    Description

    FIELDS OF THE INVENTION



    [0001] The present invention relates to the field of the machines for the production of garments, in particular, refers to a machine for steam setting and finishing garments, for example an autoclave, comprising a heat-recovery equipment.

    STATE OF THE ART



    [0002] It is known, among the different steps of production of garments such as hosiery, socks and the like, a fixing and finishing step which is performed for fixing and finishing both the colour and the shape of such textile articles.

    [0003] Machines for fixing and finishing textile articles are known from US5094371, WO2005/100670, US4028817 and US53597886.

    [0004] The fixing and finishing step is required to give a particular shape, for example, in the case of a sock, to give the latter the anatomical shape of the foot, thus the shape of the heel and toe, and the shape of the leg as well.

    [0005] Generally, the fixing and finishing step is carried out by submitting the garment to a thermal treatment in a fixing-finishing station of a production line.

    [0006] Specifically, in the case of the socks, each sock is put on respective support having a desired anatomical shape; the support is generally made of a metallic material.

    [0007] The fixing and finishing station mainly comprises an autoclave with a steam treatment chamber. The socks arriving sequentially in the fixing and finishing station - boarded on the respective support - enter the steam treatment chamber where they are subjected to a steam flow for ironing and fixing the shape thereof. The sock leaves the autoclave with a certain humidity degree provided by the steam.

    [0008] Subsequently to the fixing step, the textile enter in a drying station where it is dried and the humidity degree thereof is reduced.

    [0009] More particularly, the treatment chamber of the autoclave is conformed to selectively close and open itself. In the open position, the support with the boarded sock is enabled to enter the treatment chamber; in the closed position the steam fixing-finishing step takes place.

    [0010] The treatment chamber is supplied with a steam-flow entering through a supplying conduit. Such a steam flow is then dispersed in the environment when the treatment chamber is opened to receive the next sock to the fixed and finished.

    [0011] In view of what above discussed, it is worth noting that a waste of thermal energy occurs at each treatment cycle of the fixing-finishing machine.

    [0012] The considerable heat dispersion entails an increase of the energy consumption of the plant, due both to the extended time which is initially required to reach the desired temperature in the treatment chamber, and to the thermal energy to be supplied cyclically to compensate for the continuous dispersion of heat to the environment outside the autoclave.

    [0013] It is therefore felt the need for exploiting the heat dispersed in the environment and making use of such a heat in the subsequent drying steps.

    SUMMARY OF THE INVENTION



    [0014] An object of the present invention is to provide a machine for fixing-finishing garments comprising a heat-recovery equipment that overcomes the above described drawbacks.

    [0015] A further object of the present invention is to provide a heat recovery equipment, in a machine for fixing and finishing garments, which is economically advantageous and simple to construct, and which can also be arranged for retrofitting existing plants.

    [0016] The present invention thus relates 2. to a machine for fixing-finishing garments, such as socks, hosiery and the like, according to claim 1.

    [0017] The fixing-finishing machine comprises a first shell-portion and a second shell-portion defining together a treatment chamber, an inlet supplying conduit for supplying a steam-flow into the treatment chamber and an outlet-conduit for evacuating the steam flow out of the treatment chamber once the treatment step of the garment inserted therein is over.

    [0018] The fixing-finishing machine further comprises actuating means for actuating the first and second shell portions, in order to selectively drive the treatment chamber from an opened configuration - which enables garments to be introduced therein- and a closed configuration which enables the garments to be treated with the steam flow. The heat-recovery equipment according to the present invention comprises at least a heat-exchanger in fluid connection with the outlet conduit for the steam flow. The heat-exchanger comprises a plurality of conducting elements to be heated by the steam flow. Furthermore, the heat-recovery equipment comprises ventilation means, associated to the heat-exchanger, that generate an air flow directed to the plurality of conducting elements to produce a heated air flow.

    [0019] The air flow, heated by conduction, is directed to the garments exiting the treatment chamber of the fixing-machine, in order to at least partially dry them.

