The purpose of the invention is to overcome the difficulties encountered with the aforementioned Beverage brewing with anointing dosage when skimming with coal or Like. Staggered beverages arise from the puffing, to avoid.

This foaming is mainly due to the escape of carbonic acid me dom drinks when the external pressure on the drink is reduced and depends on the temperature of the drink, its binding power for carbonic acid, the construction of the pipe system used, a steady, slow pressure drop and the turbulence created by the beverage as it passes through the Lei thrown in late driving, now with the usual tapping of Hand of a drink, e.g. 1 egg, with stronger pans simply the tapping process interrupted by the temporary closing of the tap and only waitar led Where the foam has settled in the glass, the way out is with self-employed Side-controlled tapping is not possible because it happens once when the tapping process is initiated started running time of the time control and in the meantime Untarring the tapping is finished before the previous amount of beverage is filled in and also a cage with each interruption following an interruption Opening the tap by one unit, so that the indication of the counter does not correspond to the number of glass fillings actually made.

According to the invention, a hand-operated one is used for Varaaendung diaaar @achteile Switching device provided by w @ lche initiated by opening the tap The tapping process for a Gatrunk can be interrupted any number of times and for any length of time Lot and during the interruption of the course of the set on a boatiomta Absapfdauar Zeitwerkes also interrupts the plumb line and slide following each interruption daa PUs ant dia bltorXlu6 dos counter. no influa ut.

The switching device acts on the opening and closing of the tap, to the switching on and off of a set to a bcatiamte duration Zeitrolaie and counting on a dia e number of tapped drinks units Counter aing robot by the counter the interruptions are not counted wriea. la The switching element for triggering a dispensing process is special Dcee ait the switching element for the interruption and restart of the filling process preconfigured by setting the common org in different switching positions or by certain movements between different settings, the release, causes the interruption and restart of a dispensing process.

Daa switching element consists in a preferred embodiment of the Creation in elaor pushbuttons, which only after reaching their depressed position the dispensing process during its automatic return movement into its outlet position triggers, if iodea is pressed further, the tapping process is interrupted for so long how the test remains pressed and every time you return to the starting position the tapping process is switched on again and it remains switched on until the Time relay of the Zapnmhn is finally switched off.

In the exemplary embodiments shown below, dio Required functions and gear movements of the taile duc beverage dispenser to be given carried out essentially by electron-magnetic means. However, there is nothing in ways, the same gear movements and functions through pneumatic, hydraulic or mechanical components by, for example, instead of a lifting magnet or a Magnsapthahn4a a piston-cylinder unit or mechanically influenced : to be used and instead of an electric stouarndou push button one such is used, which is a ratchet member when it is withdrawn from the depressed position mechanical influences which trigger causes the tapping process.

The dispensing process can be initiated using the push buttons mentioned * the durez coin slot and the pushbuttons take place.

This control box is can be connected to the network by a plug 23. The control box 22, which in the The lower part of FIG. 3 shows, on the one hand, a timer 24 for the setting the running time to be determined for the dispensing of a beverage unit. It consists of a synchronous motor 25 which, via a reduction gear 26, has a switching arm 27 one set by means of an actuating arm 28 at the beginning of each dispensing process Location during the dispensing process returns to its zero position, in which the Schaltara don motor 25 switches off by striking a contact.

The Stollars 28 kana by means of an adjusting knob 29 on a round scale 31 can be set to the term to be determined.

The switching arm 27 is at the beginning of each dispensing process from its zero sauaGolatundlestwichfederndc <6w * tiaeaAnachlag 32 the set actuating arm 28. When switching off the MotOM25, the dispenser is stopped at the same time direction of the current of the solenoid 17 closed, whereby the relevant dispensing process is finished.

In addition, the control box 22 contains a timer (Fig. 3) Counter 33, which has the task of the number of dispensed beverage units to count. With each dispensing process, the counter 33 counts by one unit @@ iter. In the Connecting lines 34 between the lifting magnet 17 and the storage box 22 is a From from «t» e bt. can be switched off.

A control lamp 36 is arranged above the push button 19 lights up when the relevant beverage container 7 has been emptied. The one used here electrical circuit is described in more detail below. Instead of the Control cape or at the same time so that the relevant door key 19 is blocked.

The taps 3 (FIG. 1) are usually provided with a cover plate 37 button 19 can be locked.

