Definitions

  • the invention relates to a method for the mutual gluing of panels, in particular veneers made of wood, as characterized in the preamble of claim 1, and a device required to carry out the method.
  • the blunt gluing of veneer pieces with their long sides into strips and subsequent cutting into custom-made panels of the same size is used to manufacture plywood or other large-area panels, for example.
  • a method for this in which the veneer pieces are first machined either in a continuous process or in batches on their long sides and provided with a cold glue. Then the pre-treated ones Pieces of veneer placed in a veneer splicing machine one after the other transversely to the direction of transport, where they were successively joined and glued together using pressure and heat.
  • This method only achieves good results if it is ensured that the long sides are not soiled and damaged between the application of the glue and the subsequent assembly.
  • two expensive and space-consuming machines are required for this, which makes the practical application economically unprofitable.
  • the applied adhesive is pressed further into the interspace while pressing the two plates against a flat surface, and excess residues are pressed into the surface, at the same time the adhesive hardens.
  • the device according to the invention enables the individual plates to be assembled quickly one after the other, which enables industrial production with this method.

  • Fig. 9 is a top view of Fig. 8 with a schematic representation of the glue injectors and the attachment of the side adhesive strips.
  • the panels or the veneer pieces are transported in the direction X by means of a conveyor belt 22 and first meet a device for gluing, generally designated 100. After gluing, the panels arrive at a device 110 for applying side adhesive strips to the glued panels, as is described in more detail with reference to FIG. 8. Thereafter, the plates glued into a belt arrive at a cutting machine 60 which is controlled by a scanning element 63 arranged on a conveyor belt 61 in such a way that the plates are all cut to the same size. The conveyor belt 61 transports the cut plates 62 to a stack 62 '.
  • the gluing of the panel sides for example the rear edge 9 'of the front panel 9 with the front edge 18' of the rear panel 18, is realized with the device 100 according to FIG. 1 or enlarged according to FIG. 2.
  • a plate 9, the leading edge of which has already been glued is advanced in the direction X until the photocell 1, after passing through the trailing edge 9 ', stops the conveyor belt 22, which rotates on rollers 10.
  • cell 2 controls a stop 12 which emerges from a support surface 11, the stop plane being in line with a transverse line 12 'which later becomes the adhesive line 12'.
  • a return movement of the plate 9 against the direction X is initiated by a roller or rollers 8, which is pressed on by a pressure device 7, and by reversing the direction of travel of the conveyor belt 22.
  • This back movement of the plate 9 takes place until the edge 9 'is leaned against the stop 12 with this edge 9' being equated along the adhesive line 12 '.
  • a pressing device 6 is lowered onto the plate 9 by means of a drive 23 in order to hold the plate 9 securely in this position.
  • the stop 12 is brought back into the lower starting position, the rollers 8 are lifted off the plate 9 and a feed device transports the plate 18 to the edge 9 'of the plate 9 along the glue line 12' until its edge 13 '.
  • the system for advancing the plate 18 consists of the conveyor belt 22 and a further conveyor belt 21 with deflection rollers 17 and 19, of which the former is equipped with a pressing device 16. After mutual contact of the edges 18 'and 9', the conveyor belts 21 and 22 are stopped by a signal from the photocell 1 and the rollers 17 are raised by the pressing device 16.
  • the gluing process begins by means of injection of the glue along the gluing line 12 ', which corresponds to the line of contact of the edges 9' and 18 'of the two plates 9 and 18.
  • the gluing process by means of the gluing device 3 6 schematically illustrates where a container 13 filled with an adhesive can be seen, which has a temperature required for processing the adhesive.
  • the container 13 is fastened to a pivotable carrier 20, by means of which it is brought into a vertical working position, equal to the transverse line 12 '. In this position, a mechanical press 4 acts on the container 13 in order to press it against the two plates 18 and 9 and these in turn against the support surface 11.
