Description

Electronic coin validator.

The invention relates to an electronic coin validator.

The well-known electronic coin validators all use an all-round closed channel for coins, on which - on different Way - measuring probes are attached.

Either these runner channels aren't in any way at all TO open (and therefore difficult to clean) or they can be closed by means of a hinge or the like.

All of these constructions have naoh parts, especially with regard to the Accessibility in case of coin blockages.

The "hinge construction" also has disadvantages, if on everyone of the halves that are to be unfolded are seated who measure an exact amount among each other Must have reference.

Incorrect settings cannot then be avoided. Goose off from the fact that such constructions - if they have to work precisely - are relatively expensive. are.

The object of the invention is to provide a simple, inexpensive to manufacture To propose coin validators, which is easily accessible, which coin blockterwigen largely not allowed at all and which one in the case of a backing through Foreign bodies can be cleaned from the outside in the simplest possible way.

A further aim of the invention is that which is as suitable for production as possible. Execution from the point of view of lowest manufacturing costs.

According to the invention, therefore, the coin validator "channel" is not in Porm of a closed channel formed, but at least partially "open".

It consists in the # simplest and most perfect execution at the same time from a plate, which is inclined in the longitudinal and transverse directions and one on the Board arranged running floor of about coin thickness. One brought to the floor The coin will then roll down the inclined plane in constant contact with the plate.

This simple arrangement achieves that blockages by several Coins or blockages caused by bent coins or foreign objects are not at all All of these objects lose their place on the narrow catwalk (Floor) and fall down from it and into a return channel.

You can support this effect by adding actuatable elements attaches which - for example. Through the board passing through - any objects able to repel from the running edge.

In this connection idea of building a channel for coins from a blank inclined on both sides and a narrow catwalk associated with it, nothing changes if, for example, instead of the push-off elements, the running floor itself is designed to be movable and it bEfb ' Arranges actuation movable away from the board. In this case, too, some objects will lose their hold and fall into a shaft, only in a special way. this is advantageously the return shaft; In special cases, the "throw-off effect" can also be used to accept coins.

According to one idea of the invention, such a coin will be checked With particular advantage eo design that everything to be arranged along a coin track Elements for measuring and sorting the coins in a channel or a track which consists of a straight piece.

Of course, the idea of the invention does not change if you use the Total length of the coin path broken down into several zigzag-like sections.

The push-off elements or those designed to be movable away from the track The bottom of the track can either be actuated directly from the outside in a known manner design or train controllable.

With a coin operated telephone, it is particularly advantageous to use the Make use of the movement of the earpiece fork in order to unlock the device which is designed according to the invention To effect coin validator.

Changes to the "open" design of a coin career according to the invention In principle, nothing happens if probes are attached on both sides of the coin track Need to become. In this case the one to be attached on the "open" side will be used Fasten the probe using a suitable probe carrier, which in turn is preferably is attached above the coin track.

According to the invention, the probe with its probe carrier is only unconditional Cover the necessary area of the coin runway laterally and the remaining area will be the clear one The distance between the coin sliding surface and the inside of the probe must be so large that also In the area of a probe, a coin can be repelled from the lower projection can and falls down without jamming.

It is also possible, in an even more advantageous manner, to arrange both approximately opposite one another Probes of a measuring point on a common U-shaped support or in its legs arrange and then aieses U-piece - e.g. from above and vzw, in suitable guide and Locking elements - the raceway, "attach".

If several such pairs of probes are required on one track, can you arrange them on a common carrier.

You can proceed in the same way if several career paths, e.g. run parallel next to each other or parallel on top of each other: here, too, a common Carrier for all probes simplify the construction and the adjustment security raise.

It was avoided that a particularly advantageous embodiment of the inventive tester is that bad coins and foreign bodies be repelled by the running edge. In such everything becomes after one more thought the Invention at the end of the coin track an element arranged which is designed so that in the basic position there are running coins to the side of the running edge steers away. After actuation in the known manner, however, it will clear the way for the coin into an acceptance channel. This is also shown in the following example.

The previously mentioned board, which is the side wall on which the Coin runs along in constant support, can according to a further idea of the invention all elements required for the function of the auditor, or at least one Have part of it, so that the coin validator apart from the casing parts is essentially formed from this one plate.

