Definitions

  • the invention relates to a woodworking machine, in particular a moulder, according to the preamble of claim 1.
  • Molding machines which have one right, one left, one upper and one lower spindle one behind the other in the direction of transport of the timbers, each of which carries cutter heads.
  • the woods are processed one after the other on the right, on the left, on the upper and on the lower side. If, for example, the knives of one of these cutter heads have to be replaced or jointed, it is necessary to stop the machine during this time. This is downtime relatively high. Even if an entire cutter head is to be replaced, the known moulder must be stopped.
  • the invention has for its object to design the generic woodworking machine so that the downtimes when working on the machine can be kept smaller.
  • the two processing tools mounted on it can be adjusted to a working and a rest position.
  • the one working tool is in the working position, necessary work can be carried out on the other working tool in the rest position without the woodworking machine having to be stopped or the passage of the wood through the machine having to be interrupted.
  • the knives can, for example, be exchanged or jointed at rest. It is also easy to replace the entire cutter head.
  • the processing of the wood does not have to be interrupted during this work.
  • the downtimes of the woodworking machine according to the invention are then only necessary because of the adjustment of the carrier. As a result, very high performances can be achieved with the woodworking machine according to the invention.
  • the woodworking machine is a moulder in which wood is processed.
  • the moulder has cutter heads 1 to 8, which are each seated on spindles 9 to 16.
  • the spindles 9 to 12 are vertical, while the spindles 13 to 16 are arranged horizontally. In Fig. 1, the horizontal spindles 13 to 16 are only indicated by dash-dotted lines.
  • the moulder has a stand 17, on which a table top 18 is arranged, on which the wood is transported through the moulder. On one long side, the table top is provided with stop rulers 19 to 21, against which the woods rest as they pass through the moulder.
  • Feed rollers 22, which are mounted on a carrier 23 of a feed unit 24, are used to transport the woods.
  • a drive motor 25, which is provided on the feed unit 24, is used to drive the feed rollers 22.
  • the height of the support 23 can be adjusted to match different thicknesses of wood.
  • the carrier 23 is formed in two parts and has a support part 26 lying in the area of the vertical spindles 9 to 12 and a support part 27 (FIG. 1) lying behind the horizontal spindles 13 to 16 in the direction of travel of the woods. Both carrier parts 26, 27 are coupled to one another so that they participate in the movements of the carrier 23 to the same extent.
  • the carrier part 27 can be adjusted in the horizontal direction 28 relative to the carrier part 26.
  • the moulder In the area below the two feed rollers 22, which are the first in the direction of passage through the moulder, there is a horizontal dressing spindle 29 with a dressing tool 30 with which the woods are dressed on the underside when they enter the moulder.
  • the table top 18 is interrupted for the passage of the dressing tool 30.
  • the moulder In the direction of travel after the dressing tool 30, the moulder is provided with a slide 32 which can be adjusted horizontally, ie transversely to the transport direction 31 of the timbers, and which carries the two vertical spindles 9 and 10 with the cutter heads 1 and 2.
  • the slide 32 also carries the necessary drive elements for driving the spindles 9, 10 and pressure elements for the passing woods.
  • the slide 32 can be moved between two end positions, so that either the spindle 9 or the spindle 10 can be used to process the woods.
  • the cutter head 1 processes the right side of the timbers in the direction of passage.
  • the cutter head 1 projects between the two stop rulers 19 and 20.
  • the other spindle 10 with the cutter head 2 is in a rest or change position outside of the continuous path or the table top 18.
  • the cutter head 2 can be replaced in this rest position, for example, or equipped with new knives without having to interrupt the processing of the wood.
  • a pressure shoe 33 is assigned to the cutter head 2 and is arranged in the direction of passage 31 in front of the cutter head.
  • the pressure shoe 33 has a vertical pressure surface 34 which runs obliquely to the rear in the transport direction 31. If the slide 32 is adjusted to its other end position, then the knife head 2 is in the working position, while the knife head 1 is in the region outside the transport path and the table top 18 . Then the cutter head 1 can be replaced, for example. The cutter head 2 then processes the left side of the timbers in the transport direction 31.
  • the pressure shoe 33 ensures that the woods are properly pressed against the stop rulers 19 and 20 when they pass the cutter head 2.
  • the slide 32 is provided on its side facing an adjacent slide 35 with a stop ruler 36, along which the woods can be guided as they pass through the molding machine.
  • the stop ruler 36 has a guide surface 37 which is parallel to the transport direction 31 and is provided on a carrier 38 which is approximately triangular in plan. It can be folded away from the position shown in FIG. 1 into a rest position about a horizontal axis (not shown) lying perpendicular to the transport direction 31.
