Abstract:
A method for controlling an amount of material delivered during a material transfer. This method includes the steps of inputting a target amount for a material to be delivered from a source location to a target location, updating the target amount during the delivery of the material using a predictive model-based algorithm, and updating the predictive model-based algorithm based on process performance data using a recursive least-squares procedure. An adaptive selection algorithm which is used to determine whether at least one previous predictive model-based algorithm parameter should be replaced with at least one new predictive model-based algorithm parameter in order to adapt the predictive model-based algorithm in response to a process change. A method for overlapping a delivery of at least one independently measured material with a delivery of a main material during a material transfer process.

본 발명 지하를 운행하는 운송수단을 위한 구조물이나 터널을 구축하기 위해 지면에서 지하로 수직경로를 굴착하고, 상기 수직경로의 끝단부에는 수평방향으로 터널을 형성하기 위해 수평경로를 굴착하여 발생된 토사를 운송수단을 통해 외부로 배출함으로써 발생하는 토공량을 관리하기 위한 굴착 토공량 관리방법에 관한 것으로서, 더욱 상세하게는 상기 운송수단을 통해 외부로 토사가 배출될 때, 토사가 만차된 운송수단의 하중과 지면의 토사 핏(Pit)에서 배출 후 공차된 운송수단의 하중차이를 측정하여 데이터로 정리하는 것이 특징인 굴착 토공량 관리방법에 관한 것이다. 상술한 바와 같이 본 발명 굴착 토공량 관리방법은 광차의 하중을 로드셀에 의해 측정하므로 설치와 측정이 매우 간단하며, 또한 굴착된 토사를 최종 배출하는 단계에서의 만차된 광차의 하중과 최초 공차된 하중을 측정하기 때문에 매우 정확한 값을 산출할 수 있다는 등의 현저한 효과가 있다.
Abstract:
An system for dispensing liquid and solid materials comprises a tank (14); one or more liquid feeders (12) configured to dispense one or more liquids into the tank; a powder hopper (22) comprising a powder inlet, a powder outlet, and a valve (28) configured to open and close the powder outlet, the powder outlet being coupled to the tank (14); one or more powder feeders (26) coupled to the powder inlet of the powder hopper; a first scale (24) configured to measure the mass of powder dispensed into the powder hopper; a second scale (16) configured to measure the mass of the liquids dispensed into the tank; and a control system (18) configured to control the dispensing of liquids and powders based at least in part on the mass measurements from the first and second scales.
Abstract:
The invention relates to a device comprising a dosing unit (400) for releasing a substance and scales (427) for determining the amount of the substance released. The dosing unit (400) comprises a storage container that contains the substance to be released. The dosing unit (400) is mounted on the scales (427) in such a way that the scales (427) measures the weight of the dosing unit (400). As the scales (427) measures the weight of the dosing unit (400) including the storage container and the substance, the amount of the substance released can be exactly determined by subtraction.
Abstract:
The invention concerns a method for filling a container with the net weight of a product using a filling element arranged to introduce the product in the container when the latter is borne by a force sensor. The invention is characterised in that it comprises at least a cycle including steps which consist in: providing a container on a force sensor; commanding a flow of product by the filling member, repeatedly timing the flow of product starting from the time the flow is commanded; measuring at least at distinct first and second reading times a value of a signal delivered by the force sensor; calculating an average flow rate of the product in a time interval separating the reading times; performing at least a calculated evaluation of a filling time based on the calculated average flow rate and a reference weight; commanding the product flow to be stopped when the flowing time of the product is equal to the evaluation of the filling time.
Abstract:
The present application relates to a device for dispensing a determined weight of a cosmetic product into a receptacle from a reservoir, the device comprising at least one electromechanical member capable of moving an amount of cosmetic product from said reservoir installed in the device to a dispensing zone of said device where said amount of product may be transferred through a nozzle into the interior of the receptacle received in said dispensing zone, the device comprising a controller configured to deliver a control signal to the electromechanical member according to an error with respect to a setpoint corresponding to the determined weight of cosmetic product to be delivered, said error being determined on the basis of a weighing datum obtained by at least one weighing cell for the reservoir installed in the receiving zone, the device being characterized in that the controller is a reinforcement-learning controller.
Abstract:
Eine Vorrichtung zur Dosierung einer Substanz in einen Zielbehälter (Z) umfasst ein Greifwerkzeug (30), mit dem ein Dosierwerkzeug (40) aufgenommen und abgegeben werden kann, sowie eine Waage (50). Das Dosierwerkzeug (40) ist als Haftkörper, insbesondere in Form eines Glasstäbchens ausgebildet, welcher z.B. durch Eintauchen in eine Substanz (S) mit dieser benetzt wird, so dass eine kleine, von der Waage (50) messbare Substanzmenge am Dosierwerkzeug haften bleibt. Nach Aufnahme der gewünschten Menge an Substanz mit dem Dosierwerkzeug (40) wird letzteres, inklusive der daran anhaftenden Substanz (S), in den Zielbehälter (Z) abgegeben. Eine Steuerung (100) steuert die Waage (50) und das Greifwerkzeug (30) und entscheidet, ob die mittels Dosierwerkzeug (40) aufgenommene Menge an Substanz verwendbar ist oder ob mehr Substanz aufgenommen oder das Dosierwerkzeug verworfen und mit einem frischen Dosierwerkzeug etwas weniger Substanz aufgenommen werden soll. Dies erlaubt eine Dosierung von sowohl flüssigen als auch pulverförmigen Substanzen im Milligramm- und sogar Sub-Milligramm-Bereich.
Abstract:
A feeding apparatus consisting of a supply hopper (100) and a weighing hopper (150). Feeding of material from the supply hopper (100) to the weighing hopper (150) varies between a bulk feed rate and a fine feed rate by varying the size of the opening of the supply hopper aperture by independently controlling the two closing flaps (410,420). There may be more than two flaps, and the flaps may vary in size relative to one another.
Abstract:
The following invention presents a novel apparatus for a gradual and controlled feed of bulk material to a weigh hopper. The batcher comprising inter alia a retaining hopper containing at least a portion of the bulk material to be weighed comprised of at least one aperture outlet through which bulk material is supplied gradually to said weigh hopper. The size of said aperture is controlled by a means of a set of a first closeable valve and a second closeable valve. The apparatus comprising also a weight hopper adapted to receive said bulk material in a controllable manner and a weight comparator adapted to compare the weight of the bulk material in said weigh hopper with a first, second and third predetermined values and to transmit a plurality of a first, second and third weight control signals to said first and second valves wherein said weight of the bulk material is equal or grater than said predetermined values and a forth control signal is provided whereat all material is dropped from the weigh pan.
