Description
Technical Field
The present invention relates to the field of apparatuses for producing garments. In particular, the present invention relates to a heat recovery device in an apparatus for steam shaping and ironing garments, such as a pressure chamber.
Background
It is known that in the different steps of the production process of articles of clothing such as stockings, socks and the like, the sizing and ironing steps are carried out to size and iron the dyeing and shape of these textile articles.
Devices for setting and ironing textiles are known from us patent 5094371, international published patent document WO2005/100670, us patent 4028817 and us patent 53597886.
The shaping and ironing steps require a given shape, for example in the case of socks, to be provided with a structural shape of the foot, with a shape of the heel and of the toe, and with a shape of the leg.
Generally, the steps of sizing and ironing are performed by subjecting the garments to a heat treatment in a sizing and ironing station on the production line.
In particular, for socks, each sock is placed on a respective support having the desired structural shape. The bracket is typically made of a metallic material.
The sizing and ironing station essentially comprises a pressure chamber with a steam treatment chamber. The socks loaded on the respective supports, arriving in succession at the shaping and ironing station, enter the steam treatment chamber where they are subjected to the action of a steam flow for ironing and shaping their shape. Each sock leaves the pressure chamber with a degree of humidity provided by the steam.
After the ironing step, the textile is passed to a drying station where the textile is dried and its moisture is reduced.
More specifically, the process chamber of the pressure chamber is adapted to selectively close and open itself. In the open condition, the support loaded with the sock can enter the treatment chamber; and in the closed state, performing the step of steam shaping and ironing.
The treatment chamber is provided with a steam flow entering through the supply conduit. This steam flow is then dispersed in the external environment when the treatment chamber is opened to receive the next sock to be shaped and ironed.
In view of the above discussion, it is worth noting that a waste of heat energy occurs in each process step of the sizing ironing device.
The large heat losses increase the energy consumption of the equipment resulting from the relatively extended time required to initially reach the desired temperature within the process chamber and the thermal energy recycled to compensate for the continuous heat losses towards the environment outside the pressure chamber.
Therefore, it is necessary to utilize heat dispersed in the surrounding environment and use the heat in the subsequent drying step.
Disclosure of Invention
The present invention aims to provide a heat recovery device for a device for shaping and ironing garments which overcomes the above-mentioned drawbacks.
A further object of the present invention is to provide a heat recovery device for use in an apparatus for shaping and ironing garments, which is inexpensive and simple to manufacture and which can also be arranged for retrofitting existing apparatuses.
The invention therefore relates to a heat recovery device for use in an apparatus for shaping and ironing garments such as socks, stockings and the like, according to claim 1.
In particular, said heat recovery means are associated with a sizing ironing device.
The sizing ironing device comprises a first shell element and a second shell element which jointly delimit a treatment chamber, an inlet supply duct for supplying a steam flow into said treatment chamber, and an outlet duct for discharging the steam flow out of the treatment chamber once the treatment step of the garments inserted in the treatment chamber has ended.
The sizing ironing device further comprises driving means for driving the first and second shell elements to selectively change the treatment chamber from the open configuration to the closed configuration. Wherein the open configuration enables laundry to be introduced into the treatment chamber and the closed configuration enables laundry to be treated by the steam flow.
The heat recovery device according to the invention comprises at least one heat exchanger fluidly connected to an outlet conduit for a flow of steam. The heat exchanger includes a plurality of conductive elements that pass a steam flow for heating. Further, the heat recovery device includes a ventilation device associated with the heat exchanger that generates an airflow that is directed to a plurality of conductive elements to generate a heated airflow.
The air flow heated by the conductor is directed to the laundry exiting the treatment chamber of the sizing device to dry at least a portion of the laundry.
In this way, the heat recovery means heats the heat exchanger with heat that exits the process chamber (which would otherwise be dissipated). The heat exchanger associated with the ventilation device is capable of heating the airflow surrounding the heat exchanger, the heated airflow being subsequently directed onto the laundry.
