Description

Technical Field

[0001] This invention relates to the field of cartridge bottle nesting technology, and particularly to a material bottle nesting process and apparatus. Background Technology

[0002] A cartridge vial is a container similar to a syringe without a plunger. Its design is equivalent to a bottle without a bottom. The front is equipped with a rubber-sealed injection needle, the mouth is sealed with a rubber stopper and an aluminum cap, and the tail is sealed with a rubber piston. This design allows cartridge vials to be used in reusable cartridge injection holders or injection pens. During use, the liquid medication will not come into contact with any part of the syringe, thus ensuring the purity and safety of the medication.

[0003] In the production of cartridge bottles, in order to facilitate subsequent packaging, transportation and storage, cartridge bottles need to be placed into nesting trays. This operation is called cartridge bottle nesting process. In the existing cartridge bottle nesting process, the cleaning and pressure difference control of the interface area are difficult during the transfer of cartridge bottles between different workshops. Not only is cross-contamination easy to occur between different workshops, but the working pressure difference will also be greatly affected, causing many inconveniences to cartridge bottle production. Summary of the Invention

[0004] The purpose of this invention is to provide a material bottle nesting process and apparatus to solve the technical problems in the prior art where the cleaning and pressure differential control of the interface area between different workshops is difficult during the nesting process of cartridge bottles, which not only easily leads to cross-contamination, but also significantly affects the working pressure differential.

[0005] To achieve the above objectives, this invention proposes a material bottle nesting process, comprising the following steps: The cartridge bottles are transferred from the filling room to the first mouse hole area, and then from the first mouse hole area to the buffer room. During the transfer, the first sealing door and the second sealing door on both sides of the first mouse hole area are opened and closed in sequence. The cartridge bottle is transferred from the buffer room to the second mouse hole area, and then from the second mouse hole area to the nesting room. During the transfer, the third and fourth sealing doors on both sides of the second mouse hole area are opened and closed in sequence.

[0006] Preferably, the cartridge bottle is transferred from the filling room to the first mouse hole area, and then from the first mouse hole area to the buffer room. During the transfer process, the first sealing door and the second sealing door on both sides of the first mouse hole area are opened and closed in sequence. Specifically, the first sealing door opens, the second sealing door closes, the first robotic arm transfers the cartridge bottle from the filling room to the first mouse hole area, and then the first sealing door closes, the second sealing door opens, and the second robotic arm transfers the cartridge bottle to the buffer mechanism in the buffer room for transport.

[0007] Preferably, the second robotic arm transfers the cartridge bottle to the buffer mechanism in the buffer room for transport as follows: a conveyor belt drives the buffer plate for transport, and the cartridge bottle is temporarily stored in a slot on the buffer plate. During transport, a detection unit detects whether the cartridge bottle in the slot is in place.

[0008] Preferably, the cartridge bottle is transferred from the buffer room to the second mouse hole area, and then from the second mouse hole area to the nesting room. During the transfer, the third and fourth sealing doors on both sides of the second mouse hole area are opened and closed in sequence. Specifically, the third sealing door opens, the fourth sealing door closes, the third robotic arm transfers the cartridge bottle from the buffer room to the second mouse hole area, and then the third sealing door closes, the fourth sealing door opens, and the fourth robotic arm transfers the cartridge bottle to the feeding conveyor belt in the nesting room for transport.

[0009] Preferably, the method includes the following steps: the nesting board is transported by a first conveyor belt to a first lifting mechanism, and then transferred by a first flipping mechanism to an in-nest conveyor belt; a limiting mechanism limits the nesting board; a fifth robotic arm transfers the cartridge bottle on the feeding conveyor belt to the nesting board; after the cartridge bottle has been placed into the nest, the in-nest conveyor belt transports the fully loaded nesting board to a second flipping mechanism; the second flipping mechanism transfers the fully loaded nesting board to a second lifting mechanism; and the second lifting mechanism then transfers the fully loaded nesting board to a second conveyor belt.

[0010] Preferably, the limiting mechanism limits the nest board by: when the nest board is transported to the predetermined position, the first power component drives the limiting frame to descend, the limiting frame limits the outer periphery of the nest board, and the toothed plate frame limits the middle part of the nest board.

