Definitions

  • the invention relates to a stop device for machines for frontal machining of wood, in particular window wood, such as tenoning and slotting machines, with a cutting device for the woods, which is connected upstream in the machining direction of the tenoning spindle and with a roller table, which the workpieces on the cutting device and Tang drive spindle passes.
  • a known attachment device of this type consists of a measuring stick, which is attached to the roller table and carries a hand-displaceable stop, which has a display device which lies opposite a scale on the measuring stick. With such a device, the distance between the stop and the cutting device can therefore be adjusted.
  • the cutting device is usually a saw.
  • the invention is therefore based on the object to provide a stop device of the type mentioned, with which these disadvantages are avoided and which ensures that the lengths required in each case can be set quickly and easily without difficulty.
  • a fixed guide extending perpendicular to the direction of movement of the roller table is provided in the workflow in front of the cutting device for a slidable along the guide, overlapping the roller table in the starting position and with its abutment surface in the direction of movement of the roller table , the stop being driven by means of a toothed belt reinforced by tension cord inserts and being fixable relative to the guide in various installation positions predetermined by an electronic control.
  • the quickly repeatable and easily electronically controllable setting is made possible by the use of the toothed belt as a transmission element, because this enables a slip-free transmission of the drive of the stop over long distances.
  • the toothed belt also enables a relatively high movement speed of the stop and relatively short start-up and braking times.
  • the arrangement according to the invention has the advantage that it works practically without play, so that it is not necessary to let the drive run backwards in order to reach a certain stopping point.
  • drives of a different kind, such as chain drives which would also have the disadvantage that chain wear would occur during operation due to the wear that occurred, so that exact length adjustments would not be possible.
  • the device according to the invention can be controlled particularly easily and precisely electronically if the toothed belt is driven by a stepper motor.
  • a good embodiment for such a stepper motor can be that it makes 400 steps per revolution and moves at a maximum of 600 revolutions per minute. It is particularly advantageous here if a reduction is provided between the stepper motor and the toothed belt drive, so that at least one step of the stepper motor corresponds to a movement of the stop on the guide of approximately 0.1 mm.
  • stepper motor makes it possible to provide exact length movements of the stop on the guide in the manner described, the movement by 0.1 mm at the same time the accuracy of the device, i. corresponds to the maximum tolerance.
  • stepper motor also has the advantage that the special movement characteristics of a stepper motor can be exploited when starting up and braking, which consists in the fact that a relatively rapid start-up gradually changes into the actual movement phase and braking takes place in the same way. This ensures that both the start-up and the braking phase are kept relatively small and that an exact stopping takes place at the predetermined point.
  • the reduction of the rotational speeds of the stepping motor for the belt drive is advantageously also made of toothed belt drives, wherein advantageously two successively switched belt drives are used to determine the angle of curvature of the toothed belt around the driven sprocket not be too small to let e
  • Such an arrangement has the advantage that l uch the translation between the stepper motor and the toothed belt drive for the stop is almost free of play and slip-free. It has proven to be useful if four steps of the stepper motor correspond to the movement of 0.1 mm of the stop.
  • the lengths that the stop has to travel through are expediently given to the stepping motor by a computing device, a microprocessor or the like in the form of step numbers. In this way it is achieved that the stepper motor is automatically stopped after the number of predetermined steps has expired.
  • this computer or microprocessor is designed in such a way that it specifies steps with increasing or decreasing frequency in the initial and braking phases, so that starting and braking can be carried out in an optimal manner.
  • a zero point setting can be provided, which can consist of an inductive transmitter, which is assigned to the movable stop in the region of the guide.
  • This measurement The encoder switches on the stepper motor via the computer or the microprocessor in such a way that the stop is brought to a stop in a position corresponding to a certain maximum induction with respect to the transmitter. If this position is exceeded, the microprocessor controls the stepper motor in the opposite direction until the zero position is reached by repeated oscillations.
  • the transmitter can be adjusted along the guide of the stop, since in this way the zero position and thus the length assignment can be changed depending on the assignment of the device according to the invention to different machines.
  • the device according to the invention is therefore able to set the stop precisely and without slip to the specified lengths.
  • this only applies to the drive itself.
