Definitions

  • the invention relates to an edge banding machine for gluing an edge onto a workpiece, with at least one processing unit for the upper longitudinal processing of the glued edge, which is arranged pivotably on an axis parallel to the guide direction of the workpiece.
  • Edge banding machines are used for gluing edge material made of wood or wood-like materials onto boards made of wood or wood-like materials.
  • the panels are moved through the machine at a constant speed and the edging material is fed from a roll or in pre-cut strips or strips and permanently connected to the panel.
  • the glued edges are then processed lengthways by various processing units arranged one behind the other depending on the task.
  • processing units include Flush trimming units or fine trimming units.
  • Edge banding machines for example the "Kantomat” edge banding machine from Paul Ott GmbH, are known in which the processing units are arranged one behind the other on a horizontally arranged machine base. The processing units are screwed onto a flat, machined horizontal surface. Depending on the task, the tools of the units must be movable in the vertical or in the vertical and horizontal directions in order to be able to adapt to the machining edge of the workpiece.
  • Flush milling units are used to pre-mill the glued edge and ensure a flush transition from the workpiece to the edge. They must therefore be fed in the vertical direction, ie normal to the workpiece.
  • a feeler roller connected to the flush milling unit presses the workpiece with a certain preload force so that the cutter head of the flush milling unit is at a constant distance from the surface of the workpiece.
  • the flush trimming unit is guided vertically in a linear guide and fed manually.
  • Fine milling units are used for finish milling glued and usually pre-milled edges, the processing essentially consisting in the production of bevels with different bevel thicknesses and bevel angles as well as radii.
  • the fine milling units are guided both horizontally and vertically in linear guides.
  • a generic edge banding machine in which an upper and a lower processing unit for dressing the edge are each attached to a swing arm which can be pivoted about a horizontal axis in the vertical direction.
  • Guide shoes are attached to the outer end of the swing arms.
  • the swing arms are biased against each other by means of a coil spring.
  • the distance between the processing units can be adjusted so that it is somewhat less than the thickness of the workpiece to be processed.
  • this setting is very cumbersome.
  • the invention has for its object to provide an edge banding machine with structurally simple means, the processing units for the longitudinal processing of the glued edge can be adjusted in and out with little effort in the vertical direction and this movement with e.g. Pneumatic cylinders can be easily accomplished and automated.
  • This object is achieved on the basis of the generic prior art in that the workpiece is guided between an upper roller pressure and a conveyor along a stop, that the upper roller pressure is vertically adjustable in height and that the upper axis of the processing unit for the upper longitudinal machining of the edge is attached to the upper roller pressure so that the processing unit for the upper longitudinal machining of the edge can be pivoted relative to the upper roller pressure.
  • This configuration of the edge banding machine according to the invention enables the processing units to be fed vertically only by pivoting on the axis relative to the upper roller pressure.
  • the edge banding machine according to the invention is therefore structurally very simple.
  • the processing units can be quickly set to the appropriate workpiece thickness by an operator. It has surprisingly been found that the angular misalignment, which is less than one degree, can be neglected.
  • the edge banding machine according to the invention is therefore particularly suitable for edge banding machines which are designed for a low edge thickness.
  • Fig. 1 shows individual work areas of the edge banding machine.
  • the workpiece for example a plate 10
  • the workpiece is introduced along a stop 12 in a guide direction F.
  • the pressure zone D In the guide direction after the stop 12 is the pressure zone D, in which an edge 14 is glued to an end face of the plate 10.
  • the edge 14 is from a roll, not shown fed and deflected via a first driven pressure roller 16.
  • a plurality of pressure rollers 18 are arranged, which serve to press the edge 14 onto the plate 10.
  • a processing zone B is provided in the guide direction of the plate 10, in which a plurality of processing units (not shown in FIG. 1) process the glued edge 14.
  • Processing units for the longitudinal processing of the edge are, for example, flush milling units, radius and chamfer milling units (fine milling units), scraper units or edge cleaning units.
  • a trimming unit can also be attached so that the edge is cut to length in the transverse direction.
  • the stop 12 can be adjusted transversely to the guide direction F.
  • the stop 12 is set so that its stop surface lies in a plane with the glue surface of the edge 14 in the pressure zone B.
  • the processing edge 20 in the processing zone is fixed. It lies in one plane with the pressure points of the pressure rollers 18.
  • the edge banding machine has a roller carrier 24 of a top roller pressure 22 (FIG. 3) which is designed as a shaped tube and which, as indicated by the arrows, can be adjusted in the vertical direction.
  • the upper roller pressure 22 can be set in accordance with the thickness of the plate 10.
  • upper cross members 34 are attached normal to the roller carrier 24.
  • an upper axis 36 is mounted so that it is parallel to the roller carrier 24 and parallel to the guide direction F (Fig.1) Workpiece 10 extends in a horizontal plane.
  • a frame 32 which carries a conveyor device which is formed by a chain drive 28 (FIG. 3).
  • Lower cross members 38 are also attached to the frame 32 normally to the frame 32.
  • the lower cross members 38 carry a lower axis 40 which runs parallel to the upper axis 36 and to the guide direction F.
  • pressure rollers 22 are attached to the underside of the roller carrier 24 and exert pressure on the surface of the inserted plate 10.
  • the plate 10 rests on the chain plates 30 of the upper run of the chain drive 28, which is attached to the frame 32.
  • the plate 10 is conveyed by the chain 28.
  • an upper cross member 34 which extends perpendicularly from the roller carrier 24, has a downwardly extending section, in which the upper axis 36 is fastened, for mounting an upper flush milling unit 48 at its end remote from the roller carrier 24 .
  • the flush milling unit 48 is articulated on the axis 36.
  • the flush milling unit 48 has a bearing block 35.
  • a pivot plate 49 is fastened to the bearing block 35 perpendicular to the axis 36.
  • the drive motor 62 of the flush milling unit 48 is fastened on the swivel plate 49, on the end of which facing away from the upper axis 36 a cutter head 52 for processing the edge 14 is arranged.
  • the height of the axis 36 is selected so that the cutting edges of the cutter head 52 in the processing position shown in FIG. 3 run parallel to the surface of the plate 10.
  • the flush milling unit 48 has a feeler roller 60 which controls the cutter head 52 of the flush milling unit 48 in a known manner so that the transition from plate 10 to the edge remains flush.
  • a piston rod 58 of a pneumatic cylinder 56 is articulated on the swivel plate 49 in the area of the cutter head 52.
  • the pneumatic cylinder 56 is articulated at its end opposite the piston rod 58 to an angle 54 fastened to the frame 24.
  • the lower cross member 38 attached to the frame 32 has at its end opposite the frame 32 an upwardly extending section 41 in which the lower axis 40 is fastened.
  • a flush milling unit 50 is also pivotably mounted on the axis 40. The height of the axis 40 is selected so that the cutter head 52 of the flush milling unit 50 runs parallel to the underside of the plate 10 in the machining position shown in FIG.
  • the flush milling unit 50 is connected to a pneumatic cylinder 56 in the same way as the upper flush milling unit 48.
  • the lower flush milling unit also has a feeler roller 60.
  • the pneumatic cylinder 56 is at its end opposite the piston 58 a cross strut 54 extending perpendicularly from the frame 32.
  • the lower flush milling unit 50 is also connected to a feeler roller 60.
  • the piston rod 58 is fully extended in the processing position of the flush milling unit 48.
