Definitions

  • the invention relates to a method and a system according to the preambles of claims 1 and 3.
  • carpet printing which is a preferred field of application of the invention, requires large amounts of printing paste. Even systems on which 5 m wide carpet webs are continuously printed, printing paste is used in an amount of up to 5,000 liters per hour. For reasons of color consistency, a relatively large batch of printing paste, which is sufficient for several hours of operation of the printing device, is often completed and kept ready. In general, the amount to be prepared beforehand is calculated in advance depending on the surface of the carpet web to be equipped, but it cannot be avoided in practical operation that certain amounts of prepared printing paste remain over and over again, which are then difficult and expensive to dispose of.
  • the invention has for its object to design a generic method and such a system so that the amount of remaining thickening is minimized.
  • thickening approach and color approach are kept separate and mixed only in accordance with the consumption of printing paste, so that there is not a previously completed, the total amount of printing paste approach, but the printing paste is continuously produced during the printing process according to the consumption.
  • the end of the printing process at any time be it immediately after the start, there is not a correspondingly large remaining amount of printing paste remaining, but at most the amount remaining in the work containers and pipelines just mixed printing paste.
  • a certain thickening approach is not lost when changing the pattern, but can be used with other color approaches. After all, it is not the total quantity that is produced before the printing process, but rather the quantity that is currently required for the printing process.
  • thickening batch is intended to mean an aqueous thickening solution which is adjusted to a certain viscosity below a certain pH.
  • paint batch stands for an aqueous paint liquor with all auxiliaries and chemicals. It can be mixed from several color solutions.
  • the two batches are mixed in doses, i.e. the quantitative ratio of thickening batch and color batch or color batches is regulated to a predetermined value.
  • a further development of the invention is the subject of claim 2, which states that not only the quantitative ratios can be set to a certain value, but also that the total amount of printing paste produced depends on consumption, i.e. is automatically regulated by the advance speed of the web to be printed. If the web runs faster, more printing paste is mixed together, if it runs slower, production is reduced.
  • Claim 3 reflects the apparatus aspect of the invention.
  • the system can comprise a regulating device for regulating the amount of the printing paste produced as a function of the speed of the web.
  • the storage devices for the thickening batch and the color batch are each assigned a circulation circuit with a changeover valve.
  • the circulating device arranged in the circulation circuit in the form of a pump with metering device can continue to run. If necessary, the thickening or paint batch is removed from the changeover valve or returned to the storage device after the changeover valve has been switched over. Fluctuations that could otherwise occur due to the pump starting and braking are not possible.
  • the respective storage device can comprise an actual storage container and a downstream intermediate container of lesser content, the filling of which can be controlled from the associated storage container by means of level sensors attached in the relevant intermediate container.
  • the purpose of the intermediate containers is to keep the amounts of thickening batch and ink batches that are to be handled for the production of the printing paste at the current time, which are to be discarded in the event of a pattern change, as low as possible.
  • the content of the intermediate container should be less than 200 liters (claim 7).
  • the circulation circuit should be formed on the respective intermediate container (claim 8).
  • the design of the circulation device can be designed according to claim 9.
  • the mixer it is possible for the mixer to be connected directly to the printing device.
  • the pressure device it may be appropriate for the pressure device to include a consumption container with at least two level sensors arranged one above the other (claim 10).
  • the level sensors can cooperate with the circulation devices on intermediate containers in the manner shown in claim 11.
  • the changeover valves of both the thickener attachment and the one or more paint attachments are switched to conveyance to the outside, so that the consumable container is refilled.
  • the upper level sensor is reached a renewed switchover of the switchover valves to circulation.
  • the supply device for the thickener approach is designated 10 and bordered with short lines
  • the supply device for the color approach is designated 20 and bordered with longer lines.
  • the storage device 10 comprises a storage container 1 for receiving a thickener attachment 2, which was produced in a separate thickener dissolving station, not shown, and was supplied to the storage container 1 via a line 3.
  • the thickening approach has e.g. a viscosity of 40,000 cps and a suitably chosen pH.
  • Via a conventional valve arrangement 4 at the bottom of the storage container 1 and a pump 5, the thickener batch is fed via the line 6 to an intermediate container 7, the supply being controlled via level sensors 8 in such a way that the intermediate container 7, which has a much smaller volume than the storage container 1 and contains, for example, 150 liters of thickener, always remains full.
  • the storage device 20 has two storage containers 11 and 11 'with color solutions 12, 12' and all the necessary auxiliaries and chemicals which have been fed through lines 13 from a separate color dissolving station, not shown. Instead of the two storage containers 11 and 11 ', only one storage container or more than two storage containers can also be present.
  • the color solutions 12, 12 ' reach a common line 19. When changing colors, this can be rinsed with water from a water connection 21.
  • a pump 15 arranged in the line 19 conveys the aqueous paint solution via a line 16 into an intermediate container 17, in which there are about 75 liters of an aqueous paint batch 13 mixed from the paint solutions 12, 12 '.
  • Each of the intermediate containers 7, 17 is one as a whole With 22 designated circulation device assigned, which comprises a pump 23 connected to the respective intermediate container 7 or 17, a downstream volume flow measuring device 24 and a switchover valve 25 connected downstream thereof, which selectively feeds the flow of the pump 23 into one of the intermediate containers 7 or 17 directs recirculating circulation line 26 or into a delivery line 27 leading into a mixer 30.
  • the delivery lines 27 are thus connected together to the mixer 30, water being able to be added if necessary from a water connection 28.
  • the mixer 30 may be a static mixer with internal baffles, in which the mixing of the components takes place during the flow. The one at the outlet of the mixer
  • the consumption container 31 serves as a buffer container between the printing device and the upstream system parts for providing the printing paste. It becomes the level of the print paste 33 in the consumption container
  • the changeover valves 25 are switched over and direct the amounts of thickener batch 2 or paint batch 13 continuously and evenly conveyed into the lines 27, which lead to the mixer 30, by the pumps 23 .
  • the consumption container 31 is thereby filled with pressure paste 33 until the upper fill level sensor 38 "is reached.
  • the changeover valves 25 are switched over again and now direct the delivery flow of the pumps 23 via the circulation lines 26 into the intermediate containers 7 and 17 back.
  • the consumption container 31 thus remains constantly filled to a certain extent.
  • This control is implemented in a similar manner on the intermediate containers 7 and 17 by the level sensors 8 and 18 there.
  • the printing paste 33 must contain the thickening formulation 2 and the coloring formulation 13 in a certain constant ratio for all total delivery quantities. For this reason, the delivery rates of the pumps 23 are regulated by means of the volume flow meter 24.
  • the signals from the volume flow meter 24 reach a control device 40, which in turn acts on the pumps 23.
  • the total amount currently required, i.e. the production of printing paste 33 can be set manually on the control device 44 if the demand is reasonably constant.
  • the thickening approach 2 and the color approach 13 remain separate from one another up to the mixer 30.
  • the printing paste 33 is only produced in the mixer 30.
  • the collecting container 39 channel
  • the main quantity - thickener batch remain in the intermediate container 7 and storage container 1 and are not affected by a change.
