Description

Technical Field

[0001] This invention relates to the field of conveying equipment, and specifically provides a magnetic levitation logistics system. Background Technology

[0002] In recent years, many high-end manufacturing industries such as lithium batteries, pharmaceuticals, and semiconductors have increasingly started to use magnetic levitation logistics technology for material transportation. With the rapid development of new energy vehicles, the use of magnetic levitation logistics systems is also being explored in battery mass production lines.

[0003] Magnetic levitation logistics systems use a moving element as the carrier for material transport. Currently, most magnetic levitation logistics systems use mechanical limiting (V-shaped rollers, sliders) to support the moving element. This support method prevents the moving element from escaping the constraint of the guide rail in the direction of gravity, thus making it impossible to weigh the moving element itself. At the same time, the pallet is usually fixedly connected to the moving element, making it impossible to weigh the pallet itself. Therefore, if it is necessary to weigh materials on a magnetic levitation logistics system, offline weighing is usually used. This involves transporting the materials to a dedicated weighing device via a handling mechanism. This increases the handling equipment, leading to high equipment costs. In addition, it requires communication between the handling equipment, the logistics system, and the weighing device, resulting in complex control programs. Offline weighing also slows down the conveying cycle, especially when the conveyed materials are equipped with clamping fixtures. Furthermore, there is a risk of damaging the materials during handling.

[0004] Accordingly, there is a need in the field for a magnetic levitation logistics system to solve the above problems. Summary of the Invention

[0052] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings and in conjunction with a magnetic levitation logistics system. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0053] It should be noted that in the description of this invention, terms such as "upper," "lower," "left," "right," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the relevant devices or elements must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, ordinal numbers such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0054] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0055] Furthermore, in order to more clearly demonstrate the core technical solution of the present invention, the description of the known structures of the magnetic levitation logistics system is omitted in the following description. However, this omission is only for the convenience of description and does not mean that the magnetic levitation logistics system can be without these structures.

[0056] like Figure 1-12 As shown, this invention proposes a magnetic levitation logistics system, including a conveying body 1 and a movable component 2 movably mounted on the conveying body 1. The movable component 2 is a split structure. The magnetic levitation logistics system also includes a weighing device, which includes:

[0057] Weighing unit 3, which is disposed on any side around the conveying body 1;

[0058] The lifting unit 4 is disposed on the weighing unit 3. The lifting unit 4 abuts against the moving part assembly 2 to separate the moving part assembly 2. The weighing unit 3 weighs the side of the moving part assembly 2 that carries the object.

[0059] In this embodiment, the moving component 2 is movably mounted on the conveying body 1 of the magnetic levitation logistics system. The moving component 2 is connected to the conveying body 1 via guide rails and sliders. Four sets of sliders are located below the moving component 2, forming a sliding pair with the guide rails mounted on the conveying body 1. The sliders and guide rails are mechanically limited, preventing them from separating. This reduces the frictional resistance between the sliders and guide rails under magnetic levitation. During transportation, the end of the moving component 2 carrying the material and the end moving on the conveying body 1 remain together, improving stability. The moving component 2 adopts a split structure. When it reaches the weighing position, the lifting unit 4 will abut against the moving component 2, causing the split moving component 2 to separate. The entire weight of the side of the moving component 2 carrying the material will fall on the lifting unit 4. Since the lifting unit 4 is mounted on the weighing unit 3, the material can be weighed online through the weighing unit 3. It should be noted that the installation positions of the weighing unit 3 and the lifting unit 4 can be appropriately adjusted by those skilled in the art based on factors such as installation space. The weighing unit 3 may be located on any side of the conveying body 1, including but not limited to being below, on one side to the left or right, or on both sides and above the conveying body 1.

[0060] The present invention designs the mover in a split manner to form the mover component 2, and realizes the separation of the mover component 2 in the logistics system through the lifting unit 4, and further weighs it through the weighing unit 3. Therefore, without deviating from the above technical concept, it is also considered to fall within the protection scope of the present invention to simply improve the application scenario and conventional structure of the magnetic levitation logistics system.

[0061] Based on the above embodiments, see [reference] Figure 2 The mover assembly 2 adopts a split structure. Specifically, the first mover 5 is slidably connected to the conveying body 1 via a slider and guide rail, while the second mover 6 is separately connected to the first mover 5. In this embodiment, the first mover 5 and the second mover 6 are in an upper-lower layer positional relationship. When the mover assembly 2 moves to the weighing position of the logistics system, the lifting unit 4 abuts against the second mover 6, thereby causing the second mover 6 to move vertically and separate from the first mover 5. Combined with the description of the above embodiment, weighing is achieved. It should be noted that in this embodiment, the mover assembly 2 is divided into two parts and has an upper-lower layer structure. However, in some other embodiments, the mover assembly 2 can be composed of multiple movers combined and installed. Furthermore, the combination of the mover assembly 2 can also adopt a non-upper-lower layer relationship, such as in a suspended conveyor. The mover assembly 2 can also adopt an inner-outer layer structure combination.

