Coin sales device

The invention relates to coin vending machines which the delivery of the goods to be sold is electrically controlled and relates in particular to devices that have a Have setting relay that responds to the input of the correct coin amount in the device and the delivery of the goods causes or allows »

Such setting relays are often used in devices in which the buyer has the choice between two or more goods, the selection being made by pressing suitable selection pushbuttons after the setting relay has been actuated by entering the required coin amount. By pressing the "Wähldruckknopf automatically dispensing the selected product _s A choice of goods, for example, in many beverage dispensing machines vorgesehen.Die drinks can be completely different (z.Bo coffee and cocoa or chocolate) or Unt-erschied can in Additives of the beverage (e.g. coffee with or without milk and / or sugar).

The invention is directed to providing an improved arrangement for an electrically controlled coin vending machine.

According to the present invention there is provided a coin vending machine created which one of a variety of available

Goods selected goods by entering the correct coin amount and then closing one of the selected goods outputs electrical circuit, the goods are included in two groups and the device electrical switching devices has, by actuating the sales price of at least one group independently of the other thereby changeable is that the value of the coin amount is changed, which must be entered into the machine, so that that of the goods which can close an electrical circuit assigned to a group.

The switching devices are preferably designed in such a way that they set the sales price of the two groups of goods independently of one another allow to change »

Individual coin slots can be assigned to the goods, in which case the goods are selected simply by the fact that the coin amount is inserted into the corresponding slot. Appropriately, however, the machine has only one, common coin slot for the various goods, whereby the goods are selected by actuating selection devices, by which actuation the assigned electrical circuit closes and the selected goods are delivered.

The device can contain two setting relays, of which the first two with the electrical one assigned to the one category Circuit in series working contacts and that the second has two working contacts connected in series with the electrical circuit assigned to the other product group, wherein the switching device is adjustable so that the first setting relay and the second setting relay after input of a lower or higher coin amount is excited and closes its contacts after excitation, so that after entering the lower value Coin amount a commodity of a group and after

809809/0086

Enter the higher value coin amount for goods from the other group pe can be delivered «.

The second setting relay preferably has other working contacts that are parallel to the contacts of the first relay, see above
that when the second relay is energized, the first relay is also energized. This arrangement makes it possible to have a cheaper one
Goods from one group are also returned if a coin amount has been inserted that is sufficient for the more expensive goods from the other ™ group »

The switching device can also preferably be designed to be adjustable so that the value of the required for the delivery
Coin amount is the same for both product groups.

The switching device can have a first switch which
can be brought into a first position in which an electrical connection is established via the switch to the first relay and
which can be brought into a second position in which an electrical connection can be established via the switch to a second relay

If there is an order according to the preceding paragraph and this arrangement "continues to be constructed so that the first relay is always energized when the second relay is activated, then are the following operational changes or operational variation options given i

1. If the first switch is in its second position, both relays are activated after inserting a coin energized, i.e. the goods of both groups are sold at the same minimum price * The second counter is located is preferably in the "OFF" position, however the position of this switch does not affect operation

2 * If the first switch is in its first position and the second switch is in its second position, only the first relay is energized after entering a coin and the second relay is also energized after entering another coin only one product of one group can be handed over to a coin, while after entering two coins a choice can be made between the goods of both groups »

2e The first switch is in its "OFF" position and the second switch in its second position, then the first coin inserted does not have any influence, but rather only by entering the second coin becomes the second Relay and thereby the first relay energized »On this Both groups of goods are sold at the same price,

Me device can also be used to hold higher coins Category are formed, the arrangement being made in this way will,; that by entering a coin of a higher category the

second relay and therefore also the first relay is energized o Es there are therefore the following three further options:

If the "two switches are in the" OFF "position the device only delivers goods from each of the groups if a coin of a higher category has been entered willo

2ο The first switch is in its first position and if the second switch is in the "OFF" position, the input of a single coin gives the lower one Category a product of the group controlled by the first relay is free for delivery. Optionally, by entering a coin of a higher category, by energizing both relays, a commodity from both groups for delivery Approved.

3 «If the first switch is switched off and is located the second switch in its second position, two coins of a lower category must be entered before the first relay is energized. »A coin of a higher category again causes both to be energized Relay.

