A packaging company was looking to convey the plastic handle grips commonly found on plastic buckets (see below pic for reference). The grips are roughly 3″ long and about a 1/2″ in diameter and they currently have an operator manually load the hopper on their vibratory feeder which is located on the 2nd floor, about 12′ away from the receiving area. The hopper is level controlled and the machine uses 3 grips per minute so as the level dropped, the operator would have to stop the process, go down and load the parts in a box, then go back up the stairs and dump the box into the hopper. This was a very tedious process, which wasted a lot of time so they reached out to EXAIR for a more effective way to get the job done.
After further discussion, I recommended our 1-1/4″ Line Vac Kit for the application as this unit has a 1″ inside throat diameter that would easily pass 1/2″ diameter parts and deliver them to the overhead hopper. Since they were only needing to load a few parts at a time, I proposed they have the operator simply feed the parts in to the Line Vac suction line to avoid any potential blockages. Additionally, I suggested they incorporate our Model# 9040 foot valve into the process to simplify the operation and provide additional control so they are only using their compressed air supply when needed to move the parts. The foot pedal will allow the operator to activate the Line Vac each time they feed parts moving in to the hopper. Among the items this kit includes is a pressure regulator which would allow them to adjust the supply pressure to the unit, providing control over the conveyance rate and velocity at which the parts are ejected.
EXAIR’s Line Vac Air Operated Conveyors are able to convey light materials, like plastic pellets, to more abrasive materials like steel shot blasting media. To see how a Line Vac might fit into your process or for help selecting the best EXAIR product for your needs, give me a call, I’d be glad to help.