The taps 3 (FIG. 1) are usually supported by a cover plate 37 undocked, which is given away with holes 38 through which the outlet ends 39 of the step out of the individual taps 3.

Normally, the individual taps are switched on and off made automatically. However, there may be cases where the automatic drive suspends, e.g. due to power failure, gearbox malfunctions, overhaul of the system, etc., the cover wall 37 is made removable so that the switching arms 14 of the taps 3 can be moved directly by hand. To do this, solder the top end of the AbdeCkwand 7 usually closed by a lock 41, while the lower end is held on a central wall 43 by hook members 42. After unlocking the Lock 41, the cover plate 37 can be folded down and removed gunz.

Fig. 5 shows the electrical circuit diagram for the implementation of a Dispensing process with Kollnerbodienung in the rest position.

On the right of the circuit diagram are three rows I), II), III) of switching positions the switches shown at the same level in the circuit diagram, which during of the process of a tapping process anftrotQn. ' I). The push button 19 in the fuel pump 2 is nit oizwa in the rest position closed switch 45 and one in this opened castor 46 advertised, so that with their impressions counter 45 is opened and switch 46 is closed.

La Zeitwerk 24, the relay 47 acts on a switch 48, the is open in the rest position. The synchronous motor 25 of the timer 24 influences a switch 49 which is closed in the idle state.

Close switch 46 when pushing button 19 a circuit is made R, 50, 51, 46, 52, 49, 53, relay 47, 54, 55, 56.57 Mp, so that the relay 47 disconnects the switch 48 connected to it and at the same time See branch circuit R, 50, 58, 48, 49, 59, counter 33, 60, 56, 57, Mp forms, through which the meter is addressed, i.e. one that works together with the unit of the meter The pawl is pushed forward by completing the above circuit and the unit r @ d of the counter is rotated by one counting unit, with if necessary by the counter switching device arranged between the "ahlrdoro" of the meter the next higher counting wheel advances by one counting unit at the same time. The ratchet remains in their advanced position until the dispensing process in question is terminated Luge and then return to lbxo starting position.

Since the switch 45 is open, neither get the timer motor 25 after the solenoid 17 current. The indentation of the printed parts 19 therefore works accordingly the switch row I), in which the push button 19 is to be thought of being held down, neither the opening of the tap 3 (Fig. 1) nor the starting of the timer motor 25th

II). By releasing the push button 19 this goes under the effect their spring 20 back in their rest position, whereby they Switch 45 ior closes and switch 46 opens again.

Since the switches 48 and 49 of the timer 24 remain closed. ben, becomes «in circuit R, 50, 58, 48, 49, 59, counter 33, 60, 56, 57, Hp bogie * in @circuit R, 50, 58, 48, 49, 53, relay 47, 54, 55, 56, 57 Hp su R.90,98,48,92,49,61, ZtitMrk <aotor29,99,96,97, oX R, 50 58, 48, 52, 45, lifting magnet 17, 62, 57, Hp formed.

The solenoid 17 opens the tap 3, the time work motor 25 sotzt turns and the counter 33 remains below. étron.

The gwtwmtw current runs through the closed switch 48.

Due to the liubmagnet 13, the tap 3 remains open and at the same time dor ZtitwerkMotor 25 kept running until the running time set in the timer is reached. At this moment, the timer motor 25 causes the switch arm 27 III) diwOffanncdMSahaltwrw49, wedur <th <MPCü) Mtx. <TfOw dem lifting magneton 17 and for the time stamp motor 25 is opened, the solenoid 17 is through the Return spring 18 brought back in the starting position in which the Zapfh, 3goehlocaenundderZwitwwrtMaMtor29abeMtwIlt. <The counter 33 is stro @less. In order to the incremental counting of the counter 33 is completed by one unit. By becoming powerless des Belais 47 kehron the switch 48 and the counter ratchet in their initial positions return.

The switch positions according to row III have now been reached a return spring 63, which engages on the reduction 26 in the time work 24 (Fig. 3), the shelf 49 returns to its original position. The tapping process is now complete.

Should the tapping process be interrupted in order to avoid strong puffiness to give the foam the opportunity to breath, the pressure button 19 is pressed and hold it down until the foam has set sufficiently.

