摘要:
An adhesive melter and a method for operating the adhesive melter enables predictive maintenance of an exhaust air filter used to remove pressurized air flow that delivers solid adhesive particulate from a fill system into the melter. To this end, the fill system repeatedly actuates to refill a receiving space, and a controller monitors a duration of each fill system cycle. When changes in a calculated average duration of a plurality of fill system cycles exceed a maintenance threshold, an alert is emitted at a user interface to prompt maintenance or replacement of the exhaust air filter before a complete shutdown of the fill system is caused by clogging of the exhaust air filter. Consequently, unplanned downtimes caused by clogged exhaust air filters in the adhesive melter can be minimized, regardless of any variable conditions occurring at the melter.

An adhesive dispensing system is disclosed. The system includes a heater unit configured to heat an adhesive to an application temperature, a fill system configured to supply the adhesive to said heater unit, and a controller. The controller is configured to actuate the fill system to supply the adhesive to the heater unit, operate the heater unit to maintain a unit set point temperature sufficient to heat the adhesive to the application temperature, and operate the heater unit to reduce its temperature from the unit set point temperature following a first set threshold time from actuation of the fill system to supply the adhesive to the heater unit.

An adhesive dispensing system is configured to automatically reduce the temperature of adhesive material to reduce degradation of the adhesive caused by holding the adhesive at an application temperature during periods of low throughput. To this end, a controller of the system operates a heater unit to maintain a unit set point temperature to heat and melt adhesive until a set threshold time has elapsed since the most recent supply of adhesive to the system by a fill system. Once the time elapsed since the most recent supply of adhesive exceeds the set threshold time, the heater unit is reduced in temperature to reduce the temperature of adhesive. This reduction is temperature is large enough to minimize degradation and outgassing but small enough to enable rapid warm-up times after a new supply of adhesive occurs.

The invention relates to a melter, comprising a block (2) having a detachable shell (6), in which there is housed a melting chamber (3) provided with an upper opening that is closed with a hinged and detachable lid (11), the chamber (3) being arranged on lower supports (7), with the freedom to expand upwards, the opening of said chamber (3) incorporating a gasket (8) having an upwardly inclined flexible lip in the outer part on which the shell (6) rests, establishing sealed closure with respect to the chamber (3), whereas on the gasket (8) there is arranged a frame (9) having an upward vertical flange, with respect to which the lid (11) that closes on the gasket (8) is assembled, such that when the chamber (3) expands due to the temperature, the flexible lip allows the expansion maintaining leak-tightness.
摘要:
A method for dispensing epoxy comprising the step of degassing an epoxy. The method further comprises the step of associating the epoxy with an epoxy injector comprising a dispensing end. The method further comprises the step of a computer receiving data representative of a selected container to receive the epoxy. The method further comprises the step of a computer determining a dispensing rate and a dispensing amount, based on the received data. The method further comprises the step of a computer causing the epoxy injector to dispense the determined dispensing amount of epoxy, via the dispensing end, at the determined dispensing rate. The method further comprises the step of a computer causing a dispensing arm, supporting the dispensing end, to retract the dispensing end while the epoxy injector is dispensing the epoxy. The method further comprises the step of curing the dispensed epoxy.
