CONVEYANCE DEVICE, CONVEYANCE SYSTEM, AND HEAD UNIT POSITION ADJUSTING METHOD
First Claim
1. A conveyance device comprising:
- 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 an orthogonal direction 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 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;
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.

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.

12. A method for adjusting a position of a head unit to perform an operation on a conveyed object, the method comprising:
-
detecting a displacement amount representing an amount by which the head unit is moved by an actuator in an orthogonal direction to a conveyance direction in which the conveyed object is conveyed; calculating 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; and adjusting, with the actuator, the position of the head unit based on the detection result and the displacement amount.