By pressing the push button 19 (Fig. 5) after starting the 6on Zepfvorcangee switch 54 is opened again and the 84h9 | Xr 46 geeoblosssn, again via the circuit R 500 51, 46, 52, 49, 53, relay 47, 54, 55, 56, 57 Mp dan 47 latex 48 closes and in secondary currents R 50, 58, 48, 49, 59, counter 33, 60, 56, 57 Mp is produced, the counter 33 remains addressed and seder the Zeitworksmotor 25 nor the Rubung net 17 get power. This falls the solenoid 17 from, the tap 3 closes and the timer is stopped.

The same state remains as long as the push button is held down will. If it is released, the above on page 8 and 9 under II described operations. The tap is opened again immediately and the Zeitwerksmogeset and gate 25 running / held until the set in the timer Duration is sufficient. Then the above on page 9 and close automatically 10 processes described under III, through which the tapping process is stopped, if not in between repeat the te It can be seen that during the interruption of the dispensing process by holding down the push button 19 neither does the GoUra flow out of tap 3, nor does the timer continue to run and the Payer continues to pay.

Bel derAusfhrunforadoaGetr'ncausbsramitünzanalösunK is in front of dam @ back the push button 19, through which the desired tap or the desired drink is selected to make the coin insertion, by which certain preliminary circuits be performed. The coin or coins have been placed in a coin slot 10 (Fig. 4), to which a coin channel 30 is connected and of the type known to a coin checker 65 leads, thrown in. A coin channel 66 (Fig. 6) is connected to the coin validator, in which the coin inserted on a microswitch 67 einoirkt. Above the push button 19 (.? ig. 4) is arranged oin money return button 40, on which a money return channel 40 'and a money return space 40 "are connected.

There is nothing in the balance, each of several taps 3 a pushbutton 19 to be assigned to Zeitwerk 24 and a coin checker 65 with its secondary devices.

But to keep the costs for a coin operated drinks dispenser low su laiton, the coin checker is assigned 65 to all existing taps, so that two or more taps 3 cannot be tapped at the same time.

This condition can be fulfilled without further ado, i Then between several printing states 19 there was a well-known Mochanian exclusion block which is an equal-BitS ,, pressing two or more pushbuttons prevented In the present case, electrical power has been used for this purpose Switching means used.

The process that occurs when performing os by throwing mint The initiation of the tapping process will be shown below at @and of the circuit diagram 6 explains which is also the Z switching state in the @uholage of the beverage dispenser is equivalent to.

To the right of the schematic are four vertical rows I, II, III, IV of Switching position of the switch located at the same height in the circuit diagram is shown. The timer 24, the counter 33, the coin validator 65 and the pump 2 with push buttons 19 and Hdbmagnet 17 for the Taps indicated.

The circuit diagram is drawn in the rest position.

Switch position I by inserting the coins into the coin validator 65 (Fig. 6 tit), equiv. 4, too, the Uikroachalter 67 is brought to the "3" position. As a result, the Sporrspule 60 falls and blocks the entrance for further coins don coin validator 65, in that the Uünzkanal 66 (Pig. 6) pared through the blocking coil 80 will.

At the same time, the @@ lais 70 receives power via the lines R 50, 81,; Bit position "3", 85, relay 70, 86, 56, 57, Mp and picks up.

As a result, the switches 68 and 69 are closed and the scarf ter 67 brought up to us "8". The ejgeooh is made of mechanical connection inside of the coin validator between the relay 70 and the microswitch 67. The relay 70 receives now his stroma Or R 50,58, 88, 71, 87, 69, 85, relay 70, 86, 56, 57, Mp.

Mor R 50, 83 the now closed switch 68, 52 is now voltage on switch 46 of push button 19.

Switch position II Pressing the push button 19 opens the Switch 45 and switch 46 closes. via R 50, 83, 68, 52 the now closed Switch 46,84, SC-holder 49,89,53, relay 47,54,55 56,57, @p becomes a circuit closed, whereby the relay 47 view, the switch 48 closes while the Switches 73 and 72 are opened. The switches 72 and 73 are in the circuit / the two other taps in the same way as switches 74 and 75 in de * shown here Circuit diagram. The switches 76 and 77 correspond to the switch 48 in the illustrated Circuit diagram in the two other atroakreiaen. Belaie70 * and 79 correspond to the relay 47 in the circuit diagram shown in the other two circuits. The circuits the other two taps were interrupted by opening switches 72 and 73. Via R 50, 58, 74, 75, 58, 48, 84 voltage is applied to the open switch 45, thereby does not yet see lifting magnet 17, which is connected to line 61 with switch 45 is. Likewise, the Z engine 25 is not yet running, and that via line 61 is also running the switch 45 is connected.

