 contact 32 of the first control relay 6 of the second pulse generator is connected to the first output of a normally open contact 36 of the third intermediate relay 17 and through a second normally closed Q indoor contact 37 of the third intermediate relay 17 with the second control winding of the third time relay 20, the second output of a normally open contact 36 of the third intermediate relay 17 is connected to the second terminal of the control winding of the third intermediate relay 17 and through a normally open contact 38 with a time delay pa opening one third time relay 20 and through normally closed contact 39 with time delay for closing the second time relay 19 with the second output of the normally open contact 35 of the second intermediate relay and simultaneously through normally open contact 40 with time delay for opening the second time relay 19 and through normally closed Kon, cycle 40 of the first control relay 4 of the first pulse generator is connected to the second output of the normally open contact 28 of the first intermediate relay 15, which is connected via the normally closed contact 41 to the output With a time delay for closing the control relay by the previous actuator (not shown), a normally closed contact. 42 of the second control-relay 5 of the second pulse generator and the normally closed contact 43 with time delay for closing the first time relay is connected to the second output of the normally open contact 22 of the first control relay 4 of the first pulse generator.

The second terminals of the windings of the control relays 4, 3, b, 5 are connected to the common point of the photo cells 12, 11 and 14, 3 through diode connected in opposite directions. 7, 10, 9. In series with the diode 9, the normally closed contact 44 of the third intermediate relay 17 is switched on.

As the photo cells II-14 pass by, the timber 45 closes them from the lighting lamps 46 and 47.

The device works as follows.

When a timber of this length enters the zone of installation of length sensors, contacts 22 and 23 (Fig. 1) of relay 4 and 5 (Fig. 2) are closed, as a result of which relay 18 triggers, which remembers the fact that it was their timber that was in the zone of length sensors, producing thus, the code for resetting this timber to this drive and preventing contact 43 from entering this code to intermediate relay 17, which acts as an output memory element of the transit code register built on intermediate relays and time relays. When this timber is displaced from left to right by the conveyor (Fig. 2) and its rear end is between the photocells 14 and 13, the control relay 6 is activated. As a result, the contact 26 of the relay 18 and the contact 27 of the relay 6 are simultaneously closed. an actuator 1, the action of which the timber is in its intended drive. Upon entering the installation zone of the length sensors of the first transit timber of small length, at the moment the control relay 4 is activated and the contact 22 is closed, the third intermediate relay 17 is activated, which remembers the fact that the length of the first transit timber of the small length entered the installation zone, contact 44 (fig. 2) eliminates the possibility of triggering control relay 5 and the closure of its contact 23. This eliminates the possibility of triggering relay 18, therefore, the possibility of triggering control relay Complementary mechanism 1. At the entrance to the specified zone of the second transit timber of small length, the second intermediate relay 16 is already triggered in the manner described, and at the entrance

the third is the first intermediate relay 15. At the time of the withdrawal of the first transit wood of small length from the sensor installation area, when its rear - Topeu is between the photo cells 14 and 13, the relay 6 pulses the relay 6 and de-energizes relay 17 by its contact 32. the rule is implemented: the timber is gone — the information about it is erased. After completion of the act of erasing, information about the second and third timber of small length is automatically shifted from relay 16 to relay 17, and from relay 1J5 to relay 16. At the time of leaving the specified zone of the second named forest material, the second code is erased Timber - the third code. And in this case, the device works in accordance with its purpose, passes short timber by.

In the case of entering the zone of installation of sensors of timber 45 is larger than the zone, the prohibition of code entering 0 on relay 18 is performed by controlling relay 5 through its contact 23, which is open at the moment of contact closure 22.- Instead of relay 5 in the manner already discussed, the code of long timber goes to an intermediate relay 17, and then erased by pin 32 at the moment the timber leaves the sensor installation area. As a result, and in this extreme case, the device reliably performs the function assigned to it, passes the timber 45 past.,

Thus, the device recognizes its length and in this case generates a signal to turn on the actuator, and the appearance in the installation area of the sensors of length of timber of a different length, greater or less than the specified, responds by prohibiting the actuation of the actuator. As a result, the disturbance in the form of a random occurrence in the said zone of foreign timber is no longer dangerous, and it is also possible to arrange the drives along the conveyor in any order of alternating lengths of timber stored in them 45.

The proposed device makes it possible to increase the noise immunity of the timber sorting complexes by length, thereby allowing to improve the quality of my sorting.
