Abstract
Description
Technical Field
[0001] This invention relates to the field of food and pharmaceutical packaging machinery and equipment, and in particular to a powder / liquid pre-filling system and method. Background Technology
[0002] Currently, most nested pre-filled needle filling and stoppering machines are generally used for filling liquid medicines and are rarely used for powder filling. The reasons are as follows: First, powder filling is prone to dust generation, which pollutes the filling environment and affects the filling quality; Second, the packaging materials of nested pre-filled needles are limited by the packaging material matrix, and the spacing between them is very small. When filling powder, there is a high risk that the powder will spill into the adjacent pre-filled needles, affecting the filling accuracy. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a powder / liquid pre-filling system and method that improves filling accuracy, overall system utilization and saves production costs.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A powder / liquid pre-filling system includes a packaging material conveying device, a pick-and-place device, a filling bracket, a sealing device, a liquid supply device mounting base, a powder supply device mounting base, and a baffle mounting base. The liquid supply device mounting base may be equipped with a liquid supply component, and the powder supply device mounting base may be equipped with a powder supply component. The filling bracket may be equipped with a filling needle that cooperates with the liquid supply component or the powder supply component for filling the packaging material. The baffle mounting base may be equipped with a powder baffle plate with powder suction holes. The powder baffle plate is used to block part of the packaging material in the packaging material conveying device. The filling bracket can rotate to the powder supply component to pick up powder and fill the packaging material exposed outside the powder baffle plate that is not filled. The sealing device is used to plug the packaging material on the packaging material conveying device, and the pick-and-place device is used to pick up and place packaging material on the packaging material conveying device.
[0006] As a further improvement to the above technical solution:
[0007] The filling support can be raised and lowered.
[0008] The powder baffle plate has a row of clearance grooves on the side facing the sealing device that correspond to each filling needle.
[0009] The inner wall of the clearance groove is provided with a first powder suction hole.
[0010] The top surface of the powder baffle plate is provided with multiple rows of second powder suction holes, and each row of second powder suction holes is distributed along the direction of each filling needle.
[0011] The powder baffle is connected to a suction mechanism, and both the first and second powder suction holes are connected to the suction mechanism.
[0012] The packaging material conveying device includes a pallet conveying mechanism and a pallet for holding packaging materials, with the powder baffle plate located above the pallet conveying mechanism.
[0013] The pick-and-place device is equipped with a nest box conveying device on one side, and the pick-and-place device is used to transfer packaging materials between the nest box conveying device and the packaging material conveying device.
[0014] The nest box conveying device is equipped with a detection mechanism to detect whether the inner lining paper and the lid paper of the nest box have been removed.
[0015] A powder / liquid pre-filling method, using the aforementioned powder / liquid pre-filling system, wherein the powder supply device mounting base is provided with a powder supply assembly, the filling bracket is provided with a filling needle that cooperates with the powder supply assembly for filling packaging material, and the baffle mounting base is provided with a powder baffle plate, the method comprising the following steps:
[0016] S1. Placing Packaging Materials: The pick-and-place device places the packaging materials onto the packaging material conveying device;
[0017] S2, Powder filling and plugging: The packaging material conveying device reciprocates between the filling support and the sealing device. After the filling support fills the unfilled packaging material that is exposed outside the powder baffle, the packaging material conveying device then conveys the packaging material to the sealing device for plugging.
[0018] S3. Retrieving Packaging Materials: After the packaging materials are filled and plugged, they are transported to the pick-and-place device via the packaging material conveying device and then retrieved by the pick-and-place device.
