Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical equipment technology, and specifically to a conveying structure for an injection bottle filling line. Background Technology
[0002] In the pharmaceutical and biological agent industries, ampoules are the most common type of injection vial. As a common drug packaging container, the seal integrity of ampoules directly affects the quality and safety of drugs. Therefore, leak detection equipment is required during the ampoule production process to check for leakage defects. Traditional leak detection equipment typically includes a conveying mechanism, an infeed star wheel, and a conveying screw. The star wheel separates the ampoules, and the screw conveys them at a fixed distance, allowing the ampoules to pass through the detection station sequentially. However, in actual operation, ampoules need to undergo posture changes from vertical to horizontal and back to vertical to meet the requirements of different detection stages.
[0003] However, current conveying systems of this type have a significant drawback: the distance between the baffle and the conveying screw cannot be adjusted. This limitation causes numerous intractable problems in actual production. First, ampoule posture adjustment is severely affected. Because the fixed spacing is difficult to accommodate different ampoules, and the ampoules are obstructed during posture changes, when the spacing is too large, the ampoules wobble excessively in a horizontal position and struggle to return to an upright position smoothly; when the spacing is too small, the ampoules cannot complete the posture change properly and may even be squeezed and stuck. This results in inaccurate ampoule posture, with frequent instances of tilting or tipping, severely affecting the positioning and operation of subsequent processes and significantly increasing the defect rate. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a conveying structure for an injection bottle filling line.
[0005] This application provides a conveying structure for an injection vial filling line, which adopts the following technical solution:
[0006] A conveying device for an injection vial filling line includes a machine base, a conveying mechanism, an inlet star wheel, and a conveying screw. The conveying screw has a first baffle and a third baffle on each side. The machine base is equipped with an adjusting component for adjusting the distance between the first baffle, the third baffle, and the conveying screw. The adjusting component includes a locking screw and a clamping block. A positioning plate is mounted on the machine base. The first baffle is fixed to the positioning plate. Both ends of the third baffle and the positioning plate have oblong holes perpendicular to the direction of movement of the conveying screw. The clamping block has a connecting hole. The locking screw passes through the connecting hole and the oblong hole to thread-fix the third baffle and the positioning plate to the machine base. By loosening or tightening the locking screw, the third baffle and the positioning plate can move along the length of the oblong hole, thereby adjusting the distance between the first baffle, the third baffle, and the conveying screw.
[0007] By adopting the above technical solution, the distance between the first baffle, the third baffle, and the conveying screw can be flexibly adjusted according to the size of ampoules of different specifications. When the ampoule specifications change, the locking screw is loosened, allowing the third baffle and the positioning plate to move along the oblong hole. The distance is adjusted to a suitable value, and then the locking screw is tightened to fix it. This effectively solves the problem in traditional conveying systems where the fixed distance cannot adapt to different ampoules, avoiding swaying, jamming, tilting, or tipping of ampoules during posture changes due to improper distance. It ensures the accuracy of ampoule posture adjustment and provides a guarantee for the smooth progress of subsequent processes.
[0008] Preferably, a first guide area is provided at one end of the first baffle, a second guide area is provided at the end of the first baffle away from the first guide area, and a second baffle is provided between the first guide area and the second guide area.
[0009] By adopting the above technical solution, the first guiding area can smoothly push the vertically placed ampoule to a horizontal position after it enters the conveying screw. The second guiding area can then gradually straighten the horizontal ampoule back to a vertical position, achieving a smooth posture transition of the ampoule during the conveying process. Furthermore, when the ampoule is in the horizontal conveying stage, the second baffle works in conjunction with the third baffle to form a stable horizontal conveying channel, effectively limiting the horizontal displacement of the ampoule, helping to stabilize the bottle body, reducing the impact of vibration on the ampoule's posture, and ensuring that the ampoule can smoothly pass through the inspection station, further improving the accuracy and stability of the inspection.
