Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a test tube labeling machine. Background Art

[0002] Blood sample testing in hospitals is an important means for doctors to diagnose diseases and an essential item for ordinary people's routine physical examinations. To facilitate differentiation, different blood test items usually use different styles of blood collection tubes. When testing a large number of blood samples, important information is usually printed on a label in the form of a barcode or relevant text information, and the label is pasted on the corresponding blood collection tube.

[0003] Traditional labeling operations are completed through the division of labor of different medical staff. That is, the doctor first issues a doctor's order for the specimen to be collected, and the label is automatically generated by a computer. Then the printer automatically prints a label containing important information such as the ward area, bed number, inpatient number, name, gender, name of the required sample, barcode, and type of the required test tube. After the nurse checks the doctor's order, the nurse carries the label to find the corresponding specimen test tube. After finding the specimen test tube, the nurse manually pastes the specimen label. Finally, the clinical nurse uses a PDA scanner to scan the barcode for specimen collection and submission. Due to the large number of patients and the variety of blood collection tubes, the workload of medical staff is relatively large. In addition, manual labeling operations are prone to errors, which may lead to medical accidents. To solve the above problems, R & D personnel have developed an automatic labeling machine. Its working principle is as follows: Three rubber rollers are used to clamp the test tube. One of the three rubber rollers is the driving roller. When the driving roller rotates, it can drive the test tube to rotate. During the rotation of the test tube, the label printing and peeling device peels the label from the base tape and makes its end penetrate between the test tube and the rubber roller, and the rotating test tube can then perform the labeling work.

[0004] However, it is found in the use process that the above traditional labeling machine requires manual and timely replenishment of test tubes during use. Therefore, additional medical staff are required for tube replenishment operations, which not only occupies additional human resources but also reduces the labeling efficiency of test tubes. In addition, the functions of traditional labeling machines are relatively single. They can only peel the label from the base tape and paste it on the test tube. In actual sampling processes, there will be situations where labels containing certain specific information need to be pasted at specific positions on the test tube. The above traditional labeling machines cannot meet such labeling requirements and need to be completed through traditional labeling operations (i.e., through the division of labor of different medical staff). They have a single function and poor applicability. Therefore, it is urgent to design a test tube labeling machine to solve the above problems. Summary of the Invention

[0005] The present invention provides a test tube labeling machine with a reasonable structural design to solve the technical problems existing in the known art. The present invention can store a large number of various test tubes, and realize the automatic falling, conveying, labeling and discharging operations of the test tubes, with high automation and high working efficiency. In addition, the present invention can provide specific specimen test tubes and single label papers containing certain specific information, which is convenient for medical staff to manually paste the labels at specific positions of the test tubes, saving the process of medical staff searching for specimen test tubes, and has strong applicability.

[0006] The technical solution adopted by the present invention to solve the technical problems existing in the known art is: a test tube labeling machine includes a machine shell structure, and a plurality of groups of tube storage cavities are arranged in parallel at the upper part of the inner cavity of the machine shell structure for storing test tubes to be used; it also includes a tube dropping device connected to each tube storage cavity for conveying test tubes; it also includes an out-tube funnel structure installed at the discharge port of the tube dropping device for arranging the test tubes conveyed by the tube dropping device in a single layer; it also includes a test tube position adjusting device for adjusting the position of the test tube at the bottom layer in the inner cavity of the out-tube funnel structure; it also includes a tube blocking device for controlling the opening and closing state of the discharge port of the out-tube funnel structure; a driving pinch roller device is arranged beside the discharge port of the out-tube funnel structure, and a driven pinch roller structure for receiving the test tubes dropped from the out-tube funnel structure is arranged below the tube blocking device, a sliding material guiding plate is arranged below the driven pinch roller structure, and a material taking box inserted into the inner cavity of the machine shell structure is arranged below the discharge end of the sliding material guiding plate; it also includes a roller moving device for driving the driven pinch roller structure to move between the discharge end of the out-tube funnel structure, the feeding end of the sliding material guiding plate and the driving pinch roller device; a tube pushing device for pushing the test tubes on the driven pinch roller structure is installed on the roller moving device; an out-label assembly located beside the material taking box is arranged below the sliding material guiding plate for supplying single labels adhered with a substrate; it also includes a label supply device arranged above the sliding material guiding plate, and the label supply device and the driven pinch roller structure are respectively located on both sides of the driving pinch roller device.

