[0043] The following description, in conjunction with the accompanying drawings, provides a more detailed account of a lifting device, container transfer equipment, and method according to the present invention, illustrating preferred embodiments of the invention. It should be understood that those skilled in the art can modify the invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the invention.

[0044] The invention is described more specifically by way of example in the following paragraphs with reference to the accompanying drawings. The advantages and features of the invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the invention.

[0045] like Figure 1-2 As shown in the figure, an embodiment of the present invention proposes a lifting device 6, including a coupling 61, an upper sliding rod 62, a central turntable 63, a lower sliding rod 64, a connecting shaft 65, a cylinder 66, and a bearing seat 67. One end of the upper sliding rod 62 is fixedly mounted on the coupling 61, and the other end passes through the central turntable 63 and is slidably connected to the central turntable 63; one end of the lower sliding rod 64 passes through the central turntable 63 and is slidably connected to the central turntable 63, and the other end is connected to the connecting shaft 65; the bearing seat 67 is rotatably connected to the coupling 61; the fixed end of the cylinder 66 is installed at a designated position, and the telescopic end is connected to the bearing seat 67, and the cylinder 66 is used to drive the coupling 61 and the bearing seat 67 to move up and down.

[0046] By sliding between the upper sliding rod 62, the central turntable 63, and the lower sliding rod 64, the device can move up and down smoothly and be precisely guided, thus improving the stability of the device; it can also achieve the maximum stroke within a limited range.

[0047] like Figure 3-4 As shown in the figure, the present invention provides a container transfer device, including the lifting device 6 as described above, and also including a first conveying platform 1, a second conveying platform 2, a main shaft 3, multiple material picking devices 4, a guiding device 5 and a rotating device 7.

[0048] Specifically, the main shaft 3 is rotatably mounted between the first conveyor table 1 and the second conveyor table 2 via the rotating device 7, with both ends positioned above the first conveyor table 1 and the second conveyor table 2, respectively. Multiple material-grabbing devices 4 are respectively installed at both ends of the main shaft 3, used to grab the material 110 on the first conveyor table 1 and place the material 110 into the container on the second conveyor table 2 under the rotation of the rotating device 7. The guiding device 5 is disposed between the main shaft 3 and the container, used to guide and position the material 110 in the material-grabbing device 4 relative to the container. The lifting device 6 has both ends connected to the main shaft 3 and the rotating device 7, used to control the up-and-down movement of the main shaft 3 and the material-grabbing device 4; that is, the coupling 61 is connected to the main shaft 3. The connecting shaft 65 is connected to the rotating device 7. The bearing seat 67 is rotatably connected to the main shaft 3. The rotating device 7 is used to drive the main shaft 3, the material-grabbing device 4, and the lifting device 6 to rotate.

[0049] In a specific example, material 110 is often a carrier of contents such as solutions or powders, i.e., an inner container. The outer container 100 is often a protective shell for the inner container. After the inner container is placed into the outer container 100, further sealing can protect the inner container.

[0050] In addition, combined Figure 5 As shown, this embodiment also includes a base 8, a mounting base 9, and a bottom plate 10; the first conveying platform 1, the second conveying platform 2, and the mounting base 9 are all mounted on the base 8; the main shaft 3 and the guide device 5 are both mounted on the base 8 via the mounting base 9; the main shaft 3 is rotatably connected to the mounting base 9; the lifting device 6 passes through the base 8 and is connected to the rotating device 7, and the lifting device 6 is rotatably connected to the base 8; the lifting device 6 and the rotating device 7 are both mounted on the bottom plate 10; the guide device 5 is slidably connected to the mounting base 9.

[0051] More specifically, the connecting shaft 65 passes through the base plate 10 and is rotatably connected to the base plate 10; the bearing seat 67 is rotatably and slidably installed in the mounting base 9; and the fixed end of the cylinder 66 is installed on the base plate 10.

