SU925426A1 - Apparatus for sorting agricultural products - Google Patents

Description

The invention relates (to sorting devices and can be used in automatic control lines when sorting on a fraction and separating food and agricultural products from impurities.

A device for sorting products is known, comprising a single-feed mechanism, a light source, photo cells mounted on opposite sides of this mechanism and successively fixed along the height of the upright column, an actuator and a resetting device 1.

The use of such a device allows the separation of products only in size and does not ensure the separation of the flow according to quality.

Closest to the proposed device is a device for sorting agricultural products, containing a feeding roller conveyor with a drive, scattered light sources installed above the control zone, sensors of the monitored parameter and actuator {2.

However, such a device, due to the repeated interaction of the flow with the process equipment, does not reduce the loss of the substandard product.

The aim of the invention is to reduce the loss of products from mechanical damage.

The supplied slot is achieved by the fact that a device for sorting agricultural products, containing a feeding roller conveyor with a drive, sensors of a monitored parameter, scattered light sources installed above the control zone, and an actuator, is equipped with a command signal priority block, whose input is connected to sensors

15 is a controlled parameter, and the output is with an actuator, while the latter is made in the form of an inclined sectional trough installed with the possibility of rotating each section independently of one another on a common axis, and the sensors of the monitored parameter are located along the roller table.

FIG. 1 shows a general view of the device; in fig. 2 - view A of FIG. one; in fig. 3 - view B of FIG. one.

A device for sorting agricultural products, for example fruits, contains a feed roller 1, installed above the control zone of the source 2

30 scattered light, a discriminating device consisting of a row of sensors 3 (a, b, c, d) of a monitored parameter, and an actuator 4 associated with it, while sensors 3 are located along the roller table 1, and mechanism 4 is made in as an inclined sectional trough, which is mounted to rotate each section independently of one another on a common axis 5. Each section interacts with electromagnetic pushers b. The number of sections is equal to the number of sensors 3.

In addition, the device contains a block 7 for issuing a priority command signal, the inputs of which are connected to the outputs by the sensor 3 of the parameter being monitored, and the outputs to the corresponding sections of the mechanism 4 by means of the pushers Q, the spring 8 of the section returning to the initial position and assemblies 9 .

Sensor Za is designed to detect particulate matter and substandard conditions; SensorI1K 36 is for recognizing fruits that are not standard in size; Sensors Sv and Cr to detect non-standard fruits, respectively, in density and shape.

The device works as follows. J

The analyzed flow is supplied by the roller table 1 to the control zone, where it is exposed to the effects of sources 2. The recognition tool sequentially analyzes 1 fruit rotating on the roller table in accordance with a predetermined recognition algorithm. Sensor Z, which is set to detect impurities and substandard, in the presence of an object of this class in the control, issues command impulse through block 7 to the left or right pusher 6 of the corresponding engine 4, respectively. The passing pulse through block 7 is fixed and is a "prohibition on pulses follow. The duration of the prohibition is proportional to the distance from the sensor that first detected the separable class to the boundary of the control zone of the discriminating device. In this case, the command signal from block 7 arrives at mechanism 4 with the time delay necessary for moving the monitored product 10 from the sensor to the center of the corresponding section. When a signal arrives at the pusher 6, the interacting section overturns, directing the fruit to the corresponding collection 9.

After the pulse is removed, the spring 8 returns the section to the initial position. The piece feeding of fruits with an interval between them, not less than the length of the section, ensures strict separation into fractions.

Similarly, the sensor 36 analyzes the flow of fruits in size and when the controlled fetus deviates from the requirements

The GOST to the seed material issues a command signal through block 7, respectively, to the left or right corresponding pusher 6. Tilting the corresponding section drops the fruit into collection 9.

The sensors Sv and Zg recognize non-standard fruits, respectively, according to their density and shape, their removal into collections of non-standard fractions.

The end result of the sorting is the ideal fruit flow, which fully corresponds to the sorting task set — post-harvest, pre-sowing or commercial. In this case, the sorting objectives determine the sequence of the sensors (the most undesirable class in the stream is separated first), their number and interchangeability.

The final number of fractions is generally determined by the type of treatment. So, after the post-harvest treatment, two fractions are obtained - solid impurities and healthy, during the commodity processing also two fractions are substandard and healthy, during the pre-sowing treatment three size fractions are required by standard, three fractions by density and three fractions by shape. Thus, the number of fractions obtained during simultaneous sorting is 8-10. In this case, the use of a conventional algorithm for sequentially dividing the source flow by one actuator into two necessitates the need for at least seven actuators. In the proposed device, the final nine fractions are provided with a total of four execution sections.

The use of such a device increases the efficiency of the sorting process by 30–40%, reduces the energy consumption and the amount of necessary technological equipment by 1–2–2 times, while manually re-sorting commercial and seed materials is excluded.