[0019] Compared with the prior art, the advantages of the present invention are as follows:
[0020] This invention relates to a powder / liquid pre-filling system. The pre-filling process is as follows: First, a pick-and-place device places rows of packaging materials onto a packaging material conveying device. Second, the packaging material conveying device reciprocates the rows of packaging materials to a powder baffle and a sealing device, ensuring that each row of packaging materials is conveyed until it protrudes beyond the powder baffle (the side of the powder baffle facing the sealing device). After filling through a filling bracket, the materials are then conveyed to the sealing device for capping. Finally, after the rows of packaging materials are filled and capped, they are conveyed to the pick-and-place device for removal. On one hand, the packaging materials can be filled row by row. During filling (or filling), the powder baffle blocks the subsequent rows of packaging materials, preventing powder from seeping into the later rows of packaging materials that are not yet ready for filling, thus improving filling accuracy. Furthermore, the system allows for row-by-row filling and capping, ensuring that when the later rows of packaging materials are being filled, the previous rows are already capped, and although they protrude beyond the powder baffle, their interiors are not affected by powder seepage, protecting filling accuracy. On the other hand, the filling bracket can selectively cooperate with either the liquid supply device mounting base or the powder supply device mounting base, allowing liquid filling and powder filling to be carried out separately. This not only meets the filling requirements of powder and liquid, but also avoids mutual interference between powder and liquid filling. At the same time, it improves the utilization rate of the entire system and saves production costs.
[0021] The powder / liquid pre-filling method of this invention has two advantages. First, the packaging materials can be filled row by row. During filling (or filling), a powder baffle blocks the subsequent rows of packaging materials, preventing powder from seeping into the later rows of packaging materials that are not yet ready for filling, thus improving filling accuracy. Furthermore, the method allows for row-by-row filling and plugging, ensuring that while the previous rows of packaging materials are being filled, even if they are exposed outside the powder baffle, their interiors are not affected by powder seepage, protecting filling accuracy. Second, the filling bracket can selectively cooperate with either the liquid supply device mounting base or the powder supply device mounting base, allowing liquid and powder filling to be performed separately. This satisfies the filling requirements of both powder and liquid while avoiding mutual interference between them, thereby improving the overall system utilization and saving production costs.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0032] Example 1:
[0033] Figures 1 to 4 This invention illustrates an embodiment of the powder / liquid pre-filling system. The system includes a packaging material conveying device 1, a pick-and-place device 2, a filling bracket 3, a sealing device 5, a liquid supply device mounting base 4, a powder supply device mounting base 7, and a baffle mounting base. The liquid supply device mounting base 4 may be equipped with a liquid supply component, and the powder supply device mounting base 7 may be equipped with a powder supply component. The filling bracket 3 may be equipped with a filling needle 32 that cooperates with the liquid supply component or the powder supply component for filling the packaging material. The baffle mounting base may be equipped with a powder baffle plate 6, which has a powder suction hole. The powder baffle plate 6 is used to block part of the packaging material in the packaging material conveying device 1. The filling bracket 3 can rotate to the powder supply component to pick up powder and fill the unfilled packaging material 8 exposed outside the powder baffle plate 6. The sealing device 5 is used to plug the packaging material 8 on the packaging material conveying device 1, and the pick-and-place device 2 is used to pick up and place the packaging material 8 on the packaging material conveying device 1.
[0034] The liquid supply device mounting base 4 is used to install the liquid supply assembly, which includes a liquid storage container, a delivery pump, etc. The powder supply device mounting base 7 is used to install the powder supply assembly, which includes a powder hopper, a vibrating feeder, a powder tray, etc. When the pre-filling system is used for liquid filling, a liquid storage container will be installed on the liquid supply device mounting base 4, and the liquid storage container will be connected to the delivery pump by a pipeline. The pipeline will also be connected to the filling needle 32 on the filling bracket 3. During the liquid filling process, the powder supply device mounting base 7 will not have the powder supply assembly installed, or will only have a partial powder supply assembly installed. Powder assembly; When the pre-filling system is used for powder filling, the powder supply device mounting base 7 will be equipped with a powder bucket, vibrating feeder, powder tray, etc. The filling needle on the filling bracket 3 will rotate to the powder tray to pick up powder, which is the existing airflow dispensing. During the powder filling process, the liquid supply device mounting base 4 will not be equipped with a liquid supply assembly, or will be equipped with a partial liquid supply assembly. During the powder filling process, the baffle mounting base will be equipped with a powder baffle 6. During the powder filling or liquid filling process, the filling needle 32 will also be replaced with a filling needle suitable for liquid filling or powder filling.