[0011] Preferably, the method includes the following steps: when multiple sets of nesting boards stacked together are transferred from the first lifting mechanism to the first flipping mechanism, the separation mechanism separates two adjacent sets of nesting boards, specifically: the second power member drives the third power member to move, adjusting the height of the insert plate to be between two adjacent sets of nesting boards, and the third power member drives the insert plate to insert into the gap between two adjacent sets of nesting boards.

[0012] In another aspect of the present invention, a material bottle nesting device is provided, which is applied to the aforementioned material bottle nesting process, including: a filling room, a nesting room and a buffer room; The buffer room is located between the filling room and the nesting room. The cartridge bottles are filled in the filling room, and the filled cartridge bottles are assembled with the nest tray in the nesting room. The buffer room is used to separate the filling room from the nesting room. The filling room and the buffer room are provided with a first rat hole area, and a first sealing door and a second sealing door are movably installed on both sides of the first rat hole area. The buffer room and the nesting room are provided with a second rat hole area, and a third sealing door and a fourth sealing door are movably installed on both sides of the second rat hole area.

[0013] Preferably, it includes a buffer mechanism, a feeding conveyor belt, a first conveyor belt, a first lifting mechanism, a first turning mechanism, an inlet conveyor belt, a limiting mechanism, a second turning mechanism, a second lifting mechanism, and a second conveyor belt; The buffer mechanism is located in the buffer room and includes a buffer plate and a detection unit. The buffer plate is used to transport the cartridge bottle, and the buffer plate has slots for temporarily storing the cartridge bottle. The two sets of detection units are respectively disposed at both ends of the buffer mechanism, and are used to detect whether the cartridge bottle is present in the slot; The feeding conveyor belt is set in the inlet chamber and includes a conveyor belt and a clamp. The clamp is set on the conveyor belt and is used to transport the filled cartridge bottles. The first conveyor belt, the first lifting mechanism, the first turning mechanism, the nesting conveyor belt, the second turning mechanism, the second lifting mechanism, and the second conveyor belt are arranged in sequence to transport the nest tray and the filled cartridge bottle; The limiting mechanism includes a first power component, a limiting frame, and a toothed plate frame. The limiting frame is disposed on the toothed plate frame, and the toothed plate frame is mounted inside the limiting frame.

[0014] Preferably, the mechanism includes a separation mechanism disposed on both sides of the first lifting mechanism, comprising a second power member, a third power member, and a insert plate, wherein the third power member is disposed at the movable end of the second power member, and the insert plate is disposed at the movable end of the third power member.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: by sequentially opening a first mouse hole area and a second mouse hole area between the filling room, the buffer room and the nesting room, and using the mouse hole structure as a narrow passage, the area of ​​the connecting passage between the filling room, the buffer room and the nesting room is minimized, reducing the risk of pollutants spreading with the airflow. Furthermore, the first mouse hole area and the second mouse hole area are respectively equipped with sealing doors on both sides for selective sealing, which can ensure that the filling room, the buffer room and the nesting room will never be connected during the transfer of cartridge bottles. This prevents the airflow between areas with different cleanliness and pressure levels on both sides of the first mouse hole area or the second mouse hole area from directly penetrating, thereby maintaining a stable pressure gradient between the areas and providing many conveniences for the production of cartridge bottles.

Detailed Implementation

[0018] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0019] Example 1

[0020] like Figures 1 to 7 As shown, a material bottle nesting process includes the following steps: The cartridge bottles are transferred from the filling room 1 to the first mouse hole area 4, and then from the first mouse hole area 4 to the buffer room 3. During the transfer, the first sealing door 5 and the second sealing door 6 on both sides of the first mouse hole area 4 are opened and closed in sequence.

[0021] The cartridge bottle is transferred from the buffer room 3 to the second mouse hole area 8, and then from the second mouse hole area 8 to the nesting room 2. During the transfer, the third sealing door 9 and the fourth sealing door 10 on both sides of the second mouse hole area 8 are opened and closed in sequence.

