Tire identification using the OPS890 bar code reading system. The system comprises eight CLV490 line scanners arranged to reliably detect the bar code on the tire bead. The reading system is triggered by two WL18 (A) photoelectric reflex sensors that are arranged in an X-shape in the reading zone to reliably detect the tire. Two further WL18 (B) photoelectric reflex sensors arranged one over the other provide fast pre-adjustment of the position of the focus of the code reader.The large depth of field of the devices does not require any further adjustment.
A handling robot fits two sealing rings to injection nozzles. It picks up the injection nozzle from the conveyor belt and places it in the receptacle on the assembly table (process not shown here). A WT12L laser photoelectric proximity sensor monitors for presence in the receptacle and the exact positioning of the nozzles. The rings are supplied on two vibration conveyors. WF fork sensors mounted at the outlet on the conveyors control the vibration conveyors such that rings are always available. IQ05 inductive proximity sensors check the presence of rings in the two pick-up stations. The handling robot collects a ring using end effectors attached to its pivoting arm and fits it to the nozzle. The end effectors are actuated using pneumatic cylinders. MZT6 magnetic cylinder sensors poll the position of the piston in the cylinder. Once both rings are fitted, the robot replaces the nozzle on the conveyor belt where an ICR840 code reader reads the two-dimensional code applied by laser (direct part marking) and transmits the information to a central computer for quality assurance.
