The counting sensor can also be configured as any other sensor with counting function.

[0080] Compared with the prior art, the present embodiment provides a counting device 4 between the separation and reflux device 3 and the discharge device 5, which can accurately count the materials that are to be conveyed to the discharge device in a specific posture.

[0081] The material feeding device 5 includes a first material feeding component 501, a second material feeding component 502, a material storage component 503, and a sliding component 504.

[0082] Optionally, the first material feeding component 501 is configured as two fixed hoppers and located below the end of the first conveying component 401; the second material feeding component 502 is configured as a hopper that moves with the sliding component 504 and is located below the first material feeding component 501; both the first material feeding component 501 and the second material feeding component 502 are provided with the material storage component 503 at their bottoms for controlling the storage and release of materials.

[0083] Specifically, the material storage component 503 of the feeding device 5 is electrically connected to the control system and is initially in a closed state. When the counting device 4 counts to the set quantity, the feeding device 5 starts to work. First, the control system sends a signal to control the feeding device 2, the separation and return device 3, and the counting device 4 to stop working, while controlling the gripping device 6 to work in conjunction with the feeding device 5. Second, the control system sends a signal to control the second feeding component 502 to move directly below one of the hoppers of the first feeding component 501 and open the material storage component 503 of the first feeding component 501. Similarly, the material in the other hopper of the first feeding component 501 is also dropped into the second feeding component 502. Then, the control system controls the second feeding component 502 to move directly above the packaging bag and open the material storage component 503 to complete the feeding operation.

[0084] Optionally, the second material feeding component 502 is configured with a reasonable motion trajectory plan; the initial position of the second material feeding component 502 is directly below one of the hoppers of the first material feeding component 501, the first target position is directly below the other hopper of the first material feeding component 501, and the second target position is directly above the packaging area; the sliding component 504 drives the second material feeding component 502 to move between the initial position, the first target position, and the second target position.

[0085] Compared with the prior art, the present embodiment provides a method that uses two fixed hoppers, one movable hopper, a material storage component, and a gripping device to work together, which can improve the efficiency of the material dropping process. At the same time, the control system controls the operation of each component, which can realize automatic material dropping and ensure the stability of the material dropping process.

[0086] The gripping device 6 includes a dual robotic arm 601 and a single robotic arm 602, each with a suction cup at its end. The dual robotic arm 601 is used to pick up, move, and open the packaging bag; the single robotic arm 602 is used to pick up and place the certificate of conformity. Both the dual robotic arm 601 and the single robotic arm 602 are two-degree-of-freedom robotic arms and are equipped with a reasonable recognition and detection algorithm for identifying the packaging bag and the certificate of conformity.

[0087] Optionally, the dual manipulator 601 consists of a rotary drive mechanism 601a, a linear drive mechanism 601b, and an end effector with a suction cup 601c; the rotary drive mechanism 601a includes any mechanism capable of driving the manipulator to rotate, such as a rotary cylinder or a rotary electric cylinder; the linear drive mechanism 601b includes any mechanism capable of driving the manipulator to move linearly, such as a dual-rod dual-axis cylinder or an electric push rod.

[0088] Specifically, the rotary drive mechanism 601a and the linear drive mechanism 601b are used to drive the dual robotic arms 601 to rotate and move linearly, and the end suction cup 601c is used to pick up the packaging bag and cooperate with the flaring mechanism to flare the packaging bag during the flaring process.

[0089] Optionally, the end effector with a suction cup generates a negative pressure vacuum through a vacuum generator, so that when the suction cup contacts the packaging bag or certificate of conformity, it adsorbs the packaging bag or certificate of conformity through vacuum pressure; a one-way valve, an energy storage device, a solenoid valve, and an air filter are also connected between the vacuum generator and the suction cup; the one-way valve is used to ensure a vacuum environment; the solenoid valve is used to maintain and release the vacuum; the air filter is used to prevent dust, oil, and other small particles from entering the vacuum system.

[0090] Specifically, when the dual robotic arms 601 detect that there are no packaging bags in the packaging area but there are packaging bags in the packaging bag storage area, the control system controls one of the dual robotic arms 601 to move to the packaging bag storage area to pick up the packaging bag using a suction cup, and then move it to the packaging area; then the suction cups and gripping devices of the dual robotic arms 601 work together to open the packaging bag opening; finally, when the single robotic arm 602 detects that there are no certificates of conformity in the packaging bags in the packaging area but there are certificates of conformity in the certificate of conformity storage area, the control system controls the single robotic arm 602 to move to the certificate of conformity storage area to pick up the certificate of conformity using a suction cup, and then move it directly above the packaging bag; then the certificate of conformity is placed into the packaging bag; after the picking and placing work is completed, the single robotic arm 602 automatically returns to the certificate of conformity storage area to wait for the next picking and placing cycle.

