Description

Technical Field

[0001] The present invention relates to the technical field of food and drug packaging, and particularly relates to a single-dose filling method for a pre-filled and sealed device and a pre-filled and sealed device. Background Art

[0002] The authorized announcement number is CN205313054U, and the name is a pre-filled syringe filling machine, which discloses that after receiving the nest plate by the transfer device, filling and plugging are carried out. The existing series of filling machines generally have compatible filling head numbers of 2 / 5 / 10 heads. In the case of high added value of the liquid medicine, there is a need to be compatible with single-needle filling. Due to the limitation of the package nest plate matrix, if single-needle filling is to be achieved, the span of the horizontal moving X-axis needs to be more than 200, which will cause the equipment to be too wide. And because the equipment usage scenario has characteristic constraints and requires an operating space where hands can be placed on both sides, it will cause the equipment to be too wide to operate, and the filling machine as a whole occupies a large space and the structure is not compact. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a single-dose filling method for a pre-filled and sealed device and a pre-filled and sealed device with good compatibility, low cost and a compact equipment structure.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A single-dose filling method for a pre-filled and sealed device includes the following steps:

[0007] S2. The nest plate loading and unloading device moves the nest plate into the nest box, and the nest box lifting and reversing device lifts the nest box and rotates the nest box 180°;

[0008] S3. The nest plate loading and unloading device moves the nest plate onto the nest plate transfer mechanism;

[0009] S4. The nest plate transfer mechanism moves the nest plate, and the filling and plugging device fills and plugs the remaining containers on the other side of the nest plate row by row and column by column.

[0010] As a further improvement of the above technical solution:

The nest plate loading and unloading device lifts the nest plate in the nest box, the nest plate transfer mechanism moves to below the nest plate loading and unloading device, and the nest plate loading and unloading device descends to place the nest plate into the nest plate transfer mechanism.

[0012] The single-dose potting method further includes step S5. After the potting and plugging are completed, the nest plate transfer mechanism transfers the nest plate to the nest plate loading and unloading device, and the nest plate loading and unloading device unloads the nest plate into the nest box, and the nest box conveying device outputs the nest box.

[0013] A pre-filled syringe device includes a nest box conveying device. A nest plate loading and unloading device and a potting and plugging device are arranged on one side of the nest box conveying device. A nest plate transfer mechanism is arranged below the potting and plugging device. A nest box lifting and reversing device is arranged on the nest box conveying device, and the nest box lifting and reversing device is used for reversing the nest plate in which some containers on one side have been potted during single-dose potting.

[0014] As a further improvement of the above technical solution:

[0015] The nest box conveying device includes a mounting frame, and conveyor belts are arranged on both sides of the mounting frame. The nest box lifting and reversing device is located between the conveyor belts on both sides.

[0034] Embodiment 1

[0035] The following is an embodiment of the pre-filled and sealed device of the present invention. The single-dose filling and sealing method of the pre-filled and sealed device in this embodiment includes the following steps:

[0036] S1. The nest plate transfer mechanism 4 moves the nest plate 8 below the filling and plugging device 3, and the filling and plugging device 3 fills and plugs some of the containers on one side of the nest plate 8 row by row and column by column.

[0037] S2. The nest plate loading and unloading device 2 moves the nest plate 8 into the nest box, and the nest box lifting and reversing device 5 lifts the nest box and rotates the nest box by 180°.

[0038] S3. The nest plate loading and unloading device 2 moves the nest plate to the nest plate transfer mechanism 4.

[0039] S4. The nest plate transfer mechanism 4 moves the nest plate 8, and the filling and plugging device 3 fills and plugs the remaining containers on the other side of the nest plate 8 row by row and column by column.

[0040] For the single-dose filling and sealing method of this pre-filled and sealed device, the nest box lifting and reversing device 5 can lift and rotate the nest box by 180°. Therefore, the moving stroke of the X-axis of the nest plate transfer mechanism 4 during single-dose filling and sealing can be shortened, solving the problem of insufficient operating space caused by the too wide X-axis span. It can be compatible with pre-filled and sealed devices with different numbers of filling heads such as 2 / 5 / 10, improving adaptability, reducing equipment costs, and due to the shortening of the moving stroke, reducing the overall occupied space of the pre-filled and sealed device and making the structure more compact.

[0041] With Figure 5Example of the nest plate for the single-dose encapsulation method of the present invention: The nest plate transfer mechanism 4 moves the nest plate 8 below the filling and plugging device 3. The filling and plugging device 3 fills and plugs 50% of the containers on one side of the nest plate 8 row by row and column by column, that is, containers 1, 2, 3, 4, 5 in each row. After the nest plate 81 is rotated 180°, the other 50% of the containers are filled and plugged, that is, containers 6, 7, 8, 9, 10 in each row. Compared with the traditional single-dose one-way encapsulation, the moving stroke is shortened by 50%. Of course, in other embodiments, the distribution of the encapsulation quantity before and after the rotation direction can be determined according to the actual production requirements.

