Technical Field

[0001] This application relates to the technical field of packaging machinery, and in particular to a ton bag packaging machine. Background Technology

[0002] Currently, ton bags, also known as flexible container bags or space bags, are a type of medium-sized bulk container. They are typically made of polyester fiber materials such as polypropylene and polyethylene, and processed using woven fabrics or composite materials.

[0003] like Figure 1 As shown, lifting lugs 11 are provided at the four corners of the top of the ton bag 1 to facilitate lifting. The top of the ton bag 1 is also provided with a bag opening 12 to facilitate loading and unloading of goods.

[0004] The ton bag packaging machine in the prior art is a device used to package materials into ton bags. However, the ton bag packaging machine in the prior art often adopts semi-automatic equipment, which requires manual feeding, has low processing efficiency, and requires a lot of labor intensity for operators. Summary of the Invention

[0005] In order to reduce the labor intensity of operators, this application provides a ton bag packaging machine, which adopts the following technical solution: A ton bag packaging machine includes a frame, a hopper, a ton bag placement area, a ton bag feeding device, a bag opening support device, a material feeding device, and a conveyor line. The ton bag feeding device includes a robotic arm and a bag opening gripping mechanism. The bag opening support device includes a bag opening support base, a fixing mechanism, a pulling mechanism, and a spreading mechanism. The material feeding device includes a driving mechanism, which includes a material feeding base, a material feeding pipe installed on the material feeding base, a driving component installed on the frame for driving the material feeding base to move, and a fixing component for fixing the bag opening. An inflation pipe is connected to the material feeding pipe. The material feeding pipe is slidably connected to the outer wall of the material hopper discharge pipe. A hanging mechanism for lifting the lifting lugs is installed on the material feeding base. A feeding mechanism for sending ton bags filled with materials out of the conveyor line is installed on the frame.

[0006] First, the ton bag is placed in the ton bag placement area. Then, the bag mouth is clamped by the bag mouth clamping mechanism. Next, a robotic arm transports the ton bag to the bag mouth support base. Then, a fixing mechanism secures the bag mouth, followed by the bag mouth clamping mechanism releasing the bag mouth. Next, a pulling mechanism pulls the bag mouth open, followed by a supporting mechanism to open the bag mouth. Then, the supporting mechanism sends the ton bag to the feeding base. Next, a drive assembly drives the feeding base to move downwards, driving the feeding pipe to insert into the bag mouth. Then, a fixing assembly secures the bag mouth, followed by the supporting mechanism releasing the bag mouth. Then, air is inflated into the ton bag through the inflation pipe, followed by the lifting mechanism lifting the lifting lugs. Next, material is injected into the ton bag through the discharge pipe of the hopper. The conveyor line moves synchronously with the feeding mechanism. Finally, the feeding mechanism sends the ton bag filled with material off the conveyor line, thus completing the ton bag packaging process. In summary, by adopting the above technical solution, the labor intensity of operators can be reduced.

[0007] Optionally, the bag gripping mechanism includes multiple sets of first suction cup assemblies mounted on the robotic arm handle and two gripping cylinders hinged to the robotic arm handle; the piston rod of the gripping cylinder is hinged with a gripper; the multiple sets of first suction cup assemblies are used to adsorb the front of the bag opening, and the two grippers are used to press against the back of the bag opening.

[0008] By adopting the above technical solution, when it is necessary to grip the bag opening, the robotic arm first drives the bag opening gripping mechanism to the ton bag placement area, and then multiple sets of first suction cup components adsorb the front of the bag opening. Next, the piston rod of the gripping cylinder drives the gripper to rotate, thereby pressing against the back of the bag opening, thus gripping the bag opening. In summary, the bag opening gripping mechanism facilitates the gripping of the bag opening.

[0009] Optionally, the fixing mechanism includes a support plate mounted on the base of the bag opening, two first fixing cylinders hinged to the top of the support plate, and pressure plates respectively hinged to the piston rods of the two first fixing cylinders.

[0010] By adopting the above technical solution, the bag opening is first clamped by the bag opening clamping mechanism, and then the bag opening clamping mechanism is driven to the support plate by the robot arm. Next, the first fixing cylinder is activated. At this time, the piston rod of the first fixing cylinder drives the pressure plate to press the bag opening tightly. After the pressure plate presses the bag opening tightly, the bag opening is released by the bag opening clamping mechanism, and then the bag opening is opened by the opening pulling mechanism. In summary, the fixing mechanism is designed to facilitate the fixing of the bag opening.

[0011] Optionally, the opening mechanism includes two vertical plates mounted on the base of the bag opening, and an opening cylinder is mounted on one side of each vertical plate. The piston rod of the opening cylinder is equipped with a second suction cup assembly.

