These equipment are typically installed on automated warehousing equipment such as stacker cranes and warehouse robots for automated loading and unloading of materials.

[0003] In the prior art, Chinese utility model patent CN117585346A discloses a collaborative shelving robot and method. Specifically, it includes a first loading / unloading component and a second loading / unloading component used in conjunction. Both the first and second loading / unloading components include a column, a lifting mechanism, and a loading / unloading mechanism. The column is connected to the loading / unloading mechanism through the lifting mechanism. The column is equipped with a shelving traveling mechanism, which cooperates with a guide rail fixed to the shelving so that the first and second loading / unloading components can move independently along the guide rail. The loading / unloading mechanism includes a loading component connected to the lifting mechanism. The loading component is connected to forks through a telescopic mechanism and adopts a stacking structure. The forks push the boxes on the shelving to the loading platform or push the boxes from the loading platform to the designated storage location on the shelving via levers. In this process, because the forks need to extend to both sides of the boxes to clamp them, a large spacing is required between adjacent boxes on the shelving, reducing storage density and increasing storage costs.

[0004] To address the aforementioned technical problems, Chinese utility model patent CN113830486A discloses a bidirectional loading and unloading device and its equipment. Specifically, the loading and unloading device includes: a loading and unloading frame; a slide rail fixed to the loading and unloading frame; a loading and unloading slider that can only move along the slide rail; a dragging assembly that controls the movement of the loading and unloading slider via a dragging motor; a swing motor fixed to the loading and unloading slider; a reducer whose housing is fixed to the loading and unloading slider, and whose input shaft is connected to the rotating shaft of the swing motor; a swing rod, one end of which is fixed to the output shaft of the reducer; a gripping motor, the housing of which is fixed to the other end of the swing rod; and a gripping hook fixed to the rotating shaft of the gripping motor. The controller controls the swing rod to swing towards either of the two shelves via the swing motor, controls the gripping hook to grip the edge of the cargo box via the gripping motor, and drags the cargo box onto the loading and unloading frame via the dragging motor, or reverses the operation to push the cargo box on the loading and unloading frame into the shelf. It uses a hook-and-pull structure to store materials such as bins, which reduces the distance between bins. However, its structure is complex and requires a large number of motors, which undoubtedly increases the manufacturing cost and thus the user's operating cost, which is not conducive to the promotion and application of the above-mentioned loading and unloading device in the market.

Therefore, they should not be construed as limitations on this utility model.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] Example 1: Figures 1 to 7As shown, a warehousing and logistics storage and retrieval device is mainly used for storing and retrieving material boxes 7 with grooves. The grooves are set at both ends of the material box 7 to avoid affecting the sides of the material box 7, reduce the spacing between adjacent material boxes 7, increase storage density, and reduce storage costs. In this embodiment, the storage and retrieval device mainly consists of a bottom support 6, a storage and retrieval mechanism 2, and a loading mechanism 3 with loading and unloading motors 3-4. Both the storage and retrieval mechanism 2 and the loading mechanism 3 are installed on the bottom support 6. The bottom support 6 is designed to facilitate the installation of the storage and retrieval mechanism 2 and the loading mechanism 3, thereby ensuring the stability of the storage and retrieval device during use. The storage and retrieval mechanism 2 is designed to hook and push the material box 7 for storage and retrieval. The loading mechanism 3 is designed to move the material box 7 and provide support for it. The aforementioned storage and retrieval mechanism 2 mainly consists of a first rotating push-pull rod 2-1, a second rotating push-pull rod 2-2, a push-pull rod drive assembly, and a moving assembly. The ends of the first rotating push-pull rod 2-1 and the second rotating push-pull rod 2-2 are formed with hooks that fit into grooves formed at the ends of the material box 7. These hooks can engage with the grooves in the material box 7, thereby enabling the storage and retrieval operation of the material box 7. The push-pull rod drive assembly is used to drive the angle adjustment between the first rotating push-pull rod 2-1 and the second rotating push-pull rod 2-2. The purpose is to increase the distance between the first rotating push-pull rod 2-1 and the second rotating push-pull rod 2-2 to ensure the stability of the material box 7 during position movement and reduce the probability of the material box 7 falling. The aforementioned movable component is used to move the positions of the first rotary push-pull rod 2-1 and the second rotary push-pull rod 2-2. The push-pull rod drive component is installed on the movable component to drive the position of the material box 7, that is, by moving the positions of the first rotary push-pull rod 2-1 and the second rotary push-pull rod 2-2, the material box 7 is pulled onto the loading mechanism 3. In order to adapt to the aforementioned storage and retrieval component 2, the loading component 3 is installed on the side of the aforementioned storage and retrieval component 2.

