    INSTALLATION AND METHOD OF TANDEM ROLLER OUTPUT WITH COUPLED WINDING CARROUSEL WITH ONLINE INSPECTION (I)
    Object of the invention The present invention relates to an industrial installation and method relating to the technical field of metal strip rolling mills, in particular of the tandem type with continuous winding station, having at the end of rolling an inspection table of the rolled product and being wound.
    BACKGROUND ART AND STATE OF THE ART [0002] Tape winding by carousel tension coils, which we shall call more simply a carousel winding, is well known as a final rolling winding system, both at the rolling mill and at the rolling mill. cold than hot mill.
    The winding sequence is as follows: the carousel is in the receiving position with the belt winder raised around the mandrel No. 1 in the lower position, the free mandrel No. 2 being in the upper position at 180 °; - Once the tape is primed, the belt retractor retracts and the winding of the reel No. 1 continues; - while the winding continues, the entire carousel rotates 180 ° in the direction of clockwise if the band comes from the left (if not in the opposite direction), which places the coil No. 1 during winding in the evacuation position and the free mandrel in the receiving position for the front end of the next web to be wound; - At the end of the winding of the coil No. 1, the power is transferred to the mandrel No. 2. Coil No. 1 is evacuated and the next winding cycle begins.
    The embodiment details of the constituent means of the winding carousel such as the belt winder, the position of the mandrels, the device for supporting and evacuating the mandrels, etc. are well known to those skilled in the art.
    A problem that arises is to detect as early as possible in the manufacturing process defects that can be unacceptable for the rolled strip, such as surface defects, geometry, thickness, flatness, etc. . A separate inspection of the line is not possible because it is disadvantageous from the point of view of the loss of time and therefore from the economic point of view.
    [0006] JP 2000 254725 discloses a cold rolling plant comprising, mounted in this order on the line, a cold rolling mill, a movable shear which cuts the steel strip produced continuously by the rolling mill, an apparatus for double mandrel tension winding, of the carrousel winder type, which continuously coils the steel strip. The carousel winder is positioned downstream and below the cold rolling line and a surface inspection apparatus which inspects the surface of the steel strip, is located downstream on an extension of the line of pass that passes over the carousel coiler. The installation is provided with switching means for directing the strip towards the carousel reel or alternatively to the surface inspection apparatus, positioned outside the moving shear.
    EP 1 581 355 discloses a method for the successive rolling and winding of a metal strip, in particular a steel strip, on a winding mandrel driven in rotation and capable of being discarded, in which the metal strip is inspected in longitudinal portions with respect to rolling anomalies. The strip samples are produced by a drum shear located after the last rolling stand, guided and stopped "in line" inside the rolling line above a winding station located below the rolling line. rolling line, on an inspection table, for a free visual inspection.
    The winding station is located under the plane of the inspection table, the latter being arranged "in line" with the rolling line. Here again, the steel strip emerging from the last rolling stand can be guided so that a baffle unit, arranged at the entrance of the winding station, can deflect the metal strip towards a winding mandrel.
    [0009] Generally, the inspection table is provided with gripping means which make it possible to return the strip samples in order to also inspect the other face.
    In addition, after the inspection on the inspection table, the tape samples are routed to a shear which reduces them to pieces before collection by gravity in a bin or waste car.
    The solutions as described above have advantages over the separate offline inspection: short access time and fast inspection, use only a sample of the tape and therefore no need to remove a full reel material flow. However, they have the disadvantage of using a switching system or deflector.
    OBJECTS OF THE INVENTION [0012] The object of the present invention is to enable the realization of a rapid and inexpensive inspection of rolled metal strips in a continuous rolling mill, including the winding station.
    The invention also aims to achieve a simple and reliable installation to perform this inspection.
    In particular, the invention aims to provide a facility that does not have a switch to direct the band either to the winding carousel, or to the inspection table.
    Main Characteristic Elements of the Invention [0015] A first aspect of the present invention relates to a method for winding and inspecting a continuously laminated metal strip in line, comprising a step of continuously winding on at least one mandrel of a winding station, preferably a carousel, characterized by at least the following steps: the strip is cut by a first shear located before the winding, a last turn of the coil made pivoting about the axis of the chuck and falling on an introductory table lying in line with the line and followed by an inspection table; the strip advances a certain length on the introduction table and the inspection table and is cut by a second shear in order to obtain a sample; · - the sample is inspected on the inspection table for defects.
    According to preferred embodiments of the invention, the method comprises one or a suitable combination of the following steps: after obtaining the sample by action of the second shear, the strip is rewound back and the coil removed and evacuated from the winding station; - the tape sample is inspected on a first face, then returned and inspected on its second face; - after inspection, the sample is routed from the inspection table to an evacuation table, at the end of which is a third shear which cuts the sample into pieces which are then directed to a waste container or similar.
