Track system, shuttle car system and dispensing system

A track system, comprising:

• a transverse track extending in a first direction;
• a longitudinal descending track disposed at a first end of the transverse track, the longitudinal descending track comprising a first longitudinal descending track segment and a second longitudinal descending track segment disposed at intervals in a second direction, the second direction being arranged to intersect with the first direction;
• an arc-shaped transition segment connecting the first end of the transverse track with the second longitudinal descending track segment;
• and
• a descending track-switching mechanism comprising a descending track-switching segment disposed between the first longitudinal descending track segment and the second longitudinal descending track segment, wherein the descending track-switching segment has its first end rotatably connected to the first longitudinal descending track segment and its second end freely disposed;
• the descending track-switching mechanism has a closed state, in which the second end of the descending track-switching segment engages with the second longitudinal descending track segment to connect the first longitudinal descending track segment with the second longitudinal descending track segment, and an open state, in which the second end of the descending track-switching segment is away from the second longitudinal descending track segment;
• and
• during movement of a shuttle car from the transverse track to the second longitudinal descending track segment via the arc-shaped transition segment, the descending track-switching segment is configured to rotate under the push of the shuttle car to be switched from the closed state to the open state.
