Description

Technical Field

[0001] The utility model relates to the technical field of automatic bagging equipment, in particular to a bagging machine. Background Art

[0002] In modern pharmaceutical, food, electronics, and other industries with stringent packaging requirements, drug bag packaging is a crucial step in ensuring product quality. Traditional drug bag packaging processes typically rely on manual labor, where workers manually place the drug bags into outer packaging bags, then place the filled outer bags into a vacuum heat sealer to complete the vacuuming and heat sealing steps. This method of operation has many shortcomings, primarily reflected in the following aspects:

[0003] First, manual operation is inefficient. In large-scale production, the bagging, vacuuming, and heat-sealing processes require significant manual effort, increasing labor costs and limiting production speed. As production demands increase, manual operation is no longer sufficient for high-volume, high-efficiency production.

[0004] Secondly, manual operation has poor accuracy and consistency. Due to the different operating habits and proficiency of each worker, the speed and quality of bagging vary, which may cause some bags to be filled irregularly, thus affecting the vacuuming and heat sealing effects, and reducing the packaging quality of the final product.

[0005] Thirdly, manual operation can easily introduce contamination. During the bagging process, the medicine bags are exposed to the external environment, and workers may also touch the medicine bags during operation, which poses a certain risk of contamination. This is particularly detrimental to some pharmaceutical packaging processes that have strict environmental requirements.

[0006] To address these issues and improve the automation of pharmaceutical bag packaging, many companies have begun introducing automated equipment, such as fully automatic bagging machines. These machines automatically complete operations such as bagging, vacuuming, and heat sealing, significantly improving production efficiency and packaging quality while reducing the risk of contamination caused by manual intervention.

[0007] However, existing fully automatic bagging equipment still has some shortcomings, such as complex structure, difficult commissioning and maintenance, and the possibility of equipment failure after long periods of high-intensity operation, affecting production continuity. Therefore, developing a fully automatic bagging machine with a simple structure, stable operation, and easy maintenance has become a key requirement for improving the automation level of the pharmaceutical bag packaging process.

[0008] In summary, in response to the shortcomings of the existing technology, a new type of fully automatic bagging machine is proposed to solve the problems of low efficiency, unstable quality, high contamination risk, etc. existing in manual operation. Utility Model Content

[0052] Among them, frame A9 and frame B10 are the basic supporting structures of the entire bagging machine. Frame A9 is mainly used to support and install the bag pushing mechanism, empty bag conveying mechanism 4, bag taking mechanism 5, bag opening mechanism 6, plastic sealing mechanism 7 and bag pressing mechanism 8028. Frame B10 is used to support the material sorting mechanism 1 and the material sorting conveying mechanism 2. Frame A9 and frame B10 are fixed by mechanical connection to form an integral mechanical frame structure.

The material handling robot 101 is mounted on a frame B10, and the medicine bag conveyor belt 102 is disposed below the material handling robot 101. The medicine bag conveyor belt 102 is connected to the frame B10 via feet, and a visual inspection device 103 is disposed above the medicine bag conveyor belt 102. The material handling robot 101 is responsible for grabbing medicine bags from the medicine bag conveyor belt 102 and placing them on the material handling conveyor mechanism 2. Using a robotic arm or other automated equipment, the material handling robot 101 can quickly and accurately locate and transfer medicine bags, reducing the time and labor intensity of manual operations while improving production efficiency. The medicine bag conveyor belt 102 is used to transport medicine bags from upstream processes or loading locations to the working area of ​​the material handling robot 101. The conveyor belt ensures a continuous supply of medicine bags, enabling the sorting robot 101 to perform its grasping tasks consistently and efficiently. A visual inspection device 103, mounted above the medicine bag conveyor belt 102, is responsible for inspecting parameters such as the bags' appearance, position, and quality. Using image recognition technology, the visual inspection device 103 can screen out unqualified medicine bags, such as those that are damaged, defective, or incorrectly positioned, ensuring that only those that meet the standards are grasped and conveyed to the next process by the sorting robot 101. Through the precise operation of the sorting robot 101, the medicine bags are delivered to the sorting conveyor mechanism 2 in the correct orientation and position. Accurate positioning of the medicine bags during the sorting phase helps reduce deviations and errors in subsequent processes, ensuring the smooth progress of the entire packaging process.