[0052] In this embodiment, as Figure 5-6 As shown, the guiding device 5 includes a mounting plate 51, a protective plate 52, and a pressure plate 53. Specifically, one end of the mounting plate 51 is mounted on the mounting base 9; the main shaft 3 passes through one end of the mounting plate 51 and is rotatably connected to the mounting base 9; the protective plate 52 is mounted on the other end of the mounting plate 51 and is located between the mounting plate 51 and the pressure plate 53; the mounting plate 51, the protective plate 52, and the pressure plate 53 form a guide plate; the guide plate has a first guide hole corresponding to the material 110 on the side near the material 110; the guide plate has a second guide hole corresponding to the container on the side near the container; the first guide hole and the second guide hole are connected; the material 110 enters the container sequentially through the first guide hole and the second guide hole.

[0053] In addition, continue to refer to Figure 6 As shown, the guiding device 5 further includes a plurality of first elastic elements 56 and a plurality of second elastic elements 57. Specifically, one end of the first elastic element 56 is mounted on one end of the mounting plate 51; the first elastic element 56 is located between the main shaft 3 and the mounting plate 51; the two ends of the second elastic elements 57 are respectively connected to the mounting base 9 and the mounting plate 51. This allows the material 110 (inner container) to accurately enter the outer container 100.

[0054] Preferably, both the first elastic element 56 and the second elastic element 57 can be springs. By controlling the sequence of actions through the two springs (i.e., the first elastic element 56 and the second elastic element 57), flexible positioning and guidance are achieved, ensuring that the inner container and the outer container 100 are nested and assembled.

[0055] Additionally, the mounting base 9 includes an upper mounting base and a lower mounting base. Specifically, the upper mounting base is fixedly mounted on the lower mounting base by a fixing rod; the lower mounting base is mounted on the base 8. Furthermore, the mounting plate 51 is slidably mounted on the upper mounting base by multiple mounting rods. More specifically, the upper mounting base is provided with sliding holes; the mounting rods are slidably mounted in the sliding holes, allowing the mounting plate 51 to move up and down on the upper mounting base.

[0056] Further reference Figure 5-6As shown, the guiding device 5 further includes multiple elastic washers 54 and multiple guide cylinders 55. Specifically, the multiple elastic washers 54 are respectively located between the mounting plate 51 and the protective plate 52, and between the protective plate 52 and the pressure plate 53; the guide cylinders 55 are located inside the guide plate, and both the first guide hole and the second guide hole are located between the guide cylinders 55; the multiple elastic washers 54 are respectively sleeved on the outer side of the multiple guide cylinders 55. Each guide cylinder 55 may be fitted with multiple elastic washers 54. For example, each guide cylinder 55 may be fitted with two elastic washers 54, with the two elastic washers 54 respectively located between the mounting plate 51 and the protective plate 52, and between the protective plate 52 and the pressure plate 53.

[0057] In a specific example, by setting the guide device 5, the guide plate first presses down on the outer container 100 during each feeding process to ensure accurate positioning, and then the inner container enters the outer container 100 through the guide plate under the action of the feeding device 4 on the main shaft 3, so as to avoid collision between the inner container and the outer container 100 during the nesting assembly process and improve the yield.

[0058] In this embodiment, reference continues to be made to Figure 1-2 and Figure 4-5 As shown, the two ends of the coupling 61 are respectively connected to the main shaft 3 and the upper slide rod 62; one end of the upper slide rod 62 is fixedly installed on the coupling 61, and the other end passes through the central turntable 63 and is slidably connected to the central turntable 63; one end of the lower slide rod 64 passes through the central turntable 63 and is slidably connected to the central turntable 63, and the other end is connected to the connecting shaft 65; the connecting shaft 65 passes through the base plate 10 and is rotatably connected to the base plate 10; the main shaft 3 passes through the mounting base 9 and the bearing seat 67 and is connected to the bearing seat 67; the bearing seat 67 is rotatably and slidably installed in the mounting base 9; the fixed end of the cylinder 66 is installed on the base plate 10, and the telescopic end is connected to the bearing seat 67.

