface 91 of the substrate. Therefore, among the plurality of types of relays 93A and 93B, relay 93A becomes the highest protruding relay, which is the type with the highest protruding height from the upper surface 91 of the substrate. Also, in one example of FIGS. 8 to 11, seven relays 93A, which are the highest protruding relays, are provided, and five relays 93B are provided. On the upper surface 91 of the wiring substrate 82, each of the relays 93A, which are the highest protruding relays, is arranged on the front side of the lifting control unit 5 with respect to any of the other types of relays 93B. Therefore, among the plurality of types of relays 93A and 93B, relay 93A, which is the highest protruding relay, is arranged on the most front side. Since the plurality of types of relays 93A and 93B are arranged as described above, in one example of FIGS. 8 to 11, the relays 93 of the type with a higher protruding height are arranged more on the front side of the lifting control unit 5.
[0091] In one example, three or more types of relays 93 with different protruding heights from the upper surface 91 of the substrate are mounted on the upper surface 91 of the wiring substrate 82. Also in this case, each of the highest protruding relays, which are the types with the highest protruding height from the upper surface 91 of the substrate, is arranged on the front side of the lifting control unit 5 with respect to any of the other types of relays. Therefore, among the plurality of types of relays 93, the highest protruding relay is arranged on the most front side.
[0092] In the case where three or more types of relays 93 with different protruding heights from each other are mounted on the wiring substrate 82, it is preferable that the relays 93 of the type with a higher protruding height from the upper surface 91 of the substrate are arranged more on the front side. In this case, each of the relays of the type with the lowest protruding height is arranged on the rear side of the lifting control unit 5 with respect to any of the other types of relays.
[0093] However, in this modified example, if the highest protruding relay is arranged on the foremost side, the arrangement of relays 93 of types other than the highest protruding relay is not particularly limited. For example, in a configuration where three or more types of relays 93 are mounted on the wiring board 82, if the highest protruding relay is arranged on the foremost side, a configuration may be adopted in which the relay of the type with the second lowest protruding height is arranged on the rearmost side.
[0094] Also, in this modified example, the same number of sockets 101 as the number of relays 93 are mounted on the wiring board 82, and one socket 101 is provided for each of the relays 93. Each of the sockets 101 is attached to the upper surface 91 of the board by soldering or the like. Each of the relays 93 is mounted on the wiring board 82 by being inserted into one corresponding socket 101. Also, each of the relays 93 is removed from the wiring board 82 by being pulled out from one corresponding socket 101.
[0095] In this modified example, one or more relay rows 90A are formed in which a plurality of relays 93A of the same type are arranged in the width direction of the lifting control unit 5. In an example of FIGS. 8 to 11, two relay rows 90A1 and 90A2 are formed as the relay row 90A. In the relay row 90A1, four relays 93A are arranged in the width direction, and in the relay row 90A2, three relays 93A are arranged in the width direction. Also, among the relays 93 mounted on the wiring board 82, the four relays 93A forming the relay row 90A1 are arranged on the foremost side. Also, in each of the relay rows 90A, each of the relays 93A has a gap between adjacent relays 93A in the width direction that allows a finger to be inserted.
[0096] In this modification example, one or more relay columns 90B in which a plurality of relays 93B of the same type are arranged in the width direction of the lifting control unit 5 are formed. In an example of FIGS. 8 to 11, one relay column 90B1 is formed as the relay column 90B. In the relay column 90B1, five relays 93B are arranged in the width direction. Among the relays 93 mounted on the wiring board 82, the five relays 93B forming the relay column 90B1 are arranged on the rearmost side. Further, in the relay column 90B, each of the relays 93B has a gap between adjacent relays 93B in the width direction that allows a finger to be inserted.
