- All quality-relevant parameters of the casting process can be used for continuous casting the individual strand section are assigned properly in the cutting station. Thus the assignment of these parameters also after the cutting station for each individual Strand section is maintained, the strand sections with a marker be provided by the human eye and / or by a machine optical detection can be read.
- strand sections are after the cutting station with a marker such as beat numbers, barcode, point code, etc. provided. Instead of a marker The strand sections can also by attaching, welding or nailing a Sheet metal labels with the appropriate data can be made visible.
- Non-machine identifiable strand sections must, if possible to be identified by the human eye or remain unidentifiable lie as a committee.
- the invention is based on the object, a method and a device for easy and error-free automated recognition of identification data of semi-finished products, in particular of strand sections after the separation cut in a continuous casting plant and using this identification data to sort the strand sections for subsequent manufacturing processes.
- the method and the device for Recognition of the identification data should increase the identification security in the further require little space in the plant layout, be inexpensive and automatable as well make the use of expensive marking unnecessary or such facilities greatly simplify.
- the inventive method and apparatus are useful for the identification of Strand sections optically recognizable surface features at the interface of Strand sections, through the separating cut, regardless of the separation method, on applied the release surface and / or attached by a marking device were.
- basically all optically recognizable features are usable, such as geometry of the strand section, surface roughness, texture, structural properties, separation-specific surface features and / or markings etc.
- the Device for identifying the strand sections is particularly simplified by that the images in the cutting or identification station with a first camera and the images at the sorting point with a second camera with substantially the same Facilities are generated. Such cameras are relatively small and are against heat radiation easy to protect.
- the identification as such takes place with the digital ones Image data that is processed in the database according to the comparison method in the computer room be similar to the OCV (Optical Character Verifying) method. An assignment the sense content of a geometrically recognized mark can in the inventive Procedure omitted.
- the separation method such as flame cutting, scissors, laser, plasma, cutting disc, be different visually recognizable features on the separation surface, as the identification surface serves, upset.
- the optically recognizable features on the predetermined Identification surface created by a cutting shear or by a flame cut become.
- identification features in addition to simple Markings are provided. These simple marks can be e.g. the location of the billet facing the camera, or a gross sorting through the human eye, for example on a storage site. According to one Another embodiment may be advantageous if, prior to the first image acquisition Markings applied as additional optical features on the identification surface become easily recognizable by the camera, such as numerical or alphanumeric characters, special characters, color samples, graphic symbols Etc.
- a mark for example, the date of casting open or encrypted include.
- Such a mark can additionally be used as a control code for the Selection of the stored images are used for an image comparison.
- the angle of light on the identification area is set between 8 ° and 45 °, preferably between 12 ° and 35 °.
- the small amount of time required to extract and save an image allows for this method, both in the identification station and in the sorting station several Images of the same identification area with different light incidence directions and / or to gain light incidence angles and to store them in the database and to Increasing the reliability of identification in the identification according to the comparison method evaluate.
- by means of lighting body light from four sides with predetermined light incidence angles on the same identification surface are applied, wherein for each image, the light applied from another side becomes.
- the different shadows create four different ones Pictures of the same identification area.
- a light shield in the form of a small tunnel or to arrange a pipe is recommended according to another embodiment, at the identification station and at the sorting station.
- Typical features such as elevations or Recesses on the identification area are in this method according to the existing number of images obtained as optical identification features in the Comparative method available.
- Fig. 1 is a semi-finished product in the form of a strand section 2 on an identification table 3 shown.
- the strand section 2 is not in this example by means of a Diagonal scissors have been separated from the strand.
- a separation surface 4 shows Traces of shearing by the knife of the diagonal scissors. These traces on the Parting surface 4 are as visually recognizable features of the surface texture used for identification of the strand section 2.
- the entire Dividing surface used as identification area. For large cut surfaces, for example in slabs, but only parts of the cut surface as identification area be used.
