Bosch expands downstream portfolio for syringes

Bosch Packaging Technology has added new options for the filling and processing of pre-sterilised syringes

Klaus Ullherr, product manager at Bosch Packaging Technology, said: “In downstream processes two steps are required: the rod has to be inserted and the pre-filled syringes have to be inspected.

“The USD de-nester and the RIL rod insertion and labelling machines are ideal additions to our filling and closing machines.”

The syringes are filled with liquid pharmaceuticals and either manually or automatically placed on the infeed belt of the USD de-nester machine in tubs.

Using a gripper, the USD de-nester removes the syringes in rows and transfers them to a horizontal single-lane transport belt.

The transport belt transfers the syringes to a segment wheel which ensures that screwing in of the rod is done in standstill mode.

A separate sorting device conveys the rods to a star wheel which positions the rods and inserts them into the rubber stoppers with the torque control making 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.

The RIL models are equipped with a tip closure control which checks the presence of the protecting cap on the injection needle.

After rod insertion, labelling and inspection the processed syringes can be additionally equipped with a backstopper on the RIL which prevents the plunger head from being pulled out of the syringe and also broadens the finger flange.

Ullherr said: “The downstream equipment is an important part of our line competence for syringes.

“Our specialists have already delivered, installed and put into operation several machines together with our customers.”
