Abstract

Purpose of the invention disclosed in the present patent application of invention is to build a machine which performs simultaneously or almost the action of collection of the leaves from the cultivated area and the action of sorting the foreign/unwanted bodies by means of an artificial vision system and separating them using a mechanical equipment.

Description

Title: Harvester for leafy vegetables perfected with electronic sorter
DESCRIPTION
At the state of the art are known various type of harvesters for leafy vegetables, with different mechanic sorting devices able to sort directly on the field the good product from coarse foreign bodies, with different dimension, shape or weight than the product collected.
There are other electronic sorting systems applied on different types of harvesters, able to harvest fruits, tubers, roots or bulbs; whose quality is determined almost entirely by their color.
Actually, with all the sorting devices applied on this harvester you cannot remove all the foreign bodies on the field, but only the foreign bodies with different dimension, shape or weight depending on the mechanical sorter used (shaker devices, blower, aspirator). Therefore, an accurate sorting operation, that until now is impossible to perform directly on the field, is performed in a second time in the processing plants; this step causes the following negative outcome:
Possibility of micro contamination due to bacteria presents in the foreign bodies (mice - frogs) that remain inside the harvested product until the next sorting step
- Increase of labor and cost of the product
Difficulty in maintaining the cold chain
Further handling of the product with further damage (bruising of the leaf, broken leaf)
Application of sorting methods without high reliability (many factories still use the manual sorting, especially in the small business)
- Increase of the time between harvest and finished product use
Decrease of the product shelf-life (lack of control of the level of rot in the foodstuffs)
Consequent reduction of the possible export distance
Less possibility of dealing with markets with high level of quality standards
Purpose of the invention disclosed in the present patent application is to obviate the disadvantages of the state of the art described so far.
The invention is represented in the attached table in which we highlight the details:
01 - cutting/conveyor head
02 - mechanical sorting system
03 - artificial vision system
04 - deviation device
05 - rejected product container (5.1 rejected product conveyor)
06 - good product container (6.1 good product conveyor)
The harvester object of this patent application, which can be self-propelled, pulled or carried, is composed of a head (1) which include a cutting system (different depending on the type of crop) and a conveyor device (this also different depending on the type of crop) in order to cut the product and convey it in the sorters direction (2-3). The sorters devices (2-3) may be more or less complex but until now only the mechanical types has been used (2); in this case they are integrated or replaced with an artificial vision system (3). This fact can also work individually, without the aid of the mechanical sorting equipment. The machine presented in the drawing is equipped with the artificial vision system (3), that can be completed by various detour systems (4). The good product is diverted to a first container (6) or conveyor (6.1), the rejected product is diverted to a second container (5) or conveyor (5.1). Current harvesters are built for a very conservative audience, which prefers to invest in more traditional technology, developed to raise only the hourly output, rather than in machinery technologically complex but significantly improve the quality of the harvest. Therefore, manufacturers are activated to produce machines faster and more capacious thereby neglecting the quality aspect of the harvest.

Claims
