The invention relates to a storage structure, in particular to a storage system and its application method.

According to the increasing cost of land acquisition, the current automatic storage equipment is designed in the spirit of using land resources as much as possible, and the automatic storage design that uses the handling trolleys for loading and unloading operations is currently produced. Under this automatic storage structure, when the user performs the warehousing operation, the goods are first placed in an warehousing work area and a storage location is designated, and then an overhead trolley transports the goods to the shelf position specified by the user. Because the overhead trolley is composed of the structure of the base, the column, the upper beam, the lifting platform and the pick-up mechanism, it is bulky and heavy, which also causes the moving of the overhead trolley to be slow, and it is impossible to shorten the time of entering and leaving the warehouse today. Meet the needs of current use.

For the above-mentioned demand for shortening the time of entering and leaving the warehouse, there has been a patent of Japanese Patent No. 2007001765A, which employs two overhead trolleys 4 on one track 7, and then operates the warehousing operation or the delivery operation together by controlling the two overhead trolleys 4. Way to save time. When there are multiple materials in the warehouse, the elevated trolleys 4 can be processed together with the crop materials; when the plurality of materials are discharged from the warehouse, the overhead trolleys 4 are also used for processing the crop materials together, and the operation mode can simultaneously increase the inflow and outbound storage. The quantity of materials increases the efficiency of entering and leaving the warehouse. However, the above patents need to use only one overhead trolley 4 to handle the above situation when carrying out the warehousing operation and the outbound operation at the same time, which is the same as the prior art. In addition, the above patents increase the efficiency of loading and unloading operations by increasing the number of overhead trolleys 4, but it is still unavoidable because of the negative impact of the slow moving of the overhead trolleys, and the efficiency of material loading and unloading operations is limited. Also, it is known from the patent content that these elevated trolleys operate on the same track, which will increase the risk of system operation, such as the collision of overhead trolleys or the damage of one of the overhead trolleys, causing the entire system to be inoperable and also increasing Difficulty in the design of electronic control programs.

In addition, U.S. Patent Publication No. 2008/0226432A1 utilizes an inbound and outbound unit 1 to perform lateral handling work, and an elevator 20 is required to have a vertical height.

Correspondingly, a fourth coordinate P4 and a fifth coordinate P5 are formed. The picking mechanism 11 first moves and aligns with the fourth coordinate P4, and then the transfer mechanism 111 moves and aligns the fifth coordinate P5 to grab the material on the feeding cart 20. After the transfer mechanism 111 obtains the material, the pick-up mechanism 11 moves to align the second coordinate P2, and then the transfer mechanism 111 transfers the material to the third coordinate P3 to store the material in the first storage position S1.

B2) the outbound operation: the overhead trolley 20 moves and aligns with the first coordinate P1, the feeding trolley 20 moves and aligns with the first coordinate P1; the picking mechanism 11 first moves and aligns the second coordinate P2, and then the transfer mechanism 111 moves The third coordinate P3 is aligned to capture the material stored in the first storage position S1. After the transfer mechanism 111 obtains the material, the transfer mechanism 111 transfers the material to the fifth coordinate P5, and then the pick-up mechanism 11 moves and aligns with the fourth coordinate P4, and then is placed on the feeding cart 20, and then the feeding The trolley 20 transfers material to the access area 31 for the user to take.

At the same time, the first vehicle 21 is quickly moved to the side of the overhead trolley 10, and then moved by the pick-up mechanism 11 along the second direction axis Z and the transfer mechanism 111 moves along the third direction axis Y. The transfer mechanism 111 captures the material of the first storage location and places it with the pick-up mechanism 11 after the first vehicle 21, and then transports the material from the first vehicle 21 to an access area 31 for the user to access. Next, the overhead trolley 10 is moved to align with the coordinate formed by the second storage position corresponding to the first direction axis X. At the same time, the second vehicle 22 is quickly moved to the side of the overhead trolley 10, and then moved along the second direction axis Z by the pick-up mechanism 11 and the transfer mechanism 111 moves along the third direction axis Y. The transfer mechanism 111 captures the material in the second storage position and places it in the second vehicle 22 in conjunction with the pick-up mechanism 11, and then transports the material to the access area 31 for the user to access, thereby completing the delivery operation.

If the user wants to simultaneously store the materials to the first storage location and the materials placed in the second storage location. The user first places the material in the access zone 31 in the first vehicle 21, and the second vehicle 22 is an empty vehicle. The first car and the second car start at the same time, and the overhead car 10 first moves to align with the coordinate formed by the first storage position on the first direction axis X. The first vehicle 21 and the second vehicle 22 are quickly moved to the side of the overhead trolley 10, and then moved along the second direction axis Z by the pickup mechanism 11 and the transfer mechanism 111 is along the third direction axis Y. Moving, after the transfer mechanism 111 captures the material and is placed in the first storage position with the pick-up mechanism 11, the storage is completed. Next, the overhead trolley 10 is also moved to align with the coordinates formed by the second storage position corresponding to the first direction axis X. At the same time, the second vehicle 22 is already beside the overhead trolley 10, and then moves along the second direction axis Z by the pickup mechanism 11 and the transfer mechanism 111 moves along the third direction axis Y. The loading mechanism 111 picks up the material and places it with the pick-up mechanism 11 after the second vehicle 22, and then the second vehicle 22 transports the material to the access area 31 for the user to access, and at the same time completes the loading and unloading operation.

It can be seen from the above that the feeding trolleys 20 have materials and empty vehicles respectively, and the overhead trolley 10 is responsible for carrying out the materials of the shelves or loading the materials into the shelves, so that the loading and unloading operations can be performed at the same time.
