Definitions

  • ABSTRACT A cooling roll for a printing press having a hollow cylindrical roll body and a series of axially spaced baffle members mounted within said body for thoroughly mixing cooling fluid as it passes through the roll body and for directing the flowing fluid against the cylinder walls of the roll body.
  • Each baffle is cup shaped and is disposed within the roll body with the open end of the cup directed downstream of the fluid flow.
  • the end portion and tapered side portions of each cupshaped baffle are formed with a plurality of flutes which facilitate mixing and directing of the fluid.
  • the present invention relates generally to heat exchange rolls, and more particularly, to improved cooling rolls for use with a printing press.
  • cooling rolls can absorb heat from the moving web of paper.
  • a hot relatively inactive layer of water tends to build up along the wall of the cylinder and cool water from the inlet passes through the cylinder with very little mixing with the hot layer so that the cylinder wall is not greatly cooled.
  • the inefficiency is shown by the fact that the temperature differential of the water entering the cylinder and that leaving the cylinder is relatively small.
  • the cooling fluid is directed along narrow channels or passages adjacent the wall of the cylinder so that all water must pass in close proximity to the cylinder wall.
  • Another object is to provide a cooling roll of the above kind whereby large quantities of cooling fluid may be contained in and passed through the roll without creating an excessively warm relatively stagnant outer layer of fluid adjacent the cylinder wall. More particularly, it is an object to provide a cooling roll which may be nearly completely filled with a cooling fluid and which thoroughly mixes the fluid as it passes through the cylinder so that a steady flow of cool'fluid passes along the entire length of the cylinder wall.
  • a further object is to provide a cooling roll as characterized above which tends to bleed out air from within the cylinder as it is operated so that the cylinder fills completely with cooling fluid.
  • Still another object is to provide a cooling roll of the foregoing type which has a simple and economical design and construction.
  • FIG. 1 is a longitudinal section through the axis of a heat exchange roll embodying the present invention with two of the fluid baffles shown in section and two baffles shown unsectioned;
  • FIG. 2 is an enlarged section taken in the plane of line 2-2 in FIG. 1;
  • FIG. 3 is an exploded section taken in the plane of line 3-3 in FIG. 2 showing one of the two-part cup-shaped baffles in a disassembled condition.
  • FIG. I an illustrative cooling roll assembly 10 embodying'the present invention.
  • the assembly includes a hollow cylindrical roll body 11 suitably mounted for rotation within a frame 12.
  • an end closure head 14 having a hollow shaft extension 15 is provided at each end of the roll body 11.
  • the shaft extensions 15 each are rotatably disposed in a'bearing 16 secured in the frame 12.
  • the roll body 11 may be rotated by a suitable drive means connected with a gear 18 mounted on one of the shaft extensions 15.
  • the illustrated roll is shown rotating in a clockwise direction as viewed from the right-hand end of FIG; I.
  • a continuous web material such as' hot freshly printed paper,.may be trained about a series of such cooling rolls. Since the roll is power driven the web will proceed atj'a uniform speed through' the entire print, heating and cooling operations.
  • a continuous flow of a fluid cooling medium is supplied from a'suitable source to a roll inlet tube 20 contained within the hollow shaft extension l5'at one end'of the roll.
  • the cooling fluid passes frornthe inlet tube 20 through the roll body 11 to absorb heat from the body and then passes out an outlet tube 21 contained in the shaft extension 15 at the opposite end of the body. Since the inlet and outlet tubes 20,21 rotate with the driven'rollbody 11 and end heads 14, they are connected to supply and return lines 22, 23. respectively, through conventional rotary couplings or unions 25.
  • the fluid from the outlet pipe 23 may be directedto a refrigerating unit or other conventional heat exchange means and'then redirected to the inlet 22.
  • a series of axially spaced baffle members are mounted within the roll body for thoroughly mixing the cooling fluid as itpasses through the body and for directing the fluidlagainst the inner'cylindrical surface of the roll body.
  • four cup-shaped baffles 30 are disposed inaxially spaced relation along a threaded tie rod 31 with an open end 32 of each cup directed downstream of the fluid flow.
  • Each baffle in this case has an end portion 34 and outwardly tapered side portions 35 extending therefrom.
  • the two baffles at the outlet side of the roll body are'shown in section, whilethe two baffles at theinlet side are not sectioned.
