Definitions
- the invention relates to a method for controlling transport devices according to the preamble of claim 1. Such a method is known from DE-A-3 614 654.
- the invention has for its object to provide a control for the transport processes by means of which the most efficient way of working and thus the smallest possible number of transport devices is made possible.
- Rationalization can be achieved in this way, since the central computer receives information about at what point in time in the future what needs are to be expected.
- the remaining working time or deduction time until the next change process, which justifies the transport facility's need for action can be determined comparatively easily from the remaining length still to be delivered and the delivery speed.
- the working time still required i.e. the expected remaining time, which can be called up several times during the course of the entire working time.
- machine downtimes that have occurred in the course of working hours can be taken into account when controlling the transport equipment.
- the calculation of the remaining term is for spinning preparation machines, such as cards, draw frames or combing machines and also for flyers that have no speed adjustment, relatively easy.
- ring spinning machines are used for ring spinning machines with a large number of spindles, with a double stroke that executes double strokes during the assembly of cops and changes their height position with respect to the spindles from a starting position to an end position with a machine speed determining drive provided with a controller which, according to a spinning program, controls the machine speed during working hours for assembling the cops, as known from FR-A-2 461 034, means for forming a before the assembling of the cops available signal is provided, which is representative of the remaining working time until the finished cops are reached.
- ring spinning machines can also be included in the process, since signals can then also be called up several times during working hours, from which a future need for a bobbin change and / or a roving change can be determined.
- means are provided in the ring spinning machine for detecting the current position in the spinning program and for determining the remaining working time, taking into account the course of the spinning program.

- the signal required for the central computer can also be determined in a simple manner from the information already present on the spinning machine by the control of the machine containing a computer.
- means are provided for correcting the remaining working time resulting from the time span for the last double stroke of the ring bank and the number of double strokes still to be carried out, taking into account the changing machine speed according to the spinning program.

- the spinning program is usually designed in such a way that at the beginning of the bobbin build-up there is a lower machine speed than in the central region of the bobbin build-up. Towards the end of the bobbin build-up, the spindle speed (and thus the machine speed) is reduced again. This results in the diagram corresponding to FIGS.

- the information is first taken from the spinning program, how many lifting steps, in each of which a double stroke is carried out until the end of the cop assembly, the position "cops full" of the ring bench are required.
- the period of time required for the previous double stroke is measured. This measurement is carried out, for example, by incremental encoders arranged on the ring bench.
- Multiplying the number of lifting steps still required by the time span of the last double stroke results in the remaining working time or withdrawal time, which, however, is still subject to an error, since this does not take into account the changing machine speed, i.e. the changing after the spinning program Spindle speed and the correspondingly changing speed for the double stroke.
- the signal calculated by the computer on the basis of the preceding values is therefore corrected in the computer by means of a correction factor.
- This correction factor is formed by the computer from information that it takes from the spinning program. All future speed values of the spindles (machine speed) and the associated ring bench heights are known from the spinning program.
- the current spindle speed is multiplied by the ring bench height still to be covered for the remaining working time, ie the area created in FIG. 1 is calculated.
- the integral is formed from the actual course in accordance with the spinning program, ie the area created in FIG. 2. This integral (created area Fig. 2) is divided by the multiplication of the current spindle speed and the remaining ring bench height formed area (created area Fig. 1), which results in the correction factor.
- the signal explained above is newly formed at the end of each double stroke of the ring bank, the time required for this previous double stroke being used as a basis. This permanently newly generated signal is therefore available at any time, taking machine downtimes into account. It can also happen that the working speed of the spinning machine is reduced if an excessive number of thread breaks occurs must become. Such a reduction is also taken into account when forming the signal representative of the remaining working hours.

