COIN COUNTING DEVICE Filed April 15, 1965 2 Sheets-Sheet 2 7 4 gi t 70 8 I 5 7 I I :5 ZZZ}- T12? Fig.7 a
The invention relates, in particular, to a coin or money counting machine in which the coins are sorted and delivered by the sorting device into individual tubes in accordance with the coin denomination. Machines of this nature have heretofore operated in a mechanical manner, They usually employ a counting star which is arranged in a lateral recess of a coin passageway channel or chute. The coins have to pass the star one after the other. The counting stars are of a size comparable to the variety of coins which is counted and will be rotated or indexed in accordance with the number of coins which pass in engagement therewith. The feed of the coins when they are directed to the counting path is usually eifected by a feed roller, which is rotationally driven. The counting output of such devices, although relatively high, is, however, limited. The arrangement of the counters is also dependent on the accommodation of the mechanical counting mechanism which usually requires a relatively complicated and space consuming total construction of the machine.
The present invention provides a uniform money count ing device with different coin varieties which can be attached to the usual delivery chutes or tubes without making any change in the size of the coin channels.
The invention provides a construction in which the coins are delivered through a tube or chute defined by walls which provide a channel or passageway for the passage of the coins therethrough, which is of a size comparable to the coin to be measured. The exterior dimension of the tube defining the channels for the coins of various varieties are advantageously made of the same dimension or thickness. The invention provides a sensing head which may be fitted over the exterior walls of each channel and which-creates an oscillating field within the channel through which the coins are passed. The field line center of the sensing head is situated adjacent an edge of the channel at a location so that it will be at the average value line of the coin spaces and the row of coins which fall through the channel (that is, when coins are directed through the channel in abutting relationship, the space underlying the center of the sensing head, as measured across the coins and as measured between the coins, will be substantially equal).
In accordance with a preferred arrangement of the invention, a sensing head is connected with an oscillator amplifier unit by means of a flexible cable. In the circuit of this unit, there is arranged an electrical impulse counter at a suitable location in respect to the device. As soon as a coin cuts the field lines, the oscillation is changed and an output signal is released.
In order to obtain an exact counting of the coins,'it is not sufiicient to build up, at any suitable place of the 3,242,932 Patented Mar. 29, 1966 "ice coin channel, an oscillating field which is passed by the coins. Rather the oscillating field has to be changed by the interchange between coin and space between coins. For this reason, the windings or coils of the sensing head must be located with their sensor arranged about in the average value line of the coin spaces and the coins and should be adjustable on this line, for example, by using set screws or biasing means. I
, An advantageous embodiment of the invention is provided where the sensing head includes two legs which are arranged tostraddle the chute defining the. channel or path for the coins and includes a winding spool in each leg located in respect to the chute adjacent the edge thereof in a position so that sensing field will be at the value line of coin and interspace as mentioned above. For inductive sensing, the oscillating and feedback windings of the oscillator are arranged in the sensing head in a separated manner. Advantageously, the legs of the sensing head can be clamped onto the chute defining the coin channel at suitable areas due to the inherent springiness of the leg construction. The preferred location for the sensing head is at the upper end of a coin chute or tube. All of the coin channels for the various denominations of coins have the same exterior wall thickness while the interiors define coin channels or paths corresponding to the thickness of the individual coins which are to be counted. This permits the sensing head to be clamped to any one or all of the tubes for the various coin denominations with little difiiculty and to be interchanged, if necessary. V i
The means defining the coin chute or coin channel for the passage of the coins advantageously comprises; a nonme-tallic material preferably a thermal plastic material. Theimpulse counter may be an electric 'stroke coun ter known in and of itself with which it is possible to achieve counting outputs in the magnitude of about 3000 coins per minute. If higher counting outputs are required, then an electronic tube is employed which are also known per se. With such counting tubes, the counting output is'practically unlimited. The counting output of the inventive counting device is essentially higher than in the known mechanicaldevices because the counting takes place without any contact with mechanical elements and may take place during the free fall'ofthe coins. It is even possible to increase the speed ofthe coins which fall through the passage or channel for the coins by providing means, for example compressed air impulses.
Accordingly it is an object of the invention to provide a counting-device comprising a sensing head whichmay be oriented in respect to a tube or similar element defining a passage for the coins and which advantageously includes an oscillating winding and a feedback winding arranged adjacent an edge of'the path for the coins in a position such that the field line will intercept the coins and the spaces between the coins in substantially equal amounts, even when the coins are fed through in abutting relationship. v
A further object of the invention is to provide a sensing head for a coin counting machine which may be clamped over the exterior of the tubes for each denomination of coins in a simple manner for electrically indicating the number of coins passing through the tube by means of an amplifier and a counting device.
A further object of the invent-ion is to provide a coin sorting and counting device which is simple in design, rugged in construction and economical to manufacture.
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part ofthis'specificati-on. For a better understanding of the invention, its operating'advantages and specific objects attained by its use, reference should be had to the accompanying drawings and descrip- 3 tive matter in which there is illustrated and described a preferred embodiment of the invention.
In the drawings:
FIG. 1 is a somewhat schematic partial sectional and partial elevational view of a coin counting machine constructed in accordance with the invention;
FIG. 2 is a longitudinal sectional view of a coin tube with the sensing head and counting device schematically indicated in relation thereto;
FIG. 3 is a section taken on the line IIII-II of FIG. 2;
FIG. 4 is a bottom plan view on slightly enlarged scale of the sensing head;
FIG. 5 is a side view of the sensing head indicated in FIG- FIG.=6 is. a somewhat schematic indication of the arrangement of the oscillating and feedback coils in the sensing head;
FIG. 7 is an electrical diagrammatic view of the oscillating and feedback windings indicated in FIG. 6; and
FIG. 8 is an electrical diagram indicating the oscillator circuit.
