Description

Technical Field

[0001] The present invention relates to a capping device and a medicine production system. Background Art

[0002] In the production of food and medicine, some processes require fermentation of materials stored in containers. Accordingly, materials need to be added to the container first, and then the container is closed by the cover. For large-scale capping processes, some related technologies use a linear conveyor belt to input the bottles one by one into a large wheel. The large wheel rotates according to a certain pause rhythm. When the bottle rotates with the large wheel to the corresponding capping station, it pauses for a short time, and during this period, the capping mechanism performs a screwing capping operation. Summary of the invention

[0003] The inventor has found through research that if the linear conveyor belt in the related art conveys the bottle body to the large wheel at a high speed, it is easy to cause impact to the large wheel or the bottle body, affecting the stability of the wheel rotation or damaging the bottle body, and reducing the conveying speed of the linear conveyor belt will affect the overall work efficiency. In addition, during the capping process, the bottle body needs to be held by the mechanism on the large wheel, and then the capping mechanism needs to stably perform the capping operation in a paused state. This working method has a relatively low capping efficiency, which will also affect the overall work efficiency.

[0047] Figure 1 It is a schematic structural diagram of some embodiments of the cover closing device according to the present disclosure. Figure 2 This is a schematic diagram of the structure of some embodiments of the lid closing device disclosed in the present invention, with a portion of the frame and the lid closing mechanism removed from a top view. Figure 1 and Figure 2 In some embodiments, the capping device includes: a frame 10, a first wheel disc 20, a second wheel disc 30, a third wheel disc 40 and a capping mechanism 50. The frame 10 may have a supporting surface for supporting each wheel disc and the bottle body, and also has a structure such as a bracket for installing the capping mechanism.

[0048] The first wheel disc 20 is rotatably disposed on the frame 10 and has a plurality of circumferentially arranged bottle accommodation positions. The second wheel disc 30 is rotatably disposed on the frame 10 and has a plurality of circumferentially arranged bottle accommodation positions. The third wheel disc 40 is rotatably disposed on the frame 10 and has a plurality of circumferentially arranged bottle accommodation positions and a plurality of circumferentially arranged bottle cap accommodation positions. The rotation of the first wheel disc 20, the second wheel disc 30 and the third wheel disc 40 can be uniformly driven by a single power mechanism, or can be independently driven by multiple power mechanisms.

[0049] The capping mechanism 50 is disposed on the frame 10 and can perform the function of capping the bottle cap 93 on the bottle body 91. The capping mechanism 50 can achieve the capping operation by squeezing the bottle cap 93 downward. In order to facilitate the bottle cap 93 to be tightly capped on the bottle body 91 by squeezing, a bottle cap with a smooth inner surface and a bottle body with a smooth outer surface can be used, so that even if the bottle body and the bottle cap are continuously moved during the capping process, the gradual capping effect can be achieved.

[0050] When the first wheel 20, the second wheel 30 and the third wheel 40 are rotating, the multiple bottle accommodating positions in the first wheel 20 are respectively and sequentially connected with the multiple bottle accommodating positions in the second wheel 30 at the first handover position HO1, the multiple bottle accommodating positions in the second wheel 30 are respectively and sequentially connected with the multiple bottle accommodating positions in the third wheel 40 at the second handover position HO2, and the multiple bottle cap accommodating positions in the third wheel 40 pass through the second handover position HO2 respectively, and the cap closing mechanism 50 is configured to buckle the bottle cap 93 transferred by the third wheel 40 on the bottle body 91 connected by the second wheel 30 and the third wheel 40 at the second handover position HO2 in a manner of continuous downward extrusion at the second handover position HO2.

[0051] In this embodiment, the uncapped bottle body 91 is transferred to the second wheel disc 30 at the first transfer position HO1 by the continuous rotation of the first wheel disc 20, and the transfer of the bottle cap 93 and the capped bottle body 92 is taken into account by the continuous rotation of the third wheel disc 40. The continuous rotation of the second wheel disc 30 enables the uncapped bottle body 91 and the bottle cap 93 transferred by the third wheel disc 40 to arrive at the second transfer position HO2 synchronously, and the bottle cap 93 is buckled in the second transfer position HO2 by the cap closing mechanism 50 in a manner of continuous downward squeezing.

[0052] In this way, the transfer function of the first wheel 20 can avoid the bottle body 91 from being delivered to the second wheel 30 at an excessively fast speed, thereby reducing the impact of the bottle body 91 on the second wheel 30. The cooperation between the second wheel 30 and the third wheel 40 at the second handover position HO2 realizes the pre-fastening of the bottle cap 93 on the bottle body 91, which facilitates the capping mechanism 50 to accurately apply downward pressure to the bottle cap 93, thereby ensuring the accuracy of capping, allowing the capping operation to be continuously performed without stopping each wheel, thereby improving the capping efficiency, and thus greatly improving the work efficiency.

[0053] refer to Figure 1 and Figure 2 In some embodiments, the rotation axes of the first wheel disc 20, the second wheel disc 30 and the third wheel disc 40 are parallel, and the rotation directions of the first wheel disc 20 and the second wheel disc 30 (reference Figure 2 The second wheel disc 30 and the third wheel disc 40 have opposite directions of arrows drawn on the respective wheel discs (refer to Figure 2 The directions of the arrows drawn on the wheels are opposite.

[0054] In this embodiment, the first wheel disc 20 and the second wheel disc 30 in a handover relationship are arranged to rotate in opposite directions, so that the first wheel disc 20 and the second wheel disc 30 can complete the handover at a lower relative speed at the first handover position HO1, thereby improving the stability of the handover process. Similarly, the second wheel disc 30 and the third wheel disc 40 in a handover relationship are arranged to rotate in opposite directions, so that the second wheel disc 30 and the third wheel disc 40 can complete the handover at a lower relative speed at the second handover position HO2, thereby improving the stability of the handover process.