Description
Die Erfindung betrifft ein Verfahren zum Steuren von Transporteinrichtungen gemäß dem oberbegriff des Anspruchs 1. Ein derartiges Verfahren ist aus DE-A-3 614 654 bekannt.The invention relates to a method for controlling transport devices according to the preamble of
Es wird heute angestrebt, in Spinnereien die Transportvorgänge zu automatisieren und auch zu rationalisieren. Beispielsweise sind derartige Transportvorrichtungen durch die DE-A-3 614 654 beschrieben. Dort ist ein Transportsystem zum Transportieren der leeren und gefüllten Kannen offenbart, jedoch kann prinzipiell ein ähnliches Transportsystem auch zwischen anderen, zu einer Spinnerei gehörenden Maschinen vorgesehen werden, beispielsweise zwischen Spinnereivorbereitungsmaschinen untereinander, wie Karden, Strecken und Kämmereimaschinen oder für nachfolgende Maschinen, wie Flyer und Ringspinnmaschinen, sofern diese Ringspinnmaschinen eine Kannenvorlage aufweisen.Today, the aim is to automate and also rationalize the transport processes in spinning mills. For example, such transport devices are described by DE-A-3 614 654. There a transport system for transporting the empty and filled cans is disclosed, but in principle a similar transport system can also be provided between other machines belonging to a spinning mill, for example between spinning preparation machines among themselves, such as cards, draw frames and combing machines or for subsequent machines, such as flyers and ring spinning machines, provided that these ring spinning machines have a can template.
Der Erfindung liegt die Aufgabe zugrunde, eine Steuerung für die Transportvorgänge zu schaffen, durch die eine möglichst rationelle Arbeitsweise und damit eine möglichst geringe Zahl an Transportgeräten ermöglicht wird.The invention has for its object to provide a control for the transport processes by means of which the most efficient way of working and thus the smallest possible number of transport devices is made possible.
Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teil des Anspruchs 1 gelöst.This object is achieved by the features of the characterizing part of
Damit läßt sich eine Rationalisierung erreichen, da der zentrale Rechner Angaben darüber erhält, zu welchem in der Zukunft liegenden Zeitpunkt mit Bedarf welcher Art zu rechnen ist. Bei Maschinen, deren Arbeitszeit oder Abzugsende durch das Abliefern einer eingestellten Lieferlänge bestimmt wird, kann die Restarbeitszeit oder Restabzugszeit bis zu dem nächsten Wechselvorgang, welcher den Handlungsbedarf der Transporteinrichtung begründet, vergleichsweise einfach aus der restlichen, noch zu liefernden Länge und der Liefergeschwindigkeit ermittelt werden. Um dabei Unsicherheiten zu vermeiden, die durch unvorhersehbare Maschinenstillstände, beispielsweise Vorgarn- oder Luntenbrüche, verursacht werden, wird vorgesehen, daß die noch erforderliche Arbeitszeit, d.h. die voraussichtliche Restlaufzeit, während des Verlaufes der gesamten Arbeitszeit mehrfach abgerufen werden können. Dadurch lassen sich im Verlauf der Arbeitszeit eingetretene Maschinenstillstände bei der Steuerung der Transporteinrichtungen berücksichtigen.Rationalization can be achieved in this way, since the central computer receives information about at what point in time in the future what needs are to be expected. In the case of machines whose working time or end of deduction is determined by the delivery of a set delivery length, the remaining working time or deduction time until the next change process, which justifies the transport facility's need for action, can be determined comparatively easily from the remaining length still to be delivered and the delivery speed. In order to avoid uncertainties caused by unpredictable machine downtimes, e.g. roving or sliver breaks, it is provided that the working time still required, i.e. the expected remaining time, which can be called up several times during the course of the entire working time. As a result, machine downtimes that have occurred in the course of working hours can be taken into account when controlling the transport equipment.
Das Berechnen der Restlaufzeit ist für Spinnereivorbereitungsmaschinen, wie Karden, Strecken oder Kämmereimaschinen und auch für Flyer, die keine Drehzahlverstellung aufweisen, relativ einfach.The calculation of the remaining term is for spinning preparation machines, such as cards, draw frames or combing machines and also for flyers that have no speed adjustment, relatively easy.
