Definitions

  • the invention relates to a woodworking machine for tapping and slitting wood, in particular window wood, in which the workpieces to be machined are guided past at least one spindle carrying the tools for tapping and slotting by means of a roller table with their respective end faces.
  • the workpiece machined on one side is applied from the roller table to a cross conveyor, which moves it in the course of a length control until the other end face of the workpiece can also be machined by further tools for punching and slotting the spindle.
  • the disadvantage of this known arrangement is that the tenoning and slitting of the second end face can only take place when the window wood to be machined is brought to tenoning and slitting in its second starting position. During this time, the rest of the machine, especially the roller table, has no function.
  • the invention is therefore based on the object to provide a woodworking machine of the type mentioned, with which the throughput can be increased significantly and in particular the individual parts of the machine can be better exploited.
  • This object is achieved in that two at least one common spindle for pounding and slotting and diametrically opposite roller tables with respect to the spindle are provided, the guides of which run parallel to one another and each have a defined end position, the roller tables in the end positions are aligned with each other and the workpieces to be machined can thus be transferred from one roller table to the other roller table, the tools of the tenoning and slot spindle on the way of the first roller table into its end position with the first end face of the workpieces clamped on the first roller table and on the way back come into engagement with the other end face of the workpieces now transferred and cut to the second roller table, and the end positions of both roller tables are reached approximately simultaneously.
  • the workpiece to be machined is clamped on the first roller table and guided with it past the tenoning and slot spindle into its end position.
  • the second roller table moves into its corresponding end position, so that in this state the window wood to be processed is brought into a position in which its second end face can be provided with pins and slots after it has been suspended.
  • the window wood is moved past the opposite side of the mortise and tenon spindle to its starting position by means of the second roller table.
  • the first roller table also returns to its original position.
  • roller tables In contrast to the end positions, the roller tables should not necessarily be aligned with each other in their starting positions, but it is advisable to provide this orientation.
  • the machine according to the invention has a particularly compact design and is particularly inexpensive due to the saving of half the spindles and their drive units.
  • the tenon and slot spindle is expediently provided with a suction hood, which faces away from the respective working intervention and is arranged to be rotatable around the tenon and slot spindle by approximately 180 °.
  • This hood is therefore expediently automatically pivoted onto the side of the tenoning and slot spindle facing away from the respective working intervention.
  • the pivoting movement of the cover expediently runs synchronously with the movement of the respective roller table, with the hood starting to rotate during an initial movement of the respective roller table in the direction of the tenon and slot spindle, and this rotary movement is completed before the workpiece Spigot and slot spindle reached so that it can be machined through the hood without interference.
  • roller tables can each be provided with a toothed rack, which engages in a start portion of the movement of the roller table in a pinion connected to the bearing of the hood, a ring gear or the like, so that the hood is pivoted when the roller table or the one lying thereon Workpiece reaches the tenoning and slot spindle.
  • hood with an arm which is connected to at least one pneumatic and / or hydraulic unit or an electromagnetic unit, these units being able to be triggered and stopped by limit switches or the like connected to the roller tables.
  • the hood is expediently provided below the tools on the journal and slot spindle, it being expedient to use roller bearings.
  • pin impact and slot spindles can be arranged one behind the other in a manner known per se, each of which is provided with pivotable hoods which can be rotated together into the position facing away from the engagement of the tools. These spindles can be brought into engagement simultaneously and / or alternately in a manner known per se. With an appropriate arrangement of the spindles, the swiveling of the hoods can also be dispensed with.
  • the workpiece transfer is facilitated between the two roller tables if a belt conveyor or belt table is arranged between the roller tables, which preferably automatically moves the workpieces to be machined from one roller table to the other.
  • Other transfer devices are possible, for example by means of a slide engaging the front ends of the workpieces.
  • the two roller tables run synchronously, ie. H. at the same time move past the spindles for mortise and tenon from their starting position into their end position and vice versa.
