Description

Technical Field

[0001] This utility model relates to the field of protective equipment technology, and more specifically, to a roller shutter door device. Background Technology

[0002] Loading stations in FMS (Flexible Manufacturing Systems) are typically equipped with roller shutters or guardrails to ensure the safety of operators and equipment. However, existing protective roller shutter structures have the following problems.

[0003] First, existing roller shutter doors consist of components such as motors, rollers, and guide rails. This structure is not only cumbersome to install but also costly, making it unsuitable for widespread deployment in large-scale FMS systems.

[0004] Secondly, the existing roller shutter door transmission method is easily affected by the external environment, such as dust and vibration, which can cause the chain to loosen and derail, resulting in poor transmission stability and requiring frequent maintenance and adjustment, thus affecting the continuity and efficiency of FMS operation.

[0005] Furthermore, in the existing technology, roller shutters and protective devices often lack effective means of personnel safety detection. In particular, during the opening or closing of roller shutters, it is difficult to monitor in real time whether personnel or obstacles suddenly enter the work area, thus causing safety hazards. In addition, there is a lack of effective monitoring of whether there are materials in the workbench. That is, before the equipment is started, it is impossible to determine whether the roller shutter should be controlled to move based on the monitoring results.

[0006] In addition, existing technologies often lack a precise detection and feedback mechanism for the lifting and lowering position of the door. When the roller shutter door is opened or closed, it is impossible to accurately determine whether it has fully moved into position, making it difficult to promptly remind the operator of the real-time status of the door.

[0047] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] like Figures 1 to 9 As shown, the roller shutter door device of this application includes: a roller shutter door assembly 10 and a protective plate assembly 20. The protective plate assembly 20 includes two first protective plates 201 spaced apart and located on the same side of the roller shutter door assembly 10, which together with the roller shutter door assembly 10 form a placement space 310 for placing a workbench 30 and an opening 320 located on the side of the placement space 310 away from the roller shutter door assembly 10; a first monitoring component 40 is disposed on the first protective plate 201 and facing the workbench 30 to monitor whether there is material on the workbench 30, and to determine whether to control the movement of the roller shutter door assembly 10 based on the monitoring results; a second monitoring component 100 is disposed on the protective plate assembly 20 and facing at least one of the opening 320 and the placement space 310 to monitor the position of the worker, and to determine whether to control the start and stop of the workbench 30 and whether to issue an alarm based on the monitoring results.

[0049] As can be seen, the roller shutter door device of this utility model, by integrating the roller shutter door assembly 10 and the protective plate assembly 20, achieves effective isolation and protection of the loading and unloading station working area of ​​the FMS flexible manufacturing system. The placement space 310 formed by the two first protective plates 201 and the roller shutter door assembly 10 ensures that the working environment around the workbench 30 is safe and controllable. The first monitoring component 40 can detect whether there is material on the workbench in real time, ensuring that the roller shutter door will only move under safe conditions, reducing potential dangers caused by unknown material status. The second monitoring component 100 further enhances safety by monitoring the activities of personnel in the opening 320 and the placement space 310. It can control the start and stop of the workbench in time when someone enters the danger zone and issue a warning signal, thereby effectively protecting personnel from injury and effectively solving the problem of safety hazards of roller shutter doors in the prior art.

[0050] like Figure 2 As shown, a plurality of parallel connecting beams 2011 are provided between the two first protective plates 201. The plurality of connecting beams 2011 are located within the placement space 310, and both ends of each connecting beam 2011 are respectively connected to the two first protective plates 201; and / or, the first protective plate 201 includes a main body 2012 and a plurality of reinforcing plates 2013. At least a portion of the plurality of reinforcing plates 2013 are sequentially connected along the periphery of the main body 2012 and are all connected to the main body 2012. The plurality of reinforcing plates 2013 are all located on the side of the main body 2012 closest to the placement space 310; and / or, the first protective plate 201 is provided with a communication port. The protective plate assembly 20 includes a protective net 2014 provided at the communication port. The protective net 2014 is integrally formed with the first protective plate 201 or detachably connected to it.

