Definitions

  • the invention relates to a device for evenly distributing fluids, such as liquids, by means of, for. B. a paint applicator, with which this paint is in a uniform, distributed over a working width liquid layer on a leading textile or the like.
  • a. Consisting of a distribution container receiving the liquid to be distributed with a central inflow and several liquid transport channels, such as hoses, which emerge from this distribution container at outlet openings and start in the region of the circumference and extend to the application device for generating the liquid layer, the distribution container being closed on all sides, only is provided with the inlet and the outlet openings, circular hollow plate which is filled with the liquid via its inner volume, and in the cavity alone a radially directed liquid flow, which delays towards the outlet openings, arises
  • a device of this type is known from DE 40 38 359 A1 (preamble of claim 1). It has the advantage that the liquid to be distributed from a central inflow point over a large working width of the inking device not only takes place uniformly, but that the liquid flow in this distribution device is slowed down uniformly for all outgoing points. This is the prerequisite for a consistently even application of paint to the respective width of the textile goods.
  • a paint applicator is generally built for a certain working width.
  • the incoming textile webs vary in width, possibly even at short notice. It is the task of the machine manufacturers to supply dyeing devices with which different working widths can be run at short notice.
  • the limitation of the working width in The area of the liquid drain on the paint applicator cannot be solved satisfactorily. This applies in particular to the uniformity of the amount of paint applied in the edge area of the textile material.
  • the invention provides for a device of the type mentioned initially, at least a part of the circularly arranged drain openings assign a valve to close the flow cross-section. Care must be taken to ensure that the uniform removal of the liquid from the distribution container remains unchanged. This is advantageously possible if individual drain openings are not made closable, but it is expedient that the drain openings are arranged in two circular rows on the hollow plate and that one, preferably the radially inner row, is provided with valves for closing.
  • a large number of drainage points must be provided on the distribution container; there must be a large number of liquid transport channels so that the assigned paint application device is supplied with the necessary amount of liquid evenly over the working width and the desired working width can also be set exactly.
  • the number of channels required that is to say liquid drain points together with space-consuming hose nozzles in the case of hoses and the like, determine the diameter of the distribution container. It is now possible to provide drainage openings on both sides of the plane of the plate, but the number of hoses can nevertheless require an undesirable size of the diameter of the plate. In addition, care must be taken to ensure that all drain openings on such a distribution container are supplied with exactly the same amount / time unit of color liquid.
  • This construction initially has the advantage that the flow threads can form undisturbed when the discharge openings are arranged opposite one another. Furthermore, in order to influence the uniform outflow of the liquid, care should be taken to ensure that the liquid builds up in front of the respective outflow opening. This is achieved by a constant reduction in the flow cross sections of the flow channels in the distributor plate and also by small flow openings at the end of this flow channel compared to the cross section of the flow channel.
  • a connecting channel extending to the drain openings connects to the ends of the flow channel or from the respective flow opening. In any case, this is directed radially, but can also be directed in the circumferential direction in order to achieve a further distribution of the liquid in the plate.
  • These connecting channels which are of course arranged parallel to the flow surface in the hollow plate, enable a larger number of liquid transport hoses to be accommodated on the circumference of the distribution container without the diameter of the distribution container becoming too large.
  • no dead corners or channels are possible if one or the other liquid transport hose has to be switched off in order to influence the active working width of the application device.
  • the closure then takes place at the flow openings of the flow channels by means of valves arranged on the plate, the closing needle of which simply blocks the flow of further liquid into the associated connecting channel. In this way, too, there are no spaces in the distributor in which there is liquid.
  • a distribution device is available with which the necessary, exactly the same amount of liquid can optionally be supplied to a large number of hoses in a small space. At the same time, it is easy to clean.
  • the distribution container is designed as a hollow plate 1. It is circular and has two circular walls 2, 3 or with 2 ', 3' according to FIG. 5, which are arranged at a distance from one another and are connected to one another radially on the outside in a liquid-tight manner.
