Description

Technical Field

[0001] This invention relates to the field of medical equipment technology, specifically to an automatic packaging and labeling device for vacuum blood collection tubes. Background Technology

[0002] Currently, hospital staff need to confirm the doctor's orders before collecting blood to prepare the corresponding number of blood collection tubes. Then, they attach labels to the surface of the blood collection tubes. Finally, multiple blood collection tubes for the same patient are bundled together with rubber bands or placed in a collection bag before blood is collected from patients in different wards.

[0003] Using rubber bands for binding and labeling requires matching the doctor's order to dispense the tubes, increasing the workload of medical staff. The whole process takes about two hours and is prone to operational errors and lacks traceability, often resulting in missed or extra tubes. If bags are used, an external label is needed to identify patient information, and while transparent boxes are generally standardized, different patients require different numbers of blood collection tubes. When the number is small, the space inside the box cannot be used effectively, and the blood collection tubes are easily bumped and scratched by the tubes inside the box. Summary of the Invention

[0004] This invention provides an automatic packaging and labeling device for vacuum blood collection tubes, which can automatically dispense test tubes according to information from the hospital system, affix patient information labels, and cut out test tubes with the same patient information labels along with the material tape for use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

It is used to clamp the test tubes that are picked up and transferred from the test tube placement mechanism by the tube-retrieving mechanism and to drive the test tubes to roll. The label printer is located to the side of the labeling mechanism. It is used to print patient information labels according to hospital system instructions and cooperates with the labeling mechanism to affix the printed labels to the test tubes.

[0009] The conveyor belt mechanism is located to the side of the test tube placement mechanism and is used to place and release the rolled conveyor belt. The conveyor belt conveyor mechanism is located to the tail side of the conveyor belt mechanism and is used to drive the conveyor belt to move. The conveyor belt is mounted on the conveyor belt mechanism and can extend to the conveyor belt conveyor mechanism. Driven by the conveyor belt conveyor mechanism, it can continuously move forward to load labeled test tubes.

[0010] The cutting mechanism is located on the side of the conveyor belt and is used to cut the conveyor belt, cutting out the test tubes with the same label information along with the conveyor belt. The unloading bin is located on the tail side of the conveyor belt and is used to receive the cut test tubes and guide them to a designated position.

[0011] Preferably, the test tube placement mechanism includes a placement rack and a placement slot. The placement rack is mounted on a base plate, and the placement slot is mounted on the placement rack for storing test tubes to be used.

The gripper motor is disposed on the vertical moving plate, and the gripper assembly is disposed on the output end of the gripper motor to clamp the test tube and transfer it to the labeling mechanism and to load the labeled test tubes onto the material belt.

[0015] Preferably, the labeling mechanism includes a mounting base, a rotary motor, a rotating component, a pressure shaft, a rolling motor, and a roller.

The rotating component is axially rotatable and mounted on the mounting base and connected to the rotary motor. The pressure shaft is mounted on the rotating component. The rotary motor drives the rotating component, causing the pressure shaft and the roller to cooperate to clamp the test tube transferred by the gripper assembly and drive the test tube to roll, thus affixing the label printed by the label printer onto the test tube.

[0016] Preferably, the material belt includes a belt body, tube loading holes, a flange, and identification holes. The belt body is rolled up on the material belt turntable mechanism and extends to the material belt conveying mechanism at one end. The tube loading holes are evenly distributed on the belt body for loading test tubes with labels attached. The flange is located around the tube loading holes to stabilize the loaded test tubes. The identification holes are evenly distributed on the belt body and located between two tube loading holes for cooperating with the material belt conveying mechanism to drive the belt body to move.

[0017] Preferably, the material belt turntable mechanism includes a turntable frame, a turntable, and an adjusting component. The turntable is mounted on a base plate and is located on the turntable frame for placing and releasing the rolled-up material belt.

The support is mounted on a base plate, and the cutting guide rail and cutting motor are both mounted on the support. The cutting lifting plate is mounted on the cutting guide rail and can move along the cutting guide rail. The cutting rack is mounted on the cutting lifting plate and meshes with the output end of the cutting motor. The cutter assembly is located on the top of the cutting lifting plate and extends above the feeding guide rail. The cutting motor drives the cutting lifting plate to move up and down, thereby causing the cutter assembly to cut the tape containing test tubes with the same patient label information on the feeding guide rail.

