Definitions

  • the invention relates to a machine for processing workpieces made of wood, plastic and the like, in particular window wood and similar workpieces, according to the preamble of claim 1.
  • the workpiece to be machined is first guided past the cross-profiling tool on one transport path and is machined in the process. If window timbers are used as workpieces, then the end faces of the window timbers are machined, in particular pins are struck, in this first operation.
  • the workpiece is then transported on the other conveyor track, which is at an angle to it, and is guided past the longitudinal profiling tool.
  • the long side of the workpiece is profiled. Appropriate profiling spindles are provided on the long side of this machine for longitudinal profiling. A drive is required for each of the various spindles, which means that the machine is not only expensive to purchase, but also structurally complex to train.
  • the invention has for its object to design the generic machine so that it allows machining of the workpieces on the front and on the long side with a simple design with a minimal number of spindles.
  • the adjustable spindle can be used for cross-profiling and for longitudinal profiling of the workpiece. This makes it possible to save a spindle and the associated drive, so that the machine has a simple structure and is also inexpensive to purchase. If the spindle is in the position required for cross-profiling, in which the cross-profiling tool sitting on the spindle comes into engagement with the workpiece, then the workpiece to be machined is first guided past the spindle for cross-profiling. The workpiece is then guided past the longitudinal profiling tool in its longitudinal direction and processed accordingly.
  • the machine according to the invention is preferably suitable for tenoning and longitudinal profiling, in particular of window timbers and similar workpieces.
  • window timbers it happens that they have to be provided with a further longitudinal profile.
  • the spindle with the adjusting device is now adjusted transversely to the direction of advance of the tools during longitudinal profiling into the position provided for longitudinal profiling.
  • the window timbers are then guided past the spindle in their longitudinal direction and processed accordingly.
  • the machine is used for processing workpieces made of wood, plastic and the like.
  • the machine shown in the drawings is used for machining window timbers and similar workpieces and has at least one stand unit 1, on which at least one profiling spindle unit 2 is arranged on one longitudinal side. It has an upright spindle (not shown) which carries a profiling tool 3 indicated by dash-dotted lines.
  • the workpiece 4 to be machined is guided with its longitudinal side past the profile tool 3 by means of a transport device 7 formed by rollers 6 and is thereby longitudinally profiled.
  • the stand unit 1 also carries on the longitudinal side opposite the profiling spindle unit 2 near the narrow side a circular saw 9 which is rotatably driven by a motor 8 and which is arranged under a cover 10.
  • a circular saw 9 which is rotatably driven by a motor 8 and which is arranged under a cover 10.
  • tenoning spindle unit 12 In the area of the narrow side 11 of the stand unit 1 there is also at least one tenoning spindle unit 12 with a tenoning tool 13 which can be rotated about a vertical axis.
  • a work table 5 which is preferably designed as a roller table. It is provided with at least one (not shown) clamping device in order to be able to clamp the workpiece 4 lying on the roller table.
  • the roller table 5 is shown in its initial position, in which the workpiece 4, which is a window wood in the exemplary embodiment, is still in front of the circular saw 10 at the beginning of the transport path 14. From this starting position, the roller table 5 with the clamped workpiece 4 is guided past the circular saw 10 and the tenoning tool 13 in the transport direction 15. Here, the workpiece 4 is cut to length by the circular saw 10 and machined on its end face during further feed with the tool 13. The roller table 5 finally arrives on the transport path 14 into the end position 16 indicated by dashed lines. The last two drive rollers 6a, 6b located in the inlet area of the roller table 5 are raised when the roller table 5 runs in, so that the workpiece 4 clamped on it is under the drive roller can reach.
  • the clamping of the workpiece 4 on the roller table 5 is released and the workpiece is fed by a drive 17 direction 36 transported.
  • the two drive rollers 6a, 6b are lowered until they come to rest on the workpiece 4. It is then guided past the profiling spindle unit 2 by the drive rollers 6, 6a, 6b and processed on its long side.
  • the roller table 5 in the meantime moves back from the end position 16 to the starting position shown with solid lines, so that in the meantime a further workpiece 4 can be clamped on the roller table.
