Abstract

The invention relates to a method for determining and/or inspecting the content of coin rolls (1) which are wrapped in a preferably transparent packaging material (16). According to said method, optical recognition means (3) on the surface area of the cylinder (5) detect at least one line that extends across the entire length of the coin roll (1) and convert it to a signal. Said signal is supplied to an evaluation unit (8), in which evaluation unit (8) the signal is evaluated with respect to recurrent signal features and the number of periods of the signal features are determined and stored as the number of coins packaged in the coin roll (1). The evaluation unit (8) uses the stored number of coins to control means for displaying the number of coins (9) and/or a recording device (10). The invention also relates to a device for carrying out the inventive method.

Description

Method for determining and/or verifying the contents of coin rolls.
Field of the invention.
The invention relates to a method for determining and/or verifying the contents of coin rolls and to a device for carrying-out such a method.
Prior art.
Coin rolls wrapped with paper are known from the practice. Further is known from the practice a method for verifying the contents of a coin roll, wherein the coin roll is weighed on a weighing device, and wherein the detected weight is compared to a reference weight being specific for a coin roll of a certain coin type and de-nomination and for the number of contained coins. If weight and reference weight match, the coin roll is accepted. If however weight and reference weight do not match, the coin roll is sorted out and the coins contained therein are subjected to an inspection and/or counting process. It is disadvantageous in this method that by suitable selection of counterfeit coins or low-value disks, a reference weight can be adjusted rather precisely. A coin roll having at its opposite ends one coin each of correct denomination, therebetween however such counterfeit coins or disks, thus cannot be identified with the in so far known method.
From the documents DE 38 44 519 C2 and DE 38 44 777 C2, devices for producing coin rolls are known in the art, wherein the coin rolls thereby produced are wrapped with a transparent packing material. Such coin rolls may be subjected, in addition to the weight determination, to a visual test of the coin borders by a person, this is however very time-consuming and further very doubtful.
Technical object of the invention.
It is the technical object of the invention to provide a method for determining and/or verifying the contents of coin rolls, by means of which in a simple and reliable way the number of contained coins can be determined and if applicable in addition a test for validation can be performed.
Basics of the invention and preferred embodiments.
For achieving this technical object, the invention teaches a method for determining and/or verifying the contents of coin rolls preferably wrapped with transparent packing material, wherein means for optically detecting detect on the cylindrical envelope surface at least one line extending over the complete longitudinal extension of the coin roll and transform it into a signal, wherein the signal is fed to an evaluation unit, wherein in the evaluation unit the signal is evaluated with regard to periodically repeated signal features, and the number of the cycles of the signal features is deter-mined and stored as the number of coins wrapped in the coin roll, and wherein by the evaluation unit means for displaying the number of coins and/or a recording unit is controlled with the stored number of coins.
The invention is based on the finding that a signal generated by means of an optical sensor system contains periodic signal features based on the lining-up of the coin borders in a coin roll. The detected region of the cylindrical envelope surface is in the simplest case a line. It is however also possible to transform a partial area of the cylindrical envelope surface extending from a cylindrical base surface to the opposite cylindrical base surface into a signal. Here the above explanations apply in an analogous manner.
In an advantageous embodiment of the method, in the evaluation unit in addition at least one cycle can be compared to a reference cycle or different reference cycles for a certain coin type and one coin denomination or several coin denominations, in case of the cycle matching with a reference cycle, it and thus the coin type and/or the coin denomination can be assigned to the signal and stored. Herein, the fact is used that coins of different coin types and/or coin denominations have different coin borders, thus a detection or verification of the coins packed in the coin roll being made possible.
The measurement cycle (and consequently the reference cycle) can be measured for various signal features existing in the cycle. A signal feature may be the course of the intensity of reflected visible light. Another signal feature may be the received color, if applicable according to the light wavelengths irradiated on the coin roll. In this embodiment, it is therefore on the one hand possible to perform an automatic detection of the coin type and denomination (for this the evaluation of one cycle is sufficient), however on the other hand also to test each of the coins of the coin roll for correct coin type and denomination and if applicable to detect counterfeit coins or disks (then all cycles are evaluated and not only counted). Thus also an automatic coin roll detection in conjunction with a verification of the contained coins and thus detection of incorrect coin rolls is possible, for instance by that in the case of a cycle or several cycles not matching with a given ref-erence cycle or in the case of a cycle not'matching with other cycles of the signal, the evaluation unit generates an alarm signal.
The invention further relates to a device for determining and/or verifying the contents of coin rolls preferably wrapped with transparent packing material by means of a method according to the invention, comprising:
means for stably placing down a coin roll . to be tested, means for optically detecting disposed such that the optical detection angle covers at least a partial section of the cylindrical envelope surface, wherein the partial section continuously extends from one border to the opposite border of the coin roll, an evaluation unit connected to the means for optically detecting, and a display unit and/or recording unit connected to the evaluation unit.
The means for stably placing down a coin roll to be tested is in the simplest case a plane, horizontal surface, on which a coin roll placed down on the cylindrical envelope surface rests. It may be recommendable that a marking, for instance an outline, is applied on the surface, in order that the coin roll can be positioned with regard to the means for optically detecting and if applicable oriented with,regard to its longitudinal extension. It is however also possible to use a placing-down groove, where the coin roll is placed down. In this case it may be recommended to provide at least one marking in the groove or next to the groove, which determines the position of a cylindrical front face of the placed down coin roll. The means for placing down may however also be a human hand positioning the coin roll in the optical detection angle of the means for optically detecting.
The means for optically detecting may be selected from the group including "electronic optical or IR
camera, CCD sensor, scanner line, contact image sensor and barcode scanner". These components are well known to the man skilled in the art and do not require any further explanation.
In the evaluation unit, the signal of the means for optically detecting is received and processed. Processing basically comprises the detection of periodically repeated signal features, the number of cycles being the number of the coins in the coin roll. The number thus de-termined may be shown on the means for displaying the number of coins, for instance a numerical display.
Alternatively or additionally, the determined number of the coins may be fed to a recording unit, where then for instance a balancing of received coin rolls and a stock processing may be performed.
In the following, the invention will be explained in more detail with reference to figures representing examples of execution only. There are:
Fig. l: a diagrammatical representation of a device according to the invention, Fig. 2: a first variant of the invention, Fig. 3: a second variant of the invention, Fig. 4: a third variant of the invention, Fig. 5: a fourth variant of the invention, Fig. 6: a diagrammatic representation of a signal curve, and Fig. 7: a diagrammatic representation of a signal feature.
In Fig. 1 can firstly be seen means for stably placing down a coin roll 1 to be tested, for instance a placing-down surface 2. There a coin roll 1 is placed down. Above the placing-down surface 2 with the coin roll 1 thereon are arranged means for optically detecting 3, and that such that the optical detection angle 4 covers at least a partial section of the cylindrical envelope surface 5 of the coin roll 1, wherein the partial section continuously extends from one border 6 to the opposite border 7 of the coin roll 1. An evaluation unit 8 is con-nected to the means for optically detecting 3, and electrical signals of the latter are fed to said evaluation unit. A display unit 9 and a recording unit 10 are connected to the evaluation unit 8.
In Figs. 2 to 5 are shown various optical detection systems. Fig. 2 shows an electronic camera 11, the signal of which is fed to the evaluation unit 8 including a processor. There is made a digital picture recogni-tion/processing, whereby at least the number of coin borders and consequently the number of coins is detected.
Fig. 3 shows a variant, wherein the coin roll 1 is placed down on a transparent placing-down surface 2 (for instance made of plastic or glass), here also comprising a groove 12. On the side of the placing-down surface opposite to the coin roll l, a scanner line 13 is disposed, by means of which the coin roll is scanned. For this purpose, the scanner line 13 is controlled in a way known to the man skilled in the art. Thereby is generated a line picture of the coin roll 1, from which by means of conventional picture recognition and evaluation software the number of coins can be determined. It is however also possible that the scanner line 13 is moved to and fro _ 7 _ beneath the coin roll 1 and in the direction at right angles to the longitudinal extension of the scanner line 13, thus a two-dimensional picture being obtained. This in addition permits the recognition of border stampings of the coins. Further, in addition the color of the coin borders can be evaluated, thereby beside counting, a test for authenticity with high reliabilit y being made possible. Analogous considerations apply for the variant of Fig. 2.
In Fig. 4 is shown a particularly simple variant, namely with a barcode scanner 14. This is a manual device. An operator can hold a coin roll 1 with one hand and operate the barcode scanner 14 in a conventional manner with the other hand. In addition to the number of coins, further their border stampings or inscriptions can be detected.
In the variant of Fig. 5 a heat-camera picture 17 is recorded and evaluated by means of a heat camera 15.
Differing from the above variants, a determination of the number of coins can be made by determining the total length of the coin roll 1 only. With sufficient sensitivity or contrast capability of the heat camera, the periodically repeated signal features can however also be obtained by the heat-camera picture 17, which are further processed as described above. It may be recommendable that the placing-down surface' 2 is tempered above or below the ambient temperature, in order that a sufficient heat contrast is achieved.
In all shown cases, the coin roll 1 is wrapped with a transparent foil 16.
The respective means for optically detecting 3 are controlled in a way known to the man skilled in the art.