  • a drive (not shown) is provided on the slide 32, for example in the form of a pneumatic cylinder.
  • the stop ruler 36 is provided at the level of the cutter head 2, so that it does not become effective when the cutter head 1 is working.
  • the slide 35 In the direction of transport 31, behind the slide 32, there is the slide 35, which is essentially of the same design as the slide 32.
  • the slide 35 carries the two vertical spindles 11, 12 with the cutter heads 3, 4, the corresponding drive elements and pressure elements.
  • the slider 35 can also be adjusted horizontally between two end positions perpendicular to the transport direction 31. In the one end position shown in FIG. 1, the cutter head 4 is in the processing position, which processes the left side as the wood passes through.
  • the other cutter head 3 is in turn in the rest or maintenance position.
  • the slide 35 also has a stop ruler 39, which is provided on the side facing the slide 32 and has an approximately triangular support 40 in outline.
  • the stop ruler 39 carries on its longitudinal side facing the table top 18 two pressure rollers 41 and 42 which are spaced apart and which can be freely rotated about vertical axes.
  • the pressure rollers 41, 42 rest against the left side of the woods and press them firmly against the stop rulers 19 and 20.
  • the pressure rollers 41, 42 lie at the level of the cutter head 1 in the working position As a result, the timbers are guided properly in this area.
  • the slide 35 In the transport direction 31 behind the pressure rollers 41, 42 and in front of the cutter head 4, the slide 35 is provided with a pressure shoe 43, the pressure surface 44 of which runs obliquely backwards in the transport direction 31 and inclined in the transport path.
  • the pressing surface 44 like the pressing surface 34, lies in a vertical plane.
  • a belt drive 45 serves as the drive, the belt 46 of which is guided via a pulley 47 on the vertical spindle 12 and via a pulley 48 on a drive shaft 49 of a motor (not shown in more detail).
  • the belt 46 and the corresponding spindles or shafts are arranged on the slide 35 so that the spindle 11 can be brought into contact with the one strand of the belt 46.
  • the cutter heads 1 and 2 of the slide 32 can also be rotated.
  • the cutter heads can also be driven by any other suitable drive, for example by a gear motor.
  • the horizontal spindles 13 to 16 are each mounted on a slide 50 and 51.
  • these sliders are not shown in FIG. 1, whereas, conversely, the sliders 32 and 35 have not been shown in FIG. 2 for reasons of clarity.
  • the sliders 50 and 51 can be adjusted vertically between two end positions perpendicular to the transport direction 31.
  • the slider 50 with the cutter heads 5 and 6 and the horizontal spindles 13, 14 is in its lower end position, so that the cutter head 5 assumes its processing position in which it processes the top of the continuous wood.
  • the lower cutter head 6 assumes its rest or maintenance position, in which it in turn, for example, exchanged or its knives can be exchanged or reworked.
  • a belt drive, a gear motor and the like can in turn be used to drive the cutter heads or spindles.
  • the drive and pressure elements are in turn provided on the slide 50.
  • slides 32 and 35 these parts can be precisely adjusted to one another as long as one cutter head is in the working position and processes the continuous wood.
  • a pressure shoe 52 on the slide 50, the pressure surface 53 of which extends obliquely downwards and forwards in the transport direction 31. With this pressing surface 53, the pressure shoe 52 rests on the upper side of the continuous wood and holds it firmly on the table top 18.
  • the pressure shoe 52 is provided on the side of the slide 50 facing the slides 32, 35.
  • the slide 50 has a pressure rail 54 which can be pivoted about a horizontal axis 55 lying perpendicular to the transport direction 31. If the cutter head 5 is in its working position shown in FIG. 2, then the pressure rail 54 is pivoted downward into the horizontal position so that it rests on the top of the continuous wood and this is firmly against the table top 18 during processing by the cutter heads presses.
  • the pressure rail 54 can be pivoted, for example, by a pneumatic cylinder (not shown), which is also arranged on the slide 50. In the working position, the pressure rail 54 is located in the transport direction 31 directly behind the cutter head 5 and in the area above the subsequent cutter head 8. The height of the pressure rail 54 can expediently be adjusted.
  • the slide 51 is gem. Fig. 2 in its upper End position in which the cutter head 8 assumes its working position and processes the continuous wood on the underside.
