When the first transfer platform is in the receiving position, the other end of the first transfer platform is connected to the first feeding ramp. When the first transfer platform is in the discharging position, the other end of the first transfer platform is connected to the first discharging ramp.

[0006] In some embodiments, the discharge end of the first feeding ramp is closer to the first transfer platform than the inlet end, and the height of the inlet end of the first feeding ramp is higher than the height of the discharge end.

[0009] In some embodiments, the first transfer platform is rotatably provided with a plurality of spaced third rollers along its transport path.

[0010] In some embodiments, the first transfer assembly further includes a first buffer roller disposed on the frame, the first buffer roller being used to abut against a material box that slides from the free end of the first transfer platform into the rotating end.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] To address the problem in existing technologies where material racks require frequent loading and unloading of material boxes after all parts have been removed, resulting in low work efficiency and wasted time and effort for workers, this invention provides a double-layer automatic loading and unloading material rack. This rack enables automatic material box circulation, eliminating the need for frequent handling of material boxes, thus improving material retrieval efficiency and reducing labor intensity.

[0019] It should be noted that the double-layer automatic loading and unloading material rack described in this utility model is used for, but not limited to, material boxes, etc. For ease of explanation, this utility model only uses the application of the double-layer automatic loading and unloading material rack to material boxes as an example for explanation. The principle of the double-layer automatic loading and unloading material rack applied to other types of equipment is essentially the same as that applied to material boxes, and will not be described in detail here.

[0020] Please see Figure 1 and Figure 2 , Figure 1This is a schematic diagram of the structure of a double-layer automatic loading and unloading material rack in one embodiment of the present invention. The double-layer automatic loading and unloading material rack includes a frame assembly 1 and a first transfer assembly 2. The frame assembly 1 includes a frame 11, a first loading ramp 12 and a first unloading ramp 13. The frame 11 has a first material picking station 14. The first loading ramp 12 and the first unloading ramp 13 are both inclined on the frame 11.

[0021] The first transfer assembly 2 includes a first drive unit 21 and a first transfer platform 22 connected to each other. One end of the first transfer platform 22 is rotatably connected to the frame 11 to switch between a receiving position and a discharging position. When the first transfer platform 22 is in the receiving position, the other end of the first transfer platform 22 is connected to the first loading ramp 12; when the first transfer platform 22 is in the discharging position, the other end of the first transfer platform 22 is connected to the first unloading ramp 13.

[0022] In this embodiment, the frame 11 is the basic structure of the entire material rack. The frame 11 can be welded from high-strength steel to ensure sufficient stability and load-bearing capacity. The frame 11 has a rectangular frame structure, and its height, width, and length can be designed according to the actual usage scenario and the size of the material box. The frame 11 is provided with a first material picking station 14, which is located in the middle of the left end of the frame 11, making it convenient for workers to pick up materials from the material box 4 at the first material picking station 14.

[0023] The first feeding ramp 12 is installed at an angle on the frame 11. Its inclination angle can be optimized according to the sliding performance of the material box 4 and the effect of gravity, and is usually 15°-30°. The inlet end of the first feeding ramp 12 is located at a higher position, and the outlet end is located at a lower position and close to the first transfer platform 22. Multiple first rollers 121 are installed on the conveying path of the first feeding ramp 12. These rollers are arranged at intervals to reduce the friction of the material box during the sliding process and ensure that the material box can slide smoothly from the inlet end to the outlet end.

[0024] The first feeding ramp 12 and the first discharging ramp 13 have similar structures and functions, but are positioned oppositely. The first discharging ramp 13 is installed at an angle below the first feeding ramp 12. The inlet end of the first discharging ramp 13 is at a higher position and close to the first transfer platform 22, while the outlet end is at a lower position and far from the first transfer platform 22. Multiple second rollers 131 are installed on the conveying path of the first discharging ramp 13. These rollers are arranged in the same way as the first rollers 121 to reduce the friction of the material box during the sliding process, ensuring that the material box can slide smoothly from the inlet end to the outlet end.

[0025] The first driving component 21 can be a motor drive device, installed on the side of the frame 11, used to drive the first transfer platform 22 to switch between the receiving position and the unloading position. The motor is a high-precision stepper motor, which can accurately control the rotation angle and speed of the first transfer platform 22.

[0026] The first transfer platform 22 is a rectangular flat plate structure, with one end rotatably connected to the frame 11 via a rotating shaft. The other end of the first transfer platform 22 is used to connect with the first feeding ramp 12 and the first discharging ramp 13. When the first transfer platform 22 is in the receiving position, its other end connects with the discharge end of the first feeding ramp 12, at which time the material box on the first feeding ramp 12 can slide into the first transfer platform 22 from the discharge end of the first feeding ramp 12.

