Overhead conveying vehicle
In an overhead conveying vehicle, a main body to hold a conveyed object is suspended and supported by a conveyor. The overhead conveying vehicle includes: a base unit suspended from the conveyor, a support part in the main body to rotatably support the base unit via a turning shaft extending in a horizontal direction, and a pair of dampers sandwiching the turning shaft in a second direction perpendicular or substantially perpendicular to both the first direction in which the turning shaft extends and the vertical direction, and movable to contact with the main body.
1 . An overhead conveying vehicle comprising:
a main body to hold a conveyed object suspended and supported by a conveyor;
a base suspended by the conveyor;
a support provided on the main body to rotatably support the base via a turning shaft extending in a horizontal direction; and
a pair of dampers provided on the base to sandwich the turning shaft in a second direction perpendicular or substantially perpendicular to both of a first direction in which the turning shaft extends and a vertical direction and movable to contact with the main body.
2 . The overhead conveying vehicle according to claim 1 , wherein the turning shaft extends in a direction perpendicular or substantially perpendicular to both a traveling direction of the conveyor and the vertical direction, and is located in a central or approximately central region of the main body in the traveling direction of the conveyor, and the pair of dampers sandwich the turning shaft in the traveling direction of the conveyor.
3 . The overhead conveying vehicle according to claim 2 , wherein the base is suspended from the conveyor via a pair of suspensions extending downward in the vertical direction from the conveyor, and the base rotatably supports the suspensions around an axis of the turning shaft that extends in an extending direction of the suspensions.
4 . The overhead conveying vehicle according to claim 3 , wherein
the conveyor includes a traveling driver to be accelerated or braked by a magnetic force generated between the conveyor and a magnetic plate on a traveling rail; and
the pair of suspensions and the pair of dampers do not overlap with each other in plan view as viewed from the vertical direction.
5 . The overhead conveying vehicle according to claim 4 , wherein the damper includes a rubber and a spring.
6 . The overhead conveying vehicle according to claim 5 , wherein the support rotatably supports the turning shaft via a rubber bush.
7 . The overhead conveying vehicle according to claim 4 , wherein the support rotatably supports the turning shaft via a rubber bush.
8 . The overhead conveying vehicle according to claim 3 , wherein the damper includes a rubber and a spring.
9 . The overhead conveying vehicle according to claim 8 , wherein the support rotatably supports the turning shaft via a rubber bush.
10 . The overhead conveying vehicle according to claim 3 , wherein the support rotatably supports the turning shaft via a rubber bush.
11 . The overhead conveying vehicle according to claim 2 , wherein the damper includes a rubber and a spring.
12 . The overhead conveying vehicle according to claim 11 , wherein the support rotatably supports the turning shaft via a rubber bush.
13 . The overhead conveying vehicle according to claim 2 , wherein the support rotatably supports the turning shaft via a rubber bush.
14 . The overhead conveying vehicle according to claim 1 , wherein the damper includes a rubber and a spring.
15 . The overhead conveying vehicle according to claim 14 , wherein the support rotatably supports the turning shaft via a rubber bush.
16 . The overhead conveying vehicle according to claim 1 , wherein the support rotatably supports the turning shaft via a rubber bush.
