Description

"CIRCUIT AND CONTROL METHOD FOR DISPENSING EQUIPMENT, AND MAGNETIC SENSOR FOR GAUGE"

Field of the Invention

The present invention relates to a method and circuit for the control of equipment for carbonated beverage, coffee, teas and / or juices dispensers, coconut water, natural guarana, ice, ice cream, frozen and iced confectionery and açai. a liquid dispensing equipment equipped with this circuit. The circuit is capable of locally and remotely controlling and reporting possible equipment failures and shortages, such as: gas, syrup, coffee, tea and / or juice and water; thereby reducing logistical costs, customer dissatisfaction and lost sales from equipment malfunction. The present invention further relates to a magnetic sensor adapted for use in pressure gauges and a capacitive sensor for use in product supply elements within such dispensing equipment.

State of the Art

The present invention may be applied to any type of dispensing equipment. It is interesting, for a better understanding of the prior art description, to briefly summarize the operation of the post mix system. Such a system is present in equipment for dispensing liquids and carbonated products. These products are usually made up of a mixture of three components: H ₂ O (water), syrup and CO ₂ (carbon dioxide). The carbonator present in the post mix equipment mixes H ₂ O and CO ₂ , forming carbonated water which is then mixed with the syrup by an outlet nozzle (or mixing valve) also present in the equipment.

Current post mix equipment reading for CO ₂ gas is visually obtained by an operator through the pressure gauge. The gas cylinder can only be changed when the gauge indicator if in the red band. With respect to syrup, only when the syrup liquid container is partially empty will the system operator visually change the syrup.

As for the counting of cups that are dispensed by the equipment, there is no accurate information. Only an estimate is made with a ratio of the amount of syrup in the container versus the size of the cup used. Regarding the temperature sensor, maintenance only happens when the equipment stops cooling properly, within the pre-established range.

A common shortcoming with this equipment is that the lack of any of the products is only detected locally after the fault occurs.

In the case of post mix equipment, in particular, the lack of CO ₂ gas will require the replacement of the cylinder containing it. This change, however, only occurs after the pressure gauge pointer has moved to the red band beyond its minimum reserve. As a result, the machine holding facility should call upon the machine supplier's service to remove air from the piping and to return the equipment to normal operation. Before this intervention occurs, the product is served only with syrup and without CO ₂ gas.

The lack of C0 ₂ gas is also only noticed after some use of the machine by a number of customers, when only the syrup with water is dispensed. This undermines the beverage quality and corporate image, leading to increased operating costs for the beverage supplier, which has to move a team to remove air from the pipeline.

In turn, when syrup shortages occur, the equipment continues to dispense the product with carbonated water only. Only in this situation will the operator verify that the exchange of the corresponding container is required.

In addition, as the precise number of cups dispensed by the equipment is not determinable, there is a certain rejection by the point of sale owners to purchase such equipment. post mix equipment, precisely because of its inaccuracy in quantifying how many cups the equipment dispensed. This further increases the possibility of fraud by employees of these establishments.

Regarding the temperature sensor (thermostat), because there is no control of this sensor, it can interfere with the quality of the dispensed product if it is working improperly.

For the lack of water, there is no device in the equipment that provides this information, which may cause the dispensed product to be served only with the syrup liquid, as well as generate air in the pipe and cause problems such as related to the lack of CO2 gas.

All these failures, besides affecting the correct functioning of dispensing equipment, also affect the image of the seller himself and the company that manufactures the products.

Thus, from the state of the art, no relevant antecedents were found that compromise the patentability of the device and the method of dosing carbonated drinks.

Thus, from the state of the art, no relevant antecedents were found that compromise the patentability of the device and the coffee dosing method.

Thus, from the state of the art, no relevant antecedents were found that compromise the patentability of the device and method of dosing teas, such as mate, and / or juices.

Thus, from the state of the art, no relevant antecedents were found that compromise the patentability of the device and the method of dosing coconut water.