The present invention thus achieves pre-drying of laundry that enables a reduction of the subsequent drying time to obtain a great energy saving. Moreover, the action of the ventilation means (capable of rapidly removing the heat from the steam running in the heat exchanger) has a "suction effect" which helps to expel the steam flow out of the treatment chamber; advantageously, this effect enables the minimum pressure required to open the treatment chamber to be reached more quickly at the end of each treatment session, thus enabling the garment just treated to be withdrawn and the next garment to be treated to be introduced. All this thus benefits the accelerated running of the whole process line.
Preferably, in an automatic or semi-automatic production plant, the heat exchanger is arranged downstream of the treatment chamber and upstream of the drying chamber, with respect to the advancement line along the production line. A pre-drying station is thus defined between the treatment chamber and the drying chamber, wherein the heat exchanger together with the ventilation device performs a pre-drying treatment of the textiles leaving the treatment chamber.
Advantageously, the heat exchanger comprises a connection part for connecting the outlet ducts of the process chamber, and at least one pair of cylindrical ducts extending from said connection part, the cylindrical ducts being provided with a plurality of conductive elements.
Preferably, the conductive elements are mutually aligned fins at least partially wrapped around the cylindrical conduit. In this way, the steam flowing inside the cylindrical duct heats the fins, which in turn heat the air coming from the ventilation device.
In particular, the ventilation device is arranged in front of the cylindrical duct, on the other side thereof with respect to the path taken by the laundry, to direct the air flow towards the fins and generate a heated air flow towards the laundry.
Advantageously, the ventilation means comprise at least one axial fan.
Drawings
Further characteristics and advantages of the invention will become clearer from the following description of a preferred embodiment, given without limiting it, and from the attached drawings, in which:
figure 1 schematically shows a heat recovery device in an apparatus for shape forming ironing of garments according to the present invention;
figure 2 schematically shows the above-mentioned styling ironing apparatus comprising said heat recovery means according to the present invention.
Detailed Description
With reference to fig. 1 and 2, there is schematically shown a heat recovery device 10 for recovering heat in an apparatus 1 for shaping (shaping) and ironing (ironing) garments 20 such as socks, stockings and the like.
The sizing ironing device 1, in particular a pressure chamber, comprises a first shell element 2 and a second shell element 3, which are mutually connectable and define a treatment chamber 4. The sizing ironing device 1 also comprises an inlet supply conduit 5 for supplying a flow of steam into the treatment chamber 4 and an outlet conduit 6 for discharging the flow of steam out of the treatment chamber 4 once the treatment step of the garments inserted in the treatment chamber 4 has ended.
The sizing ironing device 1 further comprises driving means 7 for the first shell element 2 and the second shell element 3, said driving means 7 being configured for driving the treatment chamber 4 from an open configuration, in which the garment 20 can be entered, to a closed configuration, in which the garment 20 can be treated with the steam flow. The apparatus 1 is also provided with suitable valve control means 61 for controlling the pressure of the steam inside the treatment chamber 4 and enabling the treatment chamber to be opened only in the event that the pressure drops to a predetermined threshold value.
The steam sizing device 1 comprises a drying chamber 30, said drying chamber 30 being located downstream of the treatment chamber 4 with respect to the advancement path P of the laundry 20. The heat recovery device 10 is operatively arranged between the treatment chamber 4 and the aforementioned drying chamber 30. A pre-drying station 50 is therefore defined between the treatment chamber 4 and the drying chamber 30, this pre-drying station 50 being enclosed by a containment wall 51, said wall 51 being adapted to reduce heat losses towards the outside.
The heat recovery device 10 according to the invention comprises at least one heat exchanger 11 fluidly connected to the outlet conduit 6, said outlet conduit 6 being adapted to discharge a steam flow. The heat exchanger 11 comprises a plurality of conducting elements 12 arranged to be heated by the steam flow. Furthermore, the heat recovery device 10 comprises a ventilation device 13 associated with the heat exchanger 11, the ventilation device 13 generating an air flow 15 directed to the plurality of conductive elements 12 to generate a heating air flow 16.
