Description

Technical Field

[0001] The present invention relates to the technical field of storage shelves, and in particular to a logistics storage intelligent shelf. Background Art

[0002] Warehouse shelves are storage equipment. More and more industries and enterprises are using them, and more and more enterprises are entering the warehousing industry. Warehouse shelves are one of the main facilities of warehousing and are an indispensable part of modern industrial warehouses, logistics centers, and distribution centers. However, the existing warehouse shelves have a single function and a simple structure.

[0003] A Chinese patent discloses "an intelligent logistics storage shelf system", application publication number CN117963389A. The invention includes a shelf unit and a storage trolley; a multi-layer transmission track is provided in the shelf unit; a lifting unit that can move to each layer of the transmission track is also provided at the end of the shelf unit; a carrying platform located inside the transmission port is provided on both sides of the upper end of the storage trolley. The invention transfers goods to each layer of the storage platform of the shelf unit by the storage trolley or unloads the goods on each layer of the storage platform from the shelf unit by using the storage trolley; when the carrying platform is higher than the storage platform, the carrying platform is lifted up and lowered. The cargo on the platform can be moved to the corresponding position on the storage platform by the drive of a storage trolley. After the cargo is transported to the designated position, the lifting column is lowered by a push rod so that the transport platform is lower than the storage platform. The cargo can then be stably placed on the storage platform for loading. The use of this system for logistics storage and transshipment has a higher degree of automation, realizing intelligent warehousing logistics. A Chinese patent application titled "A Forklift for Logistics and Warehousing, Working Method, and Logistics and Warehousing System" with application publication number CN119038454A discloses a forklift for logistics and warehousing, a working method, and a logistics and warehousing system. The forklift for logistics and warehousing includes a mobile base, a fork bracket and a lifting mechanism for driving the fork bracket to rise and fall, the fork bracket being provided with a fork assembly and a first drive mechanism for driving the fork assembly to extend and retract the fork bracket forward, the fork assembly including two forks arranged side by side, support wheels being provided on the front side of the bottom of the forks, and a second drive mechanism for driving the support wheels to rise and fall. When carrying goods on a shelf, the present invention supports the forks by contacting the shelf with the support wheels, thereby preventing the forklift from tipping over due to the forward shift of the center of gravity, reducing the force on the columns, avoiding bending deformation of the columns, and eliminating the need for counterweights, thereby reducing costs.

[0004] The above patent uses a storage trolley or a forklift to transfer goods. When laying out the shelves, sufficient operating space must be reserved for the storage trolley or forklift. Each shelf must correspond to the corresponding space planned for the storage trolley or forklift, which will result in a large amount of space waste. Due to the existence of the reserved space, the number of shelves that can be placed within the limited space is relatively small. This affects the effective utilization efficiency of the space to a certain extent, and may also have an adverse impact on the storage capacity and operating costs of the entire warehouse, and may also lead to problems such as increased storage costs per unit of goods. Summary of the Invention

[0005] The purpose of the present invention is to provide a logistics warehousing intelligent shelf, which aims to solve the problem in the prior art that sufficient operating space needs to be reserved for storage carts or forklifts, resulting in a large amount of space waste and reduced space utilization.

[0011] The driving assembly includes a first driving device fixed on the layer plate, four sprockets rotatably arranged on the support member, and a chain wound around the four sprockets;

[0012] One of the sprockets is in driving connection with the first drive device.

[0013] Preferably, a mounting base is fixed to the bottom of the placement plate, and the mounting base is provided with two rows of rollers that can rotate and adapt to the annular guide track, and the annular guide track is located between the two rows of rollers;

[0014] A connecting block is fixed to the bottom of the mounting seat, and the connecting block is fixedly mounted on the chain so that when the chain rotates, it can drive the placement plate to move evenly and synchronously.

[0015] Preferably, the positioning assembly includes a first telescopic device hingedly connected to the annular guide track, a rotating rod rotatably arranged on the outer surface of the annular guide track, a pendulum fixed to the rotating rod, and a connecting member provided between the rotating rod and the first telescopic device;

[0016] The lower end of the connecting member is hingedly connected to the movable section of the first telescopic device, and the upper end of the connecting member is fixedly sleeved on the rotating rod;

[0017] A limiting column is fixed on the top of the ornament, and a slot plate adapted to the limiting column is fixed on the mounting seat;

[0018] Angle steels are rotated at both ends of the rotating rod, and the angle steels are installed on the annular guide track.

[0019] Preferably, a photoelectric sensor is installed on the mounting seat, and a light shielding sheet is installed on the angle steel. When the light shielding sheet and the photoelectric sensor are triggered, the corresponding placement plate stops rotating.

[0020] Preferably, an electric hoist mechanism is fixed on the inner top wall of the lifting frame, and a hook plate connected to the electric hoist mechanism is fixed on the transfer platform, so that the transfer platform can be lifted up and down along the lifting frame.

