Bausch Advanced Technology Group is proud to introduce its latest development in filling and closing technology – the fully automatic Class I, Div. I explosion proof Type 561. The model has been developed for an American customer and was successfully FATed and delivered at the end of February.
The linear style 561 machine is able to process 4 liter (1 gallon) bottles with a speed of up to 40 pc/hour.
The bottles are manually fed onto the main transport belt, which is made of a non-shedding plastic with separation guides to avoid bottle-to-bottle contact.
Based on the special requirements of BATGs customer, the machine features an explosion proof design and processes two different bottle styles – a pre-sealed 1 gallon glass bottle and a pre-sealed 4 liter plastic bottle – which require a different approach in the closing process.
Upon arrival at the filling station, the cap of the glass bottles are unscrewed and taken off by a cleanroom robot arm. Using a gripper tool, the arm will reuse the cap to seal the next bottle on the transport belt, which has already been filled. For processing the plastic bottles the cleanroom robot is required to remove the cap and discard it into a disposal bin. After the container has been filled, the robot takes the final closure out of the supply track and screws it onto the plastic bottle.
Equipped with an IPC-system (In-Process-Control), the machine’s filling process takes place on a weigh scale, which weighs the bottles before and after filling. Bottles whose pre-weight is out of tolerance will be marked as rejects.
Unlike BATG’s standard filling machines, which usually feature a filling system based on rotary piston or peristaltic pumps, this machine’s filling system is based on diaphragm valves.
After the bottles have been filled and closed, they are transferred to the servo-controlled labeling machine Type 604, where self-adhesive, re-printed labels are applied to the containers by a smoothing roller. The containers are checked by a label application check sensor as well as a code reader (checking for batch information on the label print), before they are discharged.
