Definitions

  • the invention relates to a machine for processing workpieces made of wood, plastic and the like according to the preamble of claim 1.
  • the furniture parts are shorter, then they remain at the height of the upper spindle, since on the one hand they have been released from the transport roller lying in front of the cover in the transport direction, but have not yet been detected by the subsequent transport roller behind the cover. Only through the next workpiece running through the machine is this workpiece then conveyed into the area of the transport roller behind the covering hood.
  • the invention has for its object to design the generic machine so that workpieces can be processed in a continuous pass through the machine, the length of which is shorter than the distance between the transport rollers lying in front and behind the cover of the upper spindle.
  • the additional rollers which are smaller in diameter, are located between the transport rollers lying in front of and behind the cover or the spindle underneath, so that the smallest workpiece length can correspond to the distance between the axes of these additional rollers. Due to their small diameter, the additional rollers can extend very close to the flight circle of the machining tool sitting on the upper spindle. In this way it is possible in a structurally very simple way, even very much to process short workpieces, the length of which corresponds to the distance between the axes of these additional rollers, in a continuous pass through the machine. The short workpieces therefore do not stop in the area of the upper spindle, but are quickly transported on by the additional rollers.
  • the short workpiece Before entering the cover, the short workpiece is gripped by the corresponding additional roller and further conveyed to the processing tool on the upper spindle. Since the other additional roller sits behind this processing tool with only a small distance in the transport direction, this short workpiece is grasped by it immediately after processing and fed to the subsequent transport roller. With the machine according to the invention, a large number of short workpieces can be processed in the unit of time.
  • a machine table 1 on which a transport path 2 for the workpieces 3 to be machined is provided.
  • a transport path 2 for the workpieces 3 to be machined For transporting the workpieces along the transport path 2 in the transport direction 4, rotatably driven transport rollers 5 are used, which are located at a distance above the transport path 2.
  • the transport rollers 5 are mounted in a known manner on a carrier (not shown) which is also connected in a known manner to a drive with which the transport rollers 5 are rotatably driven.
  • You and / or the carrier are adjustable in height so that their position can be adjusted to workpieces 3 of different thicknesses.
  • the rollers 5 rest on the workpiece 3 to be transported and convey it through the machine in the transport direction 4.
  • the machine has a lower, horizontal spindle 6, on which a cutter head 7 is seated in a rotationally fixed manner. It is used to process the underside of the workpiece 3 as it passes through.
  • the transport path 2 is interrupted accordingly.
  • the machine In the direction of transport 4 at a distance after the spindle 6, the machine is provided with a vertical spindle 8, on which a cutter head 9 is fixed in rotation. It is surrounded by a protective or exhaust hood 10.
  • the rotatably driven spindle 8 with the cutter head 9 can be arranged on the right or left of the workpiece to be machined in the direction of transport 4 of the workpiece. Depending on the position of the spindle 8, the right or left Machined the long side of the workpiece 3 during transport through the machine by the cutter head 9.
  • the machine In the transport direction 4 at a distance behind the spindle 8, the machine is provided with a further vertical, rotatably driven spindle 11, on which a cutter head 12 is seated in a rotationally fixed manner. It is in turn surrounded by a cover or suction hood 13. In the drawing, this spindle 11 is shown in a position folded down by 180 ° for better illustration.
  • the two spindles 8 and 11 are located on opposite sides of the workpiece 3, seen in the transport direction 4. As a result, the two long sides of the workpiece 3 can be machined. It is also possible to arrange the spindle 11 with the cutter head 12 together with the spindle 8 and the cutter head 9 on the same side, so that the workpiece 3 is transported on the right and left when it is transported through the machine by both cutter heads 9 and 11 Long side can be edited.
  • the row of transport rollers 5 is not interrupted in the area of the vertical spindle 11, since this spindle 11 is located in the area next to the row of transport rollers.
  • the machine In the direction of transport 4 at a distance behind the spindle 11, the machine is provided with a horizontal upper spindle 14, on which a cutter head 15 sits in a rotationally fixed manner, with which the upper side of the workpiece 3 is machined during its passage.
  • the cutter head 15 is located under a cover or suction hood 16, which covers it upwards and laterally. Since the cover 16, in the transport direction 4 seen, protrudes beyond the row of transport rollers 5, the transport rollers 5 cannot be provided in the area of this cover 16. The distance between the two transport rollers 5 lying in front of and behind the cover 16 in the transport direction 4 determines the shortest length that the workpieces 3 can have in the conventional machines.
  • the workpieces 3 can be significantly shorter than in the known machines. This can be attributed to the fact that between the two transport rollers 5 lying in front of and behind the cover 16, smaller additional rollers 17 and 18 are provided, the center distance 19 of which is considerably smaller than the center distance between the two transport rollers lying in front of and behind the cover 5. In 1 is shown that the short workpiece 3 by both additional rollers 17 and 18th recorded and thus transported properly. Compared to conventional machines, this enables workpieces to be machined whose length is almost half that of the known machines.
  • the additional rollers 17, 18 are also driven and matched to the speed of the transport rollers 5 so that the workpiece 3 is transported evenly in the area of the cover 16.
  • the additional rollers 17, 18 and the transport rollers 5 have the same peripheral speed.
