Title:
UNMANNED TRANSPORTATION DEVICE
Document Type and Number:
Japanese Patent JP2019133404
Kind Code:
A
Abstract:
To provide an unmanned transportation device capable of improving safety while suppressing an increase in cost by allowing for detection of an obstacle using a detection unit of a self-propelled carrier in a state in which a detection region of a detection unit provided in the self-propelled carrier is restricted by a carrier truck.SOLUTION: An unmanned transportation device comprises a carrier truck 30, and a self-propelled carrier 10 attachably and detachably connected to the carrier trunk 30. The self-propelled carrier 10 comprises a detection part 20 which forms a detection region AR1 detecting an obstacle. The carrier truck 30 comprises a detection restriction part which forms a detection restriction region in which obstacle detection is restricted in a part of the detection region AR1 in a state in which the carrier truck is connected to the self-propelled carrier 10, and a movable part 40 which changes from a non-detection posture P1, which is a posture not detected by the detection unit 20, to a detection posture, which is a posture detected by the detection unit 20 as an obstacle when abutting on an obstacle existing in the detection restriction region.SELECTED DRAWING: Figure 1