[0059] With the coupling 61 in place, this device features guiding, torque transmission, and precise drive. In a specific example, under the transmission action of the upper slide rod 62, the lower slide rod 64, and the bearing seat 67, the connecting shaft 65 rotates, driving the central turntable 63 to rotate simultaneously, and the coupling 61 rotates, enabling smooth vertical displacement. Because the hollow structure allows for cable routing, vertical movement and rotation do not affect the cable routing.

[0060] In a specific example, the turntable 63 has a first through hole for the upper sliding rod 62 to pass through and a second through hole for the lower sliding rod 64 to pass through. Specifically, the bearing seat 67 is rotatably connected to a bearing component; the shaft seat assembly 31 passes through the bearing component; the side wall of the bearing component has a through opening, and the shaft seat assembly 31 has a mounting port corresponding to the through opening; the shaft seat assembly 31 is installed inside the bearing component by means of a clamp passing through the through opening and the mounting port in sequence. When the telescopic end of the cylinder 66 extends or retracts, it sequentially drives the bearing seat 67 and the bearing component to move up and down. At this time, the upper sliding rod 62 moves up and down along the first through hole on the turntable 63, and the lower sliding rod 64 moves up and down along the second through hole on the turntable 63; simultaneously, the up and down movement of the bearing component can drive the shaft seat assembly 31 to move up and down, thereby sequentially driving the main shaft 3 and the material handling device 4 to move up and down. This allows the device to move up and down smoothly and guide the movement precisely, improving the stability of the device; it can also achieve the maximum stroke within a limited range.

[0061] When moving downwards, the material-grabbing device 4 on the first conveyor table 1 can pick up the material 110 through the vacuum suction cup 41. As the main shaft 3 moves downwards, it presses against the first elastic element 56 in the guide device 5, while the upper mounting seat in the mounting base 9 presses against the second elastic element 57. At this time, the material 110 in the material-grabbing device 4 on the second conveyor table 2 can be inserted into the first guide hole of the guide plate. Furthermore, under the elastic action of the first elastic element 56 and the second elastic element 57, the guide plate slowly inserts the outer container 100 on the second conveyor table 2 into the second guide hole, achieving precise guidance and positioning, and improving the precise assembly of the material 110 and the outer container 100.

[0062] In one embodiment, reference continues Figure 2 and Figure 4 As shown, the rotating device 7 includes a drive device 71 and a timing belt 72. Specifically, the fixed end of the drive device 71 is mounted on the base plate 10, and the movable end passes through the base plate 10; the movable end of the drive device 71 is connected to the connecting shaft 65 via the timing belt 72.

[0063] The drive unit 71 includes a drive motor.

[0064] In a specific example, the drive motor starts, causing the synchronous belt 72 to rotate, which in turn drives the connecting shaft 65 to rotate, thereby sequentially driving the sliding rod 64, the central turntable 63, the upper sliding rod 62, the coupling 61, the shaft seat assembly 31, the main shaft 3, and the material handling device 4 to rotate. The rotation angle is usually 180° depending on the position of the first conveyor table 1 and the second conveyor table 2, with the first conveyor table 1 parallel to the second conveyor table 2.

[0065] In this embodiment, as Figure 7As shown, in one embodiment, the material handling device 4 includes a vacuum suction cup 41, a guide sleeve 42, and an air passage pipe; a vacuum chamber 43 is provided inside the main shaft 3; the vacuum suction cup 41 is mounted on the main shaft 3 and communicates with the vacuum chamber 43; the guide sleeve 42 is sleeved on the outside of the vacuum suction cup 41; the lifting device 6 has a first through hole in the middle of the bearing seat 67, coupling 61, central turntable 63, and connecting shaft 65; one end of the air passage pipe communicates with the vacuum chamber 43, and the other end passes through the first through hole and is connected to the vacuum pump.

[0066] In this embodiment, the main shaft 3 is connected to the lifting device 6 via a bearing assembly 31; the bearing assembly 31 passes through the guide device 5; the middle part of the bearing assembly 31 is provided with a second through hole corresponding to the first through hole; the air pipe passes through the second through hole and the first through hole in sequence.

