Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical packaging methods, and more particularly to a method of inserting packaging inserts. Background Technology

[0002] The pre-filled honeycomb platform moves the honeycomb tray between multiple stations. During stoppering, the stopper rod and stopper sleeve need to be inserted into the bottle body. The minimum gap between the stopper sleeve and the bottle body is less than 0.3mm, and the peak velocity of the stopper descent is close to 1m / s. Due to process requirements, the stoppering process may need to be paused at any time, or the honeycomb platform may need to exit the stoppering station and enter a non-stoppering station (including weighing station, loading / unloading station, or entering a follow-up process or rejecting process, etc.). This results in a discontinuity between the honeycomb platform movement and the stoppering process, requiring flexible and reliable position control via the platform's servo drive. A common approach is to determine the platform's position before performing the stoppering action, leading to reduced stoppering efficiency.

[0003] The earlier application CN112794257A discloses a system and method for container filling and capping. After the filling device completes filling two or more rows of containers, a second capping device caps the containers in the previous row, while a first capping device caps the containers in the next row (both the first and second capping devices are equipped with capping sleeves below them), which is beneficial to improving the system's production efficiency. However, the capping process still requires waiting for the conveying device to transport the containers into place before starting. Furthermore, the capping process requires waiting for the rubber stopper transfer device to move into place so that the rubber stoppers in the first and second rubber stopper positioning channels are transferred to the area below the first and second capping devices (specifically, below the capping sleeves), and then the first and second capping devices press the rubber stoppers below into the containers. This has the aforementioned drawback that leads to reduced capping efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a method for cutting in line that can reduce waiting time and improve cutting efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A method for inserting filler, including a filler insertion process:

[0007] The conveying component moves the container toward the stoppering station, while the stoppering component descends to press the stopper in the stopper transfer component into the stoppering guide component;

[0008] After the rubber stopper is detached from the rubber stopper transfer component, the rubber stopper transfer component moves towards the stopper removal station. After the rubber stopper transfer component reaches the stopper removal station, the stopper pushing component pushes the rubber stopper into the rubber stopper transfer component to complete the stopper removal. Then the rubber stopper transfer component moves towards the stopper insertion station to reset.

[0009] After the conveying component moves to the plugging station, the plugging guide component and the plugging component descend to the set position, the plugging guide component rises until it resets, and after the plugging guide component separates from the rubber plug, the plugging component rises, and the rubber plug transfer component avoids the rising plugging component and then completes the reset.

[0010] The insert component rises to the set position and then descends to the initial position.

[0011] As a further improvement to the above technical solution: when the stopper is in its initial position, its lower end is located below the intersection of the movement trajectories of the stopper and the rubber stopper transfer component.

[0012] As a further improvement to the above technical solution: when the stopper guide component and the stopper component descend, the lower end of the stopper guide component enters the container first.

[0013] As a further improvement to the above technical solution, the specific steps are as follows:

[0014] S1. Loading process: Load the container at the loading / unloading station to the conveying component. If a plugging process is required, execute step S2. If other processes are required, execute step S4.

[0015] S2, Insertion process;

[0016] S3. If the inserting process is to continue, proceed to step S2; if other processes are to be performed, proceed to step S4; if the unloading process is to be performed, proceed to step S5.

[0017] S4. The conveying component moves the container to other workstations to complete other processes. If a plugging process is required, execute step S3. If a material unloading process is required, execute step S5.

[0018] S5, Unloading process: The conveying components move the container to the unloading / loading station.

[0019] As a further improvement to the above technical solution: the rubber stopper transfer component is a swing structure, and the swing axis of the rubber stopper transfer component is arranged horizontally and located between the stopper adding station and the stopper taking station.

[0020] As a further improvement to the above technical solution: the conveying component is a honeycomb platform, which is located on the conveying track.

[0021] As a further improvement to the above technical solution: the loading and unloading station is equipped with a loading and unloading robot, and the loading and unloading robot is equipped with multiple vacuum suction cups for gripping honeycomb trays.

[0022] Compared with the prior art, the advantages of the present invention are as follows: In the stoppering method disclosed in the present invention, when the conveying component moves the container to the stoppering station, the stoppering component begins to descend and press the rubber stopper in the rubber stopper transfer component into the stoppering guide component. After the rubber stopper is detached from the rubber stopper transfer component, the rubber stopper transfer component begins to move to the stopper removal station to remove the rubber stopper. After removal, it continues to move to the stoppering station to reset. At the same time, after the conveying component is in place, the stoppering guide component and the stoppering component descend and cooperate with each other to complete the stoppering action. The rubber stopper transfer component avoids the rising stoppering component and completes the reset, which can greatly reduce the waiting time, improve the stoppering efficiency, and avoid interference between the components during the operation. During the stoppering process, the stoppering guide component rises first, and the stoppering component remains stationary against the rubber stopper, so that the stoppering guide component can smoothly detach from the rubber stopper and reduce the descent stroke of the stoppering component. The process is reasonable and effective.

[0023] Furthermore, when the plugging component is in its initial position, it is close to the rubber plug transfer component, which helps to improve the efficiency of pressing the rubber plug into the plugging guide component. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Figure 2 to Figure 3 An embodiment of the present invention is shown, wherein the method for inserting filler ...

