[0037] In some embodiments, the automatic unpacking device 100 can further comprise a shaping device 3. The shaping device 3 is arranged in the feeding bin 110 and is used to shape the outer shape of the ton bag 1a, so as to make the outer shape of the ton bag 1a regular, avoid the ton bag 1a with irregular outer shape such as inclination and cone shape affecting the hooking success rate of the hooking device 2 and causing the ton bag 1a to be damaged or other mechanical elements to be damaged due to unstable center of gravity, improve the hooking success rate of the hooking device 2, and improve the safety and reliability of the automatic unpacking device 100.

[0038] The automatic unpacking device 100 can further comprise, but is not limited to, a lifting device 41, a moving device 42, and a bag breaking device 5. The lifting device 41 is arranged in the feeding bin 110 and is independently arranged with the hooking device 2. The lifting device 41 is used to drive the ton bag 1a to move close to or away from the hooking device 2 along the height direction Z of the automatic unpacking device 100. Of course, in other embodiments, the lifting device 41 is connected with the hooking device 2, and the lifting device 41 is used to drive the hooking device 2 to move close to or away from the ton bag 1a along the height direction Z of the automatic unpacking device 100. The bag breaking device 5 is arranged in the bag breaking bin 130 and is used to automatically unpack and feed the ton bag 1a. The moving device 42 is arranged on the top of the cabinet 1 in the height direction Z of the automatic unpacking device 100 and is connected with the hooking device 2. The moving device 42 is used to drive the hooking device 2 to move in the length direction X of the automatic unpacking device 100. Specifically, the moving device 42 is used to drive the hooking device 2 to move between the feeding bin 110 and the bag breaking bin 130.

[0039] In some embodiments, the automatic unpacking device 100 can further comprise a conveying device 43. The conveying device 43 is arranged in the feeding bin 110 and is located below the hooking device 2. The conveying device 43 is used to convey the ton bag 1a to the lifting device 41 or the hooking device 2.

[0040] In some embodiments, the automatic unpacking device 100 can further comprise an air shower device 45. The air shower device 45 is arranged in the feeding bin 110, and the air shower device 45 is used to remove dust and microorganisms adhered to the surface of the ton bag 1a, ensure that the unpacking process of the ton bag 1a is carried out in a clean environment, and thus reduce the risk of material being contaminated.

[0041] In some embodiments, the cabinet 1 is further provided with a bag collecting bin 150. The bag collecting bin 150 is arranged between the feeding bin 110 and the bag breaking bin 130, and is independent of the feeding bin 110 and the bag breaking bin 130. Of course, in some embodiments, the bag collecting bin 150 is integrated with the feeding bin 110, i.e., the bag collecting bin 150 shares a bin body with the feeding bin 110. The automatic unpacking device 100 can further include a bag collecting device 9. The bag collecting device 9 is arranged in the bag collecting bin 150. The bag collecting device 9 is used to recycle the ton bag 1a after the unloading operation. In the embodiments of the present application, the bag breaking device 5 breaks the ton bag 1a, the material is unloaded from the ton bag 1a, and then the hooking device 2 moves the ton bag 1a after the unloading operation to the bag collecting device 9.

In the embodiments of the present application, the dust removal device 47 is in communication with the feeding bin 110, and can absorb the dust separated from the top, the side and the bottom of the ton bag 1a. The dust removal device 47 is in communication with the bag collecting bin 150, and can absorb the dust generated by extruding the ton bag 1a, thereby reducing the dust in the bag collecting bin 150. The dust removal device 47 is in communication with the bag breaking bin 130, and can absorb the dust generated by unloading the ton bag 1a, thereby reducing the dust in the bag breaking bin 130.

