Definitions
- the invention relates to a method and a device for monitoring the production quality of glass containers which, coming from a glass machine, pass through a cooling furnace and are provided with a mechanically readable code which relates to the respective shape of the glass machine.
- An exact quality control is only possible after leaving the cooling furnace, which is increasingly carried out today by automatic inspection devices. For example, they check the containers for cracks, wall thickness and mouth size deviations as well as inclusions in the material and internal injuries. Defective containers are automatically sorted out mechanically.
- the known control devices have the disadvantage that defective containers are discarded without regard to their origin and thus the form causing the error, and because of their return as a raw material in the manufacturing process are removed from a later origin control. Due to the long throughput time through the cooling furnace and the subsequent control rhythm of random samples, form-number-related errors are only recognized one or two hours after occurrence by manually reading the imprint of the form number that was engraved into the mold, although such errors are usually caused by defective molds Manufacture of the containers have arisen.
- Continuous recording and automatic evaluation of the containers identified as defective and ejected in terms of their origin and thus the form causing the errors should thus be carried out, at the earliest possible point in time, so that constant quality control is carried out with respect to the individual forms of a glass machine. in order to minimize production losses in this way.
- the method for monitoring the production quality of glass containers is characterized according to the invention in that after the separation, the containers are transported to a code reader arranged at the outlet of the cooling furnace, which is connected to a process computer for storing the identity of each container in the order supplied to the code reader, that subsequently or previously with the aid of a temporarily intervening in the flow of containers, the process computer or mechanically controllable stop device consisting of a selectable number of containers and that after a pause due to group formation has elapsed, the containers are fed in groups to one or more inspection machines by means of which containers with errors can be sorted out, the information of which is evaluated in the sequence of the identified containers of a group in the process computer in order to determine an error trend will.
- the device provided for the application of this method for monitoring the manufacturing quality of glass containers is designed according to the invention in such a way that a code reader is assigned to a conveyor belt conveying the containers from the cooling furnace, which code reader is connected to a process computer for storing the identity of each container in the order supplied to the code reader is connected in front of or after the code reader, a stop device intervening temporarily in the flow of the containers for forming container groups consisting of a selectable number of containers, which can be controlled by the process computer or mechanically, and that the code reader has one or more inspection machines , by means of which containers with errors can be sorted out, are connected downstream, which are connected to the process computer in order to transmit their information in the order of the identified containers of a group.
- One or more numerical displays can also be connected to the process computer, so that monitoring is possible at any time not only in the area of the inspection line, but also directly on the glass machine.
- the method according to the invention for monitoring the production quality of glass containers or the device for using this method are effective in that the continuously supplied containers are combined into individual groups, for example upstream of the code reader, by means of the process computer and the stopping device. After a pause, which can correspond to approximately ten container diameters, the entry into the inspection line is released. The containers can now pass through the code reader and are identified by it. The code reader signals the identity of each container in the process computer, which stores the container numbers in sequence in the memory. After a certain number of containers has expired, the entry into the code reader is stopped and a pause is made again. The number of containers in the group is also saved.
- the process computer receives the signals "container being checked” and “container bad” from the individual inspection machines. The longer absence of these signals indicates to the process computer that a pause has passed. This is the sign for the process computer to use the form number sequence stored in the memory for the following group of containers.
- the process computer advances one number in the form number sequence. If the "container bad" signal now occurs, the current number of the form number sequence is regarded as belonging to the container and this number is processed further. Since this container is ejected, it must also be removed in the form number sequence in the memory; the stored number of containers in this group is corrected by minus one, so that this group can be used with the next inspection machine located on the inspection line.
- the process computer determines an error trend from these tables, so that an automatic evaluation of the containers identified as defective and separated out can take place at the earliest possible time with regard to their origin and the form causing the error.
