Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0060] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings).

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0062] In this application, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0063] In addition, the technical solutions between the various embodiments of the present application can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0064] The present application provides a packaging device, which includes a gripping device 30, a bag opening device 20 and a blanking device 10. The bag opening device 20 and the blanking device 10 are arranged above the gripping device 30 with an interval, and one end of the gripping device 30 is docked with the bag opening device 20, and the other end extends to one side of the blanking device 10 until it is docked with a downstream workstation; wherein, the bag opening device 20 is used to grip ton bags and open the ton bags from a first state to a second state, and the bag opening device 20 is also used to move the ton bags opened to the second state onto the gripping device 30; the gripping device 30 is used to grip the ton bags and transfer the ton bags from the bag opening device 20 to the blanking device 10; the blanking device 10 is used to seal the bag mouth of the ton bag and fill materials into the ton bag, and the gripping device 30 is also used to transfer the ton bags to the downstream workstation after the blanking device 10 is filled.

[0065] 1 , the packaging device further comprises a frame 50 , and the gripping device 30 , the bag opening device 20 , and the unloading device 10 are all installed in the frame 50 to improve the integration of the packaging device.

[0066] A door is located on one side of the frame 50. When opened, it is used to load the ton bags in a first state into the packaging equipment. The first state refers to the ton bags being neatly folded. A conveyor belt, such as a belt module or roller conveyor, is located at the bottom of the other side of the frame 50. This conveyor belt connects to other equipment at downstream stations. Once the ton bags are filled, the gripping device 30 transfers the material to the conveyor belt, from which it is transported to other equipment at downstream stations.

[0067] Referring to Figure 2, after a ton bag in the first state is loaded into the packaging equipment, the bag opening device 20 first grasps the ton bag in the first state and opens the ton bag to the second state. The second state refers to the state of the ton bag after it is opened, with the bag opening facing in the right direction, so that the material can be easily filled into the ton bag through the bag opening at the top.

[0068] During the process of the bag opening device 20 opening the ton bag to the second state, the gripping device 30 moves to the bottom of the bag opening device 20 and stands by. After the ton bag is opened to the second state, the edge of the ton bag has a protruding edge for the gripping device 30 to clamp.

[0069] The grabbing device 30 grabs the ton bag and drives the ton bag to move to the bottom of the unloading device 10. The unloading device 10 extends into the ton bag and fills the ton bag with material.

[0070] It can be understood that when the blanking device 10 is extended into the bag opening of the ton bag, there is a gap between the bag opening and the edge of the blanking device 10. Therefore, during the process of filling the material, the blanking device 10 seals the edge gap of the bag opening to prevent the material from flying out through the gap and causing dust.

[0071] In addition, during the process of filling materials, the gripping device 30 keeps the ton bag clamped. After filling with foreign currency, the gripping device 30 directly transports the ton bag to the downstream workstation, reducing unnecessary operations and preventing the ton bag from shifting in position during the unloading process.

[0072] The technical solution of this application utilizes an integrated assembly approach. After opening a bag, the bag opening device 20 directly docks with the gripping device 30 at the bottom. The gripping device 30 then transfers the ton bag to the unloading device 10 for filling. Once filling is complete, the gripping device 30 transfers the ton bag to the next processing station. The gripping device 30, bag opening device 20, and unloading device 10 are compact, reducing space requirements. The integrated approach eliminates assembly and commissioning steps, further reducing equipment operating costs.

[0073] Please refer to Figure 3, the blanking device 10 includes a first lifting mechanism 11, a connecting plate 12 and a sealed blanking assembly 13. The first lifting mechanism 11 is arranged above the grasping device 30; the connecting plate 12 is arranged on the first lifting mechanism 11; the sealed blanking assembly 13 is arranged on the connecting plate 12, and the sealed blanking assembly 13 is used to seal the bag opening of the ton bag and fill the ton bag with material.

[0074] The first lifting mechanism 11 can be installed on the top of the frame 50. The first lifting mechanism 11 can be a linear module, a lifting cylinder, or other mechanisms.

