Definitions

  • the invention relates to a processing device for severing and / or crushing a section of a coating material according to the preamble of claim 1.
  • a processing device for severing and / or crushing a section of a coating material according to the preamble of claim 1.
  • Such a processing device is known from the DE 10 2004 019 316 A1 known.
  • Such a processing device can be provided on a processing machine for applying coating material to a workpiece, which is used, for example, for processing, in particular plate-shaped, workpieces in the field of the furniture and component industry.
  • the coating material previously applied to a workpiece is reworked such that it is flush with the wide surfaces of the workpiece.
  • a first post-processing step the one that initially protrudes over the wide area is Coating material milled flush almost to the workpiece surface of the wide area.
  • a second post-processing step the milled surface is smoothed using a scraper, creating a chip that is separated from the coating material. This chip is also called drawing chip.
  • the chip length usually corresponds to the length of the coating material. If, for example, it is a workpiece with a length of 2 meters, on the narrow side of which a corresponding coating material has been applied, a 2 meter long chip is separated from the coating material. This can lead to a malfunction in the processing machine, in particular if the separated chip reaches certain units of the processing machine. To prevent this, a device is used with which the drawing chip can be shredded.
  • the DE 10 2004 019 316 A1 relates to a device and a method for edge processing.
  • the processing device comprises a processing device for cutting off an edge section in the case of plate-shaped or strip-shaped workpieces, as a result of which at least one chip is formed.
  • the device is characterized in that it has a chip-receiving section and a chip-forming device in which the at least one chip can be changed geometrically.
  • the chip-forming device is in particular a shear edge and a cutting tool, in particular a milling tool.
  • the invention aims to provide a device with which the separation of different chips can be ensured, and in particular also thin and / or tough chips can be safely separated. Furthermore, a high level of user-friendliness is to be achieved by a simple setting.
  • a coating material in the sense of the invention means in particular an element which is applied to one side of a workpiece to be coated.
  • it is a narrow surface coating, which is also referred to as edge material.
  • the coating material can be made from a, in particular thermoplastic, plastic material, veneer, metal, or the like.
  • the processing device can have a feeler device and a scraper arranged adjacent to the feeler device. In this way, the processing device and a workpiece can be guided relative to one another, so that an engagement of the scraper removes a chip / drawing chip from the coating material, in particular narrow surface coating material.
  • the processing device can be moved and the workpiece can be held. In this case it is Machining device, for example, attached to a processing unit that is moved along a workpiece or around a workpiece. Alternatively, the workpiece is moved and the processing device is held.
  • the processing device is set up to cut off and / or shred a section of a coating material, in particular a drawing chip.
  • the processing device comprises a cutting tool with a movable cutting edge.
  • the cutting edge can rotate about an axis of rotation. It is further preferred that the cutting tool has several cutting edges.
  • the cutting tool is designed as a milling tool.
  • the processing device comprises a cutting plate with a cutting edge.
  • the cutting edge is set up and / or arranged to interact with the cutting edge of the cutting tool in order to sever and / or shred a section of a coating material. It is provided that the position and / or orientation of the cutting edge can be changed in at least two directions.
  • the machining device according to the invention has the advantage that the cutting gap, which is formed between the cutting edge and the cutting edge during operation, can be adjusted in parallel. This means that it can be adjusted to a specific dimension over the entire length or width. It is therefore possible to safely cut through even thin or tough chips.
  • the cutting edge of the cutting tool can be rotated about an axis.
  • the cutting edge is thus movable and can cooperate with the cutting plate in order to separate and / or shred a portion of the coating material.
  • a first direction is a translatory direction and a second direction is a rotational direction.
  • the cutting edge can thus be brought closer to the effective area of the cutting edge and precisely aligned in a further step or in parallel. Alignment in the rotational direction can take place before operation of the machining device in order to align the cutting edge for operation so that a parallel cutting gap is created.
  • the position and / or orientation of the cutting edge can be definable for operation.
  • the position and / or orientation of the cutting edge can thus be set before starting operation.
  • the cutting plate is connected to a displaceable slide.
  • the slide can be moved in a guide in a translatory direction.