[0027] After all the parts have been removed from the hopper of the first transfer platform 22, the hopper needs to be sent to the first unloading ramp 13 to remove the empty hopper. At this time, the first drive unit 21 drives the first transfer platform 22 to rotate to the unloading position. In the unloading position, the other end of the first transfer platform 22 connects to the inlet end of the first unloading ramp 13. The hopper can slide from the first transfer platform 22 into the inlet end of the first unloading ramp 13 by its own gravity, and then slide to the outlet end by gravity. Then, the corresponding robotic arm is used to remove the empty hopper.

[0028] Through the above design, the double-layer automatic loading and unloading material rack of this utility model can realize the automatic flow of material boxes, eliminating the need for frequent manual handling of material boxes 4, significantly improving material retrieval efficiency and reducing labor intensity. At the same time, by rationally designing the structure and function of each component, the operational stability and reliability of the entire material rack are ensured.

[0029] In one embodiment, please refer to Figure 2 The discharge end of the first feeding ramp 12 is closer to the first transfer platform 22 than the inlet end, and the height of the inlet end of the first feeding ramp 12 is higher than the height of the discharge end. The conveying path of the first feeding ramp 12 has multiple spaced and rotatably arranged first rollers 121. In this embodiment, the arrangement of the first rollers 121 allows the material box 4 filled with parts to slide smoothly on the first feeding ramp 12, reducing friction and improving the conveying efficiency of the material box 4. Simultaneously, the inclined design of the first feeding ramp 12 utilizes gravity, allowing the material box 4 to automatically slide from the inlet end to the outlet end without additional power, saving costs.

[0030] In one embodiment, please refer to Figure 2The first feeding ramp 12 has multiple limiting bars 122 spaced along its conveying path. Each limiting bar 122 is slidably connected to the first feeding ramp 12 to block or release the material boxes on the first feeding ramp 12. In this embodiment, the first feeding ramp 12 can hold multiple material boxes 4 filled with parts. Each limiting bar 122 is used to block one material box 4. The setting of the limiting bars 122 can effectively control the position of the material boxes, prevent multiple material boxes 4 from sliding at the same time and causing collisions or accumulation, and ensure that multiple material boxes 4 can reach the first transfer platform 22 one by one. After the previous material box is successfully unloaded, the next limiting bar 122 can be controlled to retract to release the corresponding material box 4, and so on, releasing multiple material boxes 4 one by one, which is beneficial to the sequential operation of the work.

[0031] In one embodiment, please refer to Figure 2 The inlet end of the first feeding ramp 13 is closer to the first transfer platform 22 than the outlet end, and the height of the inlet end of the first feeding ramp 13 is higher than the height of the outlet end. The conveying path of the first feeding ramp 13 has multiple spaced and rotatably arranged second rollers 131. In this embodiment, the first feeding ramp 13 is similar to the first loading ramp 12. The arrangement of the second rollers 131 is also to reduce the friction of the material box 4 on the first feeding ramp 13, allowing the material box to slide smoothly. The inclined design of the first feeding ramp 13 also utilizes gravity, allowing the empty material box after picking up parts to automatically slide from the inlet end to the outlet end, realizing the automatic feeding process of the material box 4.

[0032] In one embodiment, please refer to Figure 2 The first transfer platform 22 is equipped with multiple spaced third rollers 221 that rotate along its conveying path. The third rollers 221 allow the material box to slide smoothly on the first transfer platform 22, preventing jamming or shifting during transfer and ensuring the material box can be smoothly transferred from the first loading ramp 12 to the first unloading ramp 13. Furthermore, the spacing of the third rollers 221 can be adjusted according to the size and weight of the material box to accommodate different specifications, improving the versatility and applicability of the material rack.

[0033] In one embodiment, please refer to Figure 2 The first transfer assembly 2 also includes a first buffer roller 23 disposed on the frame 11. The first buffer roller 23 is used to abut against the material box that slides from the free end of the first transfer platform 22 into the rotating end. The first buffer roller 23 provided in this embodiment can effectively buffer the impact force when the material box slides into the first transfer platform 22, prevent the material box from being damaged by collision due to excessive speed, and at the same time reduce the wear of the material box on the first transfer platform 22, thus extending the service life of the material rack.

