Abstract:
A melting system includes a hopper for receiving solid hot melt material, a heated conduit in communication with the hopper for melting the solid hot melt material, and a valve for allowing solid hot melt material to flow from the hopper to the heated conduit. The valve includes a disk movable between a closed position and an open position, a stem connected to the disk and an actuator for controlling the position of the disk. The disk prevents solid hot melt material from flowing from the hopper to the conduit in the closed position and allows solid hot melt material to flow from the hopper to the conduit in the open position.
Abstract:
A heating system includes an air motor with an exhaust; a pump for a hot melt dispensing system and driven by the air motor; and a shroud enclosing at least a portion of the air motor and the pump to direct heat from the pump to the exhaust of the air motor.
Abstract:
A control module 10 for an electric motor 34 is provided. Such motors 34, including DC brushless motors, are commonly used in many types of equipment including plural component proportioning equipment. The design includes four boards: a power conditioning module 12, a top board 14, a middle board 16 and a bottom board 18.
Abstract:
A melter for a melt system includes a tank, a vibration generating device, and a heater. The tank has a wall for containing a hot melt adhesive, and the vibration generating device vibrates the wall. The heater transfers heat to the tank.
Abstract:
Heating of hot melt adhesive in a hot melt dispensing system is provided by heaters distributed in a plurality of zones of the system. A controller receives input electric power and distributes that electric power to the heaters on a time sharing basis. The controller delivers power to the heaters as a function of the total current target, a temperature set point, the current draw of each of the heaters, and stored priority criteria such as heating priorities of the zones, a history of on and off periods for each heater, and distance from the temperature set point.
Abstract:
A pump system (10) for pumping a fluid includes a motor housing (46), a motor (36), a rod (50), a positive displacement pump (32), a position sensor (52), and a controller (18). The motor (36) is located within the motor housing (46). The rod (50) is connected to and driven by the motor (36) and the positive displacement pump (32) for moving a fluid is driven by the rod (52). The position sensor (52) produces a rod position signal that is a function of a position of the rod, and the controller produces a drive signal for driving the motor (36) as a function of the rod position signal.
Abstract:
A power distribution system for supplying AC power to loads includes an automatic wiring board that realigns voltages and determines a user-supplied wiring configuration. If an acceptable configuration is detected, an auto-wiring relay circuit closes relays to provide appropriate connections from a terminal block to power controllers that control delivery of AC power to loads, such as heating elements. If wiring configuration is incorrect or voltage is outside a safe voltage range, the auto-wiring relay circuit remains open to protect the controllers and loads.
Abstract:
The hydraulic power module 10 consists of 1) a hydraulic manifold 12 to route hydraulic fluid to the correct areas, 2) a hydraulic reservoir 14 that contains hydraulic fluid 16, 3) a hydraulic pump 18, 4) a DC servo motor 20, 5) a directional valve 22, 6) a cooling system 24 7) an integrated filter housing 26 and 8) electronics - motor control 28 for controlling the DC servo motor 20.
