Definitions

  • the present invention relates to a device for treating the surface of an object with solid particles.
  • the treatment of the surface of an object with more or less abrasive solid particles has been known for a long time, either for pickling or for improving the surface condition, for example obtaining a matt or shiny appearance. .
  • FR-A-1 057 952 describes a device comprising containers with a vertical axis, into which the objects carried are lowered by a vertical sliding rod placed above them.
  • JP-A-5 882 669 describes an apparatus of the same kind, but where the tank has an axis inclined by 30 to 45% on the vertical, its upper end being open and provided with a flange for retaining the particles, and where l he object is maintained, thanks to a vertical sliding rod, in the lowest part of the volume of the container.
  • Such devices cannot be transposed for the treatment of fragile objects, such as furniture or parts of furniture, because problems arise during the penetration of the object into the mass of solid particles; unless you proceed very slowly, it takes considerable force to push the object in, even if the container is rotating, and the object may be damaged.
  • the current technique consists in pouring the particles out of the container during the time of the introduction of the object, then in gradually re-introducing these particles into the container, preferably during the rotation of the latter. These operations are slow and costly.
  • the object of the present invention is to provide a device of the type indicated above in which the operations for introducing and extracting the object to be treated are simple and rapid, the device however being as compact as possible.
  • a tank 1, of cylindrical shape, is carried by a frame 2, so as to be able to rotate around its axis, the latter being inclined at approximately 30 ° relative to the horizontal.
  • the chassis carries two series of rollers 3, 3a parallel to the axis of the tank, and arranged on either side of the vertical plane of symmetry thereof. These rollers support the tank, while other rollers 4, of axis perpendicular to that of the tank, and arranged below the latter, prevent it from descending along the chassis under the effect of its weight.
  • a motor 5 rotates some of the rollers 3, 3a and therefore also rotates the tank itself, around its axis.
  • the bottom of the tank is crossed axially by a tubular guide 6, which serves as a guide for a cylindrical column 7 which is part of the seat support and which can slide inside the guide 6.
  • the column 7 advances beyond the guide 6 and carries a device for holding a seat 8.
  • This device comprises a fixed annular plate 9, integral with the column 7, and a movable assembly 10 driven by cylinder and capable of clamping the cross members of the seat between itself and the plate 9.
  • connection between the jack 11 and the chassis 2 is ensured by an articulation of the conventional type.
  • the other end of the jack is also connected by a conventional type articulation to a carriage 16 mounted on slides fixed to the chassis 2, supporting an eccentric device connected to the column 7, better visible in FIGS. 3 and 4.
  • This device comprises a yoke 12 integral with the carriage 16 and a link 17 articulated on the column 7.
  • An axis 14 crosses both the yoke 12 and the link 17. It is rotated by a motor 15, by means of a coupling 13. This shaft has at the link 17 an eccentric part so that when the engine is running, it gives an oscillating movement to the column 7 via the link 17, at a frequency which depends on the speed of rotation of the engine. The oscillations in the direction of the axis of column 7 are transmitted to object 8.
  • the vibration movement can be generated directly by the jack 11 by imparting periodic pulses to the control fluid thereof.
  • the tank At its opposite end, that is to say at its upper end, the tank is only partially closed, it has a central circular opening 18, of sufficient size to allow the passage of one of the pieces of furniture desired. treat.
  • This central opening is surrounded by a collar 19, intended to retain the glass balls 20 which are contained in the tank and which are intended for the desired treatment.
  • a suction hood 21 serves to collect the dust escaping through the opening 18. This hood is fixed, that is to say that it is not driven in rotation by the tank 1.
  • Figure 1 shows the loading position: in this position, the cylinder 11 is in the extended position, the column 7 is advanced along the axis of the tank so that the device for fixing a piece of furniture 8 located near the opening 18.
  • the device for fixing a piece of furniture 8 located near the opening 18. it is easy for an operator to set up a piece of furniture between the plate 9 and the movable assembly 10, which is then moved back to allow the furniture to be put in place. During this operation, the tank is stopped.
  • Figure 2 shows the installation in working situation, the cylinder 11 is then in the retracted position, and the seat then occupies substantially the center of the tank. It is noted that, in the loading position, the mass of balls 20 is always in place therein. The passage from the loading position to the working position is however done without difficulty provided that the furniture is gradually moved towards the interior of the tank using the jack 11, while the tank, and consequently the balls 20 , are in motion. The latter are driven by the rotating tank, they fall in rain therein, in particular on the object to be treated. The surface treatment work therefore begins even before the end of the movement to the working position. In Figure 2, there is shown by a horizontal line the upper level of the mass of balls 20. It should be noted that, during work, there is no stable position of the free surface of the mass of balls , these acting on all parts of the furniture contrary to what one might think by observing Figure 2.
  • the inclination of the axis of the tank is not critical, however if this inclination is too small, it will be necessary to give the tank a greater length to prevent the balls from escaping by passing over the flange 19 If, on the contrary, the axis of the tank is given a too strong inclination, the parts of the piece of furniture which will be located near the bottom risk of having a milking too energetic compared to the parts of the furniture on the opposite side. Tests have shown that an inclination of around 30 °, for furniture such as chairs, armchairs, stools or parts of sofas is suitable. With regard to the vibration in the direction parallel to the axis, it has been found that a frequency of the order of 15 Hz with an amplitude of approximately 5 mm is suitable.
  • the tank turns on itself with a rotation speed of the order of 15 revolutions / minute with reversal of the direction of rotation after an interval of one to two and a half minutes. It has been observed that this speed, which ensures that the balls fall well in the rain on the object to be treated, is the most suitable for the size of the tank and the nature of the particles.
  • the adaptation of the conditions to each case is within the reach of the skilled person.
  • a too low speed displaces the grains insufficiently while a too high speed the plates against the walls by the effect of centrifugal force. It has been found that the device according to the invention provides good quality results, that it is easy to charge with a minimum loss of time, and a minimum of fatigue.
