Description

Technical Field

[0001] The present invention relates to the technical field of warehousing, and in particular to an automated warehousing system and an inventory method for a warehousing system. Background Art

[0002] In recent years, with the continuous development of the logistics industry and the increasing trend of warehousing automation, intelligence, and unmanned operation, the original flat warehouses are no longer sufficient to meet the requirements of modern logistics for warehousing storage capacity, inbound and outbound speed, and reduction of enterprise cost expenditure. Many warehousing users have started to transform or directly select warehouses with higher automation levels.

[0003] The width of the aisles in the original stacking warehouses is usually about four meters, which can accommodate two straddle carriers running in parallel. However, the warehouse aisles occupy a large amount of warehousing space, reducing the utilization rate of the warehouse space. To improve the utilization rate of the warehouse space, modern warehouses have started to adopt intelligent stereoscopic shelves. The shelves are placed closely, and the aisles between the shelves are narrower because only stacker cranes can operate in them, which are called "lanes". Compared with the goods aisles in traditional warehouses, the lanes are narrower and occupy less floor area. However, due to the large number of lanes, the utilization rate of the warehouse space will also be reduced. At the same time, the stacker crane needs to move back and forth to pick up and deliver goods, resulting in low picking and storing efficiency. Summary of the Invention

[0004] Based on this, the technical problem to be solved by the present invention is to provide an automated warehousing system with high warehouse space utilization rate and high inbound and outbound efficiency.

[0050] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the following will further elaborate on the present invention in conjunction with the accompanying drawings and embodiments.

[0051] It should be noted that in the description of the present invention, the terms indicating the direction or positional relationship such as "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the direction or positional relationship shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0052] Referring to Figures 1-10 , the automated storage system of the present invention includes a shelf 100, a goods temporary storage device 200, and a goods picking and placing device.

[0053] The shelf 100 is used for storing goods. The shelf 100 includes at least one layer of shelf units 110, and the shelf units can enable the goods to rotate horizontally. Preferably, the shelf 100 includes multiple layers of shelf units 110, which is a multi-layer rotary shelf. Each layer has a shelf unit 110 that can enable the goods to rotate horizontally and can rotate independently horizontally according to actual needs. Each layer has an inlet and outlet at a fixed position.

[0054] The goods temporary storage device 200 is arranged outside the shelf 100 and includes a temporary storage table 210. The temporary storage table 210 includes a number of temporary storage units 211 arranged in a rectangular array and connected. The temporary storage units 211 can drive the goods to move between the respective temporary storage units 211. One temporary storage unit located inside the goods temporary storage table 210 is docked with the inlet and outlet of the shelf unit 110. Multiple goods output from the shelf can be temporarily stored on the temporary storage table 210.

[0055] The goods picking and placing device is arranged outside the goods temporary storage table 210 and is used for picking and placing goods from one temporary storage unit located outside the goods temporary storage table 210.

[0056] In the automated storage system of the present invention, by setting a multi-layer rotary shelf, the target goods can be output from the shelf in a timely manner. The shelf is further combined with the goods temporary storage device to cache multiple goods on the temporary storage table. Through the operation of the goods on the temporary storage table, the difference between the inbound and outbound speed of the goods at the shelf and the speed of the stacker can be buffered, the waiting time can be shortened, and the inbound and outbound efficiency can be improved.

[0057] Referring to Figures 1-10 , it is an embodiment of the automated storage system of the present invention. For the convenience of subsequent description, in this embodiment, the position descriptions of "inner side" and "outer side" are both based on the shelf 100, that is, the side facing the center of the interior of the shelf 100 is the inner side, and the side facing the outside of the shelf 100 is the outer side. The specific distribution of the automated storage system is as Figure 1As shown, it includes an inventory area E, a goods temporary storage area F, a roadway G, an AGV cart operation area H, an outbound temporary storage area I, an inbound temporary storage area J, a passage area K, etc. Shelves 100 are arranged in the inventory area E for storing goods. As Figure 2 As shown, the shelves 100 in this embodiment are of a circular shelf structure. Each layer includes shelf units 110 that can horizontally rotate the goods, and the goods move in a cycle on their respective shelf units 110. Outside the shelf unit 110, the outside of the inventory area E is the goods temporary storage area F. A goods temporary storage device 200 is arranged in the goods temporary storage area F. The shelf unit 110 outputs the target goods at the loading and unloading ports, and sequentially stores the target goods on the temporary storage platforms 210 of the goods temporary storage device 200. The outside of the goods temporary storage area F is the roadway G. A goods picking and placing device such as a stacker or a forklift travels back and forth along the roadway for picking and placing goods from the temporary storage device; the outside of the roadway G is the AGV cart operation area H, and the AGV cart transports the goods after loading to the outside outbound temporary storage area I.