    [0020] In this way, the heat-recovery equipment makes use of the heat exiting the treatment chamber, otherwise dispersed, for heating the heat-exchanger. The latter, associated to the ventilation means, enables to heat an air flow lapping the heat-exchanger, the heated air flow being subsequently directed onto the garments.

    [0021] Therefore a garments pre-drying is achieved that enables to cut subsequent drying times and to obtain a considerable energy saving. Furthermore, the action of the ventilation means which quickly remove heat from the steam running in the heat-exchanger, has a "suction-effect" which helps the steam flow to be evacuated out of the treatment chamber; advantageously, this enables to reach faster, at the end of each treatment cycle, the minimum pressure required for permitting opening of the treatment-chamber, thus enabling the just treated garments to go out and enabling introduction of the next garments to be treated. All this therefore entail a general advantageous speeding up of the entire treatment line.

    [0022] Preferably, in an automatic or semi-automatic production plant, the heat-exchanger is arranged, with respect to the advance path along the production line, downstream of the treatment-chamber and upstream of the drying chamber. A pre-drying station is therefore defined between the treatment chamber and the drying chamber, in which the heat-exchanger together with the ventilation means exert the pre-drying action on the textile articles leaving the treatment chamber.

    [0023] Advantageously, the heat-exchanger comprises a connection portion for connecting to the outlet conduit of the treatment chamber, and at least a pair of column-conduits extend from the connection portion and are provided with the conduction elements.

    [0024] Preferably, the conduction elements are fins mutually aligned that coat at least partially the column-conduits. In this way, the steam flowing inside the column-conduits heats the fins which in turn heat the air coming from the ventilation means.

    [0025] In particular, the ventilation means are arranged in front of the column-conduits at the opposite side with respect to the passage of the garments, so as to direct the air flow to the fins and generate the heated air flow addressed to the garments.

    [0026] Advantageously, the ventilation means comprise at least an axial fan.

    BRIEF DESCRIPTION OF THE FIGURES



    [0027] This and further features and advantages of the invention, will be more clearly described with reference to a preferential and not limitative embodiment, and to the enclosed drawings, in which:
    Figure 1 shows schematically a heat-recovery equipment in a machine for fixing-finishing garments, according to the present invention;

    DETAILED DESCRIPTION OF THE INVENTION



    [0028] With reference to figure 1, there is schematically shown a heat-recovery-equipment 10 for recovering heat in a machine 1 for fixing and finishing garments 20, such as socks, hosiery and the like.

    [0029] The fixing-finishing machine 1, in particular an autoclave, comprises a first shell portion 2 and a second shell portion 3 mutually coupleable and defining a treatment chamber 4. The fixing-finishing machine 1 further comprises an inlet supply conduit 5 for supplying a steam flow into the treatment chamber 4 and an outlet conduit 6 for evacuating the steam flow out of the treatment chamber 4 once the treatment step of the garment inserted therein is over.

    [0030] The fixing-finishing machine 1 further comprises actuating means 7 for the first 2 and second 3 shell portions, which are configured for driving the treatment chamber 4 from an open configuration which enables introduction of the garments 20, and a close configuration that enables to treat the garments 20 with the steam flow. Suitable valve control means are provided for controlling the steam pressure inside the treatment chamber 4 and for enabling the latter to be opened only when the pressure falls to a prefixed threshold value.

    [0031] The fixing-finishing machine 1 comprises a drying chamber placed downstream of the treatment chamber 4 with respect to an advance path of the garments 20. The heat-recovery equipment 10 is operatively arranged between the treatment chamber 4 and the abovementioned drying chamber. A pre-drying station therefore is defined between the treatment chamber 4 and the drying chamber, such a pre-drying station being enclosed by containing walls suitable for reducing the thermal dissipation to the outside.

    [0032] The heat-recovery equipment 10 according to the present invention comprises at least a heat-exchanger 11 in fluid connection with the outlet conduit 6 for evacuating the steam flow. The heat-exchanger 11 comprises a plurality of conduction elements 12 arranged to be heated by the steam flow. Furthermore, the heat-recovery equipment 10 comprises ventilation means 13 associated to the heat-exchanger 11 which generate an air flow 15 directed to the plurality of conduction elements 12 to give rise to a heated air flow 16.

