[0023] The method for automatically loading, weighing and stacking ore barrels is characterized by comprising the following steps:

[0024] Place multiple empty material barrels on a pallet, and then place the pallet on a circular conveyor line. Each pallet is equipped with an RFID tag with the material barrel information. Pour the sieved large ore into the large ore feed hopper, the medium ore into the medium ore feed hopper, and the ore powder into the powder feed hopper.

[0025] S1: The circular conveyor belt transports the empty material barrels and pallets at the front to the bulk material weighing station and then stops conveying; the RFID read / write head at the bulk material weighing station binds the RFID information on the pallet;

[0026] S2: After the large ore enters the upper conveyor belt from the large ore feed hopper, the different conveying speeds of the multiple upper conveyor belts will pull the large ores on the upper conveyor belts apart. After being conveyed to the large ore distribution plate, the large ore distribution plate rotates, separating the large ores one by one, causing the large ores to fall onto the lower conveyor belt. The large ore is then conveyed to the large ore guide plate through the lower conveyor belt. The large ore guide plate guides the large ore into the empty material bucket. When the weight of the material bucket reaches the preset weight, the RFID read / write head at the bulk material weighing position records the weight of the material bucket to the RFID on the tray corresponding to the material bucket.

[0027] S3: The circular conveyor belt moves forward, and the material barrels and trays filled with large ore are transported forward to the medium-sized material weighing position, and enter S4; at the same time, the empty material barrels and trays at the rear enter the large-sized material weighing position, and S1 and S2 are repeated;

[0028] S4: The RFID read / write head at the medium-block material weighing position is bound to the RFID information on the pallet. After the medium-block ore enters the upper conveyor belt from the medium-block ore feed hopper, multiple upper conveyor belts use the differential speed principle to separate the medium-block ore on the upper conveyor belt. After being conveyed to the medium-block ore dividing plate, the medium-block ore dividing plate rotates to separate the medium-block ore one by one, causing the medium-block ore to fall onto the lower conveyor belt. The medium-block ore is then conveyed to the medium-block ore guide plate through the lower conveyor belt. The medium-block ore guide plate guides the medium-block ore into the material bucket filled with large ore. When the weight of the material bucket reaches the preset weight, the RFID read / write head at the medium-block material weighing position records the weight of the material bucket to the RFID on the pallet corresponding to the material bucket.

[0029] S5: The circular conveyor belt moves forward, and the material barrels and trays filled with large and medium ores are transported forward to the powder material weighing position, and enter S6; the material barrels and trays filled with large ores are transported forward to the medium block material weighing position, and S3 is repeated; at the same time, the empty material barrels at the rear enter the large block material weighing position, and S1 and S2 are repeated;

[0030] S6: The RFID reader / writer head at the powder weighing station binds to the RFID information on the pallet. The powder ore enters the barrel from the powder feed hopper and is conveyed to the powder guide chute by the screw conveyor. From the powder guide chute, it is introduced into the material barrel filled with large and medium ores. When the weight of the material barrel reaches the preset weight, the RFID reader / writer head at the powder weighing station records the weight of the material barrel to the RFID on the pallet corresponding to the material barrel.

[0031] S7: The ring conveyor belt transports the weighed material barrel forward and enters S8; the material barrel and tray filled with large and medium ores are transported forward to the powder material weighing position, and S6 is repeated; the material barrel and tray filled with large ores are transported forward to the medium block material weighing position, and S3 is repeated; at the same time, the empty material barrel at the rear enters the large block material weighing position, and S1 and S2 are repeated;

[0032] S8: The weighed material barrels are transferred to the range of the palletizing robot. The palletizing robot transfers the material barrels to the pallet for palletizing. The RFID reader / writer on the pallet reads the RFID on the pallet and binds the information of the material barrels to the pallet. The empty pallet continues to be transported on the circular conveyor line to the upper barrel position to load the empty material barrels.

[0033] Repeat S1 to S8;

[0034] When the palletizing robot completes palletizing, the AGV will transfer it to the warehouse.

[0035] After adopting the above structure, the automatic barreling, weighing and stacking equipment for ore and the automatic barreling, weighing and stacking method of the present invention respectively feed large ore, medium ore and ore powder through the feeding mechanism, the large ore is transported by the large ore conveying module, the medium ore is transported by the medium ore conveying module, and the ore powder is transported by the powder transmission module. The large ore is first loaded into the empty material barrel, and then supplemented with the medium ore. Finally, the ore powder is accurately weighed to complete the automatic barreling and weighing action. The entire weighing process is monitored by RFID and RFID read-write heads and the control center. After weighing is completed, it is directly transferred to the pallet for stacking by the stacking robot, realizing automatic barreling, weighing and stacking of ore. The entire barreling, weighing and stacking process does not require human participation, can replace manual work, improve work efficiency, reduce work intensity, and improve automated operation.

