Due to this construction, furthermore, disturbances are extremely rare and in the case of one Relatively easy to fix.

Further details of the invention are to be found in the following on the basis of an exemplary embodiment will be explained and described, reference being made to the drawing. It shows

Fig. 1 is a block diagram of the inventive Control device, and

2a and 2b show schematic diagrams of details of the control device shown in FIG.

In the following, reference should be made to the drawing, in particular FIG. 1, in which the control device IO is shown according to the invention. This control device 10 is used for Controlling various functions for self-sellers or other coin-controlled devices, which are suitable for the sale of goods of various prices. Together with one Mini pulse generator 11 of the vending machine working Control device IO has a coin value counter 12 which is provided by coin pulse generator 11 The generated pulses respond as soon as coins of a certain monetary value are inserted. As soon as the monetary value counted in the coin counter 12 den Sales price of a certain product reached or exceeded, occur within the control device 10 different operations to determine how much money is beyond the selling price has been thrown into the mini pulse generator 11, whereupon the excess amount is returned, a sales process is carried out and the coin counter 12 is reset to zero.

The Münzv / ertzähler 12 is generally with a binary counter, a flip-flop counter, a Ring counter, a shift register counter or a magnetic core counter, preferably Solid-state switching elements are used to increase the immunity to interference and the size and to reduce the weight of the coin counter 12.

In the following description of a coin pulse generator 11 for 5-cent, 10-cent and Run out of 25 CeiH coins. However, it should be understood be that within the scope of the present invention also coins in other currencies Can be used.

The control device 10 according to the invention is operated in connection with a mini pulse generator 11, like him, for example, in a simplified form

ίο is shown in FIG. 1. The coin pulse generator 11 is suitable for receiving three different types of coins - for example 5-cent, 10-cent and 25-cent coins - and has three different coin switches 14, 16 and 18. which will be referred to in the following as 5-cent, 10-cent and 25-cent counters. The ^ -cent switch 14 closes its contacts every time a 5-cent, W-CciH or 25-cent switch is inserted, the 10-cent switch 16, on the other hand, after a one-time insertion of a 10-cent or 25 Cent coin, while the 25-cent switch 18 closes every time a 25-cent coin is inserted. Such coin pulse generator II are known.

The 5 cent switch 14 is connected between a DC input power source - VDC and the input of the coin counter 12 as shown. The coin value counter 12 is also connected via a first A'ist'anc to the input of a 5-cent return bar 20, which in turn is connected to the input of a gate circuit 22 with its output. The gate circuit 22 has a second input which is connected to the output side of the 10-cent switch 16. The gate circuit 22 also has a first, normally open output which is connected to the input of the coin counter 12, while a second, normally closed output is connected to one of several inputs of a remaining money counter 24. As long as the gate circuit 22 is switched through - which is caused by a signal from the 5-cent return bar 20 - it forwards signals coming from the 10-cent switch 16 to the input of the remaining money counter 24. Otherwise it forwards those from the 10-cent -Switch 16 signals coming directly to the coin counter 12.

The coin value counter 12 has an output which is connected to the input of a decoding circuit 26. The decoding circuit 26 receives signals via this connection as soon as the amount of money present in the coin counter 12 is equal to or higher than the sales price of the selected sales product. As soon as the output of the coin counter 12 is equal to the price set by a price switch 28, 40, the decoding circuit 26 forwards signals to the sales circuit via certain positions of a Koniaktsatzes 28 a, 28 b and 28 c. In Fig. 1 the price switch 28, 40 is in the 10-cent switch position 28 ″. The other positions of the price switch 28, 40 are the 15-cent switch position 28 Λ and the 20-cent switch position 28 r. Further items can also be provided, as this depends on the price of the products to be sold. The position of the price switch 28, 40 thus fulfills a control function when an output signal is passed from the decoding circuit 26 to a flip-flop circuit 30, whereby this flip-flop circuit 30 switches to its reached state. As soon as the FÜD-Flon-Kreis

reaches its energized state, an output signal is provided to a delivery drive circuit 32, whereby a dispense relay 34 is energized and a sell impulse is sensed. As soon as the [lip-Ilop-Kreis 30 is in its sales position. is also another signal via a line 35 to a second input of the Munzweit- / iilileisl2 supplied, whereby the same is reset v \ iid. The same signa] also becomes the excitation of one Zeilscliallkrciscs 36 used when aroused certain time interval mil.U and then a reset signal to the flip-flop circuit 30 feeds the thereby enters its normal resting state.

