    The fault-finding processing for avoiding faults in material when cutting out pattern pieces is undertaken when laying out layers of material by comparing the relevant layer with the original cutting image on a scale of 1:1. In the event of a fault it can be detected whether this occurs in the material waste area so that it can be disregarded or whether it can be brought into the position by turning, rotating or displacing the relevant layer. This comparison is achieved using a comparison table which is mounted parallel to the cutting out table and contains an original pattern image with true co-ordinates. The comparison table also supports a measuring carriage which is rigidly coupled to the laying-out carriage, and is provided with a transversely displaceable television camera which stores the measured values.

    专利说明:

    The layout of the template layout consists of a table 4 installed parallel to the spreading table 1 and has two measuring lines 5 and b, located perpendicular / 1, one relative to the other and on which are installed, respectively, the 7 and 8 axes of the X and Y axes a recreational element made in the form of a carriage 9, carrying a television camera 10 mounted on a slider 11. The carriage 9 is rigidly connected to the carriage
    2dl material and with determinant
    3 defects of the material by means of connecting rods 12 and 13, and the material carriage 2 has a video monitoring device 14, and the determinant 3 of material defects contains a radiation source (not shown)
    Table 4 for the original, the layout of the templates is set at an angle not exceeding relative to the flooring table 1,
    The installation also has a drive 15 of the carriage 9 placed on the table 4 and the fixing indicators 16 and 17 are the same length L and width B of the laid material web.
    The installation works as follows.
    The length L and the width B of the laid material web are fixed on the indicators 16 and 17 coordinates. The camera 10 and the determinant of 3 material defects are above the coordinate overlap or above the unfolded original.
    When laying out the layer, the carriage 2 for the material and the measuring carriage 9 move to the left. At the same time, the 8 coordinate meter records the readings of the measuring line 6 and shows them in digital terms using the x-ray coordinates (difference coordinates) in the digital radiation source.
    If a defect is installed on the material web, then the carriage 2 stops at the corresponding X coordinate.
    By turning on the drive 15 of the carriage 2, the camera 10 moves in the transverse direction while the determinant 3 defects are rigidly connected by means of a connecting rod. 13 with the carriage 9, its optical axis will not be fixed above the defect. In this case, by means of the meter 7 coordinates, the indicators Y are fixed on the measuring ruler 5 and are shown in digital terms as the coordinates Y and V-Y on the pointer 15 coordinates. At this point, an image of the original appears on the video monitor 14, which is transmitted by the camera 10, the optical axis of which is shown on the video monitor 14,
    and allows to determine the position of the defect on the material web.
    From the position of the defect on the video monitor device 14, it is possible to determine how, by moving the web of material to the left or 1 right, the defect falls into the cutout of the model. The digital values of the required movement are counted at a predetermined scale, which is located on the video monitor.
    If it is not possible to get rid of the defect, then it is necessary to check what position this defect will occupy when the layer is turned. For this, the carriage 2 is placed in such a position that the pointer of the 16 coordinates shows the initial difference of coordinates. The left number must be equal to X 450.0 and the difference indicator X 150.0, tax as the total length in this example is chosen equal to bm. change their values. In this case, the determinant of 3 defects and the camera 10 are located above the point that the defect would occupy if the layer were turned 180 °.
    The shift indicators are counted on the video monitor 14.
    If elimination of the defect is not possible, then a notch is made and benign portions are used for minor operations.
    If the laid material web is treated in a similar way, then the carriage 2 returns to its original position and the whole operation begins with a new material web.
    Upon reaching the initial position, the coordinate system is installed at zero marks or at a set difference in length and width.
