Definitions

  • the present invention relates to rotary ironers for ironing in particular substantially rectangular pieces of cloth, such as bed linen and tablecloths, 5 and wherein the rotary ironer comprises at least one essentially horizontally arranged and rotatably journalled ironing roller that has two ends, and wherein the ironing roller is provided with an ironing pan that encloses a part of the circumference of the ironing roller essentially throughout the entire length of the ironing roller, and wherein the ironing roller and the ironing pan 10 thus form a supply side, whereby by means of the ironing roller the piece of cloth is pulled into the abutment area between the ironing roller and the ironing pan, and a discharge side opposite the supply side, wherein the piece of cloth is yet again pushed out of the ironing roller.
  • Conventional rotary ironers of this kind very often comprise a very rigid and inflexible ironing pan that is configured with very large material thicknesses. These rotary ironers are most often heated by means of condensing steam, the ironing pan being able to easily resist the super-atmospheric pressure of the steam to be supplied to the ironing pan in order to obtain the desired
  • ironing pans are taught in eg EP patent No. 573,402, DE patent application No. 19757756 and US patent No. 3118240, wherein the ironing pans are configured of two flexible, substantially rectangular steel plates that are spaced apart, except that they are closely joined along their periphery and in a number of spot joints within the periphery, whereby they combine to form a hollow flexible ironing pan, and wherein - on the ironing pan at each of the ends of the ironing roller - one ore more supply tubes is/are configured that are integral with the ironing pan for supplying steam to the cavity of the ironing pan.
  • integral supply tubes being at each position on the ironing pan configured as separate tubular members in that, on the integral supply tubes, at each position there are configured separate coupling flanges/stubs for coupling of steam supply tubes onto the integral supply tubes.
  • integral steam supply tubes being at each position longitudinally of the ironing roller and thus at each position on the ironing pan separated from each other rather than constituting a welded supply tube that extends along the entire ironing pan, it is thus ensured that no power influences are transmitted as a consequence of thermal expansions and contractions via these tubes like to the ironing pan. Simultaneously it is obtained that the overall volume of the tubular system can be reduced considerably, in particular due to the prior art relief zones welded onto the ironing pan being redundant, thereby, other things being equal, providing a higher degree of safety, the safety in connection with pressurized containers being often calculated as the overall volume of the container multiplied by the pressure to which the container is exposed.
  • integral steam supply tubes in particular centrally on the ironing pan seen in relation to the axis of rotation of the ironing roller.
  • such supply tubes are configured exclusively at each end of the ironing pan, and in this context the overall container volume of the ironing pan is advantageously further reduced by the coupling flanges/stubs being configured at each their end of the ironing roller and hence the ironing pan.
  • the steel plate that, during use of the rotary ironer, faces towards the ironing roller is configured from black steel or ferritic steel, which, other things being equal, entails that a lower steam pressure can be applied than was necessary in the event that stainless steel was used, as it is known in particular from DE patent application No. 19757756 and EP patent No. 573402; black steel or ferritic steel usually having a conductivity that is up to four times as high as stainless steel.
  • both the steel plates that form the ironing pan are further advantageously constituted of black steel or ferritic steel, whereby undesired deformations of the ironing pan due to differences in the thermal expansion coefficient of the plates are thus avoided.
  • the steel plate that faces towards the rotary ironer during use is constituted of a plate with a material thickness of between 2 and 6 mm. And preferably between 3 and 5 mm. And the steel plate that faces away from the rotary ironer during use has a material thickness of between 0.75 and 2 mm, and preferably between 1 and 1.5 mm.
  • the ironing pan may further comprise one or more discharge pipes for collecting and discharging condensed steam from the ironing pan interior; by configuring such discharge pipes at the bottom of the ironing pan in the normal use position thereof such discharge pipes will be located on a bent and thus relatively rigid area of the ironing pan, which means that high demands are not made to reducing the effect by which the discharge pipes influence the ironing pan.
  • the integral supply pipes are in flow communication and attached to the ironing pan at each of the corners of the rectangular steel plates, whereby steam is supplied to the rotary ironer at the uppermost edges thereof, and at each of the ends of the ironing pan seen relative to the normal use position. This ensures good distribution of heat on the surface of the ironing pan.
  • two of the integral supply pipes located at least at the one end of the ironing pan advantageously extend from the ironing pan and slangtingly there below, thereby entailing a further reduction of the impact exerted by the integral supply pipes on the ironing pan.
  • a further reduction of the influence of the integral supply pipes on the ironing pan is furthermore achieved provided the two integral supply pipes at the one end of the rotary ironer are provided with each their coupling stub/flange for releasable coupling of steam supply pipes to the integral supply pipes.