  • the invention further provides for the stop to be fixed in the respective setting position. This can be done by a coupling in the drive of the toothed belt, which fixes the drive shaft for the toothed belt in relation to a stationary housing.
  • a magnetic coupling of various types, in particular a magnetic tooth coupling, can be used for this purpose Find use.
  • the forces acting on the stop act on the free end of the toothed belt corresponding to the length of the wood, so that the forces are absorbed elastically in the expansion area of the toothed belt.
  • the stop is fixed on its guide. This can be done by means of a brake, a clamp or the like, which acts on the guide itself.
  • the fixing can be brought about in that the stop carries at least one clamping jaw assigned to a rail, which is pressed against the rail. This can be done by a pneumatic cylinder or the like.
  • the guides are designed as round rails which are overlapped by the guide pieces of the stop and the clamping jaws. Guides of this type are particularly easy to manufacture precisely.
  • the brakes are actuated at a time interval after the stepping motor has been stopped.
  • the time is accordingly Lichen distance the brakes released before starting the stepper motor. This takes place in the millisecond range.
  • a stationary cover which runs parallel to the guides and which carries the rear end of the window wood and is run over by the stop, can be connected to the roller table.
  • the arrangement according to the invention can be applied to simple tenoning and slotting machines, but it is particularly advantageous if it is applied to known combination machines in which at least one tenoning spindle is assigned to at least one milling spindle for longitudinal profiling, the directions of advance of the workpieces relative to the tools of these spindles run at right angles to each other, so that the wood with pins and slots can be transferred to the milling spindles at a right angle.
  • the cutting device 4 consists of a driven saw blade 8 and a drive motor 7.
  • a stop device 9 is arranged, which consists of a stationary guide 10, which extends perpendicular to the direction of movement of the roller table 5, for a stop 11 which can be moved along the guide, 1 on the left in FIG. 1, the stop in its extreme retracted end position with solid lines and on the right in FIG. 1 in its most advanced end position in dashed lines.
  • the stop is driven by means of a toothed belt 12 reinforced by tension cord inserts, which is attached with its upper run to a cross member 13 or the like of the stop.
  • the toothed belt 12 runs over three pinions 14a, 14b and 14c, of which in the illustrated embodiment the pinion 14c on the right in FIG. 1 is driven.
  • the drive of the pinion 14c is electronically controlled in the manner described below, so that the stop 11 can be fixed quickly and securely in various setting positions.
  • the guide 10 consists of two round rails 15 (cf. also FIG. 2) which are overlapped by guide pieces 16 of the stop (cf. FIG. 2).
  • the stop consists of a horizontal plate 17, to which a plate 18 arranged perpendicularly thereto is connected, which has the actual abutment or stop surface 19 (FIG. 1) for the workpieces.
  • the stop 11 overlaps the roller table 5 with a section 20 in its initial position shown in FIG. 1, whereby known clamping devices for the workpiece are provided on the roller table, which allow the workpiece to be known to be clamped on the roller table 5 in the setting specified by the respective position of the stop.
  • roller table 5 At the roller table 5 is a stationary, parallel to the guide rails 15 extending cover 21, which supports the rear end of the workpiece to be machined in the starting position. This cover 21 is also overlapped or passed over by the section 20 of the stop 11.
  • cover 21 a roller conveyor or the like, not shown here, may be provided.
  • an inductive transducer is indicated in FIG. 1, which is assigned to the movable stop 11 in the region of the guide 10.
  • This sensor is used for zero point adjustment and switches on the drive of the toothed belt 12, which will be described in such a way that the stop 11 is brought to a stop in a position corresponding to a certain maximum induction relative to the sensor 22. This position may be achieved by swinging back and forth.
  • the transducer 22 can in turn be adjustable along the guide 10 of the stop 11, for which purpose a separate guide 23 can optionally be provided.
  • FIG. 3 is the partial section III-III of FIG. 2 on an enlarged scale and shows the drive of the drive pinion 14c in detail.
  • the associated FIG. 4 is the view IV-IV according to FIG. 3.
  • the toothed belt 12 is driven by a stepper motor 24, a reduction being provided between the stepper motor 24 and the toothed belt drive, which also consists of two toothed belt drives 25 and 26 in the exemplary embodiment shown.