The switching device can further contain a third switch, which can be switched between two positions and when it is switched, the different one by inserting coins Category reverses the influences produced in the machine. This means that in the first position the above described Processes are caused, while in the second position the input of a coin of a lower category directly energizing the second relay and entering a coin higher Category the excitation of one or both relays, if over-

809809 / 008G

anyway, so only effected on via one of the other two switches Different setting method for the machine, so that this one product from one of the two groups only after entering a coin of the higher category would therefore consist of putting the third switch in its second position and the first switch to its second position, so that the entry of a coin of a lower category is prevented. Is located the third switch in its second position and the first switch in its first position so will through the input of a coin of the higher category only the first relay is energized and the subsequent entry of a coin of the lower category, which had been prevented until then, causes an excitation of the second relay,

The device may include a first blocking relay that is normally energized and then accepting a coin lower Category allowed by the machine, jaLoeh im .entregten State blocks the passage for coins of the lower category and thereby prevents their acceptance, whereby the switching device has a fourth switch, which is located between the first blocking relay and a switch located on the first relay is switched on in series. This fourth switch has a first position in which it bridges the changeover switch, and a second position, in which a connection via the changeover switch and the fourth switch to the first blocking relay is established in the energized state of the first relay, and a third position in which a connection via the changeover switch and the fourth switch is made to the first blocking relay when the erete relay is de-energized is located.

The device may have a second blocking relay which is normally energized and then accepting a coin higher Category by the device allows, but in the de-excited

809809/00 8 6

State blocks the passage for coins of higher category and therefore prevents their adoption. This second blocking relay is parallel to the first blocking relay, the fourth switch and switched to the changeover switch, the two blocking relays in lending to the normally closed contacts on the second relay, which open after energizing the second relay and interrupt the connection to the blocking relay.

The device can have a fifth switch with three switch positions contain, which act in the manner described below:

1. The first position in which the device operates in the manner described above.

2. The second position related to the fourth switch in its first position and the third in its second position Switch is used so that when a coin of a higher category is entered, none of the setting relays but the first blocking relay is energized, so that after entering a coin of a lower category, both setting relays get excited.

3i The third position, which in connection with the in its third position located fourth switch ▼ is used, so that according to the for the first three Switch made arrangement either:

a) is operated, the first one part of the relay is de-energized and the first blocking relay and thus the path for the coin lower category is blocked TXSS & energized the "wide blocking relay, thereby Hisga & d of a coin of a higher category possible

so that both setting relays are actuated, _etc.

or b_) None of the setting relays is actuated, but at / 6locking relay are energized, so that after entering a coin the higher or lower Category the associated setting relays are working.

It should be noted that the word "group" that is used here with regard to the available goods, can also mean that only one goods is understood will. This word is used for convenience to indicate that at least one commodity belongs to one of one or more other goods different price can be sold.

The invention is described below, for example, with reference to the accompanying drawings, in which:

In the upper half of the device is a cooled milk tank 18 attached · This Miloh is used when dispensing tea, while dry milk is used for coffee. This arrangement was taken because, in general, coffee with a higher mileage is preferred than tea and because it is cheaper, to add this higher milk content in solid form than to dispense a larger amount of liquid milk for coffee than for tea The latter would also result in a corresponding reduction in the volume of water bring with you. A valve similar to the hot water valve is located on the underside of the milk tank Excitation of a solenoid is opened for a predetermined time if the machine is put into operation. the

A coin insertion slot located on the front of the device is aligned with a slot in which the inserted coin falls down to a coin selection mechanism that controls the Subjects the coin to the usual tests and accepts or rejects them. The selection mechanism is constructed in a known manner and checks two different coins, for example one Penny piece and a three-penny piece, a three-penny piece and a

809809/0086

Sachs-penny 8 tuck or one penny and one six-penny. The operation of the device is first under the assumption described that there is a selection device for a one-penny piece and a three-penny piece. Just below that The point at which the coins take different paths as they pass through the selection mechanism are two coin blocking relays arranged, one for the coin of higher category (coin value) and the other for the coin of lower Category is determined. These blocking relays are illustrated in the figure by relays BH and BL. The relays are normally energized so that a coin can go through the selection mechanism. However, if the relays are de-energized, the Anchors in the way of the coins and prevents them from passing through * The held coins can be returned by pressing a return button on the front of the machine get back again. There are spring-loaded switches for the coins at the lower ends of the two coin paths higher and lower categories, which are illustrated in FIG. 2 by CSH and CSL, respectively.

These individual sales prices are explained separately below

(a) By entering a penny, if this is accepted by the selection mechanism, OSL is activated and the Beiais ILI is activated. The contacts TLl / i close so that the excitation of the relay is maintained when OSL returns to its original position after the penny has passed. The relay IL2 is excited via the contacts IL1 / 2 when GSL returns to its original position and this relay maintains its excitation via IL2 / 1. IL2 / 2 closes and since SW.B is in position 3, relay E is excited, after which E / l maintains this excitation

809809/00 86

and IL1 de-energizes, while E / 2 closes and E / 3 de-energizes the blocking relays and energizes the relay SU, E and SU are the two aforementioned setting relays, both energized and, as explained below, allow either tea or Coffee can be removed from the device by the operator.

