Abstract
Description
Technical Field
[0001] This utility model relates to labels for injection pens, and in particular to a buffer module for labeling injection pens. Background Technology
[0002] In the medical field, injection pens, as a commonly used drug delivery device, are widely used in the clinical treatment of various diseases such as diabetes and growth hormone therapy due to their advantages of convenient operation and accurate dosage. With the continuous growth of medical needs, the production scale of injection pens is also expanding, and the requirements for their production efficiency and quality are becoming increasingly stringent. Labeling, as one of the key steps in the injection pen production process, directly affects the clarity of the product's markings, the accuracy of information, and its appearance quality, thus impacting drug safety and the patient's medication experience.
[0003] In injection pen labeling production lines, the transfer and feeding of injection pens are crucial for ensuring labeling efficiency and quality. Traditional injection pen labeling production lines often employ simplistic methods for pen buffering and feeding. Generally, pens to be labeled are temporarily placed near the workbench, manually picked up one by one, and placed into fixed positions on a conveyor belt, which then transports them to the labeling station. This manual feeding method is not only labor-intensive and inefficient, but also prone to inconsistencies and inaccuracies due to the inherent uncertainties of manual operation. This can lead to positional shifts and tilting during transport, affecting labeling accuracy and increasing the defect rate. Furthermore, the transfer method is often imprecise, making it difficult to accurately place the pens into their designated positions on the conveyor belt. Traditional feeding devices mostly use simple gravity-feed or mechanical pushing methods, which can cause collisions and accumulation of pens as they enter the conveyor belt, leading to chaos during transport. This not only affects labeling efficiency but can also damage the pens.
[0004] The existing technical solutions have the following drawbacks: high manual labor intensity, low production efficiency, and difficulty in ensuring the consistency and accuracy of injection pen placement. Utility Model Content
[0005] The purpose of this invention is to provide a buffer module for labeling injection pens to solve the problems existing in the prior art.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A buffer module for labeling injection pens includes a worktable;
[0008] A conveyor belt is fixedly installed on the top of the workbench, and the conveyor belt transports injection pens from right to left.
[0009] The buffer feeding module is provided in two parts, both of which are located on the top of the workbench and are symmetrically fixedly installed at the front and rear ends of the conveyor belt.
[0010] The conveyor belt is provided with multiple fixed blocks, which are evenly arranged around its outer surface. On the side of the fixed block facing away from the conveyor belt surface, multiple slots are evenly spaced along the conveyor belt transport direction and are all through the front and back. The buffer feeding module is used to transfer the buffered injection pen from top to bottom into the slots of the fixed block.
[0011] By adopting the above technical solution, the injection pen is first placed on the top of the buffer feeding module. The buffer feeding module then transfers the buffered injection pen from top to bottom into the slot of the fixed block. The conveyor belt then transports it to the next stage. Through automated operation, manual labor is saved, production efficiency is increased, and the consistency and accuracy of injection pen placement are ensured.
[0012] In a further embodiment, the buffer loading module includes:
[0013] A lifting module, wherein multiple lifting modules are provided, and the lifting modules are respectively fixedly installed on the side of the conveyor belt away from the conveyor belt;

The distance between the center lines of adjacent fixing blocks that are close to each other in the left and right directions is equal to the distance between the center lines of adjacent slots. The distance between the center lines of adjacent placement slots that are close to each other in the left and right directions is equal to the distance between the center lines of adjacent placement slots.

[0020] The first cylinder, the fixed end of the first cylinder is fixedly installed on the bottom of the first mounting plate;
[0021] The support plate has its telescopic end passing through the first mounting hole of the first mounting plate and fixedly installed at the bottom of the support plate. The first cylinder is used to drive the support plate to move.
[0022] The first telescopic rod, and multiple first telescopic rods are provided. The first telescopic rods pass through the second clearance hole of the first mounting plate. The top end of the first telescopic rod is fixedly installed on the bottom of the bearing plate. The first telescopic rods are arranged parallel to each other.
[0023] The bottom end of the first telescopic rod is fixedly installed on the top of the first movable plate.
[0024] In a further embodiment, the adjustment module includes:
[0025] The second mounting plate is fixedly mounted on the top of the support plate. A second mounting hole that runs through the front and back is provided at the center of the front end of the second mounting plate. A third clearance hole that runs through the front and back is provided on the left and right sides of the front part of the second mounting plate.
[0026] The second cylinder, the fixed end of the second cylinder is fixedly installed on the side of the second mounting plate away from the conveyor belt;
[0027] The third mounting plate is fixedly mounted at the end of the third mounting plate away from the conveyor belt, with the telescopic end of the second cylinder passing through the second mounting hole of the second mounting plate. The second cylinder is used to drive the third mounting plate to move.