Summary of the Invention

The present invention notably aims to avoid the drawbacks of the above described issues by providing the following solutions: - a magnetic sensor which may, for example, be added to a pressure gauge of a C0 ₂ gas cylinder to detect gas shortages;

- a capacitive sensor which may, for example, be connected to a syrup-carrying hose or a water-carrying hose for detecting the lack of such a product; and

- A control circuit connected to all sensors to effectively manage the operation of all these elements.

In accordance with the present invention, there may further be a temperature sensor for monitoring temperature variation to improve the efficiency of the temperature system control, an audible and / or visual alarm connected to the machine sensors for fault signaling, and a remote signaling unit to alert a remote device of equipment failure.

It is an additional object the application of the proposed solutions in carbonated beverage dispensing equipment.

It is an additional object the application of the proposed solutions in coffee dispensing equipment.

It is an additional object the application of the proposed solutions in tea and / or juice dispensing equipment.

It is an additional object to apply the proposed solutions in coconut water dispensing equipment.

It is an additional object the application of the proposed solutions in natural guarana dispensing equipment.

It is an additional object to apply the proposed solutions in ice dispensing equipment.

It is an additional object the application of the proposed solutions in ice cream, frozen and frozen confectionery equipment.

It is an additional object the application of the proposed solutions in acai dispensing equipment.

In a can dispenser equipment, for example, the control circuit will control a can presence sensor and trigger some sort of alarm in case of failure.

As an example, in the particular case of post mix equipment, the CO2 gas shortage detection process starts with the activation of the CO2 shortage sensor. This generates a signal, sent by the sensor to the control circuit, which in turn processes this information, blocking the equipment from supplying any other type of product. The audible and / or visual alarm signaling the point-of-sale operator about the need to change the CO2 gas cylinder can then be triggered and the failure reported to a management computer center via wired or wireless communication. wireless, such as GPRS / GSM / SMS, which in turn can trigger a text message to pre-registered cell phones on this exchange about the need for maintenance. The same goes for the other sensors, if present.

In a preferred embodiment, the control circuit further comprises means for dispensing traceability, such as a GPS.

For the particular water shortage situation, the sensor also sends a signal to the control circuit. With this, the control circuit processes the information and may disable the dispensing of all products. The same applies to the syrup sensor if present. Upon receiving a signal from this sensor, the control circuit can lock the actuation button on a particular syrup container, releasing the others for normal use. This would avoid wasting water and gas.

Brief Description of the Figures

The invention will now be described with reference to the accompanying drawings, in which:

Figure 1 illustrates a post mix device;

Figure 2 illustrates a gas cylinder with a pressure gauge containing a magnetic sensor according to the present invention;

Figure 3 illustrates a hose connected to a capacitive sensor according to the present invention; Figure 4 illustrates a control circuit constructed in accordance with the present invention.

Detailed Description of the Invention

The examples described herein should be construed as illustrative rather than restrictive.

It should be noted that all objects of the present invention can be applied to all types of beverages, in particular:

- carbonated drinks;

- coffee;

- teas and juices;

- coconut water;

- natural guarana;

- ice;

- ice cream, frozen confectionery,

- Acai;

Figure 1 illustrates a post mix 1 device and its following components:

a water hose 10 connected to the capacitive water shortage sensor 11;

- a CO ₂ cylinder 20 with a pressure gauge 22;

a carbonator 30 connected to the water hose 10 and the CO ₂ cylinder 20;

- two syrup pouches 40, 50, with two capacitive syrup lack sensors 31, 41; and

a liquid dispensing unit 60 which, in addition to dispensing liquid, also mixes the syrup with carbonated water from the carbonator 30.

