Definitions

  • the invention relates to coin selectors which are generally integrated in coin-operated apparatus or machines.
  • the parts of a given type are selected first by the maximum dimensional characteristics imposed by the slot for inserting the parts into the device.
  • the present invention relates to a new currency selector which can be qualified as multi-room in that it is of a design suitable for receiving and identifying various kinds of coins without modifying its structure and its coin characteristic sensors, and from which it suffices to compare measurement results with memorized identification data of the only parts which it is proposed to accept.
  • a new currency selector which can be qualified as multi-room in that it is of a design suitable for receiving and identifying various kinds of coins without modifying its structure and its coin characteristic sensors, and from which it suffices to compare measurement results with memorized identification data of the only parts which it is proposed to accept.
  • the invention also advantageously leads to a selector of simple intrinsic embodiment, of reduced bulk, and operating in a static position of the parts and according to a principle which gives it an advantageous reliability in this field.
  • the coin selector according to the invention in which the coins are brought into static position in the presence of at least one sensor for identifying a characteristic of each coin, is characterized in that '' it uses, for the purposes of identifying at least one dimensional characteristic of at least one type of part, a capacitive sensor in which the part in static position constitutes one of the plates of at least one capacitor, the capacity measurement is representative of the corresponding characteristic of each part to be identified.
  • such a selector comprises at least two different capacitive sensor plates disposed on either side of the static position for identifying the parts, one of the plates being of larger surface facing the part of larger diameter to be identified in order to evaluate the corresponding diameter characteristic of each part, the other plate being of smaller area than the part of smaller diameter to be identified in order to evaluate the thickness characteristic of each part.
  • an inductive sensor arranged inside the plate of the aforementioned capacitive sensor plate can easily be integrated, for the purpose of identifying an electromagnetic characteristic of the material of each part. surface, this inductive sensor having a front dimension smaller than that of the smallest diameter part to be identified.
  • the capacitive measurements can also be associated with such a selector, apart from the capacitive sensor (s), a control capacity for taring the measurements made, usable for compensating for variations in atmosphere likely to influence the result of said measurements.
  • the selector shown comprises two parallel plates 1 and 2 made of electrically non-conductive material, kept assembled together with a given spacing, by means of spacers 3, in which screws for holding the plates, not shown, are engaged.
  • the plate 1 is provided on its face opposite the other plate with a sidewalk 4 for circulation of the parts, such as the part P of FIG. 1, this sidewalk being essentially constituted in the form of an attached track and inclined with respect to the horizontal in order to bring any part introduced into the selector according to arrow E, to roll to a stopped position for identification against a barrier 5.
  • This barrier is provided movable transversely with respect to the plates and subjected to means for erasing and returning to the stopped position which may be any and here not shown. It should also be understood that each piece is brought into position on the sidewalk after having passed through a not shown guide slot of the device, of size at least equal to the largest dimensions of pieces of intended use.
  • the plates 1 and 2 are mounted with a certain inclination relative to the vertical,. so that any part brought to the sidewalk 4 bears laterally in a stable position against the plate 1 while descending the inclined slope of the sidewalk to its stopped position. In this latter position, the part rests on a sidewalk portion 4a formed in the form of an electrically conductive segment.
  • FIG. 2 shows in FIG. 2, by way of illustration, on the one hand in solid line an outline of a part Pm of maximum accepted diameter and, on the other hand in phantom, an outline of another part Pp of the minimum accepted diameter, both in their normal stop position against the barrier 5 which is their static identification position.
  • a conductive plate P1 is stuck shaped and arranged so as to be enveloping the largest part Pm in its static position, as seen in FIG. 2.
  • a conductive plate P2 On the internal face of the plate 2 is bonded a conductive plate P2 shaped and arranged so as to be in the envelope of the smallest part Pp in its static position, as seen in FIG. 2.
  • the plates P1 and P2 thus define, with any part P stopped in the static position, the two plates of two capacitive sensors, and they are respectively intended to be electrically connected to a capacity measurement circuit passing through the conductive segment 4a of the pavement and the piece P as the second plate of each capacitive sensor thus formed.
  • a selector makes it possible to obtain, by measuring the capacity between the plate P1 and the part P to identify a characteristic representative of the surface of the plate constituted by the part P considered, and which is therefore a function the diameter of the latter, taking into account the constant thickness of the plate 1 as a dielectric.
  • the measurement of the corresponding capacity constitutes a characteristic representative of the residual interval e existing between the part P considered and the plate P2, and that 'It is therefore a function of the thickness of the part to be identified.
  • an inductive sensor CI consists of a ferrite carcass 6 with an E-section flush with the plane of the internal face of the plate, and in which is housed a coil 7 intended to be connected to a circuit for measuring the inductance of this coil, which is a function of the closure of the magnetic circuit of the carcass 6 which the part P to be identified ensures in the predefined static position. This measurement is thus representative of an electromagnetic characteristic of the material of each part.
  • the insulating plates 1 and 2 can serve as a printed circuit support for the capacitive measurement circuits provided, an additional insulating plate 8 being here provided as a support for the inductive sensor CI and can carry a corresponding measurement circuit.
  • both the capacitive measurement circuits and that of the inductance measurement can be of any known or appropriate type for such measurements, at the choice of a person skilled in the art.
  • the barrier 5 can be temporarily erased to allow the tested part to continue towards an acceptance or refusal switch which can be actuated as a function of the exploitation of the measurement results.
  • the barrier 5 can be provided as an erasable barrier for the sole acceptance of the coins, while a part of the sidewalk 4 and the portion 4a thereof can be precise as elements which can be erased transversely to the plate 1, in order to fulfill the function of rejecting parts that are not accepted to a corresponding waste.
  • This or these erasing functions can be combined in a known manner with a sorting function leaving the pieces coming one by one to the identification station, and the measurement cycle can be triggered in response to any detection of the presence of parts provided in any known manner (by presence contact or photoelectric detection for example), being that all of these parts handling arrangements can receive many solutions or variants within the framework of the principles of identification of parts and construction of the selector which is particularly the subject of the present invention and which has just been described.
