    Abstract: Systems and methods for controlling adhesive application are disclosed. The systems and methods may include a controller and one or more sensors configured to measure an amount of adhesive applied to a plurality of substrates by a pump, detect a number of the substrates, determine an amount of adhesive applied per substrate, compare the adhesive applied per substrate to a target value, and adjust a pressure of the pump based on the comparison. The sensor(s) may include one or more of a valve sensor coupled to an adhesive supply, a flow rate sensor coupled to a manifold, a flow rate sensor coupled to one or more hoses, and a flow rate sensors coupled to a gun.

    Abstract: Systems and methods for tuning a closed-loop controller for a hot melt liquid dispensing system are disclosed. In an example method, based on a set temperature setpoint, the hot melt liquid dispensing system is maintained at a steady state with respect to a temperature process variable and a heater duty cycle control variable. The heater duty cycle control variable is brought to a sustained oscillation. An amplitude and an ultimate period are determined. An ultimate gain is determining based on the step value and the amplitude. A proportional, integral, or derivative constant is determined based the ultimate period and/or ultimate gain. The closed-loop controller is implemented using the proportional, integral, or derivative constant.

    Abstract: In one example, a melter has a housing, a heater, a vent, and a filter medium. The housing defines a receiving space that supports adhesive therein. The heater heats the receiving space of the housing to melt the adhesive. The melter defines an adhesive inlet therein that receives adhesive carried by a transport supply gas into the receiving space. The vent extends through a wall of the melter and permits the transport supply gas to escape from the melter. The filter medium is supported in the vent to capture particulates from the transport supply gas escaping the receiving space, and is positioned relative to the receiving space such that heat from the receiving space causes the particulates captured by the filter medium to melt and fall into the receiving space.

    Abstract: Systems and methods for air pressure control in a hot melt liquid dispensing system are described. An example hot melt liquid dispensing system includes a pump that pumps hot melt liquid to an applicator. The hot melt liquid dispensing system also includes an air flow path that supplies pressurized air to the pump and an electronic pressure sensor associated with the air flow path. The hot melt liquid dispensing system also includes a controller that receives an electronic signal from the electronic pressure sensor indicative of an air pressure in the air flow path and causes adjustment to the air pressure in the air flow path based on the electronic signal from the electronic pressure sensor.
