Definitions

  • the invention relates to a method and an apparatus for joining strip frames for the production of sandwich panels for the furniture industry or as components.
  • Sandwich panels are known from the prior art. They consist of a strip frame, which forms a free space in which honeycomb inserts, for example made of cardboard or paper, are inserted. The last frame is connected to an upper cover plate and a lower cover plate together with the honeycomb inserts. It is thus possible to form relatively thick furniture elements which - compared to conventional blockboard or chipboard - weigh considerably less and are cheaper to manufacture.
  • the lower weight results in easier handling, lower package weights, a reduction in packaging effort and improved handling. A particularly favorable effect is that the lower weight makes it easier to transport with portable furniture.
  • the invention has for its object to provide a method and an apparatus for producing strip frames for sandwich panels, which can be used easily and reliably in an automated manner.
  • longitudinal bars and cross bars are fed to a joining station by means of a transport device.
  • the longitudinal ledgers are already arranged parallel to one another and are at a distance which is greater than the length of the transverse ledgers to be used.
  • the result is a ladder-like arrangement.
  • the supply of two longitudinal bars is necessary, but strip frames for sandwich panels with several longitudinal bars are also possible.
  • the dimensioning of the longitudinal bars and the transverse bars is also variable over a wide range, so that it is possible to produce relatively large sandwich panels in one operation, which can subsequently be divided into individual smaller sandwich panels by severing the longitudinal bars or the transverse bars.
  • the longitudinal bolts and the first transverse bolt are transported against a first end stop. This can be moved vertically so that it can be removed from the transport path after the last has been joined. There are further stops between the longitudinal bars can be moved vertically one after the other in order to position the subsequently carried cross bars in the joining station accordingly. This results in an exact alignment of both the longitudinal bars and the transverse bars in the joining station.
  • a gluing device is provided in order to glue the joining surfaces.
  • the entire last frame can be released and transported immediately after pressing. Since, according to the invention, the crossbars of associated stops are positioned, and since, according to the invention, the position of the longitudinal bars in the transport direction is determined by the end stop, an exact alignment and positioning of the individual longitudinal bars and crossbars is ensured, which is additionally calibrated by the lateral pressing / transverse pressing. This results in an excellent dimensional stability of the last frame, which is much higher than that of manually produced last frames.
  • FIG. 1 is a partial perspective sectional view of a sandwich panel according to the prior art
  • FIG. 11 is a partial perspective sectional view of a sandwich panel according to the invention.
  • 12a to 12c show a simplified representation of the work processes for producing a sandwich panel according to the invention using the joining method according to the invention or the joining device according to the invention.
  • the sandwich plate u shown in FIG. 1 contains an upper cover plate 1 which is placed on a strip frame. This consists of two parallel bars 2 parallel to one another and at least two cross bars 3.
  • a honeycomb insert 5 is in the compartment formed from the longitudinal bars 2 and the cross bars 3 inserted, which consists of paper or cardboard and in plan view has a honeycomb-like structure, preferably hexagonal honeycombs.
  • the reference number 4 indicates a reinforcing insert, which can also be used, for example, in a door for fitting fittings, door locks or the like.
  • longitudinal bars 2 and a plurality of cross bars 3 are fed in parallel to one another on a first conveyor belt 10 of a transport device 6.
  • the arrangement of the longitudinal bars 2 and the transverse bars 3 is transferred to a second conveyor belt 11 of a joining station 7.
  • the longitudinal bars 2 and the first cross bar 3a lie against the end stop 8.
  • a middle further stop 9a is moved downward in the direction of the second conveyor belt 11.
  • a second cross bar 3b moved in the transport direction thus comes to bear against the stop 9a, as is shown in the middle of FIGS. 9 and 5. '
  • the figures show further stops 9c and 9d, which can optionally be used to form variants of the last frame.
  • FIG. 11 shows a perspective partial sectional view of the structure of a sandwich panel according to the invention with a strip frame which comprises longitudinal bars 2 and cross bars 3, not shown.
  • a honeycomb insert 5 is inserted into the last frame, the gripping device according to the invention described above being used for the insertion.
  • the strip frame is then glued to an upper cover plate 1 and a lower cover plate 2.
  • An upper veneer 11 can be applied to the upper cover plate 1, the upper side of the lower cover plate 6 can be provided with a lower veneer 12.
