Bottle Line Operation Overview
The controller on the conveyor
, within the specified area above, regulates the speeds
of the bottle fill and packing machines. Each machine is connected to a separate
controller that communicates with the conveyor controller. The following ladder
program is for the conveyor controller.
A conveyor feeds filled bottles past a proximity sensor (IN) to a holding area. The
proximity sensor is wired to the I/0 terminal (up count) of the conveyor controller.
The bottles are then sent on another conveyor past a proximity switch (OUT) to the
packing machine. This proximity switch is wired to the I/1 terminal (down count)
on the same controller.