[0062] Based on the above embodiments, see [reference] Figures 2 to 4A fastener 7 is installed between the first mover 5 and the second mover 6. The fastener 7 locks the first mover 5 and the second mover 6. The fastener 7 also has an unlocking function. The fastener 7 is unlocked by the pusher unit 4 abutting against the fastener 7. This can ensure that the separate first mover 5 and the second mover 6 are stably attached during the material conveying process of the logistics system, and improve the stability of the material conveying on the mover assembly 2. When the weighing position of the logistics system is reached, the fastener 7 is unlocked under the action of the pusher unit 4, so that the second mover 6 can be lifted by the pusher unit 4 and disengaged from the first mover 5 to achieve weighing.

[0063] Based on the above embodiments, see [reference] Figures 4 to 6 The fastener 7 may include a mounting part 8 and a fastening part 9. The mounting part 8 is used to connect with the second moving part 6, and the fastening part 9 serves to lock. When the fastening part 9 abuts against the lifting unit 4, the locking state between the first moving part 5 and the second moving part 6 will be released by the abutting force of the lifting unit 4, and the second moving part 6 can be lifted off the first moving part 5 to achieve separation. Specifically, the fastening part 9 and the mounting part 8 form a fastener 7 with a main L-shaped shape. There is a certain width gap between the fastening part 9 and the second moving part 6, so that the first moving part 5 can be installed in the width gap between the two. The fastening part 9 may abut against the lower surface of the first moving part 5, or it may have a certain gap with the lower surface of the first moving part 5. The lower surface of the second moving part 6 presses against the upper surface of the first moving part 5 to form a stable connection.

[0064] Based on the above embodiments, the fastening part 9 is unlocked after abutting with the lifting unit 4. After weighing, the fastening part 9 loses the abutment of the lifting unit 4, and the first mover 5 and the second mover 6 are relocked. The fastening part 9 can be reset to abutting position. For example, an elastic element 10, such as a spring, can be used. When the fastening part 9 receives the abutting force, the fastening part 9 contracts and the spring is compressed. When the abutting force disappears, the spring releases its elasticity and resets the fastening part 9 to the locked position.

[0065] Based on the above ideas, specifically, in one of the first embodiments, such as Figure 4 As shown, the elastic element 10 can be disposed on the mounting part 8, and the fastening part 9 is movably disposed on the mounting part 8. The elastic element 10 is located between the mounting part 8 and the fastening part 9, and locking and unlocking are achieved by moving the fastening part 9.

[0066] In addition, in the second embodiment of the elastic buckle 7, the mounting part 8 is movably disposed on the second moving part 6, and the elastic element 10 also interacts between the mounting part 8 and the second moving part 6. The mounting part 8 can move with the fastening part 9 to achieve unlocking and locking.

[0067] It should be noted that the locking and unlocking of buckle 7 is not limited to the two methods mentioned above. There are other structures that enable the locking and unlocking of buckle 7, which will not be elaborated on here.

[0068] Based on the above embodiments, refer to Figure 4 In a first embodiment of the fastener 7, the mounting part 8 and the second moving part 6 are connected by bolts. A mounting groove 12 is provided on the mounting part 8. The direction of the mounting groove 12 is along the width direction of the first moving part 5, that is, perpendicular to the conveying direction. The fastening part 9 is slidably disposed in the mounting groove 12. By installing the elastic element 10 in the mounting groove 12, the fastening part 9 can be moved away from the mounting groove 12. A round hole can be provided on the fastening part 9 to position the elastic element 10. The fastening part 9 is designed as an L-shape, with a gap between the long end face and the second moving part 6, which is used to limit the first moving part 5 within the gap. At the same time, in order to prevent the fastening part 9 from being ejected from the mounting groove 12 by the elastic element 10, a limiting element is required for limiting.

[0069] It should be noted that there are multiple ways to limit the position; this embodiment describes one of them. See references 4 to 5. Figure 6 A U-shaped groove 13 is formed on the fastening part 9. A baffle 11 is installed on the mounting part 8. The baffle 11 is installed at the opening of the mounting groove 12 and extends into the U-shaped groove 13. The baffle 11 abuts against the side wall of the U-shaped groove 13 to form a limit, so that the fastening part 9 will not detach from the mounting groove 12 under the action of the elastic member 10. There are multiple ways to cooperate between the fastener 7 and the first moving part 5 with the above structure. One way is to form a rectangular through hole on the first moving part 5. The fastener 7 passes through the rectangular through hole. The width of the rectangular through hole corresponds to the width of the fastener 7 after the fastening part 9 is contracted into the mounting groove 12. Specifically, four fasteners 7 are provided on the second moving part 6, and four rectangular through holes are also provided corresponding to the fasteners 7. When the fastener 7 is lifted by the pushing unit 4, the fastening part 9 is contracted into the mounting groove 12, the second moving part 6 is unlocked from the first moving part 5, the overall width of the fastener 7 is reduced, and it is retracted into the rectangular through hole, thereby achieving separation and weighing the material.

