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 stop 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 stationary guide extending perpendicular to the direction of movement of the roller table for a stop displaceable along the guide, overlapping the roller table in the starting position and with its abutment surface in a plane parallel to the direction of movement of the roller table is provided, the stop being driven by means of a toothed belt reinforced by tension cord inserts and being fixable relative to the guide in various setting 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 run the drive backwards 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 longitudinal 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. H. 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 speeds of the stepper motor for the toothed belt drive also advantageously consists of toothed belt drives.
  • toothed belt drives expediently two ge in succession Switched belt drives are used to prevent the angle of curvature of the toothed belt around the output pinion from becoming too small.
  • Such an arrangement has the advantage that 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 specified 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 area of the guide.
  • This transmitter 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 specific 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.
  • 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 In order to ensure that the stop actually reaches the predetermined stopping point, the brakes, whether in the form of the clutch or the clamping jaws, are actuated at a time interval after the stepping motor has been stopped. When starting, the brakes are released at the appropriate time interval before starting the stepper motor. This takes place in the millisecond range.
  • a stationary cover that runs parallel to the guides can connect to the roller table. which carries the rear end of the window wood and is run over by the stop.
  • the z. B. is known from DE-A-28 08 276, equipped with the electronically controlled stop device according to one of claims 1 to 25.
  • the z. B. is known from DE-B-21 38 137, equipped with the electronically controlled stop device according to one of claims 1 to 25.
  • a method for the production of windows in series production according to the preamble of claim 28 is provided, which is to be attributed to the general state of the art, in which cutting to length using the electronically controlled stop device according to one of claims 1 to 25 the window frames are made.

  • 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 displaced along the guide, the stop in its extreme retracted end position on the left in FIG. 1 with solid lines and on the right in Fig. 1 in its most advanced end position is shown 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 the pinion 14c on the right in FIG. 1 is driven in the exemplary embodiment shown.
  • the drive of the pinion 14c is electronically controlled in the manner described below, so that the stop 11 can be fixed quickly and safely in various setting positions.
  • the guide 10 consists of two round rails 15 (see also FIG. 2) which are overlapped by guide pieces 16 of the stop (see 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.

  • a stationary cover 21 which runs parallel to the guide rails 15 and 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.
  • the roller table 5 moves in the direction of the arrow 6 towards the cutting device 4 or the tenon and slot spindle 3, the workpiece is taken away from the roller table and leaves the cover 21 in order to further support cantilevered workpieces Cover 21 or a roller conveyor (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 111-111 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 a drive 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. 5 Another embodiment is shown in FIG. 5. It one of the guide pieces 16 is formed here as at least one of the two guide rails 15, clamping jaws 37 and 38 encompassing on both sides, which are acted upon by a pneumatic cylinder 39 with an interposed clutch 40.
  • the pneumatic cylinder 39 is actuated in the clamping direction at a time interval after the stepping motor 24 has come to a standstill, and is accordingly acted upon in the direction of release of the clamping jaws 37 and 38 when the stepping motor is started before the stepping motor is started.
  • 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 .

  • 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-up 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 specified 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.

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.