[0075] The connecting plate 12 is bolted to the lifting base of the first lifting mechanism 11 as a supporting structure to improve its stability. When the lifting base of the first lifting mechanism 11 moves up and down, it can drive the connecting plate 12 and the components mounted on the connecting plate 12 to move up and down synchronously.

[0076] The sealed blanking assembly 13 is mounted on the connecting plate 12 and includes a blanking portion, within which is a receiving cavity. This cavity has interconnecting holes at the top and bottom. The top is connected to an external feeding device, and the bottom is designed to extend into the opening of a ton bag. When the feeding device introduces material into the receiving cavity, the material, under the action of gravity, passes through the cavity and falls through the hole at the bottom into the ton bag.

[0077] After the blanking portion extends into the bag opening, a gap is formed between the edge of the bag opening and the blanking portion. The sealing blanking assembly 13 also has a clamping portion. When the blanking portion on the sealing blanking assembly 13 extends into the bag opening, the clamping portion clamps the bag opening onto the blanking portion, thereby sealing the gap.

[0078] The blanking portion is formed by a blanking barrel 131. In this embodiment, the blanking barrel 131 is cylindrical, but other shapes can also be used. The top and bottom of the blanking barrel 131 are connected to form a receiving cavity, which is also a smooth cylindrical cavity to guide the material from top to bottom.

[0079] One end of the connecting plate 12 is connected and fixed to the first lifting mechanism 11, and the other end is provided with a mounting hole, into which the discharge barrel 131 is inserted, and the edge is fixed to the connecting plate 12 by bolts or welding. The top can be connected to the feeding equipment through a pipeline to realize material transmission.

[0080] The length of the connecting plate 12 is adjusted so that the position of the discharge barrel 131 is located just above the grabbing device 30. When the first lifting mechanism 11 descends, it can drive the discharge barrel 131 to just extend into the bag opening.

[0081] When the material is filled, the first lifting mechanism 11 rises and the discharge barrel 131 extends from the bag opening of the ton bag, thereby avoiding interference when the grabbing device 30 transfers the ton bag to the downstream station.

[0082] The clamping portion is formed by a clamping arm 132. The clamping arm 132 can be installed on one side of the discharge barrel 131, wherein the clamping arm 132 can be installed on the connecting plate 12 or directly installed on the frame 50.

[0083] As an embodiment, when the clamping arm 132 is installed on the connecting plate 12, the clamping arm 132 includes a mounting plate 1321, a bracket 1322, an abutment plate 1323 and a driving member 1324, and the mounting plate 1321 is arranged on the connecting plate 12; one end of the bracket 1322 is hinged to the mounting plate 1321; the abutment plate 1323 is arranged on the other end of the bracket 1322, and the edge shape of the abutment plate 1323 is adapted to the outer wall shape of the discharge barrel 131; the driving member 1324 is connected to the bracket 1322, and the driving member 1324 is used to drive the bracket 1322 to rotate, and the bracket 1322 rotates to drive the abutment plate 1323 to approach or move away from the discharge barrel 131.

[0084] The mounting plate 1321 is L-shaped, with one side being fixed to the connecting plate 12 via bolts, and the other side being hinged to the bracket 1322. The other end of the bracket 1322 is connected to the abutment plate 1323. The driving member 1324 can be a pneumatic cylinder, with the piston rod of the cylinder connected to the bracket 1322. When the piston rod is extended or retracted, it drives the bracket 1322 to rotate about the hinged connection with the mounting plate 1321.

[0085] When the bracket 1322 rotates, it drives the abutment plate 1323 to rotate synchronously. Please refer to Figure 3. The bracket 1322 is set on the left side of the discharge barrel 131. When the bracket 1322 rotates clockwise, it drives the abutment plate 1323 away from the discharge barrel 131; when the bracket 1322 rotates counterclockwise, it drives the abutment plate 1323 close to the discharge barrel 131 until it abuts against the discharge barrel 131, thereby clamping the bag mouth of the ton bag on the outer wall of the discharge barrel 131.

