The ELECTRONIC SORTING

Electronic sorting is the automated process of sorting solid products using

cameras.

Depending on the types of sensors used and the software-driven intelligence of

the image processing system, optical sorters can recognize objects’ color,

size, shape, and structural properties.

The sorter compares objects to user-defined accept/reject criteria to

identify and remove defective products and foreign material from the

production line, or to separate product of different grades or types of

materials.

Compared to manual sorting, being subjective and inconsistent, optical sorting

helps improve product quality, maximize throughput and increase yields

while reducing labor costs.

BRATNE


The Electronic Sorting

Electronic Sorters feature four major components:

1. The feed system is to spread product into a uniform monolayer so products

are presented to the optical system evenly, without clumps, at a constant

velocity.

2. The optical system includes lights and sensors housed below the flow of

the objects being inspected.

3. The image processing system compares objects to user-defined

accept/reject thresholds to classify objects and actuate the separation

system.

4. The separation system, using compressed air pinpoints objects while in-air

and deflects the objects to remove into a reject bin while good product

continues along its normal trajectory.

The ideal sorter depends on the application, with the

product’s characteristics and the user’s objectives

determining the ideal sensors, software-driven capabilities

and mechanical platform.

The Working Process

JUL 2013 TRAINING ON ELECTRONIC SORTING8/11/2016

BRATNE


Feed System

SEA sorters are equipped with

small-sized standard hopper

An additional adequately sized

hopper must be installed, always

for proper operation.

BRATNE


Feed System

The throughput is controlled by

the program, which operates

according to the level sensors

fixed in the additional hopper for

low, med and high level control.

BRATNE


Feed System

Standard SEA sorters chute (60°)

has one side smooth and one

side with 54 channels (5mm

large each).

Available also the version smooth

+18 channels for big commodi-

ties (eg: chickpeas)

BRATNE


The Illumination & Sensors

Optical sorters require a compatible

combination of light and sensors to

illuminate objects and capture images

before the images can be processed

and accept/reject decision is made.

SEA sorters may have:

Commercial neon lamps (SEA-PIXEL),

Custom RGB LED (SEA-NEXT),

Custom white LED (SEA-CHROME

and SEA-NEXT) lighting systems.

BRATNE


The Illumination & Sensors

Lights, cameras, and sensors can be

designed to work within visible light

wavelengths as well as the near-

infrared(NIR) infrared(IR) and

ultraviolet (UV) spectrums.

The optimal wavelengths for each

application maximize the contrast

between the objects to be

separated. SEA LED LIFE:

100,000 h. minimum. Standard 150,000 h.

Based on proper electrical suppply

BRATNE


The visible spectrum is the portion

of the electromagnetic spectrum

that is visible to the human eye.

Human eye responds to wavelengths

from about 380 to 750nm.

CIMBRIA Srl designs and makes use

of high resolution custom CCD

Cameras and multiple optical

systems with high-tech objectives,

exclusive designed electronic and

software to collect, receive and

elaborate the images.

Inspection system - The Visible Spectrum


BRATNE


Beside the color sensors, NIR &

InGaAs CCD systems(or combination

of both) are used on SEA-NEXT and

SEA-CHROME sorters

The InGaAs (gallium indium arsenide) is

a common name for a family of

chemical compounds of three

chemical elements indium, gallium,

and arsenic

In electronic sorting, the InGaAs

alloy is used to indicate the Image

sensors for near infrared region is

applied.

Inspection system – NIR & InGaAs


BRATNE


SEA-NEXT & SEA-CHROME can

be offered with a combination of

cameras operating in the visible

and in the NIR or IR spectrum (up

to 4 cameras per chute).

Software Driven Intelligence

Once the sensors capture the object’s response to the energy source, image

processing takes over to manipulate the data to extract and categorize

information of specific features.

The user sets the accept/reject thresholds by the definitions of good and

bad flow. The art and science of image processing lies in developing

algorithms that maximize the effectiveness of the sorter while presenting

a simple user-interface to the operator.

New software-driven capabilities are constantly being developed to address the

specific needs of various applications.

SEA sorters can recognize each

object’s color, size and shape

as well as the color, size, shape

and location of a defect on a

product.

BRATNE


1. Color composition:

Hve = rainbow (7 colors from RED to BLUE)

Saturation = quantity of white in product color

Intensity = color intensity
