[0048] Please also read Figure 8 , Fig. 9 as well as Fig.10 , Fig. 9 yes Figure 8 A schematic diagram of the structure of the middle limiter 132, Fig.10 1 is a schematic diagram of the structure of the hook structure 13 provided in an embodiment of the present application. The hook structure 13 includes a hook member 131 and a limit member 132. The hook member 131 is rotatably connected to the output shaft 121. The limit member 132 is fixedly connected to the output shaft 121. The limit member 132 is used to drive the hook member 131 to rotate with the output shaft 121. The hook member 131 is telescopically arranged relative to the housing 11.

[0049] The limiting member 132 includes a connecting portion 1321 and a limiting portion 1322. The connecting portion 1321 is fixedly connected to the output shaft 121. The connecting portion 1321 and the output shaft 121 can be fixedly connected together by welding, clamping, keyway connection, screw connection, bonding, etc. The limiting portion 1322 is connected to the side of the connecting portion 1321 away from the output shaft 121. The limiting portion 1322 is used to drive the hook member 131 to rotate. A limiting groove 1323 is provided on the limiting portion 1322. The hook member 131 is arranged in the limiting groove 1323. The limiting groove 1323 can be U-shaped, ㄩ-shaped, etc.

[0050] In some embodiments, the hook structure 13 further includes an elastic member 133. The elastic member 133 is disposed between the side wall of the limiting groove 1323 located in the circumferential direction of the output shaft 121 and the hook member 131. The limiting groove 1323 has a first side wall 1324 and a second side wall 1325 that are disposed opposite to each other along the circumferential direction of the output shaft 121. The first side wall 1324 may be located on a side of the limiting groove 1323 that is close to the front along the extension direction of the hook structure 13 relative to the housing 11, that is, on a side of the limiting groove 1323 that is close to the outlet 1131. The second side wall 1325 is located on a side of the first side wall 1324 that is away from the outlet 1131. The elastic member 133 is disposed between the first side wall 1324 and the hook member 131, and / or, the elastic member 133 is disposed between the second side wall 1325 and the hook member 131. A first mounting hole 1310 is formed on the hook member 131, and a second mounting hole 1326 is formed on the first side wall 1324 and / or the second side wall 1325. One of the two opposite ends of the elastic member 133 is accommodated in the first mounting hole 1310, and the other end is accommodated in the second mounting hole 1326, so as to limit the elastic member 133. When the hook member 131 extends out of the housing 11, the hook member 131 is subjected to an external force to compress the elastic member 133, and rotates relative to the output shaft 121. When the hook member 131 rotates to abut against the first side wall 1324 or the second side wall 1325, the elastic member 133 can play a buffering role, reduce the impact between the hook member 131 and the limiting member 132, thereby improving the structural stability and service life of the hooking and unhooking device 100. The elastic member 133 can be configured as a coil spring, a torsion spring, an elastomer, etc.

[0051] Please also read Figure 2 , Figure 3 , Figure 4 , Fig.11 as well as Fig.12 , Fig.11 is a schematic diagram of the structure of the hook member 131 provided in the embodiment of the present application when it is in a retracted state. Fig.121 is a schematic diagram of the structure of the hook member 131 provided in the embodiment of the present application when it is in an extended state. The hook member 131 has an extended state and a retracted state. When the hook member 131 is in the extended state, the hook member 131 is used to hook the sling 23 or hang the material bag 20. When the hook member 131 is in the retracted state, the hook member 131 is used to detach from the sling 23 or the material bag 20.

[0052] The hook member 131 includes a connecting rod 1311 and a hook rod 1312. One end of the connecting rod 1311 is rotatably connected to the output shaft 121, and the other end of the connecting rod 1311 is connected to the hook rod 1312. Exemplarily, the connecting rod 1311 can be rotatably connected to the output shaft 121 through a bearing to reduce friction resistance. The connecting rod 1311 is fixed relative to the output shaft 121 along the axial direction of the output shaft 121 to avoid falling off the output shaft 121. The limiting member 132 is used to limit the connecting rod 1311 and the limiting member 132 to rotate with the output shaft 121. The hook rod 1312 is bent relative to the connecting rod 1311 in the direction toward the output shaft 121, and is telescopic relative to the housing 11.