[0007] The advantages and positive effects of the present invention are as follows: The present invention provides a test tube labeling machine. By setting a tube storage cavity, a large number of test tubes of different types can be classified and stored. By setting a tube dropping device, the test tubes to be labeled can be grabbed according to the types of sample test tubes, and it is ensured that the test tubes drop downward in the correct posture. By the combined action of the tube outlet funnel structure and the tube blocking device, the test tubes dropped from the tube dropping device can be received, and the dropped test tubes are arranged in a single layer. By setting a test tube position adjustment device, the position of the test tube at the bottom layer in the tube outlet funnel structure can be adjusted according to the pasting position of the label. By setting a driven pinch roller structure and a roller moving device, the test tube at the bottom layer in the tube outlet funnel structure can be automatically received. Cooperating with the active pinch roller device and the label supply device, the labeling operation of the test tube can be realized, and the test tube can be transferred to other places after the labeling operation is completed. By setting a tube pushing device, the test tubes that have completed the labeling operation can be pushed out to realize the automatic discharging operation of the test tubes. Through the above settings, the operations of tube dropping, tube clamping, label peeling, labeling, and tube discharging can be carried out in a cycle, without the need to additionally equip medical staff for tube replenishment operations, reducing the labor cost and improving the working efficiency of the labeling machine. By setting a label output assembly, the cutting and printing operations of the labels can be realized, which is convenient for the operator to take out the labels and the sample test tubes to be labeled at the same time, saving the process of the operator searching for the sample test tubes, simplifying the process of manual labeling operation, and improving the applicability of the test tube labeling machine.

[0025] To further understand the content, features and effects of the present invention, the following embodiments are given for detailed description as follows:

[0026] Please refer to Figure 1, the test tube labeling machine of the present invention includes a housing structure 19. In the upper part of the inner cavity of the housing structure 19, multiple groups of tube storage cavities 18 are arranged side by side; for storing test tubes 100 to be used. During the actual working process, different types of test tubes 100 are horizontally stacked and placed in different tube storage cavities 18. In addition, this embodiment further includes a tube dropping device 17 connected to each tube storage cavity 18 for conveying the test tubes 100. This embodiment also includes a tube outlet funnel structure 14 installed at the outlet of the tube dropping device 17 for arranging the test tubes 100 conveyed by the tube dropping device 17 in a single layer.

[0027] Among them, the tube dropping device 17 includes a tube storage bin structure. Multiple groups of tube storage cavities 18 are distributed along the length direction of the tube storage bin structure; at the lower end of the tube storage bin, a tube dropping guiding structure connected to the tube outlet funnel structure 14 is installed; it also includes a tube picking component arranged between the outlet of the tube storage bin structure and the tube dropping guiding structure.

[0028] Further refer to Figure 2 and Figure 3 , in this embodiment, the tube storage bin structure includes a tube storage front mounting plate 17-1 and a tube storage rear mounting plate 17-7 arranged oppositely. Between the tube storage front mounting plate 17-1 and the tube storage rear mounting plate 17-7, multiple groups of tube storage partition plates 17-9 are fixedly connected in parallel along their length directions. Each tube storage cavity 18 is composed of the tube storage front mounting plate 17-1, the tube storage rear mounting plate 17-7, and two adjacent tube storage partition plates 17-9. Among them, the height of the tube storage front mounting plate 17-1 is lower than the height of the tube storage rear mounting plate 17-7, and the top of the tube storage rear mounting plate 17-7 is flush with the top of each tube storage partition plate 17-9; through this setting, it is convenient to place a large number of test tubes 100 into each tube storage cavity 18 at one time;

[0029] In addition, the tube dropping guiding structure includes a first sliding tube bottom plate 17-12 and a second sliding tube bottom plate 17-13 connected between the upper end of the tube outlet funnel structure 14 and two groups of tube storage partition plates 17-9 located at the end. Both the first sliding tube bottom plate 17-12 and the second sliding tube bottom plate 17-13 are inclined downward and gradually approach the tube outlet funnel structure 14. For the convenience of installation and subsequent disassembly and maintenance, the upper end of the first sliding tube bottom plate 17-12 is hinged to the tube storage partition plate 17-9 at one end through a hinge, and the upper end of the second sliding tube bottom plate 17-13 is hinged to the tube storage partition plate 17-9 at the other end through a hinge. The lower ends of the first sliding tube bottom plate 17-12 and the second sliding tube bottom plate 17-13 are detachably connected to the upper end of the tube outlet funnel structure 14 through bolts and lock nuts.