[0010] Preferably, the first guide area includes a first guide plate and a first guide piece. The first guide plate is fixedly installed on the side of the first baffle near the bottle inlet star wheel, and the first guide piece is fixedly installed on the side of the third baffle near the first guide plate. The first guide plate is a gradually widening slope, and the first guide piece is a gradually narrowing slope.
[0011] By adopting the above technical solution, when the ampoule is driven into the first guide area by the conveying screw, the ampoule body slides synchronously along the gradually widening inclined surface of the first guide plate and the gradually narrowing inclined surface of the first guide piece. The first guide plate expands outward, pushing the middle of the ampoule body to gradually tilt, changing the center of gravity of the ampoule; the first guide piece contracts inward, limiting the deviation of the ampoule opening and preventing excessive shaking or deviation from the track during the tilting process. The combined effect of these two mechanisms allows the center of gravity of the ampoule to shift smoothly downward, achieving uniform tilting and ensuring that the ampoule can safely and stably change from a vertical to a horizontal position in the initial stage of posture transformation, effectively avoiding collisions and damage caused by excessively rapid tilting or uneven force.
[0012] Preferably, the second guide area includes a second guide plate and a second guide piece. The second guide plate is fixedly installed on the side of the first baffle away from the bottle inlet star wheel, and the second guide piece is fixedly installed on the side of the third baffle close to the second guide plate. The second guide plate and the second guide piece have the same shape as the first guide plate and the first guide piece and are symmetrically arranged.
[0013] By adopting the above technical solution, when the ampoule enters the second guide area in a horizontal state, the narrow end of the second guide plate contacts the bottle body first. As the conveying screw rotates, it begins to apply an upward lifting force. Simultaneously, the wide end of the second guide plate lightly touches the top of the bottle body, providing lateral restraint and preventing excessive shaking of the bottle. As the ampoule continues to be conveyed, the second guide plate and the second guide plate, through their complementary shapes and synergistic effect, gradually straighten the bottle body, allowing the ampoule to smoothly transition from a horizontal to a vertical position. This symmetrically arranged guide structure ensures that the ampoule can also accurately and stably complete the straightening action in the latter half of the posture transition, further improving the success rate of ampoule posture transition and reducing the probability of defective products.
[0014] Preferably, a stop is provided between the first guide plate and the second guide plate, the stop is fixedly installed on the third baffle, and the two ends of the stop are smoothly connected to the ends of the first guide plate and the second guide plate.
[0015] By adopting the above technical solution, the stop block fills the gap between the end of the first guide plate and the beginning of the second guide plate, preventing the ampoule from rolling or tilting due to loss of lateral constraint during the horizontal transport phase. During the horizontal transport of the ampoule, the stop block continuously provides stable lateral support, ensuring that the ampoule remains on the correct transport track and guaranteeing its posture stability throughout the entire transport process.
[0016] Preferably, the conveying mechanism is fixedly connected to the machine base, the output end of the conveying mechanism is connected to the input end of the bottle inlet star wheel, and the bottle inlet star wheel is rotatably mounted on the machine base.
[0017] By adopting the above technical solution, the conveying mechanism can stably push the ampoules into the toothed grooves of the infeed star wheel, providing a continuous power source for the infeed star wheel. The infeed star wheel, through rotation, separates the densely packed ampoules into a single row, ensuring consistent spacing between each ampoule. This allows the ampoules to enter the conveying screw in an orderly manner, achieving initial sorting and positioning of the ampoules and guaranteeing the continuity and stability of the entire conveying process.
[0018] Preferably, the conveying screw has a spiral groove for conveying ampoules.
[0019] By adopting the above technical solution, when the conveying screw rotates, the ampoule can move stably along the trajectory of the spiral groove, achieving fixed-distance conveying. This design not only ensures the positional accuracy of the ampoule during the conveying process, but also avoids slippage or deviation of the ampoule during conveying.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. The spacing between the first and third baffles and the conveying screw can be flexibly adjusted according to the size of ampoules of different specifications. When the ampoule specifications change, loosen the locking screw to allow the third baffle and positioning plate to move along the oblong hole, adjust the spacing to the appropriate value, and then tighten the locking screw to fix it. This effectively solves the problem of traditional conveying systems being unable to adapt to different ampoules due to fixed spacing, and avoids swaying, jamming, tilting, or tipping of ampoules during posture changes due to improper spacing, ensuring the accuracy of ampoule posture adjustment and providing a guarantee for the smooth progress of subsequent processes.
