Description

Technical Field

[0001] This invention relates to the field of automated warehouse technology, specifically to an automated warehouse for logistics storage. Background Technology

[0002] In the process of warehousing and storing logistics goods, automated warehouses are used. Through the multi-layer racking structure in automated warehouses, not only can the utilization rate of storage space be improved, but also intelligent and automated loading and unloading operations can be realized through vertical transportation by stacker cranes. Therefore, automated warehouses can achieve the effects of rationalizing warehouse height, automating storage and retrieval, and simplifying operation, which leads to the widespread use of automated warehouses in logistics warehousing and other fields. For example, the patent disclosed in the prior art with publication number "CN110422527B" is entitled "An Automated Three-Dimensional Warehouse." It discloses a fork extension mechanism including a fork base plate, forks, side reinforcing plates, a fork drive, sensors, and front and rear housings. The fork drive is fixed to the fork base plate. When the right conveyor belt receives goods, the fork extension mechanism detects the goods' position and grabs them. Through sensor limiting, the goods are placed in the correct position on the shelf, achieving inbound storage. The fork extension mechanism grabs goods from the shelf and places them on the left conveyor belt. Then, through a pneumatic lifting platform, the height is adjusted to transport the goods to trolleys of different heights, achieving outbound storage. Both the left and right conveyor belts achieve inbound and outbound storage. The detection and limiting by sensors achieve warehousing automation. Another example is the prior art with publication number... The patent application "CN117799986A" is entitled "An Automated Three-Dimensional Warehouse". It discloses that when it is necessary to retrieve an object from a pallet located inside a support platform, the pallet indicated by the dotted line at its edge is the pallet for the object to be retrieved. First, the first drive mechanism drives the first drive disk under the rotating platform to rotate clockwise, thereby moving the pallet for the object to be retrieved and the pallet diagonally opposite it from the second position to the first position. The other two pallets diagonally opposite each other move from the second position to the third position. Next, the second drive mechanism drives the rotating platform to rotate clockwise by 90°, causing the pallet for the object to be retrieved to rotate by 90° and move to the outside of the support platform. Finally, the first drive mechanism drives the first drive disk to rotate counterclockwise, causing the pallets in the first and third positions to move to the second position.

[0003] In the aforementioned existing automated storage and retrieval systems (AS / RS), goods are placed directly on pallets. When goods are concentrated in the center of the pallet, the local pressure far exceeds the design standard for uniform load distribution, causing the pallet to dent and deform. Furthermore, prolonged use in high-temperature, high-humidity, or corrosive environments weakens the material properties of the pallets, leading to denting and deformation even under normal loads. The inability to promptly detect this deformation results in unstable goods placement, potentially causing tilting or falling, leading to personal injury or property damage. This not only affects the lifespan of the AS / RS but also its stability in handling goods. Therefore, we propose an AS / RS for logistics warehousing to address these problems. Summary of the Invention

[0004] The purpose of this invention is to provide an automated storage and retrieval system (AS / RS) for logistics warehousing, addressing the aforementioned issues raised in the background. In existing automated storage and retrieval systems (AS / RS), goods are directly placed on pallets. When goods are concentrated in the center of the pallet, the local pressure far exceeds the design standard for uniform load distribution, causing the pallet to dent and deform. Furthermore, prolonged use in high-temperature, high-humidity, or corrosive environments weakens the material properties of the pallets, leading to denting and deformation even under normal loads. The inability to promptly detect this deformation results in unstable goods placement, potentially causing tilting or falling, leading to personal injury or property damage. This not only affects the lifespan of the AS / RS but also compromises the stability of the goods placement within the system.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated warehouse for logistics warehousing, comprising a rack body and overhead rails and ground rails respectively installed on the upper and lower sides of its front side, wherein an automatic stacker crane is connected between the left sides of the overhead rails and the ground rails, lower bearing plates are installed at equal intervals inside the rack body, and an upper bearing plate for placing goods is connected above the lower bearing plate, and a lower monitoring plate is fixed inside the rack body located below the lower bearing plate, wherein an intelligent real-time monitoring component for detecting the deformation of the lower bearing plate is installed inside the lower monitoring plate.

[0006] Preferably, the right side of the automated stacker is connected to an automated clamping mechanism for automated loading, unloading and handling of goods.

