Picking device

A picking device comprising:

• a rail that extends over a first area and a second area;
• a first transfer device that transports an object from the first area to the second area by picking up the object in the first area, traveling along the rail, and then releasing the object in the second area, the first transfer device including a first traveling body that travels while being guided by the rail, a first arm that includes a proximal end portion attached to the first traveling body, and a first holding device that is attached to a distal end portion of the first arm to hold an object;
• a second transfer device that transports an object from the first area to the second area by picking up the object in the first area, traveling along the rail, and then releasing the object in the second area, the second transfer device including a second traveling body that travels while being guided by the rail, a second arm that includes a proximal end portion attached to the second traveling body, and a second holding device that is attached to a distal end portion of the second arm to hold an object;
• and
• a transfer control device that controls the first transfer device and the second transfer device to cause the first transfer device and the second transfer device to pick up objects in parallel in the first area, travel in parallel along the rail, and then release the objects in parallel in the second area.