The magnetic sensor of the present invention

The magnetic sensor of the present invention is illustrated in figure 2. It can be fitted to pressure gauges without resulting in changes in operating characteristics and without modifying their original formats. Such a sensor is comprised of an auto switch 21 preferably positioned within the pressure gauge 22. Auto switches are non-contact proximity devices utilizing inductance, Hall effect principles and variable reluctance or resistive magnet technology. They detect magnetic objects and are usually used to trigger a switching process. Any auto switch found in the prior art may be used for the purposes of the present invention.

As the detector 21 is triggered by the presence of some magnetic field, the pressure gauge pointer 24 itself is part of the magnetic sensor of the present invention and may be magnetized or may have a magnet connected to it.

If applied to a CO2 cylinder pressure gauge, the auto switch will detect the lack of CO2 as the pointer 24 reaches the red gas out indication range. For this purpose, the auto switch 21 should be positioned somewhere within this range, inside the pressure gauge, or even on its front face, in which case it should be located adjacent to the final position of the pointer 24. Once the presence of a field is detected magnetic, the sensor will emit a signal.

When applied to a CO2 cylinder pressure gauge and used in conjunction with the control circuit of the present invention, this signal is received at an input of that circuit. The circuit will then process this information and issue orders to block dispensing equipment 1, disrupting the supply of products. The control circuit output for this lockout may, for example, be serially connected to the carbonator power supply neutral 30 and the source power supply (not shown) that feeds the mixing valves of the liquid dispensing unit 60.

In additional configurations, the sensor can be adapted and applied to equipment to measure presence and allow coffee dispensing.

In additional configurations the sensor can be adapted and applied in equipment for measuring presence and allowing dispensing of teas, such as mate tea, and / or juices.

In additional configurations, the sensor can be adapted and applied to equipment to measure the presence and allow the dispensing of coconut water.

In additional configurations, the sensor can be adapted and applied to equipment to measure presence and allow ice dispensing.

In additional configurations, the sensor can be adapted and applied to equipment to measure presence and allow dispensing of ice cream, frozen and / or frozen confectionery.

In additional configurations, the sensor can be adapted and applied to equipment to measure presence and allow the dispensing of acai.

The capacitive sensor of the present invention

The capacitive sensor of the present invention is illustrated in Figure 3. It is a capacitive sensor with a housing and can be attached to a hose 81. The capacitive sensor consists of a potentiometer 82 and a capacitive detector 84. Potentiometer 82 serves to adjust capacitance values by the presence or absence of fluid inside the hose 81. Capacitive detectors are devices capable of non-contact measurement that varies with the situation and / or position change of a conductive target. For this, they use capacitance which is a property that exists between two conductive surfaces. Any change between these surfaces will result in a change in the measured capacitance. As with the magnetic sensor, any capacitive detector found in the prior art may be used for the purposes of the present invention.

Thus, the sensor operation will vary depending on the presence or absence of fluids inside the hose. The capacitive sensor can, for example, be set to send a signal when no fluid inside the hose.

In an optional configuration, the sensor can be adapted and applied to equipment to measure presence and allow dispensing of carbonated drinks.

In additional configurations, the sensor can be adapted and applied to equipment to measure presence and allow dispensing of teas, such as mate tea, and / or juices.

An example of fixing this sensor is illustrated in the same figure 3. A frame 83 fixes potentiometer 82 and capacitive detector 84 to hose 81, with the aid of nuts and washers to hold these elements together.

In a particular embodiment, the capacitive sensor may be applied to the hose carrying the syrup from its container 40, 50 to the liquid dispensing unit 60. In that case, in the absence of syrup, the sensor is triggered by sending a signal to another inlet of the syrup. control circuit. The control circuit will process this signal and block the triggering of particular container. If other containers are present and not yet empty, syrups will continue to leave their interiors normally.

In another particular embodiment, the same capacitive sensor may be applied to the hose 10 which carries water to the carbonator 30. The operation is the same as a function of the presence or absence of water within the hose. In the event of a water shortage, the sensor will send a signal to a control circuit input, which in turn will process this information and disable the dispensing of all products.