[0007] Preferably, the intelligent real-time monitoring component includes an abutting plate arranged above the middle of the lower monitoring plate, a pressure sensor is installed on the lower monitoring plate corresponding to the lower part of the abutting plate, and two vertical plates are symmetrically installed under the abutting plate. The lower part of the vertical plate is connected through the slot opened inside the lower monitoring plate. Connecting blocks are symmetrically installed inside the lower monitoring plate. A vertical rod is installed in the inner side of the vertical plate through a slot. A connecting spring is nested on the outer side of the upper part of the vertical rod. And the outer side of the lower part of the vertical rod is connected through the connecting block.

[0008] Preferably, the abutting plate is arranged in an arc shape.

[0009] Preferably, a row of self-pushing rods in a "7" - shaped structure are installed on the outer side of the vertical plate.

[0010] Preferably, a rotating rod is rotatably installed in the slot opened inside the lower monitoring plate. Vortex springs are nested on the outer sides of the front and rear ends of the rotating rod. And a rotating plate is fixedly penetrated on the outer side of the rotating rod. The rotating plate is arranged in a "V" - shaped structure. And a self - pushing rod is correspondingly arranged above one end of the rotating plate. And a pushing plate is installed on the other end of the rotating plate through a damping rotating shaft. The rotating plate forms a rotating structure through the self - pushing rod.

[0011] Preferably, inverted "T" - shaped guide rods are installed at the four corners of the bottom surface of the upper bearing plate.

[0012] Preferably, a weighing mechanism is embedded and installed at the middle position of the upper surface of the lower bearing plate. The highest point of the weighing mechanism is higher than the highest point of the lower bearing plate. And through - holes are opened at the four corners of the upper surface of the lower bearing plate. And guide rods are penetrated through the inside of the through - holes. And the upper surface of the weighing mechanism is in close contact with the bottom surface of the upper bearing plate.

[0013] Preferably, an installation groove and a diversion groove are opened on the upper surface of the upper bearing plate. And a sponge pad and a humidity sensor are installed in the installation groove in sequence from top to bottom.

[0014] Preferably, both the installation groove and the sponge pad are arranged in a "return" - shaped structure. And the diversion groove is arranged in an inclined shape. And the space inside the diversion groove is connected with the space inside the installation groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This three - dimensional warehouse for logistics storage can improve the service life of the three - dimensional warehouse, and can also improve the stability of the three - dimensional warehouse for placing goods, facilitating the three - dimensional warehouse to place the goods of logistics storage well. The specific content is as follows: (1) When the abutment plate in the intelligent real-time monitoring component is subjected to the pressure of the lower bearing plate that deforms downward, the abutment plate can automatically move downward to apply a certain pressure to the pressure sensor, thereby enabling the pressure sensor to intelligently monitor whether the lower bearing plate has deformed downward in real time, and can promptly issue early warnings for dangerous situations to prevent goods from tilting and falling, thereby improving the service life of the automated warehouse and the stability of goods placement in the automated warehouse, making it easier for the automated warehouse to place goods in logistics storage. Furthermore, by moving the self-push rod downwards via the vertical plate, the self-push rod applies a downward thrust to one end of the rotating plate, causing the rotating plate to rotate around the rotating rod as the center. This causes the push plate installed at the other end of the rotating plate to contact the bottom surface of the lower support plate and apply an upward thrust, thereby preventing the lower support plate from deforming too much downwards. Therefore, the stability of the automated warehouse for placing goods can be further improved.