[0035] The powder baffle 6 can be set on the movement path of the filling support 3 to pick up powder, or it can be set between the filling support 3 and the sealing device 5. The powder baffle 6 can be provided with a relief groove 61 or a relief hole through which the filling needle passes.
[0036] Powder / liquid pre-filling process: First, the pick-and-place device 2 places the packaging materials 8 in rows on the packaging material conveying device 1; second, the packaging material conveying device 1 reciprocates between the filling support 3 and the sealing device 5, so that the packaging materials 8 are conveyed row by row to the outside of the powder baffle 6 (the outside of the powder baffle 6 facing the sealing device 5), filled through the filling support 3, and then conveyed to the sealing device 5 for capping; finally, after the rows of packaging materials 8 are filled and capped, they are conveyed to the pick-and-place device 2 through the packaging material conveying device 1 and removed by the pick-and-place device 2. On the one hand, the packaging materials 8 can be filled row by row. When filling powder, the powder baffle 6 blocks the unfilled packaging materials 8, preventing powder from spilling into the unfilled packaging materials 8, thus improving filling accuracy. On the other hand, it can fill and cap row by row. In this way, when the later rows of packaging materials 8 are filled, the previous rows of packaging materials 8 have already been capped. Although they are exposed outside the powder baffle 6, their interiors will not be affected by powder spilling in, thus protecting filling accuracy. On the other hand, the filling bracket 3 can selectively cooperate with the liquid supply device mounting base 4 or the powder supply device mounting base 7 to separate the liquid filling and powder filling. This can not only meet the filling requirements of powder or liquid, but also avoid mutual interference between the filling of powder or liquid. At the same time, it improves the utilization rate of the entire system and saves production costs.
[0037] Furthermore, in this embodiment, the filling bracket 3 can be raised and lowered, thereby driving the filling needle to rise and fall.
[0038] Furthermore, in this embodiment, the filling support 3 includes a rotating frame 31 rotatably mounted on one side of the powder baffle plate 6 and a row of filling needles 32 mounted on the rotating frame 31, with each filling needle 32 spaced apart along the radial direction of the rotating frame 31. During filling, each filling needle 32 is aligned with the packaging material below to fill the powder. During powder filling, the rotating frame 31 first rotates the filling needle 32 to the powder supply device mounting seat 7 to pick up the powder, and then rotates back to the powder baffle plate 6 to align with the corresponding row of packaging materials 8 exposed outside the powder baffle plate 6 for powder filling.
[0039] Furthermore, the rotating frame 31 can also move up and down to meet the filling requirements of the inserted packaging material 8.
[0040] Furthermore, in this embodiment, the powder baffle 6 is provided with a row of clearance grooves 61 corresponding to each filling needle 32 on the side facing the sealing device 5. On the one hand, the clearance grooves 61 allow the filling needles 32 to pass through to achieve filling; on the other hand, the powder baffle 6 between adjacent clearance grooves 61 can block the even-numbered or odd-numbered packaging materials 8 in the filling row during filling, such as filling the even-numbered packaging materials 8 first and then filling the odd-numbered packaging materials 8 (at this time, a staggered mechanism is generally set at the filling station to allow the packaging materials 8 to be laterally staggered to meet the requirement of separate filling of odd and even-numbered packaging materials 8), avoiding mutual interference when filling adjacent packaging materials 8 with small intervals.
[0041] Furthermore, such as Figure 2 As shown, in this embodiment, a first powder suction hole 611 is provided on the inner wall of the clearance groove 61. This hole is used to suction away the powder that falls off when the filling needle 32 moves vertically relative to the clearance groove 61, preventing the powder from affecting the powder in the odd and even positions of the packaging material 8 in the filling row.
