Definitions

  • the present invention relates to a glue distributing apparatus, in particular an apparatus for distributing glue in a woodworking machine, such as for example an edgebanding machine or a squaring edgebanding machine.
  • Such machines which typically perform edgebanding operations on panels, tables, flat elements of wood or similar material, comprise glue distributing apparatuses or gluing units that deposit or spread a layer of adhesive glue on belts, strips, beads to be applied to edges of panels, or directly to the edges of said panels.
  • the adhesive used is generally a hot-melt glue that has to be appropriately heated before being applied "hot” to surfaces to be joined.
  • the glue is applied by means of a suitable rotating gluing roller, that has a knurled or rough external surface, which retains and conveys the glue, supplied by a tank or pot.
  • the latter is made of a non-adhering material and is provided with heating elements, such as electric resistances, for uniformly heating and keeping fluid the glue.
  • the glue tank is positioned below a work area and suitable supplying means, for example screw conveyor, transfers the glue from said lower tank to the gluing roller.
  • glue distributing apparatuses are known that are provided with glue tanks positioned next to the gluing roller and which extend upwards. In this way the heat generated by the tank resistances can be dissipated to the external environment and does not affect, unless marginally, the work area and in particular the roller and the corresponding movement members.
  • the tank has a lower portion or chamber provided with an opening through which the glue flows by force of gravity to the gluing roller. The latter partially shuts said opening and, by rotating, transfers and spread the glue on the surfaces of the elements to be joined.
  • glue adjusting means comprising fixed doctor blades for adjusting the quantity of glue to be spread onto the knurled surface of the gluing roller.
  • these apparatuses can comprise a first doctor blade, called dosing doctor blade, for depositing or spreading an uniform layer of glue of a fixed thickness on the gluing roller, and a second doctor blade, called return or recovery doctor blade, which recovers the exceeding glue on the roller that has not been transferred to the surface to be glued.
  • the return doctor blade moreover keeps any foreign bodies outside the chamber.
  • doctor blades are arranged parallel to one another at a preset distance, opposite the opening of the lower chamber of the tank in such a way as to form a cavity in which the glue gathers that is taken from the roller.
  • Each doctor blade comprises an elongated flat element, provided with an edge abutting on the gluing roller along a generatrix thereof, operating substantially as a "spatula” to spread a uniform layer of glue on said roller.
  • each doctor blade may consist of a cylindrical pivot, arranged parallel to the gluing roller and provided with a longitudinal plane that constitutes a flat surface that conveys and spreads the glue on the roller.
  • the presence of two distinct doctor blades requires laborious and complex management of the apparatus since adjusting operations for correctly positioning and orienting doctor blades with respect to the roller must be repeated separately for each doctor blade and need skilled operators and also long stops of the machine.
  • the gluing roller can, in fact, rotate both in a clockwise and in an anticlockwise direction, according to whether, for example, strips or belts have to be glued, in the case of so-called "softforming", or panels to be edgebanded have to be glued, in the case of so-called "straight" forming.
  • An object of the invention is to improve known glue distributing apparatuses, in particular for woodworking machines for machining elements of wood or similar materials. Another object is to obtain a glue distributing apparatus, which allows adjusting and controlling in a simple, fast and effective manner the glue to be spread on surfaces to be glued, regardless of a rotation direction of gluing roller.
  • a glue distributing apparatus comprising roller means for applying a glue to an element to be glued, tank means containing said glue and provided with an opening for conveying said glue to said roller means, and adjusting means interposed between said roller means and said opening for adjusting a quantity of glue transferred to/from said roller means, characterised in that said adjusting means comprises movable and interconnected doctor blade means.
  • a glue distributing apparatus comprising roller means 2, tank means 3 and adjusting means 4.
  • Roller means 2 comprises a rotating roller, of known type, having a rough or knurled external surface 2a for removing, conveying and applying a preset layer of glue to an element 50 to be glued.
  • the roller 2 is rotated by suitable actuating means, of known type and not shown in the Figures, and it can be rotate both clockwise and anticlockwise, depending on elements 50 to be glued.
  • the roller 2 rotates clockwise to glue strips or belts in the so-called “softforming” process, whilst it rotates anticlockwise to glue edges of panels or tables to be edgebanded, in the so-called “straight” process.
  • Tank means 3 which contains the glue and is placed next to the roller means 2, extends upwards and is provided with an opening 3a for conveying said glue to the roller means 2.
  • the tank means 3 is further provided with a plurality of electric heating elements 23 that are able to heat and melt uniformly the glue and to maintain fluid the latter.
  • the opening 3a of tank means 3 has a height that is almost the same as that of a portion of the roller 2 configured for receiving the glue.
  • Adjusting means 4 is interposed between the roller means 2 and the opening 3a for regulating a quantity of glue transferred to the roller 2 for a subsequent application on an element 50 to be glued. Adjusting means 4 is further configured so as to recover from the roller 2 the exceeding glue, which has not been spread on element 50.
  • Adjusting means 4 comprises doctor blade means 5, 6 provided with respective cavity means 5a, 6a.
  • Doctor blade means comprise a first doctor blade 5 and a second doctor blade 6.
  • Each doctor blade 5, 6 is an element with a longitudinally elongated shape, for example a pin with an approximately cylindrical section, on which a respective cavity 5a, 6a is made, consisting of an open hollow space that extends longitudinally for about the entire length of the element.
  • the cavity 5a, 6a is for example a straight groove with a U-shaped cross section having a concave bottom wall.
