The support portion 94d is disposed at a position facing the gear 90 and a position facing the pinion gear 94b. As a result, the rack 94c is sandwiched between the support portion 94d and the gear 90, and is sandwiched between the support portion 94d and the pinion gear 94b, and the state of meshing with the teeth of the gear 90 and the pinion gear 94b is maintained.

The second arm 88 is supported in a state in which a tip extending in one direction from the rotation shaft 88a is slidable on the rail 89b. The rail 89b is fixed to the elevating movable unit 70 and extends in the horizontal direction. The second arm 88 rotates in synchronization with the rotation of the connecting portion 94a. As the second arm 88 rotates, the position of the tip in the vertical direction moves. The rail 89b in which the tip of the second arm 88 is inserted moves in the vertical direction integrally with the tip while sliding the tip in the horizontal direction.

  The first auxiliary arm 96 is arranged in a line extending from the rotation shaft 86 a of the first arm 86.

The bearing 120 is fixed to the base body 80. The first auxiliary arm 96 is supported in a state in which a tip extending in one direction from the rotating shaft can slide on the rail 89c. The rail 89c has the same structure as the rail 89a. The first auxiliary arm 96 rotates in synchronization with the first arm 86 connected by the first connecting shaft 98. As the first auxiliary arm 96 rotates, the position of the tip in the vertical direction moves. The rail 89c into which the distal end portion of the first auxiliary arm 96 is inserted moves in the vertical direction integrally with the distal end portion while sliding the distal end portion in the horizontal direction.

  The second auxiliary arm 97 is arranged in an extension line of the rotation shaft 88 a of the second arm 88. The second auxiliary arm 97 is connected to the rotation shaft 88 a of the second arm 88 by the second connection shaft 99. The second connecting shaft 99 is rotatably supported by the bearing 120.

As the second auxiliary arm 97 rotates, the position of the tip in the vertical direction moves. The rail 89d into which the tip of the second auxiliary arm 97 is inserted moves in the vertical direction integrally with the tip while sliding the tip in the horizontal direction.

  The power transmission mechanism 84 of the elevating mechanism 54 shown in FIG. 7 is arranged such that the tips of the first arm 86 and the second arm 88 are higher than the rotation shafts 86a and 88a. When the gear 90 rotates in the direction of arrow 130 (counterclockwise in FIG. 7) following the rotation of the drive source 82, the lifting device 54 shown in FIG. 7 has a pinion gear 92b in which the rack 92c is in the direction of arrow 132. The end of the side rack 92c moves away from the gear 90. When the rack 92c moves in the direction of the arrow 132, the pinion gear 92b, the first arm 86, and the first auxiliary arm 96 rotate in the direction of the arrow 134 (counterclockwise in FIG. 7). Further, when the gear 90 rotates in the direction of arrow 130 (counterclockwise in FIG. 7) following the rotation of the drive source 82, the power transmission mechanism 84 is on the pinion gear 94b side where the rack 94c is in the direction of arrow 136. The end of the rack 94c moves in a direction away from the gear 90. When the rack 94c moves in the direction of the arrow 136, the pinion gear 94b, the second arm 88, and the second auxiliary arm 97 rotate in the direction of the arrow 138 (clockwise in FIG. 7). Thus, the power transmission mechanism 84 rotates the first arm 86, the second arm 88, the first auxiliary arm 96, and the second auxiliary arm 97 in conjunction with the rotation of the gear 90, thereby rotating the rails 89a, 89b, The tip portions inserted into 89c and 89d are moved downward in the vertical direction, and the lift movable unit 70 to which the rails 89a, 89b, 89c and 89d are fixed is moved downward in the vertical direction indicated by the arrow 139.