The output side of the 25-cent switch 18 of the coin pulse generator ΪI is - as shown - directly connected to the flip-flop circuit 30 via Koniakte 40Λ and 40c of the Prcissehaltcrs 28, 40. This means that when the 25-cent switch 18 is actuated - as long as the sales price of a selected item is either 15 or 20 cents - a signal is sent to the flip-flop circuit 30 to excite it. If the flip-flop circuit 30 is not already in its addressed state when the 25-cent switch 18 is closed, a signal derived from the 25-cent switch 18 will result in a change in the sale status of the I lip-l'lop- Circle 30. As soon as the 25-cent switch 18 closes, a signal is also sent to the remainder / iihler 24 via the contact set 40 ″ to 40 c of the price switch 28, 40 having several positions. The contact set 40 "to 40 c of the price switch 28, 40 has Cine I () - Cent-Position 40", a 15-Cent-Posilion 40 b and a 20-CeHt-PoSiIiDn 40 c, the conversion of this contact set 40 α to 40 c defines which input signal is fed to the remaining money counter 24. For example, the remaining money counter 24 receives an incoming signal every time the 25-cent switch IS is closed, regardless of the setting of the price switch 28, 40. The change counter 24 also receives a signal in its 20-cent position when the I0-Ccnt switch 16 is closed as soon as the gate circuit 22 is in the addressed state.

The remaining money counter 24 contains logic circuits responsive to input signals and causes an excitation a reverse motor control circuit 42 which in turn energizes a reverse motor 44. Every time when the reverse motor 24 is energized, a coin - usually a 5 cent piece - returned. At the same time the reverse motor 44 mechanically closes a switch 46 which receives a different input signal supplies to the cash counter 24, whereby the deposited amount by the size of the Amount of money of the returned coin is reduced. Any signal canceled in this way \ reduces the counting status of the coin counter 12 by the amount of the returned coin, what m> is continued until the remaining money counter 24 to a certain amount or zero has been. As soon as this state is reached. the remaining money counter 24 is in his Rest position, with an excitement of the RückzahlniottirstciierkreiM.-s42 and thus the repayment engine 44 occurs.

so a certain monetary value - according to the thrown in Coins - to count and issue control signals in other parts of the control device 10 and the auto seller can be used. As soon as the 5-cent switch 14 is closed by throwing a coin, an input signal is sent to an input circuit, which - as shown - consists of a resistor 52, a capacitor connected in parallel with it 54 and a further grounded capacitor 56 consists.

The input signals caused by the closing of the 10-cent switch H> are fed to an input circuit, which consists of a resistor and parallel-sounded capacitors 66, 68. This circuit also includes a capacitor 70 and a resistor 72. the charging path for the capacitors 66 in! 68 on.

As a result, the transistor 76 is built turned off and has two opposite On the other hand, resistance transistors 106 and 108.

As soon as a 10-cent slip is inserted into the coin pulse generator II, this causes the 5-cent and 10-cent switches 14 and 16 to close in succession. The first signal fed to the counting stage 48 corresponds to the closing of the 5-cent switch 14. The second signal is also fed to the input of the counting stage 48 via a path consisting of the 10-digit switch and the gate circuit 22. These two input signals result in successive changes in the destination of the first counting stage 48 and consequently produce a change in the destination of the second counting stage 50. The mode of operation is essentially the same as the mode of operation described above for two successive S-cent pieces. If two 10-cent pieces are thrown in in the same way, four consecutive negative input pulses - two for each 10-cent piece - are supplied to the output of the counter 12, whereby enough input pulses are generated to allow four changes in the state of the The counting stage and thus two changes in the state of the second counting unit 50 / u.

