Definitions

  • the invention relates to a system for the safe preparation of on demand packages of liquid products, said system being intended to dose and dispense a predetermined quantity of a liquid product from one or more tanks into a container, said system comprising:
  • a first drawback consists in the fact that the current management of the unique identification codes of the tanks and product containers does not allow an adequate level of security against actions of unauthorized reuse and compliant with the rules of tanks and product containers and does not guarantee that at least certain types of products can be dispensed only when requested by an operator authorized to use these products.
  • the invention aims to solve the aforementioned problems with a system for the safe preparation of packages of on demand liquid products, which has the characteristics described at the beginning and wherein the following characteristics are also provided:

  • this construction and this operating mode allow residues of said one or more components to be eliminated between one dispensing cycle and the next.
  • the aforementioned embodiment therefore also allows dispensing of fluid compounds having different and potentially mutually reactive compositions without generating danger or contamination conditions.
  • the dose of each component to be dispensed can be established on the basis of the activation time of the corresponding means for generating the fluid flow from the tank associated with the withdrawal duct and/or from the switching time in the open condition of the solenoid valve at the outlet of the corresponding duct in the mixer.
  • the feeding of the single components to the mixer through the corresponding fluid flow generating means can take place simultaneously or substantially simultaneously, since the respective quantities are detected by the activation times of the associated flow generation means and/or by the associated solenoid valves.
  • the dispensing of the single components from the single tanks to the mixer can take place in sequence, whereby the quantity of each single component is detected by the dispensed quantity measurement unit, such as a load cell that weighs the product container.
  • the dispensed quantity measurement unit such as a load cell that weighs the product container.
  • the quantity of each component for each product is stored in the product database which comprises the recipe of the corresponding product and from which the control unit defines the delivery times of the component to the mixer and/or their weight, the end of measuring the dose dispensed to the mixer and/or from this to the container.
  • an initial weighing of the product container can be carried out.
  • This initial weighing measures the weight of the container to be used as a tare for subsequent measurements of the quantity of components or of the mixed product, said value being temporarily stored in a work memory of the control unit and used for measuring the effective quantity of the various components loaded into the container according to one or more of the variants described above.
  • the load cell measures the weight of a product container which may also be partially full. From this value it is possible to determine a dispensing quantity of the product for only topping up the container, an amount which is obviously lower than the maximum quantity which can be housed in the product container.
  • the system comprises the following characteristics:
  • An embodiment which can be provided in combination with any one or more of the preceding embodiments and variants provides that a unique identification code of a product container corresponds to at least one specific product among a plurality of different products that can be dispensed by the system.

  • the system is not only able to verify compatibility between product and container and also between product composition, but it is also able to verify whether the request made by the user on the basis of its identification code is compatible with the authorization to use the product explicitly requested and/or implicitly requested through the unambiguous correlation of container identification code and type of product.
  • This check also makes it possible to memorize the dispensing events and relate them to the various users, allowing to keep track of the various operations and therefore also to verify analytically and user by user, the type of products withdrawn and the quantity per time unit of said products, for which the system allows to verify for the presence of illegal activities such as theft or other.
  • At least one or at least part or all of the means for generating the flow of a fluid in a corresponding withdrawal duct connected to a corresponding tank consist of a peristaltic pump or a vibration pump.
  • the unique identification codes can consist of optical codes, such as for instance barcodes and/or QR codes or other, while the readers are of the optical type, while the information corresponding to said codes is contained within the databases defined above and the enabling or disabling of a code must take place within the control program, setting a status of the various codes as enabled or disabled.
  • the identification codes consist of electronic tags, such as for instance RFID tags and/or beacons and/or similar devices.

  • optical codes and/or electronic tags It is possible to provide for the parallel presence of optical codes and/or electronic tags or these can be provided as an alternative to each other.
  • This information can be searched for, selected and copied from the databases present in the control unit memories and can be stored in the internal memory of the electronic tag of the corresponding product container and/or in a temporary file associated with the user's identification code and/or loaded into the memory of a portable unit used by the user and uniquely associated with the same, said unit communicating with the system control unit.
  • the mixer consists of a hopper and/or a funnel whose outlet ends with a duct and/or with a delivery mouth that can be coupled to a corresponding product container, while the individual withdrawal ducts freely flow each into said funnel or into said hopper.
  • control program contains the instructions for identifying and selecting the withdrawal duct for the solvent or diluent fluid as the withdrawal duct whose flow generating means and/or whose solenoid valve are activated last in a pre-established time sequence for dispensing at least two components of the product to be dispensed, one of which consists of said diluent or solvent.
  • An improvement may provide for dispensing the intended amount of solvent or diluent in several separate dispensing steps of a partial amount, one of said dispensing steps of the partial amount being set as the last dispensing step in the sequence of dispensing said at least two components the product one of which is the solvent or diluent.