[0022] Specifically, filling room 1 provides a high-cleanliness filling environment for filling cartridge bottles with medicine; nesting room 2 provides a nesting operation environment for placing cartridge bottles into nesting boards; buffer room 3 physically isolates filling room 1 from nesting room 2; and the first mouse hole area 4 serves as a material transfer channel between filling room 1 and buffer room 3. When transferring cartridge bottles, firstly, the first sealing door 5 opens, the second sealing door 6 closes, and the first robotic arm transfers the filled cartridge bottles from filling room 1 to the first mouse hole area 4. After the number of cartridge bottles in the first mouse hole area 4 is stacked to a predetermined quantity, the first sealing door 5 closes and the second sealing door 6 opens. At this time, the second robotic arm transfers the cartridge bottles to the buffer mechanism 7 in the buffer room 3 for transport. The first sealing door 5 and the second sealing door 6 control the opening and closing of the two sides of the first mouse hole area 4 respectively. The two work together to achieve sequential opening and closing, maintain the pressure difference between the filling room 1 and the buffer room 3, and prevent the airflow from flowing due to the simultaneous opening of both sides. This ensures that the filling room 1 and the buffer room 3 are always in a state of isolation.

[0023] Furthermore, the pressure and cleanliness of filling room 1 are higher than those of buffer room 3. Both meet their production requirements in terms of pressure and cleanliness. Although the first sealing door 5 and the second sealing door 6 can seal the first rat hole area 4, when the cartridge bottles are transferred between filling room 1 and buffer room 3, the gas inside filling room 1 or buffer room 3 will be trapped inside the first rat hole area 4. When the first sealing door 5 or the second sealing door 6 is opened, the gas trapped inside the first rat hole area 4 will enter filling room 1 or buffer room 3, thus affecting its internal pressure or cleanliness. However, it should be noted that the rat hole structure is a narrow channel with a reduced opening area, and the gas trapped inside has a negligible impact on the pressure and cleanliness of filling room 1 or buffer room 3. Therefore, the cooperation of the first rat hole area 4, the first sealing door 5 and the second sealing door 6 can maximize the stability of the pressure difference between filling room 1 and buffer room 3 and avoid cross-contamination.

[0024] The second mouse hole area 8 serves as a material transfer channel between the buffer room 3 and the nesting room 2. When transporting cartridge bottles, the third sealing door 9 opens first, and the fourth sealing door 10 closes. The third robotic arm transfers the cartridge bottles from the buffer mechanism 7 in the nesting room 2 to the second mouse hole area 8. Subsequently, the third sealing door 9 closes, and the fourth sealing door 10 opens. The fourth robotic arm transfers the cartridge bottles to the feeding conveyor belt 11 in the nesting room 2 for transport. The feeding conveyor belt 11 includes a conveyor belt and clamps. The clamps are set on the conveyor belt and clamp the cartridge bottles to facilitate transfer. The third sealing door 9 and the fourth sealing door 10 control the opening and closing of the two sides of the second mouse hole area 8, respectively. The two cooperate to achieve sequential opening and closing, maintain a stable pressure difference between the buffer room 3 and the nesting room 2, and prevent airflow from flowing due to simultaneous opening of both sides. This ensures that the buffer room 3 and the nesting room 2 are always in a state of isolation.

[0025] The pressure and cleanliness of buffer room 3 are higher than those of nesting room 2. Both meet the production requirements. Although the third sealing door 9 and the fourth sealing door 10 can seal the second rat hole area 8, when the cartridge bottle is transferred between buffer room 3 and nesting room 2, the gas inside buffer room 3 or nesting room 2 will be trapped inside the second rat hole area 8. When the third sealing door 9 or the fourth sealing door 10 is opened, the gas trapped inside the second rat hole area 8 will enter buffer room 3 or nesting room 2, thus affecting its internal pressure or cleanliness. However, it should be noted that the rat hole structure is a narrow channel with a reduced opening area, so the gas trapped inside has a negligible impact on the pressure and cleanliness of buffer room 3 or nesting room 2. Therefore, the cooperation of the second rat hole area 8, the third sealing door 9, and the fourth sealing door 10 can maximize the stability of the pressure difference in buffer room 3 or nesting room 2 and avoid cross-contamination.

