Description

Technical Field

[0001] This utility model belongs to the technical field of automated logistics transportation, and in particular relates to a multi-layer warehouse docking and unloading rack. Background Technology

[0002] In factory warehousing environments, high-bay racks are commonly used, requiring logistics personnel to retrieve material boxes from different heights, which is labor-intensive and poses safety hazards. Centralizing material boxes of varying heights at a single outlet would reduce labor intensity.

[0003] Existing technologies include, for example, Chinese utility model patent application number CN202421324191.2, entitled "An Automatic Material Rack". It includes an infeed rack, an outfeed rack, a feeding box, an automatic shut-off assembly, and an automatic lifting and tilting assembly. The infeed rack and outfeed rack have the same structure and are both set at an inclined angle on the frame. The infeed rack includes at least two layers and has rolling pulleys in the middle. The outfeed rack tilts in the opposite direction to the infeed rack and also has rolling pulleys in the middle. An automatic shut-off assembly is set above the infeed rack. The automatic shut-off assembly includes a shut-off cylinder, a shut-off lever, a fulcrum shaft, and a shut-off plate. The automatic lifting and tilting assembly includes a feeding platform, a guide rod and guide sleeve assembly, a lifting cylinder, a tilting frame, and a telescopic cylinder. This automatic material rack uses feeding to slide down stably with the assistance of rolling pulleys, sliding from the infeed rack to the feeding platform, and then sliding down to the outfeed rack after the tilting frame adjusts the tilt angle, completing one product feeding and empty discharge process. In conjunction with the lifting cylinder, it can switch feeding between two or even more layers of infeed racks. This patent uses a lifting cylinder in conjunction with a telescopic cylinder to complete the position and angle adjustment of the tilting frame.

[0004] The existing tilting rack has an overly complicated position and angle adjustment process and uses two types of cylinders as power sources. Therefore, a multi-layer storage docking and unloading rack with a simple structure, low cost, and reduced energy consumption is needed. Utility Model Content

[0005] In view of this, the present invention aims to propose a multi-layer warehouse docking and unloading rack that is simple in structure, low in cost, and reduces energy consumption.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-layer storage docking and unloading rack includes: a frame, an upper-layer conveying mechanism, a lower-layer conveying mechanism, and a first flipping component, all integrated on the frame, wherein the upper-layer conveying mechanism and the lower-layer conveying mechanism are respectively inclined.

[0008] The first flipping component includes a flipping frame and two rope pulley mechanisms. The rear end of the flipping frame, away from the upper transmission mechanism, is rotatably connected to the frame. The flipping frame has three sides to surround the material box.

[0009] Initially, the flipping frame receives the hopper sliding down from the upper conveying mechanism and then flips downward to allow the material to fall into the lower conveying mechanism. The rope pulley mechanism is used to control the flipping frame to reset after flipping.

[0010] Two rope pulley mechanisms are respectively arranged on the left and right sides of the flipping frame. Each rope pulley mechanism includes a rope, a pulley, a slider, and a counterweight. The pulley is arranged on the frame. The path of the rope is n-shaped. One end of the rope is fixed to the top edge of the flipping frame. The other end of the rope passes upward and forward through the pulley and is then fixed downward to the slider. The slider is vertically slidably connected to the frame. The counterweight and the slider are fixed.

[0011] Furthermore, it also includes an interception mechanism for intercepting the output end of the lower transmission mechanism. The interception mechanism includes a rectangular frame that slides up and down with the frame. The rectangular frame is provided with an interception plate for intercepting the material box. The bottom of the rectangular frame is fixed with a tilting rod that is tilted left and right.

[0012] The docking trolley that receives the upper material box of the lower transmission mechanism is equipped with a contact block that can contact the bottom surface of the tilting rod. The movement of the docking trolley causes the contact block to lift the tilting rod.

