Description

Technical Field

[0001] The invention relates to the field of coil feeders, and in particular to safety warning equipment for coil feeders. Background Art

[0002] The safety warning device for coil feeders is usually installed inside the equipment. In an emergency, if the coil is found to be stuck, causing abnormal operation of the equipment, abnormal noise or other safety hazards, the operator can quickly press the emergency stop button to stop the equipment and prevent accidents.

[0003] At present, there are many drawbacks in the safety warning equipment for coil feeders on the market. These problems have brought adverse effects on the safety, stability and cost-effectiveness of production operations. On the one hand, most traditional safety warning equipment has a relatively simple detection method. For example, the common ones only rely on light curtain sensors. Although they can play a certain warning role in personnel intrusion into dangerous areas, when faced with complex mechanical failures such as foreign objects getting stuck, once foreign objects get stuck in the feeder, it is impossible to detect and take measures in time, which can easily cause foreign objects to splash, making on-site workers face the risk of being injured by high-speed splashing foreign objects, which seriously threatens personal safety.

[0004] On the other hand, traditional equipment lacks accurate and coherent protection mechanisms. They often rely solely on electrical circuits to control power outages. When a fault occurs, due to the single link, as long as there is a slight fault in the electrical circuit, the entire power-off protection will fail, and the equipment will continue to operate abnormally, which will not only accelerate the wear of the equipment itself and shorten its service life, but also cause more serious mechanical failures due to long-term abnormal operation, and even cause catastrophic consequences such as fire, bringing huge economic losses to the company. Finally, traditional equipment has poor fault tracing capabilities, and general fault detection methods require large-scale investigations, resulting in extended equipment downtime.

[0005] Secondly, traditional equipment relies on fuses to deal with short-circuit conditions in terms of short-circuit response speed. However, the working principle of the fuse determines that it requires the short-circuit current to accumulate to a certain level and for a specific period of time to cause the fuse to melt before the circuit can be cut off. In this process, the short-circuit current continues to impact the electrical components inside the equipment without hindrance, which can easily cause serious consequences such as burning of motor windings and damage to controller chips, greatly increasing equipment maintenance costs and downtime, and seriously affecting production progress.

[0006] In addition, the power cut-off method is too rough. It is common to directly disconnect the main circuit switch. This seems simple and direct, but in fact, the "one-size-fits-all" approach has many hidden dangers. Once the main switch trips, the entire feeder system will instantly fall into a state of complete power outage. Not only will the auxiliary equipment such as the coil tension adjustment device and the conveyor belt drive motor that are in operation come to an abrupt halt, but the control system connected to it will also be forced to shut down. As a result, when the equipment is restarted, a lot of time will be required to reinitialize each system. The process of resuming production is cumbersome and complicated, which greatly reduces production continuity and increases the company's operating costs.

[0007] In addition, traditional equipment has weak arc handling capabilities. When an arc is generated when the circuit is cut off, most traditional equipment can only allow the arc to cool and dissipate naturally in the air. This method is extremely inefficient, and the residual arc wanders around. On the one hand, it is easy to erode the insulation layer of electrical equipment. Over time, the insulation performance is greatly reduced, laying the root cause for frequent short-circuit failures in the future. On the other hand, if the free arc accidentally contacts other conductive components, it is easy to cause a new short-circuit point, causing the equipment to fall into a more dangerous failure cycle, seriously endangering the personal safety of on-site operators and the integrity of the equipment.

[0008] Finally, the coordination between mechanical and electrical protection is poor. Traditional early warning equipment either focuses on pure electrical protection, such as relying solely on leakage protectors to monitor leakage; or is limited to simple mechanical emergency stops, such as only setting an emergency stop button on the operating panel. There is a lack of effective linkage and coordination between the two. Once a complex short-circuit fault scenario occurs, it is difficult for mechanical protection to fill in in time when electrical protection fails, or the electrical system cannot provide accurate feedback after the mechanical protection is activated, and a comprehensive protection system cannot be formed, resulting in numerous protection loopholes in the equipment when facing emergencies, and a sharp increase in safety risks.

[0009] Therefore, it is necessary to provide a safety warning device for a coil feeder, aiming to solve the above problems. Summary of the invention

[0010] In view of the deficiencies in the prior art, an object of the present invention is to provide a safety warning device for a coil feeder.

[0011] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a safety warning device for a coil feeder, comprising a feeder housing and a feeding group, the feeding group being arranged at the top of the feeder housing, the top of the feeder housing being provided with a safety component for preventing the equipment from short-circuiting and causing safety problems, an anti-stuck component being provided above the safety component for preventing the feeding group from causing safety accidents due to jamming, and a trigger component for cooperating with the anti-stuck component being provided above the feeding group.

