[0002] Warehousing technology and management are key links in the modern logistics system. Their development is closely linked to social economy and scientific and technological progress. In recent years, with the rapid development of emerging technologies such as the Internet of Things, big data, and artificial intelligence, warehousing technology has moved towards intelligence. The Internet of Things technology installs sensors on goods, shelves, equipment, etc. to achieve real-time perception and collection of information such as the storage environment and cargo status; big data technology analyzes a large amount of storage data, explores potential value, and provides support for decision-making; artificial intelligence technology is applied to the path planning, intelligent sorting, inventory forecasting, etc. of storage robots, so that the storage system has higher intelligent decision-making and autonomous execution capabilities. In the warehousing process, the outer packaging of objects needs to be unpacked.

[0003] The existing automatic bag unpacking device can only realize the automatic unpacking of standard sealed bags, has high requirements on the packaging material and the quantity of materials inside the packaging, and is not universal. As a result, the traditional bag unpacking device can only unpack soft-structured woven bags. However, since there may be metal structures in the woven bags, the traditional bag unpacking device may make the woven bags with metal structures difficult to unpack during the unpacking process, resulting in problems such as damage to the equipment. Therefore, the traditional bag unpacking device has limitations.

[0004] After searching, it is found that a bag unpacking device (publication number: CN115489831A) is disclosed in Chinese patent literature. The present application provides a bag unpacking device, which includes a grabbing and transporting mechanism, a bag cutting mechanism and a tilting mechanism. The grabbing and transporting mechanism is used to grab and move the material bag, and the bag cutting mechanism is arranged on one side of the grabbing and transporting mechanism, and is used to perform lateral movement to cut the material bag grabbed and moved by the grabbing and transporting mechanism. After the bag cutting mechanism completes the bag cutting operation, the cut bag mouth is held by the grabbing and transporting mechanism, and the cut bag falls freely. The tilting mechanism includes a receiving plate and a driving member. The receiving plate is arranged below the bag cutting mechanism. The receiving plate is used to receive the free-falling bag and tilt it through the driving of the driving member so that the items in the bag are dumped out and separated from the bag. In the above manner, the bag unpacking device provided by the present application can automatically complete the material bag conveying, positioning, grabbing and unpacking, and separation of inner and outer bags, which greatly reduces the labor intensity of human labor, saves the labor cost, and reduces the secondary contamination of the powder by manual operation. However, the following defects still exist:

[0005] Although the above-mentioned bag unpacking device can automatically complete the material bag conveying, positioning, grabbing and bag unpacking and the inner and outer bag separation, which greatly reduces the labor intensity and saves labor costs, the traditional bag unpacking device can only unpack soft-structured woven bags. However, due to the presence of metal structures in the woven bags, the traditional bag unpacking device may make the woven bags with metal structures difficult to unpack during the unpacking process, resulting in damage to the equipment and other problems.

[0048] By setting the limiting structure 3, woven bags of different sizes can be limited and fixed. All the fixed jaws 302 are driven to rotate by the rotating component until they conflict with the bottom end of the woven bag. After the conflict, the top end of the woven bag conflicts with the bottom end of the elastic conflict band 301. Through double fixation, the fixed limit of the woven bag is completed.

[0053] Principle and process of the present invention:

[0054] First, according to the received control instruction, the output assembly 9 drives the other two synchronous rotation sources to rotate and drive the second connecting arm 7 to move, so that the second connecting arm 7 cooperates with the hinge shaft 8 to drive the first connecting arm 6 to move synchronously, so that the lifting assembly drives the connecting plate 2 to descend to the specified height;

[0055] Secondly, by setting the limiting structure 3, woven bags of different sizes can be limited and fixed, and all the fixed jaws 302 are driven to rotate by the rotating assembly until they conflict with the bottom end of the woven bag. After the conflict, the top end of the woven bag conflicts with the bottom end of the elastic conflict belt 301, and the fixed position of the woven bag is completed through double fixation;

[0056] After that, the output is output again through the output assembly 9, so that the connecting plate 2 rises to a height that matches the cutting tool 10, and drives the connecting plate 2 to move horizontally to above the cutting tool 10, and then resets through the fixed clamp 302, so that the woven bag moves to the top of the cutting tool 10;