  • An embodiment whose characteristics can be provided in combination with one or more of the previous embodiments and/or embodiment variants provides a housing for a plurality of product containers or several housings each for one of a plurality of product containers.
  • each of which can be coupled to a product container and each equipped with a dispensing solenoid valve which opens and closes the outlet of said dispensing duct, while each dispensing duct is provided with a sensor for the presence of the associated product container, each solenoid valve being associated with a predetermined container and controlled by the control unit to serve the different one or more in parallel containers inserted in the corresponding housing and connected to a dispensing duct, a load cell also being provided for each container.
  • each withdrawal duct that leads to a connection to a tank is replicated, as are the flow generation means and/or solenoid valves and these are provided in combination with a replica of the mixer and of the dispensing duct, each of said replicas being provided for a corresponding housing of a product container, a load cell also being provided for each container.
  • control program allows the machine to dispense different types of products in parallel to a container enabled to receive the corresponding product and for a user enabled to use or withdraw said product.
  • this code is made unusable, while a new operating Rfid tag will be associated with a new tank which will be delivered to the user by the manufacturer and which has been subjected to packaging by the manufacturer itself and/or by a subsidiary authorized to carry out this activity.
  • Alternative embodiments can optionally also provide for a deactivation of the Rfid tag or a similar electronic tag, while said tag will be reactivated only when the tank returns to the system manufacturer for a refill of the same and a new delivery to the user.
  • the system can therefore provide means suitable for making the electronic tags unusable or, in the case of a less radical alternative, means for enabling and disabling, i.e. turning off the electronic tags, when the codes are contained in the electronic tags, or operating via control software as described above by setting a status variable of the individual codes in the relative databases stored in the control unit as enabled status or disabled status.
  • the invention also relates to a method for the safe on request preparation of packages of liquid products, said method involving the following steps:
  • One embodiment provides for associating to each identification code of the product container, in addition to the specific type of product intended to be contained in the same, also the recipe or composition of said product, further performing the following steps:
  • An embodiment of the method provides that at least one component consists of a solvent or a diluent, a sequence of dispensing of the individual components of the product being carried out in the corresponding container, said sequence providing that at least a part of the amount of solvent or diluent is dispensed last in said dispensing sequence.
  • One embodiment of the method provides that the product container is provided with two identification codes, one relating to the container itself and the other relating to the product to be dispensed into it.
  • a further embodiment provides for a step for attributing a unique identification code to each user enabled to use the system, while the identification code of each user is correlated to a list of container identification codes and/or to a list of product identification codes for which the user is authorized to request dispensing, dispensing being prohibited when the user's identification code is not associated with the authorization to use a product container having a certain identification code and/or the use of the related product.
  • a variant embodiment provides for measuring the weight of the container to be filled with product, comparing the measured weight with a reference tare of the container and determining the residual product still present in the container by difference, while determining the quantity of topping up product is performed by subtracting the weight of product remaining in the container from the expected product weight for an empty-to-full container filling.
  • a method which can be provided in any combination or sub-combination with the previous ones, and in which after the reading step of the identification code of the tank, said identification code is disabled and is only re-enabled upon refilling at the tank manufacturer said tank with the corresponding component.
  • the identification code of the tanks is temporary and subject to authorization and rehabilitation or variation, while the identification code of the product container and/or the corresponding product are fixed and stable, being preferably said identification codes imposed in a way that cannot be modified by others than the producer himself.
  • the identification code is of an optical type such as a barcode and/or a QR code or the identification code is stored in an electronictag such as an RFID tag or the like, or the identification code is applied using in combination optical code and an electronic tag.
  • One embodiment of the method provides that the temporary identification code of each tank is constituted by an RFID tag, while the identification code of the product container and/or of the product associated therewith is of the optical type.
  • FIG 1 the same schematically shows the steps of an embodiment of the method according to the present invention.
  • the figure shows an embodiment which provides additional steps compared to an essential embodiment. These steps will be reported in the description.
  • the dispensing process is illustrated with reference to a product consisting of a single component concentrated in a single tank and which is dispensed with a pre-established dilution in a single product container referred to as a container in the figure, being mixed with a pre-established diluent.
  • the illustrated process starts from the condition wherein there is no product component tank in the system and therefore provides the steps relating to loading the tank and associating it with the system itself. Obviously these steps are performed for at least part of them only once in a while so when the tank is installed, the steps that are performed are those relating to the request for filling a container, while the installation steps of a tank will be performed only when the need arises to replace the empty tank with a full one.
  • the right branch of the figure shows the steps of the process inherent to the installation of a new tank containing one of the two components of the product to be dispensed.
  • the further component consists of the diluent which can come from a tank dedicated to the same or can also be water coming from the water mains directly or after filtration and/or accumulation in a buffer tank.
  • a new tank is loaded containing a specific component of the product to be dispensed into the container.
  • the tank is provided with an identification code which uniquely identifies it and said code being read using appropriate readers. Following the reading, it is possible to optionally but preferably provide a step for disabling the identification code of the tank. This makes it possible to avoid abusive use of the tank, for instance to fill it by service personnel with a component that does not come from, and therefore is not guaranteed by, the company supplying the system.
