Definitions

  • the invention relates to a grinding device for grinding a cylindrical or spherical surface of a roller, in particular a roller of a paper machine, according to the preamble of claim 1.
  • a grinding device of the type mentioned at the outset is known, for example, from CH-PS 668 212.
  • This device is relatively complicated and, accordingly, its use is very complex since it requires a special support and an adjustable copying template which is designed as a guideway and corresponds to the desired value of the surface shape.
  • the object of the invention is to provide a grinding device of the type mentioned at the outset, which has a simple structure and can be used easily.
  • the object is achieved according to the invention by the characterizing features of claim 1. Due to the fact that the grinding device uses the scraping device assigned to a roller as a carrier and possibly as a copying template, the additional attachment of a carrier and possibly a copying template is unnecessary.
  • the grinding device is accordingly simple and inexpensive and can also be used particularly quickly and easily. This advantage is particularly important when a damaged roller has to be revised. The quick and easy use of the grinding device thus also reduces the downtimes of a production plant.
  • Claim 2 describes a particularly simple solution.
  • a configuration according to claim 3 is particularly expedient, as a result of which not only the stability of the support is improved, but also the possibility arises of being able to arrange the grinding device on both sides of the frame.
  • the grinder can be guided along the roller by hand.
  • a configuration according to claim 4 is particularly advantageous.
  • the arrangement of a clutch can prevent the grinding device from running without the drive being switched on. As a result, the grinding in of grooves when the frame is stationary can be prevented.
  • An embodiment of the grinding device according to claim 6 is also advantageous, since the reciprocal coupling of the grinding device to the frame makes it possible to use the Grinding device is increased.
  • the contact roller can be rigidly mounted, in particular when a roller with a cylindrical surface is to be ground.
  • a configuration according to claim 8 is particularly advantageous, which enables the contact roller to adapt to the contour of the surface of the roller, so that, for example, cambered rollers can also be ground.
  • a particularly advantageous embodiment describes claim 9.
  • the grinding accuracy can be improved by a further development according to claim 10, since the pressure of the contact roller is then constant at all angular positions of the contact roller.
  • a further development according to claim 11 is particularly advantageous, which enables the grinding device to be automatically and precisely adjusted.
  • tensioning the grinding belt such as tensioning rollers and the like.
  • An embodiment according to claim 12 is particularly advantageous and simple, as a result of which a symmetrical structure of the belt grinding device is favored.
  • the belt tensioning device can be formed by a mechanical spring device.
  • a particularly advantageous embodiment of the grinding device is described in claim 13, which enables subtle control of the grinding device so that even rolls with non-cylindrical surfaces over the entire length with the same permanent contact pressure can be ground.
  • the result is a grinding device that can be adjusted to a wide variety of grinding conditions, so that grinding is possible with the highest accuracy.
  • the design of the grinding device according to claim 14 is particularly expedient, as it prevents the grinding member from becoming jammed on the roller and thus preventing faulty grinding marks.
  • Figure 1 is attached to a roller
  • FIG. 1 shows the grinder of Figure 1 in
  • FIG 3 shows the frame of the grinder
  • Figure 4 shows the frame of the grinder in
  • FIG. 5 shows the frame of the grinding device with an additional securing device in section VV of FIG. 6; 6 shows the safety device according to
  • Figure 7 shows the grinding device of Figure 1 in horizontal section.
  • FIGS 1 and 2 show the overall view of a grinding device, which is arranged on a scraping device 2 of a roller 4, for example the roller of a paper machine.
  • the grinding device contains a frame 6 with rollers 8 which are placed on a scraper 10 of the scraper device 2, the scraper device 2 being shown in the state pivoted away from the roller 4.
  • the frame 6 contains a holder 12 with a support roller 14 which is supported laterally on the carrier 16 of the scraping device 2.
  • the holder 12 has an upper arm 20 and a lower arm 22 which are attached to the frame 6 transversely to the plane of the rollers 8.
  • Each arm 20, 22 is provided with a double clamping member 24, which is fixed to the arm 20, 22 by means of a clamping screw 26.
  • a rod 28, which is arranged transversely to the arms, is fastened to the clamping member and also fixed by means of clamping screws 30.
  • the support roller 14 is mounted, the plane of which extends transversely to the plane of the rollers 8.
  • the rod 28 can be adjusted both in its position on the arms 20, 22 and in its height position.
  • the arrangement of the holder 12 is such that the rod 28 is arranged halfway along the length of the frame 6 between the rollers 8.