[0051] This application significantly improves the overall structural stability of the protective plate assembly 20 by setting multiple connecting beams 2011 in parallel between the two first protective plates 201, effectively preventing deformation or damage to the protective plates caused by external impact or long-term use, and ensuring the long-term reliability and safety of the protective device. The combination of the main body 2012 and multiple reinforcing plates 2013 not only increases the strength and rigidity of the protective plate, but also forms a more enclosed protective structure by placing the reinforcing plates 2013 on the side closer to the placement space 310, further reducing the potential injury to operators in the event of material splashing or equipment failure.

[0052] Preferably, the communication port provided on the first protective plate 201, in conjunction with the detachable protective net 2014, allows operators to conveniently inspect and maintain the equipment below or inside the workbench 30, improving maintenance efficiency and reducing maintenance costs. The one-piece molding or detachable connection design of the protective net 2014 allows the device to adapt to the specific needs of different workbenches and loading stations, and the protective net can be quickly adjusted or replaced according to the actual situation, enhancing the adaptability and ease of assembly of the protective device.

[0053] like Figure 5 , Figure 7 and Figure 8 As shown, the roller shutter door device also includes a third monitoring component 50, which includes: a sensor connector 510 fixed on the roller shutter door assembly 10; and a micro-motion sensor 520 disposed on the first protective plate 201 and located on the side of the first protective plate 201 closer to the roller shutter door assembly 10, so that when the roller shutter door assembly 10 is opened to a predetermined position, the sensing probe of the micro-motion sensor 520 contacts the sensor connector 510 to remind the roller shutter door assembly 10 to move into position.

[0054] The third monitoring component 50 of this application, through the cooperation of the micro-motion sensor 520 and the sensor connector 510, can accurately detect whether the roller shutter door assembly 10 has moved into place, thereby avoiding safety accidents caused by the uncertain position of the roller shutter door and ensuring the safety of operators during equipment startup or operation; and the linkage between the micro-motion sensor 520 and the FMS flexible manufacturing system realizes the automatic monitoring and feedback of the movement status of the roller shutter door assembly 10, eliminating the need for manual inspection of the position of the roller shutter door, and greatly improving the automation level and operating efficiency of the equipment.

[0055] Preferably, the introduction of the monitoring component in this application can promptly detect abnormal states of the roller shutter assembly 10, such as not being fully open or closed, preventing the equipment from operating under abnormal conditions, thereby reducing equipment downtime caused by roller shutter malfunctions and lowering maintenance costs.

[0056] Specifically, the roller shutter door device further includes a snap-fit ​​assembly 60, which includes a first snap-fit ​​part 610 and a second snap-fit ​​part 620 that snap together. The first snap-fit ​​part 610 is disposed on the first protective plate 201, and the second snap-fit ​​part 620 is disposed on the roller shutter door assembly 10. The snap-fit ​​assembly 60 also includes a mounting frame 630, which includes a first plate 631, a second plate 632, a third plate 633, and a fourth plate 634 connected in sequence. The first plate 631 and the second plate 632 are arranged at a predetermined angle, and the second plate 632 and the third plate 633 are arranged at a predetermined angle. The first plate 631 and the fourth plate 634 are parallel to each other, and the third plate 633 and the fourth plate 634 are perpendicular to each other. The first plate 631 is connected to the first protective plate 201, and the first snap-fit ​​part 610 is disposed on the third plate 633. The micro-motion sensor 520 is connected to the fourth plate 634.

[0057] The design of the snap-fit ​​assembly 60, especially the complex geometry of the first plate 631 to the fourth plate 634 in the mounting bracket 630, significantly enhances the overall structural stability of the roller shutter device. This stability ensures that the connection between the first protective plate 201 and the roller shutter assembly 10 remains reliable even during frequent opening and closing of the roller shutter, avoiding mechanical failures or safety accidents caused by loose components.