  • the integral supply pipes at the one end of the ironing pan are releasably coupled to one or more steam supply pipes that extend longitudinally of the ironing pan and towards the opposite end thereof.
  • the ironing pan can easily be coupled to an existing steam supply plant at the one end of the rotary ironer.
  • Figure 1 is a sketch showing a rotary ironer according to the present invention, seen in a front view;
  • Figure 2 is a sketch in the form of a sectional view along the line A-A shown in Figure 1.
  • FIG 3 is a sketch showing the ironing pan shown in Figures 1 and 2 with supply pipes and discharge pipes welded thereto.
  • the ironing pan is shown in unfolded state and seen from the outside.
  • FIG 4 is a sketch showing the ironing pan according to Figure 3, wherein the welding spots are shown.
  • FIG 5 is a sectional view through the ironing pan shown in Figure 4.
  • FIG. 1 is a sketch showing an ironing pan seen in a front view, wherein the ironing pan comprises frame parts 1, wherein is configured an ironing roller 2 that can be caused by a not shown motor, by means of the gear 18, to rotate about the axles 4.
  • an ironing pan 5 is provided in a conventional manner, on which supply pipes 6 are mounted at each end of the ironing pan 5.
  • the two shown supply pipes 6 are not connected to each other; rather they are separate and each provided with each their mounting flange 8 for mounting of further steam supply pipes 7, only a few of which are shown.
  • FIG. 2 shows a sectional view of the ironing roller 2 shown in Figure 1 with ironing pan 5, seen along the line A-A according to Figure 1.
  • the ironing roller 2 has a direction of revolution as illustrated by the arrow C around the centre D formed by the axles 4 shown in Figure 1, whereby the ironing roller 2 and the ironing pan 5 form a feed slot 9 for the introduction of pieces of cloth between the ironing roller 2 and the ironing pan 5, following which the piece of cloth is transported between the ironing roller 2 and the ironing pan towards the outlet opening 10.
  • FIG 2 shows that the supply pipes 6 shown in Figure 1 are provided both at the inlet 9 and the outlet 10, such that pressurized steam is supplied to the ironing pan 5 via these supply pipes 6 that are yet again, via the shown coupling flanges 8 or stubs, coupled to not shown steam supply pipes.
  • the ironing pan 5 forms a yoke in which the ironing roller 2 can rest, and in a commonly known manner the ironing pan is suspended between the inlet 9 and the outlet 10 that thus forms the upper areas of the ironing pan in the normal use position thereof.
  • Figure 2 shows that in the ironing pan 5 a discharge pipe 11 is configured, as is shown in detail in Figure 3. This discharge pipe 11 is, as shown, provided with a separate coupling flange or stub 12.
  • FIG 3 shows the ironing pan 5 shown in Figure 1 and 2 in unfolded and plane state for the sake of overview.
  • the ironing pan 5 is, as will appear, constituted of two essentially rectangular plates, joined by welding, as will appear in further detail from Figure 4, but wherein the plate has an inlet edge 9a and an outlet edge 10a and an edge 14 at each end of the ironing pan plate 5.
  • the discharge pipe 11 is configured in a common conventional manner with pipe bends 13 that are configured with a view to reducing the forces by which the discharge pipe 11 influences the ironing pan 5 and that may occur in case of diverse expansions and contractions due to the heat expansion coefficients of the materials.
  • the discharge pipe can be configured as two separate pipes with separate coupling flanges or stubs, as is provided in accordance with the invention in connection with the supply pipes 6.
  • this alternative is not put to use due to the ironing pan being, in the area where the discharge pipe 11 is provided, configured to be relatively rigid due to the shape of the ironing pan.
  • Figure 4 shows the ironing pan 5 shown in Figure 3 in the same unfolded state, but without the supply pipes 6 and discharge pipes 11 shown in Figure 3.
  • the two plates are joined to each other by welding face to face in all the shown singular points 15 and at the periphery of the plates, which is constituted by the two end edges 14 and the inlet edge 9a and the outlet edge 10a in combination.
  • Figure 4 shows the supply apertures 16 that form the passage for steam from the supply pipes 6 to the interior of the ironing pan 5 and the corresponding discharge apertures 17 that form passage from the interior of the ironing pan 5 to the discharge pipes 11.
  • Figure 5 shows a detail of the ironing pan 5 shown in Figure 4, shown in a sectional view. From here it will thus appear that the two plates, joined by welding, have mutual contact merely via the two above-mentioned welded areas and, between these, they are configured such that they create a flow path that allows steam to pass across the entire surface of the ironing pan from the supply openings 16 to the discharge openings 17.
  • This configuration can be performed as a pre-shaping of the one of the plates, but is preferably performed by providing a powerful hydraulic super-atmospheric pressure between the plates after they have been joined by welding.
