The invention relates to an automation technology for agricultural production, in particular to poultry technology, and is intended for counting objects, such as eggs.

The purpose of the invention is to improve the accuracy of the device.

The drawing shows a diagram of the device for counting items.

The device contains a step holder 2 fixed above the conveyor, to each step of which elastic, for example rubber, tanks 3-5, filled with graphite powder 6-8, are attached. At the ends of the containers 3-3, electrodes 9–14 in contact with the graphite powder 6–8 are included in one

from the shoulders of the bridges 15-17 constant

connected with the counter 18 for obtaining integral information on the number of eggs with the chart recorder 19 for obtaining data on the chart that reflects the dynamics of the production rate.

The ends of the containers 3-5, located directly above the conveyor, provided with elastic, for example, polyethylene, flags 20-22 with side, for example, parabolic notches 23-26. Items 3-17 relate to sensors, and flags 20-22 perform the functions of probes interacting with objects.

The device works as follows.

When gravity rolls from the cells of the hen house to the assembly conveyor 1, they are continuously transported. At the same time, the transported eggs contact (enter into a tactile connection) with elastic flags 20-22, which have a rigid mechanical connection with 6-8 elastic containers 3-5 filled with graphite powder.

As a result of the contact of transported eggs with flags 20-22, they are bent together with elastic containers 3-5, and contact 1 (by appropriate (bending) compression of graphite powder 6-8. Deformation (compression) of graphite powder causes its abrupt (abrupt) change of the original electrical resistance. Since the ends of the containers 3-5 are fixed in contact with the graphite powder 6-8 electrodes 9-14, included in the bridges 15-17,

then at the time of tactile contact, we control 1) 1x objects (eggs) with the corresponding flags 20-22, followed by compression and, as a result, a sharp change in the initial electrical resistance of graphite powder 6-8 in elastic capacitances 3-5, an unbalance occurs bridges and, as a consequence, a sharp jump in the magnitude of the electrical signal (current) in its measuring diagonal.

This allows, based on the registration of these characteristics of current jumps (pulses) in the measuring diagonal of the bridge measuring circuit at the time of tactile contact of transported eggs with flags 20-22, based on the recalculation of these pulses, automatic recording of eggs on the conveyor 1 is possible. both the integral registration of the number of eggs with the help of counter 18, and the registration of the dynamics of the process of centered production with the help of self

Card 20. I

Due to the fact that the elastic flags 20-22, in contact with the eggs transported by the conveyor, are fixed together with 6-8 elastic capacitors 3-5 filled with graphite powder on the step holder 2, each of the flags 20-22 forms its own localized zone registration of the flow of test, excluding repeated (false) accounting and overlapping of information. The stepped holder provides the ability to create a distance between the flags in both the transverse and longitudinal directions of the working floor of the conveyor 1, i.e. Each stream of eggs is in contact only with a specific flag located on the flow path. The simultaneous contact of the same egg with two different flags is excluded, which ensures the elimination of the erroneous (repeated) recalculation of transported eggs. The presence of lateral parabolic notches 23–26 on flags 20–22 eliminates the simultaneous contact of the transported egg with two flags and, accordingly, a false recalculation and the random transverse position of the egg during its transportation. In this case (with the transverse position of the egg relative to the axial line of the conveyor)

The transported egg can have tactile contact with only one of the flags 20-22, since if one of the ends of the egg contacts one of the flags, then the second end of the egg will freely pass through the parabolic side cut of the other flag without coming into contact (tactile communication .).

This allows you to eliminate the false surplus of direct current, probes the performance of the device, to ensure the selectivity of the records of the eggs and the accuracy of the information obtained.

In the form of elastic flags that are rigidly connected with their upper part to the lower end of elastic containers with graphite powder, with their upper part rigidly fixed on the steps of the stepped holder, the outputs of the DC bridges of the sensors are connected to the inputs of the counters and the recorder.