[0027] Specifically, the push-pull rod drive assembly in this embodiment mainly consists of a pair of meshing gears 2-4 and a push-pull rod motor 2-3. To adjust the opening angle of the first rotary push-pull rod 2-1 and the second rotary push-pull rod 2-2, the first rotary push-pull rod 2-1 and the second rotary push-pull rod 2-2 are respectively mounted on a pair of gears 2-4. In this embodiment, there are two rotary push-pull rods, namely the first rotary push-pull rod 2-1 and the second rotary push-pull rod 2-2. The two rotary push-pull rods achieve symmetrical movement through a pair of meshing gears 2-4, thereby maintaining stability when pushing and pulling the material box 7.

[0028] To ensure the stability of the push-pull rod motor 2-3 during installation and use, the push-pull rod motor 2-3 is mounted on the first bracket 2-5. The gear 2-4 is mounted on the top of the first bracket 2-5. The shaft of the push-pull rod motor 2-3 is connected to one of the gears 2-4. The push-pull rod motor 2-3 drives one of the gears 2-4 to rotate, which in turn drives the other gear 2-4 to rotate. This causes the angle between the ends of the first rotating push-pull rod 2-1 and the second rotating push-pull rod 2-2, which are fixed on the gear 2-4, to increase or decrease. The angle can also be a reverse angle greater than 180°, used to hook the material box 7 on the other side.

[0029] In order to move the material box 7 onto the loading mechanism 3, in this embodiment, the aforementioned moving component is installed at the bottom of the first bracket 2-5 to move the positions of the first rotating push-pull rod 2-1 and the second rotating push-pull rod 2-2, thereby realizing the movement of the material box 7. The aforementioned moving component mainly consists of a linear guide rail 2-6, a guide rail base 2-7, a second bracket 2-8, a first synchronous pulley 2-9, a first synchronous belt 2-10, a second synchronous pulley 2-11, and a slider 2-12. The slider 2-12 is slidably mounted on the linear guide rail 2-6. A linkage seat 2-13 for linking the slider 2-12 and the first synchronous belt 2-10 is installed at the bottom of the first bracket 2-5. The guide rail base 2-7 is installed below the guide rail 2-6 to fix the guide rail 2-6. The second bracket 2-8 is installed on one side of the linear guide rail 2-6, and the first synchronous pulley 2-9 and the second synchronous pulley 2-11 are both installed on the other side of the linear guide rail 2-6. The first synchronous belt 2-10 is fitted over the first synchronous pulley 2-9 and the second synchronous pulley 2-11, and the first synchronous belt 2-10 is tensioned by the first synchronous pulley 2-9 and the second synchronous pulley 2-11, thereby ensuring the stability of the moving component during the movement process, and thus ensuring the stability of the material box 7.

[0030] The cargo-carrying mechanism 3 in this embodiment further includes a second synchronous belt 3-1, a third synchronous belt 3-2, a loading / unloading reducer 3-3, a second cargo-carrying bracket 3-6, a first cargo-carrying bracket 3-7, a synchronous belt connecting rod shaft 3-9, a third synchronous belt pulley 3-10, a fourth synchronous belt pulley 3-11, a fifth synchronous belt pulley 3-12, and a sixth synchronous belt pulley 3-13. The second synchronous belt 3-1 is installed close to the first cargo-carrying bracket 3-7, the third synchronous belt 3-2 is installed close to the second cargo-carrying bracket 3-6, and the loading / unloading reducer 3-3 is installed on the loading / unloading motor 3. At the output end of the -4, the aforementioned synchronous belt connecting rod shaft 3-9 is installed at the output end of the aforementioned loading and unloading reducer 3-3 and passes through the aforementioned second cargo support 3-6 and the aforementioned first cargo support 3-7. The aforementioned third synchronous pulley 3-10 and the aforementioned fourth synchronous pulley 3-11 are both fitted outside the aforementioned synchronous belt connecting rod shaft 3-9. The aforementioned second synchronous belt 3-1 is fitted outside the aforementioned third synchronous pulley 3-10 and the aforementioned fifth synchronous pulley 3-12. The aforementioned third synchronous belt 3-2 is fitted outside the aforementioned fourth synchronous pulley 3-11 and the aforementioned sixth synchronous pulley 3-13. The aforementioned first synchronous pulley 2-9, third synchronous pulley 3-10, fourth synchronous pulley 3-11 and the output shaft of the aforementioned loading and unloading reducer 3-3 are connected through the aforementioned synchronous belt connecting rod shaft 3-9 and are synchronously driven by the aforementioned loading and unloading motor 3-4.

