Definitions

  • the invention relates to a device for applying a laminar flowing liquid film which is uniformly thin over the working width to a continuously advancing web with a liquid-fed device fed by a pump with a liquid distribution space and an associated guide surface, possibly connected via an overflow weir, the lower of which Edge of the flowing liquid film runs onto the material web, the liquid distribution space being connected to the pump on the one hand via an inflow line and on the other hand extending to the guide surface over a working width which is larger than the cross section of the inflow line.
  • a device of this type is known from DE 35 22 320 A1. It has the advantage that with this device a quick change of the application liquid by type or color is possible without the associated loss of production or rejects of the web to be wetted, a uniform distribution and a constant amount of the application liquid being ensured over the working width. This is brought about by a liquid storage space upstream of the overflow weir, which opens conically towards the overflow weir, but is at least small in volume. In this way, the calming of the liquid feed stream necessary to form a laminar liquid film is achieved up to the overflow weir.
  • the calming of the liquid feed flow is necessary in such a device because the liquid volume within this liquid storage space is only very small, but the amount of liquid applied over the working width of more than 30 1 / min / m of the working width is very large and thus the inflow of the liquid is distributed into this device is very strong over several inflow lines.
  • a liquid distribution space is arranged in front of the liquid storage space, which extends over the entire working width as well as the overflow weir.
  • the inflow lines are assigned to the liquid distribution space.
  • the liquid flowing in through these lines is distributed over the working width in the distribution space by several baffles or baffle walls.
  • the invention has for its object to develop a device with which the line of color change is now possible with the same area of responsibility for rapid color change and a low liquid volume in an application device with the advantageous pouring principle and thereby still reduce the previously required liquid volume within the device can be.
  • the solution to the problem is that the liquid distribution space extends only over a precisely defined working width, which is only narrow compared to the width of a wider web, and this space is connected to only one liquid inflow line. Since this area of work is a device that has to pour the liquid over a web with a larger working width, a large number of these liquid distribution spaces are arranged side by side, which then only cover the entire working width of the web. It is therefore the aim of the device according to the invention to calm down and laterally distribute the liquid flowing in through the inflow line already in the limited liquid distribution space cause, in such a way that when changing colors there are no streaks of mixed colors in order to allow the liquid to flow directly to the overflow weir or better to the guide surface after this even distribution. It is then possibly no longer necessary for the calming space still required according to the aforementioned publication, so that the volume of liquid required in the application device can be kept considerably lower.
  • a particularly advantageous way of designing the liquid distribution space with the branch tree-like branching of the liquid from the inflow line to the multiplicity of liquid outlet openings is that the branch lines extending in the working width direction and the intermediate outflow openings adjoining the end of this branch line are in the form of holes can be introduced in correspondingly thin sheets. It is therefore particularly advantageous to fill the liquid distribution space with a large number of such sheets and to arrange the branch lines and holes to be produced in these sheets according to a certain program in such a way that there is a uniform, family tree-like branching of the lines from the inflow line to the large number of outflow openings that the overflow weir or equal are assigned to the baffle.
  • the liquid application device consists of a carrier 1, the 90 ° corner of which is oriented upwards.
  • One leg of the angle bracket is the baffle wall 2, which is oriented obliquely upwards in the direction of the overflow weir 3.
  • the overflow weir 3 is followed by the guide surface 4, via which the uniformly distributed liquid film runs off and flows onto the web 5 running underneath.
  • the web 5 is carried with a pile arranged upwards over a deflection roller 6.
  • a solid body 7 is arranged, the wall of which is associated with the baffle wall 2 serves as a diffuser wall 8. This wall 8 can also be aligned parallel to the storage wall 2, so that a slot 9 'is formed as a storage space.
  • the storage space 9 which widens conically to the overflow weir 3, is formed.
  • the storage space can, however, also run in the form of a slot without a cone, as shown in FIG. 5.
  • the body 7 extends with the remaining parts of the paint application device 1 over a working width of one to six meters and is only provided with a few inflow hoses 10 over this working width, via which the required amount of liquid flows to the application device with a pump, not shown.
  • the device shown corresponds to that of DE 35 22 320 A1.
  • liquid distribution system which is arranged in the body 7.
  • the hose 10 is placed over a mouthpiece 11 which is held in the body 7 in the area of the reference number 12 and is screwed with its lower end into the so-called liquid distribution device 13.
  • the liquid distribution device can also be oriented perpendicular to the baffle wall 2 and not parallel to the baffle wall - as shown in FIG. 5.
  • This liquid distribution device 13 is shown in detail in FIGS. 2 and 3. It consists of a plurality of sheets 14 which are arranged parallel to each other and pressed together after assembly. In the uppermost plate 15 of this liquid distribution device 13, only one hole is drawn, which forms the liquid inflow opening 16 of a liquid distribution space of limited working width according to FIGS. 2 and 3.
  • a liquid distribution system extends from each of the liquid inflow openings 16 to the lower side of the individual liquid distribution device 13, which extends over an exact working width, but which is only a fraction of the total width of the application device.
  • the distribution of the liquid flowing in through the inflow opening 16 takes place in the liquid distribution space which is filled by the individual sheets 14.
  • this distribution space has eight sheets 14 arranged parallel to one another, which results in a distribution of the liquid flowing in through the inflow opening 16 over a total of sixteen liquid outflow openings 17. This is achieved in that the distribution of the liquid width from sheet to sheet is gradually forced.
  • branch lines 18, 19 of equal length are arranged on both sides of the liquid inflow opening 16 in the working width direction - according to FIG. 2 both to the right and to the left - an intermediate outflow opening 20, 21 is provided at the respective end of the latter.
  • These two intermediate outflow openings 20, 21 are drilled in the plate 14 arranged underneath.
  • the liquid distribution device is formed from a plurality of sheets 14 arranged parallel to one another, each of which has either an intermediate outflow opening 20, 21 or a branch line 18, 19, 22, 23.
  • the bores 20, 21 and, as elongated holes, the branch lines 18, 19, 22, 23 are introduced at such points in the individual sheets that this branch tree-like branching according to FIG. 2 results after assembly.
  • the division of the entire working width from 1 to 5 m into areas which correspond to a liquid distribution space shown in FIG. 2 has the advantage that the liquid supplied through the areas 10 can be distributed exactly uniformly over a large working width.
  • the more important advantage, however, is to achieve the compulsorily uniform distribution of the liquid over the working width without having to use a common storage space which extends over the working width.
  • Those from the liquid outlets 17 Evenly emerging liquid only accumulates in the connecting gap 24 which now extends over the entire working width of the web. A dynamic pressure arises there because this connecting gap 24 is followed by a liquid outlet gap 25, which also extends over the working width and whose flow height is smaller than the depth of the connecting gap 24.
  • the liquid comes out of the liquid distribution device 13 from the liquid outlet gap 25, distributed uniformly over the working width.
  • the liquid storage space 9 shown in FIG. 1 is only necessary to a limited extent.
  • the liquid distribution device 13 is only assigned a guide surface in the form of a guide plate 27, through which the liquid distributed by the liquid distribution device 13 over the working width runs to the web 5.
  • the connecting gap 25 can be formed in a simple manner between this last plate 26 with the connecting gap 24 and the guide plate 27.
  • not only the solid body 7 with the liquid storage space 9 is omitted, but also the overflow edge 3 together with the angle bracket 2, rather only the guide plate 27 is required to drain the uniformly distributed liquid onto the material web 5.
  • the volume of liquid which is always filled in the distribution device 13, better even in the application device as a whole, is considerably reduced, which enables the desired rapid color change.
