[0002] Dynamic storage is a storage method that allocates storage units only when needed during program execution and releases them immediately after use. A typical example is the formal parameters of a function. Storage units are not allocated to the formal parameters when the function is defined. They are only allocated when the function is called and released immediately after the function is called.

[0003] Dynamic storage platforms are often used to improve the performance and efficiency of storage devices. Intel's Z87 chipset provides dynamic storage acceleration, which optimizes disk performance and maintains high-efficiency operation in an energy-saving state, thereby improving the performance of SSDs. The device is used in the conveying and packaging process after the filling of bottled products is completed. After the products are filled by the filling line, they are transported by conveying equipment.

[0018] S1: The inlet end of the equipment and the storage area are connected by parallel chain conveyor belts and transferred through guide plates; the storage area is a multiple active storage area of ​​the same form and a ring transfer table connected to expand the capacity;

[0019] S2: A drag chain trolley is set up on the upper and lower sides of the storage platform. The U-shaped chain conveyor belt is circularly inserted on the upper and lower drag chain trolleys. The front and rear ends of the drag chain trolley are respectively set on the storage platform through the drag chain. The front and rear movement of the upper and lower drag chain trolleys on the storage platform can realize the running mileage of the circular chain conveyor belt on the storage platform.

[0020] S3: The upper trolley moves backwards, so as to increase the running mileage of the chain conveyor belt on the conveying platform and increase the storage capacity of the items on the chain conveyor belt on the storage platform; the drag chain trolley realizes the forward and backward movement of the drag chain on the storage platform through the driving motor arranged at the rear end of the storage platform and the drag chain rotating wheel arranged on the motor drive shaft;

The drag chain trolley drags the chain conveyor belt stored under the storage platform from the inlet end of the active storage area to the storage platform.

[0023] S6: When the laser rangefinder detects that the trolley on the storage platform has reached the rear end of the storage platform, the drag chain stops working, and the power of all upstream active storage areas and the chain conveyor belt of the ring transfer platform connected to it resumes working, and the items at the inlet end continue to be transported through the chain conveyor belt, thereby expanding the storage capacity of items on the chain conveyor belt;

[0024] S7: After the faulty equipment is repaired, the faulty equipment is put into operation, and the downstream equipment resumes power operation. The power of all the chain conveyor belts in the upstream active storage areas connected to it stops, the power of the chain conveyor belts in the ring transfer table is restored, and the drag chain rotates in the opposite direction to shorten the running mileage of the chain conveyor belts in the storage area. The chain conveyor belts in the active storage area are retracted from the outlet end to the bottom of the storage table until the upper drag chain trolley moves close to the laser rangefinder, the drag chain stops working, and the power of all chain conveyor belts in the upstream active storage area is restored.

[0025] The beneficial effects of the present invention are as follows: the dynamic storage and transportation platform has a transportation storage area, an adjustable multi-position conveying arc conveyor belt and a corresponding transport vehicle. When equipment failure or shutdown occurs at the downstream end, the import end item transportation can be carried out without stopping. The import end items can be dynamically stored and transported. After the downstream end is restored, the items in the storage area can be gradually transported out, thereby increasing the transportation efficiency during equipment shutdown maintenance.
