Description

Technical Field

[0001] This utility model relates to the field of warehousing technology, and more specifically, to a flat warehouse. Background Technology

[0002] A planar silo is a material storage device that uses a planar storage method. It is widely used in agriculture, manufacturing, and construction, primarily for storing granular, powdery, or lumpy materials such as grains, ores, cement, and feed. Its structure typically consists of storage areas, feeding and discharging devices, and a control system. The storage area is usually an open or semi-open planar space, divided by walls, fences, or partitions. The size of the area can be flexibly adjusted according to the type of material and the storage volume. Common feeding and discharging devices include conveyor belts, screw conveyors, and forklifts, enabling automated or mechanized loading and unloading of materials. The control system... It is used to monitor parameters such as material level and feeding / discharging speed to ensure efficient and orderly storage. Compared with three-dimensional silos, flat silos have the advantages of low construction cost, simple maintenance, and suitability for bulk material storage. The working principle of a flat silo is as follows: materials are sent into the designated flat storage area by conveying equipment and spread evenly by gravity or mechanical means. During storage, the material accumulation height is monitored in real time by material level sensors. When discharging, materials are taken from the storage area by equipment such as forklifts and conveyors and transported to the next stage as needed. The control system coordinates the feeding and discharging rhythm to avoid material overflow or supply interruption, thus realizing the orderly storage and turnover of materials.

[0003] The storage and warehousing of sheet metal goods in a flat warehouse is a crucial process in the warehousing operation of sheet metal goods. In actual use, staff typically use forklifts and conveyor systems to transfer sheet metal goods in and out of the warehouse. However, when transferring sheet metal goods using forklifts and conveyor systems, sufficient space needs to be reserved between different sheet metal goods areas, which makes the handling and transfer of sheet metal goods in and out of the warehouse inconvenient and takes up a lot of storage space, affecting the convenience of transferring sheet metal goods in and out of the flat warehouse and the space utilization rate.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] Reference Figures 1-7This utility model provides a technical solution: a planar warehouse, including a column 1 and a material transfer assembly. A guide beam 2 is fixedly connected to the top of the column 1, and an inclined column 3 is fixedly connected to the top of the side of the column 1. Pads 4 are fixedly connected to the bottom of both the column 1 and the inclined column 3. A crossbeam 5 is movably connected to the top of the guide beam 2. It can perform adsorption-type gripping of external board materials and move and transfer the gripped board materials. It can transfer board materials of the same type to the corresponding storage location, avoiding the need to reserve transfer space in the storage area during the storage of board materials, which would lead to wasted space in the planar warehouse and inconvenience in transferring board materials in and out of the warehouse. Therefore, it improves the convenience of transferring board materials in and out of the warehouse and the space utilization rate.

