Description

Technical Field

[0001] The present invention relates to the technical field of tray cleaning, and particularly to a tray cleaning and transfer device. Background Art

[0002] The raw plasma used for plasma pharmaceuticals is usually collected in plasma bags, frozen into a frozen state, placed on trays, and sent to a cold storage for freezing and preservation. When in use, according to the production plan, the trays loaded with frozen plasma are taken out of the cold storage and sent to the feeding link. After completing the plasma feeding process, the emptied trays are not discarded but need to be transported back to the tray cold storage in a timely and orderly manner for storage and standby.

[0003] From the start of plasma warehousing to the completion of a full turnover of the tray and its re-warehousing, the entire operation cycle is quite long, about 6 months. During this period, the tray is not in an ideal aseptic environment throughout the process. Especially before plasma feeding, the tray needs to enter the pre-thawing room and stay there for 12 hours for slow thawing to facilitate subsequent accurate feeding. The environment in the pre-thawing room is relatively complex, and the temperature and humidity conditions are significantly different from those in the cold storage. Under the influence of such an environment, the tray is extremely vulnerable to varying degrees of contamination. There is often a small amount of plasma remaining at the tube head position of the plasma bag. As the temperature rises, this residual plasma gradually melts and flows down the bag tube to the surface of the tray. Over time, it not only dirties the tray but also provides a "breeding ground" for the growth of microbial pathogens, greatly increasing the risk of microbial contamination and potentially threatening subsequent batches of plasma.

[0004] Currently, before the tray is transported back to the tray cold storage, the cleaning method adopted is manual wiping. However, the plasma tray is designed in a relatively special way, with an uneven surface. To better fix the plasma bag, there are dozens of grooves with different depths and shapes. This uneven structure makes the manual cleaning work extremely difficult. By manpower, it is impossible to clean every corner of each groove and the bottom surface of the tray comprehensively, resulting in extremely unstable quality of manual cleaning, making it difficult to effectively ensure the cleanliness of the tray, and the cleaning efficiency is low. Summary of the Invention

[0005] To solve the technical problem that the tray for carrying plasma bags is uneven and manual cleaning cannot clean every corner and the bottom surface of the tray thoroughly, the present invention provides a tray cleaning and transfer device.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows: A tray cleaning and transfer device includes a tray transportation mechanism. The tray transportation mechanism includes a first conveyor roller group. In front of the first conveyor roller group, there is a second conveyor roller group. One end of the second conveyor roller group extends into the interior of the first conveyor roller group. There is a first conveying track on the side of the second conveyor roller group, and a second conveying track in front of the second conveyor roller group. The second conveying track has the same conveying direction as the second conveyor roller group. The first conveying track and the second conveying track are connected. There is a vertical disk mechanism movably arranged in the first conveying track. The vertical disk mechanism can move on the first conveying track and the second conveying track. The vertical disk mechanism includes a moving bracket. At the top of the moving bracket, there is a rotatable rotating shaft. The length direction of the rotating shaft is parallel to the conveying direction of the first conveyor roller group. There is a limiting fork on the upper surface of the rotating shaft. An automatic cleaning mechanism is arranged in the extending direction of the second conveying track. After plasma is fed, the empty tray is placed on the first conveyor roller group and transported to the narrower second conveyor roller group. The two sides of the tray extend out of the second conveyor roller group. At this time, the moving bracket is located in the first conveying track, and the limiting fork is placed horizontally. When the tray is transported to the second conveyor roller group, one side of the tray can enter the horizontally placed limiting fork. The rotating shaft rotates to make the limiting fork vertical, and the tray is erected. The moving bracket moves into the second conveying track, and moving along the second conveying track can ensure that the tray can enter the automatic cleaning mechanism in a vertical posture, enabling the automatic cleaning mechanism to clean every corner and the bottom of the tray.

