Bin Drive - Panasonic FP-7818 Service Manual & Parts Manual

2.3 Bin drive

Up and down movement of each bin in the sorter is achieved by the rotation of the
bin motor (M1) located on the lower frame of the sorter. If any overdrive occurs,the
upper and lower limit switches(PI4 and PI5) (micro-switch) detect the abnormality
and protect the machine against damage.
(1) Rolls are fitted to both sides of each bin. The rolls are engaged in the groove of
the reed cam,which firmly secures each bin.
(2) The rotating motion of the bin motor is transmitted to the reed cam (front/rear)
through the bin drive belt. Rolls (for each bin) engaged in the groove in the
reed cam move up and down along the inclination provided in the reed cam,
thereby causing each bin up and down.
(3) The position of the cam is detected by the reed cam home position sensor
(PI2). This is achieved by turning the reed cam home position sensor (PI2) ON
each time the actuator on the reed cam (rear) completes a rotation.
