Description

The present invention relates to a new machine

  aqueous treatment such as dyeing, bleaching, washing, boiling

  textiles, such as fabrics or made-up articles, in particular and in particular to a new machine for dyeing such textile articles that are ready to be dyed, that is to say having already undergone the usual treatments of preparation for the dye; the present invention also relates to a method of aqueous treatment of textile articles such as fabrics or made-up articles. The machines for dyeing made-up textile articles proposed in accordance with the prior art are of two types: 1) the pallet boats in which the articles to be dyed are immersed require a very long bath ratio, of the order of 1 / 30 to 1/100 which leads to a very high consumption of water, reagents

  treatment and energy; such an economic balance sheet

  a vantage point tends to accelerate their disappearance.

  2) horizontal-axis drum machines, whose bath ratio is shorter than the bath ratio of the boats, since it is of the order of 1/8 to 1/35, which entails significant savings of water, treatment reagents, energy, at the same time as the reduction

  the volume of waste water, which results from the

  considerable bath ratio, is a favorable factor for the environment by minimizing the problems and costs associated with the evacuation of industrial effluents. The drum, rotating about a horizontal axis, of these machines, is subdivided into several compartments, generally 2 or 3, large capacity, by radial partitions extending from the central axis of the drum to the inner periphery of this last. However these machines are not entirely satisfactory, far from it because: - their bath ratio is still too long in terms of water savings, energy and reagents necessary to improve the competitiveness of the dyeing operations d made-up textile articles; - The drum of these machines rotates at a fast rotational speed (5-35 rpm), which causes the "pilling" of items in the compartments and their entanglement in each other, especially when the products to dye are pants, shirts, socks and that

  the capacity of a compartment exceeds 15 to 20 kg.

  In such a case, the homogeneity of the dyeing is not assured, and the entangled clothes in each other must be separated manually, which increases

operating costs.

  In addition, the loading and unloading of dyed articles is done by the same front door, which

  is a cause of difficulty and a waste of time.

  The object of the present invention is to provide an aqueous treatment machine for textile articles such as fabrics or made-up articles, in particular, which better meets the requirements of the practice than the machines aimed at the purpose of the mirror proposed in the art. previous, in particular in that it ensures a great

  homogeneity of the dyeing without pilling or entangling-

  treated articles, in that it works with

  a much shorter bath ratio than is allowed

  the machines of the prior art, in that it therefore entails considerable savings in water, energy, process reagents and manpower, in that it is easier to load and to discharge than the machines for processing made textile articles known in the prior art, which provides a time saving which reduces the duration of a treatment cycle and

  increases the efficiency of the machine.

  The subject of the present invention is a processing machine

  aqueous treatment of textile articles such as fabrics or

  born, in particular of the horizontal axis type, which is characterized in that it comprises a fixed cylindrical vessel in which is mounted a structure subdivided into a plurality of compartments assigned a rotational movement about the central axis of said vessel, to the interior of the latter, which compartments are arranged to be juxtaposed and are arranged in such a way in the fixed cylindrical vessel that their partition facing the central axis of the tank is

  located at such a distance from the central axis that the assembly

  The compartments are arranged in a ring in the tank.

contact with the treatment bath.

  In addition to the foregoing provisions, the invention

  takes further steps, which will emerge from the

description that will follow.

  The invention will be better understood by means of the

  description which will follow, which refers to the drawings

  in which: Figures 1 to 5 are cross-sectional views of five different embodiments of an aqueous treatment machine for textile articles such as fabrics or articles

  made, in particular, according to the invention.

  It must be understood, however, that these drawings

  and the corresponding descriptive parts are given uni-

  as an illustration of the object of the invention,

  which they do not constitute in any way a limitation.

  The aqueous treatment machine, and especially the dyeing machine, of textile articles such as fabrics or made-up articles, 29, represented in FIG. 1, consists of a cylindrical tank 1 fixed to

  horizontal axis in which is mounted a structure 2 with horizontal axis

  tal which is able to be rotated around its ax of

  6. This structure 2 has the shape of a crown defining

  formed by a circular inner partition 5 which is advantageously but not necessarily perforated, and by an outer partition 4,

  also advantageously but not compulsorily perforated.

  No. 2 is subdivided into a plurality of subcategories by

  side sounds 3 which can be punched or not.

