    [0003]
    [0004] Technical sector
    [0005]
    [0006] The present invention is related to the cutting of sheets of any material by projection of a fluid, for example, by laser emission, without this fluid being limiting, proposing a machine for this function, with which characteristics that optimize the efficiency and versatility of the cuts for which the application is intended.
    [0007]
    [0008] State of the art
    [0009]
    [0010] It is known the practice of making cuts in metal sheets and other materials, to obtain conformations or parts intended for different applications, the method of laser projection or other fluids being known to precisely make the cuts in sheets for such purposes. .
    [0011]
    [0012] In that sense, there are laser cutting machines by laser projection or other fluids, comprising a projection head of the cutting fluid, located above a support table of the sheets to be cut, with means of moving the sheets by a cutting area located below the projection head of the cutting fluid.
    [0013]
    [0014] Thus, for example, documents US 20080168876 A1, DE 102004034256 B4 and GB 1287585 A, among others, describe sheet cutting machines by fluid projection, with a composition such as that mentioned, providing a support table and transport of the sheets to be cut, formed by two successive table sets, between which a gap is defined that is located below the projection head of the cutting fluid, so that, in the realization of the cuts, the cutting fluid once it crosses the sheet that is cut through that defined gap between the two successive table sets, without affecting any other element after the sheet crossed.
    [0015]
    [0016] Some of these machines even allow the gap defined between the two successive table sets to be varied, for making cuts of different dimensions, using table sets whose length can be modified to vary the distance between the facing edges of both successive table sets.
    [0017]
    [0018] However, currently known machines of this type represent expensive solutions that offer many problems, especially when moving the metal sheet on which the cuts are to be made.
    [0019]
    [0020] Object of the invention
    [0021]
    [0022] According to the invention, a machine is proposed to make cuts in sheets by projection of a fluid, for example, a laser emission, although it can be any other fluid, with some performance characteristics of said machine that make it functionally advantageous for the function of cut in the mentioned application with efficiency and versatility.
    [0023]
    [0024] This cutting machine object of the invention comprises a projection head of a cutting fluid, said head being provided with a three-dimensional controlled Cartesian movement and arranged above a support table of sheets to be cut, in which there is a space free that defines a gap for the passage of the cutting fluid after crossing the application sheet on which cuts are made with the machine.
    [0025]
    [0026] The support table of the sheets to be cut comprises a set of rollers arranged in free-spin assembly between carrier belts provided with a driving motor drive, the roller assembly being distributed in two groups spaced apart from each other by a space that determines the gap of passage of the fluid of cut, with entrance to the table of support, of the plates to cut, between some driving rollers that act the movement of the sheets to cut to move them along the table of support, while in connection with one end of the component rollers of the support table is arranged a synchronization belt which is provided with a drive motor drive combined with the drive motor of the input rollers to the support table of the sheets to be cut.
    [0027]
    [0028] In this way, a cutting machine is obtained in which, when the sheets to be cut are moved on the support table thanks to the drive of the input drive rollers, the set of component rollers of the support table is moved, to the time, rolling with respect to the sheet to be cut, thanks to the activation of the synchronization belt, whereby the passage of the cutting fluid moves along with the movement of the sheet to be cut.
    [0029]
    [0030] On the other hand, by driving the conveyor belts of the rollers that form the support table, a rolling movement of the support table with respect to the sheet to be cut is obtained and, therefore, a displacement of the passage gap of the cutting fluid with respect to the sheet to be cut.
    [0031]
    [0032] By means of a controlled combination, for example, by means of a numerical control, of the movements that affect the cutting head of the cutting fluid, the sheet to be cut and the support table of the sheet to be cut, it is therefore possible to obtain a functional activity of the machine to make very versatile and precise cuts.
    [0033]
    [0034] The two groups of rollers that form the support table of the sheets to be cut can, where appropriate, be incorporated between respective pairs of carrier belts equipped with independent drive motor drives, which can also be varied during the process of functional activity of the cuts with the machine, the dimension of the passage of the cutting fluid, thus making it possible to make cuts with the machine even more versatile.
    [0035]
    [0036] Below the cutting area, the provision of a structured grid-shaped transverse conveyor belt is also provided, through which the remaining fumes and small particles that occur in the cuts can pass, while the larger pieces or pieces resulting from the cuts are deposited on said conveyor belt that moves them outwards.
    [0037]
    [0038] Therefore, the recommended machine results from very advantageous features for the sheet cutting function to which it is intended, acquiring its own life and preferential character with respect to known machines of the same application.
