individual components in a tube are successively removed and thenriented for pickup by first positioning the tube , whose ends are opened , in a horizontal orientation such that the components in the tube are upside down . thereafter , a component is at least partially expelled from one end of the tube by directing a stream of gas into the other end of the tube . the component partially expelled from the tube is then withdrawn from the tube to locate the component between a pair of jaws capable of rotation about an arc of 180 °. the jaws then engage the component and thereafter rotate it 180 ° before positioning the component right side up .