[0034] Reference Figures 1-7In a preferred embodiment, the material transfer assembly includes a mobile trolley 6, which is movably connected to the bottom of the inner side of a crossbeam 5. A servo motor 7 is fixedly connected to the rear side of the inner side of the crossbeam 5. Pulleys 8 are movably connected to both sides of the inner side of the crossbeam 5 via pins. The output end of the servo motor 7 is connected to the pulleys 8. A belt 9 located at the top of the mobile trolley 6 is connected to the surface of the pulleys 8. The belt 9 is fixedly connected to the mobile trolley 6 via a clamp. A rotating arm 10 is movably connected to the bottom of the mobile trolley 6 via a bearing. A suction cup frame 11 is movably connected to the bottom of the rotating arm 10 via a bearing. A suction cup 12 is mounted on the bottom of the suction cup frame 11. The crossbeam translation assembly is movably connected to... The crossbeam translation component is located on the outer side of the left side inside the crossbeam 5. It is used to translate the crossbeam 5. The material storage component is movably connected to the left side of the inner side of the column 1. This component supports goods entering and leaving the warehouse. The servo motor 7 and the rotating arm 10 are electrically connected to the external warehouse controller and vision information system via wires. The working status of the rotating arm 10 can be programmed through the warehouse controller. When external sheet metal goods move into the working range of the rotating arm 10, the warehouse controller, in conjunction with the vision information system, sends working commands to the servo motor 7 and the rotating arm 10. At this time, the servo motor 7, through the pulley 8 and belt 9, provides driving force to the moving trolley 6, causing it to move... The trolley 6, in conjunction with the crossbeam 5, moves the rotating arm 10 to the position for gripping and transferring sheet metal goods. This allows the rotating arm 10, along with the suction cup frame 11 and suction cup 12, to grip the sheet metal goods. Since the suction cup frame 11 is equipped with a pressure sensor, it can monitor the suction force of the suction cup frame 11 and suction cup 12 and transmit this information to the warehouse controller in real time to ensure the suction force of the suction cup frame 11 and suction cup 12. After the rotating arm 10, in conjunction with the suction cup frame 11 and suction cup 12, grips the sheet metal goods, the trolley 6, in conjunction with the crossbeam 5, moves the rotating arm 10 to transfer the gripped sheet metal goods in and out of the warehouse. The crossbeam translation assembly includes translation wheels. 13. The translation wheel 13 is movably connected to the outer side of the left side inside the crossbeam 5 via a pivot pin. A reducer 14 is fixedly connected to the left side of the inner side of the crossbeam 5. The reducer 14 is connected to the translation wheel 13 via a transmission connection. A side servo motor 15 is connected to the inner side of the reducer 14 via a transmission connection. A following wheel 16 is movably connected to the outer side of the right side inside the crossbeam 5 via a pivot pin. This can form a medium for translating the crossbeam 5 on both sides of the crossbeam 5, allowing the crossbeam 5 to move horizontally on the top of the guide beam 2. This enables the crossbeam 5 to cooperate with the moving trolley 6 to perform a cross-shaped transfer operation on the rotating arm 10, so that the rotating arm 10 can cooperate with the suction cup frame 11 and the suction cup 12 to flexibly grab and transfer external plates, thus improving the translation effect of the crossbeam 5.

[0035] Reference Figures 2-5In a preferred embodiment, by fixing external supports 17 to both the outer and inner sides of the crossbeam 5, and by movably connecting the bottom of the external supports 17 to the outer support rollers 18 that contact the guide beam 2 via a pivot pin, a rolling clamping medium can be formed between the outer side of the crossbeam 5 and the guide beam 2, thus performing translational guidance and reinforcement work between the crossbeam 5 and the guide beam 2, preventing the crossbeam 5 from shifting its position during operation. Therefore, the guiding effect and stability of the translational work of the crossbeam 5 are improved. A support frame 19 is fixedly connected to the rear side of the guide beam 2, and the interior of the support frame 19 is designed with... A cable chain 20 is provided, with one end of the cable chain 20 fixedly connected to the inner wall of the support frame 19 and the other end of the cable chain 20 fixedly connected to the right side of the crossbeam 5. This cable chain 20 can accommodate the wiring of the externally connected servo motor 7, rotating arm 10, and side servo motor 15, making the wiring clear and meeting the requirements of warehouse space utilization and maintenance convenience. It also prevents the wiring from being scattered or tangled, which could lead to damage to the external wiring of the servo motor 7, rotating arm 10, and side servo motor 15. Therefore, it improves the management and protection effect of the external wiring of the servo motor 7, rotating arm 10, and side servo motor 15.

