Description

Technical Field

[0001] The present invention mainly relates to the technical field of intelligent material handling, and specifically to a smart material warehousing equipment and a comprehensive management and control platform thereof. Background Art

[0002] The current information-based social environment requires that logistics must provide material support to the demand units in a timely, appropriate place and appropriate quantity, that is, to provide the appropriate quantity of materials to the demand units at the right time and place. This puts higher demands on the speed, mobility and accuracy of logistics support.

[0003] In the past, warehouses mostly relied on primitive manual labor to carry out the storage and inventory of materials, which was a great waste of manpower and material resources, and human errors were inevitable in the manual management process. With the rapid development of artificial intelligence technology, automation technology and information technology, the intelligence level of terminal logistics is also constantly improving, and intelligent warehousing is an important part of the logistics process. In intelligent warehousing, handling robots are the main equipment that can realize automated handling operations. Handling robots can be equipped with different end effectors to complete the handling of workpieces of various shapes and states, greatly reducing the heavy physical labor of humans.

[0004] Most of the existing box handling robots use double columns as lifting guides, and use chains or belts to pull the fork up and down to pick up and put goods from the shelves. In the warehouse, the boxes are large and small, and the existing box handling robots can only handle boxes of the same size. Therefore, whether it is a small warehouse or a large warehouse, as long as there are multiple boxes of different sizes at the same time, multiple box handling robots with different configurations are required, which greatly increases the cost.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) When the multi-layer material box robot of the present invention needs to carry a larger material box, the hydraulic pump drives the lifting hydraulic rod to rise. When the lifting hydraulic rod rises, it will drive the rack to move, and the rack drives the rotating gear to rotate, so that the rotating shaft follows the rotating gear to rotate. The rotating shaft drives each sleeve rod to rotate through the sprocket and chain, so that the hydraulic screw pushes the piston to move inside the oil cylinder, and squeezes the oil inside the oil cylinder into the supporting hydraulic rod, so that each supporting hydraulic rod becomes higher synchronously, and the distance between each support plate becomes larger synchronously. When the sleeve rod rotates, the driving shaft rotates with the sleeve rod and drives the driving sprocket to rotate, so that the follower sprocket rotates. Because an extended telescopic rod is also connected between the support rod and the fixed frame, the vertical telescopic frame rods on both sides begin to move to both sides, so that each support plate has a larger material feeding space, ensuring that a larger material box can be placed on each support plate. The multi-layer material box robot has good adjustability and adaptability, can be used for the transportation of material boxes of different sizes, and can adjust itself without manual intervention, which is more convenient to use.

[0023] (2) When the multi-layer material box robot of the present invention needs to carry a larger material box, the extension screw will continuously move toward the outside of the support rod, and at the same time drive the moving block to move, so that the slider slides inside the inclined groove. The sliding of the slider will cause each protective telescopic rod to move and extend. The protective telescopic rod can change with the change of the lifting device. When carrying a large material box, the protective telescopic rod moves away from the support rod and extends. When carrying a small material box, the protective telescopic rod moves close to the support rod and shortens. This ensures that the protective telescopic rod is always in a relatively good state to protect the material box, effectively preventing the material box on the pallet from slipping.

[0024] (3) When the multi-layer container robot of the present invention needs to carry a larger container, it will simultaneously drive the two expansion bases to move, so that the center of gravity of the multi-layer container robot is lowered, thereby avoiding the possibility that the multi-layer container robot body shakes significantly when walking and picking up and placing goods as the multi-layer container robot becomes taller, thereby reducing the speed and accuracy of operation and storage and retrieval;

[0025] (4) The procurement unit of the present invention combines the material procurement plan reporting system and the balanced inventory technology, imports the procurement plan template and compares it with the existing inventory materials, and issues early warning for excessive inventory materials, so that purchasers can reduce repeated purchases of such materials, realize internal material adjustments and use between multiple warehouses, and reduce capital backlogs; the present invention realizes closed-loop management of the entire process of materials from procurement planning, contract signing, material acceptance, warehousing, outbound delivery, and waste materials.