[0086] To improve the stability of the abutment plate 1323 in clamping the bag opening, the abutment plate 1323 has a certain length to increase the length or area of ​​contact with the ton bag. Similarly, the bracket 1322 has a certain width, so two mounting plates 1321 can be installed on the connecting plate 12. The two sides of the bracket 1322 are respectively hinged to the two mounting plates 1321 to improve the stability of the bracket 1322's rotation.

[0087] As another embodiment, the number of the clamping arms 132 can be multiple. In this embodiment, two clamping arms 132 are provided as an example. The two clamping arms 132 are provided on the connecting plate 12 opposite to each other.

[0088] The lower barrel 131 is cylindrical, with one abutment plate 1323 and the other abutment plate 1323 also being semicircular. When the two abutment plates 1323 abut the outer wall of the lower barrel 131, they form a ring with a diameter that matches the outer diameter of the lower barrel 131. This ring wraps around the entire opening of the ton bag and abuts against it.

[0089] It can be understood that when the number of the clamping arms 132 is greater than two, such as three or four, the multiple clamping arms 132 can form corresponding ring shapes when they abut against the outer wall of the discharge barrel 131.

[0090] In addition, in addition to forming a ring shape, when the discharge barrel 131 is in the shape of a quadrangular prism or other special shapes, it can be enclosed to form a corresponding shape.

[0091] As another embodiment, the mounting plate 1321 can be directly mounted on the frame 50, and the bracket 1322 is mounted on the mounting plate 1321. The driving member 1324 is a linear module, and the abutment plate 1323 is mounted on a movable base of the linear module. The linear module moves toward or away from the discharge barrel 131. Therefore, when the movable base of the linear module moves, it drives the abutment plate 1323 to move toward or away from the discharge barrel 131.

[0092] The bracket 1322 has a bending structure at a position corresponding to the connecting plate 12 to avoid interference with the connecting plate 12 during rotation.

[0093] In one embodiment, the clamping arm 132 further includes a flexible sealing strip 1325, which is disposed on the abutment plate 1323. The flexible sealing strip 1325 can be made of materials such as rubber or sponge. When the abutment plate 1323 abuts the discharge barrel 131, the flexible sealing strip 1325 deforms to better conform to the outer wall of the discharge barrel 131.

[0094] In one embodiment, please refer to Figures 4~5, the bag opening device 20 includes a first conveying mechanism 21, a first adsorption component 24, a second adsorption component, a second lifting mechanism 22 and a third lifting mechanism 23. The first conveying mechanism 21 is arranged above the grasping device 30; the second lifting mechanism 22 and the third lifting mechanism 23 are arranged on the first conveying mechanism 21 relative to each other; the first adsorption component 24 is rotatably arranged on the second lifting mechanism 22; the second adsorption component is arranged on the third lifting mechanism 23.

[0095] As an embodiment, the first conveying mechanism 21 can be a bidirectional module, or can be achieved by splicing two linear modules and setting them in opposite directions to achieve bidirectional drive. The bidirectional module drive method is adopted, and two movable slides are provided on the bidirectional module to ensure the synchronization of the second lifting mechanism 22 and the third lifting mechanism 23 during the movement process.

[0096] Referring to Figure 6 , the first adsorption assembly 24 and the second adsorption assembly are positioned opposite each other. The first adsorption assembly 24 is additionally equipped with a power unit 312 to drive the rotation of the first adsorption assembly 24. It will be appreciated that in actual use, new ton bags are typically folded and stacked together, that is, in the first state, for easy storage. Therefore, when the first adsorption assembly 24 removes a bag, the bag is in a horizontal position.

[0097] Through debugging, the initial position of the first adsorption component 24 is set to be just above the position where the ton bag is placed, so that the first adsorption component 24 is convenient for taking the bag.

[0098] When removing a bag, the first suction assembly 24 descends to a certain height, then contacts the ton bag in the first position and absorbs the bag, completing the bag removal process. It should be noted that some ton bags have a different opening shape than the bag body, such as a cylindrical opening and a cubic body. Therefore, adjustments can be made to ensure that the first suction assembly 24, after descending, fits snugly against the ton bag's opening, thereby absorbing one side of the bag opening.