[0097] Also, in this modification example, a plurality of relays 93A of the same type are mounted on the wiring board 82 in a state where their directions are aligned with each other, that is, in the same or substantially the same posture with respect to each other. In an example of FIGS. 8 to 11, each of the plurality of relays 93A is mounted on the wiring board 82 in a posture where the surface 102 faces the upper side in the height direction of the lifting control unit 5 and the surface 103 faces the arrow Y4 side in the width direction of the lifting control unit 5.
[0098] Also, in this modification example, a plurality of relays 93B of the same type are mounted on the wiring board 82 in a state where their directions are aligned with each other, that is, in the same or substantially the same posture with respect to each other. In an example of FIGS. 8 to 11, each of the plurality of relays 93B is mounted on the wiring board 82 in a posture where the surface 105 faces the upper side in the height direction of the lifting control unit 5 and the surface 106 faces the front side of the lifting control unit 5.
[0099] Further, the plurality of relays 93 are classified into a plurality of groups from the viewpoint of the use for switching operation. The plurality of groups are set based on the use for switching operation and are set from a different viewpoint from the above-described types. Among the plurality of relays 93, the use for switching operation is different for each group. In this modification example, on the upper surface 91 of the wiring board 82, the plurality of relays 93 are grouped and arranged in one area for each group.
[0100] In an example such as FIG. 11, from the perspective of the use for switching operations, a plurality of relays 93 are classified into four groups: a group collectively arranged in region α1, a group collectively arranged in region α2, a group collectively arranged in region α3, and a group collectively arranged in region α4. Each of the six relays 93 belonging to the group arranged in region α1 performs a switching operation, for example, based on a detection signal detecting an alarm. Also, each of the two relays 93 belonging to the group arranged in region α2 performs a switching operation, for example, based on an operation signal from an operation panel for backup. And each of the two relays 93 belonging to the group arranged in region α3 performs a switching operation, for example, based on an operation signal from an operating device.
[0101] Also, on the upper surface 91 of the wiring board 82, the front connector 95 is arranged at the front end and is mounted on the front side of the lifting control unit 5 for any of the plurality of types of relays 93. For this reason, the relay 93A arranged on the foremost side among the plurality of types of relays 93 is also located on the rear side with respect to the front connector 95. In an example of FIGS. 8 to 11, four front connectors 95A to 95D are mounted on the wiring board 82 as the front connector 95. Wires are connected by inserting wires from the front side of the lifting control unit 5 into each of the front connectors 95. The plurality of front connectors 95 are arranged side by side in the width direction of the lifting control unit 5. Also, each of the plurality of front connectors 95 is arranged apart from the adjacent front connector 95 in the width direction. In an example of FIGS. 8 to 11, they are arranged in the order of front connectors 95A, 95C, 95D, 95B from the arrow Y3 side in the width direction.
[0102] Wiring for supplying power is connected to each of the front connectors 95A and 95B, and each of the front connectors 95A and 95B is connected to the aforementioned terminal block installed on the panel frame 12 via the wiring. The lifting control unit 5 is transported to the use site while being attached to the panel frame 12 of the lifting control panel 10. Wiring is connected to each of the front connectors 95A and 95B, for example, at a factory or the like, before the lifting control panel 10 including the lifting control unit 5 is transported to the use site. Also, the wirings connected to the front connectors 95A and 95B supply power at different voltages from each other. In one example, power is supplied at a voltage of 100V through the wiring connected to the front connector 95A, and power is supplied at a voltage of 24V or less through the wiring connected to the front connector 95B.
[0103] Signal lines or the like for transmitting electrical signals are connected as wiring to each of the front connectors 95C and 95D. Wiring is connected to each of the front connectors 95C and 95D at the use site such as a stage after the lifting control panel 10 including the lifting control unit 5 is transported to the use site. Each of the front connectors 95C and 95D is connected to the lifting drive unit 3 of the corresponding baton 1 via the wiring. Also, the wirings connected to the front connectors 95C and 95D transmit electrical signals at different voltages from each other. In one example, an electrical signal is transmitted at a voltage of 100V through the wiring connected to the front connector 95C, and an electrical signal is transmitted at a voltage of 24V or less through the wiring connected to the front connector 95D.
