Description

Technical Field

[0001] The present invention relates to the technical field of storage racks, and specifically to an intelligent logistics storage rack. Background Art

[0002] Storage racks are storage devices. More and more industries and enterprises are using storage racks, and more and more enterprises have entered the storage industry. Storage racks are one of the main facilities in warehousing and an essential part of modern industrial warehouses, logistics centers, and distribution centers. However, the existing storage racks have a single function and a simple structure.

[0003] The Chinese patent discloses "an intelligent logistics storage rack system", with the application publication number CN117963389A. The present invention includes a rack unit and a storage trolley; there are multiple layers of transmission tracks inside the rack unit; there is also a lifting unit at the end of the rack unit that can move to each layer of the transmission track; on both sides of the upper end of the storage trolley, there are loading platforms located inside the transmission ports. In the present invention, the storage trolley is used to transfer goods to each layer of the storage platform of the rack unit or the storage trolley is used to unload the goods on each layer of the storage platform from the rack unit to achieve loading and unloading; when the loading platform is higher than the storage platform, the goods on the loading platform can be moved to the corresponding position of the storage platform under the drive of the storage trolley. After the transportation is in place, the lifting column is pushed down by the push rod to make the loading platform lower than the storage platform, and the transported goods can be stably placed on the storage platform to achieve loading. Using this system for logistics storage and transportation has a higher degree of automation and realizes intelligent warehousing logistics; the Chinese patent discloses "a forklift for logistics warehousing, working method, and logistics warehousing system", with the application publication number CN119038454A. This invention discloses a forklift for logistics warehousing, working method, and logistics warehousing system. The forklift for logistics warehousing includes a moving base, on which there is a fork support and a lifting mechanism for driving the fork support to lift and lower. The fork support is provided with a fork assembly and a first driving mechanism for driving the fork assembly to extend / retract forward from the fork support. The fork assembly includes two forks arranged side by side. There is a support wheel on the front side of the bottom of the fork, and a second driving mechanism for driving the support wheel to lift and lower is provided on the fork. When handling the goods on the rack in the present invention, the fork is supported by the support wheel contacting the rack, thereby avoiding the forklift from tipping over due to the forward shift of the center of gravity, reducing the stress on the column, avoiding the bending deformation of the column, and eliminating the need to set a counterweight, reducing costs.

[0004] The above patent uses a storage cart or a forklift to transfer goods. When laying out the shelves, sufficient operating space must be reserved for the storage cart or forklift. Each shelf must correspond to the corresponding space planned for the storage cart or forklift, which will cause a lot of space waste. Due to the existence of reserved space, the number of shelves that can be placed within a limited space is relatively small. This affects the effective utilization efficiency of 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

[0019] Preferably, a photoelectric sensor is installed on the mounting seat, and a shading sheet is installed on the angle steel. When the shading 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.

[0033] 2. In the design of the entire device, when the placement plate rotates to a specific position that corresponds to the traction component, the positioning component will automatically start. At this time, the limit column in the positioning component will accurately fit into the slot plate, thereby achieving the effect of locking the placement plate.

Avoid the placement plate from tilting or offsetting during the process of taking the goods.

[0034] 3. The load-bearing rod is inserted into the load-bearing plate where the goods are placed. Then, under the action of the lifting component, the goods placed on the placement plate are supported to separate the goods from the placement plate. Then, driven by the telescopic component, the goods begin to move smoothly in the direction of the lifting frame. Subsequently, the transfer platform starts to work driven by the electric hoist mechanism. With its powerful traction capacity, the electric hoist mechanism steadily drives the transfer platform and slowly transports the goods already in the lifting frame to the bottom. The goods are smoothly transferred from a higher position to the lower area that is easy to operate, which makes it convenient for the staff to pick up the goods on the fixed frame, greatly improving the efficiency of the entire transfer process.

DETAILED DESCRIPTION

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

[0047] like Figure 1-Figure 10 As shown, a fixed frame 1 of a logistics warehousing intelligent shelf is mainly used for placing 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 a plurality of fixed frames 1 which are spaced apart in the front-to-back direction and extend in the up-down direction. The fixed frames 1 are provided with a plurality of layer plates 2 which 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 plates 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 a plurality of placement plates 5 arranged at intervals along the extension direction of the circular guide track 3, and goods are placed on the placement plates 5 through a carrying plate 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 rotatably arranged 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, and after the first driving device 401 is started, it can drive one of the sprockets 402 to rotate, and then when the sprocket 402 rotates, it can drive the remaining sprockets 402 to rotate through the chain 403, so as to realize stable transmission of the chain 403.

[0051] A mounting seat is fixed to the bottom of the placement plate 5, and two rows of rollers 11 that can rotate and adapt to the annular guide track 3 are provided on the mounting seat. In the present embodiment, the cross-sectional shape of the annular guide track 3 is a convex structure, so that the roller 11 can be stuck in the annular guide track 3. The structure and principle of the guiding sliding of the roller 11 and the annular guide track 3 are prior art and will not be described in detail here. The annular guide track 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 track 3 when it moves 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 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 assembly 6 is fixed on the annular guide track 3. When the positioning assembly 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 taking 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 arranged 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 active 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 Figure 1-Figure 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, and 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, and the traction component 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 unloaded. 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 as to pick up and place the goods. The traction assembly also includes a lifting assembly 19 installed on the inner 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 extends 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, and then the telescopic assembly 17 contracts to pull the goods back into the lifting frame 7.

[0060] like Figure 1-Figure 4 As shown, a groove with an opening facing upward 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, and 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, and 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 at 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, the vertical rod and the sliding wheel can be driven to move along the guide limit groove to improve the supporting effect on the rotating plate 16.

[0062] like Figure 1-Figure 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 supporting 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 started, the scissors-type telescopic frame 1901 can be expanded and contracted to prop up 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, and the structure and principle of the telescopic platform frame are prior art and will not be described in detail herein. The load-bearing rod 20 is fixed on the scissors-type telescopic frame 1901.

[0064] like Figure 1-Figure 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 sheet 22 is installed on the angle steel. When the shading sheet 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 sheet 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 herein.

[0067] Working principle: when goods need to be placed, the operator remotely operates the placement board 5 without goods, and then the first driving device 401 is started, 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 board 5 to move evenly and synchronously. When the photoelectric sensor 21 and the shading sheet 22 on the corresponding placement board 5 are triggered, the first driving device 401 stops. At this time, the first telescopic device 601 is started, 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 to achieve the stop of the transfer platform 8 when it rises to the layer plate 2 to be placed. The structure and principle of the infrared receiver and the infrared generator are prior art and are not described in detail here). The third driving device 1701 is started to drive the lead screw to rotate. When the lead screw rotates, it can drive the movable plate 1702 and the box body 18 to move along the extension direction of the light rod, and stop when the box body 18 extends into the top of the placement plate 5. The second telescopic device 1902 is started to shrink the scissors-type telescopic frame 1901, and the goods and the load-bearing plate are placed on the placement plate 5 to achieve 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, and then the goods are lowered to the lowest end under the action of the electric hoist mechanism 15, and then the second drive device 901 is started and the rotating plate 16 is rotated to adjust the angle to facilitate the unloading of the goods.

[0069] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. The basic concept of the present invention is that by setting the fixed frames 1 next to each other, there is no need to leave space for the transfer vehicle 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 should be included in the protection scope of the claims of the present invention.