[0043] It should be noted that, Figure 1 The purpose of the above description is only to illustrate the arrangement of the cabinet 1 and the hooking device 2, and not to specifically limit the connection position, connection relationship and specific structure of each element. Figure 1 The structure of the automatic unpacking device 100 described above is only illustrative, and does not constitute a specific limitation on the automatic unpacking device 100. In other embodiments of the present application, the automatic unpacking device 100 can include more or fewer elements than those described above. Figure 1More or less components are shown, or certain components are combined, or different components are used, for example, the automatic unpacking device 100 can also include, but is not limited to, an identification device, a gas storage device, a gas spraying device, etc. For example, in the embodiment of the present application, the identification device is arranged on the outside of the cabinet 1. The identification device is used to identify the orientation of the ton bag 1a, so that the lifting lug 12a of the ton bag 1a is aligned with respect to the hooking device 2, thereby improving the success rate of the hooking device 2 hooking the lifting lug 12a. The gas storage device is used to spray compressed gas to different functional areas of the cabinet 1 through the gas spraying device. In the embodiment of the present application, the gas storage device and the gas spraying device cooperate to spray compressed gas to different functional areas of the cabinet 1, which can play a role in dust removal and decontamination. For example, the compressed gas can be air. The gas storage device can also be in communication with the air shower device 45 to spray air into the feed bin 110 through the air shower device 45.

[0044] It should be noted that the ton bag 1a is a large-capacity, heavy-load freight packaging bag used for packaging and transportation, and is usually used for the transportation of solid goods such as granular substances, powdery substances, and blocky substances. The ton bag 1a is used to load materials such as, but not limited to, battery materials, food materials, medical materials, fertilizer materials, and building materials, and the materials loaded in the ton bag 1a are not limited herein. For example, in the embodiment of the present application, the ton bag 1a is used to load battery materials. The battery materials are, for example, but not limited to, positive electrode materials, negative electrode materials, conductive agents, or dispersants, etc. Alternatively, various materials are mixed to form battery mixed materials.

[0045] Please refer to Figure 1 and Figure 2 , Figure 2 is a structural schematic diagram of the ton bag 1a provided by the embodiment of the present application. The ton bag 1a includes a bag body 11a and a lifting lug 12a. In the embodiment, the lifting lug 12a can be arranged on the outer side wall of the bag body 11a. Of course, in some embodiments, the lifting lug 12a can also be arranged at the top of the four corners of the bag body 11a or other positions. The number of the lifting lug 12a can be one or more. For example, in the embodiment, the outer side wall of the bag body 11a is provided with two lifting lugs 12a. The two lifting lugs 12a are symmetrically arranged with respect to the central axis of the ton bag 1a, thereby improving the stress uniformity of the ton bag 1a after being hooked by the hooking device 2.

[0046] The bag body 11a includes an inner bag 111a and an outer bag 112a. The inner bag 111a is located in the inner cavity of the outer bag 112a, and is used to contain the material and directly contact the material. The outer bag 112a is used to bear the weight of the material, and is used to connect with other mechanisms during the transportation of the material. Exemplarily, in an embodiment, the outer bag 112a is made of polyester fiber material, and the inner bag 111a is made of aluminum plastic composite material. The polyester fiber material has the advantages of high strength and good wear resistance, and the use of the polyester fiber material for the outer bag 112a is beneficial to bearing the weight. The use of the aluminum plastic composite material for the inner bag 111a is beneficial to meeting the requirements of moisture-proof, ultraviolet-proof and pollution-proof of the material.

[0047] It can be understood that, if the unloading operation is performed by directly breaking the outer bag 112a, foreign matters generated during the bag breaking process are difficult to avoid mixing into the material, and the foreign matters are generally woven filaments or debris, which are difficult to separate from the material and may affect the normal use of the material in subsequent processes. In order to avoid the above problems, in the embodiment of the present application, the bottom of the outer bag 112a is provided with a discharge port 1120a, and the inner bag 111a is at least partially exposed to the discharge port 1120a. Thus, during the bag breaking process, the bag breaking device 5 can directly break the inner bag 111a through the discharge port 1120a, avoiding damage to the outer bag 112a. Since the inner bag 111a is made of aluminum plastic composite material, it is not easy to generate debris when the inner bag 111a is broken, thereby being beneficial to preventing the woven filaments or debris from falling together with the material.

[0048] In some embodiments, the outer bag 112a is provided with a cover piece (not shown in the figure) at the discharge port 1120a. The cover piece is used to close or open the discharge port 1120a. Thus, on the one hand, the cover piece can protect the inner bag 111a, prevent the inner bag 111a from being broken by the material or being scratched by external obstacles during transportation, and prevent the inner bag 111a from being contaminated; on the other hand, the cover piece can also enhance the bearing capacity of the outer bag 112a when closing the discharge port 1120a. The automatic unpacking equipment 100 further includes a cover piece separating device. During the bag breaking process, the cover piece separating device drives the cover piece to separate from the outer bag 112a to open the discharge port 1120a of the ton bag 1a.