[0052] The control center is connected to the feeding mechanism 10 , the ore conveying mechanism 20 , the RFID of the weighing mechanism 30 , the roller line 40 and the palletizing robot 62 of the palletizing mechanism 60 .

[0053] The present invention also discloses a method for automatically barreling, weighing and stacking ore, which comprises the following steps:

[0054] Place multiple empty material barrels 31 on a tray 32, and place the tray 32 on a circular conveyor line 41. Each tray 32 is equipped with an RFID tag with information about the material barrel 31. Pour the sieved large ore into the large ore feed hopper 11, the medium ore into the medium ore feed hopper 12, and the ore powder into the powder feed hopper 13.

[0055] S1: The endless conveyor belt 41 transports the front empty material bucket 31 to the bulk material weighing station 411 and then stops transporting; the RFID read / write head of the bulk material weighing station 411 binds the RFID information on the tray 32;

[0056] S2: After the large ore enters the upper conveyor belt 211 from the large ore feed hopper 11, the multiple upper conveyor belts 211 use the differential principle to pull the large ores on the upper conveyor belt apart, and after being conveyed to the large ore distribution plate 213, the large ore distribution plate 213 rotates to separate the large ores one by one, causing the large ores to fall onto the lower conveyor belt 212. The large ore is conveyed to the large ore guide plate 214 by the lower conveyor belt 212. The large ore guide plate 214 guides the large ore into the empty material bucket 31. When the weight of the material bucket 31 reaches the preset weight, the RFID read-write head of the bulk material weighing position 411 records the weight of the material bucket 31 to the RFID on the tray 32 corresponding to the material bucket 31;

[0057] S3; the endless conveyor belt 41 is conveyed forward, and the material barrel 31 and the tray 32 filled with large ore are conveyed forward to the medium block material weighing position 412. At the same time, the empty material barrel 31 at the rear enters the large block material weighing position 411, and S1 and S2 are repeated;

[0058] S4: The RFID read / write head of the medium block material weighing position 412 is bound to the RFID information on the tray 32. After the medium ore enters the upper conveyor belt 221 from the medium ore feed hopper 12, the multiple upper conveyor belts 212 use the differential principle to pull the medium ores on the upper conveyor belt apart. After being conveyed to the medium ore dividing plate 223, the medium ore dividing plate 223 rotates to separate the medium ores one by one, causing the medium ores to fall onto the lower conveyor belt 222. The medium ore is conveyed to the medium ore guide plate 224 through the lower conveyor belt 222. The medium ore guide plate 224 guides the medium ore into the material bucket 31 filled with large ore. When the weight of the material bucket 31 reaches the preset weight, the RFID read / write head of the medium block material weighing position 412 records the weight of the material bucket 31 to the RFID on the tray 32 corresponding to the material bucket 31;

[0059] S5: The endless conveyor belt 41 moves forward, and the material barrel 31 and the tray 32 filled with large and medium ores are conveyed forward to the powder material weighing station 413; the material barrel 31 and the tray 32 filled with large ores are conveyed forward to the medium block material weighing station 412, and S3 is repeated; at the same time, the empty material barrel 31 at the rear enters the large block material weighing station 411, and S1 and S2 are repeated;

[0060] S6: The RFID reader / writer head at the powder weighing station 413 binds to the RFID information on the tray 32. The powder ore enters the barrel 231 from the powder feed hopper 13 and is conveyed to the powder guide trough 233 by the screw conveyor 232. From the powder guide trough 233, it is introduced into the material barrel 31 filled with large and medium ore. When the weight of the material barrel 31 reaches the preset weight, the RFID reader / writer head at the powder weighing station 413 records the weight of the material barrel 31 to the RFID on the tray 32 corresponding to the material barrel 31. The weight of the material barrel 31 filled with powder can be accurate to grams, realizing automatic weighing and loading of ore into the barrel.

[0061] S7: The ring conveyor belt 41 conveys the weighed material barrel 31 forward; the material barrel 31 and the tray 32 filled with large and medium ores are conveyed forward to the powder material weighing position 413, and S6 is repeated; the material barrel 31 and the tray 32 filled with large ores are conveyed forward to the medium block material weighing position 412, and S3 is repeated; at the same time, the empty material barrel 31 at the rear enters the large block material weighing position 411, and S1 and S2 are repeated;

[0062] S8: The weighed material barrel 31 is transferred to the range of the palletizing robot. The palletizing robot 62 transfers the material barrel 31 to the pallet 61 for palletizing. The RFID reader / writer on the pallet 61 reads the RFID on the tray 32 and binds the information of the material barrel 31 to the pallet 61.