When the gear 90 rotates in the direction of the arrow 140 (clockwise in FIG. 8) following the rotation of the drive source 82, the lifting device 54 shown in FIG. 8 is on the pinion gear 92b side where the rack 92c is in the direction of the arrow 142. The end of the rack 92c moves in a direction approaching the gear 90. When the rack 92c moves in the direction of the arrow 142, the pinion gear 92b, the first arm 86, and the first auxiliary arm 96 rotate in the direction of the arrow 144 (clockwise in FIG. 8). Further, when the gear 90 rotates in the direction of the arrow 140 (clockwise in FIG. 8) following the rotation of the drive source 82, the power transmission mechanism 84 is on the pinion gear 94b side where the rack 94c is in the direction of the arrow 146. The end of the rack 94c moves in a direction approaching the gear 90. When the rack 94c moves in the direction of the arrow 146, the pinion gear 94b, the second arm 88, and the second auxiliary arm 97 rotate in the direction of the arrow 148 (counterclockwise in FIG. 8). Thus, the power transmission mechanism 84 rotates the first arm 86, the second arm 88, the first auxiliary arm 96, and the second auxiliary arm 97 in conjunction with the rotation of the gear 90, thereby rotating the rails 89a, 89b, The tip portions inserted into 89c and 89d are moved upward in the vertical direction, and the up-and-down movable unit 70 to which the rails 89a, 89b, 89c and 89d are fixed is moved upward in the vertical direction indicated by the arrow 149.

  The guide mechanism 74 is disposed at two positions apart from each other. The guide mechanism 74 restricts relative movement of the elevating movable unit 70 and the elevating drive unit 72 in the horizontal plane. The guide mechanism 74 includes a guide rod 102 and a shoe 104. The guide rod 102 is a rod-like member fixed to the base body 80 and extends in the vertical direction. The shoe 104 is fixed to the elevating movable unit 70, and a guide bar 102 is inserted therein. The guide mechanism 74 is configured to move the shoe 104 along the guide rod 102, thereby restricting relative movement of the elevating movable unit 70 and the elevating drive unit 72 in the horizontal plane. The raising / lowering movable unit 70 is prevented from moving in the horizontal direction with respect to the raising / lowering driving unit 72.

  The sensor unit 76 is a device that detects the position of the elevating movable unit 70 of the elevating mechanism 54. The sensor unit 76 detects the position of the elevating movable unit 70 of the elevating mechanism 54 based on the position of the rack 94c. The sensor unit 76 includes a sensor 76a and a sensor 76b. The sensors 76a and 76b detect the position of the rack 94c by detecting whether or not they are in contact with a striker provided at a predetermined position of the rack 94c. The sensors 76a and 76b are disposed at positions where the striker contacts one of the sensors when the rack 94c moves to both ends of the moving range. The sensor 76a has a detection terminal 150a operating at the tip. As shown in FIG. 9, the sensor 76 a does not output a signal when the contact terminal 150 a is at the solid line position, and outputs a detection signal when the striker 160 contacts the contact terminal 150 a and moves to the dotted line position. As shown in FIG. 10, the sensor 76b does not output a signal when the contact terminal 150b is at the solid line position, and outputs a detection signal when the striker 160 contacts the contact terminal 150b and moves to the dotted line position. The elevating mechanism 54 controls the operation of the elevating drive unit 72 and the position of the elevating movable unit 70 based on the detection result of the sensor unit 76.

  In the swivel device 16, the elevating mechanism 54 transmits the power of one drive source 82 to the first arm 86 and the second arm 88 by the first transmission unit 92 and the second transmission unit 94 using a rack and pinion mechanism. By moving the first arm 86 and the second arm 88 that are slidably connected to the lift movable unit 70, the lift movable unit 70 is lifted and lowered. As a result, the elevating movable unit 70 can be moved up and down by the rotation of the first arm 86 and the second arm 88 while the elevating movable unit 70 is supported by the first arm 86 and the second arm 88. Thereby, since it can raise / lower while supporting the rotation mechanism 52, the turning apparatus 16 can be made into a simple structure. That is, by using an arm that is a rigid body that transmits power, the load can be supported without providing another mechanism for supporting the load, and the configuration can be simplified. In addition, by transmitting power with the rack and pinion mechanism, the arm position can be supported at a predetermined position without applying tension as in a chain.

  The transmission mechanism of the present embodiment uses a rack and pinion mechanism. However, if the rotational motion can be converted into a linear motion and then transmitted to the first arm 86 and the second arm 88, another mechanism can be used. Also good. Further, the swivel device 16 can support the elevating movable unit 70 at four points by providing the first auxiliary arm 96, the second auxiliary arm 97, the first connecting shaft 98, and the second connecting shaft 99. Thereby, the raising / lowering movable part 70 can be supported more stably.
