By providing the elongated hole 151, when the storage plate 120 is moved to the arc sections at both ends, the fastening member 160 can slide in the elongated hole 151, so as to ensure that the storage plate 120 can complete the turning motion.

In this embodiment, the material of the storage location plate 120 is preferably a galvanized steel plate with a thickness of 1mm, the upper surface is attached with staggered line protrusions to increase the friction force, and the lower surface is smooth to facilitate the movement on the roller.

The warehouse management system is connected with the shelves through wireless communication technology, such as zigbee. Because the goods stop to receive the inertia effect and need just can stop through the buffering, can stably stop at the goods shelves port according to atress analysis goods in the junction change speed in goods shelves arc region and sharp region. In order to ensure that the goods and the tray do not move relatively when stopping, under the condition that the goods are delivered out of the warehouse, the goods shelf starts to decelerate when the goods delivered out of the warehouse are conveyed to the intersection point of the arc-shaped track and the linear track, and the goods shelf stops completely when reaching the goods outlet.

In this embodiment, each layer of shelf unit is provided with a radio frequency module at the outlet, the radio frequency module can be fixed inside the shelf beam, the center of each storage plate 120 is provided with an electronic tag, and the radio frequency module transmits a radio frequency signal and is connected with the control chip of each layer of shelf unit through a wire.

The principle of the storage plate 120 in the rotary shelf 100 of the utility model is as follows: when goods need to go in and out of the shelf, the control system sends out specific storage position signals which are required to be stored by the goods, the goods shelf receives information, the control chip controls the layer of goods shelf units to rotate, and in the rotating process of the goods shelf, the radio frequency module can identify radio frequency electric waves reflected by the electronic tags on different storage position plates 120. When the radio frequency module identifies the target warehouse location plate 120, the radio frequency module sends a digital signal to the control center, the control chip immediately makes a response, the rotation of the shelf unit is stopped, the goods can be stopped at the port, and the vehicle loading hoister 200 can load the goods into the shelf.

The warehousing process of the stereoscopic warehouse is as follows:

after the truck stops at a platform, goods are placed on the telescopic conveying device 600 in a single piece mode, the goods reach the warehousing coded disc manipulator 710 through the telescopic conveying device 600, the warehousing coded disc manipulator 710 scans the goods and sucks the goods from the telescopic conveying device 600 to a coded disc area (an empty tray is arranged on the coded disc area and is in a static state) on the warehousing conveying line 520, warehousing operation is carried out, and the coded disc and information input of the goods are carried out at the same time; the manipulator stacks the goods reasonably according to the overall dimension of the goods and judges whether the goods are stacked, the warehousing conveying line 520 drives the trays to the main conveying line 510 after the stacking is completed, and the warehousing coded disc manipulator 710 absorbs the next empty tray to the coded disc area on the warehousing conveying line 520 to wait for the next goods loading operation.

The pallets loaded with goods flow to the shelves through the main conveying pipeline 510, the warehouse management system sends shelving information (shelf numbers) to the controller of the pipeline area, the controller opens the photoelectric switch corresponding to the pipeline unit 511 at the front crossing of the shelves according to the shelf numbers received, when the goods are detected, the goods are judged to be the current shelf goods, the belt of the pipeline unit 511 at the crossing is lifted at the moment, the goods are driven to turn (meanwhile, the controller in the pipeline area sends a fork goods instruction to the elevator 200), and the goods reach the chain guide rail conveyor at the shelving crossing.

At this time, the elevator 200 has received the fork goods instruction, the fork extends into the gap at the lower end of the tray, the rotary shelf 100 starts to operate at this time, the rotary shelf is rotated out of the empty warehouse location, the fork retracts into the shuttle rack, and the elevator 200 is started and lifted to the corresponding goods layer. After the goods reach the corresponding goods layer, the goods are sent out by the fork, and the goods are moved to the storage position in the goods shelf. After the goods are placed, the RFID scanner attached to the fork scans the RFID label on the storage position, and the information binding of the goods and the storage position, namely the dynamic binding of the goods and the placement position of the tray, is realized. The fork retracts into the elevator 200, the elevator 200 descends to the upper rack opening, one-time operation is completed, and the next operation is waited.

The ex-warehouse process is as follows:

when the goods are delivered out of the warehouse, the elevator 200 rises to a goods layer where the goods on the lower shelf are located, meanwhile, the warehouse management system sends an instruction to the rotary type goods shelf 100, the corresponding goods lattice is transferred out according to the principle that the first-in first-out is the highest priority, the first-out of the tray which is not full is the second priority, the first-out of the goods close to the goods outlet is the third priority, the elevator 200 stretches out the fork to take the tray, retracts into the elevator 200, and the elevator 200 descends to the goods outlet.

After the goods arrive at the opening of the lower rack, the forks move the goods of the whole pallet to the chain guide rail conveyor outside the lifting frame, the first mechanical arm 400 sucks the goods to the main conveying line 510 in a single piece mode according to the quantity required by the truck list, and the goods flow through the main conveying line 510 to move to the delivery conveying line 530. After the goods reach the delivery port of delivery conveyor 530, AGV back-picks up empty tray to the delivery port other delivery code wheel manipulator 720 limit from empty tray placing area (spare goods area) this moment, and delivery code wheel manipulator 720 carries out the code wheel operation according to algorithm design, and after the code wheel finishes, AGV transport goods to the spare goods district.

When the AGV carries goods to the stock area, the principle that the goods of first-out are swung to the position close to the outer ring is needed, so that the problem that the goods in the inner layer cannot be carried out due to insufficient turning space when the forklift carries the goods to the platform can be avoided.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or that equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention, which is claimed.