[0036] Reference Figures 2-7 In a preferred embodiment, the material storage unit includes a storage rack 21, which is movably connected to the left side of the inner side of the column 1. An inner support beam 22 is movably connected to the inner side of the storage rack 21. Two retaining columns 23 are movably connected to both sides of the left side of the storage rack 21. Fixed seats 24 are fixedly connected to the bottom of the storage rack 21, the inner support beam 22, and the retaining columns 23 on both sides. This provides pre-entry / exit space for external sheet metal goods and supports and stabilizes the sheet metal goods, allowing the rotating arm 10 to cooperate with the suction cup frame 11 and suction cup 12 to handle the sheet metal goods. To facilitate inbound and outbound operations, and to avoid situations where pre-processing of board materials is difficult, the pre-management effect of board materials entering and leaving the warehouse is improved. A label frame 25 is fixedly connected to the top of the storage rack 21, and a label 26 is fixedly connected to the left side of the label frame 25. This allows for labeling of the storage rack 21, so that staff can clearly label the storage rack 21 according to the actual pre-entry and outbound situation of the board materials. This avoids situations where staff have difficulty identifying the corresponding position of the storage rack 21, thus improving the clarity and convenience of distinguishing the storage rack 21.

[0037] Reference Figures 2-4In a preferred embodiment, guide frames 27 are fixedly connected to the four corners of the moving trolley 6. The top and outer sides of the guide frames 27 are movably connected to guide wheels 28 that contact the inner side of the crossbeam 5 via axle pins. This provides rolling support and guidance between the moving trolley 6 and the crossbeam 5, allowing the belt 9 to smoothly drive the moving trolley 6 to move within the crossbeam 5. This avoids positional deviation of the moving trolley 6 or excessive working resistance between it and the crossbeam 5, thus improving the working connection guidance effect and smoothness between the moving trolley 6 and the crossbeam 5. Limiting frames 29 are fixedly connected to both sides of the top of the guide beam 2, and limiting posts 30 are fixedly connected to the inner side of the limiting frames 29. When the crossbeam 5 moves to its limit position at the top of the guide beam 2, it provides limit isolation and restriction between the crossbeam 5 and the guide beam 2, and buffers the crossbeam 5 after it has moved to its limit position, preventing the crossbeam 5 from moving excessively and detaching from the guide beam 2. This improves the working stability of the crossbeam 5.

[0038] Reference Figures 2-5 In a preferred embodiment, a stabilizing seat 31 located behind the limiting frame 29 is fixedly connected to the rear side of the top of the guide beam 2. A stabilizing frame 32 is fixedly connected to the top of the stabilizing seat 31. Since the stabilizing frame 32 is located at the top of the translational position of the outer support 17, when the outer support 17 moves to the limit position with the crossbeam 5, the stabilizing frame 32 is located at the top of the outer support 17. It can cooperate with the limiting frame 29 to perform external contact isolation between the crossbeam 5 and the guide beam 2 after it has moved to the limit position, thus avoiding the situation where the outer side of the crossbeam 5 is difficult to support and block when it is working. Therefore, the isolation and restriction of the limiting frame 29 is improved. A reinforcing beam 33 is fixedly connected to the top of the crossbeam 5. Lifting rings 34 located outside the reinforcing beam 33 are fixedly connected to both sides of the top of the crossbeam 5. This can perform connection and reinforcement work on the crossbeam 5 and provide the user with a lifting medium for lifting the crossbeam 5, thus avoiding the situation where the crossbeam 5 is not strong enough when it is working. Therefore, the overall strength of the crossbeam 5 is improved.

