Definitions

  • the invention is in the field of textile technology and relates to a method for jointly controlling setting means on one or more interrelated flock opening and fiber cleaning machines, and an apparatus for carrying out the method.
  • the flake dissolving and fiber cleaning functions in textile cleaning machines are controlled by means of variable parameters, according to the values of which appropriate setting means are set during operation of the machine, if possible in such a way that no machine parts (tools) need to be replaced.
  • Such settings according to the parameter values can either be made manually and remotely via a corresponding actuator (e.g. a dial), showing the position of a value or value related to the setting, or automatically using a suitable actuator.
  • the parameters for the bale hardness are, for example, the depth of penetration of the removal roller per pass, the protrusion of the individual toothed discs of the removal roller from the associated grate, the speed and Removal devices with two rollers, the penetration depth of the individual roller, that is, all "setting values" for realizing any or more of these mechanical means.
  • these parameters concern For example, the distance of the individual grate bar to the imaginary outermost circumferential surface of the firing pin on the cleaning roller, the angular setting of the individual grate bars and the distances to the circumference of the firing pin and the angular position of the grate bars relative to one another, the speed of the cleaning roller and the suction intensity of the amount of air extracted by the screen plates .
  • the parameters of a fine cleaning machine, in which intensive flake dissolution takes place are, for example, the distance between the clamping point and the takeover point on the feed roller, the distance from the knife edge to the impact circle, the displacement of the guide plate to the knife, and the speed of the opening roller and, if necessary, the tip density, if this exists Tips can be changed by adjusting (and not only by replacing).
  • a fine cleaning machine In the case of a fine cleaning machine, for example, it has settings on machine elements which mainly affect the intensity of the cleaning, and therefore also the mechanical stress on the fibers.
  • This is, for example, the distance P4 in Fig. 6, i.e. the distance between the clamping line on the feed trough and the take-over line of the clothing of the opening roller, which distance P4 is set depending on the fiber provenance.
  • the distance d (FIG. 5, designated P7 in FIG. 6) of the separating means (knife) to the impact circle of the clothing of the opening roller.
  • the tip density z of the carding element and the speed n of the opening roller This means cleaning under stress on the fibers with as little loss of fiber as possible.
  • these two groups of parameters differ in the following characteristics.
  • the majority of one parameter influences the mechanical load on the fiber, which is proportional to the cleaning intensity. The more intensively cleaning is carried out, the more fiber damage occurs. This gives you the choice between fiber load and degree of purity.
  • the majority of the other parameters influence the output from the fiber material, which is proportional to fiber losses (even if recuperation should take place later in another cleaning cycle). This results in the compromise between the degree of purity with fiber loss and the degree of purity with fiber stress.
  • the operator Before the cleaning process begins, the operator has the choice of achieving the desired degree of purity with more fiber loss or with more mechanical damage, and during the process, depending on the result, he can use only two, control elements controlling the overall actuation can be changed at any time. In a further expansion stage, these two operating elements can also be activated via a computer control, the computer also selecting the "tables" from the library, fetching them and setting the operating elements. As already mentioned, this makes it possible to easily master very complex, machine-functional relationships through such pre-networking.
  • the adjustable functions on a machine or a networked machine group can be manipulated in a higher-level manner as follows: Groups of setting means are combined according to a "jointly acting" function.
  • the setting variables of these setting means are entered as parameters in a table, for example in the column of a table.
  • Vectors are formed from the rows of the table (or columns), which are given reference numbers. This gives you a number of Indicators, which are arranged according to the effectiveness of the common function.
  • These tables (with their vector set) can be linked together to form a higher-level function depending on their respective function.
  • a function formed from two tables defines a two-dimensional parameter field, with three tables it is three-dimensional.
  • Fig. 1 shows such an abstract representation of two tables T1 and T2, which represent two parameter groups M1, M2, M3 with one characteristic and P1, P2, P3 with the other characteristic.
  • the parameters are arranged in the table column.
