Description

GERMAN

The invention relates to a controller for vending machines using selectors for Registration of the inserted coins of different types, for each type of coin a contact to Triggering a value-corresponding forwarding of the assigned voters is provided, of which each adds up the insertion of a certain group of coin types in the respectively smallest coin type and via a lamella, which is actuated directly or via a means of the selection device Price contact point according to the price of the goods selected or according to one of the Summation selector hereby assigned partial amount of the price of goods is put on voltage, in the resultant A pre-relay is energized in a defined position and in the case of the release of the goods issue and, if applicable the return of the overpaid amount takes place when the sum of the by the voters registered amounts has reached or exceeded the price of the goods and according to the caused thereby Excitation of all pre-relays of the circuit led via the contacts connected in series of these relays is closed to excite the release relay. For controls of this type with several totaling selectors One of the main tasks is to trigger the handover of goods, even with such To ensure coin insertion in the amount of the respective set price of goods, which only from one Coin type or consist exclusively of the coin types assigned to a summation selector or otherwise a forwarding that deviates from the forwarding provided by the respective marked voter positions the summation selector. In the known controls of this type the "deviating" currency positions in this sense accepted and retained as a given, which means that the solution to the task mentioned in these controls is in principle all in in this way to record or use possible voter positions for the excitation of the release relay, partly because the excitement by means of several over the voters according to the possible Coin combinations of the circuits guided by these registered coin types is enabled, partly because for one or more coin types apart from or instead of the redirection of voters Relay circuits for exciting the release relay by means of one or more selectors bridging Circuits are provided.

Since this principle is based on the registration of a certain amount depending on the Coin compilation of the slot can lead to different positions of the summation selector, is in the known controls for determining control for vending machines

of the overpaid amount, which is due to the registration of the overpaid Price of goods beyond coin insertion takes place, no uniform starting position of the totalizing selector given, so that the registration of an overpaid amount of a certain amount is also to different voter positions or those marked as marked by different numbers of steps can lead.

This results in the handover for the control of the a changeover relay that triggers one type of coin and is usually excited via the lamellar levels a selector triggered by the release relay takes place, that for the detection of this Voter positions for each price of goods at least one specific connection circuit between the Changeover relay and the slat levels provided for this purpose are produced or in the form of each a commodity price of certain lamellar levels must be available, which is the case with a large number of commodity prices is disturbing.

In addition, with the mentioned controls with several according to the possible coin compilations of the price of the goods via the electoral tripping circuits to produce the corresponding Connections especially with a variety of coin types and with higher prices of goods because of the increasing number of coin combinations for each price of goods a switching element for the production of a Variety of connections required.

There are also proposed controls in which only one to register all types of coins Summation selector is provided, which inevitably has an influence on the coin combination Voter position is switched off. When using coins with very different values occurs this, however, has the disadvantage that the voters have to register the higher coins in terms of value a very large number of steps must be switched on, which is as small as possible for the purpose of compliance Times for the functional sequence to very high switching

Compared to the known controls, the input leading to the return of these amounts can thus be used mentioned control of the changeover relays by means of one for all commodity prices and possible combinations of the coin slot valid connection circuit between the changeover relays and the intended Slat levels of the post-selectors are carried out.

Accordingly, it is necessary to set the control according to the invention to a price of goods Regardless of its amount, only one switching element for production per goods price or per type of goods only one connection at a time on each of the summation selectors provided for energizing the release relay, while switching devices for the production or activation of various connections not required for the changeover relay and thus eliminates the disadvantages mentioned in this regard are.

The further implementation of the inventive idea Mechanical devices provided are shown in FIGS. 2 and 3 in an exemplary embodiment shown schematically.

As already mentioned, these devices are provided according to the invention to control the temporal sequence of the planned in control systems of the type mentioned S expensive functions to ensure and in particular to avoid disruptions due to the unhindered insertion of coins.

