Description

Technical Field

[0001] This invention relates to the field of automated storage and retrieval system (AS / RS) conveying technology, and more specifically, to a powder scraper conveyor for AS / RS. Background Technology

[0002] Automated storage and retrieval systems (AS / RS) are intelligent warehousing systems that use high-rise racks to store goods, combined with stacker cranes, supporting conveying equipment, and warehouse management and control systems to automatically complete the storage, retrieval, and transfer of goods. They can make full use of the vertical space of the warehouse to realize the automated inbound, storage, and outbound of materials, and are the core warehousing equipment in the modern intelligent logistics system.

[0003] When scraper conveyors are used in conjunction with automated storage and retrieval systems (AS / RS) to transport powder materials, the frictional resistance between the scraper and the inner wall of the conveyor box increases when the powder material is highly viscous or when the conveyor chain becomes loose after long-term operation. To maintain continuous material transport, the drive motor needs to increase its output torque to overcome the additional operating resistance, resulting in continuous high torque load. If the resistance continues to rise, the output torque of the drive motor will exceed its rated load range. Long-term overload operation can easily lead to overheating of the drive motor, damage to the windings, and even damage to the entire machine. This not only causes component failure and shutdown but also interrupts the continuous transport of powder materials to the AS / RS, affecting the stable operation of the warehousing and receiving process.

[0004] Based on this, the present invention discloses a powder scraper conveyor for automated three-dimensional warehouses. Summary of the Invention

[0005] To address the problem mentioned in the background art where excessive output torque of the drive motor affects its service life, this invention provides a scraper conveyor for powder in an automated storage and retrieval system. The conveyor includes a conveyor box and a scraper conveying structure disposed inside the conveyor box. The scraper conveying structure includes two conveying rollers symmetrically rotated and mounted on the inner wall of the conveyor box. Conveyor chains are fitted onto both ends of the two conveying rollers. A plurality of evenly distributed conveying scrapers are disposed between the two conveyor chains. A drive motor is fixedly mounted at one end of the bottom surface of the conveyor box, and a torque sensor is fixedly mounted on the bottom surface of the conveyor box. The device is connected to the output end of the drive motor. One end of a conveying roller located above the drive motor passes through the side of the conveying box. A fixed frame is fixedly installed on the side of the conveying box. A shaft is rotatably installed on the end of the fixed frame away from the conveying box. A transmission sprocket is fixedly installed on one end of the shaft and one end of the torque sensor. A transmission chain is fitted on the two transmission sprockets. A transmission assembly is provided between the shaft and the conveying roller to transmit the output power of the drive motor to the conveying roller. A disconnection assembly is provided on the fixed frame to cut off the power connection between the shaft and the conveying roller when the output torque of the drive motor is too large.

[0006] As a further improvement to this technical solution, the shaft and the conveying roller are coaxially arranged, and the open end of the conveying box is provided with several cover plates.

[0007] As a further improvement to this technical solution, the transmission assembly includes a transmission disc fixedly installed on one end of the conveying roller located outside the conveying box, a drive disc slidably fitted on the outer wall of the shaft, two transmission teeth symmetrically fixedly installed on the opposite ends of the transmission disc and the drive disc, two guide openings symmetrically opened at the fitting point between the drive disc and the shaft, and two guide strips slidably connected to the guide openings fixedly installed on the outer wall of the shaft.

[0008] As a further improvement to this technical solution, a limiting plate is fixedly installed at the end of the shaft away from the transmission sprocket.

[0009] As a further improvement to this technical solution, the disconnection assembly includes a connecting plate fixedly installed on the side of the fixed frame. A rotating shaft is rotatably installed on the bottom surface of the connecting plate. A rotating plate is fixedly fitted on the outer wall of the rotating shaft. A connecting frame is fixedly installed at the end of the rotating plate. An installation ring is rotatably fitted on the outer wall of the drive disk. Two sliding grooves are symmetrically opened on the inner wall of the connecting frame. A slider is slidably installed on the inner wall of the sliding groove. Two support rods are symmetrically fixedly installed on the outer wall of the installation ring, and one end of the support rod is rotatably connected to the slider. An electric push rod is hinged to the side of the conveyor box. The telescopic end of the electric push rod is hinged to the side of the rotating plate.

[0010] As a further improvement to this technical solution, the connecting frame is configured as a U-shape, and a controller is provided between the torque sensor and the electric push rod, with the torque sensor and the electric push rod respectively electrically connected to the controller.

