Definitions

  • the subject of the invention is a machine intended for the treatment, and more particularly for the decoration of any profile made of wood, metal, plastic material, etc .; and this is how it aims, for example, at decorating moldings used for the manufacture of picture frames or the like or for decorating furniture of all kinds, the term "decoration" being taken in its most meaningful sense. general to include in particular the painting and varnishing of these moldings.
  • the decoration of wooden moldings it is known to carry out this decoration continuously, by means of a machine in which the molding, animated by a movement of continuous movement by an endless belt , passes through a chamber in which the product to be applied (for example paint or varnish) prevails in the state of mist.
  • the product to be applied is introduced under pressure and in the liquid state into the aforementioned chamber, after having passed through a grid placed in its lower part, and the chamber traversed by the molding is in depression because it is connected to a vacuum pump.
  • the product application chamber On two of its opposite walls, the product application chamber has two openings which face each other and allow the free passage of the molding.
  • the molding receives the product to be applied, which product is deposited on the molding; and it is important to observe that this deposit is made on all sides and therefore on the entire surface of the molding, which results in a relatively large consumption of product, when in reality, certain faces of the molding do not not worth treating. This is so for the faces of the molding which will be invisible when this molding is used.
  • These are in particular the rear face of the molding and possibly grooves which can be arranged in the molding to be used for its fixing or to receive additional elements, which is the case for example when the molding is intended for manufacturing. picture frames.
  • the subject of the invention is a machine which is of the general type mentioned above, but which, thanks to a particular arrangement, allows a saving of treatment product, because thanks to this arrangement, the product is only applied to the subsequently visible faces of the molding.
  • the box delimiting the treatment chamber comprises a guide which extends between the inlet and outlet orifices of the molding in and out of the box, is traversed longitudinally both by the molding and by a current of air from the outside through the orifices and created by the depression prevailing in the box, and successively comprises an upstream zone annularly closed around the molding and in which the mist of treatment product does not prevail, and a downstream zone which only obscures the areas of the molding that should not be subjected to this fog.
  • (1) designates the product application box
  • (2) designates a reservoir located below this box.
  • the treatment liquid (3) In this tank is contained the treatment liquid (3); and a pump (4) is provided to send this liquid through a pipe (5) in the lower part of the box.
  • a vacuum pump (6) driven by a motor (7), is provided to create a vacuum in the tank (2) above the treatment liquid (3).
  • the machine frame Above this pump (6), the machine frame carries an endless belt (8) which is driven in a continuous movement movement and is intended to convey and pass the molding (9) through the treatment box (1) of which two opposite lateral faces are equipped with two doors (10) which are located opposite and have orifices (12) profiled to allow the free passage of the molding respectively at its entry into the box (1) and at its exit from this box.
  • the vacuum produced by the vacuum pump prevails not only in the tank (2), but also in the box or chamber (1) for applying the product, because a connection is made between this tank and this box by means of two chimneys side (13) which opens into the upper part of the box.
  • the liquid treatment product As for the liquid treatment product, it is admitted to the lower part of the box (1 as has been indicated above. This admission is carried out through the pipe (5) which opens into a rigid tube (14) placed longitudinally and having openings (15) through which the treatment product is caused to move upwards, due to the vacuum prevailing in the box (1); and.so that the liquid thus brought into the box becomes a mist , a grid (16) is placed horizontally in the lower part of the box, above the supply tube (14), but below the area to be crossed by the molding (9).
  • the box (1) is provided with a guide, generally designated by (17).
  • This guide is constituted on the one hand, by a base plate (18) which allows its fixing on supports (19) provided in the box (1), and on the other hand, by a profile (21) having two zones (20a, 20b) whose arrangement is different.
  • this profile In the first zone (20a), which is the upstream one, this profile has two lateral wings (21a) connected by a profiled upper wing (21b); and in its downstream area (20b), the profile (21) only includes the two lateral wings (21c).
  • the guide (17) further comprises, internally, an element (22) whose profile is a function of that of the lower or rear face of the molding (9). It is in fact, for this molding, its face or its areas of faces which will not have to be covered with the treatment product.
  • the inner element (22) of the guide (17) then has a U shape whose two legs are of unequal height and which, by its legs, delimits a channel (23) communicating with the outside, outside the box (1).
  • the vacuum prevailing in the box (1) causes a call for air through the orifices (12) of the doors (10), and a current of air is thus established in the guide (17), under all the regions of the underside of the molding (9).
  • the treatment liquid cannot be deposited in these zones and ultimately only deposits on the part of the molding which appears in the downstream zone (20b) of the guide (17), namely above the two lateral wings (21 a) and downstream with respect to the upper wing (21 b) of the guide (17).
  • the treatment product is applied to the molding only in a reduced area of the guide (17). This is its second zone (20b), that is to say that located downstream of its upper wing (21b); and it is in this downstream area that only the areas of the molding which will be visible during the use of this molding are finally covered with the treatment product.
