Description

Technical Field

[0001] This utility model relates to the field of casting storage management technology, and in particular to a casting storage positioning device. Background Technology

[0002] In the casting manufacturing industry, after cleaning and inspection, castings typically need to be stored in warehouses for subsequent delivery or processing. Traditional casting storage methods have many problems: while simple shelving can achieve layered storage, the retrieval of castings relies entirely on manual labor or forklift operations, which not only suffers from poor positioning accuracy and low efficiency, but also poses serious safety hazards due to the high labor intensity of manual handling for heavy or structurally complex castings. Direct stacking is more likely to cause damage to castings from bumps and knocks, while also resulting in low warehouse space utilization and difficulty in accurately tracking inventory information.

[0003] With the development of intelligent manufacturing and logistics technologies, automated storage and retrieval systems (AS / RS) have been gradually applied to the storage of various goods. However, they are mainly designed for standardized and regularized boxes or pallets. Existing automated storage equipment, such as stacker cranes and shuttle cars, has poor adaptability to castings with irregular shapes, uneven weight distribution, and easily damaged surfaces due to their picking and placing mechanisms (such as mechanical grippers and forks). Directly using general-purpose automated equipment for casting handling can easily lead to casting slippage, surface scratches, or even structural damage due to inaccurate positioning or improper clamping force, failing to meet the special requirements of casting storage.

[0004] Furthermore, existing warehousing systems have significant shortcomings in real-time monitoring of the location status of goods. Traditional methods rely on manual inventory checks or simple photoelectric detection, which cannot accurately and in real-time obtain information on the specific presence, status, and weight of castings at each storage location. This results in untimely updates to inventory data, severely impacting production planning and logistics scheduling efficiency. In particular, when a specific casting needs to be located quickly, existing systems struggle to provide accurate positioning guidance, significantly reducing warehousing operational efficiency. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to provide a casting storage and positioning device that can improve the accuracy and efficiency of casting storage and retrieval, reduce the intensity of manual labor, and reduce the risk of casting damage.

[0006] This utility model is implemented using the following method: A casting storage and positioning device includes a shelf, which consists of multiple layers of storage positions. Each storage position has a pull-out placement slot. A pressure sensor is installed on the bottom surface of the pull-out placement slot. A placement tray for placing castings is pulled out and installed in the pull-out placement slot. Support rods are provided on both the left and right sides of the shelf. A strip-shaped groove is provided on the outer side of the support rod. A first motor is installed in the strip-shaped groove. The output end of the first motor is connected to a screw. A moving block is spirally sleeved on the screw. A U-shaped lifting plate is connected to the outer side of the moving block. A telescopic cylinder is provided between the two vertical plates of the U-shaped lifting plate. A U-shaped support block is provided at the end of the telescopic cylinder. A rotating block is rotatably connected to the U-shaped support block via a rotating shaft. A pull-out plate is connected to the end face of the rotating block. A second motor for driving the rotating shaft is provided on the upper surface of the U-shaped support block. Multiple vacuum suction cups are evenly spaced on the inner side of the pull-out plate.

[0007] Furthermore, a status indicator light is provided on the front of the storage location, the pressure sensor is used to sense whether a casting is placed on the placement tray, and the status indicator light is used to display the current status of the storage location.

[0008] Furthermore, the status indicator light is a tri-color LED light, configured as follows: green light when the storage location is empty, red light when a casting is stored in the storage location, and blue light flashing when a search command is received.

[0009] Furthermore, both the pressure sensor and the status indicator light are electrically connected to the central processing unit.

[0010] The beneficial effects of this utility model are as follows: This utility model achieves precise positioning and retrieval of castings and real-time status monitoring through the coordinated operation of multi-layer storage and automated storage and retrieval mechanisms, combined with pressure sensing and status indication systems. It has the advantages of improving the accuracy and efficiency of casting storage and retrieval positioning, reducing manual labor intensity, and reducing the risk of casting damage.

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Please see Figures 1 to 3As shown, this utility model provides an embodiment: a casting storage and positioning device, including a shelf 1, the shelf 1 consisting of multiple layers of storage positions 2, each storage position 2 having a pull-out placement slot 3, a pressure sensor 31 installed on the bottom surface of the pull-out placement slot 3, and a placement tray 32 for placing castings being pulled out and installed in the pull-out placement slot 3. Support rods 4 are provided on both the left and right sides of the shelf 1, and strip-shaped grooves 41 are provided on the outer side of the support rods 4. A first motor (not shown) is installed in the strip-shaped groove 41, and a screw is connected to the output end of the first motor. 42. A movable block (not shown) is spirally sleeved on the screw 42. A U-shaped lifting plate 5 is connected to the outer side of the movable block. A telescopic cylinder 51 is arranged between the two vertical plates of the U-shaped lifting plate 5. A U-shaped support block 52 is arranged at the end of the telescopic cylinder 51. A rotating block 53 is rotatably connected to the U-shaped support block 52 via a rotating shaft. A pull plate 54 is connected to the end face of the rotating block 53. A second motor 55 for driving the rotating shaft is arranged on the upper surface of the U-shaped support block 52. Multiple vacuum suction cups 56 are arranged at equal intervals on the inner side of the pull plate 55.