[0026] Therefore, by sequentially opening a first rat hole area 4 and a second rat hole area 8 between the filling room 1, the buffer room 3, and the nesting room 2, and utilizing the rat hole structure as a narrow passage, the area of ​​the connecting passage between the filling room 1, the buffer room 3, and the nesting room 2 is minimized, reducing the risk of contaminants spreading with the airflow. Furthermore, the first rat hole area 4 and the second rat hole area 8 are equipped with sealing doors on both sides for selective sealing, ensuring that the filling room 1, the buffer room 3, and the nesting room 2 will never be connected during the transfer of cartridge bottles. As a result, the airflow between areas with different cleanliness and pressure levels on both sides of the first rat hole area 4 or the second rat hole area 8 will not directly connect, thus maintaining a stable pressure gradient between the areas and providing many conveniences for the production of cartridge bottles.

[0027] It should be noted that a placement plate is provided in both the first mouse hole area 4 and the second mouse hole area 8. A limiting groove is provided on the plate. When the cartridge bottle is transferred to the placement plate, the cartridge bottle is locked into the limiting groove, thereby preventing it from tipping over.

[0028] When the buffer mechanism 7 transports the cartridge bottles, the conveyor belt on the buffer mechanism 7 drives the buffer plate 701 to move. The cartridge bottles are temporarily stored in the slots opened on the buffer plate 701. The slots limit the cartridge bottles and ensure that they can maintain a predetermined posture during transportation, thereby facilitating subsequent gripping and transfer by the robotic arm. The detection unit 702 detects whether the cartridge bottles in the slots are in place. The detection unit 702 is used to confirm whether the second robotic arm has successfully placed the bottles, and to provide the downstream third robotic arm with bottle retrieval position information to ensure that the bottle retrieval action is accurate. In this embodiment, the detection unit 702 is preferably a photoelectric sensor, which is prior art and will not be described in detail here.

[0029] The buffer mechanism 7 can temporarily store a certain number of cartridge bottles, effectively decoupling the production cycle between the filling station and the nesting station. When the downstream nesting process is briefly interrupted, the filling process can continue to supply bottles to the buffer plate 701 without stopping the machine. When the downstream resumes operation, the bottles temporarily stored on the buffer plate 701 can be replenished in time, thereby avoiding a single equipment failure that could cause a complete shutdown of the production line and significantly improving the overall stability and anti-interference capability of the production line.

[0030] A material bottle nesting process further includes the following steps: the nesting board is transported by the first conveyor belt 12 to the first lifting mechanism 13, and then transferred by the first flipping mechanism 14 to the nesting conveyor belt 15. The limiting mechanism 16 limits the nesting board. The fifth robotic arm transfers the cartridge bottle on the feeding conveyor belt 11 to the nesting board. After the cartridge bottle is nested, the nesting conveyor belt 15 transports the full nesting board to the second flipping mechanism 17. The second flipping mechanism 17 transfers the full nesting board to the second lifting mechanism 18, and then the second lifting mechanism 18 transfers the full nesting board to the second conveyor belt 19.

[0031] Specifically, during the transfer of cartridge bottles, the nesting boards are also transported simultaneously. When the first conveyor belt 12 transports multiple sets of nesting boards stacked together to the first lifting mechanism 13, the first lifting mechanism 13 lifts the multiple sets of nesting boards to a predetermined position. At this time, the first flipping mechanism 14 grabs a set of nesting boards and flips them. After flipping, the nesting boards are transferred to the infeeding conveyor belt 15 for transport. When the nesting boards are transported to the infeeding position, the limiting mechanism 16 squeezes and limits the nesting boards. At this time, the fifth robotic arm transfers the cartridge bottles on the feeding conveyor belt 11 to the nesting boards. After the infeeding is completed, the infeeding conveyor belt 15 transports the full nesting boards to the second flipping mechanism 17. The second flipping mechanism 17 flips the full nesting boards and transfers them to the second lifting mechanism 18 for stacking. After stacking to a predetermined number, the second lifting mechanism 18 descends and transfers the multiple sets of full nesting boards to the second conveyor belt 19. The second conveyor belt 19 transports the multiple sets of full nesting boards to the next process.