  • the two roller tables are arranged on a common carrier and are rigidly connected to one another by this, since in this way the synchronous operation is forced. If, however, it becomes necessary to choose a different starting position for one roller table than for the other, the two roller tables can also have a common drive that can be coupled, provided that only the respective end position in which the transfer takes place is guaranteed.
  • the arrangement according to the invention makes it possible, in particular by changing the direction of rotation of the tenoning and slot spindle (if necessary), to let the workpieces to be machined run through the machine in the opposite direction.
  • the pivotability of the hood can be omitted if at least two tenon and slot spindles with corresponding tool sets are used, the hood of one spindle on the side facing away from the first roller table and that of the other spindle on the opposite side of the spindle facing away from the second roller table or can be reversed.
  • the relatively expensive tool sets are required twice, while the pivotability of the hood provided according to the invention enables one tool set or half of the tool sets to be used. The same applies to the drives normally used if a motor is assigned to each spindle.
  • the arrangement according to the invention makes it possible, in particular, to feed the window timbers that have been finished on both end faces to one or more longitudinal profiling devices, either by feeding a first longitudinal profiling device by conveying the workpiece in the starting position and / or by reaching a second longitudinal profiling device from the transfer position.
  • This longitudinal profiling can be carried out in a separate machine. However, it is also possible to integrate the longitudinal profiling devices and thus their feed into the present machine.
  • a central spindle 1 is provided with tools for tapping and slitting wood, in particular window wood, which, including its drive (not shown), is arranged on an indicated machine frame 2.
  • two roller tables 4 and 5 are provided which lie opposite one another and whose guides 6 and 7 run parallel to one another.
  • the two roller tables 4 and 5 each have a broken end position 4a and 5a, in which the roller tables are aligned with each other, so that the workpiece 3 provided with pins and slots on one side can be transferred from the roller table 4 to the roller table 5.
  • the workpiece 3 is guided past a cross-cut saw 8 by means of the roller table 4 at the start of the processing, with which the end face of the window wood 3 facing the spindle in the starting position according to FIG. 1 is cut to a predetermined dimension.
  • the roller table 4 then moves further in the direction of arrow 9 past the tenoning spindle 1 into its end position 4a.
  • the roller table 5 performs the same movement at the same time and moves parallel to the roller table 4 in the direction of the arrow 10 into its end position 5a.
  • the workpiece 3 is optionally transferred from the roller table 4 to the roller table 5 by means of an intermediate conveyor 11, which can be a belt conveyor, whereupon both roller tables move back to their starting position contrary to the arrows 9 and 10.
  • an intermediate conveyor 11 can be a belt conveyor
  • both roller tables move back to their starting position contrary to the arrows 9 and 10.
  • the length of the window wood can be controlled at the same time, for example by means of a stop device 12.
  • the window wood is then cut to this controlled length when the roller table 5 moves back with a further cross-cut saw 13 and then its second end face is provided with pins and slots.
  • a cover 14 provided in the usual way, which serves for the suction of the chips produced but also for safety, must be rotated from the position shown in FIG. 1 by 180 ° about the vertical spindle axis, so that the tools are now exposed on the opposite side and the processing of the second face of the window wood can take place.
  • roller tables 4 and 5 then return to their starting position shown in a solid line, in which the window wood finished at its two ends can be removed from the roller table 5.
  • Fig. 2 illustrates this workflow.
  • the roller tables 4 and 5 are in their starting position according to FIG. 1.
  • the cover 14 faces away from the left roller table 4.
  • a rack 15 or 16 is connected, which engages in a ring gear 17 connected to the hood 14, which is expediently provided in the area of the bearing of the spindle 1.
  • the hood 14 is rotated clockwise, i.e. in the direction of arrow 19, the rack and the ring gear and their engagement conditions are designed so that the rotation essentially begins only when the workpiece 3 has passed the tenoning and slotting spindle 1 and has been processed by it.
  • the hood 14 can assume the position shown in (b).
  • the second toothed rack 16 connected to the roller table 5 is not in engagement with the ring gear 17 of the hood 14 or its connection to the roller table 5 is released. Corresponding couplings can be provided.