- the personnel who operate the production system are thus constantly informed about the respective quality level and can take targeted measures to improve quality more quickly than before by replacing a defective mold. A significant increase in production can therefore be achieved through the quality-related statement, since sources of error relating to an incorrect form can be recognized immediately and in this way major production downtimes are avoided.
- a glass machine 1 is used to produce containers 2, which are fed via a conveyor belt 3 in the direction of an arrow 4 to a cooling furnace 6. If necessary, a counter 5 is arranged in the vicinity of the entrance to the cooling furnace 6, so that information about the number of containers fed to the cooling furnace is obtained.
- the relaxed containers are conveyed via a conveyor belt 8 in the direction of a palletizing station 9.
- the containers 2 first pass a code reader 1o and then inspection devices 11 and 12, which check the various properties of the containers 2 have, e.g. B. whether there are cracks, wall thickness or mouth size deviations or inclusions in the glass. Defective containers are sorted out by the inspection devices 11 and 12.
- a stop device 13 In front of the code reader 1o is a stop device 13 which can temporarily interrupt the transport of the containers 2 on the continuously running conveyor belt 8.
- the code reader 1 0 , the device 13, the inspection devices 11 and 12 and possibly further inspection devices and the counter 5 are connected via lines 14 to a process computer 15, the memory contents of which can be monitored via line 17 on a display 16 by the operating personnel of the production plant.
- the process computer 15 controls the stop device 13 such that it is brought into the transport path of the containers 2, whereby 8 groups 2 'of containers are formed when the conveyor belt continues to run. After a pause has elapsed, which corresponds to approximately ten container diameters in one exemplary embodiment, the transport of the container groups 2 ′ on the conveyor belt 8 is released again by the stop device 13. The containers now run past the code reader 1o, which reports the identity of each container to the process computer 15. This stores the numbers in sequence in a memory. After passing through a certain quantity of containers, a pause is generated again by activating the stop device 13. In addition, the number of containers is also stored, based on each of the container groups 2 '.
- the process computer 15 receives information from the inspection devices 11, 12 that a container check is taking place and also additional information if defective containers are discarded. Receives the process computer 15 no signals from one of the inspection devices 11, 12, then it is a matter of running through a pause described above, with the aid of which the process computer establishes the relationship between the form number sequence read and the container sequence checked.
- the process computer 15 advances by one number in the form number sequence associated with the respective inspection device. If it receives a signal for the rejection of a container, the current number of the form number sequence is regarded as belonging to the defective container and processed further. Since the container in question is discarded, the information relating to it in the associated form number sequence of the memory must also be removed. The number of containers stored in this group is reduced by one and this sequence is used with the signals from the subsequent inspection machine.

Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren sowie eine Vorrichtung zur Überwachung der Fertigungsqualität von Glasbehältern, die,von einer Glasmaschine kommend einen Kühlofen durchlaufen und mit einem auf die jeweilige Form der Glasmaschine bezogenen, mechanisch lesbaren Code versehen sind.The invention relates to a method and a device for monitoring the production quality of glass containers which, coming from a glass machine, pass through a cooling furnace and are provided with a mechanically readable code which relates to the respective shape of the glass machine.
Eine Glasmaschine mit bis zu zehn unabhängigen Stationen mit jeweils 1 bis 4 Formen produziert Behälter, die unmittelbar nach der Verfestigung zur Entspannung des Materials etwa eine Stunde einen Kühlofen durchlaufen. Erst nach dem Verlassen des Kühlofens ist eine exakte Qualitätskontrolle möglich, die heute in zunehmendem Maß durch automatische Inspektionsgeräte durchgeführt wird. Diese prüfen die Behälter beispielsweise auf Risse, Wandstärken- und Mündungsmaßabweichung sowie Einschlüsse im Material und Innenverletzungen. Defekte Behälter werden hierbei auf mechanische Weise selbsttätig ausgesondert.A glass machine with up to ten independent stations, each with 1 to 4 molds, produces containers that pass through a cooling furnace for about an hour immediately after solidification to relax the material. An exact quality control is only possible after leaving the cooling furnace, which is increasingly carried out today by automatic inspection devices. For example, they check the containers for cracks, wall thickness and mouth size deviations as well as inclusions in the material and internal injuries. Defective containers are automatically sorted out mechanically.