[0067] Preferably, there are multiple material handling devices 4, and each material handling device 4 also has multiple vacuum suction cups 41. All of the multiple vacuum suction cups 41 are connected to the vacuum chamber 43.

[0068] In addition, such as Figure 8 As shown, this embodiment also proposes a container transfer method using the container transfer equipment described above, including the following steps:

[0069] S1. The lifting device 6 controls the material picking device 4 on the main shaft 3 to descend, and the material picking device 4 picks up the material 110 from the first conveyor table 1.

[0070] S2. Then, the lifting device 6 controls the lifting of the material taking device 4, and the rotating device 7 drives the main shaft 3 to rotate, so that the material taking device 4 with material 110 is located directly above the container in the second conveyor table 2, and the empty material taking device 4 is located on the first conveyor table 1.

[0071] S3. Then, the lifting device 6 controls the descent of the material-picking device 4, so that the material-picking device 4 with material 110 can place the material 110 into the container through the guidance and positioning of the guiding device 5, and the empty material-picking device 4 grabs the material 110 on the first conveyor table 1 to prepare for the next step.

[0072] In this embodiment, the lifting device 6 controls the lowering of the picking device 4 on the main shaft 3, which then picks up the material 110 from the first conveyor table 1. The lifting device 6 then controls the raising of the picking device 4, and the rotating device 7 drives the main shaft 3 to rotate 180°, so that the picking device 4 with the material 110 is positioned directly above the container in the second conveyor table 2, while the empty picking device 4 is positioned on the first conveyor table 1. The lifting device 6 then controls the lowering of the picking device 4, allowing the picking device 4 with the material 110 to place it into the container through the guidance and positioning of the guiding device 5, while the empty picking device 4 picks up the material 110 from the first conveyor table 1, preparing for the next step. Thus, completing one picking action simultaneously completes one unloading operation.

[0073] In summary, the lifting device, container transfer equipment, and method proposed in this invention have the following advantages:

[0074] The device employs a combination of a coupling, upper slide rod, central turntable, lower slide rod, connecting shaft, cylinder, and bearing housing. One end of the upper slide rod is fixed to the coupling, while the other end passes through and slidably connects to the central turntable. One end of the lower slide rod passes through and slidably connects to the central turntable, while the other end is connected to the connecting shaft. The bearing housing rotatably connects to the coupling. The fixed end of the cylinder is installed in a designated position, and the telescopic end connects to the bearing housing, used to drive the coupling and bearing housing to move up and down. The bearing housing, coupling, central turntable, and connecting shaft all share a first through hole for the material handling device to pass through. This device can simultaneously perform lifting, rotation, and material handling functions to transfer materials, expanding its applicability. It also allows for smooth vertical displacement and precise guided movement, improving stability; and it can achieve maximum stroke within a limited range.

[0075] In addition, the device comprises a first conveyor table, a second conveyor table, a main shaft, multiple material handling devices, a guiding device, and a rotating device. The main shaft is rotatably mounted between the first and second conveyor tables via the rotating device, with both ends positioned above the first and second conveyor tables respectively. Multiple material handling devices are respectively mounted at both ends of the main shaft to grip materials on the first conveyor table and, under the rotation of the rotating device, place the materials into containers on the second conveyor table. The guiding device is positioned between the main shaft and the containers to guide and position the materials in the material handling devices relative to the containers. A coupling is connected to the main shaft; a connecting shaft is connected to the rotating device; a bearing seat is rotatably connected to the main shaft; and the rotating device drives the main shaft, material handling devices, and lifting device to rotate. This device enables rapid material transfer, nested assembly of multiple containers, and precise nesting of containers and materials, thus improving transfer efficiency.

[0076] In addition, the guide plate, the first elastic element and the second elastic element in the guiding device enable the material to enter the outer container accurately, realize flexible positioning and guidance, and ensure the nested assembly of the material and the outer container.

[0077] Therefore, this device can achieve precise nesting of containers and materials and improve transfer efficiency.

[0078] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
