Description

TECHNICAL FIELD

[0001] The application relates to the technical field of a test tube labeling process, in particular to a test tube labeling machine and a labeling process. BACKGROUND

[0002] Test tubes are used to collect liquid for testing, in order to distinguish test tubes of different patients, test labels corresponding to each patient are needed to be pasted on the test tubes, which are used to mark the patient and the corresponding liquid volume, testing type and the like.

[0003] At present, when medical staff use test tubes, the medical staff usually prints labels on label roll paper through a label printing device, then the medical staff takes the labels from the label roll paper and manually pastes the labels on the surface of the test tubes, so that the process of test tube labeling is complicated and greatly increases the workload of the medical staff. SUMMARY

[0004] In order to reduce the workload of the medical staff, the application provides a test tube labeling machine and a labeling process.

[0005] In a first aspect, the application provides a test tube labeling machine, which adopts the following technical scheme:

[0006] The test tube labeling machine comprises a label printing device, a machine case and a tube placing frame arranged in the machine case, a feeding port is formed in the top wall of the machine case and located in the direction of the tube placing frame, a back plate is fixedly arranged on the tube placing frame, a discharging port is formed in the back plate, a baffle is fixedly arranged on the top wall of the back plate and located below the discharging port, a guide plate is fixedly arranged on the tube placing frame and located below the back plate, a discharging port is formed in the side wall of the machine case, and the guide plate is in communication with the discharging port.

[0007] A sliding frame is slidably arranged in the discharging port, a top block is fixedly arranged on the sliding frame, the top block is used to prevent the test tube from entering the discharging port, a first driving assembly for driving the sliding frame to slide is arranged on the tube placing frame, a driving mechanism for driving the test tube to rotate is further arranged on the tube placing frame, a labeling frame is fixedly arranged in the machine case, and a labeling mechanism for pressing the label printed by the label printing device on the surface of the test tube is arranged on the labeling frame.

[0008] By adopting the above technical solution, when labeling test tubes, medical staff only need to place the test tube into the machine through the inlet. The test tube falls onto the back plate and slides down along the back plate. The top block prevents the test tube from sliding out of the discharge port. The test tube slides until it abuts against the baffle. The drive component drives the test tube to rotate, and the labeling mechanism presses the label printed on the label printing equipment onto the surface of the test tube. As the test tube rotates, the label is affixed to the test tube. After the test tube is labeled, the first drive component drives the sliding frame to slide, thereby opening the discharge port. The test tube falls through the discharge port onto the guide plate, and then slides from the tube rack outside the machine through the guide plate for medical staff to pick up. Therefore, medical staff do not need to manually label the test tubes, which greatly reduces their workload.

[0009] Optionally, the first drive assembly includes a first drive source, a transmission gear, and a rack. The transmission gear is rotatably mounted on the tube holder, the rack is fixedly connected to the sliding frame, and the transmission gear meshes with the rack. The first drive source is used to drive the transmission gear to rotate.

[0010] By adopting the above technical solution, the transmission gear is driven to rotate by the first driving source, and the rotation of the transmission gear drives the rack to slide, thereby driving the sliding frame to slide.

[0011] Optionally, the driving mechanism includes a first roller, a second roller, and a second driving assembly. An abutment roller is rotatably mounted on the sliding frame. The first roller and the second roller are both rotatably mounted on the tube holder, and the first roller and the second roller are both parallel to the axial direction of the abutment roller. The first roller, the second roller, and the abutment roller are all used to abut against the side wall of the test tube. The second driving assembly is used to drive the first roller to rotate.

[0012] By adopting the above technical solution, when the test tube slides to the baffle position, it comes into contact with the abutting roller. The first driving component drives the sliding frame to slide towards the first roller, thereby pushing the test tube to slide on the baffle. When the first roller, the second roller and the abutting roller are all in contact with the side wall of the test tube, the second driving component drives the first roller to rotate, thereby driving the test tube to rotate.