[0007] As a preferred implementation of a tray cleaning and transfer device, there is a tray stacking mechanism at the end of the second conveying track far from the first conveyor roller group. The tray stacking mechanism includes a third conveyor roller group. The third conveyor roller group is the same as the second conveying track. The third conveyor roller group is located on the extension line of the second conveying track. There is a third conveying track on the side of the third conveyor roller group. The third conveying track is connected to the second conveying track. The vertical disk mechanism can move on the second conveying track and the third conveying track. There is a telescopic frame in the direction away from the second conveying track of the third conveyor roller group. The telescopic frame can telescopically extend vertically. There are several vertically and evenly arranged tray placing protrusions connected to both sides inside the telescopic frame. Two opposite tray placing protrusions form a pair. There is a tray placing plate on each pair of tray placing protrusions. Adjacent tray placing plates are connected by a vertical tray placing connecting plate. The cleaned tray enters the tray stacking mechanism through the second conveying track. The telescopic frame can telescopically extend vertically according to the quantity and height requirements of the trays. When the tray is placed on the tray placing plate, the adjacent tray placing plates are connected by the tray placing connecting plate, and multiple trays can be neatly stacked. This greatly improves the space utilization rate of tray storage, facilitates the centralized storage and management of the cleaned trays, and at the same time avoids the damage caused by the random stacking of trays during storage, provides an orderly storage method for the subsequent use of trays, and also facilitates the staff to quickly pick up trays according to production needs.

[0008] As a preferred implementation of a pallet cleaning and transporting device, both ends of the rotating shaft are rotatably mounted on a mobile bracket, the outer surface of one end of the middle part of the rotating shaft is sleeved with a driven gear, and a limit fork is installed on the upper surface of the other end of the middle part of the rotating shaft. A driving gear is provided inside the mobile bracket, and the driving gear is located below the driven gear. A rotating motor 1 is provided inside the mobile bracket, and the output shaft of the rotating motor 1 is connected to the gear shaft of the driving gear. When one side of the pallet enters the horizontally placed limit fork, the rotating motor 1 is started, driving the driving gear to rotate, and then driving the driven gear to rotate the rotating shaft, realizing the vertical flipping of the limit fork, and standing up the pallet. It can ensure the reliability and stability of the uprighting action of the pallet during the transportation process, avoid the pallet from falling or tilting due to unstable flipping, improve the safety of the pallet during transportation, and ensure that the pallet can accurately enter the automatic cleaning mechanism according to the predetermined process. At the same time, the motor drive is more efficient and labor-saving than manual operation.

[0009] As a preferred implementation of a pallet cleaning and transfer device, the automatic cleaning mechanism includes a high-pressure cleaning chamber 1, which is a U-shaped structure and is located above a conveying track 2. A high-pressure water tank 1 and a high-pressure water pump 1 are connected to each other on the top of the high-pressure cleaning chamber 1. The top and side of the inner wall of the high-pressure cleaning chamber 1 are provided with a plurality of high-pressure nozzles, and the high-pressure nozzles are connected to the high-pressure water pump through a pipeline pre-buried inside the high-pressure cleaning chamber 1. The high-pressure water pump 1 pressurizes the water in the high-pressure water tank 1 and sprays it out through the high-pressure nozzle to form a high-pressure water flow, which can strongly flush the surface of the pallet. It can effectively remove large stains, residual plasma and other pollutants attached to the surface of the pallet, especially for stubborn stains on the surface and grooves of the pallet. The high-pressure water flow can penetrate deep into the groove for cleaning, which makes up for the defect that manual wiping is difficult to clean deep in the groove, greatly improves the cleanliness of the pallet surface, and provides a good foundation for subsequent further cleaning processes.

[0010] As a preferred implementation of a pallet cleaning and transporting device, the automatic cleaning mechanism includes a spray disinfection chamber, which is a U-shaped structure and is located above the conveying track 2. The spray disinfection chamber is located in the direction away from the conveying roller group 1 of the high-pressure cleaning chamber 1. The top of the spray disinfection chamber is provided with a connected disinfectant storage box and a metering pump. The top and side of the inner wall of the spray disinfection chamber are provided with a plurality of atomizing nozzles, and the atomizing nozzles and the metering pump are connected through a pipeline pre-buried in the spray disinfection chamber. The metering pump can accurately control the flow of the disinfectant so that the disinfectant forms fine droplets through the atomizing nozzle and is evenly sprayed on the surface of the pallet. The pallet after high-pressure cleaning can be fully disinfected, and the microbial pathogens growing on the surface of the pallet can be effectively killed, so as to further ensure the cleanliness and hygiene of the pallet, prevent microorganisms from contaminating subsequent batches of plasma, improve the sanitary safety standards in the production process of plasma medicines, and ensure that the entire production process meets strict sanitary regulations.

