The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
The automated guided system according to the embodiment of the present invention includes the pallet 100 and the automated guided vehicle 200 according to the above embodiment, and a process in which the automated guided vehicle 200 carries the pallet 100 is as follows, first, the automated guided vehicle 200 is driven under the pallet 100, and then the jacking device of the automated guided vehicle 200 jacks up so that the bottom plate 10 of the pallet 100 is engaged with the top plate 20 provided on the jacking device, wherein the bottom plate 10 is provided with the positioning hole 11, and the top plate is provided with the positioning protrusion 21 engaged with the positioning hole 11.
A pallet 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 4. The bottom of the shelf 100 is provided with a bottom plate 10, which bottom plate 10 is opposite to the ground. The automated guided vehicle 200 has a top plate 20 that cooperates with the bottom plate 10, the top plate 20 being used to support the pallet 100, wherein the bottom plate 10 is provided with positioning holes 11, and the top plate 20 is provided with positioning protrusions 21. In the lifting process of the vehicle body, the positioning protrusion 21 and the positioning hole 11 are matched with each other to realize the support of the goods shelf 100.
Specifically, as shown in fig. 1, the base plate 10 is provided with at least one positioning hole 11, at least one group of roller assemblies 12 are arranged in the circumferential direction of each positioning hole 11, each roller assembly 12 comprises a roller 121, and the rollers 121 are suspended in the positioning holes 11.
Referring to fig. 7 in combination with fig. 8, in the process of carrying the carrier 100, when the positioning hole 11 and the positioning protrusion 21 have a matching error, the roller assembly 12 may slide down from top to bottom along the surface of the positioning protrusion 21 to adjust the matching relationship between the positioning hole 11 and the positioning protrusion 21, so as to achieve accurate matching between the positioning hole 11 and the positioning protrusion 21, and improve the matching stability of the bottom plate 10 and the top plate 20.
Wherein, the horizontal distance between the two rollers 121 in each roller assembly 12 may be greater than the maximum horizontal distance between the positioning protrusions 21, so that a sufficient adjustment margin between each roller assembly 12 may be ensured, so that the positioning holes 11 are accurately matched with the positioning protrusions 21.
Advantageously, as shown in fig. 8, the horizontal distance of the positioning projection 21 increases gradually from top to bottom. In this way, the positioning protrusion 21 can more smoothly extend into the positioning hole 11, and the roller 121 can smoothly slide downwards along the surface of the positioning protrusion 21, so that the roller assembly 12 can conveniently adjust the matching relationship between the positioning hole 11 and the positioning protrusion 21. The positioning protrusion 21 may be a truncated cone or a regular quadrangular prism.
It will be appreciated that wear of the positioning boss 21 may be reduced as the roller assembly 12 slides over the surface of the positioning boss 21.
In short, according to the pallet 100 of the embodiment of the present invention, at least one set of roller assemblies 12 is disposed in the circumferential direction of the positioning hole 11, and the matching relationship between the positioning hole 11 and the positioning protrusion 21 is adjusted by the roller assemblies 12, so that the wear between the positioning hole 11 and the positioning protrusion 21 is reduced, and the stability of the pallet 100 on the automated guided vehicle 200 is improved.
According to the unmanned carrying system provided by the embodiment of the invention, the roller assemblies 12 capable of adjusting the matching relation between the positioning holes 11 and the positioning protrusions 21 are arranged in the circumferential direction of the positioning holes 11, so that the bottom plate 10 of the goods shelf 100 is stably matched with the top plate of the unmanned carrying vehicle 200, the goods shelf 100 is prevented from tilting on the unmanned carrying vehicle 200, and the stability of the goods shelf 100 on the unmanned carrying vehicle 200 is improved.
In some embodiments of the present invention, the roller assembly 12 may include: two oppositely disposed axle seats 122 and a locating axle 123. Each shaft seat 122 is formed with a shaft hole, two ends of the positioning shaft 123 respectively extend into the shaft holes, and the roller 121 is rotatably sleeved on the periphery of the positioning shaft 123.