[0016] (2) The weighing mechanism facilitates the detection of the weight of the lower bearing plate and the goods placed on it. The data obtained by the weighing mechanism is then analyzed by the microcontroller. This allows us to know the total weight of the goods in the left half of the shelf body, the total weight of the goods in the right half of the shelf body, the total weight of the goods in the upper half of the shelf body, and the total weight of the goods in the lower half of the shelf body. After analysis and comparison, the placement of the goods can be adjusted to avoid the situation where the left half of the shelf body is heavier and the right half is lighter, or the left half is lighter and the right half is heavier, or the upper half is heavier and the lower half is lighter. This can prevent the shelf body from deforming due to uneven stress, thus further improving the service life of the shelf body. (3) The leaked liquid can flow into the installation groove through the inclined guide channel and come into contact with the sponge pad, which will then absorb the liquid and become wet. Later, the humidity sensor can intelligently monitor the humidity of the sponge pad in real time, and can promptly know whether the liquid goods placed on the upper support plate have broken and leaked, which can meet different usage needs.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-12 The present invention provides the following technical solution: Example 1: The automated warehouse for logistics storage in this example can intelligently monitor whether the lower support plate 7 is deformed downwards by using pressure sensor 17. This eliminates the need for manual measurement by staff, allowing the entire automated warehouse to provide timely warnings of dangerous situations and improving the stability of goods placement. The specific structure is shown in the attached diagram. Figures 1-10As shown, the system includes a rack body 1 and overhead rails 6 and ground rails 4 installed on its front upper and lower sides respectively. An automatic stacker crane 5 is connected between the left sides of the overhead rails 6 and ground rails 4. Lower support plates 7 are installed at equal intervals inside the rack body 1, and an upper support plate 3 for placing goods is connected above the lower support plates 7. A lower monitoring plate 2 is fixed inside the rack body 1 below the lower support plates 7. An intelligent real-time monitoring component for detecting the deformation of the lower support plates 7 is installed inside the lower monitoring plate 2. An automatic clamping mechanism 51 for automated loading, unloading and handling of goods is connected to the right side of the automatic stacker crane 5. The intelligent real-time monitoring component includes an abutment plate 11 located above the middle of the lower monitoring plate 2, and a pressure sensor 17 is installed on the lower monitoring plate 2 corresponding to the abutment plate 11. Two vertical plates 15 are symmetrically installed below the abutment plate 11, and the lower part of the vertical plates 15 is connected to the lower monitoring plate 2. The internal slots are connected through the vertical plate 15. Connecting blocks 18 are symmetrically installed inside the lower monitoring plate 2. A vertical rod 151 is installed in the slot on the inner side of the vertical plate 15. A connecting spring 152 is nested on the upper outer side of the vertical rod 151. A connecting block 18 is connected through the lower outer side of the vertical rod 151. The abutment plate 11 is arc-shaped. A row of self-push rods 16 in a figure-7 shape is installed on the outer side of the vertical plate 15. A rotating rod 13 is rotatably installed in the slot inside the lower monitoring plate 2. A spiral spring 131 is nested on the outer side of both the front and rear ends of the rotating rod 13. A rotating plate 14 is fixed through the outer side of the rotating rod 13. The rotating plate 14 is V-shaped. A self-push rod 16 is correspondingly installed on the upper side of one end of the rotating plate 14. A push plate 12 is installed on the other end of the rotating plate 14 through a damping shaft. The rotating plate 14 forms a rotating structure through the self-push rod 16.

[0021] First, multiple rack bodies 1 and automatic stacker cranes 5 are installed in the working area, at which point the entire automated warehouse can be put into use. The automatic stacker crane 5 moves left and right between the ground rail 4 and the overhead rail 6. The automatic stacker crane 5 adopts laser navigation and vision-assisted precise positioning technology, which allows the automatic stacker crane 5, in conjunction with the automatic clamping mechanism 51, to automatically place goods on the corresponding upper bearing plate 3 and to remove goods from the corresponding upper bearing plate 3. Therefore, the entire automated warehouse can realize intelligent automated loading and unloading operations, enabling automated storage and retrieval of goods and automated inbound and outbound operations. This not only greatly reduces the input of manpower, but also improves work efficiency. Since this part is existing technology, it will not be described in detail here.

[0022] When heavy goods are concentrated in the center of the upper bearing plate 3, the local pressure will far exceed the design standard of the uniformly distributed load of the upper bearing plate 3, causing the upper bearing plate 3 to dent and deform. When the upper bearing plate 3 is used for a long time in an environment with high temperature, high humidity or corrosive substances, the material properties will be weakened, causing the upper bearing plate 3 to dent after long-term use under normal load. When the automatic stacker crane 5 collides with and frequently retrieves goods, the instantaneous impact force will far exceed the static load, causing local plastic deformation of the upper bearing plate 3 and the lower bearing plate 7. Long-term accumulation of micro-deformation will significantly reduce the upper load limit. Therefore, when the upper bearing plate 3 and the lower bearing plate 7 dent and deform downward due to the above reasons, the downward dent of the middle area of ​​the lower bearing plate 7 will contact the abutment plate 11 and apply a downward pressure to the abutment plate 11, causing the abutment plate 11 to drive the vertical plates 15 on the left and right sides to move downward together. At this time, the connecting block 18 is in The outer side of the vertical rod 151 slides, and the connecting spring 152 stores force. After the abutment plate 11 moves down to a certain height, it applies a downward pressure to the pressure sensor 17. The pressure sensor 17 then detects the pressure and transmits the signal to the microcontroller. After analysis, the microcontroller controls the alarm to sound an alarm. Thus, the pressure sensor 17 can intelligently monitor in real time whether the lower support plate 7 has undergone downward deformation. The alarm can promptly warn of dangerous situations, so that staff or automatic stacker crane 5 can come in time to remove the goods, preventing the goods from tilting and falling. This can improve the service life of the entire automated warehouse and also improve the stability of the warehouse for placing goods. It is convenient for the automated warehouse to place goods in the logistics warehouse. There is no need for staff to regularly check whether the upper support plate 3 and the lower support plate 7 in the automated warehouse have deformed. The operation is convenient, time-saving and labor-saving.

