Definitions

  • the present invention relates to a machine for treating fabrics in a bath, particularly for dyeing garments, according to the characteristics set out in the preamble to the main claim.
  • Background art The invention is applicable particularly but not exclusively to the T eld of garment-dyeing machines, in which there are known machines which comprise a drum in which the garments to be treated are disposed and which can be driven in axial rotation inside a washing chamber to which a dye bath is admitted and recirculated.
  • the outer wall of the drum advantageously has holes so as not to obstruct the inward and outward flow of the bath through the drum.
  • the bath is also continuously withdrawn from the washing chamber and reintroduced thereto, after being regenerated.
  • a first object of the invention is to provide a machine with lower energy consumption.
  • a second object of the invention is provide a machine in which the contact between the bath and the fabric is more effective, particularly during the garment-dyeing treatments. This problem is solved and these objects are achieved by the present invention by means of a machine for treating fabrics in a bath, formed in accordance with the appended claims.
  • FIG. 1 is a schematic view showing, in longitudinal section, a first embodiment of a machine for treating fabrics in a bath, formed in accordance with the present invention
  • Figure 2 is a schematic view showing the machine of Figure 1 in cross-section
  • FIG. 3 is a view similar to Figure 2 showing a second embodiment of the machine according to the invention
  • - Figure 4 is a schematic view showing a detail of a variant of the machines of Figures 1 and 3 in longitudinal section.
  • the machine 1 is arranged for dyeing garments and comprises a substantially cylindrical rotary drum 2, rotatable about a longitudinal axis X by drive means of known type, generally indicated 3.
  • the rotary drum 2 defines an outer wall 4 and a loading compartment 5 inside the drum 2 in which the garments to be treated are disposed. Moreover, the drum 2 is supported axially by a tubular element 6 extending longitudinally through the loading compartment 5, and is provided with a pair of doors 2a which can be opened from the exterior for access to the loading compartment 5.
  • the drum 2 and the drive means 3 are enclosed by an outer casing la in which means for recirculating the bath as well as means for its regeneration by heating and the addition of chemical substances necessary for dyeing (which means are of conventional type and not shown in the appended drawings) are also arranged.
  • the means for recirculating the bath comprise a supply duct 7 and an outlet duct 8 through which the bath is admitted to the rotary drum 2 and withdrawn therefrom, respectively.
  • the outer wall 4 is closed from the exterior in a leaktight manner to prevent the inward or outward flow of the bath through the wall 4.
  • the wall 4 does not have the holes which are normally provided in the rotary drums of conventional machines, and the dye bath is admitted to and withdrawn from the drum 2 directly through the ducts 7 and 8, respectively.
  • a plurality of paddles, all indicated 9, for stirring the bath, extend radially from the outer wall 4 towards the interior of the loading compartment 5.
  • the paddles 9 are symmetrical with respect to the rotation axis X, are hollow internally, and are advantageously shaped with triangular profiles with rounded vertices. —
  • auxiliary ducts 13 are in communication with corresponding auxiliary ducts 13 provided for balancing the rotary drum 2 during the spinning stage.
  • a plurality of chambers 10 are also formed in the rotary drum 2; all of the chambers 10 extend along adjacent circumferential arcs around the loading compartment 5 and extend longitudinally along the entire rotary drum 2.
  • the chambers 10 have profiles with radial cross- sections all of which are tapered in the same direction from a first end 10a as far as a second, opposite end 10b.
  • Each chamber 10 is preferably formed in a manner such that its first end 10a of larger cross-section is positioned in the region of the base of a respective paddle 9 and is separated therefrom.
  • Each chamber 10 is also separated from the loading compartment 5 by means of a perforated plate 12 and is closed on the opposite side by the outer wall 4 of the drum 2.
  • the perforated plate 12 advantageously permits flow communication between the compartment 5 and the chamber 10.
  • the outlet duct 8 is connected in parallel to each chamber 10, preferably in the region of the respective end 10a of larger cross- section.
  • the machine 1 further comprises means for regulating the pressure inside the loading compartment 5. These means comprise a duct 14 opening in the loading compartment 5 as well as valve means 15 which are arranged in the duct 14 and can put the loading compartment 5 directly into communication with the exterior, ⁇ Fwith a reservoir of gas under pressure, for example, a compressed-air cylinder 16.