  • the radius of the additional rollers 17, 18 is substantially smaller than the radius of the transport rollers 5. Seen perpendicular to the transport direction 4, the additional rollers 17, 18 partially protrude into the cover 16.
  • the additional rollers 17, 18 are advantageously mounted on the cover 16. This has the advantage that the additional rollers 17, 18 can be removed together with the cover if, for example, the cutter head 15 on the spindle 14 is to be replaced.
  • the distance between the two transport rollers 5 located in front of and behind the suction hood 16 is selected such that, instead of the cutter head 15 and the suction hood 16 adapted to its flight circle diameter, a cutter head which is larger in the flight circle diameter and has a correspondingly longer suction hood in the transport direction can be used .
  • the result is a conventional machine that does not have the additional rollers.
  • a holder 28 is fastened on the cover 16, on which actuating devices 29 and 30 for adjusting the gear housing 22, 23 and thus the additional rollers 17, 18 are provided. With these adjusting devices, the additional rollers 17, 18 can be adjusted in height for fine adjustment to workpiece tolerances.
  • the actuating device 29 has a threaded spindle 31 which is connected at one end to the gear housing 22 in an articulated manner.
  • the threaded spindle 31 projects through an upwardly angled end 32 of the holder 28 and through a nut 34 provided with a star grip 33, which is rotatably mounted on the holder end 32 in a known manner.
  • the threaded spindle 31 is displaced relative to the holder end 32, as a result of which the height of the gear housing 22 and with it the additional roller 17 is adjusted relative to the cover 16.
  • the actuating device 30 has an actuating cylinder 35, preferably a pneumatic cylinder, the piston rod 36 of which is articulated on the gear housing 23 via a link 37.
  • the actuating cylinder 35 itself is on the in Transport direction 4 attached to the rear over the cover 16 projecting end of the holder 28.
  • the spindle 14 with the cutter head 15 and the cover 16 is arranged in a known manner on a support 38, only indicated in the drawing, which extends in the region above the cover.
  • an adjusting device is accommodated in a known manner, with which the spindle 14 and the cover 16 can be adjusted in height.
  • the spindle 14 can also be easily adapted to workpieces 3 of different thicknesses.
  • the additional rollers 17, 18 are connected to the cover 16 in the manner described, they are adjusted in height in the same manner when the spindle 14 is adjusted.
  • the additional rollers 17, 18 can be adjusted by means of the adjusting devices 29, 30 relative to the spindle 14 for fine adjustment to workpiece tolerances.
  • the additional rollers 17, 18, like the transport rollers 5, are pivoted so that they can adapt to unevenness on the top of the workpiece 3.
  • Such a pendulum mounting of the transport rollers 5 is known in such machines and is therefore not described in detail.
  • the distance 19 between the axes of the additional rollers 17, 18 is greater than the distance between the additional rollers and the adjacent transport roller 5. This ensures in any case that the workpieces 3 can be reliably transported in front of and behind the spindle 14.
  • FIG. 1 there is a further lower, horizontally lying spindle 39 in the transport direction 4 behind the additional roller 17, on which a cutter head 40 is seated in a rotationally fixed manner. With it, the workpiece 3 can be reworked on its underside.
  • the transport path 2 is interrupted for the passage of the cutter head 40 in a known manner.
  • the additional roller 18 lying in front of the cover 16 in the inlet direction is advantageously a toothed roller made of steel or cast iron or similar material. It ensures a positive engagement in the workpiece 3, which is thereby reliably fed to the cutter head 15.
  • the other additional roller 17 lying in the transport direction 4 after the cutter head 15 has an elastic, resilient outer surface in order to avoid damage to the machined upper side of the workpiece. With this additional roller 17, the workpiece 3 is transported non-positively.
  • cutter heads In addition to cutter heads, other suitable processing tools such as milling cutters can also be used on the various spindles.
  • the additional rollers 17a, 18a are not arranged on the cover 16a, but rather on a carrier 41 and 42 each via the respective adjusting device 29a, 30a.
  • the additional rollers 17a, 18a are arranged in relation to the cover 16a in the same way as in the exemplary embodiment according to FIG. 1. Thus, even very short workpieces 3 can also be transported perfectly with this machine.
  • the additional rollers 17a, 18a are pressed onto the workpiece 3 with the necessary force.
  • This force can be hydraulic, pneumatic or mechanical, e.g. Be generated by at least one compression spring.
  • the additional rollers 17a, 18a can be adjusted in height with the adjusting devices 29a, 30a for fine adjustment to workpiece tolerances.
  • the carriers 41, 42 are mounted on the feed bar (not shown) which is known per se and, in accordance with the previous embodiment, is connected in a known manner to a drive with which the transport rollers are driven for rotation.
  • the speed of the additional rollers 17a, 18a can be adapted to the speed of the transport rollers by means of the transmission gears housed in the gearboxes 22a, 23a so that all rollers have the same peripheral speed.
  • the cover 16a has cutouts through which the additional rollers 17a, 18a protrude. If the cutter head 15a located in the cover 16a is to be exchanged for a cutter head with a larger flight circle diameter, then a replacement of the cover 16a is not necessary.
  • the additional rollers 17a, 18a are clocked up or removed. A conventional machine then results, in which the additional rollers 17a, 18a are not effective or are not present.
  • FIG. 2 is otherwise the same as the embodiment according to FIG. 1.