[0049] In some embodiments, the outer bag 112a is provided with a label (not shown in the figure). The label includes at least one of a two-dimensional code, a bar code, a number, a character and a symbol, but is not limited thereto. Exemplarily, in an embodiment, the label is used to identify the material information. The material information includes but is not limited to the material name, the weight, the production date, etc. The label can identify the information carried by the label through an identification device. The identification method is simple and reliable, and the cost is low. In addition, the label itself can also be used to identify other information, realizing the reuse of the label.

[0050] The lug 12a comprises a plurality of fixing portions 121a and at least one hooking portion 122a. Each hooking portion 122a is connected between two adjacent fixing portions 121a, and the extending direction of the fixing portions 121a intersects the extending direction of the hooking portion 122a. When the hooking portion 122a is provided in a plurality, two fixing portions 121a between two adjacent hooking portions 122a are provided in a stacked manner. In this way, the fixing portions 121a can enhance the connection strength between the lug 12a and the bag body 11a, and improve the reliability and safety of the automatic unpacking equipment 100. Of course, in some embodiments, the hooking portion 122a can also be provided as one. Exemplarily, in the present embodiment, each lug 12a is configured in an M-shaped structure, so that the structure is simple, easy to process and manufacture, and the ton bag 1a is more uniform after being hooked by the hooking device 2, so that the bag breaking device 5 can more accurately break the ton bag 1a.

[0051] It can be understood that the longer the length of the hooking portion 122a, the more likely the hooking portion 122a will sag and shift, thereby reducing the success rate of the hooking device 2 hooking the lug 12a. In the present embodiment, the length of the hooking portion 122a is substantially equal to the distance between the two adjacent fixing portions 121a, so that the hooking portion 122a abuts against the bag body 11a, thereby improving the success rate of the hooking device 2 hooking the lug 12a. Of course, in some embodiments, the length of the hooking portion 122a can also be greater than the distance between the two adjacent fixing portions 121a, and the present embodiment is not limited in particular.

[0052] Please refer to Figure 1 and Figure 3 , Figure 3 is Figure 1 the structure diagram of the hooking device 2 of the automatic unpacking equipment 100 in

[0053] In some embodiments, the hooking device 2 further comprises a sealing cover 250. The translation driving member 220 is arranged inside the sealing cover 250. Thus, the sealing cover 250 can seal the translation driving member 220 arranged on the mounting base 210. On the one hand, the dust generated during the bag breaking process cannot enter the movement hinge of the translation driving member 220, which enhances the movement reliability and connection stability of the translation driving member 220 relative to the mounting base 210, avoids the movement wear problem of the mechanical structure movement component due to the entry of the material dust, and prolongs the service life. On the other hand, the metal powder and debris generated due to the movement wear of the translation driving member 220 and the mounting base 210 cannot enter the material, which avoids the material pollution and meets the product quality and environmental protection requirements.

[0054] For the sake of accuracy of description, all the directions involved herein are in the direction of Figure 1 and Figure 3 reference, the "length direction X" refers to the direction in which the moving device 42 drives the ton bag 1a to move relative to the cabinet 1, that is, the left-right direction in Figure 1 (the positive direction of the X axis is right); the term "width direction Y" refers to the opening and closing direction of the two hooking assemblies in the hooking device 2, that is, the front-rear direction in Figure 3 (the positive direction of the Y axis is rear); the term "height direction Z" refers to the direction in which the lifting device 41 drives the ton bag 1a to lift, that is, the up-down direction in Figure 1 (the positive direction of the Z axis is up), wherein the length direction X, the width direction Y and the height direction Z together constitute three orthogonal directions of the automatic unpacking equipment 100. The length direction X, the width direction Y and the height direction Z of the automatic unpacking equipment 100 can be customized according to the specific structure of the product and the perspective of the drawing, which is not limited in the present application. For the convenience of description, the up, down, left, right, front, back and other directions in the present application are relative positions, which do not constitute a limitation of implementation. Among them, the length direction X of the hooking assembly 230 is parallel to the length direction X of the hooking device 2 and the length direction X of the automatic unpacking equipment 100, the width direction Y of the hooking assembly 230 is parallel to the width direction Y of the hooking device 2 and the width direction Y of the automatic unpacking equipment 100, and the height direction Z of the hooking assembly 230 is parallel to the height direction Z of the hooking device 2 and the height direction Z of the automatic unpacking equipment 100.