[0016] The pull-out placement slot refers to a sliding rail structure on the storage location used to accommodate placement trays. Specifically, it can be implemented using a guide slot with rollers to facilitate the smooth entry and exit of the trays. The pressure sensor is a sensing element embedded in the bottom of the slot, specifically a piezoelectric sensor, used to detect whether the placement tray is carrying a casting. The U-shaped lifting plate is a frame structure with vertical plates on both sides, specifically welded from aluminum alloy profiles, providing installation space for the telescopic cylinder. The vacuum suction cup is a flexible contact component that uses negative pressure to adsorb the casting; specifically, it can be made of silicone material to avoid scratching the casting surface.

[0017] Specifically, when a casting needs to be stored or retrieved, the first motor drives the screw to rotate, causing the moving block to rise and fall along the strip groove, bringing the U-shaped lifting plate to the target storage height. A telescopic cylinder pushes the U-shaped support block forward to the placement tray position, while the second motor drives the rotating shaft to adjust the angle of the pull-out plate, ensuring the vacuum suction cup is in contact with the casting surface. After the pull-out plate secures the casting through vacuum suction, the cylinder retracts, pulling the placement tray out of the storage position, completing the retrieval operation. When the placement tray returns to its original position, a pressure sensor monitors the load-bearing status in real time to ensure positioning accuracy.

[0018] Compared to existing technologies, conventional automated equipment uses rigid grippers or forks, which are ill-suited for handling irregular surfaces of castings. This solution utilizes vacuum suction cups for flexible adsorption, reducing the risk of damage. Traditional shelving lacks status monitoring capabilities; this solution achieves precise positioning and real-time status feedback through the linkage of pressure sensors and the lifting mechanism. Compared to manual handling, this device significantly improves storage and retrieval efficiency and safety through its motor-driven lifting and extension mechanism.

[0019] Through the above technical solutions, this application can realize the automated storage and retrieval of castings, the flexible contact of vacuum suction cups avoids surface damage, the pressure sensor and the lifting mechanism work together to ensure positioning accuracy, the multi-layer shelf structure combined with the adjustable lifting device improves space utilization, and the real-time status monitoring function improves inventory management efficiency.

[0020] Please continue reading. Figure 1 As shown in one embodiment of the present invention, a status indicator light 6 is provided on the front of the storage location 2, the pressure sensor 31 is used to sense whether a casting is placed on the placement tray 32, and the status indicator light 6 is used to display the current status of the storage location.

[0021] The status indicator light is a device installed on the front of the shelf to reflect the usage status of the storage location through different colors or flashing patterns. It can be implemented using LED light groups and connected to the pressure sensor signal via a circuit. The pressure sensor is a sensing element embedded in the bottom of the pull-out placement slot. It can be implemented using a piezoelectric or strain gauge sensor and determines whether the casting has been stored by detecting whether there is a change in weight on the placement tray.

[0022] Specifically, when the placement tray is pushed into the pull-out placement slot, a pressure sensor detects the total weight of the tray and the casting and transmits the signal to the control system. The control system determines whether the storage location is vacant based on a preset threshold, and then drives the status indicator light to switch display modes. For example, when the storage location is unoccupied, the indicator light remains constantly on or off; when a casting is detected being placed, the indicator light switches to another color or brightness. Thus, operators can quickly identify the status of the storage locations visually, without the need for manual inspection or reliance on external database queries.

[0023] Compared to existing technologies, traditional warehousing systems typically rely on manual recording or single photoelectric sensors to determine the occupancy of storage locations, resulting in high detection error rates and delayed information updates. This solution, through the linkage of pressure sensors and indicator lights, achieves real-time physical feedback on the storage location status, avoiding photoelectric detection failures caused by irregular casting shapes, and eliminating data deviations that may arise from manual recording.

[0024] Through the above technical solution, this application solves the problems of manual operation and low detection accuracy in traditional warehousing systems for monitoring the status of storage locations, realizes automated identification and visual indication of the storage and retrieval status of castings, and improves the real-time performance of inventory data and operational efficiency.

