Definitions

  • the invention relates to a roller counter according to the preamble of claim 1.
  • Roller counters are used in counting devices, for example in electricity meters. They have number rolls that bear the numbers 1 to 9 in successive angular positions and are lined up side by side on a number roll axis. The counting result is given by a combination of one digit of each number roll, which are at the same height of each number roll and which usually appear within an aperture.
  • the numerical roller for the lowest digit carries a sprocket with a lower pitch, by means of which it is driven more or less quickly according to the value of the size to be displayed, those for higher digits with a sprocket with which the tens transmissions are effected.
  • the tens transfer is carried out by a driving device on the number roller for the low number of digits via a switching roller on the ring gear of the number roller with a higher number of digits.
  • the indexing rollers sit on an indexing roller axis, which is generally parallel to the number roller axis. Both the number rollers and the shift rollers are mounted on their respective axes in such a way that they only have a very small amount of play in the lateral direction during normal operation, so that the tens transfer can be carried out without interference.
  • This coupling of the number roller and the switching roller-number roller means that the number rollers cannot be set to zero or to a predetermined position in the operating position.
  • one of the two axes is at the ends of a known roller counter guided in elongated holes, which are directed so that the number rollers are decoupled from the switching rollers when these axes are brought to the ends of the elongated holes opposite the operating position. It is achieved by suitable, usually resilient elements that, just as in the operating position, the axis assumes a stable position in the decoupled position (DE-PS 19 65 806; DE-PS 20 55 243; DE-GM 70 17 711). These solutions cannot completely prevent the relevant rollers from temporarily disconnecting when larger bumps occur, especially when the device is being transported, and there is therefore the possibility that incorrect positions of the number rollers occur on the device.
  • the invention has for its object to provide an easy to manufacture device for decoupling number rollers and switching rollers, which does not allow unwanted decoupling of roles.
  • FIG. 1 shows an example of a roller counter in Front view. It consists of a circuit board 1 in which a number roller axis 2 and a switching roller axis 3 are mounted at fixed points. On the number roller axis 2 there are number rollers 4, on the switching roller axis 3 switching rollers 5.
  • the roller counter is in the operating position, the number rollers 4 have very little play since so that the coupling between the number rollers 4 and the switching rollers 5 is retained.
  • This is effected by a lever arm 6, which is pivotable by means of an eye 7 with its bore in the switching roller axis 3, almost encompasses a gift de number roller axis 2 acting as a spacer 8 and is clamped to the circuit board 1 by means of a clip 9.
  • the gift serving as a spacer 8 is dimensioned in the direction of the number roller axis 2 so that the number rollers 4 cannot move to the side beyond their play. In particular, the number rollers 4 and the switching rollers 5 cannot be decoupled.
  • the number rolls 4 are shown here without a treadmill, which is used many times to protect the numbers on the number rolls 4 from scratching, but which noticeably widens the number rolls.
  • the lever arm 6 is shown in the side view.
  • the eye 7 is guided in the control roller axis 3, not shown here.
  • the fork acting as a spacer 8 has a depression 10 at the bottom which resiliently engages in the number roller axis 2, not shown here.
  • the clip 9 is drawn, which clamps the lever arm 6 to the circuit board 1 in the operating position.
  • the lever arm 6 carries an operating lever for easier operation.
  • FIG. 3 shows the roller counter shown in FIG. 1 in a position in which a number roller 4 denoted by 4 'is set to zero or to a predetermined position can.
  • the lever arm 6 is pivoted about the eye 7 held in the switching roller axis 3, the fork serving as a spacer 8 being removed from the number roller axis 3.
  • the number wheels 4 can now move laterally.
  • the number roller 4 'to be adjusted is moved laterally out of the coupling with the switching rollers 5 acting on it and set to the desired number.
  • the number rollers 4 and the switching rollers 5 should be dimensioned such that the number roller 4 can only be moved into the desired position with a small but noticeable resistance.
  • the other number rollers 4 can then be adjusted in the same way. If all number rollers 4 are set in the new position, the lever arm 6 is pivoted back into the operating position.
  • the number rollers 4 are now in the desired starting position for the subsequent counting and are fixed laterally, so they can no longer be adjusted unintentionally.
  • the spacer for coupling and decoupling the counting rollers 4 or the switching rollers 5 can also be designed in a different way, for example in the form of a rake, which comprises either the switching rollers 4 or the number rollers on one side and is supported by eyes on the other roller axis.
  • roller counter described requires little space, since there is no shifting of the axes, can easily be set to zero or another combination of numbers, is not moved out of the set combination of numbers even by large shocks, is easy to assemble and can can be manufactured inexpensively.
