Definitions

  • the invention relates to a coin device according to the preamble of patent claim 1.
  • Coin units of the type mentioned are known in various embodiments. They have in common that several test sensors are arranged along a coin path, the coins on different criteria, such. As size, thickness, material, etc., examine.
  • an evaluation device which is usually formed by a microprocessor, the measurement signals of the sensors are compared with stored reference values.
  • An acceptance gate which is actuated by an electromagnet, is switched in accordance with the output signal of the evaluation device so that they forward coins to be accepted and steer unacceptable coins into a return channel.
  • Such devices are in the DE-A-35 22 229 and DE-A-24 44 950 described.
  • the acceptable coin passes directly into a cash register, with a presence sensor following the acceptance branch determining when the coin has passed the switch.
  • a coin sorting is followed by the acceptance switch, which directs the coins, depending on the value, into different stores (coin tubes) EP-A-0 470 587 ).
  • switches in the form of flaps or the like are also actuated by an electromagnet, which in turn are controlled by the microprocessor.
  • the invention has for its object to provide a coin meter, in which the path between a sensor for a coin and a sensor downstream of the switch can be minimized.
  • the evaluation device generates a bias signal for the electromagnet, which is prior to the generation of the control signal and is initiated by a signal of an upstream sensor.
  • the invention is based on the recognition that the magnetization can already be set in motion before the switch or damper is to perform a movement. If z. B. the last test sensor generates a measurement signal, this can be used to set the magnetization of the magnet for the acceptance path in motion, either directly or at a predetermined time interval to the occurrence of the measurement signal, this distance can be varied depending by size of a coin. It will be understood that a larger diameter coin is "faster" on the accept turnout than a smaller coin. Therefore, premagnetization should be done earlier with a coin of larger diameter than with a smaller coin.
  • the premagnetization of the acceptance-gate solenoid is independent of whether the microprocessor generates an accept or return signal. At the beginning of the bias is therefore still open whether the detected coin is accepted or rejected. It is therefore necessary to interrupt the magnetization process when the magnet is not to be operated. Therefore, the magnetization is interrupted when the evaluation device generates no control signal for the electromagnet. This control signal can not be generated until the above-described comparison between the measurement signals of the test sensors and the reference values has taken place.
  • the electromagnet is connected to DC voltage via an electronic switch and the bias signal of the evaluation device is placed on a PWM actuator, which actuates the switch.
  • a test sensor checks the diameter of the coins and the evaluator generates the timing of the bias signal in time as a function of the size of the diameter such that as the diameter increases, the premagnetizing signal starts earlier, and at a smaller diameter later.
  • the invention has the advantage that the path of the coin from a test sensor to the associated switch can be designed to be relatively short. Another advantage is that the magnet can be relatively small in size. It is understood that the distance to travel for the coin can be reduced depending on the size of the magnet. The more powerful a magnet, the faster it can respond and operate a turnout. For coin-operated devices, however, the goal is to design the electromagnets as small as possible, not only for reasons of cost, but also for reasons of space-saving.
  • a coin device 10 is shown in perspective, as it is known per se. It should not be described in detail in its structure. It can be seen a coin insertion slot 12, which is followed by an area in which the coin moves on a track (not shown) along sensors 14, which check a coin, which is shown at 16, for different properties. A last sensor in the running direction is designated CP2. After leaving the Münzlaufbahn the coin shown 16 is above a Münzweiche 18 in the form of a pivotable about a horizontal axis flap, which is actuated by an electromagnet 20. Depending on the operation of the accepting path 18, the coin passes into a receiving shaft 22 arranged vertically below or via a track into an adjacent return shaft 24.
  • Fig. 3 it is shown how the acceptance magnet 20 is actuated. It is connected to a DC voltage source 26 and is switched on or off with the aid of an electronic switch 28.
  • the electronic switch 28 is above a PWM actuator 30 (pulse width modulation), which in turn is controlled by a microprocessor CPU or 32.
  • the microprocessor 32 is also the evaluation device for the coin mechanism according to FIG. 1, which contains signals from the individual sensors 14, CP2 and from a presence sensor CP3, for example for controlling the acceptance magnets 20.
  • the microprocessor compares the measurement signals of the test probes with stored reference values and generates them for a coin to be accepted an acceptance signal and for an unaccepted coin a return signal. Accordingly, the acceptance switch 18 is actuated by the electromagnet 20.
  • the acceptance magnet 20 is activated when the microprocessor has performed the desired-actual value comparison and has generated a corresponding signal. In the present case, however, a bias signal is already generated when the coin 16 has passed the last check sensor CP2. The acceptance magnet 20 is already supplied with power, so that its bias can begin. If the coin 16 is found to be good due to the comparison in the microprocessor, the magnetization is continued until an actuation of the switch 18 takes place, so that the coin z. B. is directed into the receiving shaft 12. If, however, it is determined in the microprocessor that the coin is to be rejected, a return signal is generated, which then interrupts the magnetization of the acceptance magnet 20.
  • the process described is shown in more detail in FIG.
  • On the time axis (b) is shown in solid lines, the magnetization signal for the acceptance magnet 20 without bias. In dashed lines the impulse for the bias is shown.
  • On the time axis (c) the pulse of the presence sensor CP3 is shown.
  • On the time axis (d) the Vormagnetleiterszeitdauer is shown with rejected coin. It is labeled x. From the illustration it can be seen that with the generation of a signal from the last test sensor CP2 at the same time the magnetization of the acceptance magnet begins. After completion of the signal from CP2, the microprocessor compares the test signals with the reference values.
  • FIG. 3 yet another sensor 14.1 is shown, which measures the diameter of the coins.
  • the magnetization of the magnet 20 can be controlled. With a larger diameter, it is necessary to achieve a faster response of the acceptance switch than with a smaller diameter.
