Definitions

  • the invention relates to a detection device according to the preamble of claim 1.
  • Such a detection device is known from the contribution by H. Effenberger "Microprocessor-controlled radio clock with analog display” in the book “Radio clocks”, edited by W. Hilberg (there page 105). There it is intended to install a reflection light barrier in the dial of the clock so that both the hour hand and the minute hand lead to shadowing of the optronic pickup system and thus to signal triggering when the installation location is covered; with which it is detected that one of these pointers has just turned into this structurally predetermined angular position.
  • a disadvantage of such a detection device is that both the hour hand and the minute hand must be able to be rotated independently of one another, that is to say they must be driven either via separate stepper motors or via a changeover gear.
  • Another disadvantage of the known detection device is that, due to the influence of scattered light, an accurate and reproducible angular signal transmission when one touches that optronic sensor is hardly feasible; whereby different pointer widths at different signaling times and broken pointers, as in the case of style clock pointers, even lead to multiple signaling and thus to false evaluations, which at most are particularly elaborate electronic correction means can be compensated in order to ensure the high display accuracy expected by the consumer from a radio clock.
  • the invention has for its object to provide a generic detection device such that the purpose of a clock, especially a radio clock, is not impaired in terms of its design training that sensors must be installed at visually detrimental locations and / or that There are restrictions regarding the design of the pointers; at the same time the functional reliability of such a device is to be improved.
  • This object is essentially achieved in that the generic detection device is designed according to the characterizing part of claim 1; where the term light barrier is also intended to include the function in the radiation spectrum beyond visible light.
  • the optronic hand position query is moved to the inside of the movement, there are no longer any restrictions regarding the design of the dial and the hands of the watch.
  • the movement including its pointer position detection device, has a compact and fully functional structure, which means that it can also be functionally tested without being installed in a watch.
  • the width and other design of the hands e.g. the query of the minute wheel including its intermediate wheel and the hour wheel, in the case of a stepper motor for driving the minute wheel with a geared hour wheel, minute-by-minute pointer position information every twelve hours.
  • the query of the second wheel including its intermediate wheel results in minute-precise pointer position information every minute.
  • the coupling of this information via an electrical circuit thus triggers a pointer position detection signal in a position defined precisely to the second, not only of the second hand, but also of the minute hand and the hour hand driven by it.
  • the subsequent pointer movement can be coupled by simply counting the index pulse from this detection position.
  • This also applies analogously to other geared display devices such as number rollers (instead of pointers before scaling).
  • Fig. 1 / Fig. 2 outlined clockwork 1
  • the rotor 4 of the second hand stepper motor 2 drives the second wheel 8 by means of a pinion 5 via an idler gear 6 and its pinion 7, and thus via the second hand shaft 9 which is rigidly connected to it, the second hand rotating in front of the minute track of a dial 10 (in the drawing not shown).
  • the rotor 11 of the second motor 3 drives the minute wheel 15 via its pinion 12, a further small-bottomed or intermediate wheel 13 and its pinion 14, with which the minute hand hollow shaft 16 is in rotary connection via a friction connection 17.
  • the hour wheel 21 is driven via a pinion 18, a change gear 19 and its pinion 20, which is rotatably connected to a hollow shaft 22 for the hour hand (not shown in the drawing).
  • the rotors 4, 11 and the intermediate wheels 6, 13 are held or supported on a small-bottom plate or carrier plate 23, on which a sleeve bearing 24 is also formed for the second hand shaft 9 projecting centrally through the hollow shafts 16, 22.
  • the dial 10 is arranged in front of the outer surface of the housing front wall 25; on its inner surface a bearing pin 26 for the change gear 19 is arranged, integrally formed in the illustrated embodiment.
  • a printed circuit board 26 serves to limit the axial movement, in particular of the seconds wheel shaft 9 (and via the seconds wheel 8 also of the intermediate wheels 6 and 13) to the rear, that is, away from the housing front wall 25.
  • a certain angular position of the hands in front of the minute track of the dial 10 corresponds to a certain rotational position of the wheels of the work 1 which are coupled to the hands by gears.
  • At least one light barrier 31, 32 is provided on the work 1 for detecting the entry of the rotational angle into this position.
  • it is preferably not a reflex light barrier 31, 32; instead, a radiation transmitter 33 is assigned to a radiation receiver 34.
  • the beam path of the respective light barrier 31, 32 is interrupted by the protruding wheels 6, 8 or 13, 15, 21, unless diaphragm openings 35 formed in these wheels are just aligned with one another (axially with respect to the orientation of the light barriers 31, 32).
  • the diameters of the apertures 35 in the fastest running of the wheels of the plant 1 engaging in the light barriers 31, 32, here the intermediate wheels 6 and 13, respectively, are chosen to be shorter than the arc piece 36 which the respective intermediate wheel 6 and 13, respectively Advancement through its stepper motor rotor 4 or 11 covered.