[0030] The dropping tube device 17 further includes a front light-transmitting plate 17-2 and a rear light-transmitting plate 17-3 which are correspondingly arranged on both sides of the first sliding tube bottom plate 17-12 and the second sliding tube bottom plate 17-13. By providing the front light-transmitting plate 17-2 and the rear light-transmitting plate 17-3, it is convenient to observe the feeding condition of the test tube 100. Among them, the top of the front light-transmitting plate 17-2 is butted against the bottom of the front storage tube mounting plate 17-1, and the top of the rear light-transmitting plate 17-3 is butted against the bottom of the rear storage tube mounting plate 17-7.

[0031] As Figure 2 and Figure 3 As shown, in this embodiment, the tube taking assembly includes discharging dial wheels 17-10 which are rotatably connected to the lower ports of the respective storage tube cavities 18. A plurality of groups of test tube accommodating grooves 17-11 which are circumferentially and equally angularly distributed are formed on the outer peripheral surface of the discharging dial wheel 17-10 for grasping the test tube 100. In this embodiment, each discharging dial wheel 17-10 is provided with four groups of test tube accommodating grooves 17-11.

[0032] To facilitate the precise grasping of the test tube 100, the test tube accommodating groove 17-11 includes a long section and a short section which extend along the axial direction of the discharging dial wheel 17-10. The inner diameter of the long section is adapted to the outer diameter of the tube body of the test tube 100, and the inner diameter of the short section is adapted to the outer diameter of the tube cap of the test tube 100. During the actual working process, when the discharging dial wheel 17-10 rotates, the test tube 100 at the bottom layer of the storage tube cavity 18 falls into the test tube accommodating groove 17-11 and drops onto the first sliding tube bottom plate 17-12 or the second sliding tube bottom plate 17-13 along with the rotation of the discharging dial wheel 17-10. Since both the first sliding tube bottom plate 17-12 and the second sliding tube bottom plate 17-13 are inclined, the test tube 100 dropped onto the first sliding tube bottom plate 17-12 and / or the second sliding tube bottom plate 17-13 will roll downward. In order to ensure that the test tube 100 dropped onto the first sliding tube bottom plate 17-12 and / or the second sliding tube bottom plate 17-13 can drop into the tube discharging flat tube 14-1 in the correct posture and prevent the test tube 100 from sliding in the wrong posture and blocking the upper feeding port of the tube discharging flat tube 14-1, the front side edges in the length direction of the first sliding tube bottom plate 17-12 and the second sliding tube bottom plate 17-13 are both stepped, so as to ensure that when the test tube 100 drops onto the sliding tube bottom plate, the outer peripheral wall of the tube body of the test tube 100 rolls in contact with the high-order table surface of the stepped structure, and the port edge of the tube cap of the test tube 100 contacts the shoulder of the stepped structure, so as to prevent the test tube 100 from tilting during the downward rolling process.

[0033] As Figure 2As shown, the pipe taking assembly also includes a plurality of groups of dial motors 17-4 installed on the rear mounting plate 17-7 of the pipe storage, which are respectively connected to each discharge dial 17-10 in a one-to-one manner; a code disk 17-5 is connected to the output shaft of each dial motor 17-4, and also includes a code disk sensor 17-6 which is respectively matched with each code disk 17-5 in a one-to-one manner. By setting the code disk 17-5 and the code disk sensor 17-6, the discharge dial 17-10 can be controlled to rotate a quarter of a turn at a time.

[0034] In addition, detection slots 17-8 corresponding to and connected to each tube storage cavity 18 are provided on the tube storage rear mounting plate 17-7, and a PCB board is installed on the tube storage rear mounting plate 17-7. Multiple sets of sensors are installed on the PCB board, and each sensor is respectively and correspondingly arranged in each detection slot 17-8. Through the above-mentioned arrangement, the situation in each tube storage cavity 18 can be detected in real time. When the top layer of the test tubes 100 stacked in the tube storage cavity 18 is lower than the detection slot 17-8, the corresponding sensor transmits the detected information to the electric control console installed on the casing structure 19 of the labeling machine, and after processing and judgment by the electric control console, the operator is prompted to perform the operation of replenishing the test tube 100 in the tube storage cavity 18.

[0035] like Figure 3 and Figure 4 As shown, in this embodiment, the tube outlet funnel structure 14 includes a tube outlet flat cylinder 14-1 with open upper and lower ends, wherein the tube outlet flat cylinder 14-1 is a rectangular structure, and its width is slightly larger than the diameter of the test tube 100, so as to achieve the purpose of arranging multiple test tubes 100 in a single layer and falling into the tube outlet flat cylinder 14-1.