[0054] The material handling and conveying mechanism 2 includes a first transmission shaft assembly 201, a bracket assembly 202, a second transmission shaft assembly 203, a synchronous belt assembly 204, and a servo motor 205. The first transmission shaft assembly 201 is installed at the head end of the bracket assembly 202, and the second transmission shaft assembly 203 is installed at the end of the bracket assembly 202. The synchronous belt assembly 204 is tensioned and installed between the first transmission shaft assembly 201 and the second transmission shaft assembly 203. The servo motor 205 is installed on the bracket assembly 202, and the servo motor 205 is connected to the first transmission shaft assembly 201 through a belt rotation. The material handling and conveying mechanism 2 realizes the smooth conveyance of the medicine bags through the synchronous belt assembly 204. The synchronous belt assembly 204 is tensioned and installed between the first transmission shaft assembly 201 and the second transmission shaft assembly 203. It can ensure that the medicine bag remains stable during the transportation process without sliding or offsetting, and ensure that the medicine bag can accurately reach the designated position; the servo motor 205 provides power and is connected to the first transmission shaft assembly 201 through a belt to drive the synchronous belt assembly 204 to operate. The precise control of the servo motor 205 can adjust the transportation speed and positioning accuracy as needed to ensure that the medicine bag moves according to a predetermined rhythm and path; since the servo motor 205 has the characteristics of programmable control, the material handling and conveying mechanism 2 in this embodiment can adapt to medicine bags of different specifications, sizes or types, and different production requirements can be met by simply adjusting the parameters of the servo motor 205; the material handling and conveying mechanism 2 ensures that the medicine bag can be smoothly transferred to the pushing mechanism 3 after being grasped by the material handling robot 101, thereby ensuring seamless connection between working processes.

[0055] The pushing mechanism 3 includes a pushing frame 301, a linear rail, and a pushing plate. The pushing frame 301 is installed on the frame A9, the linear rail is installed on the pushing frame 301, and the pushing plate is arranged on the linear rail slider; the pushing plate can move accurately along the linear rail by being installed on the linear rail slider. The pushing plate is responsible for pushing the medicine bag from the end of the material handling and conveying mechanism 2 into the opened outer packaging bag, ensuring that the medicine bag can enter the outer packaging bag correctly and smoothly, and avoiding the medicine bag from being skewed or stuck during the pushing process; the linear rail of the pushing mechanism 3 ensures the stability and linearity of the pushing plate when pushing the medicine bag, avoiding the possibility of offset or misalignment; through the fixed installation of the pushing frame 301 and the guiding effect of the linear rail, the pushing mechanism 3 can maintain a consistent movement trajectory and force in each operation, ensuring that each medicine bag can be pushed into the outer packaging bag in the same way and angle.

[0056] The empty bag conveying mechanism 4 includes a conveying frame 401 and a servo active component 402. The conveying frame 401 is installed on the frame A9, and the servo active component 402 is installed on the conveying frame 401 to provide power for the conveying belt; the conveying frame 401 supports and fixes the entire conveying mechanism to ensure that the outer packaging bags can be smoothly transported from the storage position to the designated workstation, avoiding displacement, folding or damage of the empty bags, and ensuring that the outer packaging bags can smoothly enter the next process; the servo active component 402 is responsible for providing power for the conveying belt. Through the precise control of the servo motor 205, the conveying belt can transport the empty bags to the correct position at an appropriate speed; the empty bag conveying mechanism 4 cooperates with the bag taking mechanism 5 and the bag opening mechanism 6. The bag taking mechanism 5 takes out the outer packaging bags from the bag bin component 503 and places them on the conveying belt, while the empty bag conveying mechanism 4 transports these outer packaging bags to the position of the bag opening mechanism 6, ready for bag opening and medicine bag filling operations.

