Definitions

  • the present invention relates to plants for treatment of vehicle bodies of the type where a body is transported along a treatment chamber by means of a suitable conveyor.
  • the treatment may be for example of the type which uses treatment liquids sprayed onto the body, heat application, etc.
  • part of the conveyor Often in these types of plant it is preferable for part of the conveyor to be situated outside the treatment chamber, in order to prevent the conditions inside the chamber having, for example, a damaging effect on the conveyor itself.
  • the drive system of the conveyor it may be preferable for the drive system of the conveyor to be kept outside the chamber and for only the part supporting the body to be kept inside.
  • the conveyor therefore comprises elements inside the chamber and elements outside the chamber which are connected together by means of a connecting arm entering the chamber through a slot which is present in the wall of the chamber and extends in the direction of movement of the conveyor and along which the arm travels during the transporting movement of the conveyor.
  • the drawback is that the blades displaced by the arm leave exposed a relatively large opening through which the internal atmosphere of the treatment chamber may easily escape. Moreover, the force needed for elastic distortion of the blades may be relatively high and gives rise to friction which causes wear of both blades and conveyor. The blades may moreover not return fully into their closed position, for example because of interference between the edges of the adjacent blades and this may further adversely affect sealing of the system across the slot.
  • the general object of the present invention is to provide a plant of the type mentioned which ensures more efficient and reliable closure of the slot along which the conveyor arm travels.
  • an apparatus for treatment of a vehicle body comprising a treatment chamber which contains a treatment zone for treatment of the body and a conveyor carrying the body through the treatment zone, the conveyor comprising elements outside the treatment chamber and elements inside the treatment chamber, the external elements and the internal elements being interconnected by means of a connecting arm which passes from the outside to the inside of the treatment chamber through a slot which is present in the wall of the treatment chamber and which extends along the movement path of the conveyor along the treatment chamber, a sealing structure being arranged on the slot so as to close the slot and open up near the arm when the arm is moving in the slot so as to allow the movement of the arm along the slot, the sealing structure comprising a plurality of vertical elements which are arranged next to each other and have an upper end supported above an upper edge of the slot and which hang down from above so as to have

  • FIG. 2 shows a front view of a zone of the plant where there is a slot for allowing an arm of a conveyor arm to pass through, provided with closing elements according to the invention
  • FIG. 3 shows a longitudinally sectioned view of a possible structure of a single closing element
  • FIG. 4 shows a cross-sectional view of the closing elements along the line IV-IV of Figure 2.
  • Figure 1 shows in schematic form an apparatus, denoted generally by 10, for treatment of a vehicle body 1 1.
  • the apparatus 10 comprises a treatment chamber which contains a treatment zone 13 for treatment of the body and a conveyor 14 carrying the body through the treatment zone 13.
  • the conveyor 14 comprises both elements 14a outside the treatment chamber (for example a motor-driven carriage for travelling along a special external rail of the conveyor) and elements 14b inside the treatment chamber (for example a platform or a skid for supporting the body).
  • These external and internal elements are interconnected by means of a connecting arm 15 which passes from the outside to the inside of the treatment chamber through a slot 16 present in the wall of the treatment chamber.
  • the slot usually extends over the entire movement path of the conveyor along the chamber.
  • the structure of the chamber and the conveyor are known per se and may be easily imagined by the person skilled in the art and will vary in a known manner also depending on the type of treatment which the plant performs on the body. They will therefore not be further described or shown.
  • the treatment may consist for example of spray painting, drying, dip-treatment in surface treatment liquids, etc.
  • a sealing structure 17 is arranged on the slot 16 so as to close the slot and open up close to the arm when the arm itself passes along the slot during the movement of the conveyor 14.
  • the sealing structure 17 comprises a plurality of vertical elements 18 which are arranged adjacent to each other at least in the direction of extension of the slot and which have an upper end 19 which is supported above an upper edge 20 of the slot and which hang down from above so as to have a lower free end 21 which is arranged beyond the lower edge 22 of the slot, so as to be arranged transversely thereto.
  • Each element 18 of the plurality is made flexible (for example made of plastic or flexible metallic material) so as to bend when the arm passes by and allow it to travel along the slot and return into its straight condition after the arm has passed by.
  • Each element 18 of the plurality has a constant cross-section at least in a portion which extends between the upper edge 20 and the lower edge 22 of the slot, so that in this portion the adjacent elements are arranged closely next to each other and the space between the elements in this portion is thus reduced to a minimum or is virtually non-existent when they are arranged vertical.
  • the constant cross-section may advantageously extend over the entire length of the element 18 from the point where it is supported at the top to its lower free end 21.
  • the cross-section of the flexible elements is circular, although other cross-sections may be used.
  • Each element 18 of the plurality has in the proximity of its lower end 21 a density which is greater than the density which it has near the upper edge 20 of the slot, so that it is heavier close to its lower free end and is "pulled” by its free end into its straight condition hanging downwards.
  • each element may have advantageously a first density from its upper end 19 as far as a point 23 after the lower edge 22 of the slot, and a second density, greater than the first density, from this point 23 as far as the free end 21.
  • the structure according to the invention ensures that the elements are precisely and reliably repositioned next to each other after the arm has passed by and that there is a small opening caused by the presence of the arm, as schematically shown in Figure 2.
  • the arm may also have a shaped cross-section, at least in the zone where it passes through, corresponding to the arrangement of the elements in the opening zone.
  • the arm may have a cross-section which is oval with a greater vertical axis (as shown schematically in broken lines in Figure 2) or also droplet-shaped.
  • a shield 24, arranged transverse to the extension of the arm, may also be present on the arm itself, immediately behind the elements 18 so as to provide a screen towards the inside of the chamber for opening of the elements around the arm itself.
  • Figure 3 shows in schematic form a possible advantageous longitudinal cross-section of an element 18.
  • the flexible elements 18 are axially empty at least in a portion near to the upper edge 20 of the slot (preferably from their upper end as far as a point below the lower edge 22 of the slot) and are solid in a portion near to their lower end 21 .
  • the solid part 25 may be formed as one piece with the empty (tubular) part or may be formed as a plug inserted in the lower end of the element 18.
  • the plug may be easily made by casting in the hollow element 18 a suitable solidifiable material (for example plastic) with a suitable density.
  • the elements may be made entirely of plastic, entirely of metal or a combination of the two materials.
  • the flexible hollow part may be made of plastic material and the plug, or the terminal end, may be made of metal, so that there is for example a greater difference in density between the two parts.
  • the flexible elements may have a length, for example, of between 40 and 60 cm, both depending on the height of the slot to be covered, and the desired sealing action above and below the slot and the flexibility of the material used for the flexible elements.
  • the flexible elements may have a width in the direction of extension of the slot which is advantageously comprised between 1 and 5 mm, also depending on the flexibility of the material used.
  • the slot with the sealing structure may be on the right-hand side, left-hand side or on both sides of the chamber or also in other positions on the walls, depending on the requirements and/or the type of conveyor used.
