Detailed Description

With reference to the figures, a combined device 1 for preparing a mixture for dyeing industrial articles of clothing articles, such as trousers, sweaters, jump pants, jackets, etc., has been shown, the combined device 1 comprising at least a tank 2 for containing a liquid, in particular water, of greater or lesser density.

The water in the containment tank may be, for example, softened water or non-softened water.

According to the non-limiting embodiment shown in the figures, the tank 2 can for example have a base 2a, a top 2b and side walls, if necessary a cylinder 2c extending between the bases. Furthermore, the tank 2 can be arranged with a substantially vertical arrangement or an arrangement inclined with respect to the vertical and horizontal, i.e. with the main development or symmetry axis of the side walls substantially vertical or inclined with respect to the vertical and horizontal.

The combined device 1 also comprises at least one dyeing assembly or filter 3 provided with a basket, which, if necessary, is in fluid communication with the tank 2 by means of suitable conduits so that the liquid (initially in the tank 2 or in its containment and non-filtering portion) can be conveyed inside or through the filter 3 and pass through the natural dyeing substance FS, so that the liquid is dyed by the natural dyeing substance FS.

The filter 3 comprises containing means suitable for containing a colour-releasing element comprising at least one natural dye substance FS. The natural dye substance FS may comprise parts of plants, such as roots, berries, fruits, shells and/or bark, or flowers in general or plants, such as shells, peels, berries, bark, roots, grasses, mushrooms, and/or parts of mushrooms or animals, such as dead and/or air-dried animals and/or animals, or mineral extracts or any other natural substance that releases color, if desired, in the form of flakes, chips or even powder.

As will be determined, the natural dye substance FS releases color to the fluid, so that it does not purify or only allow certain components of the fluid to pass through. Therefore, the expressions of the filter and the color-releasing element must be interpreted according to this definition and other definitions provided for the respective components.

The filter 3 may have the following configuration: having a housing 3a defining a zone CZ for containing one or more natural dye substances FS.

The filter 3 may have a longitudinal axis of symmetry x-x, for example inclined or even vertical with respect to the vertical and horizontal directions. With respect to possible inclinations of the filter 3, the respective longitudinal symmetry axis x-x may define an acute angle with the horizontal plane of between about 10 ° and about 40 °, 50 °, 60 ° or 70 °.

More particularly, the filter 3 may be arranged with an opening or inlet end 3b at a level higher than the corresponding opening or outlet end 3c, so that the liquid, or more precisely the water, passes through the filter from top to bottom, if desired according to a path in a direction inclined with respect to the vertical. The outlet 3c is at a level slightly above the bottom of the tank 2, if desired.

The filter 3 may then comprise a housing means 3d of the natural dye substance FS, such as a grid, a membrane or the like, for defining the portion of the housing zone CZ holding the natural dye substance FS and preventing the natural dye substance from being dragged away or out of their respective positions. Obviously, the containing means 3d do not prevent the passage of liquid.

The natural dye substance FS may be flakes, chips or loose or non-agglomerated powder within the containment region CZ, but is confined by the containment means 3 d.

These substances FS thus define between them a path for the penetration or passage of the liquid.

The subject of the present invention is also a filter as described above for the preparation of a combined set of compounds for dyeing industrial articles or, better still, for an apparatus for dyeing industrial articles such as garments.

Furthermore, a connecting pipe or bypass 4e (visible in fig. 2) can be provided between the filter 3 and the tank 2, in particular between the upper part of the filter 3 and the tank 2 or the storage container or the conveying circuit 4. This tube makes it possible to completely fill the filter with liquid (and therefore completely wet the dye substances contained therein), facilitating the discharge of excess air from the filter 3 to the tank 2 or to the storage tank or to the delivery circuit 4.

The combined device 1 is then provided with a delivery circuit 4 that delivers the liquid taken from the tank 2 into the filter 3 and through the natural dye substance FS, so as to dye the liquid by means of the natural dye substance FS. Obviously, the percolation or passage path for the liquid constitutes part of the conveying circuit 4.

Preferably, also appropriately operated propulsion or suction means, such as a pump 4a, are provided, designed to push or in any case force the liquid to flow along the delivery circuit 4. The pump 4a may for example be arranged at the bottom of the combination 1.

The conveying circuit 4 can extend from the bottom of the tank 2 and then have horizontal and/or inclined and/or vertical sections (with suitable connections) until the conveying circuit 4 reaches a predetermined level at which the inlet opening 3b of the filter 3 is located.

If necessary, heating means are provided, for example coils or resistors (not shown in the figures), mounted in the tank 2 or in any case acting in the tank 2 to heat a liquid, such as water, in particular before it is supplied to the filter 3, so as to promote absorption by the liquid of the colour released by the natural dye substance FS during filtration or during its passage through the latter. Naturally, in this case, the combined device also comprises means for actuating the heating means.

In addition to or instead of what has now been indicated, heating means may be provided around the conveying circuit 4 or inside this conveying circuit 4 and/or in the filter 3, in the latter case, obviously, the heating means will heat the liquid during the feeding of the liquid to the filter 3.

The heating means are for example designed to heat the liquid to a temperature between 40 ℃ and 98 ℃.

Advantageously, the delivery circuit 4 leaves the tank 2, passes through the filter 3 and flows back into the tank 2 or into the storage container, creating a closed or non-closed circuit during which the liquid absorbs colour from the natural dye substance FS contained in the filter 3.

According to the non-limiting embodiment shown in the figures, the conveying circuit 4 is a closed circuit which, for example, exits from the bottom of the tank 2 from which the liquid is sucked, and also returns or terminates in the tank 2, for example at a level close to the bottom, but slightly above the outlet of the tank of the conveying circuit 4, by means of an end duct 4c of the circuit 4.

