Definitions

  • the present invention relates to a continuous-cycle painting booth inclusive of the drying step, suitable to mass- products or single articles made of wood or other materials which need to be spray painted.
  • the painting booths of known type which have the same object as the booth in reference are provided with a product transport device extending either in a horizontal plane on the floor or the ceiling or in a vertical plane on a wall.
  • a product transport device extending either in a horizontal plane on the floor or the ceiling or in a vertical plane on a wall.
  • the object of the present invention is to remarkably reduce the overall spaces necessary to the installation of a booth without however reducing the total production capacity of the equipment, being eventually possible the installation of several painting stations along the path followed by the product to be painted without remarkably increasing the overall bulkiness.
  • a further object of the invention is to make the painting station much simplier, reducing the number of nozzles to the minimum while ensuring a perfect evenness of the paint coating.
  • a continuous cycle painting booth characterized in that it comprises: a product transport device consisting of an endless flexible chain extending along parallel trajectories, in turn lying on a plurality of parallel floors, said chain being composed of a number of links provided with idler rollers pivoted outwardly of the links through a pin acting as a support for the product to be painted; means adapted to impart said chain a uniform rectilinear movement; at least a spray painting station located on the path of said chain in which a powered belt is provided which is adapted to impart the number of idler rollers a rotatory movement about their own axes during the displacement of the chain.
  • the booth according to the present invention also has the advantage that, with respect to known booths, it allows to save about 90% of the surface that may be trampled.
  • a further advantage resides in that the booth can be assembled on a structure made of metal section members completely fitted together already in the workshop and therefore transportable in one block, unlike the known art booths which, being very bulky, are not transportable in one block and need to be assembled in situ.
  • the painting booth inclusive of the drying step substantially consists of a metal support structure 1 supporting a transport device for the products to be painted, globally identified at 4.
  • the transport device 4 extends continuously according to horizontal storage levels that are mounted parallelly one above the other on the metal structure 1.
  • the transport device substantially comprises a chain completed with idler rollers or disks made of nylon 3; the lower rollers perform the function of sliding shoes and are shaped so as to reduce the sliding friction on chain-holding guides 6, consisting of a metal channel whereas the upper idler rollers 3, coaxial with the lower ones, support respective pins 2 having the function of carrying the pieces to be painted 7.
  • a loading area 11 for the workpieces 7 is seen which is provided with an automatized or manual pneumatic system not shown, in which the workpieces 7 are fitted on the support pins 2 of the transport chain 4.
  • the chain through a system consisting of steel idler wheels 5, reaches a painting station 13 and at the outlet of said station it extends to a first upper storage and drying level 15 and, through an idler wheel 9 also performing the function of taking up the chain, enters the first storage level shown in Fig. 5.
  • the chain following its trajectory, travels over many parallel right lines and goes on through a series of idler wheels 5, as far as it ascends to the higher storage floor 15, but this time the ascent takes place on the side opposite the preceding one, that is on the side of the machine, as seen in Fig. 5.
  • the transport chain 4 again- travelling over many parallel right lines, forms a new store, till it comes to one of the driving wheels 8 from which it starts the ascent to the upper storage level 15" passing through the respective idler and takeup wheel 9.
  • the painting stations may be more than one and located at different points, in order to carry out, for example, first an undercoating and then a finish painting. Should the workpieces, at the end of the drying time, need a further processing, they could pass again over the same painting station for the application of a further paint coat, without the manual intervention of an operator.
  • the movement of the transport chain 4 is transmitted through the driving wheels 8 pivoted on, and made integral to each other, by a shaft 19 connected to a starter and geared motor unit 18 which directly transmits the motion to the ascent and indirectly, through the chain 10 provided with a takeup 50, transmits the motion to the drive shaft 20 on which the idler wheels 9 for the descent are pivoted.
  • the transport chain 4 passes through a fixed chain-guide 25 holding it in line without allowing it to contact the nylon rollers 3 on which the pins 2 are integrally mounted, on said pins 2 being in turn fitted the products to be painted 7.
  • a rotating movement is imparted to the nylon rollers 3 through a powered belt 26 made of rubberized canvas, which is kept in contact with the rollers 3 by a belt-pressing device 27.
  • the belt 26 imparts the nylon rollers 3 a rotatory movement about their own axis and, as a result, a like movement to the pins 2 and to the workpiece 7 to be painted.
  • the direction and speed of movement of the rotation belt 26 which movement takes place through nylon driving and idler pulleys 28, can be varied so as to allow the best exposure of the workpiece 7 to the painting nozzles 30.
  • the painting operation is governed by a pneumatic device 29 which, by means of an intermittence rod 32 detects the presence of the pins 2 and operates the nozzles 30 in automatic spray guns 30 controlled by a pneumatic system; said nozzles 30, parallelly and intermittently, send paint jets to the workpieces 7.
  • the nozzles 30 of the automatic spray guns controlled by a pneumatic system can be connected, like a common gun, to a reservoir under pressure or to a pump.
  • the nozzles 30 remain in a fixed position over the whole working cycle, since the exposure of the workpieces is adjustable and ensured by the above described exposure system.
  • the pneumatic device 29 and the rod 32 it is possible to adjust the moment and duration of the painting jet by merely moving the rod 32 away from or closer to the transport chain 4.
  • the painting according to the production requirements, can be made continuous if the pulses of the pneumatic control 29 are eliminated.
  • the painting station is provided with a conveyor 31 equipped with an appropriate exhauster adapted to suck the painting fumes and to convey them to the outside through vent stacks made of galvanized sheet iron, not shown.
  • a sloping wall 33 which has the function of protecting the chain from the jets of the nozzles 30.
  • the chain extends along a path comprising parallel trajectories lying in turn on a plurality of honzontal parallel levels or floors; it is however clear that the plurality of parallel levels might also be disposed in a vertical direction without departing from the spirit and scope of the invention, as defined in the appended claims.
