Definitions

  • the present invention relates to a device for applying a viscous liquid product, and in particular a sticky mixture on one face of a moving support, device which comprises an applicator shoe having at one end, a nose pierced with at at least one orifice for dispensing the application product, which normally comes to be placed in the immediate vicinity of said face of the moving support and which communicates with a supply product application duct equipped with a shutter valve.
  • the present invention also relates to an installation for gluing pieces of wood equipped with such an application device.
  • gluing operations are often carried out on pieces of wood.
  • various application devices are currently available, such as metering rollers which apply a film of glue to the pieces of wood or perforated ramps which deposit threads of glue on moving parts under those -this.
  • US Patent No. 2,726,632 describes an application device of the perforated ramp type, more specifically intended for coating porous building elements, such as concrete blocks, bricks, tiles, etc.
  • the perforated ramp is provided at the end of an applicator shoe kept fixed above the elements to be coated scrolling under it. This document served as the basis for the preparation of the preamble of claim 1.
  • Such a device has the drawback of being rigid in use and of a very limited field of application. In particular, it does not make it possible to coat supports in any position and is not suitable for all the widths and thicknesses of these supports. It also does not have an adjustable automatic supply of coating product, which makes them unprofitable and leads, in the case of continuous gluing of pieces of wood, to losses of gluing product.
  • the present invention proposes to remedy these drawbacks and to do this it relates to an application device of the type specified above, which is characterized in that the applicator shoe is pivotally mounted around a fixed axis substantially perpendicular to the direction of movement of the support and comprises means for positioning the nose of the shoe capable of maintaining the latter in a variable working position, these positioning means comprising at least elastic member which biases the shoe in its direction of pivoting towards the support .
  • this application device can be adapted to all the thicknesses of the support to be coated because its shoe is pivoting.
  • said positioning means comprise a tail fixed to the shoe opposite the nose relative to the pivot axis, the elastic member being constituted by a spring which exerts its action on this tail to bring the nose of the shoe in the trajectory of the support, so that, as soon as the latter comes into contact with the nose, the shoe passes automatically, against the action of the spring from a lowered position of rest to a raised position in which his nose is kept pressed against the support.
  • This arrangement allows the application device to work in any position.
  • the displacement of the tail of the shoe in said pivoting direction is limited by an adjustment screw forming a stop.
  • said positioning means comprise an arm secured at one end to the shoe, and receiving at its other end a screw which rests freely on a fixed support plate, the elastic member being constituted by a spring collides the arm towards this support plate. By acting on this screw, the arm can be moved relative to the support plate and thus adjust the height of the nose of the shoe relative to the face to be coated.
  • the shoe is mounted oscillating around a pivot perpendicular to the pivot axis and rotatably mounted around the latter, guide means integral with the shoe being provided to keep the latter centered on the axis of the face to be coated with the support, and in a preferred embodiment, these guide means comprise a pad capable of being applied to an edge of the support and a leaf spring intended to come to bear elastically on the other song of the support.
  • the leaf spring is mounted, by means of a screw-nut assembly, on a slide perpendicular to the direction of movement of the support, which makes it possible to adjust its position according to the width of the support.
  • the application device comprises a control member of the shutter valve ensuring the supply of application product to the shoe.
  • this control member In a first embodiment of the valve control member designed to operate in combination with the first embodiment of the means for positioning the nose of the applicator shoe, this control member consists of a reverse microswitch disposed in the path of movement of the tail so as to pass into a position controlling the opening of the valve when the shoe is raised in its working position. The supply of hoof product is thus de triggered by the hoof itself when its nose is raised by the moving support.
  • the control member is constituted by a micro-switch placed on the path of the support to be actuated by one or the other of the ends of the latter during its movement or by a photoelectric cell the light beam cuts the path of the support.
  • the microswitch is slidably mounted on a graduated rule parallel to the direction of movement of the support. It is thus possible to adjust the position of the micro-switch upstream of the nose of the hoof as a function of the speed of advance of the support, to compensate for the response time of the hoof feeding system and allow precise application of the product from the front end of the support.
  • the photoelectric cell is associated with an adjustable timer relay.
  • the nose of the shoe consists of a hollow ramp removably mounted on the free end of the shoe and pierced with the orifice (s). It is therefore possible to mount on the shoe ramps of any length adapted to the widths of the supports to be coated, and in particular very long ramps for gluing the plywood panels. Thanks to this arrangement, it is also possible to adjust the orientation of the orifices of the nose of the shoe as desired.
