Abstract
Description
In der Literatur werden Vorrichtungen gezeigt, die zur automatischen Inspektion von Geweben und Gewirken an einer Produktionslinie geeignet sind. Im weiteren soll hier die Webmaschine als Beispiel dienen. Dies gilt jedoch ebenso für Gewirk, Strick und Legemaschinen. In the literature devices are shown which are used for the automatic inspection of fabrics and knitted fabrics a production line. The weaving machine will serve as an example here. this applies but also for knitted fabrics, knitting and laying machines.
Diese werden auch in einigen Patentanmeldungen CH_PS 508 755, US_PS 3 502 115, EP 84 114 337.5 und DE 35 29 058 A1, die verwendeten Sensorelemente sind in EP 0596 715 B1 genannt, konnten sich bisher jedoch nicht durchsetzen. Ein Grund hierfür dürften vermutlich in den bis heute ungelösten Problemen Verschmutzung, hoher Arbeitsabstand und damit hoher virtueller Raumbedarf und ungleichmäßige Erfassung des Webguts durch das Sensorsystem mit vorgeschalteter Optik liegen. These are also described in some patent applications CH_PS 508 755, US_PS 3 502 115, EP 84 114 337.5 and DE 35 29 058 A1, the sensor elements used are mentioned in EP 0596 715 B1, have so far been able to but not enforce. One reason for this is probably the problems that have not yet been solved Contamination, high working distance and thus high virtual space requirements and uneven detection of the woven material through the sensor system with optics upstream.
Die bisher in der Literatur gezeigten Verfahren basieren auf Flächenkameras und Zeilenkameras Sie sind alle mit Abstand zur Webmaschine angeordnet, da sie auf eine Abbildungsoptik zwischen sich und dem Flächengebilde angewiesen sind. Damit muß ein Freiraum zwischen der Webmaschine und dem Sensor entstehen, der im Betrieb nicht von Menschen betreten werden darf. The methods previously shown in the literature are based on area scan cameras and line scan cameras They are all arranged at a distance from the weaving machine because they have an imaging optics between themselves and the Fabrics are instructed. So there must be a space between the weaving machine and the sensor arise that must not be entered by people in the company.
Sie sind zwar, je nach Aufhängung, von den Schwingungen der Webmaschine entkoppelt, erkennen dafür aber Bewegungen der Maschine, die das Flächengebilde mit bewegen, als Fehler im Gebilde. Depending on the suspension, they are decoupled from the vibrations of the weaving machine, but they do recognize them Movements of the machine that move the fabric as errors in the structure.
Hinzu kommt die Verschmutzungsproblematik des Abbildungssystems durch Staub und Flug in den Produktionsräumen. In addition, there is the pollution problem of the imaging system due to dust and flight in the Production rooms.
Diese Aufgaben werden erfindungsgemäß dadurch gelößt, daß ein Sensor verwendet wird, welcher aufgrund seiner kleinen Bauform einen direkten Kontakt zum Gewebe herstellen kann. According to the invention, these objects are achieved in that a sensor is used which is based on its small design can make direct contact with the tissue.
Damit kann die Verschmutzungsproblematik durch die Verwendung des Flächegewebes als "Putztuch" gelöst werden. So the problem of pollution can be solved by using the flat fabric as a "cleaning cloth" become.
Durch den Verzicht auf eine gemeinsame Abbildungsoptik und damit die Ausbildung des Sensors in der Länge identisch zum Webgut ermöglicht dieses System eine an jeder Stelle des Flächengebildes gleiches Licht- und Sensorverhalten und damit eine identische Erfassung der Oberfläche über die ganze Breite. By dispensing with a common imaging optics and thus the length of the sensor identical to the weave, this system enables the same light and light at every point of the fabric Sensor behavior and thus an identical detection of the surface across the entire width.
Durch die spezielle Ausgestaltung der Sensoranordnung wird eine Trennung zwischen Erschütterungen und Störungen im Flächengebilde möglich. Due to the special design of the sensor arrangement, a separation between vibrations and Faults in the fabric possible.
Durch die gewählten Aufhängungen werden die Schwingungen an der Vorrichtung, die durch die Fertigungsmaschine induziert werden, nochmals deutlich vermindert. The vibrations on the device caused by the Manufacturing machine induced, significantly reduced again.
Aufgrund der besonderen Art der Abtastung kann ein Mustervergleich in der Anlage durchgeführt werden. Due to the special type of scanning, a pattern comparison can be carried out in the system.
Im folgenden wird die Erfindung anhand von Ausführungsbeispielen und der Zeichnungen näher erläutert, es zeigen: The invention is explained in more detail below with the aid of exemplary embodiments and the drawings demonstrate:
Fig. 1 eine schematische Anordnung der Sensorelemente in 2 Reihen Fig. 1 shows a schematic arrangement of the sensor elements in 2 rows

Claims (12)
Dies geschieht beispielsweise bei der Anordnung nach Anspruch 2 durch die Überprüfung der zeitlichen oder örtlichen Korrelation von Abweichungen im Flächengebildebild des Sensors. Stellt sich eine zeitliche Korrelation über mehrere Sensoren ein, so handelt es sich um eine Störung von außen. Ist die Korrelation über mehrere Sensoren so gegeben, daß die Korrelation dem mechanischen Abstand des Sensors entspricht, so handelt es sich um eine Störung im Flächengebilde.
Bei der Anordnung nach Anspruch 3 ist die Unterscheidung ebenfalls über eine zeitliche oder entlang des Kippwinkels des Sensor liegende Korrelation möglich. 6. Apparatus according to claim 1 to 5, characterized in that in the evaluation due to the arrangement of the sensor elements to each other and the material feed by an evaluation unit by comparing the spatial and temporal correlation of disturbances in the image signal can be decided whether a distortion in the fabric as an origin Has a defect in the fabric or a disturbance from the outside.
This is done, for example, in the arrangement according to claim 2 by checking the temporal or local correlation of deviations in the fabric image of the sensor. If there is a time correlation across several sensors, this is a disturbance from the outside. If the correlation across several sensors is such that the correlation corresponds to the mechanical distance of the sensor, then there is a disturbance in the fabric.
In the arrangement according to claim 3, the differentiation is also possible via a correlation over time or along the tilt angle of the sensor.
Hier wird das Prinzip der Schaukel für den Sensor umgesetzt, welches eine Übertragung von Querkräften zwischen den Aufhängeösen und der Schaukelfläche verhindert, andererseits aber die Übertragung von Querkräften, die nicht zur Schwingungsachse des Stoffs gehören, erlaubt. Damit verringern sich die übertragbaren Schwingungen zwischen Maschine und Vorrichtung. 8. The device according to claim 1 to 7, characterized in that the sensor itself is in a mechanically rigid housing which is softly suspended by fasteners in such a way that vibrations only lead to a rotary movement about the suspension point on the machine.
The principle of the swing for the sensor is implemented here, which prevents the transfer of transverse forces between the suspension eyes and the swing surface, but on the other hand allows the transfer of transverse forces that do not belong to the vibration axis of the fabric. This reduces the vibrations that can be transmitted between the machine and the device.