    [0039]

    [0051] Detailed description of the invention
    [0052]
    [0053] The object of the invention relates to a machine for making cuts (3) in sheets (2) of any material, by projection of a laser emission or other fluid capable of passing through the sheets (2) to be cut, comprising a head (1) projector of the cutting fluid, arranged above a support table of the sheets (2) to be cut, the support table comprising a gap (6) through which the cutting fluid passes after crossing the sheet (2) on which cuts are made (3).
    [0054]
    [0055] The cutting fluid projector head (1) has a controlled displacement motor drive in three Cartesian dimensions, while the support table of the sheets (2) to be cut is formed by a set of rollers (4) that are incorporated in free-spin assembly between carrier belts (5), which, in turn, have a drive motor drive, the whole of the support table comprising two groups of rollers (4a) and (4b) that are separated between yes, determining the opening (6) of the cutting fluid, which is located below the position in which the cutting head (1) of the cutting fluid is located.
    [0056]
    [0057] At the entrance to the support table formed by the rollers (4) there are some feed rollers (8) provided with rotary drive, between which a passage of the sheets (2) to be cut is determined, which are displaced by said rollers of feeding (8) in longitudinal advance movement on the support table; while, in relation to one end of the rollers (4) that form the support table, a synchronization belt (7) is arranged, which comes into contact with the end of the rollers (4), preferably by gearing or friction, said timing belt (7) being provided with a drive motor drive combined with the rotary drive drive of the feed rollers (8).
    [0058]
    [0059] This results in a machine assembly with which, establishing a combined control, for example, by numerical control, of the Cartesian movement of the head (1), of the movement of movement of the carrier belts (5), of the movement of movement of the tape of synchronization (7) and of the rotating movement of the feed rollers (8), with the cutting fluid projected by the head (1), cuts (3) can be made on a sheet (2) that moves on the table of support, so that the cutting fluid after crossing the sheet (2) passes through the hole (6) without affecting any other element; cuts (3) of any configuration can be made under these conditions, since by means of the combination of the motor drive of the movements of the head (1), the motor drive of the movement of the carrier belts (5) and the motor drive of the rotation of the feed rollers (8) that move to the sheet (2), the recess (6) accompanies the movements of the head (1) so that the cutting fluid passes at all times through said recess (6), after crossing the sheet (2), in the realization of the cuts (3).
    [0060]
    [0061] In that functionality, when the sheet (2) to be cut is moved on the support table by means of the drag made by the feed rollers (8), the rollers (4) of the support table roll below the sheet (2 ), whereas, when the movement of movement of the synchronization belt (7) coincides with the movement of rotation of the feed rollers (8), the support table moves simultaneously and at the same speed as the sheet (2) ), so that there is no movement of the rollers (4) of the support table with respect to the sheet (2) and when the movement of movement of the synchronization belt (7) does not coincide with the movement of rotation of the rollers of feeding (8) that drag to the sheet (2), the rollers (4) of the support table roll below the sheet (2), without, therefore, at any time friction displacement of the rollers (4) of the support table, with respect to the sheet (2).
    [0062]
    [0063] According to one embodiment (Figures 1 and 2), the roller groups (4a) and (4b) that form the table of support are provided incorporated in the assembly between respective pairs of carrier belts (5) carriers equipped with independent drive motor drives, which allows varying the dimension of the passage (6) of the cutting fluid, even during the process of the cuts (3), thus also allowing versatility of the size of the cuts (3), without the need for prior adjustment of the machine for the cuts (3) that you want to make.
    [0064]
    [0065] However, in a simplified embodiment of a more economical nature, the groups of rollers (4a) and (4b) components of the support table can be incorporated into the assembly between a single pair of carrier belts (5), as shown in the figure 5, which is also within the scope of the invention, since it allows, keeping fixed the dimension of the hole (6), to make cuts (3) in sheets (2) accompanying the hole (6) of passage of the cutting fluid. head movements (1) cutting fluid projector.
    [0066]
    [0067] In addition, it is planned to provide a transverse conveyor belt (9), formed with a grid structure, below the cutting area, through which the fumes and small residual particles of the cuts (3) can pass, for the evacuation of said waste, while the larger pieces and pieces resulting from the realization of the cuts (3) are deposited on said conveyor belt (9), for its removal abroad, thus facilitating the collection of said resulting pieces and pieces of the cuts (3).
