Description

Technical Field

[0001] This invention relates to the field of medical waste container cleaning technology, and in particular to a container turning and drying mechanism for a medical waste container cleaning line. Background Technology

[0002] Medical waste, or medical waste for short, refers to waste generated by medical and health institutions during medical treatment, prevention, healthcare, and other related activities that possess direct or indirect infectiousness, toxicity, or other hazards. Due to the special nature of medical waste, it typically needs to be transported to centralized disposal sites for centralized incineration. During transportation, medical waste is packaged in special yellow bags and collected in transfer containers. During incineration, the packaging bags and medical waste are poured into the incinerator together. The transfer containers are cleaned and disinfected before being reused in the transportation process.

[0003] See Figure 1 , Figure 2 As shown, in the prior art, the cleaning and disinfection process of the medical waste transfer container 6 is as follows: First, the medical waste transfer container 6 is placed upside down on the medical waste transfer container cleaning line 5. It passes through the rinsing and disinfection area on the conveyor of the medical waste transfer container cleaning line 5 to complete the rinsing and disinfection process. After cleaning and disinfection, the inverted medical waste transfer container 6 is lifted up by the flipping and water-spinning robot 8 set at the output end of the medical waste transfer container cleaning line 5. Then, it is flipped and rotated at high speed to remove residual water from the container by water-spinning. After water-spinning, the medical waste transfer container 6 is placed back onto the medical waste transfer container cleaning line 5 in the correct position by the flipping and water-spinning robot 8. At the same time, the lid and the container body are automatically closed by the weight of the lid.

[0004] The problem with the existing technology is that a certain amount of water will accumulate on the outer periphery of the medical waste turnover container 6 after cleaning, especially on the outward-flared edge at the mouth of the container 6, the bottom of the container, and the lid. Therefore, during the process of lifting, turning, and splashing water from the medical waste turnover container 6, a large amount of residual water will splash everywhere. The residual water spills over a wide area and is likely to corrode the surrounding equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a medical waste turnover bucket turning and drying mechanism that minimizes the residual water spillage area when removing residual water from cleaned medical waste turnover buckets, and to provide at least one beneficial solution to one or more technical problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution.

[0007] A medical waste turnover container washing line uses a container turning and drying mechanism, which includes a medical waste turnover container conveyor line, a turning robot, and a drying device. The turning robot is used to turn over and transport the medical waste turnover containers washed on the medical waste turnover container washing line to the medical waste turnover container conveyor line. The drying device is correspondingly arranged with the medical waste turnover container conveyor line and is used to blow air and dry the outer circumference of the medical waste turnover containers conveyed on the medical waste turnover container conveyor line.

[0008] When applying the tilting and drying mechanism for a medical waste container cleaning line provided by this invention, the entire tilting and drying mechanism is set on one side of the medical waste container cleaning line. After being cleaned and output from the medical waste container cleaning line, the medical waste container is gripped by the tilting robot, tilted 180°, and placed on the medical waste container conveyor line for continued transport. When the tilted medical waste container passes through the drying device, the air nozzle blows air onto the outer circumference of the medical waste container to remove as much residual water droplets as possible. Compared with existing tilting and water-spinning robots, the tilting and drying mechanism for a medical waste container cleaning line provided by this invention can achieve the effect of removing residual water from the container wall without lifting the medical waste container with a water-spinning robot. This avoids the problems of large water spillage and uncontrollable spillage caused by lifting the medical waste container to splash water, effectively reducing the problem of water accumulation in the surrounding environment and corrosion of surrounding equipment caused by removing residual water from the medical waste container.

[0009] In one embodiment, the flipping manipulator has two gripping arms arranged opposite to each other. One end of each gripping arm is fixed to a rotating shaft. Gripping plates are respectively provided on the opposite sides of the two gripping arms. The two gripping plates move towards or away from each other under the drive of a corresponding first power mechanism to achieve the purpose of gripping and releasing the medical waste transfer bin. The rotating shaft rotates back and forth under the drive of a second power mechanism to realize the flipping of the gripped medical waste transfer bin.

[0010] Obviously, the specific structure of the flipping robot is not limited to the examples above. Those skilled in the art can use other known or future-realizable robot structures according to different actual needs, as long as they can reliably flip the medical waste container and prevent a large amount of water from spilling into the surrounding environment during the flipping process.

[0011] In one embodiment, the first power mechanism is a cylinder, the cylinder body is fixed on the clamping arm, the cylinder shaft passes through the clamping arm and is fixed to the clamping plate, and the clamping plate moves towards or away from each other through the extension and retraction of the cylinder shaft, thereby clamping or releasing the medical waste transfer container.

[0012] In one embodiment, the second power mechanism is a motor, and the output shaft of the motor is connected to the rotating shaft through a speed change mechanism. The rotating shaft is rotated back and forth by the forward and reverse rotation of the motor, thereby flipping the clamped medical waste turnover bucket.

