Definitions

  • the invention relates to an electromechanical counter for the continuous numerical addition or subtraction of electrical impulses, consisting of one or more series-connected numerical rollers, each of which can be driven individually by the previous one, the initial numerical roller carrying a gear wheel, to which alternately those in the end region of an electromagnetic switch armature Attack arranged projections and thereby gradually turn the initial digit roll.
  • Electromechanical counters are known to be built and operated on the basis and technology of a relay.
  • a sink wrapped around a soft iron core is used for this.
  • the coil through which the electric current flows generates a magnetic field which attracts an iron plate articulated in the immediate vicinity of the soft iron core.
  • a corresponding mechanism is connected to this plate, which converts the pivoting movement of the plate into a rotary movement of the numerical roller. After the current flow in the coil has ceased, the mechanism is returned to its rest position by a spring which has been tensioned by the pivoting movement of the plate.
  • the magnetization of the iron causes a remanence after the current in the excitation coil of the magnet system has ceased, which has a disturbing effect in that the response values of the counter relay are shifted.
  • the response point in the following switching process is achieved by a significantly lower current flow, since the induced magnetic field builds up on the remanent field.
  • This residual magnetism can be so strong that the magnetic armature can no longer fall off exactly, or it even sticks to the magnetic core. In any case, considerable effort is required to compensate for these disadvantages, if one does not want to further worsen the electrical efficiency by further enlarging the effective air gap.
  • stepper motor It is also known to drive counters with stepper motors, the latching positions of the permanent magnetic rotor for the mechanical positioning of the digits roll towards it.
  • stepper motor requires a not inconsiderable effort for the motor itself, since, due to its functional principle, it has to be manufactured very precisely and also has to be coupled to the dial roller mechanism by means of a gear mechanism.
  • electrical control of the stepper motor requires precise single-phase or multi-phase pulse sequences, which can often only be achieved by complex electronic special circuits.
  • this control electronics also consumes electrical energy, the relatively good efficiency of a stepper motor is often deteriorated.
  • the invention is based on the object of providing a drive for an electromechanical roller counter which avoids the disadvantages of the known drives and is to be much simpler in construction compared to these.
  • the intended drive should have a high switching speed and a high electrical efficiency.
  • the invention solves this problem in a simple manner in that the switch armature is non-positively connected to an electrical coil which is arranged in the force field with the same pole opposite permanent magnet systems and experiences a deflection when electrical current flows through from one to the other magnet system.
  • the position of the switching point of the dial roller with respect to the path is insignificant, so that larger tolerances can be permitted.
  • you are designing the armature counter relay on it must pay attention to the switching point or the point of the greatest power output in the already short area just before the end stop, there is a relatively large way available in the magnetodynamic drive according to the invention, which is fully utilized due to the linear force distribution for advancing the counter can.
  • the geometry of the coil can also be adapted to the respective requirements.
  • the universal electrical adaptability of the coil to existing power sources represents a significant advantage.
  • the force that a current-carrying coil generates in the magnetic field depends solely on the induction (B) of the magnetic field in the air gap, the length of the conductor (1) or the number of turns and the current (I) flowing through the coil.
  • FIG. 1 shows the object according to the invention with a pivotably mounted switching armature and FIG. 2 with a switching armature designed as a slide.
  • the electromechanical counter designed according to the invention shown in FIG. 1 consists of several digit rolls 2, 3 sitting on a shaft 1, each of which has corresponding ones
  • Driving gears can be driven by the preceding numerical roller.
  • the initial digit roller 3 carries a gear wheel 4, in the tooth gaps alternately the tooth-shaped ends 5, 6 of a U-shaped switch armature 7, which is horizontal.
  • Axis 8 is pivotable, intervene. This alternating engagement of the tooth ends 5, 6 in the tooth gaps of the gear wheel 4 results in a step-by-step advance of the digit roller 3 in the direction of the arrow 9.
  • the switch armature 7 carries on the side facing away from the tooth ends 5, 6 on an arm 10 an electrical, wire-wound coil 11, which has the shape of a cylindrical disc on the outside and lies in a common plane with the axis 8.
  • the coil 11 is arranged in the magnetic field of two permanent magnets 12, 13 and, depending on the direction of the electrical current flowing through it, is either attracted or repelled by the magnet 12 or the magnet 13. This movement of the coil 11 in the magnetic field of the magnets 12, 13 is transmitted to the switch armature 7 for the purpose of advancing the digit rolls 2, 3.
  • the switching driving the gear wheel Anchor 15 is designed as a slide, on which the coil 11 is attached directly or via a non-positive mechanism. It is mounted with low friction in a corresponding guide and can be returned to the respective starting position by a spring 14 acting on it.
  • the coil 11 itself is in the effective air gap between two permanent magnets 12, 13 arranged with the same poles to one another. In principle, a single magnet would also be sufficient, but the efficiency increases many times over when using two magnet systems,
  • the required restoring force can also be obtained via a change in direction of the coil current instead of via a mechanical spring.
  • the counter can be advanced by the chronological sequence of a positive and negative pulse. It is not important whether the two pulses follow one another directly or act on the counter at any time interval. Because of these properties, a bistable mode of operation of the counter can also be achieved, the counter being incremented by a number irrespective of the direction of movement of the coil 11 if positive and negative pulses are present alternately for actuation. It follows that only a current direction inverse with respect to the current direction of the previous pulse can effect a counting process.
  • This operating mode can, for example, enable the evaluation of information from logic circuits and machine controls to be carried out more economically.
  • Operation of the counter according to the invention with alternating current can also be implemented, which appears to be particularly advantageous when the system is to be operated in the vicinity of its mechanical cut-off frequency.
  • a counter is available which is optimal for use in battery-powered devices such as Heat meters, as well as suitable for operation from solar batteries.