[0020] Compared with existing technologies, the advantages of this invention are that it can fully automate the preparation, printing, and labeling of blood collection tubes based on information from the hospital system, eliminating the need for medical staff to prepare each blood collection tube individually. The blood collection tubes are arranged in an orderly manner on a conveyor belt, and labels can be applied to the same patient's blood collection tubes in an orderly fashion. Then, through the cooperation of the identification hole and the conveyor belt mechanism, the location of the blood collection tubes for the same patient can be accurately identified. A cutting mechanism then cuts the blood collection tubes with the same information together. Medical staff only need to pick up the cut blood collection tubes to draw blood from the corresponding patients, improving the efficiency of medical staff and greatly reducing the time required for preparing blood collection tubes, allowing them more time to do other tasks.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0033] Please see Figure 1 and Figure 9 As shown, an automatic packaging and labeling device for vacuum blood collection tubes includes a base plate 1. On the base plate 1 are a test tube placement mechanism 2, a material belt turntable mechanism 6, a label printer 5, a material belt conveying mechanism 7, a labeling mechanism 4, a cutting mechanism 9, a tube picking mechanism 3, a material belt 8, and a feeding bin 10. The test tube placement mechanism 2 is located on the base plate 1 and is used to store test tubes to be used. The tube picking mechanism 3 is located on the tail side of the test tube placement mechanism 2 and is used to pick up the test tubes to be used on the test tube placement mechanism 2 and transfer them to the labeling mechanism 4, and to pick up the labeled test tubes and transfer them to the material belt 8.

[0034] The labeling mechanism 4 is located below the tube-taking mechanism 3. It is used to clamp the test tubes that the tube-taking mechanism 3 picks up and transfers from the test tube placement mechanism 2 and drive the test tubes to roll. The label printer 5 is located on the side of the labeling mechanism 4. It is used to print patient information labels according to the hospital system instructions and cooperate with the labeling mechanism 4 to affix the printed labels to the test tubes.

[0035] The conveyor belt mechanism 6 is located on the side of the test tube placement mechanism 2 and is used to place and release the rolled conveyor belt 8. The conveyor belt mechanism 7 is located on the tail side of the conveyor belt mechanism 6 and is used to drive the conveyor belt 8 to move. The conveyor belt 8 is located on the conveyor belt mechanism 6 and can extend to the conveyor belt mechanism 7. Driven by the conveyor belt mechanism 7, it can continuously move forward to load the labeled test tubes.

[0036] The cutting mechanism 9 is located on the side of the conveyor belt 7 and is used to cut the conveyor belt. It cuts out the test tubes with the same label information on the conveyor belt 8 together with the conveyor belt 8. The unloading bin 10 is located on the tail side of the conveyor belt 7 and is used to receive the cut test tubes and guide them to the designated position.

[0037] The specific working process is as follows: First, the test tubes are placed on the test tube placement mechanism 2 for storage and preparation. Then, according to the instructions from the hospital system, the tube retrieval mechanism 3 moves to the test tube placement mechanism 2, picks up the test tubes, and transfers them to the labeling mechanism 4. Next, the label printer 5 prints patient information labels based on the information provided by the hospital system. The labeling mechanism 4 then applies the printed labels to the test tubes using a rolling motion. Finally, the tube retrieval mechanism 3 picks up the labeled test tubes and loads them onto the conveyor belt 8. The conveyor belt 8 is placed in a roll on the conveyor belt turntable mechanism 6, with one end extending to the conveyor belt conveyor mechanism 7. The drive belt 8 moves forward a short distance after each test tube is loaded, allowing the next test tube to be loaded onto the belt. Once all the test tubes needed for the same patient are loaded onto the belt, the cutting mechanism 9 cuts off the test tubes along with the belt. The cut test tubes fall into the discharge bin 10. Medical staff can then simply remove the cut test tubes connected by the belt 8 and take them to the patient with the same label information for blood collection. After blood collection, the tubes can be loaded back into the original belt 8 and sent for testing. The entire process does not require medical staff to spend a lot of time preparing blood collection tubes.

[0038] Please see Figure 2 As shown, the test tube placement mechanism 2 includes a placement rack 21 and a placement groove 22. The placement rack 21 is mounted on the base plate 1, and the placement groove 22 is mounted on the placement rack 21 for storing test tubes to be used. The placement rack 21 has a certain slope, allowing the test tubes to slide along the placement groove 22 to a designated position. The width of the placement groove 22 is greater than the diameter of the test tube body but smaller than the diameter of the test tube cap, ensuring that the test tubes are stored in a uniform posture within the placement groove 22 for use.