[0022] 2. The first guide zone smoothly pushes the vertically placed ampoule to a horizontal position after it enters the conveyor screw. The second guide zone gradually straightens the horizontal ampoule back to an vertical position, achieving a smooth posture transition during the conveying process. The second baffle, working in conjunction with the third baffle, forms a stable horizontal conveying channel when the ampoule is in the horizontal conveying stage. This effectively limits the horizontal deviation of the ampoule, helps stabilize the bottle, reduces the impact of vibration on the ampoule's posture, and ensures that the ampoule can smoothly pass through the inspection station, further improving the accuracy and stability of the inspection.
[0023] 3. When the ampoule is driven into the first guide area by the conveying screw, the ampoule body slides synchronously along the gradually widening inclined surface of the first guide plate and the gradually narrowing inclined surface of the first guide piece. The first guide plate expands outward, pushing the middle of the ampoule body to gradually tilt, changing the center of gravity of the ampoule; the first guide piece contracts inward, limiting the deviation of the ampoule opening and preventing excessive shaking or deviation from the track during tilting. The combined effect of these two mechanisms ensures that the center of gravity of the ampoule shifts smoothly downward, achieving uniform tilting. This ensures that the ampoule can safely and stably change from a vertical to a horizontal position in the initial stage of posture transformation, effectively avoiding collisions and damage caused by excessively rapid tilting or uneven force.

[0027] This application discloses a conveying structure for an injection vial filling line.
[0028] A conveying structure for an injection vial filling line, as described in the following figure. Figure 1 and Figure 2 The system includes a machine base 1, a conveying mechanism 2, a bottle-feeding star wheel 3, and a conveying screw 4. The conveying mechanism 2 is located on one side of the machine base 1. The bottle-feeding star wheel 3 is rotatably mounted on the side of the machine base 1 near the conveying mechanism 2, and the output end of the output mechanism is connected to the bottle-feeding star wheel 3. The conveying screw 4 is rotatably mounted on the machine base 1 and is provided with a spiral groove 41 for conveying ampoules. The output end of the bottle-feeding star wheel 3 is connected to the input end of the conveying screw 4. A first baffle 5 is provided on one side of the conveying screw 4. A first guide area 51 is provided at one end of the first baffle 5, and a second guide area 52 is provided at the end of the first baffle 5 away from the first guide area 51. A second baffle 6 is provided between the first guide area 51 and the second guide area 52. A third baffle 7 is provided on the side of the conveying screw 4 away from the first baffle 5 and is detachably mounted on the machine base 1.
[0029] Specifically, the conveying screw 4 is located between the first baffle 5 and the third baffle 7. A positioning plate 8 is detachably installed on the machine base 1, and the first baffle 5 is fixedly installed on the positioning plate 8. An adjustment component 9 is provided on the machine base 1. The adjustment component 9 is used to adjust the distance between the first baffle 5, the third baffle 7 and the conveying screw 4. The third baffle 7 and the positioning plate 8 can be moved away from or closer to the conveying screw 4 through the adjustment component 9.
[0030] Furthermore, the adjusting assembly 9 includes a locking screw 91 and a clamping block 92. The two ends of the third baffle 7 and the positioning plate 8 are respectively provided with oblong holes 10, and the oblong holes 10 are opened perpendicular to the movement direction of the conveying screw 4. The clamping block 92 is provided with a connecting hole. The locking screw 91 passes through the connecting hole and the oblong hole 10 and is bolted to the machine base 1 for fixation. When the locking screw 91 is connected to the machine base 1, the clamping block 92 will abut against the surface of the third baffle 7 and the positioning plate 8 as the locking screw 91 is tightened. When it is necessary to adjust the distance between the first baffle 5 and the third baffle 7 and the conveying screw 4, the locking screw 91 is turned counterclockwise so that the locking screw 91 and the clamping block 92 no longer press the third baffle 7 and the positioning plate 8. At this time, the third baffle 7 and the positioning plate 8 can move along the length direction of the oblong hole 10, so that they are closer to or farther away from the conveying screw 4. After adjustment, tighten the locking screw 91 to firmly fix the third baffle 7 and the positioning plate 8 on the machine base 1 to prevent displacement during operation.
