Description

Technical Field

[0001] This utility model belongs to the field of bottled or cylindrical dual-compartment sorting technology, and relates to a dual-compartment feeding and conveying mechanism of an automatic vacuum blood collection tube sorting device. Background Technology

[0002] After blood is collected from a patient, medical staff need to use a handheld scanner to scan the barcode information and sort the blood collection tubes according to the information returned by the hospital or laboratory information management system. This facilitates the subsequent testing of the blood collection tubes for different items. Automatic blood collection tube sorting devices, developed to reduce sorting error rates, improve sorting efficiency, and reduce labor costs, often encounter situations where different batches of blood collection tubes have different sorting priorities. Some blood collection tubes added later to the sorting device often need to be prioritized. Most existing blood collection tube sorting devices use a single-hopper feeding mode, where all tubes are placed in the same hopper, and different batches of blood collection tubes are randomly sorted, failing to meet priority requirements. Therefore, a dual-hopper feeding and conveying mechanism is needed for an automatic vacuum blood collection tube sorting device suitable for scenarios where different batches of blood collection tubes have a specific sorting order. This mechanism can sort higher-priority blood collection tubes first, and then proceed with the sorting of lower-priority blood collection tubes after all higher-priority tubes have been sorted. Summary of the Invention

[0003] To overcome the shortcomings of existing blood collection tube sorting devices that cannot allocate different batches of blood collection tubes according to priority standards, this utility model provides a dual-compartment feeding and conveying mechanism for an automatic vacuum blood collection tube sorting device that can prioritize the allocation of higher priority batches.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A dual-compartment feeding and conveying mechanism for an automatic vacuum blood collection tube sorting device includes a conveying unit, a feeding unit, and a hopper unit. The feeding unit is located within the hopper unit, and its outlet is connected to the inlet of the conveying unit. One feeding unit and one hopper unit form a set of storage and feeding modules. The dual-compartment feeding and conveying mechanism includes a left storage and feeding module and a right storage and feeding module arranged side by side. The left storage and feeding module has a lower priority than the right storage and feeding module. Each right storage and feeding module is equipped with a first feeding sensor. The module is equipped with a second feeding sensor. Both the first and second feeding sensors are connected to the dual-compartment feeding control unit. In the dual-compartment feeding control unit, when the first feeding sensor detects a blood collection tube in the compartment, the right compartment feeding module is started for feeding and transmission. At this time, the left compartment feeding module is not started regardless of whether the second feeding sensor detects a blood collection tube in the compartment. When the first feeding sensor does not detect a blood collection tube in the compartment, it is then determined whether the second feeding sensor has detected a blood collection tube in the compartment. If it has, the left compartment feeding module is started for feeding and transmission.

[0006] Furthermore, the feeding unit includes a feeding base plate, a feeding side plate R, a feeding side plate L, a feeding stationary plate, a first adjusting block, a second adjusting block, a third adjusting block, a fourth adjusting block, a first moving plate mounting component, a second moving plate mounting component, a drive motor, a driving synchronous wheel, a driven synchronous wheel, a first moving plate, a second moving plate, a third moving plate, a fourth moving plate, a fifth moving plate, and a sixth moving plate. The feeding side plate R and the feeding side plate L are mounted on the feeding base plate; the feeding stationary plate is mounted on the feeding base plate; the first moving plate and the second moving plate are sequentially mounted on the first moving plate mounting component and the second moving plate mounting component, respectively; the third moving plate, the fourth moving plate, the fifth moving plate, and the sixth moving plate are sequentially mounted on the first adjusting block, the second adjusting block, the third adjusting block, and the fourth adjusting block, respectively; the first adjusting block and the third adjusting block are mounted on the first moving plate mounting component; the second adjusting block, the fourth moving plate, and the fifth moving plate are sequentially mounted on the first adjusting block, the second adjusting block, the third adjusting block, and the sixth moving plate are sequentially mounted on the first adjusting block, the second adjusting block, the third adjusting block, and the sixth moving plate, respectively. An adjusting block is mounted on the second moving plate mounting component. The first and second moving plate mounting components are mounted on a linear guide rail, which is mounted on the loading base plate. The active synchronous pulley is mounted on the output shaft of the drive motor, which is mounted on the loading motor mount, which is mounted on the loading base plate. The driven synchronous pulley is mounted on a cantilever pin, which is mounted on a cantilever pin seat, which is mounted on the loading base plate. The active and driven synchronous pulleys are connected by a synchronous belt, thereby the drive motor drives the active synchronous pulley to rotate, indirectly driving the synchronous belt to move. The synchronous belt is equipped with synchronous belt clamps, wherein the first synchronous belt clamp is connected to the first moving plate mounting component via a first connecting sheet metal, and the second synchronous belt clamp is connected to the second moving plate mounting component via a second connecting sheet metal, thereby driving each moving plate to move for loading.