[0013] Furthermore, it also includes a third-layer transfer mechanism and a second flipping component integrated on the frame. The third-layer transfer mechanism is located below the lower-layer transfer mechanism, and the second flipping component is used to receive the material box on the lower-layer transfer mechanism and transfer the material box to the third-layer transfer mechanism. The second flipping component and the first flipping component have the same structure.

[0014] Furthermore, a limit rod is fixed on the frame, which can abut against the front end of the flipping frame after it has been flipped, in order to limit the downward flipping angle of the flipping frame.

[0015] Furthermore, a limit rod is fixed on the frame, which can limit the upward position of the slider.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This novel multi-layer storage rack design allows for easy adjustment of the tilting frame angle using only a rope pulley mechanism, eliminating the need for vertical adjustment. When a bin slides into the tilting frame, the weight of the bin and its contents exceeds the weight of the counterweight. The tilting frame tilts downwards, and the slider moves upwards. Once the tilting frame reaches its position, the bin slides into the lower slide, at which point the slider moves downwards, and the tilting frame tilts back to its original position. The rack utilizes the principles of counterweight and tilting, achieving orderly flow of bins from the upper to the lower layer through the combined weight of the bins and their contents, thus meeting the factory's first-in, first-out (FIFO) requirement. The rope pulley mechanism eliminates the need for pneumatic or electric power, offering advantages such as energy saving and cost reduction. Furthermore, the rope pulley mechanism is small in size and simple in structure. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] See appendix Figure 1-4 Description of this embodiment: A multi-layer warehouse docking and unloading rack, characterized in that it includes: a frame, an upper layer transmission mechanism 1, a lower layer transmission mechanism 2 and a first flipping component respectively integrated on the frame, wherein the upper layer transmission mechanism 1 and the lower layer transmission mechanism 2 are respectively inclined.

[0028] The frame serves as the mounting base for all components of the multi-layer warehouse docking and unloading rack.

[0029] The upper conveying mechanism 1 is inclined downward from front to back, and the lower conveying mechanism 2, which is inclined downward from back to front, is arranged vertically. The upper conveying mechanism 1 and the lower conveying mechanism 2 can convey the material box by means of flow strips.

[0030] The first tilting component is located at the rear end of the frame, behind the upper conveying mechanism 1 and the lower conveying mechanism 2. Specifically, it includes a tilting frame 3 and two rope pulley mechanisms. The rear end of the tilting frame 3, away from the upper conveying mechanism 1, is rotatably connected to the frame. The tilting frame 3 has three sides to surround the material box, meaning it is open at the front, with the opening facing the upper conveying mechanism 1. These three sides act as material interceptors, allowing the material box to fall onto the bottom surface of the tilting frame 3. Two flow bars are provided on the bottom surface of the tilting frame 3. The rear end of the bottom surface of the tilting frame 3 is rotatably connected to the frame, and the front end of the tilting frame 3 can rotate downwards, allowing the tilting frame 3 to switch between the upper conveying mechanism 1 and the lower conveying mechanism 2. Figure 3 As shown, the rear end of the flip frame 3 is fixed with two rotating sleeves 31, each of which is fitted onto the frame and can rotate.

[0031] Initially, the flipping frame 3 receives the material box sliding down from the upper conveying mechanism 1 and flips downward to allow the material to fall into the lower conveying mechanism 2. The rope pulley mechanism is used to control the flipping frame 3 to reset after flipping.

[0032] Two rope pulley mechanisms are respectively set on the left and right sides of the tilting frame 3. Each rope pulley mechanism includes a rope, a pulley 4, a slider 5, and a counterweight 6. The pulley 4 is set on the frame, which can be located at the top of the frame, and the pulley 4 is located behind the slider 5. The rope path is n-shaped. One end of the rope is fixed to the top edge of the tilting frame 3, that is, the top edge of the left or right side of the tilting frame 3. Preferably, it is located in the middle and rear of the top edge of the left or right side, so that the rope travel range is small and the control is more stable. The other end of the rope goes up and forward through the pulley 4 and then is fixed downward to the slider 5. The slider 5 is vertically slidably connected to the frame, and the counterweight 6 is fixed to the slider 5. One slider 5 is slidably connected to each side of the frame. The weight of the counterweight 6 is greater than that of the tilting frame 3, so that the initial position of the tilting frame 3 is lifted and can be connected to the upper transmission mechanism 1. After the tilting frame 3 receives the material box, the front end flips downward, driving one end of the rope and the rear end to descend; the other end of the rope and the slider 5 rise. When the flipping frame 3 flips to the position corresponding to the lower conveying mechanism 2, the material box automatically falls into the lower conveying mechanism 2 under the action of gravity.

