Abstract
A conveyance device includes a conveyor to convey a conveyed object in a conveyance direction, a head unit to perform an operation on the conveyed object, an actuator to move the head unit in a direction orthogonal to the conveyance direction, an actuator controller to control the actuator, a displacement sensor to detect a displacement amount representing an amount by which the head unit is moved by the actuator, and a controller. The controller is configured to calculate a detection result including at least one of a position of the conveyed object in the orthogonal direction, a speed of travel of the conveyed object, and a travel amount of the conveyed object. The controller is configured to calculate a command value based on the detection result and the displacement amount output from the displacement sensor, and output the command value to the actuator controller.