[0028] The second telescopic rod is provided in multiple ways. The second telescopic rod passes through the third clearance hole of the second mounting plate. The end of the second telescopic rod near the conveyor belt is fixedly installed on the end of the third mounting plate away from the conveyor belt. The first telescopic rod and the second telescopic rod have the same structure.
[0029] The second movable plate and the second telescopic rod are fixedly installed at one end of the second movable plate. The second movable plate and the first movable plate have the same structure.
[0030] In a further embodiment, the first mounting bracket includes:
[0031] A first slide bar, one end of which is fixedly installed at the front of the conveyor belt;
[0032] The first slider has a first straight hole that runs through it from left to right on its left side, and a second straight hole that runs through it from top to bottom on its top. The other end of the first slider rod passes through the first straight hole.
[0033] The second slide rod, one end of which passes through the second straight hole;
[0034] The second slider has a third straight hole that runs vertically through its top, and the other end of the second slider passes through the third straight hole. The front part of the second slider has a fourth straight hole that runs from front to back.
[0035] And a third slide rod, one end of which passes through the fourth straight hole, and a sensor is fixedly installed at the other end of the third slide rod.
[0036] In a further embodiment, a second mounting bracket is also included, comprising:
[0037] The third slider is fixedly installed at the front of the conveyor belt, and a fifth straight hole that runs vertically through the top of the third slider is provided.
[0038] The fourth slide rod, one end of which passes through the fifth straight hole;
[0039] The fourth slider has a sixth straight hole that runs vertically through its top and a seventh straight hole that runs from front to back through its front.
[0040] The fifth slide rod has one end inserted through the seventh straight hole, and a monitor is fixedly installed at the other end of the fifth slide rod.
[0041] By adopting the above technical solution, the first slider slides left and right on the first slider, the second slider slides up and down on the first slider, and the third slider moves back and forth on the second slider, allowing the sensor to move freely to the corresponding position. When two placement blocks are fixedly installed on one side of the adjustment module, the positions of the first, second, and third sliders can be adjusted to move the sensor to the corresponding position. When the sensor moves to the corresponding position, the first, second, and third sliders can be fixed with bolts. The fourth slider moves up and down on the third slider, and the fifth slider moves back and forth on the fourth slider. When the monitor moves to the corresponding position, the fourth and fifth sliders can be fixed with bolts. When the sensor and monitor detect that there is no injection pen in the placement slot of the placement block, the robot arm picks up the injection pen and puts it into the placement slot. One end of the injection pen has a protrusion that abuts against the inner wall of the placement slot, preventing the injection pen from rotating in the placement slot, facilitating subsequent transportation. The second cylinder is activated. The first cylinder starts, and its movable end moves the placement block back and forth. The second telescopic rod increases the load-bearing capacity of the movable end of the second cylinder to prevent vibration caused by the movable end of the second cylinder being unable to bear the load alone. This positions the two fixed blocks between the two placement blocks. The first cylinder starts, and its movable end moves the support plate downward. The first telescopic rod increases the load-bearing capacity of the movable end of the first cylinder. The downward movement of the support plate ensures that the height of the placement slot of the placement block is lower than the height of the slot of the fixed block, allowing the injection pen to be transported from the placement slot of the placement block to the slot of the fixed block without affecting the conveyor belt. When the injection pen moves into the slot of the fixed block, the conveyor belt starts, carrying the injection pen to the next stage. When the injection pen reaches the next stage, the first cylinder starts, and its movable end pushes the support plate upward to its original position. After the sensor and monitor detect that there is no injection pen in the placement slot of the placement block, the robot transports the injection pen to the placement slot of the placement block, thus completing one cycle.
[0042] In summary, this utility model has the following beneficial effects:
[0043] 1. By fixing one end of the first telescopic rod to the first movable plate, the stability of the bearing plate during up and down movement is increased. The second telescopic rod is fixedly installed to the second movable plate, which increases the stability of the placement block during forward and backward movement.
[0044] 2. By making the distance between the sides of adjacent placement blocks that are close to each other greater than the distance between the sides of adjacent fixed blocks that are far apart from each other, the placement blocks will not come into contact with or collide with the fixed blocks when they move up and down.