[0033] The material bins can be transferred at intervals by the upper conveyor mechanism 1, and then transferred by the flipping frame 3 to the lower conveyor mechanism 2. When there are no intervals between the material bins on the upper conveyor mechanism 1, a movable blocking rod can be placed at the output end of the upper conveyor mechanism 1. The blocking rod can block the material bins on the upper conveyor mechanism 1 or remove them from the material bins to release them. The blocking rod can be installed on an electric push rod, which is mounted on the frame.

[0034] Preferably, it also includes an interception mechanism for intercepting the output end of the lower transmission mechanism 2. The interception mechanism includes a rectangular frame 71, which slides up and down with the frame. The rectangular frame 71 is provided with an interception plate 72 for intercepting the material box. The bottom of the rectangular frame 71 is fixed with a tilting rod 73 that is tilted left and right. The rectangular frame 71 is located at the front end of the frame.

[0035] The docking trolley receiving the upper material box of the lower-level transfer mechanism 2 is equipped with a contact block that can contact the bottom surface of the tilting rod 73. The movement of the docking trolley causes the contact block to lift the tilting rod 73. The shape of the contact block can be the same as the tilt angle of the bottom surface of the tilting rod 73, but the top surface of the contact block is higher than the lowest point of the tilting rod 73. The contact block can move left and right to lift the tilting rod 73. The contact block can also be a vertical rod, higher than the lowest point of the tilting rod 73.

[0036] Preferably, it further includes a third-layer transfer mechanism 8 and a second flipping component integrated on the frame. The third-layer transfer mechanism 8 is located below the lower-layer transfer mechanism 2, and the second flipping component is used to receive the material box on the lower-layer transfer mechanism 2 and transfer the material box to the third-layer transfer mechanism 8. The second flipping component has the same structure as the first flipping component. The first flipping component is horizontally rotated 180 degrees and installed between the lower-layer transfer mechanism 2 and the third-layer transfer mechanism 8.

[0037] The front end of the flipping frame of the second flipping component is rotatably connected to the machine frame. The two rope pulley mechanisms of the second flipping component are respectively set on the left and right sides of the flipping frame of the second flipping component. Each rope pulley mechanism includes a rope, a pulley, a slider and a counterweight. The pulley is set on the machine frame. The path of the rope is n-shaped. One end of the rope is fixed to the top edge of the flipping frame of the second flipping component. The other end of the rope goes up and back through the pulley and then down to the slider. The slider is vertically slidably connected to the machine frame. The counterweight and the slider are fixed.

[0038] Similarly, an interception mechanism can be set at the output of the third-layer transmission mechanism 8.

[0039] To accommodate heavy hoppers and prevent them from falling off the tilting frame, limit rods or angle limit rods can be used to determine the tilting position of the tilting frame.

[0040] Preferably, a limiting angle rod (not shown in the figure) is fixed on the frame. The limiting angle rod abuts against the front end of the flipping frame 3 after it has been flipped, thereby limiting the downward flipping angle of the flipping frame 3. The limiting angle rod can fix the flipping angle of the flipping frame 3, allowing it to accurately align with the lower transmission mechanism.

[0041] Preferably, a limit rod (not shown in the figure) is fixed on the frame, and the limit rod can limit the rising position of the slider 5.

[0042] The embodiments of the present invention disclosed above are merely illustrative of the present invention. The embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention.
