Abstract: A hot melt dispensing system includes a melter, a feed system, a dispenser and a filter. The feed system delivers hot melt pellets to the melter. The dispenser dispenses liquefied hot melt adhesive from the melter. The filter is connected to the feed system and prevents contaminants from passing through the feed system. In one embodiment, the filter comprises a screen filter positioned near a bottom of a pellet hopper. In another embodiment, the filter comprises a series of baffles positioned along the pellet hopper. In yet another embodiment, the filter comprises an electro-static filter coupled to a feed hose.

Abstract: A pumping system comprises a pump, first and second channels, a valve, and an actuator. The pump pumps fluid according to a pumping cycle. The first channel has a first fluid flow orifice with a first diameter, while the second channel has a second fluid flow orifice with a second diameter greater than the first diameter. The valve is configured to direct fluid from the pump to the first channel in a first state, and to the second channel in a second state. The actuator is configured to switch the valve into the first state during a high pressure period of the pumping cycle, and into the second state during a low pressure period of the pumping cycle.

Abstract: Systems and methods for operating a linear pump system involve operating a linear motor system; reciprocating a linear pump and a motor control module that issues commands and a control logic input to the linear motor system. The linear motor system is operated to reciprocate an output shaft between first and second reversal positions. The linear pump is reciprocated with the output shaft to produce a flow of material. A pump reversal command reverses direction of the output shaft. A torque command controls speed of the output shaft. The control logic input reciprocates the output shaft at speeds to produce a constant output condition of the flow of material. The motor control module adjusts the torque command to operate the output shaft at an increased speed above what is necessary for the constant output condition for a temporary time period beginning when the reversal command is issued.
