Description

[0001] DETECTING AND REFLECTING SYSTEM THE DEFECTIVE PART IN THE SPREADING MACHINE

[0002] TECHNICAL FIELD

[0003] The invention relates to a system that enables flexible materials to stop automatically when a defect label is detected on them while spreading in layers, reflects the pastal plan and reflects it by digital marking, making it easier to determine the location of the part where the defect is located and to determine the splice location accordingly.

[0004] PRIOR ART

[0005] In the case of flexible materials, the splice determination is done manually by personnel or automatically by the machine, and the decision to go to the splice is always made by the personnel. While the newly developed spreading machines in the known art can perform the splice determination automatically when the material ball is finished, staff make the decision to go to the additional location.

[0006] Splice location detection in defective material is carried out by printing a label or tape at the level of the defect, processing them with the help of at least one of the camera and sensor, stopping the spreading at the location of the defect and projecting the marker plan on it. In this way, it is determined whether the defect coincides with a part on the pastal plan. The projection is done by a projection device connected to the spreading table.

[0007] In the known technique, the projection device is connected to the dissemination table, which requires a separate projection device for each table, resulting in a separate cost.

[0008] The height of the material increases as it is spread, so existing systems have a projection device that can move vertically so that the projected area remains within the limits of the spread material. Since a movement mechanism is required for vertical movement and components are required to provide the movement, the cost increases and the system cannot optimize itself.

[0009] The lengths of flexible materials spread on spreading tables of a certain length can vary. For this reason, as the length of the emitted pastal increases, issues such as the alignment of the pastal plan image projected by the projection device, the closest realization of the image and its resolution are uncertain.

[0025] DETAILED DESCRIPTION OF THE INVENTION

[0026] The invention relates to a system that enables flexible materials to stop automatically when a defect label is detected on them while spreading in layers, and facilitates the determination of the location of the part where the defect is located by projecting the marker plan and digital marking, and the determination of the joint accordingly.

[0027] The invention basically consists of a flexible material (1 ) in roll form, such as fabric, technical textile, etc., on which defect control is performed, a spreading machine (2) on which the roll material is placed and which allows it to be spread in layers, a spreading table (3) on which the material is spread, at least one of the label detection sensor (4.1 ) and camera (8) indicating the location of the defect on it, a projection device (5) projecting the marker plan to the area where the defect is located, a data processing center (6) that enables the processing of the defect label image detected by the label detection sensor (4. 1 ) and the data processing center (6), which processes the defect label image detected by the camera (8) and communicates with the projection device (5), the flexible material spread in layers (7), the marker position sensor (4.2) on the spreading table (3) and the encoder (9) that detects the number of layers. At least one component with a function such as a computer, tablet and the like is used as the data processing center (6).

[0028] An identifying label is printed on the flexible material (1 ) at the location of the defect by means of at least one of the manual and automatic inspection machines. The inspected flexible materials such as fabric (1 ) are rolled into rolls and placed on the spreading machine (2). The rolled flexible material (1 ) placed in the spreading machine (2) is spread on the spreading table (3) in certain lengths in layers.

[0029] The labels, which are printed on the defective area on flexible materials (1 ) such as fabrics, etc. by the inspection machine or manually, are detected by at least one of the label detection sensor (4.1 ) and camera (8) on the spreading machine (2) while spreading the flexible materials (1 ), and the location information is processed by communicating with the PLC. The location information processed by the PLC is transferred to the projection device (5) with algorithms developed by the data processing center (6). When the label containing the defect information on the flexible material (7) spread on the spreading table (3) by the spreading machine (2) upon detection of the label position by the data processing center (6), is at a distance where the projection device (5) starts to project the spreading process is stopped when the label containing. In addition, the defect location information is also used during fabric inspection after cutting.

[0030] When the defect is detected, the marker plan image is projected by the projection device (5) onto the flexible material (7), which is spread in stopped layers. This is done by projecting the parts of the marker plan in the line where the defect is located; in particular, the line where the defect is located is indicated with a different color and digital marking is made on it, which facilitates the location of the defect. Thus, whether the defect coincides with any part of the marker plan on the material is determined by the developed algorithm, and the personnel go to the joint with software support. In the event that the defect coincides with any part on the marker plan, the personnel who detect the joint with the developed software perform the material spreading process only in an area as much as the part where the defect coincides. Therefore, the amount of waste given for the material is reduced.

[0031] The projection device (5) is fixed on the spreading machine (2). The projection device (5), which is fixedly positioned on the spreading machine (2) and moves synchronously with it throughout the laying, does not require an extra motion assembly. In this way, the extra cost for the movement parts is avoided. The spreading machine (2) can work with more than one spreading table (3). Therefore, the spreading machine (2) is not required for each spreading table (3). Therefore, since the projection device (5) is connected to the spreading machine (2), the projection device (5) is also not required for each spreading table (3).

[0032] The data processing center (6) obtains the pastal size information of the spread flexible material (7) from the ERP systems of the companies and from the CAD files where the marker designs are made. The data processing center (6) obtains the position of the spread flexible material (7) on the spreading table (3) from at least one marker position sensor (4.2) in the spreading machine (2). Accordingly, the correct placement and optimization of the image on the spread flexible material (7) with different widths and lengths is ensured by the projection device (5). In this case, the placement of the image is optimized not by the motion mechanism, but by the software developed. As the flexible material (1 ) is spread on the spreading table (3) in layers, the image projected by the projection device (5) has the ability to protrude beyond the spread flexible material (7) due to the increase in the number of layers. Therefore, the distance between the minimum and maximum height positions at which the spreading machine (2) will start spreading the flexible material (1 ) as the number of layers increases is known. As the number of layers of the spread flexible material (7) increases, the amount of layer height is transmitted to the computing center (6) via an encoder (9), where algorithms are developed. Flexible material spread on the spreading table (3) of the projection device (5) with these algorithms the image size projected onto (7) is optimised by the encoder (9) by enlarging and reducing the size of the image according to the increasing layer height and pastal size, and is precisely positioned on the spread flexible material (7) with high resolution. This results in an improvement in the resolution quality of the projected image. Thus, the problems in existing systems where the projection device (5) is connected to the spreading table (3) are solved with the algorithms developed with the data processing center (6) in our system .

[0033] While the spread flexible materials (7) are checked at the sorting tables after they are cut, the joint and defective part information on them are obtained from the algorithms developed in the data processing center (6). The information on the seam determined on the material and the information on which part and on which floor of the flexible material (7), which is spread from the beginning instead of the defective part, is transmitted to the sorting tables by the data processing center (6). The personnel only remove the defective part from the pastal and do not detect a defect again.
