A device for instant manufacture of customized paint, a control system for use in the said device and a process for making the paint using the device

摘要

A device for instant manufacture of customized paint is disclosed. The device comprises a first container (1) housing at least two cans (2) for holding ingredients useful for preparing the paint. Each can is provided with an opening through which the cans are interconnected by means of a first pipe (3). This first pipe is provided with valves (4) which operate on electronic signals for adjusting the flow of the said ingredients from the said cans. A second pipe (5) is connected to a pump (6) for pumping the ingredients from the said cans into a second paint container (7). The pump is provided with a variable frequency drive (8) for varying the flow rate of the quantities of the ingredients from the said cans to the paint container. The paint container is removably placed on a weighing platform for weighing the paint formed in the paint container. The weight is transmitted to a control system to control the variable frequency drive, the pump and the valves. The control system (10) comprises an embedded controller having a liquid crystal display (11) provided with a central processing unit (14). The output of the weighing platform (9) is connected to the central processing unit. A first terminal of the central processing unit is connected to the liquid crystal display. A second terminal of the central processing unit is connected to a smart card (15). A third terminal of the central processing unit interacts with a memory (17). A fourth terminal of the central processing unit is connected to the input of a digital input/output device (16). A fifth terminal of the central processing unit is connected to a membrane keyboard (12) for human interface. The output of the digital input/output device is connected to a relay board (18), and the output of the relay board is connected to the variable frequency drive and to the valves.