    A second aspect of the present invention relates to a winding installation and online inspection of a continuous rolled metal strip, comprising, downstream of the last roll stand, a first shear, a winding station on at least one mandrel and an inspection table for detecting defects on at least one face of the web, characterized in that the winding station and the inspection table are in line and in that the installation further comprises an introduction table located in line between the winding station and the inspection table, associated with a second shear, which makes it possible to produce a sample of determined length, once the band has been cut by the first shear, has pivoted about the axis of the mandrel by falling on the infeed table and advanced on the infeed table and the inspection table.
    [0018] Advantageously, the winding station is a carousel station.
    Still advantageously, the installation according to the invention comprises, at the inspection table, pliers gripping means that return the sample to inspect the other side.
    Brief Description of the Figures [0020] Fig. 1 shows a longitudinal sectional view of the carousel winding station coupled with an inspection table according to a preferred embodiment of the present invention.
    FIG. 2 represents a longitudinal sectional view of the carousel winding station, according to another section, parallel to that of FIG. 1.
    DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION [0022] A preferred embodiment of the installation according to the invention is shown in FIG.
    The installation comprises successively, at the exit of the last cage of the tandem mill, in the direction of movement of the metal strip (pass line 100):. a first shear 4; a carousel 3 equipped with a first upper right mandrel 10 for the manufacture of a spool 1, 1 ', 1' ', etc., provided with a nose-mandrel support 9, a second lower left mandrel 20 for making a coil 2, 2 ', 2' ', etc., provided with a nose-mandrel support 11 and a belt winder 5 for priming the winding on the lower mandrel; an introduction table 6; a second shear 7; an inspection table 8; clamping means 8 ', 8' 'of the strip sample, for the purpose of returning it; an evacuation table 12; a third shear 13; - a waste bin 14.
    The sequence of operations performed on this installation is described below. The order in which the operations are described below is not necessarily chronological.
    Step 1 c [0025] Firstly, the speed of travel of the web and the speed of rotation of the right and upper mandrel 10 are decreased.
    The strip of the coil called "No. 1" 1 (on the mandrel of the right and upper 10) is cut at the first shear 4, which generates a tail band.
    The coil called "No. 2" 2 begins to be wound on the chuck left and lower 20. Once a few turns are wound, the belt reel 5 used for priming the winding of the band is evacuated. The winding speed increases.
    At the end of the winding of the spool 1, the last turn, constituting the tail of the strip, pivots about the axis of the mandrel and "falls" on the introduction table 6. The tail of the spool 1 Y advance on the infeed table 6 and the inspection table 8. The tape tail of the spool 1 is then cut with the shear 7 to obtain a sample.
    The nose-mandrel support 9, supporting the right mandrel 10, is evacuated. The coil 1 is then rewound at the end of the band that has been cut at the sample. The "No. 1" coil 1 is then removed from the right mandrel 10 and discharged (with means not shown, known to those skilled in the art).
    The cut sample advances on the inspection table 8 and the sample is inspected on a first face. The ends of the sample are pinched by pinching means 8 ', 8' 'and the sample is returned (not shown). The other side of the sample is inspected. The ends of the sample are "peeled off". The sample advances on the evacuation table 12.
    Step 2, the nose-mandrel support 11, supporting the left mandrel 20, is evacuated and the carousel 3 rotates 180 ° in the direction of clockwise.
    Once the rotation of the carousel 3 is completed, the nose-mandrel support 9 is placed in position to support the new mandrel right and upper 10. The winding of the new coil "No. 2" 1 'continues so on the new right and upper chuck 10 (which is the old left chuck before rotation).
    The nose-mandrel support 11 is placed in position to support the new mandrel left and lower 20. The belt winder 5 used for priming the winding of the strip is set in the operating position.
    Step 3 [0034] The speed of travel of the web and the speed of rotation of the right and upper mandrel 10 are decreased.
    The strip of the coil "No. 2" 1 'is cut to the shear 4, which generates a tail band.
    The coil "No. 3" 2 'is wound on the chuck left and lower 10. Once a few turns are wound, the belt reel 5 is evacuated. The winding speed increases.
    At the end of the winding of the coil "No. 2" 1 ', the last turn, constituting the tail of the tape, falls on the introduction table 6. The tape tail of the coil 1' advance of Y meters. The tape tail of the coil 1 is cut with the shear 7 to obtain a sample which has been inspected as described above.
    The previous sample left the inspection table 8. At the end of the discharge table 12, the previous sample is cut into pieces about 1 meter long at the shear 13, where they are directed to the hopper 14.
