the compilation of a preliminary list includes the identification of acceptable yarn take-off components, taking into account information on desired properties of the yarn and information on the raw material.
Fig. 1 a method for determining optimal spinning components for a rotor spinning process according to the prior art is shown.
a yarn manufacturer 101 provides information 102 regarding the raw material of the fibers, the yarn and the desired yarn destination to technical experts 104 of a rotor spinning part manufacturer.
fiber information 102 may include information related to fineness, length, or blend of the raw fiber material.
the desired yarn includes the type of yarn that yarn manufacturer 101 wishes to produce.
the technical experts 104 summarize their technical knowledge in a technical expertise 105, which can include carrying out various experimental tests with different yarn spinning processes in which the components of the spinning rotor were varied in each test. These experimental tests can be confirmed by the technical experts 104 by means of supplementary so-called confirmation tests.
the technical experts 104 opt for a selection 106 of optimal spinning components.
This information is provided for the yarn manufacturer 101 for a practical method 107 in the rotor spinning process in which the proposed optimal spinning components are installed or set as recommended.
the yarn manufacturer 101 then carries out a production run 108 using the suggested optimal spinning components.
Fig. 2 is a schematic general overview of the interrelationship of the rotor spinning knowledge system according to the present invention and a yarn manufacturer 1.
the yarn manufacturer 1 provides information 2 relating to the Obtain raw material from which the desired yarn is made as well as information regarding the desired yarn properties 3.
the yarn manufacturer 1 consults the rotor spinning knowledge system in a consultation 4.
the consultation 4 includes entering known yarn information 2 and the desired yarn target 3 in accordance with certain prescribed dimensions, which will be discussed later, into a conventional digital computer loaded with, for example, a software version of the rotor spinning knowledge system of the present invention.
Consultation 4 involves a number of questions that must be answered by yarn manufacturer 1 in order to obtain information for the process by the rotor spinning knowledge system of the present invention.
the data entered are processed by the computer under the control of the rotor spinning knowledge system and recommendations for the proposed optimal spinning components for use in the rotor spinning process are ultimately displayed to the yarn manufacturer 1.
the yarn manufacturer 1 realizes the proposals offered by the rotor spinning knowledge system by means of an embodiment 6 which includes the installation or adjustment of identified optimal spinning components and the production 7 of the desired yarn.
the series of information from collected questions and answers are collectively referred back to the consultation and are graphically depicted in the flow chart of Fig. 3, which additionally schematically shows the process steps performed by the digital computer in accordance with the instructions of the rotor spinning knowledge system.
a printout of a representative consultation includes important information entered by the user, questions asked by the user of the rotor spinning knowledge system, a listing of various rules, and the display of values that have been set in accordance with rules and include values that are given by the rules that correspond to user information have been determined and rules that are only used in circumstances where no user information was available.
FIG. 3 is a flow chart of the control sequence of the rotor spinning knowledge system.
the rotor spinning knowledge system of the present invention is designed to operate in the manner of conventional so-called expert systems, and accordingly includes the use of background and foreground chain rules and control blocks and other conventional characteristics of such expert systems.
the rotor spinning knowledge system was realized in practical application through the use of conventional expert system software in the form of IBM software and expert system environment software.
the user is asked for information regarding the type and production capacity of the spinning machine in which the recommended spinning components are to be used by the rotor spinning knowledge system. This query activity is shown as block 10 in FIG. 3. In response to this query from block 10, the user identifies the type of spinning machine.
the user can summarize the information required during the consultation on a form with entries by hand, as is represented representatively in FIG. 4. Then the user would refer to an heading "A machine data" and specifically to the name of the spinning box type and manually enter the previously mentioned entries into the computer on the specified form.
the knowledge base of the rotor spinning knowledge system provides a substitute value in connection with a specified type of a spinning machine if no information has been specified by the yarn manufacturer 1. For example, in the representative consultation, the rotor spinning knowledge system controls the computer to provide a substitute value for a "SE8" type spinning machine in response to the absence of a user response to prompt block 10.
a block 12 in FIG. 3 represents that Input of the information of the spinning machine type by the user.
the next step in the control sequence is a prompt, represented by block 14, for data regarding the number of spinning units.