- a first camera 6 is behind a slider-like movable heat shield 8 arranged and aligned on the identification area. Instead of the heat shield 8, the camera 6 may be arranged on a displacement device. to Illumination of the identification surface are with the camera 6 one or more lighting fixtures 9 connected. The intensity of the artificial light is measured that the light effect of the daylight is turned off.
- the digitized image of the first camera 6 is stored in the database 10.
- the Database 10 all identification data, in particular all quality-related Identification data of the monitoring system 12 of the continuous casting, supplied and the cut strand section 2 assigned.
- the one through the digitized image identified strand section 2 is then a sorting point for a subsequent Manufacturing process or fed to a temporary storage.
- a second digitized image is obtained with the second camera 14 and used in the database 10 for the identification of the strand section 2.
- the identification takes place in the database 10 by a comparison of the digitized Image of the second camera 14 with the digitized stored in the database 10 Pictures of the first camera 6.
- Such an auxiliary device can from a height-adjustable positioning device 49 for the strand section 2, from a connected to the camera distance measuring device or from a automatic focusing system integrated into a camera.
- FIG. 2 20 shows a strand section in a flame cutting station 21. through a flame cutter 22, a separating cut has been performed. Through the flame cut are optically on a cut surface 23 used as an identification surface identifiable identification features have been generated.
- markings 25 may consist of simple holes, Special characters, alphanumeric characters, barcodes or color samples, etc. exist. The task of such visually recognizable additional markers is diverse. They can, for example, represent distinguishing features for strand sections, which are recognizable by the human eye and pre-sortings, e.g. on one Storage space, allow.
- a marking device as in the prior art widely known is.
- a marking station or a subsequent identification station 28 is by means of a first camera 30 a digitized image of the cut surface 23 and recorded a database 31 supplied. This database also receives signals 32 of the marking device 26 and the relevant parameters 33 of the casting process monitoring 34.
- the strand section 20 a storage space 35 or be fed directly to a sorting station 36 for further processing.
- a second camera 38 digitalized images of the cut surface 23 won.
- the marks 25 indicate in this Example indicates that the strand section 20 in the sorting station 36 opposite the marking station 24 and the identification station 28 has arrived tilted by 180 °.
- the digitized images of the camera 38 are therefore also rotated by 180 ° in the Database saved for comparison evaluation. If through the comparison method the identification of the strand section 20 is completed, all relevant parameters the casting process with the identified strand section 20 of a process control 45 fed to a rolling mill.
- essentially shadowless lighting means the lighting fixtures 9, it is also possible, the light incident on the identification area to steer so that unevenness by shadows increasingly appear and thereby additional identification features are created.
- Fig. 2 by a light beam 40 and lighting fixture 41 a shown obliquely incident on the identification surface lighting.
- the selection of Location of the lighting, for example from above or from below, and the selection of a Lichteinfallswinkels 43 on the cutting surface 23 is used together with the digitized Image recorded in the database 31. If the strand section 20 hits, for example, in the Sorting station 36 tilted by 180 °, as shown in Fig. 2, so the incidence of light adjusted accordingly.
- the recording and storage of the digitized images in the database 31 is required only fractions of seconds.
- digitized images of the cut surface 23 successively with different light incidence angle 43 in the database store.
- With two or more digitized images the same sectional area 23, but with different light incidence direction is without significant loss of time increases the reliability of identification, without higher To cause costs.
- a shield 46 arranged against foreign light sources in the form of a tunnel or a tubular body.
- this shield 46 are light sources 41 on all four sides of the tunnel housed in niches 47. These niches are protected by flaps 48 for protection Heat radiation can be closed.
- the four light sources 41 allow successively four To win pictures, for each image the light from a different direction on the Identification surface is applied. By the different shadows everyone Light source arise four different images of the same identification area.
- the strand portion 20 in the shield 46 retracted and fixed against a stop 49, or the shield 46 moves together with the camera against the strand section.
- exact distance adjustment between the interface 23 and the camera 38 can also in this Embodiment of a known in the prior art distance measuring device or an automatic focusing system.
- Images stored in the database of the first camera used to identify a Strand section are marked in the database or from the database away.