[0039] Please see Figure 3 As shown, the tube-retrieving mechanism 3 includes a crossbeam frame 31, a transverse guide rail assembly 32, a transverse motor 34, a transverse rack 33, a transverse plate 35, and a tube-clamping mechanism 36. The crossbeam frame 31 is mounted on the base plate 1. The transverse guide rail assembly 32 and the transverse rack 33 are mounted parallel to each other on the crossbeam frame 31. The transverse plate 35 is mounted on the transverse guide rail assembly 32 and can move along the transverse guide rail assembly 32. The transverse motor 34 is mounted on the transverse plate 35 and its output end meshes with the transverse rack 33 to drive the transverse plate 35 to move along the transverse guide rail assembly 32. The tube-clamping mechanism 36 is mounted on the transverse plate 35 and is used to clamp the test tubes to be used in the placement slot 22.

[0040] The tube clamping mechanism 36 includes a vertical guide rail assembly 361, a vertical moving plate 362, a vertical moving rack 364, a vertical moving motor 363, a gripper motor 365, and a gripper assembly 366. The vertical guide rail assembly 361 and the vertical moving rack 364 are parallel to each other and are both arranged on the vertical moving plate 362. The vertical moving plate 362 is slidably connected to the horizontal moving plate 35 through the vertical guide rail assembly 361. The vertical moving motor 363 is arranged on the horizontal moving plate 35 and its output end is engaged with the vertical moving rack 364 to drive the vertical moving plate 362 to move. The gripper motor 365 is arranged on the vertical moving plate 362, and the gripper assembly 366 is arranged on the output end of the gripper motor 365 to clamp the test tube and transfer it to the labeling mechanism 4 and to load the labeled test tubes onto the material belt 8.

[0041] During operation, the first step is tube removal. The horizontal movement motor 34 drives the horizontal movement plate 35 to move along the horizontal guide rail assembly 32, thereby moving the tube clamping mechanism 36 above the test tube placement mechanism 2. Then, the vertical movement motor 363 drives the gripper assembly 366 to descend and clamp the test tube on the test tube placement mechanism 2 before rising back to its original position. Then, the horizontal movement motor 34 operates again, moving the tube clamping mechanism 36 above the labeling mechanism 4. The vertical movement motor 363 also drives the gripper assembly 366 to descend and place the test tube on the labeling mechanism 4. Then, the gripper assembly 366 rises to await the next instruction. The second step is tube loading. After the test tube on the labeling mechanism 4 is labeled, the vertical movement motor 363 drives the gripper assembly 366 to descend and clamp the labeled test tube before rising. The horizontal movement motor 34 drives the tube clamping mechanism 36 above the material conveyor mechanism 7, and the vertical movement motor 363 drives the gripper assembly 366 to load the labeled test tube into the material belt 8 on the material conveyor mechanism 7. This process is repeated.

[0042] Please see Figure 4As shown, the labeling mechanism 4 includes a mounting base 41, a rotary motor 42, a rotating component 43, a pressure shaft 44, a rolling motor 45, and a roller 46. The mounting base 41 is mounted on the base plate 1. The rotary motor 42 and the rolling motor 45 are both mounted on the mounting base 41. The roller 46 is mounted on the mounting base 41 and connected to the rolling motor 45. The rolling motor 45 drives the roller 46 to rotate. The rotating component 43 is axially rotatable on the mounting base 41 and connected to the rotary motor 42. The pressure shaft 44 is mounted on the rotating component 43. The rotary motor 42 drives the rotating component 43, so that the pressure shaft 44 and the roller 46 cooperate to hold the test tube transferred by the gripper assembly 366 and drive the test tube to roll, thus affixing the label printed by the label printer 5 onto the test tube. During operation, according to the system's instructions, after the tube-grabbing mechanism 3 picks up the test tube, the rotary motor 42 drives the rotating component 43 and the pressure shaft 44 to rotate at a certain angle. When the tube-grabbing mechanism 3 places the test tube at the roller 46, the rotary motor 42 drives the rotating component 43 and the pressure shaft 44 to rotate again to fix the test tube on the roller 46. The rolling motor 45 drives the roller 46 to rotate. After the label printer 5 prints the label, the label moves to abut against the test tube or is delivered to the test tube by the label printer 5 moving on the base plate 1. After the roller 46 and the pressure shaft 44 roll together, the label is attached to the body of the test tube. After it is attached, the roller 46 stops rotating, and the tube-grabbing mechanism 3 picks up the label test tube. After the tube-grabbing mechanism 3 picks up the test tube, the rotary motor 42 drives the rotating component 43 to rotate so that the tube-grabbing mechanism 3 can pick up the label test tube and transfer it to the conveyor belt 8.

