ものであった。■) Prior art and problems In the conventional workpiece suction device of this type, in order to lower the plurality of suction bodies arranged downward from the base and suction the workpieces of various shapes, first, the workpieces and There is a method that has means for detecting the contact of each suction body with a suction pad, and the suction body is lowered by a certain stroke to suction a workpiece of a predetermined thickness. One method is to install a means to detect the contact between the workpiece and the suction pad on the suction body at a representative number of points on the main body, and then stop the descent of the suction body to suction the workpiece. There has been a method in which the main body is provided with means for detecting the complete contact between the workpiece and the suction pad, and the suction main body stops descending to adsorb the workpiece. However, the first method could only pick up a workpiece of a certain thickness, and could not cope with changes in the thickness of the workpiece. Furthermore, the second method cannot flexibly respond to changes in the planar shape of the workpiece, and cannot adsorb small workpieces that fall between several representative points. Furthermore, in the third method, the first and second drawbacks mentioned above can be overcome, but
This method is expensive because it requires as many detection means as there are adsorbents.