  • the table rows, each with a value x of all parameters involved in a table, form the parameter vectors, which, in the order in which they appear in the table, are mapped onto an axis of a diagram f 1 and f 2. Since it is a networked system (either a machine or a machine group), these axes can be understood as variables or better as functions that are functionally dependent on each other.
  • this is symbolically represented by a group of parameters f2 (f1).
  • the crossing points of the parameter vectors of both axes form a matrix of operating points of the machine or machine group and thus define a parameter field or operating point field within which any position can be selected with the aid of a setting of f 1 and f 2.
  • This with the setting of only two sizes, namely the vector parameters of one and the other group or table. No other working points can be set outside the given working point field; the field delimits all sensible or possible settings in connection with the tables used.
  • Such parameter groupings i.e. the determination of the values x, are determined once (for example at the very beginning of a task for the machine) by means of test series on the machine or a machine type or a machine group.
  • the results of the different parameters i.e. the setting parameters on the machine, are defined once so that a cleaning program can be created from them, by means of which the brightness (the lighter the more good fibers in the outlet) of the outlet composition and the cleaning intensity (the more intensive the more fiber damage possible) is primarily selectable.
  • the tables in FIGS. 2 and 3 show such an example. This is a proposal for the grouping of group parameters and finally for the formation of a two-dimensional map which frames the adjustable operating conditions, it being irrelevant whether the setting is manual or by means of an actuator system is performed.
  • the tendency of the changes in the discharge quantity and their composition and a rough relative change factor of the discharge quantity are known as empirical values. However, this does not say about the absolutely excreted amount (it can vary by factors up to 40 and more), nor about the change factor the composition (which is highly dependent on the material) and the absolute composition of the waste quantity.
  • the criterion for forming a first group of setting parameters is the cleaning intensity (table Fig. 2).
  • the values of the higher intensity are at the top of the column, the intensity becomes weaker at the bottom.
  • the criterion for forming a second group of setting parameters is the exit (table from FIG. 3).
  • the table shows two columns with the boundary values of two different parameters P31, P32: displacement s (mm) from guide plate to knife from 0 to 5 (P31); Length l (mm) of the Elimination gap from 15 to 30 (P32).
  • the line assignments from 1 to 6 correspond to outgoing vectors with two parameter values. They can be called outgoing vectors, the outgoing vector with the assignment 6 having the largest outgoing value and that with the assignment O having the smallest.
  • the two group parameters then each form a group of setting parameters (setting process) with which the cleaning intensity is influenced and with which the finish can be influenced.
  • Each group has a set of adjustment vectors, which are determined in test series. The arbitrary assignment of two setting vectors from one group each gives a working point within the entire cleaning program, which can be set with only two setting devices.
  • Such a "cleaning program” is shown here in the diagram of FIG. 4.
  • Such a diagram can be created either for a machine, or for a machine group, or for an entire system, whereby the complexity will not increase linearly with increasing networking of the individual machine types.
  • the indicators or setting elements networked with one another and shown in FIG. 5 are shown.
  • the diagram shown here is defined by two group parameters, namely the group of cleaning-intensive adjustment variables and the group of waste-intensive adjustment variables, which variables are divided into vectors of different strengths.
  • Crossing points correspond to working points and the hatched area describes a field of all possible working points that can be set on the machine. Working points outside the field cannot be reached because there is at least one setting limit for the machine and this value simply cannot be set.
  • the procedure for selecting and using such a cleaning program could then proceed as follows.
  • the user of the machine or the system selects the table on the basis of the previously determined average value of the classifying stack (BW fibers, for example, from 7 ⁇ 8 "to 11 ⁇ 2" in 1 ⁇ 2 "steps, which corresponds to a fiber length of 22 mm to 38 mm)
  • BW fibers for example, from 7 ⁇ 8 "to 11 ⁇ 2" in 1 ⁇ 2 "steps, which corresponds to a fiber length of 22 mm to 38 mm
  • the degree of soiling of the cotton to be cleaned he selects a degree of cleaning intensity within the hatched program field that is considered correct for the fibers to be cleaned (mechanical stress on the fibers) and then selects the relative number for the finish based on the cross-linked tables, a working point is set within the hatched area that meets these conditions.