[0032] The limiting mechanism 16 limits the nest board in the following ways: when the nest board is transported to the predetermined position, the first power component 161 drives the limiting frame 162 to descend, the limiting frame 162 limits the outer periphery of the nest board, and the toothed plate frame 163 limits the middle part of the nest board.

[0033] Specifically, by combining the outer peripheral constraint of the limiting frame 162 with the central positioning of the toothed plate frame 163, multi-point and multi-directional composite limiting of the nest board is achieved, so that the nest board obtains a highly definite positional accuracy at the nest entry station. This ensures that when the fifth robotic arm puts the bottle into the hole of the nest board, the bottle can be accurately aligned with the hole, avoiding problems such as the bottle not being able to be inserted, bottle scratches, or nest board damage caused by nest board position deviation, effectively improving the success rate of nest entry.

[0034] After the nesting tray is reliably positioned, the fifth robotic arm picks up the cartridge bottles from the grippers on the feeding conveyor belt 11 and places them one by one into the corresponding holes on the nesting tray, completing the cartridge bottle placement operation. During this process, the feeding conveyor belt 11 continuously supplies bottles to the fifth robotic arm, which completes the bottle picking, moving, and placing action cycle according to a preset trajectory until all holes on the nesting tray are filled.

[0035] In one embodiment, a material bottle nesting process further includes the following steps: when multiple sets of nesting plates stacked together are transferred from the first lifting mechanism 13 to the first flipping mechanism 14, the separation mechanism 20 separates two adjacent sets of nesting plates. At this time, the second power member 201 drives the third power member 202 to move, adjusting the height of the insert plate 203 between the two adjacent sets of nesting plates. The third power member 202 drives the insert plate 203 to insert into the gap between the two adjacent sets of nesting plates.

[0036] Specifically, when the top layer of nesting boards is lifted to the predetermined separation height, the second power component 201 drives the third power component 202 to move vertically, precisely adjusting the height of the insert plate 203 to the boundary between the top layer of nesting boards and the adjacent nesting boards below it. Subsequently, the third power component 202 drives the insert plate 203 to insert horizontally into the gap between the two layers of nesting boards. This avoids the problem of interlayer adhesion caused by electrostatic adsorption, slight edge deformation, or residual adhesive during the stacking and storage of nesting boards. The physical insertion action of the insert plate 203 forcibly separates the upper layer of nesting boards from the lower layer of nesting boards, leaving the upper layer of nesting boards in a completely free state, which is convenient for the subsequent first flipping mechanism 14 to accurately grasp. This avoids feeding failures such as picking up multiple nesting boards at once or failure to pick up materials due to adhesion, ensuring the continuity and reliability of nesting board feeding.

[0037] It should be further explained that pressure monitoring mechanisms and cleanliness monitoring mechanisms are installed in the filling room 1, buffer room 3 and nesting room 2 to monitor the internal pressure and cleanliness of the three rooms in real time. When the internal pressure and cleanliness of the three rooms do not meet the production requirements, the staff will activate the external control equipment to make adjustments. This is existing technology, so it will not be described in detail here.

[0038] Example 2

[0039] like Figures 2 to 7 As shown, this embodiment proposes a material bottle nesting device based on embodiment one, which is applied to the aforementioned material bottle nesting process, including: a filling room 1, a nesting room 2, and a buffer room 3.

[0040] The buffer room 3 is located between the filling room 1 and the nesting room 2. The cartridge bottles are filled in the filling room 1, and the filled cartridge bottles are assembled with the nest tray in the nesting room 2. The buffer room 3 is used to separate the filling room 1 and the nesting room 2.

[0041] A first rat hole area 4 is provided between the filling room 1 and the buffer room 3. A first sealing door 5 and a second sealing door 6 are movably provided on both sides of the first rat hole area 4. A second rat hole area 8 is provided between the buffer room 3 and the nesting room 2. A third sealing door 9 and a fourth sealing door 10 are movably provided on both sides of the second rat hole area 8.

