The conveyor can operate in three different modes, one of the modes is called Counting Conveyor. This mode uses the switch located at the drop-off area of the main machine to count the pouches. While in this mode, the conveyor will attempt to group the pouches as they come off the machine. The conveyor will stop when the photo-eye does not detect a pouch in the set time to help maintain groups. When set count equals actual count, the conveyor will index at set speed for set duration.

Active Count displays the current count total and has a reset pushbutton.

Pouch Count is the input for the desired number of pouches to group.

Base Speed is the speed in Hz at which the conveyor will run while counting.

Index Speed is the speed in Hz at which the conveyor will run at high speed to separate pouches.

Index Duration is the amount of time the conveyor will run at index speed to separate the pouches from the following group.

No Pouch Stop Delay is the time to stop conveyor when photo-eye does not detect pouch.

The Diverting Conveyor, which does not use the prox switch switch. This mode uses the small light curtain sensor at the end of the conveyor.

While in this mode, the pouches coming off the machine are counted by the light curtain sensor at the end of the conveyor. Once accumulated count equals set count. The diverter will divert either left or right.

On the HMI an operator has four input parameters for adjustments.

The top display/input is the pouch count; this is the number of pouches that is required before the diverter shifts positions. Active Count is the number of pouches the light curtain has seen. When the active count equals the pouch count, the diverter will shift. The active count can be reset with the reset pushbutton on this screen.

Base Speed in Hz is the speed of the conveyor; this adjusts spacing between pouches.

Pouch Delay is the time to delay the divert chute function for the last pouch in count, fall time.

The last mode is Manual Conveyor. When in this mode Base Speed sets the conveyor speed, this mode does no counting of any type.