Die bekannten Kontrollvorrichtungen haben den Nachteil, daß defekte Behälter ohne Beachtung ihrer Herkunft und somit der fehlerverursachenden Form ausgesondert werden und wegen ihrer Rückführung als Rohstoff in den Herstellungsprozeß einer späteren Herkunftskontrolle entzogen sind. Aufgrund der langen Durchlaufzeit durch den Kühlofen sowie den anschließenden Kontrollrhytmus von Stichproben werden formnummernbezogene Fehler durch manuelles Lesen des Abdrucks der durch Gravur in die Form eingebrachten Formnummer erst ein bis zwei Stunden nach Auftreten erkannt, obwohl solche Fehler in der Regel durch defekte Formen schon bei der Herstellung der Behälter entstanden sind.The known control devices have the disadvantage that defective containers are discarded without regard to their origin and thus the form causing the error, and because of their return as a raw material in the manufacturing process are removed from a later origin control. Due to the long throughput time through the cooling furnace and the subsequent control rhythm of random samples, form-number-related errors are only recognized one or two hours after occurrence by manually reading the imprint of the form number that was engraved into the mold, although such errors are usually caused by defective molds Manufacture of the containers have arisen.
Eine Kontrolle, bezogen auf die einzelnen Formen der Glasmaschine findet hierbei jedoch nicht statt, die defekte Form muß vielmehr gesondert ermittelt werden. Dieses Verfahren ist zeitaufwendig, so daß erhebliche Produktionsausfälle in Kauf genommen werden müssen.A check, based on the individual shapes of the glass machine, does not take place here, the defective shape must rather be determined separately. This process is time-consuming, so that considerable production losses have to be accepted.
Es ist daher Aufgabe der Erfindung, ein Verfahren zur Überwachung der Fertigungsqualität von Glasbehältern sowie eine Vorrichtung zur Anwendung dieses Verfahrens zu schaffen, wodurch eine eindeutige Identifizierung eventuell vorhandener, fehlerhafter Formen und damit eine rasche Fehlerbeseitigung möglich ist. Es soll somit eine kontinuierliche Aufzeichnung und automatische Auswertung der als defekt erkannten und ausgeworfenen Behälter hinsichtlich ihrer Herkunft und somit der Fehler verursachenden Form bewerkstelligt werden, und zwar zu dem frühest möglichen Zeitpunkt, so daß eine ständige Qualitätskontrolle bezogen auf die einzelnen Formen einer Glasmaschine erfolgt, um auf diese Weise Produktionsausfälle auf ein Mindestmaß zu verringern.It is therefore an object of the invention to provide a method for monitoring the production quality of glass containers and an apparatus for using this method, whereby a clear identification of any defective forms that may be present and thus a rapid error correction is possible. Continuous recording and automatic evaluation of the containers identified as defective and ejected in terms of their origin and thus the form causing the errors should thus be carried out, at the earliest possible point in time, so that constant quality control is carried out with respect to the individual forms of a glass machine. in order to minimize production losses in this way.
