Definitions

  • ABSTRACT 52 us. c1 165/89, 432/60, 432/228, Apparatus for effecting coolant fl fl in w i- 432/236 432/246 rections, through the hollow interior of a rotatably [51] Int. Cl C2ld 9/00 mounted conveyor yp ll- A o lant supply or with- [58] Field f S ar h 165/89; 432/236, 60, 228 drawal tube is inserted through one of the open ends of the central core of the roll, and depending upon the [56] References Cit d function of the tube, the open ends serve as coolant UNITED STATES PATENTS exits or entrances, respectively.
  • This invention relates to rotatable rolls that are subjected to high temperatures and more particularly to apparatus for effecting internal fluid cooling of such rolls.
  • the present invention may be used in conjunction with conveyor rolls of the type used for transporting workpieces, such as glass, ceramic or metals through high temperature ovens.
  • the invention is particularly applicable for use in cooling the large rolls commonly used in glass processing apparatus such as annealing or tempering ovens for conveying the product sheets therethrough.
  • Such rolls may be eight to ten feet in length, are very heavy and are subjected to extremely high operating temperatures.
  • Rolls of this type typically comprise steel cores on which are assembled a plurality of asbestos washers; the washers being highly compressed and held in their compressed condition on the steel core. The compressive force on the asbestos washers creates an internal gripping force of the washers on the steel core and as a result the asbestos rotates with the core to carry the glass along.
  • the present invention is directed to apparatus for internally cooling a rotatable roll having a hollow core wherein the cooling fluid is caused to flow in two streams either toward or away from a point within the hollow core. Such flow patterns tend to minimize the heating effects of the coolant which have made the through one of the open ends to the interior of the core.
  • cooling fluid By connecting an air pump or vacuum pump to the other end of the tube, cooling fluid is supplied to or withdrawn, respectively, from the core.
  • cooling fluid When cooling fluid is pumped into the core through the tube, it flows out of the core in two streams; one through each of the open ends of the core.
  • a vacuum is applied to the other end of the tube cooling fluid, typically all is withdrawn from the core and is replaced by cooling air drawn into the core through each of the open ends.
  • FIG. 1 is a side view partially in section of a roll in accordance with the present invention
  • FIG. 2 is a section taken on the lines 2-2 of FIG. 1;
  • FIG. 3 is an enlarged view of a portion of FIG. 1;
  • FIG. 4 is a section taken on the lines 44 of FIG. 3;
  • FIG. 5 is a schematic showing of one operating embodiment of the invention.
  • FIG. 6 is a schematic showing of a second operating embodiment of the invention.
  • a rotatable roll 10 having an elongated hollow metal core 12 including oppositely spaced open ends 14, 16 is shown mounted for rotation in bearing structures 18.
  • the hollow core 12 is comprised of a large cylindrical center portion 13 and spindle extensions 15 attached to and extending from each end of the center portion 13 for engaging the bearing structures 18.
  • the core 12 carries on its outer surface a glass contacting covering comprised of asbestos washers 20 which are held axially in compression by suitable means 22 as is conventional.
  • Extending through one of the open ends 14 of the core 12 is a hollow tube 24 having a diameter less than that of the interior of the core to define an annular passage 26 therebetween, as best shown in FIG. 2. This passage, as will be subsequently further described, may serve as a coolant outlet or inlet depending on the mode of operation of the-system.
  • the end 25 of the tube 24 extending into the interior of the core 12 is open to effect fluid communication therebetween.
  • the other of the open ends 16 of the core 12 is shown including a threaded plug 28 having an orifice 30 therethrough.
  • the plug 28 is screwed into mating threads 32 in the interior of the core 12.
  • the cross-sectional area of the orifice 30 is equal to the cross-sectional area of the annular passage 26 defined in the end 14 of the core 12 through which the hollow tube 24 is inserted. If a more precisely uniform flow is desired throughout the core interior the cross-sectional area of the annular passage 26 must be somewhat greater than the cross-sectional area of the orifice 30 to allow for the greater frictional flow resistance in the annular passage 26.
  • FIGS. 5 and 6 schematically illustrate two operating embodiments utilizing the invention.
  • the end of the hollow tube 24 extending out of the core 12 is coupled to a conventional source of cooling fluid 34 which may be a fan, air pump, or a water pump, or the like.
  • the coolant fluid is continuously pumped into the interior of the core 12 through the open end 25 of the tube 24.
  • the open end 25 is preferably located at the longitudinal center of the core 12 so that maximum cooling is effected at the normally hotter center of the roll 10.
  • the air exiting from the tube 24 into the core interior then follows two flow paths to exit from the core 12. A portion passes through the core and out through the orifice 30, and a portion passes through the annular passage 26 and out the open end 14. As pointed out above if the cross-sectional areas of the orifice 30 and the annular passage 26 are equal, an equal volume of cooling fluid will pass through each side of the roll.
  • the embodiment shown in FIG. 6 uses a vacuum pump or the like 36 in place of the air pump previously described.
  • the vacuum pump 36 draws coolant from the interior of the core 12 through the hollow tube 24.
  • coolant fluid which is typically atmospheric air is drawn into the core through the annular passage 26 and the orifice 30.
  • Both of the described embodiments achieve a balanced cooling effect within the roll not heretofore obtainable with the one-way flow cooling techniques previously used.
  • An internally fluid cooled rotatable roll comprisa. an elongated hollow cylindrical core having oppositely spaced open ends;
  • a hollow tube having a smaller diameter than the interior of said core and extending through one of said open ends thereof into the interior of said core where it is disposed in concentric spaced relationship therewith to define an annular passage therebetween, said tube being in fluid communication with the interior of said core;
  • means for circulating cooling fluid through said core comprising means for flowing all of the cooling fluid admitted to the interior of said core through said hollow tube, and means for flowing substantially equal amounts of the cooling fluid admitted to the interior of said core through each of said oppositely spaced open ends, said meansfor flowing a substantially equal amount of the cooling fluid through said open end through which said tube extends comprising said annular passage and said means for flowing a substantially equal amount of the cooling fluid through the other of said open ends comprises the opening in said other open end, the cross-sectional area of said annular passage being greater than the cross-sectional areaof said opening in said other open end.
  • the opening in said other open end comprises a plug, having an orifice of a predetermined size therethrough, disposed in said other open end.
