Definitions

  • the present invention relates to a machine for softening and shrinking a fabric.
  • An object of the present invention is also a method for softening and shrinking a fabric.
  • Machines have been marketing for many years now for continuous processing of a fabric; these machines improve the tactile characteristics thereof, in particular softness and shrinkage.
  • Machines are known, for instance, that provide for impacting a wet fabric between two impact structures arranged at the ends of a pneumatic transport tunnel. This impact results in fabric softening, shrinking and settling.
  • FI2004A000183 and FI2008A000100 of the same applicant, and in the international patent applications WO2006/021978 and WO2009/14184 claiming respectively the priority of the aforesaid Italian applications.
  • each blowing device (lower device on the tunnel bottom and upper device on the tunnel top) has two channels diverging from the compartment towards the tunnel, i.e. inclined with respect to the direction in which the tunnel extends and the fabric is fed.
  • the lower pair and the upper pair of channels are substantially arranged at the same longitudinal height as the tunnel.
  • the air pushing and pulling the fabric is recovered through a suction system; this latter may be provided, for instance, with suction areas at the tunnel ends (for example in front of the impact structures that are adequately holed) or/and with suction holes on the top and/or bottom of the tunnel.
  • the air not only moves the fabric, but also allows the drying thereof.
  • the object of the invention is to provide a machine for processing a fabric through impact, to soften and shrink it, as well as a related method, providing for an optimum flexibility in adjusting the air quantity and the tunnel transit time of the fabric, so that it can be suitable for different fabric types.
  • the invention relates to a machine for processing a fabric, comprising
  • the invention also relates to a method for softening and shrinking a fabric, preferably a knitted fabric; the method provides for pulling or pushing the fabric, through air flows below and/or above the fabric, alternatively towards opposite impact structures, against which the fabric impacts; the directions of these air flows are inclined relative to the horizontal, so as to create a resulting horizontal component of the air push or pull on the fabric allowing to move it.
  • the method characteristically provides for a step, wherein the resulting horizontal component of the air push or pull on the fabric is null, i.e. wherein the air invests the fabric without moving it towards a respective impact structure.
  • the method practically provides for a step wherein the resulting horizontal component of the air push on the fabric is inverted, so as to invert the fabric movement, or alternatively a distinct step of making this resulting horizontal component of the air push null, so as to stop the fabric movement.
  • a machine according to the invention is indicated as a whole with number 10. Only the fundamental components thereof will be described below.
  • the figures show a machine configured for processing a (preferably wet) fabric in open width, i.e. laying according to its transverse direction.
  • the machine according to the invention can be also designed for processing a fabric in rope form.
  • the machine substantially comprises a preferably horizontal path 11, which is at least partially pressurized and along which an open-width fabric T, such as preferably a knitted fabric, moves, and a bidirectional pneumatic transport system 12 fed by a pneumatic circuit 13, as well as a further pneumatic circuit 14 for air suction and recirculation.
  • the transport system provides for a tunnel 15 defining at least one part of the fabric path. In this example, this path 11 is horizontal, at least as regards the inner extension of the tunnel. In other embodiments the tunnel may obviously be inclined or slightly inclined.
  • Two impact structures 16 and 17 are arranged upstream and downstream of the tunnel 15; in this example these structures are in the form of grilles, against which the fabric impacts, as better explained below.
  • the machine according to the invention advantageously includes, at the ends of the path 11, below the impact structures 16 and 17, respectively a first treatment tank 18 and a second treatment tank 19, in which a stock of fabric forms alternatively.
  • the stock formed by the wet open-width fabric T is accumulating in the tank 19 and the pneumatic transport system 12 is configured so as to take the fabric T from the tank 18 and transfer it in the tank 19 to form said stock.
  • the pneumatic transport system 12 directs pressurized air, through two blowing devices 20 and 21, arranged respectively above and below, substantially in the same longitudinal position along the tunnel 15 in which the fabric is pneumatically transported.
  • Each blowing device 20-21 has an air supply duct 20A-21A or compartment ending with two diverging channels 20B'-21B' and 20B"-21B" oriented inclined with respect to the direction of longitudinal extension of the tunnel 15, i.e. the fabric feed direction.
  • the channels 20B-21B extend preferably along all the tunnel transverse width so as to blow air on all the fabric width.