[0104] Also, on the upper surface 91 of the wiring board 82, the rear connector 96 is disposed at the rear end and is mounted on the rear side of the lifting control unit 5 for any of the plurality of types of relays 93. Therefore, even the relay 93B disposed most rearward among the plurality of types of relays 93 is located on the front side with respect to the rear connector 96. In an example of FIGS. 8 to 11, three rear connectors 96A to 96C are mounted on the wiring board 82 as the rear connector 96. Wiring is connected to each of the rear connectors 96 by inserting wiring from the rear side of the lifting control unit 5. The plurality of rear connectors 96 are arranged side by side in the width direction of the lifting control unit 5. Also, each of the plurality of rear connectors 96 is arranged apart from the adjacent rear connector 96 in the width direction. In an example of FIGS. 8 to 11, they are arranged in the order of rear connectors 96A, 96B, 96C from the side of the arrow Y3 in the width direction.
[0105] Signal lines or the like for transmitting electrical signals are connected as wiring to each of the rear connectors 96A to 96C, and each of the rear connectors 96A to 96C is connected to the aforementioned terminal block installed on the panel frame 12 with the wiring interposed therebetween. Wiring is connected to each of the rear connectors 96A to 96C, for example, at a factory or the like before the lifting control panel 10 including the lifting control unit 5 is transported to the site of use. Also, in the wiring connected to the rear connector 96A, electrical signals are transmitted at different voltages with respect to each of the wirings connected to the rear connectors 96B and 96C. In one example, an electrical signal is transmitted at a voltage of 100V through the wiring connected to the rear connector 96A, and an electrical signal is transmitted at a voltage of 24V or less through each of the wirings connected to the rear connectors 96B and 96C.
[0106] Also, on the upper surface 91 of the wiring board 82, the side connector 97 is mounted at one end in the width direction, and in an example of FIGS. 8 to 11, it is arranged on the arrow Y4 side in the width direction with respect to any electronic component including the relay 93, the front connector 95, the rear connector 96, and the circuit component 98. Also, in an example of FIGS. 8 to 11, the side connector 97 is arranged on the rear side with respect to the front connector 95 and the relay 93A which is the highest protruding relay. In an example of FIGS. 8 to 11, three side connectors 97A to 97C are mounted on the wiring board 82 as the side connector 97. The plurality of side connectors 97 are arranged side by side in the front-rear direction of the lift control unit 5. Also, each of the plurality of side connectors 97 is arranged at a distance from the adjacent side connector 97 in the front-rear direction. In an example of FIGS. 8 to 11, they are arranged in the order of side connectors 97A, 97B, 97C from the rear side.
[0107] As the side connector 97, a connector smaller than the front connector 95 and the rear connector 96 is used. Also, as the side connector 97, a top-type connector is used, and wiring is connected to each of the side connectors 97 by inserting the wiring from the upper side in the height direction of the lift control unit 5. Wiring for data writing and the like can be connected to the side connector 97C. The wiring is not connected to the side connector 97C during the use of the lift control unit 5 and the like.
[0108] In the lifting control panel 10, as described above, a plurality of lifting control units 5 are attached to the panel frame 12. In the lifting control unit 5, communication lines used for communication with other lifting control units 5 attached to the panel frame 12 can be connected as wiring to the side connectors 97A and 97B respectively. For example, when N lifting control units 5 are attached to the panel frame 12, in each of the (N - 2) lifting control units 5, the side connector 97A is connected to one of the other lifting control units 5 via a communication line, and the side connector 97B is connected to another one different from the connection destination of the side connector 97A among the other lifting control units 5 via a communication line. Also, in one of the remaining two lifting control units 5, one of the side connectors 97A and 97B is connected to one of the other lifting control units 5 via a communication line, and the other of the side connectors 97A and 97B is connected to a device outside the lifting control panel 10 such as a device via a communication line. And in the other of the remaining two lifting control units 5, one of the side connectors 97A and 97B is connected to one of the other lifting control units 5 via a communication line, and no wiring such as a communication line is connected to the other of the side connectors 97A and 97B.
