Definitions

  • the present invention relates to an apparatus and a method for wet treatment of rope fabric, which have the characteristics specified in the preambles of the attached Claims 1 and 13, respectively.
  • Apparatuses and methods of the above-mentioned type are used in the textile industry for performing operations of finishing of fabrics (such as dyeing, washing, bleaching, etc.).
  • a piece or bolt of fabric which is to undergo treatment is loaded in the form of an endless rope into the apparatus and made to circulate repeatedly through a treatment tank in order to be brought into contact with the liquid.
  • the piece or bolt is made to fold on itself inside the aforesaid tank to assume a lap conformation.
  • the portion in laps of the piece is immersed completely in a bath of liquid which fills the tank of the apparatus.
  • the portion in laps of the piece is, instead, wetted inside the tank by means of sprinklers which form part of a treatment-liquid circulation circuit, the bottom area of the laps being immersed in a bath of liquid formed on the bottom of the tank.
  • continuous circulation of the piece inside the machine is at least in part carried out pneumatically or hydraulically, i.e., exploiting the effect of a jet of air or of a jet of the treatment liquid itself.
  • the purpose of the present invention is to overcome the aforesaid drawback.
  • one first purpose of the present invention is to provide an apparatus and method for wet treatment of rope fabric which will enable the amount of liquid necessary for the treatment process to be contained, i.e., which will enable reduction of the so-called “bath ratio” (understood as the ratio between the amount of the liquid used in the apparatus and the amount of fabric treated).
  • An associated purpose of the invention is to provide such an apparatus and such a method in which the quality and effectiveness of treatment will be ensured even in the presence of a modest level of the treatment liquid inside the tank.
  • Another associated purpose of the invention is to provide such an apparatus and such a method in which, even in the presence of a modest level of the treatment liquid, an efficient movement of the portion in laps of the piece inside the tank will be ensured.
  • a further purpose of the invention is to provide an apparatus that is simple and inexpensive to implement, as well as ensuring safe and reliable operation over time.
  • the reference number 1 designates a treatment tank of the apparatus AT, inside which a piece T of fabric gathered in the form of an endless rope is made to pass in order to be treated with a liquid.
  • the said treatment liquid is a dye.
  • the tank 1 is equipped with a front door 2 and has a substantially circular cross section. Inside the tank there are provided two parallel walls, designated by 1A in Figure 2, for lateral containment of the piece T.
  • the reference number 3 designates sprinkling members set inside the tank 1 and designed to distribute the dye in the form of a spray over the underlying piece T.
  • the various sprinklers 3 are connected together by a distribution manifold 4, the latter being supplied by means of a delivery path 5 which forms part of a dye circulation circuit.
  • the reference number 6 designates a pipe for delivery of water from a water supply (not represented) connected to the delivery path 5 for possible washing of the piece T after the latter has been treated with the dye.
  • the tank 1 has a through filler 7 to which the end of a tube 8 for conveying the piece T is connected, the said tube 8 branching off from one inlet mouth 9 for soaking.
  • a distribution funnel 10 which is designed to bring about, according to known procedures, the laying-out in laps of the piece T as this enters the tank 1.
  • some of the laps obtained for the piece T are designated by FT, whilst the letters TF designate, as a whole, the portion in the form of laps of the said piece T, as this is formed inside the tank 1.
  • the reference number 11 designates a nozzle by means of which dye is introduced into the inlet mouth 9.
  • the nozzle 11 is supplied by means of a respective pump (not illustrated) the delivery of which, designated by 12, is connected to an intake sump 13, the said sump 13 having the purpose of taking up some of the dye bath that gathers in the bottom of the front area of the tank 1. Also reaching the sump 13, via a pipe 14 provided with inlet mouths 14A and 14B, is dye, which gathers in the bottom of the intermediate and rear areas of the tank 1.
  • the reference number 15 designates a motor-driven reel for drawing the piece T that comes out of the tank 1, the piece being guided for this purpose by a guide element 16 and a feeler 17, both being designed according to the prior art.
  • the reference number 18 designates an idler roller for controlling movement of the piece T, the said control roller being provided for guiding the piece T towards the inlet mouth 9.
  • the reference number 19 designates a metre-counter idler roller of a known type used for measuring the length of the piece T at input to the apparatus according to the invention.
  • the reference number 20 designates a reel which is used for carrying out loading of the piece T from an accumulation station 21 to the apparatus AT.
  • the reel 20 is likewise used, at the end of the treatment process in the apparatus AT, for discharging the piece T into the station 21.
  • the tank 1 conveying means for conveying the piece T, the said conveying means being designed to bring about stepwise advance of the portion TF set in laps of the piece T and to improve soaking of the said portion.
  • the aforementioned conveying means are in particular made up of a series of mobile elements 22 basically in the form of parallel bars, between which there are interspaced fixed elements 23, which are also made in the form of parallel bars.
  • Both the mobile elements 22 and the fixed elements 23 extend longitudinally inside the tank 1 in the bottom portion thereof and for at least one prevalent stretch of its length. It may be noted from Figures 1 and 2 how, by means of respective actuating shafts 24, the various mobile elements 22 may assume a raised position with respect to the fixed elements 23 for the purposes that will be clarified in what follows.
  • the reference number 25 designates, as a whole, an electric motor designed for producing rotation of a respective shaft.
  • an electric motor designed for producing rotation of a respective shaft.
  • 25A at the two ends of the aforesaid shaft, which is designated by 25A in Figure 2, there are fitted respective pulleys 26.
  • the reference number 27 designates a further two pulleys, each of which is fitted to one end of a shaft 28. Between the pulleys 26 and 27 are fitted respective belts or chains, designated as a whole by 29.