[0011] As a further improvement to this technical solution, the fixing frame is equipped with a warning component to warn workers that the drive disc and transmission disc are separated.

[0012] As a further improvement to this technical solution, the warning component includes an audible and visual alarm fixedly installed on the top surface of the mounting frame. The bottom surface of the mounting frame has an installation opening, and the installation opening is vertically aligned with the contact switch of the audible and visual alarm. A trigger rod is slidably installed on the inner wall of the installation opening, and a fixing ring is fixedly fitted on the outer wall of the trigger rod. A spring is fixedly installed between the fixing ring and the opposite side of the mounting frame. A top block for actuating the trigger rod is fixedly installed on the top surface of the connecting frame.

[0013] As a further improvement to this technical solution, the bottom end of the trigger rod and the top end of the top block are both set as hemispherical.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this automated three-dimensional warehouse powder scraper conveyor, the torque sensor accurately collects the output torque data of the drive motor in real time. Once the torque exceeds the limit, the controller can quickly trigger the electric push rod to retract, causing the drive plate and transmission plate to disengage and break the force, instantly cutting off the power connection between the motor and the conveying mechanism. This avoids the problem of burnout and damage caused by continuous high-load operation of the motor, effectively protects the core drive components, reduces the probability of equipment failure and the cost of replacing parts, and extends the service life of the drive motor and the entire conveying equipment.

[0015] 2. In this type of powder scraper conveyor for automated storage and retrieval systems, when abnormal operating conditions such as blockage or sudden increase in friction occur, the power can be quickly disengaged and pressure released to prevent the equipment from being forced to operate with obstructions, which would cause wear, deformation, and jamming of conveying components such as scrapers, conveyor chains, and conveyor rollers. This eliminates problems such as equipment jamming and shutdown, and material accumulation and blockage, effectively ensuring the stability and smoothness of powder conveying operations and maintaining the continuous and efficient operation of the material receiving process in the automated storage and retrieval system.

[0016] 3. In this type of powder scraper conveyor for automated three-dimensional warehouse, the overload disconnection protection action can be activated simultaneously by pushing the trigger rod through the top block of the connecting frame, which can accurately trigger the sound and light alarm to emit a clear sound and light warning signal. This can proactively report abnormal equipment faults in the first instance, making it easier for staff to quickly detect problems such as overload and material blockage of the conveying equipment, and promptly rush to the site to troubleshoot, clear the blockage, and repair the equipment. This shortens the time for fault detection and handling, reduces equipment downtime, and reduces secondary damage and production losses caused by the expansion of the fault.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides a powder scraper conveyor for an automated storage and retrieval system (AS / RS). See [link to relevant documentation]. Figure 1-8As shown, the system includes a conveyor box 1 and a scraper conveying structure 2 disposed inside the conveyor box 1. The scraper conveying structure 2 includes two conveying rollers 201 symmetrically rotated and mounted on the inner wall of the conveyor box 1. Conveyor chains 202 are respectively fitted to both ends of the two conveyor rollers 201. Several evenly distributed conveying scrapers 203 are disposed between the two conveyor chains 202. A drive motor 3 is fixedly mounted on one end of the bottom surface of the conveyor box 1. A torque sensor 4 is fixedly mounted on the bottom surface of the conveyor box 1 and is connected to the output end of the drive motor 3. One end of a conveyor roller 201 located above the drive motor 3 passes through the side of the conveyor box 1. A fixed frame 5 is fixedly installed on the side of the conveyor box 1. A shaft 6 is rotatably installed on the end of the fixed frame 5 away from the conveyor box 1. The shaft 6 is coaxial with the conveyor roller 201. A transmission sprocket 7 is fixedly installed on one end of the shaft 6 and one end of the torque sensor 4. A transmission chain 8 is fitted on the two transmission sprockets 7. A transmission assembly 9 is provided between the shaft 6 and the conveyor roller 201 to transmit the power output of the drive motor 3 to the conveyor roller 201. A disconnection assembly 10 is provided on the fixed frame 5 to cut off the power connection between the shaft 6 and the conveyor roller 201 when the output torque of the drive motor 3 is too large. Several cover plates 12 are provided at the open end of the conveyor box 1.