[0013] Optionally, a buffer block is slidably disposed on the sliding frame, and an elastic element is disposed on the sliding frame to drive the buffer block to slide away from the sliding frame, and the abutment roller is rotatably disposed on the buffer block.

[0014] By adopting the above technical solution, when the first roller, the second roller, and the abutting roller all come into contact with the test tube, a certain buffering force is applied to the abutting roller through the elastic element, which to a certain extent prevents the pressure of the first roller, the second roller, and the abutting roller on the test tube from being too strong and causing the test tube to break.

[0015] Optionally, an anti-slip sleeve is fitted onto the first roller.

[0016] By adopting the above technical solution, the transmission efficiency of the first roller to the test tube is increased by using an anti-slip sleeve, thereby improving the labeling quality of the test tube.

[0017] Optionally, the labeling mechanism includes a label picking block, a take-up roller, a servo motor, and a labeling assembly. The label picking block is fixedly mounted on the labeling frame, and a label picking tip is provided at one end of the label picking block near the tube frame. The label picking tip is used to separate the label from the label roll.

[0018] The take-up roller is rotatably mounted inside the machine housing, and the axial direction of the take-up roller is parallel to the axial direction of the first roller. The printed label on the label printing equipment passes around the label picking block and is wound around the take-up roller. The servo motor is fixedly mounted inside the machine housing, and the output shaft of the servo motor is coaxially and fixedly connected to the take-up roller. The labeling assembly is used to press the label separated from the label picking block onto the side wall of the test tube.

[0019] By adopting the above technical solution, the label printing equipment, while printing labels, drives the take-up roller to rotate via a servo motor to rewind the label roll, thus keeping the roll of paper between the take-up roller and the label printing equipment taut. When the label on the label roll passes the label-taking tip of the label-taking block, the label gradually separates from the label roll and extends towards the tube holder. When the label extends a certain distance, it comes into contact with the surface of the test tube. At this time, the labeling component presses the label firmly onto the side wall of the test tube. As the test tube rotates, the label is thus affixed to the test tube.

[0020] Optionally, the labeling assembly includes a pressure block and a driving member. The pressure block is slidably disposed on the labeling rack in a direction close to or away from the tube holder, and the pressure block is used to press the label separated from the labeling block onto the side wall of the test tube. The driving member is used to drive the pressure block to slide.

[0021] By adopting the above technical solution, after the label comes into contact with the test tube, the driving component drives the pressure block to slide towards the tube holder, thereby pressing the label firmly against the side wall of the test tube.

[0022] Optionally, a pressure roller is rotatably mounted on the pressure block, the axial direction of the pressure roller being parallel to the axial direction of the first roller, and the pressure roller being used to abut against the label.

[0023] By adopting the above technical solution, the pressure roller is connected to the label in a rolling manner, which effectively prevents the pressure block from scratching the label surface.

[0024] Optionally, a first positioning plate and a second positioning plate are slidably disposed on the tube placement rack. The first positioning plate and the second positioning plate are parallel to each other, and the first positioning plate and the second positioning plate are respectively used to abut against the two ends of the test tube. The sliding direction of the sliding frame is parallel to the first positioning plate. A third driving component is respectively disposed on the tube placement rack for driving the first positioning plate and the second positioning plate to slide.

[0025] By adopting the above technical solution, when the test tube slides to the baffle position, the first positioning plate and the second positioning plate are driven to slide by the third driving component and abut against both ends of the test tube, thereby positioning the labeling position of the test tube and improving the labeling accuracy.

[0026] Secondly, this application provides a labeling process for a test tube labeling machine, employing the following technical solution:

[0027] A labeling process for a test tube labeling machine includes the following steps:

[0028] S1. When labeling test tubes, medical staff put the test tubes into the machine box from the feed port. The test tubes fall onto the back plate and slide down the back plate. The top block prevents the test tubes from sliding down from the feed port. The test tubes slide until they come into contact with the baffle and the contact roller.

