Abstract

The invention relates to electrical engineering and can be used as a sensor that performs the logical operation Memory. The purpose of the invention is to expand the functionality. When the slider (P) 9 moves up, the switching stop (PU) 2 enters the slot of the contactless switch (BP) 1. At the initial moment of time, the cut-off section 5 of the switching stop 2 is located above the sensitivity zone of BP 1, section 6 connecting the switching on and off sections 4.5, moves parallel to the stroke N 9. At the end of stroke P9, the switching-on segment 4 PU 2 As a result, the PSU 1 turns on and sends a signal to the power amplifier 7, which changes the polarity of the signal to the electric motor 8. P 9 begins to move in the opposite direction until the tripping section 5 crosses the sensing zone. elnosti BS 1. BS 1 is turned off, a signal to the power amplifier 7, which changes the polarity of the signal supplied to the motor 8, and R 9 changes the direction of movement.

Description

The invention relates to electrical engineering and can be used as a sensor, which sensitizes the logical operation Memory,

The purpose of the invention is to expand the functionality by providing a memory.

FIG. 1 shows a block diagram of the reversing of the electric drive using a slit-type contactless switch with a switch nm-stop; FIG. 2 - contactless switch with a switching stop switch 01ts, the edge of which has the shape of a broken line; Fig. 3 shows a contactless switch with a switch, a stop, the switching edge of which is made in the form of a line at an angle to the movement of the mechanism

The contactless switch 1 is of the slash type, its switching support 2 is designed so that the switching edge 3 has the shape of a broken line in the form of two segments - switching on 4 and turning off 5, connected by a segment b and located perpendicular to the switching stop, and distance 6 between them is equal to the shielding area. The block diagram of the reversing of the electric drive, in which a contactless cere- cal switch 1 is used with switching GM with an emphasis 2, contains a power amplifier 7, an electric motor 9, the shaft of which is kinematically associated with the slider 9 of the machine drive. On the slider 9 a switching stop 2 is installed. As the slider 9 moves up, the switching stop 2 enters the contactless slit of switch 1, and at the initial moment of time the disconnecting segment 5 of the switching stop 2 is located above the sensitivity zone of the contactless switch 1 including 4 and disconnecting 5 segments, moving parallel to the motion of the slide 9. At the end of the stroke of the slide 9 upwards, including the segment 4 of the switching stop 2 crosses the sensitivity zone of the contactless switch 1j to the result which will switch contactless fir t is included and supplies the signal to the power amplifier 7, which changes the polarity of the signal supplied to the motor 8, the slider 9 starts to move in the opposite direction as long as the segment 5 TURNED OFF chayuishy crosses the zone

of the sensitivity of the contactless switch 15, as a result of which the latter opens and sends a signal to the power amplifier 7, which changes the polarity of the signal, the Diero goes to the electric motor 8, and the slider 9 starts to move in the opposite direction

For contactless switch. 1 (fig.Z) include 4 and disconnecting 5 segments are located on the same line. The burden of switching the on / off switch off and on depends on the angle of the switching edge to the movement of the fur. With him. Increasing the delay time between on and off. The use of a contactless switch makes it possible to refuse in the design from devices in which it is necessary to provide for the reversing of actuators from the second bes contact switch and logical processing unit.