[0021] In actual operation, the staff first completes the precise erection and debugging of conveyor box 1 to ensure that the installation position and assembly parameters of conveyor box 1 are compatible with the operation standards and operating conditions of the automated warehouse, laying the foundation for subsequent automated powder conveying operations. When the equipment is in operation and conveying powder, the powdery material enters the conveyor box 1 smoothly through the feed port at the top of the conveyor box 1. Then, the drive motor 3 is started. After the drive motor 3 outputs power, it can form a complete power transmission structure through the matching transmission sprocket 7, transmission chain 8 and transmission components 9, which synchronously drives the conveyor roller 201 to rotate at a uniform speed. This, in turn, drives the conveyor chain 202 and the conveyor scraper 203 assembled inside the conveyor box 1 to rotate synchronously. Through the pushing action of the conveyor scraper 203, the powder inside the conveyor box 1 is continuously moved, completing the automated powder conveying operation. Finally, the powder is stably discharged through the discharge port at the bottom of the conveyor box 1 and smoothly sent into the automated warehouse, realizing the powder inbound conveying process. Throughout the normal conveying operation of the equipment, the torque sensor 4 continuously monitors the output torque value of the drive motor 3 in real time. The torque sensor 4 is model YL-10A-100N・m. When the conveying operation is affected by sudden conditions such as excessive viscosity of the powder, powder agglomeration, or material accumulation, which cause material blockage inside the conveying box 1 or loosening of the conveying chain 202, the frictional resistance between the conveying scraper 203 and the inner wall of the conveying box 1 will increase, and the operating load of the equipment will increase accordingly. At this time, the drive motor 3 needs to output greater torque to overcome the operating resistance and maintain the normal conveying operation of the equipment. When the output torque value of the drive motor 3 exceeds the preset value of the torque sensor 4, When the safety threshold is reached, the torque sensor 4 can promptly capture abnormal data and feed it back to the equipment controller, model YL-MC10. The controller quickly triggers the disconnection component 10 to start working. The disconnection component 10 precisely cuts off the power transmission connection between the central shaft 6 of the transmission component 9 and the conveyor roller 201, so that the drive motor 3 is completely disconnected from the subsequent conveying execution structure. This effectively avoids problems such as burnout or damage to the drive motor 3 due to long-term high load or overload operation, ensuring the operational safety of the drive motor 3 and the entire conveying equipment, and realizing the automatic protection function in the event of equipment failure. At the same time, the equipment controller cuts off the power supply to the drive motor 3, and the staff needs to manually restart it after troubleshooting.

[0022] For details, see Figure 5-7 As shown, the transmission assembly 9 includes a transmission disc 901 fixedly installed on one end of the conveyor roller 201 located outside the conveyor box 1, a drive disc 902 slidably fitted on the outer wall of the shaft 6, two transmission teeth 903 symmetrically fixedly installed on the opposite ends of the transmission disc 901 and the drive disc 902, two guide openings 904 symmetrically opened at the fitting point between the drive disc 902 and the shaft 6, two guide strips 905 slidably connected to the guide openings 904 fixedly installed on the outer wall of the shaft 6, and a limit plate 906 fixedly installed on the end of the shaft 6 away from the transmission sprocket 7.

[0023] During routine powder conveying operations in automated warehouses, the disconnection assembly 10 maintains the transmission disc 901 and drive disc 902 in a close-fitting assembly state. After starting the drive motor 3, the power is transmitted to the shaft 6 via the torque sensor 4, transmission sprocket 7, and transmission chain 8, causing the shaft 6 and drive disc 902 to rotate synchronously. The meshing transmission teeth 903 can transmit the rotational power to the transmission disc 901 via the drive disc 902, thereby driving the conveying roller 201 to operate continuously, thus completing the power transmission and powder conveying operation of the entire mechanism. When material blockage occurs inside the conveying channel, and the operating friction resistance increases, causing the output torque of the drive motor 3 to exceed the safety limit, the torque sensor 4 collects the abnormal torque signal in real time and links the disconnection component 10 to perform an action. The disconnection component 10 controls the drive disc 902 to slide away from the transmission disc 901 along the shaft 6 with the guidance and limiting effect of the guide port 904 and the guide bar 905. This causes the transmission teeth 903 that are meshing between the drive disc 902 and the transmission disc 901 to completely disengage, cutting off the power transmitted from the drive motor 3 to the conveying roller 201. The load resistance is no longer transmitted to the drive motor 3, thereby realizing automatic overload tripping and preventing the drive motor 3 from being damaged by long-term exposure to excessive loads, thus fully exerting the overload protection effect on the drive motor 3.