  • This installation is specially designed to ensure the continuous production of a sticky mixture from a resin and a hardener, and its application on wooden slats.
  • it comprises two reservoirs 1 and 2 respectively containing resin and hardener, and each associated with a pump 3 or 4.
  • the pumps 3 and 4 transfer, through conduits 5 and 6, two separate streams of resin and hardener in a two-piston volumetric doser 7.
  • a filter 8 is also provided on the resin duct 5.
  • the sticky mixture formed at the outlet of the head 9 is deposited in nets, by means of an application device 12, on displaced wooden slats L in succession in front of the latter by rollers 13.
  • a flexible duct 14 on which a valve 15 is mounted connects the outlet of the mixing head 9 to the application device 12.
  • a water supply 16 associated with a valve 17 makes it possible to clean the mixing head 9 during the per iodine not using it.
  • the reference 18 designates a pneumatic cabinet which supplies compressed air to the pumps 3 and 4, the metering device 7 and the valves 10, 11, 15 and 17.
  • the application device 12 which is more precisely the subject of the present invention, is shown in a first embodiment in FIG. 1.
  • this device comprises an applicator shoe 19 mounted pivotally around a fixed axis 20 parallel to the face F to be bonded to the slat L and perpendicular to the direction of movement of the latter.
  • the axis 20 is carried by the frame, not shown, of the installation.
  • the shoe 19 is further inclined in the direction of movement B of the slat L and has at its free end a nose 21 shaped as a bevel and parallel to the axis 20.
  • FIG. 1 As can be seen better in FIG.
  • the nose 21 has a width which corresponds substantially to that of the slat L and is pierced with orifices 22 which communicate, through internal channels 23 in the shoe, with the supply duct 14, these orifices being arranged in an alignment perpendicular to the direction of displacement of the batten L, to deposit on it sticky mixing threads parallel to the edges of the slat.
  • OldlA 10 shoe 19 has a tail 24 which extends behind the axis 20 and radially with respect thereto.
  • the tail 24 is biased by a spring 25 in a direction which makes the shoe 19 pivot towards the plane of movement of the slat L so that its nose 21 is placed in the path of the latter.
  • the shoe 19 automatically passes, against the action of the spring 25, from a position lowered from rest (not shown) to a raised working position in which the nose 21 is kept applied against the slat L.
  • the rest position of the shoe can be adjusted by a screw 26 constituting a stop for the tail 24.
  • the shoe 19 is supplied with an adhesive mixture via a valve 15.
  • This valve 15 as well as valves 10 and 11 and the pumps 3 and 4 are made active inactive by a control member 27 arranged in the electrical circuit of control of the cabinet 18, and constituted here by a micro-contactor 27, arranged in the path of the tail 24 of the shoe to be moved by the latter during the pivoting of the shoe.
  • the microswitch is raised by the tail 24 and cuts the power to the shoe.
  • the shoe is raised by the batten, it is lowered, as shown in FIG. 1 and triggers the supply of sticky mixture of the shoe 19. Once the batten has completely passed the nose of the shoe, the latter it returns to its rest position, which stops its supply of sticky mixture.
  • the shoe 19 can be mounted around a horizontal axis (see FIG. 2) for the gluing of slats moving flat, with a view in particular to the manufacture of glued laminated beams.
  • the shoe 19 can be pivotally mounted around a vertical axis (see FIG. 3), in order to equip paneling and lathing machines in which the slats are rolled up while standing on one of their edges.
  • Figures 4 and 5 show a second embodiment of the application device according to the invention, in which the shoe 19 is mounted oscillating around a pivot 28 perpendicular to the axis 20 and carried by a sleeve 29 surrounding with a slight play the latter. Furthermore, the shoe 19 carries on one side, a shoe 30 disposed along the path of the slat L, so as to come to apply, during the displacement of the latter, on one of its edges.
  • a leaf spring 31, integral with the shoe faces the shoe 30 and extends slightly in the path of the slat L so as to bear elastically on the other edge of the latter.
  • the moving batten is clamped between the shoe 30 and the leaf spring 31 so that the shoe 19 is kept perfectly centered on the axis of its face to be bonded even in the event of a lack of straightness of the edges.
  • the leaf spring 31 is mounted, by means of a screw-nut assembly 32, on a slide 33 secured to the shoe 19, which extends perpendicular to the direction of movement of the slat. It is thus possible to adjust the position of the blade 31 as a function of the width of the strip to be glued.