This prompt is referred to as "ANZ SPINNST" in the tax sequence.
the knowledge system may include a rule that the number of spinning units must be divisible by a predetermined number, for example 24. If such a rule is applied, the knowledge system makes a distinction, represented by block 16 in FIG. 3, although the number of spinning positions entered by the user fulfills this rule. If the number of spinning positions entered by the user cannot be divided by the predetermined number, the knowledge system forms a replacement number of spinning positions. The replacement number of spinning positions can be checked at a later step in the control sequence to decide whether the number is suitable.
the next step in the control sequence is a prompt, represented by block 18, for information regarding the final product application of the yarn.
the rules in the knowledge system related to the end product of the yarn are referred to in the expression as "MISSION M” and "MAKE W".
Each of the two rules includes a so-called ejection rule, which is used to exclude the application of the other rule if one of the two rules fulfills the information entered by the user.
the user in response to the prompt shown in block 18, the user must specify whether the end product of the yarn is either a woven or a knitted fabric, with satisfactory application of either of the two rules.
the premise of the rule "INTENDED USE W" is fulfilled and the ejection rule is applied to the knowledge system of the parameters of the other application in question (in this example Knitted fabrics) during the rest of the consultation.
the knowledge base of the knowledge system includes factual knowledge regarding those yarn characteristics that are preferably considered depending on the end product.
the user is prompted with a prompt requesting information regarding safe yarn characteristics associated with a yarn for use in a fabric, and this prompt is represented by block 26.
Figure 4 is a listing of selected yarn characteristics which the user can wish in a yarn that will ultimately be used in a fabric.
the knowledge system allows the user to choose a sequence based on the importance of special yarn properties in the yarn. For example, the user can indicate that a desired yarn property is a high degree of hairiness.
the rotor spinning knowledge system includes rules that relate the yarn properties to the end product, which it Yarn includes the quality characteristics of the yarn and the type of raw material from which the yarn will be made.
An example of such a rule is shown below in the printout of the representative consultation:
the rotor spinning knowledge system determines a selected relative level of each of the desired characteristics. For example, if denim is the type of fabric to be produced and the yarn needs to be processed into a chain in an intermediate process, the rotor spinning knowledge system can apply a rule as follows:
the rotor spinning knowledge system prompts the user to obtain information regarding the raw material from which the yarn is to be produced, shown as block 30 in Fig. 3.
the user can provide an answer, shown as block 32 that the raw material of the yarn is, for example, synthetic material, a mixture of synthetic and natural fibers or cotton.
the printout indicates that cotton was selected as the raw material in the representative consultation:
the monitor rule "MIX OF INPUT (1)" described above prevents the knowledge system from including parameters of the fiber mixture if the selected raw material is not a fiber mixture (i.e. a mixture of synthetic and natural fibers).
the knowledge system contains various "DONT CONSIDER" blocking rules regarding each unselected raw material.
the unselected raw material includes raw materials that consist of a mixture of synthetic and wool fibers and a mixture of synthetic and cotton fibers.
the knowledge system additionally contains control blocks, which contain rules, which ensure that the cumulative percentage of the respective raw material is 100.
the rotor spinning knowledge system can be configured to promptly output to the user for the desired or preferably used yarn number range, represented by block 34 in Fig. 3. If such information is desired, the user sees this information as shown by the Block 36 before.
the rotor spinning knowledge system then presents questions to the user regarding the properties of the selected raw material.
a predetermined chain of rules is applied. For example, if the selected raw material is a synthetic material, the rotor spinning knowledge system applies a predetermined set of rules, represented by block 38. Alternatively, if the raw material is a fiber blend, the rotor spinning knowledge system applies a different chain of rules, represented by block 40. As an additional Alternatives may branch the rotor spinning knowledge system into yet another predetermined chain of rules about obtaining information that the raw material is cotton, as represented by block 42 in FIG. 3.
the knowledge system can promptly provide the user with information about the properties of the synthetic fibers, for example the preferred length and fineness of fibers used.
the knowledge system promptly issues to the user, represented by block 46, for information on the proportion of natural fibers, the proportion of synthetic fibers, the amount of fibers preferably used, and the fiber fineness.
the knowledge system can promptly prompt the user for information on the minimum yarn number.
the knowledge system requests a value of "GFH MIN INPUT” and then displays a minimum yarn count based on the user response of "14".