[0109] Also, in an example of FIGS. 8 to 11, the front connectors 95A, 95C and the rear connector 96A are colored the same specific color with respect to each other. And connectors other than the front connectors 95A, 95C and the rear connector 96A are colored a color other than the specific color. In one example, the specific color is orange. Thereby, connectors that are connection destinations of wiring for supplying power at a voltage of 100V or for transmitting an electrical signal at a voltage of 100V are colored the specific color, and connectors that are connection destinations of wiring for supplying power at a voltage of 124V or less or for transmitting an electrical signal at a voltage of 24V or less are colored a color other than the specific color.
[0110] The circuit component 98 constitutes a microcomputer or an integrated circuit. In the circuit component 98, the protruding height from the upper surface 91 of the substrate is lower than that of any of the relays 93 (93A, 93B). Therefore, in the circuit component 98, the protruding height is lower than that of the relay 93B having the lowest protruding height among the plurality of types of relays 93A and 93B.
[0111] On the upper surface 91 of the wiring board 82, the circuit component 98 is arranged near the side connector 97. And the circuit component 98 is arranged at a position closer to the side connector 97 than any of the relays 93. In an example of FIGS. 8 to 11, the circuit component 98 is arranged between the relay row 90B and the side connector 97 in the width direction of the lifting control unit 5. For this reason, the relay 93B is mounted on the side opposite to the side where the side connector 97 is located with respect to the circuit component 98. Also, in an example of FIGS. 8 to 11, the circuit component 98 is arranged between the relay row 90A2 and the side connector 97 in the width direction of the lifting control unit 5. And the circuit component is arranged on the rear side with respect to the relay row 90A1, and is arranged on the rear side with respect to the relay 93 on the frontmost side among the plurality of relays 93.
[0112] In addition, in an example, on the upper surface 91 of the wiring board 82, the side connector 97 is mounted at the end on the arrow Y3 side in the width direction. Also in this case, the circuit component 98 is arranged near the side connector 97. And the circuit component 98 is arranged at a position closer to the side connector 97 than any of the relays 93. In this example, the relay 93, the side connector 97, and the circuit component 98 are arranged, for example, in a state inverted in the width direction of the lifting control unit 5 from an example of FIGS. 8 to 11.
[0113] Even in the modified examples shown in FIGS. 8 to 11, the same operations and effects as those in the above-described embodiments and the like are exhibited. That is, also in this modified example, it becomes possible to reduce the size of the lifting control unit 5 along the height direction. Therefore, it becomes possible to provide the lifting control unit 5 in which the current cutoff unit 71, the current direction switching unit 72, etc. are arranged at appropriate positions in a state where the dimension along the height direction is reduced.
[0114] Also, in the lifting control unit 5 of this modified example, a wiring board 82 is disposed below the plate member 36, the current cutoff unit 71, and the current direction switching unit 72 in the height direction. A plurality of types of relays 93A and 93B having different protruding heights from the upper surface 91 of the board for each type are disposed on the upper surface 91 of the wiring board 82. Among the plurality of types of relays 93A and 93B, the highest protruding relay (93A), which is the type with the highest protruding height, is disposed on the most front side. By adopting such a configuration, it becomes possible to realize a configuration in which on the upper surface 91 of the wiring board 82, electronic components with a high protruding height such as the highest protruding relay are not disposed in the rear region.
