Description

one

There are known devices for switching on electric circuits along a predetermined cyclic program, comprising a housing with an adjustable circuit. In it, switchable, using IC elements, rotating drum with screw thread and ring mounted on it, 1 1 and guide element.

However, the known devices do not provide the possibility of simultaneous operation of several electrical circuits according to Individual c. Programs, which are automatic in the automatic mode and are complex in readjustment.

The proposed device differs from the known ones in that limiters are placed on the guide element, spring loaded probes are freely installed between the "flocks". Ka1zhdy probe is movable along the guide at vzai.madeystvyi screw thread drum and .povorachivats prodolynoy around the axis of the guide when reacting with (KOltsa1M1i. Each TaiKoe vsholnvno split ring and a flange, a wedge pad 1I akno arranged according to a predetermined program. A bracket is fixed on the device housing, supporting the probe in a high position above the B1I1NTx cutter | Coy drum as it passes under the action of a spring from the split-ring to the stopper.

This difference contributes to the possibility of simultaneous operation of several electrical circuits ("whether a group of circuits) in individual cyclic programs in an auto; math. Continuous mode, improving the accuracy of the calculated program and ensuring fast and simple changeover of the device to work on a new program of all or individual electrical chains.

FIG. 1 shows the proposed device, oh, bsch1y view ;, FIG. 2 - split ring; in fig. 3-6 are characteristic positions of the schute when it passes through the split ring.

The device for switching on the electrical circuits comprises a housing 1, a rotating drum 2 with a screw thread, an guide 3 and a rear panel 4.

In the screw channels 2 of the drum 2, split rings 5 are installed, which are held in NI.K due to the forces of friction caused by the springs of the U.ILIYA.MY cut / rings and rotate together with the drum.

Each | split ring 5 is made with

The wedge is the front part 6 and is provided with a shoulder 1 7, in which there is a WINDOW 8. The split ring is put on the drum from the end part and with its preliminary opening. On the guide element 3, stops 9, probes 10 and springs L are installed,

located between. Limiters 9 are fastened to the guide element by an einem. 12. Each probe W is made with a pivot / 5, has a sleeve with which it moves along 1 to 1 of the transmitting element and BOKpiyr of its longitudinal axis, and a tooth 14.

On the rear panel 4, there are switching electronic contacts 15, having pin 16 and plate 17, on which tooth 14 of the probe} 0 rests when it passes over the drum 2.

The setup of the device consists in mounting 2 cut rings 10 on the drum, fixing 4 electrical contacts 15j on the panel, which are placed opposite the split rings, fixing the elements 9 on the bottom of the plate (while the probe 10 is pressed by the spring 11 to the adjacent boundary and. is found in its initial screw groove) and installed on panel 4. Jf7.

The work cycle of the electric price center consists of two periods: the working period (when the electric circuit is closed) and the holding period (when the electric circuit is open).

The duration of the working period is caused by the time of pressing the X1 pin of the probe on the electric rod of the cell KOHTBIKTOB 15 and is determined by the time of the probe from the front of the bar: the cutting ring to the window 8 in the bead 7.

The length of the leriod was maintained due to the B (the probe probe loosened from window 8 to the limit of the reader (i.e., the probe returned under the action of spring | Ina // to its original position is practically a fraction of a second), the time it takes for the rotating drum 2 to rotate the size of the ring 5 and the time of passage of the wedge 1, the front of the ring to the momeite of the probe for its flange 7 (IB this moment will also be turned by its own terminal, will affect the electrical contacts - the beginning of the working period).

Thus, the device setup is applied in the installation on the drum of the corresponding equalizing ring 5, the length of the motor collar from the 1st front section to the cooTBeiTCTByeT window to the specified operating time of the 1TS6PI, and fixing the edge 9 on the guide element in the corresponding Location (more accurate (adjustment period 10 dimming is done by turning the split ring of the drum).

After the (ready IK operation of each electric circuit, the production of 1t is the pinch of the device, i.e., the IBO leads to | r: the drum 2.

The device works as follows.

Probes, 10 from the impact of the lateral pranas of the VITO1VYY.H grooves of the rotating drum are shifted (with the ino gage, compressed. Springs 11, and proceeds to their split rings 5. The split ring rotates

together with the drum 2, its wedge front 1 part 6 (ciM. 3) (goes up to the probe 10 and: picks it up, winding around the guide element 3, three of this shank 13

the probe acts on the rod 16 of the electrical contacts 15, the electrical circuit is closed, i.e. it is included in the work - the working period of the start has started. The probe 10 slides over the ring 5 and is held on it by the collar 7 (see Fig. 4).

As soon as the window 8 of the collar 7 will be against the probe, the probe that is no longer held by the collar, another 11 is thrown over the guide element T) IK to the stop 9 (see. Fig. 5), the electrical contacts i / 5 at the same time are broken (the period is 41its .

If the distance of the probe's passage over the drum to the limiter is small, then the Schul in this movement does not have time to turn around on:

and the opus / tails under the action of its weight, only after contact with the limiter 9, fall into its initial: 1 groove. With a large passage of the gauge over the drum, in order to avoid his IB sibling, there is some kind of sharmazhutoniyu screw screw, not reaching the limiter 9, the strap 17 is used, - for one gauge rests on the i3i i6OM 14. At the same time, the other probes move, providing Your job is cBOHiX elactric chains for individual cyclic programs.

With a continuous B1 rotating drum 2, electrical circuits are switched on according to a predetermined cyclic program in

automatic mode.
