Definitions

  • the invention concerns a rotating-drum machine for dyeing textile articles.
  • the machine in question is intended to be used advantageously in the industrial sector in order to treat with dyeing processes textile articles or garments of any kind made from a wide range of fabrics.
  • the machines for treating textile articles conventionally consist of a frame resting on the ground and supporting a containing tank inside which a treatment fluid usually consisting of water containing, mixed therewith or in solution form, various dyeing products is introduced.
  • the tank has, arranged inside it, a drum which can be operated so as to rotate by special movement means in accordance with operating steps predefined by the programmed treatment cycles.
  • the drum is equipped with a loading hatch for receiving the textile articles to undergo the dyeing treatment and with a plurality of through-holes through which the treatment fluid flows.
  • the latter is stored inside a bath provided at the bottom of the tank.
  • the dyeing treatment conventionally occurs during rotation of the drum, as a result of the continuous immersion and extraction of the articles within/from the bath. Colouring of the articles occurs in fact as a result of the mechanical action due to falling of the articles inside the rotating drum which allows uniform penetration of the treatment fluid into the fibres. This action may be assisted by the presence of vanes which are fixed to the drum and which raise the textile articles above the treatment bath and then release them when they reach the top of the drum so that they fall as a result of gravity into the said treatment bath.
  • a first drawback consists in the use of large amounts of water which is the direct result of operation using machines with high bath ratios. This in fact constitutes a problem in those countries where water is a precious commodity which must be conserved and used with great care.
  • the fluid is removed from the bottom of the tank and conveyed to an external circuit in order to be temperature-regulated by suitable heating means so that the bath reaches the temperature envisaged by the various programmed treatment cycles.
  • the dosage of numerous products required for the treatment of the garments is directly or indirectly proportional to the quantity of fluid used for the bath.
  • the quantity of fluid required by the machines known hitherto is necessarily dependent upon the quantity of fluid which forms the bath contained in the bottom of the tank.
  • the problem underlying the present invention is that of overcoming the drawbacks of the art known hitherto by providing a rotating-drum machine for dyeing textile articles, which is able to achieve a reduction in the bath ratio without adversely affecting the quality of the treatment carried out on the said articles.
  • a further object of the present invention is to provide a machine which allows operation with a particularly low bath ratio while ensuring a correct removal of the fluid from the bath by circulating means provided.
  • a further object of the present invention is to provide a machine which does not require the use of a treatment bath in which the articles are immersed in order to perform dyeing thereof.
  • a further object of the present invention is to provide a machine equipped with treatment means which are able to operate with any type of article and in particular with delicate articles while nevertheless maintaining a high quality of treatment without damaging the said articles.
  • a further object of the present invention to provide a machine equipped with a rotating drum able to avoid creating turbulence inside a storage bath provided.
  • a further object of the present invention is to provide a machine which is operationally entirely reliable.
  • 1 denotes in its entirety the rotating-drum dyeing machine forming the subject of the present invention.
  • Said machine is intended to be used for the treatment of textile articles M of any type and made of any material and in particular for carrying out dyeing treatments thereon.
  • the machine 1 is composed of a support frame 2 which rests on the ground and which supports a containing tank 3 via rigid or resiliently yielding support means 4 which are conventional per se.
  • the tank 3 has a substantially cylindrical shape and contains inside it with play 5 a rotating drum 6 which is also substantially cylindrical and has a side wall 7 which extends longitudinally along the axis Y between two end walls, i.e. a front end wall 8 and rear end wall 9, both of which are substantially disc-shaped.
  • the front wall 8 is equipped with a hatch 40 for loading the rotating drum 6 with the textile articles M to be treated.
  • a transmission shaft 10 supported by means of bearings is fixed to the rear wall 9 of the rotating drum 6 and is actuated in a controlled manner and in accordance with predefined operating steps by suitable motorized means 100 which are known per se and for this reason are not shown in detail.
  • the rotating drum 6 is preferably made of steel and it is possible to envisage fixing inside it several radial blades which are able to divide its internal volume into segments, said blades also being of a type known per se, but not envisaged in the preferred examples of embodiment shown in the accompanying figures.
  • the side surface 7 is provided with a plurality of holes 11 able to allow a treatment fluid to flow between the tank 3 and the inside of the drum 6.
  • the invention envisages the use of treatment means 50 able to keep the bath ratios at very low values.
