Filling liquid and dry chemicals

摘要

Ulano International (V.I.), Inc., Brooklyn, NY, specializes in the manufacture of stencil-making products and chemicals for screen printing, as well as masking films. The company recently installed two new packaging lines to run the chemicals: one line running liquid ink in gallon and quart containers, and the other running sensitizing powder in six bottle sizes ranging from 2 to 15 g. Because of the hygroscopic nature of the powder, it is filled in a climate-controlled room. The powder line incorporates a Model A-410 automatic auger filler from AMS Filling Systems, Inc. (www.amsfilling.com). The A-410 filler features a digital, electronic scale from Mettler-Toledo, Inc. (www.mt.cbm) and Allen Bradley PLC-based controls from Rockwell Automation (www.rockwellautomation.com) that produce netweight accuracies of ± 0.1 to 0.25 percent on fills ranging from less than 1g up to 100 kg. The containers are manually placed on an unscrambling table from which they are shutded automatically through the filler using the included conveyor and indexing package. After filling, the small bottles are collected on an accumulation table from which they are capped and labeled manually.