  • the container 13 has a cavity 13 'in which the liquid adhesive 32 is contained, for example an adhesive with two components, which can be filled in through an opening which can be closed with a lid 26.
  • the walls of the container 13 are with insulating parts 35 ', Heating elements 25 and a temperature controller 33 to keep the adhesive 32 in the best temperature conditions.
  • the carrier 20 of the container 13 is advantageously formed by a square tube through which water 29 can be passed for cooling.
  • the press 4 acts on a pressure element 27 which is expediently attached to the container as an extension of the adhesive line 12 '.
  • the upper part of the container 13 is connected by a pipe 28 to a three-way valve 14, which in turn is connected to a pipe 30 for the supply of compressed air and with a connection 31 for the discharge into the outside atmosphere.
  • the space 13 ' can be selectively connected to the pressure source or to the outside atmosphere.
  • the lower part of the container 13 is aligned with the axis of the pressure element 27 and the line 12 '
  • Series of nozzles 49 which consist of bores 36, inlet openings 37, and circular injection zones 34 arranged in a rotating element 35, the inlet openings 37 for the injection of the adhesive being able to be closed by pivoting the rotating element 35.
  • Each container 13 has a plurality of nozzles 49 or circular injection zones 34, as can be seen, for example, from FIG. 9, and from which it can also be seen that a plurality of containers 13 are provided in the spaces between the feed device 16, 17.
  • a lever 38 is able to turn the rotating element 35 by means of a controllable drive 39 to stop the glue from flowing out. For this reason, the rotary element 35 and the three-way valve 14 are actuated practically simultaneously in order to carry out the injection of the adhesive consistently in multiple points along the adhesive line 12 ′. This injection takes place under a pressure in order to guarantee that the glue reaches the vicinity of the support surface 11 through the ajar sides of the plates.
  • the rotary element 35 is closed and the three-way valve 14 is actuated so that the space 13 'is connected to the outside atmosphere, in this way the injection is interrupted and then the container 13 is lifted, as can be seen from FIG. 7 .
  • a pressing element 5, the so-called “hammer” is lifted over the adhesive line 12 ', which is moved by a group of piston cylinders 24 from. a rest position corresponding to FIG. 6 can be moved into a working position corresponding to FIG. 7.
  • the pressing element 5, which is advantageously provided with cooling, is pressed by the press 4 onto the adhesive line 12 'and allows the possible projections of the adhesive to be completely leveled and the adhesive to be bound by cooling.
  • the rest position of the pressing element 5 is seen behind in the direction of flow and that of the gluing device 3 is arranged in front of the adhesive line 12 '. This ensures a quick change from the working position of the glue device 3 to its rest position and at the same time from the rest position of the pressing element 5 into its working position.
  • the gluing device 3 is advantageously fastened to swivel arms, which are shown in simplified form in FIG. 2 only as dash-dotted lines 53, which are e.g. of an air or hydraulic cylinder are pivotable.
  • the described device is able to carry out a sequence of the above-mentioned gluing operations at a rate of 18 to 20 gluing operations per minute, while the effective time of the actual gluing is about 2 seconds.
  • a device 110 for the application of adhesive strips 52 can be installed after the device 100 for gluing, which device prevents breakage of any cracks on the plates during further transport, as is also the case 8 and 9 show.
  • the device 110 essentially consists of an adhesive strip roll 50 mounted on a bolt 51, which is rolled up in such a way that it continuously comes into contact with a type of sponge 42 via a roller 43, which in turn hangs in a bowl 41 filled with water, for example, and the Adhesive on the strip 52 activated.
  • the strip is then attached using rollers 47, which may be heated and driven by a drive shaft 46 and chain 48.
  • the entire device is adjustable in height with the aid of a piston cylinder group 44 displaceable in the transverse direction by means of a carrier 45.
  • the application of adhesive strips 52 allows the wood panels to be further processed without the risk of breaks and cracks.
