(54) AUTOMATIC FOR SORTING EGGS BY WEIGHT

The invention relates to the field of food industry.

According to the main author. St. No. 371744 a machine for sorting eggs by weight is known, which includes a feeding conveyor; a device for addressing eggs, consisting of a distribution conveyor equipped with valves located above the conveyor belts of sorting eggs; weighing mechanism, equipped with a weight sensor with a signal classifier, connected through a block of delay lines with the mechanism of opening the valves of the distribution conveyor; A clock pulse generator, which is related to the mechanism of transferring it.

The purpose of the invention is the improvement of the well-known automaton and the increase in the "reliability of sorting" hits into weight categories.

This is achieved by the fact that each delay of a pneumatic signal is composed of n pneumatic relays performing repetition and interconnected so that the input of each successive relay communicates with the previous one through a two-valve controlled pulsator. element, with the atom entering the first relay through a similar two-valve element connected to one of the outputs of the signal classifier, and

the output of the last relay is communicated with the output channel of the delay line through a switch controlled by the clock generator and reporting the output channel

delay lines with the atmosphere when changing the clock pulse.

The block of 7 delay lines is composed of several lines, which ensure the shift of the input signals by 1, 2, 3, respectively. .. n weighting cycles. The pneumatic signal delay line, / for example, three takKta consists of three pneumatic relays 11-13, performing the repetition operation, three two-valve elements 14-16, controlled from the generator 9 clock pulses, and the switch / 7. An example of a two-valve element may be a combination of a container and two valves at its inlet and outlet. The valves operate in such a way that, if one is open, the second is closed at this time. The input of each relay, for example 12, communicates with the output of the previous relay // via a two-valve element 15, while the input of the First relay 11 is connected to one of the outputs of the classifier 6 signals through the same two-valve element 16, and the output of the last relay 13 is connected to the output channel delay lines through a switch 17, which is also controlled from the generator of 9 clock pulses and which connects the output channel of the delay line with the atmosphere when the clock pulse changes. The pneumatic // - 13 relays can be replaced by other pneumatic elements that perform the repetition operation. The machine works as follows. The egg transfer mechanism removes the 1st egg from the feeding conveyor, puts it “and the weighing mechanism 5, and then onto the distribution conveyor 2. The pneumatic signal from the egg weight sensor goes to the classifier 6, the latter, depending on the signal size, sends a command to the Mechanism 8 to open the valves 3 distribution conveyors 2. In order for Valve 3 to open at the very moment when the Ego is over the discharge conveyor 4 of its fraction, the delay line 7 block 7 provides a delay for the command from classifier 6 to open valve 3 until the egg approaches the conveyor 4 of this fraction. The valve 3 of each fraction has its own delay line, which provides a shift of the command signal by /, 2, 3 ,. . .p cycles, depending on the number of weight categories, which need to divide the incoming flow of eggs. The clock pulses necessary for the operation of the posterior lines, synchronously with the movement of the egg, come from the generator &. The delay of the pneumatic signals is as follows. During the passage of the delay line, the single signal P 1 is supplied from the clasoifier 6. At the same time, the 9 clock generator (the pulses give the signal of the RP 1, the input valve of the element 16 opens and the output valve closes, and pressure P sets in the container 16. At the end of the VZVeshi.ViNi clock signal Rc is reversed and becomes zero, the inlet valve of the element 16 is closed and the output valve opens, the compressed air located at the input of the element 16 of the element 16 enters the relay //. from the pressure required to activate it is turned off. At the output of relay 11, signal P1 appears. | At the next occurrence of the clock signal Pt2 1, the output valve of element 16 closes, pressure is remembered in the control chamber of the relay, and its output is conserved. Since the signal Pi2 1 opens the input and closes the output valves of the element 15 at the same time, the pressure I 1 is established in the tank of the element 15. At I (2 O, the output P 1 appears at the output of the relay 12. Similarly, when P / h 1 is filled with the capacitance of the element 14, and Sc p / z O, at the output p When Pt4 I appears, the signal P 1 appears 13, the switch 17 Sogdin rm output channel 13 and the output channel of the delay line are only a single clock signal, so at R / C O the output signal of the delay does not pass , and passes only at P / 4 1Thus, the signal at the output of the delay line from the classifier 6 is supplied at PM 1, and the output of the delay line, equal to the actuator 8, enters RR P, 4 1. t. tacting vzveshivan.
