Definitions

  • the invention relates to a cutting device for edge banding machines according to the preamble of claim 1.
  • Known cutting devices of this type are used to separate protruding edge ends, particularly in the case of coated edge bands, which are glued to the narrow side of a plate-shaped workpiece.
  • the moving parts are actuated by compressed air cylinders.
  • a compressed air connection is therefore necessary for the edge banding machine, which together with the maintenance unit for the compressed air means that the machine becomes more expensive.
  • the object of the present invention is therefore to create a capping device of the type mentioned, in which all functions can be carried out by electrical components.
  • the housing 2 of the trimming device is attached to a side wall 1 of an edge banding machine, not shown.
  • a plate-shaped workpiece 3 is conveyed by a conveyor device, not shown, in the direction of arrow 4 through the edge banding machine and is already glued to a edge band 5, the ends 5 'of which protrude from the front and rear narrow surface 3' of the workpiece.
  • a slide 7 is slidably mounted in the housing 2 on the two guide rods 6. 2 also shows, carriage 7 carries a plate-shaped bracket 8, guide bolts 9 being fastened in the carriage 7 and engaging in slots 10 of bracket 8.
  • the console 8 can be moved perpendicular to the feed direction 4 of the workpiece 3 against the action of a compression spring 11. This is supported on one side on a nose 12 of console 8 and on its other side on the head 13 of a screw 14 connected to the carriage 7.
  • a guide block 15 is fastened on the console, in which a cut frame 18 consisting of the two plates 16 and 17 is guided.
  • the guide block 15 is held together by the two bolts 19 and the plates 16 and 17 have slots 20 through which the bolts 19 extend. These thus simultaneously serve as a stop for the cutting frame 18, which is pressed in the rest position by a compression spring 21 in the direction of the workpiece 3.
  • Compression spring 21 is supported on one side on the cut frame 18 and on the other side on the head 22 of a screw 23 connected to the guide block 15.
  • the two plates 16 and 17 each have a window 24 in which the cutting knife 25 is arranged.
  • the guide block 15 is provided on its front side facing the workpiece 3 with a run-in slope 26.
  • a driver member 29 designed as a one-armed lever is pivotally mounted, the pin 30 of which engages in a groove 31 of the console 8.
  • Another stop pin 32 cooperates with a stop surface 33 of cut frame 18 so that the latter during its replacement movement
  • Console 8 lifts off workpiece 3 via driver member 29.
  • the tightening force of the electromagnet 27 can advantageously be changed by dividing the magnetic coils so that this tightening force can be adapted to the thickness and width of the edge band 5.
  • a toothed belt 35 is connected to the latter via a pin 34 and can be driven by an electric motor 37 via a slip clutch 36.
  • pushbutton switches 38 and 39 connected to the housing 2 and a pushbutton switch 41 connected to a bridge 40 of the edge banding machine, the function of which will be described below, are provided for controlling the latching device.
  • slide 7 actuates pushbutton switch 38, with which electric motor 37 and electromagnet 27 are switched off.
  • the console 8 and the cutting frame 18 are thus under the action of the two compression springs 11 and 21 in their immersed position.
  • a conveyor device moves the workpiece 3 in the direction of arrow 4, with the edge 5 'first coming into contact with the guide block 15 via the bevel 26 and shifting it backward by a small amount.
  • Key switch 41 is actuated by workpiece 3 without first triggering an effect.
  • the electromagnet 27 After actuation of the button switch 39 by carriage 7, the electromagnet 27 is energized, its armature 28 attracts the cut frame 18, the cut knife 25 separates the edge overhang 5 '.
  • Pushbutton switch 39 has simultaneously switched the electric motor 37 to return, so that carriage 7 is conveyed back into its starting position via driver element 35.
  • the electric motor 37 is switched off via the pushbutton switch 38, the guide block 15 remains in its raised position as long as the workpiece 3 passes.
  • the electric motor 37 is switched on again, which moves the carriage 7 to the workpiece 3 until the plate 17 strikes the trailing narrow surface 3 '.
  • Another limit switch 42 serves as a safety switch, which switches off the entire edge banding machine when the carriage 7 passes over the pushbutton switch 39.