[0099] After removing the bag, the first suction assembly 24 rotates so that the ton bag faces the side of the second suction assembly. Typically, the ton bag is placed directly below the first suction assembly 24. Therefore, when removing the bag, the suction direction of the first suction assembly 24 faces downward. Since the first and second suction assemblies are positioned relative to each other, the first suction assembly 24 can be driven to rotate 90 degrees toward the side of the second suction assembly, driving the ton bag to a vertical position with the bag opening facing upward, facilitating filling of the ton bag. The side of the ton bag facing away from the first suction assembly 24 faces the second suction assembly.

[0100] After the rotation, the first conveying mechanism 21 drives the second adsorption assembly and the first adsorption assembly 24 to move toward each other synchronously. Finally, the first adsorption assembly 24 and the second adsorption assembly clamp the ton bag and adsorb both sides of the ton bag.

[0101] After clamping, the first conveying mechanism 21 is controlled to drive the first adsorption assembly 24 and the second adsorption assembly to move in opposite directions, and the bag opening of the ton bag is stretched open by pulling the ton bag toward both sides.

[0102] The first adsorption component 24 includes a rotating part 241, an adsorption part 242, a positioning part 243 and a controller. The rotating part 241 is arranged on the second lifting mechanism 22; the adsorption part 242 is arranged on the rotating part 241; the positioning part 243 is arranged on the adsorption part 242, and the positioning part 243 is used to collect the position information of the ton bag; the controller is used to adjust the stroke of the first conveying mechanism 21 according to the position information.

[0103] The adsorption member 242 can be a buffering suction cup with a buffering function, or a vacuum sponge suction cup, etc. It can be replaced according to the use environment. The adsorption member 242 and the rotating member 241 can be connected by a snap-fit ​​method, so as to facilitate subsequent replacement and maintenance.

[0104] The positioning member 243 is also mounted on the adsorption member 242. The positioning member 243 can detect the position of the ton bag. The positioning member 243 can include a distance sensor and a color mark sensor, etc., so as to detect and calculate the position of the ton bag.

[0105] The positioning member 243 feeds back the position information of the ton bag to the controller, which then implements closed-loop control based on the feedback position information. By adjusting the stroke of the first conveying mechanism 21, the adsorption position of the first adsorption assembly 24 is adjusted, ensuring that the first adsorption member 242 is accurately attached to the opening of the ton bag, thereby improving accuracy.

[0106] The color code sensor can also clearly identify the position and direction of the bag opening of the ton bag, thereby further improving the accuracy of the first adsorption member 242 in grabbing.

[0107] 7-8 , the grabbing device 30 includes a second conveying mechanism 31, a grabbing assembly 32 and a detection member. The second conveying mechanism 31 is arranged at the bottom of the bag opening device 20 and the unloading device 10; the grabbing assembly 32 is movably arranged on the second conveying mechanism 31; the detection member is arranged on the grabbing assembly 32, and the grabbing assembly 32 is used to clamp the ton bag and drive the ton bag to move on the second conveying mechanism 31. The detection member is used to detect whether the grabbing assembly 32 clamps the ton bag in place.

[0108] The second conveying mechanism 31 can be a linear module or a track 311 and a power device 312. For example, the second conveying mechanism 31 specifically includes two tracks 311 arranged opposite to each other, each track 311 is equipped with two power devices 312, and each power device 312 is correspondingly equipped with one of the grabbing assemblies 32. The power device 312 can drive the two grabbing assemblies 32 to move toward each other, and can also drive the two grabbing assemblies 32 to move along the moving extension direction of the track 311.

[0109] By adjusting the installation position and installation direction of the grabbing components 32 , the two grabbing components 32 are made to face each other, so that when the grabbing components 32 are driven to move, the two grabbing components 32 are driven to move toward each other or away from each other.