If, on the other hand, a 2.5-centimeter stick is thrown into the mini-pulse generator II, this first causes the 5-cent sensor holder 14 to be actuated, then the 10-centimeter switch 16 and finally the 2.5-centimeter sounder 18 by actuating the Miinzschaller 14 and 16 caused input pulses actuate the bistable counting stages 48 and 50 in the manner already described for 5-cent and 10-cenl piecesc, while the input pulse caused by actuation of the 25-cent switch 18 via ik'n Flip-flop circuit 30 and the dispensing drive circuit 32 energize the dispensing claw 34, unless the dispensing relay 34 has already been energized by the coin counter 12 in the usual manner. The path of the 25-inch input pulses caused by the coin switch 18 leads via a filter circuit consisting of the capacitor 60 and resistor 58 connected in parallel in series with a diode 110 and from there to the movable contacts 40 " to 40" of the price switch 40 At the time of this process, however, the first counting stage 48 has already been actuated twice by the coin switches 14 and 16, so that the second counting aid 50 has already received an input signal. This means that the counting stage is in its normal state and the counting stage 50 is in its counting state, which means the insertion of a 10-cent piece within the coin counter 12 before the 25-cent piece actuates the 25-cent coin could. If a 10-cent sale is to be carried out under these conditions, the counting stages 48 and 50 have already given a sell signal as soon as the second input signal has come in and the counting run 50 has been excited. If, however, a 15 or 20 cent sale is to be carried out under these conditions, the counting stages 48 and 50 no are not able to emit a sell signal because the appropriate sales condition is not present. Under these conditions, closing the 25-centimeter holder 18 in the 15-cent or 20-cent position causes a signal to be output via the contact set 40 to the flip-flop circuit 30, which in turn drives the output circuit 32 and 32 so that the drive relay 34 is put into action to carry out a sale. The cooperation of the price switch 28, 40 with the timer circuit 36 only enables a sale if coins with an amount equal to at least the sales price have been inserted, regardless of which combination of coins was used and which sales price was selected.

As soon as the price set by the setting of the price switch 28, 40 has been fed to the coin value counter 12 and registered within it, output signals are generated which are fed to the price switch 28, 40. With reference to FIG. 2a it can be seen that the 10-cent position28n is connected to the collector of the transistor 76 in such a way that the output signals of the counting run 48 - in a similar way to the pulses / 111 change in the state of the counting stage 50 - are passed over it. In the same way, the 15 cent position is 28 /. » Connected to the collector electrode of the transistor 74 via a diode 109. The position 2Hb is also connected to the 20-Ccnt position 28c via a resistor 111 , which results in a discharge path for the capacitor 115 present within the switching circuit. The 20-Ccnl position 28 c is connected on the one hand to the output of the second counting stage 50 and on the other hand to the input of the 5-Ccnt return circuit 20 . By setting the price switch 28, 40 , the sales price is set and it is also controlled which output signal of the coin counter 12 is fed to the flip-flop circuit 30. Such output signals are fed from the movable contact 28 (I of the price switch 28, 40 via a "diode 113 to the F" lip-flop circuit 30.

The flip-flop circuit 30 has two oppositely connected transistors 112 and 114 , which are arranged in such a way that the input signals emitted by the coin counter 12 are fed to the base of the transistor 114 via the contact salt 28. As soon as an input signal is fed to the base of the transistor 114 , the flip-flop circuit 30 is made to respond, whereby the Tran sistor 1 14 passes from its conductive to its non-conductive state. This generates a positive pulse at a resistor 116 arranged between the collector of the transistor 114 and the base of the transistor 112 , as a result of which the transistor 112 becomes conductive.

A further resistor 118 is arranged between the collector of the transistor 112 and the base of the transistor 114. The aforementioned opponent

Stand 116 shows a higher resistance than the signal enters, it slurps at the collector of the Tran Resistor HK on, so that the base of the transistor sistor 112 existing potential up to the vicinity of voi 114 gets into the conductive state sooner than the zero, whereby the positive charge potential! de: Transistor 112, as soon as the circuit learns capacitor 144 for the first time and the same via dii is excited. If this were not the case, it would be possible for 5 resistors 140 and 142 to be discharged; thereby win that the circuit each time a sales cycle for one dependent on the line constant of the circuit; triggers when the plug of the self-seller has a positive potential at the base de in time interval; a socket is plugged in. Maintaining the base of the Tran transistor 46 so that the same fiii sistor 114 thus initially receives a higher period of time in its normally conductive state: Potential as the base of transistor 112 so that io remains. During the discharge of the capacitor transistor 114 initially in its conductive 144 decreases that at the base of the transistor; State. As soon as the transistor 114 is in its 146 existing potential or becomes negative, conductive State is, the base of the transistor 146 in its non-conductive Transistor 112 negative bias so that state occurs. As soon as the transistor 146 has its if this transistor is kept in the non-conductive state, it loses conductivity, this rises at the collector will. However, as soon as a sell signal occurs and the existing potential of one through two The base of transistor 114 is passed, see the collector and a positive voltage change the bistable flip-flop circuit 30 in a source arranged resistor 148 brought about a zero count position about, in which the transistor 114 in potential to a positive potential. Through this reaches its non-conductive state and the tran- 20 is called a current through one from another sistor 112 becomes conductive. At the same time, resistor 150 is given a base in series with diode 152 another transistor 128 by means of the circuit formed from the base of transistor 114, the resistors 120, 116 and 122 formed thereby the conductive state of this transistor Voltage divider circuit a positive voltage, where 114 is restored and the flip-flop circuit 30 in by the normally non-conductive transistor 25, its normal non-sell position is ready 128 enters its conductive state. for receiving another sales impulse