An Ringspinnmaschinen (und auch an Flyern) mit einer Drehzahlverstellung ist die Ermittlung der Restlaufzeit dadurch erschwert, daß sich die Maschinengeschwindigkeit im Verlaufe des Abzuges verändert. Ferner richtet sich insbesondere bei Ringspinnmaschinen das Ende des Abzuges, d.h. das Ende der Arbeitszeit, nicht nach verarbeiteter Materiallänge, sondern nach der Fertigstellung des Spulenaufbaus.On ring spinning machines (and also on flyers) with a speed adjustment, the determination of the remaining runtime is made more difficult by the fact that the machine speed changes in the course of the take-off. Furthermore, especially in ring spinning machines, the end of the withdrawal, i.e. the end of the working time, not after the length of the processed material, but after the completion of the spool assembly.
Um auch Ringspinnmaschinen in das erfindungsgemäße Verfahren zum Steuern von Transporteinrichtungen einbeziehen zu können, werden für Ringspinnmaschinen mit einer Vielzahl von Spindeln, mit einer während des Aufbaus von Kopsen Doppelhübe ausführenden und bezüglich der Spindeln ausgehend von einer Anfangsposition bis zu einer Endposition ihre Höhenposition verändernden Ringbank und mit einem die Maschinengeschwindigkeit bestimmenden Antrieb, der mit einer Steuerung versehen ist, die nach einem Spinnprogramm die Maschinengeschwindigkeit während der Arbeitszeit zum Aufbauen der Kopse steuert, wie aus FR-A-2 461 034 bekannt, Mittel zum Bilden eines vor Abschluß des Aufbaus der Kopse abrufbaren Signals vorgesehen, das für die bis zum Erreichen der fertigen Kopse verbleibende Restarbeitszeit repräsentativ ist. Durch diese Ausbildung können auch Ringspinnmaschinen in das Verfahren einbezogen werden, da an ihnen dann ebenfalls mehrfach während der Arbeitszeit Signale abgerufen werden können, aus denen ein in der Zukunft liegender Bedarf für einen Kopswechsel und/oder für einen Vorgarnwechsel ermittelt werden kann.In order to also be able to include ring spinning machines in the method according to the invention for controlling transport devices, ring spinning machines are used for ring spinning machines with a large number of spindles, with a double stroke that executes double strokes during the assembly of cops and changes their height position with respect to the spindles from a starting position to an end position with a machine speed determining drive provided with a controller which, according to a spinning program, controls the machine speed during working hours for assembling the cops, as known from FR-A-2 461 034, means for forming a before the assembling of the cops available signal is provided, which is representative of the remaining working time until the finished cops are reached. With this design, ring spinning machines can also be included in the process, since signals can then also be called up several times during working hours, from which a future need for a bobbin change and / or a roving change can be determined.
In weiterer Ausgestaltung der Erfindung wird vorgesehen, daß bei der Ringspinnmaschine Mittel zum Erfassen der augenblicklichen Position im Spinnprogramm und zum Ermitteln der noch unter Berücksichtigung des Verlaufs des Spinnprogramms verbleibenden Restarbeitszeit vorgesehen sind. Diese Angaben können in das Spinnprogramm eingearbeitet werden, so daß bei Abfragen der augenblicklichen Position gleichzeitig eine Information über die Restarbeitszeit abgegeben werden kann.In a further embodiment of the invention, it is provided that means are provided in the ring spinning machine for detecting the current position in the spinning program and for determining the remaining working time, taking into account the course of the spinning program. This information can be found in the spinning program can be incorporated so that information about the remaining working time can be given when querying the current position.