[0091] Compared with the prior art, the present embodiment provides a control system that controls the gripping device to automatically complete the picking up of packaging bags, picking up of certificates of conformity and placing them, avoiding problems such as missing or placing too many certificates of conformity, while saving costs; the design of the linear drive mechanism and suction cups can effectively pick up packaging bags of different heights and thicknesses.

[0093] Specifically, the sealing device 7 is electrically connected to the control system. When the material feeding is completed, the control system sends a signal to control the electric heating device 701 in the sealing device 7 to heat to the set temperature, thereby completing the automatic sealing of the packaging bag.

[0094] Compared with the prior art, the present embodiment provides a method for sealing packaging bags by controlling an electric heating device through a control system, thereby achieving safe and stable sealing of packaging bags.

[0095] The sorting device 8 includes a left conveyor belt 801 and a right conveyor belt 802, which are used to transport the packaging bags to the designated location after automatic sealing.

[0096] Specifically, when the unloading operation begins, the left conveyor belt lifts the packaging bag to a set height. After the unloading and sealing operations are completed, the left conveyor belt descends to the initial height and is driven by a motor to transport the sealed packaging bag to the designated position before stopping its rotation. This allows the bag to fall onto the rotating right conveyor belt, which then transports the packaging bag to the designated storage container, completing the sorting operation.

[0097] Optionally, the packaging machine provided in this embodiment also includes a human-machine interaction device, which is equipped with a touch screen for manually setting the feeding speed, counting quantity and running time in each operation such as automatic feeding, automatic counting and automatic unloading.

[0099] Example 2

[0100] This application also provides an industrial automated rapid packaging method, such as... Figure 9 As shown, the process includes feeding, separation and recirculation, counting, gripping, unloading, sealing, and sorting steps. Specifically,

[0101] Feeding process: The control system drives the second conveying component to rotate clockwise by controlling the motor, which conveys the material in the storage bin to the third conveying component;

[0102] Separation and return step: The control system drives the third conveying component to rotate clockwise by controlling the motor. The material on the third conveying component is adjusted in posture by the stabilizing component and then separated by the separation component. The material that does not conform to the specific posture is returned to the storage bin, and the material that conforms to the specific posture is conveyed to the counting device.

[0103] Counting steps: After the first conveying component receives the material that meets the specific posture from the third conveying component, it calculates the quantity of material conveyed to the unloading device by the counting device at the end of the first conveying component and uploads it to the control system.

[0104] Grasping steps: First, check if there is a packaging bag. If so, the control system drives the dual robotic arms to pick up the packaging bag via motors; otherwise, execute an emergency stop. Second, determine if the packaging bag has been effectively picked up. If it has, the motors drive the dual robotic arms to move and open the packaging bag; otherwise, execute an emergency stop. Next, determine if the packaging bag has been effectively opened. If it has, a single robotic arm checks for a certificate of conformity; otherwise, execute an emergency stop. If a certificate of conformity is present, the single robotic arm picks up the certificate. Finally, determine if the certificate of conformity has been effectively picked up. If it has, the motors drive the single robotic arm to place the certificate into the packaging bag; otherwise, execute an emergency stop.

[0105] Material feeding process: When the counting device reaches the preset quantity, the feeding device starts working. The control system stops the feeding device and the counting device, and simultaneously moves the second feeding component below the first feeding component, opening the storage component of the first feeding component. The second feeding component then begins collecting the material from the first feeding component. After completing the collection task, the storage component of the first feeding component is closed, and the second feeding component moves directly above the packaging bag, opening its storage component to allow the material to fall into the packaging bag containing the certificate of conformity. After completing the feeding task, the storage component of the second feeding component is closed, and the control system resumes operation of the feeding device and the counting device.

[0106] Sealing steps: The control system sends a signal to control the electric heating device in the sealing device to heat to the set temperature, and automatically seals the packaging bag;

[0107] Sorting steps: After the packaging bags are sealed, the control system controls the motor to drive the two conveyor belts of the sorting device to transport the packaging bags to the designated location.

It should be understood that the above description is only a specific embodiment of this application and is not intended to limit the scope of protection of this application.
