Description
Technical Field
[0001] The utility model belongs to the technical field of transportation and storage, and specifically relates to a cargo transfer device suitable for intelligent warehousing. Background Art
[0002] Three-dimensional warehousing, also known as three-dimensional warehouse, is a new concept in logistics warehousing. It uses three-dimensional warehouse equipment to achieve high-level rationalization of warehouses and automatic storage and retrieval. It has the following advantages: 1. High-level shelf storage; 2. Automatic storage and retrieval; 3. Computer control; 4. Used in conjunction with other conveying equipment to better link the warehouse and the workshop.
[0003] At present, the commonly used three-dimensional warehousing system includes a three-dimensional storage rack, a cargo transfer device, an AGV transfer vehicle and a central control device. Under the control of the central control device, the AGV transfer vehicle takes out the cargo from the cargo transfer unit and moves to the corresponding storage position of the three-dimensional storage rack to complete intelligent warehousing.
[0004] However, as a cargo transfer, it generally plays a role similar to a transfer station, and its own role has no connection with subsequent warehousing. Therefore, it has the following defects:
[0005] 1) It not only greatly increases the difficulty of later warehousing, but also is not conducive to the planning of cargo storage routes;
[0006] 2) The center of gravity of the cargo cannot be effectively assessed. Therefore, during transshipment, the unstable center of gravity will increase the safety hazard of cargo collapse and accidental falling. Summary of the invention
[0007] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an improved cargo transfer device suitable for intelligent warehousing.
[0008] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0009] A cargo transfer device suitable for intelligent warehousing includes a frame and a frame forming a transfer station. The cargo transfer device also includes a floor scale arranged in the frame and constituting the bottom of the transfer station, an information processor installed on the frame and based on vision or three-dimensional scanning to obtain XYZ axis coordinates and shape information of the cargo, and an alarm connected to the information processor, wherein the information processor estimates the position of the center of gravity based on the acquired shape, and if the center of gravity is not on the center line of the transfer station, the alarm will sound an alarm.
[0010] Preferably, the stand comprises a frame plate fixedly mounted on opposite sides of the scale, wherein the frame plate is located above the side of the scale and connected to the frame, so as to avoid interference between the scale and the frame plate.
[0011] Furthermore, the shelves on both sides are symmetrically arranged with respect to the direction of entering and exiting the transfer station.
[0012] According to a specific implementation and preferred aspect of the utility model, each shelf includes a straight plate extending along the direction of entering and exiting the transfer station, and folding plates located at both ends of the straight plate and tilted outward, the two straight plates and the floor scale constitute the transfer station, and a receiving bell mouth for entering and exiting the transfer station is formed between the two folding plates located at the same end. Based on the setting of the receiving bell mouth, it is more convenient for pallets and goods to enter and exit the transfer station.
[0013] According to another specific implementation and preferred aspect of the utility model, the length of the straight board is equal to the length of the pallet; the distance between the straight boards is greater than the width of the pallet, wherein the inner wall of each straight board is installed with a ball assembly that can form a rolling guide contact with the side of the pallet. Based on the guidance formed by the ball assembly, the pallet can enter and exit the transfer station more smoothly, so that the center of gravity of the goods can be estimated more accurately, that is, to provide safety assistance for later transfer and storage.
[0014] Preferably, the ball assembly includes a ball seat and a universal ball exposed from a side surface of the ball seat to form rolling spherical contact.
[0015] Furthermore, there are at least two ball assemblies on each straight plate, and they are distributed at intervals.
[0016] In addition, the information processor uses a visual camera to obtain information; or, the information processor uses a profile scanner to obtain a 3D shape of the cargo.
[0017] Preferably, the frame includes a plurality of racks extending along the XYZ axes and butted against each other, wherein the vision cameras or the profile scanners are mounted on the racks.
[0018] Due to the implementation of the above technical solution, the utility model has the following advantages compared with the prior art:
[0019] In the existing warehousing process, cargo transfer generally plays a role similar to a transfer station, and its own role has no connection with the subsequent warehousing. Therefore, it not only greatly increases the difficulty of later warehousing, but also is not conducive to the planning of cargo storage routes. At the same time, the center of gravity of the cargo cannot be effectively evaluated. Therefore, the center of gravity is unstable during transfer, which increases the safety hazards of cargo collapse and accidental falling, etc. The utility model cleverly solves various deficiencies of the existing structure by overall design of the cargo transfer device. After adopting the cargo transfer device, after the pallet and cargo are sent to the transfer station together, the weight information is obtained by the floor scale, and at the same time, the overall geometric shape of the cargo is obtained by visual or 3D scanning to obtain the shape and three-dimensional coordinate information, and based on the geometric shape, the geometric center is evaluated according to the physical shape, and the evaluated geometric center is located at the transfer station to obtain the center of gravity information. At this time, if there is a deviation in the geometric center evaluation result, an alarm is given to prevent the cargo with possible safety risks from being stored outside the warehouse. Therefore, on the one hand, the utility model obtains the center of gravity, shape, three-dimensional coordinates and weight information under the premise of realizing cargo transfer, providing necessary assistance for intelligent matching of storage stations; on the other hand, based on the evaluation of the center of gravity, the cargo with possible risks is blocked from being stored outside the warehouse, eliminating the safety hazard of cargo collapse and accidental falling due to unstable center of gravity.

