[0001] This invention belongs to the field of mechanical automation, and more specifically, relates to a flipping device for automatically guiding transported goods. Background Technology

[0002] With the rapid development of industry, the demand for automation is increasing across all sectors. This unmanned process improves efficiency and ensures personal safety. In fields such as automated warehouses, it is necessary to transport items from one location to another, performing relatively complex operations such as posture changes and material additions / removals during transport. Simultaneously, it is crucial to constrain, guide, and release items within relatively confined spaces. During item transfer, some items have large loads, high speeds, and multiple degrees of freedom, requiring automatic switching between multiple movement paths. Therefore, an automated mechanism needs to be designed to achieve these functions. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this invention is to provide a flipping device for automatic guidance of transferred goods, which aims to solve the problem that existing automated warehouses have difficulty in achieving automatic switching of multiple movement paths for transferred goods in a confined space.

[0004] To achieve the above objectives, the present invention provides a flipping device for automatically guiding transported goods. The flipping device includes a limiting unit and a power unit. The limiting unit includes a support frame and a support plate. One side of the support frame is connected to the power unit, and the other side is connected to the support plate. Below the support frame is the transport space for the transported goods. The upper end of the support plate is connected to the support frame, and the lower end is used to limit the transport of the transported goods. One end of the power unit is fixed to the top plate, and the other end is connected to the limiting unit, which drives the limiting unit to flip, thereby providing clearance for the vertical movement of the transported goods.

[0005] As a further preferred embodiment, the limiting unit further includes a wear-resistant plate, which is disposed on the inner side of the support plate.

[0006] As a further preferred embodiment, the power unit includes an electric cylinder, an electric cylinder mounting base, a handle, a rotating shaft assembly, and a rotating shaft mounting base. The electric cylinder is fixed to the top via the electric cylinder mounting base, and the piston rod of the electric cylinder is hinged to one end of the handle. The other end of the handle is fixedly connected to the rotating shaft assembly to convert the pulling force of the electric cylinder into torque. The rotating shaft assembly is fixed relative to the top plate via the rotating shaft mounting base, and both ends of the rotating shaft assembly are also fixedly connected to the support frame to drive the support frame to rotate around the rotating shaft assembly as an axis.

[0007] As a further preferred embodiment, the pivot assembly includes a first pivot, a second pivot, an adapter, and a connecting tube. The first pivot and the second pivot are symmetrically arranged, with one end being a polygonal connector for fixed connection to the support frame, and the other end being a cylindrical structure for passing through the pivot mounting base and connecting to the connecting tube via the adapter. The polygonal connector of the first pivot is also used for fixed connection to the handle.

[0008] As a further preferred embodiment, one end of the adapter is hinged to the first or second rotating shaft, while the other end of the adapter is welded to the connecting round pipe.

[0009] As a further preferred embodiment, the limiting unit further includes a flip limiting seat, which is disposed directly below the support frame and fixed to the ground by a bracket, for limiting the flipping of the limiting unit. The flip limiting seat includes a pressure plate, a rubber plate and a base plate arranged sequentially from top to bottom.

[0010] As a further preferred embodiment, the base plate is provided with countersunk screws for connection with the rubber plate, and the pressure plate is connected to the rubber plate by bolts.

[0011] As a further preferred embodiment, one end of the electric cylinder mounting base is a mounting plate for connection to the top, and the other end is a fork lug structure, which is connected to the fixed end of the electric cylinder via a third rotating shaft.

[0012] As a further preferred embodiment, the third rotating shaft has a groove, and the first baffle is placed in the groove and connected to the electric cylinder mounting base to prevent the third rotating shaft from axially moving and rotating circumferentially.

[0013] As a further preferred embodiment, one end of the handle is a single-ear structure with a through hole inside that matches the polygonal connector of the first rotating shaft for fixed connection with the first rotating shaft; meanwhile, the other end of the handle is a fork-ear structure and is connected to the lead screw of the electric cylinder through a fourth rotating shaft. The fourth rotating shaft has a groove, and a second baffle is placed in the groove and connected to the handle to prevent the fourth rotating shaft from axially moving and rotating circumferentially.

