Definitions

  • the present invention concerns to the field of varnishing and drying plants for bodies of vehicles, and in particular it refers to a positioning system for a drying device in a varnish and/or other material drying plant.
  • drying plants for drying varnishes applied to vehicle bodies generally comprise a tunnel-shaped cabin in which a movable scaffolding structure is arranged formed by vertical uprights up against the walls of the cabin and side guides supported by such vertical uprights. 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.
  • the drying device 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, the device can translate along the direction of development of the central beam itself (defined here as direction Y).
  • direction Z a vertical translation
  • the central group of panels there are also, only for the central group of panels, a vertical translation (direction Z) which allows for the upper panels to be brought closer to the top portion of the vehicle, as well as a rotation around an axis (parallel to the direction Y) transversal to the cabin, allowing the central group of panels 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 operative drying steps of the body of a vehicle are carried out in a substantially semiautomatic fashion.
  • the vehicle is positioned inside the cabin.
  • On a side wall of the cabin there is a metric scale which extends in the longitudinal direction that indicates the distance from a "zero" point.
  • the vehicle is positioned inside a range "zero to maximum distance" measured on such a metric scale.
  • the movable scaffolding is made to translate from a point behind the vehicle measured on the metric scale to a point in front of the vehicle.
  • the translation command is given by a worker who inputs, through a keypad, the numeric values of such end points inside a control station.
  • the estimation of these points is given by a visual reading: the worker roughly verifies by the eye which are the values nearest to the front and back ends of the vehicle.
  • the worker again through visual reading with reference to the metric scale positioned on the wall of the cabin, verifies in which position the group of drying panels must be arranged in order to be available to carry out the drying of a determined region of the vehicle. For example, in the case in which only the bonnet of the vehicle is to be dried, the operator commands the drying device to translate in the position within a certain range and ensures that only the drying panels of the upper group of panels are switched on (the group of side panels are turned off but are forced to follow the upper group).
  • the scaffolding thus moves within such a range with the upper group panels which are oriented so as to always be orthogonal to the surface of the vehicle within the selected range (this thanks to the storage of the outline line made previously).
  • a first drawback for example, is related to the fact that when the worker inserts the range data into the control station there can be mistakes in reading the values on the metric scale, as well as in "typing" the numeric values.
  • Yet another drawback is related with the fact that the distance of the drying panels during the drying step is fixed, given the knowledge of the outline and its height from the ground, and it includes a safety additional height to avoid accidental bumping into the body of the vehicle, since the detection of the outline is carried out only on a longitudinal line and does not take into account other spatial parameters.
  • a safety height implies the need to have a greater heating than in case of a panel placed closer, with obvious energy waste deriving from it.
  • the main object of the present invention is therefore that of overcoming the aforementioned drawbacks, by providing a positioning system of a drying device in a varnish and/or other material drying plant which is adapted to reduce to a minimum the mistakes due to human actions in determining the space parameters in the cabin used for the drying operations.
  • Another important object of the present invention is to provide a positioning system of a drying device which makes it possible to obtain a reduction in the management costs of the drying plant in which it is inserted.
  • a positioning system of a drying device in a varnish and/or other material drying plant which comprises detection means of at least an outline of an object to be dried and electronic means for controlling the drying operations.
  • the system is characterized in that the electronic control means comprise graphical representation means available to an operator and instructions adapted to generate on said graphical representation means at least a virtual outline corresponding to the profile of the object to be dried detected by the detection means; the instructions establish a correspondence between the graphical representation of the virtual outline and the real position of the object to be dried; the instructions further establish a correlation between the positioning controls of the drying device on the object to be dried and the virtual outline.
  • the varnish and/or other material drying plant is wholly indicated with reference numeral 10 and is housed inside a cabin 11.
  • a plant comprises a support frame of the type having a movable scaffolding comprising vertical uprights 12 adjacent to the side walls of the cabin, which support two parallel beams 13, for guiding the movable scaffolding support along a motion direction which coincides with the direction of development of the cabin, indicated with X.
  • motorised slides 14 that, through arms 15, support the central beam 16 that defines the movable scaffolding.
  • Such a beam 16 extends transversally to the cabin, that is orthogonally with respect to the direction X.
  • Such a transverse direction is indicated with Y.
  • a motorized carriage 17 which slides in the direction Y and that supports a drying device 19 through a frame 18 with an articulated quadrilateral fashion.
  • a frame 18 allows the device 19 to translate vertically (direction Z).
  • the drying device is adapted to translate according to three axes orthogonal to one another, oriented according to main directions of the cabin 11 in which the device operates.
  • the drying device 19, in this embodiment, comprises a single group 20 of side by side drying panels 21a-21b so as to define the drying surface.
  • there are four adjacent drying panels 21 two inner panels 21a and two outer panels 21b that, in their normal configuration, substantially lie on the same plane. In such a normal configuration, the panels offer a generally rectangular drying surface.
  • the outer panels 21 b can rotate at its sides adjacent to the respective inner panels 21 a until they are orthogonal to them, this in order to take on a useful configuration for drying angle regions.
  • the drying device has three degrees of rotational freedom with respect to the movable scaffolding which supports it, thanks to motorized rotation means of the group 20 of drying panels 21 around three rotation axes orthogonal to one another: a turnover axis R parallel to the direction X of development of the cabin 11, a revolution axis B which is orthogonal to the floor of the cabin 11 when the group of panels 20 is oriented with the drying surface parallel to the cabin, as shown in figures 1 and 2 , and a rotation axis G orthogonal to the other two axes R and B, respectively.