[0021] Preferably, the traction assembly includes a rotating assembly mounted on the transfer platform and a rotating plate transmission-connected to the rotating assembly;

[0022] The traction assembly further includes a telescopic assembly mounted on the rotating plate, and a box body connected to the telescopic assembly in a transmission manner and with an opening facing upwards;

[0023] The traction assembly also includes a lifting assembly installed on the bottom wall of the box body and a load-bearing rod installed on the lifting assembly. After the load-bearing rod is inserted into the load-bearing plate, the goods are moved into the lifting frame under the action of the lifting assembly and the telescopic assembly.

Next, the first drive device is activated, driving the chain to rotate, causing the placement plate corresponding to the desired goods to rotate to the position corresponding to the positioning component and then stop. The positioning component then locks the placement plate. Finally, the goods are removed with the help of the traction component. Since sufficient operating space is not required for the transfer vehicle, more fixed frames for placing goods can be placed in this space, thereby improving space utilization.

[0033] 2. The entire device is designed so that when the placement plate rotates to a specific position aligned with the traction assembly, the positioning assembly automatically activates. At this point, the stopper pins in the positioning assembly precisely engage the slot plate, locking the placement plate in place. This function facilitates access to goods placed on the placement plate, improving work efficiency and convenience. It also prevents the placement plate from tilting or shifting during retrieval.

[0034] 3. The load-bearing rod is inserted into the cargo tray. Next, the lifting assembly propels the cargo on the tray, lifting it off the tray. Driven by the telescopic assembly, the cargo begins to move smoothly toward the lifting frame. The transfer platform then begins operating, driven by the electric hoist mechanism. With its powerful traction, the hoist mechanism steadily drives the transfer platform, slowly transporting the cargo already within the lifting frame downward. The cargo is smoothly transferred from a higher position to the easily accessible lower area, making it easier for workers to access the cargo on the fixed frame, greatly improving the efficiency of the entire transfer process.

[0046] The following is a further description of a specific implementation of a logistics warehousing intelligent shelf of the present invention with reference to the accompanying drawings.

[0047] like Figures 1-10 As shown, a logistics warehousing intelligent shelf is mainly used for placing fixed frames 1 of goods. When in use, it is not necessary to leave enough space for the transfer cart to move. Adjacent fixed frames 1 can be close to each other, which not only saves space but also enables more fixed frames 1 to be placed in the same space to accommodate more goods.

[0048] In this embodiment, the shelf includes several groups of fixed frames 1 that are spaced apart in the front-to-back direction and extend in the up-down direction. There are several groups of layer boards 2 on the fixed frames 1 that are spaced apart in the up-down direction and extend in the left-right direction. The fixed frames 1 can be placed side by side so that more fixed frames 1 can be placed. The arrangement of the layer boards 2 allows multiple layers to be arranged on the same fixed frame 1, so that more goods can be placed.

[0049] like Figure 1 and Figure 5-Figure 9 As shown, a circular guide track 3 extending in the left-right direction is fixed on the layer plate 2, a driving assembly 4 is installed on the layer plate 2, and the driving assembly 4 is equipped with several groups of placement plates 5 arranged at intervals along the extension direction of the circular guide track 3. Goods are placed on the placement plates 5 through the carrying plates so that the placement plates 5 can carry the goods and slide along the extension direction of the circular guide track 3.

[0050] Specifically, a support member 10 is fixed on the inner wall of the annular guide track 3; the driving assembly 4 includes a first driving device 401 fixed on the layer plate 2, four sprockets 402 rotating on the support member 10 and a chain 403 wound around the four sprockets 402; one of the sprockets 402 is connected to the first driving device 401 in transmission connection. After the first driving device 401 is started, it can drive one of the sprockets 402 to rotate. After that, when the sprocket 402 rotates, it can drive the remaining sprockets 402 to rotate through the chain 403 to achieve stable transmission of the chain 403.

[0051] A mounting seat is fixed to the bottom of the placement plate 5, and the mounting seat is provided with two rows of rollers 11 that can rotate and adapt to the annular guide rail 3. In this embodiment, the cross-sectional shape of the annular guide rail 3 is a convex structure, so that the roller 11 can be stuck in the annular guide rail 3. The structure and principle of the guiding sliding of this roller 11 and the annular guide rail 3 are existing technologies and will not be described in detail here. The annular guide rail 3 is located between the two rows of rollers 11, and the connecting block 12 can move along the extension direction of the annular guide rail 3 when moving with the chain 403, so as to improve the movement stability of the placement plate 5. A connecting block 12 is fixed to the bottom of the mounting seat, and the connecting block 12 is fixedly installed on the chain 403. When the chain 403 rotates, it can drive the placement plate 5 to move evenly and synchronously.

