Abstract
A transport facility includes at least one transport vehicle, a guide rail, and a control system, and the at least one transport vehicle includes a guide section that is guided by the guide rail. The control system, when controlling the at least one transport vehicle traveling on the first branch route to perform return travel for entering the second branch route after reversing, executes branch return control for (i) controlling the guide drive section to move the guide section located at a first position to a second position side while the at least one transport vehicle is reversing on the first branch route, and (ii) controlling at least one transport vehicle to move forward on condition that the guide section has moved to the second position.
Claims8
A transport facility comprising:
- at least one transport vehicle configured to travel along a travel route;
- a guide rail provided along the travel route;
- and
- a control system configured to control the at least one transport vehicle, and
- wherein:
- a direction along the travel route is defined as a travel direction, and a direction orthogonal to the travel direction as viewed vertically is defined as a width direction,
- the at least one transport vehicle comprises:
- a guide section configured to be guided by the guide rail by contacting the guide rail from one side in the width direction;
- and
- a guide drive section configured to move the guide section in the width direction,
- the travel route comprises a branch portion branching from a single route into a first branch route and a second branch route,
- the guide rail is provided in the branch portion and not being provided in a branch upstream segment upstream of the branch portion,
- the at least one transport vehicle is configured to perform forward movement for traveling along the travel route in a forward direction and reverse movement for traveling along the travel route in a reverse direction to the forward direction, and
- when a position of the guide section in the width direction for entering the first branch route is defined as a first position, and a position of the guide section in the width direction for entering the second branch route is defined as a second position, the control system, when controlling the at least one transport vehicle traveling on the first branch route to perform return travel for entering the second branch route after reversing, executes branch return control for (i) controlling the guide drive section to move the guide section located at the first position to the second position side while the at least one transport vehicle is reversing on the first branch route, and (ii) controlling the at least one transport vehicle to move forward on condition that the guide section has moved to the second position.