  • each blowing device 20-21 has a flow baffle 20C-21C; this baffle is preferably in the form of a plate, hinged for instance in correspondence of the area where the air supply duct 20A-21A bifurcates into the two channels 20B'-21B' and 20B"-21B", and is designed selectively to close, through an actuator described below, one of the channels, thus cooperating in forcing all the air flow to move towards the opposite diverging channel.
  • the upper and lower blowing devices 20 and 21 convey air, in coordination with each other, according to inclined directions converging in a first feed direction (see figure 2 ) towards the second impact structure 17 and a second position, wherein the upper and lower blowing devices 20 and 21 convey air, in coordination with each other, according to inclined directions converging in a second feed direction (see figure 3 ), opposite to the first feed direction, towards the first impact structure 16.
  • the air flows coming from the channels 20B'-21B' or 20B"-21B" converge inclined on the fabric from the top and from the bottom, and impact the fabric. These flows are substantially balanced as regards both flow rate and incidence; therefore, the vertical components of the air push onto the fabric reciprocally cancel out, whilst the horizontal components add to one another, pushing/pulling the fabric along the path 11 towards the tunnel exit, until it impacts against a corresponding impact structure.
  • the pressurized air from the channels 20B'-21B' or 20B"-21B" is preferably sucked by respective inlets 23A and 23B, each connected to a branch of the further suction and recirculation circuit 14, so as to give the fabric T a further push.
  • This further suction and recirculation circuit 14 comprises two channels 24A and 24B connecting the inlets 23A and 23B with a compressor or fan 25 through gates 26 that can be opened alternatively according to the air suction direction, i.e. to the fabric feed direction in the tunnel.
  • the two channels 24A and 24B join together at a filter 27, from which a further channel 28 extends, crossing a heat exchanger 29 and achieving the compressor/fan 25.
  • An outlet 30 to eject part of the exhausted air is arranged between the filter 27 and the heat exchanger 29.
  • the compartments 20A and 21A are operatively connected with the outlet of the compressor/fan 25.
  • the fabric is driven by the air, exiting from the first channels 20B'-21B' of the blowing devices (and coming from the compressor/fan 25 through the ducts 20A, 20B), and moved from a first tank 18 towards the second tank 19, impacting against a respective impact structure 17.
  • the air flow is conveyed towards the second channels 20B'-21B' of the blowing devices 20-21, thus inverting the push direction, and consequently the feed direction of the fabric, which is pulled from the second tank 19 towards the first tank 18 impacting on the opposite structure 16.
  • figure 1 relates to a version with open-width fabric, but also processing fabrics in rope form, is disclosed therein.
  • the flow baffle 20C-21C of each blowing device 20 or 21 can characteristically take a third position, in addition to the two positions of closing the respective diverging channels 20B'-21B' and 20B"-21B".
  • the baffle In this intermediate third position the baffle is neutral, i.e. it does not close any respective diverging channels 20B'-21B' and 20B"-21B" ( figures 4 and 5b ).
  • the pressurized air from the compartment enters both the channels substantially at the same flow rate, and invests the fabric T, giving it a push with null horizontal component (i.e. the component, parallel to the tunnel inner extension, null), so that it remains stationary and does not impact against the impact structures.
  • the machine is configured so that the baffles of both the devices can move to the third position so that also the vertical resultant of the push on the fabric is null. In this step, the air exerts only a drying action on the fabric, without moving it towards the tanks.
  • the alternation of the impact between the grille-like impact structures 16 and 17 may be overlapped by a step of stopping the fabric (in addition to the step wherein the fabric inverts its motion), during which the fabric is invested by air for drying.
  • the frequency and duration of this stop depends upon the desired degree of dryness and/or the desired smaller number of impacts for the fabric; this allows an optimum flexibility of the machine, that therefore can be used with the broadest range of fabrics.
  • the machine is provided with moving means, for moving the flow baffle between the first and the second working position, and vice versa, passing through the third position but without stopping there, thus obtaining the reciprocating of the fabric motion, as well as with stopping means for stopping the flow baffle in this third working position for a given time, thus allowing to stop the fabric for drying it; whilst the moving means operate, the stopping means are deactivated, and vice versa.
  • the moving means and the stopping means preferably comprise the actuator 31, allowing the flow baffle to move; moreover, the moving means and the stopping means preferably comprise common electronic means designed to manage alternatively the stop of the flow baffle in, or its movement through, the third working position.
  • the electronic means may comprise adjusting means, not shown in the figure and controllable by an operator, for adjusting the length of time the flow baffle remains in this third position.
