Article transport facility
A travel path of an article transport facility provided with a plurality of article transport vehicles that travel along the travel path and transport articles, and a control device that controls operation of the article transport vehicles includes a path set in an inspection area for causing a target transport vehicle designated as an inspection target from among the plurality of article transport vehicles to travel along. The target transport vehicle includes a sensor that detects behavior of the target transport vehicle during travel. The control device controls the plurality of article transport vehicles such that only the one target transport vehicle is present in the inspection area, and causes the target transport vehicle to travel in the inspection area in an inspection travel pattern prescribed in advance.
1. An article transport facility comprising:
a plurality of article transport vehicles that travel along a prescribed travel path to transport an article; and
a control device that controls operation of the article transport vehicles,
wherein:
the travel path includes a path set in an inspection area, wherein for causing a target transport vehicle designated as an inspection target from among the plurality of article transport vehicles is caused to travel along the path set in the inspection area,
the target transport vehicle includes a sensor that detects the behavior of the target transport vehicle during travel,
the control device controls the plurality of article transport vehicles such that only the one target transport vehicle is present in the inspection area, and causes the target transport vehicle to travel in the inspection area in an inspection travel pattern prescribed in advance, and
the control device acquires inspection data that is based on a detection result of the sensor from the target transport vehicle during travel in the inspection travel pattern.
2. The article transport facility according to claim 1 , wherein the sensor detects at least one of torque of a motor that causes the target transport vehicle to travel, rotational speed of a wheel of the target transport vehicle or a rotational member that moves in tandem with the wheel, and vibration of the target transport vehicle.
3. The article transport facility according to claim 1 ,
wherein the inspection area includes a straight path, a curved path, a branching part where a path branch into a plurality of paths, and a merging part where a plurality of paths merge together, and
wherein the inspection travel pattern includes acceleration, deceleration, and constant speed travel.
4. The article transport facility according to claim 1 , wherein the inspection area is set to include one of two paths parallelly disposed and on which movement directions of the article transport vehicles are in a same direction.
5. The article transport facility according to claim 1 ,
wherein a weight of the article during transport by the article transport vehicles is taken as a transport weight, and
wherein the control device designates the article transport vehicles as the target transport vehicle based on a condition that the transport weight is a prescribed value.
6. The article transport facility according to claim 1 ,
wherein the target transport vehicle includes a detection result acquisition unit that acquires the inspection data, and an inspection data transmission unit that transmits the inspection data, and
wherein the inspection data transmission unit wirelessly transmits the inspection data to the control device.