  • the slide 51 is essentially of the same design as the slide 50 and also has a pressure rail 56 which is provided on the side of the slide 51 facing the slide 50 and is also pivotable about a horizontal axis. Since the slide 51 is in its upper end position, the pressure rail 56 is pivoted into its vertical rest position and is not effective. It lies in the rest position in the area above the pressure rail 54. Since the two pressure rails 54 and 56 arranged on the mutually facing sides of the sliders 50, 51 can each be pivoted about the horizontal axes running perpendicular to the transport direction 31, the sliders 50, 51 relatively close to each other on the moulder. If the slides 50, 51 are adjusted, the pressure rails 54, 56 are pivoted into the vertical rest position beforehand, so that the slides can be moved past one another.
  • the slide 51 On the side facing away from the slide 50, the slide 51 is provided with a further pressure rail 57, which is shorter than the pressure rail 56 and is located directly behind the cutter head 7 in the transport direction 31.
  • the pressure rail 57 can only be adjusted in the vertical direction, but cannot be pivoted about a horizontal axis.
  • the spindles 9 and 10 or 11 and 12 on the slides 32 and 35 lie in a common vertical plane lying perpendicular to the transport direction 31.
  • the spindles 13, 14 and 15, 16 of the slide 50 and 51 are slightly offset from each other in the transport direction 31.
  • the spindles 13 and 16 are each closer to the slide 35 than that other spindles 14 and 15 on the two sliders 50 and 51 (Fig. 1).
  • the wood transported by the moulder after dressing on its underside by the dressing tool 30 is first by the cutter head 1 on its right side, then by the Knife head 4 on its left side, processed by the knife head 5 on the top and finally by the knife head 8 on the bottom.
  • the stop ruler 39 which is located opposite the cutter head 1, can be adjusted transversely to the transport direction 31 in order to adapt to wood of different widths, so that the woods are pressed securely against the stop rulers 19, 20 by the pressure rollers 41, 42.
  • the pressure rollers 41, 42 and the pressure shoe 43 are only a short distance behind one another, so that the woods are reliably guided on this side during processing. Even in the area of the horizontal spindles, the timbers are guided correctly by the closely spaced elements 52, 54.
  • the feed rollers 22 ensure that the woods are pressed against the table top 18 and thereby reliably guided.
  • the carrier part 27 has moved into its right end position, so that the right-hand feed roller 22 of the carrier part in FIG. 2 lies in the area above the cutter head 8 in the working position. As a result, the distance between this feed roller 22 and that in transport direction 31 preceding pressure rail 54 low, so that the woods are properly guided and transported in this area.
  • the slides 32, 35, 50 and 51 can be adjusted in the (not shown in detail) guides of the moulder perfectly in the horizontal or vertical direction transversely to the transport direction 31.
  • the slides are moved to two end positions, as described above, so that the respective cutter heads can be precisely positioned.
  • the slides 32, 35, 50 and 51 are adjusted by positioning motors, which enable the slides to be adjusted in a targeted manner. As a result, an exact adaptation to wood of different thicknesses and heights is possible in a simple manner.
  • the knives of the knife heads 1 and 4 are to be reworked, then only the slides 32 and 35 need to be shifted so that the other knife heads 2 and 3 come into the working position. Then you can continue working with the moulder while the knives are being reworked on the knife heads 1 and 4 which are in the rest position.
  • the stop rulers 36 and 39 are folded up.
  • the stop ruler 36 can be folded down. It is then opposite the cutter head 3. In this position, the wood passing through the molding machine is first processed on the left side and then on the right side.
  • the slides 50 and 51 can also be adjusted in the same way, so that the respective other cutter heads 6 and 7 get into the working position.
  • the woods are first processed with the cutter head 6 on the underside and then with the cutter head 7 on the top.
  • the slides 32, 35, 50 and 51 can be adjusted independently of one another, so that the wood can be processed in a wide variety of ways with the various cutter heads. For example, it is possible to move the cutter head 1 and cutter head 3 into the working position, so that the woods are only processed on the right-hand side when they pass through both cutter heads. It is also possible, for example, to adjust the slides 50, 51 in such a way that the woods are processed only on the top or only on the bottom by the corresponding cutter heads. In this way, there is a large number of setting options.
  • the moulder can also have further vertically and / or horizontally adjustable slides with corresponding cutter heads, so that the possible uses of this moulder can be expanded considerably.
  • the support part 27, which is adjustable in the transport direction, ensures that the woods can also be reliably gripped and transported by the feed rollers 22 in the region of the slide 51. If the cutter head 7 is brought into its working position, the carrier part 27 in FIG. 2 is first shifted to the left into the position indicated by dashed lines. Then the cutter head 7 can be easily adjusted into its working position. If the associated slides 32 and 35 or 50 and 51 each occupy the same position, the corresponding pressure rails or stop rulers, which lie in the path of movement of the respective other slider, are of course folded up.