[0007] Furthermore, the transmission unit includes a support profile, a circular belt driven pulley mounted on the support profile, a transmission circular belt, a circular belt driving pulley, a transmission circular belt motor, a flat belt driven pulley, a transmission flat belt, a flat belt main pulley, and a transmission flat belt motor. The circular belt driven pulley and the circular belt driving pulley are located on both sides of the support profile, which tighten the transmission circular belt. When the transmission circular belt motor is connected to the circular belt driving pulley and rotates, it drives the transmission circular belt to move, transmitting the blood collection tube to the rear flat belt section. The flat belt driven pulley, the transmission flat belt, the flat belt main pulley, and the transmission flat belt motor are configured in the same way to form a flat belt module, which transmits the blood collection tube to the push rod of the push rod unit.

[0008] The dual-compartment feeding and conveying mechanism also includes a blood collection tube pusher unit, which is installed at the rear end of the conveying unit and is used to stably push the blood collection tubes that have been fed to other modules for sorting.

[0009] The dual-compartment feeding and conveying mechanism also includes a blood collection tube roller seat unit, which is installed on the side and rear of the conveying unit to allow the blood collection tube to rotate to a suitable angle to cooperate with the barcode scanning device to scan and read the barcode.

[0010] The main advantages of this invention are as follows: Under normal conditions, blood collection tubes are placed into the outermost hopper (lower priority) for normal sorting. However, when higher priority batches of blood collection tubes need to be sorted, they are placed into the innermost hopper. At this time, the program controls the outer hopper to automatically stop feeding until the higher priority tubes are sorted, at which point the outer feeding device is restarted to continue the sorting process of lower priority blood collection tubes. The entire process requires no manual intervention, perfectly meeting the requirements for prioritizing the sorting of blood collection tubes that urgently need testing. Attached Figure Description

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] Reference Figures 1-5 A dual-compartment feeding and conveying mechanism for an automatic vacuum blood collection tube sorting device includes a conveying unit 44, a feeding unit 43, and a hopper unit 42. The feeding unit 43 is located inside the hopper unit 42, and the outlet of the feeding unit 43 is connected to the inlet of the conveying unit 44. One feeding unit 43 and one hopper unit 42 form a set of storage and feeding modules. The dual-compartment feeding and conveying mechanism includes a left storage and feeding module and a right storage and feeding module arranged side by side. The left storage and feeding module has a lower priority than the right storage and feeding module. The right storage and feeding module is equipped with a first feeding sensor 47. The storage and feeding module is equipped with a second feeding sensor 48. Both the first feeding sensor 47 and the second feeding sensor 48 are connected to the dual-compartment feeding control unit. In the dual-compartment feeding control unit, when the first feeding sensor 47 detects a blood collection tube in the compartment, the right storage and feeding module is started for feeding and transmission. At this time, the left storage and feeding module is not started regardless of whether the second feeding sensor 48 detects a blood collection tube in the compartment. When the first feeding sensor 47 does not detect a blood collection tube in the compartment, it is then determined whether the second feeding sensor 48 has detected a blood collection tube in the compartment. If it has, the left storage and feeding module is started for feeding and transmission.