[0058] The engagement of the first engaging part 610 and the second engaging part 620 ensures precise engagement of the roller shutter door assembly 10 at a specific position, which helps improve the positioning accuracy of the roller shutter door, avoids shaking or misalignment of the roller shutter door during opening and closing, and ensures the smooth operation and precise positioning of the roller shutter door assembly.

[0059] The use of the snap-fit ​​component 60 in this application, especially the integrated mounting bracket 630 design, simplifies the installation process of the roller shutter door device and also facilitates subsequent maintenance and adjustment. This modular design concept greatly reduces the time and difficulty of on-site assembly, and also facilitates disassembly and reassembly when the roller shutter door needs maintenance or replacement.

[0060] like Figure 2 As shown, the roller shutter door device also includes: a drive assembly 70, the fixed end of which is connected to the protective plate assembly 20; and a transmission assembly 80, the output end of which is connected to the transmission assembly 80. At least a portion of the transmission assembly 80 is disposed within the placement space 310 and is connected to the free end of the roller shutter door assembly 10. The drive assembly 70 drives the free end of the roller shutter door assembly 10 to move along a predetermined motion trajectory via the transmission assembly 80.

[0061] The combined use of the drive assembly 70 and the transmission assembly 80 ensures that the roller shutter assembly 10 can run smoothly along the preset motion trajectory. The drive assembly provides a stable power source, while the transmission assembly accurately transmits the power to the roller shutter, avoiding the power loss and instability that may be caused by direct drive, making the opening and closing action of the roller shutter more precise and reliable.

[0062] Since part of the transmission component 80 is located within the storage space rather than being completely exposed, it is protected to some extent from the influence of the external environment, such as dust and oil, thereby extending the service life of the transmission component and reducing maintenance frequency and costs.

[0063] Specifically, the transmission assembly 80 further includes: a first transmission component 810, located on the side of the first protective plate 201 near the roller shutter assembly 10. The first transmission component 810 includes two first bearing assemblies 811 and a first rotating shaft 812. The output end of the drive assembly 70 is connected to the first rotating shaft 812. The two first bearing assemblies 811 are located at both ends of the first rotating shaft 812 and are respectively disposed on the two first protective plates 201. Each first bearing assembly 811 includes a first bearing seat 8111 and a first mounting plate 8112. The first mounting plate 8112 is connected to the corresponding first protective plate 201. The first bearing seat 8111 is disposed on the first mounting plate 8112 and sleeved on the first rotating shaft 812.

[0064] The first transmission component 810 is tightly connected to the drive assembly 70 via the first rotating shaft 812. Two first bearing assemblies 811 are distributed at both ends of the first rotating shaft to provide support. This design ensures high efficiency in power transmission and precision in transmission action. The presence of the bearing assemblies greatly reduces friction and energy loss during movement, making the movement of the roller shutter assembly 10 smoother and more fluid, with a faster response speed.

[0065] The combined use of the first bearing housing 8111 and the first mounting plate 8112 provides a solid support structure for the transmission assembly 80, effectively distributing the load on the first rotating shaft 812, enhancing the mechanical strength and durability of the entire transmission assembly, and reducing the failure rate caused by structural deformation or component loosening.

[0066] By setting the first bearing assembly 811 on the first protective plate 201, the motion mechanism of the roller shutter assembly 10 is effectively protected, reducing the impact of external environmental factors such as dust, humidity and temperature changes on the transmission components, and improving the operational stability and service life of the equipment in harsh environments.

[0067] Specifically, the transmission assembly 80 further includes: a second transmission component 820, located on the side of the first protective plate 201 near the roller shutter assembly 10. The second transmission component 820 is located above the first transmission component 810. The second transmission component 820 includes two second bearing seats 821 and a second rotating shaft 822. The two second bearing seats 821 are located at both ends of the second rotating shaft 822 and are respectively disposed on the two first protective plates 201. Each second bearing seat 821 is sleeved on the outside of the second rotating shaft 822.