[0036] To facilitate installation and serve as a guide, two groups of outwardly folded arc-shaped guide plates 14-5 are integrally connected to the upper end of the guide cylinder 14-4, and each arc-shaped guide plate 14-5 is provided with an arc-shaped surface that serves a guiding role; in addition, each arc-shaped guide plate 14-5 is provided with a plurality of groups of strip holes, and the pipe outlet flat cylinder 14-1 is detachably connected to the first slide tube bottom plate 17-12 and the second slide tube bottom plate 17-13 by bolts and locking nuts passed through the above-mentioned strip holes.

[0037] A pipe connection slot 14-2 is provided at the lower end of the side wall in the length direction of the pipe outlet flat cylinder 14-1, a sweeping hole 14-3 is provided above the pipe connection slot 14-2, and a sweeping sensor is provided in cooperation with the sweeping hole 14-3. The pipe outlet funnel structure 14 also includes a through hole provided on the side wall in the width direction of the guide cylinder portion 14-4 and located above the pipe connection slot 14-2, and the guide cylinder portion 14-4 is fixedly connected to the through hole.

[0038] like Figure 1As shown, in order to control the opening and closing state of the discharge port of the discharge funnel structure 14, this embodiment also includes a pipe blocking device 16. Figure 4 In this embodiment, the pipe intercepting device 16 includes a right-angle mounting seat fixedly connected to the casing structure 19, a pipe intercepting bearing seat 16-2 is fixedly connected to the above-mentioned right-angle mounting seat, and a transversely arranged pipe intercepting guide rod 16-5 is slidably connected to the pipe intercepting bearing seat 16-2 through a linear bearing, wherein two groups of pipe intercepting guide rods 16-5 are provided. A pipe intercepting plate 16-1 that can cover the discharge port of the pipe discharge funnel structure 14 is connected to one end of the pipe intercepting guide rod 16-5. In this embodiment, the pipe intercepting plate 16-1 is an L-shaped structure. A guide rod connecting plate 16-3 is installed at the other end of the pipe intercepting guide rod 16-5, and also includes a pipe intercepting driving member 16-4 installed on the right-angle mounting seat for driving the guide rod connecting plate 16-3 to move along the axial direction of the pipe intercepting guide rod 16-5. The pipe intercepting driving member 16-4 is a linear driving member. In this embodiment, the pipe intercepting driving member 16-4 adopts an electromagnetic valve push rod. In addition, the above-mentioned edge sweeping sensor is installed on the pipe blocking plate 16-1.

[0039] In the actual working process, the start of the pipe blocking drive member 16-4 can drive the guide rod connecting plate 16-3 to move, and then drive the pipe blocking plate 16-1 to move axially along the pipe blocking guide rod 16-5, thereby ensuring that when the pipe blocking plate 16-1 is inserted into the connecting pipe groove 14-2, the purpose of closing the discharge port of the pipe outlet flat cylinder 14-1 is achieved, preventing the test tube 100 from falling out of the discharge port of the pipe outlet flat cylinder 14-1; when the pipe blocking plate 16-1 moves outward to the outside of the connecting pipe groove 14-2, the discharge port of the pipe outlet flat cylinder 14-1 is opened, and the test tube can fall out of the discharge port of the pipe outlet flat cylinder 14-1.

[0040] like Figure 1 As shown, in order to adjust the lateral position of the test tube 100 located at the bottom of the inner cavity of the tube outlet funnel structure 14 so that the label can be pasted at a height position that meets the requirements, this embodiment also includes a test tube positioning device 15. For further information, see Figure 4 In this embodiment, the test tube positioning device 15 includes a positioning driving member 15-1, which is a linear driving member. In this embodiment, the positioning driving member 15-1 adopts a solenoid valve push rod. A positioning connecting arm 15-3 is installed at the extended end of the positioning driving member 15-1, and a positioning push rod 15-2 slidably penetrated in the guide cylinder 14-4 is installed on the positioning connecting arm 15-3, which is used to push the test tube 100 located in the tube outlet flat cylinder 14-1 and at the bottom layer, so that the top of the tube cap of the test tube 100 is in close contact with the inner wall of the tube outlet flat cylinder 14-1.

