Machine for the inspection and sorting of fruits, which has, connected to a control system, an inspection unit (1) and ejection means (3) which eject the fruits inspected by the inspection unit (1) which do not comply with certain conditions pre-established by the control system. The product transport means have a plurality of rotating rollers (7) which rotate the fruits they transport as they advance, providing multiple views of said fruits to the artificial vision system (4), and a final section for the fall of the fruits with a curved surface with variable decreasing radius. The present invention also consists of a method to inspect and sort fruits which makes them rotate during their transport and inspection and sets their acceleration at the discharge from the machine through a curved surface with decreasing radius.

Provided is a color sorting machine in which decreases in yield resulting from the erroneous inclusion of good granules can be prevented by using different selection algorithms and operation ejector nozzle operations resulting therefrom in a first sorting part and a second sorting part. The machine is provided with: a binarization means for binarizing images of granular objects, a flaw-detecting means for extracting flawed parts of granular objects, a reducing means for reducing images of the external contour parts of granular objects, an enlarging means for enlarging images of the flawed parts of granular objects, and a synthesis means for synthesizing the reduced images of the external contours and the enlarged images of the flawed parts; wherein on the basis of an image obtained by this synthesis means, different air-jetting operations are established for the ejection means of a first sorting part and the ejection means of a second sorting part.

A process for differentiating conductive and/or ferromagnetic objects (O) in a material stream (2) comprises generating an electromagnetic alternating field by exciting a coil (S) with a sinusoidal voltage (ue(t)) of a constant frequency (fM), detecting an impedance change in the coil, which has been caused by an object (O), by determining at least one pair of values from a peak value (ÎM) and a phase shift (Φm) of the coil current (iM(t)) toward the excitation potential (ue(t)) of the coil, and determining the material by comparing the peak values (ÎM) and phase shifts (Φm) with reference values, wherein the peak values (ÎM) of the coil current (iM(t)) are calculated at at least one measuring phase angle (Φm) with the aid of a window comparator having a constant window width (Δi), wherein the time (ΔtM) between the window inlet point (p4) and the window outlet point (p6) of the coil current (iM(t)) is measured and the gradient of the current profile (iM(t)) is calculated from the window width (Δi) and the measured time (ΔtM) and the peak value (ÎM) is calculated from the gradient of the sinusoidal current profile iM(t) and its frequency (fM).

The invention relates generally to a method of determining the presence of a mineral within a material, such as a rock, a rock fragment, soil, sand or other geological material including: applying pulsed microwave radiation to the material; detecting radiation emitted from the material after the application of the pulsed microwave radiation; and analysing the detected radiation to determine the presence of mineral within the material. The invention also provides a method of sorting rock fragments into at least two streams using this method and an apparatus for carrying out the method.

The present invention relates to a method for separating mineral impurities from calcium carbonate-containing rocks by comminuting the calcium carbonate-containing rocks to a particle size in the range of from 1 mm to 250 mm, separating the calcium carbonate particles by means of a dual energy X-ray transmission sorting device.
摘要:
An optical cracked-grain selector that does not mistakenly identify normal grains of rice having no cracks as cracked grains due to the presence of the embryonic portion and/or surface scratches when optically identifying cracked grains of rice mixed in with material rice grains. An identification part in a cracked grain identification unit obtains a first rice grain image (having an embryonic portion and scratches) based on light passed through the rice grain that is received by a first CCD sensor built into a CCD camera of a photoreaction detection unit and a second rice grain image (having cracks, an embryo portion and scratches) based on light passed through the rice grain received by a second CCD sensor built into the CCD camera, acquires an image of the cracks by calculating a difference in the amount of light between the two rice grain images, and identifies a cracked grain.

To create a method that can be carried out using known broken glass sorting and detecting devices so the advantages of these devices with respect to robustness and interchangeability are retained but enhanced blow-out accuracy compared with the known method is made possible, it is provided that each of the light sources (7) emitting light beams (14) is associated with position data and with the instant of the activity of a light source (7), of which the position data is linked with the detected intensity values when the light beams (14) impinge on the photocell (18) associated with each light source (7) and this linked data is stored, together with the time data at the instant of detection, in a memory, preferably the control unit (10), and this linking data is linked to linking data obtained in the same way at a later instant, to produce a two-dimensional image of the broken glass material flow which is used as a basis for activation of the blow-out nozzles (11) by the control unit (10).
摘要:
A cost efficient and reliable method for online sorting of special glass which works independent of the color of glass and the shape of the material. The scrap glass stream to be detected is thereby irradiated by UV absorption or transmission values of the scrap glass stream, more specifically of the material-specific UV absorption edges and “UV-cutoff” frequencies., with reference values obtained before from standardized material laboratory inspections. If special glass is being detected, blowing nozzles disposed downstream of a detector unit divert the special glass toward a predetermined location where it is deposited. There can also be a system which includes a radiation source, a detection unit, an evaluation and control unit and a removal apparatus.

A paper handling system includes an acceleration conveyor having an acceleration belt operating at an acceleration speed. The system includes a pinning structure operably positioned to pin paper to the acceleration belt. The pinning structure is a rotary feeder which includes a plurality of flexible bristles extending radially from a roller into engagement with the acceleration belt. The speed of the acceleration belt is sufficiently high to create a suction phenomena such that when paper is pinned to the acceleration belt with the rotary feeder, the paper will be accelerated to a paper speed substantially equal to the acceleration speed. The system also includes a blower system operative to facilitate carrying the paper off of the acceleration belt across a transition gap between the acceleration belt and a product belt.