[0013] The primary reason for using a cylinder for the first power mechanism and an electric motor for the second power mechanism is ease of assembly and technological maturity. Clearly, the choice of the first and second power mechanisms is not limited to the examples above.

[0014] In one embodiment, a rubber layer is provided on the clamping surface of the clamping plate, and a concave-convex structure is provided on the rubber layer. When clamping the medical waste transfer container, the concave-convex surface of the rubber layer contacts the outer wall of the medical waste transfer container.

[0015] By incorporating a rubber layer with an uneven structure, the uneven surface of the rubber layer contacts the outer wall of the medical waste container when it is clamped. This ensures the stability of the container during clamping and turning, and reduces the risk of damage due to excessive clamping force. In some embodiments, the rubber layer can be replaced by other existing or future known contact layers that can increase friction.

[0016] In one embodiment, a baffle is provided corresponding to the flipping robot arm. The baffle is positioned facing the flipping direction of the medical waste transfer bin to reduce splashing of water during the flipping process. At the same time, during the flipping process of the medical waste transfer bin, the opened lid will come into contact with the baffle. The baffle's stopping action can better ensure that the lid can be smoothly placed on the opening of the bin after the medical waste transfer bin is flipped.

[0017] In one embodiment, the drying device includes a blower, an air supply duct, and an air outlet nozzle. The blower is used to provide air for drying the medical waste transfer container. The air supply duct is connected between the blower and the air outlet nozzle. The air outlet nozzle is used to evenly spray the air for drying onto the medical waste transfer container to blow off water droplets on the outside of the medical waste transfer container and to dry it.

[0018] This invention removes residual water droplets from medical waste transfer containers by blowing air to dry them. Compared with the traditional method of lifting and flipping the medical waste transfer containers to shake off water, this method has a better water removal and drying effect and avoids the problems of large water accumulation and uncontrollable water spillage caused by shaking off water.

[0019] In one embodiment, there are three air outlet nozzles, which are respectively located on the top side and both sides of the conveying direction of the medical waste transfer bin. When the medical waste transfer bin passes the location of the air outlet nozzles, the three air outlet nozzles blow air onto the top and sides of the medical waste transfer bin. By setting air outlet nozzles in three directions—top, left, and right—optimal dewatering and drying effects can be achieved on the outer periphery of the medical waste transfer bin.

[0020] In one embodiment, three blowers are used, each connected to a corresponding air outlet nozzle; each blower is equipped with a corresponding blower start / stop control device. This allows different blowers to be started and stopped according to actual needs, thereby achieving different blowing and drying effects.

[0021] In one embodiment, a positioning device is provided at the output end of the medical waste turnover bin cleaning line. The positioning device is preferably a position sensor. When the position sensor detects that the medical waste turnover bin output from the medical waste turnover bin cleaning line has reached the gripping position of the flipping robot, the medical waste turnover bin cleaning line is controlled to stop conveying so that the flipping robot can accurately and reliably grip the medical waste turnover bin.

[0022] Obviously, the positioning device is not limited to the position sensor mentioned above. Depending on the actual needs, those skilled in the art may also choose other existing or future known positioning devices to replace it.

[0023] It should be noted that, in addition to the beneficial effects described above, other beneficial effects of the technical solution provided by this invention will become more apparent in the following description or be learned through practice. Attached Figure Description

[0033] The embodiments described in the following detailed description are not intended to limit the invention. Other embodiments and changes may be made without departing from the spirit or scope of the subject matter presented herein.

[0034] Although the present invention has been described in accordance with the best mode for achieving its objectives, those skilled in the art will recognize that several modifications may be made based on the teachings herein without departing from the spirit or scope of the invention.

[0035] Reference Figure 3 , Figure 4 As shown, a medical waste transfer container washing line uses a container turning and drying mechanism, including a turning manipulator 1 and a drying device 2. The turning manipulator 1 has two opposing clamping arms 101, one end of which is fixed to a rotating shaft 102. Clamping plates 103 are respectively provided on opposite sides of the two clamping arms 101. The two clamping plates 103 move towards or away from each other under the drive of a corresponding first power mechanism 104 to clamp and release the medical waste transfer container. The rotating shaft 102... Driven by the second power mechanism 105, it rotates back and forth to achieve the flipping of the clamped medical waste turnover bucket; the air drying device 2 includes a blower 201, an air supply duct 202, and an air outlet nozzle 203. The blower 201 is used to provide air for blowing and drying the medical waste turnover bucket. The air supply duct 202 is connected between the blower 201 and the air outlet nozzle 203. The air outlet nozzle 203 is used to evenly spray the air for blowing and drying onto the medical waste turnover bucket to blow off water droplets on the outside of the medical waste turnover bucket and dry it.