  • Figures 5 and 6 show the adjustable individual functions on a fine cleaning machine.
  • An opening roller with a number of peripherally arranged cleaning elements which can be viewed as cleaning stages over time, can be seen schematically. This is shown again in a clear linear representation in FIG. 6.
  • Each of the parameters P1 to P11 relates to an adjustable machine element within the cleaning stage (see also the CH patent application 3452 / 89-8).
  • a light arrow for the outlet and a dark arrow for the material passage are shown at each cleaning stage.
  • the parameters which act "intensely" on the fibers are e.g. in levels 2, 3, 4, 6 and the parameters with an "intensive" effect on the exit are e.g. in levels 3, 7. It can be seen that both parameter types can be present in the same cleaning level and that it is important to combine the settings of the same (desired) function type and not the cleaning levels.
  • the setting parameters are summarized in two groups and shown as tables.
  • the group of cleaning intensity includes a parameter P71, namely the drum speed in rpm from 600 to 1000.
  • the group of the discharge quantity also includes a parameter P72, namely the grate bar angle ⁇ ° from 0 to 20.
  • Networking with three function types also remains manageable if one of these three is designed in such a way that it only requires a choice and no setting.
  • An example would be a table stating provenances. This three-dimensional parameter map (provenance / intensity / departure) would be recorded on a provenance and the other two parameters, which define a two-dimensional field with the working points, would be set via an operating element. But it could be quickly and safely switched to another provenance and the associated tables for the other two controls or indicators would be assigned accordingly.
  • This example shows that the procedure for forming and applying group parameters can also be used consistently in simpler systems. This is not insignificant, because in groups of machine groups (and no longer just individual machines) machines of a simple type, that is machines with little to no parameter networking, and above all, can be included in the higher-level system.
  • the example of the coarse cleaning machine shows that even criteria as to how a machine works in relation to another machine can be taken into account, and that the table formation and the elimination of parameter vectors are also valid for a single parameter and thus each machine is included in the concept can.
  • the control of entire systems is done with optimization by a higher-level computer program, from which no system part then has to be specially treated.
  • bale opener An example of a bale opener
  • bale opener although assigned to the blow room in terms of process technology, is not a cleaning machine, but a disintegrating machine.
  • the card (not shown here) can be displayed with the help of a three-dimensional parameter field, i.e. with the same table technique as for the machines discussed above (also valid for machine groups) in a "room” with working points in which the cleaning intensity, the relative amount of waste and the Card intensity represents a property group with the associated parameter vectors.
  • the cleaning intensity is given, for example, by a clamping distance analogous to the clamping distance denoted by P4 in FIG. 6 and / or by the speed of the beater roller, while the delivery quantity is given, for example, by the position of the cleaning knives set on the beater roller and the carding intensity, for example by the distance between the carding elements and the drum set, as well as, where changeable, by changing the tooth density of the carding elements.
  • These setting options in the three groups are only to be understood as an example; Of course, much more of these can be summarized. In this way, for example, the nit level can be predefined and the cleaning intensity or the discharge can then be selected analogously to the procedure for a two-dimensional parameter field. Despite the possible variety of setting sizes, such settings are simple and manageable. Here, too, a complex process can be optimally operated using simple means.
  • the manufacturing process can be "tabulated" down to the card sliver, whereby further tables with parameter vectors can be derived from tables, for example a summarized optimized cleaning intensity and discharge for the entire system in addition to the tables for bale hardness and nit level.
  • This procedure is ideally suited for computer-controlled operation with table libraries (the indicators are set automatically). However, it is also suitable for manual operation (the indicators are set on controls), which would no longer be possible in a tabular form.
  • the tabulated form is understood to mean the machine or system setting based on parameter vectors derived from the tables.