  • the longitudinal bars and cross bars can be made from materials such as MDF, solid wood or chipboard.
  • the top cover plate 1 and the bottom cover plate 6 can have thicknesses of 5 to 10 mm.
  • An upper and lower veneer 11 or 12 can be glued to the surfaces (outer surfaces) of the upper cover plate 1 or the lower cover plate 6.
  • other laminating materials foil, lacquer or the like
  • the top cover plate 1 and the bottom cover plate 2 can be made of hardboard, chipboard or HDF. It goes without saying that the side visible surfaces can also be veneered or covered with laminating material or the like.
  • FIGS. 12a to 12c The invention is described below on the basis of a schematic representation of an overall system in conjunction with FIGS. 12a to 12c:
  • longitudinal bars 2 and cross bars 3 are first fed into station 01.1 and positioned in a ladder-like manner.
  • the longitudinal bars 2 are received in a stack magazine, the cross bars 3 are placed on circumferential conveyor belts at a distance from one another.
  • the longitudinal bars 2 are at a distance from the cross bars 3.
  • the longitudinal bars and cross bars are transferred to a conveyor belt 8.
  • a plurality of stops 9 are provided, which can be moved vertically and are used for the frontal engagement of the longitudinal bars 2 and for the respective positioning of the cross bars 3.
  • the longitudinal bolts 2 and the transverse bolts 3 are accordingly stopped and positioned.
  • the conveyor belt 8 is stopped.
  • the joints are glued accordingly (not shown).
  • the last frame is joined by lateral pressing.
  • the adhesive fixes the longitudinal bars and cross bars 2, 3 immediately, so that at the station 01.3 a finished last frame can be transferred to another conveyor belt.
  • the compressed material of the honeycomb insert is drawn into a honeycomb expander dryer 02.1 from a honeycomb plate supply 02.2.
  • the previously folded honeycombs are set up and dried by the warm air so that they are fixed.
  • a cutting device at the end of the honeycomb expander dryer 02.1 cuts corresponding fixed dimensions of the honeycomb inlays 5 from the endless honeycomb carpet thus created. The size of these corresponds to the compartments of the last frame.
  • the separated and cut honeycomb inserts 5 are fed to a station 03.3. There you will be lifted by grippers 12, which are provided with gripper fingers pointing downwards, which engage in the honeycomb of the honeycomb inserts 5. After being inserted into the honeycomb insert, the gripper fingers are brought closer together so that they compress the honeycomb insert and thus behave. By transferring the honeycomb inserts 5 hanging on the grippers 12 into the last frame, these are inserted into the last frame in station 03.1. It is inserted on a flat conveyor belt so that flatness is guaranteed.
  • the last frame with the honeycomb inserts used is transferred to a 04.0 inclined roller conveyor.
  • the last frame is positioned exactly.
  • the strip frame is subsequently provided with adhesive in station 05.0 on the top and on the bottom. This is done by means of upper and lower rollers, by means of which the adhesive is applied.
  • the glued strip frame is subsequently transported on a tapered roller conveyor in order to have only a small contact area by means of conically shaped transport rollers so that the glue application on the underside of the strip frame is not impaired.
  • a stack of upper cover plates or lower cover plates is provided, for example by means of the forklift shown.
  • the stack is transferred to a station 06.2.
  • a vacuum lifting unit an upper cover plate or lower cover plate is lifted off in station 06.3 and transferred to station 06.4.
  • an upper cover plate is placed on station 06.5 by means of a vacuum lifting unit 06.8, which is mounted on a portal, while a lower cover plate is transferred to station 06.7.
  • the vacuum lifting unit now grips the top cover plate from station 06.5 and places it on the glued strip frame. After a short press, the vacuum lifting unit lifts the top cover plate together with the last frame and places it on the bottom cover plate in station 06.7.
  • the sandwich panel is now fully assembled.
  • the sandwich plate In the stations 07.0 and 07.8 the sandwich plate is transported on and calender presses 09.1 and 09.2 are fed. This creates a firm bond to the finished sandwich panel. This leaves the calender presses 09.1 and 09.2 and is transferred to a transport station 10.0. From this, stacking takes place in stations 11.2 and 11.3, this being done by means of vacuum lifting units in station 11.1.
