Definitions

  • the invention relates to a processing device, a processing machine and a method for processing coating material, in particular narrow-surface coating material, which is applied to a workpiece.
  • a processing device such a processing machine and such a method is or will be used in the woodworking industry.
  • So-called form milling units which process a coating material applied to a narrow surface of a workpiece on the front edge of the workpiece, the rear edge of the workpiece and on the corners of the workpiece with one or more milling tools.
  • a milling tool can be guided along the workpiece contour by means of a feeler roller.
  • the device includes a post-processing unit with a first processing tool, in particular a milling tool, for processing a workpiece edge, and with a reference device for determining a reference position for the infeed positioning of the first processing tool relative to a workpiece section being processed. That The post-processing unit and the reference device are set up to be able to process at least two edges of a workpiece with a different edge overhang relative to the adjacent workpiece surface.
  • Processing machines are also known that have one or more trimming units that cut off excess coating material. During a cutting process, a section of a coating material is cut off at the workpiece front edge and the workpiece rear edge, and the overhang of the coating material is thus significantly reduced.
  • the aim of the invention is to provide a processing device for processing coating material, in particular narrow-surface coating material, which has increased flexibility with a compact design. There is also a requirement for a corresponding processing machine and a corresponding method.
  • a processing device which comprises the features of claim 1 is proposed as a solution. Further preferred embodiments are listed in the dependent claims and the following description.
  • the processing device has a carrier on which a first processing unit, in particular a milling unit, for shaping a coating material and a second processing unit for separating a coating material are provided.
  • Form processing is performed to form, for example, a radius or a chamfer on an edge of a workpiece, which may be provided with a coating material.
  • a shape machining is in particular a machining, especially form milling.
  • a form machining can also be a non-cutting machining.
  • the first processing unit can be equipped with a milling tool for this purpose.
  • the carrier can be designed in one piece or can comprise several components.
  • the second processing unit is equipped with at least one sawing device for this purpose.
  • machining processes can thus be combined in a compact manner in one machining device, and the machining device can thus be designed to be more flexible. This also means that a processing machine that has such a processing device requires a shorter processing length and space can thus be saved.
  • a coating material applied to a workpiece can be processed by means of the processing device.
  • a coating material can be made of a plastic material, or be in the form of veneer, solid wood or the like.
  • Such a processing device can be used in particular in the woodworking industry, for example in furniture production.
  • the carrier is attached to a horizontal slide that can be moved in a feed direction.
  • the carrier having the first processing unit and the second processing unit can be moved in the feed direction to perform respective processing operations of the first processing unit and the second processing unit.

  • the second processing unit can be detached when processing for separating a coating material is not required for a certain period of time.
  • the first processing unit can also be removed.
  • first processing unit and/or the second processing unit can be detached from the processing device without tools. If the second processing unit is removed or released without tools, a lock can be used which can be unlocked without an operating tool, in particular by hand. In particular, a quick-release fastener can be used. It is thus possible for the first and/or second processing unit to be removed quickly, with the result that non-productive times can be reduced.
  • the second processing unit comprises at least one sawing device in order to carry out a precise separating cut for separating a coating material.
  • the second processing unit comprises at least two sawing devices, it being preferred for the sawing devices to be driven by a common motor.