[0036] like Figures 1 to 3 As shown, the cargo transfer device of this embodiment is suitable for intelligent warehousing, which includes a frame 1, a frame 2 forming a transfer station H, a floor scale 3 arranged in the frame 2 and constituting the bottom of the transfer station, an information processor 4 installed on the frame 1 and based on vision or three-dimensional scanning to obtain the coordinates and shape information of the XYZ axis of the cargo, and an alarm 5 connected to the information processor 4.
[0037] Specifically, the frame 1 includes four columns 10 fixed on the ground, and rectangular frame rods 11 fixed on the tops of the columns 10 , wherein the stand 2 is fixed on the bottoms of the columns 10 and is located above the side of the floor scale 3 .
[0038] In some specific embodiments, the frame 2 includes a frame plate 20 fixedly mounted on opposite sides of the floor scale 3, wherein the frame plate 20 is located above the side of the floor scale 3 and connected to the column 10. Avoid interference between the floor scale and the frame plate installation position. The frame plates 20 on both sides are symmetrically arranged with respect to the direction of entering and exiting the transfer station, wherein each frame plate 20 includes a straight plate 200 extending along the direction of entering and exiting the transfer station, and a folding plate 201 located at both ends of the straight plate 200 and tilted outward. The two straight plates 200 and the floor scale 3 constitute a transfer station, and a receiving bell mouth k for entering and exiting the transfer station H is formed between the two folding plates 201 located at the same end. Based on the setting of the receiving bell mouth k, it is more convenient for pallets and goods to enter and exit the transfer station.
[0039] In this example, the length of the straight board 200 is equal to the length of the pallet B; the distance between the straight boards 200 is greater than the width of the pallet B, wherein the inner wall of each straight board 200 is installed with a ball assembly 6 that can form a rolling guide contact with the side of the pallet B. Based on the guidance formed by the ball assembly 6, the pallet can enter and exit the transfer station more smoothly, so that the center of gravity of the goods can be estimated more accurately, that is, to provide safety assistance for later transfer and storage.
[0040] In some specific embodiments, the ball assembly 6 includes a ball seat 60 and a universal ball 61 exposed from the side of the ball seat 60 to form a rolling spherical contact, wherein the rolling contact formed by the universal ball 61 and the pallet B forms a motion guide.
[0041] In this example, there are two ball bearing assemblies 6 on each straight board 200 , and the two ball bearing assemblies 6 are spaced apart from each other in the front and back directions. The two ball bearing assemblies 6 on the two straight boards 200 are symmetrically distributed.
[0042] In addition, the information processor 4 uses a visual camera 40 to obtain information (of course, a scanning method that forms motion on the XYZ axis can also be used to obtain 3D modeling), and there are multiple visual cameras 40 and they are distributed and installed on the column 10 and the rectangular frame rod 11. At the same time, in order to meet the needs of use, each visual camera 40 can be slidably adjusted and installed on the corresponding column 10 and the rectangular frame rod 11 (in short, visual cameras 40 are arranged on the XYZ axis). At the same time, based on the 3D modeling information obtained by vision, the center of gravity of the goods is estimated. If the center of gravity is not on the center line of the transfer station H, the alarm 5 will sound an alarm to block the goods with safety risks from being stored outside. In this example, the information processor 4 also includes a data processing unit 41 installed on the column 10, and the information obtained is formed into a 3D model after passing through the data processing unit 41. At the same time, it needs to be further explained that the information processor 4 is a product directly purchased from outside.
[0043] In summary, the implementation process of this embodiment is as follows:
[0044] The transfer truck will drag the pallet and goods from the receiving trumpet to the transfer station. At the same time, the rolling guide formed by the universal ball on both sides will send all the pallets and goods to the corresponding transfer station, and then fall down and be guided downward by the universal ball to temporarily store the pallet and goods on the scale for transfer.
[0045] Then, during the period of temporary storage in transit, the weight information is obtained by the scale, and the overall geometric shape of the goods is obtained by visual or 3D scanning to obtain the shape and three-dimensional coordinate information, and based on the geometric shape, the geometric center is evaluated according to the entity shape, and the evaluated geometric center is located at the transit station to obtain the center of gravity information. Therefore, on the one hand, the utility model obtains the center of gravity, shape, three-dimensional coordinates and weight information to provide necessary assistance for intelligent matching of storage stations under the premise of realizing cargo transit; on the other hand, based on the evaluation of the center of gravity, the goods that may be at risk are blocked from storage, eliminating the safety hazards of cargo collapse and accidental fall due to unstable center of gravity; on the third aspect, based on the installation of the frame, interference between the scale and the shelf position is avoided, and based on the setting of the receiving horn, it is more convenient for the pallet and the goods to enter and exit the transit station; on the fourth aspect, the guide formed by the ball assembly makes the pallet enter and exit the transit station more stable, so that the center of gravity position of the goods can be more accurately estimated, that is, safety assistance is provided for later reprinting and warehousing.
[0046] The above detailed description of the utility model is intended to enable people familiar with the technology in this field to understand the content of the utility model and implement it. It is not intended to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