[0012] Preferably, the safety component includes a protective shell, which is arranged on the top of the feeder housing, a positioning plate is fixedly connected to the inside of the protective shell, a triangular power transmission plate is fixedly connected to the bottom of the positioning plate, a striker column is slidably connected to the top of the positioning plate, and a first return spring is fixedly connected between the striker column and the positioning plate.

[0013] Preferably, the safety component also includes a magnetic coil, which is sleeved on the outside of the striker column and the first return spring, the bottom of the protective shell is rotatably connected to a conductive plate, the bottom of the conductive plate is fixedly connected to a second return spring, the end of the second return spring away from the conductive plate is fixedly connected to a power-off paddle, and the power-off paddle is rotatably connected to the bottom of the protective shell, and the top of the inner cavity of the protective shell is fixedly connected to an arc extinguishing chamber.

[0014] Preferably, the anti-stuck material assembly includes an airbag tube, which is clamped on the top of the protective shell, and the top of the airbag tube is fixedly connected to a heat transfer rod in a ring-shaped arrangement, and the bottom of the heat transfer rod is fixedly connected to a sealing tube.

[0015] Preferably, the anti-stuck material assembly also includes a heating plate, and the heating plate is fixedly connected to the top of the protective shell, and an alarm light is fixedly connected to the top of the feeder shell.

[0016] Preferably, the trigger assembly includes a positioning block group, the positioning block group is fixedly connected to the top of the feeder housing, and the positioning block group is arranged above the feeding group, the positioning block group is internally rotatably connected to a driving rod, and the driving rod is slidably connected to the interior of the positioning block group, the positioning block group is internally slidably connected to an arc-shaped limiting block, and the arc-shaped limiting block and the positioning block group are fixedly connected to a third reset spring.

[0017] Preferably, the trigger assembly also includes a first conductive sheet group, the first conductive sheet group is fixedly connected to both ends of the driving rod, the interior of the positioning block group is fixedly connected to a second conductive sheet group, and the second conductive sheet group is arranged above the first conductive sheet group.

[0018] Preferably, the device uses a power supply composed of a magnetic coil, a triangular power transmission sheet, a conductive plate, and an alarm light to form a circuit path.

[0019] Preferably, the first conductive sheet group is electrically connected to a power source used by the device, and the second conductive sheet group is electrically connected to a heating sheet.

[0020] Preferably, the airbag tube is arranged above the striker column, the sealing tube is arranged inside the airbag tube, and sodium azide is arranged inside the sealing tube.

[0021] Compared with the prior art, the safety warning device for the coil feeder provided by the present invention has the following beneficial effects: 1. Through the setting of the anti-stuck component and the trigger component, when foreign objects are stuck during the coil feeding process, there will be foreign objects splashing and abnormal operation of the equipment, which will affect the safety of the staff. In this process, the foreign objects will resist the driving rod, so that the driving rod drives the first conductive sheet group and the second conductive sheet group to break away from the conflict, and finally the heating sheet triggers the sodium azide inside the sealing tube through the heat transfer rod, and finally the airbag tube drives the striker column to resist the power-off paddle, so that the equipment is powered off, and the alarm light goes out, so as to ensure the personal safety of the staff; Among them, compared with the single sensor detection method relied on by the traditional coil feeder safety warning equipment, the above structure builds a chain reaction mechanism starting from the foreign body hitting the driving rod. When the foreign body is stuck and causes the driving rod to move under force, the first conductive sheet group and the second conductive sheet group are instantly driven out of contact. This method based on mechanical transmission and conductive sheet linkage has an extremely fast reaction speed, and the subsequent protection process is started at the moment when the foreign body has just caused an impact, thus avoiding the time for the dangerous situation to further deteriorate. In addition, compared with traditional equipment, there is a lack of effective triggering protection for fault points that are hidden deep and not easily detected by conventional sensors. The above-mentioned precise heating using the heating plate ensures that in a specific fault scenario, that is, after a foreign object gets stuck in the drive rod and triggers a series of chain reactions, the heat is accurately transmitted to the sealing tube to activate sodium azide. Sodium azide is stable in nature, but once accurately triggered, it will react quickly to provide power for the subsequent airbag tube to drive the striker column to resist the power-off paddle. The entire process is precisely controlled to avoid false triggering. Compared with the one-size-fits-all power-off method of traditional early warning equipment, it is more intelligent. Compared with the general fault detection of traditional equipment, the above structure can quickly locate the problem caused by foreign objects being stuck by checking the position of the drive rod, the contact status of the conductive sheet group, etc. after an accident occurs, which makes it easier for maintenance personnel to accurately find the root cause of the fault, shorten maintenance time, reduce maintenance costs, and improve the operating stability of the entire coil feeding system.