At least one discharge duct or outflow opening 5a, 5b is also provided for discharging the treated or dyed liquid in the filter 3 towards the washing or dyeing machine.

If desired, two or more discharge ducts or outflow openings 5a, 5b are provided, so that each of the latter can serve two or more washing machines.

In this respect, the discharge conduits 5a, 5b (see fig. 3) may constitute branch arms of the conveying circuit 4.

In this respect, the delivery circuit 4 may comprise a fitting 6 having two or more outlets, each interrupted by a respective shut-off valve 7a, 7b, 7c, a segment 4b (only partially shown in fig. 3) being mounted in an outlet of the delivery circuit 4, for example upstream of the filter 3, while a respective discharge duct 5a, 5b is mounted in another outlet or other outlets. With this structure, it is possible to selectively feed (by means of suitable control of the valves 7a, 7b, 7c) the liquid to the filter 3 or to one or both of the discharge ducts 5a, 5b and thus to the respective washing machine or plant.

Obviously, the discharge conduits 5a, 5b can also leave the tank 2 directly or the storage container for the final compound, in order to dye the industrial products, without consequently intercepting the conveying circuit 4.

Of course, the conveying circuit 4 can also open directly to the outside of the assembly or to the exhaust line, and therefore not be provided to the return section of the tank 3 or to the transfer section of the storage container.

Furthermore, the combined device 1 can also be equipped with an evacuation duct 8 of the tank 2, which evacuation duct 8 starts, if necessary, on the bottom of the tank 2 from a suitable evacuation opening delimited by the tank 2 and is intercepted by a suitable opening/closing valve 9.

The combination 1 may also include a defined or concealed housing 10 for the combination.

In this case, the filter 3 may be supported by a wall of the housing 10, in particular on a side of the housing and/or by the tank 1.

The filter 3 may also be provided with anti-burn protection (not visible in the figures) if desired for reasons of safety and protection for the operator.

The housing 10 may then support a screen or control panel 11 by an operator.

It is obvious that the control of the valves, if electronic, the pumps and any other possible components of the combined device can be delegated to the control unit or PLC of the combined device 1.

The combined device according to the invention may also comprise an electronic control unit or microprocessor to allow automatic management, for example by controlling the temperature, the dye release time, the amount of liquid to be introduced into the machine, and to save the formulation for future repeated treatments.

In this case, the reproducibility of the process parameters and of the preset recipes can be controlled, saved and defined by the central electronic unit.

The combined device may then further comprise a flow meter 4d, which flow meter 4d makes it possible to monitor the feed flow rate of the liquid. The component may be in electrical communication with an electronic control unit.

Then, a colorimeter or sensor for detecting the color of the liquid treated in the filter is provided in the combined device, which is responsible for controlling the level of the absorbed dye, thus informing the electronic control unit of the combined device.

Obviously, the combined device 1 and more particularly the tank 2 or the delivery circuit 4 can also have an opening for the introduction of a liquid, i.e. water, which will be used for the initial filling of the tank or for the flushing phase or dilution of the compound if the dye concentration of the compound is too great. Of course, these steps can be managed by an electronic control unit or even by an operator, according to information or light visible, for example, on a control panel.

Moreover, even if they are not described in general terms, the combined device comprises motorized means and appropriate sensors (if necessary in electrical communication with the electronic unit) with special manual and/or automatic valves for controlling the means of them, and if necessary the components.

According to the present invention, there is also provided a dyeing apparatus comprising a combined device 1 and at least one device for dyeing an industrial article, such as an item of clothing, or a washing or dyeing machine (not shown in the figures), in fluid communication with the tank 2 or with the container or with the filter 3, in order to receive from the device a compound for dyeing the industrial article obtained by filtering in the filter 3 the liquid taken from the tank 2.

More specifically, the or each washing or dying machine is arranged in fluid communication with or served by a respective discharge duct 5a, 5 b. If two or more discharge conduits 5a, 5b are provided, the apparatus comprises two or more washing machines, each connected and communicating with a respective discharge conduit 5a, 5b, so as to be able to receive only the compounds for dyeing from the latter, and therefore both washing machines can be fed simultaneously or not by means of the same combined device.

The invention also relates to a method for preparing a compound for dyeing an industrial article by means of a combined device 1, which method comprises conveying a liquid into a filter 3 and through a natural dye substance FS, so that the liquid absorbs a colorant from the natural dye substance FS contained in the filter 3.

If desired, the method provides a heating step of the liquid, if desired, at a temperature between 40 ℃ and 98 ℃, for example for a time between 5 'and 120' (in the tank 2, in the circuit 4 or in the filter 3), so that the action or absorption capacity of the liquid on the colouring agent released by the natural dye substance FS is enhanced by the action of the heating means before or during the delivery of the liquid into the filter 3.

Advantageously, the treatment method by means of the device according to the invention can also perform the following steps after the liquid has been conveyed into the filter 3 and passed through the natural dye substance FS:

after a certain storage period, returning the filtered liquid to the tank 2 or transferring it to a storage container;

-transferring the compound to be dyed into a washing or dyeing machine, wherein the compound will dye the item of clothing.

Obviously, after the liquid has been filtered and therefore after it has absorbed the colour released by the natural dye substance FS, the dyeing compound can be sent directly to the washing or dyeing machine and therefore not stored in the tank or in the storage container.

Modifications and variations of the invention are possible within the scope defined by the claims.

Thus, for example, the filter may also constitute the final section of the tank, preferably the lower part, or, if desired, it may be placed directly downstream of the tank, so that at least the conveying circuit 4 between the tank and the filter is not designed or in any case will consist of (more or less short) pipes.
