Abstract
A conveyance device has a drive route part wherein conveyance carriages travel at predetermined intervals, which is connected to a storage route part having a drive conveyer chain that supports the conveyance carriages for free travel. The drive route part has a drive conveyer chain including spaced carriage propulsion claw parts. The conveyance carriages have moved pins that horizontally extends in the left/right direction and which are freely detached/re-fitted in the up/down direction with the carriage propulsion claw parts. The conveyance device has a carriage-positioning mechanism which positions a conveyance carriage at a fixed position wherein the moved pin is positioned immediately before a guide ring for a corresponding one of the carriage propulsion claw parts, and has a carriage pushing-out mechanism which pushes out the conveyance carriage positioned at the fixed position, at a timing when the moved pin is fitted to the carriage propulsion claw part.