As soon as the transistor 128 is conductive, it is brought about.

The further transistor 134 arrives, which thereby becomes conductive capacitors 154 and 156 in a positive manner. This causes a current to flow through the charged state as soon as the flip-flop output relay 34, which in parallel with a diode 135 35 circuit 30 reaches its normal rest state, is connected to a positive voltage source. which the transistor 112 is non-conductive and which as soon as the output relay 34 with its contacts transistor 114 is conductive. As soon as α responds to the flip-flop 34, a sales cycle is carried out. Circuit 30 a sell signal is received - whereby a circuit of the self-seller is closed with the conductive states of the transistors 112 and 114. The diode 135 serves to protect the 40 reverse - the potential present at the collector transistor 134 against voltage peaks of the output electrode of the transistor 112 is reduced to zero, whereby the charges of the

As long as the coin counter 12 is in its reset state, the positive potential for charging the detector 184 is no longer available. The one on this one Capacitor 1X4 existing charge is thus through the resistors 178 and 176 and the I.adekreis of transistor 108 derived.

The. ^ - Cent return circuit 20 has another switch 16 via the cash counter 24. Since the circuit is open, the diode coins connected with one side to the 25 but the collector of the transistor 76 which operates the 10-cent switch 16 first operate the .S-cent switch 14 - 174 and one side to the collector that which naturally leads to a change in the state of transistor 108 connected resistor 176 to counter 48 - will form the coin counter. The common connection point of FIG. 12 has been brought out of its reset state. Diode 174 and the resistor 176 is connected to a 30 At the time of actuation of the 10-Centwcitcren vVidcrstand 178_, which is connected to switch 16 by a first coin accordingly its opposite side on the common

In the reset state of the coin counter 12, both transistors 76 and 108 40 counting device exist. According to the Darleitend, whereby the potential at the connection position, the remaining money counter 24 drops two similar places to zero. This connection point is bistable flip-flop circuits 186 and 188, which are connected to the gate circuit 22 with coupling resistors 190 and 192 via the resistor 178. soften again with the collectors of normal

The gate circuit 22 is designed such that the 45 conductive transistors 194 and 196 and the signals routed away from the 10 cent switch 16 are the basis of normally non-conductive transistors either the coin counter 12 or the remainder 198 and 200 are connected. Further coupling money counters 24 switch on. The of the 10-C ^ nt- resistors 102 and iO4 are in a similar way with Signals generated by switch 16 are negative pulses, corresponding collectors from the normally the common connection point of the 50 non-conductive transistors 198 and 200 and the capacitors 66 and 68 are supplied. The other bases of transistors 194 and 196 are connected. the The side of the capacitor 68 is grounded with the resistors 190 and 192 are usually such a capacitor 180, the resistor 172 and the chooses that they have a greater resistance than that Diode 182 connected. The diode i82 is to have its respective resistors 202 and 204, opposite side over the 5 cent line at 55 so that a suitable reset position of the FHpdcm Coin value counter 12 connected. The between flop circles 186 and 188 is guaranteed before These circuits appearing on capacitors 68 and 180 are energized first. The reset binding mechanism results together with the diode 182 state is that state in which the Trancinc Circuit to perturb a second input signal at si 194 and 196 conductive and the transistors the input of the coin counter 12 depending on 60, 198 and 200 are non-conductive.

The reset circuit 20 sets the reset state transistor 194, which thereby in its non-conductive des Münzwerl / .ählcrs 12 as soon as the transistors 65 state is set.

Once through the conductive states of the flip-flop circuit 186

the reset state is no longer maintained, so that no signal is supplied to the reset counter 24 can be.

be reversed. The same input signal is received Connect another diode 208 to the base of the transistor 196. by which it is brought into its non-conductive state and the current states of the flip-flop circuit 188 be turned over.

