Abstract

The present patent relates to an automated fruit and vegetable sorting machine which classifies products by weight and color range by using scales and other electronic sensors controlled through a processing plant.

Description

“FRUIT AND VEGETABLE CLASSIFYING MACHINE” [0001] This patent relates to an automated fruit and vegetable sorting machine that classifies products by weight range using load cells and other sensors / electronic actuators controlled through a processing center.

With the increasing sanitary requirements for the handling of fruits and vegetables for commercialization the market is increasingly looking for machines capable of performing tasks quickly, effectively and capable of maintaining a strict selection standard. In the case of fruits and some vegetables, the main selection criterion is the size range.

[0003] Size is usually part of a minimum standard and is classified in some ranges depending on the product. Normally its classification is given by unit weight, since for a single product usually the higher the weight the larger its physical size; or through physical templates that remove the product from the line whenever it is smaller than the template.

In the prior art there are some records on this subject, such as document MU 8600459 filed March 17, 2006 which refers to a fruit grading machine with mechanical scale system that classifies fruits by different weights. . Although it is a good concept, the use of scales with mechanical components compromises their reliability, as they may wear out, as well as limiting the speed of operation, since a minimum amount of time on the scale is required for the balance. spring compresses enough to stabilize.

In order to solve the above problem, the present fruit and vegetable sorting machine has been developed which aims to classify the products individually by size ranges (determined by their weight) in an automated way through previously registered parameters. , aided by load cells and other sensors necessary for their correct operation.

Description of the drawing.

The following description, and the associated figure, all given by way of non-limiting example, will make the fruit and vegetable sorting machine well understood.

Figure 1 is an isometric perspective view of the fruit and vegetable sorting machine with three grading lines and ten product outputs by weight range.

[0008] The present fruit and vegetable sorting machine is basically composed of the singulator (4), the electronic grader and the electronic control system.

The function of the singulator (4) is to align the fruits one by one and to distribute them correctly on the cup (cup) of the classifier, its traction is made by a set of gears with the classifier, manufactured with bent plate in conical shape. , utilizes a special flexible, cone-driven, gear-driven, tube-coupled chain system synchronized with the classifier, has superior guides in rigid material, responsible for keeping the fruit on the cones.

The sorter weighs the fruits through the load cells (1) monitored by a weight management software, thus analyzing each weight range and distributing it to the output corresponding to the configuration made in the system. This distribution is done through actuators fixed in a guide, which activate the fall of the product from each cup (bowl), distributing the fruit in the desired place. The movement of the bowls is through a chain where the rods are coupled with the cups (bowls that hold the fruits for weighing), pulled by an electric gearmotor with speed variator. The classifier can be manufactured with the required number of lines according to the application, and for each added line will have a load cell (1) and an actuator to direct the products to their respective output.

Every product outlet has a special lining spout to prevent damage to the products, then there is a belt type cross belt (2) that pulls the product out to the side stand (3) where it is deposited. the products for manual packaging.

[0012] The electronic control system is responsible for receiving the load cell weight information (1); output position evaluation according to the previously established weight range table and actuator actuation that will remove the product from the line considering the product travel time from weighing to the correct output.