[0041] In order to achieve the purpose of receiving and clamping the test tube 100 and driving the test tube 100 to rotate at the same time, this embodiment further includes an active pinch roller device 13 arranged beside the discharge port of the tube outlet funnel structure 14, and also includes a driven pinch roller structure 10 arranged below the tube blocking device 16 for receiving the test tube 100 dropped from the tube outlet funnel structure 14. A slide material guiding plate 2 is arranged below the driven pinch roller structure 10, and a material taking box 1 inserted into the inner cavity of the machine shell structure 19 is arranged below the discharge end of the slide material guiding plate 2. This embodiment further includes a roller moving device 11, and the roller moving device 11 can drive the driven pinch roller structure 10 to move between the discharge end of the tube outlet funnel structure 14, the feed end of the slide material guiding plate 2 and the active pinch roller device 13.

[0042] Further referring to Figure 5 and Figure 6 In this embodiment, the active pinch roller device 13 includes a pinch roller seat 13-2 installed on the machine shell structure 19. A horizontally arranged active pinch roller 13-1 is rotatably connected to the pinch roller seat 13-2. It also includes a pinch roller motor 13-3 installed on the machine shell structure 19 for driving the active pinch roller 13-1 to rotate.

[0043] In addition, the driven pinch roller structure 10 includes two sets of relatively arranged L-shaped mounting parts 10-1 fixedly connected to the moving end of the roller moving device 11. A first driven pinch roller 10-2 and a second pinch roller 10-3 are rotatably connected between the two sets of L-shaped mounting parts 10-1. The first driven pinch roller 10-2 and the second pinch roller 10-3 are respectively rotatably connected to the two end parts of the L-shaped mounting part 10-1. The longitudinal position of the second pinch roller 10-3 is higher than the longitudinal position of the first driven pinch roller 10-2. In the horizontal direction, the first driven pinch roller 10-2 is located between the second pinch roller 10-3 and the active pinch roller 13-1. In order to detect whether the lateral position of the test tube 100 on the driven pinch roller structure 10 meets the labeling requirements, a sensor mounting bracket is installed on the moving end of the roller moving device 11, and a side scanning sensor is installed on the sensor mounting bracket. The above-mentioned side scanning sensor is linked with the test tube position adjusting device 15. When the side scanning sensor detects that the position of the test tube 100 between the first driven pinch roller 10-2 and the second pinch roller 10-3 does not meet the labeling requirements in the axial direction of the pinch roller, the position adjusting driving part 15-1 in the test tube position adjusting device 15 is started to drive the position adjusting push rod 15-2 to move, and then push the test tube 100 in the axial direction of the pinch roller, so that the test tube 100 moves to a position where the top of its tube cap is in tight contact with the inner wall of the tube outlet flat tube 14-1.

[0044] Such as Figure 5As shown in the figure, in this embodiment, the roller moving device 11 includes a moving general seat 11-3 fixedly connected to the housing structure 19. A horizontally arranged transverse movement guide rail 11-4 is fixedly connected to the moving general seat 11-3. A transverse movement mounting seat 11-5 is slidably connected to the transverse movement guide rail 11-4 through a slider. It further includes a transverse movement driving member 11-2 installed on the moving general seat 11-3 for driving the transverse movement mounting seat 11-5 to move along the transverse movement guide rail 11-4. The transverse movement driving member 11-2 is a linear driving member. In this embodiment, the transverse movement driving member 11-2 adopts a solenoid valve push rod.

[0045] The roller moving device 11 further includes a longitudinally arranged longitudinal movement guide rail 11-6 fixedly connected to the transverse movement mounting seat 11-5. A longitudinal movement mounting seat 11-1 is slidably connected to the longitudinal movement guide rail 11-6 through a slider. The driven pinch roller structure 10 is installed on the longitudinal movement mounting seat 11-1. It further includes a longitudinal movement driving member 11-7 installed on the transverse movement mounting seat 11-5 for driving the longitudinal movement mounting seat 11-1 to move along the longitudinal movement guide rail 11-6. The longitudinal movement driving member 11-7 is a linear driving member. Similarly, in this embodiment, the longitudinal movement driving member 11-7 adopts a solenoid valve push rod.

[0046] Under the action of the roller moving device 11, the driven pinch roller structure 10 can move longitudinally and transversely. When the driven pinch roller structure 10 moves longitudinally until the second pinch roller 10-3 penetrates into the pipe connection through slot 14-2, the driven pinch roller structure 10 is in the position waiting for pipe connection. At this time, the pipe blocking device 16 starts to open the discharge port of the pipe outlet flat tube 14-1 (that is, drives the pipe blocking plate member 16-1 to move to the outside of the pipe connection through slot 14-2). At this time, the test tube 100 at the bottom layer drops between the first driven pinch roller 10-2 and the second pinch roller 10-3 and is supported by the two, and then the driven pinch roller structure 10 completes the pipe connection operation. After the driven pinch roller structure 10 completes the pipe connection operation, the roller moving device 11 starts again, driving the driven pinch roller structure 10 to move towards the driving pinch roller device 13, so that the outer peripheral wall of the tube body of the test tube 100 is in tight contact with the outer peripheral surface of the driving pinch roller 13-1 in a tangential manner, thereby achieving the purpose of clamping the test tube by the combined action of the three roller members. At this time, the pinch roller motor 13-3 starts, which can drive the driving pinch roller 13-1 to rotate, and then drive the clamped test tube 100 to rotate.

