Abstract
A first guide body includes a pair of first guide surfaces and corrects the position in a second direction of a gripping body section relative to a first grip section by at least one of the pair of first guide surfaces coming into contact with the first grip section during a lowering operation for gripping. A second guide body includes a pair of second guide surfaces and corrects the position in the second direction of the gripping body section relative to a target grip section by at least one of the pair of second guide surfaces coming into contact with the target grip section during the lowering operation for gripping. The first guide body and the second guide body are spaced apart from each other in at least either a first direction or the second direction.
Claims7
A transport vehicle configured to travel along a travel route and transport a container having a predetermined shape, the transport vehicle comprising:
- a gripping device configured to grip the container;
- and
- an elevation device configured to raise and lower the gripping device,
- wherein:
- the container comprises:
- a container body;
- and
- a first grip section and a second grip section that protrude upward from a body upper surface, which is an upper surface of the container body, and are configured to be gripped by the gripping device,
- the first grip section and the second grip section extend along a first direction, which is a specified direction parallel with the body upper surface, and are spaced apart from each other in a second direction, which is a direction parallel with the body upper surface and orthogonal to the first direction,
- the gripping device comprises:
- a gripping body section suspended from the elevation device;
- a pair of grippers supported by the gripping body section;
- a grip drive section configured to move the pair of grippers toward each other and away from each other in the second direction;
- a first guide body supported by the gripping body section independent of the pair of grippers, and configured to guide the gripping body section relative to the first grip section;
- and
- a second guide body supported by the gripping body section independent of the pair of grippers, and configured to guide the gripping body section relative to a target grip section, which is either the first grip section or the second grip section,
- the first guide body comprises a pair of first guide surfaces configured to be respectively located on opposite sides of the first grip section in the second direction after completion of a lowering operation for gripping, which is an operation in which the gripping device is lowered by the elevation device in order to grip the first grip section and the second grip section with the pair of grippers,
- the first guide body is further configured to correct a position in the second direction of the gripping body section relative to the first grip section by at least one of the pair of first guide surfaces coming into contact with the first grip section during the lowering operation for gripping,
- the second guide body comprises a pair of second guide surfaces configured to be respectively located on opposite sides of the target grip section in the second direction after completion of the lowering operation for gripping,
- the second guide body is further configured to correct a position in the second direction of the gripping body section relative to the target grip section by at least one of the pair of second guide surfaces coming into contact with the target grip section during the lowering operation for gripping, and
- the first guide body and the second guide body are spaced apart from each other in at least either the first direction or the second direction.
