    Abstract: Additive manufacturing apparatuses and methods are provided. A coater having a rake moves above a build platform. A sensor measures topography of the build platform. A rake control unit receives the topography, determines (based on the topography) an adjustment of the rake's inclination relative to a reference plane as the coater moves from a first position above the platform to a second position above the platform, and sends command signals to a motor based on the adjustment. The motor adjusts an inclination of the rake relative to the reference plane as the coater moves from the first position to the second position.

  • Publication number: 20090045538
    Abstract: Embodiments of the present invention teach a method of controlling a screw in a two-stage injection unit and a system for implementing the method. For example, a method of controlling a screw in a two-stage injection unit, the method executable at a computing apparatus associated with the two-stage injection unit is disclosed. The method comprises receiving an indication of an operational parameter associated with the screw of the two-stage injection unit; based on the indication of the operational parameter, determining a target speed (STARGET) for the screw, the target speed (STARGET) being sufficient to enable the screw to produce a required amount of material in a molten state; causing the screw to rotate at the target speed (STARGET), thereby causing the screw to operate in a substantially continuous manner.

  • Patent number: 7287971
    Abstract: A load determining device for an electrically-operated injection molding machine in which a load exerted on a movable part is detected based on the motor current or by an observer, with removing the influence of motor temperature. Upon start of continuous molding, a maximum load detected during retreat motion of an ejector or movable part is stored as a reference value Lr0. In every molding cycle, a maximum detected load Lra during the retraction of the ejector is determined. In the next molding cycle, load La detected during advance of the ejector is corrected based on the reference value Lr0 and the maximum detected load Lra to eliminate the influence of motor temperature rise, thereby determining the load Lfx(n) during the advance of the ejector. When there occurs a change in temperature of the ejector driving motor, the load detected based on the motor current or by the observer varies even if the actual ejector load is constant.

  • Publication number: 20040217498
    Abstract: An innovative robotic foam application process that integrates system communications, non-contact vehicle insertion point locations, and applications controls to accurately dispense a two-component structural foam at a high volume and flow rate. The process begins by first inserting a baffle within the support structure. After an electrocoat application and bake, the baffles expand and are sealed within the support structure to form cavities having a fill hole. A hydraulic driven robotic dispensing system equipped with a high-pressure static mixer senses the respective fill hole, moves a robotic arm to a location sensed, and injects a high volume of mixed two-component viscous material within each of the respective located fill holes at a high fill rate. After dispensing, the viscous material undergoes an exothermic curing reaction to cure and is expanded to substantially fill each cavity.

  • Publication number: 20040170719
    Abstract: A pair of hoses connects directly from the feed pumps to the extruder without utilizing a PCV (pressure compensating valve). Each feed unit has automatic air pressure relief through a solenoid valve on top of the feed unit so that the unit does not stall at full static line pressure. When the dispense valve at the extruder is shut off, air pressure to the air motor is dumped. A pair of electric eyes is utilized—the first signals the pump (by providing pressurized air) to provide pressure while the second actually opens the extruder when the article to be coated comes into position. The first valve is located only a short distance ahead of the second valve so that the line pressure does not have a chance to exceed the dynamic pressure before the extruder opens.

  • Publication number: 20040142056
    Abstract: By starting injection, resin pressure in front of the check valve is raised, and the check ring moves backward. Pressure of resin accumulated between flights of the screw prevents the check ring from moving backward, and the screw is kept freely rotatable to thereby make the backward speed of the check ring faster. Therefore, the check ring is brought into tight contact with the check seat quickly to close the resin path. Thereafter, the rotation of the screw is fixed, reduced pressure in the injection/dwell causes the screw to rotate in a normal direction, and prevents the resin from being pressed toward the front of the check valve.

  • Publication number: 20040091567
    Abstract: A screw is rotated at a set speed and retreated by performing back pressure control for keeping a resin pressure at a set pressure. When the retreat position of the screw reaches a change point set nearby a set metering completion position, the back pressure control for keeping the resin pressure at a set resin pressure is stopped. A command for positioning the screw at a metering completion position is output to position the screw at the metering completion position. At the same time, when a screw position reaches the change point, the screw is reversed by a set value at a set speed.

  • Publication number: 20040091561
    Abstract: The retraction of the screw is controlled on the basis of the pressure deviation between the set resin pressure and the detected resin pressure. Furthermore, the screw is caused to rotate at a set speed. Moreover, when the deviation between the metering completion position and the current screw retraction position drops to a value that is equal to or less than a set value, control of the retraction of the screw based on the pressure deviation is stopped, and the control is switched to positioning control based on the positional deviation. Furthermore, a screw rotational speed command in which the pressure deviation component between the set resin pressure and the current resin pressure is corrected from the screw rotational speed component that is decelerated in proportion to the positional deviation is determined and output.