[0031] Specifically, the first guiding area 51 includes a first guide plate 511 and a first guide piece 512. The first guide plate 511 is fixedly installed on the side of the first baffle 5 near the input end, and the first guide piece 512 is fixedly installed on the side of the third baffle 7 near the first guide plate 511. The first guide plate 511 and the first guide piece 512 are positioned opposite each other. The first guide plate 511 has a gradually widening slope design, and the first guide piece 512 has a gradually narrowing slope design, so that the ampoule gradually changes from a vertical direction to a horizontal direction. When the ampoule is driven into the first guiding area 51 by the conveying screw 4, the ampoule body slides synchronously along the gradually widening slope of the first guide plate 511 and the gradually narrowing slope of the first guide piece 512. The first guide plate 511 expands outward, pushing the middle of the ampoule body to gradually tilt; the first guide piece 512 contracts inward, limiting the offset of the ampoule mouth. The two work together to force the center of gravity of the ampoule body to shift downward, achieving uniform tilting.
[0032] Specifically, the second guide area 52 includes a second guide plate 521 and a second guide piece 522. The second guide plate 521 is fixedly installed on the side of the first baffle 5 near the output end, and the second guide piece 522 is fixedly installed on the side of the third baffle 7 near the second guide plate 521. The second guide plate 521 and the second guide piece 522 have the same shape as the first guide plate 511 and the first guide piece 512 and are symmetrically arranged. When the ampoule enters the second guide area 52 in a horizontal state, the narrow end of the second guide piece 522 contacts the bottle body first. As the conveying screw 4 begins to apply an upward lifting force, the wide end of the second guide plate 521 simultaneously touches the top of the bottle body, providing lateral restraint and preventing the bottle from shaking excessively. As the ampoule continues to be conveyed, the second guide plate 521 and the second guide piece 522, through their complementary shapes and synergistic effect, gradually straighten the bottle body, allowing the ampoule to smoothly change from a horizontal to a vertical position.
[0033] Furthermore, a stop 11 is provided between the first guide plate 512 and the second guide plate 522. The stop 11 is fixedly installed on the third baffle 7. The two ends of the stop 11 are smoothly connected to the ends of the first guide plate 512 and the second guide plate 522 to ensure that the ampoule maintains a stable posture during the horizontal transport stage. The stop 11 fills the gap between the end of the first guide plate 512 and the beginning of the second guide plate 522 to prevent the ampoule from rolling or tilting due to loss of lateral constraint during the horizontal transport stage.
[0034] The implementation principle of the application embodiment is as follows: the conveying mechanism 2 sends the ampoules to the infeed star wheel 3, which separates them into a single row before feeding them into the conveying screw 4. The spiral groove 41 on the screw is used for fixed-distance conveying. The conveying screw 4 is provided with first and third baffles 7 on both sides. The adjustment component 9 on the machine base 1 can adjust the distance between the baffles and the screw to accommodate ampoules of different specifications. The first baffle 5 has first and second guide areas 52, with a second baffle 6 between them. The first guide plate 511 and the first guide piece 512 of the first guide area 51 cooperate to change the ampoule from vertical to horizontal; the second guide plate 521 and the second guide piece 522 of the second guide area 52 are symmetrically arranged to straighten the horizontal ampoule to vertical. The stop block 11 between the first and second guide pieces 522 can prevent the ampoule from rolling or tilting during horizontal conveying, ensuring the stability and accuracy of the entire conveying and posture conversion process, and improving detection accuracy and production efficiency.
[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
