Definitions

  • the invention relates to a device for separating adjacent, cross-divided panel strips behind the dividing line of panel sizing saws, with the features of the preamble of claim 1.
  • the individual, adjacent plate strips are shifted by a feed device in the feed direction by different feed paths before each cut and then before cutting on the Machine table defined in front of the cutting line.
  • both stationary and lifting and lowering roller rails are provided.
  • the axis of the rail rollers is slightly inclined to the longitudinal axis of the rail.
  • the lifting rails are then raised to such an extent that their rollers slightly protrude beyond the first support level or define a second support level to accommodate the plate formats.
  • the plate formats are then moved or separated from one another during feed movements in the lateral direction.
  • This construction thus requires two groups of roller rails, each with different roller arrangements, with a lifting device, which is technically complex and correspondingly cost-intensive.
  • the invention has for its object to provide a device in an embodiment according to the preamble of claim 1, which makes it possible to dispense with both lifting and lowering roller rails and differently positioned rollers on certain roller rails.
  • the construction according to the invention is thus characterized by a uniform design of the roller rails which are to be installed in a common plane.
  • the pivotable arrangement of part of the roller rails and the horizontal, from a position parallel to the feed direction of a panel sizing saw into an oblique position to this, on the one hand allows plate strips with mutually adjacent separating edges that are parallel to the cutting line when the pivotable roller rails are set parallel to Feed direction to promote to a transfer station, such workpieces maintain their relative position to each other exactly.
  • the different plate formats that occur when dividing colors can be moved apart sideways by swiveling roller rails or their inclines horizontally during the feed movement, so that a separation gap is created between adjacent plate formats and thus prevents the plate formats from getting caught.
  • roller rail adjacent to the angular ruler all other roller rails will be provided so that they can be pivoted (claim 3), so that the plate formats can also be separated from one another by extensively divided division images.
  • a preferred embodiment of the invention is the subject of claim 4. This makes it possible to set the desired distances between adjacent plate formats by appropriate choice of the rail pivot angle.
  • Another great advantage of this construction is that the length of the pivotable roller rails can be chosen to be relatively small. This in turn enables an arrangement of the roller rails according to claim 5 and thus to let the roller rails begin immediately behind the dividing line.
  • the main advantage of this is that plate formats cannot twist immediately behind the dividing line during feed.
  • FIG. 1 designates as a whole the device according to the invention, that of a panel saw 12 on the output side assigned.
  • the latter has a saw table 14 with, for example, a saw unit traveling under a table, which is not shown for the sake of simplicity.
  • the saw table 14 is divided in the longitudinal direction by a sawing slot defining a dividing or sawing line 16, from which at least one circular saw blade of the saw unit emerges for the panel division.
  • the device 10 is to be regarded as a horizontal extension of the saw table 14 and takes over from it during the advance of a workpiece plate to be divided, for example, two or more plate strips 18, 20 or in a further sawing operation into individual plate formats 22 and 24, transverse plate strips 18, 20 , which will be discussed below.
  • the device 10 is equipped with a plurality of roller rails 26 of the same design, the present exemplary embodiment of the invention e.g. comprises four groups a, b, c and d of such roller rails 26.
  • Each roller rail 26 carries, for example, five pairs of supporting rollers 28 of the same diameter, which are mounted in the same horizontal plane.
  • roller rails 26 of the two roller rails groups a and b which are adjacent to one another and at right angles to one another and at right angles to one another, extend parallel to the feed direction and a machine-fixed stop ruler 30 extending in the same direction
  • the roller rails 26 are the two Roller rail groups c and d can each be pivoted about a vertical pivot axis 32 from a position aligned with the roller rails 26 of roller rail groups a and b into an inclined position (angle ⁇ ) which promotes away from the straightedge 30 and can be locked in this position.
  • roller rail group c this preferably does not apply to the roller rail 26 adjacent to the stop ruler 30.
  • the grouping of the roller rails 26 allows the roller rails 26 of the rail groups c and d adjoining the saw line 16 to be designed to be relatively short, with the advantage of arranging them on the saw table 14 in the presence of a waste flap 34 thereon and thus close to the saw line 16 can start (see Fig. 2).
  • the pivot axis 32 is assigned to this rail end. It is received by the waste flap 34.
  • the pivotable roller rails 26 of both rail groups c and d can be pivoted together into an identical inclined position via an adjusting device.
  • the roller rails 26 are preferably pivotable in groups.
  • one adjustment device can be provided for each rail group, wherein the adjustment device can be designed as desired.
  • each roller rail 26 is assigned an adjustment device formed by a double-acting, preferably pneumatically actuatable cylinder unit 36, the cylinder units 36 being connected in series or connected to a common compressed air line 38.
  • the device works for the color division of workpiece plates as follows:
  • a first splitting operation e.g. rectangular workpiece plates parallel to their longitudinal direction divided into individual plate strips 18, 20, which can be different in width.
  • the resulting plate strips 18, 20 parallel to the stop ruler 30 reach the roller rails 26 during the plate advance.
  • the pivotable rail groups c and d are to be adjusted such that their roller rails 26 are aligned with those of the two roller rail groups a and b. This ensures that the plate strips 18, 20 maintain their relative position to one another during the feed.
  • the plate strips 18, 20 are transported further offset by 90 ° and, again lying side by side, are divided into different plate formats 22 and 24 in a second splitting operation transverse to their longitudinal direction.
  • the individual plate strips 18, 20 are to be moved in a known manner by different paths in the feed direction B and C before each separating cut.
  • the roller rails 26 of the rail group d that receive the individual formats 24 of the plate strip 20 are pivoted by an angle ⁇ about the pivot axis 32 such that the individually occurring plate formats 24 differ from the plate formats 22 of the transversely divided plate strip 18 first in the lateral direction, according to FIG. 1 to the right, moved away by an amount e and then by taking it over through the rail group b again in parallel to the plate formats 22 in the feed direction C.
  • stacked workpiece plates can also be divided in this way.
  • the pivotability of each roller rail 26 of both rail groups c and d enables a lateral separation of plate formats 22, 24 with different width dimensions of plate strips 18, 20 to be divided transversely.
  • roller rails each have to accommodate one of the plate strips that do not lie against the stop ruler 30, and must be set at different angles to one another in order to prevent plate formats produced from these plate strips from moving laterally move away from each other.
