    [0002] CYLINDER TO APPLY ENGOBE ON CERAMIC PIECES
    [0003]
    [0004] Object of the invention
    [0005] The present invention refers to a cylinder for applying slip on ceramic pieces that allows to correctly apply the slip on ceramic pieces with defects in the flatness of the surfaces of their faces, so that for this the cylinder has an elastic part that is deformable, allowing an outer surface of the cylinder to be properly adjusted to the uneven surfaces of its faces. The cylinder comprises a modular structure made up of several individual modules that also improve the application of the slip, and obviously the result obtained.
    [0006]
    [0007] Technical problem to solve and background of the invention
    [0008] Currently, the rib slip is a product that has been used for decades in the ceramic sector.
    [0009] oven caused by the direct contact between the ceramic rollers and the pieces during the firing process of said pieces inside the oven.
    [0010]
    [0011] This direct contact contaminates the ceramic rollers with the enamels and generates rings on the ceramic rollers; where said rings generate deformations in the pieces causing irregular curvatures (incorrect planarities).
    [0012]
    [0013] Another drawback of direct contact is that the pieces are mounted on top of each other inside the furnace, causing due to the weight of the ceramic pieces / rollers, the breakage of said ceramic rollers producing a "barrack."
    [0014]
    [0015] In the market there are various rib slitter machines, but they are not effective, since they do not completely homogeneously enlighten the entire rib and sometimes contaminate the upper part of the ceramic piece (tile) causing losses in production.
    [0016]
    [0017] An incorrect application of the engobe of rib, supposes for the company big economic expenses, forcing to stop the production and to carry out a maintenance of the oven; it is also necessary to clean or change the ceramic rollers.
    [0018] Other drawbacks of known gumming machines are the following:
    [0019] - Difficulty adapting the width of the roller applied by the slip to the different manufacturing formats.
    [0020] - Difficulty in applying the slip in areas where the flatness of the ceramic piece has been lost, either due to its own design or previous manufacturing processes, so that in these cases the ceramic piece has been slightly deformed, and as a consequence of this in certain areas the rib is unslipped.
    [0021]
    [0022] Description of the Invention
    [0023] In order to achieve the objectives and avoid the drawbacks mentioned in the previous sections, the invention proposes a cylinder for applying slip on ceramic pieces that includes an external surface configured to apply the slip on the ceramic pieces during the rotation of the cylinder by contact of said outer surface on the ceramic pieces.
    [0024]
    [0025] The cylinder of the invention comprises at least one individual module that includes an annular body of circular shape, a core and an intermediate body of elastic structure that joins the annular body to the core; where the annular body is deformable and includes the outer surface.
    [0026]
    [0027] The elastic structure of the intermediate body is deformable and is configured so that during the application of the slip on the ceramic pieces, the outer surface of the individual module can adapt to flatness irregularities of the surface of the ceramic pieces on which the slip is applied.
    [0028]
    [0029] The intermediate body comprises spokes having internal ends attached to the core and external ends attached to the annular body. In one embodiment of the invention, the spokes of the intermediate body comprise a straight configuration, and in another embodiment of the invention the spokes of the intermediate body comprise an arcuate configuration.
    [0030]
    [0031] When the cylinder of the invention comprises several individual modules arranged in the same axial direction, intermediate separating spaces that separate said adjacent individual modules are preserved between adjacent individual modules. avoiding contact between them, where said individual modules are coupled in a central axis.
    [0032]
    [0033] The intermediate separation spaces are preserved by means of separator elements that are also coupled around the central axis in coincidence with areas of confluence of the adjacent individual modules.
    [0034]
    [0035] In an embodiment of the invention, the spacer elements comprise sealing gaskets housed in annular recesses located in the central axis.
    [0036]
    [0037] The intermediate bodies of the individual modules have a smaller width than the annular bodies of said individual modules; where this difference in width generates cameras between adjacent individual modules.
    [0038]
    [0039] In an embodiment of the invention the intermediate gaps between adjacent individual modules comprise a width with a distance between one and five millimeters.
    [0040]
    [0041] The core of each of the individual modules includes a hole configured to introduce the central axis.
    [0042]
    [0043] The annular body of each individual module comprises an elastic structure, such as an elastomeric material, without ruling out other materials.
    [0044]
    [0045] Below, to facilitate a better understanding of this specification and forming an integral part thereof, a series of figures is attached in which the object of the invention has been represented by way of illustration and not limitation.

    [0055] Description of an embodiment of the invention
    [0056] Considering the numbering adopted in the figures, cylinder 1 for applying slip 13 on ceramic pieces 7 comprises individual modules 1a that are inserted in a central axis 2 to form the desired length of cylinder 1, which can be formed by a single module individual 1st or by several individual modules 1st.
    [0057]
    [0058] Each individual module 1a comprises an annular body 3 of circular shape made of elastomeric material, a core 5 and an intermediate body 6 that joins the annular body 3 with the core 5; where the annular body 3 includes an outer surface 4 applying the slip 13 and where the core 5 is configured to be able to fit each individual module 1a in the central axis 2 that fits inside a hole 5a of the core 5.
