Description

Device for automatic painting of small parts.

Object of the invention

The present invention relates to a device that has been designed to allow carrying out automatic, simple and efficient way, painting small batches or series of parts such as screws, stones, metal parts, sands of quartz, rubber, or any other object of reduced dimensions and whose number make your painted unitary It is unfeasible.

The object of the invention is to provide a device that allows to ensure a correct painting of the pieces in question, that is to say all of its
surface.

Background of the invention

As is known, when carrying out the painted small pieces, such as those above commented, its unitary painting is unfeasible, of so that these are usually arranged on a surface or background splash guard, so that with a paint gun or similar equipment, approximately half is painted of the surface of the pieces, after which it is necessary to turn the same to proceed to the painting of the other half of his surface.

This flipping task is slow and laborious, especially when it comes to very small pieces, at that we must add the problem of painting elements with rounded, cylindrical or spherical surfaces, with little stability, so that the paint pressure itself causes these turn on themselves, not being able to ensure a correct painted them.

Description of the invention

The device for automatic painting of small pieces that the invention proposes solves in a way the problem described above is fully satisfactory, carrying out the entire painting process completely automatic, and ensuring a correct painting of the entire surface of the pieces to paint.

To do this, and more specifically, the device that is recommended is constituted from a hype formally and dimensionally suitable to receive within them pieces to paint, equipped with a folding front cover with a hole facing a paint gun associated with compressed air equipment and assisted by a tank of painting.

The aforementioned bass drum will be associated with an electronically controlled moto-reducer unit, through a control circuit, through which the multiple options offered by the
device.

So, after opening the bass drum lid, e insert the parts to be painted inside, and close the lid, will proceed to position in front of the hole of the same the gun of painting, and then, through the control panel of the device to start the painting process.

In this way, the mentioned gun will project spray paint on the inside of the bass drum, which, thanks to the moto-reducer team associated with it will make this turn in one direction and another, facilitating the rotation of the pieces introduced into the heart of the hype and consequently the perfect painted all of its surfaces.

Once the painting process has been carried out, has foreseen that the paint gun itself can be used in the drying process of the painted parts, for which, and by actuating the corresponding solenoid valves, paint access will be cut to it, so that, by a heating system associated to the bass drum by resistance electric, automatically heats to the proper temperature of work inside the bass drum to reduce drying time of the pieces, after which, equally automatically, the hype  Tilt down, to pour products by gravity contained within it on the corresponding container.

The dashboard or control panel of the control circuit will allow to visualize and control all process parameters, such as start-up, stop, pause, emptying, gun position, regulation of the spraying, emergency stop as well as control of the drying air temperature.

Similarly, the device will incorporate hype and gun positioning sensors that prevent machine malfunction, also generating corresponding light alerts that warn users of such incorrect positions.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a single plan where illustrative and non-limiting nature, has been represented in perspective a device for automatic small painting pieces, made in accordance with the purpose of this invention.

Preferred Embodiment of the Invention

In view of the review figure, you can observe how the device of the invention is constituted to starting from a frame (1), of a metallic nature, on which establishes a bench (2) on which a tank (3) is tilting to through the corresponding axis of rotation (4), controlled electromechanically through a control circuit housed in a cabinet (5), provided on its front face with the corresponding panel of controls (6).

The aforementioned Cuba (3), similar to the structure of a concrete mixer, in addition to being able to swing with with respect to the horizontal axis (4), it can rotate both in one and in another sense with respect to its generatrix, through corresponding moto-reducer group, likewise associated with the control circuit housed in the cabinet (5).

Said tank (3) has a suitable size for receive the pieces to be painted inside, presenting a tubular configuration of circular section, open on its face above, in correspondence with which a cover is established (12) jointly attached to the tank through a hinge or hinge (7), said cover having a circular window (8) arranged centered, so that in the painting process, facing said circular window (8) a paint gun (9), foldable through one arm (10) to allow better access in filling and emptying maneuvers of the Cuba, dejection that may be assisted by the corresponding electromechanical mechanism, such as a group moto-reducer or similar, which will be assisted by the corresponding control circuit.

The mentioned gun will be connected to a team pressure, housed inside the cabinet (5), as well as a paint tank (11), its drive being equally controlled by the control panel (6).

The programming differentiates the times of painted and dried differently according to the change of rotation in the Hype for both work times.

For this, the control panel will have a thermostat (13), with a programming interface (14), a push button emergency stop and reset (15), a pressure gauge (16) and a command pressure regulator (17), the corresponding button on / off (18), a start button (19), a pause button (20), a gun positioning control (21) and a tank emptying control (22) on the corresponding container (23).

Thus, through the interface (14) of programming may regulate the times of painting, drying, temperature, etc., involved in the process.

Finally, and as already mentioned with previously, the device will incorporate a series of sensors positioning of the tank and the gun, generators where appropriate the corresponding visual alerts through the interface (14), so that if the gun is improperly placed, avoid any maneuver other than emptying, while if the bass drum is not is in the painted position, the gun is disabled, both in Its painting as drying functions.

At the end of each cycle it will be necessary to execute a cleaning program, put the electric controls in position of off, and check that the air pressure is zero.

In this way a device is achieved that it allows the painting of the pieces contained in its tank in a way Easy, fast and simple, completely automatically.