[0024] Further, see Figure 4-8 As shown, the disconnection assembly 10 includes a connecting plate 1001 fixedly installed on the side of the fixed frame 5. A rotating shaft 1002 is rotatably mounted on the bottom surface of the connecting plate 1001. A rotating plate 1003 is fixedly fitted onto the outer wall of the rotating shaft 1002. A connecting frame 1004 is fixedly installed at the end of the rotating plate 1003. The connecting frame 1004 is U-shaped. An installation ring 1005 is rotatably fitted onto the outer wall of the drive disk 902. Two sliding grooves 1006 are symmetrically opened on the inner wall of the connecting frame 1004. A slider 1007 is slidably installed on the inner wall of the 6. Two support rods 1008 are symmetrically fixed on the outer wall of the mounting ring 1005, and one end of the support rod 1008 is rotatably connected to the slider 1007. An electric push rod 1009 is hinged to the side of the conveyor box 1. The telescopic end of the electric push rod 1009 is hinged to the side of the rotating plate 1003. A controller is set between the torque sensor 4 and the electric push rod 1009, and the torque sensor 4 and the electric push rod 1009 are electrically connected to the controller respectively.

[0025] During the normal conveying operation of powder inside the conveying box 1, the electric push rod 1009 maintains its extended working state. Under this condition, the drive disk 902 and the transmission disk 901 come close to each other and establish a reliable meshing relationship by relying on the meshing transmission teeth 903, thereby realizing the power connection between the shaft 6 and the conveying roller 201. The rotational torque output by the drive motor 3 can be smoothly transmitted to the conveying roller 201 to ensure continuous conveying of powder. When an abnormal conveying condition causes the output torque of the drive motor 3 to exceed the limit, the torque sensor 4 captures the abnormal torque signal in real time and transmits it to the controller. After receiving the signal, the controller immediately controls the electric push rod 1009 to perform a retraction action. During the retraction process, the electric push rod 1009 will pull the rotating plate 1003 and the connecting frame 1004 to rotate around the rotating shaft 1002. At the same time, it will be limited by the sliding guide pair formed by the slide groove 1006 and the slider 1007, and simultaneously drive the mounting ring 1005 and the drive disk 902 along the path. The shaft 6 slides axially away from the transmission disk 901, eventually causing the drive disk 902 to disengage from the transmission gear 903 on the transmission disk 901, cutting off the power conveyed by the shaft 6 to the conveying roller 201. The load resistance can no longer be transmitted to the drive motor 3, preventing the drive motor 3 from continuously bearing a large torque load, preventing the motor from overload and burning out, and realizing automatic overload protection of the equipment. After the subsequent fault is diagnosed, the staff can control the electric push rod 1009 to extend and drive the drive disk 902 to reconnect with the transmission disk 902 to restore use.

[0026] Among them, see Figure 5 , Figure 7 and Figure 8 As shown, a warning component 11 is provided on the fixed frame 5 to warn the staff that the drive disc 902 and the transmission disc 901 are separated. The warning component 11 includes an audible and visual alarm 1101 fixedly installed on the top surface of the fixed frame 5. The bottom surface of the fixed frame 5 has an installation port 1102, and the installation port 1102 is aligned vertically with the contact switch of the audible and visual alarm 1101. A trigger rod 1103 is slidably installed on the inner wall of the installation port 1102. A fixing ring 1104 is fixedly fitted on the outer wall of the trigger rod 1103. A spring 1105 is fixedly installed between the fixing ring 1104 and the opposite side of the fixed frame 5. A top block 1106 for pushing the trigger rod 1103 is fixedly installed on the top surface of the connecting frame 1004. The bottom end of the trigger rod 1103 and the top end of the top block 1106 are both hemispherical.

[0027] When the drive motor 3 experiences an abnormal condition of excessive output torque, the electric push rod 1009 drives the rotating plate 1003 and the connecting frame 1004 to rotate around the rotating shaft 1002. At the same time, the top block 1106 on the top surface of the connecting frame 1004 moves synchronously with the connecting frame 1004, pushing the trigger rod 1103 upward. This causes the trigger rod 1103 to slide upward along the guide path of the mounting port 1102 until the top of the trigger rod 1103 touches the contact switch of the audible and visual alarm 1101, completing the switch triggering action. Immediately, the audible and visual alarm 1101 is activated, emitting an audible and visual warning signal. This promptly reminds on-site personnel to quickly detect the overload fault of the conveying equipment, go to the equipment location as soon as possible to check for abnormal problems such as blockage and increased resistance, and carry out corresponding disposal work to prevent the fault from continuing to expand and causing more damage to components.
