by Centrifugal System for Medical Plunger and Barrel

Most barrel and plunger feed systems are relatively simple to tool as the products typically have features that allow the product to hang in gauge rollers quickly and easily. These rollers (sometimes referred to as gravity rollers) consist of counter shafts rotating parallel to each other to allow product to fall in between and hang by the products respective flange or “lip”. The product is then fully oriented and moves quickly to the end of the tracking continuing through the medical manufacturing process. The one caveat to using this type of system is that, even though the tooling is simple, the units are required to be tilted at an angle of 10 or more degrees, to allow the product to move forward at a rapid pace.
This requires that the feed system be elevated to a higher level which could be significant depending on the discharge height required by the customer and how long the rollers need to be for proper orientation and accumulation. The original concept was to utilize this type of system however, we learned that the ceiling height was limited to 8 feet and the original concept exceeded that limited by more than 12″.
The solution was to combine an elevating hopper, where the elevating belt changed from a vertical attitude to a horizontal attitude as soon as it cleared the top of the feeder, with a high speed vibratory inline to move the product quickly into the robot cell of the customer.
The high speed inline was designed with a 2 degree draft instead of the 10 to 15 degrees that would be required with the use of rollers.
This reduced the overall height of the system to 84″ from the 108″+ that was originally designed.
