Claims (25)

1. System (100) for supplying a certain amount of coffee beans to a beverage preparation device for preparing a coffee drink, moreover, the system contains a sealed container (20) of variable volume with a receiver (22) of a certain volume, in which coffee beans are stored, while the receiver (22) of a certain volume is made with the possibility of changing its internal volume to adjust it depending on the number of coffee beans stored in it. grains; moreover, the system (100) additionally contains an active dosing device (30) configured to move coffee beans relative to the receiver (22) of a certain volume, while the dosing device (30) is also airtight with respect to the external environment when coffee beans are moved. 2. The system (100) according to claim 1, in which the dosing device (30) is configured to function as a pump or reverse pump for moving coffee beans from the receiver (22) of a certain volume or to the receiver (22) of a certain volume, respectively. 3. System (100) according to any one of paragraphs. 1-2, in which the dosing device (30) in contact with the coffee beans is made of a compressible material whose hardness is lower than that of the coffee beans. 4. The system (100) according to any one of the preceding claims, in which the container (20) of variable volume contains a piston element (21) displaced by gravity inside the receiver (22) of a certain volume to adjust the internal volume of such a receiver depending on the number of stored it contains coffee beans. 5. System (100) according to claim 4, wherein the piston element (21) further comprises a pressure control valve (26) with a threshold pressure equivalent to the weight of the piston element (21). 6. System (100) according to any one of paragraphs. 4-5, in which the piston element (21) tightly closes the receiver (22) of a certain volume as a cover. 7. The system (100) according to claim 1, in which the receiver (22) of a certain volume is made in the form of an airtight elastic container capable of shrinking and reducing its volume to adjust it depending on the volume of coffee beans remaining in it. 8. System (100) according to any one of the preceding claims, wherein the dosing device (30) comprises two counter-rotating cylinders (31, 32) in direct contact with each other during the delivery of coffee beans. 9. System (100) according to any one of paragraphs. 1-7, in which the dosing device (30) comprises a pair of gears engaged in engagement for moving coffee beans from and into the predetermined volume receiver (22). 10. The system (100) according to any one of the preceding claims, further comprising a weighing device (40) located at the outlet of the dosing device (30) for weighing the supplied grains. 11. The system (100) according to claim 10, wherein the weighing device (40) controls the operation of the dosing device (30) and thus the amount of coffee beans to be dispensed. 12. The system (100) according to any one of the preceding claims, further comprising a control unit (50) controlling the operation of the dosing device (30) depending on the type of coffee beans and/or the coffee beverage being prepared. 13. System (100) according to any one of paragraphs. 10-11, additionally containing a control unit (50) that controls the operation of the dosing device (30) and the weighing device (40) depending on the type of coffee beans and/or the coffee drink being prepared. 14. System (100) according to any one of paragraphs. 12-13, in which the control unit (50) further comprises a mechanism for monitoring the torque generated by the dosing device (30). 15. The system (100) according to any one of the preceding claims, further comprising a mill (60) which receives the beans supplied by the system (100) and which converts them into roasted and ground coffee. 16. The method of actuating the system (100) for supplying a certain amount of coffee beans to the device for preparing a drink for preparing a coffee drink according to any one of paragraphs. 1-15, and the method includes the following steps: the system (100) is to supply a certain amount of coffee beans to prepare a certain coffee drink in the drink preparation device; depending on the coffee beverage to be prepared and/or the characteristics of the coffee beans to be supplied, the dosing device (30) operates for a certain time in order to supply the required amount; the container (20) of variable volume changes the internal volume of the receiver (22) of a certain volume in order to adjust it depending on the number of stored coffee beans, eliminating any replacement of free volume with air in the receiver (22) of a certain volume. 17. The method according to p. 16 for actuating the system (100) according to any one of paragraphs. 10-12, in which the control unit (50) in the system (100) controls the operation of the dosing device (30) and, optionally, the weighing device (40), depending on the type of coffee beans and/or the coffee beverage being prepared. 18. The method according to claim 17, in which the control unit (50) is connected to the mill (60) in the beverage preparation device or in the system (100), so that the control unit (50) transmits to the mill (60) the grinding parameters for the supplied coffee beans depending on the coffee drink being prepared and/or the characteristics of the coffee beans served. 19. The method according to any one of paragraphs. 17-18, in which the control unit (50) receives information from the interface or HMI about the prepared coffee drink, and then communicates with the database to obtain information about the number of coffee beans needed and grinding parameters to send a command to the dosing device (30) and the mill (60) respectively. 20. The method according to any one of paragraphs. 17-18, in which the user enters into the control unit (50) information about the number of coffee beans and/or grinding parameters to command the dosing device (30) and the grinder (60), respectively.