Since the two blocking relays are now de-energized, none other coins accepted

If a three-penny is entered instead of a penny, it is easy to see that the relay E and consequently also the relay SU are energized directly. This also applies to the following explained settings (b) and (f) where at least one drink is received for a penny or two pennies can be. Therefore, if a person does not have the necessary number of pennies, he can get the desired drink afterwards Entry of a three-penny piece received. Bach completed the sales process the relays SU, E, 111 and IL2 are de-energized by the switch-off cam DC 2 and the blocking relays are energized again.

(b) Since SW.B. is in position 1, SU is excited by means of relays IL1 and IL2. E is not energized, so that, as will be explained below, only tea is now being dispensed by the device. Since E is not energized and SW.0 is in position ^f 1, none of the blocking relays is de-energized, so another penny is thrown in can be. Since the switch IL2 / 3 was previously actuated, the heater E is excited via the SW.A, SU that have remained excited. The blocking relays are now de-energized.

(o) By entering a penny, SW.b. SU excited and there if SW.O · is in position 3, actuation of SU / 1 deenergizes BL, which means that another Pennys are prevented. Optionally, a three-penny can be entered, whereby both E and SU are excited.

809809/0086

(d) By throwing in a penny, SU is excited via SW.B and since SW.O is in position 3, pressing SU / 1 a de-excitation of BL is carried out, whereby the acceptance of another penny is prevented. Since SW.E is in position 3, If you press IL.i / 3, BH and by throwing in a 3dy piece, the relay E is energized while SU remains excited »

(e) Because of the SW.B. which is in position 2, ie in the "OFF" position. therefore, neither SU nor E is excited by the introduction of a penny, but IL1 and IL2 are excited as before. SW.A is in position 1, which means that when a second coin is inserted, E (and also SU) over SW.A. is excited ₀

(f) The SW.b. which is in its "OFF" position. prevented an excitement of S or E after a first Pennystüek has been inserted, during the SW.A in position 3 causes SU to be excited after a second penny has been thrown in, after which BL is de-excited. Optionally, by entering of a 3d piece excited both E and SU

(g) SW.B. in its "OFF" position prevents SU or E from being excited after entering a first penny, while after Throwing in a second piece of penny through the SW, A in position 3. SU is excited and BL is de-excited »The one in the position 3 located SW.E. after entering the first penny the excitation of BH, so that / probably SU as well as E are excited, if a 3d piece is thrown in,

(h) SW.D, is in position 2, whereby the one in position 1 received influence on the input of coins with high and low Value is reversed. By throwing in a 3d piece, IL1, IL2 and B (and SU) are excited via SW.B. SW.O. is in position 2, so a penny is not accepted will.

8 0 9 809/0086

(i) Since SW.C. is in position 2, one penny can still be not be accepted. By throwing in a 3d piece, STJ is excited via SW.B and because of SU / 1 a penny is now accepted (which may have been thrown in before the 3d piece and held by BL), causing E to be excited directly. at With this arrangement, the higher price is achieved by adding a penny and a three-penny piece.

(3) The link between SW “C. and Bl is interrupted so that BL is permanently de-energized, regardless of the position of SW.0 .. A penny is therefore not accepted at any stage of the operation. By inserting a three-penny stick, STI is transmitted via SW.B. excited, while a second three-penny piece E excited via SW.A.

(k) If SW.E. in position 1 and SW.D. are in position 2 and the three-penny is thrown in first, becomes none Setting relay actuated, but there is an excitation of

BL through IL1 / 3 »so that when a penny is inserted, both STI as well as E are excited.

