Definitions

  • the present invention relates to an edge-grinding machine for glass sheets, particularly for vehicle windows, with a conveyor track for feeding and carrying away of the discs into and out of a processing station, on-coming - cash stops for determining the wheel position in the machining site, as well as a turntable for receiving and Rotating the discs during grinding using a grinding tool.
  • a machine of this type is known from EP-A 0 126 038.
  • the conveyor track of this known machine has conveyor belts running in the conveying direction, each of which transports a glass pane to the processing point, where the glass pane is guided against stops which determine its position.
  • the stops are permanently mounted below the conveyor belts and can be pneumatically raised to an effective position to position a glass pane, and which are in an ineffective, lowered position when a finished glass pane is to be transported out of the processing point.
  • This known embodiment has several disadvantages. Every new adjustment of the stops has to be done by hand, in that the stops have to be dismantled, moved to the new location, reassembled and precisely adjusted.
  • a continuous adjustment of the stops in the longitudinal direction of the conveyor track is only possible if the conveyor track is constructed in the manner mentioned from longitudinal conveyor belts, between which the stops can be raised at any point in the longitudinal direction.
  • a completely arbitrary arrangement of the stops across the conveyor track is not possible because of the continuous conveyor belts.
  • An object of the present invention is now to simplify and improve the conveyor track for transporting the glass panes and the adjustability of the stops. This goal is achieved in that the stops, the turntable and the grinding tool are arranged on a cantilever extending across the conveyor track.
  • the conveyor track is thus now free of additional elements, in particular of stops, and it can be designed in a particularly simple and appropriate manner, preferably as a roller conveyor.
  • the stops can be set in any direction regardless of the conveyor track.
  • the setting of the stops significantly and improve that at least one incrementally adjustable by a motor stop cheibenposition for determining the S is present.
  • at least two stops in this manner can be set, wherein a longitudinal stop for determining the wheel position in the conveying direction of the conveyor track may be designed as a stop bar, while a transverse stop can be attached chleifkopf on a S, may be what already sent incrementally by means of a motor and thus can also take over the stop function for determining the transverse position of the disk on the conveyor track or in the processing point.
  • Another object of the invention is to create optimal positioning conditions for the glass pane, in that the stops are such that a three-point contact of the glass pane always takes place. The disc always reaches a clearly defined stop position.
  • Another object of the invention is to achieve a correspondingly precise control of the movement of the turntable or of the glass pane adhering to it.
  • This goal is achieved in that the turntable is driven by a gear mechanism, the play of which is eliminated by a preload torque, for example an air motor.
  • This torque should be selected higher than any torque acting on the glass pane in any direction so that any play in the gearbox never comes into play.
  • the machine shown has a machine table 2 on a machine bed 1.
  • This machine table is designed as a roller conveyor, each roller 3 being driven by a central drive 6 via belts 7 and 8 via the gears 4 and belts 5 shown in FIG. 5.
  • FIGS. 3 and 5 there are two shorter rollers 3 'in the middle of the machine table in such a way that a gap 9 is formed on one side in the roller conveyor, into which parts one in FIGS 5 schematically illustrated grinding head 10 can enter laterally.
  • FIGS. 1 and 3 several, for example three, similar machines can be arranged one behind the other, i.e. Glass panes 11 can be fed via a conveyor device 120 and then via the roller tracks 3 of the machines arranged one behind the other in the direction of the arrows in FIG.
  • a stop bar 12 Kunststoffsanschlag than L, which determines the position of the glass sheets in the travel direction or in the conveying direction of the roller tracks, and a transverse stop 13 which is arranged on the grinding stone 10 and determines the position of the glass sheet transversely to the roller conveyor or the conveying direction thereof.
  • the stop bar 12 is attached to a carrier 14 which can be incrementally adjusted by means of a spindle 15 and a motor 16 along a guide 17 in the longitudinal direction or conveying direction of the roller conveyor 3. As shown in FIGS.
  • the carriers 14 and thus the stop bars 12 of the three machines are coupled by means of linkages 14 ', so that adjustment means 15, 16 are only to be provided in one machine.
  • the stop bar 12 which is parallel to the rollers 3 and 3 ', is connected to a vertical guide 12a, and can be moved from the inactive inactive position shown in FIG. 6 to a lower one by means of a pneumatic cylinder 12b , effective position can be moved directly over the rollers 3.
  • Fig. 6 also shows the stop pin 13, which at the lower end of the grinding head 10 with the grinding wheel 18 is firmly attached.
  • a slide 10 'with the grinding head 10 with its drive motor 19 can, as shown in FIG. 2, be moved incrementally by means of a spindle 20 and a motor 21 along a cantilever 22 projecting transversely over the roller conveyor 3, with a stroke of, for example, 600 mm.