[0055] Please refer to Figure 3 and Figure 4 , Figure 4 are Figure 3FIG. 1 is a structural schematic diagram of a first perspective view of the hooking assembly 230 of the hooking device 2 in the application. The hooking assembly 230 comprises a frame 21, a hook 23, a limiting piece 24, and a first driving piece 25. The hook 23 is installed on the frame 21 and is used for hooking the lifting lug 12a of the ton bag 1a. The limiting piece 24 is rotatably installed on the frame 21. The first driving piece 25 is in driving connection with the limiting piece 24, and the first driving piece 25 is used for driving the limiting piece 24 to rotate so as to lock the lifting lug 12a between the limiting piece 24 and the hook 23; or, to push the lifting lug 12a away from the hook 23.

[0056] The hooking assembly 230 provided by the embodiment of the application, on the one hand, adopts the hook 23 to hook the lifting lug 12a of the ton bag 1a, thereby avoiding the problem that the existing hook 23 adopts the mode of piercing the ton bag 1a to hook the ton bag 1a, which causes damage to the woven bag and even causes the woven debris to pollute the material, and improves the quality of the material. On the other hand, the automatic anti-unhooking and automatic unhooking functions of the lifting lug 12a of the ton bag 1a are realized based on the rotation of the limiting piece 24, and the hook 23 does not need to be provided with an additional driving structure and transmission structure, thereby improving the integration degree of mechanical parts, reducing the number and weight of parts, reducing the assembly difficulty, and being simple and compact in structure, small in occupied space, and low in cost. On the other hand, manual participation in unpacking is not needed, and the working efficiency and use safety of the automatic unpacking equipment 100 are improved.

[0057] Understandably, after the hook 23 hooks the lifting lug 12a of the ton bag 1a, the first driving piece 25 drives the limiting piece 24 to rotate in a first direction, so as to lock and maintain the lifting lug 12a between the hook 23 and the limiting piece 24. Specifically, the limiting piece 24 and the hook 23 enclose a limiting space for limiting the lifting lug 12a, thereby preventing the problem of unhooking of the lifting lug 12a. After the ton bag 1a is unloaded, the first driving piece 25 drives the limiting piece 24 to rotate in a second direction, so as to push the lifting lug 12a away from the hook 23 by the limiting piece 24, thereby realizing unhooking of the ton bag 1a and facilitating subsequent recycling operation of the ton bag 1a. The first direction is opposite to the second direction.

[0058] In the embodiment, the limiting piece 24 comprises a rotating shaft 241 and a limiting rod 242. The rotating shaft 241 is rotatably installed on the rack 21 and is in transmission connection with the first driving piece 25. The limiting rod 242 is fixedly connected with the rotating shaft 241, and the limiting rod 242 is arranged close to the hook 23. In the projection plane perpendicular to the central axis of the rotating shaft 241, the free end of the hook 23 is located in the swing range of the limiting rod 242. Thus, on the one hand, the rotating shaft 241 is driven to rotate based on the driving piece to drive the limiting rod 242 to swing, thereby reducing the occupied space of the limiting piece 24 to the rack 21 and improving the compactness of the overall structure of the hooking assembly 230. On the other hand, in the projection plane perpendicular to the central axis of the rotating shaft 241, the free end of the hook 23 is located in the swing range of the limiting rod 242, thereby improving the success rate of the limiting rod 242 in locking and pushing away the lug 12a. Of course, in some embodiments, the rotating shaft 241 can be omitted, that is, the limiting piece 24 comprises the limiting rod 242, and the first driving piece 25 is directly used to drive the first driving piece 25 to rotate.