[0034] Specifically, such as Figure 2a As shown, the conveying component 2 moves the container toward the stoppering station 3, while the stoppering component 4 (e.g., a stoppering rod) descends to press the rubber stopper 9 in the rubber stopper transfer component 5 into the stoppering guide component 6 (e.g., a stoppering sleeve).

[0035] Specifically, such as Figures 2b to 2d As shown, after the rubber stopper 9 is separated from the rubber stopper transfer component 5, the rubber stopper transfer component 5 moves to the stopper removal station 7. After the rubber stopper transfer component 5 reaches the stopper removal station 7, the top stopper component 8 pushes the rubber stopper into the rubber stopper transfer component 5 to complete the stopper removal. Then the rubber stopper transfer component 5 moves to the stopper insertion station 3 to reset.

[0036] After the conveying component 2 moves to the inserting station 3, the inserting guide component 6 follows the inserting component 4 and descends to the set position, as follows: Figures 2e to 2f As shown and Figure 3 As shown, the plug guide component 6 rises until it is reset. After the plug guide component 6 separates from the rubber plug 9, the plug component 4 rises. The rubber plug transfer component 5 avoids the rising plug component 4 and then completes the reset.

[0037] Specifically, such as Figure 2g As shown, the insert component 4 rises to the set position and then falls back to the initial position.

[0038] In this embodiment, when the conveying component 2 moves the container towards the stoppering station 3, the stoppering component 4 begins to descend, pressing the rubber stopper 9 from the rubber stopper transfer component 5 into the stoppering guide component 6. After the rubber stopper 9 detaches from the rubber stopper transfer component 5, the rubber stopper transfer component 5 begins to move towards the stopper removal station 7 to remove the rubber stopper. After removal, it continues to move towards the stoppering station 3 to reset. At the same time, after the conveying component 2 moves the container into position, the stoppering guide component 6 and the stoppering component 4 descend and cooperate to complete the stoppering action. The rubber stopper transfer component 5 avoids the rising stoppering component 4 and then resets, which can greatly reduce waiting time, improve stoppering efficiency, and avoid interference between components during operation. During the stoppering process, the stoppering guide component 6 rises first, while the stoppering component 4 remains stationary against the rubber stopper 9, allowing the stoppering guide component 6 to smoothly detach from the rubber stopper 9 and reducing the descent stroke of the stoppering component 4 (compared to directly pressing the rubber stopper 9 from the stoppering guide component 6 into the container, the stroke of the stoppering component 4 is reduced). The process is reasonable and effective.

[0039] Furthermore, in this embodiment, when the stopper 4 is in its initial position, its lower end is located below the intersection of the movement trajectories of the stopper 4 and the rubber stopper transfer component 5. See 2a for details. Figure 2f and Figure 2g The movement trajectory of the stopper insertion component 4 is a vertical straight line, while the movement trajectory of the rubber stopper transfer component 5 is an arc in a vertical plane. The intersection point of the two is... Figure 2f Point P in the diagram. When the stopper 4 is in its initial position, it is close to the stopper transfer component 5, which helps to improve the efficiency of pressing the stopper 9 into the stopper guide component 6.

[0040] Furthermore, in this embodiment, when the stopper guide component 6 and the stopper component 4 descend, the lower end of the stopper guide component 6 enters the container first. This first entry of the lower end of the stopper guide component 6 into the container facilitates the use of the gap between the outer wall of the stopper guide component 6 and the inner wall of the container for venting, making the stoppering process smoother.

[0041] As a preferred embodiment, the specific steps are as follows:

[0042] S1. Loading process: Load the container at loading / unloading station 1 to the conveying component 2. If a plugging process is required, execute step S2. If other processes are required, execute step S4.

[0043] S2, Insertion process;

[0044] S3. If the inserting process is to continue, proceed to step S2; if other processes are to be performed, proceed to step S4; if the unloading process is to be performed, proceed to step S5.

[0045] S4. Conveying component 2 moves the container to other workstations to complete other processes. If a plugging process is required, execute step S3. If a material unloading process is required, execute step S5.

[0046] S5, unloading process: the conveyor component 2 moves the container to the unloading / loading station 1.

[0047] In a preferred embodiment, the rubber stopper transfer component 5 is a swing structure. The swing axis of the rubber stopper transfer component 5 is arranged horizontally and located between the stopper insertion station 3 and the stopper removal station 7, which facilitates the rubber stopper transfer component 5 to remove the rubber stopper 9 from the stopper removal station 7 and transfer the rubber stopper 9 to the stopper insertion guide component 6 at the stopper insertion station 3. The structure is simple, reliable, and has high operating efficiency. Of course, in other embodiments, other methods can also be used to transfer the rubber stopper 9.

[0048] In a preferred embodiment, the conveying component 2 is a honeycomb platform, which facilitates the conveying of containers such as pre-filled needles that cannot be directly conveyed using a mesh belt. The honeycomb platform is located on the conveying track 21. Of course, in other embodiments, the containers can also be conveyed using other methods.

[0049] In a preferred embodiment, the loading / unloading station 1 is equipped with a loading / unloading robot 11, which has multiple vacuum suction cups 12 for gripping honeycomb trays. By controlling the vacuum on / off of the vacuum suction cups 12, the honeycomb trays can be easily gripped or placed down, thereby enabling the transfer of the honeycomb trays between different processes. Of course, in other embodiments, other methods can also be used to transfer the honeycomb trays.

Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