[0022] 2. Through the setting of the safety component, when a short circuit occurs in the equipment, the rapidly increasing current will pass through the magnetic coil to cause the striker column to quickly compress the first reset spring, and at the same time, the striker column will quickly resist the power-off paddle, causing the power-off paddle to resist the conductive plate and quickly separate from the triangular power transmission plate, thereby achieving the purpose of quickly cutting off the power supply of the equipment, and the arc generated by the separation of the conductive plate and the triangular power transmission plate will flow to the arc extinguishing chamber for consumption, further improving the safety of the equipment; Among them, compared with the situation that the traditional coil feeder safety warning device only relies on the fuse to cut off the current in the face of a short circuit, because the fuse needs the current to reach a certain threshold and a certain period of time for the fuse to melt before it can work, during which the short-circuit current continues to impact the equipment and damage the electrical components, in contrast, once a short circuit occurs in the above structure, the rapidly increasing current instantly passes through the magnetic coil, and uses the electromagnetic force to drive the striker column to move, almost instantly compressing the first return spring and resisting the power-off paddle, so as to achieve the rapid separation of the conductive plate and the triangular transmission plate, greatly shortening the time from the occurrence of the short circuit to the power cut-off, effectively protecting the core components of the equipment from long-term high current impact, and reducing the risk of equipment damage; In addition, the traditional equipment has a relatively rough way of cutting off the power supply. For example, directly cutting off the main circuit switch will cause the entire feeder system to suddenly lose power, and some auxiliary equipment and control systems that are in operation will also be shut down, which is not conducive to the subsequent rapid restart and recovery of the equipment. The above structure accurately locates the key transmission link between the conductive plate and the triangular transmission plate, and only separates it. While cutting off the source of the short-circuit current, it ensures the relative stability of other circuits that are not related to the short circuit. After the fault is eliminated, only this link needs to be restored to quickly restart the feeder, thereby improving production continuity. Finally, traditional equipment mostly relies on natural air cooling to dissipate arcs, which is inefficient. Residual arcs can easily cause secondary electrical faults, such as damage to the electrical insulation layer and new short-circuit points. The above-mentioned structure is specially equipped with an arc extinguishing chamber. When the conductive plate is separated from the triangular transmission plate and an arc is generated, the arc is guided to the arc extinguishing chamber. The special materials and structures in the arc extinguishing chamber are used to consume the arc energy and extinguish the arc, fundamentally eliminating the potential hazards caused by the arc and creating a safer electrical environment for equipment operation.

[0023] In addition, traditional early warning equipment is usually a simple electrical protection or a simple mechanical emergency stop, and the two lack deep coordination. The new structure closely combines the mechanical action of the electromagnetic force generated by the magnetic coil to drive the striker column with electrical components such as the conductive plate and the triangular transmission plate, so as to mechanically drive the electrical cut-off, and the electrical feedback ensures the continuous and stable mechanical action (such as the first reset spring ensures the accuracy of the reset of the striker column and ensures the reliable action of the power-off paddle), forming an organic protection whole. It can better cope with complex and changeable short-circuit fault scenarios than a single protection mode, and comprehensively improve the safety of equipment.

[0024] 3. Through the setting of safety components, anti-stuck components and trigger components, the equipment will automatically cut off the power when a short circuit or foreign object jam occurs in the coil feeder, and the alarm light will automatically go out. Compared with the traditional coil feeder's safety warning device, which has a single function and cannot take into account different types of fault monitoring such as short circuit and foreign object jamming at the same time, the above structure realizes the simultaneous and accurate monitoring of these two faults.

Therefore, they should not be understood as limitations on the present invention.

[0029] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0030] Implementation example Figures 1 to 9 As shown, a safety warning device for a coil feeder provided by an embodiment of the present invention includes a feeder housing 11 and a feeder group 12. The feeder group 12 is arranged on the top of the feeder housing 11. A safety component for preventing a short circuit in the equipment from causing a safety problem is arranged on the top of the feeder housing 11. An anti-stuck component for preventing the feeder group 12 from causing a safety accident due to a jam is arranged above the safety component. A trigger component for cooperating with the anti-stuck component is arranged above the feeder group 12.

[0031] The safety component includes a protective shell 21, which is arranged on the top of the feeder housing 11. A positioning plate 22 is fixedly connected to the inside of the protective shell 21, a triangular power transmission plate 23 is fixedly connected to the bottom of the positioning plate 22, a striker column 24 is slidably connected to the top of the positioning plate 22, and a first return spring 25 is fixedly connected between the striker column 24 and the positioning plate 22.