[0053] The hook rod 1312 may be in an arc shape. When the connecting rod 1311 drives the hook rod 1312 to rotate around the output shaft 121, so that the hook rod 1312 is extended relative to the housing 11, the movement track of the hook rod 1312 is circular. In this way, the opening size of the outlet 1131 can be made to correspond to the cross-sectional area of ​​the hook rod 1312, so as to avoid interference between the housing 11 and the hook rod 1312, thereby reducing the opening size of the outlet 1131, and reducing or avoiding external dust from entering the housing 11 through the outlet 1131. In addition, when the hook rod 1312 is retracted relative to the housing 11, the arc shape of the hook rod 1312 can also facilitate the sling 23 or the material bag 20 to fall off from the hook rod 1312, and reducing the opening size of the outlet 1131 can avoid the sling 23 or the material bag 20 from being stuck at the outlet 1131, thereby effectively improving the success rate of unhooking.

[0054] In some embodiments, the hook structure 13 can also be fixedly connected to the output shaft 121. Among them, the hook structure 13 can include a hook member 131, but does not include a stop member 132. The connecting rod 1311 is fixedly connected to the output shaft 121. The hook rod 1312 is connected to one end of the connecting rod 1311 away from the output shaft 121. The output shaft 121 is used to drive the connecting rod 1311 to rotate, and the connecting rod 1311 is used to drive the hook rod 1312 to extend or retract relative to the housing 11. In this way, the structure of the hooking and unhooking device 100 can be simplified, making the structure of the hooking and unhooking device 100 more compact.

[0055] The hooking and unhooking device 100 may further include a detection member 14. The detection member 14 is used to detect the position of the hook member 131. The detection member 14 is mounted on the housing 11. The detection member 14 may be provided as one or more. Exemplarily, the detection member 14 may be mounted on the housing 112. In some embodiments, the detection member 14 may also be mounted on the cover plate 111. In some embodiments, the detection member 14 may be provided as a plurality of detection members, and the plurality of detection members 14 jointly detect the position of the hook member 131, and the plurality of detection members 14 serve as backup for each other, so that after some of the detection members 14 are damaged, the remaining detection members 14 can still detect the position of the hook member 131, thereby improving the working stability of the hooking and unhooking device 100. All of the plurality of detection members 14 are mounted on the cover plate 111, or all of the plurality of detection members 14 are mounted on the housing 112, or some of the plurality of detection members 14 are mounted on the cover plate 111, and the other portion of the detection members 14 are mounted on the housing 112. In some embodiments, the hooking and unhooking system also includes an alarm device or a signal prompt device. When the detection member 14 detects the position of the hook member 131, the detection member 14 can trigger the alarm device to sound an alarm or trigger the signal prompt device to give a signal prompt to facilitate the technicians to perform operations.

[0056] Among them, the detection member 14 can be configured as a position sensor, and when the connecting rod 1311 of the hook member 131 moves to be opposite to the detection member 14, the connecting rod 1311 triggers the detection member 14. The position sensor can be an inductive position sensor, a photoelectric position sensor, a Hall element, a contact switch, etc. In some embodiments, the detection member 14 can also be configured as an angle sensor, and when the rotation angle of the connecting rod 1311 reaches a preset condition, the detection member 14 is triggered. The detection member 14 can also be configured as other types of sensors according to actual needs, which are not specifically limited in this application.

[0057] Exemplarily, the elastic member 133 can be arranged between the first side wall 1324 and the hook member 131, and the second mounting hole 1326 is provided on the first side wall 1324. When the hooking and unhooking device 100 performs unpacking operation, the driver 12 drives the output shaft 121 to rotate in the forward direction, and the output shaft 121 drives the hook member 131 to extend out of the housing 11 through the limiter 132, so that the hook member 131 is in an extended state. After the hook member 131 hooks the sling 23, when the material bag 20 and the hooking and unhooking device 100 are separated, the sling 23 pulls the hook member 131 to rotate around the output shaft 121, and the hook member 131 compresses the elastic member 133 until it abuts against the first side wall 1324 of the limiter 132. At this time, the position of the hook member 131 corresponds to the position of the detection member 14, and the hook member 131 triggers the detection member 14. The hooking and unhooking device 100 can determine that the hook member 131 hooks the sling 23 according to the detection signal sent by the detection member 14. When the hook member 131 is hooking the sling 23, the output shaft 121 is fixed and does not rotate. At this time, the rotation angle of the hook member 131 is limited by the width of the limit slot 1323. After the hook member 131 hooks the sling 23, the hook-and-unhook device 100 moves away from the material bag 20, so that the cover cloth 22 is torn off from the bag body 21 through the sling 23. After the cover cloth 22 is torn off, the elastic member 133 rebounds, so that the hook member 131 is reset, and the driver 12 drives the output shaft 121 to rotate in the opposite direction. The output shaft 121 drives the hook member 131 to retract into the housing 11 through the limit member 132, so that the sling 23 falls off the hook member 131. In some embodiments, after the hook-and-unhook device 100 completes the unpacking operation, the driver 12 can be controlled to drive the hook member 131 to be in an extended state, so as to perform the next unpacking operation or other operations again.

