Mechanical coin validator

The innovation relates to a mechanical coin validator with a permanent magnet assigned to a coin channel to influence the movement path of inserted coins in the direction of the ejection or acceptance chute and an ejection mechanism to remove any sticking to the permanent magnet Coin or magnetic metal disc in the direction of the ejector slot.

Such mechanical coin validators are known. They are based on the fact that the magnetic field of a permanent magnet makes the run The speed of the inserted coin is more or less influenced depending on the

and / or electrical
magnetic / properties of the coin alloy. By inserting a strongly magnetic coin or a magnetic disc, for example with fraudulent intent, it can happen that the magnetic coin or disc gets stuck on the permanent magnet and thus represents an obstacle for coins that are subsequently inserted. A precaution must be taken for such a case

7503383 19.06.7B

be taken to remove the stuck coin from the magnetic field, for example by pressing the money return button on the machine. It is known in this context to provide a stripping device which can be actuated by the return button, with the aid of which coins are stripped from the magnet and can be fed to the discharge chute

The innovation is based on the task of creating a mechanical coin validator in which magnetic disks or coins stuck on the permanent magnet are replaced by simple Means and with the greatest possible security to be freed from the magnet.

In a mechanical coin validator of the type mentioned, this object is achieved in that the permanent magnet of a holder is received, which can be pivoted away from the coin channel or towards this, and that the ejection mechanism an actuator engageable with the bracket.

The permanent magnet is not in the coin tester according to the innovation fixed as in the prior art, but listed pivotable. By operating the actuator, which is coupled, for example, to the money return button, the Permanent magnet can be pivoted into a position remote from the coin channel, so that the magnetic field so much reduced in the coin channel that the magnetic holding forces are no longer sufficient to keep the coin in the

7503383 06/19/75

Coin channel remains to be held. This way, with With absolute certainty, magnetic disks that have got stuck in the area of the magnetic field can be triggered.

In one embodiment of the innovation it is provided that the actuating member is displaceable parallel to the coin channel and the magnet holder has a ramp-like section, via which the actuating member swings the magnet holder running onto it, if the swiveling also can be realized in any suitable manner, this embodiment provides an advantageous actuating mechanism for the magnet holder.

In a further embodiment of the innovation it is provided that the actuating member is magnetic at least in one section and this magnetic section rests against the magnet when the magnet holder is pivoted out. The magnetic, am Magnet-adjacent section bundles the magnetic field lines to deflect them to the opposite pole, so that the magnetic field within the coin track is weakened even further by this measure.

The stuck discs or coins should if possible be directed into the ejection chute «In this context Another embodiment of the innovation provides that a drain lever is arranged on the coin channel, d © r when actuated of the actuator is swiveled into the coin channel and a coin freed from the permanent magnet into the Auawerf-

shaft directs »This drain lever can be used in an advantageous manner be coupled to the magnet holder in such a way that the drain lever is pivoted into the coin channel when the latter is released from it is moved.

An exemplary embodiment of the innovation will be described in more detail below with reference to drawings.

Fig. 1 shows a section through part of the coin validator _{according to the invention t} wherein the magnet holder is pivoted away from the coin track.

Fig. 2 shows the same section as Fig. 1, but the magnet holder is in the working position.

FIG. 3 shows a side view of the arrangement according to FIG. 2.

One Magnet holder, which holds a permanent magnet 17, has two bearing sections 18, 19 which are rotatable on the bearing pin

A plate-shaped actuating member 23 is arranged displaceably on the support plate 10 above the magnet holder 16. For this purpose, the actuating member 23 has two slots 2k and 25 (Fig. 3) through which pins with heads 26 attached to the support plate 10 are passed in order to allow only a longitudinal displacement of the actuation plate 23 parallel to the support plate 10 * At the lower left end If the actuating plate 23 has a flange 27 bent at right angles thereto, dex * is in engagement with one end of a tension spring 28. The other end of the tension spring 28 is fastened to a flange 29 which is bent out of the support plate 11. (The flange 29 is omitted in FIG. 1).

In the lower area, the actuating plate £ 3 has an actuating section bent out at an angle from the plane of the plate, the lower leg 31 of which runs approximately parallel to an inclined actuating surface 32 of a ramp section of the magnet holder 16, _{or the like}

On the bearing pin 15 is also a two-armed drain lever 34 pivotably mounted, the upper arm 35 of which is fork-shaped and the lower arm 36 of which is a lower one

At the upper end, the actuation plate 23 has an actuation flange which is bent at right angles and which can be actuated in the direction of the arrow Ή by a component (not shown) of an ejection mechanism.

During the normal state, the coin validator assumes the position shown in FIG kt exerted on the flange kO of the actuating plate 23, which is then shifted downward, whereby the actuating section 31 runs onto the ramp surface 32 and the magnet holder 16 is pivoted into the position shown in FIG. 1 about the axis of the actuating pin 15 magnetically conductive, so that the magnet 17 is practically "short-circuited" and thus generates a negligibly small magnetic field in the coin channel 11, which with absolute certainty is no longer sufficient to further fix the previously held coin so that it falls downwards. Due to the pivoted position of the magnet holder 16, the cam