  • These means 50 comprise nozzle means 51 which are composed of one or more nozzles, mounted on the tank, on one or both the end walls 8, 9 of the drum 6, and which emit a jet of fluid 60 inside the drum 6 which extends along the longitudinal length of the latter so as to reach the articles M distributed along the side wall 7.
  • nozzle means 51 advantageously comprising a single nozzle 18 which is located on the front wall 8 (examples in Figures 1 and 2) or the rear wall 9 (example in Figure 3), it being understood, however, that these nozzle means 51 may also envisage the use of several nozzles located on the front wall 8 or also only on the rear wall 9 with the respective jets being able to be combined, on top of each other or alongside each other, without departing from the protective scope of the present invention.
  • the nozzle 18 is arranged in a substantially axial position, mounted on the loading hatch 40 of the tank 3 arranged facing the front wall 8 of the drum 6.
  • the nozzle 18 is mounted on the distribution shaft 10 which is axially hollow so as to allow to pass through it the end part 17" of the line 17 described in greater detail below.
  • the jet of fluid 60 has a laminar form and emerges from the nozzle or from the plurality of nozzles provided, at a pressure of between 0.5 and 5 atmospheres.
  • the laminar form of the jet 60 extends in accordance with the example shown in the accompanying figures along the whole longitudinal length of the drum 6. As it leaves the nozzle 18, the jet 60 widens slightly and preferably assumes a form which, viewed in cross-section, is substantially triangular with the base of the jet 60 arranged in the region of the articles M and having a width preferably of between 5 and 30 cm.
  • This form of the jet 60 is preferred and the choice thereof takes into account the flow rate and the pressure of the treatment fluid as well as the bath ratio and the methods of treating the articles M.
  • the nozzle 18 is mounted on the loading hatch 40 so as not to extend, except by a small amount, inside the containing chamber defined by the drum 6 so as to avoid interfering with the textile articles during rotation of the said drum 6.
  • Protection means 70 consisting for example of a nozzle-covering housing fixed to the wall of the tank above the nozzle 18, may be envisaged.
  • the jet 60 is preferably directed towards the bottom part of the drum 6 (see Figures 1 and 2) so that the nozzle 18 may be more easily protected, at the top, from falling garments M by the protection means 70, but may also be directed towards the top as indicated in the example shown in Figure 3.
  • the nozzle 18 never substantially interferes with the movement of the garments M arranged inside the drum 6, and its jet spraying function, which may be in both an atomized and non-atomized form, always remains fully effective in operational terms.
  • the garments are made to adhere to the inner side surface of the drum, as a result of the action of the drum speed which is sufficient for the garments to overcome the force of gravity.
  • the protection means 70 prove to be useful, in particular when, in order to change the distribution of the garments inside the drum, pauses or reversals in the direction of rotation of the drum are envisaged, causing the garments to become detached and fall from its inner side surface.
  • the treatment means also comprise a storage bath 12 contained inside a reservoir 13 which is connected by means of a circulating system 14 to the nozzles 18 and to the tank 3 and is arranged in a position remote from the rotating drum 6 so that the bath 12 is not affected by the turbulence following rotation of the rotating drum 6.
  • the circulating system draws the treatment liquid from the bottom of the tank so as to prevent the garments from being immersed inside a pool on the bottom thereof and introduces it into the drum by means of the nozzles which distribute it in an appropriate manner.
  • the invention substantially eliminates the treatment bath inside the tank 3, which is usually used to perform dyeing treatments, and instead makes use of a storage bath 12 arranged in a position at a distance from the drum 6, which position, depending on the specific constructional solution may be chosen, for example outside the tank 3, as in the examples according to Figures 1 and 3, or inside a portion of the tank 3, as in the example according to Figure 2.
  • the circulating system 14 comprises a connecting line 15 connected, at its first end 15', to the top of the reservoir 13 and, at its second end 15", to a lower collecting portion 16 of the tank 3 for removing the fluid from the latter and introducing it inside the reservoir 13 so as to supply the bath 12 in accordance with predefined operating steps.
  • the said fluid circulating system 14 also comprises a supply line 17 connected in turn at a first end 17' to the bottom of the reservoir 13 and at a second end 17" to the nozzle 18 for drawing the fluid from the bath 12 and introducing it under pressure inside the rotating drum 6.
  • the line 17 has, arranged along it, a recirculating pump 19 able to cause the fluid to flow around the circulating system 14.
