[0029] like Figures 1 to 5 As shown: A safety device for yarn storage personnel of a warp knitting machine, comprising:
[0030] A person detection component 1 is provided on the escalator 3 and includes two sensors 11. The two sensors 11 detect whether a person passes by on the escalator 3;
[0031] A control switch 2 is arranged on the side below the escalator 3 and is used to control the operation of the warp knitting machine, and two sensors 11 are electrically connected to the control switch 2;
[0032] When it is detected that a person passes by on the escalator 3, the control switch 2 turns off the operation of the warp knitting machine. When the control switch 2 is pressed, the warp knitting machine starts to run.
[0033] When the inspector needs to approach the warp feeding mechanism through the escalator 3 for inspection or maintenance, the sensor 11 of the personnel detection component 1 will detect the presence of the person and send a signal to the control switch 2. After receiving the signal, the control switch 2 will immediately shut down the warp knitting machine to prevent the machine from continuing to run when the inspector approaches, thereby eliminating potential safety risks. After the inspection and maintenance work is completed, the inspector can press the control switch 2 on the lower side of the escalator 3 to restart the warp knitting machine and resume normal production operations after walking down the escalator 3. This not only ensures the safety of the inspectors, but also improves the operating convenience and maintenance efficiency of the warp knitting machine, providing an effective solution for safety management in the textile production process.
[0034] In this embodiment, two sensors 11 are respectively disposed at the two ends of the escalator 3 to detect whether there is a person passing through the middle.
[0035] The component includes two sensors 11, which are respectively installed at the two ends of the escalator 3 to ensure that the passage of people can be accurately detected. When the sensor 11 detects that someone is passing on the escalator 3, the warp knitting machine is automatically shut down to ensure the safety of the people. By arranging sensors 11 at both ends of the escalator 3, accurate detection of the passage of people can be achieved, ensuring that the warp knitting machine automatically stops running when people approach.
[0036] As a preferred embodiment of the above embodiment, the two sensors 11 have the same height, are arranged on the railings at both ends of the escalator 3, and are arranged at a height of 0.5m to 1m from the bottom step plane of the escalator 3.
[0037] The two sensors 11 are set at the same height so that the detection area is consistent, thereby avoiding detection blind spots or errors caused by height differences, ensuring that people can be accurately detected when they pass through. The sensor 11 is set at 0.5m~1m from the bottom step plane of the escalator 3. This height range can cover the leg and waist activity areas of most adults, which is an ideal height for detecting people passing through. It will not be too low to be mistakenly triggered by obstacles, nor too high to cause missed detection. The sensor 11 is installed on the railing to ensure its fixity and stability, and it is not easy to move due to human operation or environmental changes, thereby maintaining long-term stable detection.
[0038] The personnel detection component 1 includes two mounting brackets 12 , and the two sensors 11 are fixedly mounted on the two mounting brackets 12 , respectively. The two mounting brackets 12 are fixedly mounted on the escalator 3 .
[0039] The mounting bracket 12 can provide additional protection and reduce the risk of damage to the sensor 11 due to accidental collision or vibration, thereby extending the service life of the sensor 11. By introducing the mounting bracket 12, this optimization solution not only improves the flexibility and stability of the installation of the sensor 11, but also simplifies maintenance work and enhances the reliability and service life of the system.
[0040] The mounting bracket 12 comprises:
[0041] The pipe clamp 121 is an annular structure and is fixedly mounted on the railing of the escalator 3. The pipe clamp 121 is provided with a mounting surface 1211 at one end perpendicular to the running direction of the escalator 3, and the sensor 11 is fixedly mounted on the mounting surface 1211;
[0042] The protective cover 122 is disposed outside the sensor 11 to protect the sensor 11 .
[0043] The annular structure of the pipe clamp 121 can be firmly fixed on the railing of the escalator 3 to ensure that the sensor 11 will not shift or loosen during operation. The pipe clamp 121 can adapt to escalator 3 railings of different diameters, providing a flexible installation solution so that the system can be applied to various types of escalators 3. The protective cover 122 effectively protects the sensor 11 from external physical damage, such as collision, scratching, etc., thereby extending the service life of the sensor 11. The structure of the pipe clamp 121 makes the installation and removal of the sensor 11 simple and quick, and maintenance personnel can easily perform regular inspections, cleaning or replacement of the sensor 11, saving time and labor costs. The design of the pipe clamp 121 and the mounting surface 1211 makes it easier to adjust the height and angle of the sensor 11 to adapt to different detection needs and environmental changes.
[0044] In this embodiment, the protective cover 122 includes an L-shaped structure, one end of which is fixedly disposed on the mounting surface 1211, and a receiving space is formed between the other end and the mounting surface 1211. The sensor 11 is located in the receiving space, and the protective cover 122 and the mounting surface 1211 form an opening on one side close to the middle of the escalator 3.
[0045] The L-shaped protective cover 122 provides a solid barrier, effectively protecting the sensor 11 from physical damage, such as collision and scratching. The protective cover 122 and the mounting surface 1211 form an opening on the side close to the middle of the escalator 3, ensuring that the detection range of the sensor 11 is not blocked and can accurately detect the passage of people on the escalator 3. The accommodating space design between the L-shaped protective cover 122 and the mounting surface 1211 makes the height and angle adjustment of the sensor 11 more flexible to adapt to different detection requirements and environmental changes.
[0046] The pipe clamp 121 is provided with an adjusting bolt 123 , and when the adjusting bolt 123 is tightened, the position of the pipe clamp 121 is fixed; when the adjusting bolt 123 is loosened, the position of the pipe clamp 121 can be adjusted.
[0047] The design of the adjustment bolt 123 allows the pipe clamp 121 to be adjusted according to actual needs during installation. The maintenance personnel can loosen the bolt, adjust the pipe clamp 121 to the ideal position, and then tighten the bolt to fix it. This flexibility ensures that the sensor 11 can be installed in the best position to cover the required detection area.
[0048] As a preference of the above embodiment, the sensor 11 is a photoelectric sensor 11, and the two sensors 11 transmit and receive signals to each other to form a grating. When the grating is blocked, a signal is sent out.
[0049] By introducing the photoelectric sensor 11, this optimization solution not only improves the detection accuracy and response speed, but also enhances the reliability and environmental adaptability of the system. At the same time, the non-contact detection method and flexible installation design of the photoelectric sensor 11 simplify the installation and maintenance process of the system, providing a more advanced and efficient solution for safety management in the textile production process.