  • the apertures 35 in the intermediate wheel 13, in the minute wheel 15 and in the hour wheel 21 are just once every twelve hours due to their gear couplings; Once every twelve hours, the beam path of the light barrier 32 is transparent and therefore the receiver 34 is optically controlled for the minute-by-minute delivery of an electrical signal.
  • the gear constellation results in the stepping motor 2 provided for driving the second wheel 8, that the light barrier 31 switches through the aperture openings 35, in the second 8 and in its intermediate wheel 6 optically once every minute; From the receiver 34 of the light barrier 31 an impulse is given every minute.
  • the electrical interconnection of the output signals of the receivers 34 results in signaling that starts every twelve hours as electrical information that the minute hand (and the gear coupling in the factory 1 therefore also the hour hand) currently occupies one and only a very specific (reference or detection) angular position, which is structurally determined by the arrangement of the diaphragm openings 35.
  • stepper motor 2 only the stepper motor 2 is provided for driving the second wheel 8 via the intermediate wheel 6.
  • the minute wheel 15 is driven from a second wheel pinion 38 via the small-bottom or intermediate wheel 13 '.
  • the embodiment according to FIG. 5 represents a constructive simplification compared to the comparable embodiment according to FIG. 1, since it is no longer necessary to have a complete transmitter-receiver pairing per stepper motor 2, 3, that is to say per light barrier 31, 32 is and beyond the need for the electrical connection (ie the wiring) of electrical functional components away from the circuit board 37 is now eliminated.
  • ß for several light barriers 31, 32 now only a common radiation transmitter 33 is provided, which, like the individual light barriers 31, 32 assigned to radiation receivers 34, is arranged on the printed circuit board 37, that is to say mechanically and electrically connected; wherein the optical radiation energy is guided via radiation guide body 41 adapted to the transmitter-side radiation spectrum with regard to its material (for example acrylic glass for radiation in the range of visible light or germanium for radiation in the far infrared range) from the common transmitter 33 to the respective irradiation position 42 of the light barriers 31, 32.
  • its material for example acrylic glass for radiation in the range of visible light or germanium for radiation in the far infrared range
  • the realization of the radiation guiding bodies 41 by means of machined or non-cutting geometrical structures, which are dimensioned to adapt to the spatial conditions in the clockwork 1 and can thus already be dimensionally assembled during the construction of the clockwork 1, is cheaper than the use of flexible fibers. especially since such rigid bodies can be realized in a manner known from floodlight deflection technology by means of reflection bevels 43 narrower radii than with curved guide fibers, and the mechanical fixing does not have to be realized with a radiation exit surface, but is located at a structurally more favorable location of the rigid guide body 41 can be.
  • two guide bodies 41 begin in front of the transmitter 33, in order then to branch out in accordance with the spatial conditions.
  • the two rigid guide bodies 41 are held on the carrier plate 23 which is decisive for the positioning of the gear train, ie the diaphragm openings 35.
  • the illustrated guide body 41 runs from a plane lying behind the plane of the drawing via a bend 44 into the plane of the drawing and via a further bend 44 into a recess 45 on the inside of the housing front wall 25, where after a last bend 44 with a radiation exit surface in the irradiation position 42 to the light barrier 32 ends.
  • the other guide body 41 runs along the carrier plate 23 behind the drawing plane in order to enter the drawing plane in the area of a recess 43 in the carrier plate 23 and end here with a radiation exit surface in the irradiation position 42 for the other light barrier 31.
  • the simplified manufacturing and installation options in particular with regard to the arrangement of electrical components exclusively in the printed circuit board 37, also result in greater functional reliability in addition to simplifying assembly; which is increased by the rigid guide body 41 and by better shielding against external radiation.
  • a reduction in the axial overall height can be achieved in the solution according to FIG. 5 compared to a solution according to FIG. 1, because the axial overall height of the transmitters 33 and the receivers 34 is now not staggered one behind the other, but also irradiation positions with the radiation exit surface of the guide bodies 41 42 can be operated in more crowded and difficult to access positions.
  • the light barriers 31, 32, 39 preferably operate in the infrared radiation spectrum, because the transmitters 33 in the form of radiation-emitting diodes have very small dimensions and can be operated with a voltage of less than 1.5 volts, ie like a battery-operated clockwork, from a single cell.
  • the receiver 34 which is tuned to an infrared radiation spectrum, makes complex optical shielding measures against extraneous light influences from the surroundings of the plant 1 superfluous, so that the construction of the light barriers 31, 32 and 39 within the practically closed housing of the plant 1 is already one for the needs in practice usually results in adequate shielding.
  • the pointers moved by the associated stepper motor 2 or 3 are in a defined position. If the components 29 are designed in terms of circuitry in such a way that from now on the further switching of this pointer is also coupled by counting the assigned stepper motor control pulses, there is always electrical information about the current pointer angular position with respect to the reference position in which the diaphragm openings 35 are aligned with one another.