The hot air flow 16 heated by the conductor is directed to the laundry 20 leaving the treatment chamber 4 to at least partially dry the laundry 20.
In this way, the heat recovery device 10 uses the steam leaving the treatment chamber 4 (which would otherwise be consumed) to heat the heat exchanger. The heat exchanger 11 associated with the ventilation device 13 causes the air flow 15 to wrap around the exchanger, so that the air flow 15 becomes a heated air flow 16 towards the laundry 20. Pre-drying of the laundry 20 is thus achieved, while a substantial energy saving is achieved, reducing the time for the next drying step.
The heat exchanger 11 is arranged substantially side by side with the sizing and ironing device 1 at the output side of the garment 20. More precisely, said heat exchanger 11 is arranged substantially downstream of the treatment chamber 4 and upstream of a drying chamber 30, where the sizing ironing device 1 may be provided.
The laundry 20 in the production line runs and/or stands in front of the heat exchanger 11 (arranged downstream of the treatment chamber 4 of the sizing device 1) to be pre-dried by the heated air flow 16.
Advantageously, said heat exchanger 11 comprises a connection member 6a for connection with the outlet duct 6 of the treatment chamber 4. At least a first cylindrical duct 11a and a second cylindrical duct 11b extend in sequence starting from the connecting part 6a, each provided with a plurality of conductive elements 12.
The conductive elements 12 are stacked fins at least partially encasing the cylindrical tubes 11a, 11 b. In this way, the steam flowing inside the cylindrical ducts 11a, 11b heats the external fins, which in turn heat the air flow 15 surrounding them, said air flow 15 coming from the ventilation device 13. The steam remaining after flowing inside the cylindrical pipes 11a, 11b is returned to the central heating unit 60.
A ventilation device 13, preferably an axial fan, is arranged in front of the other side of the cylindrical duct 11a, 11b with respect to the path followed by the laundry 20.
The operation of the set ironing device 1 and the heat recovery means 10 is briefly described below. The laundry 20 to be treated advances along a forward path P to the treatment chamber 4. The case parts 2 and 3 are moved from an open state enabling the laundry 20 to enter the treating chamber 2 to a closed state enabling the steam treatment of the laundry 20 in the treating chamber 4 in the closed state. The steam flow is thus supplied into the treatment chamber 4 to treat the laundry 20. At the end of the treatment process, the steam contained in the treatment chamber 4 is discharged and flows towards the heat recovery device 10. When the pressure in the treatment chamber 4 is reduced to a desired value, the driving means 7 separates the case unit 2 and the case unit 3 from each other to allow the laundry 20 just treated to exit and the next laundry to be treated to enter.
At the same time, the fan 13 generates an air flow 15 that covers the cylindrical ducts 11a and 11b, which is heated in the vicinity of the latter. The heated air flow 16 thus enables the laundry 20 leaving the treatment chamber 4 to be at least partially dried before entering the drying chamber 30 located downstream. The remaining steam flow exiting from the heat exchanger 11 is not dissipated in the external environment, but is sent again to the central heating unit 60.
The heat recovery device 10 configured as such allows to obtain some advantages already evident from the above description, in particular a considerable saving of total energy in the plant for producing and treating garments provided with the device, while at the same time allowing to save significantly time, thus increasing the production per unit of time.
It should be noted that the heat recovery device 10 has a further advantageous effect. The operation of the ventilation device 13 enables the rapid removal of the vapour flowing inside the heat exchanger, thus accelerating the cooling/condensation phase of the gases remaining in the treatment chamber 4, resulting in a "suction effect" which facilitates the exit of the vapour flow from the treatment chamber; this way it is possible to reduce the pressure in the process chamber 4 to the required minimum value in a relatively faster way at the end of each process session, thus generally benefiting from a faster running of the entire process line.
