Definitions
- the invention relates to an ironing dryer of the type in which the clothes to be ironed between a revolving iron cylinder, heated internally, and endless bands that are in contact with the outer surface of the cylinder on the major part of its circumference.
- Such ironing dryers equip usually establishments in which a a significant amount of laundry is processed daily.
- the ironing cylinder In equipped ironing dryers a rotating ironing cylinder, heated from the inside, the ironing cylinder consists of a sheet metal, the ends of which rest on rollers supported by the machine chassis. In the large machines, the cylinder diameter of ironing reaches approximately 600 mm, for a length of 4 or 5 m.
- this cylinder is usually manufactured at from a flat sheet which is bent and whose adjacent edges are finally welded according to a generator.
- the humid environment in which the ironing cylinder is permanently in poses problems of oxidation of ordinary steel usually used, especially when the machine is found in a saline environment as is the case by the sea.
- This corrosion phenomenon is all the more more difficult to control than the temperatures of heating the cylinder does not protect it, for example by means of a resin, when the machine is in operation.
- the high mass of the ironing cylinder existing machines also results in a high thermal inertia, detrimental to good adaptation of the machine to the nature of the ironed laundry.
- Document FR-A-2 698 388 describes a metallic heating cylinder, rotating around an axis horizontal, for an ironer dryer.
- This cylinder heater thin, contains elements heaters placed around an inner cylinder. A air circulation is ensured by a turbine.
- the document EP-A-0 711 861 describes a rotating metal cylinder, for a dryer bowl ironer.
- the outer envelope of the cylinder is formed alternately, in the direction circumferential, of sheets in the shape of sectors cylindrical and guide combs of a gasket elastic wound helically around the cylinder.
- the subject of the invention is precisely a ironer dryer with ironing cylinder realized in a completely original way, which allows to eliminate the aforementioned drawbacks of the machines existing and in particular to present an inertia less thermal, to deform perfectly homogeneous under the effect of temperature variations, and to have a reduced mass authorizing the use of lighter and less expensive techniques to support the cylinder.
- an ironing dryer characterized by the fact that it includes an ironing cylinder rotating in flow-turned stainless steel, made of in one piece and seamless.
- the thickness of the ironing cylinder depends in part of its outside diameter. So the reduction thickness of stainless steel sheet forming the cylinder, compared to the existing cylinder is such that the ratio between the thickness of the cylinder and its outer diameter is between 1/180 and 1/280 according to the diameter.
- the ironing cylinder has circumferential grooves on its surface exterior. This characteristic, obtained naturally by the flow forming technique if no machining is not carried out, increases the surface heat exchange, which further reduces inertia machine thermal.
- the ironing cylinder rests on curved rollers made of a non-material metallic such as a composite material comprising a glass fiber reinforcement and a resin matrix.
- each of the curved rollers is then mounted on a fixed axis via at least one ball bearing.
- Direct mounting of rollers on fixed axes reduces very significantly the size of the bearings used and, by therefore, their cost.
- the part of the chassis supporting the rollers can further be significantly lightened by compared to existing ironing dryers.
- the ironer dryer according to the invention includes a rotating ironing cylinder 10 whose original features will be described in detail thereafter.
- the ironing cylinder 10 rests on four curved rollers 12, so that its axis geometric 14 is horizontal. More specifically, each end of cylinder 10 rests on two convex rollers 12 with horizontal geometric axes are aligned two by two and parallel to the axis 14.
- the convex rollers 12 are free to rotate around their geometric axes, so that the cylinder of ironing 10 can rotate freely around itself its geometric axis 14.
- the ironer dryer also has endless belts 16 which are mounted on rollers 18, whose geometric axes are all parallel to the geometric axis 14 of the cylinder 10.
- the bands endless 16 are in contact with the outer surface of the ironing cylinder 10, over its entire length and over most of its circumference.
- rollers 18 as well as the curved rollers 12 are mounted on a chassis 20 of which only a small part appears in Figure 2. All the rollers 18 are mounted free to rotate on this chassis, except of one of them, which is rotated by a gearmotor (not shown). When this gear motor is actuated, the endless belts 16 are move in the direction of the arrows F1 in FIG. 1, by driving with them the ironing cylinder 10, as illustrated by arrow F2.
- a display 22 facilitates the introduction of pieces of ironing cloths (not shown) between the strips endless 16 and cylinder 10 so that the pieces of laundry are automatically dragged between these organs, to be ironed there.
- cylinder 10 is heated internally by heating means (not shown) generally electric or gas, and it is coated on the outside a fleece (not shown).
- the cylinder of revolving ironing 10 is made of stainless steel and obtained by flow forming, from a blank hollow cylindrical stainless steel, low long and thick.
- This manufacturing technique allows make the ironing cylinder 10 in one piece and without any soldering.
- its use allows to reduce the thickness of the cylinder to values appreciably lower than those of the ironing cylinders existing, obtained from a curved flat plate, then welded. So and only as an example, in the case of an ironing cylinder having a outer diameter of about 325 mm, we can give this cylinder a thickness of about 2.3 mm.
- the technique of flow forming used to manufacture the cylinder ironing according to the invention allows to give the report between the thickness of the cylinder and its outside diameter a value between 1/180 and 1/280 depending on the diameter.
- the production of the ironing cylinder 10 stainless steel allows the machine to be used any atmosphere and especially in the presence salty air.
- the thinning of the cylinder ironing in relation to the cylinder which equips them existing machines provide sufficient weight gain to lighten the frame 20 of the machine as well as the mechanisms including the rollers 12, at through which the cylinder rests on the frame 20.
- each of the curved rollers 12 is made of preferably a non-metallic material such as composite material comprising a fiber reinforcement glass and a matrix of epoxy resin, polyaramide, or other.
- each of the convex rollers 12 is mounted directly on a fixed axis 24, via one or two small ball bearings 26. As illustrated in Figure 2, each of the fixed axes 24 is fixed directly to part of the chassis 20 of the dryer-ironer located beyond the adjacent end of the ironing cylinder 10.
- the attachment can be do by any appropriate means, including using a nut 28, screwed onto a threaded part of the axle 24.
- curved rollers 12 no metallic to significantly reduce noise compared to existing machines and reduce significant wear of the rollers and parts of the cylinder 10 in contact with them. Reliability the machine is increased.
- the reduction in thickness of the ironing cylinder authorized by the use of flow turning technique allows the cylinder to react faster at temperature variations, when the implementation of the machine. This is explained by greater operating flexibility and, by Therefore, use the dryer ironer.
- the flow-forming technique used, in accordance with the invention, for manufacturing the cylinder iron 10 results in the formation of circumferential grooves, generally helical, on the outer surface of the cylinder. In the absence of everything subsequent machining, this characteristic results in an increase in the exchange surface between the air room and the ironing cylinder. This accentuates again the speed of reaction of the cylinder to variations of temperature.