[0012] By adopting the above technical solution, after the pressure plate presses the bag opening, the opening cylinder is activated first. At this time, the piston rod of the opening cylinder drives the second suction cup assembly to move towards the bag opening. Then, the two sets of second suction cup assemblies adsorb the two sides of the bag opening. Subsequently, the piston rod of the opening cylinder drives the two sets of second suction cup assemblies to move in opposite directions, thereby opening the bag opening. In summary, the opening mechanism facilitates opening the bag opening.

[0013] Optionally, the opening mechanism includes a first drive motor mounted on the top of the bag opening base, a first lead screw mounted on the output shaft of the first drive motor, and a guide rod mounted on the top of the bag opening base; an opening seat is slidably connected to the top of the bag opening base, and opening sleeves are respectively installed on both sides of the opening seat, one opening sleeve is threaded to the first lead screw, and the other opening sleeve is slidably connected to the guide rod; an opening cylinder is hinged to the opening seat, and a flipping frame is hinged to the piston rod of the opening cylinder, with a top of the flipping frame mounted on... There are two expansion rods, and an expansion plate is installed at the end of each expansion rod away from the tilting frame. A limit cylinder is hinged to one side of the expansion plate, and the piston rod of the limit cylinder is hinged to a limit rod. A horizontal rail is installed on the top of the tilting frame, and a connecting seat is installed at the bottom of each of the two expansion rods. Both connecting seats are slidably connected to the horizontal rail. A second drive motor is installed on the top of the tilting frame, and a double-threaded screw is installed on the output shaft of the second drive motor. The two connecting seats are respectively threaded to the two ends of the double-threaded screw.

[0014] By adopting the above technical solution, the piston rod of the expanding cylinder first drives the tilting frame to rotate downwards. The downward rotation of the tilting frame drives the two expanding plates to rotate downwards, thus allowing the two expanding plates to rotate into the bag opening. Next, the second drive motor is started. At this time, the output shaft of the second drive motor drives the double threaded screw to rotate. The rotation of the double threaded screw drives the two connecting seats to move in opposite directions. The two connecting seats moving in opposite directions drive the two expanding plates to move in opposite directions, thus opening the bag opening. Then, the limiting cylinder is started. At this time, the piston rod of the limiting cylinder drives the limiting rod to rotate to limit the outer wall of the bag opening. Next, the first drive motor is started. At this time, the output shaft of the first drive motor drives the first screw to rotate. The rotation of the first screw drives the expanding seat to move. The movement of the expanding seat drives the ton bag to move, which facilitates the transportation of the ton bag to the unloading pipe. In summary, the opening mechanism is designed to facilitate the opening of the bag opening.

[0015] Optionally, the driving assembly includes a servo motor mounted on the frame and a second lead screw mounted on the output shaft of the servo motor; the feeding base is threadedly connected to the second lead screw, and a sliding groove is provided on the side wall of the frame, with the feeding base slidably connected to the sliding groove; the fixing assembly includes two second fixing cylinders hinged to the outer wall of the feeding tube, and a clamp is hinged to the piston rod of each second fixing cylinder, the two clamps being able to press the outer wall of the bag opening tightly against the outer wall of the feeding tube.

[0016] By adopting the above technical solution, when it is necessary to drive the feeding base to move, the servo motor is started first. At this time, the output shaft of the servo motor drives the second lead screw to rotate, and the rotation of the second lead screw can drive the feeding base to move. When it is necessary to install the bag opening onto the outer wall of the feeding tube, the two second fixing cylinders are started first. At this time, the piston rods of the two second fixing cylinders drive the two clamps to rotate in opposite directions, so that the bag opening can be installed onto the outer wall of the feeding tube.

[0017] Optionally, the hanging mechanism includes four hanging seats installed on the side wall of the unloading base. Each hanging seat has a hanging cylinder hinged to its bottom. The piston rod of the hanging cylinder is hinged to a hook. The four hooks are hung on the four lifting lugs one by one.

[0018] By adopting the above technical solution, when it is necessary to lift the four lifting lugs, the four hanging cylinders are first activated. At this time, the piston rods of the four hanging cylinders drive the four hooks to rotate, thereby lifting the four lifting lugs. In summary, the hanging mechanism is designed to facilitate the lifting of the four lifting lugs.

[0019] Optionally, a first anti-collapse mechanism is installed on the material feeding base. The first anti-collapse mechanism includes two horizontal plates respectively installed on the outer side walls of both sides of the material feeding base. A first horizontal cylinder is installed on the top of each horizontal plate. A moving plate is installed on the piston rod of the first horizontal cylinder. A vertical cylinder is installed on the moving plate. A vertical seat is installed on the piston rod of the vertical cylinder. A vertical rod is installed at the bottom of the vertical seat. A notch is provided at the joint of the two clamps to allow the vertical rod to pass through.

