Definitions

  • the present invention relates to a working transverse to its direction of travel Device and its use such that when combined with conventional Grinding machines transverse to each other, connected parts of frames and frame-like Workpieces are ground in a single pass in their own longitudinal direction.
  • Such a device is known from JP-A-59-115 155.
  • Cross-sanding unit 37 Although they are pre-built Cross-sanding unit 37 provided, but since with the usual construction of frames (for example windows) the transverse friezes 32, 24 are inserted between the longitudinal friezes 27, 35 the cross friezes, even with perfect pre-grinding, would be replaced by the following Broadband smoothed again across their orientation. If you gave the frame across, i.e. with the width 27 ahead, into the machine, this problem would be eliminated (because with the Cross sanding unit would grind the longitudinal friezes, the cross friezes would follow sanded with insert-controlled broad belts), but usually allows the working width the machine does not cross the frame. Another one that is not familiar in practice The method of operation would be to close the cross-grinding unit at the outlet of the grinding machine assemble.
  • the whole frame would be sanded with the broad bands the cross frieze finally (with the same grain size) regrind at the outlet with the cross sanding belt. Because of the one pass (because of the previously mentioned restrictions regarding working width) the cross friezes lie in the longitudinal direction of the frame again between the friezes. The latter would therefore have to be mission-controlled (from one Transition transverse to longitudinal frieze to the other transition). Suitable for this however, the previously used operational control of the cross-section unit does not exist in that individual segments 40 of a continuous sanding pad 39 the cross sanding belt press on the area to be sanded.
  • the present invention now describes a device in which the frames are initially guided on a transport carpet 13 through an automatic thickness adjustment 11 measuring over the entire working width.
  • this defines the height of the transport table (depending on the workpiece thickness determined) compared to a subsequent, longitudinally movable, driven carriage 14 guided on both sides, which is equipped with a belt grinding unit 15 mounted transversely to the direction of travel.
  • the automatic setting triggers a pulse control when the workpiece leading edge passes. This controls the use of the slide by calculating the feed speed. If the cross frieze 32 is at the level of the latter, the slide starts to move and accompanies the workpiece.
  • the abrasive pad 17 on the carriage and belonging to the belt sanding unit starts to move transversely to the direction of travel. If the sensor 22 connected to the sanding pad (in front of the sanding pad in the side axis, set back in the longitudinal axis) detects the lateral outer edge 30 of the frame, it brakes (and with it the entire sanding pad) and scans the width of the longitudinal frieze at a slow speed.
  • the sanding pad When the inner edge 31 is reached, the sanding pad is set down, this accelerates, driven by a motor to a linear working speed, and presses the sanding belt 18 on the device pneumatically to the actual sanding process on the transverse frieze 32 , he brakes the cushion, stops the grinding process and the cushion returns at high speed to a position between the starting position and the front longitudinal frieze 27. At the same time, the carriage 14 also moves back to its starting position with the belt grinding unit 15.
  • the cushion in turn moves to the frieze outer edge 30, which is detected by a second sensor 23 (placed in front of the grinding cushion in the lateral and longitudinal axes); the cushion probes with the help of the sensor to the inner edge 31, where it settles on the belt 18 and grinds the second cross frieze 24.
  • the second sensor 23 detects the rear inner edge 33 of the longitudinal frieze, the cushion slows down, stops and moves back to the starting position at accelerated speed.
  • the carriage 14 also moves back to its starting position with the belt grinding unit 15. If the frame contains one or more middle friezes 36, this is ascertained with the button 12 at the inlet and an additional, similar transverse movement is triggered.
  • this device is combined with a broadband grinding machine 41 or integrated into this (the measuring device 11 can be built in front of the broadband grinding machine and serves to control both systems), the latter will initially grind the entire frame in the longitudinal direction. The device described will then regrind the cross friezes in their own direction 25 (in the case of wood: in the wood fiber direction) and achieve the desired sanding pattern.
  • the device described instead of the belt sanding unit and the sanding pad is equipped with another device for sanding (e.g. with a surface or profile sanding unit 21 that carries the sanding belt), with brushes 20, fleece or tools with a similar function, the corresponding surface-effective effects can be achieved in this way achieve that they follow the Frisians in their own longitudinal direction.
  • the device according to claim 7 also serves internal profiles 28 (such as rebates etc.) of frames.
  • the implement for example a brush with Sanding bristles, with fleece or materials with a similar effect
  • the device instead of reaching the inner edge of the rear frieze to expose (like this with surface grinding in combination with the conventional grinding machine is the case), the device remains in its end position and processed during this operation the frame advancing on the transport carpet on the inner profile of the longitudinal frieze. It only stops when the inside edge of the second cross frieze is reached.
  • two such devices a first first the cross frieze profile 32 and then the longitudinal frieze profile 35 and a second processed the other longitudinal frieze profile 27 and then the rear cross frieze profile 24
  • the entire inner profile of a frame can be processed in a single pass.