  • the drying device 19 allows the group of panels 21 to be placed according to arrangements with any orientation inside the cabin 11 and in particular: 1) a first arrangement in which the group of panels is parallel to the floor of the cabin, with the rectangular development of the group oriented transversally to the development direction X of the cabin itself (see figures 1 and 2 ); 2) a second arrangement in which the group of panels is flipped around the axis R by 90° starting from the first arrangement of figure 1 (see figure 2 ), i.e., with the rectangular development of the group oriented towards the top of the cabin and with the drying surface directed laterally (direction Y); 3) a third arrangement in which, starting from the first arrangement, the group of panels is rotated by 90° around the rotation axis G (see figure 5 ), i.e., with the rectangular development of the group oriented transversally to the development direction X of the cabin 11 and with the drying surface directed parallel to the same direction X; 4) a fourth arrangement in which, starting from the third arrangement, the group of panels is rotated by
  • detection means 22 are provided for detecting the outline of the vehicle (indicated with V), the body of which is to be dried after the varnishing step.
  • such outline detection means 22 comprise a detection sensor 23, for example of the laser type, fixed to the periphery of the inner panels 21 a and oriented orthogonal to them.
  • a detection sensor 23 is connected with electronic control means 24 of the plant 10, like for example an electronic processor comprised in a control station 25 arranged at the side of the cabin and operated by a worker (see figure 1 ).
  • the control station 25 is provided with graphical representation means, i.e., a video interface like a screen 26 which makes it possible to observe and control the drying steps.
  • graphical representation means i.e., a video interface like a screen 26 which makes it possible to observe and control the drying steps.
  • an electronic program is loaded in the management and control processor 24 of the plant which allows a virtual outline P, corresponding to the outline of the vehicle detected with the detection sensor 23, to be generated on the screen 26, as visible in figure 7 .
  • the system learns the position of the vehicle in the cabin 11 in the following way.
  • the drying device is commanded to move from the position "zero" in direction X with the group of panels 21 arranged in the first arrangement, i.e. drying panels parallel to the floor of the cabin with the rectangular development transverse to the cabin.
  • This movement allows the detection sensor 23 to pass above the vehicle, thus detecting the longitudinal outline.
  • Defining the summary outline from the top is carried out by joining the ends of the longitudinal detection profile with two lines orthogonal to the same longitudinal detection and with two lines parallel to the longitudinal detection passing through the right and left outline of the lateral detection.
  • the electronic program translates the acquisition of the outline in a graphical representation, as shown in the central panel C1 of the screen of the video interface of the control station, shown in figure 7 .
  • the operator must order the drying device 19 to position itself on the vehicle V relative to the part of body to be dried.
  • the positioning commands of the drying device are correlated with the virtual outline of the vehicle on the screen so that the operator can give such commands based upon information displayed on the screen.
  • the invention advantageously, provides for the possibility that such a screen 26 is of the "touch-screen" type and that at each area of the screen occupied by a portion of the virtual profile P there is a corresponding indication of space coordinates to the electronic means 24, said coordinates corresponding to an area of the object on which the drying is to be carried out.
  • the program comprises the possibility of also indicating more than one drying area, by pressing a plurality of slots of the grid, thus allowing for a drying sequence to be ordered.
  • the drying device 19 allows the group of drying panels 21 to be oriented in any fashion inside the cabin, said group in practice being able to translate according to the three main directions of the cabin (longitudinal X, transversal Y and vertical Z) and to rotate according to three axes (turnover R, revolution B and rotation G) which are orthogonal to one another and orthogonal to the three main directions X, Y and Z.
  • Such a mobility of the group of panels makes it possible to carry out detections of further outlines in addition to the longitudinal one.
  • the drying device also comprises sensor means for signalling obstacles, such as, in this embodiment, ultrasound signalling sensors 28 mounted on the drying panels 21 and oriented according to the drying direction.
  • sensor means for signalling obstacles such as, in this embodiment, ultrasound signalling sensors 28 mounted on the drying panels 21 and oriented according to the drying direction.
  • Such sensors 28 make it possible to signal the distance of the group of panels from the surface to be dried to the control station and thus make it possible to keep said group as close as possible to such a surface, without the risk of bumping, optimizing in this way the heating.
  • obstacle signalling sensors can be of different types, for example of the laser type, just as the detection sensor of the outline of the vehicle can, for example, also be of the ultrasound type. Furthermore, in other embodiments, the detection sensor and obstacle signalling sensors can be integrated in a single device which carries out both the functions.
  • the positioning system according to the invention can be used with any type of object to be dried and not only with vehicles.
  • it can be used for the drying of body parts which are not fixed to the vehicle, like the doors, mudguards, bonnets etc., which are also hanging or resting on suitable racks inside the drying cabin.
  • the system will provide for moving the device on the rack so as to detect the outlines of the various hanging or support elements.
  • the fact of knowing the entire outline of the vehicle according to different directions makes it possible to select the areas of the vehicle to be dried in a very precise fashion, thus being available to optimize the number of panels switched on for drying, offering benefits in terms of overall energy consumption of the plant.
  • the fact that the panels can remain at an optimal distance from the vehicle means that less thermal energy is necessary for heating compared to the case in which the distance is increased by a safety value to avoid accidents.