[0020] By adopting the above technical solution, when the clamp loosens the bag opening and the feeding base moves upward, the vertical cylinder is activated first. At this time, the piston rod of the vertical cylinder drives the vertical rod to move downward and insert into the bag opening. Then, the two first horizontal cylinders are activated. At this time, the piston rods of the two first horizontal cylinders drive the two vertical rods to move in opposite directions, thereby supporting the bag opening in the horizontal direction and reducing the possibility of the bag opening collapsing.

[0021] Optionally, a second anti-collapse mechanism is installed on the frame. The second anti-collapse mechanism includes two second horizontal cylinders installed on the frame. The piston rod of each second horizontal cylinder is fixedly connected to a first clamping plate. A guide rod is fixedly connected to the side wall of the first clamping plate. A guide tube for guiding the guide rod is installed on the side wall of the frame. Two third horizontal cylinders are respectively hinged to the side walls on both sides of the frame. The piston rod of each third horizontal cylinder is hinged to a second clamping plate.

[0022] By adopting the above technical solution, the first and second clamps can be set to limit the ton bag around its perimeter, thereby reducing the possibility of the ton bag collapsing.

[0023] Optionally, the feeding mechanism includes a feeding plate mounted on the top of the frame, a guide rail fixed to the top of the feeding plate, a feeding seat slidably connected to the guide rail, a feeding motor mounted on the top of the feeding seat, a gear mounted on the output shaft of the feeding motor, and a rack fixed to the top of the feeding plate; the gear meshes with the rack; two feeding cylinders are symmetrically hinged to the top of the feeding seat, and the piston rod of each feeding cylinder is hinged to a clamping rod, and the two clamping rods can clamp the bag opening.

[0024] By adopting the above technical solution, when it is necessary to feed the ton bags, the two feeding cylinders are started first. At this time, the piston rods of the two feeding cylinders drive the two clamping rods to rotate in opposite directions. The rotation of the two clamping rods in opposite directions can clamp the bag mouth. Then, the conveyor line and the feeding motor are started synchronously. At this time, the output shaft of the feeding motor drives the gear to rotate. Then, the feeding seat moves synchronously with the conveyor line under the action of the rack, so it is convenient to send the ton bags filled with materials out of the conveyor line at the same time.

[0025] In summary, this application includes at least one of the following beneficial technical effects: First, the ton bag is placed in the ton bag placement area. Then, the bag mouth is clamped by the bag mouth clamping mechanism. Next, a robotic arm transports the ton bag to the bag mouth support base. Then, a fixing mechanism secures the bag mouth, followed by the bag mouth clamping mechanism releasing the bag mouth. Next, a pulling mechanism pulls the bag mouth open, followed by a supporting mechanism to open the bag mouth. Then, the supporting mechanism sends the ton bag to the feeding base. Next, a drive assembly drives the feeding base to move downwards, driving the feeding pipe to insert into the bag mouth. Then, a fixing assembly secures the bag mouth, followed by the supporting mechanism releasing the bag mouth. Then, air is inflated into the ton bag through the inflation pipe, followed by the lifting mechanism lifting the lifting lugs. Next, material is injected into the ton bag through the discharge pipe of the hopper, and finally, a feeding mechanism sends the full ton bag to the transport line. This completes the ton bag packaging process. In summary, by adopting the above technical solution, the labor intensity of operators can be reduced. Attached Figure Description

The piston rod of the vertical cylinder 74 drives the vertical rod 76 to move downward and insert into the bag opening 12. Then, the two first horizontal cylinders 72 are activated. The piston rods of the two first horizontal cylinders 72 drive the two vertical rods 76 to move in opposite directions, thereby supporting the bag opening 12 in the horizontal direction and reducing the possibility of the bag opening 12 collapsing.

[0047] Reference Figures 7-9 A second anti-collapse mechanism 8 is installed on the frame 2. The second anti-collapse mechanism 8 includes two second horizontal cylinders 81 installed on the frame 2. The piston rod of each second horizontal cylinder 81 is fixedly connected to a first clamping plate 82. A guide rod 83 is fixedly connected to the side wall of the first clamping plate 82. A guide tube 84 for guiding the guide rod 83 is installed on the side wall of the frame 2. Two third horizontal cylinders 85 are respectively hinged to the side walls on both sides of the frame 2. The piston rod of each third horizontal cylinder 85 is hinged to a second clamping plate 86. The multiple second horizontal cylinders 81 and the multiple third horizontal cylinders 85 are all synchronously controlled by a controller, which can be a PLC. The first clamping plate 82 and the second clamping plate 86 are set to limit the ton bag 1 around its perimeter, thereby reducing the possibility of the ton bag 1 collapsing.

