Abstract
Official abstract text for this publication.
A plurality of first vacuum pads for suctioning a workpiece are directly or indirectly attached to a main body. A slider is configured to slide in an outward direction of the main body. When the slider slides to protrude in the outward direction of the main body while the first vacuum pads are suctioning the workpiece, a sensor detects an end portion of the workpiece. While the sensor detects the end portion of the workpiece and the slider is stopped, a second vacuum pad holds up the end portion of the workpiece by suctioning the workpiece at a position outside from positions at which the first vacuum pads suction the workpiece.
First claim
Opening claim text (preview).
1 . A vacuum gripper, comprising: a main body; a plurality of first vacuum pads attached directly or indirectly to the main body and configured to suction a workpiece; a slider configured to slide in an outward direction of the main body; a sensor attached to the slider and configured to detect an end portion of the workpiece when the slider slides to protrude in the outward direction of the main body while the first vacuum pads are suctioning the workpiece; and a second vacuum pad attached to the slider and configured to hold up the end portion of the workpiece by suctioning the workpiece at a position outside from positions at which the first vacuum pads suction the workpiece while the sensor detects the end portion of the workpiece and the slider is stopped. 2 . The vacuum gripper according to claim 1 , further comprising an air nozzle configured to blow air to the end portion of the workpiece while the second vacuum pad is holding up the end portion of the workpiece. 3 . A workpiece sucking and holding method, comprising: suctioning, by a plurality of first vacuum pads attached directly or indirectly to a main body, an uppermost workpiece among a plurality of stacked workpieces; sliding a slider configured to slide in an outward direction of the main body so as to protrude in the outward direction of the main body; stopping the slider when a sensor attached to the slider and configured to detect an end portion of the workpiece detects an end portion of the uppermost workpiece; holding up, by a second vacuum pad attached to the slider, the end portion of the workpiece by suctioning the uppermost workpiece at a position outside from positions at which the first vacuum pads suction the workpiece; and stopping suction of the workpiece by the second vacuum pad and suctioning and holding the uppermost workpiece with the first vacuum pads. 4 . The workpiece sucking and holding method according to claim 3 , further comprising blowing, by an air nozzle, air to the end portion of the workpiece while the second vacuum pad is holding up the end portion of the workpiece.