[0115] On the upper surface 91 of the board, since electronic components with a high protruding height are not disposed in the rear region, a certain separation distance is ensured between the current direction switching unit 72, the shock relay 85, etc. and the electronic components of the circuit board 81. Thereby, contact of the wiring connected to the current direction switching unit 72, the shock relay 85, etc. with the electronic components of the circuit board 81 is effectively prevented, and at the time of manufacturing the lifting control unit 5, etc., a wide space for performing the wiring connection work to the current direction switching unit 72, the shock relay 85, etc. can be secured.
[0116] Also, in one example of this modified example, on the upper surface 91 of the board, the relays 93 of the type with a higher protruding height are disposed more on the front side. Thereby, a configuration in which electronic components with a high protruding height are not disposed in the rear region on the upper surface 91 of the wiring board 82 is more appropriately realized. Also, in one example of this modified example, each of the relays 93 is mounted on the wiring board 82 by being inserted into one corresponding socket 101. And each of the relays 93 has a gap that allows a finger to be inserted between adjacent relays 93. Thereby, it becomes easier to mount the relay 93 on the wiring board 82 and also easier to remove the relay 93 from the wiring board 82. Therefore, the labor in replacing the relay 93, etc. is reduced.
[0117] Also, in one example of this modification, a plurality of relays 93 of the same type are mounted on the wiring board 82 in a state where their directions are aligned with each other, that is, in the same or substantially the same posture with respect to each other. For this reason, it becomes difficult to misalign the posture (direction) for attaching the relay 93 to the wiring board 82.
[0118] Also, on the upper surface 91 of the wiring board 82, circuit components 98 that constitute a microcomputer or the like are arranged in a state of being concentrated at one location, and are arranged on the rear side with respect to the relay 93 on the frontmost side among the plurality of relays 93. And, among the circuit components 98, the protruding height from the upper surface 91 of the board is lower than that of any of the relays 93. As a result, contact of the wiring connected to the current direction switching unit 72, the shock relay 85, etc. with the electronic components of the circuit board 81 is more effectively prevented, and at the time of manufacturing the lifting control unit 5 or the like, a space for performing the connection work of the wiring to the current direction switching unit 72, the shock relay 85, etc. can be ensured more widely.
[0119] Also, in one example of this modification, the front connector 95 is arranged on the front side with respect to any of the plurality of types of relays 93 on the upper surface 91 of the wiring board 82, and wiring is inserted into the front connector 95 from the front side. By adopting such a configuration, at the place where the lifting control unit 5 is used, a constructor or the like can connect the wiring to the front connector 95 without removing the circuit board 81 from the unit frame 35. Also, when it becomes necessary to cut off the power supply to the lifting control unit 5, the wiring can be easily and instantaneously removed from the front connector 95.
[0120] Also, in one example of this modification, the circuit component 98 is arranged at a position close to the side connector 97 with respect to any of the relays 93. As a result, the circuit component 98 can be arranged close to the side connector 97 to which the communication line used for communication with the other lifting control unit 5 is connected. Wiring is inserted into each of the side connectors 97 from the upper side in the height direction of the lifting control unit 5. This makes it easier to connect wiring and the like to the side connector 97 mounted at one end in the width direction on the upper surface 91 of the substrate. Also, in one example of this modification, the connectors that are the connection destinations of the wiring for supplying power at a voltage of 100V or the wiring for transmitting an electrical signal at a voltage of 100V are colored in a specific color, and the connectors that are the connection destinations of the wiring for supplying power at a voltage of 124V or less or the wiring for transmitting an electrical signal at a voltage of 24V or less are colored in a color other than the specific color. Thereby, for each of the connectors 95, 96, 97, it becomes possible to grasp the voltage used in the connected wiring.
[0121] According to at least one of these embodiments, in the lifting control unit of the baton, a current interruption part is attached to the front surface of the plate member, and the current direction switching part is arranged on the rear side with respect to the plate member and the current interruption part. Thereby, it is possible to provide a lifting control unit of a baton capable of reducing the dimension along the height direction, and a lifting control panel of a baton including the lifting control unit.
