(54) SYSTEM FOR DOSING AND APPLYING COLOURS


(57) (EN) The invention relates to a system for dosing and applying colours, comprising a head (1), a computer (2), a liquid-dosing device (3), a liquid container (4) and an air-generating compressor (5). The inventive system can produce a colour signal based on micronized pigments and the dosing is controlled with a computer (2). The novel system is essentially characterised in that the colour and the thickness of the lines can be changed dynamically and whole images can be reproduced on the painting surface, preferably a ceramic surface.




Description

Purpose of the invention.



[0001] In this descriptive report presents a dosing system and application colors, mainly on ceramic surfaces capable of achieving a color signal with powdered pigments, the dosiflcadón being controlled by a computer. The main feature of this new system is the ability to dynamically change Color and the thickness of the lines, as well as the ability of reproducing images Complex on the surface of painting, preferentemen a ceramic surface, or other as glass, paper, canvas, etc..

Antecedents of the Invention.



[0002] So far in the state of the art have been presented different systems Decoration on all kinds of surfaces with poor results. These systems, in some cases are based on systems inyecci6n ink, drums or other serigraficos Conventional printing.
In the Spanish patent ES8703298 it's describes a machine Applying dosing Colors, which is identical to the object of the present invention patent but not However, presents the following problems that preclude its use practical:

This document indicates that the powdered pigment aspired for a Strawberry-shaped shield Cylindrical until center.This it's not true.

Since the strawberry obstruct.It's need additional air, which causes the powder obtained by scraping, and a change of shape cylindrical to spherical or conical.

The airbrush with needle positioning, described in this patent haven't reapited, requiring its replacement by a new Pump-spray liquid,with greater accuracy and repeatability. the chambers where they are housed mines are not Waterproof. Without this Sealing,

The pulverized wouldn't only goes out by the center, which Be used elastic sealing elements at the entrance to the mines (pigments aglutinates, with cylindrical shape), as the bearings with roadblocks.

In the patent analyzed Airbrush touches moving parts that produce the turn of the strawberry. The present invention patent spray does not touch the moving parts that produce the turn of the drill at the same time serves as the lid at the top of the head, so that the air comes out solely by the tip.The mines are progressing and revolve. The present invention patent only progressing.

There is no autoloader of mines.


Description of the invention



[0003] To overcome the problems stated above, presents the dosing system and implementation of colors, the subject of the present invention. Distributed around a strawberry spherical or conic,mines are powdered pigment agglutinated. The strawberry spray mines, which together with the air coming from the air intake creates a flow of air and dust in the direction of the needle on the tip of the spray, which is mixed with the liquid spray, leaving the pigment, and the liquid air mixture to the surface to decorate.
The system supports as many color mines as desired. These mines agglutinated pigment powder, as we move towards the rotary cutter sprayed and dust resulting beacome outward. The mines are driven by electric motors, with the speed of motors controlled by computer, so that it is controlled by dosage of pigment. Through the relative speed of the motors that make advance mines controlled color, as an increase or decrease speed. It also controls the flow of water, depending on the speed of the plunger pump fluid and its distance from the surface to decorate regulates the size of the line. Also available A loader automatic deposit of pigment, which allows when one of the mines of pigment is finished, it passes followed the next.

[0004] If we move, the structure of the head, which is the group formed by the spray and strawberry spherical or conical either the surface to decorate, in the three dimensions of space with a structure suitable mechanical beeing also their movements controls engines eletricos governed by from a computer,the system may have to run a trayectorie along, with a desired color, and therefore represent any. image you want Through this system is achieved represent any image you want on any surface, preferably ceramic, gathering the charactereristica of the dynamic change of color and line desired.

Description of the drawings



[0005] To complement the narrative that is being done in order to help a better understanding of the characteristics of the invention, is accompanying this description,as an integral part of it, a number of figures in which , as an illustrative and not restrictive, it has been represented as follows:

Preferred Realization of the invention



[0006] As one can see in the accompanying figures, the dosing system and application of color is basically composed of a head (1), a computer (2), a device liquid dispenser (3), a reservoir of liquid (4) and (5) a compressor, air generator.(2) The computer controls the system through a plaque controller of 8 axes simultaneously, over 8 drivers, plus a power supply. Thus, software controls the movement of 8 variables of the system as well as any accessories (relays, etc..),Or 4 color bars, a sprayer and three axes of situation, being able to move to election the surface to decorate, the head or both. The liquid enters the dispenser (3) from a tank (4) through the solenoid valve (51), which enables automatic recharging of liquid in the bottle.The liquid dispenser (3) is responsible for referring the liquid from the tank (4) to the sprayer (11) located at the head (1). The operation of this pump (3) consists of a plunger (50) controlled by an electric motor which in turn is Ruled by the computer (2), so that program can be controlled by the amount of liquid required in the sprayer (11) depending on the needs of each design you want to implement the system.
The head (1) is composed mainly of mines of pigment (20), the automatic feeder mine (21), the sprayer (11) and strawberry (12). The head (1), sealed by a lid (13), which is part of the sprayer (11), has an entry of liquid (110) from the dispenser (3) and an air inlet (111) from the compressor (5). The head (1) also has a strawberry (12) circular or conical, with its movement controlled by an electric motor via a transmitter (14), which, in its turn, and scratch the mines, (20) located on the sides of the head (1), the switch strawberry (12) sprayed what mine are progressing (thus leaving the camera scraping always in the the same way). The air from the entry (121) creates a flow of air and dust in the direction of the tip of the sprayer (11) where it is mixed with the liquid spray, and from the tip of the spray bottle (11) is where the pigment mixes, the liquid and air to the surface to decorate or paint
. The operation of the spray is based on the liquid leaving the pump (3) passes through a small diametertube with a needle in it. Around this pipe there is a very fine crown where that leaves the air, resulting in the spraying of liquid dosed by the plunger (50), avoiding the trickle that will occur in the case of free fall of the liquid without the push of air.
All described movements are controlled by the computer (2) through electric motors.Thus, there is an electric motor (servo motor, step by step, etc.). For the movement of each of the XYZ axes well of the head, either from the surface to decorate, one for dosing the liquid(3), other for the movement of the strawberry (12),and others (servo-motors, step by step, etc.).for the mines.

[0007] Are. Once, sufficiently described the nature of the present invention, as well as a way to implement it, only remains to add that the invention may suffer some variation in form and materials, as long as these do not vary Substantially the features that are claimed below.
