Description

Device for recording the consumption of electrical energy o. The like. The invention relates to a device for recording consumption of electrical energy or the like according to tariff. or statistical aspects, in which a switching part from a starting position of a measuring device, for. B. a Counter or a clock, is moved and by a second measuring device, e.g. B. a clock or a counter, after a certain time has elapsed or after a certain consumption after decoupling from a drive via a reset device trained cam is brought back to the starting position and at which the switching part advances a registration device only if its previous one The deflection exceeds or falls below a certain, preferably adjustable, limit would have. In the event that the switching part is driven by a clock and in each case according to Passage of a certain amount of consumption under the action of a counter in the starting position is returned, the faster the counter, the smaller its deflection runs, the greater the consumption. With very high consumption per unit of time, in which the deflection is smaller than the distance required for the recording device to advance is required, the registration would accordingly be omitted. The registration device would therefore fail precisely where it is on the re-. registration is particularly important.

The invention has the object, even with very small deflections of the Switching part still to force a reliable registration. According to the invention has in a device of the type mentioned at the outset, the cam disc has a recess such a shape that a on the example under the action of a spring in the initial position traceable return member attached, cooperating with the recess Pen or the like the switching part glue the entrance of the restoring element initially under the control of the registration device moved beyond its starting position unid the switching part only when the return element returns to its initial position got.

The invention is based on the examples shown in the drawings explained in more detail «earth.

A pawl i (Fig. I) forming the switching part is pivotable on one mounted by a timer, 2 driven arm 3. The latch can be two different Take positions, an effective position shown with a solid line a and an ineffective position indicated by dashed lines b. The: both positions are secured by a box device .1. Will arm 3 in the direction of the arrow moves against the stop 5, then the pawl i is brought into position i, if it is not already in this position. On the other hand, migrates Pawl i on the adjustable stop along a scale 6; over then she will folded into the inoperative position io. With 8 the stepping device is for a counter 9 denotes. It can only be switched when the latch is on is in position i. On a shaft ii of the arm 3 there is a type Heart disc 1? With which a return member 13 cooperates with a pin 13 '. The restoring element is controlled by an auxiliary motor 1.4, each according to. a certain Number of revolutions is temporarily switched on by a counter, against the retraction force of a spring 15 moves towards the shaft i i. The heart disc has an approximately wave-shaped incision 16. At 17, a slip clutch is designated.

The device works as follows: Assuming that the instantaneous consumption is small and the meter is running slowly, the auxiliary motor is only switched on when the pawl i has moved from the initial position drawn to past the stop j. Since it was brought into the ineffective position b while walking past this stop, it cannot advance the wheel 8 when the restoring member 13 is moved by the motor 1.1. During this process, in the manner known from heart disks, the logs 12 are first rotated into the position shown, which corresponds to the zero position of the pawl i, in the sense of the arrow drawn. Then the pin 13 ' penetrates into the cutout 16 and rotates the disc 1z and the pawl i in the direction of the arrow beyond the zero position. The switching tooth of the pawl wanders past the wheel 8 without adjusting this because the pawl is in the inoperative position b. When the pawl hits the stop 5, it is brought back into the effective position a. If the resetting element 13 returns to the starting position under the action of the spring i 5, when the switching pulse coming from the front counter has ceased. the disk 12 is brought into the illustrated zero position when the pin 13 ' comes out of the incision 16. During this movement, the switching tooth of the pawl i slides over the closest tooth of the wheel 8. without advancing this.

The movements of the shaft ii caused by the pin 13 'become carried out with sliding of the coupling 17. When moving the pawl i through the Stop 5 in the zero position has the particular advantage that any tooth clearance in your gearbox between parts 2 and 1; is balanced.

If the counter now runs faster in the following measurement, then it switches he turns the motor on before the pawl i has reached the stop. The latch stays deslialli in the effective position i. As before, the handle is now through the Parts 12 and 13 rotated back into the initial position shown and then over this Starting position also moved on to the stop 5 on the parts 13 'and 16. There : If the pawl is in the most effective position, wheel 8 is now uni one "Lahn switched. In] the rest of the process is the same as described above. The example shows. that even if the one covered by the jack i Measuring path is very small, i.e. smaller than the switching path. to switch the Wheel 8 is required. the counter g is switched correctly.

In the embodiment according to FIG. I, the pawl i always reverses with a retrograde movement back to the starting position. 1); e `skins i i harn here do not perform a full rotation, but for example an angle of about 16o- put back.

In the exemplary embodiment according to FIG. A, the shaft ii can also be brought into the starting position with forward reliting - if the tip 122 of the heart log>, 12: c11011 has wandered past your part 13 on the arrival of the Zälilerinil>, "- narrow the counter runs relatively slowly. If -the "counter is running faster, that is to say, when the counter input arrives, the tip 122 has not yet passed part 13. In this, the shaft ii is returned to the starting position with feedback 111. Since this mode of operation of such devices is known per se, it needs The only thing that should be emphasized is that the pawl i can only advance the ratchet wheel 8 when turning backwards in the direction of the arrow; when turning forwards, i.e. when turning in a direction opposite to the arrow, but slides past it without switching The heart disk i2 in this case has a special cutout 16, which has the effect that when the pawl i is rotated backwards, the pawl is moved past the drawn zero position in the direction of the arrow past the wheel 8 when the pin 13 'enters the cutout i6 , penetrates, however, it is brought back to the initial position drawn when the pin 1 3 out of the Au Section 1 6 again, the exit. As a result, in this embodiment, too, the wheel 8 is incremented if, with very high consumption per unit of time, the measuring path of the pawl i is smaller than the incremental path of the wheel B. If, however, the peak I2 # -,. When the meter pulse arrives, it wanders past your part 13 and when the meter pulse arrives, the pawl i is brought back to its starting position by rotating forward, then when the pin 13 ' penetrates into the cutout 16 and when it comes out of this cutout again, the pawl i always moved in the sense of a forward rotation. So that the cutout 16 is not rotated beyond the part 13 with very little consumption, a control disk provided with a cutout 18 for an interruption switch i9 of the timer 2 is attached to the shaft ii in a known manner, which stops the timer before the shaft ii has made a full turn before the cutout 16 has reached the area of the pin -3 '.

In the illustrated embodiment, the switching of the wheel 8 is effected by moving the pawl i beyond the starting position. Of course, you can also, conversely, leave the pawl i in the starting position during the shift and let the wheel 8 perform the required switching movement with respect to the pawl. In the embodiment according to FIG. This can be achieved in a simple manner by mounting the wheel 8, for example, on a pivotable lever which is moved by the auxiliary motor 1d i leads from position b to position a, if it is not already in this position.

The invention offers the advantage that even with very small measuring paths the latch i is registered correctly.