  • a pair of threaded nuts 36 are provided-on opposite sides of each baffle.
  • a narrow cross rod 38 is secured in perpendicular relation to the tie rod 31 at each end thereof and abuts an internal shoulder 39 formed within the roll body 11.
  • the cross rods 38and tie rod 31 are thereby interposed between the roll body shoulders 39. Since the cross rods 38 are relatively narrow, they do not obstruct the fluid flow.
  • each baffle 30 are made of a two part construction with each part 30a, 30b being approximately a one-half sector of the bafile cup. As best shown in FIGS. 2 and '3, each part or sector 30a, 30b, has an axial aperture 40 which 30a, 30b, may be readily molded to the desired proportion and shape.
  • the baffles preferably are molded of a'plastic material so that the walls of the finished baffle have a slight resiliency;
  • the baffles may thereby be formed somewhat larger than the internal diameter of the roll body so that the outer edges of the baffle side portions 35 are biased into firm engagement with the inner cylindrical surface of the roll body 1 1.
  • the baffles are formedwith a plurality of flutes 41 which extend radially outward along the end portion 34 of each bafile and then longitudinally along the baffle side portion 35.
  • the flutes 41 define a series of uninterrupted passages 42 about the outer surface of the baffle back and side portions.
  • each flute 41 forms a supplement passageway 44 in the baffle side portion 35 between each of the primary passages 42.
  • the flutes 41 in the end portion 34 of the baffle create a recessed central area 45.
  • cooling fluid enters the roll body from the inlet tube (arrows 50a) and is forced out around the first baffle 30 so that the fluid is in maximum contact with the cylindrical wall of the roll body (arrows 50b).
  • the passages 42, 44 defined by the baffle flutes 41 permit the fluid to flow between the inner surface of the roll body and the outer baffle surface.
  • the flutes 41 create a sufficient resistance as to impart a lateral movement in the fluid in the direction of rotation so that the fluid in effect has a helical flow pattern (arrows 500).
  • the heat exchange roll may similarly be used as a heating roll by passing a hot fluid through the cylinder. It is also understood that although the inlet and outlet fluid tubes are disposed at 0pposite ends of the illustrated roll alternatively a counterflow roll could be used whereby the inlet and outlet are at the same end.
  • a heat exchange roll for treating webs of sheet material comprising a hollow cylindrical roll body having an outer periphery, an inner surface and closed ends, means at the ends thereof for rotatably supporting said roll body, means at one end of said body defining a fluid inlet passageway, means at the other end of said body defining a fluid outlet passageway, a single series of axially spaced, substantially identical cupshaped baffle members each having an end portion and outwardly tapered side portions mounted within the roll body, the outer edge of each baffle tapered side portion engaging said roll body inner surface, each said baffle side portion being formed with a plurality of circumferentially spaced flutes which define passageways for fluid flow between said baffle side portions and said inner body surface, said baffles being disposed with the open end of said cup directed downstream of the fluid so as to mix said fluid and repeatedly direct it against said inner surface as it passes through the length of said roll body.
  • a heat exchange roll for treating webs of sheet material comprising a hollow cylindrical roll body having an outer periphery, an inner surface and closed ends, means at the ends thereof for rotatably supporting said roll body, means at one end of said body defining a fluid inlet passageway, means at the other end of said body defining a fluid outlet passageway, a single series of axially spaced, substantially identical cupshaped baffle members each having an end portion and outwardly tapered side portions mounted within the roll body, said end portion of each baffle being formed with a plurality of radially extending flutes and said side portion of each baffle being formed with a plurality of outwardly tapered longitudinal flutes, said baffles being disposed with the open end of said cup directed downstream of the fluid so as to mix said fluid and repeatedly direct it against said inner surface as it passes through the length of said roll body.
  • the heat exchange roll of claim 1 including a rod extending axially the length of said roll body upon which said baffles are disposed, and means securing the baffles to said rod for maintaining said baffles in axially spaced relation.
  • each baffle has a two-part construction, each said baffle part being a sector of said cup and being disposed on said tie rod in partially overlapping relation with the tie rod passing through an axially disposed aperture in each part.
  • each baffle is formed with a plurality of radially extending flutes, said end flutes extending without interruption into said side flutes to define uninterrupted passages about the outer surface of said baffle, a rod extending axially the length of said roll body upon which said baffles are disposed and means securing said baffles to said rod for maintaining their axially spaced relation.