[0070] Based on the above embodiments, the pushing unit 4 abuts against the fastening part 9, thereby unlocking the second moving part 6 and the first moving part 5, and separating them under the action of the pushing unit 4. There are various structures that can unlock the fastening part 9 and push the second moving part 6 and the first moving part 5 to separate. Among them, the first embodiment is described in [reference]. Figure 7 and Figure 8The lifting component 14 of the lifting unit 4 moves on the weighing unit 3. It can move in the same direction as the weighing unit 3 or in opposite directions. After moving, the lifting component 14 abuts against the fastening part 9. The lifting component 14 will generate an upward pushing force on the fastening part 9. The horizontal component force causes the fastening part 9 to retract into the mounting groove 12, and the vertical component force lifts the fastener 7 together with the second moving part 6 to achieve weighing.

[0071] In the second embodiment, the lifting component 14 of the lifting unit 4 is installed on the weighing unit 3 and located on the travel path of the fastening part 9 along the conveying direction. The contact surface between the lifting component 14 and the fastening part 9 is curved. During the movement of the first mover 5, the fastening part 9 will contact the curved part of the lifting component 14. The contact end of the curved surface will exert an upward force on the fastening part 9. The horizontal component force will cause the fastening part 9 to retract into the inward mounting groove 12, and the vertical component force will lift the fastener 7 and the second mover 6, thereby separating the second mover 6 from the first mover 5 to achieve weighing. The curved contact surface of the lifting component 14 can be designed by those skilled in the art according to the lifting requirements.

[0072] It should be noted that any structure that moves by applying force to the fastening part 9 should fall within the protection scope of this invention.

[0073] Based on the embodiment of the first recommendation unit 4 described above, see the following... Figure 7 and Figure 8 The lifting assembly 14 moves under the action of the corresponding driving component. In this embodiment, it is specifically mounted on the weighing unit 3 via the lifting bracket 17. The drive motor 15 is installed in the middle position of the lifting bracket 17 by welding or screwing. The output end of the drive motor 15 is equipped with a gear. There are two lifting assemblies 14, which are slidably mounted on both sides of the lifting bracket 17. The lifting assembly 14 meshes with the gear on the drive motor 15 through the rack 16. Guide rods 18 are also installed on both sides of the lifting bracket 17. The guide rods 18 pass through the lifting assembly 14 and provide guidance for the movement of the lifting assembly 14 on the lifting bracket 17.

[0074] Based on the above embodiments, see [link to relevant documentation]. Figure 7 The lifting assembly 14 adopts the form of lifting roller 21, with a support plate 19 as a bracket. The guide rod 18 passes through the support plate 19 to provide guidance for its movement. The support frame is connected to the rack 16 to form a transmission connection. The wheel frame 20 and the lifting roller 21 are installed on the support frame. The lifting roller 21 is the part that contacts the fastening part 9. The part of the fastening part 9 that contacts the lifting roller 21 is set with an inclination angle, which makes it easy for the lifting roller 21 to lift the fastening part 9. The lifting roller 21 can also effectively reduce wear and vibration and extend service life.

[0075] See Figures 9 to 12 This is a schematic diagram of the motion state based on one embodiment of the present invention. The lifting assembly 14 moves towards the fastening part 9 under the drive of the drive motor 15. Figure 9 The lifting roller 21 initially abuts against the fastening part 9. A chamfer is provided on the side of the fastening part 9 to facilitate the insertion of the lifting roller. Figure 10 This is the state when the lifting roller 21 compresses the fastening part 9 into the mounting groove 12. Figure 11 This is the state where the lifting roller 21 extends below the fastening part 9 and the mounting part 8. At this time, the fastener 7 has been lifted by the lifting roller 21, and the second moving part 6 and the first moving part 5 have begun to separate. Figure 12 The lifting roller 21 pushes the fastener 7 into the rectangular through hole on the first mover 5. At this time, the fastening part 9 is reset under the action of the elastic member 10 and is locked in the through hole under the action of the rectangular through hole. At this time, the weighing state is entered. After the weighing is completed, the above state can be reversed to complete the relocking of the second mover 6 and the first mover 5.

[0076] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
