Abstract
An apparatus for forming compacted powder products. The apparatus includes a powder supply system and a compacting station. An emitter emits an input X-ray beam having a predetermined emission intensity. An output detector detects an output parameter representing an output intensity of the X-ray beam which passes through the powders. A reference detector detects a reference parameter representing the effective intensity of the X-ray beam generated. A control unit is programmed to compensate the output parameter by means of the reference parameter and to generate a control signal representing the density detected and to control the powder supply system by means of the control signal.
Claims19
A method for forming compacted powder products, comprising the steps of:
- a) depositing a soft powder mass on a supporting table and delivering the soft powder mass to a compacting station;
- b) compacting the soft powder mass against the supporting table to obtain the compacted powder product;
- c) generating on a first side of the powders an input X-ray beam having a predetermined emission intensity;
- d) detecting, on a second side of the powders, opposite the first side, an output parameter representing an output intensity of the X-ray beam, which passes through the powders;
- e) measuring a thickness of the powders and determining a density thereof as a function of the emission intensity, the output intensity, and the thickness and type of the powders,
- f) detecting on the first side the powders a reference parameter representing an effective intensity of the X-ray beam generated;
- g) compensating the output parameter using the reference parameter to determine the density of the powders;
- and
- h) generating a control signal representing a detected density and controlling the step of depositing the soft powder mass using the control signal.
An apparatus for forming compacted powder products, comprising:
- a powder supply system configured to deposit a soft powder mass on a supporting table;
- a compacting station configured to receive the soft powder mass and to compact the soft power mass against the supporting table to obtain a compacted powder product;
- an emitter mounted on a first side of the powders and configured to emit an input X-ray beam having a predetermined emission intensity;
- an output detector mounted on a second side of the powders, opposite the first side, and configured to detect an output parameter representing an output intensity of the X-ray beam which passes through the powders;
- a measuring device configured to measure the thickness of the powders;
- a control unit operatively connected to the emitter, the output detector and the measuring device are programmed to determine the density of the powders as a function of the emission intensity, the output intensity, and the thickness and type of the powders;
- a reference detector mounted on the first side and configured to detect a reference parameter representing the effective intensity of the X-ray beam generated,
- wherein the control unit operatively connected to the powder supply system and to the reference detector and is programmed to compensate the output parameter by means of the reference parameter and to generate a control signal representing the density detected and to control the powder supply system by means of the control signal.
