Definitions

  • a sheet glass forming and annealing machine of the so-called vertical draw type is supported by a gimbal mounting adjacent the uppermost portion of the machine.
  • the gimbal mount is supported by a framework which surrounds the machine and extends upwardly from the floor on which the machine base would otherwise rest.
  • This invention relates to machinery supports and more particularly to a suspended support for glass drawing machines of the vertical draw type.
  • a vertical draw sheet glass forming machine is of the order of 50 feet in height and the weight of the machine is of the order of 70 tons.
  • a plurality of pairs of rollers (usually 30 or more) which are used to draw the sheet of glass upwardly from a molten bath in order to form it into continous sheets and anneal the sheets which may then be cut off in any desired lengths.
  • machines of this type operate under extreme conditions of temperature. The lower portions of the machine operate at a very high temperature relative to the upper portions of the machine and therefore there is a temperature gradient from the bottom to the top of the machine.
  • the principal object of the present invention is to provide a suspension type of support for a vertical draw sheet glass forming machine which is effective to eliminate substantially entirely the need for realigning the position of the various roll pairs.
  • FIGURE 1 is an isometric view of a glass machine supported in accordance with the present invention
  • FIGURE 2 is a top plan view of FIGURE 1 with parts of the supporting system broken away;
  • FIGURE 3 is an exploded perspective view of the bearing portions of the support in accordance with the present invention.
  • FIGURE 4 is a view partially in section of the assembled bearing shown in FIGURE 3.
  • the objects of the present invention are achieved by supporting a vertical draw sheet glass forming machine from its top in such a manner that it is free to swing in two planes at degrees to each other.
  • a .glass making machine is schematically represented by the rectangular solid identified by the reference numeral 10.
  • brackets 12 are rigidly attached, two on the front and two on the rear surface.
  • Each bracket includes a vertically arranged jack screw 13 to compensate for machining and assembly errors.
  • FIG- URE 1 Four columns 14, three of which are shown in FIG- URE 1, extend substantially the full length of the machine from the foundation of the building to a point adjacent the upper portion of the machine. Supported on these four columns are cross members 16 which together with the columns 14 comprise a framework which forms the entire load support for the machine.
  • the heart of the present invention lies in the mode of supporting the machine at its upper end on the aforesaid framework. Still referring to FIGURE 1, a pair of boxlike structures 18 and 20 completely surround the machine 10. The brackets 12 simply overlie the upper box member 18 and thus the entire weight of the approximately 70 ton machine is transferred through the brackets 12 and the jack screws 13 to the upper box member 18.
  • FIG. 1 and 2 The joint between the two box members 18 and between the box member 20 and the general supporting framework is indicated in FIGURES 1 and 2 but the details of this mounting are shown more clearly in FIG- URES 3 and 4.
  • the upper and lower box members 18 and 20 are joined in such manner that they are free to rotate with respect to each other about an axis shown in FIGURES 1 and 2 at 22.
  • the lower box 20, on the other hand, is supported on the underlying framework in such manner that it is free to rotate with respect thereto on an axis 24 which is at right angles to the axis 22.
  • FIGURE 4 shows the load bearing joint between the upper and lower box members, the identical structure occurs between the lower box member 20 and the cross members 16.
  • load bearing joint is shown in exploded perspective in FIGURE 3 and includes upper and lower bearing blocks 30 and 32, both of which are rectangular solids and formed of hardened steel.
  • the center member 34 is also formed of hardened steel and instead of being a rectangular solid, it has curved upper and lower surfaces 34a and 34b with equal radii but lying in planes at 90 degrees to one another.
  • the bearing members are formed in order that they may be aligned on a pin member 36.
  • the elongated blocks 38 shown at the bottom of FIG- URE 3 are useful merely to be tack welded to the frame members as shown in FIGURE 4 so as to positively locate the upper and lower blocks 30 and 32.
  • the openings in the upper and middle bearing members are slightly larger than the opening in the lower bearing member in order that the pin 36 may be a tight fit in the lower member 32 but a loose fit in the members 30 and 34.
  • the machine In setting the machine up in a support in accordance with the present invention, it is lifted by a crane and positioned so that the under surface of the brackets 12 are spaced slightly above the upper surface of the box 18. The jack screws are then adjusted so that when the machine is lowered, all four jack screws touch the upper surface of the box 18 at the same time in order to have substantially equal load transfer at the four points of contact.
  • box members 18 and 20 are semielastic. By this is meant that they are specifically designed to support the weight of the machine but they nevertheless bend. The net result is that there is substantially less clearance between the ends of the boxes 18 and 20 than there is at the center location of the bearing block structure. This is an important consideration because it permits further selfaligning and force equalizing of the four brackets of the machine and compensates for geometric errors in the construction of the box members themselves.
  • Apparatus for supporting a sheet glass forming machine of the vertical draw type comprising in combination:
  • brackets rigidly secured to the outer surface of said machine in a common plane adjacent the upper end of said machine.
  • each of said bearing members comprises upper and lower plane surface blocks and an intermediate block having upper and lower cylindrical surfaces at right angles to each other.
  • each of said blocks includes a central aperture and in which said blocks are assembled on a common pin passing through said apertures.
  • Apparatus as defined by claim 2 including a jack screw in each of said brackets forming the sole load transfer means between said machine and said second box frame.