[0029] S2. When the test tube slides to the baffle position, the first positioning plate and the second positioning plate are driven to slide by the third driving component and abut against both ends of the test tube, thereby positioning the labeling position of the test tube.

[0030] S3. The sliding frame is driven to slide closer to the first roller by the first driving component, thereby pushing the test tube to slide on the baffle, so that the first roller, the second roller and the abutting roller are all pressed against the side wall of the test tube.

[0031] S4. While printing labels, the label printing equipment drives the take-up roller to rotate via a servo motor to take up the label roll, thus keeping the roll of paper between the take-up roller and the label printing equipment taut. When the label on the label roll passes the tip of the label taking block, the label gradually separates from the label roll and extends towards the tube rack. After the label extends a certain distance, it comes into contact with the surface of the test tube. The driving component drives the pressure block to slide towards the tube rack, thereby pressing the label firmly against the side wall of the test tube.

[0032] S5. The second drive component drives the first roller to rotate, and the first roller drives the test tube to rotate. As the test tube rotates, the label can be attached to the test tube. While the test tube is being labeled, the servo motor drives the take-up roller to continue rotating at a certain angle, so that the label can be smoothly removed from the label roll.

[0033] S6. After the test tubes are labeled, the top block is driven to slide by the first drive component, thereby opening the discharge port. The test tubes fall through the discharge port onto the guide plate, and then slide off the tube rack to the outside of the machine for medical staff to take away.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. When labeling test tubes, medical staff only need to place the test tube into the machine through the inlet. The test tube falls onto the back plate and slides down the back plate. The top block prevents the test tube from sliding out of the discharge port. The test tube slides until it abuts against the baffle. The drive component drives the test tube to rotate. Then, the labeling mechanism presses the label printed on the label printing equipment onto the surface of the test tube. As the test tube rotates, the label is applied to the test tube. After the test tube is labeled, the first drive component drives the top block to slide, thereby opening the discharge port. The test tube falls through the discharge port onto the guide plate and then slides off the tube rack outside the machine for medical staff to pick up. This eliminates the need for medical staff to manually label the test tubes, greatly reducing their workload.

[0036] 2. After the first roller, the second roller, and the abutting roller all come into contact with the test tube, a certain buffering force is applied to the abutting roller through the elastic element, which to a certain extent prevents the pressure of the first roller, the second roller, and the abutting roller on the test tube from being too great and causing the test tube to break.

[0037] 3. After the test tube slides to the baffle position, the first positioning plate and the second positioning plate are driven to slide by the third driving component and abut against both ends of the test tube, thereby positioning the labeling position of the test tube and improving the labeling accuracy.

[0058] Reference Figure 3 An anti-slip sleeve 361 is fitted on the first roller 36; the anti-slip sleeve 361 increases the transmission efficiency of the first roller 36 to the test tube, thereby improving the labeling quality of the test tube.

[0059] Reference Figure 3 , 6 The tube holder 3 is slidably mounted on the back plate 32 with a first positioning plate 323 and a second positioning plate 324. The first positioning plate 323 and the second positioning plate 324 are parallel and are respectively used to abut against the two sides of the test tube. The sliding direction of the sliding frame 34 is parallel to the first positioning plate 323.

[0060] Reference Figure 6The tube placement frame 3 is provided with a third drive assembly 39 for driving the first positioning plate 323 and the second positioning plate 324 to slide. The third drive assembly 39 includes a first pulley 391, a second pulley 392, a transmission belt 393 and a third motor 394.

[0061] Reference Figure 7 , 8 The labeling mechanism includes a label-taking block 131, a take-up roller 17, a servo motor 18, and a labeling assembly. The label-taking block 131 is fixedly mounted on the labeling frame 13. When the cover plate closes the opening end of the machine housing 1, the label-taking block 131 is close to the gap between the first roller 36 and the second roller 37. The label-taking block 131 is provided with a label-taking tip at one end close to the tube holder 3.