[0020] Figure 1The assembly structure of the dual-bin feeding and conveying mechanism within the automatic blood collection tube sorting device is shown. The bin unit 42 and the feeding unit 43 constitute two sets of storage and feeding modules. Blood collection tubes are placed into the left bin unit. After the second feeding sensor 48 detects the blood collection tube, it controls the second feeding motor 6-2 to move the left feeding unit, conveying the blood collection tube horizontally from the transmission unit 44 into the push rod unit 45. The push rod then pushes the tube above the roller seat unit 46, where the rollers rotate in conjunction with the scanning device to complete the scanning. Finally, the push rod pushes the blood collection tube to other modules of the sorting device for sorting.

[0021] Figure 4 The control logic for dual-compartment feeding is illustrated. After a blood collection tube is placed into the left low-priority compartment, the second feeding sensor 48 detects the blood collection tube in the compartment and controls the second feeding motor 6-2 to drive the low-priority feeding unit to start feeding. When a higher-priority blood collection tube needs to be sorted first, it can be placed into the right compartment unit. After the first feeding sensor 47 senses the blood collection tube, it sends a response signal to the control module. Upon receiving the signal, the control module issues an instruction to stop the left compartment feeding module and waits for a preset time until some blood collection tubes from the transmission unit 44 leave the docking area with the right compartment unit 42. Then, it controls the first feeding motor 6-1 to drive the right feeding unit to sort the higher-priority blood collection tubes. This continues until the first feeding sensor 47 senses that there are no more blood collection tubes in the compartment. Finally, the control module issues an instruction to restart the left compartment feeding module to continue sorting the lower-priority blood collection tubes.

[0022] The feeding unit 43 includes a feeding base plate 29, a feeding side plate R20, a feeding side plate L31, a feeding stationary plate 21, a first adjusting block 15, a second adjusting block 16, a third adjusting block 17, a fourth adjusting block 18, a first moving plate mounting component 11, a second moving plate mounting component 13, a drive motor 6, a driving synchronous wheel 7, a driven synchronous wheel 2, a first moving plate 22, a second moving plate 23, a third moving plate 24, a fourth moving plate 25, a fifth moving plate 26, and a sixth moving plate 27. The feeding side plate R20 and the feeding side plate L31 are mounted on the feeding base plate 29. The loading plate 21 is mounted on the loading base plate 29; the first moving plate 22 and the second moving plate 23 are sequentially mounted on the first moving plate mounting part 11 and the second moving plate mounting part 13, respectively; the third moving plate 24, the fourth moving plate 25, the fifth moving plate 26, and the sixth moving plate 27 are sequentially mounted on the first adjusting block 15, the second adjusting block 16, the third adjusting block 17, and the fourth adjusting block 18, respectively. The first adjusting block 15 and the third adjusting block 17 are mounted on the first moving plate mounting part 11, and the second adjusting block 16 and the fourth adjusting block 18 are mounted on the second moving plate mounting part 11. On plate 13, the first moving plate mounting part 11 and the second moving plate mounting part 13 are mounted on the linear guide rail 10, and the linear guide rail 10 is mounted on the loading base plate 29; the driving synchronous wheel 7 is mounted on the output shaft of the drive motor 6, the drive motor 6 is mounted on the loading motor seat 8, and the loading motor seat 8 is mounted on the loading base plate 29; the driven synchronous wheel 2 is mounted on the cantilever pin 3, the cantilever pin 3 is mounted on the cantilever pin seat 1, and the cantilever pin seat 1 is mounted on the loading base plate 29; the driving synchronous wheel 7 and the driven synchronous wheel 2 are connected by the same... The synchronous belt 5 is connected, thereby driving the motor 6 to drive the active synchronous pulley 7 to rotate, indirectly driving the synchronous belt 5 to move; the synchronous belt 5 is equipped with a synchronous belt clamp 4, wherein the first synchronous belt clamp 4-1 is connected to the first moving plate mounting part through the first connecting sheet metal 12, and the second synchronous belt clamp 4-2 is connected to the second moving plate mounting part 13 through the second connecting sheet metal 14, thereby driving each moving plate to move and feed material; the hopper unit 42 is installed on the feeding unit 43, and two sets of identical hopper units 42 and feeding units 43 are close to the side of the docking transmission unit to form a feeding transmission process.

