FIGURE 7.36 Device for passive orientation of cylindrical
details with slight differences between their ends, a) Examples
of parts having slightly different ends; b) Layout of a device
able to distinguish slightly different ends of the parts; c) Front
view of the device at work; d) Shape of the tray providing
removing of the part when needed.

dimensions of the tray allow only one stable oriented position of the part, namely, that
marked I. The other three possibilities will be extracted from the tray. Positions II and
IV are unstable because of the location of the mass center relative to the edge of the
tray. The part oriented as shown in III falls from the tray when it reaches cutouts 1.
Asymmetrical angle pieces are conveniently oriented by the method presented in Figure
