Definitions

  • the invention relates to a gang saw with an up and down saw saw, which carries a plurality of clamped in the frame, parallel saw blades, with a straight guide upstream of the saw blades, which receives the block-like, side guide surfaces having clippings between side guide walls, and with one Feed drive for the clippings.
  • Parquet timbers are supplied in commercially available block sizes, so that the sawing devices used to manufacture the parquet slats must be set to this block size.
  • Circular saws with several circular saw blades are usually used as sawing devices, which ensure a correspondingly high throughput due to their comparatively high cutting speed.
  • a disadvantage of such circular saws is that with a usual lamella thickness of, for example, 3.5 to 4 mm, the cutting width of the circular saw blades corresponds to approximately half the lamella thickness, which means the loss of a lamella compared to thin-cut saws when machining a wooden block.
  • the invention is therefore based on the object of avoiding these deficiencies and of specifying a sawing device with the aid of which several clippings can be sawn simultaneously and precisely into lamellae with low cutting losses.
  • the invention achieves the object in that the straight guidance is divided by side-by-side guide walls into side-by-side, parallel guide channels for one block of clippings each, that the saw blades are combined into groups according to the guide channels and that either the guide walls and the Baffles protrude between the saw blade groups or side guides are provided between the saw blade groups for the saw blockers that form into the clippings blocks and are inserted into the frame.
  • the outer lamellae of the sawn clippings receive a sawn and a planed surface, which can lead to an arching of the lamellae.
  • the guide walls and the guide walls can only extend to immediately in front of the saw blades, while saw chippers are provided between the saw blade groups in the frame frame, which take on the management task for the clippings in the area of the saw blades, so that not only a sawn outer surface caused by the sawing, but also a lateral outer guide for the outer slats is also obtained.
  • machining the outer surfaces of the clippings a higher accuracy with regard to the thickness of the outer lamellae can be achieved.
  • the design of the guide channels can be very different, because it is only a question of a corresponding longitudinal guidance of the clippings between the guide walls and the guide walls used between the guide walls. Particularly simple constructional relationships result, however, if the guide walls and the guide walls are inserted into cross frames enclosing the guide channels, which do not hinder the feed of clippings.
  • the guide walls and the guide walls themselves can advantageously be arranged interchangeably, on the one hand to take wear into account and on the other hand to be able to change the width of the guide channels by means of guide walls of different thicknesses. Such an adjustment of the guide channel width to the respective requirements could of course also be achieved by a side adjustment of the guide walls.
  • Feed rollers which form a floor support for the clippings blocks, can be used for the clippings feed. If the height of the guide walls and the guide walls should protrude above the block height, then either the guide walls and the guide walls can have corresponding recesses for the feed rollers or they protrude between the walls. The same applies to pressure rollers cooperating with the feed rollers on the top of the block.
  • the guide channels can be aligned with the saw blades of the saw frame, which are grouped together in accordance with the guide channel arrangement, in order to saw the blocks of cut material conveyed in the individual guide channels into lamellae, the guide channels can be adjustably mounted transversely to the feed direction.
  • the saw cutters in the area of the guide walls can each consist of two saw blades separated by a bar.
  • the saw blades which are not themselves rigid, are stiffened accordingly by the strip connected to them, which is a prerequisite for the desired block guidance.
  • the saw cutters can also consist of a saw blade that is stiffened by a bar.
  • a floor support in the form of a wooden or plastic strip running transversely to the clippings blocks can be provided in the area of the teeth of the saw blades for the clippings, into which the kerf of the saw blades continues, so that tearing of the joint edges in the area of the clippings area is effectively prevented by such a strip.
  • the frame saw shown consists essentially of a saw frame 1, which is mounted in a frame 2 and can be driven up and down in a conventional manner.
  • a plurality of saw blades 4 are clamped in parallel next to one another, the saw blades 4 being combined into saw blade groups 5, as can be seen in particular from FIGS. 1 and 2.
  • guide channels 6 For guiding the material to be cut, several guide channels 6 are provided, which result between two outer guide walls 7 and guide walls 7a inserted between these guide walls 7. These walls 7 and 7a are held in cross frames 8 into which the walls 7 and 7a are interchangeably inserted.
  • the frame To hold the cross frame 8, the frame has 2 mounting brackets 9, on which the frame is supported by support webs 10.
  • the guide channels 6 are aligned with respect to the saw blade groups 5 so that the saw blades 4 of the individual saw blade groups 5 each subdivide the width of the associated guide channel 6 evenly.
  • the clippings 11 to be sawn can be sawn into lamellae 12 of the same thickness if the clippings 11 have a width corresponding to the width of the guide channels 6 and form lateral guide surfaces which, in cooperation with the side walls 7 and 7a of the guide channels Ensure exact straight guidance of the clippings blocks 11. Therefore, the clippings 11 must be precisely machined on the side surfaces before they are fed to the frame saw, which is generally the case.
  • a feed drive with driven feed rollers 12 is provided, which form the floor support of the clippings blocks 11 in the region of the guide channels 6.
  • Pressure rollers 14 are arranged opposite these feed rollers, which ensure a vibration-free guidance of the clippings if a corresponding adjustment of these pressure rollers 14 is ensured. Since the height of the guide walls 7 is greater than the height of the clippings blocks 11, either the guide walls 7 and the guide walls 7a or the feed rollers 13 or the pressure rollers 14 must have corresponding recesses in order to hold the clippings blocks 11 between the feed rollers 13 on the one hand and the pressure rollers 14 on the other hand to be able to clamp. 4, the feed rollers 13 form 6 conveyor rings 15 in the region of the guide channels, while the pressure rollers 14 have a continuous, elastic jacket, so that the guide walls 7 and the guide walls 7a must be provided with recesses 16 for the pressure rollers 14.
  • the lateral guidance of the material to be cut in the area of the saw blades 4 is not achieved by the elongated walls 7 or 7a, but by saw chipper 17, which are formed by saw blades 4a connected to strips 18 and in which Frame 3 of the saw frame 1 are used, so that the outer surfaces of the clippings blocks 11 undergo sawing which not only enables the same type of lamellas regardless of the original processing of the clippings block 11, but also tolerance compensation with regard to the block dimensions.
  • the strips 18 give the saw blades 4a, which act as chippers, the lateral bending stiffness required for guiding the material to be cut.
  • a floor support for the clippings blocks 11 in the form of a wooden or plastic strip 19 running transversely to the clippings blocks can be provided in the area of the teeth of the saw blades, as shown in FIG 5 and 6 are drawn in and is indicated by dash-dotted lines in FIG. 4.
  • the kerfs continue, so that the bar 19 results in a tearing of the joint edges preventing the cut material.
