Device and method for mixing a fluid product contained in a closed container
View Patent ↗A mixing machine for mixing a fluid product contained in a container, comprising one or more mixing devices, each able to mix the product according to a determinate mixing cycle chosen from a plurality of elementary mixing cycles. A command and control unit has a first memory in which the operating sequences of the plurality of elementary mixing cycles are memorized, and is connected to a data introduction device associated with a second memory in which the characteristics of the container or of the product to be mixed are memorized. Each operating sequence of the determinate mixing cycle is pre-defined according to the characteristics memorized in the second memory.
1. A mixing machine for mixing a fluid painting product consisting of a base component and an added dye, contained in a removable, selected and closed container, comprising:
one or more mixing devices each configured to receive said removable, selected and closed container and to mix said fluid painting product according to a determinate mixing cycle, said determinate mixing cycle being a combination of two or more elementary mixing cycles chosen from a plurality of elementary mixing cycles, wherein each of said one or more mixing devices comprises:
a clamping mechanism configured to selectively clamp said removable, selected and closed container with a determinate clamping force by means of a command electric motor; and
a main electric motor able to impart to said removable, selected and closed container the movements necessary to mix said base component with said added dye, so as to obtain a homogeneous fluid painting product;
manually operable data introduction means for manually introducing the characteristics of said removable, selected and closed container and of said fluid painting product, and;
a command and control unit having a processing unit connected to said manually operable data introduction means and able to control and selectively drive both said command electric motor and said main electric motor of said one or more mixing devices according to the data manually introduced by means of said data introduction means, wherein said command and control unit comprises a first memory connected to said processing unit and in which both the operating sequences of said plurality of elementary mixing cycles and also the definable characteristics of the different fluid painting products to be mixed, of the different types of removable, selected and closed containers and the different mixing devices to be controlled are memorized,
wherein said manually operable data introduction means are connected to a second memory connected to said processing unit and in which the characteristics of said removable, selected and closed container and of said fluid painting product to be mixed are able to be memorized, and
wherein each operating sequence of said determinate mixing cycle is automatically pre-defined and controlled by said processing unit according to said characteristics of said removable, selected and closed container and of said fluid painting product to be mixed memorized in said second memory by means of said manually operable data introduction means.
2. A mixing machine as in claim 1 , wherein each at least one of said mixing devices also comprises repositioning means able to position said removable, selected and closed container in a determinate initial position at the end of said determinate mixing cycle, wherein said repositioning means comprises an electric actuator and an associated repositioning sensor connected to said processing unit.
3. A mixing machine as in claim 1 , wherein said mixing device comprises detection means able to detect the position or the velocity of said main electric motor and of said command electric motor and to generate corresponding electric signals for said processing unit.
