Cleaning apparatus and system including cleaning apparatus
A cleaning apparatus includes: an accommodation unit that accommodates a cleaning cloth; a drawing-out unit that draws out the cleaning cloth; a cleaning clot setting mechanism unit including an ascend/descend member that ascends and descend together with the cleaning cloth drawn out by the drawing-out unit; and a projection unit that upwardly projects as far as a position between an ascended position and a descended position of the ascend/descend member. When the ascend/descend member is located at the ascended position, the cleaning cloth can be drawn out, and when the ascend/descend member is located at the descended position, the projection unit engages the cleaning cloth, and a robot causes an optical device to be pressed against the cleaning cloth engaged by the projection unit, thereby cleaning the optical device.
1. A cleaning apparatus comprising:
an accommodation unit that accommodates a cleaning cloth;
a drawing-out unit that draws out the cleaning cloth from the accommodation unit;
a cleaning cloth setting mechanism unit located between the accommodation unit and the drawing-out unit;
wherein the cleaning cloth setting mechanism unit includes a flat unit,
an ascend/descend member that ascends and descends above the flat unit together with the cleaning cloth drawn out by the drawing-out unit;
a projection unit that projects from the flat unit to a projected position between the ascended position and the descended position of the ascend/descend member; and wherein the ascend/descend member is moved along the length of the projection unit vertically; wherein when the ascend/descend member is in the ascended position, it extends to a top end of the projection unit; wherein when the ascend/descend member is in the descended position, the projection unit extends above the ascend/descend member, wherein the ascend/descend member is located at a base of the projection unit;
a processor configured to:
move the ascend/descend member relative to the flat unit and the projection unit to the ascended position, the cleaning cloth becomes out of engagement with a distal end of the static projection unit,
feed a predetermined amount of the cleaning cloth while the ascend/descend member is being moved to the ascended position,
eject cleaning liquid onto the cleaning cloth when the ascend/descend member is in the ascended position, and
after ejecting the cleaning fluid, move the ascend/descend member relative to the flat unit and the projection unit to the descended position, the projection unit remains in the projected position and engages the cleaning cloth, the cleaning cloth is prevented from moving and cleaning is performed using the cleaning cloth engaged by the projection unit.
2. The cleaning apparatus according to claim 1 , further comprising a cleaning liquid ejection unit that ejects a cleaning liquid onto the cleaning cloth at the cleaning cloth setting mechanism unit when the ascend/descend member is located at the ascended position.
3. A system comprising:
a robot;
an optical device; and
the cleaning apparatus set forth in claim 1 ,
wherein when the ascend/descend member is located at the descended position, the robot causes the optical device to be pressed against the cleaning cloth engaged by the projection unit, thereby cleaning the optical device.
4. The system according to claim 3 , wherein the cleaning apparatus is attached to the robot, and the optical device is located at a fixed position.
5. The system according to claim 3 , wherein the optical device is attached to the robot, and the cleaning apparatus is located at a fixed position.
6. The system according to claim 4 , wherein the cleaning apparatus is attachable to and detachable from the robot.
7. The system according to claim 4 , wherein in accordance with a program of the robot, the optical device is cleaned at each predetermined cycle or when the number of detection errors by the optical device exceeds a predetermined number of times.
