Description

Automated three-dimensional warehouse unit cargo automatic adjustment storage platform and its adjustment method

technical field

The invention relates to the technical field of mechanical storage devices, in particular to an automatic three-dimensional warehouse unit cargo automatic adjustment storage platform and a cargo adjustment method.

Background technique

Automated three-dimensional warehouse, also known as automated three-dimensional warehouse, uses three-dimensional warehouse equipment to realize high-level rationalization of warehouses, automatic access, and simplified operation: automated three-dimensional warehouse is a form with a relatively high level of technology. The main body of the automated three-dimensional warehouse is composed of shelves, roadway stacking cranes, entry (exit) warehouse workbench and automatic entry (exit) and operation control system. The shelf is a building or structure with a steel structure or reinforced concrete structure. The shelf is a standard-sized cargo space. The roadway stacking crane walks through the roadway between the shelves to complete the work of depositing and picking up goods.

The roller-type or chain conveyor-type storage platform is one of the main equipments of the front-end conveying system of the automated three-dimensional warehouse. It is located at the front end of the conveying system in front of the warehouse. Connected with the conveying trolley, when the unit goods are put into the warehouse, the assembled unit goods are usually placed on the storage platform by using a forklift. After passing the size and weight inspection, they are transferred to the conveying trolley for automatic storage.

FIG. 1 is a schematic structural diagram of a storage platform of a chain conveyor in the prior art. As shown in Figure 1, the existing chain conveyor type storage platform includes a frame 1, a unit cargo conveying chain 2 arranged on both sides of the frame 1, a horizontal fixed baffle 3 arranged on the outside of the unit cargo conveying chain and A fixed stopper 4 arranged laterally at the feeding end of the rack and a gantry-type detection frame 5 for measuring the width and height of the unit goods, the detection frame is provided with a height sensor and a width sensor.

However, the working surface of the storage platform of the existing automated three-dimensional warehouse, that is, the distance between the two horizontal fixed baffles is equal to the width of the pallet. During the actual storage operation, one person usually observes and one person operates the forklift, and it is often necessary to repeatedly adjust the parking space. Aligning the warehousing entrance affects the efficiency of warehousing, and relies too much on the technical level of workers, which greatly increases labor costs.
