Definitions

  • the present invention relates to the formation of sheets of tesserae of mosaic designed to be laid for the decorative coating of mural structures, floors, pavements, and the like.
  • Sheets of this sort normally have standardized dimensions, and the number of the tesserae of each sheet, arranged in orderly fashion to form a chequered pattern, is evidently correlated to their dimensions. For example, with square tesserae having side of 2 cm, each sheet, which is also square, may include typically 15 rows by 15 columns of tesserae.
  • the tesserae of mosaic are initially located within the trays with the respective front decorative faces, i.e., the faces that in the condition where the sheets are laid will be in view, facing upwards to enable visual verification of the integrity thereof.
  • the groups of tesserae of mosaic thus composed are turned over so as to position the base or back faces of the tesserae upwards.
  • the joining adhesive is then applied from above on the back faces of the tesserae, normally using a mechanized dispenser that is equipped with nozzles for dosage of the adhesive and can be displaced according to paths corresponding to the rows and columns of tesserae.
  • a flexible covering sheet of anti-adhesive material typically siliconed paper.
  • the sheets of tesserae of mosaic are picked up from the corresponding trays and then transferred into packaging boxes.
  • the adhesive applied from above while it is still hot and in the fluid state on the back faces of the tesserae can penetrate into the areas of intersection between contiguous tesserae and, particularly in the case of tesserae of small thickness, can become visible on their front faces with evident aesthetic drawbacks.
  • a further drawback of this methodology lies in the difficulty of managing and checking the thickness of the adhesive applied from above and in particular the homogeneity of height in so far as, once deposited and exposed to the ambient atmosphere, the adhesive immediately starts to solidify. Notwithstanding the use of squeezing and levelling rollers, at the end of its application, stretches of adhesive having different contact times with the atmosphere will have different hardening times before being subjected to the action of the rollers, with consequent lack of uniformity.
  • a second type of methodology which also envisages initial insertion of the tesserae into the containment trays with the corresponding front faces facing upwards.
  • Each tray containing the tesserae can then be inspected visually to check the integrity of the corresponding front faces, and is then turned upside down so as to place the tesserae in a second tray in order to position the back faces thereof upwards.
  • the next step is the operation of gluing, which envisages providing a sheet of paper rendered anti-adhesive and cut to size and positioning it on top of a device for dispensing the adhesive equipped with nozzles for delivering the adhesive from beneath upwards against the under face of the sheet of paper, also in this case according to a predetermined path.
  • the sheet of paper is deposited against the back faces of the tesserae of mosaic positioned in the underlying containment tray, thus obtaining mutual joining thereof.
  • the sheet is then pressed with a constant pressure against the back faces of tesserae so as to obtain a homogeneous thickness of the adhesive applied.
  • a further drawback of this type of process lies in the impossibility of verifying visually that all the tesserae of mosaic adhere properly to the sheet of paper with the adhesive and, also in this case, that the front faces of the tesserae themselves remain intact at the end of the gluing step.
  • An object of the present invention is to overcome the drawbacks of the current methodologies and more in particular to provide a process for formation of sheets of tesserae of mosaic, as well as a system for implementation of the process, which will enable the operation of turning over of the tesserae of mosaic prior to the gluing step to be avoided, eliminating both the need for resources and the problems that derive therefrom.
  • Another object of the invention is to provide a process and a system for the formation of sheets of tesserae of mosaic that will enable a constant and efficient visual check of quality to be obtained before, during, and after the gluing step, thus ensuring the quality of the sheets of tesserae of mosaic formed and at the same time increasing efficiency and productivity by reducing or even eliminating the production of defective sheets.
  • the above objects are achieved thanks to a process of the type defined in the preamble of Claim 1, the peculiar characteristic of which lies in the fact that the step of joining envisages application from above of the glue on an anti-adhesive substrate and positioning of the group of tesserae on the glue applied on said anti-adhesive substrate, keeping the front faces of the tesserae facing upwards so as to cause the glue to adhere to the back faces of the tesserae.
  • the anti-adhesive substrate is constituted by a regenerable endless belt.
  • the anti-adhesive substrate can be constituted by a discrete flexible plate.
  • the system is moreover provided with a series of visual-inspection stations, not illustrated in detail in so far as they are within the reach of the person skilled in the branch, typically constituted by video cameras operatively connected to a pre-programmed image-processing system for comparing the images detected with reference images and verifying the congruity thereof.
  • the video cameras will be positioned in such a way as to film both the groups of tesserae of mosaic each time located in the corresponding containment trays 2 as they advance on the conveyor 1, and the area of application of the adhesive on the anti-adhesive substrate, constituted, as has been said, by the belt 6 or alternatively by the plates 10 each time positioned thereon, as well as the sheets F subsequently transferred to the packaging line 11.
  • the tesserae of mosaic are, as has been said, positioned within the respective containment trays 2 in an orderly way to form a chequered pattern, with the corresponding front faces facing upwards. Then, whilst the trays 2 are transferred from the feeder 1 to the area where the manipulator robot 8 picks up the tesserae, the corresponding front faces are inspected by the video-camera system so as to verify not only the correct positioning thereof but also the absence of surface defects or anomalies.
  • the gluing robot 3 proceeds to application of the fluid adhesive on the anti-adhesive substrate constituted by the surface of the regenerable belt 6 or, alternatively, by the plates 10 each time deposited thereon.
  • the adhesive is applied by the dispenser robot 4 from above downwards and in a generally conventional way according to paths defining a grid - either continuous or in stretches - corresponding to the arrangement in rows and columns of the groups of tesserae within the corresponding containment trays 2.
  • the manipulator robot 8 picks up, via the corresponding suction device 9, each group of tesserae 2 from the corresponding containment tray 2 on the feeder 1 and transfers it onto the grid of adhesive just applied on the anti-adhesive substrate.
  • the group of tesserae is then deposited, in the same configuration in which it has been picked up, i.e., with the front faces of the tesserae facing upwards, on the grid of adhesive, thus obtaining joining therewith of the corresponding back faces.
  • each sheet F thus formed is picked up from the belt 6 by the same manipulator robot 8 and then transferred to the packaging line 11 for being boxed.
  • the tesserae of mosaic remain constantly oriented with the corresponding front decorative faces facing upwards. This enables the system of visual inspection to check constantly not only the presence and correct positioning of the tesserae but also the integrity and the absence of surface defects of said front faces, together with proper dispensing of the adhesive each time applied on the anti-adhesive substrate.
  • each sheet F will be constituted only by the tesserae and by the grid of adhesive that joins the back faces thereof in the case where the anti-adhesive substrate is constituted by the surface of the regenerable belt 6, or else will include also the plate 10 in the alternative case where this is used for constituting the anti-adhesive substrate.
  • an auxiliary anti-adhesive plate may then be inserted, with separating function, between each sheet F each time introduced into the box 12 along the packaging line 11 and the underlying sheet F.