[0068] By adding a second transmission component 820, positioned on the same side but above the first protective plate 201, a double-layer transmission structure is formed. This design not only provides an additional transmission path, enhancing the reliability of the roller shutter's opening and closing action, but also ensures that if one layer of the transmission component fails, the other layer can still take over the normal driving task of the roller shutter, avoiding the equipment downtime risk that may be caused by a single transmission path.

[0069] The parallel use of the first transmission component 810 and the second transmission component 820 can better balance the load during the transmission process, making the power distribution more even, reducing excessive stress on individual transmission components, and extending the overall service life of the transmission assembly 80. The addition of the second rotating shaft 822 and the second bearing seat 821, through precise matching and optimization of bearings and shafts, further improves the smoothness and synchronization of the roller shutter assembly during movement, and reduces vibration and deviation during movement. This is extremely important for ensuring the safety and stability of the roller shutter when it is running at high speed.

[0070] like Figure 3 and Figure 4As shown, the transmission assembly 80 further includes: two transmission chain groups 830, each corresponding to one of the two first protective plates 201. Each transmission chain group 830 includes a driving sprocket 831, a driven sprocket 832, a first idler wheel 833, a second idler wheel 834, and a chain 835. The output end of the drive assembly 70 is drivenly connected to one driving sprocket 831. Each driving sprocket 831 is sleeved on a first rotating shaft 812, and each driven sprocket 832 is sleeved on a second rotating shaft 822. Each first idler wheel 833 and second idler wheel 834 are rotatably mounted on their respective first protective plates 201. Each driving sprocket 831 and each driven sprocket 832 is provided with... On the side of the corresponding first protective plate 201 near the roller shutter assembly 10, each first idler wheel 833 is disposed on the side of the first protective plate 201 near the opening 320. Each driven sprocket 832 and each first idler wheel 833 are located on the upper side of the first protective plate 201. Each chain 835 is sleeved on the corresponding driving sprocket 831, the corresponding driven sprocket 832 and the corresponding first idler wheel 833. Each second idler wheel 834 is located below the corresponding driven sprocket 832. Each second idler wheel 834 is disposed on the side of the corresponding driven sprocket 832 near the first idler wheel 833 and on the side of the corresponding chain 835 away from the driven sprocket 832, so as to support the chain 835.

[0071] The introduction of the drive chain assembly 830, through the coordinated work of the driving sprocket 831, driven sprocket 832, first idler sprocket 833, second idler sprocket 834, and chain 835, greatly improves the efficiency and accuracy of power transmission. The cooperative use of the chain and sprockets ensures smooth power transmission from the drive assembly 70 to the roller shutter assembly 10, reducing losses and delays during power transmission.

[0072] The first idler wheel 833 and the second idler wheel 834 not only guide the chain 835, but more importantly, they effectively support the chain, reduce the slack and sway of the chain during movement, thereby improving the operational stability and durability of the entire transmission assembly 80. The reasonable arrangement of the idler wheels ensures that the chain can maintain good operating conditions whether at high speed or low speed.

[0073] In this application, the sprocket and idler wheel of the transmission chain assembly 830 are respectively located on the upper side of the first protective plate 201 and below the driven sprocket. This arrangement makes full use of the vertical space of the equipment, reduces the occupation of the horizontal space, optimizes the layout of the equipment, and enables the roller shutter door device to adapt to more diverse loading station space constraints, thereby improving space utilization efficiency.

[0074] like Figure 2As shown, the transmission assembly 80 also includes a plurality of chain connectors 801, which are sequentially arranged on the chain 835 along the length direction of the chain 835; the roller shutter assembly 10 includes a plurality of door panels 110, which are spaced apart along the length direction of the protective plate assembly 20, and the plurality of door panels 110 are connected to the plurality of chain connectors 801 in a one-to-one correspondence, so as to drive the roller shutter assembly 10 to move when the chain 835 moves.

