Description

Automatic Crane Collaborative Dynamic Storage System

This creation involves the access system of warehoused goods.

Arrangement by category is the basic method of traditional warehouse goods collection and distribution management, but the disadvantage is that although the management system specifies and records the storage point where the goods are sorted by category in the warehouse, it cannot absolutely prevent the warehouse staff from storing the goods in the wrong storage point The problem. The warehouse allocates space according to the category of items. When a certain type of goods is received less or taken out more, there will be many vacancies in the space of this category, but it cannot be placed for other categories of goods. Or when a certain type of goods is received more and the original storage space is insufficient, there is no suitable place for the overflowed goods to be stored. Obviously, the system and method of sorting requires more warehouse space, but it cannot use the space efficiently.

The storage and retrieval method of goods also leads to a huge space in the food warehouse but cannot be used effectively. The current storage system uses cranes and forklifts (or stackers) as the main tools for picking and placing goods, especially for extremely heavy or bulky goods. .

As shown in Figure 1, when the crane 1 is used to pick and place the goods 2, the hoisted goods 2 move in the space above the storage workshop, so the height of the storage workshop needs to be increased. The general factory building height is 6 meters, and the factory building using the crane needs to be increased to 10 meters or 12 meters. As shown in Figure 2, when a forklift 3 is used to pick and place goods 2, the storage plant must reserve a spacious passage 4 for the operation and rotation of the forklift, and the passage area of the storage plant is usually larger than the area for storing goods.

In order to solve the above problems, this creation proposes an automated crane collaborative dynamic storage system.