    [0033] The warm air flow 16, heated by conduction, is directed to the garments 20 leaving the treatment chamber 4 in order to at least partially dry the garments 20.

    [0034] In this way, the heat-recovery equipment 10 takes advantage of the steam - otherwise dispersed - leaving the treatment chamber 4, for heating the heat-exchanger 11. The heat-exchanger 11, associated to the ventilation means 13, generates the air flow 15 that licks the exchanger thus turning into the heated air flow 16 which is addressed to the garments 20. Therefore a pre-drying of the garments 20 is achieved which entails a considerable energy saving and time reduction for the next drying step.

    [0035] The heat-exchanger 11 is substantially arranged side by side to the fixing-finishing machine 1 at the output side of the garments 20. More precisely, the heat-exchanger 11 is substantially arranged downstream of the treatment chamber 4 and upstream of a possible drying chamber with which the fixing-finishing machine 1 is provided.

    [0036] The garments 20, in the production line, run and/or stand in front of the heat-exchanger 11 - arranged downstream of the treatment chamber 4 of the fixing machine 1 - for being pre-dried through the heated air flow 16.

    [0037] Constructively, the heat-exchanger 11 comprises a connection-portion 6a for the connection to the outlet conduit 6 of the treatment chamber 4. From the connection-portion 6a at least a first and a second column-conduits 11a extend in sequence, each being provided with conduction elements 12.

    [0038] The conduction elements 12 are pack-stacked fins that coat at least partially the column-conduits 11a. In this way, the steam running inside the column-conduits 11a heats the external fins which in turn heat the air flow 15 lapping them, which comes from the ventilation means 13. The residual steam, after running internally the column-conduits 11a, is returned to a central boiler unit.

    [0039] The ventilation means 13, preferably an axial fan, is arranged in front of the column-conduits 11a at the opposite side with respect to the passage of the garments 20.

    [0040] In the following it is briefly described the functioning of the fixing-finishing machine 1 and of the heat-recovery equipment 10. The garments 20 to be treated are advanced along the advance path, through the treatment chamber 4. The shell portions 2, 3 are moved from the open configuration, to enable the garments 20 to enter the treatment chamber 4, to the close configuration, which enables steam treatment of these garments 20 in such a treatment chamber 4. A steam flow is therefore supplied into the treatment chamber 4 to treat the garments 20. At the end of the treatment, the steam contained in the treatment chamber 4 is evacuated and is left to flow to the heat-recovery equipment 10. When the pressure in the treatment chamber 4 falls to the required value, the actuating means 7 decouple the shell portions 2, 3 from one other to enable the just treated garments 20 to exit, and to enable entry of the next garments to be treated.

    [0041] In the meantime, the fan 13 generates an air flow 15 that invests the column-conduits 11a and is heated thereby. The heated air flow 16 directed to the garments 20 leaving the treatment chamber 4 are thus at least partially dried, before entering the drying chamber located downstream. The residual steam-flow which exits from the heat-exchanger 11 is not dispersed in the environment, but is sent again to the central boiler unit.

    [0042] The so configured heat-recovery equipment 10 enables several advantages to be achieved, which are already evident from the above description, and in particular enables to reach a considerable overall energy saving in a plant for production and treating of garments in which such an equipment is provided, and also enables to reach a noticeable time saving, and thus an increase of the output per hour.

    [0043] It should be noted that a further advantageous effect is achieved owing to the heat-recovery equipment 10. The action of the ventilation means 13 that quickly remove heat from the steam running in the heat-exchanger and that thus speed up the cooling/condensation phase of the fluid leaving the treatment chamber 4, cause a "suction effect" which helps evacuation of the steam flow out of the treatment chamber; this enables, at the end of each treatment cycle, to cut the pressure in the treatment chamber 4 to the required minimum value in a faster way, thus achieving a general advantageous speeding up of the entire treatment line.
