Definitions

  • the invention relates to a continuous sawing device with a plurality of saw blades for splitting or grooving workpieces, which are preferably plate-shaped, according to the preamble of claim 1.
  • each saw blade has its own drive motor and its own adjustment, so that the strip widths can be adjusted during operation of the machine from the outside.
  • the disadvantage here is the high cost, for Each unit to provide its own drive motor.
  • the corresponding footprint of the drive motor determines the minimum possible strip width to be cut, whereby the variability of the saw is impaired.
  • the invention is based on the technical problem of providing a continuous sawing device which has a high variability at low standstill and changeover times.
  • the invention is based on the idea of designing a continuous saw device for splitting or grooving plate-shaped workpieces in such a way that the rotary drive and the saw width setting are largely decoupled from each other.
  • the invention provides that in a continuous sawing device of the type mentioned, the sawing elements are connected to the drive shaft so that they are displaceable in the longitudinal direction of the drive shaft.
  • the displaceability of the saw elements along the drive shaft can be achieved in the context of the present invention in various ways. According to one embodiment of the invention, however, it is provided that the saw elements form fit in the direction of rotation of the drive shaft are connected, so that it is possible to dispense with clamping elements, clamping screws or the like and it is possible that the sawing elements can be moved at any time - even during operation - along the drive shaft.
  • the drive shaft and sawing elements can in principle have any desired cross section, which can also have depressions, projections or the like, for example.
  • the drive shaft has a deviating from a circular cross-section, in particular an at least approximately polygonal cross-section.
  • the sawing elements have at least one saw blade and a flange connected thereto.
  • the sawing elements can in principle be connected directly to the respective drive shaft, it is provided according to a development of the invention that the sawing elements are respectively connected to the drive shaft via a transmission element.
  • a transmission element allows the compensation of manufacturing tolerances and a reduction of the components that must be replaced when changing a saw blade or saw element. It is particularly preferred that the transmission elements are positively connected to the respective saw element, whereby the advantages already discussed above are also achieved.
  • the sawing elements are each rotatably mounted in a bearing element which is attached to a base frame of the continuous saw device. It is particularly preferred that the bearing elements in the longitudinal direction of the drive shaft along the base frame are displaceable, so that the sawing elements can maintain a fixed relationship with the respective bearing elements even with an adjustment of the saw width.
  • the adjustment of the respective sawing elements or bearing elements can be done in the context of the present invention in any way, for example, by manual adjustment of each component.
  • it further comprises an adjusting device by means of which the saw elements can be adjusted along the shaft.
  • the adjusting device for example, work manually-mechanically, for example in the form of a crank provided with an adjusting spindle.
  • the adjusting device has an adjustment, which is in communication with the saw elements and / or bearing elements and is controllable by a control device.
  • a continuous sawing device 1 as an embodiment of the present invention is shown schematically in Fig. 1 in a side view.
  • the continuous sawing device 1 is used for splitting or grooving plate-shaped workpieces (W), which are preferably at least partially made of wood, wood-based materials, plastics or the like.
  • workpieces can be, for example, wooden boards, parquet or laminate floors, etc.
  • the continuous sawing apparatus 1 first has a conveying device 2 for conveying plate-shaped workpieces W in a passing direction, wherein a plate-shaped workpiece W is shown schematically and partially in FIG.
  • a conveying device 2 may be, for example to act a belt, belt or chain conveyor.
  • a plurality of sawing elements 4 are arranged, which are all mounted on a common drive shaft 6b.
  • the drive shaft 6b is operatively connected to a drive 6a, wherein the connection may be direct or optionally also indirect, for example via toothed belts or the like (see Fig. 3).
  • the sawing elements 4 are connected to the drive shaft 6b such that they are displaceable in the longitudinal direction of the drive shaft 6b. This is achieved in the present embodiment in that the sawing elements 4 are positively connected to the drive shaft 6b in the direction of rotation of the drive shaft 6b.
  • the drive shaft has a cross section deviating from a circular shape, more specifically, an approximately polygonal cross section.
  • a transmission element 8 is arranged between these components whose inner cross-section fits positively to the drive shaft 6b and whose outer cross-section is positively connected to the drive shaft 6b Saw elements 4 fits. It is sufficient in the region of the connection between the drive shaft 6b and transmission element 8 game available that a longitudinal displacement of these components is possible, while at the same time a torque about the axis of the drive shaft 6b can be transmitted.
  • the sawing elements themselves are each formed in the present embodiment by a saw blade 4a and a flange 4b, which is fixedly connected to the saw blade 4a.
  • the embodiment of the flange 4b shown in FIG. 2 enables a relatively large engagement and support surface to be provided between the saw element 4 and the associated transmission element 8 with the O-rings 10 provided therebetween.
  • the configuration of the flange 4b shown in FIG. 2 allows the sawing elements 4 to be rotatably and easily rotatably supported by a bearing element 12 mounted on the base frame 14 of the continuous sawing device shown in FIG. In this case, the rotatable mounting of the sawing elements 4 or flanges 4b can be achieved in the bearing elements 12, for example by a ball bearing 20 or the like.
  • the bearing elements 12 are slidable via suitable guides along the base frame 14 in the longitudinal direction of the drive shaft 6b.
  • the continuous sawing device further comprises an adjusting device 16 which in the present embodiment has a plurality of rotatably mounted spindles which are connected to the sawing elements 4 and / or the bearing elements 12 and can be adjusted from outside the continuous saw device, for example manually or via a suitable drive.
