Description

This invention relates to the automatic sorting of fish into size groups and can be used in the fishing industry.

A device for sorting fish is known, including sensors, logical and storage units, an actuator and a conveyor for moving fish.

A disadvantage of the known device is the low accuracy of the sorting of fish, with a possible change in the intervals for feeding work to the conveyor.

In order to improve the sorting accuracy when submitting work to the conveyor at different intervals, the proposed device is equipped with an additional storage unit located between the first sensor along the fish movement and the logic unit.

FIG. 1 shows a diagram of a device for sorting fish, in two projections; in fig. 2 - the same as a structural electrical circuit.

The device for sorting fish includes sensors 1-3, a logical block of elements 4-6, a storage unit 7, an actuating mechanism 8 of sorting, which is adjacent to the conveyor 9 and has drive electromagnets 10, 11 feeding the fish to transport i-ep 12.

The device is equipped with an additional storage unit 13 (trigger) located between the first in the course of the fish movement sensor 3 and the logic unit. Sensors 1-3 are mounted above the sources 14 of the light, which are mounted inside the feed conveyor 9 between its traction belts.

Sensor 1 gives permission to all three elements 4, 5, 6 of the logic block when the source 14 of light is blocked by the body of the fish.

The device works as follows.

The fish laid along the conveyor 9, and the movement of the latter overlaps successively sensors 1-3, issuing from one of its outputs enable signals for elements 4-6 of the logic block. At the same time, inverted signals are supplied from the second outputs of sensors 2 and 3, which prohibit elements 4 and 5 of the logic block, respectively.

The signal from sensor 1 triggers the front edge of the gate device 15, which gives permission for all elements of the logic block for a short time. The signals from the outputs of the logical block elements are fed to the input of the storage unit 7, where each of them is stored and stored until the size group of the fish to be sorted changes.

The signals from the elements of the logical block carry information about the belonging of the fish to the same size group, while the signal from element 4 contains the sign of the first, from element 5 - the second, and from element 6 - the third dimensional group.

The signals from the storage unit are connected to the input of the power amplifier unit 16, where they are amplified and then fed to the drive-electromagnets 10 and 11 of the actuator 8, depending on the size group of the fish being sorted, they are triggered or switched off simultaneously.

For example, for a fish of the first size group, a drive-electromagnet 10 is triggered, which acts on the actuator 8, which directs the fish to the left conveyor belt 12.

If the fish belongs to the second size group, then both electromagnet drives 10 and 11 are de-energized, and the fish is directed to the middle conveyor belt 12.

Upon receipt of fish of the third dimensional group, the drive-electromagnet I actuates, acting on the actuator 8, with the help of which the fish is directed to the right conveyor belt 12.

The fish is served in a mixed screen at different intervals. In the case of overlapping of sensors 1 and 2 with fish, second dimensional soil, the next fish with minimum interval can overlap sensor 3 and the actuator receives false information that the fish belongs to the third dimensional group, and in fact the fish belongs to the second dimensional group.

In order to ensure the accuracy of sorting, the fish is fed to the conveyor at such an interval that the first fish would approach the sensor 1 and the next fish would be in the zone of action of the sensor 3.

To ensure that the sorting accuracy during feeding of fish at any intervals, the additional storage unit 13 (trigger), receiving from the sensor 3 a signal that the fish has passed it, is brought to the "zero state, which prohibits the element 6 of the logic unit. Only the element 5 of the logic block participates in the measurement, since the permitting signals are supplied to all four inputs. Element 4 of the logic block does not participate in the measurement, since one of the inputs receives a inhibitory signal from the inverted output of sensor 2 blocked by fish.

As soon as the fish is removed from the zone of sensor I, the trigger of the trailing edge of the signal of the latter is placed in a "single position, giving permission for the element 6 of the logic unit.

In the following, the cycle repeats.