[0058] In some embodiments, when the hook member 131 is in the extended state and the hook rod 1312 extends out of the housing 11, the line between the end of the hook rod 1312 away from the connecting rod 1311 and the output shaft 121 is perpendicular to the horizontal plane. In this way, since the sling 23 will sag under the action of gravity, when the line between the end of the hook rod 1312 and the output shaft 121 is perpendicular to the horizontal plane, the hooking range of the hook rod 1312 in the direction perpendicular to the horizontal plane can be increased, thereby improving the success rate of the hook rod 1312 hanging the sling 23.

[0059] Please also read Figure 1 ,Figure,5, Figure 6 , Figure 7 and Fig.13 , Fig.131 is a schematic diagram of the structure of the hook structure 13 provided in some embodiments of the present application. In some embodiments, the elastic member 133 can also be arranged between the second side wall 1325 and the hook member 131. When the hooking and unhooking device 100 performs a hanging operation, the driver 12 drives the output shaft 121 to rotate in the forward direction, and the output shaft 121 drives the hook member 131 to extend out of the housing 11 through the limit member 132, so that the hook member 131 is in an extended state. When the material bag 20 and the hook-taking and unhooking device 100 are close to each other, so that the end of the hook member 131 abuts against the material bag 20, the hook member 131 is subjected to the resistance of the material bag 20 and rotates around the output shaft 121, and the hook member 131 compresses the elastic member 133 until it abuts against the second side wall 1325 of the limiting member 132. At this time, the position of the hook member 131 corresponds to the position of the detection member 14, and the hook member 131 triggers the detection member 14. The hook-taking and unhooking device 100 can determine that the hook member 131 abuts against the material bag 20 according to the detection signal sent by the detection member 14. When the hook-taking and unhooking device 100 and the material bag 20 continue to move closer, the hook member 131 can be inserted into the material bag 20. Among them, when the hook member 131 abuts against the material bag 20, the output shaft 121 is fixed and does not rotate, so as to prevent the hook member 131 from being squeezed and retracted into the housing 11. After the hook member 131 penetrates the material bag 20 , the hook-hanging and unhooking device 100 can hang the material bag 20 , and transport or unpack the material bag 20 .

[0060] Among them, in some embodiments, after the hook member 131 penetrates the material bag 20, the hanging and unhooking device 100 can also move a short distance in the direction away from 20, so that the hook member 131 extends a short distance relative to the shell. The distance can reset the elastic member 133 and prevent the hook member 131 from detaching from the material bag 20. At this time, the position of the hook member 131 is spaced apart from the detection member 14. When the hanging and unhooking device 100 receives a change in the detection signal generated by the detection member 14, it determines that the hook member 131 has penetrated into the material bag 20. Subsequently, the hanging and unhooking device 100 can move in the direction close to the material bag 20, so that the penetration depth of the hook member 131 into the material bag 20 meets the requirements.