[0014] In summary, the technical solutions conceived by this invention have the following beneficial effects compared with the prior art:

[0015] 1. The flipping device provided by the present invention uses the support plate in the limiting unit to constrain the movement of the transported item in the X direction and guide the movement of the transported item in the Y direction. At the same time, the power unit drives the limiting unit to flip to provide safe avoidance for the movement of the transported item in the Z direction. This realizes the automated transportation of the transported item and the automatic switching of multiple movement paths. The flipping device is installed by top suspension and uses the power unit to drive the limiting unit to flip up and down. It can make full use of the limited space, thereby constraining, guiding and releasing the item in a relatively tight space. The whole process is uninterrupted and has the characteristics of reliability, high speed and strong adaptability.

[0016] 2. At the same time, by optimizing the structure of the power unit, the present invention utilizes an electric cylinder for driving, which has the advantage of fast response speed and can quickly respond to the transport of items with high operating speed. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] like Figures 1-10 As shown, the present invention provides a flipping device for automatically guiding transported goods. The flipping device includes a limiting unit and a power unit. The limiting unit includes a support frame 1 and a support plate 4. One side of the support frame 1 is connected to the power unit, and the other side is connected to the support plate 4. Below it is the transport space for the transported goods 22. The support frame 1 is the main load-bearing structure and rigid connecting body of the flipping device. It is formed by welding rectangular tubes, steel plates, angle steel, reinforcing ribs, etc., so as to have a high load-bearing capacity to cope with the characteristics of large load and high running speed of the transported goods. The upper end of the support plate 4 is bolted to the support frame 1, and the lower end is used to limit the transport of the transported goods 22. It is the main limiting plate of the transported goods 22 and bears the load in the X direction of the transported goods. One end of the power unit is fixed to the top plate, and the other end is connected to the limiting unit to drive the limiting unit to flip, thereby providing avoidance for the vertical movement of the transported goods.

[0031] During operation, the transported item 22 has three degrees of freedom in the X, Y, and Z directions. Under the combined action of the support frame 1 and the support plate 4, the flipping device provides constraint on the movement of the transported item 22 in the X direction and guides its movement in the Y direction. At the same time, the power unit drives the limit unit to flip, which can provide safe avoidance for the movement of the transported item 22 in the Z direction. Thus, in view of the problems of large load, high running speed and multiple degrees of freedom of the transported item, it can realize the automatic switching of multiple movement paths, provide the item with limit in one direction and avoidance in another direction. Moreover, the installation form is a top-suspended structure, which can make full use of limited space. The process is unattended and has the characteristics of reliability, high speed and strong adaptability.

[0032] Furthermore, the limiting unit also includes a wear-resistant plate 5, which is disposed on the inner side of the support plate 4 and connected to the support plate 4 by screws, providing a mating surface for the transported items, having wear-resistant characteristics, and facilitating the movement of the transported items along the Y direction.

[0033] Furthermore, the power unit includes an electric cylinder 3, an electric cylinder mounting base 2, a handle 10, a rotating shaft assembly, and a rotating shaft mounting base 6. The electric cylinder 3 is a servo electric cylinder, characterized by high speed, heavy load, and high precision. It can drive the limit unit to rotate quickly, with a rotation time of 1 second when the rotation angle is 100 degrees, thus enabling rapid response to fast-moving transported items. The electric cylinder 3 is fixed to the top via the electric cylinder mounting base 2, thus achieving a top-suspended installation method, which can effectively save space and is suitable for warehouse environments with relatively limited space. At the same time, the piston rod of the electric cylinder 3 is hinged to one end of the handle 10, and the other end of the handle 10 is fixedly connected to the rotating shaft assembly to convert the pulling force of the electric cylinder 3 into torque. The rotating shaft assembly is fixed relative to the top plate via the rotating shaft mounting base 6, and both ends of the rotating shaft assembly are also fixedly connected to the support frame 1 to drive the support frame 1 to rotate around the rotating shaft assembly as an axis. The rotating shaft mounting base 6 can be fixedly connected to the ground via a bracket to achieve relative fixation with the top plate.

[0034] Furthermore, the rotating shaft assembly includes a first rotating shaft 7, a second rotating shaft 8, an adapter 11, and a connecting round tube 12. The first rotating shaft 7 and the second rotating shaft 8 are symmetrically arranged as the rotation axes of the support frame 1. One end of each shaft is a polygonal joint, preferably a square joint, for fixed connection with the support frame 1. The other end is a cylindrical structure for passing through the rotating shaft mounting seat 6 and connecting to the connecting round tube 12 via the adapter 11. The polygonal joint of the first rotating shaft 7 is also used for fixed connection with the handle 10, thereby realizing the function of transmitting the flipping torque. A copper sleeve 9 is placed between the first rotating shaft 7 or the second rotating shaft 8 and the rotating shaft mounting seat 6 to reduce friction. One end of the adapter 11 has a U-shaped opening for hinged connection with the first rotating shaft 7 or the second rotating shaft 8, which facilitates disassembly. The other end of the adapter 11 is welded to the connecting round tube 12. The mutual cooperation between the adapter 11 and the connecting round tube 12 enables torque transmission and avoids unnecessary cost waste caused by integral molding.