[0059] Please refer to Figure 4 and Figure 5 , Figure 5 is Figure 3 the second perspective view of the hooking assembly 230 of the hooking device 2 in

[0060] The two ends of the rotating shaft 241 are rotatably connected to the rack 21, thereby improving the stability of the rotation of the limiting piece 24 relative to the rack 21. Of course, in some embodiments, one end of the rotating shaft 241 is rotatably connected to the rack 21, and the other end of the rotating shaft 241 is connected to the limiting rod 242. Alternatively, the rotating shaft 241 is independently arranged with the rack 21 and is directly connected with the first driving piece 25.

[0061] In some embodiments, the limiting piece 24 further comprises a bearing 245. The bearing 245 is fixedly installed on the rack 21, and the rotating shaft 241 penetrates the bearing 245. Thus, on the one hand, the bearing 245 can improve the smoothness and stability of the rotation of the rotating shaft 241 relative to the rack 21. On the other hand, the bearing 245 can support the rotating shaft 241, reduce the friction between the bearing 245 and the rack 21, reduce the friction and wear, thereby prolonging the service life of the mechanical equipment and improving the operation efficiency.

[0062] The first driving member 25 is arranged one and connected to one end of the rotating shaft 241. Thus, the number of components is reduced, the cost is saved, and the overall structure of the hooking assembly 230 is more compact. In some embodiments, the first driving member 25 can also be arranged in multiple, for example, the first driving member 25 is arranged two, and the two first driving members 25 are respectively connected to the two ends of the rotating shaft 241. For example, one of the first driving members 25 is used to drive the rotating shaft 241 to rotate forward, and the other first driving member 25 is used to drive the rotating shaft 241 to rotate reversely; or, the two first driving members 25 work alternately. On the one hand, it avoids that one of the first driving members 25 abnormally causes the limiting member 24 and the hook 23 to be unable to lock and unlock the lifting belt of the ton bag 1a; on the other hand, the two first driving members 25 working alternately can reduce the running time of a single first driving member 25, thereby reducing the heating and loss of the first driving member 25, and prolonging the service life of the first driving member 25.

[0063] In the embodiment, the first driving member 25 is arranged on the outer side wall of the rack 21, so as to facilitate the assembly, maintenance and replacement of the first driving member 25; on the other hand, it avoids the interference between the first driving member 25 and the hook 23 or the limiting member 24 or other components, optimizes the overall layout of the hooking assembly 230, and realizes miniaturization and lightweight design. Of course, the first driving member 25 can also be arranged inside the rack 21 according to actual conditions.

[0064] The limiting rod 242 is configured as an arc-shaped rod or a straight rod. Thus, on the one hand, under the same force, the arc-shaped rod is more easily deformed than the straight rod, so that the arc-shaped rod can reduce the friction between the limiting rod 242 and the ton bag 1a and the rack 21 when the limiting member 24 rotates, and avoid the problem that the limiting rod 242 scratches the ton bag 1a or the rack 21 to generate debris; on the other hand, the straight rod is convenient for processing and manufacturing, and when the ton bag 1a is in a locked state, since the straight rod is less likely to be deformed than the arc-shaped rod, the lifting lug 12a of the ton bag 1a can be more firmly locked between the limiting member 24 and the hook 23. Exemplarily, in the embodiment, the limiting rod 242 is configured as an arc-shaped rod.

[0065] In some embodiments, the free end of the limiting rod 242 away from the rotating shaft 241 is provided with a circular arc structure 2421, so as to avoid the problem that the limiting rod 242 scratches the ton bag 1a or the rack 21 to generate debris or damage the ton bag 1a.

[0066] In the embodiment, the hook 23 comprises a connecting rod 231 and two hook bodies 232. The connecting rod 231 is fixedly connected with the two hook bodies 232 and forms a position-avoiding groove 2301. The limiting rod 242 is rotatably arranged in the position-avoiding groove 2301. In this way, on the one hand, based on the fact that the limiting rod 242 is rotatably arranged in the groove, the two hook bodies 232 can provide limiting and guiding effects for the swing of the limiting rod 242, thereby improving the success rate of the limiting rod 242 in locking and pulling off the lug 12a. On the other hand, the two hook bodies 232 are connected into an integrated structure through the connecting rod 231, which facilitates assembly, improves the overall structural strength of the hook 23, prolongs the service life of the hook 23, and improves the success rate of the hook 23 in hooking the lug 12a.

