Description

Technical Field

[0001] This utility model relates to the field of safety protection technology, specifically a safety system for a disassembly device. Background Technology

[0002] Flexible materials like tinplate are soft and easily wrinkled. During processing, they need to be pressed down with rigid materials like steel plates to smooth them, creating an overlapping structure of tinplate and steel plate. Specialized disassembly equipment is required to separate the tinplate from the steel plate. For example... Figure 1 As shown, the board removal equipment is a vacuum suction cup type conveying equipment, which uses suction cups to transport the solder plate, steel plate, and steel plate to their respective conveying production lines. From left to right, the first conveying production line is a trolley for placing the solder plate, the second conveying production line is a roller conveyor for conveying overlapping solder plates and steel plates, and the third production line (omitted in the attached figure) is for placing the steel plate. The suction cup conveying production line in the vacuum suction cup type conveying equipment transports the solder plate and steel plate to the first production line and the third production line, respectively.

[0003] The problem with the existing technology is that there are gaps between the first, second, and third transport production lines, which are also on the working path of the plate-removing equipment. If this area is not effectively protected, workers who accidentally enter the gaps are prone to colliding with the plate-removing equipment, causing serious production safety accidents. Utility Model Content

[0004] This invention provides a safety system for a plate-removing device, which can improve the safe operation performance of existing plate-removing devices.

[0005] This application provides the following technical solution:

[0006] A safety system for a plate dismantling device includes: a moving part for conveying plates, flexible anti-collision parts fixedly arranged around the moving part, a first sensing element arranged between the flexible anti-collision parts and the moving part, which can contact the first sensing element when the flexible anti-collision parts are subjected to external pressure; a second sensor, which is arranged in a neutral position; and a controller for controlling the start and stop of the moving part, wherein the controller is electrically connected to the first sensor and the second sensor respectively.

[0007] Beneficial effects:

[0008] 1. Provides cushioning and immediate stop: Flexible anti-collision components provide cushioning in the event of an accidental collision, reducing direct injury to personnel. When the flexible anti-collision component is subjected to external pressure, it contacts the first sensor, triggering the controller to immediately stop the movement of the moving parts. This immediate response mechanism not only effectively protects the safety of workers but also allows for rapid action to prevent further escalation of the accident.

[0009] 2. A second sensor is installed in the neutral zone to ensure safety: The second sensor can immediately detect if a worker accidentally enters the neutral zone and stop the moving parts via the controller, fundamentally avoiding the potential collision risk. This dual safety mechanism (first sensor and second sensor) ensures that even if one protection system fails, the other system can still function, maximizing the safety of the operator.

[0010] 3. Enhanced Emergency Response Capabilities with Emergency Braking Function: The second sensor can not only automatically detect personnel accidentally entering neutral, but also function as an emergency braking device. In emergencies, workers can actively enter the control range of the second sensor to trigger the equipment to stop operating, thereby quickly interrupting any potentially harmful operations. This function also gives operators more autonomy and a greater sense of security, improving the safety and comfort of the entire work environment.

[0011] In summary, the safety system of this plate-removing equipment provides immediate buffering and stopping functions through the installation of flexible anti-collision components and a first sensor. The inclusion of a second sensor in neutral position enables comprehensive safety monitoring and emergency braking, significantly improving the equipment's safety performance and operational flexibility, ensuring worker safety and production continuity. These improvements work together to make the entire system more reliable and efficient, making it particularly suitable for working environments requiring high safety standards.

[0012] Furthermore, as an improvement, a connecting assembly is provided between the flexible anti-collision component and the moving component. The connecting assembly includes: a connecting plate, which is fixedly connected to the moving component; a mounting strip, which is fixedly connected to the connecting plate, and a stepped mounting groove is provided in the mounting strip; a nut and a lead screw, one end of which is fixedly connected to the flexible anti-collision component, and the other end is inserted into the mounting groove and fixed with a nut. A mounting cavity for mounting a first sensing element is formed between the inner side of the flexible anti-collision component and the mounting strip. The first sensing element is fixedly connected to the mounting strip in the mounting cavity.

[0013] Beneficial effects: The stepped mounting groove within the mounting strip, combined with the design of the nut and lead screw, allows for flexible adjustment and precise fixation of the flexible anti-collision component according to actual needs. This adjustable mechanism ensures that the flexible anti-collision component can closely conform to the moving parts while maintaining sufficient cushioning capacity to adapt to the needs of different sizes and shapes. At the same time, the mounting cavity not only provides installation space for the first sensor but also facilitates the wiring layout between the first sensor and the controller.

[0014] Furthermore, as an improvement, an elevated structure is installed within the gap, and the second sensor is mounted on the elevated structure.

[0015] Beneficial Effects: This design significantly expands the monitoring range of the second sensor. By mounting the sensor on an elevated platform, placing it at a higher position, it can cover the entire unoccupied area more broadly, ensuring that any person or object entering the area can be detected promptly. This improvement not only enhances the effectiveness of security monitoring but also reduces the risk of security incidents caused by blind spots. Simultaneously, this setup reduces the impact of ground obstacles on the sensor, further optimizing monitoring performance.