  • 2 ' opens centrally an inflow pipe 4, which ends at this wall 2, so does not protrude into the cavity 5 of the hollow plate.
  • the diameter of the tube 4 is larger than the clear height of the cavity 5.
  • bores 6 are arranged in the wall 2 or 2 ′ as well as in the wall 3 or 3 ′ as outflow openings uniformly distributed over one and the same diameter.
  • a hose nozzle 7 is screwed or otherwise attached to the in each case a hose is pushed on, which feeds the flowing fluid to the correspondingly defined area of the paint applicator.
  • a second circular row of flow bores 6 ′ is provided in the wall 2 on the outer edge, all of which are supplied with the valve 8.
  • the valves 8 are fastened in the opposite wall 3 and protrude with the closing needle 9 first through the cavity 5 but then into the flow opening to be closed.
  • all other common valves e.g. B. also those that have the closing valve in the mouthpiece itself, can be installed in the device.
  • This distribution plate is therefore designed for two working widths. If several differently smaller working widths are to be controllable on a paint applicator with a large maximum working width, the device according to FIG. 4 lends itself, in which the inflowing liquid is first halved on a T-shaped branch line 10, then to the right and left in each case a device to run, as shown in Fig. 1. This means that three working widths can be optimally supplied with the necessary liquid.
  • a flow channel 11 adjoins radially on the outside around the plate-shaped cavity 5.
  • This flow channel 11 can consist of several bores extending perpendicular to the plane of the cavity 5 or, according to FIGS. 6 and 7, consist of a cylindrical flow channel 11 around the cavity 5.
  • the two legs 11 'and 11 "are of the same length, so that the flow channel 11 adjoins the cavity 5 in a T-shape.
  • the cross section of which is already reduced compared to that of the cavity 5 there are flow openings 12, 7 and are used not only to build up the liquid to be distributed, but also to close the connecting channels 13 with the outlet openings 6 provided at the end the flow channel 11 is completely open, that is to say cylindrical, starting from the flow openings 12, the adjoining connecting channels 13 and the outflow openings 6, individual stream threads, each of which supplies a liquid distribution hose which is put over the hose nozzle 7 with the necessary liquid.
  • the connecting channels 13 run parallel to the plane of the cavity 5. They extend according to FIG. 7 following the flow channel 11 or the flow openings 12 radially outwards.
  • the connecting channels 13 offer space for the arrangement of valves 8 adjoining the axis, which are screwed into corresponding bores in the wall 2 'or 3' relative to the flow openings 12.
  • the valves here consist of pressure piston-cylinder units, the pistons of which end in a closing needle 9, which can close the respective flow opening 12. If the needle 9 penetrates through the connecting channel 13 into the flow opening 12, the inflow of the liquid into the connecting channel 13 is blocked at the same time, so the liquid is not in the channel 13 and thus not in the liquid transport hose, provided that the applicator is first the narrower working width starts to work. 6, only four pressure piston-cylinder units are provided in the exemplary embodiment, so that four, ie 25%, of the twelve hose mouthpieces can be closed with the associated hoses.
  • FIGS. 8-10 is similar to that according to FIGS. 5-7, it is designed according to FIG. 9 only for more liquid distribution hoses. Therefore, there are initially more flow holes 12, namely instead of twelve now fifty-two pieces in the escape of the flow channel 11 is arranged, and in turn, each flow bore 12 is followed by a connecting channel 13, which is directed around the flow channel 11 according to FIG. 10 alternately once radially outwards and once radially inwards. Eight pieces of pressure piston-cylinder units 8 for closing the flow openings 12 are provided here, but the number can easily be increased. In this way, a significantly larger number of liquid transport hoses can be connected to a distributor. Of course, the number of liquid transport hoses mentioned only applies to one side of the distributor, the same applies to the other.