[0042] Specifically, filling room 1 provides a high-cleanliness filling environment for filling cartridge bottles with medicine; nesting room 2 provides a nesting operation environment for placing cartridge bottles into nesting boards; buffer room 3 physically isolates filling room 1 from nesting room 2; and the first mouse hole area 4 serves as a material transfer channel between filling room 1 and buffer room 3. When transferring cartridge bottles, firstly, the first sealing door 5 opens, the second sealing door 6 closes, and the first robotic arm transfers the filled cartridge bottles from filling room 1 to the first mouse hole area 4. After the number of cartridge bottles in the first mouse hole area 4 is stacked to a predetermined quantity, the first sealing door 5 closes and the second sealing door 6 opens. At this time, the second robotic arm transfers the cartridge bottles to the buffer mechanism 7 in the buffer room 3 for transport. The first sealing door 5 and the second sealing door 6 control the opening and closing of the two sides of the first mouse hole area 4 respectively. The two work together to achieve sequential opening and closing, maintain the pressure difference between the filling room 1 and the buffer room 3, and prevent the airflow from flowing due to the simultaneous opening of both sides. This ensures that the filling room 1 and the buffer room 3 are always in a state of isolation.

[0043] Furthermore, the pressure and cleanliness of filling room 1 are higher than those of buffer room 3. Both meet their production requirements in terms of pressure and cleanliness. Although the first sealing door 5 and the second sealing door 6 can seal the first rat hole area 4, when the cartridge bottles are transferred between filling room 1 and buffer room 3, the gas inside filling room 1 or buffer room 3 will be trapped inside the first rat hole area 4. When the first sealing door 5 or the second sealing door 6 is opened, the gas trapped inside the first rat hole area 4 will enter filling room 1 or buffer room 3, thus affecting its internal pressure or cleanliness. However, it should be noted that the rat hole structure is a narrow channel with a reduced opening area, and the gas trapped inside has a negligible impact on the pressure and cleanliness of filling room 1 or buffer room 3. Therefore, the cooperation of the first rat hole area 4, the first sealing door 5 and the second sealing door 6 can maximize the stability of the pressure difference between filling room 1 and buffer room 3 and avoid cross-contamination.

[0044] The second mouse hole area 8 serves as a material transfer channel between the buffer room 3 and the nesting room 2. When transporting cartridge bottles, the third sealing door 9 opens first, and the fourth sealing door 10 closes. The third robotic arm transfers the cartridge bottles from the buffer mechanism 7 in the nesting room 2 to the second mouse hole area 8. Subsequently, the third sealing door 9 closes, and the fourth sealing door 10 opens. The fourth robotic arm transfers the cartridge bottles to the feeding conveyor belt 11 in the nesting room 2 for transport. The feeding conveyor belt 11 includes a conveyor belt and clamps. The clamps are set on the conveyor belt and clamp the cartridge bottles to facilitate transfer. The third sealing door 9 and the fourth sealing door 10 control the opening and closing of the two sides of the second mouse hole area 8, respectively. The two cooperate to achieve sequential opening and closing, maintain a stable pressure difference between the buffer room 3 and the nesting room 2, and prevent airflow from flowing due to simultaneous opening of both sides. This ensures that the buffer room 3 and the nesting room 2 are always in a state of isolation.

[0045] The pressure and cleanliness of buffer room 3 are higher than those of nesting room 2. Both meet the production requirements. Although the third sealing door 9 and the fourth sealing door 10 can seal the second rat hole area 8, when the cartridge bottle is transferred between buffer room 3 and nesting room 2, the gas inside buffer room 3 or nesting room 2 will be trapped inside the second rat hole area 8. When the third sealing door 9 or the fourth sealing door 106 is opened, the gas trapped inside the second rat hole area 8 will enter buffer room 3 or nesting room 2, thus affecting its internal pressure or cleanliness. However, it should be noted that the rat hole structure is a narrow channel with a reduced opening area, so the gas trapped inside has a negligible impact on the pressure and cleanliness of buffer room 3 or nesting room 2. Therefore, the cooperation of the second rat hole area 8, the third sealing door 9, and the fourth sealing door 10 can maximize the stability of the pressure difference in buffer room 3 or nesting room 2 and avoid cross-contamination.

