Title:
VERTICAL BRANCH DEVICE FOR SELF-PROPELLED CARRIAGE
Document Type and Number:
WIPO Patent Application WO/2008/012891
Kind Code:
A1
Abstract:
A branch device for causing a self-propelled carriage (10) to switch over between
a horizontal rail (50) and a vertical rail (30, 30') that are arranged in
a crossing manner. The self-propelled carriage has, coaxially arranged on its
left and right sides, pinion gears (21) for drive wheels, horizontal travel wheels
(22, 23) arranged on both sides, in the forward-backward direction, of each pinion
gear, vertical travel wheels (24, 25) arranged on both sides, in the vertical
direction, of each pinion gear, and a drive mechanism for the pinion gears. A crossover
point between the horizontal rail and the vertical rail having a rack (36) surface
that meshes with the pinion gears and also having travel surfaces (33, 34) for
allowing the vertical wheels to roll on them is divided. In the divided section
are provided a curved rail section (70) and a linear rail section (90). In the curved
rail section (70), a rack (76) surface and travel surfaces (73, 74) are formed
in a substantially L-shaped curve in a side view and a horizontal section of the
curve is connected to the vertical rail. In the linear rail section (90), the rack
(96) surface and travel surfaces (93, 94) are linearly formed and are connected
to the vertical rail. The curved rail section and linear rail section of a branch
rail section are selectively connected to the divided rail.
