Equipment Processes and Labels Syringes After Filling

A de-nester and rod-insertion and labelling machine from Bosch process presterilized syringes downstream of the filling and closing process.

Bosch Packaging Technology’s USD de-nester and RIL rod insertion and labelling machine can be used for downstream processing from the company’s filling and closing machines for presterilized syringes. Syringes filled with liquid pharmaceuticals are either manually or automatically placed on the infeed belt of the de-nester in tubs. Using a gripper, the USD removes the syringes in rows and transfers them to a horizontal, single-lane transport belt. The products remain in a safe and controlled position at all times. Depending on the model, the USD de-nester achieves an output of up to 400 syringes per minute.

In the RIL rod insertion and labelling machine, a transport belt transfers the syringes to a segment wheel, which ensures that the rod is screwed in at optimum conditions. A separate sorting device conveys the rods to a star wheel, which positions the rods and inserts them accurately into the rubber stoppers. The torque control makes sure that the stoppers do not move. In the next step, the segment wheel transfers the syringes to the labelling station, where the labels are applied and checked with a control sensor. A number of additional options are available to read out label data or inspect the quality, readability, and coding of the labels.


To ensure optimum product and operator safety as well as high product quality, the RIL models are equipped with a tip closure control, which checks the presence of the protecting cap on the injection needle. All defective syringes are conveyed to a customer-specific reject station via a star wheel.
