The track body 100 comprises a linear guide rail 4, and each roller assembly 3 comprises two lateral rollers 5, and the two lateral rollers 5 in each roller assembly 3 are respectively rolled and abutted on two sides of the linear guide rail 4. The walking body is prevented from deviating laterally from the track body 100 through clamping and limiting of the two lateral rollers 5. On the basis of the above structure, the track body 100 further comprises a rack 6 arranged in parallel with the linear guide rail 4, and the roller assembly 3 further comprises a walking gear 7, a supporting wheel 8 and a lateral adjusting component. The output end of the driving motor 2 is connected with the walking gear 7 in one of the two groups of roller assemblies 3, or the driving motor 2 has two driving motors 2, and the two driving motors 2 are respectively connected with the walking gears 7 in the two groups of roller assemblies 3. The walking gear 7 is engaged with the rack 6. The driving motor 2 drives the walking gear 7 to move along the rack 6, so as to realize movement of the walking mechanism of the stacker along the track body 100. The supporting wheel 8 is laterally movably installed on the walking frame 1 through the lateral adjusting component and is rolled and abutted on the top of the linear guide rail 4, so as to support the weight of the walking mechanism and the stacker.

[0025] In use, the driving motor 2 drives the walking gear 7 to move along the rack 6, and the walking body is prevented from deviating laterally from the track body 100 through the lateral rollers 5. After the walking mechanism of the stacker is installed on the stacker, the supporting wheel 8 is used to support the weight of the stacker. The lateral adjusting component can adjust the lateral position of the supporting wheel 8, so as to ensure alignment with the top of the linear guide rail 4, avoid deflection of the supporting wheel 8, ensure stability of walking of the stacker and ensure bearing capacity.

[0026] In detail, the roller assembly 3 further comprises a movable cover 9, and the supporting wheel 8 is installed in the inside of the movable cover 9. The walking frame 1 is provided with a mounting cavity 10, and the lateral adjusting component comprises a pin shaft 11 and a plurality of adjusting bolts 12. The pin shaft 11 is fixed horizontally between opposite inner walls of the mounting cavity 10, and the extension direction of the pin shaft 11 is perpendicular to the extension direction of the track body 100. In order to ensure stability, the pin shaft 11 can be provided with two or more pin shafts 11, which are respectively arranged on both sides of the axis of the supporting wheel 8. The movable cover 9 is slidably sleeved on the outside of the pin shaft 11, the plurality of adjusting bolts 12 are screwed from the outside of the two sides through the side walls of the mounting cavity 10 and are abutted with the outer side walls of the movable cover 9, and the bottom of the supporting wheel 8 extends out of the movable cover 9 and the mounting cavity 10 and is abutted with the top of the linear guide rail 4.

The plurality of barcodes are arranged along the extension direction of the track body 100. The barcode sensor 14 can be moved to align with any barcode along with the walking frame 1. The barcodes are used to be arranged on the corresponding storage columns of the shelves. When the stacker walking mechanism drives the stacker to the specified storage location, the barcode sensor 14 can detect the barcode, so as to stop the stacker at the specific storage location through the external control device.

[0031] Further, the track body 100 is provided with a stop block 15 at both ends, and the walking frame 1 is provided with a buffer 16 opposite to the stop block 15 at both ends.