[0045] 3. The first, second, and third sliders can slide on the first and second sliders, allowing the sensor position to be adjusted when multiple blocks are placed simultaneously. This adapts to different numbers of blocks, thereby improving the sensor's detection effect on the injection pen. Attached Figure Description

[0054] Example 1:
[0055] like Figures 1-5 As shown, a buffer module for labeling injection pens includes a workbench 1, a conveyor belt 2, a buffer feeding module 3, and fixing blocks 4. The conveyor belt 2 is fixedly installed on the top of the workbench 1 and transports injection pens from right to left. Two buffer feeding modules 3 are provided, both located on the top of the workbench 1, and symmetrically fixed at the front and rear ends of the conveyor belt 2, respectively. Multiple fixing blocks 4 are provided, with multiple fixing blocks 4 evenly arranged circumferentially on the outer surface of the conveyor belt 2. Multiple slots are evenly spaced along the transport direction of the conveyor belt 2 on the side of the fixing blocks 4 facing away from the surface of the conveyor belt 2, and the multiple slots are all through the front and rear. The slots are semi-circular, and the diameter of the slots is slightly larger than the diameter of the injection pen, so that the slots can accommodate the injection pen. One end of the injection pen is provided with an integrally formed protrusion that fits into the slot, so that the injection pen cannot rotate in the slot, thereby restricting the movement of the injection pen and facilitating subsequent transport to the corresponding stage for processing. The buffer feeding module 3 is used to transfer the buffered injection pens from top to bottom into the slots of the fixing blocks 4.
[0056] The top end of the conveyor belt 2 is fixedly installed to the fixing block 4 by bolts. The fixing block 4 is made of non-rigid material, but has a certain load-bearing capacity, so that the fixing block 4 can move on the semi-circular arc of the conveyor belt 2 without obstructing the operation of the conveyor belt 2.
[0057] The buffer feeding module 3 includes a lifting module 31, an adjustment module 32, a guide plate 33, and a placement block 34. Two lifting modules 31 are provided, and the two lifting modules 31 are symmetrically fixedly installed on the front and rear sides of the conveyor belt 2. Two adjustment modules 32 are provided, and the two adjustment modules 32 are fixedly installed on the top of the lifting module 31. The lifting module 31 is used to move the adjustment module 32 in the up and down directions. One end of the guide plate 33 is fixedly installed on the end of the adjustment module 32 near the conveyor belt 2. The guide plate 33 is used to guide the injection pen into the placement slot of the placement block 34. One end of the placement block 34 is fixedly installed on the end of the adjustment module 32 near the conveyor belt 2. Multiple placement slots are provided on the top of the placement block 34 along the movement direction of the conveyor belt 2. The other end of the guide plate 33 is fixedly installed on the other end of the placement block 34.
[0058] The distance between the sides of the fixed blocks 4 that are far apart is less than the distance between the sides of the placement blocks 34 that are close together. That is, when the placement blocks 34 move downward, the fixed blocks 4 will not affect the movement of the placement blocks 34, so that the fixed blocks 4 are located in the gap between the placement blocks 34. The distance between the center lines of two adjacent slots is the same as the distance between the center lines of two adjacent placement slots. The distance between the center lines of the adjacent fixed blocks 4 in the left and right directions that are close to each other in the slots is equal to the distance between the center lines of the adjacent slots. The distance between the center lines of the adjacent placement blocks 34 in the left and right directions that are close to each other in the placement slots is equal to the distance between the center lines of the adjacent placement slots.
[0059] The lifting module 31 includes a first mounting plate 311, a first cylinder 312, a support plate 313, a first telescopic rod 314, and a first movable plate 315. The first mounting plate 311 is fixedly installed on the outside of the conveyor belt 2. A first mounting hole penetrating vertically is provided at the top center of the first mounting plate 311. Second clearance holes penetrating vertically are provided on the top left and right sides of the first mounting plate 311. The fixed end of the first cylinder 312 is fixedly installed on the bottom of the first mounting plate 311. The telescopic end of the first cylinder 312 passes through the first mounting hole of the first mounting plate 311 and is fixedly installed on the bottom of the support plate 313. The first cylinder 312 is used to drive the support plate 313 to move. Multiple first telescopic rods 314 are provided. The first telescopic rods 314 pass through the second clearance holes of the first mounting plate 311. The top end of the first telescopic rod 314 is fixedly installed on the bottom of the support plate 313. The first telescopic rods 314 are arranged parallel to each other. The bottom end of the first telescopic rod 314 is fixedly installed on the top of the first movable plate 315.
[0060] The adjustment module 32 includes a second mounting plate 321, a second cylinder 322, a third mounting plate 323, a second telescopic rod 324, and a second movable plate 325. The second mounting plate 321 is fixedly mounted on the top of the support plate 313. A second mounting hole penetrating from front to back is opened at the center of the front end of the second mounting plate 321. A third clearance hole penetrating from front to back is opened on both the left and right sides of the front part of the second mounting plate 321. The fixed end of the second cylinder 322 is fixedly mounted on the side of the second mounting plate 321 away from the conveyor belt 2. The telescopic end of the second cylinder 322 passes through the second mounting hole of the second mounting plate 321 and connects with the second cylinder 322. The third mounting plate 323 is fixedly installed at the end furthest from the conveyor belt 2. The second cylinder 322 is used to drive the third mounting plate 323 to move. Multiple second telescopic rods 324 are provided. The second telescopic rods 324 pass through the third clearance hole of the second mounting plate 321. The end of the second telescopic rod 324 near the conveyor belt 2 is fixedly installed at the end of the third mounting plate 323 furthest from the conveyor belt 2. The first telescopic rod 314 and the second telescopic rod 324 have the same structure. The other end of the second telescopic rod 324 is fixedly installed at one end of the second movable plate 325. The second movable plate 325 and the first movable plate 315 have the same structure.