[0032] The safety component also includes a magnetic coil 26, which is sleeved on the outside of the striker column 24 and the first return spring 25. The bottom of the protective shell 21 is rotatably connected to a conductive plate 27, and the bottom of the conductive plate 27 is fixedly connected to a second return spring 28. The end of the second return spring 28 away from the conductive plate 27 is fixedly connected to a power-off paddle 29, and the power-off paddle 29 is rotatably connected to the bottom of the protective shell 21, and the top of the inner cavity of the protective shell 21 is fixedly connected to an arc extinguishing chamber 210.

[0033] The anti-stuck material assembly includes an airbag tube 31, which is clamped on the top of the protective shell 21. The top of the airbag tube 31 is annularly distributed and fixedly connected to a heat transfer rod 32, and the bottom of the heat transfer rod 32 is fixedly connected to a sealing tube 33.

[0034] The anti-jamming component also includes a heating plate 34 , which is fixedly connected to the top of the protective shell 21 , and an alarm light 35 is fixedly connected to the top of the feeder housing 11 .

[0035] The trigger assembly includes a positioning block group 41, which is fixedly connected to the top of the feeder housing 11 and is arranged above the feeding group 12. The positioning block group 41 is internally rotatably connected to a drive rod 42, and the drive rod 42 is slidably connected to the inside of the positioning block group 41. The positioning block group 41 is internally slidably connected to an arc-shaped limiting block 43, and the arc-shaped limiting block 43 and the positioning block group 41 are fixedly connected to a third reset spring 44.

[0036] The trigger assembly also includes a first conductive sheet group 45 , which is fixedly connected to both ends of the driving rod 42 . A second conductive sheet group 46 is fixedly connected inside the positioning block group 41 , and the second conductive sheet group 46 is disposed above the first conductive sheet group 45 .

[0037] The power supply of the device is composed of a circuit path formed by the magnetic coil 26, the triangular power transmission sheet 23, the conductive plate 27, and the alarm light 35, so that when the triangular power transmission sheet 23 and the conductive plate 27 stop conflicting with each other, the device is powered off and the alarm light 35 is automatically extinguished.

[0038] The first conductive sheet group 45 is electrically connected to the power supply of the device, and the second conductive sheet group 46 is electrically connected to the heating sheet 34 , so that when the first conductive sheet group 45 and the second conductive sheet group 46 are in contact with each other, the heating sheet 34 is energized and generates heat.

[0039] The airbag tube 31 is arranged above the striker column 24, and the sealing tube 33 is arranged inside the airbag tube 31. Sodium azide is arranged inside the sealing tube 33, so that the sodium azide in the sealing tube 33 can rapidly expand the volume of the airbag tube 31 and trigger the striker column 24 to move.

[0040] Working principle: In the initial state, the triangular power transmission plate 23 is in conflict with the conductive plate 27, the first return spring 25 and the third return spring 44 are not compressed, the second return spring 28 is not stretched, and the first conductive plate group 45 is not in conflict with the second conductive plate group 46.