Das Verfahren zur Überwachung der Fertigungsqualität von Glasbehältern, ist gemäß der Erfindung dadurch gekennzeichnet, daß die Behälter nach der Vereinzelung zu einem am Auslauf des Kühlofens angeordneten Codeleser transportiert werden, der mit einem Prozeßrechner zur Speicherung der Identität jeden Behälters in der dem Codeleser zugeführten Reihenfolge in Verbindung steht, daß anschließend oder zuvor mit Hilfe einer zeitweise in den Fluß der Behälter eingreifenden, von dem Prozeßrechner oder mechanisch steuerbaren Stoppvorrichtung aus einer wählbaren Anzahl von Behältern bestehende Behältergruppen gebildet werden, und daß nach Ablauf einer durch die Gruppenbildung bedingten Pause die Behälter gruppenweise einer oder mehreren Inspektionsmaschinen mittels denen mit Fehlern behaftete Behälter aussortierbar sind, zugeführt werden, deren Informationen in der Reihenfolge der identifizierten Behälter einer Gruppe in dem Prozeßrechner zur Ermittlung eines Fehlertrends ausgewertet werden.The method for monitoring the production quality of glass containers is characterized according to the invention in that after the separation, the containers are transported to a code reader arranged at the outlet of the cooling furnace, which is connected to a process computer for storing the identity of each container in the order supplied to the code reader, that subsequently or previously with the aid of a temporarily intervening in the flow of containers, the process computer or mechanically controllable stop device consisting of a selectable number of containers and that after a pause due to group formation has elapsed, the containers are fed in groups to one or more inspection machines by means of which containers with errors can be sorted out, the information of which is evaluated in the sequence of the identified containers of a group in the process computer in order to determine an error trend will.
Zweckmäßig ist es hierbei, die zwischen den Behältergruppen einzulegenden Pausen in Abhängigkeit von dem Durchmesser der Behälter festzulegen.It is expedient here to determine the pauses to be inserted between the groups of containers as a function of the diameter of the containers.
Die zur Anwendung dieses Verfahrens vorgesehene Vorrichtung zur Überwachung der Fertigungsqualität von Glasbehältern ist gemäß der Erfindung derart ausgebildet, daß einem die Behälter aus dem Kühlofen fördernden Transportband ein Codeleser zugeordnet ist, der mit einem Prozeßrechner zur Speicherung der Identität jeden Behälters in der dem Codeleser zugeführten Reihenfolge in Verbindung steht, daß vor oder nach dem Codeleser eine zeitweise in den Fluß der Behälter eingreifende Stoppvorrichtung zur Bildung von aus einer wählbaren Anzahl von Behältern bestehenden Behältergruppen angeordnet ist, die von dem Prozeßrechner oder mechanisch steuerbar ist, und daß dem Codeleser eine oder mehrere Inspektionsmaschinen, mittels denen mit Fehlern behaftete Behälter aussortierbar sind, nachgeschaltet sind, die zur Übermittlung ihrerInformationen in der Reihenfolge der identifizierten Behälter einer Gruppe an den Prozeßrechner angeschlossen sind.The device provided for the application of this method for monitoring the manufacturing quality of glass containers is designed according to the invention in such a way that a code reader is assigned to a conveyor belt conveying the containers from the cooling furnace, which code reader is connected to a process computer for storing the identity of each container in the order supplied to the code reader is connected in front of or after the code reader, a stop device intervening temporarily in the flow of the containers for forming container groups consisting of a selectable number of containers, which can be controlled by the process computer or mechanically, and that the code reader has one or more inspection machines , by means of which containers with errors can be sorted out, are connected downstream, which are connected to the process computer in order to transmit their information in the order of the identified containers of a group.
Vorteilhaft ist es hierbei, als Transportband ein ständig umlaufendes Gliederkettenband vorzusehen und als Codeleser eine vertikal unter den Behälter angeordnete Diodenkamera zu verwenden, in die der am Boden der Behälter angeordnete Code durch einen von oben kommenden Lichtblitz projezierbar ist und die zur Auswertung einen an den Prozeßrechner angeschlossenen Microprozessor aufweist.It is advantageous here to provide a continuously rotating link chain belt as a conveyor belt and to use a diode camera arranged vertically below the container as a code reader, into which the code arranged on the bottom of the container can be projected by a flash of light coming from above and which is sent to the process computer for evaluation connected microprocessor.