Bei einer anderen Ausführungsform einer Ringspinnmaschine sind Mittel zum Erfassen der für den jeweils letzten Doppelhub der Ringbank benötigten Zeitspanne, Mittel zum Ermitteln der noch bis zum Erreichen der vollen Kopse durchzuführenden Anzahl von Doppelhüben und Mittel zum Errechnen der sich aus diesen beiden Werten ergebenden Restarbeitszeit vorgesehen. Dabei wird ausgenutzt, daß hier keine zusätzlichen Informationen in der Spinnmaschine abgelegt und abgespeichert werden müssen. Das für den zentralen Rechner benötigte Signal kann in einfacher Weise aus den an der Spinnmaschine ohnehin vorhandenen Informationen von der einen Rechner enthaltenden Steuerung der Maschine ebenfalls ermittelt werden kann. In zweckmäßiger Ausgestaltung sind dabei Mittel zum Korrigieren der sich aus der Zeitspanne des für den letzten Doppelhub der Ringbank und der noch auszuführenden Anzahl von Doppelhüben ergebenden Restarbeitszeit unter Berücksichtigung der sich gemäß dem Spinnprogramm ändernden Maschinengeschwindigkeit vorgesehen. Damit wird sichergestellt, daß bei der Restarbeitszeitberechnung keine Fehler gemacht werden.In another embodiment of a ring spinning machine, means are provided for recording the time period required for the last double stroke of the ring bench, means for determining the number of double strokes to be carried out until the full heads are reached, and means for calculating the remaining working time resulting from these two values. This takes advantage of the fact that no additional information has to be stored and stored in the spinning machine. The signal required for the central computer can also be determined in a simple manner from the information already present on the spinning machine by the control of the machine containing a computer. In an expedient embodiment, means are provided for correcting the remaining working time resulting from the time span for the last double stroke of the ring bank and the number of double strokes still to be carried out, taking into account the changing machine speed according to the spinning program. This ensures that no errors are made when calculating the remaining working time.
Im nachstehenden wird die Restarbeitszeitberechnung einer Ringspinnmaschine an einem Beispiel erläutert. Die nicht dargestellte Ringspinnmaschine besitzt eine Vielzahl von Ringspindeln, die auf beiden Maschinenseiten angeordnet sind. Diese Ringspindeln werden von einem Antrieb angetrieben, der mittels einer einen Rechner enthaltenden Steuerung gesteuert ist. Dabei kann ein gemeinsamer Antrieb für alle Spindeln oder ein abschnittsweise Antrieb oder auch ein Antrieb mit Einzelmotoren vorgesehen werden. Jeder Ringspindel ist ein Streckwerk zugeordnet, wobei die Streckwerke einer Maschinenseite oder beider Maschinenseiten einen gemeinsamen Antrieb aufweisen, der ebenfalls von der Steuerung gesteuert wird. Auf beiden Maschinenseiten befinden sich weitere Ringbänke, die zur Erzielung eines vorgegebenen Kopsaufbau in bestimmter Weise Hub- und Senkbewegungen durchführen. Dabei wird die Höhe der Ringbank in Relation zu den Spindeln schrittweise erhöht, so daß sich der bekannte Kopsaufbau ergibt.In the following, the remaining working time calculation of a ring spinning machine is explained using an example. The ring spinning machine, not shown, has a large number of ring spindles which are arranged on both machine sides. These ring spindles are driven by a drive which is controlled by means of a control system containing a computer. A common drive for all spindles or a section-by-section drive or also a drive with individual motors can be provided. A drafting system is assigned to each ring spindle, the drafting systems on one machine side or on both machine sides having a common drive, which is also controlled by the control. There are further ring banks on both sides of the machine, which are used to achieve one perform the specified bobbin construction in a certain manner. The height of the ring bench in relation to the spindles is gradually increased, so that the known cop construction results.
