Definitions

  • the present invention relates to a processing apparatus according to the preamble of claim 1.
  • a processing apparatus is known from US 2009/0007988 A1 known.
  • Such machines are used for example in the field of furniture and component industry to edit furniture fronts, panels, doors, windows or the like.
  • moulders or planers which can work on four sides.
  • moulders are limited in their functionality, and have the following disadvantages:
  • moulders and planing machines are only partially able to produce so-called "click” or "lock” profiles on the narrow sides of the workpieces, as is customary in the floor area (laminate, parquet) or in wall and ceiling panels, for example, since the machining motors
  • Such machines are not sufficiently pivotable or are not equipped with a sufficiently large adjustment. Therefore, so-called double-end tenoners are used for machining workpiece narrow sides.
  • the workpieces are guided along a fixed strip during the passage, and held against them, so that the workpieces in the area of the processing station can be machined.
  • a workpiece runs curved or "banana-shaped" into such a machine, it will return to its original shape after machining. Furthermore, there is a risk that the workpiece will scratch the said strip.
  • the structure of said double end tenoners has the disadvantage that no machining on the top and bottom (main sides) of the workpiece is possible, since a workpiece on its underside with the moving conveyor track and at the top with a top pressure belt in contact and through this is held.
  • the document DE 20 2006 020 304 U1 discloses a Doppelendprofiler with one or two of chain links formed guide chains as a rotating workpiece support.
  • the in the DE 20 2006 020 304 U1 disclosed chain links are in continuous machines because of the priority in this series production, the high throughput speeds of the workpieces through the machine and previously considered large impact of the lower, rotating workpiece support on the quality of machining used.
  • the workpiece conveyor circulating conveyor chain also runs in a plane which is perpendicular to the transport plane of the workpiece. It is the US 4,457,350 A1 known, which shows a planing machine with processing tools for versatile processing.
  • the DE 10 2006 019 298 A1 relates to an improvement of a double end tenoning machine for working plate-shaped workpieces for the wood and building materials industry.
  • the DE 103 28204 A1 shows a machine for profiling elongated plate-shaped workpieces along the longitudinal edges, wherein the workpieces are passed through an inlet zone and a profiling zone. In the inlet zone there is a stop ruler, on which the workpieces are aligned with one of their longitudinal edges in the direction of passage.
  • Another document is the BE 650 647 A to name a planing machine with which a workpiece can be processed on four sides.
  • the present invention has the advantage that a workpiece can first be processed from the top, for example, planed and / or provided with grooves. Subsequently, the workpieces are conveyed to Schmal vom- or profiling processing in another section of the device according to the invention.
  • the inlet region of the processing device according to the invention has a first and second upper pressure, and the at least one first processing unit is provided in the direction of passage between the further first and second upper pressure. This will ensure that the workpiece during a
  • Machining is held by the at least one first processing unit at the top of the first and second upper pressure, and at the same time takes place by the further conveying path of the inlet region, a support on the underside of the workpiece.
  • the further upper pressure and the further conveying path of the inlet region are independently adjustable in height.
  • the height of the further conveying path of the inlet region By adjusting the height of the further conveying path of the inlet region, the removal provided by the processing unit of the inlet region can be set.
  • the further upper pressure of the inlet region is in each case provided with a multiplicity of roller elements.
  • the additional upper pressure may have one or more belt or chain elements. If several belt or chain elements are provided, these run parallel to the direction of passage.
  • the at least one first processing unit and the at least one second processing unit are planing tools and / or grooving tools.
  • the planing tools are used for a flat material removal, while with a slot tool, for example, a stress relief groove is introduced into a main side of a workpiece.
  • the tools mentioned also include milling tools and saws.
  • the at least one first processing unit of the inlet region comprises a plurality of tools arranged in the direction of passage.
  • the main sides of the workpieces can be gradually removed, or find it successively different types of processing instead, in particular machining operations such as planing, grooving, grinding, sawing or milling.
  • a second processing unit of the inlet region is provided in the direction of passage between the further conveying path of the inlet region and the conveying path of the narrow surface or profiling processing region.
  • the machined by the at least one second processing unit workpiece is largely supported by the chain conveyor.
  • the second upper pressure is provided above the second processing unit, and with the further chain conveyor of the inlet region and the conveying path of the narrow surface or Profiltechniksbearbeitungs Kunststoffs a passage gap is formed.
  • FIG. 1 shows a schematic side view of a preferred embodiment of the present device.
  • the passage direction is in FIG. 1 indicated by an arrow.
  • the processing device shown comprises an inlet region A and a narrow surface or profiling processing region B.
  • the inlet region A and the narrow surface or profiling processing region B are shown in FIG Embodiment connected to each other via a common frame 1. However, they can also each have separate racks, which are arranged such that during operation of the processing device, a continuous flow of material can take place.
  • a circulating conveyor track 2 is provided, which grips a workpiece on its underside and passes along a plurality of possibly pivotable narrow-surface or profiling processing units 3a and 3b.
  • the conveyor track 2 may have one or more conveyor lines. Particularly preferred are two parallel conveyor strands.
  • the conveyor track 2 may be at least one chain track, a belt track or a roller track.
  • the narrow-surface or profiling processing units 3a and 3b can be profile milling or profile grinding devices, for example. With the narrow-surface or profiling processing units 3a and 3b, workpieces are processed in a lateral edge region. This concerns in particular the narrow side of a workpiece, but possibly also partially its main sides.
  • an endlessly circulating upper pressure 4 is provided above the conveyor track 2 such that a gap for a workpiece is formed between the conveyor track 2 and the upper pressure 4.
  • the inlet area A of the device according to the invention comprises a second conveyor track 10, which is arranged in a passage direction of a workpiece in front of the first conveyor track 2.
  • the second conveyor track 10 can support a workpiece as well as the first conveyor track 2 on its underside and convey in the direction of passage.
  • the conveyor track 10 comprises at least one conveyor line, preferably two conveyor lines.
  • first upper roll pressure 11 and a second upper roll pressure 12 are provided in the inlet region A, which are spaced apart in the direction of passage of a workpiece, and each having a plurality of roller elements 11a, 12a.
  • the first upper roll pressure 11 and the second upper roll pressure 12 are independently movable in a vertical direction to form a gap for a workpiece between the second conveyor 10 and the first or second upper roll pressure 11, 12 in this way.