[0023] The blood collection tube sorting device using the dual-compartment feeding and conveying mechanism of this utility model also includes a blood collection tube push rod unit 45 and a blood collection tube roller seat unit 46.

[0024] The blood collection tube pusher unit 45 is installed at the rear end of the transmission unit 44 and is used to stably push the loaded blood collection tubes to other modules for sorting. Its working stroke can be freely adjusted by changing parameters according to actual needs.

[0025] The blood collection tube roller seat unit 46 is installed on the side and rear of the transmission unit 44, and is used to rotate the blood collection tube to a suitable angle to cooperate with the barcode scanning device to scan and read the barcode.

[0026] like Figure 3 As shown, the system includes a drive motor 6, whose body is mounted on the back of the loading base plate 29 via a loading motor seat 8, and a drive synchronous pulley 7 is mounted on its shaft end; the driven synchronous pulley 2 on the other side is mounted on the loading cantilever pin seat 1 via a loading cantilever pin 3, and then mounted on the back of the moving plate 29. The synchronous pulleys on both sides support the synchronous belt 5, and synchronous belt clamps 4 are mounted on both sides of the synchronous belt 5, so that when the loading drive motor 6 drives the drive synchronous pulley 7 to rotate, it can drive the synchronous belt clamps 4 on both sides to move up and down in opposite directions at the same speed, thus constituting the power source of the loading unit 43.

[0027] Figure 4 The structure of the transmission connection part of the feeding unit is shown. Two linear guide rails 10 are installed parallel to each other on the front of the feeding base plate 29. Each guide rail has three sliders mounted on it, connecting the upper, middle, and lower parts of the first moving plate mounting component 11 and the second moving plate mounting component 13, allowing them to slide up and down parallel to the feeding base plate 29 along the guide rail mounting direction. The first connecting sheet metal 12 and the second connecting sheet metal 14 are connected on one side to the back synchronous belt clamp 4, and on the other side to the first moving plate mounting component 11 and the second moving plate mounting component 13 respectively, so that the synchronous belt 5 in the back power module moves synchronously with them. The first adjusting block 15, the second adjusting block 16, the third adjusting block 17, and the fourth adjusting block 18 are sequentially installed in the middle of the second moving plate mounting component 13, the middle of the first moving plate mounting component 11, the bottom of the second moving plate mounting component 13, and the bottom of the first moving plate mounting component 11, located directly above the guide rail sliders. As shown in the figure, each adjusting block and the moving plate mounting component forms six mounting planes of different heights for the staggered installation of the moving plates. The fixed plate transition plate 9 is installed on the back of the feeding fixed plate 21 and is used to connect the transition feeding unit 43 and the transmission unit 44.

