Definitions

  • the invention relates to a method according to the preamble of claim 1 and a corresponding system according to the preamble of claim 5.
  • a generic method and such a system are known from DE 43 05 438 Cl.
  • the components required to prepare a treatment liquor are metered from a plurality of storage containers to a distributor head, from which the components are discharged into collecting containers, from which they reach intermediate containers in which mixing devices are arranged.
  • the number of components mixed therein to the treatment liquor is metered from the intermediate container to the treatment stations.
  • the respective component is dispensed from the storage container in question into the collecting container until the amount required according to the recipe is reached. It can the case thus occurs that the component in question runs out longer than another component of the treatment fleet to be produced from the outlet point of the one storage container in the distributor head.
  • the invention is based on the object of designing a generic method and such a system in such a way that no difficulties arise in the preparation of even small amounts of uniformly mixed treatment liquor. This object is achieved in its procedural aspect by the invention reproduced in claim 1.
  • the invention can already be implemented if only one treatment station has to be loaded for which only one treatment liquor has to be able to be produced. Then only the components for this one treatment liquor are brought together at the same time in the recipe-related quantity ratio.
  • the preferred embodiment which is more important in practice, provides for the loading of several treatment stations with different treatment fleets. It is then the procedure for each individual treatment fleet as it is for only one existing treatment fleet. With the different treatment fleets, the different components are then just in the corresponding formulations
  • the total amount of the components required for a specific treatment liquor can also be controlled, and in particular while maintaining the recipe-related quantitative ratio for each total amount. In this way, it is adapted to consumption.
  • the time required for the treatment liquor can be very different, which can be set by the control in question.
  • Another step is the automatic regulation of the total quantity according to claim 4.
  • the total quantity according to claim 4.
  • Treatment fleet consumption determined in a foulard are when the web-shaped textile material in the pair of squeeze rollers is squeezed to a predetermined moisture content.
  • the squeezed treatment liquor runs back into the trough of the foulard, and it can thus be determined how much treatment liquor is required to maintain a certain level in the treatment trough.
  • the apparatus of the invention is the subject of claim 5.
  • Claim 6 reflects the extension to several treatment stations.
  • Storage container connected. It has a number of exit points equal to the number of storage containers. If there is only one treatment station with a specific treatment liquor, a number of outlet points of the distributor head which corresponds to the number of components of this one treatment liquor is sufficient. If, however, a plurality of treatment liquors are to be produced for a plurality of treatment stations, the distributor head has a correspondingly enlarged number of exit points, of which only those are opened during the production of a specific treatment liquor which bring in the components required for this specific treatment liquor.
  • the intermediate containers assigned to the various treatment stations are brought into alignment with the distributor head one after the other. As such, a relative movement between the intermediate containers and the distributor head is sufficient.
  • the preferred embodiment according to claim 9 is the movement of the intermediate container, be it as a rotary movement or as a linear movement.
  • the procedure is such that the individual intermediate container is supplied with so much total amount of components in their recipe-related quantity ratio that the demand can be covered from the intermediate container for a certain time.
  • the distributor head then serves the other intermediate containers. If the fill level in one of the intermediate containers falls below a certain level, which is dimensioned such that in any case there is no interruption to the supply of the treatment station, this intermediate container is replaced by the
  • the supply head is supplied with an inflow of all components at the same time in the recipe-related quantity ratio until an upper fill level is reached.
  • a system according to the invention is shown schematically in the drawing.
  • the system designated as a whole by 100, comprises a series of storage containers 10 for the components of all treatment fleets. In the schematic representation, only two such storage containers are shown completely, while in practice, when several, e.g. four treatment stations are to be loaded to handle thirty to fifty such storage containers 10.
  • Each storage container 10 is connected via a filter 1 and a metering pump 2 to a line 3 which leads to a distributor head designated as a whole by 20.
  • the line 3 opens into a 2-way valve which, in a first position, the line 3 with a short supply line 5 to an outlet element
  • Return line 8 connected at a point 9 between the filter 1 and the metering pump 2 in the feed line to the Dosing pump 2 opens.
  • the metering pump 2 thus runs continuously and either delivers its delivery rate via the supply line 5 at the assigned outlet point 7 or allows it to circulate via the lines 3 and 8. When switching over, there are no pressure surges that could distort the dosage. There are also no start-up problems.
  • the arrangement of elements 1 to 9 is present for each of the approximately thirty to fifty storage containers 10 of the system 100. A corresponding number of valves 4 must be provided. Because these valves are significant
  • valves 4 are rather arranged separately and connected via the short feed lines to the outlet element 6, in which the outlet points 7 can be arranged close to one another in plan view.
  • the intermediate containers 30 are each connected via a flexible line 11 to a quantity-controlled pump 12, the outputs 13 of which lead to the supply line to the respective one
  • Treatment station are connected.
  • the lines 11 are movable because the four intermediate Container 30 of the embodiment are arranged on a common base plate 14 which can be shifted in such a straight line by a drive shown only by the arrow 15 that an arbitrarily selectable intermediate container 30 can be brought under the distributor head 20 one after the other. It goes without saying that a rotating arrangement could also be chosen.
  • Each of the intermediate containers 30 has a fill level sensor 16 for a lower fill level and a fill level sensor 17 for an upper fill level. This is only indicated in the intermediate container 30 on the left in the drawing.
  • the base plate 14 is displaced such that the intermediate container in question passes under the distributor head 20 and the components resulting in the corresponding treatment liquor are refilled until the upper fill level is reached, whereupon the inflow is stopped.
  • the system is controlled by a control device 40.
  • the control device 40 contains a memory part in which the recipes for the individual treatment liquors are stored.
  • control device 40 The most important function of the control device 40 is to control the metering pumps 2 in such a way that they always convey the components from the storage containers 10 that are required for the treatment liquor of a particular treatment station in the ratio of the quantities required for the formulation.
  • mass flows of the individual components are thus simultaneously conveyed during the loading time, the ratio of which corresponds to the recipe at any moment.
  • the valves 4 responsible for these components are opened and closed or reversed at the same time.
  • control device 40 controls the total quantity of components dispensed per unit of time in their recipe-related temporal quantity ratio. No matter how much in total an intermediate container 30 per unit of time, the recipe is always followed.
  • the control device 40 also controls the start and the end of the loading of an individual intermediate container 30 via the sensors 16 and 17. When the upper sensor 17 is reached, all valves 4 involved in the treatment fleet concerned are switched over to circulation. The delivery of components from the exit points 7 stops suddenly.
  • the drive 15 for the selection of the intermediate containers 30 to be loaded can also be controlled by the control device 40, although manual control would also be possible in this respect.
  • the system can therefore cope with a very different need for several treatment stations running in parallel.
  • the sensor control of the fill level of the intermediate container 30 can be dispensed with under certain circumstances if the total quantity of the components supplied by the metering pumps 2 corresponds exactly to the consumption per unit of time. Then the components run continuously in the relevant intermediate container 30 and become the same without changing the level in the respective one
  • Means for mixing the components can be provided in the intermediate containers 30 in the usual manner.