the knowledge system receives information that the raw material is 100% cotton or, as represented by block 48, that the natural fiber content of a selected blend of fibers is cotton, the knowledge system promptly issues a message to the user to inform him of shell residues or inform waste in the cotton raw material.
the knowledge system prompts the user to confirm that the peel or waste content of the cotton material is known. If the shell or waste content of the cotton raw material is not known, the knowledge system allocates a predetermined proportion of dirt, as shown by block 52, and displays this predetermined proportion of dirt to the user. Alternatively, if the user replies to the prompt, represented by block 50, that the peel or dirt content of the cotton material is known, the knowledge system promptly issues the user with information regarding a preferred or desired level of the peel or dirt content of the cotton material. In this case, the user can enter information into any conventional unit, for example the Shirley Trash Seperator. If desired, the knowledge system can be configured to indicate the tolerances of individual rotor types and sizes with respect to a maximum shell and dirt content of the cotton material, which can still be accepted for the specific type or size of the rotors.
the rotor spinning knowledge system sets values for the dirt content and shell content of the raw material from which the yarn is to be produced. As shown below, the knowledge system sets the peel and dirt content to a value "0" if the raw material is a synthetic material or a fiber blend that contains no cotton.
the knowledge system sets the shell and dirt content to 0 if the user does not explain a specified value. For this reason, the knowledge system displays a corresponding warning that the proposed raw material is not suitable and that the suitable rotor cannot be identified if the raw material is cotton or a fiber mixture that contains cotton and the amount of shell and dirt is 100 on a scale of 100 to 0.
the following excerpt from the printout shows this control sequence.
the knowledge system contains an exception to the control sequence described above, which generates a warning to the user regarding the lack of a usable rotor. If the end product is diapers or flannel, then the knowledge system shows no warning to the user. This is shown in the extract shown above as “AND (ART W IS NOT 'BED LINEN, NAPPED) (FLANELLE” or not, then ART W) ".
the knowledge system sets the content of the shell and dirt portion to 0, which refers to a raw material that is mainly free of any foreign matter; consequently, all rotors can be used for such a shell and dirt-free raw material. Properties other than the shell and dirt content of the raw material will therefore influence the decision made by the knowledge system regarding the coating of the rotor and opening roller.
the knowledge system decides the value for the twist to be introduced into the yarn as an "alpha” value and represented by block 56 in Fig. 3. More specifically, the knowledge system decides an "alpha” value based on the end product of the yarn tenacity and other required properties. Below is an excerpt from the printout showing a possible rule that the knowledge system can use to decide on an "alpha” value.
the decision of the yarn twist or the "alpha" value is shown below.
the knowledge system promptly issues a message to the user for information regarding the desired fiber fineness, as represented by block 58 in Fig. 3.
the user is specifically asked to provide information regarding the maximum rotor speed.
the knowledge system uses a large number of rules, by means of which the maximum rotor speed is fixed at an intended value, which is dependent on secured yarn properties, such as the fiber fineness below a predetermined value or fiber length below a predetermined value. If one or more of these specified fiber properties meets the rule, the maximum rotor speed is set to a predetermined value, for example 100 rpm.
a predetermined value for example 100 rpm.
the knowledge system calculates the warpage value in connection with the desired yarn tenacity and the designated maximum rotor speed as shown by block 60 in FIG. 3. If the calculated warpage quantity is a value outside the range of standard values, for example a value from 30 to 212 the knowledge system applies a rule to decide whether the calculated delay value is within a predetermined range, as represented by block 62 in FIG. 3. If the calculated delay value lies outside a predetermined range, the knowledge system promptly issues a message to the user to decide whether another warping area can be used, including, for example, a rotor that has a larger exhaust nozzle, as shown by block 64 in FIG. 3.
the knowledge system can be designed to provide the user with individual Provide opportunities for the display if the proposed alternative B ezugwert is acceptable, as shown by block 66.
the knowledge system will then automatically select a higher delay size in the event that the user does not select an alternative delay size. For example, the knowledge system can automatically evaluate a delay range between 39 and 276.
the knowledge system calculates the minimum and maximum number of fibers in cross-section, as represented by block 68 in FIG. 3.
the minimum number of fibers in cross-section is expressed as a value per 100 fibers in cross-section.