Referring to the drawings in particular, the invention embodied therein comprises a counting device 1 having the usual conveying or feeding device 2 by means of which the ditferent coins are supplied to a sorting trail 3. The sorting rail 3 is of the usual construction, having an inclined track way with slots of a size corresponding to the various denominations of coins which effectively feeds the coins to chutes or tubes generally designated 5 provided for each coin denomination.
As-best seen in FIG. 3, the coin tube or chute 5 is advantageously made up of non-metallic elements, for example of a thermal plastic material, and advantageously includes a channel-shaped member 5 and a straight member 5 The members 5 and 5 are arranged as indicated in FIG. 3 and define therebetween a coin delivery channel or passageway 5 for the passage of coins 4. The width of the passageway 5 is made to correspond to the coin 4 which is to be handled thereby. The members 5 and 5 arev advantageously secured together such as by adhesive.
All of .the coin tubes 5 indicated in FIG. 1 are advantageously made of the same exterior thickness so that a unitary measurement for the leg distance of the sensing head 6.may be made. The sensing head 6, in accordance with the invention, is constructed with a rear or central web portion 6 and with two leg portions 6 and 6 The leg portions 6 and 6 are provided with coils or windings 7 and 8 which. are wound around suitable spools. The space between legs 6 and 6 defines an opening or gap 6 which corresponds to the exterior thickness of the coin tubes 5. A hole 9 is provided in the web portion of the sensing head 6 to accommodate a flexible shielded cable 10 which is connected to the coils as indicated in FIG. 6. The winding 7 is an oscillating winding and the winding '8 is a feedback winding, and the direction of these windings is such that the field direction is as indicated by the arrows in FIG. 7. The feedback winding 8 consists of two winding portions 8 and, 8 having a tap indicated by 8 The windings are part of an oscillator amplifier unit 11 having a connecting cable 12 which can be applied to a network potential and is usually connected via a transformer and rectifier which is transformed to a low voltage potential, for example, of 24 volts. A connecting cable 13 extends from the amplifier to the impulse counter. The impulse counter, for example, may be an electro-magnetic stroke counter or an electronic counting tube, each of which devices is known in and of itself.
The oscillator circuit indicated in FIG. 8 includes a transistor 15 having a base 16 connected with the oscill-ating winding 7 and having an emitter 17 connected to a potential meter 19. The transistor also includes a collector 1-8, connected with the input of the feedback Winding 8 The tapping point 8 lies at the line 20, which latter may be grounded. The other connection is through a line 21. It is applied, for example to 24 volts.
The coil 8 of the feedback winding 8 is connected at a diode 22 which, in turn, is connected to an amplifier (not shown). The amplifier preferably uses transistors. The impulse output is indicated at 23. As soon as metal cuts the field lines 24, the oscillation is changed and an output signal is released, which in the form of an impulse acts via lines, 13 on the impulse counter and thus switches the counter about one digit while each coin is counted. The field line center 24 is adjustable by moving the clamped sensing head 6. The field line center must be situated at the interspace which is formed by two subsequent coins and coincides with the average value line 24 of coin and interspace so that the sensing head can clearly recognize define differences, namely coin-interspace-coin. Thus, for example, when the coins are feeding through the tube 5 in a stacked abutting relationship, as indicated in FIG. 2, the same length of coin will be passed beneath the center line of the windings 7 and 8 as the length of space between coins when they are abutting. Of course, when the coins are widely separated as they are being fed, there will be a much greater space between one coin and the next so that the sensing becomes easier. -Thus, the speed of the coins can be counted and the occurring frequency thereby formed is merely limited by the given impulse frequency of the electro-mechanical stroke counter 14.- Thus, if an electronic counting device is employed, the impulse frequency may be as high as necessary.
The inventive coin counting device operates with a unit sensing head Which can operatev both with inductive and with capacitive sensing. In the latter case, condenser plates (not shown) will be embedded in the sensing head. The coins to be counted are not contacted and are not obstructed in their passage through the device. They may pass the sensing head during their free fall and at high velocity. The arrangementby suitable construction can be used to count preset amounts of coins by means of a selective switch.- It is important in this arrangement which metal the coins are made of and what diameter and what thickness they have. Theycan be attached to existing money sorting or money counting machines.
The counting device requires very little space and does not require any additional space which is not present, in any event, between the coin channels and the shafts or channels through which the coins fall. The mechanical elements for the mechanical mechanisms and their lines which usually lead to the counting mechanisms are not required. Instead, very thin cable connections are only required which permit the attachment of the impulse counters to any suitable area of the machine. Thus the counters may, for example,.be arranged in a ledge which is formed on the tubes in front of the machine if it is desired. An adding device may also be included with a counter 14.
Furthermore, there is a possibility to fit the arrangement with a switching device for optional switching by which previously set quantities of coins are countable. In such event, as is usually the case, the arrangement actuates the stopping device which stops the sequence of the coins after the preset amount of coins has been counted. The inventive device can be used in connection with the counting of any kind of coin varieties independently of the kind of material of which they are made, the diameter and the thickness of the coins and without changing the construction of an existing sorting machine.
While a specific embodiment of the invention has been shown and described in detail to illustrate the application of the inventive principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
