Definitions

  • the invention is a semiautomatic machinery with options for total automation which can be used to refine flat surfaces of wood panels or other materials (e.g. metal, glass, fibreglass, plastic).
  • the machine fits the market of finishing panel machines for small and medium-size companies.
  • the finishing work such as calibration, spray painting, smoothing, polishing, rustication, sanding, etc., done by artisans who treat small/medium volume of material, is hand-made. Alternatively it is done by using specific portable equipment for each type of treatment. This approach limits the manufacturing and the product quality, since in order to obtain a good result a continuous and homogeneous movement is needed. Therefore such a manual process cannot guarantee high quality products.
  • finishing process especially High Gloss finishing, are carried out as described below. After the first painting stage (priming), the sanding of the treated surface is completed, followed by the second (or third) painting stage. In order to obtain this type of finishing a three-step process is needed:
  • this three-step manufacturing process is normally performed by using in line machines, at least one machine for each single step. So the daily production reaches a large number of processed panels in terms of square meters.
  • the technical problem solved by the new machinery is to perform automatically or almost automatically the sequence of stages described above. In this way time is saved and the finishing quality of the product is improved, increasing the value for money. Therefore the new equipment and the related investment, suitable for small and medium-size companies, guarantees them to make an high quality finishing work. At present such a process is manually done by artisans with poor quality results. Alternatively the small artisans turn to the big company in order to get high quality finishing work.
  • the machinery object of industrial invention, is the only one in the market that combines the manual work of the abrasive belt with the automatic movement of the tangential brush. Moreover it is possible to insert an angle gearbox on the tangential brush to allow even the head work.
  • this machinery ( Figure 1 ) is the only one in the market that can realize the High Gloss Finish (super deep gloss) and many other processes suitable not only for wood but also for steel and other materials. At present the small and medium-size companies make that kind of finishing work with portable equipments, operating a series of subsequent steps.
  • the machinery is made up of three basic parts.
  • the machinery agrees with the Machinery Directive of the DIRECTIVE 2006/42 / EC and is equipped with appropriate safety systems related both to the presence of moving parts and to the suction systems.
  • the machinery is equipped with metal protectors to prevent contact between the operator and the moving parts. These protections affect the abrasive belt, the brush unit and the driving pulleys.
  • an emergency stop button (mushroom head button) is placed on the control panel. It allows to stop the machinery and block all the operations.
  • the machinery is also equipped with an emergency cord with a locking mechanism similar to the emergency button. The cord is placed in front of the operator along the main working line. When the cord is pulled, the safety switch is immediately activated and the machinery is stopped.
  • the suction system is composed by two suction nozzles connected to the intake system installed the production site. The two nozzles are placed on the driving pulley and on the brush unit.
  • FIG. 1-7 shows the main characteristics of the machinery:
  • the invented machinery can be used for surface treatments like sanding, glazing, smoothing, polishing, etc. of many materials including glass, metal, plastic, aluminum, brass etc. Particular attention is paid to the wood material and the creation of High Gloss Finish treatment (super deep gloss).
  • High Gloss Finish treatment super deep gloss
  • the small company usually turns to large specialized companies or alternatively use single portable machines. This is the niche market where the new machinery is positioned by creating a good mix between manual and automatic process.
  • the new machinery combines the advantages of manual and automatic work, the first characterised by the supervision of the operator who controls any defects and impefections on the workpiece that need to be once more worked (feature that cannot be done in the automatic line), the second guarantees the homogeneity of the work such as a smooth blemish-free finish.
  • the production obtained with the new machinery is about 30 square meters per day (8-hour cycles), that is, in term of surface, the equivalent panels used in about 2 or 3 kitchens.
  • the quality of the finished product is higher than the quality of the product made with portable equipment.
  • the automatic line which is not yet economically suitable for small companies
  • the three processes are carried out with the constant supervision of the operator. This is essential in order to obtain a good finished product.
  • the final quality depends on the correct execution of each stage. It is worth pointing out that in many countries where High Gloss Finish has not yet arrived or it is going to arrive, this machinery can be used as start up and training equipment.
