[0002] Before producing C-shaped steel, the steel coil needs to be unwound according to the operating procedures. Due to the exposed fan blades and tightening and retracting cam parts of the unwinding machine, the coil rotates at high speed and may become loose or break. Once the operator approaches, he is very likely to be seriously injured, which poses a safety hazard and cannot meet the safety requirements. The existing safety protection measures have obvious defects. Traditional warning signs cannot effectively prevent people from entering the danger zone, and conventional fences are difficult to meet the complex and changeable working environment requirements of the unwinding machine in terms of structural strength, ease of use, and integrity of protection functions. Therefore, an innovative safety fence design is urgently needed to fill this technical gap and ensure safe and efficient production.

[0003] For example, a robot safety protection fence with an intelligent alarm function provided by announcement number CN109519689A includes a workpiece handling system and a safety protection control system; the workpiece handling system includes a palletizing robot, a control box, and a safety fence; the palletizing robot and the safety fence are both fixed on the ground, and the palletizing robot is installed inside the safety fence; the control box is connected to the palletizing robot; the safety protection control system includes a safety input module, a safety control module and a safety output module; the safety input module is used to detect whether there is a person approaching a dangerous source; the safety output module is used to output an alarm when the safety input device detects the presence of a dangerous source; the safety control module is used to read and calculate the detection information of the safety input device and control the safety output device; the robot safety protection fence with an intelligent alarm function of the present invention has a comprehensive installation training system, which is more in line with actual application scenarios.

By arranging the elastic plates 202, the cross bars 201 can have a certain elastic expansion space in the length direction. When the elastic blocking net 203 is hit, the cross bars 201 will be deformed and stretched through the elastic plates 202. At the same time, the connecting plates 204 can rotate relative to the cross bars 201 to further expand the deformation of the cross bars 201 and the elastic blocking net 203, so that a larger buffer can be obtained during the collision to avoid the hard collision of the coiled material fragments with the fence assembly, causing the fence assembly to break and splash directly.

[0036] When the above structure is in use, the fence assembly is aligned with the installation column 1 and the support base 205 is placed on the ground. At this time, the positions of the first connecting frame 401 and the second connecting frame 403 correspond, and the movable frame 402 and the first connecting frame 401 are staggered with each other. The advantage of such a design is that the first connecting frame 401 can be staggered with the second connecting frame 403 in the vertical direction without the need for more precise alignment. During assembly, the second connecting frame 403 is driven by the movable frame 402 to be sleeved on the surface of the first connecting frame 401. When all the first connecting frames 401 are respectively sleeved with the second connecting frames 403, the connection between the fence assembly and the installation column 1 is preliminarily completed.

[0037] The first connecting frame 401 is fixedly connected to one end of the two connecting plates 204 away from the surface, and the inner wall of the second connecting frame 403 and the surface of the first connecting frame 401 are roughened so that when the second connecting frame 403 drives the first connecting frame 401 to move horizontally, there is a large friction between the first connecting frame 401 and the second connecting frame 403 and it is not easy to move relative to each other. The movable frame 402 is a rectangular tubular structure with openings on the top and the bottom. The side wall of the mounting column 1 corresponding to the position of the movable frame 402 is provided with a third movable groove 421, so that the movable frame 402 moves to the internal position of the mounting column 1. The first driving frame 406 and the second driving frame 407 are respectively movable through and extend to the inside of the mounting column 1. The inner wall of the mounting column 1 corresponding to the position of the first driving frame 406 is rotatably provided with a first driving disk 408, and the inner wall of the mounting column 1 corresponding to the position of the second driving frame 407 is rotatably provided with a second driving disk 409. The first driving disk 408 corresponds to the first A first movable groove 410 is respectively provided in the middle of the driving frame 406 and the middle of the second driving disc 409 corresponding to the position of the second driving frame 407, and the first driving frame 406 and the second driving frame 407 are respectively movably connected to the inner wall of the first movable groove 410, the first driving disc 408 is located at the top of the second driving disc 409, the first driving frame 406 and the second driving frame 407 are symmetrically arranged, the inner walls of the mounting column 1 corresponding to the top and bottom positions of the first driving disc 408 and the second driving disc 409 are respectively fixedly connected with retaining frames 413, and the second driving disc 409 and the second driving disc 409 are respectively rotatably connected to the position between two vertically adjacent retaining frames 413, one end of the opposite surface of the first driving disc 408 and the second driving disc 409 are meshed with a bevel gear 411, the surface of the bevel gear 411 is rotatably connected with a fixed seat 412 through a bearing, and the fixed seat 412 is fixedly connected to the middle of the mounting column 1;

[0038] When the above structure is in use, when the first driving disk 408 rotates, the first driving disk 408 will drive the second driving disk 409 to rotate in the opposite direction through the bevel gear 411, and then the first driving disk 408 and the second driving disk 409 will respectively drive the first driving frame 406 and the second driving frame 407 to move toward the inside of the mounting column 1 through the first movable groove 410, and the first driving frame 406 and the second driving frame 407 will drive the movable frame 402 to move toward the inside of the mounting column 1, so that the movable frame 402 drives the first connecting frame 401 to move toward one end of the mounting column 1 through the second connecting frame 403, completing the assembly between the mounting column 1 and the fence assembly, thereby achieving the purpose of facilitating installation, and when disassembling, it is only necessary to separate the second connecting frame 403 from the first connecting frame 401, which is simple to operate and convenient to disassemble.

