Description

The present invention relates to coin and token machine and refers to a coin dispenser measurer at the exit of coins, tokens or the alike, from a container.
There are coin dispensers, known as hoppers, having a coin container and a disc element for withdrawing single coins from such container and for delivering such coins.
Some of these devices include also measuring means, of the diameter of the outgoing coins, including a motor for rotating the disc provided with encoder and a sector or windows disc associated to the disc rotational shaft for measuring the respectively speed and the angular position of the disc.
A disadvantage of these known devices consists in the fact that these devices are complex and expensive.
Another disadvantage of the known devices consists in the fact that they have casual and periodic errors of the speed evaluation and have uncertainty and errors in establishing the disc position with consequent excessive uncertainties in evaluating the coin diameter.
An object of the present invention is to propose a coin dispenser and a coin meter that is simple and inexpensive.
Another object is to propose a precise device and without excessive measuring uncertainties.
A further object is to propose a device with reliable function and easy and fast maintenance.
The characteristics of the invention are evidenced with particular reference to the enclosed drawings in which:

figure 1 shows a front and axonometric view of the coin dispenser and coin meter object of the present invention;
figure 2 shows an axonometric view of the dispenser of figure 1 in which some parts have been removed for better evidencing the others;
figure 3 shows a front view of the device portion of figure 2;
figure 4 shows a side view of one of the elements removed by figure 2;
figure 5 shows a side view of a prism means of figure 2;
figure 6 shows a side view of a rotating disc of figure 2;
figure 7 shows an axonometric view of the rotating disc of figure 2;
figures 8 and 9 show top and axonometric views of the prism means of figure 2 and figure 5.

With reference to figures 1-9, numeral 1 indicates the coin dispenser and coin meter object of the present invention. The device 1 first includes a rotating disc 2 associated and coaxial to a second rotating disc 26 and cooperating with this latter to transport the coins from a container 7 to an outlet 8.
The first rotating disc 2 has a parametric toothed wheel 28 engaged by a motorized pinion for rotating axially said first rotating disc 2 jointly to the second rotating disc 26.
In an operative condition, the two rotating discs are rotated around their sloping main axis and their lower portions are inside the coin container 7 and the outlet 8 is placed closed to their tops. The discs rotate axially in a respective flat and circular seat 3 carried out in a device body 4 with the first rotating disc in contact, or almost, with the flat surface of the seat 3. The first star-shaped rotating disc 2, with curved arms and inscribed in a perimetrical circle, is equipped with a plurality of coin housings 5 separated by shaped arms 6 each arranged to carry a coin from the container 7 to the outlet 8 and, in cooperation with teeth means 12, for expelling the coin through the outlet 8.
The second disc 26 has holes with shaped edges in order to favour the entry of the coins into the same holes. Every hole is opposed to a respective housing 5 of the first rotating disc so that each coin fall from the hole into the corresponding seat.
Moreover, the device includes two sensor means 9 placed in the seat 3 at a mutual predetermined distance and in data connection with a processor means of the device.
The device 1 is also equipped with a plurality of activation means 10 each fixed to a respective shaped arm 6 and arranged to transit over both sensor means 9, due to rotation of the discs, and to activate each sensors passing thereon.
In addition the device 1 includes a coin detecting means 11, placed at the outlet 8. The detecting means 11 is in data connection with the processor means and is activated by the coin exiting from the disc.
The two sensor means 9 and the detector means 11 are optical and their activation occurs when their optical circuit is closed or open.
Each sensor means 9 includes a respective light emitter means 20, for example a LED (Light Emitter Diode), and a respective and spaced light sensitive means 21, for example a photoresistor or a phototransistor with control circuit.
The light emitter means 20 and the light sensitive means 21 emit and receive the light in respective operative directions and such means 20, 21 are fixed with respect to the plane of the seat 3 so that each operative direction are almost perpendicular to the said plane.
The light emitter means 20 and the light detector means 21 are placed under the active end of the activation means 10 when it transits on the sensor means 9 having each light emitter means 20 and light sensitive means 21.
The activation means 10 is made of transparent material for the light emitted by the light emitter means 20 and is shaped elongated with prisms at its active ends for refracting the light of the emitter means 20 towards the light sensitive means 21 when this activation means 10 pass on the sensor means 9.
The light sensitive means 21 sends a signal to the processor means when it receives the light of the respective light emitter means 20 due to the transit of one of the activation means 10 or when the respective shaped arm 6 passes on such sensor means 9. In this way the two sensor means 9 send the respective signals at the transit instants of each shaped arm.
The detector means 11 includes a respective light source 22 and respective and spaced light receiver means 23 having the respective almost parallel operative directions and orthogonal to the outlet 8.
The light source means 22 and light receiver 23 are placed under, and spaced by, prismatic respective ends of a light transmitting means made of a material that is transparent to the light made by the light source means 22 to refract the light towards the known light receiver means 23 when none coin engages the outlet 8 and therefore when there is no obstructions to the light flow between one of the light source means 22 and light receiver 23 and the light transmitting means.
When a coin reaches the outlet 8 between the light source means 22 or the light receiver means 23 and one of the end of the light transmission means, this coin intercepts the light and said light receiver means 23 sends a signal to the processor means signalling the instant of the passage.
The device 1 includes a connecting means 24 reproducing the star shape of the first rotating disc 2. The end of each arm of the connecting means 24 has a respective activation means 10. The connecting means 24 is fixed and interposed between the rotating discs, first 2 and second 26, with each of the activation means 10 faced to a respective shaped arm 6.
The connection means 24 is fixed to the face of the first rotating disc 2 opposite to the seat 3 and each shaped arm 6 has two holes 25 for the passage of the light to the ends of the corresponding activation means 10.
In addition the device includes an optical coin detector 27 placed at the external end of the outlet 8 and fit to supply a reliable counting of the coins delivered by the device.
In operation condition, the coin detecting means 11 sends a signal to the process means when it detects a coin, each sensor means 9 sends a respective signal to the elaboration means when it detects an activation means 10 of the shaped arm 6 of this coin or an adjacent predetermined shaped arm 6, the process means counts the time elapsed between the signals supplied by the coin detecting means 11 and one of the sensor means 9 and the time elapsed between the signals supplied by the two sensor means 9 to calculate the diameter of the respective coin on the base of a special algorithm memorised in the same process means.
An advantage of the present invention is to supply a coin dispenser and coin meter that is either simple and cheap.
Other advantage is to supply a precise device without excessive measuring uncertainties.
A further advantage is to supply a device of reliable operation and of easy and fast maintenance.