Die Ringspinnmaschine arbeitet nach einem sogenannten Spinnprogramm, das in seinem Schema in Fig. 1 und 2 dargestellt ist. Nach diesem Spinnprogramm werden die Spindeldrehzahlen (n) und damit auch die Geschwindigkeiten der übrigen Elemente, insbesondere der Streckwerke und der Hub- und Senkbewegung der Ringbank in gleichem Maße verändert. Das Spinnprogramm ist üblicherweise so ausgelegt, daß zu Beginn des Kopsaufbaus eine geringere Maschinengeschwindigkeit als in dem mittleren Bereich des Spulenaufbaus vorliegt. Gegen Ende des Spulenaufbaus wird die Spindeldrehzahl (und damit auch die Maschinengeschwindigkeit) wieder abgesenkt. Damit ergibt sich das Diagramm entsprechend Fig. 1 und 2, bei welcher die Spindeldrehzahl über der Ringbankposition aufgetragen ist, d.h. der Ringbankhöhe (h), um die diese Ringbank von der absenkten Anfangsposition schrittweise bis zu der Endposition angehoben wird, bei welcher der Kopsaufbau abgeschlossen ist, d.h. die Stellung "Kops voll" erreicht worden ist. Dieses Vorschalten der Ringbankhöhe (h), der die Hub- und Senkbewegung überlagert ist, d.h. der sogenannte Doppelhub, kann beispielsweise durch eine Klinkenschaltung oder auch durch einen Schrittmotor durchgeführt werden. In der Praxis wird eine Unterteilung in einzelne Abschnitte vorgenommen, in welchen die Spindeldrehzahl (Maschinengeschwindigkeit) konstant gehalten und anschließend stufenweise erhöht oder auch abgesenkt wird. Dies bedeutet, daß die Spindeldrehzahl (n) über eine gewisse Hubhöhe konstant gehalten wird, d.h. die Spindeldrehzahl (ni) über die Differenz der Ringbankhöhe (Δhi), worauf sich dann die Drehzahlen (ni+1) für die Differenz der Ringbankhöhe (Δhi+1) usw. anschließen. Um zu einem beliebigen Zeitpunkt die verbleibende Restarbeitszeit festzustellen, wird zunächst aus dem Spinnprogramm die Information entnommen, wieviel Hubschritte, in denen jeweils ein Doppelhub durchgeführt wird, noch bis zu dem Ende des Kopsaufbaus, der Stellung "Kops voll" der Ringbank benötigt werden. Zusätzlich wird die Zeitspanne gemessen, die für den vorausgegangenen Doppelhub benötigt wird. Diese Messung erfolgt beispielsweise durch an der Ringbank angeordnete Inkrementalgeber. Aus der Multiplikation der Anzahl der noch benötigten Hubschritte mit der Zeitspanne des letzten Doppelhubs ergibt sich die noch verbleibende Restarbeitszeit oder Abzugszeit, die allerdings noch mit einem Fehler behaftet ist, da hierbei nicht die sich ändernde Maschinengeschwindigkeit berücksichtigt ist, d.h. die sich nach dem Spinnprogramm ändernde Spindeldrehzahl und die sich ebenfalls entsprechend ändernde Geschwindigkeit für den Doppelhub. Das von dem Rechner aufgrund der vorhergehenden Werte errechnete Signal wird deshalb in dem Rechner mittels eines Korrekturfaktors korrigiert. Dieser Korrekturfaktor wird von dem Rechner aus Informationen gebildet, die er dem Spinnprogramm entnimmt. Aus dem Spinnprogramm sind alle zukünftigen Drehzahlwerte der Spindeln (Maschinengeschwindigkeit) und die zugehörigen Ringbankhöhen bekannt. Es wird hierzu die momentane Spindeldrehzahl mit der noch für die Restarbeitszeit verbleibenden zurückzulegenden Ringbankhöhe multipliziert, d.h. die in Fig. 1 angelegte Fläche berechnet. Des weiteren wird das Integral aus dem tatsächlichen Verlauf entsprechend dem Spinnprogramm gebildet, d.h. die in Fig. 2 angelegte Fläche. Dieses Integral (angelegte Fläche Fig. 2) wird durch die Multiplikation der momentanen Spindeldrehzahl und der verbleibenden Ringbankhöhe gebildete Fläche (angelegte Fläche Fig. 1) dividiert, wodurch sich der Korrekturfaktor ergibt.The ring spinning machine works according to a so-called spinning program, which is shown in its diagram in FIGS. 1 and 2. According to this spinning program, the spindle speeds (n) and thus also the speeds of the other elements, in particular the drafting units and the lifting and lowering movement of the ring rail, are changed to the same extent. The spinning program is usually designed in such a way that at the beginning of the bobbin build-up there is a lower