This is essentially achieved by a fundamentally new principle of application of known devices, which essentially consists in the fact that for the generation or for the release of the excitation currents, which are provided for switching the dialer as a result of the coin insertion and for triggering the control functions caused by this, a switched on by the inserted coins and z. B. driven by an electric motor, acting in a known manner program switching mechanism with one or more z. B. on driven shafts 211, 212 fixed control disks or control rollers 210, 213 for the program-like actuation of several contacts η or N is provided, in detail on the program contacts η according to the execution of the S expensive discs or control rollers continuous currents and or or Pulse currents of a certain length are generated or released from the pulse excitation of a pulse generator N driven synchronously with the shafts 211, 212 or by these, while the position of the control disks or S rolls expensively determines the time sequence in which the contacts mentioned η or N are actuated.

In this case, the coin contacts or relay contacts provided for triggering a certain further switching of the selector are individually connected to such program contacts η in terms of circuitry, which by means of the design of the control disks or control rollers 210 or, as 213, acting on them by cams or sliding tracks, the corresponding number of pulses or release from the pulse excitation of the aforementioned pulse generator N , while the relay contacts provided for triggering the control functions required by the further switching of the selector are each connected to sol-Ä ^ rogiärcMirikontakten, which in a corresponding manner to close or open the excitation circuits provided for this purpose are set up.

Due to the above-explained application according to the invention, these from other areas of the Circuit technology known device for controls of the present type, the task arises a temporal synchronization of the actuation triggered by the unhindered coins inserted

ίο to bring about the coin contacts and the programmatic actuation of the program contacts η connected to them in terms of their circuitry.

This is achieved in the present embodiment of the control according to the invention in that a circular drive plate 26 or 27 provided with one or more cutouts is provided in the coin channels 22 separated by coin types and by means of the inserted coins 21 with the associated coin contact w z. B. via a lever 28 in such a way that the for example attached to a driven shaft 25 and rotated by this discs in a known manner by means of said cutouts take the coins individually and guide them past the levers 28, wherein these are brought out of their rest position and actuate the respective associated coin contacts w. The execution of the named levers 28 and the drive of the named shafts 25, 210, 212 is in this case

seen that the operating times of the program contacts η w coincide with the means of said cut-outs set times of a possible operation of the Münzkontakte, while by a corresponding position of the carrier plates 26, 27 to each other and to the other control discs or control rollers 210, 213, the simultaneous excitation of a Rotary solenoid is prevented by several of the coin contacts or the aforementioned relay contacts, so that all coin slots, even if coins are inserted at the same time or very quickly one after the other, trigger a value-related switching of the voters according to the time sequence determined by this program and the related disadvantages mentioned at the beginning are eliminated .

The further features and properties of the invention can be found in the description below, in which as an application example of the invention, the control of a machine to give any Types of goods or tokens with a price of 5 Pfennig to DM 5.45 with a price scale of 5 to 5 Pfennig is described,

The circuit implemented in accordance with the features of the invention explained in principle above this machine is shown schematically in FIG. First, the essential control processes are presented explained in detail and then the entire functional sequence in connection with some operating examples described in detail.

Six types of coins are provided for insertion, namely coins of 5, 10 and 50 pfennigs as well as of 1, 2 and 5 DM, to which the correspondingly designated coin contacts W ₅ , _m ₁₀ , W ₅₀ , W ₁₀₀ , W ₂₀₀ or W ₅₀₀ ( Fig. 1) are assigned individually.

An eleven-part selector K ₁ with the rotary magnet DK ₁ and two contact levels and selector arms k _ta and k _± & are used to add up the 5 and 10 pfennig coins grouped together in coin group I, while the total of the 50 pennies grouped in coin group II Pfennig, 1 DM, 2 DM and

the negative potential being applied to the changeover relays WA or WD via the same contacts. The changeover relays are connected in multiple circuits to the post-voter levels P _{1 a} and p _{2 a} , so that their excitation during the rest of the switching of the post-selectors is every two switching steps, i.e. according to the number of 10-pfennig or 10-pfennig or 1-DM values of the overpayment is made. The changeover magnets WM ₁₀ and WM _{100 are} actuated by means of the contacts Wa _{1 and WCi 1} , through which the corresponding number of 10-pfennig or 1-DM coins is dispensed.