It is more advantageous if you ask for another suggestion This invention simply uses a printed circuit board as a circuit board Suitable material selection - e.g. glass fiber reinforced polyester resin as the base material - You can get an extremely abrasion-resistant slide for coins in the cheapest way and electronic components can be installed on the free parts of this circuit board and apply the Leituhgen connecting them as a printed circuit.

Another idea of the invention then consequently proposes these printed conductor tracks to bring them together at a certain point, as far as they are needed for the external connections, and then to arrange a plug there or to design the circuit board itself as a direct plug in a suitable form. It is particularly advantageous to have part of the circuit board protrude in order to plug in a corresponding plug or to make the coin validator itself pluggable as a whole unit.

The figures explain the ideas of the invention and show: Fig.1 and 2: cross-sections through "open runner channels", FIG. 3 top view of an inventive concept Arrangement with coin gate at the end of the track, Fig. 4 side view of a board, which is designed as a printed circuit and all functional elements of a coin validator contains.

In Fig. 1, 1 denotes a plate and 2 denotes a plate pivoting about the axis 3 rail-like bottom of the coin track. A coin 4 is from a pair of probes 5/6 supervised. Probe 5 sits on the back of the circuit board 1, probe 6 on the opposite side Probe carrier 60 arranged above the coin track.

Fig. 2 shows a similar example. One for probes 6 and 5 in common The provided probe carrier 60 is designed in such a way that it can be plugged into the circuit board 1 is to be arranged. The probes are in his thighs. The coin 4 rolls over the bottom 2 of the track, which is arranged laterally or horizontally displaceable is dead when shifted to the side, it assumes position 20 and thus objects the omission at the bottom allowed.

In both cases is the distance of one probe from the coin track so large that a coin that has been pushed away from the outer edge falls freely downwards can and under no circumstances between the edge of the base and the inner edge of the probe carrier can clamp.

Fig.3 also shows the clip-on probe carriers and at the end of the from inclined wall 1 and with this inclined bottom 2 running track the whipstock 3, which in any case deflects incoming coins from the track. Only when a coin is tied well does it take off and leave a coin in channel 5 for get good coins.

Figure 4 shows a circuit board made of glass fiber reinforced polyester resin (1), which is designed as a printed circuit and supports the electronic elements like a coin career at the same time.

2 denotes an applied bar which is the bottom of the coin track 3 is the beginning of the raceway, 52 one from the gripping end 61 of a locking lever 60 stopped coin. The locking lever 60 is part of the magnet 6. Another Coin 51 is just in the measuring point, the one from the probe 5 on its carrier 4 and a second probe to be thought on the back of the board is formed. 40 denotes a fastening cover for the special carrier, 7 denotes the one shown in Fig.3 Deflection wedge. For the sake of simplicity, a cover wall is omitted, which with the Bottom 2 is homogeneously connected and which the entire board below the coin track covers. This is necessary to protect the conductor tracks and those on the circuit board arranged elements, for which only the Blook 8 is drawn here as a representative is. The wedge 7 is actuated by a magnet which is not shown and which is held with the screws 70 and 71.

With 9 and 10 formed as a plug protrusions of the board designated. Plug 9 is used to attach measuring or setting instruments, plugs lo the supply.

The connector tongues 91 to 95 designed as conductor tracks are only indicated. The lines going out from the connector tongues lol to 1o6 are also only partially drawn. A conductor run 401 leads from tongue lol to the supply of the Circuit 8, a branch 201 for supplying the magnet for the wedge 7 and a Another branch for the supply for the Srerr magnets ó (301).

Circuit 202 also supplies block 8. Via circuit tracks 205 and 206 signals go outside. 501 and 6o1 are the response lines for the two magnets.

8 with a longitudinal slot parallel to the bottom of the coin track is referred to, through which a bar 80 step and possibly

Objects on the floor of the coin track (coins and Foreign bodies) to the side and thus repel them.

The side view of the board shows very clearly that it is already represents a complete coin validator. You just have to tilt this board Put it in a shell-like housing and then already has the complete coin validator. All functional elements and all conductor tracks are arranged on the board. the entire unit can already be plugged in.

With the described execution, the points of view consider the most economical production in an optimal way.
