Device for dispensing fluids

The invention relates to a device for dispensing Fluids, especially liquids, in particular to a device operated by money or money substitute, in which a quantity of fluid to be dispensed is carried out by the introduction of a predetermined number of coins and / or notes is preselected, thereby providing indication signals which are stored by counters until fluid delivery is initiated. The counters count then from the stored total information downwards until the stored output signals which correspond to the match the total amount of fluid to be dispensed, have been dispensed, whereupon the dispensing process ends will. The device according to the invention also contains a accelerated impulse device, which uses a fluid

For numerous reasons, mainly to save money Personnel costs and to create a self-service option, it is desirable to set up petrol pumps in such a way that that they can dispense a preselected volume of fuel, which can then be taken directly from the ignition. the Multiple pumps can then be preset from a remote one Place to be monitored by a single operator, who first of all the desired fuel quantities takes the appropriate amount of money and then adjusts a control panel so that exactly the amount of fuel chosen which delivers the desired pump.

Another possibility is that pumps are provided with additional devices, which are thrown in Accept and add coins and banknotes, which will preset the pump to deliver a certain amount of fuel which corresponds to the amount of money thrown in. Such coin-operated machines become common set up in gas stations in which there are no operators, so the gas station Sag and

Although coin-operated machines are widely used for this purpose, they are subject to certain dangers, particularly as a result of criminal acts through which the coin boxes are destroyed and robbed, or by using various types of cash to get an unlimited amount of gasoline from the pump for an insignificant one Referring to the amount of money. The associated risks of coin-operated machines similar to the installation have in many cases led to such facilities was refrained from setting up or already established plants were abandoned.

Since gradations of five cents are common for the pulsed counters in coin-operated gas stations are sufficient, unlimited amounts of petrol will be withdrawn after the insertion of a to initiate petrol delivery sufficient small amount of money often the following " be crügeriscaer trick atigewtiuuei /: The pump wiru xu G-aug until she has dispensed four cents of gasoline, which is insufficient to run the To start the counter.

To make this frequently used procedure ineffective, a circuit is provided according to the invention which a collection of the money at a rate of about a dollar in five seconds, and this Monetary collection continues as long as it is the pump switch lever is in the "off" position. Since the electrical reset device has a noticeable Time needed to close the pump again, at least 50 gents are lost if the switch is turned off will. If the switch remains in the off position for a noticeable period of time, the entire in the petrol station collects deposited money, and if the deposited money is incomplete when it is handed over is used up, no more money will be accepted until the money is completely used up.

The device according to the invention essentially contains a circuit for automatically dispensing a predetermined Amount of liquid 'corresponding to an amount introduced on banknotes, coins or the like, in particular a pulse generator operated by coins and banknotes, its impulses depending on the particular application

The operation of this device will now be described with reference to FIG the circuit diagram of Pig.2 explains what different optional operating modes are described which show the versatility of the device.

The controller includes a first, unidirectional step counter 42, which in the present Pail one commercially available under the name Keinemann step switch A well-known device is that at ten lapulsen a complete Makes revolution, but this is modified by installing two magnets 44 and 46. As a result of the 3 installation of magnets 44 and 46, the step counter has a cycle of five pulses, which are assigned gradations of 5 cents each,

As can be seen from the total capacity of the two provided 'pedometers, a maximum amount of money from $ 4 and 75 gents inserted into the control unit will; Obviously, additional ones can be used Counters can be provided to increase this amount, or to allow adaptation to other monetary systems. In addition, the slider 30 allows the use of dollar bills up to a total of 4 dollars, after which three additional quarter dollar pieces can be thrown in, so that the device capacity of the machine is achieved. Obviously, any number of various coins and bills can be used in the system be used; the division into 25 gents and 5 gents was chosen because this results in a total amount, which according to US norms normally results in an almost full gas tank.

It should be noted that for the operation of the described a establishment of a combination of dollar bills and quarter, dollar pieces can be used so that it is possible to put three quarter dollar pieces in and then this Coins are followed by four one dollar bills, making one

Total amount of four dollars and 75 cents is reached. As previously mentioned, the dollar bill acceptor is designed to have four pulses per dollar generated so that a total of 19 IRA pulses by using from four one dollar bills and three quarter dollar pieces can be obtained. Obviously, with that Half-dollar pieces can also be used, which then generate two pulses in the coin mechanism.

The coil 72 is excited via a triac 78, which in.dem connected to ground branch of the coil circuit, and a trip diode 82 for the triac 78 is over biased a 10,000 ohm resistor 84 so that the triac carries current. For this purpose, a circuit is created from the hot line 8β via the normally closed contact 88, 90 of the relay S2 and formed via the resistor 84 to the diode, so that the excitation circuit for the S ^ uIe simply from the hot line 86 via the coil 72, the triac 78 SU of the ground line 80. That Money is returned when the relay 92 responds, since the normally closed contact 88, 90 then opens; further will the money is returned when the maximum amount switch is closed and the bias on diode 82 via the 100 ohm resistor 94 to the ground line 80 short-circuited. The result of closing the switch

resulting

resulting direct IC _& rzschluo3 simply takes the opening voltage for the Sria'c 78 from the diode 82 off. Since, as will be shown, the relay 92 responds when the pump switch 96 is closed, the money is returned when the pump switch is closed.