  • this holder enables the grinding device 18 can alternately be fastened on the end faces 32, 34 of the frame 6.
  • the grinding device 18 is constructed essentially mirror-inverted with respect to the horizontal plane 36, so that by turning the grinding device, the associated mounting plate 38 can optionally be attached to one of the two end faces 32, 34 of the frame 6.
  • FIGS. 3 and 4 show details of the drive of the rollers 8 of the frame 6.
  • the frame contains a drive motor 40 which drives a drive wheel 46 for a toothed belt 48 via a gear 42 and a clutch 44.
  • the latter is guided via gears 50 which are fastened to shafts 52 on which the rollers 8 are arranged.
  • FIGS. 5 and 6 show an additional securing device 54 for securing the grinding device on the scraping device 2.
  • the scraper 10 of the scraping device 2 is first replaced by an L-shaped rail 56 in the scraping device 2.
  • the rollers 8 run on the rail 56.
  • the securing device 54 contains locking rollers 58 which are assigned to the rollers 8 and can be pivoted in against the inside 60 of the L-shaped rail 56.
  • the securing rollers 58 are fastened to a pivot axis 62, which in turn is pivotably mounted in arms 64 on the frame 6.
  • a lever 66 is attached to the pivot axis 62 and is connected to a threaded spindle 70 via a coupling member 68.
  • FIGS. 1, 2 and 7 show the grinding device 18 in the form of a belt grinding device.
  • the grinding belt 76 is guided over a floating contact roller 78, which is guided by adjacent stationary guide rollers 80, 82 and a drive roller 86 driven by a drive motor 84.
  • the drive motor 84 is arranged on a carriage 88, which is arranged in a housing 92 containing the floating bearing 90 of the contact roller 78.
  • a belt tensioning device 94 which interacts with the slide 88 of the drive motor 84 and thereby prestresses the drive roller 86 against the contact roller 78, serves to pretension the grinding belt.
  • the belt tensioning device 94 has a piston / cylinder unit 96 which is connected to a fluid device 102 via lines 98, 100.
  • the floating bearing 90 of the contact roller 78 contains longitudinal guides 104, 106 arranged in the housing 92 for an axis 108 on which the contact roller 78 is rotatably mounted.
  • the longitudinal guides 104, 106 run perpendicular to the surface to be machined, ie radially to the roller 4.
  • the axis 108 is resiliently supported on piston / cylinder units 110, 112.
  • the pressure chambers of the piston / cylinder units are connected to one another via connecting lines 114, 116.
  • the piston / cylinder units 110, 112 are also connected to the fluid device 102 via lines 118, 120.
  • the piston / cylinder units 110, 112 also serve to feed the contact roller against the surface to be machined, that is to say the roller 4.
  • a straightening device 122 serves to align the contact roller when the contact roller 78 is set and placed on the surface to be machined by one-sided placement and to avoid grinding the roller 4.
  • the straightening device 122 contains setscrews 124 (only one of which is shown) arranged on both sides of the contact roller 78 with a wear-resistant contact surface 126 which is a few tooth-millimeters in relation to the working point of the grinding belt is reset.
  • the threaded pin 124 is fastened on a protective cover 128 for the floating bearing 90, which in turn is connected to the axis 108 of the contact roller 78. If the contact roller 78 is delivered unevenly, one of the two setscrews 124 comes into contact with the roller 4 and brings the contact roller 78 into the position essentially aligned with respect to the roller.
  • the grinding device is controlled via the fluid device 102, which is preferably designed as a compressed air device, in a manner not shown in such a way that the grinding belt 76 is first given a certain pretensioning force in the piston / cylinder unit 96.
  • the contact roller 78 is supported via the axis 108 on the corresponding piston / cylinder units 110, 112, in which the necessary counter pressure is built up. If the contact roller 78 is advanced with the aid of the piston / cylinder units 110, 112 against the surface to be processed, ie the roller 4, the piston / cylinder unit 96 is retracted to the extent that the belt tension that has been set remains the same.
  • the guide rollers 80, 82 ensure the stabilization of the sanding belt on the contact roller 78, in particular also when the contact roller 78 assumes an angular position deviating from the basic position due to the contour of the surfaces to be machined due to the floating position 90 . Due to the floating bearing 90, the contact roller 78 can follow the contour of a surface to be ground. This makes it possible to regrind an existing surface, in particular to repair it, without special measures.
  • the fluid device 102 ensures that even when the grinding device is guided in a straight line, the contact roller contact pressure, which for example follows a cambered contour of the surface to be machined, is always kept constant.
