Abstract
A suction device includes a suction hole member including a plurality of suction holes, a suction pump connected to each of the plurality of suction holes, the suction pump configured to suction an air through the plurality of suction holes of the suction hole member to suction a suction target to the suction hole member, and a suction state detector configured to detect a suction state of at least one of the plurality of suction holes corresponding to an end of the suction target suctioned to the suction hole member.
Claims8
A suction device comprising:
- a suction hole member including a plurality of suction holes;
- a suction pump connected to each of the plurality of suction holes, the suction pump configured to suction an air through the plurality of suction holes of the suction hole member to suction a suction target to the suction hole member;
- and
- suction state detectors that each measure airflow through and are disposed within a corresponding one of the plurality of suction holes, and are each configured to detect a suction state of a corresponding suction hole corresponding to an end of the suction target suctioned to the suction hole member
- wherein each of the suction state detectors is an air velocity sensor configured to detect a velocity of the air flowing through the plurality of suction holes.