[0042] Furthermore, in this embodiment, the top surface of the powder baffle plate 6 is provided with multiple rows of second powder suction holes 612, and each row of second powder suction holes 612 is distributed along the direction of each filling needle 32. The second powder suction holes 612 are used to suck up the powder that falls off during the powder feeding movement (arc movement) of the filling needle 32.
[0043] Furthermore, in this embodiment, the powder baffle 6 is connected to a suction mechanism 62, and both the first powder suction hole 611 and the second powder suction hole 612 are connected to the suction mechanism 62. The suction mechanism 62 enables the first powder suction hole 611 and the second powder suction hole 612 to have suction force to draw powder.
[0044] Furthermore, in this embodiment, the packaging material conveying device 1 includes a pallet conveying mechanism 11 and a pallet 12 for holding the packaging materials 8, with a powder baffle 6 disposed above the pallet conveying mechanism 11. The pallet conveying mechanism 11 is used to convey the pallet 12.
[0045] Furthermore, in this embodiment, a nest box conveying device 9 is provided on one side of the picking and placing device 2. The picking and placing device 2 is used to transfer the packaging material 8 between the nest box conveying device 9 and the packaging material conveying device 1. The packaging material 8 is a container such as a vial, a cartridge bottle, or a pre-filled syringe. Multiple containers are usually fixed in the nest box by a nest board. When the picking and placing device 2 takes out the containers, it can take out the containers directly or take out the nest board. When taking out the nest board, the containers are taken out together.
[0046] Furthermore, in this embodiment, the nest box conveying device 9 is equipped with a detection mechanism 91, which is used to detect whether the inner lining paper and the lid paper of the nest box have been removed.
[0047] Furthermore, the pick-and-place device 2, the filling support 3, and the sealing device 5 are arranged sequentially along the packaging material conveying device 1 to facilitate the overall operation of the system.
[0048] Furthermore, the filling process (the filling support 3 and the liquid supply assembly work together):
[0049] ① Feeding: The nest box conveyor 9 transports the nest boxes to the testing institution 91;
[0050] ② Final inspection of the inner lining: The nest box stops at the inspection agency 91, and the four corners are checked to see if the inner lining paper or the box cover paper has not been completely removed;
[0051] ③ Loading: The nest box conveying device 9 transports the nest box to the position of the picking and placing device 2. The picking and placing device 2 uses a suction cup to lift the nest board. The pallet conveying mechanism 11 moves the pallet 12 to the position of the picking and placing device 2. The picking and placing device 2 picks up the packaging material 8 inside the nest box and places it onto the pallet 12.
[0052] ④ Filling and capping: The pallet conveyor 11 transports the packaging material 8 to the filling station and the capping station, and fills and caps it row by row through the filling bracket 3 of the filling station and the sealing device 5 of the capping station.
[0053] ⑤ Unloading: After filling and plugging are completed, the pallet conveyor 11 transports the packaging material 8 to the position of the pick-and-place device 2. The pick-and-place device 2 takes out the packaging material and lowers it back into the nest box.
[0054] ⑥ Discharge: The nest box conveyor 9 transports the nest boxes for discharge;
[0055] Furthermore, the powder filling process (the filling support 3 and the powder supply assembly work together):
[0056] ① Feeding: The nest box conveyor 9 transports the nest boxes to the testing institution 91;
[0057] ② Final inspection of the inner lining: The nest box stops at the inspection agency 91, and the four corners are checked to see if the inner lining paper or the box cover paper has not been completely removed;
[0058] ③ Loading: The nest box conveying device 9 transports the nest box to the position of the picking and placing device 2. The picking and placing device 2 uses a suction cup to lift the nest board. The pallet conveying mechanism 11 moves the pallet 12 to the position of the picking and placing device 2. The picking and placing device 2 picks up the packaging material 8 inside the nest box and places it onto the pallet 12.
[0059] ④ Filling: The pallet conveyor 11 transports the packaging material 8 to below the powder baffle 6. After the filling bracket 3 takes powder from the powder supply component, it rotates to directly above the row of packaging materials 8 that are exposed outside the powder baffle 6, and then descends to insert into the packaging material 8 to fill the powder into the packaging material 8.