[0067] Of course, in some embodiments, the hook 23 can also comprise one hook body 232 or a plurality of hook bodies 232. When the hook body 232 is provided as one, the hook 23 abuts against the limiting rod 242 to avoid the problem of unhooking from the gap between the lug 12a and the limiting rod 242 and the hook 23. When the hook body 232 is provided as a plurality, the limiting rod 242 can be arranged in intervals with the hook body 232, thereby reducing the friction between the limiting rod 242 and the hook 23 and improving the smoothness and reliability of the swing of the limiting rod 242 in the position-avoiding groove 2301. The two adjacent hook bodies 232 are fixedly connected with the connecting rod 231 and form a position-avoiding groove 2301. Each position-avoiding groove 2301 is provided with a limiting piece 24, thereby improving the locking force and peeling force of the limiting piece 24 on the lug 12a.

[0068] The hook 23 and the limiting rod 242 are each provided as at least two. The at least two limiting rods 242 are arranged in intervals on the rotating shaft 241 and are respectively arranged in one-to-one correspondence with the hook 23. In this way, on the one hand, based on the fact that a plurality of hooks 23 are provided, the plurality of hooks 23 can disperse the weight of the ton bag 1a, can reduce the pressure borne by each hook 23, thereby prolonging the service life of the hook 23 and reducing the risk of breakage of the hook 23, and the plurality of hooks 23 can provide a plurality of support points, thereby improving the stability of the ton bag 1a and the accuracy of subsequent piercing. On the other hand, each hook 23 cooperates with the corresponding limiting rod 242, thereby realizing the functions of automatic locking and automatic unhooking of the lug 12a of the ton bag 1a, thereby improving the working efficiency and use safety of the automatic unpacking equipment 100.

[0069] Of course, in some embodiments, the number of limit rods 242 can also be more than the number of hooks 23. The plurality of limit rods 242 are arranged at intervals on the rotating shaft 241. For example, one hook 23 can correspond to two or three limit rods 242, thereby improving the locking force and peeling force of the limiting piece 24 on the lifting lug 12a. It should be noted that the number of hooks 23 and limit rods 242 can be set according to the load bearing capacity of the hook 23, the size of the ton bag 1a, and other factors, and the embodiments of the present application are not limited.

[0070] The hook 23 further comprises a guide sliding structure 234, which is configured as an arc surface arranged at the free end of the hook 23; or a rolling structure connected with the free end of the hook 23 in a rolling manner. In this way, the friction between the hook 23 and the ton bag 1a is reduced, and the problem of the hook 23 scratching the ton bag 1a and generating debris when hooking the lifting lug 12a is avoided. Exemplarily, in the present embodiment, the free ends of the two hook bodies 232 of the hook 23 are configured as arc surfaces.

[0071] In some embodiments, the hooking assembly 230 further comprises a position sensor 26 installed on the rack 21 and used to generate a sensing signal when detecting that the ton bag 1a reaches the hooking position. In this way, when it is detected that the ton bag 1a reaches the hooking position, it indicates that the hook 23 is in contact with the ton bag 1a, thereby improving the success rate of the hook 23 hooking the lifting lug 12a of the ton bag 1a and improving the use safety of the automatic unpacking equipment 100. The position sensor 26 can be, but is not limited to, an optical encoder, a magnetic encoder, a laser ranging sensor, an ultrasonic sensor, etc.

[0072] The position sensor 26 and the hook 23 are arranged at intervals in the length direction X of the hooking assembly 230. In this way, on the one hand, the problem of damage to the position sensor 26 caused by arranging the position sensor 26 on the hook 23 is avoided, and the service life of the position sensor 26 is prolonged; on the other hand, the position sensor 26 and the hook 23 are independently arranged on the rack 21, thereby facilitating the assembly, maintenance and replacement of the position sensor 26 and the hook 23.