  • the cutting plate can be attached to a pivotable carrier plate, it being preferred that the carrier plate can be fixed by an adjusting device, such as a screw. In this way, a simple change in the position and / or orientation of the cutting edge is made possible and the operator is thus assisted in setting the machining device.
  • the carrier plate can be pivoted about a hinge, the hinge preferably being a, in particular metallic, hinge.
  • the hinge can be designed as an area with a reduced material thickness.
  • the carrier plate and the carriage could be formed in one piece. A reliable and inexpensive construction can thus be provided.
  • the cutting insert is aligned during operation such that the cutting edge touches the cutting insert.
  • the cutting gap is 0 mm, so that a particularly safe cutting of thin drawing chips is guaranteed.
  • the cutting plate can be made as a resilient element, so that the cutting plate is deflected when it comes into contact with the cutting edge.
  • the cutting insert can interact with the cutting edge without causing damage to the cutting insert.
  • the cutting plate can have two projections, between which the cutting edge of the cutting plate extends.
  • the projections can serve as an insertion aid in order to securely hold a drawing chip.
  • the cutting edge first touches the projections tangentially and presses the cutting plate away accordingly. It can further be provided that the cutting edge first touches the projections of the cutting plate. This prevents wear on the cutting edge.
  • the machining device has a feed device for feeding a lubricant into the region of the cutting insert.
  • the feed device can be tubular, for example, and eject an atomized lubricant in the direction of the cutting plate.
  • the invention also relates to a processing machine.
  • the processing machine is equipped with a post-processing tool, in particular a milling tool, for flush machining Coating material and a processing device according to one of the preceding aspects.
  • the invention relates to a method for operating a processing device which is provided for severing and / or comminuting a section of a coating material, for example a processing device according to one of the preceding aspects, or a previously mentioned processing machine.
  • the method comprises the steps: moving a cutting plate having a cutting edge in a first direction to a cutting edge of a cutting tool, aligning the cutting edge in a second direction.
  • the cutting edge can be aligned before or during the operation of the processing device. For example, alignment can be done by rotating the cutting edge around an axis. Alternatively or additionally, it is possible for the cutting edge to touch the cutting insert during operation, it being preferred for the cutting insert to be manufactured as a resilient element.
  • FIG 1 A processing device 10 is shown, with which, as described below, a coating material B applied to a workpiece W is first smoothed and the drawing chip produced in this way is comminuted.
  • This in Figure 1 Workpiece W shown is held by means of a clamping device.
  • the processing device 10 is attached to a movable unit or slide (not shown) which can be moved, for example, in several spatial directions.
  • the processing device 10 can be a section or part of a processing machine with which the workpiece W is provided with the coating material B and subsequently processed in the area of the processing device 10.
  • the workpiece W can be held in the area of the processing device 10 at least between the application of the coating material B and the post-processing.
  • the workpiece W can be, for example, a chipboard or lightweight board provided on the broad sides with a coating.
  • the coating material B mentioned is applied to the narrow side of the workpiece W.
  • the processing device 10 comprises a base 11 on which a probe shoe 12 (probe device) is attached.
  • the feeler shoe 12 comprises a touch surface 12a, which a workpiece W during a relative movement between the workpiece W and the Processing device 10 leads such that a scraper 13 can remove part of the coating material B.
  • the scraper 13 of the processing device 10 is arranged such that the scraper 13 can process a corner region of the coating material B.
  • the scraper blade 13 is attached to the base 11 and adjacent to the feeler shoe 12.
  • the machining device 10 further comprises a cutting plate 16 which is arranged in a stationary manner during the machining process.
  • the cutting plate 16 has a cutting edge 17 which, in the present embodiment, extends in the vertical direction or essentially in the vertical direction.
  • a rotating cutting tool 18 is provided adjacent to the cutting plate 16, the rotating cutting tool 18 comprising a plurality of cutting edges 19 arranged in the circumferential direction.
  • three cutting edges 19 are provided on the cutting tool 18, the number of cutting edges 19 not being limited to this.
  • the cutting edges 19 are preferably provided interchangeably on the cutting tool 18.