[0061] like Figure 6As shown, after the hook member 131 penetrates into the material bag 20, the material bag 20 can be unloaded to improve the degree of automation. When the hook member 131 penetrates into the material bag 20, it can penetrate from the side of the material bag 20. When the material in the material bag 20 is unloaded, the bag shape of the material bag 20 will be deformed, and the traditional clamping device for clamping the material bag 20 cannot maintain stability, causing the material bag 20 to fall off. The hanging and unhooking device 100 in the embodiment of the present application penetrates into the material bag 20 through the hook member 131, and the material bag 20 can still be stably hung after the material bag 20 is deformed, which effectively avoids the problem of the material bag 20 falling off, improves the material emptying rate in the material bag 20, improves the degree of automation of the hanging of the material bag 20, and improves the unloading efficiency. Figure 7 As shown, after the material bag 20 is unloaded, the driver 12 drives the output shaft 121 to rotate in the opposite direction, and the output shaft 121 drives the hook member 131 to retract into the housing 11 through the limiter 132, so that the material bag 20 falls off the hook member 131. In some embodiments, after the material bag 20 is unloaded, the hanging and unhooking device 100 can also hang the empty material bag 20 to the recycling area and then unhook the material bag 20, thereby reducing the manual work of recycling the material bag 20. Among them, the end of the hook rod 1312 away from the connecting rod 1311 can be provided with a spike structure to facilitate piercing the material bag. For example, the end of the hook rod 1312 away from the connecting rod 1311 is configured as a pointed cone.

[0062] In some embodiments, the elastic member 133 may be provided in plurality, for example, the elastic member 133 may be provided in two, one of the two elastic members 133 is provided between the first side wall 1324 and the hook member 131, and the other is provided between the second side wall 1325 and the hook member 131. Among them, the detection member 14 may be provided in two. When the hook member 131 is in the extended state, one of the two detection members 14 is located on the side of the connecting rod 1311 close to the outlet 1131, and the other detection member 14 is located on the side of the connecting rod 1311 away from the outlet 1131. When the hook member 131 is in the extended state, the hook member 131 extends out of the shell 11, and when the end of the hook member 131 abuts against the material bag 20, the material bag 20 and the hanging and unhooking device 100 are close to each other, and the hook member 131 is subjected to the resistance of the material bag 20 and rotates around the output shaft 121, and the hook member 131 compresses the elastic member 133 close to the second side wall 1325 until it abuts against the second side wall 1325. At this time, the position of the hook member 131 corresponds to the position of the detection member 14 away from the side of the outlet 1131, and the hook member 131 triggers the detection member 14. The hanging and unhooking device 100 determines that the hook member 131 abuts against the material bag 20 according to the detection signal sent by the detection member 14. When the hanging and unhooking device 100 and the material bag 20 continue to move closer, the hook member 131 can be inserted into the material bag 20. After the hooking and unhooking device 100 makes the hooking member 131 penetrate into the material bag 20, the hooking and unhooking device 100 moves a short distance in the direction away from the material bag 20, so that the hooking member 131 extends a short distance relative to the housing, so that the hooking member 131 compresses the elastic member 133 close to the first side wall 1324 until it abuts against the first side wall 1324. At this time, the position of the hooking member 131 corresponds to the position of the detection member 14 away from the outlet 1131. The hooking member 131 triggers the detection member 14, and the hooking and unhooking device 100 determines that the hooking member 131 has penetrated into the material bag 20 according to the detection signal sent by the detection member 14. Then, the hooking and unhooking device 100 can move in the direction close to the material bag 20, so that the penetration depth of the hooking member 131 into the material bag 20 meets the requirements. In this way, through the joint detection of the two detection members 14, the accuracy of the hooking and unhooking device 100 during operation can be improved.

[0063] In some embodiments, the hooking and unhooking device 100 may further include a stopper, which is fixed in the shell 112. When the hook structure 13 is in an extended state and / or when the hook structure 13 is in a retracted state, the stopper stops the hook structure 13 to limit the movement range of the hook structure 13 in the shell 112.

[0064] See also Fig.14 , Fig.141 is a schematic diagram of the structure of the hook member 131 provided in some embodiments of the present application. In some embodiments, a plurality of hook rods 1312 are provided, and the plurality of hook rods 1312 are arranged at intervals along the axial direction of the output shaft 121. A connecting rod 1311 is provided, and the plurality of hook rods 1312 are connected side by side to the end of the connecting rod 1311 away from the output shaft 121. The plurality of hook rods 1312 can, on the one hand, improve the success rate of the hook rod 1312 in hooking the sling 23 and improve the production efficiency, and on the other hand, can improve the overall structural strength of the hook member 131 and prevent the hook member 131 from bending or breaking.

