CHAPTER 2 BASIC OPERATION
2. Configuring the Pick-Up Assembly
The construction of the pick-up assembly is changed by the pick-up motor (M1). When the pick-
up motor rotates clockwise, the construction will be made ready for bottom pick-up mode; when the
motor rotates counterclockwise, on the other hand, the assembly will be made ready for top
separation.
When the pick-up motor starts to rotate clockwise, the arm on the pick-up roller shaft transmits its
drive to the original guide and the switching arm. In response, the original guide moves up; the rear
and the front of the separation belt operating in connection with the switching arm move down to
switch the construction of the pick-up assembly for bottom pick-up mode.
When the pick-up motor starts to rotate counterclockwise, the arm on the pick-up roller shaft
transmits its drive to the original guide and the switching arm. In response, the original guide moves
downward. On the other hand, the rear and the front of the separation belt operating in connection
with the switching arm moves upward to change the construction of the pick-up assembly for top
pick-up mode.