  • the guide 17 is attached to the outer, free end of the boom 22.
  • a vertical-axis turntable 23 is mounted, which can be driven incrementally via a gear 24 by means of a motor 25.
  • the motor 25 and the gear 24 are designed, for example, in such a way that the turntable 23 is rotated by one thousandth of a degree for each step of the motor 25.
  • the turntable 23 is provided with a pneumatic suction device for receiving glass panes 11.
  • a certain torque can be continuously exerted on the turntable 23 in a certain direction by means of a pneumatic motor 28 via a toothed belt 26 and a transmission 27. This torque must be greater than any torque exerted on the glass plate 11 by the cutting force of the grinding wheel 18, so that the toothings of the gear 24 always remain in the same way without play. There can therefore be no errors due to backlash in the gear 24.
  • lifting bars 29 are arranged symmetrically with respect to the turntable 23 between rollers 3 and 3 ', which are supported on a supporting frame 30, which by means of a pneumatic cylinder 31 from the rest position shown in which the lifting bars 29 are somewhat below the upper horizontal Tangent plane to the rollers 3 are raised to raise a glass disc resting on the rollers 3 against the turntable 23.
  • the lifting strips 29 are also of different lengths in order to penetrate the grinding head 10 to allow gene across the roller conveyor in the immediate vicinity of the turntable 23 (Fig. 6). This makes it possible to process glass panes of very different sizes. The smallest panes of 0.3 x 0.3 m and the largest panes of 1.2 m wide and 0.8 m long can be machined in relation to the direction in which the glass panes run.
  • raw glass panes 11 according to FIG. 3 are fed in at certain intervals, these intervals corresponding almost exactly to the mutual distance of the three machines arranged in series.
  • the longitudinal stops 12 of the three machines are lowered simultaneously and position the three supplied glass sheets in the longitudinal direction.
  • the front edge of the stop bars 12 against which the panes run or the edges of these disks that hit the bar are designed in such a way that a two-point support is created such that the panes rest against the bars 12 in a clearly defined position.
  • the grinding head 10 is in a somewhat retracted position, that is to say in a position shifted somewhat upwards relative to the position according to FIG. 3, so that the glass panes can enter freely next to the stops 13.
  • the grinding heads 10 or the transverse stops 13 are now advanced into a very specific stop position by means of the motors 21 and spindles 20 according to a common program, whereby the position of the glass panes transversely to the roller tracks are clearly determined.
  • the disks must be fed in such a way that the cross stops 13 run against them and the disks in all cases have to shift something so that the position is clearly determined by stops.
  • the transverse stop 13 lies at a suitable distance outside the edge of the grinding wheel 18, so that the grinding wheel cannot come into contact with the edge of the glass wheel after the glass plates have been positioned.
  • the lifting strips 29 (FIG. 4) are raised by means of the cylinder 31, with the glass panes being raised against the turntable 23.
  • the disks are then sucked in and the lifting strips 29 are lowered again.
  • the machines are now ready to process the edges of the pane. This processing is carried out according to a common program, according to which the grinding wheel is now advanced to the edge of the glass pane, whereupon the rotation of the turntable also begins step by step according to a specific program.
  • the speed of rotation of the turntable can be programmed in such a way that the same feed or cutting performance is always achieved. This type of processing is known per se and is not the subject of the invention.
  • the grinding head is removed and the vacuum in the rotary plate 23 is released, so that the glass panes fall onto the respective roller conveyor. However, they can also be returned to the roller conveyor by means of the support strips 29. Since the longitudinal stops 12 have already been raised at the beginning of the processing, the finished processed panes are now removed, and new glass panes to be processed can be supplied practically simultaneously or shortly thereafter. The work cycle described above then begins again.
  • the stops 12 and 13 (FIGS. 1 + 3) can be set incrementally at any time in a very simple manner according to a specific program or after arbitrary inputs by means of the motors 16 or 21.
  • the control of the stop 13 is always carried out according to a predetermined program, while the stop 12 always remains in the fixed position during the processing of certain glass panes. In both cases, however, it is possible to enter corrections during the processing of certain panes, which may become necessary.
  • the attacks are thus not only in no K onflikt with the roller track, but their respective readjustment or correction can be made in an ampster way by electronic control.
  • the lifting strips 29 could be omitted if the turntable for receiving or dispensing glass panes is axially adjustable.
  • the longitudinal stops 12 can have a specific design on their front edge, which acts as a stop, which is adapted to a specific glass pane, the stop strips 12 being easily replaceably fastened to their support. It is also of particular advantage here that all machine parts are easily accessible from the side, in particular the external fastening of the longitudinal stop to its support 14. However, specially shaped stop parts or individual stop cams that can be placed on the stop bar 12 could also be provided.