[0057] The bag taking mechanism 5 includes a bag taking frame 501, a bag taking moving component 502, and a bag bin component 503. The bag taking frame 501 is installed on the frame A9, the bag taking moving component 502 is installed on the bag taking frame 501, and the bag bin component 503 is installed below the bag taking moving component 502; the bag bin component 503 is used to store neatly arranged empty outer packaging bags, and the bag taking moving component 502 takes out the outer packaging bags one by one from the bag bin component 503 through automated operation, reducing dependence on manual operation, and the bag taking moving component 502 accurately places the taken out outer packaging bags on the conveyor belt of the empty bag conveying mechanism 4, and the bag taking mechanism 5 works closely with the empty bag conveying mechanism 4 to ensure that the outer packaging bags can enter the conveying process in time. The accurate operation of the bag taking moving component 502 enables the outer packaging bags to enter the conveyor belt smoothly and perform subsequent packaging operations in sequence.

[0058] The bag-opening mechanism 6 includes a bag-opening assembly, a mainboard bracket, and a bag-stretching assembly 605. The mainboard bracket is mounted on the machine frame A9, the bag-opening assembly is mounted on the mainboard bracket, and the bag-stretching assembly 605 is mounted below the bag-opening assembly. The bag-opening assembly is responsible for opening the delivered outer packaging bag. It can grasp and separate the sealed portion of the outer packaging bag, opening the bag mouth to allow the medicine bag to be smoothly loaded. The bag-stretching assembly 605 is mounted below the bag-opening assembly and is responsible for stretching and maintaining the opening of the opened outer packaging bag. This ensures that the outer packaging bag does not close or deform during the loading process, providing a stable opening for smooth and accurate loading of the medicine bag. The bag-opening mechanism 6, through the combined action of bag-opening and bag-stretching, ensures that the outer packaging bag is in the optimal open state, allowing the medicine bag to be accurately loaded into the bag. The bag-opening mechanism 6 closely cooperates with the pushing mechanism 3 to ensure that the pushing mechanism 3 can smoothly push the medicine bag into the bag while the outer packaging bag is opened. The bag support assembly 605 keeps the bag opening stably open, making the pushing process smoother, thereby ensuring that the medicine bag can accurately enter the bag and avoid any obstruction or damage.

[0059] The plastic sealing mechanism 7 includes a bag pressing and plastic sealing upper component 701, a vacuuming component 702, and a bag pressing and thermoplastic component 703. The bag pressing and plastic sealing upper component 701 is installed at the upper end of the vacuuming component 702, the bag pressing and thermoplastic component 703 is installed at the lower end of the vacuuming component 702, and the bag pressing and thermoplastic component 703 is installed at the end of the empty bag conveying mechanism 4; the vacuuming component 702 extracts the air in the outer packaging bag to form a vacuum environment in the bag to prevent oxidation, moisture and other environmental factors from affecting the medicine. The bag pressing and thermoplastic component 703 performs heat sealing on the outer packaging bag. The heat sealing heats the material of the sealing bag opening to fuse it together to form a sealed seal. This sealed seal ensures that the outer packaging bag can remain sealed after the vacuuming process and prevents air from re-entering the bag, thereby ensuring the quality and safety of the medicine bag. The bag pressing and plastic sealing upper component 701 is installed at the upper end of the vacuuming component 702 and is used to compact the bag opening before heat sealing. The coordinated operation of the various sub-mechanisms within the plastic sealing mechanism 7 ensures the continuity and efficiency of the entire vacuum packaging and sealing process. First, the vacuum pumping component 702 is responsible for exhausting the air in the bag, then the bag pressing and plastic sealing upper component 701 performs the compaction operation, and finally the bag pressing and thermoplasticizing component 703 completes the heat sealing.

