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.

Conveyance device using carriage

A cart-type transporting device includes left and right auxiliary rotating bodies moving in conjunction with left and right turning-section toothed wheels that guide a first endless chain; and a turning pathway section that protrudes at a position between the auxiliary rotating bodies, and that is provided with a lower protruding cam over which a transporting cart can pass. Left and right front-side projection shafts of the transporting cart engage with an engagement section of the respective auxiliary rotating bodies. Left and right rear-side projection shafts engage with an engagement section of the first endless chain. When the projection shafts are picked up by the rotation of the turning-section toothed wheels and the auxiliary rotating bodies, the lower protruding cam supports and guides a cam-following roller at a bottom section of the transporting cart in accordance with the same rotating pathway as the engagement section.

Cart-type transporting device

A cart-type transporting device has a first endless chain and a second endless chain that move in conjunction with and parallel to one another in a lifting/lowering pathway section, and the first and second endless chains have engaging parts. A transporting cart has engaged parts that engage with the engaging parts of the first endless chain in a horizontal pathway section In the first endless chain, the engaging parts are provided at regular intervals, and the engaging parts of the first endless chain and the engaged parts of the transporting cart are detachably fitted together such that the transporting cart can be attached/detached in the vertical direction in the horizontal pathway section.

A slat conveyor has a plurality of slat bodies supported between a pair of left and right driving endless turning bodies by concentric horizontal support shafts and has a pair of front and rear guide rollers supported to a guide rail laid on each of upper and lower horizontal path sections. A U-turn guiding mechanism at both ends includes the guide rollers, a slat body posture controlling rotating body, and a drive mechanism for the rotating body. The rotating body has the same turning radius as that of the horizontal support shaft on a U-turn path section, and includes an engaging portion for positioning and turning the guide rollers. The drive mechanism drives the rotating body such that the engaging portion is turned in the same direction and at the same speed as the turning speed of the horizontal support shaft on the U-turn path section.

Slat conveyor

A carriage guiding post in a transfer lifter, is a four-sided support post of an approximately square shape in cross section the support post having carriage guiding rail recesses provided in three of the four sides thereof, and a counter weight guiding rail track provided on the remaining side of the support post, the carriage guiding rail recesses and the counter weight guiding rail all extend continuously throughout the length of the support post, wherein the counter weight guiding rail track is a rib projecting from a central region of the side of the support post and extends lengthwise thereof, the rib having an approximately isosceles triangle shaped cross section.
