Claims

[Scope of utility model registration request]

an input shaft rotatably supported in the housing;
An endless first grooved cam and a second groove are fixed to the input shaft and have a tapered rib forming a predetermined geometrical curve on the outer circumferential surface, and each has a predetermined geometrical curve on both end surfaces. a roller gear cam having a cam; a first output shaft disposed to intersect the input shaft at right angles and supported by the housing so as to be rotatable in forward and reverse directions and slidable in the axial direction;
A follower turret is coaxially spline-fitted to the outer peripheral side of the first output shaft to allow movement of the first output shaft in the axial direction, and is rotatably supported by the housing. a cam follower provided on the outer peripheral surface of the follower turret and engaged with the tapered rib of the roller gear cam, a fulcrum part rotatably supported by the housing, and a force point part connected to the first groove cam of the roller gear cam. a first swinging arm that is engaged and whose point of action is engaged with a groove formed on the outer circumferential side of the first output shaft, and a housing that is disposed parallel to the input shaft and is rotatable. It includes a second output shaft that is pivotally supported, and a second swing arm that has one end fixed to the second output shaft and the other end engaged with the second groove cam of the roller gear cam. A cam-type pick-and-place device.