[0063] Repeat S1 to S8;

[0064] When the palletizing robot 62 completes the palletizing of the pallets 61 , the pallet 61 is transported to the warehouse by the AGV.

[0065] A buffering platform 50 is further provided on one side of the palletizing robot 62, and the buffering platform 50 is located within the travel range of the palletizing robot 62. When the pallet 61 of the material barrel 31 is palletized and switched with the empty pallet 61, the material barrel 31 can be temporarily placed on the buffering platform 50.

[0066] Inside the annular conveyor line 41, corresponding to the large-block material weighing position 411, the medium-block material weighing position 412, and the powder material weighing position 413, there are large-block material buffer conveyor lines 42, medium-block material buffer conveyor lines 43, and powder material buffer conveyor lines 44. Transfer mechanisms (not shown) are respectively provided between the annular conveyor line 41 and the large-block material buffer conveyor lines 42, medium-block material buffer conveyor lines 43, and powder material buffer conveyor lines 44. These transfer mechanisms enable transfer of material from the large-block material buffer conveyor lines 42, medium-block material buffer conveyor lines 43, and powder material buffer conveyor lines 44 to the material barrels 31 on the annular conveyor line 41. When material barrels 31 on the annular conveyor line 41 accumulate, they can be buffered by the large-block material buffer conveyor lines 42, medium-block material buffer conveyor lines 43, and powder material buffer conveyor lines 44. The material then enters the next process from the buffer lines for restocking and weighing.

[0067] Preferably, the large ore feed hopper 11, the medium ore feed hopper 12 and the powder feed hopper 13 are each funnel-shaped with a wide top and a narrow bottom.

[0068] The large ore conveying module 21 includes four upper conveyor belts 211 and two lower conveyor belts 212. The bottom width of the large ore feeding hopper 11 corresponds to the width of the first upper conveyor belt 211A. The widths of the first upper conveyor belt 211A, the second upper conveyor belt 211B, the third upper conveyor belt 211C and the fourth upper conveyor belt 211D decrease in sequence. The speeds of the upper conveyor belt 211B increase successively, i.e., the transmission speed of the second upper conveyor belt 211B is faster than that of the first upper conveyor belt 211A, the speed of the third upper conveyor belt is faster than that of the second upper conveyor belt, and the speed of the fourth upper conveyor belt is faster than that of the third upper conveyor belt. The large ore distribution tray 213 has a plurality of large tooth grooves 213A corresponding to the particle size of the ore. The bottom of the large ore distribution tray 213 is connected to a motor, which drives the large ore distribution tray 213 to rotate. The large tooth grooves 213A of the large ore distribution tray 213 that match the maximum size of the ore are used to separate the ores one by one. The separated large ores fall into the lower transmission belt 212. The two lower conveyor belts 212 are arranged side by side. One is slow to buffer some ore, and the other is fast to separate the ores using the differential principle, avoiding the accumulation of large ores when changing the material barrel 31. In order to prevent large ores from stacking up and down on the upper conveyor belt 211, a spring wire brush 215 is further provided on the upper conveyor belt 211. The spring wire brush 215 sweeps down the stacked large ores, and the density of the medium ores is reduced before entering the large ore powder tray 213 to separate the large ores.

[0069] The medium ore conveying module 22 includes four upper conveyor belts 221 and two lower conveyor belts 222. The bottom width of the medium ore feeding hopper 12 corresponds to the width of the first upper conveyor belt 221A. The widths of the first upper conveyor belt 221A, the second upper conveyor belt 221B, the third upper conveyor belt 221C and the fourth upper conveyor belt 221D decrease in sequence. The speed of belt 221D increases successively, i.e., the second upper conveyor belt 221B has a faster transmission speed than the first upper conveyor belt 221A, the third faster than the second, and the fourth slower than the third. The medium ore distribution tray 223 has a plurality of middle tooth grooves 223A corresponding to the ore particle size. The bottom of the medium ore distribution tray 223 is connected to a motor, which drives the medium ore distribution tray 223 to rotate. The ore is separated one by one by the middle tooth grooves 223A of the medium ore distribution tray 223, which match the maximum size of the ore. The separated medium ore falls into the lower transmission belt 222. The two lower conveyor belts 222 are arranged side by side, and the lower conveyor belt 222 near the side of the medium ore guide plate 224 is slower than the other. The slower lower conveyor belt 222 can buffer some medium ore. The speed difference between the two lower conveyor belts 222 is used to separate the medium ore, thereby preventing the accumulation of medium ore when the material barrel 31 is changed. In order to prevent the medium ores from stacking up and down when being conveyed by the upper conveyor belt 221, a spring wire brush 225 is further provided on the upper conveyor belt 221. The spring wire brush 225 sweeps off the stacked medium ores, and the large ores enter the medium ore powder tray 223 after the density is reduced to separate the medium ores.