  • the upright spindle 18 of the tenoning spindle unit 12 can be displaced in the transport direction 15 by the path 19 to such an extent that a tool seated on the spindle 18 can be used for longitudinal profiling of the workpiece 4.
  • the tenoning spindle unit 12 is in a position in which it processes the end face of the workpiece 4 when it is being transported past.
  • the unit 12 has a chip extraction hood 20 for the tenoning tool 13. It has a relatively large diameter, which can be of the order of magnitude between approximately 280 and 450 mm.
  • the vertically standing spindle 18 is connected via a belt or chain drive 21 to a drive shaft 22 running parallel to it.
  • the spindle 18 and the drive shaft 22 are rotatably mounted on an upper slide 23 of a cross slide 24.
  • the upper slide 23 has a cantilevered support 25 and 26 for the spindle 18 and the drive shaft 22.
  • the lower slide 27 of the cross slide 24 can be adjusted in the vertical direction parallel to the spindle 18 and to the drive shaft 22 along a stand 29 by means of a dovetail guide 28.
  • An actuating part 30 is accommodated in it, with which the lower slide 27 and thus also the upper slide 23 can be moved in the vertical direction.
  • the actuator 30 can be a threaded spindle or a lifting cylinder. This makes it possible to set the tenoning tool 13 exactly to the height required for machining the workpiece 4. In the position shown in FIG. 2, the tool 13 can be driven at the maximum speed permissible for the corresponding tool diameter.
  • a transverse adjustment part 31 In order to secure the upper slide 23 against displacement, it is held in its respective position by a transverse adjustment part 31.
  • This actuator 31 can be a threaded spindle or a lifting cylinder.
  • a fixed stop (not shown) can be provided for the position shown in FIG. 2, against which the upper slide 23 is brought into contact.
  • the spindle 18 is displaced horizontally in the direction of arrow 32A into the position shown in FIG. 3.
  • the upper slide 23 of the cross slide 24 is moved by means of the adjusting part 31 until it comes to rest against a stop 32.
  • the stop 32 is preferably formed by a stop bolt which can be screwed in to different degrees.
  • the chip extraction hood 20 and the tool 13 are removed and a tool 34 (FIG. 3) with a smaller diameter for longitudinal profiling of the workpiece 5 and a correspondingly smaller chip extraction hood 35 are mounted.
  • the actuator 31 With the actuator 31, the upper slide 23 can be easily and precisely adjusted.
  • the spindle 18 can be used for longitudinal profiling and repositioning of the workpiece 4.
  • the spindle 18 can be driven so that the direction of rotation of the tool 34 is oriented in the same way as the transport direction 36 of the workpiece 4 during longitudinal profiling.
  • the workpiece 4 is transported from right to left in FIG. 3, the tool 34 rotating clockwise. This synchronism of workpiece 4 and tool 34 reliably prevents tearing out at the end of the workpiece during repositioning.
  • the smaller chip extraction hood 35 for the smaller-diameter tool 34 also has a contact which ensures that when the chip extraction hood is fitted, the spindle 18 with the tool 34 only has the maximum permitted speed can be driven.
  • This contact can be formed in both chip extraction hoods 10, 35 by a cam, which cooperates with a corresponding mating contact when it is placed on, so that the respectively permissible speed for the tool is automatically set inevitably.
  • the workpieces 4 machined on the end faces by the circular saw 9 and by the tool 13 are guided past the tool 34 and possibly the tool 3 in their longitudinal direction by means of the drive rollers 6, 6a, 6b, wherein it is profiled on its corresponding longitudinal side.
  • the spindle 18 with the tool 34 can be controlled so that the tool 34 is in engagement with it over the entire length of the workpiece 4.
  • the control can also be selected so that the tool 34 only comes into engagement with the workpiece 4 at the end of the run.
  • the height position of the spindle 18 can be adjusted with the adjusting part 30.
  • the spindle 18 is first moved with the upper slide 23 in the arrow direction 37 against a stop (not shown) before the height adjustment in order to ensure that the tool 34 is disengaged from the stop area 38. Only then is the lower carriage 27 and thus the spindle 18 in the vertical direction by means of the adjusting part 30 adjusted. Then the tool 34 is moved again against the stop 32 against the direction of displacement 37 by means of the upper slide 23. The workpiece 4 can now be moved past the tools 34 or 3.