An den Prozeßrechner können des weiteren ein oder mehrere numerische Displaysangeschlossen werden, so daß eine Überwachung nicht nur im Bereich der Inspektionslinie, sondern auch unmittelbar an der Glasmaschine jederzeit möglich ist.One or more numerical displays can also be connected to the process computer, so that monitoring is possible at any time not only in the area of the inspection line, but also directly on the glass machine.
Das erfindungsgemäße Verfahren zur Überwachung der Fertigungsqualität von Glasbehältern bzw. die Vorrichtung zur Anwendung dieses Verfahrens sind in der Weise wirksam, daß mittels des Prozeßrechners und der Stoppvorrichtung die kontinuierlich zugeführten Behälter beispielsweise vor dem Codeleser zu einzelnen Gruppen zusammengefaßt werden. Nach Ablauf einer Pause, die etwa zehn Behälterdurchmessern entsprechen kann, wird der Einlauf in die Inspektionslinie freigegeben. Die Behälter können nun den Codeleser passieren und werden durch diesen identifiziert. Der Codeleser signalisiert die Identität jedes Behälters in den Prozeßrechner, der die Nummern der Behälter der Reihenfolge nach im Speicher niederlegt. Nach Ablauf einer bestimmten Behälteranzahl wird der Einlauf in den Codeleser gestoppt und erneut eine Pause eingelegt. Die Anzahl der Behälter in der Gruppe wird ebenfalls gespeichert.The method according to the invention for monitoring the production quality of glass containers or the device for using this method are effective in that the continuously supplied containers are combined into individual groups, for example upstream of the code reader, by means of the process computer and the stopping device. After a pause, which can correspond to approximately ten container diameters, the entry into the inspection line is released. The containers can now pass through the code reader and are identified by it. The code reader signals the identity of each container in the process computer, which stores the container numbers in sequence in the memory. After a certain number of containers has expired, the entry into the code reader is stopped and a pause is made again. The number of containers in the group is also saved.
Der Prozeßrechner erhält von den einzelnen Inspektionsmaschinen die Signale "Behälter wird geprüft" und "Behälter schlecht". Das längere Ausbleiben dieser Signale zeigt dem Prozeßrechner den Durchlauf einer Pause an. Dies ist für den Prozeßrechner das Zeichen, für die nun folgende Gruppe von Behältern die im Speicher abgelegte Formnummernfolge zu verwenden.The process computer receives the signals "container being checked" and "container bad" from the individual inspection machines. The longer absence of these signals indicates to the process computer that a pause has passed. This is the sign for the process computer to use the form number sequence stored in the memory for the following group of containers.
Mit jedem Signal "Behälter wird geprüft" rückt der Prozeßrechner in der Formnummernfolge eine Nummer weiter. Erfolgt nun das Signal "Behälter schlecht", wird die aktuelle Nummer der Formnummernfolge als dem Behälter zugehörig betrachtet und diese Nummer weiterverarbeitet. Da dieser Behälter ausgeworfen wird, muß er in der Formnummernfolge im Speicher ebenfalls entfernt werden, die gespeicherte Anzahl der Behälter dieser Gruppe wird um minus eins korrigiert, so daß diese Gruppe mit der nächsten an der Inspektionslinie befindlichen Inspektionsmaschine verwendet werden kann.With each signal "container is being checked", the process computer advances one number in the form number sequence. If the "container bad" signal now occurs, the current number of the form number sequence is regarded as belonging to the container and this number is processed further. Since this container is ejected, it must also be removed in the form number sequence in the memory; the stored number of containers in this group is corrected by minus one, so that this group can be used with the next inspection machine located on the inspection line.
