Definitions

  • the present invention deals with glass coating using a nanoscale structured lacquer composite of inorganic metal oxides, binder solvent-based, inorganic pigment for colour inclusion to product to improve on coating formulation and creating a suitable coating (product) for glass materials to achieve high temperature curing characteristics, self-levelling ability after coating onto glass surface, improvement of glass scratch hardness, reduction of visible infrared heat (both near and far) and induced heat transmission through the product coating, reduction of light permissible light reflectance through the glass materials, improvement of light transmission through the coated glass material as well as the reliability of the coating on the glass material (lifespan). It has a certain viscosity, thickness and dispersion characteristic to be suitable to bond together with the glass surface in order to create a long lasting coating structure with the glass material.
  • the product is uniquely identified as a new creation and process to cater for both "on line” and “off line” coating process during actual production as it can be implemented during the glass making process in molten stages till after formation at high temperature, or afterwards when the glass materials are cooled to a certain temperature before coating can take place.
  • the chemistry formulation is specially designed to suit both these 2 processes depending on production needs and requirements.
  • the description will highlight the various processors or modules needed to complete the "off line” production state of technology together with the product requirement and characteristics as a combinatio is required in order to successfully implement the module to work for the product to be coated and cured using the various modules for the production.
  • the "on line” production state of technology will describe and only require 2 indicated modules during the glass making process compared to "off line” which glass materials are already been created and afterwards going through 7 indicated modules to allow coating and curing of the coating onto glass materials.
  • Stage 1 The raw glass is loaded on the conveying system by means of the loading module.
  • Stage 2 The raw glass will be going through the cleaning module to remove impurities, excessive oil and grease stains and to create high energy / adhesion surface tension to suit chemical coating.
  • Stage 3 Special process application for layer coating to allow uniformity coating onto glass material.
  • the coating module will apply the special chemical with a controlled thickness to the glass. This process must be done under clean room conditions in order to avoid any kind of particles to contaminate the glass surface before, during and after the coating.
  • Stage 4 The coated surface undergo the curing and cooling module to allow full bonding of the coating with the glass material in order to reach a dry and hard condensed state and to achieve a strong bonding with the glass.
  • Stage 5 The visual appearance of the coated surface is analyzed by a quality check module using pulse capture data from the camera installed.
  • Stage 6 The fully coated and cured glass material is unloaded from the conveying system by means of the unloading module to be packed later.
  • the overhead stacker After the PLC system sends a ready signal to the loading module, the overhead stacker approaches the stack of glass sheets on the A-frame structure and applies its suction cups to the first sheet of glass. A depression is created inside of the suction cups, attaching the sheet of glass to the overhead stacker. The overhead stacker then moves with the glass to its position between the rollers of the conveyor. To release the sheet of glass on the roller conveyor, the depression in the suction cups is cancelled. After the sheet of glass has moved to the next station, the roller conveyor over the overhead stacker is free and a new cycle of loading can begin.
  • the glass is rinsed in the first section of the machine to flush away the biggest particles and to wet the glass for the next step. Then the glass goes through a scrubbing section where rotating round scrubber fully polish its top surface in a sinusoidal movement. After that the glass goes through three sections where cylindrical brushes finish to clean the surface. Finally the glass is dried by means of air-jets placed in a way to optimize the drying even at high transport speeds.
  • the coating module must be applied on the glass as a wet film with a controlled thickness. This is done by a special coating device. This process needslo be done in a controlled environment to avoid any deposition of foreign particles on the glass surface before, during and after the coating. A clean room must enclose the area between washing (2) and curing (4) to achieve this.
  • the curing is done by heating the coating and the glass in an oven. Therefore the coated glass is moved in a heating tunnel where it is dried in a controlled process. After that the glass needs to be cooled down to room temperature in a controlled process, so that it can be handled and packed after the final quality check. This is done in a cooling tunnel where a forced air circulation by means of ventilators cools the coated sheets of glass down.
  • a spectrophotometer is moved in cross direction to the glass taking measures and comparing these to a predefined range of values. If the measure gets out of this predefined range, an alarm is given through the PLC communication system to the operator.
  • Another overhead stacker placed between the rollers of the last roller conveyor awaits a sheet of glass.
  • the sheet arriving is stopped in the accurate position, approached smoothly from the bottom by the overhead stacker which applies its suction cups to it.
  • the ensemble moves to a quasi-vertical position where the glass sheet is released on a dedicated A-frame structure. There the glass is ready to be packed.