[0060] ⑤ Stuffing: During the time when the filling bracket 3 returns to the powder supply component to pick up powder, the pallet conveying mechanism 11 transports the filled packaging material 8 to the sealing device 5 and stuffs the packaging material 8 that has just been filled with powder.
[0061] ⑥ Unloading: After filling and plugging are completed, the pallet conveying mechanism 11 transports the packaging material 8 to the position of the pick-and-place device 2. The pick-and-place device 2 uses a suction cup to remove the packaging material, lowers it back into the nest box, and the nest box conveying device 9 transports the nest box out.
[0062] During the powder filling process, powder filling will only start when there is only one open packaging material 8 in the entire equipment and this open packaging material 8 is below the powder baffle plate 6. This effectively ensures that the powder emitted during the powder filling process does not affect the open packaging material 8 (the packaging material 8 after being plugged and sealed is not affected by this risk. Therefore, during the unloading and transfer of the plugged packaging material 8, waiting time can be disregarded to ensure production capacity).
[0063] During the powder filling process, the filling needle 32 picks up powder from the powder supply assembly and rotates along the swing trajectory of the rotating frame 31 to fill the packaging material 8 above the row of packaging materials 8 exposed outside the powder baffle plate 6. After filling, the filling needle 32 stops in the clearance groove 61 and the powder remaining on the filling needle 32 is blown away by the first powder suction hole 611. The powder baffle plate 6 prevents powder from falling into other unfilled packaging materials 8. The second powder suction hole 612 is set along the swing trajectory of the filling needle 32. When the filling needle 32 sweeps over the powder baffle plate 6, the powder that falls will be sucked away by the second powder suction hole 612.
[0064] Furthermore, the dust baffle 6 is located 2mm directly above the packaging material 8. The dust baffle 6 is equipped with a vacuum cleaner pipe inside to provide suction, which draws the powder from the dust suction hole into the dust baffle 6, preventing the powder from overflowing and aggravating pollution.
[0065] Example 2:
[0066] A filling and capping method is performed using the powder / liquid pre-filling system of Example 1. The powder supply device mounting base 7 is equipped with a powder supply component, the filling bracket 3 is equipped with a filling needle 32 that cooperates with the powder supply component for filling the packaging material, and the baffle mounting base is equipped with a powder baffle 6. The method includes the following steps:
[0067] S1. Placing Packaging Material 8: The pick-and-place device 2 places the packaging material 8 onto the packaging material conveying device 1;
[0068] S2, Powder filling and plugging: The packaging material conveying device 1 reciprocates between the filling support 3 and the sealing device 5. After the filling support 3 fills the unfilled packaging material 8 that is exposed outside the powder baffle 6, the packaging material conveying device 1 then conveys the packaging material 8 to the sealing device 5 for plugging.
[0069] S3. Take out packaging material 8: After the packaging material 8 is filled and plugged, it is transported to the take-out device 2 through the packaging material conveying device 1 and taken out by the take-out device 2.
[0070] This filling and capping method has two advantages. First, the packaging materials 8 can be filled row by row. During filling (or filling), the powder baffle 6 blocks the subsequent rows of packaging materials 8, preventing powder from spilling into the later rows of packaging materials 8 that are not yet ready for filling, thus improving filling accuracy. Furthermore, the method allows for row-by-row filling and capping, ensuring that while the previous rows of packaging materials 8 are being filled, they are already capped and, although exposed outside the powder baffle 6, their interiors are not affected by powder spillage, protecting filling accuracy. Second, the filling bracket 3 can selectively cooperate with either the liquid supply device mounting base 4 or the powder supply device mounting base 7, allowing liquid and powder filling to be performed separately. This satisfies the filling requirements of both powder and liquid while avoiding mutual interference between them. Simultaneously, it improves the overall system utilization and saves production costs.
[0071] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. 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 modifications 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.