[0070] The powder feed hopper 13 is provided with a low material level alarm to ensure that the barrel 231 of the powder conveying module 23 is always full of powder. Since the screw conveyor 232 is fixed in the barrel 231, the discharge amount can be converted by speed, so that the material barrel can reach the required weight.

[0071] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.

7. A method for automatic barreling, weighing and stacking of ore using the automatic barreling, weighing and stacking equipment for ore according to any one of claims 1 to 6, characterized in that: The following steps are involved: Place multiple empty material barrels on a pallet, and then place the pallet on a circular conveyor line. Each pallet is equipped with an RFID tag with the material barrel information. Pour the sieved large ore into the large ore feed hopper, the medium ore into the medium ore feed hopper, and the ore powder into the powder feed hopper. S1: The circular conveyor belt transports the empty material barrels and pallets at the front to the bulk material weighing station and then stops conveying; the RFID read / write head at the bulk material weighing station binds the RFID information on the pallet; S2: After the large ore enters the upper conveyor belt from the large ore feed hopper, the different conveying speeds of the multiple upper conveyor belts will pull the large ores on the upper conveyor belts apart. After being conveyed to the large ore distribution plate, the large ore distribution plate rotates, separating the large ores one by one, causing the large ores to fall onto the lower conveyor belt. The large ore is then conveyed to the large ore guide plate through the lower conveyor belt. The large ore guide plate guides the large ore into the empty material bucket. When the weight of the material bucket reaches the preset weight, the RFID read / write head at the bulk material weighing position records the weight of the material bucket to the RFID on the tray corresponding to the material bucket. S3: The circular conveyor belt moves forward, and the material barrels and trays filled with large ore are transported forward to the medium-sized material weighing position, and enter S4; at the same time, the empty material barrels and trays at the rear enter the large-sized material weighing position, and S1 and S2 are repeated; S4: The RFID read / write head at the medium-block material weighing position is bound to the RFID information on the pallet. After the medium-block ore enters the upper conveyor belt from the medium-block ore feed hopper, multiple upper conveyor belts use the differential speed principle to separate the medium-block ore on the upper conveyor belt. After being conveyed to the medium-block ore dividing plate, the medium-block ore dividing plate rotates to separate the medium-block ore one by one, causing the medium-block ore to fall onto the lower conveyor belt. The medium-block ore is then conveyed to the medium-block ore guide plate through the lower conveyor belt. The medium-block ore guide plate guides the medium-block ore into the material bucket filled with large ore. When the weight of the material bucket reaches the preset weight, the RFID read / write head at the medium-block material weighing position records the weight of the material bucket to the RFID on the pallet corresponding to the material bucket. S5: The circular conveyor belt moves forward, and the material barrels and trays filled with large and medium ores are transported forward to the powder material weighing position, and enter S6; the material barrels and trays filled with large ores are transported forward to the medium block material weighing position, and S3 is repeated; at the same time, the empty material barrels at the rear enter the large block material weighing position, and S1 and S2 are repeated; S6: The RFID reader / writer head at the powder weighing station binds to the RFID information on the pallet. The powder ore enters the barrel from the powder feed hopper and is conveyed to the powder guide chute by the screw conveyor. From the powder guide chute, it is introduced into the material barrel filled with large and medium ores. When the weight of the material barrel reaches the preset weight, the RFID reader / writer head at the powder weighing station records the weight of the material barrel to the RFID on the pallet corresponding to the material barrel. S7: The ring conveyor belt transports the weighed material barrel forward and enters S8; the material barrel and tray filled with large and medium ores are transported forward to the powder material weighing position, and S6 is repeated; the material barrel and tray filled with large ores are transported forward to the medium block material weighing position, and S3 is repeated; at the same time, the empty material barrel at the rear enters the large block material weighing position, and S1 and S2 are repeated; S8: The weighed material barrels are transferred to the range of the palletizing robot. The palletizing robot transfers the material barrels to the pallet for palletizing. The RFID reader / writer on the pallet reads the RFID on the pallet and binds the information of the material barrels to the pallet. The empty pallet continues to be transported on the circular conveyor line to the upper barrel position to load the empty material barrels. Repeat S1 to S8; When the palletizing robot completes palletizing, the AGV will transfer it to the warehouse.