  • the shoe 19 includes an arm 34 which maintains the nose 21 at an adjustable height of the slat L.
  • the arm 34 is connected at one end to the sleeve 29 and receives at its other end a screw 35 which rests on a fixed support plate 36 forming part of the frame of the installation.
  • a spring 37 working in compression biases the arm 34 towards this support plate 36. It will easily be understood that by acting on the screw 35, it is possible to raise or lower the nose of the shoe to adjust its height relative to the strip to be glued.
  • FIG. 4 also shows a preferred embodiment of the nose 21 in the case of the shoe of FIGS. 4 and 5.
  • This nose is constituted by a hollow cylindrical ramp 38, removably mounted, by screws 38a, inside a clevis 39 secured to the free end of the shoe 19.
  • the orifices 22 are produced, in this case, through the wall of the ramp, and the supply duct 14 communicates with the interior of the latter. It will be understood that one can, by this means, easily adapt to the shoe ramps of all lengths corresponding to the width of the support to be glued, wooden slat, plywood panel or others.
  • Another advantage of this embodiment of the nose lies in the fact that the orientation of the orifices 22 can be modified as desired. They can thus be directed perpendicular to the support L, as shown in FIG. 4, or obliquely in the direction of movement of the support, as shown in FIG. 6.
  • a micro-switch 40 placed along the path of the slat L so as to be actuated by it during its passage.
  • the microswitch 40 is positioned upstream of the nose 19 of the shoe 21 and at a distance such that the time taken by the front end E of the batten to travel over this distance is equal to the response time of the supply system, that is to say the time taken by the sticky mixture, to reach the orifices 22 from the instant of actuation of the micro-switch.
  • This arrangement is essential for precisely gluing wooden slats driven at high speed over their entire length. It goes from the position of the microswitch 40 must be modified as a function of the advancement speed of the slat and, for this reason, the microswitch 40 is slidably mounted on a graduated rule 41 parallel to the direction of movement of the slats .
  • a photoelectric cell 42 whose light ray intersects the path of the slat L can play the same role as the micro-switch.
  • the cell 42 is arranged in a fixed place and the change in the speed of advancement of the slats is compensated by the action of an adjustable timer relay 43 mounted in series with the cell 42 in the electrical control circuit of the cabinet 18.
  • the microswitch 40 or the photoelectric cell 42 can obviously equip the shoe of FIGS. 1 and 2 to replace the microswitch 27.
  • FIG. 8 represents another means of compensating for the response time of the supply system, adaptable to the shoe of FIGS. 1 and 2.
  • These means comprise a buffer tank 44 in which a piston 45 is slidably mounted which divides the buffer tank into two chambers 46 and 47.
  • the chamber 46 is connected to the supply duct 14 of the shoe 19, and communicates with the orifices 22 thereof via a solenoid valve 48 controlled by the microswitch 27.
  • the other chamber 47 is permanently supplied with compressed air through a conduit 49.
  • An adjustable stop 50 is further provided for limit the return stroke of the piston 45 and fix the volume of the chamber 46. This stop is in fact constituted by a pulse contact mounted on the electrical control circuit of the cabinet 18.
  • the microswitch 27 is opened while keeping the solenoid valve 48 closed.
  • the feeding of the shoe is then manually triggered, which has the effect of filling the chamber 46 of the tank with a quantity R of sticky mixture determined by the position of the contact 50, adjusted as a function of the speed of advance and the width of the slats.
  • the piston 45 moved by the sticky mixture, touches the contact 50, the feed to the shoe is stopped.
  • the solenoid valve opens and, during the response time of the supply system, the piston 45 pushes the quantity R of sticky mixture through the orifices 22 while awaiting the normal arrival of the sticky mixture through the conduit 14.
  • the microswitch opens and the solenoid valve 48 closes.
  • the chamber 46 of the buffer tank then fills with the quantity R of sticky mixture for the next supply cycle.
  • this buffer tank can equip a shoe of the second embodiment associated with a micro-switch or a photoelectric cell placed fixed at the nose of the shoe.
  • the application device allows precision gluing, automatic and continuously, of pieces of wood moving in succession in front of it, without loss of sticky mixture. It can be adapted to all the widths and thicknesses of the pieces of wood and allows gluing in all positions, and in particular horizontal and vertical, of these.
  • the device according to the invention can of course be used for the application of any viscous liquid product on any type of rigid support.