the knowledge system compares the calculated minimum number of fibers in cross-section and the maximum number of fibers with current values to decide whether these values can be achieved by the method, as shown by block 70 in Fig. 3. If the calculated number of fibers in cross-section does not reach there is Knowledge system an indication on the display, as shown by block 72 in Fig. 3.
the user receives a prompt to select or set a useful number of fibers in cross section. Such a display is shown below as an extract from the printout.
the knowledge system then promptly issues a message to the user for information regarding the desired quality standard of the yarn, as represented by block 74 in FIG. 3.
the knowledge system provides three quality levels.
a quality level is called “service life”, and the yarns produced with this quality level have a high level of stability and are of relatively average quality.
the next higher quality level is referred to as "quality” and refers to a relatively high quality level which is achieved when the speed of the rotor is relatively high.
the highest quality level is referred to as "extra quality” and relates to the highest quality of the yarn that can be achieved (this quality level may only be attainable by a rotor speed below the maximum necessary rotor speed).
the choice of one of these three quality levels by the user affects the type of spinning components that can be suggested as a result of the consultation.
the selection of the "service life” quality level really results in the last recommendation of spinning components, such as the rotor and opening roller, which are provided with special coatings.
the selection of the quality level "extra quality” gives a recommendation that the recommended rotor should only work at a speed which is below its maximum speed.
the rotor spinning knowledge system then describes a first list of acceptable yarn take-off nozzles, as represented by block 76 in Figure 3.
the first list is acceptable yarn take-off nozzles described, based on information which is preferably provided by the user or was otherwise determined during the consultation regarding the raw material, the properties of the raw material and the selected quality level of the yarn.
Below is an extract from the representative consultation, which shows the application of a rule for the decision of a possible yarn take-off nozzle:
the rotor spinning knowledge system collects a preliminary list of acceptable spinning rotors. For this reason, the knowledge system includes information regarding the percentage of contamination of the cotton material, the amount of fibers and properties of the yarn to be produced, taking into account a recommended preliminary list of acceptable spinning rotors. Furthermore, the rotor spinning knowledge system can be designed to determine suitable coating properties of the selected acceptable spinning rotors. For example, if "aggressive" cotton is used as the raw material, use a borated rotor that is included in the list of acceptable spinning rotors. Below is an extract from the printout, which shows a rule for the selection of a suitable rotor coating:
the rotor spinning knowledge system denotes a rotor Calculation, including information that includes the acceptable dirt content of the cotton raw material, the yarn tenacity, the yarn properties in terms of uniformity and tendency to curl, as represented by block 82 in FIG. 3.
the rotor spinning knowledge system includes the speed of the identified rotor in relation to the selected raw material in its calculations.
the knowledge system takes into account the specified quality parameters, such as the standard, both quality or extra quality as well as the thread number range. As shown in the extract from the representative consultation below, the application of such a rule is included for further refinement of the list of identified acceptable rotors.
the rotor spinning knowledge system applies further rules to decide whether an acceptable rotor is available for a relatively wide range of yarn numbers and a lower one Quality level.
the rotor spinning knowledge system thus decides whether a rotor can be identified that is able to work in the given yarn number range and can produce a yarn with a lower quality level than the initially identified quality level. In the event that no acceptable rotors can be identified, the rotor spinning knowledge system shows this to the user on a display.
the rotor spinning knowledge system Based on the refined list of identified acceptable rotors, the rotor spinning knowledge system further identifies those rotors that are optimal for the desired yarn and finished product manufacture, as represented by block 86 in FIG. 3. For this reason, the rotor spinning knowledge system relies on productivity and the special properties of the desired yarn in the identification of the optimal rotor. In addition to identifying the optimal rotor, the rotor spinning knowledge system identifies useful components for the identified optimal rotors, such as suitable yarn take-off nozzles.
the rotor spinning knowledge system specifies the optimal rotor spinning device components and their optimal working conditions, as represented by block 88 in Fig. 3.
the rotor spinning knowledge system can be designed to specify the rotor type, i.e. the rotor diameter and the preferred use of a rotor coating.
the last step of the consultation concerns the display of the identified optimal components and their optimal working parameters, as represented by the block 90 in Fig. 3.
the rotor spinning knowledge system can provide information regarding preferably applicable opening rollers, rotor coating, rotor chamber, Show preventive cleaning, level cleaner, torque stop and maximum possible speed of the optimal rotor.