[0060] The bag pressing mechanism 8028 includes a bag pressing transverse movement component 801, a bag pressing frame, and a plastic sealing air control box 803. The bag pressing transverse movement component 801 is mounted on the bag pressing frame, which is mounted on frame A9, and the plastic sealing air control box 803 is mounted on the bag pressing frame. The bag pressing transverse movement component 801 compacts the vacuum-sealed outer packaging bag through mechanical transverse movement. While compacting the bag, the bag pressing transverse movement component 801 also reshapes the bag to make it flatter and more regular. Through compaction, the outer packaging bag becomes tighter and stronger, enhancing its pressure resistance. The plastic sealing air control box 803 is mounted on the bag pressing frame and is responsible for controlling the pneumatic devices related to bag pressing and plastic sealing. It ensures that the pneumatic operation of the bag pressing transverse movement component 801 and other related mechanisms can be precisely controlled, ensuring the stability and consistency of the bag pressing and sealing operations.

[0069] The first transmission shaft assembly 201 includes a transmission shaft 206, a driving pulley 207, two driven pulleys 208, bearings, spacers, and seated bearings. The driving pulley 207 is located in the center, while the driven pulleys 208 are located on either side. The servo motor 205 drives the driving pulley 207 to control the speed of the center timing belt assembly 204. The second transmission shaft assembly 203 is generally similar in structure to the first transmission shaft assembly 201, differing in that the center contains the driven pulley 208, while the two driving pulleys 207 are driven by the servo motor 205 to control the speed of the timing belt assemblies 204 on both sides.

[0070] The synchronous belt assembly 204 includes a synchronous belt and a synchronous assembly. The synchronous assembly is installed on the synchronous belt. The synchronous assembly includes a first synchronous assembly 209-a third synchronous assembly, wherein the first synchronous assembly 209 serves as a bottom support for the medicine bag and is evenly distributed on the three synchronous belts; the second synchronous assembly 210 serves as a limiter and is evenly distributed on the middle synchronous belt and is controlled by the middle synchronous belt; the third synchronous assembly serves as a limiter and is installed on the synchronous belts on both sides. The gap between the second synchronous assembly 210 and the third synchronous assembly serves to fix the medicine bag. Therefore, the second synchronous assembly 210 and the third synchronous assembly can complete the effect of automatic distance limiting under the control of the servo motor 205 combination, and can adapt to a variety of medicine bags.

[0071] refer to Figure 4 The pushing mechanism 3 proposed in this embodiment includes a pushing frame 301 installed on the frame A9, a linear rail assembly 302 is installed on the pushing frame 301, and a push plate assembly 303 is installed on the slider of the linear rail assembly 302.

[0072] refer to Figure 5 The empty bag conveying mechanism 4 proposed in this embodiment includes a conveying frame 401 installed on the frame A9, and a servo active component 402 installed on the conveying frame 401 to provide power for the conveying belt.

[0073] Among them, a vacuum device is set under the conveyor frame 401, and the upper cover is designed with slots. Similarly, the conveyor belt is also designed with air holes. When the empty bag is placed on the conveyor belt, the vacuum device starts to adsorb the empty bag and the displacement of the empty bag affects the bagging and heat sealing effects.

[0074] refer to Figure 6 The bag taking mechanism 5 proposed in this embodiment includes a bag taking frame 501, which is installed on the frame A9, a bag taking moving component 502 is installed on the bag taking frame 501, a bag bin component 503 is installed below the bag taking moving component 502, and a bag bin lifting component 504 is installed on the back of the bag taking frame 501.

The bag suction component 505 is installed on the servo sliding guide rail component, and the suction plate is controlled by the cylinder to suck the bag downward. When the bag is successfully adsorbed, the cylinder is retracted, and at the same time, the bag picking moving component 502 controls the bag suction component 505 to move toward the empty bag conveying component. The bag bin component 503 is installed on the bottom plate below the bag picking frame 501, and a servo screw rod is provided at the bottom to control the width of the bag bin component 503 to adapt to various specifications of outer bags. The bag bin lifting assembly 504 is connected to the bottom plate of the bag bin assembly 503, and the rise and fall of the bottom plate of the bag bin assembly 503 is controlled by the servo screw assembly. The top of the bag bin assembly 503 is sensed by photoelectric sensing. When the top bag is sucked away, the photoelectric sensing cannot sense the bag and sends a signal to control the servo motor 205 to drive the bag bin assembly 503 to rise. When the bag is sensed, the servo motor 205 stops moving, and the bag supply is realized in this reciprocating manner. That is, the bag taking moving assembly 502 controls the empty bag to move from the bag bin assembly 503 to the conveyor belt, and the bag suction assembly 505 sucks the bag. The bag bin assembly 503 has the function of automatically rising to supply bags and automatically adjusting the width of the bag bin assembly 503.

