Definitions

  • the invention relates to an edge processing device according to the preamble of claim 1 and an edge processing method.
  • FIG. X designates the processing direction in which the workpiece moves relative to the processing unit.
  • Z designates the vertical direction, vertical to the floor or perpendicular to the broad side of the workpiece 5.
  • FIG. 2 which shows a section along the line B-B through the device 1 from FIG. 1—drawing units 3 are used, which have scrapers 31, 32, which serve to remove excess material from the edge strip 7 that has already been applied, while forming a scraper 8.
  • Such a device with a scraper is also known, for example, from DE 4217 589 A1, EP 1834 744 A2, DE 102015 204 326 A1 or DE 102015218 879 A1.
  • DE 102018 100 934 A1 it is known, for example, to shred the drawing chip immediately after the drawing process. smaller so that it is less likely to get caught in the machine.
  • DE 202019 101 455 U1 discloses a device for removing a long chip. This device has a suction nozzle which is part of a cutting device. The long chip is drawn into the cutting device by the suction device and cut off there.
  • An arrangement for removing long chips is known from DE 102008 048 295 A1, which contains a blowing device which blows on the long chip produced by a scraper and then cuts it off with the aid of a separating device. Targeted blowing is intended to prevent uncontrolled detachment.
  • the workpiece 5 is usually polished by means of a polishing unit 2 which has one or more polishing wheels 21, 22, in particular so-called buffing wheels. Since the drawing unit 3 and polishing unit 2 are arranged one behind the other in the processing direction X of the workpiece 5, the free end of the drawing chip 8 produced during the drawing hangs out over the rear end of the workpiece 5, so that the drawing chip 8 hangs uncontrolled on the edge strip 7. In the process, it can happen that the drawing chip 8 gets caught in the device 1; As a result, the axis of rotation of the polishing wheels 21, 22 can be blocked, for example. Of course, shavings 8 can also get caught in other parts of the edge processing device 1 and lead to damage or blockages.

  • the edge processing device is used for edging the narrow sides of panel-shaped workpieces made of wood or wood substitutes with an edging strip.
  • Edging strips can be both individual strips of edging material and edging strips unwound from the roll. Most of these are made of plastic, but other workpieces are of course also possible.
  • the device according to the invention has a polishing unit with at least one polishing wheel and a scraper device upstream of the polishing unit in a processing direction with at least one scraper for machining the edging strip applied to the workpiece. When applying the edging strip, a drawing chip is created by pulling it off with the scraper.
  • the edge processing device has at least one roller downstream of the drawing unit in the processing direction.
  • This role is according to the invention arranged so close to the polishing wheel that a frictional connection is exerted on a drawing chip generated by the scraper device and reaching the area between the at least one polishing wheel and the roller.
  • the combination of polishing wheel and roller serves to catch the free-hanging drawing chip and clamp it between them. This clamping effect ensures that the drawing chip is guided securely between the roller and the polishing wheel and is removed in a controlled manner from the applied edging strip as a result of the clamping force as the workpiece moves further in the direction of movement.
  • the controlled removal of the drawing chip means that impairments of the type described above are no longer possible.
  • the roller can preferably be arranged directly on the polishing unit. It is just as possible to provide the roller as a component that is mounted separately from the polishing unit. Especially in the last case, a roll according to the invention can be retrofitted without any problems, so that existing systems can be specifically improved by these measures.
  • roller to be mounted so as to be rotatable about an axis of rotation which is inclined relative to the axis of rotation of the polishing wheel.
  • the axis of rotation of the polishing pad and the axis of rotation of the roller may not be parallel to each other.
  • the roller according to the invention is arranged in such a way that its end face, which is in the axial direction, is opposite the edge strip applied to the workpiece on its decorative side.
  • the roller can be made relatively small in terms of its diameter; in principle, for example, it is sufficient if the roller has a diameter which approximately corresponds to the height of the supplied plate-shaped workpiece measured in the vertical direction. Due to the fact that the polishing wheel usually has a relatively flexible surface, sufficient force is still achieved between the polishing wheel and the outer surface of the roller to pick up, hold and tear off a drawing chip that gets between the polishing wheel and the roller.
  • the roller can be driven, but this is not absolutely necessary since the polishing wheel is driven. However, the forces acting on the drawing chip can be set even better via a driven roller, since a specific rotational speed and, if necessary, direction of rotation can be specified.
  • rollers there are different ways to store the roller and also to set the required frictional connection with the polishing wheel.
  • a preferred embodiment can provide that the roller is mounted, in particular on a lever arm, in such a way that it is pressed against the at least one polishing disk. Possibly such a pressing can be accomplished via a spring and some other biasing mechanism.
  • Such a pretensioning mechanism can also be designed to be adjustable, so that the device can be adjusted individually if necessary Edge material, the thickness of the resulting drawing chips or the like can be adjusted.
  • a workpiece described above is connected to an edge strip on a narrow side by means of an edge processing device described above lying on a workpiece transport support.
  • the edge strip is pulled off in one area by means of the at least one scraper, so that a drawn chip is produced. According to the invention, this is caught between the roller and the at least one polishing slide and separated from the remainder of the edging strip as a result of the frictional connection that occurs as a result.

  • the scraper device 3 has at least one, preferably two scrapers 31, 32, which are attached to the workpiece 5 in the area of the edge strip 7. Due to the movement of the edging strip 7 or the workpiece 5 relative to the scraper 31, 32 in a processing direction X perpendicular to the vertical direction Z and transverse direction Y, the drawing chip 8 is produced.
  • the workpiece 5, to which the edging strip 7 is attached lies on it a workpiece transport support 6, in particular a chain conveyor, and is held in place by a top pressure device 4 during conveyance through the edge processing device 1, so that it cannot slip on the workpiece transport support 6.
  • the workpiece 5 reaches the polishing unit 2 as it is transported further in the direction of movement X through the edge processing device 1.
  • at least at least two polishing wheels 21, 22 are components of the polishing unit 2.
  • These two polishing disks 21, 22 are arranged with their driven axes of rotation above or below the workpiece or the edging strip 7, viewed in the vertical direction Z.
  • a roller 9 which is rotatably mounted about an axis D, faces the decorative side of the edging strip 7 .
  • this roller which preferably tapers conically in the transverse direction Y (ie in the direction away from the edge strip 7), lies with its axis of rotation D approximately at the level of the narrow side of the workpiece 5, here in the immediate vicinity of the polishing wheel 21, preferably between two polishing wheels 21, 22, the axes of rotation of which are preferably spaced apart from one another in the direction of movement X.
  • the configuration ensures that the drawing chip 8 reaches the area between the polishing wheel 21 and the roller 9 . This area or gap is preferably selected in such a way that the drawing chip 8 is clamped between the roller 9 and the polishing wheel 21 and is thus held there.
  • the polishing wheel 21, 22 can rotate in synchronism, but also in the opposite direction to the movement of the workpiece.
  • the speed of the polishing wheel 21, 22 can be reduced or increased depending on the feed rate of the workpiece 5.
  • the rotational speed of the polishing wheel 21, 22 is preferably increased when the feed speed of the workpiece 5 increases and correspondingly decreased when the feed speed of the workpiece 5 decreases.
  • the removal of the drawing chip 8 therefore takes place in the area of the roller 9 or polishing wheel 21, so that a correspondingly removed drawing chip 8 can be removed as scrap at exactly this point of the edge processing device 1 according to the invention from the edge processing device 1 in a controlled manner without there being any danger that himself such chips get caught in other parts of the device.
  • a suction device can suck off the separated drawing chips.
