PROBLEM TO BE SOLVED: To provide a conveyance system comprising a vertical conveyance device 20 dedicated for descent, and a horizontal conveyance device 30 connected to the vertical conveyance device and enabling effective utilization of a regenerative electric power.SOLUTION: The electric motors of the vertical conveyance device 20 and the horizontal conveyance device 30 are connected to a DC circuit 50 via inverters 52 and 53, respectively. A power supply device 60 capable of charging and discharging with the DC circuit 50, and a control device 70 for controlling each electric motor are provided. The power supply device 60 is charged by the regenerative electric power of the vertical conveyance device 20, and the horizontal conveyance devices 30, 30... are driven by discharge of the power supply device 60. The vertical conveyance machine 20 is a reciprocating type in which a conveying table 22 on which an article is placed reciprocates vertically, and the conveying table 22 includes an in-machine conveying machine 27, and the in-machine conveying machine 27 is driven by discharge of the power supply device 60.SELECTED DRAWING: Figure 2 【課題】降下専用の垂直搬送機２０とこれに接続される水平搬送機３０とからなり、回生電力を有効に利用できる搬送システムを提供する。【解決手段】垂直搬送機２０及び水平搬送機３０の各電動機が、それぞれインバータ５２、５３を介して直流回路５０に接続されている。直流回路５０との間で充放電可能な電源装置６０と、各電動機を制御する制御装置７０を備えている。垂直搬送機２０の回生電力によって電源装置６０が充電され、電源装置６０の放電によって水平搬送機３０、３０...が駆動される。垂直搬送機２０は、物品を載置する搬送台２２が上下に往復動する往復型であり、搬送台２２は機内搬送機２７を備え、電源装置６０の放電で機内搬送機２７が駆動される。【選択図】図２