[0028] Figure 5 This is a complete three-dimensional view of the loading unit, including some control logic. The loading stationary plate 21 is mounted on the top front of the loading base plate 29, located at the bottom layer. The first moving plate 22 is mounted on the top of the first moving plate mounting piece 11, above the loading stationary plate 21, with a gap of approximately 1mm between the two plates. The second moving plate 23 is mounted on the top of the second moving plate mounting piece 13, above the first moving plate 22, with a gap of approximately 1mm between the two plates, and is connected to the first connecting sheet metal 12 with combination screws. The third moving plate 24 is mounted on the front of the first adjusting block 15, above the second moving plate 23, with a gap of approximately 1mm between the two plates, and is connected to the second connecting sheet metal 14 with combination screws. The fourth moving plate 25 is mounted on the front of the second adjusting block 16, above the third moving plate 24, with a gap of approximately 1mm between the two plates. The fifth moving plate 26 is mounted on the front of the third adjusting block 17, above the fourth moving plate 25, with a gap of approximately 1mm between the two plates. The sixth moving plate 27 is mounted on the front of the fourth adjusting block 18, above the fifth moving plate 26, with a gap of approximately 1mm between the two plates. Depend on Figure 2The installation relationship between the adjusting block and the moving plate mounting component is such that when the feeding drive motor 6 is running, the first moving plate 22, the third moving plate 24, and the fifth moving plate 26 move up and down with the first moving plate mounting component 11, while the second moving plate 23, the fourth moving plate 25, and the sixth moving plate 27 move up and down the same distance with the second moving plate mounting component 13 in the opposite direction to the moving plate 11. The feeding side plate L 31 and feeding side plate R 20 are installed on both sides of the feeding base plate 29. At the same time, the feeding side plate L 31 is equipped with a feeding sensor 32 at the bottom. When the sixth moving plate 27 moves upward and the sensor sensing plate 28 installed on its surface triggers the feeding sensor 32 above, the V-shaped low point at the top of the sixth moving plate 27 coincides with the inclined surface at the top of the fifth moving plate 26. The blood collection tube located at the top of the sixth moving plate 27 rolls to the top of the fifth moving plate 26. After the trigger signal of the feeding sensor 32 above is transmitted to the control module, the control module issues a reverse movement command to the feeding drive motor 6. The fifth moving plate 26 moves upward and the fourth moving plate 25 moves downward until the sensor sensing plate 28 below triggers the feeding sensor 32 below. The inclined surfaces at the top of the moving plate 5 and the fourth moving plate 25 coincide. By repeating the above process, the blood collection tube can be unified from a disordered state to a horizontal state and lifted to the transmission unit 44. The first PC baffle 30 and the second PC baffle 19 are installed on the top of the feeding side plate L 31 and the feeding side plate R 20. Together with the V-shaped structure at the top of the sixth moving plate 27, they prevent the blood collection tube from being lifted vertically to the transmission unit 44, ensuring that the lifting process is smooth and without any jamming.

[0029] Figure 6 The diagram shows the internal transmission structure of the transmission unit 44. The transmission unit 44 includes a support profile 35, a circular belt driven pulley 33 mounted on the support profile 35, a transmission circular belt 34, a circular belt driving pulley 36, a transmission circular belt motor 37, a flat belt driven pulley 38, a transmission flat belt 39, a flat belt main pulley 40, and a transmission flat belt motor 41. The circular belt driven pulley 33 and the circular belt driving pulley 36 are located on both sides of the support profile 35, tightening the transmission circular belt 34. When the transmission circular belt motor 37, connected to the circular belt driving pulley 36, rotates, it drives the transmission circular belt 34 to move, transmitting the blood collection tubes to the rear flat belt section. Similarly, the flat belt driven pulley 38, the transmission flat belt 39, the flat belt main pulley 40, and the transmission flat belt motor 41 form a flat belt module in the same manner, transmitting the blood collection tubes to the push rod of the push rod unit 43. The transmission unit 44 adopts a segmented transmission structure. When too many blood collection tubes accumulate inside the transmission unit 44, the circular belt transmission module and the feeding unit 43 are controlled to stop moving until all blood collection tubes in the flat belt module are processed, thereby preventing tube blockage inside the transmission unit 44 and at the connection with the feeding unit 43.

[0030] In summary, the dual-compartment feeding and conveying mechanism of the automatic vacuum blood collection tube sorting device provided by this utility model does not require manual intervention during operation. Compared with traditional sorting and feeding and conveying mechanisms, it can sort blood collection tubes with higher priority according to batch, and has high market application and promotion value.