[0011] As a preferred implementation of a tray cleaning and transfer device, the automatic cleaning mechanism includes a brush roll cleaning chamber. The brush roll cleaning chamber is of a U-shaped structure and is located above the second conveying track. The brush roll cleaning chamber is in the direction away from the first high-pressure cleaning chamber of the spray disinfection chamber. At the top of the inner wall of the brush roll cleaning chamber, two brush roll bodies are installed. The two brush roll bodies are located on both sides of the limit fork. The top end of each brush roll body is connected to the output shaft of the second rotating motor. The top of the second rotating motor is movably installed on the top of the inner wall of the brush roll cleaning chamber. The moving direction of the second rotating motor is perpendicular to the second conveying track. The brush roll cleaning chamber is located in front of the spray disinfection chamber. The two brush roll bodies installed on the top of the inner wall can rotate at high speed under the drive of the second rotating motor. The brush roll bodies are used to brush the surface and grooves of the tray. Especially for the fine stains remaining after high-pressure cleaning and spray disinfection, the brush roll bodies can completely remove them through the friction of the bristles. The second rotating motor can move along the direction perpendicular to the second conveying track on the top of the inner wall of the brush roll cleaning chamber, so that the brush roll bodies can comprehensively brush different positions of the tray, further improving the refinement degree of tray cleaning, ensuring that all corners of the tray can be deeply cleaned, and effectively solving the cleaning problem of the tray groove corners that are difficult to clean manually.

[0012] As a preferred implementation of a tray cleaning and transfer device, the automatic cleaning mechanism includes a second high-pressure cleaning chamber. The second high-pressure cleaning chamber has the same structure as the first high-pressure cleaning chamber. The second high-pressure cleaning chamber is in the direction away from the spray disinfection chamber of the brush roll cleaning chamber. The tray that has been cleaned by the brush roll bodies is subjected to secondary high-pressure flushing again by using the high-pressure cleaning method. It can completely remove the stains that are brushed off but not washed away in time during the cleaning process of the brush roll bodies, and at the same time further remove the possible remaining bristles or other impurities, ensuring that there are no any residual pollutants on the tray surface, making the cleanliness of the tray reach a higher standard, providing a cleaner tray surface for the subsequent water removal and drying processes, and ensuring the cleaning effect of the tray in the whole cleaning process.

[0013] As a preferred implementation of a tray cleaning and transfer device, the automatic cleaning mechanism includes an air knife water removal chamber. The air knife water removal chamber is of a U-shaped structure and is located above the second conveying track. The air knife water removal chamber is in the direction away from the brush roll cleaning chamber of the second high-pressure cleaning chamber. A high-pressure blower is provided at the top of the air knife water removal chamber. The high-pressure blower is connected to two high-pressure air pipes. The two high-pressure air pipes extend into the interior of the air knife water removal chamber. Air knife bodies are provided on both sides of the inner wall of the air knife water removal chamber. The two air knife bodies are in one-to-one correspondence and communication with the two high-pressure air pipes. The high-speed air flow blown out by the air knife body can quickly blow off a large amount of water stains on the surface of the tray. Compared with natural drying or manual drying, the efficiency is greatly improved. Most of the water on the surface of the tray can be quickly removed, the remaining water stains on the tray are reduced, and the problem that the upper and lower trays freeze together due to the remaining water stains after the tray is transported back to the tray cold storage is avoided. At the same time, the risk of secondary pollution to the plasma bag caused by the melting of the remaining ice on the tray during the next use is also reduced, which lightens the burden on the subsequent drying process and improves the overall efficiency of tray processing.

[0014] As a preferred implementation of a tray cleaning and transfer device, the automatic cleaning mechanism includes a drying chamber. The drying chamber is of a U-shaped structure and is located above the second conveying track. The drying chamber is in the direction away from the air knife water removal chamber of the second high-pressure cleaning chamber. A blower and heating resistance wires are provided at the top of the drying chamber. The blower is connected to two hot air pipes. The heating resistance wires are sleeved on the outer surface of the hot air pipes and extend into the hot air pipes. The two hot air pipes extend into the interior of the drying chamber and are respectively located on both sides of the inner wall of the drying chamber. The two hot air pipes are both provided with hot air outlets facing the interior of the drying chamber. The drying chamber is located in front of the air knife water removal chamber. The blower at the top is used to blow air into the hot air pipes sleeved with heating resistance wires. After the heating resistance wires heat the air, the hot air blows towards the tray through the hot air outlets on the hot air pipes. It can thoroughly dry the tray with a small amount of remaining water after water removal by the air knife body, ensure that the tray is completely dry, and avoid various problems that may be brought by the remaining water stains, such as tray freezing, secondary pollution, etc. The dried tray can enter the tray cold storage for storage in a dry and clean state, providing good conditions for the reuse of the tray in the subsequent production process of plasma-based pharmaceutical products, ensuring the smooth progress of the production link, and improving the reliability of the entire production process.