[0065] See also Fig.15 , Fig.15 1 is a schematic diagram of the structure of the hooking and unhooking device 100 after removing some structures in some embodiments of the present application. In some embodiments, a plurality of hook structures 13 are provided, and the plurality of hook structures 13 are arranged side by side on the output shaft 121. Each hook structure 13 includes a hook member 131 and a stop member 132. The plurality of hook structures 13 can improve the success rate of the hook rod 1312 hooking the sling 23, and improve the overall structural strength of the hook structure 13, which is conducive to the hoisting and transportation of the material bag 20.

[0066] In some embodiments, the driver 12 includes a plurality of output shafts 121, and the hook structures 13 are provided in a plurality, and at least one hook structure 13 is provided on each output shaft 121. Exemplarily, the driver 12 is configured as a dual-axis driver, and the two output shafts 121 extend along opposite sides of the driver 12, and a hook structure 13 is provided on each output shaft 121. In some embodiments, the output shafts 121 can also be provided in three, four, etc. The hook structures 13 on each output shaft 121 can also be provided in two, three, etc. In some embodiments, the driver 12 can be provided in a plurality, and at least one hook structure 13 is provided on the output shaft 121 of each driver 12.

[0067] Please also read Figure 1 , Figure 8 and Fig.11, the side wall of the shell 112 corresponding to the hook rod 1312 is in an arc shape to match the shape of the hook rod 1312, reduce the structural size of the shell 11, and make the hooking and unhooking device 100 compact. In some embodiments, the shell 11 also includes a baffle 113 connected to the shell 112. The baffle 113 is located at the end of the shell 112 along the extension direction of the hook structure 13. The cover plate 111, the shell 112 and the baffle 113 enclose a receiving chamber 110. The baffle 113 is protruded relative to the shell 112 in a direction perpendicular to the extension direction of the hook structure 13, that is, the baffle 113 protrudes relative to the shell 112 and the cover plate 111 along the axial direction of the output shaft 121. In this way, the baffle 113 can play a role of shielding and protection, reduce the escape of dust to the driver 12 installed on the shell 112 or the cover plate 111, and reduce the deposition of dust on the shell 112. In some embodiments, along the axial direction of the output shaft 121, the edge of the baffle 113 can also be flush with the housing 112 and the cover plate 111 respectively. An outlet 1131 is provided on the baffle 113. The baffle 113 and the housing 112 can be fixedly connected together by bonding, clamping, melting, welding, etc., or the baffle 113 can be integrally formed with the housing 112.

[0068] The housing 11 is also provided with an air inlet 1121 and a powder outlet 1132, both of which are connected to the receiving chamber 110. The air inlet 1121 is provided on the housing 112. The air inlet 1121 is located on the housing 112 at a position away from the baffle 113. The powder outlet 1132 is used to discharge the dust entering the receiving chamber 110 to prevent the dust from damaging the hook structure 13, the driver 12, the detection member 14, etc. The powder outlet 1132 is provided on the baffle 113. The powder outlet 1132 is located at the position where the baffle 113 and the arc-shaped side wall of the housing 112 meet, so as to avoid forming a dead angle at the position where the baffle 113 and the housing 112 meet, so that all the dust in the receiving chamber 110 can be discharged outside the receiving chamber 110. When the hook-and-unhook device 100 is installed on the supporting equipment, the arc-shaped side wall of the shell 112 is located on the side of the shell 112 close to the ground, and the powder outlet 1132 is located near the end of the baffle 113 close to the ground. The air inlet 1121 and the outlet 1131 are both located on the side of the powder outlet 1132 away from the ground.

[0069] The hanging and unhooking device 100 further includes an air pipe connector 15 disposed at the air inlet 1121. The air pipe connector 15 is used to connect to an external air source. When the hanging and unhooking device 100 is operating, the external air source can spray gas into the receiving chamber 110 to maintain a positive pressure state in the receiving chamber 110, thereby reducing or preventing external dust from entering the receiving chamber 110 from the outlet 1131. After dust enters the receiving chamber 110, the dust can also be discharged from the powder outlet 1132 by the injected gas, thereby ensuring the cleanliness of the inside of the receiving chamber 110. In addition, the gas discharged from the powder outlet can also form an airflow stop zone on the side of the hanging and unhooking device 100 close to the material bag 20 through the airflow, effectively preventing dust from contacting the hanging and unhooking device 100 or entering the receiving chamber 110 from the outlet 1131. In some embodiments, the powder outlet 1132 can also be arranged on the housing 112, for example, opened on the side of the housing 112 close to the ground.