Schaltstollung III Durci releasing the push button 19 are through a spring 20 acting on it, the switch 45 is closed and the switch @ 46 6at opens. via R, 50,58, 74, 75, 58, 48, 84, 45, 61, solenoid 17,62,57, Mp a circuit is closed, whereby lifting magnet 17 attracts and via the SChaltarm 14 Fig. 3 of the Zaptb, ahn 3 opens. Via R 50, 58, 74, 75, 58, 48, 84, 45, 61, synchronous motor 25 of the entry note 24, 55, 56, 57, Mp @. becomes a circuit at the same time closed, whereby the synchromotor 25 SU starts to run. Simultaneously flows via R, 50, 58, 74, 75, 58, 48, 84, 89, 49, 89, 53, relays 47, 54, 55 56, 57, Mp The current, so that the relay 47 remains attracted. @ The same goes for Ré 5go 74 75 4, 75, 58, 48, 84, 89, 49, 89, 59, counting 33, 60, 56, 57, Mp of the 3troa, so that the counter 33 is actuated.

The mode of operation when the tapping process is interrupted by renewed Pressing the push button 19 takes place as follows: By pressing the Push button 19, the dispensing process is interrupted because the switch 45 opens and switch 46 closes. The lifting magnet 17, which operates via R, 50, 58, 74, 75, 58, 48, 84, 45, 61 got its current, drops off, as is the synchronous motor 25 of the Zeitwerkes 24 quietly, which consumes its electricity in the same way Setpoint time set on timer 24 is not further calculated. DeBeLeit70dewMaM) Tester 65 remains energized because via R, 50, 58, 88, 71, 87, 69, 87, 85, relay 70, 86, 56, 57, Mp the electrical circuit is closed. As a result, switch 68 also remains closed, over 5 R, 50, 58, 88, 71,87, 69, 87, 85, relays 70, 86, 56, 57, Mp the circuit closed is. As a result, switch 68 also remains closed, via R, 50, 58, 74, 75, 58, 48, 84, 89, 49, 89, 53, Relmis 47,54,55,56, 57, Mp, @elais 47 remains energized and via R, 50, 58, 74, 75, 58, 48, 84, 89, 49, 89, 59, counter 33, 60, 56, 57, Mp, the meter remains energized. It is therefore switch position 11. By releasing the push button 19 @ Dispensing process according to switch position III forges @ tzt.

Switch position IV When the set tapping time has expired, open SChalter 49 and 71. As a result of this, the counter 33 no longer receives any electricity because the Circuit r, 50, 58, 74, 75, 58, 48, 84, 89, switch 49 (now open), C-9t 59, counter 33, 60, 56, 57, Mp is not closed when it is closed. Relay 47 also drops from, there also R, 50, 58, 74, 75, 58, 48, 84, 89, 49, 89, 53, Belais 47, 54, 55, 56, 57, Mp is interrupted by opening switch 49. This also opens the Switch 48 and switches 73 and 72 close. By opening switch 48 the circuit R, 50, 58, 74, 75, 58, 48, 84, 45, 61, solenoid 17, 62, 57, Mp and the current circuit R 50, 58, 74, 75, 58, 48, 84, 45, 61, synchronous motor 25, 55,56,57Mp interrupted, so that the solenoid 17 fills and the tap 3 sohli * Bt and the synchronous motor 25 of the timer 24 to Still ~ etaod Jkooat. There also SChalter 71 is open, the circuit R, 50, 58, 88, 71, 87, 69, 87, 85, is also a relay 70, 86, 56, 57, Mp interrupted, whereby relay 70 drops out and thereby the switch 68 and 69 opens and switch 67 goes back to position I. Daduroh is the troakrcie Ré 50 81, 67, blocking coil 80, 82, 56, 57, Mp closed, so that the sporr coil 80 attracts and thus releases the money channel G6. By the nechaniache return spring 63 the switches 49 and 71 return to their original position.

The tapping process is now complete and the switch is on again their rest position.
