Abstract:
1. A cassette clamping mechanism, comprising: a frame; a pneumatic cylinder; a reference link pivotally mounted to the frame on a first end of the reference link and pivotally mounted to the pneumatic cylinder on a second end of the reference link so that extension and retraction of the pneumatic cylinder causes the reference link to pivot relative to the frame; an actuator wheel pivotally mounted to the second end of the reference link so that pivoting of the reference link causes rotation of the actuator wheel, wherein the actuator wheel is pivotally mounted to the reference link through a transfer link; and a pair of counter-rotating clamps attached to the actuator wheel; wherein the pneumatic cylinder is pivotally mounted to the frame on a first end of the pneumatic cylinder and to the reference link on a second end of the pneumatic cylinder, such that a clamping function of the pair of counter-rotating clamps occurs by extension of the pneumatic cylinder.
