Description

Technical Field

[0001] This utility model relates to the field of warehousing technology, and in particular to a double-layer storage silo. Background Technology

[0002] In modern industrial production and warehousing, storage silos serve as crucial equipment for the temporary storage and transfer of materials, and their performance directly impacts production efficiency and operating costs. With the advancement of Industry 4.0 and the widespread adoption of intelligent manufacturing, the pace of production is accelerating, leading to more diverse and complex material storage needs. Traditional single-layer storage silos, due to their low space utilization, difficulty in classifying and storing materials, and inability to meet the demands of multi-batch, small-volume production, are gradually becoming bottlenecks restricting the efficient operation of enterprises. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a double-layer storage silo in order to solve the problems existing in the prior art in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a double-layer storage silo, including a profile frame, an upper silo and a lower silo. Materials are placed on the plates of both the upper and lower silos. A guide rail assembly and a cylinder mounting plate are installed on the workbench of the profile frame. A drive assembly is installed on the cylinder mounting plate. The lower silo is located inside the upper silo, forming a stacked sliding mechanism. The drive assembly is connected to both the upper and lower silos respectively, and the upper and lower silos are switched to seamlessly connect and feed materials.

[0005] Furthermore, the upper hopper includes an upper pallet, with side supports installed at both ends of the bottom surface of the upper pallet. A slider connecting plate is installed at the lower end of the side supports. A slider that cooperates with the linear slide rail in the guide rail assembly is installed on the surface of the slider connecting plate. An upper drive plate is installed on the slider connecting plate. The upper drive plate and the slider connecting plate are arranged perpendicularly. The suspended end of the upper drive plate has an upper drive bayonet that cooperates with the drive block on the drive assembly.

[0006] Furthermore, support ribs are installed on both sides of the bottom surface of the upper tray.

[0007] Furthermore, the lower hopper includes a lower pallet, on the bottom surface of which a slider mounting plate and a drive plate are installed. The slider mounting plate is equipped with a slider that cooperates with the linear guide rail in the guide rail assembly, and the drive plate has a lower drive slot that cooperates with the drive block on the drive assembly.

[0008] Furthermore, the drive assembly is divided into an upper drive assembly and a lower drive assembly. The upper drive assembly is connected to the upper hopper, and the lower drive assembly is connected to the lower hopper. The drive assembly includes a rodless cylinder, and a drive block is mounted on the slide of the rodless cylinder.

[0009] Furthermore, the guide rail assembly includes several linear guide rails, with the upper and lower hoppers respectively engaging with the corresponding linear guide rails.

[0010] Furthermore, sensing components are installed on both sides of the profile frame along its length. Each sensing component includes a shaft support, on which an optical axis is mounted. Several fixing clamps are mounted on the shaft of the optical axis, and each fixing clamp is equipped with a through-beam sensor. The two through-beam sensors correspond to the upper hopper and the lower hopper, respectively.

[0011] Furthermore, the perimeter of the profile frame is equipped with a quick-release protective sheet metal, and the two opposite sides of the profile frame are equipped with limit plates, which are fitted with quick-release handles.

[0012] The bottom layer of the profile frame is equipped with solenoid valves and relay boxes.

[0013] The beneficial effects of this utility model are as follows: This utility model is a double-layer cylinder-driven material exchange hopper mechanism. With its unique vertical double-layer design and rapid cylinder response mechanism, it achieves efficient, automated, and seamless material supply. When the material in the upper hopper is depleted, the cylinder can drive the lower hopper to complete the position exchange in a very short time, eliminating the need for the production line to stop waiting for refills. Compared to the frequent shutdowns for refills in traditional single-layer hoppers, this continuous feeding mode effectively reduces equipment idle time, significantly improves production line operating efficiency, and thus greatly increases the company's product output per unit time.

[0014] High-precision guide rails provide stable guidance for the movement of the hopper, strictly controlling the hopper positioning error to an extremely small range. This precise positioning capability ensures that materials are accurately delivered to the processing station every time, making it particularly suitable for precision machining scenarios with stringent positional accuracy requirements. It guarantees product processing quality from the source and reduces the defect rate caused by material feeding deviations.

[0015] The driving force of the cylinder can be flexibly selected according to actual needs. Its strong load adaptability greatly expands the application range of the mechanism and meets the diverse feeding needs of different enterprises and different production scenarios.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] like Figures 1-5 The double-layer storage silo shown includes a profile frame 6, an upper silo, and a lower silo. The profile frame 6 serves as the basic skeleton and supporting structure of the entire storage silo, ensuring the structural strength and stability of the equipment. Materials are placed on the surfaces of both the upper and lower silos. A guide rail assembly and a cylinder mounting plate 11 are installed on the workbench of the profile frame 6. A drive assembly is installed on the cylinder mounting plate 11. The lower silo is located inside the upper silo, forming a stacked sliding mechanism. The drive assembly is connected to both the upper and lower silos, respectively, and can switch between the upper and lower silos to seamlessly connect and feed materials.

[0025] It also includes a control system for setting material parameters and exchanging trigger conditions.

[0026] Among them, such as Figure 2 As shown, the drive component provides power and precisely controls the extension and retraction of the upper and lower hoppers along the linear guide 10, realizing automatic and seamless material feeding between the two layers. The drive component is divided into an upper drive component and a lower drive component, which independently drive the upper and lower hoppers respectively. The upper drive component is connected to the upper hopper, and the lower drive component is connected to the lower hopper.

[0027] like Figure 5As shown, the drive assembly includes a rodless cylinder 12, which is a power source. The internal piston movement drives the external slide to move linearly. Compared with a rod cylinder, it saves air. The slide is the movable part of the rodless cylinder 12, and a drive block 23 is installed on the slide of the rodless cylinder 12.