[0048] Reference Figures 7-9The feeding mechanism 9 includes a feeding plate 91 mounted on the top of the frame 2, a guide rail 92 fixed to the top of the feeding plate 91, a feeding seat 93 slidably connected to the guide rail 92 in a horizontal direction, a feeding motor 94 mounted on the top of the feeding seat 93, a gear mounted on the output shaft of the feeding motor 94, and a rack 96 horizontally fixed to the top of the feeding plate 91; the gear 95 is not shown in the figure, and the gear meshes with the rack 96; two feeding cylinders 97 are symmetrically hinged to the top of the feeding seat 93, and the piston rod of each feeding cylinder 97 is hinged to a clamping rod 98, and the two clamping rods 98 can clamp the bag opening 12; the multiple feeding cylinders 97 are synchronously controlled by a controller, which can be a PLC. When it is necessary to feed the ton bag 1, first start the two feeding cylinders 97. At this time, the piston rods of the two feeding cylinders 97 drive the two clamping rods 98 to rotate in opposite directions. The rotation of the two clamping rods 98 in opposite directions can clamp the bag opening 12. Then, the conveyor line 23 and the feeding motor 94 are started synchronously. At this time, the output shaft of the feeding motor 94 drives the gear 95 to rotate. Then, the feeding seat 93 moves synchronously with the conveyor line 23 under the action of the rack 96, so that the ton bag 1 filled with material can be sent out from the conveyor line 23 synchronously.

[0049] Working principle: First, the ton bag 1 is placed in the ton bag placement area 22. Then, multiple sets of first suction cup assemblies 32 adsorb the front of the bag opening 12. Next, the piston rod of the clamping cylinder 33 drives the gripper 34 to rotate, thereby pressing against the back of the bag opening 12, thus clamping the bag opening 12. Next, the robotic arm 31 drives the bag opening clamping mechanism to the support plate 421. Then, the first fixing cylinder 422 is activated. At this time, the piston rod of the first fixing cylinder 422 drives the pressure plate 423 to press the bag opening 12. After the pressure plate 423 presses the bag opening 12, the bag opening clamping mechanism releases the bag opening 12. Then, the opening cylinder 432 is activated. At this time, the piston rod of the opening cylinder 432 drives the second suction cup assembly 433 to move closer to the bag opening 12. The movement proceeds in two directions. Next, two sets of second suction cup assemblies 433 adhere to both sides of the bag opening 12. Then, by pulling the piston rod of the cylinder 432, the two sets of second suction cup assemblies 433 move in opposite directions, thus opening the bag opening 12. Then, by extending the piston rod of the cylinder 45, the flipping frame 451 rotates downwards. The downward rotation of the flipping frame 451 causes the two spreading plates 453 to rotate downwards, allowing the two spreading plates 453 to rotate into the bag opening 12. Next, the second drive motor 46 is activated. At this time, the output shaft of the second drive motor 46 drives the double threaded screw 461 to rotate. The rotation of the double threaded screw 461 drives the two connecting seats 457 to move in opposite directions. The two connecting seats 457 moving in opposite directions drive the two spreading plates 453 to move in opposite directions, thus opening the bag opening 12. The bag opening 12 is opened, and then the limiting cylinder 454 is activated. The piston rod of the limiting cylinder 454 drives the limiting rod 455 to rotate, limiting the outer wall of the bag opening 12. Next, the first drive motor 441 is activated. The output shaft of the first drive motor 441 drives the first lead screw 442 to rotate. The rotation of the first lead screw 442 drives the opening seat 444 to move, which in turn moves the ton bag 1, facilitating its transport to the discharge pipe 52. Next, the servo motor 531 is activated. The output shaft of the servo motor 531 drives the second lead screw 532 to rotate. The rotation of the second lead screw 532 drives the discharge base 51 to move downwards. The downward movement of the discharge base 51 drives the discharge pipe 52 to insert into the bag opening 12. When it is necessary to install the bag opening 12... When the material reaches the outer wall of the discharge pipe 52, the two second fixed cylinders 541 are activated first. At this time, the piston rods of the two second fixed cylinders 541 drive the two clamps 542 to rotate in opposite directions, so that the bag opening 12 can be installed on the outer wall of the discharge pipe 52. Then the two expansion plates 453 disengage from the bag opening and return to their original positions. Next, the ton bag is inflated through the inflation pipe, and then the four hanging cylinders 62 are activated. At this time, the piston rods of the four hanging cylinders 62 drive the four hooks 63 to rotate, so that the four lifting lugs 11 can be lifted. Next, the material is injected into the ton bag 1 through the discharge pipe of the hopper 21. The conveyor line 23 can move synchronously with the feeding mechanism 9. Then the feeding mechanism 9 sends the ton bag 1 filled with material out of the conveyor line 23, thus completing the packaging of the ton bag 1.In summary, by adopting the above technical solutions, the labor intensity of operators can be reduced.
