Filed: 1981-12-11
Abstract: PURPOSE:To enable a single dip container to cover trimming process of a panel coat in the multiple type mixing production by positioning and holding a panel vertically based on the position of a panel pin that is projected on the inner surface at the opening side of the panel. CONSTITUTION:Panels P1 to P3 with various size are held by panel chucks 1, based on the center of a panel pin PP that is protruded on the inner surface of the edge at the opening side and are trimmed by the panel pin standard method by which the distance D3 between the panel pin PP and the reference level of the panel chuck 1 is held constant.

Abstract: PURPOSE:To supply parts to an objective place with high accuracy by providing the tip end of a supply rod with a projecting piece which holds the parts from down-below, and thereby letting suction magnetic force become extinct roughly at the same time with the suspension of the advance of the supply rod. CONSTITUTION:A supply rod 8 advances close to an objective member 12 while the head 7 of a bolt 5 is still sucked onto the tip end surface of the supply rod 8 so as to be suspended thereafter. In this case, the tip end of the bolt 5 is positioned very close to a hole 13. Then, an inner rod 10 is retreated, a magnet 11 is separated from the head 7, suction magnetic force against the bolt 5 is made to become extinct, and then, the whole of the bolt 5 is rotated so as to be raised up while the head 7 is being supported by the inner face of the projecting piece 9 of the supply rod 8. This constitution allows the locus of the behavior of the bolt 5 to be identical at all times, thereby letting the bolt 5 be coupled in the hole 13 with high accuracy.
