Description

Technical Field

[0001] This disclosure pertains to the field of novel robots, specifically relating to a medical waste packaging device. Background Technology

[0002] In hospitals across the country and even the world, the generation and disposal of medical waste is unavoidable every moment. However, the proper and rigorous packaging and transportation of medical waste is an easily overlooked process. Medical waste must be packaged using swan-neck knots, requiring specialized medical waste bag handlers. Extensive research has revealed that there are currently no automated machines for swan-neck knot packaging of medical waste bags. Furthermore, current medical waste carts only collect medical waste and do not perform swan-neck knot packaging. In addition, while there are automatic packaging bins for household use, they seal the bags using thermoplastic sealing, which is unsuitable for medical waste that may contain sharp objects and requires a high degree of airtightness. Given the increasing public concern about the safety of medical waste packaging and transportation, and considering the significant uncertainties of manual packaging and the risk of infection to the packaging personnel from medical waste during the process, this issue remains a significant concern.

[0039] In one embodiment, such as Figure 1 , Figure 2 As shown, this disclosure provides a medical waste bag packaging device, comprising:

[0040] The device body 3, wherein a packaging mechanism is provided inside the device body 3, the packaging mechanism includes a packaging chamber 32, and the packaging chamber 32 is provided with:

[0041] The binding module 6 is used to bind the garbage bags to be collected.

[0042] Knob module 7 is used to operate the knob on the garbage bag after the opening is closed;

[0043] The ring-adding module 8 is used to add a ring to the garbage bag behind the knob;

[0044] Bending module 9 is used to bend the garbage bag after the ring is added;

[0045] The shrinking module 10 is used to shrink the garbage bag after it has been bent.

[0046] The above embodiments constitute the complete technical solution of this disclosure. The device described in this embodiment can automatically perform special packaging processing operations on medical waste bags that comply with national and industry standards, thereby avoiding the possibility of infection by medical waste during manual packaging.

[0047] In another embodiment, such as Figure 4 As shown, the junction module 6 includes a push rod assembly and a first slide groove assembly.

[0048] In this embodiment, the slide rail assembly includes a first slide rail 65, a second slide rail 66, a third slide rail 67, and a fourth slide rail 68, which are mechanically fixed to the packaging chamber by screws. The push rod assembly includes a first push rod 61, a second push rod 62, a third push rod 63, and a fourth push rod 64, each push rod being individually connected to a stepper motor. One end of the first push rod 61 and the third push rod 63 are located in the first slide rail 65, and the other end is located in the second slide rail 66. Driven by the stepper motor, as... Figure 5 As shown, the first push rod 61 and the third push rod 63 slide relative to each other along the first slide groove 65 and the second slide groove 66. One end of the second push rod 62 and the fourth push rod 64 are both located in the third slide groove 67, and the other end is both located in the fourth slide groove 68. Driven by the stepper motor, the second push rod 62 and the fourth push rod 64 slide relative to each other along the third slide groove 67 and the fourth slide groove 68. When the first and third push rods, and the second and fourth push rods, slide relative to each other to a preset minimum distance driven by the stepper motor, the garbage bag is finished to be sealed.

[0049] In another embodiment, such as Figure 4 As shown, the knob module 7 includes a gear gripper assembly and a motor.

[0050] In this embodiment, the motor includes a first motor 73 and a second motor 74. The first motor 73 is mounted on the second motor 74. A first gear gripper 71 is provided on one side of the first motor 73, and a second gear gripper 72 is provided on the other side. After the bag opening is tightened by the drawstring module, the first gear gripper 71 and the second gear gripper 72 rotate vertically upward under the drive of the first motor 73 to tighten the bottom of the garbage bag. Subsequently, the first gear gripper 71 and the second gear gripper 72 move circumferentially from 1440° to 1800° under the drive of the second motor 74, causing the garbage bag to rotate, thereby making the upper part of the garbage bag into a twisted shape that conforms to industry standards.

[0051] In another embodiment, such as Figure 3 , Figure 6 and Figure 7 As shown, the ring-adding module 8 includes: a ring storage chamber 82, a packing groove 81 below the ring storage chamber 82, a crank slider 83 on the inner wall of the ring storage chamber 82, a push plate 84 connected to the crank slider, and the push plate 84 is set on the inner wall of the packing chamber by a spring.

[0052] In this embodiment, the push plate 84, under the elastic force of the spring, pushes the nylon cable tie in the storage ring chamber 82 into the slot of the packing groove, thereby limiting the nylon cable tie. Then, the crank slider 83 is driven by the stepper motor to reciprocate, so as to press the nylon cable tie located at the slot into the packing groove 81, providing the prerequisite for the subsequent binding of the upper part of the twisted garbage bag with nylon cable ties.

