Definitions

  • the present invention relates to the technical field concerned with the apparatuses for treating of stockings.
  • the present invention relates to an apparatus for steam fixing of woman stockings, like tights or the like.
  • Apparatuses for controlling, fixing and drying of stockings are known, which generally comprise a rotating turret, able to transport subsequently the stockings to be treated up to the various operating stations, comprising a stockings inserting station and a stocking extraction station.
  • Patent N. 1225876 shows, by example, a fixing apparatus in which the steam chamber has opposite lateral walls, one of which is fixed, and the other one is movable to allow the chamber to be closed, for introducing the steam, and then the chamber to be opened, thus allowing molds to be moved.
  • pressing pads are mounted, fit to engage and to compress stockings on their molds, when the steam chamber is in its closed position.
  • the apparatus comprises a double steam chamber fit to receive, while in an open position, respective pairs of molds.
  • Said steam chamber is made of two symmetrically movable shells, fit to be sealingly coupled at their respective front edges; the cited shells, when in their closed position, have internal walls which cling to the molds .
  • opening the fixing chamber walls causes a sudden drop in temperature, so providing evident problems due to condensation forming, together to a steam dispersion.
  • the last fact causes some energy wasting, and makes the working environment less comfortable.
  • a further drawback is due to the high amount of time the molds stay into the steam chamber. In fact, that time affects the cycle rate of the others operating phases, which are usually faster; increasing that time means reducing the apparatus productivity.
  • reducing the fixing time below a treshold value compromises the success of thermal treatment .
  • an apparatus for steam fixing of stockings or similar articles which comprises a case (17) , internally defining a steam chamber (18) , having a flattened shape along a longitudinal plane coincident with a forwarding plane for moulds (2) , which are upwardly supported and oriented downwardly, the said case (17) being provided, at its entrance and at its exit, of closing doors (19) , and being also provided, at its upper part, with a longitudinal slit (21) , fit to allow said molds (2) to pass along the said steam chamber (18) , said slit (21) being also fit to be closed around the molds (2) by sealing means (22) .
  • FIG. 1 shows a schematic plain view of an apparatus for treating woman stockings, of the tights type,-
  • FIG. 2 shows a side view of the apparatus of figure 1;
  • FIG. 3a and 3b show a vertical section view of the fixing station of the above mentioned apparatus, in various operating phases;
  • FIG. 4 shows a partial upper view cf said fixing station
  • FIG. 5a and 5b show a view of a detail of said fixing station, according to the section plane V-V of
  • 1 indicates an apparatus for controlling, steam fixing and drying of woman stockings, of the type of tights or the like .
  • Apparatus 1 carries and moves in an intermittent way, according to a ring path, a series of molds 2, arranged in pairs and fit to inserting on each of them corresponding stockings to be treated.
  • Molds 2 are made of suitably shaped solid glass bodies. More particularly, as can be seen in Fig. 2, molds 2 have a flattened shape, and an outline getting narrower towards their free end, which substantially corresponds to the stockings feet .
  • Molds 2 are turned downwardly, in order to allow stockings to be inserted from down upwards, and they are held upwardly, by means of respective stems 3, by a pair of chains 4, defining the said ring path.
  • the ring path extends along a longitudinal direction defined by a fixed frame 5.
  • the chains 4 wrap around a pulley 6 at one end of the frame 5, and around a corresponding pair of reels at the opposite end of the same frame 5.
  • Pulley 6 is operated by an engine member 8, for intermittent]y forward the molds 2.
  • Operating the engine 8 allows to move the molds 2 successively to a station 9 for loading the stockings to be treated; to a station 10 for controlling said stockings for defects; to first station 11 and to a second station 12 for discarding defective stockings; to a station 13 for fixing the non-defective stockings into a suitable steam chamber; to a drying station 14; and finally to a station 15 for extracting stockings and for driving away them.
  • the pairs of molds 2 are suitably rotatable, one with - 6 -
  • Molds 2 are carried back to their spreaded position upstream of the loading station 9.
  • the fixing station 13 is provided with a case 17, defining the steam chamber 18.
  • the case 17 has a shape which is flattened about a longitudinal plane coinciding with the molds 2 forwarding plane.
  • the case 17 is provided, at the entrance and at the exit of the steam chamber 18, with closing doors 19, sideways hinged about pivots 20 having vertical axis.
