To provide a rail switching unit capable of positioning a movable rail member with high precision in a branching part where the course can be switched or distributed to a plurality of rails by the movable rail member, and its rail structure.SOLUTION: At a branch point between a reference rail 1 on which a runner can run and a plurality of branch rails 2, 3, and 4 extending in a plurality of directions from the reference rail 1, a rail switching unit has a movable rail member 15 disposed between the reference rail 1 and the plurality of branch rails 2, 3, and 4, and movable in a direction connecting the reference rail 1 and the plurality of branch rails 2, 3, and 4, a movement mechanism for moving the movable rail member 15 to communicate with a predetermined branch rail, a positioning mechanism for aligning the reference rail 1 and the predetermined branch rail with each other. The positioning mechanism includes a switching unit including an electromagnetic positioning mechanism 22 for holding or positioning the movable rail member 15 in place by applying at least an electromagnetic force.SELECTED DRAWING: Figure 2
【課題】可動レール部材により複数のレールに進路を切換または振り分け可能な分岐部において、可動レール部材を高い精度で位置決め可能なレール切換ユニットと、そのレール構造を提供する。【解決手段】ランナーが走行可能な基準レール1と、この基準レール1から複数の方向に延びる複数の分岐レール2,3,4との分岐部において、前記基準レール1と複数の分岐レール2,3,4との間に配置され、前記基準レール1と複数の分岐レール2,3,4とを結ぶ方向に可動な可動レール部材15と、この可動レール部材15を移動させて所定の分岐レールとを連絡させるための移動機構と、前記基準レール1および所定の分岐レールの位置に合わせるための位置合わせ機構とを備え、前記位置合わせ機構が、少なくとも電磁気的な力を作用させて、前記可動レール部材15を所定の位置に保持または位置決めするための電磁位置合わせ機構22を含む切換ユニットを配置する。【選択図】図2
