The Type 515 features an automated transport starwheel, which moves
product through four different stations, helping assemble up to 30 syringes per
minute. At the first station, a pneumatically-actuated gripper assembly picks
up a plunger rod from the end of the vibratory track and leverages a 2-axis
robotic arm to thread it into a syringe. At the second station, backstops are
carefully placed on the flange of each syringe. The third and fourth station
check for plunger rod and backstop presence. The key differentiator of the
machine is its ability to monitor the rotational torque applied to the syringe. When the plunger and the rod are
fully assembled, the servomotor spinning the disk detects an increase in torque
and stops both the rotational and z-axis motors simultaneously. In the event
the torque limiting value is not reached, the process aborts. This potentially
defective part is tagged and automatically discharged to the reject station.