[0061] The first mounting bracket 5 includes a first slide bar 51, a first slider 52, a second slide bar 53, a second slider 54, and a third slide bar 55. One end of the first slide bar 51 is fixedly mounted on the front of the conveyor belt 2. The left side of the first slider 52 has a first through-hole, and the top of the first slider 52 has a second through-hole. The other end of the first slide bar 51 passes through the first through-hole. One end of the second slide bar 53 passes through the second through-hole. The top of the second slider 54 has a third through-hole, and the other end of the second slide bar 53 passes through the third through-hole. The front of the second slider 54 has a fourth through-hole, and one end of the third slide bar 55 passes through the fourth through-hole. The other end of the third slide bar 55 is fixedly mounted with a sensor 7. The first, second, and third slide bars allow for the installation of different numbers of placement blocks, increasing practicality.
[0062] The second mounting bracket 6 includes a third slider 61, a fourth slider 62, a fourth slider 63, and a fifth slider 64. The third slider 61 is fixedly installed at the front of the conveyor belt 2. The top of the third slider 61 has a fifth through hole that runs vertically through it. One end of the fourth slider 62 passes through the fifth through hole. The top of the fourth slider 63 has a sixth through hole that runs vertically through it. The front of the fourth slider 63 has a seventh through hole that runs front to back through it. One end of the fifth slider passes through the seventh through hole. The other end of the fifth slider 64 is fixedly mounted with a monitor 8.
[0063] The conveyor belt 2 operates intermittently. When the placement slot of the placement block contains ten injection pens, that is, when the conveyor belt 2 transports the ten injection pens away from the buffer feeding module 3, the conveyor belt 2 stops. This allows the buffer feeding module 3 to transfer injection pens to the fixing slots on the subsequent fixing blocks 4 of the conveyor belt 2, so that the fixing slots of the subsequent fixing blocks 4 on the conveyor belt 2 are equipped with injection pens, and so that the fixing blocks 4 at the top of the conveyor belt 2 all contain injection pens.
[0064] Specific implementation process: The first slider 52 slides left and right on the first slider 51, the second slider 53 slides up and down on the first slider 52, and the third slider 55 moves back and forth on the second slider 54, allowing the sensor 7 to move freely to the corresponding position. When two placement blocks 34 are fixedly installed on one side of the adjustment module, the positions of the first slider 51, the second slider 53, and the third slider 55 can be adjusted to move the sensor 7 to the corresponding position. When the sensor 7 moves to the corresponding position, the first slider 51, the second slider 53, and the third slider 55 can be secured with bolts. For fixation, the fourth slide bar 62 moves up and down on the third slide bar 61, and the fifth slide bar 64 moves back and forth on the fourth slide bar 63. When the monitor 8 moves to the corresponding position, the fourth slide bar 62 and the fifth slide bar 64 can be fixed with bolts. When the sensor 7 and the monitor 8 detect that there is no injection pen in the placement slot of the placement block 34, the robot arm picks up the injection pen and puts it into the placement slot. One end of the injection pen is provided with two protrusions, which abut against the inner wall of the placement slot, so that the injection pen cannot rotate in the placement slot, which facilitates subsequent transportation. The second cylinder 322 is started. The movable end of cylinder 322 drives the placement block 34 to move back and forth. The second telescopic rod 324 is used to increase the load-bearing capacity of the movable end of the second cylinder 322 to prevent vibration caused by the movable end of the second cylinder being unable to bear the load alone. This ensures that the two fixed blocks 4 are positioned between the two placement blocks 34. The first cylinder 312 is activated, and the movable end of the first cylinder 312 drives the support plate 313 to move, causing the support plate 313 to move downward. The first telescopic rod 314 is used to increase the load-bearing capacity of the movable end of the first cylinder 312. The downward movement of the support plate 313 should ensure that the height of the placement groove of the placement block 34 is lower than that of the fixed block 34. The height of the slot in block 4 allows the injection pen to be transported from the placement slot of the placement block 34 to the slot in the fixed block 4 without affecting the conveyor belt. When the injection pen moves into the slot in the fixed block 4, the conveyor belt 2 starts, carrying the injection pen to the next stage. When the injection pen reaches the next stage, the first cylinder 312 starts, and the movable end of the first cylinder 312 pushes the carrier plate 313 upward to its original position. After the sensor 7 and the monitor 8 detect that there is no injection pen in the placement slot of the placement block 34, the robot transports the injection pen into the placement slot of the placement block 34, thus completing one round of the process.
