[0093] As a preferred embodiment of the invention, the container-shaped housing (54) of the machine for mixing and dispensing liquid detergent has a height: 2.40 m [7-10, 49 (ft-in)], width: 1.40 m [4-7, 12 (ft-in)], depth: 0.90 m [2-11, 43 (ft-in)], Area (s/door): 2.83 m.sup.2, tank capacity: 520 L, estimated weight of the equipment without product: 180 kg (396.83 lb), alternating current input: 110-120 V, frequency between 50-60 Hz, maximum consumption: 2 A., electronic system with a 12 Vdc source 10 A and TTL control system and relay system and light and motor control driver. The machine to mix and dispense liquid detergent has a communication system to establish connection with external peripherals, using any existing protocol; linear bar code reader scanner, the touch screen (40) of the equipment provides information in real time (HMI).

[0094] Inside the inspection hatch of hydraulic system (53) in the lower part, the machine has a pump designed for the efficient dispensing of the product, tank and auxiliaries designed and manufactured to guarantee the stability of the product, filling spout designed to adapt to any bottle neck diameter that enters the container holder, maintaining laminar flow with anti drip mechanism.

[0095] FIG. 19 shows a top view of the dispensing frame (56) with the screen (40) and the scale (55) shown in detail in FIG. 20 and that is responsible for calculating the weight of the material dispensed in the filling container.

[0096] Inside the dispensing frame (56) preformed of polyester reinforced with glass fiber is the packaging carrier (69) made of stainless steel, designed to control by weight the volume of product to be dispensed by means of a scale (55) screwed to a flange (70), welded to a support tray (71) and connected to a cylinder (72) spacer to the weighing tray, the design provides for the timely drainage of possible product spills.

[0097] The automation software executes the device components shown in FIG. 21. It must be taken into account that for the installation of the machine to mix and dispense liquid detergent the area for the installation of the equipment must have 2 m wide, 1.5 m of depth and 2.5 m of height; the equipment must be connected to a stable alternating current source (57) between 110-120 V, 50-60 Hz with a maximum consumption of 2 A and verify the grounding and must be placed, avoiding exposure to sunlight and maintaining a distance of 3 meters from other electronic equipment. The alternating current (57) passes through an AC-DC converter (58) from alternating current to direct current when the screen is manually executed (40).

[0098] As a way of executing the invention, according to that with FIG. 21, assembling in a mother card (59) the level sensor (60) of inventory, scanner (61), bottle presence sensor (62), cells charge (63), peristaltic pump (64) with its cell counts pulses (65). The connection where the products to be dispensed flow is carried out with hoses resistant to the products to be dispensed; where said products move from the dispensing tank to the safety key, then from the safety key to the peristaltic pump (64) which is controlled by the automation software and continues from the peristaltic pump (64) to the filling peak.

[0099] The motherboard (59) is a programmable autonomous electronic card that can be Arduino type programmed with programming language C, in a development environment provided by the same manufacturer of the card that has been selected in a standard for the development of applications of process control. The mother card (59) has a relay card (66) connected; This relay card has 8 relays with coil (67) of 12 VDC and with capacity to support loads up to 10 amps. The relay card (66) is used in conjunction with the motherboard (59) to activate and deactivate control elements, such as valves, motors or sensors. Each relay is an independent output that can be used at any time by the control program resident on the motherboard (59) to take action on the control elements of the process in operation.

[0100] Particularly, the fluid dispensing machine has a dispenser provided with a control panel which is contained in a protective vault with all the electronic parts and parts that govern all the processes of the machine and a housing containing: a power source (57) whose function is to feed the mother card (59) and its computer; Two Electro Fans (73) used to guarantee the temperature of the following parts: power source (57), motherboard (59) and its control and communication card (74), relay card (66) and connection terminal; where the Relay Card (66) is used to control the output signals sent by the control card to the following components: Peristaltic pump (64), Container sensor (62) that validates the presence of container on the scale (55); Load Cells (63) which is the control instrument for the dispensing volume dispensed; Level sensor (60) used to control the level of the Main Tank; touch screen (40) with computer that informs the user the steps to follow to execute the purchase of the product and Bar Code Reader (41) used to activate the filling process of the container.

[0101] The power source (57) is 12 Volts DC and 10 amps capacity. The power source (57) is used to electrically energize the control cards.

[0102] As the machine's execution inputs, there is the Bar Code reader (41) that is fixed and captures virtually a wide range of codes. It also has as an input peripheral the screen (40) that allows the interaction with the mother card (59) of the equipment, connected by the I2C communications protocol and energized by the power source (57). The automation software runs on the motherboard (59) and uses the screen (40) to inform the user of the sequence of the purchase process and displays notifications of initiation and completion of the processes to the user.

[0103] FIG. 22: It shows a diagram of interconnection and operation of the device with the operation of a management software on an internet connection platform and a server by the owner and technical support personnel for executing a set of touch screens (40) simultaneously under connection via internet with a technical terminal (76), a franchised operative terminal (77), a second franchised operative terminal (78) and the interaction with a central server (79).

[0104] According to the dispensing software of FIG. 2 and the operating process that is executed from the touch screen (40) the following steps must be followed: [0105] Connect the equipment to the AC power supply (57) [0106] Turn the ignition switch to the ON position. [0107] The permanent illumination led indicator will light up. [0108] Touch the touch screen (40). [0109] The touch screen (40) will request an access code. [0110] The Data Record screen appears in white. [0111] The touch screen (40) has two options to move between screens, they are two arrows located at the bottom. [0112] When you touch the arrow with the word Next, you will be presented with the calibration screen, the procedure is at the bottom left of the screen. [0113] The touch screen (40) has two options for moving between screens, two arrows located at the bottom. [0114] When you touch the arrow with the word Next, you will be presented with the Current Tank Content (L) screen, the procedure is at the bottom of the screen. [0115] By touching the arrow with the word Next, you will be presented with the Diagnostic Screen, in which the technical service personnel can verify the correct operation of the equipment. [0116] Touching the CLIC logo located in the upper left part of the screen returns to the main screen, and finishes the process of set-up of the equipment. [0117] Next, the dispensing software is activated and the user must place the container in the container and insert the filling spout into the neck of the container, in the touch screen (40) the following message will appear: Place the Bottle . . . !!, the led indicator of container presence will light up and the scanner laser of the bar code reader will activate. [0118] The touch screen (40) will show the message Present the Ticket . . . !!, proceed to present the barcode on the reader. [0119] Start dispensing the product to the container. The touch screen (40) will show the following message: Dispatching, please wait . . . !!
