Definitions

  • the invention relates to a roller for processing web or band-shaped flat material, consisting of a cylindrical hollow body made of metal, in the cylinder wall of which a helical medium channel through which a heating or cooling medium can flow is provided and whose end faces are closed by a line passage for the flow medium comprising end closures are.
  • rollers are used as heating or cooling rollers for processing sheet or strip-shaped flat material, such as textiles, paper, cardboard, plastic or metal foils, around these materials in the course of their manufacture or processing or further treatment through their contact engagement with the cylinder wall to heat or cool the roller.
  • the web-like or band-shaped flat material is generally guided over the roller with partial wrapping around the cylinder jacket, the roller being rotatably supported and possibly driven in a suitable manner.
  • the cylindrical metal hollow body forming the roller consists of a roller core with a central bore, the medium channel through which the heating or cooling medium can flow being formed by helical channels which are cut into the surface of the roller core.
  • a helical channel for the flow medium is formed in this way.
  • the invention has for its object to provide a roller for processing - web or band-shaped flat material, which is simple to manufacture, avoids sealing problems in the region of the cylinder wall and develops a highly effective heating or cooling output.
  • this object is achieved according to the invention in that the cylinder wall is formed by a cast tube and the helical medium channel is formed by a tube coil made of a metal with a melting temperature which is significantly higher than that of the cylinder wall, and in that the tube coil is shrunk with the metal is firmly connected to the cylinder wall.
  • the high manufacturing costs of a two-part heating or cooling roller with a flow channel for the heating or cooling medium incorporated into the surface of the roller core is avoided in a simple manner in that the cylinder wall is formed by a cast tube in which the defining the helical medium channel Pipe coil as a simple prefabricated component is firmly anchored by shrinking engagement with the cast and solidified metal.
  • This firm anchoring intervention is ensured by the fact that the metal of the prefabricated pipe coil has a significantly higher melting temperature than the casting metal forming the cylinder wall, which surrounds the solid pipe coil on all sides during the casting process in the liquid state and shrinks onto the pipe coil when it cools under solidification.
  • the intimate connection of the pipe coil with the metal of the cylinder wall achieved in this way not only avoids any sealing problems in the area of the cylinder wall, but also rapid temperature control and a highly effective heating or cooling output through rapid, good heat conduction through the cylinder wall.
  • cylinder wall is formed by a centrifugally cast tube, in the wall of which the tube coil is also cast, has proven particularly advantageous.
  • the particularly fine, dense structure of the cylinder wall with very good strength properties achieved by centrifugal casting has a further favorable influence on the heat transfer through the cylinder wall and the anchoring engagement of the pipe coil, the pipe coil being used in a simple manner as a prefabricated component in the application in centrifugal casting Finding rotary form can be used and fixed.
  • all suitable metals or alloys can be used as casting metal for the cylinder wall and as metal for the prefabricated pipe coil, in which the melting temperature of the pipe coil is significantly higher than that of the casting metal, since during the casting process the pipe coil changes shape due to softening or melting of its metal is to be avoided.
  • the tube coil is made of steel or a steel alloy and the cylinder wall is made of aluminum or an aluminum alloy.
  • the melting points of steel and aluminum are so far apart that the shape changes featured manufactured steel tube coil is excluded by softening during the casting of the cylinder wall.
  • a pipe coil made of steel has such a high strength that the shrinking forces occurring when the cast aluminum solidifies can be safely absorbed by the pipe coil. It is advisable to cool the casting at ambient temperature in order to ensure that the casting metal is shrunk slowly and therefore evenly onto the steel tube coil in the interest of an intimate anchoring.
  • one of the two end closures forms a bearing base which closes the associated end face of the hollow body, while the other end closure is designed as a bearing and connecting base with the line passage for the flow medium, which comprises two coaxial flow channels, each having a flexible one Connection line are connected to the inflow or the return flow end of the tube coil in an area immediately adjacent to the bearing and connecting base.
  • the heating or cooling roller shown in the drawing for processing sheet or strip-shaped flat material, such as paper or plastic film sheets consists of a cylindrical hollow body 1 made of metal, in the example shown aluminum, with a cylinder wall 2 and two end closures 3, 4, each closing one of the two end faces of the cylinder wall.
