WIPO Patent Application WO/2017/199593
Kind Code:
A1
Abstract:
[Problem] To appropriately deliver an article by suppressing erroneous sensor detection. [Solution] The present invention comprises: a body part 41; a lift platform 42 that has a gripper (holding part) 42a that holds an article FP and that can rise and descend with respect to the body part 41; a lift driving unit 43 that causes the lift platform 42 to rise or descend by feeding out or taking in a flexible belt 43a; a sensor 44 that is provided in the lift driving unit 43 and projects detection waves having directivity to a prescribed position therebelow; a lateral extension mechanism 45 that causes the lift driving unit 43 to protrude laterally from the body part 41 while supporting the lift driving unit 43 in a cantilever manner; and a correction mechanism 46 that corrects a shift in the radiation direction of detection waves that arises from bending of the lateral extension mechanism 45 in a state where the lift driving unit 43 is caused to protrude laterally from the body part 41 by the lateral extension mechanism 45.