For the surrender of the overpaid assessment, which corresponds to the difference between the insertion of DM 3.00 and the set price of the goods of DM 2.70.

Now, as the last of the group W _7, the program contact n _{7 d is} briefly closed and this energizes the relay Z via the contact x ₂ , so that the return of the summation selectors K ₁ and K ₂ takes place as described.

In the basic position of the summation selector K ₁ ίο the relay T is energized, so that the impulses of the pulse generator N reach the rotary magnet DP _{1 of} the subsequent selector via the contacts ^ ₃ , ^ ₁ and J ₁ and this is also returned to the basic position the relay 6 "is energized via the arm P _{1 c}

The coin values of 5 or 50 Pfennig 15 and the contact S ₁ opens.

After the above voter movements have been completed, the program briefly activates the program contact n _7C , the one with the selector arms P _{1 b} and p ₂ f, as well as via the corresponding selector levels with the changeover relays WB and WC to control the for the distribution of 5- and 50 -Pennig coins provided interchangeable magnets WM ₅ or WM ₅₀ .

The walking of the change-over relay WB or WC to said selector planes compounds are carried out so that in each case the excess amount in accordance with the operation of the program contact Ji ₇ remains _c either ineffective or the excitation of the change-over relay WB or WC result, the

After the relays E and C have been de-energized, as described in the previous examples, the control system is de-energized again, as described.

4. Operating example

The interaction of the transfer and return processes described above is to be explained using a further operating example in which the largest possible change amount comes to hand.

This is the result of the difference between the smallest and largest in terms of value for use intended coin types. With reference to the exemplary embodiment on which this description is based

the actuation 30 of the invention, this amount is DM 4.95.

then via the contacts Wb ₁ or 1 of the associated alternating magnet WM ₅ or WM ₁ and thereby trigger the surrender of a 5- or 50-pfennig coin.

As can be seen from Fig. 1, the connection circuits for connecting the said changeover relays to the levels P _2a and P ₂ I of the post-voter P _{2 are} opposite to the corresponding connections to the levels P _{1 a} and p _{2a of} the post-voter P ₁ offset by one step in the direction of rotation.

This is related to the previously described transfer of the above-mentioned added value of 50 pfennigs triggered in position 1 of the post-voter P _{2 and causes the value registered by the post-voter P 2 to} continue by the transferred value 45 through the 2 DM coin after position 5, the fee is reduced by 50 pfennigs. For this reason, the

As before, the set price of goods is DM 2.70. It is assumed by the user of the machine that he initially received a coin of 5, 10 and 50 pfennigs as well as a coin of 2 DM, d. H. all in all Throws in DM 2.65, but now no more change, only a coin of 5 DM available has and also throws this in.

With regard to the description that has already been made, the essential control processes such as follows:

Through the 5-penny coin passes the Wählerarm k _ta to position 1 and the 10-penny coin further to position 3 by the 50-penny coin, the arm reaches the position k _{2 a} 1 and

The pre-relay B is energized, so that the * selector arm p _{2 a} moves from position 0 to position 10 through the 5 DM coin and in position 1 the program contact group n ₆ becomes effective and ten im-

In the present operation example was in-50 pulse through the contact n _e j, releases to the selector couple K _1, P ₁ Series overpayment of Nachwähler P ₁ in the STEL, whereby the Wählerarm k _{1 a} switched from position 3 lung. 6 The relay 5 is thus de-energized, so that when the program contact is actuated

Post-voter P _{2 is} not required in the aforementioned transfer process.

and J ₂

n _{7 a} relay X via contacts f ₅ , e ₂

excites and is held via the contacts x _s and c ₄ .

The ten pulses now released via the program contact n ₇ b reach the rotary magnet DP ₁ via the contact X ₁ , whereby the arms of the after selector P _{1 are switched} from the position 6 via the basic position 11 = 0 to the position 5. In this case, after the switchover mentioned in the basic position, the changeover relay WA is now energized in positions 1, 3 and 5 via the selector arm p _la , which moves from position 0 to position 9 via the after position 4 and arm p _la.