    [0059]
    [0060] The intermediate body 6 comprises elastic radii, which are configured to be able to deform during the contact of the outer surface 4 of the cylinder 1 on the surface or rib of the ceramic tile 7 proportionally to the deformation of said ceramic tile 7, allowing the contact surface 4 of the engobe 13 in its entirety contact the area of the surface to be coated of the ceramic piece 7.
    [0061]
    [0062] To improve the adaptation of the outer surface 4 of the cylinder 1 on the surface of the ceramic piece 7, in an embodiment of the invention the elastic radii of the intermediate body 6 comprise an arcuate configuration; where inner ends of the elastic spokes are converging towards the center of the core 5 and outer ends, opposite to the inner ends, are diverging outwards.
    [0063]
    [0064] In another embodiment of the invention, the elastic spokes comprise a straight configuration.
    [0065]
    [0066] On the other hand, when cylinder 1 of the invention comprises several individual modules 1a, its mounting is done in such a way that an intermediate gap 8 is preserved between the adjacent individual modules 1a, essentially with a gap width between 1 and 5 mm. to compensate the deformation of the annular body 3 when it presses on the rib or surface of the ceramic tile 7 for the application of the slip 13. In the absence of said intermediate space 8, the different individual modules 1a would rub against each other reducing their elastic capacity creating a zone or more rigid interface, with which the application of engobe 13 would be defective.
    [0067]
    [0068] To achieve the intermediate spaces 8, between the adjacent individual modules 1a of the cylinder 1 there are included spacer elements 9 that are coupled around the central axis 2 in coincidence with areas of confluence of the adjacent individual modules 1a of the cylinder 1.
    [0069]
    [0070] In the embodiment shown in Figure 7, the spacer elements 9 comprise sealing gaskets, and more specifically they are O-rings housed in annular recesses 9a located in the central axis 2.
    [0071]
    [0072] In order for the slip 13 to flow properly inside the cylinder 1 when the annular body 3 of said cylinder 1 is immersed or comes into contact with the slip 13 housed inside a bowl 12 so that said annular body 3 of cylinder 1 is impregnated with In the slip 13, the elastic spokes of the intermediate body 6 are placed in a resting position without tension, because during said impregnation of the slip 13 housed in the tray 12, the elastic spokes are not subjected to any stress.
    [0073]
    [0074] This characteristic favors the cylinder itself to act as a stirrer for the slip 13 (an important function to maintain the homogeneity of the slip), which is undoubtedly an additional advantage to the point that under certain conditions of temperature, humidity, etc .; it will not be necessary to include a proper agitation mechanism as conventionally occurs.
    [0075]
    [0076] The intermediate body 6 has a smaller width than the annular body 3, so that this difference in width generates separation chambers 10 between adjacent individual modules 1a; where said chambers 10 substantially improve the passage of the slip 13 allowing it to flow better and also improves its agitation; all this translating into a better application of the engobe 13 on the ceramic pieces 7.
    [0077] During the application of the slip 13 on the ceramic part 7 through the cylinder 1, the outer surface 4 of the annular body 3 comes into contact with the ceramic part 7 by pressing lightly on it, so that as a reaction to said pressure and also due to the weight of the ceramic piece on the cylinder 1, some of the elastic radii of the intermediate body 6 flex and deform thanks to the elasticity of said elastic radii, thus maintaining a slight controlled pressure between a section 3a of the outer surface 4 of the annular body 3 and the surface of the ceramic tile 7 to be impregnated with the slip 13.
    [0078]
    [0079] During the application of the slip 13 on the outer surface 4 of the ceramic part 7, as shown in figure 6, the section 3a of the annular body 3 that is in contact with the ceramic part 7 is also deformed; where said section 3a of the annular body 3 corresponds to the deformed elastic radii that flex during said contact on the ceramic piece 7.
    [0080]
    [0081] Furthermore, it should be noted that the elasticity of the intermediate body 6 together with the elasticity of the annular body 3, allow the outer surface 4 of said annular body 3 to be perfectly adapted to the entire ceramic tile surface 7 to be impregnated, although said surface presents irregularities of flatness.
    [0082]
    [0083] During the application of the slip 13 on the ceramic part 7, the cylinder 1 rotates in combination with the advance of the ceramic parts 7 that are dragged by means of a roller transport system 14, where said ceramic parts 7 are in contact with the outer surface 4 of cylinder 1 and where said ceramic pieces 7 rest on the outer surface 4 of cylinder 1; all this as shown more clearly in figure 6. Said outer surface 4 of cylinder 1 can include an engraving 11 to then apply it on ceramic piece 7.
    [0084]
    [0085] In said figure 6 and also in figure 5, a slipping machine is shown that includes the cylinder 1 of the invention, as well as the bucket 12 containing the slip material 13, and the transport system 14 for dragging the ceramic pieces 7 in combination with the rotation of cylinder 1; where a lower part of the cylinder 1 is submerged within the slip material 13.
    [0086] The slipping machine further includes an adjustable device 15 that supports a laminar body 16 (racla) located in parallel and in proximity to a part of the outer surface 4 of the annular body 3 of cylinder 1, so that during the rotation of cylinder 1, the slip 13 is dragged by the outer surface 4 of the cylinder 1 adjusting the thickness of the slip layer 13 to the space existing in said outer surface 3 of the cylinder 1 and the sheet body 16.
