Abstract

The invention relates to a mechanical coin-testing device comprising a coin channel with a lower runner, upon which a coin to be tested rolls and an upper runner that contains a recess and supports the coin as it rolls. A magnet assembly is provided in said coin channel, in the vicinity of the recess in the upper runner. The magnet assembly is adapted to a permissible coin in such a way that the latter is guided past the recess, without falling into the open space formed between the upper and lower runner or being retained by the magnetic force of the magnet assembly. A rotatable locking lever, mounted behind the magnet assembly in the direction of travel, can be pivoted into the path of the coin to be tested. A magnet is located on said lever in such a way that the latter does not pivot into the coin channel when a permissible coin approaches, but pivots into said channel when an unpermissible coin approaches, said coin being more magnetic than a permissible one.

Description

Mechanical coin validator

The invention relates to a mechanical coin testing device according to the preamble of the main claim.

A large number of mechanical coin validators are known in the prior art which have a sensor arrangement in the area of their coin run channel which adjoins the coin insertion, which checks the authenticity and admissibility of the coin. The sensors check the dimensions of the coin, for example, and if the mechanical dimensions of the coin to be checked are the same, they must be distinguished by their metallic properties. There are two metal properties that can be recognized in a mechanical coin validator. The first property is the density or weight of the material from which the coin is made. Mechanical coin validators are therefore known which, in addition to the external dimensions, check a coin for its weight. Because this exam mechanically carried out, the "scale" must be designed as a highly sensitive mechanism, which can easily be put out of operation due to contamination or the like. Therefore, the second metal property, namely the magnetic or non-magnetic property of the material, is frequently checked.

To check the dimensions of the coin, i.e. of the diameter of the coin is provided in the coin run channel above the lower running rail of an upper running rail extending in the running direction of the coin, on which the coin to be tested is supported with its upper edge when it is unrolled. At a point on the running rail before the coin enters the acknowledgment area, a recess is provided in the upper running rail in such a way that the distance between the lower running rail and the upper running rail in the region of the recess is greater than the diameter of the permissible coin. So that a permissible coin, the magnetic properties of which are known, does not tip over through the free space between the lower and upper running rails, a magnet system is arranged in the area of the recess in the upper running rail, which preferably consists of one or more round bar magnets, the distance from which to Checking coin is adjustable and which are also adjustable in the horizontal and vertical directions. This magnet system is adapted to the magnetic properties of the permissible coin in such a way that the magnetic forces acting on the coin allow the coin to "float" through the magnetic space without tipping over into the area of the recess and thus reaching the acknowledgment area.

a prohibited coin caught by the magnet system can be prevented in the acknowledgment area.

This object is achieved by the characterizing features of the main claim in conjunction with the features of the preamble.

Characterized in that in the direction of the coin behind the magnet assembly, a pivotable locking device in the form of a rotatably mounted locking lever can be pivoted into the path of the coin to be checked, on which a magnet is arranged such that the locking device due to the coordination of the magnetic force of the magnet arrangement and the magnet on the locking device and the magnetic properties of the permissible coin with each other when approaching a permissible coin, does not pivot into the coin run channel and / or it has already rolled so far that the locking device is prevented from pivoting in, while the locking device pivots when approaching an inadmissible coin, a refined examination option is provided. The magnetic field of the magnet arrangement is, so to speak, "passed on" to the magnetic field of the magnet via the magnetic or partially magnetic coin, the polarities of the magnet having to be taken into account.

Partially magnetic, in particular so-called "bicolor" coins, such as some euro coins can be safely recognized.

In particular, manipulation from the outside, which is that a coin held by the magnet arrangement with a cardboard strip, a wire or another tool or a plurality of After this, if the inadmissible coins or disks are thrown out of the sphere of influence of the magnet system, an acknowledgment is no longer possible due to the blocking lever.

Advantageous further developments and improvements are possible through the measures specified in the subclaims.

would last. Of course, only one magnet, but also a large number, can be provided.

In the running direction 3 of the coin behind the magnet system with the round bar magnets 6, a locking lever 8 is pivotally mounted laterally next to the coin run channel via a pivot point 7 arranged on a fixed part of the coin validator, the lateral arrangement next to the coin run channel being shown in FIG. 1c. The locking lever 8 has a locking arm 9 which projects laterally and which can have an angle piece 9a angled at 90 ° at its end. The position of the locking arm 9 can be different, it can be arranged in the middle or be moved forwards or backwards.

When the locking lever 8 is pivoted about the axis of rotation 7, the locking arm engages in the coin channel, i.e. in the path of the coin in direction 3. According to Figure 1, the locking lever 8 is further provided in the upper area with an angle projection 10 to or in which a small magnet 11 is attached. In the illustrated embodiment, the north-south direction of the magnet is approximately perpendicular to the surface of the coin, it being noted here that the polarity of the round bar magnets 6 and the polarity of the magnet 11 are opposite.

If a permissible coin 2 is thrown into the coin validator in the exemplary embodiment, it is held "floating" on the rail along the running rail 1 and in the region of the ejection opening by the round bar magnets 6, the locking lever 8 being moved by the arrow 12 gravity indicated in Figure lc remains in the rest position, since the outer ring 2b, which is first in the area of influence of the magnet 11 arrives, is not magnetic. When the magnetic core 2a or the magnetic field of the round magnets begins to interact with the magnetic field of the magnet 11 via the magnetic core 2a, the coin has already partially passed the locking lever in the direction of the acknowledgment area, so that the lever 8 is prevented from pivoting by the coin 2 becomes.

The permissible coin 2 passes the locking lever 8 and arrives in the subsequent acknowledgment area, in which it is registered by appropriate sensors.

Of course, a coin made of only one magnetic material can also be checked, but then a more precise coordination between the magnetic force of the round magnets 6 and the small magnet 11 and the magnetic properties of the permissible coin and their spacing from one another is necessary. The magnetic force of the round magnet must not be so strong that the coin sticks and the magnetic field between the approaching coin and the small magnet must not be sufficient to pull the locking lever 8 when the permissible coin 2 approaches the path of the coin. Only when the coin is partially past the locking lever 8 may the lever 8 react, but it cannot pivot, since the coin blocks the pivoting path.

FIG. 2 shows a representation corresponding to FIG. 1, a coin 13 which is not permissible in the coin to be tested and is more magnetic than the permissible coin 2. When the coin 13 approaches the locking lever 8, the magnet 11 reacts with that the round bar magnet 6 strongly magnetized coin 13 and the locking lever pivots accordingly Z cQ P.

strips 15 are conveyed into the return channel.

The material of the locking lever is preferably plastic, as a result of which the mass, which is less than that of metal, enables faster acceleration and thus a shorter reaction time.

The arrangement according to the invention is also suitable for coin validators which only differentiate between magnetic, non-permissible, positive and non-magnetic or weakly magnetic permissible coins and which have no recess 5 in the region of the running rail 4. In this case, the locking lever is used to prevent the sticking of coins stuck to the round magnets.