(1) The link between SW.C. and BL is interrupted, which means that the position of SW.C. B1 permanently disconnected and no penny is accepted at any stage of the operation. The SW.B. which is in the "OFF" position prevents arousal by SU or E after throwing in a first Drexpenny piece, while IL1 and IL2 are excited. Since SW.A is in position ^ takes place after throwing in a second Ireipenny piece via SW.A. an excitement of E and SU "

As can be seen from FIGS. 3, 4 and 5 of the circuit diagram, the various Sehalter control the operation of the following Motors and solenoid valves: TM1 cup tower motor, cup dispenser motor 0M1, water pump motor PM, water discharge solenoid valve SV1, Water flush valve SV2, motor MM for the dry milk canister, motor 0M2 for the coffee canister, motor TM2 for the tea canister, Motor SM for the sugar canister, the counter TC2 for the determination the dispensed tea cups and the fresh milk valve MoV. The switches SW1, SW2, SW3, SW4 and SW5 in Figure 3 are turned on Press the appropriate selection pushbuttons on the front of the

809809/008

the machine closed. From these switches / relays A, B, G, D1 and D2 controlled If none of the relays STJ and E was energized as a result of the coin amount entered into the machine, then closing these switches does not cause any excitation one of these relays.

Assuming that a sufficient quantity of coins had been inserted to energize the relays SU and Ά so that their contacts SU / 2 and E / 2 close, the following will consider the effects of closing the aforementioned switches result:

When SW1 closes, relay B is energized, which adh the contacts B / 1 feed the sugar canister motor SM energy, if the Sohalter GS 16 does this during a through the cam switch GS4 controlled time allowed, whereby the contacts B / 2 maintain the excitation of the relay after the release of SW1 and B / 3 energize relay A. A / 1 actuates the tower motor TM1 via the switch TS, the cup dispensing motor GM1, the Pump motor PM via the switch SW1O and the solenoid valve SY1O via switch SW1O, while contact A / 2 relays A holds in an excited state. The contact D1 / 1 remains in the position shown and the coffee canister motor CM2 is therefore operated via the CSH holder. It becomes black coffee [given with sugar.

When switch SW2 is closed, relay C is energized and kept excited via contact G / 2. The contact G / 1 is closed, the dry milk canister motor MM via the Sohalter GS 13 is actuated while contact G / 1 is the relay A excited, which exerts the influence mentioned above. This way, white coffee is dispensed without sugar.

When switch SW 3 is closed, relays G and B are energized

809809/0086

and consequently relay A is also energized. ^I t is thus given sweetened white coffee.

By closing the switch SW4, the relays D1 and D2 and the relay B are energized via the open switch SW5. Contact B / 3 energizes relay A and ¹ D2 / 2 energizes relay 0. D1 / 3 maintains energization of relays D1 and D2 while D2 / 1 opens and prevents any more coins from being inserted when the Sales process has started once, whereby D1 / 1 opens the circuit for coffee and dry milk and closes the circuit for tea and fresh milk. The switches SW1, SW2, SW3, SW4 are designed as three-pole switches, so that even if the switches SW1, SW2 or SW3 are pressed after the switch SW4, D1 / 1 does not return to its original position, so that it is impossible to select a To obtain a mixture of tea and Ifeffee »In this way the motors TM1, CM1, PM, TM2 and SM as well as the valves SV1 and MV are operated '. The fresh milk valve MV is opened during the time specified by the cam switch 0S6 and a contact D2 / 3, which actuates the tea counter TC2, activates the flushing valve SV2 during the time specified by the cam ehalt er 0S5 after the milk valve MV is closed. By closing the so holder SW4, tea with fresh milk and sugar is dispensed.

By closing the switch SW5, the relays DT and D2 energized, which in turn energize the relay 0, so that the relay A is energized and the blocking relays BH and BIi are de-energized. Closing switch SW5 results in tea with fresh milk, however sugar-free.

If the coins introduced into the device are only sufficient to energize the relay SU, then the switch is closed by closing the bottom SW1, SW2 or SW3 none of the ERelals energized, since the switches are in series with the contact E / 2, which opens, like this

80 980 9/0 08 6

that no coffee is obtained. The switches SW4 and SW5 are parallel to E / 2 and since SU / 2 is closed, when actuated one of these two tea switches dispensed in the same way as previously described.

If SW1 , SW2 or SW3 were closed in order to select coffee as the beverage to be dispensed, then the opening contacts A / 3 prevent subsequent energization of the relays D1 and D2 after the switch SW4 or SW5 _f closes so that the contact D1 / 1 in the remains in the position shown in the drawings and the contact D2 / 3 remains open.

When the sales process is finished, the shut-off cam is operated 02 the changeover switches CS1, CS3 and CS12, so that the power supply for the selection, setting and output circuits is interrupted at the same time and also a total quantity counter TC and, if tea has been dispensed, a tea counter T02 is actuated. It can thus show the total number of tea or Coffee mugs are determined.

When the cups in the machine are exhausted, an "empty" switch ESW is actuated, which de-energizes the blocking relays BH and BL, so that further coins are prevented and an "ATISVEBKAIJiT" warning lamp X2 lights up.