[0052] In this embodiment, the connection block 12 and the chain 403 are connected by a transition link connection, which is a prior art and will not be described in detail here.

[0053] like Figure 8 As shown, after the placement plate 5 is rotated, a positioning component 6 is fixed on the annular guide track 3. When the positioning component 6 is adapted to the placement plate 5, the feeding and discharging positions of the placement plate 5 can be limited to avoid the placement plate 5 from being offset during the picking process.

[0054] Specifically, the positioning assembly 6 includes a first telescopic device 601 hingedly connected to the annular guide track 3, a rotating rod 602 rotatably arranged on the outer surface of the annular guide track 3, a swing member 603 fixed on the rotating rod 602, and a connecting member 604 provided between the rotating rod 602 and the first telescopic device 601. After the first telescopic device 601 is started, it can drive the connecting member 604 to rotate. The lower end of the connecting member 604 is hingedly connected to the movable section of the first telescopic device 601, and the upper end of the connecting member 604 is fixed. It is mounted on the rotating rod 602. When the connecting member 604 rotates, it can drive the rotating rod 602 to rotate, so that the rotating rod 602 drives the pendulum 603 to rotate around the axis of the rotating rod 602. A limiting column 13 is fixed on the top of the pendulum 603, and a slot plate 14 adapted to the limiting column 13 is fixed on the mounting seat. When the pendulum 603 rotates, it can drive the limiting column 13 to rotate so that the limiting column 13 is stuck in the slot plate 14, thereby achieving the purpose of locking the position of the placement plate 5 and avoiding the placement plate 5 from being offset.

[0055] There are angle steels at both ends of the rotating rod 602, and the angle steels are installed on the annular guide track 3. The setting of the angle steels can support the rotating rod 602 and prevent the rotating rod 602 from falling.

[0056] like Figures 1-4 As shown, after the limiting column 13 is inserted into the slot plate 14, the placement plate 5 is locked, and then the goods can be moved into the lifting frame 7 by the traction component so that the goods can be taken.

[0057] Specifically, a lifting frame 7 is installed on the side of the fixed frame 1 facing the positioning component 6. A transfer platform 8 that can be lifted up and down is provided in the lifting frame 7. A traction component is provided on the transfer platform 8, which can move the goods placed on the placement plate 5 to the transfer platform 8.

[0058] An electric hoist mechanism 15 is fixed on the inner top wall of the lifting frame 7, and a hook plate connected to the electric hoist mechanism 15 is fixed on the transfer platform 8, so that the transfer platform 8 can be lifted up and down along the lifting frame 7. In this embodiment, the structure and principle of the electric hoist mechanism 15 are existing technologies and will not be described in detail here, so as to realize the lifting and lowering of the transfer platform 8 along the lifting frame 7, thereby driving the goods to be lifted up and down.

[0059] The traction assembly includes a rotating assembly 9 installed on the transfer platform 8 and a rotating plate 16 that is transmission-connected to the rotating assembly 9; under the action of the rotating assembly 9, the rotating plate 16 can make the goods face different directions, so that after the goods are taken off the fixed frame 1, they are lowered to the lowest end, and then the rotating plate 16 is rotated by the rotating assembly 9 to make the goods face the side away from the fixed frame 1 so that the goods can be discharged. The traction assembly also includes a telescopic assembly 17 installed on the rotating plate 16, and a box body 18 that is transmission-connected to the telescopic assembly 17 and has an upward opening. Through the telescopic assembly 17, The box body 18 can be extended into the bottom of the carrier plate where the goods are placed so that the goods can be picked up and placed. The traction assembly also includes a lifting assembly 19 installed on the bottom wall of the box body 18 and a load-bearing rod 20 installed on the lifting assembly 19. After the load-bearing rod 20 is inserted into the carrier plate, the goods are moved into the lifting frame 7 under the action of the lifting assembly 19 and the telescopic assembly 17. When the box body 18 is extended into the bottom of the carrier plate, the carrier plate can be lifted up by the lifting assembly 19 to separate the carrier plate from the placement plate 5. Then the telescopic assembly 17 contracts to pull the goods back into the lifting frame 7.

[0060] like Figures 1-4 As shown, a groove with an upward opening is provided on the top of the transfer platform 8; the rotating assembly 9 includes a second driving device 901 fixed in the groove and an auxiliary support assembly 902 fixed at the bottom of the rotating plate 16; the output end of the second driving device 901 is fixedly connected to the rotating plate 16. After the second driving device 901 is started, it can drive the rotating plate 16 to rotate to adjust the angle to facilitate the unloading and placement of goods. A guide limit groove adapted to the auxiliary support assembly 902 is provided on the top of the transfer platform 8.