The same source connection used in the case of the auto switch can also be used here to block the operation of the respective components.

The control circuit of the present invention

Figure 4 illustrates the control circuit of the present invention connected to a power supply 79. This circuit has several inputs 71 responsible for receiving the signal from at least one sensor and outputs 72 responsible for sending orders to the dispensing equipment. after processing the input signals in a processor 70.

The circuit of the present invention comprises:

at least one input for receiving signals from at least one sensor that measures the operating conditions of a component of dispensing equipment;

In this case it comprises at least one sensor being formed by one or more sensors selected from: coconut water shortage sensor associated with the coconut water inlet of the dispensing equipment; liquid temperature sensor; and cup presence sensor.

In an additional configuration, the circuit can be adapted and applied to equipment to control natural guarana dispensing.

In this case it comprises at least one sensor being formed by one or more sensors selected from: acai lack sensor associated with the acai input of the dispensing equipment; liquid temperature sensor; and cup presence sensor.

In a preferred embodiment, this circuit is connected to a modem 80 via an interface 74 for sending real-time information about the dispensing equipment to another remote device such as a central office. The currently known GPRS / GSM / SMS technology can be used for this purpose. Thus, for example, the need for maintenance of dispensing equipment, such as changing a gas cylinder or syrup container, can be remotely alerted. The warning can also be glimpsed through messages to mobile phones registered in the system. A USB, serial, Ethernet and / or Internet communication interface, as well as traceability means such as a GPS module, may also be present for the same purposes.

Thus, the maintenance companies of these equipments would have advance notice of the need for scheduled replacement of certain parts. The exchange of information with the logistics operators is a differential of the control system, because at any moment the operator will have the necessary information regarding the real situation of the equipment, whether its operation or supply.

In another particular embodiment, modem 80 may inform the position of the dispensing equipment on the globe. Because this equipment is leased by the supplier company, the system would be used to curb diversion of this equipment.

In a further particular embodiment, an input 75 for a keyboard may be provided in the control circuit for defining operating parameters, for determining the products to be dispensed with, and even for obtaining information that the circuit may provide. Additionally, a display 76 may be provided to facilitate operator interface with the circuit.

In another particular embodiment, the control circuit is connected to a visual and / or audible alarm 73 that will alert locally to the failure detected by either sensor. The local alert can be perfectly done concurrently with the remote alert.

In another particular embodiment, the control circuit has an interface 77 for interconnecting major payment means such as credit and debit cards, currency, tokens, smart card and mobile debit.

Again, the present invention is not exclusively related to post mix equipment. The same control circuit, for example, can easily be added to current vending machines without the need for heavy investment in converting them. The control circuit can also be used in vertical and horizontal freezers using the circuit for maintenance control, global positioning of the equipment and inventory control thus avoiding theft and diversion thereof. In addition to the sensors described above, the following sensors may be present in dispensing equipment, all equally controlled by the control circuit:

- power failure sensor;

- temperature control sensor - a thermocouple sensor already known in the prior art can be used, for example. In this case, only the information of the voltage variation of the thermocouple voltage will be monitored;

- sensor by product (can, bottle, cookies, etc.) with partial or total blockage of the machine;

- cup presence sensor - can be, for example, a photo sensor positioned on the tray where the product dispensing cup is placed. In this situation, when the cup is placed in the product selection tray, it activates the photo sensor that sends a signal to the control circuit to control the release of the products;

- counter and totalizer for cups sold by flavor, ie syrup. This accounting can be done, for example, by a program inserted in the control circuit itself. In this case, it is just a simple counter, which increases as the cups are dispensed. The circuit can also be programmed to inform the user and the system, when it reaches a certain number of dispensed cups, about the need to exchange a particular product. The cup count can also be shown on the display when present, connected to the control circuit or sent remotely by the modem when present.