  • the valve means 15 are controlled by a system for monitoring the pressure measured inside the compartment 5, for example, by means of a sensor 17.
  • the duct 7 for supplying the bath is connected to the tubular element 6 which is provided with suitably calibrated through-holes in its lateral surface.
  • the bath is thus admitted to the loading compartment from the centre, and is withdrawn in the region of its peripheral edge.
  • the machine 1 operates as follows.
  • the treatment cycle is started.
  • the bath is admitted to the loading compartment 5 through the supply duct 7 and is preferably sprayed in, so as to promote its uniform distribution in the garments and in particular, its penetration into the fabric.
  • the bath is then caused to flow out of the loading compartment in a manner and at times predetermined in accordance with the treatment cycle, through the chambers 10 which in turn are connected to the outlet duct 8.
  • the bath withdrawn from the loading compartment 5 is then regenerated and, if required by the treatment cycle ⁇ is reintroduced into the loading compartment 5 through the supply duct 7.
  • the leaktight closure of the rotary drum 2 advantageously enables the pressure inside the loading compartment 5 to be kept at values higher than the external pressure, by way of non-limiting indication, at up to 0.5 bar relative pressure, preferably at relative pressure values of between 0.2 and 0.3 bar.
  • the increase in internal pressure is achieved by the effect of the loading of the hot bath but can also be modified if necessary by the pressure-regulation means, by virtue of which it is possible to admit air to the drum 2, or to discharge air therefrom.
  • the air necessary to increase the internal pressure may also be admitted simultaneously with the bath, mixed therewith.
  • this shows a second embodiment of the machine according to the invention, generally indicated 100, in which details similar to the previous embodiment are indicated by the same reference numerals.
  • the supply duct 7 is connected to some of the paddles inside the loading compartment 5, which are indicated 109 in Figure 3, instead of to the tubular support element 6.
  • the paddles 109 have, in the region of their vertices 109a, respective output compartments 100, all connected to the supply duct 7, as well as calibrated through-holes for spraying the bath B into the loading compartment 5.
  • Two diametrally opposed paddles 109 are preferably provided in the machine 100, but other configurations are possible.
  • a separation element 115 may also be provided, anchored to the tubular element
  • the outlet duct 8 is arranged to be connected to a collection conduit 20 extending circumferentially around one end of the drum 2 and formed by a pair of facing channel sections 21, 22.
  • the sections 21 and 22 are fixed to the casing la of the machine and to the rotary drum 2, respectively, so that they are movable relative to one another when the drum 2 is rotated about its axis X.
  • a seal 23 is also interposed between the sections 21, 22 to seal the collection conduit 20.
  • the outlet duct 8 is connected to the conduit 20 by means of an opening formed in the section 21 in the region of its lowest point, and each chamber 10 is connected to the conduit 20 by means of a respective opening 24 provided in the section 22.
  • the outlet duct 8 is thus always at a lower level than the bath that is present in the drum 2 so that the withdrawal of the bath can always take place under a hydrostatic head.
  • This arrangement advantageously prevents any problems with the bath-discharge system due to cavitation phenomena which are not unlikely when it is necessary to work at temperatures close to the boiling point of the bath.
  • the two sections 21, 22 are also arranged to be movable apart axially so that the rapid rotation of the section 22 which is fixed firmly to the drum 2 takes place independently and without contact with the section 21.
  • the use of the machine according to the present invention advantageously permits operation with particularly high garment : bath load ratios, by way of indication, of about 1 : 5.
  • a smaller quantity of water and of auxiliary substances such as equalizers, absorbents, sequestrators, deaerators, acids, bases and dyes are consequently used for a given quantity of garments treated and a considerable saving in energy for the heating and movement of the bath is achieved.
  • the present invention thus solves the problem discussed above with reference to the prior art mentioned, at the same time affording many other advantages, amongst which is a treatment which, on the one hand, is more uniform and gentle and, on the other hand, enables a deeper penetration of the bath into the fabrics to be achieved.
  • a further advantage is that it is also possible to operate with baths at temperatures higher than those normally used in conventional machines of the type indicated, thus increasing the versatility of the machine.
  • the present invention enables garments to be treated whilst resulting in less wear of the garments, in particular in the region of the seams.