  • the identification code of the tank can be in the form of a physical identification code such as an optical type identification code, for instance a barcode or a QR code or in the form of a code stored in an electronic tag, for instance in an RFID tag or similar.
  • a physical identification code such as an optical type identification code, for instance a barcode or a QR code
  • an electronic tag for instance in an RFID tag or similar.
  • the identification codes of the tanks are managed by a computer system and are stored in a database as they are associated with a status variable which can take on two conditions, namely an enabled code and a disabled code.
  • the reader of the electronic tag can also transmit to said electronic tag commands which make the electronic tag at least temporarily non-functional or which make it stably and irreversibly unusable.
  • the electronic tag reader transmits to the electronic tag commands for activating/deactivating and/or disabling code transmission or canceling the code.
  • the two types of codes can also be provided together on a tank, each being managed independently of the other.
  • the reader and/or a unit configured to perform the following function, send commands or subject the electronic tag to signals capable of making the tag stably and irreversibly unusable.
  • step 108 makes it possible to make the corresponding tank unusable once it has been removed from the system. A new installation will result in the non-recognition of the tank due to the disabling of the code and the generation of an error message as well as the interdiction of the execution of the withdrawal and dispensing steps.
  • the next step indicated with 107 foresees that on the basis of the identification code of the tank the information of the type of component contained in the same is retrieved.
  • a first embodiment provides that the information is contained in a local control system associated with the dispensing system.
  • An embodiment which can also be provided in combination since it can be activated alternatively or in partial combination with the previous one, provides that all the information and/or at least a part of it is retrieved and downloaded from one or more databases provided and managed in a remote server, for instance at the supplier or manufacturer.
  • Step 109 is a step that can be optional, for instance in the case that the system and the method are aimed at a product which consists only of mixing a single component contained in a single tank which is mixed when dispensing to the container with a pre-established component in a pre-established dilution ratio.
  • the method provides that for each component of the product, for the component of at least one tank and for instance for the diluent or solvent, separate and independent ducts are provided for withdrawing the component from the tank and the diluent or solvent, which are configured to dispense each independently one of the other the corresponding component and diluent.
  • the independent dispensing step can advantageously be combined with a step of measuring the amount of each component, including the diluent or solvent, which is dispensed to the container.
  • the diluent can have a duct permanently dedicated to it, so that a further separate duct is always free for dispensing and dosing said single component from the tank. Therefore, loading it into the tank in the system and connecting it to the dedicated dispensing/metering duct does not require recognition of the duct and an operation of logical and unambiguous association of the same to the tank.
  • the product to be dispensed into the container can be composed of a diluent or a solvent and at least two different components, each contained in a different tank, each of said tanks having its own identification code which associates it uniquely to the component it contains.
  • the method which provides for the separate dispensing of each component provides for a separate dispensing/metering duct for each tank, so it is advantageous to provide a step for identifying the dispensing/metering duct which is connected to the tank and a logical association of said duct to said tank in order to uniquely correlate the tank, the dispensing/metering duct, the component contained in the tank and the quantity of said component to be dispensed to the container according to a predefined recipe of the product intended to be contained in the container.
  • the identification codes of said one or more installed tanks and/or of the relative components contained therein and/or of the delivery ducts associated with each tank are checked for compatibility with the identification codes of one or more containers intended to contain the product and/or the corresponding product, or the recipe that defines the combination of components and their quantity for said pre-established product and/or also possibly with the user identification codes as will be seen in greater detail in the following description.
  • the left branch of the flowchart relates to the method steps related to the recognition of the container and therefore of the product intended for it and/or also to the recognition of the user and the enabling of the same to be able to receive said product.
  • a container filling request is performed. Following this request, a user recognition step is performed as indicated with 101.
  • This step can be performed in several ways, including:
  • the method provides for verifying which products the user is authorized to use for as indicated in step 102.
  • step 103 the unique identifier of the container is read, which in the present method is uniquely linked to a specific product.
  • the unique and stable correlation between the identification code of the container and the product is generated through a database or a correlation table stored in a control unit of the system which can be a local unit or a remote server unit.
  • the container in addition to its identification code, carries a further identification code of the type of product which is intended to be contained therein.
  • the method provides for identifying the recipe relating to the combination of components and their quantity for making the product uniquely associated with the product code and/or with the identification code of the container according to one of the two variants described above.
  • the aforementioned information is then sent to section 110 where compatibility is verified between the user requesting a specific product intended to be contained in a specific container, the recipe of the combination of components which make up the product, the presence of the tanks which contain said components. These compatibility checks take place on the basis of the unique identification codes of the container, of the user, of the product and of the tanks and therefore of the components contained therein.
  • step 111 In the event of no positive check of compatibility between the above information, the process is stopped and an error signal is emitted as indicated in step 111.
