Definitions

  • the present invention relates to a device for applying a liquid, in particular water, to a moving substrate and a method for implementing said device.
  • Machines are already known for spraying liquids on a moving substrate, for example water on a fabric to allow it to be stretched.
  • the documents US 5795391 and US 2002/100415 describe apparatuses for applying fluid materials to moving surfaces. These devices use to project the fluid of the rotating disks, the liquid being thrown by the centrifugal force. Most known machines use this principle rather than nozzles, the latter having orifices of small diameters easily clogging.
  • Spraying by centrifugal force produced by rotating discs for spraying large quantities of liquid onto a moving web is known, for example in the publication "Zerstäubungstechnik, ISBN 3-540-41170-4, page 82".
  • Another object of the invention is to provide a simple, inexpensive and reliable device.
  • the first criterion ensuring the aims of the invention is achieved by the new liquid distribution technique on all the rotors of the device.
  • Each rotor is fed by a container providing a constant and identical hydrostatic pressure for each rotor, a pump fills the containers of each rotor.
  • a schematic section of a rotor for a device according to the invention has two parallel disks 7 and 8 arranged to rotate about the same vertical axis 17.
  • the disks 7 and 8 are disks consisting of a flat surface, for example the kind of the one defined in the patent CH 699527 they can be made of metal or of flexible synthetic material.
  • the discs have a diameter of between 60 mm and 100 mm, preferably 70 mm.
  • the disc 7 is fixed on a rod 13, with a diameter of about 4 mm, disposed inside a tube 18, of diameter about 10 mm so as to be able to rotate independently of said tube 18.
  • the disc 7 is fixed by suitable means, for example O-rings 1 and 2 on the rod 13.
  • Said rod 13 has ball bearings at its upper part 14 and its lower part 9.
  • the disk 8 is fixed on the tube 18 in the same manner as the disk 7, that is to say with O-rings 3 and 4.
  • the tube 18 is mounted in a support block 16 fixed to said block by ball bearings 10 and 11.
  • the tube 18 further has a disc 19 disposed above the disc 8 on the figure 1 , and said disk is fixed on said tube 18 by O-rings 5 and 6.
  • the tube 18 comprises at its upper part a pulley 15 placed above the support block 16, and the rod 13 also has at its upper part a pulley 12. It is easy to understand that those skilled in the art, these arrangements allow, by passing belts on the pulleys 12 and 15, to rotate the discs 7 and 8 in different directions.
  • the figure 2 represents a schematic longitudinal section of a set of four rotors with vertical axis arranged on a support beam 26.
  • a device according to the invention will always have a succession of three rotors as shown on the left side of the figure 2 . That is to say starting from the left on the figure 2 , a first rotor having two disks 7 and 8 an upper and a lower, followed by a second rotor also having two disks 7 'and 8' an upper and a lower arranged so that the disk 7 'comes to rotate between the disks 7 and 8 of the first rotor and that the disk 8 'rotates above the disk 8, followed by a third rotor also having two disks 7 "and 8" an upper and a lower arranged so that the disks 7 "and 8" rotate between the disks 7 'and 8' of the second rotor.
  • a device comprises a succession of rotors as defined above fixed on a support beam 26, according to one embodiment it is provided between 17 and 20 rotors per meter.
  • the axes of the rotors are 56 mm apart and the diameters of the discs are 70 mm,
  • the supply tubes of the first rotor comprising the discs 7 and 8 are indicated by 25 and 27, see figure 3 .
  • the set of rotors is fixed on a support beam 26 by means of blocks 16, and is enclosed in a housing 20 for collecting the surplus liquid.
  • each rotor has a independent supply tank 34, as shown in figure 4 .
  • the rotors are arranged behind a plate 21 having openings (see figure 5 ) so as to allow the sprayed and sprayed liquid to reach the substrate through the opening 20a of said housing 20.
  • the openings in the plate 21 are calculated to limit the width of the projections.
  • the plate 21 has an opening, for example for the disk 7, the opening is the opening 21 7 while the opening 21 8 is for the disk 8. It can be seen that in front of each rotor there are two openings, in this embodiment it provides six openings in the direction of the height, which ensures a more even distribution of projections.
  • the part 24 containing the rotor supply tanks is fixed by bolts 31 to a support piece 32 itself fixed to the support beam 26.
  • the piece 32 is pierced with holes corresponding to the feed tubes 25 and 27 of the disks 7 and 8, the same for all other rotors.
  • a plate 35 Between the piece 24 and the support piece 32 is disposed a plate 35, which can move smoothly friction longitudinally relatively to following the rotors.
  • the plate 35 is held vertically by pins 30, arranged in oblong openings.
  • the plate 35 has holes, which have the same diameter as the tubes 25 and 27, so it is possible to control the flow rate in said tubes by opening or closing said holes by the displacement longitudinal of the plate 35. It is the same for all the rotors.
  • the displacement of the plate 35 will be controlled, for example, by a stepper motor (not shown).
  • a stepper motor There are provided electronic devices (not shown because within the reach of those skilled in the art) to control the projection of each disc.
  • the openings 36 are in contact with such devices.
  • devices for adjusting the flow of each rotor by independent means for each rotor.
  • the plate 35 would be replaced by plates arranged facing each rotor and hinged perpendicularly to a pin, each plate being controlled by a jack or a stepper motor
  • This safety device is constituted by a jack 23 intended to actuate a shutter 22 arranged in front of the openings of the plate 21.
  • FIG 6 schematically an image of the projections of liquid on the substrate S, according to the apparatus of the firm Consultex Corporation described in the patent, has been schematically represented.
  • US 5795391 The rotors, according to Consultex, act in a plane inclined relative to the vertical, each rotor having only one disc. It is found that the distribution of the liquid on the substrate is not uniform, and the amount of liquid is relatively low.
  • FIG 8 schematically shows the result of a device according to the invention employing rotors having two disks rotating in the opposite direction on the same vertical axis, and comprising a succession of sets of three rotors each having two disks at different heights, the discs of two adjacent rotors overlapping.
  • the substrate S which has a shorter width than the The length of the set of rotors receives a much larger and more uniform amount of liquid than in the Consultex apparatus.
  • the invention provides a device that is effective and easy to produce, and therefore less expensive than known devices, for treating moving substrates, especially fabrics by liquid spraying.
  • a device according to the invention can be combined with any device within the reach of those skilled in the art, for moving a substrate in front of a row of rotors.