[0055] refer to Figure 2 In some embodiments, the circumferential spacing between adjacent bottle accommodating positions of the first wheel disc 20, the second wheel disc 30 and the third wheel disc 40 are equal, the linear speeds of the first wheel disc 20 and the second wheel disc 30 at the first handover position HO1 are the same, and the linear speeds of the second wheel disc 30 and the third wheel disc 40 at the second handover position HO2 are the same.

[0056] This embodiment ensures that the bottle 91 is delivered at zero relative speed at the delivery position, thereby greatly improving the stability of the delivery process.

[0057] exist Figure 2 In the embodiment, the diameter of the second wheel disc 30 can be larger than the diameter of the first wheel disc 20. By setting the second wheel disc 30 with a larger radius, the second wheel disc 30 with more bottle accommodation positions and a slower rotation speed can be matched with the first wheel disc 20 with fewer bottle accommodation positions and a faster rotation speed, and the first wheel disc 20 with a faster rotation speed can be matched with the bottle conveying mechanism with a faster transmission speed, thereby improving the overall operation efficiency.

[0058] Figure 2 The diameter of the second wheel disc 30 in the embodiment may also be greater than the diameter of the third wheel disc 40. Similarly, the second wheel disc 30 with a larger radius can realize the coordination between the second wheel disc 30 with more bottle accommodation positions and a slower rotation speed and the third wheel disc 40 with fewer bottle accommodation positions and a faster rotation speed, and the third wheel disc 40 with a faster rotation speed can timely transport the closed bottles 92 outward through the bottle conveying mechanism with a faster transmission speed, thereby improving the overall operation efficiency.

[0059] refer to Figure 1 In some embodiments, the third wheel 40 includes a bottle body wheel layer 41 and a bottle cap wheel layer 42 having the same axis, the bottle cap wheel layer 42 is located on the upper side of the bottle body wheel layer 41, a plurality of bottle cap receiving positions of the third wheel 40 are arranged on the bottle cap wheel layer 42, and a plurality of bottle body receiving positions of the third wheel 40 are arranged on the bottle body wheel layer 41. In this embodiment, the bottle cap wheel layer 42 is arranged on the upper side of the bottle body wheel layer 41 to prevent the bottle caps 93 from interfering with the bottles 91 transported by the second wheel 30 when the bottle cap wheel layer 42 rotates.

[0060] exist Figure 1 and Figure 2 In the embodiment, the multiple bottle receiving positions in the bottle wheel layer 41 and the multiple bottle cap receiving positions in the bottle cap wheel layer 42 are aligned one by one along the axis. Thus, by arranging the bottle receiving positions and the bottle cap receiving positions to be aligned one by one along the axis, it is beneficial for the bottle caps 93 to accurately match the uncapped bottles 91 transported by the second wheel 30 at the second handover position HO2, and continue to be transported outward through the third wheel 40 after being capped.

[0061] refer to Figure 2In some embodiments, the capping device further includes: a first bottle conveying mechanism 61 and a spiral bottle separation mechanism 62. The first bottle conveying mechanism 61 is disposed on the frame 10 and intersects / is tangent to the rim of the first wheel disc 20, and is configured to move the bottle 91 toward the direction close to the first wheel disc 20. The spiral bottle separation mechanism 62 is disposed at the intersection / is tangent to the first bottle conveying mechanism 61 and the first wheel disc 20, and is configured to make the bottle 91 on the first bottle conveying mechanism 61 separate from the first bottle conveying mechanism 61, and sequentially enter the plurality of bottle accommodation positions in the first wheel disc 20 according to the intervals between adjacent bottle accommodation positions in the first wheel disc 20.

[0062] In this embodiment, the spiral bottle separation mechanism 62 can accurately deliver the multiple bottles 91 conveyed by the first bottle conveying mechanism 61 to the multiple bottle receiving positions of the first wheel 20 at set intervals. The first bottle conveying mechanism 61 can include but is not limited to a linear bottle conveyor belt. This structure allows the linear bottle conveyor belt to run at a higher speed to improve the overall work efficiency.

[0063] exist Figure 1 In the embodiment, the rotating shaft of the spiral bottle separation mechanism 62 can be parallel to the conveying direction of the first bottle conveying mechanism 61, and the axial spacing between adjacent spiral grooves matches the spacing between adjacent bottle accommodating positions in the first wheel 20 to achieve a more stable and uniform bottle separation effect.

[0064] refer to Figure 2 In some embodiments, the capping device further includes: a second bottle conveying mechanism 63 and a bottle blocking mechanism 64. The second bottle conveying mechanism 63 is disposed on the frame 10 and intersects / is tangent to the third wheel disc 40, and is configured to move the bottle away from the third wheel disc 40. The bottle blocking mechanism 64 is disposed on the side of the second bottle conveying mechanism 63 adjacent to the third wheel disc 40, and is configured to restrict the capped bottle 92 from continuing to move with the third wheel disc 40, so that the capped bottle 92 is separated from the bottle accommodating position of the third wheel disc 40 and enters the second bottle conveying mechanism 63.

[0065] In this embodiment, the capped bottle 92 can be separated from the third wheel 40 by the blocking effect of the bottle blocking mechanism 64, and the bottle blocking mechanism 64 can also guide the movement of the capped bottle 92 on the second bottle conveying mechanism 63. In a specific implementation, if the second bottle conveying mechanism 63 includes a linear bottle conveyor belt, the bottle blocking mechanism 64 can be a guardrail installed on the side of the bottle conveyor belt.