The collectors of transistors 194 and 196 are also connected to corresponding diodes 21 (1 and 212 connected, which together form an "or" gate, which conducts a positive potential to the base of a further transistor 214, so that the same in its conductive state when one of the two transistors 194, 196 is non-conductive. This will in turn, a positive potential is passed to the base of a further transistor 216, so that it is conductive will. This causes a current to flow through the one connected to the collector of transistor 216 Winding of a payback relay 218. A protective diode 217 is arranged in parallel with the payback relay 218.

The return relay 218 is arranged within the return control circuit 42 in such a way that when the relay contacts 219 of the return return 218 close, the circuit of the return motor 44 is closed. The reverse motor control circuit 42 knows; according to Y ig. 2 b of a voltage source leading lines L _{ and / .., as well as normally open relay contacts 219 and the reverse number molor 44. Each time the payback motor 44 is energized, a coin - in the present embodiment a 5 cenl coin - is refunded. When the reverse motor 44 is excited, the motor switch 46 is also closed, which, similar to the miniature switches 14, 16 and 18, sends out negative pulses that are passed to the input of the unstable flip-flop circuit 186 located within the reverse dial 124, so that this flip-flop circuit 186 changes state. Regardless of the state of the return circuit 24, each pulse of the motor switch 46 causes a change in the bistable flip-flop circuit 186 and every second pulse causes a change in the state of the bistable flip-flop circuit 188. This RückzahlvoiLNiiig is continued until the flip-flop -Circles 186 and 188 of the return circuit 24 reach their reset positions.

The setting of the price switch 28. 40 controls the way in which the impulses of the 25-Ccnl-Sehnllers 18 to the remaining money counter 24 and the flip-flop circuit 30 are supplied. As long as the Price switches 28, 40 according to FIG. 2 b is in the 20 cent position, the closing of the 25 - ('eni-Sdia1ters 18 caused negative impulse over a diode 220 is fed to the base of transistor 94, causing a change in state of the flip-flop circuit 186 enters. The same pulse is also sent to the base via further diodes 222 and 224 of transistor 196 released, whereby a change in state of flip-flop circuit 188 takes place. this causes a repayment process in the manner already described. Note that in in this case both flip-flop circuits 186 and 188 themselves Belinden in the addressed state as soon as a

After a sales and return cycle has been carried out, the control device 10 enters it original rest position and is ready for the next sale.

If, on the other hand, the price bracket 28.40 is in the 15-cent position instead of the 1 \ c \ 20 cent position, a negative pulse triggered by the 25 cent switch 18 is sent to the flip-flop via the aforementioned diode 228 Circuit 30, which triggers a vend cycle The same pulse is also passed through the diode 224 to the base of the transistor 196, the switching state of the flip-flop circuit 188, but not the flip-flop circuit 1H6 This causes the payback motor 44 to be energized to dispense a coin and the switch 46 is closed during the payback cycle so that a negative pulse can be applied to the I 'input of the first flip-flop circuit 186, thereby turning transistor 194 on nonconductive and transistor 198 becomes conductive After the first payback operation, the flip-flop circuits 186 and 188 of the payback circuit 24 are in the same state as in a simple payback cycle energized a second time, which triggers a second repayment cycle before the remaining money counter 24 goes into its idle state.

However, if the price switch is 28.40 in its The 10-cent position is reached by actuation of the 25 cent switch 18 caused a negative pulse to the base of transistor 194, causing The flip-flop circuit 186, but not the flip-flop circuit 188, changes its state. This state of the Remaining money counter 24 causes the repayment motor 44 to be excited by the "or" gate with the Diode 210 which is conducted through that from the collector of transistor 194 to the base of transistor 214 positive potential gets into its conductive state, creating a payback cycle - as above described - is triggered. Thus, when switch 46 is closed, a negative occurs Input pulse to the base of transistor 198, making it non-conductive and the transistor 194 becomes conductive. As soon as the latter reaches its conductive state, the collector potential is noticed Zero off. This causes a negative signal to be sent to the base of the collector at this point in time Conducted conductive transistor 196, whereby the same non-conductive and the transistor 200 conductive vvird. As a result, a positive potential is again applied to the base of the transistor via the diode 212 214, which triggers another repayment process. The remaining money counter 24 then operates in the same way as already in the price holder's 28.40 15 cent sale position has been described until finally three coins have been given.