[0042] Please see attached picture Figure 1 , a smart material warehousing equipment, including a multi-layer material box robot, the multi-layer material box robot is composed of a walking device 1, a lifting device 2 and a fork holding device 3; the multi-layer material box robot is an existing mature technology, and specific reference may be made to the HaiPick A42T telescopic lifting material box robot developed by Hai Robotics, and also to the patent application with application number 202123085154.X. This application focuses on the adjustability improvement of the multi-layer material box robot. Therefore, this application will no longer elaborate on the specific structure of the walking device 1 and the fork holding device 3.

[0043] Please see attached picture Figure 1 The walking device 1 includes an AGV body 101 and expansion bases 102 arranged on both sides of the AGV body 101. Universal wheels are installed at the bottom of the expansion bases 102, and the two expansion bases 102 are connected to the AGV body 101 through telescopic rods. When the multi-layer container robot needs to carry a larger container, it will simultaneously drive the two expansion bases 102 to move, so that the center of gravity of the multi-layer container robot is lowered, avoiding the possibility that the multi-layer container robot shakes significantly when walking and picking up and placing goods as the multi-layer container robot becomes taller, thereby reducing the speed and accuracy of operation and storage and retrieval.

[0044] Please see attached picture Figure 1 - Figure 5 The lifting device 2 includes two vertical telescopic racks 201, and a retractable cover plate 202 is installed on the upper end of the two vertical telescopic racks 201. A plurality of supporting rods 203 are arranged between the two vertical telescopic racks 201, and a supporting plate 204 is installed on each supporting rod 203. The upper and lower ends of the lifting hydraulic rod 205 are respectively connected to the expansion base 102 and the cover plate 202, and the lifting hydraulic rod 205 is driven by a hydraulic pump.

[0045] Each vertical telescopic frame rod 201 is provided with a lifting hydraulic rod 205, a vertical plate 210 and a plurality of supporting hydraulic rods 206 connected in sequence. The plurality of supporting hydraulic rods 206 are arranged vertically, and the upper end of the topmost supporting hydraulic rod 206 is connected to the cover plate 202. A fixing frame 207 is installed at the top of the extension of each supporting hydraulic rod 206, and an expansion screw 208 is rotatably installed on each fixing frame 207. The supporting rod 203 is located between the two opposite fixing frames 207. A thread groove is provided in the supporting rod 203 and is threadedly connected to the expansion screw 208 through the thread groove. An expansion telescopic rod 209 is also connected between the supporting rod 203 and the fixing frame 207; a plurality of oil cylinders 211 are installed on one side of the vertical plate 210, and the plurality of oil cylinders 211 and the plurality of supporting hydraulic rods 206 are opposite to each other, and the output end of the oil cylinder 211 and the supporting hydraulic rod 2 06, an oil pipe 212 is connected between the input ends, and a sleeve rod 213 is provided above each oil cylinder 211. The sleeve rod 213 is rotatably connected to a first bracket 214, and the first bracket 214 is installed on the vertical plate 210. The sleeve rod 213 is threadedly connected to a hydraulic screw 215, and the other end of the hydraulic screw 215 is connected to a piston, and the piston slides inside the oil cylinder 211; a second bracket 216 is provided on the other side of the vertical plate 210, and a rotating shaft 217 is rotatably installed inside the second bracket 216. The rotating shaft 217 and a plurality of sleeve rods 213 are connected by sprocket and chain transmission. A vertical rack 218 is installed on the extended end of the lifting hydraulic rod 205, and a rotating gear 219 rotatably installed on the second bracket 216 is meshed on one side of the rack 218. The rotating gear 219 is connected to the rotating shaft 217 through a plurality of bevel gears and plane gears. A third bracket 220 is installed on the first bracket 214, and a driving shaft is rotatably installed on the third bracket 220. A driving sprocket 221 is installed on one end of the driving shaft, and the other end of the driving shaft is connected to the sleeve rod 213 through mutually meshing bevel gears. A follower sprocket 222 is rotatably installed on one side of the fixed frame 207. The follower sprocket 222 is axially connected to the expansion screw 208, and the follower sprocket 222 and the driving sprocket 221 are connected through a chain transmission.