[0110] When grabbing a ton bag, as shown in Figure 9, the grabbing assemblies 32 move to the corresponding position of the ton bag, with the ton bag positioned between the two grabbing assemblies 32. The two grabbing assemblies 32 move toward each other until they abut the left and right sides of the ton bag, thereby grabbing the ton bag. When releasing the ton bag, the two grabbing assemblies 32 move away from each other and detach from the ton bag.

[0111] During the process of grabbing and releasing the ton bag, the ton bag is detected by the detection element. When the grabbing assembly 32 performs the grabbing operation, the detection element detects the presence of the ton bag, indicating that the grabbing is in place. If the presence of the ton bag is not detected, it means that the grabbing is not successful, and the grabbing assembly 32 can be controlled to grab again. Alternatively, an external buzzer, indicator light, etc. can be connected to provide an alarm prompt, so that the on-site operator can take timely action.

[0112] The two grabbing assemblies 32 are arranged as a group on both sides of the second conveying mechanism 31, and cooperate with each other to clamp the left and right sides of the bulk bag.

[0113] According to needs, multiple groups of the grabbing components 32 can be set on the second conveying mechanism 31, and one group of the grabbing components 32 can be arranged to move back and forth between different workstations to achieve interaction between the multiple groups of the grabbing components 32, thereby improving the overall production rhythm and production efficiency.

[0114] It can be understood that when the number of the grabbing components 32 increases, the number of the second conveying mechanism 31 and the detection components should also increase accordingly to meet the grabbing and detection requirements of the grabbing components 32.

[0115] In one embodiment, the grabbing assembly 32 includes a shell 321, a fixed plate 322, a clamping drive 323 and a movable plate 324, the shell 321 is arranged on the second conveying mechanism 31; the fixed plate 322 is arranged on the shell 321; the clamping drive 323 is arranged in the shell 321; the movable plate 324 is connected to the clamping drive 323, and the clamping drive 323 is used to drive the movable plate 324 to move toward or away from the fixed plate 322; the detection component is arranged on the fixed plate 322 and / or the movable plate 324.

[0116] One end of the shell 321 is used to connect to the power device 312 on the second transmission mechanism 31, and the other end extends to the track 311 on the other side. The other end of the shell 321 is provided with the fixing plate 322, one end of the fixing plate 322 is connected to the shell 321, and the other end extends to the side away from the shell 321.

[0117] The movable plate 324 is disposed on the same side as and opposite to the fixed plate 322. The clamping drive member 323 is installed in the housing 321. Driven by the clamping drive member 323, the movable plate 324 can move toward or away from the fixed plate 322.

[0118] The movable plate 324 and the fixed plate 322 extend toward the other side rail 311 so as to contact the ton bag between the two rails 311 to achieve clamping.

[0119] Correspondingly, the edges of the ton bag have raised edges for the movable plate 324 to clamp with the fixed plate 322. A bag-stretching device is provided upstream of the ton bag grabbing and detecting device to ensure that the ton bag is already formed to a certain extent when it flows into the ton bag grabbing and detecting device, thereby facilitating the clamping of the edges by the fixed plate 322 and the movable plate 324.

[0120] During the clamping operation, the movable plate 324 moves toward the fixed plate 322, abuts against the edge of the ton bag, and continues to move until it abuts against the fixed plate 322, thereby clamping the ton bag. Conversely, during the loosening operation, the movable plate 324 moves away from the fixed plate 322, loosening the clamped edge of the ton bag.

[0121] In one embodiment, the packaging equipment further includes a loading mechanism 40 , which is movably disposed at the bottom of the bag opening device 20 , and has a placement platform for placing the ton bags.

[0122] The top of the feeding mechanism 40 has a flat surface to form the placement platform for placing the ton bags in the first i state.

[0123] The feeding mechanism 40 can be raised and lowered. It can be understood that multiple ton bags are stacked to a certain height. When a certain number of ton bags are used, the height drops. In order to ensure that the bag opening device 20 can stably grab the ton bags, when the height of the ton bags drops, the feeding mechanism 40 rises a certain distance, thereby ensuring that it can stably grab the ton bags.

[0124] The above description is merely an optional embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made using the contents of the present application specification and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
