Patent attributes
In a transfer apparatus, a lifting unit has a lifting mechanism having a plurality of combined members and a motor. The lifting mechanism converts the rotation force of the motor to movement in the lifting direction, transmits the movement to at least one of first and second conveyors, raises or lowers at least one of first and second conveyors, and stops rotation of the motor when one of conveying paths reaches a predetermined height. In that process, a physical limit identification operation is executed in which the motor is rotated to operate the lifting mechanism to a physical operation limit and is then stopped, and control of the motor is changed so that the motor is rotated at low speed until the lifting mechanism reaches the physical operation limit.