[0047] To provide a label for peeling the baseband, this embodiment further includes a label supply device 9 disposed above the slide material guide plate 2. The label supply device 9 and the driven pinch roller structure 10 are respectively located on both sides of the driving pinch roller device 13. Among them, the label supply device 9 is a prior art and can be obtained by procurement. The label supply device 9 includes a plate member mounted on the housing structure 19, a winding shaft for inserting the second label roll 8 is mounted at the lower part of the plate member, and a label peeling member is further mounted at the upper part of the plate member. An end portion with an acute angle structure is provided at the upper part of the label peeling member; the above-mentioned acute angle end portion points to the tangency position of the driving pinch roller 13-1 and the test tube 100. It further includes a print head disposed above the label peeling member and a winding shaft disposed below the label peeling member, and further includes a motor for driving the winding shaft to rotate. When the motor starts, it can drive the winding shaft to rotate, thereby pulling the baseband of the second label roll 8. During the forward conveyance of the baseband, the label printed with important information adhered to the upper surface of the baseband moves forward synchronously. When the label passes through the acute angle end portion of the label peeling member, its end portion will break away from the baseband and move towards the space between the driving pinch roller 13-1 and the test tube 100. When the test tube 100 rotates, the label will be wrapped into the space between the driving pinch roller 13-1 and the test tube 100, so that the label is adhered to the outer peripheral wall of the test tube 100. After the test tube 100 completes the above-mentioned labeling operation, the roller moving device 11 starts, driving the test tube 100 to move away from the driving pinch roller device 13 to facilitate subsequent blanking operation.

[0048] As Figure 1 shown, in order to push out the test tube 100 that has completed the labeling operation and complete the blanking operation of the test tube, this embodiment further includes a tube pushing device 12 mounted on the roller moving device 11 for pushing the test tube 100 on the driven pinch roller structure 10. Further refer to Figure 5 and Figure 6, in this embodiment, the tube pushing device 12 includes a tube pushing bearing seat 12-3 fixedly connected to the longitudinal moving mounting seat 11-1. A laterally arranged tube pushing guide rod 12-4 is slidably connected to the tube pushing bearing seat 12-3 through a linear bearing. At one end of the tube pushing guide rod 12-4, a tube pushing and blanking member 12-5 for pushing the test tube 100 placed on the driven pinch roller structure 10 is installed. Among them, the tube pushing and blanking member 12-5 has a U-shaped structure, and the two legs of the U-shaped structure are respectively in clearance fit with the two L-shaped mounting members 10-1. Thus, when the tube pushing and blanking member 12-5 with a U-shaped structure moves horizontally towards the first driven pinch roller 10-2, it can push the test tube 100 supported by the first driven pinch roller 10-2 and the second pinch roller 10-3, so that the test tube 100 detaches from the driven pinch roller structure 10 and falls onto the material sliding guide plate 2. To drive the lateral movement of the tube pushing and blanking member 12-5, the tube pushing device 12 further includes a tube pushing moving connecting plate 12-2 installed at the other end of the tube pushing guide rod 12-4, and a tube pushing driving member 12-1 for driving the tube pushing moving connecting plate 12-2 to move along the axial direction of the tube pushing guide rod 12-4. The tube pushing driving member 12-1 is a linear driving member. Similarly, in this embodiment, the tube pushing driving member 12-1 uses a solenoid valve push rod.

[0049] To ensure that the test tube 100 pushed out by the tube pushing device 12 can accurately fall onto the material sliding guide plate 2, this embodiment further includes a blanking baffle 20 arranged between the label supply device 9 and the roller moving device 11. In this embodiment, the blanking baffle 20 is located at the rear side above the feed port of the material sliding guide plate 2. Thus, when the tube pushing device 12 starts to push out the test tube 100, the test tube 100 can fall onto the material sliding guide plate 2 under the limiting and blocking action of the blanking baffle 20 and fall onto the picking box 1 along the material sliding guide plate 2.