  • the pulleys 27 likewise define a respective ring gear 27A, on which there is fitted a chain, designated as a whole by 30 in Figure 1.
  • the chain 30 is fitted on the gears 27A associated to the crank mechanisms MA2, ..., MA6. Instead, no pulley 27 is associated to the crank mechanism MA1 since it is not necessary.
  • the rotation of the shaft 25A can be transferred by means of the chains 29 to the pulleys 27 and then, via the various gears 27A and the chains 30, to the shafts 28 forming part of the crank mechanisms MA2, ..., MA6.
  • crank mechanisms MA1, ..., MA6 in four different operating positions.
  • the reference numbers 22 and 23 respectively designate one of the already mentioned mobile elements and one of the already mentioned fixed elements that form part of the means for conveying the piece T.
  • the reference number 24 designates one of the aforesaid actuating shafts for operation of a respective mobile element 22.
  • each shaft 24 is rendered fixed, in a known way, to the respective mobile element 22, whilst the bottom end of each shaft 24 is connected to a joint 31.
  • the joint 31 has a hinge pin 33 for hinging to a disk 33, the latter being fitted to a respective shaft 28.
  • twelve mobile elements 22 are provided, between which are interspaced eleven fixed elements 23.
  • Fitted to each shaft 28 of the crank mechanisms MA1, ..., MA6 are six disks 33 positioned underneath as many fixed elements 23 and aligned to the latter (in particular, underneath the first, third, fifth, seventh, ninth and eleventh fixed element 23.
  • Articulated to the two opposite surfaces of each of said disks 33 by means of a pin 32 are respective joints 31 and shafts 24. In this way, rotation of the shaft 28 enables simultaneous movement of all of the mobile elements 22.
  • Part A of Figure 3 illustrates the same position of operation already illustrated in Figures 1 and 2, i.e., the position in which the mobile elements 22 are in a raised position with respect to the fixed elements 23.
  • Part B of Figure 3 illustrates the condition reached following upon a movement of 90° of the disks 33.
  • the said movement of the disks 33 determines a displacement of the joints 31 and of the shafts 24 such as to produce simultaneously an advance (namely, to the left as viewed in the figure) and a lowering of the mobile elements 22 with respect to the fixed elements 23 until the top surface of the former is aligned or flush with the bottom surface of the latter.
  • Part C of Figure 3 illustrates the condition reached following upon a further movement of 90° of the disks 33. This movement determines a displacement of the joints 31 and of the shafts 24 such as to produce simultaneously a further lowering of the mobile elements 22 with respect to the fixed elements 23 and a recession of the said elements 22 (namely, towards the right as viewed in the figure). In this situation, the top surface of the elements 22 is at a level lower than that of the elements 23.
  • part D of Figure 3 illustrates the condition reached following upon a further movement of 90° of the disks 33.
  • This movement determines a displacement of the joints 31 and of the shafts 24 such as to produce simultaneously a further recession (namely, towards the right as viewed in the figure) and a raising of the mobile elements 22 with respect to the fixed elements 23 until the top surface of the former is again aligned or flush with the bottom surface of the latter.
  • crank mechanism By means of a further movement of 90° of the disks 33, the crank mechanism is brought back to the initial position illustrated in part A of Figure 3, thus obtaining a new raising of the mobile elements 22 with respect to the mobile elements 23 and a simultaneous advance of the mobile elements 22 (i.e., towards the left as viewed in the figure).
  • the mobile elements 22 are driven by means of arrangements basically of the connecting rod-crank type, the joint 31 - shaft 24 assembly constituting the connecting rod, and the disk 33 providing the crank. From another point of view, it emerges clearly how the set of the various crank mechanisms MA1, ..., MA6 forms a system of articulation for the mobile elements 22, which is basically of the articulated-quadrilateral or articulated-parallelogram type.
  • the general operating principle of the apparatus AT is implemented according to substantially known procedures.
  • the operation envisages activation of the above-mentioned pump that feeds the nozzle 11.
  • the consequent jet of liquid at intake to the inlet mouth 9 brings about, in a way in itself known, progressive advance of the piece T along the conveyance pipe 8.
  • the liquid injected by the nozzle 11 traverses the pipe 8 until it reaches the tank 1, to be then distributed inside the tank 1 itself, but always beneath the plane identified by the fixed elements 23.
  • the piece T is deposited on top of the translator apparatus, inside the tank 1 and by means of the distribution funnel 10, in lapped form TF.
  • the piece T is guided by the guide element 16 and by the feeler 17 on the reel 15, which draws along the piece T, the latter being guided by the roller 18 again inside the inlet mouth 9.
  • the piece T is initially soaked in the liquid that flows inside the pipe 8. Inside the tank 1, the laps FT of the portion TF are spray-wetted by means of the sprinklers 3.
  • the primary subject of the present invention regards the fact that there are provided, within the tank 1, specific conveying means 22 for the piece T, which are designed to produce stepwise advance of the portion TF in laps and to improve soaking of the latter.
  • the level of the liquid bath must be kept high in order to reduce passive resistance to the advance of the portion in laps of the piece inside the tank.
  • the quality and effectiveness of the treatment are in any case guaranteed even in the presence of a reduced level of the liquid bath in the tank 1.
  • advance of the piece T along the pipe 8 is at least in part obtained by exploiting the effect of the jet at output from the nozzle 11, namely by means of a hydraulic drawing system. It is however clear that, alternatively, drawing along of the piece T could be obtained by means of an jet of air, i.e., by means of a pneumatic system of a type in itself known.