[0039] A driving shaft 414 is fixedly connected to the middle of the first driving disk 408, and the driving shaft 414 is rotatably connected to the middle of the second driving disk 409. The top and bottom of the driving shaft 414 are rotatably connected to the first fixing frame 415 through bearings. The first fixing frame 415 is fixedly connected to the inner wall of the mounting column 1. A plurality of second fixing frames 416 are fixedly connected to the middle of the inner wall of the mounting column 1, and the second fixing frames 416 are rotatably connected to the surface of the driving shaft 414 through bearings. A driving arc tube 417 is fixedly connected to the surface of the driving shaft 414 corresponding to the position of the second fixing frame 416 in the middle. The second fixing frames 416 correspond to A notch is provided at one end of the driving arc tube 417 to provide space for the rotation of the driving arc tube 417. The second fixed frame 416 and the movable frame 402 are both made of magnetic materials. A driving arm 418 is hingedly connected to one end of the second fixed frame 416 corresponding to the driving arc tube 417. A spiral driving groove 419 is provided on the side wall of the driving arc tube 417 corresponding to the driving arm 418, and the driving arm 418 is movably connected to the inner wall of the driving groove 419. A second movable groove 420 is provided on the side wall of the fence assembly corresponding to the driving arm 418, and the driving arm 418 is movably connected to the inner wall of the second movable groove 420.

[0040] When the above structure is in use, the driving arm 418 is rotated upward so that the driving arm 418 is hinged to the second fixed frame 416 and swings upward. Since the driving groove 419 is a spiral structure, when the driving arm 418 swings upward, it moves upward on the inner wall of the driving groove 419 and drives the driving arc tube 417 to rotate through the driving groove 419, thereby causing the driving arc tube 417 to rotate and causing the driving shaft 414 to rotate, thereby causing the driving shaft 414 to drive the first driving disk 408 to rotate.

[0041] Working principle: When installing the invention, first align the fence assembly with the installation column 1, and make the support base 205 fall to the ground. At this time, the positions of the first connecting frame 401 and the second connecting frame 403 correspond. Since the movable frame 402 and the second fixed frame 416 are both magnetic material components, the movable frame 402 is respectively adsorbed on the top and bottom of the second fixed frame 416 in the initial position, and staggered with the first connecting frame 401. The advantage of this design is that the first connecting frame 401 can be staggered with the second connecting frame 403 in the vertical direction without the need for more precise alignment.

[0042] During assembly, the movable frame 402 is driven to move along the direction of the third movable groove 421, the first guide rod 404 and the second guide rod 405, and the movable frame 402 drives the second connecting frame 403 to be sleeved on the surface of the first connecting frame 401. When all the first connecting frames 401 are respectively sleeved with the second connecting frames 403, the connection between the fence assembly and the installation column 1 is preliminarily completed;

[0043] By rotating the driving arm 418 upward, the driving arm 418 is hinged to the second fixing frame 416 and swings upward. Since the driving groove 419 is a spiral structure, when the driving arm 418 swings upward, it moves upward on the inner wall of the driving groove 419 and drives the driving arc tube 417 to rotate through the driving groove 419, thereby causing the driving arc tube 417 to drive the driving shaft 414 to rotate, and the driving shaft 414 drives the first driving disk 408 to rotate. When the first driving disk 408 rotates, the first driving disk 408 drives the second driving disk 409 to rotate in the opposite direction through the bevel gear 411, thereby causing the first driving disk 408 and the second driving disk 409 to drive the first driving frame 406 and the second driving frame 407 to move toward the inside of the mounting column 1 through the first movable groove 410, and the first driving frame 406 and the second driving frame 407 are respectively driven ... 07 drives the movable frame 402 to move inside the installation column 1, so that the movable frame 402 drives the first connecting frame 401 to move toward one end of the installation column 1 through the second connecting frame 403, completing the assembly between the installation column 1 and the fence assembly, thereby achieving the purpose of facilitating installation, and when disassembling, it is only necessary to rotate the driving arm 418 downward, so that the first driving disk 408 and the second driving disk 409 drive the movable frame 402 away from the installation column 1 through the first driving frame 406 and the second driving frame 407, and then separate the second connecting frame 403 from the first connecting frame 401, which is simple to operate and convenient to disassemble. The side wall of the installation column 1 corresponding to the position of the driving arm 418 is provided with a limiting structure for positioning the driving arm 418 (not shown in the figure), so that the driving arm 418 can maintain an upward tilted setting, that is, maintain the connection structure between the installation column 1 and the fence assembly;

[0044] The elastic plate 202 is provided so that the cross bar 201 can have a certain elastic expansion space in the length direction, and the elastic blocking net 203 is used to make the fence assembly itself have a certain elastic force. When the elastic blocking net 203 is hit, the cross bar 201 is deformed and stretched through the elastic plate 202, and the connecting plate 204 rotates relative to the cross bar 201, further expanding the deformation of the cross bar 201 and the elastic blocking net 203, so that a larger buffer can be obtained during the collision, thereby preventing the coil fragments from colliding hard with the fence assembly, causing the fence assembly to be directly broken and splashed;

[0045] When the installation column 1, the fence assembly and the fence door 3 are completed, when the staff opens the safety interlock 5 to enter the uncoiler working space, the uncoiler is in a power-off state, which effectively protects the personal safety of the staff. The laser scanner 6 is designed to monitor the uncoiler working space in a 270° range. When a staff appears within the monitoring range, an alarm is issued in time and the power supply of the uncoiler is urgently cut off, thereby preventing accidents from happening to the staff.
