This is a Bulk Box Loading Station, otherwise known as a BAD, a "Box Alignment Device." It serves a robot that will fill the box with products, in this case 80 lb rubber bales. In the photo to the left, the arms, clamps and other positioning devices are retracted to their home position. When a box is conveyed in, the twin arms swing down to position the box. Then the end clamps close in on it to lock it in place. The box is then pushed to the right side and signals the robot to load it. The conveyor is synchronized because it uses common drive shaft, powered on one side and transfered to the other side by the solid roller in view, a third of the way up the line. The photo to the left shows the empty box captured in place, ready to be filled by the robot.