[0075] Multiple chain connectors 801 are evenly distributed along the length of the chain 835 and are connected one-to-one with multiple door panels 110. This design ensures the uniformity and stability of the roller shutter assembly 10 as it moves under the drive of the chain, reduces door swaying or offset caused by uneven chain force, and improves the smoothness and reliability of the roller shutter opening and closing process.

[0076] This application achieves efficient power distribution and transmission through the connection between the chain connector 801 and the door panel 110. Each chain connector can effectively transmit the power of the chain 835 to the corresponding door panel, avoiding loss and waste during power transmission and ensuring the rapid response and high-efficiency operation of the roller shutter door assembly.

[0077] like Figures 2 to 6 As shown, the transmission assembly 80 also includes two tensioning components 840, which are respectively located on the two first protective plates 201. Each tensioning component 840 includes an adjusting block 841 and an adjusting screw 842. The adjusting block 841 is fixed on the corresponding first protective plate 201 and threadedly connected to the adjusting screw 842. The adjusting screw 842 abuts against the corresponding first mounting plate 8112, so that by driving the first mounting plate 8112 to move, the corresponding drive sprocket 831 moves synchronously to tension the corresponding chain 835. The first mounting plate 8112 is provided with a plurality of waist holes 81121, and the first protective plate 201 is provided with a plurality of fastening holes. A plurality of fasteners 200 pass through the plurality of waist holes 81121 one by one and connect to the plurality of fastening holes to fix the first mounting plate 8112 and the first protective plate 201. When it is necessary to tension the chain 835, the first mounting plate 8112 can be moved relative to the first protective plate 201 by loosening the plurality of fasteners 200.

[0078] The tensioning component 840 incorporates an adjusting block 841 and an adjusting screw 842. Through the threaded connection between the adjusting screw and the adjusting block, and the abutment between the adjusting screw and the first mounting plate 8112, fine-tuning of the position of the drive sprocket 831 is achieved, thereby precisely adjusting the tension of the chain 835. This ensures that the chain will not experience a decrease in power transmission efficiency or operational instability due to slack during long-term operation.

[0079] In this application, proper chain tension can significantly reduce the relative slippage between the chain and sprocket, prevent unnecessary chain jumping or detachment from the sprocket, thereby reducing wear, extending the service life of the chain and sprocket, and reducing maintenance costs and equipment downtime.

[0080] Specifically, the waist hole 81121 on the first mounting plate 8112 and the fastening hole on the first protective plate 201 work together. When it is necessary to adjust the chain tension, simply loosen the fastener 200 to easily move the first mounting plate, complete the chain tensioning, and then tighten it again. This design simplifies the maintenance process and reduces the time and labor costs required to adjust the chain tension.

[0081] like Figure 3 As shown, each drive chain assembly 830 further includes: a first chain guide 81, which is disposed on the first protective plate 201 and located between the driving sprocket 831 and the driven sprocket 832. The first chain guide 81 is located on the side of the first protective plate 201 near the roller shutter assembly 10 and extends along the length of the first protective plate 201. The side of the first chain guide 81 near the roller shutter assembly 10 forms a first guide area 82 for the chain 835 to pass through; and a second chain guide 83, which is parallel to and spaced apart from the first chain guide 81. The second chain guide 83 is disposed on the first protective plate 201 and located on the side of the first chain guide 83 near the first chain guide 831. On one side of the idler wheel 833, a second guide area 84 is formed on the side of the second chain guide 83 away from the first chain guide 81 for the chain 835 to pass through; two third chain guides 85 extend along the width direction of the first protective plate 201 and are spaced apart along the length direction of the first protective plate 201. Both third chain guides 85 are disposed on the first protective plate 201 and located between the driven sprocket 832 and the first idler wheel 833. The lower side of the lower third chain guide 85 forms a third guide area 86 for the chain 835 to pass through, and the upper side of the upper third chain guide 85 forms a fourth guide area 87 for the chain 835 to pass through.

