摘要： A method is provided for dispensing materials (20) with fluctuating viscosity over time, such as liquid adhesives. Using a control algorithm derived from viscosity data or lab testing results, a first pressure or mechanical drive speed is used to force viscous material (20) from a supply syringe (14) during a first dispensing cycle. After a certain amount of time, a correction model is applied to the control algorithm to increase the pressure or drive speed as viscosity of the material (20) increases. A second higher pressure or drive speed is then used to force viscous material (20) from the supply syringe (14) during a second dispensing cycle. The correction model can be based on empirical data about the viscous material (20), or a camera system (30) can be used to periodically adjust the pressure or drive speed as required to maintain a substantially uniform dispensing rate.

摘要： A heated air manifold of reduced physical dimensions for heating process air for use in dispensing heated liquids, such as hot melt adhesives. The heated air manifold includes at least one heating element and an air plenum having an air inlet and an air outlet. The dimensions of the air plenum are optimized for providing a compact heated air manifold for use in various adhesive dispensing systems, such as systems assembled from modular adhesive manifold segments, while retaining the ability to heat the process air in the air plenum to a desired application temperature. The heated air manifold may include a thick film flat heater disposed in the air plenum. The air plenum may have multiple individual segments winding throughout the volume of the heated air manifold.

摘要： Liquid dispensing module and methods for dispensing a heated liquid onto a substrate. The dispensing module includes a dispenser body receiving liquid from a heated liquid distribution manifold and an actuator having a housing with an air piston movable in an air cavity and a solenoid valve for pressurizing the air cavity. Movement of the air piston controls a flow-regulating mechanism for selectively dispensing liquid from the dispenser body. A thermally insulating shield may be provided for reducing heat transfer from the manifold and/or dispenser body to the actuator so that the solenoid valve can be mounted directly to the housing and the effective volume of the air cavity can be reduced. The cycle time of the liquid dispensing module may be specified by selecting an initial volume of the air cavity and an effective valve flow coefficient for the actuator that characterizes the air flow to the air cavity.

摘要： An apparatus for controlling a speed of a motor of a metering pump providing pressurized fluid at a dispensing gun. The dispensing gun is opened and closed to dispense fluid onto a substrate being carried by a conveyor past the dispensing gun. The apparatus has a pressure control producing first motor speed signals as a function of changing speeds of the conveyor and changing fluid pressures in the dispensing gun when the dispensing gun is open. A flow control produces second motor speed signals as a function of the changing speeds of the conveyor. During changes in conveyor velocity, a motor speed control provides the first motor speed signal to the pump motor which operates the motor at speeds causing the pump to provide fluid to the dispensing gun at pressures changing at a rate tracking a rate of change of the speed of the conveyor. When full conveyor speed is detected, the motor speed control provides the second motor speed signal to the pump motor which operates the motor at speeds determined by the full conveyor speed. In addition, there are methods for generating pressure related and conveyor speed related motor speed signals and automatically switching between those signals as a function of the conveyor speed.

摘要： A module or dispenser for dispensing at least one liquid filament onto a moving substrate includes a nozzle body having a liquid supply port, a liquid discharge portion or end, and a liquid discharge passage having an orifice in fluid communication with the liquid supply port. The liquid discharge passage extends along an axis and the opening is shaped asymmetrically about the axis to provide a controlled directional movement of the liquid filament in a desired direction. The asymmetric shape may be formed by a notch or a chamfer or a stepped portion intersecting with the liquid discharge passage, or combinations of these features, or in other manners.

The wedge-shaped member extends in a radially asymmetrical manner around the liquid discharge passage. Four air discharge passages are positioned at the base of the wedge-shaped member. At least one air discharge passage is positioned adjacent each of said side surfaces and each of the air discharge passages is angled in a compound manner generally toward the liquid discharge passage and offset from the axis of the liquid discharge passage.

摘要： Methods and apparatus are disclosed for spraying powder into the interior of welded hollow can bodies from a spray gun mounted to the welding arm of a can forming machine. The spray gun can either apply a stripe of highly charged powder on the welded seam areas of hollow can bodies, or can simultaneously apply a coating of powder having a first thickness on the longitudinally welded seam areas and a second thickness less than the first thickness on the remainder of the interior surface. Air is vented off from the powder flow being transported through the welding arm so that the powder to air ratio is increased. Air is introduced at the downstream end of the welding arm to provide a suction force to help draw the powder flow through the welding arm and to increase the velocity of the powder flow for better tribo charging of the powder in the gun and to improve spray pattern stability. A flow of cleaning air through the powder spray gun prevents powder from collecting on the front surface of an offset nozzle secured to the spray gun. The gun assembly is affectively grounded to prevent arcing, and has an exterior shape which has been geometrically configured to improve powder coating of the can.
