METHOD FOR CONTROLLING CONVEYING DEVICE WITH POWER ASSIST, AND CONVEYING DEVICE WITH POWER ASSIST

摘要

PPROBLEM TO BE SOLVED: To provide a control technology of a conveying device to feed the assist power during the movement by an electric motor in which the conveying device with the power assist in a stopped state is easily moved, and the operability of the conveying device is enhanced. PSOLUTION: In the conveying device with the power assist having a driving unit provided with drive wheels driven by an electric motor and provided in a contact/separating manner to/from a traveling surface while the traveling assist power is given by the drive wheels, the drive wheels are separated from the traveling surface as the power supply of the conveying device is turned OFF. The power supply of the conveying device is turned OFF when a power supply switch is turned off, or when the stopped state is elapsed over a predetermined time. The drive wheels are moved in the separating direction from the traveling surface after the power supply switch is turned off, or after the stopped state of the conveying device is elapsed over the predetermined time and before the power supply is automatically turned OFF. The conveying device is stopped when the power supply is turned OFF and the drive wheels are not brought into contact with the traveling surface. The friction of the electric motor and the drive wheels do not form any load during the manual traveling, and the operability of the conveying device is enhanced thereby. PCOPYRIGHT: (C)2006,JPO&NCIPI