[0042] Further, in this embodiment, the single-dose encapsulation method further includes step S0. The nest box conveying device 1 inputs the nest box to the nest plate loading and unloading device 2. The nest plate loading and unloading device 2 lifts the nest plate 8 in the nest box. The nest plate transfer mechanism 4 moves below the nest plate loading and unloading device 2, and the nest plate loading and unloading device 2 descends to place the nest plate 8 into the nest plate transfer mechanism 4. Step S0 is a feeding and loading step, and is also applicable to the scenario of multi-dose encapsulation.

[0043] Further, in this embodiment, the single-dose encapsulation method further includes step S5. After the filling and plugging are completed, the nest plate transfer mechanism 4 transfers the nest plate 8 to the nest plate loading and unloading device 2. The nest plate loading and unloading device 2 unloads the nest plate 8 into the nest box, and the nest box conveying device 1 outputs the nest box. Step S5 is a unloading and discharging step, and is also applicable to the scenario of multi-dose encapsulation.

[0044] Embodiment Two

[0045] Figures 1 to 4 An embodiment of the pre-filled encapsulation device of the present invention is shown. The pre-filled encapsulation device of this embodiment includes a nest box conveying device 1. A nest plate loading and unloading device 2 and a filling and plugging device 3 are provided on one side of the nest box conveying device 1. A nest plate transfer mechanism 4 is provided below the filling and plugging device 3. A nest box lifting and reversing device 5 is provided on the nest box conveying device 1. The nest box lifting and reversing device 5 is used to reverse the nest plate 8 that has been filled on one side of some containers during single-dose encapsulation.

[0046] For this pre-filled encapsulation device, the nest box lifting and reversing device 5 can lift and rotate the nest box by 180°. Therefore, the moving stroke of the X-axis of the nest plate transfer mechanism 4 during single-dose encapsulation can be shortened, and the problem of insufficient operating space caused by the too wide X-axis span can be solved. It can be used in scenarios with different numbers of filling heads such as 2 / 5 / 10, and is also applicable to single-dose encapsulation. It has good compatibility, low equipment cost, and due to the shortening of the moving stroke, the overall occupied space of the pre-filled encapsulation device is reduced, and the structure is more compact.

[0047] The single-dose encapsulation method of this pre-filled encapsulation device is the same as that in Embodiment One, and is also applicable to the scenario of multi-dose encapsulation. During multi-dose encapsulation, the nest box lifting and reversing device 5 does not need to act, and it will not hinder other encapsulation scenarios.

[0048] Furthermore, in this embodiment, the nest box conveying device 1 includes a mounting frame 11. Conveyor belts 12 are provided on both sides of the mounting frame 11. The nest box lifting and reversing device 5 is located between the conveyor belts 12 on both sides. The conveyor belts 12 on both sides convey the nest boxes. By arranging the nest box lifting and reversing device 5 between the conveyor belts 12 on both sides, it will not obstruct the conveyor belts 12 on both sides and can be normally applied to the scenario of multi-bottle potting.

[0049] Furthermore, as Figure 3 shown, in this embodiment, fences 13 are provided on the outer sides of the conveyor belts 12 on both sides. The fences 13 play a role in limiting and guiding the nest boxes.

[0050] Furthermore, as Figure 3 shown, in this embodiment, the distance between the fences 13 on both sides is adjustable. It is suitable for the limiting and guiding of nest boxes of different sizes and has high adaptability.

[0051] Furthermore, as Figure 3 shown, in this embodiment, the nest box lifting and reversing device 5 includes a first suction cup 51, a lifting drive 52, and a rotation drive 53. The lifting drive 52 is used to drive the first suction cup 51 to lift, and the rotation drive 53 is used to drive the first suction cup 51 to rotate. When reversing, the lifting drive 52 drives the first suction cup 51 to rise, lifting the nest box on the conveyor belt 12 to a position higher than the fence 13, then the rotation drive 53 drives the first suction cup 51 to rotate 180°, thereby driving the nest box to turn around, and then the lifting drive 52 drives the first suction cup 51 to descend, and the nest box falls onto the conveyor belt 12.

[0052] Furthermore, as Figure 1 shown, in this embodiment, the nest board loading and unloading device 2 includes a loading and unloading robotic arm 21. A second suction cup 22 is provided on the loading and unloading robotic arm 21. The second suction cup 22 can suck and connect to the nest board 8, and the loading and unloading robotic arm 21 drives the second suction cup 22 to move to achieve the automatic loading and unloading of the nest board 8.

[0053] Furthermore, as Figure 1 and Figure 2 shown, in this embodiment, the pre-potting equipment further includes a filling pump device 6 and a plug sorting device 7. The filling pump device 6, the plug sorting device 7, and the nest board transfer mechanism 4 are respectively located on different sides of the filling and plugging device 3. The structure is compact.