[0053] In another embodiment, such as Figure 4 As shown, the bending module 9 includes: a second slide rail assembly, on which a top rod 91 is provided.

[0054] In this embodiment, one end of the push rod 91 is placed in the fifth slide groove 92, and the other end is placed in the sixth slide groove 93. When the upper part of the garbage bag is twisted into a spiral shape by the knob module, the push rod slides along the fifth and sixth slide grooves under the drive of the stepper motor, pushing the upper part of the garbage bag into the packing slot, thereby simulating the process of bending the upper part of the twisted garbage bag into a "gooseneck" during the garbage bag packing process.

[0055] In another embodiment, such as Figure 8 As shown, the shrinking module 10 includes: a telescopic frame 102, which is installed on the inner wall of the packing slot by screws, and the telescopic frame 102 is connected to an eccentric ratchet 101 by a stepper motor.

[0056] In this embodiment, after the upper part of the garbage bag is pushed into the packing slot by the top rod 91, the telescopic frame 102 extends under the drive of the stepper motor to send the eccentric ratchet 101 into the bottom of the packing slot. The eccentric ratchet 101 rotates under the drive of the stepper motor, causing the nylon cable tie knob to tighten. When the nylon cable tie is tightened, the top rod 91 retracts. At the same time, the first gear pawl 71 and the second gear pawl 72 are released, and the first push rod 61, the second push rod 62, the third push rod 63 and the fourth push rod 64 retract along the slide groove respectively.

[0057] In another embodiment, the device further includes a control module.

[0058] In this embodiment, the control module includes a memory and a processor. The memory stores multiple computer instructions, and the processor executes the computer instructions to control each motor to drive the above-mentioned modules to perform corresponding actions.

[0059] In another embodiment, a sterilizer 5 is also provided in the packaging room.

[0060] In this embodiment, the sterilizer stores disinfectant, and the garbage bag is disinfected by spraying the disinfectant during the packaging process.

[0061] In another embodiment, the device body also includes a storage mechanism.

[0062] In this embodiment, the storage mechanism includes a storage chamber 31, within which a sensor 311 is installed. The sensor detects the height of the waste bags within the storage chamber and provides feedback to the control module. When the storage chamber is not full of medical waste, the sensor 311 scans the next waste storage point and sends its location back to the control module. The control module performs real-time path planning based on the location of the waste storage point. Once the path planning is complete, a movement command is issued, causing the casters mounted on the chassis to move the waste storage point under the drive of a motor. When the sensor 311 detects that the medical waste in the storage chamber has reached a preset height, it again sends feedback to the control module. The control module then randomly issues a stop waste collection command. At this time, the casters, driven by the motor, move towards the pre-stored coordinates of the waste collection point in the control module.

[0063] In another embodiment, the device body is externally provided with a gripping module.

[0064] In this embodiment, the gripping module includes a first robotic arm 1 and a second robotic arm 2. The first robotic arm is located at the top of the device body and includes a first rotating joint 11, a second rotating joint 12, a third rotating joint 13, a fourth rotating joint 14, a fifth rotating joint 15, a sixth rotating joint 16, and a first robotic gripper 17. Each pair of adjacent joints from the first to the sixth rotating joints, as well as the sixth rotating joint and the first robotic gripper, are connected via servo motors. The second robotic arm is located at the side of the device body and includes a seventh rotating joint 21, an eighth rotating joint 22, a ninth rotating joint 23, a tenth rotating joint 24, an eleventh rotating joint 25, a twelfth rotating joint 26, and a second robotic gripper 27. Similarly, each pair of adjacent joints from the seventh to the twelfth rotating joints, as well as the twelfth rotating joint and the second robotic gripper, are connected via servo motors. Through the cooperation of the first and second robotic arms, the packaged garbage bags in the packaging chamber can be transferred to the storage chamber.

[0065] In another embodiment, the device body includes a housing, a chassis 4 is provided at the bottom of the housing, and casters 41 are provided on the chassis 4.

[0066] In this embodiment, a vision sensor 33 is installed outside the box. The vision sensor 33 can collect information about the surrounding medical waste storage points in real time and feed the information back to the control module, thereby enabling the device to perform path planning.

[0067] All the above embodiments constitute the complete technical solution of this disclosure. The packaging device described in this solution can automatically package medical waste into bags, which improves the efficiency of waste packaging and greatly reduces the probability of infection for personnel packaging medical waste. Furthermore, it should be noted that this technical solution, in addition to packaging medical waste, can also package items requiring sealing, providing convenience for production and daily life, and meeting standards or requirements.