  • the electronic means may analogously comprise adjusting means, not shown in the figures, for adjusting the periodicity at which the flow baffle is stopped in this third position.
  • the adjusting means may comprise an electronic control associated with the actuator of the flow baffle, allowing the operator to set preset or desired values for periodicity and time of the stop.
  • the electronic control can be managed automatically by means of an electronic program that, based upon detected values (such as the fabric moisture level) can adjust the length of time and the periodicity of the stop of the baffle according to specific requirements.
  • the length of time the fabric is stationary is not instantaneous, and is preferably greater than 0.1 seconds, more preferably greater than 1 second, and more preferably greater than 2 seconds.
  • each flow baffle 20C-21C can be moved for instance through an actuator 31, like a translation cylinder (see figures 5 ), preferably of the pneumatic type, hinged at one end to the machine body and at the opposite end to the plate forming the same baffle 20C-21C, in particular in a position opposite to the closing portion of the diverging channels with respect to the axis of horizontal hinging of the plate to the machine structure.
  • the pneumatic cylinder is of the "tandem" type, i.e.
  • Each part has an inlet/outlet for the moving air of the piston 31D-31E.
  • the free end of the first stem 31F is hinged to the machine structure, whilst the free end of the other stem 31G is hinged to the respective plate-flow baffle 20C-21C.
  • an actuator 31 is shown related to the upper blowing device 20, the actuator and the connection to the corresponding baffle being analogous also for the lower blowing device 21 (the operation of the lower blowing device is synchronized with that of the upper device so that the air flows in the corresponding directions at the same instant and with equal flow rate).
  • the operation of the actuator 31 is as follows.
  • figure 5a the case is shown, wherein both the stems are completely retracted in the respective chambers (i.e. at start of stroke, from an operational viewpoint), and the pistons are against the wall separating the two coaxial chambers.
  • the plate 20C is inclined to close the diverging channel 20B' and the device can not therefore supply air towards the tank 18, so that the air flows in the diverging channel 20B" towards the tank 19 (the fabric moves towards this tank and the impact structure above).
  • the method according to the invention provides for pulling or pushing the fabric, through air flows at least below, but preferably also above the fabric, alternatively towards opposite impact structures 16 and 17, against which the fabric impacts.
  • the directions of these air flows are inclined relative to the horizontal, so as to create a resulting horizontal component of the air push or pull on the fabric that allows to move this latter.
  • these steps of alternating motion are alternated, according to a given periodicity, with a step of blowing, also called stop or floating step, wherein the resulting horizontal component of air push or pull on the fabric is null, wherein the air invests the fabric without moving it towards a respective impact structure.
  • This stop or floating step is distinct from and alternative to the step of inverting the direction of the air flows to invert the fabric motion.
  • the method may provide for: conveying air from below and above the fabric T according to two first inclined directions converging on the fabric, thus moving it against the second impact structure 17; stopping the air flow according to these two first converging inclined directions and conveying air from above and below according to two opposite second inclined directions converging on the fabric, thus moving it in opposite direction towards the first impact structure 16; the method then provides for stopping, under request, the movement of the fabric towards the first or the second impact structure 16, 17, conveying air from above and below contemporaneously according to the first and second inclined converging directions, thus making the push or pull on the fabric substantially null.
  • the stop or floating step may be provided after a certain number of reciprocating movements of the fabric between the two impact structures, or at each inversion, or also according to preset time intervals.
  • the length of time the fabric is stationary is not instantaneous, and is preferably greater than 0.1 seconds, more preferably greater than 1 second, and more preferably greater than 2 seconds.
  • this time is preferably comprised between 0.1 and 20 seconds, more preferably between 2 and 20 seconds, more preferably between 2 and 7 seconds, and more preferably equal to nearly 5 seconds.
  • the method of the invention may provide that the air flows, moving or floating the fabric, are arranged only below the fabric and not above. Consequently, in a simplified embodiment of the machine according to the invention, only the lower blowing device may be present.
  • the invention can provide an embodiment of this lower blowing device (but of the upper too) different than that proposed above.
  • a sliding or guillotine gate may be provided for each diverging channel.
  • one or more channels may be present with variable inclination, for instance as described in some embodiments of the patent application FI2008A000100 , with these channels able to take a vertical orientation to obtain an air flow on the fabric with substantially null push horizontal component.