[0050] To achieve separate tube discharging and label discharging operations, this embodiment further includes a label discharging assembly arranged below the material sliding guide plate 2 and beside the picking box 1 for supplying single labels adhered with a substrate.

[0051] Among them, the label output assembly includes a lower printing mounting bracket 5 fixedly connected to the inner cavity bottom wall of the housing structure 19 and adjacent to the label taking box 1. A printer 3 and a label box 6 are installed on the lower printing mounting bracket 5. A label unwinding shaft for inserting a first label roll 7 is fixedly connected to the printing mounting bracket 5, and the first label roll 7 is placed in the label box 6. The label output assembly further includes a guiding and cutting device 4 arranged between the printer 3 and the label box 6. The guiding and cutting device 4 mainly includes a tape cutting mechanism and a pinch roller transmission mechanism, which are prior arts and can be obtained by procurement. The guiding and cutting device 4 further includes a mounting bracket, and both the tape cutting mechanism and the pinch roller transmission mechanism are installed on the above-mentioned mounting bracket. Among them, the tape cutting mechanism mainly includes a cutting platform fixedly connected to the mounting bracket. A cutting knife is arranged above the cutting platform, and a linear driving member for driving the cutting knife to move longitudinally is also included. In this embodiment, the linear driving member adopts a solenoid valve push rod. The pinch roller transmission mechanism mainly includes a lower roller seat fixedly connected to the mounting bracket. A driving roller is rotatably connected to the above-mentioned lower roller seat. A longitudinally arranged guide rod is screwed on the lower roller seat, and an upper roller seat is slidably penetrated through the guide rod. A spring located above the upper roller seat is penetrated through the above-mentioned guide rod. A driven roller is rotatably connected to the upper roller seat, and a motor for driving the driving roller to rotate is also included.

[0052] By setting the label output assembly, the cutting and printing operations of the label can be realized, and the label printed with information can be ejected onto the label taking box 1. At the same time, the required test tube 100 is selected by using the dropping tube device 17, and the dropping tube operation of the above test tube is realized. At the same time, the driven pinch roller structure 10, the roller moving device 11 and the tube pushing device 12 work together to achieve the purpose of receiving and pushing out the test tube 100, so that the pushed-out test tube slides from the material guiding plate 2 to the label taking box 1, which is convenient for the operator to take out the label and the sample test tube to be labeled at the same time, saving the process of the operator searching for the sample test tube, simplifying the process of manual labeling operation, improving the applicability of the test tube labeling machine, enabling the labeling machine to automatically realize the operations of dropping tube, clamping tube, label peeling, labeling and tube discharging, and being able to automatically supply single labels adhered with substrates and sample test tubes that meet the requirements, enabling the operator to synchronously take out a single label adhered with a substrate and a sample test tube at one time, which is convenient for the staff to paste the above single label at a specific position on the sample test tube. It improves the applicability of the test tube labeling machine and improves the working efficiency of the manual labeling operation process when necessary.

[0053] See further Figure 7, in this embodiment, the housing structure 19 includes a base plate 19-1. Two sets of side brackets 19-2 are fixedly connected to the base plate 19-1 in a relatively arranged manner, and a first back panel bracket 19-3 is fixedly connected to each side bracket 19-2. An installation back panel 19-5 is arranged between the two sets of side brackets 19-2 and is connected to each side bracket 19-2 through the first back panel bracket 19-3. In this embodiment, the roller moving device 11, the active pinch roller device 13, and the label supply device 9 are all connected to the installation back panel 19-5; it also includes a second back panel bracket 19-4 fixedly connected to each side bracket 19-2. The downpipe device 17 is fixedly connected to the housing structure 19 through the two sets of second back panel brackets 19-4. The housing structure 19 further includes a back panel, a front panel, and a top panel (not shown in the figure) connected to the two sets of side brackets 19-2. A maintenance window is opened on the front panel and a maintenance door is arranged at the maintenance window. A tube discharge window corresponding to each storage tube cavity 18 is opened on the top panel and a flip cover is hinged at the tube discharge window.

[0054] In order to detect whether the label content on the test tube after the labeling operation is completed is correct and avoid medical accidents caused by information errors, this embodiment further includes a sensor mounting bracket installed on the second sliding tube base plate 17-13 and located between the tube discharge funnel structure 14 and the active pinch roller device 13. A code scanning sensor 101 is installed on the sensor mounting bracket. After the test tube labeling operation is completed and before the test tube is pushed out, the roller moving device 11 drives the driven pinch roller structure 10 to move below the code scanning sensor 101, so that the code scanning sensor 101 can scan the label on the test tube supported by the driven pinch roller structure 10, and then check the information on the label.