  • the toothed belt drive 25 has an output pinion 26 which is arranged in a fixed position with the pinion 14c on a common shaft 27 and is driven by a drive pinion 29 via a toothed belt 28. This in turn sits with an output pinion 30 on a common shaft 31, which is driven by a drive pinion 33 on the shaft of the stepping motor 24 via a toothed belt 32.
  • FIG. 3 a first embodiment for fixing the toothed belt is provided in FIG. 3.
  • a magnetic tooth coupling which has a sliding sleeve 34 or the like in a stationary housing 35, which overlaps a ring gear or a square 36 which is arranged in the extension of the shaft 27 and is fixedly connected to it.
  • the components described last are indicated by dashed lines in FIG. 3.
  • one of the guide pieces 16 is designed as at least one of the intact guide rails 15, clamping jaws 37 and 38 encompassing on both sides, which are acted upon by a pneumatic cylinder 39 with an intermediate coupling 40.
  • the pneumatic cylinder 39 is in a time stood after the shutdown of the stepping motor 24 in the clamping device and correspondingly acted upon starting before starting the stepping motor in the release direction of the clamping jaws 37 and 38.
  • FIG. 6 shows a somewhat modified embodiment of the arrangement according to FIG. 5, part 41 of the guide pieces 16 being designed to be stationary and a pivotable clamping jaw 42 is provided which presses on one side against the guide rail 15 and against the stationary part 41 .
  • the clamping jaw 42 is also acted upon by a double-acting pneumatic cylinder 43, the piston rod 44 of which is connected to the free end of the clamping jaw 42 by a threaded connection 45.
  • the jaw 42 is pivotable about an axis 46 extending parallel to the guide rail 15.
  • Fig. 7 shows the step frequency-time diagram for the stepper motor 24.
  • the stepper motor has a particularly advantageous movement characteristic, which consists in the fact that a relatively rapid start in phase A gradually changes into the actual movement phase B and that the braking takes place in the same way in the braking phase C. In this way, both the start-up and the braking phases A and C are kept relatively small and an exact stopping at the predetermined point is guaranteed.
  • the stepper motor 24 is now electronically controlled for setting the required lengths so that a certain number of steps to be performed by the stepper motor are specified by a computer or a microprocessor. This number of steps corresponding to the respective length is stored in a control unit, so that only the desired length needs to be set or keyed in on the control unit, which the control unit then converts into the required number of steps for the stepper motor. After the number of specified steps has elapsed, the stepper motor is automatically stopped by the control unit.
  • the transmitter 22 is used in the manner already described, which is arranged adjustable for the stop 11 relative to the guide 10. With maximum induction, the electronic control system finds the zero point for the stop, from which the steps of the stepper motor specified by the electronic control system count.

If, as shown in FIG. 8, cut-to-length devices 4 and tenoning spindles 3 are provided on both sides of the milling spindles 2 for longitudinal profiling and the workpiece passes through the woodworking machine in the direction of arrows 47 to 49, then the stop device 9 according to the invention is expediently left in FIG. 8 between the milling spindles 2 ngsprofilieren to L ä and the downstream cutting device 4 is arranged. In this application form, the workpiece cut to an approximate length is first guided past the cutting device 4 and the tenoning spindle 3 on the right in FIG.
  • the stop device 9 In another woodworking machine, in which a tenoning spindle 3 is provided only on one side, in which the cutting device 4 shown on the left in FIG. 8 and the associated tenoning spindle 3 are omitted, the stop device 9 according to the invention is shown in dashed lines on the right in FIG. 1 , the first cutting device 4 and the associated tenoning spindle 3 upstream. Is in this form A u s Installations- ie by means of the stop device 9 and the cutting device 4, the workpiece from the start to the accurate measurement, provided at one side with pins and slots, and then longitudinally profiled. The workpiece is then turned over and provided with the same tenoning spindle 3 in the second pass with tenons and slots.
  • the stop device according to the invention also makes it possible to save a considerable amount of work, time and storage space in the production of windows.
  • the disadvantage here is that space-consuming interim storage facilities are required and that additional work steps are required to transport to and from the interim storage facilities and to put together the respective timber for the windows.