[0031] To prevent the material box 7 from falling off, in this embodiment, a first loading baffle 3-8 is installed on the side of the second synchronous belt 3-1, and a second loading baffle 3-5 is installed on the side of the third synchronous belt 3-2. The height of the first loading baffle 3-8 is higher than that of the second synchronous belt 3-1, and the height of the second loading baffle 3-5 is higher than that of the third synchronous belt 3-2. The first loading baffle 3-8 is installed on the outside of the second synchronous belt 3-1, and the second loading baffle 3-5 is installed on the outside of the third synchronous belt 3-2. The distance between the first loading baffle 3-8 and the second loading baffle 3-5 is greater than the distance between the second synchronous belt 3-1 and the third synchronous belt 3-2.

[0032] To ensure the supporting effect and stability of the first cargo support 3-7 and the second cargo support 3-6, both are mounted on the bottom support 6. Photoelectric sensors are also installed on the first cargo support 3-7 and the second cargo support 3-6 to detect whether the material box 7 has reached the designated position during loading and unloading. The installation position of the photoelectric sensors is set as needed.

[0033] To facilitate the overall installation of the aforementioned storage and retrieval device on external equipment such as stacker cranes or warehouse robots, in this embodiment, a left connecting side plate 1 and a right connecting side plate 4 are also installed on the bottom support 6. The left connecting side plate 1 and the right connecting side plate 4 are located on both sides of the cargo-carrying assembly 3, respectively. Both the left connecting side plate 1 and the right connecting side plate 6 have connecting holes, and connectors for connecting to stacker cranes or warehouse robots are inserted into these connecting holes. The connectors can be simple in structure, economical, and practical, such as connecting bolts.

[0034] A warehousing and logistics storage and retrieval method includes the following steps:

[0035] When retrieving goods, S1, the push-pull rod motor 2-3 is started, which drives the gear 2-4 to rotate, thereby rotating the first rotating push-pull rod 2-1 and the second rotating push-pull rod 2-2 to a parallel and close position. The loading and unloading motor 3-4 pushes the storage and retrieval mechanism to hook the top hooks at the ends of the first rotating push-pull rod 2-1 and the second rotating push-pull rod 2-2 into the groove of the material box 7. S2, the push-pull rod motor 2-3 rotates in the opposite direction and drives the first rotating push-pull rod 2-1 and the second rotating push-pull rod 2-2 to the open position, and pulls the material box 7 to the storage and retrieval mechanism 2. S3, the loading and unloading motor 3-4 rotates in the opposite direction and pulls the material box 7 onto the loading mechanism 3 through the storage and retrieval mechanism 2. The material box 7 is supported by the first synchronous belt 2-10, the second synchronous belt 3-1, and the third synchronous belt 3-2.

[0036] When storing, S1 to S3 are reversed, and finally the first rotating push-pull rod 2-1 and the second rotating push-pull rod 2-2 are disengaged from the top hooks at the ends. The push-pull rod motor 2-3 then restores the first rotating push-pull rod 2-1 and the second rotating push-pull rod 2-2 to the open position.

[0037] Example 2: The difference between this example and Example 1 is that: in this example, a storage and retrieval device for warehousing and logistics has one rotating push-pull rod and one corresponding gear. The rotating push-pull rod is mounted on the gear, and the shaft of the loading and unloading motor 3-4 is connected to the gear to drive the gear to rotate, thereby changing the direction of the rotating push-pull rod and realizing operations such as hooking and pulling the material box 7.

[0038] Example 3: The feature that distinguishes this example from Example 1 is that: in this example, a storage and retrieval device for warehousing and logistics has multiple rotating push-pull rods, more than two, and the number of gears is adapted to the number of rotating push-pull rods. Specifically, the number of rotating push-pull rods can be set as needed and is not limited here.

[0039] To reduce the friction at the contact point between the top of the rotating push rod and the material box 7, a needle roller bearing can be used at the top of the rotating push rod. When the rotating push rod hooks the material box 7, the bearing surface of the needle roller bearing contacts the groove wall, reducing the contact area and thus reducing the friction.

[0040] The above embodiment describes a warehousing and logistics storage and retrieval device with an ingenious structure. It is mainly used for storing and retrieving grooved material boxes 7. By setting up a storage and retrieval mechanism 2 and a loading mechanism 3, the entire structure only uses two motors to realize the storage and retrieval of the material boxes 7, which reduces manufacturing costs and user operating costs. It can also effectively ensure the stability of the material boxes 7 during the storage and retrieval process, guarantee the use effect, enhance the user experience, and facilitate the promotion and application of the above-mentioned warehousing and logistics storage and retrieval device in the market.

[0041] The above description of the disclosed embodiments will enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