When the relays 92 and 98 are open, the upper additive coil 99 of the step counter 60 at a Grleich- - voltage of 27 volts, the 'ä via a 200 ohm resistor 102 from the 48 volt DC voltage source is obtained. The insertion of a quarter dollar piece into the coin slot 32 briefly closes the switch 70, as a result of which a direct voltage of 48 volts is briefly applied to the lower additive coil 104 of the step counter 60. The consequence of this is that the step counter 60 is rotated in an additive direction over 18 °, although this effect actually takes place in two steps of 9 °, namely one step when the DC voltage pulse of 48 volts is applied, and in a further step, "when this pulse stops. The incremental, pulse-wise incrementing of the step counter 60 takes place in that a 48-volt pulse outweighs the 27-volt bias in the upper winding 99, which means that a positive voltage is alternately applied to the upper winding 99 and to the lower winding 104 is equivalent.

Throwing in a quarter dollar piece thus causes an additive step of the step counter 60 and causes the switch 66 to open, since the magnet 62 is moved away from this switch as a result of the first itapulse step. The opening of the switch 66 interrupts enes short circuit from the gate electrode 108 of the triac 110 practicing 100 Ohm-Y / esistance 106 to ground so that the gate electrode 108 from the high voltage of the heissea line 86 over the 10,000 Oha-V / esistance 112 biased will. The triac 110 is thus energized and energizes the relay 114, the excitation circuit running from the hot line 86 via the relay winding 114 and the triac 110 to the cash register line 80.

The relay 114 is always energized as long as there is money in the system, and it closes the normally open contact 116, 113 when it is energized, whereby the reset motor 120 is connected to voltage, so that the reset process, by which the arithmetic unit of the pump is reset to zero will take place. The actual reset process begins when the pump switch lever (not shown) is in the ^; 'Position "on" is moved, and after a few seconds, the P _u mpenschalter 96 closed, thereby indicating the end of the reset cycle. It is important to note that switch 96 does not close immediately

is when the / Pucap switch lever is in the "On" position is moved because the reset process takes several seconds needed, but that the Puapenschalter 96 immediately opens when the pucap switch lever is in the "Off" position is moved.

When the tampon switch 96 · by the return motor 120 has been closed, the relay 98 is energized directly, the Strota circuit from the 'hot & en line 86 via the Switch 95 and the winding of relay 98 to ground line SO goes.

The normally open contact 126, 128 of the relay 98, which is also closed when this relay is energized, energizes the relay 92. The relay 92 changes the state of the step counter 60 from the additive to the subtractive (counting by opening the normally closed contact 130, 132 and through Closing of the working contact 132, 134. Perner closes the working contact 136, 158 to form a solenoid holding circuit, so that the relay 92 is kept energized via the working contact 140, 142 of the relay 114 as long as there is money in the system.

When switch S6 closes, the pump motor runs 144 on, and the control coil I46 of the "electromagnetic The valve is energized via the triac 143, causing the electromagnetic valve (not shown) in the tap is opened. The triac 178 receives its bias in a similar way to the triacs and 110 described above, as long as the switch 52 of the step counter 42 is open.

The step counter 42 counts 5 cent pulses and subtracts 25 cents from the step counter 60 via the transistor circuit 156 each time the count on the counter 42 has moved from Kuli to J2Q.Ceats. The transistor 156 excites the lower subtractive winding 158 of the step counter 60 in pulses, whereby it applies a DC voltage of 48 volts only briefly when the capacitor 160 is charged, even if the transfer magnet tongue 56 remains closed for a long time. It is not allowed to leave 48 volts on this winding for more than a second or two. After the switch has opened 56, the K _o adensator discharges 160 across the shunt resistor 162 68 000 ohms.

After the money has been inserted, the closing of the pump switch 96 causes the relay 98 to respond, which in turn energizes the relay. The relay 92 has a self-holding circuit via its own make contact 136, 138 and via the make contact 140 _f 142 of the relay 114, as long as money remains in the system. If the pump switch is opened while there is still money, it must be viewed as an abnormal operating condition resulting in relay 98 dropping while relay 92 remains energized.

Circuit 162 employs a conventional setup in which a capacitor is slowly charged through a diode 172 and a 22,000 ohm resistor 174 '. When the capacitor has been charged to a voltage of about 3 volts , a Durciibrucha diode 176 is ignited, ao that a magnet switch 178 is actuated in a pulsed manner by energizing a winding 180 . The capacitor 170 discharges , and when the current in the coil 180 falls below a certain value of, for example, 5 milliamperes, the diode 176 is loosened again, so that the charging of the capacitor begins again can be achieved. Usually a speed of about four pulses per second is set, but it can be increased, if desired, up to about 10 pulses per second; the pulse repetition rate is limited only by the time required to operate the step counter 42.

Since the Relate 9B has fallen, the Impulse Sriac is 50 out of operation, because the normally open contact 122, 124 of this relay is open, so that the step switch 42 itself can then be actuated when the magnetic switch is accidentally closed. The direct activation of the Magnetic switch 178 between step counter 60 and ground line 80 produces a pulse train which simulates the delivery of gasoline, and the collection of the money takes place at great speed,
