    • PROBLEM TO BE SOLVED: To provide a workpiece transport device and a workpiece transport system capable of suppressing power consumption as compared with a conventional technique.SOLUTION: A workpiece transport device 10 includes: a workpiece transport unit 20; a motor 27 serving as a power source for moving the workpiece transport unit 20; a stopper abutted by the workpiece transport unit 20, and positioned to a stop position; a brake for turning into an unlock state in which the brake permits the workpiece transport unit 20 to move when power is supplied to the motor 27, and for turning into a lock state in which the brake prohibits the workpiece transport unit 20 from moving at a non-power-supply time at which supply of power to the motor 27 stops; and abutment detection means detecting that the workpiece transport unit 20 abuts on the stopper on the basis of a change in an output torque of the motor 27. If the power is supplied to the motor 27 to move the workpiece transport unit 20, and the abutment detection means detects that the workpiece transport unit 20 abuts on the stopper, the supply of the power to the motor 27 stops.
    • 要解决的问题:提供一种与传统技术相比能够抑制功耗的工件传送装置和工件传送系统。解决方案:工件传送装置10包括:工件传送单元20; 用作移动工件传送单元20的电源的马达27; 由工件传送单元20抵靠并定位在停止位置的止动件; 制动器,用于转向解锁状态,其中制动器允许工件传送单元20在向电动机27供电时移动,并且转向制动器禁止工件传送单元20在一个 向电动机27供电的非供电时间停止; 以及基台检测单元,其基于马达27的输出转矩的变化来检测工件搬运单元20与止动件抵接。如果向马达27提供动力以移动工件运送单元20,并且抵靠 检测装置检测到工件传送单元20靠在止动器上,停止向马达27供电。
