[0030] The specific implementation of the utility model is further described in detail below in conjunction with the drawings and embodiments.

[0031] like Figures 1 to 4 As shown, an embodiment of the present disclosure provides a paper machine winder alarm system for providing safety reminders to relevant personnel when they approach the winder. Wherein, the winder includes a step structure, and the step structure includes a horizontal step surface 100 and a vertical step surface 200 perpendicular to the horizontal step surface 100. The paper machine winder alarm system includes a prompt structure 10, a human body detection device 20, a light source prompt device 30, a pressure detection device 40 and a sound alarm 50. Wherein, the prompt structure 10 is arranged on the vertical step surface 200 for providing safety reminders. The human body detection device 20 is arranged on the front side of the winder. The light source prompt device 30 is arranged on the prompt structure 10 and is electrically connected to the human body detection device 20. The pressure detection device 40 is arranged on the horizontal step surface 100 for detecting the pressure on the horizontal step surface 100. The sound alarm 50 is electrically connected to the pressure detection device 40.

[0032] In the paper machine winder alarm system provided in this embodiment, a prompt structure 10 is provided on the vertical step surface 200 for safety prompts. When the human body detection device 20 on the front side of the winder detects a human body, the light source prompt device 30 connected to the human body detection device 20 and provided on the prompt structure 10 can remind the relevant personnel by emitting light, and when the human body steps on the horizontal step surface 100, the pressure detection device 40 can detect that the horizontal step surface 100 is under pressure, so that the sound alarm 50 can make further sound reminders. Through multi-level reminders, effective reminders can be provided to relevant personnel and the safety level can be improved. In addition, corresponding reminders will be given only when different situations are detected, which can effectively reduce energy consumption and avoid unnecessary power loss.

[0033] In one embodiment, if Figure 3 As shown, the prompt structure 10 includes a groove 11 arranged on the vertical step surface 200, and the groove 11 constitutes a text prompt and / or a pattern prompt. The light source prompt device 30 is embedded in the groove 11. The design of the groove 11 can not only realize the positioning of the light source prompt device 30, but also can well protect the light source prompt device 30.

[0034] The specific arrangement of the light source prompting device 30 is not limited. In one embodiment, the light source prompting device 30 is a light strip extending along the extension direction of the groove 11. In another embodiment, the light source prompting device 30 is a plurality of point light sources arranged at intervals along the extension direction of the groove 11.

[0035] In one embodiment, the adjacent point light sources have different luminous colors. In another embodiment, the luminous colors of the light source prompting device 30 corresponding to adjacent words in the text prompt are different. Different luminous colors can further improve the prompting effect on relevant personnel.

[0036] In one embodiment, if Figure 4As shown, the human body detection device 20 includes an infrared emitting unit 21 and an infrared receiving unit 22 which are arranged relatively, and the infrared receiving unit 22 is connected to the power supply line of the light source prompting device 30 through the first power-on delay disconnection device 60. The infrared emitting unit 21 emits an infrared signal, and the infrared receiving unit 22 receives the infrared signal emitted by the infrared emitting unit 21. When the relevant person passes by, the infrared signal will be blocked. When the infrared receiving unit 22 cannot receive the infrared signal, it sends a corresponding level signal to the first power-on delay disconnection device 60, so that the first power-on delay disconnection device 60 conducts the power supply line of the light source prompting device 30 so that the light source prompting device 30 emits light for prompting. At the same time, the first power-on delay disconnection device 60 delays disconnection, so that the light source prompting device 30 automatically turns off after emitting light for a period of time, so as to avoid the light source prompting device 30 continuously emitting light and causing waste of electric energy.

[0037] In one embodiment, the alarm system for the paper machine winder further includes a comparator 80, a first input end of the comparator 80 is connected to the pressure detection device 40, a second input end of the comparator 80 is connected to the controller 400 of the winder, and an output end of the comparator 80 is electrically connected to the sound alarm 50. The comparator 80 is used to compare the reference signal input by the controller 400 with the pressure signal detected by the pressure detection device 40, and when the pressure signal is greater than the reference signal, the comparator 80 outputs a corresponding level signal so that the sound alarm 50 emits a sound for reminder.

[0038] In one embodiment, the output end of the comparator 80 is connected to the power supply line of the sound alarm 50 through the second power-on delay disconnection device 70. When the relevant personnel step onto the horizontal step surface 100, the pressure detected by the pressure detection device 40 will increase, so that the pressure signal is greater than the reference signal, and the comparator 80 sends a corresponding level signal to the second power-on delay disconnection device 70, so that the second power-on delay disconnection device 70 conducts the power supply line of the sound alarm 50 so that the sound alarm 50 sounds a reminder. At the same time, the second power-on delay disconnection device 70 delays disconnection, so that the sound alarm 50 automatically turns off after a period of sound reminder, so as to avoid the light sound alarm 50 continuously emitting sound and causing waste of electric energy.

[0039] In one embodiment, a control cabinet 300 is provided on one side of the winder, and the sound alarm 50 is installed in the control cabinet 300. This facilitates the connection between the controller 400 in the control cabinet 300 and the sound alarm 50, and also enables the sound alarm 50 to be close to the winder, thereby providing effective sound reminders to relevant personnel.

[0040] In one embodiment, the sound alarm 50 includes a buzzer and / or a voice alarm.

[0041] It can be understood that the power supply can be disconnected with delay by setting the existing device of power-on delay disconnection. The main electronic components of power-on delay disconnection include time relay and power-on delay timer. Time relay is a relay that can delay the contact action for a certain time after the coil is energized, while power-on delay timer is an electronic component that can delay the circuit disconnection for a period of time after power failure. These components realize the delay function through internal counters and comparators.

[0042] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