[0062] Reference Figure 7 A bracket is fixedly installed inside the housing 1. The take-up roller 17 is rotatably mounted on the bracket. The axial direction of the take-up roller 17 is parallel to the axial direction of the first roller 36. The label printed on the label printing device 2 passes around the label picking block 131 and is wound around the take-up roller 17. The servo motor 18 is fixedly installed inside the housing 1, and the output shaft of the servo motor 18 is coaxially and fixedly connected to the take-up roller 17. While printing the label, the label printing device 2 drives the take-up roller 17 to rotate through the servo motor 18 to wind up the label roll, so that the roll between the take-up roller 17 and the label printing device 2 is always in a taut state. When the label on the label roll passes the label picking tip of the label picking block 131, the label gradually separates from the label roll and extends towards the tube holder 3. After the label extends a certain distance, it abuts against the surface of the test tube.

[0063] Reference Figure 8The labeling assembly includes a pressure block 132 and a driving component 133. The pressure block 132 is slidably disposed on the labeling frame 13 in the direction of approaching or moving away from the tube holder 3, and the pressure block 132 is used to slide between the first roller 36 and the second roller 37. A pressure roller 1321 is rotatably disposed on one end of the pressure block 132 near the tube holder 3. The axial direction of the pressure roller 1321 is parallel to the axial direction of the first roller 36. The driving component includes a servo cylinder, which is fixedly disposed on the labeling frame 13. The piston rod of the servo cylinder is fixedly connected to the pressure block 132. After the label comes into contact with the test tube, the pressure block 132 is driven by the servo cylinder to slide towards the tube holder 3, thereby pressing the label onto the side wall of the test tube by the pressure roller 1321. As the test tube rotates, the label is affixed to the test tube. While the test tube is being labeled, the servo motor 18 drives the take-up roller 17 to continue rotating at a certain angle, so that the label can be smoothly detached from the label roll.

[0064] The implementation principle of a test tube labeling machine according to an embodiment of this application is as follows: Medical staff put test tubes into the machine box 1 through the feed port 12. The test tubes fall onto the back plate 32 and slide down along the back plate 32. The top block 341 prevents the test tubes from sliding down from the discharge port 321. The test tubes slide to abut against the baffle 322 and the abutting roller 343. When the test tubes slide to the position of the baffle 322, the first positioning plate 323 and the second positioning plate 324 are driven to slide by the third driving component 39 respectively, abutting against both ends of the test tube, thereby positioning the labeling position of the test tubes.

[0065] The first drive assembly 35 drives the sliding frame 34 to slide closer to the first roller 36, thereby pushing the test tube to slide on the baffle 322, so that the first roller 36, the second roller 37 and the abutment roller 343 are all pressed against the side wall of the test tube; while printing the label, the label printing device 2 drives the winding roller 17 to rotate through the servo motor 18 to wind up the label roll, so that the roll between the winding roller 17 and the label printing device 2 is always taut. When the label on the label roll passes the tip of the label picking block 131, the label gradually separates from the label roll and extends towards the tube holder 3. When the label extends a certain distance, it abuts against the surface of the test tube. The servo cylinder drives the pressure block 132 to slide closer to the tube holder 3, and the pressure roller 1321 presses the label firmly against the side wall of the test tube.

[0066] The second drive assembly 38 drives the first roller 36 to rotate, which in turn drives the test tube to rotate. As the test tube rotates, the label can be affixed to it. While the test tube is being labeled, the servo motor 18 drives the take-up roller 17 to continue rotating at a certain angle, so that the label can be easily removed from the label roll. After the test tube is labeled, the first drive assembly 35 drives the top block 341 to slide, thereby opening the discharge port 321. The test tube falls through the discharge port 321 onto the guide plate 33, and then slides off the tube rack 3 to the outside of the machine box 1 for medical staff to pick up. This eliminates the need for medical staff to manually label the test tubes, greatly reducing their workload.