[0046] When the multi-layer material box robot needs to carry a larger material box, the hydraulic pump drives the lifting hydraulic rod 205 to rise. When the lifting hydraulic rod 205 rises, it will drive the rack 218 to move. The rack 218 drives the rotating gear 219 to rotate, so that the rotating shaft 217 rotates with the rotating gear 219. The rotating shaft 217 drives each sleeve rod 213 to rotate through the sprocket and chain, so that the hydraulic screw 215 pushes the piston to move inside the oil cylinder 211, and squeezes the oil inside the oil cylinder 211 into the supporting hydraulic rod 206, so that each supporting hydraulic rod 206 becomes higher synchronously, and the distance between each pallet 204 is synchronized. The driving shaft rotates along with the sleeve rod 213 and drives the driving sprocket 221 to rotate, so that the follower sprocket 222 rotates. Because the extension telescopic rod 209 is also connected between the support rod 203 and the fixed frame 207, the vertical telescopic frame rods 201 on both sides begin to move to both sides, so that each support plate 204 has a larger feeding space, ensuring that a larger material box can be placed on each support plate 204, so that the multi-layer material box robot has good adjustability and adaptability, can be used for the transportation of material boxes of different sizes, and can adjust itself without manual intervention, so it is more convenient to use.

[0047] Please see attached picture Figure 1 - Figure 6 Two connected inclined grooves 223 are provided at the bottom of the support plate 204, and a slider 224 slides inside each inclined groove 223. An opening is provided on one side of the threaded groove of the support rod 203. The end of the extension screw 208 is rotatably connected to a moving block 225 extending outside the threaded groove of the support rod 203. The slider 224 and the moving block 225 are connected by a telescopic rod. The other three sides of the support plate 204 are respectively provided with protective telescopic rods 226. Adjacent protective telescopic rods 226 are connected by right-angle rods. The slider 224 and the protective telescopic rod 226 are connected by a connecting rod, and the connecting rod and the protective telescopic rod 226 are slidably connected. When the multi-layer material box robot needs to carry a larger material box, the extension screw 208 will continue to move toward the outside of the support rod 203, and at the same time drive the moving block 225 to move, so that the slider 224 slides inside the inclined groove 223. The sliding of the slider 224 will cause each protective telescopic rod 226 to move and extend. The protective telescopic rod 226 can change with the change of the lifting device 2. When carrying a large material box, the protective telescopic rod 226 moves away from the support rod 203 and extends. When carrying a small material box, the protective telescopic rod 226 approaches the support rod 203 and shortens, so that the protection of the material box by the protective telescopic rod 226 is always in a relatively good state, effectively preventing the material box on the pallet 204 from slipping.