[0034] In one embodiment, please refer to Figure 2The double-layer automatic loading and unloading material rack also includes a second transfer component 3, which is located above the first transfer component 2. The rack assembly 1 also includes a second loading ramp 15 and a second unloading ramp 16. Both the second loading ramp 15 and the second unloading ramp 16 are inclined on the rack body 11, and the discharge end of the second loading ramp 15 and the inlet end of the second unloading ramp 16 are used to connect to the second transfer component 3. The second transfer component 3 set in this embodiment enables the material rack to realize the double-layer automatic loading and unloading function, further improving the storage capacity and working efficiency of the material rack. By reasonably designing the inclination angle and position of the second loading ramp 15 and the second unloading ramp 16, the automatic flow of the material boxes on the second layer can be realized, improving the utilization rate of the material boxes. The parts contained in the first layer material boxes and the second layer material boxes in this embodiment can be different types of parts. When the two types of material boxes are located at the corresponding picking stations, the workers can pick up the corresponding parts from the two types of material boxes, which is convenient to use.

[0035] In one embodiment, please refer to Figure 2 The second transfer component 3 includes a second drive member 31 and a second transfer platform 32 connected to each other. The frame 11 has a second material handling station 17. The second transfer platform 32 is vertically slidably connected to the frame 11 to connect with the second loading ramp 15 or the second unloading ramp 16. In this embodiment, the second drive member 31 is used to drive the second transfer platform 32 to slide in the vertical direction, realizing the connection between the second transfer platform 32 and the second loading ramp 15 or the second unloading ramp 16. Specifically, the second drive member 31 can be a drive cylinder, which is used to drive the second transfer platform 32 to slide up and down, so that the second transfer platform 32 can connect with the second loading ramp 15 or the second unloading ramp 16. When the second transfer platform 32 is connected to the second loading ramp 15, the material box can slide from the second loading ramp 15 into the second transfer platform 32; when the parts in the material box are removed, the second transfer platform 32 can be connected to the second unloading ramp 16, and the material box can slide from the second transfer platform 32 into the second unloading ramp 16 to complete the removal of the empty material box.

[0036] In one embodiment, please refer to Figure 2The second unloading ramp 16 is located above the second loading ramp 15. The inlet end of the second unloading ramp 16 is closer to the second transfer platform 32 than the outlet end, and the height of the inlet end of the second unloading ramp 16 is higher than the height of the outlet end. Similarly, the outlet end of the second loading ramp 15 is closer to the second transfer platform 32 than the inlet end, and the height of the inlet end of the second unloading ramp 16 is higher than the height of the outlet end. In this embodiment, the material box flow direction of the second loading ramp 15 and the second unloading ramp 16 is opposite to that of the first loading ramp 12 and the first unloading ramp 13. The second loading ramp 15 is used for the material box containing parts to slide into the second transfer platform 32, and the second unloading ramp 16 is used for empty material boxes to slide out of the rack. The space above the second unloading ramp 16 and the second loading ramp 15 can be fully utilized to increase the storage capacity of the material rack.

[0037] In one embodiment, please refer to Figure 2 and Figure 3 The frame assembly 1 also includes a limiting flange 18 disposed on the frame 11. When the second transfer platform 32 slides from the second loading ramp 15 to the second unloading ramp 16 and abuts against the limiting flange 18, the second transfer platform 32 can rotate relative to the frame 11 with the limiting flange 18 as the rotation axis. The limiting flange 18 can guide the second transfer platform 32 so that after the second transfer platform 32 rotates and adjusts its angle, the second transfer platform 32 can remain flush with the second unloading ramp 16, ensuring that the second transfer platform 32 can accurately connect with the second unloading ramp 16, and the material box on the second transfer platform 32 can smoothly slide from the second transfer platform 32 into the second unloading ramp 16, completing the unloading of the material box.

[0038] The frame 11 has a vertical rod 111 and a horizontal rod 112. The second transfer platform 32 is rotatably connected to the horizontal rod 112 via a bearing 321. The horizontal rod 112 is slidably connected to the vertical rod 111 of the frame 11 via a slider 19, so that the second transfer platform 32 can rise and fall smoothly. When the material box moves upward until the edge of the material box abuts the limiting flange 18, the limiting flange 18 limits the movement of the second transfer platform 32. As the second transfer platform 32 continues to rise, it rotates, and the end of the second transfer platform 32 away from the limiting flange 18 tilts upward until the second transfer platform 32 is flush with the second unloading inclined plate 16.

[0039] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail below: The double-layer automatic loading and unloading material rack provided by this utility model achieves continuous, unmanned flow of the material box from the first loading ramp 12 to the first loading ramp 22 and then from the first loading ramp 22 to the first unloading ramp 13 by automatically flipping the first transfer platform 22 between the receiving position and the unloading position. When the material box is located on the first loading ramp 22, the worker can continuously pick up parts at the first picking station. After the material box is picked up, the first loading ramp 22 rotates to the unloading position, and the empty box slides off automatically. The first loading ramp 22 then rotates to the receiving position, and the new box is automatically replenished. There is no need for frequent manual handling of the material box, which significantly improves the picking efficiency and reduces labor intensity.
