Package transport device and control method

A control method of controlling a package transport device,

• the package transport device including:
• a main body;
• a rail holder held by a rail located above the main body;
• a turntable that is provided between the main body and the rail holder and configured to rotate the main body;
• a first slider portion that extends with respect to the main body;
• and
• a package holder that holds configured to hold a package attached to the first slider portion,
• the control method comprising:
• rotating the main body by the turntable;
• and
• extending the first slider portion with respect to the main body after the turntable rotates the main body, wherein
• the main body includes a frame having a first length in a first direction that is longer than a second length in a second direction, the second direction being orthogonal to the first direction,
• the first slider portion includes the package holder at a first end of the first slider portion, and a counterweight of a predetermined weight at a second end of the first slider portion, the first end being opposite the second end,
• in the rotating, the main body is rotated until a lengthwise direction of the frame is approximately perpendicular to an extending direction of the rail,
• in the extending, the first slider portion is extended from both ends of the frame in the lengthwise direction of the frame so as to maintain balance between a weight of the package and a weight of the counterweight,
• the rail holder includes:
• a first rail holder located on a first side of the frame in the lengthwise direction of the frame;
• a second rail holder located on a second side of the frame in the lengthwise direction of the frame;
• and
• a third rail holder located in a central region of the frame between the first side and the second side in the lengthwise direction of the frame,
• the package transport device further includes:
• a second slider portion that is disposed between the first rail holder and the main body and extends with respect to the main body;
• and
• a third slider portion that is disposed between the second rail holder and the main body and extends with respect to the main body,
• the turntable is disposed between the third rail holder and the main body, and
• in the rotating, the turntable is rotated after the second slider portion and the third slider portion are extended to separate the first rail holder and the second rail holder from the rail.

A package transport device, comprising:

• a main body;
• a rail holder held by a rail located above the main body;
• a turntable that is provided between the main body and the rail holder and configured to rotate the main body;
• a first slider portion that extends with respect to the main body;
• and
• a package holder configured to hold a package attached to the first slider portion, wherein
• the main body includes a frame having a first length in a first direction that is longer than a second length in a second direction, the second direction being orthogonal to the first direction,
• the main body is disposed, by the turntable, at a position in which a lengthwise direction of the frame is approximately perpendicular to an extending direction of the rail, and
• the rail holder includes:
• a first holder held by the rail from above the rail;
• and
• a second holder held by the rail so as to push up on the rail from below.