[0039] Specifically, the working process or principle of this planar warehouse is as follows: During use, servo motor 7, rotating arm 10, and side servo motor 15 are connected to the external warehouse controller and visual information system via wires. The connecting wires are positioned inside the cable chain 20. The cable chain 20, in conjunction with the support frame 19, accommodates, manages, and protects the connecting wires, ensuring stability during connection. After connection to the external warehouse controller and visual information system, servo motor 7, rotating arm 10, and side servo motor 15 are in a low-energy standby state, preparing for subsequent execution of warehouse controller commands. When the external board material is moved to the top of the storage rack 21, the storage rack 21, in conjunction with the inner support beam 22 and the stop column 23, pre-emptively places the board material. During the stable operation of the storage and support system, the warehouse controller, in conjunction with the warehouse visual information system, clearly identifies the location information of the goods on the top inner side of the storage rack 21. Simultaneously, the identification frame 25, along with the identification sign 26, marks the location of different storage racks 21. At this point, the warehouse controller, in conjunction with the warehouse visual information system, sends work commands to the servo motor 7, the side servo motor 15, and the rotating arm 10. Upon receiving the work command, the servo motor 7 drives the pulley 8 to rotate the belt 9 via the equipped reducer. The belt 9 moves the trolley 6 inside the crossbeam 5, causing the trolley 6 to move the rotating arm 10. Upon receiving the work command, the side servo motor 15 drives the translation wheel 13 to rotate via the reducer 14, causing the translation wheel 13 to apply a translational force to the crossbeam 5. The horizontal beam 5 is moved horizontally, causing it to move in a cross shape with the trolley 6, allowing the trolley 10 to move flexibly to the top of the corresponding plate material. During this process, the outer support 17 drives the outer support wheel 18 to follow the horizontal beam 5, clamping and guiding the horizontal beam 5 and the guide rail beam 2. The limiting frame 29, in conjunction with the rubber limiting post 30, and through the stabilizing seat 31 and the stabilizing frame 32, provides contact buffering and restriction between the horizontal beam 5 and the guide rail beam 2 after it has moved to its limit position, ensuring the stability of the horizontal beam 5 during its horizontal movement. At this time, the guide frame 27 drives the guide wheel 28 to roll along the trolley 6 inside the horizontal beam 5, providing rolling support and guidance between the trolley 6 and the horizontal beam 5, reducing the risk of damage to the trolley. The working friction between the 6 and the crossbeam 5 increases the smoothness of the operation of the moving trolley 6. Simultaneously, the reinforcing beam 33 connects and reinforces the crossbeam 5, ensuring its overall strength during operation. When the crossbeam 5 moves in conjunction with the moving trolley 6 to move the rotating arm 10 to the top of the board material inside the storage rack 21, the warehouse controller, in conjunction with the warehouse vision information system, monitors and controls the real-time position of the rotating arm 10 and sends working instructions to it. Upon receiving the instructions, the rotating arm 10, according to the working pattern programmed by the staff through the warehouse controller, drives the suction cup frame 11 to move towards the board material, causing the suction cup 12 to contact and adhere to the material for gripping. At this time, the pressure sensor equipped on the suction cup frame 11...The pressure intensity of the suction cup frame 11 and suction cup 12 in adsorbing and grasping the sheet metal goods is monitored, and the pressure value is transmitted to the warehouse controller in real time to ensure the pressure intensity of the suction cup frame 11 and suction cup 12 in adsorbing and grasping the sheet metal goods. After the rotating arm 10, together with the suction cup frame 11 and suction cup 12, adsorbs and grasps the sheet metal goods, the warehouse controller, in conjunction with the warehouse vision information system, sends working commands to the side servo motor 15, servo motor 7, and rotating arm 10 again, so that the side servo motor 15, together with the servo motor 7, drives the crossbeam 5 and the moving trolley 6 to move and grasp the sheet metal. The rotating arm 10, positioned behind the sheet metal goods, moves the goods to the corresponding storage location for inbound handling and transfer. When the goods are being moved out of the warehouse, the warehouse controller, in conjunction with the warehouse vision information system, sends work commands to the servo motor 7, side servo motor 15, and rotating arm 10. This causes the rotating arm 10, along with the suction cup frame 11 and suction cup 12, to grip and rotate the sheet metal goods at the corresponding storage location, moving them to the inside of an empty storage rack 21, thus completing the outbound handling and transfer of the sheet metal goods.

[0040] It should be noted that the servo motor 7, the rotating arm 10, the suction cup frame 11, the suction cup 12, the reducer 14, and the side servo motor 15 are all existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition, and principle are clear to those skilled in the art, so they will not be described in detail.