  These lateral partitions may be radial, or

  radial as shown in FIGS. 1 to 4 and they may be rectilinear lines (3,3a, 3b), as shown in FIGS. 1 to 3, or curves (3c)

  as shown in Figure 4, or present any suitable profile.

suitable.

  The outer partition 4 of each compartment 30, 30b or 30c is advantageously equipped with an access door for loading and unloading said coapartiment, or it can itself constitusr

  this door, the unloading of an ooiartirnt being done when

  this is next to the loading door 7 which is equipped with the fixed tank 1 and unloading it when the compartment 30, 30b or 30c is opposite the unloading door 10 of which is

  also equipped with the fixed bowl 1.

  While in Figures 1,3 and 4 compartments 30,30b and c are each provided with an outer wall 4 which constitutes or ctrends an access door to each given compartment, in Figure 2, the outer walls 4 are removed , compartments 30a being

  closed by the inner wall of the fixed vessel 1 itself.

  The realization of the lateral partitions 3,3a, 3b, 3c so that they are non-radial, promotes the loading of articles to

  in the machine and unloading them, because of the inclination

  the sound of these partitions which during the loading operation prevents slipping out of the tank of the loaded articles and during the operation

  discharger, on the contrary, favors the slipping of the articles

  in the handling trolley in place in front of the door of the

unloading 10.

  The axis of rotation 6 of the structure 2 is supported by beams 8. The structure 2 subdivided into compartments 30, 30a, 30b or 30c by the side walls 3, 3a, 3b or 3c, is rotated by a

  driving motor 9 integral with the axis of rotation 6.

  The tank 1 is supported by fixed tank supports 17 on the beams 8. The treatment bath is introduced from a preparation tank 15, by an injection device 20 and a bath injection tube 25. The circulation of the treatment bath is ensured by the pump 11, between the outlet 13 of the bath of the tank 1 and the return 14 of the bath in the tank 1 and its maintenance at the required treatment temperature is ensured by an exchanger 12 interposed in the return circuit 14 of

bath in the tank 1.

  The level 23 of the bath in the tank 1 is detected and controlled by adjustment means advantageously

  constituted, for example, by a float tube 16.

  The treatment bath is located at the lower part of the fixed vessel 1 and each compartment 30, 30a, b or 30c during the rotation of the structure

  immerse yourself in the bath to get out of it because of the

  following the rotation of the structure 2.

  The processing machine shown in the figure differs from the embodiments shown in Figures 1 to 4, in that the ring-shaped structure 31 which is rotated in the vessel 1 consists of contiguous compartments 32, sheet metal perforated or not, substantially cylindrical or spherical, arranged in a circle 33, each connected to the axis of rotation 6 by an arm 35 on which each coapartiement cylindrical or spherical is to

  rotation through its axis 34 of such

  However, all of the compartments 32 which form the ring-shaped structure 31 rotate about the axis of rotation 6 common to said structure 31 and to the vessel 1, and that each compartment 32 rotates about its axis of rotation.

rotation 34.

  The loading and unloading of the cylindrical or spherical compartments 32 take place when a given compartment is in operation.

  look at the corresponding door 7 or 10 of the fixed tank 1, after-

  This duidit compartment is provided with, for example, a hinged door. The processing machine according to the present invention makes it possible to process larger quantities of products per treatment cycle than the machines of the prior art believe. It also makes it possible to obtain a better quality of dyeing due to

  subdivision of the rotating structure into a large number of oxmpar-

  timings and the smooth movement of the articles treated in each of the

  which is favrozed by the shape of the compartments and

  the fact that their base does not have an acute angle, to which

  in addition, where appropriate, with regard to the methods of

  FIGS. 1 to 4 show the non-radial disposition of the partition walls of the adjacent compartments, which favors the

  moving articles in the compartments.

  As a result, the crown subdivided into compartments 30,30a,

  b, 30c or 32, should not be affected, as was the case with

  rotating ball of the prior art, a high speed, which has the effect of exerting less stress on the treated articles whose texture and condition are better respected than in the past, and to avoid the disadvantages related to pilling and poor movement of

treated articles.

  It has been found in practice that satisfactory results are obtained by rotating the crown at speeds of the order of 1 rev / min, or even less, at 4 or 5 revolutions / minute.

  speed given only by way of non-limiting examples.

  As is apparent from the above, the invention is not limited to those of its modes of implementation, implementation and application which have just been described more explicitly; on the contrary, it embraces all the variants that may come to the mind of the technician in the field, without departing from the framework, nor

  of the scope of the present invention.