  • the reservoir 13 is formed in a bottom portion 20 of the tank 3 and into it flows all the fluid which has acted on the garments M during treatment and accumulates as a result of gravity.
  • the fluid circulating system 14 comprises in this case, using the same numbers as in the preceding example, a supply line 17 connected at a first end 17' to the bottom of the reservoir 13 and at the second end 17" to the nozzle 18 so as to draw the fluid from the bath 12 and introduce it under pressure inside the rotating drum 6.
  • the line 17 has, arranged along it, a recirculating pump 19 able to cause the fluid to flow around the circulating system 14.
  • heating means are also provided, said means acting on the storage bath 12 so as to heat it to the temperature envisaged by the various treatment cycles.
  • heating means advantageously consist of an electric resistance indicated by means of a coil 21 in the accompanying figures.
  • the said heating means may be of the steam heating type or consist of other systems which are well-known to a person skilled in the art.
  • the treatment fluid usually consists partly of water and partly of products which are mixed or in solution form inside it.
  • Supply means 23 are also envisaged for introducing the products into the reservoir 13.
  • the said supply means comprise a container body or mixer 24 for mixing treatment products P which are introduced inside it manually or automatically, removing them from special basins connected to the container body 24, and a line 5 which has, arranged along it, a pump 26 and is connected to the container body 24 and to the reservoir 13 for replenishing the bath 12 with the products P necessary for carrying out the various programmed treatment cycles.
  • the treatment fluid may assume the desired characteristics such as, for example, a given pH value, a given temperature, or a given composition, by regulating automatically using a logic control unit or also manually the storage bath 12 contained inside the reservoir 13 with the introduction of specific products or with the aid of the heating means 21.
  • the treatment means 50 also comprise a source 80 of pressurised gaseous fluid, preferably air or nitrogen, connected to the nozzle 18 (or nozzles) by means of a line 81 having, arranged along it, manual or automatic regulating means 82.
  • a source 80 of pressurised gaseous fluid preferably air or nitrogen
  • the jet emitted from the nozzle 18 will preferably consist of a combination of the treatment fluid in the liquid state and the gaseous fluid in the gaseous state.
  • This latter fluid is able to perform the dual function of supporting the treatment fluid so as to allow it to reach even the farthest positions of the side wall 7 of the drum 6 as well as limit the impact of the jet 60 of treatment fluid on the garments M in particular when the latter are of a delicate nature.
  • the treatment fluid and gaseous fluid it is possible to reduce the density of the jet 60 acting on the garments M or the number of droplets of fluid which reach, per unit of area or per unit of time, the garments M to be treated.
  • a step involving removal of the fluid from the bottom of the tank is also envisaged, so that there is no accumulated liquid with which the articles must interfere during their rotation.
  • an accumulation of liquid on the bottom of the tank would also cause an accumulation on the bottom of the drum 6.
  • This situation would mean that the articles which rotate adhering to the drum 6 would interact violently with this accumulated liquid, impairing their perfect condition.
  • the more delicate articles would thus be damaged, namely their surface would have long threads forming the so-called napped effect.
  • dyeing is performed by means of treatment cycles which envisage rotational movements of the drum 6, during which the textile articles M are made to adhere to the side surface of the drum 6 by the centrifugal force imparted to them by the rotation of the drum 6.
  • the laminar jet of fluid 60 can be distributed over the entire longitudinal length of the drum 6, reaching the garments distributed inside it and suitably treating them without being interrupted by the falling garments.
  • the articles are made to adhere by the centrifugal force on the internal surface of the drum with the correct compression able to avoid subjecting the articles on the surface to wear, in particular avoiding the formation of zones exposed to varying degrees of treatment opposite the holes in the drum and the smooth parts.
  • the same centrifugal force is able to impart to the articles a sufficient degree of softness and looseness or, on the other hand, optimum compaction in order to allow correct penetration of the cleaning or dyeing liquid.
  • rotation of the drum is correlated to the pressure of the fluid jet so as to allow correct penetration, depending on the type of garment treated, of the dyeing fluid into the fibre of the textile articles.
  • this centrifugal acceleration is designed to ensure an optimum speed of penetration of the liquid also depending on the type of fabric to be treated.
  • the dyeing method according to the present invention allows dyeing of the textile articles without mechanical action and keeping them immobile on the side wall of the drum with a suitable compressive force.
  • the present invention goes against the common knowledge of the sector which instead envisaged a mechanical beating action in order to allow uniform distribution of the dye within the fibres.
