Today I worked with a long standing customer that was interested in using the Line Vac technology to provide a method for part rejection. The parts come out of a bin and travel to the next station for final assembly. There is an accept/reject analysis system along the way, and it was decided that the Line Vac would offer an easy way to remove the part from the conveyor and transport it to a reject bin.
The parts are very small, with 0.093″ to 0.187″ OD and 0.178″ to 0.335″ lengths. Part weights were 0.27 grams or less, so a very small and light weight item. Maximum part processing was estimated at less than 6 parts per minute, so low speed and low transfer rates apply. The final piece of information was the distance for conveyance, and here it was only a few inches up and then 4′ over to the reject bin.
Based on all the information about the parts, the process and the transfer distance, it was determined that the 3/4″ Light Duty Line Vac would be an ideal choice for the application. The unit is available as part of the model 132075 Light Duty Line Vac Kit, which includes a Automatic Drain Filter Separator and a Pressure Regulator. The Pressure Regulator is especially important in this application, as it will allow for pressure adjustment to provide the best performance while keeping the compressed air usage to a minimum.
EXAIR manufactures 3 styles of Line Vac- Light Duty, Standard, and Heavy Duty with either smooth bore hose or NPT threaded ends. They are offered in 4 types of materials- Aluminum, Type 303 and Type 316 Stainless Steel, and a hardened alloy construction. An important factor in material selection is the abrasiveness of the material to be conveyed.