[0073] In the embodiment, the mounting rack 215 is arranged on the rack 21, and the in-place sensor 26 is mounted on the mounting rack 215. The mounting rack 215 is detachably connected with the rack 21. In some embodiments, the mounting rack 215 is pivotally connected with the rack 21, so that when the ton bag 1a presses the in-place sensor 26, the mounting rack 215 rotates relative to the rack 21, thereby reducing the risk of the ton bag 1a crushing the in-place sensor 26 during the process of the hook 23 hooking the ton bag 1a, and prolonging the service life of the in-place sensor 26. The mounting rack 215 can be configured as a triangular rack, thereby improving the structural degree and stability of the mounting rack 215, reducing the weight, and saving the cost. Of course, in some embodiments, the mounting rack 215 can also be fixedly connected with the rack 21, and the mounting member can also be configured as other shapes, such as L-shaped, square, etc.

[0074] Please refer to Figure 4 and Figure 6 , Figure 6 is Figure 3 the third perspective view of the hooking assembly 230 of the hooking device 2 in

[0075] The hook 23 comprises an abutting surface 2302 and a connecting surface 2303. The abutting surface 2302 and the connecting surface 2303 are oppositely arranged in the width direction Y of the hooking assembly 230. The abutting surface 2302 is used to abut against the ton bag 1a. The in-place sensor 26 is located between the abutting surface 2302 and the connecting surface 2303 in the projection plane parallel to the width direction Y of the hooking assembly 230. The distance between the in-place sensor 26 and the abutting surface 2302 is less than or equal to a preset threshold. Thus, when the distance between the in-place sensor 26 and the abutting surface 2302 approaches zero, the in-place sensor 26 is arranged substantially flush with the hook 23 in the projection plane parallel to the width direction Y of the hooking assembly 230, thereby improving the detection accuracy of the in-place sensor 26. When the distance between the in-place sensor 26 and the abutting surface 2302 approaches zero, the in-place sensor 26 is retracted by a distance from the hook 23 in the projection plane parallel to the width direction Y of the hooking assembly 230, thereby avoiding the problem that the hook 23 is pressed against the ton bag 1a when hooking the ton bag 1a, prolonging the service life of the in-place sensor 26, and ensuring the detection accuracy of the in-place sensor 26. The preset threshold can be, but is not limited to, 0.5 cm, 1 cm, 2 cm, etc., and the embodiments of the present application are not limited in this regard.

[0076] In some embodiments, the height difference between the in-place sensor 26 and the free end of the hook 23 in the height direction Z of the hooking assembly 230 is within a preset height range. Thus, it can be understood that the smaller the height of the in-place sensor 26 and the free end of the hook 23 in the height direction Z, the higher the detection accuracy of the in-place sensor 26, thereby improving the success rate of the hook 23 hooking the lifting lug 12a, and improving the working efficiency and use safety of the hooking assembly 230.

[0077] Exemplarily, in the present embodiment, the rack 21 comprises two side beams 211 and a cross beam 212. The cross beam 212 is connected between the two side beams 211. The hook 23 is mounted on the cross beam 212, and the limiting piece 24 is rotatably mounted on the side beam 211. Thus, interference between the limiting piece 24 and the hook 23 is avoided, and the overall structural compactness of the hooking assembly 230 is improved. The cross beam 212 is fixedly connected with the two side beams 211. The cross beam 212 and the two side beams 211 can be detachably connected or integrally formed. The cross beam 212 and the side beams 211 can improve the structural strength of the rack 21, and can absorb and disperse the force of the ton bag 1a, thereby improving the use safety of the automatic unpacking equipment 100. Specifically, the hook 23 and the in-place sensor 26 are suspended from the bottom wall of the cross beam 212, thereby facilitating assembly and positioning the mounting position of the hook 23 relative to the rack 21, thereby avoiding interference between the rack 21 and the rack 21 when hooking the ton bag 1a. Of course, in some embodiments, the rack 21 can be configured as a plate body or a block structure, and the present application is not limited in this regard.