[0057] Then, the falling woven bags are unpacked by the cutting tool 10, and the hardware is connected by the transmission hopper 11. At the same time, the materials are transmitted to the top of the transmission container 12 for storage through the transmission hopper 11, and then the transmission container 12 is transported to the designated area by the conveyor belt 13 for the next step;

[0059] Example 2

[0060] See also Figure 1-8 , a hardware automatic bag unpacking device, comprising the following steps:

[0061] S1: After receiving the task of unpacking the hardware, the automatic unpacking device of the hardware prepares for the operation;

[0062] S2: The rotating assembly drives the fixed clamping claw 302 to rotate, thereby completing the position limiting of the woven bag;

[0063] S3: driving the top second connecting arm 7 to rotate through the output assembly 9;

[0064] S4: The second connecting arm 7 cooperates with the first connecting arm 6 to move via the hinge shaft 8;

[0065] S5: The connecting plate 2 with the woven bag positioned thereon is driven by the first connecting arm 6 and the second connecting arm 7 to move upward until it matches the cutting tool 10;

[0066] S6: driving the connecting plate 2 with the woven bag limited therein to move horizontally through the output component 9 until it is above the cutting tool 10;

[0067] S7: Then the rotating assembly drives the fixed clamping claw 302 to reset, so that the woven bag falls above the cutting tool 10, and then the woven bag is cut by the cutting tool 10;

[0068] S8: The material in the woven bag will fall into the top of the transmission hopper 11;

[0069] S9: The conveying hopper 11 discharges the material into the corresponding conveying container 12;

[0070] S10: The transport vessel 12 is transported to one end of the conveyor belt 13 close to the transport robot assembly 16 via the conveyor belt 13;

[0071] S11: Finally, the transfer robot assembly 16 cooperates with the Y-axis adjustment assembly 17, the Z-axis adjustment assembly 18 and the X-axis adjustment assembly 19 to perform command activities and complete the transportation to the next station.

[0072] In S11, the output activities of the transmission robot component 16, the Y-axis adjustment component 17, the Z-axis adjustment component 18 and the X-axis adjustment component 19 will all receive the operation instructions and complete the corresponding activities according to the operation instructions.

[0073] The rotating component drives the fixed clamp 302 to rotate, so that the top of the woven bag is in conflict with the bottom of the elastic conflicting band 301, and after the fixed clamp 302 rotates, it conflicts with the bottom of the woven bag. When the rotating component drives the fixed clamp 302 to rotate, the status of the woven bag is monitored by the monitoring module contained in the automatic bag disassembly of the hardware.

[0074] The monitoring module includes a photoelectric sensor, a proximity sensor and a pressure sensor. The monitoring module completes the status monitoring of the woven bag through the photoelectric sensor, the proximity sensor and the pressure sensor to ensure the lifting and horizontal activity status monitoring of the woven bag.

[0075] The photoelectric sensor emits a light beam through the transmitting end. When the woven bag is in the normal position, the light can reach the receiving end smoothly, and the receiving end generates a corresponding electrical signal. If the woven bag is offset, missing or damaged, the light is blocked or the reflection situation changes, and the light signal received by the receiving end changes, thereby triggering an alarm signal.

[0076] The proximity sensor uses the principles of electromagnetic induction and capacitance change. When the woven bag is close to the sensor at a certain distance, the sensor can detect the presence of the woven bag. A reasonable detection distance range can be set. If the woven bag leaves the range, the woven bag is judged to be in an abnormal state.

[0077] When the pressure sensor is in the normal limit state, it will generate a certain pressure on the pressure sensor, and the sensor will output a stable pressure signal. If the woven bag is damaged, displaced or missing, the pressure will change. The sensor converts the pressure change into an electrical signal change to determine the state of the woven bag.

[0078] In S7, a screening structure is arranged between the bottom of the cutting tool 10 and the top of the conveyor belt 13. The screening structure includes a plurality of screening metal meshes. Through the screening structure, the woven bags produced during the bag unloading process are separated from the materials, allowing the materials to enter the top of the conveying hopper 11.

[0079] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations may be made to the embodiments without departing from the principles and spirit thereof, and the scope of the present invention is defined by the appended claims and their equivalents.