[0043] Please see Figure 7 As shown, the material belt 8 includes a belt body 81, tube loading holes 82, flanges 83, and identification holes 84. The belt body 81 is rolled up on the material belt turntable mechanism 6 and extends to the material belt conveying mechanism 7 at one end. The tube loading holes 82 are evenly distributed on the belt body 81 and are used to load test tubes with labels attached. The flanges 83 are located around the tube loading holes 82 and are used to stabilize the loaded test tubes. The identification holes 84 are evenly distributed on the belt body 81 and are located between two tube loading holes 82. They are used to cooperate with the material belt conveying mechanism 7 to drive the belt body 81 to move.

[0044] Please see Figure 5 As shown, the material belt turntable mechanism 6 includes a turntable frame 61, a turntable 62, and an adjusting member 63. The turntable frame 61 is mounted on the base plate 1, and the turntable 62 is mounted on the turntable frame 61 for placing and releasing the rolled belt 81. The adjusting member 63 is mounted on one end of the turntable frame 61 for adjusting the tension of the belt 81 that extends to the material belt conveying mechanism 7.

[0045] Please see Figure 6As shown, the material conveying mechanism 7 includes a fixed base 71, a conveying motor 72, a rotating shaft 73, a ratchet 74, a feeding guide rail 75, a pressing assembly 76, and a height limiting component 77. The fixed base 71 and the conveying motor 72 are both mounted on the base plate 1. The rotating shaft 73 is mounted on the fixed base 71 and connected to the conveying motor 72. The ratchet 74 is sleeved on the rotating shaft 73 and corresponds to the identification hole 84, used to drive the belt body 81 to move. The feeding guide rail 75 is horizontally mounted on the fixed base 71, used to guide the belt body 81 forward to move below the cutting mechanism 9. The pressing assembly 76 is mounted on the top of the fixed base 71, used to press down the belt body 81 to stabilize the engagement between the ratchet 74 and the identification hole 84. The height limiting component 77 is mounted on the feeding guide rail 75, used to prevent the belt body 81 from arching or misaligning during movement.

[0046] During operation, the conveyor belt 8 extends from the conveyor belt turntable mechanism 6 to the conveyor belt guide rail 75. Because the conveyor belt 8 has an identification hole 84, which can cooperate with the ratchet 74, when the conveyor motor 72 drives the ratchet 74, the conveyor belt 8 can be pushed forward through the cooperation of the identification hole 84 and the ratchet 74. Whenever the tube picking mechanism 3 loads a labeled test tube onto the conveyor belt 8, the ratchet 74 pushes the conveyor belt 8 forward by one test tube position to facilitate subsequent loading of test tubes. For example, according to the hospital system, this patient needs three test tubes. The tube picking mechanism 3 delivers the required test tubes one by one to be labeled and loads the labeled test tubes one by one onto the conveyor belt 8. Each time a test tube is loaded, the ratchet 74 pushes the conveyor belt 8 forward by one position. When all three labeled test tubes are loaded, the cutting mechanism 9 cuts the test tubes with the same patient information together with the conveyor belt 8.

[0047] Please see Figure 8 As shown, the cutting mechanism 9 includes a support 91, a cutting motor 92, a cutting guide rail 93, a cutting lifting plate 94, a cutting rack 95, and a cutter assembly 96. The support 91 is mounted on the base plate 1. The cutting guide rail 93 and the cutting motor 92 are both mounted on the support 91. The cutting lifting plate 94 is mounted on the cutting guide rail 93 and can move along the cutting guide rail 93. The cutting rack 95 is mounted on the cutting lifting plate 94 and meshes with the output end of the cutting motor 92. The cutter assembly 96 is mounted on the top of the cutting lifting plate 94 and extends above the feeding guide rail 75. The cutting motor 92 drives the cutting lifting plate 94 to move up and down, thereby driving the cutter assembly 96 to cut the material tape 8 containing test tubes with the same patient label information on the feeding guide rail 75. According to the instructions of the hospital system, when cutting is required, the cutting motor 92 drives the cutter head assembly 96 to descend through the cutting rack 95, cutting the material belt 8 containing the labeled test tubes on the material belt conveyor 7. After cutting, the cutter head assembly 96 rises back to its original position, waiting for the next cutting instruction, and so on for repeated operation.

[0048] This invention can automatically prepare blood collection tubes, print and affix labels based on information from the hospital system, eliminating the need for medical staff to prepare each tube individually. The tubes are arranged in an orderly manner on a conveyor belt, and labels are affixed to the tubes needed for the same patient. Through the cooperation of an identification hole and the conveyor belt mechanism, the location of the tubes for the same patient is accurately identified. A cutting mechanism then groups tubes with the same information together and cuts them out. Medical staff simply pick up the cut tubes and draw blood from the corresponding patients, improving their work efficiency and significantly reducing the time spent preparing blood collection tubes, allowing them more time for other tasks.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
