Abstract:
A base valve, a base pump, a catalyst valve, a catalyst pump, a mixing chamber, a base cylinder connected to the base valve, and a catalyst cylinder connected to the catalyst valve. The base and catalyst cylinders are actuated so as to push base and catalyst fluids out of the base and catalyst cylinders, respectively, and into the mixing chamber. An electronic controller has a ready mode and a dispensing mode. In the ready mode, the controller i) activates the base and catalyst pumps and ii) signals the actuator to push or pull, in response to a dispense signal being asserted. In the dispensing mode, the controller a) deactivates the base and catalyst pumps, b) signals the actuator to stop pushing or stop pulling, and maintains a) and b) in response to the dispense signal being de-asserted. Other embodiments are also described.
Abstract:
A method and a device for compensating leakage losses in a line system, in which at least one positive displacement pump and at least one shut-off member are provided, wherein the method and device can be used for the isobaric metering of liquid plastic components and wherein the actual liquid pressure in the system is determined by way of a pressure measuring device and, when the shut-off member is closed is regulated to a pressure target value by actuation of the positive displacement pump, wherein the conveying loss rate of the positive displacement pump, which ensues to maintain the pressure target value when the shut-off member is closed is added to a target delivery rate in order to compensate for the leakage loss occurring at the corresponding pressure target value.
Abstract:
A method applies an at least two-component, curable and viscous material in the form of a material strand or a series of material points to a workpiece, an application process starting at an application start time and ending at an application end time, and the workpiece with the material applied thereon being destined for further processing which starts at a processing start time and ends at a processing end time. The mixing ratio of the components is varied by a control device depending on predetermined and/or measured parameters during the application process in such a way that the material applied to the workpiece can be processed at any point of the material strand or at any material point at the processing starting time.
Abstract:
A laminated nozzle assembly is provided. The laminated nozzle includes a first end plate having a first fluid inlet and a second fluid inlet, a second end plate, a plurality of nozzle plates positioned and clamped between the first end plate and the second end plate, a first fluid conduit in fluid communication with the first fluid inlet formed in one or more of the nozzle plates, a second fluid conduit in fluid communication with the second fluid inlet formed in one or more of the nozzle plates, a first orifice in fluid communication with the first fluid conduit formed in one of the nozzle plates, and a second orifice in fluid communication with the second fluid conduit formed in the same nozzle plate as the first orifice. The laminated nozzle assembly minimizes the number of nozzle plates and includes no more than eight, and preferably no more than five nozzle plates.
Abstract:
Apparatus and methods for dispensing small beads of a viscous, mixed fluid material formed by first and second viscous fluids. The apparatus includes first and second metering rods for moving in a reciprocating manner, such that the first metering rod extends into a first fluid passageway, and the second metering rod extends into a second fluid passageway. A mixing passage communicates with the first and second fluid passageways to receive the first and second viscous fluids from the first and second fluid passageways. A dispensing passageway is in fluid communication with the mixing passage, and dispenses a small bead of viscous, mixed fluid material formed by the mixed first and second viscous fluids. A control retracts the first and second metering rods to prevent drooling of the viscous, mixed fluid material from the dispensing passageway after a dispensing cycle.
Abstract:
A dispensing system has a head assembly affixed to a mixing chamber. The head assembly is fluidly interfaced to a first rod seat and the second rod seat. The first rod has a first rod head and the second rod has a second rod head. Distal ends of both rods are interfaced to a system for moving. In a closed position, the first rod head seats in the first rod seat and the second rod head is seated in the second rod seat, blocking fluid communication between the first input port and the mixing chamber and between the second input port and the mixing chamber. In an open position, the first rod head is separated from the first rod seat and the second rod head is separated from the second rod placing the first input port and the second input port in fluid communication with the mixing chamber.
Abstract:
The present invention discloses a feed system with a constant pressure. The feed system comprises a feed container which has a depressurize port mounted on its top, a intake port mounted at its side, and a feed port mounted on its bottom, contains a liquid material being a medicine or a liquid glue mixture; a intake structure which comprises a throttle pipeline and a throttle valve; a opening controller which connects to the throttle valve and the pressure sensor, for controlling the intake structure. The advantage of the feed system is to control the feed flow rate so as to maintain a constant during the feed process, particularly in the hybrid feed system. By steadily controlling the output flow rate, the mixed proportion is controlled to generate the product with the stable quality when two or more liquid materials must be mixed according to the specific proportion.
