Definitions

  • the invention relates to a method according to the preamble of patent claim 1 and to a machine according to the preamble of patent claim 6.
  • a method and a machine with essentially the same features is known from document AT-PS 263 335. This is because elongated workpieces, such as panel-like wooden strips, are profiled on their opposite, mutually parallel narrow surface sides, the workpieces being conveyed to and from the profiling zone by means of transport devices and acted upon by an overpressure device. In the area of the profiling zone, tables are provided on which the workpieces slide flat.
  • ceiling panels are machined, which are provided with harmonizing profiles on at least two mutually parallel, narrow surface sides.
  • the panels can be connected to one another in a form-fitting manner by installing the above-mentioned profiles.
  • the workpieces transported on the slideway of the associated machine are not positively guided transversely to the direction of travel.
  • the friction between the upper workpiece sides facing away from the slideway and the upper pressure device is used.
  • the profiling tools are arranged opposite each other on both sides of the slideway in such a way that the forces exerted on the workpieces cancel each other out as far as possible transversely to the direction of passage. Nevertheless, it cannot be avoided that the finished, i.e. profiled ' narrow surface sides of the workpieces are not exactly parallel to one another. In the case of ceiling panels, greater tolerances can be accepted with regard to this parallelism, because the gap between the gaps usually does not interfere.
  • the ceiling panels in the connection area can also be provided with rabbet-like heels or the like in order to increase the creative scope by a different height structure of the finished ceiling. As a result, irregularities with regard to the parallelism of the joining sides of ceiling panels can be concealed to a considerable extent.
  • the invention is therefore based on the object of providing a method and a machine of the type mentioned at the outset in which the parallelism of the opposing, profiled narrow surface sides of the panels in question can be maintained with high precision and correspondingly low tolerances.
  • the plate-shaped workpieces cannot run in the lateral direction when they pass through the profiling zone, that is to say are exactly guided by the interaction of the guide groove provided on the workpieces and the machine-side straight guide device in the predetermined direction of travel, in or parallel to which the two-sided profiling of the narrow surface sides of the workpieces is carried out.
  • the at least one guide groove on the workpieces has to be made in a separate operation, also must a suitable area for this can be found on the workpieces, but a much better result is achieved compared to such a guide, in which the workpieces are acted upon in the area of their narrow surface sides lying in the direction of flow during the passage.
  • the guide grooves are placed at places on the workpieces where machining is not carried out or is no longer carried out.
  • the leading engagement in the guide grooves can take place over the entire length of the workpieces in the direction of passage.
  • the workpieces have a considerable length in the direction in which they are passed through, which provides particular guidance security.
  • the interaction between guiding the workpieces according to the invention and conveying them on a slideway also offers the particular advantage of being able to achieve high throughput speeds when profiling the workpieces.
  • the plate-shaped workpieces have a wide-area side that is visible in the installed position and is provided with a surface coating that determines the appearance.
  • This visible side of the panels is also referred to as the good side, which must not be impaired by the incision of the guide grooves.
  • the guide groove in such panels is arranged on the broad surface side remote from the quality side, with which a particularly advantageous side effect is achieved.
  • This side effect is particularly useful for elongated, board-like panels as a floor covering because the direction of passage is in the longitudinal direction of the panels and this also applies to the guide grooves provided.
  • the guide groove creates a space in which the moisture or moisture can collect in the installed position. This is particularly important when the panels are placed on a surface with their entire surface facing away from the good side.
  • the guide grooves also counteract bending of the panel edges.
  • the one or more guide grooves are preferably cut in on the broad surface side of the workpieces which, during the passage, rests on the slideway of the continuous machine.
  • the incision of the guide grooves is expediently carried out immediately before the profiling process before it runs onto the machine-side straight guide device, so that there is no need for further alignment of the workpieces if the corresponding machining tool and the straight guide device are aligned.
  • This has a particularly advantageous effect if a central guide groove is cut on the overlying side, particularly in the case of elongate workpieces which lie in the longitudinal direction with their longitudinal direction.
  • the workpieces are guided in a sliding manner by means of the guide grooves and the machine-side straight guide device.
  • This cannot have a detrimental effect on the workpieces because they pass through the continuous machine for profiling on their narrow surface sides only once.
  • the straight guide device can consist of a continuous guide rail made of a suitable material which is sufficiently resistant.
