An adhesive dispensing device () includes a melt module () including a housing () that defines a receiving space to receive adhesive and a heater () to heat the housing to melt the adhesive, and a control module () releasably connected to the melt module. The control module includes a controller () to automatically recognize a characteristic associated with the melt module and operate the melt module using instructions stored on the controller that correspond to the characteristic of the melt module. A method of operating the adhesive dispensing device is also disclosed.

A hot melt adhesive system includes an adhesive supply for receiving solid or semi-solid hot melt adhesive, and a heater associated with the adhesive supply for melting the solid or semi-solid hot melt adhesive into liquid hot melt adhesive. An adhesive tracking system monitors an output of the liquid hot melt adhesive, and includes a flow meter having a flow inlet and a flow outlet. The flow meter measures an amount of the adhesive flowing out of the flow outlet. A product detector may be used to sense a presence of a product to which the adhesive is applied. A controller then determines the total amount of the liquid adhesive dispensed and the average amount of liquid adhesive dispensed per product.

System and method for monitoring liquid adhesive flow

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.
