The Maxim RX-9s is a staging feeder. When the feeder stages a piece of product to the photocell, something else must remove the piece from the feeder such as an insert gripper jaw (shown below), vacuum cup arm, robotic arm, or nip wheel. The photocell is position to stage the leading edge of each piece of product. When the photocell is blocked, the motor will stop. When the photo- cell is unblocked, the motor will start.
The RX-9s can also act as a continuous feeder. If the photocell is pointed away and not blocked, the feeder will run continuously. This operating mode is typically used inline with flat belt or vacuum conveyors for inkjet printing, labeling, tabbing, laminating, and virtually all other continuous feeding applications.
