The machine is equipped with highly sensitive control systems, ensures reliable capping and achieves an output of 120 containers per minute.
The VRT 1010|1020 can also be combined with barrier and containment systems. “Meeting the latest technical production standards, it is also suitable to handle toxic products,” said Dieter Bandtel, product manager at Bosch Packaging Technology. The machine meets the current EU GMP-requirements (Good Manufacturing Practice) according to Annex 1.
Reliable quality control via sensor
Depending on the version, the intermittent VRT 1010|1020 takes over the filled and plugged injection and infusion vials from an upstream filling machine or a rotary table via single or double lane. The vials pass through all working stations in a conveying starwheel with counter guidance. Before capping, a camera-based sensor performs the stopper presence check. Containers with a missing or an incorrectly placed stopper are guided to an outward station, correctly stoppered containers continue to the capping station.
The caps are attached loosely via a tow-off chute after being picked up from the conveying system. While the containers are rotated, they are clamped via a plunger and tilted against a freely revolving roller by means of a servo-controlled tilting movement. “The combination of releasing the containers from the transport system and the freely rotating capping roller ensures an especially low-particle process,” Dieter Bandtel explained. The exact repeatability of the rotation speed allows a complete validation of the process.
Fast, safe and efficient
Thanks to the rotary concept, further control systems can be added to the VRT 1010|1020. The sealing machine is equipped with a camera for best capping quality. It checks whether the capping process has taken place and the caps have been optimally crimped. “To achieve reliable results, we use mirrors which enable an all-round view for the camera to identify incorrect objects,” described Dieter Bandtel. The containers which do not meet the requirements are conveyed into an additional reject station. Correctly closed injection and infusion vials are transported to a traying-off station or onto a discharge belt. A modern touch-screen allows for easy handling and enables the storage and full reproducibility of format specific settings.
