Title:
Air type solid material transfer pump
Document Type and Number:
Japanese Patent JP6253249
Kind Code:
B2
Abstract:
A transfer pump (14) for moving pellets of adhesive includes a pump housing (32) with an adhesive inlet (34) coupled to a supply hopper (12), an adhesive outlet (36) coupled to an outlet hose (42), and an adhesive passage (38) extending between the adhesive inlet (34) and the adhesive outlet (36). A first air nozzle (48) communicates with the adhesive passage (38) adjacent the adhesive inlet (34) and expels a first air jet that pushes pellets of adhesive through the adhesive passage (38) . A second air nozzle (50) communicates with the adhesive passage (38) between the adhesive inlet (34) and the adhesive outlet (36) and expels a plurality of second air jets that draw pellets of adhesive through the adhesive passage (38) by a vacuum force. The first and second air nozzles (48, 50) prevent clogging of pellets in the adhesive passage and enable movement of larger pellets than either air nozzle individually.