  • the variability of the processing device can thus be increased.
  • the second processing unit has at least one movable stop. Furthermore, according to a further variant, it can be provided that the second processing unit has a first movable stop and a second movable stop. With such a stop, the position of a sawing device can be set precisely relative to a workpiece.
  • the at least one stop preferably the first and second stop, can have a feeler device so that the stop or stops can be applied to a workpiece with a defined force.
  • the first processing unit is provided on a first side of the carrier and the second processing unit is provided on a second side of the carrier.
  • a compact yet variable arrangement is thus provided.
  • the second processing unit has at least one pneumatic drive or an electric drive, in particular a servo drive, for actuating the second processing unit.
  • a pneumatic drive can be implemented for cost-effective implementation. Different dimensional depths can be achieved using a servo drive.
  • the second processing unit can be pivotable in order to introduce a bevel into the coating material during the cutting process.
  • the variability of the processing device can thus be further increased.
  • the invention relates to a processing machine which has a processing device according to one of the preceding aspects, and a conveyor device, in particular continuous conveyor device, for bringing about a relative movement between the processing device and a workpiece.
  • a processing machine which has a processing device according to one of the preceding aspects, and a conveyor device, in particular continuous conveyor device, for bringing about a relative movement between the processing device and a workpiece.
  • the invention also relates to a method.
  • the method for processing a workpiece provided with a coating material, in particular a narrow surface coating material, with a processing device, the processing device having a first processing unit for shape processing of a coating material and a second processing unit for separating a coating material, comprises: Selecting the first processing unit and/or the second processing unit for processing the coating material.
  • processing can be carried out. For example, a coating material that is applied in a protruding manner on a workpiece is first severed with the second processing unit, so that the protrusion is reduced. Shape machining of the coating material can then be carried out with the first machining unit, for example in order to introduce a radius or a chamfer.
  • the processing device 1 comprises a first processing unit 10 and a second processing unit 20 which are accommodated on a common carrier 2 of the processing device 1 .
  • the first processing unit 10 is arranged on a first side of the carrier 2
  • the second processing unit 20 is provided on a second side of the carrier 2 .
  • the second processing unit 20 is detachably attached to the carrier 2 by means of a quick-release fastener and can be removed from the carrier 2 if necessary.
  • the carrier 2 is mounted on a horizontal slide 3, which can be moved in a feed direction V via a guide device (not shown).
  • a workpiece is moved along the feed direction V by means of a conveyor device (not shown).
  • the processing device 1 can thus be moved along the feed direction V, in which a workpiece is moved by means of the conveying device, in order to carry out processing operations on the workpiece while the workpiece is being moved.
  • the first machining device 10 includes a tool holder in which a milling tool 11 is accommodated.
  • the milling tool 11 is driven in rotation and is set up to carry out shape machining on a workpiece.
  • a radius or a chamfer can be introduced into an edge of a workpiece with the milling tool 11 .
  • Machining residues occurring during machining can be removed by means of a suction hose 14 .
  • the first processing device 10 is also equipped with a feeler roller 12 .
  • the feeler roller 12 is arranged in such a way that the feeler roller 12 defines an infeed position of the milling tool 11 relative to the workpiece section being machined when it travels over a workpiece surface. In this way, the workpiece edge being processed can be milled flush with the workpiece surface.
  • the first machining unit 10 is accommodated on the carrier 2 by means of a tool slide 13 such that it can be displaced in a direction Z perpendicular to the feed direction (in 1 up or down).
  • the feeler roller 12 moves in the Z direction due to the mobility of the tool slide 13. Since the workpiece is held on the conveyor device (not shown) and moves in the feed direction V, the movement of the tool slide 13 causes a Adjusted to the thickness of the workpiece.
  • the second processing unit 20 is provided, which is constructed as a so-called trimming unit.
  • a cross-cut motor with a continuous motor shaft is connected to a cross-cut saw 21 (first sawing device) on the inlet side and to a second cross-cut saw 22 (second sawing device) on the outlet side.
  • a chop cut is triggered via a pneumatic drive 27, in which the first chop saw 21 and the second chop saw 22 penetrate into the coating material attached to the workpiece and protruding from the workpiece and cut through it.
  • the pneumatic drive 27 swivels out a unit comprising the first cross-cut saw 21 and the second cross-cut saw 22 .
  • a first chop stop 23 and a second chop stop 24 are provided, adjustable horizontally to the chop saws 21, 22.
  • the first crosscut stop 23 is moved vertically from bottom to top by means of a first pneumatic cylinder 25 and the second crosscut stop 24 by means of a second pneumatic cylinder 26, so that the crosscut stop 23, 24 that is issued comes into engagement with a narrow surface of a workpiece.
  • a workpiece is moved in the feed direction V by the conveyor (not shown) and held on the conveyor.
  • the horizontal slide 3 travels with the first processing unit 10 with the workpiece 2 .
  • a first workpiece edge is now milled flush by moving the milling tool 11 in the Z direction over the tool slide 13 is moved relative to the carrier 2. Since the feeler roller 12 is in contact with the workpiece, the machining position of the milling tool 11 is determined.
  • the horizontal slide 3 is then moved counter to the feed direction V and machines a second workpiece edge.
  • a third workpiece edge can be milled by moving the milling tool 11 in the Z direction relative to the carrier 2 .
  • the processing device 1 is then moved faster than the workpiece in the feed direction V, so that a relative movement occurs between the horizontal slide 3 and the workpiece.
  • a fourth edge of the workpiece is machined with the milling tool 11 .
  • the processing device 1 is braked and returned to a starting position in order to be able to process a subsequent workpiece.
  • the first trimming stopper 23 is moved for a front narrow surface of a workpiece. Shortly before the incoming workpiece reaches the first crosscut stop 23, the movement of the processing device 1 in the feed direction V is adjusted to the movement of the workpiece and in the course of this the first crosscut stop 23 is applied to the front narrow surface of the workpiece with a predetermined scanning force. During the movement of the processing device 1 with the workpiece in the feed direction V, the first crosscut saw 21 is moved in such a way that the protruding coating material is cut off, with the contact of the first crosscut stop ensuring a defined distance from the front narrow surface of the workpiece.
  • the processing device 1 then accelerates so that the first crosscut stop 23 is removed from the workpiece again and the first crosscut stop 23 can be returned to a basic position.
  • the processing device 1 moves back a little on the conveying path or the processing device 1 is braked while the workpiece moves on.
  • the second crosscut stop 24 (crosscut stop for the rear edge) reaches the rear narrow surface of the workpiece, the second crosscut stop 24 is raised and the processing device 1 is synchronized with the movement of the workpiece in such a way that the second crosscut stop 24 rests against the edge of the workpiece with a predetermined scanning force . Subsequently, the second chop saw 22 is moved to cut off a protruding coating material.
  • the processing device 1 After the trimming has been carried out on the rear narrow surface of the workpiece, the processing device 1 is braked and the second trimming stop 24 is thus disengaged from the workpiece. The processing device 1 can now be returned to a starting position and process a subsequent workpiece.
  • the first processing unit 10 remains in a rest position.
  • the second processing unit 20 for separating a coating material may be pivotally configured according to a modification of FIG.
  • the second processing unit 20 can be pivoted about an axis 29, in particular by means of a drive (not shown). In this way, an oblique cut can be carried out during a separating process and a chamfer can thus be introduced into the coating material.