[0046] Therefore, by sequentially opening a first rat hole area 4 and a second rat hole area 8 between the filling room 1, the buffer room 3, and the nesting room 2, and utilizing the rat hole structure as a narrow passage, the area of ​​the connecting passage between the filling room 1, the buffer room 3, and the nesting room 2 is minimized, reducing the risk of contaminants spreading with the airflow. Furthermore, the first rat hole area 4 and the second rat hole area 8 are equipped with sealing doors on both sides for selective sealing, ensuring that the filling room 1, the buffer room 3, and the nesting room 2 will never be connected during the transfer of cartridge bottles. As a result, the airflow between areas with different cleanliness and pressure levels on both sides of the first rat hole area 4 or the second rat hole area 8 will not directly connect, thus maintaining a stable pressure gradient between the areas and providing many conveniences for the production of cartridge bottles.

[0047] In one embodiment, a material bottle feeding device includes a buffer mechanism 7, a feeding conveyor belt 11, a first conveyor belt 12, a first lifting mechanism 13, a first flipping mechanism 14, a feeding conveyor belt 15, a limiting mechanism 16, a second flipping mechanism 17, a second lifting mechanism 18, and a second conveyor belt 19.

[0048] The buffer mechanism 7 is disposed in the buffer room 3 and includes a buffer plate 701 and a detection unit 702. The buffer plate 701 is used to transport the cartridge bottle, and the buffer plate 701 has slots for temporarily storing the cartridge bottle.

[0049] The two sets of detection units 702 are respectively disposed at both ends of the buffer mechanism 7, and are used to detect whether the cartridge bottle exists in the slot.

[0050] The feeding conveyor belt 11 is disposed in the inlet chamber 2 and includes a conveyor belt and a clamp. The clamp is disposed on the conveyor belt and is used to transport the filled cartridge bottles.

[0051] The first conveyor belt 12, the first lifting mechanism 13, the first flipping mechanism 14, the nest-entry conveyor belt 15, the second flipping mechanism 17, the second lifting mechanism 18 and the second conveyor belt 19 are arranged in sequence for transporting the nest tray and the filled cartridge bottle.

[0052] The limiting mechanism 16 includes a first power component 161, a limiting frame 162, and a toothed plate frame 163. The limiting frame 162 is disposed on the toothed plate frame 163, and the toothed plate frame 163 is mounted inside the limiting frame 162.

[0053] Specifically, the buffer mechanism 7, the feeding conveyor belt 11, the first conveyor belt 12, the first lifting mechanism 13, the first turning mechanism 14, the nesting conveyor belt 15, the limiting mechanism 16, the second turning mechanism 17, the second lifting mechanism 18, and the second conveyor belt 19 constitute a complete transportation line for the nesting boards, facilitating efficient transportation of the nesting boards. The first conveyor belt 12 and the second conveyor belt 19 are the same mechanism but transport in different directions during operation. The first lifting mechanism 13 and the second lifting mechanism 18 are the same mechanism but lift in different directions during operation. The first turning mechanism 14 and the second turning mechanism 17 are the same mechanism but turn in different directions during operation. Furthermore, the first conveyor belt 12, the second conveyor belt 19, the first lifting mechanism 13, the second lifting mechanism 18, the first turning mechanism 14, and the second turning mechanism 17 are all existing technologies and will not be described in detail here.

[0054] In one embodiment, a separation mechanism 20 is included, which is disposed on both sides of the first lifting mechanism 13. The separation mechanism 20 includes a second power member 201, a third power member 202 and an insert plate 203. The third power member 202 is disposed at the movable end of the second power member 201 and the insert plate 203 is disposed at the movable end of the third power member 202.

[0055] Specifically, when the top layer of nesting board is lifted to the predetermined separation height, the second power component 201 drives the third power component 202 to move vertically, precisely adjusting the height of the insert plate 203 to the boundary between the top layer of nesting board and the adjacent nesting board below it. Then, the third power component 202 drives the insert plate 203 to be inserted horizontally into the gap between the two layers of nesting board. This avoids the problem of interlayer adhesion caused by electrostatic adsorption, slight edge deformation or residual adhesive during the stacking and storage of nesting boards.

[0056] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