[0078] In some embodiments, the rack 21 further comprises a protective cover 216. The protective cover 216 is fixedly connected with the cross beam 212 and / or the two side beams 211, and forms the mounting cavity 2101 with the cross beam 212 and the two side beams 211. The hook 23 and the limiting member 24 are arranged in the mounting cavity 2101, and the protective cover 216 comprises a cover body 2161 and a protective plate 2162 fixedly connected with the cover body 2161, the protective plate 2162 covers the cross beam 212, and a top wall of the protective plate 2162 is configured as an inclined surface. In this way, on the one hand, the protective cover 216 can prevent foreign matter or other impurity particles from entering the mechanical parts in the protective cover 216 and affecting the operation, and prevent the debris generated in the mechanical parts in the protective cover 216 from entering the material and affecting the quality of the material; on the other hand, the top wall of the protective plate 2162 is configured as an inclined surface, so that the accumulated material on the protective plate 2162 can slide under the action of gravity, thereby avoiding the accumulation of material on the rack 21 and improving the dust removal effect. In the present embodiment, the protective cover 216 is fixedly installed on the rack 21. Specifically, the edges of the protective cover 216 are detachably installed on the cross beam 212 and the two side beams 211 through locking structures, thereby improving the reliability and stability of the connection between the protective cover 216 and the rack 21.

[0079] In some embodiments, the hooking assembly 230 further comprises a weight sensor 28. The weight sensor 28 is arranged between the rack 21 and the hook 23. Specifically, the weight sensor 28 is arranged between the connecting rod 231 and the rack 21. In this way, on the one hand, the weight sensor 28 can be used to detect whether the hook 23 hooks the lifting lug 12a of the ton bag 1a, thereby improving the reliability and safety of the hooking assembly 230 hooking the ton bag 1a; on the other hand, the weight sensor 28 can also be used to detect the residual amount of the material in the ton bag 1a when the ton bag 1a is broken and discharged. Specifically, in some embodiments, the weight sensor 28 can also be arranged on the hook body 232 of the hook 23.

[0080] In some embodiments, the rack 21 is provided with a sliding rail 214, and the hook 23 is provided with a guide structure 235 that slidably cooperates with the sliding rail 214, and the extension direction of the sliding rail 214 is parallel to the height direction Z of the hooking assembly 230. In this way, the success rate and stability of the hook 23 hooking the lifting lug 12a are improved, and the detection accuracy of the weight sensor 28 described later is improved. Of course, in some embodiments, the hook 23 can also be fixedly arranged on the rack 21. Specifically, the rack 21 further comprises a connecting plate 213 connected between the two side beams 211, and the sliding rail 214 is installed on the connecting plate 213.

[0081] Please refer again to Figure 4 and Figure 5In some embodiments, the hooking assembly 230 further comprises a beating member 27. The beating member 27 comprises a second driving member 271 and a beating rod 272, the second driving member 271 is installed on the rack 21 and is in driving connection with the beating rod 272. In this way, on the one hand, the beating member 27 can be used to beat the ton bag 1a, thereby improving the flowability of the material in the ton bag 1a when the material falls, reducing the residual amount, and thereby improving the unloading efficiency and unloading effect; on the other hand, the beating member 27 is integrated on the rack 21, which improves the integration degree and reduces the occupied space of the overall structure of the hooking assembly 230 to the cabinet 1, facilitating installation.

[0082] Specifically, the rack 21 further comprises a support plate 217 connected between the bottoms of the two side beams 211. The second driving member 271 is installed on the support plate 217 near one side of the limiting member 24, and is arranged to avoid the limiting member 24. The beating rod 272 is arranged on the side of the support plate 217 away from the limiting member 24. In this way, on the one hand, the support plate 217 arranges the beating rod 272 away from the limiting member 24, thereby avoiding movement interference between the beating rod 272 and the limiting member 24, improving the reliability and safety of the work of the hooking assembly 230; on the other hand, the beating member 27 is integrated on the hooking assembly 230, thereby reducing the occupied space of the beating member 27, making the structure of the automatic unpacking device 100 compact, reducing the assembly difficulty, and improving the production efficiency.

[0083] In the present embodiment, the protective cover 216 covers the outside of the support plate 217 and the two side beams 211. The limiting member 24 and the first driving member 25 are both installed on the two side beams 211 of the rack 21 through the support plate 217. Specifically, the support plate 217 can be integrated with the beating member 27, the limiting member 24 and the first driving member 25 as a whole structure, thereby optimizing the layout of the connection cable of the first driving member 25 and the second driving member 271, and reducing the problem of cable entanglement. Of course, in some other embodiments, at least one of the limiting member 24 and the first driving member 25 can also be directly installed on the side beam 211, and the installation position and installation manner of the limiting member 24 and the first driving member 25 are not limited in the present embodiment.