  • the molds 2 pass through a longitudinal slit 21 made en the upper wall of the case 17 (see Fig. 3a) .
  • the slit 21 is fit to be closed, around the molds 2, by a pair of bulkheads 22, which are hinged about respective shafts 23, longitudinally mounted sideways of the case 17; bulkheads 22 can swing, respectly driven by a first jack 24 and by a second jack 25, by means of respective compound levers 26,27.
  • Each one of the bulkheads 22 carries a pair of packings 28,29, extending longitudinally with respect to the said bulkheads 22 and arranged on perpendicular faces of the same, which respectively constitute a bottom face and a side face when they are in a configuration closing the slit 21 (see Fig. 3b) .
  • Bottom packings 28 are fit to make a seal by contact with the said upper wall of the case 17, while the side packings 29 make a seal by respectively contacting one each other. (see Fig. 3b) .
  • packings 28,29 are made of elastic material, so that they can wrap around molds 2 passing through the slit 21, thus making a seal with the said molds 2.
  • An optimum seal of packings 28,29 on molds 2 is achieved because the said molds 2 are made of glass, and because they are moistened by the steam contained into the fixing chamber 18.
  • the bulkheads 22 are put in contact with corresponding sealing packings 30, mounted on doors 19.
  • doors 19 are integral with arms 31, hinged on the above mentioned pivots 20; on each door 19 at least two closing arms
  • Each of the closing arms 31 is bended, by means of an appendage 32, to the stem 33 of a respective jack 34, which is hinged, in its turn, sideways of the case 17.
  • the jack 34 operates the rotation of arms 31 between the door 19 opening position, which is indicated with a dashed line 31a in Fig. 4, and a closing position.
  • clamping members 35 of the doors 19 are provided, fit to ensure a suitable closing force for pressure sealing the fixing chamber.
  • the clamping members 35 comprise a latch 36, which is driven for vertically sliding over rails 37, on a side of the case 17, and which is operated with a reciprocating motion by means of an actuating member 38, the latter being fixed to the same case 17.
  • the latch 36 is provided with two protruding, conical-ended pivots 39, placed at suitable heights and vertically coaxial. Pivots 39 are fit to engage, when in the clamping position, corresponding vertical holes 40, made on the closing arms 31; when in said position, they force the closing of the closing arms 31 by means of their conical end.
  • the chamber 18 i ⁇ fit to be fed with steam by means of a known system, in order to perform the fixing of stockings carried by molds 2 inside the same chamber 18.
  • the jacks 34 open the doors 19 by operating the arms 31, which are rotated to their opening position 31a (see Fig. 4) while, at the same time, jacks 24,25 rotate the bulkheads 22 to the opening position 22a of slit 21, being said position raised from the case 17 (see Fig. 3a) .
  • molds 2 proceed on a plane which is vertical and longitudinally median with respect to the case 17, in the direction which has been indicated with an arrow A.
  • the position reached by a mold at the entrance of the case 17 has been indicated with 2a. Molds 2 pass through the slit 21 placed on the upper side of the case 17.
  • Opening the steam chamber 18 is made in the opposite way, at the end of the fixing phase, in order to allow the molds 2 to be moved forward
  • the fixing chamber 18 extends straightly and longi udinally with respect to che forwarding direction of molds 2. This allows multiple pairs of molds 2 to be inserted into the fixing chamber 18, e.g. three pairs of molds 2, as shown in Figures 1 and 2.
  • Another advantage due to the straight arrangement of the fixing chamber 18 is that molds 2 are not subject, during their forwarding, to any centrifugal force, which could cause some kind of molds oscillations; thus, there is no risk for stockings to be damaged by touching the internal walls of the fixing chamber 18.
  • the fixing chamber 18 is of very small size, particularly in its width, which is only large enough to arrange the molds 2. It is to be noted that all the chamber 18 closing members and all the molds 2 moving members are placed externally with respect to the case 17. As a result, the steam consumption for fixing the stockings is very low.
  • a very important feature of the fixing apparatus of the present invention is that the case 17 defining the steam chamber 18 is substantially closed for the whole operating cycle.
  • the case 17 is opened only ac its entrance and exit doors 19, and at the slit 21, for a short period of time, which is enough to allow the molds 2 to come in to, and to go cut from, the fixing chamber 18. Therefore, there is no steam waste in the working environment. as for the traditional fixing apparatuses; this allows saving energy and improves the workers operating conditions.