[0055] This embodiment further includes an electric control operating member installed on the housing structure 19. The electric control operating member mainly includes a PLC controller and a touch display screen connected to the PLC controller. The PLC controller is connected to the power supply circuit. Each linear driving member and rotating driving motor in the labeling machine are connected to the control end of the PLC controller. Each sensor in the labeling machine is connected to the detection end of the PLC controller. The PLC controller receives the detection information of each sensor, the PLC controller obtains and displays the detection information through the touch display screen, the PLC controller automatically controls the corresponding actions of each linear driving member and rotating driving motor after judgment, or sends an instruction through the touch display screen, and the PLC controller controls the corresponding actions of the linear driving member and rotating driving motor after receiving the instruction.

[0056] Working process:

[0057] Different kinds of test tubes 100 are stacked horizontally and placed in different tube storage chambers 18. Test tubes in the tube storage chamber 18 that meet the requirements are selected according to the types of test tubes 100 to be labeled. The corresponding thumbwheel motor 17-4 drives the corresponding discharge thumbwheel 17-10 in the tube storage chamber 18 to rotate, so that the test tubes 100 at the bottom of the tube storage chamber 18 fall into the test tube accommodating groove 17-11, and fall onto the first slide tube bottom plate 17-12 or the second slide tube bottom plate 17-13 as the discharge thumbwheel 17-10 rotates, and fall into the tube outlet flat cylinder 14-1 in a correct posture under the guidance of the first slide tube bottom plate 17-12 or the second slide tube bottom plate 17-13. At this time, the tube blocking plate 16-1 in the tube blocking device 16 is inserted into the tube connecting groove 14-2 to close the discharge port of the tube outlet flat cylinder 14-1, thereby realizing the automatic tube dropping operation of the labeling machine.

[0058] After the above-mentioned tube dropping operation is completed, the roller moving device 11 is started, driving the driven clamping roller structure 10 to move to the pipe connection position at the outlet of the tube flat cylinder 14-1, and the pipe blocking driving member 16-4 in the pipe blocking device 16 is started to drive the pipe blocking plate 16-1 to move to the outside of the pipe connection slot 14-2, so that the test tube 100 falls onto the driven clamping roller structure 10, and the sensor installed on the roller moving device 11 detects whether the position of the test tube on the driven clamping roller structure 10 meets the labeling requirements. If If the requirements are not met, the test tube positioning device 15 starts to push the test tube 100, so that the tube cap of the test tube 100 contacts the inner wall of the tube outlet flat cylinder 14-1, thereby realizing the position adjustment operation of the test tube 100. After completing the above operation, the roller moving device 11 starts again to drive the test tube 100 to move until the outer peripheral wall of the tube body of the test tube 100 is tightly contacted with the outer peripheral surface of the active clamping roller 13-1 in a tangential manner, and the clamping roller motor 13-3 starts to drive the active clamping roller 13-1 to rotate, thereby driving the clamped test tube 100 to rotate; when the test tube 100 rotates, the label supply device 9 provides the label of the peeled base band, and makes the label extend between the active clamping roller 13-1 and the test tube 100, so that the label is attached to the outer peripheral wall of the test tube 100; when the test tube 100 completes the above-mentioned labeling operation, the roller moving device 11 starts to drive the test tube 100 to move in the direction away from the active clamping roller device 13. If necessary, the test tube that has completed the labeling operation needs to be driven to move to the code scanning sensor 101 is checked for information. After the above operation is completed, the test tube 100 is moved to the top of the feed port of the sliding guide plate 2 and faces the blanking baffle 20 in the horizontal direction. The tube pushing device 12 is started to push the test tube 100, so that the test tube 100 falls onto the sliding guide plate 2 under the blocking and limiting action of the blanking baffle 20, and falls into the material box 1 along the sliding guide plate 2, so that the operator can take out the material box 1 and take the test tube 100 that has completed the labeling operation.

[0059] When it is necessary to manually paste a specific label at a specific position on the sample test tube, start the label output assembly to cut and print the label, and spit out the label printed with information onto the material picking box 1. At the same time, use the tube dropping device 17 to select the required test tube 100 and perform the tube dropping operation of the above test tube. At the same time, the driven pinch roller structure 10, the roller moving device 11 and the tube pushing device 12 work together to achieve the purpose of receiving and pushing out the test tube 100, so that the pushed-out test tube slides down from the material sliding guide plate 2 onto the material picking box 1, facilitating the operator to take out the label and the sample test tube to be labeled at the same time.