  • the cylinder wall 2 is formed by a centrifugal casting tube, in the wall of which a pipe coil 5 made of metal with a higher melting point than the metal of the cylinder wall 2, such as steel, is also cast in and is thereby firmly connected to the cylinder wall.
  • the coil 5 forms a helical channel through which a heating or cooling medium flows when the roller is operating. All flow media in liquid, steam or gas form suitable for this purpose can be considered as heating or cooling medium. Since the pipe coil 5 cast into the cylinder wall 2 does not cause any sealing problems, it is in particular also possible to connect the roll to a pipe with a cooling gas e.g. to connect a freezer that works on methine.
  • the thickness of the cylinder wall 2 is, as is usual with centrifugally cast pipes, only a fraction of the pipe diameter, for example 1/6, which favors rapid temperature control due to the small masses involved.
  • the end closure 3 comprises a bearing base 6 which closes the associated end face of the hollow body 1 and is welded to the cylinder wall 2.
  • the end closure 3 further comprises a bearing pin 8 which is screwed to the bearing base 6 by means of a screw flange 9.
  • the other end closure 4 is designed as a bearing and connecting base with a line passage for the flow medium, which comprises two coaxial flow channels 10 and 11.
  • One of the two flow channels 10, 11, in the selected example the flow channel 10 is in flow connection with the inflow end 12 and, accordingly, the other flow channel 11 with the return flow end 13 of the pipe coil 5.
  • the inflow end 12 and the return flow end 13 of the coil 5 lie close together in the cylinder wall 2 in the end region of the cylinder wall 2 adjoining the end closure 4 bordering area, the coil 5 is provided with a reversing bend 14.
  • the pipe coil extends helically in the cylinder wall 2, as is illustrated by the pipe axis 15 shown in broken lines.
  • the end closure 4 comprises an outer base ring 16 which is welded to the cylinder wall 2, and an outer cover 17 and an inner cover 18.
  • the outer cover 17 is screwed to the base ring 16 by means of a screw flange 19 and has an outer bearing pin 20 for rotatably supporting the roller in a bearing schematically indicated at 21.
  • the bearing journal 20 is connected to a known rotary inlet 22 for the flow medium, which comprises a medium inflow 23 and a medium outflow 24.
  • the rotary lead-in 22 has a threaded pin 25 to which the bearing pin 20 is screwed.
  • the two coaxial flow channels 10 and 11 extend through the bearing journal 20.
  • the flow channel 10 is formed by an inner tube 26 which is fixed at one end in the rotary inlet 22 and is in flow connection with the medium inflow 23 thereof.
  • the other end of the inner tube 26 is fixed in a central insert part 27 of the inner cover 18, which engages in a central opening of the outer cover 17.
  • the flow channel 11 is formed by an annular space 28, which surrounds the inner tube 26 and is formed in the interior of the journal 20 continues at one end in a corresponding annular space of the connecting pin 25 of the rotary inlet 22 and in this is in flow connection with the medium drain 24 of the rotary inlet 22 via an enlarged annular space 29.
  • the annular space 11 opens out via an enlarged annular space 30 into an axial channel 31 extending through the inner cover 18.
  • the end regions of the two flows opening into the inner cover 18 Channels 10 and 11 are connected via a flexible connecting line 32, 33 to the inflow end 12 and the return flow end 13 of the coil 5, for example screwed.
  • the flexible connecting line 32 connects a short axial channel 34 in the extension of a central bore 35, in which the inner tube 26 is fixed, to the inner medium channel 10.
  • the flexible connecting line 33 is in turn connected to the axial through channel 31 of the inner cover 18.
  • the inner cover 18 also has an edge flange 36, with which it is screwed in a sealing manner with the interposition of an annular seal 37 with the inside of the outer ring 17. Furthermore, the central insert part 27 of the inner ring 18 in the bore 35 is provided with an annular seal 38, which is in sealing engagement with the outer circumference of the inner tube 26 and seals this against the flow channel 11.
