Section 7: Cassette Handling / Plate Handling
Function
The function of Cassette Handling is to move the CASSETTE into position in the CR 800 so that the PLATE can be extracted for scanning. Plate Handling involves
unlatching the PLATE and hooking it onto the EXTRACTION BAR. After the scan is completed the PLATE is reinserted into the CASSETTE and the CASSETTE is
transported to the CASSETTE LOADING STATION so that it can be removed by the Operator.
SLED PLATE
Several switches, motors, sensors and other components are mounted to the top of the SLED PLATE. When the SLED PLATE moves
forward and rearward in response to the indexing of the DUPLEX CAM, these components initiate various Cassette handling funcitons. A
number of CAM FOLLOWERS, attached to the underside of the SLED PLATE engage stationary components on the INTERMEDIATE
PLATE to actuate the various operations of Cassette Handling.
INTERMEDIATE PLATE
The INTERMEDIATE PLATE, is a stationary plate, mounted beneath the SLED PLATE. Several components, mounted on the top surface
of the INTERMEDIATE PLATE provide the position and direction for the movements of the components on theSLED PLATE as it moves
forward and backward during the CASSETTE loading and unloading operations.