The pre-relay A and thereby the release relay F are excited via the arm k _{1 a.} After relay E has dropped out, program contact group n ₇ becomes effective and energizes relay X via contact n _7a via f ₅ , e ₂ and J ₂ and relay Y via the contacts.

The program _{contact M 76} now releases ten pulses to the rotary magnets DP ₁ and DP ₂ via the contacts X ₁ and y _t . As a result, the arms of the post-voter P ₁ move from position 9 via position 0 to position 8, whereby in position 0 via arm P _{1 c}

e ₂ and v _s

Contact Wa ₁ a three-time actuation of the switch 65 energizes the relay S and via the contacts J ₃ and

magnets WM ₁₀ and thus the handing over of three 10-pfennig coins is triggered.

The subsequent actuation of the program _contact n 7C remains ineffective in this example, it is held while in the positions 1, 3, 5 and 7 via the selector arm P _{1 a} the excitation of the changeover relay WA takes place and the changeover magnet WM ₁₀ each time a 10 Penny coin, ie total

that a total of 30 pfennigs are given away 70 40 pfennigs are spent.

At the same time, the arms of the post-voter P ₂ move from position 10 via position 0 to position 9, whereby in position 0 the relay V is energized via the arm p _{2 c} and held by the contacts V ₂ and; y ₄ , while in the positions 2, 4, 6 and 8 over the p Wählerarm _{2 a} the excitation of the change-over relay and WD takes place by alternating magnetic WM _in each case a 1-DM coin, ie a total of 4 DM reach the Hergabe.

Now the contact M _{7 c is} briefly closed, whereby the changeover relay WB is energized via the selector arm p _lb , which is now in position 8, and a 5-pfennig coin is issued by the changeover magnet WM ₅ , while the arm is now in position 9 ^ ₂₀ the WC changeover relay is energized and a 50-pfennig coin is given away by the WM _{50 changeover magnet.}

After this, the program _{contact M 7 d} causes the return relay Z to be energized via the contacts X ₂ and y ₂ , as a result of which the control unit returns to the starting position and is de-energized.

The triggering took place accordingly with the registration of the goods price of DM 2.70, while in total DM 4.95 were repaid, which is the difference between the price of the goods and the amount deposited of DM 7.65.

From the explanation of the control given in the above operating examples, it can be seen that the switching of the selector, apart from the coin-operated contacts, is essentially triggered by the program contact groups M ₅ , H ₆ and M ₇ , with the resulting control processes being the same for all goods prices and It is only determined by the composition of coins in the slot which of the contact actuations taking place in the program or in which order they are triggered and what results they lead to.

In this case, the contacts χ ^ and y _i prevent the program contact groups M ₅ and M ₆ from becoming effective during the voter movements triggered by group M ₇ to control the giving of change, while when the selector of contacts ^ ₁ returns, these functions of contact groups M ₅ , M ₆ and M ₇ makes impossible.

Furthermore, as mentioned, a corresponding position of all control disks 210 or driver disks 26, 27 (FIG. 2) prevents simultaneous impulses being sent to the same rotary magnet and thus ensures that the processes described run smoothly.

In the event that the control system fails, a return relay R is provided which, when energized by the contact VE operated by means of the so-called failure button of the machine, maintains itself via contact r ₂ , with the excitation circuit not only via contact VE via one of the lamellas the basic position not contacting closed lamellar plane P _{c 1,} p _{2 c,} k _b and _{k, for example,} the existing selector, the relay C is guided through the contact C _3, which, as known, during the execution of all the operations triggered by Münzbetätigung as well as excited enable relay F is excited.

Accordingly, the energization of the relay R is only caused by actuation of the contact VE if no triggering has taken place after a coin has been inserted, whereby an improper actuation remains ineffective.

If, however, the above conditions are met, the relay R excites the return magnet RM ₁ via the contact r _x, the relay C excites via the contact r ₃ and the return relay Z is excited via the contact r ₄ inserted coins as well as the return of the control to the rest position.

It goes without saying that the invention is not limited to the embodiment described, but rather also includes the variants and simplifications made using the inventive principle according to the claims are realized.
