o Indexing motion filling and capping machine for injection bottles for production rates up to 200 pieces per minute
o 100 percent in-process weight control (IPC)
o Version for dropper placing
At Interpack 2011, Bosch Packaging Technology presents the new MLF 40x0 for the safe filling and capping of injection bottles in the two to five milliliter format. This new unit, based on the MLF 30x0 series, handles up to 200 pieces per minute and provides exceptionally gentle and safe container transport. High quality is assured through the optimized 100 percent in-process weight control (IPC), for precise tare and gross weighing.
The MLF 40x0 is continuously fed from a turntable, or a transport belt, with the incoming containers individually transferred to the indexing transport system via a servo-controlled segmented star wheel. At the outfeed of the machine, the containers are transferred by another segmented star wheel to a continuous stream and conveyed onto a transport belt or a tray. "The solution of running the infeed and outfeed with a continuous motion, in spite of the indexing working motion of the machine, reduces the risk of a fault. An added additional benefit is that containers can be gently transported out of the machine, separated and trayed - which is a big plus for the safety of the entire line," explained Dieter Bandtel, Product Manager. A further available option is an outfeed with two additional vacuum star wheels for sample removal and rejecting of containers.
The transfer of the containers for the precise tare and gross weighing is especially smooth and safe, thanks to a modern, format specific, adjustable motion sequence. To transfer the containers to the tare and gross weighing station the bottom guide is lowered at a very shallow angle and the container is released approximately five millimeters out of the transport cell. "This achieves highly precise weighing, as it eliminates environmental influences, such as additional environmental loading," explained Dieter Bandtel.
The filling station of the MLF 40x0 is available in a four or eight pitch design, with a horizontal filling needle motion, depending upon the volume of the containers. In addition to the standard rotary valves piston pump system, all current filling systems, such as Time to Peak Filling (TPF) or rolling membrane pumps, are available.
The MLF 40x0 uses "Clean Feed" sorting equipment, for the loading of stoppers and caps into the sorting bowls. Along with low loading heights the laminar flow is less affected and the particle generation is minimized.
When removed from the transport system for crimping, the cap and the containers are rotated simultaneously to achieve a high quality and low particle crimping process. This simultaneous rotation prevents twisting of the container-to-cap seal.