[0015] As a preferred implementation of a tray cleaning and transfer device, a conveyor belt is provided in the direction away from the tray transportation mechanism of the tray stacking mechanism. A tray storage room is provided in the direction away from the conveyor belt of the conveyor belt. Slide rails are provided at the tops of the two opposite tray placement protrusions at the bottom. The slide rails are arranged along the conveying direction of the third conveying roller group. A chute is provided at the top of the slide rail. A slider is provided in the chute. The slider can move linearly along the chute. When the tray stacking mechanism is full of trays, the slider moves linearly along the slide rail to convey the tray placement plate forward, that is, in the direction of the conveyor belt. The tray placement plate can be gradually conveyed onto the conveyor belt and then conveyed into the tray storage room by the conveyor belt. Brief Description of the Drawings

The slider 38 passes through the chute downward and is connected to the nut, so that the slider 38 can move linearly along the chute.

[0029] Working process: After the plasma is fed, the empty tray is sent out from the pre-melting room 011 and then placed on the first conveying roller group 11. The first conveying roller group 11 transports the tray to the second conveying roller group 12. Since the width of the second conveying roller group 12 is relatively narrow, both sides of the tray protrude. At this time, the limiting fork 23 on the moving bracket 21 in the first conveying track 13 is in a horizontal state. When the tray is transported onto the second conveying roller group 12, one side of the tray enters the horizontally placed limiting fork 23. Then, the first rotating motor 26 drives the driving gear 25 to rotate. The driving gear 25 meshes with the driven gear 24, thereby causing the rotating shaft 22 to rotate, and the limiting fork 23 changes from horizontal to vertical, and the tray is erected. Subsequently, the moving bracket 21 moves into the second conveying track 14 and moves along the second conveying track 14 towards the cleaning mechanism.

[0030] The erected tray first enters the first high-pressure cleaning chamber 4. After the high-pressure water tank 41 pressurizes the water through the first high-pressure water pump 42, high-pressure water is sprayed onto the surface of the tray through the high-pressure nozzle 43 to conduct a preliminary flushing of the tray, removing most of the stains and impurities on the surface.

[0031] After coming out of the first high-pressure cleaning chamber 4, the tray enters the spraying and disinfection chamber 5. The disinfectant in the disinfectant storage tank 51 is transported to the atomizing nozzle 53 through the metering pump 52. The atomizing nozzle 53 atomizes the disinfectant and sprays it on the surface of the tray to conduct a disinfection treatment on the tray, killing the possible microbial pathogens.

[0032] After being disinfected, the tray enters the brush roller cleaning chamber 6. The two brush roller bodies 61 located at the top of the inner wall of the brush roller cleaning chamber 6 rotate driven by the second rotating motor 62 to brush the surface of the tray, further removing stubborn stains, especially the stains in the uneven parts and grooves on the surface of the tray. The second rotating motor 62 can move in a direction perpendicular to the second conveying track 14 to adjust the contact position and force between the brush roller body 61 and the tray to ensure the brushing effect.

[0033] After the brush roller body 61 is cleaned, the tray enters the second high-pressure cleaning chamber 7 and is rinsed with high-pressure water again to thoroughly rinse off the loosened stains during the brushing process, making the surface of the tray cleaner.

[0034] After two high-pressure cleanings, the tray enters the air knife water removal chamber 8. The high-pressure fan 81 supplies high-pressure air to the air knife body 83 through the high-pressure air duct 82. The air knife body 83 blows the high-pressure air towards the surface of the tray in the form of a high-speed air flow to remove most of the water stains on the surface of the tray, reducing the workload and time for subsequent drying.

[0035] Finally, the tray enters the drying chamber 9. The blower 91 blows air into the hot air duct 93, and the heating resistance wire 92 heats the air in the hot air duct 93. The hot air outlets 94 on the hot air duct 93 blow hot air towards the tray to dry the tray, ensuring the dryness of the tray surface, avoiding the upper and lower trays from freezing together after the residual water stains cause the tray to be transported back to the tray cold storage 013, and preventing the residual ice from melting during the next use and causing secondary pollution to the plasma bag.

[0036] The cleaned and dried tray continues to move along the conveying track two 14 and enters the tray stacking mechanism 3. The conveying roller group three 31 of the tray stacking mechanism 3 conveys the tray to the telescopic frame 33. The telescopic frame 33 can be vertically telescoped.
