Abstract

EL OBJETO DE LA PATENTE ES UN DISPOSITIVO PARA LA MEDICION NO DESTRUCTIVA DE LA FIRMEZA DE FRUTOS. EL DISPOSITIVO SE COMPONE DE UN ARBOL (1) DE GUIADO DE LOS DESPLAZAMIENTOS VERTICALES DE UN BRAZO HORIZONTAL (2), QUE ES PORTADOR EN SU EXTREMO LIBRE DE UN ELECTROIMAN (4) DE RETENCION DE LA MASA (5) Y DE UNA CELULA FOTOELECTRICA (6) MONTADA SOBRE UN PUENTE (7), DE FORMA QUE EL RECEPTOR Y EL EMISOR QUEDAN A UN LADO Y OTRO DEL FRUTO (8) ESTACIONADO SOBRE UNA CELULA DE CARGA (9). LOS MOVIMIENTOS, REGIDOS POR UN ORDENADOR, SE INICIAN CON EL DESCENSO DEL BRAZO (2) HASTA QUE EL HAZ LUMINOSO DE LA CELULA FOTOELECTRICA (6) ES INTERCEPTADO POR EL FRUTO (8), EN CUYO MOMENTO SE DETIENE EL DESCENSO DEL BRAZO (2), CAE LA MASA (5), IMPACTA SOBRE EL FRUTO (8) Y LOS EFECTOS SON REGISTRADOS POR LA CELULA DE CARGA (8) Y VALORADOS POR EL ORDENADOR MEDIANTE UN PROGRAMA ADECUADO. A CONTINUACION SE INICIA EL ASCENSO DEL BRAZO (2) Y PUEDE COMENZAR DE NUEVO EL CICLO OPERATIVO.THE OBJECT OF THE PATENT IS A DEVICE FOR THE NON-DESTRUCTIVE MEASUREMENT OF THE FIRMNESS OF FRUITS. THE DEVICE IS COMPOSED OF A TREE (1) TO GUIDE THE VERTICAL DISPLACEMENTS OF A HORIZONTAL ARM (2), WHICH IS CARRIED AT ITS FREE END OF A MACHINE (4) AND A PHOTOELECTRIC CELL (6) MOUNTED ON A BRIDGE (7), SO THAT THE RECEIVER AND THE EMITTER ARE SIDE AND OTHER OF THE FRUIT (8) PARKED ON A LOAD CELL (9). THE MOVEMENTS, GOVERNED BY A COMPUTER, BEGIN WITH THE DESCENT OF THE ARM (2) UNTIL THE LIGHT BEAM OF THE PHOTOELECTRIC CELL (6) IS INTERCEPTED BY THE FRUIT (8), AT WHICH TIME THE DESCENT OF THE ARM STOPS (2 ), THE MASS FALLS (5), IMPACT ON THE FRUIT (8) AND THE EFFECTS ARE REGISTERED BY THE LOAD CELL (8) AND VALUED BY THE COMPUTER THROUGH AN APPROPRIATE PROGRAM. THEN THE ARM RISE BEGINS (2) AND THE OPERATING CYCLE CAN BEGIN AGAIN.