[0016] Furthermore, as an improvement, multiple mounting holes at different heights are provided on the elevated structure, and the second sensor can be detachably and fixedly connected to the elevated structure in any one of the mounting holes.

[0017] Beneficial effects: The mounting holes allow the second sensor to be fixed at multiple heights on the overhead structure, making the installation and adjustment of the sensor more flexible. The angle and height of the sensor can be adjusted according to actual needs to achieve the best monitoring effect.

[0018] Furthermore, as an improvement, a PLC is selected as the controller.

[0019] Beneficial effects: As a general-purpose industrial automatic control device, PLC has a series of advantages such as high reliability, small size, powerful functions, simple programming, flexibility and versatility, and convenient maintenance.

[0020] Furthermore, as an improvement, a fence is installed in the gap, and the elevated structure is fixedly connected to the fence.

[0021] Beneficial effects: The presence of the fence further reduces the possibility of workers accidentally entering the hazardous area within the gap, providing a physical barrier and effectively isolating operators from operating equipment. The fence not only prevents personnel from entering hazardous areas but also reminds workers of safety boundaries, enhancing their safety awareness. Furthermore, the design of the fence's fixed connection to the elevated structure increases the stability of the component housing the second monitoring element, making it suitable for production sites requiring a high level of safety assurance and significantly improving the overall system's safety and reliability.

[0023] Figure 2 for Figure 1 A schematic diagram of the structure at the location of the central suction cup. Detailed Implementation

[0024] The following detailed description illustrates the specific implementation method:

[0025] The markings in the accompanying drawings include: trolley 1, roller conveyor 2, gap 3, fence 4, suction cup 5, flexible anti-collision component 6, connecting plate 7, mounting strip 8, nut 9, lead screw 10, mounting groove 11, mounting cavity 12, first sensor 13, overhead frame 14, second sensor 15.

[0026] Example 1

[0027] like Figure 1 and Figure 2 As shown, a safety system for a plate-removing device includes a moving part, a controller, and a barrier 4 installed in the gap 3 between the trolley 1 and the roller conveyor 2. In this embodiment, the controller is a PLC.

[0028] A moving component, used for conveying sheet metal, includes a suction cup 5 capable of moving laterally along a guide rail in this embodiment. Driven by a cylinder, the suction cup 5 can also move vertically. Flexible anti-collision components 6 are fixedly arranged around the suction cup 5, and a connecting assembly is provided between the flexible anti-collision components 6 and the suction cup 5 to fix the flexible anti-collision components 6. In this embodiment, the flexible anti-collision components 6 are made of rubber; the connecting assembly includes a connecting plate 7, a mounting strip 8, a nut 9, and a lead screw 10; the connecting plate 7 is screwed to the moving component, and the mounting strip 8 is bolted to the connecting plate 7. A stepped mounting groove 11 is provided in the mounting strip 8, and the cross-section of the mounting groove 11 is a T-shaped structure; the lead screw 10 is as follows... Figure 2 The left end of the screw 10 is bonded and fixed to the flexible anti-collision member 6. The right end of the screw 10 is inserted into the large-diameter end of the mounting groove 11 and fixed with the nut 9. The screw 10 and the nut 9 are threaded together. An mounting cavity 12 is formed between the flexible anti-collision member 6 and the mounting strip 8. A first sensor 13 electrically connected to the controller is set in the mounting cavity 12. The first sensor 13 is a micro switch. The first sensor 13 is fixedly connected to the mounting strip 8 in the mounting cavity 12, so that the flexible anti-collision member 6 can contact the first sensor 13 after being subjected to external pressure. The first sensor 13 responds and sends an electrical signal to the controller to stop the moving part.

[0029] An elevated frame 14 is installed on the fence 4 and fixed to the fence 4 by bolts. An infrared sensor is installed on the elevated frame 14 as a second sensor 15. Multiple internally threaded holes at different heights are made on the elevated frame 14 as mounting holes. The second sensor 15 can be threaded into the elevated frame 14 in any of the mounting holes, thereby achieving a detachable and fixed connection between the second sensor 15 and the elevated frame 14. This allows for arbitrary adjustment of the installation height and sensing range of the second sensor 15.

[0030] The specific implementation process is as follows:

[0031] During the dismantling process where moving parts reciprocate between roller conveyor 2 and trolley 1, the gap 3 is a dangerous area that workers should not enter at will. The second sensor 15 can immediately detect when a worker accidentally enters the gap 3 area and stop the moving parts through the controller. If a worker accidentally enters the gap 3 and a dangerous accident occurs involving a collision between the person and the moving parts, the flexible anti-collision component 6 can provide a certain degree of cushioning upon impact, reducing direct injury to personnel. When the flexible anti-collision component 6 is subjected to external pressure, it will contact the first sensor 13, triggering the controller to immediately stop the movement of the moving parts. This instant response mechanism not only effectively protects the safety of workers but also allows for rapid measures to be taken in the event of an accident to prevent further escalation.