  • the two doctor blade 5, 6 are arranged parallel each other and spaced apart from one another in such a way that the respective cavities 5a, 6a are almost face one another to form a volume or space 7 that is shaped for containing the glue. It has been find out that such cavities 5a, 6a reduce and limit considerably the formation of turbulences and vortices in the liquid glue during rotation of roller 2. This enables an almost uniform and homogenous distribution of the glue on the whole length of roller 2 to be obtained, regardless of a rotation speed of roller 2.
  • Each doctor blade 5, 6 comprises an abutting portion 5b, 6b, configured so as to contact the roller 2, and a sealing portion 5c, 6c suitable for abutting on a respective seat 3b, 3c of tank means 3.
  • the abutting portion 5b, 6b is, for example, an edge made on an external surface of the doctor blade, whilst the sealing portion 5c, 6c is a portion of said external surface, having a concave shape, complementary to a shape of seat 3b, 3c, for example a portion of cylindrical surface.
  • Each doctor blade 5, 6 is rotatably mounted around a respective rotation axis 5d, 6d, so as to be movable between a first working position A and a respective second working position B.
  • the rotation axes 5d, 6d are parallel to one another and also parallel to a rotation shaft 8 of the roller 2.
  • the abutting portion 5b, 6b of the doctor blade 5, 6 substantially abuts on the external surface 2a of the roller 2 in such a way as to adjust the passage of glue to be deposited onto the roller and to uniformly extend said glue onto said outside surface 2a.
  • the abutting portion 5b, 6b of doctor blade 5, 6 is spaced from a respective external surface 2a of roller 2 to enable the exceeding glue on the roller 2 to be recovered and at the same time to prevent possible foreign bodies entering the volume 7.
  • Driving means of known type and not shown in the Figures, is provided for rotating the doctor blades 5, 6 between the two working positions.
  • the doctor blades 5, 6 can be mounted so as to independently rotate, driven separately by respective driving means.
  • doctor blades 5, 6 can be mounted linked together and connected by suitable interconnecting means, in such a way as to rotate together.
  • Said interconnecting means can be of mechanical type, for example pulley or gear mechanisms, or of electronic type, for example electronic control means of actuating means.
  • a rotation of a doctor blade is matched by a same rotation of the other doctor blade. More specifically and with reference to Figures 2 and 3 , when for example the first doctor blade 5 is in the respective first working position A, the second doctor blade 6 is in the respective second working position B.
  • the apparatus 1 is in a first operating configuration P in which the roller 2 rotates in an anticlockwise direction, for example to apply glue to an edge of a panel 50.
  • the apparatus 1 is in a second operating configuration Q wherein the roller 2 rotates in a clockwise direction, for example to apply glue to a strip or belt 50.
  • the doctor blade 5, 6 can also be made as a single body. In this case, the respective rotation axes 5d, 6d are coincident.
  • FIGS 4 to 7 show a version of the apparatus 1 which comprises shutting means 10, that is movable and interposed between the roller 2 and the opening 3a of the tank means 3 for closing and/or opening said opening 3a.
  • shutting means 10 can be inserted between the adjusting means 4 and said opening 3a.
  • Shutting means 10 is movable between a closed position C, in which it shuts said opening 3a to prevent the glue passing from the tank means 3 to the roller 2 ( Figure 7 ), and a complete open position D, in which it opens said opening 3a and enables the glue to pass through ( Figures 5, 6 ).
  • the shutting means 10 can adjust a glue flow to the roller 2, partially closing the opening 3a.
  • Shutting means 10 comprises an elongated element, substantially cylindrical, rotatably mounted on a rotating pin 11.
  • Shutting means 10 further has a passage 12 comprising a longitudinal through opening that enables the glue to transit and which has a length that is almost equal to a height of the opening 3a.
  • Shutting means 10 is contained in a suitable respective seat 3d made in the tank means 3, inside which it can rotate.
  • the adjusting means 4 comprises a couple of doctor blades 15, 16 made of a single body and rotatable around respective rotation axes 15d, 16d that in this case coincide.
  • the adjusting means 4 comprises an elongated tubular element 19 that is substantially cylindrical with open section, provided with two facing and opposite portions 15, 16 acting as doctor blades.
  • Each doctor blade 15, 16 has a respective abutting portion 15b, 16b, configured so as to abut on the external surface 2a of the roller 2, and a respective sealing portion 15c, 16c configured so as to abut on said respective seat 3d of tank means 3.
  • the tubular body 19 of the adjusting means 4 has an internal cylindrical cavity 17 into which the shutting means 10 is inserted coaxially.
  • Glue coming from the tank means 3 can pass through the slot 18 to reach roller means 2.
  • This version of the distributing apparatus 1 thus comprises adjusting means 4 and shutting means 10 in a very compact structure.
  • Adjusting means 4 that comprises two doctor blades 15, 16, that are integral and movable at the same time, allows adjusting and controlling in a simple, rapid and effective manner a distribution of the glue on surfaces to be glue, regardless of a rotation direction of the roller 2.
  • shutting means 10 can close hermetically the opening 3a, thus preventing glue from reaching the roller 2 and leaking through passages and openings of the external surface 2a of said roller during stop phases of the apparatus.
  • Shutting means 10 comprises a couple of recesses 13, 14, made on an internal wall of the passage 12 for an entire extent of the latter.
  • Recesses 13, 14 are substantially the same and symmetrically arranged with respect to a longitudinal plane of symmetry S of shutting means 4.
  • said recesses 13, 14, which have an almost U-shaped section, are arranged so as to form a respective cavity 20 converging on roller means 2.
  • respective cavities can be provided on the walls of the tubular body 19 of adjusting means 4 at the doctor blades 15, 16.
