Abstract:
An automated transport system for use in a material handling system. The automated transport system employs a distributed control system including a top level controller (transport controller), a plurality of second-level controllers (control logic computers) and a plurality of third-level controllers (intelligent drivers). The transport controller (TC) receives material commands from a conventional material control system (MCS). The TC breaks the command into sub-commands directing selected control logic computers (CLCs) to acquire, move to a destination or otherwise interact with a particular container designated by the MCS command. The transport controller selects the CLCs based on the transport system topology, the content of the MCS command and knowledge of which regions of the transport system are controlled by respective CLCs. Each CLC implements the sub-commands by issuing to the intelligent drivers low level control commands to accelerate, elevate, rotate, load or unload the container. Each intelligent driver directly controls one of the electromechanical devices that compose the transport system hardware in accordance with these low level commands. The electromechanical devices can include rail sections (zones), directors, elevators, load port transfer devices and tag readers.

Abstract:
PROBLEM TO BE SOLVED: To relatively easily control lifting of an carried object, while suppressing weight of a whole device. SOLUTION: When a lifting motor 26 rotates a rotational shaft 15, a driving force transmission mechanism 30 transmits a driving force to a lifting body 4 to lift the lifting body 4. The lifting body 4 has a linear slider 18 to carry in/out a cassette 95 between shelves 91. A worm wheel 102 is fixed to the rotational shaft 15. The worm 101 is meshed with the worm wheel 102 to allow a motor 103 for a worm to rotate the worm 101. When lifting the lifting body 4, the motor 103 for a worm rotates the worm 101 according to the rotation of the worm wheel 102. When holding the lifting body 4, the worm 101 and the worm wheel 102 locks themselves to hold the weight of the lifting body 4. COPYRIGHT: (C)2009,JPO&INPIT