[0035] Furthermore, the limiting unit also includes a flip-up limiting seat, which is located directly below the support frame 1 and fixed to the ground by a bracket. It is used to limit the flipping of the limiting unit. The flip-up limiting seat includes a pressure plate 20, a rubber plate 21 and a base plate 19 arranged sequentially from top to bottom. The base plate 19 is provided with countersunk screws for connecting with the rubber plate 21. The rubber plate 21 cooperates with the support frame 1 to provide a buffering effect. At the same time, the pressure plate 20 and the rubber plate 21 are connected by bolts to press the rubber plate 21 tightly.

[0036] Furthermore, one end of the electric cylinder mounting base 2 is a mounting plate for connecting to the top, and the other end is a fork lug structure, which is connected to the fixed end of the electric cylinder 3 through the third rotating shaft 13. The third rotating shaft 13 is the rotation shaft of the electric cylinder 3. A groove is opened on the third rotating shaft 13, and the first baffle 14 is placed in the groove and connected to the electric cylinder mounting base 2 with screws to prevent the third rotating shaft 13 from axially moving and circumferentially rotating.

[0037] Furthermore, one end of the handle 10 is a single-ear structure with a through hole inside that matches the polygonal connector of the first rotating shaft 7 for fixed connection with the first rotating shaft 7; at the same time, the other end of the handle 10 is a fork-ear structure and is connected to the lead screw of the electric cylinder 3 through the fourth rotating shaft 18. The fourth rotating shaft 18 has a groove, and the second baffle 23 is placed in the groove and connected to the handle 10 with a screw to prevent the fourth rotating shaft 18 from axial movement and circumferential rotation.

[0038] Figure 2 The state shown is the limit state when the flipping mechanism flips at an angle of 0. At this time, the rectangular beam of the support frame 1 is in contact with the bottom flipping limit seat. The transported item 22 moves along the x direction until it is in contact with the plane of the wear-resistant plate 5, and then it has moved into place. If the transported item 22 needs to continue to move along the y direction, it can move under the guidance of the wear-resistant plate 5. If the transported item 22 needs to continue to move along the x direction or along the z direction, the entire flipping mechanism needs to flip to avoid the movement trajectory of the transported item 22.

[0039] First, the action signal is sent to the electric cylinder 3, and the piston rod of the electric cylinder 3 retracts. The motor side support of the electric cylinder 3 rotates around the third rotating shaft 13, and the piston rod support rotates around the fourth rotating shaft 18. At the same time, the handle 10 is pulled. The handle 10 and the first rotating shaft 7 have a square interface. Together, they rotate clockwise around the rotating shaft mounting seat 6 under the action of the copper sleeve 9, which drives the adapter 11, the connecting round tube 12, and the second rotating shaft 8 to move in linkage. Finally, the support frame 1 is driven to rotate around the two rotating shaft mounting seats 6 until it rotates about 100 degrees and stops. At this time, the transported item 22 can move in the x or z direction, thus completing the avoidance.

[0040] If the limit state is restored, the action signal is sent to the electric cylinder 3. The piston rod of the electric cylinder 3 pushes out and pushes the handle 10. The handle 10, the first rotating shaft 7, the adapter 11, the connecting round pipe 12, the second rotating shaft 8, etc. do not rotate relative to each other and rotate counterclockwise around the rotating shaft mounting seat 6. At the same time, it drives the support frame 1 to rotate counterclockwise until the support frame 1 flips to 0 degrees. At the same time, the rectangular beam of the support frame 1 contacts the flip limit seat, which plays a buffering role.

[0041] Furthermore, the first washer 10 is located on the outer side of the single lug structure of the handle 10, the second washer 16 is located on the inner side of the fork lug structure of the handle 10, and the third washer 17 is located on the inner side of the fork lug structure of the electric cylinder mounting seat 2, for intermittent compensation and wear resistance.

[0042] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