[0048] Please see attached picture Figure 1 - Figure 8Two upper wheels 227 and a driving motor are provided inside the cover plate 202, and the two upper wheels 227 are connected by a telescopic rod transmission, and the driving motor drives the telescopic rod to rotate. Lower wheels 228 are respectively provided inside the two expansion bases 102, and the two lower wheels 228 are connected by a telescopic rod transmission, and the telescopic rod runs through the AGV body 101. A conveyor belt 229 is connected between the upper wheel 227 and the lower wheel 228. Breaks are respectively provided on both sides of the conveyor belt 229, one of which connects the conveyor belt 229 through a placement plate 230, and the fork device 3 is connected to the placement plate 230. A reel 231 for winding the conveyor belt 229 is provided at the other break, one end of the conveyor belt 229 is connected to the outside of the reel 231, and the other end is coiled in the reel 231 through a coil spring. An electric push rod 232 is provided at the belt outlet of the reel 231, and a belt pressing plate 233 facing the conveyor belt 229 is installed on the electric push rod 232. When the multi-layer material box robot needs to change to adapt to material boxes of different sizes, the electric push rod 232 extends to separate the belt pressing plate 233 and the conveyor belt 229. At this time, the conveyor belt 229 inside the reel 231 can be stretched or contracted at will to avoid affecting the self-adjustment of the multi-layer material box robot. After the adjustment is completed, it is only necessary to reset the electric push rod 232 to allow the belt pressing plate 233 to press tightly against the conveyor belt 229.

[0049] Specific steps:

[0050] When the multi-layer material box robot needs to carry a larger material box, the electric push rod 232 is first started, and the electric push rod 232 extends to separate the belt pressing plate 233 and the conveyor belt 229. At this time, the conveyor belt 229 inside the reel 231 can be stretched or contracted at will;

[0051] The hydraulic pump drives the lifting hydraulic rod 205 to rise. When the lifting hydraulic rod 205 rises, it drives the rack 218 to move. The rack 218 drives the rotating gear 219 to rotate, so that the rotating shaft 217 rotates with the rotating gear 219. The rotating shaft 217 drives each sleeve rod 213 to rotate through the sprocket and the chain, so that the hydraulic screw 215 pushes the piston to move inside the oil cylinder 211, and squeezes the oil inside the oil cylinder 211 into the supporting hydraulic rod 206, so that each supporting hydraulic rod 206 is synchronously raised, so that each pallet 20 4 is synchronously enlarged. When the sleeve rod 213 rotates, the driving shaft rotates with the sleeve rod 213 and drives the driving sprocket 221 to rotate, so that the follower sprocket 222 rotates, driving the expansion screw 208 to rotate. Since an expansion telescopic rod 209 is also connected between the support rod 203 and the fixed frame 207, and the expansion screw 208 is threadedly connected to the support rod 203, the vertical telescopic frame rods 201 on both sides begin to move to both sides, so that each support plate 204 has a larger feeding space, ensuring that each support plate 204 can be placed on a larger material box;

[0052] When the extension screw 208 rotates, the extension screw 208 will continuously move toward the outside of the support rod 203, and at the same time drive the moving block 225 to move, so that the slider 224 slides inside the inclined groove 223. The sliding of the slider 224 will cause each protective telescopic rod 226 to move and extend. The protective telescopic rod 226 can change with the change of the lifting device 2, effectively preventing the material box on the support plate 204 from sliding off;

[0053] After the adjustment is completed, it is only necessary to reset the electric push rod 232 so that the belt pressing plate 233 is tightly pressed against the conveyor belt 229 .

[0054] A smart material comprehensive management and control platform adopts a smart material storage device, including an intranet system, a procurement unit and an in-and-out storage unit, and the procurement unit and the in-and-out storage unit are connected to the intranet system;

[0055] The procurement unit includes the procurement demand plan template, the balance profit module and the contract import template. The procurement unit compares the existing inventory materials through the procurement plan template, implements procurement after completing the balance profit adjustment, and imports the completed procurement contract into the material management system;

[0056] The warehousing and out-of-warehouse unit includes an acceptance module, a coding module, an entry module, and an out-of-warehouse module. The acceptance module is used to upload relevant material photos, videos, and acceptance forms to the system so that the functional departments can view them remotely. The coding module is used to scan the materials into the warehouse through a handheld PDA. If the warehouse does not have the material label, the label must be reprinted. The entry module is used to use a multi-layer material box robot to deliver the materials to the designated area. The out-of-warehouse module is used to scan the code for out-of-warehouse, and at the same time return the corresponding replaced waste materials to the waste material warehouse.

[0057] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
