Definitions

  • the present invention refers to the field of plants for painting and drying vehicle bodies, and in particular its object is a drying group in plants for drying paints and/or other materials.
  • the drying plants for paint applied to vehicle bodies generally comprise a tunnel-shaped room in which a structure with a mobile scaffolding is arranged, such structure being formed by vertical uprights up against the walls of the room and side guides supported by such vertical uprights, on which slides for moving a central beam are arranged. Slides are arranged on the side guides for moving a central beam.
  • the latter constitutes the support of a drying device consisting of three flat groups of drying panels (in each group the panels are adjacent to one another and side by side). Such a device is fixed to a carriage which translates along the central beam.
  • each panel can actually consist of a set of distinct single panel elements.
  • the central panel As far as, in particular, the central panel is concerned, it can be moved together with the entire central beam of the scaffolding in the direction (defined here as direction X) of longitudinal development of the cabin; moreover, it can translate along the direction of development of the central beam itself (defined here as direction Y). In addition to these motion a vertical translation must then be added(direction Z) which allows for the panel to be brought closer to the top portion of the vehicle, and possibly a rotation of a part of the panel (or of some of the elements that form it) around an axis (parallel to the direction Y) transversal to the cabin, allowing said part to be tilted so as to follow the profile of the vehicle or even to be arranged vertically so as to approach the front or rear side of the vehicle.
  • the object of the present invention is to provide a drying group which, thanks to a new configuration of the support/actuation means of the panel, is able to achieve unexpected advantages in terms of constructive simplicity and flexibility of use.
  • drying group in plants for drying paints and/or other materials according to the invention, to be associated with a beam of a support scaffolding, the group comprising:
  • the invention can be used in a plant for drying paints and/or other materials, not shown, housed inside a cabin and comprising a support frame of the type with a mobile scaffolding along a longitudinal development direction of the cabin, hereafter indicated as front direction X.
  • An upper beam of the scaffolding slidingly supports, along a direction Y, a carriage 1, comprising a plate 1a from two opposite sides of which brackets 1b project downwards, said brackets being provided with rollers 2 for rotational engagement with a guide, not represented.
  • a table 3 adapted to rotate with respect to the carriage 1 around a swinging axis Z is connected on the lower face of the plate 1a.
  • the rotary table 3 supports, through an articulated parallelogram mechanism or pantograph 4, a profile 5 for the suspension of a drying panel 6, for example and typically of the infrared radiation emitting type ( figure 2 ).
  • Both the profile 5 and the panel 6 (or group of panels), extend along the direction Y, and the pantograph mechanism 4, with its closing/opening movement, is suitable for causing the panel 6 to be lifted and lowered along the axis Z.
  • the panel 6 is also mobile with respect to the profile 5, and more precisely it is able to rotate around an axis Y' parallel to the direction Y and passing through two brackets 5a projecting downwards from respective ends of the profile 5.
  • a motor 7, mounted on one of the brackets 5a, is intended for the actuation of such a rotation of the panel 6, which according to the invention is carried out, thanks to a suitable support system, by covering an angle of up to 240°, between -120° and +120° with respect to a zero position corresponding to a horizontal configuration, facing downwards, of the drying surface 6a (again see figure 2 ).
  • the pantograph mechanism 4 extends, as mentioned, from said lower face 3a, said mechanism preferably comprising, like in the example, four upper arms 41, diverging and opposite one another two by two, rotatably connected to projections 12 extending downwards from the table 3, and four lower arms 42, also in this case in pairs, articulated at the lower ends of the upper arms 41 inside them, converging downwards and hinged to a central area 5b of the profile 5.
  • the actuation of lowering and lifting the assembly of the profile 5 and the panel 6 and, contextually, of opening and closing the mechanism 4, respectively, is controlled by a second geared motor 13 fixedly attached to the lower face 3a of the table 3 with the drive shaft perpendicular to that of the first geared motor.
  • the second geared motor cooperates with a winch 14 for winding/unwinding a cable, not represented.
  • a cable engages with a transmission system comprising two pulleys 15 partially represented and visible only in figure 6 and thus vertically reaches the central area 5b of the profile 5, winding around a further pulley 16 that is supported in a rotatable manner by the same profile ( figure 7 ). From the pulley 16 the cable thus vertically rises back towards the table 3 hooking to it with an end opposite the winding end, at a fixing point which is not visible.
  • Lower 17 gear means 17 operatively connect the profile 5, lifted by the aforementioned winch-pulley-cable system, to the lower arms 42 of the pantograph 4, while upper gear means connect the upper arms 41 to the table 3.
  • the lower engagement means 17 comprise two trains of toothed pinions 171, 172, rotatably supported by the profile 5 on respective sides of the pulley 16.
  • Each train comprises two end pinions 171a, 172a fixedly attached to respective ends of the lower arms 42 and that can engage with two idle pinions 171b, 172b, arranged centrally.
  • the upper engagement means 18 comprise two trains of pinions 181, 182, in this case spaced correspondingly to the mutual distance between two parallel and side by side upper arms 41.
  • the toothed pinions 181, 182 are indeed rotatably supported by the aforementioned projections 12 and comprise end pinions 181a, 182a fixedly attached to respective ends of the upper arms 41, and central idle pinions 181b, 182b acting as idle wheels.
  • the actuation of the winch 14 in the direction that causes the cable to wind around it corresponds to a shortening of the cable itself that causes the profile 5 and panel 6 assembly to be lifted.
  • the engagement means ensure that the pantograph follows the translation from top to bottom, keeping the necessary support action with a balanced configuration.
  • the gear trains according to the depicted embodiment offer the advantage of reducing the bulk in height, making a more compact group, exploiting, moreover, the large space available in the longitudinal development direction of the panel 6.
  • the swinging movement i.e. the rotation around the axis Z, that involves the entire group starting from the table 3, obtains a substantial structural and operational simplification, offering suitable performance at the same time.
  • a drying device having a single panel or group of drying panels side by side, which can change their orientation and perform all the drying functions that in plants are carried out by three groups of panels oriented in an upside-down U configuration with respect to each other.
  • the panel of the invention can be arranged horizontally to dry the horizontal parts of the body (hood, roof), or vertically and diagonally upwards (thanks to the mentioned rotation around the axis Y'), in various orientations controlled by the swinging, to dry for example the rear part of the vehicle, or a side, or even surfaces and elements beneath the lower door protector belt of the vehicle, all with high-pass speed, also considering that the greater length of the group of panels is consistent with the length of the vehicle, with all of the useful drying surface transiting in front of the area to be dried, and therefore, less exposure time is necessary per unit of drying area.
  • the outermost ones can also be articulated with respect to the others by a desired angle, so that it is possible to obtain configurations of the group of panels so that angle parts of vehicle bodies or even more extended parts equipped with a double opposing angle, like for example the entire mud guard of the vehicle including the lateral end fittings, can be dried.
  • the power (supply) and control system can be per se traced back, or obviously worked out, from what is already known in the field.
  • the invention is not limited to the embodiment described and illustrated above, and comprises any variant thereof within the scope of annexed claim 1.
  • the systems for actuating the swinging and the raising movement can be constructively different, in an equivalent functionality.
