Definitions
- the present invention is based on systems for inspecting material strips, in particular special metal strips, for example steel strips.
- the inspection systems usually have a control panel and screens on which the information determined by the surface inspection system is displayed.
- the inspection by the quality engineer also requires a constant turning away from the tape to the monitors, which leads to distractions and reduced attention.
- the invention has for its technical object to provide a system for inspecting material strips and a method for operating the system for inspecting material strips, which do not have the disadvantages of the prior art, but by a targeted, precise approach to the detected Missing time in the inspection save by the quality engineer and support the quality engineer in his assessment so that his full attention is devoted to the surface of the material band.
- a system comprising a material strip, a surface inspection system, a marking unit, a reading device, a database and a visualization device, the marking unit being configured to position markers, for example barcodes etc., for marking a position on the material strip to apply the material strip, the surface inspection system being configured to detect defects in the material strip and their position, the database being configured to store and reproduce data relating to defects and their position detected by the surface inspection system, the reading device being read out the position marker is configured, the visualization device being configured to assign position markers read by the reading device to data on defects from the database, the visualization device being configured to identify defects to mark an optical overlay, especially within the assigned position or position.
- the marking unit being configured to position markers, for example barcodes etc., for marking a position on the material strip to apply the material strip
- the surface inspection system being configured to detect defects in the material strip and their position
- the database being configured to store and reproduce data relating to defects and their position detected by the surface inspection system
- the reading device being read out the position marker is configured
- the system according to the invention makes it possible, by using the position markers, to assign information about defects to the correct positions on the material strip stored in the database. A time-consuming search for the fault over many meters is no longer necessary. Furthermore, the marking of the imperfections by means of optical superimposition is a great relief for the quality engineer, since his eyes no longer have to constantly switch between the surface of the material strip and a screen.
- An optical superimposition in the sense of the present invention is an overlay in an image of the material band, either by an optical projection directly onto the material band, the material band serving as a projection surface for projecting the marking, by imaging the marking on an intermediate level between the strip of material and the eye of the viewer of the optical overlay, preferably the quality engineer, or by generating a virtual image.
- the material band is a metal band, preferably a steel band.
- the marking unit can be, for example, a printer, a laser and / or a quality tracking unit. If a printer is used in particular, it can be used for printing directly on the material tape. It is also conceivable that the printer cker is configured to print on labels and stick them on the material tape as position markers. Finally, it is conceivable that the printer prints the position markers with a dye on the material band or applies the position markers with a laser to the material band by means of laser serablation.
- the quality tracking unit is configured, for example, to apply a position (location reference) on the material strip in the form of a barcode.
- the database is computer-implemented. It is also conceivable that the reading device comprises a camera for reading out the position markers. It is also conceivable that the visualization device is either stationary or is designed as a mobile device. If the visualization device is designed as a mobile device, it is conceivable that the visualization device can be configured as a function of the user.
- the visualization device is configured to display additional data on the defects from the database by optical superimposition. This enables the attention of the quality engineer to be increased and less distraction due to the additional local bundling of the information available. It is conceivable, for example, that the additional data have measurement data and / or measurement data collected by the surface inspection system from at least one further database or from at least one other (third-party) system. However, it is also conceivable that the additional data have information regarding the position of the fault.
- the reading device is integrated in the visualization device. This enables an advantageous direct link between the visualization device and the reading device. Local inaccuracies in the marking of the defects, which could arise due to relative displacements of the visualization device and the reading device, are largely avoided in this way. But it is also conceivable that the reading device is locally separated from the visualization device and is arranged, for example, directly above the material band. This enables a precise setting of the reading device for reading out the position markers.
- the visualization device has augmented reality glasses. Augmented Reality is a computer-assisted extension of the perception of reality.
- the design of the visualization device with augmented reality glasses enables largely fatigue-free work for the quality engineer. Markings of imperfections can be faded in by the augmented reality glasses directly at the appropriate position in the field of vision of the quality engineer. It is conceivable that the visualization device is configured in such a way that the optical overlay is personalized. It would be conceivable, for example, that the language in which text represented by optical overlay is output is adjustable.
- the visualization device has a projection unit, in particular a video projector and / or a laser marking. This enables the marking of defects by optical superimposition by a projection directly onto the material strip, where, for example, augmented reality glasses can advantageously be dispensed with by wearing.
- the system has a winding device which is configured to move the material strip past the visualization device along its main direction of extension. This advantageously makes it possible to approach a recognized fault. It is conceivable that the winding device is configured to move areas of the material strip past the visualization device at high speed without defects and to move and / or stop the defects at the speed at low speed.
- the position markers have machine-readable code, the position markers preferably being quality tracking barcodes or other barcodes or 2D markings. This enables easy, clear and secure marking of positions on the material tape.
- the marking unit is configured to regularly position the position markers Spacing on the material tape.
- Distances in the sense of the preferred embodiment of the present invention are distances in the direction of the main direction of extent of the material strip. It is conceivable that the distances are in the range from 10 cm to 200 cm, preferably in the range from 50 cm to 100 cm.
- the system has a recognition device for recognizing gestures, the recognition device being configured to control the visualization device on the basis of the gestures it knows and / or wherein the recognition device is configured to Control the winding device based on the recognized gestures.
- a recognition device for recognizing gestures the recognition device being configured to control the visualization device on the basis of the gestures it knows and / or wherein the recognition device is configured to Control the winding device based on the recognized gestures.
- Another object of the present invention to solve the task at the outset is a method for operating a system according to the invention.
- the method according to the invention makes it possible, by using the position markers, to assign information stored in the database on defects to the correct positions on the material strip and to enable the quality engineer to significantly facilitate his work by the optical overlay.
- the marking unit can be, for example, a printer, a laser and / or a quality tracking unit. If a printer is used in particular, the printer can print directly on the material tape. It is also conceivable that the printer prints labels and sticks them on the material tape as position markers. It is also conceivable that the printer prints the position markers with a dye on the material strip or applies the position markers with a laser to the material strip by means of laser ablation. Finally, it is conceivable that the quality tracking unit is configured to apply a position (location reference) on the material strip in the form of a barcode.
- position markers for marking a position on the material strip are applied to the material strip by the marking unit, where defects of the material strip and their position are recognized by the surface inspection system, data from the database relating to defects recognized by the surface inspection system and their position are stored, the position markers being read out by the reading device, position marks read out by the visualization device from the reading device being assigned data on defects from the database and the defects being marked accordingly, the defects being marked by the visualization device by optical superimposition .
- the visualization device uses optical superimposition to display additional data on the defects from the database. In an advantageous manner, this further facilitates the work of the quality engineer through the further concentration of information
- the material strip is moved past the visualization device along its main direction of extension by the winding device. This advantageously makes it possible to approach a recognized fault. It is conceivable that areas of the material strip are moved past the visualization device at high speed without defects and the defects are moved past and / or stopped at the speed at the visualization device.
- the visualization device is controlled using gestures recognized by the recognition device and / or wherein the winding device is controlled using gestures recognized by the recognition device.
- gestures recognized by the recognition device and / or wherein the winding device is controlled using gestures recognized by the recognition device.
- the control of the visualization device and / or the winding device by means of gestures is very intuitive.
