Abstract
A rail guided vehicle system includes a rail that includes a first main rail, a second main rail, and a connection rail, and vehicles. Each vehicle includes a diverging roller supporting member that supports a pair of first and second diverging rollers such that the first and second diverging rollers shift, and a position stabilizing roller supporting member that supports position stabilizing rollers such that the position stabilizing rollers do not shift. The rail includes a first diverging guide configured to guide the first diverging roller, a second diverging guide configured to guide the second diverging roller, and a position stabilizing roller guide configured to guide the position stabilizing rollers in the no-guide zone where the diverging guide is absent.

A rail guided vehicle system comprising:
- a rail that includes a first main rail, a second main rail, and a connection rail that connects the first main rail to the second main rail;
- and
- vehicles that travel while being supported and guided by the rail;
- each of the vehicles including:
- a travelling unit configured to travel on the rail;
- a first diverging roller and a second diverging roller that are arranged with a gap in between the first diverging roller and the second diverging roller in a width direction of the travelling unit;
- a diverging roller supporting member arranged in the travelling unit, the diverging roller supporting member supporting the first diverging roller and the second diverging roller such that the first diverging roller and the second diverging roller shift in the width direction of the travelling unit;
- position stabilizing rollers configured to stabilize a travelling position of the travelling unit;
- and
- a position stabilizing roller supporting member that is arranged in the travelling unit, the position stabilizing roller supporting member supporting the position stabilizing rollers such that the position stabilizing rollers do not shift in the width direction of the travelling unit;
- and
- the rail includes:
- a first diverging guide that extends, on one side of the connection rail in a width direction of the connection rail, from the first main rail along an extending direction of the connection rail, the first diverging guide being configured to guide the first diverging roller;
- a second diverging guide that extends, on another side of the connection rail in the width direction of the connection rail, to the second main rail along the extending direction of the connection rail while having a no-guide zone that does not overlap with the first diverging guide in the extending direction of the connection rail, the second diverging guide being configured to guide the second diverging roller;
- and
- a position stabilizing roller guide that is arranged in the no-guide zone, the position stabilizing roller guide being configured to guide the position stabilizing rollers in the no-guide zone.