  • the workpiece 3 can be transferred from the roller table 4 to the roller table 5, that is to say in the direction of the arrow 20, in the manner described, whereupon the toothed rack 16 is then brought into engagement with the ring gear 17 or is coupled again to the roller table 5.
  • the transfer can be carried out by the belt conveyor 11, cf. Fig. 1, or by a slider 21 or the like., The latter moves in the direction of arrow 22 and shifts the workpiece 3 to the right in (b).
  • the workpiece 3 is transferred to the roller table 5 according to (c) and then assumes the position according to (d).
  • the covering hood is rotated into the position according to (d), so that now the side of the tools of the spindle 1 facing the second roller table 5 before machining of the second end face of the window wood can be freely used.
  • the roller tables 4 and 5 then return to their starting position according to (e), which corresponds to that according to FIG.
  • the workpiece 3 In the starting position (e), the workpiece 3 can be conveyed out in the direction of the arrow 25 and a new workpiece 26 can be applied to the roller table 4.
  • Fig. 3 is approximately the section 111/111 of FIG. 1 in a modified embodiment.
  • the roller tables 4 and 5 simultaneously reach their end positions according to FIG. 2 (b), the starting positions and their reaching being able to differ from one another: however, it is expedient if the roller tables 4 and 5 Run synchronously and thus also reach their starting positions according to FIGS. 2 (a) and 2 (b) simultaneously and in accordance with the position.
  • Fig. 3 shows a simple solution to this problem, wherein, as shown schematically in Fig. 3, the two roller tables 4 and 5 have a rigid connection 27, which forces both a synchronous run and the same end positions.
  • the arrangement according to FIG. 3 also has the advantage that only a single drive is required for both roller tables.
  • connection 27 expediently runs as shown below the spindle 1 and its drive assembly 28.
  • FIG. 3 also shows an embodiment of the hood 14 covering the tools 29 and the spindle 1, which is rotatably supported in the area of the drive assembly 28 by at least one roller bearing 30 about its vertical axis.
  • the toothed ring 17 can be arranged on the outer ring of the roller bearing 30.
  • two spindles 31 and 32 are provided, which can be moved in the direction of the double arrow 33 in a manner known per se.
  • the hoods 34 and 35 of these spindles do not need to be rotated because, according to the embodiment there, the spindle 31 only serves to machine the first end face and the spindle 32 only serves to machine the second end face of the workpiece 3.
  • the two roller tables 4 and 5 can also be rigidly connected to one another in the embodiment according to FIG. 4.
  • two longitudinal profiling units 36 and 37 are indicated, the longitudinal profiling spindles of which are denoted by 38 and 39. It is possible either to hand over the workpiece in the direction of arrow 40 to the longitudinal profiling unit 36 after completion of the two end faces of the workpiece 3, or to convey the workpiece to the longitudinal profiling unit 37 in the direction of arrow 41 after completion of only one end face.
  • the longitudinal profiling units 37 and 38 according to FIG. 4 can also be applied to all other embodiments of the tenoning and slitting device according to the invention.
  • Fig. 6 shows a schematic representation of an embodiment of the drive of the hood 14, wherein, as already described, the hood 14 is provided with a ring gear 17, in which a driven pinion 50 engages.
  • Fig. 7 shows an embodiment of the drive of the hood 14 which is shown in Fig. 2, because there the ring gear 17 is acted upon by the rack 16 which can be coupled to one of the roller tables and the hood 14 is rotated accordingly.
  • Fig. 8 shows an embodiment in which the hood 14 is also provided with a ring gear 17, but which is acted upon by a toothed belt 51, wherein the toothed belt 51 can also be driven by a pinion or the like. As shown, the toothed belt 51 is guided over rollers 52 and 53, which enable the pinion 54 to be interposed.
  • FIG. 9 shows an embodiment in which the hood 14 is connected to an arm 55, on which electrical, pneumatic and / or hydraulic units 56 and 57 can engage in order to close the hood 14 relative to the spindle 1 in the direction of the double arrow 58 rotate.
