    Automatic system for blasting parts. The system of the invention, based on a conventional robotic blasting arm, centers its characteristics in that it, instead of presenting a fixed and immovable position, is arranged on a telescopic axis (3), vertically movable, which in turn is horizontally movable, along the Y axis through a second carriage (13), which in turn is controlled scrollable on longitudinal guides in the X direction, through a first carriage (8-8'). In this way, it is possible to position the robotic arm in virtually any position with respect to the piece to be shot, thus avoiding having to constantly change its position to carry out said shot blasting process.

    [0004] OBJECT OF THE INVENTION
    [0005]
    [0006] The present invention relates to an automatic system for blasting parts, robotic system, specifically intended for the blasting of steel parts intended for both the wind and rail sector, auto-motor industry and others, including a telematic maintenance system that allows generating a control and preventive maintenance service.
    [0007]
    [0008] The object of the invention is to provide the steel blasting sector with a system capable of adopting multiple positions in order to significantly improve the blasting performance, and utilizing angular and metallic shot to achieve a better finish of the pieces.
    [0009]
    [0010] BACKGROUND OF THE INVENTION
    [0011]
    [0012] Normally in the shot blasting, spherical shot is used, being carried out in cabins with an inner EDPM rubber coating, for the protection of the impact of the shot, with the particularity that the cabins can be both manual and automatic, but in any case the Shot blasting is carried out by means of turbines, and in the best case with the collaboration of a robot that although it presents certain degrees of freedom, it is fixed with respect to a point of the cabin, so that its mobility is quite limited and consequently it is necessary to constantly change the position of the pieces to be shot, with the loss of time that this entails.
    [0013]
    [0014] DESCRIPTION OF THE INVENTION
    [0015]
    [0016] The system that is recommended solves the problem described above in a satisfactory way, using angular shot, much more abrasive than shot Conventional spherical, although it allows to use any type of shot, and even sand, allowing the shot of said shot from multiple positions, without having to constantly vary the position of the pieces to be shot.
    [0017]
    [0018] More specifically, the system of the invention includes a robot, capable of being located inside the cabin, allowing a large number of movements, both linear and angular displacement, to be carried out in order to allow the blasting of parts without having to change these position in said shot blasting process.
    [0019]
    [0020] The cabin (internally) and the set of the machine elements is covered with polyurea, which prevents the mobile elements of the system from being hitched, as is the case with rubber coatings.
    [0021]
    [0022] Structurally the system comprises a series of commercial structural steel pillars, welded and custom machined, on whose pillars the X-axis beams are supported, these beams being designed from calibrated and machined steel plates and assembled by screws to avoid welding , thereby improving the final precision in the assembly. On said beams, the X-axis carriages are moved, which are transversely joined by the Y-axis beams, designed, manufactured and mounted using the same bolted system as the X-axis beams mentioned above. On the beams of the Y axis, the carriages of the Y axis are moved, which are joined by two beams that will support the Z axis.
    [0023]
    [0024] This second carriage has a telescopic axis along the Z axis, also obtained from calibrated, machined and screwed steel sheets, so that said axis, being telescopic, has the capacity to be collected and lengthened depending on the required application, incorporating cestilene or nylatron skates in which several needle bushings are assembled, depending on the load to be supported, skates that are located between the steel tubes that form the Z axis itself, to facilitate sliding between them.
    [0025]
    [0026] The lower extremity of said vertical telescopic axis will be finished off in the classic shot blasting robot, that is to say in an articulated arm with several degrees of freedom, and topped off in the corresponding shot nozzle.
    [0027] As for the movements of the different cars and Z axis, say that the mechanism of movement in the X and Y axes, is constituted from lower and upper guides through which the wheels of respective cars circulate, so that to be able to move The whole system uses a rack and pinion system to which the torque is transmitted through a servomotor, a gearbox and an angular forwarding.
    [0028]
    [0029] As for the vertical telescopic axis or Z axis, the drive is carried out through a hoist to which the original motor is removed and a servo motor driven by the robot controller is coupled. In this way, the path of the different sections of the axis is controlled by an external axis of the robot console, as the smallest section of said telescopic structure is associated with the chain of the hoist.
    [0030]
    [0031] For its part, the programming of the robot can be done by means of a screen, as is done conventionally, or by means of a CAD / CAM program, a tool used in the process automation programming with robotics.
    [0032]
    [0033] The telematic system that incorporates the invention is intended to collect data as well as allow real-time access to the process, allowing a thorough evaluation of the operation as well as the establishment of an appropriate maintenance system, using the information on the operation of each servo. engine and communicating with the control panel to transfer this information in hours of use of wheels, bearings, guides, zippers, needle bushings, skates, etc., so that with this information you can define the hours of use of each component and generate alarms on the general screen when maintenance or replacement of each component is necessary.
    [0034]
    [0035] Finally, to say that the system of the invention includes means for verifying the pieces by means of a sensor chamber that measures and compares the roughness of the treated surface, so that the process is terminated by giving the piece OK or re-treating it. If so required.

    [0057] PREFERRED EMBODIMENT OF THE INVENTION
    [0058]
    [0059] In view of the figures outlined, it can be seen how the automatic system for the blasting of parts is constituted from a structure in which a series of steel struts or pillars (1) participate, which constitute a support for longitudinal bars (2), equipped with guides (6) through which a first carriage (8-8 ') can be moved.
    [0060]
    [0061] Said carriage (8-8 ') is a carrier of beams with transverse guides (2') through which a second carriage (13) is movable, which is a carrier of a telescopic shaft (3), obtained from plates of steel, in which different tubular sections of progressive smaller section are defined, related to each other through skates (4), with needle bushings (5) as rolling means.
    [0062]
    [0063] From this structure, the transmission of movement in the X-axis is determined by the displacement of the first carriage (8-8 ') and the second carriage (13), respectively, based on a system of guides (6 and 6' ) upper and lower than the longitudinal bars (2), through which the wheels (7) associated with the plates in which the first carriage (8-8 ') is finished, using for this displacement a rack-and-pinion pinion system (9) associated to the longitudinal bars (2), operated by a servo motor (10), a reducer (11), with angular forwarding.
    [0064]
    [0065] The displacement in the Y axis, that is to say of the second carriage (13) with respect to the guides (2 ') that are established between both ends of the first carriage (8-8'), will be analogous to that described above, that is, incorporating also said guides (2 ') zippers for the movement of the car through a pinion associated with a motor-reducer group.
    [0066]
    [0067] Finally, the displacement in the Z axis in which the telescopic axis (3) materializes, and which is topped off in the classic robotic arm (14) with several degrees of freedom, and in which the nozzle of discharge of the shot, is achieved by a hoist that will be inserted into the second carriage (13), associated with a servo motor governed by the system control electronics, hoist whose chain is internally linked to the lower or smaller end of the telescopic sections that participate in the telescopic axis (3), so that through this element the extension and telescopic retraction of said axis is controlled.
    [0068] It only remains to point out finally that, as previously stated, the system is programmable by means of a screen or by means of a CAD / CAM program, including telematic means that collect data for the evaluation of the different parts that participate in the device. in order to maintain proper maintenance thereof, including also means of verifying the parts (12) by means of a sensor chamber that measures and compares the roughness of the treated surface.