Bei Störungen im Ablauf der Behälter werden durch Stauerscheinungen auf den Gliederbändern die Pausen zusammengeschoben und vernichtet. Dies detektiert der Prozeßrechner durch eine nun falsche Anzahl von Behältern in Gruppen zwischen zwei Pausen. Eine eventuell bereits erfolgte Nummernzuordnung zu defekten Behältern in dieser Gruppe wird zurückgezogen, da sie nicht sicher ist. Diese Behälter werden nun als unidentifiziert ausgewiesen. Mit der nächsten "Behälterpause" jedoch wird nun der Synchronismus wieder hergestellt.In the event of faults in the flow of the containers, the breaks are pushed together and destroyed due to congestion on the link belts. The process computer detects this by an incorrect number of containers in groups between two breaks. Any number assignment to defective containers in this group that has already been made is withdrawn because it is not secure. These containers are now identified as unidentified. With the next "container break", however, the synchronism is restored.
An jeder Inspektionslinie werden somit die vom Codeleser gelieferten Folgen von Formnummern den entsprechenden.Signalen der Inspektionsmaschinen zugeordnet werden. Als-Ergebnis dieser Zuordnung entsteht eine Tabelle, in der aufgelaufene Fehler-Stück auf Inspektionsmaschine und Formnummer bezogen sind. Um die Arbeit des Codelesers zu überwachen, werden in einer weiteren Tabelle gelesene Stück pro Formnummer aufsummiert. Mit dem numerischen Display und der Funktionstastatur können diese Tabellen Zeile für Zeile zu Kontrollzwecken dargestellt werden.At each inspection line, the sequences of form numbers supplied by the code reader will be assigned to the corresponding signals of the inspection machines. As a result of this assignment, a table is created in which accumulated defects are related to the inspection machine and form number. To monitor the work of the code reader, pieces read per form number are added up in another table. With the numerical display and the Functional keyboard, these tables can be displayed line by line for control purposes.
Der Prozeßrechner ermittelt aus diesen Tabellen einen Fehlertrend, so daß eine automatische Auswertung der als defekt erkannten und ausgesonderten Behälter hinsichtlich ihrer Herkunft und der fehlerverursachenden-Form zum frühest möglichen Zeitpunkt erfolgen kann. Das Personal, das die Fertigungsanlage bedient, ist somit ständig über den jeweiliegen Qualitätsstand informiert und kann gegebenenfalls rascher als bisher gezielte Maßnahmen zur Qualitätsverbesserung treffen, indem eine schadhafte Form gezielt ausgewechselt wird. Durch die qualitätsbezogene Aussage ist demnach eine erhebliche Produktionssteigerung zu erzielen, da Fehlerquellen bezogen auf eine fehlerhafte Form sofort erkennbar sind und auf diese Weise größere Produktionsausfälle vermieden werden.The process computer determines an error trend from these tables, so that an automatic evaluation of the containers identified as defective and separated out can take place at the earliest possible time with regard to their origin and the form causing the error. The personnel who operate the production system are thus constantly informed about the respective quality level and can take targeted measures to improve quality more quickly than before by replacing a defective mold. A significant increase in production can therefore be achieved through the quality-related statement, since sources of error relating to an incorrect form can be recognized immediately and in this way major production downtimes are avoided.
In der Zeichnung ist ein Ausführungsbeispiel der gemäß der Erfindung ausgebildeten Vorrichtung zur Überwachung der Fertigungsqualität von Glasbehältern schematisch dargestellt und nachfolgend im einzelnen erläutert.In the drawing, an embodiment of the device designed according to the invention for monitoring the manufacturing quality of glass containers is shown schematically and explained in detail below.