[0058] In this embodiment, as Figure 2 As shown, multiple layers of shelf units 110 are arranged on the shelves 100. According to the size of the goods stored in the warehouse, preferably, each shelf 100 is divided into seven layers. The height of each layer of the shelf 100 can be freely adjusted. According to the analysis of the quantity and type of goods, the goods with heavy quality, large volume and high value are placed on the bottom layer, and the lighter the goods placed on the higher layers. Taking the bottom layer of the shelf 100 as an example, large-sized goods are placed on the bottom layer. Assuming that refrigerators are placed on this layer, and the refrigerators are divided into twenty different models. The quality and weight of each model of refrigerator are relatively close, so they can be placed on the same layer and randomly arranged. One goods is contained in one pallet to form an inventory unit. The warehouse management system records the goods data in the computer and dynamically monitors the goods area in real time. During the operation process, the background warehouse information management system retains the unique attributes of each SKU to ensure the rapid matching of the target goods on the order with the goods in the shelves and accurate positioning.

[0059] Preferably, the shelf 100 is of a cuboid shelf structure, and the cross-section of the shelf 100 is a rectangular closed-loop structure. The closed-loop is to avoid being restricted by the first-in, first-out rule and always keep the shelf unit 110 rotating at a constant speed, so that each piece of goods has an equal opportunity to reach the loading and unloading ports. A plurality of shelves 100 are arranged side by side without gaps in the width direction, and a goods temporary storage device 200 is arranged outside the end of each shelf 100. A moving device can be arranged at the bottom of the shelf 100 for easy movement. In this embodiment, by reducing the passages between the shelves 100, the number of shelves 100 can be increased to increase the inventory units, and the number of stackers can also be reduced to save costs.

[0060] The lane is located outside the goods temporary storage device 200 and is arranged along the width direction of the shelf 100 for the movement of the goods picking and placing device. The goods picking and placing device can be responsible for picking and placing goods on multiple shelves 100. The goods picking and placing device is preferably a stacker. One stacker can be responsible for multiple shelves 100. The stacker only needs to run horizontally to find the goods temporary storage device 200 where the goods to be taken in and out are located, reducing the detour route and shortening the operation time.

[0061] As Figure 4 shown, in order to pick and place goods on different-layer shelf units 110, the goods temporary storage device 200 further includes a lifting device 220. The lifting device 220 is used to drive the goods temporary storage platform 210 to move up and down between different-layer shelf units 110.

[0062] Specifically, as Figure 5 shown, the lifting device 220 includes a bracket 221 and a lifting drive mechanism arranged on the bracket 221. The bracket 221 is arranged on one side of the shelf 100. The lifting drive mechanism is connected to the goods temporary storage platform 210 to drive the goods temporary storage platform 210 to move up and down. Specifically, the lifting drive mechanism includes drive wheels 222 respectively arranged at the upper and lower ends of the bracket 221, a drive chain 223 drivingly connected to the two drive wheels 222, and a drive motor 224. The drive motor 224 is connected to one of the drive wheels 222 to drive the drive wheel 222 to rotate. In this embodiment, the drive motor 224 is arranged at the top of the bracket 221. The goods temporary storage platform 210 is fixedly connected to the drive chain 223 to achieve lifting movement through the drive chain 223.

[0063] Referring to Figure 6 and Figure 7 shown, in this embodiment, there are four temporary storage units 211 arranged in a square shape. The temporary storage unit 211 docked with the incoming and outgoing ports of the shelf unit 110 and the temporary storage unit 211 corresponding to the goods picking and placing device are located on the shortest path of the straight-line transportation of goods. As shown in the figure, the positions of the 4 temporary storage units 211 are respectively marked as Area A, Area B, Area C, and Area D in the counterclockwise order. Among them, the temporary storage unit in Area A is docked with the outgoing port of the shelf unit 110, and the temporary storage unit in Area B is docked with the incoming port of the shelf unit 110; the temporary storage unit in Area D corresponds to the picking device, and the temporary storage unit in Area C corresponds to the incoming device.

[0064] Each temporary storage unit 211 can be composed of one or more platform structures. In this embodiment, each temporary storage unit 211 is preferably composed of four separately controllable platform structures. As Figure 8As shown in the figure, specifically, the platform structure includes a platform body 211, a first conveying component, and a second conveying component. The first conveying component can move goods on the platform body 211 along a first direction x. The second conveying component can move goods on the platform body 211 along a second direction y perpendicular to the first direction.

[0065] Specifically, referring to Figure 9 and Figure 10 , the first conveying component includes a set of fixed wheels 212 protruding from the top surface of the platform body 211 and a first driving component for driving the set of fixed wheels 212 to rotate; the first direction x is perpendicular to the axis direction of the set of fixed wheels 212. The platform body 211 has an internal cavity, which is a square structure. The set of fixed wheels 212 and the first driving component are arranged in the internal cavity, and a number of slot holes are opened on the top surface of the platform body 211 to allow the set of fixed wheels 212 to protrude.

