Description

Technical Field

[0001] This utility model relates to the field of magnetic drive track conveying technology, specifically to a magnetic drive logistics track changing system. Background Technology

[0002] In modern production workshops, the transport of products or parts is indispensable. Magnetic drive conveyor lines are common automated equipment, often used in the assembly line production and transport processes. A magnetic drive conveyor line is a transport system that uses trolleys equipped with magnets, which are mounted on tracks with coiled stators. The trolleys are moved along the tracks by electromagnetic drive.

[0003] In existing magnetic drive conveyor systems, logistics carts require an external rotating mechanism to turn or change tracks. When turning or changing tracks, the rotating mechanism must first change the forward direction of the logistics cart so that it can move in a specific direction. This results in low turnover efficiency of the logistics carts and is not conducive to improving the production efficiency of enterprises. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a magnetic drive logistics track-changing system, which can improve the track-changing efficiency of logistics vehicles and increase enterprise production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A magnetically driven logistics track-changing system includes several logistics trolleys and a first conveying module, a second conveying module, and a connecting module arranged in an L-shape. The first and second conveying modules are connected by the connecting module. The first conveying module includes a first conveying channel and multiple first track stators distributed along the first conveying channel. The second conveying module includes a second conveying channel and multiple second track stators distributed along the second conveying channel. Each logistics trolley is equipped with a permanent magnet array that cooperates with the first and second track stators. The connecting module includes a connecting platform, a first arc-shaped guide rail, a first steering stator, and a first driving component that drives the first arc-shaped guide rail to move up and down. The bottom of each logistics trolley is equipped with supporting rollers and guide members. When turning, the guide members extend into the first arc-shaped guide rail, and the first steering stator cooperates with the permanent magnet array to drive the logistics trolley to move along the first arc-shaped guide rail so that the logistics trolley can transfer between the first and second conveying modules. By setting arc-shaped guide rails and steering stators on the docking platform, and setting guide components that cooperate with the arc-shaped guide rails on the logistics carts, the logistics carts can automatically turn with the cooperation of the guide components and arc-shaped guide rails, eliminating the need for additional rotating components, reducing equipment waiting time, improving the turnover efficiency of logistics carts, and thus improving the production efficiency of enterprises.

[0007] As a preferred technical solution, the support rollers are located on opposite sides of the permanent magnet array, and the guide is located on the side of the support rollers away from the permanent magnet array.

[0008] As a preferred technical solution, the guide member is a guide rod extending vertically downward, and the lower end of the guide rod is provided with a guide roller. The axial direction of the guide roller coincides with the axial direction of the guide rod, and the guide roller is located above the support roller.

The guide component cooperates with the second arc-shaped guide rail to transfer the logistics trolley between the second and third conveying modules, and the guide component cooperates with the linear guide rail to transfer the logistics trolley between the first and third conveying modules. By setting up a first arc-shaped guide rail, a second arc-shaped guide rail, and a linear guide rail, and a first drive assembly, a second drive assembly, and a third drive assembly that drive the first arc-shaped guide rail, the second arc-shaped guide rail, and the linear guide rail to move up and down respectively, the logistics cart can be switched between the first conveying module, the second conveying module, and the third conveying module as needed. For example, when the logistics cart needs to be switched between the first conveying module and the second conveying module, the first drive assembly raises the first arc-shaped guide rail, allowing the guide member to extend into the first arc-shaped guide rail. At the same time, the second drive assembly and the third drive assembly lower the second arc-shaped guide rail and the linear guide rail respectively, causing the guide member to disengage from the second arc-shaped guide rail and the linear guide rail. This allows the logistics cart to switch between the first conveying module and the second conveying module with the cooperation of the guide member and the first arc-shaped guide rail.

The third conveying module 30 includes a third conveying channel 31 and a plurality of third track stators 32 distributed along the third conveying channel 31.

[0042] The logistics trolley 50 is equipped with a permanent magnet array 51 that cooperates with the first track stator 12, the second track stator 22, and the third track stator 32. The connecting module 40 includes a connecting platform 41, a first arc-shaped guide rail 42, a second arc-shaped guide rail 43, a linear guide rail 44, a first steering stator 461 that cooperates with the permanent magnet array 51 to drive the logistics trolley 50 along the first arc-shaped guide rail 42, a second steering stator 462 that cooperates with the permanent magnet array 51 to drive the logistics trolley 50 along the second arc-shaped guide rail 43, a straight-line drive stator 463 that cooperates with the permanent magnet array 51 to drive the logistics trolley 50 along the linear guide rail 44, and a drive stator 463 that drives the first arc-shaped guide rail 42.