[0023] At the same time, when the vertical plate 15 moves downward, it will drive the self-push rod 16 to move downward as well. At this time, the lower end of the self-push rod 16 applies a downward thrust to one end of the rotating plate 14, causing the rotating plate 14 to rotate around the rotating rod 13 as the center. The spiral spring 131 stores energy. At this time, the other end of the rotating plate 14 drives the horizontal push plate 12 to move upward, so that the push plate 12 contacts the bottom surface of the lower bearing plate 7 and applies an upward thrust. This can prevent the lower bearing plate 7 from sinking and deforming too much, thus further improving the stability of the automated warehouse for the placement of goods.

[0024] Example 2: The automated warehouse for logistics warehousing in this example, based on Example 1, can avoid the overall deformation of the rack body 1 due to uneven stress, thus further improving the service life of the rack body 1. The specific structure is shown in the attached diagram. Figure 4 and Figure 11As shown in the figure, inverted "T"-shaped guide rods 8 are installed at the four corners of the bottom surface of the upper bearing plate 3. A weighing mechanism 10 is embedded and installed at the middle position of the upper surface of the lower bearing plate 7, and the highest point of the weighing mechanism 10 is higher than the highest point of the lower bearing plate 7. Through holes 9 are provided at the four corners of the upper surface of the lower bearing plate 7, and the guide rods 8 penetrate through the interiors of the through holes 9. The upper surface of the weighing mechanism 10 is in close contact with the bottom surface of the upper bearing plate 3.

[0025] When goods are placed on the upper bearing plate 3 inside the entire stereoscopic warehouse, the weighing mechanism 10 installed on the upper surface of the lower bearing plate 7 can measure the weight of the upper bearing plate 3 and the weight of the goods on the upper bearing plate 3 at this time. Then, the weighing mechanism 10 transmits the weighing data to the single-chip microcomputer, and the single-chip microcomputer analyzes the data obtained by the weighing mechanism 10. Since the single-chip microcomputer is a prior art, no detailed introduction will be made here. From this, the total weight of the goods in the left half of the shelf body 1, the total weight of the goods in the right half of the shelf body 1, the total weight of the goods in the upper half of the shelf body 1, and the total weight of the goods in the lower half of the shelf body 1 can be obtained. After analysis and comparison, the placement position of the goods is adjusted by the automatic stacker 5. In this way, it can be avoided that the left half of the shelf body 1 is heavier, the right half is lighter, or the left half is lighter, the right half is heavier, or the upper half is heavier, and the lower half is lighter. In this way, it can be avoided that the shelf body 1 is deformed as a whole due to uneven force, so the service life of the shelf body 1 can be further improved.

[0026] Embodiment 3: In the logistics storage stereoscopic warehouse in this embodiment, on the basis of Embodiment 1, it is possible to intelligently and real-time monitor whether the liquid goods placed on the upper bearing plate 3 are broken and leaked, avoiding an excessive leakage amount in the later stage and increasing the cleaning workload, and meeting different usage requirements. The specific structure is referred to in Appendix Figure 4 and Appendix Figure 12 As shown in the figure, mounting grooves 19 and diversion grooves 21 are provided on the upper surface of the upper bearing plate 3. A sponge pad 22 and a humidity sensor 20 are installed in sequence from top to bottom inside the mounting groove 19. The mounting groove 19 and the sponge pad 22 are both arranged in a "hui" - shaped structure, and the diversion groove 21 is arranged in an inclined shape. The space inside the diversion groove 21 is connected to the space inside the mounting groove 19.

[0027] When the goods placed on the upper bearing plate 3 are liquid goods and the liquid goods are broken and leaked, at this time, the liquid flows into the mounting groove 19 through the inclined diversion groove 21, and the liquid in the mounting groove 19 is adsorbed by the sponge pad 22. Then, the humidity sensor 20 intelligently and real-time monitors the humidity of the sponge pad 22, and it can be timely known whether the liquid goods placed on the upper bearing plate 3 are broken and leaked, meeting different usage requirements, and thus completing a series of operations.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