[0082] The first chain guide 81 and the second chain guide 83 in this application form a first guide area 82 and a second guide area 84, providing a clear running trajectory for the chain 835, ensuring stable guidance of the chain between the driving sprocket 831 and the driven sprocket 832, reducing the risk of lateral swaying and derailment of the chain during operation, and improving the accuracy and reliability of chain operation.

[0083] Two third chain guides 85 form a third guide zone 86 and a fourth guide zone 87 between the driven sprocket 832 and the first idler sprocket 833, respectively. Through the guiding effect of these guide zones, the tension distribution of the chain in the vertical direction is optimized, the chain is prevented from loosening prematurely under the action of gravity, the chain is ensured to be evenly stressed throughout the entire motion path, and the service life of the chain is extended.

[0084] Preferably, the addition of the guide component in this application reduces the direct contact between the chain and the protective plate, reduces frictional noise during chain operation, and the material and design of the guide component can reduce wear between the chain and the guide component, thereby reducing the damage rate of the chain and the guide component and reducing maintenance costs.

[0085] Specifically, in this application, multiple reinforcing plates 2013 form a protective groove, two transmission chain groups 830 are located outside the protective groove, and the second chain guide 83 and the reinforcing plates 2013 together form a second guide area 84 for the chain 835 to pass through, and the third chain guide 85 located below and the reinforcing plates 2013 together form a fourth guide area 87 for the chain 835 to pass through.

[0086] like Figure 9 As shown, the first idler wheel 833 also includes: an idler wheel 1, two bearings 2, an idler wheel shaft 3, a shaft end retaining ring 4, a washer 5, a spring washer 6, and a screw 7. Each idler wheel 1 rotates around its own rotation axis. The two bearings 2 are rotatably mounted on the idler wheel 1. The idler wheel shaft 3 is inserted into the idler wheel 1 and the two bearings 2. The end of the idler wheel shaft 3 away from the idler wheel 1 is provided with a shaft end retaining ring 4, a washer 5, and a spring washer 6 in sequence. The screw 7 passes through the shaft end retaining ring 4, the washer 5, and the spring washer 6 and is threadedly connected to the idler wheel shaft 3.

[0087] The first idler wheel 833 of this application is constructed with the idler wheel shaft 3, two bearings 2, and the idler wheel 1 working together to ensure high smoothness and stability when the idler wheel rotates around its own axis. The presence of the bearings greatly reduces the frictional resistance when the idler wheel rotates, and even under high load and high speed, it can maintain the smooth rotation of the idler wheel, thereby improving the overall efficiency and stability of the chain drive system.

[0088] Preferably, the use of the shaft end retaining ring 4, washer 5, spring washer 6 and screw 7 provides additional fastening and anti-loosening measures for the connection between the idler shaft 3 and the idler 1 and its bearing 2. Under the action of the retaining ring and spring washer, even in the environment of long-term vibration and thermal expansion and contraction, the firm connection between the parts can be maintained, avoiding inaccurate transmission or even equipment failure due to loosening.

[0091] In this way, the roller shutter door device of this utility model, by integrating the roller shutter door assembly 10 and the protective plate assembly 20, achieves effective isolation and protection of the loading and unloading station working area of ​​the FMS flexible manufacturing system. The placement space 310 formed by the two first protective plates 201 and the roller shutter door assembly 10 ensures that the working environment around the workbench 30 is safe and controllable. The first monitoring component 40 can detect whether there is material on the workbench in real time, ensuring that the roller shutter door will only move under safe conditions, reducing potential dangers caused by unknown material status. The second monitoring component 100 further enhances safety by monitoring the activities of personnel in the opening 320 and the placement space 310. It can control the start and stop of the workbench in time when someone enters the danger zone and issue a warning signal, thereby effectively protecting personnel from injury and effectively solving the problem of safety hazards of roller shutter doors in the prior art.