[0066] Specifically, the set of fixed wheels 212 includes a plurality of fixed wheels 212 arranged coaxially and at intervals, and there are several rows of coaxially arranged fixed wheels 212. The first driving component includes a first motor 213, a first connecting rod 214, and a first connecting mechanism. The coaxially arranged fixed wheels 212 are connected in series and fixed by the first connecting rod 214, and both ends of the first connecting rod 214 are rotatably arranged on the platform body 211. The first motor 213 drives the first connecting rod 214 to rotate around its axis through the first connecting mechanism. The first connecting mechanism includes a first transmission wheel 215 connected to the output shaft of the first motor 213, a second transmission wheel 216 sleeved and fixed on the first connecting rod 214, and a first transmission belt 217.

[0067] The second conveying component includes a set of lifting wheels 212, a second driving component for driving the set of lifting wheels 212 to rotate, a substrate 2192, and a third driving component. The axis of the set of lifting wheels 212 is perpendicular to the axis of the set of fixed wheels 212. The set of lifting wheels 212 is arranged on the substrate 2192, and the third driving component drives the substrate 2192 to lift, so that the set of lifting wheels 212 is higher or lower than the set of fixed wheels 212, forming a height difference with the set of fixed wheels 212.

[0068] The set of lifting wheels 212 includes a plurality of lifting wheels 212 arranged coaxially and at intervals, and bearing seats 2191 for installing the lifting wheels 212. The bearing seats 2191 are fixed on the substrate 2192, and the lifting wheels 212 are rotatably arranged on the bearing seats 2191. There are several rows of coaxially arranged lifting wheels 212, which are arranged in a grid-like staggered manner with the fixed wheels 212.

[0069] The second driving component includes a second motor 213, a second connecting rod 214, a second connecting mechanism, and a third connecting mechanism. Coaxial bearing seats 2191 are connected in series through the second connecting rod 214. The second motor 213 drives the second connecting rod 214 to rotate around its axis through the second connecting mechanism, and the second connecting rod 214 drives the lifting wheel 212 to rotate through the third connecting mechanism.

[0070] The second connecting mechanism includes a third transmission wheel 215 connected to the output shaft of the second motor 213, a fourth transmission wheel 216 sleeved and fixed on the second connecting rod 214, and a second transmission belt 217.

[0071] The third connecting mechanism includes a first gear 2181 sleeved and fixed on the axle of the lifting wheel 212 and a second gear 2182 sleeved and fixed on the second connecting rod 214.

[0072] The third driving component is preferably a driving cylinder (not shown). The driving cylinder is connected to the substrate 2192 and is used to drive the substrate 2192 to move up and down, thereby driving the lifting wheel 212 group to move up and down.

[0073] The working principle of the temporary storage unit 211 is as follows: The height position of the fixed wheel 212 relative to the platform body 211 remains unchanged, and its rotation is realized by driving of the first motor 213. The lifting wheel 212 group can move up and down relative to the platform body 211 through the driving cylinder, and its rotation is realized by the second motor 213. When the lifting wheel 212 group descends and the top of its wheel rim is lower than the top of the wheel rim of the fixed wheel 212 group, the goods can move along the first direction x driven by the fixed wheel 212. When the lifting wheel 212 rises higher than the fixed wheel 212, the goods can move along the second direction y driven by the lifting wheel 212. In this embodiment, exemplarily, the lateral direction is the first direction x, and the fixed wheel 212 group drives the goods to move in the lateral direction; the longitudinal direction is the second direction y. After the lifting wheel 212 group rises, it drives the goods to move in the longitudinal direction.

[0074] In this embodiment, the shelf unit 110 includes a frame, a conveying component and a steering component 112 disposed on the frame. The target goods are transferred from the shelf unit 110 through the steering component 112 provided on the shelf unit 110. The steering component 112 can change the direction of the goods and convey the goods to the temporary storage table 210. In this embodiment, the steering component 112 preferably adopts the same structure as the temporary storage unit 211. By setting the steering component 112 at the turning point of the shelf unit 110 as the goods screening area, not only can the goods be steered during the turning process on the shelf unit 110, but also the target goods can be controlled to be transferred out to the temporary storage table 210. The moving state of the goods during this process is translation, and the orientation of the goods remains unchanged. In this embodiment, the conveying component includes a plurality of rollers 111 laid on the frame and a gear chain mechanism for driving the rollers 111 to roll. In other embodiments, the steering component 112 can be a pushing structure such as a push rod, and the conveying component can be a conveyor belt structure.