g The man skilled in the art is further familiar with the usual algorithms for picture detection and evaluation, which can easily be adapted to the method according to the invention.
In Fig. 6, an analogous signal is diagrammatically shown, which in the case of smooth coin borders is obtained by means of a scanner line 13. The ordinate is the signal intensity, here shown as a voltage. The abscissa is the travel coordinate along the longitudinal extension of the scanner line 13 (shown as a continuous line, in reality there are discrete values). Periodically repeated signal features can be seen, here plateaus 18.
The number of cycles or plateaus 18 corresponds to the coins present in the coin roll 1. The number of plateaus can for instance easily be calculated in a conventional manner after transformation of the voltage into digital voltage values. The flanks 19 and 20 correspond to the borders 6 and 7 of the coin roll 1. In Fig. 7, there is in detail shown a section of a plateau 18, for a coin having a border stamping. The plateau 18 has a detail structure being specific for a certain border stamping.
If this detail structure is compared to a given reference period, the evaluation unit 8 can determine by this comparison, whether the coin detected by the plateau 18 is a type or value corresponding to the assigned reference period. This may take place for one plateau 18 only. Then this serves for detecting the values of the coins in the coin roll 1. However, this may also take place for all plateaus 18. Then this serves for inspecting the coin roll 1 for any coins not identical to the other coins of the coin roll 1.
The invention may be used in the most various fields.
A first field is a "stand-alone" application, for instance at money transfer points, such as bank counters or the like. Then an operator can check received as well as handed-out coins rolls. A second field is the supervision of packing processes, such as in the prior art mentioned initially. Then a device according to the invention is provided in a packaging machine, and the packing step is performed thereafter. A third field is the automatic delivery and/or acceptance in money acceptance or money delivery and/or money change machines. Here, an automatic verification of received and/or handed-out coin rolls is performed. The recording unit is then integrated in the conventional control system of the automatic device.
