The company offers high-speed plunger rod insertion machines. Syringes are manually fed into an infeed chute, which transfers them to the main transport system. At the heart of the machine is an automated transport starwheel, which moves the product through four different stations, helping assemble up to 60 syringes per minute. Plunger rods are supplied from a vibratory sorting bowl and travel down a feed track to the insertion 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 machine monitors the rotational torque applied to the syringe. The advanced technology allows tightly controlling all process parameters, ensuring consistent product quality, compensating for component imperfections and preventing excessive plunger movement during the process. The z-axis and rotational servo controls allow precise adjustment of the downward feed rate based on the pitch of the thread on the end of the rod tip and the rotary position of the syringe. The machine can handle syringes with a diameter ranging from 16 to 52 mm and heights from 30 to 130 mm, and allows for speeds of up to 60 assemblies per minute.