[0025] Please continue reading. Figure 1 As shown, in one embodiment of this utility model, the status indicator 6 is a tri-color LED light, configured as follows: green light when the storage location is empty, red light when a casting is stored in the storage location, and blue light when a search command is received.

[0026] Among them, tri-color LED lights refer to semiconductor light source devices capable of emitting red, green, and blue light. Specifically, they can be implemented using integrated packaged three-chip LED modules, with color switching achieved by controlling the current intensity of different color chips. Color configuration refers to establishing a correspondence between different colors and the status of the goods, which can be set through the logic program of the central processing unit. When the pressure sensor detects a change in weight, it triggers a color switching command.

[0027] Specifically, when the pressure sensor detects no load on the placement tray, the central processing unit (CPU) sends a green light signal to the tri-color LED, indicating that the storage location is vacant. When a casting is placed into the pull-out placement slot, causing the pressure sensor to detect a load, the CPU controls the tri-color LED to switch to a solid red state, indicating that the storage location is occupied. When the warehouse management system issues a specific storage location search command, the CPU drives the corresponding storage location's tri-color LED to enter a flashing blue mode, enabling operators to quickly locate the target storage location. The color status changes are completed automatically through a preset program, requiring no manual intervention.

[0028] Compared to existing technologies, traditional warehousing systems often use single-color indicator lights or mechanical signs, which can only indicate whether a storage location is occupied, but cannot distinguish between idle, occupied, and pending statuses. Some systems use audible and visual alarms, but these suffer from high false alarm rates and unclear information delivery. This solution establishes a precise correspondence between storage location status and optical signals through multi-mode display with three-color LEDs, thus solving the problem of the single-mode status indication in traditional warehousing systems.

[0029] Through the above technical solution, this application achieves real-time visual monitoring of the storage location status, allowing operators to accurately identify the current status of the storage location from a distance of ten meters. During casting storage and retrieval operations, the blue flashing mode effectively shortens the storage location positioning time and avoids errors caused by manual verification of storage location numbers. The three-color status indication system and pressure sensors form a closed-loop detection system, ensuring consistency between inventory data and physical storage status.

[0030] Please continue reading. Figure 1 As shown, in one embodiment of this utility model, the pressure sensor 31 and the status indicator light 6 are both electrically connected to the central processing unit.

[0031] Among them, the pressure sensor refers to the device that detects the weight change on the placement plate. Specifically, it can be implemented using piezoelectric or strain gauge sensors, which are used to convert the gravity signal of the casting into an electrical signal and transmit it to the central processing unit.

[0032] The status indicator light is a device that displays the current status of the storage location. Specifically, it can be implemented using a multi-color LED light source module, which is used to intuitively reflect whether the storage location contains castings or is in operation through color changes.

[0033] The central processing unit refers to the controller that receives and processes sensor signals. Specifically, it can be implemented using an embedded microprocessor or a PLC module. It is used to determine the status of the cargo location based on the pressure sensor signals and control the indicator light display mode.

[0034] Specifically, when the placement tray is pushed into the pull-out placement slot, pressure sensors detect changes in the weight the tray bears in real time and transmit the data to the central processing unit (CPU) via wired or wireless communication. The CPU has a built-in logic module that determines if the weight exceeds a preset threshold, indicating that the casting has been stored in the location, and sends a control command to the status indicator light, turning it red. If the weight is below the threshold, the location is considered vacant, and the indicator light turns green. When the warehousing system receives an external search command, the CPU synchronously controls the indicator light of the target location to flash blue, achieving real-time synchronization and visual feedback of status information.

[0035] Compared to existing technologies, traditional warehousing systems rely on manual visual inspection or single photoelectric sensors to determine the status of storage locations, which carries the risk of data update delays and misjudgments. This solution achieves automated detection and accurate judgment of storage location status through the collaborative work of pressure sensors and a central processing unit. Simultaneously, an electrical signal linkage mechanism ensures that status indicator lights strictly correspond to the actual storage conditions of the locations, eliminating errors caused by manual intervention.

[0036] Through the above technical solution, this application realizes real-time monitoring and dynamic feedback of the storage location status during the casting storage process, solves the problems of lagging inventory data updates and inaccurate status display in traditional warehousing systems, and provides a reliable data foundation for automated warehousing management.

[0037] The motor, vacuum suction cup, pressure sensor, and status indicator light in this invention are all existing technologies, which are already clearly understood by those skilled in the art, and will not be described in detail here.

[0038] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