[0075] The working principle of the temporary storage table 210 is as follows: Figure 7 As shown in the figure, when the outbound operation is running, the target goods enter the temporary storage table 210 through the steering component 112, first enter the temporary storage unit in area A, and then move to area D, where the stacker picks up the goods. If there are still goods in area D at this time, the goods will move to area B and then to area C. When the goods in area D have been picked up and there are no goods in area A, the goods in area C are replenished to area D for the stacker to pick up, so as to maintain continuous operation as much as possible.

[0076] During the process that the target goods enter area A in sequence, move to area D finally, and finally leave the shelf 100, the number of goods retained by the temporary storage table 210 is not fixed, and the capacity that can be accommodated in different layers is different. For example, when picking up the goods on the bottom layer, at most 4 goods can be accommodated, and the occupied position is shown as the shaded part in area A in the figure; when picking up the goods on the middle four layers, at most 16 goods can be accommodated, and the occupied size of each good is shown as the shaded part in area B in the figure; when picking up the goods on the top two layers, at most 64 goods can be accommodated, and the occupied size of each good is shown as the shaded part in area C in the figure.

[0077] The shelf 100 can ensure the orderly movement of the goods through the background design algorithm. At this time, it is necessary to simulate and match the picking speed of the stacker to ensure that the temporary storage table 210 is not overloaded with goods during a batch picking operation, so as to ensure a high inbound and outbound efficiency.

[0078] The working process of the goods inbound and outbound is as follows:

[0079] When the warehousing system receives an order, the order task is allocated to a specific shelf unit 110 through algorithm calculation by background control. When the target goods move to the area of the steering component 112, the steering component 112 adjusts to quickly change the direction of the target goods, so that the target goods enter the temporary storage table 210. After that, the steering component 112 resumes its original direction to ensure the normal circular operation of the remaining goods. The replenishment process is the opposite. Whether it is inbound replenishment or outbound picking, the location of the target goods is completely fixed, adopting the mode of "stock keeping unit looking for the machine", which can avoid the path repetition caused by the stacker looking for the stock keeping unit and greatly improve the inbound and outbound efficiency.

[0080] Specifically, the operation rules for goods inbound and outbound are as follows:

[0081] As Figure 3 shown, when the outbound instruction is issued, both the temporary storage table 210 and the shelf 100 enter the outbound preparation state, that is: first, the target goods are transported from the b area of the shelf unit 110 to the temporary storage unit 211 in area A. At this time, 2 paths are separated. ① Direct outbound: When directly outbound, the goods are directly transported from area A to area D. At this time, the fork of the stacker waits in front of area D to receive the goods. ② Temporary storage waiting for outbound: In many cases on the same layer, there are multiple outbound requirements for goods. The stacker needs to take out the goods one by one, which requires repeated operation time. The goods can enter the temporary storage table 210 to leave a buffer time for the stacker operation and ensure the continuous operation of the shelf 100. When there are goods to be picked in area D, area A adjusts, transfers the goods in area A to area B, and area B then transports the goods to area C. When there is a vacancy in area D, area C then transports the goods into area D to wait for outbound. The stacker takes down the target. During the whole process, the shelf unit 110 rotates at a constant speed without change, and then the stacker puts the goods on the AGV cart and transports them to the outbound temporary storage area to complete the outbound operation.

[0082] When the inbound instruction is issued, both the temporary storage table 210 and the shelf 100 enter the inbound preparation state, that is: the stacker places the goods on Figure 5 the C area of the temporary storage table 210 as shown. Area C transports the goods from area C to area B, area B then transports the goods to the a area of the shelf, and area a further moves the goods into the shelf 100 to achieve inbound.

[0083] The present invention also includes an inventory method for a warehousing system. As Figure 11 shown, the inventory method specifically includes:

[0084] S100, receiving an outbound task, and sequentially inputting the target goods onto the temporary storage unit at the entrance of the temporary storage table according to the outbound order;

[0085] S200, judging whether there are target goods in the temporary storage unit at the exit;

[0086] For S300, if it is determined that there is no goods, the target goods will be linearly conveyed to the temporary storage unit at the exit; if it is determined that there is goods, the target goods on the temporary storage unit at the entrance will be conveyed to other temporary storage units, and the target goods will be transported through the temporary storage units and sequentially transported to the temporary storage unit at the exit according to the outbound order.

[0087] The warehouse management system can ensure the orderly movement of goods through the background design algorithm. The temporary storage unit at the exit on the temporary storage platform is taken down by the loading and unloading device. The warehouse management system controls the outbound quantity of the shelf unit according to the picking speed of the matching stacker to ensure that the temporary storage platform is not overloaded with goods during a batch picking, so as to ensure a high inbound and outbound efficiency.

[0088] The inventory method of the above-mentioned warehousing system can buffer the difference between the inbound and outbound speed of goods at the shelf and the stacker speed through the operation of goods on the temporary storage platform, shorten the waiting time, and improve the inbound and outbound efficiency.