machine speed than in the central region of the bobbin build-up. Towards the end of the bobbin build-up, the spindle speed (and thus the machine speed) is reduced again. This results in the diagram corresponding to FIGS. 1 and 2, in which the spindle speed is plotted over the ring bench position, ie the ring bench height (h) by which this ring bench is gradually raised from the lowered starting position to the end position at which the cop assembly is completed is, ie the position "Kops full" has been reached. This upstream of the ring bench height (h), which is superimposed on the lifting and lowering movement, ie the so-called double stroke, can be carried out, for example, by means of a pawl circuit or also by means of a stepper motor. In practice, a subdivision is made into individual sections, in which the spindle speed (machine speed) is kept constant and then gradually increased or decreased. This means that the spindle speed (n) is kept constant over a certain lifting height, ie the spindle speed (ni) over the difference in the ring bench height (Δhi), whereupon the speeds (ni + 1) for the difference in the ring bench height (Δhi + 1) etc. connect. In order to determine the remaining working time at any time, the information is first taken from the spinning program, how many lifting steps, in each of which a double stroke is carried out until the end of the cop assembly, the position "cops full" of the ring bench are required. In addition, the period of time required for the previous double stroke is measured. This measurement is carried out, for example, by incremental encoders arranged on the ring bench. Multiplying the number of lifting steps still required by the time span of the last double stroke results in the remaining working time or withdrawal time, which, however, is still subject to an error, since this does not take into account the changing machine speed, i.e. the changing after the spinning program Spindle speed and the correspondingly changing speed for the double stroke. The signal calculated by the computer on the basis of the preceding values is therefore corrected in the computer by means of a correction factor. This correction factor is formed by the computer from information that it takes from the spinning program. All future speed values of the spindles (machine speed) and the associated ring bench heights are known from the spinning program. For this purpose, the current spindle speed is multiplied by the ring bench height still to be covered for the remaining working time, ie the area created in FIG. 1 is calculated. Furthermore, the integral is formed from the actual course in accordance with the spinning program, ie the area created in FIG. 2. This integral (created area Fig. 2) is divided by the multiplication of the current spindle speed and the remaining ring bench height formed area (created area Fig. 1), which results in the correction factor.
Das vorstehend erläuterte Signal wird am Ende jedes Doppelhubes der Ringbank neu gebildet, wobei die für diesen vorausgegangenen Doppelhub benötigte Zeit zugrundegelegt wird. Dieses permanent neu gebildete Signal steht deshalb jederzeit abrufbar zur Verfügung, wobei dann Maschinenstillstände berücksichtigt werden. Ebenso kann es vorkommen, daß bei Auftreten einer zu hohen Fadenbruchzahl die Arbeitsgeschwindigkeit der Spinnmaschine reduziert werden muß. Auch eine derartige Reduzierung wird bei der Bildung des jeweils für die Restarbeitszeit repräsentativen Signals berücksichtigt.The signal explained above is newly formed at the end of each double stroke of the ring bank, the time required for this previous double stroke being used as a basis. This permanently newly generated signal is therefore available at any time, taking machine downtimes into account. It can also happen that the working speed of the spinning machine is reduced if an excessive number of thread breaks occurs must become. Such a reduction is also taken into account when forming the signal representative of the remaining working hours.