The suction cup bag opening assembly 604 is installed on the third main board 603. The cylinder controls the suction cup to move up and down to complete the bag opening action. A fixed suction cup is designed below the suction cup bag opening combination, and bag holding assemblies 605 are arranged on both sides of the fixed suction cup. The bag holding assembly 605 controls the left and right movement of the bag holding paddle through the servo motor 205, and the rotating cylinder controls the gathering and opening of the paddle.

[0079] Among them, the bag pressing and plastic sealing upper component 701 includes a first heat sealing component 704, a bag opening cylinder component 705, a straightening component 706 and an installation main board 707. The first heat sealing component 704 includes a heat sealing plate component, a sealing plate component, and a bag opening suction cup component. The heat sealing plate component is driven downward by the cylinder to drive the heat sealing plate, the sealing plate component is opened, and the bag opening suction cup component is also driven by the cylinder. The straightening component 706 is driven by the cylinder finger to clamp the bag, and the screw slide rail controls the left and right movement of the straightening component 706.

[0080] The vacuum assembly 702 includes a duckbill straw assembly 708, an opening blade assembly 709, and a mounting plate. The duckbill straw assembly 708 includes a control cylinder and a duckbill straw. The control cylinder uses compressed air to push the piston inside it, thereby generating linear reciprocating motion. The duckbill straw is connected to the end of the piston rod of the control cylinder. When the piston rod moves in the control cylinder, it drives the duckbill straw to extend or retract accordingly. The opening blade assembly 709 includes a control cylinder, a servo slide assembly, and an opening blade. The opening blade is fixed to a bracket, which is fixed to the end of the piston rod of the cylinder by bolts or other connection methods.

[0081] The bag pressing thermoplastic component 703 includes a servo slide rail component, a second heat sealing component and a mounting plate. The second heat sealing component includes a silicone strip and a silicone strip mounting plate.

[0082] The outer packaging bag is first opened by the bag opening assembly, and then the duckbill straw assembly 708 and the opening blade assembly 709 are inserted into the outer bag. After the opening blade assembly 709 straightens the bag opening, the sealing plate moves downward to press the bag while the vacuum straw starts to draw vacuum. After the vacuum is drawn, the vacuum straw is retracted and the heat sealing plate presses the bag downward to heat seal it.

The lifting servo motor 1004 drives the synchronous belt to move, and drives the aluminum profile 1005 to move up and down along the longitudinal slide rail 1006 through the synchronous belt buckle. The suction cup assembly 1008 is fixedly connected to the lifting assembly, and the lifting assembly drives the suction cup assembly 1008 to move up and down. The transverse movement assembly moves along the transverse slide rail 1003 to the position of the medicine bag conveyor line to push the material. The aluminum profile 1005 is connected to the suction cup assembly 1008, and the lifting assembly controls the suction cup assembly 1008 to descend to the surface of the medicine bag. The suction cup assembly 1008 adsorbs the medicine bag through a vacuum pump or other adsorption device. The lifting assembly controls the suction cup assembly 1008 to be lifted to a suitable height to ensure that the medicine bag is firmly adsorbed, and then the medicine bag is transported back to the push bin to complete the pushing into the bag.

[0089] In this embodiment, suction cup assembly 1008 is connected to a vacuum generator. When the vacuum generator is activated, the air inside the suction cup is extracted, creating a low-pressure state. The pressure differential between the suction cup and the contact surface of the medicine bag generates a suction force, thereby firmly grasping the medicine bag. The core of this embodiment lies in the coordinated operation of the transverse movement assembly and the lifting assembly, and how to achieve efficient transportation of medicine bags from the conveyor line to the push hopper. The specific structure of the suction cup assembly is a mature technology widely used in industrial automation equipment. It only serves as an auxiliary tool to absorb the medicine bag, so it will not be described in detail.
