FIG. 1 shows a block diagram of a device for monitoring the malfunction of the mechanism for turning the incubator trays; in fig. 2 - diagram of the signals of the working cycle of the working mechanism of the trays.

The device contains a command block 1 with switch 2, limit switches 3 and 4 sectors L turn trays, switch b starters, engine 7, gear 8, keys 9 and 10 for two inputs, coils 11 and 12 starters, three inverters 13, 14 and 15 , four conjunctors 16, 17, 18, and 19, for four-input, two formers 20 and 21 pulses., a 22 pulse generator, a counter 23 with a signaling node 24 and two 25 and 26 disjunctors, the switch 2 of the command unit 1 is connected to limit switches 3 and 4 sectors 5 rotations of trays, the switch 6 starters connected to the engine 7, transmitted through the gearbox 8 is associated with the sector 5 of rotation of the trays, the first inputs of the keys 9 and 10 are connected to the limit switches 3 and 4 of the sector 5 of rotation of the tray and the second inputs, as well as their outputs, are connected to the coils 11 and 12 of the starters, which are connected with the switchboard starters, the first disjunctor 25 of the counter 23 is connected with the installation input of the counter 23, the counting input of which is connected to the output of the second disjunctor 26 of the counter 23 whose inputs are connected to conjuncture 16, 17, 18 and 19, and the first inputs of the first 16 and second 17 conjunctors and the input of the first inverter 13 Points to the output of the command block 1, the output of the first inverter 13 is connected to the first, the inputs of the third 18 and fourth 19 conjunctors, the second inputs of which are connected to the generator 221 pulses and the second inputs of the first 16 and second 17 conjunctors, the third input of which are connected to the fourth input of the third conjunctor 18, in which the second fortirover 21 pulses and the output of the third inverter 15, the input of which is connected to the output of the second limit switch 3 and the fourth input of the fourth conjunctor 19, the third input of the fourth konj

junctor 19 is connected to the third input of the third conjuncer 16, the fourth input of the first conjunctor 16, to the input of the first imaging unit 20 pulses and the output of the second inverter 14, whose input is connected to the output of the first limit switch 3, and the outputs of the imagers 20 and 21 are connected to the inputs of the first disjunctor 25 .

The device works as follows.

A faulty tray is considered to be the mechanism that, when commanded by unit 1, does not rotate trays (limit switch, for example, 3, remains open), or does not turn to the end (jamming of trays), or is overdue for turning trays from one extreme position to Drugo (engine overload 7, or traction gear for racks).

The logic of operation of the device is explained as follows.

Let the command block 1 command a high level of potential at point d and point c, low potential O at point 6 to designate the rotation of the tray clockwise

Execution of the command (decoupling the limit switch 4) at the point

encode

high potential The position of the closed limit switch is coded

ABOUT

low potential

Accordingly, the command block 1 to turn the tray counterclockwise is encoded with a low level of potential O point and C and high 1 at a point.

The execution of this command is slave. The limit switch 3 is coded with a high level of potential 1 in the point.

The inverse of these signals will be d, "c" and €.

Claims (2)

In accordance with the above coding by the logical signals of the operation of the elements of the device, the cycle of operation of the healthy mechanism of turning the trays from which it is clear that the delay in turning the trays leads to an increase in the number of impulses of the generator 22, a plot of 3 and through conjunctors 16 and 18 (signals in, M) and disjunctor 26 the counting input of the counter 23, and the lack of rotation of the tray, after the filing of the next commantel. the absence of a change in the state of the limit switches 3 and 4 leads to the passage of the pulses of the generator 22 (Fig. -2, dashed lines) through conjunctors 17, 19 (signals G and K) disjunctor 26, leads to overflow of counter 23 and, as a result, will reflect node 24 alarm. In the case of executing a command to rotate the trays, the counter 23 is set to its initial position by pulses coming from the formers 20 and 21 through the disjunctor 25 to the installation input of the counter 23. Thus, the device provides automated control of the malfunctioning mechanism of the incubator tray rotation.