  • it is possible to seg entate the guide rail or to execute it in individual sections which are arranged at a distance from one another.
  • Fig. 1 shows a schematic cross section through the profiling zone of a machine for the lateral profiling of plate-shaped workpieces
  • FIG. 2 shows a schematic longitudinal section through that area of the machine according to FIG. 1 which is upstream of the profiling zone. Best way to carry out the invention
  • the slideway 1 shows a slideway 1 which extends in the direction of travel of the machine.
  • the slideway 1 here has two mutually parallel sliding surfaces spaced apart from one another, each of which is flat and which is generally oriented horizontally.
  • Workpieces 2 which are plate-shaped and which are primarily elongated, board-like panels from which a floor covering is assembled are transported on the slide 1 in the direction of passage.
  • the slidability of the workpieces 2 on the slideway 1 can be promoted by an air cushion of negligible height, and for this purpose air outlet nozzles 13 are provided in the plane of the slideway 1, via which the necessary supporting air between the overlying broad surface side of the workpieces 2 and Blown slideway 1.
  • the escape of the supporting air has the further advantage that the direction of conveyance of the chips produced when the workpieces 2 are profiled can be influenced.
  • the feed of the workpieces 2 on the slide 1 in the traveling direction is effected by means of an upper printing device 3, 4.
  • This device comprises conveyor belts and slings 3 which act on the remote from the 'chute 1, that is overhead broad surface side of the workpieces 2 rubbing.
  • Appropriate guide and pressure rollers are len 4 are provided, which ensure an exact guidance of the belt 3 in the direction of travel for the workpieces 2.
  • profiling units are arranged in the region of a profiling zone, of which only two profiling tools 6 engaging against the workpieces 2 are shown in FIG. 1.
  • profiling tools 6 machine the so-called narrow surface sides of the plate-shaped workpieces 2, a groove 7, for example, being attached to one of these sides and a tongue 8 to the opposite side. Accordingly, the tools 6 are rotating molding tools, such as milling cutters.
  • the edge height of the workpieces 2 is scanned by means of feeler elements 9, The height orientation of the profiling tools 6 is controlled by changing their position.
  • a guide groove 10 preferably running centrally in the longitudinal direction, is made on the workpieces 2. brought, which can also be seen in Figure 2.
  • the guide groove 10 has mutually opposite flanks, in particular it has a rectangular cross section.
  • This guide groove 10 is attached in an area of the machine which lies in front of the profiling zone with the profiling tools 6 in the direction of passage.
  • a sawing device 12 as shown schematically in FIG. 2 is used for this.
  • the processing tool of this saw device 12 is at least one circular saw blade, the level of which lies in the direction of travel for the workpieces 2.
  • a straight guide device 11 in the form of a guide rail extends through the profiling zone of the machine, in which the profiling tools 6 are arranged, which are located on both sides of the slideway 1, which can be segmented or can be designed in individual sections spaced apart from one another, which 'is aligned with the at least one circular saw blade of the sawing device 12th
  • the straight guide device 11 expediently extends up to the sawing device 12 counter to the direction of passage. Because the workpieces 2 are to run with their guide grooves 10 onto the straight guide device 11, that is to say they are picked up and guided thereon.
  • the saw device 12 with its circular saw blade lies in the region of the slide 1, and the circular saw blade of the saw device 12 projects as far as the depth of the broad surface sides of the workpieces 2 lying below - Kl ⁇
  • the straight guide device 11 also protrudes upwards over the slideway 1, but the protrusion is somewhat less than the depth of the guide grooves 10 cut into the lower sides of the workpieces 2.
  • the straight guide device 11 is aligned with the saw device 12, see above that the workpieces 2 are conveyed over the saw device 12 into the profiling zone via the top pressure device 3, 4, the straight guide device 11 coming into engagement with the guide grooves 10 of the workpieces 2 shortly after the saw device 12.
  • the width of the straight guide device 11 transverse to the direction of passage is adapted to the width of the guide grooves 10 of the workpieces 2 with narrow tolerances, at least in the region of the profiling zone.
  • the workpieces 2 are thus guided virtually without play transversely to the direction of flow in the region of the profiling zone. Above all, the workpieces 2 cannot yield to the machining pressure exerted on them by the profiling tools 6 transversely to the direction of passage