[0041] During operation, when the feeder housing 11 is transporting the coil, the feeder group 12 will drive the coil to move through the driving rod 42. If foreign matter is mixed into the feeder housing 11 at this time, the feeder group 12 will squeeze the foreign matter in the process of driving the coil to move, thereby causing the foreign matter to splash, which poses a certain safety hazard to the workers near the equipment. When a foreign object is rolled into the space between the feeding group 12 and the coil, the driving rod 42 will squeeze the foreign object, causing the driving rod 42 to rise along the inside of the positioning block group 41, and at the same time, both ends of the driving rod 42 will resist the arc-shaped limiting block 43 and rise synchronously, and the arc-shaped limiting block 43 will gradually compress the third return spring 44 while sliding along the inside of the positioning block group 41; When the driving rod 42 ascends along the inside of the positioning block group 41, the driving rod 42 drives the first conductive sheet group 45 to gradually collide with the second conductive sheet group 46. Since the first conductive sheet group 45 is electrically connected to the power supply of the device, and the second conductive sheet group 46 is electrically connected to the heating sheet 34, the heating sheet 34 is energized and generates heat when the first conductive sheet group 45 and the second conductive sheet group 46 collide with each other. When the heating plate 34 is powered on and heated, the heating plate 34 transfers heat to the inside of the sealing tube 33 through the heat transfer rod 32. Since sodium azide is arranged inside the sealing tube 33, the high-temperature heat transfer rod 32 reacts with the sodium azide, thereby rapidly decomposing the sodium azide. After the sodium azide is decomposed, a large amount of nitrogen is generated inside the airbag tube 31. Then, the nitrogen rapidly expands the volume of the airbag tube 31. The airbag tube 31 is arranged above the striker column 24, and then the airbag tube 31 moves against the striker column 24. Then, the striker column 24 descends along the bottom of the positioning plate 22, and the striker column 24 gradually compresses the first return spring 25. In the process of the striker column 24 descending along the positioning plate 22, it will resist the power-off paddle 29 to rotate, and the power-off paddle 29 will paddle the conductive plate 27 and the triangular power transmission plate 23 to gradually separate. Because the power supply of the equipment is composed of a circuit path formed by the magnetic coil 26, the triangular power transmission plate 23, the conductive plate 27, and the alarm light 35, when the triangular power transmission plate 23 and the conductive plate 27 stop conflicting with each other, the equipment is powered off and the alarm light 35 is automatically extinguished, thereby ensuring the personal safety of the staff; Compared with the traditional coil feeder safety warning device, the above structure constructs a chain reaction mechanism starting from the foreign object hitting the driving rod 42. When the foreign object is stuck and causes the driving rod 42 to move under force, the first conductive sheet group 45 and the second conductive sheet group 46 are instantly driven out of contact. This method based on mechanical transmission and conductive sheet linkage has an extremely fast reaction speed. The subsequent protection process is started at the moment when the foreign object has just caused an impact, avoiding the time for the dangerous situation to further deteriorate. At the same time, the whole process is precisely controlled to avoid false triggering. Compared with the one-size-fits-all power-off method of traditional warning equipment, it is more intelligent. Compared with the general fault detection of traditional equipment, the above structure can quickly locate the problem caused by foreign matter jamming by checking the position of the drive rod 42, the contact status of the conductive sheet group, etc. after the accident occurs, which is convenient for maintenance personnel to accurately find the root cause of the fault, shorten the maintenance time, reduce the maintenance cost, and improve the operating stability of the entire coil feeding system.

[0042] If a short circuit occurs in the feeder housing 11 during the process of transporting the coil, the strong current generated by the short circuit will rapidly increase the magnetic force inside the magnetic coil 26, and then the magnetic coil 26 will rapidly pull the striker column 24 down through the internal magnetic force, and the striker column 24 will gradually compress the first return spring 25; The process of rapid descent of the striker column 24 is the same as the above-mentioned movement process. During the descent of the striker column 24, it will collide with the power-off paddle 29 to rotate, and the power-off paddle 29 will paddle the conductive plate 27 and the triangular power transmission plate 23 to gradually separate. When the triangular power transmission plate 23 and the conductive plate 27 stop collide, the device is powered off and the alarm light 35 is automatically extinguished. In the event of a short circuit in the equipment, an arc will be generated during the separation of the conductive plate 27 and the triangular transmission plate 23, and during this process, the arc will flow into the arc extinguishing chamber 210 along the direction of separation of the conductive plate 27 and the triangular transmission plate 23. The arc energy is consumed by the special materials and structures in the arc extinguishing chamber 210 to extinguish the arc, thereby fundamentally eliminating the potential hazards caused by the arc and creating a safer electrical environment for equipment operation. At the same time, compared with the traditional coil feeder safety warning device, the above structure realizes the rapid separation of the conductive plate 27 and the triangular transmission plate 23 in the face of a short circuit, greatly shortening the time from the occurrence of a short circuit to the power cut-off, effectively protecting the core components of the equipment from long-term high current shocks, and reducing the risk of equipment damage. At the same time, while cutting off the source of the short-circuit current, it ensures the relative stability of other circuits that are not related to the short circuit, so that after the fault is eliminated, only this link needs to be restored to quickly restart the feeder, thereby improving production continuity; Finally, the electromagnetic force generated by the magnetic coil 26 drives the striker column 24, and this mechanical action is closely combined with electrical components such as the conductive plate 27 and the triangular transmission plate 23, so as to mechanically drive the electrical cut-off, and the electrical feedback ensures the continuous and stable mechanical action, forming an organic protection whole. It can better cope with complex and changeable short-circuit fault scenarios than a single protection mode, and comprehensively improve the safety of the equipment.

[0043] At the same time, in the event of a short circuit or foreign object jamming in the coil feeder, the equipment can automatically cut off the power and the alarm light 35 will automatically go out. Compared with the traditional coil feeder, the safety warning device has a single function and cannot take into account different types of fault monitoring such as short circuit and foreign object jamming at the same time. The above structure realizes the simultaneous and accurate monitoring of these two faults.