[0067] This application also discloses a labeling process for a test tube labeling machine, including the following steps:

[0068] S1. When labeling test tubes, medical staff put the test tubes into the machine box 1 from the feed port 12. The test tubes fall onto the back plate 32 and slide down along the back plate 32. The top block 341 prevents the test tubes from sliding down from the discharge port 321. The test tubes slide until they abut against the baffle 322 and against the abutting roller 343.

[0069] S2. When the test tube slides to the position of the baffle 322, the first positioning plate 323 and the second positioning plate 324 are driven to slide by the third driving component 39 respectively, and abut against the two ends of the test tube, thereby positioning the labeling position of the test tube.

[0070] S3. The sliding frame 34 is driven to slide closer to the first roller 36 by the first driving component 35, thereby pushing the test tube to slide on the baffle 322, so that the first roller 36, the second roller 37 and the abutting roller 343 are all pressed against the side wall of the test tube.

[0071] S4. While printing labels, the label printing device 2 drives the take-up roller 17 to rotate via the servo motor 18 to take up the label roll, so that the roll between the take-up roller 17 and the label printing device 2 is always taut. When the label on the label roll passes the tip of the label taking block 131, the label gradually separates from the label roll and extends towards the tube holder 3. When the label extends a certain distance, it comes into contact with the surface of the test tube. The driving component 133 drives the pressure block 132 to slide towards the tube holder 3, thereby pressing the label firmly against the side wall of the test tube.

[0072] S5. The second drive assembly 38 drives the first roller 36 to rotate, and the first roller 36 drives the test tube to rotate. As the test tube rotates, the label can be attached to the test tube. While the test tube is being labeled, the servo motor 18 drives the take-up roller 17 to continue rotating at a certain angle so that the label can be smoothly removed from the label roll.

[0073] S6. After the test tubes are labeled, the top block 341 is driven to slide by the first drive component 35, thereby opening the discharge port 321. The test tubes fall through the discharge port 321 onto the guide plate 33, and then slide from the tube rack 3 to the outside of the machine box 1 through the guide plate 33 for medical staff to take away.

7. The labeling process of a test tube labeling machine according to claim 6, characterized in that, Includes the following steps: S1. When labeling test tubes, medical staff put the test tubes into the machine box (1) from the feed port (12). The test tubes fall onto the back plate (32) and slide down along the back plate (32). The top block (341) prevents the test tubes from sliding down from the discharge port (321). The test tubes slide until they come into contact with the baffle (322) and the contact roller (343). S2. When the test tube slides to the position of the baffle (322), the first positioning plate (323) and the second positioning plate (324) are driven to slide by the third driving component (39) respectively, and abut against the two ends of the test tube, thereby positioning the labeling position of the test tube; S3. The sliding frame (34) is driven to slide closer to the first roller (36) by the first drive assembly (35), thereby pushing the test tube to slide on the baffle (322) so that the first roller (36), the second roller (37) and the abutting roller (343) are all pressed against the side wall of the test tube. S4. While printing labels, the label printing equipment (2) drives the take-up roller (17) to rotate via the servo motor (18) to take up the label roll, so that the roll between the take-up roller (17) and the label printing equipment (2) is always taut. When the label on the label roll passes the tip of the label taking block (131), the label gradually separates from the label roll and extends towards the tube holder (3). When the label extends a certain distance, it comes into contact with the surface of the test tube. The driving component (133) drives the pressure block (132) to slide towards the tube holder (3), thereby pressing the label onto the side wall of the test tube. S5. The second drive assembly (38) drives the first roller (36) to rotate. The first roller (36) drives the test tube to rotate. As the test tube rotates, the label can be attached to the test tube. While the test tube is being labeled, the servo motor (18) drives the take-up roller (17) to continue rotating at a certain angle so that the label can be smoothly removed from the label roll. S6. After the test tubes are labeled, the top block (341) is driven to slide by the first drive component (35), thereby opening the discharge port (321). The test tubes fall through the discharge port (321) onto the guide plate (33), and then slide from the tube rack (3) to the outside of the machine (1) through the guide plate (33) for medical staff to take away.