[0028] The guide rail assembly provides precise, low-friction linear motion guidance for the upper and lower hoppers, ensuring smooth, stable, and accurate movement. The guide rail assembly includes four linear guide rails 10, with each hopper corresponding to a specific linear guide rail 10. Each linear guide rail 10 has a corresponding slider. Figure 2 As shown, the two middle linear guide rails 10 are for the lower hopper, and the two linear guide rails 10 on both sides are for the upper hopper.

[0029] like Figure 3 As shown, the upper hopper includes an upper pallet 26. Side supports 19 are installed at both ends of the bottom surface of the upper pallet 26. The side supports 19 provide vertical support, increase the rigidity of the upper pallet 26, and transfer the load to the slider connecting plate 20. The slider connecting plate 20 is installed at the lower end of the side supports 19. The slider connecting plate 20 is the interface between the upper hopper and the guide rail assembly, allowing the upper hopper to slide along the linear guide rail 10. A slider that cooperates with the linear guide rail 10 in the guide rail assembly is installed on the surface of the slider connecting plate 20. An upper drive plate 21 is installed on the slider connecting plate 20. The upper drive plate 21 and the slider connecting plate 20 are vertically arranged. The suspended end of the upper drive plate 21 has an upper drive bayonet 16 that cooperates with the drive block 23 on the drive assembly. After the rodless cylinder 10 is vented, the slide of the rodless cylinder 10 drives the drive plate 21, thereby causing the top pallet 26 to move laterally along the linear guide rail 10.

[0030] The upper pallet 26 has support ribs 18 installed on both sides of its bottom surface along the length direction to strengthen the structural strength of the bottom of the upper pallet 26 and prevent the upper pallet 26 from bending and deforming under load.

[0031] like Figure 4 As shown, the lower hopper cooperates with the two middle guide rails 10. The lower hopper includes a lower tray 13. A slider mounting plate 14 and a drive plate 15 are installed on the bottom surface of the lower tray 13. The slider mounting plate 14 is installed on the bottom surface of the lower tray 13 and connects to the slider, so that the lower hopper can slide along the linear guide rail. A slider that cooperates with the linear guide rail 10 in the guide rail assembly is installed on the slider mounting plate 14. The drive plate 15 has a lower drive bayonet 17 that cooperates with the drive block 23 on the drive assembly. After the rodless cylinder 10 is ventilated, the slide of the rodless cylinder 10 drives the drive plate 14, thereby causing the bottom tray 13 to move laterally along the linear guide rail 10.

[0032] like Figure 1As shown, sensing components are installed on both sides of the profile frame 6 along its length to detect the position of the hopper, provide limit signals to the control system, and realize automated control.

[0033] The sensing component includes a shaft support 5, on which an optical axis 3 is mounted. Several fixing clips 4 are mounted on the shaft of the optical axis 3 to facilitate the adjustment of the position of the through-beam sensor 2. Each fixing clip 4 is equipped with an through-beam sensor 2. Two through-beam sensors 2 correspond to the upper and lower material hoppers, respectively. The through-beam sensors 2 are core detection components and are used in pairs. When the material hopper moves to the point where it blocks the light beam between the through-beam sensors 2, a signal is generated. Each material layer has a corresponding through-beam sensor to detect its position.

[0034] like Figure 1 As shown, the perimeter of the profile frame 6 is equipped with a quick-release protective sheet metal. Limiting plates 8 are installed on opposite sides of the two sides of the profile frame 6 to physically restrict the movement of the hopper, forming a key point to prevent the hopper from sliding off the track or colliding with the profile frame 6, and to provide mechanical hard limit protection. Quick-release handles 24 are installed on the limiting plates 8.

[0035] The bottom layer of the profile frame 6 is equipped with a solenoid valve 9 and a relay box 7. The solenoid valve 9 is used to control the compressed air to the pneumatic control element of the rodless cylinder 12, receive electrical signals from the control system, quickly switch the air path, thereby controlling the extension and retraction of the rodless cylinder 12, and is the execution switch of the rodless cylinder 12.

[0036] The relay box 7 is mainly used for signal and power conversion and distribution. In the future, the power and signal lines of the autonomous control cabinet will be distributed to various parts that need power. At the same time, the signals from the through-beam sensor will be collected and transmitted back to the control system.

[0037] Workflow:

[0038] Step 1: Before the dual-layer cylinder-driven material exchange hopper is put into use, the operator needs to load materials into the upper and lower hoppers according to production requirements, and set material parameters and exchange trigger conditions through the control system. The profile frame is divided into an initial station and a loading station. At this time, both the upper and lower hoppers are in the initial feeding station. The upper hopper is precisely connected to the loading station of the production line, while the lower hopper waits below. The entire mechanism completes the preparation work before startup.

[0039] Step 2: After the equipment is started, the rodless cylinder 12 of the upper hopper will operate to transport the material in the upper hopper to the loading station;

[0040] Step 3: After the material in the upper hopper is processed, the control system issues a command to start the double-layer cylinder drive exchange program. The entire mechanism begins to enter the hopper exchange process. The upper hopper moves along the high-precision linear guide 10 to the unloading station (that is, the initial station) to make room for the lower hopper to rise. The lower hopper moves along the high-precision linear guide 10 to the loading station.

[0041] Step 4: After the lower silo is positioned and starts feeding, the operator can replenish the upper silo. After replenishment, the upper silo stands by, waiting for the next exchange instruction. The entire workflow forms a cycle, continuously providing a stable supply of materials to the production line.

[0042] Step 5: Two sets of through-beam sensors are installed on the workpiece's position path. When the workpiece passes through, the sensors detect whether the manual loading is in place. If the workpiece is too high, an alarm is triggered, the pallet is returned, and the manual inspection and handling are reminded.

[0043] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