[0061] In this embodiment, the auxiliary support assembly 902 includes a vertical rod fixed to the bottom of the rotating plate 16, and a sliding wheel is rotatably sleeved on the vertical rod. The vertical rod and the sliding wheel are located in a guide limit groove. When the rotating plate 16 rotates, it can drive the vertical rod and the sliding wheel to move along the guide limit groove to improve the supporting effect on the rotating plate 16.

[0062] like Figures 1-4 As shown, the telescopic assembly 17 includes a third driving device 1701 fixed on the rotating plate 16, a screw fixedly connected to the third driving device 1701, a movable plate 1702 adapted to the screw thread and a light rod inserted on the movable plate 1702. After the third driving device 1701 is started, it can drive the screw to rotate, and the movable plate 1702 is fixed to the bottom of the box 18; a transparent through hole is opened on the movable plate 1702 for the light rod to pass through. When the screw rotates, it can drive the movable plate 1702 and the box 18 to move along the extension direction of the light rod, and stop when the box 18 extends into the bottom of the carrying plate.

[0063] The lifting assembly 19 includes a scissors-type telescopic frame 1901 arranged in the box body 18 and a second telescopic device 1902 that is transmission-connected to the scissors-type telescopic frame 1901. When the second telescopic device 1902 is activated, the scissors-type telescopic frame 1901 can be expanded and contracted to support the carrying plate through the load-bearing rod 20. The scissors-type telescopic frame 1901 and the second telescopic device 1902 adopt a telescopic platform frame. The structure and principle of the telescopic platform frame are existing technologies and will not be described in detail here. The load-bearing rod 20 is fixed on the scissors-type telescopic frame 1901.

[0064] like Figures 1-4 As shown, the operator can remotely determine the required goods, and then the controller can control the first drive device 401 to start, so that the placement plate 5 corresponding to the goods moves to the positioning component 6, and then the placement plate 5 is positioned by the positioning component 6 so that the traction component can pick up and place the goods.

[0065] Specifically, a photoelectric sensor 21 is installed on the mounting seat, and a shading plate 22 is installed on the angle steel. When the shading plate 22 and the photoelectric sensor 21 are triggered, the corresponding placement plate 5 stops rotating. In this embodiment, the principle and structure of the photoelectric sensor 21 and the shading plate 22 are existing technologies and will not be described in detail here.

[0066] In this embodiment, the photoelectric sensor 21 is a slot-type photoelectric sensor. The structure and principle of the slot-type photoelectric sensor are prior art and will not be described in detail here.

[0067] Working principle: When goods need to be placed, the operator remotely operates the placement plate 5 without goods, and then the first drive device 401 starts, which can drive one of the sprockets 402 to rotate. Then, when the sprocket 402 rotates, it can drive the remaining sprockets 402 to rotate through the chain 403 to achieve stable transmission of the chain 403. When the chain 403 rotates, it can drive the placement plate 5 to move evenly and synchronously. When the photoelectric sensor 21 and the light-shielding sheet 22 on the corresponding placement plate 5 are triggered, the first drive device 401 stops. At this time, the first telescopic device 601 starts, driving the connecting member 604 to rotate. When the connecting member 604 rotates, it can drive the rotating rod 602 to rotate, so that the rotating rod 602 drives the pendulum 603 to rotate around the axis of the rotating rod 602. When the pendulum 603 rotates, it can drive the limit column 13 to rotate, so that the limit column 13 is stuck. In the slot plate 14, the placement plate 5 is locked in position, and then the electric hoist mechanism 15 suspends the transfer platform 8, so that the transfer platform 8 rises to be flush with the placement plate 5 where the goods are to be placed and then stops (an infrared receiver is provided on the transfer platform 8, and an infrared generator is installed on the layer plate 2 of each layer, so that the transfer platform 8 stops when it rises to the layer plate 2 to be placed. The structure and principle of the infrared receiver and the infrared generator are existing technologies and will not be described in detail here). The third drive device 1701 is started to drive the screw to rotate. When the screw rotates, it can drive the movable plate 1702 and the box body 18 to move along the extension direction of the light rod. When the box body 18 extends into the top of the placement plate 5, it stops. The second telescopic device 1902 is started to shrink the scissor-type telescopic frame 1901 to place the goods and the load-bearing plate on the placement plate 5 to realize the placement of the goods.

[0068] When the goods need to be taken, the above operation is repeated to move the goods into the lifting frame 7. Then, under the action of the electric hoist mechanism 15, the goods are lowered to the lowest end. Then, the second drive device 901 is started and the rotating plate 16 rotates to adjust the angle to facilitate the discharge of the goods.

[0069] The embodiments of the present invention described above do not limit the scope of protection of the present invention. The basic concept of the present invention is that by placing fixed frames 1 next to each other, no space is required for the transfer cart to move, thereby reducing space waste and improving space utilization. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