Mittels einer Glasmaschine 1 werden Behälter 2 gefertigt, die über ein Förderband 3 in Richtung eines Pfeils 4 einem Kühlofen 6 zugeführt werden. Gegebenenfalls ist in der Nähe des Eingangs des Kühlofens 6 ein Zähler 5 angeordnet, so daß man eine Information über die Anzahl der dem Kühlofen zugeführten Behälter erhält.A glass machine 1 is used to produce
In Richtung von Pfeilen 7 werden die entspannten Behälter über ein Transportband 8 in Richtung auf einen Palettierungsplatz 9 gefördert. Dabei passieren die Behälter 2 zunächst einen Codeleser 1o und danach Inspektionsgeräte 11 und 12, die verschiedene Eigenschaften der Behälter 2 nachzuprüfen haben, z. B. ob Risse, Wandstärken- oder Mündungsmaßabweichungen bzw. Einschlüsse im Glas vorliegen. Defekte Behälter werden hierbei von den Inspektionsgeräten 11 und 12 ausgesondert.In the direction of
Vor dem Codeleser 1o ist eine Stoppvorrichtung 13, die den Transport der Behälter 2 auf dem kontinuierlich laufenden Transportband 8 zeitweise unterbrechen kann. Der Codeleser 10, die Vorrichtung 13, die Inspektionsgeräte 11 und 12 sowie gegebenenfalls weitere Inspektionsgeräte und der Zähler 5 sind über Leitungen 14 an einen Prozeßrechner 15 angeschlossen, dessen Speicherinhalte über eine Leitung 17 an einem Display 16 vom Bedienungspersonal der Fertigungsanlage überwacht werden können.In front of the code reader 1o is a
Der Prozeßrechner 15 steuert die Stoppvorrichtung 13 derart, daß diese in den Transportweg der Behälter 2 gebracht wird, wodurch bei weiterlaufendem Transportband 8 Gruppen 2' von Behältern gebildet werden. Nach Verstreichen einer Pause, die bei einem Ausführungsbeispiel etwa zehn Behälterdurchmessern entspricht, wird der Transport der Behältergruppen 2' auf dem Transportband 8 durch die Stoppvorrichtung 13 wieder freigegeben. Die Behälter laufen nunmehr an dem Codeleser 1o vorbei, der die Identität eines jeden Behälters dem Prozeßrechner 15 meldet. Dieser legt die Nummern der Reihenfolge nach in einem Speicher ab. Nach Durchlauf einer bestimmten Menge von Behältern wird erneut eine Pause durch Aktivierung der Stoppvorrichtung 13 erzeugt. Darüber hinaus erfolgt auch eine Speicherung der Behälterzahl, bezogen auf jede der Behältergruppen 2'.The
Gleichzeitig erhält der Prozeßrechner 15 von den Inspektionsgeräten 11, 12 Informationen, daß eine Behälterprüfung stattfindet und daneben weitere Informationen, sofern mangelhafte Behälter ausgesondert werden. Erhält der Prozeßrechner 15 keine Signale von einem der Inspektionsgeräte 11, 12, dann handelt es sich um den Durchlauf einer oben beschriebenen Pause, mit deren Hilfe der Prozeßrechner die Beziehung zwischen gelesener Formnummernfolge und geprüfter Behälterreihenfolge herstellt.At the same time, the
Mit jedem Signal, das von einem der Inspektionsgeräte 11, 12 kommt und "Behälterprüfung" bedeutet, rückt der Prozeßrechner 15 in der dem jeweiligen Inspektionsgerät zugehörigen Formnummernfolge um eine Nummer weiter. Erhält er ein Signal für das Aussondern eines Behälters, wird die aktuelle Nummer der Formnummernfolge als dem defekten Behälter zugehörig betrachtet und weiterverarbeitet. Da der betreffende Behälter ausgesondert wird, muß die ihn betreffende Information in der zugehörigen Formnummernfolge des Speichers ebenfalls entfernt werden. Die gespeicherte Behälterzahl dieser Gruppe wird um eine reduziert und diese Folge mit den Signalen der nachfolgenden Inspektionsmaschine verwendet.With each signal that comes from one of the
Auf diese Weise ist eine ständige qualitätsbezogene Aussage und eine formbezogene Kontrolle möglich.In this way, a constant quality-related statement and a form-related control is possible.