  • the cutting tool 18 rotates in the opposite direction to the direction of movement of the workpiece W about an essentially vertically oriented axis of rotation (in the illustration of FIG Fig. 1 counterclockwise). Due to the rotary movement of the rotating cutting tool 18, the cutting edges 19 are temporarily brought into the vicinity of the cutting plate 16, so that the cutting plate 16 and the respective cutting edge 19 of the rotating cutting tool 18 cooperate between the cutting gap Cutting edge 17 and cutting edge 19 to cut Z present.
  • the shortest distance between the cutting plate 16 and the respective cutting edge 19 defines the cutting gap. Since the cutting edges 19 are periodically guided into the area of the cutting tool 18 by their arrangement on the cutting tool 18, the drawing chip Z is crushed.
  • the cutting plate 16 is mounted on a carrier plate 15.
  • the carrier plate 15 is located on a carriage 20, the carriage 20 being able to be moved in a translatory direction. By moving the carriage 20 in the direction of the cutting tool 18, the cutting plate 16 can be moved relative to the cutting tool 18 and thus the cutting gap between the cutting edge 17 and the cutting edge 19 can be varied / adjusted.
  • the carrier plate 15 is connected to the slide 20 by means of a metallic hinge 21.
  • the hinge 21 is part of the carrier plate 15 and represents an area with a relatively low material thickness. By applying force to the carrier plate 15, the latter can be rotated relative to the slide 20.
  • a tension and compression screw 22 is also provided on the support plate 15 as an adjusting device, so that when the screw 22 is loosened, the support plate 15 can be pivoted about an axis 15a of the hinge 21. In this way, the cutting edge 17 can be aligned in a rotational direction by a rotary movement. Since the hinge 21 is formed in one piece with the carrier plate 15 and the slide 20 in the exemplary embodiment, a relatively small but extremely precise pivoting movement of the carrier plate 15 can be carried out.
  • the parallelism of the cutting edge 17 of the cutting plate 16 can thus be set relative to the cutting edge 19 of the rotating cutting tool 18.
  • a uniform distance for example a cutting gap of 0.02 mm
  • FIG. 2 a second embodiment of the invention is shown.
  • the same or similar components of the processing device 10 'according to the second embodiment are identified by the same reference numerals as in the first embodiment.
  • the processing device 10 'of the second embodiment of the invention differs from that in FIG Figure 1 Processing device 10 of the first embodiment shown in that a cutting plate 16 'designed as a resilient element is attached to a translationally movable carriage 20'.
  • the reversibly bendable cutting plate 16 ' comprises a cutting edge 17' which is provided in a U-shaped recess in the cutting plate 16 '. Due to the U-shaped configuration, the cutting plate 16 'comprises two opposite projections 16a, which serve as an insertion aid for the drawing chip Z. A cutting edge 17 'of the cutting plate 16' extends between the projections 16a.
  • feed device 30 for a lubricant in the vertical direction below the spring-loaded cutting plate 16 ' compressed air being fed in the present exemplary embodiment with a mixed lubricant in the direction of the spring-loaded cutting plate 16'.
  • the Feeding device 30 is tubular and its opening is aligned in the direction of the cutting plate 16 '.
  • the cutting plate 16 ' is made of spring steel and is of plate-shaped design.
  • the cutting edge 17 ′ of the cutting plate 16 ′ is arranged essentially tangentially to the cutting edge 19.
  • the cutting edge 19 first hits the projections 16a tangentially and presses the cutting plate 16 'away accordingly.
  • the cutting plate 16 ' moves resiliently in the spring direction F by contact with the cutting edge 19.
  • the punctiform or linear contact between the cutting edge 17 'and the cutting plate 16' remains.
  • the drawing chip Z is cut by the interaction of the cutting edge 17 'and the cutting edge 19 of the cutting tool 18.
  • the cutting edge 17' is set parallel to the cutting edge 19 of the cutting tool 18, so that the parallelism is achieved by the running in of the cutting plate 16 '.
  • the cutting gap between the cutting edge 17 'and the cutting edge 19 is essentially 0 mm in the second embodiment.