[0036] In this embodiment, the first power mechanism 104 is preferably a cylinder, and the second power mechanism 105 is preferably a motor. During assembly, the cylinder body is fixed on the clamping arm 101, and the cylinder shaft passes through the clamping arm 101 and is fixed to the clamping plate 103. The clamping or releasing of the medical waste transfer container is achieved by the extension and retraction of the cylinder shaft. The motor output shaft is connected to the rotating shaft 102 through a speed change mechanism. The rotation of the clamped medical waste transfer container is achieved by the forward and reverse rotation of the motor. The connection and installation of the power mechanism is very convenient.

[0037] It should be noted that the flipping robot 1 exemplified in this embodiment is only a preferred implementation. Those skilled in the art can make appropriate changes to the selection of the first power mechanism 104 and the second power mechanism 105, as well as the specific structural design of the flipping robot 1, according to different actual needs, as long as the purpose of stably and effectively flipping the medical waste turnover bucket 180° can be achieved.

[0038] Furthermore, in this embodiment, a rubber layer is provided on the clamping surface of the clamping plate 103, and an uneven structure is provided on the rubber layer. Since most medical waste containers are plastic containers, by providing a rubber layer with an uneven structure on the clamping surface of the clamping plate 103, when clamping the medical waste container, the uneven surface of the rubber layer contacts the outer wall of the medical waste container, which can ensure the stability of the medical waste container during clamping and flipping, and reduce the possibility of damage to the medical waste container due to excessive clamping force.

[0039] Combined Figure 3 As shown, a baffle 3 is also provided corresponding to the flipping robot 1. The baffle 3 is set in the direction of the flipping movement of the medical waste transfer bin 6 to reduce the splashing of water during the flipping process of the medical waste transfer bin 6. At the same time, during the flipping process of the medical waste transfer bin 6, the opened lid will come into contact with the baffle 3. Under the stopping action of the baffle 3, it can better ensure that the lid can be smoothly closed on the opening of the bin after the medical waste transfer bin 6 is flipped.

[0040] Combined Figure 4 As shown, there are three air outlet nozzles 203, which are respectively located on the top side and both sides of the medical waste transfer bin conveyor line 4 in the direction of travel. When the medical waste transfer bin passes the location of the air outlet nozzles 203, the three air outlet nozzles blow air onto the top and sides of the medical waste transfer bin to remove as much residual water droplets as possible. This achieves a similar technical effect to traditional water-spinning without the need for water-spinning. In some embodiments, a condensation device is also provided corresponding to the blower 201 to make the air blown from the blower cold and dry air, further improving the drying effect of water droplets on the medical waste transfer bin.

[0041] In this embodiment, there are three blowers 201, each corresponding to one of the air outlet nozzles 203; this allows different blowers to be activated as needed. In some embodiments, there is one blower 201, which provides airflow to the three air outlet nozzles 203 through a ductwork distribution method, but this is not limited to this embodiment.

[0042] Combination Figure 5 As shown in the figure, the working principle of the tipping and drying mechanism for the medical waste turnover bin cleaning line provided in this embodiment is as follows: The entire tipping and drying mechanism is set on one side of the medical waste turnover bin cleaning line 5. After the medical waste turnover bin 6 is cleaned and output from the medical waste turnover bin cleaning line 5, it is clamped by the tipping robot 1, flipped 180° and placed on the medical waste turnover bin conveyor line 4 for continued conveying. When the tipped medical waste turnover bin 6 passes through the drying device 2, the air nozzle 203 blows air on the outer periphery of the medical waste turnover bin to remove as much residual water droplets as possible from the medical waste turnover bin. In this way, the technical effect similar to traditional water-spinning can be achieved without water-spinning and the problem of residual water spilling over a large area due to water-spinning, which is easy to cause corrosion to surrounding equipment, is avoided.

[0043] To ensure that the flipping robot 1 can accurately grip the medical waste container, a positioning device 7 is also provided at the output end of the medical waste container washing line 5. The positioning device 7 is preferably a position sensor. When the position sensor detects that the medical waste container 6 output from the medical waste container washing line 5 has reached the gripping position of the flipping robot 1, it controls the medical waste container washing line 5 to stop conveying, so that the flipping robot 5 can accurately and reliably grip the medical waste container 6. In some embodiments, the position sensor can be replaced by other existing or future known positioning devices.

[0044] It should be noted that, in this invention, the fixing method of the clamping arm 101 and the rotating shaft 102, the connection method of the rubber layer and the clamping plate 103, the selection of the speed change mechanism, the control implementation of the flipping and clamping action of the flipping robot, the selection and control of the blower model, etc., are all common technical knowledge mastered by those skilled in the art, and will not be described in detail here.

[0045] It should also be noted that, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" in this invention should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0046] In this invention, unless otherwise specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "below," and "over" the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Above," "below," and "below" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

Improvements and substitutions made using techniques known in the art based on this invention all fall within the scope of protection of this invention, which should be defined by the claims and their equivalents. Parts not described in the specific embodiments are all prior art or common knowledge.
