Abstract
A bulk adhesive transfer system for transferring adhesive particulate to a melter includes a bulk supply and a transfer device, which may define a hopper of the melter, a mobile bin, and/or a buffer unit. The transfer device is configured to receive unmelted adhesive particulate from the bulk supply and then be selectively docked with the melter to transfer the adhesive particulate to the melter. The bulk adhesive transfer system may also include a knife gate valve device, which includes a plurality of ports that sequentially open and close to control flow of the adhesive particulate towards the melter. The bulk adhesive transfer system simplifies refilling operations for a melter while enabling continuous operation of the melter, even when the transfer device is undocked for removal from the melter.
